I take my life for granted. I take the adoration my two year old son has of me, for granted. I take my wife's love and caring for granted. I do all this, thinking that what I build today will provide a better future for all of us. And I could be wrong.

I could shut my laptop when he squirms his way between me and the desk and wiggles his way on to my lap. I could switch my context when my wife sits down next to me aching for a conversation. I could spend more time with both of them.

I can pretty much be sure when I say I will not be the next Zuckerberg. There are many things that vy for my attention throughout the day and night. But there is only one thing both of them needs and which I squander.

I do not want to look back and regret. I am going home right now and I am going to kiss my wife and hug my kid.

Ciao.

I've posted this a few times now, but always feel it is worth posting again when I read these types of blog postings and see the comments they inspire. It has been attributed to Jorge Luis Borges, but many disagree with that. At any rate, it inspires me...

"Instantes"

If I were able to live my life anew, in the next I would try to commit more errors. I would not try to be so perfect, I would relax more. I would be more foolish than I've been, In fact, I would take few things seriously. I would be less hygienic. I would run more risks, take more vacations, contemplate more sunsets, climb more mountains, swim more rivers. I would go to more places where I've never been, I would eat more ice cream and fewer beans, I would have more real problems and less imaginary ones.

I was one of those people that lived sensibly and prolifically each minute of his life; Of course I had moments of happiness. If I could go back I would try to have only good moments. Because if you didn't know, of that is life made: only of moments; Don't lose the now.

I was one of those that never went anywhere without a thermometer, a hot-water bottle, an umbrella, and a parachute; If I could live again, I would travel lighter. If I could live again, I would begin to walk barefoot from the beginning of spring and I would continue barefoot until autumn ends. I would take more cart rides, contemplate more dawns, and play with more children, If I had another life ahead of me.

But already you see, I am 85, and I know that I am dying.

I didn't know Derek, but reading this I'll miss him, but thank him for this.

Between this post, "Cranking" (http://www.43folders.com/2011/04/22/cranking) and the fact I have a second child probably coming Very Soon Now, I have to admit I'm sitting back and thinking hard about where I've spent, and am spending my time. I'm thinking about all the wasted time and opportunities I've accrued over the past 31 years.

I'm thinking about all the time spent arguing with people on the internet and giving up my free time to change some small part of the world, and not playing with my almost four year old daughter, or talking with my beautiful wife.

Take stock in your life and make sure you're following your passions. Make sure you try to remember and capture every moment before it's gone. Change the world while you're still here.

Appreciate the world while you're still here.

This post has me wondering about the health of my figurative soul. Not because it didn't move me - it did. The last sentence definitely brought tears to my eyes when I first read it, and then again when I thought of it again.

No, the reason it has me worried is because although I have people I care about, I don't think I love anybody so much that I'd rather spend time with them than work/learn/create things. When I think about starting a family, I worry about how much I'll regret not being able to devote my full energy to building intellectual edifices out of math, bits, and music. But I see most people here saying the opposite.

I'm trying to tell myself that this is only because I don't have kids. Surely, if I had kids, my whole perspective would change, and I'd become a more complete human being, right?

This post made me glad I'm living the life I'm living now. I'm 31 years old -- 32 in a month -- and while my daughter is at school, I spend the day programming, running errands, reading, chatting with RL friends via IRC, playing video games, browsing Reddit and HN. When she gets home, I make sure she does her homework, I make dinner, I sleep.

Every morning I get to wake up next to a beautiful, brilliant girl who's several years my junior but emotionally more mature than me. I have never felt better about another person in my life.

I have no bills, I maintain a modest lifestyle and am attending university for a degree in a subject matter that simultaneously I love and will make me some extra money down the road when I need it.

Every day, I set my own schedule, fitted around picking up & dropping off my daughter at school. Beyond the normal stresses of being a single parent, my life is astoundingly, remarkably, wonderfully, joyously stress-free. For the first time in my life.

Reading Derek's post has affirmed the decisions I've made to put me in this position. I regret nothing, and just about every day is awesome. If you've read this far, please don't take this as shameless bragging. It is a sincere expression of gratitude to Derek, and a grinning shout of relief at the sky that I have let so many unnecessary, trivial things fall away from my life over the past few years.

You know, this is going to sound callous, but everybody dies. Any one of us could be killed in an accident tomorrow. All this "live without regrets" is just flatly impossible, and a waste of time to sit and worry about. Every choice has opportunity costs. I can't believe that anyone gets through life not wishing he could take back some decisions he made, but even if this were possible, those changes would have their own unintended consequences.

You are who you are. You love what you love. The world isn't perfect. Don't sit and think your priorities are "wrong" all the time.

I often think that some people die "before their time" so that other people receive a unique, golden opportunity to learn to reprioritize their life. Thanks for that, Derek, again. (Didn't know you before.)

And yet it's real difficult to make good use of that opportunity; we people are so stubborn that we rarely change for the better of ourselves or for other people even if somebody goes lengths and dies to remind us that we won't be here forever.

Even worse, it might take a whole row of people dropping dead until we manage to corner ourselves into a position where we can no longer give ourselves a choice to postpone any necessary changes in our lives. But that's how it works, so can't complain.

I'm nearing that point myself, currently. It haunts me, all the time closer and closer. I can go only so far this way anymore until I have to take that other road and start living a bit differently: start living a life that is completely mine and not partially borrowed from anyone else.

I'm not there yet.

Maybe I need to bump into a few more deaths before I get zapped into alignment with all things relevant. I can just anticipate now, and that makes me both scared and thrilled.

As a kid I spent a lot of time wandering around a cemetery near my grand parent's house, I read tombstones of folks, some of them younger than I was; That somehow numb my fear of death as I considered each day alive as a gift. Now as a father I fear death not because of actually leaving this world but dying before my kids are old enough to take care of themselves. I see Derek had the same fear and that must have been devastating for him, so sad. I pray and wish his daughters and wife well.

I was about to cry but didn't happen. I've been in this position before and I've had tears rolling down. But not this time. I have learned and I know that it's not as simple as taking things for granted or not. Those that are running to their wives and kids right now are just emotionally hijacked by the rush of whatever neurotransmitter is triggered in this situations. Tomorrow it will be different and a week from now even more. And that's OK. Life goes on and we have to explore other things, pursue new goals; and if we're wise enough, we'll find a way to find peace within ourselves.

Funny how some people just stand out in your memory, even after years have passed. My heart goes out to his family and friends right now. He will be missed by many of us.

I hope this reminds people, especially in light of recent news, that cancer kills far more people in this country than terrorism ever has or will. We must do what we have to to keep our nation safe and secure, without doubt, but if we could spend this amount of money towards medical research and stop politicizing it, we could achieve wonders.

While this was a beautiful and very moving post, I disagree with this:

> I haven't gone to a better place, or a worse one. I haven't gone anyplace, because Derek doesn't exist anymore. As soon as my body stopped functioning, and the neurons in my brain ceased firing, I made a remarkable transformation: from a living organism to a corpse, like a flower or a mouse that didn't make it through a particularly frosty night. The evidence is clear that once I died, it was over.

With all due respect to Derek, and it's remarkable he was standing by his beliefs until the very end, he has no way of knowing that's what happened.

I'm happy for John, and this is great news for the Khan Academy. But I have to admit my reaction was mixed about his initial plans to focus on the iPad. On one hand, this is tantamount to saying you want to ensure that rich kids have better access to educational materials. Relative to the rest of society, children of parents who can afford an iPad are probably the least needy re educational tools. On the other hand, they're probably the ones who will make the most use of the tools.

It is very hard to leave/scale-back unfinished business or commitments but it is a very important step before starting something new and big. I know many creative people who have tons of projects and commitments that they can't bring themselves to leave and as a result, they never have enough time to concentrate fully on their next big things. I highly commend John for making the tough decision of leaving Mozilla and lots of personal projects so that he could do something big.

The site is currently quite hard to navigate around or search. Now that even talents like John have started to join the academy, I'm pretty sure, the site will definitely provide a better experience. Good for Khan, the academy and the education system

Oh boy, this reminds me so much of One Laptop Per Child (OLPC). Almost every geek cries out "I want this thing now and play around with it." But the inventor is like "No, no, its all for the kids. You can't have it."

The OLPC Hardware could have been a huge commercial success if it had been gone into production soon after the orignal presentation. But no, it needed Acer and their EEE-PC to satisfy that demand.

Why develop a "universal purpose something" specifically for children? You're not a child anymore so its way easier to build something YOU want than imagine what exactly a child wants or needs. In fact, I'm sure this guy wants the USB-PC more than anyone else on the planet. Also, if you mass produce you bring down prices anyway.

But most important, everyone knows what children want in general: They want to be just like their adult idols!
Don't tell kids: "This is for you. I wish I had it when I was a kid. Now, have fun, while daddy works on his Mac."

After my initial excitement of "wow, cool" and "wow, tiny" and "wow, cheap" wore off, I'm also becoming skeptical about what niche this fills for educators.

Why? Because an old PC with equivalent specs is essentially free (anything from ~2000 onwards.) Thousands of them, desktop and laptop, will be being recycled or landfilled every day.

Linux on x86 hardware is standard enough that you can effectively call it a standard platform for developers, already, same as this.

The remaining key advantage (I guess) is size. And maybe the fact that it's easier to get kids excited about playing with a tiny brand new board than with a 10 year old computer.

I would like to see some other concepts taught using these devices. Specifically clustering, meshing, cloud etc.

You get a bunch of these devices and arrange them into a cluster/cloud of nano-nodes and teach kids (teens) how to setup clusters of webservers, memcache, micro-dbs etc.

You effectively use the devices to teach large technical infrastructure with tiny physical representations.

Here is how I would do it:

I would whiteboard out a network diagram showing the different layers of tech infrastructure in contemporary cloud designs.

Draw the nodes and connections.

Define the role of nodes in each layer:

Firewall, load balancer, web server, memcache, app server, db server

Then do a micro-config for each of these and run them on the little buggers.

Get velcro tape and tape them onto the diagram in the appropriate location.

Physically wire them all together.

Have it run a website that the students build.

Run analytics...

This would be the ultimate in showing them how The Tubes actually provide them with the data they view every day.

By drawing this, then physically attaching the units to the diagram and running it there will be ZERO confusion and I guarantee that every student will grok the internet more fully.

The thing does not need to be high performance - but it does need to be fault tolerant.

Have the students pull devices out while its running and they are watching monitoring. Have some subjectively F5-ing the little site they made while you drop a few nodes.

Hell, I am ready to do this... anyone want to help me get some of these devices/similar devices?

Earlier submission, much discussion:

http://news.ycombinator.com/item?id=2517136

I honestly don't see how this is gong to encourage people, especially kids, to further wonder about how computers work, and what actually happens. It's smaller, and if anything even less accessible than a desktop machine.

I learned about computers and computing by building my own from a Z80, 8KB RAM, 8KB ROM, random logic, etching my own circuit board and soldering the components and sockets in place.

Should kids do that these days? Would it help?

I dropped them an email with some questions:

    > 1) How long do you think it will be before the boards become available?

I'd say three or four months. As you can see from the screenshots, we
have usable Linux, but we're waiting to get final versions of the the
chip from our supplier.

> 2) Are there any plans for a version with onboard ethernet?

I don't think we're likely to do onboard Ethernet; we will have an
onboard 3-port USB hub so people can add an external adapter.

> 3) Are there any plans for a version with onboard wifi?

Yes. The final version (though maybe not the first distributables)
will have onboard WiFi (probably 802.11n) in the price point.

> 4) What are the power requirements, both under load and at rest?

At rest I'd say 50mW (we could trim this if it was really important,
but it gets a bit fiddly below this point), under serious load
(original XBox class graphics or 1080p30 H.264), 700mW.

I'm looking at this as a replacement for the Bifferboards [1] I often use in projects, they're similarly priced (£35), but significantly lower specification.

This is neat. Now we need some Linux environments for kids to make cool stuff. L-VE [1] is a neat Lua-powered game development library, but it's fairly source-code oriented, which may be a barrier for some kids. When I first learned programming, Game Maker [2] was extremely useful. It had a drag-and-drop GUI which was easy enough to mess around with until figuring out how to do things in it's built-in (and extremely forgiving) programming language.

Sorry, but how does this teach kids how computers work? What you do is educate them about boolean algebra, then explain how different boolean components can be bought in a microchip. After that you explain how large combinations of those make up something which can process 0's and 1's and thus (which they should already know by then) strings of 0's and 1's.

The brighter kids will already start trying to make something 'work' out of that. You continue further about how a CPU works, completely in the language of boolean components. And then they get to design and build one themselves.

That will really teach and show them there is no magic and how it works. Even with the insanely small and complex systems you have now, you can rest assure that in the core they are basically just like the one you made when you were in school.
This kind of practical way of working with hardware (even simulated), gives a lot more pleasure and teaches kids computer hardware design, cpu design, microcodes, assembly and tons more.

I was taught from 'Micro computers' by A.J. Dirksen (ISBN 9789021015934); it (+ the teacher) gave me enough insight to quickly learn Z80 assembler, 68k assembler and add / replace hardware on my '80s computers.

EDIT: I forgot; it would be really stupid to not release this to the masses. Everyone wants one, but only the kids can it; I agree with the rest here; that makes no business sense. Charities are businesses too.

jeza 3 days ago 1 reply      
If you want to teach kids about hardware, wouldn't it be better to supply them with something slightly larger where they can install the CPU, RAM, etc. Perhaps supplied as a kit. At least that way they can at least identify the different components that make a computer what it is. They might also have a choice between selection different components, say a memory card vs. a small laptop hard drive, network cards, etc. As a learning tool, I think that'd be better value for $25 than a tiny USB stick sized thing. I think the fun of assembling would outweigh the coolness of being tiny.

What about the cost of TVs and keyboards?

I like the idea, but I don't think the place for this device is in schools.

In fact, I hope computer science never gets into high school curriculum, it will only make students hate programming. Just look at math. Programming is even harder; and chances are if you're a programmer you're not really likely to become a high school teacher. Conversely most high school teachers will not know how to program.

Very cool, but i'm not sure how he can get it to an actual cost of $25 unless it's heavily supported by donations, grants, "give one get one" etc. For small runs (<10K?) the cost of production has to be a large multiplier on that.

Other options in this space (far more expensive! but similar ARM on a board style)

Awesome! The current a transistor can put out is porportional to the width over the length and chip designers usually want wide transistors[1], but wide transistors take up space which causes more line capacitance. This innovation will let people put more, wider transistors in a given area which will both increase the current they're putting out and decrease the capacitance they're fighting against, leading to higher frequencies[2].

[1] Wider transistors also cause more capacitance for the other transistors that are driving them, but for most modern designs this is smaller than line capacitance.

[2] Having transistors closer together can also help overcome speed-of-light delay. This can be important in caches.

EDIT: Also, some stuff I didn't notice until reading the Anandtech article is that the thinness of the silicon will give you the same artificial limitation of the depletion region that SOI does, leading to the same accelerated inversion. Oh, and better isolation from the base too. I don't think that I can explain that succinctly for non-EEs so go read Wikipedia on MOSFETs if you're interested.

From what I've heard, using 50% as much power for the same performance as the previous generation still will not be sufficient to bring Intel's Atom performance/energy consumption ratio to that offered by ARM chips. However, it's a huge leap in the right direction. Add better-designed power-saving features on the next generation of Atom chips, and future process shrinkages, and it's easy to see ARM's lead getting chipped away until it's gone.

I think this will mostly help increase the life expectancy of the Moore's Law by another 10 years or so. When we'll get to 11nm or whatever is the limit, we'll just start stacking layers of transistors on each other. That will only work until the chips become too thick, though.

I just ask for an email address. I then email an auto generated password to the user. Their first login with the password I sent creates the account and takes them to their profile page which allows them to change their password or fill in other non essential info.

This system has a few benefits:

* No annoying "username already taken" or "password too short" rejections that make people give up.

* No junk accounts that haven't been verified since I don't create an account until the first login

* Person's email history has a record of their password if they're the type of person that doesn't care to change it.

* Since I'm really lazy, the account creation code is also the password recovery code. It just emails a new password.

I don't see any downsides with my system.

I'm surprised they didn't mention what I consider the greatest cardinal sin of sign-ups: if you're not validating email addresses, start the user's session as soon as they register, instead of making them re-enter the same info again into a login box. (Even if you're sending a validation email, you could allow the user to postpone validating, or at the very least, log them in automatically upon clicking the link in their email.)

Not sure if it was accidental or not, but we ended up with the single simplest sign-up/login I've ever seen. We've even received a few emails from users alarmed at how simple it is. We're considering adding a few artificial steps (like filling out a profile) so that users feel more like they are creating an account.

1. Click login

2. Choose account provider

3. Grant us authorization access

4. Done - we pull your name and email address from the OAuth information and autopopulate your user profile.

At this point we don't strictly need any more information, and adding more account providers doesn't increase the number of steps. Actually, when we only supported Google accounts we didn't have a step #2.

We may start asking people some more questions, but for now signing up and logging in virtually identical user experiences.

So now only users with Javascript enabled can use your website. I'm sure that will increase conversion.

Not true anymore.

> you can create a honeypot form field that should be left blank and then use CSS to hide it from human users, but not bots

Apparently those of us that are blind, browse from the terminal, or use automated form-fillers are bots and not users too?

Some of this advice is good, some of it is very obvious and widely implemented, and some of it is bad. As the author has left determining which are which as an exercise to the reader, I'm not sure they know either.

Another thing that I'll start to experiment with is delayed confirmations.

The confirmation step via emails is one of those things that has been copied over and over, without knowing, in many cases, what problem it addresses in the first place and if it's crucial to one's particular situations.

I think having to interrupt your visit to log into your email, is another speed bump to a smooth registration process.

A better approach, in my opinion, would be to let users just start interacting with your service right away. Give them 5 to 7 days to confirm their account, after which it is automatically suspended. You can let them know the next time they try to login that they never actually clicked the link they received via email a week earlier. The timeframe is long enough that they can actually use the service with no hassle and it's short enough that they won't have forgotten which email and password they gave during registration.

Of course, if the operations they're trying to perform in your site are sensitive enough (e.g. purchase, sale), you should let them know that it requires an immediate confirmation of the email address.

Other unrelated advices:

- if you use the email as a login name, then allow users to have whatever handle they'd like. i.e. don't make the username unique. Also, allow spaces in that field. e.g. StackExchange.

- under no circumstance should you keep an unencrypted record of the password. It's tempting to think that in the name of user friendliness, whenever someone loses their password, you will just send it back to them. As soon as I see my password sent to me in an email, I usually logon to the website, change the password to 12345 and depending of the sensitivity of the data kept by the service (e.g. web hosting), I would consider stopping using it altogether (Ironically, I've had cases of websites telling me that 12345 as a password isn't secure enough for their service, after they'd sent me my password via email).

Not true anymore. What you could do is add a hidden field with value=encrypt(timestamp+salt) and only accept the form if the decrypted timestamp is at most x hours old. If you want to further restrict it, you could also add the IP to the encrypted value. This will fail if a user gets a new IP between loading the form and submitting it (laptop user moving around, VPN gateway changes etc).

In my option there is a lot of bad advise in there:

  Require Users to Type Their Password Only Once

At least I am very likely to overlook a typo, but less so to make the same typo twice.

  Allow Users to Auto-Fill Their Payment Address From the Shipping Address

Why not make a check box "same as billing address"? That way if people make a mistake they only have to correct it once.

  Don't Check the Newsletter Option by Default. Offer a Preview Instead

And how many people will click on that preview ?

  Spambots can't fill in the field because they can't interact with objects in client-side JavaScript

sure

  Allow Users to Unmask Their Password

If I saw this I really would have no idea what the checkbox "check password" does.

  Make the “Submit” Button as Wide as the Text Fields

Never had problems with being insecure which action I was about to take when I logged into facebook.

  Allow Users to Log in Via Facebook, Twitter or OpenID

I don't have twitter, OpenID confuses me and I hate websites where I have to login with facebook.

Thats a great article. The first two points inbound the most interesting... Let the user choose a username after they sign up - I wonder what sites do that now, it's a good way of removing a barrier to entry.
The second I'm not so sure about... Having the user enter their password once and showing it to them - I'd be worried that you might lose users to simple typos.
Most of the rest is kind of common sense but a great reminder that the login/signup system is probably the _most_ important feature of a web site, since it's the one users interact with most often.

I'd be very careful when considering and implementing most of these ideas. While the sentiment is correct (make users' experience easier), many of these approaches have pitfalls or require fallbacks.

Your signup and login pages MUST be bulletproof.

Autofilling city/state from zip, for example, requires an updated database of postal codes, but users will often consider your autofill city as "wrong", since they use a different district/locale name. Make sure users can override your guesses.

As someone who uses LastPass, don't do this. It (usually?) won't let LastPass log you in to the site nor save the log-in details for a new site - a huge pain in the ass.

On another note, if I fail to enter the right details or check the right boxes, don't let me start all over again! Opera is great in how it lets you go back and retain all entered data, but other browsers are not as good at this.

From my experience of building web applications only two pieces of information are EVER required at registration time:

1). Email address - unlikely to be forgotten and is useful, ie you can then contact the user

2). Password - so the user can access the site. And I agree, dont ask twice for this, as long as you have a password reset feature.

Any further information can be obtained once the user is inside the system - and full explainations can be given as to why particular information is required.

And never use captcha! There are a millions tricks that you can employ to avoid bots.

There's a meme to be spawned about things that work like the parole narrative in The Shawshank Redemption, where good things only happen when you decide to stop giving a shit about them. Deal closing of all sorts definitely fits it.

In the meantime, perhaps console yourself this way: you haven't found the pitch that's opening investor wallets yet, and maybe that's a good thing. Maybe the pitch you're using isn't your best bet; maybe a "yes" at meeting 38 would have put you on a bad path.

My friends and I got a high-seven-figures "yes" in '99 that ultimately killed our company.

Meanwhile, Matasano went through exactly what you did in 2005; every company that found a "yes" got dead as a result. We're relieved to have dodged the funding trap.

Best of luck to you. You don't need gatekeeping investors to succeed.

While the entire post is both cathartic and poignant, one line stood out for me because of its brutal honesty.

Am I jealous of other companies' success? I would be lying if I said no.

Thank you for saying this. I've always wanted to, but feared I'd be called out for it. In public. In fact, I think it's part of what keeps the fire burning inside - that constant hunger to try and figure out why some folks are plain better / more successful at the game, and then trying and internalizing / applying those lessons.

And it can get frustrating when you can't replicate / emulate what others have achieved seemingly easily. As a corollary, this is probably why Jack Dorsey and Dennis Crowley are enigmas unto themselves.

An important aside: Chad, I'm someone who has tracked (and may I add envied) the Notifo story. And I admire the work you've done, from fanout.js, to snagging Paul for a co-founder, to HN for Android, to PicAFight, to GramFrame, to Vorepad........I've found myself in awe of how prolific you've been (and you don't even know me).

It's possible you've been doing one thing too many (because you love APIs and can't keep from tinkering with them). What I'm convinced of, is that you have the talent, the work ethic and an incredible co-founder. All the best, I'm hoping I have to transition back into pure envy real soon.

If you're not ready to sacrifice everything you have, possibly including your health, then work on your project on the side. You really do have to be crazy to be an entrepreneur.

Nicely done. I especially liked "We let them [the investors] dictate our path with their negative signaling instead of listening to our guts."

This trap is something that is so easy to fall into and so painful to pull out of. My first startup had a 'star' VC fronting it, he loved the concept but didn't really understand that his vision was often in conflict with the founder's vision. That really hurt as the company was ripped too and fro trying to achieve a couple of really orthogonal goals.

Tom Lyon once told me that really it takes three startups before you 'get it'. One which is a somplete disaster, it helps you see what you did wrong and what can go wrong. One which isn't a complete disaster but exits sideways, which is to say you work at it day and night but when it exits you find yourself exactly where you were when you started. Then the third one where you know what to expect, you have a solid idea of what not to do and you keep laser focused on getting in, getting done, and getting it shipped.

It is very hard though, always.

Here's another bit of sunshine to brighten your day:

Looking at the stats, and hanging out on HN for a while, it occurs to me that having a successful startup might be the coolest thing you do in your life business-wise. A zillion guys kick ass on a startup after college, only to hang around the community for decades afterwards, looking to write a check, trying to get back in on the action. As rare as profitable startups are, repeat entrepreneurs are even rarer. Maybe you're that one-in-ten-million guy. Probably not.

So if it takes 20 years, I wouldn't sweat it. If there's one thing I've learned to believe in, it's that everything in startups takes a lot longer and is a lot harder than you think it is. So even when you imagine this really tough and difficult journey lasting for years, it's probably going to be worse than that.

I'm not saying that to encourage you to give up, I just wouldn't spend a second of my time waiting for the calvary to arrive, because they aren't.

I think that the "making something people want" at the right time is the hardest part, and maybe distribution as well.

Execution is important.

But I think many people have the skills to create what ends up being successful.

Take Groupon for example. It made something a lot of people wanted. Could most people on Hacker News have made it? Sure.

But Groupon created it before anyone else (I might be wrong about this?).

Another example is HN. Pg has said that what he thinks users want most are quality articles and discussion.

While it's "just a forum", I think Pg is right for not adding a lot of features, or spending the limited time he has working on the UI, and instead focusing on how people can discover quality articles and make/read quality comments.

"Make something people want." It's simple, but it sure isn't easy.

It's anecdotes like these that reinforce my belief that for a bootstrapping pre-success founder it's easier to focus on revenue rather than investment. The growth curve might be slower, but the friction you face as a first time entrepreneur trying to raise money is deadly.

Great post.

I've also had "Startup depression" where I didn't sleep for 1 week and was totally unproductive for a grand total of 2-3 weeks. Ever since then I stopped recommending doing startups to my friends.

We've also experienced the "You're Nobody until you're Somebody problem." The work-around we're trying right now is to bring a (non-technical) "Somebody" onboard as a partner/founder, who is also, unlike us, located in the US where our market is.

Location has also come up in this thread. Early on I thought that thanks to the Internet location matters "less". Not true. You have to be where your investors/customers are. Deals require massive face time.

This is the reality. I well remember hearing Steve Blank speak when he said nine out of ten of us in the audience would fail. But he said each of you are thinking that you will be the one who succeeds and are feeling sorry for the other nine. I didn't realize it at the time but he defined what it is to be an entrepreneur for us.

I think startups are like poker.

- they're 80% luck and 20% skill

- but the people who have been successful work hard to promote the idea (which they also generally believe) that they're 20% luck and 80% skill.

"The less you need money, the more people want to give it to you." - some advice I have heard about finances. Applies to businesses selling a product, startups looking for money, and, especially well, to scholarships.

The best indication that people should invest in you is that you don't need them to invest in you at all.

Great post! The thing that really rang true was the part about the fundraising/depression/derailment, and how that can lead a start-up to consider some random/terrible offers that would otherwise be totally bogus. Paul talked us off a few bad-acquisition cliffs as well.

We certainly went through all of that at Jamglue. It's absolutely true that being a founder, especially the fundraising part, requires a really thick skin.

Each time I think about doing another startup, I start having flashbacks to broken termsheets, bullshit EBITDA projections, and VC's telling us that they could introduce us to Quincy Jones (I swear, at least 7 different people told us this). When we came out of our fundraising stint (penniless), we realized that our product had suffered and we were completely broken people.

The ability to be self-aware about the emotional roller-coaster is invaluable, and essential to forward progress. Thanks for this honest account so that others can make some sense about what they are feeling.

Are starups really that hard, or do they just require certain skills? Is it luck? Are you in the wrong place in the wrong time? Do you just lack the necessary skills? Do you lack the social support?

In school, you just gotta do what the teacher tells you to do, and you get an 'A'. You get a job and you just gotta be able to do what your boss wants you to do. Startups require you to find your own nitch, and do something different. No one is telling you what to do.

So, you can work real hard and work like before, but end up pursuing an empty hole. However, is this really harder?

Your problem are irrationally high expectations. Most of us suffer from naive optimism and that is a great motivator, a harmless one if we use it to fuel our enthusiasm while working late at night. The problem arises when dehydration makes you see an Oasis everywhere, when you become delusional. We humans suck at calculating expected value, particularly when there are huge outcomes with very very very tiny probabilities. That's why so many people play the lottery and that's what you're doing: playing the lottery, and there's nothing you can do to win it. Even with your perseverance and focus, with your knowledge and hard work, if you win it you are just very lucky. On the other hand, there's a lot you can do to be happy. With your youth, your wife, your intelligence, and your hard work, if you don't reach a state of emotional satisfaction then you are very unlucky.

My advice to you would be to define your threshold of success as something you can control. Focus on your surroundings. Get one client and satisfy him. Don't do it for money but for the pleasure of having an impact on somebody else. You can be your first client too; in fact, that's what we did when we built Spottiness: it's for us, we do what we can, we are nobodies and we don't care.

As an entrepreneur reading your post, I couldn't sympathize more with your situation. Startups are hard, startups are not for everyone and as Arrington would say, you are not a pirate until you start a company.

However, I would change your attitude a little bit. In your post you seem to focus on your sacrifices and being jealous of other successes. Well, when I see that Color and other startups raise a ton of money, I get SUPER excited! Why? Because if they can do it, I can do it too!
As far as sacrifices go, realize that you are still better than 90% of the entire world. Being grateful for things that we have is a force multiplier. I am grateful for what I have and having the opportunity to build a company in Silicon Valley is a life long dream come true. Dreams are bigger than sacrifices. If you believe in yourself, you believe in your product, your customers will believe in you and your investors will too.

Good luck. And enjoy the journey, in the end life is just a game (whether you are a doctor, investment banker or entrepreneur, we all have finite amount of time on this planet).

Thanks for sharing this Chad. It means a lot to me, for someone who is just getting into startup life with wife and kid to support, giving up a well-paid 'secure' day job.

An inspiring poem shared by my friend. Was read out by Winston Churchill at the beginning of Second World War.

-----------------------------------------

SAY not the struggle naught availeth,
The labour and the wounds are vain,
The enemy faints not, nor faileth,
And as things have been they remain.

If hopes were dupes, fears may be liars;
It may be, in yon smoke conceal'd,
Your comrades chase e'en now the fliers,
And, but for you, possess the field.

For while the tired waves, vainly breaking,
Seem here no painful inch to gain,
Far back, through creeks and inlets making,
Comes silent, flooding in, the main.

And not by eastern windows only,
When daylight comes, comes in the light;
In front the sun climbs slow, how slowly!
But westward, look, the land is bright!

----------------------------

Here is the paraphrase shared by the friend:

Don't say that the long struggle [against tyranny and injustice] is of no avail;
don't say that all your efforts, and all the injuries you've sustained, were in vain.
Don't say that the enemy's just as strong as ever;
and don't say that nothing's changed for the better!

If the things you hoped for haven't happened, well, maybe the things you're scared of won't happen either.
Perhaps over there on the battlefield, now obscured by smoke,
your comrades are chasing the enemy away,
and all they need to ensure victory is that you go and join them.

Look! Those waves don't seem to be making much headway,
even though the tide's supposedly coming in.
But far behind you, unseen creeks and inlets are swelling with incoming waters:
the sea really is on the move after all!

Look! The eastern window you're sitting at
isn't the only place affected by sunrise;
from there, yes, it's true, the sun hardly seems to moving up the sky at all"
but cross the room and look through a westward-facing casement: see how the whole landscape's already flooded with light!

Clough had just personally witnessed how Garibaldi's brave attempt to help preserve a new Roman Republic had been foiled when the forces of reaction (led, ironically enough, by the French) had successfully brought the Siege of Rome to an end in 1848. He was trying to cheer up fellow-supporters of reform and of independence for Italy. They were all feeling pretty downhearted. That's the historical context.

So startups the YC way are hard. The sacrifice is self-inflicted, and avoidable - just give up more of your company up front, or choose a more visible partner, or have a spouse that has a real income to start with, or work at BigCo then quit and create something they need and lease/contract it back to them, etc.

Its winning the lottery that is hard, and only because you make it hard on yourself for that big prize.

"if you are having trouble putting together a round in the first few weeks of actual investor meetings, just say, "screw it," and get back to working ASAP."

What I find interesting, is that you can build a fairly large and profitable bootstrapped company, but unless you got VC money in the Silicon Valley the standard way, from the right people, you will always remain a bit of persona non grata, not particularly liked by Arrington, Techcrunch and the establishment. There will be no hype, no press, even if your revenue is larger than say Digg's in its heyday. I am speaking from experience, but I know of many other examples.

Thanks for the great post! I don't think you'll ever quit until you succeed. I think the key to creating that one successful company is about trials and errors. "Learning doesn't happen from failure itself but rather from analyzing the failure, making a change, and then trying again." Don't be afraid to fail early and fail often, until you hit the nail right on the head. One thing I didn't understand from looking at your project is, why did you feel the need to get funding to begin with? It doesn't cost much to keep a website alive, and you have the support of your wife in order to continue developing for Notifo or a new project. I'm also a co-founder myself, so I'd like to know if there's something I'm missing here. :) Another thing I'm curious about is, why you're so set on sticking with Notifo, instead of moving on with a new idea? Is it because you already have tons of users and you need money to expand your company? I've only been involved with one website and I'm still learning, so it'd be great to learn more insights so I know what to expect ahead of time. :)

Wow, your catharsis really comes through in your writing. If nothing else, maybe there's a memoir in all this ;) Seriously though, stay positive and stay in the habit of asking people for help when you're stuck. And don't just ask investors, 'cause their agenda might force them to say 'double or nothing' every time. Ask friends, other tech people, people who work on FOSS, old college professors, online friends. You need to develop, but you also need to spend a lot of time in front of other people. Also, make sure you're doing something you like. If the work is not rewarding, find something that is.

This post is one long moan. Of course startups are hard. So is marriage, and so is jogging. So if you're doing it, you'd better love it, because if you don't, you're going to be miserable. You do it because you love building things and love to learn things -- and you can handle failure, whether it's temporary or permanent. You can recognize that you have not actually failed if you've learned in the process, made personal connections, etc.

People doing startups need encouragement. They may need to be warned that this isn't easy, but they really don't need moans.

I wasn't entirely sold on the splitting up of attributes and properties at first. After all, a big part of jQuery is adding convenience, and this does remove a certain amount of convenience at the end of the day, even if only a little. Then I got to the performance graphs at the end. Those are some impressive speed ups for almost all the browsers (1). The speed + more logical separation seems totally worth it.

simonhamp 5 days ago 1 reply      
I love how fast jQuery is progressing, but it does seem that ultimately the separations of various disciplines (particularly this .attr() and .prop() debate) is a step away from the convenience of jQuery-past.

It's understandable though, because helpers and abstractions add bloat and latency to interactions with the various DOM interfaces. And this latency is the price we have to pay for the benefits these abstractions give us - which include a unified interface to the DOM of many browsers.

The balance of speed vs convenience is very difficult for frameworks like jQuery looking to work for as many people as possible... if you want the convenience at the sacrifice of speed or conversely prefer the speed to the convenience you have one option: build a library specific to your app or your needs.

The rest of us will use jQuery ;)

I had this insight in Junior High - testing friction by putting blocks on top of other blocks, or in a block train, and using a 'force meter' to see how hard I had to pull. The 'force meter' was a piece of spring steel stuck into another block, with a hook on the end.

It was totally non-linear on every surface I tested. The book said it was supposed to be linear. The students were all furtively fudging it, and eventually the teacher said something like "well, its supposed to be linear so do the best you can".

Insight: this was all a bunch of crap. Turns out that friction is totally non-linear anyway, for most materials, but I didn't read that until 20 years later.

He's so totally right about the hand waving approximations used in solid state physics.

All fields of physics need to use some approximations, but those in the solid state were usually the ones with the worst reasons, just things like "it works if we do that" or even "it doesn't if we don't do this".

It went on like that in three courses (two on solid state physics, one on electronics).

Only after that did I happen to come across a decent book which explained some of the approximations in a way that didn't make me cringe, and some of the stuff started to make sense in retrospect. Others are still a mystery to me, and probably always will be.

I sympathize with the horrible equipment. While getting a physics degree, I had a lab where we measured resistivity. My team was the last to succeed in getting numerical data from the 20-year-old oscilloscope via floppy disk. The students scheduled after us had to take a digital photograph of the oscilloscope screen and reconstruct the data from that.

Broken equipment is not confined to undergraduate classes. A few terms later, I had to use the digital photograph method to get data from a spectrometer in a research lab. If my analysis had succeeded, we would likely have published, and the professor would have had a chance at tenure, all on the strength of data obtained by counting pixels.

This "lab report" always brings back good memories because it indirectly launched my career in the game industry. I was finishing up my CS degree at UW Madison and working in Mike Gleicher's computer graphics lab in Spring '02. I had previously met Lucas through a fellow CS student (Alex Mohr, now at Pixar). At some point, Lucas was contacted by the AI programmer at Ensemble Studios (Mike Kidd). Mike, a UW alum, had seen the Germanium treatise and wanted Lucas to apply at ES. A month later, knowing how eager I was to join the game industry, Lucas mentioned Mike's email to me and forwarded him my info. Long story short, I got an interview at ES and was hired straight out of college into a dream job.

The way I have always approached labs is a thorough report on my procedure, complete results (totally wrong or not) and an analysis of Whether I got good results, Why I got the wrong results, How might one improve the experiment to get better result...

That has always served me well. I don't usually get A+'s on lab reports, but I think that's my fault and for an unrelated reason.

It certainly seems to me reflection on what was done and thoughtful analysis on why it was good/how it could be fixed (with specific statements or suggestions, not general ones)/what went wrong demonstrates understanding of the material that simple results do not. I guess if you are being trained primarily to be a lab worker who's job is to produce accurate numbers, that's important, but if the labs are for learning...

During my physics practicals for my high school final exam, I had to measure the voltage of a Daniel Cell using a Dry Cell (1.5V), a 2metre length of wire and a bunch of other stuff.

The only problem... the dry cell was dead, so only carried 0.8V or something. So, my results consistently showed that the Daniel Cell had a PD of 1.7V (it's supposed to be ~1.1V).

The examiner came up with a brilliant solution to "fix" my data. Switch the labels on the data columns.

Loved Tom's social hack for finding cofounders, from Startups Open Sourced. He also has a really good outlook on the role of design in startups.

Q: So, the best way to get to know somebody is to go drink with them?

A: That is absolutely the best way to really get to know a person and what they really like and are interested in because if they are interested in technology, then they will have no problem geeking out with you about Ruby or Node or something for three hours, over drinks; that's when you know that you found someone that could be a really successful cofounder. I think there really is something to doing business in bars. In the early days when there were four of us"we had hired Scott Chacon"we would go to this bar called O'Reilly's, up in North beach. We went there almost every week and that's where we would talk about what we had done. This is after we had started full time and it was where all the decisions were made. A couple of drinks in, you start to just say what you mean instead of thinking so much about whose feelings you are going to hurt or whatever, you say things very bluntly, like, “I think we should do this, and I think you are wrong for saying we should do it a different way,” and now you can have an honest argument about what needs to get done and what the concerns are about the company or how it's structured or how the stock is going to be split. All this stuff will come up over drinks and as long as you are not too drunk, it can be helpful.

Very nice read. That also leads me to mention that Github, as good as it is in 'social' coding or whatever that means,
does not fill a gap for a proper resource on how to use Git. Not that it should and it clearly doesn't carry that mandate, but
there is hefty amount of respect to be made for any group that de-mystifies git in all it's glory.

Hell, there are plenty of comments here, on groups and proggit from users that lose their hair over advanced use of git.

In my opinion advanced consulting services and migration planning for currently SVN,CVS engaged companies would be nice.

You, being a good geek, encrypt your personal systems out the wazzoo.

Then you want to take the next step: encrypted communications (examples: legal, business).

This now makes your request of everyone you deal with to dink with public/private keys and - likely - some sort of infrastructure.

i never understand why we all so easily trust creditcards. i also do it.

a system that basically needs an attacker to just see'n'remember both sides of your card (that you need to keep with you and not is safe) in order be able pay with your money until the card gets disabled or expires.

i noticed in the US people use it to pay by phone, and shops tend to keep that data for convenient repeat purchases.

i need a card for payments online and visits outside europe (especially visits to the US). i'm glad that i have one for those occasions, but i cannot say i think it is a safe system -- it is also constantly under attack.

in the netherlands there's a payment system that most-if-not-all webshops are subscribing to. it redirect you from the shop to the internet banking app of your own bank, there you pay (with some 2-factor kind of authentication), after which you're redirected back. i cannot help feeling a lot safer. :)

From the Army Times article:

That crash landing might have been caused by a phenomenon known as “settling with power,” which occurs when a helicopter descends too quickly because its rotors cannot get the lift required from the turbulent air of their own downwash. “It's hard to settle with power in a Black Hawk, but then again, if they were using one of these [low-observable helicopters], working at max gross weight, it's certainly plausible that they could have because they would have been flying so heavy,” the retired special operations aviator said, noting that low-observable modifications added “several hundred pounds” to the weight of the MH-60, which already weighs about 500 to 1000 pounds more than a regular UH-60 Black Hawk.

How many helicopters and of what kind would it take to evacuate 22 people/bodies plus the SEALs and pilots? Certainly more than a single remaining Blackhawk.

I wonder if the inadvertent tweeter might have been hearing the support copters coming in after the initial raid to pick up the prisoners/crew and that the explosions were also after the fact--the post-raid destruction of the downed helicopter.

I suspect that as the story is progressively refined, we'll learn that rather than being a flawless triumph, the actual reason for success was the depth of backup planning and redundant systems.

This will be ultimately be a story that becomes a lesson in how the military learns from its failures (Operation Eagle Claw: http://en.wikipedia.org/wiki/Operation_Eagle_Claw and the Rattle of Mogadishu aka Black Hawk Down: http://en.wikipedia.org/wiki/Battle_of_Mogadishu_(1993)) rather than from its successes.

Very nice, but the analysis seems to assume that HN rank is determined by the headline and not by the content. (More precisely: for the analysis to give useful guidance to would-be HN headline writers, it needs not to be the case that content features correlated with headline features make a big difference to HN rank.)

My proposal for a good headline according to the numbers in this article: Showing why impossible future controversy survived the problem could hire data. Score: 1.3 (could) + 1.2 (problem) + 1.3 (survived the) + 1.0 (controversy) + 0.9 (impossible) + 0.7 (why ___ future) - 3.3 (11 words) + 2.6 (showing) + 0.5 (hire) + 1.9 (data [END]) = 8.1. For comparison, Why showing the future is essential to acquiring data gets 1.4 (essential) + 0.7 (why ___ future) - 2.7 (9 words) + 2.6 (showing) + 1.7 (acquiring) + 1.9 (data) = 5.6 -- except that it doesn't really get the points for "essential" (not at start) or "why ___ future" (two words in between) or "acquiring" (not in second place, word isn't quite right). Of course my headline has the little drawback of being total nonsense.

It's always exciting to bump into, meet or find out about someone who can see interesting possibilities where others see nothing. I don't know Joe, but he seems like one of those people (Firebug, FTW!).

At the same time, I'm always kind of bummed when those people are snapped up by a large company because their ability to produce the mind-binding ideas seems diminished or, at least, less visible among the many large accomplishments/events of a large company. Good to see that one of the lateral thinkers is returning to where we can more easily see his ideas in practice.

Firebug: I remember the first time I left behind the edit-save-refresh-cry-because-my-padding-was-wrong cycle of HTML/CSS development for the Firebug-driven-tweaks flow. Excellent.

It sometimes seems it's difficult to make money from making tools, because developers expect them for free, and with source (like Firebug). But of course it is possible, with products like Joel's FogBugz, like Jira and some IDE's.

Apple not providing LGPL webkit source code for latest iOS 4.3.x gnumonks.org

For iOS 4.1, which came out in September 2010, absolutely no GPL code for it (or later versions, like 4.2) was posted until March 2011. That's not 8 weeks: that's about 6 months.

When comex (http://twitter.com/comex) and saurik (http://saurik.com/) asked for it (via emails to opensource@apple.com and copyright@apple.con) around last November, I don't think they got any response from Apple "until this year. Then, Apple let them know that it would be up "within a week". I think the iOS 4.1 and 4.2 code actually went up about three weeks after they received that email.

saurik has even more examples of them not releasing the [L]GPL'd code near the top of this post: http://www.saurik.com/id/4 " "Frankly, I wouldn't be surprised at all if Apple ends up on the bad end of a GPL-related lawsuit."

(In my opinion, the fact Apple has posted any code for iOS 4.3 at this point is a big step in the right direction: they're not perfect yet, but at least they've got 8/10 of the projects up.)

Apple, as with many other companies, does not understand that it has to release the source simultaneously with the program using it.

The only clause I can see Apple potentially hiding under is Section 3.B of the GPL.
ie. as long as they have the door open for written requests all is well.

Shocking but true. When I read my grandparents diary about the Spanish civil war(1936), I see they killed people for getting info about the relationships, friendships of the principal leaders so they could kill selected people and destroy entire public movements.

That happened in WWII too. When Soviet Russia entered Poland, the first thing they did was to investigate the links of relationships of the Polish resistance. They kill every single of them so nobody opposed the Soviets(if they opposed German domination they would oppose Soviet too).

That was not far ago. Today a single American company could store all your public information, and your messages(audio transcribing is starting to work) because you give them.

Facebook is great as a concept, but It would be a better idea using private implementations with your own servers not depending on a commercial company. Something simple to use with open communications...

Never let yourself, your loved ones, family and friends be cataloged by any company other than the mandatory government citizen list.

Call me paranoid, but there is absolutely no reason for a social network at all. Social engagement and links, and poking and other shit is not a benefit to me. It's not a benefit to people even though they like to pretend it is.

In return for handing over all that information you have gained a monitored, controlled, censored and limited way of communicating. There is a reason why speech is protected. Why put a secondary layer of control on how you choose to express yourself.

Taking a page out of a way-back-machine, making links between people for complete eradication of opposition during WWII, was key in killing off most of noble and intelligent opposition in Poland.

I believe that the benefits of a social network such as Facebook outweigh the risks. The problem is that, it is very hard to quantify the positive effect which arises from small interactions. Sure there is huge scope for improvement, but one could have made similar arguments against telephony when it was invented.

I believe we are still to see rise of real social network based applications. e.g. something that allows us to estimate trust for a person, given his and your social network.

Assange's claim that Facebook and the other myriad social tool's he mentioned are spy tools is a bit embellished. He's right in that U.S. intelligence agencies can and will gain access to the data stored by these services (if necessary). However, saying that it's inherently a spy tool just seems a bit on the Salem side. If there's information about us or our lives that we deem sensitive, the last place you want to put it is online. There's noted security flaws in pretty much every system out there and to dismiss that reality is a bit naive.

There's most definitely a problem with security in this era, but it's important to note that we're the one's doing it. Honestly, anyone who may expose sensitive information should have Facebook or any other online presence on the top of their list as things NOT to use. When you're being nefarious communication is a bit difficult, eh?

I am pretty sure something similar to this exists now. The new threat to america are not from soverign nation states, but from non state actors. Solving the data fragmentation problem by combining sources of personal information about behavior and life will make it easier for the gov to stop attacks or catch a person. Combining sources like your facebook, financial transactions, credit card bills, websites you visit (by using facebook connect), travel history (past plane tickets that are linked to your credit cards) can all be combined together and a predictive analytical tool can be developed for automated red flag for things that are deemed suspicious.

Facebook can do the same thing but use the information to predict who you are as a consumer, who you influence, how popular you are, etc to deliver targeted ads, etc.

Although it's a bit of an apple to oranges comparison Copenhagen suborbitals are on the trajectory to launching a human into space in around three years time. In a months time they'll have their first testflight from Bornholm in the baltic sea. They're doing this whole thing based on nothing but sponsors and goodwill. Their budget is around $8000 a month - orders of magnitude lower than spacex. They also built the worlds largest homemade submarine btw.

Until now they've developed solid rocket boosters, parachutes, recovery programs, astrouanut survival and cockpit, etc. etc. and have not run into major problems yet.

People will probably vote not to launch anything, not to look at the sky, but to spend money on land issues instead. My big concern is regarding the end of the dollar as the world's reserve currency. That could bring many succesfull companies down, specially those on American markets only. China can be a big issue to America if it starts no to believe in dollar currency anymore.

A couple of additional points about my abysmal 8/8 failure rate:

  - These were in 8 different machines in 8 different locations.
- 7 were in desktops, 1 was a laptop
- All were running Windows
- All purchased from NewEgg
- Most of these were gifts for other people.

(I may be slightly crazy, but I don't have 8 computers.)

After this saga, I've concluded that there are probably two root causes leading to high failure rates:

(1) Something about installing an after-market SSD in a desktop, probably related to power fluctuations, increases the likelihood of failure.

(2) NewEgg only offers a 30-day warranty on their SSDs. You can't even purchase a third-party extended warranty. So I suspect that you'll see a higher failure rate from NewEgg purchases than from a merchant who offers a 2- or 3-year warranty. (But NewEgg's prices are so damn good!)

I should also say that the SSDs that I have purchased with laptops - 2 from Dell (2008, 2009) and 1 from IBM (2009) have not failed.

Read this if you are concerned about TRIM and want to restore a SSD drive on OS X to a "new" state.

If you have an SSD on OS X, I discovered that in many cases you can "reset" the drive and regain performance. Basically, if your drive implements the "security erase" command, you can use the following procedure by taking the cover off the back of your Macbook, removing the hard drive, leaving the SATA cable in reach, and booting with the GParted Live CD.

http://www.ocztechnologyforum.com/forum/showthread.php?76612...

The tricky part: You have to plug in the SSD drive >after< your machine boots, so it's not in "frozen" state. The other tricky part, is that you first have to set a security password to do the erase. Then doing the secure erase also erases the password.

I know first-hand that this works on Crucial C300 RealSSD and I've seen lots of reports that this works with OCZ drives. This is also useful for doing new installs on an SSD if you've gotten a new machine. (My situation)

WARNING: DO NOT try to use a Crucial C300 SSD with an i5 or i7 2011 13" Macbook Pro. The problem is in the hardware, namely electromagnetic interference in the SATA cable when trying to use 6GB/s SATA. Wrapping it with aluminum foil doesn't always work. Buying an upgraded SATA cable doesn't always work either. Buying a 2010 Macbook Pro instead always works. You have been warned.

I wonder how well the SMART stats would predict that failure -- or whether they were sudden unexplained failures.

If you run smartctl -A on your SDD device then for e.g. Intel you can see attribute 0xE9 or 233 -- media wear indicator, starting at 100% (mine's at 98% after 14 months, so this should hopefully indicate 2% of the wear out from writes). You can also see how many of the reserved blocks it's used (when it fails to reflash a cell when rewriting).

To be recorded the VAS had to be made directly through the merchant, which is not always the case since it is possible to return directly from the manufacturer: however, this represents a minority in the first year.

- Maxtor 1.04% (against 1.73%)
- Western Digital 1.45% (against 0.99%)
- Seagate 2.13% (against 2.58%)
- Samsung 2.47% (against 1.93%)
- Hitachi 3.39% (against 0.92%)

Hitachi is plummeting, which was first in the previous ranking! Western Digital retained its second place despite a failure rate increasing, while Maxtor is occupying the first place.

More specifically the failure rate for 1TB drives:

- 5.76% Hitachi Deskstar 7K1000.B
- 5.20% Hitachi Deskstar 7K1000.C
- 3.68% Seagate Barracuda 7200.11
- 3.37%: Samsung SpinPoint F1
- 2.51% Seagate Barracuda 7200.12
- 2.37%: WD Caviar Green WD10EARS
- 2.10% Seagate Barracuda LP
- 1.57%: Samsung SpinPoint F3
- 1.55%: WD Caviar Green WD10EADS
- 1.35%: WD Caviar Black WD1001FALS
- 1.24%: Maxtor DiamondMax 23

Hitachi is logically the less well placed, what with two separate lines! What about the 2 TB version?

- 9.71%: WD Caviar Black WD2001FASS
- 6.87% Hitachi Deskstar 7K2000
- 4.83%: WD Caviar Green WD20EARS
- 4.35% Seagate Barracuda LP
- 4.17%: Samsung EcoGreen F3
- 2.90%: WD Caviar Green WD20EADS

Overall, failure rates recorded are bad. That does not really want to entrust to 2TB of data to these discs alone: a mirroring will not be too much for securing data. Logically 7200 rpm disks are less reliable than the 5400/5900 rpm, with almost 10% for the Western model!

For the first time, we also integrate SSDs in this article type. The rates of failure recorded by manufacturer:

- Intel 0.59%
- Corsair 2.17%
- Crucial 2.25%
- Kingston 2.39%
- OCZ 2.93%

Intel stands here with a failure rate of the most flattering. Among the few models sold over 100 copies, displays a rate of no more than 5% VAS.

I also thought that about SSDs.

Then I stumbled upon this on the Apple store when configuring your disk options: "Your MacBook Pro comes standard with a 5400-rpm Serial ATA hard drive. Or you can choose a solid-state drive that offers enhanced durability."

So, why do they say that? What SSD do they built in? Is that a particular special SSD with enhanced durability? Even more enhanced than regular harddisks (like they are claiming)?

I've often wondered about this stuff. MLC SSDs are good for 10000 writes per 250k (iirc?) block. When you think about using an SSD for virtual memory, even with wear levelling, that's really not very much at all. Add in programs that do lots of small file writes to logs and so on, and I can imagine losing a lot of blocks fairly quickly - particularly because wear levelling will cause you to lose all of the blocks in a relatively small time space, as opposed to gradual failure.

I wonder if, as flash memory gets cheaper, we'll see SLC SSDs getting more popular.

One of the cool things about SSDs will be the huge amount of random I/O we can throw at them without noticeable responsiveness slowdown. SSDs will probably increase peoples' desire to backup because it will no longer be such a drain on I/O responsiveness.

I must be remarkable lucky. I have seven SSDs, four of them are installed in computers I use often, and some more in datacenter servers. I have never had a failure. And the SSD that's in my home unix server is already doing its job for almost two years now.

I do make regular (image) backups from all my SSDs, so when one fails I can quickly replace it and restore the image. Apart from that I keep all my sourcecode and work-related stuff in a source code versioning control system hosted in a datacenter.

My first SSD died in three days. It is entertaining when an SSD dies, as you simply get a "no OS found" type error from your bios. Checked the drive and it appeared to be working, only was completely empty.

Swapped it out, been fine since (about a year and a half now). Also no problems in my mac.

But both machines run regular backups so that should an SSD fail, it's just a matter of imaging the new drive and replacing it.

I have been using an enterprise-class Intel SSD (X25-E I think) for about one year now in my workstation so help speeding up the build/linking process of a large C++ project. This has made all the difference in development speed for me. The disk gets punished a lot, lots of file copies and read/write operations. To date I haven't had any problems (nor have I heard of any from colleagues who are using them in the same way). I wouldn't care much about data loss though since only temporary files are on there.

My experience on SSDs, having used multiple drives myself and sold 100s of drives to tech savvy customers:

- Brand does matter - the failure rate on Intel drives is a lot lower than other brands.

- The system you put it in also makes a difference. For example, certain generations of Macbook Pros are just not happy with certain SSDs. We've had customer that had two or three failures with a certain brand / model / chipset, and then changing to a different SSD they haven't had problems.

- The failure rate for SSDs overall is higher than that for HDDs, but lower than the failure rate for some other products (such as Graphics cards).

- Every SSD we have sold went into a custom built system or was installed afterwards into a laptop, so I don't buy the argument that problems are caused because it's installed by an end user and not at the factory.

- They are blindingly fast. In my opinion, it's better for 90% of users to put a new Intel SSD into their existing system, than it is to buy a new system.

Would it be possible to process the images somehow and find the noise profile for every image and match it with existing images?

When I found a directory full of images and couldn't remember which camera took them, I noticed that there were a few fuzzy pixels of green and red if I zoomed all the way in that were present in all photos taken by that camera. I took a photo of a white wall in a dark room (to force high ISO) with a couple of my cameras and found the one. Of course I found out about the EXIF serial number and other unique data later on, but it could still be useful on sites that store the original image but strip EXIF.

charlief 3 days ago 3 replies      
Good idea, but works most effectively when:

(1) Various encode/decode steps along to publishing the photo online don't corrupt EXIF data

(2) Thief isn't sophisticated to wipe/disable EXIF data. Many cameras shoot in a proprietary, higher-bit format and give you a fairly obvious wizard option on a desktop tool to include/exclude the EXIF data.

(3) Thief will use the camera, not sell it immediately into a second-hand market.

(4) Even if your camera is supported, it has to be configured to record EXIF data by both you and the thief. Some proprietary formats are fairly raw and don't always include EXIF-derivable data by default.

This will get some adoption because what other option do users have, but it will be interesting to see how many uploads convert to a lost camera being recovered/thief being apprehended. If users had the ability to leave a testimonial when there is some kind of closure, you could derive a metric of success.

For my other camera, a Pentax K20D which is on the supported list I got:

"Problem extracting serial number. If possible, use an original image from the camera that has not been edited in any software."

The only thing I had done was uploaded the image from the camera via iPhoto. But all the EXIF data was in tact, including the Pentax K20D, the serial #, even the lens I used. So I don't think iPhoto stripped any data.

I'm wondering why if Flickr for example can extract all of the EXIF data, even for images not directly from the flash card, why did this happen?

The photo itself is not uploaded to the site for checking. Only a few bytes with the serial and camera model/manufacturer are sent in a HTTP GET to stolencamerafinder.com. This makes it very light in traffic.

The site can expand the camera->owner database by searching photos with valid EXIFs on famous sites and correlating it to the user.

The project is a great proof of concept, the chances this will get someone's stolen camera back is pretty slim. We have a similar project, but it searches for the data using existing search engine data. Only about 25% of cameras will embed the serial number, then when uploaded only a few sites will retain the EXIF data, or provide it through meta data. A few that keep the EXIF data or provide it in meta data include:

Flickr.com
DeviantArt.com
SmugMug.com
Picasa.com

Some of these sites strip out some tags. Some manufacturers have custom EXIF tags like Nikon which may store the serial in a "Serial Number" tag or a tag called "0x00D".

So, I assume that there's no way to tell whether a photon was emitted by antimatter or by matter.

Therefore, how do we know distant galaxies aren't made of antimatter ?

Maybe there's an obvious answer, but as far as I know, the only thing we can know about these galaxies, we know because of the radiation they emit.

From the "Completeness of Quantum Theory" chapter (on one theory of the determinability of quantum systems): "If an atom has a probability of one half of radioactive decay over an hour, then all that really means is that its wave function describes an ensemble of many different atomic systems, half of which decay in an hour. Whether one particular atom in the ensemble will decay in one hour is definitely determinable. However we will not be able to discern it if all we know is the quantum wave associated with it. Whether it decays or not depends upon properties of that system that have been smoothed away by the quantum wave and thus are unknown to us. It is our ignorance of these smoothed away properties that makes a probabilistic assertion the best we can do."

HN, what does "Whether it decays or not depends upon properties of that system that have been smoothed away by the quantum wave" mean?! What properties exactly, and smoothed away how? Just by the fact that observing the system causes a change within the system and therefore changes the quantum waves?

Thanks for taking the time to share this, bluesmoon. It's an excellent counterpoint with a broader perspective than my post.

I've learned a lot about this over the past couple of days just from the comments here, on Twitter, and on my blog.

A lot of it has been just learning not to lump all of "open source" into one big scary thing, but to find the smallest unit of work you're capable of doing, and to find a project with a supportive team who will be patient with you.

I think you are owed some of the credit for this story, as George found a project where his contributions are valued and the maintainers were patient with him.

For me, so far, this has been BDSM with Wayne E. Seguin, who goes WAY above and beyond to nurture this kind of environment for his projects and encourage contribution.

Thanks for sharing this. I think open source would have a lot more activity if newbies like me had George's persistence and maintainers had your patience.

Having all inet services running over port 80 and TCP does not make the net any safer or better. We as hackers should fight for making people aware of and remove such restrictions, not accept and worsen the crippled situation by working around the problem. This is one of the key problems in the digital world today, too few actually makes an effort to fix the underlying problems. Here Google could play a crucial role, and I must say that I am dissapointed by their choice.

It's a good improvement over HTTP 1.1 and it's nice how they did it in a completely transparent way. Now it's time for the other browsers to support it and to implement way to hint the usage of spdy (maybe a <link rel="" in the first HTTP request, or an extra header in the HTTP request).
