> Ultimately I was hoping that antirez and other contributors might realize why their proposal for a custom replication protocol was unsafe nine months ago, and abandon it in favor of an established algorithm with a formal model and a peer-reviewed proof, but that hasnt happened yet. Redis continues to accrete homegrown consensus and replication algorithms without even a cursory nod to formal analysis.

That is kind of my feel. Redis is an outstanding product with a beautiful code base. This replication feature has been tough though. It is kind of due to external factors as I've mentioned in the previous post. Everyone and their cousin are talking about distributed databases, everyone likes CAP, CRDTs, Vector Clocks, Raft, Zookeeper and so on. It is hard to come up and say "Here I have made this custom replication protocol". Everyone stares and asks, "Hey where is your whitepaper or your partition tolerance tests?". 5-7 years ago, there would be only nods and approvals. The other aspect is this is about a database, so it is potentially toying and touching user's valuable data. If that gets lost either by a bug, mis-communication in docs, bad default, anything, it will not be taken lightly.

In the end I think it is fine to have it as what it is, with the warnings and disclaimers that data could be lost and avoiding papering over or hiding issues.

As an extra side note, simply put partition tolerance is hard. Net-splits are the devil of the distributed world. Some claim it doesn't exist or doesn't happens often. Others fear and tremble its name is mentioned. When it does happen it means having to resolve conflicts, throwing away user data, stopping killing your availability to stop some from accepting writes in order to provide consistency. This is a tough test (that Aphyr runs) and not very many databases fair well in it. But it is good these things are discussed.

A person who found themselves sympathetic to the kind of hand-wavey feel-good explanation of things in yesterday's Redis thread might find this conclusion kind of snotty:

> I wholeheartedly encourage antirez, myself, and every other distributed systems engineer: keep writing code, building features, solving problemsbut please, please, use existing algorithms, or learn how to write a proof.

That person should be sure to note these experimental results:

> These results are catastrophic. In a partition which lasted for roughly 45% of the test, 45% of acknowledged writes were thrown away. To add insult to injury, Redis preserved all the failed writes in place of the successful ones.

It feels like we're just about at the tipping point with cannabis. Once enough states in the US legalize it, the Feds will have to back down.

The next step will be for people to wake up to the fact that harder drugs need to be legal too. Not so that more people can take them, but so we can have less crime and eliminate a key justification for the growing police state.

Until today, the only places in the world where marijuana was legal are two states in the US (Colorado and Washington)[0], and the entire country of North Korea[1].

Other jurisdictions have decriminalized marijuana, but most of us haven't seen the legal sale of recreational marijuana in our lifetimes (in the US, it was all-but-illegal since 1937, and truly illegal since 1970 - there were only 6 months in 1969 during which there were technically no laws prohibiting its sale).

These are exciting times we live in.

[0] Technically these haven't gone into effect yet, but I'm still counting them.

[1] Surprising, but (as far as we can tell) true. Less surprising when you consider that exports of drugs that need to be engineered (like methamphetamine) are one of North Korea's biggest sources of foreign currency.

Legal drugs != less crime...

On one hand, yeah sure, some people won't end up in jail for buying/selling/consuming drugs but those are just like little drops in the sea.

The sea is actually the major criminal organizations that are perpetually conflicting with each other in order to maximize their particular profits. A situation where the demand becomes bigger (because it's not illegal anymore) will only put more fuel onto their war.

And yeah, you would say 'it was the same way with alcohol'; NO it wasn't. That was a problem of a very different society at a very different time; to put that on perspective: when have you heard of ENTIRE countries employing practically everyone (even children) to grow, launder and even murder for the business?

I'm all for legalization, but my concern would be that now gangs will grow pot in Uruguay to export to neighboring countries. This may spark turf wars and the like...

Given the limits on how much you can buy at have, hopefully they can still tackle large operations

EDIT: Let me expand, because I think people are missing the point. There are drug gangs in the region that grow pot. After this law comes in to effect it suddenly becomes easier to do business in Uruguay. Wouldn't that be an incentive to move shop to Uruguay? It seems like if all the local countries don't sign up, then you're signing yourself up for trouble.

NSA uses Google cookies to pinpoint targets for hacking washingtonpost.com

There are two primary issues here: the prevalence of Google Analytics and the unencrypted nature of the majority of websites.

Google Analytics is on a substantial proportion of the Internet. 65% of the top 10k sites, 63.9% of the top 100k, and 50.5% of the top million[1]. My own partial results from a research project I'm doing using Common Crawl estimates approximately 39.7% of the 535 million pages processed so far have GA on them[2].

That means that you're basically either on a site that has Google Analytics or you've likely just left one that did.

If the page you're on has Google Analytics and isn't encrypted, the Javascript request and response is in the clear. That JS request to GA also has your referrer in it, in the clear.

The aim of my research project is to end with understanding what proportion of links either start or end in a page with Google Analytics. If it starts with Google Analytics, your present "location" is known. If the link ends with Google Analytics, but doesn't start with it, then when you reach that end page, the referrer sent to GA in the clear will state where you came from.All of this is then tied to your identity.

If people are interested when I get the results of my research, ping me. I'll also write it up and submit it to HN as it would seem to be of interest.

Where do you draw the line so that organizations like Google do not handover (willingly or inadvertently) our life to NSA, GCHQ, ASIO, CSIS & whatever New Zealand's Intelligence spooks go by, on a platter?

The function try blocks is new to me. It's actually kind of elegant (for C++). Granted, the reason I've probably never encountered it in the wild is that there are probably very few scenarios where you have a member in the initializer list where you want to handle an exception on initialization. If you were trying to handle an exception of an instance variable initializing, most people would just move that member to the constructor body (e.g., if you have a pointer). The only time this would be useful then is for members that don't have default initializers (e.g., a reference).

An Engineers guide to Stock Options alexmaccaw.com

grellas 10 hours ago 7 replies      
Really nice write-up explaining stock options. A few added thoughts sparked by some of the comments already made in this thread and otherwise:

1. The value of options is inextricably linked to tax and you need to understand the tax basics in evaluating the economic risks and benefits of holding and exercising any kind of option. With NQOs, you are taxed on the spread as ordinary income on the date of exercise (meaning, on the difference between what the stock is worth and what you pay to exercise). With ISOs, the value of the spread becomes subject to AMT and you can wind up paying large taxes that way in spite of the supposed tax benefits of ISOs. The way to avoid having a large spread subjecting you to such tax risks is to exercise as early as possible before the company value goes up much but you then need to take the economic risk associated with having to pay hard cash for stock whose long-term value is highly uncertain. Moreover, early exercise is not possible if your options haven't vested unless you specifically get an early exercise privilege as part of your grant. With an early exercise privilege, and particularly if the grant is made for a bargain price, you can early-exercise, file an 83(b), and (as long as you hold the stock for at least 2 years) get the equivalent of a restricted stock grant by which you pay no further tax until you eventually sell the stock at a liquidation event. In that case, you are also taxed at the lower long-term capital gains rates. Of course, in the early-exercise scenario, you do not get to bypass vesting and your shares remain subject to their original vesting requirements and can thus be forfeited in whole or in part if those requirements are not met. But early exercise does provide an elegant solution to most of the tax risks associated with options provided you are willing to assume the economic risks of paying for the stock up front.

2. Other than the early-exercise scenario, 83(b) elections are not required for option grants. Under 83(a) of the Internal Revenue Code, any service provider who gets property in exchange for services is taxed at ordinary income rates on the value of the property received. For example, if you do work for a startup and are paid in stock when you complete the deliverable, you are taxed on the value of the stock received. You are taxed on the value of that stock as it exists as of the date you receive it in payment for such services. So, if you do development work tied to a milestone, and you meet that milestone, and you get 100,000 shares for the work, you would be taxed on, say, the $1.00/sh that the stock is worth on the day six months or a year (or whatever) out when the milestone is met, and not on the $.01/sh that it was worth when the contract terms began. In contrast to this performance-based form of incentive, let us say that you get a time-based incentive by which you buy the stock up front for a nominal price but you must earn it out over time. With such a time-based performance incentive, which is what is called "restricted stock", you own the stock up front and you pay no tax at the time of purchase in the normal case where the amount you pay for it equals its fair value on the date of the grant. Because the stock must be earned out as part of a continuing service relationship, and is hence subject to a "substantial risk of forfeiture", there is a very important technical question under section 83(a) on what the date is on which you are deemed to have received the stock in exchange for your services. Well, the default rule under 83(a) is that you receive it on the date it is no longer subject to a substantial risk of forfeiture and that then becomes the relevant date on which the value of the stock is measured for purpose of computing the taxable service income on which you must pay tax. So, if you get your 100,000 share grant at $.01/sh, and you pay $.01 share, you pay no tax at inception. But, as that grant vests at, say, a monthly ratable rate over four years, the IRS treats you as having received 48 separate grants (one each month) over the four-year period. Thus, at each vesting point, you are treated as having received property in exchange for services under 83(a) and you pay tax on the difference between the value of the property received and what you paid for it. If you paid $.01 per share, and if the stock is worth $1.00 at a given vesting point, you realize $.99 worth of taxable income per share. In a venture whose value is rising quickly, in the absence of any saving mechanism, you might have as many as 48 separate tax hits (basically, having to pay tax on the difference between what you paid for your grant and the 409A valuation price placed on the common) just for the privilege of holding a piece of paper that may or may not ever have an ultimate cash value of any type. It is in this type of scenario, and only here, that 83(b) comes into play by providing that, in lieu of having to suffer under the default rule of 83(a), you can elect to pay all taxes up front on the grant and not be subjected to the often onerous workings of the default rule. This means that, for an 83(b) election even to be relevant, you must first own your stock (or other property) and that stock or property must be subject to a substantial risk of forfeiture. If you hold only an unexercised option, you do not yet own the stock and it is not subject to forfeiture (hence, 83(b) is not relevant). If you do an early exercise, though, and get stock under terms where it must still vest out and can be forfeited, then 83(b) does apply. But that is the only case normally where it becomes relevant at all to options.

3. Options really shine when they wind up on a level playing field with the preferred stock and they tend to dim commensurately to the extent they do not. Optimum case is IPO when all stock is (typically) forced to convert to common prior to the public offering and, thus, all shares participate equally in the benefits. This can happen too in big-scale M&A exits but a drop-off occurs on lesser ones in at least two ways: (a) where the total acquisition price is largely gobbled up by the liquidation preferences and/or management incentive plans; (b) where an acqui-hire occurs in which a few founders get a disproportionate share of the total value through employment arrangements made on the other side of the deal.

4. Given all of the above, and given that IPOs remain at far below the old bubble levels in frequency, it can be risky to lay out any excessive cash to exercise at any time before a liquidity event. Too many things can happen by which a seeming "sure thing" winds up evaporating before your very eyes, leaving you with no more than a pretty lousy capital loss that you get the privilege of deducting at the rate of no more than $3,000 per year unless you can find other capital gains to offset it against.

5. The 90-day tail for exercise upon termination of a service relationship applies only to ISOs and not to NQOs but, of course, ISOs have other advantages and they are what is typically offered in VC-backed ventures. In other types of ventures, where the company value is already somewhat high at the time of grant, I have seen executives bargain for and get NQOs with long exercise periods following termination just to have the flexibility to leave the venture if needed without being forced to forfeit the options.

6. In light of all of the above, having to pay an angel backer 25 or 30% of your gains to provide you with a risk-free exercise in an otherwise high-risk situation may be worth it even though the cost seems high on its face. It is a matter of preserving some decent part of your potential upside while giving up the rest to make the upside potential even a possibility for you given the tax risks involved. If IPOs come back strong some day, then you may be giving up too much at such a cost because they are the great leveler when it comes to weighing the value of options against other forms of equity holdings. Until that day comes, however, options remain a valuable but relatively high-risk way of deriving value from a startup if you need to part with any significant cash (either for the purchase or for the associate tax) for the privilege of hoping to profit from a startup. Again, for those who need to weigh their choices, this piece provides great insights and stands head and shoulders above the typical discussion of such issues. Great work by the author in making an otherwise dry and even formidable subject pretty accessible.

I've "pre-exercised" before, with a meaning different from what's depicted here in the article.

In the "pre-exercise", I was able to exercise the stock before I'd vested in it, with the understanding, of course, that the company would buy back my unvested shares at the exercise price if I left the company before vesting all the options.

The disadvantage, of course, is that you pay for your stock up front, and will lose all or most of the money if the company doesn't pan out.

There are several advantages ...

Advantage: the price you exercise at is near the fair-market value of the Common Shares you purchase (and haven't yet vested in), so there's no immediate gain and so no immediate short-term gain tax consequences. You need to make sure to file an 83(b) form so you're telling the IRS you're paying your $0 tax up front, rather than monthly as your stock vests. (The disadvantage with the latter is that the difference between what you paid and what your stock is worth as it vests could be huge, and there's no way to liquidate your stock to pay that tax.) (There's also something about AMT in here, I'm kind of fuzzy, but I think consequences can be the same.)

Advantage: your long-term capital gains clock starts ticking the day you buy the stock, even though you bought before any of it vested. When, three years down the road, you can liquidate your stock in that acquisition or IPO or secondary-market sale, you already purchased your stock three years ago, and pay only long-term gains. Otherwise, you'd buy the stock and sell on the same day, with the gains considered as short-term-gains/income rather than long-term gains.

My personal outcome with pre-exercised stock: worked out OK twice, lost all my pre-exercise once, but overall I came out ahead on taxes even with the loss. YMMV.

What the article says is "pre-exercise" is just an "exercise" -- you vested the stock, you have every right to purchase it even though the company's stock isn't yet liquid. The problem, of course, is that you may have a huge gain and no way to pay for taxes on that gain.

(Edit: note about AMT, clarification.)

This is very helpful, thanks. I was very surprised when I first learned that AMT will cause you to owe tax on your gains when exercising options, even if they are only on paper. (If the company is public or there is a private market, fine, but it is incredibly inconvenient to be taxed on something for which there is currently no market). This is an area where it can really pay to plan ahead.

If I decide to leave a company in which I have partially vested stock options, would it be okay to ask my employer (or anyone else in my company) if they would be interested in buying the options off of me at the current valuation (EG, last amount of money raised)? Is something like this common, or would I get laughed out of the room?

Similarly, how liquid are markets like Second Market in terms of liquidating option value at a startup that's raised multiple rounds of funding but has yet to exit or IPO? Are there angels (or networks of angels) that buy small amounts of pre-exit equity?

There's some valuable information here, but a lot of detail is lacking. For instance, the post does not distinguish between incentive stock options (ISOs) and non-qualified stock options. The tax treatment is quite different.

More importantly, technical details aside, I think it's important for a prospective employee to make some strategic decisions about equity up front.

The author writes:

> If the company seems reluctant to answer these questions, keep pressing and dont take no for an answer. If youre going to factor in your options into any compensation considerations, you deserve to know what percentage of the company youre getting, and its value.

And in the next paragraph he writes:

> Id be wary of compromising on salary for shares, unless youre one of the first few employees or founders. Its often a red flag if the founders are willing to give up a large percentage of their company when they could otherwise afford to pay you. Sometimes you can negotiate a tiered offer, and decide what ratio of salary to equity is right for you.

You can't have it both ways. If you focus on equity (by demanding that the company divulge detailed information about its share structure), you are sending the signal that equity is just as important or more important than salary, and thus opening the door to a negotiation that contemplates a trade of equity for salary. Precisely the thing that you want to avoid!

Unless equity is expected to be liquid in the near future (i.e. you're at a company expected to go public in the near future), an equity-focused negotiation is more likely to benefit the prospective employer than employee.

>> You can think of a stock option as a Future.

You probably shouldn't, as they are distinct terms. A futures contract obliges you to make the transaction on the specified transaction date, whereas an option gives you the option to do so.

Two corrections:

1. OP says: Once youve cliffed, you have the right to buy shares in the company.

"Cliffing", when used as a verb, refers to firing someone just before the cliff-- not an employee achieving it. It's something you'd rather avoid.

2. If the company isn't publicly traded, you should ask to see the cap table. If you're employee #30 and your share is 0.05%, that might be fair if it's a biotech that has already taken a $100M infusion from the venture capitalists (who'll typically take 90%, in that case). For a web startup, it's terrible. You need to know how much equity the investors, executives, and employees at various levels have, so you can evaluate your likelihood of getting an improvement if you perform well. Without the cap table, you don't know enough about the startup to decide whether to take a job there.

For the US, joining the deal, and then forcing it to either confirm to US wishes, or breaking it entirely are much, much better options than losing influence in the region.

"According to the report, Nokia plans to fork Android to fit its purposes, similar to the approach used by Amazon."

No, please no !!!

We have the Amazon fork; various Chinese forks; and now a Nokia fork ?!?

I think this damages the Android brand. The way Google has been consolidating functionality into Play Service is a direct move against this kind of thing, whatever they say about open source being good.

Whats the point of this? Samsung is making most of the profits from Android. They dominate the high end Android phones with LG in second if I recall. On the low end, there is a slew of junk but some interesting and very capable devices like the Moto G (as far as I can tell, it could only use a better camera and build quality).

Are they attempting to compete with the Moto G and future Google/Moto devices targeted at this space, presumably as Google lets other OEMs have the high end, using their own fork and ecosystem?

Maybe they should do Plan B with Ubuntu Touch and/or Firefox OS

This is not 2x matching. This is just plain and simple matching. You donate 50, they get a total of 100 - 50 from you, and 50 from the donor.

Yes, the total amount they receive is 2x, but the matched amount is 1x.

I sound pedantic but it's because this is in stark contrast to the Internet Archive's "3x matching" through the end of the month, in which if you donate 50 they receive a total of 200, because the matching amount is triple - 3x - what you donate.

I wish there were more options besides the EFF who supported the myriad of causes the EFF works towards.

Their treatment of CISPA was not, however, something I can stand to support, and for this reason I can't justify giving them money until they soften their hardline stance substantially.

Their "call to arms" press release was rife with doublespeak and inaccurate interpretations of the proposed bill, and it felt like there was some kind of ulterior motive at play for them to never be satisfied with concessions and changes to the bill text.

I get this sense that the EFF basically says, "no!" to every bill coming from congress that has anything at all to do with the Internet, and that's just not a useful way to run an advocacy group.

I support a free and open Internet (seriously, who doesn't around here?) but I would rather codify that in US law than sit around and wait for the FCC to fine Comcast. If congress can't touch the Internet, then they can't protect it, and I'm afraid the EFF would find itself on the wrong side of an open Internet if congress tried.

They took two different universe models, neither of which match the one we live in, and mathematically produced the same black holes. The key differentiators being that one universe has gravity and multiple dimensions while the other has no gravity and 1 single dimension.

While the article likes to take a logical leap and assume this supports the theory that our universe is a hologram, what was actually proved by this numerical experiment is eloquently explained in the article's quoting of theoretical physicist Leonard Susskind.

"They have numerically confirmed, perhaps for the first time, something we were fairly sure had to be true, but was still a conjecture namely that the thermodynamics of certain black holes can be reproduced from a lower-dimensional universe"

I wish people would move beyond 1984 and quote more Foucault's Discipline & Punishment [1]. There is a much deeper-rooted problem in society than mass surveillance or militarization of police. It's the question of why we all let this happen without any resistance. We accept and welcome our controllers. Foucault wrote about the effects of prisoner mindset in society in the 1960-70s. Our subjugation and tolerance to authoritarianism is very widespread and not limited to just police.

We're not just afraid to be anti-authoritative, we're institutionalized since our birth in schools and the concept of control is in embedded in every aspect of life (such as in language found in politics, school work, or newspapers).

Mass-surveillance is just a more direct implementation of "panopticon" [2] applied to everyday life, existing at all times. Having committed a crime is no longer the requirement to be imprisoned, whether physically or mentally.

This article is about the prison/police system becoming the fundamental axis of civil society. Schools are run like prisons, and increasingly with police presence. Minority groups are, as always, increasingly targeted for harassment and neutralization. If you get on the radar of the police state, you and your family will be hounded forever. If you are imprisoned, it's more likely than not that you'll be held in solitary confinement.

The article doesn't seem to answer the question I wish I knew the answer to -- how did we get here? What happened that made the United States this way? Was it always like this, behind the curtains, just a nest of HUAACs and J Edgar Hoovers?

As well as mass shootings.http://www.motherjones.com/politics/2012/12/mass-shootings-m...

This current "era" isn't defined by the number or scale of these tragedies but by institutions' and the public's reaction to them. If we want to protect the lives and welfare of the average U.S. citizen our money and efforts would be better spent tackling some of the less newsworthy health issues.


Also the time frame of the Sandy Hook Shooting was extremely brief. The shooter was believed to enter the school around 9:30 the first 911 call was made at 9:35 and the last shot heard was at 9:40 and the police enter at 9:44. The MRAP and other military artillery obviously wouldn't have made a difference due to time frame of the tragedy.

Used to be military surplus stores would acquire military surplus and sell them to an amused and subsequently harmless citizenry. All that old equipment has to go somewhere; now such civilian possession is prohibited (even used Humvees (basically just off-road cars) cannot, by law, be sold to the public), it ends up routed to the only group legally allowed to have it and wants it: police. In the meantime, stores that sold military surplus have adapted by selling military-like knockoff gear, and would-be buyers are pumping money into the fast-growing "tactical gear" market.

Fact is, if all this military equipment were sold on open market, no harm would come of it. Used to be available and wasn't a problem then, and the rather large paramilitary equipment market isn't a problem now. Question is: why is the government so afraid of its own citizens possessing such gear?

One of the underpinnings of the U.S. Constitution is the Bill Of Rights, one of which states "A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed."

People go bouncing off the wall around this issue as if it were one having solely to do with owning guns, but the real purpose is arranging the real power in the government. The people reserve and are ultimately responsible for the use of lethal force in the United States. They can delegate that power to the government for certain things, like a defense department or law enforcement, but at the end of the day, it's everybody carrying guns that are responsible for social order. At least that's the way it was set up.

As we've drifted away from that principle, by assigning more and more powers to the defense department and police agencies, (gun control is part of this but not the only part), those folks have quite naturally started viewing themselves as the privileged few to hold the power to make things go boom. Then we got rid of the volunteer military, further separating the mass of the population from the things carrying lethal force.

So nowadays, if you want to become a specialist in the application of power tools to destroy people and things, you pick one of a few different career paths and become one of the chosen few. This is a VERY recent development. Not 50 years ago it was commonplace to know people who could operate machine guns, explosives, and drive tanks around. To those folks, cops were just another working Joe like them except they wore a badge. On the other side, cops viewed the population as a trained asset to have and use in time of crisis. It was not unusual to consider gathering up as many armed men as necessary from an area to conduct police operations.

But the professionals got involved, and having that kind of power was viewed as a terribly complicated responsibility that the average guy couldn't handle. This created a wall in society. On both sides now, it's us against them. We need MRAPS because, hell, anything can happen, and there's just a few of us cops in this county. We are no longer all in it together. It's not like if AQ comes knocking we can knock on doors and ask for help.

This is a self-fulfilling feedback loop: as the police arm themselves more and more with special gear, the average person really can't operate it. So even more specialized training is required. Same goes for military gear, where this divide originated.

I would suggest that what we need is some sort of ready reserve system where everybody is trained at reaching 18 on how to safely use most all common forms of police and military gear. I'd further suggest that local police departments be required to have a certain percentage of their patrols as civilian ride-alongs.

There are a lot of things that can be done here, and we don't have to argue gun control to make progress. But I think we do need an understanding of how we got here in the first place. This is a trend that has been a long time coming. The War On Terror just exacerbated it.

What's striking is the correlation between excessive police tactics and enforcement of victimless crimes.

From a right libertarian point of view, it is the government's responsibility to protect your rights, not to protect you.

From a left libertarian point of view, it is the government's responsibility to demonstrate that the good of enforcing a law outweighs the loss of individual freedom and other harm of enforcing it.

Drugs, immigration, fail those tests. Many sex crimes fail those tests. Seatbelt laws probably fail.

The police have to be so aggressive about these things because they never lent themselves to enforcement in the first place.

This is AMAZING! We're getting closer and closer to a cyberpunk society (unfortunately, authoritarianism is necessary, but not sufficient for this). Soon it'll be like Escape From L.A. or Snow Crash or Neuromancer!

I can't wait to stroll down the streets of Chiba like Case.

I can't wait to hack around in the Metaverse like Hiro.

I can't wait to explore the underbelly of prison-islands like Snake.

We just need a bit more authoritarianism, some advanced cybernetic implants, and just enough unrest for a Modern Wild West to be born.

Please see historical and global context related to 'police-state' and despotism in order to understand the significance of these issues. You will need to set aside your American exceptionalism.

I do have an issue with the article though. My middle school did have quite a few young criminals in it, and a zero-tolerance policy would have been beneficial for everyone. Instead, quite a lot of physical violence and theft was dismissed as 'bullying' which resulted in escalation. I know for a fact that many of the students who misbehaved in less extreme criminal ways (and were allowed to get away with it) did enter into a life of crime before they were halfway through high school.

So there is a difference between militarization and despotic control and disciplining students enough to prevent them from becoming criminals.

I think that rather than worrying about harsh penalties for vandalism etc., take issue with the propaganda being fed to students and the lack of focus on problem solving outside of narrow domains.

Americans really should learn more about the Soviet KGB and its predecessor, the NKVD, and how they ran a campaign of terror against citizens who did little more than have a different opinion of how the country should be run. Because now that America no longer compares itself to the Soviet Union, this is the kind of police state that is being constructed in the USA.

Meanwhile, in Russia, the place where the Soviet system used to be, they have moved in the opposite direction and dismantled most of the police state. In Russia people have more personal freedoms with respect to the state than they do in the USA. Of course one unfortunate side effect of so much freedom is that there was a great increase in corruption and the growth of the oligarchs after the fall of the Soviet Union. But Russia is dealing with this step by step, reducing corruption and reigning in the oligarchs. Their ideal seems to be the USA of the 1960s or 70s, but not the USA of today.

I generally agree with the article, but I object to this section:

"And the mood is spreading. Take the asset bubble collapse of 2008 and the rising cries of progressives for the criminal prosecution of Wall Street perpetrators, as if a fundamentally sound financial system had been abused by a small number of criminals who were running free after the debacle. Instead of pushing a debate about how to restructure our predatory financial system, liberals in their focus on individual prosecution are aping the punitive zeal of the authoritarians. A few high-profile prosecutions for insider trading (which had nothing to do with the last crash) have, of course, not changed Wall Street one bit."

I think that the self-serving, damaging actions of those with a lot of power that affected the entire world's economy is worth looking into at least some prosecution, it's hardly in the same league as what happened to three innocent teenagers waiting for a bus. And if insider trading isn't related to the last crash, then of course prosecuting it isn't going to change anything.

Here's what I don't understand: what is the ultimate goal of this newfound desire to police everything? The obvious answer is control over people en mass, but say that happens...then what?

Articles like this (which I'm glad are being written) point out the flaws and injustice in the system, but don't discuss the presumed results "those in control" are looking to achieve by manipulating it.

From what I understand, the desired result is to minimize the autonomy of the general public and funnel the bulk of money, control, and power into the hands of a national elite. What happens next (an honest question, as I have some semi-paranoid theories but am curious to hear from someone who is a bit more educated on the topic)?

A few minor mistakes (perhaps just in my eyes), but overall pretty good.

The hardest part about teaching linear algebra is that nobody explains the big picture. I teach mathematics and computer science and regularly tutor linear algebra students, and I encounter students all the time who ask me "What are vectors good for? I thought all we cared about were matrices and doing RREF and stuff."

For this reason, I deemphasize computations and emphasize the connection between linear maps and matrices. It can be summed up as follows: if you fix a basis, every linear map is a matrix and every matrix is a linear map, and operations on functions (like composition, inversion, whatever) correspond to operations on the corresponding matrices.

It's definitely not an analogy or anything in "scare quotes" that would imply something different is going on behind the scenes. It's exactly the same thing.

Other questions usually left out of discussions about linear algebra (and these notes): what are orthogonal vectors good for? Why would we ever want a basis besides the standard basis in real Euclidean space? Is Euclidean space the only vector space out there? Do vectors have to be lists of numbers?

dmlorenzetti 8 hours ago 1 reply      
It's a little surprising, in a "no-bullshit" discussion of "theoretical and computational aspects of linear algebra," to see matrix inversion touted as the way to solve linear equations. The guide literally introduces the examples by saying "Dude, enough with the theory talk, let's see some calculations." Yet standard numerical practice avoids literal inversion, in favor of factorization methods.

E.g., It is common practice to write the form A^{-1}b for economy of notation in mathematical formulas... The trouble is that a reader unfamiliar with numerical computation might assume that we actually compute A^{-1}... On most computers it is always more effective to calculate A^{-1}b by solving the linear system Ax = b using matrix factorization methods... (Dennis & Schnabel, "Numerical Methods for Unconstrained Optimization and Nonlinear Equations", section 3.2).

E.g., As a final example we show how to avoid the pitfall of explicit inverse computation... The point of this example is to stress that when a matrix inverse is encountered in a formula, we must think in terms of solving equations rather than in terms of explicit inverse formation. (Golub and Van Loan, "Matrix Computations", section 3.4.11).

A little observation: You repeatedly use language that fails to distinguish definitions & properties vs. effective computational methods.

For example, in section G:

> To find the eigenvalue of a matrix we start from the eigenvalue equation ....

Solving the resulting equation is one way of computing eigenvalues. But it might not be the one you want to use in some practical situation.

Just before that, in section F:

> The determinant of a matrix, ... serves to check if a matrix is invertible or not.

It is true that a square matrix is invertible iff is has nonzero determinant. It certainly is not true that, for a matrix of any size, computing the determinant is a good method for checking whether a matrix is invertible.

It's easy to imagine the kind of data government has, imagine its ability to process that data, and easy to interpret that they will do it. But it's also important to recognize that this is conjecture.

From my experience in government: they nailed the user experience (check out http://dsbs.sba.gov for some awesome gov UI), but really overestimated government's capacity to build intelligent technology like this.

I know this will make me unpopular amongst this crowd, but The truth is, I'm far more afraid of data like this getting into the wrong hands because it's being stored improperly or insecurely, than I am of government being malicious with it. Heck, I'm more afraid of my insurance adjuster than I am a malicious cop.

This article attempts to show what a local government could do, but does anyone have access to the sort of location dataset that could give one an intuition about how likely it would be that individuals would be singled out using the data shown?

The article uses maps of Peoria, IL, so let's assume we're dealing with Peoria. There appear to be roughly 115K people between 18-64 in its metro area (http://www.wolframalpha.com/input/?i=population+of+peoria+il...), and 11 traffic cops. (http://www.peoriagov.org/peoria-police-department/police-div...)

These cops appear to arrest 23 people per month for driving under the influence, and hand out about 1750 other traffic citations (not linking directly to the PDF to save their server but you can find it under crime stats).

The article implies that there would be more traffic stops due to increased DUI suspicion, and it certainly seems that it could happen, but given these population, police, and police activity numbers, and given that the article itself gives a false-positive example, how likely would that be? Is it reasonable to think that these cops currently have a lighter load and have time to be dispatched to investigate a potential DUI?

I am not suggesting that it is of no concern for the government to have unfettered access to data, and I can imagine a vast number of possible scenarios in which the data could be misused, but possibly we can better quantify that concern.

Meet Jack. Or what the government could do with all these planes

>Article showing how half of San Francisco gets bombed

This argument can only hold on water by having a complete lack of faith in the rule of law.

The biggest issue I have with this is that this describes a massive , coordinated system to use all this location data in ways that are way outside the legal framework in place by the initial court order from the FISA court.

Stuff that has come out of these leaks have ranged from banal (oh, we listen to the German Chancelor's cell phone? What else is new) to absolutely damning (forcing companies to hand over SSL keys). But even in the most damning cases, all of these happened within the legal frameworks given to them (such as the National Security Letters) and maybe some overzealous law enforcement agents. The illegal incidents can be explained more by incidents outside of how things are "supposed" to work (LOVEINT is probably not sanctioned by the NSA), and a lack of strong implementation of the framework given by the courts.

The narrative has always seemed to be "check out how the NSA is going crazy over here!". But the reality is "check out how all these politicians are voting in these new laws allowing this to take place!"

From the leaks you can even see how the courts are constantly reeling things in, the system is actually working. We hear about old NSA programs that got shut down because of the FISA court's rulings. This is how rule of law works! We vote laws, and people follow them.

To actually come to this, given all we've seen from how courts rule on this issue in general, and the FISA court's rulings, this sort of data sharing would absolutely definitely not be allowed to exist. No judge would agree to this being allowed to be set in place, as it so obviously goes against 4th ammendement in such a program's intent.

Just because the data is at the NSA doesn't mean they can use it however they want, just like how Google would run into some problems if it tried to sell the contents of your e-mails to somebody.

This anger at the NSA should also be directed at the congressmen voting for these laws of large scope in the first place. Hopefully we can get rid of NSLs too. But the NSA is just doing the most it can with the tools we give it (which is what we expect). And rule of law is actually working, we just have some shitty laws.

While pervasive tracking is indeed a problematic state, I still find it humorous at how competent we truly believe the government to be in retaining accuracy in all this data given how often our interactions with government and private businesses revolve around them FIXING their data about us.

These frequent updates are going to kill Firefox and it's partially Google's fault. Basically, Google has managed somehow to coax Firefox developers to rapid release cycle with frequent Chrome updates. But this goes against Firefox users.

Why do people use Firefox? Most users claim extensions. What breaks extensions? Frequent updates. Effectively annulling the most compelling reason to use Firefox.

This is certainly my experience. Pentadactyl, the most compelling reason for me personally to keep using Firefox is more broken than not. Every single update in the last year has broken it and sometimes in non-trivial ways, and stretching my patience to the limit. If I have to abandon Pentadactyl, I really don't have a reason to use Firefox anymore.

UI changes proposed in Australis are not something to look forward to either esp. if you like hiding Firefox UI elements and basically just keeping undecorated minimal window with Pentadactyl.

Is there any way to update Firefox on Linux without resorting to ugly methods like running it as root and using update UI, or downloading the mar file manually and running the updater CLI tool with that file (as sudo / root)?

The issue is that I use stock Mozilla build (I prefer it to Iceweasel on Debian), so I just placed it in /opt, but I don't want to give write permissions to the firefox directory to my primary user (it's kind of bad security wise). Because of no write permissions, updating UI can't update the browser naturally, unless I run it as root. And manual mar + updater method isn't nice either.

Potentially there can be some better ways for updating:

1. Firefox can work with policykit and request authorization for updating (if user has it - it can ask for password). That's much better than running as root.

2. updater CLI tool can detect all the settings, channels sources and etc. from Firefox local DBs, and instead of forcing the user to manually grab some mar file, it can go and perform all that automatically. updater can be run with sudo still, but avoid all the manual steps.

Both these methods would be much neater than what I usually do now.

About gstreamer video playback: I didn't find a way to prioritize formats. Let's say some video is available in VPx (WebM) and H.264 (mp4). Firefox will pick first whatever is listed first on the page. So for me it always picks H.264 on Youtube. I prefer to use open codecs though when there is a choice, but there is no apparent way to set the priority.

I think only every 10 versions should be news. Since they moved to this useless release cycle (basically replacing bugfix releases with major releases), we should shift our news upvoting from major releases to major-major releases (i.e. treat the decimal sign as if it were 2.6x instead of 26.x).

It was always the right answer to feed all available entropy sources (irrespective of previous laundering -- eg. Intel RDRAND gets laundered through the SP800-90 AES-CTR_DRBG internally) into a decent CSPRNG. Feeding multiple entropy sources of different qualities, speeds or backdooredness cannot (by construction) decrease the entropy of the output (it can, obviously, fail to increase it -- say if your ring oscillator got stuck in a fixed bit pattern like the Taiwanese smartcards).

Yarrow and Fortuna are examples of decent CSPRNGs, so I'd say this is a pretty good move by FreeBSD.

Projects like these is where Bitcoin can really shine.

Maybe Bitcoin will conquer the world, maybe it won't. I have no idea.

What I do know is there is real utility in being "electronic petty cash" which Bitcoin can easily become.

Imagine: Alice sends Bob a few bitcoins after Bob writes a particularly insightful comment on HN. Bob then comes across a great blog post by Charlie and sends him a few bitcoins. Charlie then finds an open-source project by Diane that will save him hours of work and sends her a few bitcoins. And so on.

It rarely would get converted to USD and wouldn't amount to much when it did. Instead, people would just earn a bit here and spend a bit here.

Bitcoin enthusiasts miss that USD works fine for most people. But right now it's really hard to do the above scenario using traditional banking. I don't want to connect my bank account to some website to send a someone a few bucks. It's just not worth the hassle/potential risk.

I can't be the first person to think of this. But I'm just not seeing much movement in this direction. Am I overlooking something? Or do I just need to be patient?

I hate to be a party pooper here, but if this project would ever take off, and the project would receive serious amounts of bitcoin that would mean that serious amount of bitcoin would have to be managed and secured by whoever runs that project.

The past has shown that everyone, even persons who run e-wallets and currency exchanges, severely underestimates the amount of security such an endeavour requires.

There's a hundred questions you should ask anyone who asks you to keep care of bitcoin. How large is the hot wallet? How is the offline wallet stored? Where's the source code? What hardware does the service run on? Who are you? What will you do when someone steals your hot wallet? What monitors do you run to make sure the books add up?

So, nice idea, but please make sure this is actually going to be safe.

(BTW there seems to be a way to escrow bitcoin where a third party decides if the transaction should pass, but that third party never gains access to the bitcoin themselves, I haven't read the details of it, but that would seem perfect for this sort of thing)

I like the idea of prepaying bit coins on bounties [presumably tied to an issue/bug report in GitHub] which is what I thought this was at first. As is seems a bit confusing, are all commits treated equally? I'd be peeved if I donated money then saw it get split up among people who did minor clean up, typo fixes, etc. Flip side, I'd be peeved if I spent a bunch of time on a commit then saw the same money go to someone doing a typo fix level commit.

Don't know if the whole intrinsic/extrinsic motivations factor will make this idea crater in any form but I think tweaking the current model is advisable in any case.

Best of luck.

I assume it's not affiliated with the projects at all. This is an independently-run tip system for open source projects. Cool idea.

Key disclaimer though, is that only 95% of donations for tips go to the coders. And if every commit donates 1% of the balance to the commit, that means that the project almost never donates it's full balance. So if this ever really takes off, the original developer of tip4commit will be holding a lot of money that takes a long time to pay out.

I'd much rather use templates that can be rendered server side as an optimization if necessary, and then updated normally on the client.

As for the criticism of SPAs that you need to download the "entire" JavaScript library is loaded, this can be mitigated by lazy loading the dynamic bits. If you look at how Google+ behaves, it renders the page server side, and then loads controllers for various parts of the app on demand. For such a complex app it loads incredibly fast.

It might be a little bit before there's a server-side renderer for custom elements / Shadow DOM / template binding, plus patterns for deferred loading code, but personally I think that will be the way to go in the near future.

  > If your web application is all high-fidelity UI, its completely legit to go this route all the way. Youre paying a high price to buy yourself something fancy. No sweat. But if your application is more like Basecamp or Github or the majority of applications on the web that are proud of their document-based roots, then you really should embrace SJR
and I realized that he's completely right, the majority of the web is still document oriented "pages". If that's your case, don't try to be an "app" and the 37signals way works just fine for you. in other words, it would not be a good idea to make a blog be a Single Page App (I'm looking at you blogger).

pilif 3 hours ago 0 replies      
The thing about SJR is that it lends itself much better to progressive enhancement: if you need/want to present a page which also works without JS, that means that you need to be able to render the page on the server, which means that by using SJR, you can easily reuse that same view code that you already need to have for the non-JS clients.

Of course, as JS on the server becomes more and more wide-spread, you might as well just use the same templates at both ends, but it' still more infrastructure than treating the client JS as just part of the view.

I discussed this back in 2011 on my blog: http://pilif.github.io/2011/04/ajax-architecture-frameworks-...

This is all well and good until you want to handle error responses on the client. Let's say your user is on spotty wifi and they hit the submit button for your form. Guess what happens if that AJAX request fails? Probably a whole lot of nothing, unless you've got some templates client-side to show an error message. At that point, if you're making your error messages fit into each of your UIs, you'd might as well just be using client-side templates anyway and SJR is moot.

On top of that, you can't update the UI in a meaningful way until you get a response from the server.

That's also not even touching any security considerations that you need to make to use this technique: you can't implement a CSP, you've got to make damn sure you're properly escaping every piece of data [in a special way] that comes through, and you've got to make sure the response that you're sending can't be used in a script tag (i.e.: you need to add an intentional syntax error that you strip off) or an attacker could simply put a script tag on his own site pointing at a URL on your site that returns sensitive information.

TL;DR: Badasses only.

There is this interesting pattern of having template compilation be possible from both the server and the client, such as with AirBnB's Rendr. It gives you the flexibility to choose where you want that template compilation to occur.

With regards to Twitter's Time To First Tweet being slow under their Single Page App, I recall Alex Maccaw mentioning that their JavaScript library execution was inefficient, in that the client had to download a whole bunch of JavaScript before it would load the part of the app responsible for rendering the data.

I believe he was suggesting that if Twitter optimised the delivery so that parts of Twitter's JS were served after the rendering part of Twitter's JS code, then the time to first tweet could be faster.

In my opinion, delegating template compilation to the client offers a nice separation of concerns; the server is the API, and the client is the UI.

It would be interesting if there was benchmarking done into comparing these approaches, to see where server-side template compilation can be beneficial over client-side template compilation.

I've been experimenting along these lines with making Rails' partial real-time using websockets and it works quite well for Basecamp/Github style apps. Basically you can get "true" MVC while using your existing erb/haml views and you get real-time updates for all connected clients. Some web apps that are replicating desktop like behavior require full client-side MVC, but I think many apps can hit a sweet spot and get the best of both words of server-side rendering with realtime updates.

Great stuff: we do ad-hock versions of this in a few of our applications. It deserves a formalization.

In my brief thinking about this, one potential version would use HTML 5 attributes like AngularJS, but use HTTP/restful endpoints as "the model". I can imagine a few different approaches, but something like:

<div data-dyna-src="http://myserver/my-div-endpoint" data-dyna-method="poll 500ms"> ...</div>

Which would then poll the given endpoint and swap in new content in a pluggable-but-visually-pleasing manner. http://myserver/my-div-endpoint would serve up the partial of the div, so everything would be DRY. Basically move the model back to the server, but still buff up the presentation layer a bit.

You'd probably need a few different patterns: updateable divs, forms, updatable tables, progress bars, as well as some good default transitions and, of course, make the whole thing pluggable, and potentially provide for both HTML and script interchange at the end point (that's what our ad-hoc version does: it provides a data channel, an html channel and a raw script channel, but it feels like a hack.)

Anyway, if anything is going to save us from the oncoming javascript-filled dystopian hellscape, it's probably something like this.

The web development world has been trending toward a Thick Client. This article is a call back to the Thin Client and centralizing all logic in the app server.

Most devs are still used to the Thin Client approach, so there is a productivity benefit to remain where you are familiar.

However, you can have just as many or more productivity enhancing libraries and practices in client side javascript as in the server side rails-like frameworks.

I just finished "Masters of Doom" a couple of days ago, and I've been on a sort of Doom/Quake/id/Carmack/Romero information frenzy ever since. It is beginning to consume almost too much of my time but very fulfilling since I was a huge Doom fan back when it came out (I created many levels and mods) and I also really liked the early Quake games.

So in the past weeks I read up on all the early id guys, and what became of them after they were fired or left, I did quite some (probably too much) reading on the mess that was Daikatana and how it came to be. I actually find this really interesting, to learn how a project backed with so many employees and so much money can fail so badly, there're probably lessons to learn here (I've even watched somebody play through Daikatana on Youtube).

While being on my search, I've found a lot of interesting or not so interesting things. So if you want to spend some time, here's an unordered list of trivia that I stumbled upon:

- Somebody playing through Daikatana: http://www.youtube.com/watch?v=nm3b0NJzhnQ

- Romero Himself on Daikatana, including a GB port of the game that actually got good reviews (never made it to the US though) http://rome.ro/games_daikatana.htm

- Awful public clash between John Romero and Mike Wilson (former Ion Storm Marketing guy): http://www.kotaku.com.au/2008/01/gamecock_head_tears_into_jo...

- Ravenwood Fair is a Facebook game that Romero did a couple of years ago (so that's what he's been up to recently): http://en.wikipedia.org/wiki/Ravenwood_Fair

- If you read Masters of Doom, you'll remember that it all started at Softdisk, when Carmack and Hall created "Dangerous Dave in Copyright Infringement", a Super Mario Bros copy. Romero uploaded the original game including their level editor, you can find it here: http://planetromero.com/games/dangerous-dave-in-copyright-in...

- Unreleased Doom Midi Music Files: http://planetromero.com/2007/06/doom-archaeology

Sadly, the original Doom editor, DoomEd was never released. I read that it wasn't particularly good (compared to what is available nowadays) but since it was written in NeXTSTEP, I'd love to port it current OSX (or at least give it a go).

John Carmack is only 43. He was 23 when this was released. It still blows my mind how young he is. Notch is only 9 years younger than him. Some people just get good at a very young age. Carmack is still in his prime and his move to the Oculus, hopefully, will bring sci-fi like VR to the masses.

I still play Doom and Doom 2, I even list it as an interest in my HN profile. It's the perfect FPS, to me. There's still a reasonably active community making custom WADs. It's amazing what some people have come up with for this 20 year old series [1]. There's a ladder of difficulty in custom WADs that I've been working my way up over the years before finally throwing in the towel because of Scythe 2 Map 23 [2].

On a side note, John Romero and Tom Hall did an hour long post mortem on the design and development of the original Doom a couple years ago [3]. I found it interesting.

I respect the mastery of the Doom creators, but for me personally, it marked the point where computer games went downhill. Shooting at blobs through the eyes of an anonymous virtual character just never worked for me.

I remember playing Wolfenstein 3D for about an hour, then getting bored with the repetitiveness and lack of identification with the protagonist, and never touching the game again.

When Doom came out, I tried it for 10 minutes, concluded it's W3D with better graphics and aliens instead of Nazis, and never touched it again.

Of course I don't mind that others enjoyed the game. Unfortunately these games became so popular that everything turned to first-person 3D and killed most of the genres I had enjoyed, and so I eventually stopped playing completely.

The chainsaw in DOOM is based on a real model: McCulloch Eager Beaver


Since I've used a professional saw (such as a Stihl 260, a 650 and a Husqvarna 395 among others), the Eager Beaver just looks lame now.

Chainsaws should have a sticker on them that says how loud they are. The three mentioned above are around 115 decibels, three minutes of use without ear defenders will give you permanent hearing damage.

I would argue that Wolfenstein 3D is more responsible for ushering in the first person shooter genre than Doom.

Wolfenstein was original in it's technology, Doom was based on that tech. Both were extremely popular in their time. The main difference is that iD sold their Doom 3d tech (which produced games like hexen and heretic) and did not with their Wolfenstein tech.

Wolfenstein 3D played a large part of driving my interest in computers and learning how they really work under the hood when I was young. Plus the release of MapEdit really made you feel powerful and a young kid getting involved in computers.

Doom is the point where I became interested in programming and it got me looking to how you actually made these games. id Software eventually open sourcing Wolf3D really helped spur that on. On top of that, Carmacks talk and his always interesting .plan file (a blog before blogs) made him seem very accessible and really opened up the world of game programming. I still enjoy going back and reading parts of the Wolf 3D or Doom code to see how they handled certain problems/limitations.

I'd agree with the other poster that 'Masters of Doom' is a great read and worth it to grab if you haven't read it already.

Academia.edu slammed with takedown notices from Elsevier venturebeat.com

jval 9 hours ago 1 reply      
Academia.edu face the same problems that all players in this space do, namely that almost all content in journals is owned by parties other than the authors themselves. It is almost like starting YouTube in a pre-handheld camera era, where the only videos are those produced by studios, and then targeting actors to have them upload the films.

Now that Elsevier have acquired Mendeley, they have chosen a winner from the battle between Mendeley, Academia.Edu, and ResearchGate. It is going to be fairly binary from here on in for the other two parties. Either Elsevier and other commercial publishers will try and sue them out of existence, or send them enough takedown notices to render them useless, or they will acquire them. Either way I can't see an endgame here between these three businesses that doesn't result in the academic publishing landscape remaining almost as balkanised as it was 5 years ago.

I think the ultimate winner in this space won't look anything like Academia.edu, RG, or Mendeley.

It's probably irrational, but Academia.edu's domain really annoys me - I dislike a company using a .edu domain. It feels deceptive, in some way.

Osmium 12 hours ago 1 reply      
So I decided to finally fill out my Academia.edu profile recently and found there was no easy way to add papers. You could upload them or "import" them from another website, neither of which I could do due to the ambiguous copyright status of my papers, but you couldn't enter them manually. The most obvious and unambiguous way would be to enter a DOI, and have them query CrossRef for the paper metadata, but there seems to be no way to do that?

So, in a sense, are Academia.edu not encouraging this behaviour (which is frequently copyright-infringing) by making it hard to add references without actively uploading the pdfs themselves?

gjuggler 13 hours ago 2 replies      
There's nothing controversial here Elsevier merely bumped up the rate at which they're sending Academia.edu takedown notices for obvious infringement by its users.

What's more interesting to me is that ResearchGate, a site which is virtually identical to Academia.edu in its "mission" and design, has been redistributing a shockingly large number of Elsevier PDFs for a long time. Unless these google searches are misleading, there seem to be many thousands of them:



I'm really stumped as to how ResearchGate gets away with this, but Academia.edu is getting hit with DMCA takedowns. Maybe Elsevier and other publishers haven't yet learned to reliably "find" ResearchGate's shared papers, or perhaps they've come up with some arrangement that allows them to publicly share thousands of paywalled PDFs with impunity?

Knowledge sharing, MOOC's (massive open online courses) and open source education is awesome and gives accessibility to the best information in the world.

And like paying for love, sometimes pimps want to control the market. And is that necessarily wrong? Because to make knowledge profitable means to make it sustainably accessible.

He happens to have been recruited by the company years ago from his blog on library science, and now he works on finding up-and-coming knowledge innovations.

Author here.

If you use this on top of programs like bash, well ermm, you get what you deserve ;).

Here's an example of how I used websocketd to create a little dashboard for monitoring Linux CPU/memory/IO stats. It basically uses websocketd to stream the output of vmstat to a web-page that plots the numbers: https://github.com/joewalnes/web-vmstats

Other useful examples: tailing log files, executing long running job and monitoring output, or interactive querying of datasets that require a long running 'cursor'.

This is not for everyone or everything. Remember that like CGI, a process is forked for each connection so it's not the kind of thing if you want to handle a million concurrent connections on a single server.

However for dashboards, admin tools, quick mashups, visualizations, etc - it's a pretty handy tool.

For some stupid reason I hadn't considered that logging stdin/out/err to a web interface for my node.js web apps via websockets. To think, I made a browser-side web IRC interface, and didn't consider this. It would be so useful for my clients, who don't know how, or find it too archaic to ssh in.

To just open up the admin area and see what's going on, provided they're indeed full-permission admins. Then, to actually send input from said interface, that could make ssh'ing into the server something one need not do often beyond initially setting up the app.

Thanks for the idea. Assuming we're not running as root, and the admin side of things is secure, am I not considering any critical pitfalls of this approach? Also, any frameworky cmsy thingers that already do this? Is this new, am I a unique snowflake?

Silicon Valley startups might not think it's a big deal, but being able to run entirely on a private network (either "behind a firewall", or an entirely disconnected network) is pretty huge. Without AeroFS, your choices today kind of suck, especially for 10-500 person companies (or bigger companies where your corporate option sucks or isn't available). Dropbox doesn't work if you care about security. You're left with various forms of SMB crap, more backend-type things like iSCSI, or either blasts from the past (nfs, afs) or science projects (zfs).

An "enterprise Dropbox" conversation is one that many customers will have with AeroFS. I know this from experience trying to sell this very type of product.

The challenge is that sales cycles are long and potentially high touch. One way to mitigate that is by getting sales distribution through 3rd parties. But avoid integrating with a bunch of 3rd party storage platforms unless you get commitments for leads from the vendors. In other words view integration efforts as an engineering to sales arbitrage.

kirillzubovsky 14 hours ago 0 replies      
Sounds like a great idea, especially for all the companies that are thinking about building their own cloud. I suspect building is their highest cost, and if by plugging AeroFS in that could be eliminated, that sounds like just the right way to go!

I am curious, what other sales mechanisms and/or software packages have you tried before you settled on private cloud w/out touching your servers idea?

This may be counter-futuristic, but what if you sold them servers, along with your software? What if you gave your clients the best in classes storage, coupled with the best way to manage it? I suspect you've thought about it before and I want to know what the reaction was like.

Enterprise clients are a black box for me, so anything else you share would be interesting to know.

Madagascar is such a beautiful country, with lots of natural resources (oil, rare timber, minerals) and 90% of its fauna and flora is endemic. It's huge, has almost any kind of scenery you could wish and is easily one of the most interesting places to visit on earth.

Those interested should check out Sir David Attenborough's 4 part series on Madagascar: http://www.bbc.co.uk/nature/collections/p00db3n8

Yet it suffers from extreme poverty, an unbelievable level of corruption at all levels, and an education system that leaves everyone behind (school isn't free, so most kids can't afford it).

In recent decades, poverty has made the population desperate, levels of violence have risen, kidnappings are common, there is no real reason to think that the current elections are going to solve anything, those aspiring to be in power have proven to be as corrupted as those who are already in place.

On top of that, during the cyclone season (hurricane/typhoon if you come from other parts of the world), the island becomes a giant target and gets hammered by bad weather: houses destroyed, roads cuts, etc

In that context, it isn't surprising to learn that old diseases like the bubonic plague could easily get a hold; sanitation isn't high in the list of priorities.

I've always been bothered by what I call this 'life-perspective problem", and of course, I'm always bothered more when something horrible like this happens. (The preceding statement has its own problem buried in it- because something horrible is always happening, at every second.)

I've spoken about it in other forms- "procrastination should be solved by lighting fires, not filling buckets" and so on. There is powerful emotional energy to be harnessed, but a lot of us (maybe just me, but clearly others too) have no idea how to manipulate it effectively, so we typically go without it. When we do get a flash of inspiration, the energy needs to go into a system where it generates something lasting- otherwise we just get the one-off blogpost or product that doesn't go anywhere. We get tired and everyday life dehumanizes us again.

It's the same central idea: Can we modify our circumstances and environment such that they remind us of the things that matter, in a way that disrupts us from settling into sub-optimal comfort zones?

I used to think that maybe this was a self-indulgent problem that I had, simply romanticizing the moping around, but clearly it afflicts even highly productive and accomplished persons like Mr. Sivers. Clearly this is a broader human problem- our inability to contextualize things, to see the bigger broader picture except when it's too late, or when we're unexpectedly inspired.

Is meditation the solution? I think meditation is a practice that encourages the broadening of perspective, but I'm sure there are other ways to reach the same destination- I'm sure we could design for it into our media, into our daily lives.

There is some very meaningful work to be done in this "perspective/reminder" space, but I don't know what exactly, and I don't know how to do it. But I'd like to get involved in it somehow, someday, before it's too late.

I hope this is helpful to someone. Thanks for sharing, and thanks for reading.

Sorry for your loss. I used to ride my bike everywhere when I was in my late teens; these days I can't imagine doing that. All it takes is one distracted driver to cause terrible loss.

Riding bikes is super dangerous. I always slow down and give bikes a lot of space. I also think bike riders should ride on slower, non-busy roads whenever possible, but I'm not at all blaming bike riders.

sivers your work is some of the truly best.

I'm so sorry for your loss, I've never lost a close friend so I have no idea what you are going through, but obviously if there is anything we can do to help just put out the word.

Derek -- This is a nice piece in a difficult time. I am childhood friends with one of Milt's sons and know his family appreciates all the love being sent their way. Thank you for sharing with everyone.

Sivers, may you be at peace.

It took a death in my family to make me realize that I needed to "start writing again". That was several years ago and I see myself in some of the old ruts and in some that are newly worn. I wonder how many tragedies before I learn my lesson.

I don't have much experience of FreeBSD, but I'm curious about it: for what purposes is FreeBSD used? Is it common in some work environments?
