Ask HN: Is Facebook secretly keeping accounts open?

They keep plenty of information on you even after the account is 'deleted' (not deactivated) - this much is evident from recommendations, etc. if you ever create a new account a year from now, showing up again as if it never went away

Facebook is private surveillance

I do believe if you (or an app you've linked) logs in to facebook during those two weeks, the timer resets. Make sure none of your mobile devices, browser plugins, and link-apps are doing so

Why do people think the largest social network is going to make it so easy for them to delete their stuff? Your data is money to them. They don't give a crap about your privacy rights. Deleting/deactivating your account is doing nothing but making a tick in their database from visible to invisible.

I think the only real solution to this is not to deny information to facebook, but to trivilize the information given to it. Fb already has all our data, now whether you delete it or not, they'll have it, either as visible data or as archives of back ups, they have it. What we should however do is what Adam Huxley suggested in brave new world that by filling in so much irrelevant information, you make it possible to drown out the valuable information.

I wont classify, I wont categorise and I won't tag, I will not create albums, I will just keep uploading everything everywhere. I will try face-detection with different people and my cat. You get the idea.

If enough people over use / abuse the fb with loads of insignificant info, FB's game will backfire.

I've got a friend that had her account deleted for awhile and then logged into Spotify; apparently, Spotify silently reactivates Facebook accounts if you use the same email for both services.

YUP. I created a fake account with a new name and email. IT figured out who I was pretty shortly. Dont know how, but there are many ways they could do this. For one, I added similar friends, and used a similar name.

Its the facial recognition that really creeps me out though, and the fact that cops always are recording cameras at community events and protests. Supplier meet consumer.

I deleted my account six months ago or so and just tried to log in, which failed. Is it possible you just deactivated your account rather than scheduled it for deletion? Could another app have authenticated as you and reset your countdown?

We were using campaignmonitor.com until we found out about sendy.co

Sendy uses SES to send the emails on our behalf - so far so good - we do a weekend update to about 1500 address (so far) and it's worked quite well.

Someday I'll script something to dumb the current user email list into sendy so I don't have to export it to csv and reimport it every weekend...

I was in a similar position 4 years ago, before my first startup.

On reflection, the books I got the most out of that actually shaped my behaviour are...

THE PERSONAL MBA, JOSH KAUFMAN

Was blown away by this. Couldn't believe how much stuff I didn't know about. It covers everything you've asked about and more...

It's also written a bit like a Software Patterns/Recipes book, which I love.

I've read the MBA book about 5 times.

http://www.amazon.co.uk/Personal-MBA-World-Class-Business-Ed...

PITCH ANYTHING, OREN KLAFF

You'll hate reading it. It will make you cringe. It's uncomfortable.

But it changed my attitude to business, my products, and deals a LOT. Which is REALLY important.

Applying some of these techniques had amazing results in any dealings with 3rd parties (sales, partnerships, deals). That's because I'm a softie engineer, not a battle-hardened business man. I still read this before attending any significant meeting.

http://www.amazon.com/Pitch-Anything-Innovative-Presenting-P...

HOW TO BE THE LUCKIEST PERSON ALIVE, JAMES ALTUCHER

Covers everything in one way or another...

I keep coming back to the epic rule list in this book. I keep ignoring them in business, then learning the hard way that the list is right. He shares his failures and successes in a humerous way.

It's a real down-to-earth, eye opening book.

http://www.amazon.com/dp/1461120705

OTHER

I'm reading Lean Startup, and have read Made to Stick, Letting go of the words, Ignore Everybody, Spin Selling, and tons more. All good books, but the 3 above were the biggest impact for me on all levels.

meerita 28 minutes ago 0 replies      
My suggestions:

Using bootstrap or another UI Framework would surely improve many things, from the UX/UI side. At least it will help until a pro UX can work on it a lot more.

Bootstrapping also will make you code better since the foundation of the code is well done. It also works on mobile and it's easy to catch up as well to tell other developers to manage our codebase, bootstrap has good documentation online and you can do, practically, almost all kind of UI compositions with JS.

After that, I would follow Google Pagespeed recomendations to reach the 100 points and have something like my blog wich loads in 300ms-500ms.

spangborn 1 hour ago 2 replies      
Hire a designer - the UI and UX could use some work. Here's some of the design feedback I'd give you:

- You're not utilizing the whole width of the page, and the table looks pretty compressed, making it difficult to read.

- You're also not using the whole height of the page. The pagination would be more useful if there was more content. It's silly to waste that much real estate.

- The icons in the top right are too small and the third (mailing list) carries no meaning.

- Your logo in the navbar is too small, or at least the text. You probably don't need the text in the logo if you've got the heading there.

- Search is in a pretty unintuitive location - try putting it in the top right of the layout.

Edit: From a functional perspective, you've got duplicated stories on the home page currently. Same exact link, two different titles.

Ask HN: what alternative to Google Reader have you chosen?

ksec 5 hours ago 0 replies      
It depends, i suppose you are asking for an Web alternative.

I haven't tried Digg or AOL Reader since they aren't available. My usage is basically a headline view of all the feeds, I have them in different catalogs. I will scroll through them to see anything worth to read, and open it up as a new tab as i go through them all.

Newsblur is very non Google Reader like. I suppose it fits some of the pattern of flows of a particular niche. But not me.

Yoleo is great except it doesn't work very well with non Unicode Feeds and it is quite slow. Unread count is overlapping. I think it is a solid app given some more time to develop. But I use Reader everyday or every 4 - 6 hours i cant afford to wait.

Feedly web works well so far. It is the closest thing to Google Reader in Headline views. The thing i dont like are performance and slow scrolling in some cases. But it generally fits me well.

The thing is, there is nothing wrong to try everything out. It is only a click of a button for your Google Login.

paulhodge 1 day ago 1 reply      
I tried Feedly but I didn't like how slick & clever it is. It seems to decide (based on popularity) which new posts to show me, when all I really want is a categorized listing of everything that's new. I like a good old-fashioned list where some things are 'unread' and some things are 'read', but in Feedly this seems to be fuzzy concept.

After trying a few other services and apps, I switched to NetNewsWire, which is a client-side Mac app that does what I want. Pretty happy so far.

Aside from this, however, I would have gone with Old Reader. Feedly is a good choice (especially with their new cloud platform), but last time I checked, they didn't let you export your feeds. If you don't mind that, Feedly is a great choice.

Pencil + paper.

Then zap it with my DSLR. Or if it needs to be published, use Dia and export SVG/png into target document.

I occasionally write out graphviz stuff from my code using a very light weight library I wrote (C struct to stdout) if I'm trying to visualise what is in memory at a point in time. This has been invaluable whilst knocking up a simple mark-sweep GC for a project I was working on.

Whats the fastest JSON C serialization library?

mh- 2 days ago 0 replies      
Check out ultrajson (aka ujson) - (also see ujson4c[1] in the same org)

as far as serializing, ujson is 7x faster than simplejson in the worst cases I've seen (disclaimer: using the Python bindings.)

[1] https://github.com/esnme/ultrajson

[2] https://github.com/esnme/ujson4c - "A more user friendly layer for decoding JSON in C/C++ based on [..] UltraJSON"

n.b.: There also exists a class of "simplified" JSON serializers. They implement most of the JSON specification but leave out some features (or restrictions) that make it more expensive. I don't know anything about these, perhaps another commenter can chime in.

crowdfund a new political party with pro bill of rights, anti-corporatist smaller government platform

specific prohibitions for fourth amendment abuses

better whistle blower protecting legislation

supporting constitutional amendments for all of the following; ending corporate personhood, enacting real campaign finance reform, restoring Glass Steagall)

breaking up all too big to fail corporations

when enough money or risk to life is involved making it a capital offense/ treason to: supply false testimony to congress or government regulators, etc, or to disseminate false information to the public or business (eg LIBOR distortions), or to unnecessarily make classified any such information

smaller, better government through 'government as a service' Govt 2.0 ideas (see g.g. Lessig), testing legislators on content of bills before they can vote on them, line item vetoes

This party would recruit its candidates (not accept those who nominate themselves) through a computerized equivalent of the way honeybees choose a new nest (see Sealey Honeybee Democracy). Candidates would have to have a track record of volunteer service and a minimum history of published political writing addressing actual legislation - (likely drawing heavily on bloggers and academics).

This was required reading for me (and most others) while going through the Marine Corps officer training program... A great read and probably one of the core reasons to hire former members of the military (in my biased opinion) along with a handful of other reasons that can't be taught in school.

The officer selection program screens individuals for potential to lead and thrive in a variety of very stressful situations THEN once they've screened for top performers they assign them a job and train them how to do it.

A completely different process than most companies who expect all of their talent to show up with a very specific skill set. Unfortunately this leads to some amazing people being excluded for the talent pool because "it is too much work to train" someone. If one learns the traits to look for I'd guess that training them becomes a breeze and you'll end up with a better hire who will stick around in the long run.

Ask HN: How to focus and work on something that you hate and disgust

projectdelphai 5 days ago 0 replies      
Three ideas:

1. Write a list of things that you need to do each really small implementations and keep it in front of you (I use google calendar tasks and keep it in an open tab next to you). Each time you finish a task highlight it or check it off. After a while, each unfinished bullet point will start to bug you especially the longer its been unfinished (at least for me). This helped me finish tasks I hate just because I hate it being the only unfinished task on my list.

2. I can't remember where, but I once read a statement by a coder who said that if a change is too hard implement [in code] restructure the code so that the change is easier to do. I would suggest that whenever you need to work with a section of code that you rewrite it so that you understand it better and can work with it. After all, its your project now, not the old developers. This will take time, but if you plan to stay with the codebase for a while, it might be the better option.

3. And then of course, you could just chug away at the project and work your way through it. If you just want to finish it hard and fast, I would suggest the Pomodoro Technique. I always prefer #1 than the pomodoro, but I've read a lot of people that swear by it, so it probably has some value.

Try using tapping, the EFT (Emotional Freedom Technique). It's endorsed by Dr. Mercola (http://eft.mercola.com), amongst others. It looks really silly, admittedly, so don't do it around people with which you want to maintain a level of respect, but I've personally used it at times. To be clear, I'm not sure if it truly unlocks the emotional blockage, or whether it's the personal embarrassment of having to put yourself through such a stupid looking exercise that makes you want to JFDI.

I'm sure this will attract some jeers, but I'm not saying this is explicable and robust science--but it got me the desired effect.

Try to develop a rapport with them where you can joke around and talk shit to them. But overall - there might be some who won't want to ever work with you, and that's not your fault. All you can do is work with the one's who do want to work with you, treat them like gold, and most likely, the other ones will come on board over time. That goes for everyone who reports to you.

Work with the ones who do want to work with you, do good work and let upper management know about it, and wait for the other ones to get on board.

Not really sure what you are looking for by the title, but I would go where the money is. There are tons of energy companies (many are mandated to do environment analysis) that hire data scientist and/or analysts. One example is SUNCOR [1], but there are tons of supporting engineering firms that provide services to these types of companies too. Just google a few and then look for firms that provide services to them. If you're new to the industry, I'm guessing you are, since you're asking, then start trolling these sites and look at the job postings, these will tell you the types of skills / certifications they are looking for.

Most of the issues mentioned so far are trivial or just warts. The real issue is understanding the design patterns that work well enough to build high performance applications. Also in order to really exploit the power and productivity of Haskell there is quite a learning curve.

We built an algorithmic trading system, and almost everything else in Haskell. Our code base is over 100K of human written code.

The major library gaps were a time library (you can find a version of what we have been thinking about releasing at https://github.com/time-cube/time-cube). We use our own build system that drives cabal and ghc. Otherwise having many libraries is just painful.

We found that composing applications as conduits to be a very effective design pattern that minimizes many laziness issues. Monad transformers are very powerful but the machinery for them (like forking) is not fully cooked.

Maintaining the codebase is far easier with haskell than with anything else I have worked with (C/C++,C#,Java,etc...). Refactoring in Haskell is great.

You can't fight the language. Fighting with Haskell will cause great pain. When you go with the flow, using lots of strong types, higher order functions and can apply things like a monoid instance to a problem the language is a joy to work with.

Debugging is more painful than it has to be. There are still times when you need some real GDB wizardry.

The runtime is somewhat immature. It locks up oddly sometimes under heavy load. Dealing with latency and queuing issues around gc pauses is much less understood/documented than in the JVM world. The set of best practices in general for doing intense things with the ghc runtime is just still young and sparse.

STM can exhibit something that looks a hell of a lot like livelock.

Error handling is brutal. Catching all classes of exceptions (at the place you want to catch them!) for recovery is surprisingly tricky. This isn't necessary in theory with things like MaybeT, but in practice, lots of odd libraries use things like partial functions and the error function.

Not having tracebacks in production code is painful

The library community is thriving but it has a lot of volatility. Things break each other quite frequently. Semantic versioning either isn't enough to save it or hasn't been adhered to strictly enough.

Thunk leaks and other consequences of unexpected laziness aren't as common as people worry about, but they're kind of a pain to track down when they occur

Strict vs. Lazy bytestrings, String, Text, utf8-string, etc. You may find yourself doing a lot of string/bytestring type conversion

There's still wars raging about the right way to do efficient, safe I/O streams. Conduit vs. Enumerator vs. Pipes etc. They're all turning into pretty compelling projects, but the fact that there are N instead of 1 is sometimes a drag when you're dealing with libraries and dependencies.

There are not a lot of good open source "application server" type frameworks that really handle thread pooling, resource exhaustion, locking, logging, etc, in robust nice ways. We have one internally, and I'm sure a bunch of other haskell-using shops do too, but the ones on hackage are not nearly sophisticated enough (IMO) and I suspect not very battle tested against the kinds of ugly queuing problems you run into in highly loaded environments.

If I think of more, I'll add em... these are off the top of my head.

Haskell's record system (analogue of C's structs) has two major deficiencies.

1. Modifying a record value (that is, making a copy of a record value but with different values in one or two of its fields) is unnecessarily complicated and uncomposable. This makes modifying a subfield painful.

2. Field names are in the global namespace. Thus you cannot have e.g. a field named `map` (conflicts with the standard `map` function); nor a local variable named `owner` in the same scope that you use a field named `owner`; nor may two different record types both have a `name` field. C had this problem in the 70s (which is why e.g. struct tm has tm_sec and tm_min fields instead of sec and min fields), but they solved it a long time ago.

The solution to deficiency 1 is to use lenses. Use the lens package from Hackage, but don't read its documentation at first: it generalises the problem exceedingly well, but this makes it harder to understand at first glance. Instead seek out a basic tutorial. At the cost of a short line of boilerplate for each record type, this works well.

There is no satisfactory solution to deficiency 2. Some people define each record type in its own module, and import each module qualified. I don't think this scales well. I prefer to put a record-type prefix on each of my field names (i.e. the same thing C programmers were forced to do in the 70s).

In my opinion the module system (http://www.haskell.org/onlinereport/modules.html) is a bit weak. For example: "It is not possible, however, to hide instance declarations in the Prelude. For example, one cannot define a new instance for Show Char."

Instances can't be explicitly imported either.

Another thing I don't like is if you have two different functions with the same signature but different implementations meant to give swappable functionality, there's no way of specifying that explicitly. As a user of a library, you just have to realize the functions can be swapped out with modules. For example:

http://hackage.haskell.org/packages/archive/bytestring/0.10....

http://hackage.haskell.org/packages/archive/bytestring/0.10....

It's really not that bad but I do like how other languages allow the programmer to make this explicit.

Records are annoying, but can be worked around. The compiler is incredibly slow and uses tons of RAM (I need 2GB to compile my simple little web app for example). The slow compile times can start to really kill productivity on large projects. The web frameworks are all pretty focused on trying to reproduce industry worst practices rather than doing things right, so if you are doing web development and you don't want your app to be a mess, you are kinda on your own. That's pretty much it.

edit: to clarify on the web thing, when I say "on your own" I mean you won't be able to get much from existing tutorials and examples since you will want to do everything differently. Not that you will have to write your own framework.

bjourne 7 days ago 7 replies      
Let's begin by stating that Haskell is great, but there are a lot of stuff I don't like about it:

1. Way to many user defined operators. Haskell lets you define almost anything as an infix operator which library authors love to (ab)use. So you get operators like ".&&&." (without the quotes) because they are functions reminiscent of the boolean and operation.

2. But weirdly enough, many operators aren't generic. String concatenation is performed with "++" but addition with "+".

3. Incomplete and inconsistent prelude. It has unwords and words for splitting and joining a string on whitespace. But you dont get to specify what string to use as the delimiter like the join and split functions in other languages lets you do.

4. So instead you have X number of implementations of splitStringWith on Hackage, some of which are unmaintained, deprecated or just not working, meaning that just answering the question "how should I split a string?" becomes a big endeavour (http://stackoverflow.com/questions/4978578/how-to-split-a-st...).

5. There are four different "stringish" types in Haskell: List, LazyList, ByteString, LazyByteString. A function like splitStringWith works on one of the types, but not the three others for which you need other functions. Some libraries expect Lists, other ByteStrings or LazyByteStrings so you have to keep converting your string to the different types.

6. Most Haskellers seem to content with just having type declarations as the api documentation. That's not a fault of Haskell per se, but imho a weakness in the Haskell community. For example, here is the documentation for the Data.Foldable module: http://hackage.haskell.org/packages/archive/base/latest/doc/html/Data-Foldable.html

7. This is very subjective and anecdotal but I've found the Haskell people to be less helpful to newbies than other programming groups.

Depends on what you are doing. The library eco-system used to be a weak link in Haskell, but I see it improving. To clarify, there were (and still are) a lot of broken and/or poorly documented and/or unmaintained libraries on Hackage. Or several libraries for doing the same thing where there is no indication of which library is the best choice. I suspect that is, to some degree, the case in any open-source eco-system, thought. Recently, though, thanks to the effort of the giants like Edward Kmett there have been an influx of great well-documented libraries on Hackage. And of course, you are welcome to contribute new packages/improvements to existing packages.

Working with DBs is easy, especially if you use HaskellDB. There are bindings for non-relational DBs, as well as a DB written in Haskell (acid-state).

As for the language itself, you might find it tricky to develop computation intensive applications with large run-time data-sets due to garbage collection (but that is true for any garbage collected language). Other than that, it's one of the best performing languages in the Debian PL shootout. And the fact that concurrency is (comparatively) easy means you can make use of those extra cores.

Monad transformers and monads are fine, you just need to learn how to use them.

To sum up: it depends on what you do and what you consider a "real world application". Might be a good idea to elaborate. For example, are compilers, games, web apps, automated trading systems, android apps considered "real world"? Because any of these has been done in Haskell.

Runtime debugging in Haskell is more rare, but when you need it, it's more of a headache.

Achieving performance is harder than in c or c++.

The ecosystem is strong on some counts and weak in others.

There's lots of API duplication (lazy/strict byte strings, map, set, seq, etc).

Good performance may depend on brittle ghc optimizations that might break in very difficult to comprehend ways if ghc is upgraded.

For me, the biggest downside is lack of solid embedded device support -- arduino (Atmel AVR), android(ARM), iOS (ARM).

After using Haskell pretty much full-time for 10 years, writing C and Java code makes me sad. The support for the above mentioned platforms is in-progress, but is not yet mature.

There are some neat things like Atom which use a Haskell DSL to target arduino.

My other issue is that the garbage collector in GHC is not really sufficient for real-time audio applications because it can pause for too long. GHC HQ has tried to tackle this in the past -- but there is a reason why it is a research topic :)

If your application requires interfacing to a C++ world -- your are not going to have fun. Though there might be a GSoC project for that this summer?

Also, GUI stuff is somewhat lackluster. There are bindings to gtk, etc. And they can get the job done. But they don't really capture the essence of what makes Haskell awesome. We are still searching for the GUI abstraction that really clicks.

Honestly I think the biggest down side is that there's not enough commercial endeavors using Haskell, and thus theres horrifyingly few people working full time on many core pieces of the ecosystem. Yes, my biggest critique is that all the great stuff in the Haskell ecosystem is the result of a small collection of smart folks helping out in their spare time.

It makes me wondering what magic would happen when those folks can work on helping the ecosystem full time!

I have to say that one of my favorite things currently about haskell is how nice and easy the c ffi is to use. So darn simple! (I'm also GSOC mentoring some work to provide a nice C++ ffi tool too).

Theres so many great tools in the Haskell ecosystem, for every problem domain. Its not perfect, and theres always room for more improvement, but those improvements are happening, and the more people invest in supporting the community, the more those improvements happen!

For example, one thing i'll be exploring in the neat future is how to do good Numa locality aware scheduling of parallel computation. It looks like i might be able to safely hack support in via a user land scheduler (though i'll find out once i get there).

My principal work right now is building numerical computing / data analysis tools, and some of the things I'm doing now would be simply intractable in another language.

I found it a lot slower than more imperitive style languages. I've been writing in c-like languages for something like 30 years, so I suppose that's not unexpected. I found that the type system sometimes got in my way. And combining monads (even with monad transformers) was also a faff. In the end I suppose it depends what you're trying to make. I think Haskell is great for DSL applications and less so for things like web dev. Though that being said Yesod is a pretty nice framework.

Hi. Thanks for offering this. One of the many (I am sure) projects on offer.

My project is targeted at the Market Research industry.

a. There is a survey programming compiler, written in yacc (bison)/C++.

b. I also have a cross tabulation engine (another compiler part of the same project), which presents a web interface for Cross tabulation engine (I am using webtoolkit.eu).

The survey compiler can currently compile to UI front ends like:ncurses, webtoolkit, wxWidgets and gtk. The GUI frameworks are all in a very nascent stage. I have also been experimenting with emscripten and using frameworks like dojo and dojomobile. I have been able to get dojo working.

There is also a Random Data Generator, built on the Survey engine.

There is work to be done in the Cross tab engine as well. There is a branch where I am experimenting with SSE instructions to speed up the engine.

Scope of work is wide and I can get help you get started with anything you find interesting to work on. The project is open source and hosted here:http://sourceforge.net/projects/xtcc

website: http://qscript.in

Active git branches: nc, web-questionnaire-2, rdg, xtcc

You can email me at "nxd" underscore "in" at yahoo dot com

Unfortunately we are a single person startup and no funding, everything is being done my me at the moment. If you are looking for something like this to start an interning/job relationship, then this might not be the best project.

Thank you for your offer once again and hope you get something that is a close fit to what you are looking for.

Well, if you're "installing it now" it's a little late to ask, isn't it? :-) I put it on my iPhone 5, which is my primary phone. Having been through many betas before, I'm prepared for some things to not work. Previously, mail, SMS, and phone functionality have always worked and that's what I expected this time. Those important functions work reliably in iOS7.

I've restarted once because something in Safari locked the whole phone. Some apps are broken (Podcasts), or look wonky in spots (Find My Friends). Everything mostly works, though. Even the Pebble app to connect to the Pebble watch. I figured if anything would break, it would be that.

If you want everything to work all of the time, never put the first iOS beta on your phone. Something is always not right. (Last year I was at WWDC, and the new maps app wouldn't render maps for me, just a grid. Not knowing SF that well, that was a major breaking change for me. <G>) Wait until beta 3 or so if you need reliability.

iPhone 4S here:

Pros ~ Two words - Control Center. I can easily change anything that I want without jailbreaking. It seems like they are moving towards an SBSettings-like iOS. For reference, SBSettings is a jailbreak-only package that allows you to change nearly every aspect of your iDevice.

Cons ~ Some apps are broken and will just not really work (ie. Alien Blue) with iOS 7 yet. Lag is very small but just enough to be noticeable. Restoring from a backup may take overnight, depending on the amount of data you already have. Some features can take some getting used to before you feel comfortable (ie. displaced 'delete' button when typing in passcode).
