Logfind
1) 'To consider a solution as 'passed', it would need to produce output on a log file of about 5 GigaBytes in under a seconds.' - you need to firm up this requirement especially if the tool will be scored by an automatic tool

Tweetdensity
1) http://linode.interviewstreet.com/tasks/4890/response1.json

Error: Parse error on line 1:
{ tweetdensity:{
-----^
Expecting 'STRING', '}'

2) Would like more direction for using the Twitter API - you could at least link to the docs for the API route that will give me this information

3) Is there an upper limit on 'count'? I believe there is some limit to how far back you can get data from the Twitter API.

Facematch
Sigh, not going to touch this one - 'See that feature that engineers teams at Google and Facebook have spent months implementing? Yeah, do that in a few hours/days for a chance to interview with a startup!' - the very least you could do is provide some library or guidance as to what tools might be well suited for this task.

Overall
The public key stuff seems complicated and a pain. Why not use Heroku (or let me use my own VPS/ec2 instance)? Or modify the problems so that I run it locally on my machine and submit the results - for Logfind, you could provide a program that takes a seed to generate the 5GB file. When I am ready to submit, give me a seed that will expire in 5 minutes and I have to enter my output before it expires or get a new seed.
I usually am counting in markdown-mode, so I doubt there are any major gotchas.
I'd really like to see a comparison between Node and Sinatra::Synchrony.
This is bad advice. data() takes care of many details that .attr() does not, such as preventing IE memory leaks or trampling an existing DOM property.

I don't understand the issue. He is putting in 1.410 and gets 1.41? Isn't that the expected result?
In what way does the author think this behaviour is wrong?
1.410 === 1.41

If he wanted to store a string, then he should actually store a string. .data() is just a thin wrapper around getting and setting values on an object, which initialises its initial values from the data-* attributes on the element in question (which should always be strings).
But 1.410 isn't a string, it's a float. What do you expect jQuery to do, parse the source of its caller and determine that you wrote 1.410 rather than 1.41? That's the only thing it could reasonably do, because the value it actually receives as an argument is identical in both cases.
I don't think that many are arguing that it's going to be an obvious complete annihilation. The backlash would be far too large if Reddit actually went down. More likely, it's just going to be small sites here and there that are too small to defend themselves, and that not enough people care about seeing go away to make an outcry loud enough for Washington to hear. That's what's really scary about it - that it will have very bad, almost silent effects that few outside of tech notice.

This is a pretty silly article in my opinion. What happened to software? The future happened. Yes, you need firewalls and permissioning now because technology has evolved past a purely trust-based system. Why is this a bad thing?
Discussion of paper with PDF link: http://lesswrong.com/lw/rg/la602_vs_rhic_review/
it's interesting to me that the same folks who wanted Citzens United because it was supposedly pro free speech are also in favor of SOPA which is pretty clearly anti free speech. what they have in common is both favor large corporations at the expense of individuals and the non-rich. more freedom for the former and less for the latter. not a good trend in a country historically and ostensibly founded on individual liberty and non-aristocracy.
The ones passing it now first care more about the money they received, and second, they actually believe what MPAA/RIAA are telling them. That this is absolutely necessary and that they will only use it against serious offender. The thing is, if SOPA existed a few years ago, Youtube could've easily been considered a serious offender. No question about it.

Viacom filed a $1 billion lawsuit against Youtube, because it had so many of its videos posted by users. Also, other sponsors of SOPA, such as NBC, would've wanted Youtube dead, too. After all, the only reason they started Hulu was to fend off Youtube, even though they didn't like having Hulu at all, since it undermines their real cash cow, the old traditional business model.
I would strongly doubt the unaware portion and put more emphasis on them not caring one way or the other.
Here is another example of what I'm talking about:

http://jsfiddle.net/KwjvA/
Yep, latchkey, I think you might want to rethink the article. As others have pointed out, you're seeing JavaScript's behaviour, not jQuery's. And this:

elem.data('foo', { 'a':1, 'b':2 });
elem.data('foo'); // Returns the object

Is certainly more desirable than:

elem.attr('foo', { 'a':1, 'b':2 });
elem.attr('foo'); // Returns "[object Object]"
This will give you false positives when you input characters not allowed by Twitter. I think they only allow [a-z][_][1-9].
", ".join([0,1,2,3,4,5,6,7,8,9]) works well. Why not that?
So, first the article talks about strings, but then does all of it's examples using floats. We all make mistakes. Hopefully we can help with that.

The root issue here is that the developer assumed how somethig worked, and didnt bother to learn how it actually worked.

I actually do have issues with data attribute for this exact reason, but that is no excuse for not looking up how it actually works.
Have you looked at Shark? It can show you where your program most frequently encounters L2 cache misses (or really any event your cpu has a hardware performance counter to track). Intel VTune and the "perf" tool from the Linux kernel also perform similarly.
Hi Thomas and dhkl, thanks a lot for the resources, will look into this and get in touch, that's very useful! :)
Thanks Oo, yes, that would be awesome one day! :)
How does this get around the Twitter API call limit?
Your example isn't very clear. http://jsfiddle.net/4bd23/1/ shows that data read from the HTML attribute may be coerced into a number, while data values set from JavaScript are always returned as the same type.

I can see why they would do this. Having to parseInt all default values wouldn't be very jQuery-like.
Petitions don't work. The Founding Fathers knew that...
We've been through this in Germany. When the Zugangserschwerungsgesetz passed Blogs and Forums were full with tutorials about how you can change the name server in various operating systems. The Zugangserschwerungsgesetz was never implemented so we don't know how many people would have actually used an alternative resolver.
thanks for the enouragement!
The premise of that quote is that something is missing in both languages. In that context, your question is sort of absurd.
Umm, yea just like the marbles in the example. If you have a marble pushed into a pipe with 1,000 marbles the one popped out at the end is pushed out a lot faster than any single marble moves.
> At least that is how the "Zugangserschwerungsgesetz" in Germany works

Worked. It was never really applied and it's been repealed since.
Here's my response that I posted in his comments:

"I needed the State’s protection to be a full human being."

Do you really need the state's protection, or do you just need protection in some form or another? I don't see why it is necessary that your protection come from some organization that forces you to pay for their services. Your argument that you need the state's protection could just as well be used to argue in favor of the criminal organizations you are so afraid of. If you were forced to pay for the mafia's services, would you need them too? I don't think so. There's no reason why your protection couldn't come from an organization that you chose to work with voluntarily.

Agreed that localStorage should throw errors. This is particularly fun:

localStorage['a'] = {a:1};
localStorage['a'] -> "[object Object]"

Crap.
Long before Gravatar, there were Picons
I think that makes it a bit worse. Those debates are more than good enough for a lot of people who don't care much. "Oh look they debated things! Welp, back to the grind!"

Even worse, if enough petitions get that many votes, it could be spun as a problem for politicians who want to get things done, "The public keeps wanting us to debate these stupid issues! We can't get to the more important things!" Yes it sounds far-fetched, but some newspapers will sink that low...

So like, Reddit in 2005?
Interviewers do "leak" information to interviewees. I once turned down a lucrative job offer because, during the interview, the interviewer had told me "hilarious" anecdotes about the CEO changing his mind every few days.

Here's a more technically-slanted list of questions I've used during interviews: http://www.reddit.com/r/programming/comments/apae9/interview...
Can anyone comment on the rates of use of bootstrapping and VC, between old and young entrepreneurs?

My gut feeling is that older people are more likely to have the savings and connections to bootstrap a company, and so route around any bias from VCs. Is this borne out in reality? Data anyone?
His example is unclear, but he's complaining about the behavior of conditionally casting the initial data values based on pattern matching.

<div id="test" data-foo="1.1">
$('#test').data('bar', '1.1');
typeof $('#test').data('foo'); // number
typeof $('#test').data('bar'); // string

If the data-foo value is user input, then converting it to a number might not be expected. E.g.

<div data-emoticon="0.0" />
Libraries make room for hackerspaces
I've been following this comment thread and I have to say that I find most of the argumentative and/or confrontational attitudes to be a direct result of your complaining. If you don't like Django that is fine. But don't expect others, who not only use but may also contribute and have a strong vested interest in it, to sit by idly while you trash their work and belittle the character of their community.
Great point. I'll implement that once I at back. Was originally just thinking about simple names, as this is just a personal tool. Thanks for the feedback!
Startups on a ship
If you wanted to implement something like this, regardless of merit, then DNS blocking is by far the worst way to go about doing it.

Anyone with an interest in using pirate sites will simply switch to alternate DNS providers, there will always be a way, and legitimate users will be subject to rampant and arbitrary censorship in the name of "stopping piracy".

You can't stop piracy. It's a supply and demand problem. It's a perception problem.

How can you convince someone that the TV show that is broadcast for free over the air is legal, but downloading exactly the same show at a later time is illegal?

Companies have all the tools they need to reduce piracy but they refuse to use them, instead trying to extort money from people through more conventional means. They'd rather have ten sales at $20 than thousands at $1.
I got it as well, in FF. Most of the time, these things get a one-strike-and-adios policy for me, but on this it seems important enough to try again later...

I agree that the effects won't be instant, and I too worry about the unpredictable chilling effects on the internet, free speech, and the U.S. technology industry. Like Robert Frost said, "for destruction ice is also great and would suffice."
So, if I'm reading this right, response time and reqs/second look pretty comparable between this and express.
In the comments, Brad Feld of Foundry Group said he prefers it to be last. Mark stated that this is a point of disagreement between them.
Out of curiosity, is there a particular downside to deriving them if the type permits it?
This method would have the immense benefit of turning a subjective "policy" into an objective algorithm, whereupon its direct impact could be measured numerically via simulations. As it stands, policy submissions are vague tomes of legal jargon with no measurable effects, coupled with a grandiose vision of implementation which is designed to elicit a positive emotional response from the electorate.
> it's not really "law" until it stands up to a test case in a court of law

This is not true. It is law until it's overturned.
Definitely not cheap, but still pretty cool. I like that, thanks.

I had been looking at stuff like this: http://www.scientificsonline.com/robotics/intermediate-robot...

but it seems so generic.
> On the money in bank question, you're looking for real money in the bank now.

Another way to put this: "can I see your current balance sheet and cashflow statement"?

Serves two purposes:

1. If they say yes, you get to see their actual assets and cash flow, unless they're flat out liars.

2. Whether they say yes or no, their degree of reluctance or acceptance is informative about managerial culture.
Also, there was something called "Faces" or "Picons" which were kind of a precursor to Gravatar which showed you images that corresponded to emails, domains, and more. Indiana University had a Web service for performing these lookups using finger[0] (looks like it has since been turned off). For example, here is Richard Stallman[1] and here is Dennis Ritchie (RIP)[2].

I don't understand this fascination with internet petitions. Hasn't it been demonstrated to the point of absurdity that our government does not care?

Before anyone claims "OH, so we should just do nothing instead????". Posting a dubious e-signature to an internet petition does nothing. There are people out in the streets sleeping in parks getting pepper sprayed and arrested because the government can't simply ignore it (unlike every single internet petition).

Filling out a whitehouse petition is like getting punched in the face by your boss then slipping a folded piece of paper into the complaint box he put in the break-room next to the donuts.
Personally I'd go to Singapore -- low personal taxes, no capital gains tax, no tax on income from dividends, low regulation, lots of capital, close to both Australia and Asia and it's a global flight hub.

The real problem is it's not just SOPA. This authoritarian trend has been going on since 9/11. The Patriot Act, Homeland Security, the Secure Fence Act, and recently NDAA, and PIPA. Each one is a clever euphemism design to conceal its true dystopian purpose. The American regime is strengthening itself to unprecedented levels... for what?

Generally countries do not strip its citizens of so many civil liberties unless there is a clear goal ahead. We will probably find out in the next few years.
Haha!! I remember /fingering/ Carmack back in the 90's... good times for all!
"The punishment doesn't fit the crime" is a turn of phrase.

If I see a parent kick a child because the child was annoying the parent and say, "the punishment doesn't fit the crime," is your first reaction, "BUT THAT CHILD WASN'T CONVICTED IN A COURT OF LAW! DON'T CALL IT A CRIME! RETRACT THAT STATEMENT IMMEDIATELY! PARSE ERROR!"

Also, you seem to be mistaking that I agree with 3-strikes laws due to my comment. The point of my comment was that the parroting of "The UN thinks the Internet is a human right," is wrong. If the UN really thought that the Internet was a human right, then every country that didn't supply free Internet to its citizens would be guilty of 'human rights violations.'
Everyone is mentioning how petitions don't work, which I agree with.

(Sidenote: I think it is an extra step worse that the government put up a website for petitions, and still ignores their own system. Random petitions (e.g. "\signed" forum posts) are one thing, but this is more like toying with people.)

That said, I think this petition has something important that other whitehouse.gov petitions don't: in that, under SOPA, there is actually technically a possibility that the government would censor itself (via whitehouse.gov), which is pretty funny if you think about it.

Edit: I suppose I mean "funny" in a darker sense.

I'd imagine you're unnecessarily polluting the type with unused functionality, no?

(not sure if this is true, perhaps GHC is smart about it).

If nothing else, superfluous derives would seem to distract/obfuscate your intent.
Jacques - I'm all for candor in discussions we have with candidates but in my view, this would be overreaching. I doubt most companies would be willing to show this unless they're hiring someone at the C-level. Plus for VC-backed startups, I wonder if there are limitations on showing this kind of stuff (we're revenue-backed so I can't comment on that)

I think your point #2 is valid even if you ask my initial question about "real money in the bank". If they don't know how much burn they have left or can't answer immediately or are reluctant, that is still a problem.
That was the first thing I thought when I saw this.

I tried starting a business my freshman year with a professor. The entire time my dad, a guy who has failed starting up businesses as many times as he has succeeded, just kept saying "Get the papers signed, get the papers signed, where are the papers, what are the numbers, how do you know he won't screw you over?" It went on for a couple of months until the professor finally cut me out. My dad had seen it coming from the very beginning and tried to tell me, but since I was young and smarter than him and gonna be really awesome early on in my life and and and and I ignored him.

I imagine some VC's are pretty much like the professor multiplied by like 50 million dollars of institutional money. Get the smart naive kids to make them money and then screw them out of the reward ASAP. (Other VC's are, of course, probably really awesome people who hate the reputation they have.)
I would love to be able to find the following information without seeming to be afraid of working hard:

"How often do you expect your employees to work extreme hours in order to be competitive in your company?"

If the culture of the company supports 60-80 hour weeks, it may not be apparent in a job interview... and even if it doesn't, asking this question incorrectly may paint you lazy or unwilling to put in time if(hopefully infrequently) necessary

At least that is how the "Zugangserschwerungsgesetz" in Germany works and I think SOPA
will be similar in this respect, but I might be wrong..

No, that's how the Zugangserschwerungsgesetz (access hindrance law) was supposed to work. But it didn't pass and the governemt abandoned it after a public debate.

Edit: ok, it turns out I'm misinformed. The law passed somehow after it was already dead, so it was never applied.

Germany was lucky that somehow it was achieved to make this law subject of public debate. Maybe Americans should copy the strategies that were used by German activists back in 2008 :) But on the other hand, I think that it would be a lot more difficult to achieve this in the American media environment. America's media was asleep when the Bush administration decided to invade Iraq, it will also be asleep this time.
I'm sure he's quite a bit older than me... here, Wikipedia says 1942 http://en.wikipedia.org/wiki/Dave_Cutler
If SOPA passes, every user-generated content website is going to have tremendous costs, in many cases prohibitive. I think only Facebook and a few players would have the resources to police their content. This is going to be really bad for Silicon Valley and the startup community.
I agree with you that ritual circumcision is dubious and I'd be happy to see everybody give it up (except when medically necessary, which happens sometimes), but am not persuaded that it's relevant to this discussion.

[...] it is considered a non-issue and discounted because of female privilege.

That is a statement you have not supported. For it to be true, there'd have to be some evidence that women generally were forcing it on men. Historically women couldn't force anything on men, and the people performing the operation were mohels and doctors, almost exclusively male.

I guess it's possible that there could have been some recent reversal in power, with women picking up pressure for circumcision and men slacking off. But I've seen not the slightest bit of evidence for this.

Given that, this seems like a typical "but what about meeeee" male response to a discussion of male privilege.
That's true, it was never applied and it was revoked on 1 December 2011. Nevertheless it was valid law for almost two years.
Just in terms of practicalities, isn't the health-insurance thing a much bigger issue for older would-be entrepreneurs? A healthy under-35-year-old can buy (sort-of) reasonably priced non-group health insurance, but I wouldn't want to be looking for it as a 50-year-old, especially with any sort of non-crystal-clear medical history.
