At least they teach you the maths of separable convolutions -

they don't teach you that the defualt opencv built with vs will clash with Qt libs built with mingw but the ing system won't tell you this!
Warning, spoiler?

My first take on it was the following:
Take the average of the differences between each pixel and the pixel adjacent to it over each column and store that as, say, X[].
Find some maximum number such that the sum of every nth column of X - the sum of all other rows of X is maximised. That's the column width.
Split into a series of columns, use stable matching to match columns based on the sum of differences between rightmost male pixel and leftmost female pixel over all rows.
Use stable marrage to give you a partial ordering, turn into a complete ordering and unscramble the image.

Any better/more elegant solutions?
being a chef is a hard job for sure but the real point here is that being on board for a succesful ipo is like a lottery win for all early employees. let them have it and enjoy it. don't make them feel like shit by telling them they don't deserve it. i don't see any win for zynga here
Now that, my friend, seems to be an actual challenge.
It's aimed towards those who are less code-savvy.
My understanding is that it's not permission from the user, but permission from Apple. If you need to do something outside of the sandbox, you need to go through their API calls. And when you submit your application, you need to justify each out-of-sandbox-API call you make.
It's called process substitution. In this case it runs the logger command, connects its input to a file in /dev/fd, and places the name of that file in the argument list of history. I've included a small demonstration below. This is useful since the history command won't write to standard out so you can't use a normal pipe. It's more common to see process substitution used to gather output from multiple commands, see http://www.linuxjournal.com/content/shell-process-redirectio...

$ cat writer.sh
#!/bin/bash
if [[ "$#" == 1 ]]; then
echo "Wrote to file named $1" > "$1"
else
echo "Wrote to stdout"
fi

$ ./writer.sh
Wrote to stdout

$ ./writer.sh | cat
Wrote to stdout

$ ./writer.sh >(cat)
Wrote to file named /dev/fd/63

Hi Jason, thanks for responding. I liked your post, and I appreciate that you didn't coin the term -- 'personal branding' has been around a long time.

But the idea of 'Public Rhetoric' has been around far longer, and that's what we're really talking about -- the connection between what I present in public speech or other forum, to a truth about myself -- the 'ethos' of rhetoric.

It's an ancient problem, and the concern I have with propagating the language of 'branding' is that it pulls it too close to the ethics of Mad Men for my taste. There are other ways to, ahem, spin this I think.

The intent of our public rhetoric should be more than just commerce or marketability, as you demonstrate with the charity you started at Stanford.

But I see a problem with the language of 'branding' so close to the idea of 'charity.' It raises a question of ethos -- why are you doing this? For self-promotion or for some other human good?

Of course this has always been a problem, and language can always be used to obscure our true motives. But declaring something as 'branding' outright seems to me to subtly give too much license to our more selfish intents. I'd rather we still talk about Speech or Rhetoric or Reputation than Branding, if for no other reason than it at least creates some distance between commerce and altruism.

And now I've taken this conversation into Aristotelian waters way outside my pay grade...
Just don't know how better to do this.. Apologize for breach of etiquette. Saw a post of yours about a month ago regarding Puppet vs Chef. Really impressed with your comments and wanted to dive deeper. Alas, the thread seems to have died and I cannot append or reply there. Is there any chance you would be willing to discuss that topic more? Many thanks in advance.

There is a series of known bugs where the window manager picks the wrong refresh rate resulting in choppy animations.

I noticed that this happens consistently with all compositing window managers (compiz, xfwm4, mutter) except kwin.

Disabling VBlank syncing may help. The bug report above has instructions to disable VBlank syncing with Compiz/Unity.

If you are using mutter (gnome-shell) you can put this line in /etc/environment, restarting your X session afterwards

export CLUTTER_VBLANK=none

However, in my experience, Unity/compiz becomes sluggish again after a certain amount of clients are displayed on any (virtual) desktop.
I agree that both open and closed can co-exist, but if media drives media (ie, advertising agencies chasing the app-for-no-reason bandwagon) how can we be sure that we don't have a monoculture in software development in the future? I don't think there is any argument that that would be an entirely bad thing.

At my job, I am embroiled in signs that point in this very loathsome direction.
Cloudability looks fantastic. How are they planning on charging? It looks completely free right now.
Seems like an awfully high price for something that would be fairly trivial to accomplish with an AutoHotKey script. I can appreciate the ease of downloading an app ready to go, but $99 seems really high.
Since he doesn't show the full URL in most of the images it's not possible to say for sure, but many of them appear to be a later stage in a multi-step process (registration, verifying email) to which you couldn't direct someone you wished to exploit.

If you have to enter bogus form input and make it to step 3, then while it technically is still XSS, it's not useful as an attack vector.

The others where an arbitrary user can be exploited by following a simple link (think I saw 2-3 of these) are real. CSRF protection won't help you there, since once I have JS running on your page I can insert iFrames or use XMLHTTP and read the CSRF tokens myself.
I guess the trick is to find the right problems to crowdsource.

Crowdsource that part, as well.
Thanks! Ping me if you do, I'd love to see it and be happy to provide some feedback.

What universe are you living in? The web sites/apps I use do all the things you describe, on desktop and mobile, excepting perhaps that most do not function offline (though the capability exists, the adoption rate is still low).

What's wrong with HTML being a compromise? Most things are compromises. What started off as hyper-linked rich text is a now a pretty-good (and completely open) software platform that really does work on just about any computing device there is, which would have seemed like a crazy pipe dream 20 years ago. What's the problem?
I would say this is a bad move that reduces competition, but the Big Four have been acting like a Big One for a while, conspiring together against us normal folk who like music.
Agreed, communication skills are important, trying to avoid communication with others about work-related topics, where they may need your input, is bound to get you labeled as "that guy" where people basically think you're a one-dimensional dweeb. Part of working within a team evnironment is learning the skill to handle some interruptions.
This. Attackers just point their attention to the greatest targets. When one target disappears, the attackers don't disappear - they just find a different approach. The recent iOS security breach proved this, in my opinion, pretty concretely.
Seconded. I showed a guy Ubuntu a bit back and it is now on his map and being used (not as primary, but it may be heading that way) because it has a start menu. He knows a tiny bit of linux (more like generic nix) and has interacted with various server solutions for fifteen years or so, but it's kind of "that thing you have to deal with" and most of the interaction involves calling me. That's ok, I'm mostly in charge of that. But Ubuntu now.. it has a start menu. And, like, through it you can find things. And they look familiar. Not all the way, but kinda. You can click them and they do stuff. He's actually finally getting into it a bit. He really, absurd as it may sound, would never have gotten anywhere if it looked exactly* like now, except with no start menu.
Stand up School Desks
As suggested on reddit, they all might belong to the same spammer. I don't know about hotmail account creation, but if it's protected by captchas only spammers have no problems making the accounts. Some captchas can be decoded in code with high success relatively quickly, others can be fed to mturk style services.

Google has phone verification now, I guess that's harder to overcome.
Ask HN: Anyone interested in Iranian startup culture?
I'm flying to Iran in approximately one week and spending about three months there -- possibly longer if I'm able to find work and land a work visa. I'd like to do some blogging if I can, and one of the facets I thought would be interesting to look at was startup culture. I don't know to what extent it exists, but what got me thinking about it was a video game released fairly recently called 'Garshasp.' Anyway, I wanted to see if there was any aspect in particular that HN readers would like to learn about, or even if anyone had any advice. Cheers.
So Ubuntu is for people who aren't willing to edit /boot/grub/menu.lst, but are willing to edit /etc/default/grub ? I've run (K)Ubuntu for six years, coming from Debian, and Slack before that. I don't want to tinker, and I'm not even that picky on my desktop environment as long as it looks reasonably good and I can setup some hotkeys. But any distribution has to be serviceable, or you wind up with MS Windows where the fix for all problems is forum folklore, and failing that, reinstall.

And furthermore, why would I recommend Ubuntu to new users knowing that I'm not going to be able to help them as easily? A bit of an exaggeration right now, but an inevitable result of the path Ubuntu is on. A user friendly distribution should work with existing conventions, not discard them by creating a whole new layer on top.
For those wanting to solve the problem another way, see: http://skeptu.com/secure-alternatives-to-dropbox
I find it strange that they don't provide an interface that the desired program should implement. For example, "provide the input image as a command line parameter to the script / binary, write the output to out.jpg"

Because of this, is someone going to actually take the time to understand what assumptions people make to run the program? If there was an interface, they could just run a script to test submissions...
Wow. I knew the labels' economic relevance was declining, but I'm amazed that one of the four key "factories" in the commercial music industry just changed hands for $1.9 billion - less than half of Dropbox's recent valuation.
Nonsense.

Options are negotiated at the time of employment for a reason - their value is derived from the risk and their upside. You cannot go back and take them away "because they're worth too much". It defeats the purpose of having them in the first place. If you want to cap the value, do it at the time of the agreement. Otherwise you are misrepresenting the value of the compensation.

As long as the employee is doing what they are supposed to be doning (and if they're not, they should be fired), those options should be paid out, regardless of their worth.

Ask yourself this: What would Pincus be doing if those employees had worthless options? Do you think he'd be writing checks to cover their non-gains?

I know the agreements are written to allow this behavior. It's still wrong, and goes against the spirt of equity grants.

OK, fair enough.

But, ethics and nuance aside, I do think the implications in the long run, esp for founders and entrepreneurs who actually need the 'Google Chef' story, will be a simplistic account in the minds of developers that will make it harder to recruit them.
And if KDE 4 isn't for you there's also Trinity's KDE 3.5 remix (my preference).

Lot's of options out there.
Seems to me that in a meritocracy, if executives give away stock in excess of what is required, they are the ones who have performed poorly.
I probably would not go to college again and would just study on my own or take shorter programs (ie. 2-year degree)

If I did go again, this is what I would change:

While in college, after the first year, I spent more of my time working on extracurricular activities than on classwork. The classwork was mostly boring and not very practical while I learned much more on the extracurricular stuff. I would still do that.

I did take some classes not related to Comp Sci and don't think they really helped and were just a waste of money.

I left college with $35k in student loan debt and would try to avoid debt or take on much less.

I would have gotten part-time/summer work related to programming instead of irrelevant part-time jobs.
> YC is an amazing opportunity to work with some of the finest people in the technology industry, it’s not a ticket to automatic success

Find something you are passionate about, work hard, be persistent, and go for it. YC is a great opportunity, and you should be looking for opportunities whenever you can.

But without your own hard work your company will be nothing, and this doesn't change with or without YC.

Yes, it sucks getting rejected from anything, but the only time it's the end of the world is if you give up because of it. My last startup that interviewed at YC, was rejected, and shut down soon after, probably weighed too heavily our rejection (though it was far from the only reason we shut down).

(Disclaimer: I'm a two time rejected applicant, one time rejected interviewee)
This is a pretty amazing story. Thanks for sharing! I wasn't inspired by this when I wrote it up, but it looks like it's not the first time it's crossed someone's mind.
No difference in the programming model, perhaps, but the internals are very different.
Clarifications on Flash Player for Mobile Browsers and the Future of Flash
A preview of Khan Academy's CompSci editor by John Resig
Why not run Ubuntu classic on 11.10, which uses a very polished Gnome 2 shell?
Not sure why I keep posting Flash related stories. Maybe it's a morbid nostalgia for the days that I did Flash dev work. Still interesting.
Most systems are implemented poorly. However, even even with encryption as long as you don't authenticate with an online server somewhere once you have physical access to the device is almost impossible to prevent someone from copying the internal key's. You might end up producing 50,000 identical devices that are easy to track after the fact but they can be sold before those defects are noticed at which point they can just swap to the next set of key's.

Worse yet most 'secure' RFID systems just retransmit the same key every time and trust repeated use to be detected by other systems.
You could have tried Ubuntu classic.
I wonder if she ever married the Baron.

Even in scenario B, for most of the '90s and early '00s, a Windows-based PC was the presumed default platform. If you said "I want to buy a computer", it would normally be assumed that you meant Wintel. Scenario A, was, until relatively recently, only meaningful for very specific application categories: if you did DTP, you might buy a Mac, if you did video editing, you'd use an Amiga, and if you did research, you'd get a Unix workstation.

But almost all non-specialist applications, and even most specialist software, was targeted to the DOS/Windows platform, leaving most developers just as much in control of their destiny as in the earlier iteration of scenario A, if not moreso, since they didn't have to expend capital porting their products to a half dozen different platforms and gamble on which platforms would survive.

Platform vendors successfully 'commoditizing their complements' is a very new phenomenon, and one that's attributable to the vendors integrating their own distribution channels into the platform.

Scenario C may be helpful for developers' independence, but desktop/native applications aren't going anywhere in the short term, and the threat of Scenario D - the web itself becoming a more closed, regulated platform due to the influence of Google/Facebook/etc. - still looms on the horizon.

What might be helpful is an open, distributed software sales channel that can compete with the various proprietary app-stores across multiple platforms. Content retail needs to become a protocol, not a place. But this is probably a relatively easy technical project and a tremendous marketing challenge.
Yeah I'll buy that.

...oops
Given that most equity is worth nothing in the end I don't think you're correct. The beautiful thing about equity is that its future value can not be determined and it's not possible to limit the upside fairly. If employers start putting a cap on the upside, it undermines the shoot-for-the-moon lets make this a $100 billion dollar company spirit that equity otherwise engenders. Had Google had a $1B exit, or a $100M exit - both far more likely scenarios when the chef joined - the grant would have seemed perfectly reason.

This has nothing to do with risk and all to do with incentive. Whether your grant is on top of a full salary or not is irrelevant.

I still do the same for almost all CRTs. I'm pretty young though. The most annoying was waiting for the ACT to start while hearing a loud super high-pitch electronic whine went on every five seconds.
The throwaway paragraph about fashion holds much truth, I have found. I decided a year ago to learn how that stuff works. I can't even begin to list the benefits that come with it - it isn't only women that like you more, but men are more likely to take you seriously if you aren't walking around in jeans and a t shirt.

Here's a good site to get started:

Lots of good advice, I agree with most of it. A more important step is to head to a high-end clothing store, the type that sticks a salesperson on everyone who walks through the door. Yes, the clothing is expensive, but in conjunction with the professional advice it is very much worth it.
Why Buy Silver - Buying Silver In Times of Crisis
Personally, I think it has more to do with the fact that very few people want to fix old bugs in an old codebase in their free time when they could be writing a brand new version with brand new bugs. "This time, we'll make better bugs!"

Yes, a very large part of it comes from Ricardo. However, theory before Krugman was mostly limited to belief that the main gain from globalization was from trade between countries with capital and those with cheap labour.

Krugman took it one step (actually there was even more people in between pushing the theory forward, as Hecksher and Ohlin) further and his point was that economies of scale will make it beneficial also for economies of similar development level to trade with each other.

That's been mentioned a few times, someone even said four big tech companies (e,g. Apple Google Facebook and Microsoft) should just buy one each and cross-licence, the customers would love that.
Just wondering, were you rejected twice after being interviewed the first time? I'm wondering if they will dismiss you more easily after having met and decided you aren't the type of person they want to fund...

it isn't only FDA per.se. The financial aspects of biomedical R&D is very peculiar. Different time - first half of 199x, different country - recently post-Soviet Russia, different scale of money ... i was involved in the project to secure financing (high tens of thousands of dollars, the project would have become profitable at the 3rd, possibly 2nd year - too long of a shot in the environment where trading in metals, vodka or electronics would bring 50-100% scale profits on the first turnaround, ie. on weeks, rare few months, time scale) for productization of some wonderful technology developed by a leading brain science institution. Well, we failed.

These days, with all the supposed and expected high/bio-tech boom and the marvelous advancements just around the corner, we see biotech layoffs, and a couple of PhD degreed with years of experience biomedical professionals i personally know here in the Valley can't get a job even at half what i'm making in the software. One of the reasons of such a state is that financing of the industry requires bigger scale, amount- and time-wise, of money, and thus is coming from banks and other institutions who have significantly decreased imnvestments following 2008. Talking about stimulus and the dirty cheap Federal money the banks have access to - it just isn't trickling down as lazily pumping the money though treasuries and QEs is much more safe way to profit from the money.
Bingo! You summed up humanity in 1 sentence.
