(GazeHawk intern here.) That's definitely a good approach if you presuppose the existence/obviousness of distinct page elements, which is a whole beast in and of itself.

Right now we allow our customers to define "Areas of Interest" in our reporting system, and we immediately display statistics like average user time on area, average rank of area (ie how many other areas, on average, did users look at first) and so forth. However, it's unclear to me how to represent these numbers in a visually intuitive way in the case where there are 50 distinct areas.

One possibility we're exploring is coloring different areas with different intensities based on some index composed of these features. However, it's not clear what the right formula for this index is, or if it's the same in all situations.
Diverting investors' capital from the startup they picked into another startup providing B2B services would be a legitimate concern. But is this actually happening enough to even move the needle for YC? Their past or most likely successes off the top of my head have been Reddit, Dropbox, and the AirBnB spammers, all of which are primarily B2C and don't have other YC startups as major clients. I also wouldn't expect any viable startup to live or die by their prominence on HN; this audience is still small and mostly frugal, more likely than anyone else to conclude (sometimes falsely) "I don't need to pay for that, I can build it myself". This isn't very convincing even before the 20 IQ point penalty for encoding a page of text as a 72 KB image.

Edit: there's a longer greatest-hits list at http://www.crunchbase.com/company/y-combinator, and none of those look like major money sinks for other YC startups either.

1) Make sure your personalities meld - I hired people multiple times for their coding chops when we didn't necessarily 'jive' and it made working with them over a long period pretty painful, especially when brainstorming or doing stuff like critique

2) Make a test with problems unique to your space - aka if you write scheduling software, have the test use some date/time functions or if you write a search engine have them write a simple DOM tree parser. Nothing crazy complicated, but enough to give you an idea of what they are made of. Let them take the test home to complete, then give them feedback about their answers after they return it and see if/what changes they make in response to your feedback. This gives you a good idea if they are willing to adapt and learn in your problem space, and if they can take constructive feedback.
I see the block at the end as "

A few conclusions:
"/* is more prevalent than "/. Yet anecdotally developers use "/ more, and in practice most schemes are protocols.
"/* is used consistently (to mean the same thing) as are "/* and "/.
"/ has been used consistently for the past 10+ years and in a way consistent with its operating system roots.
"/* is used inconsistently as to whether or not it includes the leading "#" hash/pound symbol. However, notably absent from any specification or platform was the alternative phrase "/*.

"

I haven't read it, but from skimming it looks like the tactic is to follow consistent rules for the entire course. The system being built is entirely self-contained, just complete. This makes it a lot easier to build on what you've already done.

In a typical csci curriculum each class will start with its own set of assumptions about which systems are being dealt with and what tools you need to learn. You might take a compilers class that uses yacc, a languages class that uses Common Lisp, an OS class that uses Java and an architecture class that uses x86 assembly. For each class you'll need to spend some time reviewing the tools and systems specific to that class, in addition to spending time on theory that isn't relevant to the focused goal of building a working computer system from scratch.

Combining Message Authentication and Encryption
If you can map all VM registers to CPU registers, the interpreter will be way simpler.

If you have more VM registers than CPU registers, you have to write code to load and store your VM registers.

If you have more CPU registers than VM registers, you will have to write code to undo some of the register spilling done by the compiler (if you want your VM to use the hardware to the fullest.)

So, the optimum (from a viewpoint of 'makes implementation easier') depends on the target architecture.

Of course, a generic VM cannot know how many registers (and what kinds; uniform register files are not universally present) the target CPU will have.

That is a reason that choosing either zero (i.e. a stack machine) or infinitely many (i.e. SSA) are popular choices fo VMs: for the first, you know for sure your target will not have fewer registers than your VM, for the second, that it will not have more.

If you choose any other number of VM registers, a fast generic VM will have to handle both cases.

Alternatively, of course, one can target a specific architecture, and have the VM be fairly close to the target; Google's NaCl is (was? I think they changed things a bit) an extreme example. I have not checked the code, but this, I think, is similar.
Optin App Review
Indeed. Compare the razer to Alienware's comparable offering, the m17x: http://www.thelaptopauthority.com/image/m17x.jpg

The Razer Blade may be a fairly blatant MBP ripoff, but at least it looks good. Alienware seems to be pursuing the clunky F117-inspired look, complete with superfluous LEDs. This is, unfortunately, not unique to Alienware. Asus teamed up with Lamborghini to offer the VX7: http://rumors.automobilemag.com/files/2011/04/asus-vx7-lambo...

Lamborghini makes beautiful cars, but I'm not keen on plopping one on my desk in the middle of class. The Razer looks like something I'd actually feel good about being seen with.
Definitely would be difficult...but pride and admission of being wrong would be a horrible reason for not changing course.
I guess my first question is where is the proof? This looks like utter bullshit, but I would be much more interested in it if there were sources to serious compiled raw data that proved this in any form.

Don't listen to claims and made up facts.
And, in fact, they even say so.

> The lectures, book chapters and projects are highly modular and one can pursue subsets of them in any order and scope.

From the course's site's about page: http://www1.idc.ac.il/tecs/about.html
damn, please someone tell me this is photoshop.
Please allow me to address the "4 critical-difference-making components."

1- Shell - I love the idea of having a gaming laptop with apple's build quality, but its hard to fit a decent GPU and cooling system in such a slim, stylish case. Gamers know this and are generally willing to compromise. While I hate the way alienware computers look, many reviewers gush about their excellent build quality.

2.-Battery - High-end GPUs use a lot of power. Unfortunately, current technology only allows for the battery to act as a glorified UPS. This is unfortunate but anyone who is purchasing a gaming computer should understand the limitations of such hardware.

3.-The keyboard is very important. Alienware keyboards aren't the very best keyboards, but they are better than the overwhelming majority. On the other hand the Razer has a "chiclet" keyboard which is considered by many to be inferior to traditional laptop keyboards.

4.-The LCD - If you purchased a gaming computer, would you rather play a game at 17 FPS on a beautiful screen or play the same game at 60 FPS on a computer possessing a marginally worse panel.

When you are talking about a gaming computer, the GPU is pretty much the only thing that matters. If you want battery power, a nice shell, and a nice LCD you can get a SAMSUNG laptop with the same specs as the Razer for 2k cheaper.
The secret of schmoozing is that you don't have to. When you don't really have anything to say (in a particular context), but try too hard to, it almost never works out. It's a better choice to find another context -- one that does engage you.

If you're stuck where you are for a while, or you find it interesting, just listen. Most people appreciate a good listener -- often superficially, sometimes deeply.

A neat trick would be to overwrite the original details (such as email subject) with something like "Did you really think you could unblur this?" in an identical font. With a security company, whose followers probably enjoy puzzles, you could go a step further and make a game out of it. For example, the unblurred text could contain a URL for a microsite that has a little game related to one of their products. It'd be fun and promotional at the same time.

The downside is that this trains people to always try unblurring your blurred text and almost guarantees someone will find the one instance where somebody forgets to blur something.
500 actually. I got it a little while ago. That's comments only.
Nice subtle snark.

There might not be a lot of power in the Air but there is a market. Specifically, for people where mobility is more important than power, but able to get actual work done.

I bought one when I was hauling around my ThinkPad to school, work, coffeeshops, and everywhere else around the city. Since I didn't have a car, it meant it was one my shoulders the whole time. I considered getting a netbook, but after using a friend's for a little while, I realized it wasn't going to work (tiny keyboard, not enough power.)

The Air, on the other hand, has a full-size keyboard. I don't remember what the processor is, but it was more powerful than an Atom. RAM was short but you can survive.

I used it for primarily writing my thesis, making presentations, coding in TextMate, and work in Matlab. I didn't need power, and I definitely didn't want weight. That was lighter and easier to hold than a textbook, and could actually perform the duties I needed to.

So, regardless of what you'd like to think, there is a market for them outside of people who want shiny things.
Can we please not have this on HN? Flagging this now.
Thanks for the insight. I think most people want to do the "right" thing. The competition to be "THE" way people play media was very intense between Real, Microsoft, and Apple. There was a lot of trickery on all sides uninstalling other people's players, making them not the default, etc.

Too bad this all devolved so terribly and not in the direction of the best experience for users.

I struggled for days trying to get my openID working like it was on stackoverflow.com, and I finally gave up. The amusing thing is, I subscribed to that thread via email, and every few weeks, there would be another pissed off commenter who wondered why it wasn't working.

Does your openID require setting up a local account (with username/password) still?
This is a great book, but each of the sections are very short introductions to the topics. You dig in and actually build something, but not anywhere the same depth you would in a course dedicated to the topic. (And I didn't feel like the operating systems section was really worth it - so cursory.)

This is only true for objects that have a spherically symmetrical mass distribution and for a point test object. That is, the field of a spherically symmetric object is the same as the field of a point mass of its mass located at its center.

As soon as your test object is non-point you get tidal forces due to the field typically being nonuniform. As soon as your object is not spherically symmetric you get a field that looks nothing like that of a point mass.
I enjoyed your comment, but will downvote you because I was downvoted when doing similar jokes.
One I can think of now: It doesn't tell you when someone with prior versions of the OS tries to download something you built with too high of a deployment target. This happens so often right now with the Verizon iPhone versioning being <4.3.
If the OP were being asked out on a date, I could say with 99% condfidence it was because of his looks. If he's getting job offers, from presumably (just going with the odds) heterosexual men, then I strongly suspect there are other factors at play besides just how he looks, regardless of the ethnicity of the person perceiving those looks.

You have a plastic that states first class country living rights to any woman that get's you. Living in China for some time you didn't realise the "attractiveness" of that? I tell you something. I saw a 50 year old, objectively ugly, stupid US guy in Hangzhou who most people wouldn't waste a 'hi' on. But Chinese girls were running after him, telling him how attractive he was. You still think you are so handsome because Chinese girls tell you?

I mean, what should they say? "Marry me, because then I can live in Meiguo." (for them it's not a big difference) Also I can't blame them to want to improve their living conditions. Their live really sucks and it seems (not sure, was there just for one year) that life really is harder for women there, then for men. Don't be naive. At least know what really makes you attractive, over there.
ActiveState adds Python & Django support to CloudFoundry
He is an angel investor in media and e-commerce companies.

I wonder if he has invested (or plans to invest) in Facebook? Full disclosure would be nice.

Next year, search advertising will be a $15 billion market in the U.S. alone, growing by 14 percent, according to eMarketer. And, if Facebook can capture half the share of that market that Google has today, it could easily add an extra $25 billion or even far more to its value.

Is it just me or does the math not add up. If search advertising is $15B next year, how can Facebook add $25B of value if it takes 50% of the market share? I assume he means globally (versus the $15B residing in the US alone), but with those kinds of numbers, he's got to back it up somehow otherwise he's just pulling them out of the air.

The key to be more creative
Atari 2600's Halo source code
1. Save files.
2. Targeted ads
3. To get a unique identifier for the phone. (I.e. ads again)

Number 3 is an example of Android permissions being insufficiently granular. It's nice that you know when installing apps that they can get a unique identifier (which until iOS5, apps always had access to on iOS. It's randomised or something on iOS5), but its also a nuisance that it requires giving other permissions too.

Number 2 and number 3 are arguments for being able to refuse apps permissions like you can do with iOS location settings.

It simply is a matter of concerns. Ideally, your model should represent the state of your application, it doesn't matter if an event needs to travel one or more layers in order for that to happen.
Views may very well be a representation of the model.

It's obvious that FB would want to enter the search market, and the post doesn't even mention the biggest reason: search ads are more valuable than social ads.

And I think the obvious reason for that is: Ads on a social network are basically spam. They're explicitly trying to distract you from what you're doing. Search ads augment your search and harness your intent. Google gives you things you might actually be looking for when you're looking for it.[1]

And also, I don't think social search is as important as people think. The whole point of harnessing the power of the entire web for search results is getting stuff that we didn't have access to before the internet. I've always been able to ask my friends their opinion. The web lets me ask experts on the specific subject at hand.

Why wouldn't FB want to do this? Because FB doesn't really want to send people away. They never have. Everything they do is designed to keep you on the site, and their external stuff is designed to draw you in.

Also, it's super hard (which the post does mention). Which makes me think it's way more likely that Google will eat FB's lunch than the other way around. Seems to me that Google already has a lot of FB's tech/infrastructure built, while FB has much less of Google's.

How Programmers Get Rich (Time Magazine article from 1982)
I read a comment from pg once that he "grades" flags based on how many articles you flag that actually do end up being killed. So it stands to reason that if you only flag honest-to-god spam, which almost always gets killed, then you'll get a high "grade" for your flags. But if you flag stuff that you think is merely off-topic, that mostly does not get killed, it just languishes with low points. So those flags would be counted against you. I of course have no inside knowledge about this. He may have changed the code since then.

For what it's worth, I go through /newest about once a day and flag only honest-to-god spam, typically three or four at a time. I've been doing this for a couple of years now, and I can still flag stuff.
