Databases. Oracle, Microsoft, etc. have figured out a lot about how to make high-performance query execution engines and transactional storage systems and written about very little of it. Research has caught up some, but it definitely lags.

There is a difference between being somewhat edgy and improper ("no bullshit") and actively working against one's aims by including copy that is confrontational and discouraging to the most insecure segment of one's audience ("you have a ma

Pricing based on cost (with fixed "this is a fair amount of profit") is a terrible pricing scheme. patio11 talks about this a lot. Here's a podcast where he talked about it (more in the context of B2B software, but many principles still app

Assuming you're interested in even compensating yourself for the time you're spending on this, I wouldn't go too low. Maybe base price of $19, and free when you order the physical book? That would still give you some wiggle room to do sales

I would adjust the tone for the "I am in Arts" section. Saying "I think you have math issues" is not the kind of welcome you want to give to people who do, in fact, have math issues. I like the end, where you emphasize that math is a great

Given that mobile photo sharing has been done to death, I'd be interested to hear what you think makes Pixit a significantly better solution than all the other apps out there for some usecase. (Not trying to sound confrontational--it's just

Exactly. We have representatives for good reasons. Almost no one cares about most bills (which means they also won't know all the intricacies that often make the difference between a good bill and a bad bill). Even with the high-profile one

For now they really only saved $300k/yr, which is less than the cost of two engineers. Though I guess cutting a nontrivial expense that is likely to grow by nearly a factor of three is pretty great and probably worth investing in. That said

GitHub's failover problems have never been load-related. GitHub has pairs of fileservers where one is the master and the other's sole job is to follow along with the master and take over if it thinks the master is down, so when they do fail

I doubt it. (Assuming by 2 digits you mean < 99.0%, ie that they don't have "two nines" (though I guess two nines could even be 98.5 with rounding)). 1% downtime is over three days. They've had some big outages, but I think this may be

Cloudera Impala uses LLVM to generate code optimized for the specific query it is running (basically compiling away all the generalness around how large records are, etc). Some kind of native code generation is apparently standard practice

If they were to actually exploit their possession of the information (eg. get credit in the person's name by piecing together confetti with name, DOB, and SSN), it would be a crime. The tricky thing is that with hacking, the line between pi

Don't put so much stock in an online dating algorithm. He was just trying to illustrate how perfect everything seemed, how sure of everything he was, until suddenly that stable-seeming foundation fell out from under him. There's no way that

Those are very different problems. Cell-phone carriers have formed an oligopoly due to the extremely high cost of building nationwide service and the limited amount of mobile spectrum. This will naturally lead to a situation where the indus

My HTC Droid Incredible's browser also always complained about their certificate and popped up a dialog box I had to click through. But now that I've installed Cyanogen Mod, it hasn't been a problem, so I guess it's one of several things HT

His point is that there's no great time to announce layoffs, and it's perfectly acceptable to announce it or any other bad news at a time when it will get the minimum media attention. Everyone does it, and it's in the best interest of the c

Agreed. I think the actual reason, in this case, is that Stanford isn't sure it's comfortable putting courses on a private company's platform in the long run. So they've made the strategic decision to hire a team and build their own platfor

Can anyone explain why a log-structured file system is a good fit for flash? It seems that a lot of the benefits of an LFS are that it reduces disk seeks.

The bullet trains make it ~40 min SF->PA, ~45 to mountain view. There's lots of companies in downtown PA and MTV, making it just a 5 minute walk on that end. You also might have an easier time if you live near BART (say, in the Mission)

It's still not perfect. I had a ThinkPad T520 this summer for work with 11.04. This is one of the highest quality ThinkPads. To make Unity and the DisplayPort port (as opposed to just VGA) work, I had to go into the BIOS and change a graphi

Oh wow, I didn't know what it used to be. I heard a couple people who liked it last year (McKeown was one of 3 teaching it). It sounded like it wasn't all lit review (unlike 240, which had literally nothing but paper discussion). They had s

The problem is that the DX is not a good Kindle from Amazon's perspective . Note that while you're requesting your "printed page" to be printed page size, they're focusing on a "book" that is book sized. From Amazon's perspective, a great

I don't think raising early increases the chance of that company going for a talent acquisition at all. Just one example: I work for Cloudera. As I understand it, we raised a fairly large round when we had almost no employees or revenue, an
