Naming is hard, no question. Context helps, though. In realm where I live, computer science, x, y, and z likely correspond to something in the problem domain, like "rate" or "time". And even if we're dealing in pure

There may be occasions when a single letter makes sense, but this should be the exception, not the rule. If you've got a ton of "anything" variables in your code, then that means there's probably a better, more understan

But that's not our experience in software. We do write "learningRate" over and over again, because we've learned that that makes the code much more understandable that just writing "e". In fact, we've le

I'm a software developer. I need to understand computer science papers to get my work done. I've studied enough. High school and several courses in college. Enough that I should be able to take it from here and learn on my own.

This article starts to get at an idea that I've had for a while now -- that mathematicians are doing it wrong. In the software business we learned a long time ago to name our variables properly, name our functions logically, and to con

This is a big deal. We've always made a distinction between memory and disk. Much of computer science is about algorithms that recognize the difference between slow, persistent disk and fast, volatile RAM and account for it somehow. Wh

Yes. Light travels 839 km or 521 miles in 2.8 ms. If you need a round-trip to send a query and get a response, then you would have to be within a few hundred miles of the datacenter, assuming perfect efficiency.

You might consider removing the badge on the home page that says "Global Latency 2.8 ms". Unless you really can give me latency across the globe of 2.8 ms, in which case your solution to the speed-of-light problem is quite impress

Have you published the software anywhere? Do you have an open source implementation? (The Elastifile Github account doesn't appear to have one.)

My thought exactly. The article doesn't give any numbers on how many customers, messages, "tribes", queries per sec, or anything. This market just doesn't sound very big, and it's probable that a plain old CRUD app

Completely agree. I wrote code in Delphi 20 years ago, and I was far more productive than I am today. The secret was to have self-contained components that fit within a rigid layout system. It wasn't easy to make things pretty, but it

We have an Overton window here on HN. It's enforced through downvoting. I would very much like to see downvoting eliminated, or at least modified so that a small number of upvotes can counteract it. There are a number of perfectly reas

Thank you. "Postings" is another word for the format of the doc ids and related information in the inverted file. A google for "inverted index postings" will turn up a bunch of references.

You get really good performance on not much hardware. Can you share some technical details? - file formats, particularly the postings - query evaluation strategy - update strategy I poked around in the source code a bit, but couldn't f

There are really two villains here, Mylan, of course, but more importantly, the FDA. FDA regulations make the cost of bringing a new medical device to the market absurd. There are no competitors because the time and effort to bring a compet

Can someone explain what "criminal defamation" is? Is that even a thing? In what circumstances is it a crime to defame someone, and not merely a cause of action in a civil suit?

Perhaps. But the fact that they used a remote-controlled device is significant. It's quantum change in tactics for the police. It gives police far greater powers against suspects. How long before they use drones to shoot suspects? What
