Or just pull my old Ubuntu box out of the closet. No webcam, no mic, no problem. Still, this is hilarious because only the truly desperate will put up with this crap, everyone else will just get their jobs somewhere else.

I can see why they might do this, anyone that can land a job with similar benefits somewhere else probably doesn't even apply, leaving them with the worst to choose from. Their climate gets even tougher because they "can't hi

Maybe I was a hit too excited about the perl part. Perl perfected regex and the perl regex engine was integrated into other languages until it became a normal language feature. Regex as we know it was largely a result of the adoption of per

I think node is the funniest example. "Yay we can run js on the server now! This is the future!" But wait, what other language can't you run on the server? I can't think of a popular language in existence before js to ta

I'm in the opposite camp, it feels like js is mutating quickly to try to fix the rediculous problems with the language because people are forced to use it. You don't see such sweeping changes in other languages that have been arou

I donno man, the longer I use typed languages the more I hate untyped ones, if only for the IDE help alone. All the newer static languages use type inference anyways so its not that common to need to specify explicitly. Besides, if you want

I see the proliferation of JavaScript tools as a massive failure of the vanilla js standard library and ECMA. Most of the stuff out there just rebuilds basic language features that would be standard in other languages. We wouldn't need

Fun factoid most have forgotten: regex is perl. The beginnings are elsewhere but regex as we know it was designed as part of the language and the engine was pulled out and reused when people found how useful it was. Perls regex parser is st

I have heard whispers of this, and the mention of common on call hours seems to lend it some credibility

The failure mode doesn't matter much in practice. You need to track how many inserts you've done on both for practical reasons so with either you'll have a set cutoff before rebuild. Cuckoo filters are more likely to be used

What makes these so easy to detect that they're this secretive about it? There has to be obvious clues in the TCP/IP stack. 4g modems are opaque and proprietary so it's unlikely the fear of discovery lies there. If I had to g

The net effect is much larger than the smallish overall effect appears to be. The request is much smaller and this has a surprisingly large effect because modern consumer connections are asymmetrical as much as 20/1. Those requests tak

Http was not designed for what we're using it for. The biggest problem is numerous requests, which is caused by http using TCP underneath, not by multiple requests in themselves being bad. Bundling is not a best practice because anythi

To add to this, you can buy GPS time source dongles really cheap and in Linux it's not too hard to run one as a parallel/backup time source. Especially when using distributed databases where write priority is determined by timesta

My biggest issue with NTP is little control over who runs the servers. Unlike the CA system that has checks in place against bad actors, practically anyone can run an NTP pool. It was discovered a while ago for example that some part of the

Have you looked at Siphash? I remember reading recently that murmur has been found to have some predictable hashes independent of salts but a lot of big names still use it since it's fast and has good properties.

Okay thanks, that explains the why but doesn't make it sound less terrible. They essentially built a nosql database on top of MySQL. Forgivable years ago but this was in 2014...

Nothing hard but the various leaks of diplomatic cables and spy tools have made claims of state sponsored hacking undeniable. Everyone knows that all the big companies are getting hacked all the time thanks to the leaks. How is a technical

It's gotta be the case. Probably choose trip db based on cutting map into squares or hexagons. Dump all location data from drivers and riders into it real time. Sounds like they've got batch jobs running against these databases to

Is it not cool to call these things worker threads anymore? Nothing wrong with the article but I'm getting annoyed by the trend to rename constructs and common patterns in new languages. Wasting time learning about Y in language B only

It sounds like Uber has a database cluster for roughly every employee?!! Uber has a single product that largely centers around 1 app. How can this be necessary? I have a feeling... That they're dumping realtime GPS data into a bunch o

True. Even very successful database projects in Java have some issues with GC pauses. Go seems to be, IMO, taking the things Java is best at and trying to make something better. Basically, how would you build Java today if you could do it a

Companies have always shifted blame. I think there's just less disadvantage to admitting you were hacked than there used to be. Companies used to keep that stuff under wraps to avoid looking weak, but it's so common now that it do

Verilog does exactly this. You design the logic than simulate all the gates. I'm sure there's some open cores out there ready for simulation if someone wants to fiddle with it

Http2 fixes the speed issue and generally requires HTTPS, Eventually all http will be encrypted. Unfortunately some big names are dragging their feet implelenting http2 in servers, even though most clients already support it.
