Also useful: "man iso-8859-1" (aka latin-1, the most common Western charset if not using UTF-8). For the Windows version, you'll have to visit http://en.wikipedia.org/wiki/Windows-1252 -- non-UTF encoded

Seccomp might be a possibility here, but will require one process per live robot (and Linux). With seccomp your process can do nothing but read/write from its file descriptors (so you have to make sure they are safe) but can do nothing

I flagged it because it's just not interesting. Where's the "hacker news" angle? That a company's community representatives should never remove posts? That Lawrence Lessig should somehow enjoy immunity from what the

I believe the "approximate computing" (also "inexact computing" or "soft computing") to be one area. Computers always do exactly what you tell them, but that correctness is resource intensive. With the "ap

The forum sends back a simple preformatted chunk of HTML which is then inserted at a certain spot. It does not send a complex JSON object that is then marshalled into some kind of Angular-Knockout-Backbone framework of the day where complex

None of the ideas in YYY are new. It's a mundane and vulgar rehash of things we already had in the ZZZ in 80s but done badly. OK, so the world's largest sites run YYY -- that's pure luck, not science. Or the fault corporate H

I was hit by the transparent huge pages on RHEL 6.2 in my workload. If you find our ordinary processes randomly taking up huge amounts of CPU time -- system CPU time -- when doing apparently ordinary tasks, you might be affected too. That w

Don't forget the ordinary UNIX domain socket: you can think of them like TCP connections bound to 127.0.0.1 but not assigned a port number but a path name. This can be useful if you have e.g. 3 instances of the same program that needs

Here's an Evil Idea for a open source equivalent: foss-testing.org. Innocuous name, but it chains together user identities with checkins they've made that were 1) style violations 2) turned out to be bugs 3) turned out to be later

One interesting LESS feature I found when we were evaluating it for letting some users use it for customization: it can evaluate arbitrary Javascript and open and embed files. Just in case you thought it was some pure transformative shortha

If you want to version control a single file locally with no fuss (exactly one file,v file for storing changesets), I could still see it being handy. It seems it has a maintainer that is very inclusive and accepts all portability fixes. Whi

There WAS such an issue generally with PHP installed as CGI: a query arg like ?-s would be passed as a command line -s switch to the PHP interpreter spawned. http://www.php-security.net/archives/9-New-PHP-CGI-exploit-C.

Well, using DataDog I can 1) increase a counter when something happens -- like an error or an expected user action and 2) setup an alert when the average amount of events over a X minute period is sustained above or below a certain threshol

Over the last decade, there's probably been half a dozen "standard" command line parsing tools. getopt being the classic, then we had optparse and that got deprecated, then we got argparse. And there there's e.g. twisted

Well, It's a multi-threaded program, and when you create a project it will start out by indexing everything. So while it's doing that, it can spend quite a lot of CPU time -- "top" etc. typically show the CPU time spent

The SLA isn't really great (but that's not exclusive to RS). For RS managed hosting SLA 30 minutes of network downtime means 5% of monthly fee back. So if this counted as downtime (and that's unlikely) and your email was down

I dump my JSON as YAML. Even if you are not using YAML for saving data (and I don't -- in Python at least PyYAML is orders of magnitudes slower than the built-in JSON), it is nicer to read.

So to be clear: 1) The attacker must be on the same network as you, or at least be able to detect how large the compressed and encrypted replies are. If you are on the same network it seems to be there are far more MITM and whatnot attacks
