To be fair, comparing core counts directly, each of those ARM processors is quadcore - so there are actually 192 physical cores in that 3U rack, not 48. That said, I'm not convinced ARM is ready for server applications either. This mig

If you set an application to use more file descriptors than ulimit -n returns, then either the application will be smart and fix its configuration by using MAX(configured limit, ulimit -n) or it'll start dropping requests because it&#x

I use an ad blocker. I used to use it without a filter list and would manually block any ad I found intrusive (e.g. Flash ads, ads that pick words out of the page content and highlight them, animated image ads), but then it simply became to

I've found that the best ways for validating email addresses, in order, are: checking for the '@' sign, resolving the hostname to the right of the '@' sign to see if it has MX records (or an A record, since the spec

The criminal complaint[1] mentioned the FBI searching for the earliest mention of Silk Road. The earliest they found was a user called 'altoid' advertising it in two separate places (including bitcointalk) around the same time. La

I remember looking at that, but Twisted's epoll reactor was a C extension at the time. It looks like Twisted 12.1.0 switched to using the epoll provided by the Python base library, but that was released about a year after I was origina

Yep, this was on a Debian 6.0.2 install, with packages from apt.

This was with Twisted 10.1.0 and Python 2.6.6. I remember being in extreme disbelief when I found that it was using select/poll instead of epoll (who does that, especially when they already have epoll support?). I ended up writing this

I actually experimented a while ago by running a long-running Twisted-based daemon on top of PyPy to see if I could squeeze more speed out. PyPy did indeed vastly increase the speed versus the plain Python version, but once I discovered tha

I don't think it's entirely a corporate move here. Free software contributions aren't infinite; if you have $N developers working on integrating support for display servers, then it's simple math that having to support t

This isn't entirely correct; rdiff-backup will give you a full copy of the latest version of the file as well as a set of binary diffs that can be applied in sequence to roll it back to an earlier version. rdiff-backup will actually en

If you use the printable representation of the hash, the dictionary of characters that the hash uses is only digits 0-9 and a-f. While they likely still won't guess this, it's better to use 40 characters of the printable output of

No, the article says that only a few lawsuits have resulted in damages per section 512(f) of the DMCA [1] (which places a penalty on knowingly misrepresenting a work when filing a DMCA notice against it, if I am reading correctly). It sound

I live in the bay (but not SF), and the biggest thing that would would give me pause here is that I don't want to live in Boise, Denver, or Phoenix. Some people are fine with living anywhere. Others are looking for good weather, a spec

FreeNode's use is a bit more extensive than just requiring an email address - you have to create the account from a non-Tor IP, so if you do something bad and get banned, they ban the account (thus preventing further access from you vi

It surprises me that the SYN attacks are being mitigated on the machines themselves; I was under the impression that this is typically done with hardware firewalls that offload the TCP handshake (thus filtering out spoofed SYN packets and o

Typically, noreply addresses are used as a blackhole for mail that probably won't be replied to, and any replies are either auto-generated (e.g. mail delivery failure notices), spam, or other undesirable mail. I have seen a good compro

There's another interesting method for speeding up regex searches as well - a trigram index[1]. This is what Google's code search used to do. A simple command-line version written in Go[2] was released for local use. There's

I don't think this analogy works. With this analogy, they'd have to be adding bugs to the code and then "finding" them to get the reward. In this case, having a reward would most likely result in more people specifically looking for bugs, b

It's rather disappointing that this doesn't default to using nmap's -PN option, since they can be reasonably sure that the host actually is up (after all, it just requested the web page). Not all routers respond to ping.

The attackers would just find such a user and spoof their IP. DDoS is a hard problem to solve, and it's a shame that so many ISPs and datacenters don't work harder to prevent spoofed traffic. On top of this, they'd still need routers and sw
