obtu··on Valve Source Engine Running Faster on Linux than Windows
AMD64 would bring more cache pressure on the CPU, but also a lot more memory for caching the world, plus more registers, a better instruction set… For a game, I expect memory would make a large difference.
obtu··on Valve Source Engine Running Faster on Linux than Windows
It was on the front page, I saw it when it was at 40 points or so.
obtu··on Faster Zombies
You give examples of blobs, not DRM. Unless you are referring to the direct rendering manager, I have not encountered any DRM in years of using Linux on the desktop.
obtu··on Matasano Security acquired for £8.4m ($13m) - Congrats tptacek
Two years at least:

> Consideration of £8.4m - initially £4.2m, then two further payments up to £4.2m in total over next 24 months against performance related targets

obtu··on How low (power) can you go?
Sensors could manage with some sort of interferometry to rebuild an image from multiple pixels across multiple sensors. The signal processing would be similar to what is used for medical scanners. We could also see a convergence with radar, combining those pixels and algorithms with an active source.
obtu··on Facebook has more than 83 million 'fake' users
The spam followers I pick up seem to target lists of “followers of X”, where X is marginally topical to their spam.
obtu··on A Bad Privacy Bug
MySQL's warnings are silent, in the sense that the web application will never act on them. Guessing instead of failing early is a poor choice for a relational database, and is only explained by MySQL favouring ease of use and porting over data integrity.
obtu··on Faster Zombies
It still implies the Direct3D implementation stayed at 270fps. I wonder how Windows+OpenGL fared before the optimisations; presumably it was lower than 270 or OpenGL would have been the baseline.
obtu··on Bill would force patent trolls to pay defendants' legal bills
The way US politicians are funded, they do not give a shit about this hypothetical lone inventor. This is just a romantic ideal used by the pro-patent lobby to glamorise patents.
obtu··on Sorting improvements in PostgreSQL 9.2: the case for micro-optimisation
This submission's title (taken from the blog post) is more interesting.
obtu··on Sorting of integers and floats 23% faster in PostgreSQL 9.2 (long explanation)
PostgreSQL is extensible enough that runtime specialisation would be best, I think. A JIT compiler, or a compiled type-safe multi-stage[1] programming language like MetaOCaml, would give the best performance.

obtu··on Bill would force patent trolls to pay defendants' legal bills
Shouldn't this loophole be closed? Something like: only allow the exclusive owner of a patent to sue potential infringers. That isn't enough to make shell companies a losing proposition, though, because they still contain the risk of losing a suit. I prefer the bond idea, it is a simple and more direct route to making NPEs liable for their actions.
obtu··on Creating a friend recommendation algorithm from social network data
You still need the graph to run the recommender. This algorithm would help new users get up to speed quickly, with better results when the social graph is large; it's just another network effect.
obtu··on The new Digg
The data was bundled with the domain sale, thankfully. It's a shitty move that they took it offline for an unspecified duration, and that they don't plan to handle existing urls.
obtu··on The new Digg
Use the HTML validator Firefox extension. It will give you quasi-sensorial awareness of how the pages you visit are doing.
obtu··on Peter Thiel’s startup class notes in PDF
Then his stated goals shouldn't prevent people making conversions to other formats. You just have to be careful with not misrepresenting the work, something that is already part of the non-transferable author rights in a few countries.
obtu··on Ubisoft "Uplay" DRM exposed as rootkit
You asked a very laden question. You have no doubt encountered discussions about full-disclosure to know the arguments against it; giving a one-sided rehash of that topic is a provocative way to invoke an old and tired discussion.
obtu··on Ubisoft "Uplay" DRM exposed as rootkit
Google and Mozilla will certainly add it to their plugin blacklists. Trojan capabilities remote-controlled through a browser, that's a very serious security risk to their users.
obtu··on Do you check HTTPS certificates in your API clients?
Yeah, but that's proxy, not reverse proxy. It's possible to do something fiddler-like using apache or nginx to mitm oneself and dump everything that goes through.
obtu··on Do you check HTTPS certificates in your API clients?
It's easy enough to generate a snakeoil cert and use its public part as your cert bundle. On Debian/Ubuntu, just install the ssl-cert package, and point to /etc/ssl/certs/ssl-cert-snakeoil.pem as your certificate bundle; the private key is at /etc/ssl/private/ssl-cert-snakeoil.key .

Or just serve your app/API/etc from different urls, plain HTTP for development and HTTPS for preprod and production.

obtu··on Do you check HTTPS certificates in your API clients?
In Python, a sufficiently recent httplib2 will require valid certificates by default; same with the requests library. Both let you use your own cert bundle, as a quick-and-dirty way to do certificate pinning. That's reason enough to discourage the use of Python's standard library for http requests (another reason is that it's quite low-level).
obtu··on Gnome: Staring into the abyss
I love it, because it feels streamlined and gets out of the way. I don't really care to participate in flames (the sort that Benjamin linked from his blog post), so I'll just voice some support here.
obtu··on The IPS LCD Revolution
I'm used to multiple desktops (gnome 3, gnome before that), and multiple panels turn out to be useless to me. I just can't spread my attention across two monitors, whereas I switch desktops without thinking about it.
obtu··on Go is boring
Indeed, “the architecture of GHC” mentions some uses of GHC as a library: http://www.aosabook.org/en/ghc.html
obtu··on Go is boring
What do you think of leksah?
obtu··on The Humble Music Bundle
Humble indie movies bundle! With stuff like the PhD movie, something by Ian Hubert, and maybe a youtube series to top things up.
obtu··on The Humble Music Bundle
Two other music bundles were mentioned by their creators on the reddit thread:

obtu··on The Humble Music Bundle
Indeed, I complained about it as well. It's annoying because I can't download the tracks in order and play them immediately after buying. Plus it's a noob error that most decent trackers will warn you against, and it was in fact faster for me to grab the albums I wanted from one such tracker.

obtu··on OAuth 2.0 and the Road to Hell
This stuff is used within silos (Watson, bio/medicine research), but expanding it to the web is hard because entities that collect data want to monetise it, and do not see the value in reducing friction.
obtu··on Kevin Rose reflects on Digg, the dangers of outside investors, and his legacy
“don't take too much financing” is a recognition that Digg v4's failure (and you should look at Alexa graphs to see how significant that was) was due to ignoring the community to give investors the site they thought they wanted.
