Pixels with 8 bits per channel are normally sRGB encoded because that allocates more bits to darker colors where human vision is the most sensitive. (Actually, it’s really more of a historical accident, but sRGB nevertheless remains useful for this reason). The relationship between sRGB and linear RGB is that you get an sRGB pixel by raising each component of a linear pixel to the power of . It is common for graphics software to perform....
I spent a weekend with the latest Google Chromebook and wanted to update real quick with my impressions.
In almost all of the Exadata migration projects I’ve been part of, the client sees immediate speedup & performance increase when testing their workload on Exadata (of course, we’ve made sure that we do plan & execute the tasks right). However, my performance geek’s nature usually doesn’t allow to stop there and leave the client with just 2x or 3x performance increase. For data warehousing and reporting workloads, Exadata can do much better ..

I’ve posted the final slides from my talk this year at DEFCON and Black Hat, on breaking out of the KVM Kernel Virtual Machine on Linux. Virtunoid: Breaking out of KVM from Nelson Elhage [Edited 2011-08-11] The code is now available. It should be fairly well-commented, and include links to everything you’ll need to get the exploit up and running in a local test environment, if you’re so inclined. In addition, as I mentioned, this bug was fo..

Oracle released Java 7 on July 28, 2011. This is nearly 5 years after the release of Java 6 in December 2006. The release received a lot of bad press, both because it is very meager on features, and because it shipped with a severe bug. Nevertheless, once the most serious bugs have been fixed, you might think about starting to use Java 7. What will this mean? New language features Java 7 has a few new language features.
On July the 27th I went down to Christchurch for the South Island Chess Championship and and the South Island Rapid Championship at the Canterbury Chess Club. The events were 2 games a day for 4 days (Wednesday to Saturday) for the Champs and then 6 games on the Sunday for the rapid. I flew … Continue reading 2011 South Island Champs
So far on this blog we’ve assumed familiarity with the programming languages used (at the time of this writing, this is Mathematica and Java). This is unfair for the mathematicians who have little to no programming experience, and we admit that some readers tend to skim those technical sections with source code. As our work on this blog progresses, we recognize that the mathematical elegance is sometimes inherently manifested within the cod..

To me, some of the most fascinating problems are the ones that are only visible in hindsight. The angled measuring cup might be the best example of this. With a standard measuring cup, you have to bend over or lift the cup to see how much of a substance you've measured. On the other hand, the angled measuring cup can be read while standing upright. Yet when asked, most people didn't realize the problem with a normal measuring cup until afte..
I got a Wacom Intuos4 yesterday. Upon getting home that night, I excitedly unpacked it, installed the drivers, plugged it in, and tried to draw.
Xamarin, la compagnia che ha preso in mano il Progetto Mono dopo l’addio di Novell, ha appena rilasciato Mono 2.10.3. Ne da annuncio lo stesso Manuel de Icaza, storico deux-ex-machina del progetto e fondatore di Xamarin. Si tratta per lo più di una versione di manutenzione che risolve numerosi problemi, primo fra tutti l’instabilità di Mono sull’ultima versione di MacOS X Lion.

Hard Numbers - boyter.org - 15 years ago - eng
Thought I would quickly post some hard numbers showing the number of searches since searchco.de launched. The results surprised me somewhat actually. 2011-7 13636 2011-6 8154 2011-5 6183 2011-4 8532 2011-3 10886 2011-2 6476 2011-1 948 I could dig into the results more closely since a lot of those could be the ajax firing off events like “a” and the like but I do like the upwardish trend.

Just a quick post, I’ve made some changes to the live tile images. Hopefully it now looks a bit better, let me know what you think. Thanks in advance for any feedback.
It's been quite a while since I updated this blog, very lax of me, sorry! The lack of updates appears more indicative of how busy I appear to have been since presenting the error handling draft work at NANOG (which looks to be the last post!). Since January, I've presented at the IETF in Prague, and then again in Qu�bec City - particularly on a number of aspects of the work that I've been documenting here for some time!

Per qualche giorno non si pensa al codice e si sta alla larga, per quanto possibile, dal computer. Buone vacanze a chi ci va, e buon lavoro a chi non va. Per i più curiosi. La foto è stata scattata la settimana scorsa durante la salita della classica via Maria al Sass Pordoi (2950mt, Gruppo del Sella, Dolomiti orientali). Se proprio volete annoiarvi date una occhiata alle altre.

I just saw a post in my tweet stream by Derek Neighbors in which he asserts that todays Rubyists are a “drone army”: The leaders have disappeared.  The second and third wave are just implementors. They are not idealistic.  The Merb team emerged full of new ideas and a swagger of yesterday but all that died when they merged back into Rails. It used to be about changing the world.  Now it’s just about tools.  Workflows are broken an....
