I wanted to think about what the things that I value. The first thought that came into my mind was “learning”. I really like learning new things, whether it would be facts or techniques, or how to use a certain tool. But why do I value learning these things. Well, because it feels to be empowered to do things like edit code faster by knowing and practicing emacs shortcuts or eat healthier by knowing a.little bit aboht how different componen....

Siri can get confused, of course, as every iPhone owner knows. For example, searching for the Pokmon ‘Charmander’ kept autocorrecting to Mander. But this can be excused. It’s a freaking Pokdex. In your pocket. Just think about how your 10-year-old self would feel about that.” Back in my day... Permalink.

Turing proved with his halting theorem (There's a nice simple proof here ) that there is not a correct program $$Halt(p, i)$$ that returns true if program p halts on input i, and returns false if the program does not halt (i.e. if it loops forever). (This is for Turing-complete languages, i.e. languages with programs that may loop forever). However, what does exist, is a correct program HaltM (short for Halt Maybe), that returns one o....

Introduction If you are using 3rd party packages, (packages that you don't own or control), you will want a way to create a reproducible build every time you build your projects. If you use 3rd party packages directly and the package authors change things, your projects could break. Even if things don't break, code changes could create inconsistent behavior and bugs. Keith Rarick's tool godep is a great step in the right direction f....

My grandfather lived to be 100 years old. If the Blanc blood running through my veins holds up like my grandfather’s did, then I’ve still got 68 years to go. Do I really want to spend one ounce of energy trying to make random people on the internet like me? Will that matter at all in six decades from now? I’d rather spend that energy strengthening my own core values, dating my wife, building life-long relationships with my sons, serving my ..

Overcast will use speed-accurate labels. I’ll take the heat in reviews.” Excellent. Instacast’s inaccurate, “legacy-style” labels have always annoyed me, especially when trying to decide whether I had enough time to play the latest episode of Roderick on the Line. Permalink.

SGA bigger than the amount of HugePages configured (Linux – 11.2.0.3)

I just learned something new yesterday when demoing large page use on Linux during my AOT seminar. I had 512 x 2MB hugepages configured in Linux ( 1024 MB ). So I set the USE_LARGE_PAGES = TRUE (it actually is the default anyway in 11.2.0.2+). This allows the use of large pages (it doesn’t force, the ONLY option would force the use of hugepages, otherwise the instance wouldn’t start up). Anyway, the previous behavior with hugepages wa..

The step-based time-travelling sequel to Iteration: make every move count as you send short-lived clones into the past. Think in 2+1D (2 spatial + 1 time dimension) as you incrementally re-write the past. Iteration II takes a very different approach to Iteration. By being step-based (rather than time ticking automatically as in Iteration) it allows for more precise and complex puzzles. To aid you, a timeline is shown at the bottom of th..

I would have loved to have this back when I played Pokmon LeafGreen and Pokmon Saphire. Instead I had Prima Games’ Pokmon Pokedex Collector’s Edition which, although a great book for its time, simply cannot compare to the power Wolfram|Alpha will afford its users. I don’t even play the game any more and I’m still excited. Permalink.

I probably wouldn’t have gotten into the Bulgarian National Math team and after that into MIT if I had followed commands. It happened when I was 7th grade and my school was selecting a team to compete in a national mathlete competition. The days the team selection exam was supposed to happen, there was also a literature exam, part of the standard curriculum, which my mother told me to attend to. After a brief argument, I said I will, but p....

Oh, hi there. In case you’re interested, I’ve just made a first release of my puppet-shorewall module . This isn’t meant as an exhaustive shorewall module, but it does provide most of the usual functionality that most users need. In particular, it’s the module dependency that I use for many of my other puppet modules that provide firewalling. This is probably where you’re most likely to consume it. In general most modules jus..

I increasingly hear experienced professionals at Agile conference bemoan the blind adherence to the techniques of Scrum without understanding the principles and values that make it work. I also encounter many software professionals who are overwhelmed by the amount of things that they..

Figure 1. This figure has automatic figure numbering. I had a feature request for automatic figure numbering, like latex. I was revamping this plugin for Pelican 3.3 anyway - and this didn’t seem too hard - so I decided to add it. So, the Better Figures & Images plugin now supports automatic figure numbering. To enable this for all posts, just add this to your config file: FIGURE_NUMBERS = True If you want to enable this pe....

There are quite a few changes in Pelican 3.3 - most of them minor, but a few which might mean making some changes to your site in order to upgrade. This is what I did to move my site from Pelican 3.2 to 3.3. The change that had the biggest impact and took the most work was around image linking - caused by a combination of things. I think I was doing it wrong before and things changed in a way that meant this no longer worked. I also h....

AdRoll is going gangbuster when it comes to hiring engineers. We’re adding headcount in a very competitive market on an ongoing basis, and we continue to differentiate ourselves with the depth and complexity of our engineering problems. We take a very collaborative approach to engineering but give individuals a high degree of project ownership. While we bounce ideas off one another and learn together, each engineer is tackling large problem....

Shawn Blanc on Nick Heer’s predictions for Apple’s event next week: “From my armchair, I say Nick is probably pretty close to the money here.” I really hope so: I have been holding out for a new MacBook Pro since before Apple unveiled the new Airs; it would be a huge disappointment if I had to continue waiting until January. On the tablet front, I may also consider purchasing a new iPad along with a MacBook Pro and a new iPhone. Widely ru..
