In my last article, The iPad Pro , I promised to write about Apple’s perpetuation of its second-generation tablet. I actually set out to discuss both the iPad 2 and a hypothetical Pro model in that piece, but long-windedness got the better of me and I had to push it off until now. Given that these points have already been made in parts elsewhere, I will keep this brief. Permalink.

For any given finite string, there is a compression method (an invertible (one-to-one) function) for which the finite string is compressed to the empty string. Proof: Given a finite string i, we can construct the one-to-one function \( C_i \): $$ C_i(x) = \begin{cases} \epsilon &\mbox{if } x = i \\ i &\mbox{if } x = \epsilon \\ x &\mbox{otherwise} \end{cases} $$ which means that $$C_i(i) = \epsilon$$ i.e. the input string \( i \)..

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.

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....

It’s been a long time coming, the main delay in getting iOS 7 support into your hands has been with the need to upgrade all the servers. Apple seems to require OS upgrades as well when it updates xcode so we had to go one by one and update everything. This is now all in place and you can start building apps that take advantage of iOS 7 functionality and are built using xcode 5.

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 ..

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..

I find programming very similar to mathematics as far as the thought process is concerned. Programming involves solving problems by thinking abstractly about quantity, relationship and behaviour. As a programmer I have to either come up with a new algorithm or customise an existing one for the current problem and optimise it. The formal methods of thinking that mathematics demands — careful reasoning, searching for counter-examples, spotti..

I got into programming because I wanted a platform to express my ideas creatively and give them life. Just like every programmer, I wanted to work on cutting edge technologies and crack difficult problems. I strove to find the best solutions for the problems I came across and I did. When someone asked what I did for a living, I proudly said "I build cool products using latest cutting edge technologies." I felt invincible but neither satisfi..

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....

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.
