A taste of the secret sauce behind JustTalkTo
At JustTalkTo, we realized early on that the idea is not deep tech. There isn’t really a good justification for machine learning, deep learning, a kernel driver, or low-level optimizations. What we do have is a kick-ass product and the tech to back it up. One of the more interesting pieces of tech that we…
A Few Geekcon Tips – Experiences from a Maker Hackathon
A couple of months ago I went to Geekcon. For those not familiar – Geekcon is a “conference/hackathon” for makers – you come, build a ridiculous project, eat some food, barely sleep at all, play a bit with other people’s projects, and then go home. The idea about the project being ridiculous – it has…

Working with Intervals
Over the last couple of months my team at Flytrex had occasion to use intervals more than once, and in both cases the team asked me, “What’s the right way to solve this?”. Since this is a common problem, I thought I’d write a short post about it. Most interval problems seem deceptively simple, while…

Rhyme and Reason with Python
After reading xkcd’s blog, I went to LimerickDB.com. It looks and works just like bash.org, but for limericks. Quite amused with some of the limericks available, I wanted to try and compose my own. The first one came out fine, but I got stuck without a rhyme for the second one: a man named guido…
Manually fuzzing my own compiler
As I mentioned before, I had to write a compiler for simplified CPL. An obvious requirement was that the compiler generate correct code. A less obvious requirement, but important none-the-less, was that after a syntax error, the compiler will keep parsing the source program. Now, the default behavior of a parser generated by Bison for…
Fractals in 10 minutes no. 3 – The Dragon
When first I looked through the pages of the book “Hacker’s Delight”, I found myself looking at the chapter about bases. There I learned a very curious fact – with the digits of 0,1 and the base of -2, you can represent any integer. Right afterwards I learned something even more interesting – with the…
Fractals in 10 minutes No. 2 – Recursive Spring
Imagine a straight wire. Bend this wire until its ends meet. You get a ring. Next stage. Take another straight wire, bend it as before, but this time, don’t let the ends meet, instead continue bending the wire more and more, until you get a spring. Now, Think of this spring as the first wire,…
Python module usage statistics – Cont.
Well, very embarrassingly for me, turns out I had a bug in my original post and code. As per Doug’s suggestion, I tried running the script I wrote on the standard library, and got results I didn’t quite believe. So I checked them, opened socket.py, and there was an “import _socket”. However module “_socket” was…
Python module usage statistics
IMPORTANT UPDATE: The code I used to create these statistics had some bugs. The fixed statistics are available here. After reading Doug Hellman’s post about python stdlib modules he needs the documentation to, I commented there that I need the documentation for logging because I don’t use it too frequently. Later, I thought a little…
