PostgreSQL 11 offers the best OVER clause support among its competitors, true procedures, and improvements in FETCH FIRST and XML.
The startup storyline being told may not be the most optimal. The mental clarity of separating your lifeline from your projects may be the most thoughtful choice.
Last time we talked about free will, superintelligent predictors, and Dr. Evil planning to destroy the earth from his moon base. Today I'd like to talk about a more down-to-earth topic: time travel. The first point I have to make is one that Carl Sagan made: we're all time travelers—at the rate of one second per…
I am starting to realize that the Unix command-line toolbox can fix absolutely any problem related to text wrangling. Let me tell you about a problem I had, and how I used some Unix command-line utilities to solve it.
After a while, I decided a write a short blog post about Linux binary reversing CTFs in general. How to approach a binary and solving for beginners. I personally am not a fan of Linux reverse engin…
Many people are surprised to learn that `sed`, a seemingly simple text filtering program, is actually Turing complete. This realization prompts the question: how can a text processing utility achieve such computational power? The answer lies in sed's fundamental operations. Essentially, sed functions as a miniature...
A perfect hash function is one that is collision-free. By implication, the hash must be at least as many bytes as the key and the function is theoretically reversible, though not always tractably so. In other words, perfect hashing is a special case of encryption. Because the hash is no smaller than the key, the…
Over the course of six weeks in January and February 2019, I took an introduction to stained glass course from Olivia Vavroch at Vavroch Glass Studio in north Portland, OR.

In his 2008 white paper that first proposed bitcoin, the anonymous Satoshi Nakamoto concluded with: “We have proposed a system for electronic transactions without relying on trust.” He was referring to blockchain, the system behind bitcoin cryptocurrency. The circumvention of trust is a great promise, but it’s just…
When writing a book or course, you deal with hundreds of thousands of words and Vim helps you manage that in a sane way.
This marks the beginning of a week long adventure in Geneva Switzerland at CERN, to work on a hack project.
A few days back I read an article about how Bitcoin’s price can be sufficiently explained by Metcalfe’s law. As you read through the post, resist the temptation to click the links to learn more about Bitcoin, Metcalfe’s law etc. (Maybe you should read about Bitcoin if you have not heard of it). I have provided all the…
Hash tables are the most popular probabilistic data structure, by quite a margin. You compute some hash code then compute an array index from that hash code. If you’re using open addressing-c…
