Have you ever wondered what happens when you call Array.prototype.sort()? What did the creators of JavaScript use to sort items in the language? Today we’re going to answer that with our continuing series on common sorting algorithms. But first, the answers to last article’s Daily Problem.

Two months ago I hadn’t launched any solo project that got users. Until lately everything I had ever done was with someone else, usually with a compatible skillset. The problem with this approach is that if someone on the team loses interest or is busy the project dies out. As this happened a couple of times I decided to take some time and work on projects by myself. The products I launched Klipped.in ( https://klipped.in )

If I'm honest, I'd forgot that Real Media Variable Bitrate was even a thing. Which is probably for the best as it's best left buried in the shrouds of time Unfortunately, whilst sorting some old files, I found a bunch that were in RMVB format, so wanted to convert them to something a little more sane (and more widely supported) without sacrificing quality This snippet details how to convert a directory of RMVB format files to X264 MP4..

My imgur had been acting up for a while now.

So it wasn’t getting blocked by … Continue reading Firefox imgur failure

PHP's print_r can be very useful when testing and debugging, but LUA doesn't have a native equivalent This function implements similar functionality, though for convenience rather than force printing the generated result, it returns it as a string (so you can write it to a log if that's preferred Read more…

As we discussed in the last article, sorting is the most frequent activity a computer performs, and also happens to be the most thoroughly-studied activity by computer scientists. Over the next few articles, we’re going to explore the tried-and-true sorting algorithms have that defined the field throughout the years, introducing relevant advanced data structures along the way.

Last year we held a machine learning seminar in our London office, which was an opportunity to reproduce some classical deep learning results with a nice twist: we used OCaml as a programming language rather than Python. This allowed us to train models defined in a functional way in OCaml on a GPU using TensorFlow.

Earlier in 2016, I came up with the idea of creating a Python module which could provide functionality of profiling functions w.r.t. SQL queries and tell exactly at what lines of function, the queries were happening. I called that package Goofy and created it with the engineering of Python AST manipulation. You can read the post on it here later. It helped us profiling views serving AJAX requests but it had some limitations too. E.g. we....

yahoodevelopers : By Arjun Mannaly, Senior Software Engineer At Oath , multiple ad platforms use a high throughput, low latency distributed key-value database that runs in data centers all over the world. The database stores billions of records and handles millions of read and write requests per second at millisecond latencies. The data we have in this database must be persistent, and the working set is larger than what we can fit in....

Here's an example from a very quick sketch during tonight's commute home: Though it may look black and white, there are a dozen colors captured in this quick sketch. In this post, I briefly describe the notation. The letters are based on my oil painting palett....

As recently as twenty years ago, if people wanted to publish a book, they would either have to convince a traditional publisher to publish their book, or shell out hundreds or thousands of dollars in order for a self-publisher to print their book for them. Some of these old self-publishing companies still exist - such as Morris Publishing, who, according to their website , charge around $5 a book for a 40-page book with a 25-book minimum. ..

Imagine that you installed a random Python package from PyPI. There’s a good 13.5% chance that the package has no licensing information. Considering it’s not uncommon to have hundreds of dependencies and sub-dependencies in a typical Python application, there’s a very good chance of using unlicensed code. Depending on the context, the consequences of using unlicensed software could be anywhere from insignificant to disastrous. Ok, that’s a ..

So I've been trying to do as much of my local development from within docker containers. Each project I tweak things to be a little bit nicer than the last one. Most recently I went to update my tealeaves ssh key parser utility (which is coded in rust). Initially I was getting all manner of frustrating errors trying to get a reproducible version of rust installed with 1.30, clippy, and rustfmt. I bailed one night in frustration only to late....

In the original PHP prototype of SnailLife there exists a very rudimentary genetics system. Snails had what I called “visual traits” and “functional traits”. Visual traits had genes associated with them. The genes were all stored in the snail’s table and each gene had two “alleles”. During breeding I’d make virtual Punnett Squares of sorts to pass on genes from parents to offspring. But the system was inflexible - each allele for each gene ..
