Scaling past Port Exhaustion: when 100k+ ports were not enough

One of my favorite technical projects involved overcoming a network constraint. The virtual machines (VMs) hosting the core services kept exhausting available ports. Once all ports were used up, new connections would fail, tanking our availability and reliability. Read on to learn how we overcame this issue and opened up opportunities to reduce costs by a third.

While it has been a very challenging and difficult time for the company, it cannot even remotely be compared with the horrendous situation that the people of Ukraine are facing on a daily basis, caused by the war. Once again, we condemn this aggression, and have and will continue to stand by the people of Ukraine, including our colleagues and their families. More here . I’m using JetBrains products when I’m not in (neo)vim. For C#, R..

The Data Bus is a pattern that can help you tidy up data flows, and helps to keep track of the preprocessing steps taken. It is a simple, language-agnostic pattern that can be used to make sense when multiple transform steps are involved.

Back Story For my entire time as a web developer, front end web layout has been a kludgey messy nightmare. I think about every few years since 1999 or so I spend a few days reading the latest CSS features that are the new hotness and advertised as finally going to solve pervasive problems with layout, centering, alignment, etc. I've just been through so many rounds of this nonsense: rounded corners, sticky headers and footers, gradients, w....

Accelerating zk-SNARKs - MSM and NTT algorithms on FPGAs with Hardcaml

In 2022 a consortium of companies ran an international competition, called the ZPrize , to advance the state of the art in “zero-knowledge” cryptography. We decided to have a go in our free time at submitting solutions to both the Multi-Scalar Multiplication (MSM) and Number Theoretic Transform (NTT) tracks, using the same open source Hardcaml libraries that Jane Street uses for our own FPGA development. We believe by using Hardcaml we w..

As you build a computer system, little things start to show up: maybe that database query is awkward for the feature you are building, or you find your server getting bogged down transferring gigabytes of data in hexadecimal ASCII, or your app translates itself to Japanese on the fly for hundreds of thousands of separate users. These are places where your abstractions are misaligned - your app would be quantitatively better if it had a bet..

Oscar the Grouch, a character from the popular children’s television show “Sesame Street,” can be seen as a modern-day embodiment of the Hellenistic philosophical tradition of Diogenes the Cynic. Like Diogenes, Oscar rejects the trappings of mainstream society and embraces a simpler, more ascetic lifestyle. In Oscar’s case, this means living in a trash can and rejecting the consumerist values of capitalism. In the words of Guy Debord, the....

There’s no real “recommendation algorithm” here. Mastodon 4.x has a “trending” feature, but that’s it. Users that your instance members follow have their content pushed to your instance, and their repeated posts reach your instance too. When content reaches your instance, you can reblog it to help it reach your followers’ instances. Federation is a privilege. If “Instance A” members repeat or reply to “Instance B” members, they increase....

With the incredible capabilities of ChatGPT released last week, it got me wondering what AI would struggle with, at least in the foreseeable future. Ethics? Very likely. Authentic emotion? Probably. How about humour? Let’s find out… Being a Brit, I should probably choose Monty Python or the like, but if there’s one comedian whose joke … Continue reading “Brand New” Mitch Hedberg Jokes (Thanks to AI) →

Despite its name suggesting otherwise, Dune II was a first – a real-time strategy game that sprang out of the box with almost every gameplay attribute and control system seen in every RTS since. In direct lineage, it was the father of the globally successful Command & Conquer franchise, in that its code was used as a basis of the first game of the series. Yet in terms of wider influence, the battles first fought out on the vibrant sands of ..

Kernel density estimation boundary correction: reflection (ggplot2 v3.4.0)

eng
Kernel density estimation (KDE) is a popular way to approximate a distribution based on the given data. However, it has several flaws. One of the most significant flaws is that it extends the support of the distribution. It is pretty unfortunate: even if we know the actual range of supported values, KDE provides non-zero density values for the regions where no values exist. It is obviously an inaccurate estimation. The procedure of adjustin..

I’m well aware that I may have a bit of an obsession with fonts . I don’t think that’s too unusual for someone who works in tech, however. Sites like Programming Fonts exist to let people test drive and compare a bunch of different fonts. Just for fun, I thought I’d write up some of the features I look for in a programming font that I’ve come to deliberately pick out. Critical letter forms: i, I, l, 1; o, O, 0 # These are probably....
