What is SAP?

What's SAP? And why is it worth $163B? Every year companies spend $41B on enterprise resource planning software, commonly known as ERP. Today, almost every large business has some sort of ERP system implemented. But most smaller businesses generally don’t purchase any ERP system off the shelf, and most

KnightOS was an interesting operating system

KnightOS is an operating system I started writing about 10 years ago, for Texas Instruments line of z80 calculators — the TI-73, TI-83+, TI-84+, and similar calculators are supported. It still gets the rare improvements, but these days myself and most of the major contributors are just left with starry eyed empty promises to themselves that one day they’ll do one of those big refactorings we’ve been planning… for 4 or 5 years now.

PHP Sucks! But I Like It!

I read a rather interesting post yesterday called PHP: a fractal of bad design. It’s been getting a lot of traffic among the PHP community lately because it’s rather inflammatory. But to be honest, it

Pressure Based Anti-Spam for Discord Bots

Back when Discord was a wee little chat platform with no rate limiting whatsoever, it's API had already been reverse-engineered by a bunch of bot developers who then went around spamming random servers with so many messages it would crash the client. My friends and I were determined to keep our discord server public, so I went about creating the first anti-spam bot for Discord. I am no longer maintaining this bot beyond simple bugfixes because I have better things to do with my time, and I'm tired of people trying to use it because “it's the best anti-spam bot” even after I deprecated it.

Using "Bona-Fida" reversed engineered Headers to distribute vst2 "like" plugins

Dear fellow devs, i just started out developing audio plugins and planning on starting a business with that. Since a few days i am sleeping bad because i found out that distributing VST2 PlugIns will be illegal for me as i didn’t sign a license agreement with Steinberg before October 2018. This would be a major drawback for any new business trying to sell audio plugins, since one of the most used DAW (and my beloved favourite) didn’t support VST2 until recently in their current major version. ...

Announcing website snapshot for Trandoshan

When I have written my article for Trandoshan [/building-fast-modern-web-crawler/] I didn't expect so much positive feedback. More than 15k views on the article, hundred stars on the Github repository... I am very happy about it. My first plan was to stop the development right after 1.0.0 was working and the article was published in order to move on new project(s). But despite of that I have had several cool features in mind. Since the project seems to interest some people I have decided to im

Hello darkness, my old friend  |

Many devices now support an operating system wide dark mode or dark theme experience. This post explains how dark mode can be supported on web pages, lists best practices, and introduces a custom element named dark-mode-toggle that allows web developers to offer users a way to override their operating system level preference on specific web pages.
