Porting Alpine Linux to RISC-V

I recently received my HiFive Unleashed, after several excruciating months of waiting, and it’s incredibly cool. For those unaware, the HiFive Unleashed is the first consumer-facing Linux-capable RISC-V hardware. For anyone who’s still lost, RISC-V is an open, royalty-free instruction set architecture, and the HiFive is an open CPU implementing it. And here it is on my dining room table:

This board is cool. I’m working on making this hardware available to builds.sr.ht users in the next few months, where I intend to use it to automate the remainder of the Alpine Linux port and make it available to any other operating systems (including non-Linux) and userspace software which are interested in...

How to abandon a FLOSS project

It’s no secret that maintaining free and open source software is often a burdensome and thankless job. I empathise with maintainers who lost interest in a project, became demotivated by the endless demands of users, or are no longer blessed with enough free time. Whatever the reason, FLOSS work is volunteer work, and you’re free to stop volunteering at any time.

In my opinion, there are two good ways to abandon a project: the fork it option and the hand-off option. The former is faster and easier, and you can pick this if you want to wash your hands of the project ASAP, but has a larger effect...

sr.ht, the hacker's forge, now open for public alpha

I’m happy to announce today that I’m opening sr.ht (pronounced “sir hat”, or any other way you want) to the general public for the remainder of the alpha period. Though it’s missing some of the features which will be available when it’s completed, sr.ht today represents a very capable software forge which is already serving the needs of many projects in the free & open source software community. If you’re familiar with the project and ready to register your account, you can head straight to the sign up page.

For those who are new, let me explain what makes sr.ht special. It provides many of the trimmings you’re used...

This year’s ToxCon was super fun, thanks to everyone who attended it!

Однажды китайский ученый Ли Хунь Янь обнаружил некоторую незначительную, однако, существенно отличающуюся от фона корреляцию между количеством псилоцибина потребляемого корфуцианскими медузами и характером передвижения оных по стенкам четырехсотлитровго шарообразного аквариума, установленного в лаборатории по случаю празднования сто второго полугодичного затмения от начала новой эры Сингулярного Прорыва. Недолго думая, Ли Хунь Янь приделал к щупальцам медуз источники излучения в видимом диапазоне но с разной длинной волны, заснял весь процесс шестью камерами с 48 часовой выдержкой, симметрично расставив последние вокруг сосуда, где резвились подопытные и через неделю собрал прелюбопытнейший материал, который, в свою очередь, лег в основу фундаментального труда, ныне известного, как теория полутретичных n-многообразий простой метрики Ли Хунь Янь, с которой (с некоторыми упрощениями и оговорками) я, по мере сил, постараюсь познакомить любопытного и пытливого читателя.
