Advanced Image Dithering with Dither Boy by Studio AAA

Dither Boy is a software that produces very cool dithering effects on images. You can pick from multiple algorithms and customize them. Pretty cool! I wish I would have the same kind of things but for vector content. That is definitely something I keep in mind for my plotter art.

LLM writes low-level code and improves performance by 2x

An incredible mise en abyme happened yesterday. A developer managed to get 2x improvement by letting DeepSeek-r1 write code for a specific part of llama.cpp. 

Surprisingly, 99% of the code in this PR is written by DeekSeek-R1. The only thing I do is to develop tests and write prompts (with some trials and errors)

According to the prompts shared by the developer, the model spent thinking 3 to 5 minutes per response.

DHH's absurd rant on ADHD

I got pissed off a bit too easily reading one more absurd take on ADHD. This time, it comes from DHH who blessed us with his weakly-informed opinion. Apparently, we ADHDers aren't crippled enough in our daily life that we  have to suffer arrogant apes throwing feces blog posts at us. ADHD is a serious condition and society at large must face it instead of dismissing it.

ADHD is a subject of research since at least 1775

In 1775, Melchior Adam Weikard, a prominent German physician, published the textbook Der Philosophische Arzt. Weikard's text contained a description of ADHD-like behaviours, possibly the first ever such description in medical literature (source)

ADHD is associated with an increased mortality rate.

ADHD was associated with significantly increased mortality rates. People diagnosed with ADHD in adulthood had a higher MRR than did those diagnosed in childhood and adolescence. Comorbid oppositional defiant disorder, conduct disorder, and substance use disorder increased the MRR even further. However, when adjusted for these comorbidities, ADHD remained associated with excess mortality, with higher MRRs in girls and women with ADHD than in boys and men with ADHD. The excess mortality in ADHD was mainly driven by deaths from unnatural causes, especially accidents. (source)

ADHD is associated with alcohol and substance abuse disorders

Substance use disorders are a frequent comorbidity in adult ADHD. This review discusses the relationship between adult ADHD and substance use disorder, including use of licit and illicit substances such as nicotine, alcohol, cocaine and cannabis. (source)

ADHD is way more prevalent is prisons than in the general population. 

Compared with published general population prevalence, there is a fivefold increase in prevalence of ADHD in youth prison populations (30.1%) and a 10-fold increase in adult prison populations (26.2%) (source)

It took me 5 minutes to search for this information. Granted, it's not easy as opening X and reducing this disorder to popping pills for morning's productivity routine. To be honest, if there was a pill to avoid reading dumb shit on the internet, I would take twice the recommended dose everyday.
