jobstijl··on Evaluation of Bfloat16, Posit, and Takum Arithmetics in Sparse Linear Solvers
Our experiments demonstrate that tapered-precision arithmetic consistently outperforms IEEE 754 floating-point numbers in all tested scenarios. Among the tapered-precision formats, takums exhibited exceptional performance, outperforming bfloat16 in every case. While occasionally marginally less accurate than posits, takums delivered comparable results overall and demonstrated superior numerical stability. Notably, we successfully introduced the application of 8-bit posits and takums in mixed-precision iterative refinement, marking a possibly significant milestone in numerical computing. Additionally, GMRES exhibited particular benefit from tapered-precision formats, with takums delivering outstanding results, surpassing posits in all cases.

Impressive results from Takums (https://arxiv.org/abs/2404.18603).

They also seem better then Posits for implementation in hardware. https://arxiv.org/pdf/2408.10594

jobstijl··on Testing GPT 4's code-writing capabilities with some real world problems
Wouldn't a better formulation be: "Give me the shortest route with a cost of 5 or lower with the minimum fire tiles in the path necessary" Since your formulation doesn't care about the amount of fire tiles in case there is no other solution?
jobstijl··on Where are my Git UI features from the future?
I'm still hoping https://pijul.org/ usage will grow.

Any specific reasons why you think its fraud?
jobstijl··on Revamped German stellarator should run longer, hotter and compete with tokamaks
In france they are building a next privately founded stellerator which seems intresting. https://stellarator.energy/
jobstijl··on On my resignation as regulator of the Dutch intelligence and security services
This is not the will of the people in the Netherlands. We had a referendum a few years ago about the laws for spying (sleepwet). Their was a clear vote for not allowing bulk spying. The rules that currently are broken down where made in reaction to that referendum.
jobstijl··on Ask HN: Has YouTube peaked?
I hate the youtube search these days. You get back a very limited list off content you serached for and a lot off videos that are "related" to your search.

Not in a parliamentary system like they have in the Netherlands.

This happens quit a lot with github lately it seems.
jobstijl··on Dutch crime reporter dies after being shot
We haven't legalized the production of drugs in the Netherlands, so our 'gedoogbeleid' does not help against organized crime. It does help on the health side of the debate though.
jobstijl··on Things about the new Firefox browser for Android
For me it did a few updates ago, now it's pretty much stable. I really do like this release and i can live with not all extentions being enabled on the nightly, but for releasing this to stable users i would think they should first fix the extentions.

Why wouldn't they make it [[strict]] by default?
jobstijl··on Why Are Economists Giving Piketty the Cold Shoulder?
His work doesn't depend an a normative judgement that inequality is a bad thing. His work is an observation about how inequality works, not a judgement.

jobstijl··on Faust by Johann Wolfgang von Goethe
Faust

I've studied now Philosophy

And Jurisprudence, Medicine,—

And even, alas! Theology,—

From end to end, with labor keen;

And here, poor fool! with all my lore

I stand, no wiser than before:

I'm Magister—yea, Doctor—hight,

And straight or cross-wise, wrong or right,

These ten years long, with many woes,

I've led my scholars by the nose,—

And see, that nothing can be known!

That knowledge cuts me to the bone.

I'm cleverer, true, than those fops of teachers,

Doctors and Magisters, Scribes and Preachers;

Neither scruples nor doubts come now to smite me,

Nor Hell nor Devil can longer affright me.

_edit, tl;dr from britannica.com:

Faust, also called Faustus, or Doctor Faustus, hero of one of the most durable legends in Western folklore and literature, the story of a German necromancer or astrologer who sells his soul to the devil in exchange for knowledge and power. There was a historical Faust, indeed perhaps two, one of whom more than once alluded to the devil as his Schwager, or crony. One or both died about 1540, leaving a tangled legend of sorcery and alchemy, astrology and soothsaying, studies theological and diabolical, necromancy and, indeed, sodomy. Contemporary references indicate that he was widely traveled and fairly well known, but all observers testify to his evil reputation. Contemporary humanist scholars scoffed at his magical feats as petty and fraudulent, but he was taken seriously by the Lutheran clergy, among them Martin Luther and Philippe Melanchthon. Ironically, the relatively obscure Faust came to be preserved in legend as the representative magician of the age that produced such occultists and seers as Paracelsus, Nostradamus, and Agrippa von Nettesheim.

     -  -  -  
Goethe’s play, which contains an array of epic, lyric, dramatic, operatic, and balletic elements, ranges through various poetic metres and styles to present an immensely varied cultural commentary that draws upon theology, mythology, philosophy, political economy, science, aesthetics, music, and literature. In the end Goethe saves Faust by bringing about his purification and redemption.

jobstijl··on Lessons from the Novena laptop project
Andrew "bunnie" Huang is working on the novena and is also on the Technical Advisory Board of lowRISC - a core based on the RISC-V instruction set. So I guess that there is quit a chance they will use RISC-V in the future.

jobstijl··on Geographic variation in the prevalence of ADHD (Circadian and sleep aspects)
Here is more information: http://www.brainclinics.com/association-adhd-intensity-sunli...

A study published today in Biological Psychiatry sheds new light on the increasing rates (prevalence) of attention-deficit/hyperactivity disorder, known as ADHD. Children with ADHD have problems with inattention, distractibility, disorganization, impulsiveness, and overactivity. This study found that “sunny” regions with high solar intensity, such as the US states of California, Arizona, and Colorado, and countries like Spain and Mexico have lower prevalence of ADHD. An apparent protective effect of sunlight accounted for 34-57% of the variance in ADHD prevalence. The authors speculate that this may be related to sunlight’s effects on preventing circadian rhythm (“biological clock”) disturbances. These results suggest ways to prevent or treat ADHD for a substantial sub-group of patients.

jobstijl··on An open source prosthetic hand costing $1000
This looks good. I don't have my left hand from birth and did try a prosthetic hand in the nineties. Then i found them to heavy and 'stupid' to use. This is something I definitely would like to try.
