rsecora··on Astra for Law
XIX century dickensian society and Gilded Age barons were replaced by the time of the New Deal.
rsecora··on Astra for Law
If we have enough energy and raw materials to keep building, yes, it will be an utopia made real. But if there is energy scarcity, then other two outcomes can arise.
rsecora··on Pyscripter – Open-source Python IDE written in Delphi

rsecora··on A Software Development Methodology for Disciplined LLM Collaboration
Back in the day, when business computing emerged (COBOL, Mainframes...), it appear the distinction between systems analysts and programmers. Analyst understand business needs, programmers implemented those specs in code.

Years later, the industry evolved to integrate both roles, and new methodologies and new roles appear.

Now humans write specs, and AI agents write code. Role separation is a principle of labor division since Plato.

rsecora··on Giving people money helped less than I thought it would
Results for Group A (1000$/m) closely resemble results for control Group C(50$/m). Metrics like % of Unsheltered participants, change in full-time employment, % of participans in a house they rent or own... have a diference of 1 or 2 points.

Thats the point of the author, those are minimal variances, and insuficient to claim inpact due to basic income.

Personal opinion. The study itself exert a nontrivial influence on participants. The act of being engaged, regular check-ins... affect positively. Their lives improve independent of the financial component because they are part of the study, not because of the amount of money in the procedure.

rsecora··on Classic Common Desktop Environment coming to OpenBSD
I was surprised when the 64bit fork appears in github.

The OpenLook 64bit fork is available at [1], it has 64bit & X11R7 patches. It has a miriad of changes related to ids sizes, %ul, function casts, and a migration from X11R4 to X11R7.

Sadly, if a legacy applications is old enough to be linked to OpenLook, it surelly require adaptation. They need their own migration to transition to 64 bits and X11R7. This openlook fork is the start of the journey to resurect them.

rsecora··on Found a simple tool for database modeling: dbdiagram.io
I usually go with the FOSS https://pgmodeler.io

Its feature-rich, albeit focused on Postgres. And it's ability to compare database schemas makes updating and applying diffs much easier.

rsecora··on Winners of the $10k ISBN visualization bounty
The dataset consists of books from the Anna Archive, each identified by an ISBN. The ISBNs and titles are extracted from datasets [1], which include magazines and books primarily in Chinese, English, and French.

Example: Germany publishes five times more books than the Netherlands [2], and Spain publishes twice as many books as the Netherlands. However, in visualizations, Germany appears similar to the Netherlands, while Spain and Mexico do not aligned with the high-level labels [3].

rsecora··on Visualizing all books of the world in ISBN-Space
Impressive presentation.

Note: The presentation reflects the contents of Anna's archive exclusively, rather than the entire ISBN catalog. There is a discernible bias towards a limited range of languages, due to Anna's collection bias to those languages. The sections marked in black represent the missing entries in the archive.

rsecora··on The Chorleywood Experiment (2023)
TLDR;

The Chorleywood bread process is a method of dough production to make yeasted bread quickly, producing a soft loaf. It allows the dough to be made with lower-protein wheat and it uses more yeast, added fats, chemicals.

80% of all the bread made in Britain, Australia, New Zealand and India, use the process.

rsecora··on A History of Source Control Systems: SCCS and RCS
Maybe you are asking about TeamWare [1]. It was the Sun Microsystems VCS based on SCCS and using NFS.

There exists an abundance of resources related to TeamWare. From online documentation [2], to patents [3]...

rsecora··on Why is Maxwell's theory so hard to understand? (2007) [pdf]
Its 99 years since Einstein published the paper on the photoelectric effect whith had far-reaching consequences. [1]

And 93 years since the first Solvay Conference. [2]

rsecora··on Z80 vs. 8088 Speed
The 8088 has a external 8 bits bus. The performance improvement hardware 16 bits ALU is neglected by the slower memory access.

And that memory access was also the reason a 6502 carefully programmed will have better performance than a 8088 with 5x the clock speed. The first 256 bytes (0 pages) had better access performance.

rsecora··on FreeBSD 14.0 has reached – RELEASE
1. Servers

2. Better net throughput & lower CPU usage & ZFS. Y also really love the release eng cycle and release notes.

3. Using FreeBSD since 2001. Some performance test back then, better documentation...

4. A solution similar to docker.

5. ZFS

rsecora··on Andrew Ng on AI Applications and the Defense Production Act
Thas the point of Andrew Ng.

"While the White House order isn’t currently stifling startups and open source, it seems to be a step in that direction"

rsecora··on Global CO2 Levels
it starts 1958 because it changes the source [1]. Before 1958 law dome & ice cores. After 1958 air measurements at Mauna Loa Observatory, Hawaii.

rsecora··on Global CO2 Levels
For those wondering why there is zig zag in the plot after 1958. The data source changed at that date [1].

  * 1000 - 1958: Historical CO2 record from the Law Dome DE08, DE08-2, and DSS ice cores

  * 1958 - Today: in situ air measurements at Mauna Loa, Observatory, Hawaii.

rsecora··on Ask HN: Is middle management the most vulnerable/disposable in a corporation?
The bureaucracy is a well-oiled machine on its own. It has a self-perpetuating nature, following its own set of survival rules, just like the principles of evolution by Darwin.

There's a classic book called "The Bureaucratic Phenomenon" that delves into this very phenomenon. Interestingly, middle management doesn't exactly boost the value of the products or outputs, but it keeps growing to cater to its internal demands and desires.

rsecora··on My Overkill Home Network
Cool

but is astonishing how expensive is the connectivity in other countries.

>>> Verizon Gateway sitting on top of the rack. I get pretty good signal here and get the rated speed, of around 300Mb/s down and 20Mb/s up. This costs $50/mo.

There are offers [0] in the EU of 10Gbps / 25 Euros/mo.

rsecora··on Lisp in Space
I'd love to hear more about your side projects if you wouldn't mind.
rsecora··on Ask HN: Is anyone using PyPy for real work?
I use it for data transformation, cleanup and enrichment. (TXT, CSV, Json, XML, database) to (TXT, CSV, JSON, XML, database).

Speed up of 30x - 40x. The highest speedup on those that require logic in the transformation. (lot of function calls, numerical operations and dictionary lookups).
