rubinelli··on Docker Compose Isn't Enough
I may consider using HOCON [0] if I see any traction, bust after writing a lot of YAML and even making my own YAML-driven tools, I feel its shortcomings are overstated. I got bit by corner cases maybe three or four times, and they didn't take long to debug.

[0] https://github.com/lightbend/config/blob/main/HOCON.md

rubinelli··on DuckDB over Pandas/Polars
I've written a fair bit of PySpark code and Polars's syntax feels fairly similar, but it also offers a limited SQL dialect.
rubinelli··on Why GitHub won
Anything besides ads, GCP, and Apps in that bucket?
rubinelli··on Ask HN: Why did Python win?
Perl's actually excellent at processing unstructured data, and it had a strong foothold in bioinformatics for a time. I don't think the decision was as obvious as it looks.
rubinelli··on A new method to reprogram human cells to better mimic embryonic stem cells
That's a very rosy view of humans. The average person gets older, not wiser; they see the consequences of their actions and find someone else to blame. Real social and cultural change comes from new generations.
rubinelli··on A new method to reprogram human cells to better mimic embryonic stem cells
CGP Grey doesn't explore what happens after death is defeated. I can't imagine how it can lead to anything but a stagnated society, with prejudices and inequalities enshrined forever.
rubinelli··on AI is in danger of being swallowed up by copyright law
De minimis is a longstanding defense in copyright law. If you are copying very little from very many works, as is the case when you turn multiple petabytes into a few gigabytes of neural network weights, you are in the clear. The problem arises when models overfit and spit out almost perfect copies of the training data.
rubinelli··on Rowan Atkinson: Visual Comedy (1992) [video]
Early Lego games made great use of intonation and miming for their gags and storytelling. For example, this is their version of the famous "I am your father" scene: https://www.youtube.com/watch?v=fvX3MaFB9TI
rubinelli··on The Grug Brained Developer
There is a lot of wishful thinking that goes into galaxy brain code. It assumes you know with almost complete certainty what rules are bound to change and where extension will be needed, that the next developer will be able to understand and respect the beautiful elegance of the design instead of hacking at it to achieve the desired result, and that the code will be long-lived enough to justify the initial investment. Grug coders aren't always inexperienced; many are actually repented architecture astronauts.
rubinelli··on Does the Tank Have a Future?
Aircraft carriers don't have the large cannons of a dreadnought. An armored car that served as launchpad and command center for drones could be drastically lighter, faster, cheaper, and with simpler logistics.
rubinelli··on The 1980s Media Panic over Dungeons and Dragons (2016)
There was a fair bit of moral panic, funnily enough, around D&D recently, specifically the representation of "evil" humanoid races and how they mirrored real-life racism https://www.psychologytoday.com/nz/blog/checkpoints/202004/n...
rubinelli··on The 1980s Media Panic over Dungeons and Dragons (2016)
Is it just a moral panic? Because these kids, who are bright enough to build their games and virtual worlds in Roblox's arcane tools, are spending hundreds of hours to create content for a multi-billion company and seeing nothing for their efforts. (In fact, many spend money to promote their worlds, so they are paying to work.)
rubinelli··on I Don't Want to Be on Call Anymore
You should also be compensated for the time you spend on-call (which means you can't take on other commitments you otherwise might.) Anything less and it's outright exploitation. "We pay you well" is a non-sequitur.
rubinelli··on Why Carbon Taxes Work
Most messy problems can't be solved by neat solutions. Without tariffs, countries will be incentivized to use lax emission control as a competitive advantage.
rubinelli··on Bitcoin is a Ponzi
That's not true. It's fantastic for ransomware and scams in general.
rubinelli··on Alabama Had More Deaths Than Births in 2020
Nope. The world didn't keep a control group for smallpox, even in the most distant villages. We simply eradicated it.
rubinelli··on Alabama Had More Deaths Than Births in 2020
Even though we talk about "the" vaccine, there isn't only one; there are half a dozen different vaccines being administered world-wide, using different methods of production. We're talking about all these independently-developed vaccines failing catastrophically in a way no other vaccine has ever failed before -- reactions after two weeks are incredibly rare. We're thousands of times more likely to be wiped out by a meteor.
rubinelli··on u/DeepFuckingValue and the GameStop Reddit mania
Funny, but it suggests the market hasn't learned anything from 2008.
rubinelli··on The Mark Cuban Cost Plus Drug Company
People keep talking about patients going to the doctor for frivolous reasons, but what I see is that it is much more common for patients to ignore symptoms or take some over-the-counter medicine, and take too long to see a doctor.
rubinelli··on We Crush, Poison, and Destroy Insects at Our Own Peril
I think there is a lot of good to talk about, with just a little creativity: hundreds of thousands of jobs in a green economy, cleaner cities, ending the dependence on oil from autocratic nations, devices that you can repair and use for decades instead of discarding after eighteen months. You will never convince people to willingly downgrade their standard of living, but you can convince them to side-grade. Can you convince billions of people to turn vegan? Probably not, but you can convince them to eat synthetic meat, specially if it is cheaper, safer, and more consistent than beef from a live cow.
rubinelli··on Sales of electric cars up by 43% in 2020
Many of the innovators in medieval Europe and Soviet Russia were seen with suspicion, when not outright persecuted. Innovation, beyond safe incremental productivity improvements, requires nonconformism and unconventional thinking. After all, why would you create something new if you are content with what you have?
rubinelli··on The Paradox of Abundance
In this case, the irony comes from selling a product that will probably make the problem worse by teaching people how to pump out articles faster and add to the information glut.
rubinelli··on [dead]
Exactly. Every country affected by COVID-19 saw an enormous surge of deaths by respiratory diseases. Here in Brazil there are signs that we may be underestimating both infected and deaths by a factor of ten.
rubinelli··on God be with you till we meet again (1918)
Given how contagious it is and how much faster information moves today, that is highly unlikely.
rubinelli··on What happens to all the old wind turbines?
Fiberglass would break down and release microplastics, though, so it is not as environmentally friendly as a sunk metal hull.
rubinelli··on A billionaire retailer whose shops had no stock
I was a child at the time, but I remember salaries, prices, taxes, everything followed an index, the URV (real value unit). The index then became the Real we have today, and indexation was abolished. So businesses had something reasonably stable to base their finances. Still, the queues at markets on payday were enormous, since most workers would go buy groceries for the whole month as soon as they got their salary.
rubinelli··on Why we've never fallen in love with virtual reality
You don't need VR for that, only motion controls. Some people have exercise streaks that go on for years on Nintendo's Wii Fit, and Ring Fit Adventure is on the same path.
rubinelli··on For suicide prevention, try raising the minimum wage, research suggests
If nobody is taking that job for a salary that is economically viable, then it shouldn't exist. We shouldn't make people waste their finite time on this Earth doing pointless jobs under the threat of homelessness or starvation.
rubinelli··on 3D Buzz has closed its doors and distributed all its material free of charge
A redditor created a torrent with the full content: https://www.reddit.com/r/DataHoarder/comments/el4ghb/3d_buzz...
rubinelli··on Your cyberpunk games are dangerous (2015)
It was translated to Portuguese by Devir in the early nineties, and I distinctly remember a sidebar discussion on whether separate wide-area networks would eventually join to become "the Net." It was the first time I saw the word Internet.
