rejschaap··on Hospitals mergers do not improve quality: study
For mergers the best case scenario is probably quality remaining at the same level.
rejschaap··on Terrain rendering algorithm in less than 20 lines of code
Brings back memories of playing Novalogic Comanche with a Logitech WingMan Extreme. It was an amazing experience at the time. That game was really far ahead of its time.

I really like the animations that illustrate how the algorithms render the final result.

rejschaap··on Predictions for 2020–2029
> A decade is a period of 10 years.

Technically, every year is the end of a decade.

rejschaap··on Scaling React Server Side Rendering
React is component based, this allows for a level of encapsulation and reusability that cannot be achieved with Razor. You might not truly appreciate this until you try out React.

If you don't want to dig too deep though, compare how to add a datepicker to a view in both systems. With React it is just another component, with Razor it is a bit more finicky.

rejschaap··on Non-Rectangular Video Cropping with FFMpeg
It has some aliasing artefacts around the edge of the circle, you can see it very clearly during the fade-in. When the video is playing you don't really notice it. My guess is that this is caused by the way the mask is created. I can't try it out right now, but it could probably be solved by setting the RGB channels of the mask image to black.
rejschaap··on Ask HN: What do you know about bitemporal databases?
I don't see how a spreadsheet is either bitemporal or a database. But you could do some simple bitemporal modeling in a spreadsheet. I would imagine querying to be extremely limited and cumbersome though.
rejschaap··on Jeff Dean interview: Machine learning trends in 2020
Is Jevons paradox really a problem when your carbon footprint is zero?

> VentureBeat: One of the things that’s come up a lot lately, you know, in the question of climate change — I was talking with Intel AI general manager Naveen Rao recently and he mentioned this idea [that] compute-per-watt should become a standard benchmark, for example, and some of the organizers here are talking about the notion of people being required to share the carbon footprint of the model that they trained for submissions here.

> Dean: Yeah, we’d be thrilled with that because all the stuff we trained in our Google Data Center — the carbon footprint is zero.

rejschaap··on If this project is dead, just tell us
The 0 commit project is dead or finished.

The 669 commit project is clearly not finished, but also not really dead, yet.

rejschaap··on Ask HN: What tech choices make “new” Reddit so unbearably slow?
> They also were open source for a long time but closed it like 2 years ago.

Makes me wonder why, to protect their amazing IP, or was the code base just getting too embarrassing to look at?

rejschaap··on Symantec Is Now NortonLifeLock
Norton Commander was great too and Peter Norton wrote the book on programming the IBM PC.

IIRC Norton AntiVirus was a rebranding of Symantec's antivirus software and probably the first usage of Norton's name for marketing reasons whereas NortonLifeLock is the last.

rejschaap··on A CS degree is better than teaching yourself how to code?
Upvoted, I think people don't really understand how little time is spent on actually learning to program in an average computer science degree. If you don't study programming yourself and have intrinsic motivation to do so, you really can't program all that well despite having a CS degree.
rejschaap··on Dutch MoD appoints 72 citizens to cyber-military reserve force
Plaintext would have sufficed
rejschaap··on “May You Live in Interesting Times”
Filet Americain is based on steak tartare. And American sauce is based on Thousand-Island dressing. They are adapted to local taste and customs, but they would be somewhat familiar to Americans.
rejschaap··on Ask HN: What's a promising area to work on?
Also have a look at Zimbabwe where climate change is already seriously compounding existing problems. The poorest are hit the hardest.

rejschaap··on My Repo, My House, My Rules
> I’ve recently realized people misguidedly think GitHub repositories are public space.

I feel it is quite similar to public space. It is open and accessible to everybody. There is a certain etiquette in public space that you should adhere to though. I think that is where the real issue lies. A few people have unrealistic expectations of open source maintainers. I have seen very rude behavior towards maintainers, people get this weird sense of entitlement sometimes.

rejschaap··on How to pack a Norwegian sandwich, the world’s most boring lunch
It seems there are three types of people based on what they deem most important regarding the meals they consume. There are people who primarily eat for sustanance, there are people who eat for pleasure and there are Americans.

I'm solidly in the sustance camp, I tend to go for quick, easy and nutritious. Occasionally I will splurge and eat out at a good restaurant and enjoy it a lot. My wife is in the pleasure camp and doesn't want to waste any opportunity to have a delicious meal and even hates to have a simple breakfast or lunch. My three year old son might be an American, he just wants to eat McDondalds three times per day.

rejschaap··on Social Networks That Failed
> enthusiasts of Abercrombie & Fitch

What a bunch of weirdos...

rejschaap··on Show HN: uPlot.js – An exceptionally fast, tiny time series chart
There is a list of alternatives in the performance benchmark you could check out:

https://github.com/leeoniya/uPlot#performance

Personally I use highcharts a lot, it has many chart types out of the box and allows for enough customization to fit my needs.

rejschaap··on Ex-World of Warcraft developer's thread about China and the gaming industry
People have a tendency to remember games from their childhood more favorably. World of Warcraft and StarCraft 2 were very high quality games. Obviously the business model had to change, we don't live in the 90's shareware world anymore.
rejschaap··on Robots to Cut 200k U.S. Bank Jobs in Next Decade, Study Says
Cost reduction sounds like a natural thing for a business in a healthy market economy.
rejschaap··on Prashanth Chandrasekar Replacing Joel Spolsky as Stack Overflow CEO
That's not my experience at all, what is the number one source for you and which tech stack are you working in?
rejschaap··on Belgian police forced to stop using facial recognition (Dutch)
The article is about the airport, not about the town. The airport is often called Zaventem because of its location. International travelers will know it by the name Brussels airport.
rejschaap··on Kiss – A Linux distribution with a focus on “less is more”
This distro is much simpler than Arch. It reminds me more of something like Static Linux: https://sta.li/
rejschaap··on Why is Rust slightly slower than C?
That depends on the purpose of the comparison. But for many practical reasons you are right.

It makes this statement seem a bit dishonest though:

"Our Rust driver is a few percent slower than our C driver, why? Well, it's of course because of safety features in Rust, but can we quantify that?"

rejschaap··on Sunsetting Mercurial Support in Bitbucket
It wasn't mandatory, actually. It was possible to turn off the locking. But that was like entering a whole new world of pain. So most people didn't dare turn it off.

They called it "multiple checkout", and the manual strongly recommended you do not turn it on.

The software had issues with corruption due to operations not being atomic.

rejschaap··on The Invincible – 1964 novel
The direct translation by Johnston from 2006 is not good? The more negative reviews on Amazon don't seem to mention the translation much.
rejschaap··on A Novel Concept: Silent Book Clubs Offer Introverts a Space to Socialize
> An unpopular opinion that I'm sure will garner negative reactions because everyone likes to self diagnose themselves, but I find the introvert/extrovert dichotomy quite weak.

Most psychologists don't view it as a dichotomy but rather as a scale with introversion on one side and extraversion on the opposite side. People are not either introverted or extraverted, they are somewhere on this scale. Which means that they tend to prefer introverted or extraverted behavior depending on their position on the scale. So even a very introverted person can display extraverted behavior, although it will be unlikely to happen often.

> Most people who I meet who proclaim they are "introverted" have just not invested any time into building their social skills.

The further people are on the introverted side, the more they prefer to be by themselves. Any skill you don't practice will not improve much, this is also true for social skills.

> Deciding which one you are by taking a shallow survey with surface level questions seems unintelligent.

> Choosing one to identify with seems irrationally limiting to who you could be.

You can influence the outcome of the survey, but the idea is to determine where you are on the scale, not to decide or choose. It is a model of personality/temperament and has proven itself quite useful over the years. But obviously it has its limitations.

rejschaap··on Jeffrey Epstein: Financier 'found dead in cell' in New York
There was an earlier attempt or incident and he was on 'suicide watch'.
rejschaap··on Jeffrey Epstein Pitched a New Narrative. These Sites Published It
No, people call them fake news because they do not like the facts that are reported.
rejschaap··on What if you couldn’t program with loops?
Agreed, that is a much better direction to go.

In this particular case you could combine map with filter instead of hiding the filter inside "action"
