vletal··on Germany locks down unvaccinated people, as leaders plan to make shots compulsory
You feel like Germany is lacking basic strategy?

I'm Czech and we wish here we would be as prepared and forward thinking as your representatives are. If it was not for one of the highest rate of ICU beds per capita in the world and all the high quality nurses and doctors we export to Germany, our health care would have already crumbled.

vletal··on Pybaobab – Python implementation of visualization technique for decision trees
So was the Little Prince applying daily regularization to the baobabs on his planet?
vletal··on Nature Is Becoming a Person
It's a role not a responsibility. Responsibility would imply that they can be hold accountable for not delivering. Such as blaming plants for not taking enough CO2 from the atmosphere.
vletal··on Julia 1.7 Highlights
Yeah, I should not have used "increasingly", yet what you are pointing out is an example of an improvement in a single module, not the language compiler & llvm. It does not actually prove the original comment wrong.
vletal··on BetrFS: an in-kernel file system that uses Bε trees to organize on-disk storage
Oh, thx for pointing that out. I was not aware of the other possible pronunciations.
vletal··on BetrFS: an in-kernel file system that uses Bε trees to organize on-disk storage
Is it that bad? There is plenty of technical shortcuts which differ in a single letter - that should not be an issue. Plus one is pronounced /ˈbiːtriː/ and the other likely /ˈbɛtə/ (or /ˈbɛtəɹ/ in the US :)).
vletal··on Julia 1.7 Highlights
> The performance Julia provides without interfacing C/C++ or Fortran is not just a convenience, it has architectural consequences.

These statements set the expectations really high. Yet they omit the ugly truth of increasingly slow compilation times, pure compilation caching, JIT which might affect overall performance due to type instability.

Yeah, like Haskell has a nice Quick-sort example prominently displayed at the front page, Julia is sleek for scientific computing, yet it can bite you really bad as soon as you start wrapping the developed model into a real world REST app.

Do not get me wrong, I see some of the benefits of Julia. On the other hand, I do not think this uncritical hype about "coding 'further'" does good for the language.

vletal··on Classification of Omicron (B.1.1.529): SARS-CoV-2 Variant of Concern
Omicron? Was not it Nu like few hours ago? I like the longer name better. Our ministry of finance has already made a typo in a Facebook post calling it Mu (like the sound cows make).
vletal··on Heavily mutated coronavirus variant puts scientists on alert
Maybe colors of PacMan ghosts then?
vletal··on Heavily mutated coronavirus variant puts scientists on alert
Is Nu /ˈnjuː/ (en) /niː/ (cz) a good name? I assume that most people have heard first few letters of Greek alphabet. Yet after Delta they should have switched to Pokemon names. Would be much more robust. I can already imagine all the misspelling in Twitter rants.
vletal··on B.1.1.529
Your answer seems to assume that the distribution of spike proteins which binds to the ACE is very close to the one for which we obtain immunity by getting vaccinated.

Yet we can already see that Delta binds better than the early strains and the efficacy of existing vaccines against it is like 60%, which contradict that. Does it make sense?

vletal··on B.1.1.529
Hopefully not worse. The current assumption seems to be that it could be different enough to avoid existing immunity gained against previous strains.
vletal··on An engineer's observations on Web3 and its possibilities
I kind of expected that we are talking about the basic mobility, such as my wife coming from a low income blue collar family becoming an upper-middle class architect. Not the chance of becoming a super-rich or super-powerful.
vletal··on An engineer's observations on Web3 and its possibilities
You are cherry picking outliers to argue against a claim about a general trend.

It really does not matter how hard this or that particular individual worked. What matters is statistics which describes the opportunity of an anonymous Joe in the society.

vletal··on GC progress from JDK 8 to JDK 17
I like how this reached the top page soon after "Go does not need a Java-style GC" (https://news.ycombinator.com/item?id=29319160).

Moreover, are the significantly lower GC pause times help improve snappiness of GUI apps, such as IntelliJ IDEA?

vletal··on An engineer's observations on Web3 and its possibilities
I can clearly see a strong correlation between both education and hard work vs. social status and income. I come from Europe though. Is it really not the case in the US? Is it because of student loan barrier?
vletal··on Tech investors can’t get enough of Europe’s fizzing startup scene
We'll, the claim seemed overly broad. I wanted to point out that these harsh liabilities on the side of company directors are country specific and usually a company can go bankrupt as long as it's not the fault of the director due to them mishandling the company resources without pulling the director down with it.
vletal··on Tech investors can’t get enough of Europe’s fizzing startup scene
Ltds are a common thing all around the world and work as you'd expect. What OP mentions seems to be specific to Portuguese law.
vletal··on Fingerprints can be hacked
The title almost sounds like that they have a meaningful fingerprint ready to open her iPhone... Was that the case? Or do they have a somewhat accurate partial fingerprint? I failed to find recoding of the presentation.
vletal··on Advent of Code 2021
I almost got an heart attack while seeing this post. Still dizzy from waking up early I thought it was already December.
vletal··on Goodbye, Clean Code (2020)
Is it really the case? Could it maybe be that these clickbeity titles are upvoted and comment on more, regardless of the questionable added value to the community "burried" deep inside?
vletal··on Corded headphones are making an unexpected return
I am used to wearing wired Apple earphones all around with me. I often listen while biking or riding an EUC. I simply must hear the surrounding traffic. These earphones let just enough ambient sound to pass trough yet they have a superior sound quality compare to other "OEM" headphones. Moreover, IMO the mic recordings sound just much better as well compare to earphones when used outside while passing around morning traffic.

At last, I got an ear infection from wearing plugs in the past. Since then any plugs start irritating my left ear very quickly. I basically can not comfortable wear plugs in my ears for more than a few minutes anyway.

vletal··on Packages dumped in wrong lobby, resident tried harder to correct it than Amazon
Btw. fun cultural difference: In some other countries it's not considered Ok to keep packages on front porches or next to mail boxes. Drivers in the Czech Republic would never leave package like that and hence it would be their mistake not Amazons/Bazoses.
vletal··on Pyjion – A Python JIT Compiler
> Some benchmarks have a slow max/mean value because the time includes JIT-compiling large libraries like Pandas.

So why do not they warm the JIT up first? Moreover the graph does not contain any notion of mean/max values at all. Any idea where I can see a more comprehensive benchmark?

vletal··on Ask HN: Why are monitors lagging behind in tech?
Smartphones started from scratch supporting displaying the same content on displays with various sizes and DPIs. Computer apps and window managers were long stuck with bitmap / pixel perfect UI frameworks.

There was little to no demand for displays above HD before Apple gave devs the incentives to make their apps support HiDPI by introducing retina displays. Windows took really long time to offer similar support. Linux was (is?) waiting for Wayland to solve this issue.

vletal··on iPhone apps can tell many things about you through the accelerometer
Sure, but the article makes it seem that this is a thing done in a wild on a mass scale which is implausible.
vletal··on iPhone apps can tell many things about you through the accelerometer
How does it relate to the paragraph about pinpointing precise location which the original comment refers to?
vletal··on iPhone apps can tell many things about you through the accelerometer
> Now, if this social app is reading accelerometer data on your phone as well as the passenger’s phone, the app can easily figure out that both phones experience the same vibration pattern. ... Don’t be surprised if you receive a recommendation from the app to add this passenger as a friend.

Overall I find the article interesting but this quote is borderline tinfoily. Given the amount of noise in the accelerometer data and signal s much closer to the sensor than the bus itself - such as body movements, it would be hardly precise. Moreover the cost of doing all that research and computation as well as data transfer would hardly pay off.

vletal··on San Francisco's homelessness is a humanitarian crisis
Sure it would. Yet not to the full extent. The system is complex, not all people rent, not all home owners would be hit by the tax equally, ...
vletal··on 55 GiB/s FizzBuzz
That does not actually contradict the point. We got stuck in a suboptimal local maxima due to the all early design decisions of browsers and JavaScript. The original inventors did not expect anyone wiring web version of Google Drive on the web.

The market surely pushes against the bloated electron apps, yet the convenience of having the same app on web as well as "native" and the amount of man years which went to make HTML+JS the richest multi-platform UI framework on the market is more important.
