zakk··on Think Legroom on Planes Is Bad Now? It’s Going to Get Worse
I am much taller than average, way above the 99th percentile.

In some airlines I simply cannot seat, as my legs don’t fit. Sometimes flying is physically painful.

I don’t see why making passengers extremely uncomfortable should be a good thing.

If you think flying is bad maybe you should find some other ways of disincentivizing it, rather than making people that might be flying for legitimate reasons extremely uncomfortable!

Again, you are factually wrong.

The first active repository in the list I just linked to you is used for nuclear wastes from a nuclear power plant. I just checked the first, there will be more if you just take the time to get informed.

Get your facts straight.

zakk··on I just had over a thousand Euros stolen and Revolut is siding with the thief
And that's why you should get a credit card from a real bank, rather than a debit card. With a credit card, in case of fraud, the bank will most likely side with you.

(Talking about Europe, not sure the same applies outside Europe, for instance the American banking system is quite different...)

> No, there are none.

According to Wikipedia there are many currently in operation:

https://en.wikipedia.org/wiki/Deep_geological_repository#Rep...

Is Wikipedia wrong?

zakk··on Climate protesters storm Garzweiler coal mine in Germany
> And yet, not a single facility like that exists anywhere

That's factually wrong. There are several deep geological repositories currently in operation.

> in germany we do not have a long term storage solution that can safely withstand over 1000s of years for nuclear waste.

A much simpler problem to solve as compared to other challenges due to climate change.

You can build a storage big enough to contain all radioactive waste from current and future nuclear power plants probably in less than one year.

I should assume you never travel by airplane since there have been some disasters?

Truth is that nuclear energy is the safest form of energy.

and nuclear.

zakk··on Terminus: a configurable terminal emulator for Windows, macOS and Linux
100 MB for a terminal emulator? Debian's package for xterm is 200 times smaller, but OK, let's try...

Google Analytics? Thanks, I'll pass on this one!

zakk··on BGP 768K day, and whether it will cause internet outages
> Many ISP and other organizations had provisioned the size of the memory for their router TCAMs for a limit of 512K route entries, and some older routers suffered memory overflows that caused their CPUs to crash.

> Engineers and network administrators scrambled to apply emergency firmware patches to set it to a new upper limit. In many cases, that upper limit was 768k entries.

Is there some technical reason for the emergency patch not to have increased the limit to a much higher and future-proof threshold?

In 2014 it shouldn't have been hard to predict that the new 768k would have been hit in just a few years.

zakk··on The Human Brain: Even Basic Facts Are Hotly Contested
> Even in your ideal experimental scenario, the laws of probability state that before the 10,000,000,000th such study is completed, we will see a case where the findings turn out to be incorrect.

And yet by means of statistics one can model the errors, and obtain an experimental measurement with 10 significant digits.

And, guess what, it agrees with the theory! Ten. Significant. Digits.

> Logic may be an exception by virtue of it's mathematical nature, but any facts involved are not, and we fall back on judgement calls most of the time even when we think we're being logical.

That's not how Science works.

zakk··on The Human Brain: Even Basic Facts Are Hotly Contested
The fact that an artificial neural network (which very roughly mimics human brain) is probabilistic in nature does not have any implication for Science as a whole.

Science can make predictions that are extremely accurate (think ten significant digits) and the uncertainty on that prediction (i.e. the eleventh significant digit) does not have anything to do with neural networks or us being "probabilistic creatures", whatever that means.

zakk··on Apple Rumors Point to 31.6-inch 6K Display, All-New 16-inch MacBook Pro for 2019
Don't give them ideas, please!
zakk··on Homebrew 1.9.0
That's the exact reason why I consider MacPorts much more elegant.
zakk··on The New Brave Is 22% Faster
From the linked article:

> Note that we are comparing released versions; Brave 0.24.0 is based on Chromium build 69.0.3497.100, while Brave Core 0.55.12 uses a newer Chromium build 70.0.3538.45. We do not expect the move to a later underlying Chromium version to be responsible for significant performance variations. We don’t observe a statistically significant difference for unthrottled measurements—in fact, Chrome 70 is sightly slower for the sites we considered.

zakk··on String tokenization in C
That’s not a good reason not to use it.

A function can be not thread-safe and still safe to use in single-threaded programs.

The point is that strtok is not a good choice even for single-threaded code.

zakk··on Linux Kernel Developers Discuss Dropping x32 Support
If you code does intresive computation with structures containing a lot of pointers, you’ll get much more cache miss when using 64 but pointers.

The performance hit can be quite heavy!

Cache is a limited resource, and you want as many pointers as possible to fit there.

zakk··on How the Finnish survive without small talk
I also learned it the hard way, but coming from the other extreme.

I grew up in Italy, where asking “how are you doing” is not uncommon. Only difference: people actually expect a short summary of what you’ve been up to...

zakk··on Ask HN: What is it like to run a VPN as a business?
That’s a good idea, but usually Netflix can blacklist domains faster then a VPN provider can acquire new “residential” blocks.
zakk··on Hardening macOS
Thanks for the nice guide. I wouldn’t use Google DNS as a default though, they don’t have a good record when it comes to respecting privacy.
zakk··on Titans of Mathematics Clash Over Epic Proof of ABC Conjecture
Euler identity looks very bizarre if you don’t understand the proof. Why should exponentiation, the imaginary unit and pi be related?

In mathematics there’s absolutely no place for judging the bizarreness of statements, either they are right or wrong, and of course such a judgement cannot be made by someone who admittedly doesn’t have the necessary background.

As I already said, often in the Academia saying that a result is bizarre is a not-so-subtle way of implying something is wrong by appealing to authority.

zakk··on Titans of Mathematics Clash Over Epic Proof of ABC Conjecture
When the world's most brilliant mathematician (or at least one of the most brilliant) says "it would be rather bizzarre if your argument worked" the implications are absolutely clear.

As a scientist I would never make such a statement, moreso for a theory I admittedly don't understand.

Tangentially, it's not Tao's case, but I have seen a lot of bullying in the academia along these lines... "I am not saying it's wrong, just very bizzarre", "I am not saying it's wrong, but my Ph.D. student worked on it for two years and couldn't solve it", "I am not saying it's wrong, actually I don't even understand the details, but please recheck everything..." etc...

zakk··on Titans of Mathematics Clash Over Epic Proof of ABC Conjecture
Well, in science there’s a simple rule: your substantiate your claims.

A plausibility argument like Tao’s one is simply not an argument.

To show that Mochizuchi is wrong you need to point out which equation of his work is wrong, which by the way is Peter Scholze’s plan.

Tao by his own admission does not have the background to evaluate Mochizuchi’s theory and still gives this worthless plausibility argument, appealing to his knowledge of other unrelated proofs. I’m astonished.

zakk··on Titans of Mathematics Clash Over Epic Proof of ABC Conjecture
To me it sounds more like: I don't like the idea of this theory working, but I don't have a refutation.

Honestly I am surprised of hearing such an argument from one of the world's best mathematicians.

zakk··on Why should I use DuckDuckGo instead of Google?
Maybe you are right, but it's quite pointless in this context to judge someone's intentions.

Staged or not, if Gabriel's answer is factually accurate -- as it seems to be from a cursory look -- I don't see a problem here.

zakk··on User banned from Das Keyboard forums for telling people of open-source drivers
That’s absolutely not true in my experience (mostly around Europe).
zakk··on Reddit Security Incident
> People keep all kinds of stupid shit in home directories. SSH keys.

Are you implying that it's stupid to keep SSH keys in one's home dir?

> You can hear the stories about companies not hiring women when they are in a relationship and in the age when they are more likely to have kids.

That's discrimination, and is a legally prosecutable offense in many countries.

Unfortunately it still happens, but we are putting an effort in making sure it happens less and less.

> said the decision was driven largely by concerns for the environment

This has a potential for starting a lifestyle inquisition.

The single worst thing one can do for the environment is to have a child. Does WeWork plan to fire you should you decide to reproduce?

Also, what about people having vacation overseas, when exploring the local whereabouts can be as exciting without all the CO2 emissions?

zakk··on Getting Started with Quantum Computing in Python
Simply put: slower.

A quantum computer can solve certain problems within a certain computational complexity class, which would fall in a different class on a classical computer!

Given a long enough amount of time, a classical computer can calculate everything a quantum computer can.
