It was a good decision to invent tcltest rather than, say, "testtcl". Or, better yet, do not say the latter, at least in English.

Oh, I missed that. I guess it's alright then. I thought they chose this particular example to "showcase" Tcl by comparison.

I don’t consider email to be a legal form of communication.

The flipside of requiring a provider to submit paperwork to terminate your service, is the situation where in order to setup a new server with DO you'd have to file paperwork yourself. Can you imagine sending a paper letter every time you need to spin up a VM?

Which one do you prefer? paperwork in both directions or no paperwork?

How do you deal with customers that don't reply to email notifications and don't have a phone number on file?

I can appreciate how terrible must have been to suddenly find all your servers shut down, and I understand how easy it is to set up billing and forget, especially with the day to day stress of running a startup, but what would you have done if you were DO?

our site was offline because of DO.

Or maybe it's because of the bank that expired your credit card?

the first 90% takes 10% of the time, the last 10% takes 90%.

Is the second part of that statement necessary?

google translate gives a different translation: data shredder or data destructor

This is really cool! Could you please add a keyboard shortcut for focusing the input field? (perhaps a forward slash '/' like on Youtube or Github)

Sometimes I know that a precise word for what I want to say exists, and I'll know it when I see it, but I can't quite remember it in the moment. In those cases I search thesaurus for synonyms to related words; or maybe ask ChatGPT these days.

FIY, you can write `data4.all?(Integer)` because `all?` can take a pattern instead of a block, and it uses the === (just like case...when)

I just learned this myself from another comment in this thread.

UPD: why do you write `obj.<=(16)` instead of `obj <= 16`? is this a performance thing or a matter of style or something else?

That's likely because the pattern matching usage was a late addition to the article (wasn't planned from the start)

Wait what

Ruby's triple equals (`===`) is defined differently based on the type of the operand on the left hand side.

`a === b` is syntactic sugar for `a.===(b)`; and for classes `klass.===(other)` is defined as `other.is_a?(klass)`.

More examples here: https://dev.to/baweaver/understanding-ruby-triple-equals-2p9...

but without an attached probability there isn't much to learn.

But there is an attached probability implicitly. I can make some common sense assumptions about the number of people that have ever done LSD and get a lower bound on the risk (with a huge confidence interval, but still). Of course a chance of say 1 in ten millions is really small, but if the perceived benefits of doing LSD are also small, then that might be enough for me to make up my mind.

Frankly, some of the symptoms the author experienced are typical of HPPD, and some are not. Correlation isn't causation, and one datapoint absolutely does not show so much as correlation.

This is a good point, I have to decide for myself whether that person is trustworthy or not, and whether their experience is relevant to my case. But if I decide that I can trust their evidence, then I'm going to factor it into my decision, even if it's only one datapoint. If in the future a controlled study on the risks of doing LSD gets published, I can reevaluate my position then.

You almost certainly partake in activities with a chance to go far more wrong every day! In fact, if the mere possibility of something going wrong is enough to dissuade you, then you shouldn't have needed the article in the first place- there's always a chance things could go horribly wrong!

Yes, I partake in many activities that have a nonzero chance of harming me temporarily or permanently. But with each of those activities, I've decided that the potential benefits outweigh the risks. And mind you, I did not need to read extensive studies with attached probabilities do decide that crossing the road or swimming in the sea is worth the risks.

This touches on another disagreement I have with your original response. We don't live our lives constantly evaluating the risks based on peer reviewed studies with attached probabilities. We rely on common sense and our lived experiences as well as other people's experience that we learn about. The plural of anecdote is not data, but together with a healthy dose of common sense, it can provide acceptable heuristics for evaluating risks and making decisions.

hallucinogens sometimes cause minor hallucinations indefinitely

The author definitely did not think those were minor side-effects.

What's missing, crucially, is the only useful information- how many of each there are. There is nothing else that is relevant!

the evidence that a bad trip can potentially cause permanent damage is useful and relevant.

If "some guy had a bad time" was a robust argument for "never ever do this thing", it would be a bad idea to do anything ever.

"some guy got permanently fucked up doing something" is a strong argument for me to very carefully consider the potential benefits of "doing something" and whether they are worth it; in the case of LSD, for me personally, the benefits don't outweigh the potential downsides, and anecdata is more than enough for me to make this decision.

How can you trust that whatever the expression used in Finnish to denote "Artificial Intelligence" uses "wit" when translated back into English? Words in one language often don't have an exact counterpart in another language, and I'd be especially wary when it comes to languages from different families: Finnish is notorious for being one of the few European languages not part of the Indo-European family.

It may very well turn out to be the right translation, with the appropriate connotations; but without some clarification and confirmation from a native speaker, I would not trust it.

Do they have an extensive test suite? I would imagine that it's quite easy to introduce subtle bugs when porting tricky algorithms and other sciency software.

What happened on jun 14? (the dramatic drop in memory usage)

Edit: I guess this (https://github.com/ruby/ruby/pull/5944) PR was merged.

But why would a compiler engineer that's not familiar with Ruby work on Ruby? They have so many other languages to choose from. I don't necessarily think that writing a JIT in Ruby is a good strategy to attract people to work on it, but if you are going to attract compiler people, you most likely want those who are also Rubyists.

Have you mastered 9 finger touch-typing?

Really fun game, congrats! And good job sticking to it for so long, and getting it out there!

I'm curious whether you wrote an automatic solver to find the optimal number of moves per level? And does the number of moves in an optimal solution correlate with difficulty? Or are there easy levels with long optimal solutions?

Yes, about 50 square meters of leaf surface per human to offset their CO2 output. https://space.stackexchange.com/questions/26668/how-many-pla...

I think you may be confounding different kinds of understanding. There's a big difference between understanding what a statement is saying, versus understanding why a statement must hold true. And understanding why a statement holds doesn't necessarily have to be a formal proof, it just means that you have convinced yourself that some concepts that you are familiar with behave in a way to support the statement. It can actually happen that following a correct formal proof doesn't automatically help you understand why something is true. And vice-versa, it may happen that when you try to formalize your understanding, you discover that you missed some crucial details.

But usually true understanding and formal proofs go hand in hand.

P.S: Though as a disclaimer, I don't know maths beyond the undergraduate level, and I'm sure there must be very complicated concepts that mathematicians don't understand, but can reason formally about, as well as concepts that mathematicians feel that they intuitively understand but can't quite prove.

Additionaly, there's von Neuman saying "Young man, in mathematics you don't understand things. You just get used to them"

Does the desired behavior continue after the initial 28 day period? One problem I encountered when I tried to change my behavior using similar methods is that I don't know how strict I should be with myself. For example if I don't want to quit playing games entirely, and I'd like to enjoy the occasional game, I might set some soft limits, but that opens the door for a relapse in the future.

Or do you find that even temporary abstinence is worthwhile, even if the bad behavior comes back after some time?

It seems like you've worked out a system. How many addictions/unwanted behaviors did you manage to eradicate this way?

I did the same thing, I put my phone in Grayscale mode. It seems to help. It's incredible how much more enticing the colored versions of the thumbnails for shorts and videos are. The Grayscale also works as a reminder that I need to pay attention to my Youtube consumption.

However I imagine that I'll have to find a way to temporarily disable Grayscale for taking pictures and some other tasks.

Regarding the shorts, I really wish there were a setting to disable them altogether. They are pure evil.

Hey, that's really awesome. It's really nice to hear that you're making a difference! Good luck with the project!

Maybe host a math contest forum for working adults where we can work on interesting integrals & suchlike :)

I'm sure you must know about https://artofproblemsolving.com/community They have a huge collection of problems, and sometimes solutions.

I'm somewhat curious about the logistics of the courses. How many students are in your classes? Do you run one-on-ones online? And are they really one-on-one, i.e. only one student at a time? Or is it more like office-hours?

Also how much time does it take you weekly to prepare the course materials and to check the homeworks?

if everyone else will employ the same "unconventional ways" to search for jobs, these whoshiring threads will become useless. Let's all follow the rules.

Here tmpburning: https://news.ycombinator.com/item?id=26662154 @dang says ASCII art is strongly discouraged, as it leads to an arms race that makes the whole thread hard to read.

I assume posting self-promotional comments that are off-topic is even more against the spirit of this thread.

Are you suggesting that Tate was crossing the land border out of Romania clandestinely?

I guess I need to read up on him, I thought he was a grifter and a confidence man, getting rich of his social media influence. I thought all his criminal activity was limited to white-collar crime.

UPD: > ...Schengen... I don't think it's particularly tightly controlled.

I don't think that's right. I bet it's incredibly well controlled. That's pretty much the gateway to all other Schengen countries. There are very limited border controls within the Schengen Area, so I imagine the outer borders have to be secure.
