Someone I know did something similar, was arrested in their college dorm, and at the sentencing hearing in federal court was fined and sentenced to 5 years probation, and now has a criminal record.

This kid is very very lucky. Obviously they violated the CFAA which carries severe criminal penalties. They engaged in actual hacking without any permission or defined scope. And they exploited the system without any responsible disclosure process.

Anyone in the field will tell you that this is an absolute disaster of a post because it sends the signal to other young aspiring cybersecurity professionals that this is OK, and the school will laugh it off, and you'll be seen as an adorable Matthew Broderick type Wargames character. I can't overemphasize how far this is from the truth in 2021.

Absolutely do not access systems you are not allowed to. If you do want to do penetration testing, you need permission from the systems owner and a clearly defined scope. And when you do find issues, you don't exploit them, you responsibly disclose them within a clearly defined framework.

If you want to end up with a criminal record that will profoundly effect the rest of your life, including your career prospects and ability to travel internationally, then by all means, do what this guy did.

I wish it wasn't so. It never used to be. But this is how it is now. Overzealous prosecutors have been given a huge amount of power, and all you need is one embarrassed systems administrator, school board or management team to trigger a disastrous outcome in stories like this.
That's because natural data has low entropy

But let's say every paragraph only offers 1 bit of entropy. Then a 160 bit hash gives you fuzzy accuracy up to 160 paragraphs. After that you'll have to extend the hash with hints to guide which sequence of paragraphs you're looking for, & hints for where the typos are

ofc, 100x compression of English text doesn't require this amount of compute to decompress: https://en.wikipedia.org/wiki/Hutter_Prize

It's also impractical since most compression use cases want to put the work in compression, & have decompression be straight forward

edit: 100x was misreading, it's currently 8.6x http://prize.hutter1.net/#prev
Find people that are skeptical about the benefits of blockchains/cryptocurrencies AND have a strong technical understand is so rare. This is not one of them.

So far the best person that has that intersection I have found is Angela Walsh.
> The court of appeals ruled: “The saline solution acquires heat from the retailer’s cellar; therefore, energy belonging to the brewery is not being stolen. On the contrary, the brewery is receiving gratuitous energy from the retailer.”

Of course, there are cases where sending gratuitous energy to your neighbor clearly appears to be tortious. Like a high-powered laser weapon.
No, you entered it fine, but our software has recently begun rewriting URLs to the canonical URL if the page has one, and this page has

//actu.epfl.ch/news/scientists-discover-a-highly-potent-antibody-again/

...which isn't valid, but we might as well tweak the code to handle such cases. In the meantime I've restored the URL. Sorry for the error!
Why not just pay a scalper off stock or eBay at that point? Do you really care who pockets the difference?
A 30min walk would get me to two convenience stores and a doughnut shop. It would take me about 1hr to walk (briskly) to the nearest grocery store.

And I live in a city where the zoning can be described as "we'll rubber stamp literally anything that isn't hazmat processing we're desperate for money". And this is a ~150yo neighrborhood in a multi-hundred year old city in the northeast, not some socal dump that was built out long after the advent of cars.
That doesn’t seem to match. In this case, AFAICT, both wanted the cooling effect. No one wants the heat.

The saline solution was now being used to cool double the volume (2x the cellar space), so it seems pretty clear-cut to me — if saline cooling cost increases with volume being cooled, it should be trivial to say he’s now covering someone else’s costs. I don’t even see why we even need to bother digging into thermodynamics — looking at the cost structure of the cooling unit alone should tell us the answer. If there’s no relationship saline-usage-cost based on volume, then it still taken but no harm was done. If there is, then it’s trivial to calculate how much harm occurred

If one cellar was being heated, and the other cooled, then your paradox could be triggered (but it also seems to me the “paradox” is trivially resolved by double-entry accounting — the problem is simply in the name “waste”)
This wasn't making sense to me, then I got to the meat:

> The real risk is that blockchain Twitter will begin to censor dubiously defined “hate speech”, or that blockchain Mastercard will add support for chargebacks.

This is just culture warism. In fact moderated discussion forums[1] and reversible payments are DESIRED FEATURES of products in the real world. Of course that's going to happen. But to the author that constitutes "centralization", but what it really means is "not the libertarian utopia I imagined".

I am going to copy this in my code. Great post.

Since I do Java code, my guess is to use Spring AOP and create an aspect for this that has a point-cut on an annotation called something like @EmailOnError.
Errr... I never said anything at all was wrong with MCAS.
as the article points to by namedropping Shirky, this is the natural result of offering choice among many diverse options, which tends to create power law distributions, the idea that the free-wheeling nature of platforms produces equal outcomes was always, based on the nature of social networks, impossible.

The Verge had a good and sobering article about what that means in practice:

I know you're being sarcastic, but please don't use the "just" word to talk about trillion dollar infrastructure projects that require product-ionizing thus-far theoretical technologies.
Seems pretty smart on their part to me. I mean unless we are all going to fight with the same resources why wouldn’t they do anything in their power? I know we have some rules of war but I highly doubt these guys agreed to such rules and why should they it would seriously put them at a disadvantage. I know nothing of these conflicts or those involved but war is ugly we should expect to see as much.
Just wondering, are they currently lying about having made these guidelines before? I haven't heard anything about that myself. I also do remember some news articles saying the government's mask guidelines were so hospitals could stock up (maybe it was once they flip flopped, I forget, it was over a year ago, but I do recall reading that).

I think it's possible they deleted old content to make sure invalid data isn't out there on the web to be cached, linked to, quoted, etc.

However, if they really are lying now (i.e. making current statements) saying that they never flip flopped, then yeah that would be weird.
That's a fair point. This isn't something that can really be legislated (at least not effectively), so you need successive administrations to be on the same page with this, which isn't likely.
Advocating for increased corporate scrutiny across the board is totally orthogonal to advocating for increased scrutiny of a particular company based on the isolated rantings of this wombat.
Well, I imagine that would require using a brain, which may an onerous requirement.
To each their own. I always enjoyed the metaphors and ambiguity, even if it meant I have to re-read a page after going "wait, WTF just happened". Reminds me of poetry analysis or classic literature class. Understandingly frustrating if you just want to charge through and find out what happens.

Gene Wolfe is also a master of this style, although he employs less metaphor, more ambiguity, and unreliable narrators.
So during the Space Shuttle (and earlier) era I believe the cost of getting payloads to LEO was $20-50k/kg. Currently with Falcon 9 it's gone down to ~$1000/kg. I imagine this will continue to get cheaper with further reuse and Starship.

But we really need to get down to <$10/kg. Thing is, that's entirely achievable. I believe the ultimate future here will be orbital rings [1]. Space elevators get a lot more attention and they really shouldn't because they're a lot less achievable and they require materials we haven't invented yet (to resist the centrifugal force).

Imagine being able to take a cable car into orbit. That's what orbital rings promise and you need little more than copper wire and stainless steel.

Not only would this bootstrap colonization of space but you can simply attach collectors to the ring itself and run the power down a cable to the ground so you don't even need to suffer the power loss from wireless transmission (which, for the record, is a practical method still).

I can tell you that when training interviewers, Amazon makes it very clear that candidate experience is the most important thing about the interview. Stoically asking questions without a wink of emotion certainly does not fit that. :(
You could just implement enough surge pricing that people/companies work around peak times on their own and build their own storage.
I think I don’t understand your types. The Effect type you define appears to be, essentially, a function that takes infinitely many arguments of type a.

Let’s imagine two simple effects. One prints a string (I’ll call this ‘printer’) and one reads an int entered by the user (let’s call it ‘reader’) In this case, how would those effects be modelled with the types you wrote?
Pretty sure there's nothing stopping the school district from retroactively recinding his graduation, or refusing to send transcripts to universities, or informing those universities of his transgressions, which would probably result in revoked admission.

I think that's exactly the point. In this context, planned obsolescence of plastics is the goal, because currently they last much longer than needed. I'm having trouble seeing how this might lead to planned obsolescence of non-plastic goods that you would want to keep around for a long while.
This post is 100% spot on. While the local school district may treat it as a prank, in the U.S. the federal authorities may not. To see how seriously the government takes this act, look at the penalties section of the relevant U.S. code.

Also, I believe the US Army wanted an interstate highway system to use in place of the rail network. So there were many stakeholders that brought us this car centric landscape into existence.
I somewhat agree, and I think it's largely already happening. For the most part I think it's unlikely anybody who's not somewhat tech savvy would ever move their coins off of a service/exchange like CoinBase, and such an exchange already provides some of those guarantees and could easily provide more. All the benefits and drawbacks of bitcoin pretty much go away if you never actually use any "physical" bitcoins and just go through an exchange. That said I have my doubts about it ever actually getting all that big for everyday use, everybody is always going to need dollars so I don't think there's all that much of a reason for big banks and payment systems to "switch".
During WWII, the bulk of the population didn't have huge, well-watered and fertilized lawns, either.
The context of HN is that of "intellectual curiosity". Serious matters require much more respect than "curiosity". The tentative approach we may use with discussing engineering and worldly trends is not appropriate with them.

Dirac was used to provide a simile to make you understand the point: you seem to be using a text outside its purpose.

Contemporary advancements in the field of logic seem more pertinent to your interest: you demonstrate a penchant for syntax, and contemporary logic was largely busy in studying complexity in a formal way. But also in philosophy: there are studies where the topic was explicitly that which seems to intrigue you - without the need to bend other texts outside their purpose.

The matter of the false dichotomy, a formal note, is completely irrelevant to the content. That «there are [no] other options» does not seem the least bit relevant to the message I wrote: was it understood? It was there for understanding. Some things are not belief systems, hence they will not be part of the consistency game in the Weltaufbau. How does mentioning that there could be more options help clarify that or correct it?

The respect which creates reticence is in that before speaking of something (some domains more than others), one must know about it, with sufficient degree. Similarly for the counterpart.

Incidentally: you wrote about «speaking with precision, accuracy, and non-ambiguity», and the broad context is about a text with starts with saying "If you can talk about it, it is not the Way". And you call it not being «easy to understand» a «shortcoming»: are you sure you understood what the text is about?!

The intention of the author was very probably religious. If you are interested in the matter, good. It will probably not take you a weekend.

If you understand promises you pretty much understand monads already since promises are more or less a type of monad.

Monads represent computation contexts. In the case of promises, the computation is preformed in the context of a value that will be available some time in the future (or not at all in some cases).

my_promise.then(compute_result)

Another context could be a list, where the computation is performed on each value in the list

my_list.then(increment)

Or the context could be that the value is maybe null

maybe_string.then(uppercase)

How the computation is actually performed depends entirely on the monad. Usually .then is called .bind or .flat_map because it will automatically unwrap nested monads.
When I was in elementary school in the early 90's, I discovered you could use AppleTalk to print to just about any printer in the district.

I would print pages and pages of "I AM THE MASS PAPER WASTER!!!" to random printers in other buildings. I'm genuinely curious if it actually worked.
Imagine this were a workplace: some kind of suspended catwalk where accidentally falling off it is fatal. It would be an OSHA violation not to have guard rails to prevent this from occurring. Likewise, if this is a road where cars are moving too quickly to stop in time to avoid fatally hitting someone who falls onto the road, there ought to be a barrier between the pavement and the road except at designated crossing points.

> you and I? We don't have it so bad.

Still talking past the point, eh? I'm doing fine. I'm concerned about the world that my children, and my grandchildren will live in. I'll be quite old, probably dead, by the time that we're projected to see the collapse of the gulf stream, blue ocean event, +4C, etc, but I'll live to meet the people who will want to survive through those events.

We nailed the Ozone Layer catastrophe. It required worldwide collaboration, but we did it. We're already seeing lethal effects of climate change, and nobody in power seems to give a fuck like they did before.

But yeah, I don't have it so bad. Never said I didn't. I'm thinking about 100-200 years down the line; you keep telling me about how great things are today.
Looks like they needed 1.5 millions GPU hours to find a collision with a random hash.
One unsolved problem with those small reactors is security. How do you prevent some terrorists from building dirty bombs with material stolen from a company's basement reactor? How do you trace the vast amount of radioactive material at so many sites?
Cold start has been a problem with Lambda since day 1, and in fact has massively improved in recent years.

Node.js is optimized for request throughput rather than startup time. The assumption is that you will have a "hot" server running indefinitely. The Lambda pattern is in general a very recent invention, and not something that languages/rutimes have specifically considered in their design yet.
Correct. It now goes by the name Adobe Animate.

Your original question of "does typescript get better?" can be rephrased as "does any tool become easier to wield with greater/better understanding?" and the answer is "yes".

Without a [concrete] example of what type of issues you faced, I doubt anyone can give you actionable advice, though.

> My JS code has no issues.

Either the types were wrong, or the code was wrong, either way there is an issue. Since you said you're inexperienced with typescript, it's possible the types were erong.

There are certain JavaScript patterns where TypeScript can be a bit inexpressive/unergonomic (especially with a lot of "metaprogramming" or "runtime polymorphism"[1] involved).

[1]: Most of the cases in our company the difficulty of expressing some types of "runtime polymorphism" was what I call thoughtless polymorphism (ie, it usually hides runtime errors that you're unaware of, especially if there's a proliferation of `anys`s in the code)
Isn't it still the case mathematically that 3 layers can do theoretically anything? Which of course may be a different claim that they can do that practically.
Thank you very much, I've been thinking about something like this for a while and have been meaning to look for a solution. Problem solved, thanks!
Not it's not. You can't distinguish the complete works of Shakespeare from the complete works of Shakespeare with the words changed a bit, or switching to Harry Potter for a bit in the middle, or a completely dazzling and original work of fiction. Any hash might generate all three of these, and essentially boundless other works. It's a library of Babel.
Git was created 16 years ago. The impending breakage of SHA-1 was known even at that time, just like how MD5 had been broken before it.

I'm honestly still shocked that updating the hashing algorithm wasn't built into Git from day one. I really wonder why. Did people think this wouldn't happen? Were they so in love with the performance of C/C++ being able to pass around 20 byte hashes on the stack without worrying about a more complicated structure (eg a collection of variable length hashes)?

It just seems like such a massive and foreseeable oversight that's going to cause pain for some time to come for really no reason at all.
It doesn't stop at the student level. Find something at the corp level with an arrogant IT dept, and you'll find yourself in uncomforatable situations as well.
Vlad the Impaler might have been overdoing things, but he did stuff that pretty much standard practice during the Middle Ages. Stalin on the other hand should totally be on that list.
Modular reactors don’t actually reduce costs in any meaningful way. Construction costs are significant, but surprisingly low percentage of overall costs. For example nuclear needs a large highly trained workforce for decades. Every individual pulling 100k * 50 years is 5 million dollars, and you need a large workforce. Arguably security guards and medical staff are unnecessary, but modular reactors don’t lower those costs.

Fuel is similarly expensive and no in practice reprocessing doesn’t really help. Shutting down for refueling is again expensive when you consider it happens 30 times over the lifetime of a nuclear power plant. Decommissioning is extremely expensive even if it can but off. Even highly subsidized insurance is yet again expensive. Overall construction costs aren’t limited to the reactor you still need radiation shielding, cooling towers or the equivalent, cooling ponds for waste, roads, offices etc.

Don’t get me wrong if someone had come up with a great modular reactor 20 years ago Nuclear might be much better off today, but we’re simply past the point where more R&D is going to help. The only possibly for change is if nighttime electricity costs ended up much higher than current daytime costs. However a lot of demand is being shifted to nighttime because costs are currently cheaper, change that equation and nighttime demand will fall dramatically.
Let’s see, JET 1998 Q total ca. 0.01, NIF 2021 Q total ca. 0.001 — seems like fusion is getting further away, rather than closer.
I was thinking the same thing! Any logging tool will help take the errors and group them or some kind of housekeeping to help vs 200 emails slamming an inbox.
Not just getting rid of the mines, but you need to do this all while being unnoticed.

Like I said, not impossible, but probably only happens in movies.

Stories of more enlightened school administrators are always welcome.

My story: the "second best high school in the state" had an AT&T 3b2. They wouldn't let me take any classes that used it because they were afraid of what I might do to it (their words). I mean, they weren't actually wrong to worry, but it din't really have anything on it.
'just follow the rules'... that's exactly how we get the blind unreasonableness we're seeing everywhere. you need to examine your assumption that masks are doing anything at all in most common situations, and then consider what's actually reasonable vs. what you've rationalized yourself into.

humility is missing in your thrust to convince others of your correctness.
Cookbooks are great and tutorials are great. I wish there were a place where I have access to thousands of exercises that help me internalize these concepts. This is where I really have trouble. In my daily work I regress to old habits with Ctrl shift f in my ide rather then something like ripgrep.
You're not wrong, but I think it might be helpful to think of this in different terms. Teenagers, with burgeoning agency, are being denied the ability to meaningfully impact their environment yet are bound to it for most of their lives.

I agree with you that explicit permission is important, but it is also something that young people are frequently and explicitly denied. I don't think the solution is condoning that sort of 'extracurricular', but I think we should recognize the problem is probably starting with the adults in the situation.
Stablecoins are indeed immature. But volatile assets don't make for good money. Have you heard of Gresham's Law? "Bad money drives out the good"- that is, people will hoard the lucrative asset (bitcoin) and actually use the boring one (stablecoins).
>That number seems wildly exaggerated... unless I'm missing something?

Both Apple and Facebook are wildly understood to be launching AR glasses with serious marketing pushes in 2022.

100 million units sold between the two of them over 2.5 years at an average price around the price of an iPhone (so $1000) plus some app sales adds up to $140BN. I guess. I agree that even there it seems high.
Is the retailer rerouting the coolant into his cellar, or just using the fact that his cellar is cold because of the
proximity of the pipe?

If the latter, I'd say there is no theft- the brewer needs to insulate his pipe to prevent thermal losses.

We do not yet have the technology to power California with non-nuclear renewable energy by 2045. Those estimates are based on expectations that we will have that technology by then, but we don't have these capabilities yet. What we do have today is nuclear energy that can achieve that goal by 2030, if we began today.
