skysight-inc/HackerNews huggingface dataset:
Just thought this would be interesting to share.

The base64 encoding in JWT's forces the QR-code to use segments in byte-mode. This will encode individual JWT characters in 8 bits of data.

The size of the characterset of a base64-encoded JWT is 65 (64-characters in base64 + '.'). Actually, in this spec, it is 66, including the `|`.

An optimal encoding would use Log2(66) amount of bits per character. Alphanumeric mode at 5.5 bits per character is too small, but encoding individual JWT chars as 2 numeric characters (at 3 1/3 bits each) results in a more optimal encoding (~20% space savings).

The mapping from the JWT char to 2 numeric coding is also quite trivial: take the ascii value of the char and subtract by 43.
```
def enc(c):
return "%02d"%(ord(c) - 43)
```

The fantastic website
https://www.nayuki.io/page/creating-a-qr-code-step-by-step

shows, for the JWT you posted, a size of 2164 bits needed to encode the data inside the QR-code at low error-correction (resulting in a version 10 QR-code).

If we run every char through the numeric encoding process, we get the following result:
```
05050881587831055845226236623132430638623324316155285662366231304279300635623114035878317957443062366230763441307935254207357960104644316347284366342526783479380635635609364427624607396547623072306643745624301130666105572923793662137557083579336635755508467454441375342526783479380635635609364227623807392747645768404468623324316956083462366231233805062730627662474561763063687735632276342522763425227633243107474531795444147430636862342522793067050322267659600836240809600512775277434458645742746677374170557139277538643643435241384109```

Longer in terms of characters, but if we run it through the QR-encoder, we get a bitstream of length 1801. Which is possible to fit in a Version 9 (err corr L) QR-code.

I thought this was pretty cool :)

A review of papers on digital humans from ICCV 2021
> You know what else uses the very same neural circuitry as used by slot machines and cocaine? Reading a boook. Talking a walk. Petting your dog. Existing.

And yet people will prefer slot machines, cocaine, and to some extent social media once they get addicted. Does that not indicate that while they use the same pathways, they do so in a much stronger way?
> Never understood it.

It’s clearly just a joke gift. I’m sure nobody is actually confused that they’ve really bought some legal right.

It’s like criticising a ‘kiss me quick’ t-shirt by asking if people realise the t-shirt actually has no legal power to compete people to kiss you. They already know. It’s a joke.

Same with NFTs. It’s clearly a bit of a game and joke - I don’t think anyone is actually being scammed by it.

I feel like people are working so hard to not see the joke.
quite a lot of forms of investing are pretty much gambling but one key distinction is that investing has a market function, it's a price discovery mechanism. Investors who lose in a market still serve a purpose. even if individual investors might incur losses at the very least there are external benefits to their behaviour for everyone else. Without active investing allocation of capital does not work. gambling taking place in purely isolated environments has no such benefit.

A hyper intelligent race of vultures might consider us sensitive eaters for avoiding carrion.
This was an insightful thread, but I think these arguments miss the "bigger picture" that NFTs carry with them. Yes the popular use case right now of expensive art and "selling a JPG" is rather silly, just like the art world always has been. What I see in the space however is a lot of opportunities to grow community-building tools - POAPs for example are rarely sold for profit (some still try to) and are a great way to encourage participation and attendance of events, with added functionality of rewarding said participation after an event for example. A lot of media coverage is on the absurd art market use cases, and though the possible profits make it a loud use case, it is just one sliver of potential of Blockchain technology. I am excited to see NFTs move beyond these cases, and I see that happening quite often.

Have you asked China this question lately?
Given my experience with government IT, none of that surprises me at all.

I'm sure offline check-in was mentioned at some point, but then promptly dismissed, likely by a product manager saying "they can just check in using pen and paper".

As for outages, even as a (paying) commercial customer, the closest you'll get to an SLA from any government agency is: "apart from scheduled maintenance and subject to unexpected outages, the service should be available 24x7"
Oh, but you just can't. MacOS's zsh can't deal with my tmux shell when I ssh in. There's all kinds of great features that allow for basically using pixel buffers in a shell if you stray away from the default terminal implementations. Getting colors to work properly is also still a pain.
Why would the attacker need to set the execute bit on the file they want to execute?

Can't they just run "tcpdump -ln -i lo -w /dev/null -W 1 -G 1 -z /lib64/ld-linux-x86-64.so.2" and then swap the tcpdump savefile with the file they want to execute? That will run "ld-linux-x86-64.so.2 ./savefile" after a few seconds which is the same thing as running "chmod +x savefile; ./savefile"

https://unix.stackexchange.com/questions/400621/what-is-lib6...

Anyway this whole discussion of "What if the admin was silly enough to think the execute bit did something?" is academic. If the attacker can run any binary that's already on the system as root, you've already lost.
Another Interesting NFT thread from today https://twitter.com/moxie/status/1448066579611234305 .
I didn't quote, first of all. And I didn't change the meaning.

The difference in will vs might is of no significance in my sentence. You just saw saw red, picked a tiny little thing to go off the rails about as an excuse not to engage.

I said: "the statistics ... that an unvaccinated person will kill you". If I had written "the statistics ... that an unvaccinated person might kill you" the meaning is exactly the same. The 'statistic' we're /both/ referring to is the statistic of spreading, someone catching, and dying. Not "might die", the actual incidence of dying. Studies wouldn't measure the incidence of "might" deaths. But you know that

So now that's cleared up: what is the chances of the unvaccinated "might" killing you? Which statistics have you seen? (I'm double vaccinated btw ;-)

It’s depressing. Very much so.
This seems like a reasonably good-faith analysis to me at first glance, and I think it merits being discussed.

I added a methodological question at the top level.
It's because the paper they are referencing is testing the use of immunosuppressive therapy to treat myocarditis. The conclusion that was reached was that it doesn't work.

Needless to say, that's not how myocarditis is treated in hospitals.

Then why have I never seen anyone talk about the cool NFT's they own and instead everyone talks about them making quick bucks on NFT's? Look at youtube search results, not a single person talks about the cool NFT's he has, just a lot of people trying to sell their NFT's for a quick buck.

https://www.youtube.com/results?search_query=nft

Compare with stamps, I see some people talk about making a quick buck on stamps but also a lot of people talking about their stamp collections. There is a huge difference here, the nft case you see 99% scum and 1% calling out the rest of them as scum, and not a single enthusiast who cares about the NFT. Stamps I see mostly enthusiasts and a few scum posts.

https://www.youtube.com/results?search_query=stamps

So until you can find me all these "enthusiast NFT collectors", I'll assume that they don't exist. They could exist in theory, but I have seen no evidence that a single NFT collector actually exists in this world.

Abstract: HTML code is delivered in a received message or browser window which causes an invisible window to be created. More precisely, the window is at a coordinate which is beyond the coordinates on the computer screen and, therefore, is not visible to the user. The invisible window executes additional HTML code or may draw it through the Internet from a remote cite. The additional HTML code may produce further, invisible windows, which may be animated, and are independent of anything which appears on the computer screen. For example, the user may be presented a window on his screen which offers a free stock ticker, in exchange for being presented with periodic commercial messages.

It's a misconception to think a miner will only locate on energy sites with continuous supply. It can still make perfect sense for a miner to locate on a site with variable demand (which by the way is basically every energy production site in the world that is by design compelled to build to accommodate peak demand). What a miner will do is then negotiate energy costs (which are 80-90% of their variable costs) with the producer who is happy to sell his excess production at any cost above 0 for all excess power untapped. All it takes is enough excess production at a (much lower) price than conventional rates for this to breakeven positively vs full operation alternatives.

As chips commoditize and energy trends towards 100% of all costs, miners will step into these situations exclusively.

As far as your claim that bitcoin is useless that's a personal judgement. My personal judgement is that reintroducing sound fixed supply censorship resistant money to the world is of enormous benefit. But that's beyond the scope here. I don't think it's constructive to make judgements about what people value and chose to expend resources towards. If you have a problem with externalities then have a debate about that. But who are we to judge if someone wants to heat their pool? If they do so through carbon emissions then consider taxing that. The sustainability of the energy production is your issue really, not the energy use.

The Press Freedom Index ranks countries media landscapes, not newspapers. Therefore, it cannot be used to allocate funding. We can use it to bring awareness to failings in public policy in particular countries.

I did not indicate a relationship between market and quality; on the contrary, I attempted to repudiate such a notion through a reductio ad absurdam.

How do we measure quality? How can we prevent those who benefit from poor quality media, once in power, from tweaking the measurements to give it to their supporters. That is my question.
Python Without the GIL in 2021
I agree with you on the "in secret" part, but where we differ is that I see that as a symptom of micromanagement by the company. It's not isolated to remote work either, there are plenty of people just sitting on social media at work until it's time to leave, and usually being overall less productive because of these forced hours.

Whether there's trust (on both sides) to effectively make progress is an entirely different issue. Remote work just makes it more explicit.
I completely agree. The article makes it seem so extreme. There's a way to do this without stealing from a company.

My “Hello World” Post
It irks me that articles like this (and the originals it is based on) claim to creating tiny ELF files when they are, in fact, just tricking a particular version of the Linux kernel into loading non-ELF binaries that claim to be valid. It's klever and all, but it's not doing what's claimed.

There are many OS kernels out there that use the ELF format for executable binaries. Many of them are not one particular Linux kernel. The fact that there is a series of articles based on the changing Linux kernel no longer accepting the old "tiny ELF" files is important.

I'll give kudos to the authors of these articles because they're doing something clever and fun. I just feel the urge to clarify to the internet that they're poking at exploits in a Linux kernel loader by offering it non-standard binary files and not creating tiny ELF files at all.

WTF? Timestamp is not a user-facing value, so it doesn't need to have user time zone. Timestamps are always in UTC.
I mean people literally buy "property" and space ships in virtual game worlds. NFT are no different, it's microtransactions but for rich people.

Is it a scam? well it depends whether the elite values NFT or not... it certainly is a speculative "asset" by nature.

It's not a scam provided people know what they are exactly buying. It's more of yet another "get rich quick" scheme for some.

However, beyond the speculative aspect of NFT, artists need to know that putting their art in a virtual gallery as NFT WILL COST THEM money, so the business model for the middle man is to make artist believe that they will make money from NFT. The house always wins...
Isn’t that a type of a database? And is it yours?

Certainly. As I said, it seems like a false dichotomy perhaps dictated by cost, and Android manufacturers are also guilty of this in transitioning to fingerprints only (in-display or otherwise) on many newer models.
If you’re buying NFTs with hopes of profiting from them, i.e. as assets, you’re an idiot. If you’re buying because it’s silly, funny or otherwise makes you happy, go for it. No scam there.

If you’re playing middleman, frankly, I think you’re wasting your life, but then I don’t see how you’re so different from an art dealer or auction house. At any rate, you’re probably a better allocator of those dollars than whoever gave them to you. (Exception: if you’re pitching NFTs as investments to unsophisticated investors, you deserve to be prosecuted.)

All that said, NFTs do something similar to what much of fine art and religious prohibitions do: demonstrate group membership by submitting to arbitrary prohibition and sacrifice requirements [1] with the aim of accessing club goods [2], e.g. in-group access and standing. When someone calls NFTs a scam, they’re saying those club goods are worthless. Objectively, as a crypto sceptic, the wealth made by crypto insiders would appear to reject that hypothesis. (Whether buying an NFT or expensive painting alone confers those club goods is a separate question.)

The history of cryptocurrency is exclusively people trying to come up with ideas for this extremely interesting class of data structures, yet consistently only reaching variants of "fraud." (And, those people who just jump immediately to fraud without much thinking.)
The shift is about prioritizing your time and freedom, not overworking yourself on an endless tasklist that ultimately doesn't matter.

I don't agree with the lying but it happens all the time, remote and in-office, as a symptom of clock-watching micromanagement by employers. That needs to go, and employees switching from actually putting in those long unproductive hours to quitting for better conditions is a positive move.

The paper suggests it may be myocarditis and doesn't do anything to establish normal myocarditis fluctuations in young males who are always more susceptible than females. Just looking at the influenza chart, 2018 is probably also an abnormal year compared to 2019 if influenza related myocarditis kills young males.
Even better if you combined it with an upside down screenshot of the desktop. So it looked like only the mouse was upside down and all buttons didn't work.
I am not happy with this move. Before this step the Remarkable was an easy recommendation, but syncing a few gigabytes of files for every customer that paid you $600 dollars without an extra subscription seems reasonable. Hell, have me pay for the S3 storage I’m using, anything. But to start paying $8 per month just to access basic functionality feels silly to me.

I love the device, but recommending it without the grandfathered benefits feels like a ripoff to me (even if I never use them).
You made a straight up declaration about proof of work in a pretty condescending and unsubstantiated way. I literally applied your exact framing and wording to present that approach from my point of view, and you hated that version of exactly your text. I could reply it proves the exact same point about you. I think either of those versions are not helpful to anyone, which is what I was trying to illustrate.
If NFTs are just a joke, then there's a surprisingly large number of people who are playing along. Like, far more than I could believe could actually keep a joke like this going with a straight face.
From what I've been reading in quite a lot of comments, people are indeed confused that an NFT is or can be some kind of legal ownership title. If people thought it was a joke, you wouldn't see so many people thinking that it's going to revolutionize X (whatever X is, apparently everything can be disrupted with NFTs).
