This is a brilliant technique called subpixel rendering.[0] A "typical" computer screen's pixels are split into three columns of red, green and blue, instead of lighting up as a solid square. Using color fringing at non-pixel-aligned edges of characters can effectively triple the perceived horizontal resolution.

Wrong assumptions about the pixel layout will show up very badly, as shown in [1].
HiDPI displays (also mobile, not just 4K) get no real benefit from this and usually have a more complex subpixel layout anyway. I remember seeing old iPads usually showing awful fringes as subpixel rendering was enabled without considering the actual orientation of the display.

HEY LOOKIT, THIS HERE'S A SUMMARY: angry man yelling at clouds gets downvoted.

You mean a topic sentence or an introduction? You mean Bottom Line Up Front (BLUF) format?

Or do you mean that millennial minds are simply too advanced to be able to parse these kind of things without that annoying "TLDR:" tag?

So yes, I agree you should have the essence of a TLDR, but I don't agree it needs to be called that or tagged that way. I don't think that's in any way a recent or novel invention. I think to literally write "TLDR:" is rather unpleasant and gives the impression that you think the reader lazy, and he needs overly obvious pointers.

So from now on, I resolve to use "HEY LOOKIT, THIS HERE'S A SUMMARY:" instead of "TLDR:".
Hard to proof this but anecdotally lots of energy that used to go into people's hobby or passion websites now is going into digital platforms like reddit, pinterest or Twitter, or if lucky substack or Medium. Some of those are walled gardens and Reddit as discussed here is where people now search. Much less out on the actual net

So, I don’t really see how this is a huge improvement.

> “The first report of a zolpidem awakening came from South Africa, in 1999. A patient named Louis Viljoen, who, three years before, was declared vegetative after he was hit by a truck, had taken to clawing at his mattress during the night. Thinking he was suffering from insomnia, his family doctor suggested zolpidem to help him sleep. But 20 minutes after his mother ground the tablet up and fed it to him through a straw, Viljoen began to stir. His eyes, which normally wandered the room, vacant and unfocused, flickered with the light of consciousness. And then he began to talk (his first words were “Hello, Mummy”), and move (he could control his limbs and facial muscles). A few hours later he became unresponsive. But the next day, and for many days after that, zolpidem revived him, a few hours at a time” - https://www.nytimes.com/2011/12/04/magazine/can-ambien-wake-...

The 90s were like that. Tech was a much smaller community and you could cold email just about anyone with a decent probability of a response because being on the Internet was a highly selective filter in its own right. In its own way, it was a golden age in terms of accessibility to really smart people.

It was a brilliant moment in time. I was able to routinely chat with an astonishing number of excellent and famous minds when I was young and impressionable in a way that would never happen today. I feel very fortunate to have lived that, it had an enormous impact on my life I think. And it was safe for the people I corresponded with to be accessible back then.

For starters, there's the Unicode Technical Report (UTR) #36 [0], "Unicode Security Considerations". It covers this particular issue in section 2.5 [1].

The general answer is to not allow (e.g., ignore it, remove it, but do not render it) in any identifiers, filenames, domainname labels, usernames, and other security-sensitive strings, U+202E between characters of scripts that are not bi-directional and which flow in the same direction. More generally, do not allow mixing of scripts in certain contexts -- for example, do not allow mixed scripts in a single domainname label. Some of these rules need to be implemented by, e.g., DNS registries, and may need to be tailored to their specific needs (e.g., you might find that .kr has to allow mixing of ASCII letters and Hangul characters because it's common in South Korea to add "ing" to names to make brands out of them).

UTR #36 doesn't go far enough, in my opinion.

Yeah, but you can get zip ties that are uniquely numbered and colored. They’re meant to help ensure that cargo shipments get to their destination without being tampered with, which is exactly the kind of threat model we need to use against the TSA.

Yes, those could be faked. But your regular joe TSA agent isn’t going to be able to do that, just like your regular 18 wheeler driver isn’t going to be able to do that.

If you’re dealing with someone that wants to break into your luggage and they can fake the uniquely numbered and colored zip ties, then you’ve got a much higher threat on your hands that you need to deal with in other ways.

In business reports, it's called an "Executive Summary" and for academic papers "Abstract".

I find that the web page layout gives hints as to whether it is just eyeballs harvesting. Ads in the margins and interspersed with the content: probably a good idea to fast forward to the end.

Show HN: Open-core icon sets that took me 12 years to create
Hi HN,

Vincent here, maker of Streamline 4.0. I spent the past 12 years perfecting icons and making the largest sets on the internet.

The 5 open-source sets are:

1. User Interface Icon Set (1,000 icons)

2. Streamline Flex (500 icons)

3. Streamline Flat (500 icons)

4. Covid Icons (147 icons)

5. Nasty Icons (45 icons)

The specific example may be faulty but the general point absolutely is not. I've built turn based games where enumerating the space of actions grew at a x b x c and would have easily measured in the megabytes.

It's just not a practical general solution, but it sure works fine for something like Monopoly.
Hmm, I think for now it's relatively easily distinguishable. I've noticed that HN'ers feel "like me". So I look for that specific signal. I look for signals that care about curiosity and an insane hunger for the truth. Also, it's tough to mimic "Oh yea, I was at Xerox Parc programming this language that was posted about, let me give some nuanced insights into what was stated in the article" (that quote was made up for the sake of example).

The only marketeer that would be able to consistently fool me might be a marketeer that was a developer. But last time I applied for a junior marketeer position I was asked: given your resume, don't you want to be a developer instead? So devs seem to get pidgeonholed into always being devs.
I was thinking of an air conditioner - a perfect A/C would mean the temperature is flat. Although hmm, I think R^2 is undefined rather than 0 there.

I really not have the need to do that. Perhaps on a few weird sites. But it's far from being the usual thing to see a video on a browser.
> the concept of "experienced time" is not well defined for photons.

how is that different from 'photons don't have experienced time'
There are certainly things that can be done. UTR #36 covers some of the things that can be done.

Besides refusing to render U+202E when it is between characters of scripts that aren't bi-directional and flow in the same direction, the UI could display the string in ways that make it clear (e.g., different color, maybe add a warning tooltip, maybe add a dialog around an operation that could be dangerous, or maybe refuse to perform dangerous operations).
re: BLUF

In newspaper journalism the principle used to be to write the essential information first and then go into additional details the further you got into the article. When space was running tight, editors would simple chop off the bottom of articles to make them fit without needing to rewrite anything.
Not sure your point here. The submission title is based on the interest of someone that is well known for writing from a conservative point of view but changed his established view point based on other factors. It was not clear to me if most people would known who he was. The title was picked in order to provoke interest in a person that had a great deal of influence on a generation. The first comment proves that. The title 100% reflects the content of the story linked.

Do you think that people that have given their DNA for a rape-kit or some other reason would think twice about later committing a property crime, knowing that info was put into a database that could be used against them indefinitely?

The point is that a) when you voluntarily give information, you've given it - and can have no reasonable expectation that the cat can be put back into the bag. and b) it's wrong to worry about a guilty person being caught because the truth was just too darn easy to find. Justice is a search for truth. Liberty is in a way the choice of what to share, but it doesn't matter why you shared - you did, it's out.
My new desktop build was assembled from components purchased from B&H, Amazon and BestBuy. My preference was to use B&H where possible, but had to turn to BestBuy to get a retail new GPU. At Amazon I will only buy products that are Ships from/Sold by Amazon.com. I do not live near a Microcenter so can't make much use of them.

For some other stuff I turn to the manufacturer directly, like I will typically buy Microsoft equipment directly from Microsoft. I also check Costco, but they have exceptionally limited options.

Walking into my local PC repair shop, I found knowledgeable staff but prices that couldn't compete with B&H.
> My reading of your parent comment was that "no software or hardware was remotely disabled" was intended to mean, "there was nothing even a little bit like dialing hardware or software," not,"no hardware or software was disabled from a distance."

How is that a reasonable reading of their comment?

They wrote:

> No software or hardware was remotely disabled.

How can that not mean:

> "no hardware or software was disabled from a distance"

"from a distance" and "remote" are, pretty much, the same thing in the context of computer systems.

> I also don't really expect Newegg to manually verify every open box motherboard is functional before shipping it to customers

There is more to this story which strongly suggests that Newegg was told by Gigabyte that this motherboard was broken before they resold it as open box, but even if they didn't: you can't have the "don't manually verify every return before reselling it" policy AND the "refuse returns for open box purchases if they're broken" policy, yet they did.

Unicode certainly has been a source of security vulnerabilities.

Are you overreacting? Unless you were proposing we rip it out, no, you're not.

Unicode isn't going anywhere. That's because the scripts that human languages use aren't going anywhere. And people do mix scripts, too.

There are answers though. First, Unicode has been a learning experience, and we're still all learning. Second, one of the outputs of all that learning that has happened so far is UTR #36 (https://www.unicode.org/reports/tr36/), which does cover a lot of these things.

The point is just every bit of logic about when an action is enabled must be implemented on the backend for verification, so spelling that out to the client reduces duplication.

Huh, I had thought that you could use meat glue [1] to synthesize steak-like things from lower end chunks of meat pretty effectively, and sort of assumed that you could scale that up in a 3d printer type setup to achieve something resembling a steak. Is that not the case?

Here's an example of a meat glued steak being produced from small chunks:

https://www.youtube.com/watch?v=BA6TKxu8Vhk

It's obviously not as significant a reconstruction as going from even ground beef to steak, let alone cell slurry. But I guess I figured that was primarily a matter of precise printing, rather than something more complex.
