Feet and inches aren't really in "base twelve", because it's not a positional number system. For example, what's 1/3 of an inch?

I think we'd be better off using dozenal numbers, but that ship sailed a long time ago.
It's time to differentiate selling "Bob is in Location X" from "Show this ad to all people at location X".

The first case is a far far bigger privacy concern to me, and seems to be what mobile networks were doing. Facebook, Google, and Microsoft are doing the latter.
But they also scoff at things that never take over the world. So it doesn't actually mean that it's ahead of its time. It could be an overcomplicated mess that you don't actually need, and it could to be that forever.
But in these clusters where a VM is too much overhead, isn't LUKS and the others?

I manage huge compute clusters, with and without VMs, and can't imagine a feasible use case for this, barring a time machine to the 90s.
Not too sure about that. Many of the rudest people I've encountered online are retirees.
There's a lot of connections between projective geometry and geometric algebra (well-- at least exterior algebra. Not sure about 'geometric', because I don't know what the geometric product means). If you implement _oriented_ projective geometry in homogenous coordinates (so a point (x,y) is a vector (x,y,1)), then the meet and join operators are implemented as ∧ and ∨. You can make a little dictionary:

Join = ∧, Meet = ∨. Vector = point, Bivector = line, Trivector = area, etc. The figure spanned by points (a,b,c) = a ∧ b ∧ c. The boundary of the figure = ∧^(k-1) of the metric (a,b,c), equal to ∂(a,b,c) = a ∧ b + b ∧ c + c ∧ a.

I have a very amateur blog that I never publicize about this stuff and I had a long post about this, but I've taken it down for now to rework it, or I'd link it here. Suffice to say there's a lot of connections and I feel like there are even more here that haven't been discovered yet.

The book "Oriented Projective Geometry" by Stolfi has a lot of this, although it doesn't explicitly talk about geometric algebra or the wedge product -- but it uses all the same symbols. I'm on the lookout for a better reference that bridges the gap.

[I have so far not figured out what the exterior derivative means in projective geometry, besides being dual to ∂; I believe that if derivative operators are just dual to basis vectors, then d is literally just dual to ∂. Not sure. I also have no idea what the geometric product means, and tend to be skeptical of it for that meaning.]
Older software should always have fewer bugs simply due to maturity. Ie. progress isn't free. The best way to mitigate that is where distros like Debian stable come in. They help gate these developments, releasing more well tested versions of the software and fixing any critical issues that come up with it over the time of the release.
I'd much rather see easily portable desktop environments configs e.g. in KDE and xfce
For me it's more a discussion or dialogue with one speaker. The same an old theater play would act it a convicted character - s/he will say one position/argument, then the other. There's no description of the bagel (so it's not as if images are replaced by a voice), but there might be (not always) a discussion what to do with it in my head, where I'm trying to formulate my want/choice. So it's the facets of the thinking procesd that might be played out. It's also not always a discussion, it could eg be a commentary or critique (both positive and negative) of what I'm doing. ("One more pushup, come on."; "I think I had too much tea already": "will she notice I've gone to the bathroom three times in the last hour?" ...) Other days or eg when I'm busy/in the flow there might be much less dialogue.
I also used this to learn Dvorak, back in 2016.
A couple of days ago I posted a link to the BLASTN sequence alignment between the 2003 SARS virus and the Wuhan virus in a comment on one of the other discussions here.

You can see they are closely related, at about 88% sequence identity. There are point mutations spread more or less evenly over the entire genome. This is how evolution works on genomes, and basically rules out genetic engineering, since researchers would perform specific localized changes to specific proteins, or contiguous insertions of genetic material from evolutionarily distant sources.

Source: Go over to NCBI and do the alignment yourself, also am PhD biologist.

PS: The amount of pseudoscience being peddled for attention or thrills in these threads is getting really worrying to me, I had expected something totally different from this community. :/
OK... Your point is that there exist comments that could follow from the racist premise "all Indians are bad people", but are also justifiable by non-racist premises like "most scammers are Indian"? Thanks for explaining logic, I guess.

We are actually seeing it gradually, but not as the smaller-cleaner language. Rather, as cleaner idioms channeling the spirit of that language - within an ever-widening C++.

The boiling point of water may not be useful on a day-to-day basis, but the freezing point certainly is. 0C is a lot less arbitrary than 32F. Other temperature mileposts are just a matter of getting used to them; 100F is pretty hot, as is 35C.

> I'm not making an argument for cancel culture, which has flaws of its own. When I talk about extremists I have narrow and specific criteria for inclusion in that category, most importantly the advocacy of genocide.

No one would disagree with that definition. Your comment's parent made the point that exclusionary language is used in many in-groups, not just bigoted ones.

Your contribution was to say that the parent is talking about left-leaning people like they are - in your words - genocide advocates. I don't know that this is a quality contribution.

> You seem to be assuming that most people are mindless, and further that I'm talking about the broad mass of people.

Are you saying that people generally have control over their opinions and predispositions? I know I can't change my views at will, Lord knows if I could I'd become a bit more woke to fit in better.
Sometimes C++'s evolution reminds me of the quote from Antoine de Saint-Exupery: "Perfection is achieved, not when there is nothing more to add, but when there is nothing left to take away." [0]

When the topic of C++'s huge and growing complexity comes up, opinions mostly fall into two groups: (a) the language is way way too complex, and (b) ... yeah, but modern C++ is really clean and you can just ignore all the complexity that's been retained for backwards compatibility.

I don't find (b) persuasive because every line of C++ code is interpreted by the entire language standard. If (b) really is true, then I'd be interested in seeing a new language that has only the subset of the C++ standard considered "modern". If that language was actually useful, I'd eagerly use it in practice.

Great and informative article unlike my comment
For business we want something that works. At my last three jobs in a row I've had problems that systemd has been solving in an elegant, robust way. (Eight years ago it was startup ordering bugs with Upstart in an appliance; four years ago it was cleaning up a pile of cronjobs and handling the ordering relationships between them; today it's cleaning up a single cronjob that starts a big supervisord.)

For home use, sure, there's a joy to making things work. Same as some people enjoy building a computer from parts - but you'll never see a business telling their employees to go to PCPartPicker and put something together.
Facebook, google, anything tied to your bank accounts, anything you access with your phone or from your home address, if any of those things you access use your email, anything tied to your email - which ends up being just about everything. Even if I might not know your name, there are probably a dozen big data companies that can tie your name to 99% of your web activity.

Even where there's some anonymity by using a user name, there's rarely anonymity from legal authorities, who can easily access your entire internet and location history - and a VPN won't help you, because those aren't secure.
I think it means deeply flawed as in, reinvent security instead of using battle tested methods.
I've definitely seen at least some people more entertained by intrigue, drama, getting away with all sorts of crime, even sometimes getting caugh, and generally being tempted by "evil", than leading a virtuous life.

Motives are surely many and varied. For some it's as simple as saving face and a job, others are way more driven to turned a blind eye, help, or mastermind the bad.

Where does it begin? Well, some schools of developmental psychology claim that even the time spent in the womb predisposes us to certain adult-life outcomes.

I'm not remotely a cryptographer. And I'm not saying there is anything wrong with his algos obviously.
But I remember when the algos designed by Bruce Schneier were all the rage, and I think it was similarly based on some sort of guru status.
If I look at Bernstein's most cited papers, they are all about performance, aside from what appears to be a survey on post-quantum crypto and what does seem to be like a well-cited paper on AES cache timing attacks.

So my genuine question is: does he really have an unusual academic standing as a cryptographer?

This ranking by citation (which appears to be up-to-date/live) puts him in position 62:
https://kodu.ut.ee/~lipmaa/cites/cites.php?data=crypto

Granted, it's just a ranking by citation, and this definitely puts him in the top 100, which is nothing to scoff at, but I'm still wondering if there is a similar effect, and if in ten years we won't be using algos all written by some other guy because he's the new cool kid.
I write C++ for video games, and garbage collection is often shunned in performance-critical systems since it's often nondeterministic and GC pauses can become too long. I think garbage collection could work in games, but it's commonly implemented for use cases that are not video games (eg: servers, desktop applications, etc.)

A programmer writing managed C# in an engine like Unity will often spend a lot of programming time ensuring that the code will not allocate every frame, as the additions to the heap will eventually trigger a pause.

That said, every game and its requirements are different, and some game development might not mind that as much. A C++ engine programmer on a Nintendo Switch is in a very different situation than a hobbyist in JavaScript or a server backend programmer on a mobile game.

When coding, I have a mix of imagery with monologue. Kind of like watching a very technical documentary with a narrator explaining what is happening on the screen.

I also tend to remember a lot of facts after I watch documentaries, sometimes I can recall facts from a documentary many years later. It's similar to how my mind works so it's easy for me to digest.

I can visualize a very complex concept but I need my inner voice to dumb it down so that I can make an actionable decision. Sometimes I talk myself through the same visual concept in different ways to make sense of it from many angles.

I can imagine what it's like to visualize concepts with only abstract imagery, but I feel that in order to actually make decisions, a person needs some kind of mental mechanism to dumb it down. For me, the internal monologue is the best way to dumb down complex concepts and actually make decisions.

Decision-making for me is all about dumbing down very complex inputs and producing a single yes/no output.

Occam's razor says no. The coronavirus spike protein is responsible for receptor binding and entry into the cell. Different strains with different hosts bind to different receptors, so they have differences in their spike protein sequences. Mutations in the spike protein are expected in the evolution of coronavirus.

2 weeks is probably not enough, right? Assuming that it would be feasible for everyone to stay home for 100% of the time, that would still leave everyone in contact with N (avg number of people per household) minus 1 people, so for the isolation period to be able to eradicate a disease, in the worst case of each of those N people getting infected one after another instead of in parallel or all at the same time, that period would need to last for (N - 1) * (incubation time + period of possible infection), or something along those lines.

Yep, I wanted to create a systemd timer to run my nightly backups.

BeefLang will report leaks as they occur, not when the program shuts down. There's a tracing "GC" in debug mode for detecting unreachable memory in realtime. It's also used for reliably detecting use-after-free since memory is held when there are references and released when the last reference goes away -- again, a debug-only feature.

Well, modern Android devices for one - they support multiple users, including quest accounts. So I guess they could use this instead of their (likely horrendous as it's Android) implementation.

Still, the main aim of this is in my opinion not safe isolation of users on a single machine, but rather safe locking of the encrypted root folder.

With a normal LUKS setup, everything is inside a LUKS container, including the rootfs from which the OS itself is running. This complicates locking the LUKS container when the device gets suspended, as there will be open files, etc.

With Homed as far as I can tell, this is explicitly possible, it should be able to drop the encryption keys when machine goes to suspend, making it less likely your data will be recovered if the machine gets lost or stolen. With the keys in RAM an attacker might attempt to pull it from the machine & read the keys or use some method to defeat the lockscreen. With the keys dumped from RAM, this is no longer possible.
If the argument is that he already has enough money to retire, wouldn't his continuing to work at Google also be considered "playing around"? Most people probably wouldn't look at it that way, they'd consider him "productive" or "motivated". So why does it matter if he is working at Google or on solo pursuits?

The argument would probably be that he's lucky to be in the position he's in. But presumably he earned the money he has from working at Google. So either dismiss his entire situation by saying that anything he tries to achieve from now on is just "playing around" because he already has enough money, or respect him for trying to continue to improve his life (even if it's from a good place to start).
That's because we don't use the Imperial system. The system we use is called "US Customary".
In theory, yes.

But I don't see Microsoft or Stripe going anywhere soon. They've built many great products and delivered a lot of value to users and displacing them will not be easy.
