I use VB6 all the time. Need to quickly get some custom serial port thingy written? VB6. Want to make a quick window that hosts 4 embedded VLC COM instances to watch RTSP camera streams? VB6. My craziest use case out in the field was: Wall mounting a spare mouse and soldering two wires to the left button inside, running a wire back to the office with the computer playing pandora and then writing a quick app to turn down the wave out and un mute Mic In so the restaurant owner make announcements over the loudspeakers. The code was already out there for the mixer, I just had to add a line for monitoring the parallel port and adjust the sliders in someone elses code.
if you normally stay home and go out only for shopping or an occasional walk in nature then you will be safer at home. also depends if your home is rural vs urban. also it would depend on how active / social you are when at home compared to what you plan during a trip.

you have the additional risks of airports, or buses during travel. there is also the risk of being flagged down for testing. if you're positive then a forced quarantine in a foreign country sounds much worse than at home (where you speak the language). to me this would be more annoying and frightening than the virus itself.

on the upside you can probably get really good deals and empty restaurants / bars and other sites usually crowded with people. if I wouldn't live so close with family and kids (which I'd be returning to - AND be 20 years younger), I'd go.
If you're in the market for a Bootstrap Treeview you're likely already using Bootstrap and therefore jQuery.

Since the author, russjones, seems to be here, I'd like to ask a question regarding writing the actual BPF programs. I've been writing a term paper about BPF verification, the in-kernel verifier and research like PREVAIL [1], so I'm curious.

Is writing valid BPF programs really that "hard"? E.g., does one often have to rewrite programs bc. the verifier wouldn't accept them?
Do you see a need to extend BPF with more capabilities? (bounded loops have been added in Kernel 5.3, but maybe something else)

Thank you.

I think VB is still a fine compiled language and you can find a lot of use cases. On the other hand, VBA is used mostly by people who have to maintain old Office applications and basically live in MS Office. VBA is still the first choice to automate MS Office.

That's the reason I want to stay away from MS Office lol.

tmux offers a level of abstraction that's missing from a tiling WM alone.

You can have 1 tmux server running locally with many sessions (let's say 1 session per project).

Then each session can have many windows (separate terminals that are full screen).

And then each window can have many panes (splitting that window however you see fit).

But if you went with a tiling WM alone without tmux, the WM's workspaces become sessions and your terminal becomes a window. So now you're stuck having to lean on your terminal emulator for tabs and splitting windows, but you're also on the hook for it having buffer searching, copying URLs, scrolling and other things. Most terminals are really bad at those tasks but tmux is great with them when combined with something like xterm (a low input latency terminal).

Plus with tmux you have the option to easily save and restore everything with tmux-resurrect, and you can take your whole set up and replicate it on Linux, MacOS and even Windows with WSL and it all works the same as long as you find a good light weight terminal on each platform.

I think there's a lot of value in using both a tiling WM and tmux together. tmux basically super charges any terminal into having world class support for everything a terminal needs to do. Even if it didn't persist sessions, it would still be really valuable. IMO it's severely underrated. People's eyes widen and still get impressed when terminal emulators add basic tab support. If they only knew what was lurking around the corner with tmux!

Just to clarify:

> TeX is used because it's a convenient interface between higher level descriptions…

I think you mean LaTeX, not TeX. (LaTeX is a macro layer on top of TeX that provides these convenient interfaces, while TeX is a low-level typesetter.)

> Additionally, TeX is used rarely by humans…

This sounds a bit contradictory with the previous statement, but maybe you mean that TeX is rarely used directly by many people (without LaTeX or some other macro layer). In any case, the LaTeX macros are implemented in TeX, so the TeX program is always the one being used (which I think was the point of the poster you're replying to).

> And how many TeX and LaTeX reimplementation a are there?

I didn't understand the meaning or point of this, as the answer is either "very few" or "many" depending on what you're counting. Extensions of the TeX program include eTeX, pdfTeX, XeTeX and LuaTeX, not to mention a few others like pTeX and upTeX. (Confusingly, when we say “TeX” we often mean one of these programs as well, as a lot of their code comes from TeX—they are written/implemented as patches (changefiles).) Reimplementations of a small part of the TeX/LaTeX syntax for mathematical expressions (only) include MathJax and KaTeX. Are these a lot, or hardly any (would have expected a lot more)? Depends on your perspective I guess.

How’s that working for ya?

Democracies where the people only have a voice every few years are regularly seen doing things against the will of the people, because the politicians know they can get away with it, because it’ll be forgotten by the time the next election comes around.
Those are precisely the objections I'd raised with the Damien Rhiel (submitted via email, no response).

Additionally there's the problem of releasing the works to the public domain. As discussed a couple of weeks ago when the 2016 billion-dollar infringement lawsuit against Getty Images was attempted ... and thrown out of court ... the act of putting works in the public domain also extinguishes, in the court's eyes, the rights of the author to sue for any claims including moral claims of authorship.

See: https://news.ycombinator.com/item?id=22340325

So: clever stunt, but legally impotent, both by law and the self-neutering actions of the actors here.

Adam Neely's video (interviewing Rhiel and collaborator Noah Rubin) covers many points of copyright, though not the originality, authorship, or PD angles. (Posted elsewhere in thread, echoing here.)

Perhaps I am mis-undertanding the diagonal argument, but it doesn't appear to show what you claim it shows.

The diagonal argument seems to be a proof that there are uncountably many infinite byte sequences. So while it proves that it would impossible to "enumerate" every infinite byte sequence, it doesn't prove that there exists a number that cannot be represented by some infinite byte sequence.

Indeed, I believe the opposite can be shown to be true by constructing a mapping from every finite number to an infinite byte sequence. ASCII trivially provides such a mapping for real numbers, and finite-tuples of real numbers (such as imaginary numbers) can be mapped by alternating digits from each element of the tuple.

Edit: The key distinction is that the set of finite byte sequences is infinite, but countable, while the set of infinite byte sequences is not only infinite, but also uncountable. Which of these two sets is deemed the set of "possible byte sequences" seems to be the critical distinction and the turn of phrase "all possible byte sequences in the universe" seems to imply all byte sequences of finite length.
> Also, the fact that unix uses LF and windows uses CR/LF added to the confusion as well.

And old Macs used CR. And some very rare old OSes used LF/CR!

> I like decreasing the number of cars, not forbidding them at all.

No one plans to.

That aside, cars also pose major problems to all those groups you mention. Elderly people feel unsafe driving and unsafe walking because of cars. They're the primary victims of car-caused accidents. Elderly people in bad health can also be a danger to others when driving.

Kids cannot go anywhere on their own - in large parts because traffic is a killer for them, too. This places a large burden on families, as the parents need to drive them everyplace.

Nearly all of the groups you mention would be better served if you'd remove cars and use the space to improve public transit. For example using dedicated bus lines - improving both speed and - more importantly - reliability. Or build tram lines.

Coronavirus: Amazon removes overpriced goods and fake cures
It is possible to be more materially poorer and happier than a US citizen by changing the deal society makes for them from one of high consumption and high precarity (meaning uncertain job, high cost of housing, expensive transportation, roll of the dice hospital bills) to one of lower consumption and higher social solidarity (meaning less gas, less fancy stuff, less packaging, possibly fewer exotic foods, but secure food, jobs, housing, medical care, and a society that isn't socially alienating).

Obviously, the more materially rich your society is, the better the latter deal is, but happiness comes from feelings of safety, not being overworked, and solid social ties.

From the perspective of a pedestrian this always feels like a really bad pattern. The cyclists are going full speed past pedestrians who might only be a foot or so from them because, after all, they're in a marked bike lane. Meanwhile pedestrians are walking on a sidewalk, maybe not paying much attention, and probably not expecting something to slam into them if they moved over a bit or changed their direction at a crosswalk. A lot of people are not really trained to look both ways before crossing the sidewalk.

Something I found in Japan was that it seemed like abnormal number of people rode bicycles on fairly busy sidewalks. I found I needed to really train myself not to change directions without looking behind me in case there was bicycle back there.

“Under the ‘Prosperity’ set of rules, every player gained each time someone acquired a new property (designed to reflect George’s policy of taxing the value of land), and the game was won (by all!) when the player who had started out with the least money had doubled it.”

This seems like an arbitrary cut-off point. How do we know that if the game were to continue the result wouldn’t end up being the same, with one player still controlling a monopoly of all the properties?

Every possible combination of 8 notes in 12 beats is not infinite. Assuming all quarter notes it's just (8^12)-(8-1)^12 = 54,878,189,535. If you factor in rhythmic variances, the number is much much larger, but still not infinite.

How was the Copernicus' model any better than Ptolemy's?

Over the course of 1500 years after Ptolemy's publication there were more accurate measurements, so Copernicus threw in more epicycles to have the model better match observations, but that's just another layer of indirection. But how are C's epicycles any less 'ad hoc' than P's?

They hardly look any different, at least to a layman:

Yes, mathematically. But copyright requires copying, strictly speaking, so you need a copy from which to have copied.

An algorithm that generates all possible English sentences doesn't demonstrate that I copied this sentence from it, and the balance of probabilities (used in tort cases) suggests that I came up with the sentence, run-on as it is, rather than performing that algo and then selecting that sentence. Moreover 17USC (102? sorry I don't recall) says that media needs to be "fixed" to acquire copyright; so me having to perform the algo makes it no impediment to my owning copyright of a sentence that, if performed, the algo would by expected produce (which is sensible really, perhaps the algo is errant and can't make this sentence, maybe it only forms grammatical sentences ...
I hope that will not hurt them. Imagine that in copyright lawsuite I refered to their midi archive as a source and since that they become in charge for copyright infringement.
