That same engineer also said the following

All passive USB-C cables support PD 2.0 or 3.0, all charging features. The only things a cable needs to need to support PD are:

Vbus wire
Gnd wire
CC wire
Therefore, all USB cables, even the lowest end USB 2.0 cable support USB PD. You don't need an identifier chip to support basic USB PD charging.

Literally it's just the CC wire that goes end to end that enables USB PD charging from one end to the other.

USB PD is supposed to be backward and forward compatible, and a USB 2.0 cable can't actually differentiate itself as a USB PD 2.0 or PD 3.0 cable, since chances are it doesn't actually have an identifier chip. Your basic cable (which the Anker is) should work all the way up to 60W with PPS.

PPS also doesn't matter. A USB 2.0 C-to-C cable is supposed to support PPS.

-----
In other words as long as you have any proper usb c cable (spec compliant) and a usb c Pd charger with sufficient power output, everything will work.
Depends on the school culture, the professor teaching, the particular language being used... there are a lot of factors!

I did both my undergraduate and MS in the past decade, worked in academic research for a few years, and am currently in a PhD program. At the schools I've been at and schools I know well due to friends/collaborators, I think what I said still tends to be true for mandatory ("core") classes.

You are right, however, that students who choose to take an elective in a statically typed functional language are probably more likely to come away with a healthier relationship with their compilers, but this is only a portion of all students.

Plenty of good suggestions so I'll just add: draw every day. Guided resources are good but nothing beats just doing it a lot. Start with some simple still life. Get a big pad of paper, an easel if you like, and some charcoal. Each time you do a drawing, to begin with, just focus on one aspect of it. Try to just work on getting the perspective right, keeping in mind a vanishing point. Next just focus on light and shadow. Practice drawing circles. Lots of them. Over and over. Draw 100 vertical lines on a sheet as straight as you can. Drawing uses specific muscles and requires muscle memory to take the line you want to draw in your mind and translate it onto the page. The only way to build that is by just doing it a lot. Next take your still life objects and draw it from the perspective opposite where you're sitting, accounting for the light and perspective. Add in some more difficult things like fabrics or objects with fine texture. Your drawings will suck at first. They always do. Save some as you go as a sampling of your progress. From time to time compare your latest ones to your first ones. What's improved? What hasn't improved? Go outside on some lovely day and find a nice comfortable place to sit and just draw whatever you see. Doodle when you're on the phone. Draw in the margins of everything. Just keep drawing.
This is misinformation, the USB-C connector design is more robust than the lightning port. The reason there's a "tab" in the middle of the phone connector is so that the cable can grasp onto it with spring-loaded contact areas. In the lightning connector the spring-loaded pins are in the phone instead of in the cable, these spring loaded things are what breaks in the connector (if it isn't just full of lint which you can get out). The reason why it appears the lightning connector is better is because Apple manufacturers high-quality devices.

Lightning is designed to wear out the contact, USB-C is designed to wear out the cable.
>> It’s pay to play, and if you don’t want to pay then… don’t, nobody puts a gun to your head any forces you to support the iPhone

Right? If you don't like their monkeys then don't join their circus! Apple is spending billions of dollars to create their iPhone market that these people then want to tap into and profit from for free! Apple doesn't get paid unless you get paid, distribute your app for free and you don't have to pay Apple anything. Oh, you want to make money? Then you're going to have to pay for that!

If these people don't like it then I suggest they try distributing their software via Walmart, Gamestop, or Staples. Wait, what? You can't access their stores for free to sell your stuff! Say it ain't so!

Frankly I'm tired of this juvenile discussion. These people obviously have no clue as to how retail works and can't see that Apple has actually cut them a hell of a deal! A better deal than you're going to get distributing any product via a traditional retail channel.
Ok. Go back 5 years and standardise on the ubiquitous usb-mini — usb-a solution.

I gave up and, luckily, a few hours later found the mistake.
I don't know if you've seen it, but putting the blame on fat was an orchestrated effort by the sugar industry: https://www.npr.org/sections/thetwo-way/2016/09/13/493739074...

The appeal to naturalism is kind of iffy, though. The kinds and amount of fat we eat might be substantially different than many of our ancestors. I'm not making an argument either way, just that I doubt modern food resembles ancient diets.
I'm aware that medicine hasn't discovered a bright line between what's healthy and what would likely cause fetal alcohol syndrome or premature infant death. While any lawyer worth his salt would attack the lack of substantive medical literature, judges and legislators have now and in the past invented bright line tests that, while not wholly accurate, are "good enough" to account for a general decision (although I don't agree with that kind of reasoning myself).

In my example, I could have also used tobacco in place of alcohol, but the point I wished to address is whether the health of an imminent child trumps the rights of a mother or vice versa. If one accepts the affirmative position, then a woman does not have a right to her own body. If we accept the negative position, then the child will become a long-term burden on the medical system at the expense of others.

May I suggest you don't license the work in a way that allows it to be commercialized without your explicit permission and handsome compensation to you and any other contributors. You'll need this to be sustainable and it'll be incredibly frustrating if a company de-facto hijacks the development and takes it in a direction you don't expect or want.
I think this is a much more productive line of discussion than just asking not to distribute software.

For example, distros don't provide the guarantees you're talking about - they arbitrarily introduce fragility (for example, by requiring shared dependencies that may have conflicting versions) and don't keep up to date with the upstream software that has bug fixes. That's precisely why software authors prefer to release as flatpaks - regardless what distro teams claim, bugs and crashes manifest as problems in the distributed software (not the OS) and are reported to the upstream authors whose users demand fixes.

In short, distros can't provide assurances that software will work. They can't fix it if it's broken, either.

I disagree that it isn't the software authors' job to distribute their software and fix bugs for their users when using it. The only folks who seem to insist that this is The Way Software Should Be Installed are distro authors and a tiny minority of users who are ok with broken code shipped by their OS authors instead of working code by the original authors.

Imagine if an app crashes on Windows or MacOS, a user reports the app crashed, and the author replies: "Sorry it's Microsoft/Apple's fault for shipping broken software on their end, complain to them instead." Because that's the same quality of user experience when a distro ships older versions of software or try and link against invalid dependency versions.
The idea that TSMC is the main reason why China wants control of Taiwan is ridiculous. It factors in of course, but the issue goes way deeper than computer chips for China. One, it's a point of national shame that factors heavily into CCP propaganda. It's seen as a loose end from the Civil War. And two, capturing Taiwan would give the Chinese navy unlimited access to the Pacific.
At $30/user/mo, you're getting into a fair portion of a dev's salary, and "Run Gitlab" is competitive. But then instead of a support person who is going to give me the runaround, I have an actual engineer who has the power to actually fix things.

But it's also not "$30/user/mo", either. It's that, plus (my salary * time spent on support tickets and outages), plus storage costs, plus compute costs.

The biggest contribution of CERN to humanity is not theoretical physics, it's the engineering progress made possible by the truly exceptional requirements of the machinery of the accelerator and all the supporting infrastructure. Ultra high vacuum, specialty detectors, electromagnetic components, control systems, cryonics, new alloys etc.

All the know-how and human capital generated by these megaprojects along with a better understanding of fundamental physics is transferred into practical applications a few years later. I can understand how a physics phd might not be exposed so much to this aspect of the project, but the societal benefits are very real despite being hard to quantify and track.

Haskell does have advanced tools though. Stack / cabal, haddock, htest can be comparable to Rust’s tooling. Haskell’s LSP is making rapid progress and there are many formatters and linters.

Tooling still has a way to go, but I don’t think that’s all. Haskell’s abstraction is just too much when you need to design something which is ultimately kind of straitforward, and most apps are (design app, game, utility app, web server, etc.)

I do think Haskell is more than a research language, it does have some use in practical, mainstream programming. In particular, Haskell is great at anything which is “input to output”, like compilers or document converters. Or in a program which is ultimately complex, and not just for optimization but “math” complexity, like math programs or simulators. In those programs the implicit laziness actually comes in handy.

But Haskell for a real-time video game or editor, and you’re just wrapping everything in an IO monad or some restricted stateful equivalent, and executing most of the instructions in sequence anyways.

> I fully expected to spend time "fighting with the compiler" when playing with Haskell.

Well that's part of the problem, is what I mean. If you look at it as a "fight", that's often how it will feel!

That said, as I also said, Haskell's error messages tend to be more frustrating and mysterious than they ought to be.

> I'm not sure if this is just a fact of life about FP or Haskell, or if it's something that could be improved on.

No matter the cause, it can certainly be improved. Programming languages have largely not focused on user-centered design. Fortunately, there are some recently formed workshops seeking to get the ball rolling in that area, so hopefully over the next couple of decades we will see some significant shifts in the ease of use of popular languages!

That said, I think if you had tried a different statically typed functional language (OCaml or Scala, for instance), you would not be quite as frustrated. But then Haskell has my favorite type system among common statically typed functional languages, so there's really no winning haha. Hopefully it will improve over time!

> Of major U.S. cities, Salt Lake has among the lowest per-gallon water rates, according to a 2017 federal report. It also consumes more water for residential use than other desert cities — 96 gallons per person per day last year, compared with 78 in Tucson and 77 in Los Angeles.

I was in Utah a couple of weeks ago, and I was surprised by the relative absence of water use reduction techniques. The hotel I stayed in had a “waterfall”-style shower (it was not particularly fancy, and I did not pick it specifically), and I saw multiple over-watered flowerbeds while walking around (including one that was literally filled with water and spilling onto the sidewalk.) And quite a bit of dust in the air.

Correct. The theory of evolution explained selective breeding.

At the velocities the a/c would reach over the USSR, if it had a mishap the environment would be so severe the Soviets wouldn't even be able to determine from the wreckage if it was manned at all.
Recessions are when you find the best VCs
If you are not going through YC and raising your own funds, recessions are a great time to vet VCs.

Most VCs during this time quiver and grow timid and scared.

They do not have confidence in their network, in their mentorship or their determination.

However there are a few VCs who are not like the above.

Finding them is easier during this time because everyone else is not pretending.

Find them and raise capital from them. One of the many boons of a market downturn for building a startup.

> We have so many problems where physics is needed (energy production to start with, and then exploring biology), the money should go there instead. Even if it means having less particle physicists the same way we have less philosophes.

This is a false dichotomy; we have the resources for both and more. Perhaps a lack of willpower/grit/political incentives in some arenas, but none of that is insurmountable.
> Without a doubt 5 years now JPEG XL will become like Opus and set the standard for next generation image formats.

I wrote a little X11 screenshot tool last year; one of the reasons I wrote it is because I wanted to save images as WebP rather than PNG that most tools use, since it's quite a bit smaller. Not that I'm running out of disk space, but it just seemed nice; one of those "no, it's not really needed but it's fun and why not?" weekend projects.

Anyhow, I discovered that loads of stuff doesn't support WebP. This was unexpected as it's been around for ages and supported by almost everything, but things like uploading to GitHub, Telegram, and many services doesn't work. It was disappointing and I had to add PNG support just for that.

I fear that JPEG XL will be in a similar situation in the future, where loads of websites can and do use it for their images, but also loads of services don't support it so it's a lot less useful than it could/should be. I hope I'm wrong.

Aviation is ground zero for that.

Is is telling that aviation’s “sustainable fuel” vision is the same Fischer-Tropsch chemistry that’s been abandoned for everything else because the capital cost of the machinery is too damn high.

Ground transportation has moved on to single-entity fuels that are synthesizable like 1-butanol and dimethyl ether. I can’t for the life of me see why the industry isn’t developing methane as an aviation fuel as it could even be the low cost solution in 2022 if Airbus had developed that instead of the thoroughly pizzled A380.

There are some projects in that space already. Mycroft is one, but it seems slow going and didn't support the 8GB Pi4 when I tried. There was another that just did voice to text and fired webhooks with some of the data; I can't recall the name but it seemed perfect other than needing at least 2 services running (the voice part and your backend).
