My guess is it's a mixture of analog and digital stuff. On the analog side, there's probably a bandgap voltage reference, temperature and current sensing, soft-start circuitry. It needs to detect the primary's clock and lock on it (probably with a PLL), and adjust the phase as necessary. Then there will be drivers for the power transistors.

The digital side is probably fairly simple logic to stop the chip if there's a fault and restart it if the fault goes away. From the datasheet, there are various different overload states it can go into, limiting power, changing to passive rectification, and then shutting down entirely. So the logic would need to manage these states.

There's always the possibility that they threw a microcontroller in to handle this, but it seems like overkill. Also, I didn't see anything that looked like ROM. So I think the control is hard-wired.
Inkscape: For professional print I can't answer (never had to use CMYK), but Inkscape works well enough for 99% of people who need it IMO (web developers, logo designers, CNC/Milling)

Gimp: Agree, most features are there but finding them is a chore

File sharing: Illustrator uses .ai files which are .pdf (compatible with inkscape), can't speak about .psd compatibility with Gimp, never tried it

Audiovisual: DaVinci Resolve is awesome, and adequate for most if not all home users

Development: I'm assuming you mean embedded development, this relies on support from the vendor, community can't do much about this. Most development are not embedded developers, and in my experience boards by SiLabs worked pretty much out of the box. Obviously anything web (except ASP I guess, I may be wrong) is a breeze on Linux

Regardless, the normal user needs none of this. They need a web browser and an office suite. The Linux ecosystem needs a more intuitive office suite, but libreoffice is good enough and Google Docs/Office365 online work for many people too
Playwright 1.0. Cross-browser testing and automation library for the modern web
Yes, I agree. These days I find it harder and harder to consume long-form content. I have to consciously tell my self "Hey, you're going to finish this paragraph," which is such a depressing thought to have. The web has turned my attention span to mush...
I can't agree with author's point. I'm doing lots of job interviews as employer and also taking some interviews as an employee once a year to remember how it feels on the other side. It is plain difficult to switch context from answering someone's hard and potentially life-changing questions to asking my own. When candidate hears "do you have any questions?” their first reaction is "Wow, I've made it, it's over!". So I'm giving my candidates extra minutes to relax and remember what is it that they want to know about company and working conditions.

Good tactic is to have a prepared list with you, but it is a knowledge acquired with tens of interviews, not something any high-schooler doing every day.
Not that I’m aware of, but I’m sure I do in some cases. I try, and I’m a vegetarian because of view of factory farming for example.

Maybe Tesla is no worse or better than the other companies. That’s one issue for me, but there is another. He doesn’t appear to be in control of himself. It leaves me with very little confidence in a company that I would be spending ~70k on their product with the expectation of high quality, and good support for 5-10 years.

Huntington's disease is one of a small number of conditions that is caused by a single-gene defect (along with haemophilia, and a few others).

It's very rare.

What is known about mental "illnesses" are that they sometimes manifest when certain combinations of genes are present, but not always, and when you look at the details of cases you can pretty much always find an outer-world factor that triggers the state (e..g, abuse, trauma, neglect etc).

So we're talking about very different things.

I agree with other commenters here that a lot of it could be conditioning, but I've also found, like you, that even handwriting on devices is lacking compared to doing it with pen and paper. My personal theory is that it might have something to do with the ability to reason in a more spatially oriented way when we use pen and paper to write things down.

This of course depends on the context, and the 'lunch' question won't always work. For example, if you feel that your interviewer lacks any sense of humour, or is the type of person who would judge a lot questions as 'stoopid', it may be better to skip it (and for that matter, maybe also skip that job)
> you have an &Cell<String> (aliasing mutable reference to owned string)

Is this really an accurate description of what this is? This sounds a lot more like RefCell to me (what would you call that?). Cell seems more like “an aliasing container that holds a particular owned value”, which might sound like gibberish to someone familiar to Rust but makes it clear to me at least that it really doesn’t actually let you grab a reference to the thing inside of it and get away with it.
It's not over yet. Sweden's idea is the deaths under the curve are likely to be the same everywhere for the next 12-18 months, so they are frontloading them without crashing the domestic industries while trying to keep hospitals from being overloaded.

The strategy can't be judged for quite some time.
PayPal won’t let you add a TransferWise account, for unspecified reasons.

At least that’s the case for UK/EU. There are some reports of people being able to add one in the early days - but now it’s like a blanket ban.

It could be because the address of the TW bank account is in New York, and they require a domestic address.

Every time I call up I get a different reason - but the result is always the same. “TransferWise bank accounts are not supported”.
GoatCounter is a pretty straightforward option.

Genetic evidence suggest that the human population was bottlenecked to 3,000–10,000 individuals about 70,000 years ago. Not all that much time has passed since then, evolutionarily speaking, and whatever genetic predispositions were present in that tiny population are probably mostly still kicking around the gene pool. A disorder that doesn't cause problems before sexual maturity or that wouldn't pose an issue for a hunter-gatherer in the environment of evolutionary adaptation isn't really maladaptive, and there's no reason to suspect some number of such traits wouldn't be widespread.

It can also mean that the normal state of the brain exists near a small number of other stable modes, and that a wide variety of small nudges would have similar effects. The article mentions that a study of schizophrenia found that it was characterized in part by extremely rare mutations, suggesting that the brain is at an unstable local maximum, vulnerable to degrading into schizophrenia if unbalanced in any direction. Schizophrenia may in a sense be a much hardier fallback mode of brain operation.

The same thing has happened to hosting providers. Sometimes bad police are malicious or incompetent and screw up the lives of innocent people. But that doesn't have anything to do with Freenet, that can even happen to you driving down the street when some dirty cop needs a bust and decides to pull over a random car and plant drugs on it.

The answer isn't to never do anything, it's to fix the systems that oppress innocent people for no good reason. And in the meantime you can't live your life in fear of low-probability oppression by defective authority figures.

Same here on bringing notebooks to meetings. I didn't for a long time, but I picked it back up recently at the urging of a friend, and I've found myself really enjoying it.

Hmm... as an engineer in industry, if I decide I want to take a walk in the middle of the day, I make sure I don’t have any meetings, then I get up and leave. There are a lot of differences between academia and industry, but this isn’t one of them. I can’t imagine working for a company where I was worried about something like looking out a window, or not appearing to be working.
To each his own, I guess. With the exception of search, I can do all of those things more easily in a physical book than electronically — I find that the physical motion and context helps me remember things.

I replace searching with maintaining my own comprehensive index. It forces me to think about what I’ve read and consider the situations in which it might be useful so that I can file it away correctly. I read fewer things this way, but they stick in my memory better, for probably a similar net result.
I’m glad that this gives better results than screenshots of code but, to be honest, a bit saddened that it has to exist at all. Twitter, I get a little: it’s meant for short thoughts and can’t really work well for code, but Medium (for example) not supporting code is hard to understand.

By changing the narrative all kinds of things become possible. We see today that society can eat trillions in economic losses to save people from a virus. We can replicate this communication structure to deal with longer-term threats to the survival of our species. It is all about building up the political momentum that gets us a moonshot.

Once we are pouring resources into this project perceptions on what is acceptable energy use will also change. People will see society rowing the boat in one direction, and outliers rowing in the wrong direction (excessive emission) will be scorned.

Changing the narrative to terraforming has the potential to unite mankind, while the climate change narrative has been divisive as pollution becomes a commodity to barter for. With enough cleverness in how the idea is presented the money allotted national defense can be re-purposed for climate defense. The 'creating jobs' narrative can also be utilized. - We just need to start talking in this way that I'm prototyping here until it catches on.
I agree with this, I can pinpoint the one question I didn’t answer correctly in one interview once. I was doing well and passed through everything until it came to hr asking about a 5 month break and why I left a company without another job. The hr lady prompted me with what to say “was it so you could do some travelling?” And I replied that I just needed a break and took some time off. She prompted that I must have done some studying, again I just said no and that was it.

My answer didn’t fit the social norms so I was canned.

I think part of it is that paper is completely unopinionated: all it’s doing is holding whatever marks you make for later. That means your brain has to do the work of deciding what marks to make and their meaning; the more work your brain does on any given task, the more memories there are for you to latch onto when remembering.

I don't disagree that it could be conditioning. You make really good points about the benefits of doing things digitally. At some point I really need to spend a few months going all-in on doing it digitally and see if I can make it work for me.

Something like a notebook/worksheet where you can change something and then see how the changes propagate is definitely an easier way to understand something like rotating/balancing binary trees than trying to do it on paper.

I agree that Freenet allows publication that's both anonymous and not readily censurable. What it doesn't allow is anonymous access, except in the sense of plausible deniability that depends on highly technical arguments.

Tor actually does provide anonymity through onion routing. It's not effective against global adversaries, and doesn't claim to be. But it's hard to imagine how any low-latency overlay network could resist global adversaries. Chaff, caching and mixing would help, but they aren't that practical or effective unless you accept greater latency.

Well, I'm thinking from a sort of low-level "what assembly does it generate" perspective, and from that perspective you can treat `&Cell<T>` almost as its own type of reference, as if it were `&cell T` or something – in other words, a way to represent an aliasing mutable pointer in Rust's type system. After all, you can create a 'Cell reference' to any object, without actually creating a Cell in the first place, by using `Cell::from_mut` to go from `&mut T` to `&Cell<T>`. And all the read/write operations on Cell compile to the same assembly as directly reading or writing a pointer; it's just that the set of operations available is restricted for safety.

From that low-level perspective, `&RefCell<String>` is something silly like "a reference to a structure containing a string and also a borrow count". ;p
By all means, then, go for it.

Me, I'll run my Freenet nodes in anonymously leased VPS, and access them via Tor.

But actually, I won't, because there's not much of interest there.

Impressive research work (and results)!

I actually went through the same experimentation when I worked on the fonts and the website at https://int10h.org/oldschool-pc-fonts/. I ended up with a slightly different solution - the Bits'N'Picas converter, which works very much like potrace-pixelperfect, and takes either .png or actual bitmap fonts as input: https://github.com/kreativekorp/bitsnpicas.

What would be ideal is if the bitmap strikes themselves could be rendered in the browser - not really a tall order since they're part of the TrueType specs, and a rasterizer is supposed to use them when they exist. Unfortunately, it turned out that most browsers run the OpenType Sanitizer on the webfonts they parse, and it removes certain tables including the ones that specify the bitmaps. :(
It's header only, good start and makes it worth a second look.
Looks like there's a decent overlap between state tax burden and whether they're 'donor' states in terms of federal dollars. Those that have higher tax burden tend to be sending more $ to the federal government than they receive back. CA historically has been this way, though recently it is about breakeven.

"You may not use Amazon Lightsail in a manner intended to avoid incurring data fees from other Services (e.g., proxying network traffic from Services to the public Internet or other destinations or excessive data processing through load balancing Services as described in the Documentation), and if you do, we may throttle or suspend your data services or suspend your account."
The fact that hospitals aren't pouring new Covid patients out of their ears. Major hospitals are handling lots of cases, and have many more than one hundred employees. They're not hotbeds of transmission, from what I've seen.

You're certainly at more risk in a hospital than at home, but it's not that crazy. Since it seems like you're in the bay area, consider that for the chance to even be 5%, something like most new Covid cases in the bay would need to come from hospital employees or patients. I don't think that's happening.
Having read through the README, I'm not quite sure what makes this perform better than other systems.
I can see that it will perform excellent when iterating over a single type as all entries for this type are next to each other. However, for each meaningfull operation you are likely to combine at least two different types, which means data will have to be read from different locations, defeating the purpose. You could put more data in a single type (for the example from README, you would put velocity and position in a single type) but than you are back to hand-tuning your data types as you would in any other system.
It still looks like an interesting library, but if there are any inherent performance benefits I am failing to see, I would love to hear about them.
And once there, you can also code in emacs too. Imho.
Honestly, it's just not for some people. And that's ok.
