> It's definitely good and worth exploring in the future. There will be time to explore how to have smarter tools that can be used with a less general skillset can be developed. There will also be time to explore how to develop specialized and narrow curricula for such things - itself not a trivial task.

This will happen soon or not at all. The AMA and its equivalents worldwide have a very consistent attitude to anyone, anywhere being allowed to do anything a doctor can do. It should not be allowed. Psychologists should not be allowed prescribe; nurse practitioners should not be allowed practice independently under any circumstances, etc.

The fixes to that design would be straightforward. For example, putting the backup generators on a platform so they wouldn't get flooded.
It's not just bad for the solderer.
It will contaminate areas around your solder area (do your kids ever do a project on your workbench?)
And at end of life, lead is a problem in land fill sites and in e-waste recycling.

Indians (including children) desoldering components from imported e-waste have high blood lead levels:

Not in Spain. I remember the change at around 2003/2005, where the seller just gave me the lead free version.

For what I remember, the lead free had a higher melting temperature. At least back in the days.

Took one week to get used to.
WHO’s statement itself says that the mask is helpful when you are caring for someone with a suspected infection, therefore it admits the mask can provide some level of infection protection. It likewise says the mask should be worn by someone coughing or sneezing, showing that it protects others from your germs.

The obvious answer to the “wearing masks in a wrong way” is to teach people to use and dispose of them correctly, just like we don’t dismiss hand washing because many people don’t know how to do it.

I think these statements by health authorities are simply because there has been no RCT of mask wearing among the general public and for them lack of evidence is equivalent to evidence of absence.

The travel ban bought you time.

But you had to go into lockdown, and shut down the borders everywhere. This is what Trump failed to do.

The virus actually came in from Europe. And when they finally shut down travel from Europe, and everyone immediately flocked home, then this caused the east coast to explode in infected cases.

And New York was just a Petri dish, that the virus was incubating there for weeks.
Most people who get put on a ventilator die under the best of circumstances.
Yes, look here, CodingHorror's (Jeff Atwood) blog:

https://blog.codinghorror.com/the-rise-of-the-electric-scoot...

the comments in the comments section, are from Discourse. Here's that Discourse forum: https://discourse.codinghorror.com/t/the-rise-of-the-electri...

A difference between Talkyard and Discourse, for blog comments, is that Talkyard is threaded, like Disqus. So when people start talking about different things related to the blog post — start different "sub topics", then, with Talkyard, each such sub topic gets its own sub thread,

... Whilst with Discourse, all sub topics are mixed together into one single flat layout.

And, with Talkyard and Disqus etc, the more interesting (more popular) sub topics are shown first, whilst with Discourse, it's whoever happened to type the first comment, who is shown first.

Some decent options in this thread, I thought I'd add some general advice, which I could have used in the past.

Firstly, figure out if you want / need a neck rest. This turns out to be important for me, and I would not want a chair that doesn't have one (this point could be expanded with exceptions).

Next, adjustability is key. Some things are standard (backrest angle, height), but many are rarer. For me, being able to adjust the height of the armrest was eye-opening. Without this, you will either slouch in the chair, or hold your elbows in the air, neither of which are ideal.

Lastly, a word about sturdiness and durability. Some chairs start to misbehave as they age, e.g. I once had a cheap office chair which started to "list" slightly. I didn't pay much attention until I noticed frequent cramps on one side of my back, and realised it's because I'm sitting at a few degrees angle to the right.

Overall my advice would be: get the right chair (for you), sit correctly in it, and do plenty of exercise. The best chair in the world doesn't help enough if you sit for 14 hours every day, without any of the latter.
I'm a little surprised someone with as solid a reputation as Ben Hencke wrote all that and didn't bother to dedicate a single solitary sentence to supporting the claim that leaded solder represents an actual threat to its user. Here I was, getting ready to point out flaws in his sources but not only doesn't he have sources he doesn't even have claims. The whole article is him disproving the myth that lead-free solder is more dangerous than leaded, which, granted, is a good point but he forgot to back up his thesis at all.

Leaded solder is not even slightly dangerous to its user unless you make a daily habit of soldering for hours and then eating without washing your hands. Leaded solder does represent an environmental threat. Fortunately most manufacturers have switched to lead-free solder and the amount of lead put into the environment by hobbyist solder is best described as "fucking infinitesimal".
Would you be interested to launch translations of some of your books? I would love to make these technical books available in French and Esperanto.

I know the Rust book is already translated in some languages. I even started the Esperanto translation myself[1], but had other priorities in the mid time. Doing that in spare time doesn't help to accelerate the process, but I already achieved the translation of the Lua reference manual this way.

If you are interested, just send me an email through mathieu at culture-libre dot org, or reply to this message with some instruction on which canal you would prefer to use.

They asked for evidence. I did as much, explaining a very, very basic concept in medicine, "sterile technique," and how even that can take years to get right. And was told, in response, that I'm just imagining reasons to object. Evidentally, keeping tools sterile in medicine is something I just conjured up!

Perhaps you should take your own advice, rather than responding with personal vitriol directed at the users countering your point.
I just bought a used/refurbished one from Madison seating for about the same price as I could find a used one on CL in SF (~$400). I've been using a Leap for years at the office and swear by them.
He wasn't acting on it, and his lack of actions and untrue statements are part of the reason there are so many stupid conspiracies going around.
Regular JavaScript functions work as if there is an implicit "this" parameter (which gets the value from the left-hand side of the call expression rather than the argument list). Fat-arrow function on the other hand does not change "this", which means the "this" binding inside a fat-arrow function is the one from the containing scope. But in both cases the scope of the "this" binding is lexical.

Dynamic scope means something different. Dynamic scope means that a variable binding from the call site is visible in a called function and down the call stack. This is not how "this" works. The "this" binding at the call site is never visible inside the called function, unless the called function happen to be nested inside the same lexical scope.

"this" is confusing because it gets rebound at every call, even if the function is not called using dot expression. But it is not because of dynamic scoping.
"Zen and the Art of Motorcycle Maintenance". I couldn't stand the insistence on the strong distinction between romantic and classical attitudes.

I think the best way to understand "Dune" is in historical context. Few SF books before then considered the ecology, or used Middle Eastern influences. These fresh ideas bowled over a lot of people at the time.

I re-read Dune when I was about 30, and thought it was nothing special, and a bit simplistic. Thing is, its existence helped change SF to expect more complex stories.
This and don't eat, drink or smoke in the lab. I remember my material sciences professor relating the story that blood lead levels for a certain group of pieceworkers dropped considerably when they banned smoking at the workplace.
Here's what makes sense to me:

* The single most effective intervention we have right now is staying home and avoiding every unnecessary contact, as authorities recommend.

* Worn carefully, several kinds of masks probably have a range of marginal positive effects.

* BUT recommending them runs the risk of (a) people over-relying on them and not following isolation protocols (b) people wearing them incorrectly for a mix of less effective benefits and added risks (c) contributing to a run on masks which constrains supply for medical workers where the benefits are more critical.

If this is all true, it can simultaneously be the case that official guidelines against masks are reasonable recommendations and that it's also a reasonable recommendation to wear masks (on top of other more important precautions).

I'm sure that masks are not the sole factor in gentler curves in those countries. They do seem to be a common factor.
Environment is huge. Listen to this guy!

If you're doing this in your kitchen, stay far, far away from lead.

If you're doing this in your commercial building's electronics lab, where food and drink is prohibited, and there are only electronics people around... leaded solder is going to win.

If you're doing this in your factory, where your processes are tightly dialed in and you're moving mountains of product... now you can use either one just as easily, so there's no reason to risk lead unless the customer or application demands it.
Bit of a win/win though. Either the oil age ends before the ME runs out and we potentially avoid an environmental disaster, or it doesn't, in which case our reserves might prevent a strategic disaster.
Yes, the melt temperature is slightly higher, and i have difficulties to melt it with my old solderer.
I'm down with the hacking aspect here, but why would I want to render comments in italics? Comments are often larger pieces of natural language, and there's a reason we don't typeset our books in all-italics - it's harder to read.
Can you please elaborate on that? This was actually one of my concerns since I would assume the "flavor(?)" is coming from whatever is in the water.
So where does the danger come from with leaded solder then? Skin contact?
A kratky setup is cheap, but even that wouldn't be $25.
I'm torn between a pleasant UX and a portability/low bus-factor of the system I'm using. I don't take any long-term notes in LT though, just some quick ones from text books. I eventually plan to transcribe those somewhere else — still looking for the perfect app to use for the Zettelkasten method.

Does anyone know if there's any truth to ideas that certain metals like copper are "antibacterial"?

I am worried because I have seen stories (e.g. [1]) that claim that masks incorporating copper can be effective against the virus (never mind that "antibacterial" apparently also means it can fight viruses, which makes no sense). Basically, I am seeing an increase in people selling "masks" that are not approved and that has me worried. I would like some information about whether there is any science, for or against, to the idea that particular materials, especially metals, have any kind of "special" effect against bacteria and viruses.

Apple would love more lock in and transforming Macs into giant iPhones with app store only apps.

However, breaking compatibility with Windows and Linux would be a terrible idea. People would flee to other platforms leaving Mac for those who are already locked in, like iOS developers.

People care most about running their software to do their work, than what os they use.
I still absolutely loathe teams. There is no way to get it to show you have unread messages (the red dot of slack). Notifications do not work reliably. When I am in a Teams channel I miss notifications from the Chat channels, and vice versa.

Absolutely agree. Modern operating systems are utter beasts when it comes to complexity and are far less predictable than simpler solutions. There are reasons microcontrollers are still everywhere.
Hi,

Your comment fails to offer a counter-argument to the comment you are replying to; you are just repeating the position that the comment explicitly refutes.

> Or are you stating that the WHO is lying?

In fact, the site linked in the comment explicitly states that.
To some degree, probably.

Structs have many limitations though and two different argument passing semantics in the same language mean more complexity. Also you may be lucky to eliminate allocations in your own code, but what about libraries? Existence of GC shepherds programmers and library creators into heap allocation. You don't need to write new explicitly to allocate on the heap.

Also high level languages with no GC make manual memory management much more usable and provide way better ergonomics in this area, just because they have to. E.g. automated reference counting, ownership/lifetime control, move semantics etc.
How is farm labor implicitly exploitative?

Pay them $100/hour and provide breaks and good work schedules and watch people flock to the jobs. Some people may be unable to afford the new prices of the produce, but it is what it is.
A lot of it has to do with the platings on component leads/terminations. Within the last 10 years it's become clear just how well component manufacturers have dialed things in. They had to go pretty far to do that, though. I know the amounts used are miniscule, but it still amazes me that cheap commodity ICs have leadframes plated with palladium and gold, and dirt cheap resistors have ruthenium in them. (All very, very expensive noble metals!)

I find the not-really-locking arms on the Gesture infuriating - this is my chair, i sit on it each and every day and after some initial adjustment i don't expect it to move, like, at all :/
Wow, didn't realize that these were actually recommended. I have grown to dislike these so much because these chairs are in every company I've worked for. Ugh.
Sibling is correct. Plenty Ag acquired Bright Agrotech for people and IP. Bright was profitable but faced a difficult time scaling. It’s business model depended on individuals getting enough capital to start a farm. Many farms were profitable, but not all, and it’s difficult finding lots of people wanting to take out loans to start farms and banks didn’t understand the idea of indoor farms. Plenty Ag raised $200 million (largely from SoftBank) and needed to get a jumpstart on working tech and experts in the field. I’m still hopeful that once indoor farming tech keeps improving (based partly on large investment in the Plenty’s of the world) and banks accept indoor farms that individuals will be able to easily run indoor farms. A big part of that would be more labor automation. Plus if an asteroid ever hits Earth knowing how to grow indoor food would be valuable. ;) More realistically (hopefully!) indoor farming will be critical for colonizing Mars or asteroids. Long term, indoor farming and vertical farming will be critical technology for humanity to perfect, IMHO. An example (and fun) tech innovation was Bright’s invention of “water cooled LED towers”. That’s an early “Google style” innovation akin to using trays of cheap servers. Regardless hardware innovation takes massive amounts of capital. I’m hoping the Plenty Ag people are able to make fresh produce “a thing”! Edit: link to water cooled led’s https://info.brightagrotech.com/hubfs/Downloadable_Guides/Co...

And then have to live with asking yourself "could I have done more?"
Let me count the ways.

1. Long state of indecision. For a very long time, as the news from around the world brought images of falling skies, the Finnish government actively avoided making any decisions. G: "we defer to THL". THL: "we defer to government".

2. President had to intervene to get the government off of their asses. How messed up is that?

3. Artificially limiting the supply of ICUs. Of the 300 units in the country, half are earmarked for "not to be used for COVID-19 cases".

4. Completely ignoring the effect of people returning from their holidays. That's 200k potential transmission vectors, not taken into account at all. Until it was too late.

So the people who were supposed to be in charge have shown nothing but incompetence and avoidance of responsibility. The measures that are in place now seem good (quarantining an entire province!), but the handling of the pandemic until very recently was nothing short of disgraceful.

This consists of two layers of gauze enclosing a flat oblong piece of absorbent cotton 6 inches by 4 inches. It can beeasily made by cutting the usual surgical gauze (9 inches wide), as supplied from the shops, into strips, each measuring 3 feet in length. Each strip is then doubled lengthwise so as to contain in the middle a flat piece of cottonwool measuring 4 inches by 6 inches. At either end of the gauze two cuts, each measuring 15 inches, are made. Thusturning the pad into a three-tail gauze bandage, with the central piece of wool for covering the respiratory entrance.The upper tail of one side should be passed round the side of the head above the ear and tied to the othercorresponding tail. The lowermost tail should in a similar manner be passed under the ear and tied to the one on theother side, while the middle tail should be passed over the crown of the head, so as to fix the pad and prevent it fromslipping down the neck

In Australia a similar scheme (almost exactly the same by the look of it) has recently been implemented.

Needless to say, people complained about being confined to their 4 or 5 star hotel room.

I understand the boredom, but people had a week to get back to Australia after the government recommended it, and it seems a decent trade off between individual freedoms and killing people. For context, in Australia over 50% of the current covid-19 cases are from people returning from overseas[1]

Just shut down everything, but don't delete existing data written to disks. That can cover a wide array of budget problems. If you set a budget like that you really do not want to go over it and any potential loss from customers is not as huge as going over that budget. At least have that option.

I sometimes for example fiddle with Google APIs. I do not even have customers so don't really care if things will stop working, but I have accidentally spent 100 euros or more. I have alerts, but those alerts arrived way too late.

> Wu explains to the French doctor his theory that plague is pneumonic and airborne (...) And the French guy humiliates him . . . and in very racist terms says, ‘What can we expect from a Chinaman?’ And to prove this point, [the French doctor] goes and attends the sick in a plague hospital without wearing Wu’s mask, and he dies in two days with plague.

Maybe we're like this French doctor, and that this is still the reason why we don't wear masks in the west? A widespread practice in several East Asian countries - but what do they know?
Don't be lazy. Just Google search SARS-CoV-2 on surfaces and you will see that Coronavirus lasts about 4hrs in Copper, while it can stay one day in Cardboard and several days in Stainless Steel and Plastics.

So, yes, there is something special about copper. But copper is not a virus killer (i.e. kills them at contact), it justs seems that viruses don't survive that long in copper.
This has been known since ancient times (where Copper pantry and utensils was preferred over Steel).

The New England Journal of Medicine. The scientists found that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was detectable in aerosols for up to three hours, up to four hours on copper, up to 24 hours on cardboard and up to two to three days on plastic and stainless steel.
