I use leaded solder and have for years but I’d love to replace it with something less toxic. The trouble is that lead-free solders I’ve tried require high temp and flow very differently from leaded solder.

Does SAC305 (for example) flow and cool in a similar way to good old 63/37?

It's not mentioned in the article, but this could also be a sampling issue. Samples from previous decades might've been more limited or self-selected. The internet may mean that a broader, more representative sample of the population is being tested, and you're just seeing regression to the mean.
This take really makes no sense at all. Even if you argue that all Elon did is start SpaceX and provide the initial funding (which is undeniable) than you would still have to agree he has been wildly successful as a business person.

Psychologically, it seems quite similar to how people often hold allegiance to any ideological organization despite its obvious issues.
I did this from IT technician to DevOps/Platform engineering. Took about a year of learning and a handful of failing interviews to finally have someone take a chance on me.

I started by first learning what the job requirements are, looking deeper at the software stacks and where they are used. Eventually, I figured out that AWS, Azure, and GCP give you a handful of credits to try things out. From there, I started to learn and setup my own environments. Eventually, I got good enough to understand how to setup my own applications with best practices in mind.

GPT’s vocab size is north of tens of thousands. Included in this vocab are the 256 unique byte values (2^8). This means GPT can already generate/interpret all byte sequences.

The vocab size is larger than 256 (or in your example 2) because some sequences of bytes occur much more frequently than others. This allows the model to generalize more efficiently.

By analogy consider that we think of “words” as atomic concepts much more than we think of the individual lines that make up the letters in a word - even though the former can be thought of being composed of the latter.
Interesting topic but only skims the surface the tiniest bit, and I'd challenge the idea that this is the first time layoffs have become routine in tech. They seemed routine when I first started in tech in the early 2000s, certainly they were routine around 2008/2009. Before being eaten by Oracle, for example, Sun had regular layoffs. IBM was known for it. Microsoft had waves of layoffs in that time-frame, Toshiba, Seagate, Novell, SAP[1]...

One thing that remains true is that tech companies tend to follow peer pressure. Once a few companies break the ice, it's a wave.

All that to say - it might be slightly more flagrant now, but if there ever was a "social contract" it hasn't been kept up by (most) employers for a long long time.

When the article says, “Commercial bank lending dropped nearly $105 billion in the two weeks ended March 29, the most in Federal Reserve data back to 1973,” and later also notes that banks “divested” themselves of billions of dollars in loans, where is the money going?

Are they selling the loans off their books to third parties? Or are they just refusing to make new loans that they would have otherwise consistently made?
>What may be shocking to some people is that this phenomenon applies to people of any gender

My point about what people don't talk about (and what those articles also ignore) is that it's not just men watching porn.

>Easy access to porn is part of the story, of course; in 2014, 43 percent of men said they’d watched porn in the past week.

Pornography is always framed as a men's topic, but I'd argue that's a very incomplete picture of what's going on.

EDIT: Maybe I'm being too euphemistic. My point is that no-one is discussing the fact that young hetero men now have to compete against pornography, and many are losing that fight. This is an enormous power shift that has largely gone undiscussed and many young men are unprepared to improve their chances, since they are ignorant to the problem itself (Parents giving out of date advice, etc.)

Jan Leike's point is a bit more subtle there. He's not surprised it can learn translation with a relatively small number of training examples, but surprised that it seems to know some instruction with no examples.

And just a few Tweets later speculates it's likely because there are examples in the training data, and the success of the model to follow instructions in a non-English language from "nothing" is proportional to the presence of those examples in the training data [0].

I don't think he would disagree with anything in my statement.

Actually it is. There is no good reason scientists should all follow the same course of action. In fact, per your own appeal to statistical reasoning, such reasoning is only meaningful if you have an actualization of the samples. If no scientists ever try the unlikely scenarios then you will always reach local optimum.

What is at stake is "Some scientists should consider FTL travel possible, and give it a go." for such a statement, the argument definitely holds water.

A question to the experienced Anki users:

The recommendation is to learn before you memorize.

Many times I hack the infos (from an article) right into Anki. Now if it‘d want to review the infos in the Anki app, that totally destroys my stats.

>Horseshoe Theory: Extreme opposites tend to look the same. For example, a far-right movement and a far-left movement can be equally violent or desire a similar outcome.

This is terrible political ignorance disguised as "advice". Violence is the most fundamental form of influence, and is not owned by any particular political party or position, nor does the willingness to use violence communicate anything except that group's lack of commitment to pacifism.

This is akin to saying that serial killers and carpenters are basically the same because they both use sharp objects. In fact, you can equate any political position to any other, or literally any sovereign group of people, when you account for the fact that all of them have gone to war or committed some other act of violence to further their interests.

In fact, this is the Fox News/neocon Republican talking point: "anti-fascists are the same as fascists, because they harm fascists"

Does the author really think in such simplistic terms?

It's interesting that many of us here are programmers and understand that debugging becomes exponentially more difficult as you add a number of variables beyond 1 to your deductive tests.

Yet when it comes to the economy, which is the product of an unfathomable number of variables, from the same people there are consistently these confident assessments of why we see x, y, z and what will happen.

It's worth discussing those things to the best of our ability, but we should have a tone of our confidence in these types of assessments that's commensurate with reality.
> reserve requirements limit the amount of loans a bank can make relative to its deposits

Reserve requirements haven’t restricted lending for decades. It’s why they’re zero in most of the world, replaced by finer-tuned capital and liquidity requirements. (And deposits != reserves.)
It’s not all of the Fed’s fault, but they did keep printing. The main culprit though is the multiple administrations who didn’t fully weigh the long term consequences of weaponizing the dollar.

The format is quite old.

There was a has the LHC destroyed the planet yet site created when the media kept that sensationalist lying campaign against turning it on (at the early 2000's), but I think the funniest one was the "how many days since the last Java 0-day" around the time Oracle brought Sun (around 2010, wasn't it?), just because of the sheer absurdity of keeping it static for almost an year and being correct every day.

I remember before those there was a famous "how to destroy the Earth" site, with a status page answering "has anybody done any of this yet?".
This is an interesting theory, but couldn't the opposite happen? As boomers aged, many will have gradually reduced their stock holdings to own less risky assets in preparation for retirement. As boomers die, Millennials will invest the inherited capital back in to the market because they have a higher risk tolerance.
What we really need is finer-grained permissions like “let the OS pick a photo and hand it to the app” and “let the OS pick a contact and hand it to the app” and then require that most apps use that instead of overly-broad permissions that will be abused.
You don't need to prove everything against a complete spec, you can prove that things have particular properties you care about, from higher level behaviors like user data can only be accessed by the user down to there are no out of bounds array accesses.

You could prove some complex data-structure to be a correct implementation of some logical data-structure and then prove that your service won't deadlock.

There are a ton of interesting, impactful properties to prove that aren't "create a complete specification and prove the implementation refines it", and even that usage I think is more impactful for removing bugs and vulnerabilities than you're giving it credit for - even something as simple as sorting, Java had a bug in their Timsort implementation for a decade which was discovered when trying to verify it with formal methods: http://envisage-project.eu/wp-content/uploads/2015/02/sortin... ). Note too that if you compiled the simplest/easiest-to-understand spec for something like sorting you'd get something like bubble sort, not Timsort, though you are much more likely to want the latter.

> Withdrawing from a 401(k) has no real effect.

Highly disagree here....

First, selling stocks puts downward pressure on price and also p/e ratio. A lower p/e ratio means startups and growth companies trade at lower multiples.

Second, selling bonds increase yields, which means the price of borrowing (interest rates) goes up. When that happens, companies that borrow money (most of them) see lower profits because more money is spent on interest than on investment (machinery, people, etc).

Capital markets are complicated beasts, but withdrawing capital has very predictable effects - we just don't know if the effect will happen slowly or quickly (like in a panic).

One other effect that happens is that as people retire (or get close to retirement), their investment choices become more conservative and there tends to be a shift from smaller, more volatile growth companies to larger, more established companies with good dividends. That shift alone is worth a thesis or two.

As for your last comment, I can't tell from the wording whether you agree or disagree with the PP's comment. However, I would note that since the baby boomer generation is larger than the Gen Z now entering the workforce, that on average, experienced people are retiring at a higher rate than the rate that young inexperienced people are joining the workforce. This tends to result in higher labor cost (fewer people to fill jobs), which, when combined with higher interest rates tends to mean lower growth for a good period of time (measured in years, not months). Obviously there is variability from month to month and quarter to quarter, but the trend is clear (or will be soon to everyone). It's not the 1970's, but some of the parallels will be surprising.
It isn’t about losing data. It’s more about not knowing what is happening or what is not.

For example message sometimes just don’t sync on some devices. Sometimes a 300MB video file is taking just forever to sync with iCloud. Hours! When everything else is working smooth on a 800mbps connection. And you cannot do a thing about it. You write a note on one iPhone and then you don’t see on another for minutes, sometimes hours, or on another Mac. I mean the list is endless. As a matter of fact there’s no versioning either in any of its services that you could verify something.

So it’s not about losing data. It’s about not knowing! Not knowing whether you have lost data, or might lose, or anything about it!

What makes it worse is Apple making every other apps that you could use instead a third class citizen on their OS. So you have alternatives but you don’t.
They did a poor job of qualifying "cheap". They link to a $50 Harbor Freight unit, which is a proper temperature controlled soldering station. It should certainly be made clear that a $20 wand with no temp control is right out.

I don’t quite get the thrust of most of your post beyond that you have a more generous understanding on the quote.

As I get your post based on the amount spent on why it’s bad to dismiss older persons, I don’t think this is really what the article or GP suggested. similarly, I am not sure that it’s fair to say genz often doesn’t do a lot of the mentioned things. GenZ is full of individuals specializing in niche or old fashioned skills and showing the skills off on specific mediums. Coding and repair twitch streams are quite common, just maybe not as much as subjects that are easier to appreciate without much knowledge in the subject. It’s pretty easy for most people to grasp why a contortionist’s skill or someone skilled with sewing has a rare and unique talent. it’s a lot easier to understand what went into it and the precision and the result is very apparent. I think it’s not so clear with subjects like electronics repair as the tech might work afterwards, but there is too much to understand going into it to fully appreciate the result in its own, and thus audiences rely on the presenter to fill the gaps.

The authors examples are good ones if you’re already inclined towards fixing stuff on your own; but if it were me, even with a simple fix like string lights, i’d have a hard time justifying repairs on my own as i’d need to invest into the repair kit and it would be hard to shake concerns on if I did a safe repair or if I made a mistake that needs to be fixed. I imagine it’s like this for many, as even a few years back when I did laptop repair at a university, students (even technical ones) were antsy about such manual repairs and fixes, and often just preferred to put the liability on someone else. for something really disposable like lights, a cheap phone, etc, i can easily get why people of all ages would just prefer a new one.

Soldering is a fun hobby, and i think that the hobbyist community would easily eat it up if they don’t already (i’m positive you can find some electronics repair vids/channels). it is just lacking practical reasons for people to be interested and/or personalities to bring people to it.
As a strictly software person who's been living in the embedded world for a while, developing adequate soldering skills will make your life hella easier. Lots of setup/debugging problems get easier if you can just make the connectors you need or stick a lead in just the right spot.

Being self-reliant for stuff like that is basic productivity stuff.
