Exactly. Essentially the trick is not "use this muscle". It rather is "do this specific movement with this muscle. I can describe it quite simply, but to truly learn it you'll need a biofeedback device and you need to know what you're working towards."

There are a lot of surprising skills that we could learn if we just knew how and put in the effort. See e.g. the blind mountainbikers using echolocation to 'see' the path, or method of loci/other memory techniques.
How do you explain why the vast majority of Russian losses in Ukraine are ethnic minorities, if not with racism? How do you explain those minorities have no representation in government, if there is no colonialism?

Russia is world’s last colonial empire. It’s entire economy revolves around Moscow parasitizing on everyone else.

> "The degree to which humanity runs on tautological reasoning is the part that I find interesting."

yah, this is the amazing part. societies are much more resilient than we might otherwise give them credit for. we can endure a lot of suboptimality and hardship, and even reasoning our way into tenacious consent, because the activation energy for change is so high and the final outcome so uncertain. perhaps this is the best we can do--find stable local optima for limited spans of time.

but regardless, being able to uncover poor rationale like tautologies is one effective tool in the toolbox for reshaping political narratives. it's a slog for sure, but you do sometimes see narratives change (covid response being a vivid example). being indenpendently-minded (skeptical) helps a lot too, as you're not personally invested identity-wise in any given narrative, and are willing to change your mind more easily as new information rolls in.

we have hugely invested interests working against such reforms, but some of these will come to pass one day for sure, just because enough people will be fed up and demand it, despite the personal cost[*].

[*]: most people are wholly unsuited for conflict (even the constructive kind) because it's so uncomfortable and risky, and in developed countries as we're constructed, the payoff seems so disporportionate (a lot of gain going to others, a little going to you, but you seemingly taking much of the personal risk).
I once lost 17kg (50 pounds) by caloric restriction (500cal deficit per day). I’ve got news for you: you will be slightly hungry most of the time. Meals will be the highlight of your day.
So I wondered if I could lose some weight if I teleported on top of Everest and started searching for formulas. Apparently, this question is already answered and the answer is yes - I could lose half a pound.

So yeah, if you have resources to shave off that much of Earth surface, then you have resources to construct a high enough building to lose those 10 pounds which would have been a lot easier.

GNU/Linux takes a similar approach to commands available in user space. IMO, companies are obligated to chase the profit to the detriment of their product being simple, and this is why this naturally occurs.

But at the same time, politicians using social media to continuously publish blatant lies is also not a mechanism for stable government. In the past, this was regulated to a large degree by traditional media outlets being a filter of sorts and not just printing any random direct statement made by a politician.

I think there is a balance between "social media must not interfere with blatantly false statements from politicians" and "social media can ban their political detractors without consequence". The ideal reality would be the public actually holding politicians responsible for being deceptive or treasonous, but that does not appear to be on the horizon either.
Seems like a good article. Stable, wealthy countries like Canada are in the best position to build more housing and absorb migration from poorer regions.
I bet big on Java/Jakarta EE, and the open source application server WildFly, years ago when the web version of Calcapp was born in 2014. I have been very happy with that decision. JAX-RS is a great way to build annotation-driven REST web services with very little boilerplate. WildFly (the open source version of JBoss EAP, essentially) is actively developed by Red Hat, starts quickly and is easy to work with. And the modern incarnation of Java -- with streams and lambdas -- is a great fit for what we do (building a compiler).

The only decision I have come to regret is using JPA, which is short for Java Persistence API (a specification for an ORM -- an Object-Relational Mapping), and where the most famous implementation is Hibernate. As far as ORMs go, Hibernate is probably fine, but I wish I had considered using something more light-weight and closer to the underlying database. As things stand, JPA mostly gets in the way, and I have had to resort to "native queries" (SQL) for our most performance-sensitive code paths.

I don't regret choosing JPA, as much as I regret choosing an ORM.

Also, as others have alluded to, Java is a stable choice. At the same time I chose Java EE and PostgreSQL, I chose AngularJS for our front end, which has been fully superseded by modern versions of Angular. We'll need to spend lots of time replacing AngularJS with React or Angular (we haven't decided yet), so that decision didn't really pan out.

On the server, though, I couldn't be happier with Java/Jakarta EE and PostgreSQL.
The "running WASM on the server" use case is pretty fun and applies to whenever you want to execute untrusted user code and limit its capabilities / resources, e.g. for plugins. For example, we use it in Seafowl [1] for user-defined functions, so does ScyllaDB [2]. Cloudflare Workers [3] lets you deploy arbitrary WASM code at the edge and pay at high granularities just for the amount of time your function spends executing (e.g. 10ms is the limit for the free tier).

In addition, you can limit the amount of instructions [4] a certain subroutine is allowed to use up before halting.

Also, WASM subroutines can only call out to functions (including system calls) that you allow them to (they're sandboxed otherwise). By default, they can't open files / print to stdout, unless the module can import the relevant functions (which WASI [5] provides).

Cloth masks are effective against a virus with a droplet based spread, like the flu. When an infected person sneezes or coughs, cloth face masks can contain those droplets as they spray out.

With an airborne virus you have to be able to filter the air people are breathing and a cloth face mask that isn't even fitted tightly to the face just cannot do that. This is why you need an n95 mask or better fitted tightly enough to your face to create an air seal.

For example, the Measles also has an airborne spread and the OSHA requirements for medical professionals mandate gloves, eye and face protection, and respiratory protection.

Ask HN: Managing a shared music library from several streaming services?
I currently listen to music from many different sources. In addition to my local files, I also regularly use several streaming services, as well as YouTube, Bandcamp and so on.

Currently, each of these has an entirely different library with different favorites, playlists, etc, which makes it a little bit difficult to manage everything. I use iTunes for my local files, then Spotify has its own library of "liked" files, YouTube has its own playlists, SoundCloud has its own, and so on.

I would love for there to be some kind of simple app that lets me build a music library that incorporates all of these sources. I'm envisioning something kind of iTunes or Winamp-esque, except instead of the elements having to be files, they'd instead just be tokens that could point to a local file, or a remote HTTP URL, or a spotify: URI or a YouTube video or whatever. I would be able to put some kind of basic metadata on each one and organize things into artists, albums, and so on, as well as make playlists.

Does something exist that can do this? I feel like this could be a pretty simple web app, particularly if someone is willing to use e.g. FTP or Dropbox instead of a local file.
Makes sense. My mind immediately went to one of those webpage snippet screen controllers, but that won't work for you.

I struggle as well with this, especially since my dad is blind which makes it even harder to use the computer (even with screen reading software).
If you turn on minor versions there is a publish function, which is close enough to a release.
If you're really worried about lighting, erect a lightning rod. It'll find the best, highest path to ground (almost always), so provide one.

Lightning can do odd things. I had a 500m, underground conduit holding 25 pairs of twisted pair copper that came up and terminated beside my desk. The other end was in another building and there was various equipment connected through this data cable. Grounded at both ends (and some folks at this point know the rest of the story).

Lightning struck a hickory tree near the cable route, about halfway. Not enough to kill it but tore a nice strip of bark off all the way down. The ground surge from that induced current in the cable and my pipe coming out of the floor vomited out a small quantity of vaporized copper and the remnants of the teflon plenum insulation it had been covered in. Like a black powder cannon. Stippled the ceiling with an interesting pattern. A couple of the connected bits were not fried, more things were.

The other end had "a weird noise" I was told. it was 50ft higher in elevation than my side so I assume that air pressure acted as a cap on that end and they just heard air intake past the wire from their side.
I don’t see why these things must be as interconnected as you’re question suggests.

If you have a relatively constant outflow of breath, measurably but not drastically affected by exercise, the CICO conception could still account for the net difference in body mass.
My recollection is that the TS license simply has protection against using the TS code to compete with TS, ala Amazon RDS.

While some people on HN feel that this is an impurity they can’t live with, I personally think it’s a small price to pay to enable development of TS to continue. In my opinion, claiming that it’s closed source is somewhat dogmatic. Many open source licenses have some kind of restrictions on use; the GPL comes to mind.

PayPal shuts account of parents’ group that campaigned to keep schools open
There's many opportunities to go through one of these institutions - you could do undergrad there, grad school, or one of multiple post docs. There's lots of people that go state school -> ivy/prestige -> state school and end up professors. Or state school -> state school -> ivy/prestige. Or state school -> state school -> state school -> ivy/prestige. If you work really hard, chances are you end up somewhere prestigious eventually. Probably hard to avoid.

I was also going to say that there are plenty of less prestigious schools that graduate a ton of professors, like UC Berkeley, but it turns out it's on this list hah.

C++'s standard library optional type is a tagged union implemented from scratch, with a dizzying array of template metaprogramming to meet the standard's requirements- see e.g. Microsoft's here: https://github.com/microsoft/STL/blob/main/stl/inc/optional#.... This isn't a criticism of the team behind this code, it's just what it takes to do this in C++.

Rust gets most of that functionality from the language instead, in a much cleaner way. Sum types are built in, value categories and move semantics are handled automatically, there is little-to-no metaprogramming, and most of the API is just simple convenience combinators with obvious implementations: https://github.com/rust-lang/rust/blob/master/library/core/s...

If nothing else, this is a clear counterexample to the claim that "Option and Result types are as easily coded in C++."

> Code has generally not suffered from being public.

I spent 10 years suffering under a ruby app where literally every interface had to be considered public because someone might have gone code surfing and decided to be clever, so literally nothing was a simple code refactoring of private interfaces that nobody should touch.

I don't understand what kinds of software people who make this argument write, but I assume it has to be something like web services where the http routing layer is the actual public interface definition and so you're benefiting from strong encapsulation at that layer. Yes, in that case the language doesn't need strong encapsulation because your external framework already provides it for you.
Interesting. And the logical second conclusion is that this is an evolutionarily costly process, otherwise it would be common across our muscles. Maybe the muscle has a higher risk of injury, degeneration, cancer than othe muscles...?

I don’t know why this is a problem or even surprising. There are few academic positions. Getting in and making it through the top schools is competitive and difficult. So why wouldn’t the best and brightest and most motivated and best networked beat everyone else out?

I’ve been to every kind of level of school (public, private, non-elite, elite). Whenever I’ve had someone from an elite background teaching at a non-elite place has made me feel better about the education I received, and was grateful for it! Relatedly, the expectations in the elite environments were substantially higher, which ended up producing better work from myself because of my peers, culture, and pressure than when I was lacking those in non-elite environments… despite the fact that I’m the same person.

I hate this trend perusing equality by lowering to the common denominator. That’s how you lose competitive edge in the world and end up with a mushy disinterested public. Talent is non-uniformly distributed… we should encourage and have ample mechanisms for the cream to rise to the top regardless of background. Finding ways to identify and prop up talent is what’s culturally lacking. I’ve seen it first hand countless times, and it’s saddened me each time because it’s so wasteful for society and the individuals. We need access to more elite institutions not less!

There’s a good history supporting that logic but I wonder if there were other trade offs: a couple of the comments around this mentioned better memory compression and some optimization work which made me wonder whether they might have been able to make zeroing faster than a pattern, especially if they’re going to have some generation of Apple Silicon add hardware support.
I’m not sure it’s just that. Explosives availability isn’t much different (I think), and yet I don’t remember European police bombing a city quarter.
> That's the main point - much of the mold problem can be attributed to vapor barriers;

Indeed, if I lived in a cold climate, I'd much rather have a vapor permeable but continuously sealed and insulated wall assembly than a vapor barrier.

> So if we wanted to build mold-resistant houses that were designed to idle at 50 or 60 degrees, we certainly could

Totally. Wood framing, plywood sheathing, and drywall's paper backing are prone to mold when exposed to condensation, but those are the most economical materials we have for building. Keeping condensation off those materials at low temps is challenging, and most easily accomplished by heating them along with the space.

OTOH concrete (i.e ICF) is pretty impervious to condensation, although it has other major issues with that make it not ideal for most house walls.
