What I principally remember from William Shirer's Decline and Fall of the Third Reich was that Hitler would have been crushed if the war had started with the invasion of the Sudetenland.

Perhaps Russia sees the Ukraine through a similar lens; addressing problems there become more costly with time.

It is a shame that accommodation could not be found, and war averted.

Ask HN: Is it possible to become a good programmer by one's own?
I am talking about self taught people. And by really good I imply good knowledge of CS fundamentals so that when they write code it looks and runs elegantly. Performance is thought about and also readability. We know CS is about computational problem solving not just about programming.

Most guides out there say do this course or learn this language or may be do some web development and you are a programmer. I know it works to a certain extent but doesn't achieve anything beyond a certain threshold.

Is it possible for someone to self study CS from available materials like good books, public course contents? To such an extent that they have solid grounding in CS fundamentals, learns programming as a tool and become good at it gradually and when needed can venture into a sub-domain and learn about it using the skills already obtained previously to solve problems computationally.

Has anyone here done that? Can you share your journey? Or are there any documented blogs or something?

No offence to "web developers", but I am not looking for advice like learn this framework, this is hot. I want transferrable skills.
Get a chain lock, wrap it around either the seat pole or part of the frame for storage/transport. There's basically nothing that can go wrong, and there's chain locks in a wide variety of costs/security.

Permacomputing: A holistic approach to computing and sustainability (2022)
I am very sorry to hear about your situation, it sounds significantly more stressful and awful than mine. I hope your family gets through this successfully. I cannot even imagine how to deal with having someone close to you being directly in the action zone there. My dad is in mainland Russia, but given recent laws that Russia passed in regards to "fake news" and protestors, we seriously were concerned about our calls being tapped. And not in a "oh man, that's not cool for someone to tap our communications", but more like "15 years of russian prison and/or much worse consequences feel a bit too close right now" type of way.

> she can make an international call to us.

One question about this, if you don't mind. What's the best way to do place international calls there in terms of convenience/cost/quality and just as an overall package? My mind jumped first to Google Voice, because that's something I've used with success before. But I don't have much of an idea about alternatives, so I wouldn't know if there was something much better suited for the purpose.
-Ukraine had nuclear weapons, and gave them up in 1994 negotiations with Bill Clinton.

-A member of the Ukrainian parliament contributed to the "Steele Dossier" that was used to slander Donald Trump.

-Burisma and Hunter Biden.

-Ukrainian membership in the E.U. will do great economic damage to Russia (although what is happening now might be worse).

This is my understanding of what the "scraps of paper" for denuclearization covered. I don't think NATO membership was addressed. Is there another treaty or commitment you're referring to?

Inflation.

Everybody talks about how increasing the money supply means increased demand, which drives prices up. But nobody explains how does this *practically* happen. Prices don't go up on their own, it's the retailers who increase them at some point. So if the retailers' perception of the reality is not accurate (Suppose for example that money was printed "secretly", or that the increase in demand wasn't very apparent) prices won't magically go up, no?

There is a common knowledge component in all those equations that's missing and nobody talks about it. Maybe it's too obvious that I'm overlooking it.
For the Northeast US (the largest heating oil market in the world), there isn't any kind of heat pump isn't going to work with existing forced hot water heating systems which is by far the most common type of install.

The heat pumps don't put out enough volume of water at a hot enough temperature (heat pumps at maybe 125F vs 185F for oil/gas boiler). Most radiators / baseboards will radiate about 650BTU/hr per linear foot at 185F and are sized based on the heat loss calculations for the room/house and the ASHRAE design temps for your location. So if a room needs 6500 BTU/hr at 25F outside to maintain 70F inside, then you'll need 10' of baseboard. If you start feeding 125F water instead of 185F water, then you'll get significantly less heat out of the rads/baseboard and you won't reach the design temps indoors unless it's much warmer out.

Generally heat pumps (ground or air source) are forced hot air (since you only need to raise the air temp by a few degrees as long as you have enough CFM of air flowing), or radiant slab where you only need 75-80F water or the slab cracks and/or is uncomfortably hot. A combination of both also works as a radiant floor doesn't help with cooling in the summer.

If you've got an existing forced air heating system, or are building a new house with forced air then either a GSHP or some of the newer air source heat pumps are a fantastic idea (despite the somewhat premium price vs a traditional oil/gas/propane boiler).

Note that for GSHP it'll probably cost you upwards of $15K for the artesian well alone, but maybe you need one anyway (or already have one) if you're not on city-water in which case the only additional cost would be a variable speed pump vs a fixed speed one (assuming that the well is deep enough and has a high enough flow rate to provide enough "tons" of heating/cooling). Finally, not every city or town will give you a permit to drill a 600+' well (assuming the geology supports either an open or closed loop system).

... and you still need a heat source for domestic hot water, probably an on-demand natural gas/propane unit or an electrically heated hot water tank, although the GSHPs have a "de-superheater" feature that lets excess heat be diverted into the h/w tank during the summer/shoulder seasons, but generally not the winter.

... and the GSHP usually needs a backup heater (often resistive electric coils, but a smart design will use a hydronic coil on a zone on a condensing combi-boiler if you have one for hot water). The air source heat pumps definitely need a backup heater as they periodically run backwards to defrost the coils in the winter to prevent ice buildup in the condenser.

Well, there was an Open Letter on change.org which was signed by over 1M people, its author was shortly arrested. Also, there were more than dozens open letters from various communites (IT included, 33K signatures).
The only impact those open letters had is that now there is a new law in Russia which prohibits (up to 3 years in prison) any public calls to stop Russian army from doing what its are doing. This new law can (and will, in individual cases) be interpreted as "signing the open letter == call to stop a XXX == law violation".

The anti-vaccine movement developed as soon as vaccines forest existed, and it developed independently on at least 3 continents. Even if you could snap your fingers and make social media disappear, people would still at various times and places refuse vaccination.

Also your assertion that free will doesn’t exist is highly suspect. Either you’re coming from a place of collectivist ideology and work backwards or your reading about Libet’s button press studies. I’ll assume the latter, since is more interesting. Trying to pick apart awareness of intention to move, RP (readiness potential) as measured by eeg or fmri, and the movement in less than 300 ms using a clock the participant has to read is highly fraught. The setup could easily be wrong. Other researchers trying different approaches to measuring the awareness of the decision point have gotten the opposite results. There’s also absolutely no consensus among researchers on this topic. If you truly believe as you say that science is the key to progress, you must admit that the science of free will is very much unsettled. And we must also consider that cognitive neuroscience research has had a lot of embarrassing missteps, e.g. replication issues.

You may choose to believe people have no free will, but I feel agency in my actions so it’s real enough to me. One must also concede that there have existed totalitarian systems in living memory that predetermine all human actions that should happen in the system, and yet some people still rebel. There must be something there.
I'm probably missing something obvious, but in what way is the actual shock wave generated? How is something as large as a galactic cluster coherent enough in any way other than gravitational attraction enough to generate a cluster wide shock wave? Is it just the gas clouds colliding at extreme speeds as the clusters come in at each other at 'relatively' high speeds?
Rather, I would bet that his stance is that if you are motivated by something else than money, you shouldn't go through VC-backed funds to build your business, because sooner or later someone will squeeze as much money as possible out of your business.

Trying to exit one of those windowless programs on Windows at least, can be rather hidden functionality, and may involve resorting to the task manager. On mac OS, by default it's in the dock if it's open, it's cycled through with command-tab, and once you bring it to the front, you have the menu bar as a uniform interface for interacting with windowless apps. I don't even use mac OS but on this aspect it does seem more consistent.

Before I read "custom phone app", I was imagining a mysterious physical red button somewhere up a telephone pole you had to climb, which through some abuse-of-job-privileges-or-connections you had wired directly into the telephony wires leading into your house.

I wish you hadn't clarified.
This was the first thing I learned when I started using a Mac in 2007. I took some years off and ran Windows from 2012 to 2021 and never forgot this aspect of Mac.

Groundbreaking!
That's optimistic. The 3 GSHP systems and one ASHP I've been involved with have been in the $50K+ range although all but one were a new build and includes the AC ductwork in the house (the other was forced hot water and involved retrofitting ducts). Tack on another $15K+ or more for the drilled well & pump (obv. not needed with ASHP).

Sadly, it's kind of a boutique market and people who want these systems are often willing to pay quite a bit for them.

As for the rebates, most of the installers seem to think that belongs to them, so if they're quoting $50K, that's after the rebate, despite the fact that the equipment (e.g. a 3.5 ton water furnace) isn't really that much more expensive than a higher end high-efficiency gas boiler (e.g. $5-7K ish).

Do you perform any file management operations from Spotlight’s search UI outside of the Finder?

Return has a different function in different apps with different paradigms, but the Finder has the longer lineage with the longest set of principles baked into it, treaded upon somewhat with the Mac OS X transition but at least consistent with the compromises that were made in that transition so when you hit Return in the Finder you get a file management function (renaming) because you’re working within a File Manager.

> Everybody talks about how increasing the money supply means increased demand, which drives prices up. But nobody explains how does this practically happen.

Money supply isn't the only thing that does it, but when demand goes up sales go up, the additional production to keep pace with the sales has higher per-unit cost (because marginal costs increase), and everyone in the supply chain raises prices as a result. (That's simplified, a lot of price changes are anticipatory based on predictive singles, but that's the basic process that ultimately acts to align prices even if the anticipatory pricing misses movements.)
> Ethereum [..] is getting dangerously close to this point.

Not any more. Ethereum (PoW) sync time and storage size have improved a lot since you measured them. (I've worked on algorithms to improve both these areas so I know them well.)

Since we're talking about scaling issues, rather than what's readily available in the well known implementations, I'll describe the best implementations that I know about.

Sync time: Syncing a full history archive node has been done in less than 1 day. It's reduced a lot from the multi-month syncs before, even though the chain is larger now. Syncing just the state for recent history is commonly done in under 6 hours. Both can be reduced further.

Storage size: The entire full history archive state fits in about 400 GiB. With all blocks but just recent history (i.e. a typical node) it's about 200 GiB, and when reduced to 1 year of blocks (EIP-4444) the total storage required for an Ethereum node fits into about 100 GiB.

Storage I/O: I don't have hard figures for this, but both the sync algorithms and storage compression techniques reduce IOPS load significantly.

Storage of full history in particular has been hugely improved over the 9-10 TiB required by Geth or OpenEthereum shown at https://etherscan.io/chartsync/chainarchive You can fit a full history archive node on a Raspberry Pi and small consumer SSD now if you want.
