>I'm not sure the traditional Heathkit-style "kit" market exists any more, though.

IDK, I've been gradually working my way through some of the solder-it-yourself "build an XT clone" projects; there the fact you're building it from parts IS a big part of the charm. Nobody would want a slightly quirky DOS machine with less performance than an off-brand graphing calculator without a healthy dose of the IKEA Effect. I suspect a lot of the "build your own amplifier" hobby groups are the same way. (Speakers, apparently there's still money to be saved there if you like DIY offerings)

In a way, it's about turning "thing you buy" into "thing you do" -- you get more hours of entertainment out of a given dollar spent on kit products than a similarly priced finished item would provide.

Yes, 50 years ago, building from kits was about saving on assembly (or for access to products not sold assembled), but there's no reason it can't be a hobby in and of itself and potentially a gateway into more sophisticated electronics experimentation.

I figure a good kit is like the programs in an '80s computer magazine-- it will do what it said, but now you have something that you can grasp and pull apart more readily than commercial product. How many of us got into programming that way?

The other drawback to getting things pre-assembled is that bodge issues are going to be harder. The last PCB I ordered (a custom-designed memory board for that XT clone) needed some, and if you're still looking at a bare PCB, maybe with through-hole sockets mounted, you can pretty easily do any cuts and tacked down wires you need. I'd be a lot warier if I had to try to pick apart pre-soldered SMD components.
No, but if you write a paper arguing this with a catchy title (why not "Soul in Captivity: Exploring Sentience in GPT-3") and publish it on a preprint server, there is a nonzero chance of some (non-scientific) publication writing about it, and once that snowball rolls... :')
It’s like, people with scientistic views, praising objectivity, claiming that consciousness doesn’t exist, come out with conclusions like “a system understands Chinese.” I’m afraid I find this so ludicrous that I can’t continue the discussion on a civil level.
Once hydrogen-powered aircraft move into a route, kerosene craft will be wholly unable to compete, and will be pushed out to less profitable routes.

The hydrogen will be electrolysed from water and liquified right at the airport, from power delivered by HVDC lines.

I expect the LH2 tankage will be in under-wing nacelles alongside the engines. Probably existing airframes can be retrofitted.
The whole article is basically about the question if solar power will continue to drop in price and if power-to-gas tech can have a similar drop in price. If those two are true then power-to-gas will become economical viable to the point where people could use it to store power produced in the summer to be burned for baseload/winter. It will also mean that pure hydrogen and pure oxygen, in compressed storage, will be is expected to reach a point where they are too cheap the meter.

Of course we are not there now. 2030 maybe? 2040?
Ego is not "you". Ego is just a group of distinct cognitive mechanisms working in unison which is perceived as a whole. It is absolutely unrelated to free will and sentience.
I'll do one better, just don't marry. Pre-nups are routinely thrown out by divorce courts.

Unless the guy is extremely poor and marrying a high net-worth woman, there is just no point in marrying, you gain absolutely nothing (except for pithy tax benefits in some cases).
I haven't used KDE since the Plasma transition, when it got buggy, and according to most users' reports, stayed buggy for quite a while.

Allegedly it's much better now, but this string of 'we fixed all the bugs this time - promise!' posts I'm still having my reservations.
more diverse, maybe.
You mean you hate that they have a business model?

Seems fairly healthy to me. Free to start out and you'll have to pay so you can use more.
That is largely an unverified urban legend. Every "article" about it cribs from the same StackExchange thread, which has one person say that that worked for their mac. I've owned multiple USB-C macbooks for years (in case you're wondering why, mostly due to laptop churn at work.) and none of them had any issues charging on either side.

The funny thing is, the last time I ran into this was at work, when a colleague mentioned they only charge on the left because of this issue. I pointed out that the original post said you should charge on the right and they were left pretty red faced after that. Clearly, they didn't have any issues with charging on either side.

If you need any more evidence, just consider the fact that the macbooks that only have ports on one side have them only on the gasp left!

Ask HN: Solar PV vs. Thermoelectric
One of the main complaints against Solar Photovoltaic systems is the limited availability of sunlight due to time of day constraints or latitudinal constraints. Solid-state thermoelectric devices operating on the Seebeck effect only require a temperature gradient to produce a voltage.

If we combined a thermoelectric device with surfaces engineered for heat absorption (eg: a black coated surface) and passive radiative cooling (eg: ultra-white coated surface) would we be able to maintain a temperature gradient and break the time-of-day and latitudinal constraints of solar?

1. What are some of the challenges with this approach?
2. What are some ways this could be improved to make it practical?

So draw me a picture then. Let's say I'm off by 3 or 4 orders of magnitude, photosynthesis is .001% efficient or whatever. Show me how you create enough energy, the equivalent of a billion years worth of solar energy shining down on three quarters of the surface of the earth, every 200 years. 2000 years. 200,000 years. Without unfathomable environmental destruction. Or how you reduce the energy consumption of 8 billion people to a point where it is manageable without killing most of them. Give me more than one sentence.
The current price of electricity is determined by the price point of installations that are already built, which has absolutely nothing to do with the price of installations that will be built now and from now on.

Also you need to learn the difference between Capex and Opex.
The problem with an hybrid approach is that it forces you to live close to the office. If I were living in Hamburg and the company I want to work for is located in Munich and requires me to go 1 day/week to the office... Well that's a nogo to begin with.

So hybrid mode limits a lot your pool of potential employers.

For that, you need something more like obfsproxy or some other steganographic tunnel, which of course also requires an endpoint on the other side much like a VPN.

The actual insulation is stupid cheap when you look at the ROI. However, installing in on an existing house is really tricky and you can cause a lot of moisture related damage if you do it in the wrong way.
When he died there were lots of extremely positive and nostalgic comments about him. Are war criminals automatically forgiven when they die? Will Bush also be remembered fondly and for his buffoonery and not the war crimes? That's bleak..
Definitely build strong relationships before you move away. Sacramento (and more broadly the rest of california) is nice b/c it isn't too far from the 'action' and you can go back to SF for conferences/accelerator pitches/etc, but you need to network for quality over quantity. And, honestly, I'm getting older so I care less and less about the latest trends or optimizing for total compensation.
I strongly second the suggestion to explore operating as a non-profit if you continue.

My local incarnation, BARN[0][1] is a financially sustainable nonprofit. However, we wouldn't be sustainable as a for-profit company, certainly not if we had investors chasing a return.

Is it an embedded version though? If you see the start menu, probably not. Because you can easily disable it on windows embedded. And configure a lot of other things, that prevent it from glitching out.
I've used it with my team for a couple of years and I don't really dislike it as long as people don't take it very seriously. It is mainly a tool to reason about what needs to be done. It's interesting when someone gives a 2 and someone gives an 8. Why 2? Why 8? Discussing about a thing makes it clearer what may be complications and things to be aware of.

Honestly I don't care about the number themselves and probably three levels are enough and may well be orange, apple, banana.
I’ve watched too many movies, but this sounds like part of a heist.
But how could you ever really be sure that the device couldn't take an update assuming it must be connected to a network in order to fulfill its function? Hardware is so complex these days it's not really feasible to prove negatives.
That source tarball is autogenerated by github when you make a release and it in no way implies linux compatibility, it is simply a way to download the source code without git.
I think macOS at some point supported file system transactions as well. If you look through the AppleScript docs there used to be references to file system transactions, but it appeared incomplete and undocumented.

Would love to hear more details if anyone is knowledgeable of this arcane history.
You misunderstand, my decomposing body will produce carbon dioxide.

The Sahara desert is a great idea, probably our best bet. And if we can source all the material needed to pave it with panels right from underneath it, all the better. But that's unlikely, and still, that's 2% of the earths surface. Not enough surface area to cover our energy needs, despite what anyone says. If we really have reached peak oil, that is, used half or more of the oil available to us, in 100 years, that took 75% of the earths surface a billion years to produce, paving the Sahara desert won't make a dent. Even using energy from the sun 100 times more efficiently, that's still 50 times less energy than we need, 2% of what's needed, and that doesn't take into account increasing energy needs worldwide.
Changing users' default shell is not the same as forcing it on users. You can chpass(1) and set a different shell.

I'm not too comfortable playing devil's advocate here as Apple really does force shitty changes on users. But this isn't one of those cases.
Good advice, but difficult in practice. Many activities stopped meeting in person during the pandemic and have barely started to resume them. And there are fewer than you would think.

Has anyone had success with this that they can share?
That’s no different from store brands at grocery stores. (And it’s AmazonBasics/Solimo.)
This sound literaly like a subplot of the famous 1984 book by David Lodge Small World: An Academic Romance

In the book professor Robin Dempsey almost become mad by chatting with ELIZA and gradually begin to believe it's sentient to the point of being ridiculous.

PS: Apparently it was also adapted in a British TV serie in 1988, but unfortunately at that time they tended to reuse magnetic band and it's improbable that we can dig a clip out of that. Would have been appropriate an illustration!
> Well, we need to eat more plants. We can get by just fine if we dedicate fewer crops and less water to raising meat.

What? People raise meat animals because animals can make use of non-arable land. It has been this way for millennia. (E.g., raising animals is the only way to survive on mountainous rocky slopes.)

Apparently, your solution to scarcity of arable land is to keep using more and more of it? I know hating on meat is the politically correct position right now, but come on!
Methane’s much higher global warming potential (versus carbon dioxide), implies that there’s a threshold of methane leaks above which the warming would be worse than if you did nothing at all.

What trend makes you think nuclear is going to make a paradigm shift?

I keep reading the same "nuclear is the future", but not only it is not improving its costs, it's getting worse. EDF is just broke, and the french citizens are going to pay for it.
There were "baddies" on every side, but one side was the morally "rightest" - the ones fighting for their freedom and independence (aka North Vietnam, the communists). All the rest were colonial powers trying to force a corrupt puppet state which had nothing positive going for it other than being against the communists. So, motives-wise for war crimes, I'd take "freedom (not individual, for the country and peoples) and independence" over any of the reasons why France, the US or China were there. Still war crimes, still needed to be tried, but nobody did that anyways in that war, so all else being equal the motives "win".
> France was one of the few modern examples of a successful refactor of the culture of an entire society - wholesale out with the old, in with the new - a true 'Year Zero' style revolution, not some sort of disguised compromise with the ancien regime.

That's highly inaccurate. Yes the Revolution started out with those aims but descended into bloody factionalism, then came Napoleon, war and defeat and the Bourbon Restoration.

The secularism of modern France has more immediate roots in the complex politics of the late 19th century.

> you start to not want to be around people or not want to talk to people, you forget what they can offer you.

Right, but u64 is kind of long for something you might want to read over the phone, or enter using DTMF tones.

That's the problem. Not all of them will implement tunneling their own traffic through SOCKS, and there's still other things like DNS that you might also want to go through the tunnel, but can't easily do so. A VPN sits at a lower layer, just looking like a regular network connection, so applications don't need to be aware.
Everyone’s focusing on that because they want to discuss the interesting bit - is it sentient. What you’re pointing out is true, but not really interesting to discuss because everyone already knows that and it’s not that controversial. (For limited values of everyone. Obvi not all readers actually know that.)

I mean, it could be interesting to discuss a more European style of employment where he couldn’t be fired for this, but Mountain View has little chance of joining the EU any time soon so discussing that is of limited use.
Honestly it is sickening that the supposedly mightiest military power in the last decades is incapable of holding its war criminals to account. During WWII generals (like Yamashita) were hanged for war crimes that happened in their area of responsibility (not even under their command and control), so nothing as a consequence for directly ordering a massacre or torture is simply unacceptable.

Edited to add: not only is it incapable of holding its war criminals to account, it has an explicit law to allow itself to invade anyone trying to do that (Hague invasion act). It's not incapable, it's hostilely unwilling.
What is the VPS if I may ask? Is it an EC2 instance..?
25-30 years is a pipe dream. Panels manufactured around 2006 are quite inefficient compared with those today, and our need for electricity isn't really going down either.
> Reducing energy consumption is as important as generating and storing energy.

Only if the efficiency is 100%. In practice it's lower than that, so reducing consumption is better than increasing production.
I have wondered about that too. But when I think about a file system transaction, I immediately think about a file system transaction enlisting in an ambient transaction, together with a database transaction. This would make code much more simple/clean for cases where you must create a file and store metadata on the file inside the database. And on the other hand, some database systems do provide features for storing large file-like blob objects, which give you these transactional features.

So I think it depends on the context and what you wanna use it for. I don't see the transactional features of a file system as useful for actual users that are directly interact with files on their file system. It seems more useful in the context of applications that maintain files and where you likely do not want the user to directly interact with those files.
My favourite writer, Czesław Miłosz, remarked how rich the nature was in Lithuania during 1920ies and 30ies (back then, not much changed there since the middle ages), compared to him living in Berkeley later. He wrote that the instect life was particularly impressive and you could have a wall of your house covered by a scum-like layer of various insects. My grandmother, who lived back then in similar conditions, said the same - there could be so many instects that it looked as if the whole wall was moving.
PhD in the UK is a different level of poverty compared with PhDs in any other “Western” country.

Can you imagine graduating at the top of your class and you living in London or near London on less than 20k pounds a year? You can double or triple that income in other phd programs.

The only advice if one really wants to do a PhD is to sample broadly across different countries and PhD programs and choose one that unlocks future options and also pays living wages.
Private is not always cheaper — the NHS comes to mind as a counter-example, and is cheaper in part because the British government gets to act as a monopsony.

While competition can indeed help illuminate new solutions, competition can also come in the form of different political parties and international comparisons.
Thank you, I do too. I though it was only me.

SSH is very simple and there’s almost nothing a SSH tunnel can’t do.
I doubt that this is an extravert/ intravert divide and am pretty sure it has more to do with the current life situation.

Young, single and living nearby by yourself or in a shared flat without a dedicated room to work in? Not too sure about what to do with free time? Going to the office for socializing and structure is great.

Married, with kids and living in a house on the countryside? Strong social ties and no need to get to know your colleagues? Or traveling around/ having an otherwise fulfilling life outside work? Then, remote is awesome.

I'm rather introverted myself and very happy with hybrid. Meeting colleagues when I feel like socializing and in need of some routine, working remotely when I have other things to do and want the flexibility.
I agree that the article is written in a clumsy way which I found irritating. I don't think that can or should be ascribed to intelligence at all.

The author has created an article which largely hangs together. The elephant in the room is - maybe your maxim is wrong?

yes you're right, my comment was a gross over simplification. The revolution triggered multi-decadal chaos, maybe not resolved until after WW2, perhaps not even until after De Gaulle. However, all revolutions tend to be this way - it is through the oscillating tension that the old order is eventually destroyed or transformed

But the price was probably settled well in advance, so the seller was left taking on market risk, which depending on the way things went, could have been anything between a bad loss or a nice windfall. Less likely the latter, I would expect, since they were forced to sell the cotton in Bombay or cover the cost of transport elsewhere.

I don't claim to know the full causes of the current inflation issues, but inflation can also be caused by a reduction in productivity, not just by an increase in money supply.
In practice, most js engines these days can ‘recognise’ the ‘class’ of these objects (if you create them from scratch in a few places) and the memory representation would end up with a word for the ‘class’ which says that time is at field 0 and price at 1 and volume at 2, and then the data itself. The main reason is to speed up code that reads the fields rather than memory use.

The Chinese government has overt control over any Chinese corporation of consequence. This alone should be enough to disqualify Chinese telecom equipment from critical areas in my opinion. I'd expect the CCP to take similar precautions where feasible.
