I still use the Eclipse IDE on a daily basis for Java development. I like it a lot better than the alternatives. A lot of people seem to prefer IntelliJ's expensive bloatware, but that just doesn't do it for me.

I will repeat my usual complaint: I wish the Eclipse Foundation would invest more into making the IDE better, and I wish they would make it easier for people to contribute to it.
Cumulative funding required for demonstration commercial fusion reactor

Was compelling. Belief we're prepared to invest seems lacking.

I think achieving multi second "stable" plasma conditions has been amazing. But, I think that's a cigarette lighter held next to petrified wood (to use an atomic bomb era analogy) away from ignition as a useful energy over time equation.

We're also somewhat behind "what's embrittlement" or "what's xenon poisoning" problems. Things which don't emerge until a few months in your life of run-time. Again, from early fission reactor design, these things can sink a project.

Or, unexpected fission or other nasty behaviours. Things which make it hard to get inside the structure to fix it. The unknown unknowns in this feel huge. But, linear energy in, energy out, and the approach to viable ignition temperature. That's science and engineering at its best.

Fusors tapped out. "Mr fusion" isn't happening.
I think D language fits your very descriptions.

You have GC by default that's Python like and intuitive programming constructs. Since for the most part D compilation is much faster than C++ and Rust compilation as long as you stick to the core non-CTFE. Heck you can use D as a compiled scripting language with REPL using rdmd [1].

Then if you want to go gung-ho, you can use the other advance features like D's excellent template meta programming, CTFE, bit banging in-line assembly, etc. D has so many advanced features that can be explored later on, even modern C++ is playing catch up with D in every releases. Nowadays D compiler also support C natively [2] and GDC compiler is included inside the venerable GCC eco-system.

There are university that teach software development and engineering class with D due to its managed, on-demand and gradual complexity, not like "in your face" complexity of the big kahuna programming language like C++ and Rust [3]. Like other compiled languages you can build real-time system even firmware device drivers in D unlike Python.

The Flexipede Revisited
Reminds me of OpenMW
> but I think a big part of the issue is that there really aren't great cross-platform options out there and it's hard to keep a consistent UX across platforms if you're reimplementing things for each OS

All that's needed is taking TextAdept or KDevelop or Kate (these are all cross-platform already) or some such editor code-base as a starting point and (A) bringing in VSCode's NodeJS-based extension host and (B) implementing out VSCode's surface extension APIs against that native backing mature editor code-base. Voila, all the great VSX extensions out there are salvaged and ready to use, with no more Electron or MS dependency.

Quite icky and boilerplatey though, not as sexy as starting yet-another-whole-new-editor from scratch... plus the whole latent "ever-having-to-keep-catching-up-to MS VSCode" responsibility ... no wonder no one's on it. Neither am I.

VSCode's extension APIs' restrictions wrt GUI extensibility are a god-send to any theoretical alternative implementors of those APIs. It's just that there aren't any =)
I rather dislike that weird side ribbon thing. Some time ago I thought I'd try and build a version without it, but that wasn't as easy as I would have liked. Maybe I'll give it another go.
Indeed. The day that advertising is integrated into LLMs so they only promote sponsored lemonade we'll have to make the LLMs take the lemons back! Get mad! We don't want their damn lemons!
To understand rollbacks it's better to assume the user has itself borked something rather than the system. You don't necessarily rollback to previous package versions, just to the last state everything was working.

Sure you can fix whatever you did wrong, but that might imply quite a few things and take time. If you go to the snapshot prior to your changes, it takes a lot less time (just a reboot), less guess work, and you can continue working from a blank slate.
I doubt it, because the cognate to English drop, German Tropfen is Yiddish tropn https://en.wiktionary.org/wiki/%D7%98%D7%A8%D7%90%D6%B8%D7%A... and the cognate to English dreep, German triefen is Yiddish trifn https://en.wiktionary.org/wiki/%D7%98%D7%A8%D7%99%D7%A4%D6%B... so I would expect a cognate to English drip to have an initial "t" as well.

Also, https://www.cs.uky.edu/~raphael/yiddish/dictionary.cgi says that "dripe" means "defecate (taboo)".
I agree with everything you say about rooftop solar. If you have a suitably unshaved roof, and you are in a reasonably sunny climate, the current economic math works. And as energy costs go up, and capital costs come down it works better all the time.

That said, we still need a grid to distribute electricity to places that consume more energy than roof space. Think apartment blocks, factories etc. And yes, a huge chunk of that load can still be supplied by grid-scale solar and wind etc.

Even with large-scale storage (another fruitful place to spent investment money) there's going to need to be peak-generation.

However you look at it, I don't think fusion will be the answer. Since fusion was first proposed and the landscape of requirements have shifted. By the time it's practical, it'll be solving a problem we dont have.

The science may lead to a working reactor. But no one will build it at scale because it simply won't solve the problem well have then.
The design is very clever: since it's based on CMAC, we can use AES-CBC to derive keys where lower level primitives are not available.

In AES-CBC terms, the algorithm can be described as:

1. L = AES-CBC-256ₖ(iv = 0¹²⁸, plaintext = 0¹²⁸)[:16]
2. If MSB₁(L) = 0, then K1 = L << 1;
Else K1 = (L << 1) ⊕ 0¹²⁰10000111
3. M1 = 0x00 || 0x01 || X || 0x00 || N[:12]
4. M2 = 0x00 || 0x02 || X || 0x00 || N[:12]
5. Kₓ = AES-CBC-256ₖ(iv = K1, plaintext = M1)[:16] || AES-CBC-256ₖ(iv = K1, plaintext = M2)[:16]
6. Nₓ = N[12:]

Where AES-CBC-256 returns the first 128-bit block of the ciphertext, discarding the padded block. (Thus, if you can't turn off padding, it costs three additional AES calls with the same key compared to a lower level implementation — not bad). After deriving a key, use it with the standard AES-GCM.

Here's my JS implementation based on WebCrypto API, which uses this fact: https://github.com/dchest/xaes

It accepts a proper CryptoKey intended for AES-CBC, supporting all CryptoKey features, e.g. storing it in IndexedDB with "extractable" bit set to false.

Great job, Filippo!

I'm continuously amazed by these kinds of comments. I love Eclipse for Java, it's easily the best IDE I've ever used. There is no struggling.
Mainly jet fuel. Cars and trucks will do just fine on batteries.

The point with carbon capture is that the captured carbon still comes from fossil fuels. You burn it, you capture it, make fuel, and then you burn it again. So, it's slightly less worse than burning it only once but 100% of it still ends up in the atmosphere.

Synthetic fuels made with biomass are more sustainable but only if the biomass is produced sustainably. Which it often isn't. Dumping a lot of CO2 in the air to produce corn and then turn it into ethanol would be the classic example here of something a lot of countries do at scale that isn't really all that green.
GPT-4 offered a marginal improvement over the capability of GPT-3. Depending on how you measure it, it would be hard to call it an exponential improvement. Let's say 30% just to put a number on things. A significant improvement.

GPT-3 cost 4.6 million dollars to train. According to a cursory Google search, GPT-4 cost 100 million dollars to train, about 50x as much. Is a 0.3x improvement worth 50x the cost?

That doesn't even touch on the costs of inference. Millions of queries a day requiring heavy duty compute infrastructure. How much capital are we going to waste on the next marginal improvement? Perhaps Microsoft will "only" need another 30% increase in their carbon emissions this year to sustain the growth.
This is the most hilarious "meet cute" I've ever read.
I would recommend to flash an Android device with LineageOS and to use it in a degoogled manner, with F-Droid alternative apps [2].

They have a nice list of compatible devices where you can search for upstream support [1] and really nice step by step instructions that explain how to flash the device.

I'd personally recommend to get a used Fairphone (e.g. 3/3 plus/4) because they have decent support and are repairable.

If it must be a tablet, I'd recommend to go for a Galaxy Tab because they are pretty well supported by LineageOS.

If you want a mobile Linux device, there's lots of better and more repairable alternatives when you look in the convertible laptop market.

I was hoping the article was about his Apple II game

https://archive.org/details/wozaday_Serpentine
It was a 63kB assembly project that compiled down to 384 bytes. However, that project handled phase-locked control of a power dimmer, logged up to 2 days of power-factor stats information into an eeprom, integrated clock timers, and several user inputs.

It was the smallest, and most bizarre interleaved task-structure I'd seen fit into a $0.17 micro-controller. I kind of admired that the code itself formed the delays for other areas of the multiple tasks, and essentially achieved near perfect resource utilization for actual work.

Never saw anything that efficient again for several decades. =3
> apply proper judgement
This court has gone a long way to say that vibes aren’t a sufficient level of clarity anymore, so it’s only fair that this can work against the court’s allocation of power as much as it has worked for it.
I think there’s some possibly good investment advice to extract here, if you’re able and willing to invest in fusion startups: based on the need to compete with renewables alone, commercial success implies that highly complex reactors simply may not have a market based on construction cost, even if they do generate power.

Of the fusion startups mentioned in the article, I’d say that makes Zap Energy the one worth gambling on (if you’re a gambler that is), as its success apparently depends on exploiting a fluid dynamics effect which was not well known in the past (“shear flow”). If this sufficiently solves the confinement problem, the resulting device looks ludicrously simple in comparison to contemporaries.

Of course it may not work at all, I sure don’t know if it will; but if you had to invest in one of these, that seems like the one where successful power generation actually creates a marketable product.
That's why for every very high value use case (see chii sibling post) you keep some low value use cases running that don't really require high energy concentration fuel. Burn shrubs, waste (e.g. bioplastics), whatever for heat and stationary power and capture that CO2. Low concentration fuels are well available in renewable form and will be forever. Bottleneck solved, at least as long as you don't imagine you could keep up fossil age consumption rates with synthfuels (you can't). Leave those many millions of tons of air to processes we already run on them anyways.

You are right (also with that last paragraph), direct air capture is usually a scam. I might be willing to grant a weak exception to projects that put serial self-containedness front and center, e.g. terraform industries (not to be confused with terraform labs...) would certainly be overwhelmed if they tried to tailor a capturing biomass plant to the local situation with each installation. But even they should better spell out in their advertising "optional, could be substituted with:" for the DAC.
Thin boned and uncoordinated bodies can do well in road cycling and distance running. If you're obsessive enough to execute the right workouts every day then you can get pretty good, although only a tiny number of people make a living from those sports.

Can Congress grant rights? No, because persons have natural rights, inalienable rights; and such enumeration of the rights of persons occurs only in the Declaration, which - along with the Articles of Confederation - frames the intent, spirit, and letter of the Constitution ; which itself very specifically limits the powers of the government and affords a process of amendment wit quorum for changes to such limits of the government in law.

Congress may not delegate right-granting privileges because the legislature hasn't right-granting privileges itself.

The Constitution is very clear that there are to be separate branches; each with limited privileges and immunities, and none with the total immunity of a Tyrant king.

A system of courts to hear offenses per the law determined by the federal and state legislatures with a Federal Constitutional Supremacy Clause, a small federal government, a federal minarchy, and a state divorce from British case law precedent but not common law or Natural Rights.

And so the Constitution limits the powers of each branch of government, and to amend the Constitution requires an amendment.

Why shouldn't we all filibuster court nominations?

Without an independent prosecutor,
Can the - e.g. foreign-installed or otherwise fraudulent - executive obstruct DOJ investigations of themselves that conclude prior to the end of their term by terminating a nominated and confirmed director of an executive DOJ department, install justices with with his signature, and then pardon themselves and their associates?

The Court can or will only hear matters of law. Congress can impune and impeach but they're not trained as prosecutors either; so which competent court will hear such charges? Did any escape charges for war crimes, tortre without due process, terror and fear? Whose former counsel on the court now.

What delegations of power, duties, and immunities can occur without constitutional amendment?

Who's acting president today? Where's your birth certificate? You're not even American.

What amendments could we have?

1. You cannot pardon yourself, even as President. Presidents are not granted total immunity (as was recently claimed before the court), they are granted limited Privileges and Immunities.

2. Term limits for legislators, judges, and what about distinguished public/civil servants who pick expensive fights for the rest of us to fight and pay for? You sold us to the banks. Term limits all around.

3. Your plan must specify investment success and failure criteria. (Plan: policy, legislative bill, program, schedule,)

Can Congress just delegate privileges - for example, un-equal right-granting privileges - without an Amendment, because there is to be a system of lower courts?
I don't know, spending a trillion dollars on housing development would probably solve a lot of problems.

Not really. Do you think "Unfair" has an objective definition? Just saying something is unfair won't make it automatically or objectively unfair. Non competes are not deceptive.

It may be covered but the point it is not logically implied by the text you quoted.

Compare that with the objectivity of this (still contains a lot subjectivity):

There's a saying, "Only commit one crime at a time". Knowing when to cheat is a fairly high-risk but pro move.
But wouldn't that mean it's black holes all the way down? If in our universe, another universe is inside every black hole, then aren't those universes quite small due to their total mass being the same as the black holes'? The mass of black holes can be quite modest. Then the universes inside those universes' black holes would be even smaller, and so on.

Also, it's my understanding that black holes shrink over the time, so they aren't expanding and certainly not at increasing rates like our universe is. The ones in the center of galaxies "gobble" up gas, but most black holes aren't at the centers of galaxies.

Things to Do When Your Pet Goes Missing
> small and medium organizations abandon technology like Kubernetes

K8s is a complex tech that requires multidisciplinary experience that small and medium orgs cannot afford. Even if they could, there simply is not enough talent to hire. My own experience shows that k8s makes developers less productive, because running a heavy stack locally is not exactly conducive to fast development cycles. I don't feel empowered, I feel abandoned and left dealing with a steaming pile of shite that used to be the responsibility of a DBA, Ops, and security. Unfortunately, the trend for hiring "full stack developers" who can do frontend, backend, infra, and DBA aka. "I want a whole team for the price of a junior dev" is not going away.
So here is the evidence: We know the big bang fulfilled the math criteria of being a black hole. We also know how black holes work from the outside from observations today. The simplest theory explaining both of those is that the math for the inside of the black hole is wrong, while it is right for the outside, and that we observe in our own universe/black hole is what really happens inside. Any other explanation simply has less evidence behind it.

Speculating that there is some strange singularity there is just as much sci fi as speculating that there isn't and that what we observe from the big bang is the normal state. Any theory saying that the black hole has a singularity inside would need to explain why the universe isn't a singularity, otherwise its provably wrong, since we know the universe isn't a singularity.

The only evidence against the universe and the big bang being a black hole is that it lacks a singularity, everything else adds up to it being a black hole. Ignoring that evidence is more unscientific imo. Also saying that the universe expands due to "dark eneregy" is also baseless sci-fi in that case.

Anyway, if black holes do become big bangs like that then it could be testable by looking at distributions after a big bang etc and compare that with some different ways of calculating black holes sucking up mass in different scenarios to see if it is reasonable. Science starts with speculating about stuff, speculation is not non-science. At least this is more testable than stuff like dark energy.

Edit: I've also studied all the math and physics in college for the testable parts of GR, I haven't studied string theory, at that point I no longer felt the physics made sense, I don't think it is wrong for me to hold alternative theories to the untested ones.
The problem with devops was that companies thought they could get away with training a dev to run a server farm (or training a sysadmin to code)... while it might have worked for some companies, it just smacked of being cheap everywhere else.

When comparing VS Code with Atom, vim, Emacs, others, an underappreciated fact is that extensions just work, and are very easy to install and configure, which has much to do with its model. Atom was unusable for me, because, as you installed extensions, something always broke.

This is also similar to the old Firefox vs Chrome. The former was great for power users, but it crashed a lot and Firefox installs of regular people were riddled with insecure extensions that broke the browser and that couldn't even be un-installed.

VS Code does have flaws, but having limited extensions is not one of them, IMO.

> The point with carbon capture is that the captured carbon still comes from fossil fuels

That's not a property of carbon capture, it's a property of the fuel coming in on the other side of the (stationary) process. We certainly won't be seeing carbon capture of jet fuel any time soon, so the fuel preceeding the capture will definitely not be the one produced. Think waste incineration, think bioplastics (don't waste that precious energy on some pointless biodegradation!), think single use paper, think moving the part of the natural carbon cycle that happens in bushfires and the like into a controlled environment.
