> Fulfilling the Lawson criterion for a burning plasma doesn’t yet mean that we can produce useful energy with fusion power plants. The next step toward that goal would be to demonstrate a fusion scheme that produces as much energy as that contained in the laser pulses driving the reaction. In other words, the scheme should have a net gain, G, of 1.

This is what I had always kinda sorta thought, but seeing someone put it in words made me realize that it actually doesn't make sense at all.

If 1 unit of laser energy gets you 0.2 units of fusion, that means you end up with 1.2 units of heat energy total. Okay so 1.2 units of heat just sounds like a crappy heat pump. But given that the heat is so damn hot (meaning ~0 entropy) you could in theory convert it all to electricity and come out ahead.

Unfortunately OP submitted the About page rather than the home page. From https://objective.st:

> Objective-S is possibly the first general purpose programming language. It makes creating well-architected and efficient programs not only straightforward, but easy, fun and fast.

> Yes, this sounds insane, programming languages we call "general purpose" number in at least the hundreds, starting with C, Java, Smalltalk, Ruby, Python etc.

> However, these are actually DSLs for the domain of algorithms, and this architectural mismatch, the fact that we have to use algorithm DSLs for tasks that are not primarily algorithmic in nature lies at the heart of much of the pain we have in software development today.

Being pretty far-left (by American standards, anyway), I feel extremely out of place on this website for reasons that I think are pretty benign in the grand scheme of things. I support programmers unionizing, but the overall vibe of this website is that making a little more money individually is more important. Unions just aren't that radical, though. This site skews towards high earners, but the rest of us programming grunts in the trenches could use the solidarity.
were you looking out into the sea? don’t know if you realize, but without good horizon references you lose sense of scale (relevant: supermoon is now) and you also can’t easily distinguish 3 dimensions. contrails going mostly horizontal can look quite vertical, for example.

As mentioned in the post, LOAD/STOREALL only run in ring 0. Also you can't use it to return to real mode except from code running in ICE address space, which isn't accessible except on the special bond-out chip version.

What you can do with STOREALL - with the F1 prefix - is store a bunch of internal registers to memory and then have an external chip (such as the AT keyboard controller) reset the CPU.

Intel for some unknown reason tried really hard to make it impossible to exit protected mode!

Is anyone proposing without access to an AR-15, or any firearm for the matter, this mentally-troubled yet ignored by all the appropriate authorities youth would not have lashed out violently?

It's not too long ago homemade explosives were a seriously real threat in this nation (and others with much more strict regulations, such as the UK). Mass knife stabbings aren't that uncommon around the world, and driving a vehicle through a crowd remains one of the most effective means of violence readily available.

The point is... the tool isn't the problem it's the person. It's a figurative band-aid to think we can solve mental health issues by taking away objects and ignoring the actual core problem... which is mental health.

Stable, mentally healthy people do not commit these mass violent acts. Full stop.
Once the human became the focus of the computer and internet usage, I think that's when it lost that amazing feeling. When the real identity became central to the majority's experience of the web.

The Eastern Mediterranean was rich and civilised long before and after Rome was a backwater.

I think you're conflating Ron Paul's brand of (populist) libertarianism, with its embrace of everything from abolishing most of the federal departments to returning to the gold standard, with the cyber-specific futurist hacker variety. The EFF and the Mozilla Foundation and other FOSS orgs are still there, but certainly there's been a lot of setbacks. Pirate Parties never caught on in the U.S., unlike in Europe where they're more of a presence for whatever reason.

The decline of pirate politics was underway by the time of the renewed culture wars in the 2010s, and I don't think the rise of social justice or identity politics was the cause of it. Those latter topics just were more popular because, well, they resonated with more people. (Feels like the defeat of SOPA/PIPA was the last time such issues had semi-mainstream appeal.) And more people were online, on social media, because tech went fully mainstream. (I suppose in your view you could claim that tech was a victim of its own success.)

They really don't want you to root your PlayStation, but that's mostly because it allows you to hack offline games. Hacked consoles are usually banned pretty quickly from online services.

One can even omit mentioning the position on the resume, if the total break is less than 6 months. It should be fine.
yea.... its a shame cause i love cooking in my cast-iron wok....

one alternative i use is to heat the oil but not to smoking (also use an oil with a high smoke point) on low heat for a couple mins, swirling around, then dump the heated oil, then cook on a low heat from there... its quite non-stick and it reduces the oil content in the food and hopefully reduces carcinogen risk as well...

another thing is to just use water (plus maybe a small trickle of oil) as a non-stick agent (though its hard to reproduce a lot of recipes this way) for fish/meats and vegetables if you can get away with it

Ask HN: How would one get a list of all veterinarians in the US?
Hi HN,

I have a great idea that will revolutionize veterinarian care, but I would need to get a list of vets in the U.S. who would be willing to get a referral from my website. I get about 10 emails a month that could be monetized with a referral fee, but I need to create a list of vets that are available and willing. How would you go about contacting generating a list of vets in the U.S., and not spamming them with email that they would never read?

but apparently not.

No, no no no no no no. Perhaps this made more sense in 2008, and I was there for the 4chan and the glory days of Usenet and all that magic jazz and in my early twenties, sure, you could have unironically called me a libertarian and been almost right. but not now.

The very premise of the article, taken in today's context, suggests that one should not be a libertarian. Systems thinking, aversion to restriction, and a balking at authority should, if you're using them right and bothering to think, lead one to want less free markets.

FAANG, unrestricted, is far more dangerous and toxic to innovation than any government. Same goes for banks. Same goes for the entire legal profession. If I'm at all familiar with the libertarian ethic, the idea is that you let these things expand organically without fetters. This is Bad with a capital B.

I would faster align a good hacker ethic today with the far left. Like, far, far left. Not democrats, not liberals, definitely not libertarians. Anarchists, in the "headless governance" meaning of the term. Distributed decision making without representatives.

Libertarians, neoconservatives, and all the rest of that "free market, small government" drivel are just handing the keys to the neighborhood burglar. The systems perspective, or rather, my systems perspective on this is that it's to late and the only option is to wait for a total credit collapse. But those free markets got us to the place where k Street has the funds to write their own laws.
> Just because this french document doesn't make a scenario like that doesn't mean its not possible.

I am re-quoting what I wrote below because they clearly state that it is not possible if they want to respect the deadlines.

Page 26: > The study concludes, without any ambiguity, that a sustained development of electrical renewable energies is essential in France to respect its climate commitments.

Which defacto exclude a 100% nuclear mix. (According to the report, maybe the report is wrong)

> How is it possible that they managed to build a nuclear reactor in 5 years in the 80s and can't do so now.

> Given modern technology, shouldn't they not be at least 2-4x more efficient at building new capacity then they were in the 80s?

I know right? I have a hard time wrapping my head around it too. In theory that's how it should be.

But in practice, it doesn't seem to be the case. Most projects end up being giant clusterfuck with years of delays and billions in over cost. And we keep seeing the same story repeating over and over. There is lack of qualified people and expertise got lost (the famous welders). We can probably train new people but can we do it in a sufficient timeframe and quantity?

There is also the problem of the massive amount of upfront capital to mobilize. Three bad EPR projects almost bankrupted the french nuclear industry. And we could also dive into the massive amount of corruption that goes with those large sums. Ohio being the last one of a long trend.

For the big plants, it seems that the costs and time to build have not fallen:

The answer is always that someone's just working for hire. Even repressive regimes are made up of 99% of people just doing their jobs to get their paycheck, looking the other way, or down. A great movie is "Cube".
Other countries have their own version of mass shootings. They often involve knives, explosives, or vehicles instead.

You trade one for the other. Mentally unstable/unhealthy people commit mass violent acts regardless of the tools available.

In practically zero cases of mass shootings was the assailant completely mentally healthy. Taking away one particular violent tool is not going to solve the mental health problem in this country.

> Mining Ethereum doesn’t allow for much inspection of what you’re validating in each block.

Yes and no. It depends on what you mean by “validating”.

If your objective is to restrict the types of transactions that end up in the blocks you yourself create, you can recompile geth with a custom mempool implementation, and use that custom mempool to inspect the data of any pending transaction you want. This is how MEV works.

In other words, it is 100% possible for a technically-competent miner to only create new blocks that exclude blacklisted accounts, or that restrict transactions according to any number of criteria.

On the other hand, once a new block has already been mined and propagated to the network, there is nothing that a single miner can do to stop it.

If you start rejecting otherwise-valid blocks because they include blacklisted transactions, you will only fork yourself from the network. The rest of the miners will keep on building on top of the block you wanted to drop.
The "dual" standard RFC 8259 [1] (both are normative standards under their respective bodies, ECMA and IETF) is also a useful comparison here. It's wording is a bit stronger than ECMA's, though not by much. ("Good interoperability" is its specific call out.)

It's also interesting that the proposed JSON 5 (standalone) specification [2] doesn't seem to address it at all (but does add back in the other IEEE 754 numbers that ECMA 404 and RFC 8259 exclude from JSON; +/-Infinity and +/-NaN). It both maintains that its numbers are "arbitrary precision" but also requires these few IEEE 754 features, which may be even more confusing than either ECMA 404 or RFC 8259.

This seems to be a complete re-writing of the facts revealed from eye witness and video accounts of the events of that evening. The jury also seems to disagree with this alternate narrative.

It may be what some folks want to believe happened, but it is absolutely not the facts.
"It's not a philosophical question whether we live in an environment where objects are flawed. Around that are representing extraterrestrial technologies."

I can't make sense of these sentences. And the spelling mistakes are helping either.

"Today [Galileo Galilei] would have been canceled on social media."

For what exactly? And his this guy not seen the quality of social media commentary? The bar is loooow. Spectacular but unfounded claims are a mundanity and it's worrying that he's mixing these culture warrior talking points with science.

"Once I realized that we found an object from a technological origin that was produced elsewhere."

Unfounded spectacular claims just like this. The object is interstellar maybe, but where has he shown evidence of a technological origin? This is pretty important. How is it just left unchallenged?

It's a weird article. The video looks like a shot from The Thunderbirds and it reads like something from a local station affiliate run twice through translation software.

Yes Indeed. That way they'd learn that courts don't make legislation, which you seem to be confused by. Now that Roe v Wade is gone, we can actually legislate on the issue and reduce the polarization in American politics by coming to democratic compromises, rather than be subject to rule by court fiat.
And there are many more millions who are already here, and have been here for generations, and are US citizens.

The way you use language to promote your service doesn't reflect that.

You may want to say "Latino immigrants" or "Latino tourists", since those are small subsets of "Latino". Be specific.

Do you think Latinos are people that "come to the USA", as if they were all tourists and immigrants? Latinos are about 1/5th of the US population.

Why are you portraying Latinos as a network of 60 million of people informally lending money directly to each other? Do you even know 1 Latino person?

Do you think all Latinos are buying houses lending money to each other? as if any realtor would be remotely OK with that? What the FUCK

Intel calls it Linear Address Masking and AMD calls it Upper Address Ignore, however these will be available only on very recent hardware, and the Linux patches for them are still under development (see https://lwn.net/Articles/902094/ and https://lwn.net/Articles/888914/).
Fasting has multiple metabolic and cellular impacts.

As another commenter noted fasting triggers autophagy (self eating) where cells use parts/proteins from dead cells to repair themselves. The research and work done in this field won a Nobel prize.

As you note cells constantly die and are replaced but this replication is where a lot of poor genetic code can get copied into the new cells. One of the interesting things about autophagy is that through cellular repair cells actually live longer and don’t need to be replaced as often, this longevity and health of the cells appears to result in overall longevity and health of the subject.
It's a complex situation, with no universal driver, but I have put thought into it and your suggestions aren't entirely novel.

I'll use a recent situation as an example. Before I do though I wanted to say I am sorry that you're burning out. Knowing this is the first step, and I hope you make a change or find a coping mechanism that helps you. I have been through the same situation a few times now. I'm never quite the same afterwards but I have been able return to being a productive worker without radically rethinking my life.

I worked with someone who in my opinion was extremely entitled, prioritizing activism and social issues above getting work done. This company tolerated a lot of it (California company), however, the reality is that work had to get done. If only this person put as much effort into their workload as they did their complaints it would have been a non-issue.

It killed morale and this person eventually had a negative reputation, and was let go. It was bad. A bunch of meetings, talking with folks, but after about 3 months of work there was a hello world, a readme, and a "demo" app in the wrong language that didn't even showcase the crux of the problem that was targeted.

In my opinion there is a time and place for stuff like this, and we must never forget we get paid to produce work.
