> I'm a professional fission guy. I started out in fusion and switched to advanced fission. These days I don't see why we don't just build lots more regular old LWR fission reactors.

Well, a comment posting without financials pretty much underlines why more fission reactors don't get built: the nuclear community is insanely bad at pitching to investors without magic on the line. Unfortunately, investors in our society are the closest things we get to planners so we're pretty fucked.
Some links to a couple other places covering this that might be easier to read and have more detail.

It's entirely correct. Note that the comment doesn't claim it stops all bot traffic, just that it increases the cost of creating fake accounts. Nor does it make any judgment on the morality or efficacy of such measures. People likely downvote such comments because they're reading something into it that isn't actually there.

> It doesn't have to, you just add a zero byte at the end of the embedded byte sequence in the object file. It's up to the programmer to make the choice how to interpret that.

Like, are you proposing that the ideal semantics for `#embed "foo"` if foo contained 0x10 0x20 0x30 0x40 to be to expand to `16, 32, 48, 64, 0`? That seems more annoying than the opposite, given that:

TFA demonstrated it by relying on sizeof() of arrays doing the right thing:

static_assert((sizeof(sound_signature) / sizeof(*sound_signature)) >= 4,
"There should be at least 4 elements in this array.");

You'd need to change this to subtract one every time, which sounds more annoying when embedding binary resources than adding the zero to strings would be.
Weird. I don’t see a lot of pure CRUD in enterprise development. It’s almost all dumb data transformation. Take data off a queue, add/remove/change, drop it in a db, pass it along.

Maybe take “REST” requests for reads or POST instead of dropping on another queue/topic.

Legacy code is C/C++ and PL/SQL. Java since 1.6 or so. JS/TypeScript now for frontends.

And a ton of RPC being called a REST API.

Python is exploding for all the ML/analytics being introduced. But that’s really it’s own thing. Doesn’t read like Python in any other domain. Just a wrapper around math libraries.

There were some suggestions to change 'imaginary numbers' to 'lateral numbers' but it is hard to do when the name stuck. Naming thing is hard.
Steam exists on the mac and steam exists on linux. The need for linux ports is dwindling now that Steam has developed proton, a sort of rosetta that converts directx api calls into vulkan api calls, on linux
One of my favorite examples of the reality of "imaginary" numbers is Euler's identity:

e^{i \pi} + 1 = 0

Or even better, raising i to the ith power:

i^i = e^{-\pi / 2}

That looks pretty real to me.

Forgive me, for I am doing an end-run around a HN rule (replying to a reply to a reply). But it seems an entertaining question...

> What if you radiated a Sun's worth of energy (10^26 Watts) out of 1 square meter?

* Blackbody temperature: 2 x 10^8 K.

Peak blackbody wavelength: Wolfram didn't like that question. However, it did helpfully note that it was twice the temperature needed for controlled nuclear fusion, and 5e7 K above the temperature at which the triple alpha process occurs inside stars.

It also noted that it was equivalent to 17 keV. This would, suprisingly to me, be X-rays and not gamma; the cut-off is 100 keV. 17 keV is a photon wavelength of 73 picometers (7.3e-11 m); a helium atom's diameter is about 62 pm.

* Luminosity would be about 4e15 lux. It would, of course, be twice as bright as the sun (equivalent to seeing both solar hemispeheres at the same time.) You would be able to see the Earth from lightyears away.

* Radiation pressure would be 730 x 10^12 newtons (80 gigatons).

* This would accelerate the Earth by 1.2e-10 m/s^2. Even if sited at one of the poles, that's only 4 millimeters/sec over one year. Not useful for jaunting around the Solar System except on geologic timescales.

* Asteroid Apophis is a whole 'nother matter. It's estimated to be 6 x 10^10 kg. Assuming we left its destruction to THE VERY LAST SECOND (i.e., distance 0), the radiation pressure would accelerate it at 36 km/s^2. (Yep. You try it: [0]; it's x 2 because it is reflecting) Of course, it would melt it in about half a nanosecond (literaly).

* Mars' moon Phobos would fare better. Assuming the radiator is a 73 picometer X-ray laser with 1.1 m diameter (1 m^2 area), beam divergence (based on no-doubt-poorly-applicable-in-reality formulas) would be about 2e-11 radians. At conjunction, the Earth and Mars are a maximum of 400 million km apart. Wolfram thinks (it ain't easy calculating the sine of 2e-11) the beam would diverge to about 8 meters wide at that distance. Phobos masses about 1e16 kg. It would only accelerate at 0.14 m/s^2, or 12 km/s/day. And it wouldn't melt for at least 80 milliseconds.

> Look, Apple isn't the only game in town when it comes to nice laptops, the Surface Book is really nice, but when you're comparing "computers I actually want to use for any extended period of time" $1200 isn't all that expensive.

And that's the point. $1200 IS expensive to some people who are only using it for basic computing tasks.

Some people do know what they are getting. They don't care about all the QoL improvements in more expensive laptops as long as they can afford it.

There are many ways to improve your UX skills. I've gotten to know UX here for 6 years. I'd start to research all the things about UX, try to learn from the foundation to advance knowledge, I found all the things related to UX on the internet, join the designer community (Facebook, Reddit...) to learn from each other and senior guys. Besides that, UI UX design tool can be very helpful to practice your skills, such as Figma (for pro player), Balsamiq, Miro, Visily (for newbie).
The only part that really makes me shudder is the thought of working to align with Amazon's 'principles'. Sounds like an oxymoron to me.
What? Royalty get a free lunch. Lottery winners get a free lunch. Trust-fund babies and the children of the wealthy get free lunches. All children who must legally be fed and raised by their parents for years get literal free lunches, and many get free lunches at school. Dividend receiving shareholders get free lunches, passive income businesses are free lunch generators. Poor people can visit charitable places such as some Sikh Gurdwaras and get literal free lunches. People who forage, pick fruit off trees or go fishing get free lunches. People find money on the streets and use it to buy lunch. People dig free lunches up from archaeology sites or beachcombing. People on welfare get free lunches. Government officials who take bribes get free lunches. People get free lunches for Christmas or Birthday. People attend seminars and conferences for the free lunches, and accept free lunches from prospective business partners or vendors. Thieves get free lunches. Landlords get free lunches. Foodbanks hand out free lunches.

Free lunches are everywhere. Children who learn that they aren't just by observing the world, aren't very observant.

> "Nobody gives away something for nothing."

Open Source software props up a lot of the internet, much of it given away for nothing. College students make a point of going round the dorms of wealthy international students who buy furnishings and electronics for the year, then leave it all out on the kerbside instead of shipping it back home. People around the wealthy Western world send stuff to the dump or to charity shops just to avoid the bother of putting it up for sale and collecting money for it. There's an entire website (FreeCycle) created just to organise giving things away for nothing. Google N-Grams records people giving away dogs with the term "free to good home" in the 1940s.
That's not keto then.
Is it? All of the state schools near me (east coast) are like $25k/yr in state.

Edit: that’s what they were 10 years ago when I was a student. I’d guess it’s more expensive now.
> closer we get to 0, the larger the number

From above. What if you approached 0 from below instead?

1/-1=-1, 1/-(1/2)=-2, 1/-(1/4)=-4.

So you just proved that 1/0 equals both positive and negative infinity, and therefore you also just proved that positive and negative infinity are equal. This is one of the reasons why giving 1/0 a definition is rarely seen as useful.
The US also has a large incompetent population, compared to Europe. Europe only recently got a huge surge of under-skilled refugees, and this should weigh down on the system (some countries like Italy/Spain are already near bankruptcy).

The US also spends a lot on its military, which is part of the social safety net. Europe ignored military for other expenses and is now paying heavily for it.

That being said, the US does not make good use of its resources. But it's a much harder problem that you'd expect.

Whatever that means
I exclusively use linux, and I wish there was something better than tar that was more widely used. In particular, that didn't have the problem of several subtly incompatible sets of extensions, and that had better support of using an index, especially in tandem with compression.

But that "something better" isn't zip. It's probably something that doesn't currently exist.

I would say Dreamweaver was OK, but it was eclipsed by the web-based CMS. Dreamweaver generated trash code when it was used as a DHTML design tool, but it was never as bad as FrontPage. When used in design-mode it would build up a model internally, and then try to generate code that it could later roundtrip. This worked when things were isolated, but as complexity grew it stopped working and was hard to debug.

I saw it work reasonably well when someone took a code-first approach with the overall website templates which avoided the mess from building these up using DW's code generation. You could then set it up so people could only mess with the certain parts of the page which avoided the overall site getting messed up as you added others. This got cleaner when they introduced Contribute.

Dreamweaver was created for a time when there was still a webmaster-type role in companies. These people didn't necessarily have what we'd consider a strong dev skillset, but the world around them had started to change which explains the range of capabilities in Dreamweaver.

Honestly, as someone that researches ML, this is my major concern. It isn't AGI that has the potential to kill us, it is current ML systems that can't handle OOD data and engineers put it in place because "that's the user's fault." Same reason we have Teslas crashing. AI safety might talk about AGI a lot, but their main area of research is modern systems and concerns over that.

OOD data is really hard to deal with FWIW. But personally I don't feel confident that adding more matrix multiplies won't generalize in a way such that OOD isn't of major concern.
hahah :)
All that remains is that the robots get called "Faro robots" and we're almost there.

I've been reading some old (early 1900s) diabetic recipe books from archive.org and it was a bit of a surprise to see how many recipes used saccharin back then (and almond flour, bone broth, etc.). I remember seeing saccharin tablets everywhere as a youngster, then they all suddenly went away. As it turns out, researchers found a higher incidence of bladder cancer in rats fed a diet of saccharin (20x the expected human dose, I think), which caused the production of saccharin to drop off dramatically. Up until that point, it was cheap, relatively easy to produce and plentiful.

Further research eventually proved that saccharin reacted with a compound in rat urine that caused crystals to form in the urine, which 'scraped' the bladder wall, causing injury, increased cell repair, and (therefore) an increased incidence of bladder cancer in rats. The researchers proved that this compound did not exist in human urine and crystals did not form, therefore the increased incidence of cancer should not exist in humans - and analysis of bladder cancer rates for lifelong saccharin users backed-up the new findings.

Still, the damage to saccharin had been done and I think there's only one plant in Europe that still produces it. I'm not sure how large the artificial sweetener market is (it seems to be growing exponentially), but every decade an old sweetener appears to fall out of favour and is replaced by a new one (or is added in combination with others). I'm not sure we're much further ahead than we were in the early 1900s!
To be fair, there are far, far more daily users of cars than firearms.

blame politicians ffs, not people who don't matter.

Politicians and parties base their platforms on polling data and voting patterns.

Sure -- it's a highly inefficient system, and there are plenty other inputs into their behavior.

But at the end of the day, they still have to actually win elections. It's a crap system in many ways but public opinion definitely matters.

> In my case, I served in the US Navy in nuclear propulsion.

Ah, the US military, famous for building and operating things at low cost.

> Truth is the tech works

Nuclear propulsion works because it has the US military to secure it but more importantly, a carrier or a submarine benefits from not carrying fuel in a way that has nothing to do with economics. You power a submarine with nuclear simply because there's no other way for such a submarine to spend months at sea without refueling.

You say the tech works. OK, but so what? That has almost nothing to do with anything. In fact you're extrapolating the military use case for using nuclear energy for propulsion and saying we should extend that to civilian commercial power generation.

As for the rest about over-regulation, the first point is that you have to deal with the political and legal reality. But really it's a smoke screen because proponents of nuclear power like to talk about operating costs while ignoring capital expenditure (which is massive). From a total cost per kWh over the lifetime of a nuclear power plant, it's not really that cheap.
I'm pretty sure there is only a tiny fraction of the population that is even willing to press the emergency stop when something bad happens. Most likely they will scream or freeze in place instead.

> industrial machinery that chops off hands

In the US South there's a ton of poultry workers that have lost fingers and parts of hands to machinery. It's gotten a lot better lately, but for a long time it was a very bad problem. Since most of these workers were Black or from Latin America, there was very little was done to protect them.

Whataboutism or whataboutery (as in "what about…?") denotes in a pejorative sense a procedure in which a critical question or argument is not answered or discussed, but retorted with a critical counter-question which expresses a counter-accusation. From a logical and argumentative point of view it is considered a variant of the Tu-quoque pattern (Latin 'you too', term for a counter-accusation), which is a subtype of the Ad-hominem argument.
My comment may not have been clear.

I'm saying I understand the idea that we can't divide by zero to make perfect sense. There is nothing arbitrary about it, which the parent comment seems to say. We don't just have a special rule saying "You can't divide by zero because we say so". It's a mathematical proof.
Okay, so they ask you to opt in and you say no. IANAL but AIUI opt out or trying to force the issue (like making it a condition of service) are illegal, so if they actually follow the law pretty toothless.
> Or some studies you can point me to connecting a low calorie diet with sustained weight loss?

https://pubmed.ncbi.nlm.nih.gov/19246357/

> Results: At 6 months, participants assigned to each diet had lost an average of 6 kg, which represented 7% of their initial weight; they began to regain weight after 12 months. By 2 years, weight loss remained similar in those who were assigned to a diet with 15% protein and those assigned to a diet with 25% protein (3.0 and 3.6 kg, respectively); in those assigned to a diet with 20% fat and those assigned to a diet with 40% fat (3.3 kg for both groups); and in those assigned to a diet with 65% carbohydrates and those assigned to a diet with 35% carbohydrates (2.9 and 3.4 kg, respectively) (P>0.20 for all comparisons). Among the 80% of participants who completed the trial, the average weight loss was 4 kg; 14 to 15% of the participants had a reduction of at least 10% of their initial body weight. Satiety, hunger, satisfaction with the diet, and attendance at group sessions were similar for all diets; attendance was strongly associated with weight loss (0.2 kg per session attended). The diets improved lipid-related risk factors and fasting insulin levels.

This is just one example, there's a lot more (you can start from looking at related studies on the linked page, for example https://pubmed.ncbi.nlm.nih.gov/15181047/). The first big study was already done in 60s and it was never refuted AFAIK: https://www.sciencedirect.com/science/article/abs/pii/002604...

But the findings aren't fashionable or convenient, so people tend to ignore them and cherry-pick any study that has more convenient results with miracle diets.
