In pop-science articles and videos, the concept is usually illustrated using the dated but intuitive model developed by Niels Bohr around 1918. The model envisions electrons that travel around the nucleus in circular orbits:

Please stop teaching the history of what we used to think the atom looked like. We’ve reached the point where we spend 99% of the material teaching what we know the atom doesn’t look like and very little on what it does look like. Even this author offers a picture for what it doesn’t look like and nothing for what it does. Physicists should know the value of a good picture/mental model better than anyone else.

I challenge you to go on Wikipedia and find the article/space for the current understanding of the atom. Was that hard for you to find? Would a curious high schooler have enough information within that article/space to learn everything you now know (textbooks are too expensive and inaccessible for high schoolers to rely on, physics websites are hit/miss). Is this how you would prefer to have been taught?
Woah. Well that just adds to my confusion!

> Typically spike protein can be detected for a few days after vaccination, but some participants with PVS had detectable levels more than 700 days after their last vaccination.

Something like this; cells with vaccine RNA are producing spike protein (at least) but are spared by the immune system, possibly for good reasons (such as being part of critical organs or tissue).

These cells will eventually recycle, which is why the symptoms dissipate over years.

Unfortunately, the vast majority of jobs and manufacturing is in The lower value manufacturing chain. So by chasing only the high value chain, you abandon the manufacturing operations that actually hire workers, thereby hollowing out the middle class of your country and reducing the consumers of the products that you sell. A counterproductive and shortsighted strategy.

That's true. They were numerous attempts to introduce a European alternative, which (more-or-less) failed. The US cloud providers are years ahead. However, the EU is suffering from that; the US companies pay some taxes, but far less than you possibly believe, and it conversely doesn't have any tax revenue from their own companies. Not to mention the political and data independence that are now more necessary than ever.

Show HN: Malicious code detector
Hey HN,

I built a GitHub app that detects malicious code in pull requests and notifies or blocks them. Alongside it, I published a Semgrep ruleset for any stage of the CI/CD.

I started this after getting frustrated by all the FUD around malicious code - lots of noise, little effort to solve it. While discussing new threats is important, hyping every piece of code no one ever uses isn’t helping.

That said, malicious commits are a major attack vector - a stored RCE, with the codebase itself as the sink. That’s why I built this.

Would love to hear your feedback.
Cheers, Matan
Direct methanol fuel cells are a thing. It may not fit your definition of efficient but that is the technology I think should be pursued. There are multiple biological, chemical and electrochemical pathways to produce methanol. That means that there could be an economic way to produce it nearly everywhere.

Another interesting technology is redox flow batteries. The fluid itself is charged. Fluid storage can be sized to the charge/use requirements. Or you can haul in "charged" fluid. But since the fluid is not consumed, discharged fluid would need to be taken away. Making hauling is less efficient.
It would help improve things if universities, not the government, was responsible for student loan debt. Schools have no incentive to lower costs when they have no liability
Function calls are very fast (unless there's really a lot of parameter copying/saving-to-stack) and if you can re-use a chunk of code from multiple places, you'll reduce pressure on the instruction cache. Inlining is not always ideal.
This part made me laugh.

That’s likely.

Say more. That kind of thing sounds worth paying for.

For example, someone might secretly think state school education was a waste of time, but not want to talk bad about their peer’s schooling. Or want their child to socialize with other well-to-do families.
Which measure are you going off there? Because I see the "Chance a poor student has to become a rich adult" metric at 41% for UC Riverside and 58% for Harvard.

There is the "overall mobility" metric that favors UC Riverside, but the way that's being measured would seem to skew in favor of whichever college has students in lower quintiles (a top quintile kid can't move up 2 quintiles).
It's between 20k and 30k dollars. Maybe your profession is suffering from "industrial bias": it focuses only on high-end robotics because it's the only thing that makes sense economically for now and anything super-cheap is seen as laughable ? Wasn't it the case for FDM 3D printer too before they went mainstream in the 2010s ?

I just want to build a toy and explore what's possible with this technology for non-serious applications. The servos may wear too quickly ? I'm fine with that. However I have trouble figuring out how cheap I can go. If I can carry out a task using the "control arm" and the "working arm" performs ok, does that mean Aloha will be able to learn it ? What are the limits then ? What if my arms are really flexible (as flexible as a 10 cm section of a PLA filament for instance), but I manage to carry out the task, can something based on policy diffusion learn to handle the task with "bones" that flex and oscillate ?

I liked Slashdot's old moderation system, where you had a drop-down, and you at least had to choose from a few preset "reasons" for your moderation action. It's not perfect, but it might at least cause a few people to pause and reflect on why they feel such a strong urge to get rid of that headline.

For HN, you could map the drop-down contents directly to submission guidelines:

- Poor/incorrect title

- Non-original source

I just searched for "best predictor of career success" and found a bunch of conflicting results. Open networks, conscientiousness, grit, intelligence, class, etc. This is actually reassuring, since if there were a known path to success everyone would crowd into it. Curiously I didn't see any articles or studies saying "it's partially random" because no one wants to hear that.

I think academic prestige is best understood as a safety net. It won't guarantee success, because nothing can, but it can do a decent job preventing failure. In that respect the parents are right. Academic assistance is a way they can convert financial resources into something that can't be taken away from their children (and isn't subject to the gift tax limit).

That said it's easy to go overboard, and many do. Unless you want to work in a small number of careers that have target lists of schools they recruit from (which again is because the credential is a selling point to clients, not because the education is better), there is no difference between a public university and a prestigious one.

To the extent parents know that prestige is signalling all the way down, and does not imply being better at what you do or knowing more about your subject, they do have some inside perspective compared to the population at large.

Aren’t the 0 and 1 states of a qubit basically the zero mode (ground state) and first mode of the quantum system? So, there can be superposition of the modes, but when measured (with an EM pulse), it either re-emits the pulse (producing a 1) or absorbs it (producing a 0). Is that correct?

I recently learned there are qubits that have more than 2 modes… like a qutrit, with 3: https://en.wikipedia.org/wiki/Qutrit

I mean, isn't the US saying that taxing imports is an ideal source of revenue?

But at the end of the day, there was never any real incentive to make an EU-native alternative. Now, there is. The US is in an uncertain state. Will American be great again? A fascist dictatorship? Argentina? Who the heck knows. Right now, we have a lot of speculation about what's going on and precious little information.

Unreliable partners give a very, very strong incentive to have critical infrastructure local.

Beyond that, what's the downside? Before, it risked triggering a trade war. Seems we're there already, and going local just gives a stronger hand.

Its never been a good idea. I do not think non-EU European countries can rely on EU cloud, not can EU countries can necessarily rely on each other.

The only effect the distrust of the current US government will have is a few articles. It expensive and difficult for this to be sufficient incentive to change anything.

We should probably grateful they have not put it all on Chinese clouds.
I'm sorry that I didn't get the chance to reply to your original comment before the downvote brigade chilled your speech. If I recall correctly, your question was an interesting jumping off point for a discussion about the difference between information theoretic "simplicity" and code that is readable and simple to reason about.

Lisp seems to have a sort of almost mystical promise that maybe in some fundamental, mathematical point in conceptspace, the two forms of "simplicity" converge. I think that Lambda calculus, like quantum mechanics, gives the lie to this promise.

The Church numeral for 9 is not a very readable symbol for human beings, but the Church numerals as expressed in binary are more compact than an ASCII or UTF-8 representation of those numerals, and once they've been defined along with a few operations, you get big swaths of number theory stuff "for free".

It might suit some highly motivated people but the pressure of meeting all the deadlines which have heavy costs for missing (like repeat the entire paper next year and pay again) keep many students actually doing it instead of procrastinating forever. So does the pressure to simply get out of bed to attend lectures instead of learning whenever they feel like. It does sound silly but humans are weak and useless at doing things they don't want to do in the short term with nebulous future benefits.

This happens with mortgages too. People with a mortgage tend to religiously pay it off as required so they don't lose their house while people without, somehow don't manage to build equivalent wealth even though they could be scrupulously investing their spare money just as much. And once you have a house, it's easier to keep it than to keep a pile of money. Often when people die, almost their only wealth is their house. Where did all the rest of what they earned their entire life go?
That's awful.

I just tried uploading a couple files from PC to Android phone, ublock Origin had marked sharedrop.io as potential badware, disabled it because I knew it to be decent software, then once the file was uploaded (not before), I watched with horror as it redirected me to limewire and showed me that my file was in some bucket probably on some server that I never meant for it to go!

Thanks ublock Origin, I'll never doubt you again. Unless you get bought too. No one is safe.
The proposal seems to be to not build anything, because it's a problem if apartments for single people are built.

I think we all also agree that it's a problem if housing for families is not built. But the route to more housing is rarely through problematizing other types of housing.

There is a story of a student taking an oral exam at Oxford or Cambridge many many years ago.

Examiner: "What is electricity?"

Student: "Oh, I do know, I mean I used to know, but now I've forgotten."

OVH and Hetzner are quite decent and popular. The alternative does exist and I've used it a bunch, it works.
Binary size was a concern, so excessive inlining was undesirable.

And don't forget that any asm-optimized variant always has a C fallback for generic platforms lacking a hand-optimized variant which is also used to verify the asm-optimized variant using checkasm. This might not be linked into your binary/library (the linker eliminated it because it's never used), but the code exists nonetheless.
I know people are being very nice and considerate, and that's the correct thing, but I've always despised this type of schizophrenic word salad. The obtuse and pompous language to describe "theories" that would sound silly if stated simply, the allusion to Secret Knowledge with the Cool Capitalization, the repeated statement of their enlightenment and the foolishness of the "sheeple". It is dripping with arrogance.

Yes, there's other mental health reasons for writing this, but I think we tend to ignore this also comes from a place of vanity and self-importance.

It probably should be noted that the reason the drift velocity is so much lower than velocity due to thermal motion is that electrons cannot move very far before they collide with an atom which changes their direction.

The mean distance they move in a copper wire between collisions is about 0.00000004 meters. At 100 km/s it would take 0.4 picoseconds to travel that distance.
This is too political for HN; and downplays any concerns regarding the alternative, that may have incentivized people to abstain rather than support either.
As someone who has studied the American constitution and been actively engaged in much civil discourse locally, I firmly believe and comprehend the logic of an unmanageably large “government” being a very bad thing on many levels. Please explain to me your obsession with a massive tax funded “government” and your thinking behind a comment such as the one you made. Why do you think this way? Nothing could be more in line with the American forefathers vision than what trump and Elon are doing by dismantling a grossly overweight, fraud ridden, and useless system that the US calls much of its government. I’m eager for a cogent argument, that blends constitutionality and logic, for such a broken system. Hoping you’re the one to make this argument

Of course it takes time for domestic competition to arrive. Decision decisions cannot only be made because the benefits are not immediately realized. It’s taken decades to get to the point that we are with the outsourcing and oversees manufacturing that has emptied the ability of the US to manufacture basic products. The bottom line is that the products these CEOs are selling need to have a higher price. They’re being subsidized by slave labor and foreign subsidies. The prices will increase. The margins will increase and new domestic competitors will emerge to take advantage of the increased margins, but it takes time. And dismissing it because it takes time is a self-defeating policy.

In theory, competing firms keep each other honest. In reality, the managers care more about their petty kingdoms than the health of the corporate empire. If theirs goes bankrupt, they use their skills to build a new fiefdom elsewhere.
