Question:

How was the first Hydrogen atom in the Universe created from empty space?

In fact -- how are any Hydrogen atoms created from empty space?

(Because that's quite the trick... if you ask me...)

If you have an answer for that question -- then I challenge your knowledge by asking that you prove that knowledge with a lab experiment...

Produce for me, in the lab, using whatever equipment you like, one single teensy Hydrogen atom -- out of nothing but empty space...

Produce for me a single Hydrogen atom -- in a vaccuum...

You see, if someone understood how to do that then that would be a huge understanding for any material scientist because if they could do that, then

They would understand how matter is created in the first place...

Which is sort of the root level understanding for all material science (if you think about it) for Hydrogen and every heavier element and compound than Hydrogen... for everything material science related...

Please tell me that you as a material scientist -- actively seek this knowledge...

Why?

Because if I were doing material science, I'd be actively seeking that knowledge, as a foundation for everything else...

For everything else that would exist subordinate to, and on top of (to use the foundation analogy) it, or below (to use a pyramid/hierarchy analogy) it...

Why?

Because I don't know how Hydrogen is created in the first place!

It seems like that would be the place to begin any and all material science research/experimentation, that is, how the first material in the universe is actually created, wouldn't it?

If it could be discovered, then that would be the first principle -- from which all material science would proceed from, from which all other principles in material science were derived, wouldn't it?

Me, well I claim Socratic Ignorance in the matter...

I don't know -- but then again, no one pays me to, so I guess that's OK! <g>

On a serious note though, it would be really good information to have, do you not agree?

1 bitcoin is worth $50,000 and has less utility. Tesla stock is worth more than every other car company put together, yet I don't see half of global car sales being Tesla.

Are you suggesting that the government should not allow people to freely trade bits of paper between themselves based on your view of how valuable something is?

Yes, just trying to point out the flaw in the "velocity of money" idea as it relates to debt.

Multiple layers of lending on a single dollar is building a house of cards. When everything works out you get a nice house. When one of the legs fails the whole house comes tumbling down. This is not a good way to build an economy.

>If Robinhood continued to allow trades then they could be accused of being complicit in market manipulation.

They can be accused of anything but that doesn't mean it will hold up under any scrutiny. Brokers aren't obligated to make decisions on market manipulation -- that's the SEC's job, who does it quite poorly as we can see from this episode.

> For an unintentional payment, I agree. For an accidental overpayment,

From the article:

It has to be really frustrating for local municipalities / regions who want to make it desirable to life / work there ... but they're in a hole of crappy internet determined by some monopoly that isn't responsive / responsible to anyone.

I know some local areas near me are just SOL as far as good service goes. The local monopoly actually has run lines across people's yards and just left them there exposed for years. Some folks just bury them themselves... they're doing work for the company, so they don't accidentally mow over their neighbor's internet connection.

Sure they do. Those people are called shareholders.
I’m interested to know why you’re placing the blame on Robinhood.

They would have carried on trading $GME if they weren’t called up at 3am by NSCC with a demand for $3 billion security.

I’d be interested in knowing how the NSCC came up with this figure and why they deemed their approach as acceptable.

I also use a Leopold with silent reds (750R).

I borrowed one a year ago and geez, it was nice! I had used Cherry blues, browns, and less common Kailh Box whites [1] prior to that. I enjoyed them, but the noise reduction silent reds brought was refreshing.

And apart from switches, that board introduced me to Leopold, who I think sets the standard for mass-produced mechanical keyboards. No odd shape or cheap-looking shiny plastic (DAS!), the keycaps are top-notch, and they come with lubed stabilizers. Heck, even the cable can be routed multiple directions to your liking.

Overall, Leopold's build quality is something I've not experienced with a handful of other mass-produced mechanical keyboards I own. I'm convinced I'll need to go custom if I want something better.

Personal emails DO NOT change a lot. This is dishonest because they change extremely infrequently as a universal contact identifier.

I had an email startup. Emphasis on had. People are very reluctant to switch email providers and email addresses.

What may change more are business, affiliation, and ephemeral email addresses, but most people don't go around changing their personal email addresses like bathroom wallpaper.
Oooo this is exciting. One of the annoying things about "traditional" raid is that making a raid group gives you performance, but it also kneecaps your rebuild time.

This is because you need to do a coordinated read from each disk in the raid stripe by stripe. a rebuild is effectively a single threaded synchronous operation

We don't really need to have such rigid mapping of data to raid groups anymore. which is why most large storage systems partition your data up into small chunks (a few megs) apply some forward error correction to it, and smear it all over the place.

This means that you can do multi-threaded rebuilds. This means that as your array gets bigger, not only does the rebuild time get smaller, but its much more resilient to data loss.

A good example of this is GPFS's native raid: https://www.usenix.org/legacy/events/lisa11/tech/slides/deen... (https://www.youtube.com/watch?v=2g5rx4gP6yU)

A word of warning though. Don't do this for small arrays (<50 disks) its not worth the hassle, yet.
Even people with access use scihub. It’s just easier than whatever institutional login crap they throw at you.
I think, one good way to go about answering this is to see if you can find articles, blogs talking about Netflix's engineering and how it evolved over time. They are a huge proponent of microservices and kind of popularised the concept.

IMO, mirco-services make a lot of sense for high number of users, B2C global products due to the challenges and huge complexity in terms of distributed systems, users, end cases and makes for a great use case.

For simpler B2B products with not a lot of complexity in terms of engineering. Mononlith, does just fine.

This is vastly different from insider trading - they're not even comparable issues. You could at least reasonably argue a case for market manipulation (though I'd still disagree).

You can't say this is insider trading unless you generously expand the definition of insider trading to include every kind of wrongdoing in the market. Robinhood executives didn't trade GME and didn't have any nonpublic information.

These definitions matter.

I've lived in places with local Co-op's for broadband and phone service (in Kansas) it was some of the best service I've ever had and cheaper too. They only did this because the larger companies were ignoring them and not giving proper service since it was a smaller community. In short, banning these is bullshit it should rather be encouraged.

> I have an older unicomp and a newer unicomp since the retooling last year.

How does the newer unicomp compare to the Model M's? I have three Model M's (work, home, and spare). I bought a Unicomp around 2010 because it has USB but had to give up on it because it required too much pressure and gave me mild CTS, something I've never experienced with the Model M's.
I think Robinhood fucked up greatly here in the eyes of their customers, even if they had no real choice in the matter, but they stopped the buying of a dozen or more stocks (e.g. AAL which was not at all targeted by WSB) that had their reserve requirements increased. I believe normally its in the single digit percent, many of them were increased up to 100%.

That’s the fate of most ‘code editors’. They start as a lightweight replacement for heavy IDE’s, but becoming more popular, getting more and more features just to end up as heavy as IDE’s, but with less features still.

Dead on arrival given the current state of the House. I can't even understand why anyone would propose such a thing other than to gain support from the big network companies.

> it was financial regulation

By “financial regulation” do you mean capital requirements being set by unknown individuals at the DTCC according to a formula that is unknown to the public and, by his own admission, even the CEO of Robinhood himself? I don’t know what I’d call that but it’s not what one typically thinks of as financial regulation.

Anyways, whatever happened to these types of games? Did it just die out as computers got more powerful, and everyone just played first-person shooters or 3d role playing games?
I honestly don't think it's actually an outlier issue.

In highschool almost everyone I know got into smoking pot, at least for awhile, and within a year or two 90+% of them just lost interest in it, maybe 5% kept using and maybe a quarter of them literally made pot the center of their lives and are still daily users with big impact on their lives and careers (or, honestly, lack thereof for all but one). The same thing happened with alcohol.

As an adult, I've seen the same pattern repeat for people who just didn't try things, for whatever reason, or perhaps people who changed.

What's actually happening, IMHO, is that you have a ton of overlapping processes that are filtering for with people who are vulnerable to becoming addicted to a given drug. Obviously those people will have trouble quitting.
> For my part, one of the most costly ways I've seen it manifest is a culture of treating staff time as free in comparison with any expenditure. Getting a purchase—even say a £10 book—is a protracted process that ends up draining hours of multiple peoples' time trying to find and convince a budget holder and get the right forms signed, and even that often doesn't meet with success.

1000x this. First it's ignoring the opportunity cost, but there's also the lack of acknowledgement of staffing costs (as they are considered sunken) - the person's pay was already budgeted for, but the £10 book hasn't been budgeted for. Also using up the time of senior (valuable and expensive) people in these kinds of processes. The argument is always that it prevents fraud or corruption, but anyone who knows internal processes would realise that there are far easier (and more lucrative) ways to commit fraud or corruption than the travel expenses system, that would be far harder to detect, and far easier to explain away.

2 more big problems that need solved (one of which alludes to your point):

- Your book is a capital expenditure, but the people administering the kakfa-esque process of approving your expenses are paid as opex. Your department has an Opex budget it aims to spend each year. There's no recognition that "money is money" -- if your budget is for capex, it cannot be used to buy a book! And vice versa! In some organisations (generally handling research grants), money is further ring-fenced into buckets like "Travel & subsistence" and "consumables". Even mid-pandemic, good luck spending money set aside for Travel & subsistance on a consumable, even one arising directly from not being able to travel...

- Annualised accounting, meaning budgets disappear into thin air on the 5th of April, thus driving spend to happen sooner than it needs to, and creating a culture of "spend it or lose it" - the inability for funds to roll over, even when there's a good reason, leads to programmes being pushed to spend more money faster. Letting funding roll over, by allocating budgets as "cash" would be so much more effective.

I hope ARIA will be able to escape from annualised accounting and simply spend its budget, without worrying about capex/opex etc.
It makes sense for lustre, as you can remove the hardware raid controller and just use "dumb" jbods.

Alternatively, you can also move the gc "backwards", changing the black object. In Lua, sometimes the write barrier recolors the white child object to grey and sometimes it recolors the black parent object to grey.

IIRC, the motivation for going backwards is that if you assign a large number of white children, recoloring the parent once is faster than recoloring all the children.
You misunderstood my point. Bias exists and I have accepted that, and I won't unsubscribe from good reporting because of bias.

Giving into left-leaning fashions is bad not because of the "left-leaning" part; its bad because of the "fashions" part. It's lazy groupthink at best, and bullying people into conformity at worst.

Have you noticed how narrow and specific all of the rules for reporting have become? Do you honestly believe that leftism is defined by these narrow rules, many of which are changing rapidly?

No. Most left-leaning people don't believe this stuff (how could a normal person even change their beliefs from one day to the next?). They go along with it because either they are too scared of getting bullied themselves; or because it's mostly hurting the right, and they believe they can regain control of the discourse after the right is diminished.

But it's easy to destroy good discourse and hard to rebuild it. After the right gets marginalized, we won't go to open-minded chats over coffee among left-leaning folks. It will be these same horrible tactics over the most minor differences of opinion on the left. Proponents of socialized medicine will be doxxing proponents of Medicare for all. There will be no end to the ridiculousness.
> Their actions were directly responsible for a huge number of people being financially ruined

Wallstreetbets pumping penny stock is directly responsible for it. They tricked tons of people who had no understanding of what’s happening and no exit plan into believing it’s a fight with evil guys, that will leave you with big profit. Both of those were BS.
What’s the incentive to innovate?

Other smartphone companies are “innovating” with many failed attempts. Apple gets to avoid the failures, refine the feature and deliver successfully.

“Playing catch up” isn’t an issue because Apple can bring any Android feature (hardware or software) to the iPhone in 2-3years.

For example the Swipe keyboard. I needed to wait a few years to get it after I switched from Android to iPhone, but I didn’t mind too much. Meanwhile, thank goodness my phone doesn’t currently fold and break right now. I’m happy to have a folding phone when the tech is 10x better.

Yeah. Another one is that people are often blind to what’s going on with the birds too.

A while back I trained myself to observe plants, birds, etc.

There will be stuff going on like a hawk swooping in to kill a bird and nobody even notices but me, just because my brain is sort of cued in to notice those things. There’s a nest with several hawks, and also a little falcon that hunts rodents about 3x per day, both right next to my house in neighboring yards but I never even noticed them before this.

It’s all about what you train your brain to notice, and once you start, you start to see it everywhere. If plants or animals are salient to you, you’ll notice them. If not, you won’t.
No current firearms designer is dumb enough to put nonessential electronics in the critical path.

The State of New Jersey has/had a law[1] that would require all handguns sold to be outfitted with smart gun technology within X months of said technology becoming available, that would prevent the gun from firing except when in the hands of its authorized owner.

At the time, it was assumed that would take a form like, the owner needs to wear a special ring on the hand that would grip the gun, and the firing mechanism would sense proximity of the ring. The nightmare stories that could arise from that pretty much write themselves.

But my point is that, even if manufacturers aren't that dumb, politicians are.
