Yes, it's called SIPC, you're fine unless you have over $500,000 in robinhood.

I read it and disagree with you.

First of all the way that private equity works is exactly what he says. They take a healthy company, have it take out a huge loan, use that to buy out the current owners, and then hope to make money every way that they can. First, the private equity company gets paid for the deal. Next, they get paid to manage the company. Next, they look for every way to cut expenses to make the company's financials look better (even if only temporarily). And if they succeed, they flip it.

If it implodes, the debt goes away with the company and they don't get to flip it. But the private equity company already made a profit. So "the company survives" is a nice to have and not part of their business model.

The people who lend money for this are the ones at real risk. But if there is enough money looking for places to be lent, some of it will go to risky bonds.

Moving on, his definition of a zombie company is one whose earnings before interest, tax, depreciation and amortization (EBITDA) has not been sufficient to cover interest for the last 3 years. Such a company might actually be viable, but only if it has prospects of future earnings that are massively better than current ones. There are some companies for whom that is true, and no all zombies are actually going to fail long-term. Certainly Tesla and Moderna seem to have decent futures.

But most of them won't hit those dreams. Particularly not the ones that private equity got involved with. And the longer they last, the bigger the crater when they implode. But if you have extra rescue money that has to go somewhere, the zombies will be happy to take it to stave off disaster for a little while longer. And apparently they took a trillion dollars in debt in the last year.

How much of that trillion do you think that they will collectively manage to pay back? I mean, without taking on more debt down the road...
It's not an extreme reaction to see a company like Robinhood bending to the will of its real customers, aka Citadel, and concluding that they were both running out of liquid money because they allow instant trading for new users AND that they protected their customers from getting wiped out by limiting the ability of retail investors to buy GME.

Billions of dollars were on the line.
HN upvotes what HN wants to see. Apple is one of the biggest companies in the world with products that a large majority of HN commenters use, and this blog post is in-depth technical praise / validation written by a representative from one of their biggest competitors. It feels like classic top-post material to me.
Your post above doesn't mention GPL compliance, only vendors using ancient versions of open source code. If you don't have the source, of course you can't do anything. So you ask the vendor for source and if they refuse then you contact the Linux kernel community to enforce GPL compliance. At some point the source will come out, even if the vendor has to get sued in order to do it.

https://en.wikipedia.org/wiki/Loongson#Hardware-assisted_x86...

"With added improvements in QEMU from ICT, Loongson-3 achieves an average of 70% the performance of executing native binaries when running x86 binaries from nine benchmarks."

Loongson is MIPS which executes x86 binaries at 70% speed of native execution. Using QEMU.

QEMU is not unperformant.
krunvm uses libkrun (https://github.com/containers/libkrun) for executing the VM, and while the later is also based in rust-vmm and shares some code with Firecracker and Cloud-Hypervisor, it's specialized in the process isolation use case. This means it implements a different set of devices (most notably, virtio-fs instead of virtio-blk, and virtio-vsock+TSI (Transparent Socket Impersonation) instead of virtio-net), and it takes the form of a dynamic library instead of a final binary.

In fact, the networking limitations are caused by this use of virtio-vsock+TSI. TSI (WIP implementation here: https://github.com/containers/libkrunfw/blob/main/patches/00...) is an experimental mechanism that provides inbound and outbound networking capabilities to the guest, with zero-configuration and minimal footprint, by transparently replacing user-space AF_INET sockets with AF_TSI, that have both an AF_INET and AF_VSOCK personality.

TSI has the additional advantage that, for the host side, all connections appear to come and go to the process acting as a VMM (in this case, krunvm, as it links directly with libkrun), which makes it very container-friendly in a way that even side-cars (such as Istio) work out-of-the-box.

I hear your stocks can get lent out for shorting by others, which means you might not actually have them even while Robinhood is alive when you think you do...
It's a good post but:

" but a major one was the exodus of financialization experts from Wall Street to Silicon Valley. Suddenly the "get rich quick" mentality that had caused the 2008 crash was being adopted by senior leadership at Big Tech firms. "

Stop with these 'blame wall street' populist fantasies.

The 'fault' of 'whatever' is happening is 100% tech and it has nothing to do with bankers.

In reality, young people coming into the industry with a different set of values than those that came before them are driving this. A generation that simultaneously declares to be more 'socially conscious' is literally driving these activities, which is quite hypocritical.

The shift is easy to see: people having grown up more separated from their communities, with culturally secular values (not bad one's just more intellectual than rooted in relationships with those around them) can simultaneously detach themselves from the consequences of their outcomes at work, while at the same time participating in a 'protest' about something or the other in order to validate their self-identity as 'socially conscious'.

We're going to need a broad set of basic regulations, hopefully not too harsh, probably led by the EU as the only institution that seems to have enough power and wherewithal to care enough.

While note making any statement about politics - Biden's 'side' would be the most likely group to be concerned about privacy, and yet we haven't heard a peep about them on the issue. The other 'side' is deeply concerned about 'freedom of expression' which is good, perhaps they can find a way to make some legislation about it.

10 minutes sounds like a lot, I have a pretty common OMRON automatic pressure measuring device[0], and it takes about a minute to do the actual measuring, plus, say, another two to take off my sweater and put it back on.

I suppose I am missing something, how come it takes much longer for you?

I would not dismiss grafana + influxdb out of hand. You can embed grafana charts inside iframes, hiding the controls, driving it instead with parameters, it's a powerful way to add graphs to a larger system.
"treating your users as incompetent"

Actually, this is good practice.

We are all busy and distracted. Dumbing down an experience to it's essential aspects is a great way to make something easier to use.

If a 'fool could use it while trying to juggle' then that's good.

Making it dumb means speaking to intuition, not thought.

I should add, there are some good comments here about 'command line' etc. - I suggest that that makes sense but in an entirely different realm of usability.

Designing for something that's going to be used by competent people all day for their jobs, is different than designing for the proles standing in line at the bank, looking for 3 minutes of respite from whatever, or even trying to squeeze in that little update.

I keep confusing QEMU with the extended memory manager thing I used in 80’s, which is https://en.m.wikipedia.org/wiki/QEMM
The key is that libkrun (https://github.com/containers/libkrun), the library that krunvm uses for running the VMs, as recently integrated support for Hypervisor.framework on ARM64, in addition to KVM.

As for buildah, the Homebrew repo contains a build that includes this PR (https://github.com/containers/storage/pull/811).
I have tried TabNine extension that does the same and I wasn't impressed with the results. Maybe it depends on the project and maybe the paid Pro version is better, but the suggestions I get are routinely worse that the default IDE suggestions.

TFA is linked at the top of this page; please assume we can all read it. There is one reference to airlines, which reference includes several links to financial sources documenting (uncontroversially, one would like to assume) that they are harmed by massive drops in demand for air travel while they benefit from the receipt of hundreds of millions of dollars from the government. Taibbi takes Sorkin's comparison of GameStop and Delta seriously, and invites attentive readers to ask themselves how different one firm facing reduced demand is from some other firm facing reduced demand.

Regurgitating a press release is not "actual reporting". We won't know what actually happened between RH and Citadel for some time, if ever. It's misleading to keep mentioning this in this context, because TFA doesn't address Citadel at all.

ISTR you have described RH as "a force for evil". I didn't disagree with you, but it's disappointing that your famous animus for one of the rare decent journalists in USA has preempted that judgment. Every time Taibbi is linked on HN you're around to slag him. You seem more opposed to Taibbi than you are to DNSSEC. When you read Taibbi you imagine things that are not in the text. What did he ever do to you? Did he cut you off in traffic? Did he steal your dog? What gives?
Yes, it's called SIPC and is (kind of) equivalent to the FDIC for banks. However it only covers up to $500k, only covers cash, stocks, bonds, CDs, and (I think) mutual funds. It does not cover options or future contracts.

Also it will only attempt to return the securities you 'lost' not their cash value. If you lose a lot of money due to not being able to sell your stocks for several days, that is not covered. So if you held 2000 stocks of GME, the SIPC will (eventually) give you back 2000 stocks of GME, not the cash value of those stocks when Robinhood went bankrupt.
These detractors want central "content policy" in the e2e and metadata-less Signal. They should simply move to other popular platforms.

OK, how hard it is to increase your credit line in real time. We are not talking 100s of billions here. Had RH reached out to the likes of Chamath or Musk, they would have gotten a credit line in minutes.

This is no excuse for screwing retail investors. Horrible management. I mean, I am some random dude who can think of these, these are professionals running multi billion dollar enterprises, c'mon.
There are a number of companies who do open source development and get paid for the development work that they put in, rather than selling the software itself. This seems like the least bad way to do open source things, although it is fairly incompatible with VC money, although ISTR RedHat has taken VC money at some stage.
Yeah, maybe he's a bit over the top, but he's got a point - and that point is that governments all over the world are indebting themselves to keep their economies afloat, and all that money ultimately keeps making the rich (be it hedge funds, the wallstreetbets guys or other investors) richer and the poor (who don't have loose cash to invest in stocks, but will have to pay in one way or another for the debts taken up by their government) poorer...

That quote literally comes from a section titled "Hardware-assisted x86 emulation", so I don't think it would necessarily be fair to attribute all the performance to QEMU. FWIW, getting results that good almost always requires hardware MMU support, which is usually the largest bottleneck in these kinds of things. Without that you'd be lucky to get within the same order of magnitude.

Furthermore, having worked with QEMU in several binary translation and emulation projects, I cannot say that it is designed with performance as its first priority–TCG's number one consideration seems to be portability and ease of supporting new architectures. If you look at TCG-generated code it's pretty "stupid"; almost no optimizations are applied at all. This isn't necessarily something I fault QEMU for, it's just clearly not a priority. Or hasn't been, I guess; but it seems like this might be changing and I'm very interested to seeing where it goes.

Interesting that the old and creaky financial settlement clearing for cash is creating a liquidity problem in the market for shares and derivatives.

AU/CA/EU have instant settlement of cross-entity transfers now, but not sure what the underlying clearing/settlement is.

Great work!

Maybe have to reconsider layout for big screens similar to mine. But browser resize is fine for now.
Security researchers sometime publish informative blog posts from time to time that don't deal with a specific vulnerability; this is one of them. Of course, being Project Zero usually these deep dives often turn up a bug or two (for example, this document on Apple's PAC implementation, which is probably one of the best resources describing it, stumbles upon a bug fixed by Apple while it was being written: https://googleprojectzero.blogspot.com/2019/02/examining-poi...), but this case it does seem like they just happened to not find anything. Whether that is because they couldn't probe very deeply due to the complete rewrite, or because the new architecture and use of a memory safe language upped the bar a bit (or a combination of both) is not clear but the thing I wanted to say here is that these blog posts are useful regardless of whether there is an exploit PoC attached. People may not want to write them, but they certainly stand on their own as good reference material.
I'd bet my house all the CEOs and Wallstreet have less than four degrees of separation between each other.
A similar recent trend that really bugs me is apps on OSX that run in the background, with a presence in the toolbar at the top of the screen used to be closable with a single click on the icon, move the mouse to the last item in the menu, which always used to be "Quit".

Now it's hidden under layers of menus on purpose.

The worst experience I've encountered is Adobe Creative Cloud. They force you to open the app with the icon, then use the main menu of the app on the other side of the screen to choose "Quit Creative Cloud" to then be presented with the following choices:
(Cancel) (Quit) (Hide)
"Hide" is highlighted and "Quit" is the one you just asked for. Perviously that step would pop up a nag screen begging you not to quit the app, but that no longer happens.

They are obviously testing various ways to become "stickier". And with each iteration it gets more and more difficult to close. I just want my RAM back please!

I found quite useful an example I read in the book "The Art of Unit Testing" by Roy Osherove, it was something like this (I don't have it at hand, I repeat it from memory):

Suppose you have to test the irrigation system of a tree in your garden, you want to test how many times and how much water is used, you have two ways to do it:

1) State-based: run the system for a few hours, during which it should water the tree several times. At the end of that time, you check the state of the watered tree: Is the soil moist enough, is the tree well, are the leaves green, etc. (Obviously this is just an example as this test would be complex in real life, but it is to get the idea across).

2) Interaction: We place a flow meter, a device that registers how much water is flowing through the device and at what times. At the end of the day, check that the device has been called the correct number of times, with the correct amount of water each time, and we don't worry about checking the status of the tree.
With the (potentially huge) caveat that any losses you suffer due to not being able to sell your stocks in the period where you SIPC claim is being processed is not covered.

We've seen plenty of trading problems due to direct human error, and we've seen plenty of trading problems due to software bugs.

If we got rid of breaking trades, it would presumably force everyone to use carefully specified systems and use avionics-like development practices. Maybe we'd even see machine-checked proofs being compiled to programs and smart contracts via the Curry-Howard correspondence. Long-term, it would probably be good. In the shot term, lots of fallible counterparties going bankrupt would be very destabilizing to the system.

This is all that day trading is. Regardless of whether the traders even know what a meme subreddit is. Why would any day trader want to use a platform that’s going to do stuff like cut you out of an epic short squeeze? If a non-professional investor had sensible ideas, they wouldn’t be day trading.

So what you're saying is by disintermediating share/derivative trading, one level of middlemen has been made obsolete?

Sort of like travel agents and airfares?

Why is this a problem? The fact that the share trading market is keeping these middlemen in place is part of the exploitation of the process.

Market makers perform a useful function in terms of maintaining an orderly market. Brokers don't. Especially ones that offer credit to their customers, thus hiding the risk to the counterparties of a trade.

I wonder if Robinhood is preparing for the possibility that its margin book gets blown up when GME inevitably crashes. Crashing price creates cascading margin calls and they can't liquidate their customers' positions fast enough and end up having to cover their losses, rendering them insolvent.

Sequoia, thinking that the fundamentals of the company are still solid long term and that they can wash their hands of this in an IPO in the near future, extends them a lifeline at absolutely brutal terms.

My serious money is invested through Morgan Stanley. They have institutional investment services I do not qualify for, but I'm on their registered investor account, and it's usually $7 to $15 for simple trades. It's not that much more if you're actually planning on executing in volume.
I'm not sure about this. If there's clear and blatant market manipulation on the part of the broker (which will likely get them hauled in before the SEC btw) then I imagine many investors/traders looking at this from the sidelines will be pulling their accounts as well, whether they're involved in this directly or not.
Preventing their users from selling out of a position would be much, much more serious than preventing them from adding to a position. Incomparably so.
Either pre-IPO trading or wait until the dust settles and then decide whether to buy or not.
