I don't think this is the same as what you're referring to. Under the DTC rules, this would likely have been an "Additional Participants Fund Deposit". The rules seem intentionally vague about what happens if you don't make this payment. As far as I can tell, the rules allow the DTC to unilaterally demand an uncapped deposit from a participant at any time.

Fidelity has $3.3 trillion AUM. Imagine if all its customers decided to take some actions that led the DTC to demand an "Additional Participants Fund Deposit" equivalent to 100% of what's at risk, like in Robinhood's case. Would Fidelity's inability to pay that be viewed as due to a failing on Fidelity's part?

Actually thinking more about #5, there’s a class of problems where I think `any` is better than anything else: testing any kind of untrusted input type guarding. Granted `unknown` is safer in your program but `any` is most like the real world and you’re far more likely to catch mistakes in your expectations if you throw the compiler out the window and pretend it never existed.
My patience. :-)

People will compare browser benchmarks over milliseconds so why not file transfers over the home network?

In general terms, cynicism about the "need" may be right. Most home users in most use cases likely won't notice much by going to 10G.

But then there is the rest of us and the other use cases.

As for systems that can push this much data. Almost anything with a M.2 SSD will easily keep up.

So for a use case, backing up your zillions of photos to at least one other point of failure on your home network. May not be the best backup plan ever, but regular home users are not IT gurus and will do this.
That's very true, pushing for new projects regardless they are successful or not is a path for success. I think eventually this leadership need a successful track history to prove is worth investing in this person/leader projects

No journal is immune to being manipulated by skewed data. They (Lancet) in particular never truly lived down the vaccine-autism link fiasco. But again, I’m not going to declare that this data is cooked but I think it behooves us to approach it with a bit of skepticism. More so than if it were coming from a more trustworthy country.
There are no tunnels between NZ and anywhere which can’t be said for Britain where the Channel Tunnel carried >10 million passengers per year in 2019. UK airports have traffic numbers 7 or 8 times as high as NZ airports. Sea transport and shipping into UK ports is far greater and easier than to NZ.

I’m very glad NZ is COVID free but they got lucky by not having much community spread before the first lockdown and closing the border, and they are lucky by geography in this case.
In the 1990's there was a communication protocol named VideoLAN which was apparently intended to send video over ethernet faster than regular ethernet would do,

I found it used in professional print mastering where the large-format printer(s) which printed the masters were connected to an NT3.x server by VideoLAN using ethernet cable, then a second NIC having regular ethernet drivers connected the NT box to the artists' network who were using Apples.

With the amount of data they were sending in one direction once it got started, they were really streaming and apparently multicast was a click away when you wanted all the printers to print the same thing at the same time.

Naturally this was well over 20 years ago, but I imagine there was some nice wizardry to get old computers to perform so much better than they could as office machines.

Probably still have that driver somewhere, IIRC the driver would install in XP (but only to one of the few NICs in the INF file) but the pro printer app did not have an XP version and even the NT4 version would not install in W2k or Wxp.
Different physicists will have different preferred ways of explaining (interpreting) observations. Given the same observations, competing theories/interpretations/models will arise. How to choose between those that don't conflict with any of the evidence?

A famous scientist, Arthur Eddington, did a lot of work on what he called 'Fundamental Theory', an attempt at unifying everything. It went over 'like a submarine with screendoors'.

After I'd looked through the book for a couple of hours, I asked a seasoned quantum theoretician if there was anything particularly wrong about it. 'No'. Then why hadn't I heard of it, why didn't anyone take it seriously? 'Because they didn't like it.'

> Russia is still more democratic than many of the US’s allies

Russia is an authoritarian dictatorship with the same guy ruling for 21 years and counting. Which allies did you meant?

> and certainly more democratic than it was under Yeltsin

Under Yeltsin they had freedom of speech, freedom of assembly, separation of powers, state-independent business including large corporations, the federation, and independent press. Putin dismantled all of the above.

> a physics paper from China or Soviet Russia would not automatically be regarded as suspect

Russian government was caught cheating with doping tests of athletes: https://en.wikipedia.org/wiki/Doping_in_Russia

Ok sure, but interest is fine.

> "This is why Islam has Zakat laws to ensure the poor are lifted out of poverty."

Charity isn't as good as letting people get access to capital that they can leverage for themselves.

We're not going to agree on this so can probably leave it here.

I will say I think morality exists in spite of religion.

It's not hard to pick out examples where Islam fails on the morality issue, see: women's rights and the recent Charlie Hebdo murders, both driven by ideology.

This is off-topic flame war material though.

Those causal processes still have effects outside those brains does not remove the idea that your brain only exists because of external causal events, and your brain is only reacting to those external causal events. At no point is there a spontaneous reaction that is unpredictable according to the known laws of physics, therefore, you don't have free will.
It sounds like you think that what happened is related to margin accounts. I don't think that is accurate (see the blog post this thread is on).

Robinhood does keep the equivalent of auto insurance, by the way of the deposits they make with the DTC (and probably other measures). So the analogy is that you keep insurance, and you suffer some catastrophic accident due to some crazy driver coming out of nowhere. Are you at fault?

But I do agree that they didn't do their job, with respect to PR / communications. And I agree that this blog post seems designed to mitigate the effects of that.
I know exactly what you mean. It seems there is a lack of such non-insulting-to-the-reader scientific writing: things are either too advanced (FEBE = written for experts, by experts), or to basic and without any scientific content bound a tenuous analogy or two, so it's refreshing when one encounters good non-technical scientific explanations...

Cudos to Miguel F. Morales and arstechnica. Well done!
Show HN:Send Emails from front end web applications
Frontend developers can now send emails from their web applications without the need to setup backend server.
Actually the biggest reason is RH was the first to offer zero commission trading and a very simple UI. That led to a big customer base of new traders. Lots of free marketing by those newcomers on social media and the inertia of switching brokerages kept the flywheel going. This incident was bad enough to make people get over the inertia of switching, others now offer zero commission trading, so RH is going to bleed customers as a result.

The other apps may not be quite as easy to use for someone who has never traded before, but the basics of trading and options have been democratized enough that it is probably no longer enough of a moat.

Email: yuyangchee98@gmail.com

I graduate with a BS in Computer Science in June and am looking for a front end engineering position after.
I'm involved with a research lab in my university as lead engineer in a project called SwingBeats. We design and build devices that are worn on the ankle to teach dancing using vibrations. 2 years of work culminated in two research papers being published, one of which won best technical paper.

For the past few months I have also been working part time at a startup as a front end engineer. As the team is small, I am familiar with many aspects of getting a project to production such as engineering, design, security, and deployment.

I’m now looking for a full time job and can start around July/ August. I qualify for OPT+extension.

Thanks.

I just looked up the CDC data and it says ~0.7% of the US population dies each year. Out of ~330 million people, that's 2.4 million people each year.

So assuming that 400k figure is excess mortality, that means 17% more people died last year than normal.

That is tragic, but the way it gets talked about, you would think we were at 10x or more.

According to the CDC, the total number of deaths caused by Covid is about 6% of the people who died with a positive test result.
You're leaving out the aspect that this was all extremely time sensitive. Those silver posts were no longer relevant to the situation.

This video explains exactly what the hedge funds are doing: https://www.youtube.com/watch?v=gMShFx5rThI

Once the media reports broke saying "Redditors now buying silver!", there was no one on WSB actively discussing buying silver. The more likely story is that the hedge funds researched recent WSB discussion, saw some talk about silver, loaded up on silver futures options, "leaked" a hot new WSB story to their media shills(maybe even providing the same references as you did), and the media ran with it so they could report a "scoop". Loading up on the futures options probably drove the price up, giving more credibility to the fake news story. Then they probably unloaded their long positions and shorted silver since the price was temporarily propped up by the news-watching suckers who ran out and bought it. If you look at the $SLV chart from last week, the price movements would support my hypothesis. They probably did this because they needed short term cash quickly, and wanted to distract from $GME.
I’m sure that it’s just a matter of time before someone somewhere is going to target the author of this post with snide remarks on their qualifications/ignorance and hinting at them being a Telegram shill (I’m not one of those).

That said, I liked this article a lot since it puts things in a manner that focuses on how to approach these comparisons and backs them up with relevant information. Elsewhere, there’s too much of appeal to authority that ignore other points (mainly nuances that are important).

I completely agree with this part:

> A big chunk of the criticism of Telegram amounts to defamation, lies and arguments from authority. Unfortunately this is not an opinion, but a verifiable fact. Even more unfortunate is the fact that many of these come from respected figures of the computer security community.

A few corrections and additions are required in the article:

* The part about Signal not having a standalone desktop client is not true. This was already pointed out in another comment here. Signal has had this for a few years now.

* “This is more subjective than an exact since.” — there’s a typo here for “science”.

* I didn’t see mention of metadata collection by WhatsApp. That’s as important as the content of messages.

You can - on eBay! But prepare to pay $5+/piece (over $10 and even $20 for 3M ones). Meanwhile, supposedly, price gouging was supposed to be persecuted. There are lots of KN95 fakes, by the way. There are tons of KF94 authentic ones on Amazon.
Symbolic execution would tell you whether a page-table could be mangled, and if so which range of input of values would lead to that state. (Though you may need to annotate your code to define what a bad state looks like if it's not something as simple as a NULL pointer dereference.)

But the capacity for achieving that is a function of the engine and how it integrates with the language. Similar to formal verification it's strongly computationally bound in practice, so the best results (e.g. more comprehensive coverage) are achieved when you structure your code in a way that components (functions, groups of functions, etc) can be symbolically executed individually; and when you can drop annotations in the code to narrow down value ranges that the engine can't determine itself within a reasonable amount of time. So in principle a symbolic execution engine could determine whether a page-table could be mangled, but in practice it probably wouldn't be able to definitively tell you one way or another if you simply tossed the entire FreeBSD kernel source code at such an engine.

I'm not particularly knowledgable in this space. I'm abstaining from giving a proper description of what symbolic execution actually is because I'll probably just confuse things. But I have used KLEE and even found bugs using it. It's a steep learning curve so once you get to the point where you can make use of KLEE much of the theory will begin to make sense even if you can't describe it properly ;) And if you've ever used formal verification systems, especially ones with strong language integration, things will make sense much earlier.

I don't think there's a clean dividing line between symbolic execution and static analyzers. Some modern static analysis tests and optimizations in GCC and clang could be described as employing symbolic execution. A proper symbolic execution engine can just perform such tests more comprehensively, exploring much longer, deeper control flow paths with far greater state spaces.
I didn't declare it by fiat. You claimed no system should dictate how you behave, and yet you dictate how a person should behave. Your own argument defeats itself.

"New mental paradigm" means you don't think like you used to. I.E., if you were ever religious, that was one mental paradigm. If you ever lose your religious beliefs, now you have a new mental paradigm to understand the world and operate in it.

As for fixing the prison problem, it absolutely does. It means what we have decided as acceptable public behavior is to be cultivated, and if we can remove the part of your brain that wants to violently subject others your will, we excise it and then you suddenly become a productive member of civilized society again. It's not even your whole being, just a small part of your collection of particles that we annihilate.
This isn’t actually a fault of TS, it’s an explicit goal. They design the type system not to guide usage but to make existing usage explicit and trustworthy.

The places where the type system encourage rabbit holing are almost always where bad types/APIs are already prevalent. Where you’re starting at the type level and don’t have an inclination to allow all manner of dynamic nonsense it’s not that different from types in an ML-family language.

That's probably never going to happen. Galileo's heresy charge was for, among other things, denying the trinity (not his views on how the planets were laid out, as the common myth goes).

That very matter was the cause of some consternation in the early ADs, but it was long settled (to the tune of about 1200 years) by the time of Galileo.

I regret giving away my IMSAI 8080 S-100 box a little over 15 years ago. I should have looked on eBay. If I had, I would have known how collectable they are. I may have been able to get a few hundred bucks for it anyway. It was still in working condition, but all of my (8") boot disks were destroyed by humidity. It booted a few times, but then didn't. While troubleshooting, the disk drive ate all the remaining boot disks.
Then why is my outcome not worse for believing I don't have free will?

You could call it that, but these are obligations that appear to have been unilaterally decided by the DTC without prior notice. As far as I can tell, any brokerage using the DTC could potentially suffer the same fate if the stars aligned.
The stack effect is problematic in HK whereas there are a lot of high-rise apartments.

https://en.wikipedia.org/wiki/Stack_effect

Also, it's been spread via poorly maintained drainage systems.
The (1) and (5) and so on are the section of "the manual" that is being referred to; "the manual" referring to the entire system manual, and the one command you're looking up being just one page in that manual (hence "man page").

As for what those sections are, `man man` tells me (my system gets this man page from the "man-db" project https://www.nongnu.org/man-db/ ; your system may use a man page of different authorship, but it should tell you roughly the same thing):

The table below shows the section numbers of the manual followed
by the types of pages they contain.

1 Executable programs or shell commands
2 System calls (functions provided by the kernel)
3 Library calls (functions within program libraries)
4 Special files (usually found in /dev)
5 File formats and conventions, e.g. /etc/passwd
6 Games
7 Miscellaneous (including macro packages and conventions), e.g. man(7), groff(7)
8 System administration commands (usually only for root)
9 Kernel routines [Non standard]

Sometimes the number has a suffix; for example, the "p" suffix as in (1p) or (3p) indicates that the man page is taken from POSIX (and therefore might be missing features that your version has; but also that everything in it can probably be relied on on other systems). Or (3perl) which indicates that it's a Perl library function instead of a C library function.

You can tell `man` which section you're looking in like `man 5 passwd`. This is useful for looking up passwd(5) which describes the /etc/passwd file, rather than passwd(1) which describes the `passwd` command to change your password. Or `man 2 signal` to describe the "signal" system-call instead of the signal(3p) libc function, or `man 7 signal` to get an overview and listing of signals.
Hmm. Any specific points of concern with the docs at this point?
What do you mean by lab efficacy? These vaccines are using large scale real life clinical trials.
I agree with your general point but take a look at the map on this page: https://admission.princeton.edu/how-apply/admission-statisti...

> How is my subscription secure if authorisation key is made public?

>> Emailyt needs authorisation key to validate your subscription, and the key is only valid when using from the pre-configured website

If this means that they are checking the Referer then of course that’s trivial to spoof. So anyone with CURL can trigger emails to be sent?

Unless it’s a one-time key that’s generated on the backend to send a specific email (e.g. hash verified)... how can it truly be secure?

Since these will be valid emails sent from the authorized domain sender, spoofing would be a big problem.

Is this a Show HN?
How can you claim things that happen inside the human brain have causal influences on things outside the brain and yet at the same time ignore the causal influences the outside world has on the internal brain processes? Information flow is a two way street if it can happen in one direction as far as I am aware. What you seem to not grasp is the idea that external events can influence your behavior.
You completely missed the point. The point is that your approach is self-centered and focused on how you will react to the virus. It’s never been about you, it’s about being a vector of transmission. The more risk you take, the more chance you pass it to someone who can’t handle catching it.

You will likely never see the consequences of that, but you could have transmitted the virus to someone who died.

It’s not a lot to ask for people to refrain from social gatherings and unnecessary activities in order to protect their fellow humans. Do no harm and all that you know...
