Pretty much any custodian with investment-grade credit ratings will be audited and heavily regulated.

> Worse, these custodians of what is already essentially virtual money are going to be sitting on a huge pile of currency and to guarantee the peg, won't be allowed to do anything with it.

The funds are not held in currency -- the funds are invested in "a collection of low-volatility assets, such as bank deposits and short-term government securities in currencies from stable and reputable central banks."

This feels a lot like all the "experts" saying that baking a dead graphics card in the oven couldn't possibly fix it, even though many individuals have found that it actually works (at least temporarily). I fixed a card this way once, and it didn't stop working before I upgraded to a better card a year later.

> no one lost his or her job

Eh? Both the CSO and CIO lost their jobs over this. They "retired", but that's simply a nice way of saying they were fired.

> no one went to jail

I struggle to see why anyone in this situation should be in jail. They did nothing illegal. At worst, as this report shows, they were woefully incompetent. If there was a person who had maliciously caused deficiencies in their security or knowingly disobeyed relevant regulations, that might be worthy of jailtime. But the moment we start putting people in jail just because they're bad at their jobs... we'd have to imprison half of the country.

This is actually a huge issue with the security industry right now. It is very difficult to find qualified people to fill CISO roles because the general consensus is that their company will be hacked (either from a 0-day or from a long-lasting, hard-to-kill vulnerability that has been present since long before the new CISO arrived), and the CISO will be blamed. As it is, most qualified security practitioners would much rather choose a consulting position where they don't have to worry about being blamed. Now imagine how worse that situation would be if you started threatening every CISO who got hacked not just with being fired and publicly shamed, but with jailtime, too.
I would think it's more secure if it didn't leak which were taken. For example, "Name invalid or already taken, please try another"

Hi, thanks for your work. Regarding: "I’ve listened to this bit many times and I’m pretty sure Tesler says ‘foils’, and I guess he’s using the term in its architecture‐related meaning of “a leaf‐shaped curve formed by the cusping of an arch or circle” — But I welcome any correction from native English speakers."

He surely talks about preparing the "transparency" foils for presenting them using the overhead projectors:

https://en.wikipedia.org/wiki/Transparency_(projection)

"A transparency, also known variously as a viewfoil, foil, or viewgraph"

That's how the presentations were done at that time, using the:

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

The good side was that you were able to prepare the foils before but then annotate any (i.e. write or draw on it) during the presentation, which had its own dynamic -- it could have been a result of the interaction with your viewers -- like while you were answering some question.

The foils were even used in the very talk you transcribed: https://youtu.be/OW-atKrg0T4?t=1295

How many times does it have to be repeated, those stats compare apples and oranges. Luxury, modern, new vehicles driven by statistically more wealthy drivers have a much lower accident rate than most cars. When corrected for these factors Tesla’s safety rating is abysmal.

None of the autopilot accidents affected other people? I guess if by affected you mean fatalities, but 2 of them smashed into tractor trailers, so that definitely affected others. There are multiple reports of Teslas on autopilot running into stationary rescue vehicles as well, thank goodness they haven’t been fatal.
Because you thunk governements having power over currency is a good thing? At least with corporations you can choose to deal or not with them, that's the dream.
> why does everybody say it's a "Facebook currency", a Facebook project, if there are +/- 30 corporations in the association?

Because FB launched it, and currently appears to have the most control over the project. At the same time, people don't actually take the time to understand the governance model.

> Does Facebook have more decision power than Visa, MasterCard or any other participating corporation?

No. They get a seat in the governance organization, which they hope will be about 100 organizations at launch (so they get ~1% of the vote.)

> Or is Facebook simply the main vector Libra will be promoted with?

For now, looks like it.

> Would Libra still be a project if Facebook was (hypothetically) shut down?

Yes, it would. Again FB will have just 1% of the control at launch.
I too would love to see the federal government take a much stronger role in developing strong and effective security standards, but you also have to realize that the congressional subcommittee that created this report specifically has the job of investigating situations like this, and is not intended to be a body that prescribes in-depth solutions. It should be a separate body, one with real security expertise, that does that.

Indeed. I used to work in a business that was peripherally related to the security industry, and the conventional wisdom was that shoplifting was typically either an inside job, or an inside job with a customer as a confederate. Most of the security products (20+ years ago) were oriented towards monitoring employees, such as a gadget that superimposed the register transactions on the security video tape.

That's why big stores have the highest concentration of security cameras above the checkout lanes, exactly where a customer is least likely to try and hide something.

I can attest that's the case here in Indiana.

I usually buy alcohol from Sam's Club, since in Indiana its illegal to put any preconditions on an alcohol license, other than what is required by state law (21, not being drunk, etc). There's even signs over the Sams alcohol aisles stating state law.

The door guards aren't told of this, and will make you think that you must be a member of Sams to even enter the store. My opinion: if they want to maintain exclusivity of a 'walmart', they can ditch the alcohol. Otherwise, follow the law.

Sure it'll be nice to make easy money off the interest on deposits. And it'll be nice to make money on the analytics that can be run on all the worlds' transactions. Great.

But the biggest pay off is that once consumers buy into Libra as a thing on its own, the policy can be changed to no longer link it to any basket of currencies, and it can then be issued without that annoying and expensive currency-buying-thing. Just pure profit.

If you have a machine connected to internet, they have you.
Julia's systems can make use of ChainRules.jl which doesn't assume locally complex analytic, and instead uses its Wirtinger derivatives (df/dz and df/dzbar), and if complex analytic just uses the well-known simplification df/dzbar=0. This allows for non-analytic functions to be used, and you just need to supply all primitives in Wirtinger form. Julia has enough non-ML people using this stuff that complex numbers actually get used here :).

We're not in disagreement. The premise of the article that 80% of Americans live in squalor that isn't present in Europe is designed to convince middle class Americans that they're worse off than middle class people in Europe. Which I don't think is true, or at least, it's not obviously true.

It's hard to contest, however, that the lower 10-20% of people are better off in Europe.

> It's considerable boilerplate

No, it's not boilerplate, it's actually functional. Type declarations in Lisp are optional (because they are there only to improve performance, not to change the semantics of the code).

> > Is that what you want to see, a cleaner syntax for type declarations?

> Of course, that's what I wanna see. Haven't seen it yet.

OK, here is one possibility:

(deftype u8 () '(unsigned-byte 8))
(deftype u32 () '(unsigned-byte 32))
(deftype array-of (type &optional size) `(simple-array ,type ,(or size '(*))))

(defmacro c-defun (name args &body body)
`(defun ,name ,(loop for (var) on args by #'cddr collect var)
(declare ,@(loop for (var type) on args by #'cddr collect `(type ,type ,var))
(optimize (speed 3) (debug 0) (space 0) (safety 0)))
,@body))

(defmacro c-let (vars &body body)
`(let ,(loop for (var nil val) in vars collect (list var val))
(declare ,@(loop for (var type) in vars collect `(type ,type ,var)))
,@body))

Now you can write:

(c-defun update-crc32-checksum (crc u32 buffer (array-of u8) end fixnum)
(c-let ((cur u32 (logxor crc #xffffffff))
(table (array-of u32 256) (get-crc-table)))
(dotimes (i end)
(c-let ((index u8 (logand #xff (logxor cur (aref buffer i)))))
(setq cur (logxor (aref table index) (ash cur -8)))))
(logxor cur #xffffffff)))

Better?

I didn't say it was better to write this code in Lisp. I said it was easier to make this kind of change in Lisp if you want to.

Okay, I did and I was able to compile the `vc` compiler from the C source. The REPL in `vc` seems to work (at least for the basic printing I tried) and running `./vc -o v .` worked as well. But the new `v` compiler segfaults with:

coudlnt create file "/var/tmp/vlang0.0.12//vrepl.v"
Segmentation fault (core dumped)

EDIT: however, if I understand it correctly, it was not the instructions after all, that resulted in everyone having segfaults...

EDIT2: okay, so I redownloaded the whole thing and yes, you fixed that now. But it still segfaults sometimes. For example if I try to pass a `-h` flag.

This is quite possibly an uninformed question, but is it possible to use multiple allocator implementations simultaneously in the same program?

Obviously this would introduce additional creative ways in which to mess up memory management, but at least theoretically it seems like it ought to be doable.

PII or not, companies are still going to be hacked. PII isn't even amongst the most valuable types of data that attackers are after, nor is it the most damaging type of data for a company to lose.

It should be hard to fill CISO roles because companies should have high standards and should be looking for the best of the best to fill those roles. But that's not what I'm talking about. There is a decent sized pool of qualified security practitioners that could be CISOs, but none of them want to be because the current way things work is that they will inevitably get fired and shamed for something that they had little control over. That's not good for them, and it's not good for us, because you know what's worse than a company having a lot of insecure PII? A company that has a lot of insecure PII that also doesn't have a CISO.
For the same reason it is a hard thing for Microsoft to run 16bit apps alongside 64bit apps even though Wine shows that it is perfectly possible for the vast majority of them (those that could run under 16bit protected mode Windows 3.x, which is pretty much all of them): it isn't really a matter of it being hard, it is more a matter of them not wanting to bother (or "allocate the resources to do so" in corporatespeak).

Diffraction limit for visible light would imply a rather huge aperture to be able to resolve 1cm on the ground from a low orbit. One that would stretch credulity. I would guess 5cm is achievable. Commercial applications are limited to 40ish cm. When I worked in aerial surveys we were working with an 8cm ground resolution, this was a good trade off point for wide field of view, motion blur, exposure, resolution and camera cost. So you can do a lot better for much cheaper with a plane (drones included). Plus you can fly under clouds and it is easy to change where you want images.
