A 32-wide SIMD core executing 16 or 8 or 1-thread at a time is just SIMD execution that's running at 50%, 25%, or 3% utilization.

See figure 22 and figure 23 in: https://images.nvidia.com/content/volta-architecture/pdf/vol...

Thread divergence is bad: very very bad. Running 2x, 4x, or 32x slower (or less parallel technically). You want to avoid those situations as much as possible.

What NVidia noticed is that thread divergence is necessary for many classical locking algorithms: where serialized code must execute one-at-a-time to run an algorithm correctly. Under these conditions, tracking the instruction pointer, and turning off 97% of your cores to execute 1-at-a-time (instead of 32-at-a-time SIMD) is done.

That's WHY __syncwarp() exists, so that you can return to 32-at-a-time execution as soon as possible. Its not always possible for the compiler to figure it out, so the programmer can put a __syncwarp() as a compiler hint that 32-at-a-time is safe again.

The Joy of Watching Other People Clean
Learning about informal fallacies is useful for a couple of good reasons and one bad reason:

- They help people to understand why a superficially appealing argument might not be a good argument. It's a useful innoculation against bullshit. Someone who has internalized informal fallacies can use them to spot bad arguments in the media or from politicians, for example.

- They help people to avoid using falacious arguments in their own conversations. If a person wants to make a strong case for a position, at work for example, they're more likely to be taken seriously if they avoid bad reasoning.

The harmful motivation for someone to be interested in a list like this is that they're effective rhetorical strategies when used with the right audience. If you're interested in persuading people and you aren't very moral, fallacies can be your friend.
Yes, I totally agree with that being a problem. At the end of the day different UIs satisfy the goals of different people. It's a bit pointless to bash people for picking things that fit their lifestyle.
What is the environment you listen in (do you need noise cancellation or would isolation be enough)?

Would you be using them on your laptop or desktop (eg Logitech webcams usually have decent mics)?

Do they really need to be headphones or would on-ear/around-ear headsets work too?

I generally have a problem in that all headphones fall out of my ears (there's a pair of foam Shure's that don't as much, but they were like $100 for a wired no-mic headphones, and I usually pair them with a Logitech c930e extra wide angle webcam).

I've recently gotten the much lauded Sony WH-1000XM4, but they are very warm on your ears and you look funny, but per reviews, they are the go-to choice for exactly calls + music + travel (hopefully some day soon, right?). At least they don't fall off my head :)

When at my desk, I still hope to resolve my shotgun mic picking up sounds from the speakers pointing away, but I'll probably need to pad my walls to stop the sound reflecting of walls and sloped ceiling. A man can dream, though!
Amazon created or published some very good mobile games for the fire ecosystem way back in like 2013 or earlier. They also had a prime benefit called "actually free" games for fire that effectively gave you a unlimited currency in some free to play games, as well as free access to some paid games.

Both of those initiatives were quite nice and improved my view of the prime program. I do wonder what an alternate time line looks like where they had focused on mobile gaming and creating a subscription gaming experience rather than first party stuff.
I had a bunch of BTC back in 2010 or so. I always used it, my rationale being "I want a future in which we use cryptocurrency, and using it is the way to help bring that future about".

Unfortunately, that wasn't enough, and in retrospect I should have bought $100 of it to hold, but I don't regret not just HODLing back then. The times were different.

I prefer Macports and macOS over Linux package managers because Macports is like a rolling-release package archive without the disadvantages of rolling release on Linux. On Linux, I can use Arch and have the latest of all software - which means I have the disadvantage of having to stay up-to-date on things like dhcpcd and systemd and coreutils. I don't want to have the latest versions of these things or spend time routinely upgrading them piecemeal.

Or I can use Debian stable and everything is stable, but if I want something new I have to compile it myself, or hope there's a backport.

With macOS and Macports I get a stable base system that Apple keeps up-to-date security-wise with monolithic updates that I don't have to worry about, and Macports has the latest for things like Emacs or even the GNU coreutils.

I think that the IB CEO really fucked up there by not, and I apologize if this sounds offensive, dumbing his explanation down more and being a bit more clear.

> the financial viability of intermediaries and the clearing house

These are not the "big players" that WSB seems to think they are screweing. IB doesn't give a shit about a couple of hedge funds (who most likely are not in the game any more anyways). They likely don't care much about any market makers who have found themselves in a bind (I doubt many of these exist though).

Intermediaries and clearing houses are the people who's job it is to ensure smooth operations in the market and make sure that trades eventually settle. Ie, if I sell you something (lets say, 1 GME) for $400, that doesn't happen instantaneously, even though we like to pretend it does. If GME goes to $20, it's possible that the person who bought the thing from me just... never shows up with that $400 (maybe their broker went insolvent, who knows, it doesn't really matter). But it's still owed to me, and now someone in the middle is on the hook. And really, this is a correlated risk. If it happens with 1 share of GME, it's much more likely to happen for millions of GME. So now your clearing house is out hundreds of millions -> billions of dollars[0], and are left holding a couple M in GME stock that they can't sell.

There is a difference between trying to protect a specific player or group of players in the game, and making an attempt to protect the infrastructure that makes the game possible.

[0] And if the clearing house can't handle this, then it falls to your broker, who also probably can't handle it[1]. So then if you don't get the money for what you sold, any sort of faith in the financial system evaporates. Which triggers a bank run. Which triggers a financial crisis way beyond anything seen in 2008 because all of the infrastructure was totally destroyed and now we have to start from scratch.

[1] This is especially true in the case of Robinhood, who I am certain (without evidence) has an extremely disproprotional and correlated exposure to specific high risk tickers (GME, AMC, BB, NAKD, etc)
We see a lot of success from Amazon, but they pump out duds at about the same rate. Remember their phone fiasco? (https://en.m.wikipedia.org/wiki/Fire_Phone)

Overall I think Amazon’s products offer mediocre design and execution except for the convenience factor - their successful products manage to be much more convenient than competitor’s. Especially when the end product can leverage the stronger aspects of Amazon’s business model. Take Kindle for example — Kindle has mediocre UX compared to eg iPad, but is much much cheaper (leveraging that supply chain), and has a more convenient store (again leveraging the OG book business).

When it comes to video games, there’s very little convenience advantage on Amazon’s side, and very little way to leverage Amazon’s existing business to improve the product experience for end user.

Like in other areas, I’m sure if Amazon keeps plowing billions into video games they’ll eventually build an expertise — I just wonder if the company has the patience, or if this area will go the way of the Fire Phone.
Using a mouse heavily for the first 2 years of my career gave me the beginnings of carpal-tunnel syndrome. Switching to a 60% keyboard and carefully choosing keyboard shortcuts for everything has meant I've not had a problem since then.

But where did you get this measure of the population from? I'm skeptical that "population of software engineers I'm familiar with" is equal to "total universe of software engineers."

Similar for platforms that let you build ecommerce sites, like Shopify, Squarespace, Wix, etc. They might be cookie cutter and usually over-priced for the level of hosting you get and the poorness of the wysiwyg site editing experience, but they solve a big problem of letting you get up and running with a trustworthy site fast.

It’s interesting though because there still are plenty of scam sites hosted by those platforms, plenty of dark patterns on Amazon too.

That's a good way of verbalizing how I've felt with the last few iterations of macOS as well as Homebrew's perpetually changing behavior. Most of it feels like change for the sake of change. I've also used FreeBSD for several years, and it's the opposite approach - everything that used to work still does, and things are well-documented. Usually the man page is enough, or the FreeBSD handbook.

Hey, I’m a founder of Nextjournal and one of the authors of clojure-mode.

Highly recommend checking out CodeMirror 6 [1], it’s really well done. On of the main benefits is its blazingly fast incremental parsing system called lezer [2], which is heavily influenced by tree-sitter. The Clojure grammar file is at [3].

I’ve done a small video about this at launch [4] and you can also play with this on Nextjournal [5].

Let me know if you have questions or feedback.

Ahh, very satisfying to learn the name of this property.

It’s especially important in data tables when coupled with tabular numbers (essentially mono spaced numbers) so you can e.g. bold a cell without having the thousands or decimal separators get out of alignment in a column of numbers. Spreadsheet programs use fonts with this property.
Thank you for listening!

I'm just telling you about my experience. Obviously Nyxt is very different from more conventional browsers. I'm an Emacs and StumpWM user, and I'd love to have the same kind of power in browser environment. But without easily accessible docs it's just a little bit too high barrier for me.

> it would drift from different versions people were using

Good point. Maybe as a first step just copy that paragraph from readme file to a more prominent place on site? It's very unusual for a project site to have no manual.

Then make the latest version of docs available online. It should be clear 1) what version it talks about, 2) how to check version of user's installation, and 3) how to open the embedded help.

Then if really needed add docs for previous versions, like some projects do. For instance https://www.postgresql.org/docs/current/index.html.

I suppose at least some basic concepts have been stable enough to not change anytime soon?

Or does Nyxt still change substantially from the UX point of view?
I just realized why I am bad at them. I play defensively, like clearing all the enemies then move on. This is much harder than move fast hit everything and you will be fine.(at least Zelda and Mario Galaxy are like that)

Amps * Volts is power. Power is a proxy (a moderately good one) for air movement (a mix of volume/mass at a specific [back-]pressure).

It’s not likely that a silent 2W fan will move a similar amount of air as the stock 14W fans. The enterprise gear from HPE is pretty well engineered; I’m skeptical that they over-designed the fans by a 7x factor.

Operating voltage tells you “this fan won’t burn up when you plug it in”. It doesn’t tell you “will keep the components cool”.

> You claimed that SASS was a SIMD instruction set, which is false.

Well, they execute 32-at-a-time SIMD, do they not?

There are tricks to split up the execution mask and execute 1-at-a-time, 2-at-a-time, 4, 8, 16, or 31 at a time based on if-statements or thread-locks or whatever. But a "SASS" instruction of "R1 = R2 + R3" is implicitly executed across a 32-wide warp if its execution mask is set as such.

----------

EDIT:

Lets put it this way: If you see a "SASS" assembly for R1 = R2 + R3 in isolation, how many adds take place on that clock tick?

Somewhere between 1 add, and 32-adds. No more than 32-at-a-time. Seems pretty SIMD to me.
Yes. The application's executable is not writeable to the app. You need to go through the package installer. This requires a system controlled prompt for the user to confirm an installation, and requires a seperate permission to even ask which is not allowed for third party apps published to the play store (https://developer.android.com/reference/android/Manifest.per...).

> As a hacker, it's particularly frustrating to feel at the whims of someone else.

Isn't this the very definition of what a hacker is - somebody who finds creative ways to get things done with systems they didn't create and don't control. If you are pushing the boundaries of a system, you have to expect that sometimes the underlying system stop supporting you

A guarantee that the system you're "hacking" on will always continue to support your customizations in perpetuity as it updates seems to me to be the opposite of the hacker ethos. That's not hacking, that's using a system in a supported manner.

> If a programmer who happens to do music production or art as hobby for example, which do you think he would choose, a Macbook or a Linux laptop?

Don't the vast majority of companies have clauses in contracts that say whatever you create on your particular work laptop belongs to the company? I certainly have that in my contract.

In general, I would say that you're getting your work laptop for work. Work-related things should have a priority from hobbies. Having to have a VM for various thing is a strange trade off when you say the upside is producing music as a hobby.
I think it’s misleading to view a currency’s price “stability” as some intrinsic quality that determines whether or not it is suitable for broad adoption. Wild price fluctuations are a consequence of incomplete adoption, relative to the quote currency. Higher adoption leads to less fluctuation as the demand is more constant from day to day.

If we judged the stability of a currency by its supply stability, then Bitcoin would be the most stable currency ever to exist. But for now, it must compete with sovereign fiat currencies and everything is priced in those currencies, so it will appear extremely unstable and perhaps unusable for most transactions.

From very far.

Quartz Composer is a graph of filers that you can interconnect in a graphical interface. You use it to create visual filters or generators. iTunes was using Quartz composer files .qtz for some of his music visualizers.

Quartz Composer is GPU accelerated thanks to its use of the Quartz API.

It was very popular with artists because of the creative freedom it gave when composing the filters. You did not need to be a developer to create a filter, thanks to the editing application.

Quartz Composer is now deprecated and dying in slow and anonymous death.

XQuartz is a windowing system accelerated with Quartz. The X system was not invented by Apple but very popular on top of Unix.
That is one approach. Give them a locked down, with no root access, Windows or Linux box and a company Blackberry. It's not unreasonable for scenarios where the highest security is needed.
