sjburt··on California study begins screening for MDMA-assisted therapy for PTSD
Agreed that they are not a pharmaceutical company, but the Phase 3 trial is being sponsored by MAPS PBC which is the for-profit subsidiary and I assume has some sort of revenue motive.
sjburt··on UN Bans Mercury Satellite Propellants Under New Minamata Treaty Provisions
I think the concern was that some organizations were considering big low-altitude constellations. Once you go below 400km or so the drag increases quite a bit so the idea would be to use near-constant thrust similar to GOCE or SLATS.

And there was at least one vendor (Apollo Fusion) proposing a mercury thruster, although I think they have backed off on that. It would have had about 3x the impulse per volume and 2x the impulse per mass of xenon.

I think banning it now is wise, if any small operators had started using it it would have been hard to block it for a megaconstellation and it was very clear that anything release in VLEO would be coming back into the atmosphere. Right now there are no users so you aren't really penalizing anyone.

sjburt··on The case for induction cooking
I've never understood why we need 4 or 5 burner ranges, possibly with a slight size variations. I really only ever want one high power burner and one simmer burner. A dedicated wok burner sounds like a great addition. Another option would be to abandon the dedicated range entirely, and have a variety of countertop induction units that can be stored away when not in use. I don't think you could sell a home with a kitchen like that but it would be a big win for versatility, especially in small homes.
sjburt··on Toll signs on 101 report your transponder setting
Well, if you are wealthy enough you hire a driver and somehow that counts as a carpool, at least in LA.
sjburt··on Dr. Bronner’s, the Soap Company, Dips into Psychedelics
It used to be even crazier.
sjburt··on Flutter is the most popular cross-platform mobile SDK
"In anger" is an idiomatic usage, meaning something like use for a non-trivial purpose. I think it comes from the military, roughly synonymous with "in combat".
sjburt··on I have never read a business plan or balance sheet
Why does it matter? You are changing the financial picture, probably by an order of magnitude or more. The question should be what the company will look like after the investment, not before.
sjburt··on Words known better by males than females, and vice versa
My guess is that most men would know it as a loom and most women would know it as a type of fabric. I wonder if jacquard fabric is still produced on anything resembling a jacquard loom.
sjburt··on The most backdoor-looking bug I’ve ever seen (2021)
I think it's because Signal and Telegram are the leading non-FAANG, non-SMS options.
sjburt··on Let's Settle This
gin, gift, giraffe, giggle
sjburt··on An Algorithm for Passing Programming Interviews (2020)
Because in the real world you don't know the runtime of the optimal solution, except for certain very well studied and simple problems. At best you might know the runtime of the best published solution. But in many cases your problem isn't something that anyone has studied in that kind of detail and it's going to be on you to determine whether your solution is satisfactory or whether you should go back and improve.
sjburt··on JWST Launch NASA Livestream
It was “to the edge of time itself” which I guess is some kind of reference to the telescope being able to observe the early universe? It seemed kind of cheesy.
sjburt··on Webb flies Ariane 5: watch the launch live on 25 December
There are many people in NASA and around that have made similar arguments.

I think the real reason that they never have a lot of traction, sadly, is that if you propose 3, Congress will give you 2. And then when 2 are over budget, it will get trimmed to one. Better to propose one big mission and get it to the point where it can’t be cut easily.

sjburt··on Gaming on Wayland
I have always been happy with font rendering in GNOME3 under both Wayland and X (I don't think there is any difference). It is maybe not quite as good as MacOS, but it doesn't also have that artificial heaviness that plagued OSX/MacOS for many releases and only seems to have really gone away on Retina screens). It is light years ahead of Windows, which is always bad in confusing ways.

If you have Intel or AMD graphics I think you will be happy with Wayland and Linux.

Nvidia had a politics problem for a long time that is being resolved but the resolution is still on the cutting edge so I would wait a while. XWindows is generally fine.

Dual-GPU laptops with an integrated as well as a discrete GPU seem to still be buggy. Best bet is probably to not use the discrete GPU or plan for the occasional driver update kerfluffle. AMD again is better here.

sjburt··on How a Kalman filter works, in pictures
I think you still need a good grasp of linear algebra and difference equations to identify state variables and correctly set up the “model” or “plant” matrix, this is specific to the system so it can’t be provided by the framework. If you can do this, the rest of the Kalman filter is straightforward and can easily be done in numpy etc.
sjburt··on NES Tetris AI hits 102M points and level 237
They hold one finger over the desired button and the finger roll on the back pushes the controller into the first finger, generating multiple taps faster than you could with a single finger.
sjburt··on Intel Hardware allows activation of test or debug logic at runtime
> Intel recommends that users of affected Intel® Processors update to the latest version provided by the system manufacturer that addresses these issues.

The latest version of what? microcode? BIOS?

sjburt··on Daylight saving time is 'not helpful' and has 'no upsides,' experts say
If we didn't have daylight savings, the sun would rise at 4:30 in the summer. This seems quite unpleasant to me. I would rather have an extra hour of evening light.

Alternatively, if we did DST all year round, the sun would rise at 8:30 in the winter. That also seems unpleasant.

sjburt··on Evidence for European presence in the Americas in AD 1021
First, it was a two-way street. Syphilis, for one, is believed to have originated in the new world and have been brought to Europe post-contact.

But Europe, Asia, and Africa combined was a much bigger population pool, so more opportunities for mutation and transmission leading to more types of infectious diseases.

sjburt··on Meat and mental health: Meat eaters suffer less depression, anxiety
A significant portion appear to be feel threatened by (or at least, intensely concerned by) others' personal dietary habits. Paranoia? Megalomania?
sjburt··on Meterorite chunk crashes into house, bedroom, pillow
It will slow and eventually reach terminal velocity. I don't know if it has enough time/distance to do that before hitting the earth but given the small size I wouldn't be surprised.
sjburt··on I'm sorry
> On behalf of myself as the Executive Director, past and current boards, I’m sorry that we’ve created an environment where maintainers are surprised by their relationship with the .NET Foundation. It will be my and the new board’s number one priority to fix that.

This is the non apology. It's not apologizing for the nature of the relationship that was created, it's apologizing for people being surprised by the nature of the relationship. There's an implication in the statement that the maintainers failed to understand their agreements and that's the real root of the problem.

In terms of the "fix", it's not clear whether the fix is to renegotiate the agreements, or just to make it more clear what the agreements meant (in which case, the harm is not really being addressed).

sjburt··on Masten Space Systems is using Ada and Spark to land on the Moon's south pole [pdf]
I've seen this approach. The wrong thing still gets built, but at least you know why it was built that way.
sjburt··on In software, when an engineer exits the team
I would never badmouth a manager on my way out the door. There's no point to it and anyone I am talking to may or may not be a sympathetic ear; in any case, if they're still there, they still need to work with that individual and it's really no longer my business.

"Dream Opportunity" or "Better Pay" are easy explanations that nobody will question. Best just to leave it at that.

sjburt··on Samoa Scraps Daylight Saving Time
The biologically optimal time moves around. People wake near sunrise. DST keeps sunrise at a more consistent time at the expense of moving sunset around.
sjburt··on MIT study finds Tesla drivers become inattentive when Autopilot is activated
This is how I feel as well (having driven many miles with a Comma), but I have no idea if I represent an average driver or if my perceived attentiveness matches what is really happening.

I do think that it is very easy for me to spend longer looking at a screen or button when the autopilot is driving for me, since there is no immediate penalty (lane line, rumble strips, etc) for looking away.

sjburt··on A solution to Newcomb's paradox
With the one box strategy, 90% of the time you get nothing, 10% of the time you get $1,000,000. With 2 box, 90% of the time you get $1,000, 10% of the time you get $1,001,000.

More importantly, regardless of how good the computer is, the difference is always $1,000. This is the c term in the expressions at the bottom. If the computer is always wrong, with 2 boxes you always get $1,001,000. If the computer is always right, you always get $1,000. And the one box strategy always averages $1,000 less.

sjburt··on I'm not an anti-vaxxer but vaccine passports treat me like I am (anaphylactic)
When (or if) herd immunity is reached (measured by rate of community spread), they can drop the need for vaccine passports. The passports are just there in the meantime while infection rates are high.
sjburt··on I'm not an anti-vaxxer but vaccine passports treat me like I am (anaphylactic)
They have something similar, but in her province the list of allowed exemptions is much stricter[1]. If you have an allergic reaction to one vaccine, they require a second dose using a difference vaccine. The author is unwilling to attempt that.

The problem the government is trying to avoid is doctors who will give out exemptions too broadly. There is a balance to be struck and BC took a harder line.

sjburt··on Banks beware, Amazon and Walmart are cracking the code for finance
Yes and no. In your examples, there card has been sold by an individual merchant and there is not an individual account at a bank for your gift card. There is certainly money in Shell's bank, and a liability on Shell's balance sheet labelled "unused gift cards". If Shell were to go bankrupt, it would be quite difficult for you to recover the gift card balance.

On the other hand, there are "universal gift cards" that work as a debit card and can be used anywhere (that supports that type of debit card). These would require a bank to hold the balance; when the card is used the money would go from that bank to the merchant's bank.
