Around 1988, I added phase shift to my optical thin film design program written in Excel 4.0 for the Mac. At the time, this was utterly unique: each spreadsheet row represented a layer and the matrices describing each layer could be calculated right in that row by squashing them down horizontally. The S- and P-polarization matrices could be recorded this way, and the running matrix products similarly maintained. Finally, using a simple one input table, the reflectance of a typically 25-31 layer laser mirror could be calculated. And in less than a second on a 20 MHz 68020 (?) Mac II for about 50 wavelengths. The best part were the graphics which were instantaneous, beautiful, publishable, and pasteable into customer quotations. Semi-technical people could be trained to use the whole thing.

Now about the phase shift. In 1988, atan2 didn’t exist. Anywhere. Not in FORTRAN, Basic, Excel, or a C library. I’m sure phase shift calculators implemented it, each working alone. For us, it was critical. You see we actually cared not about the phase shift, but its second derivative, the group delay dispersion. This was the beginning of the femtosecond laser era, and people needed to check whether these broadband laser pulses would be inadvertently stretched by reflection off or transmission through the mirror coating. So atan2, the QUADRANT-PRESERVING arc tangent, is required for a continuous,differential phase function. An Excel function macro did this, with IF statements correcting the quadrant. And the irony of all this?

I CALLED it atan2.

"Responsible" performance of a role in an organization doesn't put one above judgement for one's actions, at all, which may, though correct from a very narrow perspective, be horrible. The most obvious & crystal-clear examples would Godwin the thread, but I trust the idea's simple enough not to need illustration by example.
The point would be that every time you see a tick, you could be 76-92% less worried.
As dramatic as line closures are, the impact to commuters can be minimized if the transit agency supplies shuttlebusses servicing the line in its place. When LA metro closed substantial sections of the Expo and Blue lines a few years ago, the shuttle routing only added a few extra minutes to commuters trips along those corridors.

Not intending to comment on your broader point, I'm just amused at remembering a story that hit HN last month about a French woman who was accidentally (or possibly maliciously) declared legally dead, and has unsuccessfully spent five years attempting to convince the bureaucracy that she is alive: https://www.theguardian.com/lifeandstyle/2021/jul/03/they-sa...
I've been trying to talk privacy with people for a while. Some folks see targeted advertising as "good" because it introduces them to new products or services. To some milquetoast person with nothing "special" going on in life that's just fine, however, if you are involved in anything that you don't want the average Tom, Dick, or Harry to know about then you're fighting an up-hill battle against a monster that you can't really see but from a distance.

To me, in the United States, there are two major camps of thought:

* Targeted advertising is useful to me and I don't mind someone knowing everything about me

* Targeted advertising is dangerous to me for x, y, and z reason

A world that allows both is optimal. Allow companies to collect data, but have federal agency oversight and requirements up to and including the right to be forgotten. It should be possible to pull a level and dump most (if not all) collected data associated with you.
> Global health leaders including Tedros Adhanom Ghebreyesus, director-general of the World Health Organization, have pleaded with developed countries not to administer boosters given that most of the world’s population hasn’t received even a single dose. [1]

> U.S regulators authorized a third dose of COVID-19 vaccines by Pfizer Inc (PFE.N)-BioNTech and Moderna Inc (MRNA.O) on Friday for people with compromised immune systems who are likely to have weaker protection from the two-dose regimens. [2]

> "It will be a patient's attestation, and there will be no requirement for proof or prescription or a recommendation from an individual's healthcare provider," CDC official Dr. Amanda Cohn said [2]

Clearly we are facing a supply shortage and distribution problem with the vaccines - and citizens of wealthier & more developed countries will fare better given the dynamics playing out. Perhaps that's just the status quo, not sure why I'm even surprised at this point.

For the poor and rural populations in less developing countries, we really need to be pursuing early treatment using combinations of existing and widely available medicines, which have been shown to be very effective at preventing hospitalization and death [3][4] - it's what many front line doctors are already doing anyway, just without the same level of press coverage that vaccines are getting.

The question is simple, does the benefit of using said vaccine or medication outweigh the risk of not using it. In the case of covid being sick for a couple of days and a guarantee of preventing future death is better than a resulting death had the user not taken it.

I would say a couple of days of flu is vastly better than some of the other side effects I've seen with other medications. Take for instance:

- Suicidal thoughts
- Abnormal heart rhythms
- Internal bleeding
- Cancer

At the end of the day, we rely on medical professionals to help us with these decisions and weigh the treatment of said ailments against the side effects we may incur if we do or don't take treatment. For what it's worth I've seen the opposite, most folks took the day off just in case there was a side effect, but ultimately everyone was fine. I know I scheduled my vaccine shots for a Thursday so I could have a 3 day weekend assuming I wasn't feeling ill, and I felt fine so I enjoyed my 3 day weekend.
For a time in 2020, Zoom for whatever reason had a significant boom of popularity (I suppose they had some freemium option for group calls? I really don't know).

As a result, a lot of companies bought licenses because Zoom was the cool tech at the time. My company did this, despite there being an official mandate that all official communication/calls must go through Teams the year prior†.

I think the persistence of Zoom is just whatever the tech equivalent of a hangover is. Everyone binged on Zoom in 2020, and now that we're far more comfortable with work from home and have more stable setups, a lot of places are stuck with Zoom licenses. Embarrassingly, our company's periodic all-hand-calls still are on Zoom when every other operation is done on Teams. I think our brand team also decided to host a few presentations on Zoom when we presented in the US for the sole reason of "well, it's cool."

† I have no love for Teams to be clear, it's awful software. I do understand IT's mandate though, since the entire point of the mandate was to get people to stop installing random stuff on their work computers, which turned out to be a great idea when it comes to Zoom.
I did something similar for tanh once, though I found I could get to 1 ulp.

Part of the motivation was that I could get 10x faster than libc. However, I then tried on my FreeBSD and could only get 4x faster. After a lot of head scratching and puzzling it turned out there was a bug in the version of libc on my linux box that slowed things down. It kind of took the wind out of the achievement, but it was still a great learning experience.
Just replace the /j/ in the URL of the page with /wc/join/, and you should be in the zoom web client.

>You'll asymptote, so you'll stop at the point where the marginal benefit of an additional shot is less than the marginal financial cost, marginal opportunity cost and marginal cost of side effects all combined.

But this is already the case for young people and people who already had covid and recovered, but we don't see them excluded from vaccinations based on their risk profile. So I think there is no reason to think that this logic will be applied more truthfully at some arbitrary time in future.

So you have no evidence of your claim.

>, I’m not confusing prevalence with clarity

...but you do that right here:

>American media (movies, news, etc.) is universal. People all around the world watch American shows and movies and are accustomed to the accent.

So it is prevalence and not clarity.
With cross-site cookies, adnetwork.com has full information about what sites you've visited (among sites that incorporate their cookies). This isn't good either! But generally speaking, an individual site using adnetwork.com for advertising won't have or want access to that vector of your interests; many site operators don't even have visibility into what ads win real-time bidding, just that they're receiving money for providing their inventory. Certainly there are players that can provide demographic targeting metadata to site operators, but to my knowledge they are less widely known and certainly not cheap, and I imagine (or hope) any players with wide enough cookie reach would be discouraged from maintaining a database that could associate metadata with PII.

With FLoC, though, the idea was that the browser would provide document.interestCohort() and the individual site's JS could react accordingly: https://github.com/WICG/floc . This means that any site, regardless of its contracts with ad networks, could immediately identify your cohort and associate it with your activity. Web developers working in good faith would be encouraged to have user.cohort or user.topic fields from day one "just so you have it" - imagine all the ways someone could use this in bad faith. Inevitably this data would leak (or be intentionally leaked) and could trivially become a target list for doxxing closeted people. It's a dangerous, dangerous proposal.
It's probably easier for various teams not to break things, and it provides a more widely known environment (the browser essentially) to ensure that new hires can be pretty productive.

I definitely miss native apps, but I understand why they're less common now.

> The UI, the up-voting process, the very (lack of) structure in how comments are displayed and sorted all encourage verbal vomit, and that's exactly what YouTube gets. In general, social media structure usually provides zero incentives to engage in real discussions and deep thinking. I don't see this being addressed, let alone changed, no matter what the executives say.

I think you might be literally the first person I've ever encountered who has touched on this, whereas, whenever I mention the possibility, any response I get is disagreement or negative. Very often, people "know" that it is not the problem, yet oddly have a very strong aversion to sharing how it is they know that.

I think it would be kind of hilarious if this was in fact (but unknown) one of the root causes of our problems, but no one has the ability to even consider the idea.
> Unfortunately it is expensive, and you can't just buy it and use it, you have to renew the license annually.

Not even that. If you want it for a web page you have to pay in blocks of page views. In my mind that moves it from "eh" to "LOL no". These are licensing terms for people who want the name.
Fantastic work on SerenityOS and great videos explaining your progress. My main complaint is that you are solving many of the same problems that Haiku is also struggling with (such as slow git checkout speed) while building a '90's era C++ based operating system. There's a good chance that your little OS may beat ours in the end. You could have built a great C++ OS on top of Haiku instead but you went your own way with SerenityOS which is valid. You may have gotten discouraged by the sometimes thorny Haiku community development process anyway.

As a French, the Amerian accent is usually the easiest to understand. That's also what most people around me think, though they also think of the British accent as more "fancy". This is for the "American you hear on TV" accent. which is also the one that I hear the most on Youtube or sites like that.

You're right about clarity not being a function of accent, at least not totally. There are some people that speak terrible English with a French accent, and others that speak clear and easy to understand English with a French accent. The same applies to pretty much every accent. I also agree with you on the soft power, however part of the soft power will mean that people are more used to the NA accent.

As a final point, I've heard multiple times that sometimes people that speak English as a second language can understand each other really well while Americans have a really hard time understanding them. If that's a real phenomenon, then having a non-American accent could be detrimental if you want to work in the USA.
This sounds like it resonates with Ted Kaczynski's thesis.

"the internet never forgets things" is more of an caution than a promise.

Don't say stupid things that will look even worse in 10 years or sometimes fairly mainstream things that will look terrible in 40 years, because the internet never forgets.

But, you still need to archive stuff you want to reference later. Even if it's still out there, it might be much harder to find.

Please don’t spread this FUD. The side effects are rare and reversible by stopping the medicine. The checks are also required to check for other STIs.
Mmmh... these are not very convincing examples.

Statically typed languages give you u8/i8 types of numbers.

Maybe having a non empty string, or non empty list, type is useful now and then, but in practice, just have your code work just as well on both empty and non empty values, and you're good to go.

I'm pretty happy with the languages we have today overall (Kotlin and Rust at the top, but C#, Swift, and Java get an honorable mention).
I think I'm done with HN. It has become like a hivemind, it's absolutely impossible to say anything contrarian about the vaccines and COVID in general.

>And how long as the open web survived?

Since its birth, clearly. No matter how you try and spin this, advertising is not a requite for a free and open Web. If ads were to disappear tomorrow, web sites which society has deemed important will survive, the others (if income was necessary in the first place) will indeed perish. And we will be just fine.

Why?
This battery farm, has a capacity of 900 MWh. While a typical nuclear power plant has a capacity of ~3000MW. So this battery farm is just... tiny.

But solar power generation has a large potential for larger capacity, the shortest leg is energy storage.

So if something else can be used for base load (e.g., nuclear, natural gas, hydro), solar power works well for daytime peaks.

No. But it's just a demo.

In perfect conditions if you run it 100 times this is the result.

In the real world they have no application as they fail pretty much always in real conditions. But this is research, pushing things in controlled conditions help you learn what you can do in less controlled conditions. Though sometimes it's just a deadend.

The exact same thing is true of YouTuber stunt videos. Any very impressive stunt was failed hundreds of times but they show you the footage where they pulled it off. The thing to remember is that media is largely fake or deceiving, presenting the very best and not the reality.
