algebraic notation != algebra

It can totally be written without "algebra"; it's not the notation that contains the idea, it's only the idea that happens to be often expressed in this notation. I could use any other notation, or even plain English, to express the idea, if I didn't mind the extra verbosity.

For Example:

1. The Berlin Papyrus 6619 (from 2000-1786 BC Egypt) uses prose [1]

2. The Ancient Chinese mathematical text Zhuobi Suanjing uses both prose and a pictorial notation [2]

3. The Baudhāyana Shulbasūtra (from 800-500 BC), a set of mathematical instructions for use in the construction of Vedic fire-altars, uses Sanskrit prose describing geometric constructions using rope [3] [4].

Yes, a common way to design new structures is to 'thread' the sequence onto existing folds.

Rarely, there have been attempts to engineer entirely new folds, although it's not clear how necessary that is.
That's why we are civilised. People value dignity, grovelling for drugs should make one feel shame, and acts as a decent filter for those not desperate.
> The one thing that I have occasionally tripped over...this doesn't seem intuitive.

This paragraph led me to discovering this oddity:

> select 'true' from dual where 3 not in (1, 2, null)
> Empty set (0.00 sec)

That's unexpected, and definitely something that I should be aware of. Thank you.
I took it for years alongside Dexedrine for ADHD, then my insurance stopped covering it and the cost for Provigil was prohibitively expensive (like $1700 a month), so I went off it. I think the patent expired so you can get a generic now, but unfortunately, getting prescribed it again in addition to the Dexedrine has just been more of a pain than it’s seemed worth. I’ve been able to get Nuvigil (very similar chemically and created for the express purpose of extending the modafanil patent) scripts easily, but it legitimately doesn’t work for me, sadly.

Anyway, I feel like I was extremely productive on 400mg of Modafanil a day, and I understand why people have used it for nootropics.

> The decision to take an umbrella shouldn't be about the probability of rain, but about the cost of being rained upon vs the cost of taking an umbrella.

A good example is Seattle and surrounding areas. When I lived in central California, Southern California, and the Bay Area in California I used my umbrella many times a year.

In Seattle and the surrounding areas I've used my umbrella maybe 10 times in the last ~30 years.

Seattle gets much more total rain than those other places, and has many more rainy days, so it might seem odd that I'd use my umbrella much less frequently.

The difference is that in Seattle unless you are obsessive about having your umbrella with you at all times except maybe during the summer, you are going to get caught in the rain without it. After that happens a few times you realize that because most of the time our rain is not very intense you didn't actually get too wet--in the time it took to walk between buildings or between a building and your transportation you only got a little wet.

If that bothers you a hat or a hoodie will take care of it, without the annoyance of having to dedicate a hand to holding an umbrella.

When we do get the intense rain that will get you seriously soaked in a short time it usually only lasts a short time then it is back to the mild rain that your hat can handle.

Those 10 times I used my umbrella here? About half of them were shortly after I moved to here, before I figured out that going around one handed for at least half the year is way more annoying for not really much noticeable gain over getting a hat with a wide enough brim to keep the rain off my glasses.

The other half was recently after I installed gutter guards around my house and garage and made some adjustments to the drainage around the downspouts, and specifically went out during those brief periods of very intense rain to check that the gutter guards could handle the flow and the the water was ending up where it was supposed to end up.
I'd almost suggest reducing the power of flagging on posts even more, but I won't for two reasons:

- This is your job and from everything I see you already put a whole lot of thought into it and I don't think I can outsmart you here.

- IMO things have become better the last decade so it seems to me some adjustments (either technical or in the user base) have already happened. [1]

That said, maybe we as a community could become even better at not flagging things that others enjoy?

I used Modafinil almost daily for a few years. It was amazing at times, and some of my projects' success I can attribute directly to Modafinil. One of the main downsides was (what I assume was?) the lactose they use as a binder (if you get the cheap Indian variant at least) wreaked havoc on my digestive tract.

Over time I started to get panic attacks, culminating in a finaly, massive, life altering experience. I haven't touched it since. I don't think it was soley due to the drug alone--but it almost certainly didn't help.

Modafinil is awesome, but it's not a cure for whatever underlying problem you have.

> I understand this thought process, but in my opinion it's the wrong way to think about software concepts. ... just limits your ideas about what is, in fact, an abstract concept.

There's nothing abstract about language constructs. Learning about a language construct via translation is a perfectly fine way of clarifying its semantics, whereas an "abstract" description can easily be too general and fail to pin down the concept; it can also rely on unstated "rules of the game" for how the abstract construct will operate within the program, that not everyone will understand the same way.
You are too inexperienced to work on the code or understand its context, even if the code is perfect?

Then you are the problem detected by your being unable to absorb what it is doing.
I know this is kind of an obvious follow up to your comment, but, have you been tested for ADHD? You described exactly how my brain reacts to mixed amphetamine salts (AKA Adderall). Caffeine doesn’t really do much for me, either, incidentally.
Wow, that's bad. It seems obvious that something like Alexa would transmit some amount of data not intended for it and that would be listened to by someone for training purposes. And probably enough data that someone remotely privacy conscious would not voluntarily install some 24/7 listening device into their inner sanctum.

But what on earth would posses Alexa to record entire conversations without either piping up ("sorry, I did not understand this request") or figuring out after a few seconds that this was probably a false alarm and turning itself off? How would this be remotely excusable?

How long was the longest recording not really intended for Alexa?

> It's already been here and Dell/HP is still an X86 shop

Yeah, because Dell and HP are enterprise vendors - and as long as there is no ARM Windows version that offers x86 backward compatibility, no enterprises (and frankly, most private customers) will shift to ARM.
Thank you. Whenever I talk about modafinil with someone I always mention the potential skin issues and tell them to try low doses first. I wasn't sure how common it actually is but yours and the other's reports even being here suggests it's worth taking those precautions.

It's is not. Being a fabless designer of hardware IP doesn't make them "basically a SW company".

It's still very much a HW IP company any way you slice it.
Honestly the fact you felt the need to try to answer up the claims by throwing dirt at one single point that they made makes it clearer to me then ever that the claims are true.

Everyone knows that the best pr strategy when your being attacked by someone who's claims appear true to anyone who has their eyes open is to keep quiet and let it pass, instead you blew this up.

I now believe them. Congratulations.
First and foremost would be financial transactions, especially banks, that if these links were lost might be unable to make settlements and reconcile daily balances with overseas subsidiaries, partners, and correspondents. That would have an immediate impact on any business that relies on making or receiving international payments to/from suppliers/customers - think SWIFT [0].

Secondly is the affect on 'cloud' services (AWS, Azure, Goggle) with their complex inter-dependencies across services and geographical regions. We've seen several instances over the last couple of years where even a minor failure in one system has a knock-on effect to tens of thousands of other organisations that rely on it. Also, consider the reliance that AWS globally appears to have on US-East. If AWS Europe data-centers loose their link to US-East there could be major disruption of many services hosted on AWS, even those that use multiple availability zones.

Third would be the knock-on effect of switching to other routes (BGP) and the consequent 'traffic jam' as traffic between North America and Europe attempts to use alternate routes - maybe via Latin America and Africa or Asia.

Fourth, telecommunications ('phone) and VoIP services linking North America and Europe, Africa, and Middle East.

Fifth, and possibly the hardest to mitigate, is the by-product due to extensive use of CDN 'edge' services (Cloudflare, etc.). Most web sites nowadays have many dependencies on externally hosted services. Many are behind CDN edge servers. If the origin servers for those are on the other side of a major break then suddenly services you'd expect to be fully local will break in unexpected ways.

Oh, maybe. I was thinking of 'please refrain from smoking outside the designated area' and similar, I thought it was a (crap) attempt at making the signage politer and less like an order (which of course it was) - but then I was a young naif when designated indoor smoking areas where allowed anyway!

As another 2 data points:

My brother has narcolepsy, and finds modafinil much better than amphetamines. He says he has zero side effects with modafinil, and it makes him much less jittery than amphetamines.

I have CFS, and sometimes need a stimulant if I must stay awake. I've tried amphetamines, but they make me really jittery and a bit anxious and snappy - I feel "tweaked", and it's not pleasant. By contrast, modafinil keeps me focused and awake, with the only side effect being a small increase in blood pressure.

IMO modafinil is a wonderful drug.
As someone who has just gone through the ADHD diagnostic process in the UK - previously abusing stimulants is a risk factor they have to consider before prescribing you anything.

I have previously used Modafinil fairly extensively and considered purchasing Ritalin or Adderall on the dark web, but was very worried about telling the doctor in case it would cause me issues getting treatment.

A Man Who Said No to Wal-Mart (2006)
Mirror deployment was done before insertion, moving the 18 mirrors up from their locked position by 12.5 mm. Now, 3 months of mirror alignment will follow. They will align with a reference star having to first move one mirror a little bit to identify how the mirror affects the alignment, then calculate the alignment and move the mirror. Each mirror's position can be controlled at 10 nm resolution.

That's not very convincing. Why can't a "dog" be a perfectly ordinary data structure that you manipulate the usual way?

while True:
for dog in dogs:
if dog["hungry"] == True:
dog["lastfed"] = time()
dog["hungry"] = False

Okay, I hear you say, but the fact that a dog is an associative array is an implementation detail. Supposing I want to abstract that - don't I need objects then? No! Just define some functions:

while True:
for dog in dogs:
if is_hungry(dog) == True:
update_last_fed(dog)
satiate_dog(dog)

So you end up with an abstract type (dog) and a bunch of functions that operate on that abstract type. Is there any advantage to "gluing" the functions to the data? Well yes, but it's subtle. Imagine you had two types of animal:

while True:
for pet in pets:
if species_of(pet) == "dog":
if is_dog_hungry(pet) == True:
update_last_fed_dogfood(pet)
satiate_dog(pet)
elif species_of(pet) == "canary":
if is_canary_hungry(pet)
...etc etc ad nauseam

With objects, you can make this elegant with pet.satiate() etc. Note however that this problem goes away with multiple dispatch - there's no reason why the language couldn't be designed so that satiate(pet) called different functions contingent on the type of pet. We already do this for math! Adding two floats is mechanically distinct from adding two ints, but it's a rare language that makes the programmer use different functions.

Android tablets are cheaper and consume less power than some free-standing monitors; throw in a keyboard and mouse and the multi-seat cost ceases to make sense.

For the Linux developer use case, where a keyboard (and less so a mouse) is required, multi-seat only makes sense if you are cramming a large number of developers into a small space (which is less desirable during a global pandemic).
> The actual solution is to reduce the cost of enforcing copyright - right now it takes a court case, which obviously is a nonstarter for anyone who isn't making bank off of their copyright.

Making it easier will result in even worse systems than YouTube's insane extralegal "copystrike" process which enables such abuses as police playing copyrighted songs to prevent people from sharing videos of them.

The opposite should happen. It should be much harder to enforce, it should most definitely not be automatic, it should cost copyright holders huge amounts of money, it should require them to go to actual court, there should be severe penalties for fraudulent claims.

> we'll rewind to like 300 years ago when the only people who could afford to create art were born rich or willing to find a rich person who'd individually sponsor them

If we keep going like this we'll rewind about 100 years to the status quo before the invention of computers. We'll have them but they'll be restricted to the point they're equivalent to old mass media. Their potential squandered in the name of keeping old industries alive. Everything the internet was meant to be, destroyed due to the surveillance and control necessary to enforce copyright.
Im also not in love with the shorthand hash syntax, but besides `_1` I cant remember at the moment what new syntax 3.1 have that 2.0 dont. Pattern matching maybe?

But now that I think about it, yeah, even looking only at pattern matching there is a lot of new syntax going on.

Nvidia doesn't licence its designs to other companies for incorporation into their own chip designs, ARM does. That is the main distinction I think, and why people want it to be a neutral third party.

The JWT is famous for costing over 10b USD to develop. AFAIK it's the most expensive object ever to be launched into space.

At this point how can they trust any installers they get from the company?

The risk the manufacturer bundling some "legitimate" remote access tool that won't show up as a virus seems high to me. Once burned twice shy.

Bought a system on Ali Express to save money, the parts don't match what they ordered, it is infected with a virus designed to steal their data and infect executables on any USB device plugged into it to spread the infection. Ali Express says computers with viruses on them aren't against terms of service. They for some reason continue to use the system and try to get it to work.

Having a safety critical system simply stop working is very bad design and should be punished by the relevant regulator. The design of a system has to take in to account the fact that the components are going to time out and do something reasonable for maintenance. In the case of something like a fire sensor there has to be a "replacement required" interval at the end of life where the system still works and the sensors can be swapped out one at a time.
Many of Van Gogh's, when seen in person, are almost more like relief sculptures because of the incredible depth of his strokes. I loved going right to the sides of the frames and looking across the paintings to see how each little valley in his strokes caught the light and cast tiny shadows. I think it's also what adds a lot to the kaleidoscopic feel of his works, alongside his color palettes and stroke work; the extra dimension makes his paintings vibrate with restrained energy in interplay with the surrounding light.

maybe his skynet, but that is way too slow. any other skynet would kill us faster. in split seconds.

though i absolutely love the terminator movies, thats not how it would play out at all.
humans would absolutely get zero chance to fight back. The terminator movies plays out in "human time". Computers, specially a "skynet" would work, move and evolve in split seconds, and distribute whatever human-killer thing around the world in seconds, and we would all be dead.

that the good thing, the day computers take over, we wont get the chance to notice.
