It doesn't 100% remove the need for a manual clean/vacuum completely, you still have to run over the places it doesn't get - occasionally - and yes obviously it doesn't do raised surfaces, windowsills, stairs or the upper corners of the ceiling... and obviously how much benefit you get depends on your home layout.

We've the exact same model as the article, bought on a sale last year for ~£180, and have been incredibly satisfied. The difference between a once a week/fortnight deeper clean and having it run over every day (before we get up!) has been incredibly obvious. It has also added an... incentive to avoid floor clutter.

Why people use CSV instead of DSV?
It seems that most of the people use CSV instead of DSV. Why?

At least at the first glance, DSV seems to be a much better format. It is equally powerful, but much more cleaner and reliable.

About DSV and DSV-versus-CSV:

* http://www.catb.org/~esr/writings/taoup/html/ch05s02.html#id2901882

* https://en.wikipedia.org/wiki/Delimiter-separated_values

Consider the following table (column - text):

1 - aaa

2 - bbb bbb

3 - ccc, ccc

4 - ddd "ddd"

In CSV: aaa,bbb bbb,"ccc, ccc","ddd ""ddd"""

In DSV: aaa,bbb bbb,ccc\, ccc,ddd "ddd"

A quote from https://wiki.c2.com/?DelimiterSeparatedValues:

> DelimiterSeparatedValues files and CommaSeparatedValues are equally powerful, but the reading and writing algorithms for CSV have to maintain more state than the ones for DSVs, and so different CSV implementations end up implementing slightly different rules. Therefore using DelimiterSeparatedValues is closer to DoTheSimplestThingThatCouldPossiblyWork.

I don't understand what the author mean. I don't see how _"the reading and writing algorithms for CSV have to maintain more state than the ones for DSVs"_ leads to _"and so different CSV implementations end up implementing slightly different rules"_.

Also, are there any DSV editors on the market?

It's actually quite a hard task. You'd have to figure out who - if their name had not been on the credit roll - would have made the difference between the movies being as good as they were and much less good. Talent isn't fungible, and great talent can make all the difference. Great talent still needs to be supported, so that's where the remainder of that credit roll comes in. But the third gaffer likely could have been anybody and the movie would have come out the same.

I find the entire TP meme weird.

I am silently cheering on that shaming, but as memes goes, it is weird to watch it unfold.
I don't think CureVac's technology is the right choice, though we should fund everyone at the same time to scale-up at risk IMHO.

Moderna and BioNTech could scale-up to hundreds of millions of doses by EOY without expanding capacity. If the US and German governmetns really hit the gas, we could expand both companies manufacturing at risk and get to hundreds of millions doses in 6 months. Then, if the clinical trials look good, we already have the material ready to go.

Have you considered that most normal human beings require social interaction with others to maintain mental health. Solitary confinement is considered torture by many for a reason. In addition, digital forms of social interaction are obviously not subsitutes for physical interaction, especially considering the harmful effects social media and dating apps already have on mental health. I definitely wouldn't want to live in a world where Zuckerberg and co. control all my social interaction with others.
A bit condescending, don't you think? Also interesting to consider what the intersection of those conscientious enough to use something like this and heed its advice, and those impulsive enough to engage in panic-hoarding in the first place.

> to make every resulting program worse.

That's the crux of the issue though, isn't it. I'd like to think that the compiler developers are not programming at random, and that the optimisations do improve the compilation of code that only uses defined behaviour.

If the only defined value for a condition is effectively:

if (false) { ... }

surely removing the branch is the best thing to do, regardless of what is inside the braces?

If a language makes it easy to accidentally write if (false) when the programmer was trying to test some real condition, then surely that's a problem with the language, not the compiler.
Irmin: A distributed database written in OCaml
Are you suggesting the entire world work from home and interact only over the internet for the rest of our lives?

No, of course not.

But some people who are especially vulnerable can work from home permanently.

We can permanently crack down on things like cashiers licking their fingers to help them open bags.

I have a compromised immune system. The gross behavior of cashiers is one of my single biggest headaches in life. If we recognized how critical a link they are in transmitting disease and took that threat seriously, I imagine people would generally be healthier.

We also can design public bathrooms without doors so you don't have to touch the handle. Walmart has that mastered.

We also can make it more the standard for public bathrooms to have no-touch technology, such as hand dryers and faucets that are motion activated.

We can permanently move to bowing instead of shaking hands. Several older cultures have such practices.

We can more widely adopt the practice of removing our shoes at the front door when we get home rather than tracking dirt all over the house. There are plenty of cultures that do that.

We can move away from wall-to-wall carpeting in most homes in the US. It is not the norm in other countries.

We can move to passive solar design and away from forced air HVAC systems.

I'm suggesting that this isn't a situation where we need to throw our hands up and just be resigned to it being utterly futile. There are many things we can do to reduce the transmission of disease without simply calling a halt to life. And for a professional scientist to suggest otherwise is basically being alarmist because they are stressed out or because the solutions don't fit their mental models of "just pop a pill" or whatever.

They are boring and a lot of them are basically the purview of what housewives historically did. And no one wants to admit housewives did anything of real value.

American culture acts like homemakers and full-time moms are losers and leeches and not actually contributing anything of real value to the economy. A charitable reading of that is that it's a blind spot and people just don't get it.

A less charitable reading is that it's misogynistic BS rooted in intentionally being disrespectful of women and of the value and importance of "women's work" and that people would literally rather die than admit that women's work has real value on par with what important men do, like doctors and scientists. And to whatever degree that is true, the world can now either get over its crap or die due to clinging to it.

A lot of people may die over that. Change tends to occur one funeral at a time because most people stubbornly cling to their ideas and refuse to change.

This can either be an age of enlightenment or a new dark age.

Ain't no big thing. We're all dust in the wind anyway. But the dark path is not the only option.

How do you test the efficacy if you don't know who you're injecting? Maybe it works really well on a certain population, and reacts harmfully to people with some pre-existing genetic trait or condition. You wouldn't know, because you took a random set of volunteers.

If you're going to counter and say "we'd still do the pre-analysis on the volunteers"... Well, that's what takes time.

With enthusiasm, easy things may be easy to reach despite clunkiness. Reaching more ambitios goals as the hunger grows still depends on basic ux/ergonomics and is greatly enhanced by doing basic usability testing according to well founded protocol.
> Even if the behavior is "undefined" as per standard, that doesn't mean that any compiler should "define" its own interpretation and implementation in a way to make every resulting program worse.

The standard offers no interpretation of any undefined behavior, that's literally what meant by undefined. There is no execution of a program that contains UB that could be considered 'valid' by the standard. The compiler has no choice, it has to define its own interpretation.

I love how everyone wants to talk about masks and hand sanitizer, but not about gloves or good old soap and water. To me, it's a sign of wanting to score internet points more than to actually inform. The best information I've seen so far suggests that SARS-CoV-2 can survive 2-3 hours as aerosol, 2-3 days on some surfaces. You're much more likely to be exposed or to expose others by touching something than by walking around. The "hottest" thing you've been around recently is probably the door handle or the credit-card terminal you touched when you went to buy a year's worth of toilet paper. And what's the surest way to prevent infection via touch? A physical barrier.

People who walk around wearing masks but not gloves are making a fashion statement. People who are serious about the issue (including health-care workers) wear both.

It uses different UI paradigms, doesn't even try to look like native controls let alone use them, and isn't fully system-integrated with the behaviour you'd get from a native app. I just opened, and saw:

* Has an expand/collapse panel on the left, using large icons. Not Mac-ish, very Google though.

* Title bar isn't integrated with the system (eg can't right-click on the filename to access locations.)

* General look and feel uses different controls. For example, the Problems/Output/Debug Console tabs: they aren't rendered like macOS tabs. They're capitalized text, and the UI is completely different.

* Cmd+, to open Preferences opens a tab, not a Preferences dialog. This is text (which is nice, good for a dev environment) but even the headings and collapse/expand controls are custom. There is no UI here that behaves like a Mac app.

I could continue for hours. There's almost _nothing_ in the app that is built in an Apple or macOS-congruent style. Now, it's a good app. Absolutely. But it's not a Mac-ish app.

With a native app, all of these things could be done in just as clean (and very similar in layout) UI, but in a Mac style and with what you, as a Mac user, have grown to expect as Mac app behaviour.

> but you've got to assume that they haven't tested randomly but tested people who have been in touch with known cases

Yes. Well with symptoms etc. So of the people who got tested they are much more likely to test +ve. I agree. Which means real cases are massively more widespread than those tested.

It is believed here in the UK that this has been fairly rife for a while now, but those who got it are not statistically counted anywhere. The real fatality rate is way less than 0.9

This is rubbish. The bug exists in LLVM regardless of whether Rust has its own fork, and you don't even need to use Rust to reproduce it.

Furthermore, using your system (ie. unmodified) LLVM with Rust is supported, and still exhibits this bug.

You can't magically whish vaccine into working. The controls aren't there in order to maximize the delay for when vaccines can be deployed.

A bad batch could essentially equal to purposefully infecting people with the disease, for example.

Ed: i don't see it mentioned explicitly: while young people might reasonably volunteer to be vaccinated and exposed to the virus - we really need to vaccinate the elderly and at risk - who has a high mortality rate. We might get volunteers, but it's still different to sign up for a 50/50 shot at death, than the risk of two weeks of mild flu...

And we probably do need to test for adverse effects in the at risk population too.

> I asked her if she thought it was her responsibility to pay for it. “Of course not; that’s ridiculous!” “Well, that’s why I’m not asking the city to pay for it...”

That's a really dumb argument. I can list a thousand things where I shouldn't pay (all) of it, but I should pay (1/10000) of it as part of having the city pay for it.

You're playing a cheap rhetorical trick, not winning a real debate.
The C standard is quite liberal in its use of undefined behaviour.

Some cases are due to conflicting existing implementation that predated the standard. (Though implementation defined might make more sense?) Some are for performance reasons.

And some are utterly bizarre, like some things that should be syntax errors instead being declared undefined. If memory serves right, that includes eg not closing your string literals. (Thankfully, all implementations I know give you an error message.)

I'm not sure what the the "UK model" is, but schools don't seem to be closed there (are here in Germany) and I can't find good info about mass events being banned. The best term I found for Germany's policy is "flattening the curve", while UK news seem to describe theirs as "herd immunity". Sure, there will be overlap in policy, but wouldn't call it the same model.
What does 'removing a statement' even mean?

C statements aren't translated one-for-one to machine code, so you can't just talk about 'removing a statement'.

In any case, lots of undefined behaviour is in the standard exactly so that the compiler can take advantage of the situation.

That's mostly so that the optimizer's job is simpler.

Eg the compiler can assume that you are checking for null yourself already, so reasoning-by-contradiction it can assume that when an execution path looks like it might access a null pointer, that it means this path is dead code. (And there's lots of dead code around.)

Similarly, the compiler is allowed to assume that loops that have no side-effects terminate. (Or rather, non-terminating loops without side-effects are undefined behaviour. So you can't rely on them to implement a busy wait.) See "C Compilers Disprove Fermat’s Last Theorem" https://blog.regehr.org/archives/140 for more about this.

Seems the source of your "10x" statement is the following report: https://www.maritime-executive.com/article/report-cruise-shi...

That's a report released in 2019, but the subject is 2017 emissions.

Since Jan 1 2020 all vessels are restricted to low sulphur fuel. It used to be up to 3.5% worldwide, now you're only allowed 0.50%. Near EU you were already restricted, seems that was up to 1.5%

Unfortunately, reading the article does point to some bad actions: One cruise company seems to be installing scrubbers. They basically take the SOx out of the exhaust (and then dump it somewhere). This is still really bad for the environment, though it makes it appear you abide by the IMO regulations.

In any case, SOx emissions should be drastically slower since 2020. Also, further reductions should be possible. This as 0.50 SOx fuel didn't really exist; initially the plan was to mix 3.5% and 0.10% to get to 0.50%. Ideally the IMO now restricts everyone to 0.10% as it'll probably take 10 years again before anything like that takes effect.
Looks great until they hit the ELISA (antibody test) which requires pre-existing antibodies for the target. That’s like when you search for your keys under the streetlight when you dropped them in the dark. Anything novel becomes an expensive and slow ordeal (aka, it doesn’t happen in practical use) because you need “test kits” (sound familiar?) ... just imagine your malware detector would only flag code which exactly matched exploits it had seen already.

If they replace ELISA with a nanopore sequencer like Oxford’s MinION then you could detect all the DNA RNA in your breath and feed that data into algorithms like BLASTN. Suddenly you can see viruses no one ever saw, and thousands of them at once. Meta genomics is more sensitive than ELISA because you can see everything and more efficient because you can use the same reagents to test for anything. Then we detect virus everywhere as soon as the sequence is available on NCBI (we had a sequence for CoV-19 two months & four days ago)
