And you have to get the restaurants to sign up, which requires marketing/sales.

It does seem like the sort of thing where someone could develop the app/framework and either focus on some specific lucrative markets (denser areas of higher income cities) and/or have some sort of franchise model.

Very few people do a significant amount of take out delivery when they're traveling. So long as you have a profitable business in a city, there's no particular network advantage (other than any economies of scale) to serving other cities.

This sounds exactly like what's happening in America today. Bring jobs back to the country, which elevates wages due to low unemployment, high worker demand. Bring manufacturing back to the country, which causes better products by them being designed closer to the people who would consume/use them.

Build something simple, and make it a product/tool that doesn't require many active users to work, aka, doesn't require a network effect.

> If it's really common for everything to become a performance bottleneck, it's worth profiling from the start so that you avoid having major pitfalls anywhere. If it's rare and exceptional, FFI for those cases is fine.

You can have it both way, code evolve. It is pretty common in performance critical code that a minor, almost never call function in one scenario, become a performance critical bottleneck in an other. If you already played with large scaled simulation software, this happened almost every week depending of your inputs on what you are interested to simulate.

> On the contrary. Plenty of people do those kind of things in, say, Java. They require knowing about compiler internals and using unsupported hints, or even bypassing parts of the compiler

No it's not again. I have been developing in C++ for 15 years, including in the HPC world and I (close to) never had to touch a compiler internal.
The language gives you what you need for performances, you do not need to play with that.

At the opposite JIT compilers like V8 or Java are monster of complexity very sensible to side effect [1] and controlling things like "Does this data fit in my L2 cache ?" in them is close to impossible because even things like "Where are my data and what are there size ?" is an hard question.

Once again, there is theory and there is practice.

Theory is what you say. Practice is that 98% of performance critical software in HPC, game industry, physics and High Frequency Trading is in C++/C (maybe Rust soon). And this is why.

It's going to go on until someone finally decouples the delivery from the discovery of the restaurants. Right now monopolies have the advantage because people don't go to restaurants and check if they have a delivery app, but people use delivery apps to see what restaurants are available.

If ever there was a killer app for the semantic web it would be a delivery API. It's not going to happen because none of the parties involved have both the motivation and capability to pull it off, but one can dream.

- Make things that solve problems you have.

- Make things that seem interesting/fun to you.

Borrowing ideas from other people seems unlikely to be very engaging, and making things just to learn skills has the same problem.

Lacking side project ideas seems kind of incomprehensible to me, as I have far more ideas than I could ever put into practice, even if I didn't need to work for a living. Therefore, I suspect you do have suitable ideas, but maybe aren't recognising them as such for some reason?

Scripting repetitive or annoying things is an easy place to start. Maybe start with simple website-improver GreaseMonkey scripts, to fix things that bug you, or make your life easier?

The national daily death rate has been trending down since the peak on April 21. If we're going to compare absolute values across all time like this, then we might as well include the 90 billion or so people that have died at some point in human history for comparison (about 100 billion people total, with around 7 billion currently living[1]).

From the 60+ page MacRumours forum thread about the issue, a lot of people don't have the issue at all in clamshell mode (even without the SwitchResX hackery).

My understanding of the issue is that the card has variable memory clocks to save power. However, to avoid visual distortion/tearing, the clocks can only be changed during the monitor's v-blank. However, when you have multiple monitors, presumably you would need extra circuitry or at least some mechanism ensure each monitor is in sync, or to detect when the blanking intervals match when using monitors with different refresh rates. I don't have a strong knowledge of this sort of thing, so I don't know how exactly this is achieved, but in this case AMD has "solved" the problem by simply running the memory clocks at full tilt 100% of the time, thereby avoiding the need to precisely time changes in speed.
SAS, in Cary NC, also has a hotel on campus. The only other options require crossing a busy 6+ lane street where pedestrians are uncommon.
Some platforms ban restaurants who offer a different (higher) price on the platform than they do direct. The problem is that that these platforms flush with VC cash have forced themselves into the market as intermediaries, hoping that they can drive out direct ordering and hold the restaurants to ransom. But food delivery existed long before Deliveroo et al and I always try to order direct when I can. Sure it's not as slick as using an app, but the true price of the app is the long-term viability of my favourite takeaway restaurants, so screw the VCs.

I'll pay 15% performance for safety[1]. It's just that we have the wrong priorities, and you betrayed that default attitude again with the requirement that everything be "exactly as fast" as before. I still do not understand this focus on performance above everything else. It is absolutely unquestioned. We can't even talk about it. And it's constantly an argument that is undone by time. Machines are still getting faster. In the heydays of Moore's law, when performance was doubling literally every 12 months, if we were arguing about 15% of CPU performance, that's 2--TWO--months of performance. Now, it might be 1-2 years to get 15% single-core performance. But almost no one is limited by single-core performance anymore.

We got stuck with the worst of all possible worlds--long compile times, long debugging times, long bugtails, horrible security, rickety and hard to refactor, ugly code. Oh, but it's fast. Fast and broken. Wonderful. Wonderful. Grandma is so much happier with her 15% faster something or other that spends 95% of its time idle waiting for user input. Oh, but that 15% of 5%...man that 0.8% is keeping me up at night! We forgot to zoom out to see that people need and depend on reliable software and utterly failed at that. It's as if we removed seatbelts, airbags, windshields, and mounted knives in random places in cars because we thought everyone wanted to go fast. No other disciple in all of engineering is so wrong with their priorities. God, society should be hopping mad at us for being so hostile to them.

[1] Obviously, performance differences between "fast" languages and "safe" languages are so variable that we might as well be talking about comparing Fords to Ferraris--without specifying whether we are talking racecars (Ford makes some fast ones)! But 15% is a number we see often in the JVM world. After years in this field, I think the fastest safe language is not more than 15% off the fastest unsafe language, across the wide spectrum. Sometimes, you can get absolutely the same performance for the innermost hot loop out of a safe language vs unsafe language in some situations, you can get 2x slower. But people get terrified they'll never figure out why, that there is some kind of hidden, unknowable "language cost" they'll never get offer. Which is of course hogwash. Every program can be tuned and improved. Offer tools to find and remove bottlenecks and stop being sloppy with allocating memory.
I recall going through grad school, the only legitimate peer review according to one professor was pubmed. I tried using google scholar and she told me it was invalid, I HAD to use pubmed. The issue is pubmed is much less easy to comb through, the site itself is very basic and unintuitive, and ultimately both searches yielded the same results except that google scholar found one extra article.
Schenker is also a bit less expensive at €829 vs €859 for the Tuxedo.

while this is arguably true, it has nothing to do with the misappropriation of the original word. something can be terrible and yet not justify using words commonly agreed to mean different things. it reminds me of the recent trend to use "assault" when referring to all types of harassment, regardless of whether physical violence was carried out or even implied. you can argue that shadow banning is bad, but if you go say that it's "literally raping their identity" or something like that then you just sound like an idiot.

Not where I live. I'm seeing take-out restaurants thrive.

My family usually eats out twice a week (plus a date lunch for wifey and I), but since corona we've upped it to 3 meals a week to help the restaurants. I think others might be doing similar things.

I think there'll be a shakeout. Restaurants that serve takeout well will survive and eventually thrive, those that rely on sit-in will suffer and maybe close.

Prolonged ventilation is damaging to the lungs. But ventilation is not given lightly - usually it is for an acute deterioration and is life saving (ie without it, patient would have died in that instance).

Interestingly in COVID it appears that positioning and CPAP/BIPAP can be more effective that venting in edge cases. This is a very new phenomenon in medicine, and we probably over vented in the early course of the pandemic. We were acting in what we knew of other severe respiratory diseases, and the case data from COVID hadn’t had enough time to present best treatment modalities.

However, to suggest that the lungs are not being absolutely ravaged by the virus infecting, replicating and rupturing lung cells is ludicrous
> If you give gcc the appropriate 'march' parameter it can use vectorisation automatically if it figures out it can do it.

Yes, I'm aware of loop vectorization in C compilers. I'm also aware of loop vectorization in Java JIT compilers. Do you think there is anything specific to C or C++ that makes this easier than in Java? There isn't.

> The main argument here is that native languages let you get the most out of your CPU if you want

Most applications, including probably more than 99% of Chromium, are not the kind of code that would benefit from manually written vector intrinsics. Does the "main argument" claim that these 99% would also be 5x or 10x slower if they were written in Java?
And that strong cross draft can be blowing it directly into someone else’s airspace anyway.
Many restaurants do this already. However, its a lot of overhead to synchronize menus between a restaurant and the marketplace apps. Raising prices to make up for commissions means making prices higher on every item and choice. Then there are the customers who do not like to see different prices in different places — pre-covid this would not have gone down well. All these news articles at least raises awareness to help mitigate the customer backlash. That being said, a customer won’t want to pay a 30% up charge plus delivery and service fees. Maybe 10% which can be ok for restaurants that have more than 20% profit margin, but that’s not where many establishments are.
Maybe delivery costs would be lower if people could subscribe way out into the future... then, set it up like a paper route.

Conspiracy theories are often more about the believer than the belief.

That's not to say that some tiny fraction of conspiracy theories aren't true, and some other small percentage aren't partially true. Skepticism is a good thing. Like everything else, when it's balanced and under control.

But a sustained passion for serial conspiracy belief can become something more than just about the topics of the beliefs.

May I suggest alternative perspective on the matter?

Compared to a product like Oracle, transactions on MongoDB are very new, very niche functionality. Even MongoDB consultants do openly suggest not to use it.

MongoDB is really meant to store and retrieve documents. That's where the majority read/write concern guarantees come from.

As long as you are storing and retrieving documents you are pretty safe functionality.

Your article presents the situation as if MongoDB did not work correctly at all. That is simply not true, the most you can say is that a single (niche) feature doesn't work.

Have you ever tried distributed transactions with relational databases? Everybody knows these exist but nobody with sound mind would ever architect their application to rely on it.

Any person with a bit of experience will understand that things don't come free and some things are just too good to be true. MongoDB marketing may be a bit trigger happy with their advertisements but it does not mean the product is unusable, they just probably promised bit too much.

>At Apple's size it might be cheaper (and definitely more convenient) to operate their own hotel

Can be. Depends on the circumstances. There are the capital costs and then the company presumably outsources the running of the hotel to a hospitality company that needs to turn a profit on their management.

In general, there's been a long-term trend away from companies owning corporate retreat properties, executive meeting centers, etc. A number of big old-line tech companies I'm familiar with sold off marquee properties over the past 2 or 3 decades.

But if you're building a campus and there aren't great existing lodging options, it may make sense. They can presumably sell it off at some point if they don't want to own it.

When we keep patients ‘dry’ in ICU we aim to keep their urine output at a level that indicates safe glomerular filtration rates.

ACE2 is expressed extensively in renal tissue, so the virus is transported there in the blood, infects cells, hijacks the cellular apparatus to replicate, and then explodes to cell to continue its march of death. So I think your speculation is a bit misplaced

I should have gone into more detail, but it's because of many of the things you mentioned. Flu vaccines are not "new" .. the procedure for making them is well known and many strains are made and kept ahead of them. (I believe they're all inactivated virus, typically bread in chicken eggs). They aren't made in six months; they took decades to develop the process where strains can be isolated, inactivated and combined in a shot.

SARS1 vaccines had some very troubling imunopathic responses and feline SARS1 vaccines made reinfections worse. This will be a totally new vaccine, for a virus family we've never developed vaccines for before, and some of the techniques they're using (the DNA/RNA technique pushed by Gavi/Gates) has never had a vaccine make it through a clinical trial before.

Those are the troubling things. I wrote more about it here:
