> The reason for Chrome's massive memory requirements is that they make memory vs. CPU/performance/security tradeoffs on a regular basis

Do they actually test both approaches, or is it more a matter of "we can code it way A or way B, and way A uses more memory, but we think it'll be faster"?

Many years ago I worked at Watcom, back when they made "the" C++ compiler for DOS games. (Doom, Descent, Duke Nukem 3D, and Tomb Raider all used it.)

The compiler had various optimization settings, and some optimized for size, while other optimized for speed. The compiler was used to compile itself. They normally compiled with the "optimize for size" settings enabled, but one time they decided to try optimizing it for speed to see how fast it could be.

It turned out that optimizing it "for speed" made it considerably slower because of the cache.
Broadly, yes. Mechanics almost certainly. Enthusiasts can get away with not knowing some things to a point, but I think you either lose the enthusiasm or pick it up eventually.
"All bets are off" is an insane way to characterize this. IF a project is 99.99% safe code and has one unsafe dependency that is a massive difference from a project that is 100% unsafe. The surface area of the project that may be vulnerable is going to be relatively tiny.

As for an echo chamber, yeah the Rust community downvotes way too much. I find myself upvoting just to counter it.

But the downvoted comments here are legitimately bad. Someone being pedantic about the 70%, and being wrong, and another person calling this propaganda.

They charged him $82,000 to use a ventilator. I wonder if that includes supplies and labor, because you can buy multiple ventilators for that price, and they’re reusable.

Also, $400,000 to seal a hospital room seems excessive. I don’t imagine how it could possibly cost that much. Add a few hepa filters to pull negative pressure, and you’re already pretty close (not counting decontaminating the doctors on the way in and out, but still, $400K?)
People have rethought computers from the ground up. The C++ version was slightly faster in a benchmark, though, so their thought was ignored.
I am really happy to be a student of UoPeople which is one of the world highly rated tuision free online University. The school has helped me to overcome my problem of time management and communication at work place has improved. However, I am glad that it has given me an opportunity of having my degree certificate in the future. Being a student at UoPeople requires internal motivation and patience because the workload is much.
Professional bike fitting is sort of a sub-discipline of physical therapy, at least in the US. (That might not be obvious to people who haven't had a professional bike fit; it wasn't to me before I did.) To the extent your health insurance covers PT, it covers PT bike fits.

I would expect that to be an outlier in the sulfur/sulfuric compounds concentration low to ground, but wouldn't expect it to show up in the NOx concentration satellites pick up (averaged over a fortnight and the whole of the troposphere). And indeed, if I compare the maps of Germany for the timeframe 23-12-2019 - 06-01-2020 with the one of 16-12-2019 - 30-12-2019, then I fail to see any reminiscence of the Sylvester Nacht.
Oh yeah? How else would you define the context of people who gather regularly in community in relation to spirituality or gatherings for ceremony? Curious what preconceptions and prejudices you have of who you classify that are automatically discredited in your mind because they use the term "spiritual circle" - or am I misunderstanding what in that sentence discredits me?

Ever been to an Ayahuasca ceremony or talking circle? Just trying to get an idea of your own experiences.
> The reason for Chrome's massive memory requirements is that they make memory vs. CPU/performance/security tradeoffs on a regular basis, and usually make them against memory.

This is generally a good trade. Memory is not very useful (modulo filesystem caches) when you're not using it, and has a very low cost when you are (extremely tiny power consumption). CPU cycles cost power (leading to heat dissipation and battery life loss) when you use any amount, and latency when you use too much. Latency directly affects user experience and efficiency, which is a much higher cost than "my RAM is at 75% usage".

Additionally, Chrome's tradeoff is such that it works out better on cheaper devices. Memory is far cheaper than more powerful processors - which also reduce battery life, which is even more expensive. On more expensive devices, you have all the memory you need for Chrome anyway, so you're just getting better latency.

Finally, there are very few cases where you should have a large number of Chrome tabs open anyway. Multi-tasking is impossible (the human brain simply doesn't support it) and rapid context-switches are inefficient. As much fun as it might be to have 5 tabs open on each of 10 different topics, you're simply decreasing your productivity and capacity for focus. Even when doing multi-disciplinary research, there are a ton of ways to get around the problem of running out of memory due to Chrome tabs: printing pages to PDF, turning off JavaScript, downloading research papers and reading them in a native PDF viewer, extracting content from webpages and inserting into local documents, and the classic using darn bookmarks instead of tabs like they were intended to be used.

(of course, in an ideal world, all web browsers would use absolutely no memory or processing power whatsoever - I'm just defending this particular engineering tradeoff)
CDN for your app sounds like a minority use case, a service that could be sold separately. Not even relevant for native-only apps. I don't want Apple to try to justify the 30% with luxury services, I just want them to reduce the cut.

I am a proud MBA student of UOP. As I am currently living in the US, transferability of courses credits doesn't apply to me. I am enjoying the Tuition free and have already made arrangement with a Public University in Florida for a PhD in Public Administration.

One of my short-term goals is to help the community where I am living now and my home country with this degree.

Uopeople might not be accepted yet in other regions but I heard that they are working on it. When you want to help, you can get the most out of "a little". Uopeple degree helps you make that happen!

This makes sense to me. Facebook knows that consumers are finicky when it comes to social networks and they need to stay on top of the latest fads. Once new social networks catch fire Facebook needs to do anything possible to gain control of them, and venture investing is one way to do that.
Proven asm code like in TAOCP is safer than any other language. For example you know exactly what the FPU will do. Good luck with any compiler.

I know that is not what people mean with "unsafe", but it is getting tiresome.

That translates to "don't use SQLite", right?

How would an application that uses SQLite as a file format be able to scan for malicious database files that trigger buffer overflows in the SQLite engine? I'm really not sure what you're suggesting.
For anyone interested in tracking their own bike fit at home, I've been building a web app based on the park tools road positioning chart (https://www.parktool.com/blog/repair-help/road-positioning-c...).

This is different than frame geometry, which is what is being discussed in this 99spokes article, but it's quite useful for anyone that likes to play with their fit or wants to transfer their current fit to a new frame.

It's a work in progress, but the app can be found here: http://app.mybike.fit.
It’s basically a pull request. There are going to be mistakes and changes. You can pull it and run it yourself if you’d like, but don’t say it’s shipped until it lands on master.

There was some consideration for a formal library based rust GC back in 2018 such that one could write GC<CyclicDataType> and get the benefits of a GC such as

- Not leaking memory
- Not invoking unsafe
- Not angering the rust compiler

None of those efforts stabilized to my knowledge, and the libraries developed for this task all have experimental/research tags associated to them.

For better or worse all the guides for using rust strongly encourage avoidance of primitive cyclic structures such as doubly linked lists, graphs, and other structures in favor of statically allocated fixed size variants. Like golang's preference for map/list as the only primitive structures, this is a constraint that one can get used to for most problems. But it doesn't feel great that as a language there are basic algorithms and datastructures that can't be idiomatically coded in the language.

I'm surprised to see your comment is voted up to the top place. The moment I read your comment, I could imagine what people would say with outrage: tone deaf; you just don't care; you're a racist so you don't see the racism in such oppressive language; if someone feels offended, then the language is offensive so we must take it out; if you're not with us, the you're against us, etc and etc.

I personally always wonder where the boundary is for such demand of total conformity. Anyone who's familiar with The French Revolution and The Chinese Cultural Revolution will be cautious, to say the least, because it is so easy to see how much evil was done in the name of righteousness. That said, I find it hard to argue about the framework of this second-international-like movement. After all, you're tone-deaf if you deny that a phrase may be offensive to even one person, right? Moral high ground, well, is a high ground.

The map is actually about necessarily true properties that the territory is built on. That in any experience the features of the map exists in the territory.

The author argues instead not to be confused with the map because of potential deviation from the reality of the territory. But the map is about the categorical truths of reality which the territory is conforming to.

It’s what guarantees mathematics’ “unreasonable effectiveness”. Mathematical or scientific maps are discussing necessary properties of all human experience—-a type of knowledge called the a priori synthetic.

And here we get at the root of the problem with the North American diet... The fact that people think an ingredient list like this is acceptable or 'not that bad' is a problem.

The 'white bread' ingredient list looks nothing like real bread. Sugar? Oil? These are ingredients in muffins and cakes, not bread. The wheat they use has been processed to the point that a few key vitamins have to be added back just to make it legal again.

The ketchup and pickles are basically jam and sliced candy, there's so much sugar in them.

Not to mention the salt levels in everything.

If you eat low quality white bread and cheap condiments with every meal, you might as well have a candy bar and a bag of chips instead. But we've normalized it, we think we're eating home cooked food each time we reach for a plastic bottle or bag.

I also want to point out that "100% Pure USDA inspected beef with no fillers or extenders" doesn't mean what it sounds like. What this doesn't list are all the things that are allowed to be in your cheap, factory farmed beef and still be called 100% pure beef, like ammonia-treated lean highly textured beef (LFTB or 'pink slime': https://en.wikipedia.org/wiki/Pink_slime), HGH, antibiotics, etc.

By all means go out and enjoy some junk once in a while, but we've gotta stop normalizing ultra-processed foods in our homes.
You're assuming also that peer review will fix statistics issues. Statistics will often fall through the cracks.
>I think it is also very hard to make a performance argument in 2020.

I think it is very EASY to make a performance argument in 2020. In every domain, from my phone, to my desktop pc, to our huge AWS servers at work, I encounter software that is slow. We struggle with our C/C+ database at work running on top of a C/C++ operating system. We can't buy a bigger server and it isn't fast enough to handle the load we get recently recently due to covid. You think I should be happy to incur GC overhead in both the OS and Database? No way! That would cost us a lot of money, and require a more complex architecture. (which also costs money)

On my desktop and phone I encounter applications that are annoyingly slow to start up, to compile, all kinds of things. The last thing I want is JVM or .NET runtime overhead occuring even at the level of my operating system, device drivers, etc adding to that. CPU cache space is precious, the low level things that everything else runs upon should be as efficient as possible.
I feel like I just watched the original first presentation of SQL injection - this is that big a deal. (I can't find the link, but the guy who gave that presentation thought it bombed because people started getting up and walking out five minutes into his talk - it turned out they were trying to get to the pay phones first so they could call back to their offices and alert them that the world had just been lit on fire).
I'm not convinced.

If lockpicking and other ancient hobbies are anything to go on, it doesn't matter how many redesigns you go through; people will just create new specialized/innovative tools to break/attack the most popular ones.
A few useful phrases to memorize:

When someone asks for information, rather than try to answer immediately, or rush to research, ask, "When do you need that by?" Even if they tell you it's urgent, it causes them to consider.

"Sure, I'd be glad to. Just let my boss know you need me." If they hem and haw, be suspicious.

"What budget is that coming out of?"

Other useful tidbits: Politics is a euphemism for, someone's ego will otherwise get hurt. Tangentially, your ego isn't you. Don't let it getting hurt affect your thinking.

Most people are naturally good; the one's who aren't work hard to position themselves in a position handling communications. So be careful to route communications as directly as allowed, and regularly check what's incoming.

Faith is blind, trust is earned.

Indeed.

But my first thought is: how many programs am I using right now on my laptop, that don't have such test coverage? and... how much (probably) undiscovered holes will they have?

That without count, that we're living in the times of the hardware related bugs.
Due to its strong and simple C bindings, there's no reason new kernel modules can't default to being written in Rust, and allow Rust to spread from the "outside in" to the heart of the kernel. I don't advocate wide-scale rewriting of the kernel, but I do think default-to-rust for new kernel components and modules is rational and improves the system.
Is Rust a good choice for applications programming? Does it support GUI (dialogs, etc).

This particular software is for water utilities to model and simulate their water and waste water networks.

It's mostly used so utilites can forecast growth in their areas for the next 25+ years and see the impact on their networks and feed into their capital work projects.

A decently sized utility may spend up to $200M/yr on capital works so $40k isn't even a line item!

There is completion in the market but consultants are forced to use what their clients pick and most utilites aren't that price sensitive.

There are also open source alternatives by the EPA[1][2], and most commercial operators are just wrappers around this public domain software.

I'm trying to create FOSS to help view and run these models.

Others have mentioned that "insider trading" isn't the right terminology here. But more generally, I honestly don't think this is an issue from antitrust perspective. Imagine that instead Facebook granted exclusive access to all of that data to an external VC firm for a fee. IANAL but my impression is that relationship would be perfectly legal - just like similar arrangements between, e.g., hedge funds and satellite data companies.

Now, compare that to a retail store working with the store across the street to fix prices - very illegal, unless the same company owns both stores, in which case it's just called "price discrimination" or "good business". That type of instance - where the behavior would be illegal if it were coordinated between competing firms - is where antitrust concerns really come into play.

Of course, it gets murkier (and becomes a very obvious anti-trust issue) when it comes to acquisitions of competing firms like Instagram. I wouldn't be surprised at all if Facebook's goal here is to acquire stakes in potential competitors while they're still small enough to fly under antitrust authorities' radar.
