> Lenses bend EM waves proportionately to their frequency

Is this exact? I was under the impression that it's a linear approximation that's generally good enough for optical component glasses over the range of visual wavelengths.

(I always found it a bit frustrating that in my Mechanical Engineering undergraduate classes, they almost always introduced linear approximations without any discussion about the conditions under which the approximations held. Sometimes, they didn't even mention that the linearization was an approximation.)

TPCC result means nothing without context, Alibaba spent 54 million USD for hardware building the system to run the tests, in comparison 9 years before Oracle only spent 30 million.
Winning a test with almost doubled hardware cost and obviously newer and more powerful hardware, does it really matter?
Yeah definitely. I swear, those old hard drives have a way of KNOWING when you're about to back them up and failing, just to spite you.
My experience is that there are all sorts of accelerations and things that may or may not enable themselves, and no way to know these even exist without trawling through a bunch of forum threads.

An "OBS performance audit/optimizer" would be an interesting add-on. Because, yeah, it can sometimes bring an otherwise-fast machine to its knees, seemingly inexplicably.

> The phrase "planned obsolescence" implies and is a claim of intent. The obsolescence wasn't "planned" if it was simply a side-effect of value engineering... it was simply consequential. There are some proven instances of obsolescence being planned, but this is by far an exception, not the norm.

You are missing the point. I am claiming that ONE feature can be built to meet TWO objectives. One for value engineering and the other for planned obsolescence. That would make NEITHER of the two objectives a side effect.

Example: Airplanes are painted with colored paint both to prevent the metal from degrading AND to give the plane a better aesthetic. ONE feature meeting TWO objectives.

>The broad root claim above that "Consumer grade products are deliberately designed to fail." is the assertion with insufficient evidence. The video attached to that claim has a few valid examples, but a few examples over the past century is not indicative of the current state of the entire manufacturing industry... especially when there is a textbook engineering practice that does explain the same.

My broad root claim is that the practice has happened, is happening and will happen.

My evidence for this is examples of this actually occurring. And real incentives for this practice to exist.

I made no claim about how widespread the practice is. That is more your claim. Your claim is basically saying that the amount of entities practicing planned obsolescence is so minuscule that it's basically negligible.

Your evidence for your claim is that value engineering exists in a text book. That's it. You know what else exists in certain text books? How crypto works. Does that make crypto frauds and scams negligible? No.

No doubt your claim is hard to prove, the burden of proof for you is astronomically harder than it is for my point. But then think about it... why do you hold strong opinions and stances on topics that are almost impossible to prove?
Martin Odersky once mentioned that he added XML literal to Scala because it was 2000s (citation needed). Although it's hard to refrain from ridiculing these, it's probably not fair to do it. 2000s had its own collective craziness and this was one of them. We'll have such ones for 2020s but we can only spot it years later.

(Don't name it to show your smartness. Pointing a few is not hard, but pinpointing all is not possible unless you're a pure naysayer.)
I once worked for a large, urban Episcopal church. Since it was non-profit, parishioners could donate their old computers for a tax write-off. Amongst my many duties, I converted these hulks into network terminals. They ran Novell (DR) DOS on a Novell 3.12 network. I used third world cheapo compatible NICs since my annual computer budget was in the few hundreds of dollars. And as long as the patch cord wiring system held up the thing actually worked...
Check out and criticise my business idea
Been working on a business idea for about a year now and I recently bought ads. I haven't gotten any conversions yet and I wonder if it's because of my business idea or because of the ads.

Here is my idea :
My website is very simple, go on, create an account then login. On my website you can message your friends (send friend requests and create group chats), talk about games you enjoy in forums, and play free online games. For the moment it doesn't generate any revenue. But the idea is to get many users, and then try to convert into something more like Steam.

Tell me what you think of my idea! What you think of it etc... My website is thedevie.com

Most apps that close when the windows closes are not document-oriented apps. For them, there is only one window and one function. The calculator app you mention is a good example. Once you close that window the app has no other purpose it is setup to auto-close the app.

Document-oriented apps expect that, after you close the document, you might want to open another one or start a new document.

> to come up with a stable CPI number

You're imputing motive here without any evidence.

> Legitimately curious: can you think of a reasonable justification for 60% weight fluctuations of a major element of the index?

Yes. The weights are determined from survey data (Consumer Expenditure Survey, conducted by the census bureau). They aren't just made up.

As for why gasoline jumped from a weight of 2.9 in 2003 to 5.2 in 2007, probably because the price of gas doubled over that period and so it was a larger proportion of survey respondents' budgets, which results in a higher CPI weight.

> Recreation is another weight on the list that seems to fluctuate back and forth without any noticeable trend except to smooth out the numbers.

Again imputing motive without evidence.

Disposable income expenditures like recreation and photography naturally are highly responsive to economic conditions. When the economy is good people spend more on recreation. When the economy is bad they spend less on recreation. As the percentage of survey respondents' budgets that gets spent on recreation changes, so does the CPI weight. Nothing strange about that.

CPI naturally will be smoother than tracking individual items because of (1) random variations averaging out in the large basket of goods and (2) consumers adjusting purchasing behaviors in reaction to prices. There's no need to appeal to conspiracy theories about the BLS intentionally smoothing it by manipulating data.

> If the employer owns the rights, the copyright assignment is illegal and void - the employee never had the right to do it

Is that actually true though?

Suppose Alice has a full-time job with HyperSuperMegaSoft. Alice writes a patch to IndependentSoftwareFoundation's FooBolCompiler. When Alice submits the patch to IndependentSoftwareFoundation, she warrants to IndependentSoftwareFoundation that she has the right to do so. Years later, HyperSuperMegaSoft decides to sue IndependentSoftwareFoundation for including Alice's patch in their FooBolCompiler, because they claim Alice never got proper internal approval (under HyperSuperMegaSoft's internal policies and procedures) to submit the patch. Is a court going to invalidate Alice's agreement with IndependentSoftwareFoundation because Alice didn't follow the right internal procedures with her employer? Or will the court decide that IndependentSoftwareFoundation shouldn't be punished for Alice's mistake, that HyperSuperMegaSoft is bound by Alice's actions as their employee even if they didn't approve of them, that IndependentSoftwareFoundation has the right to use the software under the agreement, and that HyperSuperMegaSoft can't successfully sue IndependentSoftwareFoundation (or FooBolCompiler's end-users)–they may still be able to successfully sue Alice for violating her employment contract (although that probably is far less an attractive proposition to HyperSuperMegaSoft than suing IndependentSoftwareFoundation is.)

IANAL so I don't know what the right answer is. (The right answer probably depends on the jurisdiction.) But I get the impression some people assume that HyperSuperMegaSoft would automatically win against IndependentSoftwareFoundation, possibly without having good justification for that assumption.
And I'd argue that we have chosen such an optimal solution, where robustness is given a low weighting, and now we are experiencing a predicted downtime event. The cost of this event is spread across the whole economy, and the executives (in industry and govt) who made the decisions which led to this will experience no downside personally. Executives at rivals who have just as bad an IT problem will receive bonuses.

Essentially, we have a very weak correction incentive. Until capable hackers are endemic and ransomware hits everyone, there is little likelihood of change. Next week it could be RJR Nabisco, or Synnex/TurboTax/DuPont, or just 10,000 variants of {tiny $20m company that makes software for auditing sewerage pipe and is used by 370 of the 3000 counties in the US, and every client gets the DB corrupted}.

Hmmm. The Russians and Chinese don't go advertising their cyberwarfare exploits, but we know of them because targets will be vocal. Our targets would be vocal too.

Hmm, i think your understanding of the state of things is slightly backwards. Because Google is so large, interviews so many people, has such a strong brand name, and pays so much more than everyone else, their interview process is going to be a very well-known quantity. Therefore, the questions that they used to use all were being gamed, so they kept on adjusting and tweaking and upping the difficulty, until they ended up with where they are now.

So the point is, how do you interview if you know that everyone is going to know all the questions ahead of time? Seems like google's solution is they'll just make their questions difficult leetcode level. So, then their thinking is, sure if you're able to grind leetcode to a point that you can pass our interviews, then we'll be perfectly happy to hire you. So you've "cheated" the system by learning how to program a wide variety of difficult algorithm-heavy programs. Worst case scenario, your resume is a complete sham, but at least you're able to write the code that they're hiring you to write, and everything else that you're lacking, well, they'll be indoctrinating you in the google way anyways, so they don't care about your past experience.
Hi Mark! We had electronic and USB triggering working with SDM and CHDK before you joined. But no image transfer or control of settings by USB. We deliberately pursued mechanical triggering for places where a computer and crazy firmware wasn't an option. I donated quite a few scanners to projects and people who simply couldn't use that stuff at the digitization site.

Johannes (spreads) was one of the most inspiring people I've ever worked with, so thankful for the energy and intellect he brought to the project- and the software he built. I donated a pair of DSLRs to him as a thank-you. Last I heard he was still working in a related space, but at a higher level.

Personally, I left the project to join Apple (they refused to let me continue any work on the open- source project while I was employed there), and gave Jonathon (tenrec) control. He redesigned the scanner again and sold kits as well as produced a Raspberry Pi based controller with nice software. Seems he has closed the store.
You can't disprove those things. People who believe in ghosts or fairies or angels or gods always beliefs plus claims of evidence. You can disprove some part of the evidence, but they'll always have another bit of evidence where there's not enough data to prove anything one way or the other.

It's the same deal with space aliens visiting Earth. The evidentiary basis for that is no stronger than that for aliens. You're correct that it's preference that leads some to favor aliens over angels, etc. But that's all it is.

I wish there was a nice, easy answer on where to draw the line with surveillance. I'm actually glad that the insurrectionists left a zillion-mile wide electronic trail, but I'm all too acutely aware that these capabilities can be turned against anyone, and I'm dead-set against backdooring encryption. At least (US-specific here) there are nominally limits on what the government can do, but those limits are often ignored, and private corporations have much freer rein on what they can do with your data.
Under US law, between 1925 and 1964, it was necessary to renew copyright every 28 years.[1] There are many works which have fallen out of copyright for nonrenewal, and there are projects which are now going through copyright renewal records to determine which of these are in fact now public domain in the US. Roughly 3/4 of potentially copyrighted works (published since 1924 and initially registered) have proved to be public domain.

Once copyright has lapsed, it cannot be reinstated.

________________________________

Notes:

1. Technically, the obligation existed until the 1976 act, at which time copyright status was automatic, but was retroactively waived for works never having lapsed, back to 1964, in the 1992 act. It's complicated. (NYPL link above.)
Have a question about the safety of using environment variables to store sensitive information.

e.g. suppose you have your postgres db url in an environment variable - with the password in the string - isn't that a big no-no? If someone found an exploit in your web app container then they would also in theory get access to valuable secret info - the db data is by far most valuable part of your app imo.

Is there a more managed way to handle this kind of secret?
Slight nitpick, but all United Healthcare plans are regulated by the ACA (Obamacare). This means that they are significantly more comprehensive than the junk plans that comprised the individual market when I started freelancing.

It's unfortunate that darig's reply to your comment is being so heavily downvoted that I can't reply to it because essentially they are correct.

Most people only know how to sell their time, which is why most people are employees and many self-employed people have no free time.
It's entirely possible to be self-employed and sell something that is not your time, or maximizes the investment of your time so that you can do something once and sell it more than once.
Nah. As I mentioned, I believe alien life is very likely to exist somewhere in the universe. I'd be fucking thrilled if it were to drop by for a visit. Fairies and wizards and dragons and whatnot would be cool too. But that doesn't prevent me from seeing that all of these have been on the margins for a long time, and continue to be on the margins despite the massive increase in our ability to document things over the last couple centuries.
Are there any libraries that do string comparison for unicode characters that look alike?
> array concatenation with ~, associative and dynamic arrays as well

Yes. Walter was referring to the operator itself. Strings are arrays.

> as well as exceptions

It's not exceptions themselves, but the `new` operator. It directly allocates from the GC. That said, there is a plan to enable @nogc exceptions.

> At that point it becomes a valid question why one should learn about the pitfalls of GC free D, when one already knows that about the currently used language.

People who already know another language and are happy with it have no reason to switch. Why would they? It's people who aren't completely satisfied with a given language that are going to be more open to looking at others. And so of course then it's a matter of weighing pros and cons. Do I like the syntax? Does it feel intuitive? Am I comfortable using it? Do I find the pain points blockers or minor annoyances?

There is nothing special about D in this regard. If you aren't looking for a new language, you aren't going to try it. And if you are, you either like it or you don't.

WekaIO wrote the world's fastest filesystem in D. They did it without the GC, and went so far as to write their own GC_free standard library (which they open sourced). Their CEO talked about why in this interview:

https://dlang.org/blog/2018/12/04/interview-liran-zvibel-of-...

That said "GC-free D" is not a major selling point of the language. You will not find the maintainers recommending anyone start a D project fully GC-free unless there is a very specific use case, like that of WekaIO or the blog post author. The allocation patterns in D are different than they are in Java or C#, it's clearly defined when a collection may trigger, the @nogc attribute provides compiler enforcement for avoiding GC allocations in specific functions, a command-line switch can warn you about the same if you find @nogc too much to think about (because employing @nogc does require more consideration of your architecture), and other switches can help minimize the impact of GC.

So the tools are there for anyone who needs them. There are definitely rough edges and we are forever in need of improvement, but everything is usable and people are using D in production right now.
