This is the canonical introduction book recommended by Gurobi. I've found it to be great for those getting into the subject. It has math of course, but the focus is on going over the basics of LP, integer, nonlinear, Mixed-Integer...etc, followed by lots of examples. I think it's the best book to start with to get a feel for the subject of OR, before diving into the harder books.
On a non-HiDPI display (I use one that is 1680 by 1050 and one that is 1280 by 1024) fractional scaling works fine on my machine running Gnome 34 with apps that bypass XWayland and talk directly with Wayland (which is true of all the apps I use). (Google Chrome needs to be started with a couple of command-line switches to bypass XWayland.)

But your comment makes me hesitate to buy a HiDPI monitor!
DoEvents is a great tool if your project is small and you use it consciously. Just make sure it won't invoke any I/O or heavy logic. This is easy when your app is small. And DoEvents let's you KISS and short. Not a single time in my life it caused a problem because I would always switch to BackgroundWorkers as soon as the app would grow more complex.

On Error Resume Next wasn't anything really terrible either. You just enable it before a risky call so your program won't crash, do the call, disable it and validate the result of the call before using it. This way you just don't have to clutter your code with endless try-catch-finally clauses.
I mean, you don't _have_ to install another marketplace for apps.
The Russian Wikipedia entry* distinguishes between the Soyuz spacecraft and the rocket system. I don't want to assert that the Wikipedia is an authority on anything (in fact its "no original research" position deliberately avoids being one) but I suspect it's not a translation error at least. Could still be a misuse of the term; I'm certainly no expert.

> Spacecraft don't have keys for the same reason as aircraft: People will die if someone looses the key in flight.

Before steering column locks were required (steering wheel doesn't turn unless key is engaged) the automotive key really often was merely an ignition key; you could remove the and the car would continue to operate. In fact this happened to me once with my late 60s Chevy Malibu - I got out of the car in a noisy place, locked the car, and came back to discover the engine had been running the whole time.

So in that case the only risk of losing track of the key in flight is that it might hit something, not that the device would cease to operate. It would suck to be on the moon and unable to take off because someone lost the key thought!

(of course it's complicated enough to launch a rocket that a joyrider isn't really an issue).

I can't argue with that, but if you kill something, calling the result death seems more appropriate.
> In part, this is because of what sort of people make up America's elite today: not the owners of family businesses but professionals with impressive educations. Family businesses are heritable; education, by contrast, is not.

It seems that by 'rich' the article referred to professionals with high salary. I am not sure how much I will call rich someone that needs to work on a job to continue having an income. 'Prosperous', 'well off' sounds more accurate, but English is not my mother tongue.

My point is that the rich, the ultra-wealthy, can pass assets and business to their descendants and can pay their children's way into exclusive institutions.

I prefer a society were everybody have a minimum well being guaranteed and better off people just have some more luxuries.

It could be for safety but in general its more to avoid financial damage. Downtime of any kind usually result in huge financial loses and people working extra shifts. This was my main point.

>...blockchain is going to be overkill for dealing with some types of fault tolerance

But it this case likely it isn't. The current systen already works with a chain of blocks its just lacks the distributed checking and all that stuff. But "blckchains" aren't some secret sauce in this case it just an way to implement a distributed write-only database with filed proven tech. It can be as lightweight as it any other solution. The consensus part is completely irrelevant anyway because all nodes are operated by one entity. But due to the use case (money/value) of modern DLT ("blockchains") they are incredible reliable by design. The oldest DLTs that uses FBA (instead of PoW/PoS) are running since 9+ years without any error or downtime. Recreating a similar reliable system would be month and month of work followed by month of testing.

It's not about that. Forget about the Nobel Prize, the guy still has 50+(!) or so years doing pharma research, plus he discovered Ivermectin, wouldn't you want to hear what he thinks about it?

Arguments from authority are wrong, I know, but experts DO exist in any given field and you can't just dismiss what they're saying.

The shiny new geometry nodes feature in Blender is a modifier and can be used to perform some pretty nifty non-destructive trickery on basic primitives too. Not exactly like what that video shows, but still some really neat stuff can be done with it. Well worth playin' around with a bit. :)
You're likely referring to specific implementations of blockchains.

There is no requirement that the consensus mechanism used permit forking in a blockchain.
Given how Apple allows side-loading on Mac and obviously the 2 other dominant consumer platforms (Android & Windows) do as well with no significant consequences, it's pretty disingenuous for Apple to engage in these privacy/security scare tactics to maintain platform control and profits.

Add to this the fact that they only really started this campaign more than a decade after they launched the iPhone just compounds Apple's loss of credibility on this.
It sounds like we're using very similar setups for writing. :)

I've primarily been using GPT-3 (and burning through millions of tokens) so I've been experimenting with GPT-J more lately and I've found it makes significantly more basic logic errors (e.g. mixing up pronouns, "forgetting" characters, using new characters), which makes me lean more towards constantly regenerating text versus revising it, and I feel like I'm backed into a box of having to babysit ~100-200 tokens at a time instead of generating significantly more at a time like I do with GPT-3.

I also built a quick tool that lets me adjust how much context I'm using in the prompt and generate 2-3 side-by-side completions to pick and choose from (just to speed up the flow of `click best suggestion` --> `keep generating from there`), but I haven't integrated GPT-J yet since it just feels... lower quality (it feels similar to ~Babbage, IMO).

But being comparatively* free, I'm still excited about GPT-J. Do you have any tips or processes you've found to make it spit out higher-quality text? 20k tokens at a time is quite a lot -- do you also have problems with winding paths / staying on a general "plot"?

Would love to hear any suggestions you have, because I'd sure love to move off GPT-3 to something comparable in quality!
L-citrulline is a classic preworkout ingredient; also you want to get Creatine in there at some point.

Recently, I thought about a process I call "Test Coverage Driven Testing". It is similar to TDD, but more adapted to when we write tests after the code (you know you do too, at least occasionally, don't lie).

It goes roughly like this:

- write one integration test for the "happy path".

- using some test coverage report, identify untested cases.

- write unit test for those.

I find I helps me find a good balance between time invested writing tests and benefits reaped from those tests.

Do you have a similar process?

I used to sell workstations and servers years ago and trying to convince people they needed ECC Ram and that it was just insurance for (often) just the price of the extra chips on the DIMMs was a nightmare.

The amount of uninformed and inexperienced counter arguments online suggesting it was purely Intel seeking extra money (even though they didn't sell RAM) was ridiculous.

I never understood why there was so much push back from the consumer world commenting on something they had no idea about. Similar arguments for why would you ever need xxGB of RAM while also condemning the incorrect 640kb RAM Bill Gates comment.

Most people, in most places, at least acknowledge the issue. It doesn't mean they're jumping up to pay the costs, but it's an ordinary discussion about responsibility and economics rather than an assault on science.

The delusions are largely limited to one country, for whom this is not merely about the difficulty of collective action but a paranoid belief that it's a massive global hoax. That's a whole new level of delusion.

Your parent is correct. Think of a simplified example of posting a $1 charge to a customer.

POST /v1/charges `{amount: 100, currency: usd, customer: 123}`

You might do that, and then later charge them another $1:

POST /v1/charges `{amount: 100, currency: usd, customer: 123}`

The request payload would be identical, so the API can't use just that to distinguish requests. Adding an `Idempotency-Key` lets you tell the server that these are purposely two independent charges.

> this RFC requires that the server know how to distinguish two requests with different payloads but the same idempotency-key value (and return a 422 response in that case).

This is an error checking facility to make sure that the idempotency keys are being used correctly. Sending a different request with the same idempotency key is non-sensical, so the server tells its client about the problem.
If the system doesn't work but all the tests pass, then you're missing one of two things: code coverage, or articulated requirements. Either code that you're not testing is crucially responsible for the system outcome, in which case it should be tested; or the demands of a unit of code with full coverage and passing tests don't include something that a consuming unit needs it to do.

Neither of these conditions is an argument against unit testing or mocking. Both indicate a fairly basic gap in how you're testing that should be fixed directly. If integration tests would catch this gap, you're still missing the basic thing you need while incurring the cost and risks of integration tests.

Apple does not actually "take a hard stance on all apps to make sure they're not abusing privileges" though they say that they do in their advertising.
So why doesn't someone simple replace Facebook with an "internet phonebook" that allows you to easily lookup/publish links to personal blogs, email, forum accounts, IM, etc.?

Finding people you know on Facebook is only one aspect of their success and it's probably the most heavily network dependant one. The other thing that drove adoption was the relative simplicity of publishing content. Your Facebook profile was/is essentially a dumbed down webpage where you can post text, links and photos. You also get free hosting, free "email" in the form of messaging, and a bag of other features that you would normally have to set up yourself and pay for. They did a good enough job of providing all of the killer features of the internet for free to average, non-technical users.

Does anyone else take fault with the increasingly commonplace usage of the word democratize as applied to technology?

For every valid case, I see others that make my head hurt. Is it just a buzzword for telling a story with emotional appeal to users and investors?

Making something available to someone who didn’t have it earlier isn’t democratizing. And ignoring future considerations is just lazy.

If guns were invented today they’d probably touted as democratizing violence.

> Do you also agree that "A human being driving around and crossing a red light with some basic looking both ways is not a danger to anyone."?

No.

> Both can create danger to each other.

Absolute nonsense.

The person on foot is no danger to anyone. For example, two people on foot are no danger to each other. It's only when you add a car that there's any danger at all. The entire cause of any danger whatsoever is the car. Therefore it's the car's responsibility to keep things safe and to keep out of people's way.

(Of course if the car isn't given reasonable opportunity to stop then that's the pedestrian's fault - there's always a reasonableness test.)

Basically if a human being wants to cross then of course cars should stop for them, no matter if there's a crossing or not.

I can understand that; I think there's also hesitation at that point in any relationship, where both parties are unsure of how much to invest in further social interactions.

One thing I would say though: if you believe that this is an intrinsic trait that others have, rather than something that can be learned, then this belief may hold you back more than you may think.
That sort of arrangement is generally referred to as "source available" rather than "open source". The ability to fork and redistribute I think is typically considered a core aspect of open source.

And this product is presumably already source available since it consists of source code for you to integrate into your own projects.
Well, it’s always easier to just make someone else do something to attain you things in life. Not that high up on the status totem pole? Make your kid climb it. It’s just easier.

The trend actually seems to be going the other way - less deaths. See Pinker and all that.
They can do a good job, but you need to be very careful. "Oh, it's faster if you start the container once and then run all the tests in it." Yeah but now your tests are all peeing in each other's pool.

The upside of mocks is that the values returned are literally hard coded.
I think this hypothetical might miss the point of the comment it's replying to. In my mind, cheating requires intention. Now, it would be hard for the student to disprove that any of these situations were not intentional but if for example the student studied Rosetta for the exam, it's very possible the student just memorized the code and didn't reference it during the test. Is that still cheating?
This resonates with me.

I'm not at all an expert in testing; but I instinctively take the attitude that every line of test code is code that itself has to be tested, even though it's never going into production. I don't entirely trust that instinct, but I'm suspicious of test rigs and mocks. But I don't know how to test a "module" without them. Que faire.
I do not want the option to install other apps, because it gives me plausible deniability when my employer or someone is like “install this app or you’re fired”. Or if someone gets a hold of my phone and now I have a brand new app with all permissions installed.

Having the ability to side load gives the ability to people to coerce you into installing things that wouldn’t fly under a single root model.

I do not feel that computing is headed to a good place in terms of privacy and I feel like giving the Googles, Facebooks, and spyware companies more levers to pull is going in the wrong direction. (Well, maybe the right direction under normal circumstances if the tech industry was more ethical)
I had a History teacher who told me democracy often doesn't really mean anything. I've been thinking about it ever since. "Free GPT-3" would probably be better.
I mean there's two ways.

1. Just wait a few years for better hardware. Not even joking on that one. The computational requirements of most modern GAN and transformer-based approaches, like the StyleGAN image generation I was playing around with recently, would have been daunting even on the largest supercomputers just 10 or 15 years ago and before that it was science fiction.

2. Find more shortcuts. We all knew neural nets could learn any function all along, in principle. If you have infinite time and space, some of the simplest multilayer feedback networks can learn anything learnable. I don't think anyone really expected to find such relatively efficient algorithms for that, like we have in the last few years, though.

What do you mean by 'bridges change all the time too'? Some of the oldest bridges in the world were built nearly 2000 years ago. That's zero change besides basic upkeep.

What is the oldest unchanging software project you can think of? Typical software projects have a constant accrual of features. Some of the older projects like the Linux kernel are more like a mansion that keeps getting more rooms while others are demolished. Not exactly something that happens to a bridge.
I used a compiler 30 years ago for an embedded target that didn't support recursion.

There was a tradeoff. By nixing recursion the compiler could perform variable folding optimizations that would be impossible with recursion. That's because without recursion the call tree is an acyclic graph. The result is variables are held in registers and a tiny scratchpad instead of being pushed on a stack.
i think this is most compilers.

There are a total of 358k people in the US that earned $1M+ in 2020. Seems like a very small population to be talking about out of a country of 330M. There are probably only ~20k people earning $10M+.

There is a vast difference between earning mid six figures and “could be earning 7 or 8 figures”. And there is a vast difference in lifestyle between those who can maintain their lifestyle by doing nothing and those who have to grind to maintain it.

It doesn't have to be side loading though. What EU are really trying to suggest is that Apple is having too much power to dictate other business via App Store. Sideloading or Alt App Store are only some solutions.

But instead Apple uses privacy and security to flat out deny any wrong doing.

I have often thought the advice Steve gave to Tim Cook, "Dont think What he would do, do what you think is right" was all good intention but turns out to be possibly the worst advice ever.
> WalMart is very centrally planned. More than the USSR was at peak. By the 1980s, WalMart required UPC bar codes on everything, and a different bar code on cartons and cases. Headquarters in Bentonville, Arkansas did purchasing and distribution control for the entire WalMart economy. They had central planning at a level Gosplan could only dream of.

> Amazon, of course, has taken that even further.

Whenever people describe WalMart or Amazon as centrally planned economies, I can't help but scoff. The idea that "retail = economy" is wildly off base. WalMart and Amazon are generally not producing anything. They are strictly distribution! What's more, it's all set in a market economy with dynamically determined market prices. This is so far from the idea of centrally planned economies as to be a ridiculous conception, yet it's so regularly used.
