Maybe JDK X+1 had gone through a deep and thorough review at some point that got it put on some "OK" list somewhere? And maybe X+2 was too new to have made it through that same deep and thorough review. It makes sense from an auditor's perspective, maybe X+2 has new bugs that X+1 didn't have. They want the good version, not the newest version.
A lot of Postscript printers are configured to print source code when there’s a syntax error in the file. My 2017 HP laser printer has this as an optional feature.
Would that not depend on what your definition of customer service is? I think the problem with airlines is that they have fallen into this myth that good customer service will lead to customers demanding more good customer service, and that’s something they can’t always guarantee. So like Starbucks and burned coffee beans, in order to standardize across the airline, many have opted for the most basic level of customer service.
> I'd rewrite this and say that the author is thinking ethically, not like scum.

The Darwinian beauty of capitalism is that a firm that sacrifices maximum business efficiency for ethics will be destroyed and replaced by ones that do not have this defect.
Patent does not protect a product, but a specific technology. If 1 technology out of 10 in a product is under patent protection the competitor (and the public) cannot copy the product as is, but is welcome to use any expired technologies any way it sees fit.

In general, it is a business decision on whether to patent a technology that it is not ready for the production: the risk of not making a product in 5 years vs the risk of competitor getting there first. It is not perfect, but I would prefer that inventions that the owner wants to own (and suppress competition for) but cannot commercialize in 5 years enter public domain. My 2c.
Can someone more familiar with the field post some applicable models for review?

Met Slim Pro Review, Legit or a Scam?
I had quite a few flights and trains booked in March and early April. They were all canceled of course.

Out of all of them, EasyJet was the only company that let me have an instant refund on their website. Most of the others made me call them (I was on the Alitalia line for 90 minutes, after hours of being flatout rejected from the call queue), some I had to issue a chargeback, and some refunded me in November. One I’m still waiting.

I also booked the Bernina Express and the only refund option is to show up at one of their stations in Switzerland I guess.

This is to say that most travel companies operate in a similar non-automated fashion because that’s what makes them the most money. EasyJet is far from the exception.
I order Domino's around once a month. The reason I order them is because they're incredibly cheap ($8 medium pies with 3 toppings, at least half the price of local pizza shops), ease of use (online purchase is seamless), tracking (you can see the stage it is in) and consistency. Pizza to me is more or less a commodity product as I'm sure it is with a lot of Americans

All of these reasons are driven by technology. The process is automated so it runs very efficiently and with minimal human intervention. No person has to constantly be opening the oven to see the progress being made, which lowers the temperature of the oven and leads to inconsistency, and takes longer. The app is nice and most importantly the product is consistent. I think once I got received a pizza with a missing topping, but didn't follow up on it.
Society. Mostly because the alternative would be something like being a hermit in the forest.
Nvidia GeForce now does the same: https://beta.play.geforcenow.com/mall/#/layout/games

For all I know, this may be in response to Stadia; I hadn’t seen this functionality when last I checked a few months back.
Maybe massive connectivity loss was the purpose. While something interesting was offline, maybe with security infrastructure disabled or weakened, likely at many places across the area, something interesting could have been done.

Hello.
As a newcomer to software-development, i am wondering what route YOU will suggest i take.
I am currently in the .NET-world and looking to expand my repertoaire and get into bioinformatics within a few years.

> I maintain it’s an odd choice given the availability of alternatives

The problem is that the "alternatives" are not reliable: image hosting sites commonly will optimise files by removing ancillary and unknown chunks, losing the data. However as long as they don't rewrite the image data itself (e.g. by resizing the PNG or putting it through a quantizer) the steganography method will ensure the data propagates correctly.
Obsidian also has a daily note extension built in to the app.
Yeah, I don't get Domino's when I want good pizza, sometimes I get the urge to eat one, even though I know I will feel terrible afterwards, and I certainly don't try anything like hot dog filled crusts.

I was surprised visiting Taiwan, the Domino's there is actually pretty passable.
A naive implementation wouldn't work though - some companies need to sue lots of people, but will win almost all the time. It seems wrong to penalise the defendant because they committed a tort against someone who regularly successfully sues others.

Mind you, there's a "build footpaths where people walk" aspect here too. If someone is suing lots of people it might be that the law is 'wrong' (contrary to modal picnic views of morality, say) and that the demos don't find the action to be something the law should prohibit?
Do you have a source for that fishy number?
> It is nothing new, nor is it catastrophic.

Predator-prey cycles are of course neither new nor catastrophic, but the planetary extinction event we're in the midst of is definitely a catastrophe.

Maybe not yet to the same degree as the oxygenation of the atmosphere, but we're only just getting started.
The point is that just because you don't get paid for doing it, it doesn't mean that an activity has no value.

Your entire way of thinking about economics is wrong.
> Does statistical causal analysis work when there are this many variables?

Yes, that's the whole point. It works when you can "simulate" experiments by looking at a large number of events.

E.g. DNA evolution in genetics, drug testing in medicine, studying failure modes in aeronautics...
> What you would really want to do is compare the operational requirements for EVs and the general usage of motor vehicles to see what proportion of the general usage of motor vehicles can be replaced by EVs and their operational requirements.

Okay, has this been done by anyone? Something that shows current limitations of the infrastructure and projected mitigation of those?

Relevant for what? The question isn't really complete.

Is PHP still a language in use, should I support it if I build tools or platforms for programmers? Sure. It's in use in many places.

Is PHP still a language worth learning if I intend to do agency style web development? Probably yeah. It still has a high showing in that domain.

Is PHP relevant for someone writing brand new distributed systems? Probably not. It has poor ergonomics and a bad concurrency story, and there are better languages for any criteria you care about.

Is PHP relevant outside of backend web services? No, and it never has been.

Is PHP relevant for PL research? Absolutely not. PHP's language design is almost wholly parasitic. It has few ideas of its own.

But... that's not really what we're writing about, when we're writing about relevance. Relevance here is a value judgement. But it's not PHP's quality as a language that makes it so ubiquitous. PHP is largely widespread because for a long time it had by far and away the best deployment story. You could get a LAMP server provisioned and be up within minutes.

I think the really interesting question is, "based on what made PHP so ubiquitous, what's the next PHP?". And I think the answer is JavaScript.

JS is quickly becoming the platform of least resistance. I can write a script and have it served on AWS Lambda within seconds. I can go into my function code and add logging on the fly. I have the same fast feedback cycle, in other words, that I would have had with PHP fifteen years ago.

I'm becoming more and more convinced that the most powerful tool a language can provide is a REPL. The faster I can turn abstract ideas concrete, the better. And the next generation of programming languages will live or die on their "playability".
I disagree. Southwest engages in a lot of white washing and PR to project this image of an airline that “cares” but in actuality they’re no better than any others. On airlines it’s not YMMV it’s “dignity comes with a price.”
Agreed!

> Computer Programming is not Math. Let me say it again, computer programming is not Math and will never be. You want to learn computer programming, then learn computer programming.

Programming is far more aligned with writing than math. If you want to be a better programmer be a better writer. Math will not make you a better programmer.

Conversely, programming will not make you a better writer, but it will make you better at math. This is complicated, but provable with testing.

The term math is extremely misunderstood. Math is not a practical exercise, it is a philosophy, a way of thinking. Lay people believe the word math is interchangeable with arithmetic, which it isn't. Arithmetic is the expression of immediate computation. Math is more than that.

Writing algorithms and instructions is algebra. Algorithms are always algebra. Always. Algebra is the conveyance of instructions, which is inclusive of arithmetic, but is more expansive and accounts for variability. The word algorithm literally comes from the Latinized name for the father of Algebra, Algorithmi. https://en.wikipedia.org/wiki/Muhammad_ibn_Musa_al-Khwarizmi

Planning is calculus. Calculus is the expression of continuous change. Calculus accounts for states in fluctuation and differentiation. Calculus allows for thinking in terms of various potentials and collections of decisions.

The reason why writing makes you a stronger programmer but math doesn't is because math doesn't force critical examination like writing does, at least not until you get to Calculus. The reason programming does make you better at math is because it teaches you to solve tough math problems without ever having to do math, because Math is a philosophy, a way of thinking.

This is provable with numbers. Simply test people, compare the testers, and then compare those differences against programming capability. This is provable objectively with numbers. If you want to hire better programmers test for writing performance. The best filter of a group of candidates, for programming potential, is a tough essay to write under time pressure.

When I took the military aptitude test, the ASVAB, the first time I was 17. My scores indicated that I was smarter than 79% of the people who took the test that year, but the only score that really mattered is the GT score. It is an examination of solving complex mathematical word problems under time pressure and is graded on a scale of 0-130. I scored I 107. Smarter than average but not smart enough to become a military officer. 17 years later when I wanted to be a military officer I needed to retake that test at which point I was smarter than 98% of the population who took the test that year and I scored a GT score of 129 (out of 130). I had been programming for 6 years at that point.
Why is that beautiful? I see ugly.
Rendering is different because the assets are very interdependent and the tooling is very POSIX specific. Rendering a scene (especially with ray tracing) can use thousands of assets from the movie even if they aren't directly on screen. Artists draw and save files in tools like Autodesk Maya and renderers read files from disk and work on them while in memory.

For some assets and tooling FUSE mounted s3 can work but generally FUSE and other userspace mounters I've seen slow down artists and rendering measurably.

Think of rendering assets more like code files and git with trunk based development. You want all of your artists to use the latest assets which are daily being updated. All of the assets should be co-located and you don't want geo-replication because of latency. Even if your artists are located all over the world you'll want them to store the saved assets in one place. Where the rendering happens.

There will be different assets that are hot as the movie progresses. But you're more likely to try to keep the latest version of all assets hot rather than all versions of specific assets hot.

Most studios use HPC style environments. NFS + big compute servers connected with high bandwidth.
You are making a lot of ontological and epistemological assumptions that are contentious in the philosophy of math. Not saying you are wrong in thinking this, metaphysical questions don't necessarily have answers, but many would not agree with you.
I was baffled by this:
"The worst part is that serving the same files from disks local to the VMs is 44x faster than from persistent volumes (267MB/s vs 6MB/s)."

Is it a configuration issue on their side or do the LKE volumes are really limited to 6MB/s on linode?

How can you be happy with this for production??
Which aspects of bcrypt are you referring to by "things like bcrypt"?
Has this ever actually happened?
It seems like this article has a different definition for "Wootz Steel" than Devereaux, though. Here, it specifically refers to the banded patterning on the blades, and it's talking about the metallurgy that produces them. Apparently it's not only the crucible process that's required, but a specific range of alloys that produce the required separation when melted. And that actually did disappear, no one was making these for quite some time, and (apparently) routine crucible steel (which still works very well for weapons) from other ores doesn't show the same pattern.
>>To produce Hidrogen, you need electric energy, or some very hot source that could be turn to electricity at a high efficiency.

This is not a true statement... Aluminum alloys readily liberate H2 from H20 at room temperarure (an exothermic reaction generating roughly equal parts thermal and chemical potential energy - both of which of course can be used for work) [1].

The oxidized aluminum is environmentally benign and can be recycled by applying more energy to deoxydize the product. The 'purification' process is ultimately where the useful energy comes from. The energy to power the purification can come from any number of sources - but as good stewards, we opt for clean energy sources. Al smelting historically produced a lot of carbon, but thanks to R&D by Apple, there are new carbon-free alternatives for this process [2].

At my company we are researching application of this energy infrastructure loop for powering ships (where source water is abundant). Essentalially, the Al+ is your fuel (battery), and from a volumetric energy density perspective (important for ships), you can store about 2X as much as gasoline/diesel - and way better than liquified or compressed H2 storage. However, on a mass energy density perspective (important for automobiles), it is a bit worse (heavier) than hydrocarbon fuels. Again though, each application has it's own constraints when considering an energy storage medium.

The automotive or civil sectors aren't the only use-cases for hydrogen fuel cells. One needs to take a look at all sectors to really grasp the global impact. A large part of my job is to explore this big-picutre aspect, because we need to understand the long term infrastructure stability/availability of potential "clean" energy supply chains, and it's VERY complex when you consider process efficiencies over the entire supply chain, raw material abundance and regeneration potential/economics/environmental impacts/speed, geopolitical forces affecting supply chains, the list goes on and on (and on).

H2 is an interesting "energy storage" option and it will certainly continue to be researched and applied broadly.

If stadia exists in 5 years time (which I think it will, but still).

That and I really can't picture it ever being fast enough to keep up with a real machine on anything other than pretty games rather than (say) counterstrike.
The commenter has a good heart. Plenty of encouraging sentences. However, the overall comment does come across as an underhanded criticism.
* Someone had access to a delivery system that could be used to attack thousands of people's machines by rolling out a rogue release.
* This someone was forced to install a specific antivirus due to compliance with an industry certification.

This antivirus called home, and was from an obscure vendor. This someone wasn't able to change any of this, and also didn't have power to choose another vendor.

If you followed the rules by the book, you couldn't even introduce a third machine to authenticate things without this silly protection. So, what should did they do?

Installed the antivirus on a virtual machine with no access to the host computer, and program it to be fired up for a couple of minutes a day, just to keep the stupid antivirus happy by calling home.
USA, like UK, has a small claims system too. In theory that makes legal redress less costly (for the complainant and the court system).

It's worse than that, at one point printer drivers were run in the kernel. I remember a customer site where just opening a queue blue screened the server.
a software engineering degree that takes 4 years is a waste of time then

those trades schools that popped up are good enough
I think it's misguided to be considering this issue as "customer service". This is about following the law/regulation.

Customer service can indeed be variable, and it's up to the company to pick their approach (terrible/no CS and low prices or very good CS and higher prices).

When it comes to complying with the law/regulation, if your company is bound by those laws then it should comply just like every other company does. "Following the law" shouldn't depend on how much you pay; the companies expect the customer to follow the law, so the reverse should apply too.

The problem seems to be that the current law/regulation isn't up to scratch and allows companies to act in bad faith and get away with it (the author is indeed correct that all of this can be made easier through automation and the airline not doing so should be considered obvious evidence of bad faith).
Instant.io is WebTorrent, where everything is handled client side using JavaScript.

Webtor is server side, downloading using Bittorrent protocol on their server. This is stupid and will put them in a lot of trouble.
This isn't some gotcha; Apple's policy has always been that if you found the App Store policies too restrictive you should make a web app.
If you give people one choice, you have 2 different user cases to deal with. If you give people choice over two two separate, you have now 4 different casess...

Companies like Apple limit the choices so that they can provide single user experience. Users are bulk mass for them, not individuals.

If you use Apple products, you are paying for not to have a choice.
Cancellation Policy as a Competitive Advantage?
Me and my wife run a last minute tour and activity marketplace called Bubba Booking that allows in-destination consumers to find things to do either today, tomorrow or this week. Our tours are listed based on the user's exact location and party size. We started the company after going on our honeymoon and discovering that finding tours nearby the day of is almost impossible.

2 years later and we have 15K live tours and activities...and we finally made our first real sale this week!

We are now trying to determine how to use cancellation policies to differentiate us from our competitors.

For context, we are contractually obligated to adopt each tour partner's cancellation policy (some have 24 hours, some have 48 hours, some have 7 days, some have no refunds at all). Here are our options to choose from: (keep in mind that we only book up to seven days out)

1. Follow each partner's policy: No competitive advantage and operationally difficult to track
2. No cancellations...period: Less consumer friendly, but since we are already last minute in nature, we think that most people are committed to going at the time of booking anyway; plus, it's easy to operationalize with a small staff
3. Free Cancellations...always: Makes us extremely consumer friendly. But we would be on the hook to pay 100% of any missed revenue. So if we make 10% commission on each tour, we'd need 9 successful bookings of the same amount to break even on the 1 missed tour. This could sink us pretty quick if the people cancelling for frivolous reasons outweighed the incremental bookings we'd get from a lax policy

In the absence of enough real data, what do you guys think?
So, you don't see how EV could take over from gasoline? Because you're describing the exact same "the infra's not there, and the tech's not good enough" situation as before.

If hydrogen extraction can be be made efficient enough to economically make more sense than batteries, that's the only necessary criterium. If it can, the rest is a matter of time. If even with this approach it can't, then it won't happen. It's really just economics.
Maybe in the 1800's.

Today cutting edge astronomy isn't that removed from telescope design. Understanding how the instrument works and it's limitations is pretty much essential to understand the data it produces.
You must live next to an anomalous domino's location. My household orders 2x weekly, same order every time. Quality and delivery time varies wildly between orders, and the "tracker" is clearly an estimate rather than a true tracker. This has been true for years across several moves in several states around the country.

Edit: Adding link to story where guy verifies tracker is not real - https://melmagazine.com/en-us/story/i-staked-out-my-local-do...
Is it using anything more than WebRTC? (Or HLS if the low latency mode is finally in?)

Is there a reason not to switch e.g. YouTube and Netflix, Zoom etc to a similar model and forego the app? (Yes, the app has its positives but also the 15%-30% tax)
There are rumors that Intel is about to replace its current CEO, Bob Swan.

If so, I'll be curious to see if that affects Intel's technical competitiveness.
This may be a tangential, but I've recently found that it really is useful to track all/most of these pieces of personal data. I spent a long time trying to figure out the best way to go about this before ultimately just settling on plaintext files and Git. Some of my data goes into CSV files that I generally just manually edit with Vim, some (ie. notes) just goes into literal text files. Sensitive data lives in a separate repo and is encrypted using GNU pass

Since this is how I'm used to keeping track of code and configurations, the friction has been surprisingly low; I'd even go so far as to say I find it fun. I'm sure my specific setup is not what's right for everyone but it feels right for me and I think that's the whole point.
