To generate electricity you need a hot side and a cool side.

The huge towers on power plants are for cooling the warm (waste) output. If you can get someone to cool your warm waste water even further than the cooling towers would, it would both increase efficiency of electricity generation, and use the boatloads of low grade heat for something useful.

You still need independent cooling capability either way.
This is quite significant given market is very bullish on Amazon (Goldman is just all over it). The expectations are set sky high to do well during these times. But if you look at things as consumer, it doesn't look so good. Personally, I've significantly less orders on Amazon these days because of huge delivery times. Sure, orders for "essentials" might have gone up but can that offset the gap? Also, sellers are very dissopointed with their items not getting delivered and many have started to look for alternate channels.

Given all these, I wonder how things will pan out. Wall street expectations for Amazon to do well this quarter is sky high but behind the curtain things might have taken significant hit.
> Part of me wishes it is for battery life, yet sadly in many area's like this when we gain battery life we find that offset with a smaller battery and the marketing of how it is now lighter prevails.

The iPhone has gotten thicker and heavier year-over-year for every year since the iPhone 6, mainly due to monotonically-increasing battery capacity, and the new MacBook Pros are also thicker, heavier and with a bigger battery than the outgoing ones too. I'm not sure where this "they always make it thinner and cut battery capacity!" meme comes from.
This is interesting timing given the general decline of ad revenue due to the COVID economic slowdown. I'm surprised and impressed that they are making things harder for advertisers when then are probably fighting harder for every ad dollar.
Yes I did read it all, like I said the title is a quite click baity. As far sharing data with people(or other lifeforms) 10k years from now,that is an entirely different problem than "How to store data forever".

I'm not saying I have the answer to your title or the other problem, both good questions that I wish I did have answers to. I believe that the voyager team created a golden record as they faced a simmilar communication/interpretation issue.

Another "out there" idea that might solve the problem would be attaching a transmitter to a comet with a regular and frequent orbit, possibly Halley's comet which returns every 75 years, it is a short enough duration that the technology should still be available to receive the data. The comet idea would work well in preventing future generations from corrupting the data. Eg history is written by the victors of war.

Other than those ideas, short of creating a religion I cant see too many ways to store data forever and keep it useful and uncorrupted. Which is kind of too bad and "too good to be true too!" as per my original comment! ;)
Nothing to add to this except to say that Generatingfunctionology is an awesome book. Although I haven't read it, another in the same space is A=B, also co-authored by Wilf (https://www.math.upenn.edu/~wilf/AeqB.html) (another co-author is Zeilberger, whose name anyone interested in computational discrete math will recognise).
I actually tried installing xubuntu-desktop first (and then plain old xfce) as I fancied switching back to them after a few years using Gnome. But you're definitely right that out-of-the-box, XFCE HiDPI support was lacking. Widgets (panels, icons, etc) and fonts all scaled fairly independently, and I gave us after manually resizing a few elements.

On Ubuntu 20.04 (with Gnome), it just worked (with the exception of Chromium/CEF/Blink based applications like Chrome and Teams, which needed the aforementioned command line argument to scale them). I actually had to undo most of the scaling changes that came across with my restored home folder. The one other thing I had to change was the Terminal font as the default was a little too small to use comfortably on my laptop screen - I opted for Liberation Mono Regular, 12pt (px?) with 1.10x height.

As a former long-time XFCE proponent, I recommend you give Ubuntu + Gnome a try. It's the best it's been since the Gnome 2 days, and is no-where near as power hungry as it has been in recent years. The most power-hungry application I'm running is Evolution, where the webkit process that renders HTML email frequently gets out of control and burns 40% CPU until I restart it (I'd use Thunderbird but the Lightning plugin https://github.com/ExchangeCalendar/exchangecalendar to handle Exchange calendar stopped working with recent versions of Thunderbird some months ago).

Honest question: what are you talking about?
I don't think even flagship phones have "quality chip" inside. Phone OS's are still running without swap memory support to cope with poor quality of their onboard eMMC (which leads to OOM-killing "background" apps instead of just swapping memory out.)

Sure, but this puts the spotlight back on the countries which allow shady crap.

Take the United Kingdom. Google says Foo Ltd. are the advertiser, who are Foo Ltd? Well the UK legally requires Foo Ltd. to register with Companies House, a government agency, and this registration legally must identify Persons with Significant Control, actual humans who make decisions for Foo Ltd.

But when you look closer you discover that Foo Ltd has a company secretary who lives in a run down area of an ex-industrial city, and who is listed as secretary for 1800 other companies, and its offices are registered as that person's flat. The PSC section is filled out with the name Offshore Holdings Inc. offering the address of a law firm in the British Virgin Islands, even though the law is clear that Persons means very specifically human individuals.

The UK could clean this up, but of course the people hidden behind this sort of thing are actually wealthy and powerful and are doing all they can to ensure nothing changes. Similar things happen in the US, and in several other developed nations you probably think of as law-abiding and straight dealing. Google can't fix any of that, so this is all you get.

It's very rare for people to rise up against their leaders when they have food.

Since food is so very cheap in todays world, a country has to be in a very dire economic position before the government can't provide the people food and they overthrow it.

Even so, most governments will happily use their army against their own people, and with modern weapons being so efficient, even failing to feed your people doesn't necessarily lead to a change in government. Modern governments are very stable, except for outside influence.

> How can the kernel trust your offline verification?

My thinking was that I would trust the offline verification, and this would be enough for me (as superuser) to load the precompiled module into the kernel. I believe LLVM does something vaguely comparable, where it can verify that bitcode modules are well-formed, to protect against certain classes of compiler bugs. (Java of course does its class-verification at runtime.)

I don't think this idea is all that different though. If the JIT implements caching of its generated native-code (assuming it can do this securely) then we'd get the best of both worlds: I don't need to be a superuser, and we avoid needless recompilation.

> How do you write programs which decide, at run time, to move compute closer to the hardware?

When would this make sense? If you've got a working kernel implementation, which is robust and trusted, why would you not use it?
I wonder what effect it will have on future of the countries.

As majority of the people who are dying have cormobities or they are old that means now government will not have to spend money on pension or healthcare and this will lessen the tax burden!?

What? It's anything but the syntax. The automatical live updates and the latency, the diff algorithm and the size of the payload, no client/api/controllers/routes needed, the scalability and stability, and the free clustering behind the framework.

Can you rebuild this demo in Go or Scala in 15 mins or in 1 hour, correctly push any updates to the client while maintaining the robustness and sharding across the cluster? Writing stateful services correctly is very hard using an average web framework.

I need at least 1 day to implement the same in Go or Scala, only the functionality but neither the clustering nor the optimization. And I'm considering I myself a functional programmer that is very familiar with Scala.
This is sort of a "no one goes there anymore, it's too crowded" criticism. Huge delivery times are because they're getting so many orders (which means so much revenue, which means so much profit).
Is the question on the table whether, all other things being equal, this change would decrease carbon output per unit work completed, or is the question whether Google is greener after this change?

For the latter question, we have insufficient data. Google's datacenter infrastructure is huge and complicated, and if one factors in all the interdependencies and purchased carbon offsets, one needs way more data than this announcement blurb gives out to answer that question. Maybe they have an additional process to determine whether their most carbon-negative datacenters can be switched off during peak coal-use and this work unblocked them from enabling that feature? We don't know.

For the former question, yes.
For me static typing is essential not when I am writing a new application from scratch, but when I am coming into huge old legacy code projects. For example, I am currently working on a messy and old Swift / Objective C application and having first class IDE support for things like calling hierarchies is pretty amazing to unwind spaghetti code. Also, it's a good feeling to be able to delete a big chunk of code and be 100% confident that its not being used anywhere if your project compiles. Does Dialyzer seem like it would allow you to do things like this safely as well?

My other huge gripe about Elixir when I worked on it last year was lack of IDE autocompletion. This to me is a the #1 dealbreaker in working with dynamically typed languages. Im a horrible speller and having to run my program every time just to find out that I missed a capital letter somewhere in my code is infuriating.

Has Dialyzer and IDEs (VSCode I assume) gotten good enough yet to have decent autocomplete support? When I was using Elixir with WebStorm the experience was less than optimal.
If your customers hate MVP’s then you got the V wrong. The whole point is it’s the minimal things that’s Viable and how much that is depends on the product and market. For some products, the minimal thing that’s viable really is minimal, for others it’s rather complete. IMHO the point of MVP’s is to do the least work necessary to make the customer happy with the product (ie not was to big time on unnecessary or nice to have things that can come later), not to build a minimal thing.
SD cards as present on Raspberry Pi, even the Pi 4, don't go beyond ~60MB/s. Older Pis get around ~20MB/s. It's the worst bottleneck of the system. Where do you get that 1 GB/s figure from?
There is a conference going on with Ernst & Young right now about identity verification, an Italian publication is posting verification data on the Ethereum blockchain, for each article. It is mostly for the publisher to protect themselves when people ask about whether they were actually the source, doesn't protect people from sharing fake sources or making it look similar with their own "verification" entries on a blockchain.

Prepare yourself for ads from amorphous organizations with names like The Committee to Re-Establish Democracy or The Project for a New American Freedom. (No idea if these are real, I just made them up.) I suppose it helps to see precisely who is paying for an advertisement, but I don’t think this is actually useful in a real sense.

The only long-term solution is education: foster a sense of skepticism towards all advertising and encourage reading information from a variety of viewpoints. Of course, Google’s entire existence (and having destroyed traditional media’s business model, the media itself) is predicated on ads, so don’t expect anything this lucid soon.

Could you elaborate? I've tried boards from a couple of different vendors and if anything, the proprietary stuff needed for Raspberry Pi has been the most frustrating for me (apart from Android TV Boxes, but hey, we weren't "supposed" to run Linux on those in the first place).

The 3B and 4B have their own different hacks needed to get normal Linux distros running under 64bit, and it's nothing you can expect an average hobbyist user to figure out even with the resources put out by people in the community who have succeeded (unless they just flash some unsigned image containing god knows what uploaded out by some rando on a forum).

iPhone market share is very close to 50% in the US. You can't have a successful app launch in the US without making your app available on the iPhone. Apples policies affect the entire market, especially in the US.

If they're not already a monopoly in the US, then they might as well be since they have the same market control as a monopoly player. Also, a strict majority market share is not required for a company to be considered a monopoly. It's up to the courts to decide. [1] [2] [3]

[1] https://www.ftc.gov/tips-advice/competition-guidance/guide-a...

> Courts do not require a literal monopoly before applying rules for single firm conduct; that term is used as shorthand for a firm with significant and durable market power — that is, the long term ability to raise price or exclude competitors.

[2] https://www.justice.gov/atr/competition-and-monopoly-single-...

> In determining whether a competitor possesses monopoly power in a relevant market, courts typically begin by looking at the firm's market share.(18) Although the courts "have not yet identified a precise level at which monopoly power will be inferred," they have demanded a dominant market share.

[3] https://www.theverge.com/2019/5/14/18618127/apple-pepper-sup...

> The plaintiffs, meanwhile, will argue that these alternatives don’t matter. “The fact that they have a [less than] 50 percent market share of smartphones doesn’t mean they don’t have a 100 percent share of the distribution of iPhone apps — which they absolutely do,” says Rifkin.

I agree that systems don't have to be linear, but for it to be non-linear, it'd have to feed back somehow. Simply buying X times as many iPhones doesn't do it, unless e.g. those iPhones allow them to be Y times more productive, etc.

My point of view goes something like this: some parts of the world _are_ developed, and these already have the various additional productivity multipliers we theorised about above. These can be the baseline productivity level for our calculation. So if the rest of the world were to be brought to this level, the end result is indeed linear, and more or less depends on where we drew the line for "developed". However, it is not 1/1000th of the world population. We could be talking about a 10, or maybe 20x multiplier if we're very generous.

I also don't think historical precedent favours such optimistic numbers, though we could be living in interesting times. However OP's point was, again, a simple introduction / upliftment of more people, not technological multipliers.

Just because something isn't "environmentally important" (whatever that means) doesn't mean you can't optimize it. We need to shift into the mentality of thinking about the environment. Don't slap the hand that's interested in making a difference.
I think that's the decision they are making now, but I think in earlier days, when less was known, ventilators were seen an extreme, but still necessary tool.
You might consider scraping and including US national park service and forest service jobs. While tangentially related to climate change, I would consider them roles that benefit the environment in a meaningful way. You might consider tagging jobs differently: environmental, climate change, etc.

Their goal was testing two versions of Ubuntu (as per the title), that includes every difference between them. Example: Ubuntu 18.04 upgrades Linux up to version 5.3, Ubuntu 20.04 comes with 5.4. There are several other upgrades. They are listed in the first page of the post.
Prior to Apple hardware, I loved my T42... definitely a strong machine on a great platform.

Maybe it is just small sample size, but my mil purchased an HP consumer laptop for ~$600 when I purchased my first MBP in 2010. Hers barely lasted 3 years for hardware and software reasons. My chugged on for 6 years. While the cost per year was similar... the utility was not.

I hope it is better, but during the 1990-2010 period when I ran Windows based systems they inevitably would come to a crawl after a year of use. I would have to completely rebuild them, reinstall the OS and all programs from scratch to return them to utility.

I honestly don't think I have ever done this with an Apple product.

Things like this are tricky to me. YouTube is a private platform, so they can make their own decisions, but any sort of censorship is scary to me.

I honestly don't know where to stand when it comes to issues related to censoring content like this. On one hand, you can limit information we know is false, but restricting spread of information is censoring people, something that is pretty widely regarded as oppressive.

I guess all I can do is wait and see what comes of this.
I have admittedly not much experience with Rust+WASM (I dabbled in Rust though), but enough with C and C++ on top of WASM, and the situtation is really quite similar to C++ (IMHO of course).

Theoretically, C++ also has no "runtime overhead", but start using high-level stdlib features, and suddenly there is a non-negligible overhead. It's possible to cut that down, but that requires a lot of "insider knowledge" of the compiler toolchain and the specific stdlib implementation. In the end it's always about deciding what C++ features to not use to cut the size down, and at the end of that process is a language that's essentially C (no generic containers, no automatically managed memory etc).

And even when using C it is non-trivial to cut down the overhead from the C runtime library functions so that it becomes "competitive" with minified Javascript doing the same thing.

Don't get me wrong, Rust's toolchain integration with WASM is excellent. But I wouldn't call Rust compiled to WASM a contender for killing Javascript.

1) x86 is pretty much always easier and better for (I assume, as you mentioned HTPC, that you mean) game console emulation than other architectures, so if you don't have to have an SBC get a cheap, small x86 machine. Consider used small-footprint business workstations.

2) Raspberry Pi has much better official and (especially) community software support than other SBCs. Things like bluetooth or wifi are usually supported better there, with fewer quirks and breakage, and software's usually more up to date generally. You're rolling the dice with anything else if you're looking for something you won't have to spend a bunch of time fiddling with or fixing all the time.

Apple didn't win because they "tied the whole experience together". Apple won because they're Apple, and an Apple watch is a status symbol. My middle schooler was adamant about upgrading his Android phone to an iPhone last year, because all the cool kids had iPhones.

The GP is saying that the future generations have not to pay back and that the stimulus is necessary now and it will not be inflationary. It's not saying that it's not possible to spend too much and create undesired inflation.
