Comment x32 flopped (Score 2) 21

The larger address space can be useful in some applications

Such as high-resolution image editing and high-definition video editing. Compared to a web browser, these aren't quite as amenable to splitting an application into numerous "content processes," each with their own separate 2 GB RAM.

but most applications are already bloated and having bigger pointers hasn't improved matters for this bloat problem.

For a while, Linux supported an x86-64 ABI called "x32" that limits each process's address space to 2 GB so that more pointers will fit in the processor's data cache. It didn't become popular, in part because of a need to load three versions of the system libraries: 32-bit i686, x86-64, and "x32". In addition, porting x86-64 applications to use less pointer-heavy containers gave most of the cache advantage that "x32" would have provided. This includes switching from linked lists to gap buffers (or other dynamic arrays), from B-trees to T-trees, or from pointers to indices in a pool. Rust in particular has encouraged use of appropriately sized indices as a workaround for the borrow checker.

For systems that want to access more than 2GB-4GB of physical RAM, there has long been PAE/PSE-36 that permit mapping 64GB physical address space to a 32-bit virtual space.

There's a widespread misconception that a 32-bit operating system is limited to 3 GB of physical RAM. I think this comes from Microsoft's practice of requiring drivers for 32-bit Windows Server to support PAE as a condition for certification, but not drivers for 32-bit Windows desktop. I seem to remember 32-bit desktop Linux being more PAE-friendly. PAE and content processes are how Firefox for 32-bit Linux managed to hang on this long.

So the service worker installs the entire Grab site to you phone? Grab handles food delivery, grocery delivery, package delivery, ride sharing, financial services, etc.. That seem extremely inefficient to load every single function to your phone just because you visited their website.

Each function could be loaded the first time the user uses it. The device has to be online to query what is in stock at any given moment anyway. And I'd be interested in others' speculation about why the client side of the most widely used functions can't all fit in (say) 5 MB, which is twice the size of Doom.

You suggested a solution that Grab, Doordash, Uber Eats, Instacart, Favor, Grubhub, Postmates, etc. do not use. I pointed out maybe these companies know way more about their needs and solutions than you. Do you accept that?

I accept that, adding a clarification that I suggested the solution for the purpose of asking other people what these companies might know that I don't.

If they were cheating by any significant amount, we would know because emissions are visible from space. This article has an image showing how emissions can be traced to individual sources, even: https://theconversation.com/tr...

Satellites can also see reduced smog over China.

We can also see the massive solar and wind installations from space, or you can just get a visa and go look at them for yourself. Plenty of people have. Take a PM2.5 and CO2 monitor with you, for good measure.

Obviously exponential growth won't go on forever, but we are a very, very, very long way from saturating the available demand or land available for renewables.

Deployment will keep accelerating as costs continue to fall and people see the benefits of producing their own energy. The payback time on the investment has been steadily falling for decades.

Is it that different to what some Western countries have? The US is a two party system. The UK is too, despite recent gains by smaller parties.

Speaking for the UK, the choice is between hard and soft Thatcherism. That's not much of a choice. A vote for anyone else is usually wasted, not counted at the national level.

That is deliberate policy too. No government will change it because they think they can win the next election and gain 100% of the power, rather than a more representative system that distributes it in a democratic way.

Submission + - Europe's cookie law messed up the internet. Brussels wants to fix it. (politico.eu)

AmiMoJo writes: In a bid to slash red tape, the European Commission wants to eliminate one of its peskiest laws: a 2009 tech rule that plastered the online world with pop-ups requesting consent to cookies. European rulemakers in 2009 revised a law called the e-Privacy Directive to require websites to get consent from users before loading cookies on their devices, unless the cookies are “strictly necessary” to provide a service. Fast forward to 2025 and the internet is full of consent banners that users have long learned to click away without thinking twice.

A note sent to industry and civil society attending a focus group on Sept. 15, seen by POLITICO, showed the Commission is pondering how to tweak the rules to include more exceptions or make sure users can set their preferences on cookies once (for example, in their browser settings) instead of every time they visit a website.

I wouldn't be so certain that China's model won't come to dominate eventually, because we don't seem to be able to fix our democracies. There are clear flaws that are being exploited now, and the inability to adequately deal with climate change while China races ahead is both a moral and economic failure.

I'd very much prefer democracy to be the winning model, but it won't just happen by itself. Look at the rise of populist right wingers - people will vote away their rights and prosperity in exchange for nothing more than rhetoric, if they think that democracy isn't delivering for them.

WebP only got an RFC (9649) in November 2024. JXL hasn't even got that far.

I hope JXL does catch on, but until Chrome supports it that will not happen. Maybe now that it's required for PDF display, Google will be forced to re-adopt it.

To be fair I think the reason they dropped support for JPEG XL is because the reference C library is crap, and last time I looked none of the alternatives were very mature. Hopefully things have improved by now.

At least China has now proven that not only can an economy thrive with renewable energy (remember all the hand wringing about the lights going out and destroying manufacturing?), but it can in fact be a hugely lucrative market.

The other big emitters should be looking at China with envy, and seeking to catch up before they are left behind with only expensive fossil and nuclear power.
