Comment Reflections on Rusting Trust (Score 1) 65

The main reason that people worried about a spec in the past was to avoid vendor lock-in. An implementation which is available under a public license is a good solution to that problem also.

Even apart from costs associated with proprietary software, the other reason to avoid vendor lock-in is to avoid self-propagating backdoors in the compiler. Ken Thompson described how to make such a backdoor with C in his 1983 "Reflections on Trusting Trust" speech. David A. Wheeler described "diverse double-compiling", a defense against compiler backdoors that relies on the existence of independent implementations of a language. Stable Rust doesn't have that because it's such a moving target, with widely used programs relying on language and library features less than half a year old.

Comment GCC vs. LLVM (Score 2) 65

GCC has tended to support more historic instruction sets than LLVM. If a device's instruction set is supported by GCC and not by LLVM, it can run programs written in C, C++, Fortran, and other languages supported by GCC. It can also run programs in an interpreted language whose interpreter is implemented in a language supported by GCC, such as Python and PHP last I checked. It cannot build programs written in languages supported only by LLVM and not by GCC, such as latest stable Rust. What keeps gccrs (the Rust front end of GCC) from entering production is that the Rust language is still a rapidly moving target, with popular programs routinely requiring features added to the language or the standard library less than six months ago.

Comment Re: Cloud computing is one the dumbest ideas ever. (Score 1) 76

I would venture the #1 reason PWAs are not used is they require a constant internet connection.

The service worker API is explicitly designed to avoid downasaurs in "offline-first" use cases. It acts as a proxy to serve the shell document, style sheet, scripts, and stale data, even without an Internet connection. That's why I asked what obstacles there are other than a downasaur.

Again, have you presented your ideas to Grab?

I have not presented my ideas to Grab because I am not a user of Grab. I would imagine that most readers of Slashdot are likewise not users of Grab.

I was expecting someone who has used the product to help others in this discussion understand why Grab probably chose and continues to choose to develop iOS apps instead of PWAs. The answers might have taken the form:

A. PWAs weren't capable enough 12 years ago for X, Y, and Z reasons, are now, and the engineering resources to port the native app to a web app would exceed the cost of acquiring and maintaining Macs capable of running the latest macOS
B. PWAs still aren't capable for X, Y, and Z reasons

Comment Depends on what Apple lets PWAs do (Score 1) 18

The right decision would be for a news site and storefront to have platform-agnostic web sites, not applications you have to install.

And the right decision would be for phone operating system publishers to provide functionality in the included web browser to let a website act as a progressive web application. Safari for iOS has a history of lagging behind other platforms' browsers in PWA features.[1] This is particularly evident with respect to what the browser allows websites to do in the background. For example, Apple implemented Push API seven years after Mozilla did, and it requires the user to add the website to the home screen to enable PWA features.[2] Do you want Nintendo Music to pause when you switch to another application? Or if you've chosen to let Nintendo's website notify you when something becomes available, do you want to miss the notification if Safari suddenly decides that your domain's notifications shall be silent (without vibration, without sound, and at the bottom of the list)?

Comment Re:Very few things are cheaper in the "cloud" (Score 1) 76

But for compute, or storage, or bandwidth: on-prem will always win in cost.

With two exceptions I can think of. Correct me if I'm wrong, but as I understand it:

1. For lightweight web hosting, a low-end VPS from a company like DigitalOcean is likely to be less expensive than upgrading a home office from home-class home Internet to business-class home Internet to unblock inbound ports 80 and 443.
2. SMTP is still an old boys' club, with major mailbox providers (such as Gmail and Outlook) blocking connections on port 25 from on-premise IP addresses as likely sources of spam.

Let me know when they start making *autographic* 120 film again. I have the camera, and am dying to shoot a roll!

The last rolls were apparently made in 1932. The cameras had a flap that could flip up and allow writing directly onto the film with a stylus. When you see handwriting on an old picture print, it was likely shot on autographic.

[and, yes, in fact my autographic camera *does* have bellows!]

Comment not really electrolux (Score 1) 123

That Electrolux isn't really an Electrolux.

a couple of decades ago, in one of those weird corporate maneuvers, it sold the name, and now sells its vacuums under another name, while the buyer sells non-electrolux as Electrolux.

So what she knows of Electrolux from the late 20th and early 21st centuries no longer applies.

But, yes, they were very good and lasted forever. Also extremely pricey.

Comment Re:A word of warning about "roof paint" (Score 1) 52

We had to have our entire roof reshingled after a particularly bad storm.

It turns out that of the various colors, the lightest (or 2?) was actually energy star rated. So we took it.

It turned out to be worth about 2F inside as compared to the prior black shingles.

We got another 2F when we replaced the swamp cooler--the newer model had an 18" pad instead of 12".

Between the roof and the bigger pads, we only had a single non-monsoon season day where we had to switch over to AC this summer--in Las Vegas!

(I'm going to miss the swamp cooler when we move, but they're apparently not allowed in new construction. I have no idea when the cutoff was)

Comment You still need a domain name (Score 1) 35

I would also consider allowing an option to blindly accept self-signed certificates on private IP ranges to encourage HTTPS for people too lazy to use Let's Encrypt or something like that

Does "too lazy" include no budget for a domain name before the proof of concept is complete? Let's Encrypt doesn't work unless you buy a domain name and keep it renewed. To satisfy a DNS-01 challenge, you need to host the domain's DNS at a provider with an API that an ACME client can use. To satisfy an HTTP-01 challenge, you need to be on an ISP that allows incoming connections on port 80. A lot of home ISPs block inbound port 80 because they use carrier-grade network address translation (CGNAT) or want to upsell business-class service or both. Nor does HTTP-01 work for wildcard certificates.
