F*** me!

The owner of whirlpool.net.au commenting on my comment.

I am replying because of the huge respect I have for the work.

Yes, I am seriously asking with a straight face.

Yes, I know how to pirate. I’m from this planet. :-D

Pirating, and jumping through hoops to do things certain vendors didn’t want done, was fun while I was learning. And educational. Super educational, in many respects.

But it is not fun anymore for me. There are other things these days that can get me banging my head against walls, and they are, in total, more fun and more educational.

What plenty of ways?

How can I run a macOS virtual machine LEGALLY on my Linux or Windows machine?

I think pjmlp is just being contrarian.

First, the Microsoft browser these days is Edge, not IE. IE is dead.

Second, if you want, or wanted in the past, to test on Internet Explorer without a Windows computer, you could just virtualize Windows. Windows can be legally virtualized on any hardware and on any host operating system.

Starting from 2013, you didn’t even need to pay for a Windows license to do that:

I know of the solutions. I use a few of them.

I have multiple Playwright webkits on both Windows and Linux. I have Epiphany on Linux (not 100% same webkit). I have subscriptions for testing on real hardware.

This is why it seems to me that Apple does not really care about web developers.

But does Apple really care about web developers?

How do you test on Safari if you don’t have Apple devices?

How difficult can it be for Apple to make barebones virtual machines with just Safaris?

What chrisweekly said:

Configuring webpack, mostly. :-D

That’s not a dig at webpack: Those tools are super complex, and hiding complexity from the user is not easy. But it seems that with Vite we finally got there.

الشهر الماضيdiscuss

I love Vite, when I don’t forget it exists in my projects. It took things that made you feel mentally deficient and made them almost zero-config.

This news does not make me happy.

Same with the news about Astro earlier this year.

I know it must be good for the people how have made the projects (why else would they chose to do it?) but there is something in those acquisitions that makes me uneasy.

That is not necessarily proof.

Sometimes I am too lazy to think of a good commit message, so I have a custom command that tells the assistant to do this:

Commit umstaged changes with a nice clean message summary and no full message.

By default, Claude Code co-signs those commits (which I do not like at all as a default).

Websites do care about the UA. They don’t care, at least most don’t care, about the User-Agent string. That is different.

About an element that gets rendered into native menu controls, I am not sure. I haven’t been following closely for the last two or three years. But that seems like a good candidate for a native element. 9 out 10 websites need it.

قبل 5 أشهرdiscuss

Some of the stuff we have been adding since then is GOOD though.

Some examples:

We now have to accommodate all types of user agents, and we do that very well.

We now have complex navigation menus that cannot be accessible without JavaScript, and we do that very well.

Our image elements can now have lots of attributes that add a bit of weight but improve the experience a lot.

Etc.

Also, things are improving/self-correcting. I saw a listing the other day for senior dev with really good knowledge of the vanilla stuff. The company wants to cut down on the use of their FE framework of choice.

I cannot remember seeing listings like that in 2020 or 2021.

PS.

I did not mean this reply as a counterpoint.

What I meant to say is, even if we leave aside the SPAs that should not be SPAs, we see the problem in simple document pages too. We have been adding lots of stuff there too. Some is good but some is bad.

But how does that work?

Does Cloudflare force firewall rules for those who choose to use it for their websites?

If the tool that does the crawling identifies itself properly, does Cloudflare block it even if users do not tell Cloudflare to block it?

Firefox could (should?) be better in several aspects but it seems excessive to say it is pretty irrelevant.

It has 4.5% market share in Europe, 9% in Germany (statcounter numbers).

It is the browser that got the Google Labs folks to write a Rust jxl decoder for it, and now, thanks in part to that, Chrome is re-adding support for jxl.

You can be unhappy with Firefox (I often am myself), and Firefox HAS lost relevance, but can you really say it has become pretty irrelevant?

I didn’t pay close attention to the domain and I thought it was the other one:

https://moderncss.dev/

One of the best educational resources for modern CSS.

BTW, one of the reasons I love modern CSS is front-end performance. Among other things, it allows you to make smaller DOMs.

I talk about a modern CSS technique that does that here:

https://op111.net/posts/2023/08/lean-html-markup-with-modern...

It is an idea I started playing with when custom properties landed in browsers, around 2016 or 2017? Around 2021 I started using the technique in client sites too.

Now I want to write a 2026 version of the post that talks about container queries too. The technique becomes more powerful if you can rely on container queries and on the cqw unit. (You cannot always. That stuff is still new.)

For an example of the convenience cqw offers if you can rely on it, see the snippets I have in this:

Thank you!

> The folks who crawl more appear to mostly be folks who are doing grounding or RAG, and also AI companies who think that they can build a better foundational model by going big.

But how can they aspire to do any of that if they cannot build a basic bot?

My case, which I know is the same for many people:

My content is updated infrequently. Common Crawl must have all of it. I do not block Common Crawl, and I see it (the genuine one from the published ranges; not the fakes) visiting frequently. Yet the LLM bots hit the same URLs all the time, multiple times a day.

I plan to start blocking more of them, even the User and Search variants. The situation is becoming absurd.

I don’t believe resips will be with us for long, at least not to the extent they are now. There is pressure and there are strong commercial interests against the whole thing. I think the problem will solve itself in some part.

Also, I always wonder about Common Crawl:

Is there is something wrong with it? Is it badly designed? What is it that all the trainers cannot find there so they need to crawl our sites over and over again for the exact same stuff, each on its own?

Hey, tasty_freeze!

The motivation behind the benchmarks was to understand what are the options today for optimizing the types of image we use PNG for, so I used the same set of images I had used previously in a comparison of PNG optimizers.

The reason the set does not have photographs: PNG is not good at photographs. It was not designed for that type of image.

Even so, the set could do with a bit more variety, so I want to add a few more images.

قبل 6 أشهرdiscuss

Yeah.

Numbers for decompression speed is one of the two things I want to add.

The other is a few more images, for more variety.

I published some benchmarks recently:

https://op111.net/posts/2025/10/png-and-modern-formats-lossl...

I compare PNG and the four modern formats, AVIF, HEIF, WebP, JPEG XL, on tasks/images that PNG was designed for. (Not on photographs or lossy compression.)
