interesting mentions of the and tags. I have a modern app that makes use of these properties for making gif's. blink will make any content in the gif flash on the canvas and marquee will move it side to side : https://imgur.com/rgHrsoa

and can be pretty much replicated with CSS animations — there's no need for the tags anymore.

You have to jump through a lot of hoops to replicate blink in css. https://stackoverflow.com/questions/13955163/imitating-a-bli...

Because you'd have to download an app like this and then trust that it won't install malware or spyware or do anything else malicious.

Why would you use browser-based video editing over desktop-based free software, where you can read the source (or listen to someone you trust who has read the source) to make sure it's not doing anything malicious? Besides the fact that it might be easier/simpler for very small projects.

Because then it wouldn't be "cool".

So many of the projects I see mentioned here are neat hacks, but that's really about it.

People writing a complete operating system for an 8 bit micro made of discrete chips? That's neat, but not really useful, and most people won't ever take the time to boot it once.

An FPGA that runs web assembly code? That's nifty, but if we want high performance we probably won't use web assembly to do it.

You invented a completely new language that has all the features of C but none of the things that are annoying? We'll add it to the list of C-like-but-not-annoying languages.

Found a great new way to estimate how much capital you should try to get when creating a start-up to sell your all-natural soap products in California? That's great for you... a little bit niche for the rest of us.

You re-implemented emacs in python? That's a really impressive technical achievement. No one will ever surpass you in either emacs implementation or python hacks. Also, no one will ever use it.

Same thing with Hackaday... lots and lots of "cool" projects where neither the creator nor the site mods seem to realize something is just a nifty project, and not the salvation of the world.

So end users should read all the source code of every piece of software they intend to use before using it instead of using a proven jailing method?

It's funny this came up. I've been doing webstuff and getting paid for it since about 1996 or 1997; imagemaps were a pretty big deal back then. Recently, I found myself thinking, "How do they do that these days?" I have gotten out of the webbish stuff and even before that, I tended to stick to the tried and true. I don't think the need for something very much like imagemaps will ever go away. The lure of arbitrary po…

the modern web just doesn’t do that, though. I don’t think I’ve seen a clickable polygon in the last 15 years

Arbitrary polygons are, after all, not that easy to click in general.

The author seems to be have written this post based on work for an in-browser video editor ( https://videoinu.com/editor ). It runs completely on the client-side, so all the editing, previewing, rendering, and exporting is done using web technologies. Of course, it's not comparable to a professional editing tools but nevertheless that's very impressive achievement in my opinion!

> It runs completely on the client-side, so all the editing, previewing, rendering, and exporting is done using web technologies. If so, why just not use native desktop/mobile video editor app instead?

This would be accessible anywhere on any computer hooked up to the internet, even potentially a phone, tablet, raspberry pi, your grandma's computer, etc.

Many programs that don't need low level access like spreadsheets, pdf readers, word processors, image editors, etc.could be made into single page html files that would both be sandboxed and cross platform.

Image maps were great. I used them for a site's nav that needed some slight visual flair (item entries had to be diplayed at a slight angle with a custom font). To reduce the bandwidth, the entire nav's text was a single image with transparency. Then the backing would be either a red or green angled rectangle. The text had a mapping over it that would change the background rectangle depending on what area you hovered. It made for a great effect.

I remember seeing image maps for the first time as well. I can't remember exactly what they were for (possibly the Yahoo logo when it had circular buttons around it), but I distinctly remember the feeling of being able to click on an area of an image and something different happening. It floored me at the time because it was, in my mind, when Dorothy opened the door to Oz and a huge, beautiful world just appeared bef…

I couldn't agree more with your feelings, it was beautiful at the time. I remember I spent hours visiting websites with JS snippets, to do simple things, the web felt so much amateur and collaborative. Seeing it now through the times, I think the difference was that to create an amateur website, you don't need to understand a lot of techs, just HTML and how to use a FTP software. Now everything seems much more comple…

You still can go the route of not knowing a ton of tech to get a site up and running while still having full agency over the HTML/etc. Just pick up a service like bluehost shared. Hell, at work we even have one for odd tasks and easily-accessible FTP needs and one-off sites or documentation pages.

I do remember getting to play with Dreamweaver back then, though. It felt so high tech compared to Notepad and FrontPage Express and all that. All the "cool" sites had image maps and as a kid it was tough to understand how they worked. I did something similar to you, but usually copy and pasted from a web site then changed the image out and kept tweaking by trial-and-error until I got the result I wanted.

Nostalgia is a strong drug haha

I used to love image maps: really useful for adding hotlinks and hover effects to images. Sadly they can't deal with the modern responsive web - though there exist some Wordpress plugins to help overcome that issue. This CSS article[1] goes into details about alternative approaches. It mainly seems to be SVG, or CSS clip paths. I've used (and like) SVG; CSS clip paths are foreign territory to me - has anyone used the…

I do like the example with the pins/labels on an image. Seems like it would be useful for something like Wikipedia or recipes, etc.

Is it accessible-friendly?

Back in the day, finding good documentation was a lot harder. Not having MDN is a bigger deal than Dreamweaver vs. Notepad++.

They're x, y pairs for the top-left and bottom-right corners of the rectangle. They're coordinates in the fourth quadrant of the Cartesian plane (i.e., with the origin conceptually in the top-left corner), which is also the way coordinates are given in most windowing systems (including X). This is more obvious when using the "poly" attribute rather than "rect," where you can have an arbitrary number of x, y pairs (an…

something I always wondered since the age of programming mode 13h, is the use of the fourth quadrant so that loop would fill video memory in the order the scan line goes reading it?

This is pretty much it. Scan lines are numbered from the top down, as they happen, everything else is numbered accordingly.

The real question is why scan top down and not bottom up? (I don't have any idea). Horizontal scan lines makes sense given a wider than tall screen, because it results in fewer scan lines, lowering the frequencies required ( a bit). Wider than tall makes sense for TV given common movie film aspect ratios and computer monitors started as TVs with different control circuits and cases.
