So funny how the Web goes in circles.
Years ago, we were using images for solid colors, because browsers didn't support transparency. I even wrote a PHP script to generate them in 2009. [1]
Now we're using images for colors again, to go beyond sRGB!

[1]: lea.verou.me/2009/02/bullet…
And it just dawned on me that a lot of folks doing web dev today have never known those struggles. They won't remember when IE6 wouldn't render semi-transparent PNGs and we had to use proprietary .htc scripts to fix it.

christopher.org/png-transparen…
Or hacking semi-transparent backgrounds with filter:progid:DXImageTransform.Microsoft.grad ient(startColorstr=#CC000000, endColorstr=#CC 000000); to emulate background: rgba(0,0,0,0.8);

This was my first talk ever, in 2008, and it was about this very thing: slideshare.net/LeaVerou/color…
Can't say I envy young devs, all these were fun times! But damn I feel old now. 👵🏽

A FOSS tale in 3 acts

Act 1:

Maintainer of popular project from large company (name rhymes with froogle) opens a bug report on one of my smaller libraries, mentioning their project is considering using my lib.

Yay, great news! 🎉Love my code being used on larger tools!
Act 2:

Said maintainer sends huge PR fixing that bug plus changing ALL THE THINGS. Some bugfixes, some just to introduce different tooling.

Yay, great news! 🎉 They want to contribute back! Screenshot from Github PR UI showing 30 files changed, 9,102
As I always do when reviewing a PR, I start by thanking them for their contribution. I then kindly ask them to split the PR in more manageable chunks so they can be reviewed and/or merged independently.

All pretty standard in open source. Github comment from LeaVerou: Hey, thank you so much for wo

Developer priorities throughout their career Image
PS: Very impressed with @excalidraw! I was able to make this in like 10 minutes!

PS2: This was 2 weeks ago. My laptop broke down soon after, and spent all this time in service. I found this chart when I opened it back up, it gave me a smile, and I realized I never posted it. 😊
Some asked about the "Does it actually work" line:

When somebody starts coding, getting the code to work is already difficult enough, so there is no space for other priorities. Writing code that works is THE priority, and whether it's good code is not even a consideration.

Cool #JS algorithm problem that came up in my #WebAlmanac code:

You have an array of unordered DOM nodes. You want to put them in a JSON object that follows their relative containment relationships:

[{element: Node, inside: [{element, inside: […]}, …]}, …]

How do you do it?
Will post my solution tomorrow (unless someone else posts the same one)!
Clarifications: the array with the "inside" key is the descendants of the element on the object it's on, not the ancestors. I.e. obj.inside[0] is a descendant of obj.element.

I love using @GitHubDesktop and if you think it’s only for novices who aren't comfortable with the Terminal, you are missing out.

Thread 👇
1. My top favorite feature of all time: Being able to select individual lines or changes to commit by clicking.
Incredibly useful for splitting commits into meaningful chunks and leaving debug code out! Image
2. Github's "Open in Github Desktop" for seamless clone Image

A story in three acts. 👇

I was drafting a new blog post and suddenly, characters started being deleted, as if Backspace was pressed. I recently got my keyboard replaced, so I wondered if it was a glitch of the new keyboard, so I pressed backspace a few times to get it unstuck.
But characters kept getting deleted. Then I started getting 1111 and ]]]] and {{}}} in my text, as well as more deleted characters.
It was as if someone else was controlling my keyboard!!
I started to panic.
“Am I getting hacked?!” 😱
I switched to another tab, but it continued.
Then I thought, that would be kind of a lame hack. If a hacker could control my keyboard, wouldn't they type something meaningful, like, I dunno "WE ARE HOLDING YOUR REPOS HOSTAGE" or something? 🤔
Where's the fun in "vb C#1121212112}} }}}}]]]]]]]"?

Achievement unlocked: A mini documentary about my life has been published! Whoa. 😳😊

This February, I got an email that a German company, @honeypotio wanted to film a mini documentary about about my life & career path. I thought it sounded fun, so I said yes. Today it's out!
Thank you Guillermo López for flying all the way to freezing Boston in February to tirelessly film this over 3 days and then spend three months editing it. It was a one of a kind experience for me, and I love the result (except how nervous I sound but alas). I'm glad I said yes!
I was v. skeptical about the museum scene since Greece is not a big part of my identity. Guille's vision was to show that disconnect by filming me coding in the Greek section of a museum, oblivious to the exhibits. Not sure if that's conveyed, but it's certainly a bold scene! 🤷🏽‍♀️
