@LeaVerou I think Firefox's behaviour is right according to the DOM spec. https://t.co/CpPBDeebVL
Retweeted by Lea Verou @johnste_ @ziyunfei @leaverou One callback but with 2 records, right?Just wasted hours due to this, beware: Firefox fires mutation observers even when the content didn't change Test: https://t.co/a0JyEvgxnu @Hashnoder FYI, CSS3 is a made up term. It's CSS 2.1 broken up into different modules, per @LeaVerou's book. https://t.co/QzSFQKEOk2

@efrikio @diana_aceves_ @nabaroa @sazzy it's a sexist diminutive. You don't refer to men as boys. Stop being offended and educate yourself.

@AMehdiW I love cheese but you gotta send me an email to discuss the specifics :) @efrikio @diana_aceves_ @nabaroa @sazzy please don't refer to grown up women as girls.Apparently the average web page weight is now the same as the original Doom.

@GitHubHelp Is there any way to ask for an unused username? It's registered 3 years ago, no repos, no info, completely empty profile. @oscargodson @avraamakis With the same logic, Notepad is better than a word processor, because the word processor needs more code. @oscargodson @avraamakis While the parser is larger, it's still a pretty simple and unambiguous format to parse, just less than JSON. @oscargodson @avraamakis First time you actually made it clear you're talking about the amount of code in the HJson parser, not HJ code […] @GrumpyWizards White space is removed to save space. There's nothing inherently evil or heavy in it. \n and , have exactly the same weight. @oscargodson @leaverou @avraamakis I’m suggesting you're making strawman arguments here. What do large code bases have to do with Hjson? @avraamakis @oscargodson The fact that relaxed syntax is easier for humans is not a new idea. It's why HTML succeeded and XML did not. @oscargodson @avraamakis Again, do you actually have any specific arguments against Hjson or just general vague fears about lax syntax? @oscargodson @leaverou @avraamakis A link to a tangentially related paper from 40 years ago doesn't automatically prove your point. @GrumpyWizards You just leave the line breaks. One line break has exactly the same weight as 1 comma. @AllThingsSmitty But did you actually read the book? :PDreamed I was fighting with my bro and @LeaVerou showed up and said, “Guys, stop fighting and read my #CSS book”. And then there was peace.
Retweeted by Lea VerouWow this is soooooo needed. Scroll anchoring fixes the weird mobile web page shuffle. Now in Canary / Dev. https://t.co/nzsgLWZPfv
Retweeted by Lea Verou @oscargodson @avraamakis Your experience is neither a logical argument, not a proof of your claims, and 10 years is not even that long. @GrumpyWizards A line break is 1 character. A comma is 1 character. Not sure how one is smaller than the other. @oscargodson @leaverou @avraamakis How so? Do you actually have any concrete examples or just general fear of progress? @craigfrancis The parsing issues in HTML are about invalid HTML, which is still parsed. Not because of relaxed syntax. @LeaVerou interesting watching from afar how ux/design can enrage/harm a user, and then be saved by human/customer engagement. fullcircle

.@Sprintax_USA After that, I got excellent personal service, my taxes were done quickly & checked by a human. I totally recommend them now!So @Sprintax_USA contacted me today. Turns out the live chat person was clueless and they DO support income code 12. It was just a UI issue.You will be able to do addEventListener('type', handler, { once: true }) natively instead of removeEventListener! https://t.co/hvg1cVC4JA

@avraamakis Disambiguation doesn't seem to be an issue, so why not?HJSON: The Human JSON. More forgiving syntax, comments, unquoted strings https://t.co/jSENjS0EA3 Awesome! I want native support! @robwierzbowski I cannot use TurboTax because I'm not a US citizen/permanent resident. @KevinLozandier they were :) hopefully the resulting paper gets in! @KevinLozandier no, it is not, sorry! @xkit @Sprintax_USA what if I hadn't noticed?? This service is DANGEROUS..@Sprintax_USA = crooks. It lets u enter unsupported income codes & SILENTLY IGNORES THEM, making u liable for fines https://t.co/3DGSI3oYYj

@kevinmarks no, tell me! @MaxArt2501 @aerotwist Exactly my worry about Houdini. Great initiative, but often used as an excuse to avoid implementing anything. @aerotwist @LeaVerou Houdini looks awesome to no end, but I hope won't be an excuse to stop developing CSS features (as this should be IMO).
Retweeted by Lea VerouGoogle autocomplete brings the harsh realization that none of us is the unique snowflake we think. Any random search has been tried before. @SteveRaskin @stelian good. Don't do that! @aerotwist yep, fortunately @LeaVerou has your back: https://t.co/cY571nUc4h . Links to relevant safari/chrome/edge/ff bugs at the bottom.
Retweeted by Lea Verou @aerotwist Spec's been proposed long ago, @LeaVerou created a very good polyfill. It's time to evolve things in browsers, don't you think?

Oh, hey, a box with text and a border on a site using flat design. Is it just text? A textbox? A button? WHO THE FUCK KNOWS.
Retweeted by Lea VerouAlso, flat design? oi. fucking hell. Flat design, also known as removing all indicators of what something is.
Retweeted by Lea Verou @SincerelyTumblr Applies to LaTeX too.using microsoft word *moves an image 1 mm to the left* all text and images shift. 4 new pages appear. in the distance, sirens.

@gumnos @creativecloud Actually, the 2nd support guy (Manoj) was awesome. He worked hard for 2 HOURS on my computer trying to solve it. @AdobeCare it's not that simple. I'm in a remote support session for an hour now. Poor guy still can't solve it but is trying. @_juanmnl @creativecloud Unfortunately, it's not like there are any real alternatives to Photoshop or Illustrator. :( @AdobeCare Not a very smooth experience so far. More like a horror movie, esp. since I'm on a deadline. :( @AdobeCare I created a new account. Now struggling with Photoshop install issues, as it fails at 42% :(. Tried the live chat, still waiting.Apparently, @creativecloud thinks people never move countries. Impossible to change region. Support suggests creating a new account. #FAIL

I was trying to be helpful. Ok, ok, you're not doing it wrong! Sorry if I offended you™ @marijnjh No worries, that's exactly how we do plugins in @prismjs too :) @christopherdan You were on the wrong site. I should delete it at some point. @marijnjh Thanks! Re: more complex, eh, it's better than nothing and I'm good at pattern matching :) @chriseppstein 2. Gourmet food isn't usually too fattening. Portions are small, and they're not trying to cut costs by bloating with carbs. @chriseppstein 1. Counting calories is doing it wrong. All research points to carbs being the bad guy. @marijnjh Thanks! Are you aware of any plugins doing that or anyone that wrote something describing the API? Can't find much on plugins.let x = (() => { for (var i = 0; i < 5; i++) { try { return i; } finally { if (i != 3) continue; } } })(); console.log( x ); // ? #js
