A great little history lesson from Amber—ah, Firebug!
Amber documents a very handy bit of DOM scripting when it comes to debugging focus management:
Well, this is a grim collection from Dave:
There are some cases where even using plain ol’ HTML causes accessibility problems. I get frustrated and want to quit web development whenever I read about these types of issues. Because if browsers can’t get this right, what hope is there for the rest of us.
It’s worth clicking through each link he lists—the situation is often much more nuanced than simply “Don’t use X.”
That unusual behaviour I wrote about with the Web Share API in Safari on iOS is now officially a bug—thanks, Tess!
Cassie and I were swapping debugging stories. I shared the case of the 500 mile email with her. She shared this with me.
I love this example of paying it forward:
The latest version of Chrome is removing seams by messing with the display of the URL.
This is a bug.
Google hijacking and hosting your AMP pages (in order to pre-render them) is pretty terrible for user experience and security:
I’m trying to establish my company as a legitimate business that can be trusted by a stranger to build software for them. Having google.com reeks of a phishing scam or fly by night operation that couldn’t afford their own domain.
A great long-term perspective from Rachel on the pace of change in standards getting shipped in browsers:
The pace that things are shipping, and at which bugs are fixed is like nothing we have seen before. I know from sitting around a table with representatives from each browser vendor at the CSS Working Group how important interop is. No-one wants features to be implemented differently in browsers. This is what we were asking for with WaSP, and despite the new complexity of the platform, browsers rendering standard features in different ways is becoming increasingly rare. Bugs happen, sometimes in the browser and sometimes in the spec, but there is a commitment to avoid these and to create a stable platform we can all rely on. It is exciting to be part of it.
Jake’s blow-by-blow account of uncovering a serious browser vulnerability is fascinating. But if you don’t care for the technical details, skip ahead to to how different browser makers handled the issue—it’s very enlightening. (And if you do care for the technical details, make sure you click on the link to the PDF version of this post.)
A good developer…
- follows the KISS principle (and respects YAGNI)
- knows how to research
- works well with others
- finds good developer tools
- tests code
I like the idea of “design bugs”:
Every two weeks or so, a group of designers would get together for a couple of hours to fix what we called “design bugs.” These were things that didn’t hinder functionality and wouldn’t have been filed as an engineering bug, but were places where we were using an old component, an existing one incorrectly, or a one-off alteration.
Rachel is maintaining this (short) list of browser bugs with CSS Grid, inspired by the excellent Flexbugs.
Grid shipped into browsers](https://gridbyexample.com/browsers) in a highly interoperable state, however there are a few issues - let’s document any we find here.
I was just helping out with some debugging at work and it reminded me of this great talk/post by Remy:
- Replicate: see the bug
- Isolate: understand the bug
- Eliminate: fix the bug
A list of known bugs (and workarounds) in flexbox implementations. This is going to be handy to refer back to.
Regular expressions are my kryptonite. I’m rubbish at them and I can never keep the vocabulary in me head.
Mark recommended this tool so I’m going to give it a go the next time I have to resort to regex.
Kenneth has isolated Chrome’s dev tools into its own app. This is a big step towards this goal:
Why are DevTools still bundled with the browsers? What if clicking “inspect element” simply started an external DevTools app?
With DevTools separated from one specific browser, a natural next step would be making the DevTools app work with other browsers.
