Should I be worried? The three most-disliked programming languages in Stack Overflow’s latest blog post are perl, delphi, and VBA. And those three languages all have a special place in my heart. Oops…
Perl I have been enjoying recently and VBA is most of my day-to-day coding (since what they actually pay me for is driving MS Office). Delphi remains the only piece of software I have ever bought based on one marketing presentation. After QBASIC, I moved up to Turbo Pascal 6. When Delphi came out, I only had to see it on screen to be hooked.
Delphi is also what taught me that the magic in a toolchain is really the linker. As I was learning C, I was able to write Windows programs using my DOS version of Turbo C++, linked with the Delphi linker.
Excerpts from Stack Overflow’s analysis follow.
A custom tea timer for https://smithtea.com/pages/know-your-tea#brewing-instructions:
A message I have found myself typing frequently on Stack Overflow: 🙂
As compressed by https://jscompress.com/; non-minified is:
var qsel = document.querySelector.bind(document);
var edit_link = qsel('.edit-post');
var add_comment = qsel('.js-add-link.comments-link');
var textbox = qsel('textarea[name="comment"]');
"Welcome to the site! Check out the [tour](https://stackoverflow.com/tour) "+
"and the [how-to-ask page](https://stackoverflow.com/help/how-to-ask) for "+
"more about asking questions that will attract quality answers. You can "+
"[edit your question](" + edit_link.href + ") to include more information."
textbox.scrollTop = textbox.scrollHeight;
These are the first two I have written. I hope they are useful to you, or serve as helpful examples if you are writing your own bookmarklets!
Technology makes our lives better to the extent we don’t have to think about it. Robert Pirsig makes this point in Zen and the Art of Motorcycle Maintenance, and it’s still true: technology that draws attention to itself has failed (except to a very hard-core audience of which I am probably part 😉 ).
For the last two years, I have been using Google Chrome to view PDFs at work. Dozens a day, usually with at least five open at a time. For the last two years, every time I have rotated the view clockwise or counterclockwise, my page has shifted off-screen and I have had to scroll to get back to it. Has that stopped me from doing my job? No. Has it drawn undue attention to the underlying technology? Yes. Very yes.
I cannot express my delight at finding, after a recent Chrome update, that I wasn’t the only one with this problem — and that it has been fixed! I rotated my PDF and reached for the scrollbar, but then I noticed the underlying technology in a good way: I was still looking at the same page I had been. Now each day is a bit smoother, and my job is a bit easier, because the fix has reduced, rather than increased, my mental workload.
My sincere thanks to everyone involved in pdfium bug 116297. Special thanks to thestig at chromium.org for making the fix! If you read this, thestig, please know you have succeeded.
Note to programmers: sometimes small fixes are big wins. It took thestig two lines of code to save me several minutes of wasted effort per work day, every work day, possibly for the rest of my career. Fix the small things — your users will thank you!
Celebrate with me — I just earned my first tag badge on Stack Overflow! It’s for the C language, so that means I’m some kind of C expert, right? … 😉
Edit: And WordPress tells me this is my 50th post on this blog, so it’s a good day for milestones!
Every piece of technology is built to work provided its assumptions hold. Every piece of electronics, for example, assumes it will have power. No power => no function (as famously noted by The IT Crowd). By breaking those assumptions, you can do some amazing things:
In this video (~36 min), scanlime finds exactly the right microsecond to drop the power supply — just enough! — to cause the processor built into a graphics tablet to dump its entire memory over a USB connection. This is not a function the tablet was supposed to provide!
By painstakingly, scientifically defeating the assumption of a stable power supply, the tablet’s firmware control program, intended to be kept within the tablet, becomes available to inspect. And, as scanlime points out at the end of the video, that control program may well open other doors. Analyzing the control program may reveal other assumptions the tablet makes — assumptions that can be broken to change the tablet’s function to what she wants it to be.
Every system is only functional, secure, reliable, or any good at all, as long as its assumptions hold. Whenever you think about the latest gizmo, don’t just ask what it will do for you. Ask what it won’t do for you when you least expect it — when the gizmo assumes wrong.
This got lost in my drafts folder. Enjoy! (I did!)

The “Type Theory” bookmarks at @party 2016
I watched the stream of the compos at @party 2016 and enjoyed the video of Type Theory by nom de nom and Tymbeusz (YouTube). Until now, though, I had no idea what the bookmarks looked like! Thanks to jmph and the @party folks for putting a scan on scene.org. In case you don’t want to download the >20MB archive including the video, here’s the scan. The NFO file is below. The hand-written serial number on the bookmark is out of 64 they printed.

We printed @Party bookmarks on a c. 1895 letterpress with a 3" x 5"
chaise: The Kelsey Excelsior. We used a well-known font, Goudy
Old School. We did an edition of 1000000 bookmarks (in binary).
The type was composed and set by hand, printed by hand, and the
printed cards were cut into bookmark shape by hand.
Why no @ on the card? We didn't have that piece of type.
