Another great read on futexes is Ulrich Drepper’s paper "Futexes Are Tricky" [1].

New comment by wizerno in "Show HN: Nissan's Leaf app doesn't have a home screen widget so I made my own"

Does anyone else miss the functionality of the Android WhatsApp widget [1] on iOS? Being able to read messages without sending read receipts via the widget is a great feature. The iOS notification 'peek' is a clumsy substitute.

Is this a fundamental limitation of iOS widgets/APIs, or just something WhatsApp hasn't implemented? Curious if others have found better ways to handle this on iPhone.

New comment by wizerno in "Gregglogger"

wizerno — Thu, 21 Nov 2024 02:35:16 +0000

It looks like you're correct -- Gregglogger relies on pynput, and its behavior on macOS aligns with the library's documented limitations [1]:

Recent versions of macOS restrict monitoring of the keyboard for security reasons. For that reason, one of the following must be true:

- The process must run as root.

- Your application must be whitelisted under "Enable access for assistive devices." Note that this might require packaging your application, since otherwise the entire Python installation must be whitelisted.

- On macOS versions after Mojave, you may also need to whitelist your terminal application if running your script from a terminal.

I wonder if they'll index more repositories over time. As it stands, there's no clear way to tell what's indexed versus what's not. A transparent way to see the scope of coverage would be incredibly helpful for users.

John Oliver discusses how so many people have come to take on student loan debt, why it’s so hard to pay off, and what we can do about it [1].

New comment by wizerno in "The Future of TLA+ [pdf]"

wizerno — Wed, 28 Aug 2024 21:30:53 +0000

As someone who's fascinated by formal verification and who's early in their career, what advice do senior folks who have been using TLA+ have?

TLA+ isn't taught in most universities and while I've read about so many interesting applications, I'm yet to convince myself that someone would hire me for knowing it rather than just teaching it to me on the job. Any tips to get started would also be appreciated!

If you're referring to the StackOverflow example from the article, it's different because they follow `/questions/:id/:slug`. Keeping slug at the end makes it a lot easier to delete while keeping it readable.

While the slug helps someone know what they're opening before reading it, most apps have link previews which give you just enough information you need.

As per RFC 3986 [1], reserved characters such as , and / must be URL encoded.

, is encoded as %2C

/ is encoded as %2F
