It's the same on Wayland. The client (usually part of a toolkit like Gtk/Qt) needs to subscribe to notifications [0] from the server so it can decide the raster size of the surface…

Sir say "tray bean". Mercy.

Indeed, my understanding (which is backed up by your link) is that the hieroglyphs aren't just pictograms that try to draw the meaning but they tend to have particular pronunciatio…

> Exceptions in transactional logic are often used to represent a "rollback persistent store changes made thus far" scenario. Handling can be added to change the transaction to be …

You want to at least check that the exception was raised in the absence of read anomalies. The check for read anomalies in OCC happens during the commit phase. Setting a transactio…

I wasn't thinking of JDBC SQL transactions specifically, but sure, different APIs can denote retriable transaction failures differently. Instead of: if (!tx.commit()) { continue; }…

> A transaction failing is the opposite of an unexpected event. That's why it's denoted by a non-exceptional return value from `tx.commit()` in my sample code. When I've talked abo…

A result of an inconsistent transaction should be discarded whether it's a return value or a thrown exception. If it runs out of tries another error should be thrown. This should o…

Sounds like the right intent to me. To pinpoint your existing quote from the documentation: > The finally block always executes when the try block exits. This ensures that the fina…

The point about inducing segmentation faults is interesting and sounds like it could work to implement the `hint_read` mechanism. I guess it would mostly be a question of how perfo…

I think the model I described is more precise than madvise. I think madvise would usually be called on large sequences of pages, which is why it has `MADV_RANDOM`, `MADV_SEQUENTIAL…

Just to clarify, I think the parent posts are talking about non-failing page faults, ie where the kernel just needs to update the mapping in the MMU after finding the existing page…

But no one has demonstrated an actual operation that requires valid UTF-8. The reasoning is always circular: "I require valid UTF-8 because someone else requires valid UTF-8". Even…

They have effectively done this (since the linked issue was raised), by just converting Windows filenames to WTF-8. I think this is sensible, because the fact that Windows still us…

Ah, mentioning Windows filenames would have been useful. I guess the issue isn't so much about whether strings are well-formed, but about whether the conversion (eg, from UTF-16 to…

Can you give an example of how Go's approach causes people to lose data? This was alluded to in the blog post but they didn't explain anything. It seems like there's some confusion…
