@JordiGH The directory permissions might make more sense if you think of a directory as holding a list of files. You need read permission to read the list, write permission to modify the list and access permission to access the list of files.
See this website to see if this helps explains directory permissions [ https://www.hackinglinuxexposed.com/articles/20030424.html ].
Nothing on TRV seems standard. The thread, the valve pin height, the travel of the pin; nothing. The thread seems to have settled out now at M30, but it's a surprise they work at all.
A valve 'head' has the temp control, it screws to the actual valve which has a 'pin' which is open (hot) up and closed (cold) down (only thing standard).
I have a thread adapter, that's machined metal with an extension pin - the length of which is wrong for the smart TRV I have. Frigged with a spacer; working?
Hmph, the EUrotronic Spirit Zwave TRV doesn't like the screw converter I've got to make it fit on my office radiator - which is a shame because neither are cheap - I might have to play around with lengthening/shortening the pin.
This converter is basically a machined metal cylinder with the right threads, and then a free floating extension pin down the middle, with circlips that limit it's distances.
An interesting spotting. At a quick glance, you might think it's just a piece of bird dung. But it's actually a spider: a Lesser Bird-dropping Spider (Cyrtarachne bufo).

This explanation of the the CVE in Skia's rasterizer is fascinating: https://googleprojectzero.blogspot.com/2019/02/the-curious-case-of-convexity-confusion.html
Just seen the first daffodils of the year; it must be #spring !
For some reason I'd not noticed #bash lets you & a whole loop - e.g.
while true do whatever done &
makes life pretty easy.
I spent a few years working on Itanium projects at Transitive (an emulation company) - it was a fun (if slow) chip to work on. I've got a disembodied Itanium2 (and it's heatsink) but not a full machine.
@penguin42 not in the way modern x86 does it, from what I've read, though it's got some branch prediction and more explicit support for speculative loads.
I don't quite grok everything in this article from Raymond Chen's Itanium deep-dive yet, I might go back and re-read the earlier entries before trying again ;) https://blogs.msdn.microsoft.com/oldnewthing/20150804-00/?p=91181/
