Re: Forum page update

When I said "slow connection" I did not mean that you had a slow connection at your end.

It's quite likely that the HTML file and the CCS and other files don't get served at the same time, or from the same place, or take the the same route to get to you.

The web is chaotic like that.

Re: Raspberry PI Web Server

I have come to think that it's best not to think in terms of "local LAN" and "internet. That leads one to assuming "local LAN = safe", "public internet = dangerous". That leads one to building firewalls around the local LAN and feeling good about it. Well guess what? Any machine that can reach the n...

Re: Forum page update

That is not a "different page" it is the HTML text of the page you ordered. Rendered by your browser in the most basic way before any style (CSS) and other files have arrived. On a slow connection you may well see that crude rendering for a while. When the CSS and other files arrive the browser re-r...

Re: sched: RT throttling activated

No idea. Despite loading up Pi with work for a long time I have never seen that message. I take "RT" to mean "Real Time" I presume any kind of "throttling" happens because something is getting over loaded. Too much work load, too much process scheduling, too many interrupts firing off.

Re: is JB weld good idea to attach HeatSink to 4b ?

Do note that whatever you use between the chip and the heatsink should be as thin as possible. Even proper heatsink compound is a terrible conductor of heat. But almost anything is better than air. So the idea is only to displace air from the spaces between micro-irregularities of the chip and heats...

Pancho88,

Ah yes, sorry, I forgot. There are so many YAFPL's out there it hard to keep track.

It's great that you only have source code there. That talk of an "Execs" directory strongly suggests otherwise.

Any mention of google drive or such is of course rather off putting.

Hey, what is the problem with name mangling in C++? One almost never has to even look at mangled names in C++. No more so than one ever has to look at the assembler code it produces. On the rare occasions when it's useful to be looking at those things then just demangle them: with "objdump -C" or wh...

I we comparing like for like there.

To be fair to C++ a good half of the standards document is not about the language itself but the standard library.

The amount of libraries that comes with Java as standard is far bigger, I would expect the complete documentation to be much more pages than that.
