$ cat /usr/share/doc/keyboard-configuration/README.Debian After modifying /etc/default/keyboard, you can apply the changes to the Linux console by running setupcon. If X is configured to use that file too, then the changes will become visible to X only if udevadm trigger --subsystem-match=input --action=change is called, or the system is rebooted.

Eine Zwangskühlung über zwei Zusatzlüfter verfügt meine Fräse sowieso schon, da es bei der Orginalmaschine schon von Haus auf ein Hitzestau so das ich da schon etwas nachgeholfen habe.
Steuerplatine für MF-70 Proxxon Fräse
Wie kann man als Hersteller auf diese Waise Kühlöffnungen ungeschützt anbringen, ohne sie gegen das eindringen von Leitfähigen Spänen und Stäuben zu sichern. Ein paar “gewebeähnliche” Matten von innen über die Kühlöffnungen geklebt sollten da schon schlimmeres verhindern.
Andererseits kann ich mir kaum vorstellen,daß diese Dinger für 100% Einschaltdauer geeignet sind.Wenn ich also da die Schrittmotoren drannbaue und irgendein Programm fräsen will,kann es sein das die nach ner Stunde abraucht.
Direkt danach habe ich zwei DS18S20 Temperatursensoren eingebaut, der eine misst die Temperatur des Motors in der Nähe der Bürsten, der andere sitzt auf dem Leistungshalbleiter der „Steuerung“ für die Drehzahl. Danach habe ich die obere Abdeckung kreisförmig ausgeschnitten und einen 5V Lüfter daraufgesetzt, der 13m^3 Luft in der Stunde durch die seitlichen Lüftungsschlitze am Motor vorbei saugt. Jetzt habe ich sehr stabile 31°C am Motorgehäuse und gequalmt hat es bis jetzt auch nicht wieder.

Don’t use absolute pointer
POSIX / System v Shared Memory vs Threads Shared Memory
In the table I mention the virtual memory mapping issues, what is all that about? It’s about being able to store pointers on the shared memory and whenever that make sense. As I point out the memory can be mapped at different virtual addresses in different processes which means that you can’t use absolute pointer. I think this is better understood with a picture:
 |
In the picture process 1 has stored the 0x70000100 address in the shared memory, that points to somewhere in the shared memory for process 1 but when process 2 reads that address it points to a completely different data in that process that it’s outside the shared memory. That is because the shared memory was mapped at 0x7000000 on process 1 but on 0xFF000000 on process 2.
This means that when using POSIX shared memory you will have to refrain from storing pointers and need to store offsets or indexes instead (ptrdiff_t, etc). That, in turns, means that you have to engineer your data structures for shared memory.

These are the possible reasons that routers are not able to sync with the public time servers: High offset and more between the server and the router
So I installed NTP and hoped that it would magically fix up the issue, but it turns out that NTP by itself is absolutely unhelpful not only in cases of big offset, but also in cases of big drift – it will fix your clock when it is slightly inaccurate, but not when it is inaccurate a lot.
