Split Files on embedded Linux Systems

If you run a embedded Linux PC like raspi often some Linux Commands fail without error messages, cause the hardware performance is low tech.

Same i have seen on the split command..

to split a 50GB Photos-Archive File to 4Gb on a USB Drive i found out that:

sudo split -b 4096m -d -u Photos.tgz Photos-Archive_

fix the job..
Cause option -u disable IO-Caching over the 2.0 USB Port to the RAM of the raspi that the Data of the Output Stream is written direct to the Drive.

BIG DATA COMPANYS ABUSE POWER

If have read the latest News about the Big Data Collector and his for FREE shared Browser, you see that the big data Company’s abuses their power to block Websites from their Buisiness.

With the next upcoming Releases they prevent fast access to public News Sites or other Blogs and enforces the Website Owners to ACCEPT the NEW RULES.

You see that most FREE Software IS NOT REALLY FREE Software, cause it’s a Tool to take CONTROL over the normal USERS!

To PREVENT this POLITICS try to use ALTERNATE SOFTWARE like the ICECAT Browser, sometimes it’s more useful to have a CLOSER look at the SOFTWARE you use at you DAILY Office.

Locale Umloud Problems Cron

If you run scripts to handle text output by cronjobs your perhaps get problems with umlouds „ÖÄÜ“ cause they are displayed by „**“.
This is a problem cause cron uses „C“ setting as locale, you can test it by setting it into root crontab:

open crontab from root with:

$su - root
$crontab -

insert
* * * * * locale

This will mail cron’s locale echo to the mailbox of root! Read root’s mail!
After tests remove the locale entry at crontab!

Howto fix for Scripts:

open crontab from root with:

$su - root
$crontab -e

insert (for German):

LANG=de_DE.UTF-8 
LC_ALL=de_DE.UTF-8

for US:
LANG=en_US.UTF-8 
LC_ALL=en_US.UTF-8

Linux: Systemd ignore console-setup settings

If you work on older Laptops and you use a Console only System Setup like on Debian there is a Bug on systemd and the console-setup package since years. After reboot all Font Settings seems gone. But the Settings are not real gone, cause systemd does not pull the settings on boot!

How to fix?

  • edit the crontab of root by

sudo su -
crontab -e

  • insert the /bin/setupcon command on „@reboot“ means on every boot!

@reboot     /bin/setupcon > /dev/null 2>&1 

  • save and exit, reboot now
  • now the PC should echo big Fonts for old eyes „Terminus 20×12 Frambuffermode“
