Realitätsabgleich Ukraine. - Und dort sieht man was man mit Deutschland vor hat, alle Menschen sollen in die Städte um zu knechten und das Landleben soll viel zu unattraktiv werden.
>>[...] Die Weltwirtschaft ist ein Pyramidenschema [...] << - AKA Schneeballsystem. >>Mit steigendem Lebensstandard sinkt das Bevölkerungswachstum. Wenn es der Wirtschaft also gelingt, den Lebensstandard zu erhöhen, untergräbt sie sich selbst.<<
Die Blockpartei zeigt wieder, dass sie nicht für das Volk arbeitet. - Stadt bezahlbaren Wohnraum und ordentliche Infrastruktur im gesamten Bundesgebiet zu schaffen, will man sich noch mehr auf die Verdichtung der Städte konzentrieren. Wir sehen ja in andern Ländern wie gut das funktioniert ... zumindest für die Immobilienhändler.
A monitoring tool is parsing a big file every x minutes to count the amount of a word inside.
If the counted amount is less than a threshold limit, counter measurements are triggered.
This big file is created once per day.
This is working fine if the file is small. Now think about xml files with a size of gigabytes and this files are on a network storage and you have many of them to monitor.
My solution for this problem is to create a caching layer.
The only thing we need to solve is to detect if the big file has changed.
Using sha256sum on big files takes time.
Using md5sum on big files takes time.
There is one thing that is fast and good enough to be unique.
ls -l jobs_with_channels_multiple_location_nodes.xml | awk '{print $5$6$7$8}'
Where to store the cache?
Just use the name of the big file and add a ".cache" to the name.
What should be in the cache file?
Only two lines. First line is the cache key, second line is the cached count value.
And the logic?
#!/bin/bash
####
# Counts amount of <foo> nodes in provided file.
# To speed up things, we create a cache file.
#
# This is just an logic example file. If you are using it on production, good luck!

Result is, that I've created a sql statement with a >>%<< inside. I need to escape it (transform it to >>%%<<) and all is fine.
I had the joy to debug a not working contao system line by line.
Why line by line? Because there was no entry in any logs, even with "log all motherfucker"-php.ini values on.
After parsing the lines, I ended up into this error message.
Fatal error: Cannot use 'String' as class name as it is reserved in ... system/modules/core/library/Contao/String.php on line 28
Well, nice to know the error but where was this triggered?
So another round with joy and I ended up with an extension, of course installed "by hand" which means not possible to update by the contao updater and this lovely line.
$this->import('String');
After I've changed that line to the following line, all the gizmos where working again.
$this->import('StringUtils');
So, what should you do when you where faced with a 500 Apache Status Code after a contao installation moved from an PHP 5.x runtime environment to a PHP 7.x runtime environment?
cd <project root>
grep -ir "import('String');" *
Replace >>import('String');<< with >>import('StringUtil');<< and that is it.
But all would be better if you are not installing extensions by hand.
So, nextcloud version 15.0.x is out already and whenever you are logging into your next cloud with your administrator account, you still get this "you are on the latest version" message.
Further more, you just got a update to version 14.0.x while waiting for version 15.0.x.
To fix this, all you have to do is to switch from the channel "stable" to "beta".
After a page reload, you should see a version 15.0.x available.
Do the upgrade and do not forget to switch back to the stable channel.
