Increasing the maximum upload file size in WordPress

Locate php.ini. For Debian this file is located in:


Search for the following configuration lines (in nano use CTRL+W for search) and replace the existing configuration values with acceptable values.

max_execution_time = 60
memory_limit = 128M
post_max_size = 64M
upload_max_filesize = 64M
max_input_time = 60
file_uploads = On
safe_mode = Off

Locate .htaccess file in the root of your wordpress directory and add or adjust:

php_value upload_max_filesize 64M
php_value post_max_size 128M
php_value memory_limit 256M
php_value max_execution_time 300
php_value max_input_time 300

When you open the media library in WordPress and try to upload a file it should reflect the maximum configured upload file size:

InfluxDB update from 1.8.6-1 to 1.8.7-1

Upgrading InfluxDB failed. For some reason the update caused permission issues with the start-up script:


When I gave this file permission to execute the InfluxDB service started again:

chmod +x /usr/lib/influxdb/scripts/

Then, the next problem appeared: systemctl didn’t recognise that the service was actually running: it was stuck in the state “activating”. Then I found an article on serverfault that described my problem.

I’m running InfluxDB on Debian so couldn’t apply the suggestion solution, but needed to interpret this a bit. I edited the file:


I changed the type to simple, as indicated in this code sample:

Description=InfluxDB is an open-source, distributed, time series database



Check the disk space consumption of a Linux directory

Today, one of my virtual systems ran out of disk space. To find the root cause I needed to find the directory that was filling up. Using the right parameters, the du command returns a list of directories and their disk space consumption.

du -hc --max-depth=0 /var

For example:

root@DB152:/# du -hc --max-depth 1 /var
704K    /var/tmp
4.0K    /var/mail
23M     /var/log
1.1M    /var/backups
4.0K    /var/local
3.2G    /var/lib
20K     /var/spool
734M    /var/cache
4.0K    /var/opt
3.9G    /var
3.9G    total

Removing files of a certain type recursively:

find . -name "*json.log" -type f -delete

Clearing (system) log files:

truncate /var/log/* --size 0

Reduce disk space consumption in Windows 10

Windows 10 can be quite hungry when it comes to disk space, especially when the system has been used for several years and has been updated several times. In some situations temporary update files are “stuck” in the C:\Windows\WinSXS directory, which at that time can consume up to 17Gb of disk space. Microsoft has published an article describing the process to clean up this directory in more detail. However, this doesn’t always work as described.

I recommend you to do the following:

  1. Download the latest version of System Cleanup, an old but ad-free program that scans the system for temporary files.
  2. Run the Disk Clean-up (as administrator!) and clean-up the system.
  3. Use Dism, the command line deployment tool, the merge existing update images into the current installation using the commands below. This might take several hours to complete. You might need to repeat them once or twice to take effect.
Dism.exe /online /Cleanup-Image /StartComponentCleanup /ResetBase
Dism /Online /Cleanup-Image /RestoreHealth
Running System Cleanup, an old but ad-free tool that scans the system for temporary files.
Starting Disk Clean-up as administrator. Make sure you tick all necessary boxes for clean up.

These steps helps helped me to free up roughly 12Gb of storage space on a small little tables that only had a 32Gb drive. Its users can now enjoy using it again for the occasional e-mail and card game, without worrying about a lack of disk space and, as a result, missing important security updates.
