Sometimes, Photoshop can exhibit unexpected behavior.
One of the solutions is to try to reset the Photoshop Preferences. There are various ways to do it, as outlined here. One way is to hold Alt, Ctrl and Shift keys while the application starts up. You will be asked if you want to delete the Adobe Photoshop Settings File, to which you should answer “Yes” if you are sure you wishlike to have it deleted.
You should also take note, that this means resetting all your settings and preferences to “factory defaults”.
Save For Web
If the problems are only present in the “Save For Web” dialog try holding Ctrl+Alt while selecting Save for Web from File menu. You should be then shown a dialog enabling you to clear the Save For Web preferences. This may not work in all versions of Photoshop, as described here.
TL;DR: This script will help you rename the Gantry 5 Hydrogen theme as a starting point for further customizations.
Recently, I’ve been trying out the Gantry 5 – a theme framework for WordPress. One way to get started with theme development using Gantry 5 is to take the default theme, called Hydrogen, rename it and customize it to one’s needs.
The whole renaming process is described here. It takes few steps, which involve unzipping the theme, changing names of files and directories and doing a find and replace for the word “hydrogen” written in few combinations of uppercase and lowercase letters.
I thought that the whole process could be easily automated with a simple Python script that would repack the theme on the fly while doing all the necessary string substitutions in file contents as well as in the paths.
The script is available here on Github. I hope that it will be useful for people willing to develop themes using Gantry 5 framework.
I’ve created a repository of various scripts I find useful in more or less everyday situations. I have called it ktk, which stands for “kmbt’s toolkit”. It is available at github and currently contains test version of a script called nbsp_pl which I am going to describe in the next post.
I have a Debian-based system with a SATA controller running in AHCI mode. I sometimes need to plug and unplug a disk from an internal SATA bay. The bay is nothing fancy – you just slide a disk cradle into it and the SATA and power sockets make contact.
Wyzard on Unix & Linux Stack Exchange
has a good advice on how to do a proper hot unplug. The following is based on
First you need to unmount the partitions. Then, deactivate any LVM groups with vgchange -an – I don’t use LVM, so I haven’t tried that. Finally, it is a very good idea to unregister device from the kernel and spin it down by
echo 1 > /sys/block/(device name)/device/delete
Then I can hear the disk spin down, wait for it to stop completely and just pull it out. When I put in back in, it registers properly. Please note, that I am using AHCI mode in the controller.
Let’s assume you are running a Debian-based system and have a hard drive at /dev/sdc with a partition /dev/sdc1
mounted. To safely remove the hard drive, first you need to unmount all its
partitions. In this case you may do:
udisks --umount /dev/sdc1
and then spin the disk down with:
udisks --detach /dev/sdc
You should the notice (usually, hear) the disk spin down.
Please note, that we are referring here to the device sdc not its partition sdc1.
