MySQL encoding error: Warning (Code 1366): Incorrect string value: '\xE9, a <...' for column 'body' at row 3

Submitted by Druss on Sun, 2013-06-02 13:10

While performing a CSV import recently, I ran into the following error messages:

Warning (Code 1366): Incorrect string value: '\xE9, a <...' for column 'body' at row 3
Warning (Code 1366): Incorrect string value: '\xE6. He ...' for column 'body' at row 24
Warning (Code 1366): Incorrect string value: '\xE9, and...' for column 'body' at row 26

The first message was triggered due to the accented é in the word, protegé, in the input. The rest of the field was not imported. The others were similarly triggered.

Changing a file's encoding using Vim

Submitted by Druss on Sun, 2013-06-02 13:07

During imports and stuff, it's imperative that all steps utilise the same encoding/character set. If a text file is not using the preferred encoding, we can use Vim to change it during its save action as follows:

:set fileencoding=utf8
:w

or if you want to save it to a different file and leave the current file unchanged:

:w ++enc=utf-8 newfile.txt

Upgrading KTorrent in Kubuntu Precise

Submitted by Druss on Tue, 2013-05-14 12:24

KTorrent on the LTS release of Kubuntu—Precise Pangolin aka 12.04—is perfectly fine except for the fact that it comes only with version 4.1. Unfortunately, this package is missing a few features that I was looking for, especially the option to add magnet links via its web interface.

Upgrading from 4.1 to 4.3 (the latest version at the time of writing) is pretty straightforward if one is happy to accept PPA sources.

PDOException: SQLSTATE[HY000]: General error: 144 Table 'cache_menu' is marked as crashed and last (automatic?) repair failed: DELETE FROM {cache_menu};

While trying to edit a menu on a Drupal site, I found that none of my changes were being saved. Looking at the logs led me to the following error message:

PDOException: SQLSTATE[HY000]: General error: 144 Table 'cache_menu' is marked as crashed and last (automatic?) repair failed: DELETE FROM {cache_menu};

Simply restarting MySQL did not fix things and it looked like I had to get my hands a li'l dirty.

dpkg cannot install as there's no space left on the device even though there is

Submitted by Druss on Thu, 2012-11-22 23:46

I ran into this issue a couple of days ago and cannot recall the exact error message. However, the problem was effectively that aptitude could not install the new kernel update because my partition had apparently run out of space. An interrupted update to Klipper is one thing and the Linux kernel a whole 'nother kettle of fishies. Thinking that I simply needed to free up some space on my partition, I checked the current status via df.

Scrolling within Screen's buffer

Submitted by Druss on Fri, 2012-10-19 21:05

Since I keep forgetting this shortcut, here it is for posterity. Activating GNU Screen's scrollback feature can be done by pressing CTRL + a + [. This is especially handy when you are using Screen from within PuTTY.

While a number of sites provide additional Vim-esque shortcuts to navigate within the buffer, I've been able to get by fine with just the navigational arrow keys on my keyboard.
