redis-cli just can not understand my input · Issue #6146 · antirez/redis

For those running into this issue, have you tried flushing the session store in Redis? Delete all keys that start with session:gitlab from Redis.

A good reference for that is, if you just update the instructions to use '/var/opt/gitlab/redis/redis.socket' and 'redis-cli --scan --pattern "session:gitlab:*"' instead.

Just 'docbook-xsl' is enough on CentOS, I think. There is no 'xsltproc' package. Also, moreutils' Makefile points to the wrong place for the DocBook stylesheets, so you need to

sqlite - Compile Python 3.4 with sqlite3 - Stack Overflow
There is also the option of pre-linking your custom Python build with your own-built sqlite3. (I had the same issue: the custom python was using the system-provided sqlite3, completely ignoring the sqlite3 I built).

Prefix your configure and make commands with:
<code class="language-bash">LD_RUN_PATH=$HOME/opt/lib configure LDFLAGS="-L$HOME/opt/lib" CPPFLAGS="-I$HOME/opt/include" …
LD_RUN_PATH=$HOME/opt/lib make</code>

so that the built python3 by default is linked to your sqlite3. This worked for me.

Additionally, turning on this flag tells MySQL that incoming data should be treated as UTF-8. This will only take effect if used as part of the call to connect(). If you turn the flag on after connecting, you will need to issue the command SET NAMES utf8 to get the same effect.

THEN, you can move that 'lua.pc' into '/wherever/you/stow/lua-5.3.5/lib/pkgconfig' and update the PKG_CONFIG_PATH environment variable.

ExifTool FAQ
By default, ExifTool applies a print conversion (PrintConv) to extracted information to make the output more human-readable. Some conversions involve lookup tables which are documented in the Values column of the tag name documentation. For example, the GPSAltitudeRef tag defines the following conversions:
0 = Above Sea Level
1 = Below Sea Level

For this tag, a value of '0' is printed as 'Above Sea Level', and '1' is printed as 'Below Sea Level'. Reading and writing with ExifTool is symmetrical [with the possible exception of list-type tags -- see FAQ number 17 below], so a value that is printed as 'Above Sea Level' must also be written in that form. (In other words, the inverse print conversion is applied when writing values.) For example, to write GPSAltitudeRef you can type:
<code class="language-bash">exiftool -gpsaltituderef="Above Sea Level" image.jpg</code>

or any unambiguous short form may be used and ExifTool will know what you mean, eg)
<code class="language-bash">exiftool -gpsaltituderef=above image.jpg</code>

Alternatively, the print conversion can be disabled for all tags with the -n option, or for individual tags by suffixing the tag name with a '#' character. In either case the printed value of GPSAltitudeRef will be '0' or '1' when extracting information, and the value is written in the same way. So following two commands have exactly the same effect as above:
<code class="language-bash">exiftool -gpsaltituderef=0 -n image.jpg
exiftool -gpsaltituderef#=0 image.jpg</code>

mysql - Can't connect to localhost using Python's MySQLdb - Stack Overflow |
I've managed to solve this by setting my host to "" rather than "localhost".

Turns out if the socket isn't in the default location (/tmp/mysql.sock), the MySQLdb client doesn't take any special measures (lazy!) to discover where it's ACTUALLY at, according to the /etc/my.cnf.

For example, on CentOS (6?), using the SCL version of MySQL, it's at /var/lib/mysql/mysql.sock.
if your mysql socket is not placed in /tmp/mysql.sock, you can specify it with
<code class="language-python">conn = MySQLdb.connect (unix_socket = 'path_to_your_socket', host = 'localhost', user = 'erin', passwd = 'erin', db = 'sec')</code>

edit: for mamp on macosx the mysql socket path should be something like /Applications/MAMP/tmp/mysql/mysql.sock

To figure out where the heck the socket actually *is*, this might work:
using <code class="language-bash">mysql_config --socket</code> in your shell should do, or /path/to/mysql/bin/mysql_config if you installed it in /opt or something – roman Jan 11 '11 at 20:56

c++ - undefined reference to boost::system::system_category() when compiling - Stack Overflow |
The '-lboost_filesystem' didn't work for me with the MacPorts version of Boost (either 1.59 or 1.65, I dunno), but setting '-DBOOST_SYSTEM_NO_DEPRECATED' did. Oh, and you also need '-lboost_filesystem-mt' (multithreaded?).
Linking with a library that defines the missing symbol (-lboost_system) is the obvious solution, but in the particular case of Boost.System, a misfeature in the original design makes it use boost::system::generic_category() and boost::system::system_category() needlessly. Compiling with the flag -DBOOST_SYSTEM_NO_DEPRECATED disables that code and lets a number of programs compile without requiring -lboost_system (that link is of course still needed if you explicitly use some of the library's features).

Both update-manager and dist-upgrade will remove old packages and install new ones that are in the updates. Just running sudo apt-get upgrade will only install new versions of packages that you already have on your system.

Editline Library (libedit) - Port of NetBSD Command Line Editor Library |
ncurses is required for libedit (which is required when you can't get Ruby 2.5.something to build with readline).

In order to build libedit successfully, you either need to have your ncurses headers in the $PREFIX/include directory, or explicitly give CFLAGS *and* CPPFLAGS a '-I/path/to/your/include/ncurses', because ncurses itself puts its headers in a 'ncurses' subdirectory.

The 'CPPFLAGS' one was surprise to me, but if you don't you get this error message while './configure' runs:
