Debian is an acronym, which stands for Debra and Ian, the first name of his then girlfriend Debra and the first name of Ian Murdock, the creator of the Debian project. Ian Murdock passed away at the end of 2015. From the very start, Debian has been a romantic, idealist and living manifestation of the spirit of free software and testimony to the championing of the cause of linux operating system.

Warning: OpenGL appears to be installed incorrectly. Fix: rename the file found at $MATLAB_ROOT$/sys/os/glnxa64/libstdc++.so.6 to libstdc++.so.6.old, restart MATLAB, this forces MATLAB to use the OS library. Also, use LIBGL_DRI3_DISABLE=1 matlab to start MATLAB if R2016b is used. The value of the environment variable LIBGL_DRI3_DISABLE does not matter.

There is a wifi whitelist check in X40 bios and the error code is 1802. There are multiple ways to remove the whitelist check. The way mentioned here is to flip the CMOS whitelist check bit. See

1. The set-up generally follows the quickstart section on page https://www.emacswiki.org/emacs/GnusGmail. But I have my own gnus-settings.el saved in a separate folder as practised by Jess Hamrick. Do use .authinfo.gpg because by default *.gpg will be encrypted by GnuPG. The first time we start gnus within emacs, we will be asked to key in a password; 2. Start gnus by M-x gnus, if there is no new email, we will see blank screen in *Group* buffer (Group is for news reading, hence the name Gnus). Press L (list all groups), we will see all available folders (to which emails are copied according to labels we created in gmail web version). If we have helm-mode enabled, we can search all available key strokes for gnus actions and their descriptions, for example the L above; 3. I disabled Gmail Tabs so all emails come into INBOX folder (all incoming emails are with inbox labels). We can assign new label to an incoming email with B c (copy to, so we can have the email labelled with new tag while it is still in INBOX folder) and remove a label by going to the group/folder under which the email has been stored (once an email has been assigned a label, it will be stored in a separate folder/group), further press B DEL to remove an email from the group, hence removing an label; 4. Fetch new email, press / N when in Summary buffer (meaning you are reading emails) or g when in Group buffer. Mark emails as read, press d; to copy a link in Gnus, press u; (this will copy the url to kill-ring.) 5. Remove auto save list of gnus reading in case we have messed up with gnus, delete ~/.newsrc and ~/.newsrc.eld
1. One of the GnuPG ports on windows is gpg4win. For use within emacs, install gpg4win with GnuPG component only is enough. But there is one line difference in gnus-settings.el (my gnus setting file for emacs), we have to explicitly point to the gpg.exe by (setq epg-gpg-program "/path/to/gpg.exe") Simply include (setq epg-gpg-program "gpg") is not working, even gpg4win has set correct environment variable PATH. 2. Emacs win32 needs some extra library files (though emacs may work for general editing without them), specifically, gnutls, libxml2, and zlib. We need to grab them from ezwinports. Preserve the original file system structures as in the archives and unpack them to disk. (preferably within the same directory where emacs folder resides.) In order for emacs to see them, either include those binaries in the system PATH or in general-settings.el (my general setting file for emacs), add a few more lines for PATH, (setenv "PATH" (concat (getenv "PATH") ";" "C:/Program Files/GNU/GnuPG/pub" ";" "C:/path/to/gnutls/bin" ";" "C:/path/to/libxml2/bin" ";" "C:/path/to/zlib/bin" ";")) 3. Change one line in gnus-settings.el for gmail, ;(nnimap-server-port "imaps") ; *nix only (nnimap-server-port 993) ; windows only 4. w3m is only available with Cygwin but WinXP is too old to install one, so I disabled html rendering with w3m within gnus.
;; for printing (setq lpr-command "") ; nil value, sent print to local printer (setq printer-name "DOT4_001") ; port, WinXP on X41 with HP LaserJet 600 M601 ;; printing with ghostscript (setenv "GS_LIB" "C:/Program Files/gs/gs9.05/lib;") (setq ps-printer-name t) (setq ps-lpr-command "C:/Program Files/gs/gs9.05/bin/gswin32c.exe") (setq ps-lpr-switches '("-q" "-dNOPAUSE" "-dBATCH" "-sDEVICE=mswinpr2")) Print with command M-x ps-print-buffer-* will evoke default print dialogue. However, C-u M-x ps-print-buffer-* will prompt a save as dialogue.
A. First we need to delete the old partitions that remain on the USB key. Open a terminal and type sudo su Type fdisk -l and note your USB drive letter. Type fdisk /dev/sdx (replacing x with your drive letter) Type d to proceed to delete a partition Type 1 to select the 1st partition and press enter Type d to proceed to delete another partition (fdisk should automatically select the second partition) B. Next we need to create the new partition. Type n to make a new partition Type p to make this partition primary and press enter Type 1 to make this the first partition and then press enter Press enter to accept the default first cylinder Press enter again to accept the default last cylinder Type w to write the new partition information to the USB key Type umount /dev/sdx1 (replacing x with your drive letter) C. The last step is to create the fat filesystem. (optional) Type mkfs.vfat -F 32 /dev/sdx1 (replacing x with your USB key drive letter)
Install fonts-symbola from debian testing repo, then add the following line to gnus-settings.el (set-fontset-font t 'unicode "Symbola" nil 'prepend)
