Dvorak resources

-

Since about 2011 I've started using dvorak as my main keyboard layout and like the efficiency compared to QWERTY.

Notes

-

Note to self (2015-10-30)

-

Note to self: x-keyboard-config on arch linux overwrites the - file where the dvorak russian keymap is stored and by that the - xserver fails to set the keymap, returning to default qwerty. - This can be solved by loading the keymap from a custom - location? Or maybe to pin the file so that the package manager - doesn't overwrite it?

- -

Dosbox

-

Dvorak is also usable in dosbox via a custom mapper file that your can find here
- You can enable the layout by saving this in your settings directory and 

mapperfile=dvorak-0.74.map
to your sdl section of your dosbox config.

- -

Update (2020-06-11)

-

Dvorak is now built in as a keymap in dosbox. - You can enable the layout by running 

KEYB dv103
in a dosbox - prompt or setting the following in your dosbox config file. -

- 
-[dos]
-keyboardlayout=dv103
-
- -

Dvorak in dos

-

To use dvorak in dos download this file containing dvorak.com
- Transfer it to your C:\DOS folder for example and add this to your AUTOEXEC.bat:

- 
C:\DOS\DVORAK.COM
-

When your computer boots the program will say DVORAK is loaded and you're good to go

- -

The MS-DOS supplemental disk also contains a dvorak keyboard layout. Install and put this in your AUTOEXEC.bat:

- 
KEYB DV,,C:\DOS\DVORAK.SYS
- -

Russian (2014-10-07

-

When learning russian I had to type some stuff in russian, as I found - out that there was a phonetic keyboard I was excited but it didn't work on - dvorak layout. So some guy named Oleg made a phonetic russian keyboard - layout in dvorak and you can download it - here. When you want to use it you - have to append the information from the file to - 

/usr/share/X11//xkb/symbols/ru
- When you want to load it you can - type - 
setxkbmap -layout ru -variant phonetic_dvorak
-

- -

Update (2015-04-16)

-

Since having to setup the keyboard after login can be useful if you - don't have the rights to edit system configuration files on your system(eg. - work) but it's not a durable solution for your own system. If you want to - make these things semipermanent you can use the handy program called - - localectl - which writes an xorg.conf.d/ file. In my specific case these are the - commands to set the keymap for the console and for within X. For the - console I only use normal dvorak whereas in X I want to be able to - switch(with menu key) and use the right alt as compose key. - 

-# localectl set-x11-keymap --no-convert dvorak,ru pc104 ,phonetic_dvorak compose:ralt,grp:menu_toggle
-# localectl set-keymap --no-convert dvorak

Introduction

-

- ſ-homografen zijn homografen in de reguliere spelling maar bij het correct gebruik van de ſ niet meer. - In vroegere tijden schreef men de kleine letter s als ſ, behalve als het de laatste letter van het woord, of samengesteld woord, was. - De bekendste ſ-homograaf is plaatstaal, dat geïnterpreteerd kan worden als plaats-taal of plaat-staal, maar plaatstaal en plaatſtaal zijn prima te onderscheiden. -

Wifi without network manager

-

- With this setup, wpa_supplicant automatically changes network when needed. - Moreover, the network can be changed in userspace and new networks can be added. - All withouth the bloat of NetworkManager and ModemManager. -

- - -
- -

Requirements

- - -

wpa_supplicant

-

- /etc/network/interfaces needs for direct use with a wpa_supplicant daemon. - This is done by setting the wireless network as follows. -

- - 
-allow-hotplug wlp2s0
-iface wlp2s0 inet manual
-	wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
-
- -

- This basically means that a wpa_supplicant will be watching the networks specified in the config and switch when in range. - Note that the iface is set to manual and not dhcp. - This means that below those lines you can configure your networks from the config manually. - So say that you have a network in the wpa_supplicant.conf with id_str="work"" that needs to be configured with dhcp, you add the following lines: -

- - 
-iface work inet dhcp
-
- -

- Setting id_strs for all networks is tedious so to create a default setting you can use the default network name to for example set all wifi networks to dhcp. -

- - 
-iface default inet dhcp
-
- -

wpa_supplicant.conf

-

- The config file for wpa_supplicant should at least contain the following lines. - The interface line defines the control socket and states that all users in the netdev group may control wpa_supplicant. - The update_config line states that the config file may be updated, thus having persistent changes. - Users you allow changing the config therefore have to be added to netdev. -

- - 
-interface=DIR=/run/wpa_supplicant GROUP=netdev
-update_config=1
-
- -

- Followed are all the network configurations. - For these configuration consult the manpage for wpa_supplicant. - E.g. for WPA2 networks you can use the wpa_passphrase tool. - For eduroam, don't handcraft configs either, use the configuration assistant. - This tool will generate a wpa_supplicant.conf if it fails to talk to networkmanager. -

- -

wpa_gui

-

- Editing the config file is tedious and error prone. - Moreover, it requires a restart of wpa_supplicant to reinistate the config. - Luckily there are two tools that allow you to do this in-place using either the command line (wpa_cli is not discussed here) and via a GUI(wpa_gui). - If your user is a member of the netdev group you can just start it up. - Note that it resides by default in /usr/sbin. - wpa_gui is a graphical frontend where you can add, remove, diagnose and change wireless networks with almost as much functionality as wpa_cli. -

- -

Eduroam

-

- Eduroam gives a nice configuration assistant tools nowadays that will generate a wpa_supplicant.conf entry for you. - Previously you could hash your password using md4 but I haven't tested whether this still works. -

- -

update: cat broken

-

- The tool worked before™ but not anymore on my debian testing version. - Therefore I've pasted my config here for later reference. - You get the ca_cert from the assistant tool. - I might upload that here as well. -

- 
-network={
-	ssid="eduroam"
-	proto=RSN
-	key_mgmt=WPA-EAP
-	pairwise=CCMP
-	auth_alg=OPEN
-	eap=PEAP
-	identity="YOURUSERNAME@ru.nl"
-	anonymous_identity="anonymous@ru.nl"
-	password="YOURPASSWORD"
-#	ca_cert="/home/frobnicator/.cat_installer/ca.pem"
-	domain_suffix_match="authenticatie.ru.nl"
-	phase2="auth=MSCHAPV2"
-}
-
- -

openssl update (not needed anymore)

-

- The new version of openssl disables everything lower than TLSv1.2. - If you see errors in /var/log/syslog about TLS you have to allow lower version TLS versions by changing the last two lines in /etc/ssl/openssl.cnf to: -

- 
-MinProtocol = TLSv1.0
-CipherString = DEFAULT@SECLEVEL=1
-
- -

Interaction with wired interfaces

-

- When you have an ethernet jack as well in your laptop you might be tempted to put this in your /etc/network/interfaces as well -

- 
-auto enp0s31f6
-iface enp0s31f6 inet dhcp
-
-

- However, this results in your machine eagerly waiting for a connection at boot because a connected ethernet jack means a connected card, and the card is always connected in a laptop. - ifupdown-extra contains scripts to fix this. - Just link /etc/network/if-up.d/00check-network-cable to /etc/network/if-pre-up.d/00check-network-cable and be good to go. - If your system has predictable network names you might need to apply this patch first -

+ +## `wpa_gui` +Editing the config file is tedious and error prone. +Moreover, it requires a restart of `wpa_supplicant` to reinistate the config. +Luckily there are two tools that allow you to do this in-place using either the command line (`wpa_cli` is not discussed here) and via a GUI(`wpa_gui`). +If your user is a member of the `netdev` group you can just start it up. +Note that it resides by default in `/usr/sbin`. +`wpa_gui` is a graphical frontend where you can add, remove, diagnose and change wireless networks with _almost_ as much functionality as `wpa_cli`. + +## Eduroam +Eduroam gives a nice configuration assistant tools nowadays that will generate a `wpa_supplicant.conf` entry for you. +Previously you could hash your password using md4 but I haven't tested whether this still works. + +### update: cat broken +The tool worked before™ but not anymore on my debian testing version. +Therefore I've pasted my config here for later reference. +You get the `ca_cert` from the assistant tool. +I might upload that here as well. + +``` +network={ + ssid="eduroam" + proto=RSN + key_mgmt=WPA-EAP + pairwise=CCMP + auth_alg=OPEN + eap=PEAP + identity="YOURUSERNAME@ru.nl" + anonymous_identity="anonymous@ru.nl" + password="YOURPASSWORD" +# ca_cert="/home/frobnicator/.cat_installer/ca.pem" + domain_suffix_match="authenticatie.ru.nl" + phase2="auth=MSCHAPV2" +} +``` + +### openssl update (not needed anymore) +The new version of openssl disables everything lower than TLSv1.2. +If you see errors in `/var/log/syslog` about `TLS` you have to allow lower version TLS versions by changing the last two lines in `/etc/ssl/openssl.cnf` to: + +``` +MinProtocol = TLSv1.0 +CipherString = DEFAULT@SECLEVEL=1 +``` + +## Interaction with wired interfaces +When you have an ethernet jack as well in your laptop you might be tempted to put this in your `/etc/network/interfaces` as well + +``` +auto enp0s31f6 +iface enp0s31f6 inet dhcp +``` + +However, this results in your machine eagerly waiting for a connection at boot because a _connected_ ethernet jack means a connected card, and the card is always connected in a laptop. +`ifupdown-extra` contains scripts to fix this. +Just link `/etc/network/if-up.d/00check-network-cable` to `/etc/network/if-pre-up.d/00check-network-cable` and be good to go. +If your system has _predictable_ network names you might need to apply [this](https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=970359) patch first.
