Set an HTML page as the wallpaper on Linux


I want to set an HTML file with JavaScript as my wallpaper on Linux. I'm running Openbox, how can I set it up so this is my desktop background?



Answer



I would recommend running a lightweight browser in the background, as suggested earlier.


This browser should be perfect, since you only want to use it to set a single page as your background. It uses WebKit, so everything should display just fine, and it's light enough that startup should be instant.


As long as you have gtk, webkit-gtk, python, and the python bindings for webkit-gtk (installed by default on many distros, and available from most package managers), you can save it to your home directory as, say, browser.py and add something like:


python ~/browser.py YOUR_WEBSITE &     #browser.py requires http:// before remote urls

to your ~/.config/openbox/autostart in order to have it start along with openbox.


You could then edit your ~/.config/openbox/rc.xml to include something like this under the section:



  no
  yes
  below
  all


To get keybindings like "W-d" to work, you might want to install wmctrl (also available in most package managers).


This script should take you to your "desktop", regardless of whether or not it's started (See here for original script; also, there may be a slight delay in which your actual desktop is shown before the script focuses your browser, but not nearly enough to be bothersome.):


#!/bin/sh

terminal_wm_class="Browser.py"
terminal_exec="python ~/browser.py YOUR_WEBSITE"

# no terminal started, so start one
if [ -z "`wmctrl -lx | grep Browser.py`" ]; then
    $terminal_exec &
else
    wmctrl -x -a $terminal_wm_class
fi;

You can save it in your home directory as something like showdesktop.sh, then replace the default W-d keybinding in ~/.config/openbox/rc.xml


with



  
  
    ~/showdesktop.sh


Once you're done, you can just A-Tab back to your previous window.


(If you want to preserve your window layout, it's probably easiest to switch to an empty desktop with C-A-Left or W-F4, etc. (see default rc.xml), then back with C-A-Right or W-F1, etc., depending on your keybindings and current desktop.)


If you navigate from your start page for any reason, you can just close the window (A-F4 default) and press W-d to run showdesktop.sh and take you back to your homepage


Any of these can be modified or used without the others, so feel free to use whatever works best for you.

Use Google instead of Bing with Windows 10 search

I want to use Google Chrome and Google search instead of Bing when I search in Windows 10. Google Chrome is launched when I click on web, but it's Bing search. (My default search engine on Google and Edge is http://www.google.com ) I haven't found how to configure that. Someone can help me ? Answer There is no way to change the default in Cortana itself but you can redirect it in Chrome. You said that it opens the results in the Chrome browser but it used Bing search right? There's a Chrome extension now that will redirect Bing to Google, DuckDuckGo, or Yahoo , whichever you prefer. More information on that in the second link.

linux - Using an index to make grep faster?

I find myself grepping the same codebase over and over. While it works great, each command takes about 10 seconds, so I am thinking about ways to make it faster. So can grep use some sort of index? I understand an index probably won't help for complicated regexps, but I use mostly very simple patters. Does an indexer exist for this case? EDIT: I know about ctags and the like, but I would like to do full-text search. Answer what about cscope , does this match your shoes? Allows searching code for: all references to a symbol global definitions functions called by a function functions calling a function text string regular expression pattern a file files including a file

How do I transmit a single hexadecimal value serial data in PuTTY using an Alt code?

I am trying to sent a specific hexadecimal value across a serial COM port using PuTTY. Specifically, I want to send the hex codes 9C, B6, FC, and 8B. I have looked up the Alt codes for these and they are 156, 182, 252, and 139 respectively. However, whenever I input the Alt codes, a preceding hex value of C2 is sent before 9C, B6, and 8B so the values that are sent are C2 9C, C2 B6, and C2 8B. The value for FC is changed to C3 FC. Why are these values being placed before the hex value and why is FC being changed altogether? To me, it seems like there is a problem internally converting the Alt code to hex. Is there a way to directly input hex values without using Alt codes in PuTTY? Answer What you're seeing is just ordinary text character set conversion. As far as PuTTY is concerned, you are typing (and reading) text , not raw binary data, therefore it has to convert the text to bytes in whatever configured character set before sending it over the wire. In other words, when y...
