Wikipedia goes 3 columns

Recently I had to read a lot of wikipedia articles. If you have a widescreen monitor - you know how its looks like. Very long lines of text stretching across the whole 1920px wide of browser window. As well as big gaps of free space near contents and infobox tables. I thought that it's possible to somewhat improve readability of wikipedia by using greasemonkey and new html5 columns markup. Done ;)

Script will:
- Display wikipedia article text in 3 columns
- Hide menu and ads
- Move contents table and infoboxes to left pane instead of menu

Installation:
- You'll need a userscript compatible browser
- Then just click this link
- OR use openuserjs.org mirror

Enjoy!

P.S.

D-Link DIR-620 OpenWRT installation

I've use OpenWRT for my D-Link DIR-620 A1 for almost a year now. Good news that OpenWRT community released already compiled beta versions (Latest for now is 12.09-rc1) So now it's no need to compile trunk sources to get firmware for ramips hardware. My custom image is getting old, so I decide to install latest community release.
This article is mostly for myself. Just want to leave some notes in case I'll need to update firmware again. So I'll make it very brief.

Install volume deduplication from Server 2012 to Windows 8

Server 2012  has a great feature - Deduplication. It can be very effective to optimize storage and reduce the amount of disk space consumed—50% to 90% when applied to the right data. Cause Windows 8 has a Hyper-V 3 too, deduplication will be very usefull for VM vhd storage volume. This is my VM folder example:

And this example taken from Windows 8 =) So, it's possible to install deduplication service to Windows 8 with one caveat - it'll have no GUI. Only possible way to manage it - is Powershell.

Asterisk sync with Active Directory

In my case, all users information is stored in AD (yes, we use Exchange GAL). It'll be great if asterisk get this information directly from AD without need in configuration editing.

Let's look what we have now:
AD user have fields 'telephoneNumber' - for internal extension number, 'fax' - for direct inward dialing number (DID) like this:

Reading PDF in landscape mode on Kindle Touch

Current version of firmware for Kindle Touch lacks support of landscape mode. WTF! There is jailbreak already, but no any lanscape hack. What will be very usefull for reading pdf. So, if there is no way to make it directly on Kindle, we will make it for Kindle)
I'm use k2pdfopt like this:
k2pdfopt.exe -col 1 -j 0+ -ls -ui -fc- -odpi 130 -h 711 -w 521 -om 0 -cmax 1 -s- -rt 0 -mb 0.7 %1

Let's look at them in detail:

• -col 1 - means that there is no need to find any columns in text. If you have tables, this will helps to not break them to columns at new pages
• -j 0+ - tries to justification text left
• -ls - rotate page to landscape
• -ui - run UI for making additional tuning before converting
• -fc - don't fit columns to width
• -odpi 130 - slightly zooming of input file
• -h 711-w 521 - width and height of screen zone for displaying pdf. There is table for other readers.
• -om 0 -disable output margin, Kindle Touch already has margin about 10px near pdf displaying zone
• -cmax 1 -s- - disable increasing of contrast and sharpening. This makes fonts looks more like ClearType, with soft edges.
• -rt 0 - disable auto determination of source orientation
• -mb 0.7 - cut bottom margin of source in inches. This is for cutting original footer with page number etc on every source page.
• %1 - name of source pdf

You can save this as .cmd file, and drag'n'drop your pdf files over.
Examples of source:

and 2 pages of zoomed output:

bash

Some bash hotkeys:

Ctrl + A  Go to the beginning of the line you are currently typing on
Ctrl + E  Go to the end of the line you are currently typing on
Ctrl + L  Clears the Screen, similar to the clear command
Ctrl + U  Clears the line before the cursor position. If you are at the end of the line, clears the entire line.
Ctrl + R  Let’s you search through previously used commands
Ctrl + C  Kill whatever you are running
Ctrl + D  Exit the current shell
Ctrl + Z  Puts whatever you are running into a suspended background process. "fg" restores it.
Ctrl + W  Delete the word before the cursor
Ctrl + K  Clear the line after the cursor
Ctrl + T  Swap the last two characters before the cursor
Esc + T  Swap the last two words before the cursor

Some notes about reverse history search. It'll iterative show last command for your search query. For next item press Ctrl-R again. To search forward press Ctrl-S. (On some terminals this bind to freeze, press Ctrl-Q to defreeze) More about history navigation here
