Screen Casting with Wi-Fi Direct from Ubuntu
Read this summary first.
Read this how-to second.
Unfortunately HP Compaq TC4400 does not support Wi-Fi Direct.
I know this from the directions of the above how-to. I installed "iw" through synaptic and checked for "p2p" under "supported interface modes" in ~$ sudo iw list -- and there was none.

How to extract a unique distinct list from a column in LibreOffice Calc with range filter criteria

Using this method it is possible to filter a range of data with the INDIRECT function.

you will have to change the $A$2:$A$20 range two times to the wished range given by INDIRECT.

=INDEX($A$2:$A$20, MATCH(0, COUNTIF($B$1:B1, $A$2:$A$20), 0))

Let's say you have a third column, C with a header row 1 and data from row 2.
This function will work only if the data in column C is sorted.

You type your filter criteria in cell $E$1.

1. using MATCH to find the first occurrence of the filter criteria:
2. MATCH($E$1,$C$1:$C$20,0)
3. using COUNTIF to fing out how many rows have this criteria:
   COUNTIF($C$1:$C$20,$E$1)
4. the range will start in the row given by MATCH($E$1,$C$1:$C$20,0)
   and end in the row given by (MATCH($E$1,$C$1:$C$20,0)+COUNTIF($C$1:$C$20,$E$1)-1)
5. now add the letter of the data column to the range like "A"&
6. your range starting cell will be INDIRECT("A"&MATCH($E$1,$C$1:$C$20,0))
   your range ending cell will be INDIRECT("A"&(MATCH($E$1,$C$1:$C$20,0)+COUNTIF($C$1:$C$20,$E$1)-1))
7. the string you will paste in place of $A$2:$A$20 will be INDIRECT("A"&MATCH($E$1,$C$1:$C$20,0)):INDIRECT("A"&(MATCH($E$1,$C$1:$C$20,0)+COUNTIF($C$1:$C$20,$E$1)-1))

How to extract a unique distinct list from a column in LibreOffice Calc

Hi all,

to this problem: http://nabble.documentfoundation.org/Generate-Unique-List-from-Values-in-Column-td4077250.html

this is the solution in MS Excel,
http://www.get-digital-help.com/2009/03/30/how-to-extract-a-unique-list-and-the-duplicates-in-excel-from-one-column/

and to do this in LibreOffice the single difference you have to make is to not click and drag, but to ctrl+click and drag down the cell contents!

so, step by step:

you have a header: row 1.
your list starts in row 2 in column A.
your unique list will start in row 2 column B.

you type =INDEX($A$2:$A$20, MATCH(0, COUNTIF($B$1:B1, $A$2:$A$20), 0)) in cell B2 and hit CTRL+SHIFT+ENTER

this should result in you having one of the values of your A2:A20 list in B2.

now press CRTL and click and drag down the bottom-right corner of B2 cell.

if you drag down long enough, #N/A cell contents should show up on the bottom of your unique list.

Mplayer for music

I would like to have something like this:

1.) nautilus script
right click on file/dir to copy full path of file/dir
2.) text file
to paste the full paths of to be played items or dirs
3.) utility to handle the text file as a playlist

Description of the utility:
- uses mplayer to play audio/video files
- reads the first line of the text file, starts to play it, than deletes it so the second line becomes the new first line (alternately it moves the line to another text file's end, so the user can go backward in the playlist)
- user can edit the text file on-the-fly between tracks (edit playlist while playing)
- utility should be fool-proof (in case of wrong input it should pause and wait for user to correct error in playlist)

SD card failing...

I got these kind of errors with my microSD cards when I want to write on them. One is a 32GB SDHC the other is a 2GB SD.

in nautilus

Error creating file system: helper exited with exit code 1: Error calling fsync(2) on /dev/mmcblk0p1: Input/output error

with cp

cp: cannot create regular file `/media/Zene/test.mp3': Input/output error

with rsync

rsync: rename "/media/Zene/.test.mp3.FUG0AR" -> "test.mp3": Input/output error (5)
rsync: mkstemp "/media/Zene/.test.jpg.MMYg55" failed: Read-only file system (30)
sent 149488152 bytes  received 183 bytes  499126.33 bytes/sec
total size is 149469329  speedup is 1.00
rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1060) [sender=3.0.7]

and after this the drive was empty once again :-/

even in windows7, SD card dismounts after copy finished and almost everything disappears from the drive. SD slot did not come up on win7.

regarding the mp3 player I wanted to prep for usage with sd card, the files have to be loaded one after another to keep the order of the songs of the albums.

to copy sequentially use {rsync -v -r source/. for local folder/ dest} for directories.

~$ sudo fsck -v /dev/sdcard
can write out interesting information, but has been no help regarding this problem.

Mplayer music playback with playlist

the command to use:

$ mplayer -playlist playlist.txt 

to make a playlist:

1. go to the directory that contains the files you want to make a playlist of.

2.

$ find . -type f -name "*.mp3" | sort > directory_playlist.txt

3. edit txt file so it has the full path (not necessary)

to do the same with a one-line command (if you do not need to edit the playlist):

$ mplayer -playlist <(find /directory/of/your/music/ -name "*.mp3" -type f | sort)

hit enter for the next track

cit crtl+c to break playback

A couple of useful commands with or within mplayer:
-shuffle : shuffle playlist
-loop : play the playlist repeatedly (can be combined with -loop)

Google Tasks: what it can and cannot do

As you can see on this page, Tasks are accessible from Gmail, from Calendar and from Mobile, through a web browser.

For what I use it for...

Let's begin with the useful parts:

• it is possible to turn an e-mail into a task
• it is possible to drag and drop due tasks in the calendar
• it is possible to make separate lists for separate fields of tasks

Now, there...

• it is not possible to set due date for e-mail tasks with one click.
• for me the best would be if whatever e-mail I turn into a task would turn due for today, because than I can drag and drop it in the calendar.
• it is not possible to archive task items, it is only possible to delete them.
• for this reason my tasks list is hundreds of items long.
• it is not possible to multiple select tasks to move them around in your list or add due date to them
• it is not possible to view different task lists simultaneously in calendar
• therefor I do not use different lists

If you happen to know a solution to the functions I miss, please leave a comment to this post and tell me about it!

DJVU extract images

A useful link:
http://askubuntu.com/questions/46233/converting-djvu-to-pdf

Another useful link: http://unix.stackexchange.com/questions/20592/extract-several-pages-from-a-djvu-file
http://kheyali.blogspot.hu/2011/08/in-order-to-convert-djvu-file-into.html

And another: http://en.wikisource.org/wiki/Help:DjVu_files#DjVu_to_Images


Extract images from DJVU:
DDJVU
The easiest way to do this is probably by extracting to multipage tiff
Than split tiff file with tiffsplit: http://manpages.ubuntu.com/manpages/hardy/man1/tiffsplit.1.html
Than convert to anything useful.
Except that did not work for the file I had...

Okay, so the second way is the script way. Copy the script, paste it to an empty text file. Give it the extension .sh and give it permission to execute as program. Put it in a directory with all the djvu-s you want to extract and run in terminal.

#!/bin/bash
#Ubuntu 10.04 Lucid Lynx

#Put this script file in a directory with all the djvu-s you want to extract and run it in terminal.
#All the DJVU-s in this folder will be extracted to PNM-s.

### Select files to process
#defining the filelist
filelist=(`find -iname '*.djvu' | sort`)
#counting the files in the filelist
element_count=${#filelist[*]}
echo "alltogether $element_count djvu will be processed"

#process only 1 file at a time:
counter=1
echo "processing file:"
for i in "${filelist[@]}"
do
echo -ne "$element_count/$counter"\\r

#Get the number of pages from input file
pagecount=`djvused -e n $i`
#Set a filelist for the pages
 for (( filelist=1; filelist<=$pagecount; filelist+=1 ))
 do
 #Extract with DDJVU
 ddjvu -format=pnm -page=$filelist $i file_$counter.page_$filelist.pnm
 #Or use DjvuPs to extract PS from DJVU the same way:
 #djvups -page=$filelist $i file_$counter.page_$filelist.ps
 done
let "counter = $counter + 1"
done

echo DONE.

Creating searchable PDFs on Ubuntu 2nd try

Need be:

• image layer over text layer
• good character encoding for Hungarian ű and ő chars
• good placement of words and lines
• fair enough good recognition
• handling more column layout

1st try was Tesseract output hocr embedded with hocr2pdf in a pnm file.

• image layer over text layer - YES
• good character encoding for Hungarian ű and ő chars - NO
• good placement of words and lines - NO
• fair enough good recognition - YES
• handling more column layout - NO

the strangest is, that hOCR editor does not handle well the tesseract output hocr. actually it does not handle it at all, showing html tags and everything where the editable text shoud be...

2nd try is: OCRopus 

I had no success installing and using orcopus.

• "recognize" does not handle languages, and/or I could not find a Hungarian data file for it.
  it works like: ocroscript recognize input.pnm > output.html
• rec-tess-complete should recognize through tesseract, and import language files with the --tesslanguage=hun option, but instead I got this error:
  Unable to load unicharset file /usr/share/tesseract-ocr/tessdata/hun.unicharset
• so I unpacked the hun.traineddata like this:
  combine_tessdata -u hun.traineddata hun.
• and put the files to /usr/share/tesseract-ocr/tessdata/
• however I got this error:
  Error: Illegal malloc request size!
  Fatal error: No error trap defined!
  Signal_termination_handler called with signal 2001
• than I tried with --tesslanguage=eng and it gave me:
  ocroscript: /usr/share/ocropus/scripts//rec-tess-complete.lua:52: attempt to call global 'hardcoded_version_string' (a nil value)
• so I searched and found a patch, and installed it like this:
  patch /usr/share/ocropus/scripts/rec-tess-complete.lua rec-tess-complete3_r1308.patch
• and now it gives me (with "eng")
  ocroscript: /usr/share/ocropus/scripts//rec-tess-complete.lua:61: Leptonica is disabled, please compile with it or don't use it!

I already have the newest tesseract on board, but I failed to manage a newest ocropus installation. it had too many unknown aspects with python and all...

results with ocropus 0.3.1-2 recognize and merged with hocr2pdf:

• image layer over text layer - YES
• good character encoding for Hungarian ű and ő chars - NO
• good placement of words and lines - NO (makes large characters, I cannot even tell which line it should be)
• fair enough good recognition - NO (because of english training data)
• handling more column layout - DON'T KNOW (text was too big, it was impossible to tell)

maybe the big text was because of the dpi of the image... I should check on this to at least be able to qualify the layout option... nope, it did not help... at all.

...to be continued with:

3rd try is: Cuneiform

4th try: Adobe Acrobat XI on Windows

Creating searchable PDFs on Ubuntu 1st try

Process is the following:

1. have a good resolution image in leptonica allowed format to use with tesseract: JPEG, PNG, TIFF, BMP, PNM ,GIF and WEBP.
2. produce hocr output like
   tesseract image.pbm textfile -l hun hocr
3. merge image and hocr to searchable pdf in hocr2pdf: image layer on top of text layer like
   hocr2pdf -i input.pbm -o output.pdf < textfile.html

First impressions:

• character encoding after hocr2pdf is off
  setting character encoding in html file header to ISO-8859-2 or Windows-1250 does not help.
  "ő" turns "Q" and "ű" turns "q" :-(
• 2 columns was not recognized automatically in tesseract
  psm option does not solve this
  this is probably impossible in the current version.
  have to try out another way to produce hocr with an ocr software that handles layout.
• font sizes are chaotic
  I think this probably depends on the bbox size and therefor on the ocr software.
• output file size is 159kb from a 818kb pbm, which is way too big.
  this cannot be helped if the pdf is not generated with my own methods...
  

Anyhow, this looks like a disaster :-( character encoding has to work.

Istalling Tesseract

Thanks to THIS post I was able to install tesseract 3 on 10.04 Ubuntu. This is how:

Install Tesseract
Get the required packages available in the repositories:

sudo apt-get install libpng12-dev
sudo apt-get install libjpeg62-dev
sudo apt-get install libtiff4-dev
("sudo apt-get install zlibg-dev" is suggested in the Tesseract readme but isn't available. I found I didn't need this.)

I picked this up from a comment made, you need to be able to compile and make the software. Ubuntu needs some packages to help do this. For many of you these may already be present and installed but it doesn't hurt..

sudo apt-get install gcc
sudo apt-get install g++
sudo apt-get install automake


Download this program which can't be gained with apt-get:
http://www.leptonica.org/download.html version 1.70
unpack, navigate to the folder in terminal, and run:

./configure
make
sudo make install
sudo ldconfig


Now we can actually get and install Tesseract!

download tesseract: https://code.google.com/p/tesseract-ocr/downloads/list version 3.02.02
unpack, navigate to the folder in terminal, and run:

./configure
make
sudo make install
sudo ldconfig   (<-- important="" is="" p="" this="" very="">

Now for whatever reason the training data isn't installed with this.

download whatever language you need and unzip to /usr/local/share/tessdata folder (requires root permissions)
also download osd traineddata from for example here

try with:
sudo nautilus

OCR Hungarian

After six long years I gathered my courage to face the task of OCR-ing texts again.

Goals:

1.) searchable PDF and/or DJVU from image PDF or DJVU.
one guide for PDFs uses cuneiform to ocr, and hocr2pdf to emberd text in pdf.
another option is pdfsandwich

2.) formatted text file preferably HTML from image.

First impressions:
This program should be able to convert .html/.htm and .epub files...
it converts them to .mobi to a filesize at least double the original (depending on images and compression)
Uploaded to Kindle, all the files seem to work fine. Text formatting is kept in some way - not perfect, but readable. Kindle shows Title and author for the epub, and title set for the html (not filename!)

Seems okay, but I do not have a real chance to generate a beautiful book this way easily... maybe converting from epub might be a chance to keep the book beautiful...

...or should really read the  publishing guidelines to learn the proper formatting.
