I keep migrating my Skype logs from installation to installation and they are getting pretty large. As they are binary files there is no easy way to split them properly. However I’ve found this tool which parses the logs and outputs the entries. The output however it’s not that usable. For this reason I’ve wrote a python script which organizes the output from the previous tool and generates files in the form: logs/skype-name/date....

To create timelapse videos as the one in the previous post or this one here are some simple steps: 1. connect the camera (Canon 450d in my case) to the computer and turn it on 2. unmount it if it’s mounted automaticaly 3. run the following script (timelapse.sh) to capture images to the computer: <pre lang="bash">#!/bin/bash for i in $(seq 900); do no=$(printf "%04d" $i) gphoto2 --capture-image-and-download --filename="timelapse-$no.jpg" sleep 15s; done You can adjust the number of images or the sleep interval....

I have learned a lot about hibernate cache at the time I wrote the previous article on this subject and this brings also an interesting detail. You are using the query and second level cache. Here is an interesting sequence: 1. You execute a query which returns items of entity A. First time it takes some time. 2. You execute the query again, it takes much less time, you are very happy :)...

Assuming you have the following Oracle table: <pre lang="sql">create table icon(id number(19), icon blob); these are 2 methods I found for inserting the value of a file in the icon.icon column. Method 1 This is the most commonly found method: <pre lang="sql">CREATE OR REPLACE PROCEDURE load_icon (imagefile VARCHAR2) IS src_file BFILE; dst_file BLOB; icon_id NUMBER(19,0); BEGIN src_file := bfilename('TEMP', imagefile); -- insert a NULL record to lock INSERT INTO icon (ID, ICON) VALUES (icon_sequence....

After the Adobe Flex incident I spent a lot of time searching for a real RIA experience library and I found none. The truth is that I could not find any library which allows for the same ease of development, rich interface, multi-platform stability and advanced OOP language. Being fueled by marketing and buzz is not enough to have something solid to develop any kind of real RIA with ease....

TORT, torturi, s. n. Prăjitură (de obicei de formă cilindrică) făcută din mai multe straturi de aluat, având între ele straturi de cremă, de dulceață etc., acoperită cu o glazură sau cremă ornamentală etc. (sursa: dex). Din pacate nu stiu nici o sursa unde pot sa gasesc o felie de tort care sa respecte definitia de mai sus. Majoritatea “torturilor” din cofetarii consta intr-o matrita de plastic in care s-a turnat o crema groasa si sunt acoperite cu un strat de alta culoare....

I ended up with this recipe after searching for a nice holiday gift for my friends and the result was well received ;) Actually I did some tests and I migrated from cinnamon rolls to cinnamon, raisins rolls and finally to poppy seeds rolls cookies. Poppy rolls The dough ingredients 2.5 cups flour 1 egg (there are a lot of recipes which use cream cheese instead of the egg but it seemed better this way) 3/4 cup sugar (I mixed normal and confectioners sugar) 1 teaspoon vanilla extract 1/2 teaspoon salt 225g butter....

Since I migrated to Xfce it seems thunderbird does not uses the default browser setting nor the /etc/alternatives/x-www-browser. The solution to change the default browser to chrome for example is to go to Preferences/Advanced/Config editor and change the network.protocol-handler.warn-external.http to true. This way next time you will open a link you will be prompted to select a browser and you can choose to remember the setting. Comments: ghantoos - Apr 1, 2012 Thanks for the share!...
