I recently found this tutorial to convert the HC-SR501 PIR Motion sensor, to allow it to run on 3.3V, so I thought I would give it a try, to use it with my whisper node, and make it count the amount of people passing the sensor, trying to make it run on a coincell battery.
I was looking for a good way to group logs from different webapplications into one managable place, without too much configuration work on the different webservers, since some run on shared hosting, and some have different setups.
I came across Paper Trail App A hosted log management tool, which gives you the ability to aggegrate logs from different places into one location, and here you can filter and group different webservers together, and search the log history.
I have been using Telerik Platform for some time now, I was quite happy when using the trial, but since I have taken a $39 monthly developer subscription to create my mobile applications, I have had some great features gone missing 🙁

I made a simple shellscript it will:
- dump a few databases
- create a tar.gz from them
- scp a copy of the tar.gz to my backups folder on a remote server, this way I will always have a backup of my most important databases on a remote location.
mysqldump db_name1 -u myUser -pMypassword > db_namedump1$(date +%F_%R).sql
mysqldump db_name1 -u myUser -pMypassword > db_namedump2$(date +%F_%R).sql
mysqldump db_name1 -u myUser -pMypassword > db_namedump3$(date +%F_%R).sql
tar -czf ./backups/$FILENAME *.sql
scp ./backups/$FILENAME backupusername@myRemoteServer.com:backups/
Just save it in a file, and add it to your cronjob (crontab -l) I run it every 4 hours, by adding this to my crontab:
0 */4 * * * /home/user/db_backup.sh

I’m working on a small project for a client who uses a shared hosting environment. In order to use some sort of versioning, I setup git-ftp so I can work on my development server and push the changes with git-ftp to the shared hosting ennvironment. This way I will not need to do any manual file picking and uploading. After the first git-ftp init command (where it will upload the complete folder) you can git-ftp push, so it will only push the changed files from the commits.
I had a small hickup setting it up, the git-ftp init would hang for 15 minutes and then display an error, so I ran it again with git-ftp init -v to see what was going on, turns out it connected but default git-ftp tries to use epsv connection, which wasn’t supported, so it was just connecting showing connected, with last message TYPE A, and them waiting for a response and timing out after a set time.
in order to run in PASV mode directly you can use git-ftp init –disable-epsv
Mailchimp is a great and versatile web application used by lots of websites, it’s easy and secure. But correct implementation by the developer is needed to keep your subscriber data safe, with so many users using Mailchimp, it’s imporant to correctly implement mailchimp security.

The Talk2 whisper nodes are low powered boards based on the Atmel AVR ATMega328p microcontroller. This board can be powered with as little as 0.9V. You can even run it o a CR2032 battery for a long time with correct coding.
