Quick link to edit the hosts file on windows 7

By |2011-06-27T11:22:14+00:00June 27th, 2011|Uncategorized|0 Comments

If you edit your hosts-file often it can be practical to have a shortcut that opens the file in a texteditor. This is how you would create such a shortcut on windows 7: Create a normal shortcut to the program notetad on your desktop. Edit the target of the link by adding "%SystemRoot%\system32\drivers\etc\hosts" at the end. That way the target of the link will be something like: "%windir%\system32\notepad.exe %SystemRoot%\system32\drivers\etc\hosts". When you use the link you [...]

Creating 301 redirects between many pairs of URLs

By |2011-06-21T11:17:01+00:00June 21st, 2011|Uncategorized|0 Comments

I recently upgraded a website. The website consisted of static html documents and some simple php scripts. I transformed it into a wordpress blog. In this process every url was changed. In order to keep the pagerank and not break any inlinks I created 301 redirects between them. If there had been an obvious pattern between the old and new urls this would have been a simple task. For example lets say urls of the [...]

Reading browser saved passwords

By |2011-04-04T17:01:00+00:00April 4th, 2011|Uncategorized|0 Comments

Assume you forgot you gmail password but you allowed the browser to remember it for you. You can still log in as the browser fills out the password for you, but you can not find out what the password is as all you see is some stars or dots. The situation is cool for now, as you can log in, but as soon as you clear your browser cache the brower will forget the password [...]

Creating a Minecraft SMP Bukkit Server

By |2012-02-19T21:00:58+00:00March 23rd, 2011|Uncategorized|0 Comments

Get a VPS In the long run you should use a VPS instead of hosting on your own computer. This way you can turn of your computer at home and still be able host the server 24/7. The server should have at least one gigabyte ram. The server should not use OpenVZ for virtualization. It would work but you might face memory allocation issues. You should go for Xen virtualization. In the continuation I will [...]

My server setup checklist

By |2015-09-08T15:18:51+00:00March 23rd, 2011|Uncategorized|1 Comment

This is the checklist I follow when I create a new Linux Debian Server. The goal is a safe shared hosting environment where every user can ssh to the server but no user can see the content of another users home folder. Setup language You need to setup language if you get error messages like this one [crayon-5e59d85ab8ba1603076878/] Run the following two commands to solve the issue: [crayon-5e59d85ab8ba6373669686/] File Permissions Files should be restricted to [...]

I like .gitconfig

By |2011-03-28T11:43:09+00:00February 8th, 2011|Uncategorized|0 Comments

If you use git from the command line you can improve your usage experience by altering your git config file wich is called ".gitconfig". Find that file in your home folder. You can for example turn on color and add some handy shortcuts. Here is what I use: [crayon-5e59d85ab900c714768119/] It is also possible to alter the gitconfig from the commandline. The settings above would then look like this: [crayon-5e59d85ab9013349454090/]

Free SSL certificates without the browser warning? Yes! It’s possible!

By |2011-03-28T11:48:20+00:00August 7th, 2010|Uncategorized|0 Comments

When I need SSL encryption for some admin panel on one of my websites I usually use the snakeoil certificate that comes with the installation of the ubuntu OS (/etc/ssl/certs/ssl-cert-snakeoil.pem). But I can not use this method for a serious web page where I would like to provide ssl for the visitors. The browsers will warn as the certificate was not signed by a well known certificate authority (CA). The reason you might not want [...]

Backup your database with mysqldump

By |2011-06-13T07:48:58+00:00August 4th, 2010|Uncategorized|0 Comments

Using Automysqlbackup I recently decided to take backups of my mysql database and I found a very good solution for this: http://sourceforge.net/projects/automysqlbackup/ Automysqlbackup is a bash script that uses mysqldump to take daily, weekly and monthly backups of your database. I found many bash-scripts while searching but this script was the best one I found and it is even in the Ubuntu repositories :) To install: [crayon-5e59d85ab932c049172913/] Per default it saves the backups to /var/lib/automysqlbackup [...]
