Start dropbox at reboot in linux

I was having problem in my ubuntu machine that the dropbox was not running, because it did not started at reboot. The command dropbox autostart y did not work, and I tried it running as root or my normal user.

So to solved it I decide to use cron, so I run crontab -e and add the line

@reboot $HOME/.dropbox-dist/dropboxd

This did it, now I get dropbox running after a reboot.

Configure postfix to accept all email addresses

There is a solution in http://serverfault.com/questions/514643/postfix-accept-all-email-to-any-user-at-any-domain reporting a solution similar to what I needed.
I'm running raspbian so I think a some things are different, another difference is that I only want to accept addresses to my domain.
The solution was:

1.  Create the file /etc/postfix/virtual with the content:

   /.*@example.com/ spamuser

2. Add the following line in file /etc/postfix/main.cf:

   virtual_alias_maps = regexp:/etc/postfix/virtual

3. Activate the virtual file: postmap /etc/postfix/virtual

Additional notes:

• The solution in serverfault suggested to use virtual_alias_maps = pcre:/etc/postfix/virtual, with this line I was having the following warning:

  error: warning: pcre:/etc/postfix/virtual is unavailable. unsupported dictionary type: pcre.

  Apparently my install was expecting regexp instead of pcre. To find out the capabilities of your install you can run the command postconf -m
• To check the status of the service run service postfix status, you will also get a tail of the log, was useful to see configuration errors.

Garming GPS dowload Maps to SD instead of device

Create folder \Garmin on the SD card.
Copy the file garmindevice.xml from \Garmin folder of your device into the \Garmin folder of the SD card.
Run the Garming express , it should detect the SD card as a Garming GPS.

The map files will end up on the SD card in folder \.system and will be named gmapprom.img, gmapprom.unl and gmapprom.gma. Create folder \Map on the SD card and move these three files into it. You can then rename the files from gmapprom to any name of your choosing, but keep the .img, .unl and .gma extensions.

If your device has junction views, you will find a JCV folder within the \.system folder on the SD card. Move the JCV folder and its contents into the \Garmin folder of the SD card.

All the Special Key Combinations that Change Your Mac's Startup

From http://lifehacker.com/all-the-special-key-combinations-that-change-your-macs-1761327018

• Shift: Starts your Mac in safe mode. This helps you troubleshoot because it only loads the minimum necessary kernel extensions at boot then disables startup items, user-installed fonts, font caches, kernel caches, and other system cache files. Safe mode also runs a file system check automatically, which should help with troubleshooting. 
• Option: This loads up the startup manager where you can pick between different hard drives or discs to boot into. If you need to boot from a hard drive different than your primary one, or you’re booting into Boot Camp, this is the key you push. 
•  C: Boots from a bootable CD, DVD, or USB. This is useful when you’re installing a new operating system. 
• D or Option+D: Starts the Apple Hardware Test on pre-2013 Macs or Apple Diagnostics on newer Macs. Both are meant to help troubleshoot hardware issues. N or 
• Option+N: Starts up from a Netboot server. Most average users will never need to use this as it’s meant for running OS X off a network instead of a hard drive or disc drive. 
• Command+R: Starts up in Recovery mode. If you have problems with your hard drive, OS X Recovery allows you to restore your Mac from a backup, verify and repair your disc, check your internet connection, or reinstall OS X. 
• Command+Option+R: Starts up the internet version of Recovery mode, which works the same as regular Recovery mode, but is online. 
• Command+Option+P+R: This resets the NVRAM. NVRAM stores information about speaker volume, screen resolution, startup disk selection, and recent kernel panic information. If you’re having issues with sound or video, it’s usually a good idea to reset the NVRAM before panicking. 
• Command+S: Starts up in single-user mode. This is meant mostly for developers and IT as a means to troubleshoot startup issues and basically drops you into the command line where you can run tests without worrying about the GUI in OS X. 
•  Command+V: Starts up in verbose mode. Verbose mode is similar to single-user mode but is meant more as a way to watch what a computer is doing to help with troubleshooting. 
• T: Starts your Mac in target disk mode. This is a useful way to share files between two Macs when one of them is broken or the display isn’t working. 
• Eject button, F12, mouse button, or trackpad button: Force eject an optical disk.

Chose user used by samba

Problem:
I wanted to have a samba share with guest access, and the user used by samba to write on the server to be a specific user account, so that I could also manipulate the files placed in the share.

By default the user used was nobody, and the I was having problems using the local linux account in the server to manipulated files, as it did not have the correct access rights.
The option that solved my problems was:

[Share]
path = 
writeable = Yes
force user =  # this was the line that fixed the nobody user
guest only = Yes 
guest ok = yes
browseable = Yes
public = yes
hide dot files = no

The problem I was facing was the install crashing and not able to finish. Looking I found a blog, the solution that worked for me was :
Disabling "Nested Paging" in Setting->System->Acceleration allows to start the system.

How to change default application in a website in IIS

The solution to set one application as the default for when you hit a website is to change the website Physical folder, to match the application root folder. As explained in a Server fault post.
Another hack-around is to put a index.html page in the root of the site performing the re-direct.
Using the redirect feature of ISS can cause trouble with you application, I recommend against it.

The best answer form me is:

Turns out you can edit the physical path of the Default Web Site (right click, Manage Web Site, Advanced Settings). Change that to the physical path of the app you want to be default, make sure other settings match (in my case the App Pool had to be changed), and there you go.
