TeXlipse

Standard LateX editors are optimized for small screens. But we are in 2012 and have big screens and your next monitor or laptop screen will likely even have larger resolution. The eclipse-plugin Texlipse takes advantage of this and provides an IDE for editing LateX documents with a real-time preview.

So, unless you have netbook, get the plug-in at http://texlipse.sourceforge.net/.

“Ping” a specific port

“Cannot connect to server”, but why?
First diagnosis is usually trying to ping the server, however sometimes it is useful to check if a particular port is reachable from your computer. So these are your tools:
  ping
gives you information if the server is up and on the time a packet needs to travel to the server and back
  nmap -v -A host
scans all open ports on the server and lists them. Useful to check which services are running.
  telnet host port if the port is reachable, the answer looks like this
    Trying 123.123.123.123...
    Connected to filesrv.nes.aau.at.
    Escape character is '^]'.

Instead of telnet, any other terminal program (for example putty) can be used as well.

Getting royalty-free images

Are you in need for free photos to be used in a presentation or publication? The internet is full of pictures of all kinds, but most of them cannot be used without paying a fee or infringing some copyright.

Noteable exceptions are wikimedia.org, the multimedia database of Wikipedia and freedigitalphotos.net, which offers royalty-free low-res images (400 px width).

You can limit your google picture search (which comes with a nice customable preview) to one of these sites by adding a “site:wikimedia.org” to the search field.

Telling Eclipse to ignore .svn folders

eclipse usually builds the .class files in a seperate binary folder named bin. Therefore it copies the directory structure and files from the src folders, which means that eventual .svn folders are duplicated in the bin tree, leading to irritation among subversion clients such as TortoiseSVN.

In order to overcome the problem, you can add .svn as a filtered resource. Open the properties dialog for your workspace or for your project, go to: Java Compiler | Building and add “.svn” to the list of ‘Filtered resources:’ under ‘Output folder’.

Shutdown/Restart using Remote Desktop

When you are using the Remote Desktop protocol to control a remote Windows computer, there is no option for Shutdown or Restart in the Start Menu.

If you actually want to restart the remote machine, you need to do press CTRL-ALT-END (STRG-ALT-ENDE on german keyboard) and then select either Shutdown or Restart.

Collaborative online writepads

You probably know this situation: you are in a chat or a telecon discussing some subject that needs some writing/showing to your communication partners.

Thanks to Web 2.0, there exist several solutions to that problem:

  • you could collaboratively edit a google docs document
  • for a simple and quick solution for editing plain text you can use

    They work without registration – just send your partners the link to your pad

  • or CollabEdit if you want to discuss a piece of code with syntax highlighting (no registration required)
  • or, if you need to include drawings and images, there is CoSketch that can also be used without registration

Of course, all these services are hosted externally, so you have to consider, what secret information you might disclose by using one of these services. However, there might be the same issue if you are using your whiteboard in your office without cleaning it afterwards – only that the cleaning lady might be less interested in your secrets than google and others.
