Solution: No popup for Skype Incoming Calls

I recently updated my Ubuntu setup, which involved upgrading to 14.04 and also moving my monitors/laptop screens around. An unwanted side affect of this was that when I was receiving an incoming Skype call I wouldn’t see the usual popup alerting me. This meant that although I could hear the ringing, I could not answer the call. The issue was that the popup was appearing off screen rather than it not appearing at all. A quick search led me to this post on the Skype forum that mentioned a solution through modifying the ~/.config/Skype/Skype.conf file. This file (or mine anyway) contained lines that look like this;

position=@Point(58 400)

By modifying the values I could easily adjust where the call notification would pop up. There’s also a handy Test Event button in the Skype Options tool which means you can simulate the incoming call to see where the popup appears.


Salesforce Meetup – MavensMate

As my final days at EE come around, I’m starting to make some headway in getting to understand more about the architecture and nuances of frontend development and the associated frameworks. Hand in hand with this education also comes an implicit syllabus relating to the development workflow, and in particular the tooling that’s available. I wrote about a JS tooling workshop I attended in this post and this week I attended one of the Salesforce developer meetups and there we also covered tooling, specifically David Helmer talked about MavensMate and how that can be used in Salesforce development.

Like the previous events that I’ve attended the meetup was held at the Make Positive offices and once again they were great hosts and sponsors, supplying beer and pizza, just what the doctor ordered.

Mavensmate is a plugin for several IDEs, most commonly used with sublime but there are plans to also include support for too in the near future. Essentially it gives developers an open source, apex IDE.

Primarily built and supported by Joe Ferraro it’s a cross platform tool that gives Salesforce developers a tool to match those available to developers who are using other languages such as PHP and JavaScript.

David kicked off his talk by announcing that it’ll take the form of a live demo…. there was the inevitable feeling in the room that we could be in for some good-ol squirming. What followed though was anything but, thanks it seems to the wonderful features of, not only Sublime Text, but also Mavensmate itself.

Demonstrations of many features were presented. Key ones (read those that I made a note of and can remember) were;

  • It’s open source… pull it and contribute
  • Editing and compilation of apex code (via platform)
  • Resource bundle handling and uploading
  • Templating
  • Auto completion of functions and variables
  • Apex Testing – And whilst your tests are running there’s a whole host of games you can play (pacman etc), genius
  • Anonymous apex (exec) – runs ad-hoc code platform.
  • Project meta data can be pulled down viewed
  • Fetching debug logs

See the MavensMate documentation pages for more information.

I had tried previously to get MavensMate running in Sublime Text 3 on Ubuntu, but without luck… but I’ll certainly be trying again and will contact Joe if I’m still having issues.

Sadly I was unable to hang around and chat with the other Salesforcers, they’re a good bunch and it was a shame not to catch  up with them… hopefully next time.

Easy coloured tail output

As part of my job I’m often watching the output of a tail -f <filename> command run down my terminal window… and on my development and quite testing machines this is all well and good.

But what if the system is a pretty busy one? Well here it can be hard to spot the messages that might be of interest to you. And that is why I use a little trick to highlight a specific word in the output.

How to highlight words in tail output?

1) Basically add the following lines to your .bashrc  file

  tail -f $1 | perl -pe 's/'$2'/\e[1;31;43m$&\e[0m/g'

This adds a function available to you in bash that can be then be used to do exactly what you want. Say for example you want to highlight all instances of Error when tailing a file called foo.txt you can run the following.

ctail foo.txt Error

Rebar/Git Error and Solution

Just a quick one… for my benefit as well as perhaps yours.

I was trying to use rebar to pull in the dependencies on one of my Erlang projects but it kept failing with the following type of output;

fatal: could not read Username for '': No such device or address

I believe rebar doesn’t know how to ask for github credentials and I solved this by using the git credentials helper.

git config --global credential.helper 'cache --timeout=3600'

Ubuntu 2d – Some tweaks

Recently my install of Ubuntu on my work desktop started complaining about now being out of support… so I decided to upgarde to the latest LTS version (Ubuntu 12.04). Overall the install went fine apart from a couple of little things that I needed to address

Desktop size to big for Unity 3D

Sadly my graphics card did not support running Unity 3D across my dual-head setup (2 x 24 inch monitors). This, I didn’t feel, would be too much of an issue as I wasn’t too interested in all the desktop eye-candy. All I did here was then choose the Unity 2D option at the login prompt.

The 2D setup itself was not hassle free though;

Quick Synergy, Very Laggy

I noticed that for some reason the usually great Quick Synergy (which I highly recommend if you want to share mouse/keyboard across multiple PCs… including different OS) was very laggy. This was not the case if I used Unity 3D in mirrored monitor mode or if I used any of the other Gnome desktops at login. I had no luck in finding a solution to this… that was until I decided to solve my next issue… read on for the Quick Synergy lag issue solution.

Terminal Window Always on Top

I found that the Terminal windows always remainded on top (in front of) other windows I had opened. Now I’m the kind of guy that uses the Terminal a lot, so this was going to be a show-stopper if I couldn’t find an answer.

After a brief search I came across this link which details a solution. In essence it just tells you to disable metacity from being the composting manager (and how to do it too).

I’m not sure what adverse side-affects might be suffered from this… so far I’ve not noticed any. One good bi-product of this chnage though was that Quick Synergy sped right back up again and became super-responsive once more… WIN!
