ffmpeg encode for Powerpoint Viewer 2010

You setup a powerpoint presentation on your normal work machine, the encodes you did in mp4 worked just fine in the presentation. Save out to a stick and take it to the machine (an all in one touch screen 65″ with powerpoint viewer only) and all you see is a black screen where your video should be.

Scoured the interweb and tried three different encoding solutions, all of which resulted in a black screen.

I then upgraded the powerpoint viewer on the display machine from 2007 to 2010 (or the latest one I could find on the Microsoft pages). Bingo, the video started working.

Here is the encode I used which worked best, allowing proper full screen video, no black bars, etc.


Simple (quick and dirty) Multi-Part Archive using 7z and CLI

Sometimes simple is better. File Roller wouldn’t create a multipart no matter what i tried so I turned to cli for a solution, and found it with 7z.

In this case I need to archive a 1.2GB iso file to a four part archive, with a volume size of 300mb. I didn’t delve into all the intricacies of what 7z can do, just the basics.

This produced four files:


7z: calls the program
a: creates an archive
-t7z: selects 7z as the archive type (there are others)
-v300M: tells 7z to create 300mb archive parts
output and input files should be obvious. You could replace the input file with a directory!

will give more detail on options

Webconverger Customisations

I need to write up the top of this post about Webconverger, but have been busy figuring out all the useful options for it. In simple terms, its a locked down bootable kiosk. Very clever, works on 486 and 686-pae machines. Also here so I can browse this whilst booted into webconverger 😉

Automating Framebuffer Digital Photo Frame

dpf6We have seen in my previous post how I setup the DPF to work against the framebuffer. Now it was time to automate things a bit.

Task List:

  • Autologin on Startup
  • Start gnu screen on Boot
  • Uploading New Images
  • Screen On/Off Timer
  • Reboot Timer
  • Shutdown Timer
  • Unique names/shuffle for file list
  • Cycle Colour Change for Clock ?

Digital Picture Frame & Clock on the Framebuffer!

dpfBeen wanting to have a go at this for a long time, and finally found some time to sit down and hack my way through it. Everyone else on the web seems to have used X to do this, but encouraged by all the work done on the cli and framebuffer by KMandla I felt this could be done. Now I’ve done all the hard work, I am happy to share it with you!

Meld – saved me from myself!

Meld is a file/directory differencing programming (with GUI). (in the repos)

I was under orders to put together a new website for my work, and didn’t want to pay out for web designers, so I turned to Drupal 7 for the first time and had a play. Over the last couple of months, in bits of spare time, I tinkered and fiddled, setting up home pages, news pages, forums, sidebars and menus, getting the theme right. Lots of good help from the community, but ignoring all guidance about not fiddling with the “core”.

Anyway I got to a position where I could go “live”, so reorganised the domain forwardings, adjusted a few absolute link references and we were off. At this point my sysadmin brain kicked in (it’s very small :)). Back it up? What if Drupal updates overwrite all my work so far?

Am I Open Source or What? (on a Windows 7 PC ?)

It’s list time again:

Because so much good open source software has been ported to Windows, its possible to do just about everything on Windows with the open source programs I use regularly on my main Xubuntu 9.10 system:

Open Source:

Open Office
Gnumeric (a bit buggy)
ProjectX (java)
HJSplit (java)
Frostwire (java)
FireFTP (firefox extension)
Firefox (of course!)
Mplayer & SMplayer

This list will grow. Keep up the good work guys :)

Plus, some notable “freeware” applications:

AVGFree 9
Shark007 Codecs Pack
Windows Movie Maker 2.6
JellyBean Key Finder
Google Chrome
DeFraggler (Piritin)
Free Screen To Video (Koyote Software)
Winamp (with iAmp skin)
WizMouse (scroll without focus)
Powerpoint Presentation Viewer
RocketDock (just like my wbar!)
Adobe Reader 9
Scanner Application that comes with my Brother Network Printer (Brother very good at drivers and support for Windows and Linux)

[EDIT 12/2010 add DVD Flick to your list of freewares, encodes / authors / burns ]

Shareware I just can’t live without:


[EDIT 12/2010 – now found I can, try Izarc, copes with just about everything ]


Also done a few registry hacks to sort out the awful unintuitive default behaviour of Windows Explorer. These are easily found on any Windows 7 sites.

Remove Libraries from Explorer
Remove Favourites from Explorer
Remove HomeGroups from Explorer
Adding Directories “I want” to the SendTo drop down
Removing “Drives” from SendTo
Adding Copy To folder and Move To Folder to Right Click
Adding Open Command Prompt to Right Click

Nearly got my Windows PC behaving and looking just like “Linux”  😀
