MythTV "streaming"

I was amazed to see how well the MythTV backend could stream to the MythTV frontend via wifi.

The setup doesn't seem to lag and it even seems to play better than streaming a file directly from the backend into VLC or mplayer.

Cisco SVG

Guess what? So I have a post where I converted the Cisco Networking Icons in EPS files into SVG. I recently noticed that Cisco was offering them in SVG format.

After downloading them to try out I had noticed that although they were in SVG, they were odd in that they basically where a small icon in the middle of the full page. They have a feedback link at the bottom so I proceeded to ask if I could make the changes to the SVGs to resize them as well as add metadata for the SVGs.

Well, Cisco got back to me. I managed to explain how I converted the files and what did I find today? Cisco had updated the SVGs and now they're right. Thank you Cisco.

I'd like to thank the person that responded, but I don't know if they want their name floating around the web, so I won't mention them. However, thank you!

Now, to draw some network diagrams.

What's the difference between a bank and a swing band?

I was reading a new article today on the Telegraph which I find absolutely crazy.

It's about a swing band called Wills Fargo being harassed by the bank Wells Fargo.

I don't know about you, but unless the band starts asking for deposits and gives you a cash machine, it starts using the same red box with yellow letters and includes the stage coach as part of their logo, then WTF!

I hate this type of stuff. There is absolutely no overlap in ANY way. Next we'll get sued for using the letters W and F because they're part of the name.

I can understand brand dilution (Wills Fargo Bank), I can understand fraudulent use, I can understand a lot of stuff, but this goes beyond what should be allowed.

Ubuntu 9.10 issues and solutions

One of the major issues I have had with my Macbook Pro and Ubuntu 9.10 relates to virtual machines and Virtualbox. My virtual machines would freeze for a few seconds (10-15 seconds) then do some more work, then freeze again for 20-30 seconds, then some more, then freeze, then go, then freeze...

This drove me nuts! I run XP every once in a while and it was so quick on Virtualbox prior to the upgrade that I thought VB was the culprit.

I messed around with the settings, I turned things on and off; all to no avail.

Then I remembered a post somewhere that mentioned the video drivers. Not the virtual machine's virtual video driver, but the actual driver of the host machine.

So I looked at what I was running.

Nvidia's driver version 183 - which was suggested and recommended by Ubuntu 9.10 after the upgrade. It worked fine with everything I did... could it be the culprit?

I then swapped the driver to version 173 which I was running previously (that reminded me I tried 180 and had problems with virtual machines then too) and my XP virtual machine was happy once again.

I did experience an issue or two with my machine freezing (the whole thing, not the VMs) after doing this and thought it was the Nvidia drivers again.

However I noticed something interesting. The freezes occurred only when I had Firefox running. If FF wasn't running, everything ran smoothly.

So I went into the FF add-ons and thought about how a "new" add-on I had installed and almost never used would actually use cool 3D effects. I'm talking about FoxTab. I disabled that after 20 minutes and guess what?

My virtual machines are happy, my Macbook runs smooth as silk!

Now to troubleshoot something else... OpenVPN on NetworkManager.

Mythbuntu 9.10

I finally managed to update my MythTV server up to 9.10 of Ubuntu. Although I didn't install it from a Mythbuntu CD when I did the first install - it's now a Mythbuntu installation.

What can I say about this?

MythTV 0.22 (the normal app is 0.22RC2, I think in ubuntu it's 0.22+svn fixes)

The new MythTV is NICE! I still have some issues. I'll document them here and any solutions that I find. There are several things that I need to do to get them working right according to the MythTV wiki.

For now, I'm updating the graphics of the videos and I'm trying to tune all the different settings that you can use.

All in all, I think it's great!

Visio and Linux or what I call "Want SVG, use PDF"

I tend to get Visio diagrams from people every once in a while. Most of the time it's the vsd type, not even the xvsd (or xml based) version. Even if I had the xvsd, I'm not sure what exactly I could do with it.

Visio does have the capabilities of exporting to SVG (at least the latest release does) but I find that they don't import properly into Inkscape. It's strange but they seem to display properly elsewhere.

The answer to this issue? Another intermediate step -- use PDF. Visio can also export to PDF directly. (Or maybe you need a plugin?)

This PDF renders correctly and when you import it into Inkscape it shows up correctly too.

Now to test another file type... Visio can export into Autocad format!!!

I just recently discovered that you can convert DWG to SVG. I haven't tried the Cad2SVG tool yet, but I'm hopeful it will also provide an SVG that's usable in Inkscape.

By the way, if you're wondering why I'm so eager to go with SVG? It's simple -- it looks good and you can zoom without losing detail (very handy with an iPhone!) And if you don't believe that there's a lot of SVG out there, check out
