Archives for the month of: April, 2009

I’ve had some fun the past night or two helping out a couple of guys on a couple of cool projects. I’m not much of a cartoonist (wish I was) but it was great fun sketching some ideas up and making them come to life in Inkscape. It’s never been something I’ve been really interested in, but after the great fun I had doing these I think I’ll spend more time on stuff like this. You can probably see lots of places where my skills need work.. but if you don’t try you’ll never improve.

First, I came up with a fun little logo/mascot to help out rowinggolfer, who is trying to solve his proprietary (aka Crap) software problem at his dental practice. He (along with many other dentists apparently) are stuck with poor quality and poor service when it comes to their expensive dental database management software. After trying to help them solve the problem with constructive feedback and getting nowhere, rowinggolfer has decided to bite the bullet and create his own open source solution. Check out the OpenMolar project to see what he’s up to. Here’s what I came up with for him:

Another fine project I’ve recently helped out on is the newly created freelinuxbox.org site. Created by Linc Fessenden, one of the original hosts of TLLTS,  freelinuxbox.org is a great site that tries to connect up people who want to give away fully functional computers running open source software to individuals who need a computer, free of cost. Absolutely awesome idea. I had fun creating this one too.

Just noticed this post about “35 Tutorials to create amazing Vector Graphics using Inkscape” come across Twitter. And while I was quite happy to see a post aggregating some great tutorials on Inkscape, I was a little bothered by the blurb at the top of the post itself:

Inkscape is a free vector graphic design alternative software similar to Adobe Illustrator and CorelDraw, only it doesn’t cost you a penny. It is maybe not as powerful as its higher priced rivals, but certainly powerful enough to design high quality vector graphics.
If you are looking to venture into vector design, I recommend using Inkscape first, learn as much as you can and then if you need something with more kick splash out on Illustrator.”

Why does there have to be an immediate proviso that somehow it’s not as powerful? The last sentence is even a little more bothersome to me. I can see someone saying, ‘hey, learn all about vector illustration with Inkscape, it will help you if you ever have to use Illustrator or CorelDraw’ or something like that.. but I really don’t see how using Illustrator is going to somehow give my work more ‘kick’.

If you need something with more kick.. then obviously you should sit in front of whatever you’ve created and give it more kick. I can’t stand the insinuation that somehow if you need higher quality artwork, you’d obviously have to go with the paid option.

While recommendations for free software alternatives are increasing daily (or it seems to me that they are), it bugs me that they always seem to come with a proviso. And sure, while in many cases those cautionary notes are completely valid, in other cases they are not.

Rant over. ;)

About 6 or 7 months ago I was invited to submit some logo concepts for the SouthEast LinuxFest. I was absolutely thrilled that they chose one of my submissions. Since then, I’ve done a few ancillary things with the logo such as a flyer design and some web site badges.

The venerable Dave Yates of the LottaLinuxLinks podcast is one of the organizers of the event. Several weeks back he asked if I could provide a couple of print ads for the event and I was thrilled (and to be honest, quite nervous) about accepting. There was something a little nerve-wracking about creating something that will actually appear in a publication. It’s one thing to create some web site graphics or desktop wallpaper, but it’s another to actually create a print ad… at least for me. I’ve never created an ad before but it actually turned out to be quite easy.

I created a half-page ad for Linux Journal (which you will find on page 55 of the May 2009 issue of LJ) and it turned out quite well I think. I created the graphic for the ad in Inkscape (of course!), exported the PNG file and then made a CMYK TIFF version using the Separate+ plugin for the GIMP. From there I used Eckhard M. Jager’s fantastically useful CMYK Tiff 2 PDF plugin to create a PDF in CMYK. Like most things I try, it was a real seat-of-the-pants sort of process for me.

Eckhard by the way, has a really fantastic blog called appropriately enough Linux For Designers. I’ve been subscribed to it for ages and I encourage anyone interested in design on Linux to check it out. There’s lots of great stuff over there.

The fact that I know absolutely nothing about CMYK or creating print ads is a testament to how useful those two plugins really were to me. It was satisfying to know that I could really create an honest to gosh print ad using free software tools and come up with what looks like a decent result.

There is another full page SouthEast LinuxFest ad I created that is supposed to run in the next two upcoming issues of LinuxPro Magazine too, so keep an eye out for them. Hopefully my sparse knowledge of CMYK will not fail me in those ones either. :|

While to most people they’ll just be another (hopefully attractive) magazine ad, to me they’re definitely getting stored safely away so I can brag to my grandkids about them someday. :)

eyestillBack in February or March, my trusty Flip Ultra camera stopped working. Granted, I wasn’t being all that careful with it, even thowing it into my coat pocket along with my car keys and other stuff. Shame on me really. I was disappointed that it died, under the manufacturer’s instructions I took out the batteries for 72 hours and hoped that a full cold reset would do it, but she was a no-go.

So facing a week long trip down to Myrtle beach at the end of March, I decided to buy another low cost video camera. I was looking at the Flip Mino, but it was nearly $300.00 up here and just didn’t look like something I should be spending all that money on. I was heading back to the Flip Ultra at $158.00 but then noticed that Best Buy was selling the Kodak Zi6 for about $168.00. It had significantly higher resolution than the Ultra and sounded like the build quality was a step above. I bought the Kodak, and a month later, I have to say I’m quite impressed.

The build quality does seem to be a significant step up from the Flip Ultra. It’s significantly heavier and wider but has a much larger LCD screen on the back and a much more durable feel to it. Slightly scared because of what I did to the poor Flip Ultra, the new camera has been shuttled back into it’s velour pouch every split second it’s not it use. Slightly paranoid I guess.

The Kodak shoots in (technically “HD”) 1280x720 at 30fps or at 60fps. It will also shoot in VGA (640x480 like the Flip Ultra), and it will take 3MP still shots. I have largely stuck with the 30fps 720p mode, but I’ve also taken a few stills which have not disappointed me too much either.

Clearly though, this is not a $1000 camcorder. I find the quality to be quite good, but it’s very lighting dependent. Although as many people I’ve discussed this with mention, almost any consumer camcorder loses significant quality in low light conditions. The Kodak is much the same and probably worse. I’ve used it happily indoors under normal lighting conditions, but of course like any handheld video camera (or still camera), it really shines when outdoors or under good natural lighting.

The camera is almost as simple as the Flip Ultra was. It has a nice flip out USB plug, and get’s detected in Linux as a mass USB storage drive. Very simple. It does let you fast-forward and rewind through videos under playback which is nice as well. Unlike the Flip Mino, this camera uses 2 AA batteries. And even nicer is the fact that for $168.00, they give you a nice pouch, two NiMH batteries AND a charger for them too! Yes, daddy.. indeed the batteries ARE included with this toy. However the SD card it stores video on was not. Luckily I had a 16GB SD card that my wife recently received at some company shindig. I never had a use for SD cards before this (my DSLR uses CF), so it was just good luck for her to have it at the same time I needed it.

Note also that the camera has a macros switch for close-up work. I’ve rarely used it, but I have included a still shot I took earlier today of my daughter’s eye. You can see it’s quite nice and you’ll notice the reflection of the Kodak right in there too. :)

It ain’t all rainbows and flying ponies though. There are two things which may cause a little concern…

First, the 1280x720 video is quite nice. Nice enough that it wouldn’t play back smoothly on my 5 year old P4 desktop system (even with a 7 series NVidia card). However on my new laptop (a Dell Studio XPS13) it plays back full screen just beautifully. So it may be great to shoot HD resolution video, but be aware that you may not be able to play it back in full resolution if your computer is getting somewhat long in the tooth. Once converted down to something smaller like 720x405, my P4 system played it no problemo.

Second, the video it produces is in MOV format. That is, it’s really h264 with AAC audio encoding. This is fine for many people. However if you’re interested in editing this video in Blender, you may want to re-encode the audio to something that the current stable version of Blender likes more (like MP3). You can do that using ffmpeg like this:

ffmpeg -i input.MOV -vcodec copy -acodec libmp3lame -ab 128k output.MOV

Blender will then happily accept the video and audio for editing.

I’ve included a few sample files in this blog post for those interested in evaluating the quality of the video and images. Note that the video sample is done under what might be the best quality light for a cheapy camera… overcast conditions. Your mileage will vary under more harsh lighting conditions. The camera is not lightning quick to in moving from dark to light spaces, but what do you really expect for a sub $200.00 video camera. The normal still shot is indicative of a tiny sensor. The light is fairly harsh so you’ll see a significant loss of detail. This won’t match a good 3MP point and shoot, but it might be better than your average cell-phone camera under these conditions.

I’ve included an original full res video clip (30 sec and about 30MB), another sample full res clip with the audio re-encoded to mp3 using ffmpeg above, one short macro video sample taken of the CD player display in my car (dust and scratches anyone?) and two sample full res images, one macro and one normal.

And although this didn’t play a part in my choosing the Kodak, I would be remiss if I didn’t point you to Troy Sobotka’s video which he shot with this Kodak Zi6 and edited in Blender. Just to show you what even a cheapie camera like this can do when in the right hands.

As I found with my Flip camera review way back when, there usually aren’t a lot of people willing to post a full res video sample, and I can’t see the usefulness in reviewing a camera and then posting a YouTube sample for people to evaluate. Hopefully it helps some people thinking about purchasing a cheapy video camera like this.

A few days ago at the suggestion of my trusty pal Heathenx, I downloaded and installed Portable Ubuntu. I must say, I’m quite impressed.

I’ve used Cygwin for quite a while now to get a bit of my Linux fix while working on my XP-Pro box at work. I use it mostly to run a proper bash terminal so that in concert with Dropbox, I can use the fantastic Task command line todo list management tool ubiquitously between computers at work and home. But I’ve always wanted to run things like Gedit, or other Linux based stuff here at work. I once tried getting Cygwin/X running here to achieve some of that but could never seem to put the pieces together and get it working.

I also run #! in a VM for more heavy duty Linux needs (and incidentally I’m now running #! full time on the new laptop and I’m loving it!), but I don’t always want to have to fire up Virtual Box whenever I want to use Gedit.

In steps Portable Ubuntu. With it I get a nice standard Ubuntu menu with a smattering of basic apps, but I now get access to Synaptic, the repos, and who knows what else. I would be surprised if there weren’t some limitations, but so far it seems pretty darn good. I’ve taken a full size screenshot of my desktop at work (1920x1200) showing things like synaptic and gedit working side by side with AutoCad and Chrome. I’ve got the Ubuntu menu over on the left with Auto-Hide turned on so you can’t really see it there.

Anyways, if you’re stuck in a Windows world at work, but want a nice way to mix in some Ubuntu goodness, then give it a shot. The whole shebang actually uses the Xming X Server which I believe is the thing I could never get working with Cygwin/X. But Portable Ubuntu seems to have done the trick.
