New Overlay for Syscomp Design

I recently used my digital storage oscilloscope and  function generator for the first time since retrieving all of my electronics from storage after returning from Germany. These are really handy devices for examining low-frequency (pre-micro) electronics. After I wrote a couple of ebuilds to install the Open Instrumentation Project software, I thought I'd make the ebuilds publicly available.

Syscomp Design is incidentally run by a former professor of mine from Ryerson, Peter Hiscocks. I thoroughly enjoyed his course on microprocessor / microelectronic interfacing, and luckily did so before he went into early retirement. On a somewhat unrelated note, we're both part of the TLUG :) It's good to see that Prof. Hiscocks is keeping himself busy these days - Syscomp just released a new device that obseletes both of the units I bought 3 years ago! Although he mentioned that the older oscilloscope circuit has more dedicated storage space and time resolution.

If anyone would like to check out the overlay using layman, then you should be able to do it with the following command

layman -o http://virtb.visibleassets.com:2080/layman.conf -a syscomp

After that, you should be able to do the following (as root)

for i in dso101 cgr101 wgm101; do
echo "sci-electronics/$i" >> /etc/portage/package.keywords
done
emerge -av1 dso101 cgr101 wgm101

I've contributed two patches (one for wgm and another cgr) which allow for more flexible storage of the program files in /usr/lib.

Enjoy!

My Ideal Laptop

It's come to the point that I'm considering upgrading my laptop - but I haven't seen anything on the market that's ideal for me. If you know me personally, you would know that I have been a bit of an environmental nut since I was 10 years old, and that I am also an electrical engineer, embedded systems engineer, and completely obsessed with Linux. As such, I have some pretty interesting ideas of what the 'ideal laptop' would mean to me.

My ideal laptop would be one that is highly portable, environmentally friendly, and energy efficient but with a fair bit of number-crunching and graphics processing power. It should not be assembled or manufactured by poorly treated employees either. My final and least-likely-to-be-realized preference is that my ideal laptop would also be one that could be tracked if stolen[2]. It also goes without saying, that my ideal laptop would utilize hardware with open-source drivers so that one would not be stuck with any inferior, proprietary operating systems.

Throwing all of those ingredients into one pot makes for a fairly difficult main course. The question is, which company will possess the techno-culinary expertise to prepare the appetizers?

There has been much more debate and demand for environmentally friendly computing products than someone from an older generation would think[1]. However, many of the Y-Generation were brought up during the 80's when the environmental movements really began to boom and, therefore, have a much more intrinsic concern about environmental impacts.

On the other hand, the anti-theft system (ATS) is still a relatively new concept. I have personally taken it opon myself to design an personal area network (PAN) ATS for valuables such as electronics or cycles, but between my engineering job, my master's education, and now my baby on the way, I no longer have a plethora of free time for dreaming up gadgets and new designs.

List of Similar Laptops & Shortcomings

Dell Latitude D430:

If one navigates to the Dell site and selects the small business / notebook links, one would notice that there is a small image that says 'Windows XP Optional'. When the visitor proceeds to customize the notebook, Windows XP is, in fact, non-optional. Dell, take off whatever the price is of Windoze these days and offer an operating system free and / or Linux installation. Then I might consider buying this notebook.

Dell, I do very much respect the step forward by offering solid-state media instead of magnetic storage. Although the $1000 jack in price seems unfounded, especially when Transcend has such excellent deals on a solid state disk at the moment, like the ones here and here. At any rate, if I could purchase this notebook without Windows and without an internal optical drive, then it would be a done deal, and I would just buy the flash disk from Transcend.

Apple MacBook:

I really like the MacBook, although the case material is plastic and I've heard horrible things about the Nazi-esque factories where Apple assembles the iPods in China... of course that hasn't stopped thousands upon thousands of people from buying Apple products in the past. I bought my iPod used ;-)

The MacBook is good because it has a dual-core Intel chip running at 2GHz. The screen-size is also a modest 13", which makes for a very portable notebook computer. A few friends of mine have one of these babies, and I very rarely ever feel the machine get hot, and the fan is as quiet as a mouse. The MacBook has a very decent battery life and also has great power management.

Putting Gentoo Linux on a MacBook is also very possible, but can cause conflicts with the Mac OS X. What I would most likely do, is completely remove the Mac Hard disk, and add a Trancend SATA solid-state-disk of 32 GB in size instead. Then I would have the original Mac disk image available if I ever needed to use it and I could format the original magnetic SATA disk and use it externally. I think that I remember reading a rumor about Apple launching a product targeting at the Japanese market with an SDD and no optical drive. Hopefully that happens soon and they decide to expand to western markets as well.

Since I am attending a university in Germany, I would receive a 10% discount at the Apple.de Educational Store. The student discount in Germany is even more of a deal than that in Canada, after considering taxes.

[1] Some articles about environmentally friendly computing, going as far back as 1998:
Toshiba Satellite 2510, Asus U5, Wal-Mart & Toshiba, OLPC, Consumer Demands

[2] I claim prior art to some of these device specifications going back for several years if a patent lawsuit ever arises.

[3] In full awareness of the current anti-DRM movement, I still feel that artists should be able to protect their works in an open, but still technologically secure manner. My position on DRM is that publically free media should still function on a system that is DRM-compatible, as should DRM-impaired media.

[4] I am in no way knocking the OLPC project, and feel that it's a pioneering endeavor that all manufacturers should strive to match, in terms of energy efficiency. The plastic casing, on the other hand, is a bit of a minus.

Done Exams!

I've finished my exams for the 2007 summer semester here in Kiel. Both of them went pretty well. The first was Computer Vision II: Stochastic and Topological Approaches to Image Processing, and the second one was Neuroinformatik. CVII went pretty well, although I was a bit pissed about the last question. Neuro went better actually, although I like CV a bit more. CVII is actually a fairly hard course, not as hard as CVI, but still.

I had a beer, as per tradition, as soon as I got out of the last exam, and then on the walk home, the air smelled fresher, the sun felt brighter, all of the music on my iPod seemed to fit perfectly with everything - a good sign ;-) Actually, having the ability to take time and walk home was a big change all by itself ;-) Usually I have no time what so ever, and am racing to catch the next bus too hand something in, or meet up with my study groups.

I'm looking forward to coming home ____SO____ much!!!

Now I can focus on my work a bit more, and get a couple of big projects out of the way. I'm excited to actually be able to concentrate on one 'job' for the summer, getting new toys to play with (i.e. embedded devices), and doing some electrical design / hacking too! I'm also planning on hacking a couple of open source apps like Banshee, iPodLinux, and writing more interesting code for my various embedded devices.

Finally, I can design some image processing hardware too, once I learn about the PCI bus and interface with the new TS-7800 boards ;-) Since I tore apart my old crappy 1.3 megapixel digital camera, I'm also hoping to put linux on it.

As of next semester I'm going to be registered in the M.Sc. in Digital Communications, which is taught in english, as opposed to Informatik, which is taught in german. That should lighten my load considerably, but also provide the same type of challenges that I'm used to in areas such as DSP, communication theory, analog & digital circuit design, and so on.

Digital Communications is an engineering program, which I like better. Not to say that I didn't like all of the experiences I had in Informatik - Professor Sommer's lectures are exactly what I was looking for by travelling halfway across the world, and I can't even put a price on some of the things I learned studying with him. The things that I have yet to develop will likely be some of the most advanced in my life.

I've also learned some very interesting things in CV, Neuro, Numerische Math., and yes, even Mathematical Logic!! Unfortunately, I have to give up my office, which is a bummer, but the change to Digital Communication will surely have plenty of benefits to make up for it ;-)

The best and most important part everything now, though, is enjoying the summer!!! I'm really looking forward to meeting up with all of my friends in Canada, seeing all of my family, and of course Erin too :) woohoo!
