Chemnitzer Linux-Tage 2010 is almost here, and Gentoo will be there!

This years Chemnitzer Linux-Tage on March 13th and 14th is another great chance to:

• get in touch with Gentoo developers
• buy Gentoo shirts (be quick, first come first serve)
• chat, discuss, start with ebuilds and overlays, you name it

The "Chemnitz Linux Days" is a conference that deals with Linux and Open Source Software . It is open for everyone, novices and experts alike. This event is organized by IN Chemnitz, CLUG, Computing Center and Faculty of Computer Science of Chemnitz University of Technology, and many volunteers.

See you there!

SCALE 8x is almost here, and Gentoo will be there!

Southern California's premier open-source software event is just around the corner, running from Friday, February 19 through Sunday, February 21. Several Gentoo developers will be there; it will be our biggest showing since SCALE 5x.

We'll be showing off some nifty devices running Gentoo, and we'll be giving out installation media. Whether you're a developer, user, or simply curious, be sure and stop by booth #33. See you there!

Gentoo has turned up in lots of interesting places before, but Michael from Misa Digital has put Gentoo to work in something entirely different: a unique instrument he invented, a MIDI guitar that uses a touchpad and digital keys instead of strings!

Behold the Misa Digital Guitar:

The Misa runs Gentoo Linux on an AMD Geode processor, using the Linux kernel version 2.6.31. It sports MIDI and Ethernet ports for connectivity.

I had the chance to ask Michael some questions about the guitar and his preferred choice of operating system:

Why Gentoo?

Since the guitar is an embedded system, I needed a really minimal distribution that would boot fast and had a small footprint. After investigating Linux From Scratch, I realised I did not have the time to invest in building a complete system. I was told that the minimal install of Gentoo is like Linux From Scratch with a package manager. I probably made you cringe with that simplistic analogy but essentially it was right for me. Once I had the install up it took me no time to recompile the kernel and streamline it as much as possible. I'm not a Linux expert though, so I reckon someone else could shrink it even more.

Yes, there are other solutions out there but they are surprisingly inaccessable. And the "live-CD" style distributions do not allow you to change the actual workings of the system. I figured it was best if I just used Gentoo because I have full control.

What were the two biggest challenges in crafting this instrument?

I would say the two biggest challenges are: 1) manufacturing and tooling the actual parts; and 2) sourcing components.

When you are a lone developer with no company, trying to keep the idea "secret", no one wants to cooperate with you. For example if you need a particular electrical like a screen, ordering "one" of something is surprisingly difficult - and you can expect it in 4 to 6 weeks - really slow! And then when you get it, you realise it is not suitable, so you have to repeat the process. The only exception is a website called Digikey, which will have the parts at my doorstep in 1 week guaranteed. But they don't have everything.

Working with Gentoo was a breeze, the Linux community in general is extremely helpful.

What can you tell us about the hardware?

There is no signal processing, it outputs digital signals via a MIDI connection. I had toyed with having an onboard sound generator but ultimately you limit the sound possibilities. By using MIDI, you are guaranteed support with practically every sequencer, synthesizer etc on the market - it is a standard that has been around for over 20 years.

[The touchpad] is a 5 wire resistive touch sensor. These are the most durable screens available on the market. The LCD behind it is OEM and ordered from China.

What changes to Gentoo (as a distribution) would make it easier for you to run it on the guitar?

I thought Gentoo was a breeze to work with. And can I just say, the Gentoo x86 install handbook? BRILLIANT. I used it so much that I think I actually know it off by heart now.

What's in store for the future?

I'd just like to see these instruments hit TV :)

Thanks for your time, Michael, and for crafting such a unique instrument! Be sure to watch a demonstration video of the Misa Guitar in action.

A parting gift for the German Conspiracy,

Gunnar Wrobel recently acquired the rights for his own book about Gentoo, and it has now been published under a free license and is available for download. The latex source for the book is also included. Gunnar's intentions in publishing the latex source was to encourage translations... it would be neat if that really happens. Please take the time to thank Gunnar for all the excellent work he has done for Gentoo.

Yes, we will be there! Compiling all the way ... ,

Gentoo will be present at the 26th Chaos Communication Congress (26C3), from December 27th to 30th in Berlin, Germany. The annual conference of the Chaos Computer Club takes place at the Berliner Congress Center (bcc) in Berlin, Germany. Enjoy our ebuild hacking sessions, bug filing workshops, get some merchandise and use our local rsync/http mirror. You will find the Gentoo table on the upper floor.

Hope to see you there!

The Gentoo Foundation Inc. has been approached by a few large Gentoo users about purchasing advertising on the gentoo.org side bar. They are not in the IT industry so cannot support us in the traditional way, by donating their own product.

The trustees anticipate that more approaches of this nature will be received and view it as a sign of Gentoo maturing. Recognising that this would be a break with tradition, by allowing even major users to contribute to Gentoo in this way the trustees determined to put the question to a vote of Foundation members.

The recording date for the vote will be 29th November. Voting will be from 1 December to 11 December, to enable the result to be available for the next Trustee meeting on 13 December.

Important: To vote, your Foundation membership must be approved on or before that date.

Requirements:

Please refer to the Gentoo Foundation Bylaws, in particular 4. Article IV Members

The motion to be voted on will be:

Should major Gentoo users be permitted to purchase ads on the sidebar - Vote yes or No

If you have any questions please contact Trustees or on irc at #gentoo-trustees.

Please turn your KDE radio on, and make sure to increase the volume to its maximum level for this important message.

After multiple setbacks we have finally managed to stabilise KDE4 on both major desktop architectures (amd64 and x86), with other teams to follow.

For this and other reasons as discussed , those of you who still use KDE3 should be seriously considering an upgrade in the near future.

The KDE3 support is being deprecated with immediate effect. This means that ebuilds are dropping KDE3 support where they were broken, or clashing with KDE4.

If you wish to still use KDE3, and you want to help others with having KDE3 around, drop a mail to kde@gentoo.org, where we can give you commit access to the special overlay which will specifically contain only KDE3 packages.

This overlay (named kde-sunset) can be easily used via layman.

Sadly upstream is not supporting KDE3 anymore and we simply lack the manpower to keep support for both (as you might have noticed in the past few months KDE3 has become more and more rusty for which we humbly apologize).

Sorry to bring you the bad news and with hope that KDE4 will suit your needs,

The Lost Knowledge column explores the possible technology of the future in the forgotten ideas of the past (and those just slightly off to the side). Every other Wednesday, we look at retro-tech, "lost" technology, and the make-do, improvised "street tech" of village artisans and tradespeople from around the globe. "Lost Knowledge" was also the theme of MAKE Volume 17

Ever since we humans started making shadow puppets in the firelight of our caves, we've been fascinated by the power of the projected image. It seems only fitting that, for DIY Movie Making Month, we'd take a look at magic lanterns, some of our first technological baby steps that have delivered us to the age of Avatar.

What is a magic lantern? It's basically a 17th century pre-cursor to the slide, and then movie, projector. The Magic Lantern Society defines a magic lantern as:

Magic lanterns grew on the developments of magic shadow shows (i.e. shadow puppets), camera obscura, magic mirrors, and other earlier optics and projection techniques. The period of the magic lantern spanned from the mid-17th century to the late 19th. While there is no clear inventor of the device, Dutch astronomer, mathematician, and physicist, Christiaan Huygens (1629-1695), with his lenses designed for use in telescopes, is probably the closest thing to a father of the technology.

Back in 2003, Songdog alerted me to a pair of synonyms, gennel and snicket (and the resulting post sparked off almost three years' worth of enjoyable discussion); now he draws my attention to an interesting column by lexicographer Erin McKean (discussed many times on LH, e.g. here and here) about synonyms:Distinguishing between close synonyms (is the ground marshy or boggy?) is a point of pride for the word-minded, and being able to argue whether someone was nonchalant or blasé is a pleasurable parlor game, made all the more fun by there being no ?right? answer. We may not agree as to the exact shade of difference, but we?re sure there is one.

Our desire for each different word to have its own meaning has deep roots. When children first learn language, one of the tenets of the language-acquisition process is a learning strategy called the ?principle of contrast,? which posits that two words should never have the same meaning - and if they do, there?s something wrong with one of them. Children internalize this principle and eventually, with enough reinforcement, replace nonstandard forms with the correct ones. When a child says, ?I did that goodly,? an adult will usually respond, ?Yes, you did that well!?, and well eventually bumps goodly from its slot in the child?s vocabulary.All well and good, but she goes on to discuss a phenomenon I find bizarre, the attempt to find semantic distinctions between spelling variants:

For portable radio operation, I like End-Fed Half-Wavelength Antennas (EFHWA, pronounced "EF-WAH"). This type of antenna is similar to the common half-wavelength dipole, but with one significant advantage. A dipole has its feedpoint (where it connects to the radio) in the middle of the antenna, but an EFHWA's feedpoint is at one end. This makes it very convenient to throw the antenna up in a tree and connect the bottom of it to your radio. Here are instructions for making a multiband end-fed half-wavelength antenna that works on 17, 20, 30, and 40-meter bands.
