This is the first post about my progress on GSoC'09 for Gentoo. Also, disclaimer: I'm tired (07:08 here), think for yourself :-) As a "side product" of my earlier Gentoo GSoC'09 activities a hopefully complete TurboGears 2.x stack has grown in my "sping" overlay. I can understand now why the Python herd has not packaged TG 2.x before:
- The unpackaged portion of dependency tree is quite large (see here: dev-python and net-zope)
- Many people probably run TurboGears in a virtual env and don't install it system-wide
- g-pypi is a huge help but no way near auto-pilot
(Talking of g-pypi: an update to
app-portage/g-pypi-9999 (sping overlay)
brings post-0.2.1 bugfixes!) To check out the current state of TG2 this is
what you might want to do:
sudo layman -a sping sudo layman -a python-testing sudo autounmask dev-python/turbogears-meta-2.0 sudo emerge -av dev-python/turbogears-meta
If all goes well that meta package enables you to create and run the quickstart app right away. But: With so many packages involved something more or less has to be broken for you. Please contact me about it, I'll be happy to fix what's needed or pull from you.
This release adapts to the lowpass range extension introduced with libbs2b 3.1.0. So if you (or someone else) upgrades libbs2b on your machine to 3.1.0 you should upgrade to 0.9.1 of the LADSPA plugin. Get it here:
Let me take the opportunity to point to

libbs2b 3.1.0 is out, get it here:
And the change log:
bs2bstream— add switch of crossfeed level by feed level and cut frequency.
- Win32 library of libsndfile v1.0.19 migrated to v1.0.20.
- Fixed for higher compile warning level.

Writing about this seems to be sticked to my mental todo list. So I'm writing about it now to better concentrate on other stuff after. Let's see if that works. When I buy stuff I end up at Amazon.de quite often. With the order flyers for special offers from partners of Amazon are shipped. VistaPrint flyers were among these several times. A need for business cards first hit me on 25c3, when people I was talking with gave me their cards while I had to give "sorry, I don't have any" back. I guess about the third time it started annoying me. When I first came to the VistaPrint site the what-you-can-pay-with FAQ entry did not list any non- credit-card means to pay. As that is not acceptable to me I wrote a mail, got no answer, but PayPal magically appeared in the listing. So that's my first "contact" to the VistaPrint support. A VistaPrint order can be summarized like this (hint: look at line 4):
- Browse through designs you like and decide for one of them
- Interactively fill your card with data
- Decide about extra costs for a non-white back of the card
- Confirm that you're aware that you cannot change that design later (Do screenshots at that stage!)
- Register a user account
- Decide for more expensive paper or not (default, glossy, extra-weight)
- Decide for non-turtle-speed delivery or not (cheapest can take 21 days)
- Click through repeated special discount spam both inhouse as well as 3rd party
- Save a web page as confirmation
The whole process was somewhere between okayish to annoying:
- I either felt bad to spend more money than I wanted or to miss extra quality
- The interactive did a few strange things, e.g. font sizes decrease when I put round parentheses in and increase back when they're gone
- All the special offer crap made a really unprofessional impression to me
- The website has visible bugs, e.g. The offered address stickers showed "Address line 1" because I left that empty
To visualize the latter: do I want address labels like this?
(Ignore that it's black and white only. The customer contract with VistaPrint does not allow me to put the original designs/images here.) When the order was done I had a look at the order's summary and the related preview images showing my future business cards. That's when I noticed that something was broken: the font size of my website and e-mail address had strongly decreased. This is before and after reduced to just the font size issue:
So I was worried that my internet contact info would actually look as small as that, so I contacted support through mail with two images attached elaborating on my worries. The screenshot came in quite handy here. The usual machine generated thanks-for-your-mail stuff came in, no real reply. If they had read that mail, they would have saved sending out broken cards the first time. A few days later I wrote another mail ~"hey guys, I think it's quite poor that you don't handle my case at all". No reply either. When the cards arrived the font was as small as I was afraid it would be. So I called support this time: ~"Great I get through to somebody, you've been ignoring my mails three times now". I described what I had done: that I had confirmed the sane version, not the broken one, that I made a screenshot, that it did not fake the screenshot and that it would be hard to do. The lady on the line tried to reproduce my problem and it turned out I was right: the system actually had a bug. Oh really. 9 million customers and noone ever hit that. (Sometimes they say 16 million, I guess both are fake.) She offered to come back to me the other day. It took her another day but what she had initiated by then was fixed cards with express delivery (7 days) all for free. I'm thankful to hear for that. I have no idea if these these bugs have been fixed: I asked but have not reaceived a reply yet.
pcmanfm 0.5.1 is both a bugfix and a feature release. The purpose of this blog post is to pick out the gems why you really want to upgrade. If you have just a few seconds a minimal summary would be, that you should upgrade for:
- fixes to critical bugs
- better keyboard support
- GUI customization
In more detail this is what is worth mentioning to me the most:
- Fixed: copy-paste-rename-escape-truncate bug (#2710035)
- Fixed: Running "pcmanfm foo" now opens directory
$HOME/foo before) (#2715642)
- Added: GUI options to ..
- display file sizes in kilobyte or kibibyte (#2250721)
- show/hide location bar
- show/hide side pane buttons
- show/hide tab bar even when there's just a single tab
- show/hide tab close buttons
- Added: Keyboard support extended:
- Tree navigation through
and (#2040282) now works like (unassigned before) toggles pane to location pane toggles pane to directory pane and cycle through tabs (#1570102) and cycle through tabs (#2328418) shows jump-to-folder dialog when location bar is hidden
- Tree navigation through
To me this means I can use copy-paste with less worries than in 0.5 and strip down the GUI what I really want to see. In 0.5 you get this view, no matter what:
Below is what I use now, most importantly without these side pane buttons that I came to really hate to have to look at.
Thanks to Eugene Arshinov for making that pain optional (and for most of the other GUI improvements). If you're running Gentoo: The sping overlay has a bumped ebuild already.
Three WTFs about LADSPA:
- When writing a LADSPA plugin you need to request a globally unique ID for that plugin. Without such an ID you basically cannot release your plugin to the public. LADSPA hosts actually use that ID to identify plugins so collisions are a real problem.
- Range control slots (think sliders from say 0 to 100) can have a default value out of a predefined set only: You can set it to things like 0, 1 or its mean but not 600 if you wanted to. I did.
- When compiling the latest LADSPA SDK (v1.13) with plain
makealso a test suite is run that plays back white noise through your real sound hardware. That's not only unexpected for a run of
make(what do we have make check for?), it's plain "fun" if you have headphones on at that moment.
New releases ready for you:
- XMMS bs2b plugin 0.5.0
- All stream formats are handled now
- Audacious bs2b plugin 0.9.2
- Sample rate change propagation fixed

Asian symbol pieces can make entering Chinise Chess (Xiangqi) unnecessarily difficult for non-asian people. To ease things up a bit using "western" pieces can help, especially as most pieces have (close) equivalents in regular chess. In contrast to a hardware game , in software changing pieces can be an easy thing. The small script I made downloads piece graphics from chessvariants.org and makes them usable for hoxchess, a Free Software Xiangqi program. Here's a picture of what that can look like:
Once you want to start playing with the original pieces the following set might be an option. The script also grabs that; it's taken from the game at pragmaticlogic.com.
I'm still at learning the rules btw in case the post suggested something else before. Download
Just a quick post about something that I hope to turn out as lots of Gentoo fun: I've been accepted as a Google Summer of Code 2009 student for a project of Gentoo. Its title is "Create and release a Gentoo stats server/client". I'll be extending Fedora's Smolt to more or less bring a popcon-clone to Gentoo. Stay tuned.
