Google Open Source Jam and Webtuesday Hackday //at 21:01 //by abe

I was at two geek events in Zurich this week: At the Google Open Source Jam Zurich on Thursday evening and at the first Webtuesday Hackday on Saturday.

Somehow I expected both events to be quite similar, but they weren’t.

Google Open Source Jam

When I read “Jam” or “Jam Session” I think of Jazz musicians spontaneously playing together. So for me “Open Source Jam” sounded like a hack session where some spontaneous coding is done. But there was no spontaneous collaboration at Open Source Jam at all. It’s just (more or less spontaneous) talks about different topics and chatting. So I was quite disappointed from that event.

There were though quite a lot of people I knew from e.g. Webtuesday, Chaostreff or Debian. I even met some people I just knew from IRC until then.

Half of the talks were sole propaganda talks though, e.g. for Webtuesday Hackday, OpenExpo and Soaring as a geek sport. Not really wrongly placed talks, but not what I expected in talks at Open Source Jam.

The few rooms and floors I saw reminded me very much to IKEA Children’s Paradies, just even more motley. Though it felt all sterile and wasn’t by far as cool as I expected after what I read elsewhere of Google offices.

I also think that several of the Google employees showed some contrived friendlyness, and questions I asked e.g. why I have to give them my e-mail address and employer’s name (what do unemployed or self-employed people do?) got answered with answers I do not really believe – like “for security”. A leopard doesn’t change its spots. A data squid probably neither, even not at events labeled with OSS and said to be for the community.

I suspect that finding new employees is one of the reasons behind such events at Google. But after my first visit at one of their locations, this company still makes me feel uncomfortable. And I’m even more sure than before that I wouldn’t want to work there.

Not sure if I’ll attend the Google Open Source Jam a second time.

Webtuesday Hackday

Webtuesday Hackday also was not as I expected, but still more close to my expectations: the Webtuesday crowd gathers for hacking instead of having long talks. :-)

There were surprisingly many people from outside Zurich, from Munich and Belgium, from Lake Constance and Lausaunne – not only the usual suspects (who were there anyway ;-).

The event took place at Liip’s new office. They still look a little bit empty and steril, but all the toys (mini rugby balls, Wii, plush figures on floor lamps) and people around made them very alive. And they had very cool lamps in the form of their company logo in the office. They sure have a good interior designer. :-)

Although most participants found time to do some hacking, many found less time than they expected so we hope that we can glue the talks a little bit more together in regards of timing to cause less interruptions of the hacking.

The food was also better at Hackday, too, but mostly because we ate outside. ;-) For lunch we were at Lily’s Stomach Supply at Langstrasse (very recommendable!) and in 6he evening we were at Pizzeria Grottino 79 near Helvetiaplatz. Had a Pizza Vesuvio with Gruyère cheese there.

Hackday also had a surprise for me: The IRC channel at Hackday was but when I entered the channel there were someone in I didn’t expect there: tklauser aka Tobias Klauser aka tuxedo. Even more surprising, he read about my project idea for Hackday – a semantic feed cache proxy – and liked it, so he decided to come over to Zurich and join the project.

We didn’t came that far until Tobias had to leave again, but the progamming language and partially also libraries had been nailed: Ruby and it’s WEBrick framework. After the Hackday I worked on it a few more hours and it now already saves feeds to a cache. The Mercurial repository is at http://noone.org/hg/sfc-proxy.

There were several reasons which spoke for using Ruby instead of Perl (my favourite progamming language and the one I’m most experienced in): Ruby brings HTTP and RSS support already in it’s standard classes and Tobias is more experienced in Ruby than Perl. I started to learn Ruby a few years ago to look beyond my own nose and to get my hands dirty on some object-oriented and nice programming language, but I hadn’t found an appropriate project until now, so this was one more reason to not do it in Perl.

I also worked on my Debian package of Conkeror during Hackday. It’s already usable and I now use Conkeror as primary web browser on my EeePC, but e.g. the man page is still missing. As soon as I have the minimum in necessary documentation ready I’ll let it upload to Debian Experimental (since its dependency XULRunner 1.9 is also only in Debian Experimental yet). The Mercurial repository for the Debian packaging of Conkeror is at http://noone.org/hg/conkeror/debian

Those who were still at Hackday in the evening decided that the Webtuesday Hackday should become a regular institution and should take place approximately every two months, but stay a one day event (for now). I already look forward to the next Webtuesday Hackday.

Favourite Linux Desktop Applications //at 17:18 //by abe

foosel tagged me, whatever that means. Perhaps it’s the English word for “Stöckchen” (German for “small stick”) of which I always wondered how the English blogging part of the blogosphere is calling that kind of coercing blog posts… ;-)

So these are the rules:

1. blog a list with your favorite desktop Linux software (as many or few you want)
2. add links to the software project’s websites
3. post these rules
4. tag three other Linux using bloggers

Interestingly splitbrain, who started the thing just calls it “Meme”, but to me memes are the same thing just without duress. ;-)

So you want to know about what Linux desktop software I like and use, hmm? Desktop means GUI, doesn’t it? There are only a few GUI application I really use often since, as you probably know, X is primarily a terminal multiplexer and screen resolutions are compared by how many 80×25 xterms with fixed font you can get on one screen without overlapping. ;-)

But to be honest: Although I’m more the command line guy hacking cryptic lines into windows with small fonts, there are a few thing where I don’t want to miss X and the GUI applications: For all things web – that means web browser, feed reader, etc. But then there is also a bunch of GUI software I use occasionally or as alternative tool to some text mode or command line software.

Web

• Liferea – My favuorite feed reader although it takes ages to start and since a few days also starts crashing, probably since I have configured it to cache up to 1000 items per feed and have subscribed to several hundred feeds.

  I do not read them all though, but I use them togther with Liferea’s “search all feeds” feature as a Google News replacement. ;-) I though read a lot of feeds in it, since I use it for news, blogs, webcomics and to read missed tweets on Twitter. It organizes the feeds in a tree structure so I can easily group different types of content together.

• Opera – I’m back using Opera as my primary web browser since they offer alpha versions for 64-bit Linux.

  Initally I started using Opera with version 3.60 on Windows 95 somewhere about 10 years ago and I’ve always come back to it when no current free browser fits my needs.

  Although it hasn’t an AddOn possibility as Firefox has, I still prefer it over the bloaty and leaky and quite unstable Firefox 2, since it offers nearly every functionality I need (mainly mouse gestures and a flexible tab management), is fast, needs less RAM and is quite stable for an alpha version. And Firefox only offers those features I need via Addons which are often the cause for leaking or crashing. Haven’t tested Firefox 3 yet, but it’s said to be be less bloaty…

• Kazehakase – Formerly I used kazehakase as my primary web browser since I really like its user interface, but the version in Etch is quite slow and seems to have memory leaks. It’s currently the second browser I have always open. But since my browsers always have uptimes in terms of months I don’t need web browsers that are leaking, so I’m thinking about replacing it with something more stable.

• Conkeror – A Gecko 1.9 (i.e. Firefox 3) based web browser completely controllable with the keyboard. And the key bindings are those from Emacs and partially also from the classic text-mode browser Lynx. Will be available in Debian Experimental soon.

• Netsurf looks very promising as it’s a simple and fast browser with it’s own rendering engine and originating on RISC OS. But since I’m a heavy tab user (60 tabs in one window are not really seldom), a browser (yet) without tabs isn’t really that useful for me. But I hope it will get tabs soon.

• Midori – The other upcoming new browser in the Linux world is using Apple’s WebKit (which itself is based on KDE’s KHTML) underneath. Only in Experimental yet (form a Debian point of view :-). Use it on my Debian Sid machine to play around with it.

• Twitux – A simple GTK Twitter client which doesn’t clutter the screen with unnecessary icons or buttons. Just a small menu bar, status bar and the tweets.

• Azureus – In the seldom case where I need to download files via Bittorrent I either use Opera’s builtin client or Azureus. The nice thing about Azureus is that you can get nice graphical as well as textual statistics about all aspects of your downloads.

X / Desktop Environment

• FVWM – My favourite window manager for normal, big or multiple screens. I use it since more than 10 years (twm and tvtwm were its predecessors) and its configuration has evolved since then quite a bit to tinted transparent window frames and title bars, etc.

  I tried other window managers in between (e.g. Sawfish and GNOME’s own Metacity, each for a month or so and both together GNOME, also played around with KDE on one machine) and I always came back to FVWM. No other window manager is so fast and configurable in regards of keybindings. Handles multiple screen very well and out of the box, too.

• ratpoison – My favourite window manager for small screens (less than about 1024×768, e.g. on my EeePC, on the 8” touchscreen connected to my MicroClient Jr. or on my 1996 ThinkPad 760ED with 133 MHz Pentium 1) since it doesn’t waste screen space for window borders or title bars. It just maximizes all windows by default to screen resolution. You then can manage (split, resize, switch, close, kill) windows as you are used to manage shells and text-mode applications with screen(1). Doesn’t work that well with multiple xrandr managed screens though if they don’t have the same size.

• FLWM – The Fast and Light Window Manager. My favourite low-end but still DAU compatible window manager. Use that on demo and guest accounts, especially on low end machines.

• Synergy – connects displays of other computers (not only X but also even Mac or Windows) with your mouse and keyboard similar to a KVM switch. I use it at work to add my laptop as fourth monitor. ;-)

• trayer – A desktop environmen independend system tray developed by the FVWM Crystal Project. Since I changed from manually editing /etc/network/interface on my laptop each time I came into a new wireless LAN to using GNOME’s Network Manager, I needed a system tray for the nm-applet. Trayer is quite easy to configure using command line options and can handle tinted transparency as I use with FVWM and ATerms. So it fits in perfectly.

• ratmenu and dmenu – For showing generated menus together with ratpoison, I use ratmenu (e.g. as replacement for ratpoison’s non-interactive window list) and dmenu (e.g. as application menu using my own wrapper which generates the menu from some config file). Probably will publish that code once it proved itself stable.

• xtrlock – the simplest tool to lock you desktop: The mouse turns into a lock and it only goes away if you enter the right password. No screen saver included though and everyone can see what’s on your desk. I like it though. Use it on low-end machines.

XScreenSaver and Really Slick Screensavers (GLX Port) – Configurable and command controllable screen saver daemon. Favourite modes: GLMatrix and Substrate from XScreenSaver and Lattice Sky Rocket and Hufo’s Smoke from RSS GLX.

• xosview – my favourite system monitor since more than a decade.

Terminals

• xterm – there is no better X terminal emulator than the original xterm. I found no other terminal which is so fast, has no problems with text-mode applications (aterms break aptitude’s display), no problems with character set encodings, which can be embedded into other applications and which has a fully working classic Unix cut & paste.

• aterm – When I need a fancy transparent terminal for showing a fancy desktop, I use the AfterStep Terminal Emulator aterm. In that case, the system tray, the window borders, the window’s title bar and the terminal on my desktop have the same fancy tinted transparency.

• yeahconsole – A wrapper around xterm which works like the pulldown console in quake. Good for the short shell usage inbetween. ;-)

  The other similar pull down consoles I know (KDEish yakuake and GNOMEish tilda) had some issues with focus and keybindings while yeahconsole works just out of the box and showed no problems until now.

Audio and Video

• XMMS and Audacious – If I want to play a single list of files of the same file format or single stream, I usually use the command line tools mpg123 and ogg123. But if I need anything more fancy or more flexible, I prefer the WinAMP clones. Formerly XMMS, nowadays Audacious. Both with some old skin which I use since more than a decade and which I initially used with WinAMP 2 on Windows 95.

• mplayer – no fancy GUI, easily controllable with the keyboard, plays most video file formats I can remember. ;-)

Editing and Developing

• GNU Emacs – I’ve been raised with GNU Emacs and Lisp at university, so I’m quite sticked to that. I usually only start one Emacs instance and connect to it using emacsclient. I also like TRAMP for editing remote files. but I don’t need it that often.

  On machines, where I don’t want a full blown Emacs installation or under root I prefer GNU Emacs’ little brother GNU Zile (Zile Is a Lossy Emacs), but that’s text-mode and no GUI software.

• OpenOffice.org – I think it’s a really great software, but I use it quite seldom, usually only when I have to open some file in a Microsoft file format. For writing letters, articles, presentations and so I have LaTeX.

• Gnumeric – My preferred spreadsheet application. Although for some purposes I use the OpenOffice.org spreadsheet, usually when Gnumeric has not all necessary features.

Graphics

• xv – Yet another tool I use since more than a decade: No other image viewer is so fast and yet so easy to use with both keyboard and mouse. Open source, but unfortunately not (yet?) free software.

• keyjnote – fancy PDF presenter with a lot of interactive features.

• pdfcube – PDF presenter turning pages as a cube as compiz or Macs do with the desktop.

Chat

• Pidgin – I usually use irssi inside a screen for IRC as well as Jabber and ICQ (via Bitlbee), but I also often have a local Jabber client running which then is Pidgin (formerly known as GAIM).

Other Tools

• Unison – I use it to synchonise the cache and state of my feed reader between laptop and workstation. And I do indeed prefer the GUI version over the text-mode version. I use the text-mode only if I use it from some remote location.

• XKeyCaps – The ideal tool to wreck you keyboard layout. ;-)

• XGnokii – Used it to backup my former Nokia mobile phones, the 6130, the 6210i and the 6310i. Doesn’t work anymore with my new E51, though.

• Sunbird / Iceowl – Not really using it yet, but I plan to use it as my primary calendar tool.

• QEMU / KVM / KQEMU – My favourite desktop hardware emulator. (For servers, I prefer Xen for virtualization.)

Games

• ScummVM
• Planet Penguin Racer / Extreme Tux Racer (all forks of Tux Racer)
• Frozen Bubble
• Battle for Wesnoth
• cuyo, xpuyopuyo, flobopuyo
• Sauerbraten
• PrBoom / Freedoom
• Neverball / Neverputt
• Briquolo
• xfrisk
• Icebreaker
• XBomb

Non-Desktop Applications

In case someone wonders about my mail client, Jabber client, IRC client, ICQ client, file manager, notes taking application, shell and versioning system – they’re all command line or text-mode applications:

• E-Mail: mutt
• Chat, Instant Messaging: irssi + Bitlbee + GNU Screen
• File management: coreutils (and sometimes busybox ;-)
• Notes: hnb
• Shell: zsh
• Version control: Subversion (svn), Mercurial (hg)

Who’s next?

That’s difficult:

• maol would be interesting, but since a while he just blogs in Jeopardy style, so he would need pack all those programs into the subject of his blog post… No, not a good idea.
• Venty! No, has no active blog anymore.
• Dieter! No, no Linux user.

Hmmm, I think I have to look in a different corner of my circle of friends. Hmm. Ah, now I know:

• dyfa – not really a Linux user, but I guess FreeBSD is ok, too. :-)
• nion – this will be really interesting. He even uses more strange software than I do. ;-)
• alphascorpii – no idea what she prefers (except that it will be available as Debian package ;-)

And no, I don’t expect posts as comprehensive as mine. :-)

The mouseless side of X //at 00:48 //by abe

Although I like the idea of a tiling and completely keyboard focused window manager, I never fell in love with Ion because the default keybindings weren’t really intuïtive (to me). A few months ago I noticed, that ratpoison is also a tiling and completely keyboard focused window manager, only with much more intuitive usage: If you know screen and it’s keybindings, you also know ratpoison and it’s keybindings: Just exchange Ctrl-A with Ctrl-T. This sounds perfect for usage on my low performance laptops, where I have small screens and usually also no virtual desktops in use.

There’s only one thing which annoys me in ratpoison: If I use a mostly mouse driven application like e.g. a webbrowser with ratpoison, I have no problems to click on links, even if the webbrowser is not in the so called “current frame”. But if e.g. click into an input field, I usually notice much too late that while the mouse works fine in the browser, keyboard focus is still in some other window. Currently they all use flwm, the Fast and Lite Window Manager.

So what I would need is a tiling and keyboard focused window manager but with “focus follows mouse” politics. And since the laptops on which I intend to use such a window manager, all have a touchpad or thumbstick, the mouse there counts as keyboard focused, too somehow, doesn’t it? :-) I wonder, if an ion3 could be configured to use the same keybindings as ratpoison. That would probably fulfil this desire.

On the other hand, there are browsers which are fine without mouse. lynx or links2 for example, so the focus problem I have with ratpoison wouldn’t occur. But what if I need or want a keyboard driven and full blown webbrowser? Ok, Firefox as well as Opera are not that bad in keyboard only use, but they still are focused on the mouse using user.

But Gecko wouldn’t be Gecko, if there wasn’t some Gecko based browser with this features: On the ratpoison website I found a link to a very interesting Firefox plugin which makes Firefox a complete new browser, a keyboard driven webbrowser named Conkeror. It has no toolbars at all, no (visible) tabs, no menus, no nothing — it shows only the website in fullscreen, a status line and a multipurpose command line — exactly like the mini-buffer of GNU Emacs.

But not only the layout, even the keybindings are very emacsish: C-x C-f opens an URL in a new buffer -eh- tab, C-x 5 C-f opens an URL in a new frame (window), C-x C-v opens a new URL in the current tab (buffer) with the current URL as editable default value, C-x b switches to another tab, C-x k kills -eh- closes a tab, C-x C-b lists all open tabs, l goes back (remember the Emacs info reader, eh?), C-g quits accidently requested dialogs or stops loading a web page, Ctrl-s and Ctrl-r give you forward and backward i-search, C-n, C-p, C-f and C-b scroll, etc. Even M-x works, e.g. will M-x revert-buffer reload the web page. (Unfortunately Esc-x doesn’t work. Yet.) And for vi freaks, there is even M-x use-vi-keys. There’s even one lynxish keybinding: \ lets you view the source.

And although it’s one of the strangest webbrowsers I saw yet, I somehow like it and also would like to see it in Debian as package, since it is the perfect companion for ion or ratpoison. Looking through apt’s package cache as well as the wnpp bugs, I haven’t found any hint on somebody already packaging it, so I’ll have a look on it and on how to to package a Firefox extension for Debian.

BTW: While looking through the wnpp bugs, I found bug #335459, which is the ITP flock, an also Gecko based browser with a lot of cool features for blogger who like social network tools.

Another nice thing I found today in Debian was the xfonts-artwiz package whose small fonts are very suitable for small resolution screens, especially if a tiling window manager is used with a e.g. 800×600 resolution. Unfortunately they aren’t available in a charset with German umlauts.

Apropos tiling window managers: Anyone tried pconsole with an automatically tiling and resizing window manager? I wonder if it’s usable. At least on MacOS X with its cascading window positioning algorithm, pconsole is a pain. — But even without cascading windows, MacOS X is a pain for keyboard users. Just think of its default behaviour when using the tab key inside a form mask: It will skip all buttons, all checkboxes, all radio buttons and all select boxes. Argh!

wApua now in Debian Unstable //at 00:38 //by abe

Hey, the actual version 0.06 of my Perl written WAP browser wApua now is in Debian Sid!

It’s the first software written by me which has entered the Debian repository as its own package (since pum is included in the package pisg which is in testing now for a while) as well as the first software debianized by me which reached Debian Unstable.

Things are always exciting when they happen the first time. ;-)

Thanks to Myon for sponsoring the package.

wApua 0.06 released //at 03:33 //by abe

I today released version 0.06 of my WAP browser wApua (Release announcement at Freshmeat).

The one big new thing is user friendly documentation: wApua and wbmp2xbm (which has been renamed from wbmp2xbm.pl) now have POD documentation and therefore also man pages. Besides that a lot of minor bugfixes and enhancements complete the new version.

The other big new thing is that there now is a Debian package of wApua. The package should work fine on Debian Woody (3.0), Sarge (3.1) and Etch (upcoming 4.0) and probably also works on other Debian-based distributions like Ubuntu.

Thanks to sponsoring by Christoph “Myon” Berg the Debian package is also in the Debian New Queue and hopefully will be included in Debian Etch.

WML builds and runs on cygwin //at 01:26 //by abe

For a long time the Website Meta Language (WML) did not build on cygwin, but nobody knew why or how to fix it. At the end of last year, the WML maintainer changed to Shlomi Fish and one of his goals was to get WML run under cygwin.

Many probably didn’t expect it to really happen since WML developement has stalled for the last three or four years, but the Subversion 2.0.x maintenance branch of WML now builds and works on Windows under cygwin. This shows that there is really something going on in the WML developement again.

Congrats and thanks to Shlomi!

New talk proposal, new Linux distribution found //at 01:47 //by abe

After talking with some LinuxTag guys about which kind of talks are still missing for the upcoming LinuxTag, I submitted another proposal for a still only roughly sketched talk: KISS – Keep it simple and stupid, also on the web.

KISS – “Keep it simple and stupid” is an old and successful principle in the Unix world: Small and simple programs, doing only one thing, but they’re doing perfect, fast and reliable. This principle can also work on the web and make webservers or surf terminals out of already discharged computers.

I planned to show “simple” (or at least “simple to use”) tools like Blosxom or the Website Meta Language, a more slim webserver than Apache (e.g. fefe’s fnord or one of the ACME webservers thttpd, mini_httpd or micro_httpd), slim web-browsers (e.g. like Dillo, Opera, glinks, ViewML or Minimo) and one or more Linux distributions optimized for low end PCs. While thinking about low end PCs, usually the following distributions come to my mind: DeLi Linux, fli4l and Debian Woody.

But none of them seems to fit for my talk as perfectly as I would like:

• DeLi Linux is no bad distribution, since it’s designed especially for 386 to Pentium I, but I have some strong disagreements with the maintainer of DeLi Linux, since he sees a very small package list as necessary requirement for a distribution for old PCs. He states that distributions for old PCs “don’t have that many harddisk space” (beyond other, more realistic arguments — but it seemed to be his main argument) while I see a rich package diversity as an quality criteria. (One of the reasons, why I like Debian and dislike Ubuntu.) So I’m not sure if I should present a very raped DeLi Linux to the audience, just to make it fit my needs, although I’m quite curious about his upcoming 0.7 release with the low end, KHTML based ViewML webbrowser. (Apart from me seeing PHP5 and KDE as a big nono on old PCs…)
• Although I still like Debian Woody very much (you know that old story… ;-), it is just too old for making a talk about how to turn old PCs into being usable again. Sarge would be fine, but it was suggested to showcase an easy and fast way to get something ready to run, and I can’t give the auditors a list of all the Debian packages with low resource consumption and therefore usable on low end PCs.
• I haven’t used it yet, but fli4l seems to be very good distribution to turn an old PC into a ISDN or DSL router, even without harddisk. The last time I had a look at fli4l, it used an Apache as (optional) webserver, which wouldn’t fit into my scheme, since I would like to show an alternative to Apache. But as I found out today the recently released version 3.0 of fli4l uses the already mentioned ACME mini_httpd. Cool! They’re on the right way! ;-) Unfortunately it only seems to be used for serving information pages about the fli4l status and not as common webserver. (Please correct me, if this is wrong! I would appreciate it, if I’m wrong at this point. :-)

Since I first read about viewml on the DeLi Linux page, I looked for Debian packages of viewml today. apt-cache search hasn’t found anything on Woody or Sarge and packages.debian.org is still down, so I used Google. I found out,  that there at least was a viewml package in Debian since at least 2001, so I expect, it just didn’t make it to stable.

But I also found this interesting page on a webserver called www.ubuntulite.org. Ubuntu Lite? That sounds very interesting, since I see Ubuntu not as the baddest idea (expect for it’s horribly resource hunger and only offering one package per application by default ;-), but having an Ubuntu derivative prepackaged for low end PCs and with several webbrowsers instead of only Epiphany (and probably Firefox, don’t they?) would be perfect for my purpose.

So I’m currently downloading an Ubuntu Lite ISO and will give it a try on one of my Pentium MMX boxes. Unfortunately it doesn’t seem to support Pentium I or AMD K5 since Ubuntu itself only supports i686 and upwards. :-/

But this also means, that it’s no occasion for my Pentium I Compaq LTE 5100 (which I probably will name pony), but currently, after Bartosz’ recent post on Planet Debian, it looks like Debian GNU/kFreeBSD could also be an interesting OS, since it fits all requirements perfectly: Free, Modern, Exotic and all conveniences of Debian. ;-)
