Blogging is futile

Dear Aunt Google,

… this is “Do no evil”—urchin.js isn’t.

For luck, urchin.js and friends can be easily blocked using e.g. Firefox plugins like AdBlocker or NoScript, or with filtering proxies like Privoxy. And a line like

address=/google-analytics.com/0.0.0.0

in the dnsmasq.conf of your home router works like a charm, too.

Blosxom 2.1.0 released

abe+blog@deuxchevaux.org (Axel Beckert) — Wed, 23 Jul 2008 02:01:43 +0200

Today I had the honour to prepare and announce the first Blosxom release after exactly two years and six days.

The primary cause for the Blosxom 2.1.0 release date this week was to get our development efforts of the last two year into Debian Lenny with a nice version number (i.e. one without snapshot dates in the package version ;-). The second biggest cause was that it just was time. But Debian Freezes always give you a good kick in the ass. ;-)

Rhonda plans to prepare an updated blosxom package for Debian during the day. (Update 25-Jul-2008: Packages are available.) So if Planet Debian is broken in a few days, you know whom to blame: Me and my last minute bug fixes. ;-)

But since you seem to be able to read this, the release shouldn’t be too broken – because of course my blog already runs the very fresh Blosxom 2.1.0 release. ;-)

Conkeror in the Debian NEW queue

abe+blog@deuxchevaux.org (Axel Beckert) — Tue, 01 Jul 2008 21:39:11 +0200

I already mentioned a few times in the blog that I’m working on a Debian package of the Conkeror web browser. And now, after a lot of fine-tuning (and I still further new ideas how to improve the package ;-) Conkeror is finally in the NEW queue and hopefully will hit unstable in a few days. (Update Thursday, 03-Jul-2008, 18:13 CEST: The package has been accepted by Jörg and should be included on most architectures in tonight’s updates.)

Those who could hardly await it can fetch Conkeror .debs from http://noone.org/debian/. The conkeror package itself is a non-architecture specific package (but needs xulrunner-1.9 to be available), and its small C-written helper program spawn-process-helper is available as package conkeror-spawn-process-helper for i386, amd64, sparc, alpha, powerpc, kfreebsd-i386 and kfreebsd-amd64. There are no backported packages for Etch available, though, since I don’t know of anyone yet, who has successfully backported xulrunner-1.9 to Etch.

Interestingly the interest in Conkeror seems to have risen in the Debian community independently of its Debian packaging. Luca Capello, who sponsored the upload of my Conkeror package, pointed me to two blog post on Planet Debian, written by people being fed up with Firefox 3 already and are looking for a more lean, but still Gecko based web browser: Decklin Foster is fed up with Firefox’ -eh- Iceweasel’s arrogance and MJ Ray is fed up with Firefox 3 and its SSL problems.

Since my previously favourited Gecko based web browser Kazehakase never became really stable but instead became slow and leaking memory (and therefore not much better than Firefox 2), I can imagine that it’s no more an candidate for people seaking for a lean and fast web browser.

Conkeror has some “strange” concepts of which the primary one is that it looks and feels like Emacs:

The current location is shown in a status bar below the website, where Emacs usually shows buffer names. All input, even entering new URLs to go to, is done via the mini-buffer, an input line below the status bar.
Instead of tabs it uses Emacs’ concept of buffers. So no tab bar clutter and though easy access to all currently open pages.
It has no buttons, menu-bar or such. And except the status bar and mini-buffer, it uses the whole size of the window for the displayed web page. This is the main reason why I prefer Conkeror on the 7” EeePC: I don’t want to waste any pixels for buttons or menu bars and still have a fully functional web browser.
It of course has Emacs alike keybindings (with a slight touch of Lynx). While this may seem awkward for the vi world (Hey, they have the vimperator^*, also in Debian since a few days!), as an Emacs user you just have to remember that you web browser now also expects to be treated like an Emacs. It just works:

C-x C-c
Exit Emacs -eh- Conkeror

C-x C-f
Open File -eh- web page in new buffer

C-x C-b
Change to some other tab -eh- buffer

C-x C-v
Replace web page in this buffer and use the current URL as start for entering the new one

C-x 5 2
Open new frame -eh- window

C-x 5 0
Close current frame -eh- window

C-x k
Close tab, -eh- kill buffer

C-h i
Documentation

C-s
Incremental search forward

C-r
Incremental search backward

C-g
Stop

l
Go back (Think info-mode)

g
Go to (Open web page in this buffer)

(Hehe, I like the faces of vi users having read these keybindings and now wondering how to remember them. SCNR. Well, sometimes vi key bindings are a mystery to me, too. :-)
There are of course many more and nearly all are the same as in Emacs, even the universal argument C-u and the M-x command-line are there. E.g. C-u g lets you open a web page in a new buffer, too.
Conkeror also has very promising concept for following and copying links with the keyboard only. Opera is very inefficient here since you have to jump from link to link to get to the one you want. In Conkeror you just press f for following or c for copying links and then all links on the currently shown part of the page show a small number attached to it. Then you just enter the number (and additionally press enter if the number is ambigous) and the link is either opened or copied to the clipboard.
A funny anecdote about how this concept grew over the time: Early versions of Conkeror (back in the days when it just was a Firefox externsion as vimperator) numbered all links on the page, not only the visible ones. On large pages with many links or buttons (e.g. my blog ;-), this took minutes to complete. The idea to just number the visible links is so simple and important – but someone first needed to have it. :-)

Footnotes

*) I just noticed that there is now also muttator, making Thunderbird look and behave like vim (and probably also mutt), too. Wonder into which e-mail client the Emacs community will convert Thunderbird. GNUS? RMAIL? VM? Wanderslust? What will it be called? Wunderbird? Thunderslust? (SCNRE ;-)

Bath Tub, Rubber Keyboard, Ratpoison and Opera

abe+blog@deuxchevaux.org (Axel Beckert) — Sun, 08 Jun 2008 22:23:57 +0200

I recently noticed that a very good way to safely read webcomics in the bath tub is an old laptop with a big screen (e.g. a IBM ThinkPad A-series like my 15” A31 which has a nice 1400×1050 resolution), a water proof keyboard, the screen-alike, keyboard only driven (hence the name) window manager ratpoison (other keyboard driven window managers like wmii or awesome probably will do as well as ratpoison) and a good keyboard driven web browser which can bind or by default has bound a key to follow <link rel="next" ... /> tags.

Like Opera. Opera has bound the space bar to scroll one page down and if you reach the bottom of the page to go to the next page as labeled in the link tag. Additionally the full screen mode is helpful, too.

Or the dream browser of all Emacs addicts, Conkeror, which has bound the function browser-follow-next to ]]. (Conkeror packages will hit Debian Experimental quite soon.)

Or the GNOME feed reader Liferea which has bound Ctrl-Space by default to scroll down the content by one page and if you reach the bottom of the content go to the next unread item.

With that equipment I can read my favourite web comics like Questionable Content (whose content seldomly is questionable :-) or Ozy and Millie (Think of a mixture of Calvin & Hobbes, Peanuts and Kevin & Kell) in the bath tub without drying my hands before reading the next comic or fearing water or health damage by the combination of water and computer. I just press one or two keys on the keyboard floating over my lap and have a good time.

BTW: I’ve got a blue, non-branded one (packaging reveals it as “AirTouch Keyboard”, probably manufactured by SanChuan Electronics, China) with swiss-german layout from ARP Datacom (whose website offers no permanent links and insists on session cookies *puke*), but those from Keysonic or from ROCK seem to be very similar — nowadays they are also available in illuminated, miscellaneous colors and wireless, but only IP65, probably because of the necessarily accessible battery compartment.

But this kind of having fun still has optimisation potential: non-flexibel water-proof keyboard (IP67 recommended, so those IP66 keyboards and mice recently posted at UF LOTD are probably not tight enough), flat screen mounted above the bath tub, etc. ;-) Or maybe a completely water proof laptop if such thing exists — Does it?

One more note: In Debian Sid and Lenny recently a new tool called keynav has been added, which allows you to control the mouse quickly using the keyboard only. So with Sid or Lenny, I don’t even need an waterproof mouse or trackball if an application insists on mouse usage. ;-)

How to get Network Manager working with ratpoison

abe+blog@deuxchevaux.org (Axel Beckert) — Mon, 02 Jun 2008 00:59:34 +0200

Using GNOME Network Manager is a neat way to connect to wireless or virtual private networks from a laptop running Debian Lenny, Sid, Etch with Backports or any of the *buntu distributions. You can control everything from the system tray. But not all window managers have a system tray. And with some window managers it’s not obvious how to make them work with one of those lean third party trays and panels.

Especially my favourite window manager for small displays as on the EeePC – ratpoison – insolently puts any panel or tray in the middle of the screen by default. It took me a moment to find out how to make ratpoison work with my favourite third party system tray trayer (which can handle transparency and is only a system tray, no taskbar).

First we need to make ratpoison ignore the trayer on the one hand and and reserve space for it on the screen. Fiddling around with preconfigured frames didn’t work well and the following way is also more straight forward:

trayer always has “panel” as window title, so adding the following line to your .ratpoisonrc makes ratpoison ignore trayer:
```
unmanage panel
```
Now all windows overlap the trayer, so we need to configure the space for it. Trayer in the default configuration shows up at the bottom and has a height of 26 pixels, so we tell ratpoison to add a padding of 26 pixels at the bottom of the screen by adding the following line to the .ratpoisonrc:
```
set padding 0 0 0 26
```

Now we are confronted with the problem that these settings only apply to new windows, not ones which were already running when ratpoison starts. I usually start my X session using an .xinitrc or an .Xsession which calls the window manager using exec at the end.

We can start the trayer later though by spawning a subshell in the background with a sleep at the beginning. Also the Network Manager applet (nm-applet) can be started that way. In my case the end of the .Xsession looks like this:

( sleep 1; \
  trayer --align right --edge bottom --distance 0 \
	 --expand true \
	 --transparent true --alpha 128 --tint 0 \
	 --SetDockType true --SetPartialStrut true & 
  nm-applet & ) &

exec ratpoison

The result could look like this:

The other programs in the system tray are from right to left: nm-applet (GNOME Network Manager), Twitux (GTK Twitter Client), Audacious, Opera, Pidgin (formerly known as GAIM), Icedove (unbranded Mozilla Thunderbird). The clock on the bottom left is from the package osdclock.

Oh, and although I’m fine with trayer: if anybody knows a possibility to control the GNOME Network Manager without the need for a system tray, I would be very happy if you could tell me. :-)

Update 18-June-2008 23:45:

Matto Fransen used my howto to get ratpoison and nm-applet working together on Ubuntu. He also explains in his blog post, what may be necessary to get nm-applet working as intended in the first place — things I already had forgotten when I wrote this posting initally. :-)

Debian and GPRS with the Nokia E51

abe+blog@deuxchevaux.org (Axel Beckert) — Mon, 02 Jun 2008 00:39:02 +0200

A while ago I wanted to have internet over GPRS (either EDGE or UMTS) via my Nokia E51 working before I leave for the weekend. But whatever I tried, I always got an ERROR if I sent any AT command. Even ATZ and ATH resulted in errors. So started googling for all components: I found AT commands which are said to work with the Nokia E51, I found AT commands which are said to work with Swisscom GPRS and I found many sites describing how to setup a bluetooth modem.

But since the even those AT commands which should work with both, Swisscom GPRS and Nokia E51 didn’t work at all, I noticed that all the Nokia E51 howtos were using the USB cable. So I tried that, too, and it worked immediately. It looks very strange to me that the set of AT commands is dependend on which way you connect to the phone. :-/

So here’s my working PPP config:

hide-password
noauth
connect "/usr/sbin/chat -e -f /etc/chatscripts/swisscom-gprs"
/dev/ttyACM0
460800
defaultroute
crtscts
user "guest"
usepeerdns
noccp
bsdcomp 0,0
lcp-echo-failure 10000
lcp-echo-interval 1000
asyncmap 0
novj
nomagic

and the chat script (/etc/chatscripts/swisscom-gprs):

TIMEOUT 5
ABORT BUSY
ABORT 'NO CARRIER'
ABORT VOICE
ABORT 'NO DIALTONE'
ABORT 'NO ANSWER'
ABORT DELAYED
ABORT ERROR
'' \nAT
TIMEOUT 12
OK ATH
OK ATE1
OK 'AT+CGDCONT=1,"IP","gprs.swisscom.ch"'
OK ATD*99#
CONNECT ""

So I have now four levels of mobile computing available:

Nokia E51 with T9 and phone keyboard (for short texts)
Nokia E51 with Nokia SU-8W bluetooth keyboard (for longer texts and emergencies, see photo on the right)
ASUS EeePC (7", 630 MHz Celeron, 2GB RAM, 4GB SSD) with Nokia E51 as modem (complete computer, but still small, portable and nearly always with me)
Lenovo ThinkPad T61 (14" wide screen, 2.2 GHz Core2Duo, 4GB RAM, 160 GB SATA Disk) with Nokia E51 as modem (complete computer with power and disk space)

Should suffice in nearly all situations. ;-)

One month with Debian Lenny on the EeePC

abe+blog@deuxchevaux.org (Axel Beckert) — Mon, 02 Jun 2008 00:21:50 +0200

I ogled with an ASUS EeePC since it was announced, but didn’t want to order one abroad. So I waited until they became available in Switzerland. Digitec is the official EeePC importer for Switzerland and seeems also to be the moving power for yet to come the Swiss localisation of the EeePC. But initially they only offered imported EeePCs with German keyboard layout, but since I really got used to the US layout, I didn’t want to buy ay new laptops or keyboards with German layout.

When asking them about US layouts they told me they won’t import from the US and that their competitor Steg Computer is importing US models. But I wasn’t comfortable with Steg and EeePCs also were more expensive there, so I hesitated ordering at Steg.

So it was quite unexpected for me when US models showed up on digitec’s website. (Interestingly I never received any mail from their advertised EeePC newsletter, not even when they added 2G models t their repertoire.)

So at the end of March (and therefore later as most other geeks ;-) I ordered an ASUS EeePC at digitec. For me, white laptops look like Macs (and Macs are for sissies or masochists ;-) — so I had no problems to decide that I want a black EeePC with US keyboard layout. 2G was to small for my purposes (and also not that much cheaper) and 8G not available. So I went with the 4G, since Debian doesn’t need so much space if you choose the right packages (i.e. neither or at least not that much of GNOME or KDE ;-). I preferred the 4G over the 4G Surf because of the bigger battery capacity (and not because of the webcam which I consider funny but useless:-).

Initially the delivery date was set the 28th of March. Then it was subsequently set to “beginning of April”, “mid of April”, “end of April” and “beginning of May”. It finally arrived on 8th of May. In the meanwhile there were reports that even the 4G has been equipped with the smaller battery of the 4G Surf because of some battery shortage after some battery plant burnt down. But fortunately the delivery problems with black 4G US models doesn’t seem to have its reason there and my 4G has a 5200 mAh battery (at least according to its label and ACPI).

I also ordered a 2 GB bar of Corsair ValueSelect RAM so that I can pump up the RAM of my EeePC by factor four (for about 10% of the price of the EeePC itself) resulting in having half as much RAM as disk space. Well, I guess, I won’t do suspend to disk in that configuration… ;-)

The original Xandros based Linux only noticed 1 GB of the installed 2 GB as already noted on many other places in the web. But that doesn’t really matter, since it only lasted until I found out how to restore it from DVD in case I want to sell the EeePC later (e.g. for getting the successor). It’s fine for novices, but Linuxes feel strange if you can’t even get a console or a terminal with a command line. ;-)

The Debian EeePC installer worked fine except that it argued over a checksum error on our mirror which wasn’t reproducable after the installation anymore. I’ve chosen the EeePC to be my first (nearly) pure Lenny installation — compared to the three machines running Sid (i386, amd64 and kfreebsd-i386). It though has a few packages from experimental (mostly xulrunner-1.9) installed.

As window managers I have installed ratpoison, FLWM and FVWM. ratpoison — best described as screen for X (although you can’t detach and reattach) since it’s my personal preferences for being productive without big screen resolutions and flwm for a low-resource window manager which can be used intuitivly by both, geeks and non-geeks (and still doesn’t look like Windows at all ;-). And FVWM is installed because it’s my default window manager on all machines with bigger or multiple screens – to be able to compare it with my usual environment.

As web browser I’ve got Opera as primary browser (as everywhere else, too) and Conkeror (the EeePC is the test-case for upcoming Debian package of Conkeror) as well as links2 and lynx on the (nearly) text-only side on it, although I need them seldomly.

As office programs (as I would ever need some ;-) I’ve got AbiWord and Gnumeric installed since I already use a few GNOME applications (e.g. Network Manager, Twitux, etc.) and OpenOffice.org would take up 170 MB more disk space (then including OOo Draw and OOo Impress) and Siag Office is no more in Debian since years. (Initially I had OpenOffice.org installed instead of AbiWord and Gnumeric until I noticed that I need some of the GNOME libraries anyway.)

I also decided that I will need LaTeX then and when so TeX Live also got its chunk of the 4 GB of disk space.

I also have a bunch of games on the EeePC. Unfortunately there are a few games which don’t work well on the EeePC due to it’s resolution being smaller than 800x600, so I deinstalled them already again, e.g. I can’t play Cuyo on the EeePC but flobopuyo. Sauerbraten segfaults, but Doom (prboom with freedoom WADs) works fine. Further non-working games unfortunately include Battle of Wesnoth and XFrisk.

Still, although quite some parts of GNOME and GNOME Office, TeX Live, ScummVM with Flight of the Amazon Queen and Beneath a Steel Sky, GNU Emacs 22, Iceweasel 3 (aka Mozilla Firefox 3), Icedove (aka Mozilla Thunderbird) and the Iceowl (aka Mozilla Sunbird) are installed, only 2.3 GB of the available hard disk space are used by the installation (i.e. without my home directory).

Oh, and btw: Although except the very compact and a little bit wobbly keyboard the EeePC doesn’t feel really small to me (I’ve got quite small hands), but when I sat down in front of my 14” ThinkPad T61 after a day or two with EeePC, the T61, — especially screen and keyboard — felt huge as if it would be some 17” or even bigger notebook. ;-)

OTOH I still think that a 1920×1200 (which means nearly four xterms in a row) resolution on a 14” notebook would be a good idea, especially compared to the 1440×900 (which means nearly three xterms in a row) my T61 has. ;-)

Personal Resumée after one month

Pro EeePC

It’s geeky. If you show up with it, people want to lift it to see how much it weights and try the tiny keyboard. They’re surprised that 800x480 aren’t that small and that the performance isn’t that bad.
Very compact and robust. With the T61 I always fear that its edges are too close to the the outside of my backpack and could be damaged that way.
The price of course: CHF 499 at digitec (plus CHF 54 for the 2 GB RAM)
Runs Linux ex factory. So yu don’t have to expect that many driver hassles.
RAM upgrades are very straight forward and do not void the warranty. (BTW: The sticker over one of the screws which probably should prove the integrity can be removed and placed again easily… :-)
The weight. 0.92 kg can be easily held wit one hand, also because of less leverage effect as with full-size laptops.
The SSD despite it’s size. Being such lightweight you accelerate the EeePC unmindfully even when it runs. But it doesn’t matter, at least not to the hard disk. And it boots very fast, especially after the usage of insserv.
Intergrated Ethernet network interface. (Hey, the MacBook Air hasn’t a builtin one, not even an external shipped with it! ;-)
Three USB sockets (the MacBook Air has only one which is usually taken for the Ethernet network adaptor — Ok, with the EeePC usually one is taken for the Bluetooth dongle, but then are still two sockets left… ;-)
Great contrast on the builtin screen.
External VGA output. You have to configure X.org to make the virtual screen big enough (e.g. 2048×2048 instead of the default 800×800).
Despite its size quite a lot of space for modifications inside the case. Especially a bluetooth case mode should be no big deal.

Contra EeePC

The keyboard: keys smaller than usually (ok, wouldn’t work otherwise ;-), very wobbly, no precise contact depth (pressing Shift and Fn with one finger often doesn’t press Fn right), not all keys on the same plane, unusual offsets between the key rows (the number row has about half a key width offset to the left) or position of keys (I often hit Ins when I want Home, Del when I want Backspace or Fn when I want Ctrl, the ~ key is between Esc and F1, Up is between Slash and Right Shift, etc.)
The position of the power button: It’s exactly where I want to put thumb when holding the EeePC solely with the right hand. And yes, I already accidentially switch it off several times because of that. For luck the button doesn’t work at all when the lid is closed, because you still can reach it easily while it’s closed.
The mouse button(s): It only has two buttons which are one part you can press more to the left and more to the right side. And if you press it in the middle you randomly get either a left or a right click. You have to press it very hard to get both clicks at the same time. (e.g. to emulate a third middle button). Three separated mouse buttons would have been way better.
It has (only) a touchpad. I definitely prefer thumbsticks as the ThinkPads have, but got used to it, though. I have seen worse touchpads, too.
The noisy and not very precisely beared fan, which seems to strife its environment when the EeePC is being accelerated. Whih happens quite often because of its size and weight and because the SSD doesn’t mind acceleration. The fan does mind – and you hear it. :-(
Some programs need minimum 800x600 resolution to work well.

Pro ThinkPad (in direct comparision)

Thumbstick.
One of the best laptop keyboards around.
Three easy to distinguish mouse buttons.
Even ressource-hungry programs like Liferea work fine.
Quite big screen resolution (1440×900).
Bigger battery, space for additional batteries.
Could be a workstation replacement.

Pro Lenny on the EeePC

The installer image of the Debian EeePC Project works out of the box. All necessary drivers are available, if you include the non-free repositories and the eeepc.debian.net repositories.
Stable enough for daily use. (IMHO Debian Testing – and even Debian Unstable – is more stable as many other distribution’s stable releases, e.g. those from SuSE.)

Con Lenny on the EeePC

My favourite feed reader Liferea has changed its cache format since the version in Debian Etch, so I can’t sync Liferea caches between my Debian Etch running T61 and the Testing running EeePC. Well, fortunately the version of Liferea in Debian Etch still works on Debian Lenny, so I just downgraded the package to the version from Etch and set it on hold. I don’t use it on the EeePC though since it needs way too long to start (about 10 to 15 minutes compared to 1 to 3 minutes on the T61)

Summary

I’m very happy with the EeePC and I didn’t expect that it would replace my 14” ThinkPad in so many (but still not all) situations. :-)
