Compact Ubuntu

I’ve always hated the fact that on Ubuntu with the default themes, there’s far too much space wasted. The buttons are too tall, the treeview wastes too much space so that if you’re on eclipse or some other ide, you see a precious few items on the screen.

I’ve been trying to tweak it to no end - even looking to see if there are any ~/.gtkrc-2.0 tweaks. Found a few links such as this Making Eclipse look good on Linux - Max’s blog - however, didn’t really satisfy my need.

And so it stayed until today when I came across Clearlooks Compact Gnome Theme.

I love it - one more for my list of must-haves!

Hardy heron - first impressions

He he - finally got Ubuntu Hardy heron beta on my home and work laptop. first impressions below:

1. Wubi install from within windows is easy and works great. If after setting up so many boxes, I can go on and on about it, I’m sure that its great help for anyone who’s on Windoze. I mean, the barrier to entry has never gone down so much.

2. I guess once you’ve installed via Wubi and configured your system to your liking, you can uninstall and take an image that you finall install to a dedicated partition - isn’t that just awesome.

3. Comes installed with Firefox 3b4 -which is awesome. Given that FF crashes badly on yahoo, this might be a bummer for many people. Should probably have some first time customization that will let you install Opera.

4. Installation is super fast - took about 10 mins for wubi to install, reboot once, finish installation and reboot again. Grub default to Last selected would probably be a better idea.

The not so good

1. Wifi doesnt work out of the box - didn’t on my Dell Inspiron 1501 or the Dell Latitude D620. Its the ye olde broadcom problem. This is really the BIGGEST turn off. Hope it will get fixed by the time the final release is out. Meanwhile, had to jump through hoops getting ndiswrapper in. I didn’t go the broadcom fwcutter way since that only allows a 802.11b connection from what I read. I’m still not sure what fixed the issue - irrespective, I had to update the system and then things started working like a charm.

2. Compiz configuration isnt installed by default. If this is your first time on Ubuntu and you’ve come this way to see the awesome 3D desktop, then this is a bummer. Finding out what you need to do is a pain too.

I think that’s all there is to it. Its great once wifi starts working normally.

Firefox 3 Beta 2 on Ubuntu Gutsy

I’m having weird problems with firefox 3b2 on ubuntu gutsy - and as far as I can tell, I seem to be the only one. Did not find anything similar on ubuntu forums too.

Installed firefox 3 beta 2 from Mozilla to /usr/lib/firefox3b2 folder and created

lrwxrwxrwx 1 root root 27 2007-12-30 23:44 /usr/bin/firefox-3b2 -> /usr/lib/firefox3b2/firefox

When I launch firefox3b2, I get firefox alright, however, in the location bar if I type in a url and press Enter, nothing happens - absolutely nothing at all. I have to go and click the green arrow for the browser to open the URL. The search box is even weirder - neither the Enter key works nor does the mouse!

I’m at a loss - and nor can I find any similar experiences on forums etc - ideas welcome

SOLVED 01/20:Backed up my .mozilla folder and started firefox 3 b2 - no problems now

Sluggish Firefox - and what a hog!

Okay - for the past few days I’ve been irritated with the browsing experience at home. Pages (google reader, Yahoo mail etc seemed inexplicably slower than before - but they’d load alright - just seemed that teeny weeny bit slower that’s enough to leave you suspicious).

I first suspected my ISP (verizon) for frequent dropped connections (saw the DSL modem lights reset a couple of times a day), then my wifi modem (not a high end one), then spyware/malware. So after the usual barrage of tests - wifi interference sources/anti virus/anti spyware/cable tests etc, I still hadn’t nailed it.

Finally, used procexp ( you can use plain ‘ole Task manager too - this is just flashier) and saw that FF had 330 MB of RAM with 3 or 4 tabs. Also, just plain clicking on a text box was slow, typing into a text field would echo characters after a noticeable delay - so this was definitely a browser problem.

When you have eliminated all which is impossible, then whatever remains, however improbable, must be the truth.

– Sherlock Holmes

Ain’t that an apt quote??? I love the addons I have and probably I have one too many. This page on problematic addons  was a life-saver - after disabling a bunch of infrequently used addons (stumble upon toolbar, google toolbar, browser sync, adblock filterset g, foxy tunes and some more), I’m back in browsing heaven. The only addons I have now enabled are

• diigo toolbar
• all in one gestures
• Adblock
• Flashgot
• Piclens

What a relief!

BTW, addons are also the latest attack vector. So be wary of who you let into your browser!

Python, cygwin, TurboGears, mysql hell

Ok - here goes - I’ve always liked python, though definitely a noob. I was interested in python on the web and after a bit of googling, seems like TurboGears is the way to go.

First things first - decided to use mysql as the database (already have it on my machine and didn’t want to install one more database (postgresql/sqlite). Now it turns out that MySQL doesnt have a cygwin package. More googling - mysql server can’t run on cygwin due to something to do with pthreads. You can compile the mysql client on cygwin though.

That’s what I decided to do - grabbed the Linux tar.gz source from mysql.com, got it into a directory and ran ./configure –without-server, followed by make && make install. All went through fine -other than the fact that it was time consuming and pretty boring (more so since I had to download and install gcc, bintools first in cygwin)

I thought I’d got through the hard part and what remained was to install python-MySQLdb package. Off I went to

easy_install MySQLdb

No luck there - package build failed with missing library -lmysqlclient_r. Turns out that the ‘thread-safe’ version of mysql client (mysqlclient_r) is preferred but the mysql build doesnt build this by default. What a shame!!!

Anyway, so I wasnt going to redo the whole mysql client library build again - more README files and googling later, grabbed mysql-python-1.2.2 tarball, got it into a folder, edited site.cfg and changed ‘threadsafe=false’. The next run on python setup.py build worked properly, with the python mysql linking against the non threadsafe mysqlclient library.

Think troubles are over yet? No way.

Off I went to test - started the python interpreter and did a import MySQLdb, and got a Permission Denied in some ‘egg’ file!!! What the heck are these egg files anyway. Well, I did’nt have much of a clue and more google later got educated that these are install packages used by the easy install system. The more I looked, the more it seems that the easy install is anything but easy :(. Anyway, this one had me floored - since I couldnt get to the line of source where the error was and had no clue how to view the contents of an ‘egg’ (they’re zips - but I didnt know that and very helpfully there’s hardly anyplace where they say that they’re zips with the extension of egg!!! Baaah!! - why couldn’t they just use .zip?)

More and more hard googling - and this time the info’s really sketchy till eventually found a post from a guy who asked the exact same question. Guess what, the easy_install system unzips the eggs to some folder (pointed by PYTHON_EGG_CACHE env var) and there I needed to do a chmod a+x on the _mysql.dll. Well so I did echo $PYTHON_EGG_CACHE and the var isnt set!!! Admittedly at this point, I’m not looking sharp either - what started out as a quick spin has become a quagmire of installation issues - but I’ll be damned if I let it sink me!!! Eventually, had the Eureka moment and checked ~/.python-eggs and sure enough found the truant _mysql.dll. Quick chmod a+x and presto - import MySQLdb worked!!! YAHOOOOOOOOOOOOOOOOOOOO!!!!

And now back to where I started - went back to turbogears, did a tg-admin quickstart, setup a mysql database and started with python start-testproject.py. Guess what - no luck yet - turns out that mysql cant client to my windows server with a socket.

More googling - and this time its really desperate - and more enlightenment - the windows mysqld doesnt do unix sockets - how do I force tcp/ip? Simple - use 127.0.0.1 as hostname in the connection settings instead of localhost!! Finally something that was easy to fix. Finally after 8 hours of on and off hacking away at installation issues I’m glad to see a turbogears web page.

Bottomline: Python’s great, from the looks of it, turbo gears seems well designed. Mysql is a great database - a cygwin native server would be great - or atleast a client package. But if one has to run through all these hoops just go get a ‘quick spin’ then adoption’s going to be difficult.

I havent tried RoR - but has someone tried a similar thing on cygwin (cygwin, ruby, RoR, mysql)? How does the experience compare - is it any easier to get off the ground?
