Alfresco Enterprise CMS /etc/hosts problem

I've been trying for the last 4 hours to make a test installation of Alfresco on a Ubuntu 8.04.4 LTS virtual machine. Unfortunately, I had a very strange problem about some ObjID already in use. I've tried everything,, changing ports, disabling apparmor, reinstall, everything...But, after those 4 hours..or maybe more, I just found the answer here. The problem is that in /etc/hosts I had a different IP for my hostname, that's because it was actually a clone of another machine, so it had the original's IP address in that file, and I had to change the IP for not having an IP conflict, ...anyway, after modifying my /etc/hosts file, I reinstalled everything, and works smoothly.

GMail storage increase rate

Since I don't have anything more important to do, I was just noticing the counter on the GMail welcome page, and it's actually increasing with 4 bytes per second. Actually, there are more sick guys then me out there. This dude actually calculated the time necessary to increase the storage from current to 10GB...and the result was...20 years! ..and the increase rate per day is something around 350KB. For me I think it's quite enough, because although I'm using GMail for many many years, and for some time now, I'm gathering all my e-mails to this account, I'm only using aprox. 1GB of storage. Mainly because I only keep important e-mails, and delete all the crap / spam / newsletters that I'm not interested in reading 1 year from now.

But what happens to girls that spend most of their time in front of their computers watching pics and movies from e-mails sent from another bunch of girls with nothing to do than just forward them around? Maybe it will take Google 20 years to get to 10GB storage, ...but it will take me a hell lot more to fill that. Anyway, I know girls that can fill up that 10GB in 1 year. And that including those 20 days of legal vacation around here. :)

So, ..I was just checking now how Windows Live is coming with the storage. Yahoo is unlimited, although I guess that if you're planning to store a 1TB e-mail storage, and make sure you grow it by the end of this year, Yahoo will suddenly enable e-mail quota again... :) But, Microsoft says "Windows Live Hotmail includes ever-growing storage to provide you with as much storage space as you need, provided that you send and receive a normal amount of e-mail. Your inbox capacity will automatically increase as you need more space." So, I guess that Microsoft somehow automagically (I know, it's incorrect, ...but I just learned that from CPanel's funny status messages) increases your quota depending on how much storage you're using. And now I was thinking that I'll never loose an e-mail with this policy. Quota gets to max, Microsoft increases quota, e-mail arrives. WRONG! Microsoft also says "If your inbox surprises us by suddenly and abnormally skyrocketing in size, you may get an e-mail from Windows Live Hotmail asking you to slow down, move e-mails from Windows Live Hotmail to your desktop, or to delete some old e-mails. Please read these e-mails and follow the advice provided in them to continue to enjoy ever-growing storage, which should be plenty of storage for you so that you don't have to worry about running out of space." So, there's no number in "ever-growing storage" ...and how is that "ask you to slow down"?..Like, you're responsible for e-mails you receive, and you should tell people that sends you e-mails to slow the fuck down. Funny, indeed. There should be a trick in Yahoo's infinite storage, but I'll have to dig more on their website.

[update]: This is what's on Yahoo about their unlimited storage:

How does unlimited storage work?
It’s pretty straightforward—users who follow the Yahoo! Terms of Service and our anti-abuse controls can consume an unlimited amount of free email storage. This will apply to both new and existing users.
Wait – what? Wow!
How can Yahoo! afford to give away unlimited email storage?
By hiring outstanding engineers, of course! Ours have been hard at work developing an incredibly efficient backend storage system. This storage system gives you the option to never delete another email! Unless, of course, you want to. The purpose of unlimited mail isn’t to provide an online storage warehouse. Usage that suggests this approach gets flagged by our anti-abuse measures. In order for our system to work efficiently, our abuse control systems may limit the number of emails you may send or receive when it appears your usage is excessive. These abuse control systems may also impact the rate of growth of your account and you may need to create new folders or move some emails to other folders, if you are experiencing response issues.
How will you prevent abuse?
Yahoo! employs a variety of anti-abuse methods. If our anti-abuse system detects potential abuse we may take action. These anti-abuse controls enable us to better identify users who are not using the service appropriately under the Terms. Our goal is to ensure that everyone benefits from unlimited storage!
So, I'm pretty sure they have something like M$ has. If you receive too many and too big e-mails you'll receive an e-mail from Yahoo like this:

From: Yahoo's Outstanding Engineers :)
Subject: Storage full
Message: Please tell your friends to slow the fuck down, We bought all harddrives we could find. Please hold them off a day or 2. We're just going to fly to the factory and get some cargo flight with some more, install them, and after that, you can continue your messaging as usual. :)

EEE PC 1008HA hotkeys on Ubuntu Lucid Lynx 10.04 LTS

So, it seems that Asus is somehow sniffing on the installed operating system and acts accordingly. So the way acpi works is related to what OS the mainboard thinks you have. Newer kernels don't advertise themselves, so you should do that manually by adding "acpi_osi=Linux" to /etc/default/grub file to GRUB_CMDLINE_LINUX_DEFAULT variable so it will show like this:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=Linux"
Then run "update-grub" as root or with sudo, reboot, and that's all.

Ubuntu 10.04 LTS updates

After the latest updates installed, there's the battery icon both in Notification Area and Indicator Applet, and notification about battery charging and discharging got bigger, which looks uglier on my small Eee PC screen. Hopefully, they'll fix this by the release date on 29th this month. They'll also have to fix my hotkeys problem, and not that grub fix that finishes the ethernet card.

[update]: you can hide one of the icons by left-clicking the icon and then "Preferences", and then on the last tab called "General" check the "Never display an icon" option, and then Close. My choice was to never show the icon from Indicator Applet, because the one in Notification Area is smaller, and I like small things on my small Eee PC desktop.

[update #2]: after disappearing again, it reappeared today. I guess it has something to do with update-manager but I'm not sure what exactly. Still, after few updates including acpi-support, no support for my hotkeys. Hopefully they'll get all bugs fixed by the end of next week, when the release date is coming. They've also discovered a memory leak in package, but fortunately, I don't seem to get affected or at least, the startup time looks ok to me. The only thing that's slowing my boot is after the login screen, and it's because AWN is loading. Unfortunately, I like it too much to see it gone, so I'm not uninstalling it soon, I'll just have to get used to those 10 seconds of freeze before everything appears on my desktop after the login screen.

Avant Window Navigator

AWN it's a cool dock-style panel that I just discovered today. It was added automatically for some plugins of banshee media player. I tried installing it because of the lack of equalizer of Rhythmbox. Unfortunately, wasn't very impressed by the performance, and the banshee-telepathy plugin to be able to change my Empathy status, was missing from the repository, and I wasn't able to install.

Anyway, AWN, looks great, works great on my EEE PC, and has really nice effects, ..and applets. All packages including extra applets are:


I just took a print screen of how I've made it look...

TeamViewer for Linux (beta)

So, TeamViewer just released the Linux version of their software. There is an archived version, and also RPM and DEB packages for whatever distro you might use.  It's beta, but it's worth trying.

GMail insert invitation

There's a new feature in GMail. It allows you to send invitations to events directly from your GMail interface. It automatically inserts the event in your calendar, and to the ones you send the invitation to. GMail blog post made me very proud of being the same nationality as the girl who posted this to their blog, a software engineer called Oana Florescu, a very ..romanian name.

CheckGmail is a nice GMail checker. It blends in the panel because the current version has transparent icons, and it's a nice thing to have, if you're in my place and you uninstalled all e-mail clients because you wanted the browser version and not another software installed on your computer. On a new e-mail, the icon looks like this..

Bad part is that it won't work only with "apt-get install checkgmail". After installing, you'll have to get the latest SVN version with "sudo checkgmail --update". When asked, press capital "Y". That's all folks!

new improvements to Google Docs

Packet Tracer 5.2 font problem

I tried to start the newly installed Packet Tracer 5.2 on my Ubuntu 10.04 LTS beta 2. Unfortunately application fonts were really fucked up. But, there is a fix for that.

- first of all, Packet Tracer runs on its own QT4 libraries, and you don't want that. So, to change that, edit this file "/usr/local/PacketTracer5/packettracer" and comment out this line:

- after that, you have to install whatever QT4 missing packets you have to install this:
apt-get install libqt4-gui
apt-get install libqt4-webkit
apt-get install libqt4-qt3support

if it still doesn't work after all this, just do this:
apt-get install libqt4-dev

Then your Packet Tracer is ready to go and simulate Cisco equipment.
Have fun!

Ubuntu 10.04 LTS beta 2

Unfortunately, Ubuntu still has to fix some of the bugs people have until the final release gets out by the end of this month. I'm testing it on my Asus EEE PC 1008HA...and I have the following annoying bugs:

- after login, when my desktop appears, indicator applet icons and notification area icons get messed up. It all sorts out after a log out, log in.
- eeepc_laptop module is not loadable, ...the error is "no such device"..still hoping it will work soon because I miss my hotkeys functionality. There was this "fix" available on the net, but unfortunately, makes your ethernet card unusable.
- empathy should have a default window size for every chat that should be setup in gconf, or at least should remember the chat window size settings for specific users. Unfortunately, it doesn't, any of them. Hopefully, at least the remembering will be done by the final release of 10.04 LTS.
- this is something related to rhythmbox "IM status" plugin. Although it sets the correct status when the song is changing, sometimes the status empathy shows in the dropdown list is stuck.
- and 1 more for empathy. Sometimes, using the default Ambiance theme, the status bar in empathy just disappears, and the workaround I found is to go to Preferences > Appearance and change to another theme, and back to Ambiance theme. Status dropdown list appears automagically. :P This shit happened to 9.10 as well, and I discovered this workaround back then.
- and the last one,..there's a huge space between icons in indicator applet, and it annoying in my 1024x600 screen. They can have some custom gconf setting for that, or they can make the distance smaller by default.
- I was just joking, this is the last one. :) I guess there's something wrong with the Intel graphics drivers. Because in 9.10 I had no problems running Compiz, but in 10.04, there is a flickering line in windows while moving them, and I don't know for sure why.

And a good thing I've noticed about 10.04 LTS beta 2. Wireless drivers. They're excellent. In 9.10 I always used the tutorial I had in my blog to update drivers every single kernel upgrade I was doing. But this time, wireless drivers work well out of the box, so there's no more need in compiling new ones.

How to change Ubuntu Karmic Koala and newer login screen

As System > Administration > Login Screen doesn't offer so many options anymore, the way login screen looks can be changed like this:

1. logout of your current session and return to login screen
2. get your command line interface (CLI) by pressing Ctrl+Alt+F1
3. login using your account, or root account.
4. type export DISPLAY=:0.0 for the $DISPLAY variable to be available to users
5. type sudo -u gdm gnome-control-center - this will open up gnome control center for "gdm" user; this is the user that is used for the login screen.
6. switch to graphical display using Ctrl+Alt+F7
7. configure theme, background and whatever else you want for the login screen
8. close gnome-control-center and login using your account (you should already have the new theme at your login screen)
