node.js:201
throw e; // process.nextTick error, or 'error' event on first tick

Error: require.paths is removed. Use node_modules folders, or the NODE_PATH environment variable instead. 

You can find sample code causing error here.

I’ve tried setting NODE_PATH in bash but with no success.

Then I’ve looked into meteor script (under /usr/bin) and saw that meteor is setting NODE_PATH by itself (it is pointing to /usr/lib/meteor/lib/node_modules directory). I cloned required package directly from github into /usr/lib/meteor/lib/node_modules directory and my application run wihout any errors.

But than I thought that it is a good track and decided to clean entire AIR . I’ve deleted ~/.appdata/Adobe/AIR/ directory. And that was it! I could use Vimeo Desktop Uploader once again.

When I was checking space left on my hard drive (using df command) I’ve noticed that

Code block

lukas@acer:~$ df -h
Filesystem Size Used Avail Use% Mounted on
...
/dev/sda3 126G 117G 2,5G 98% /home

Reserved Block Count on partition

I found an explanation (using Google ofcors) that some percent of blocks on each partition is being reserved to reduce system defragmentation, allow root login for maintenance and to allow Linux system logging facility to function properly in case of lack of free space on partition. It is called Reserved Block Count and it is set to 5% of partition size by default.

You can check current Reserved Block Count value using dumpe2fs command

Code block

lukas@acer:~$ sudo dumpe2fs /dev/sda3 | grep "Reserved block count"
dumpe2fs 1.41.12 (17-May-2010)
Reserved block count: 1653590

Block size of my partition is 4096 (it can be checked using dumpe2fs command). So reserved space on my partition is about 6,3 Gb and equal missing size from hd command.

How to change Reserved Block Count
Reserved Block Count for given partition can be changed using tune2fs command

Code block

sudo tune2fs -m 0 /dev/sda3

where /dev/sda3 is your file system identifier

-m option sets the percentage of reserved file system blocks (in this case it is being set to 0%)

Then I’ve checked again free space in my system:

Code block

lukas@acer:~$ df -h
Filesystem Size Used Avail Use% Mounted on
...
/dev/sda3 126G 117G 8,8G 94% /home

I have additional 6Gb on my home partition!

Is it safe?

You can disable Reserved Block Count (by setting the percentage of reserved filesystem blocks to 0%) safely on not-system partitions (such as /home partitions). You shouldn’t do this on partitions used by root (especially / and /root) and on partitions used by OS for logging and storing temporary files (e.g. /var and /tmp).

I got followin message:

Code block

OpenOffice path before fixup is '/usr/lib/openoffice'
OpenOffice path is '/usr/lib/openoffice
Attempting to load the system libmoon
Segmentation fault

I found following bug in Google and I’ve followed last note saing “Uninstalling libmoon solved the problem”.

So I’ve uninstalled libmoon and then I could lauch Chromium browser.

What is more important for developers, from friday Bitbucket will offer a free account for five developers and unlimited numer of repositories (ideal for small teams). Comparable account on github.com (popular collaboration site for Git, main Mercurial competitor) would cost us $7 per month.

I hope that github will soon offer comparable free account. I’m using Git and don’t wan’t to switch to Mercurial.

Code block

rails new helloworld_project

command and installed sqlite3 gem.

When I tried to start application I got error dialog box with message:

“The program can’t start because sqlite3.dll is missing from your computer. Try reinstalling the program to fix the problem.”

Another confusing error…

Luckily I was able to fix this quickly.

First I’ve downloaded sqlitedll zip from http://www.sqlite.org/download.html site, and then I’ve put sqlite3.dll to my ruby installation bin directory.

Then I was able to successfully launch my rails application.

Of course running command

Code block

gem install rails

didn’t work.

I received following error message:

Code block

> gem install rails
ERROR:  http://rubygems.org/ does not appear to be a repository
ERROR:  Could not find a valid gem 'rails' (>= 0) in any repository

I’ve created .gemrc file in my home directory and specified http_proxy option and added following line

Code block

http_proxy: http://proxy_ip:proxy_port

into it.

But that didn’t help. I was a little bit confused because it was the way I did it last time (very long time ago thou).

I’ve tried to use -http_proxy in command line but gem could not understand this option (why, if documentation say it is a proper way to configure proxy?!). Then I’ve tried last option mentioned in documentation (-p as a shortcut of -http_proxy option) and, surprisingly, it worked.

I have to remember that: use

Code block

gem install -p http://proxy_ip:proxy_port rails

next time.

Personally, I do not like this solution. First of all I can not switch back to previously used applets. There is also problem with space between icons in applet. For example distance between other elements in my taskbar (e.g. clock and Pidgin icon) is less than between indicator applet icons (which looks strange on my desktop). Moreover I use only web interface to my Gmail account so I don’t need envelope icon for Evolution/Thunderbird events. Having unused icon in taskbar is irritating, but I managed to remove it.

I executed following command:

Code block

sudo aptitude purge indicator-me indicator-messages gwibber

Then I removed Indicator applet from by taskbar and then added it once again.

It replaces new tab page with your predefined visual bookmarks. Pretty straightforward but can save a lot of time entering once again Gmail or Google Reader address in browser.

The only thing that was annoying me was a default window button layout. Minimize, maximize and close buttons were moved from right to left.

After a minute Googling for solution I found it. I had to run gconf-editor (ALT+F2 to open Run command window) and then change settings for apps->metacity->general->button layout property from

maximize, minimize, close:

to

:minimize,maximize,close

Colon position is most important: it determines buttons position in window bar.

Changes were applied immediately and I had good, old buttons layout.
