Are there any drawbacks to creating ext4 file systems with 2^32-1 inodes?
I have a 1tb drive and I would like to store 800 million to 1.5 billion small files on it. It seems that the max is 4 billion, so I'm wondering whether I could just set it to the max when creating an fs, or I should find some other solution.
The adapter sort of works out of the box without installing additional drivers, but it's very unstable - after a couple minutes speed slows down to a crawl (can't even open google), plugging it in and out helps with the issue temporarily.
Asus has a drives with Supported Linux kernel : 2.6.x, but nothing else. Is there any way to fix this issue?
I'm using pyvirtualdisplay (which launches Xephyr) and xdotool to automate mouse movements. While I know it works, I can't see the mouse cursor. Is it possible to add it? I've added fluxbox window manager with subprocess.Popen. Is there some application to draw the cursor in the same window?
Is there a tool to replace fancy utf chars like U+2018 (LEFT SINGLE QUOTATION MARK), U+2019 (RIGHT SINGLE QUOTATION MARK) with normal quote chars: ', etc. like lodash deburr command does?
My Xubuntu 14.04 installation stopped booting all of a sudden: after rebooting I just see a flashing _ in the top left corner of the screen. Holding Left-Shift during boot won't open any menu, Ctrl+Alt+F* will not open a terminal I can type in.
I've reset BIOS settings, which did not help, then made a bootable USB stick with Ubuntu. I can now boot and I see that the data on the disk with OS is intact, I've checked the disk with badblocks and it found no errors.
Is there any way I can locate any details as to why the system does not boot?
When I try to remove any package, I get

/boot partition has 263 MB of space and I've removed some old kernel files with rm -f /boot/*3.13.0-3* to free space before. I don't think I've purged linux-kernel packages back then.
Either way now I can't even use the answer from here - when I try to apt-get purge linux-image-3.11.0-20-generic I still run into the issue with with initramfs.
I have 2 displays on my PC - an IDE is open fullscreen in one display and Firefox is open fullscreen in another display.
Since I mostly use the keyboard, it's annoying to have to grab the mouse to switch the focus to Firefox and back to the IDE all the time.
Is there a shortcut I could use to switch the focus to "largest window" on display 2 if focus is somewhere in display 1 and vice versa?
I have the sound popup thingy displayed about every minute, even without changing any volume settings, or clicking/pressing anything. It's happening in xubuntu 13.10 and looks like this
How can I fix it?
Is there software to install on an ubuntu server, and then use to collaboratively edit text files, sometimes adding some attachments? it's important that no data is lost if 2 people save the same doc with different contents at the same time. I've found seafile, but it seems too complicated considering it need 3 ports to work, and requires manual installation.
I have a server listening on a socket file /tmp/any.sock and I want to write something to that socket. If it would be listening on a port, I would use echo mymessage | nc localhost 1234, but nc /tmp/any.sock or echo mymessage > /tmp/any.sockdoes not work.
Is there an easy way to limit user bandwidth usage to say 10kpbs? Other users should not be affected. The best I've found is tc, but it seems way too complicated to do such a simple thing.
I'm using guake and zsh and I'd like to use Ctrl+Shift+Arrows to select word-by-word, Ctrl+Arrows to jump around words, Shift+Arrows to select char-by-char in terminal. This is working as expected in applications like gedit.
Is it possible in any shell?
Is it possible to setup a remote server to store a folder with encrypted contents, which is impossible to read by the server, but is editable by multiple clients?
It seems like duplicity is a tool for this, but I'm not sure if any data loss is possible if 2 workstations try to edit the same file simultaneously?
I'm getting a lot of messages like these:

The problem is, I don't recall sending anything. How do I find out which software is sending these messages? How do I read them?
I'm trying to a make a simple .deb package, which would basically edit a config of another package I listed as a dependency.
I added the required manipulations to the postinstall file.
The problem is I can't find a way to package an example config, which should be copied and edited from the postinstall script.
At the moment I just have a folder with the sample config, of which I'm creating a tar.gz and orig.tar.gz, then dh_make in that folder, edit the generated files and run debuild. However if I open the resulting .deb file with an archive manager, I can see that the sample file was not included at all.

Oracle JDK 7 is NOT installed.
dpkg: error while cleaning up:
subprocess installed post-installation script returned error exit status 1
Errors were encountered while processing:
oracle-java7-installer
So apparently it's trying to fetch a bad URL. I've installed Java manually, but now the package is stuck as a half-installed and every time I apt-get install anything, the error appears again.
apt-get install -f shows "1 not fully installed or removed." package and fails with the same error. I've tried dpkg -P oracle-java7-installer, but it fails as well.
How to remove this half-installed package?
I'm using Ubuntu 11.10 and sometimes Nautilus icons stop being displayed and it looks like this:
Is there a way to fix this without rebooting?
When I open a directory in nautilus using a shortcut, for example "Desktop", the top bar is of nautilus is showing: left arrow, Home, Desktop. When I press the arrow, I get to see links to root and "/home/".
How do I get it to never show the arrow, but instead always show all the parent directories?
I have seen tried always_use_location_entry, but it shows text instead of click-able links.
I'm having a problem with workplace configuration - it appears as a 4x1 box when I do Ctrl+Alt+→. I have 2x2 box at the other installation (was that way since the start), so how can I make it this way instead of 4x1?
I've been using Windows for a long time with the HTTP Analyzer application, which is basically Wireshark for http/https protocols and is able to actually process https requests the same way as HTTP.
Now I'm using Wireshark in Ubuntu, but it doesn't capture the HTTPS traffic, which is expected but not convenient. I guess the windows app was somehow hooking to the lower level OS events of decrypting the HTTPS response - is there something of this kind for Ubuntu?
