Ubuntu :: Created Free Software For Windows That Will Allow A Regular Whiteboard Or Monitor?
Feb 24, 2011
I found a guy who created free software for windows that will allow a regular whiteboard or monitor to function just like a $5000 Smartboard (really a giant sized iPad run with a projector rather than backlighting), and all it takes is an infra-red pen, a Wii remote, and a bluetooth linkup to a computer to do it. The pen can be built with a Bic penshell and a Radio Shack LED if you follow instructions.
This is called a Wiimote. His version doesn't have all the education-specific apps that Smartboard does (Smartboards mostly designed for classroom instruction), but it does seem to allow everything else, ie, you can run any windows program on it. Is there a Linux version of this or some alternate? I'm worried about BSOD in the middle of a presentation, and I'd like some comfort that won't happen to me. And I might be inclined to pay a programmer to duplicate any educational software that I can't get otherwise.

I've got a question on free disk space. I'm currently running CentOS 5.5 on in Xenserver virtual environment. We've had an issue with disk space. My question is as follows: - from a ssh connection i run df -h this gives the value of 90% used leaving me with 9GB. If I use system monitor via a VNC connection the free disk space value is 20GB free on the same volume. Which one is correct? I do use SNMP to monitor the same volume and should alert me when < 10% is free I know this works as I set the alert threshold to < 90% I get an alert.

I have a system with 1 GB RAM. I'm running KDE 4. I created a tab to look that the Physical Memory in the System Monitor program, which I assume appears to look at the same stats that "top" looks at. In that Physical Memory tab I have 3 tables: Used Memory, Free Memory, and Application Memory.The Used Memory table shows that the system is using .94 of .98 GiBytes. The Free Memory table shows that the system has .5 GiBytes of RAM free.
However the Application Memory shows that only 339 M-Bytes of RAM is being used.Note that "top" shows the same info.So where is the other .6 GiBytes of RAM that the Used Memory table shows as being used?If I look at the process table which is supposed to encompass all of the processes running, including the ones for the OS, then it appears to add up to the 339 M-Bytes being used in the Application Memory table. Is the rest of the memory being held in reserve by the OS to be used as needed? If so, then why when another application is opened the Free Memory goes down instead of staying constant?I also noticed this memory "black hole" when I was running 11.0 on a system with 4 GB of RAM. The OS appeared to "take up" a large chunk of memory that was NOT being used by any applications and making it "disappear" - meaning that the applications were using about 1.3 GiBytes of RAM and Free Memory was showing only .7 GiBytes instead of the over 2 GB of RAM that should be free.

I have an Intel setup with 64bit Ubuntu. I have an NVIDIA graphics card. When I used compiz, I found that my mouse would follow newly created windows. (e.g, I would bring up terminal and if I hit F1, the mouse would move to the upper right of the screen by itself. I have since turned off compiz which resolves the issue. where I can turn it off/on.

I'm using Ubuntu 10.10 (Maverick Meerkat) on my HP laptop. My office desktop uses Windows 7 Home Edition. I created an adhoc connection on my desktop pc because I also want have an internet connection on my laptop. But Ubuntu seems do not detected the adhoc I created on my pc. I also tried to connect using the hidden wireless network and entering all the necessary access (wep key, etc...) but still didn't work. Is there any way that I could connect my Ubuntu on a adhoc? Is that possible?

I am migrating (many) .tex files created in WinEdt under Windows XP to Kile under openSUSE. Kile uses by default UTF-8 encoding, whereas my files are apparently ANSI... I infer this last from my failed attempt to manipulate WinEdt into encoding in UTF-8 for me, as follows: I had inserted the comment
% !Mode:: "TeX:UTF-8"
into my .tex file (following Re: UTF-8). When I had WinEdt open this file it objected in no uncertain terms: ``The file is not in UTF-8 format: Loading as ANSI.''
Summarizing, WinEdt provides me files encoded as ANSI. Yet in Kile -> Settings -> Configure Kile -> Open/Save there is no option to select ANSI.
Kile will open these files in read only mode, and I can then save them with a new name, and proceed -- but it would be more satisfying to know the ``proper'' approach to this.

I have a Western Digital 3TB USB drive connected to a Raspberry Pi 2 running Raspbian Jessie. I created an 30GB ext4 system partition and a NTFS Data partition using the remainder of the drive. I formatted the NTFS partition as follows:
sudo mkfs.ntfs -Q -L Data /dev/sda2
The drive works fine on the Pi but when I connect it to a Windows 7 pc the pc doesn't recognise the format of the Data partition and can't access it.
On the Pi I ran:
$ sudo fdisk -l /dev/sda2
Disk /dev/sda2: 2.7 TiB, 2968557453312 bytes, 724745472 sectors
Units: sectors of 1 * 4096 = 4096 bytes
Sector size (logical/physical): 4096 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
[Code] .....
Partition table entries are not in disk order.

I'm dual booting windows vista and ubuntu hardy on a multi-partitioned Dell D630. I created a partition using mkfs -t ntfs. Linux has no trouble reading/writing to it, but every time I boot into windows, chkdsk tries to "fix" the partition, fails, and tells me that the partition is corrupted. Can anybody suggest a way to convince vista that the partition is indeed ok, or else another way to create the partition so that vista can recognize it?

In my system, I had installed windows XP first and had deleted one of the partitions (made free space.I am not a techy. I dont know the exact term). In that space, I have installed PC Linux OS (Linux). Now, I want to use that free space to Install Ubuntu by removing the PC Linux OS. When I boot with the live CD of Ubuntu 9.1 to install, in one of the steps, it says the system does not have any OS. It neither recognises windows nor the other linux. Kindly help me. What should I do now. Could I manage to install Ubuntu without completely formatting the system all again.

having trouble consolidating the free space on their Windows Vista partitions.
Most of the information you need is here: [URL]
The problem is that there may still be some system files running in the background that prevent all of your free space from consolidating. For some reason, I didn't find many partitioning guides that mention this.
If you find at Step 11 that your shrink space is still abnormally small, what you need to do is go back and open PerfectDisk. With "Consolidate Free Space" selected in the drop down box, click the "Boot Time" button. This allows PerfectDisk to consolidate free space while your hard drive is offline. Once this is done, go back to Step 10 and everything should work from there!

I have a fileserver running openSUSE 11.2 and samba services for file access from MS Windows based workstations. My question relates to changing default permissions on files and directories created from the windows clients.
Following are extracts of the /etc/samba/smb.conf file :
Even with the above entries, sometimes there are files and directories created by the windows clients having permission
Probably my lack of understanding in ACLS.

I mean something like Teamviewer so i can click-click and be there in no time, without knowing my IP (it's dynamic so that's a toughy, when i was using VNC i had to write a crontab script that uploaded my IP to a place i could always access every hour). Looked trough tons of apps, Googled for hours, found nothing.

I now have Windows XP installed, with 30GB of free space on the end of my hard rive. If I install linux there, will it cause Windows XP to fail? Last time I tried this, it says hal.dll was not found. However, that may have been caused by having five partitions. Do u think its safe now that I'll only have 4? Will Windows XP fail if I put in a partition in the free space?
Why does it says I'm using Safari in Windows, I'm using Google Chrome

So I just recently moves a lot of data from ubuntu to a pc with windows XP. I do a lot of html editing and I noticed, for many of the HTML documents I have, a duplicate was created that is named with a "~" at the end.
What are these files? Is it safe for me to delete them?

Whilst in fedora i deleted files off my second hard drive to free up some space, i deleted over 10gb worth of data. When booting back in to my windows partition it doesnt recognize the free space instead it thinks the hard drive is still full even though i deleted the data.Not to sure as to why this has happened, as im sure i have deleted stuff of this hard drive before from my linux partition.Any help would be greatly appreciated as my 70gb hard drive is full with only 20gb of data to show for it

Am I asking too much for a FREE OS? Everybody spend their precious time to help others, that's very helpful.But it seems like there is no support from UBUNTU team,how could we even get through the barrier of not using Microsoft's OSes? No free lunch of course, but it seems to me some issues have never really been solved.I read lot's of people have problem with their WIFI, not just for my OLD USB wifi adapter. I don't have problem with WIFI in XP/Server.
I posted here and there, and seems like no answer, and I do not get any reply from UBUNTU support team,forgive me if I run out of google's keywords.I just need a simple answer, is my WIFI going to work in UBUNTU with a layman effort? I like linux and UBUNTU had put great effort in providing me such a great OS, but if a basic internet connection will need to spent sooo much time to setup, and it still doesn't work. IS IT WORTH to switch to UBUNTU at all
