• Wacom tablet or Evoluvent Vertical Mouse

  - by Bob Smith

  Having tried a number of mice that didn't help with wrist pain, I am contemplating buying a Wacom tablet or Evoluvent Vertical Mouse. I have heard great things about both of them. What do you recommend for someone with wrist pain in both hands that seems to be getting worse by the day? PS: I work mostly in Windows and Visual Studio environment. I currently have the MS natural ergonomic keyboard. I have started taking regular breaks and am also planning to see a doctor.

• Ubuntu: move logs from /dev/tty8 to different terminal /dev/tty12 or get rid of it.

  - by Casual Coder

  I want to know how to move or get rid of /dev/tty8 log output in Ubuntu 9.10. /dev/tty7 is my regular X session. When I am switching user to test account where I can try and test setups and configs I am at next available console i.e. /dev/tty9 because /dev/tty8 is taken by log output. Where can I configure this ? All I've found related to /dev/tty8 is commented lines in /etc/rsyslog.d/50-default.conf. I changed it like that: daemon,mail.*;\ news.=crit;news.=err;news.=notice;\ *.=debug;*.=info;\ *.=notice;*.=warn /dev/tty12 And I've got nice log output on /dev/tty12 but where is configuration for log output on /dev/tty8. How can I change it?

• Viewpoint gem and Exchange resource account

  - by scott.simpson

  Hi- I'm trying my hand at using the Viewpoint gem (by zenchild @ github) as the base for a meeting scheduling system. It's great at reading calendar information from regular Exchange 2007 accounts, but I got stuck trying to change the SOAP request header to allow me to read resource accounts as a delegate. I came across http://blogs.msdn.com/b/mstehle/archive/2009/06/16/exchange-api-team-blog-exchange-impersonation-vs-delegate-access.aspx and it seems to be what I need, and I have the feeling I'm on the edge of getting it working, but I'm just not quite there yet as a ruby programmer. Any help would be appreciated... Thanks!

• Split internal USB pinouts - is it possible?

  - by TM

  I've currently got a situation in my PC where I have 3 devices that connect to the motherboard via the onboard USB pinouts. The problem is, I only have two sets of USB pinouts on my motherboard. Is there any way of connecting two devices to one set of pinouts? Essentially, I'm looking for the functionality of a USB hub, but I'd like it to be inside the case, and provide pinouts rather than regular USB ports. Update: I don't need any more USB ports, I have devices that use the USB pinouts. I already have extra USB ports that aren't used, so adding an PCI USB card doesn't really help anything.

• Windows Event Viewer - XML Custom Filter

  - by Frank

  <QueryList> <Query Id="0" Path="Application"> <Select Path="Application"> *[EventData[Data and (Data="Error")]] </Select> </Query> </QueryList> I believe the above XML custom filter would work if I wanted to check for Events where "Data" equals the word "Error". However, what I want to express is that I want the Events where Data CONTAINS the word "Error" . . . how do I express that? I've Goggled around, but I can find no references to Regular Expression like pattern matching in the Event Viewer. XPath has "contains", but if Event Viewer will support it, I cannot seem to figure out the syntax for invoking it.

• Eclipse: open file in external editor only temporarily

  - by user54690

  Using Eclipse, I can open a Java source file with an external editor by right-clicking on the file name (in the Package Explorer) and selecting Open With ... - emacsclient. I'm very glad to be able to do that. However, I only want to do that sometimes, not every time. Now, when I double-click on that same file name, I always automatically get the file opened in emacsclient. This is particularly annoying when I use the Open Type dialog to find a file, because in that case it's not possible to right-click and choose the default Eclipse editor. Is there a way to make Eclipse forget that I previously opened a particular file with emacsclient, so that it can go back to the default behavior of using the regular Eclipse editor?

• How can I bulk rename files in a RAR or ZIP archive on the mac?

  - by Chris R

  I have a set of archive files -- both zip and rar formats -- inside of which I need to rename some files. Specifically, I want to do something like this: for each archive file in a directory for each file in the archive if the file name matches the regular expression /(.* - [0-9]{2})([0-9]{2} - .)*/ rename the file as \1-\2 The trick isn't so much in the generation of the new name; I can do that with either bash or sed or anything else. It's the set of commands to manipulate the files in the archives using rar/unrar or unzip/zip (If it makes a difference, I'm re-formatting some CBR/CBZ files to get the double-page spreads to come up in the right order in SimpleComic -- it interprets page 0203 as page 203, which makes the story a bit hard to follow)

• Installing Linux from External Card Reader

  - by Subhamoy Sengupta

  I have this problem. I was experimenting if I could use a memory card (SDHC) as an USB drive for all intents and purposes, and when I put the card in an USB card reader, I can use it just like regular USB stick and it also shows up in the BBS popup menu as an USB stick. When I tried to create an installation media out of it like this: sudo dd if=/path/to/image of=/dev/sdb And tried to boot from it, simply nothing happened. Cursor blinked a couple times, and jumped to the GRUB of my pre-existing GNU/Linux installation. What am I missing here? Is this not doable? I tried this with Xubuntu 12.04 and ArchLinux, by the way. I have also tried UNetBootIn instead of dd. Nothing happened differently.

• How to remove line breaks (or carriage returns) only from certain parts of a block of text?

  - by Luke Allen

  Whenever I copy formatted text from a PDF file which is formatted to have line breaks (or carriage returns), I need to find a way to remove these line breaks without removing the paragraph format. To do this I need to use RegEx (Regular expressions) to only remove the line breaks which aren't preceded by a period. So for example, if a string of text has a line break right after a period, that is obviously almost always a legitimate line break which will start a new paragraph. If a string of text has a line break mid-word or after a word with no period, it's simply part of the bad formatting I need to get rid of. My problem is that I don't know how to use RegEx to make it only remove the ^p tags in word or CRLF or line breaks in any format under the conditions that it omits ones following a period.

• Server 2008 Task Scheduler and a CMD file

  - by Mark Smith

  Task Scheduler - I have a .cmd file I'm trying to execute on a regular basis through Task Scheduler. I've set the task so that it points to the cmd file. I want the task to execute even when no one is logged in. I've set the credentials associated with the task to the local service account. When I execute the task, nothing happens. The Last Run Result shows 0x1, this means it didn't execute properly. When I run the file from a command prompt it executes just fine. Any help out there would be appreciated. I would post the code but it has sensitive information in it and I'm not allowed to let the code outside. Thanks

• My windows xp wireless hotspot isn't working

  - by Dominic Grenier

  I add the hotspot the regular way. Yet it doesn't show up as available when I try to connect to it using my other Ubuntu laptop. And nothing can connect to it. Yesterday, I successfully made it work for 5 minutes and then it stopped without me changing any configuration. I've already tryed resetting the DNS. Edit: I've updated my Broadcom 802.11b/g driver to a generic but more recent version. I've also repaired the WMI, now the advanced tab of my primary connection is available and the hand meaning the connection is shared appeared. But the computers still connect the wrong way around. (Windows to ubuntu instead of ubuntu to windows) Reinstalled SP3...

• What is wrong with my expect script?

  - by Bryan

  I'm trying to learn how to use the expect command, to help me automate deployment of some software via shell scripts, and figured I start with something simple to get me started. I've created a file in my home dir called 'foo' using: touch foo And I've created the following script saved as test.exp #!/usr/bin/expect spawn rm -i foo expect "rm: remove regular empty file `foo'?" send "y\r" When I run the script using ./test.exp, it spawns the rm command, but it doesn't appear to send the Y and carriage return. I know I don't have a typo in the expect string, as I've used copy and paste to put in the script. What am I doing wrong?

• NFSv4 - ACLs not working

  - by alex

  I've setup an NFSv4 server (Debian) and client (Ubuntu/Mythbuntu). It seems that uid username mapping is working nicely out-of-the-box (I get correct usernames on ls -l if the usernames match between the two boxes, even if the uids don't), but ACLs are not working. I've installed nfs4-acl-tools and I can read the ACLs correctly on the client, but they don't get applied. What needs to be done for ACLs to work? To clarify; username mapping works for regular permissions. ACLs are applied using uid/gid (I can even set ACLs by uid and they work).

• Microsoft Ergonomic Keyboards With Card Readers?

  - by Steve

  When I started working at my current job I developed tendinitis in my wrists. Luckily that cleared up when I started using a Microsoft ergonomic keyboard. The problem is that where I work is moving to more security. We will need to stick a card into a slot to log into our PCs. They bought a bunch of new keyboards with these slots built in. All regular keyboards. Is there something like the Microsoft Ergonomic keyboard that comes with such a card slot? Thanks.

• Do I have to chmod 777 my NFS folder when I share?

  - by luckytaxi

  Under Redhat, if I export a folder as an NFS mount, does the folder have to have RW for users/groups/others? Right now /storage/software is -rwxr-xr-x root/root i.e. /etc/exportfs /storage/software *(rw,sync) On my client, I can mount but I can't write. I'm using a regular user and NOT root. I think "no_root_squash" fixes it but I really don't want that. Then again, nor do I want to have to chmod 777 the folder on the server.

• Using wget to recursively download whole FTP directories

  - by user9406

  I want to copy all of the files and folders from one host to another. The files on the old host sit at /var/www/html and I only have FTP access to that server, and I can't TAR all the files. Regular connection to the old host through FTP brings me to the /home/admin folder. I tried running the following command form my new server: wget -r ftp://username:[email protected] But all I get is a made up index.html file. What the right syntax for using wget recursively over FTP?

• rkhunter warns of inode change by no file modification date changes

  - by Nicholas Tolley Cottrell

  I have several systems running Centos 6 with rkhunter installed. I have a daily cron running rkhunter and reporting back via email. I very often get reports like: ---------------------- Start Rootkit Hunter Scan ---------------------- Warning: The file properties have changed: File: /sbin/fsck Current inode: 6029384 Stored inode: 6029326 Warning: The file properties have changed: File: /sbin/ip Current inode: 6029506 Stored inode: 6029343 Warning: The file properties have changed: File: /sbin/nologin Current inode: 6029443 Stored inode: 6029531 Warning: The file properties have changed: File: /bin/dmesg Current inode: 13369362 Stored inode: 13369366 From what I understand, rkhunter will usually report a changed hash and/or modification date on the scanned files to, so this leads me to think that there is no real change. My question: is there some other activity on the machine that could make the inode change (running ext4) or is this really yum making regular (~ once a week) changes to these files as part of normal security updates?

• failure daemon and changing pid number

  - by Alessandra Bilardi

  proftpd, sshd and apache processes run with /etc/init.d/its-script on linux distro. I was monitoring 21, 22 and 80 ports with farm monitoring service: every 5 minutes service check each port and notify only failure. The failures were 5-6 times on 24h. It seems that someone kicks the switch sometimes.. I add monit and collectd monitoring and the monitoring about 21, 22 and 80 ports is every 1 minute. I do not receive farm monitoring service notify. I receive only monit notify about failure and/or succeed/changing pid number of proftpd, sshd or apache process. The failures are still 5-6 times on 24h. collectd monitoing about cpu, load average and each process is regular and there are no peaks. There is nothing kicks the switch but there is something which determines failure monitoring. is it a simple interference or is it indicative of some abnormality? What could cause these failures?

• Mongodump on Gridfs is killing the host IOs

  - by Raphael

  I'm trying to make a mongodump from our production mongodb while the production is running. We have three production instances, one regular mongodb, one with very few gb of data on gridfs, one with a larger amount of data on gridfs. All mongodb instances are running in version 2.4.9 on a ubuntu 10.04 virtual server. I use a mongodump command to export the bases to another server. Unfortunately our machines are virtually hosted in a "low performances" datacenter (vmware based) so when I try to export the large gridfs db, the disk IO hits 100% (and 50% of the cpu starts waiting for IO too). This has a very negative impact on the production applicatiosn because db access time is excessively increased, making the applications unusable. I'm looking for a way to regulate the mongodump so the export goes slower but cooler on the hardware ressources allowing better performances for the applications to run. Has anyone had a similar scenario ?

• Write to windows share mounted in Ubuntu

  - by aidan

  I used to mount a windows share in Ubuntu server, with an entry in fstab: //data/SharedFolder /media/SharedFolder/ smbfs user,defaults,credentials=/root/.creds,uid=root,gid=root 0 0 /root/.creds is a text file with three lines, my username, password and domain. Users on the ubuntu server could write to this mount, but then I upgraded to 10.04 and now only root can write. Regular users can still read though. mount currently tells me: //data/SharedFolder on /media/SharedFolder type cifs (rw,mand,noexec,nosuid,nodev) How do I make it world writeable again? Thanks

• root locked out of EC2

  - by Paco

  I was in the process of disabling root logins on an AWS EC2 instance. Right after setting PermitRootLogin no and restarting sshd, I closed the terminal on accident -- before setting up users with sudo privileges. The result is that my key to get into the instance as root does not work (sshd forbids it) and when I log into the instance using my regular user I can't gain root privileges (the root password was never set). The instance is running ubuntu 8.10. Anyone have any idea how can I fix this?

• Objective-C protocol vs inheritance vs extending?

  - by ryanjm.mp

  I have a couple classes that have nearly identical code. Only a string or two is different between them. What I would like to do is to make them "x" from another class that defines those functions and then uses constants or something else to define those strings that are different. I'm not sure if "x" is inheritance or extending or what. That is what I need help with. For example: objectA.m: -(void)helloWorld { NSLog("Hello %@",child.name); } objectBob.m: #define name @"Bob" objectJoe.m #define name @"Joe" (I'm not sure if it's legal to define strings, but this gets the point across) It would be ideal if objectBob.m and objectJoe.m didn't have to even define the methods, just their relationship to objectA.m. Is there any way to do something like this? It is kind of like protocol, except in reverse, I want the "protocol" to actually define the functions. If all else fails I'll just make objectA.m: -(void)helloWorld:(NSString *name) { NSLog("Hello %@",name); } And have the other files call that function (and just #import objectA.m).

• Add custom Virtual Machine icons to VirtualBox

  - by Iszi

  I'd like to use custom icons to better distinguish machines running the same OS from each other, in VirtualBox. is this possible? If so, what file(s) do I need to add/edit? Examples: I've got two Windows 7 VMs. One I use as a sandbox for testing various things, and the other I use for when I need to connect to work (ideally, my personal system - the host machine - never directly connects). I'd like to have perhaps a beaker for the sandbox, and a suitcase for the work machine. I've got two Ubuntu VMs. One is BackTrack Linux, the other is a build I'm using to learn more about the OS. I wouldn't mind keeping the regular icon for the latter, but I'd like to use one of BackTrack's icons or images for the former. I'm running VirtualBox 4.1.6 on Windows 7 x64.
