How can I add leading zeros between delimiters in Excel 2010

- by Gregory Biernacki

I am trying to convert a list of property id numbers that has a standard format of 0000-A-00000-00-00, where my worksheet has the various combinations of 1-A-123 10-B-1234 Ideally they would read as follows 0001-A-00123-0000-00 0010-B-01234-0000-00 I've tried using the custom number formatting but it doesn't like the letter in the middle of the number. I didn't know if my only option was to break them apart and then put them back together again. I would accept a solution that merely put the leading zeros at the front of the number, (max is 4 characters) so the result could look like 0001-A-123

Very high memory usage, but not claimed by any process?

- by SharkWipf

While stress-testing LVM on one of our Debian servers, I came across this issue where memory would fill up a lot to the point where it would run the server out of memory, but no process would claim the memory. See http://i.imgur.com/cLn5ZHS.png, and see http://serverfault.com/a/449102/125894 for an explanation on the colors used in htop. Why is this happening? And is there any way to see what process is using the memory? Htop is configured not to hide any processes, so what is it that htop is missing? In this particular case, I can fairly certainly say that it is caused, directly or indirectly, by lvmcreate, lvmremove or dmsetup, as I was stress-testing that. Do note that this question is not about solving the LVM problem, but about why the memory isn't claimed by any process. Stopping all LVM commands does bring the memory back down to <600MB.

Disaster Recovery Example

Previously, I use to work for a small internet company that sells dental plans online. Our primary focus concerning disaster prevention and recovery is on our corporate website and private intranet site. We had a multiphase disaster recovery plan that includes data redundancy, load balancing, and off-site monitoring. Data redundancy is a key aspect of our disaster recovery plan. The first phase of this is to replicate our data to multiple database servers and schedule daily backups of the databases that are stored off site. The next phase is the file replication of data amongst our web servers that are also backed up daily by our collocation. In addition to the files located on the server, files are also stored locally on development machines, and again backed up using version control software. Load balancing is another key aspect of our disaster recovery plan. Load balancing offers many benefits for our system, better performance, load distribution and increased availability. With our servers behind a load balancer our system has the ability to accept multiple requests simultaneously because the load is split between multiple servers. Plus if one server is slow or experiencing a failure the traffic is diverted amongst the other servers connected to the load balancer allowing the server to get back online. The final key to our disaster recovery plan is off-site monitoring that notifies all IT staff of any outages or errors on the main website encountered by the monitor. Messages are sent by email, voicemail, and SMS. According to Disasterrecovery.org, disaster recovery planning is the way companies successfully manage crises with minimal cost and effort and maximum speed compared to others that are forced to make decision out of desperation when disasters occur. In addition Sun Guard stated in 2009 that the first step in disaster recovery planning is to analyze company risks and factor in fixed costs for things like hardware, software, staffing and utilities, as well as indirect costs, such as floor space, power protection, physical and information security, and management. Also availability requirements need to be determined per application and system as well as the strategies for recovery.

Modifying the install environment for RH-like installations

- by javanix

I am trying to modify the basic installation environment (ie, what Anaconda runs in) for a customized CentOS distribution. For the first try, I would just like to modify a few of the splash images. My initial attempt to do this entailed: 1) Mount images/install.img to a directory ~/img/ 2) Copy all files from img/ to ~/tmpimg/ 3) Modify the splash images 4) mkisofs -o ~/final/install.img 5) cp ~/final/install.img back to my ~/cdroot/ folder and remake the iso. However, the generated .img in step 4 doesn't even come close to matching the file size from the original install.img (meaning that install.img must be created in some other fashion using compression), and it fails when I boot my iso. What settings should I be using to make the install.img file? Is there some other technique for modifying CentOS install environments?

How to completely remove MySQL from Windows?

- by Nathan Long

(I realize there are similarly-titled questions, but this one is really 'how do I reset the password', and this one doesn't specify an OS and has only gotten Linux-oriented answers.) On Windows XP, I just uninstalled MySQL and deleted the folder that it was installed in. I then rebooted and reinstalled MySQL. When it comes back up, it still has the databases it had before the uninstall. Where did it keep that database info? How do I completely remove MySQL and start over, as if I'd never installed it?

Precise: Evolution laggy due to IMAP -profile or due to some odd Sync -issue?

- by Izzy

I'm fighting with Evolution. Basically it's working fine -- but it is very slow to react in certain situations. There is apparently some problem with syncing and IMAP. Helper questios Could be that changing away from Bonobo has to do with slowing-down? There might be some trouble with the new engine and "asynchronous actions". What to do about it? I want to get the previous "working mood" back. How can I speed this thing up? Different scenarios when sending a mail, the composer window hangs there inactive for a couple of seconds, everything grayed out. Though there is a green check mark saying it's sent, I'm not sure a) why it's still blocking everything and b) whether I could simply close it without "breaking"/"losing" anything. In earlier versions, the composer window was closing pretty fast, and one could see the message being stored into the local "outbox" until it was sent, and one could immediately continue with the next task. I prefer that behaviour over the current. switching between modules. Coming from mail and switching to the address book takes a couple of seconds. Same for switching to the calendar. I read about different "possible causes" and tried a few things: I only have 3 local address books, so no networking should be involved here. To make sure, I switched to offline mode and then tried to access the address book. No noticeable difference. I use 3 Google Calendars. Switching to offline mode made a minor difference, but so minor that it also could be "imagination" since one might have expected this in this case according to some reports, disabling the tasks should help. Well, it didn't in my case, as I don't use them regularly (just two local items stored here)

How can I get the best performance for playing games?

- by Oli

I've been playing a couple of Wine-games today and decided to switch to metacity to see what the performance difference was like. If you've never done it before, you just run metacity --replace but don't do that if you use Unity! Anyway, surprise surprise it was like playing on a dedicated Windows gaming machine. Playing under metacity today was bliss. Much higher framerates and just a fluidity that you'd expect from a native game. I'm not sure I can go back. Switching to metacity is no hardship but I wonder if there's anything else in the WM landscape that I should try out. I'm essentially looking for suggestions for the best way to play games. Mix up WMs, dedicated X sessions, whatever... As long as it makes Wine games run faster. Small print One process per answer (eg: New X session + OpenBox) We should probably land on a benchmark so we can show percentage improvement over a stock Compiz desktop. I'm open to suggestions in the comments. If people could test it and submit their how much it improves things for them in the comments, that would give others a good idea of if it's worth the pain.

TechEd North America 2012-Day 4 #msTechEd #teched

- by Marco Russo (SQLBI)

I hadn’t time yesterday to write a blog post before of the beginning of the day and I recover now that I’m already back to Europe. I spent many hours at the Microsoft booth meeting people who asked questions about Tabular, Power View and PowerPivot. I have to say that I’m really glad so many people started using PowerPivot and of the large interest around Tabular. During my BISM: Multidimensional vs. Tabular I’ve been helped by Alberto during the demo (we joked about he was the demo monkey) and the feedback received are good. I tried to compare the strength and weakness of the two modeling options without spending time describing the area in which they are similar. During the days before I had many discussions about scenarios based on snapshots and I added a few slides to the presentation in order to cover this area that I thought was marginal but seems to be a very common one. To know more, watch the presentation when it will be available or wait for some article I’ll write in the future describing these patterns. In less than 10 days, I’ll be at TechEd Europe and I’m really looking forward to meet other Tabular developers and PowerPivot users there!

hp laserjet 4200 madness

- by C-dizzle

I have an HP LaserJet 4200 printer that is acting really weird. I can print from internet just fine, no problem... but when I try to print from a document used in microsoft word, for example, I always get "Manual Feed Tray 1". I have racked my brain on this and cannot get it figured out. It's a networked printer and only an administrator account can make changes to it, I have also reset the printer back to factory settings, uninstalled and reinstalled onto the pc's and server it is connected to. Running out of hair since I'm pulling it all out... please help.

Windows Server 2003 guest on Xen frequently stops responding

- by smokris

I'm running a Windows Server 2003 guest instance in Xen 3.x. This DomU runs fine for a day or two, then stops responding — I don't get any network response, and I can no longer connect to Xen's VNC console for this DomU. xm list shows this: Name ID Mem VCPUs State Time(s) Domain-0 0 6508 8 r----- 1161159.4 [A working Linux DomU] 1 512 1 -b---- 68711.1 [The hung Windows DomU] 5 512 1 ------ 67234.2 [Another working Linux DomU] 3 512 1 -b---- 163036.4 (What does the ------ mean? The xm manual explains what each of the six states mean, but not what no-state means.) If I xm destroy and then xm create the Windows DomU again, it boots right back up (with the Windows alert The previous system shutdown at [...] was unexpected.), and then stops responding after another day or two. I checked /var/log/xen/*.log, but no log messages are generated at the time the server stops responding. How should I proceed in troubleshooting this?

Dell PowerEdge 6850 Degraded HDD

- by Matt

Good Morning, We have a dell power edge 6850 with a degraded drive in the RAID array. I have never had to recover such an issue, so any help or advice would be welcome. Basically it hasn't affected the server at an operating system level, but has slowed down performance, I have a replacement drive in hand but as this is our main database server I want to proceed with extreme caution. My options as I see them are - Can I just hot swap the degraded drive with the new one and the data will automatically re-sync and we are all back to normal presumably this is dependant on the current raid configuration? reading various comments on-line I may need to re-configure the RAID array and re-build the broken drive? This screams disaster to me with the main worry being that I wipe any other data. Option 1 would of course make my day. Thanks in advance

MS Outlook Voting mismatch

- by Robert Ilbrink

I did send out an Outlook vote to hundreds of employees, using their email address (which is mostly [email protected], but there are many exceptions). The incoming votes are not matched against the email address, but against the display name. Unfortunately, the display name has no real standard either. So instead of seeing this: [email protected] Voted: Yes [email protected] Voted: No I see this: [email protected] [email protected] Doe, Johnathan Philip Voted: Yes Doe - Peeters, Marian Voted: No In the actual list I see the addresses that I sent the vote to PLUS extra lines with the votes that came back. Is there a quick way to match my "send" list with the "received" list? One thing I thought of was to dump the global address book in a file and in Excel use =vlookup. But that seems a lot of work (and I am not even sure that I have the authorization to dump the address book).

User Switching in XFCE 12.04 with LightDM and dumping unneeccesary Gnome libs

- by user111120

I'm an elder non-techie Mac-to-Linux convert trying to play the linux tech game by ear, so please be gentle! :) I am running XFCE Ubuntu 12.04 totally on a 8-gig flash drive and it's fantastic. I am starting to run into potential space issues (down to 1.0 gig free from 1.9 gigs since being installed last summer), most likely because of growing Thunderbird mail files, and this prompted my question. I just installed lightDM on my system because I want the ability to switch users in XFCE if I follow instructions on another blog. They advised using LightDM instead of GDM because LightDM doesn't download Gnome libraries. That's great since I need the space, but my question is how can I tell whether I don't already have Gnome libraries installed from other updates and such? And can I minimize having any Gnome libraries? The method for me to switch users entails creating a "fast-user-switch" file in /usr/local/bin; is there any easier way? One last thing so I din't have topen another needless thread; while experimenting I somehow lost the share folder in one of my accounts. Is there any way to get a share folder back? Thanks for any tips! Jim in NYC

Repairing a corrupt exFat file system

- by Wandyer

Long story short : I messed up my GPT and went on to try to fix it without asking anyone, just searching around. Didn't turn out too well. Right now all I'm concerned about is a 500GB that I formatted as exFat partition with some important files. But on my journey to fix, I may have used the 'fdisk' command on a GParted Live CD I have (couldn't get on any OS) and switched it to ext2. Now I can't get access to it, doesn't show up on Windows or Mac. Only on the partition table as ext2. I have got access to most of my files through recovery softwares but they cannot recover with the originial directory or file names, which would be a pain to fix. I want to know if there is a way to change back the file system to exFat without having to format it. Thanks in advance. EDIT: This is how my partitions look like right.

What's the difference between a normal ActiveX killbit update and one for IDX?

- by Bob

I'm looking back at some old MS security bulletin for distribution to new clients and when I look at downloads for the last set of MS ActiveX killbits, KB article here, under each platform I see links with the term IDX. For instance there will be an entry that says "For Windows 7 for 32-bit versions" and then one a few rows down that says "For Windows 7 IDX for 32-bit versions". What's the difference between the two? I understand from a little digging that idx is one of the field names for the database that ActiveX controls are stored in, but that's not really helpful.

techniques for displaying vehicle damage

- by norca

I wonder how I can displaying vehicle damage. I am talking about an good way to show damage on screen. Witch kind of model are common in games and what are the benefits of them. What is state of the art? One way i can imagine is to save a set of textures (normal/color/lightmaps, etc) to a state of the car (normal, damage, burnt out) and switch or blending them. But is this really good without changing the model? Another way i was thinking about is preparing animations for different locations on my car, something like damage on the front, on the leftside/rightside or on the back. And start blending the specific animation. But is this working with good textures? Whats about physik engines? Is it usefull to use it for deforming vertexdata? i think losing parts of my car (doors, sirens, weapons) can looks really nice. my game is a kind of rts in a top down view. vehicles are not the really most importend units (its no racing game), but i have quite a lot in. thx for help

How to set up a PC which can be booted from Linux AND Windows?

- by Martin

Our PC was running Windows XP up to know. It has become incredibly slow and I'm considering switching to Linux (Ubuntu?!) as a fresh OS. However, there are some applications we rarely use which run only on Windows and I also want to have the possibility to easily go back to the old system, if I should find during testing linux, that anything is missing or not available. So the idea is to install Linux on a new (second) hard drive and use the existing Windows XP from a virtual machine (converted by Paragon Drive Backup) in the transition time. We have a lot of data on the PC, tens of GBs of Photos (managed by Picasa), ... My questions: What could be the best way to setup the new hard drive? (Partitions) I assume that I can not access the Linux data from Windows but I could access (read/write) windows drives from Linux? Does anyone know good tutorials for this use case? What other things might I have to consider for transition Windows-Linux?

Can Windows XP remember file icon position?

- by g .

Windows allows you to arrange icons however you like in a window. However after some time when I go back to the window, it has forgotten the icon positions and has completely rearranged the icons. Is there a way to preserve the icon positions? In the previous version of Windows I used, this would happen on rare occasions (about 6 months) and it might only move a couple of icons. Now it is happening practically every day and it is every single icon. Attempts to rearrange them manually are futile and it is increasingly maddening. Searching Google, I have found a number of programs that allow you to save and restore icon position on the desktop. But, this is just a regular folder window so I am not sure if any of those would even work. Some details: Windows XP SP 3 running in Parallels 5 virtual machine Auto Arrange and Align to Grid are NOT turned on Fresh OS install and only setting icon positions in one window

Ubuntu on Samsung NP700Z5B - no Grub

- by copolii

I just bought a Samsung NP700Z5B laptop. Gorgeous machine and great performance! I do 2 things when I get a new laptop: Format the HD and install Winblows from a CD to ditch the bloatware Install some variant of Linux on it (lately Ubuntu) Step 1 worked fine (until earlier today), but I haven't been able to install Ubuntu on it for the past 3 days! I've tried Mint12, Ubuntu 12.04, Ubuntu 11.10, Ubuntu 11.04 and Ubuntu 10.04. The live CD and the installations all run fine and report no problems, but when I reboot grub is nowhere to be found! The system goes directly to Winblows! I've tried booting from the liveCD and re-installing grub via the chroot and purge & reinstall methods (https://help.ubuntu.com/community/Grub2) and neither makes a difference. I've also tried copying the boot sector: dd if=/dev/sda of=linux.bin bs=512 count=1 and putting it on c: then setting bcdedit to add the entry to the Windows bootloader with no results. Earlier today I decided to try and set my boot partition as an EFI boot partition ... bad choice, now I don't even have the Winblows boot loader. I've officially ran out of ideas. Tried calling Samsung, but they're closed (they'd probably say something stupid along the lines of "Samsung recommends Windows 7" ... I've had Dell say that to me). Any help would be greatly appreciated. Update 1 Tried re-installing 12.04 and now I get the screen continously turning off and back on, but still no sign of booting ... it has been doing it for 15 mins so far (I set the boot partition type to ext2 instead of ext4) Update 2 Well ... this just gets better and better. I inserted the installation USB key to reboot it and the flickering stopped for about a minute (remained on) then it started turning off and on again

Transfer Raid Drives to External Enclosure

I have 2 raid disks (a grand total of 360GB) in my laptop. I'm fast running out of space and want to install new drives. I've a pretty good idea how to do this. My question is what can I do with the drives that I remove? I've got lots of media files on these drives that I'd like to keep and maybe transfer back onto my laptop once I have the new drives installed. Bearing in mind that I know next to nothing about hardware how do you suggegst I go about reusing the removed drives somehow? Thanks,

Connecting / disconnecting DisplayPort causes crash

- by iGadget

I wanted to file a bug about this using ubuntu-bug xserver-xorg-video-intel, but the system prompted my to try posting here first. So here goes :-) While the situation in Ubuntu 11.10 was still somewhat workable (see UI freezes when disconnecting DisplayPort), in 12.04 (using Unity 3D) it has gotten worse. The weird part is that during the 12.04 beta's, the situation was actually improving! I was able to successfully connect and disconnect a DisplayPort monitor without the system breaking down on me. But now with 12.04 final (with all updates), it's just plain terrible. When I now connect an external monitor using the DisplayPort connector on my HP ProBook 6550b, it only works sometimes. Most times (but not always!) the screen just goes blank and the system seems to crash (not even CTRL+ALT+F1 works anymore). Only a hard shutdown by keeping the power button pressed for several seconds and then a restart gets me out of this. I suspect the chances of the system crashing become higher as the system's uptime increases, especially when there have been one or more suspend-resume cycles (although I have also experienced this bug once from a cold boot). Disconnecting is roughly the same as with 11.10 (see issue mentioned above), with the difference that if I resume from suspend, I no longer have to do a CTRL+ALT+F1, ALT+F7 cycle to get my screen back. So what more can I try? Or should I just go ahead and file the bug anyway?

RDP locks up login, doesn't unlock on Windows

- by private_meta

From time to time, my system, when I try to login TRHOUGH or AFTER a remote connection, locks up the login session. I can't login anymore, the screen turns black (the monitor is still active, the image is black). Especially in the recent case, the system did not come back from the lock-up, and I had to reset the computer. Any idea what might be the issue here? More information: Both Computers are Windows 7, The RDP Server has a wired connection, the Client has either Wireless or Wired. The network card involved on the server is a "Realtek RTL8168C(P)/8111C(P) Family PCI-E Gigabit Ethernet NIC (NDIS 6.20)" card built-in on an ASRock Mainboard. I'm using either local LAN or internet connection through NAT/Router.
