• Windows 7 black screen after boot animation

  - by t_virus

  This is happening with my windows 7 64-bit install frequently. Today i was trying to install an icon pack. There was already a restore point prior to it so i didn't feel like create one. I replaced the following system files in both system32 and sysWOW64 imageres.dll imagesp1.dll zipfldr.dll and shell32.dll After a reboot i see windows boot animation and then a black screen (with no mouse) I let it like that for 10 minutes and the laptop automatically went to sleep mode. I wake it up and see an error box this error "interactive logon failed to initialize" I close it and i'm left with a black screen again, this time with a mouse though. I tried using automatic system repair. It just tells me to remove any extra hardware (i have none attached atm) System restore finishes successfully but doesn't fix the problem. Safe mode doesn't work either. same black screen after boot animation Can someone help me with this? Also, I'll be grateful anyone can upload those default files (listed above) for both system32 and sysWOW64 from a windows 7 64bit install (no service pack)

• Create taskbar shortcut to website in Window 7

  - by BJ292

  I'd like to create a shortcut to a website in Windows 7 on the taskbar that is not pinned to the default web browser. Currently if I drag the favicon from the left end of the firefox address bar to the Win 7 taskbar it will pin a shortcut to the firefox browser icon. Similarly if I create a shortcut on the desktop to a website and drag it to the taskbar it will also end up pinned to the firefox icon. The problem with this is to get to that shortcut I have to right click on the firefox icon and then select the pinned shortcut. That is workable for me but I want to do this for a child - so the shortcut needs to be right there on the taskbar as a stand-alone item. There is a workaround that pretty much solves the problem - create a new folder somewhere safe - create the shortcut to the website in the new folder - right click the taskbar and select toolbars - new toolbar - then browse to the folder you created and select it as the new toolbar. The contents of the folder will now appear on the taskbar as shortcuts. You need to drag it from the right hand end of the taskbar into the middle - turn off show titles and show text and make the icon large. I'd call this a 75% solution. Anyone know how to make a web shortcut that looks and operates just like any of the other shortcuts on the taskbar?

• Vim move cursor one character in insert mode without arrow keys

  - by bolov

  This might seem a little too overboard, but I switched to vim and I so happy about the workflow now. I try to discipline myself not to use the arrow keys, as keeping the hands on the alfa-keys all the time is such a big thing when writing. So when I need to navigate I get out of insert mode, move in normal mode and get back in insert mode. There is an exception where this is actually more disrupting: I use clang complete with snippets and super tab which is great. Except every time I get a function auto completed after I fill in the parameters I am left with the cursor before ) so to continue I have to move the cursor one character to the right. As you can imagine this happens very often. The only options I have (as far as I know) are : Escla or ?, and I am not happy about neither of them. The first one makes me hit 3 keys for just a simple 1 character cursor move, the second one makes me move my hand to the arrow keys. A third option would be to map CTRL-L or smth to ?. So what is the best way of doing this? //snippets (clang complete + supertab): foo($`param1`, $`param2`) //after completion: foo(var1, var2|) ^ ^ | | I am here | Need to be here | denotes cursor position

• What needs to be considered when setting up for Linux Development? [closed]

  - by user123586

  I want to set up a box for Linux development. I have a working linux install with the usual toolchain and an IDE. I'm looking for advice on how to approach structuring accounts and folders for development. As the Perl folks say "There's always more than one way to do it." Left to my own devices, I'll come up with several unproductive ways of doing it before figuring out what an experienced Linux programmer would think obvious. I'm not looking for instructions to follow for a specific set of tools or a specific software package. Instead, I'm looking for insight into what decisions need to be made and how to make them, with understanding of the advantages and disadvantages of each individual choice. These are some of the questions that come up: Where to put sources Where to put built object files and libraries where to install what to set in environment variables what compiler flags matter and how do you manage them across several types of builds what configuration entries to make in an IDE how to manage libraries to support multiple environments how to handle different build versions such as debug vs release, or cross platform builds If you are an experienced Linux developer, the answers to these questions may seem trivial and obvious. I'd like to learn to make decisions about these questions that result in as little manual configuration as possible, given some existing sources, a particular IDE, or no IDE at all, a paticular set of development libraries etc. At this point you're probably thinking: Can you be more specific? Sure. But remember that I'm trying to learn how to think about this stuff, not just follow a recipie for a specific set of results. Example: Setup a project that uses CMake for some of its components, autogen.sh followed by configure for others and just configure for a few more: debug builds without an IDE debug builds in NetBeans debug builds in Eclipse debug build in Visual Studio all of the above with release builds for Linux, Mac and Windows. So... **What are your thoughts on an approach that works for all four? Do you have any advice on what to read?**

• Un-do Windows disk convert HFS+

  - by BLAKE

  Last night, a friend asked my to give him a copy of a word document. He handed me an external hard drive and left. I plugged the hard drive into my file server running Windows Server 2003, opened disk management and clicked OK. (I know that in Windows 2003 you need to manually assign a drive letter to external drives.) I then looked at the drive in disk management and it said that it was unallocated space. I called my friend and he said that there was data on the drive, but he used it with his Mac Book. Aperantly when I clicked OK in disk management I converted the from HFS+ file system to something else. Is there any way to undo the disk convert? I immediately removed the drive, so there was no writing to it. Windows did not format the drive, it just converted it. Is the data still there? All the data recovery programs I have are for windows, can they read the Mac file system? I need to get the data back, what can I do?

• Cisco FWSM -> ASA upgrade broke our mail server

  - by Mike Pennington

  We send mail with unicode asian characters to our mail server on the other side of our WAN... immediately after upgrading from a FWSM running 2.3(2) to an ASA5550 running 8.2(5), we saw failures on mail jobs that contained unicode. The symptoms are pretty clear... using the ASA's packet capture utility, we snagged the traffic before and after it left the ASA... access-list PCAP line 1 extended permit tcp any host 192.0.2.25 eq 25 capture pcap_inside type raw-data access-list PCAP buffer 1500000 packet-length 9216 interface inside capture pcap_outside type raw-data access-list PCAP buffer 1500000 packet-length 9216 interface WAN I downloaded the pcaps from the ASA by going to https://<fw_addr>/pcap_inside/pcap and https://<fw_addr>/pcap_outside/pcap... when I looked at them with Wireshark Follow TCP Stream, the inside traffic going into the ASA looks like this EHLO metabike AUTH LOGIN YzFwbUlciXNlck== cZUplCVyXzRw But the same mail leaving the ASA on the outside interface looks like this... EHLO metabike AUTH LOGIN YzFwbUlciXNlck== XXXXXXXXXXXX The XXXX characters are concerning... I fixed the issue by disabling ESMTP inspection: wan-fw1(config)# policy-map global_policy wan-fw1(config-pmap)# class inspection_default wan-fw1(config-pmap-c)# no inspect esmtp wan-fw1(config-pmap-c)# end The $5 question... our old FWSM used SMTP fixup without issues... mail went down at the exact moment that we brought the new ASAs online... what specifically is different about the ASA that it is now breaking this mail? Note: usernames / passwords / app names were changed... don't bother trying to Base64-decode this text.

• Confused with creating an ODBC connection, apparently I have two separate odbcad32.exe files?

  - by Hoser

  Alright, this is my first time working with this so forgive me if I'm a little confusing or vague. I have a server with Windows Server 2008 Standard without Hyper-v (6.0, Build 6002). I'm running a small website off this server and using a Microsoft Access database to store some information coming in through the website. I'm sure the PHP I have written to open the ODBC connection is correct as it has worked for me when I created this website in a testing environment on a laptop. My current issue now is that it seems like I have two different odbcad32.exe's, and one doesn't appear to have a driver for a .accdb file, and only a .mdb file. The other has a driver for both. The first one I speak of has a driver titled 'Driver do Microsoft Access (.mdb)', the second one has a driver titled 'Microsoft Access Driver (.mdb, .accdb)'. I access the first odbcad32.exe by going to C:\Windows\SysWOW64\odbcad32.exe, and then the one that seems to have the driver I need I go to Control Panel-Administrative Tools-Data Sources(ODBC) and simply create a new connection in the System DNS tab. Whenever I make changes to the one that I access through the Control Panel, I see no changes, however if I use the odbcad32.exe file in SysWOW64 I do get some changes in the errors that come back to me. The main difference I noticed is that when I set up an ODBC connection with the Control Panel method it said it simply couldn't find the ODBC connection, but when I made a .mdb connection in the SysWOW64 one (and pointed it to a .accdb file) it says Cannot open database '(unknown)'. It may not be a database that your application recognizes, or the file may be corrupt. Which makes it seem like it is this odbcad32.exe version in SySWOW64 that is being recognized as the 'correct' one. Is there any way to fix this? I've tried to be as thorough as possible but if I've been confusing or left anything out let me know.

• How can I document and automate a system's configuration?

  - by Diomidis Spinellis

  Having a system's configuration represented by its current state is risky, inefficient, and opaque. At some point you may be left with an unsupported system and no upgrade path. Then configuring a new system compatible with the old is a process or trial and error. Furthermore, if at some point the system is damaged the only option is to go back to the most recent full backup, and try to remember what changes followed from that point. Also, the only way to create a system compatible with the original is through a complete dump/restore. Finally, in such a setup there's no way to know how you solved a particular problem; the only thing you can do is to look at the corresponding configuration files and try to guess what you changed to achieve the desired effect. Currently for each system I maintain, I keep a log file where I record all system administration activity, starting from the installation: installation options, added packages, changes in configuration files, updates, problem fixes etc. In theory this allows me to (manually) replay all changes to arrive at the current state, or to unroll an erroneous change by executing the reverse commands. However, this process is also inefficient, error-prone, and relies on human judgment. Another thing I've tried is to put /etc configuration files under version control with git. This helps me document the changes automatically and also apply them on a clean setup. But it's not without problems: git has to run under sudo, passwords and private keys may be stored in the repository, installed packages can't be meaningfully tracked, and git will have a fit if I try to extend this approach to all the system's directories. I've also thought about performing all changes through shell scripts or makefiles, but I think this process will require a lot of effort and will be fragile. Are there some better methods or tools that I'm missing?

• How can I create a macro that acts on a relative reference rather than an absolute reference to cell A1?

  - by Bruce

  I have a master rent statement in an Excel 2007 (macro enabled) spreadsheet that shows all tenants in rows with columns formed by the months. Each tenant then has a separate rent statement sheet like the one below that pulls the data through from the master rent statement and all I do then is to copy the last 4 columns to the right and add them to the right, just renaming the month labelled as ‘rent due’ with the current month and then hiding the previous last 4 columns to the left so that the statement always shows the previous month's activity and the amount due for the current month: I used a macro to speed up the creation of these statements, but then found that in some cases the result was wrong and needed major correction because the macro use absolute references i.e. its starting position was relative to cell A1 whereas some of my rent worksheets commence from a different column and in some cases from a different column and a different row. I have tried recording the macro with 'Use relative references' but when trying to use the macro it only gets part way through its operation before it stops and the message appears: Run time error '1004' Application defined or object defined error with the option to End or Debug or go to Help and then I'm stuck as I don't know how to debug and work in VBA or understand what has gone wrong. I want to record a single macro that always remains relative to the last 'Total Due' column heading (in the sample, it’s cell FF3 but on another worksheet could be cell GA26) and thus enables me regardless of where on the worksheet the rent statement is placed to add through my recorded macro a further four columns with updated dates and a repositioned 'Total Due' summary (in the sample in cells FE23 and FF23). The contents of cells FE23 and FE22 are always the same number of rows from the 'Sample Rent Statement, Service Charge and Sub Total' rows. I've searched on the web and in the help files of Excel 2007 but have been totally stumped by this, so currently I have to re-record a quantity of macros each month to cover all of the permutations of the worksheets in my Excel rent workbook, which is starting to become pointless in terms of saving time. Does someone know a solution to this problem please?!

• Oracle Linux screen freezes during installation

  - by Fearless

  I was installing Oracle Linux 6.4 on a server, and the screen suddenly froze. Here were the previous steps: I put in the disk, clicked install, checked the disk (no errors), did pre-install setup (clock, root password, host+domain name, etc.), configured two 40GB hard drives in a RAID1 array (no swap, 3100mb encrypted raid partitions, ~100mb ext4 partition mounting to /boot, encrypted ext4 RAID device with mounting to /), selected packages, hit continue. The system did its short preinstall processes, then when to the main installation screen with the long status bar. The installer proceeded like always, but around package 250 out of ~1000, the screen suddenly went black with a text cursor in the upper left corner of the screen and the mouse cursor in its previous place. Neither cursor moved and the only thing that triggered a response was a ctrl-alt-delete that rebooted it. I have run this in VMs before without this issue. Memtest hasn't reported anything, and the media check went smoothly. The machine has supported Ubuntu server without issues before. Any ideas? I have tried booting after that, but the grub bootloader tries to find fd0 for some reason (I have no idea why it would search for the floppy disk). UPDATE My server successfully installed, but won't boot up. I think that, for some reason, it is still using the old bootloader from the previous installation. Any ideas on how to fix that?

• How to get a list of Dovecot IMAP users

  - by Colt McCormack

  How do you get a list of users for a dovecot email server that connect via IMAP (as opposed to POP)? Our server is setup to authenticate via LDAP/PAM. Is there an easy way to get a list of the users who are accessing their mail via IMAP, rather than POP? I am about to migrate our server to Google Apps and want to migrate all of the mail for my IMAP users only (couple hundred out of several hundred total users). POP mail will be migrated separately from the client end obviously. I would much rather migrate only the IMAP users rather than the whole domain which would include migrating a bunch of POP mail left in the server that has already been read/sorted/deleted in the client's email program. Migrating all of that extra useless leftover POP mail could waste weeks of migration time. I suppose parsing some logs to see who has connected on an IMAP port (995 or 993) would give me a list would work if someone could help me do that. I know I have the raw dovecot logs, but am hoping for a cleaner solution.

• How do I know if I managed to completely remove an undetected trojan?

  - by ubuntuisbetter

  I catched a trojan that uses explorer.exe to reproduce itself in case of deletion of its autostart entry or main exe file in Programs/x. It had already tried to contact a suspicious server over explorer.exe, blocked that via my firewall. I: Removed the autostart entries from the registry Looked through my services if there was anything suspicious Deleted the trojan from Programs/ Went through System Volume Information to find a 2 month old explorer.exe and replaced the possibly infected one. There are no suspicious processes running now anymore (no duplicate explorer.exe) and nothing wants to connect this trojan owners sever either. I checked my system with several anti-malware programs too. What the trojan did: Started a second explorer.exe Always when I deleted the main trojan exe file it was reproduced (by the second explorer.exe) Always when I deleted the autostart entry it was reproduced by the explorer.exe too. When I terminated the suspicious explorer.exe, which used only half as much memory as the less suspicious one from Windows, a strange thing that I know from the computers in my Informatics class happened: A window popped up in the top left of my explorer-less desktop, titled "Personal settings for ... are ..." that obviously copied some files. Then both explorer.exes started again and the trojan was everywhere again. What did the trojan actually do to get explorer to rescue it? Is my PC clean of this newish trojan now? What are the other locations I should check for the trojan? The trjoan doesn't seem very high-level, could it have changed other system files or is the autostart entry vital for it? Thanks in advance, Your trojan paranoid friend (Getting linux in a week)

• Did Adobe Photoshop just killed my Graphics Card for good?

  - by user6004

  I was working with Adobe Photoshop, just some regular work, when I came to edit a PSD file and change the text of some layer, when all of a sudden the PC froze. No mouse, screen is frozen, keyboard strokes aren't getting me anything, no Task Manager, nada. So I rebooted my PC, and then something quite terrifying appeared before my eyes. It was not the Checkdisk utility that was launched, that made me terrified (by the way, that reboot damaged the partition table of an external HDD that was connected at the time to my PC, but that's another story). It was the screen itself. Please have a look. So after Checkdisk finished and Windows loaded, I noticed that the resolution was not right. Instead of 1440x900 which I had set, it was 1280x1024. When I went to change it back, I had no option to change back to my old resolution, and has only 3 other general resolution properties, as if my Video Card (GeForce 8800 GTS btw) was not recognized. And what do you know, in the Device Manager it appeared with an exclamation mark. Inside the hardware, it said this: Windows has stopped this device because it has reported problems. (Code 43) Uninstalling the drivers, downloading the newest drivers from NVIDIA and installing them did not work. It always comes back to this. So, do you have any advice before I go out and buy a new graphics card? I thought this was the only option left, but maybe the experts at Super User can help me out. By the way, the dotted screen appears after every reboot, and I see the dots when the ASUS Motherboard screen shows up at boot. Thanks in advance.

• 4GB Memory Upgrade for Acer Aspire 5102WLMi

  - by Richard Slater

  I have bought a 4GB memory upgrade (2x 2GB PC2-5300 SODIMM) for my Acer Aspire 5102WLMi (Aspire 5100 Series) laptop, I installed the two memory modules correctly however with 4GB installed the laptop refuses to POST. I have tried the following: Tried both 2GB SODIMMs without the other (Worked Fine) Tried the original 512MB SODIMMs (Worked Fine) Tried with original 512MB SODIMM and new 2GB SODIMM (Worked Fine) Tried swapping over the 2GB SODIMs (Didn't Boot) Left the computer for 10 minutes with both 2GB SODIMMs installed (Didn't Boot) Checked latest BIOS installed (No Change) The Crucial website said that the laptop supported 4GB of RAM as do several other sites through found through Google, up until now I was fairly confident this would work. Couple of questions that would be good to have answered: Question: Has anyone got an Acer Aspire 5100 Series running with 4GB RAM? Answer: Yes, I have now got one working with 3.75GB Usable, the rest is occupied utilized by the Graphics Card. Question: Any tips on getting this to work; is there a CMOS reset switch? Answer: Yes there is, if both SODIMMs are removed two very small interlocking PCB tracks are revealed. If these are shorted together with a screwdriver the BIOS will be reset. Thanks.

• Bootable ISO to USB stick xp quickest method

  - by brux

  My dog took a leak on my PC when I went out (ye funny), now it reandomly restarts - I'm convinced the HDD is failing because the Windows seagate diagnostic program fails on a few tests. I want to run this prior to windows in an attempt to try and recover sectors, the program includes an iso which can be written to cd and booted, but i dont have any cd's. I tried using unetbootin to create the bootable usb from the iso file (SeaToolsDOS222ALL.576.ISO) but it doesnt work. When i boot from the usb hdd unetbootin loads with "default" in the menu. No joy booting though. I checked the usb hdd in windows and all the files are there, extracted from the iso file, wont boot though. Any ideas? Im using windows xp. More info - when the computer restarts (like i just did now) it constantly reaches the end of POST and then restarts in infinite loop. If I pull the power cable out it will get back into windows, the longer i leave it between attempts, the longer I am able to stay in windows until it restarts. i.e if i leave the power cable out 5 minutes it will stay operable for longer than if i had left it out for only a few seconds.

• How to delete a residual Ubuntu directory from Windows?

  - by memo1288

  I'm using Windows 7. After installing (and uninstalling) Ubuntu on my laptop, I found that it left a folder called ".Trash-1000" on my H drive. I cannot remove it: if I try to delete it from Explorer, it says: The file name you specified is not valid or too long. Specify a different file name. If I try to remove it from the command line, this is what happens: H:\>rmdir .Trash-1000 /S /Q .Trash-1000\files\Screenshot from 2013-09-24 11:57:32.png - The filename, direct ory name, or volume label syntax is incorrect. .Trash-1000\files\Screenshot from 2013-09-24 12:03:45.2.png - The filename, dire ctory name, or volume label syntax is incorrect. .Trash-1000\info\Screenshot from 2013-09-24 11:57:32.png.trashinfo - The filenam e, directory name, or volume label syntax is incorrect. .Trash-1000\info\Screenshot from 2013-09-24 12:03:45.2.png.trashinfo - The filen ame, directory name, or volume label syntax is incorrect. The files mentioned there are the contents of that folder. Using quotes around the folder name yields the same result. Trying to delete any of the sub-folders results in the same error, and trying to remove any of the files inside results in "No such file or directory". As I said before, I no longer have Ubuntu installed. How can I remove this folder?

• Conditional formatting Excel 2007/2010: Highlight the first cell in the row that contains duplicate values?

  - by Nancy Prades

  I have a table with hundreds of columns and rows of data; each row and column have a header. For instance, column headers are ITEM, FILE1, FILE2, FILE3, etc. and row headers are AA, BB, CC, DD, and so on. Under conditional formatting, I used "Highlight Cells Rules" "Equal to", in order to highlight cells that have values equal to the value in another cell. In this case, my formula rule is: Rule: Cell Value = $A$1 Applies to: =$B$3:$G$8 When I input "X" into cell A1, Excel will highlight all of the cells that have a value equal to "X", in this case, the following cells are highlighted: B3, C5, G6, and E8. Here's my problem. The data that I am working with contains more than 100 columns and rows. I want to identify all of the ITEMS (AA, BB, CC, etc.) that contain the duplicate file "X". In order to do this I have to scroll right to left, and up and down. Here's my question. Is there a way to use conditional formatting to add an additional rule? I want to keep the current rule, but I also want the row header to be highlighted if any of the cells in that row contain a value equal to "x". In this case, I want AA, CC, DD, and FF to also be highlighted. Is this possible? I've spent days trying to figure this out - and no luck. Any help would be appreciated! :) Nancy A B C D E F G 1 X 2 ITEM FILE1 FILE2 FILE3 FILE4 FILE5 FILE 6 3 AA x t y u d w 4 BB r y a b k d 5 CC y x f u i g 6 DD t v b d f x 7 EE e w y s l n 8 FF w u n x e m

• Locate devices within a building

  - by ams0

  The situation: Our company is spread between two floors in a building. Every employee has a laptop (macbook Air or MacbookPro) and an iPhone. We have static DHCP mappings and DNS resolution so every mobile gets a name like employeeiphone.example.com, every macbook air gets a employeelaptop.example.com and every macbook pro gets a employeelaptop.example.com on the Ethernet interface (the wifi gets a dynamic IP from a small range dedicated for the purpose). We know each and every MAC address of phones and laptops, since we do DHCP static mapping (ISC DHCP server runs on linux). At each floor we have a Netgear stack of two switches, connected via 10GB fiber to each other. No VLANs so far. At every floor there are 4 Airport Extreme making a single SSID network with WPA2 authentication. The request: Our CTO wants to know who is present at which floor. My solution (so far): Every switch contains an table listing MAC address and originating port. On each switch stack, all the MAC addresses coming from the other floor are listed as coming on port 48 (the fiber link). So I came up with: 1) Get the table from each switch via SNMP 2) Filter out the ones associated with port 48 3) Grep dhcpd.conf, removing all entries not *laptop and not *iphone 4) Match the two lists for each switch, output in JSON or XML 5) present the results on a dashboard for all to see I wrote it in bash with a lot of awk and sed, it kinda works but I always have for some reason stale entries in the switch lookup tables, making it unreliable; some people may have put their laptop to sleep, their iphones drop connections after a while, if not woken up and so on..I searched left and right, we are prepared to spend a little on the project too (RFIDs?), does anybody do something similar? I can provide with the script if needed (although it's really specific to our switches and naming scheme). Thanks! p.s. perhaps is this a question for stackoverflow? please move if it so.

• vim: mapping <control-j> key

  - by bhh1988

  When I'm in insert mode, I sometimes want to be able to move around without using the arrow keys, and without having to go back into normal mode. So in my vimrc I've set up key bindings to do this: imap <C-l> <right> imap <C-h> <left> imap <C-k> <up> imap <C-j> <down> But for some odd reason the only one that doesn't work is the last one, . Doing this in insert mode just gives no response. I'm wondering why this might be, and I just don't know where to even begin looking for the problem. It doesn't appear to be mapped to anything since nothing happens when I do it, whether I'm in the terminal or in gvim. Any pointers would be great! Thanks!

• How To Completely Move Users/Program Files/Program Files (x86)/ProgramData (Folders) To Another Partition(s) On Windows 8?

  - by Enigma83

  I am attempting to move folders Users Program Files Program Files (x86), ProgramData (at the root of the C drive) to at least 2 other partitions, preferably on a fresh install. I have read that there are methods for doing this post-install, but it seems like it would be a bit more tedious to do things that way. I want to move the 2 Program Files folders to another partition on the same HDD, and Users/ProgramData will go to yet another partition on same HDD. I have done a bit of research on this, read up on some things that involved booting into Audit Mode, using the RoboCopy command to copy folders via booting into my Windows 8 USB drive, creating NTFS junctions/symbolic links, Registry edits, as well as accomplishing this automatically by creating an auto-attend file which Windows Setup processes automatically before the user is ever booted in for the 1st time. I tried this morning and now have a basic installation in which programs like Internet Explorer fail to open, certain files can't be found/opened (even if I click on them directly), an example is Regedit. Also, I can't run the Command/DOS (CMD) prompt as Administrator (or otherwise, as any other user), can't activate the real Administrator account or open any of the Administrative Tools (despite having added them to my Start Screen). So far I have only tried RoboCopy-ing Program Files and Program Files (x86) so far, creating junction points for them, and editing the Registry in the relevant locations. This is what I'm left with now. I also found the following blog article which describes how to do this for Windows 7 So, where should I go from here and where can I find more information? And how can this be done without disabling the Metro apps, which I've read will stop working if you move ProgramData. Once I have everything moved, where do I install programs to? Do I tell them to install to C:\Program Files\Program Files (x86) or to the junctioned/symbolic-linked partition/drive? I plan to test in VMware virtual machines from here on until things are working correctly, while using a baseline default install for daily tasks.

• USB Hub vs. Dockinstation USB vs. Laptop USB

  - by Will

  I recently had thougts about my current setup in my office, especially about the UBS ports distribution. Here's my setup: I have a Lenovo T410 docked to a Lenovo Dockingstation Series 3, that providey me with 6 USB ports, which I use all (3 ext. drives, mouse, keyboard, USB Hub of monitor). The USB hub on my ext. monitor (most probably powered by the ext. monitor's power supply) provides me with 2 USB ports, where I use one for my webcam and another for USB sticks. On my T410 itself I have 4 USB slots, that are usually not used, as don't want to mess with USB plugs when undocking my laptop, now and then I plug my printer on one of these, just because I don't have any UBS ports left. Now I'm wondering how fast each of these slots are: I assume that all the 6 USB ports from the dockinstation somehow go through the docking connector on the bottom of my laptop. Does this connector has such a big bandwidth for all these 6 USB ports to perform like if they were dedicated ports as the 4 ones on my laptop? Also how is generally the performance of USB hubs (like the one on my ext. monitor?)?

• SMTP Server setting on Windows 2008 R2

  - by user223298

  I am very very new to this and just trying to configure SMTP virtual server. I have followed a few threads to get it all running, but the mails are not being delivered. What I have done so far - 1) Install SMTP server. 2) SMTP server Properties General Tab - IP address is set to 'All Unassigned'. Access Tab - Authentication is anonymous access. Everything else is left to Default settings. Delivery Tab - Outbound security is anonymous access. In Advance section, entered the domain name in the FQDN field, and localhost in Smart host field. 3) Created an Inbound Rule for SMTP service to allow connections to Port 25. When I try to telnet, everything works up until the point the mail has to be send. Now, the sender's domain is different to the receiver's domain. Not sure if settings have to be changed to allow that? I had set the Relay restrictions on SMTP server, but because I couldn't send the mails, I thought I might as well make it work without the relay first. The error I see while sending the mail is 451 Timeout waiting for client input. I used to get some other error before when I had Relay restrictions on. Can anyone please point me in the right direction? Please let me know if you need more information. Thanks.

• mysql disk io keeps increasing ... is that normal?

  - by trustfundbaby

  So I've been trying to figure out this disk IO problem I have been having with my linode VPS. Over the last day or two I've just left watch -n1 pidstat -d running in a console window and the output looks like this: Monitoring it over the last few days, I've noticed that my problem lies with the init, searchd, and mysql processes. Searchd is sphinx and all its indexes are on disk, so disk io there is inevitable (apparently). What I can't understand is why the disk reads (kB_rd/s) for mysql refuse to stabilize and just keep going up. It started out at 154 yesterday and is up to what you see in that screen shot. but disk writes (kB_wr/s) have remained pretty constant the entire time. My VPS only has 768MB RAM, my mysql db has a size of about 220MB and after running mysqltuner.pl and reading a bit about it, I've been advised to set my innodb_buffer_pool_size to 220MB but I simply cannot afford to do that ... I have it up to 150MB. My question is twofold. Why does the init process have that much disk reading to do? Why is mysql doing so much disk reading?

• Parallel shell loops

  - by brubelsabs

  Hi, I want to process many files and since I've here a bunch of cores I want to do it in parallel: for i in *.myfiles; do do_something $i `derived_params $i` other_params; done I know of a Makefile solution but my commands needs the arguments out of the shell globbing list. What I found is: > function pwait() { > while [ $(jobs -p | wc -l) -ge $1 ]; do > sleep 1 > done > } > To use it, all one has to do is put & after the jobs and a pwait call, the parameter gives the number of parallel processes: > for i in *; do > do_something $i & > pwait 10 > done But this doesn't work very well, e.g. I tried it with e.g. a for loop converting many files but giving me error and left jobs undone. I can't belive that this isn't done yet since the discussion on zsh mailing list is so old by now. So do you know any better?

• What could cause a dual-monitor PC to suddenly stop using one of the screens?

  - by raldi

  I've got a dual-monitor setup using a GeForce 7900GT that was working fine for over a year... then suddenly, only one of the screens works. It's not OS-related, because even on startup, only one screen displays the BIOS checks. In the past, both screens would show it together. I didn't change anything to trigger this The monitor that gets a signal is random -- sometimes the one on the left goes black, sometimes the one on the right. The monitors and their cables are good -- I can switch both or either, and I get a signal just fine. They're plugged in, too. It's not the video card, either -- I have an identical 7900GT in another machine, and swapping the two didn't fix anything. It's not dust on the motherboard -- I pulled everything out, cleaned it off, checked for obvious damage, put it all back together, and no change. My next two steps are going to be to reset the CMOS info and to try swapping out the motherboard. Before I do that, does anyone have any other ideas?
