• Automating Disk Cleanup on Windows using commandline

  - by Ram

  I asked this question on the MSDN forums but there was no response. Maybe someone might be able to help me out here. I am trying to run Disk Cleanup in the command prompt (and through a C# program) and so I went through all the available options from this link: http://support.microsoft.com/kb/315246 While I am just trying to understand what I can do, it would be good if someone could explain why the drive option /d cannot be set while specifying /sagerun:n Or is it possible, by some way, to run /sagerun for a specific drive? Thanks.

• Significant OS X Finder lag when listing directories/files

  - by Jack Sleight

  I'm experiencing some significant OS X finder lag, that seems to be purely an issue with Finder itself, and not the HD or any other part of OS X (I'll explain below). The lag only appears to be when listing directories/files, where I'm seeing up to twelve or so seconds of lag (the folder opens with a blank list and the spinner going in the bottom right). This happens with both the local SSD and network drives (connected via ethernet or wifi) Browsing both local and network drives in terminal and listing directories is instant I can actually browse files on my NAS from my phone over a 3G connection from the other side of the country faster than Finder can when connected to the local network (madness!) Can anyone help? Thanks.

• Installed 4GB memory but Windows XP 32 bit only reporting 2GB?

  - by AnthonyWJones

  I've just taken an existing XP Pro 32 bit system that had only 0.5GB of memory installed and maxed it out to 4GB. The BIOS reports the 4GB ram however when XP is booted and I look at the computer properties only 2GB of RAM is reported. Can anyone explain this? Before we go up any blind allys the /3GB switch is not the answer here, I have no need for a single process to use more the 2GB of memory. I'm wondering if the the 32 bit XP Pro is deliberately limited to 2GB. I seem to remember seeing an excellent table on a Microsoft site listing all the various SKUs of Windows and what each one was limited to. However I can't seem to find that table now.

• Is there a way to automatically disconnect a notebook from the eletrical power-supply?

  - by Diogo

  I know this looks like weird and useless, but let me explain... I'm running Windows Assessment and Deployment Kit (Windows ADK) to make some tests on Windows 8 Preview. One of it's assessment is the "Battery Run Down Test", which tests battery consumption with some procesor load. I'm trying to "automate" in some way this test, I mean, I wish to execute it without any human intervention (such as manually disconecting the eletric power source to leave my notebook running only from batteries to run this assessment). So, there is some ACPI API, Windows API or even an easy bat shell/VBScript/Powershell command to do this? Does someone already made something like? PS: I'm asking this because I couldn't found any answer, but maybe someone here would have any tip...

• Web Development - How to access custom host, defined in my hosts file, from another device in the same network

  - by Neara

  Ok, I hope i'll be able to explain the issue im experiencing. I'm working on a project, that has 2 parts: one takes all requests from usual localhost, the other handles requests from myhost.local. While trying to access both addresses from my computer, it works ok. But now i need to test myhost.local on mobile devices, connected to the same network. Usually i would just run server from my computer ip in the network: python manage.py runserver 10.0.0.8:8000 And then from any device, going to 10.0.0.8:8000 would show the project im working on. However, now accessing that ip address routes me straight to localhost. So, my question is how to access myhost.local from another device in same network? I don't want to change router settings, if that can be avoided, cos sometimes i work from places where i can't access router admin. Is there any network settings on my computer, that i can change to fix the routing to myhost.local w.o losing access to localhost as well?

• Automatic server redirect that passes through as the referring site

  - by nsearle

  Hey All, As always, I would like to thank all of your help and assistance in advance. I am looking for a way to automatically redirect a user to a site and maintain the redirect site as the referral site. Let me explain the process and what is needed in a step by step format. User clicks on a desired link in an email User is navigated to testdomain.com User is automatically redirected to test.com/landing test.com sees testdomain.com as the referral site Data is gathered via Google Analytics I am unsure as if this PHP code will take care of it, or not - header("Location: http://google.com", true, 303); I could test and that is most likely what I am going to do. But I would like to understand a little more as to WHY this would or WHY this wouldn't work.

• On Mac OS X how can I monitor what is using my internet connection?

  - by Jon Hopkins

  I've got a relatively limited broadband connection (I live miles from the nearest exchange) and from time to time net access (but nothing else) slows to a near crawl. I know from a bit of monitoring software that the connection is being fairly heavily used which would explain it but I don't know what's using it. There are certainly plenty of things which might (these days there are dozens of apps that will either regularly or infrequently check data or download updates) but how can I find out? I'm happy to pay (a small amount of) money if needed, though in that case I'd rather it were a recommendation that me just Googling for something.

• Running "ipconfig /displaydns" in cmd prompt still displays results even after I run "ipconfig /flushdns"

  - by 400_THE_CAT

  Whenever I run "ipconfig /displaydns" I get a long list of sites even after running "/flushdns." I thought my results should be empty considering /flushdns. Is this normal behavior? I also noticed that after I run /flushdns and browse the internet for a couple of hours, my list of cached sites doesn't really change. Google.com, for example isn't on the list but a bunch of sites I've never visited do show up in my DNS cache. Can someone explain this?

• IE and Chrome won't browse the internet on dial up but firefox will. How could I fix it?

  - by Kelbizzle

  First let me say I've done plenty of troubleshooting and will try to explain as clearly and as much as I can. Please bear with me. I have a client's computer who uses dial-up and Windows XP. The problem is when I connect to the dial up ISP. IE or Chrome will not browse the internet. It says page cannot be displayed. but if I use firefox on the dialup connection it works. Sounds simple enough there has got to be something wrong with the proxy settings or something...well, that's what I thought here is the weird part. When connected to the LAN in my office IE, Chrome, and FF all work. I upgraded to ie8 and the issue still happens. How would you go about troubleshooting this issue? What should I do next?

• VPN trace route

  - by Jake

  I am inside an Active Directory (AD) domain and trying to trace route to another AD domain at a remote site, but supposedly connected by VPN in between. the local domain can be accessed at 192.168.3.x and the remote location 192.168.2.x. When I do a tracert, I am suprised to see that the results did not show the intermediate ISP nodes. If I used the public IP of the remote location, then a normal tracert going through every intermediate node would show. 1 <1 ms <1 ms <1 ms 192.168.3.1 2 1 ms <1 ms <1 ms 192.168.3.254 3 7 ms 7 ms 7 ms 212.31.2xx.xx 4 197 ms 201 ms 196 ms 62.6.1.2xx 5 201 ms 201 ms 210 ms vacc27.norwich.vpn-acc.bt.net [62.6.192.87] 6 209 ms 209 ms 209 ms 81.146.xxx.xx 7 209 ms 209 ms 209 ms COMPANYDOMAIN [192.168.2.6] Can someone explain how does this VPN tunnelling works? Does this mean VPN is technically faster than without?

• How to manage a home-grown YUM package repo?

  - by TomOnTime

  There are plenty of websites that explain how to manage a mirror of YUM repos. I want to run a repo for my home-grown packages. Is there a good way to manage such repos? What I need to do: Manage 3 repos: unstable, testing, stable Self-service functions that let users add/remove/promote packages (promote means moving a package unstable?testing or testing-stable). ACLs that control which users/groups may add/remove/promote packages. Automatically re-sign packages as they move repo to repo (since the GPG key for "stable" should be different than "unstable") Automatically run "createrepo" to update repodata when needed. Suggestions?

• How can I copy and paste formatted text in Excel?

  - by Landy

  Before I ask question, I've searched but only found ways of copy and paste "formatted cell". That's not what I need. I want to use an example to explain my requirement: There are 2 cells in a sheet. Cell_A's text is "aaaaabbbbb", and "aaaaa" is green, and "bbbbb" is red. Cell_B's text is "ccccc" and "ccccc" is black. I want to copy and paste "bbbbb" from Cell_A to Cell_B and keep "bbbbb" in red. But in my environment(Office 2007), "bbbbb" is changed to black as "ccccc", the default format of Cell_B. Is there an easy way to implement my requirement?

• Questions about Domains and DNS

  - by ShoX

  Hi, I am totally new to the DNS and server hosting world and not quite sure what I need. I want to get a domain, forward it to my own server, so that the user sees example.com in the url bar and example.com/foo/bar will work. Depending on what subdomain it is, it should do different things (another base-directory at webserver, ftp, etc). Also my email should be able to be sent to and received by that server. What irritates me, is the fact, that in the A-record I can only list IP-addresses and no ports. So do I have to set up a nameserver on my own server? Or do I accomplish this via vhosts on my webserver? I would appreciate any help or link to a tutorial. I know how DNS works, know some basic apache-stuff, etc... so no need to explain that. Thanks

• What's up with IE7's Ctrl-Tab order?

  - by torbengb

  I'm using WinXP + IE7.x at work, and no chance of anything else. From any other Windows application, and Firefox, and whatnot, I'm used to the Ctrl+Tab combination. But IE 7 is really strange... Ctrl+Tab seems to follow no clear sequence, and Shift+Ctrl+Tab doesn't even work, or rather, does the exact same thing, not reverse as expected. Can anyone please explain to me how this key combo works in IE7, because I can't figure it out. Thanks!

• How to solve my black screen at boot?

  - by Juanillo

  I've got a friend with a weird problem. When he starts his computer the screen is completely black until the computer is completely started. So the screen is black until it suddenly shows the Windows desktop. He said that this is happening since a technical service repaired his computer, but that repair is not now in warranty. Recently the computer stopped working, but as the screen is black he cannot access to BIOS or start in safe mode (by pressing F8). When he inserts the Windows Vista DVD the system doesn't boot from DVD (it mustn't be configured in this way in the BIOS). Maybe there´s a problem with the hardware (maybe the graphic card)? Can anyone explain a reason why the screen is black during start-up? Any idea of what to do with the computer to restore it?

• Memory management (segmentation and paging) in 80286 and 80386: How does it work?

  - by Andrew J. Brehm

  I found lots of Web sites and books explaining how memory management worked on the 8086 and later x86 CPUs in Real Mode. I understand, I think, how two 16 bit values, segment address and offset are combined to get a linear 20 bit physical address (shift segment four bits to the left, add offset; segments are 64K and start every 16 bytes). But I couldn't find any good Web sites or books that explained how memory management works in Protected Mode, specifically the differences between 80286 and 80386. Can anyone point me to a good Web site or book (or explain it right here)? (For extra credit, i.e. an upvote, how does it work in Long Mode?)

• Source of Unexplained Requests in Server Logs

  - by Synetech inc.

  Hi, I am baffled by some entries in my server logs, specifically the web-server logs. Other than normal, expected traffic, I have noticed three types of request errors (eg 404, etc.): Broken links, ie links from old, external pages that point to pages that are no longer here Sequences of probes, ie some jerk trying to hack in by scanning my server for a series of exploitable admin type pages and such What appear to be completely random requests for things that have never existed on the server or even have anything to do with the server, and appear by themselves (ie not a series of requests like the probes) Could it somehow be a mistyped URL or IP? That’s about the only thing that I can think of, but still, how could I get a request on say, foobar.dyndns.org (12.34.56.78) for something like www.wantsfly.com/prx2.php or /MNG/LIVE or http://ant.dsabuse.com/abc.php?auth=45V456b09m&strPassword=X%5BMTR__CBZ%40VA&nLoginId=43. (Those are a few actual requests from my logs.) Can someone please explain scenario three to me? Thanks.

• Risk to native OS from Live CD?

  - by Frost Shadow

  Will booting from a Live CD (I was thinking Anonym OS) have any risk to the native OS? I wanted to try it out on my school´s computer, but I´d rather not have to explain why I accidentally reformatted the HD and deleted everything.. I know once you´ve booted the right way, it shouldn´t leave any trace on the HD, but is it possible I can push some wrong button and end up trying to overwrite the native with the Live OS? Also, since the computer itself is connected to the internet, will the network administrator be able to see that i´ve booted from a Live CD? I´m thinking yes, but just thought I´d check. Thanks for any help!

• Using PCIe and onboard together

  - by dave

  I'm currently using my PCI Express card to run 2 monitors and my onboard to run another. It works fine despite people saying it won't. I use a gadget to monitor my PCI card but would also like to monitor my onboard GPU as well. I play a game called Eve Online and when I'm running my accts I can only get 20 fps. Before, when I was using just my PCI card, I was getting 60+. To solve this, I set the display options to interval immediate, it was set to one before. My computer handles it no problem at all, but I was always told this was immpossible. I was hoping someone could explain how and why this is working. Thanks! My setup is: i7 2600k 16 GB RAM XFX HD6970 2GB

• How can I figure out exactly which process is keeping my Mac from going to sleep and waking it up?

  - by pattern86

  I have read this knowledgebase article, but would like to know if there's a way to tell exactly which process is causing my Mac not to follow the sleep schedule I have set in System Preferences Energy Saver. I have narrowed it down to a being a process and will explain why I think so (see below). I am running OS X (10.6.5) on the new iMac 27" and I am certain it's not the following: The "Wake for Network Access" checkbox in Energy Saver settings (has never been a previous issue) Peripherals (has never been a previous issue) Any active GUI application (all are closed) Additional USB/FireWire drives (none are connected) Bluetooth (it's off) Sharing services (has never been a previous issue) The symptoms are as follows: The computer doesn't go to sleep at the predetermined time. It will wake up some number of hours after being put manually to sleep (but not within the first few seconds/minutes.) Is there a specific string I should be looking for in Console? I have tried searching for "wake" and "sleep" but can't make total sense of the results.
