• What is causing my wireless problems?

  - by user34629

  I have a Dell XPS M1330, since I moved to my new house, the wireless barely works on it, my housemates report no problems, so I guess it's something to do with my laptop. It's eratic in normal mode, sometimes not working for days, usually working on-and-off, forcing me to reload pages a few times before they work, etc. It works perfectly in safe mode, the driver I'm using is the Intel PRO/Wireless 3945ABG Network Connection, version 12.4.4.5, with a date at 26/10/2009, the most recent one I could find, bluetooth is not enabled, and I'm running Vista 32-bit Home Premium, which it shipped with. I also tried disabling IPv6 and resetting the IP stack, both to no avail. Can anybody help me?

• Is it possible to use two different ErrorDocuments for different paths of a website?

  - by tapwater

  this is my first question on stackexchange and it might be a bit confusing. I currently run PmWiki (sorry, you'll have to google it, new user can only have 2 hyperlinks) at mydomain.com/pmwiki. I have a 404 page and .htaccess set up in my site's document root for 404 pages regarding anything that doesn't have to do with my wiki. By default, PmWiki handles URLs a little confusingly so I had to use this in order to get it to look like mydomain.com/pmwiki/Namespace/Page I had to create a .htaccess in /pmwiki to remove parts of the URL. PmWiki also has a custom 404 (Site/PageNotFound) page that has stopped working, now my site uses the /404.htm page. I noticed this when trying to install this "recipe" to enable case-insensitive URLs. Currently the only way to access Site/PageNotFound is by actually linking to it, and, if you read how that recipe seems to function, this is an issue. Currently mydomain.com/pmwiki/blahblah and mydomain.com/pmwiki/legitimate_namespace_but_lowercase/legitimate_lowercase_page_name both direct to mydomain.com/404.htm. I have to admit I'm very confused, and I apologize if I was unclear in any of this, but I could definitely use some help. Thanks!

• Is a memory upgrade a viable option to fix performance issues? [closed]

  - by ratchet freak

  I'm currently seeing my PC getting bogged down by Firefox 11.0 alone with only one hundred tabs open. Resulting in a memory use of over 530M , VM size of over 800M and an insane amount of page faults (easily reaching 100 million over the course of the day). The PF delta during normal operation easily reaches 7k with peaks to 15k sometimes reaching over 20k. This leads to a (real) deterioration to response time when switching, opening and closing tabs, opening menus, typing, ... My question is: Am I right in assuming that plugging in more RAM (either adding 2x1GB or replacing the existing RAM with 2x2GB or 4x1GB) will solve this problem? My specs: Windows XP Home Edition SP3 (32 bit) Intel Core Duo 2,4 GHz 2x512MB RAM 800MHz DDR2 (dual channel) 4MB unified cache 320GB HDD Intel G33 (X3100) onboard graphics (no graphics card but PCI express x16 slot is available)

• Server Sizing Methodology

  - by adbrpc

  Our development environment consist of JBoss 5.0.1 DB Server, SQL Server 2008, Oracle IDM. Hardware is Win 2008 32 bit, 4GB RAM. We have reached stage where our environment can not handle application resulting in JBoss shut down throwing out of memory errors and CPU reaching to 90% usage. I am looking methodology to calculate correct server sizing where I input TPS, max number of concurrent users, max CPU utilization etc.. to give me number of servers, RAM size, number of cores. I am expecting application to grow 10% annually. Load Balancer and Failover should also be taken in account while sizing.

• I use windows7 and am looking for a tool to help me tag/organize my bookmarks as well as my thoughts and projects.

  - by tomcat23

  I've got my bookmarks in Chrome currently, and am prone to just bookmarking something if it contains any info I may need for the project I'm currently working on. I had found a way to tag them with delicious and then get an export from that into a wordpress test server (with the tags), having a post for each bookmark, but this proved to be a bit of a waste of time, as there's no way to organize it well. Ideally I'd like to find some sort of mind-mapper with a Prezi-like view, that does auto tagging, excerpting and allows me to notate things effectively. Does my dream tool even exist? I've usually got 20+ tags open all at once because there may be something open on each I need to see/know to make my current project work. It's frustrating. Though I'm on Win7, I'm interested to hear about any tools that are out there that work to take your existing bookmarks and help you organize them productively.

• Does the .NET Framework need to be reoptimized after upgrading to a new CPU microarchitecture?

  - by Louis

  I believe that the .NET Framework will optimize certain binaries targeting features specific to the machine it's installed on. After changing the CPU from an Intel Nehalem to a Haswell chip, should the optimization be run again manually? If so, what is the process for that? Between generations here are some notable additions: Westmere: AES instruction set Sandy Bridge: Advanced Vector Extensions Ivy Bridge: RdRand (hardware random number generator), F16C (16-bit Floating-point conversion instructions) Haswell: Haswell New Instructions (includes Advanced Vector Extensions 2 (AVX2), gather, BMI1, BMI2, ABM and FMA3 support) So my, albeit naive, thought process was that the optimizations could take advantage of these in general cases. For example, perhaps calls to the Random library could utilize the hardware-RNG on Ivy Bridge and later models.

• Hosting company that does Linux VPS and MS SQL

  - by danielmcq

  I'm looking for hosted solutions but there are so many companies that finding the right one using a Google search is a bit overwhelming. Ideally I would like a hosting company which has following options: -Linux VPSs - Individual VPSs should be fairly cheap since I plan on putting one or two services per VPS i.e web server on one (httpd and ColdFusion), an SVN server on another, etc. -Managed MS SQL databases - My company already has data in MS SQL databases and a lot of ColdFusion code written that has MS SQL specific commands in it. -Individually purchased dedicated IP addresses -Preferably located in the North America region My plan would be to setup one Linux VPS as a gateway/firewall/VPN server and have all of my traffic routed through so that my other servers would not use of bandwidth by talking to each other. The trick is also finding a company that does Linux VPS AND MS SQL databases. Does anybody know of any hosting companies offer what I'm looking for? Let me know if I need to add more details.

• robots.txt file with more restrictive rules for certain user agents

  - by Carson63000

  Hi, I'm a bit vague on the precise syntax of robots.txt, but what I'm trying to achieve is: Tell all user agents not to crawl certain pages Tell certain user agents not to crawl anything (basically, some pages with enormous amounts of data should never be crawled; and some voracious but useless search engines, e.g. Cuil, should never crawl anything) If I do something like this: User-agent: * Disallow: /path/page1.aspx Disallow: /path/page2.aspx Disallow: /path/page3.aspx User-agent: twiceler Disallow: / ..will it flow through as expected, with all user agents matching the first rule and skipping page1, page2 and page3; and twiceler matching the second rule and skipping everything?

• Should I bother upgrading my Opteron 270 Server?

  - by MousePad

  I have an Opteron Server machine (in a large workstation class case) running on the Tyan 2895 motherboard. It's a dual CPU socket board, but I only have one 270 in there. I have 4GB of RAM, but less than 3GB is addressable, even in 64bit mode, due to the way the board is designed. Is it worth spending a few hundred on an additional CPU and maybe some more RAM? The other problem is that one of the two SATA ports on the board had its wire socket break off. So only one drive can be run as of now. I could have it repaired, but at what cost? Add in the fact that the power supply is gunked up with dust and it's a bit of a nightmare. I actually work about it getting too hot. Seems that for the money I could buy a new server rack from Dell, but it also seems a shame to waste an otherwise working, and for my needs still very fast machine.

• Mouse pointer size inconsistent

  - by charon00

  Since installing Ubuntu 12.04, I've been having a problem with the mouse pointer size. On the desktop, it is quite a bit larger than it should be (24), though the different cursors (editing text, hyperlink hand, etc) are correct. The size changes to the correct size when the pointer is over some application windows (GVim, Netbeans, Firefox), but then changes back once it is moved out of the window. There was a similar question here, but the Xdefaults solution did not work for me, and I didn't want to try the one requiring editing the icon image. In addition, I've tried changing the cursor theme using sudo update-alternatives --config x-cursor-theme as well as using the dconf-editor, but though I can change the theme, the size issue remains. In case it's relevant, I'm running on a dual-screen setup with monitor sizes of 2560x1600 and 1920x1080, using the NVidia video driver. Is there another way to control pointer size, or a setting that might be messing it up? EDIT: These are the values/options I have for update-alternatives and in dconf-editor. I'm now wondering if Netbeans and Firefox are making the mouse pointer smaller than it should be, but I'm not sure how big 24 should be... update-alternatives: Selection Path Priority Status ------------------------------------------------------------ 0 /usr/share/icons/DMZ-White/cursor.theme 90 auto mode 1 /etc/X11/cursors/core.theme 30 manual mode 2 /etc/X11/cursors/handhelds.theme 20 manual mode 3 /etc/X11/cursors/redglass.theme 20 manual mode 4 /etc/X11/cursors/whiteglass.theme 20 manual mode * 5 /usr/share/icons/DMZ-Black/cursor.theme 30 manual mode 6 /usr/share/icons/DMZ-White/cursor.theme 90 manual mode dconf-editor: I can't post the image since I'm a new user but the cursor-size is set to 24 and the cursor-theme is DMZ-Black.

• vmconvert exchange 2007

  - by user72950

  Has anyone tried to run vmconvert on a Windows 2008 64 bit server running Exchange 2007? Here is what I did. I stopped the Exchange processes and IIS and ran vmconvert. When I moved the new server to my vmware server 2.0 for windows and booted it. All seemed well except I could not send or receive email. All outbound was stuck in the queues. I was able to log in via OWA so that tells the network setup/NIC bindings were OK. Any ideas?

• What causes Remote Desktop Services Manager to crash in Server 2008 R2?

  - by milkmood

  I have this consistent problem of RDSM crashing in Server 2008 R2. It is either really slow to open, sometimes never opens, or after it's been open and working properly for a bit, stops working, and forces an unload of the snap-in. It's done this since the deployment of this server, new hardware, new instance of S2k8. Domain Administrator login. I am using it to manage 3 Terminal Servers, the other two are S2k3. I've used it without issues on other 2008 servers.

• Is virtual machine slower than the underlying physical machine?

  - by Michal Illich

  This question is quite general, but most specifically I'm interested in knowing if virtual machine running Ubuntu Enterprise Cloud will be any slower than the same physical machine without any virtualization. How much (1%, 5%, 10%)? Did anyone measure performance difference of web server or db server (virtual VS physical)? If it depends on configuration, let's imagine two quad core processors, 12 GB of memory and a bunch of SSD disks, running 64-bit ubuntu enterprise server. On top of that, just 1 virtual machine allowed to use all resources available.

• Workaround broken sudo?

  - by perreal

  I managed to break sudo by deleting the libc.so.6 sym-link in /lib. I copied the actual file and created a symbolic link with the same name under my home directory by using LD_PRELOAD=/lib/libc-2.11.3.so. At this point, all binaries linking libc are working through preload except sudo. For sudo, I need to write (and don't know why): $ /lib/ld-linux-x86-64.so.2 --library-path . /usr/bin/sudo but this gives me: $ sudo: must be setuid root Checking the permissions: $ ls -l /usr/bin/sudo $ -rwsr-xr-x 2 root root 166120 So the setuid bit is actually set. Question: I need to create a symbolic link named /lib/libc.so.6 through my active ssh connection without using sudo, or, make sudo work somehow. I don't have the root password and I can't connect through ssh anymore. Is there any other way I can get authorization?

• Persistent retrying resuming downloads with curl

  - by Svish

  I'm on a mac and have a list of files I would like to download from an ftp server. The connection is a bit buggy so I want it to retry and resume if connection is dropped. I know I can do this with wget, but unfortunately Mac OS X doesn't come with wget. I could install it, but to do that (unless I have missed something) I need to install XCode and MacPorts first, which I would like to avoid. Curl is available though it seems, but I don't know how that works or how to use it really. If I have a list of files in a text file (one full path per line, like ftp://user:pass@server/dir/file1) how can I use curl to download all those files? And can I get curl to never give up? Like, retry infinitely and resume downloads where it left off and such?

• Mount a remote Linux hard drive as another Windows 7 partition during boot?

  - by zhuanyi

  I would like to mount a hard drive on a remote computer (running on CentOS 6) as a Windows drive so that I can install programs to that drive. The primary hard drive for my Windows machine (which is at home) is pretty small, I have a Linux server sitting in a remote data center with a much larger hard drive and allow me to install more stuff. I know most of you are going to say Samba, unfortunately the biggest problem for me in this case is that I can not mount Samba as a network share unless I start OpenVPN or SSH tunneling first, which is not good for my case because I will install some startup programs to the remote drive as well. Therefore, the remote drive has to be ready and work just like another drive BEFORE any of the startup programs start to load. Is that possible? My home PC has Windows 7 Professional 32 bit installed and the remote server is a Xen virtual server running on CentOS 6. I have admin/root permissions for both. Thanks a lot!

• Mix content warning on ASPX page

  - by Amit

  Hi, We have started receiving the mixed content warning on ASPX pages on our secured site. We do not have any mix content, we load all our JS, Images, CSS and ASPX files using HTTPS. I dont know why we have started receiving these warnings now. The latest thing which we have added is the third party control for Dialog boxes from Essential Object. We are previously using their Menu control but added dialog box recently. Also we have made our application browser compatible. I feel the reason is something between these two points. Can anyone suggest any solution or any workaround if they know any or have used Essential Object controls and faced simililar issue? Essential object is saying it is not their problem. The mix content warning appears any time and not specifically when the Essential Control dialog box popsup, thats why I am bit confused. Any help is highly appriciated. Thanks.

• VBA: Parse preceding numbers from string

  - by buttonsrtoys

  I need to parse into two substrings a string that always starts with numeric text followed by alphnumeric text. The strings can vary a bit, but not too much. Below are examples of incoming format and the strings I need: "00 10 50 Information to Bidders" ==> "00 10 50", "Information to Bidders" "001050 Information to Bidders" ==> "001050", "Information to Bidders" "00 10 50 - Information to Bidders" ==> "00 10 50", "Information to Bidders" "001050 -- Information to Bidders" ==> "001050", "Information to Bidders" I was hoping it would only be a half dozen lines of VBA, but my code is turning into a loop where I'm testing every character in the string to see where the changeover from numeric-only to non-numeric, then parsing the string based on the changeover location. Not a big deal, but messier than I was hoping for. Are there VBA functions that would eliminate the need to iterate through each string character?

• WINAPI window management question

  - by gekod

  I'm learning to develop windows applications using WINAPI and plain C. Now I got a bit confused with all those handles and would like to ask if you guys could teach me some good practices to structure and handle controls and windows. Here's where I get confused: Using the IDs declared in the resources for each object, we can get their handles using GetDlgItem(). Now what if we don't know their parent, which is needed by this function. One example: We have the main window created at launch. Then we register two new window classes and create a window for each new class and we create a message function for each too. Now if inside one of the children windows I create a button and inside the other child window I create a text label. Now when we click the button inside of child window A the label in child window B shall be modified to whatever. The WM_COMMAND for the button is interpreted inside the message loop for child window A. Now what would be the best and more elegant way to access the text label inside the child window B? I am in the process of learning the WINAPI and just want to learn it right from the start instead of producing Hacked code that someday becomes unreadable and to later have to adapt to a new way of programing.

• Problems with ATI propietary driver in Ubuntu 12.10, window trail and screen does not update

  - by crystallero

  I have problems with the Ati propietary driver (fglrx). I have an iMac (mid 2011) with a Radeon HD 6900M [1002:6720]. I did not have any problem under Ubuntu 12.04, but since I updated to 12.10, I get some annoying graphic corruption. The worst one is that sometimes the screen does not update with the new information. It happens a lot when I change between tabs in Chrome or Sublime Text. It usually gets updated when I scroll the page. Sometimes, when I type, I have to wait a little bit to view the new characters. And I get trails when I move windows too (like a part of the window). After a while, the trail disappears. I tried to install fglrx, fglrx-updates and the new beta driver downloaded from Ati (12.11 Beta 11/16/2012), with no luck. It happens the same with all of them. I tried to mess with Compiz config, but it didn't fix anything. The open source driver does not suffer this problem, but I need the performance of the propietary driver . Do you have clue? Thanks.

• ripping interlaced video to 60fps (frames per second)

  - by cloneman

  It would appear that Broadcast Television is often 1080i30 (60 fields/s), and non-movie DVDs (example, instructional or TV shows) are 60fields/s as well, at some lower resolution (480i?) However, almost all video that ends up on the internet, whether in x264-encoded content, Youtube, etc. is 30 frames per second, that is to say , it is progressive scan. However, when you watch content on your TV, I'm guessing the TV converts it to progressive for you, but the end result is a very fluid picture that "feels" quite a bit like 60frames/s. What is the best way to obtain this result when ripping interlaced content sourced from TV or DVDs? Can I rip a DVD that is 60 fields per second to 60 frames per second? I would imagine classic deinterlace filters do not do this, they merge fields and create a 30fps output. I'm using handbrake.

  I need a large amount of external storage for an upcoming project. I'm planning on purchasing 10 2TB external drives. I need them all hooked up to a single machine at the same time. What issues will I run into? I plan on using 2 power strips and having them all externally powered from the wall. I will use a USB hub to plug in all the drives. I need drive access time to be as fast as possible. I am using Ubuntu Linux(64 bit). Will I be able to mount 10 drives?

• Automatic repair software

  - by ADOConnection

  Do anyone knows any kind of apps or services for "taking care of servers"? (besides managed servers) There are hundreds of ways your server or application can stop working properly. Small things are easy to miss but usually easy to fix. Log overgrouth, configuration issues, etc. Of course there are best practice checklists, but its not a human task to check configuration best practices. Im sure it can be automated: some kind of agent can monitor all system settings, say what is right and wrong and give suggestions on how to make it right. I have to admin several servers and I need some kind of overview of overall situation. As well as a tool, that will fix problems automatically. Can you people suggest something? (I know its a little bit out of rules of SF, but I think this particular question is quite specific) It would be great to have something like http://stackoverflow.com/questions/1451319/asp-net-mvc-view-engine-comparison but for automation software.
