  • which vista services can be disabled with impunity?

    - by GwenKillerby
    I use Vista on a HP pavilion DV2 laptop. When I look through all the services my laptop starts, it really seems there's way too much of it. I multi boot with XP and 7. Both startup in 40 seconds. Vista takes four minutes. Is there some software that can determine which services I don't need? On 7, there's no propietary HP stuff at all, yet it seems to run fine. Because all these service, there's a LOT of them and some just sit there doing nothing, monitoring for updates I don't really need or want or need to know about the second they're available. my laptop is the only computer i use at home, there's no home network, aside from the modem-router, which is cabled, not wifi. Take for instance Parental controls, and stuff for people with bad eyesight, Tablet PC. I really never use any of that stuff. Hope this question is specific enough. thanks, Gwen.

  • How to choose light version of database system

    - by adopilot
    I am starting one POS (Point of sale) project. Targeting system is going to be written in C# .NET 2 WinForms and as main database server We are going to use MS-SQL Server. As we have a lot of POS devices in chain for one store I will love to have backend local data base system on each POS device. Scenario are following: When main server goes down!! POS application should continue working "off-line" with local database, until connection to main server come up again. Now I am in dilemma which local database is going to be most adoptable for me. Here is some notes for helping me point me in right direction: To be Light "My POS devices art usually old and suffering with performances" To be Free "I have a lot of devices and I do not wont additional cost beside main SQL serer" One day Ill love to try all that port on Mono and Linux OS. Here is what I've researched so far: Simple XML "Light but I am afraid of performance, My main table of items is average of 10K records" SQL-Express "I am afraid that my POS devices is poor with hardware for SQLExpress, and also hard to install on each device and configure" Less known Advantage Database Server have free distribution of offline ADT system. DBF with extended Library,"Respect for good old DBFs but that era is behind Me with clipper and DBFs" MS Access Sqlite "Mostly like for now, but I am afraid how it is going to pair with MS SQL do they have same Data types". I know that in this SO is a lot of subjective data, but at least can someone recommended some others lite database system, or things that I shod most take attention before I choice database.

  • Is SCCM overkill for medium-sized organizations?

    - by Le_Quack
    I am an IT technician in a high school with around 1600 students 250 staff and 800+ client computers mostly running Windows 7. Our team is composed of three members. My boss seems content with a network that works (just about) not necessarily a productive well maintained network that is easy to run and maintain. I'm still fairly early on in my I.T. career so I'm not up to speed on all the different endpoint management solutions that are available. I'm looking for a better way to manage clients (deploy software, track changes, inventory etc) I like the look of SCCM 2012's features but the case studies seem to be aimed at large multi-site infrastructural rather than a single mid sized site. Is SCCM suitable for a mid sized single site or is it aimed at much larger corporations? How can I determine whether or not an endpoint management solution like SCCM is a good fit for our organization? EDIT: Thanks for all the help I'll take a look at SCE and SCCM and get some proposals drawn up to take to my boss/deputy head

  • Script to set "Hide file extensions"

    - by Ickster
    I'm tired of the multi-step process to set my preferred folder options on every server to which I log on (Mostly Win2008, but also some 2012 and Win7 here and there). I'd love to be able to script the process, but unfortunately, I can't find any commands or extensions to do so for folder options. There are several settings I'd like to change, but in particular, I'd like to set "Hide file extensions for known file types" to false. I figure that if I can do that, I'll be able to manage any additional settings on my own. Methods that work on the vanilla command line would be preferred, but if there are commands in PowerShell, I'll use that.

  • ATI Catalyst setting to stretch Windows XP start bar across both displays

    - by scunliffe
    I have a Lenovo T400 laptop with an ATI Mobility Radeon HD 3400 Series video card, using the ATI Catalyst Control Center to span my Windows XP display over the laptop display and a Dell flatpanel LCD. This works fine, but I'm used to NVIDIA multi-desktop that let me control the "Start bar" to either exist on only 1 screen... be duplicated on both, or (what I want), stretched across both. Is this possible with the ATI card/Catalyst Software? If not, are there any utilities out there that will handle this for me? That is, what I have: +----------+ +----------+ | | | | | Lenovo | | Dell | | (primary)| | | +----------+ | | |Start Tray| | | +----------+ +----------+ And this is what I want: +----------+ +----------+ | | | | | Lenovo | | Dell | | (primary)| | | +----------+ +----------+ |Start | | Tray| +----------+ +----------+

  • Is it OK to use WPF assemblies in a web app?

    - by Chris
    I have an ASP.NET MVC 2 app targeting .NET 4 that needs to be able to resize images on the fly and write them to the response. I have code that does this and it works. I am using System.Drawing.dll. However, I want to enhance my code so that not only am I resizing the image, but I am dropping it from 24bpp down to 4bit grayscale. I could not, for the life of me, find code on how to do this with System.Drawing.dll. But I did find a bunch of WPF stuff. This is my working/sample code (runs in LinqPad). // Load the original 24 bit image var bitmapImage = new BitmapImage(); bitmapImage.BeginInit(); bitmapImage.UriSource = new Uri(@"C:\Temp\Resized\18_appa2_015.png", UriKind.Absolute); //bitmapImage.DecodePixelWidth = 600; bitmapImage.EndInit(); // Create the destination image var formatConvertedBitmap = new FormatConvertedBitmap(); formatConvertedBitmap.BeginInit(); formatConvertedBitmap.Source = bitmapImage; formatConvertedBitmap.DestinationFormat = PixelFormats.Gray4; formatConvertedBitmap.EndInit(); // Encode and dump the image to disk var encoder = new PngBitmapEncoder(); encoder.Frames.Add(BitmapFrame.Create(formatConvertedBitmap)); using (var fileStream = File.Create(@"C:\Temp\Resized\18_appa2_015_s2.png")) { encoder.Save(fileStream); } It uses System.Xaml.dll, WindowsBase.dll, PresentationCore.dll, and PresentationFramework.dll. The namespaces used are: System.Windows.Controls, System.Windows.Media, and System.Windows.Media.Imaging. Is there any problem using these namespaces in my web application? It doesn't seem right. If anyone knows how to drop the bit depth without all this WPF stuff (which I barely understand, BTW) I would be thrilled to see that too.

  • How can I set up OpenVPN to accept more than 60 connections?

    - by Robin
    Greetings! We're using OpenVPN and today hit an unexpected connection limit of 60 - even though max-clients is set to the source code default 1024. Server log: Tue Dec 21 13:49:41 2010 MULTI: new incoming connection would exceed maximum number of clients (60) We're slowly adding new clients to the VPN and expect to hit 200 some time next year, if we can get it working. We're running the server on a Win2003 R2. OpenVPN 2.0.9 Server config as follows: local 192.168.10.211 port 1195 proto tcp dev tun dev-node OpenVPN_Vision ca vision_ca.crt cert vision_server.crt key vision_server.key # This file should be kept secret dh vision_dh1024.pem server 192.168.211.0 255.255.255.0 ifconfig-pool-persist vision_ipp.txt ;server-bridge 10.8.0.4 255.255.255.0 10.8.0.50 10.8.0.100 ;client-to-client keepalive 10 120 comp-lzo ;max-clients 100 # Default in source code is 1024 persist-key persist-tun status openvpn-status-vision.log log vision.log verb 3 I would greatly appreciate any help or input on this one. Thanks! Best regards, Robin

  • Office jukebox systems

    - by Jona
    We're looking for a good office jukebox solution where staff can select songs via a web interface to be played over the central set of speakers. Must haves: Web Interface RSS / easy to scrap display of currently playing songs Ability to play mp3s and manage an ordered playlist. Good cataloguing of media. Multiple OSs supported as clients - Windows, Mac, Fedora Linux (will probably be accomplished by virtue of a web interface). We have tried XBMC which worked well as a proof of concept however the web interface is just too immature and has too many bugs for a reliable multi-user solution. I believe the same will be true of boxee. Nice to have: Ability to play music videos onto a monitor Ability to listen to radio streams specifically Shoutcast and the BBC. Ability to run on Linux is a nice to have but windows solutions which worked well would certainly be considered. I am aware of question 61404 and don't believe this to be a duplicate due to the specific requirements.

  • Increase the compression performance of VPN

    - by Martin
    I am currently switching from a system with HPN-SSH tunnels and enabled compression to something VPN based. I have tried tinc and n2n so far, hamachi requires a library I do not have. In my primitive benchmarks I am not satisfied with the achievable bandwidth compared to the SSH tunnels. In tinc the low LZO setting performed best, but compression is only available in UDP mode. Ideally I would like to have a TCP-based VPN with a multi-threaded compression. Can you suggest me some ideas how to increase the performance? Would it be possible to somehow put a compression filter in front of the tun interface? Or are there any VPN implementations that might be better suited for my needs (fast compression, TCP-based, switch mode, does not have to be super-secure)? I would consider tunnelling Ethernet over SSH, but according to some articles it is not advisable.

  • How to synchronize users, passwords, hosts, etc without NIS

    - by joshxdr
    I am administering a very small solaris 2.6 network with 4 boxes total. Is it possible to use scp or similar to replace NIS for synchronizing users, groups, hosts, etc? This network is only a small part of my job and I don't want to spend too much time on it, and I am worried the setup and maintenence of NIS will not pay off. I need it to behave like a proper multi-user system, when a user logs into any machine, the users, passwords, hosts, etc. are always the same. Is there an easy way to do this with scp? Right now I copy /etc/passwd from one box to another with scp, but sometimes I make mistakes or forget a step, and scp inside of shell scripts don't seem to works so well since they require password authentication. Any recommendations would be welcome.

  • using iphone to control mac

    - by Ajay Pandey
    i want to use iPhone touch screen as the touchPad for my mac while both devices are connected via bluetooth. So far i hv gone for two approaches what i want is an application which when launched turns the bluetooth on and get connected to mac.Further ...screen of iPhone becomes the touch pad for mac. i dont want to install anything at the mac like any server........ I have already tried the vnc and remotePad approach. the one with vnc looks more promising for me..but even in that case i have to install a vnc server on mac ,i guess and then we'll have to actually call vnc client while my application is still running,which does not look real in 3.2 verson as it does not support multi tasking. Is there any other way of doing it? or is there anything wrong in my above interpretation? please let me know if there is anyother approach of doing the same or if i can do any thing different with my current approach. hoping for quick response Thanks

  • winkey + arrow key doesn't move windows to 2nd monitor on linux

    - by Berry Tsakala
    in Windows, win+ <-- and win+ --> snap any window to the left/right side of a monitor, and if pressed again, snap the window to the other monitor, in multi-monitor environment. when a window is maximized, it will "restore" the window first, and at the next win+ <-- key the window will snap. this is very easy to use and remember. But on Linux a maximized window is not affected by win+ <-- , and the user must explicitly un-maximize it (win+down. the window is not moved to another monitor a side-snapped window cannot be resized - it behaves like a maximized window. is there another program that behaves like Windows, or I should write one by myself? (i'm using ubuntu/mint)

  • How do I extract files from one tarball to another tarball in one step?

    - by Martin
    I have some fairly large tarball archives, from which I need to extract some files. I will later repack those files to transfer them to another server. Currently that is a two (multi) step process for me: mkdir ttmp tar -vxzf large.tgz -C ttmp/ --strip-components=<INT> <folder-to-be-extracted> or alternatively with wildcards mkdir ttmp tar -vxzf large.tgz -C ttmp/ --strip-components=<INT> \ --wildcards --no-anchored '*pattern*' Then I go ahead and recompress the created folder tar -vczf small.tgz ttmp/* rm -rf ttmp How can I combine these two commands into one? Like this tar -x large.tgz > tar -c small.tgz Just to show, what I already tried: Whenever I search the terms "extract" I will end up here or here or even here. When I use the term "split" I will end up here and that is definitely not what I intend to do. When I use "repack" I end up in strange places.

    Specifically, how can we benefit from these current list of features? We're very new to this and I want to be able to talk intelligently to our IT consultant. VMware Ready Citrix Ready Built-in iSCSI target service Virtual Disk Drive (via iSCSI Initiator) Remote Replication Multi-LUN per Target LUN Mapping & LUN Masking Support SPC-3 Persistent Reservation Support What other products should we compare this QNAP to? I appreciate how informative the site is, but they only seem to sell their products through a small number of channels. Is QNAP well known? TIA!

  • Auditing front end performance on web application

    - by user1018494
    I am currently trying to performance tune the UI of a company web application. The application is only ever going to be accessed by staff, so the speed of the connection between the server and client will always be considerably more than if it was on the internet. I have been using performance auditing tools such as Y Slow! and Google Chrome's profiling tool to try and highlight areas that are worth targeting for investigation. However, these tools are written with the internet in mind. For example, the current suggestions from a Google Chrome audit of the application suggests is as follows: Network Utilization Combine external CSS (Red warning) Combine external JavaScript (Red warning) Enable gzip compression (Red warning) Leverage browser caching (Red warning) Leverage proxy caching (Amber warning) Minimise cookie size (Amber warning) Parallelize downloads across hostnames (Amber warning) Serve static content from a cookieless domain (Amber warning) Web Page Performance Remove unused CSS rules (Amber warning) Use normal CSS property names instead of vendor-prefixed ones (Amber warning) Are any of these bits of advice totally redundant given the connection speed and usage pattern? The users will be using the application frequently throughout the day, so it doesn't matter if the initial hit is large (when they first visit the page and build their cache) so long as a minimal amount of work is done on future page views. For example, is it worth the effort of combining all of our CSS and JavaScript files? It may speed up the initial page view, but how much of a difference will it really make on subsequent page views throughout the working day? I've tried searching for this but all I keep coming up with is the standard internet facing performance advice. Any advice on what to focus my performance tweaking efforts on in this scenario, or other auditing tool recommendations, would be much appreciated.

  • Application that recoginzes default gestures and tells me about results

    - by Andreas
    I need to check what gestures are available for certain touch pads, and also find out what kind of information is available. Is there some kind of application that simply recognizes gestures and prints out all relevant parameters for my test? I am mainly interested in multi-finger gestures, with 2-3 fingers, but also, whether distinctino about where a gesture was done (e. g. right border, left border) would be very helpful. Target is going to be Windows 7 and 8 64 bit.

  • Caching DNS server (bind9.2) CPU usage is so so so high

    - by Gk.
    I have a caching-only dns server which get ~3k queries per second. Here is specs: Xeon dual-core 2,8GHz 4GB of RAM Centos 5x (kernel 2.6.18-164.15.1.el5PAE) bind 9.4.2 rndc status: recursive clients: 666/4900/5000 About 300 new queries (not in cache) per second. Bind always uses 100% on one core on single-thread config. After I recompiled it to multi-thread, it uses nearly 200% on two core :( No iowait, only sys and user. I searched around but didn't see any info about how bind use CPU. Why does it become bottleneck? One more thing, here is RAM usage: cat /proc/meminfo MemTotal: 4147876 kB MemFree: 1863972 kB Buffers: 143632 kB Cached: 372792 kB SwapCached: 0 kB Active: 1916804 kB Inactive: 276056 kB I've set max-cache-size to 0 to make sure bind can use as much RAM as it want, but it always stop at ~2GB. Since every second we got not cached queries so theoretically RAM must be exhausted but it wasn't. Do you have any idea? TIA, -Gk

  • How to define a default tooltip style for all Controls

    - by skjagini
    I would like to define a style with a template when there are validation errors and would display the first error message as a tooltip. It works fine when targeting specific control like DatePicker in the following xaml. <Style TargetType="{x:Type ToolKit:DatePicker}"> <Style.Triggers> <Trigger Property="Validation.HasError" Value="true"> <Setter Property="ToolTip" Value="{Binding RelativeSource={RelativeSource Self}, Path=(Validation.Errors)[0].ErrorContent}"/> </Trigger> </Style.Triggers> </Style> I cannot get it to work for Control though, i.e. the following doesn't give any tooltip <Style TargetType="{x:Type ToolKit:Control}"> <Style.Triggers> <Trigger Property="Validation.HasError" Value="true"> <Setter Property="ToolTip" Value="{Binding RelativeSource={RelativeSource Self}, Path=(Validation.Errors)[0].ErrorContent}"/> </Trigger> </Style.Triggers> </Style> Any idea?

  • rsyslog forward all except ldap

    - by Brian
    I have Centos 6 servers running openLDAP. In the rsyslog.conf, I forward the logs to my central server with this line: *.* @10.10.10.10:514 openldap seems incredibly chatty. I have 3 servers in a multi-master cluster. Those 3 servers generate twice as many logs as my other 80 servers combined. I have been unsuccessful in figuring out how to tell openLDAP to use a sensible log level. (we never specifically set the log level) Since these are my main authentication sources, I'm a bit hesitant to "play around" with them. Is there a way to tell rsyslog to forward everything EXCEPT LOCAL4?

  • How to copy only VM changes in VMware to another physical machine

    - by Paul
    How can I use VMware Workstation to copy only changes to a VM to another physical machine, rather than recopying the entire VM every time? Can I just copy the snapshot files, if the second physical machine starts from a pristine copy of the VM? Would it be best to create a linked clone against the original VM, and then copy the linked clone directory each time? Does that even work? (I'm assuming I'll have to change the path in the VM's metadata file, since the paths will be different. I'm assuming I can't clone a linked clone w/o cloning the base.) Background: I and another developer with VMware Workstation are using VM's for systems development. I have to work from a home desktop. Transporting a multi-gigabyte VM either direction takes several hours at best. Downloading it is easiest, but that takes an hour to get it on a DMZ machine for download and then many hours to actually download.

  • Why can't my networks reach each other?

    - by HOLOGRAPHICpizza
    We have two Buffalo WZR-HP-G300NH2 routers, with the default firmware, DD-WRT v24SP2-MULTI (10/31/11) std - build 17798. Each has a separate cable internet connection with a public static IP address. They are both in the 24.123.68.0/24 space. Both of them can contact pretty much the whole internet, and they can both be accessed out on the internet with no problem, but for some reason they can't talk to each other! When I try to ping one from the other I always get "Destination Host Unreachable". There are no strange routing or firewall rules in place. And they are both set to respond to pings, I can ping them from outside. Our main IT guy is going to call our ISP on Monday, but I'm impatient, so does anyone have any ideas?

  • RandR 1.4 Optimus Dual Monitor

    - by mathepic
    So, I have a dual monitor setup. HDMI comes in through Nvidia, main display is through Intel (I think). I want to use XMonad with the dual setup, and I want to be able to run with or without the second monitor. Is this even doable? I'm using RandR 1.4 and can get both monitors to display something at the same time (by messing with xrandr) but XMonad can never detect more than one rectangle form Xinerama. Does anyone have a working multi-monitor xinerama or twinview configuration that works with optimus/randr 1.4?

  • Favourite Features of VS 2010

    - by Noldorin
    With the general public release of Visual Studio 2010 Beta 2 today, this latest version has created a lot of hype and interest. Indeed, the opinion I've gauged is that VS 2010 has resolved a great deal of the minor flaws left over from previous versions, as well as added some particularly useful new code editor and project development tools (in particular the Premium/Ultimate versions). My question here is: what are you favourite new features in VS 2010 that have really got you excited? Or similarly, what are the flaws of VS 2008 that you are most glad to have resolved? There is a wealth of changes in VS 2010, of course, but these are some of the ones that have interested me most (about which I know!). Integrated support for F# (with multi-targeting for .NET 2.0 - 4.0)/ Much improved WPF designer. The VS 2008 was more than a bit buggy at times. Great improvements to the code editor, such as call hierarchy viewing. A decent add-in framework. A greatly expanded testing framework (now capable of database testing, for example) in Premium/Ultimate. Project planning and modelling features in Premium/Ultimate. If I could request one point/feature per post, I think that would be best, so we could vote them individually.

  • Windows undetectable after interrupted chkdsk

    - by Felthragar
    I have a computer that is running Windows XP. For some reason, the other day it wouldn't start giving me the following message: "ntoskrnl.exe is missing or corrupt" So I put the XP disc in the tray and fired up the repair console and ran the following: chkdsk /r It was on for about eight hours and it got to about 52% I believe. Then there was a power outage and the computer shut down (obviously). Today when I was booting it, it isn't even detecting there's an OS anymore. If I boot the computer with no cd in the tray it says: "Reboot and select a proper Boot device or Insert Boot Media in selected Boot device and press a key" If I run the repair console, or the xp installation program it isn't finding any OS installations. Any ideas on what to do next? Any help is appreciated. Thanks! Update: After turning boot-time diagnostics on, I got this message when booting without cd (instead of the previous one): "Couldn't open drive multi(0)disk(0)rdisk(0)partition(2)"
