  • What are best practices on virtual lab/test bed architecture?

    - by WooYek
    I am currently preparing a new small virtual environment for development and testing with Windows Server + SQL Server + AD + Sharepoint + Exchange + IIS(ASP.NET) + Biztalk + ?, for a small (up to 5) dev team. What are pros and cons on different approaches, eg. splitting up over different machines or packing everything up per machine. I your experience what are the best practices I should follow in terms of architecture and various system/servers placement. What to share and what to split per person. I would like to achieve some flexibility for the dev and testing process (so teammebers would not be steeping on each other's toes) and limit administrative effort needed to propagate settings, integrate work items and revert changes when something breaks up. It's not supposed to be an everyday development working environment, more a tier 2 developer testing environment, and not yet an integration or QA testing environment with formal change process. IMO the two borderline solutions are: creating one all-inclusive machine for each dev team member giving them freedom to manage creating shared environment managed by the one with somehow formalized change request process What golden mean would you recommend, and why?

  • Archiving mails with postfix: how to filter mails?

    - by Tronic
    i wanto to implement the following scenario: we use a postfix mailserver. to archive all old and new mails, i want to setup a second postfix on our fileserver and create a single mailbox "archive". then every mail gets forwarded as bcc to this mailbox automatically. now, i want to create different folders in a maildir structure and let the server move each mail to the right subfolder of the mailbox based on its sender or receiver. e.g. when we get a mail to one of our employees named "John Doe" at [email protected], the mail should be moved to "Inbox/John Doe Incoming". the same applies when john doe sends a mail, folder would be "Inbox/John Doe Outgoing". how can i implement this filter behaviour. i heard of Procmail and Maildrop. Which of the two would you prefer? Which is more easy to configure? Any out-of-box solutions here? thanks in advance!

  • Silent install FirePro v4900 Driver on Windows Embedded 7 Standard

    - by Birgit_B
    I'm trying to install the Drivers for a FirePro v4900 on a Windows Embedded 7 Standard 64bit OS. I want the system to be as small as possible, so i would rather not install the whole catalyst control center, but only the necessary drivers. Because the installation should be accomplished absolutely unattended, the installation process of the FirePro-Driver should also be done without any user interaction. I see two possible solutions for the Problem: Install only the Drivers: Is it possible to solely install the necessary drivers? How would i achieve that? This solution would be the preferred one, because of the smaller footprint. Silent custom install the provided "FirePro_8.911.3.3_VistaWin7_X32X64_135673.exe" (found at ATI FirePro™ Driver). Is there a way, to do that? Thank you in advance for your support! Update: I managed to accomplish a silent installation. I extracted the contents of the above mention installer-file and ran \$_OUTDIR\Bin64\Setup.exe -Install. (There are some other Parameters, just run Setup.exe /?). But i couldn't achieve to just install the drivers without the Cataclyst Control Center, and it seams the Control Center has some unfulfilled dependencies and so it crashes...

  • Optimal Networking Setup for a 2-Story unit?

    - by user29336
    I am moving into a 4 bedroom two-story unit. It’s roughly 2,200 sq ft. I want absolute max throughput possible to be achieved in all focal points. We’re all in internet related industries. Between gaming and web-development latency and throughput are major factors for us. Here’s our main focal points: 1) Garage (office). downstairs 2) Each bedroom x4. upstairs 3) Living room. downstairs The fastest line we can get is Comcast 50mbdown/5up (Wideband). I am looking for the best way to achieve wireless and wired performance for our setup. Our gaming computers may be in our bedroom, and we also may bring it down to the office every now and then for “LAN” sessions. Most wireless will be happening downstairs with our laptops, but since we may do LAN sessions then hard wired latency may be important there too. My concerns: If we do only wireless there would be too much latency for gaming. I don’t know if placing one D-link DGL 4500 on the top floor would be enough; which I currently own. (http://dlink.com/us/en/home-solutions/support/product/dgl-4500-xtreme-n-gaming-router) As far as I’m aware wireless signals transfer best top down. Would this wireless router be enough on top floor and that’s it? My second strategy was a combination of wiring and wireless but I’m not sure what’s easiest way to do this? This is a place we’re renting, so I’m not sure how much leeway we have with wiring, but we’re all pretty competent... if we can’t drill through a wall we can probably “stitch” them across the edges wherever needed. Thoughts on the optimal way to do this?

  • Looking for an application that scrolls or pans netbook screens running Windows

    - by Rob
    I'm looking for a Windows 7 and XP compatible Windows desktop panning/scrolling tool. This is to solve a problem where some applications for example MSN have settings/preference Windows that are not resizeable. I have a Netbook with a small maximum screen resolution e.g. 1024x600. The fixed non-resizeable windows are too large for this display screen size so I cannot see all of the items on these windows, particularly the OK button to save settings. What I would like is a desktop scrolling/panning tool where if I move my mouse pointer to any edge of the display, it pans to show the region of the too-large-fixed window that I could not see. I use a Samsung N110 and Toshiba NB100 netbooks. I'm looking for: A general program that provides desktop panning/scrolling/expanded resolution to allow all regions of a non-resizeable fixed window Preferably a non-graphics hardware specific program but will accept a solution that works with both the above machines I'm NOT looking for (i.e. unsatisfactory answers others have asked that I've already searched and found): Advice on what programs to use that DON'T have the problem of fixed windows Alternative operating system solutions Plugging in an external monitor with larger resolution - I use this option but I need a solution when one is not available, e.g. while travelling etc Advice about not using small screen netbooks - I enjoy the compact convenience of them Advice about change the dpi settings in the Control Panel Display settings Advice about guesswork with the tab key to move the focus the off-screen item I cannot see Thank you in advance.

  • Immediately tell which output was sent to stderr

    - by Clinton Blackmore
    When automating a task, it is sensible to test it first manually. It would be helpful, though, if any data going to stderr was immediately recognizeable as such, and distinguishable from the data going to stdout, and to have all the output together so it is obvious what the sequence of events is. One last touch that would be nice is if, at program exit, it printed its return code. All of these things would aid in automating. Yes, I can echo the return code when a program finishes, and yes, I can redirect stdout and stderr; what I'd really like it some shell, script, or easy-to-use redirector that shows stdout in black, shows stderr interleaved with it in red, and prints the exit code at the end. Is there such a beast? [If it matters, I'm using Bash 3.2 on Mac OS X]. Update: Sorry it has been months since I've looked at this. I've come up with a simple test script: #!/usr/bin/env python import sys print "this is stdout" print >> sys.stderr, "this is stderr" print "this is stdout again" In my testing (and probably due to the way things are buffered), rse and hilite display everything from stdout and then everything from stderr. The fifo method gets the order right but appears to colourize everything following the stderr line. ind complained about my stdin and stderr lines, and then put the output from stderr last. Most of these solutions are workable, as it is not atypical for only the last output to go to stderr, but still, it'd be nice to have something that worked slightly better.

  • How to run the CPU at something like 75%?

    - by Tobias Kienzler
    My notebook is too old for me to invest into a new fan (it will simply be replaced by a new one when the final heat death occurs), but when it runs on full speed I feel like sitting in front of a vacuum cleaner with integrated cooking... I'm currently using NHC, the Max Battery mode of which let's the CPU run at 50% (~800 MHz). That's fine for most applications, and both temperature and noise remain low. However, on some occasions I need a bit more speed, more around 75% maybe. Can I set the power saving settings somehow so that the CPU won't surpass 75% of it's capability so that an acceptable compromise between power and noise is achieved? I can't set the CPU frequency in the BIOS and since on rare occasions I'd like to be able to switch to 100% without much hassling, hardware solutions like setting jumpers are no option. This answer to a similar (linux!) question mentions NHC should be able to offer these options, but for me they are all greyed out: The notebook is an Asus Z9200K, I guess NHC doesn't support its chipset enough for these advanced options.

  • Why does the screen resolution of 1440x900 suddenly disappear from Intel GMA Control Panel?

    - by GeneQ
    I'm using a Vostro 1200 laptop with the Mobile Intel(R) 965 Express Chipset powering its graphics and running Vista 32-bit SP2. I've been using the Vostro with a Dell SE198WFP LCD Monitor as the external display since day one for about two years without any problems. Recently, I plugged the Vostro into a couple of other monitors. The problem is, now the native resolution for my main monitor's (the SE198WFP) resolution of 1440x900 @ 60 Hz is no longer available. (See below) I've tried everything from uninstalling and reinstalling the Intel drivers as well as the monitor drivers to no avail. I've goggled this problem and it appears that this has happened to other people but all the answers involve people giving up in frustration or reinstalling; both terrible outcomes. Has anybody ever figured why this happens and have a good solution? UPDATE: This dude has a complicated solution, which I haven't tried yet. His explanations for the problem was After an exausting search for an answer to the matter of why my brand new 19? widescreen monitor’s native resolution (1440×900) was unavailible (sic) in the display properties, I finally stumbled upon an article a person posted on Intel’s forums that basically explained what shannanigans Intel had been up to with their GMA 950 line of onboard graphic solutions. Not very comforting.

  • How to deal with the extremely big *.ost files in a Terminal Server environment which is running out of space

    - by Wolfgang Kuehne
    Our Terminal Server is running out of hard disk space, and the major files which occupy most of the space are *.ost files of the Outook, which come form the users which use the Terminal Server all the time through remote desktop. The Outlook is installed on the Terminal Server and various users can use it. What would be a solution in this case. Is there a way to limit the size of the *.ost files? I read in forums that having the Outlook 2010 set up in Cached Exchange Mode isn't the best practice for an environment where the hdd space is a major constraint. First thing that came to my mind is using folder redirection, and place the ost files (together with the AppData forlder) in a network share, but this does not help, because the ost files are saved a part of the AppData folder which can not be redirected. Then I thought if it is possible to limit the size of the ost file? Or limit the time that it keeps emailed cached, say just emails from the last 6 months are sufficient. Another solutions that came to my mind, moving the ost files somewhere else, this required the old ost file to be removed, and creation of a new one. I am not quite sure if the new OST file will still have cached the emails which where available in the old ost, or will it start caching from where the other one left. What do you suggest?

  • Java web app deployment and ControlTier adoption

    - by Ran
    I've been searching for a configuration and deployment manager tool for my java-linux based web service and have been looking mainly at ControlTier (http://controltier.org). We operate at a medium scale (100's of hosts, multi-DC, dozens of services). There seem to be be plenty of lower level system admin tools such as chef, puppet, cfengine, bcfg2 and more and my understanding and the reason I'm calling them "low level" is that they are great for system level administration tasks such as setting up a mount, file permissions, users etc but aren't designed, for example for java deployments, which usually come with a build process and special java semantics. In many cases any tool can be used to do anything but if it was not designed for the task it can get uncomfortable. OTOH control-tier seem to have been designed just for that - java application deployments, at least that's what all the tutorials on their site demonstrate but here's the problem - The wiki at http://controltier.org/wiki/ is pretty good and stuffed with examples and the company behind the open source CT product is very responsive (pushy...) however, I'm yet to have seen any material from 3rd party users on the net. No success stories, no detailed blog posts, no best practices, no cheat sheets, not even hate letters, nothing. This plays badly for DTO solutions, CT's sponsor for two reasons, one is that it makes me suspicious what's the reason for the poor adoption? and second, what do I do if I get stuck and there's no help page on CT's wiki page and the mailing list is too slow to answer. I'm stuck with a "free" product that a consultancy company is pushing. So my question here - I'd be interested in hearing if anyone has had real world experience with CT for java based web app deployments and if he'd thumb up the product? Any other comments that may enlighten me are welcome of course...

  • URL sniffer/downloader

    - by Ricket
    Some websites have Flash content that plays music or videos. Most of the time they don't show you the URL of these music or videos, but for example, you can sniff a YouTube webpage and find the flv file that YouTube is actually requesting and playing. Right now I'm using Orbit Downloader, which has a feature called Grab++ that does just this; you start it, and then you refresh the page, and it shows you all files of certain types (image, audio, video) that the webpage requests, and then you can select one or more and download and it downloads them. But, I don't like Orbit, it installs plugins and has the whole download manager thing which I don't really want. What is a good alternative program? I'm not looking for websites like kickyoutube.com, I want a URL sniffer I guess. HTTPGuideDog used to be my Firefox add-on that did exactly this, but it hasn't been updated even to FF3 (and yes I know I can hack it to load anyway, I'm looking for something natively available preferably). I vaguely know of WireShark but last time I used it, I believe it captures individual packets, which is a little too fine-tuned for me. I just want to be able to see what's happening, and download something that the webpage downloaded. Oh, and I'm using Windows 7. Linux probably has some fancy command-line tool, but it just won't cut it for me. :-\ Edit: Oh, and something free please. Feel free to mention paid solutions though.

  • Email encoding on IIS7

    - by Ivanhoe123
    All emails sent from the server are displaying Cyrillic letters as weird characters, for example: Можно. Regular alphabet letters are properly rendered. I searched all across the web but was not able to find any solutions. Here is some information about the system: Dedicated server with Windows 2008 and IIS7 Application are in PHP (run as FastCGI) If of any importance, Smartermail is installed on the server The emails are sent using PHPs mail() function through a Drupal website. Encoding on that site is set up properly and there are no display issues on front end. Where is the problem? How can I make Cyrillic letters to be properly encoded? Any help is greatly appreciated. Thanks! UPDATE Here are the email headers: Received: from SERVERNAME (mail.domain.com [12.123.123.123]) by mail.domain.com with SMTP; Fri, 16 Nov 2012 00:00:00 +0100 From: [email protected] To: [email protected] Subject: Email subject Date: Fri, 16 Nov 2012 00:00:00 +0100 MIME-Version: 1.0 Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: quoted-printable X-Mailer: Drupal Sender: [email protected] Return-Path: [email protected] Message-ID: f98b801988c642ef911ef46f7cace92b@com X-SmarterMail-Spam: SPF_None, ISpamAssassin 8 [raw: 5], DK_None, DKIM_None, Custom Rules [] X-SmarterMail-TotalSpamWeight: 8

  • Problem with mydomain.com no prefix

    - by user10711
    Short question is. I have a domain name mydomain.com, we have a company website hosted on an IIS server 2003 configuration. Going to the address bar and typing www.mydomain.com will show my website properly. Typing mydomain.com into the same address bar will return an under construction website that seems to be hosted on my webserver. My domain name is hosted by Network Solutions, and I think I have it configured correctly using their advanced DNS services. In their settings I have www.mydomain.com, * and @ also pointed to the ip address of my webserver. On my webserver itself using the IIS manager, under the Web Site, and Web Site Identification. I have configured both www.mydomain.com and mydomain.com configured to work on the IP address on the webserver. I am hosting 4 different websites on my IIS server, all the other sites use prefixes other than www, an example is mail.mydomain.com and a couple of others. None of them show an under construction page as their default homepage. I am really at a loss as to why it would show an under construction page, especially since it seems to be pointing to the correct server. The reason this is such a big deal is because when you search for my company on google, the link there is for mydomain.com and by clicking on the link it shows under construction which is really quite embarrassing. Thanks in advance for any help and if there are further questions let me know.

  • Puppet Decentralized Setup

    - by paul.tw
    I want to migrate my existing Puppet setup from master/client to a decentralized solution. I know other solutions, such as Ansible are easier to setup for that purpose, but I really want to stay with Puppet. I found "supply_drop"(https://github.com/pitluga/supply_drop) on github, so I followed the instructions and did the following: rvm gemset create testing rvm use 1.9.3@testing gem install supply_drop The output is the following: [m@ms-MacBook-Pro:~ $ irb 1.9.3-p547 :001 require 'supply_drop' NameError: uninitialized constant Capistrano from /Users/m/.rvm/gems/ruby-1.9.3-p547@testing/gems/supply_drop-0.17.0/lib/supply_drop/tasks.rb:1:in `' from /Users/m/.rvm/rubies/ruby-1.9.3-p547/lib/ruby/site_ruby/1.9.1/rubygems/core_ext/kernel_require.rb:55:in `require' from /Users/m/.rvm/rubies/ruby-1.9.3-p547/lib/ruby/site_ruby/1.9.1/rubygems/core_ext/kernel_require.rb:55:in `require' from /Users/m/.rvm/gems/ruby-1.9.3-p547@testing/gems/supply_drop-0.17.0/lib/supply_drop.rb:10:in `' from /Users/m/.rvm/rubies/ruby-1.9.3-p547/lib/ruby/site_ruby/1.9.1/rubygems/core_ext/kernel_require.rb:135:in `require' from /Users/m/.rvm/rubies/ruby-1.9.3-p547/lib/ruby/site_ruby/1.9.1/rubygems/core_ext/kernel_require.rb:135:in `rescue in require' from /Users/m/.rvm/rubies/ruby-1.9.3-p547/lib/ruby/site_ruby/1.9.1/rubygems/core_ext/kernel_require.rb:144:in `require' from (irb):1 from /Users/m/.rvm/rubies/ruby-1.9.3-p547/bin/irb:12:in `' Since that doesn't work without problems, I was wondering which alternatives are there available to do the same. Do you have any suggestings?

  • Merge changes in Microsoft Word documents

    - by Álvaro G. Vicario
    I'm using Microsoft Word 2002 to maintain some documentation. The documents are stored in a version control repository (Subversion) together with the source code it documents. My Subversion client (TortoiseSVN) comes with a little VBA script that allows to leverage the built-in revisions feature when merging different branches. In other words, when I want to copy changes from one document to another, Word compares both documents (source and target) and builds a third document that has the contents of the source doc tagged as revisions, so I can then review differences one by one and confirm or discard changes. While this is handy, it also means that making a single change to the source document forces me to review all the differences between both documents and discard all of them except the only actual change. My questions is... Do you know about an application or plug-in that's able to find the differences between two Word documents and apply those differences to a third document? (I know 2002 is very old but that's what my company gives me; I'm open to solutions that use newer versions though.)

  • Forwarding HTTP Request with Direct Server Return

    - by Daniel Crabtree
    I have servers spread across several data centers, each storing different files. I want users to be able to access the files on all servers through a single domain and have the individual servers return the files directly to the users. The following shows a simple example: 1) The user's browser requests http://www.example.com/files/file1.zip 2) Request goes to server A, based on the DNS A record for example.com. 3) Server A analyzes the request and works out that /files/file1.zip is stored on server B. 4) Server A forwards the request to server B. 5) Server B returns file1.zip directly to the user without going through server A. Note: steps 4 and 5 must be transparent to the user and cannot involve sending a redirect to the user as that would violate the requirement of a single domain. From my research, what I want to achieve is called "Direct Server Return" and it is a common setup for load balancing. It is also sometimes called a half reverse proxy. For step 4, it sounds like I need to do MAC Address Translation and then pass the request back onto the network and for servers outside the network of server A tunneling will be required. For step 5, I simply need to configure server B, as per the real servers in a load balancing setup. Namely, server B should have server A's IP address on the loopback interface and it should not answer any ARP requests for that IP address. My problem is how to actually achieve step 4? I have found plenty of hardware and software that can do this for simple load balancing at layer 4, but these solutions fall short and cannot handle the kind of custom routing I require. It seems like I will need to roll my own solution. Ideally, I would like to do the routing / forwarding at the web server level, i.e. in PHP or C# / ASP.net. However, I am open to doing it at a lower level such as Apache or IIS, or at an even lower level, i.e. a custom proxy service in front of everything. Thanks.

  • CPU-adaptive compression

    - by liori
    Hello, Let assume I need to send some data from one computer to another, over a pretty fast network... for example standard 100Mbit connection (~10MB/s). My disk drives are standard HDD, so their speed is somewhere between 30MB/s and 100MB/s. So I guess that compressing the data on the fly could help. But... I don't want to be limited by CPU. If I choose an algorithm that is intensive on CPU, the transfer will actually go slower than without compression. This is difficult with compressors like GZIP and BZIP2 because you usually set the compression strength once for the whole transfer, and my data streams are sometimes easy, sometimes hard to compress--this makes the process suboptimal because sometimes I do not use full CPU, and sometimes the bandwidth is underutilized. Is there a compression program that would adapt to current CPU/bandwidth and hit the sweet spot so that the transfer will be optimal? Ideally for Linux, but I am still curious about all solutions. I'd love to see something compatible with GZIP/BZIP2 decompressors, but this is not necessary. So I'd like to optimize total transfer time, not simply amount of bytes to send. Also I don't need real time decompression... real time compression is enough. The destination host can process the data later in its spare time. I know this doesn't change much (compression is usually much more CPU-intensive than decompression), but if there's a solution that could use this fact, all the better. Each time I am transferring different data, and I really want to make these one-time transfers as quick as possible. So I won't benefit from getting multiple transfers faster due to stronger compression. Thanks,

  • How do I disable the firewall on blackberry?

    - by user15660
    I own a Blackberry 9630 tour.(Sprint). The firewall is enabled with a lock sign and grayed out. I'm not able to disable it. Because of this many of my blackberry apps don't work as it gives a message "The application has tried to open a connection that's not allowed by your IT policy". I tried all options and there's nothing to disable. This is a personal blackberry and I don't have an IT policy on it. I did all methods like wiping, formatting/resetting to factory settings acc. to blackberry site by running their reset app from PC etc etc. but nothing works I tried CrackUtil for blackberry and that worked and wiped the blackberry. I restored my bb and started using it just to notice that the firewall is enabled back after a desktop manager connection to PC. I even made sure the policy.bin file on PC is a regular one with no IT policy. How do I get this disabled? I had the same problem on my old blackberry 8330 and crackutil disabled the firewall. but after a few days after a desktop manager update of blackberry OS and other small stuff the firewall got enabled again. Please give me a solutions to disable the firewall on blackberry

  • internet-based sync software that will keep running after Windows Live Sync stops doing PC-to-PC-syncs?

    - by Warren P
    According to the wikipedia page, Microsoft Live Sync will shortly stop offering the PC-to-PC sync service. There are lots of apps to sync two PCs on the same LAN, but I want to sync two PCs that are in different cities, across the internet, traversing two different NATs, and that requires some kind of service running in the internet that both connect into. There is already a few questions about syncing folders and files, but this is not a duplicate because none of them answer this basic question: Microsoft Live Sync works better than RSYNC, or any of the linked SYNC solutions in any of the "not really duplicates" because it works even when the two PCs have NAT and firewalls between them that forbid direct connectivity, because Windows Live Sync has a free always-on internet server that all the client PCs connect into. I'm looking for a FREE (no-fees) Microsoft Live Sync work-alike PC-to-PC sync solution that works between PCs and Macs, at least, as well as between PCs, and works behind NAT and firewalls at least as well as Microsoft's solution. (Note that Microsoft's solution makes only outbound socket calls to a microsoft server, so this solution must necessarily include a server-hub component that is hosted publically on a free site and which does not require that I set up and manage and pay for my own public internet hosting site) Hint: None of the answers in the linked duplicate are equivalent (PureSync,FreeFileSync,BestSync 2010,SyncButler,Comodo BackUp,QuickShadow,Gbridge) in that none of them work for the PC to Mac situation, where firewalls and nats prevent direct connection, or else they require money to be paid. When Microsoft Live Sync / Live Mesh finally kills direct PC-to-PC mode, the limitation will be that you will have to pay for more than 25 GB of cloud service, and you can then only sync PC #1 to PC #2 if you first sync to the cloud, then down to other clients. I can currently sync 100 gb of data from one computer to another, only temporarily "moving the data" through Microsoft's data servers without using up my Skydrive storage quota.

  • Why can't I boot in to Windows Recovery Environment to fix my HDD or salvage my data?

    - by Kevin
    I've been trying to get in to WindowsRE to salvage the files on my Sony Vaio laptop after it failed to load Vista (it finally, consistently displays "Error loading operating system" after months of such intermittent failures, usually rectified via restarts or utilizing Startup Repair or CHKDSK from WindowsRE) . The problem is, after successfully accessing it once after this failure (and many times before over the course of the laptop's life), I can no longer get it to load. During the last successful access (right after the failure), I ran startup repair, which itself failed and notified me that the boot sector was corrupt. I attempted to head in to Sony's proprietary recovery tools menu, which is accessible from WindowsRE when it is loaded from the recovery partition or recovery disk, however it hung. I have since been unable to access the recovery environment after restarting, using any of these methods: Access via the recovery partition (pressing F10 on boot) Access via recovery DVD (created using the same computer when it was healthy) Access via a Windows Vista installation DVD All three methods produce the same results: The computer acknowledges the boot attempt The computer successfully gets passed the "Windows is loading files" screen The computer successfully gets passed the Windows loading screen The computer then stalls at a black screen, while showing HDD activity (via indicator light). After a few minutes, the HDD activity ceases, and after a few more minutes, the over sized cursor that is utilized in WindowsRE appears on the black screen. The actual recovery environment, however, never appears, even after leaving the computer in such a state overnight. What is fustrating is that other bootable utilities, such as SeaTools for DOS and MemTest, boot up and run fine. In running perfectly normally, MemTest was able to produce a plethora of errors utilizing my RAM. I'm inclined to believe the RAM's faultiness may causing the WindowsRE booting to fail. Would this be a valid assumption? If I'm not mistaken, booting from external media utilizes the RAM, so such a reason is plausible, assuming my knowledge of bootloading is correct. Other than that, I can't figure out any reason why all the bootable utilities except WindowsRE run fine. Does anyone know what the problem is, or could be? Any solutions?

  • Fully FOSS EMail solution

    - by Ravi
    I am looking at various FOSS options to build a robust EMail solution for a government funded university. Commercial options are to be chosen only in the worst case scenario. Here are the requirements: Approx 1000-1500 users - Postfix or Exim? (Sendmail is out;-)) Mailing lists for different groups/Need web based archive - Mailman? Sympa? Centralised identity store - OpenLDAP? Fedora 389DS? Secure IMAP only - no POP3 required - Courier? Dovecot? Cyrus?? Anti Spam - SpamAssasin? what else? Calendaring - ?? webmail - good to have, not mandatory - needs to be very secure...so squirrelmail is out;-)? Other questions: What mailbox storage format to use? where to store? database/file system? Simple and effective HA options? Is there a web proxy equivalent to squid in the mail server world? software load balancers?CARP? Monitoring and alert? Backup? The govt wants to stimulate the local economy by buying hardware locally from whitebox vendors. Also local consultants and university students will do the integration. We looked at out-of-the-box integrated solutions like Axigen, Zimbra and GMail but each was ruled out in favour of a DIY approach in the hopes of full control over the data and avoiding vendor lockin - which i though was a smart thing to do. I wish more provincial governments in the developing world think of these sort of initiatives As for OS - Debian, FreeBSD would be first preference. Commercial OS's need not apply. CentOS as second tier option...

  • What are some techniques to monitor multiple instances of a piece of software?

    - by Geo Ego
    It was recommended that I ask this question here by a member of StackOverflow. I have a piece of self-serve kiosk software that will be running at multiple sites. I'd like to monitor their status remotely. The kiosk application itself is pretty much finished. I am now in the process of creating a piece of software that will monitor all of the kiosks from a central location so that the customer can view particular details remotely (for instance, how many bills are in the acceptor's cash cartridge, what customer is currently logged in, etc.). Because I am in such an early stage of development, my options are quite open. I understand that I'm not giving very many qualifications, but I'd like to try to get a good variety of potential solutions. Some details: Kiosk software is a VB6 app running on Windows Embedded Monitoring software will be run on a modern desktop version of Windows (either XP, Vista, or 7) Database is SQL Server 2008 My initial idea was to develop a .NET app that would simply report the last database transaction for each kiosk at a set interval (say every second or so) but I'd really like for the kiosk software to report its status in real-time. I'm not exactly sure where to begin in terms of what modifications may need to be made to the kiosk software, and what the monitoring software will require. Links to articles on these topics would be most welcome.

  • iPhone Lag Terrible - SLOW - What's going on with the iPhone OS?

    - by Sam Schutte
    I've had my iPhone 3G for about a year now, and it seems like at least once a month, it gets bogged down and gets slower and slower - horrible lag when typing, going back to the home screen or opening an app can take 20 seconds. Has anyone else run into this and found "the" solution. What you always read on other boards is to reboot the handset (hold down home and the power button), but that doesn't improve anything for me. I've reinstalled the OS like 5 times now, and I'm getting pretty sick of doing it so often. And I don't buy that it's a hardware issue really, since it works fine for weeks after a fresh install. Anyone have a solution or an idea of what specific actions cause this kind of evident data corruption (OS corruption?) and slowness? Note - I'm looking for specific things here. That is, has anyone done the research to see exactly what on the phone operating system is getting messed up that causes this lag (which is discussed all over the internet, with no working solutions). I don't own a mac, so I can't delve into the guts of the iPhone very well to see what's up with it... Some additional info: Reboots (hold down power/home) and "Sleeps" (slide off) do nothing. Only fresh re-installs help I only have about 15 apps installed - sometimes you see the answer to uninstall apps if you have too many, I'd hope that 15 isn't too many, and even when I've had none installed, it still gets hung up after a period of time. This phone is not jailbroken, and it is running the 3.0.1 release.

  • Windows 7 taskbar groups to use vertical menus only, not thumbnails?

    - by Justin Grant
    I frequently have 10 or more windows of the same application (e.g. Outlook, Word, IE, etc.) open at one time. Windows 7's new taskbar grouping thumbnail feature shows a preview of open windows (aka thumbnails) when you single-click on the taskbar group for that application. But when I have over 10 windows open (more thumbnails than will fit horizontally on my screen), Windows reverts to a vertical menu. This is disconcerting since I need to train myself to deal with two separate behaviors and can never anticipate what I'm going to see when I click on a taskbar group. Furthermore, I find the thumbnails more difficult to visually scan through (vs. the vertical menu) because only 1-2 words of each window's title are shown. Typically that's not enough text to disambiguate and help me find the right window. I'd like to force Windows 7's taskbar grouping to always show a vertical menu (like in XP) instead of sometimes showing thumbnail previews and sometimes showing a vertical menu. Anyone know how (whether?) this can be done? UPDATE: BTW, I'm running the RTM version (build 7600) of Windows 7. There are apparently other solutions out there which work on earlier builds, but which don't work on the RTM build.
