• Why do msi installations use slower drives over faster ones in windows 7?

  - by Joshua C

  I have noticed that the slowest drive in my system is used most during an msi installation. I mainly notice this when running windows updates but it seems to be msi installs in general. The setup I last saw this occur on was running Windows 7 with the following drives: Sata: 240GB SSD NTFS ~515MB/s Operating system drive 1TB NTFS ~110MB/s Firewire: 4TB ExFAT ~80MB/s I would think that windows would choose the fastest drive with available space for temporary files. But it will instead choose the external drive with the slowest transfer speed. I could also understand choosing the 1TB for not being an ssd in an attempt to preserve the longevity of the ssd write capacity. Why does this happen? Is there a way to force these installations to use the OS drive or a specific drive?

• KB2494088 Always Fails : How to get it to install (or stop trying to)?

  - by Peter K.

  I have a problem where KB2494088 (a SQL Server 2008 R2 patch) continually fails to install when I reboot my system. Downloading the manual patch and trying to apply it says: The SQL Server patch package is part of a general distribution release (GDR). This package cannot be applied since this SQL Server feature has already been patched. To continue, you must install a higher version of the SQL Server patch. Most other posts (this, this) suggest it's either a failed (or cancelled) past installation or requires a SQL server repair. I've looked at registry settings and tried the repair option, but nothing seems to work.

• I'm an emacs user. How do I learn vim?

  - by Jason Baker

  Most of the time, I use emacs. However, I've decided to try to learn vim. I'm happy with emacs, I just am trying to avoid having it turn into Maslow's Hammer. I've seen a few tutorials, but I have yet to see a good one written from the standpoint of someone coming from emacs. Is there any general advice that someone who's undergone this learning process before can give me? Most importantly, what are some concepts in Vim that may not be intuitive to me coming from an emacs background?

• how do applications (and OS) handle very big files?

  - by DrStrangeLove

  For instance, i have video file which is 11.8 Gb, but my RAM memory only 2 Gb.. How does VLC (or other software) handle it? How do they load it into memory? I used VMMap tool (from sysinternals) to take a look at memory, and i saw: private 160000K working set 100000K Obviously, it's much less than 11.8 Gb -So how did it happen? This question is not only about video. I'd like to know how computer, in general, handles very large files.

• VMware Workstation 9 Security Best Practice Guides

  - by slickboy

  Could someone please point me in the direction of where I could find some best practice securiy guides for VMware Workstation 9 please? I've searched the VMware site and to say it's badly organised is an understatement! I've been able to find general setup guides but nothing with a specific focus on security. I'm also wondering is there any best practice guides that I should follow when installing Windows 7 Professional and Windows Server 2008 R2 on VMware Workstation 9? I obviously will be implementing Microsofts recommended security best practices but I'd be very interested in any recommendations for virtualizing these operating systems. Any help is much appreciated.

• Unable to Get IIS Response Times with Hyperic Monitoring Tool

  - by jwmajors81

  We have a very large .NET application (vendor) that I am trying to gather performance metrics for using Hyperic. In general I wanted to be able to report response times for each of the components within the application, which include: Web Services ASP.NET Pages MSMQ I am currently unable to successfully monitor the response times for IIS on my windows machines. I have successfully auto-discovered them and I am getting diagnostic information, but am not getting back the response times. After looking online at what other people are seeing, I found that I am missing a tab for the response times which is usually next to the metrics tab. Also, when I look at the configuration screen for IIS I do not see a field which enables me to specify where the log files are located at. Please note that my logs are located at e:\LogFiles\ instead of the usual location because our IT staff doesn't allocate much space for the C: drive. Please note that I have the MSMQ monitors up and running great. Any assistance would be greatly appreciated. Thanks, Jeremy

• Asus V1S/V1V inverter cable

  - by Bill

  I have an Asus V1V, which is the same as the Asus V1S except for the video card. I have a problem where the screen will randomly lose brightness or flicker between being lit and not lit. The picture below is of the left hinge, with the cover removed. Pressing one of these cables affects this behaviour, and pressing it in place will resolve the issue for a few hours. To me this means the inverter cable is damaged. As the picture shows, there are two cables, an LCD cable and what I assume is an inverter cable. I purchased an LCD cable for my model of laptop, but have been unable to find an inverter cable. It seems not to exist. I would like some input on if an inverter cable actually exists, if it is likely the problem, or solutions in general to resolve this problem permanently.

• A minimal Linux distribution for my ASUS EEE PC

  - by Andrioid

  I recently bought myself a ASUS EEE 1000HE and I intend to use it for note-taking and light browsing at the University. The machine has a 10" screen so the interface needs to be very compact. I've already tried: EEEbuntu: Very nice driver support and out of the box experience. But I feel that it is too slow booting and the general experience is too heavy in my opinion. Moblin 2: Looks very cool, boots just fine but is way too unstable to use. Also find it annoying that I can't find hotkey documentation anywhere. Any Netbook OS recommendation welcome (although those specific to my model would be great). There is an entire jungle of distributions out there, so if you've been on a safari, please share your experience.

• Which e-reader for O'Reilly books?

  - by Tim

  Most of my programming books are from O'Reilly. Several of them need to be updated, and I'm thinking of going for an e-reader this time. O'Reilly sell their e-books as a multi-format bundle (PDF, EPUB and Mobipocket (Kindle)). Has anyone done a comparison of the formats as for suitability on a small e-reader screen? In Europe, the Kindle DX is not (yet?) available, so I'm not sure whether a Kindle or a Sony (or some other reader) is best suited for these books. Disregarding other advantages/disadvantages of the different readers for now, which one in your opinion gives the best experience with O'Reilly books in particular (or programming books in general)?

• acessing a subnetwork from within a vm

  - by yan bellavance

  I have a pc running windows 7. I have vmwareplayer running RHEL5 I have 1 physical ethernet connection. this ethernet connection is wired to a hub. there is another device on that hub that needs to be in a certain subnetwork (192.168.0.xxx)(lets call him device X) but the general network is 192.168.1.xxx How can I configure the network adapters so that I can ping device X from RHEL5 in the vm. Originally I could ping google from both windows and rhel (I was in the .1 network) but not device X since he is on a different subnetwork address. Now that I have put it on the .0 I can ping device X from windows but not from rhel5 and cannot access the web. I did this by manually setting the IP address.

• Unable to connect to sites using IIS7 Manager

  - by Phil.Wheeler

  I'm a developer who has been assigned the task of managing and configuring a new IIS7 instance on a remote server. My domain account has been added as to the local Administrators group on the box, but IIS7 has been configured to accept connections only from accounts with Windows credentials. I've added my domain account to the IIS Manager Permissions for one of my sites, but I'm still unable to connect to either that site, the IIS instance or the server in general from my local machine. There's obviously a missing element to the configuration of this setup but I don't know where to start looking. The event logs on the IIS box show audit failures for my account when trying to connect remote via the IIS7 Manager tool on my local machine. Suggestions gratefully received.

• Server 2008 Hard Faults

  - by claw

  Hey all, plase bear with me as I haven't looked at a server in a very long time. The problem I am having is with a Windows 2008 Standard FE Service Pack 2 Intel Xeon X3430 @ 2.40 2.39 GHZ 4 GB Memory 64 Bit There seems to be no problems other than the physical memory peaking at 91%, always with over 100 Hard Faults Per Second. To my understanding hard faults should be fairly rare on a machine with. Are there any logs I can show you? Or investigate myself. The general performance of the machine is ok, i can access SBS2008 and change settings fairly smoothly without hangs etc. However, we connect to the server and do quite a bit of SQL via an application. For a record to retrieve say 20 rows, it can take 20+ seconds. Thanks in advance, Jamie EDIT: What the server is used for: IIS ASP Web Service SQL 2008 List item Exchange unable to upload screenshots due to low reputation - why doesnt my SO work here :)

• Worth it to move /var to physical disk vs logical?

  - by Tammer Ibrahim

  Brief question about partition layout. I use an SSD for /, /boot, /usr, & /home partitions. I'd like to move /var to a mechanical disk to minimize writes to the SSD. I'm mainly concerned about maximizing drive life rather than maximizing performance (although I obviously wouldn't want to cripple my server). My mechanical disks consist of two drives sharing LVM, and a third used for nightly rsync backups. I also have a bunch of old 2.5in hard disks lying around. My question is, should I simply create a new LVM volume '/var' on my primary data store, or would it be worth the increased energy consumption (in terms of maximizing the lifetime of the LVMed drives) to install a low volume 2.5in disk to use just for /var? On a more general level my question is about the trade offs of placing OS mounts on the same physical volumes as my data. Thanks for any help!

• Thinking about buying a LG 30" monitor

  - by evan

  I'd love to get http://www.newegg.com/Product/Product.aspx?Item=N82E16824005115 but I'm wondering if I should hold out until more LED monitors are on the market. I love really like the brightness of the 27" imac monitor and the above monitor is only rated at 5 cd/m2 less than that monitor, but wouldn't a back lit monitor appear to be much brighter than an LCD monitor? Does anyone know how the above monitor compares to the 27" imac monitor? Why are Apple monitors in general so much more expensive than other monitors - just the brand name? I must be confused about how to read the specs? Thanks in advance for your input!

• baffling stat pauses - (reiserfs)

  - by Twirrim

  I've got a SuSE server with reiserfs formatted partitions, all on a RAID1 mirror. I'm noticing odd spikes in iowait, but generally all seems okay. iostat claims not even 3% iowait in general: avg-cpu: %user %nice %system %iowait %steal %idle 6.53 0.03 1.45 2.92 0.00 89.07 After tracking down some odd behaviour when ls'ing, it appears "stat" (ls is aliased to include color which does a stat process on each file) randomly takes 5 seconds on a file in the directory. ReiserFS does a file system sync every 5 seconds, but that's interval between not length of time taken to sync. Out of curiosity I did remount using noatime to see if that would help though as it would reduce sync's workload, but no joy. Anyone got any thoughts what might be causing this pause? Disks appear healthy, RAID controller believes the RAID is healthy, and io stats show the disks aren't working very hard at all.

• Troubleshooting a high SQL Server Compilation/Batch-Ratio

  - by Sleepless

  I have a SQL Server (quad core x86, 4GB RAM) that constantly has almost the same values for "SQLServer:SQL Statistics: SQL compilations/sec" and "SQLServer:SQL Statistics: SQL batches/sec". This could be interpreted as a server running 100% ad hoc queries, each one of which has to be recompiled, but this is not the case here. The sys.dm_exec_query_stats DMV lists hundreds of query plans with an execution_count much larger than 1. Does anybody have any idea how to interpret / troubleshoot this phenomenon? BTW, the server's general performance counters (CPU,I/O,RAM) all show very modest utilization.

• hardware for pushing buttons

  - by Elazar Leibovich

  Many times I want my computer to interface old hardware. Such as radio, light switch, etc. This mostly involves pushing pressing and moving various buttons and switches. I don't want to buy new hardware I want my computer to interface the old hardware I already have. I thought about it and reached to the conclusion that what I need is a general purpose button-pusher hardware. I need a simple device I can interface by a computer and would be able to push most of the buttons we have in daily accessories, without damaging the button. Is there any such accessory availible?

• video streaming infrastructure advice

  - by Alchemical

  We would like to set-up a live video-chat web site and are looking for basic recomendations for software and hardware set-up. Most streams will be broadcast live from a single person with a web cam, etc., and viewed by typically 1-10 people, although there could be up to 100+ viewers on the high side. Audio and video do not have to be super-high quality, but do need to be "good enough". The main point is to convey the basic info in the video (and audio). If occasionally the frame-rate drops low and then goes back to normal fairly soon, we could live with that. Budget is an issue, so we are in general looking for a lower cost solution that will give us most of what we need in temers of performance and quality. We are looking at Peer1 for co-lo. The rest of our web site will be .Net / Windows platform. We are open to looking at any platform for the best streaming solution, although our technical expertise is currently more on the Windows side.

• Best practices for re-IP'ing / migrating servers and applications

  - by warren

  Some of this question would be highly application-specific, but what approaches do you take when looking to migrate applications from one server/platform to another and servers form one network segment to another? For applications that can't be re-IP'd (many exist in this category), the general answer is to nuke and pave (or extend a clusterable application, then remove the segment that needs to be "moved"). For "normal" applications (httpd, mail, directory services, etc), what are the checks ou perform before, during, and after a move to ensure the health of the migrated app/server? An example with Apache: backup httpd conf directory change httpd conf files to use new IP address of server change (or add) IP of server restart Apache verify web server still serves pages reboot server verify environment comes back up healthy

• IT Audit checklist

  - by PHLiGHT

  I recently have taken on the position of a one man show for a company that is going to have an audit. The network isn't anywhere close to prepared and I have been looking for a general audit checklist since one hasn't been provided by the auditors and haven't found much good information out there. Does anyone have a nice template that will give me a good starting point. I know that this will be highly customized to the company but a starting point will be helpful to outline to management just how much work is needed. Thanks,

• Macro to manage sport ranking and calendar?

  - by Ale

  I need to write a macro to manage ranking and calendar for curling turnament. The event will follow the Shenkel system first match determined by general draw after that every team has played one match is possible to determine the first ranking second match determined by the rule: 1st vs. 2nd - 3rd vs. 4th - 5th vs. 6th and so on after that every team has played two matches is possible to determine the second ranking and so on until the end (3 to 5 matches normally). Another rule is that from the second match is not possible to play against a team that I played before! I was thinking to use MS-excel but also Calc (both LibreOffice/OpenOffice) should be fine. Thanks in advanced

• HTTP 401 Challenge and HTTP 302 Login/Redirect won't work together in IIS7

  - by RandomBen

  I am developing a website using .NET 3.5 that allow users to visit the site and create logins using the standard Microsoft login controls. However, users do not need to login to do general things like view products. Now I need to setup the site so some of our Traveling Sales people are able to access it but not allow anyone else to access it. The easiest way I know how to do this is to turn on Windows Authentication for the Site in IIS7. When I do that I get all sorts of errors due to also having Forms Authentication turned on. If I turn Forms Auth then I get a different kind of error. Does anyone know how to make Forms Auth and Windows Auth play nice on a single site in IIS7 or some other way to create a required login without having me kill Forms Auth?
