• HDMI-HDMI cable length

  - by alex

  I'd like to connect my PC to an HDTV using an HDMI-HDMI cable. The distance between them is about 8 m; is the length going to be an issue? I'm worried the signal might deteriorate over such a distance. Also, does price have any major impact on the signal quality? I'd like to buy an 8-10 m cable for somewhere around 20$. Would such a cheap cable be good for what I want?

• How to connect two monitors to a macbook pro?

  - by CIRK

  I have a 13" macbook pro, and I need much more space right now, so I decided to buy two smaller monitors. (these from LG). But I don't really know how will I connect them. I've seen some products like this Diamond BVU195, but it's not currently in stores in my country. I've found these Equip 128450 USB 2.0 Display Adapter DELOCK USB 2.0 to DVI/VGA/HDMI Adapter The second one looks pretty cool, but it says that Windows is a system requirement or what, so I'm not sure if it will work with mac os x? So how did you connected multiple monitors to you mac, and are these adapters the best choices, if yes then is there an OS independent one?

• Antivirus Configuration for dedicated SQL and dedicated IIS Servers

  - by Wayne Arthurton

  Our corporate standard is McAfee Enterprise, unfortunately this is non-negotiable. On two types of servers I'm responsible for, SQL & Web, we have noticed major performance issues with the corporate standard setup. Max scan time 45sec One policy for all processes Scan ALL files on write, read and open for backup Heuristics: Find unknown programs, trojans and macros Detect unwanted programs Exclude: EVT, LDF, LOG, MDF, VMD, , windows file protection) This of course still causes major slowdowns. IIS .NET recompiles are slow especially with SharePoint, SQL backups and restores, SQL Analysis Services, Integration Services and temp data from them as well. I have looked from time to time, for some best practices on setting up McAfee of SQL & SQL Analysis Service, SQL Integration Service, Visual Studio, Sharepoint, and .NET web servers in general. How do people setup McAfee enterprise on their corporate serves keeping security intact, but affecting performance as minimally as possible? Has anyone run across white papers on these setups? Obviously some are case by case, but there must be some best practices out there somewhere.

• Supplementary Developer Laptop

  - by David Smith

  I'm looking to buy a laptop with the following specs for a developer. The goal will be to have a development machine supplementing the devs desktop. During work hours the dev will be on a beefy desktop. For working while on the go: trains, client sites, code camps, it would be nice to have a machine which can run Visual Studio 2008 without needing to remote desktop into their primary machine. What do you think is the lowest cost laptop meeting this need? Here are the specs I have in mind: SSD drive 64GB-doesn't need to be huge, most data is stored on servers. Will need to fit Windows 7, IIS, SQL Server, and Visual Studio 2010. RAM-3GB processor =Pentium Core 2 duo Screen size = 14 inches. OS doesn't matter. It will be paved with Windows 7 Ultimate optical drive omitted would be a plus. weight and battery life aren't so important because the machine will be plugged in almost all the time.

• Dual monitors through 1 HDMI port

  - by Carlos

  I currently have a Dell Studio XPS 13 laptop connected to a 24" HP monitor (w2448hc). Im thinking on getting a second one, however am wondering what i need for the setup (hardware wise). Also I was wondering it there is any down side to it, or something i should be aware of. For example, image quality loss, GPU overloading, or anything important I should know. More than anything Im interested in your advice. Also the monitors do have built in speakers (HDMI sound output), is the sound going to be reproduced by only one monitor or both? Specs Model: Dell Studio XPS 13 OS: Genuine Windows® 7 Home Premium 64-Bit CPU: Intel® CoreTM 2 Duo P8600 (2.4GHz, 3MB L2 Cache, 1067MHz FSB) Chipset: NVIDIA® GeForce® MCP79MX RAM: 4GB 1067MHz DDR3 SDRAM Graphics: SLi NVIDIA® GeForce® 9500M - 256MB Thanks for your advice, if there is anything additional i need to buy an you have a personal preference pass the brand name so i can check it out.

• Videoediting slow on windows with HD footage in .MOV format

  - by Joakim

  My camera is a Canon 5D mark II that serves me .mov files in HD. But these are a pain in the neck to edit on my pc. I have tried Premier, Vegas, Pinnacle, etc, but it is almost impossible to edit and do a movie. I do have a good computer with Windows7 but that doesn't help me, and I don't want to buy a new monster pc just for that task. Question: I could convert the files, but what would be the best format? I don't want to lose much quality. Anyone have any ideas?

• replace laptop hard disk

  - by 5YrsLaterDBA

  I have bought a ACER Aspire 5736Z-4790 laptop for my parents. It just passed the warranty. I think the hard disk is bad now. I cannot open/copy some of my files. It will crash (blue screen) when I do chkdsk /f/r in the stage 4 of 5 which is verifying file data. I can hear a strange noise when it is reading the bad sectors (I guess because it hangs there.) I am thinking replace the hard disk. should I buy the same hard disk or any SATA laptop hard disk will be ok? BTW, is there a way to repair it (with software)?

• Replacement mouse "feet"?

  - by Jeff Atwood

  The plastic skid pad "feet" on the bottom of my Logitech G9 mouse (which I love!) are getting rather worn down -- to the point that the outer shell of the mouse scrapes on the mousepad a bit. I've had the mouse for about ~2 years now so it does get a lot (I mean lot of use). But, I hate to buy a new mouse when I only need replacement "feet". Where can I obtain replacement mouse feet? Is this even possible?

• Rosetta Stone Network V3 doesn't recognize built-in microphone in OSX Lion

  - by zarose

  I am using Rosetta Stone Network V3 on an early 2011 MacBook Pro running OSX Lion 10.7.3. When I log in, select a language and level, and then a lesson, I am prompted to select a microphone. The built in microphone doesn't show up, yet I've used it multiple times for other applications. I heard from another user that it doesn't work if headphones with a built-in microphone are used. I have not yet tried a USB microphone. Is there some free work around to this? I would prefer to not have to buy a USB microphone, but if that is the only solution, then I'll live. Edit: I noticed that Rosetta Stone tells me that if I don't have a microphone I should disable speech to move on, but that option is grayed out for me.

• Suggestions for a nice&small - high battery life programmer notebook

  - by Emir

  Hi guys, I'm planning to buy a new notebook since the Toshiba I have now sucks in battery life. I'm a web designer & programmer, and the main features of the notebook should be: High battery life Small, 13.3" or 14" screen A fast processor and RAM that won't let me down while multi-tasking Anything other than these is secondary, I wouldn't like it to be very pricey though :) I'm now leaning towards Macbook Pro 13.3", 2.66 Ghz; it has 10 hours of battery life. However, I mostly develop on Windows, so I don't know how many hours of battery will I get if I run Windows 7 on Bootcamp. Your ideas and suggestions will be much appreciated.

• Is there a way to make Apple Mail work well with Exchange server calendar?

  - by Joshua Frank

  My office uses Macs, but most of our clients use Windows and Outlook. Whenever people send invitations from Apple Mail to a Windows/Outlook machine, the invitations are garbled and look nothing like the nicely formatted invitations that Outlook people are used to. We also have no tools to view shared calendars, so we can choose mutually open time slots, and other useful calendar features that Outlook has and Apple Mail seems not to. So is there a plugin or third party program that will give Apple Mail the nice calendar features of Outlook? (By the way, I've looked into actually buying Outlook for Mac, and the pricing is kind of prohibitive, because you MUST buy the whole Office Suite, which we already have, there's no upgrade path, and there's no volume discounting.)

• STORM Cloud Servers — Anybody Used Them? Any Reviews and/or Advice? [closed]

  - by AJB

  I just posted this in StackOverflow before I realized that Serverfault existed ... Hi folks, Just wondering if anyone has used STORM Cloud Servers from Liquid Web: https://www.stormondemand.com/cloud-server/ I'm shopping for a new hosting provider for my server that has about 50 'mom & pop' domains on it and finding that webhosting has changed a lot in the last ten years. I feel like I'm trying to buy 100 cellphone plans at once. Any advice would be greatly appreciated. Thanks.

• Virtual Machines Renaming/Backing up/Sharing

  - by evan

  I've started using VMware virtual machines for all of my software development projects and have a few questions for others doing the same thing. First, how can you rename the virtual machine and the name of the virtual hard drive? I have a base development machine that I clone for different projects. I'd like to name the machine and it's hard drive according the the project (right now when I copy them via cut and paste, the file names remain the same and I can only organize them by putting them in a specific directory). Second, what is the best way to back up a virtual machine? Is it possible (by breaking the virtual hard drive up into chunks instead of one big file) to get incremental backups working? It seems time machine always tries to make a copy of the whole thing which is time consuming because each virtual machine is around 30GB. Finally, how slow would it be to have a virtual machine shared on an NFS mount on a wireless N network and used from multiple computers (but with only one person using it at a time.) Would it be more reasonable on a gigabit lan connection? Thanks for your input! And please feel free to share any advice or wisdom about using virtual machines for software development and the best ways to speed them up!

• Can a usb cable carry 12v?

  - by zm15

  Here's what i'm wanting to do. I have a Acer Iconia A500 tablet. I want to plug it in, in the car, but it has a barrel plug and I don't want to buy an inverter. The car adapters are expensive for what they do. I already have a 2.1 amp usb car charger meant for the iPad: http://www.amazon.com/Kensington-K33497US-PowerBolt-Charger-Compatible/dp/tech-data/B003PU01M4/ref=de_a_smtd And i want to use this usb cable from the 2.1 amp port to plug into the A500: http://www.amazon.com/gp/product/B00304DZ7I/ref=ox_sc_act_title_2?ie=UTF8&m=A1HPBDJJIXKXS7 Here are the specs on the original wall charger if that helps: http://www.phihong.com/assets/pdf/PSA18R.pdf The usb cable says it's 5v, but the original charger says it outputs 12v. But since it's just a cable... wasn't sure if that really made a whole lot of difference since it's only 1.5 amps from the wall charger. Is it possible to use that usb cable through the powerbolt car charger, to charge the A500?

• Apache Caching and Expires configuration

  - by mcondiff

  I'm looking for a best possible caching/expires configuration for my specific situation. I realize that some sites have advocated turning etags off: Header unset ETag, FileETag None I know that I should use either Expires or Cache-Control. In additions, I know that I should use either Last-modified or ETAGs (Per ySlow docs). I inherited a clients server that uses the following in .htaccess: <FilesMatch "\.(ico|pdf|flv|jpg|jpeg|png|gif|js|css|swf|xml|txt|html|htm)$"> Header set Cache-Control "max-age=172800, public, must-revalidate" </FilesMatch> With this server I am not going to be able to rely on staff to rename images, css and js in web applications so I do not want to set the expires far in the future without knowing (with a good certainty) that "most/all" browsers will check to see if content has changed. What I do not want to happen is someone call me and say the website is broken because they replaced an image and it's not showing up. But I do want to take the most advantage I can with caching and expires while still maintaining that mostly all browsers will check with the server to see if components have changed. I have access to both the .htaccess and apache .conf file and it is a single server, the content is not deployed on multiple servers. What would be the best .htaccess or .conf configuration for me to achieve my goals for this clients server? Thanks for your help

• Inverted function keys (F1-F12) on HP Pavilion dv4t

  - by The Electric Muffin

  (I know there have already been a lot of questions about this, but none of them mentioned the dv4t specifically.) I'm thinking about getting an HP Pavilion dv4t-4200 or -5100, but something that's really irritating me is that by default the function keys (F1-F12) are "inverted"—without holding the Fn key, the function keys do things like change the brightness, change or mute the volume, and switch to an external display. Only if you hold Fn will they actually produce F1, F2, etc. This is not how keyboards are supposed to work. Is there any way to disable this "feature" that has been verified to work on the HP Pavilion dv4t-4200 or HP Pavilion dv4t-5100? I don't want to buy this computer unless this is possible.

• Self-powered USB hub and power supply adapter ampere capacity

  - by galacticninja

  I am looking for a power supply adapter for my USB Hub so it can support at least 2 bus-powered external hard drives. The hub's rating is 5 volts, 2 amperes. I would like to know if it would be OK to buy a power supply adapter rated at less than 2A. I've been looking for power supply adapters and the ones that do support 2A are more expensive (more expensive than the USB hub itself) compared to those that support less than 2A. Will power supply adapter that supports less than 2A (~1-1.5A) work fine to support two external hard drives? The external hard drives are both bus-powered Western Digital My Passport Essentials 250 GB. The OS is Windows XP SP3.

• Is it possible to be a Linux professional studying on your own?

  - by Marc Jr

  I read economics at university(nothing to see with linux, isn't it? :P). I have some basic knowledge about booting process, Linux Kernel compiling from source and stuff like that. But of course I have still much to learn sometimes some errors appears and "voila" I am lost. I had: Ubuntu, Fedora, OpenSuse, Arch.. using Gentoo now. I'd like to know what you linux users, professionals, administrators... would think it is the best way to learn linux in a professional way. Is it worth studying it and passing the LPIC test enough to work in the linux world? or do I need going to IT uni? I've heard LFS is a good way of learning about linux, is that real? I've been thinking about getting to LFS learn about more deeply about the linux process and learning scripts. It is possible to do this way? if anyone has a tip or a good way of doing, maybe someone did it. Any tip is very welcome. Words from a person in love with linux. :D The best, Marc

• Windows Home Server style redundancy/multi-disk-support on Windows Server 2008 R2?

  - by user19597

  I'm setting up a fileserver for our department. It'll be connected to the domain. I want it to have a very large amount of storage (several TB). Ideally, it should also preserve disk space by identifying identical files and only storing them once. It should be fault tollerant so that if one of the drives fails, that drive can be replaced without losing any data. All of these features are available in Microsoft's consumer offering - Windows Home Server. However, I can't find these kind of features within the enterprise Windows Server 2008 R2. Am I missing something? I know that I could buy a Drobo, or similar, and use this instead. However, I would prefer to use a built-in feature of Windows Server should it exist. It seems surprising to me that these features should be available in Home Server but not in an enterprise fileserver.

• Can my laptop run dual 1080p (Sony Vaio - Nvidia 330M)

  - by Charlino

  I am looking to buy a monitor to setup dual monitors for my laptop and was wondering if my laptop could handle 2 x 1080p. I have a Sony Vaio VPCF116FG which has a Nvidia GeForce 330M chip and 1GB dedicated graphics memory. The laptop also has a Intel® Core™ i7-720QM Processor (1.60 GHz with Turbo Boost up to 2.80 GHz) but I don't know if that's relevant(?). The laptop screen has a native resolution of 1080p (1920 x 1080) so I'll be looking at buying a external monitor with 1080p to connect up using a HDMI cable. So, the question is, will my laptop be able to handle it's own 1080p screen AND an external 1080p screen? TIA, Charles
