• Mini-ITX board for AM3 Athlon X4 600e processor.

  - by Kamil Zadora

  Hello, I am planning to build a PC to control a robotic platform that I am building (about 50% complete). I need more power than ATOM platform could bring, as the robot will need to do on the fly image processing to work as intended. I was considering using Athlon X4 600e as it is rated 45W Maximum output. Probably underclocked it would go lower than 30-35W. I do not I'am at very long battery life, but the 17Ah, 12V battery should keep it running for few hours. My problem is: motherboard. I am space limited so I am looking for a nice mini-itx AM3 motherboard to match the processor. It is hard to find many tests about power usage of the motherboards itself (for example, when using the same processor on different motherboards, test are usualy done in the opposite matter). Could you provide any motherboard examples or suggest what chipset to look for? Thank you in advance.

• Pitfalls to using Gluster as a home/profile directory server?

  - by Bart Silverstrim

  I was asking recently about options for divvying up access to file servers, as we have a NAS solution that gets fairly bogged down when our users (with giant profiles, especially) all log in nearly simultaneously. I ran across Gluster and it looks like it can cluster different physical storage media into a single virtual volume and share it out like a virtual NAS from the client perspective and it support CIFS. My question is whether something like this would be feasible to use for home and profile directories in an active directory environment. I was worried about ACL's, primarily, as I didn't think CIFS was fine-grained enough to support NTFS permissions and it didn't look like Gluster exports those permission levels, just the base permissions for basic file sharing. I got the impression that using Gluster would allow for data to be redundant across multiple servers and would speed up access to the files under heavy load, while allowing us to dynamically boost storage capacity by just adding another server and telling Gluster's master node to add that server. Maybe I'm wrong with my understanding of it though. Anyone else use it or care to share how feasible this is?

• Can I ? - Develop C/C++ in Fedora 14 using GCC 4.4 and deploy in CentOS 5.2 using GCC 4.4

  - by Amit Phatarphekar

  Hello - My production env runs CentOS 5.2 and 5.5 versions. I have to develop a new tool using C/C++ and deploy it on this production env. I was planning to use Fedora 14 on my desktop with GCC 4.4 to do the development with Eclipse IDE. And then later I want to deploy the executables to CentOS 5.2 or 5.5 The production env will have GCC 4.4 as well. Since both Fedora and CentOS are RHEL based, I thought this is possible. So can I do this? Or do I need to have CentOS 5.2/5.5 on my development desktop as well? Thanks Amit

• Should EC2 server self register or have admin server

  - by hortitude

  I'm creating AWS servers using chef. I am also planning on enabling auto-scaling. While we have automatic monitoring setup already (server density or nagios etc), I was also going to setup the cloud watch alarm for the status check on the server. This led me down the path of trying to decide whether to install the ec2-command-line tools on the server itself (which then requires me to install java on the servers -- despite no other need for Java in our environment) or to possible have an "admin" box that will check periodically for servers and make sure they have their alarms set. I expect this paradigm to carry over to other things we want to configure (perhaps ensuring that termination protection is setup on production servers?). Any thoughts as to why to go one direction or another?

• Can i safely block all ports on my sever

  - by Saif Bechan

  I have a web server running pleks and get attacked a lot every day. I configured a firewall, and there are some predefined services such as www, and ftp, etc. I am planning to block all the ports except for the www port and the PLESK port. When I need ftp or ssh access for example i will open the ports in PLESK and then start to work. Is this a good thing to do or are there some downsides on doing this. There are some ports I am not sure of, such as SMTP,POP3,IMAP, DNS. Can i close these ports or is there no need to do so.

• My uncle is the family historian. We need to host about 5-15 TB of images and video. Any inexpensive

  - by Citizen

  Basically we have hq scans of thousands of old family photos. Plus tons of family video. We want to host them where we can still have total control over the content and restrict access. I'm a php programmer, so the security is not an issue. What is an issue is finding a host to store 10 TB of data and not be paying a ton of money. We really are not planning on a lot of traffic. Maybe 1-10 visitors a day; family only. Kind of like an online library.

• What's up with stat on Mac OS X/Darwin? Or filesystems without names...

  - by Charles Stewart

  In response to a question I asked on SO, Give the mount point of a path, one respondant suggested using stat to get the device name associated with the volume of a given path.

• Implications and benefits of removing NT AUTHORITY\SYSTEM from sysadmin role?

  - by Cade Roux

  Disclaimer: I am not a DBA. I am a database developer. A DBA just sent a report to our data stewards and is planning to remove the NT AUTHORITY\SYSTEM account from the sysadmin role on a bunch of servers. (The probably violate some audit report they received). I see a MSKB article that says not to do this. From what I can tell reading a variety of disparate information on the web, a bunch of special services/operations (Volume Copy, Full Text Indexing, MOM, Windows Update) use this account even when the SQL Server and Agent service etc are all running under dedicated accounts.

• add presence for a remote user to a legacy telephone system?

  - by niko

  we have a small call center that uses an old nortel phone system with analog lines. one of our sales people works from home so her calls do not go through the phone system. this creates a problem at time as the receptionist does not know if she is on the phone or not. we can easily get around this by using instant messenger status but i wanted to ask if there is another way that we can do it so that calls can also be forwarded to her when she is not on the phone. i realize that we can do this with a voip system but we're not planning on upgrading to voip until next year. does anyone know if there is an inexpensive way to add this capability today?

• Internal USB A Female to motherboard 4-pin that mounts internally

  - by rockinthesixstring

  I'm wondering if anyone knows of a product like this but that is physically mountable internally rather than on a cable? I'm planning on building a super low profile "gateway" pc that is dedicated to handling internet traffic in my home. I have a great 1U rackmountable chassis for an ITX motherboard, but I need the hard drive real estate for the additional NIC required to run a gateway (one onboard and one PCI). So the plan is to use a small 8GB USB Jump Drive for the OS inside the box (as to not have one hanging out the back. And although it's racked, I still don't want the jump drive flopping around internally, so I want it fixed somehow. I have an alternative idea where by I use a flush mount zap strap saddle and a zip tie to hold it in place, but that seems kind of like a hack.

• Bandwidth sizing for simultaneous RDP sessions

  - by Gareth Marlow

  We're doing some DR scenario planning which will require up to 150 users to RDP into their desktop machines (mainly running Windows XP) over our VPN. We have a 2mbit uncontended internet connection at the moment but there's scope to upgrade this and also to use a secondary SDSL line to give us more bandwidth. Typical bandwidth figures I've seen suggest to plan for 64kbps per session, which works out to 9.6mbps in total. I'd like to know: Does anyone have any real-world data which would support these estimates? Are there any operational 'gotcha's that we need to be aware of? Thanks!

• CentOS and Snapshots

  - by Jonathan Sampson

  I'm planning on purchasing a virtual-dedicated server today and would like to pass a quick question by the community here before I do. I'm likely going to be getting CentOS, as that seems to be a pretty stable, and popular distro from what I can tell. One of the companies I contacted (MediaTemple) mentioned they provide snapshots just incase I start doing something that could potentially cripple my server - I could always restore the last snapshot. Another company (GoDaddy) said they would provide routine snapshots once a day, week, or month and back it up to a remote FTP for me to download. My question is this, is the "snapshot" capability provided in the OS itself? I'm not super-confident in my abilities yet to manage a server, so this functionality would be very attractive. Or, do I need to pick a host that provides this as an extra addon to the already rendered services?

• Assigning resources to MS Project 2007

  - by adam

  Hi, I'm planning a redesign of a site in Project 2007. I have three developers to hand, all with the same skills. There are about 80 templates to be rendered as part of the redesign, and each template has been added as a project task. Each of these tasks can be done by any of the 3 devs, and each will take a day (with a few exceptions). There is no order in which the tasks must be completed, so there are no predecessor rules. I'd like to be able to assign tasks to a 'Developer' resource group, and for Project to see that three tasks can be done at once (as the group has three resources members) and queue the tasks as such. Googling leads me to Team Assignment, but that appears to be part of Project Server. Surely I can do this in standalone Project? Thanks, Adam

• Incremental backups in Quickbooks 2005

  - by Nathan DeWitt

  My church uses Quickbooks 2005. They have a backup to a 512 MB thumbdrive. They have been backing up about every week for the past 18 months. The filesize of the backups have grown from 14 MB to about 23 MB. I was planning on giving them a 1 or 2 GB thumb drive and calling it a day, but when I dumped this info into Excel and projected out the growth rate, I found that we'll hit 1 GB in July, and 10 GB in about another 18 months, and then 100 GB about 18 months after that. It looks to me like Quickbooks saves all the transactions with every backup. Is there a way to force incremental backups? If this is the way it is, that's fine, but I'd rather not keep buying another order of magnitude of storage space every 18 months. Can I safely delete the previous backups, and just keep the recent 2 or 3 months worth? Thanks.

• Connect a 2.5" (laptop hard disk) SATA hard disk to Desktop PC

  - by Lawliet

  Can I connect a laptop SATA hard disk to Desktop PC? Do I have to use some adapters or I can just plug in SATA power connector and SATA data cable like my Desktop hard disk is connected? I noticed that both laptop and desktop SATA disks use same connectors, but I'm afraid that I might fry my laptop hard disk because the SATA connector has both 12V and 5V voltage (given the fact that laptop hard disks has input voltage of 5V) I bought a all-in-one Modex-to-SATA power adapter and SATA cable and I still don't know what to do. I have read various forums and a lot of people are stating that it's perfectly ok, but some are scaring me that by connecting it so, it fried their hard disk. And some also mentioned cutting the yellow 12V wire if I'm planning to use Modex-to-SATA power. Thanks in advance

• Windows 8.1 fresh install with Windows 8 licence

  - by typ1232

  I purchased Windows 8 online from Microsoft a while ago. Today Windows 8.1 was released as a free update to Windows 8 users over the Windows Store. I was planning to do a fresh install of Windows 8.1 to have a clean system again and UEFI support because I got new hardware since the Windows 8 installation. So my questions are: Where do I get the ISO installation medium for Windows 8.1 64-bit? I tried this microsoft site where I initially got my Windows 8 ISO from, but when entering my Windows 8 key in the Windows 8.1 installer, it says the key is wrong. Even if I get the ISO, will my old key work? I'm concerned because it didn't work in their installer (see previous point) Do they seriously want me to reinstall Windows 8 and after that upgrade to Windows 8.1 through their Store?!

  I'm planning on setting up a small media center to achieve the following: I have multiple users who want to watch satellite channels I want them to be able to change the channel remotely I'm going to buy an external DVB to capture the signal Use some software to stream the channel that is selected I want to have 2 different channels at the same time, I assume I will need two DVB cards Users use VLC or Windows Media Player or whatever to view the channels How can I achieve this? I heard MythTV can do it? I tried to do some research I couldn't find enough information. Note: There's no copyright issue here. I'm streaming Free-To-Air (FTA) channels.

• SSD cache to minimize HDD spin-up time?

  - by sirprize

  short version first: I'm looking for Linux compatible software which is able to transparently cache HDD writes using an SSD. However, I only want to spin up the HDD once or twice a day (to write the cached data to the HDD). The rest of the time, the HDD should not be spinning due to noise concerns. Now the longer version: I have built a completely silent computer running Xubuntu. It has a A10-6700T APU, huge fanless cooler, fanless PSU, SSD. The problem is: it also has (and needs) a noisy HDD and I want to forbid spinning it up during the night. All writes should be cached on the SSD, reads are not needed in the night. Throughout every day, this computer will automatically download about 5 GB of data which will be retained for about a year, giving a total needed disk capacity of slightly less than 2 TB. This data is currently stored on a 3 TB noisy hard disk drive which is spinning day and night. Sometimes, I'll need to access some data from several months ago. However, most times I'll only need data from the last 14 days, which would fit on the SSD. Ideally, I'd like a transparent solution (all data on one filesystem) which caches all writes to the SSD, writing to the HDD only once a day. Reads would be served by the cache if they were still on the SDD, else the HDD would have to spin up. I have tried bcache without much success (using cache_mode=writeback, writeback_running=0, writeback_delay=86400, sequential_cutoff=0, congested_write_threshold_us=0 - anything missing?) and I read about ZFS ZIL/L2ARC but I'm not sure I can achieve my goal with ZFS. Any pointers? If all else fails, I will simply use some scripts to automatically copy files over to the big drive while deleting the oldest files from the SSD.

• Building optimal custom machine for Sql Server

  - by Chad Grant

  Getting the hardware in the mail any day. Hardware related to my question: x10 15.5k RPM SAS Segate Cheetah's x2 Adaptec 5405 PCIe Raid cards Motherboard has integrated SAS raid. Was thinking I would build 2 RAID 10 arrays one for data and one for logs The remaining 2 drives a RAID 0 for TempDB Will probably throw in a drive for OS. Does putting the Sql Server application / exe's on a raid make a difference and is there any impact of leaving the OS on a relatively slow disk compared to the raid arrays? I have 5/6 DBs combined < 50 gigs. With a relatively good / constant load. Estimating 60-7% reads vs writes. Planning on using log shipping as well if that matters. Any advice or suggestions?

• How to configure SCSI hard drives and RAID for Poweredge 2850 web server

  - by Saul

  I'm trying to set up a Poweredge 2850 as a web server, but as a server novice it's causing me some confusion. Its a virgin install so no data to be lost as yet, so I'd like to get the best arrangement for setting up Windows Server 2008. The box will run IIS, a mail and FTP server. The current physical arrangement of the hot swap drives is 1 73GB 3 146GB 5 blank 0 73GB 2 146GB 4 146GB (but flashes green, amber off) When I enter the PERC config screens on boot up I've got Raid Ch- 0 ID 0 ONLIN A00-00 1 ONLIN A00-01 2 ONLIN A01-00 3 ONLIN A01-01 4 HOTSP I think that drives 0 and 1 are set to RAID 1 and drives 2 and 3 are also set to RAID 1, certainly I can see 2 logical drives, both raid 1 of 69880MB and 139900MB Now what I think I am getting here is that the 2 73GB drives mirror each other and the 2 146GB drives mirror 2? so by my noob thinking if a drive fails I can pull it, insert and new one and it will reduplicate from its matching pair? I think the flashing amber probably indicates a failing drive in slot 4, should that just be binned? What confuses me coming from a home user XP background is that when I load up Windows Server 2008 OS under my computer I only see a C drive of about 70GB capacity. i.e wheres the 146GB drive? Any advice appreciated

• How to benchmark apache/nginx setup

  - by Saif Bechan

  I am planning to setup nginx as reverse proxy. I will have apache to deliver my dynamic content, and nginx will deliver the static content. My configuration i have now is just Apache with fastCGI. This gives me no configuration problems and runs great. After I have set up nginx I want to run some benchmarks to see if I really got some performance increases, else i will switch back. Does anyone know how I can benchmark this type of setup? Or maybe someone did this already and have some canned results, I will be glad to hear them.
