  • Question about Installing an Intel E5300 CPU.

    - by jeff
    Can I re-use my heatsink/fan that is currently on the motherboard with this new Intel e5300 CPU ? I know both CPUs are socket 775 based CPUs. I have a 2.4 GZ single core Intel chip currently. Also would I be able salvage the thermal paste or should I just buy new paste?

  • What is the best Linux filesystem for MySQL (InnoDB)?

    - by Continuation
    I tried to look for benchmark on the performances of various filesystems with MySQL InnoDB but couldn't find any. My database workload is the typical web-based OLTP, about 90% read, 10% write. Random IO. Among popular filesystems such as ext3, ext4, xfs, jfs, Reiserfs, Reiser4, etc. which one do you think is the best for MySQL?

  • System Requirements of a write-heavy applications serving hundreds of requests per second

    - by Rolando Cruz
    NOTE: I am a self-taught PHP developer who has little to none experience managing web and database servers. I am about to write a web-based attendance system for a very large userbase. I expect around 1000 to 1500 users logged-in at the same time making at least 1 request every 10 seconds or so for a span of 30 minutes a day, 3 times a week. So it's more or less 100 requests per second, or at the very worst 1000 requests in a second (average of 16 concurrent requests? But it could be higher given the short timeframe that users will make these requests. crosses fingers to avoid 100 concurrent requests). I expect two types of transactions, a local (not referring to a local network) and a foreign transaction. local transactions basically download userdata in their locality and cache it for 1 - 2 weeks. Attendance equests will probably be two numeric strings only: userid and eventid. foreign transactions are for attendance of those do not belong in the current locality. This will pass in the following data instead: (numeric) locality_id, (string) full_name. Both requests are done in Ajax so no HTML data included, only JSON. Both type of requests expect at the very least a single numeric response from the server. I think there will be a 50-50 split on the frequency of local and foreign transactions, but there's only a few bytes of difference anyways in the sizes of these transactions. As of this moment the userid may only reach 6 digits and eventid are 4 to 5-digit integers too. I expect my users table to have at least 400k rows, and the event table to have as many as 10k rows, a locality table with at least 1500 rows, and my main attendance table to increase by 400k rows (based on the number of users in the users table) a day for 3 days a week (1.2M rows a week). For me, this sounds big. But is this really that big? Or can this be handled by a single server (not sure about the server specs yet since I'll probably avail of a VPS from ServInt or others)? I tried to read on multiple server setups Heatbeat, DRBD, master-slave setups. But I wonder if they're really necessary. the users table will add around 500 1k rows a week. If this can't be handled by a single server, then if I am to choose a MySQL replication topology, what would be the best setup for this case? Sorry, if I sound vague or the question is too wide. I just don't know what to ask or what do you want to know at this point.

  • Do Hyper-V guests see multiple CPUs (sockets) or multiple CPU cores when assigned more than 1 vCPU?

    - by Filip Kierzek
    I have SQL Server 2008 Express running on Hyper-V based virtual machine with two vCPU-s. I've just been reading up on SQL Server 2012 Express and noticed that it's CPU is "Limited to lesser of 1 Socket or 4 cores" (http://msdn.microsoft.com/en-us/library/cc645993(v=SQL.110).aspx) My question is how do the SQL Server 2012 limits on CPUs/Cores translate into vCPU-s? Are they "processors" or are they "cores"?

  • Are Time Machine backups secure?

    - by Leandro Ardissone
    I have my Time Machine backups on an external disk (WD My Passport with no hardware encryption) and I'm worried if the data stored on the disk is safe in case somebody steals it and connect it to any Mac/PC. Does any Mac can browse the Time Machine backups? Or are they encrypted in any way? If no, is there a way to improve security of the backups, should I buy a hardware encryption based HD? Thanks.

  • TCP/IP & throughput between FreeNAS (BSD) server & other LAN machines

    - by Tim Dickerson
    I have got a question for someone that knows BSD a bit better than me that are in regards to my LAN setup at home/work here outside Chicago. I can't seem to fully optimize my network's (LAN) thoughput via my FreeNAS (BSD based) file server. It runs with the latest FreeBSD release which is modified to support several protocols for file transfers and more. Every machine that is behind my Smoothwall (Linux based) router is on the usual 192.168.0.x subnet and for most part works just fine. Behind the Smoothwall box, all machines are connected to a GB HP unmanaged switch. I host a large WISP here and have an OC-3 connection here at home/work and have no issues with downloading/uploading from/to the 'net'. My problem is with throughput. When I try and transfer large files...really any for that matter..between any of the machines to/and from the FreeNAS server via FTP, the max throughput I can achieve say between a Win 7 or a Linux box is ~65Mbit/sec. All machines are running Intel Pro 1000 GB NIC's and all cable is CAT6. Each is set to 'auto negotiation' and each shows 1500 MTU Full Duplex @1GB so I know the hardware is okay. I have not adjusted the MTU on any machine as I understand it to be pointless unless certain configurations are used (I assume I am not one of those). My settings for the FreeNAS machine are the following: # FreeNAS /etc/sysctl.conf - pertinent settings shown kern.ipc.maxsockbuf=262144 kern.ipc.nmbclusters=32768 kern.ipc.somaxconn=8192 kern.maxfiles=65536 kern.maxfilesperproc=32768 net.inet.tcp.delayed_ack=0 net.inet.tcp.inflight.enable=0 net.inet.tcp.path_mtu_discovery=0 net.inet.tcp.recvbuf_auto=1 net.inet.tcp.recvbuf_inc=524288 net.inet.tcp.recvbuf_max=16777216 net.inet.tcp.recvspace=65536 net.inet.tcp.rfc1323=1 net.inet.tcp.sendbuf_inc=16384 net.inet.tcp.sendbuf_max=16777216 net.inet.tcp.sendspace=65536 net.inet.udp.recvspace=65536 net.local.stream.recvspace=65536 net.local.stream.sendspace=65536 net.inet.tcp.hostcache.expire=1 From what I can tell, that looks to be a somewhat optimized profile for a typical BSD machine acting as a server for a LAN. I might be wrong and just wanted to find out from someone that knows BSD better than I do if indeed that is ok or if something is out of tune or what. Are there other ways I would find better for P2P file transfers? I honestly do not know what I SHOULD be looking for with respect to throughput between the NAS box and another client when xferring files via FTP, but I am told that what I get on average (40-70MB/sec) is too low for what it could be. I have thought about adding another NIC in the FreeNAS box as well as the Win7 machine and use a X-over cable via a static route, but wanted to check with someone first to see if that might be worth it or not. I don't know if doing that would bypass the HP GB switch and allow for a machine to machine xfer anyways. The FTP client I use is: Filezilla and have tried both active and passive modes with no real gain over each other. The NAS box runs ProFTPD.

  • Quick-n-Easy way to remove outdated ActiveDirectory users?

    - by Jason Taylor
    We have around 70 current employees, but 178 accounts in ActiveDirectory. The prior administrators never removed old accounts, and sometimes they weren't even disabled. As it is, I am considering manually reviewing each account to determine if it can be removed. Is there an easier way to remove accounts based on a condition? Such as, remove (or at least disable or flag in some way) users that haven't logged in within the last month or so?

  • How do software .dmg files mount or work in OS X?

    - by ymasood
    I am a new Mac user and have an iMac. Coming from the Windows world where everything is installer based, OS X seems to mount .dmg files and run them. I've seen this happen prior to an install and later it requests us to move an icon to the Applications folder. Could someone help me unclutter the install process on OS X. What or how does it work? Thanks in advance!

  • few questions on packet sniffer/analyzer

    - by user37652
    I have few questions about packet sniffer. I'm using a zyxel p-600 series modem and a hub to distribute the internet connection. Can I use a packet sniffer here to determine if the user is downloading something? Can I determine if the user is downloading a file based on the modem alone.(The lights blink faster) Is there an application that I could use for the modem or the hub to limit or avoid direct downloads. Details: OS: Ubuntu 9.10 and Windows 7

  • iis7 bandwith throttling for downloads via iis media services?

    - by MikeJ
    I am looking after a sever that is managing the downloads of software updates released by the company where I work. The throttle in IIS7 seems to limit the total rate and not the rate each individual download gets. I was thnking on installing media services, adding .zip as a type and then throttling the individual connection rate based on what I read. Is this how this sort of thing is done with IIS7?

They DO know how to enter an admin's credentials when prompted.

  • Online Free Accounting Software

    - by Ngu Soon Hui
    I am looking for a free, online-based accounting application, something like a web-version of QuickBooks or MS Money. The catch here is that, of course, it needs to be free. I don't know if any company is philanthropic enough to offer this kind of service to individual users.

  • Monitor uSWGI via Nagios: invalid socket

    - by webjay
    I'm trying to monitor uSWGI via Nagios, but according to uWSGI I have specified an invalid socket. The socket path I got from the JSON config file which also says chmod-socket: 666 so I have a hunch that the problem is permission based. The socket file is owned by www-data who I don't want to tinker with, so any other ways? uwsgi --socket=/tmp/app.sock --nagios detected binary path: /usr/local/bin/uwsgi UWSGI UNKNOWN: you have specified an invalid socket ls -l /tmp/app.sock srw-rw-rw- 1 www-data www-data 0 2012-10-26 17:00 /tmp/app.sock

  • Timezone reset on Amazon AMI update

    - by Jeff
    I have a server set up through Amazon AWS. It's Amazon's RHEL-based AMI. When I initially booted up the machine, I set the proper timezone by creating a symlink: ln -sf /usr/share/zoneinfo/America/Los_Angeles /etc/localtime This works just fine, but whenever Amazon provides an update to their AMI the timezone automatically reverts to UTC. Is there a way around this or does it have to be manually set after each update?
