  • How to convince non-programmer his notions about computers are wrong?

    - by Suma
    Recently I came across a question about 64b on SuperUser for which the accepted answer seemed like a complete nonsense to me. I made two comments pointing out obvious mistakes. To my perplexion, the comments had an effect of the poster of the answer being alienated. I have no idea how could I convince him he is wrong, as he does not seem to understand the basics of the problem. He seems to be mixing concepts like bus size and address size - see the pearl sentence "it will allow you to address all of your RAM because your processor is reading from your RAM in 64 bit words.". The poster asks me to provide proves of my claim by quoting a respectable source, but I have no idea where to find such source, as I doubt anything I would consider relevant would be relevant for him (it would be probably too technical). I think this instance can serve as an illustration of communication problems between programmers and users (and to certain extent even to any expert vs. non-expert communication). How should a programmer handle a communication like this, so that is does not become a useless quarrel?

  • easiest way to automate all software installations for new users/computers?

    - by sorrrydoctorforlove
    Basically, for every new user we have about 30 different installers that all need to be run manually after an install of windows which is tedious/time consuming. We can't simply ghost/image the computers as they come because of the wide variety of hardware being used (all laptops). What would you suggest to run through all the installers automatically without requiring me to sit and click 'next'.. 'next'.. 'continue'.. 'no dont install msn toolbar please'?

  • Auto backup a user folder to a usb when usb is plugged in

    - by Azztech Computers
    I'm a computer technician and help customers everyday with their computers and smartphones and have a really basic (i think) request but dont know how to go about it. Customer always come in with broken phones, water damage, needing updates, or just want me to backup their information. I currently have a program that i use when i backup their computers it backups their iOS folder C:\Users\USER\AppData\Roaming\Apple Computer\MobileSync\Backup but what i want is a quick easy way to do this in customers houses. What i require is a way when i plug in a USB drive it AUTOMATICALLY searches for the folder and starts transferring the folder to a predefined folder on the USB drive. This was I can just plug it in and begin work on their computer or phone without the risk of losing their information. I'm sure there is a .bat/.ini file i could use but wondering if someone has already done this or something similar as I would need it to search all the USER folders not just the one I'm logged into. Thanks in advance

  • Good ways to restart all the computers in a remote cluster?

    - by vgm64
    I have a cluster that I manage and from time to time I get emails from each node (and head node) begging to be restarted after an automatic upgrade. Currently, my best solution so far is a shell script like: $> cat cluster_reboot.sh ssh [email protected] reboot ssh [email protected] reboot ssh [email protected] reboot ssh [email protected] reboot ssh [email protected] reboot ssh [email protected] reboot I end up just typing the root password six times, but it works, I guess. Is there a better way? Can I force the head node to reboot the computers for me?

  • UPS - Two computers - How to get them to both shutdown when battery is low?

    - by hamlin11
    Short Version: How do I get 2 computers to shutdown when a UPS battery gets low? Long Version: I have an APC UPS, the RS 1500. It has a USB cord that goes into my main dev computer. My dev computer will shutdown when the battery gets low. However, in addition, I have now hooked up a database server to the same UPS. How can I have that database server also know that it needs to shut down when the battery gets low?

  • How to maximise performance in computers connected into LAN via Gigabit ethernet router?

    - by penyuan
    Our group is setting up a server (which might just be a NAS, but we're not sure yet), which shares files, so that it connects to all other computers in the room (about 10 of them). I am thinking just hooking all of them up via a gigabit router/switch. Is there anything I should watch out for, in terms of cables, connections, or the connection capabilities of each computer in the network? For instance, I don't want a slow computer in the LAN to slow down everyone else's connection, etc., etc. Thanks for the education.

  • Computers "applying computer settings" for a long time on start-up...why?

    - by tombull89
    Hello. Might be a bit of a slong shot but I'm stumped, along with the ICT Manager for the school I'm working it. In one of the IT rooms when you switch a computer on it will boot through BIOS fine, but when it gets to "applying computer settings" it can hang for a long time (~15 minutes). If you unplug the computer from the network it starts up fine, gets to the login screen, then you can plug the network cable in and it will work fine. I don't think it's anything to do with the fact we've been coming close to running out of IP addresses or a problem with our DHCP. Microsoft KB says apply the latest service pack, which we've done, and check a service. Servers and domian controllers are S2003, Computers and Desktops are XP. Does anybody have any thoughts on what to try?

  • Why does the Mac OS X (10.6) Finder stop being able to connect to Windows computers?

    - by Drarok
    We have one Mac (a MacBook Pro Unibody) amongst our Windows machines which connects to the "server" (actually a Dell running Windows XP Pro) to access documents. This works just fine most of the time, but sometimes after waking from sleep, it cannot connect to any Windows computer on the network. There are no errors (nor even any messages) in the Console application when attempting to connect either by the Finder's network browsing, nor when using the "Connect To Server" menu. I have tried "Relaunch" on Finder, toggled File Sharing, disabled and re-enabled the Airport, but nothing makes the Mac able to connect again until I reboot it! Other computers can connect to the machines, so it is definitely the Mac at fault. Are there any workarounds that anyone has found? Is there perhaps a way to re-start the samba client?

  • How can I load one image over network to multiple computers on boot?

    - by user754730
    A few years ago I saw this in a company but I don't know how it was built. There was 1 Computer (I don't know if Windows Server or plain Windows 7 - the server) and 3 other computers (Windows 7 - the clients). As soon as the Windows 7 clients were started, they all started up the same image (Don't know if the same image file or just the same state) over network and were able to work on the computer. As soon as the machine was shutdown, all the changes made to the system were erased. How could I build a system like this so I have 1 image file which I keep up to date and then feed it to the other machines in my network? It would look this this basically:

  • Not getting my normal internet speed but my other computers can?

    - by Dennis
    I have Comcast Xfinity and I cannot reach anywhere near my promised speed. My family desktop which is hardwired into the router reaches to 60Mbps and so do my parents computers and my brothers. I cannot seem to get anywhere close to it, I know with being wireless I won't reach it, but I should at least get somewhere close. I can only pull 6Mbps and thats terrible for what I should be receiving. Any clue what could be wrong here? Edit: I have 100% signal and I'm not behind any walls

  • How to share Opera extensions preferences between my two computers ?

    - by Riduidel
    Well, the title is quite unambiguous. However, let me clarify it even more. Starting with Opera 11, there now are Opera extensions, which are compliant to W3C widget specification. This allows us to use it on whichever browser supports their (well, currently, only Opera does). Anyway, suppose I have two computers, each one using Opera. How could I possibly synchronize used extensions and their preferences ? With Opera Link ? I didn't saw any kind of extension sharing in it With Dropbox/any other file sharing application ? If so, how could I do that ?

  • Can anyone recommend how to fix sore "sides" from overuse of computers? (some kind of RSI)

    - by MGOwen
    I have to use computers for 9+ hours per day (no suggestions about 'use your computer less!' please). I get various kinds of RSI: a little soreness in the hands and wrists, but that's not a big deal compared my main problem: Pain in the sides of my body, under my arms and down the sides of my torso. Driving worsens it. Exercise doesn't seem to help (maybe I need a special exercise). It could be posture related, but I haven't found a way to fix that. Has anyone else experienced this? I find lots of people complaining about more typical kinds of RSI, but not like mine. I am hoping someone with experience can recommend an exercise, treatment, or adjustment in how I use my computer.

  • Nginx works on my linux machine but is not accessible from other computers in my local network

    - by crooveck
    In my LAN network I have a server with Scientific Linux (RedHat or Fedora based distro), I've done yum install nginx but the welcome page is not accessible from other computers in my network. When I do telnet open localhost 80 and then GET / HTTP/1.0 I get some html code from nginx, so it's running for sure. But when I want to connect remotly, doing telnet open 192.168.3.130 80 I get: Trying 192.168.3.130... telnet: Unable to connect to remote host: No route to host So I assume that there is something wrong with my network settings, maybe iptables or something else? Next step, I turned off iptables: service iptables stop and it helped, now I can connect remotely using telnet. So I think, I need to fix my iptables rules. I did some googling and found this rule -A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT but it still didn't allow me to connect remotely when iptables is up. Can someone please help me setting a proper iptables configuration?

  • How does communication between 2 computers in a single network happen?

    - by learner
    Lets say I and my friend connect our computers with a LAN cable. I ping my friend with his IP address. How does it work? Since we are in the same network, we don't even need IP addresses, do we? Isn't IP addressing only relevant in case of inter-network communication? What will the ping command do with his IP address? How will it eventually find his physical address (NIC address)? (no ARP here, because that would involve a router at the edge of the network, which doesn't apply here). Am I wrong somewhere?

  • Starting over and new to Ubuntu

    - by 2funnyyone
    We have been having repeated problems with our interent service and using windows xp & sp3 (users and premissions) I see no need for them. I started with computers long before windows. Every since sp 3 come out in 2009 I have had nothing but problems. I have lost so many computers to virius and trojans, we just stack them up. We are with Qwest/ Century link which is using advertising servers which I think is causing the problem. All the computers are networked together which is not how I set them up. I beleive Century link is networking them through assignment of a domain for our home. This causes all the computers to crash twice. This is getting expensive. We tried buying new harddrives but reinfect with hours of connecting to internet. I also beleive the modem, router and all computers are infected. I put combofix on this one and that is the only reason we are still online with this laptop. I am afraid to install new equipment because my partner and I are on SSDI and this cost a lot. I go to school at UOP and had to run off a flash and reboot this laptop to recovery every other day or so, this pass month. New plan is: We are getting ready to install new equipment but afraid to reinfect again. Need help to install new equipment. The plan is to use current internet services from Qwest/ now Century Link. The list of New equipment in order: Century link wireless modem is ZyXEL PK5000Z with 4 direct connect Ethernet ports Next Dell Optiplex 210L ( used auction purchase ) 2 gb ram 80 g hard drive Ubuntu 11.10 operating system Next Wireless D-Link router WBR-1310 with 4 direct connect Ethernet ports OK-------- Purchased Dell OEM disk for Repair or Reinstalling Windows XP Professional Operating system (2 roommates as well) All infected computers are Dell desktops or laptops with XP Pro Also purchasing Ubuntu 12.04 for 3 computers. We like the way it runs but still learning it. Questions 1] How do we fdisk the infected computers without infecting new system. We have Dos disks, but none have floppy dish drive. We do have a new floppy disk drive and usb adapter we purchased from Amazon. 2] We are thinking Avast internet security because of the boot scan. We want all software loaded before reconnecting. We can manually load our internet provider information. We purchased StopZilla $100 for 5 computers, but not sure that is what we need. But need how to setup ports security and services we will need. Really lost at this part. So we are safe when we go back on the internet. 3] Want to connect reloaded fdisk systems to router as public connection and no sharing. Do not want to network all computers. 4] Want parental/ ownership control from Ubuntu system for internet connection (Children and friends). Do we restrict at the modem and/ or router? Any help would be a blessing. I do not want to go alone on this anymore.

  • How do I connect two computers with a LAN cabel?

    - by John
    I have two machines - Windows XP and a laptop using Windows 7. I connected them with a WLAN cable. On the Windows XP machine, I set the IP address to 192.168.0.10. On the Windows 7 laptop, I set the IP address to 192.168.0.20. The laptop can see the Windows XP machine, but Windows XP machine cannot see the Windows 7 machine. But this does NOT concern me. I want to move the files from my desktop (Windows XP) to Windows 7 (laptop). That's why I'm going through all this. The problem is that when I try to connect from Windows 7 to Windows XP machine, I get this window: I don't understand what username/password is needed. I use none on the Windows XP machine. I tried all usernames - no success. Please explain in deep details how to solve my problem so I can connect to my Windows XP machine. EDIT: Maybe this can help: the Windows XP machine is named 'I' and '???????? III' is the name of the laptop. Both computers share one workgroup - WORKGROUP.
