    - by Austin
    Ok so here is more descriptions, I REALLY NEED HELP! I installed Ubuntu on a disk (unsure of v. I can't check.. Computer is broke :/ ) I then burned the disk I restarted computer pressed f12 blah blah it came up, I pressed enter for English, I plugged an Ethernet card in for better connection, and then started the installation.... I did the basics, and I entered a host name, and a user name and pass all that, when it came to partition page, I presse enter for no and then it went back to the installation page, I pressed install again, and it brought me back, so I selected yes , it loaded an it asked what software to instal I selected sh ( it was first option and I didn't know which to do ) so after everything finished loading, my disk was ejected the process finish, I run my computer and it opens up in log in page on cmd script I didn't know it, so I ran disk again makin a user and pass to remember.... Going back to login thing I logged in, and all it did was say my username... I didn't know what to do from there, I looked online found nothing but grub stuff, so I went to "Advanced Ubuntu options" and then "(Recovery Mode) and went to update grub...

  • Building a computer for the first time from scratch - will this really work?

    - by Nike
    Hey there. I'm building my own computer, and i just finished picking out all of my parts. Now i just want to be sure it'll all work before i order it. I'm mean specifically if the RAM & Graphic card will fit on the motherboard i chose. Below is a list of all parts. I'm sorry, i selected the parts from a Swedish website so it might be hard to understand some parts. Google Translate will help ;) I really appreciate any help/suggestions. Thanks in advance! :) Oh, and here's the parts i mentioned: EDIT: As i'm not allowed to post more than one link here, i'll just link to my homepage: http://nike1.se/c/ I know i didn't choose the most expensive parts, but this won't be my primary computer. I'm only going to use this one for testing purpose, if that makes any sense. I'm sorry for my english, i'm just so tired now. Haha! Once again, thanks in advance! :)

  • IPv6 routing to another interface

    - by Robert
    I'm trying to get an IPv6 enabled router to forward data from one interface to the other and I'm having issues. When following this example (http://www.cisco.com/en/US/tech/tk872/technologies_configuration_example09186a0080ba6106.shtml) I am able to get full connectivity between all 3 routers in my simulator. However when I try to use only 1 router; I can't get connectivity to the other interfacs on the same router. My PC is directly attached to FA 0/1 and it can ping the router's interface. However it can not ping any other interface on the router(which unless I'm missing something it should be able to do). The router on the other hand can ping everything. I thought static routes might help; but the router already has routes for everything. I'm thinking the packet should come in; router looks up the destination in it's ipv6 routing table and then realizes it's for itself, and should respond. I thought maybe it couldn't respond directly; so I tried pinging a device like 2001:0000:0000:1000::2, but i don't get a response. I'm running on IOS 12.4. I'm missing something(hopefully simple), but I just can't see what it is. With only 1 router; how do I enable my PC to talk to the other subnets? Thank you in advance, Robert Topology: R1 FA 0/0: 2001:0000:0000:0000::1/52 FA 0/1: 2001:0000:0000:1000::1/52 FA 1/0: 2001:0000:0000:2000::1/52 Loopback 0: 2001:0000:0000:3000::1/52 PC: 2001:0000:0000:2000::2/52 PC plugs directly into FA 1/0 on the router. --- Configuration --- ipv6 cef ipv6 unicast routing interface Loopback0 no ip address ipv6 address 2001:0000:0000:3000::1/52 ipv6 enable ! interface FastEthernet0/0 no ip address duplex auto speed auto ipv6 address 2001:0000:0000::1/52 ipv6 enable ! interface FastEthernet0/1 no ip address duplex auto speed auto ipv6 address 2001:0000:0000:1000::1/52 ipv6 enable ! interface FastEthernet1/0 no ip address duplex auto speed auto ipv6 address 2001:0000:0000:2000::1/52 ipv6 enable --- end of config --- --- routing table --- IPV6Lab#show ipv6 route IPv6 Routing Table - 10 entries Codes: C - Connected, L - Local, S - Static, R - RIP, B - BGP U - Per-user Static route I1 - ISIS L1, I2 - ISIS L2, IA - ISIS interarea, IS - ISIS summary O - OSPF intra, OI - OSPF inter, OE1 - OSPF ext 1, OE2 - OSPF ext 2 ON1 - OSPF NSSA ext 1, ON2 - OSPF NSSA ext 2 C 2001:0000:0000::/52 [0/0] via ::, FastEthernet0/0 L 2001:0000:0000::1/128 [0/0] via ::, FastEthernet0/0 C 2001:0000:0000:1000::/52 [0/0] via ::, FastEthernet0/1 L 2001:0000:0000:1000::1/128 [0/0] via ::, FastEthernet0/1 C 2001:0000:0000:2000::/52 [0/0] via ::, FastEthernet1/0 L 2001:0000:0000:2000::1/128 [0/0] via ::, FastEthernet1/0 C 2001:0000:0000:3000::/52 [0/0] via ::, Loopback0 L 2001:0000:0000:3000::1/128 [0/0] via ::, Loopback0 L FE80::/10 [0/0] via ::, Null0 L FF00::/8 [0/0] via ::, Null0 --- end of routing table ---

  • After update UBUNTU 12.04 changes wired interface from eth0 to eth1, network configuration fails

    - by Don McLaren
    I have been running UBUNTU 12.04 for a couple of months on this system with no problems. After a recent update, the bootup fails to define the wired network interface as eth0, so the default network configuration fails. ifconfig -a shows eth1 instead, as unconfigured. Booting from CD works OK, configures eth0 as normal. Solution: sudo NetworkManager The network manager figures out the situation, and configures eth1 Question: Where did this problem come from all of a sudden?

    Earlier this week we asked you to share your tips and tricks for setting up a novice-proof computer; read on to see how your fellow readers ensure friends and relatives have a well protected computer. Image available as wallpaper here. If you only listen to a single bit of advice from your fellow readers, let that advice be the importance of separate and non-administrative user accounts. Grant writes: I have two boys, now 8 and 10, who have been using the computer since age 2. I set them up on Linux (Debian first, now Ubuntu) with a limited rights account. They can only make a mess of their own area. Worst case, empty their home directory and let them start over. I have to install software for them, but they can’t break the machine without causing physical damage (hammers, water, etc.) My wife was on Windows, and I was on Debian, and before they had their own, they knew they could only use my computer, and only logged in as themselves.

  • The Evolution of Computer Keyboards

    - by Jason Fitzpatrick
    While the basic shape of keyboards has remained largely unchanged over the last thirty years, the guts have undergone several transformations. Read on to explore the history of the computer keyboard. ComputerWorld delves into the history of the modern keyboard, including the heavy influence IBM’s extensive keyboard research on early keyboards: As far as direct influences on the modern computer keyboard, IBM’s Selectric typewriter was one of the biggest. IBM released the first model of its iconic electromechanical typewriter in 1961, a time when being able to type fast and accurately was a highly sought-after skill. Dag Spicer, senior curator at the Computer History Museum, notes that as the Selectric models rose to prominence, admins grew to love the feel of the keyboard because of IBM’s dogged focus on making the ergonomics comfortable. “IBM’s probably done more than anyone to find [keyboard] ergonomics that work for everyone,” Spicer says. So when the PC hit the scene a decade or two later, the Selectric was largely viewed as the baseline to design keyboards for those newfangled computers you could put in your office or home. Hit up the link below to continue reading about how the Selectric influenced keyboards throughout the 1980s and what replaced the crisp clacking of early IBM-styled models. 6 Ways Windows 8 Is More Secure Than Windows 7 HTG Explains: Why It’s Good That Your Computer’s RAM Is Full 10 Awesome Improvements For Desktop Users in Windows 8

  • Question about whether I should pursue minors or work towards a masters [closed]

    - by user75493
    I'm a sophomore about to go into my Spring semester in a few weeks and I am trying to decide some major things that will affect the next few years of my life and was looking for some guidance/advice. I'm currently working towards a Bachelors in Computer Science and my question was whether I should minor in Corporate Strategy and Math or just work towards a Masters in Computer Science? I was wondering if employers are more looking for Masters degrees in Computer Science or if those minors could be beneficial to me. Some things that may affect responses: I already have all my other requirements filled for graduating except my Computer Science classes, I've already had an internship this past summer and am already hearing back from several companies about internships for this upcoming summer. Thanks in advance! - Alex

  • Would having an undergraduate certificate in Computer Science help me get employed as a computer programmer? [on hold]

    - by JDneverSleeps
    I am wondering how would employers perceive the Universtiy Certificate in Computing and Information Systems offered by Athabasca University (a distance education institution... The university is legit and accredited by the Government of Alberta, Canada). I already have a BSc in Statistics from University of Alberta (a classic brick and mortar public university in Alberta, Canada)...so I can state in my resume that I have a "university degree"..... Luckily, I was able to secure a very good employment in my field after the graduation from the U of A. The main reason why I am interested in taking the certificate program through Athabasca is because knowing how to program can increase the chance for promotion in my current job. I also believe that if something turns out bad in my current job and if I ever need to look for a new place to work, having the certificate in computer science will help me get employed as a computer programmer (i.e. my choice for the new job wouldn't be restricted to the field of Statistics). Athabasca University is claiming that the certificate program is meant to be equivalent to the undergraduate minor in computing science. I carefully looked at the certificate's curriculum and as far as I am concerned, the certificate program does have the same level of rigour as the undergraduate minor in Computer Science programs offered by other Canadian universities. I am also confident that the certificate program will get me to pick up enough skills/background to start a career as a computer programmer. The reasons why I am not 100% sure on getting the certificate is worth the tuition are: Athabasca University is a distance education institution (accredited by government but still) The credential that I will receive is "university certificate", not a "undergraduate degree" Do you think it's a good idea for me to pursue the certificate, given the two facts above? again, I already have my Bachelor's degree - although it is not in CS Thanks,

  • Virtual network interface in Mac OS X

    - by Hans Doggen
    I know that you can make a virtual network interface in Windows (see here), and in Linux it is also pretty easy with ip-aliases, but does something similar exist for Mac OS X? I've been looking for loopback adapters, virtual interfaces and couldn't find a good solution. You can create a new interface in the networking panel, based on an existing interface, but it will not act as a real fully functional interface (if the original interface is inactive, then the derived one is also inactive). This scenario is needed when working in a completely disconnected situation. Even then, it makes sense to have networking capabilities when running servers in a VMWare installation. Those virtual machines can be reached by their IP address, but not by their DNS name, even if I run a DNS server in one of those virtual machines. By configuring an interface to use the virtual DNS server, I thought I could test some DNS scenario's. Unfortunately, no interface is resolving DNS names if none of them are inactive...

  • How do I edit an interface builder object programmatically?

    - by Evelyn
    I created a label using Interface Builder, and now I want to set the background color of the label using code instead of IB's color picker. (I want to do this so that I can define the color using RGB and eventually change the colorspace for the label.) I'm in cocoa. How do I edit the attributes of an IB object using code? My code looks like this: //.h file #import <UIKit/UIKit.h> @interface IBAppDelegate : NSObject { UILabel *label; } @property (nonatomic, retain) IBOutlet UILabel *label; @end //.m file #import "IBAppDelegate.h" @implementation IBAppDelegate @synthesize label; (memory stuff...) @end

  • Changing property type in class that implements interface with object type property.

    - by used2could
    I know the title is a bit confusing but bare with me. (I'm up for suggestions on a new title lol) I'm writing a TemplateEngine that will allow me to use my own markup in text based files. I'm wanting to add controls as plugins as the application matures. Currently i've got a structure like the following: interface IControl string Id object Value class Label : IControl string Id string Value class Repeater : IControl string Id List<IControl> Value Now you'll see the strange part right away in the Repeater class with the Value property. I was hoping that having the Value type as object in the interface would allow me the flexibility to expand the controls as i go along. The compiler doesn't like this and for good reason i guess. Does anyone have any suggestions how to accomplish this? Note: Please don't go into suggesting things like use Spark View Engine for templating. There is a reason i'm creating extra work for myself.

  • Spring.net - how to choose implementation of interface in runtime ?

    - by rouen
    Hi, in all examples of spring.net IoC i can see something like this: interface IClass; class ClassA : IClass; class ClassB : IClass, and then in config.xml file something like [object id="IClass" type="ClassB, Spring.Net.Test" /] but, i really need to do something like this: in config file there will be more implementations if interface: [object id="IClass" type="ClassA, Blah" /] [object id="IClass" type="ClassB, Blah" /] and then, in runtime i choose from them, something like this: IClass c = [get me all implementations of IClass, and choose the one with GetType().FullName == myVariableContainingFullTypeNameOfObjectIWant] how can i do something like this please, i cant google anything for hours.... many thanks !

  • How can I display a hidden view in Interface Builder which is on a unattached monitor?

    - by Brennan
    I am using Interface Builder to work on NIBs and one of the NIBs must have a view on my external monitor which is not attached because I cannot see it on my MacBook. I have had this problem with editing iPad NIBs which I work on with my larger external monitor. For some reason Interface Builder is not detecting that there is now just one screen and not pulling this view onto this monitor. There has to be a way to get this back into the visible space so that I can work on it. I have tried double clicking on the view icon in the organizer which normally brings the view forward but it is not coming into view. What can I do? Is this really a bug that has been around this whole time?

  • how to develop a program to minimize errors in human transcription of hand written surveys

    - by Alex. S.
    I need to develop custom software to do surveys. Questions may be of multiple choice, or free text in a very few cases. I was asked to design a subsystem to check if there is any error in the manual data entry for the multiple choices part. We're trying to speed up the user data entry process and to minimize human input differences between digital forms and the original questionnaires. The surveys are filled with handwritten marks and text by human interviewers, so it's possible to find hard to read marks, or also the user could accidentally select a different value in some question, and we would like to avoid that. The software must include some automatic control to detect possible typing differences. Each answer of the multiple choice questions has the same probability of being selected. This question has two parts: The GUI. The most simple thing I have in mind is to implement the most usable design of the questions display: use of large and readable fonts and space generously the choices. Is there something else? For faster input, I would like to use drop down lists (favoring keyboard over mouse). Given the questions are grouped in sections, I would like to show the answers selected for the questions of that section, but this could slow down the process. Any other ideas? The error checking subsystem. What else can I do to minimize or to check human typos in the multiple choice questions? Is this a solvable problem? is there some statistical methodology to check values that were entered by the users are the same from the hand filled forms? For example, let's suppose the survey has 5 questions, and each has 4 options. Let's say I have n survey forms filled in paper by interviewers, and they're ready to be entered in the software, then how to minimize the accidental differences that can have the manual transcription of the n surveys, without having to double check everything in the 5 questions of the n surveys? My first suggestion is that at the end of the processing of all the hand filled forms, the software could choose some forms randomly to make a double check of the responses in a few instances, but on what criteria can I make this selection? This validation would be enough to cover everything in a significant way? The actual survey is nation level and it has 56 pages with over 200 questions in total, so it will be a lot of hand written pages by many people, and the intention is to reduce the likelihood of errors and to optimize speed in the data entry process. The surveys must filled in paper first, given the complications of taking laptops or handhelds with the interviewers.

  • How can I write cocoa bindings as code instead of in the Interface Builder?

    - by johnjohndoe
    In my modell got an NSMutableArray that keeps track of a changing number of elements. In my view I got a NSTextField that shows the number of elements. The view gots unarchived from the nib file and alloc/inits the modell. Therefore it knowns about the modell and the contained array. I established the connection as follows. In the Interface Builder at the textfield I added a Cocoa Binding "path" like this: myModell.myArray.@count. By this I can access the count property (which is a must since the array itself does not change). The binding is based on key-value compliance which I established at the modell so the array can be accessed. But key-value compliance is not part of the questions. My question: How can I put the binding into the sourcecode and not writing it into the Interface Builder?
