  • Introducing Programming To a Mathematician

    - by ell
    I currently am a programmer, I'm almost 16 years of age and have pretty much narrowed my careers down to something involving a Computer Science degree or Electrical Engineering degree (I know they are quite different but this question is about my friend) but my friend isn't so sure. He is very interested in maths and is very good at it and I think he would enjoy programming but he isn't willing to try it (edit he is willing to try but has never done before). Can anyone give me an suggestions for a language or tool that he could dabble in programming (at a reasonably basic level I assume) to solve maths problems or involve some kind of maths. As I say he enjoys maths a lot but I think he would enjoy programming, the problem is I don't want him to be put off by the stuff that isn't relevant at introductory levels such as memory allocation et al. I know that is very important but the point is that I want him to learn a bit of programming with maths then hopefully if he is interested enough he can start learning programming as programming. Thanks in advance, ell. Edit: Its not that he's completely uninterested - more that he hasn't actively explored the area before, maybe because he isn't informed about it. I wouldn't want to force him to do something he doesn't want to, I see this as more of a little push so that he can learn about programming. If he doesn't like it - fair enough, I can't control that and don't want to but if he turns out to enjoy it - this push will have been the right thing.

  • Why do I have a gnomekeyring.IOError when doing "quickly share"?

    - by Agmenor
    When I want to push my app to Launchpad by doing quickly share --verbose, I get the following Gnome Keyring error: Get Launchpad Settings Traceback (most recent call last): File "/usr/share/quickly/templates/ubuntu-application/share.py", line 101, in <module> launchpad = launchpadaccess.initialize_lpi() File "/usr/lib/python2.7/dist-packages/quickly/launchpadaccess.py", line 91, in initialize_lpi allow_access_levels=["WRITE_PRIVATE"]) File "/usr/lib/python2.7/dist-packages/launchpadlib/launchpad.py", line 539, in login_with credential_save_failed, version) File "/usr/lib/python2.7/dist-packages/launchpadlib/launchpad.py", line 342, in _authorize_token_and_login authorization_engine.unique_consumer_id) File "/usr/lib/python2.7/dist-packages/launchpadlib/credentials.py", line 282, in load return self.do_load(unique_key) File "/usr/lib/python2.7/dist-packages/launchpadlib/credentials.py", line 336, in do_load 'launchpadlib', unique_key) File "/usr/lib/python2.7/dist-packages/keyring/core.py", line 34, in get_password return _keyring_backend.get_password(service_name, username) File "/usr/lib/python2.7/dist-packages/keyring/backend.py", line 154, in get_password items = gnomekeyring.find_network_password_sync(username, service) gnomekeyring.IOError ERROR: share command failed Aborting This used to work, so this means that I already have SSH and GPG configured. This is probably part of the explanation: I have this error when I am connected to this machine through a ssh tunnel with X forwarding. But I don't have it when I have physical access to the computer. Could you please give me some indications on what to do?

  • Simple Workstation Imaging Solution?

    - by Will
    Hey guys, I need a fairly cheap imaging solution for Windows XP corporate desktops. Ideally, I'd be able to set up a desktop exactly as we want it, create an image, deploy this image to a server, then boot a new desktop to a CD/USB Drive/Network and quickly set up the workstation. Ideally, each computer would also have a unique workstation name. Any ideas? Right now I'm using a custom built Linux DD solution, but it's slow, not network-based, can't image multiple computers at the same time as there's only one copy on a USB drive, and can't uniquely name the computers. Thanks, Will

  • Screen Resolution stuck at 640x480 after installing Bumblebee

    - by Saurabh Agarwal
    I have a Dell XPS 15z laptop. As you can see here, there are some issues with NVidia drivers. The site recommends installation of Bumblebee (instructions given in the link). I am posting it again for ease: $ sudo add-apt-repository ppa:bumblebee/stable $ sudo apt-get update && sudo apt-get upgrade $ sudo apt-get install bumblebee bumblebee-nvidia $ sudo usermod -a -G bumblebee $USER After restarting the computer however, the screen resolution was stuck at 640x480 and I got the following error message as soon as I logged in: **Could not apply the stored configuration for monitors** none of the selected modes were compatible with the possible modes: Trying modes for CRTC 63 CRTC 63: trying mode 640x480@60Hz with output at 1366x768@60Hz (pass 0) CRTC 63: trying mode 640x480@60Hz with output at 1366x768@60Hz (pass 1) Trying modes for CRTC 64 CRTC 64: trying mode 640x480@60Hz with output at 1366x768@60Hz (pass 0) CRTC 64: trying mode 640x480@60Hz with output at 1366x768@60Hz (pass 1) Prior to the update, the display was absolutely normal and thus there is no doubt about the cause. Albeit, there was no support for graphic drivers. In case it helps, some features of graphics drivers seem to be functional after bumblebee, ie, all features are in order except for the resolution. And if the resolution can't be fixed, please suggest a way to retract the changes so that atleast the prior state may be reachieved. Any help in the matter would be highly appreciated.

  • I need something substantial to do [on hold]

    - by Christian Delapena
    I'm a 19 year old computer geek who was recently exposed to Linux. I know quite a bit of it now and would like to do something substantial with it. I've visited websites like openhatch where you can get started on opensource projects but I'm more interested in something Linux-specific like hosting a website or tracking some important operation. Maybe running a script that will give me data on something important. I don't know. I'm essentially bored and I want to put my knowledge and love of Linux to good use. Someone please point me in the right direction.

  • Universal Windows XP With Ghost and Sysprep

    - by RobertPitt
    Hey I have an idea but im not sure whether it is possible and looking for advice on how to accomplish this. If i was to try and deploy Windows XP Sysprepped image from a Lenovo Thinkcentre 6073-CTO and tried to drop it onto a Dell Optiplex for instance I would get a BSOD due to the hardware change. What im looking to do is create a few images like so: Windows XP x86 SP3 (Sysprepped) Windows XP x64 SP3 (Sysprepped) ... So that we can use throughout the organization without having to create individual images per computer type. Is there anyway's to accomplish this such as some modification of files pre-ghost, removal a certain drivers pre-sysprep Any advice is appreciated.

  • Can admins monitor my activity locally even when I use a VPN?

    - by Arjun Create
    My school has one of those super overreacting web blockers (specifically Fortisnet) that blocks things that should be accessible by a high-school senior trying to research projects. Despite many students' complaints the administration's hands are tied due to parents' complaints. I have setup a VPN account from http://www.vpnreactor.com. With this I am able to bypass the blocker. I know this service hides my IP from websites and servers on the web. I also know that the school pays an IT guy just to monitor sites and network traffic that the students are using. Basically, will he be able to see my network traffic? More importantly, will he be able to trace it to my computer or its MAC address? I am connecting over Wi-Fi, not ethernet.

  • Can't install Ubuntu on my Windows 7 laptop

    - by Ana
    I tried installing Ubuntu in two different ways: First, I tried the Windows Installer, and it goes well until I reboot the system and, when booting on Ubuntu, I get the error: No root file system defined. Second, I uninstalled wubi by going to to Control Panel - Uninstall Programs - Ubuntu. Then, I booted the laptop from the live CD and selected install. It boots okay but in the screen right after the one that says to make sure you have 4.5 GB available, Internet connection, etc, when I click continue it throws me a message saying that Ubuntu had an internal error and asks me if I want to report the error. After that, I just have a black screen and nothing else! No Ubuntu installed, no boot option to go back to Windows. Nothing! My goal is to install Ubuntu alongside Windows 7 (without the hassle of formatting the computer, creating partition, etc). How can I do it (preferable using Windows Installer)? How can I solve the "No root file system defined" that I encountered when I used the Windows Installer?

  • Accidentally replaced the partition table using GParted in UBUNTU

    - by claws
    Hello, This machine has UBUNTU & wINDOWS XP. I'm currently logged into UBUNTU. I was just checking the features of GParted and accidentally clicked Device > Create Partition Table. A default MS-DOS partition table is created. Now if I re-start the Gparted there is nothing. Its showing entire disk as UNALLOCATED space. Lucky thing is All the drives (C:, D:, E:) are currently mounted and I'm in UBUNTU. I guess its possible to re-create the partition table using current status. But I don't know how? Can any one kindly tell me how to do this. This is a lab computer. If its not recoverable. I'm completely screwed!!

  • Why do browsers have so many possible exploits?

    - by Beau Martínez
    When browsing I am ocassionally given warnings about pages that host malware "that could damage my computer". I am seriously perplexed as to why, in 2010, browsers still have possible exploits and can be cracked. My question is "Why?". I'm assuming it's because of the quick development that occured in the browser wars which were unsufficiently tested, but I'm unsure. Surely WebKit would have patched all the issues in KHTML, or Gecko sorted out the flaws in Netscape's engine, and the IE coders sorted through their codebase to eliminate possible flaws? (Somewhat related: http://superuser.com/questions/117770/which-browser-is-the-most-secure-research-and-practically-based.)

  • Driver choice for addressing ubuntu wireless card issues

    - by Holly
    Hello, this should be a relatively simple question. I'm attempting to get my windows wireless card to work with ubuntu, booted from my portable hard drive. This is the guide I'm attempting to follow is on help.ubuntu.com, /community/WifiDocs/Driver/Ndiswrapper My wireless card is a Broadcom Corporation BCM4318 AirForce One 54g 802.11g Wireless LAN Controller. My computer is an HP Pavilion Entertainment dv5 notebook, which came with Vista 64. I would like confirmation about which of the drivers I should use. At this point, I'm leaning towards Broadcom BCM4318 HP Pavilion zv6000, but I thought it best to ask advice before taking action. The drivers I have to chose from are listed on this page http://sourceforge.net/apps/mediawiki/ndiswrapper/index.php?title=Category:Broadcom Thanks! Holly

  • Unable to play bluray movies or see bluray discs

    - by Jason Shultz
    I have a Optiarc BD ROM BC-5500S ATA Device and when I put bluray discs into the drive the computer doesn't read them. I hear the drive make 3 noises as if it's trying to read them. Nothing shows up in windows explorer. I am running windows 7 64bit. I can read DVDs and CDs just fine. Bluray seems to be the only problem. I have installed PowerDVD9, HP DVD Play and HP DVD Media Smart and nothing helps. My laptop is a hp dv7 1273cl. I bought it before the free upgrades to windows 7 were available so I wasn't able to get the upgrade and so HP won't assist me beyond telling me to format and reinstall Vista.

  • Using AHK PostMessage to send WM_WININICHANGE to Program Manager

    - by SaintWacko
    I've written a script which updates an environment variable, but I need to tell Program Manager to update the computer's programs with this new information. I was given this as the API call that is made within another program to cause this: ::SendMessage(::FindWindow("Progman", NULL), WM_WININICHANGE, 0L, (LPARAM)"Environment"); I am attempting to translate this into an AutoHotKey PostMessage call, but I'm doing something wrong, as it isn't working. Here's where I've gotten so far: PostMessage, 0x1A,, (LPARAM)"Environment", "Program Manager" Here are the AHK resources I've been looking at to do this: List of Windows Messages Send Messages to a Window or Its Controls PostMessage / SendMessage And here are the resources that I used to figure out the original API call: SendMessage function WM_WININICHANGE message Can anyone help me figure out what I'm doing wrong?

  • Is there an easy way to read blu-rays on Windows?

    - by ereOn
    Some time ago, I bought my parents a computer dedicated to medias (mostly photographs and movies trough DLNA). My father asked me if he could read blu-ray on it, so I bought a blu-ray reader but I can't find a software to do the playback. I installed PowerDVD (a free version we got with a Blu-Ray) but it seems it now requires a (non-free) upgrade. Even if it were free, I hardly see my parent do the upgrade by themselves as they barely understand how computers work. I thought I would find a free software (something like VLC, but for blu-rays) but so far had no luck. Do you guys have a software to suggest that would solve my issues ? It should run on Windows Vista, shouldn't require an update every monday, or at least a free one. Thank you very much.

  • With which class to start Test Driven Development of card game application? And what would be the next 5 to 7 tests?

    - by Maxis
    I have started to write card game applications. Some model classes: CardSuit, CardValue, Card Deck, IDeckCreator, RegularDeckCreator, DoubleDeckCreator Board Hand and some game classes: Turn, TurnHandler IPlayer, ComputerPlayer, HumanPlayer IAttackStrategy, SimpleAttachStrategy, IDefenceStrategy, SimpleDefenceStrategy GameData, Game are already written. My idea is to create engine, where two computer players could play game and then later I could add UI part. Already for some time I'm reading about Test Driven Development (TDD) and I have idea to start writing application from scratch, as currently I have tendency to write not needed code, which seems usable in future. Also code doesn't have any tests and it is hard to add them now. Seems that TDD could improve all these issue - minimum of needed code, good test coverage and also could help to come to right application design. But I have one issue - I can't decide from where to start TDD? Should I start from bottom - Card related classes or somewhere on top - Game, TurnHandler, ... ? With which class you would start? And what would be the next 5 to 7 tests? (use the card game you know the best) I would like to start TDD with your help and then continue on my own!

  • Install Nod32 antivirus silently?

    - by IT Tech
    Hi guys/gals, I was hoping that I could find someone on here that may know if it is possible to install Nod32 on a client PC silently. We have some software that will copy the MSI to the remote PC and run it with any specified parameters. The software needs you to import the license key file and tell it where the server is. Is there any way that these details can be pre specified so the user doesn't have to have any interaction on the remote computer. Many thanks in advance.

  • How to Track Duplicate Downloads

    - by user1089173
    I have a product and we are running a campaign for it to allow users to download a trial version. My questions is there any way to detect multiple downloads from the same computer but behind a proxy. For example if a person uses a proxy server, changes his/her ip and downloads our trial version multiple times from different Ip's, is there a way to detect that it is the same person who's downloading the s/w. We use only Name and Email addresses to be entered before downloading our s/w and that can easily be created. We cannot add any other fields to the form (like phoneno.)

  • New apache on mac

    - by Keith
    I have installed php5 apache2 mysql5 and postgresql84 using MacPorts. I realize my mac already has apache but it didn't have apache2 nor postgesql hooked up to use with php. I want to not use the default apple apache and use the new macports install. How do I tell my computer to stop looking at the old apache? When I do apachectl in the terminal I believe it is using the old apache. I would like to hook it up to use the new one. How would I do that? The new stuff is installed at /opt/local/apache2 and the old stuff is installed at /private/etc/apache2 I went to system preferences...Sharing...and shut off Web Sharing but when I do apachectl's that turns it on and off in the preferences. I'm running in Snow Leopard.

  • Can't ping some IP addresses in the same subnet (LAN) Windows 2011 Server

    - by Ricardo
    Hi I’m running in Windows Small Server 2011 server standard (192.168.1.108), it’s my dhcp and dns server too, but suddenly all other users can’t get internet. My gateway is 192.168.1.1. After a lots of tested I can saw that my server can’t get into the router (192.168.1.1), and also into some others computers, but some other computers answer the ping command. In fact the same computer with the IP 192.168.1.9 didn't answer, but with the IP 192.168.1.63, it response! I have no routers, firewall, vlans or anything that disallow the traffic between computers, in fact when I changed the server IP address (192.168.1.109), I be able to ping the other computers and gateway, but if a back to the 192.168.1.108 the trouble comeback. I hope you can help me with this issue Ricardo

  • Wireless not working on desktop with Asus USB-N13 (B1) wireless adapter

    - by user900749
    I am trying to connect my desktop to a wireless network. I have purchased an ASUS USB-N13 B1 adapter. I have followed instructions for installing drivers and disabling conflicting drivers. I have thoroughly searched and could not find a solution. The adapter is recognized and powered on. I have entered the ssid and password information into the wireless network configuration. Other machines can connect to this wireless network, and the machine can connect online via ethernet without issue. Here is the output of some commands which summarize my configuration, and might give some clues : ~$ cat /etc/lsb-release DISTRIB_ID=Ubuntu DISTRIB_RELEASE=12.04 DISTRIB_CODENAME=precise DISTRIB_DESCRIPTION="Ubuntu 12.04.1 LTS" ~$ uname -a Linux petra 3.2.0-29-generic #46-Ubuntu SMP Fri Jul 27 17:03:23 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux ~$ lsusb Bus 001 Device 006: ID 0b05:17ab ASUSTek Computer, Inc. ~$ dmesg [ 1883.823150] wlan0: authenticate with 48:5b:39:e7:25:5e (try 1) [ 1884.020027] wlan0: authenticate with 48:5b:39:e7:25:5e (try 2) [ 1884.220025] wlan0: authenticate with 48:5b:39:e7:25:5e (try 3) [ 1884.420023] wlan0: authentication with 48:5b:39:e7:25:5e timed out Any assistance would be appreciated as I have been trying to get this machine online for several weeks now to no avail.

  • Firefox's master password does not protect my web accounts

    - by Mehper C. Palavuzlar
    I've set up a master password in Firefox 3.6 but it's not working as I expected. I always save my passwords within Firefox for frequently visited sites like Facebook, Yahoo! mail, Gmail, Twitter etc. and this way I don't have to type in my password every time I open that site. When I open Firefox, it asks for the master password but when I click Cancel, it opens normally, and lets me directly in my Facebook page, or Yahoo! Mail page. Why doesn't it protect my accounts? This way, anyone using my computer can see my accounts and it's totally pointless for me to use this master password. How can I protect my accounts with saved passwords in Firefox?

  • Android tethering question

    - by Solignis
    Hi there, I have a Motorola Droid 1 with Android 2.2 on it. I found something odd that I don't understand why it works. If I plug my phone into my home computer which is Windows 7 and I turn on the tethering ability, I am met with a Verizon captive portal and it tells me I need to pay for a tethering plan (which I don't have). Now the weird thing, if I plug the same phone into my Ubuntu 10.10 laptop and enable tethering it works and can get on the internet with no captive portal showing up. The only thing I could notice that was different about the connections was Windows connected to the phone with an NDIS driver and Linux connected to the phone with what I think is a raw device mapping. Would that have anything to do with it?

  • Google Glasses–A new world in front of your eyes

    - by Gopinath
    Google is getting into a whole new business that would help us to see the world in a new dimension and free us from all gadgets we carry we today. Google Glasses is a wearable tiny computer that brings information in front of your eyes and lets you interact with it using voice commands. It’s a kind of glasses(spectacles) that you can wear to see and interact with the world in a new way.  With Google Glasses, for example you can look at a beautiful location and through voice you can instruct it to capture a photograph and share it to your friends. You don’t need a camera to capture the beautiful scene, you don’t need an App to upload and share it.  All you need is just Google Glasses By the way these glasses are not heavy head mountable stuff, they are very tiny one and look beautiful too. Check out the embedded video demo released by Google to see them in action and for sure you are going to be amazed.   Last year December 9 to 5 Google posted details about this secret project and NY Times says that these glasses would be available to everyone at affordable cost, anywhere between $250 and $600. It is powered by Android OS and the contains a GPS, motion sensor, camera, voice input & output devices. Check out Project Glass for more details.

  • Can web apps allow fast data-typists to "type-ahead"?

    - by user61852
    In some data entry contexts, I've seen data typists, type really fast and know so well the app they use, and have a mechanic quality in their work so that they can "type ahead", ie continue typing and "tab-bing" and "enter-ing" faster than the display updates, so that in many occasions they are typing in the data for the next form before it draws itself. Then when this next entry form appears, their keystrokes fill the text boxes and they continue typing, selecting etc. In contexts like this, this speed is desirable, since this persons are really productive. I think this "type ahead of time" is only possible in desktop apps, but I may be wrong. My question is whether this way of handling the keyboard buffer (which in desktop apps require no extra programming) is achievable in web apps, or is this impossible because of the way web apps work, handle sessions, etc (network latency and the overhead of generating new web pages ) ? Edit: By "type ahead" I mean "keyboard type ahead" (typing faster than the next entry form can load), not suggets-as-you-type-like-google type ahead. Typeahead is a feature of computers and software (and some typewriters) that enables users to continue typing regardless of program or computer operation—the user may type in whatever speed he or she desires, and if the receiving software is busy at the time it will be called to handle this later. Often this means that keystrokes entered will not be displayed on the screen immediately. This programming technique for handling user what is known as a keyboard buffer.
