  • Examples of different architecture methodologies

    - by Lane
    Is there a resource or site which illustrates building the same application (desktop or web) using several different contrasting architectures? Such as MVP versus MVVM versus MVC, etc. It would be very helpful to see how they look side-by-side using real-world code instead of comparing written theory to written theory. I've often found that something can be described well in a book, but when you go to implement it, the subtleties and weaknesses of the theory become readily apparent.

  • Ubuntu boot hangs after message "Running /scripts/init-bottom ... done"

    - by Douglas B. Staple
    I've been trying to copy a Proxmox container based on the Ubuntu Precise Standard template to a VirtualBox VM. I am now stuck at a point where my new Ubuntu/VirtualBox VM hangs after the message "Running /scripts/init-bottom ... done" during boot. I started by installing Ubuntu Server 12.04.4 LTS on a VirtualBox VM. Ubuntu Server 12.04.4 LTS was the closest "official" Ubuntu ISO to the Proxmox container OS I could find. I installed all updates on both the Proxmox container and on the VirtualBox VM. The idea was to get same version kernal running on the ProxMox container and VirtualBox VM. sudo apt-get update ; sudo apt-get upgrade ; sudo apt-get dist-upgrade sudo reboot rsync the entire proxmox container to a temporary directory in the VirtualBox VM: cd / mkdir /tmp/backup rsync -e ssh -av --exclude={/dev,/proc,/sys,/tmp,/run,/mnt,/media,/lost+found,/boot,/selinux} root@my_proxmox_container_hostname:/ /tmp/backup Shut down the virtual machine, and boot the VM with a bootable linux image. I used the Desktop image of Ubuntu 12.04 LTS, ubuntu-12.04.4-desktop-i386.iso Drop to a root prompt. Mount the VM root filesystem: sudo mount /dev/sda1 /mnt Remove files from most of /mnt cd /mnt sudo rm -rf bin etc home lib opt sbin root usr var Move all of the files from /mnt/backup into /mnt sudo mv /mnt/tmp/backup/* /mnt Rebooted system. For me, at this point the system freezes after starting, after the message: Running /scripts/init-bottom ... done I've tried reinstalling GRUB and all manner of other thing. I am almost ready to give up.

  • Can't Access TFS 2010 Beta 2 from Visual Studio 2010 Beta 2 when domain joined

    - by Brian Sullivan
    I'm experimenting with an installation of TFS 2010 Beta 2 on a virtual machine under VirtualBox running Windows Server 2008. When I've got the server in a workgroup, I can connect to it from Visual Studio just fine, as long as I provide credentials for a local user on the server machine when prompted by the "Connect to Team Foundation Server" dialog. The desktop I'm running Visual Studio on is joined to a domain. However, when I join the server to the domain, I can no longer connect to it from Visual Studio. I get a pretty generic error message: "TF31002 - Unable to connect to team foundation server". It gives me several different possible problems, including an incorrect address or an incorrect username and password. I've already added the domain Windows identity with which I'm logged on the the desktop to the TFS Admins group on the server, so I don't think it's a username/password problem. I've also tried putting the literal IP address of the server in the dialog address box instead of the machine name, but still no dice. I made sure that network discovery was enabled on the server, too, and can navigate to "\\webserver2008" in Windows Explorer without any problems. Shouldn't be a firewall problem, since the TFS install creates the appropriate exceptions in Windows Firewall. It's all a bit confusing, since it seems to work when the server is in a workgroup. Note: I'm a dev, not an admin, so there are many subtleties of server administration with which I'm not familiar. Please make no assumptions about what I may or may not have tried; what may be obvious to you may have never occurred to me. Thanks in advance!

  • untrusted (self-sign) certificate on android browser

    - by Basiclife
    Hi all, Apologies for the brevity of this question but due to an unfortunate series of events, I've managed to brick my PC so am posting from my phone... We've just set up Windows Small Business Server 2008 at work which has an external web portal accessible via HTTPS. We haven't yet bought?installed any certificates. The portal provides access to email, sharepoint, remote desktop, etc.... (I'm aware some of these are never going to work on the phone) From firefox / other desktop browsers, this displays an "untrusted cert' warning which I can choose to ignore. When browsing from my mobile I get a popup notification which says. "A secure connection could not be established" when I OK this (my only option) I see the standard android-generated "unable to load page - has it moved?" Page. Does anyone know of a way to either accept the certificate temporarily or allow untrusted certificates generally? I'm aware that the latter option is non-ideal in the mid to long term but at the moment, I need to access the portal and am willing to either toggle settings as/when required or forego using the mobile for banking, etc... to mitigate my risk. Thanks in advance for any help you can provide and apologies again for brevity In case it helps I'm on the G1 running android 1.6 using the default browser

  • XRDP errors when trying to use sesman-x11rdp

    - by Nicholas
    I've just installed Ubuntu 11.10 Desktop on an old laptop of mine and I wanted to set it up so I could remote into it from my windows desktop. I've installed XRDP, but when I attempt to login using sesman-x11rdp it logs in, then the window shuts down. I've checked over the logs and here is what I get at the time of login: [20120123-16:49:23] [INFO ] scp thread on sck 8 started successfully [20120123-16:49:23] [INFO ] granted TS access to user nicholas [20120123-16:49:24] [INFO ] starting X11rdp session...

  • VMWare Workstation 6.5.5 (64-bit) on Ubuntu 10.04 (64-bit) Odd Problem

    - by Android Eve
    I managed to successfully install VMWare Workstation 6.5.5 (64-bit) on Ubuntu 10.04 (64-bit). It works well and somehow feels faster and snappier than the same exact version on Ubuntu 8.04. However, there is one slight issue, somewhat hurting productivity: When the guest VM is Microsoft Windows (2K, XP), the mouse cursor turn from an arrow to a hand when it hovers over the Task Bar. When the mouse moves, this hand cursor blinks and the system doesn't respond to mouse clicks. When I move the mouse cursor back to the desktop area, it functions normally. That is, the problem exists only in the Task Bar area. Obviously, this makes it very difficult (read: impossible) for me to use the Start Menu, SysTray and the rest of the Task Bar. My workaround for now is to launch programs via their Desktop shortcuts or via the keyboard. Note: The same exact VMWare Workstation 6.5.5 (64-bit) on Ubuntu 8.04 (64-bit) doesn't exhibit this problem. Anyone seen this problem before? Do you know of a solution (or better workaround) to this problem?

  • Ubuntu12.04 crashed while trying to install Ubuntu14.04, no longer have access

    - by FACE
    Posting from my laptop, as my Compaq desktop crashed. Not very computer saavy, and not sure what info I should provide...but here's a start: 9 year old desktop Compaq SR 1650NX, AMD Athlon 3500+ probably 1 gB ram (duh....) Was running 12.04....was attempting to upgrade to 14.04, not sure if I interrupted it. Pretty much stuck on (constantly redirected to) a page which says "GNU Grub version 1.99-2"; it offers several choices (as written): Ubuntu, with Linux 3.2.0-67-generic Ubuntu, with Linux 3.2.0-67-generic (recovery mode) Previous Linux versions Memory Test (memtest86+) Memory Test (memtest86+, serial console 115200) But none of the selections seem to be able to get me anywhere (i.e., I click yes, but can't seem to run any commands - not that I know anything useful); I escape from those pages by repeatedly hitting CTRL-ALT-DEL Any help would be appreciated; will provide additional info when requested. Thanx (hopefully), in advance. (If I don't respond immediately, it just means I had to attend to other concerns...will leave page open and check back in as often as possible). FACE

  • Can't get my OpenVpn client to connect

    - by Larry
    Hi Guys, I am trying to setup a test vpn between my home desktop and my laptop. So far I have got the server on the desktop to connect fine but I can not get my laptop to finish the connection. I have tried several different configurations and they all give me the same result. Obviously it has nothing to do with my Client configuration but possibly something on my laptop? Here is the message I get in the log when it stops then times out and restarts.

  • Gnome-Applets Package Causing Gnome to Segfault

    - by FranticPedantic
    When I boot ubuntu I get a bunch of windows saying "The panel encountered a problem while loading: OAFIID:GNOME_ShowDesktopApplet", with a bunch of others(5) besides ShowDesktopApplet. I am able to launch a terminal, and I do have the taskbar at the top, although the bar at the bottom that holds the windows is blank, so when I minimize a window it disappears. Furthermore, when I try to launch most applications (firefox for example) it segfaults. I have googled the error but it seems to be common but general issue, and a lot of the solutions that worked for others didn't work for me. I tried deleting the gconf, gnome, and gnome2 folders in my home directory. I tried deleting a bunch of the gnome folders (although I might have done this wrong, I was confused as to which ones). I have also tried to use apt-get and dpkg to re-install ubuntu-desktop and gnome-applets. However, when I try apt-get install ubuntu-desktop I get errors regarding /var/cache/apt/archives/gnome-applets_2.28.0-0ubunt2_amd64.deb I tried dpkg --configure -a and interestingly I get Package gnome-applets is not installed. When I try to use apt-get to install it, that same pesky problem pops up error processing /var/cache/apt/archives/gnome-applets_2.28.0-0ubunt2_amd64.deb (--unpack) subprocess new post-removal script returned error exist status 245 sub process /usr/bin/dpkg returned an error code(1) This file has been popping up with regards to a lot of the solutions suggested I see. Any ideas?

  • Personal VPN Solutions

    - by dragonmantank
    I want to set up a VPN for my laptop to connect back at home so that I don't have to directly expose my desktop computer to the internet. Here is what I have: Internet -> DD-WRT v24sp1-mega -> Desktop PC w/ Windows 7 Ultimate -> MacBook w/ OSX 10.6 What would be the easiest thing to do? DD-WRT has PPTP and OpenVPN built in and Windows 7 has RRAS itself but thus far I've run into some problems. Are there any other alternatives, or suggestions on getting these to work? PPTP I tried setting up PPTP directly on DD-WRT using these directions. When I tried connecting using my external IP from the MacBook I just kept getting that the remote server did not respond. OpenVPN According to the instructions here I don't have enough open nvram to set up OpenVPN. RRAS I got RRAS set up without a problem and can connect from the MacBook to the Windows 7 box while I'm on the same network. I port forwarded 1723 on the DD-WRT back to the Windows 7 box and made sure that PPTP Passthrough was enabled. Again, like PPTP, it just kept timing out.
