• How to repackage NVIDIA .run drivers into .deb with DKMS

  - by Delan Azabani

  At present, Ubuntu offers the 195.36.24 drivers as nvidia-current in their repository. This packaged driver is pretty cool as it uses DKMS so you don't have to keep reinstalling the driver after a new kernel version. The NVIDIA .run package drivers are at version 257 (beta) but they don't use DKMS so the graphics screws up every time a new kernel is installed and you don't reinstall the driver. How can I modify the .run to use DKMS and even better, package it as a deb package?

• Prevent checkins to SVN

  - by Joseph Mastey

  My team uses SVN for our software platform, and we create tags periodically to help keep module versions straight. Best practice, as I understand it, is not to modify a tag once it has been created. However, it seems that sometimes the temptation is too great and a modification is made to one of the tags. Is there a way to prevent these kinds of checkins, or at least make them a complete pain so that we can discourage them automatically? Thanks, Joe

• C syntax or binary optimized syntax?

• cannot open file cua in second instance of emacs

  - by Toddeman

  i get the following error when trying to open a second instance of emacs: File error: "Cannot open load file" , "cua" I guess I don't HAVE to open another instance of emacs (that is the beauty after all), I was just trying to keep some things separated (specifically work - like code and debug - and play - like news). Would there be any reason I could not open two instances of emacs if I use cua.el?

• Android: How to prevent image from being scaled in ImageView or ImageButton?

  - by user277827

  Hi, How can I prevent my bitmap from being scaled automatically in an ImageView or ImageButton if the view or button is stretched using "fill_parent" or using "weight"? This will be useful, for example, to create a 4-button toolbar at the top of the screen where the buttons are equally spaced, but the images inside the buttons keep getting streched even if I use scaleType="center", which should prevent scaling according to the doc, but it doesn't. Any insight is appreciated! Thanks,

• How to treat a symbolic link as a directory in Mercurial?

  - by celil

  As of 0.9.4, when adding a symbolic link Mercurial keeps track of the link itself, and not the file or directories it points to. However, there are cases when it is desirable to keep track of the files pointed to by the symbolic link. How can I force Mercurial to treat the symbolic link to a directory as a regular directory?

• Problems related to showing MessageBox from non-GUI threads

  - by Hans Løken

  I'm working on a heavily data-bound Win.Forms application where I've found some strange behavior. The app has separate I/O threads receiving updates through asynchronous web-requests which it then sends to the main/GUI thread for processing and updating of application-wide data-stores (which in turn may be data-bound to various GUI-elements, etc.). The server at the other end of the web-requests requires periodic requests or the session times out. I've gone through several attempted solutions of dealing with thread-issues etc. and I've observed the following behavior: If I use Control.Invoke for sending updates from I/O-thread(s) to main-thread and this update causes a MessageBox to be shown the main form's message pump stops until the user clicks the ok-button. This also blocks the I/O-thread from continuing eventually leading to timeouts on the server. If I use Control.BeginInvoke for sending updates from I/O-thread(s) to main-thread the main form's message pump does not stop, but if the processing of an update leads to a messagebox being shown, the processing of the rest of that update is halted until the user clicks ok. Since the I/O-threads keep running and the message pump keeps processing messages several BeginInvoke's for updates may be called before the one with the message box is finished. This leads to out-of-sequence updates which is unacceptable. I/O-threads add updates to a blocking queue (very similar to http://stackoverflow.com/questions/530211/creating-a-blocking-queuet-in-net/530228#530228). GUI-thread uses a Forms.Timer that periodically applies all updates in the blocking queue. This solution solves both the problem of blocking I/O threads and sequentiality of updates i.e. next update will be never be started until previous is finished. However, there is a small performance cost as well as introducing a latency in showing updates that is unacceptable in the long run. I would like update-processing in the main-thread to be event-driven rather than polling. So to my question. How should I do this to: avoid blocking the I/O-threads guarantee that updates are finished in-sequence keep the main message pump running while showing a message box as a result of an update.
