  • NVIDIA GFORCE 610M drivers

    - by thefinn93
    I'm attempting to install drivers for my GFORCE 610M and none of the solutions seems to work. Generally people recommend using the jockey-gtk program, which doesn't detect the card and states that there's no propitiatory drivers to install. I tried download the official binary from the NVIDIA site, but that told me that I had to remove the Nouveau kernal driver, so I did that, following the instructions on the wiki (apt-get remove --purge xorg-something or other) and ignoring the "DON'T DO THIS" warning, after that didn't do anything i installed various packages (nvidia-common, nvidia-settings, etc) and eventually got the nvidia-settings program (and a very low screen resolution). Unfortunately when I open nvidia-settings it tells me to run nvidia-xconfig as root (i've done this several times, but to no avail) and doesn't let me configure anything. At this point I tried re-running the binary installer i downloaded from nvidia's site, and it said it worked but it didn't change a thing. So I'm out of ideas, what've you got?

  • Gradient boosting predictions in low-latency production environments?

    - by lockedoff
    Can anyone recommend a strategy for making predictions using a gradient boosting model in the <10-15ms range (the faster the better)? I have been using R's gbm package, but the first prediction takes ~50ms (subsequent vectorized predictions average to 1ms, so there appears to be overhead, perhaps in the call to the C++ library). As a guideline, there will be ~10-50 inputs and ~50-500 trees. The task is classification and I need access to predicted probabilities. I know there are a lot of libraries out there, but I've had little luck finding information even on rough prediction times for them. The training will happen offline, so only predictions need to be fast -- also, predictions may come from a piece of code / library that is completely separate from whatever does the training (as long as there is a common format for representing the trees).

  • How would you find the height of objects given an image?

    - by Ram Bhat
    Heyguys.. This isn't exactly a programming question exactly. I just want to know what your approach would be to a common problem in Digital image processing. Lets say you have an image of a a few trees in say jpg format. How would you go about finding the heights of each of these trees. The photo is the only input you have. I want to know the approaches you have not code. So it doesnt matter if your answers are vague, or non DIP-ish.

  • What is a byte stream actually?

    - by user2720323
    Can anyone explain me what byte stream actually contains? Does it contain bytes (hex data) or binary data or english letters only? I am also confused about the term Raw Data. If someone asked me to "reverse the 4 byte data", then what should I assume the data is hex code or binary code? Can anyone please clarify this for me. I have read so many articles and in java and c. They used to talk these words frequently but never understood them clearly.

  • How to use cyg-wrapper to fork a new tab in win32 gvim

    - by Peter Nore
    I would like to set up an alias in my cygwin .bashrc that translates pathnames unix-to-dos and passes them to windows gvim in a new tab of an existing instance. I am trying to use Luc Hermitte's cyg-wrapper script for running native win32 applications from Cygwin as per this vim tip. Luc's example of how to use his script is: alias vi= 'cyg-wrapper.sh "C:/Progra~1/Edition/vim/vim63/gvim.exe" --binary-opt=-c,--cmd,-T,-t,--servername,--remote-send,--remote-expr' I do not understand this example because most of these vim parameters (-c,--cmd,--servername,--remote-send,--remote-expr, etc) require more information, and I have not found any example of how to supply the additional information to cyg-wrapper.sh. For example, calling C:/Progra~1/Edition/vim/vim63/gvim.exe --servername=GVIM --remote-tab-silent file1 & will open file1 in a new tab of existing (or non existing) instance GVIM, but calling gvim --servername accomplishes nothing on its own. Unfortunately, though, the corresponding cyg-wrapper phrase does not work: cyg-wrapper.sh "C:/Progra~1/Edition/vim/vim63/gvim.exe" --binary-opt=--servername=GVIM,--remote-tab-silent --fork=2 file1 If ran twice, this actually opens up two instances of gvim; it is as if the servername 'GVIM' is being stripped and ignored. How do you supply a servername to gvim --servername or a .vimrc to gvim -u using cyg-wrapper.sh? Furthermore, why is it that programs must be passed to cyg-wrapper.sh in the relatively obscure "mixed form?" For example, if I try cyg-wrapper.sh "/cygdrive/c/path/to/GVimPortable.exe" --binary-opt=--servername=GVIM,--remote-tab-silent --fork=2 I get "Invalid switch - "/cygdrive"."

  • Apt pin and self hosted apt repo

    - by Hamish Downer
    We have our own apt/deb repository with a handful of packages where we want to control the version. Crucially this includes puppet, which can be sensitive to versions being different. I want our desktops to only get puppet from our repository, but also for people to be able to add their own PPAs, enable backports etc. The current problem we have is backports on Ubuntu Lucid.

  • How can I find files added to the system within X minutes of a specific time?

    - by Jack W-H
    I have done a fresh install of Mac OS X Mountain Lion today on a new MacBook. Because this was a new install, when I finally got round to configuring some of my own developer things, I was surprised to find some app had installed a binary into /usr/local/bin - a single binary called galileod. Interestingly, I can't find anything online about galileod. I had only installed the bare minimum of software at this point. Looking in the file columns I can see Date Modified was 9th November 2012, but Date Added to the system was today at 17:01. It's now 10:20PM and I can't remember which software I was installing at that point. So how do I find out which other files were installed to the system within, say, 5 minutes either side of 17:01? EDIT: I found out what galileod was by running galileod --help - it is a binary used with Fitbit to communicate with the USB dongle. So that's the mystery solved - but it would still be interesting to know how to find files added within X minutes of a timeframe for future reference.

  • Logging Remote Server Access via Remote Desktop

    - by Nate Bross
    The objective here is to start a simple .NET application I've written which captures some environment variables (time, username, computername, etc) upon login. This .NET application subscribes to the Windows "User logout" event. Upon launch, the application captures the above variables, and creates a record in my database, upon logout (which I'm capturing) I update another field in the same record, with the logout time. The above is working exactly as I would like, when I launch the binary, it makes its initial log entry, then waits for the logout event and updates the same record. Restrictions, the .NET binary should be able to live on a share point (\server\share\myapp\v1) so I can update the application to (\server\share\myapp\v2) and simply update the GPO/Logon script. My initial thought was to use the \domaincontroller\sysvol\ directory to store the binary and then update all user accounts to include a call to my application. Can you see any flaws in this approach? My question is this: First, is there anything wrong with my idea above? Second, if so, what is the best way (through group policy or otherwise) to ensure this application launches whenever a session is started on a server?

  • Euro character messed up during FTP transfer

    - by djechelon
    My customer is using a very outdated ecommerce management system on my hosting service. For that product, no support is being provided anymore by the vendor. Brief explanation: the shop website, that claims to run under LAMP stack, is built by an old Visual Basic Windows application running on MS Access. The user constructs the shop, defines the HTML template, adds products and categories, etc. Then the VB exe builds the PHP pages (one for each template page) and the SQL script to run on MySQL. It also uploads everything via FTP and runs the installation/upgrade script on its own. The problem Browsing the website, many products' descriptions are cut before the euro sign. For example, what was supposed to be "Product price €1000" becomes "Product price" The analysis MySQL contains a cutted description until the € sign, so it's not PHP fault The Access databases contain full description with € sign, so it's not fault of the webmaster writing bad description or eDisplay cutting them The SQL that will run once the site gets uploaded, stored on my local machine before upload, contains the € sign The same script, after being FTPed by eDisplay and opened with nano from SSH, shows the € sign messed up like this: ^À vsftpd log reports (obfuscated for privacy) Sat Dec 15 11:16:57 2012 22 xxx.xxx.128.13 1112727 /srv/www/domains/xxxxxx.it/htdocs/db.sql b _ i r xxxxxxx ftp 0 * c which seems to be a binary transfer (and also a huge security vulnerability because you can download the whole database from unauthenticated HTTP) The eDisplay internal FTP client provides no option for ascii/binary transfer modes [Add] Trying to manually upload the SQL file via SFTP shows messing up euro [Add2] Trying to manually upload using Xftp client with explicit ASCII mode doesn't fix too It looks like the file gets uploaded as binary. Perhaps on the customer's previous host it all worked fine because that was a Windows host. The server It's an Azure virtual machine running openSUSE 12.2 with both vsftpd and openSSH The question Without asking the customer to manually upload files using FileZilla or replacing € with &euro;, because he refuses, what can I do on server side to prevent vsftpd to screw up euro sign?

  • How to merge Windows registry hives directly without converting them to an intermediate text based file?

    - by Registrar
    Help! I'm going to get fired if I can't figure out how to do this by tomorrow. Microsoft Windows stores its registry databases (known as "registry hives" - there's actually a backstory to the origin of this name, but I digress) in a proprietary binary format. Answer this correctly or you lose your job: Let H-sub-A be the registry hive of Computer A, and let H-sub-B be the registry hive of Computer B. Create a registry hive H-sub-A-prime (in the native binary format) that contains all of the registry keys and values in both H-sub-A and H-sub-B. If there is overlap, let the value from H-sub-B overwrite the value in H-sub-A. Sure, you can import a text-based patch file (e.g., "FOO.REG") to modify the registry, but can you merge two registry hives in their native binary format? Answers that involve exporting the registry to a text file (e.g., "FOO.REG") will receive no credit. You may only use software included with Microsoft Windows (any version) and / or third-party tools that are free of charge.

  • Interpolating height on opengl quad

    - by ThePlague
    Okay I've got a quad, see picture. And want to find the height at any point in the quad, is there a way to do this accurately as bilinear interpolation doesn't work in this case. As you can see the trees trunk is well beneath the terrain and should be at the same height as the trunks around it. I know the altitude of the vertices marked by a red circle and the centre red circle is roughly where the base should be, I've also crudely added a line as that surface is not flat.

  • Shadow Mapping and Transparent Quads

    - by CiscoIPPhone
    Shadow mapping uses the depth buffer to calculate where shadows should be drawn. My problem is that I'd like some semi transparent textured quads to cast shadows - for example billboarded trees. As the depth value will be set across all of the quad and not just the visible parts it will cast a quad shadow, which is not what I want. How can I make my transparent quads cast correct shadows using shadow mapping?
