  • Problem with Nvidia after update

    - by user214673
    After adding the most recent set of updates, I can't get into Ubuntu at all. I get a screen saying that I am running in low-graphics mode, 'your screen, graphics card and input device settings could not be detected correctly etc'. I can hit return and then get to the next screen saying 'what would you like to do?' however, i can't choose from the 4 options, the only keystroke that will register is escape, which takes me to a black screen with a login. I have an Nvidia GeForce 7050/nForce 610i and it has caused problems in the past, but I have always got round it by choosing to boot in recovery mode. Now, no matter which version I try to boot into I can't get into Ubuntu at all.

  • How to Create a Powerful Website That Sells Today?

    If you are trying to make money online, you simply must have a well designed website. When it comes to designing their websites, many internet marketers think very short term and do a low quality rush job. Putting up a cheap or cookie cutter type website will not bring you the online success that you desire. Whatever time it takes to make an attractive website that is appealing to visitors should be considered a necessary investment in your future success. Some people think it's very hard or that you have to be some kind of technical genius to make a good website; thankfully, this isn't the case.

  • How many LOC/day "top" (google, MS, FB) engeneers produce? [closed]

    - by NoSenseEtAl
    I know that 25 lines of lock free code is harder to do than 1000 lines of On_Click()... code but I wonder does anybody know in general what is the productivity of the average programmer in top tech companies. Motivation: I often go ??? mode when I see how low LoC/ day i produce(Im new to the my current language and Im part of the big project, but still..) and I would like to know how bad I am. :) If you are gonna warn me that LoC is a terrible measure I agree, but it is most exact one in a sense that I cant go and write 0.01% of Chrome or IE and say it took me this long so....

  • 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?

    - by user70113
    Currently Work in IT support and am retraining in electrical engineering / electronics, I am also interested in Reverse Engineering which language would be best for Hardware RE, I have seen a few sources say C, C++ and Python? I am not familiar with Linux, but installed ubuntu to learn with. I am not a programmer far from it, but I can understand enough basic VB,Java and PHP to edit it for simple things. One of my immediate projects would be to learn to reverse engineer USB devices and write my own low level drivers, I know there are porting kits, but I really want to know it from the ground up. Thanks for any advise folks Most Appreciated.

  • Looking for a previous post about skillsets for an embedded/firmware engineer. Can't find it anymore [closed]

    - by Sandiego
    I remember reading a post inquiring the basic/advanced skills required for embedded engineer works. The top comment divides the answer into two parts, the basic level/design level ,not purely coding(something like this...). Then another level : writing application(all about programming). For each level/category, the top comment talks about the necessary skills/knowledge/college courses(for me at least) . While I was searching for this post as I was trying to read it again, I found similar questions, but these are not the one I saw: http://stackoverflow.com/questions/1091931/what-skill-set-should-a-low-level-programmer-possess http://stackoverflow.com/questions/45247/how-do-i-get-started-in-embedded-programming http://electronics.stackexchange.com/questions/3343/how-to-become-an-embedded-software-developer Has anyone seen the post I'm talking about? This is a repost from Stackoverflow where I was told that this question is off-topic. So..please help guys

  • Which countries have suitable laws for game development companies? [on hold]

    - by yoni0505
    Which countries are most suitable for game companies? By suitable I mean: Their laws let the business be more profitable. (for example: low taxes) Have less bureaucracy. (for example: creating a company, employment laws) Living there isn't expensive. (for example: rent and food prices) etc... In short - maximum revenue with minimum overhead. What other things do I have to consider when choosing the place to be in? Are there any articles about this subject? (I couldn't find any)

  • GDI handles in a DotNET application

    - by David Rutten
    My pure DotNET library runs as a plugin inside an unmanaged desktop application. I've been getting a steady (though low) stream of crash reports that seem to indicate a problem with GDI handles (fonts in error messages etc. revert to the system font, display of all sorts of controls break down, massive crash shortly after). My Forms have few controls, but I do a lot of GDI+ drawing in User controls. What's a good way to tell how many handles I'm using, or even leaking? Thanks, David

  • Why is Html.DropDownList() producing <select name="original_name.name"> instead of just <select name

    - by DanM
    I have an editor template whose job is to take a SelectList as its model and build a select element in html using the Html.DropDownList() helper extension. I'm trying to assign the name attribute for the select based on a ModelMetadata property. (Reason: on post-back, I need to bind to an object that has a different property name for this item than the ViewModel used to populate the form.) The problem I'm running into is that DropDownList() is appending the name I'm providing instead of replacing it, so I end up with names like categories.category instead of category. Here is some code for you to look at... SelectList.ascx <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<System.Web.Mvc.SelectList>" %> <%= Html.DropDownList( (string)ViewData.ModelMetadata.AdditionalValues["PropertyName"], Model) %> Resulting HTML <select id="SkillLevels_SkillLevel" name="SkillLevels.SkillLevel"> <option value="1">High</option> <option value="2">Med</option> <option selected="selected" value="3">Low</option> </select> Expected HTML <select id="SkillLevels_SkillLevel" name="SkillLevel"> <option value="1">High</option> <option value="2">Med</option> <option selected="selected" value="3">Low</option> </select> Also tried <%= Html.Encode((string)ViewData.ModelMetadata.AdditionalValues["PropertyName"])%> ...which resulted in "SkillLevel" (not "SkillLevels.SkillLevel"), proving that the data stored in metadata is correct. and <%= Html.DropDownList( (string)ViewData.ModelMetadata.AdditionalValues["PropertyName"], Model, new { name = (string)ViewData.ModelMetadata.AdditionalValues["PropertyName"] }) %> ...which still resulted in <select name=SkillLevels.Skilllevel>. Questions What's going on here? Why does it append the name instead of just using it? Can you suggest a good workaround? Update: I ended up writing a helper extension that literally does a find/replace on the html text: public static MvcHtmlString BindableDropDownListForModel(this HtmlHelper helper) { var propertyName = (string)helper.ViewData.ModelMetadata.AdditionalValues["PropertyName"]; var compositeName = helper.ViewData.ModelMetadata.PropertyName + "." + propertyName; var rawHtml = helper.DropDownList(propertyName, (SelectList)helper.ViewData.Model); var bindableHtml = rawHtml.ToString().Replace(compositeName, propertyName); return MvcHtmlString.Create(bindableHtml); }

  • Ndepend CQL to query types out of assembly wildcard

    - by icelava
    In order to determine what low-level framework types a web application is directly using, one has to define each and every assembly involved. SELECT TYPES FROM ASSEMBLIES "Company.System.Framework", "Company.System.Framework.ReferenceLookup", "Company.System.Framework.Web", "Company.System.Framework.Security", "Company.System.Framework.Logging", "Company.System.Framework.DMS" WHERE IsDirectlyUsedBy "WebAssembly" I cannot find any syntax to wildcard the list of assemblies. Is there no way to shortcut this? We have a lot of framework level assemblies. i.e. Company.System.Framework.*

  • Creating a secure SQL Server 2008 database environment

    - by user279521
    I am in the process of setting up a corporate SQL Server 2008 database. The data on this machine will be related to financial services. There will be low level traffic (not like your average investment broker's website). However, a secure data environment is very crucial. What would I need to know / do in order to ensure that I have a secure database?

  • Matlab - binary vector with high concentration of 1s (or 0s)

    - by JohnIdol
    What's the best way to generate a number X of random binary vectors of size N with concentration of 1s (or, simmetrically, of 0s) that spans from very low to very high? Using randint or unidrnd (as in this question) will generate binary vectors with uniform distributions, which is not what I need in this case. Any help appreciated!

  • Short Python alphanumeric hash with minimal collisions

    - by ensnare
    I'd like to set non-integer primary keys for a table using some kind of hash function. md5() seems to be kind of long (32-characters). What are some alternative hash functions that perhaps use every letter in the alphabet as well as integers that are perhaps shorter in string length and have low collision rates? Thanks!

  • C# Confusing Results from Performance Test

    - by aip.cd.aish
    I am currently working on an image processing application. The application captures images from a webcam and then does some processing on it. The app needs to be real time responsive (ideally < 50ms to process each request). I have been doing some timing tests on the code I have and I found something very interesting (see below). clearLog(); log("Log cleared"); camera.QueryFrame(); camera.QueryFrame(); log("Camera buffer cleared"); Sensor s = t.val; log("Sx: " + S.X + " Sy: " + S.Y); Image<Bgr, Byte> cameraImage = camera.QueryFrame(); log("Camera output acuired for processing"); Each time the log is called the time since the beginning of the processing is displayed. Here is my log output: [3 ms]Log cleared [41 ms]Camera buffer cleared [41 ms]Sx: 589 Sy: 414 [112 ms]Camera output acuired for processing The timings are computed using a StopWatch from System.Diagonostics. QUESTION 1 I find this slightly interesting, since when the same method is called twice it executes in ~40ms and when it is called once the next time it took longer (~70ms). Assigning the value can't really be taking that long right? QUESTION 2 Also the timing for each step recorded above varies from time to time. The values for some steps are sometimes as low as 0ms and sometimes as high as 100ms. Though most of the numbers seem to be relatively consistent. I guess this may be because the CPU was used by some other process in the mean time? (If this is for some other reason, please let me know) Is there some way to ensure that when this function runs, it gets the highest priority? So that the speed test results will be consistently low (in terms of time). EDIT I change the code to remove the two blank query frames from above, so the code is now: clearLog(); log("Log cleared"); Sensor s = t.val; log("Sx: " + S.X + " Sy: " + S.Y); Image<Bgr, Byte> cameraImage = camera.QueryFrame(); log("Camera output acuired for processing"); The timing results are now: [2 ms]Log cleared [3 ms]Sx: 589 Sy: 414 [5 ms]Camera output acuired for processing The next steps now take longer (sometimes, the next step jumps to after 20-30ms, while the next step was previously almost instantaneous). I am guessing this is due to the CPU scheduling. Is there someway I can ensure the CPU does not get scheduled to do something else while it is running through this code?

  • Ndepend CQL to find methods of certain types using particular framework assembly

    - by icelava
    In order to check if types not derived from certain base classes are using a low-level framework assembly, the following query can be used. SELECT TYPES WHERE IsDirectlyUsing "ASSEMBLY:Framework.Data" AND !(DeriveFrom "App.BaseTypes.BusinessFacadeBase" OR DeriveFrom "App.BaseTypes.BusinessComponentBase" OR DeriveFrom "App.BaseTypes.DataAccessComponentBase") Now I wish to drill down further to see which methods from those classes are actually doing so. But the thing is if I change the query target from TYPES to METHODS then DeriveFrom is not going to apply. How can these criteria be preserved?
