  • Ubuntu won't save my settings for thinkpad trackpoint

    - by serve.chilled
    I'm using Ubuntu 12.04 on a Thinkpad X200. To configure the trackpoint, I use "configure TrackPoint". Unfortunately I can't make Ubuntu saving my settings (concerning the sensitivity etc.). Whenever I reboot the computer, it's set to generic settings again. I already tried htorque's answer to a similar question and created a new udev-rule for the trackpoint-settings but it didn't helped. So, how can I make theses settings permanent?

    - by Shawn Cicoria
    If you’re developing BizTalk 2009 solutions (Orchestrations) and you’ve split your schemas out into alternative assemblies (projects) – sometimes you’ll get odd not found issues with some (if not all) of the types in those referenced assemblies.  You can try everything – recompile, de-gac, re-gac, – doesn’t matter. Well there’s a hotfix for this: http://support.microsoft.com/kb/977428/en-us FIX: You experience various problems when you develop a BizTalk project that references another BizTalk project in Visual Studio on a computer that is running BizTalk Server 2009

  • How to use TFS as a query tracking system?

    - by deostroll
    We already use tfs for managing defects in code etc, etc. We additionally need a way to "understand the domain & requirements of the products". Normally, without tfs we exchange emails with the consultants and have the questions/queries answered. If it is a feature implementation we sometimes "find" conflicts in the implementation itself. And when that happens the userstory is modified and the enhancement/bug as per that is raised in TFS. Sometimes it is critical we come back to decisions we made or questions we wanted answers to. Hence we need to be able to track how that "requirement idea" or that "query in concern" evolved. Hence how is it that we can use TFS to track all of this? Do we raise an "issue" item for this? Or do we raise a "bug" item? The main things we'd ideally look in a query tracking system are as follows: Area: Can be a module, submodule, domain. Sometimes this may be "General" - to address domain related stuff, or, event more granular to address modules, sub-modules. Take the case for the latter, if we were tracking this in excel sheets, we'd just write module1,submodule2; i.e. in a comma separated fashion. The things I would like here is to be able search for all queries relating to submodule2 sometime in the future. Responses: This is a record of conversations between the consultant and any other stakeholder. For a simple case, it would just be paragraphs. Each para would start with a name and date enclosed in brackets and the response following that...each para would be like a thread - much like a forum thread Action taken: We'd want to know how the query was closed, what was the input given, what were the changes that took place because of that, etc etc. These are fields I think I would need in such a system apart from some obvious ones like status, address to, resovled by, etc. I am open for any other fields which are sort of important. To summarise my question: how can we manage "queries" in the system? Where should we ideally store data pertaining to those three fields I have mentioned above (for e.g. is it wise to store responses in the history tag assuming we are opening a bug for the query)?

  • Using ASP.NET Membership Provider with an ACL

    - by geekrutherford
    Up until recently one of my applications has used the membership provider within ASP.NET exclusively. However, it has been proposed that while the currently defined roles are beneficial, security needs to be more granular to restrict both access to certain pages and functionality present within a given page.   Unfortunately, the role based security ASP.NET gives you out of the box falls down in this area. This is not due to a lack of foresight by Microsoft, but rather it was simply not designed for implementing both role based security and any inherent ACL you may define within these roles. Mind you some would say an ACL is independent of the role to which a user belongs and is assigned to the user directly.   The application mentioned here has it's own User object (which encapsulates the membership provider user object as a property) and SQL Server table to store extended information not present in the aspnet_users table. While I could have modified the aspnet membership schema to suit the applications needs, it seemed smarter to simply create a separate table with a foreign key back to the aspnet_users table.   Since I have a separate object to store extended user information, I simply created an ACL object and expose it as a property of my user object.   This is all well and good, but it does not help in regards to the SiteMapProvider and restricting access at the page level based on the users ACL.   The straightforward answer would be to develop some code within the databound event for the menu that checks the page title and has hardcoded logic that dictates a user must have certain permissions turned on. The problem with this approach is that it's HARDCODED!!! If you need to change access to a page you'd need to do a build and go through your normal deployment process....ugh!!!   An alternative method, albeit not perfect, is to utilize the resourceKey property on the SiteMapNodes in the SiteMap file with the name of the required permission to view the page. Within the databound event for your menu you iterate the SiteMapNodes in the menus SiteMapProvider looking for a match at the page level based on title. When a match is detected, you have a switch/case on the SiteMapNodes resourceKey (the name of the ACL permission required). The case for the resourceKey ensures the users ACL permission is turned on and viola!!!   This is noteably not perfect in that it is using the resourceKey in a manner other than intended.  Since the application is not localized, using it in the manner described it not an issue.   Below is a sample SiteMap file with the resourceKey used as the ACL permission identifier:     Below is the ItemDataBound event. This application uses the Telerik Menu control:

  • Screen corruption with 946G / 82945G/GZ [closed]

    - by Ferdinandhi
    Since version 10.04 I have problems with Ubuntu (I think) my graphics card. This problem arises especially when working with graphics or CPU usage much. The problem is that it breaks the GUI as you see in the image and the entire computer is very slow. I'm running Ubuntu 11.04 and have a Intel graphics card 945G x86/MMX/SSE2. I used Unity and Gnome 3 with the same results. lspci returns 00:02.0 VGA compatible controller: Intel Corporation 82945G/GZ Integrated Graphics Controller (rev 02)

  • Making large scale changes to an economy in a social game

    - by Zach
    Are there any examples or case studies of social games, specifically on Facebook, where the developer has made drastic changes to the economy? I'm specifically interested in examples where the old economy was based off of purchasing items with Facebook credits then moving to a new model where the same inventory or similar inventory is sold with a soft currency. The closest comparisons I've been able to find so far are looking at iOS games that have gone from purchase models to freemium models, but haven't found a comparable scenario in a social game besides larger scale MMO's.

  • Does Google rate the webpage by amount of visits?

    - by petiar
    Hi there, there is quite extensive discussion about this topic on another website and I am really losing my confidence. The thing is that I claim that the amount (count) of visits is NOT a criteria for increasing the PR of the particular web because: a) Google just doesn't know about every single visit on a webpage (in case it's not using GA) b) Google just would not rate by something what Google actually affects Thanks for your opinions. Peter.

  • Software engineering and independence

    - by Mark
    I tend to think very independently, often coming up with unconventional, sometimes unorthodox, ways of solving problems. I do not like to listen to authority such as having to code up software a certain way or following strict guidelines/formats. Do you think the software engineering/development field would be very tough for someone like me who prefers autonomy? If not, what fields of computer science do allow for that?

  • vgaswitcheroo - switch GPU based on load?

    - by Primož Kralj
    Is it possible to make vgaswitcheroo switch between GPU based on load? For example, when computer would be in idle it would turn off discrete and use only integrated; when enough load would accumulate on it it would automatically turn on discrete graphics and disable integrated. My second question is whether there is any GUI applet or something that I could use to manually switch between GPUs - instead of manually echoing in switch file? Edit: I found answer to last question at https://help.ubuntu.com/community/HybridGraphics

  • Throwing exception from a property when my object state is invalid

    - by Rumi P.
    Microsoft guidelines say: "Avoid throwing exceptions from property getters", and I normally follow that. But my application uses Linq2SQL, and there is the case where my object can be in invalid state because somebody or something wrote nonsense into the database. Consider this toy example: [Table(Name="Rectangle")] public class Rectangle { [Column(Name="ID", IsPrimaryKey = true, IsDbGenerated = true)] public int ID {get; set;} [Column(Name="firstSide")] public double firstSide {get; set;} [Column(Name="secondSide")] public double secondSide {get; set;} public double sideRatio { get { return firstSide/secondSide; } } } Here, I could write code which ensures that my application never writes a Rectangle with a zero-length side into the database. But no matter how bulletproof I make my own code, somebody could open the database with a different application and create an invalid Rectangle, especially one with a 0 for secondSide. (For this example, please forget that it is possible to design the database in a way such that writing a side length of zero into the rectangle table is impossible; my domain model is very complex and there are constraints on model state which cannot be expressed in a relational database). So, the solution I am gravitating to is to change the getter to: get { if(firstSide > 0 && secondSide > 0) return firstSide/secondSide; else throw new System.InvalidOperationException("All rectangle sides should have a positive length"); } The reasoning behind not throwing exceptions from properties is that programmers should be able to use them without having to make precautions about catching and handling them them. But in this case, I think that it is OK to continue to use this property without such precautions: if the exception is thrown because my application wrote a non-zero rectangle side into the database, then this is a serious bug. It cannot and shouldn't be handled in the application, but there should be code which prevents it. It is good that the exception is visibly thrown, because that way the bug is caught. if the exception is thrown because a different application changed the data in the database, then handling it is outside of the scope of my application. So I can't do anything about it if I catch it. Is this a good enough reasoning to get over the "avoid" part of the guideline and throw the exception? Or should I turn it into a method after all? Note that in the real code, the properties which can have an invalid state feel less like the result of a calculation, so they are "natural" properties, not methods.

  • Stop trying to be perfect

    - by Kyle Burns
    Yes, Bob is my uncle too.  I also think the points in the Manifesto for Software Craftsmanship (manifesto.softwarecraftsmanship.org) are all great.  What amazes me is that tend to confuse the term “well crafted” with “perfect”.  I'm about to say something that will make Quality Assurance managers and many development types as well until you think about it as a craftsman – “Stop trying to be perfect”. Now let me explain what I mean.  Building software, as with building almost anything, often involves a series of trade-offs where either one undesired characteristic is accepted as necessary to achieve another desired one (or maybe stave off one that is even less desirable) or a desirable characteristic is sacrificed for the same reasons.  This implies that perfection itself is unattainable.  What is attainable is “sufficient” and I think that this really goes to the heart both of what people are trying to do with Agile and with the craftsmanship movement.  Simply put, sufficient software drives the greatest business value.   I've been in many meetings where “how can we keep anything from ever going wrong” has become the thing that holds us in analysis paralysis.  I've also been the guy trying way too hard to perfect some function to make sure that every edge case is accounted for.  Somewhere in there, something a drill instructor said while I was in boot camp occurred to me.  In response to being asked a question by another recruit having to do with some edge case (I can barely remember the context), he said “What if grasshoppers had machine guns?  Would the birds still **** with them?”  It sounds funny, but there's a lot of wisdom in those words.   “Sufficient” is different for every situation and it’s important to understand what sufficient means in the context of the work you’re doing.  If I’m writing a timesheet application (and please shoot me if I am), I’m going to have a much higher tolerance for imperfection than if you’re writing software to control life support systems on spacecraft.  I’m also likely to have less need for high volume performance than if you’re writing software to control stock trading transactions.   I’d encourage anyone who has read this far to instead of trying to be perfect, try to create software that is sufficient in every way.  If you’re working to make a component that is sufficient “better”, ask yourself if there is any component left that is not yet sufficient.  If the answer is “yes” you’re working on the wrong thing and need to adjust.  If the answer is “no”, why aren’t you shipping and delivering business value?

  • When to use Constants vs. Config Files to maintain Configuration

    - by CoffeeAddict
    I often fight with myself on whether to put certain keys in my web.config or in a Constants.cs class or something like this. For example if I wanted to store application specific keys for whatever the case may be..I could store it and grab it from my web config via custom keys or consume it by referencing a constant in my constants class. When would you want to use Constants over config keys? This question really applies to any language I think.

  • Get Info From Database, or Build Inferred Info?

    - by Zaemz
    Does it make more sense to store and retrieve properties or information directly related to an item in a database, or, say in such a case that a product's ID could describe information about it, should the information be gathered from that? Example: Item SKU -- 4HBU12 4 - is the number of motors H - the voltage B - the color, blue U - the model 12 - the length Should I store those individual attributes as well as the SKU, or should I store only the SKU and build the attributes from it?
