  • xorg-edgers PPA with llvmpipe breaks AMD APU system

    - by linux_RRT
    I've read before where this had happened to another user with the same system... I was running Ubuntu 12.04 LTS with Kernel 3.2.0.29 and decided to give xorg-edgers a try. I purged fglrx* and xorg* before beginning. I upgraded with sudo apt-get upgrade -d The system downloaded and installed 109MB worth of data to the system, including llvmpipe which I am very unfamiliar with, and Kernel 3.5.0.11. The system was then rebooted to finalize the upgrade. The system boots to a black screen and then tells me "The system is running in low-graphics mode". Did I miss a step in the install? Or do the newest open-source drivers just not work with my hardware? I realize this hardware (APU) is some of the newer development. I dropped to command via the fallback menu and attempted to boot lightdm as root, but the system hangs in 'Configuring kernel parameters' at Starting initializes zram swaping. ...and then it just sits there. The other thing that concerns me is the output at the top of the screen that says: could not write bytes: Broken pipe Does llvmpipe work for this type of system? To be clear the system is: MSI x370-206us Laptop Radeon HD 6320 AMD e450 APU 1.67ghz dual-core Any help would be much appreciated. Like I said, I'm pretty sure I followed the right order of operations for the install procedure, but I was curious if anyone with similar hardware had experienced anything similar.

  • Data classes: getters and setters or different method design

    - by Frog
    I've been trying to design an interface for a data class I'm writing. This class stores styles for characters, for example whether the character is bold, italic or underlined. But also the font-size and the font-family. So it has different types of member variables. The easiest way to implement this would be to add getters and setters for every member variable, but this just feels wrong to me. It feels way more logical (and more OOP) to call style.format(BOLD, true) instead of style.setBold(true). So to use logical methods insteads of getters/setters. But I am facing two problems while implementing these methods: I would need a big switch statement with all member variables, since you can't access a variable by the contents of a string in C++. Moreover, you can't overload by return type, which means you can't write one getter like style.getFormatting(BOLD) (I know there are some tricks to do this, but these don't allow for parameters, which I would obviously need). However, if I would implement getters and setters, there are also issues. I would have to duplicate quite some code because styles can also have a parent styles, which means the getters have to look not only at the member variables of this style, but also at the variables of the parent styles. Because I wasn't able to figure out how to do this, I decided to ask a question a couple of weeks ago. See Object Oriented Programming: getters/setters or logical names. But in that question I didn't stress it would be just a data object and that I'm not making a text rendering engine, which was the reason one of the people that answered suggested I ask another question while making that clear (because his solution, the decorator pattern, isn't suitable for my problem). So please note that I'm not creating my own text rendering engine, I just use these classes to store data. Because I still haven't been able to find a solution to this problem I'd like to ask this question again: how would you design a styles class like this? And why would you do that? Thanks on forehand!

  • Nordics OTN ACE Tour 2013 - Recap

    - by Mike Dietrich
    The Nordics OTN ACE Tour 2013 with stops in Stockholm, Ballerup/Copenhagen and Oslo is over. A very intense week with plenty of excellent presentations from Lonneke Dikmans, Sten Vesterli, Tim Hall and others. I'm always impressed how much those people know and how good they present. It's such a great learning experience. And there's always some time to talk about weired things apart from the Oracle cosmos. So thanks a lot, folks - it was a pleasure to travel with you. And many many thanks also to the people from ORCAN, DOUG and OUGN. Everything worked out so well. And thanks for the great gifts. the dinners, everything!!! Of course a special thanks to all the people who went to my presentations. Hope you've enjoyed it - and sorry for any overtiming But as Tim said yesterday in the Shuttle Bus back to the airport: "45 min slots don't work out at all" The final slide set about "Different Ways to Upgrade, Migrate and Consolidate into Oracle Database 12c including Oracle Multitenant, New Features and other stuff" can be downloaded via this link. Hope to see you all again soon - and let me know once you have successfully upgraded to Oracle Database 12c or in case you'd like to become one of our Upgrade Reference Customers. Cheers - Mike PS: One thing I couldn't really understand - why is that thing below not labeled simply GRAPE JUICE??? And who's honestly drinking that?

  • How to create a copy of an instance without having access to private variables

    - by Jamie
    Im having a bit of a problem. Let me show you the code first: public class Direction { private CircularList xSpeed, zSpeed; private int[] dirSquare = {-1, 0, 1, 0}; public Direction(int xSpeed, int zSpeed){ this.xSpeed = new CircularList(dirSquare, xSpeed); this.zSpeed = new CircularList(dirSquare, zSpeed); } public Direction(Point dirs){ this(dirs.x, dirs.y); } public void shiftLeft(){ xSpeed.shiftLeft(); zSpeed.shiftRight(); } public void shiftRight(){ xSpeed.shiftRight(); zSpeed.shiftLeft(); } public int getXSpeed(){ return this.xSpeed.currentValue(); } public int getZSpeed(){ return this.zSpeed.currentValue(); } } Now lets say i have an instance of Direction: Direction dir = new Direction(0, 0); As you can see in the code of Direction, the arguments fed to the constructor, are passed directly to some other class. One cannot be sure if they stay the same because methods shiftRight() and shiftLeft could have been called, which changes thos numbers. My question is, how do i create a completely new instance of Direction, that is basically copy(not by reference) of dir? The only way i see it, is to create public methods in both CircularList(i can post the code of this class, but its not relevant) and Direction that return the variables needed to create a copy of the instance, but this solution seems really dirty since those numbers are not supposed to be touched after beeing fed to the constructor, and therefore they are private.

  • Does your programming knowledge decrease if you don't practice?

    - by Codereview
    I'm a beginner programmer, I study languages such as C/C++/Python and Java (Mainly focused on C++). I'm What you'd call "Young and inexperienced" and I admit that because I can't claim otherwise. As a student I have many other problems besides programming.I practice programming as often as I can, and especially because my teacher gives me a lot more exercises than the rest of the class (It's a very low level), so oftentimes I spend weeks doing something else such as school projects or sports, or travelling, anything besides programming. Don't get me wrong though, I love programming, I love to build functional code, to watch as a program comes alive at the push of a button and to learn as much as I can - I simply don't have much time for it. Straight to the question, now: does your programming knowledge decrease as time passes and you don't practice? You may ask "How much time do you mean?". I don't mean a specific amount of time, but for reference you could take a month-two or even a year as an example. By knowledge I mean anything: From syntax to language functionality.

  • Extract all related class type aliasing and enum into one file or not

    - by Chen OT
    I have many models in my project, and some other classes just need the class declaration and pointer type aliasing. It does not need to know the class definition, so I don't want to include the model header file. I extract all the model's declaration into one file to let every classes reference one file. model_forward.h class Cat; typedef std::shared_ptr<Cat> CatPointerType; typedef std::shared_ptr<const Cat> CatConstPointerType; class Dog; typedef std::shared_ptr<Dog> DogPointerType; typedef std::shared_ptr<const Dog> DogConstPointerType; class Fish; typedef std::shared_ptr<Fish> FishPointerType; typedef std::shared_ptr<const Fish> FishConstPointerType; enum CatType{RED_CAT, YELLOW_CAT, GREEN_CAT, PURPLE_CAT} enum DogType{HATE_CAT_DOG, HUSKY, GOLDEN_RETRIEVER} enum FishType{SHARK, OCTOPUS, SALMON} Is it acceptable practice? Should I make every unit, which needs a class declaration, depends on one file? Does it cause high coupling? Or I should put these pointer type aliasing and enum definition inside the class back? cat.h class Cat { typedef std::shared_ptr<Cat> PointerType; typedef std::shared_ptr<const Cat> ConstPointerType; enum Type{RED_CAT, YELLOW_CAT, GREEN_CAT, PURPLE_CAT} ... }; dog.h class Dog { typedef std::shared_ptr<Dog> PointerType; typedef std::shared_ptr<const Dog> ConstPointerType; enum Type{HATE_CAT_DOG, HUSKY, GOLDEN_RETRIEVER} ... } fish.h class Fish { ... }; Any suggestion will be helpful.

  • Dynamically setting a value in XAML page:

    - by kaleidoscope
    This is find that I came across while developing the Silverlight screen for MSFT BPO Invoice project. Consider an instance wherein I am calling a xaml page as a popup in my parent xaml. And suppose we wanted to dynamically set a textbox field in the parent page with the  values that we select from the popup xaml. I tried the following approaches to achieve the above scenario: 1. Creating an object of the parent page within the popup xaml and initializing its textbox field.         ParentPage p = new ParentPage();         ParentPage.txtCompCode.Text = selectedValue; 2. Using App app = (App)Application.Current and storing the selected value in app. 3. Using IsolatedStorage All the above approaches failed to produce the desired effect since in the first case I did not want the parent page to get initialized over and over again and furthermore in all the approaches the value was not spontaneously rendered on the parent page. After a couple of trials and errors I decided to tweak the g.cs file of the Parent xaml. *.g.cs files are autogenerated and their purpose is to wire xaml-element with the code-behind file. This file is responsible for having reference to xaml-elements with the x:Name-property in code-behind. So I changed the access modifier of supposed textbox fields to 'static' and then directly set the value in popup xaml page as so: ParentPage.txtCompCode.Text = selectedValue; This seemed to work perfectly. We can access any xaml's g.cs file by going to the definition of InitializeComponent() present in the constructor of the xaml. PS: I may have failed to explore other more efficient ways of getting this done. So if anybody does find a better alternative please feel free to get back to me. Tinu

    Color identifiers make it easier for developers to quickly read and understand the code on screen.  One of the many features provided by JustCode is the ability to colorize additional items that Visual Studio does not allow you to colorize by default.  The colorization of items such as methods, properties, events, variables, and method parameters can easily be tweaked to your specific needs. Enable / Disable Color Identifiers In the recent release, we turned this option on by default.  You can enable/disable code colorization by going to the JustCode menu in Visual Studio, selecting options, then selecting the general section in the left window.  When you scroll down on general setting you will see a check box that says Color Identifiers.  Check or uncheck this box to enable/disable code colorization.    Color identifiers option   Adjust Color Identifiers Adjusting the color identifiers in JustCode is done in the same place ...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • Why does working processors harder use more electrical power?

    - by GazTheDestroyer
    Back in the mists of time when I started coding, at least as far as I'm aware, processors all used a fixed amount of power. There was no such thing as a processor being "idle". These days there are all sorts of technologies for reducing power usage when the processor is not very busy, mostly by dynamically reducing the clock rate. My question is why does running at a lower clock rate use less power? My mental picture of a processor is of a reference voltage (say 5V) representing a binary 1, and 0V representing 0. Therefore I tend to think of of a constant 5V being applied across the entire chip, with the various logic gates disconnecting this voltage when "off", meaning a constant amount of power is being used. The rate at which these gates are turned on and off seems to have no relation to the power used. I have no doubt this is a hopelessly naive picture, but I am no electrical engineer. Can someone explain what's really going on with frequency scaling, and how it saves power. Are there any other ways that a processor uses more or less power depending on state? eg Does it use more power if more gates are open? How are mobile / low power processors different from their desktop cousins? Are they just simpler (less transistors?), or is there some other fundamental design difference?

  • Hired developer insists on doing things the wrong way

    - by Tariq- iPHONE Programmer
    Hello, i am working with Social Networking iphone app which require remote data connection. So i hired a php developer in order to provide me RESTful services. But when i start working with him, he arguing me that he will not make stored procedures and web services. Instead of he suggested me to pass query as a parameter. Suppose If I have to call Search service, he told me to send POST request with 3 parameters: Query="select * from users", username=abd and password = 123 And i thing there is no such architecture in order to use remote data. Then he is saying it is possible through socket programming. And I am 100% sure this is not an appropriate way to access remote data. This is simply illogical. Thousands of iphone application using REST/SOAP services to make remote data connection He just declined me to provide RESTful services. Please its my heartily advice to all developers that post your own views over here. So that I can show to that developers that these are the views from all developers worldwide.

  • Why the clip space in OpenGL has 4 dimensions?

    - by user827992
    I will use this as a generic reference, but the more i browser online docs and books, the less i understand about this. const float vertexPositions[] = { 0.75f, 0.75f, 0.0f, 1.0f, 0.75f, -0.75f, 0.0f, 1.0f, -0.75f, -0.75f, 0.0f, 1.0f, }; in this online book there is an example about how to draw the first and classic hello world for OpenGL about making a triangle. The vertex structure for the triangle is declared as stated in the code above. The book, as all the other sources about this, stress the point that the Clip Space is a 4D structure that is used to basically decide what will be rasterized and rendered to the screen. Here I have my questions: i can't imagine something in 4D, i don't think that a human can do that, what is a 4D for this Clip space ? the most human-readable doc that i have read speaks about a camera, which is just an abstraction over the clipping concept, and i get that, the problem is, why not using the concept of a camera in the first place which is a more familiar 3D structure? The only problem with the concept of a camera is that you need to define the prospective in other way and so you basically have to add another statement about what kind of camera you wish to have. How i'm supposed to read this 0.75f, 0.75f, 0.0f, 1.0f ? All i get is that they are all float values and i get the meaning of the first 3 values, what does it mean the last one?

I want to create a University Information Search for prospective students who are trying to look for an affordable University to attend. It will depend on the student's family income and the grades they get. They enter in those two parameters (and some more) and it comes up with a list of suitable Unis based on their criteria. This is not about the price of tution fee. It's mostly to do with the cost of living. Stuff like: Rent (if living in a private flat). Student Accomadation. Cost of traveling to your home and back (for holidays). ...and some other stuff stuff I haven't thought about yet. It'll mostly be GUI driven with some textual information. I'm also thinking of using it as a website interface. What do you guys think? Can I program something like this Java? If there's any holes you see in my idea please tell me.

  • LDoms with Solaris 11

    - by Orgad Kimchi
    Oracle VM Server for SPARC (LDoms) release 2.2 came out on May 24. You can get the software, see the release notes, reference manual, and admin guide here on the Oracle VM for SPARC page. Oracle VM Server for SPARC enables you to create multiple virtual systems on a single physical system.Each virtual system is called alogical domain and runs its own instance of Oracle Solaris 10 or Oracle Solaris 11. The version of the Oracle Solaris OS software that runs on a guest domain is independent of the Oracle Solaris OS version that runs on the primary domain. So, if you run the Oracle Solaris 10 OS in the primary domain, you can still run the Oracle Solaris 11 OS in a guest domain, and if you run the Oracle Solaris 11 OS in the primary domain, you can still run the Oracle Solaris 10 OS in a guest domain In addition to that starting with the Oracle VM Server for SPARC 2.2 release you can migrate guest domain even if source and target machines have different processor type. You can migrate guest domain from a system with UltraSPARC  T2+ or SPARC T3 CPU to a system with a SPARC T4 CPU.The guest domain on the source and target system must run Solaris 11 In order to enable cross CPU migration.In addition to that you need to change the cpu-arch property value on the source system. For more information about Oracle VM Server for SPARC (LDoms) with Solaris 11 and  Cross CPU Migration refer to the following white paper

  • Functional programming compared to OOP with classes

    - by luckysmack
    I have been interested in some of the concepts of functional programming lately. I have used OOP for some time now. I can see how I would build a fairly complex app in OOP. Each object would know how to do things that object does. Or anything it's parents class does as well. So I can simply tell Person().speak() to make the person talk. But how do I do similar things in functional programming? I see how functions are first class items. But that function only does one specific thing. Would I simply have a say() method floating around and call it with an equivalent of Person() argument so I know what kind of thing is saying something? So I can see the simple things, just how would I do the comparable of OOP and objects in functional programming, so I can modularize and organize my code base? For reference, my primary experience with OOP is Python, PHP, and some C#. The languages that I am looking at that have functional features are Scala and Haskell. Though I am leaning towards Scala. Basic Example (Python): Animal(object): def say(self, what): print(what) Dog(Animal): def say(self, what): super().say('dog barks: {0}'.format(what)) Cat(Animal): def say(self, what): super().say('cat meows: {0}'.format(what)) dog = Dog() cat = Cat() dog.say('ruff') cat.say('purr')

  • Select (loop) or command not working in shell-script

    - by user208098
    I've been tinkering with Linux and Unix for years but still a novice in my mind and recently find myself trying to be more pro with it as I work in IT. So with that notion I'm studying shell scripting. I've hit a snag in ubuntu using the latest version 13.10 Saucy. When I use the select command in a sh script it doesn't work, depending on how I format the command it will either return Unexpected "do" or Unexpected "done". See the following two examples: This section of code produces an unexpected "do" error: #/bin/bash PS3='Please enter your choice' select opt in option1 option2 option3 quit do case $opt in "option1") echo "you chose choice 1" ;; "option2") echo "you chose choice 2" ;; "option3") echo "you chose choice 3" ;; "quit") break ;; *) echo invalid option ;; esac done This section of code produces an unexpected "done" error. #/bin/bash PS3='Please enter your choice' select opt in option1 option2 option3 quit ; do case $opt in "Option1") echo "you chose choice 1" ;; "Option2") echo "you chose choice 2" ;; "Option3") echo "you chose choice 3" ;; "quit") break ;; *) echo invalid option ;; esac done When I enter these parameters into the command line interactively or manually I get the desired result which is a list of choices to choose from. However when executed from a script I get the before mentioned errors. Also a side note I have tried this in Fedora as a script and it worked perfectly so my question is why isn't it working in Ubuntu, is this a difference between RHL and Debian? Or is it a bug in the latest version of Ubuntu? Thanks in advance for any help! KG

  • SQL SERVER – FIX ERROR – Cannot connect to . Login failed. The login is from an untrusted domain and cannot be used with Windows authentication. (Microsoft SQL Server, Error: 18452)

    - by pinaldave
    Just a day ago, I was doing small attempting to connect to my local SQL Server using IP 127.0.0.1. The IP is of my local machine and SQL Server is installed on the local box as well. However, whenever I try to connect to the server it gave me following strange error. Cannot connect to 127.0.0.1. Login failed. The login is from an untrusted domain and cannot be used with Windows authentication. (Microsoft SQL Server, Error: 18452) The reason was indeed strange as I was trying to connect from local box to local box and it said my login was from an untrusted domain. As my system is not part of any domain, this was really confusing to me. Another thing was that I have been always able to connect always using 127.0.0.1 to SQL Server and this was a bit strange to me. I started to think what did I change since it  last time I connected to SQL Server. Suddenly I remembered that I had modified my computer’s host file for some other purpose. Solution: I opened my host file and immediately added entry like 127.0.0.1 localhost. Once I added it I was able to reconnect to SQL Server as usual. The location of the host file is C:\Windows\System32\drivers\etc. You will find file with the name hosts in it, make sure to open it with notepad. If you are part of a domain and your organization is using active directory, make sure that your account is added properly to active directory as well have proper security permissions to execute the task.

  • How can Agile methodologies be adapted to High Volume processing system development?

    - by luckyluke
    I am developing high volume processing systems. Like mathematical models that calculate various parameters based on millions of records, calculated derived fields over milions of records, process huge files having transactions etc... I am well aware of unit testing methodologies and if my code is in C# I have no problem in unit testing it. Problem is I often have code in T-SQL, C# code that is a SQL stored assembly, and SSIS workflow with a good amount of logic (and outcomes etc) or some SAS process. What is the approach YOu use when developing such systems. I usually develop several tests as Stored procedures in a designed schema(TEST) and then automatically run them overnight and check out the results. But this is only for T-SQL. And Continous integration IS hard. But the problem is with testing SSIS packages. How do You test it? What is Your preferred approach for stubbing data into tables (especially if You need a lot data initialization). I have some approach derived over the years but maybe I am just not reading enough articles. So Banking, Telecom, Risk developers out there. How do You test your mission critical apps that process milions of records at end day, month end etc? What frameworks do You use? How do You validate that Your ssis package is Correct (as You develop it)/ How do You achieve continous integration in such an environment (Personally I never got there)? I hope this is not to open-ended question. How do You test Your map-reduce jobs for example (i do not use hadoop but this is quite similar). luke Hope that this is not too open ended

  • What to do when 'dpkg --configure -a' fails with too many errors?

    - by rudivonstaden
    During an upgrade from lucid (10.04) to precise (12.04), the X session froze, and I have been trying to recover the upgrade to get a stable system. I have performed the following steps: Used ssh to log in to the stalled system over the network. Checked the contents of the /var/log/dist-upgrade directory. There was no activity on main.log, apt.log or term.log. top showed that process 'precise' was using about 3% CPU, but I could find no evidence that the upgrade process was still doing anything. 'dpkg' did not show up in top, but it came up with pgrep dpkg | xargs ps Killed the 'dpkg' and 'precise' processes Tried to recover the upgrade by running sudo fuser -vki /var/lib/dpkg/lock;sudo dpkg --configure -a. This was partially successful (some packages were configured), but failed with the message Processing was halted because there were too many errors. I ran the same command a few times, and each time some packages were configured but others failed. Tried running sudo apt-get -f install. It fails with similar errors to dpkg. The current situation is that dpkg --configure -a and sudo apt-get -f install fails with two kinds of error: Dependency issues, e.g.: dpkg: dependency problems prevent configuration of cifs-utils: cifs-utils depends on samba-common; however: Package samba-common is not configured yet. dpkg: error processing cifs-utils (--configure): dependency problems - leaving unconfigured Resource conflict, e.g.: debconf: DbDriver "config": /var/cache/debconf/config.dat is locked by another process: Resource temporarily unavailable Additionally, it seems there's reference to potential boot problems, so I'm not keen to reboot without fixing the install first: dpkg: too many errors, stopping Processing triggers for initramfs-tools ... update-initramfs: Generating /boot/initrd.img-3.2.0-25-generic cryptsetup: WARNING: failed to detect canonical device of /dev/sda1 cryptsetup: WARNING: could not determine root device from /etc/fstab So my question is, how to get a working install when dpkg --configure -a fails?

  • what's the difference between Routed Events and Attached Events?

    - by vverma01
    I tried to find through various sources but still unable to understand difference between routed events and attached events in WPF. Most of the places of reference for attached event following example is used: <StackPanel Button.Click="StackPanel_Click"> <Button Content="Click Me!" Height="35" Width="150" Margin="5" /> </StackPanel> Explained as: stack panel do not contain Click event and hence Button.Click event is attached to Stack Panel. Where as msdn says: You can also name any event from any object that is accessible through the default namespace by using a typename.event partially qualified name; this syntax supports attaching handlers for routed events where the handler is intended to handle events routing from child elements, but the parent element does not also have that event in its members table. This syntax resembles an attached event syntax, but the event here is not a true attached event. Instead, you are referencing an event with a qualified name. According to MSDN information as pasted above, the above example of Buttons and StackPanel is actually a routed event example and not true attached event example. In case if above example is truly about usage of attached event (Button.Click="StackPanel_Click") then it's in contradiction to the information as provided at MSDN which says Another syntax usage that resembles typename.eventname attached event syntax but is not strictly speaking an attached event usage is when you attach handlers for routed events that are raised by child elements. You attach the handlers to a common parent, to take advantage of event routing, even though the common parent might not have the relevant routed event as a member. A similar question was raised in this Stack Overflow post, but unfortunately this question was closed before it could collect any response. Please help me to understand how attached events are different from routed events and also clarify the ambiguity as pointed above.
