• Cannot install "ATI/AMD proprietary FGLRX graphics driver" (SystemError)

  - by Fisherman John

  I have just installed a fresh copy of 12.04.1 64bit. I formatted my PC completely and enabled updates during the installation. After the installation was complete, I went on updating my software. However, when I wanted to install the additional drivers using the Additional Drivers tool (namely "ATI/AMD proprietary FGLRX graphics driver"), it gave me this error: SystemError: E:Unable to correct problems, you have held broken packages. The same error shows up if I try installing the post-release updates driver. Installing the drivers from the terminal results in this output: XXXXXX:~$ sudo apt-get install fglrx [sudo] password for XXXXX: Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: fglrx : Depends: lib32gcc1 but it is not going to be installed Depends: libc6-i386 but it is not going to be installed E: Unable to correct problems, you have held broken packages." I get this using "sudo apt-get update": http://pastebin.com/AWAtDXjY But "sudo apt-get install fglrx" still get me this error: http://pastebin.com/RYM55bVN & "sudo apt-get -f install fglrx" gives me this error: http://pastebin.com/xxekajvP Any help would be greatly appreciated. (Please note that I'm new to Linux, coming directly from Windows. I have tried Ubuntu twice or so before, but it was not for a long period of time. The drivers got installed smoothly the few times I've tried Ubuntu, but post-release updates never worked for me.) [I am going to work now, so I can only answer from my phone. Can't really test any new solutions you may give me until ~10 hours from now on. Maybe more.] @stonedsquirrel When I try to run that command, I get this error: "XXXXXX:~$ sudo apt-get install fglrx [sudo] password for XXXXX: Reading package lists...

• Steam not displaying text on wine 1.5 running on Ubuntu 12.04

  - by Jscags

  Hello fellow dwellers of askubuntu, as the title says I'm having difficulties with getting Steam to run properly. I think I have the solution but I am pretty incompetent with Ubuntu (just started using it the other day) so a step by step process would be unbelievably appreciated! Here are the links to what I think possible solutions are: [1] https://bbs.archlinux.org/viewtopic.php?id=146223 [2] http://bugs.winehq.org/show_bug.cgi?id=31374 I've tried googling how to preform the solutions such as changing the alias/script for steam (no idea what that is) to -no-dwrite or launching with wine Steam.exe -no-dwrite. The dwrite seems to be the issue in all this but I can't for the life of me figure out how to do anything about it. Any useful input is what I'm hoping for but for the brave soul who feels like typing a bit more, perhaps a step-by-step list of instructions starting from downloading Steam off the official website, would be my saving grace. If there is any more info you guys need let me know and I'll of course be happy to oblige!

• Is it appropriate to try to control the order of finalization?

  - by Strilanc

  I'm writing a class which is roughly analogous to a CancellationToken, except it has a third state for "never going to be cancelled". At the moment I'm trying to decide what to do if the 'source' of the token is garbage collected without ever being set. It seems that, intuitively, the source should transition the associated token to the 'never cancelled' state when it is about to be collected. However, this could trigger callbacks who were only kept alive by their linkage from the token. That means what those callbacks reference might now in the process of finalization. Calling them would be bad. In order to "fix" this, I wrote this class: public sealed class GCRoot { private static readonly GCRoot MainRoot = new GCRoot(); private GCRoot _next; private GCRoot _prev; private object _value; private GCRoot() { this._next = this._prev = this; } private GCRoot(GCRoot prev, object value) { this._value = value; this._prev = prev; this._next = prev._next; _prev._next = this; _next._prev = this; } public static GCRoot Root(object value) { return new GCRoot(MainRoot, value); } public void Unroot() { lock (MainRoot) { _next._prev = _prev; _prev._next = _next; this._next = this._prev = this; } } } intending to use it like this: Source() { ... _root = GCRoot.Root(callbacks); } void TransitionToNeverCancelled() { _root.Unlink(); ... } ~Source() { TransitionToNeverCancelled(); } but now I'm troubled. This seems to open the possibility for memory leaks, without actually fixing all cases of sources in limbo. Like, if a source is closed over in one of its own callbacks, then it is rooted by the callback root and so can never be collected. Presumably I should just let my sources be collected without a peep. Or maybe not? Is it ever appropriate to try to control the order of finalization, or is it a giant warning sign?

• Data structures for storing finger/stylus movements in drawing application?

  - by mattja?øb

  I have a general question about creating a drawing application, the language could be C++ or ObjectiveC with OpenGL. I would like to hear what are the best methods and practices for storing strokes data. Think of the many iPad apps that allow you to draw with your finger (or a stylus) or any other similar function on a desktop app. To summarize, the data structure must: be highly responsive to the movement store precise values (close in space / time) usable for rendering the strokes with complex textures (textures based on the dynamic of the stroke etc) exportable to a text file for saving/loading

• Opinion: Seeking the One True Linux: Is Linux Distro-hopping a Thing of the Past?

  Distro-hopping is easy and fun. Linux users distro-hop to solve problems and to try new software. But is it necessary? Haven't most Linux distributions reached a state of polish that makes distro-hopping unnecessary? Brian Proffitt wonders if distro-hopping shouldn't be discouraged.

• [EF + Oracle] Inserting Data (1/2)

  - by JTorrecilla

  Prologue Following EF series (I ,II y III) in this chapter we will see how to create DB record from EF. Inserting Data Like we indicated in the 2º post: “One Entity matches with a DB record, and one property match with a Table Column”. To start, we need to create an object from one of the Entities: 1: EMPLEADOS empleado = new EMPLEADOS(); Also like, I told previously, Exists the possibility to use the Static Function defined by VS for each Entity: Once we have created the object, we can Access to it properties to fill like a common class:   1: empleado.NOMBRE = "Javier Torrecilla";   After finish of fill our Entity properties, it must be needed to add the object to the appropriate ObjectSet in the ObjectContext: 1: enti.EMPLEADOS.AddObject(empleado); or 1: enti.AddToEMPLEADOS(empleado); Both methods will do the same action, create an insert statement. Have we finished? No. Any Entity has a property called “EntityState”. This prop is an Enum from “EntityState”, which has the following: Detached: the Entity is created, but not added to the Context. Unchanged: There is no pending changes in the Entity. Added: The entity is added to the ObjectSet, but it is not yet sent to the DB. Deleted: The object is deleted form the ObjectSet, but not yet from the DB. Modified: There is Pending Changes to confirm. Let’s see, the several values of the property during the Creation steps: 1. While the Object is created and we are filling the props: EntityState.Detached; 2. After adding to the ObjectSet: EntityState.Added. This not indicated that the record is in the DB 3. Saving the Data: To sabe the data in the DB, we are going to call “SaveChanges” method of the Object Context. After invoke it, the property will be EntityState.Unchanged.   What does SaveChanges Method? This function will synchronize and send all pending changes to DB. It will add, modify or delete all Entities, whose EntityState property, is setted to Added, Deleted or Modified. After finishing, all added or modified entities will be change the State to “Unchanged”, and deleted Entities must take the “Detached” state.

• Good SEO - Why is Good SEO Better Than Its Evil 'Black Hat' Brother?

  With the rise of today's technology, a number of bad and dodgy practices have come into play that can seriously put your website at risk from being banned in the search engines - no questions asked. The constant shift of techniques and 'state of flux' the search engines remain in makes it difficult to differentiate between good and bad SEO.

• box2d and constant movement

  - by Arnas

  i'm developing a game with a top down view, the players body is a circle. To move the character you need to tap on the screen and it moves to the spot. To achieve this i'm saving the coordinate of the touch and call a method every frame which applies linear velocity to the body with a vector of the direction the body should go _body->SetLinearVelocity(b2Vec2((a.x - currPos.x)/SPEED_RATIO,(size.height - a.y - currPos.y)/SPEED_RATIO)); //click position - current position, screen height - click position (since the y axis is flipped, (0,0) is in the bottom left ) - current position = vector of the direction we want to go now the problem with this is that the body slows down until it finally stops when getting closer to the point we want it to go, since the closer we are to that point the lenght of the vector gets smaller. Besides that i've read that it's bad practice to set linear velocity in box2d and i should use apply force instead, but that way the forces would add up and overshoot the target where it's supposed to stop. So what i'm asking is how to move a box2d body to a coordinate in constant speed.

• what extension for uploading drawings from gimp to facebook

  - by joel

  Today I upgraded to Ubuntu 13.10 from 13.04. It looks good. I didn't test Gimp Image Editor on the 13.04 version but I just tested the 13.10 version with a painting with Gimp and when I tried to upload the file to facebook it tells me that this is an invalid image. I have an older laptop with ubuntu 12.04 and have the same Gimp installed in it. With the 12.04 version I have plenty of extensions for filing the images that I do on gimp and can upload them to facebook. I noticed that the 13.10 version has only a few extensions for saving a file from gimp. Which extension should I use to save a file that facebook will accept in this 13.10 version?

• What are some ways of making manageable complex AI?

  - by Tetrad

  In the past I've used simple systems like finite state machines (FSMs) or hierarchical FSMs to control AI behavior. For any complex system, this pattern falls apart very quickly. I've heard about behavior trees and it seems like that's the next obvious step, but haven't seen a working implementation or really tried going down that route yet. Are there any other patterns to making manageable yet complex AI behaviors?

• Modern workflow / project architecture with PHP

  - by Sprottenwels

  I wonder how one professional developer would design the backend-part of his application. I try to use PHP as seldom as possible and only for data serving/saving purposes. To do so, i would create a module/class for every greater part of my application, then write some single script files which are called by javascript. E.g: User clicks a "retrieve data" button javascript will call retrieveData.php retrieveData.php will create an instance of the needed class, then executes myInstance-retrieve() the data is returned to my JS by retrieveData.php However, i see some disadvantages in this practice: I will need a single scipt file for every action, (e.g retrieveData.php, saveData.php etc) I need a man-in-the-middle step: from JS to my single script, to my classes How are modern applications designed to accomplish what i need to do?

• Two problems, both with either lock or suspend.

  - by user199208

  I recently did two things that may be the cause of either of them. 1) I started using a second screen 2) I installed xscreensaver instead of the stock, power saving option. My first question is about suspend: every time I wake from suspend, networking is disabled. While I've seen multiple posts about that on here, it didn't start happening until recently. Second, lock seems to be disabled now. Are both of these problems a bug, or was this caused by the second screen or maybe xscreensaver?

• What is hiberfil.sys and How Do I Delete It?

  - by The Geek

  You’re no doubt reading this article because there’s a gigantic hiberfil.sys file sitting in the root of your drive, and you want to get rid of it to free up some space… but you can’t! Luckily, you actually can delete it, and today we’ll show you how. The more memory you have in your PC, the bigger the file will be. So What is hiberfil.sys Anyway? Windows has two power management modes that you can choose from: one is Sleep Mode, which keeps the PC running in a low power state so you can almost instantly get back to what you were working on. The other is Hibernate mode, which completely writes the memory out to the hard drive, and then powers the PC down entirely, so you can even take the battery out, put it back in, start back up, and be right back where you were. Hibernate mode uses the hiberfil.sys file to store the the current state (memory) of the PC, and since it’s managed by Windows, you can’t delete the file. So if you never use it, and want to disable Hibernate mode, keep reading. Personally I stick with Sleep Mode the vast majority of the time, but I do use Hibernate quite often. Disable Hibernate (and Delete hiberfil.sys) in Windows 7 or Vista You’ll need to open an administrator mode command prompt by right-clicking on the command prompt in the start menu, and then choosing Run as Administrator. Once you’re there, type in the following command: powercfg -h off You should immediately notice that the Hibernate option is gone from the Shut down menu. You’ll also notice that the file is magically gone! For more about dealing with Hibernate like setting how long it takes to head into Hibernate mode, you can check out our article on How to Manage Hibernate Mode in Windows 7. Disabling Hibernate Mode in Windows XP It’s a lot easier in Windows XP to get rid of Hibernate mode… in fact, we’ve already covered it before, but we’ll cover it again. Just head into Control Panel –> Power Options, and then find the Hibernate tab. Uncheck the box, reboot your PC, and then you can delete the hiberfil.sys file.

• Should Scala IDE Worksheets be part of your open git repository?

  - by JacobusR

  Those familiar with Scala IDE will know about the great testing environment offered by the Scala Worksheet. You can scribble and scratch, much like in the REPL, but with all the goodness added by the IDE as a whole (refactoring, saving, error checking, etc). When you create a worksheet, it is created with the .sc extension, and also creates a artifact under a hidden directory called .worksheet. This is all fine and dandy, but should one include these in your public .git repositories? People who does not use Scala IDE (or older versions) may find these files confusing. On the other hand, making some of your experiments public to developers who are using Scala IDE, may give them a quick start into experimenting and learning the project.

• A Simple Entity Tagger

  - by Elton Stoneman

  In the REST world, ETags are your gateway to performance boosts by letting clients cache responses. In the non-REST world, you may also want to add an ETag to an entity definition inside a traditional service contract – think of a scenario where a consumer persists its own representation of your entity, and wants to keep it in sync. Rather than load every entity by ID and check for changes, the consumer can send in a set of linked IDs and ETags, and you can return only the entities where the current ETag is different from the consumer’s version.  If your entity is a projection from various sources, you may not have a persistent ETag, so you need an efficient way to generate an ETag which is deterministic, so an entity with the same state always generates the same ETag. I have an implementation for a generic ETag generator on GitHub here: EntityTagger code sample. The essence is simple - we get the entity, serialize it and build a hash from the serialized value. Any changes to either the state or the structure of the entity will result in a different hash. To use it, just call SetETag, passing your populated object and a Func<> which acts as an accessor to the ETag property: EntityTagger.SetETag(user, x => x.ETag); The implementation is all in at 80 lines of code, which is all pretty straightforward: var eTagProperty = AsPropertyInfo(eTagPropertyAccessor); var originalETag = eTagProperty.GetValue(entity, null); try { ResetETag(entity, eTagPropertyAccessor); string json; var serializer = new DataContractJsonSerializer(entity.GetType()); using (var stream = new MemoryStream()) { serializer.WriteObject(stream, entity); json = Encoding.UTF8.GetString(stream.GetBuffer(), 0, (int)stream.Length); } var guid = GetDeterministicGuid(json); eTagProperty.SetValue(entity, guid.ToString(), null); //... There are a couple of helper methods to check if the object has changed since the ETag value was last set, and to reset the ETag. This implementation uses JSON to do the serializing rather than XML. Benefit - should be marginally more efficient as your hashing a much smaller serialized string; downside, JSON doesn't include namespaces or class names at the root level, so if you have two classes with the exact same structure but different names, then instances which have the same content will have the same ETag. You may want that behaviour, but change to use the XML DataContractSerializer if you think that will be an issue. If you can persist the ETag somewhere, it will save you server processing to load up the entity, but that will only apply to scenarios where you can reliably invalidate your ETag (e.g. if you control all the entry points where entity contents can be updated, then you can calculate and persist the new ETag with each update).

• Determine Better Coding Practice

  - by footprint.

  As a new programmer, it has always been hard to create applications, because I am still at the learning stage. I understand that to achieve a particular affect or function in an application, there will be numerous ways to achieve the same result. However, should I just purely create a function to it's working state, which means that as long as it works, just as the way I want it to, then it should be fine. Can any fellow programmers of a higher level kindly let me know the right way of doing things?

• Is there any hard data on the (dis-)advantages of working from home?

  - by peterchen

  Is there any hard data (studies, comparisons, not-just-gut-feel analysis) on the advantages and disadvantages of working from home? My devs asked about e.g. working from home one day per week, the boss doesn't like it for various reasons, some of which I agree with but I think they don't necessarily apply in this case. We have real offices (2..3 people each), distractions are still common. IMO it would be beneficial for focus, and with 1 day / week, there wouldn't be much loss at interaction and communication. In addition it would be a great perk, and saving the commute. Related: Pros and Cons of working Remotely/from Home (interesting points, but no hard facts) [edit] Thanks for all the feedback! To clarify: it's not my decision to make, I agree that there are pro's and con's depending on circumstances, and we are pushing for "just try it". I've asked this specific question because (a) facts are a good addition to thoughts in arguing with an engineer boss, and (b) we, as developers, should build upon facts like every respectable trade.

• How can I make zaz save its profile data?

  - by RolandiXor - The Ice Man

  I've been playing Zaz recently as a time waster and stress beater, but it seems not to be actively maintained, and is not saving profile data under Ubuntu 12.10. It's getting to be more stressful than fun, because it keeps crashing, and under Unity, Gnome Shell, KDE (in other words, any opengl enabled WM) it makes the GPU lockup. How can I make it save the profile data or create a profile that I can manually place my level info in? I'm tired of playing the same levels over and over and not being able to start from the ones I've already passed. I am still yet to find any info on fixing this. Any clues?

• Need instructions on how to create wpa_supplicant.conf and add fast_reauth=0 to it

  - by nutty about natty

  Like many other natty users on a university/academic network, I'm experiencing annoying frequent disconnects/hangs/delays. See, for instance here. I would like to learn how to add fast_reauth=0 to the wpa_supplicant.conf file. This file, it seems, does not exit by default, and needs to be manually created first: README You will need to make a configuration file, e.g. /etc/wpa_supplicant.conf, with network configuration for the networks you are going to use. Further, I installed wpa_gui which probably needs to be launched with parameters, else it's pretty blank... What I'm hoping for is this: That creating a wpa_supplicant.conf file with fast_reauth=0 in it, saving it to the relevant path, will work and make my uni wireless (more or even completely) stable. I read mixed reviews about wicd (as an alternative to the network manager). Also note that on my basic wlan at home (with bog-standard wpa encryption) the connection is stable. Thanks!

• Visual C++, CMap object save to blob column

  - by ilansch

  I have a MFC CMap object, each object stores 160K~ entries of long data. I need to store it on Oracle SQL. we decided to save it as a blob. since we do not want to make additional table. we also thought about saving it as local file and point the SQL column to that file, but we rather just keep it as blob on the server and clear the table every couple of weeks. The table has a sequential key as ID, and 2 column of time. I need to add the blob column in order to store on every row that CMap. Can you recommend a guide to do so (read/write Map to blob or maybe a clob) ? Thanks.
