• Could not log-in properly but shows no error in joomla

  - by saeha

  This is what I did, I added variables in \libraries\joomla\database\table\user.php: var $img_content= null; //contains the blob type data var $img_name = null; var $img_type = null; then I added this code in \components\com_user\controller.php: $file = JRequest::getVar( 'pic', '', 'files', 'array' ); if(isset($file['name'])) { jimport('joomla.filesystem.file'); $fileName = $file['name']; $tmpName = $file['tmp_name']; $fileSize = $file['size']; $fileType = $file['type']; $fp = fopen($tmpName, 'r'); $content = fread($fp, filesize($tmpName)); //$content = addslashes($content); fclose($fp); $user->set('img_name', $fileName); $user->set('img_type', $fileType); $user->set('img_content', $content); } that works fine, but I found this problem in logging in with the new user with an uploaded photo, other user with an empty img_content field could login properly. What happens is when I log-in using the user with uploaded photo, it's not redirecting properly it just return to log-in, but when i log-in through backend using other user which is super admin, i could see that user which appears as logged in. I started saving the images in the database because I am having problem with the directory when I have uploaded the site. I think the log-in was affected by the blob type data in the database. Could that be the problem? What could be the solution? -saeha

• Upgrade to Ubuntu 13.10 in a VirtualBox: Gnome desktop not working

  - by Xavier

  I had Ubuntu 13.04 running in a VirtualBox (the host is WinXP). I've upgraded it to 13.10 but I've some issues: Gnome desktop is not working correctly (I can log in but the main menu bar remains empty - I can only log out with CTRL-ALT-BACKSPACE) I cannot build and install the VirtualBox Guest Addons: When trying to build it, it says: me@virtuntu:/etc/init.d$ sudo ./vboxadd setup Removing existing VirtualBox DKMS kernel modules ...done. Removing existing VirtualBox non-DKMS kernel modules ...done. Building the VirtualBox Guest Additions kernel modules The headers for the current running kernel were not found. If the following module compilation fails then this could be the reason. Building the main Guest Additions module ...done. Building the shared folder support module ...fail! (Look at /var/log/vboxadd-install.log to find out what went wrong) Doing non-kernel setup of the Guest Additions ...done. In the log file, I see the following error: /tmp/vbox.0/dirops.c:292:5: error: unknown field ‘readdir’ specified in initializer .readdir = sf_dir_read, ^ /tmp/vbox.0/dirops.c:292:5: warning: initialization from incompatible pointer type [enabled by default] /tmp/vbox.0/dirops.c:292:5: warning: (near initialization for ‘sf_dir_fops.flush’) [enabled by default] make[2]: *** [/tmp/vbox.0/dirops.o] Erreur 1 make[1]: *** [_module_/tmp/vbox.0] Erreur 2 make: *** [vboxsf] Erreur 2 Creating user for the Guest Additions.

• Why is testing MVC Views frowned upon?

  - by Peter Bernier

  I'm currently setting the groundwork for an ASP.Net MVC application and I'm looking into what sort of unit-tests I should be prepared to write. I've seen in multiple places people essentially saying 'don't bother testing your views, there's no logic and it's trivial and will be covered by an integration test'. I don't understand how this has become the accepted wisdom. Integration tests serve an entirely different purpose than unit tests. If I break something, I don't want to know a half-hour later when my integration tests break, I want to know immediately. Sample Scenario : Lets say we're dealing with a standard CRUD app with a Customer entity. The customer has a name and an address. At each level of testing, I want to verify that the Customer retrieval logic gets both the name and the address properly. To unit-test the repository, I write an integration test to hit the database. To unit-test the business rules, I mock out the repository, feed the business rules appropriate data, and verify my expected results are returned. What I'd like to do : To unit-test the UI, I mock out the business rules, setup my expected customer instance, render the view, and verify that the view contains the appropriate values for the instance I specified. What I'm stuck doing : To unit-test the repository, I write an integration test, setup an appropriate login, create the required data in the database, open a browser, navigate to the customer, and verify the resulting page contains the appropriate values for the instance I specified. I realize that there is overlap between the two scenarios discussed above, but the key difference it time and effort required to setup and execute the tests. If I (or another dev) removes the address field from the view, I don't want to wait for the integration test to discover this. I want is discovered and flagged in a unit-test that gets multiple times daily. I get the feeling that I'm just not grasping some key concept. Can someone explain why wanting immediate test feedback on the validity of an MVC view is a bad thing? (or if not bad, then not the expected way to get said feedback)

• RPi and Java Embedded GPIO: Using Java to read input

  - by hinkmond

  Now that we've learned about using Java code to control the output of the Raspberry Pi GPIO ports (by lighting up LEDs from a Java app on the RPi for now and noting in the future the same Java code can be used to drive industrial automation or medical equipment, etc.), let's move on to learn about reading input from the RPi GPIO using Java code. As before, we need to start out with the necessary hardware. For this exercise we will connect a Static Electricity Detector to the RPi GPIO port and read the value of that sensor using Java code. The circuit we'll use is from William J. Beaty and is described at this Web link. See: Static Electricity Detector He calls it an "Electric Charge" detector, which is a bit misleading. A Field Effect Transistor is subject to nearby electro-magnetic fields, such as a static charge on a nearby object, not really an electric charge. So, this sensor will detect static electricity (or ghosts if you are into paranormal activity ). Take a look at the circuit and in the next blog posts we'll step through how to connect it to the GPIO port of your RPi and then how to write Java code to access this fun sensor. Hinkmond

• What happened to the Journal of Game Development?

  - by Ricket

  The lengthy mission statement from its website states: The lack of game-specific research has prevented many in the academic community from embracing game development as a serious field of study. The Journal of Game Development (JOGD), however, provides a much-needed, peer-reviewed, medium of communication and the raison d'etre for serious academic research focused solely on game-related issues. The JOGD provides the vehicle for disseminating research and findings indigenous to the game development industry. It is an outlet for peer-reviewed research that will help validate the work and garner acceptance for the study of game development by the academic community. JOGD will serve both the game development industry and academic community by presenting leading-edge, original research, and theoretical underpinnings that detail the most recent findings in related academic disciplines, hardware, software, and technology that will directly affect the way games are conceived, developed, produced, and delivered. The Journal of Game Development was established in 2003. It's hard to find any information about the issues but at four issues per year, I estimate the last issue was distributed sometime in 2005 or 2006. It had a good editorial board of college professors and a founding editor from Ubisoft. The list of articles looks good. The price was reasonable. So what happened to it? Its website recently went down but you can see the last Archive.org version. The editor-in-chief is a professor at my school so I intend to ask him in person in a week or two, but I thought I'd see what you might be able to dig up about it first. Of course I will be sure to add an answer with his official word on the matter at that time.

• How to change circular icon to indicate chosen session in unity-greeter?

  - by Chan-Ho Suh

  In Precise (12.04), when I login to lightdm, using the unity-greeter, there's a white circle by my name. For the standard DEs like Unity or XFCE, the circle has a representative icon (Ubuntu symbol or little mouse resp.). I have a session for Awesome window manager which was added when I installed Awesome, but it just shows a blank white circle. I'd like to know how to add an icon to it, or at least some indicator, as unity-greeter doesn't show you what session is set until you click on the circle. I found another question about changing the session names. The answer for it said to change the names in the desktop files in /usr/share/xsessions. Unfortunately, while there is an icon field in those desktop files, they are all blank (Caveat: I no longer have Unity installed, so maybe the Unity one would not be blank. But the Xubuntu desktop file has it blank even though the icon shows in unity-greeter). Update: Here's the png I use as a badge for Awesome. It's not great, but looks reasonably nice: []

• I need advice on laptop purchase for university [closed]

  - by Systemic33

  I'm currently in University studying Computer Science/IT/Information Technology. And this first year i've managed to do with the laptop I had; an ASUS Eee PC 1000H with a 10.1" screen. But this is getting way too underpowered and small for programming more than just quick programming introduction excercises. So I'm looking to buy a more suitable laptop. It's not supposed to be a desktop replacement though, since I've got a pretty good desktop already with a 24" monitor. So the kinda laptop I want to buy is one suited for university. If this bears any significance, I'm working in Java atm, but I will likely work with lots of other things incl. web development. I'm looking to spend about $1700 plus/minus. And it should be powerful/big enough for working on programming projects as well as the usual university stuff like MATLAB, Maple, etc out "in the field", and sometimes for maybe a week when visiting my parents. What I'm looking at right now is the ASUS Zenbook UX31A with the 1920 x 1080 resolution on 13.3" IPS display. But I'm kinda nervous that this will be too petite for programming. In essence i'm looking for a powerfull computer, that has good enough battery, and looks good. I would love suggestions or any type of feedback, either with maybe a better choice, or input on how its like programming on 13" laptops. Very much thanks in advance for anyone who even went through all that! PS. I don't want a mac, or my inner karma would commit Seppuku xD But experiences from working on the 13" Macbook Air would kinda be equivalent to the Zenbook i'm considering, so I would love to hear that. tl;dr The quick brown fox jumps over the lazy dog ;)

• How AlphaBlend Blendstate works in XNA when accumulighting light into a RenderTarget?

  - by cubrman

  I am using a Deferred Rendering engine from Catalin Zima's tutorial: His lighting shader returns the color of the light in the rgb channels and the specular component in the alpha channel. Here is how light gets accumulated: Game.GraphicsDevice.SetRenderTarget(LightRT); Game.GraphicsDevice.Clear(Color.Transparent); Game.GraphicsDevice.BlendState = BlendState.AlphaBlend; // Continuously draw 3d spheres with lighting pixel shader. ... Game.GraphicsDevice.BlendState = BlendState.Opaque; MSDN states that AlphaBlend field of the BlendState class uses the next formula for alphablending: (source × Blend.SourceAlpha) + (destination × Blend.InvSourceAlpha), where "source" is the color of the pixel returned by the shader and "destination" is the color of the pixel in the rendertarget. My question is why do my colors are accumulated correctly in the Light rendertarget even when the new pixels' alphas equal zero? As a quick sanity check I ran the following code in the light's pixel shader: float specularLight = 0; float4 light4 = attenuation * lightIntensity * float4(diffuseLight.rgb,specularLight); if (light4.a == 0) light4 = 0; return light4; This prevents lighting from getting accumulated and, subsequently, drawn on the screen. But when I do the following: float specularLight = 0; float4 light4 = attenuation * lightIntensity * float4(diffuseLight.rgb,specularLight); return light4; The light is accumulated and drawn exactly where it needs to be. What am I missing? According to the formula above: (source x 0) + (destination x 1) should equal destination, so the "LightRT" rendertarget must not change when I draw light spheres into it! It feels like the GPU is using the Additive blend instead: (source × Blend.One) + (destination × Blend.One)

• Woman Is the World's First Computer Programmer? [closed]

  - by Sveta Bondarenko

  This week, on 10th December, we celebrate the 197th birth anniversary of Ada Lovelace, often considered as the world's first computer programmer. Ada became famous not only as a daughter of romantic poet Lord Byron but also as an outstanding 19th century mathematician. Her works on analytical engine are recognized as the first algorithm intended to be processed by a machine. Women always played a crucial role in the computer science evolution, but unfortunately, they are considered to be not so good at programming and engineering as men. Even though the fair sex makes up a growing portion of computer and Internet users, there is still a large gender gap in the field of Computer Science. But all is not lost! According to the study women's enrollment in the computer science raised from 7 percent in 1995 to 42 percent in 2000. And it is still increasing. Soon women will take a well-deserved position among the world's top computer programmers. After all, a number of notable female computer pioneers such as Ada Lovelace, Grace Hopper, and Anita Borg have proven that women make great computer scientists. But will women make great contributions to the modern technologies industry? Or successful and famous female computer programmer is just a pipe dream?

• Convience of mySQL over xml

  - by Bonechilla

  Currently I use XML to store specific information to correctly load a few things such as a list of specfied characters, scenes and music, Once more I use JAXB in combination with standard compression/decompression(ZIP) functionality to store a list of extrenous data. This data is called to add functionality to the character, somewhat like Skills in an RPG. Each skill is seperated into its own XML file with a grandlist which contains the names of each file with their extensions omitted and zipped in folder that gets encrypted. At first using xml was working fine however as the skill list grow i worry about its stability. I was wondering if I should begin storing the data in mySQL. Originally I planned to simply convert everything to JSON over xml but i think possibly mySQL would be a better move. Can anyone inform me of the key difference and pros and cons of each I guess i'm looking for the best way to store the data more conviently and would be easier to operate on. The data is mostly primatives and strings and the only arraylist of values i have i can just concat into a single field and parse later

• How broad should a computer science/engineering student go?

  - by AskQuestions

  I have less than 2 years of college left and I still don't know what to focus on. But this is not about me, this is about being a future developer. I realize that questions like "Which language should I learn next?" are not really popular, but I think my question is broader than that. I often see people write things like "You have to learn many different things. Being a developer is not about learning one programming language / technology and then doing that for the rest of your life". Well, sure, but it's impossible to really learn everything thoroughly. Does that mean that one should just learn the basics of everything and then learn some things more thoroughly AFTER getting a particular job? I mean, the best way to learn programming is by actually programming stuff... But projects take time. Does an average developer really switch between (for example) being a web developer, doing artificial intelligence and machine learning related stuff and programming close to the hardware? I mean, I know a lot of different things, but I don't feel proficient in any of those things. If I want to find a job as a web developer (that's just an example) after I finish college, shouldn't I do some web related project (maybe using something I still don't know) rather than try to learn functional programming? So, the question is: How broad should a computer science student's field of focus be? One programming language is surely far too narrow, but what is too broad?

• What are the boundaries of the product owner in scrum?

  - by Saeed Neamati

  In another question, I asked about why I feel scrum turns active developers into passive developers, and it seems that the overall problem is not scrumy (related to scrum), and rather it's related to the bad implementation of scrum. So, here I have some questions about the scope of the responsibilities of PO (product owner) and the limitations he/she shouldn't pass. Should PO interfere the UI design, when there are designers at work in scrum team? (an example of this which has happened to us, is to replace checkboxes with a drop down list with two items, namely, yes and no; or to make some boxes larger, or to left-align some content instead of centering them on the page, or stuff like that). If yeah, to what extent? Colors? Layout? Should PO interfere in Design and architecture of coding? This hasn't happened to us yet, but I'm really curious about the boundaries. For example does PO has the right to change the platform (moving from ASP.NET MVC to PHP, or something like that), or choosing the count of servers (tier architecture), etc. Should PO interfere in validation mechanisms? For example, this field should be required, or we don't need to get this piece of information from user. Sometimes, analyzers and designers confirm that something can be handled behind the scene, like extracting the user profile info from another source, instead of asking for it in UI. How granular could/should PO get into the analysis and design? For example, a user story might be: "As a customer, I'd like to be able to buy new domains online". However, scrum team can implement this user story in a wizard of five steps, or in one single page. To which level PO should monitor, or govern, or supervise the technical analysis, design, and implementation? I asked these questions to judge whether our implementation is right or wrong?

• How to remove seams from a tile map in 3D?

  - by Grimshaw

  I am using my OpenGL custom engine to render a tilemap made with Tiled, using a well spread tileset from the web. There is nothing fancy going on. I load the TMX file from Tiled and generate vertex arrays and index arrays to render the tilemap. I am rendering this tilemap as a wall in my 3D world, meaning that I move around with a fly camera in my 3D world and at Z=0 there is a plane showing me my tiles. Everything is working correctly but I get ugly seems between the tiles. I've tried orthographic and perspective cameras and with either I found particular sets of parameters for the projection and view matrices where the artifacts did not show, but otherwise they are there 99% of the time in multiple patterns, depending on the zoom and camera parameters like field of view. Here's a screenshot of the artifact being shown: http://i.imgur.com/HNV1g4M.png Here's the tileset I am using (which Tiled also uses and renders correctly): http://i.imgur.com/SjjHK4q.png My tileset has no mipmaps and is set to GL_NEAREST and GL_CLAMP_TO_EDGE values. I've looked around many articles in the internet and nothing helped. I tried uv correction so the uv fall at half of the texel, rather than the end of the texel to prevent interpolating with the neighbour value(which is transparency). I tried debugging with my geometry and I verified that with no texture and a random color in each tile, I don't seem to see any seams. All vertices have integer coordinates, i.e, the first tile is a quad from (0,0) to (1,1) and so on. Tried adding a little offset both to the UV and to the vertices to see if the gaps cease to exist. Disabled multisampling too. Nothing fixed it so far. Thanks.

• Static "LoD" hack opinions

  - by David Lively

  I've been playing with implementing dynamic level of detail for rendering a very large mesh in XNA. It occurred to me that (duh) the whole point of this is to generate small triangles close to the camera, and larger ones far away. Given that, rather than constantly modifying or swapping index buffers based on a feature's rendered size or distance from the camera, it would be a lot easier (and potentially quite a bit faster), to render a single "fan" or flat wedge/frustum-shaped planar mesh that is tessellated into small triangles close to the near or small end of the frustum and larger ones at the far end, sort of like this (overhead view) (Pardon the gap in the middle - I drew one side and mirrored it) The triangle sizes are chosen so that all are approximately the same size when projected. Then, that mesh would be transformed to track the camera so that the Z axis (center vertical in this image) is always aligned with the view direction projected into the XZ plane. The vertex shader would then read terrain heights from a height texture and adjust the Y coordinate of the mesh to match a height field that defines the terrain. This eliminates the need for culling (since the mesh is generated to match the viewport dimensions) and the need to modify the index and/or vertex buffers when drawing the terrain. Obviously this doesn't address terrain with overhangs, etc, but that could be handled to a certain extent by including a second mesh that defines a sort of "ceiling" via a different texture. The other LoD schemes I've seen aren't particularly difficult to implement and, in some cases, are a lot more flexible, but this seemed like a decent quick-and-dirty way to handle height map-based terrain without getting into geometry manipulation. Has anyone tried this? Opinions?

• Using Groovy Aggregate Functions in ADF BC

  - by Sireesha Pinninti

  This article explains how groovy aggregate functions(sum, count, min, max and avg) can be used in ADF Business components and demonstrates how these can be used at entity and view level Let's consider EMP and DEPT tables and an usecase to track number of employees in each department   Entity-Level To use aggregate functions at entity level, we need to have association between entities representing master and child relationship and the destination accessor name is what we are going to use in our groovy Syntax: <Accessor>.count(Groovyexpression) - Note down the destination accessor name(EMP) in the association or AccessorAttribute name in source entity - Add a transient attribute in source entity with persistent property set to false and provide the groovy expression in the syntax provided above - Finally, Add newly added attribute to view object View-Level To use aggregate functions at view level, we need to have a view link between viewobjects representing master and child relationship and the destination accessor name is what we are going to use in our groovy Syntax: <ViewLinkAccessor>.count(Groovyexpression) - Note down the destination accessor name(EmpView) in the view link or viewLinkAccessor name in source view - Add a transient attribute in view object and provide a groovy aggregate function count as a value to it in the syntax provided above Now, If you run application module tester and execute DeptView / ViewLink, you should see employee count in EmpCount field  In similar way, one can use other groovy aggregate functions sum, avg, min and max.

• how to link a c++ object to a local variable in Lua

  - by MahanGM

  I'm completing my scripting interface with Lua, but recently I've stuck at some point. I have several functions for my Entitiy events like Update(). I have a function called create_entitiy() which instantiate a new entity from a given entity index: function Update() local bullet = create_entity(0, 0, "obj_bullet") end create_entity returns a table which is the properties of the created entity. Now how can I make a connection between bullet variable and my newly created object? Right now for previously added objects to the scene, I simply set a global table for each of them and then after every call to Update(), I go through registered names to find object tables and perform new changes. Like the one below: function Update() if keyboard_key_press(vk_right) then obj_player.x += 3 end I can get obj_player table because I know its name from C++, plus I can get it as a global table and simply reach for the first instance named obj_player. Is there any solution for me to make bullet variable act like this? I was thinking to get all local variables in Update() function and check for every one to see if is it table and it has an unique field attached to it like id, this way I can determine that this is an object table and do the rest of the process. By the way, is this interface going to work easier with luaBind if I implement it? Bottom line: How can I make a local variable in Lua that receives a table from create_entity function and track that local variable to capture it from C++. e. g. function Update() local bullet = create_entity(0, 0, "obj_bullet") bullet.x = 10 <== Commit a change in table end Now I want to get variable bullet from C++. And it's not just this variable, there might be a ton of these local variables with different names.

• MMORPG design for time-limited players

  - by Philipp

  I believe that there is a significant market of players who would enjoy the exploration and interaction aspects of MMORPGs, but simply don't have the time for the endless grinding marathons which are part of the average MMORPG. MMORPGs are all about interaction between players. But when different players have different amounts of time to invest into a game, those with less time to spend will soon lack behind their power-leveling friends and won't be able to interact with them anymore. One way to solve this would be to limit the progress a player can achieve per day, so that it simply doesn't make sense to play more than one or two hours a day. But even the busiest casual players sometimes like to spend a whole sunday afternoon playing a video game. Just stopping them after two hours would be really frustrating. It also creates a pressure to use the daily progress limit every day, because otherwise the player would feel like wasting something. This pressure would be detrimental for casual gamers. What else could be done to level the playing field between those players who play 40+ hours a week and those who can't play more than 10?

• Changing State in PlayerControler from PlayerInput

  - by Jeremy Talus

  In my player input I wanna change the the "State" of my player controller but I have some trouble to do it my player input is declared like that : class ResistancePlayerInput extends PlayerInput within ResistancePlayerController config(ResistancePlayerInput); and in my playerControler I have that : class ResistancePlayerController extends GamePlayerController; var name PreviousState; DefaultProperties { CameraClass = class 'ResistanceCamera' //Telling the player controller to use your custom camera script InputClass = class'ResistanceGame.ResistancePlayerInput' DefaultFOV = 90.f //Telling the player controller what the default field of view (FOV) should be } simulated event PostBeginPlay() { Super.PostBeginPlay(); } auto state Walking { event BeginState(name PreviousStateName) { Pawn.GroundSpeed = 200; `log("Player Walking"); } } state Running extends Walking { event BeginState(name PreviousStateName) { Pawn.GroundSpeed = 350; `log("Player Running"); } } state Sprinting extends Walking { event BeginState(name PreviousStateName) { Pawn.GroundSpeed = 800; `log("Player Sprinting"); } } I have tried to use PCOwner.GotoState(); and ResistancePlayerController(PCOwner).GotoState(); but won't work. I have also tried a simple GotoState, and nothing happen how can I call GotoState for the PC Class from my player input ?

• What data to send when tracking clicks with Google Analytics events (and how)?

  - by user359650

  When tracking clicks on links, there are 3 items I'm interested in: link location in the page by grabbing the id of the closest parent: to see influence of location on click-through link text: to see influence of text on click-through link href attribute value: to see where people go when leaving my website The problem when using Google Analytics to track those clicks is that events only have 3 available text fields, one of which being the category, which if you use to store one of the above items will create a mess in your Event reporting because you will have as many categories as item values. Therefore if you assign a predefined value to the category (e.g. clicks), then you're left with only 2 event fields (action, label) to store 3 items (location, text, href). That in itself isn't the end of the world because you can concatenate 2 items into 1 event field, then use the reporting or the API to filter things out. Accordingly what I plan on doing is this: category: clicks action: {location_on_page} ¦ {text} label: {href} where {__} are variable values related to the clicked links With this I can easily create some reports directly via the GUI: downloads: include only events where label ends with .pdf click outs to particular domains: include only events where label contains domain And for more complex tasks I need to export the data (or use the API): influence of location on clicks: for each location in the design, count number of events that have that location in the action, then corroborate with pageviews of the corresponding pages. Whilst this looks good I'm wondering if there is a better approach, hence the following questions: Q1: Can you foresee any particular issues with this particular setup (e.g. things I won't be able to report on)? Q2: Can you think of other data that would be interesting to include in the event?

• Lightning fast forum based around metadata / tags? [closed]

  - by Dan W

  Possible Duplicate: What Forum Software should I use? I wonder if anything like this exists. I'd like to add a forum to my site, but instead of the usual forum/subforum/sub-subforum structure, I'd like to use a metadata/tag approach where everything exists as a single directory, and where there's a search field at the top which instantly (<0.5 sec) filters the threads to a particular keyword or keywords. Also, as the admin, I would be able to add highly visible buttons at the top, which can be clicked on for the main categories I choose for the forum (nevertheless, users can also add tags to their own threads outside of these default main tags I supply if they wish). This approach, if done properly, is more powerful, efficient, maintenance free, scalable and friendly than a standard forum, so I was hoping someone had the same idea and made something out of it. It couldn't be that hard. I'd want the speed to be up to (or near) the standard of this: http://forum.dlang.org/ Other forums (e.g.: phpBB) are orders of magnitude worse than that in terms of latency (posting or browsing), and I think that is wrong, even in principle ;)

• Energy Firms Targetted for Sensitive Documents

  - by martin.abrahams

  Numerous multinational energy companies have been targeted by hackers who have been focusing on financial documents related to oil and gas field exploration, bidding contracts, and drilling rights, as well as proprietary industrial process documents, according to a new McAfee report. "It ... speaks to quite a sad state of our critical infrastructure security. These were not sophisticated attacks ... yet they were very successful in achieving their goals," said Dmitri Alperovitch, McAfee's vice president for threat research. Apparently, the attacks can be traced back over several years, creating a sustained security compromise that has provided access to highly sensitive information that is of huge financial value to competitors. The value of IRM as an additional layer of protection is clear. Whether your infrastructure security is in a sad state or is state of the art, breaches are always a possibility - and in any case, a lot of sensitive information is shared with third parties whose infrastructure security might not be as good as yours. IRM protects the individual information assets directly so that, even if infrastructure security is compromised, your critical information is enrypted and trackable and only accessible to authenticated, authorised, audited users. The full McAfee report is available here.

• What to Return with Async CRUD methods

  - by RualStorge

  While there is a similar question focused on Java, I've been in debates with utilizing Task objects. What's the best way to handle returns on CRUD methods (and similar)? Common returns we've seen over the years are: Void (no return unless there is an exception) Boolean (True on Success, False on Failure, exception on unhandled failure) Int or GUID (Return the newly created objects Id, 0 or null on failure, exception on unhandled failure) The updated Object (exception on failure) Result Object (Object that houses the manipulated object's ID, Boolean or status field to with success or failure indicated, Exception information if there was one, etc) The concern comes into play as we've started moving over to utilizing C# 5's Async functionality, and this brought the question up of how we should handle CRUD returns large-scale. In our systems we have a little of everything in regards to what we return, we want to make these returns standardized... Now the question is what is the recommended standard? Is there even a recommended standard yet? (I realize we need to decide our standard, but typically we do so by looking at best practices, see if it makes sense for us and go from there, but here we're not finding much to work with)
