• I can't get grub menu to show up during boot

  - by wim

  After trying (and failing) to install better ATI drivers in 11.10, I've somehow lost my grub menu at boot time. The screen does change to the familiar purple colour, but instead of a list of boot options it's just blank solid colour, and then disappears quickly and boots into the default entry normally. How can I get the bootloader back? I've tried sudo update-grub and also various different combinations of resolutions and colour depths in startupmanager application with no success (640x480, 1024x768, 1600x1200, 16 bits, 8 bits, 10 second delay, 7 second delay, 2 second delay...) edit: I have already tried holding down Shift during bootup and it does not seem to change the behaviour. I get the message "GRUB Loading" in the terminal, but then the place where the grub menu normally appears I get a solid blank magenta screen for a while. Here are the contents of /etc/default/grub # If you change this file, run 'update-grub' afterwards to update # /boot/grub/grub.cfg. # For full documentation of the options in this file, see: # info -f grub -n 'Simple configuration' GRUB_DEFAULT=0 GRUB_HIDDEN_TIMEOUT=0 GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=10 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" GRUB_CMDLINE_LINUX=" vga=798 splash" # Uncomment to enable BadRAM filtering, modify to suit your needs # This works with Linux (no patch required) and with any kernel that obtains # the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...) #GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef" # Uncomment to disable graphical terminal (grub-pc only) #GRUB_TERMINAL=console # The resolution used on graphical terminal # note that you can use only modes which your graphic card supports via VBE # you can see them in real GRUB with the command `vbeinfo' #GRUB_GFXMODE=640x480 # Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux #GRUB_DISABLE_LINUX_UUID=true # Uncomment to disable generation of recovery mode menu entries #GRUB_DISABLE_RECOVERY="true" # Uncomment to get a beep at grub start #GRUB_INIT_TUNE="480 440 1"

• Computer Says No: Mobile Apps Connectivity Messages

  - by ultan o'broin

  Sharing some insight into connectivity messages for mobile applications. Based on some recent ethnography done my myself, and prompted by a real business case, I would recommend a message that: In plain language, briefly and directly tells the user what is wrong and why. Something like: Cannot connect because of a network problem. Affords the user a means to retry connecting (or attempts automatically). Mobile context of use means users use anticipate interruptibility and disruption of task, so they will try again as an effective course of action. Tells the user when connection is re-established, and off they go. Saves any work already done, implicitly. (Bonus points on the ADF critical task setting scale) The following images showing my experience reading ADF-EMG Google Groups notification my (Android ICS) Samsung Galaxy S2 during a loss of WiFi give you a good idea of a suitable kind of messaging user experience for mobile apps in this kind of scenario. Inline connection lost message with Retry button Connection re-established toaster message The UX possible is dependent on device and platform features, sure, so remember to integrate with the device capability (see point 10 of this great article on mobile design by Brent White and Lynn Hnilo-Rampoldi) but taking these considerations into account is far superior to a context-free dumbed down common error message repurposed from the desktop mentality about the connection to the server being lost, so just "Click OK" or "Contact your sysadmin.".

• How to avoid jumping to a solution when under pressure? [closed]

  - by GlenPeterson

  When under a particularly strict programming deadline (like an hour), if I panic at all, my tendency is to jump into coding without a real plan and hope I figure it out as I go along. Given enough time, this can work, but in an interview it's been pretty unsuccessful, if not downright counter-productive. I'm not always comfortable sitting there thinking while the clock ticks away. Is there a checklist or are there techniques to recognize when you understand the problem well enough to start coding? Maybe don't touch the keyboard for the first 5-10 minutes of the problem? At what point do you give up and code a brute-force solution with the hope of reasoning out a better solution later? When is it most productive to think and design more vs. code some experiments to and figure out the design later? Here is a list of techniques for taking a math test and another for taking an oral exam. Is there is a similar list of techniques for handling a programming problem under pressure? ANSWERS: I think this is a valid answer: How To Solve It. I found the link as an answer to Steps to solve or approach towards a solution. There were also some really good tips at Is thinking out loud during an interview really the best strategy?. A great and concise argument for TDD is the first answer to TDD Writing code vs Figuring out the answer to a problem?. My question may be a near-duplicate of that one.

• vim + Ruby on Rails: how do you bounce among those 4-5 files you're currently working on?

  - by glitch

  I'm just starting to get familiar with vim, and I'd like to use it as my primary Rails development tool. As a Visual Studio and RubyMine user, I find a lot of stuff to be missing from the barebones vim installation, and therefore I went ahead and attempted to soup it up with plugins such as: rails.vim tcomment ruby-vim NERDtree and a couple of others. The issue is that I still don't quite get the average work-flow of using vim as one's Rails IDE. In RubyMine (again, similarly to Visual Studio) I have a series of tabs always open, containing the main files I'm switching among, and I additionally use NERDtree to open files from the folder structure. I tried opening them as new tabs, but the tab system in vim is just a lot more awkward than that in real IDEs. (I haven't seen vim pros in action, but I imagine that they'd not be relying on tabs, but using numerous splits instead, keeping at least a couple of files per split and switching between them with CTRL + ^. Is that the case?) So, at the end of the day, how do I really squeeze the most from vim if I want to be able to quickly access several files at once? Thank you!

• Finding the best practice for a game simulating tool

  - by Tougheart

  I'm studying Java right now, and I'm thinking of this tool as my practice project. The game is "League of Legends" in case anyone knows it, I'm not actually simulating the game as in simulating game play, I'm just trying to create a tool that can compare different champions to each other based on their own abilities and items bought inside the game. The game basics are: Every player has a champion in a team of 5 players playing against another team. Each champion has a different set of abilities (usually 4) that s/he uses to do damage to opposing champions. Each champion gets stronger by buying different items, increasing the attack it deals or decreasing the damage received. What I want to do is to create a tool to be used outside the game enabling players to try out different builds for their champions and compare the figures against other champions they usually fight against. The goal is to enable players get a deeper understanding of the different item combinations (builds) that can be used during the games, instead of trying them out in real games which can be somehow very time consuming. What I'm stuck at is the best practice I should follow to make this possible using Java, I can't figure out which classes should inherit from which, should I make champions and items specs in the code or extracted from other files, specially that I'm talking about hundreds of items and champions to use in that tool. I'm self studying Java, and I don't have much practice at it, so I would really appreciate any broad guidelines regarding this, and sorry if my question doesn't fit here, I tried to follow the rules. English isn't my native language, so I'm really sorry if I wasn't clear enough, I would be more than happy to explain anything that's not understood.

• How to unit test models in MVC / MVR app?

  - by BBnyc

  I'm building a node.js web app and am trying to do so for the first time in a test driven fashion. I'm using nodeunit for testing, which I find allows me to write tests quickly and painlessly. In this particular app, the heavy lifting primarily involves translating SQL data into complex Javascript object and serving them to the front-end via json. Likewise, the app also spends a great deal of code validating and translating complex, multidimensional Javascript objects it receives from the front-end into SQL rows. Hence I have used a fat model design for the app -- most of the real code resides in the models, where the data translation happens. What's the best approach to test such models with unit tests? I mean in particular the methods that have create javascript objects from the SQL rows and serve them to the front-end. Right now what I'm doing is making particular requests of my models with the unit tests and checking the returned data for all of the fields that should be there. However I have a suspicion that this is not the most robust kind of testing I could be doing. My current testing design also means I have to package my app code with some dummy data so that my tests can anticipate the kind of data that the app should be returning when tests run.

• Pipe an infinite stream to internal loop?

  - by Sh3ljohn

  I've seen a lot of things about redirecting stdout to a TCP socket, but no real example of how to do it in practice, specifically when the output stream generated by the first "command" never ends. To talk about something concrete, let's take programs like servers that typically output their log endlessly to stdout (well, as long as they run). If you redirect the output to a log file on the disk, then this file is always open (therefore not readable by others?) and grows infinitely, which eventually is going to cause problems. This might be a nood question, but I don't know what it does or how to do it so. How to redirect the output of a command to the internal loop? I want to make sure that data is sent EVERY time something is written to stdout, and that the pipe won't wait for the command to end (never happens ideally!). Is that right? If 2 is true, is there a buffer system to send chunks of data once it reaches a certain size only? Could you give me concrete command line examples to do the above? Thanks in advance

• In an online questionnaire, what is a best way to design a database for keeping track of users all attempts?

  - by user1990525

  We have a web app where users can take online exams. Exam admin will create a questionnaire. A questionnaire can have many Questions. Each question is a multiple choice question (MCQ). Lets say an admin creates a questionnaire with 10 questions. Users attempt those questions. Now, unlike real exams users can attempt single questionnaire multiple times. And we have to keep track of his all attempts. e.g. User_id Questionnaire_id question_id answer attempt_date attempt_no 1 1 1 a 1 June 2013 1 1 1 2 b 1 June 2013 1 1 1 1 c 2 June 2013 2 1 1 2 d 2 June 2013 2 Now it can also happen that after user has attempted same questionnare twice, admin can delete a question from same questionnaire, but users attempt history should still have reference to that so that user can see his that question in his attempt history in spite of admin deleting that question. If user now attempts this changed questionnaire he should see only 1 question. User_id Questionnaire_id question_id answer attempt_date attempt_no 1 1 1 a 3 June 2013 3 Also, after this user modified some part of question, users attempt history should show question before modification while any new attempt should show modified question. How do we manage this at the database level? My first gut feeling was that, For deletes, do not do physical delete, just make a question inactive so that history can still keep track of users attempt. For modifications, create versions for questions and each new attempt refres to latest version of each question and history keeping reference to version of question at attempt time.

• Material System

  - by Towelie

  I'm designing Material/Shader System (target API DX10+ and may be OpenGL3+, now only DX10). I know, there was a lot of topics about this, but i can't find what i need. I don't want to do some kind of compilation/parsing scripts in real-time. So there some artist-created material, written at some analog of CG. After it compiled to hlsl code and after to final shader. Also there are some hard-coded ConstantBuffers, like cbuffer EveryFrameChanging { float4x4 matView; float time; float delta; } And shader use shared constant buffers to get parameters. For each mesh in the scene, getting needs and what it can give (normals, binormals etc.) and finding corresponding permutation of shader or calculating missing parts. Also, during build calculating render states and the permutations or hash for this shader which later will be used for sorting or even giving the ID from 0 to ShaderCount w/o gaps to it for sorting. FinalShader have only 1 technique and one pass. After it for each Mesh setting some shader and it's good to render. some pseudo code SetConstantBuffer(ConstantBuffer::PerFrame); foreach (shader in FinalShaders) SetConstantBuffer(ConstantBuffer::PerShader, shader); SetRenderState(shader); foreach (mesh in shader.GetAllMeshes) SetConstantBuffer(ConstantBuffer::PerMesh, mesh); SetBuffers(mesh); Draw(); class FinalShader { public: UUID m_ID; RenderState m_RenderState; CBufferBindings m_BufferBindings; } But i have no idea how to create this CG language and do i really need it?

• Storing editable site content?

  - by hmp

  We have a Django-based website for which we wanted to make some of the content (text, and business logic such as pricing plans) easily editable in-house, and so we decided to store it outside the codebase. Usually the reason is one of the following: It's something that non-technical people want to edit. One example is copywriting for a website - the programmers prepare a template with text that defaults to "Lorem ipsum...", and the real content is inserted later to the database. It's something that we want to be able to change quickly, without the need to deploy new code (which we currently do twice a week). An example would be features currently available to the customers at different tiers of pricing. Instead of hardcoding these, we read them from database. The described solution is flexible but there are some reasons why I don't like it. Because the content has to be read from the database, there is a performance overhead. We mitigate that by using a caching scheme, but this also adds some complexity to the system. Developers who run the code locally see the system in a significantly different state compared to how it runs on production. Automated tests also exercise the system in a different state. Situations like testing new features on a staging server also get trickier - if the staging server doesn't have a recent copy of the database, it can be unexpectedly different from production. We could mitigate that by committing the new state to the repository occasionally (e.g. by adding data migrations), but it seems like a wrong approach. Is it? Any ideas how best to solve these problems? Is there a better approach for handling the content that I'm overlooking?

• can I achieve my dreams without a degree? [closed]

  - by Dhananjay

  It's really giving me a lot stress as my parents saying me to join college but I don't want. I know I can learn all programming by self studying but they keep saying join college otherwise no one will give you job. I always think positive but sometimes I also start thinking like them (what if my life will be spoiled if I do not go to college) There are so much things on internet. I can learn c++, objective c, java, AI, html, php all through internet (at least I think that I can learn whole by self studying and I can give 10 hour/day easily for studying) and I will keep practicing and become a good programmer in 2 years and then try to do some job for experience so no need to waste 4 years just for studying things which I can learn in 2 years and no need to waste money on college because they teach physics, chemistry all in first 2 years and I only want to study comp. Science. But now again I am thinking negative that what will happen if I do not get degree and what will I do after learning programming if I don't get job? Please suggest what should I do? Should I join college? or self study? Can I achieve my dreams without a degree if I study hard and learn many things? I have full confidence that I can self teach myself better than they will teach in college. I will open my app company and many more. But maybe I am over confident because I don't know what happens in real world. How they treat a person without degree, etc. Anyone of you had gone through this condition? What did you do?

• SQL to XML open data made simple

  - by drrwebber

  The perennial question for people is how to easily generate XML from SQL table content?  The latest CAM Editor release really tackles this head on by providing a powerful and simple toolset.  Firstly you can visually browse your SQL tables and then drag and drop from columns and tables into the XML structure editor.   This gives you a code-free method of describing the transformation you require.  So you do not need to know about the vagaries of XML and XSD schema syntax. Second you can map directly into existing industry domain XML exchange structures in the XML visual editor, again no need to wrestle with XSD schema, you have WYSIWYG visual control over what your output will look like. If you do not have a target XML structure and need to build one from scratch, then the CAM Editor makes this simple.  Switch the SQL viewer into designer mode, then take your existing SQL table and drag and drop it into the XML structure editor.  Automatically the XML wizard tool will take your SQL column names and definitions and create equivalent XML for you and insert the mappings. Simply save the structure template, and run the Open Data generator menu option, and your XML is built for you. Completely code-free template driven development. To see this in action, see our video demonstration links and then download the tools and samples and try it yourself.

• How can I make smoother upwards/downwards controls in pygame?

  - by Zolani13

  This is a loop I use to interpret key events in a python game. # Event Loop for event in pygame.event.get(): if event.type == QUIT: pygame.quit() sys.exit() if event.type == pygame.KEYDOWN: if event.key == pygame.K_a: my_speed = -10; if event.key == pygame.K_d: my_speed = 10; if event.type == pygame.KEYUP: if event.key == pygame.K_a: my_speed = 0; if event.key == pygame.K_d: my_speed = 0; The 'A' key represents up, while the 'D' key represents down. I use this loop within a larger drawing loop, that moves the sprite using this: Paddle1.rect.y += my_speed; I'm just making a simple pong game (as my first real code/non-gamemaker game) but there's a problem between moving upwards <= downwards. Essentially, if I hold a button upwards (or downwards), and then press downwards (or upwards), now holding both buttons, the direction will change, which is a good thing. But if I then release the upward button, then the sprite will stop. It won't continue in the direction of my second input. This kind of key pressing is actually common with WASD users, when changing directions quickly. Few people remember to let go of the first button before pressing the second. But my program doesn't accommodate the habit. I think I understand the reason, which is that when I let go of my first key, the KEYUP event still triggers, setting the speed to 0. I need to make sure that if a key is released, it only sets the speed to 0 if another key isn't being pressed. But the interpreter will only go through one event at a time, I think, so I can't check if a key has been pressed if it's only interpreting the commands for a released key. This is my dilemma. I want set the key controls so that a player doesn't have to press one button at a time to move upwards <= downwards, making it smoother. How can I do that?

• Influence Maps for Pathfinding?

  - by james

  I'm taking the plunge and am getting into game dev, it's been going well but I've got stuck on a problem. I have a maze that is 100x100 with 0,1 to indicate if its a path or a wall. Within the maze I have 300 or so enemies and a player. The outcome I'm looking for is all the enemies work their way towards the player position. Originally I did this using an A* path finding algorithm but with 300 enemies it was taking forever to path find each one individually. After some research I found that an influence map / collaborative diffusion would be the best way to go. But I'm having a real hard time working out how this is actually done. Firstly.. How do you create a influence map? From what I understand each of my walls with have a scent of 0 so that makes them impassable.. then basically a radial effect from my player position to each other cell (So my player starts at 100 and then going outwards from that each other cell will be reduced value) Is that correct? If so,.. How would you do that (Math magic?) My next problem is if that is correct how would my "enemies" stop from getting stuck if they have gone down the wrong way? As say if my player was standing on the otherside of a wall if the enemy is just looking for larger numbers wont it keep getting stuck? I'm doing this in JavaScript so performance is key. Thanks for any help! EDIT: Or if anyones got a better solution? I've been reading about navmeshs, steering pathing, pre calculating all paths on load etc etc

• Are specific types still necessary?

  - by MKO

  One thing that occurred to me the other day, are specific types still necessary or a legacy that is holding us back. What I mean is: do we really need short, int, long, bigint etc etc. I understand the reasoning, variables/objects are kept in memory, memory needs to be allocated and therefore we need to know how big a variable can be. But really, shouldn't a modern programming language be able to handle "adaptive types", ie, if something is only ever allocated in the shortint range it uses fewer bytes, and if something is suddenly allocated a very big number the memory is allocated accordinly for that particular instance. Float, real and double's are a bit trickier since the type depends on what precision you need. Strings should however be able to take upp less memory in many instances (in .Net) where mostly ascii is used buth strings always take up double the memory because of unicode encoding. One argument for specific types might be that it's part of the specification, ie for example a variable should not be able to be bigger than a certain value so we set it to shortint. But why not have type constraints instead? It would be much more flexible and powerful to be able to set permissible ranges and values on variables (and properties). I realize the immense problem in revamping the type architecture since it's so tightly integrated with underlying hardware and things like serialization might become tricky indeed. But from a programming perspective it should be great no?

• Password not working for sudo ("Authentication failure")

  - by Souta

  Before I mention anything further, DO NOT give me a response saying that terminal won't show password input. I'm AWARE of that. I'm typing my user password in (not a capslock issue), and for some reason it still says 'Authentication Failure'. Is there some other password (one I'm not aware of) I'm supposed to be using other than my user password? I've had this ubuntu before, on another hard drive and I didn't have this problem.

• Release Notes for 6/14/2012

  Here are the notes for this week’s release: Diffs in Pull Requests and Commits We altered the way we display diffs across commits and pull requests to maximize the amount of vertical real estate devoted to the diff. Before, the viewport for diffs was always snapped to the height of the browser, which meant that on lower resolutions, the amount of space for viewing diffs could become very tiny. Now, the majority of the browser vertical space is devoted to viewing the diffs. Let us know what you think! Bug Fixes Fixed an issue where returning to the list of files changed from a diff would sometimes not show the list of files. Fixed the dialogs for approving and denying requests to join projects. Fixed various issues around validation of project details when publishing a project. Fixed an issue that caused the formatting of our tabs in pull requests to not display properly. Fixed an issue where users browsing Unicode files in a Git project would see error pages. Fixed various issues where the option to subscribe to notifications would not appear properly.

• Do the benefits of Resin/Quercus outweigh the overhead?

  - by Craige

  Lately, I've been looking more and more into Resin + Quercus as a technology to develop an application of mine. The reason I started looking into it was that this application has high reporting needs, a lot of which cannot (or realistically, should not) be created in real-time. Java would offer a nice backend to queue and generate reports. Also, with Quercus I would be able to develop my data models in Hibernate, and use them "from PHP", thus effectively stretching these models across front and back-end. This same concept would also apply to any front/back-end common business logic, which could be developed in Java libraries. Now, the downside is that whichever front-end (PHP) MVC Framework I choose (my goal was Symfony 2), it is unlikely to work without some heavy modification, if it can work at all. Quercus is a pretty close implementation of PHP, and is supposed to be compatible with PHP5.3, so namespaces and closures SHOULDN'T be a problem, but when I tried to run an existing Symfony 1.4 app, I failed miserably. So, my question to you is, do you think the benefits of Resin + Quercus outweigh the overhead of using a not-so-perfect/stable implementation of PHP? If this were your application, and your goal was and end-product, rather than educational purposes, what would you decide?

• Making document storage in Sharepoint a breeze (leave the Web UI behind)

  - by deadlydog

  Hey everyone, I know many of us regularly use Sharepoint for document storage in order to make documents available to several people, have it version controlled, etc.  Doing this through the Web UI can be a real headache, especially when you have multiple documents you want to modify or upload, or when IE isn’t your default browser.  Luckily we can access the Sharepoint library like a regular network drive if we like. Open Sharepoint in Internet Explorer (other browsers don’t support the Open with Explorer functionality), navigate to wherever your documents are stored, choose the Library tab, and then click Open with Explorer. This will open the document storage in Explorer and you can interact with the documents just like they were on any other network drive J  This makes uploading large numbers of documents or directory structures super easy (a simple copy-paste), and modifying your files nice and easy. As an added bonus, you can drag and drop that location from the address bar in Explorer to the Favorites menu so that it’s always easily accessible and you can leave the Sharepoint Web UI behind completely for modifying your documents.  Just click on the new favorite to go straight to your documents.   You can even map this folder location as a network drive if you want to have it show up as another drive (e.g N: drive). I hope you found this as useful as I did

• Designing communications for extensibility

  - by Thomas S.

  I am working on the design stages of an application that will a) collect data from various sources (in my case that's scientific data from serial ports), keeping track of the age of the data, b) generate real-time statistics (e.g. running averages) c) display, record, and otherwise handle the data (and statistics). I anticipate that I will be adding both data producers and consumers over time, and would like to design this application abstractly so that I will be able to trivially add functionality with a small amount of interface code. What I'm stumbling on is deciding what communication infrastructure I should use to handle the interfaces. In particular, how should I make the processed data and statistics available to multiple consumers? Some things I've considered: Writing to several named pipes (variable number). Each consumer reads from one of them. Using FUSE to make a userspace filesystem where a read() returns the latest line of data even if another process has already read it. Making a TCP server, and having consumers connect and request data individually. Simply writing the consumers as part of the same program that aggregates the data. So I would like to hear your all's advice on deciding how to interface these functions in the best way to keep them separate and allow room for extenstions.

• More NASM with GVim

  - by MarkPearl

  Today I am bashing around with nasm again… some useful things I found… Set the current working directory of gvim to the current file path I have found setting the current working directory of gvim to the file location is very useful, especially if you are wanting to use commands in gvim to run your compiled code. It can be done by typing in the following in the command mode in gvim… cd %:p:h Once you have set it, you can use the ! to run commands you would normally run in the dos shell.. e.g. !dir Compiling code to make an executable There are three thing you need to specify to compile a basic file in name, they are… The output file format The output file name The source file name An example of this would be the following (where you have a file called temp.asm which is the source file) nasm –f bin temp.asm –o temp.com Output file format The –f specifies the output file format (in this case a binary file). To get a list of the available output file formats you can type nasm –hf (for my installation bin is the default, in which case I can omit it) Output file name This is just the name you want the compiled file to be called. For windows machines I specify .com as my default format.
