• What's the proper way of importing option lists into an Android app?

  - by Scott

  I have been storing option lists for my Android app in a cloud table. For example, categories like "historical fiction","biography","science fiction", etc. I see the following pros and cons: Pro: I can make changes to the list without sending an app update to Google Play Not normalized - I can use the text in my other data tables instead of a reference ID Con: App needs to take time to download from the web each time (or at least check for changes) English only I believe the "proper" way to do this is the use the XML resource files. But I need to make sure the selection references correctly with my data. That is, my app needs to understand that "Poetry" and "Poesía" are the same thing. Is the correct thing to do: Forget about it since I'll never get to the point where I'm translating my app anyway Use a string-array and use the index (0...x) to know what the selection is Use a 2-dimensional string-array with a reference ID in the first column and the text in the second?

• Proguard shrinks too much

  - by vRallev

  Since ADT 17 you can find in the gen folder a BuildConfig class with a DEBUG constant. I often use this constant in my code, since ADT changes the value automatically when you export the application. However with Proguard this doesn't work anymore. E.g. I have following snippet: if (!BuildConfig.DEBUG) { ACRA.init(this); } Proguard notices, that DEBUG is true, so it removes this snippet completely and shrinks the app. After that ADT changes DEBUG constant, but this is too late. The only solution I know is to create my own DEBUG constant and to change it manually again. But I really like the functionality of ADT. Do you know a better solution? Thanks in advance.

• What is the best way to add attributes to auto-generated entities (using VS2010 and EF4)

  - by Dani

  ASP.NET MVC2 has strong support for using attributes on entities (validation, and extending Html helper class and more). If I generated my Model from the Database using VS2010 EF4 Entity Data Model (edmx and it's cs class), And I want to add attributes on some of the entities. what would be the best practice ? how should I cope with updating the model (adding more fields / tables to the database and merging them into the edmx) - will it keep my attributes or generate a new cs file erasing everything ? (Manual changes to this file may cause unexpected behavior in your application.) (Manual changes to this file will be overwritten if the code is regenerated.)

• Advice and resources on collaborative environments

  - by Tjaart

  I need some advice on collaborative software environments. More specifically, I am looking for books and reference materials that can aid me in understanding team and code structures and the interactions thereof. In other words books, blogs or white papers explaining: Different strategies for structuring teams that share common code between each other but have distinct individual functions? To summarise my question I would like to know what would be a good source of knowledge if I were to set up teams in an organisation that shared code but each unit still remained autonomous. I have done some research on this subject and explored: code review tools, distributed VCS, continuous integration tools, Unit testing automation. The tough part about implementing these tools are to determine where a good place would be to start, which tools are low hanging fruit, which tools or methods provide higher success rates. If someone asks me about code quality reference I point them to Code Complete. I am looking for an equivalent guide on software team structures and tools to make this equation work better. I realise that this question is quite vague but it arose as "we need to share code between teams without breaking each others stuff and causing management headaches and reams of red tape" The answer is definitely not simple and requires changes on many levels, hence the question. If the question is too vague please vote to close or delete. I would accept any good starting point as an answer.

• EF 4.1 Code First Detaching Entity

  - by Nazaf

  I am trying to add an entity to the DB. Once I have added it, I want to detach it, so I can manipulate the object safely without making any changes to the DB. After calling context.SaveChanges() I do the following to detach the entity: // save context.Stories.Add(story); // attach tags. They already exists in the database foreach(var tag in story.Tags) context.Entry(tag).State = System.Data.EntityState.Unchanged; context.SaveChanges(); context.Entry(story).State = System.Data.EntityState.Detached; However, changing the entity state to DETACHED will remove all related entities associated with the my entity. Is there a way to stop this ? If I don't detach the entity, all my changes are sent to the DB next time I call context.SaveChanges() Thanks!!

• I had inserted a jQuery tab in my site. It was working fine till sometime ago. Suddenly it stopped w

  - by vr3690

  Hello, I had inserted two jQuery tabs on my site. One div container had the id - tabs and another had the id tabs-for-views. Both of them were working fine till sometime ago, until i made some changes. I don't remember what the exact changes were.. Right now, the first tab uses the jQuery UI theme I am using. As in, I can see the tab navigation and content panels - but on clicking the tabs nothing happens. But the second (tabs-for-views) is not even converted to proper tabs format. I am using the Drupal CMS for this site. the tabs can be found on this page: http://betterclassofleaders.co.cc/whackk/ this is the jquery ui css file i am using: (insert first link)sites/default/themes/whack_custom/jquery-ui-1.7.2.custom.css

• HTML Input on change of value

  - by arik-so

  Hello, I have an input tag. This tag does not have the autocomplete feature turned off, thus, one does not necessarily need to release a key to change the value of this field and focus anotehr one. My question is: how can I detect ANY value changes of this particular field, like e. g. <input onvaluechange="//do following..." /> The JavaScritp attribute onchange does not fire on change of value, only on changes like blur, focus, etc... Thanks in advance!

• Does anyone have an updated version of the SQLite .NET assembly, ie. SQLite 3.6.23.1 + possibly .NET

  - by Lasse V. Karlsen

  I'm at my wits end with the best .NET assembly version of SQLite, the one found at http://sqlite.phxsoftware.com. The only maintainer doesn't seem to have the time to update the library and it generally takes months, if not more, for newer versions to surface. Luckily, he has published the source code, so I'm hoping that someone else has made his/her own copy of it, and made the changes, and would be willing to share a copy. I've seen comments on the forums for the library to this effect, but sadly even the forum software seems to be grinding to a halt these days as password reminder emails seems to be lost to the big void, so I can't ask the few there that has said they have done it. So I'm here, hopefully the big userbase of StackOverflow can help. What I'm looking for: Updated with the latest changes to SQLite, ie. SQLite version 3.6.23.1 Possibly built for .NET 4.0 (I can do that if I can get a copy of working source) Does anyone have, or know of anyone, that has done this?

• Automatically "upgrade" user settings from previous version of app.config file?

  - by SqlRyan

  Every time I compile my app and the version number changes (I have an auto-incrementing build number), I lose the user-configured app.config settings, since they're stored in the AppData folder for a specific version. Essentially, every release of my application starts from scratch as far as user settings go. While this is a mild annoyance in development, it raises the question as I approach deployment/release - if I use the app.config to store my user settings, will the user's personalized settings be hosed every time they install a patch that changes the version number of my app? If so, is there an easy way to "upgrade" the settings from the previous release? I know that using HKCU in the registry is another option, but I like the ease of the My.Settings namespace, and I'd like to stay with app.config. Another SO question asks something similar, though the answer doesn't seem that clear. Will setting my MSI so it asks the user to upgrade be enough to preserve these user-level settings?

• Displaying change of content through parent

  - by Mikhail

  I have DHTML content inside a fieldset. This includes plain html, nested objects (even other fieldsets), and value change of input, select, and textarea objects. I'd like to change the border of the fieldset if the contents have been changed. The following works: $('fieldset[name=qsfs127]').children('input').change(function(){ $(this).parent('fieldset').css({border:'1px solid red'}); }) This handles the input; I can extend it to select and textarea. Questions: How can I do the same for html changes? Can all of this change-tracking be done by comparing current html() to stored one? If yes for (2), will this handle cases of "undo"? Edit: I have a button that ajax-uploads contents, and saves the changes. I then remove the border color

• Can I have a workspace that is both a git workspace and a svn workspace?

  - by Troy

  I have checked out now a local working copy of a codebase that lives in an svn repo. It's a big Java project that I use Eclipse to develop in. Eclipse of course builds everything on the fly, in it's own way with all the binaries ending up in [project root]/bin. That's perfectly fine with me, for development, but when the build runs on the build server, it looks quite a lot different (maven build, binaries end up in a different directory structure, etc). Sometimes I need to recreate the build server environment on my local development system to debug the build or what have you, so I usually end up downloading an entirely new working copy into a new workspace and running the build from there (prevents cluttering my development workspace with all the build artifacts and dirtying up the working copy). Of course sometimes I'm interested in running the full build on code that I don't want to check in yet, so I will manually copy over the "development" workspace onto the "build" workspace. Besides taking a lot of extra time copying a lot of files that I don't actually need (just overlaying the new over the old), this also screws up my svn metadata, meaning that I can't check in changes from that "build workspace" working copy, and I often end up having to re-download the code to get it back into a known state. So I'm thinking I make my svn working copy a local git repo, then "check out" the in-development code from the svn working copy/git master, into the local build workspace. Then I can build, revert my changes, have all the advantages of a version controlled working copy in the build workspace. Then if I need to make changes to the build, push those back into the git master (which is also a svn working copy), then check them into the main svn repo. |-------------| |main svn repo| <------- |---------------------| |-------------| |svn working copy | <------- |--------------------| | (svn dev workspace/ | | non-svn-versioned | | git master) | | build workspace | |---------------------| | (git working copy) | |--------------------| Just switching everything to git would obviously be better, but, big company, too many people using svn, too costly to change everything, etc. We're stuck with svn as the main repo for now. BTW, I know there is a maven plugin for Eclipse and everything, I'm mainly interested to know if there is a way to maintain a workspace that is both a git working copy and an svn working copy. Actually any distributed version control system would probably work (hg possibly?). Advice? How does everybody else handle this situation of having a to manage both a "development" build process and a "production" build process?

• database modeling for google app engine for multiple revison of entity.

  - by iamgopal

  hi, in my application ( kind of wiki clone ) - an article is frequently changing. and i need to track all changes that are done on that article. { text only. } one crude way i have done it, is to add a datetime property and create a new entity everytime something change. which is too much database wasting. { and also un-necessary index waste too. } and also need to re-create parent-child and entity relationships. i also have log which can show changes -- but i want some thing easier , so that jumping from one version to another version could be easier. ideas ? thanks.

• Database Schema Versioning Strategies

  - by Jack Ryan

  I work on a project that uses a reasonably large database, the live version weighing in at somewhere around 60-80GB. The live database is the only real definitive source of our schema, and because of its size duplicating this database is too slow to be done often. This means we have ended up developing our database schema in a pretty ad hoc way, using sql compare to migrate changes from dev dbs to the live system, and only wiping our dev dbs every month or two. I am hoping to get some pointers on how to improve our database development work flow so that we have a little more control. Some things to think about: Currently nobody is really in charge of the database schema, all developers can change it if they need to, though generally these decisions are talked about before they are done. There are stored procedures, functions, and views in the database. These should probably be dumped to files so they can be reloaded on every build. Schema changes should probably be checked in as scripts. We have started to do this recently. However all our scripts must then be numbered (because there may be dependencies between them), and must be re runnable (because our build script currently runs them all in order). This makes them hard to read because they are full of conditionals that check whether tables or columns already exist. This is a step that is often forgotten by developers. Getting a new database should be quick and easy. This is currently a big problem, it takes several hours to get a copy of last nights backup and restore it onto a dev machine. Some mechanism needs to be in place to allow developers to update static data. We have tables that contain data that is never updated through the application, but does potentially need to be changed when we do a new release (often this drives dropdowns). The whole thing needs to be runnable as part of a build script. Are there any tools that can be used to help to do this? Eventually I would like to be at a point where a new DB can be built from scratch without copying any data from the live system. I don't mind writing some scripts to glue all the steps together but each part should be easily editable so that we continue to use it rather than make changes directly on DBs.

• rsync useful w/ encrypted files?

  - by barrycarter

  Is rsync efficient for transferring encrypted files? More specifically: I encrypt 'x' with my public key and call the result 'y'. I rsync 'y' to my backup server. 'x' changes slightly I encrypt the modified 'x' and rsync the modified 'y' to my backup server. Is this efficient? I know a small change in 'x' yields a large change in 'y', but is the change localized? Or has 'y' changed so thoroughly that rsync is not much better than scp? I currently backup my "critical" files by tarring/bzipping them nightly, then encrypting the .tar.bz file and rsync'ing it to my backup server. Many of the individual files don't change, but, of course, the tar file changes if even one of the files change. Is this efficient? Should I be encrypting and backing up each file individually? That way, unchanged files will take no time to rsync.

• GIT Clones on Multiple Machines

  - by Adam

  Here's my setup... Laptop (Mac) - git clone of svn repository Thumb drive - git clone of laptop git repository Server (Win Server 08) - git clone of thumb drive repository I'm having trouble keeping them in sync for some reason... If I make a change on the server, I'll do a "git pull " on the thumb drive to get the changes. Take the thumb drive to the laptop and do "git pull " on the laptop. From there, I can do "git svn dcommit" and everything goes up to the SVN repo with no problem. If I pull changes from SVN with "git svn rebase" and then do a pull onto the thumb drive and do a "git status" it says that I'm ## revisions ahead of the master/origin and I can't figure out why.

• How to make schema and code dynamic?

  - by Jonarch

  I want to make my database schema and application code as dynamic as possible to handle "unknown" use cases and changes. Developing in PHP and MySQL. Twice now I have had to change my entire schema including table and column names and this means the developers have to go back to the application code and modify all the SQL queries and table/columns names. So to prevent this I want to if just like we do on pages where we have page content, title bar etc dynamic like a %variable%, can we do it for the schema and maybe even for the php code functions and classes somehow? It takes weeks to re-do all changes like this vs if it is dynamic it can be done in under a day.

• Python OpenGL Can't Redraw Scene

  - by RobbR

  I'm getting started with OpenGL and shaders using GLUT and PyOpenGL. I can draw a basic scene but for some reason I can't get it to update. E.g. any changes I make during idle(), display(), or reshape() are not reflected. Here are the methods: def display(self): glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT ) glMatrixMode(GL_MODELVIEW) glLoadIdentity() glUseProgram(self.shader_program) self.m_vbo.bind() glEnableClientState( GL_VERTEX_ARRAY ) glVertexPointerf(self.m_vbo) glDrawArrays(GL_TRIANGLES, 0, len(self.m_vbo)) glutSwapBuffers() glutReportErrors() def idle(self): test_change += .1 self.m_vbo = vbo.VBO( array([ [ test_change, 1, 0 ], # triangle [ -1,-1, 0 ], [ 1,-1, 0 ], [ 2,-1, 0 ], # square [ 4,-1, 0 ], [ 4, 1, 0 ], [ 2,-1, 0 ], [ 4, 1, 0 ], [ 2, 1, 0 ], ],'f') ) glutPostRedisplay() def begin(self): glutInit() glutInitWindowSize(400, 400) glutCreateWindow("Simple OpenGL") glutInitDisplayMode(GLUT_SINGLE | GLUT_RGB) glutDisplayFunc(self.display) glutReshapeFunc(self.reshape) glutMouseFunc(self.mouse) glutMotionFunc(self.motion) glutIdleFunc(self.idle) self.define_shaders() glutMainLoop() I'd like to implement a time step in idle() but even basic changes to the vertices or tranlastions and rotations on the MODELVIEW matrix don't display. It just puts up the initial state and does not update. Am I missing something?

• How do I get a UIView which displays text to behave like a UILabel when bounds change?

  - by Hilton Campbell

  I have a UIView in which I need to draw text in drawRect: - (void)drawRect:(CGRect)rect { ... [@"some text" drawAtPoint:somePoint withFont:someFont]; ... } Because the text requires special formatting, I cannot just use a UILabel. It looks fine until I rotate the device. Then the size of my custom UIView changes (in the parent view's layoutSubviews method), and the text becomes stretched in one direction and squished in the other. When I replace my view with a UILabel, the text always looks great, even when the bounds of the view changes. How can I get my view to exhibit the same behavior as UILabel? Some things I have looked into, but have yet to have success with: Set the view's layer's needsDisplayOnBoundsChange to YES. Set the view's contentStretch to CGRectZero. Call setNeedsDisplay in my view's layoutSubviews. Maybe I'm not doing one of these things right. Has anyone else run into this?

• Indexing Bilingual Sites

  - by Affar

  Hi all I have a site that supports two languages. The way the user changes the language is by clicking on a language link that will change his session language from A to B and return him to the same page. The problem that I am facing is that Google doesn't index the other language since it is seeing that the language link is the same as the page link but with changes in the parameters. So is there a way to inform google of the language, or should I add the language in the url, i.e. www.example.com/A/home?

• Facebook contest policy no-no?

  - by Fred

  I would like to post a link on a Facebook page where it will exit Facebook entirely and go to a client's website, where people will be on a page (client's) where they can enter their e-mail address to be entered in a temporary database file with rules and disclosures etc., for a draw once the number of entries reaches 100 for instance. Once the number of entries reaches 100, a random winner is picked and notified via E-mail. The functionality is as follows: A link is place on a Facebook page leading to an external page The page is a form to merely enter their email address for a contest The email is placed in a temporary file An automatic E-mail is sent to the address used for confirmation using SHAH-256 hash The person receives the Email saying something to the affect "Please confirm your Email address etc. - If you did not authorize this, simply ignore this message and no further action will be taken". If the person clicks on the confirmation link, the Email is then stored in the database and the person is again notified saying "Thank you for signing up etc." Once others do the same process and the database reaches a certain number, the form is no longer accessible and automatically picks a random Email. Once picked, an Email is automatically sent to the winner stating the instructions, and notifying me also. Once that person clicks yet another confirmation link, the database is then automatically deleted. I have built this myself and have no intentions of breaking any rules, nor jeopardize the work/time/energy I have put into this project. Is this allowed?
