  • "Send it to a friend" button on a webpage

    - by kender
    Hey, How often do we see stuff like "Send this page to a friend" on a webpages? Well, I see them quite often. My question is, how do you guys see it's effectiveness? If I hit a webpage that's interesting, and I think my friend would enjoy it, I can just copy the URL from my browser bar, paste it into the email and press "Send" button. In my opinion, it's usually faster and less mistake-aware then the button/link like this on the webpage. In addition, I'm not really sure what this website does with the emails I enter there - don't they store it and then sell for $1/100 addresses to spammers? My question is - when you design a website, do you put such links on the pages (it's often seen on sites with some news/articles)? Does it even make sense?

  • Android: implementing sliding cards in widget

    - by DroidIn.net
    I have a widget that periodically updates itself (hourly) to display top result of search query. I would like to extend it so it captures several top results and then loops through these. The best example would be Genie News and Weather widget for which I was unable to find a source code. QUESTIONS: What would be a good way to implement the animation? I'm thinking ViewAnimator + timer, but is there maybe a better way, say FrameLayout + alerts? I'm already using AlertManager to periodically pull search results for the widget How bad such arraignment would affect phone's battery life?

  • Is it best to code from a blank sheet or improving a code that's already written?

    - by user300371
    Just had a curious thought, but for general coding and programming, do you think it's best to work out all the logic yourself and start from a blank sheet or just take a code that has been written already(by you or someone else) and just change it to your liking? Assuming you have a programming background of like 1year+. (because as a beginner, it's best to learn from nothing) I'm not saying copy+paste someone else's code and say it's yours.

  • iPad --- managedObject problem when [self.tableViewSection reloadData]

    - by user345777
    Hi , I am creating a news aggregator application that fetches a xml feed every 4 minutes. After the xml is loaded, I clear everything by deleting all the objects in the database, then save the new objects back into the database. I then call [self.tableViewSection reloadData]; to reload the tableView. Thats when I get a problem. As soon as the code gets to a section where i access the new [[managedObject valueForKey:@"event_text"] description] content it fails with a : * Terminating app due to uncaught exception 'NSObjectInaccessibleException', reason: 'CoreData could not fulfill a fault for '0x4b3f6a0 '' Now from the flow I described on top, it seems odd to me that the tableView is populated properly the next time i launch the application, with the "new" data I fetched in the previous session. So its not that data thats corrupt , but seems to me something goes wrong when I refetch the managedObject after saving new data. Also keep in mind thats this app runs fine on the iPhone, its the iPad thats is giving me this problem.

  • Rails: Serializing objects in a database?

    - by keruilin
    I'm looking for some general guidance on serializing objects in a database. What are serialized objects? What are some best-practice scenarios for serializing objects in a DB? What attributes do you use when creating the column in the DB so you can use a serialized object? How to save a serialized object? And how to access the serialized object and its attributes? (Using hashes?)

  • Ensuring uniqueness on a varchar greater than 255 in MYSQL/InnoDB

    - by Vijay Boyapati
    I have a table which contains HTML entries for news pages. When I initially designed it I used URL as the primary key. I've learned the error of my ways because left-joining is super slow. So I want to redesign the table with an integer (id) primary key, but still keep the rows unique based on the URL. The problem is that I've found URLs longer than 255 characters, and MySQL isn't letting my create a key on the URL. I'm using an InnoDB/UTF8 table. From what I understand it's using multiple bytes per character with a limit of 766 bytes for the key (in InnoDB). I would really love suggestions on an elegant way of keeping the rows unique based on URL, while using an integer primary key. Thanks!

  • International Zip Code Search

    - by Dave
    I implemented a U.S. "find near zip code" search for somebody. The coordinates of U.S. zip codes come from a commercial zip code database. Now, they would like a similar ability for countries other than the U.S. Has anybody implemented something like this for non-U.S. searches? How about general "find close to this address" searches? What commercial data is available?

  • Delphi: Which are the downsides of having unused units listed in the uses clause?

    - by user193655
    I use cnPack Uses cleaner, but in general which are the downsides of having useless units? I know some of them: 1) of course if the unit is never used across the full project there will be useless resource consuption 2) the code insight will give useless results 3) the code insight will be slower But imagine a simple case: I have a project with 2 forms, I use StrUtils in one of them but I declared StrUtils in both of them... Is there any downside in temrs of memory consumption in this case or not?

  • REST services - exposing non-data "actions"

    - by ctacke
    I understand how to use REST for doing general entity interactions - using urls names to map to entities and the HTTP verbs to map to actions on those entities. But what is the generally accepted way of looking at "actions" more like RPC? For example, let's say I want to send a command for the device to reset? There's no real "entity" here or do I do something like POST to http://mydevice/device/reset?

  • Database advantages? Access, MySQL, msSQL, or any others?

    - by JimZ
    Dear all Stackoverflowers, I just started to learn programming and now I'm putting this question online based on a quote: no question is silly My work needs to develop a order system based on web, which wants a database system. Since using Excel for years as a general office user, I naturally turn this to Access. However, most people say Access is very limited comparing to MySQL or MSSQL, or any other more professional database system. But after developing some functions for my company's order system, I really find Access can fulfill my request. And I also tried MSSQL to develop, which I found it not quite convenient to use. I have searched in stackoverflow and find no general answer about my doubt. Now I am sincerely hoping some experienced and professional developers could clear my doubts. Now I'm listing some Access advantages, which I don't think other database system have. I hope you could help me also find these advantages in others. 1. Access is portable, I can just copy a xxx.accdb file to my company and continue with development. 2. Access is easy to generate helpful table, for example, it will automatically generate a field that can automatically count, could be used as primary key value. 3. it is more compatable with Excel, to display and filter data. 4. importantly, it nerely needs no environment to setup, just needs MS Office to be installed. ............others However, I also find some points that MSSQL is advantaged: 1. security reasons 2. easy to backup, ( just use BACKUP..... sql statement to do it) 3. can edit stored procedure to save some functions to database ...............others specifically, I wish some friends could tell me how to make other database portable? since I usually work both at home and in office. It's a headache to move MSSQL work to my office, since the version of MSSQL is not the same. Thank you all and best regards, :)

  • CMS or roll-yer-own?

    - by girlwithglasses
    I have a database of software tools and I want to be able to have users rate and comment on the tools, and view the ratings and comments that other users have left. To lower the risk of spammers attacking the site, I would like to be able to restrict comment/rating permissions to those who are logged in. At present, the tools are in a list on a static html page as part of a website that is very "non-interactive"; other than the contact form, there is nowhere that users contribute content to the site. We maintain a wiki (of the standard mediawiki flavour) that users can contribute to, and we also have a Drupal installation as a news site. Does anyone have any experience of creating such a rating/commenting system, and whether it would be better to use Mediawiki or Drupal (or another free CMS?), or to try to create something myself? Any advice would be appreciated. Thanks!

  • Possible ways of representing data in memory (.net)

    - by This is it
    Hi What are the possible ways of representing data in memory in .Net (or in general)? It would be great if data could be sorted and looked up by key (or multiple keys). We are thinking to use collections, arrays, list of collections/arrays. One object would be in several collections (one sorted asc, other desc, etc.). Maybe this is not a good idea, and we would like to hear some other possible solutions. Thank you

  • "Multi-threading" w/ NSTimers in an iPhone app

    - by MrDatabase
    Say I have two NSTimers in my iPhone app: timer1 and timer2. timer1 calls function1 30 times per second and timer2 calls function2 30 times per second. Assume these two functions are reading and updating the same integer variables. Are there any "multi-threading" issues here? If not how does iPhone OS handle the execution of the two functions (in general)?

  • Can you automate the new product registration in iTunes Connect (In App Purchase) ?

    - by Luc
    I am considering using In App Purchase for our iPhone app. But since we will offer a larger quantity of content items (10 video items each day added), I would like to automate the new product registration in iTunes Connect. Is this possible ? If not: how long does it typically take before Apple approves a new registred product in iTunes Connect ? Since the content looses quickly it's 'freshness' (news broadcasts...), it is crucial to be able to have new content available ASAP. Would you recommend using In App Purchase for this scenario or would you recommend developing our own payment & account system ?

  • Validating entered user data

    - by msfanboy
    Hello, this is a general question but I do a desktop application. Should I check for example the firstname exceeding 50 chars or is this a matter of taste? Or should I check for 50 chars because the user could flood my database with 10000000 chars ?
