• Learning Spring MVC For web-projects

  - by John

  I have looked at Spring MVC a few times briefly, and got the basic ideas. However whenever I look closely it seems to require you already know a whole load of 'core Spring'. The book I have for instance has a few hundred pages before it gets onto Spring MVC... which seems a lot to wade through. I'm used to being able to jump in, but there's so much bean-related stuff and XML, it just looks like a mass of data to consume. Does it simplify if you put the time in, or is Spring just a much bigger framework than I thought? is it possible to learn this side of it in isolation?

• can I auto update my uitextview from the value of the row of my uipickerview without pressing any se

  - by Wesley

  So I have a uipicker view, that I have managed to load some data from my db into. I would like to update a textview, which is right above the pickerview, with each changing of the row. Is that possible? If I don't have to, I would like to avoid pushing a button in order to show the respective text. Can I make it so that the value in the text field changes with the value of the rowselected in the pickerview, in real time? Any thoughts or code snippets would be appreciated. Thanks!

• What tech stack/platform to use for a project?

  - by danny z

  Hey guys, This is a bit of a weird meta-programming question, but I've realized that my new project doesn't need a full MVC framework, and being a rails guy, I'm not sure what to use now. To give you a gist of the necessary functionality; this website will display static pages, but users will be able to log in and 'edit their current plans'. All purchasing and credit card editing is being handled by a recurring payment subscriber, I just need a page to edit their current plan. All of that will be done through (dynamic) XML API calls, so no database is necessary. Should I stick with my typical rails/nginx stack, or is there something I could use that would lighten the load, since I don't need the Rails heft. I'm familiar with python and PHP but would prefer not to go that route. Is Sinatra a good choice here? tl;dr: What's a good way to quickly serve mostly static pages, preferably in Ruby, with some pages requiring dynamic XML rendering?

• Are there plans to make a non-programming general version of StackOverFlow like Yahoo Answer! [close

  - by RoboShop

  Firstly, I would like to say I think StackOverflow is a really great website, not just from a content perspective, but from a design perspective. The UI is designed in a way that makes it easy to use and the points are great incentives to be a productive part of the community. I was wondering, is there a part of the site, or maybe is there plans to make a new site, which is not programming driven. Like a general knowledge site but with StackOverflow as the engine. I use sites like Yahoo Answer! and they can be useful. But I think the main difference between Stack Overflow and Yahoo Answer is that Yahoo Answer encourages content indiscriminately, whereas Stack Overflow is disciplined enough that it only encourages content that are helpful or useful. I find it great that I can load up a question and the best answer pops up immediately, and the bad answers are voted down. Thanks

• Rails Asset Caching Breaks First few page loads

  - by Brian Armstrong

  We're using Rails asset caching for JS and CSS like this: <%= javascript_include_tag :defaults, 'autocomplete', 'searchbox', 'jqmodal', :cache => set_asset_cache(:admins) %> In our deploy we call rake tmp:assets:clear each time. The problem is that the first few page loads after a deploy come up with no css on the page. I guess until the cached all.js and all.css have been regenerated. We deploy many times per day and this is scary for any users who happen to come across a busted page. Have people found any way to make this smoother so the new cached assets are guaranteed to be there on the first new page load?

• Using JS to POST a form in an iframe.

  - by Stavros Korokithakis

  I would like to POST a form in an iframe, generated like so: My JS loads an iframe inside the page, adds a form to the iframe and submits the form. What I would like to happen is the iframe to load the result of that request. So, I would effectively like to post a form and render the result inside the iframe, without touching the parent (apart from putting the iframe up for display in the first place). I am using the code from this answer: http://stackoverflow.com/questions/133925/javascript-post-request-like-a-form-submit/134003#134003 but I can't get it to not reload the parent. I post the form, and instead of the iframe refreshing, the entire parent refreshes. I don't know why that is, since the url it's posting to is different and would at least redirect there. Can anyone help me with this problem? I just want a post inside an iframe and only within the iframe, basically.

• Single SignOn - Best practice

  - by halfdan

  Hi Guys, I need to build a scalable single sign-on mechanism for multiple sites. Scenario: Central web application to register/manage account (Server in Europe) Several web applications that need to authenticate against my user database (Servers in US/Europe/Pacific region) I am using MySQL as database backend. The options I came up with are either replicating the user database across all servers (data security?) or allowing the servers to directly connect to my MySQL instance by explicitly allowing connections from their IPs in my.cnf (high load? single point of failure?). What would be the best way to provide a scalable and low-latency single sign-on for all web applications? In terms of data security would it be a good idea to replicate the user database across all web applications? Note: All web applications provide an API which users can use to embed widgets into their own websites. These widgets work through a token auth mechanism which will again need to authenticate against my user database.

• Limit the number of cron jobs runnging a PHP script

  - by ed209

  I have a daily cron job that grabs 10 users at a time and does a bunch of stuff with them. There are 1000's of users that are part of that process every day. I don't want the cron jobs to overlap as they are heavy on server load. They call stuff from various APIs so I have timeouts and slow data fetching to contend with. I've tried using a flag to mark a cron job as running, but it's not reliable enough as some PHP scripts may time out or fail in various ways. Is there a good way to stop a cron job from calling the PHP script multiple times, or controlling the number of times it is called, so there are only 3 instances for example? I'd prefer a solution in the PHP if possible. Any ideas? At the moment I'm storing the flag as a value in a database, is using a lock type file any better as in here http://stackoverflow.com/questions/851872/does-a-cron-job-kill-last-cron-execution ?

• Migrate a Django project from MySQL to Oracle

  - by pablo

  Hi, I have a Django1.1 project that works with a legacy MySQL db. I'm trying to migrate this project to Oracle (xe and 11g). We have two options for the migration: - Use SQL developer to create a migration sql script. - Use Django fixtures. The schema created with the sql script from sql developer doesn't match the schema created from syncdb. For example, Django expects TIMESTAMP columns while sql developer creates DATE columns. Using syncdb with Django fixtures could be great but when trying to load the MySQL fixtures into Oracle, after using syncdb, I'm getting: IntegrityError: ORA-00001: unique constraint (USER.SYS_C004253) violated How can I find what part create the integrity error? Thanks

• Major performance difference between two Oracle database instances

  - by jrdioko

  I am working with two instances of an Oracle database, call them one and two. two is running on better hardware (hard disk, memory, CPU) than one, and two is one minor version behind one in terms of Oracle version (both are 11g). Both have the exact same table table_name with exactly the same indexes defined. I load 500,000 identical rows into table_name on both instances. I then run, on both instances: delete from table_name; This command takes 30 seconds to complete on one and 40 minutes to complete on two. Doing INSERTs and UPDATEs on the two tables has similar performance differences. Does anyone have any suggestions on what could have such a drastic impact on performance between the two databases?

• Loading a XML, but for asp.net 2.0

  - by Blankman

  I need to load an XML document into my Dictionary<string,string> object. XML looks like: <nodes> <node id="123"> <text>text goes here</text> </node> </nodes> How can I do this using XmlDocument? I want readability over performance, and I find XmlReader to be hard to read b/c you have to keep checking the node type.

• Distributed, persistent cache using EHCache

  - by Richard

  I currently have a distributed cache using EHCache via RMI that works just fine. I was wondering if you can include persistence with the caches to create a distributed, persistent cache. Alongside this, if the cache was persistent, would it load from the file store, then bootstrap from the cache cluster? Basically, what I want is: Cache starts Cache loads persistent objects from the file store Cache joins the distruted cluster and bootstraps as normal The usecase behind this is having 2 identical components running on independent machines, distributing the cache to avoid losing data in the event that one of the components fails. The persistence would guard against losing all data on the rare occasion that both components fail. Would moving to another distribution method (such as Terracotta) support this?

• Best way to do partial update content on ASP.NET

  - by kevin

  Initially i was planning to use master page for every page in my application. At the end, i found out every times the page is changed, it reload full page even it have the same master page. I have confused the frameset with the master page. Then, i have 2 ideas in my minds to achieve it by not using master page. Using iframe and set the attribute to runat server, so that i can change the page in my codebehind.(I preferred to control the page flow in server side) Make every single child page to user control. Then dynamically load it to the panel in codebehind. Please give me some advise which method is the best in ASP.NET with AJAX enabled, or other ways that is better. Thanks.

• Pig: Count number of keys in a map

  - by Donald Miner

  I'd like to count the number of keys in a map in Pig. I could write a UDF to do this, but I was hoping there would be an easier way. data = LOAD 'hbase://MARS1' USING org.apache.pig.backend.hadoop.hbase.HBaseStorage( 'A:*', '-loadKey true -caching=100000') AS (id:bytearray, A_map:map[]); In the code above, I want to basically build a histogram of id and how many items in column family A that key has. In hoping, I tried c = FOREACH data GENERATE id, COUNT(A_map); but that unsurprisingly didn't work. Or, perhaps someone can suggest a better way to do this entirely. If I can't figure this out soon I'll just write a Java MapReduce job or a Pig UDF.

• Changing <img src="XXX" />, js event when new image has finished loading?

  - by carillonator

  I have a photo gallery web page where a single <img src="XXX" /> element's src is changed (on a click) with javascript to show the next image—a poor man's ajax I guess. Works great on faster connections when the new image appears almost immediately. Even if it takes a few seconds to load, every browser I've tested it on keeps the old image in place until the new one is completely loaded. It's a little confusing waiting those few seconds on a slow connection, though, and I'm wondering if there's some javascript event that fires when the new image is done loading, allowing me to put a little working... animated gif or something up in the meantime. I know I could use AJAX for real (I'm using jQuery already), but this is such a nice and simple solution. Besides this lag, is there any other reason I should stay away from this approach to changing images? thanks.

• Performance of .NET ILMerged assemblies

  - by matt

  I have two .NET libraries: "Foo.Bar" and "Foo.Baz". "Foo.Bar" is self-contained, while "Foo.Baz" references "Foo.Bar". Assuming I do the following: Use ILMerge to merge "Foo.Bar.dll" with "Foo.Baz.dll" into "Foo1.dll". Create a new solution containing the entirity of both "Foo.Bar" and "Foo.Baz" (since I have access to their source code), and compile this into "Foo2.dll". Will there be any differences in the performance of Foo1.dll and Foo2.dll when using their functionality from an external project? If so, how significant is this performance difference, and is it a once-off (on load?) or ongoing difference? Are there any other pros or cons with either approach?

• Pinterest Gridview implementation on iOS

  - by Amal

  I want to implement a grid view like the one in Pinterest I thought about implementing as 3 table views. But I was not able to scroll them together well. When I implemented the scrollViewDidScroll and set the contentOffset for the table views other the scrollView , the scrolling became slow and unusable. Another implementation I did was of was having a set of images to load and calling the viewDraw function in scrollViewDidScroll. THe ViewDraw function just draws the necessary images and removes the rest of the images from the memory which were already drawn but wont be visible . this too makes the ScrollView Scrolling slow. And another issue with it is that there are white(background color) patches before the images are drawn. What should be the best way to implement this grid view ?

• reading 2 lines from IniFile

  - by Lakkerw

  Trying again. On advice, adding the piece of code that I do understand. I am fine with the fact that I have to save 4 bits of information in two lines like so: IniFile.WriteString('TestSection','Name','Country'); IniFile.WriteString('TestSection','City','Street'); My question is more about loading this information back into the form. If in my IniFile I have saved for example the following code [TestSection] John=Uk London=barlystreet Mike=Spain Madrid=eduardostrata Emma=USA New York=1st Avenue Made up information in the IniFile. Added through the code above. Now my question is: How could I load for example, when I type in an edit box Mike, the rest of the belonging information.(Spain, Madrid,eduardostrata).

• PHP Serialization Will not work correctly.

  - by stevoo

  Hi, I am developing and doing all the testing on a local machine using PHP Version 5.3.3-1ubuntu9.1 version. The host machine is PHP Version 5.2.15. All the seriliaze arguments are identical. The problems is when i try to login the user on my test local machine i do the following : $user->getByUserId($results['id'],$db); $_SESSION['user'] = serialize($user); which retrieved me and serialize the user. and i just load it back when ever i detect that a session exists $user->LoadFromObject(unserialize($_SESSION['user'])); This works perfectly on my test machine. Just transfered the files on the host to see if i can get a beta version out but i keep on getting Warning: unserialize() expects parameter 1 to be string, object given in /home/gamerent/public_html/beta/includes/header.php on line 19 i have noticed that if i echo the $_SESSION['user'] in both system the test will indeed display me the serializated one but the main one will just show me the object and will not serialize the $user

• Handling duplicate nodes in XML

  - by JYelton

  Scenario: I am parsing values from an XML file using C# and have the following method: private static string GetXMLNodeValue(XmlNode basenode, string strNodePath) { if (basenode.SelectSingleNode(strNodePath) != null) return (basenode.SelectSingleNode(strNodePath).InnerText); else return String.Empty; } To get a particular value from the XML file, I generally pass the root node and a path like "parentnode/item" I recently ran into an issue where two nodes at the same document level share the same name. Question: What is the best way to get the values for duplicate-named nodes distinctly? My thought was to load all values matching the node name into an array and then using the array index to refer to them. I'm not sure how to implement that, though. (I'm not well-versed in XML navigation.)
