• Do AOP violate layered architecture for enterprise apps?

  - by redzedi

  The question(as stated in the title) comes to me as recently i was looking at Spring MVC 3.1 with annotation support and also considering DDD for an upcoming project. In the new Spring any POJO with its business methods can be annotated to act as controller, all the concerns that i would have addressed within a Controller class can be expressed exclusively through the annotations. So, technically i can take any class and wire it to act as controller , the java code is free from any controller specific code, hence the java code could deal with things like checking security , starting txn etc. So will such a class belong to Presentation or Application layer ?? Taking that argument even further , we can pull out things like security, txn mgmt and express them through annotations , thus the java code is now that of the domain object. Will that mean we have fused together the 2 layers? Please clarify

• Is Android IPC plumbing exposed in any official and/or supported way?

  - by mathrick

  I'm interested in knowing how much the IPC mechanisms are meant to be exposed to the outside world. That is, if I wanted to impersonate a dalvik VM instance without having my app actually written in Java, am I allowed to do so, or will the protocol change the next time I look away from the screen? If it's allowed, what are the stability guarantees or lack thereof? Is there anything like documentation, or am I supposed just to read the fine sources on android.git.kernel.org? The purpose of it all would be to write apps in !Java languages while retaining the ability to construct GUIs. I don't care or mind if the code is technically inside a dalvik process as a JNI callout, what I'm interested in is "if I'm really good at pretending I'm Java over the wire, can I do everything actual Java code can? Or is there something that's only available as Java bytecode and nothing else?"

• Using App Engine to update a database in a app

  - by tyczj

  I have been reading about app engine but I still dont know what I can and cant do with it in a android application. Basically what I want to do is be able to create/manage a database in the cloud that the app can pull down and update the local database if needed. Creation and managing would be done outside of the app by me. I dont know much about all of this as I am just getting started with it but I already have an application made, I just want to add this feature to it. I have never written any sort of Web Service calls or anything either but I have used them to get data and such Can this be done? Any tutorials out there to help me out?

• Possible to not use ID field but another column name? in Lift

  - by bstevens90

  I am connected to a oracle database from a scala/lift webapp. I have been able to successfully pull information from the database as I wished but am having one issue. For each table I want to access I am required to add an ID field so that the app will work with the trait IdPK. What mapper class or trait can I use to override this? I have been trying to find one but been unable to locate it. Figured people have not always had an ID field on every table they make that is just called ID... class DN_REC extends LongKeyedMapper[DN_REC] with IdPK { def getSingleton = DN_REC object dn_rec_id extends MappedInt(this){ } This is what I am talking about. I would like to use the dn_rec_id as my primary key as it is on the table. Thanks

• What should I do or learn to better prepare myself for a co-op position?

  - by Chris Vinz

  I'm currently taking computer systems in a technical institute and I will start looking for a coop job by next September. Since summer vacation is only a few weeks away, I was wondering what I should learn or do to help me land a job and do well in it. I'm pretty sure I'm ahead of most of my classmates since I got around 1.5 years "head start." For now, I'm planning to learn how to use source control (git - for no reason really) and was actually thinking of learning Scheme through SICP and maybe build something nice with it at the end. On the other hand, I'm wondering if it's better to expand on what I know right now and I'm thinking of C++ since I enjoy it a lot more than others like Java. Can I get advice on this? thanks!

• Can you set a form field value with PHP?

  - by dcp3450

  I use the $_GET function to pull a value with php from the url (http:..../index.html?variable=value), basic stuff. However, I need to use that value in my form. Typically, I would set <?php echo 'value="'.$variable.'"' ; ?> or something to that effect. However, I can't use php inside my form using the editor I'm working with. Can I set a value in the form without using PHP in my form? If so, how?

• Are there any FTP programs which can automatically send the contents of a folder to a remote server?

  - by Nick G

  Are there any FTP programs which can automatically copy (or rather 'move') the contents of a folder to a remote server? I have of course googled this but only really found one or two ancient products which look really clunky and unmaintained. I was wondering if there's a way to do this from the command line or any better solution to the base problem. In more detail, new files get written to a folder every few hours. These new files need to be FTP'd elsewhere and then deleted. Mirroring or synchonisation systems are probably out of the picture as we need to delete the source files once they've been successfully transferred. If it's easier, the 'solution' could pull the files off the server (rather than the server pushing them to the client). The computers will both be Windows OS.

  - by user306584

  trying to pick version control, continuous integration, and host for Flex + Ruby or Django smallish project. Question: version control: I've used SVN and CVS in the past. I hear great things about git. Not sure what to pick. continuous integration: I've heard good things about hudson and cruiseControl. Not sure what to pick hosting: is my own server the only way to go? Are the decent cloud options that are not too expensive? or should I look for some free hosting service? thank you for your help! f

• mysql select multiple rows in join

  - by julio

  Hi-- I have a simple mySQL problem-- I have two tables, one is a user's table, and one is a photos table (each user can upload multiple photos). I'd like to write a query to join these tables, so I can pull all photos associated with a user (up to a certain limit). However, when I do something obvious like this: SELECT *.a, *.b FROM user_table a JOIN photos_table b ON a.id = b.userid it returns a.id, a.name, a.email, a.address, b.id, b.userid, b.photo_title, b.location but it only returns a single photo. Is there a way to return something like: a.id, a.name, a.email, a.address, b.id, b.userid, b.photo_title, b.location, b.id2, b.photo_title2, b.location2 etc. . . for a given LIMIT of photos? Thanks for any ideas.

• Twitter Streaming API - tracking exact multiple keywords in exact order

  - by Gublooo

  Hey Guys, I'm just beginning to play with the Twitter Streaming API. If I specify $sc-setTrack(array('just bought from')); This will correctly pull only tweets that have all 3 keywords - but doesn't maintain the order. 1) I want the keywords to appear in the same order like "I just bought apple from itunes" but the above also returns tweets like "I bought some apples and just removed them from the bag" 2) Is there a way to specify the exact words say "NBA basketball" with nothing in between - in the sense I dont want tweets like this to be returned Watching basketball on NBA tv I just want tweets which contain the exact phrase to be returned like I love watching NBA basketball 3) Also is there a way to specify negative keywords Any tips if this is possible. Thanks

• Best Solution For Authentication in Ruby on Rails

  - by Dan Wolchonok

  I'm looking for a pre-built solution I can use in my RoR application. I'm ideally looking for something similar to the ASP.NET Forms authentication that provides email validation, sign-up controls, and allows users to reset their passwords. Oh yeah, and easily allows me to pull the user that is currently logged into the application. I've started to look into the already written pieces, but I've found it to be really confusing. I've looked at LoginGenerator, RestfulAuthentication, SaltedLoginGenerator, but there doesn't seem to be one place that has great tutorials or provide a comparison of them. If there's a site I just haven't discovered yet, or if there is a de-facto standard that most people use, I'd appreciate the helping hand.

• Passing URIs as URL arguments in Drupal 6

  - by wynz

  I'm running into problems trying to pass absolute URIs as parameters with clean URLs enabled. I've got hook_menu() set up like this: function mymodule_menu() { return array( 'page/%' = array( 'title' = 'DBpedia Display Test', 'page callback' = 'mymodule_dbpedia_display', 'page arguments' = array(1), ), ); } and in the page callback: function mymodule_dbpedia_display($uri) { // Make an HTTP request for this URI // and then render some things return $output; } What I'm hoping to do is somehow pass full URIs (e.g. "http://dbpedia.org/resource/Coffee") to my page callback. I've tried a few things and nothing's worked so far... http://mysite.com/page/http%3A%2F%2Fdbpedia.org%2Fresource%2FCoffee Completely breaks Drupal's rewriting http://mysite.com/page/?uri=http%3A%2F%2Fdbpedia.org%2Fresource%2FCoffee Gives a 404 http://mysite.com/page/http://dbpedia.org/resource/Coffee Returns just "http:", which makes sense I could probably use $_GET to pull out the whole query string, but I guess I'm hoping for a more 'Drupal' solution. Any suggestions?

• mod_rewrite rule for all urls except ones with some words

  - by zlog

  How do I write a mod_rewrite regulare expression rule that is the opposite of this: ^(.+)/path/(page1|page2)+$ ie, I want all pages except blah/path/page1 and blah/path/page2 to redirect to another path, where the x in blah/path/x is used in the new path. For example, I'd like write a rewrite rule like: RewriteRule some_regex /index.php?path/show/$1 [L] where some_regex would pull out the last component of a url in the format: /something/path/some_param to redirect to /index.php/path/show/some_param I'm trying to use ! and [^] syntax, but I don't quite understand how these work, especially when they involve words not single characters.

• Deploy tracking with Ruby on Rails and Capistrano

  - by TK

  Like every commit has a reason and purpose, I think each deploy has a purpose and reason. Source code commits have a comment. But deploying doesn't have any. How do I record a reason and purpose for each deploy automatically? I need to keep a record of: Who deployed to where and what time. Why deployed? Bug fixes? Feature update? Emergency fix not on iteration plan? Which git or svn ref was used? Have anybody felt the need for this kind of system? How do you feel about my approach? How can I achieve my goal? I'm currently using Capistrano for deployment.

• 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?

• C++ iterators & loop optimization

  - by Quantum7

  I see a lot of c++ code that looks like this: for( const_iterator it = list.begin(), const_iterator ite = list.end(); it != ite; ++it) As opposed to the more concise version: for( const_iterator it = list.begin(); it != list.end(); ++it) Will there be any difference in speed between these two conventions? Naively the first will be slightly faster since list.end() is only called once. But since the iterator is const, it seems like the compiler will pull this test out of the loop, generating equivalent assembly for both.

• How do you install cocos2d-iphone on the Mac?

  - by johnfromberkeley

  There are no good instructions for installing cocos2d for iPhone on the mac. I downloaded the current build from git, a folder called "cocos2d-iphone-0.99.1". i put this folder in /Developer/Libary. Q: is this right? I tried running the file called "install_template.sh". it said the templates were already installed. Instead, I manually dragged the templates folders where they belong, and they ~do~ appear in the XCode's "New Project" dialog. When I create a new cocos2d project, I see all these red links for project files, instead of the regular black links. When I try to open them in the finder, nothing happens. I can tell that something is not linked. Can someone please help walk me through this? Thanks!

• I need a very simple PHP database front-end admin panel; a simple records editor for a specified tab

  - by Lansen Q

  Hi there, I am looking to add some dynamics to our corporate website. This is a secondary role so I'd rather not be spending a ton of time on it. At this point, all I need is a simple PHP script where a non-technical user can pull up and manage the records in a MySQL table. There's only one table of data to be managed; it's just that it will be accessed and updated quite frequently. I recall that Grails' default scaffolding feature has precisely this: list of entries with the ability to add, edit and delete, with no nonsense. What would be the best tool to use for this? I would rather not be writing it from scratch, as this will take me quite some time. It seems like the kind of thing that ought to exist somewhere. Thanks!

• Displaying Data from a Join in Codeigniter

  - by Brad

  I am using a simple join to pull data from two databases. This is the join in the model function com_control(){ $this->db->select('*'); $this->db->from('comments'); $this->db->join('posts', 'comments.entry_id = posts.id'); $query = $this->db->get(); return $query->result; } My desired method of display is going to be in a table so I am starting out to use like this foreach($comm_control as $row){ $this->table->add_row( $row->entry_id, $row->comments.id, $row->comment, $row->title ); }//end of foreach My problem is the display of data from comments.id. What is the proper format to add the comment.id into the table rows? I need the ID from both tables for display, edit and delete further on in the table. The only display I get at this time for "comment.id" is the word id. The Any help would be appreciated.

• Without using PECL or system() type functions, is there a way to look up DNS records using PHP?

  - by Navarr

  I'm working on creating a new type of email protocol, and in order to do that I had to set up an SRV DNS record for my domain. In promoting this protocol, I'll need to be able to discover if a given host uses my system (and if not fall back to an older protocol). So, is there a way to pull a DNS record (such as SRV) using PHP without using a PECL extension or running it through the linux command line (I already know I can ob_start() and system("host -t SRV hostname") but I'm looking for a better way, if it exists.)

• Creative an interactive GUI for a web application

  - by user2125844

  I have to create a web application (preferably using the Google App Engine) that will allow users to access it through a url link (not a Desktop application). The application graphically looks like a flow chart and each item in the chart can be selected to pull up a video (not in another window). It is recommended that I use Python. I have never made anything for the web before. Is there a best Python GUI API I should use? I've read quite a bit about Django so far I'm not sure if it is the best fit for this or not. Does anyone have any tips for starting this project? Thanks in advance!

• SSIS Migration - Pulling IDs from dest DB?

  - by TheSciz

  So I'm working on migrating some data to a new server. In the new server, each entry in the MAIN table is assigned a new GUID when the transfer takes place. A few other tables must be migrated, and their records must link to the GUID in the MAIN table. Example... WorksheetID --- GUID 1245677903 --- 1 AccidentID --- WorksheetID --- Guid 12121412 --- 1245677903 --- 1 The guid is used moreso for versioning purposes, but my question is this. In SSIS, is there any way to pull the Worksheet's GUID from the destination database and assign it directly to the entries in the 'Accident' table? Or do I have to just dump the data into the source DB and run some scripts to get everything nicely referenced? Any help would be greatly appreciated.
