• Does Java 6 open a default port for JMX remote connections?

  - by Bob Cross

  My specific question has to do with JMX as used in JDK 1.6: if I am running a Java process using JRE 1.6 with com.sun.management.jmxremote in the command line, does Java pick a default port for remote JMX connections? Backstory: I am currently trying to develop a procedure to give to a customer that will enable them to connect to one of our processes via JMX from a remote machine. The goal is to facillitate their remote debugging of a situation occurring on a real-time display console. Because of their service level agreement, they are strongly motivated to capture as much data as possible and, if the situation looks too complicated to fix quickly, to restart the display console and allow it to reconnect to the server-side. I am aware the I could run jconsole on JDK 1.6 processes and jvisualvm on post-JDK 1.6.7 processes given physical access to the console. However, because of the operational requirements and people problems involved, we are strongly motivated to grab the data that we need remotely and get them up and running again. EDIT: I am aware of the command line port property com.sun.management.jmxremote.port=portNum The question that I am trying to answer is, if you do not set that property at the command line, does Java pick another port for remote monitoring? If so, how could you determine what it might be?

• How can I make an even more random number in ActionScript 2.0

  - by Theo

  I write a piece of software that runs inside banner ads which generates millions of session IDs every day. For a long time I've known that the random number generator in Flash is't random enough to generate sufficiently unique IDs, so I've employed a number of tricks to get even more random numbers. However, in ActionScript 2.0 it's not easy, and I'm seeing more and more collisions, so I wonder if there is something I've overlooked. As far as I can tell the problem with Math.random() is that it's seeded by the system time, and when you have sufficient numbers of simultaneous attempts you're bound to see collisions. In ActionScript 3.0 I use the System.totalMemory, but there's no equivalent in ActionScript 2.0. AS3 also has Font.enumerateFonts, and a few other things that are different from system to system. On the server side I also add the IP address to the session ID, but even that isn't enough (for example, many large companies use a single proxy server and that means that thousands of people all have the same IP -- and since they tend to look at the same sites, with the same ads, roughly at the same time, there are many session ID collisions). What I need isn't something perfectly random, just something that is random enough to dilute the randomness I get from Math.random(). Think of it this way: there is a certain chance that two people will generate the same random number sequence using only Math.random(), but the chance of two people generating the same sequence and having, say, the exact same list of fonts is significantly lower. I cannot rely on having sufficient script access to use ExternalInterface to get hold of things like the user agent, or the URL of the page. I don't need suggestions of how to do it in AS3, or any other system, only AS2 -- using only what's available in the standard APIs. The best I've come up with so far is to use the list of microphones (Microphone.names), but I've also tried to make some fingerprinting using some of the properties in System.capabilities, I'm not sure how much randomness I can get out of that though so I'm not using that at the moment. I hope I've overlooked something.

• Template operator linker error

  - by Dani

  I have a linker error I've reduced to a simple example. The build output is: debug/main.o: In function main': C:\Users\Dani\Documents\Projects\Test1/main.cpp:5: undefined reference tolog& log::operator<< (char const (&) [6])' collect2: ld returned 1 exit status It looks like the linker ignores the definition in log.cpp. I also cant put the definition in log.h because I include the file alot of times and it complains about redefinitions. main.cpp: #include "log.h" int main() { log() << "hello"; return 0; } log.h: #ifndef LOG_H #define LOG_H class log { public: log(); template<typename T> log &operator <<(T &t); }; #endif // LOG_H log.cpp: #include "log.h" #include <iostream> log::log() { } template<typename T> log &log::operator <<(T &t) { std::cout << t << std::endl; return *this; }

• Does a VCL OrgChart component with decent features exists? Is there a viable alternative?

  - by user193655

  I am using DevExpress OrgChart component that is still maintained but not developed since 2003 (fortunately bugs are fixed, but nothing more). Honestly this component, even if it starts to look too old still suffices my requirements except for 2 things: 1) it doesn't support at all the staff feature, for understanding what I mean see this image (where the items in staff are Administration, Communication, IT, Special Projects). 2) it arranges the items without optimizing the space, for example if there are 3 items at top level, and only the second item has 2 childs, the top items items are drawn more distantly, because of the 2 childs, there is no an option for "shirinking" the diagram. Of course the component misses tons of the features one would expect from an OrgChart tool, but in my case Those 2, and expecially (1) are important, the rest is lack of eye-candy. I look for VCL components, but if (as I fear, since I never found it) such component doesn't exist) I can see the following alternatives: i) using Hydra with .net winforms components ii) using ActiveX components. Between the 2 I would prefer ActiveX because of the .NET deployment hell (what I like about Delphi is that you ship the exe to the customer witn Win2k and it works). Anyway I never used an activeX control and I don't know which are the deployment issues, but I fear I will lose the opportunity of replacing an exe and upgrading the software. iii) hire a delphi component develoeper that can customize the DevEx component by adding feature (1) and maybe (2). I am stuck.

• Should frontend and backend handled by different controllers?

  - by DR

  In my previous learning projects I always used a single controller, but know I wonder if that is good practice or even always possible. In all RESTful Rails tutorials the controllers have a show, an edit and an index view. If an authorized user is logged on, the edit view becomes available and the index view shows additional data manipulation controls, like a delete button or a link to the edit view. Now I have a Rails application which falls exactly into this pattern, but the index view is not reusable: The normal user sees a flashy index page with lots of pictures, complex layout, no Javascript requirement, ... The Admin user index has a completly different minimalistic design, jQuery table and lots of additional data, ... Now I'm not sure how to handle this case. I can think of the following: Single controller, single view: The view is split into two large blocks/partials using an if statement. Single controller, two views: index and index_admin. Two different controllers: BookController and BookAdminController None of this solutions seems perfect, but for now I'm inclined to use the 3rd option. What's the preferred way to do this?

• Understanding Domain Driven Design

  - by Nihilist

  Hi I have been trying to understand DDD for few weeks now. Its very confusing. I dont understand how I organise my projects. I have lot of questions on UnitOfWork, Repository, Associations and the list goes on... Lets take a simple example. Album and Tracks. Album: AlbumId, Name, ListOf Tracks Tracks: TrackId, Name Question1: Should i expose Tracks as a IList/IEnumerabe property on Album ? If that how do i add an album ? OR should i expose a ReadOnlyCollection of Tracks and expose a AddTrack method? Question2: How do i load Tracks for Album [assuming lazy loading]? should the getter check for null and then use a repository to load the tracks if need be? Question3: How do we organise the assemblies. Like what does each assembly have? Model.dll - does it only have the domain entities? Where do the repositories go? Interfaces and implementations both. Can i define IAlbumRepository in Model.dll? Infrastructure.dll : what shold this have? Question4: Where is unit of work defined? How do repository and unit of work communicate? [ or should they ] for example. if i need to add multiple tracks to album, again should this be defined as AddTrack on Album OR should there a method in the repository? Regardless of where the method is, how do I implement unit of work here? Question5: Should the UI use Infrastructure..dll or should there be ServiceLayer? Do my quesitons make sense? Regards

• What is the best database structure for this scenario?

  - by Ricketts

  I have a database that is holding real estate MLS (Multiple Listing Service) data. Currently, I have a single table that holds all the listing attributes (price, address, sqft, etc.). There are several different property types (residential, commercial, rental, income, land, etc.) and each property type share a majority of the attributes, but there are a few that are unique to that property type. My question is the shared attributes are in excess of 250 fields and this seems like too many fields to have in a single table. My thought is I could break them out into an EAV (Entity-Attribute-Value) format, but I've read many bad things about that and it would make running queries a real pain as any of the 250 fields could be searched on. If I were to go that route, I'd literally have to pull all the data out of the EAV table, grouped by listing id, merge it on the application side, then run my query against the in memory object collection. This also does not seem very efficient. I am looking for some ideas or recommendations on which way to proceed. Perhaps the 250+ field table is the only way to proceed. Just as a note, I'm using SQL Server 2012, .NET 4.5 w/ Entity Framework 5, C# and data is passed to asp.net web application via WCF service. Thanks in advance.

• jQuery Tablesorter - column not sorting alphabetically

  - by McGirl

  I'm not sure what's going wrong here. This is the page: http://www.utexas.edu/ssw/cswr/projects/project-list/ The first column sorts, but it isn't returning data in the correct order (alphabetical). The table itself is being generated by a custom PHP function that pulls info from a WordPress database. I thought that might be the issue, but as you can see the fourth column (End Date) sorts correctly. I also thought it might be the links in the first column that were messing things up, but adding the text-extraction code from this page broke the sorting altogether. This is the jQuery code I'm current using to call Tablesorter: <script type="text/javascript" id="js"> jQuery(document).ready(function($) { $(document).ready(function() { // call the tablesorter plugin, the magic happens in the markup $("#projectTable").tablesorter({ // pass the headers argument and assing a object //debug: true, //sortList: [[0,0]], headers: { 0: { // set the column to sort as text sorter: 'text', }, // assign the secound column (we start counting zero) 1: { // disable it by setting the property sorter to false sorter: false, }, // assign the third column (we start counting zero) 2: { // disable it by setting the property sorter to false sorter: false }, 3: { sorter:'digit' } } }); // Works only with plugin modification $("#projectTable").bind("sortStart",function(e) { if( $(e.target).hasClass('header') ) { $("#overlay").show(); } }).bind("sortEnd",function(e) { if( $(e.target).hasClass('header') ) { $("#overlay").hide(); } }); }); }); </script> Thanks for your help!

• Delphi App has "No Debug Info" when Debugging

  - by James L.

  We have built an application that uses packages and components. When we debug the application, the "Event Log" in the IDE often shows the our BPLs are being loaded without debug information ("No Debug Info"). This doesn't make sense because all our packages and EXEs are built with debug. _(each project) | Options | Compiling_ [ x ] Assertions [ x ] Debug information [ x ] Local symbols Symbol reference info = "Reference info" [ ] Use debug .dcus [ x ] Use imported data references _(each project) | Options | Linking_ [ x ] Debug information Map file = Detailed We have 4 projects, all built with runtime pacakges: Core.bpl Components.bpl Plugin.bpl (uses both #1 & #2) MainApp.exe (uses #1) Problems Observed 1) Many times when we debug, the Components.bpl is loaded with debug info, but all values in the "Local Variables" window are blank. If you hover your mouse over a variable in the code, there is no popup, and Evaluate window also shows nothing (the "Result" pane is always blank). 2) Sometimes the Event Log shows "No Debug Info" for various BPLs. For instance, if we activate the Plugin.bpl project and set it's Run | Parameter's Host Application to be the MainApp.exe, and then press F9, all modules seems to load with "Has Debug Info" except for the Plugin.bpl module. When it loads, the Event Log shows "No Debug Info". However, if we close the app and immediately press F9, it will run it again without recompiling anything and this time Plugin.bpl is loaded with debug ("Has Debug Info"). Questions 1) What would cause the "Local Variables" window to not display the values? 2) Why are BPLs sometimes loaded without debug info when the BPL was complied with debug and all the debug files (dcu, map, etc.) are available?

• Comet, responseText and memory usage

  - by ithcy

  Is there a way to clear out the responseText of an XHR object without destroying the XHR object? I need to keep a persistent connection open to a web server to feed live data to a browser. The problem is, there is a relatively large amount of data coming through (several hundred K per second constantly), so memory usage is a big problem, because this connection must remain open for at least several minutes. responseText gets very big very quickly, even though the JSON I send back has been crunched as small as it can get. Due to the way the server-side app works, if I use AJAX-style short polling and just destroy the XHR object when I'm done with it, I miss significant amounts of important data even in the few milliseconds it takes to parse the response, create a new XHR and send it out. I do not have the option to use overlapping requests, as the web server only accepts one connection at a time. (Don't ask.) So Comet is exactly the model I need. What I would like to do is parse each JSON chunk as it comes back from the server, and then clear out responseText so that I can keep using the same connection. However, responseText is read-only. It cannot be directly emptied by any method I have found. Is there a part of the picture I am missing here? Does anyone know any tricks I can use to free up responseText when I'm done reading it? Or is there another place the server responses can go? I am not including code because this is really almost a code-agnostic question. The Javascript routines that spawn the XHRs and handle the returned data are very, very simple.

• Looping login with Facebook JS SDK and Rails

  - by nafe

  I'm using the Facebook JS SDK for single-sign with my rails app. I translated the php code from the Facebook example (at the bottom of the page under "Single Sign-on with the JavaScript SDK") into ruby. This appeared to be working great but I've noticed one user that gets continual redirects when trying to login. The logs look like: Processing UsersController#login (for X.X.X.X at 2010-05-22 17:25:55) [GET] Redirected to http://myapp.com/ Completed in 0ms (DB: 0) | 302 Found [http://myapp.com/login] (times as many entries as my unfortunate user leaves the browser redirecting in a loop). My client side code includes a callback with the "auth.sessionChange": FB.Event.subscribe('auth.sessionChange', function(response) { if (response.session) { // A user has logged in, and a new cookie has been saved window.location = "/login"; } else { // The user has logged out, and the cookie has been cleared window.location = "/logout"; } }); So it seems to me like this event is continually firing. Although, I can't test this theory because I can't recreate this scenario locally. I don't think it's the rails controller. The code here is just: def login # if first time user create db entry # now redirect back to where the user came from begin redirect_to :back rescue ActionController::RedirectBackError redirect_to root_url end end Does anyone have any idea on what's going on?

• Updating MS Access Database from Datagridview

  - by Peter Roche

  I am trying to update an ms access database from a datagridview. The datagridview is populated on a button click and the database is updated when any cell is modified. The code example I have been using populates on form load and uses the cellendedit event. private OleDbConnection connection = null; private OleDbDataAdapter dataadapter = null; private DataSet ds = null; private void Form2_Load(object sender, EventArgs e) { string connetionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source='C:\\Users\\Peter\\Documents\\Visual Studio 2010\\Projects\\StockIT\\StockIT\\bin\\Debug\\StockManagement.accdb';Persist Security Info=True;Jet OLEDB:Database Password="; string sql = "SELECT * FROM StockCount"; connection = new OleDbConnection(connetionString); dataadapter = new OleDbDataAdapter(sql, connection); ds = new DataSet(); connection.Open(); dataadapter.Fill(ds, "Stock"); connection.Close(); dataGridView1.DataSource = ds; dataGridView1.DataMember = "Stock"; } private void addUpadateButton_Click(object sender, EventArgs e) { } private void dataGridView1_CellEndEdit(object sender, DataGridViewCellEventArgs e) { try { dataadapter.Update(ds,"Stock"); } catch (Exception exceptionObj) { MessageBox.Show(exceptionObj.Message.ToString()); } } The error I receive is Update requires a valid UpdateCommand when passed DataRow collection with modified rows. I'm not sure where this command needs to go and how to reference the cell to update the value in the database.

• PHP Single Sign On (SSO) generating new session id

  - by bigstylee

  I am trying to create a single sign on process. The method I have implemented makes use of storing session data in a database. When a new user comes to the website (www.example2.com) a table of authentication is checked. As this is their first visit to the website, there will be no match. The browser is redicted to the authentication server www.example1.com/authenticate.php?session_id=ABC123 where ABC123 represents the session id created on www.example2.com. THe session id which is then generated on www.example1.com is stored along side the session id using the parameter set in the URL. The user is then redirected back to the www.example2.com and a match of session ids should be found. This WAS working fine in FireFox but when I tried it in Chrome I noticed that the session id being generated when the browser is redirected back to www.example2.com is a new session id. As a result an infinite loop is created. This behaviour has not manifested itself in FireFox aswell. What is causing the new session id to be generated? More importantly, what can I do to stop it? Thanks in advance! EDIT I had a logically error that was causing an infinite loop. This now works fine again in FireFox but the infinite loop is still occuring in Chrome and Internet Explorer.

• Scaling Image to multiple sizes for Deep Zoom

  - by AnthonyWJones

  Lets assume I have a bitmap with a square aspect and width of 2048 pixels. In order to create a set of files need by Silverlight's DeepZoomImageTileSource I need to scale this bitmap to 1024 then to 512 then to 256 etc down to 1 pixel image. There are two, I suspect naive, approaches:- For each image required scale the original full size image to the required size. However it seems excessive to be scaling the full image to the very small sizes. Having scaled from one level to the next discard the original image and scale each sucessive scaled image as the source of the next smaller image. However I suspect that this would generate images in the 256-64 range with poor fidelity than using option 1. Note unlike with the Deep Zoom Composer this tool is expected to act in an on-demand fashion hence it needs to complete in a reasonable timeframe (tops 30 seconds). On the pluse side I'm only creating a single multiscale image not a pyramid of mutliple high-res images. I am outside my comfort zone here, any graphics experts got any advice? Am I wrong about point 2? Is point 1 reasonably performant and I'm worrying about nothing? Option 3?

• .Net Remoting: Serialize Object and implementation

  - by flogo

  Hi, In my scenario there is a client-side assembly that contains a class (Task). This class implements an interface (ITask) that is known on the server. I'm trying to send a Task object from client to server without copying the assembly of the client manually to the server. If I just serialize the task object, the server obviously complains about the missing assembly. I then tried to serialze typeof(Task).Assembly but could not derserialize it on the server. Next I tried to File.ReadAllBytes(typeof(Task).Assembly.Location) and saved it to a temporary file on the server, which threw an exception on Assembly.LoadFrom(@".\temporary.dll"); Why am I doing this? Java RMI has a neat feature to request the implementation of an object that is received through remoting but is stil "unkown" (this JVM doesn't have the *.class file). This can be used for a compute server that just knows the interface of a "task" containing a run() method and downloads the implementation of this method on demand. This way the server doesn't have to be changed for new tasks. I'm trying to achieve something like this in .Net.

• RavenDB Ids and ASP.NET MVC3 Routes

  - by goober

  Hey all, Just building a quick, simple site with MVC 3 RC2 and RavenDB to test some things out. I've been able to make a bunch of projects, but I'm curious as to how Html.ActionLink() handles a raven DB ID. My example: I have a Document called "reasons" (a reason for something, just text mostly), which has reason text and a list of links. I can add, remove, and do everything else fine via my repository. Below is the part of my razor view that lists each reason in a bulleted list, with an Edit link as the first text: @foreach(var Reason in ViewBag.ReasonsList) { <li>@Html.ActionLink("Edit", "Reasons", "Edit", new { id = Reason.Id }, null) @Reason.ReasonText</li> <ul> @foreach (var reasonlink in Reason.ReasonLinks) { <li><a href="@reasonlink.URL">@reasonlink.URL</a></li> } </ul> } The Problem This works fine, except for the edit link. While the values and code here appear to work directly (i.e the link is firing directly), RavenDB saves my document's ID as "reasons/1". So, when the URL happens and it passes the ID, the resulting route is "http://localhost:4976/Reasons/Edit/reasons/2". So, the ID is appended correctly, but MVC is interpreting it as its own route. Any suggestions on how I might be able to get around this? Do I need to create a special route to handle it or is there something else I can do?

• Can any linux API or tool watch for any change in any folder below e.g. /SharedRoot or do I have to

  - by Simon B.

  I have a folder with ~10 000 subfolders. Can any linux API or tool watch for any change in any folder below e.g. /SharedRoot or do I have to setup inotify for each folder? (i.e. I loose if I want to do this for 10k+ folders). I guess yes, since I've already seen examples of this inefficient method, for instance http://twistedmatrix.com/trac/browser/trunk/twisted/internet/inotify.py?rev=28866#L345 My problem: I need to keep folders time-sorted with most recently active "project" up top. When a file changes, each folder above that file should update its last-modified timestamp to match the file. Delays are ok. Opening a file (typically MS Excel) and closing again, its file date can jump up and then down again. For this reason I need to wait until after a file is closed, then queue the folder of that file for checking, and only a while later do I go and look for the newest file in its folder, since the filedate of the triggering file could already be back-dated to its original timestamp by Excel or similar programs. Also in case several files from same folder are used/created, it makes sense to buffer timestamping of that folders' parents to at least get a bunch of updates collapsed into one delayed update. I'm looking for a linux solution. I have some code that can be run on a windows server, most of the queing functionality is here: http://github.com/sesam/FolderdateFollowsFiles/blob/master/FolderdateFollowsFiles/Follower.vb Available API:s The relative of inotify on windows, ReadDirectoryChangesW, can watch a folder and its whole subtree; see bWatchSubtree on http://msdn.microsoft.com/en-us/library/aa365465(VS.85).aspx Samba? Patching samba source is a possibility, but perhaps there are already hooks available? Other possibilities, like client side (various windows versions) and spying on file activities in order to update folders recursively?

• PHP Session data not being saved

  - by Crackerjack

  I have one of those "I swear I didn't touch the server" situations. I honestly didn't touch any of the php scripts. The problem I am having is that php data is not being saved across different pages or page refreshes. I know a new session is being created correctly because I can set a session variable (e.g. $_SESSION['foo'] = "foo" and print it back out on the same page just fine. But when I try to use that same variable on another page it is not set! Is there any php functions or information I can use on my hosts server to see what is going on? Here is an example script that does not work on my hosts' server as of right now: <?php session_start(); if(isset($_SESSION['views'])) $_SESSION['views'] = $_SESSION['views']+ 1; else $_SESSION['views'] = 1; echo "views = ". $_SESSION['views']; echo '<p><a href="page1.php">Refresh</a></p>'; ?> The 'views' variable never gets incremented after doing a page refresh. I'm thinking this is a problem on their side, but I wanted to make sure I'm not a complete idiot first. Here is the phpinfo() for my hosts' server (PHP Version 4.4.7):

• What is better in WPF for UI layout, using one Grid, or nested Grids.

  - by Matthijs Wessels

  I am making a UI in WPF, I have a bunch of functional areas and I use a Grid to organize it. Now the Grid that I want is not uniform, as in, some functional area will span multiple cells in the Grid. I was wondering what the best practise is in solving this. Should I create one grid and then for each functional area set it to span multiple cells, or should I split it up into multiple nested Grids. In this image, the leftmost panel (panels separated by the gray bar) is what I want. The middle panel shows one grid where the blue lines are overlapped by a functional area. The rightmost panel shows how I could do it with nested grids. You can see the green grid has one horizontal split. In the bottom cell is the yellow Grid with a vertical split. In side the left cell is the red Grid with again a horizontal split. I was just wondering what is best practise, the middle or the right panel.

• CSS Width Greater then Page Width without Horizontal Scroll (overflow:hidden not an option)

  - by Anders H

  I've got a basic layout going in 960.gs. One line of text is absolutely positioned, starting within an inner DIV and exiting only the right side of the page. Here's a screenshot: The issue is that as the text appears as a series of unbroken words, if the width of the text box doesn't extend beyond the end of the page, it breaks some distance from the edge. overflow: hidden; doesn't do the trick because I need to set the width wider than the page. float won't work because the text can't escape the width of the inner DIV. I can't set it outside the inner DIV and just position it there as the same problem will still exist. The code is basically as simple as: <wrapper (containing) DIV> <text stripe DIV> <p></p> </text stripe DIV> </ wrapper DIV> I know I've done something like this before and I can't for the life of me remember what I ended up doing. Thanks.

• Bulk Insert of hundreds of millions of records

  - by Dave Jarvis

  What is the fastest way to insert 237 million records into a table that has rules (for distributing the data across 84 child tables)? First I tried inserts. No go. Then I tried inserts with BEGIN/COMMIT. Not nearly fast enough. Next, I tried COPY FROM, but then noticed the documentation states that the rules are ignored. (And it was having difficulties with the column order and date format -- it said that '1984-07-1' was not a valid integer; true, but a bit unexpected.) Some example data: station_id,taken,amount,category_id,flag 1,'1984-07-1',0,4, 1,'1984-07-2',0,4, 1,'1984-07-3',0,4, 1,'1984-07-4',0,4,T Here is the table structure (with one rule included): CREATE TABLE climate.measurement ( id bigserial NOT NULL, station_id integer NOT NULL, taken date NOT NULL, amount numeric(8,2) NOT NULL, category_id smallint NOT NULL, flag character varying(1) NOT NULL DEFAULT ' '::character varying ) WITH ( OIDS=FALSE ); ALTER TABLE climate.measurement OWNER TO postgres; CREATE OR REPLACE RULE i_measurement_01_001 AS ON INSERT TO climate.measurement WHERE date_part('month'::text, new.taken)::integer = 1 AND new.category_id = 1 DO INSTEAD INSERT INTO climate.measurement_01_001 (id, station_id, taken, amount, category_id, flag) VALUES (new.id, new.station_id, new.taken, new.amount, new.category_id, new.flag); I can generate the data into any format. Am looking for something that won't take four days. I originally had the data in MySQL (still do), but am hoping to get a performance increase by switching to PostgreSQL and am eager to use its PL/R extensions for stats. I was also thinking about using: http://pgbulkload.projects.postgresql.org/ Any help, tips, or guidance would be greatly appreciated. Thank you!

• Have I taken a wrong path in programming by being excessively worried about code elegance and style?

  - by Ygam

  I am in a major stump right now. I am a BSIT graduate, but I only started actual programming less than a year ago. I observed that I have the following attitude in programming: I tend to be more of a purist, scorning unelegant approaches to solving problems using code I tend to look at anything in a large scale, planning everything before I start coding, either in simple flowcharts or complex UML charts I have a really strong impulse on refactoring my code, even if I miss deadlines or prolong development times I am obsessed with good directory structures, file naming conventions, class, method, and variable naming conventions I tend to always want to study something new, even, as I said, at the cost of missing deadlines I tend to see software development as something to engineer, to architect; that is, seeing how things relate to each other and how blocks of code can interact (I am a huge fan of loose coupling) i.e the OOP thinking I tend to combine OOP and procedural coding whenever I see fit I want my code to execute fast (thus the elegant approaches and refactoring) This bothers me because I see my colleagues doing much better the other way around (aside from the fact that they started programming since our first year in college). By the other way around I mean, they fire up coding, gets the job done much faster because they don't have to really look at how clean their codes are or how elegant their algorithms are, they don't bother with OOP however big their projects are, they mostly use web APIs, piece them together and voila! Working code! CLients are happy, they get paid fast, at the expense of a really unmaintainable or hard-to-read code that lacks structure and conventions, or slow executions of certain actions (which the common reasoning against would be that internet connections are much faster these days, hardware is more powerful). The excuse I often receive is clients don't care about how you write the code, but they do care about how long you deliver it. If it works then all is good. Now, did my "purist" approach to programming may have been the wrong way to start programming? Should I just dump these purist concepts and just code the hell up because I have seen it: clients don't really care how beautifully coded it is?

• Spring MVC- several parts/views from a controller

  - by leeeroy

  i'm looking into using Spring MVC - how would I structure the fact that a page can be composed of several different views Consider a controller that's basically: public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { List<Post> posts = repository.getNewPosts(); return new ModelAndView("posts", "posts", posts); } However, I decide that on every page, I'd also want a side "pane" that shows data based on some logic. That "pane" would just be a .jsp that gets included from the above "posts" view, and I could change my controller to: public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { List<Post> posts = repository.getNewPosts(); List<Items> items= repository.getItems(); return new ModelAndView("model", "model", new MyCommonViewModel(posts,items)); } But then I'd have to change every controller to also do List<Items> items= repository.getItems(); , and change everything again the next time I come up with something new. This seems messy. How do I structure this ? `
