• Do you leverage the benefits of the open-closed principle?

  - by Kaleb Pederson

  The open-closed principle (OCP) states that an object should be open for extension but closed for modification. I believe I understand it and use it in conjunction with SRP to create classes that do only one thing. And, I try to create many small methods that make it possible to extract out all the behavior controls into methods that may be extended or overridden in some subclass. Thus, I end up with classes that have many extension points, be it through: dependency injection and composition, events, delegation, etc. Consider the following a simple, extendable class: class PaycheckCalculator { // ... protected decimal GetOvertimeFactor() { return 2.0M; } } Now say, for example, that the OvertimeFactor changes to 1.5. Since the above class was designed to be extended, I can easily subclass and return a different OvertimeFactor. But... despite the class being designed for extension and adhering to OCP, I'll modify the single method in question, rather than subclassing and overridding the method in question and then re-wiring my objects in my IoC container. As a result I've violated part of what OCP attempts to accomplish. It feels like I'm just being lazy because the above is a bit easier. Am I misunderstanding OCP? Should I really be doing something different? Do you leverage the benefits of OCP differently? Update: based on the answers it looks like this contrived example is a poor one for a number of different reasons. The main intent of the example was to demonstrate that the class was designed to be extended by providing methods that when overridden would alter the behavior of public methods without the need for changing internal or private code. Still, I definitely misunderstood OCP.

• What are my choices for server side sandboxed scripting?

  - by alfa64

  I'm building a public website where users share data and scripts to run over some data. The scripts are run serverside in some sort of sandbox without other interaction this cycle: my Perl program reads from a database a User made script, adds the data to be processed into the script ( ie: a JSON document) then calls the interpreter, it returns the response( a JSON document or plain text), i save it to the database with my perl script. The script should be able to have some access to built in functions added to the scripting language by myself, but nothing more. So i've stumbled upon node.js as a javascript interpreter, and and hour or so ago with Google's V8(does v8 makes sense for this kind of thing?). CoffeeScript also came to my mind, since it looks nice and it's still Javascript. I think javascript is widespread enough and more "sandboxeable" since it doesn't have OS calls or anything remotely insecure ( i think ). by the way, i'm writing the system on Perl and Php for the front end. To improve the question: I'm choosing Javascript because i think is secure and simple enough to implement with node.js, but what other alternatives are for achieving this kind of task? Lua? Python? I just can't find information on how to run a sandboxed interpreter in a proper way.

• Using HTML5 Today part 4&ndash;What happened to XHTML?

  - by Steve Albers

  This is the fourth entry in a series of descriptions & demos from the “Using HTML5 Today” user group presentation. For practical purposes, the original XHTML standard is a historical footnote, although XHTML transitional will probably live on forever in the default web page templates of old web page editors. The original XHTML spec was released in 2000, on the heels of the HTML 4.01 spec.  The plan was to move web development away from HTML to the more formal, rigorous approach that XHTML offered, but it was built on a principle that conflicts with the history and culture of the Internet: XHTML introduced the idea of Draconian Error Handling, which essentially means that invalid XML markup on a page will cause a page to stop rendering. There is a transitional mode offered in the original XHTML spec, but the goal was to move to D.E.H.  You can see the result by changing the doc type for a document to “application/xhtml+xml” - for my class example we change this setting in the web.config file: <staticContent> <remove fileExtension=".html" /> <mimeMap fileExtension=".html" mimeType="application/xhtml+xml" /> </staticContent> With the new strict syntax a simple error, in this case a duplicate </td> tag, can cause a critical page error: While XHTML became very popular in the ensuing decade, the Strict form of XHTML never achieved widespread use. Draconian Error Handling was one of the factors that led in time to the creation of the WHATWG, or Web Hypertext Application Technology Group.  WHATWG contributed to the eventually disbanding of the XHTML 2.0 working group and the W3C’s move to embrace the HTML5 standard. For developers who long for XML markup the W3C HTML5 standard includes an XHTML5 syntax. For the longer, more definitive look at what happened to XHTML and how HTML5 came to be check out the Dive Into HTML mirror site or Bruce Lawson’s “HTML5: Who, What, When Why” talk.

• Messages do not always appear in [catalog].[event_messages] in the order that they occur [SSIS]

  - by jamiet

  This is a simple heads up for anyone doing SQL Server Integration Services (SSIS) development using SSIS 2012. Be aware that messages do not always appear in [catalog].[event_messages] in the order that they occur, observe… In the following query I am looking at a subset of messages in [catalog].[event_messages] and ordering them by [event_message_id]: SELECT [event_message_id],[event_name],[message_time],[message_source_name]FROM   [catalog].[event_messages] emWHERE  [event_message_id] BETWEEN 290972 AND 290982ORDER  BY [event_message_id] ASC--ORDER BY [message_time] ASC Take a look at the two rows that I have highlighted, note how the OnPostExecute event for “Utility GetTargetLoadDatesPerETLIfcName” appears after the OnPreExecute event for “FELC Loop over TargetLoadDates”, I happen to know that this is incorrect because “Utility GetTargetLoadDatesPerETLIfcName” is a package that gets executed by an Execute Package Task prior to the For Each Loop “FELC Loop over TargetLoadDates”: If we order instead by [message_time] then we see something that makes more sense: SELECT [event_message_id],[event_name],[message_time],[message_source_name]FROM   [catalog].[event_messages] emWHERE  [event_message_id] BETWEEN 290972 AND 290982--ORDER BY [event_message_id] ASCORDER  BY [message_time] ASC We can see that the OnPostExecute for “Utility GetTargetLoadDatesPerETLIfcName” did indeed occur before the OnPreExecute event for “FELC Loop over TargetLoadDates”, they just did not get assigned an [event_message_id] in chronological order. We can speculate as to why that might be (I suspect the explanation is something to do with the two executables appearing in different packages) but the reason is not the important thing here, just be aware that you should be ordering by [message_time] rather than [event_message_id] if you want to get 100% accurate insights into your executions. @Jamiet

• use subdomain on different host

  - by Roy

  I want to accomplish something that I thought was simple. My wish is as follows: I have a domainname with hosting, a WordPress multisite (with subfolder setup) installed and running: gangleri.nl. I have another domain at another host and without hosting: monas.nl I created a subdomain on gangleri.nl: monas.gangleri.nl and the domain redirects to that subdomain. Now what I want is to have monas.nl act like a website, not a website in a subdomain. I would like to have post urls as in monas.nl/posttitle. I first thought to do this with the DNS settings of Monas.nl. I now have an URL forward, CURL is not what I want and I did not manage to get A-records or CNAMEs to work. I tried using the htaccess file of the WP installation in monas.gangleri.nl. I tried 301, rewrite and whatnot, but also without success. Meanwhile, I have been reading so much that I no longer have a clue what to do. A-record doesn't sound probable, since I have no IP for the subdomain, so an A-record would point to gangleri.nl rather than using the subdomain. Also I have no idea if I should do something in the DNS settings of gangleri.nl or monas.nl, both, one of them and something somewhere else. I have the idea that I've tried everything, but the more I try and read about it, the less I can get my head around. People talking about A-records to subdomains while I can only use IPs, CNAME settings that my host doesn't support or something. Could somebody tell me if what I want is possible and if so, take me by the hand and guide me through it?

• Create a custom shortcut that types clipboard contents

  - by briankb

  I want to paste my clipboard contents to a remote session such as VNC, IPMI, or Raritan. To accomplish this, I installed xdotool and clip. Then I wrote a simple command that types the clipboard contents: xdotool type "$(xclip -o)" This works if I stay in a terminal window, and type that command myself. It types back my clipboard contents when I run the command. Of course now I want to make this into a hotkey that works in any window. However, if I create a custom shortcut using Keyboard settings, it doesn't work. If I assign a hotkey Alt+K to the shortcut, nothing happens when I press it. If I use Ctrl+K, unexpected behavior occurs to whatever window has focus. e.g. my terminal window size shrinks (it's somewhat amusing, actually). Similar results occur if I save it as a script and call the script, or if I encapsulate the command with sh -c. How can I make practical use of the powerful xdotool type command?

• Presentation Plugin for NetBeans IDE 7.2

  - by Geertjan

  I got some excellent help from Mark Stephens, who is from IDR Solutions, which produces JPedal. Using the LGPL version of JPedal, and code provided by Mark, it's now possible to right-click the node that appears in the Presentation Window: ...after which, using a file browser (to locate a file on disk) or a URL (a very simple check is done, the URL must start with "http" and end with "pdf"), you can now open PDF files as images (thanks to conversion from PDF to images done by JPedal) into NetBeans IDE, typically (I imagine) for presentation purposes: Note that you should consider the plugin in "alpha" state. But, despite that, I've had good results. Try it and use the URL below, as a control test (since it works fine for me), which produces the result shown above: http://edu.netbeans.org/contrib/slides/netbeans-platform/presentation-4-actions.pdf  However, for some PDFs, the plugin doesn't work, and I don't know why yet (trying to figure it out with Mark), resulting in this stack trace: java.lang.ArrayIndexOutOfBoundsException: 8 at org.jpedal.objects.acroforms.formData.SwingData.completeField(Unknown Source) at org.jpedal.objects.acroforms.rendering.DefaultAcroRenderer.createField(Unknown Source) at org.jpedal.objects.acroforms.rendering.DefaultAcroRenderer.createDisplayComponentsForPage(Unknown Source) at org.jpedal.PDFtoImageConvertor.convert(Unknown Source) at org.jpedal.PdfDecoder.getPageAsImage(Unknown Source) at org.jpedal.PdfDecoder.getPageAsImage(Unknown Source) Here's the location of the plugin, install it into NetBeans IDE 7.2; feedback is very welcome: http://plugins.netbeans.org/plugin/44525

• What are the requirements to test a website using jquery.get() ? [migrated]

  - by Frankie

  I am working on a simple website. It has to search quite a few text files in different sub-folders. The rest of the page uses jquery, so I would like to use it for this also. The function I am looking at is .get() for downloading the files. So my main question is, can I test this on my local computer (Ubuntu Linux) or do I have to have it uploaded to a server? Also, if there's a better way to go about this, that would be nice to know. However, I'm more worried about getting it working. Thanks, Frankie PS: Heres the JS/jQuery code for downloading the files to an array. g_lists = new Array(); $(":checkbox").each(function(i){ if ($(this).attr("name") != "0") { var path = "../" + $(this).attr("name") + ".txt"; $("#bot").append("<br />" + path); // debug $.get(path, function(data){ g_lists[i] = data; $("#bot").html(data); }); } else { g_lists[i] = ""; } }); Edit: Just a note about the path variable. I think it's correct, but I'm not 100% sure. I'm new to web development. Here's some examples it produces and the directory tree of the site. Maybe it will help, can't hurt. . +-- include ¦   +-- jquery.js ¦   +-- load.js +-- index.xhtml +-- style.css +-- txt    +-- Scripting_Tools    +-- Editors.txt    +-- Other.txt Examples of path: ../txt/Scripting_Tools/Editors.txt ../txt/Scripting_Tools/Other.txt Well I'm a new user, so I can't "answer" my own question, so I'll just post it here: After asking for help on a IRC chat channel specific to jQuery, I was told I could use this on a local host. To do this I installed Apache web server, and copied my site into it's directory. More information on setting it up can be found here: http://www.howtoforge.com/ubuntu_debian_lamp_server Then to run the site I navigated my browser to "localhost" and everything works.

• When to use PHP or ASP.NET? [closed]

  - by loyalpenguin

  I have worked extensively in developing web applications using PHP and ASP.NET, but one of the questions that I'm constantly asked by customers is whether to move forward with a php website or an asp.net website. So naturally the first thing that comes to mind is to answer the question like this: PHP is open-source and ASP.NET is from Microsoft. Usually after something like that is said the customer has a blank look on there face. Apparently the fact that one is open source and the other isn't doesn't really faze them. And for good reason, because when I first heard it, it really doesn't tell me much. I know from working with both that each have their + and - when it comes to developing websites. NOTE: THIS QUESTION IS NOT TO QUESTION WHICH IS BETTER TO DEVELOP WITH. THIS QUESTION IS INTENDED TO BE OBJECTIVE. My question is what are differences between ASP.NET and PHP as far as Features Security Extendability Frameworks Average Development Time And when one is generally used over the other for certain types of projects. I am trying to compile a list of facts to be able to compare with the customer what developement platform is better for there particular project. I have done a simple search on google and a ton of articles come up, but the problem is the majority are usually biased towards PHP or ASP.NET. Also if you can maybe provide examples from experience when one technology was more preferable than the other that would be awesome.

• Should we test all our methods?

  - by Zenzen

  So today I had a talk with my teammate about unit testing. The whole thing started when he asked me "hey, where are the tests for that class, I see only one?". The whole class was a manager (or a service if you prefer to call it like that) and almost all the methods were simply delegating stuff to a DAO so it was similar to: SomeClass getSomething(parameters) { return myDao.findSomethingBySomething(parameters); } A kind of boilerplate with no logic (or at least I do not consider such simple delegation as logic) but a useful boilerplate in most cases (layer separation etc.). And we had a rather lengthy discussion whether or not I should unit test it (I think that it is worth mentioning that I did fully unit test the DAO). His main arguments being that it was not TDD (obviously) and that someone might want to see the test to check what this method does (I do not know how it could be more obvious) or that in the future someone might want to change the implementation and add new (or more like "any") logic to it (in which case I guess someone should simply test that logic). This made me think, though. Should we strive for the highest test coverage %? Or is it simply an art for art's sake then? I simply do not see any reason behind testing things like: getters and setters (unless they actually have some logic in them) "boilerplate" code Obviously a test for such a method (with mocks) would take me less than a minute but I guess that is still time wasted and a millisecond longer for every CI. Are there any rational/not "flammable" reasons to why one should test every single (or as many as he can) line of code?

• Flash Player for IPTV

  - by Le Mystique

  Hi All, We have to design a flash player for three video sources of IPTV. Educational videos on the system that can be played on demand. (VOD or Video on Demand local) Streaming videos available on different websites that can be played on demand (VOD or Video on Demand remote) IPTV live streaming video feed Videos from three sources have to be played within single flash player that we need to design. There are 2 basic requirements: For the two VOD types, we have to provide the pause and play functionality. For IPTV, pause and play is not required, However, channel switching time is critically important here. The user should get the program behaviour as close to TV experience as possible. This means channel switching should be fast. To provide this, buffering of video is required for multiple channels. Now the questions is, is this possible? If yes, how? Secondly, what skill set (e.g. action script 3.0 , flash 10) should the flash programmer have to be able to design this? Thirdly is it as simple as making a normal FLV player? Or is it a more complex job?

• How to pass one float as four unsigned chars to shader by glVertexPointAttrib?

  - by Kog

  For each vertex I use two floats as position and four unsigned bytes as color. I want to store all of them in one table, so I tried casting those four unsigned bytes to one float, but I am unable to do that correctly... All in all, my tests came to one point: GLfloat vertices[] = { 1.0f, 0.5f, 0, 1.0f, 0, 0 }; glEnableVertexAttribArray(0); glVertexAttribPointer(0, 2, GL_FLOAT, GL_FALSE, 2 * sizeof(float), vertices); // VER1 - draws red triangle // unsigned char colors[] = { 0xff, 0, 0, 0xff, 0xff, 0, 0, 0xff, 0xff, 0, 0, // 0xff }; // glEnableVertexAttribArray(1); // glVertexAttribPointer(1, 4, GL_UNSIGNED_BYTE, GL_TRUE, 4 * sizeof(GLubyte), // colors); // VER2 - draws greenish triangle (not "pure" green) // float f = 255 << 24 | 255; //Hex:0xff0000ff // float colors2[] = { f, f, f }; // glEnableVertexAttribArray(1); // glVertexAttribPointer(1, 4, GL_UNSIGNED_BYTE, GL_TRUE, 4 * sizeof(GLubyte), // colors2); // VER3 - draws red triangle int i = 255 << 24 | 255; //Hex:0xff0000ff int colors3[] = { i, i, i }; glEnableVertexAttribArray(1); glVertexAttribPointer(1, 4, GL_UNSIGNED_BYTE, GL_TRUE, 4 * sizeof(GLubyte), colors3); glDrawArrays(GL_TRIANGLES, 0, 3); Above code is used to draw one simple red triangle. My question is - why do versions 1 and 3 work correctly, while version 2 draws some greenish triangle? Hex values are one I read by marking variable during debug. They are equal for version 2 and 3 - so what causes the difference?

• Defining formula through user interface in user form

  - by BriskLabs Pakistan

  I am a student and developing a simple assignment - windows form application in visual studio 2010. The application is suppose to construct formulas as per user requirement. The process: It has to pick data from columns of Microsoft Access database and the user should be able to pick the data by column name like we do in a drop down menu. and create reusable formulas in it ( configure it once and can change it again). followings are column titles from database that can be picked for example. e.g Col -1 : Marks in Maths Col -2 : Total Marks in Maths Col -3 : Marks in science Col -4 : Total marks in science Finally we should be able to construct any formula in the UI like (Col 1 + Col 3 ) / ( col 2 + col 4) = Formula 1 once this is formula is set saved and a name is assigned to it by user. he/she can use the formula and results shall appear in a window below. i.e He would be able to calculate his desired figures (formula) by only manipulating underlying data on the UI layer....choose the data for a period and apply the formula and get the answer Problem: It looks like I have to create an app where rules are set through UI....... this means no stored procedures are required in SQL.... please suggest the right approach.

• How exactly to implement multiple threads in a game

  - by xerwin

  So I recently started learning Java, and having a interest in playing games as well as developing them, naturally I want to create game in Java. I have experience with games in C# and C++ but all of them were single-threaded simple games. But now, I learned how easy it is to make threads in Java, I want to take things to the next level. I started thinking about how would I actually implement threading in a game. I read couple of articles that say the same thing "Usually you have thread for rendering, for updating game logic, for AI, ..." but I haven't (or didn't look hard enough) found example of implementation. My idea how to make implementation is something like this (example for AI) public class AIThread implements Runnable{ private List<AI> ai; private Player player; /*...*/ public void run() { for (int i = 0; i < ai.size(); i++){ ai.get(i).update(player); } Thread.sleep(/* sleep until the next game "tick" */); } } I think this could work. If I also had a rendering and updating thread list of AI in both those threads, since I need to draw the AI and I need to calculate the logic between player and AI(But that could be moved to AIThread, but as an example) . Coming from C++ I'm used to do thing elegantly and efficiently, and this seems like neither of those. So what would be the correct way to handle this? Should I just keep multiple copies of resources in each thread or should I have the resources on one spot, declared with synchronized keyword? I'm afraid that could cause deadlocks, but I'm not yet qualified enough to know when a code will produce deadlock.

• Is the way I'm implementing my genetic algorithm right?

  - by Mhjr

  In my graduation project, I am asked to use a genetic algorithm (any variation of it can be chosen) to generate valid timetables. What I did was make a simple program that generates unique sequences representing genes, the sequence is described below: (sorry if it's mathematically incorrect) The only variable in the sequence is the room element, so basically the program takes a tree that goes like this: [Course] -(contains)-> [Units] -(contains)-> [Offerings] -(contains)-> [Instructors] -(contains)-> [Rooms] Each course can have n units (duplicates). Each unit can have n offerings (lectures,lab session, excercises,...). Each offering has only 1 instructor. Each instructor (or the whole lecture composed from the four elements of the sequence) has multiple rooms. When a timetable is initialized, one of these sequences that differ in rooms will be taken into the timetable, so the difference in genes (sequences) of each timetable will be just the rooms random choice and the difference between chromosomes (timetables) will be time placements of these genes (sequences). My question is, before I proceed in implementing what I described, is it valid? Is the representation used here for chromosomes a permutation representation?

• First Project a big one, How much should we charge?

  - by confuzzled

  Two of my cousins and I started a freelance computer repair/web design business just to make some money on the side during college, and received our first major web design project about three weeks ago. Now we've created websites before, but it was mostly for family businesses and have never really charged money, and most of the websites have been static, and don't really require a CMS. This project, however, was a big one (for us anyways). We created a news site that had several categories, we created the banners, we created a classifieds page (not a web app just something static that they control). Several links, a few graphical assets, CSS drop down menu, RSS feed from a different news site, weather, all the normal stuff you would find on a regular news site. On top of that we put in all the usual Joomla stuff (search, Jcomments, Jslide pictures, JCE, etc.). Then we uploaded the first 10 articles they gave us, and we are going to train them how to use Joomla. Now, at first we decided for 700 dollars. I assumed they just wanted a simple blog like website where they can upload articles. But then we had a meeting, and they asked for a lot more. Note: we did not hard code the template from scratch, but customized the gantry framework to fit their needs. We did code quite a bit however. I estimate that we put in about 50-60 hours in total. I'm wondering if 700 dollars is a bit low, this price is definitely not set in stone. Please keep in mind that this is our first project, and we are newbies, please be kind. Thank You!

• How should I structure moving from overworld to menu system / combat?

  - by persepolis

  I'm making a text-based "Arena" game where the player is the owner of 5 creatures that battle other teams for loot, experience and glory. The game is very simple, using Python and a curses emulator. I have a static ASCII map of an "overworld" of sorts. My character, represented by a glyph, can move about this static map. There are locations all over the map that the character can visit, that break down into two types: 1) Towns, which are a series of menus that will allow the player to buy equipment for his team, hire new recruits or do other things. 2) Arenas, where the player's team will have a "battle" interface with actions he can perform, messages about the fight, etc. Maybe later, an ASCII representation of the fight but for now, just screens of information with action prompts. My main problem is what kind of design or structure I should use to implement this? Right now, the game goes through a master loop which waits for keyboard input and then moves the player about the screen. My current thinking is this: 1) Upon keyboard input, the Player coordinates are checked against a list of Location objects and if the Player coords match the Location coords then... 2) ??? I'm not sure if I should then call a seperate function to initiate a "menu" or "combat" mode. Or should I create some kind of new GameMode object that contains a method itself for drawing the screen, printing the necessary info? How do I pass my player's team data into this object? My main concern is passing around the program flow into all these objects. Should I be calling straight functions for different parts of my game, and objects to represent "things" within my game? I was reading about the MVC pattern and how this kind of problem might benefit - decouple the GUI from the game logic and user input but I have no idea how this applies to my game.

• OpenGL lighting with dynamic geometry

  - by Tank

  I'm currently thinking hard about how to implement lighting in my game. The geometry is quite dynamic (fixed 3D grid with custom geometry in each cell) and needs some light to get more depth and in general look nicer. A scene in my game always contains sunlight and local light sources like lamps (point lights). One can move underground, so sunlight must be able to illuminate as far as it can get. Here's a render of a typical situation: The lamp is positioned behind the wall to the top, and in the hollow cube there's a hole in the back, so that light can shine through. (I don't want soft shadows, this is just for illustration) While spending the whole day searching through Google, I stumbled on some keywords like deferred rendering, forward rendering, ambient occlusion, screen space ambient occlusion etc. Some articles/tutorials even refer to "normal shading", but to be honest I don't really have an idea to even do simple shading. OpenGL of course has a fixed lighting pipeline with 8 possible light sources. However they just illuminate all vertices without checking for occluding geometry. I'd be very thankful if someone could give me some pointers into the right direction. I don't need complete solutions or similar, just good sources with information understandable for someone with nearly no lighting experience (preferably with OpenGL).

• How to Structure a Trinary state in DB and Application

  - by ABMagil

  How should I structure, in the DB especially, but also in the application, a trinary state? For instance, I have user feedback records which need to be reviewed before they are presented to the general public. This means a feedback reviewer must see the unreviewed feedback, then approve or reject them. I can think of a couple ways to represent this: Two boolean flags: Seen/Unseen and Approved/Rejected. This is the simplest and probably the smallest database solution (presumably boolean fields are simple bits). The downside is that there are really only three states I care about (unseen/approved/rejected) and this creates four states, including one I don't care about (a record which is seen but not approved or rejected is essentially unseen). String column in the DB with constants/enum in application. Using Rating::APPROVED_STATE within the application and letting it equal whatever it wants in the DB. This is a larger column in the db and I'm concerned about doing string comparisons whenever I need these records. Perhaps mitigatable with an index? Single boolean column, but allow nulls. A true is approved, a false is rejected. A null is unseen. Not sure the pros/cons of this solution. What are the rules I should use to guide my choice? I'm already thinking in terms of DB size and the cost of finding records based on state, as well as the readability of code the ends up using this structure.

• How do I find information on who links to my sites?

  - by bobdobbs

  I'm trying to figure out if there's a free way to get information on backlinks to my site. I've had webmaster tools and google analytics set up for years. But I can't find access to data about site backlinks in either toolset. Webmaster tools, under 'traffic'-'links to your site' gives me the same message for all of my sites: "No data available". I haven't been able to find anything in GA that gives any information on backlinks. I've heard of using "links:" as an operator in google search, but for each of my sites, this returns either zero or very few results in cases when I know I have many backlinks. Most of the links simple aren't shown. My thinking is that google maintains a graph of who links to my site, so I figured that they might let me see it. But I can't figure out how. I've found this tool on a spammy website: http://www.backlinkwatch.com. It offers more data than google on my backlines, and offers more results in exchange for a paid subscription. The data it offers for free looks good, but the results are limited and the site has popups and obnoxious ads. So, in short: how do I get data on who links to me? Is there a free way?

• Dojo and Separate JavaScript File

  - by Bunch

  For a project I needed to use the ArcGIS API for some mapping. To use this you need to use Dojo but in this case all it really comes down to is adding some require lines and a addOnLoad on your web page. At first everything was working great, the maps rendered and the various layers would populate as needed. Once it was working I started moving the various javascript functions into their own files to keep everything nice and neat. Then the problems started, mainly the map would not show up any more. So that was a pretty big problem. Luckily the fix was pretty simple, just move the dojo.addOnLoad line into it’s own script tag. If I had the dojo.addOnLoad in the same script block as the various require lines it would not work as expected. Works: <script type="text/javascript" language="javascript" src="javascript/test.js" />     <script type="text/javascript">       dojo.require("esri.map");       dojo.require("esri.tasks.locator");       dojo.require("esri.tasks.query");       dojo.require("esri.tasks.geometry");  </script>  <script type="text/javascript">      dojo.addOnLoad(init);  </script> Does not work: <script type="text/javascript" language="javascript" src="javascript/test.js" /> <script type="text/javascript">       dojo.require("esri.map");       dojo.require("esri.tasks.locator");       dojo.require("esri.tasks.query");       dojo.require("esri.tasks.geometry");       dojo.addOnLoad(init); </script> Technorati Tags: JavaScript,Dojo

• Basic is Best

  - by Eric A. Stephens

  Fellow foodies will recognize the recent movement towards "farm-to-table" restaurants. These venues attempt to simplify their menus and source ingredients as close to the source as possible. I had the opportunity to dine at such a restaurant the other evening. I was gushing about the appetizer to my server when she described the preparation for the item and then punctuated her comments with "basic is best". I reminded my fellow enterprise architect diners there was an architecture lesson in that statement. They rolled their eyes and chuckled. But they also knew I was right. I'm reminded of Frederick Brooks' book The Mythical Man Month and his latest The Design of Design. The former must read book talks about complexity. But he refrains from damning all complexity. The world we live in and enterprises we strive to transform with enterprise architecture are complicated organisms, much like the human body. But sometimes a simple solution is the best approach. Fewer applications (think: portfolio rationalization). Fewer components. Fewer lines of code. Whatever level of abstraction you are working at, less is more. I'm reminded of the enterprise architecture principle "Control Technical Diversity". At one firm I created pithy catch phrases for each principles. I named this one "Less is More". But perhaps another variation is what my server said the other night, "Basic is Best".

• What is a Coding Dojo?

  - by huwyss

  Recently i found out that there is a thing called "coding dojo". The point behind it is that software developers want to have a space to learn new stuff like processes, methods, coding details, languages, and whatnot in an environment without stress. Just for fun. No competition. No results required. No deadlines.Some days ago I joined the Zurich coding dojo. We were three programmers with different backgrounds.We gave ourselves the task to develop a method that takes an input value and returns its prime factors. We did pair programming and every few minutes we switched positions. We used test driven development. The chosen programming language was Ruby.I haven't really done TDD before. It was pretty interesting to see the algorithm develop following the testcases.We started with the first test input=1 then developed the most simple productive program that passed this very first test. Then we added the next test input=2 and implemented the productive code. We kept adding tests and made sure all tests are passed until we had the general solution.When we improved the performance of our code we saw the value of the tests we wrote before. Of course our first performance improvement broke several tests.It was a very interesting experience to see how other developers think and how they work. I will participate at the dojo again and can warmly recommend it to anyone. There are  coding dojos all over the world.Have fun!
