• printable PHP manual - 'all but the Function Reference section'

  - by JW01

  My Motivation I find it easier to learn things by reading 'offline'. I'd like to lean back and read the narrative part of a paper version of the official php manual. My Scuppered Plan My plan was to download the manual, print all but the Function Reference section and then read it. I have downloaded the "Single HTML file" version of the manual from the php.net download page. (That version did not contain any images, so I patched-in the ones from the Many HTML files version with no problem.) My plan was to open that "Single HTML file" in an HTML editor, delete the Function Reference section then print it out. Unfortunately, although I have tried three different editors, I have not been able to successfully load-up that massive html file to be able to edit it. Its about (~40MB). I started to look into the phpdoc framework with a view to rendering my own html docs from the source...but that's a steep learning curve for a newby..and is a last resort. I would use a file splitter, but they tend to split files crudely with no regard for html/xml/xhtml sematics. So the question is... Does anyone know know where you can download the php manual in a version that is a kind of half-way house between the 'Single HTML file' and the 'Many HTML files'? Ideally with the docs split into 3 parts: File 1 - stuff before the function reference File 2 - function reference File 3 - stuff after the function reference Or Can you suggest any editors/tools will enable me to split up this file myself?

• Thoughts on my new template language?

  - by Ralph

  Let's start with an example: using "html5" using "extratags" html { head { title "Ordering Notice" jsinclude "jquery.js" } body { h1 "Ordering Notice" p "Dear @name," p "Thanks for placing your order with @company. It's scheduled to ship on {@ship_date|dateformat}." p "Here are the items you've ordered:" table { tr { th "name" th "price" } for(@item in @item_list) { tr { td @item.name td @item.price } } } if(@ordered_warranty) p "Your warranty information will be included in the packaging." p(class="footer") { "Sincerely," br @company } } } The "using" keyword indicates which tags to use. "html5" might include all the html5 standard tags, but your tags names wouldn't have to be based on their HTML counter-parts at all if you didn't want to. The "extratags" library for example might add an extra tag, called "jsinclude" which gets replaced with something like <script type="text/javascript" src="@content"></script> Tags can be optionally be followed by an opening brace. They will automatically be closed as the closing brace. If no brace is used, they will be closed after taking on element. Variables are prefixed with the @ symbol. They may be used inside double-quoted strings. I think I'll use single-quotes to indicate "no variable substitution" like PHP does. Filter functions can be applied to variables like @variable|filter. Arguments can be passed to the filter @variable|filter:@arg1,arg2="y" Attributes can be passed to tags by including them in (), like p(class="classname"). Some questions: Which symbol should I use to prefix variables? @ (like Razor), $ (like PHP), or something else? Should the @ symbol be necessary in "for" and "if" statements? It's kind of implied that those are variables. Tags and controls (like if,for) presently have the exact same syntax. Should I do something to differentiate the two? If so, what? Do you like the attribute syntax? (round brackets) I'll add more questions in a few minutes, once I get some feedback.

• Design considerations on JSON schema for scalars with a consistent attachment property

  - by casperOne

  I'm trying to create a JSON schema for the results of doing statistical analysis based on disparate pieces of data. The current schema I have looks something like this: { // Basic key information. video : "http://www.youtube.com/watch?v=7uwfjpfK0jo", start : "00:00:00", end : null, // For results of analysis, to be populated: // *** This is where it gets interesting *** analysis : { game : { value: "Super Street Fighter 4: Arcade Edition Ver. 2012", confidence: 0.9725 } teams : [ { player : { value : "Desk", confidence: 0.95, } characters : [ { value : "Hakan", confidence: 0.80 } ] } ] } } The issue is the tuples that are used to store a value and the confidence related to that value (i.e. { value : "some value", confidence : 0.85 }), populated after the results of the analysis. This leads to a creep of this tuple for every value. Take a fully-fleshed out value from the characters array: { name : { value : "Hakan", confidence: 0.80 } ultra : { value: 1, confidence: 0.90 } } As the structures that represent the values become more and more detailed (and more analysis is done on them to try and determine the confidence behind that analysis), the nesting of the tuples adds great deal of noise to the overall structure, considering that the final result (when verified) will be: { name : "Hakan", ultra : 1 } (And recall that this is just a nested value) In .NET (in which I'll be using to work with this data), I'd have a little helper like this: public class UnknownValue<T> { T Value { get; set; } double? Confidence { get; set; } } Which I'd then use like so: public class Character { public UnknownValue<Character> Name { get; set; } } While the same as the JSON representation in code, it doesn't have the same creep because I don't have to redefine the tuple every time and property accessors hide the appearance of creep. Of course, this is an apples-to-oranges comparison, the above is code while the JSON is data. Is there a more formalized/cleaner/best practice way of containing the creep of these tuples in JSON, or is the approach above an accepted approach for the type of data I'm trying to store (and I'm just perceiving it the wrong way)? Note, this is being represented in JSON because this will ultimately go in a document database (something like RavenDB or elasticsearch). I'm not concerned about being able to serialize into the object above, because I can always use data transfer objects to facilitate getting data into/out of my underlying data store.

• Extracting data from internet

  - by Ankiov Spetsnaz

  I would like to extract data from internet like www.mozenda.com does but I want to write my own program to do that. Specific data I'm looking for is various event data. Based on my research, I think custom web crawler is my answer but I Would like to confirm the answer and see if there are any suggestion to make custom web crawlers if web crawler indeed is an answer. Personally, I would prefer Java and I'm planning on using Glassfish technology if that matters...

• Adaptative interface with Open GL and machine learning in C#

  - by Afnan

  For my Semester project I have to go for any Adaptative Interface Design. My language is C# and I have to Use OpenTK (wrapper for OpenGL). I have an idea that I should show two points and some obstacles and my subject (user) would drag an object from one place to the final place avoiding the Obstacles. Also (s)he can place obstacles randomly. My software should be able to learn some paths by doing test runs and then after learning it should be able to predict the shortest path. I do not know how stupid this idea sounds but it is just an idea. I need help regarding any ideas for adaptative interface possible small projects or if my idea is ok then please can you tell me what should be used to implement it? I mean that along with OpenGl for the Graphics what can I use for machine learning?

• Is inline SQL still classed as bad practice now that we have Micro ORMs?

  - by Grofit

  This is a bit of an open ended question but I wanted some opinions, as I grew up in a world where inline SQL scripts were the norm, then we were all made very aware of SQL injection based issues, and how fragile the sql was when doing string manipulations all over the place. Then came the dawn of the ORM where you were explaining the query to the ORM and letting it generate its own SQL, which in a lot of cases was not optimal but was safe and easy. Another good thing about ORMs or database abstraction layers were that the SQL was generated with its database engine in mind, so I could use Hibernate/Nhibernate with MSSQL, MYSQL and my code never changed it was just a configuration detail. Now fast forward to current day, where Micro ORMs seem to be winning over more developers I was wondering why we have seemingly taken a U-Turn on the whole in-line sql subject. I must admit I do like the idea of no ORM config files and being able to write my query in a more optimal manner but it feels like I am opening myself back up to the old vulnerabilities such as SQL injection and I am also tying myself to one database engine so if I want my software to support multiple database engines I would need to do some more string hackery which seems to then start to make code unreadable and more fragile. (Just before someone mentions it I know you can use parameter based arguments with most micro orms which offers protection in most cases from sql injection) So what are peoples opinions on this sort of thing? I am using Dapper as my Micro ORM in this instance and NHibernate as my regular ORM in this scenario, however most in each field are quite similar. What I term as inline sql is SQL strings within source code. There used to be design debates over SQL strings in source code detracting from the fundamental intent of the logic, which is why statically typed linq style queries became so popular its still just 1 language, but with lets say C# and Sql in one page you have 2 languages intermingled in your raw source code now. Just to clarify, the SQL injection is just one of the known issues with using sql strings, I already mention you can stop this from happening with parameter based queries, however I highlight other issues with having SQL queries ingrained in your source code, such as the lack of DB Vendor abstraction as well as losing any level of compile time error capturing on string based queries, these are all issues which we managed to side step with the dawn of ORMs with their higher level querying functionality, such as HQL or LINQ etc (not all of the issues but most of them). So I am less focused on the individual highlighted issues and more the bigger picture of is it now becoming more acceptable to have SQL strings directly in your source code again, as most Micro ORMs use this mechanism. Here is a similar question which has a few different view points, although is more about the inline sql without the micro orm context: http://stackoverflow.com/questions/5303746/is-inline-sql-hard-coding

• Is Information Technology really Engineering?

  - by RPK

  While travelling I met a mathematician who was sitting near me. In a discussion he said: "...there is nothing like engineering in IT or rather programming". A true engineering is what Architecture is, what Electrical and Mechanical is. It made me think and I was puzzled. A percent of my brain agreed also because in Indian Army, there is no subject like Computer Engineering in the Engineering Corps. They don't consider programming as engineering. This is what I heard few years back, I don't know what Indian Army thinks now. What are your views?

• Using old code on new version of Visual Studio [migrated]

  - by Tu Tran

  I have a project which was started from 90s in C/C++. Therefore, it contains many old coding styles such as K&R-style function declaration, obsolete function, ... The project works fine in Visual Studio 2008, but now I want to use it in the new version of Visual Studio (specifically VS 2010) because we have other projects in Visual Studio 2010/2012. I don't want to have too many versions of Visual Studio on my machine. When I try to compile the old project, Visual Studio throws too many errors. I can fix all of them but I am scared to edit the source code and I want other people to be able to pen it in the old version of VS too. I want the project to remain backwards compatible with VS. My question is how to use the old code in Visual Studio 2010/2012 without changing the code. Or if necessary how do I just fix a few lines of code, but make sure it won't cause an error if someone else opens that code in the older version of VS. Is there a way to tell newer Visual Studio versions to use older compiler flags or something like that?

• What are the leading professional journals in software development?

  - by Austin Hyde

  In one of my classes, we were asked to research the top professional journals in our field. According to what I can dig up, the ACM and IEEE journals are the "best", as they come up at the top of my searches and this question. However, there are a dozen or so individually topic-ed journals for each, with no very clear measure of which one is most useful, popular, etc. For example, "IEEE Software" vs. "IEEE Transactions on Software Engineering". So, what do you consider to be the "leading" professional journals (specifically), and why? It doesn't have to be only ACM or IEEE, either. If you know of another, please add it.

• Teamwork 101 for the solo newbie

  - by clankercrusher

  Forgive my newbishness but I have a question to ask about teamwork...mainly because I stink at it. Most of my projects up until this point have been solo so I have a very limited experience with teamwork. I did make graphics for a game that was being developed by several people, but that was completely different than programming with several different people. Right now I'm working with someone else on an indie MMO along with a few other team members. I've already made some pretty stupid mistakes, (like rewriting EVERYTHING) so I have two questions for you guys: 1) What are some of the most common mistakes that people make in a team environment and how can they be avoided? 2) How can the structure of your program be altered to allow for multiple teams members to work on different parts of the program at the same time? P.S. Is this the right stack exchange site for this type of question? (if not, where does it go? Thanks)

• What are the options for simple Ajax calls for a Java webapp?

  - by Cedric Martin

  I've got a very simple need and I don't know what are the options available. If I simplify, users see webpage like this server by a Java webapp server: [-] red [x] green [-] blue [-] yellow The selected color is green And then I want the user to be able to select the yellow color and have the part of the page containing the relevant text change to: [-] red [-] green [-] blue [x] yellow The selected color is yellow Basically I want something a bit more user friendly than simply using HTTP GET all the time. There shall be a lot of options the user can select from and this shall affect an (HTML formatted) text displayed on the page. And I want the user to see his change as soon as possible, without having the page to fully reload and without being redirected to another page. There shall be a client/server round-trip (the information to display depending on the options selected ain't available on the client-side so I cannot do it all in JavaScript in the browser). I'd like to use Ajax requests but I don't know which way to go: jQuery GWT something else What are my options and what would be the pros and cons of the various approach? P.S: I'm very familiar with Java (SCP since the last century and basically being a Java programmer for the last 12 years or so) but not familiar at all with JavaScript (though I did hack a few Ajaxy-calls years ago, way before great libraries existed).

• Overview of getting and setting the URL and parts of the URL using angularjs and/or Javascript

  - by Sandy Good

  Getting and Setting the URL, and different parts of the URL are a basic part of Application Design. For Page Navigation Deep Linking Providing a link to the user Querying Data Passing information to other pages Both angularjs and javascript provide ways to get/set the URL and parts of the URL. I'm looking for the following information: Situation: Show a simple URL in the browser address bar to the user Provide a more detailed URL with string parameters to the page that the user will not see. In other words, two different URLs will be used, one simple one that the user sees in the browser, a more detailed one available to the page on load. Get URL info with PHP when then page intially loads, both don't reload the PHP page when the user needs more detailed info that is already loaded but not displayed yet. Set the URL with a more detailed URL for deep linking as the user drills down to more specific information. Get URL info in a controller or JavaSript when angularjs detects a change in the URL with routing. Hash or Query String or Both? Should I use a hash # in the URL, a string ?= or both? Here is what I currently know and what I want: A Query String HTTP:\\www.name.com?mykey=itemID will prevent angularjs from reloading the page. So, I can change the URL by adding/changing the string at the end, thereby providing new info to the page, and keep the page from reloading. I can change the URL and force a page reload with: window.location.href = "#Store/" + argUserPubId + "?itemID=home"; If home is the itemID string, I want code to simply load the page, and not display more detailed information. If there is a real itemID in the URL query string, I want the code to display the more detailed information. Code from angularjs will run either from the controller specified in the routing, or a controller specified in the HTML, or both. The angularjs code specified in the routing seems to run first, before the code specified in the HTML. A different URL for the page can be used in angularjs templateURL: than the URL that was sent to the browser address bar. when('/Store/:StoreId', { templateUrl: function(params){return 'Client_Pages/Stores.php?storeID=' + params.StoreId;}, controller: 'storeParseData' }). The above code detects http:\\www.name.com\Store\StoreID in the browser, but SENDS http:\\www.name.com\Client_Pages/Stores.php?storeID=StoreID to the page. In the above code, a function is used for the angularjs routing templateURL: to dynamically set the templateURL. So, when the user clicks something to see details of an item, how should I configure the URL? Should I use angularjs $location or window.location.href ? Should I use a longer URL with more parameters, a hash bang, or a query string? Should I use: http:\\www.name.com\Store\StoreID\ItemID or http:\\www.name.com\Store\StoreID#ItemID or http:\\www.name.com\Store\StoreID?ItemID or http:\\www.name.com\Store#StoreID?ItemID or Something else?

• Why do you need float/double?

  - by acidzombie24

  I was watching http://www.joelonsoftware.com/items/2011/06/27.html and laughed at Jon Skeet joke about 0.3 not being 0.3. I personally never had problems with floats/decimals/doubles but then I remember I learned 6502 very early and never needed floats in most of my programs. The only time I used it was for graphics and math where inaccurate numbers were ok and the output was for the screen and not to be stored (in a db, file) or dependent on. My question is, where are places were you typically use floats/decimals/double? So I know to watch out for these gotchas. With money I use longs and store values by the cent, for speed of an object in a game I add ints and divide (or bitshift) the value to know if I need to move a pixel or not. (I made object move in the 6502 days, we had no divide nor floats but had shifts). So I was mostly curious.

• PHP Aspect Oriented Design

  - by Devin Dixon

  This is a continuation of this Code Review question. What was taken away from that post, and other aspect oriented design is it is hard to debug. To counter that, I implemented the ability to turn tracing of the design patterns on. Turning trace on works like: //This can be added anywhere in the code Run::setAdapterTrace(true); Run::setFilterTrace(true); Run::setObserverTrace(true); //Execute the functon echo Run::goForARun(8); In the actual log with the trace turned on, it outputs like so: adapter 2012-02-12 21:46:19 {"type":"closure","object":"static","call_class":"\/public_html\/examples\/design\/ClosureDesigns.php","class":"Run","method":"goForARun","call_method":"goForARun","trace":"Run::goForARun","start_line":68,"end_line":70} filter 2012-02-12 22:05:15 {"type":"closure","event":"return","object":"static","class":"run_filter","method":"\/home\/prodigyview\/public_html\/examples\/design\/ClosureDesigns.php","trace":"Run::goForARun","start_line":51,"end_line":58} observer 2012-02-12 22:05:15 {"type":"closure","object":"static","class":"run_observer","method":"\/home\/prodigyview\/public_html\/public\/examples\/design\/ClosureDesigns.php","trace":"Run::goForARun","start_line":61,"end_line":63} When the information is broken down, the data translates to: Called by an adapter or filter or observer The function called was a closure The location of the closure Class:method the adapter was implemented on The Trace of where the method was called from Start Line and End Line The code has been proven to work in production environments and features various examples of to implement, so the proof of concept is there. It is not DI and accomplishes things that DI cannot. I wouldn't call the code boilerplate but I would call it bloated. In summary, the weaknesses are bloated code and a learning curve in exchange for aspect oriented functionality. Beyond the normal fear of something new and different, what are other weakness in this implementation of aspect oriented design, if any? PS: More examples of AOP here: https://github.com/ProdigyView/ProdigyView/tree/master/examples/design

• What functionality does dynamic typing allow?

  - by Justin984

  I've been using python for a few days now and I think I understand the difference between dynamic and static typing. What I don't understand is under what circumstances it would be preferred. It is flexible and readable, but at the expense of more runtime checks and additional required unit testing. Aside from non-functional criteria like flexibility and readability, what reasons are there to choose dynamic typing? What can I do with dynamic typing that isn't possible otherwise? What specific code example can you think of that illustrates a concrete advantage of dynamic typing?

• Mirror virtualized development environment

  - by David Casillas

  I work alone in some iOS projects in a local environment. I have been thinking in a way to be able to share my development environment between my Mac Mini and my MacBook. I mostly work at home in the Mini but sometimes I need to do a demo or work outside and I would like to have the development environment mirrored in both. I have think in using a virtual machine (via VirtualBox) with just my development tools instaled. Then I could synchronize that VM with some software between both computers so I will always have the exact environment no matter what computer I use. Is there any good reason not do do this way? I have not used Virtualization to much so I have no background on the subject. My basic setup will be: Mac Mini: i7 dual Core, 8Gb. OSX Mountain Lion Host OS: MacBook: 2.4 Core 2 Duo. 4Gb. OSX Lion Host OS. Virtual Box with Mountain Lion guest OS in both machines. XCode5, Simulator.

• What micro web-framework has the lowest overhead but includes templating

  - by Simon Martin

  I want to rewrite a simple small (10 page) website and besides a contact form it could be written in pure html. It is currently built with classic asp and Dreamweaver templates. The reason I'm not simply writing 10 html pages is that I want to keep the layout all in 1 place so would need either includes or a masterpage. I don't want to use Dreamweaver templates, or batch processing (like org-mode) because I want to be able to edit using notepad (or Visual Studio) because occasionally I might need to edit a file on the server (Go Daddy's IIS admin interface will let me edit text). I don't want to use ASP.NET MVC or WebForms (which I use in my day job) because I don't need all the overhead they bring with them when essentially I'm serving up 9 static files, 1 contact form and 1 list of clubs (that I aim to use jQuery to filter). The shared hosting package I have on Go Daddy seems to take a long time to spin up when serving aspx files. Currently the clubs page is driven from an MS SQL database that I try to keep up to date by manually checking the dojo locator on the main HQ pages and editing the entries myself, this is again way over the top. I aim to get a text file with the club details (probably in JSON or xml format) and use that as the source for the clubs page. There will need to be a bit of programming for this as the HQ site is unable to provide an extract / feed so something will have to scrape the site periodically to update my clubs persistence file. I'd like that to be automated - but I'm happy to have that triggered on a visit to the clubs page so I don't need to worry about scheduling a job. I would probably have a separate process that updates the persistence that has nothing to do with the rest of the site. Ideally I'd like to use Mercurial (or git) to publish, I know Bitbucket (and github) both serve static page sites so they wouldn't work in this scenario (dynamic pages and a contact form) but that's the model I'd like to use if there is such a thing. My requirements are: Simple templating system, 1 place to define header, footers, menu etc., that can be edited using just notepad. Very minimal / lightweight framework. I don't need a monster for 10 pages Must run either on IIS7 (shared Go Daddy Windows hosting) or other free host

• What's the benefit of object-oriented programming over procedural programming?

  - by niko

  I'm trying to understand the difference between procedural languages like C and object-oriented languages like C++. I've never used C++, but I've been discussing with my friends on how to differentiate the two. I've been told C++ has object-oriented concepts as well as public and private modes for definition of variables: things C does not have. I've never had to use these for while developing programs in Visual Basic.NET: what are the benefits of these? I've also been told that if a variable is public, it can be accessed anywhere, but it's not clear how that's different from a global variable in a language like C. It's also not clear how a private variable differs from a local variable. Another thing I've heard is that, for security reasons, if a function needs to be accessed it should be inherited first. The use-case is that an administrator should only have as much rights as they need and not everything, but it seems a conditional would work as well: if ( login == "admin") { // invoke the function } Why is this not ideal? Given that there seems to be a procedural way to do everything object-oriented, why should I care about object-oriented programming?

• What strategies you followed to keep your programming skills fresh during a long break?

  After being away from development for more than a year, I find it challenging to join back the work force, and I can feel the rustiness. I wonder what you have done to either keep your skills fresh during such periods or how you gained back the skills you might have forgotten? I understand coding is a great way to become more competent, but how do you start getting more involved in it while you are not working as a developer?

• Exception Handling Frequency/Log Detail

  - by Cyborgx37

  I am working on a fairly complex .NET application that interacts with another application. Many single-line statements are possible culprits for throwing an Exception and there is often nothing I can do to check the state before executing them to prevent these Exceptions. The question is, based on best practices and seasoned experience, how frequently should I lace my code with try/catch blocks? I've listed three examples below, but I'm open to any advice. I'm really hoping to get some pros/cons of various approaches. I can certainly come up with some of my own (greater log granularity for the O-C approach, better performance for the Monolithic approach), so I'm looking for experience over opinion. EDIT: I should add that this application is a batch program. The only "recovery" necessary in most cases is to log the error, clean up gracefully, and quit. So this could be seen to be as much a question of log granularity as exception handling. In my mind's eye I can imagine good reasons for both, so I'm looking for some general advice to help me find an appropriate balance. Monolitich Approach class Program{ public static void Main(){ try{ Step1(); Step2(); Step3(); } catch (Exception e) { Log(e); } finally { CleanUp(); } } public static void Step1(){ ExternalApp.Dangerous1(); ExternalApp.Dangerous2(); } public static void Step2(){ ExternalApp.Dangerous3(); ExternalApp.Dangerous4(); } public static void Step3(){ ExternalApp.Dangerous5(); ExternalApp.Dangerous6(); } } Delegated Approach class Program{ public static void Main(){ try{ Step1(); Step2(); Step3(); } finally { CleanUp(); } } public static void Step1(){ try{ ExternalApp.Dangerous1(); ExternalApp.Dangerous2(); } catch (Exception e) { Log(e); throw; } } public static void Step2(){ try{ ExternalApp.Dangerous3(); ExternalApp.Dangerous4(); } catch (Exception e) { Log(e); throw; } } public static void Step3(){ try{ ExternalApp.Dangerous5(); ExternalApp.Dangerous6(); } catch (Exception e) { Log(e); throw; } } } Obsessive-Compulsive Approach class Program{ public static void Main(){ try{ Step1(); Step2(); Step3(); } finally { CleanUp(); } } public static void Step1(){ try{ ExternalApp.Dangerous1(); } catch (Exception e) { Log(e); throw; } try{ ExternalApp.Dangerous2(); } catch (Exception e) { Log(e); throw; } } public static void Step2(){ try{ ExternalApp.Dangerous3(); } catch (Exception e) { Log(e); throw; } try{ ExternalApp.Dangerous4(); } catch (Exception e) { Log(e); throw; } } public static void Step3(){ try{ ExternalApp.Dangerous5(); } catch (Exception e) { Log(e); throw; } try{ ExternalApp.Dangerous6(); } catch (Exception e) { Log(e); throw; } } } Other approaches welcomed and encouraged. Above are examples only.

• Expected sprint completion rate and load in scrum?

  - by bjarkef

  Recently at work there have been increased focus on completion rate and load on the developers in our sprints. With completion rate I mean, if we plan 20 user stories for a sprint, what percentage of these user stories are closed at the end of the sprint. And with load I mean, if we have a sprint with 3 developers of 60 hours each, i.e. 180 hours for the sprint, how many hours worth of user stories do we schedule for the sprint. So I am really interested in others experience with this, I guess this is something everybody working with scrum deals with. My question is, what completion rate and load are expected/usual, and how are your team doing with respect to these parameters?

• Does the use of mongodb it easier to extend/change database driven applications?

  - by developer10214

  When an application is created which need to store data, an SQL database is used very often. So did I in a lot of asp.net applications. The resulting applications have often an ORM like the entity framework and maybe a business layer. So when such an application needs to be extended(let's say you have to add a comment property to an object), you have to change/extend the database, then the ORM and the business layer and so on. To deploy the changes you have to update the target database and the application. I know that things like code first and fluent can make this approach easier. I tried mongodb, I only used the standard driver and I had to extend some objects and all I had to do was changing the code. So it feels that such approaches are much easier to realize when using mongodb. I don't have much experience with larger applications an mongodb. I know that a SQL database or mongodb doesn't fit for all needs and both have their pros and cons. I want to know if my feeling is right, if yes I would choose rather choose mongodb than SQL database.

• Why did Apple remove Python support in Mavericks, aka Mac OS X 10.9?

  - by alex gray

  Apple has removed Python support (at least on the Developer level) in 10.9. Python IS still on the machine in /System/Library/Frameworks/Python.framework... but trying to link to Python using the 10.9 SDK fails. /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/System/Library/Frameworks does not have Python. I'm not a Pythonista, but find it interesting that Apple has made this change. I don't understand why this is done and I'm a bit annoyed that I have to remove Python from my compilation units in order to compile with 10.9 SDK. Is this a statement by Apple, along the lines of "People aren't using Python very much anymore so we're going to phase out support"? Or was something else driving the change?
