• Which one scales better asp or php?

  - by Marin

  Let's say the website is doing fine(forums,pictures,ajax). And it needs scaling up/scaling out. I feel more comfortable with php but I have worked with asp.net as well. Would you say asp.net is much more powerful, more robust and thus easier to scale out? What would be the pros and cons of converting the website to asp.net in regards to scalability and performance versus keeping the website written in PHP? Examples of personal experience in making such a conversion would be a plus. Thank you.

• Constructor should generally not call methods

  - by Stefano Borini

  I described to a colleague why a constructor calling a method can be an antipattern. example (in my rusty C++) class C { public : C(int foo); void setFoo(int foo); private: int foo; } C::C(int foo) { setFoo(foo); } void C::setFoo(int foo) { this->foo = foo } I would like to motivate better this fact through your additional contribute. If you have examples, book references, blog pages, or names of principles, they would be very welcome. Edit: I'm talking in general, but we are coding in python.

• Online Code Editor [closed]

  - by Velvet Ghost

  The major online IDEs are hosted on the service provider's server. Examples are Kodingen, Cloud9, ShiftEdit. Hence they would be unavailable if the external server was down for some reason, and I prefer to do my computing on my own computer anyway. Does anyone know of an online IDE or editor (preferably just an editor - a simple implementation of the Ace or CodeMirror JS editors) which can be downloaded and run on localhost (on a local LAMP server)? I've found two so far - Eclipse Orion and Wiode, but I don't like either of them very much, and I'm looking for alternatives. Also suitable are browser extensions which run natively on the browser (offline) without going to some external site. An example would be SourceKit for Chrom(e/ium).

• Active - like-minded Java mailing lists

  - by Lewis Robbins

  I need to find an active Java mailing list, I have looked onto the GNU Java mailing list, to my surprise there had been not too much activity this month, it also focused on any GNU related Java - I'd really help me progress my Java ability, if I had an active, likeminded Java mailing list. Questions' that are not suited to Stackoverflow, or provide little benefit to any user that see's the question: discussing a new API change; best practices; open source discussion; trivia type questions on Java ArrayList boxining-unboxing; Community atmosphere. I also read Jon Skeets blog post about his previous Java/C# mailing lists examples - I did not catch any names, though I did they would be of benefit to me, if I had access to any of them.

• Subdividing a polygon into boxes of varying size

  - by Michael Trouw

  I would like to be pointed to information / resources for creating algorithms like the one illustrated on this blog, which is a subdivision of a polygon (in my case a voronoi cell) into several boxes of varying size: http://procworld.blogspot.nl/2011/07/city-lots.html In the comments a paper by among others the author of the blog can be found, however the only formula listed is about candidate location suitability: http://www.groenewegen.de/delft/thesis-final/ProceduralCityLayoutGeneration-Preprint.pdf Any language will do, but if examples can be given Javascript is preferred (as it is the language i am currently working with) A similar question is this one: What is an efficient packing algorithm for packing rectangles into a polygon?

• When would you want two references to the same object?

  - by HCBPshenanigans

  In Java specifically, but likely in other languages as well; When would it be useful to have two references to the same object? Example: Dog a = new Dog(); Dob b = a; Is there a situation where this would be useful? Why would this be a preferred solution to using a whenever you want to interact with the object represented by a? Edit: Can I just say that all of your dog related examples are Delightful!

• Framework licensing question [closed]

  - by nosarious

  I have a framework I have been developing but find myself being unable to work on it over the next year. I would like to make it open source in the interim to get others to use it and improve how it works. I would like to consider a licensing system that allows for multiple instances of the software for singular users (ie, a newspaper/magazine or zine hosting the code on their own). I would like to limit it from becoming the basis of a larger hosting service right now because it is intended to be part of a much larger hosting ecosystem which allows for create and share their work. Right now there is no license associated with it, which is why I am not posting a link here. Any help or suggestion on how to handle licensing this code for contributions and use would be appreciated, and if anyone would like to see examples or the github I would be happy to send it.

• What does "GPL with classpath exception" mean in practice?

  - by Thilo

  Oracle seems to license all their Java-related open source code under the GPL with a classpath exception. From what I understand, this seems to allow to combine these libraries with your own code into products that do not have to be covered by the GPL. How does this work? What are examples of how I can and cannot use these classes? Why was this new license used as opposed to the LGPL, which seems to allow for pretty much the same things, but is better established and understood? What are the differences to the LGPL?

• Terminology For Web Development and General Programming/Software?

  - by Zenph

  EDIT: I should clarify. THe particular terms I listed below I fully understand. I also understand w3schools doesn't have the greatest information. These are just examples. I don't expect everybody to understand what an example is, but I hope the majority do. Does anybody have any resources listing terms related to programming and web development, or care to pitch in? Things like: Runtime Build time Framework Library Normalize I'm primarily a PHP developer so anything about that. I really am looking for general terms and specific terms related to web development, PHP, SQL, CSS, HTML. Appreciate any input. Couple I found: http://www.w3schools.com/site/site_glossary.asp http://docs.roxen.com/pike/7.0/tutorial/fundamentals/concepts.xml

• What is your most unusual javascript concept you've ever seen ?

  - by Cybrix

  Hi, I've learned javascript at school but since I'm working with it and study about it every day, I've found very particular aspect of javascript that I didn't know about. Which at first, was very hard to understand for me and finally, I found it very usefull and easy to implement. And in the final, it gives to my code some kind of "beauty". An example I've once seen: function getter( input ) { result = { foo1 : 'bar1', foo2 : 'bar2', foo3 : 'bar3' }[input] || input || "default"; return result; } Do you guys have other examples of particular use you make of Javascript ? Thank you PS: I use the term particular use because it might be unusual for any Javascript beginner. I believe this question is most likely to belong to the community wiki.

• On-Site Factors that Affect CPC

  - by ashes999

  I have a few websites on various niche topics, all running Adsense. The most promising one currently has a CPC that hovers around $1; the rest have CPCs of $0.25-$0.50. I'm curious to know what on-site factors affect CPC. That is to say, what I can do, legally (in white-hat compliance) to increase my CPC? Some factors that affect CPC but are not within my control (and therefore, beyond the scope of my question -- they're just examples) include: What advertisers are paying for keywords on my site What pages people are landing on etc.

• Render 3d object to 2d surface (embedded system)

  - by Martin Berger

  i am working on an embedded system of a sort, and in some free time i would like to test its drawing capabilities. System in question is ARM Cortex M3 microcontroller attached to EasyMX Stellaris board. And i have a small 320x240 TFT screen :) Now, i have some free time each day and i want to create rotating cube. Micro C PRO for ARM doesnt have 3d drawing capabilities, which means it must be done in software. From the book Introduction to 3D Game Programming with DirectX 10 i know matrix algebra for transformations but that is cool when you have DirectX to set camera right. I gues i could make 2d object to rotate, but how would i go with 3d one? Any ideas and examples are welcome. Although i would prefer advices. I'd like to understand this.

• Where can I get resources to design a website like this? [closed]

  - by Jhon Andrew

  I have a project. To make a CMS for an online game. Can anyone suggest me where I can get resources that I can use like vintage borders, seamless old papers or any vintage like patterns, etc. I would like to come up with something like this website for example: http://www.gamezaion.com/ I hope someone would suggest and/or give me ideas, inspirations, and examples how I can come up to something like it. P.S.: I am getting a hard time designing, because I define my self as a developer not a designer.. Lol.

• How well do free-to-open-source-projects policies work in practice?

  - by Steve314

  In comparison with an open source license and requesting donations, is a free-for-open-source-projects (or free for non-commercial developers) closed source and otherwise commercial project likely to get more license fees? Or just to alienate potential users? Assume the project has value to programmers - I'm looking for generalizations here, though specific examples comparing existing projects will be very interesting. What I have in mind involves code generating programming utilities. And one issue I can think of, either way, is a near total inability to enforce any license restrictions. After all, I can't go around the internet demanding that everyone show me their source code just in case!

• Help building pygtk application

  - by umpirsky

  This is my application. It is created with quickly. I would like to package it for Ubuntu now. I tried to package it with uickly, but that failed. At first, I was trying to install it using setup.py. But it is only copied in python lib dir, no icon, no desktop file installed. Then I tried to follow this guide, but I ended up with package without icon and it was of bad quality, but most important of all, it does not use setup.py, and it was pretty complicated. I would like to automate packaging process Can someone point me in the right direction, some examples of existing apps that have automated packaging etc? Thanks in advance.

• What are the most common stumbling blocks when it comes to learning programming, in order of difficulty?

  - by blueberryfields

  I seem to remember that linked lists, recursion, pointers, and memory management are all good examples of stumbling blocks - places where the aspiring programmer typically ends up spending significant time trying to understand a concept before moving on and improving, and many end up giving up and not improving. I'm looking for a complete/comprehensive list of these types of stumbling blocks, in rough estimated order of difficulty to learn, with the goal of making sure that an educational program for programmers is structured to properly guide students through them Is this information available somewhere? Ideally, the difficulty to learn will be measured in some sort of objective manner (ie, % of students which consistently fail to learn the concept) What sources are most appropriate for obtaining this information?

• What are your worst experiences with whitespace?

  - by CheeseConQueso

  What are some good examples of whitespace being the cause of any type of error and/or total disruption of scripts and/or markups? I am more interested in any accounts related to languages that are used commonly today, but I would like to hear about any cases in general. PS - This should be a wiki, but I don't know what happened to the "make this a wiki" check box. If someone comes across this with the rights to set it as a "wiki", please do so. If SO decided they wanted to keep away from wiki's altogether, please comment me about that. Thanks

• Using HTML entities in XML Literals (Avner Aharoni)

  One of the common use-cases of XML literals is creating HTML. However, HTML entities cannot be used in XML literals since LINQ to XML directly supports only the Data type definitions (DTD) defined in the XML 1.0 spec. You can read more about it here. The workaround is to use the Unicode representation of the entity, although its not as readable as the HTML entities, the output is the same. Here are two examples of HTML entities from the XHTML spec :   Entity...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• Recent Ubuntu update prevents MySQL root access

  - by Rhys

  I recently updated my Ubuntu (10.04 LTS) server (apt-get update, apt-get upgrade), and everything works fine, apart from the root access to my MySQL database. phpMyAdmin, CakePHP, and essentially all connections return similar access errors. For example, PMA returns 'Connection for controluser as defined in your configuration failed.' I have tried to find similar examples of this instance, but cannot find assistance in what configuration I should be changing to restore root log in access. The same issue has occurred on two servers. One has additional users so I could get around it, but the other is a new development server with only root MySQL access, so I am stuck on how to resolve this.

• Java EE@Princeton Java Meetup

  - by reza_rahman

  On November 28th, I spoke at the Princeton Java Meetup Group. It's a well-organized group led by veteran Java champion Yakov Fain - I have spoken there numerous times. I did my Java EE 6 DDD talk (the same one from Java2Days 2012). Domain Driven Design with Java EE 6 from Reza Rahman The code examples are available here: https://blogs.oracle.com/reza/resource/dddsample.zip. Give me a shout if you would like to get it up and running. The talk went very well -- the official RSVP shows 33 attended. I gave away a few GlassFish T-shirts, laptop stickers and Arun Gupta's Java EE 6 pocket guide. More details on the talk here. I most certainly look forward to speaking there again.

• Lean/Kanban *Inside* Software (i.e. WIP-Limits, Reducing Queues and Pull as Programming Techniques)

  - by Christoph

  Thinking about Kanban, I realized that the queuing-theory behind the SW-development-methodology obviously also applies to concurrent software. Now I'm looking for whether this kind of thinking is explicitly applied in some area. A simple example: We usually want to limit the number of threads to avoid cache-thrashing (WIP-Limits). In the paper about the disruptor pattern[1], one statement that I found interesting was that producer/consumers are rarely balanced so when using queues, either consumers wait (queues are empty), or producers produce more than is consumed, resulting in either a full capacity-constrained queue or an unconstrained one blowing up and eating away memory. Both, in lean-speak, is waste, and increases lead-time. Does anybody have examples of WIP-Limits, reducing/eliminating queues, pull or single piece flow being applied in programming? http://disruptor.googlecode.com/files/Disruptor-1.0.pdf
