• Why am I getting messages from cloudfront in my error log?

  - by JK01

  I frequently have messages like this in my websites error log: "Script error.". URL: https://e3m4drct5m1ays.cloudfront.net/items/loaders /loader_21.js?pid=21&systemid=13504281c5a501837196c23300f84e66&aoi=1327214632& zoneid=16620&cid=HK&rid=Hong%20Kong%20(general)&ccid=Kowloon&dma=0. Line number: 0 Error name: Stack: Now I don't actually know what cloudfront is or what it does. And I do not refer to this script in my site. So why would I be getting js error logged as if it was a script being run on my own site? This is using elmah logging.

• What are my options for selling software independently on Windows?

  - by technomalogical

  I am looking to port a tool from the Mac app store over to Windows, the platform where I spend most of my time these days. I've spoken with the author of the original app and we've begun talking about licensing options should I decide to sell the application, and it seems like it would be feasible. I've never sold software independently, let alone on Windows. That I know of, there is not (yet) an equivalent app store for Windows (maybe one coming with Windows 8). Assuming my product was done today and I was ready to go to market, what options do I have for selling software for Windows as an independent developer or Micro-ISV? I know can sell it through my own website and accept PayPal, but are there options that will offer more visibility, similar to that of the Apple app stores? Any options to avoid?

• Skeletal Animation - Automatically apply skeleton to model

  - by Randomman159

  Looking at websites such as mixamo.com or some game's development systems such as the animation editor for Overgrowth (http://www.youtube.com/watch?v=-RpqbC5-Z0E), i see that the skeleton in these situations is automatically being applied to the models. I really don't expect (though wouldn't mind) code that does this, but i really am looking for some sort of pointer in the direction, or how they go about this. If any of you have done this, or know how to, please do reply, i don't want to spend the next week trying to crack it, then another to actually code it :P Thanks all :) Just for a bit more information, i am in C# working with OpenTK with my own custom model loader, etc. but i can easily adjust any given code / concept to fit with mine :)

• How to Name Groups of Apps on the Windows 8 Metro Start Screen

  - by Taylor Gibb

  The Windows 8 Start Screen certainly takes some getting use to, however, one of the things that I really miss about the Start Menu was how i was able to categorize my installed applications. While you cant create folders on the Start Screen, you can group your applications. To get started head over to the Metro Start Screen and move your mouse to the bottom right-hand corner, clicking on the small icon. Now right click on the group of apps that you want to name.

• Prevent APT from overwriting JCE jars

  - by Doc

  My server runs a Java application that requires I replace a few java library files with ones I downloaded on my own. This has to do with JCE security extensions and isn't really relevant to my question. I've found that these library files tend to get overwritten by apt when it later updates my java package. Is there a apt-friendly way of masking these specific files so apt won't touch them? Potential Solutions I'm considering just removing the write flag from the files, though I'm expecting this will cause apt to spew its guts everywhere when it later tries to overwrite them? Perhaps there's a java custom library directory I don't know of, where I can park my files and they'll be loaded instead of the package's defaults? The last-resort option I'm considering is writing a cron job to periodically replace the files with my versions. I hate this option.

• Best book for developer who needs to learn software fundamentals

  - by tharrison

  I have recently inherited a team of developers, none of whom really have any programming experience. Some are really bright, and are learning on their own. I am looking for one or two books that are practical but show the core practices of professional development: Structure, OO, naming, DRY, why elegance matters, etc. When I was learning, I loved Code Complete, and Programming Pearls, but they are dated now. Any recommendations for good books that could be used in tandem with a language specific book to help understand? Thanks in advance!

• Adaptive Characters: AI Solution Needs a Problem

  - by Roger F. Gay

  Have sophisticated adaptive programming, will travel - so to speak. I'm part of a group that developed sophisticated learning / adaptive software for robotics. The system "thinks" via its simulator, building and adapting code on its own; and then carries out the best solution. The software can also adapt to new situations, etc. http://mensnewsdaily.com/2007/05/16/robobusiness-robots-with-imagination/ It's easy to imagine using it with automated game characters that will adapt to the players moves and style - the easiest example would be fighting. The more the simulated fighter fights with the human player, the more it learns to counter that players fighting skills. But there should be more. Anyone have any ideas as to how adaptive characters might be interesting in games?

• How can I ensure our project gets developed successfully, without having any project management experience? [migrated]

  - by Raven13

  I'm a web developer who is part of a three-man team that has been tasked with a rather large and complex development project. Other than some direction and impetus from management, we're pretty much on our own to develop the new website. None of us have any project management experience nor do my two coworkers seem like they would be interested in taking on that role, so I feel like it's up to me to implement some kind of structure to the development process in order to avoid issues down the road. What can I do as a developer without project management experience to ensure that our project gets developed successfully and avoid the pitfalls of developing a project without a plan?

• Recommendation for Improving Programming Skills

  - by Moaz ELdeen

  I'm 25, I know C++ syntax since 9 years.. but It seems that I have copied so much code, and I didn't learn that much and didn't solve a lot of algorithms in my own. Currently I'm working for computer vision programmer as a junior and I have difficulity of doing algorithms like blob tracking or object tracking, writing algorithms like KNN, Quadtree,..etc. I don't know what to do, or what to improve, I tried to write asteriods game, I have finished it, and here you can watch it https://www.youtube.com/watch?v=jw0L4aCB4TU What should I do more to enhance my skills ?

• One True Event Loop

  - by CyberShadow

  Simple programs that collect data from only one system need only one event loop. For example, Windows applications have the message loop, POSIX network programs usually have a select/epoll/etc. loop at their core, pure SDL games use SDL's event loop. But what if you need to collect events from several subsystems? Such as an SDL game which doesn't use SDL_net for networking. I can think of several solutions: Polling (ugh) Put each event loop in its own thread, and: Send messages to the main thread, which collects and processes the events, or Place the event-processing code of each thread in a critical section, so that the threads can wait for events asynchronously but process them synchronously Choose one subsystem for the main event loop, and pass events from other subsystems via that subsystem as custom messages (for example, the Windows message loop and custom messages, or a socket select() loop and passing events via a loopback connection). Option 2.1 is more interesting on platforms where message-passing is a well-developed threading primitive (e.g. in the D programming language), but 2.2 looks like the best option to me.

• Learning Programming, Suggestions for a roadmap

  - by RisingSun

  Hi, Some background first- I am new to programming and have discovered it rather late in life; Like many hobbyists, my introduction to the subject has been through php/jquery (yes, i know the popular mood around here... they-are-not-real-programminng-languages ;-) ). I like to believe that I am reasonably competent at what I do in my other life and this developing addiction to coding has taken a very heavy toll on my professional prospects. This is the question: What programming languages next? (No plans to ditch php in the immediate future, that will involve rewriting much of my code) Any absolutely essential books I must read? Is it necessary to join a college/university course? Do I need to ditch my other profession to continue serious learning? My goals are: Develop a solid understanding of the science and art of programming. Continue to work on my own web application (Hands on learning suits me best) I am something of a generalist interested in everything from UI to database performance

• AngularJS: structuring a web application with multiple ng-apps

  - by mg1075

  The blogosphere has a number of articles on the topic of AngularJS app structuring guidelines such as these (and others): http://www.johnpapa.net/angular-app-structuring-guidelines/ http://codingsmackdown.tv/blog/2013/04/19/angularjs-modules-for-great-justice/ http://danorlando.com/angularjs-architecture-understanding-modules/ http://henriquat.re/modularizing-angularjs/modularizing-angular-applications/modularizing-angular-applications.html However, one scenario I have yet to come across for guidelines and best practices is the case where you have a large web application containing multiple "mini-spa" apps, and the mini-spa apps all share a certain amount of code. I am not referring to the case of trying to have multiple ng-app declarations on the same page; rather, I mean different sections of a large site that have their own, unique ng-app declaration. As Scott Allen writes in his OdeToCode blog: One scenario I haven't found addressed very well is the scenario where multiple apps exist in the same greater web application and require some shared code on the client. Are there any recommended approaches to take, pitfalls to avoid, or good sample structures of this scenario that you can point to?

• How do I get Paypal or a merchant account for a marketplace style web site?

  - by Brett G

  I'm having trouble getting approved for a merchant account for my website. Basically I have expert users and users. Expert users provide a service through my website which they set their own rates. Users purchase the services, then pay me, I give 90% to the expert users. I have been told this is factoring.. Is the way around this, a system like freelancer.com does? Where users deposit money into their freelancer account, then pay for the services they won? What are the negatives to this system? What about sites like 99designs? They accept CC payments and then pay the winning designer. How are some sites doing this but I'm having so much trouble getting approved?

• How do you off load work from the database?

  - by TheLQ

  In at least the web development field, web servers are everywhere but are backed by very few database servers. As web servers get hit with requests they execute large queries on the database, putting the server under heavy load. While web servers are very easy to scale, db servers are much harder (at least from what I know), making them a precious resource. One way I've heard from some answers here to take load off the database is to offload the work to the web server. Easy, until you realize that now you've got a ton of traffic internally as a web server tries to run SELECT TOP 3000 (presumably to crunch the results on its own), which still slows things down. What are other ways to take load off the database?

• Why should I adopt MVC?

  - by Andrew

  I decided to get my hands wet and got the YII framework for PHP. I created my first application, then created new controller, model and view. Connected to database, got my record passed from controller to the view and printed the hello world. I am confused now. If I have to do the same thing for each page, this seems like a nightmare to me. In each controller I have to do a lot of same operations - declare variables, and pass them to views. I also need to create models for each page and this is all confusing to me. In my idea the main goal of development is to avoid duplication, but what I see here is lots and lots of duplicated code. Please advise and clarify. Maybe you could suggest a good reading about MVC and coding patterns and best practices in MVC. Because so far, it takes much more time to create a small site using MVC than using my own programming schema.

• Ubuntu on USB does not boot on MacBook

  - by Sean H

  Ubuntu is installed on a 32 gigabyte flash-drive and it successfully booted every time up until I partitioned my hard-drive and installed Windows as a secondary boot (for programming reasons). Now every time I attempt to boot the Ubuntu flash-drive it boots into Windows XP. The same goes for partitions, I partitioned my hard-drive and installed Ubuntu and it only booted Windows XP. I am on a MacBook 6,1 with Mac OS X 10.6.8, 2 partitions, and I am using ReFit as my boot-loader. EDIT: I had Ubuntu working fine from FLASH DRIVE and at one point as a partition. I later uninstalled Ubuntu from my hard-drive and installed Windows. I then had to re-image my computer for certain reasons and I installed windows. Now when I attempt to boot anything other than Windows or OS X it boots into windows. Ubuntu was never on my hard drive while Ubuntu was on it. The flash-drive has been its own thing and has the boot-loader installed to it and loads from ReFit but boots into windows.

• can you have too many dto/bo - mapping method

  - by Fredou

  I have a windows service, 2 web services and a web interface that need to follow the same path (data wise). So I came up with two ways of creating my solution. My concern is the fact that the UI/WS/etc will have their own kind of DTO (let's say the model in ASP.Net MVC) that should be mapped to a DTO so the SL can then map it to a BO then mapping it to the proper EF6 DTO so that I can save it in a database. So I'm thinking of doing it this way to remove one level of mapping. Which one should I take? Or is there a 3rd solution?

• How should I study programming languages?

  - by gcc

  I am a student of computer engineering. I have never done any programming before, and as you can understand, I don't know how to study it or how to make my own programs. My English is weak [edited for clarity - ed], and so if you don't like the choices I list, please feel free to provide others. How should I study? How should I learn programming languages? Study completely from a book. Don't study from a book, just try writing code. A mix of the two; study from a book, then try writing code. Study half the book, then write the code by hand on paper. Listed to the teacher, then try to solve general problems (those not from any specific chapter).

• Is there a modern (eg NoSQL) web analytics solution based on log files?

  - by Martin

  I have been using Awstats for many years to process my log files. But I am missing many possibilities (like cross-domain reports) and I hate being stuck with extra fields I created years ago. Anyway, I am not going to continue to use this script. Is there a modern apache logs analytics solution based on modern storage technologies like NoSQL or at least somehow ready to cope with large datasets efficiently? I am primarily looking for something that generates nice sortable and searchable outputs with the focus on web analytics, before having to write my own frontends. (so graylog2 is not an option) This question is purely about log file based solutions.

• What algorithm(s) can be used to achieve reasonably good next word prediction?

  - by yati sagade

  What is a good way of implementing "next-word prediction"? For example, the user types "I am" and the system suggests "a" and "not" (or possibly others) as the next word. I am aware of a method that uses Markov Chains and some training text(obviously) to more or less achieve this. But I read somewhere that this method is very restrictive and applies to very simple cases. I understand basics of neural networks and genetic algorithms(though have never used them in a serious project) and maybe they could be of some help. I wonder if there are any algorithms that, given appropriate training text(e.g., newspaper articles, and the user's own typing) can come up with reasonably appropriate suggestions for the next word. If not (links to)algorithms, general high-level methods to attack this problem are welcome.
