• Distance Education in Computer Science - HCI

  - by Rionmonster

  I have been a software engineer / graphic designer for a few years and have recently been considering furthering my education in the field. (It was actually a very generous Christmas present) I would primarily be interested in something like Human Computer Interaction or a similar "creative technology" that involves heavy UI/UX Design, prototyping or Information Architecture. Anyways - I still plan on working full-time and was looking into part-time distance programs and was wondering if anyone had some experience with pursuing a similar degree (either from a distance or in-person) and could share their experiences. Thanks!

• A scheme for expiring downloaded content?

  - by Chad Johnson

  I am going to offer a web API service that allows users to download and "rent" content for a monthly subscription fee. The API will either be open to everyone or possibly just select parties (not sure yet). Each developer must agree to a license, and they receive a developer key for their person. Each software application will have its own key as well. So then end-users will download the software which will interact with my service's API. Each user will have a key for each application as well (probably using OAuth). Content will be cached on first download and accessible offline via just the third-party application that cached the content. If a user cancels their subscription, I plan on doing the following: Deactivate the user's OAuth key for all applications. Do not allow the user's account to download new content via the API (and subsequently any software that uses the API). Now, the big question is: how do I make content expire if they cancel their subscription? If they cancel, they should not have access to content anymore. Here are ideas I've thought of (some of these are half-solutions, not yet fully fleshed out): Require that applications encrypt downloaded content using the user's OAuth key, making it available to only the application. This will prevent most users from going to the cache directory and just copying and keeping files. Update the user's key once a month, forcing content to re-cache on a monthly basic. Users could then access content for a month after they cancel their subscription. Require applications to "phone home" [to the service] periodically and check whether the user's subscription has terminated. If so, require in the API developer license that applications expire cache. If it is found that applications do not comply, their keys (and possibly keys for all developers) are permanently deactivated as a consequence. One major worry is that some applications may blatantly ignore constraints of the license. Is it generally acceptable to rely on applications abiding by the licensing constraints? Bad idea? Any other ideas? Maybe a way to make content auto-expire after x days? Something else? I'm open to out-of-the-box ideas.

• Benefits of using the same language for client and server?

  - by Makita

  I'm looking at architecture solutions for a mobile project that will have a web-service/app in addition to native apps. I've been looking at various libraries, frameworks, and stacks like jqm, backbone, parse, and meteor. Meteor, sort of an "open stack package framework", is tightly bound with node.js. There is a lot of talk about the benefits of using the same language both client and server side, and I'm not getting it. I could understand if you want to mirror the entire state of a web application on both client and server but struggling to find other wins... Workflow efficiency? I'm trying to understand why client/server language parity is considered to be a holy grail, any explicit examples or links would be greatly appreciated, thanks!

• What are good ways to guarantee business continuity with a SaaS product?

  - by tommyvdz

  For my Bachelor Thesis I am researching how SaaS providers can arrange some sort of business continuity guarantee. You probably know the Source Code Escrow arrangements for 'shrink-wrapped' software. They give customers access to the source code and all applicable documentation whenever the software supplier gets into (financial) trouble. This clearly does not work for SaaS, because customers have no use for just the source code, and customers probably can not afford not being able to login to their CRM system for a couple weeks because the SaaS provider went bankrupt. I am currently researching different methods to solve this problem. Do you know good and practical solutions to solve this continuity problem? Or companies that already offer a good solution? Thanks!

• How to use rel=canonical with Sitecore aliases?

  - by Mike G

  I have inherited a Sitecore architecture that is a mess from an SEO duplicate content POV. There are multiple aliases that have been created (and indexed by the search engines) for many of the 2nd tier pages of the site. Due to server issues, I am not able to 301 redirect these duped pages, so I would like to use the rel=canonical tag in an attempt to try and get Google/Bing to recognize the correct pages I would like to appear in the index. I have blocked the most extraneous duped pages with a robots.txt file, however, since Google/Bing have already spidered many of the duped pages, I need to keep them accessible to the spiders, BUT removed from the index. The catch is, since the duped pages are aliases (and don't really physically exist in Sitecore that I can find), I am not sure how to go about using rel=canonical - or if I even can in this situation..?

• How to prevent the copying of text from a textarea?

  - by think123

  I have an online typing software, which I'm currently working on. In the typing software, all is running good but I have come across the problem of dishonest users who might possibly type the text into the textarea, copy it, then reload the page (therefore resetting the timer) and pasting it in straightaway. So I was thinking along the lines of using something like evt.preventDefault(); when javascript detects the pressing of the ctrl / cmd button. But then again I realized that the user could go to the menu bar to press copy. So is there a cross-browser method to do both methods of disabling? Thanks, Lucas EDIT: Please forgive me if I wasn't clear. Please comment on where I wasn't, and I will strive to improve the quality of my questions.

• gem install cannot find a header file

  - by Milktrader

  Following along the github README for talib_ruby: sudo port install ta-lib Complete. Next is where the trouble begins. sudo env ARCHFLAGS="-arch PLATFORM" gem install talib_ruby -- --with-talib-include=ABSOLUTE_PATH_TO_TALIB_HEADERS --with-talib-lib=ABSOLUTE_PATH_TO_TALIB_LIBS This install fails I believe because apparently it cannot find the ta_abstract.h file talib.c:2:25: error: ta_abstract.h: No such file or directory . . . many more errors I have included in my .bash_profile file the following: export ABSOLUTE_PATH_TO_TALIB_HEADERS=/opt/local/var/macports/software/ta-lib/0.4.0_0/opt/local/include/ta-lib export ABSOLUTE_PATH_TO_TALIB_LIBS=/opt/local/var/macports/software/ta-lib/0.4.0_0/opt/local/lib And indeed the ta_abstract.h file is located where I'm saying in the ABSOLUTE_PATH variable assignment. What gives?

• How to design console application with good seperation of UI from Logic

  - by JavaSa

  Is it considered an overkill for console application to be design like MVC , MVP or N tier architecture? If not which is more common and if you can link me to simple example of it. I want to implement a tic tac toe game in console application. I have a solution which hold two projects: TicTacToeBusinessLogic (Class library project) and TicTacToeConsoleApplication (Console application project) to represent the view logic. In the TicTacToeConsoleApplication I've Program.cs class which holds the main entry point (public static void Main). Now I face a problem. I want the game to handle its own game flow so I can: Create new GameManager class (from BL) but this causing the view to directly know the BL part. So I'm a little confused how to write it in an acceptable way. Should I use delegates? Please show me a simple example.

• What is the current legal status of magnet links?

  - by Moonwalker

  Prelude: I develop a cloud service which could be described as dropbox meets torrents and as side effect it enables distribution of arbitrary content via magnet links. Certain amount of magnet links will be displayed on the main website (I will be able to remove them one-by-one or ban users but no more). I will not be able to avoid magnets without complete rework of overall project architecture and either way it will hurt overall performance badly, probably making service meaningless. So my question is, what should I do, to avoid legal problems if my site in a nutshell is just a collection of magnet links? Privacy achieved via end-user encryption, so there is almost no access restrictions on the website. And anyway will help me any? Will hosting in particular country help me?

• Follow the deadlines vs Do it right

  I have been given a huge task of migrating few functionalities from jQuery to AngularJS. I have been pretty good at Angular by now. But I want to dive deep and create futuristic, sound architecture. BAs are seating on my neck, wanting to get my tasks as quickly as possible. I prefer doing something once and right vs keeping on patching existing functionalities. And with this attitude, I always keep working more than necessary. Am I missing something? Am I having right approach or am just not convincing enough BAs my point. What's the best approach, in your opinion Thank You :)
