• Looking for best practice for version numbering of dependent software components

  - by bit-pirate

  We are trying to decide on a good way to do version numbering for software components, which are depending on each other. Let's be more specific: Software component A is a firmware running on an embedded device and component B is its respective driver for a normal PC (Linux/Windows machine). They are communicating with each other using a custom protocol. Since, our product is also targeted at developers, we will offer stable and unstable (experimental) versions of both components (the firmware is closed-source, while the driver is open-source). Our biggest difficulty is how to handle API changes in the communication protocol. While we were implementing a compatibility check in the driver - it checks if the firmware version is compatible to the driver's version - we started to discuss multiple ways of version numbering. We came up with one solution, but we also felt like reinventing the wheel. That is why I'd like to get some feedback from the programmer/software developer community, since we think this is a common problem. So here is our solution: We plan to follow the widely used major.minor.patch version numbering and to use even/odd minor numbers for the stable/unstable versions. If we introduce changes in the API, we will increase the minor number. This convention will lead to the following example situation: Current stable branch is 1.2.1 and unstable is 1.3.7. Now, a new patch for unstable changes the API, what will cause the new unstable version number to become 1.5.0. Once, the unstable branch is considered stable, let's say in 1.5.3, we will release it as 1.4.0. I would be happy about an answer to any of the related questions below: Can you suggest a best practice for handling the issues described above? Do you think our "custom" convention is good? What changes would you apply to the described convention? Thanks a lot for your feedback! PS: Since I'm new here, I can't create new tags (e.g. best-practice). So, I'm wondering if best-pactice is just misspelled or I don't get its meaning.

• Specialized course in Web programming or Generalized course in Computer Science?

  - by Sugan

  I am planning to do my masters in Computer Science in UK. I am interested in Web programming. What should I opt for. A general course in Computer Science or in some specialized course in Web Programming. If web programming, are there a lot of colleges offering these courses. Are there a lot of job offers there in UK. I am not sure whether I can ask this question here. If not point me where I can ask this question.

• How to capitalize maximally on location-independence … my personal #1-incentive for working as a developer

  - by SomeGuy

  To me the ultimate beauty in working as a developer is the fact that given a nice CV, your are going to find a new job, everywhere at any time. So I would like to ask if somebody here as experience in working while travelling for example. Or job-hopping from metropolis to metropolis every, say, six months. For example I have been investigating for how to get to Brazil. But it seems like that working as an employee in Brazil would be no option, b/c it takes a lot of time/money/effort to get the proper visas and permissions. So the only practical solution would be to freelance and the just travel, while getting your job done wherever you are. I bet my ass that there are loads of IT-guys out there and on here who know exactly what I am talking about. I'm looking forward to interesting ideas and stories.

• Is my sequence diagram correct?

  - by Dummy Derp

  NOTE: I am self studying UML so I have nobody to verify my diagrams and hence I am posting here, so please bear with me. This is the problem I got from some PDF available on Google that simply had the following problem statement: Problem Statement: A library contains books and journals. The task is to develop a computer system for borrowing books. In order to borrow a book the borrower must be a member of the library. There is a limit on the number of books that can be borrowed by each member of the library. The library may have several copies of a given book. It is possible to reserve a book. Some books are for short term loans only. Other books may be borrowed for 3 weeks. Users can extend the loans. Draw a use case diagram for a library. I already drew the Use Case diagram and had it checked by a community member. This time I drew sequence diagrams for borrowing a book and extending the date of return. Please let me know if they are correct. I drew them using Visual Paradigm and I dont know how to keep a control of the sequence numbers. If you do, please let me know :) Diagrams

• Is Oberon really "a better Pascal"?

  - by Maksee

  Reading Niklaus Wirth, one can notice that despite some popularity of Pascal, he is not glad that Oberon (as a "polished" successor of Pascal and Modula) didn't get much popularity. I never did anything in Oberon, but reading the page Oberon For Pascal Developers I really did not like many of the changes as a Delphi/pascal developer, for example forcing the reserved words to be always uppercase making the language case-sensitive getting rid of enumeration types What do you think about Oberon, is it really "a better Pascal" from your point of view?

• Architecture strategies for a complex competition scoring system

  - by mikewassmer

  Competition description: There are about 10 teams competing against each other over a 6-week period. Each team's total score (out of a 1000 total available points) is based on the total of its scores in about 25,000 different scoring elements. Most scoring elements are worth a small fraction of a point and there will about 10 X 25,000 = 250,000 total raw input data points. The points for some scoring elements are awarded at frequent regular time intervals during the competition. The points for other scoring elements are awarded at either irregular time intervals or at just one moment in time. There are about 20 different types of scoring elements. Each of the 20 types of scoring elements has a different set of inputs, a different algorithm for calculating the earned score from the raw inputs, and a different number of total available points. The simplest algorithms require one input and one simple calculation. The most complex algorithms consist of hundreds or thousands of raw inputs and a more complicated calculation. Some types of raw inputs are automatically generated. Other types of raw inputs are manually entered. All raw inputs are subject to possible manual retroactive adjustments by competition officials. Primary requirements: The scoring system UI for competitors and other competition followers will show current and historical total team scores, team standings, team scores by scoring element, raw input data (at several levels of aggregation, e.g. daily, weekly, etc.), and other metrics. There will be charts, tables, and other widgets for displaying historical raw data inputs and scores. There will be a quasi-real-time dashboard that will show current scores and raw data inputs. Aggregate scores should be updated/refreshed whenever new raw data inputs arrive or existing raw data inputs are adjusted. There will be a "scorekeeper UI" for manually entering new inputs, manually adjusting existing inputs, and manually adjusting calculated scores. Decisions: Should the scoring calculations be performed on the database layer (T-SQL/SQL Server, in my case) or on the application layer (C#/ASP.NET MVC, in my case)? What are some recommended approaches for calculating updated total team scores whenever new raw inputs arrives? Calculating each of the teams' total scores from scratch every time a new input arrives will probably slow the system to a crawl. I've considered some kind of "diff" approach, but that approach may pose problems for ad-hoc queries and some aggegates. I'm trying draw some sports analogies, but it's tough because most games consist of no more than 20 or 30 scoring elements per game (I'm thinking of a high-scoring baseball game; football and soccer have fewer scoring events per game). Perhaps a financial balance sheet analogy makes more sense because financial "bottom line" calcs may be calculated from 250,000 or more transactions. Should I be making heavy use of caching for this application? Are there any obvious approaches or similar case studies that I may be overlooking?

• Is using MultiMaps code smell? If so what alternative data structures fit my needs?

  - by Pureferret

  I'm trying to model nWoD characters for a roleplaying game in a character builder program. The crux is I want to support saving too and loading from yaml documents. One aspect of the character's is their set of skills. Skills are split between exactly three 'types': Mental, Physical, and Social. Each type has a list of skills under if. My Yaml looks like this: PHYSICAL: Athletics: 0 Brawl: 3 MENTAL: Academics: 2 Computers My initial thought was to use a Multimap of some sort, and have the skill type as an Enum, and key to my map. Each Skill is an element in the collection that backs the multimap. However, I've been struggling to get the yaml to work. On explaining this to a colleague outside of work they said this was probably a sign of code smell, and he's never seen it used 'well'. Are multiMaps really code smell? If so what alternate data structures would suit my goals?

• ROA on top of SOA

  - by Vaibhav Pujari

  I already have a stable Service Oriented Architecture for my application which exposes services as API calls. (the verbs) Now, I need to build a Resource Oriented Architecture to expose a RESTful API to interact with the application objects. (the nouns) What are the best practices to reuse the existing services: - without any persistence inside my new code. - without putting unnecessary logic into the REST layer i.e. it should ideally just leverage the services provided by SOA API. I want this layer to be as thin as possible. - without modifying the existing SOA API - allow easy extension of the REST API i.e. it should be easy to add more resources without changing the (yet to be written) core code. (I want to make resource names and their associated actions configurable so more contributors can easily add resources without a need to understand my module) Any advices/suggestions how to achieve this? Edit: Adding more info My Stack: My existing stacks is in Java. But since I plan to just use the services, I don't think that should affect the design of new REST code. I am planning to implement the new REST code in PHP. How well the services map to resources? Some services are mapped well i.e. there are services for creating, updating application objects. But for other application objects, there are no direct services available. More importantly, there are actions beyond just create, update etc. that apply to application objects. And I would like to provide some way for these actions to be exposed through REST. Since these are verbs, how do I deal with them? Where exactly I need help? I would appreciate any help towards high level design to accomplish the task along-with making the framework extendible. For instance, tomorrow there are some new services added to my SOA layer, I want to make sure it is easy for a fresh developer to write a REST call by simply registering a new resource (in a config file/db) and write code for connecting it with SOA calls. Just like plugin.

• design of 'game engine' for small javascript games?

  - by Matt Ball

  I'm making a group of two or three simple javascript games for fun. After someone finishes one game, they'll be presented with a harder or easier version of another game depending on whether the original game was won or lost. I have a high-level question about the design of things: So far I've created a class for one game type that manages the interaction with the UI and the state of the game itself. But for tracking how many of the subgames have been won, or for understanding whether the next game presented should be more or less difficult, are there arguments to be made for making a 'game engine' class? How does the engine communicate to the games? For instance, when a game is won, how is that information relayed to the engine? Is there a better or more common design? (If you want to see what I have so far, the games are slowly taking shape here: https://github.com/yosemitebandit/candela and can be viewed at http://yosemitebandit.com/candela)

• Learning advanced java skills

  - by moe

  I've been programming in java for a while and I really like the language, I've mostly just done game programming, but I want to get a feel for some of the more commonly used api's and frameworks and just get a generally more well-rounded grasp of the language and the common libraries in the current job market. From what I found things like spring, hibernate, and GWT are pretty in demand right now. I looked at some tutorials online and they weren't hard to follow but I really felt like I had no context for what I was learning - I had no idea how any of it would be use in a real work environment. I know nothing can rival the benefit I'd get from actual work experience but that's not an option for me right now, I need another way to learn these technologies in a way where I'll at least feel comfortable working with them and know what I'm doing beyond just understanding what code does what. I checked out a few books but they were all really old(like pre-2006, am I right to assume those books would be kind of out of date today?) or required experience with libraries that I didn't have and can't get. I hate getting stuck looking for the best resource to learn something instead of spending my time actually learning. All I really want is someone to point me to a resource(website or ebook) that is aimed at already experienced java developers and will not only teach me some interesting useful java technology(anything that is useful, I dont know much outside of graphics libraries and game related things so I was thinking some database or web programming api's) but also give me a good perspective of it and leave me feeling confident that I could actually use what I learned on a practical application. If my post makes you think I'm not yet experienced to be learning these things, which I doubted earlier today but am now starting to question, then what do you think is the next step for me? I just want to get better at java. Thanks everyone

• Assembly load and execute issue

  - by Jean Carlos Suárez Marranzini

  I'm trying to develop Assembly code allowing me to load and execute(by input of the user) 2 other Assembly .EXE programs. I'm having two problems: -I don't seem to be able to assign the pathname to a valid register(Or maybe incorrect syntax) -I need to be able to execute the other program after the first one (could be either) started its execution.

• Changes in licence in forked project what are my rights?

  - by Wes

  Hi I'm intrested in using the apparently now defunct app-mdi libray in a flex application for a paying customer. http://sourceforge.net/projects/appmdi/ It appears that the app-mdi project has been forked from flex-mdi and indeed the code has so much in common it would appear almost identical to the origional code. Now in the original source flex-mdi the following licence appears in the source code /* Copyright (c) 2007 FlexMDI Contributors.

• Nant COM Reference [migrated]

• What are some ramifications of open source software turning into closed source software? [on hold]

  - by Verrier

  If a company takes a permissively licensed open source application and then develops a closed source application from that by reworking extensive parts of the application, adding new features and applying bug fixes... Ignoring any license requirements... How does the transition happen and what can be done to prevent it beyond choosing a difference license? What are the (ethical or social) responsibilities for the company? (For example: Giving back to the open source project would be the ethical thing to do) If the open source version and closed source version are both available, how does the competition affect either product? Are there any examples of companies or products that have done this (either successfully or unsuccessfully) in the past? What was the community attitude toward those projects?

• How do you structure computer science University notes?

  - by Sai Perchard

  I am completing a year of postgraduate study in CS next semester. I am finishing a law degree this year, and I will use this to briefly explain what I mean when I refer to the 'structure' of University notes. My preferred structure for authoring law notes: Word Two columns 0.5cm margins (top, right, bottom, middle, left) Body text (10pt, regular), 3 levels of headings (14/12/10pt, bold), 3 levels of bulleted lists Color A background for cases Color B background for legislation I find that it's crucial to have a good structure from the outset. My key advice to a law student would be to ensure styles allows cases and legislation to be easily identified from supporting text, and not to include too much detail regarding the facts of cases. More than 3 levels of headings is too deep. More than 3 levels of a bulleted list is too deep. In terms of CS, I am interested in similar advice; for example, any strategies that have been successfully employed regarding structure, and general advice regarding note taking. Has latex proved better than Word? Code would presumably need to be stylistically differentiated, and use a monospaced font - perhaps code could be written in TextMate so that it could be copied to retain syntax highlighting? (Are notes even that useful in a CS degree? I am tempted to simply use a textbook. They are crucial in law.) I understand that different people may employ varying techniques and that people will have personal preferences, however I am interested in what these different techniques are. Update Thank you for the responses so far. To clarify, I am not suggesting that the approach should be comparable to that I employ for law. I could have been clearer. The consensus so far seems to be - just learn it. Structure of notes/notes themselves are not generally relevant. This is what I was alluding to when I said I was just tempted to use a textbook. Re the comment that said textbooks are generally useless - I strongly disagree. Sure, perhaps the recommended textbook is useless. But if I'm going to learn a programming language, I will (1) identify what I believe to be the best textbook, and (2) read it. I was unsure if the combination of theory with code meant that lecture notes may be a more efficient way to study for an exam. I imagine that would depend on the subject. A subject specifically on a programming language, reading a textbook and coding would be my preferred approach. But I was unsure if, given a subject containing substantive theory that may not be covered in a single textbook, people may have preferences regarding note taking and structure.

• Will JVisualVM degrade application performance?

  - by rocky

  I have doubts in JVisual VM profiler tool related to performance. I have requirement to implement a JVM Monitoring tool for my enterpise java application. I have gone through some profiling tools in market but all them are having some kind of agent file which we need include in server startup. I have a fear that these client agent will degrade my application performance will more. So I have decided to JVisual VM because this profiler tool comes with JDK itself but before implementing JVisualVM, does anybody faces any issues with JVisualVM profiler tool? As well as, is this safe if I implement in application?

• What language should I use for making a cross platform library?

  - by Andrei

  I want to build a SyncML parsing library (no UI) which should be able to build up messages based on information provided by the host application, fed in by the library's methods. Also, the library should to be able to do callbacks to methods in the host application. I want to be able to compile this and have it available on as many platforms as possible: Windows, Windows Phone 7 OS, OSX, iOS, Linux, Android, BlackBerry. Basically as many platforms as possible. The priority is to have this available on mobile devices. Questions: What setup should I use? (programming languages, compilers, IDE etc.) How would I compile this library for these different platforms and how would I connect to it? Any other info? e.g. articles that cover the subject of cross-platform development? I haven't done this sort of a cross-platform project before, so any available information to put me in the right direction would be welcomed. Myself, I have a background in C#/.NET and Objective-C.

• Is it okay to be generalist?

  - by Londoner

  I work at a ~50 employee company (UK), where all the technical people do a bit of everything. Specialising in anything for very long (6 months) is discouraged. For example, last week, I built a new Debian webserver, refactored some Perl, sat on a sales phone call, did a tape backup, reviewed code, built and deployed an RPM, gave opinions about x, y, z... With such a work scheme, I have gained a general knowledge how many things work, and pretty specific knowledge. I maybe program for 5 hours a week, despite officially being a developer. Does anyone else work like this, (or is this company unique)? Is it a problem to have skills developed in this way? (i.e. know a bit about everything in a certain domain, rather than know everything about say, one programming language?) Is it okay to be a generalist?

• Idea to develop a caching server between IIS and SQL Server

  - by John

  I work on a few high traffic websites that all share the same database and that are all heavily database driven. Our SQL server is max-ed out and, although we have already implemented many changes that have helped but the server is still working too hard. We employ some caching in our website but the type of queries we use negate using SQL dependency caching. We tried SQL replication to try and kind of load balance but that didn't prove very successful because the replication process is quite demanding on the servers too and it needed to be done frequently as it is important that data is up to date. We do use a Varnish web caching server (Linux based) to take a bit of the load off both the web and database server but as a lot of the sites are customised based on the user we can only do so much. Anyway, the reason for this question... Varnish gave me an idea for a possible application that might help in this situation. Just like Varnish sits between a web browser and the web server and caches response from the web server, I was wondering about the possibility of creating something that sits between the web server and the database server. Imagine that all SQL queries go through this SQL caching server. If it's a first time query then it will get recorded, and the result requested from the SQL server and stored locally on the cache server. If it's a repeat request within a set time then the result gets retrieved from the local copy without the query being sent to the SQL server. The caching server could also take advantage of SQL dependency caching notifications. This seems like a good idea in theory. There's still the same amount of data moving back and forward from the web server, but the SQL server is relieved of the work of processing the repeat queries. I wonder about how difficult it would be to build a service that sort of emulates requests and responses from SQL server, whether SQL server's own caching is doing enough of this already that this wouldn't be a benefit, or even if someone has done this before and I haven't found it? I would welcome any feedback or any references to any relevant projects.

• Recommendation for a platform to teach game development to kids [closed]

  - by Moshe Kravchik

  My 11 years old son decided he want to create a Web game. He does not know much about programming and I never did any game development so I'm not the best teacher of the topic. On one hand I really want him to get into building things and doing his own game sounds perfect. So I'd like to find a way to keep him interested and progressing by himself. This means that I'm looking for a platform that is: 1. Simple for understanding and use, intuitive interface 2. Powerful 3. Good tools, preferrably free 4. Significant community for questions and tips 5. Localization - my son's English is quite poor (native Hebrew). We looked at Alice, but it was too limited in its abilities and isn't really a Web game building platform. HTML/CSS and Javascript - too low level for a kid to keep the interest. What would you recommend?

• ASP.NET MVC Controllers & Actions In Regards To URLs And SEO

  - by user1066133

  The general idea is that if I were to create an MVC site, simple pages such as the contact and about pages will be placed under the Home Controller. So my URL would look like http://www.mysite.com/home/contact, and http://www.mysite.com/home/about. The above works just fine, but I really don't like the idea of having the "home" portion in the URL. So what negatives would there be if I decided to make a controller name of Contact and About and just added a single Index action so that way the URL would be simplified to http://www.mysite.com/contact and http://www.mysite.com/about. This method looks cleaner. Do any of you do the same or something similar? I've been trying to work on SEO for an escort service site I've developed and when you search for the females the link looks like http://www.mysite.com/escorts/female-escorts, and like-wise for males. I'm wondering if I should remove the Escorts Controller and just create a Female_Escorts Controller with an Index Action only so it comes out like the above as http://www.mysite.com/female-escorts.

• How can I save my university's Computer Science & Engineering department? [closed]

  - by Blake

  I'm currently pursuing a B.S. in Computer Engineering at the University of Florida, and we're having a bit of a problem right now... The state recently passed a budget plan that cuts funding for higher education in Florida. The dean of UF's College of Engineering decided that the best way for us to absorb the blow is by executing the following plan: All of the Computer Engineering Degree programs, BS, MS and PhD, would be moved from the Computer & Information Science and Engineering Dept. to the Electrical and Computer Engineering Dept. along with most of the advising staff. Roughly half of the faculty would be offered the opportunity to move to Electrical/Computer Eng., Biomedical Eng., or Industrial/Systems Eng. Staff positions in CISE which are currently supporting research and graduate programs would be eliminated. The activities currently covered by TAs would be reassigned to faculty and the TA budget for CISE would be eliminated. Any faculty member who wishes to stay in CISE may do so, but with a revised assignment focused on teaching and advising. In short: our department (at least as we know it) is being decimated. Computer & Information Sciences & Engineering (one of 9 departments in the College of Engineering) is taking more than 50% of the cuts. If you're interested in reading the full proposal, you can access it here. A vast, VAST majority of the students and faculty in the department are vehemently opposed to this plan, however the dean is already taking measures to implement it. This is the only proposal on the table right now, and she has not entertained our requests for alternatives. She sees it as an obvious (albeit drastic) solution to our budget problem, citing that many other universities have combined Computer and Electrical Engineering departments. I'll bet those universities didn't have to eliminate an established department to get there, though. The budget goes into effect July 1, 2012 (this is non-negotiable), and the dean's proposal is currently set to be finalized some time next week. We don't have much time! My question to everyone here is this: Are we overreacting to this plan, or are we justified? And could you explain why or why not? It's obvious that CISE students will resist any cuts to our department, but I'm curious to see what other people in the field have to say. Any feedback is greatly appreciated. I will select the answer that saves our department. Just kidding, I'll pick the one that best explains why this is a good or bad decision for the dean to make. Please note that anything you say can and will be used to further our cause (and we might track you down if you provide a compelling argument against us).

• What would a start-to-finish development procedure would look like?

  - by Tom Busby

  I have a problem that my developer friends share. We recently left university and find ourselves either end up working for a firm which already has good procedures (TDD, automated testing, proper agile development, etc) or working for a firm which doesn't. I want to learn some of these vital skills and get a grip on what a complete start-to-finish development procedure would look like. What differences would be between a smaller project, and a long term project with many team members.
