• How important is to sacriface your free time for accomplishing goals? [closed]

  - by Darf Zon

  I was reading a book about XP programming and about agile teams. While I was reading, I saw this scenario. I've never worked with a development team (just in school). So I would like what do you opine on this situation: Your boss has asked you to deliver software in a time that can only be possible to meet the project team asking if you want to work overtime without pay. All team members have young children. Discuss whether it should accept this request from your boss or should persuade the team to give their time to the organization rather than their families. What could be significant factors in the decision? As a programmer, you are offered an upgrade as project manager, but his feeling is that you can have a more effective contribution in a technical role in one administrative. Write when you should accept that promotion. Somethimes, I sacrifice my free time for accomplishing hits at work, so it's very important to me to know your opinion base of your experience.

• Using an AGPL 3.0-licensed library for extra functionality in an iOS app

  - by Arnold Sakhnov

  I am building an iOS application, and I am planning to incorporate an AGPL 3.0-licensed library to it to provide some extra (non-essential) functionality. I’ve got a couple of questions regarding this: Do I understand it right that this still obliges me to publish the source of my app open? If yes, does it have to be open to the general public, or only to those who have downloaded the app? Does this allow me to distribute the app for a fee?

• Subsumption architecture vs. perceptual control theory

  - by Yasir G.

  I'm a new person to AI field and I have to research and compare 2 different architectures for a thesis I'm writing. Before you scream (homework thread), I've been reading on these 2 topics only to find that I'm confusing myself more.. let me first start with stating briefly what I know so far. Subsumption is based on the fact that targets of a system are different in sophistication, thus that requires them to be added as layers, each layer can suppress (modify) the command of the layers below it, and there are inhibitors to stop signals from execution lets say. PCT stresses on the fact that there are nodes to handle environmental changes (negative feedback), so the inputs coming from an environment go through a comparator node and then an action is generated by that node, HPCT or (Hierarchical PCT) is based on nesting these cycles inside each other so a small cycle to avoid crashing would be nested in a more sophisticated cycle that targets a certain location for example. My questions, am I getting this the right way? am I missing any critical understanding about these 2 models? also any idea where I can find simplified explanations for each theory (so far been struggling trying to understand the papers from Google scholar :< ) /Y

• Find vertices of a convex hull

  - by Jeff Bullard

  I am attempting to do this within CGAL. From a 3D point cloud, find the convex hull, then loop over the finite facets of the convex hull and print each facet's vertices. It seems like there should be a straightforward way to do this; I would have expected that 3D polyhedra would own a vector of facet objects, each of which in turn would own a vector of its edges, each of which in turn would own a vector of its vertices, and that their would be some access through this hierarchy using iterators. But so far I have been unable to find a simple way to navigate through this hierarchy (if it exists).

• Should CSS be listed on your resume under Languages?

  - by Sandeepan Nath

  I have some doubts like Whether CSS should be put under Languages or not? Although Wikipedia says Cascading Style Sheets (CSS) is a style sheet language ... But do they write CSS under the languages section of the resume, along with PHP, etc? Similarly what about HTML? I have some doubt and I don't want to sound like someone who is not aware of the trends. Just to give an example, currently I have the following languages,frameworks, technologies, etc. listed under the "Technical Expertise" section of my resume - Technical Expertise * Languages - Proficient - PHP 5, Javascript, HTML ?*,CSS ?*,Sass ?*. Beginner - Linux Bash. * Databases - MySQL 5. * Technologies - AJAX. * Frameworks/Libraries - Symfony, jQuery. * CMSes - Wordpress. Although my domain is Web-development/design, I welcome domain-agnostic answers which can provide some generic ideas/reasoning. I have seen, a lot of people messing up these sections (even more serious than my doubts :) ), putting things under wrong sub-headings and thus putting a big question mark on their understanding of those things. I don't know much about XML, Comet Technology etc. Considering those are included too, What things should be put under Languages? E.g. Should CSS be put under Languages? Please give some reasoning to support your views. Where should the others (XML, Comet, cURL etc. ) be put? I welcome some examples of how you put it. Or do you have an additional Keywords section where you write all the unsortables ? Considering a set of standards like W3C standards, etc. do you have a standards sub-heading? I guess I have put the contents of other sections Okay. But do let me know about your ideas and reasoning. After all, I understand there may not be a single answer to this, but let's see what is the trend. Thanks Updates Further, do you mention design patters you have used? Web Services etc.? Where do you mention SOAP, XML etc...

• How do I learn Python from zero to web development? [closed]

  - by Terence Ponce

  I am looking into learning Python for web development. Assuming I already have some basic web development experience with Java (JSP/Servlets), I'm already familiar with web design (HTML, CSS, JS), basic programming concepts and that I am completely new to Python, how do I go about learning Python in a structured manner that will eventually lead me to web development with Python and Django? I'm not in a hurry to make web applications in Python so I really want to learn it thoroughly so as not to leave any gaps in my knowledge of the technologies involving web development in Python. Are there any books, resource or techniques to help me in my endeavor? In what order should I do/read them? UPDATE: When I say learning in a structured manner, I mean starting out from the basics then learning the advanced stuff without leaving some of the important details/features that Python has to offer. I want to know how to apply the things that I already know in programming to Python.

• Complex Release Vehicle Management

  - by Sharon

  I'm looking into improving our build and release system. We are a .Net/Windows shop, and I don't see any really good tools for Windows for generating the files that are to be dropped in patch or hotfix. We are currently using TFSBuild 2010 with Windows Workflows for our continuous integration builds as well as our daily full build which includes an Installshield package for deployment. What is a good way of generating the list of files to be included in a "patch" style release, where one does not redistribute all the files, but only those necessary to accomplish the necessary changes? Are there any open source tools that work well for this, or do teams usually roll their own? I have considered using Beyond Compare but I would prefer something open source. The file "patch" creation must be 100% automatable. Which release vehicles really ought to be patch style? And which releases should replace all system files related to our application? Assume we have a very large amount of resources necessary to maintain. Is there any established material that is trusted within the industry for strategies about this? I realize it is different for "enterprise" rather than with typical websites. I am looking more for "enterprise" strategies due to our product distribution style. tl;dr Looking for info on how to ship more reliable packages?

• Buy vs. Build - FTP Service

  - by Joel Martinez

  We have a need to FTP files that are generated by our system, so we're trying to decide whether we should spend the time to build something that meets our criteria (relatively easy, .NET has FTP functionality built in, among other more advanced libs from 3rd parties). Or if we should buy something off the shelf. Our requirements are roughly: Must be able to trigger a file send programmatically Needs to retry N number of times (configurable) Queryable status of FTP requests Callback on completion or fail of an FTP request I don't need to be sold on the relative simplicity of building something like that for myself. However I do want to do the due diligence of seeing what products are available ... because if something does exist that matches the requirements above, I wouldn't mind paying for it :-) Any thoughts or links would be greatly appreciated. Thanks!

• Is there an alternative to javascript for the web that can do multi-threading and synchronous execution?

  - by rambodash

  I would like to program web applications as I do with desktop programming languages, where the code is synchronously executed and browser doesn't freeze when doing loops. Yes I know there are workarounds using callbacks and setTimeout, but they are all workarounds after all and they don't give the same flexibility when programming in the orthodox way I've been looking at Dart as a possibilty, but I can't seem to find where it says it can do either of these. The same with haxe, emscript, and the hundreds of other converters that try to circumvent javascript. In the end it gets converted to Javascript so you ultimately have to be conscious about asynchronous/multi threading.

• Does double-shifting as a PM affect your developer-productivity?

  - by Roopesh Shenoy

  Has it ever happened to you that you are a good developer but suddenly you need to lead a team or are responsible for some PM activities as well? Did you find that it affected your productivity? How did you handle it? I love my job, but I sometimes feel I was much happier as a programmer and the additional burden of being a Project Manager is currently affecting my productivity as a developer. What do you guys suggest as remedies to this? I do not have an alternative currently to quit from my job - basically because Im working for a startup that I co-founded.

• General questions regarding open-source licensing

  - by ndg

  I'm looking to release an open-source iOS software project but I'm very new to the licensing side of the things. While I'm aware that the majority of answers here will not lawyers, I'd appreciate it if anyone could steer me in the right direction. With the exception of the following requirements I'm happy for developers to largely do whatever they want with the projects source code. I'm not interested in any copyleft licensing schemes, and while I'd like to encourage attribution in derivative works it is not required. As such, my requirements are as follows: Original source can be distributed and re-distributed (verbatim) both commercially and non-commercially as long as the original copyright information, website link and license is maintained. I wish to retain rights to any of the multi-media distributed as part of the project (sound effects, graphics, logo marks, etc). Such assets will be included to allow other developers to easily execute the project, but cannot be re-distributed in any manner. I wish to retain rights to the applications name and branding. Futher to selecting an applicable license, I have the following questions: The project makes use of a number of third-party libraries (all licensed under variants of the MIT license). I've included individual licenses within the source (and application) and believe I've met all requirements expressed in these licenses, but is there anything else that needs to be done before distributing them as part of my open-source project? Also included in my project is a single proprietary, close-sourced library that's used to power a small part of the application. I'm obviously unable to include this in the source release, but what's the best way of handling this? Should I simply weak-link the project and exclude it entirely from the Git project?

• Which version of Java should I use for learning?

  - by Dan

  I am a QA engineer interested in mobile development and automation.I have basic programming experience (intermediate level Python, C++ programmer) and as most companies choose Java for writing frameworks I need to pickup Java. I use Ubutnu 12.04 LTS and I will be using Head First Java as learning material. When I searched for JDK options I found Oracle Java 6 and 7 and Open JDK. I read somewhere in Ubuntu forums that Java 6 is not recommended on Ubuntu systems and I am a little bit confused about which version should I use, that would be compatible with the book and the OS.

• Transition from maintenance programming to design

  - by andrew wang

  What to do people do develop a design for a s/w for a given set of requirements? I like many people joined a Semiconductor MNC and got stuck in maintenance for quite a couple of years. My work was usually changing a lines of code for windows drivers supplied by my company or a couple of small script (style like) C programs for validating h/w. As a result I developed the bad habit of 'programming by coincidence'. I have not developed the ability for designing tools/programs from scratch. I was the only s/w member of the local team and thus some grunt work from the well established other site of the company came to be done by me. Now I have moved to a different company and thus finding developing from scratch very difficult. How do I unlearn my bad habit and develop this ability of designing s/w and then coding it ?

• android third party libraries

  - by Terrance

  Its hard to believe that there aren't a ton of awesome third party (possibly open source) libraries out on the web for android using java but, I cant say I have found a great many so far but, droid seems like the only notable one I've come across. Any other majorly useful android libraries out there? Sorry in advanced if there is a dupe out there somewhere (seems like there should be) but if there is by all means post it and let me know.

• Are there open source alternatives to Bitbucket, Github, Kiln, and similar DVCS browsing and management tools?

  - by Ryan Taylor

  I am aware of several tools/services that provide DVCS browsing and management such as Bitbucket, Github, Kiln, SCM-Manager and Rhodecode. However, the use case I am considering is one such that: Any source code must reside on an employers internal servers. The solution must be open source. It should provide a Bitbucket or Github like experience, including a project wiki, repository browsing and management, and social coding aspects such as code review. The solution should have mercurial support (if not support for other DVCSs). Of these, only SCM-Manager and RhodeCode come close as they can be installed on your own servers and are open source. However they do not have the Bitbucket or Github experience. There is no issue tracker or wiki and the UI, while functional, is not up to par with Github or Bitbucket. I can get close with Trac or Redmine with their repository browsers but unfortunately they do not have any repository management capabilities. Are there other open source tools out there that would provide a similar experience to Bitbucket, Github or Kiln?

• Determining Cost of API Calls

  - by Sam

  [This is a cross-post originally posted by me in SO. I think the question is more appropriate here.] I was going through the adwords API and came across their rate sheet - http://code.google.com/apis/adwords/docs/ratesheet.html . They charge $0.25 per 1000 API units and under the 'Operation Costs' sections list the cost (in API units) of different API calls. I am curious - based on what factors do they (and others API developers) calculate the cost of an API call? Is there any simple formula or a standard way to determine this? Note: When I say 'cost' of an API call, I don't mean the money but the API units. For example, how do you determine one API call costs 100 'units' and another 1000?

• VB.Net Sub reports problem in SS Reporting Services

  - by user65697

  I am trying to transfer over some MS Access reports to VB.Net via sql reporting services. Currently using VB.Net in Visual Studio 2008. I have 5 sub reports that need to run. Depending on the user selection any number of them can show at one time in the report viewer. So I assume I need to use a main report which holds the sub reports. How do I populate the data for each sub report when the main container report loads? Do I need to set the datasource of each subreport dynamically? Do I also need to dynamically load the subreports into the report viewer? Any code appreciated. Thanks

• How to increase ad revenue

  - by Brian515

  I have an Android game in which I've included ads from Millennial Media and Admob. Between these two networks, my fill rate is consistently above 95%. Right now, I'm getting over 45,000 requests for ads per day, and I'm starting to see exponential growth. But, my eCpm for both Millennial and Admob is ridiculously low. Millennial's is $.12 and Admob's is $.01. I've been reading some other posts and it seems like people are getting between $1 and $4 per 1,000 views. How can increase mine? Thank you!

• English to French translation of computing terminology

  - by Rich

  I work in France as a Java programmer, mainly in French, but am a native English speaker. My level of French is pretty good (French wife!), but one thing I have problems with is working out whether to use English terminology or a French equivalent. Examples: lock (as in a synchronisation lock) - do I use the verb "locker" or do I use verrouiller? shard (databases) - "un shard" or "un tesson" (which means a shard of glass) ...and so-on... So, what do people recommend? Can anyone point out some good websites for translating this kind of terminology? The usual online translation tools are a bit too everyday English/French, not the slightly more specialised version that I find myself needing.

• Developing for Windows CE platform?

  - by grmbl

  I'm looking in creating some applications for workers to use on the workfloor. They'll be using Psion NEO devices running Windows CE 5.0. My skillset allows for C#, PHP, ASP.Net (+ webservices). Application requirements: should connect to our ERP system running on IBM iSeries (AS400). should be run in fullscreen (effectively hiding the OS). usability touch functionality. I have tried the following: Full winform application ran through RDP session: [+] easy deployment using .rdp file. [+] application can be run on desktop environment too. [+] rdp host can easily access DB2 using IBM drivers. [+] GUI works ok on small screen. [-] environment = terminal server. (which is already under heavy use) Full winform application running on device OS: [+] environment = local. [+] responsive. [-] must use a webservice to access DB2. [-] deployment... [-] fixed platform (no desktop) Console application running on device OS: [+] environment = local. [+] very responsive. [-] must use a webservice to access DB2. [-] no fullscreen or other window options? [-] deployment... [-] fixed platform (no desktop) I'm considering creating a web application but it seems the OS comes with IE 5? I don't want to alter the OS in any way! (install other browsers etc.) I would like to have an application that's responsive, easy to deploy, fullscreen and optionally multiplatform. I have seen handheld devices using terminal (emulation?) with a console like interface. This seems to be native to the device but I'm afraid this requires modest knowledge of C++? It seems that using RDP is the way to go but, I came here for advice and look for people that have been in the same situation willing to share their experience. There does not seem to be many "best practices" on the web that could help me decide the best way of working. Greetings

• How to depict Import a file action in the Sequence diagram

  - by user970696

  Everyone says sequence diagrams are so easy but I just cannot figure this out. Basically user clicks on an 'Import from temp folder' button, the program opens a window with a list populated with filenames, user clicks on a filename, clicks on OK and the document is imported. I know the order of the actions but how to depict e.g. populating a list, or selecting an item from a list? So I assume the objects would be like: [USER] [ImportDialogWindow] [ListOfFiles:STRING] [?where to go with selected file]

• Is it a bug or a task when something doesn't work, yet, in development process

  - by Patkos Csaba

  We usually have this dilemma in our team. Sometimes, in order to implement a task or a story we find out that the system must be in a specific state. For example, a specific system configuration has to be made beforehand. The task / story can be completed and it is working as specified on it with the proper configuration in place. Note that the configuration is not directly related with the task. Next, we have to create a new ... ??? ... something for the process of generating that configuration file. This is where the problems appear. Some say that it is a bug others say it is a task or an extra feature. So, where is the limit between bugs and tasks in the development phase? Should we even consider something a bug if all the tasks are working as stated in their definitions? Can a thing be considered a bug because one compares it to the current (unstable) state of the system? Short example: A feature requires configuring a communication service for a specific operation. In the process of the implementation the team discovers that the service requires the hostnames of the pears to be resolvable to an IP address. The team adds the hostnames to the DNS server (or hosts files) and continues implementing the required feature. After the initial feature is working, a question is risen. Should the sysadmin configure the DNS or hosts file or should our application do it automatically? An automatic solution is possible. So a decision is made to implement it. ... here start the discussions ... is this a bug or an extra feature / task? PS: I know that I mixed feature / task / story in the question. It is intentional. I am interested in separating bugs from the rest. Doesn't matter what the rest means in a particular case.

• unit/integration testing web service proxy client

  - by cori

  I'm rewriting a PHP client/proxy library that provides an interface to a SOAP-based .Net webservice, and in the process I want to add some unit and integration tests so future modifications are less risky. The work the library I'm working on performs is to marshall the calls to the web service and do a little reorganizing of the responses to present a slightly more -object-oriented interface to the underlying service. Since this library is little else than a thin layer on top of web service calls, my basic assumption is that I'll really be writing integration tests more than unit tests - for example, I don't see any reason to mock away the web service - the work that's performed by the code I'm working on is very light; it's almost passing the response from the service right back to its consumer. Most of the calls are basic CRUD operations: CreateRole(), CreateUser(), DeleteUser(), FindUser(), &ct. I'll be starting from a known database state - the system I'm using for these tests is isolated for testing purposes, so the results will be more or less predictable. My question is this: is it natural to use web service calls to confirm the results of operations within the tests and to reset the state of the application within the scope of each test? Here's an example: One test might be createUserReturnsValidUserId() and might go like this: public function createUserReturnsValidUserId() { // we're assuming a global connection to the service $newUserId = $client->CreateUser("user1"); assertNotNull($newUserId); assertNotNull($client->FindUser($newUserId); $client->deleteUser($newUserId); } So I'm creating a user, making sure I get an ID back and that it represents a user in the system, and then cleaning up after myself (so that later tests don't rely on the success or failure of this test w/r/t the number of users in the system, for example). However this still seems pretty fragile - lots of dependencies and opportunities for tests to fail and effect the results of later tests, which I definitely want to avoid. Am I missing some options of ways to decouple these tests from the system under test, or is this really the best I can do? I think this is a fairly general unit/integration testing question, but if it matters I'm using PHPUnit for the testing framework.

• I have 5 days of vouchers for MS training… help me choose? [closed]

  - by Shyatic

  I'm a Microsoft centric guy (systems engineering side) and I already know the syntax of VB, have done VBScript pretty extensively and Excel VBA stuff as well. I want to make the leap into proper programming, probably with C# because it teaches me syntax I can use for Java if I want to go that route at some point. Since I have vouchers for 5 days of programming, and I can understand logic and understand how the .NET framework works... I would love to hear ideas on which MS Courses I should take. My primary focus is to work on web applications with web services that interact and do neat stuff... like for example, to create a 'chat' room or something interactive on the web. Or should I do something with HTML5/JS? I am really not sure... like I said, I want to work to make web services/sites. Not making the next Facebook mind you, but I'd like to work towards something in that spectrum on a much smaller scale. Please give me any advice, I'd like to book these classes asap Obviously getting involved with SQL and things that I will require would be important here.. you guys know better than me! Thanks!
