• Techniques and methods to improve and speedup development

  - by Jlouro

  I just got a new project. It’s a WinForm app. And it’s interesting because I will have the possibility to learn how fish farms work and are managed. I will have to develop touch interfaces, and use datasnap to communicate and sync data between farm and office. The development will be done in DELPHI win32, still not sure about the database, but maybe SQLlite. So now comes the difficult part of the project, building it. I am just finishing one. It took me a lot of time to do it and I am a bit “burned out”. I will have time to relax, not much, but a few days. What I am looking is some tips and tricks and possibly tools to be able to speed up the development. It must be up and running in 2 months. So what tricks do you use to speed up things?

• How do I completly remove software? [closed]

  - by Dustin

  Possible Duplicate: Why are the hidden settings-folders not deleted when purging an application? Ok I have 8GB on my desktop dual booting win 7. I installed a few games, assualtcube, tremolous, and spring. But I had removed them using 'remove --purge' and only to find they are still lingering and purge does not well truly purge them. I need them completely gone and not secretly hogging space when I purged them. How can i completely remove software, like it is gone and not going to take any more of my precious space? Shrinking 7 and growing Ubuntu is not an answer I am accepting, i want to know how to completely remove software. Thank you for your time and your answers.

• Ubuntu Software Center (10.04LTS) Missing Packages

  - by Chris

  I recently downgraded from 11.10 to 10.04LTS for compatibility and support of specific development tools. The Ubuntu Software center is missing many packages that I had access to in 11.10, most notably LibreOffice. (Also development tools.) Is there a way to update software sources to find the missing packages? (Or are they incompatible with 10.04?) Synaptic does not have libre either. I feel like I am working with a gimped version of USC.

• Using cracked software and tools [closed]

  - by Lena Aslo

  I am seeing people complaining about expensive tools such as Dreamweaver or Photoshop. I am just wondering about that, because everyone knows that they can get this software running for free (if it is done illegally). Why don't they just use a cracked version? Is it so likely to get caught? I feel that nowadays a lot of people are using cracked software but whenever the topic is mentioned, they ALL say PSSST!!! or start criticizing it, even though they are doing it themselves...

• Software Architecture Analysis Method (SAAM)

  Software Architecture Analysis Method (SAAM) is a methodology used to determine how specific application quality attributes were achieved and how possible changes in the future will affect quality attributes based on hypothetical cases studies. Common quality attributes that can be utilized by this methodology include modifiability, robustness, portability, and extensibility. Quality Attribute: Application Modifiability The Modifiability quality attribute refers to how easy it changing the system in the future will be. This to me is a very open-ended attribute because a business could decide to transform a Point of Sale (POS) system in to a Lead Tracking system overnight. (Yes, this did actually happen to me) In order for SAAM to be properly applied for checking this attribute specific hypothetical case studies need to be created and review for the modifiability attribute due to the fact that various scenarios would return various results based on the amount of changes. In the case of the POS change out a payment gateway or adding an additional payment would have scored very high in comparison to changing the system over to a lead management system. I personally would evaluate this quality attribute based on the S.O.I.L.D Principles of software design. I have found from my experience the use of S.O.I.L.D in software design allows for the adoption of changes within a system. Quality Attribute: Application Robustness The Robustness quality attribute refers to how an application handles the unexpected. The unexpected can be defined but is not limited to anything not anticipated in the originating design of the system. For example: Bad Data, Limited to no network connectivity, invalid permissions, or any unexpected application exceptions. I would personally evaluate this quality attribute based on how the system handled the exceptions. Robustness Considerations Did the system stop or did it handle the unexpected error? Did the system log the unexpected error for future debugging? What message did the user receive about the error? Quality Attribute: Application Portability The Portability quality attribute refers to the ease of porting an application to run in a new operating system or device. For example, It is much easier to alter an ASP.net website to be accessible by a PC, Mac, IPhone, Android Phone, Mini PC, or Table in comparison to desktop application written in VB.net because a lot more work would be involved to get the desktop app to the point where it would be viable to port the application over to the various environments and devices. I would personally evaluate this quality attribute based on each new environment for which the hypothetical case study identifies. I would pay particular attention to the following items. Portability Considerations Hardware Dependencies Operating System Dependencies Data Source Dependencies Network Dependencies and Availabilities  Quality Attribute: Application Extensibility The Extensibility quality attribute refers to the ease of adding new features to an existing application without impacting existing functionality. I would personally evaluate this quality attribute based on each new environment for the following Extensibility  Considerations Hard coded Variables versus Configurable variables Application Documentation (External Documents and Codebase Documentation.) The use of Solid Design Principles

• personality problem while learning web development [closed]

  - by Lazeera

  I work a lecturer and when I go home I find a lot of free time. The problem is that I spend most of my time in learning about web development. I don't go outside and don't meet people, I'm only in front of the screen drinking 4 cups of coffee (per day) and trying to learn many technologies related to web development. In the last, I don't learn things very well because I'm in a hurry. I know this place is for asking about programming but I want to learn from your experience regarding learning. How do you learn? How many hours do you spend in leaning a day? How can I organize my time so I can learn well and easily?

• Software patents [closed]

  - by user71622

  not exactly sure where I should post this but I have a question about filing for software patents. If I have an idea for a UI feature, how do I go about patenting that feature. I don't have any code written and I'm afraid my coding skills aren't up to snuff in order to code the thing I imagined but aside from that, can anyone give me any general guidance and info? I've gone through the CIPO site (Canada's patent office) but haven't come away with enough information on what I'm trying to patent but what I have understood is that I have to very thorough in describing what I'm trying to patent and showing that it could work. If anyone has gone through the process of patenting software, can you tell me about your experience? I would like to hear about US and Canadian experiences Thank you!

• Optical Character Recognition software recommendations?

  - by Tim

  I have seen some ebooks/papers that were apparently scanned from their paper versions but the text in the ebooks/papers can amazingly be copied out. I suppose the directly-scanned versions must have been processed by some Optical Character Recognition software. So I would like to know what are the recommended Optical Character Recognition softwares? Especially those that are either for Ubuntu or free? If those for Windows are far more superior, please let me know as well. I am particularly interested in those OCRs that can accept a scanned pdf file as input and still produce as output another pdf file that looks the same as the input one but with its text copyable. Thanks and regards! Please limit one software per answer

• Software Center crashes and terminal errors

  - by user97521

  *note*I'm a new user to Ask Ubuntu and I've only recently switched to Ubuntu 12.04. When I try to open the software center (Ubuntu 12.04 32-bit) it will flash open, load for maybe 1-2 seconds, and then close. When i try using: sudo apt-get purge software center sudo apt-get install sudo apt-get update sudo apt-get upgrade I get this within the terminal: Reading package lists... Error! E: Problem parsing dependency Depends E: Error occurred while processing printer-driver-hpcups (NewVersion2) E: Problem with MergeList /var/lib/dpkg/status E: The package lists or status file could not be parsed or opened. *The problem fixed itself after I shut down my laptop for the night and turned it back on to check my e-mail this afternoon. If anyone could tell me how to fix this problem in the future please do, I would like to learn about these kind of things because i don't plan on putting windows on my laptop again :P *

• Documenting software architectures that serve multiple markets

  - by wsb3383

  Hello, I'm the lead developer/architect wanna-be on a J2EE based system/platform at work that serves both real estate and automotive markets. The systems consists of a set of database back ends, web services and two web clients. The platform ends up serving 3 different products: an internal vehicle inventory system for use by company analysts, an external dealer management system (commercialized product), and a real estate inventory system (commercialized). In other words, it follows a software product lines approach....My question is, I'm having trouble communicating to other technical and some business people how this platform architecture is one system that serves multiple markets (by leveraging some existing assets combined with minor modifications)....Is there a formal modeling language that can simplify communicating this intent? I should note that I haven't read much about software product lines, so I'm not sure if there is actually a standard modeling approach to SPL that i'm not aware of....I'm also interested in knowing if there are special configuration management practices for such systems. thanks,

• Abstraction, Politics, and Software Architecture

  Abstraction can be defined as a general concept and/or idea that lack any concrete details. Throughout history this type of thinking has led to an array of new ideas and innovations as well as increased confusion and conspiracy. If one was to look back at our history they will see that abstraction has been used in various forms throughout our past. When I was growing up I do not know how many times I heard politicians say “Leave no child left behind” or “No child left behind” as a major part of their campaign rhetoric in regards to a stance on education. As you can see their slogan is a perfect example of abstraction because it only offers a very general concept about improving our education system but they do not mention how they would like to do it. If they did then they would be adding concrete details to their abstraction thus turning it in to an actual working plan as to how we as a society can help children succeed in school and in life, but then they would not be using abstraction. By now I sure you are thinking what does abstraction have to do with software architecture. You are valid in thinking this way, but abstraction is a wonderful tool used in information technology especially in the world of software architecture. Abstraction is one method of extracting the concepts of an idea so that it can be understood and discussed by others of varying technical abilities and backgrounds. One ways in which I tend to extract my architectural design thoughts is through the use of basic diagrams to convey an idea for a system or a new feature for an existing application. This allows me to generically model an architectural design through the use of views and Unified Markup Language (UML). UML is a standard method for creating a 4+1 Architectural View Models. The 4+1 Architectural View Model consists of 4 views typically created with UML as well as a general description of the concept that is being expressed by a model. The 4+1 Architectural View Model: Logical View: Models a system’s end-user functionality. Development View: Models a system as a collection of components and connectors to illustrate how it is intended to be developed.  Process View: Models the interaction between system components and connectors as to indicate the activities of a system. Physical View: Models the placement of the collection of components and connectors of a system within a physical environment. Recently I had to use the concept of abstraction to express an idea for implementing a new security framework on an existing website. My concept would add session based management in order to properly secure and allow page access based on valid user credentials and last user activity.  I created a basic Process View by using UML diagrams to communicate the basic process flow of my changes in the application so that all of the projects stakeholders would be able to understand my idea. Additionally I created a Logical View on a whiteboard while conveying the process workflow with a few stakeholders to show how end-user will be affected by the new framework and gaining additional input about the design. After my Logical and Process Views were accepted I then started on creating a more detailed Development View in order to map how the system will be built based on the concept of components and connections based on the previously defined interactions. I really did not need to create a Physical view for this idea because we were updating an existing system that was already deployed based on an existing Physical View. What do you think about the use of abstraction in the development of software architecture? Please let me know.

• Should Development / Testing / QA / Staging environments be similar?

  - by Walter White

  Hi all, After much time and effort, we're finally using maven to manage our application lifecycle for development. We still unfortunately use ANT to build an EAR before deploying to Test / QA / Staging. My question is, while we made that leap forward, developers are still free to do as they please for testing their code. One issue that we have is half our team is using Tomcat to test on and the other half is using Jetty. I prefer Jetty slightly over Tomcat, but regardless we using WAS for all the other environments. My question is, should we develop on the same application server we're deploying to? We've had numerous bugs come up from these differences in environments. Tomcat, Jetty, and WAS are different under the hood. My opinion is that we all should develop on what we're deploying to production with so we don't have the problem of well, it worked fine on my machine. While I prefer Jetty, I just assume we all work on the same environment even if it means deploying to WAS which is slow and cumbersome. What are your team dynamics like? Our lead developers stepped down from the team and development has been a free for all since then. Walter

• Distributed Development Tools -- (Version control and Project Management)

  - by Macy Abbey

  Hello, I've recently become responsible for choosing which source control and project management software to use for a company that employs me. Currently it uses Jira (project management) and Subversion (version control). I know there are many other options out there -- the ones I know about are all in this article http://mashable.com/2010/07/14/distributed-developer-teams/ . I'm leaning towards recommending they just stay with what they have as it seems workable and any change would have to be worth the cost of switching to say github/basecamp or some other solution. Some details on the team: It's a distributed development shop. Meetings of the whole team in one room are rare. It's currently a very small development team (three developers). The project management software is used by developers and a product manager or two. What are you experiences with version control and project management web applications? Are there any you would recommend and you think are worth the switching cost of time to learn new services / implementing the change? Edit: After educating myself further on the options it appears DVCS offer powerful benefits that may be worth investing in now as opposed to later in the company's lifetime when the switching cost is higher: I'm a Subversion geek, why I should consider or not consider Mercurial or Git or any other DVCS?

• Who practices, or is likely to practice, the IEEE Software Engineering? [closed]

  - by user72757

  There is an interesting issue in Software Engineering which I'd like to explore. The issue is firstly what is and what is not software engineering. Secondly, if software engineering is what the IEEE defines it to be, what are good examples of companies which practice the SE? Detailed question: Software engineering (SE) is the application of a systematic, disciplined, quantifiable approach to the design, development, operation, and maintenance of software, and the study of these approaches; that is, the application of engineering to software. [updated definition, originating in 610.12-1990 - IEEE Standard Glossary of Software Engineering Terminology] If we consider as SE only those approaches that 100% match the above definition, we naturally get to SWEBOK (Software Engineering Body of Knowledge) which is created by the IEEE and the ACM. I'm seeking the answer to this: How can I find a company outside the defence industry which practices the SE as defined by IEEE? Clues: SE originates in 1968 NATO conference. The Software Engineering Institute (SEI) is based in the US at Carnegie Mellon University. Funding of the SEI is largely done by the US DoD. Defence industry uses the SE and sometimes has a partnership with the IEEE (as in case of Boeing). Possible decomposition of my big question into smaller chunks: a) Where is anyone who acknowledges the IEEE Software Engineering standards at work and perhaps even uses some of them? http://cs.hbg.psu.edu/cmpsc487/IEEEStds_List.htm b) Where can I find a person or a company building around SWEBOK? http://www.computer.org/portal/web/swebok/html/contents c) What is an example of a company professionally using CSDP (apart from those at IEEE website)? Does anyone have any possible contribution to this question?

• Software management for 2 programmers

  - by kajo

  Hi all, me and my very good friend do a small bussiness. We have company and we develop web apps using Scala. We have started 3 months ago and we have a lot of work now. We cannot afford to employ another programmer because we can't pay him now. Until now we try to manage entire developing process very simply. We use excel sheets for simple bug tracking and we work on client requests on the fly. We have no plan for next week or something similar. But now I find it very inefficient and useless. I am trying to find some rules or some methodology for small team or for only two guys. For example Scrum is, imo, unadapted for us. There are a lot of roles (ScrumMaster, Product Owner, Team...) and it seems overkill. Can you something advise me? Have you any experiences with software management in small teams? Is any methodology of current agile development fitten for pair of programmers? Is there any software management for simple bug tracking, maybe wiki or time management for two coders? thanks a lot for sharing.

• Development environment to manage multiple Oracle databases

  - by jkohlhepp

  I am in an enterprise environment where we have applications that need to run against multiple Oracle databases. Developers may need to manage multiple vintages of these databases to support different test data or diagnose bugs against different versions of the code. Right now, we have a limited set of test environments set up on "real" Oracle servers within the data center. We juggle these among development and QA groups and there is a lot of conflicts and inefficiencies that arise because of it. I am taking a look at Oracle Express Edition which would allow me to spin up a local Oracle database. This is similar to the workflow I most often see with SQL Server. Devs work on their location machine until they are ready to integration and then they push their DB changes to integration / QA environments. However, from what I read it seems that Oracle XE only supports one database instance at a time. So if I have an application that utilizes two different databases, I can't have both of them running on my local machine. Is that correct? Does Oracle Standard or Personal editions get around this limitation? If I had one of those installed locally, how difficult would it be to get multiple databases working on the same development machine? How do dev shops handle developing against Oracle where they need to be using several different Oracle instances for their applications?

  Background I work in a non-IT based company, as a professional software developer, building a large scale internal database system. I am fortunate to have a fairly senior position within the company, and have been working here for around 4 years. Often I get asked by management "how do you learn new things?". To be honest, I don't know how to answer this. Over the last 6 months, I've really gotten my teeth into some new techniques and technologies to make my level of coding far better and hopefully improve the quality of the software. Even if it's just refreshing my skills on things I've learnt already. Like last week I dived into some complex XLinq and TPL code (.net). Nothing revolutionary, but I feel like I am a bit better than before. Question The question is, how do I prove this to my employer? It'd be nice to be able to put this on paper. Possibilities I could: Keep a journal of what I've learnt - keeping the technical bits in (nobody would understand or care, but it's better than them being omitted) ???? (I've run out of ideas already) Any ideas? Thanks, Tom

• How can I compare between web development technologies?

  - by Steve

  I would like experts to explain for me how can I compare between web development tools or technologies in order to be able to choose the right one. I'm tired from searching always in the regular way: X Technology vs Y Technology. I'm tired from peoples' biased opinions and usually I don't find a fair comparison. I have decided to put my question here about how can I compare them so you may identify to me the main standards for comparisons so I can compare them by myself and becoming able to choose the technology that is appropriate for the project I will develop. Note: in web development technologies I mean server side languages (e.g. PHP). One important requirement for me that can be defined as major one is cost efficiency and I mean that I don't care about the cost in the near future or the current cost, but what is more important for me is the cost in the future. If, for example, the site becomes one of the most 100 visited sites.   So, how can I compare the cost of different technologies for a future status of a site (such as being very famous site) so I can scale my option easily without missing a good technology like what happened with some sites when they chose not the most effective tool.

• How to better integrate a unix development environment into Windows

  - by SKenz

  I'm mostly a Windows user but I do most of my development (essentially web development) using unix tools and software. I've been going back and forth between using a dedicated lubuntu virtual machine on Virtualbox and using some tools directly in windows (msgit, python, django), but none of these approaches is entirely satisfactory. I'd like to hear of ways other devs use to better integrate a unix workflow into windows. For instance tighter integration between a linux and vm and windows. The vagrant demo showed how a VM could work off of a windows project folder and I found that nice. I'd like to hear of other tools and tips that would help mimic the workflow one can find on OS X (of course I understand that it cannot be as tightly integrated on Windows as it doesn't have the same unix underpinnings). PS: I have tried cygwin as well EDIT for clarifications about What I find lacking (thanks to axblount for pointing that out) : unix tools like msys et al do not work as well as their native unic counterparts. Many scripts, installers require further configuration or do not work at all. For instance getting virtualenvwrapper to work is not very straightforward. virtualbox: ideally I would like to use windows software (photoshop, sublime text 2) seamlessly with linux. I mostly use a FTP client atm to move over files edited on the windows side which is a tedious process.
