• Interfacing the payment systems

  - by etranger

  Hello all. I'm a complete newbie to using online payment systems for web projects, and can't really think of where to start. Let's assume that web system in question needs to generate some income online, and the business idea/functionality is in place, while organizing cash flow is the only unsolved problem. Points of interest are how the custom developed software interfaces to payment systems, and how the resulting income is available to the owner. I do understand that there are probably hundreds of systems out there, but to be more specific on which of them suit, I'd have to know how they work, and that's where I don't feel like understanding much. Thanks in advance.

• Pros and cons of developing modern services in Java

  - by r3mus

  I'm interested in the philosophical and architectural justification (or lack thereof) in using Java to develop in today's modern world (exclude mobile/embedded platforms of course). Why would one choose to develop (or not develop) a back-end in Java? Why would one choose to develop (or not develop) a front-end UI in Java? Why do large enterprises lean towards developing in Java rather than adopt more modern (and standardized) technologies? *disclaimer: I'm not a fan of Java in the enterprise, I'm simply curious what drives enterprises to continue the trend.

• Online iPad 1&2 emulators give different results compared to the real thing

  - by Systembolaget

  I'm designing a centered website (jQuery Isotope). Thre sandbox is here. I have used some online iPad 1&2 emulators to test how the site is viewed on these devices. Then, I managed to get hold of the real thing. Result: on real iPads, the site is centered and the layout adjusts automatically as expected. In online iPad emulators, the site is not quite centered and additional Isotope elements are squeezed in. Of course, I trust the real thing more than online emulators, but why is this happening? To me, it feels like website testing with online emulators is not so reliable after all? If this question is wrong here, please move it or tell me where it should go. SO is about programming, this question isn't. Thanks!

• Ubuntu App Contest - Open Source Libraries

  - by Chao

  I just found out about and started looking into the Ubuntu App Contest, and I wanted to double check the contest's stance on using open source libraries built by others that are freely available on the web. I read through the rules and some of the other Q&As, and it sounds like using these libraries would not be allowed (since it could mean the app isn't built from scratch, and the library would not be in the Ubuntu archive - although I could bundle the library with the app), and I just wanted to verify this assumption. Thanks! Chao

• what do I need to do to get started with a website? [closed]

  - by omar

  I am a student and I have made websites for some companies before but now I would like to make a generic website for myself but dont know how to get started as I never had to deal with hosting or bandwidth before. I am looking to make a website that will provide users with information about me. In the future I might add things such as ordering or buying products but for now the idea is to provide information only. I was told not to go for any webhoster outside of Canada as I might risk the confidential integrity of my users or myself. I have no idea where to get started or what I need. I now also have to deal with possible security issues or security holes I may leave in my website creation... So my question here is: What is a good and reliable webhosting company that can be trusted to some degree?

• Why do the GNOME symbolic icons appear darker in a running application?

  - by David Planella

  I'm creating an application that uses symbolic icons from the default theme. However, there are a few icons that I need that cannot be represented by those from the default theme, so I'm creating my own ones. What I did was to simply go to /usr/share/icons/gnome/scalable/actions/, copied a few locally into my app's source tree that could serve as a basis, and started editing them. So far so good. But I've noticed the following: all symbolic icons are of a light grey color when looking at the original .svg file, but when they are put onto a widget, they become darker. Here's an example, using the /usr/share/icons/gnome/scalable/actions/view-refresh-symbolic.svg icon from the default theme: Here's what it looks like when opening the original with Inkscape: And here's what it looks like on a toolbar on a running application: Notice the icon being much darker at runtime. That happens both with the Ambiance and Radiance themes. I wouldn't mind much, but I noticed it affects my custom icon, whereby parts of it become darker (the inner fill), whereas parts of it remain the same color as the original (the stroke). So what causes the default symbolic icons to darken and how should implement that for my custom icons?

• Learning Programming from scratch

  - by David542

  I am entirely new to programming, other than basic HTML/CSS knowledge. I want to learn programming as quickly and efficiently as possible, and I'm willing to put in the time (at least 70 hours a week). The reason I want to learn is because I have a startup that I've written a business plan for and have prototyped in Photoshop (both front-end and back-end pages). My goals is to have a prototype of the site up within 6 months. I have a good aptitude for math (A's in all math courses up through DiffEq and Linear Algebra). I assume learning programming from scratch can be a daunting task -- not because it is particularly difficult, but because there are so many areas and so much information. I want to make sure that I learn as efficiently as possible and have individuals (in addition to Google) to solicit advice from and that will help me when I get stuck or have questions. I know with other's help, my learning experience will be both more productive and enjoyable. What is the best way to find people that will help me in this? What are some good 'live' resources in addition to asking questions on Stack Overflow? Thank you very much for your time and help.

• Real Time Monitoring System using .net [closed]

  - by sameer

  I need to develop the application which display the dashboard where data from various SQL DB is fetched from different servers and displayed. Now this need to happen real time we can have refresh time say 5 min. Here is my thought, suggest if anything is wrong. 1) To Develop the Windows Service to accumulate the data from various SQL Server Instance. 2) Then Persist those details into SQL DB from which Dashboard will displayed on the web page. 3) Fetch of data from Windows service will be trigger every x minutes. 4) SQL Server Instance details will be stored in SQL DB which Windows Service will be referring. Thus this approach make sense. Thanks..

• How should I describe the process of learning someone else's code? (In an invoicing situation.)

  - by MattyG

  I have a contract to upgrade some in-house software for a large company. The company has requested multiple feature additions and a few bug fixes. This is my first freelance style job. First, I needed to become familiar with how the application worked - I learnt it as if I was a user. Next, I had to learn how the software worked. I started with broad concepts, and then narrowed down into necessary detail before working on each bug fix and feature. At least at the start of the project, it took me a lot longer to learn the existing code than it did to write the additional features. How can I describe the process of learning the existing code on the invoice? (This part of the company usually does things in-house, so doesn't have much experience dealing with software contractors like me, and I fear they may not understand the overhead of learning someone else's code). I don't want to just tack the learning time onto the actual feature upgrade, because in some cases this would make a 'simple task' look like it took me way too long. I want break the invoice into relevant steps, and communicate that I'm charging for the large overhead of learning someone else's code before being able to add my own to it. Is there a standard way of describing this sort of activity when billing for a job?

• is there a formal algebra method to analyze programs?

  - by Gabriel

  Is there a formal/academic connection between an imperative program and algebra, and if so where would I learn about it? The example I'm thinking of is: if(C1) { A1(); A2(); } if(C2) { A1(); A2(); } Represented as a sum of terms: (C1)(A1) + (C1)(A2) + (C2)(A1) + (C2)(A2) = (C1+C2)(A1+A2) The idea being that manipulation could lead to programatic refactoring - "factoring" being the common concept in this example.

• Software vs Network Engineer (Salary, Difficulty, Learning, Happiness)

  - by B Z

  What are your thoughts on being a Software Engineer vs a Network Engineer? I've been on the software field for almost 10 years now and although I still have a great deal of fun (and challenges), I am starting to think it could be better on the "other" side. Not to degrade network engineers (i know there are many great ones out there), it seems (in general) their job is easier, the learning curve from average to good is not as steep, job is less stressful and pay is better on average. I think as software developer I could make the switch to networking and still enjoy working with computers and feel productive. I spend an enormous amount of time learning about software, practices, new technologies, new patters, etc...I think I could spend a much smaller amount of time learning about networking and be just as "good". What are your thoughts? EDIT: This is not about making easy money. Networking and Software are closely related, I love computers and programming, but if I can work with both, make more money and have less stress in my life and can spend more time with my family, then I am willing to consider a change and hence I am looking for advice that Do or Don't support this view.

• What would it take to get developers to pay for something that is already freely available as open source?

  - by plaureano

  For example, I know that open-source versions of IL readers/writers exist such as Cecil, and Microsoft's (closed source) CCI. What would it take to get developers to pay for something that is already freely available? I have always wanted to start my own ISV by writing my own tools and selling them in the open market, but it's hard to gauge the demand, given that free alternatives already exist. Does anyone else have any successful experiences selling a commercial version of an open-source product?

• Why are 3D game scenarios so big? and.. are them shareable? [closed]

  - by Néstor Sánchez A.

  First, I apologize if this is not the forum for these type of questions. I was wondering... 1- Why 3D games (such as GTA IV) uses so much gigabytes of space? And my half-answar was... because of their huge 3D scenarios. But wait! are not these scenarios made with vector graphics and textures? then.. why are so big??? 2- If they are so big... would really these companies make a whole new scenario for every new game they develop? that would be very inefficient. Doesn't exist "shareable" scenarios that can be used in different games and expanded to no rebuild a whole one (like "New York" or "Liberty City")???. I mean.. the scenarios is almost the same in terms of vertices, just with improved textures.

• What are the advantages of myBatis over Hibernate?

  - by Kshitiz Sharma

  This question originates from a comment I received on one of my questions - I'd rather drop hibernate in favor of mybatis instead of jdbc I've done some research on my own and understand the basic concept. But some insights can only be gained through actual experience. What are the advantages of myBatis that would make it worth learning a new framework? In what case would you avoid using it?

• Authenticating users for a website

  - by MCB

  I'm working on a website and I want to validate that an individual is an employee at one of a large number of companies (probably using their company's email address, which I don't know before hand). The idea being some users are the general public and others are from these companies. And I need some way to authenticate that the users claiming to be employees are being honest while still having a friendly enough UI. I did an informal survey of people I know and the domains and emails will match in a majority of cases but they might not always match exactly so you might have a company with a website foo.com and an email [email protected] (although foobar.com did redirect back to foo.com). And while I can easily check that I'm not sure what other variations might be out there (maybe fooLA.com and email [email protected], etc.)

• Is it a must to focus on one specific IT subject to be succesful?

  - by Ahmet Yildirim

  Lately I'm deeply disturbed by the thought that I'm still not devoted to one specific IT subject after so many years of doing it as a hobby. I've been in so many different IT related hobbies since I was 12. I have spent 8 years and now I'm 20 and just finished freshman year at Computer Eng. Just to summarize the variety: 3D Game Dev. and Modelling (Acknex, Irrlicht , OpenGL, GLES, 3DSMAX) Mobile App.Dev (Symbian, Maemo, Android) Electronis (Arduino) Web.Dev. (PHP, MYSQL, Javascript, Jquery, RaphaelJS, Canvas, Flash etc.) Computer Vision (OpenCV) I need to start making money. But I'm having problem to pick the correct IT business to do so. Is it a problem to have interest in so many different IT subjects?(in business world) I'm having a lot of fun by doing all those stuff from time to time. Other than making money I also noticed that having so many different interests is lowering my productivity. But I'm still having difficulty to pick one. I'm feeling close to all those subjects (time to time).

• How to market yourself as a software developer?

  - by karlphillip

  I have noticed that this is a frequent issue among younglings from technical areas such as ours. In the beginning of our careers we simply don't know how to sell ourselves to our employers, and random guy #57 (who is a programmer, but not as good as you - technically) ends up getting a raise/promotion just because he knows how to communicate and market himself better than you. Many have probably seen this happen in the past, and most certainly many more will in the future. What kind of skill/ability (either technical, or of other nature) do you think is relevant to point out when doing a job interview or asking for a raise, besides listing all the programming languages and libraries you know?

• Transferring local site to shared hosting

  - by Pete

  I'm looking to setup a simple online text processing tool similar to the Clang demo. The processing program itself is a C++ program which I can modify to provide the desired output I need. Since I use Linux+Perl daily and have used Apache in the past, I'd like to get this working locally first. My two questions are: Is it possible to do this with only Apache and Perl? I've looked into frameworks for doing this and quickly ran into The Paradox Of Choice. Will I be able to easily transfer a working local site to a shared hosting service? I want to administer as little as possible. My understanding is since this needs to run a C++ program that CGI is a requirement and thus I need to administer the httpd server. Hopefully this doesn't mean a VPS. Thanks

• How do I get my programs to communicate with each other

  - by Benjamin Lindqvist

  I'm basically just getting started with programming. The problem I have with progressing is that I have a hard time learning stuff just for the sake of knowing them - I do better when there's a problem to be solved or a task to be completed so I can learn 'on the job'. So I'm interested in starting some interesting project. I know the basics of Python, Java, Matlab and some C++ aswell and I know enough about microcontrollers to make LED blink etc. The type of stuff I'm looking for is for example scraping some weather forecast site (with Python) and outputting the chance of rain to a LCD display, or a program that makes chrome open and log in to facebook if I say "HAL, time for facebook", or more generally, a program that reads serial/USB input, looks for certain sequences and sends instructions to some other program if it finds one. Do you open some kind of shared stream in which one program reads and one writes? What do I need to read up on to do accomplish this myself? I have no experience with linux or the linux terminal, but looking over peoples shoulders makes me suspect that's what people use. Is that correct?

• How do you stop yourself from programming?

  - by dan

  Lately I've started earning enough off my software to not have to do consulting to support myself. So I work full time designing and writing my own software products. The problem is that there are no boundaries between my work and my life any more. When I mostly did consulting, I was weary enough of work at the end of the workday to go home and do other things. But now, I sit down to program in the morning, and before I know it it's 11pm and I'm still writing software and not bored or tired at all. I have to force myself to go to sleep. I feel happy and fulfilled, but objectively, I know I need more balance and variety in my life. Any tips or suggestions on how to pull yourself away from the console?

• What is the most efficient way to study multiple languages, frameworks, and APIs as a developer?

  - by Akromyk

  I know there are those out there who have read a slurry of books on a specific technology and only code in that one particular language, but this question is aimed at those who need bounce around between using multiple technologies and yet still manage to be productive. What is the most efficient way to study multiple languages, frameworks, and APIs as a developer without becoming a cheap swiss army knife? And how much time should one dedicate to a particular subject before moving to another?

• Getting the URL to the Content Type Hub Programmatically in SharePoint 2010

  Many organizations use the content-type hub to manage content-types in their SharePoint 2010 environment.  As a developer in these types of organizations, you may one day find yourself in need of getting the URL of the content type hub programmatically.  Here is a quick snippet that demonstrates how to do it fairly painlessly: public static Uri GetContentTypeHubUri(SPSite site) {     TaxonomySession session = new TaxonomySession(site);     return Session.DefaultSiteCollectionTermStore         .ContentTypePublishingHub; }
