  • Credit Card Payment Processing which APIs do you use?

    - by user3330840
    It's for a Point of Sale Terminal where the customer will bring the physical credit card and it will be swiped through the terminal. The business has a merchant account on some banks. So, how do I start accepting credit cards in my app? The credit cards that needs to be accepted include: visa, master-card, amex, discover. Which APIs do I need to use? The programming language doesn't matter it can be in any programming languages Java/C#/C++/Python or anything. Will there be a single API or multiple APIs that need to be integrated? (I know some about PCI compliance and security encryption)

  • Ops Center and Oracle Solaris 11

    - by user12609425
    There have been a few questions about Ops Center and S11 recently. People have been trying to discover and update S11 from Enterprise Controllers installed on S10 or Linux, and running into problems, and wondering what the solution is. Well, the solution is that, if you want to be able to discover, monitor, and update S11 OSes, you need to install your Enterprise Controller and at least one Proxy Controller on S11 systems. The Oracle Solaris and Linux install guides both note this in the chapters that cover preparing your environment. Technically, if you have an S11 Proxy Controller you can at least discover, manage, and monitor S11 systems. However, features like the automated installer and the image packaging system (for OS updates) can only be used through Ops Center if your Enterprise Controller is installed on S11 as well.

  • Dual-boot question involving separate HD and windows 8

    - by user286976
    I use an external HD with Ubuntu+GRUB on it. This allows me to effectively "hijack" most systems. Basically it's a permanent LiveUSB - my own system wherever I go. I use it for recovery mainly when Windows systems muck up, and for portability (as I can have my system on the go, without effecting the pc I'm borrowing, much like a LiveCD). I'm about to update to Windows 8 now [on a new, different computer]. Is there any special measure I should take to do this? I've seen a similar post here, but the OP had both harddrives plugged in simultaneously - that's not exactly my setup. Thank you :) EDIT: added for clarification that this is for a totally new computer.

  • Many ui panels needs interaction with same object

    - by user877329
    I am developing a tool for simulating systems like the Gray-Scott model (That is systems where spatial distribution depends on time). The actual model is loaded from a DLL or shared object and the simulation is performed by a Simulation object. There are at least two situations when the simulation needs to be destroyed: The user loads a new model The user changes the size of the domain To make sure nothing goes wrong, the current Model, Simulation, and rendering Thread are all managed by an ApplicationState object. But the two cases above are initiated from two different UI objects. Is it then ok to distribute a reference to the ApplicationState object to all panels that need to access at least one method on the ApplicationState object? Another solution would be to use aggregation so that the panel from which the user chooses model knows the simulation parameter panel. Also, the ApplicationState class seems somewhat clumsy, so I would like to have something else

  • Why does installing 11.10 or 12.04 on old laptops fail?

    - by Adam
    I recently reimaged my Lenovo t400 with Ubuntu. However, after wiping two other systems (Compaq Presario 2100 and Dell Latitude D600) both hUbuntu 11.10 and Ubuntu 12.04 fail to load on boot. I am concerned that there is some type of issue using Ubuntu on these older systems as every part of the process has been repeated/attempted several times in the same manner as practiced in the successful load of the newer Lenovo t400. I now have two laptops without an operating system as the discs/thumb drives that were formatted to load on these devices do not seem to work. I would appreciate any assistance that you may be able to provide. Regards, -Adam

  • What exercises counter the back pain of sitting at a computer for 15 hours a day? [on hold]

    - by Sam
    I work up to 15 hours a day (not everyday :)) programming. When I do this I get a very sore lower back. I don't want to spend $1000 on a special chair like Joel Spolsky says. I'm sure I'm not alone here. Has anybody encountered this and found an exercise/other method to combat it? Maybe somebody with more physical education than me about opposing muscle groups or something. PS (not working fifteen hours a day isn't an answer, it's how I work best) and it's not off topic as programming is about more than code - it's a verb.

  • Organizations that encourage kids to program

    - by mwgriffith
    Since my son started going to school, I've been noticing a very serious lack of organizations to encourage kids to program or at least letting them know how to get involved in programming. Are there any groups that you know of to help kids out this area?? And I'm not referring to tools to help kids learn, I'm referring to groups that will help in getting kids interested in programming. Here are a few that I know of: Dreamspark Lego First Robotics Imagine Cup Are there anymore out there? And are there any that work at the elementary - high school levels?? Also are there any other parents that have noticed the same thing, or is this local to my area??

  • Programmer, software engineer, computer scientist What's the difference? [closed]

    - by ForgottenKahz
    Possible Duplicate: What are the key differences between software engineers and programmers? What's the difference between computer science and programming? Whats the difference between a Software Architect, a Software Engineer, and a Software Developer (Programmer)? What is the actual difference between Computer Programmers and Software Engineers? Is this description accurate? What's the difference between computer science and programming? I want to know the difference between a programmer, a software engineer and a computer scientist. I'm new to the scene and I don't want to step on anybody's toes. I once gloated to a programmer that I was learning MS Access. Boy, was that a mistake. But when my father in law contracted some of his work out to software engineers their code was junk. In the world of software development, who goes by what title? Does it matter?

  • Non-object-oriented game tutorials

    - by Arcadian
    I've been tasked with writing an essay extolling the virtues of object oriented programming and creating an accompanying game to demonstrate them. My initial idea is to find a tutorial for a simple game written in a programming language which does not follow the OOP paradigm (or written in an OOP language but not in an OOP way) and recreate it in an OOP way using either C# or Java (haven't yet decided). This would then allow me to make concrete comparisons between the two. The game doesn't have to be anything complex; Tetris, Pong, etc. that sort of thing. The problem I've had so far is finding a suitable tutorial, any suggestions?

  • How to bridge the gap between university and job requirements

    - by user1762636
    I study physics and computer science and both studies include minor programming tasks whereas larger tasks are only (potentially) a part of larger projects like for your thesis. When I look at job postings for scientific jobs e.g. in the area of HPC they usually ask for "extensive programming skills in C/C++ and HPC" or the like. This is what I would like to achieve, but frankly I don't know how. I don't mean to mourn, but you can imagine that studying physics/CS means having a busy schedule so I couldn't even work part time as a research assistant to get practice without negative influence on my grades. The second problem is that I lack ideas on what to code in my spare time. I would like to do something useful but even for open source projects you apparently need a whole lot of time and depending on the type of software a lot of experience to be useful. I would be grateful for any advice you can give me.

  • From Java to Javascript? [duplicate]

    - by theGreenCabbage
    This question already has an answer here: Are there any OO-principles that are practically applicable for Javascript? 2 answers I am primarily a Java programmer. Because of its OO principles and the general paradigm of Java programming, like wrapping things in static variables, and having things return specific types, heavily aids me in "visualizing" a program. Instead of thinking of a big program, I can, instead, focus on smaller organized parts of my eventual program, and add functionality and build up from there. Thus, I have trouble programming in other languages. Or at least, I have not been able to program in the same ability as I do in Java compared to other languages. I know Javascript has OO principles, so I'd like to learn this language in a OO-based like I would program with Java. Is this possible?

  • Years experience over unfinished degree?

    - by Daniel Lewis
    I'm currently in my placement year and working for a great software development company. It was always my intention of getting to this stage through university, getting enough academic experience as well as the year’s placement and then try to get a full time programming job without the need to finish my degree. I decided this from an early stage as I have never really liked the whole university environment. I was so unhappy at university and I’m so happy now I’m on my placement year, I really don’t know if I can go back. My question is, do you think companies will take me on if I apply for other jobs after my placement year and not penalize me for not finishing my degree? I guess at the end of the day I don't want to look back on my life and think "god, why didn't I just spend one more year being unhappy to have a job I love" but I know that even if I get a degree I could still end up without a programming job and this worries me more than anything.

  • Is it normal to sometimes take a while to get even basic things working in software development?

    - by user1092719
    This is a little hard to explain because it's a really generic question, but bear with me... I find that when I am doing or recreating basic things from scratch (i.e. without the help of libraries), sometimes it feels as though I'm taking much more time to do the task than is actually needed. I am not new to programming or development & design concepts and have worked extensively with around 9 languages and various platforms and paradigms over 5/6 years. Although I don't yet have any academic qualification for programming and have learned almost exclusively from the Internet, I have been told that the quality of my code is excellent by those with qualifications. So, I don't think I'm a bad programmer because I really love doing it and working with software architecture, but maybe I'm slow? Or is it normal to take sometimes longer than it seems necessary to do basic tasks?

  • Handling (many) multiple projects in Git in an enterprise environment

    - by Michael K
    One of the advantages of older version control systems such as CVS and SVN in enterprise development is that anyone can connect to source control and see all the projects that the company has. This can make it easier to get a high level view of what kid of development is happening outside your sprint and also keeps everything in one place and easy to find. However, distributed version control systems (Git, specifically) use the repository as their base unit. They work best with one project (or several closely related projects) per repository. This makes repository management more difficult in most enterprise environments where it is not unusual to have more than 25-50 projects to support. As far as I have been able to determine, you have to keep a list somewhere else of all the repos you have. There is software available, like GitHub, that help, but that still is an extra step beyond a single connection string and listing the contents of the repository. What is the best way to deal with the complexity of multiple repositories?

  • Blocked Sites at work (that aren't even bad)

    - by Mercfh
    So here recently, i've been using google to look up information for basically random programming things (i was just hired on a month or so ago). So here recently I was actually looking up some information about RAW_SOCKETS (but thats beside the point) Anyways some of the tutorials sites/explaining how to use them and explaining the protocol sites are actually blocked. (and our manager sent out an email saying that if u run into a site just to email her just in case). Now obviously...w/e sys admins probably see these 'blocked' sites in their reports. But should I be worried? I mean....I literally am not trying to be devious Im just trying to learn stuff. I guess programming websites are sometimes labeled as "hacking". sometimes blogs get labeled like that, but alot of the time blogs have USEFUL information. This apparently happens alot of my other co-workers and they don't even bother emailing our manager.....but should I be worried? Or has this happened to you guys before?
