• How do you put a database online?

  - by Dezrik

  I have a very beginner question regarding web development. I've had some experience with JSP, Hibernate, and MAMP to create a simple system for tracking inventory and sales. But this was all done locally on one computer. This time, I want to create a system that could be accessible online. It's to help my mother track her business wherever she goes. So there would be similar aspects like tracking inventory and sales. I understand that you have to have a server in which to host all the files in. But I don't understand how you can access your database online. Or what sorts of applications or products should be used. Currently the host of my database is localhost. How do put it online such that you can still do CRUD operations? Are there any guides to do this?

• Hiring Developers - Any tips on being more efficient?

  - by DotnetDude

  I represent a software company that is in process of building a large software development team. We are picky in who we hire and have really good retention rate (most of the devs have been here for an average of 5-6 years). We've been spending a lot of developers' and HR time and have a low applications to hire ratio. Here's the process we use: HR Interview on phone - Involves asking basic behaviorial and tech questions Online test - Involves a 30 minute technical test Technical Phone interview - A 60 minute interview by a developer Onsite Interview - A 60-90 minute interview by several senior developers Although this process has been working, we've been spending way too much time on interviews. Any thoughts on how this can be done differently? Our goal is to automate any tasks if possible still retaining the quality of talent.

• What can programmers learn from the construction industry?

  - by Renesis

  When talking with colleagues about software design and development principles, I've noticed one of the most common sources for analogies is the construction industry. We build software and we consider the design and structure to be the architecture. One of the best ways to learn (or teach) are through analyzing analogies - what other analogies can be drawn from construction? (whether already in common use in software or not). Please provide a description, or your personal experience, regarding how the programming concept is similar to the construction concept. [Credit to Programming concepts taken from the arts and humanities for the idea]

• Paying a developer in stock/fixed rate? [closed]

  - by user51648

  I have an idea for a cross platform application. It will require knowledge of several different languages, web development, and system administration/IT. I don't personally code, but I want to pay professionals to do it. I'm wondering how I should go about paying them. Yes, this will be a large project, but I want it done ASAP. Is it ok if I don't pay them by the hour? I really want it to be a set price. Also, is it reasonable to pay them in stock of the company? Like, 20%? P.S. How do I know how big a project will be in order to give the devs themselves an idea?

• Developing a new complex travel website

  - by Kay

  We need to develop a completely new website for customers to choose a travel product with a contract. It needs to interface to our inventory to take the conference facility, hotel rooms etc. out of inventory once a contract has been signed (e-signature) and deposit paid. If you were starting from scratch, would you in-house or contract? If in-house, what development tools should I evaluate primarily - sharepoint, ASP.net? We are a small IT shop but we could hire 1-2 developers for this. We need to get something up in 12-18 months.

• Analysing Group & Individual Member Performance -RUP

  - by user23871

  I am writing a report which requires the analysis of performance of each individual team member. This is for a software development project developed using the Unified Process (UP). I was just wondering if there are any existing group & individual appraisal metrics used so I don't have to reinvent the wheel... EDIT This is by no means correct but something like: Individual Contribution (IC) = time spent (individual) / time spent (total) = Performance = ? (should use individual contribution (IC) combined with something to gain a measure of overall performance).... Maybe I am talking complete hash and I know generally its really difficult to analyse performance with numbers but any mathematicians out there that can lend a hand or know a somewhat more accurate method of analysing performance than arbitrary marking (e.g. 8 out 10)

• Some Insight on the Field of Knowledge Representations

  - by picmate

  I started following an MS in computer sciences after about two years of work for a software company. I worked primarily in data warehousing and business intelligence related software development during my previous occupation. There is a high chance for me to select a research in knowledge representations, ontologies and reasoning, as there are no other research available in any other interesting fields, such as pattern recognition and navigation. I developed an interest towards knowledge representation with what I learnt from the courses I am taking currently. But I do not have a deep understanding of it in terms of which areas such a field would have an impact in a real life scenario, and how it will help me when I am hunting for a job in the near future. Some thought about this would be greatly appreciated.

• How to chose a develop method?

  - by Martin

  There are many academic/industrial researchs about various development methods (Scrum, XP, waterfall, ect.), telling us how to do it right and stuff. But I never saw something that suggest how to choose a method, what will be better for a given project. I know that what the developers are used to is an very important aspect. But lets say that I am assembling a new group from scratch, and that every programmer in the world is willing to work with me. :) What aspects of the project should I consider to decide between Scrum, XP, TDD, ect.? Or is that an entirely human thing, regardless of what is being developed? I said that all programmers are available, but you may comment they're knowledge about the domain, or other characteristics in the answers. E.g. "If you chose to hire people with no domain knowledge, MethodX is better than MathodY, beacause ...." is a completely welcomed answer.

• What is the most effective way to add functionality to unfamiliar, structurally unsound code?

  - by Coder

  This is probably something everyone has to face during the development sooner or later. You have an existing code written by someone else, and you have to extend it to work under new requirements. Sometimes it's simple, but sometimes the modules have medium to high coupling and medium to low cohesion, so the moment you start touching anything, everything breaks. And you don't feel that it's fixed correctly when you get the new and old scenarios working again. One approach would be to write tests, but in reality, in all cases I've seen, that was pretty much impossible (reliance on GUI, missing specifications, threading, complex dependencies and hierarchies, deadlines, etc). So everything sort of falls back to good ol' cowboy coding approach. But I refuse to believe there is no other systematic way that would make everything easier. Does anyone know a better approach, or the name of the methodology that should be used in such cases?

• What does mathematics have to do with programming?

  - by Rory

  I just started a diploma in software development. Right now we're starting out with basic Java and such (so right from the bottom you might say) - which is fine, I have no programming experience apart from knowing how to do "Hello World" in Java. I keep hearing that mathematics is pertinent to coding, but how is it so? What general examples would show how mathematics and programming go together, or are reliant on one another? I apologize of my question is vague, I'm barely starting to get a rough idea of the kind of world I'm stepping into as a code monkey student...

• What are the downsides of leaving automation tags in production code?

  - by joshin4colours

  I've been setting up debug tags for automated testing of a GWT-based web application. This involves turning on custom debug id tags/attributes for elements in the source of the app. It's a non-trivial task, particularly for larger, more complex web applications. Recently there's been some discussion of whether enabling such debug ids is a good idea to do across the board. Currently the debug ids are only turned on in development and testing servers, not in production. There have been points raised that enabling debug ids does cause performance to take a hit, and that debug ids in production may lead to security issues. What are benefits of doing this? Are there any significant risks for turning on debug tags in production code?

• Web.NET is Closing Fast

  - by Chris Massey

  The voting for sessions has now closed, and sadly only half of the potential sessions could make it through. On the plus side, the sessions that floated to the top look great and, with the votes in, Simone and Ugo have moved right along and created a draft agenda to whet our appetites. Take a look, and let them know what you think. I’d also strongly recommend that you get ready to grab your tickets when they become available next week (specifically, September 18th), as places are going to be snapped up fast. In case you need a reminder as to why Web.NET is worth your time: Complete focus on web development Awesome sessions All-night hackathon Free (although I urge you to make a donation to help Simone and Ugo create the best possible event) Put October 20th in your calendar, and start packing. I’ve already booked my flights, and am perusing the list of hotels while I eat my lunch. Bonus Material There will be a full day of RavenDB training on Monday the 22nd of October, run by Ayende himself, and attending Web.NET will get you a 30% discount on the cost of the session.

• Best book for developer who needs to learn software fundamentals

  - by tharrison

  I have recently inherited a team of developers, none of whom really have any programming experience. Some are really bright, and are learning on their own. I am looking for one or two books that are practical but show the core practices of professional development: Structure, OO, naming, DRY, why elegance matters, etc. When I was learning, I loved Code Complete, and Programming Pearls, but they are dated now. Any recommendations for good books that could be used in tandem with a language specific book to help understand? Thanks in advance!

• I studied electrical engineering. Can I work as a developer? [closed]

  - by FailedDev

  A while ago I finished my Msc in Electrical Engineering and started working as an engineering consultant where I mostly do development work. I am good at picking up languages/technologies tools. I have fiddled with C/C++/C#/perl/ant/bash/html/css etc. Although I have never had a complain for my work, rather the contrary, I just feel that some day, someone will ask me a real hard task which would maybe seem rather trivial for a computer scientist but hard for me. Should I read/do something to become a better developer. Should I pick up a book about design patterns or algorithms for example? Is this normal that I have this kind of "fear"? Sorry if this is the wrong place to post this question. Please notify me so I can close it if this is the case.

• Is there a sequence to read through the Android Developer Site for a user new to Android?

  - by Paul

  I keep seeing that I don't need to buy an android development book, that I should just read the Android Developer Site site because it has everything I need to know. I see it more as drinking from a fire hose. But I'm one of those people who likes to be walked thru the basics. I like to build up my knowledge, rather than being dropped into reference documentation. I also like to make sure I have see all/most of the topics covered. I'd hate to develop the wrong thing because I don't know about Fragments, Content Providers, or whatever. So, since it's a great resource, better than any book (we don't need no stinkin books), how do I traverse the site to get the information provide in the same way as a book would lay it out?

• What types of programming require practical category theory?

  - by Alexander Gruber

  Category theory has applications in theoretical computer science and obviously is central to abstract mathematics. I have heard that it also has direct practical applications in programming and software development. What type of programming is practical category theory necessary for? What do programmers use category theory to accomplish? Please note my use of "necessary" and "require" in this post. I realize that in some sense most programmers will benefit from having experience in different types of theories, but I am looking for direct applications where the usage of category theory is essential, i.e. if you didn't know category theory, you probably couldn't do it. Also, I'd like to clarify that by "what type of programming," I am hoping less for a broad answer like "functional programming," and more for specific applications like "writing bank software" or "making operating systems."

• Working on a virtual machine as a developer

  - by Johnny000

  In the company I'm currently working in, they decided that each developer will move to a VM desktop (Citrix/WinServer2012) an develop/test from there with restricted/no rights to install new software. The Server we will be working on are in a remote Datacenter. So i.e. if for some reason or another the internet brake down, we can't work till the connection is up again. As a developer I don't want to use windows as OS for my working/development environment as there is no need because we don't develop OS specific software. What good points could I raise in an argumentation against moving to the VMs beside the loss/restriction of freedom and the loss of connection to the internet?

• Hard Copies VS Soft Copies

  - by Garet Claborn

  Where do you draw the line and say, "OK, I'm actually going to print out this piece of code, spec, formula, or other info and carry it around but these pieces can stay on disk." Well, more importantly why do you draw the line there? I've encountered this a number of times and have some sort of vague conceptions beyond "oh now I'm REALLY stuck, better print this out." I've also found some quicksheets of basic specs to be handy. Really though, I have no particular logic behind what is useful to physically have available in the design and development process. I have a great pile of 'stuff' papers that seemed at least partially relevant at the time, but I only really use about a third of them ever and often end up wishing I had different info on hand. Edit: So this is what I'm hearing in a nutshell: Major parts of the design pattern Common, fairly static and prominently useful code (reference or specs) Some representation of data useful in collaborating or sharing with team Extreme cases of tough problem solving Overwhelmingly,almost never print anything.

• How much should I charge for a web app

  - by Kostas

  I am a freelance web developer and I am working on a PHP/MySQL/Javascript based project. It's a web app that uses a custom CMS with user types, followers system, search forms, blogs, social integration. It will take about 3 months to finish, according to a roadmap I make (based on current development stage) and about a month after that for bug fixing and testing. So I have to tell them a price. What price range you think it's appropriate?? (It's a good regular client, so I want something reasonable) Can you give me some ideas?? Thanks.

• 'Situations gone wrong' for web apps...

  - by AvgJoe007

  Hi all I know there's some decent material floating around relating to more specific areas, but wanted to get some opinions from people who have had bad experiences in the past. I have a project where I can have a say on the design of a B2C web app, which has some external API interfaces. UX is crucial as is speed. Not sure what technology will be used at this stage. In designing this application, I want to make sure obvious features are not left out (i.e. ones that make maintenance/development easier). So can you guys tell me about 'situations gone wrong' that could have been avoided had more consideration taken place? Am looking to gather feedback in general, so don't worry if your example is industry/technology specific - so long as it pertains to web. Thanks for reading, I look forward to your responses!

• What could be a reason for cross-platform server applications developer to make his app work in multiple processes?

  - by Kabumbus

  So we consider a server app development - heavily loaded with messing with big data streams.An app will be running on one powerful server. a server app shall be developed in form of crossplatform application - so to work on Windows, Mac OS X and Linux. So same code many platforms for standing alone server architecture. We wonder what benefits does distributing applications not only over threads but over processes as wall would bring to programmers and to server end users and why? Some people sad to me that even having 48 cores, 4 process threads would be shared via OS throe all cores... is it true BTW?

• Suggestions for Future or On-The-Edge Languages (2011)

  - by Kurtis

  I'm just looking for some suggestions on newer languages and language implementations that are useful for string manipulation. It's now 2011 and a lot has changed over the years. Most of my work includes web development (which is mostly text-based) and command line scripting. I'm pretty language agnostic, although I've felt violated using PHP over the years. My only requirements are that the language be good at text manipulation, without a lot of 3rd party libraries (core libraries are okay, though), and that the language and/or standard implementation is very up to date or even "futuristic". For example, the two main languages I'm looking at right now are Python (Version 3.x) or Perl (Version 6.x). Research, Academic, and Experimental languages are okay with me. I don't mind functional languages although I'd like to have the option of programming in a procedural or even object oriented manner. Thanks!

• It's hard to judge your own product. Is there a name for this issue?

  - by Epicmaster

  I was just talking to my partner about how hard it is to personally judge how good your product is after a while because you use it so often. You literally spend hours on your computer doing nothing but work on this Consumer Facing application, and you start to feel a little fatigue of using it over and over and over, at least a hundred times a day. You get scared this fatigue may mean the product you are building may have the same effect on the users and might mean you are doing something wrong. Is there a name for this in product development? For the fact that as a designer+ programmer+everything else, your product might not suck as much as you think simply because you spend way too much time with it, or a variation of this?

  - by bas-brain

  I need help on developing a UI for a app. Basically this app will have do panels, left and right, lets say. On the left panel will be displayed customers and when I click on the customer name on the right will appear tabs with information, some kind of form with name, email, picture, etc. I already developed the left panel with DictionaryGrid which I could found on tutorials and so on, but no idea on the right panel which is the form side. Any help??? Just the idea and the development is with me, thanks very much

• Is there a good tutorial/book for creating a quiz app for iOS 5? [closed]

  - by NRUTA

  I am new to iOS development and looking to create a quiz application which will be for ipad, iphone and itouch. It will ask a question, text based, and have four possible answers. After you select an answer, the system tells you if you are right or wrong and provides an explanation. It provides the percentage of correct answers. I'm not sure how to go about creating this and wondered if anybody has read a book, seen a tutorial or could offer any advice that would explain this process? Thanks in advance for all of your help!
