• What are the pre-requisites to become a Business Developer

  - by T.Raghavendra

  I am not sure if this is the right portal, But i believe many entrepreneurs are available here. I wanted to know how can someone get in to business development. what are the factors that are necessary if the person has no MBA degree. is it possible to get into such profession. I mean is it just the fact you must know how to write RFP, or estimates. Understanding client requirements and getting them the best available solution. Please guide me as I am interested, with 5+ years of industry experience is it possible to move to different domain.

• Security in API authentication

  - by Carlos

  We are in the process of revamping our server side API, and we need to manage security. Our current model requires that a credentials object (containing user, password, and pin) be included in each method invocation. Our development team, however, has decided that we should have session objects instead (which is fine by me), but the new credentials are just a GUID. This is very different from what I've seen in other APIs in our industry, so I'm a bit concerned about how secure the new model will be. I asked them if they had analyzed both alternatives, and they said they haven't. Does anyone know if there're any clear advantages, disadvantages, risks, etc. of using a set of credentials versus just one element (complex as it may be)? PS: the communication channel would be secure in either case, and it's separate from this particular topic

• Resources for finding Haskell jobs?

  - by Dan

  Where is a good place to go to find a job where I can (frequently) use Haskell? Just to be clear, I am not asking: What's the Haskell market like? Why is Haskell used so little in the industry? What is Haskell actually useful for? Nor am I asking you to tell me that Haskell jobs can't be found. That is the default conclusion if no good responses show up here. I am asking, for the 2 or 3 Haskell jobs that are out there, how can I find them?

• Nesting maximum amount of shapes on a surface

  - by Fuu

  In industry, there is often a problem where you need to calculate the most efficient use of material, be it fabric, wood, metal etc. So the starting point is X amount of shapes of given dimensions, made out of polygons and/or curved lines, and target is another polygon of given dimensions. I assume many of the current CAM suites implement this, but having no experience using them or of their internals, what kind of computational algorithm is used to find the most efficient use of space? Can someone point me to a book or other reference that discusses this topic?

• How much do politics/office intrigue interfere with your day to day tasks at work?

  - by Michael Dorgan

  I'm currently blessed to be employed at a location where politics are pretty much non-existant and management overhead is nearly nil. As I've only worked at this one location for my entire, lengthy career, I have very little frame of reference outside of an occasional Dilbert comic or offhand comment from others about just how bad office politics and management interference get in the way of getting your code done elsewhere. While I'm not actively looking for a new job, this one point has made me quite reluctant to even look seriously elsewhere. My question is, just how much are politics a way of life in larger companies - in or out of the game industry and how much does it affect your day to day satisfaction?

• What application domains are CPU bound and will tend to benefit from multi-core technologies?

  - by Glomek

  I hear a lot of people talking about the revolution that is coming in programming due to multi-core processors and parallelism, but I can't shake the feeling that for most of us, CPU cycles aren't the bottleneck. Pretty much all of my programs have been I/O bound in one way or another (database, filesystem, network, user interaction, etc.) for a very long time. Now I can think of a few areas where CPU cycles are a limiting factor, like code breaking, graphics, sound, some forms of simulation (weather, physics, etc.), and some forms of mathematical research, but they all seem like fairly specialized application domains. My general impression is that most programs are still I/O bound and that for most of our industry CPUs have been plenty fast for quite a while now. Am I off my rocker? What other application domains are CPU bound today? Do any of them include a large portion of the programming population? In essence, I'm wondering whether the multi-core CPUs will impact very many of us, and if so, how?

• Correct way to write /* and */

  - by billpg

  Hi everyone. I'd like to know, please, the correct way to write the symbols that the C family of languages use to begin and end comments. Before you all respond "a slash followed by an asterisk", I mean what's the correct way to write them on paper. (IE, How many points should the asterisk have? What angle should the slash be? etc) Everything I need so I can sit down and draw correct comment start and end symbols. Please note, I'm looking for the correct standard way. If there is no industry standard, please respond with "there is no standard" and I will accept that answer.

• What are annotations and how do they actually work for frameworks like Spring?

  - by Rachel

  I am new to Spring and now a days I hear a lot about Spring Framework. I have two sets of very specific questions: Set No. 1: What are annotations in general ? How does annotations works specifically with Spring framework ? Can annotations be used outside Spring Framework or are they Framework specific ? Set No. 2: What module of Spring Framework is widely used in Industry ? I think it is Spring MVC but why it is the most used module, if am correct or correct me on this ? I am newbie to Spring and so feel free to edit this questions to make more sense.

• Would you take a pay-cut to get a higher position?

  - by jonathanconway

  Say you're in a contracting developer role at a bank that pays well and will probably be extended. Then you get offered a permanent role at an IT solution provider as a Senior Developer/Technical Lead. Would you stick with the contracting, or go to the permanent role? The contract role: pays well will probably be extended provides finance industry experience is reasonably challenging, although I don't get much ownership over the projects The permanent role: pays less gives me technical lead/team lead experience- involves a range of websites for different clients, and I get to take ownership of projects much more challenging technically, as I have to "earn my stripes" within the team before I'll be given team lead responsibilities. If you were in this situation, would you take the pay-cut and go with the permanent role? Or would you continue contracting, and not feel like you might have missed out on something really good?

• Achieving AES-256 Channel Encryption with the .NET Compact Framework

  - by Ev

  Hi There, I am working on a business application where the clients are Windows Mobile 6.1 Professional devices. The server is a Java enterprise application. The industry working group recommends AES-256 encryption for client/server communications. This is necessary to gain certification. The encryption doesn't necessarily need to be channel encryption, it could be payload encryption. Channel encryption is preferable. The client and server communicate using SOAP/HTTP, which we are yet to implement. We plan to use WCF on the compact framework. In order to alleviate some of the work required to implement manual encryption/decryption, it would be nice if we could achieve the required encryption either at the TLS level, or somehow using the WS-* standards (I'm not particularly familiar with that group of technologies but I am learning right now). The server supports https with 256-bit AES. Does anybody have an idea on the best way to implement this? Thanks in advance.

• Will iPhone OS4 make your life easier or harder as a lone app developer?

  - by Matt

  I am interested to hear what people feel about the new iPhone OS4 release. It is obviously very exciting having access to all the new features, apparently (from apple.com) it has over 1500 new APIs. My original thoughts were "Wow, this is awesome", and I suppose it is. I was just getting comfortable with OS 3.2 development though, and now there is a raft of additional stuff to learn in order to keep up with the pack. So I am feeling quite frustrated! Do you think, when working as an individual app developer, having access to these additional features would improve your applications or just water down the quality? I guess being giving the opportunity to improve applications and provide better features should be welcomed. I think frustration comes from struggling to keep up with the continuous changes, but thats the industry we are in I suppose! Any thoughts/comments?

• Best tools / formats for documenting XML API?

  - by ivant

  We are developing XML over HTTP service and we need a way to document the XML interface. Our supported XMLs generally are subsets of some industry standard XML API, which unfortunately lacks any good documentation. It has XSDs though with some annotations, so we use this go generate the initial documentation and then remove the unsupported parts and refine the result. But this process is tedious and the results aren't at all great. Any suggestion about documentation formats and tools? I prefer to have HTML output and possibly more, e.g. PDF. Oh, and we are mixed Linux and Windows shop, so the tools should work well on both.

• Data Warehouse: One Database or many?

  - by drrollins

  At my new company, they keep all data associated with the data warehouse, including import, staging, audit, dimension and fact tables, together in the same physical database. I've been a database developer for a number of years now and this consolidation of function and form seems counter to everything I know. It seems to make security, backup/restore and performance management issues more manually intensive. Is this something that is done in the industry? Are there substantial reasons for doing or not doing it? The platform is Netezza. The size is in terabytes, hundreds of millions of rows. What I'm looking to get from answers to this question is a solid understanding of how right or wrong this path is. From your experience, what are the issues I should be focused on arguing if this is a path that will cause trouble for us down the road. If it is no big deal, then I'd like to know that as well.

• Where can I find the transaction protocol used by Automated Teller Machines?

  - by Dave

  I'm doing a grad-school software engineering project and I'm looking for the protocol that governs communications between ATMs and bank networks. I've been googling for quite a while now, and though I'm finding all sorts of interesting information about ATMs, I'm surprised to find that there seems to be no industry standard for high-level communications. I'm not talking about 3DES or low-level transmission protocols, but something along the lines of an Interface Control Document; something that governs the sequence of events for various transactions: verify credentials, withdrawal, check balance, etc. Any ideas? Does anything like this even exist? I can't believe that after all this time the banks and ATM manufacturers are still just making this up as they go. A shorter question: if I wanted to go into the ATM software manufacturing business, where would I start looking for standards?

• Browser Compatablitiy, Support, Modern Browsers and older Versions.

  - by smoop

  This is a question to all web-developers working in the industry more than a few years. Today the server guy at my work told me that his browser didnt render a google font I used on a site properly, so I checked his browser - it was firefox 3.5. (google font Raleway).. This made me think.. I know for some of our sites its a requirement to support IE6 (larger corperate sites) but for the rest (personal sites) should I be looking at developing for all incrments of firefox, chrome, IE and safari???? Does your company still support IE6? Does your company support previous versions of modern browsers or just the latest ones? and finally, has anyone else had this problem with FF 3.5 and Google Hosted font Raleway..(the font displays extra extra thing so the font is almost unreadable) If anyones interested I found a working solution to my font problem here: http://www.jshsolutions.net/google-webfonts-cross-browser-fix-howto/ Sam

• Flow Based Programming

  - by Software Monkey

  I have been doing a little reading on Flow Based Programming over the last few days. There is a wiki which provides further detail. And wikipedia has a good overview on it too. My first thought was, "Great another proponent of lego-land pretend programming" - a concept harking back to the late 80's. But, as I read more, I must admit I have become intrigued. Have you used FBP for a real project? What is your opinion of FBP? Does FBP have a future? In some senses, it seems like the holy grail of reuse that our industry has pursued since the advent of procedural languages.

• Would the world be a better place if there were only one programming language?

  - by Simon

  Well, perhaps not the world, but would it encourage more-re-use, less replication of basic code, or at least an uplift in what is considered basic code, more time advancing the application science and a greater encouragement to share, a more advanced base of understanding for new programmers, since the language could be taught ubiquitously and patterns of teaching would have emerged which were optimised for students learning etc etc? I think all of those things would make the programming world better and would probably have significant commercial benefit too. This is definitely not a religious debate about which language is best, and is predicated on the notion of some super-being having designed the perfect language to start with, which was improbable, but it strikes me that if, from the beginning, there were only a single programming language we may be further along in terms of the evolution of the software industry and software science. And although it is now impossible, if you buy some or all of these assertions is there an argument for standardising on a single language for the future so we can accelerate our collective progress rather than all of us re-inventing some part of the same wheel and consigning our children to the same fate?

• What are the flavor-of-the-month technologies that have now become obscure?

  - by Andreas Grech

  For this question, I am looking for programming languages, technologies and standards that where considered as a flavour-of-the-month in their prominent time but have since been forgotten in today's programming world. Also, with what have they been replaced? I am relatively new to the software development industry compared to most of the people here (with just only 5 years of experience), and from this question I am looking to learn about some of the now-obscure technologies that have been around during your time. Just for clarification, what I mean by flavour-of-the-month is technologies that had been extensively in their time but today have become obscure and forgotten; maybe replaced by other better ones

• What is a good way to quantify C++ knowledge and skill?

  - by LoudNPossiblyRight

  I have only recently started to study (with the hopes of mastering) C++, one because i have started to love it and two because it's a good career/profession move. At the same time i wish to quantify my knowledge and skill so as to set my self apart from those who just throw C/C++ on their resumes and fish. Is there an open, industry and community recognized way of quantifying ones knowledge and skill in C++? I have looked at Brainbench, MS C++ certificates, and other online certification sites which offer to rate you at $50-$200 per test however there doesn't seem to be a standard on how to rate knowledge and skill. It's one thing for MS or Oracle/Sun to have certifications for their products but C++ is a standard, shouldn't there be a standard way or rating one's knowledge and skill there in? Thanks.

• Error Exception 2048 on my website using OpenClassifieds software

  - by Rich Baxter

  I have a website called e-waitress.net, it is a jobs employment website for the restaurant industry. I installed an open source program called OpenClassifieds and a couple days after installing the OpenClassifieds, I get an error message when I enter my url that is this: ErrorException [ 2048 ]: date_default_timezone_get(): It is not safe to rely on the system's timezone settings. You are required to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'America/New_York' for 'EDT/-4.0/DST' instead ~ APPPATH/ko322/classes/kohana/date.php [ 592 ] I am wondering is this a server issue with my host provider or is it within the OpenClassifieds installation software? I've reinstalled the software twice and it's returned this error after a couple days of working great. Any ideas?

• Books on data-intensive enterprise integration patterns

  - by Tristan

  I'm trying to understand design patterns used by data-intensive enterprise applications. A classic example is the financial industry, where system must consume, analyze, and execute on real-time financial data while providing information and configuration options to a broad set of traders and analysts. One can imagine similar system in airlines, major supply chain operations, and utility providers. Are there good books that provide and inside view of how these systems work? Enterprise Integration Patterns is one example, but I'm looking for something with more real-world applications, particularly in finance.
