• Breaking into database administration

  - by user603794

  Hello to all, I am brand new on this site and look forward to interacting with each of you. I am graduating in June with my Bachelors Degree in Computer Information Systems with hopes of become a DBA in the future. I am currently taking a Database class now and studying SQL Server/T-SQL on the side. My experience in IT is limited to managing an Access database at my last employer for two years. What are the chances of landing a junior DBA position after I graduate?

• Static teams or dynamic teams?

  - by Richard DesLonde

  Is it better to assemble permanent teams of developers within the company that always work together, from project to project, or is it better to have dynamic teams that assemble for a project, and then dissasemble afterwards? My inclination is to treat the entire company as a "platoon" and to assemble "fireteams" for individual projects, choosing from the "platoon" those developers best suited for the project.

• Career Change Need Advice: Professional Web Developer

  - by bikedorkseattle

  I'm hoping to get some advice here on the steps I should take to make a career change into professional web development. I've been working in cancer research the last 14 years and I need a change. The job market is terrible, the pay is worse, and despite what one would think the atmosphere is generally un-collegial, even in your own group. Venture funding never returned after the dot com burst and with 3 to 5 wars our country is now in, NIH funding is only going to get worse. I know things are not going to get better for my field, sadly, and I know I need to move on. For probably just as long I have fiddled around with web development, I even run a fairly popular site with close to 1 million/month pageviews that pulls a decent income, but not stable enough to live off of right now. My skills are ok for being self taught. I enjoy the fast paced nature of the web and the tools the community creates and how eager people are to help and share knowledge; it's what science should be. I have been trying to find an entry level developer job doing standard HTML/CSS/PHP/MySQL/JS/jQuery type work. A good 50%+ of the jobs want someone with a CS degree, and most want 5 years experience. Having no professional experience and no formal education, I know I'm at a huge disadvantage. I am now considering my options on how to move forward professionally. The way I see it I have basically 3 options. Build up my portfolio of work as much as I can and continue to learn as much as I can on my own. Try to contribute on some open source project when time allows. Network like crazy and go to meetups. Be confident and pray a lot in private. OR While doing above, do some certification programs in PHP and Java, possibly others. Get a Zend Certification. OR Spend a few years getting a CS degree while doing 1. I've already done the work fulltime go to school thing and it doesn't excite me one bit. I didn't have the greatest college experience and am not too eager to return, but I have a family to feed. Is the degree really necessary or is it more of a right of passage type thing in most instances? I appreciate everyones input. Thanks for taking the time to respond.

• Memory Management/Embedded Management in C

  - by Sauron

  Im wondering if there is a set or a few good books/Tutorials/Etc.. that go into Memory Management/Allocation Specifically (or at least have a good dedicated section to it) when it comes to C. This is more for me learning Embedded and trying to keep Size down. I've read and Learned C fine, and the "standard" Learning books. However most of the books don't spend a huge amount of time (Understandably since C is pretty huge in general) going into the Finer details about whats going on Down Under. I saw a few on Amazon: http://www.amazon.com/C-Pointers-Dynamic-Memory-Management/dp/0471561525 http://www.amazon.com/Understanding-Pointers-C-Yashavant-Kanetkar/dp/8176563587/ref=pd_sim_b_1 (Not sure how relevant this would be) A specific Book for Embedded that has to do with this would be nice. But Code Samples or...Heck tutorials or anything about this topic would be helpful!

• How to unit test image processing code?

  - by rold2007

  I'm working in image processing (mainly OCR) and I wonder how I should integrate unit tests in my development. I'm already using unit tests for more "common" type of code but when dealing with image processing code I'm not sure how to deal with it. This kind of code always need some image data input/output and mocking this is not obvious. For now I'm mostly doing integration tests but they take a while to run and I would like some ideas on how to break down this kind of code into unit tests so that I can run them more quickly.

• Code while standing

  - by bgbg

  I have a regular, standard, workplace: a desk, a chair an LCD monitor, a mouse and a keyboard. I would like to have the ability to work while standing. I have the feeling that my employer will not will to buy an adjustable desk, instead of the existing one, so I would like to have your help with ideas on how to convert a workplace to a "standable" one on as low budget as possible. I saw this discussion, but the solutions proposed there are way above my "low budget" definition

• What common term could be used for Web Services, Windows Services etc

  - by Shamim Hafiz

  My question is primarily concerned with making a CV. Normally under the Language section we list the individual programming Languages we've used. For example, C#, C++, PHP. Under the Platform section we can list the various operating systems and devices. Under which category would Web Services/Windows Services fall? My point is these are not platforms by themselves and surely they aren't a language. Is there any common term that can be used to describe these?

• SQL Server DBA - How to get a good one!

  - by ETFairfax

  I'm a lone developer. I am currently developing an application which is seeing me get way way way out of my depth when it comes to SQL DBA'ing, and have come to realise that I should hire a DBA to help me (which has full support from the company). Problem is - who? This SO thread sees someone hire a DBA only to realise that they will probably cause more harm then good! Also, I have just had a bad experience with a ASP.NET/C# contractor that has let us down. So, can anyone out there on SO either... a) Offer their services. b) Forward me onto someone that could help. c) Give some tips on vetting a DBA. I know this isn't a recruitment site, so maybe some good answers for c) would be a benefit for other readers!! BTW: The database is SQL Server 2008. I'm running into performance issues (mainly timeouts) which I think would be sorted out by some proper indexing. I would also need the DBA to provide some sort of maintenance plan, and to review how our database will deal what we intend at throwing at it in the future!

• Is my concept in open source license correct?

  - by tester

  I would like to justify whether my concept in the open source license is correct, as you know that, misunderstanding the terms may lead to a serious law sue. Thank you. The main difference among the open source license is whether the license is copyleft. Copyleft license means allow the others to reproduce, modify and distribute the products but the released product is bound by the same licensing restriction. That means they have to use the same license for the modified version. Also, the copyleft license require all the released modified version to be free software. On the other hand, if any others create derived work incorporating non-copyleft licensed code, they can choose any license for the code. The serveral kinds of license and comparsion GPL is a restrictive license. Software requires to released as GPL license if that integrate or is modified from the other GPL license software . The library used in developing GPL license software are also restricted to GPL and LGPL , proprietary software are not allowed to employ (or complied with) in any part of the GPL application. LGPL is similar to GPL , but was more permissive with regarding allow the using of other non-GPL software. BSD is relatively simple license, it allow developer to do anything on the original source code . The license holder do not hold any legal responsibilities for their released product. Apache license is evolved from the BSD license. The legal terms are improved and are written by legal professionals in a more modern way. It covers comprehensive intellectual property ownership and liability issues. Also, are there any popular license beside these? Thank you

• What ethical problems realistically arise in programming?

  - by Fishtoaster

  When I co-oped during college, I had to fill out an evaluation of the co-op afterwards. One metric I always had to rate was how much the company required me to "Make ethical decisions related to your profession." This always seemed kinda silly- I mean, my first co-op was writing java apps to manage industrial radios. There wasn't much moral ambiguity going on. Anyway, I'm wonder what sort of ethical dilemmas one might actually encounter in software development. Edit: It should be noted that no ethically-trained software engineer would ever consent to write a DestroyBaghdad procedure. Basic professional ethics would require him to write a DestroyCity procedure, to which Baghdad could be given as a parameter. - Nathanial Borenstein

• Clarification of "avoid if-else" advice [duplicate]

  - by deviDave

  This question already has an answer here: Elegant ways to handle if(if else) else 21 answers The experts in clean code advise not to use if/else since it's creating an unreadable code. They suggest rather using IF and not to wait till the end of a method without real need. Now, this if/else advice confuses me. Do they say that I should not use if/else at all (!) or to avoid if/else nesting? Also, if they refer to the nesting of if/else, should I not do even a single nesting or I should limit it to max 2 nestings (as some recommends)? When I say single nesting, I mean this: if (...) { if (...) { } else { } } else { } EDIT Also tools like Resharper will suggest reformatting if/else statements. It usually concerts them to if stand-alone statement, and sometimes even to ternary expression.

• Modelling highly specific business requirements

  - by AndyBursh

  How can one go about modelling highly specific business requirements, which have no precedent in the system? Take for example the following requirement: When a purchase order contains N lines, is over X value in total and is being recorded against project Y, an email needs to be sent to persons A and B with the details This requirement supplements other requirements surrounding purchase orders, but comes in at a much later date in response to some ongoing problem elsewhere in the business. Persons A and B are not part of any role or group in the system, and don't hold any specific responsibility; they are simply the two people the business has appointed to receive these emails in this very specific case. Projects are also data driven, so project Y has no special properties to distinguish it from any other project. The only way to identify it is to compare its identifier to a magic number. How can one go about modelling this kind of case without introducing too much additional complexity? That I can think of right now, there are a couple of options. Perform the checks and actions inline with the existing code. Here we find the correct spot in the code, check the conditions in the requirement and send the emails to hardcoded addresses. Of course this is fraught with issues. At the very least it stops working if one of these people leaves or changes their email address. At worst you have to ensure that any tests and test data are aware that additional actions are taken for a specific set of criteria. Introduce some form of events system. Here we introduce an eventing system, so that we might react to some event, and fulfil the requirement outside of the usual path of execution. This sounds like a cleaner solution than option 1, but the work involved is ultimately probably slightly overkill for this one small requirement. That said, having it in place does allow the system to handle these kinds of specific requirements consistently and easily in the future. Are there any other (good/better) ways of handling highly specific requirements? I mean other than telling the other parts of the business no!

• Can an internally developed fast evolving, agile, short sprint web application lend itself to offshoring?

  - by Gavin Howden

  I have recently been set a target to achieve readiness to successfully manage and deliver results through the usage of offshore teams on our mainline development project within 12 months. Our mainline is a multi-thousand user highly available web application, and various related SAAS components delivered through the above mentioned web application. We work agile on the mainline with a rapid 1 week sprint using continuous integration. Our delivery platform is a bespoke php framework, although we have some .net services and components in the mix. My view is: an offshore team could work if we either ship out an entire isolated project for offshore development, or we specify a component for our system in huge detail up front. But we don't currently work like that, and it will conflict with the in-house method, and unless the off-shore is working within our team, with our development/deployment chain it could be an integration nightmare. So my question is, given we have a closed source bespoke framework (Private IP) which we train our developers to use, and we work agile minimising documentation, maximising communication and responding to rapidly changing requirements, and much of the quality control is via team skills building and peer review, how can I make off-shoring work on our main line development?

• Functional Programming - Does Knowing It Help Job Prospects?

  - by Jetti

  The main language that I use at the moment is C# and I am the most comfortable with it. However, I have started dabbling in F# and Haskell and really enjoy those langauges. I would love to improve my skills in either of those languages over time since it truly is fun for me to use them (as opposed to Ruby, which is hyped as "fun", I just don't get where the fun is, but I digress...). My question is directed at those who have hired/interviewed for programming positions (junior/mid-level): if you see a functional programming language on a resume, does it affect your opinion (whether positive or negatively) of that candidate? My rationale for knowledge of functional programming affecting the view of a candidate is because it can show that the candidate can adapt to different methodologies and take a mulit-dimensional approach to problems rather than the "same old OO approach". (This may be off-base, please let me know if this assumption is as well!)

• Forking project on Github etiquette

  - by Mike Wills

  There is a project on Github that I mostly like and want to use. There are a few things I want to do differently/remove that doesn't make sense for what I want/need. Also I want to add a few things as well. As I understand it, I should fork the project and I can make whatever changes I want and push back to my fork. From there, I also want to occasionally pull into my fork the changes from the original project so I get the latest bug fixes/features. Am I off-base of how I think it should work? How would bring in the changes from the original project?

• How should I manage my time?

  - by Tathagata

  There are times when just one bug that keeps eating away your time like hell ... for example this one. I generally end up wasting hours and realize I've gone terribly behind my schedule and not completed other tasks. With n number of tabs open in the browser, I end up posting the question in stackoverflow as a last resort. What are some time management techniques that lets you stop, rewind and get back in action when faced with a road block?

• What are the problems with a relatively large common library?

  - by Sam Pearson

  As long as the code in the base library is as loosely coupled as splitting it up into separate libraries, what's the problem? In general, having a lot of assemblies composing a .NET solution is painful. Plus, when code in one solution needs to be shared, it can just be added to the common library, rather than deciding which common library it should be added to or creating yet another library. edit: the question comes to me after using Smalltalk for a bit, where all the code is available to use, all the time.

• 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.

• Business person turned into coder? How and why? Inspire the non-technical.

  - by huisjames

  I graduated with a Business degree. Two years later, I finally realized the power of programming - the power to "invent." I wish I realized this in high school. Nevertheless, I tried to self-teach C# but found it difficult. Then I pivoted to learn PHP two months ago and I have been able to build things I thought was beyond my abilities. Has anyone had the same experience? Or self-taught programming? What lessons did you learn?

• Languages with similar features to JavaFX Script

  - by bunglestink

  I just completed a small project in JavaFX, only finding that it has been declared dead by Oracle. JavaFX Script actually seemed to be a pretty interesting language with some neat features for its domain, particularly with bind for data binding and on replace for triggered events. These features actually make the language very useful for small, quick, RIA type apps, which leads to my question: Are there any mainstream languages with features similar to bind and on replace? After working with JavaFX, I got some ideas for some small personal (academic) projects that could take advantage of these features, but I would prefer to not start anything new in a language considered extinct by its owners.

• 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.

• What is the best approach for database design with lots of columns?

  - by Pratyush

  I am writing a query based financial application. It lets the user to write complicated equations (much like WHERE part of an SQL query) and find companies matching those criteria. For the above, I currently have more than 500 columns in the database table (each column representing a financial field). Example of Columns are: company_name, sales_annual_00, sales_annual_01, sales_annual_02, sales_annual_03, sales_annual_04, protit_annual_00, profit_annual1...(over 500 such columns). The number of rows is around 5000. Going forward, I would like to further increase the number of columns/financial-fields. For the above I would like to get help regarding: 1) What is the best database design approach? Is it ok to have these many number of columns? 2) How can it be normalized? (User can use any of these fields in search criteria). 3) Is it ok to stick with MySQL, or modern document based databases like MongoDB should be better for it? P.S. (Update): I have been using MySQL till now and a running example of the usage is at: http://screener.in/companies/89/Formula-- In above there around 500 fields/columns to create your query on, however, I seek to increase that number to much more in future.

• DDD and validation of aggregate root

  - by Mik378

  Suppose an aggregate root : MailConfiguration (wrapping an AddressPart object). The AddressPart object is a simple immutable value object with some fields like senderAdress, recipentAddress (to make example simple). As being an invariant object, AddressPart should logically wrap its own Validator (by the way of external a kind of AddressValidator for respecting Single Responsibility Principle) I read some articles that claimed an aggregateRoot must validate its 'children'. However, if we follow this principle, one could create an AddressPart with an uncohesive/invalid state. What are your opinion? Should I move the collaborator AddressValidator(used in constructor so in order to validate immediately the cohesion of an AddressPart) from AddressPart and assign it to aggregateRoot (MailConfiguration) ?
