• What would you do to improve the working of a small Development team?

  - by Omar Kooheji

  My company is having a reshuffle and I'm applying for my boss' job as he's moved up the ladder. The new role would give me a chance to move our development team into the 21st century and I'd like to make sure that: I can provide sensible suggestions in the interview to get the job so I can fix the team If I get the job I can actually enact some changes to actually improve the lives of the developers and their output. I want to know what I can suggest to improve the way we work, because I think it's a mess but every time I've suggested a change it's been shot down because any time spend implementing the change would be time that isn't spent developing software. Here is the state of play at the moment: My team consists of 3-4 developers (Mainly Java but I do some .Net work) Each member of the team is usually works on 2-3 projects at a time We are each responsible for the entire life cycle of the project from design to testing. Usually only one person works on a project (Although we have the odd project that will have more than one person working on it.) Projects tend to be bespoke to single customer, or are really heavilly reliant on a particular customer environment. We have 2-3 "Products" which we evolve to meet customer requirements. We use SVN for source control We don't do continuous integration (I'd like to start) We use a really basic bug tracker for internal issue tracking (I'd like to move to an issue/task management system) Any changes that bring a sudden dip in revenue generation will probably be rejected, the company isn't structured for development most of the rest of the technical team's jobs can be broken down to install this piece of hardware, configure that piece of hardware and once a job is done it's done and you never have to look at it again. This mentality has crept into development team because it's part of the company culture.

• Is it a "pattern smell" to put getters like "FullName" or "FormattedPhoneNumber" in your model?

  - by DanM

  I'm working on an ASP.NET MVC app, and I've been getting into the habit of putting what seem like helpful and convenient getters into my model/entity classes. For example: public class Member { public int Id { get; set; } public string FirstName { get; set; } public string LastName { get; set; } public string PhoneNumber { get; set; } public string FullName { get { return FirstName + " " + LastName; } } public string FormattedPhoneNumber { get { return "(" + PhoneNumber.Substring(0, 3) + ") " + PhoneNumber.Substring(3, 3) + "-" + PhoneNumber.Substring(6); } } } I'm wondering people think about the FullName and FormattedPhoneNumber getters. They make it very easy to create standardized data formats throughout the app, and they seem to save a lot of repeated code, but it could definitely be argued that data format is something that should be handled in mapping from model to view-model. In fact, I was originally applying these data formats in my service layer where I do my mapping, but it was becoming a burden to constantly have to write formatters then apply them in many different places. E.g., I use "Full Name" in most views, and having to type something like model.FullName = MappingUtilities.GetFullName(entity.FirstName, entity.LastName); all over the place seemed a lot less elegant than just typing model.FullName = entity.FullName (or, if you use something like AutoMapper, potentially not typing anything at all). So, where do you draw the line when it comes to data formatting. Is it "okay" to do data formatting in your model or is that a "pattern smell"? Note: I definitely do not have any html in my model. I use html helpers for that. I'm strictly talking about formatting or combining data (and especially data that is frequently used).

• Is the term "web portal" obselete?

  - by John Hamelink

  Firstly, sorry if this is the wrong place: I've looked at all the programming-related boards and this one seems like the best fit - correct me if I'm wrong. My boss uses the term "portal" for the project I work on all the time. To me, the word makes me think of Yahoo in the late 90s. Does the word "portal" have old-school connotations, or is it just me? Do you think it's ok to use it, and not drag our client's perception of the product down into the middle-ages? Or again, am I just being weird?

• How to approach people you've found through internet with similar programming interests?

  - by randomguy

  I've recently really dived into Ruby/Rails and I'm falling in love. I have a gut feeling this might be something that could last for a while. What I've been missing is interaction with people who are as passionate about Ruby, Rails and things closely related to these. I live in a relatively small city, but was able to find five local people through a RoR website. Weekly meetups with Macs, beer and bro-love rushed through my mental theater. Seriously though, I have no clue how I could approach these people. I have their e-mail addresses. Any advice?

• Algorithm for a lucky game [on hold]

  - by Ronnie

  Assume we have the following Keno(lottery type) game: From 80 numbers(from 1 to 80), 20 are being drawn. The players choose 1 or 2 or 3..... or 12 numbers to play(12 categories). If they choose for example 4 then they win if they predict correctly a certain amount of numbers(2,3 or 4) from the 4 they have played and lose if the predict only 1 or 0 numbers. They win X times their money accordingly to some predefined factor depending on how many numbers they predict from each category. The same with the other categories. And e.g 11 out of 11 gives 250000 times your money and 12 out of 12 gives 1000000 your money. So the company would want to avoid winnings so high. Every draw by the company is being made every 5 minutes and in each draw around 120000 (let's say) different predictions(Keno tickets) are being played. Let's assume 12000 are being played in category 10 and 12000 in category 11 and also 12000 in category 12. I'm wondering if there is an algorithm to allow the company that provides the game in the 5 minutes between the drawings, to find a 20 number set, in order to avoid any "12 out of 12" and "11 out of 11" and "11 out of 12" and "10 out of 11" and "10 out of 10" winning ticket. That means is there any algorithm, where in a time of less than 1 minute approximately(in todays hardware), to be able to find a 20 number set so that none of the 12000 12 and 11 and 10 number sets that the players played(in categories 10,11 and 12) contains any winning of "12 out of 12" and "11 out of 11" and "11 out of 12" and "10 out of 11" and "10 out of 10"? Or even better the generalization of the problem: What is the best algorithm(from a perspective of minimal time), to be able to find a Y number set from numbers 1 to Z(e.g Y=20, Z=80) so that none of the X sets of K-numbers that are being played(in category K) contains more than K-m numbers from the Y-set? (Note that for Y=K and m=1 there is a practical algorithm.)

• So what *did* Alan Kay really mean by the term "object-oriented"?

  - by Charlie Flowers

  Reportedly, Alan Kay is the inventor of the term "object oriented". And he is often quoted as having said that what we call OO today is not what he meant. For example, I just found this on Google: I made up the term 'object-oriented', and I can tell you I didn't have C++ in mind -- Alan Kay, OOPSLA '97 I vaguely remember hearing something pretty insightful about what he did mean. Something along the lines of "message passing". Do you know what he meant? Can you fill in more details of what he meant and how it differs from today's common OO? Please share some references if you have any. Thanks.

• Computer Science Programming Certificate vs. Computer Science Degree?

  - by Jess

  I'm kind of in a tough spot. My current living conditions require that I work a full-time job while attending school. I've attended a UC in the past but had to withdraw my junior year due to financial issues at home. I currently work an entry-level IT corp job but I'm looking to further my salary/skills by getting a degree, or a programming certificate like this one: http://www.lavc.edu/voced1/CSITCertCSP/CSITCertFrameCSP.htm Herein lies the problem. I prefer getting a CS degree from an accredited university but I looked at the schedules for classes and it is impossible to work around my current 40/hr work week. There are random morning classes, with the occasional evening class, but the times get even more construed as I move my way up to the upper divisions. So what I guess I'm trying to get at is, can anyone lay out the pros and cons of obtaining a certificate vs. the degree (besides obvious points like the latter being 100x better)? I'm aware that having a degree is always going to be a better route, but...is the programming certificate useless? Should I not even bother?

• What to use for simple cross-platform games instead of Flash?

  - by jmh_gr

  In short, for simple games: Is Flash still a good option for browser-based PC clients? It still has 90%+ penetration. What is a good alternative for mobile devices? It HTML5 + JavaScript the choice for mobile? Or does one have to learn a new native language for each target platform? (Android, Apple, Windows Phone)... If you desire further background: There are more blogs about the official demise of mobile Flash than I can count, along with endless useless and vitriolic comments. I'm actually trying to do something practical: build simple games that can be served accross multiple platforms. Several months ago I plopped down $1100 for CS5.5 Web and am wading into Flash. Bummer. My question to people who actually develop simple games and apps: What platform should I use instead? Is Flash still a sensible platform for web-served PC users? For example, let's say I build a simple arcade game that I would like to serve as an app to mobile users and as a browser-based game to PC users. Should I still invest the time and effort to learn and develop in Flash for the PC users, while building a parallel code set in some other language for mobile users? My games are simple enough that it would be annoying but not inconceivable to maintain parallel code sets.

• Defensive Programming Techniques.

  - by Pemdas

  I was attempting to identify an element of software engineering that I think is overlooked, not emphasized or not taught in typical undergraduate course work for CS or SE. What I came up is the concept of defensive programing. I would like to hear the communities options on defensive program and/or specific techniques that you use on a regular basis. Also, I would to know if there are any language specific techniques.

• Mobile Apps for Hospitals?

  - by Joey Green

  I currently work for a pretty large hospital and have been dabbling in iPhone development for a couple years. The CEO is wanting to get together a group to see what mobile technology we could create. I was contacted to be the main developer. I wanted to gather some ideas of what kind of mobile apps people have seen deployed in hospitals. Not necessarily medical apps that you can get on the app store, but rather apps built specifically for a hospital. Any ideas? If this is not the appropriate forum for a question like this, can someone point me to a forum where it would be appropriate?

• Architecture of interaction modes ("paint tools") for a 3D paint program

  - by Bernhard Kausler

  We are developing a Qt-based application to navigate through and paint on a volume treated as a 3D pixel graphic. The layout of the app consists of three orthogonal slice views on which the user may paint stuff like dots, circles etc. and also erase already painted pixels. Think of a 3D Gimp or MS Paint. How would you design the the architecture for the different interaction modes (i.e. paint tools)? My idea is: use the MVC pattern have a separate controler for every interaction mode install an event filter on all three slice views to collect all incoming user interaction events (mouse, keyboard) redirect the events to the currently active interaction controler I would appreciate critical comments on that idea.

• force recompilation of war file including its Jar dependencies

  - by Mik378

  I have a project A (a webapp), depending on project B (B.jar) and this one depending on project C (C.jar). I would like to create a maven goal named "Rebuild War", that clean all compiled code for these 3 projects and rebuild the whole in order to obtain a fresh War file. I tried mvn clean package on project A, but I noticed that B and C are not recompiled. Indeed, B.jar and C.jar that are contained in local repository don't have a changing creation date. Is there an adapted maven command for this requirement ?

• How to become an expert web-developer?

  - by John Smith

  I am currently a Junior PHP developer and I really LOVE it, I love internet from first time I got into it, I always loved smartly-created websites, always was wondering how it all works, always admired websites with good design and rich functionality, and finally I am creating web-sites on my own and it feels really great. My goals are to become expert web-developer (aiming for creating websites for small and medium business, not enterprise-sized systems), to have a great full-time job, to do freelance and to create my own startup in future. General question: What do I do to be an expert, professional and demanded web-programmer? More concrete questions: 1). How do I choose languages and technologies needed? I know that every web-developer must know HTML+CSS+JS+AJAX+JQuery, I am doing some design aswell cause I like it and I need it for freelance also. But what about backend languages? Currently I picked PHP cause it's most demanded in my area and most of web uses it, but what would happen in future? Say, in 3 years, I am good at PHP and PHP frameworks by than, but what if some other languages get most popular? Do I switch to them? I know that good programmer is not about languages and frameworks but about ability to learn and to aim the goals, but still I think that learning frameworks for some language can take quite some time. Am I wrong? 2). In general, what are basic guidelines to be expert web-developer? What are most important things I should focus on? Thank you!

• Is Google Closure a true compiler?

  - by James Allardice

  This question is inspired by the debate in the comments on this Stack Overflow question. The Google Closure Compiler documentation states the following (emphasis added): The Closure Compiler is a tool for making JavaScript download and run faster. It is a true compiler for JavaScript. Instead of compiling from a source language to machine code, it compiles from JavaScript to better JavaScript. However, Wikipedia gives the following definition of a "compiler": A compiler is a computer program (or set of programs) that transforms source code written in a programming language (the source language) into another computer language... A language rewriter is usually a program that translates the form of expressions without a change of language. Based on that, I would say that Google Closure is not a compiler. But the fact that Google explicitly state that it is in fact a "true compiler" makes me wonder if there's more to it. Is Google Closure really a JavaScript compiler?

• Real-world use cases for Smalltalk

  - by Andrea Spadaccini

  Hello, I've been playing a bit with Smalltalk, and I found it interesting. I know that there are some classical examples of Smalltalk: the Smalltalk images themselves and the Seaside web framework, and that there are lots of in-house custom applications built using this language. I'd like to know if: there are computer applications actively used and developed apart from the ones I mentioned. there are software houses that use Smalltalk for doing their job when would you use Smalltalk instead of another language for developing from scratch a new application

  When I put my USB drive into a computer, I want autorun.inf to run a batch file that will have a win32/winform GUI windows interface to allow the user to select a program to run from the beginning similiar to like this: Please let me know if windows allows this without it being done programmatically. I know their are some automation programs that work by generating code based on what it records you do. But I don't knwo of any already built windows prompt like this, so I don't knwo how to record such an action.

• Correct For Loop Design

  - by Yttrill

  What is the correct design for a for loop? Felix currently uses if len a > 0 do for var i in 0 upto len a - 1 do println a.[i]; done done which is inclusive of the upper bound. This is necessary to support the full range of values of a typical integer type. However the for loop shown does not support zero length arrays, hence the special test, nor will the subtraction of 1 work convincingly if the length of the array is equal to the number of integers. (I say convincingly because it may be that 0 - 1 = maxval: this is true in C for unsigned int, but are you sure it is true for unsigned char without thinking carefully about integral promotions?) The actual implementation of the for loop by my compiler does correctly handle 0 but this requires two tests to implement the loop: continue: if not (i <= bound) goto break body if i == bound goto break ++i goto continue break: Throw in the hand coded zero check in the array example and three tests are needed. If the loop were exclusive it would handle zero properly, avoiding the special test, but there'd be no way to express the upper bound of an array with maximum size. Note the C way of doing this: for(i=0; predicate(i); increment(i)) has the same problem. The predicate is tested after the increment, but the terminating increment is not universally valid! There is a general argument that a simple exclusive loop is enough: promote the index to a large type to prevent overflow, and assume no one will ever loop to the maximum value of this type.. but I'm not entirely convinced: if you promoted to C's size_t and looped from the second largest value to the largest you'd get an infinite loop!

• Recommended requirements when outsourcing xhtml/css site building?

  - by András Szepesházi

  I'm considering outsourcing a part of our web application development project for freelancers, namely the site building part. What I mean by site building is the process of creating the xhtml/css template files, with dummy content, from a psd file (or any other graphical layout file). The resulting xhtml/css files will be used by our developers as templates for cms based page rendering. The cms in this case is Drupal, but that might not be of much relevance. I'm looking for a good set of requirements, that will result in good quality xhtml/css code, complying with today's standards leaves little to the freelancer developer's imagination in terms of what I need I'm thinking about requirements like: Valid XHTML 1.0 Transitional document type, validated by validator.w3.org Identical rendering in all modern browsers (FF, Chrome, Safari, Opera, IE7-8) and also in IE6 All opening and closing block-level elements should be properly commented, referencing the functional part of the user interface they belong to (menu, toolbar, content, etc) No inline CSS definitions And so on. How would you organize a list like that? What requirements would you add?

• How do you safely comment out code in Visual Studio and TFS?

  - by burnt1ce

  Once in a while, a co-worker check-ins bad code and this blocks you from your application from initializing properly so you can continue doing your work. To get around this problem quickly, I've commented out the offending code. I accidentally to uncomment out the offending code at the time of check-in and I want to prevent this from happening again. Do you have a trick to 1) disable bad code that stop you from working 2) prevent yourself from checking in unwanted changes? I'm currently using Visual Studio as my IDE and TFS as my source code repo.

• What problems will I face if I remove the concept of interfaces from my code?

  - by Vishwas Gagrani

  I have been programming for many years but I am still not comfortable with the concept of "Interfaces". I try to use interfaces but many times I don't see a mandatory use for it. I think this is probably because the projects weren't so big, or because interfaces are more useful when teamwork is involved. So, making another attempt to understand the importance of interfaces, here is my question: What problems will I face if I remove the concept of interfaces from my code?

• Thoughts of Cloud Development/Google App Engine

  - by jiewmeng

  I use mainly PHP for web development, but recently, I started thinking about using Google App Engine. It doesn't use PHP which I am already familiar with, so there will be a steeper learning curve. Probably using Python/Django. But I think it maybe worthwhile. Some advantages I see: Focus on App/Development. No need to setup/maintain server ... no more server configs Scales automatically Pay for what you use. Free for low usage Reliable, it's Google after all Some concerns though: Does database with no joins pose a problem for those who used App Engine before? Do I have to upload to Google just to test? Will it be slow compared to testing locally? What are your thoughts and opinions? Why would you use or not use App Engine?

• Tips or techniques to use when you do't know how to code something?

  - by janoChen

  I have a background as UI designer. And I realized that it is a bit hard for me to write a pieces of logic. Sometimes I get it right, but most of the time, I end up with something hacky (and it usually takes a lot of time). And is not that I don't like programming, in fact, I'm starting to like it as much as design. It's just that sometimes I think that I'm better at dealing with colors an shapes, rather than numbers and logic (but I want to change that). What I usually do is to search the solution on the Internet, copy the example, and insert it into my app (I know this is not a very good practice). I've heard that one tip was to write the logic in common English as comment before writing the actual code. What other tips and techniques I can use?

• Web Developer or Software Engineer?

  - by dahacker89

  A question that I have been asking myself and really confused which path to take. So I need your guys help as to the pros and cons of these 2 professions in today's world. I love web applications development as the Web is the best thing to happen in this age and nearly everyone gets by on the World Wide Web. And also tend to keep learning about new technologies and about web services. On the other hand I like software engineering also for the desktop applications as I have had experience with development small scale softwares in VB.Net, Java, C++, etc. Which path has more scope and better future? Whats your view?

• Intellectual Property for in house development

  - by Kyle Rogers

  My company is a sub contractor on a major government contract. Over the past 5 years we've been developing in house applications to help support our company and streamline our work. Apparently in 2008 our president of the company at that time signed a continuation of services contract with the company we subcontract with on this project. In the contract amendment various things were discussed such as intellectual property and the creation of new and existing tools. The contract states that all the subcontractor's tools/scripts/etc... become the intellectual property of the main contractor holder. Basically all tools that were created in support of the project which we work on are no longer ours exclusively and they have rights to them. My company really doesn't do software development specifically but because of this contract these tools helped tremendously with our daily tasking. Does my company have any sort of recourse or actions to help keep our tools? My team of developers were completely unaware of any of these negotiations and until recently were kept in the dark about the agreements that were made. Do we as developers have any rights to the software? Since our company is not a software development shop, we have created all these tools without any sort of agreements or contracts within the company stating that we give our company full rights to our creations? I was reading an article by Joel Spolsky on this topic and was just wonder if there is any advice out there to help assist us? Thank you Joel Spolsky's Article

• Design Code Outside of an IDE (C#)?

  - by ryanzec

  Does anyone design code outside of an IDE? I think that code design is great and all but the only place I find myself actually design code (besides in my head) is in the IDE itself. I generally think about it a little before hand but when I go to type it out, it is always in the IDE; no UML or anything like that. Now I think having UML of your code is really good because you are able to see a lot more of the code on one screen however the issue I have is that once I type it in UML, I then have to type the actual code and that is just a big duplicate for me. For those who work with C# and design code outside of Visual Studio (or at least outside Visual Studio's text editor), what tools do you use? Do those tools allow you to convert your design to actual skeleton code? It is also possible to convert code to the design (when you update the code and need an updated UML diagram or whatnot)?
