• New insights I can learn from the Groovy language

  - by Andrea

  I realize that, for a programmer coming from the Java world, Groovy contains a lot of new ideas and cool tricks. My situation is different, as I am learning Groovy coming from a dynamic background, mainly Python and Javascript. When learning a new language, I find that it helps me if I know beforehand which features are more or less old acquaintances under a new syntax and which ones are really new, so that I can concentrate on the latter. So I would like to know which traits distinguish Groovy among the dynamic languages. What are the ideas and insights that a programmer well-versed in dynamic languages should pay attention to when learning Groovy?

• Is it possible to get a job in a high-demand company without having hobby projects?

  - by Rachel

  I was curious if the recruitment team at high-demand companies such as Google takes a lack of hobby projects into consideration when evaluating candidates. I'm a straight 40 hour/week programmer, who is lucky to spend an hour or two a month outside of work on anything programming related. I love hanging out on SO/SE during my breaks at work, and love answering questions, but after work I leave the programming world and go back to my life. I already understand that you don't need hobby projects to be a good programmer, but does this lack of hobby projects affect my chances getting a job at a company that always has a long list of candidates trying to get in?

• Good book for improving c# skills?

  - by JMarsch

  Hello: I was asked to recommend a good book for a mid-level experienced developer who wants to improve their coding skills (c# developer). I was thinking about: Code Complete: http://www.amazon.com/Code-Complete-Practical-Handbook-Construction/dp/0735619670/ref=sr_1_1?ie=UTF8&qid=1291221928&sr=8-1 The Pragmatic Programmer: http://www.amazon.com/Pragmatic-Programmer-Journeyman-Master/dp/020161622X/ref=sr_1_3?ie=UTF8&qid=1291221928&sr=8-3 or Effective C#: http://www.amazon.com/Effective-Covers-4-0-Specific-Development/dp/0321658701/ref=sr_1_1?s=books&ie=UTF8&qid=1291222038&sr=1-1 What do you think about those? Any other suggestions?

• Steps to create a solution for a problem

  - by Mr_Green

  I am a trainee. According to my teacher, he says that to solve a problem we should go with steps to solve it like Create Algorithm (optional) Create a Datatable: By analyzing the problem, create main concepts in those problem as columns and the related issues in the main concept as rows. Create a Flowchart based on the Datatable. (when creating flow chart, think that you are in that situation and design it in your brain) By seeing the Flowchart, solve the problem. These steps should always consider by a programmer if he/she wants to become a Software designer (not programmer). Because the above approach gives an efficient way of finding solution to a problem even the problem is small. According to him, this way of approach also works in real time scenario's. My question is: Is this really an efficient way? please share also your thoughts. Keeping beside my question I just want to share some thoughts of my teacher with you who is a good mentor for me.

• Is Java much harder to "tweak" for performance compared with C/C++?

  - by user997112

  Does the "magic" of the JVM hinder the influence a programmer has over micro-optimisations in Java? I recently read in C++ sometimes the ordering of the data members can provide optimizations (granted, in the microsecond environment) and I presumed a programmer's hands are tied when it comes to squeezing performance from Java? I appreciate a decent algorithm provides greater speed-gains, but once you have the correct algorithm is Java harder to tweak due to the JVM control? If not, could people give examples of what tricks you can use in Java (besides simple compiler flags).

• Is there a recommended order to take the Oracle Java EE certification exams?

  - by Karl

  I recently passed the Oracle Certified Professional, Java SE 6 Programmer examination. Now, my boss would like me to take "the next step" to broaden my competence. I tried to explain that there is no equivalent Java EE 6 Programmer examination, but a number of different exams, such as Web Services, Web Components, and Enterprise JavaBeans. Is there a recommended path to follow for the various Oracle certifications in the Enterprise Edition of Java? Is it logical to take some exams prior to taking others because the content builds upon previous knowledge or are they all independent?

• Creating a portfolio of projects [closed]

  - by Ryan

  As I pursue the path of becoming a programmer, I would like to build up a portfolio of projects I worked on at my current job so that I can eventually get programming work elsewhere (either as an employee, contractor, one man consulting shop, etc). Some of these were things I coded myself, others I was instrumental in the architecture, design and functionality (ie, not as a programmer but more of a BA). How do I show the work that I have done to others on the projects that I have produced for the company I work at? This is all internal software, so it's not something that the outside world would be able to use, and some of our products contain proprietary financial market tools and it would not be prudent to share those with the outside world. My guess is that screenshots would definitely be out of the question, as well as functional descriptions of the software.

• Why does everyone dislike PHP? [closed]

  - by SomeKittens

  I'm primarily a Java/Python programmer, but I just picked up an entry-level job doing web development. I had to learn PHP, and several of my CS friends told me that it would stunt my coding ability/be terrible to program in/murder me in the middle of the night. So far, there have been annoying moments with the language (one particular thing that bugs me is the syntax for calling functions...), but nothing living up to the statements of my friends. I still haven't learned very much about the language. Is their hate justified? Why or why not? A few quotes I've seen about PHP: Haskell is faster than C++, more concise than Perl, more regular than Python, more flexible than Ruby, more typeful than C#, more robust than Java, and has absolutely nothing in common with PHP. Audrey Tang "PHP is a minor evil perpetrated and created by incompetent amateurs, whereas Perl is a great and insidious evil, perpetrated by skilled but perverted professionals." Jon Ribbens.

• Is age a factor when looking for internships? [closed]

  - by user786362

  Possible Duplicate: Is it ever too old to learn how to become a programmer? I'm 30 years old going back to school for a 2nd degree in Computer Science. I will be transferring to my local state university this fall and would like to know if my age will be a factor when applying for internships. I have already read a few threads about age and careers: Is it too late to start your career as a programmer at the age of 30? Does it matter that you started developing at 26? While it is reassuring to know that people are getting entry-level programming jobs at 30+, what about internships? Should I even bother with bigger companies like Google, Microsoft, or Apple? I know we have laws against age-discrimination but lets not pretend we live in a perfect world where everyone follows the rules.

• Programming C++ using Qt4

  - by DaGhostman Dimitrov

  Hey guys I am really new to the C++ programing I have a little knowledge in C and a bit more in C++, but I do not know them enough to call myself a programmer. I am working as a PHP Web Developer I like being a crafts man and creating things so that is the reason to combine the programming with web development. I think that I could really benefit from both of them and so... My question is: Is it a good Idea to learn C++ with Qt or not? Can you give me pros and cons of both? Note: I do not want to become a programmer and give up the web development I want to combine them both.

• Does a person's day-to-day neatness (outside of programming) relate to quality and organization in programming?

  - by jiceo

  Before anyone jumps into any conclusion, I had a discussion with a friend (who's not a programmer at all) about the relationship between a person's neatness habit and the degree of neatness generally shown in works by the same person. This led me to think about this situation: Let's imagine you knew a programmer whose house was very messy. This person's lifestyle is messy by nature. On his desk there are books, papers, STUFF, piled everywhere including on the floor, mixed with dirty clothing, with no obvious organization at all. If you asked him to find a book he hasn't touched for at least a week from the cluster of chaos, he would take at least an hour to do so. How likely is it that he will produce very clean, consistent, and organized code that other people can use? Are there CS legends that are/were notoriously messy in day-to-day habits?

• Advice on what to learn? [closed]

  - by ICTech

  Currently I work as a .NET C# programmer, quite fresh faced at that (only been working professionally for 8 months) I'm enjoying what I'm doing, but I'm now thinking ahead for other languages to learn. I've heard from quite a few seasoned developers that they reckon it's worth getting in to HTML5. Before I asked this question I read a few of the other questions similar to this, but most were dated back a few years. I'm wondering what your advice would be to an aspiring programmer, what I should avoid going for (i.e. as I understand it Flash is essentially going to be phased out due to HTML5) I was looking in to WPF and the more updated .NET technologies, but someone advised me that WPF stuff will probably be redundant in the future. Thanks for your advice and opinions :)

• Are there any Phone Interview equivalents to FizzBuzz?

  - by Jordan

  I think FizzBuzz is a fine question to ask in an in-person interview with a whiteboard or pen and paper handy to determine whether or not a particular candidate is of bare-minimum competence. However, it does not work as well on phone interviews because any typing you hear could just as easily be the candidate's Googling for the answer (not to mention the fact that reading code over the phone is less than savory). Are there any phone-interview questions that are equivalent to FizzBuzz in the sense that an incompetent programmer will not be able to answer it correctly and a programmer of at least minimal competence will? Given a choice, in my particular case I am curious about .NET-centric solutions, but since I was not able to find a duplicate to this question based on a cursory search, I would not mind at all if this question became the canonical source for platform-agnostic phone fizzbuzz questions.

• Is it a good idea to always use Google as the first step to solving a problem? [closed]

  - by The Rubber Duck

  Possible Duplicate: Importance of learning to google efficiently for a programmer? Avoiding lengthy discussions, as a senior level student in CS, how can I get away from Googling problems I run into? I find myself using it too much; I seemingly reach for the instant answer and then blindly copy and paste code, hoping it works. Anyone can do that. I've read the related threads about being a better programmer, but mostly those recommend practicing on pet projects, which I have done, but again I feel EVERY wall encountered, from design through completion, was hurdled with Google. Do professionals instantly "research" their problem? Or do you guys step back and try and figure it out yourselves? I'm talking about both 'algorithm/design' problems as well as compiler issues.

• Why can't Java/C# implement RAII?

  - by mike30

  Question: Why can't Java/C# implement RAII? Clarification: I am aware the garbage collector is not deterministic. So with the current language features it is not possible for an object's Dispose() method to be called automatically on scope exit. But could such a deterministic feature be added? My understanding: I feel an implementation of RAII must satisfy two requirements: 1. The lifetime of a resource must be bound to a scope. 2. Implicit. The freeing of the resource must happen without an explicit statement by the programmer. Analogous to a garbage collector freeing memory without an explicit statement. The "implicitness" only needs to occur at point of use of the class. The class library creator must of course explicitly implement a destructor or Dispose() method. Java/C# satisfy point 1. In C# a resource implementing IDisposable can be bound to a "using" scope: void test() { using(Resource r = new Resource()) { r.foo(); }//resource released on scope exit } This does not satisfy point 2. The programmer must explicitly tie the object to a special "using" scope. Programmers can (and do) forget to explicitly tie the resource to a scope, creating a leak. In fact the "using" blocks are converted to try-finally-dispose() code by the compiler. It has the same explicit nature of the try-finally-dispose() pattern. Without an implicit release, the hook to a scope is syntactic sugar. void test() { //Programmer forgot (or was not aware of the need) to explicitly //bind Resource to a scope. Resource r = new Resource(); r.foo(); }//resource leaked!!! I think it is worth creating a language feature in Java/C# allowing special objects that are hooked to the stack via a smart-pointer. The feature would allow you to flag a class as scope-bound, so that it always is created with a hook to the stack. There could be a options for different for different types of smart pointers. class Resource - ScopeBound { /* class details */ void Dispose() { //free resource } } void test() { //class Resource was flagged as ScopeBound so the tie to the stack is implicit. Resource r = new Resource(); //r is a smart-pointer r.foo(); }//resource released on scope exit. I think implicitness is "worth it". Just as the implicitness of garbage collection is "worth it". Explicit using blocks are refreshing on the eyes, but offer no semantic advantage over try-finally-dispose(). Is it impractical to implement such a feature into the Java/C# languages? Could it be introduced without breaking old code?

• When to Use workflow engines?

  - by A01_

  I'm totally new to this concept from design perspective. I've worked in past on some of the workflow engines as programmer but never had a clarity on why we chose the work-flow engines in first place. And as programmer I know that there are at least 100 ways to do anything when you are writing code but only few of the ways are the best! I still don't understand which use cases are best solved by workflow engines (or rather their concept) than designing a good DI enabled application. I'm looking for any general characteristics of domain-neutral use cases, where work-flow engines are one of the the best options. So my question is: What are general characteristics of a requirement which can be taken as a signal for opting for a good workflow engine and coding around it? Cheers!

• Programming Carreer. What should i choose? [closed]

  - by thenewbie

  I have an experience in programming. Im not that experience but i have created some desktop application like payroll etc. In web i had created some websites. Now im studying java for android. I already created an application on android and submitted it on google play.However, i feel like the excitement in creating application for android or web is gone. What i think i like is to program in c++ language. but i have a doubt mastering it. Because nowadays only a handful of company hire a c++ junior programmer. I think only in gaming industry that they would hire a c++ programmer and has an 3 or more years of xp. While in java there are lots of oppurtuniy especialy for android. and I dont have a plan studying objective c cause i dont have mac. SO what should i realy choose? thank you..

• My Future as a Developer

  - by jmquigley

  You have been a developer for 16 years, mostly in the unix environment woring with C, C++ and Java. You are proficient in those skills, but can always improve. The jobs for C and C++ developers working in the Unix environment are not as plentiful as they used to be, so you're looking to expand your skills. If you were going to focus on an area of technology for the next 10 years, and you had a choice of C# or to continue with your work in Java and expand those skills, which would you choose and why? I love being a programmer. I want to focus on an area that would put me in demand so that I can continue to be a programmer. This is not meant to be subjective, I'm looking for guidance and advice from other professionals. This is a question that is at the front of my mind right now. TIA.

• Where do all the old programmers go?

  - by Tony Lambert

  I know some people move over to management and some die... but where do the rest go and why? One reason people change to management is that in some companies the "Programmer" career path is very short - you can get to be a senior programmer within a few years. Leaving no way to get more money but to become a manager. In other companies project managers and programmers are parallel career paths so your project manager can be your junior. Tony

• Really "wow" them in the interview

  - by Juliet

  Let me put it to you this way: I'm a top-notch programmer, but a notoriously bad interviewee. I've flunked 3 interviews consecutively because I get so nervous that my voice tightens at least 2 octaves higher and I start visibly shaking -- mind you, I can handle whatever technical questions the interviewer throws at me in that state, but I think it looks bad to come off as a quivering, squeaky-voiced young woman during a job interview. I've just got the personality type of a shy computer programmer. No matter how technical I am, I'm going to get passed up in favor of a smooth talker. I have another interview coming up shortly, and I want to really impress the company. Here are my trouble spots: What can I do to be less nervous during my interview? I always get really excited when I hear I have a face-to-face interview, but get more and more anxious as D-Day the interview approaches. My employers wants me to explain what I used to do at my prior employment. I'm a very chatty person and tend to talk/squeak for 10 minutes at a time. How long or short should I time my answers? On that note, when I'm explaining what I did at prior jobs, what exactly is my interviewer looking for? At some point, my interviewer will ask "do you have any questions for me while you're here?" I should, but what kinds of questions should I ask to show that I'm interested in being employed? My interviewer always asks why I'm looking for a new job. The real reason is that my present salary is $27K/yr [Edit to add: and I've yet to get a raise since I started], and I want to make more money -- otherwise the work environment is fine. How do I sugarcoat "I want to make more money" into something that sounds nicer? I have only one prior programmer job, and I've worked there for 18 months, but I have the skill of someone with 4 to 6 years of experience. What can I say to compete against applicants with more work experience? I took a low-paying $27K/yr programming job just to get my foot in IT, and I've been trying to leverage that job as a stepping stone to better opportunities. I get interviews because I consistently out-score senior-level developers in aptitude tests, and my desired salary range is right in the ballpark of what most companies want to offer. Unfortunately, while I've been a programming as a hobby for 10 years and I'm geared to graduate with my BA in Comp Sci in May '09, employers see me as a junior-level programmer with no degree. I want to prove them wrong and get a job that matches my skill level. I'd appreciate any advice anyone has to offer, especially if they can help me get a better job in the process.
