• Does an inexperienced programmer need an IDE?

  - by Torben Gundtofte-Bruun

  Reading this other question makes me wonder if I (as an absolute beginner PHP programmer) should stick with WAMP and Notepad++ or to switch to some IDE like Eclipse. It's understandable that skilled developers will benefit from a big shiny IDE. But why should an absolute beginner use an IDE? Do the benefits outweigh the extra challenge of learning the IDE on top of learning to develop? Update for clarification: My goal is to get some basic programming experience. By choosing PHP and WAMP (and FogBugz and Kiln) I hope to avoid having to navigate the tricky / messy OS specifics and compiling etc. and just focus on basic functionality like an online user registration form. I've got lots of theoretical understanding from university a decade ago but no practical experience. I want to remedy that with a hobby project that would be similar to a real-world sellable web app. There are so many questions to ask. So many pitfalls I probably have to blunder into. This question is just one piece (my first!) of that puzzle.

• Learning OO for a C Programmer

  - by Holysmoke

  I've been programming professionally in C, and only C, for around 10 years in a variety of roles. As would be normal to expect, I understand the idioms of the language fairly well and beyond that also some of the design nuances - which APIs to make public, who calls what, who does what, what is supposed to reentrant and so on. I grew up reading 'Writing Solid Code', it's early C edition, not the one based on C++. However, I've never ever programmed in an OO language. Now, I want to migrate to writing applications for iPhone (maybe android), so want to learn to use Objective-C and use it with a degree of competence fitting a professional programmer. How do I wrap my head around the OO stuff? What would be your smallest reading list suggestion to me. Is there a book that carries some sort of relatively real world example OO design Objective-C? Besides, the reading what source code would you recommend me to go through. How to learn OO paradigm using Objective-C?

• How to tackle an experienced C# Programmer?

  - by nandu.com

  I am a noob in c# and asp.net developing. I have spent 6 months in design and another 6 in sql and asp.net programming. I just know the basics of asp.net and C#. I was programming as per the instruction of my tech leads and all good things changed in a day. :( All my tech leads (2+ experienced) left the company complaining about salary. And instead of those, company has recruited a 5+ experienced programmer cum tech lead (who is very strict), he is expecting me to code anything he says. Previous seniors of me, would say 'use ajax for this, use query for this instead of coding' and so on. I will do it exactly. I am not experienced enough to perform it myself. Now I am in a dilemma. I want to stay in the company and learn some more, but this new tech lead is expecting me to learn everything myself (he is telling me to learn jquery, javascript menus, session and chart in .Net, and so on and do things myself without asking him anything...I mean anything) :(((( PLease suggest to me some good tips to handle him. I think all programmers world wide would have faced a similar problem atleast once in the big programming life. So please..help .. 911

• How does a single programmer make a game?

  - by Mike

  I have always been a software developer, but lately I've been wanting to get into games. The only thing stopping me is the fact that I'm a programmer, not an artist. I've made some simple stuff, Tetris, 2D chess things like that but I can't do much art and that's really what holds me back. Now the problem is, I've yet to go to college so most commercial projects wouldn't accept me even to work for free and learn a bit especially with my lack of experience in games and any indie projects I've looked into really have an issue with responding to people interested, or actually completing (or starting really, most don't get past the ideas on paper) the project they want to do. I've looked around locally for artists, anyone who can do modeling, textures or animating or even anyone with some ability to make some more advanced 2D assets to get something like a side-scrolling RPG or something but haven't been able to find anyone. So how do you guys do it? Do I really just have to wait until I can go to college to see if I like working with games or is there some way I can get art (for free, anything I do is just going to be for fun so I don't want to have to sink money into it) and just start messing around on my own? Or am I just having bad luck and not looking in the right places for other people interested in having me help? I'm not looking for anything in particular, just something to fill some time with and see if I like making games. If not, well I'll go back to my software projects. I just have one more year of highschool and I'd like to try a few different areas before I go to college.

• Shoring up deficiencies in a "home grown" programmer?

  - by JohnP

  I started out by teaching myself BASIC on a Vic 20, and in college (mid 80's) I had Fortran, Pascal, limited C, machine and assembler (With a smattering of COBOL). I didn't touch programming from approx 1989 to 1999. At that point, I was lucky enough to get hired as a Clipper programmer. Took me about 6 months to learn most of it, and by now (13 yrs) I'm pretty expert in it. I have also picked up Cold Fusion, some C#, some ASP, SQL, etc. I know programming structures, but in most languages I'm missing the esoterics, and I know my code could be much tighter. The problem is that I've learned what I needed to, to get the job done. This results in a lot of gaps in practical knowledge. I am also missing out on a TON of theory. Things like SRP, Refactoring, etc are alien terms. (Although I grok the intent after a short read). In addition, I am in the position now of teaching junior programmers the company and our software, and I don't want to pass on the knowledge gaps. I know this is somewhat of a subjective question and may be closed, but how do you go back and pick up what you've missed?

• Need Directions to become a programmer [closed]

  - by Omin

  Before youguys go on about how there are many types of programmers, please read through the post. Long term goal: Develop my own software (company) Short term goal: Get a job that involves coding/programming Current status: Support Analyst (at a software company but does not involve any programming) with 40k salary, 3rd year computer engineering student I had everything figured out. I'm going to develop a 2D scrolling game for iphone or android, publish the app, sell a bunch, and then apply at a studios as a software developer. And then something hit me. I think I need to get a job that involes programming to learn as much as I can in the shortest time possible. So I got a phone interview at a fast growing start up software company, passed that no problem, but then had to take an online technical assessment. That failed miserably. I thought that if I could just present myself, show that I am hard working, positive attitude, eager to make self improvements, type of a guy, I could get the job. I was wrong. And now, I am lost. Im thinking of staying with my job until I find a new one as a programmer. I will be working, self studying, and trying to make this happen without finishing university. I forgot to mention that the online technical assessment was based on data structures/algorithms, OO design, runtime complexity. I was hoping that I could get some guidence. Should I be focusing on app development or study computer science fundamentals? I have a list of books I can be going through: Learning C# O'Reilly (I got interested in C# because of Unity3D and Mono), C# 5.0 in a Nutshell, Head First Design Patterns, Code Complete, Introduction to Algorithms, Programming Interviews Exposed, Cracking the Coding Interview, The Google Resume.

• How to move from Programmer to Project Lead

  - by DoctaStooge

  At my job, I'm currently a programmer, but in the next few weeks I'll be taking control my own project. I was wondering if anyone else here has been in the same situation, and if so, what advice you can offer to help me be able to better run my project. Experience in dealing with contractors would be greatly appreciated. A little more info: Project will have 3 people including myself, with extra people coming in when needing testing. The project has been programmed mainly by 2 people I would like to contribute to the programming as I like doing it and think I can add to the program, but am afraid of how the contractors will react. I don't want to create bad feelings which may harm the project. EDIT: Forgot to mention that I'll have to be picking up communications with customers to make sure their needs are met. Any advice on talking to customers cold would be greatly appreciated. EDIT 2: This is not a new project, I'm picking it up around version 6. Sorry that I didn't make it clear before.

• Oracle SQL Developer: Single Object Compare

  - by thatjeffsmith

  There’s a nasty rumor going around that you can’t compare database objects and/or code in Oracle SQL Developer. So let’s put that to bed right now. First, here’s how to compare: PL/SQL to PL/SQL or a SQL statement to another SQL statement So now that that’s settled, why don’t we take a look at how to compare a single table, to another table – whether it’s in the same database or a different database. Database Diff There’s no additional licensing requirement here. If you have SQL Developer, you can use this feature. if you’re going to compare 1 table to another, make sure you ONLY have ‘tables’ checked And then, use this dialog to select your table(s): Move over the object(s) you want to compare over to the right hand side. And now we can move onto the results. The differences, side-by-side, and the script to make B look like A Common lines with differences are highlighted in blue, new lines are highlighted in red. So that’s why they are different, but here’s the script to synch up the differences: Read the script, TEST the script, apply the script. And that’s it. Well, that’s mostly it. If you have questions about how to compare a database object in a schema you don’t have the login information for, read this post next.

• ASP.NET MVC 4: Short syntax for script and style bundling

  - by DigiMortal

  ASP.NET MVC 4 introduces new methods for style and scripts bundling. I found something brilliant there I want to introduce you. In this posting I will show you how easy it is to include whole folder with stylesheets or JavaScripts to your page. I’m using ASP.NET MVC 4 Internet Site template for this example. When we open layout pages located in shared views folder we can see something like this in layout file header: <link href="@System.Web.Optimization.BundleTable.Bundles.ResolveBundleUrl("~/Content/css")" rel="stylesheet" type="text/css" />    <link href="@System.Web.Optimization.BundleTable.Bundles.ResolveBundleUrl("~/Content/themes/base/css")" rel="stylesheet" type="text/css" />    <script src="@System.Web.Optimization.BundleTable.Bundles.ResolveBundleUrl("~/Scripts/js")"></script> Let’s take the last line and modify it so it looks like this: <script src="/Scripts/js"></script> After saving the layout page let’s run browser and see what is coming in over network. As you can see the request to folder ended up with result code 200 which means that request was successful. 327.2KB was received and it is not mark-up size for error page or directory index. Here is the body of response: I scrolled down to point where one script ends and another one starts when I made the screenshot above. All scripts delivered with ASP.NET MVC project templates start with this green note. So now we can be sure that the request to scripts folder ended up with bundled script and not with something else. Conclusion Script and styles bundling uses currently by default long syntax where bundling is done through Bundling class. We can still avoid those long lines and use extremely short syntax for script and styles bundling – we just write usual script or link tag and give folder URL as source. ASP.NET MVC 4 is smart enough to combine styles or scripts when request like this comes in.

• Managing Scripts in Oracle SQL Developer

  - by thatjeffsmith

  You backup your databases, right? You backup you home computer – your media collection, tax documents, bank accounts, etc, right? You backup your handy-dandy SQL scripts, right? Ok, now that I’ve got your head nodding, I want to answer a question I get every so often: How can I manage my scripts in SQL Developer? This is an interesting question. First, it assumes that one SHOULD manage their scripts in their IDE. Now, what I think the question generally gets around to is, how can we: Navigate to our scripts Open them Execute them What a good IDE should have is an interface to your existing Version Control System (VCS.) SQL Developer supports out-of-the-box both Subversion and Git. You can also download an extension via check-for-updates to get support for CVS. Now, what I’m about to show you COULD be done without versioning and controlling your scripts – but I want to ask you why you wouldn’t want to do this? So, I’m going to proceed and assume that you do INDEED version your scripts already. Seeing what scripts you’ve already got in your repository This is very straightforward – just open the Team Versions panel. Then connect to your repository. Shows you the files in your source control system. Now, I could ‘preview’ said file right away. If I open the file from here, we get a temp file copy down from the server to the local machine. This is a local temp copy of the controlled script – I can read/execute, but not write to it. And that might be all you need. But, if your script calls other scripts, then you’re going to want to check out the server copy of your stuff down your local SVN working copy directory. That way when your script calls another script – you’re executing the PRODUCTION APPROVED copies of said scripts. And if you do SPOOL or other file I/O stuff, it will work as expected. To get to those said client copies of your scripts… Enter the Files Panel The Files panel is accessible from the View menu. You can get to your files, one of two ways. If you’ve touched the file recently, you can see it under the Recent tree. Otherwise, you can navigate to your local ‘checked out’ copies of your script(s). Open your local copies, see what’s changed, etc. And I can access the change history and see what’s been touched… What changes am I going to ‘push out’ if I commit this back to the server? Most of us work on teams, yes? This panel also gives me a heads up if someone else is making changes to the same file. I can see the ‘incoming’ changes as well. To Sum It Up… If I want to get a script to run: do a full get to your local directory open the script(s) The files panel will tell you if your local copy is out of date from the server and if you have made local changes you’ve forgotten to commit back up to the server and your fellow teammates. Now, if you’re the selfish type and don’t want to share, that’s fine. But you should still be backing up your scripts, and you can still use the Files panel to manage your scripts.

• Why is this by passing the SUDO password?

  - by John Isaacks

  I have a bash script I am using to automate a SVN checkout. The contents of the file were: #!/bin/bash cd /var/www-cake sudo svn checkout file:///usr/local/svn/bash_repo/repo/ Then when I double click the file it would ask me what to do, I would click the button "Run In Terminal" and then a terminal would pop up and ask me for the SUDO password. I would enter it, the script would execute and the terminal would close. I wanted to give some sort of indication that the script ran successfully so I edited my file to look like: #!/bin/bash cd /var/www-cake sudo svn checkout file:///usr/local/svn/bash_repo/repo/ echo "Head revision has been pushed to live server" I expected the terminal to now stay open and tell me the message afterwards. To my surprise it now opens and immediately closes. The script does execute and I no longer have to put in the SUDO password. Is this right? I do not understand why this is happening, seems like a security issue.

• script engine with no global environment (java)

  - by user1886930

  I am curious about how global variables are handled by script engines. I am looking for a script engine that does not preserve the state of global variables upon invocation. Are there such engines out there? We are looking for a scripting language we can use under the script engine API for Java. When making multiple invocations of a script engine, top-level calls to eval() or evaluate() method preserves the state of global variables, meaning that consequent calls to eval() will use the global variables as they were left by the last invocation. Is there a script engine that does not preserve the state, or provides the ability to reset the state, so that global variables are at their initial state every time the script engine is invoked?

• Get AutoHotkey Script To Run As Admin At Startup

  - by deadlydog

  A few weeks back I posted some problems with running AutoHotkey (AHK) in Windows 8, and that the solution was to run your AHK script as admin.  I also showed how to have the script start automatically when you logged into Windows.  What I didn’t realize at the time though was that the method only worked because I had disabled UAC in the registry (which prevents most Metro apps from working in Windows 8, and likely isn’t acceptable for most people). So here is a Windows 8, UAC-friendly method to accomplish the same task (also works in previous versions of Windows).  The trick is to use the Task Scheduler: 1. Open the Task Scheduler (also known as “Schedule tasks” in Windows 8 Settings).   2. Create a new Basic Task. 3. Give it a name and description (something like “launch AutoHotkey script at login”), and then specify to have it run “When I log on”.  Then specify that you want it to “Start a program”, and then point it towards your AutoHotkey script.  Before you finish the wizard, check off “Open the Properties dialog for this task when I click Finish”.   4. When that Properties dialog opens up, go to the Conditions tab and make sure none of the checkboxes under the Power category are checked off; this will ensure the script still launches if you are on a laptop and not plugged into AC power.   5. Now here is the important part; To have your script “Run as admin”, on the General tab check off “Run with highest privileges”. Now your AHK script should start automatically as soon as you log into Windows; even when UAC is enabled   6. If your AHK script uses an #Include statement to include other files, you may get an error similar to this one when your task runs: “#Include file … cannot be opened. The program will exit.” The solution to this is to tell your AHK script to start in the same directory as the file that you want to include.  So you will need to edit your scheduled task’s Action to specify the Start In directory. Happy coding!

• How do I write find/write the script to restore a guest user in Lion (Mac OS X)?

  - by Avry

  In Mac OS X 10.7, you cannot have a guest user if you encrypt the entire drive. An alternative is to create a psuedo-guest user. One of the downsides is that the feature where the guest user is restored to original state no longer exists. How do I write a script that restores the User Template found in /System/Library/User Template/English.lproj? I would also have to figure how to activate this script either at login or on logout.

• Surviving MATLAB and R as a Hardcore Programmer

  - by dsimcha

  I love programming in languages that seem geared towards hardcore programmers. (My favorites are Python and D.) MATLAB is geared towards engineers and R is geared towards statisticians, and it seems like these languages were designed by people who aren't hardcore programmers and don't think like hardcore programmers. I always find them somewhat awkward to use, and to some extent I can't put my finger on why. Here are some issues I have managed to identify: (Both): The extreme emphasis on vectors and matrices to the extent that there are no true primitives. (Both): The difficulty of basic string manipulation. (Both): Lack of or awkwardness in support for basic data structures like hash tables and "real", i.e. type-parametric and nestable, arrays. (Both): They're really, really slow even by interpreted language standards, unless you bend over backwards to vectorize your code. (Both): They seem to not be designed to interact with the outside world. For example, both are fairly bulky programs that take a while to launch and seem to not be designed to make simple text filter programs easy to write. Furthermore, the lack of good string processing makes file I/O in anything but very standard forms near impossible. (Both): Object orientation seems to have a very bolted-on feel. Yes, you can do it, but it doesn't feel much more idiomatic than OO in C. (Both): No obvious, simple way to get a reference type. No pointers or class references. For example, I have no idea how you roll your own linked list in either of these languages. (MATLAB): You can't put multiple top level functions in a single file, encouraging very long functions and cut-and-paste coding. (MATLAB): Integers apparently don't exist as a first class type. (R): The basic builtin data structures seem way too high level and poorly documented, and never seem to do quite what I expect given my experience with similar but lower level data structures. (R): The documentation is spread all over the place and virtually impossible to browse or search. Even D, which is often knocked for bad documentation and is still fairly alpha-ish, is substantially better as far as I can tell. (R): At least as far as I'm aware, there's no good IDE for it. Again, even D, a fairly alpha-ish language with a small community, does better. In general, I also feel like MATLAB and R could be easily replaced by plain old libraries in more general-purpose langauges, if sufficiently comprehensive libraries existed. This is especially true in newer general purpose languages that include lots of features for library writers. Why do R and MATLAB seem so weird to me? Are there any other major issues that you've noticed that may make these languages come off as strange to hardcore programmers? When their use is necessary, what are some good survival tips? Edit: I'm seeing one issue from some of the answers I've gotten. I have a strong personal preference, when I analyze data, to have one script that incorporates the whole pipeline. This implies that a general purpose language needs to be used. I hate having to write a script to "clean up" the data and spit it out, then another to read it back in a completely different environment, etc. I find the friction of using MATLAB/R for some of my work and a completely different language with a completely different address space and way of thinking for the rest to be a huge source of friction. Furthermore, I know there are glue layers that exist, but they always seem to be horribly complicated and a source of friction.

My scenario is ok if got a record in EDW as below Key1 Key2 Code Value EffectiveDate EndDate CurrentFlag 100 555 01 AAA 2010-01-01 11.00.00 9999-12-31 Y 100 555 02 BBB 2010-01-01 11.00.00 9999-12-31 Y This need to be loaded into DM by pivoting it as key1 and key2 combinations makes Natural key for DM SK NK 01 02 EffectiveDate EndDate CurrentFlag 1 100-555 AAA BBB 2010-01-01 11.00.00 9999-12-31 Y My ssis package does this all good pivoting... looking up the incoming NK in DIM.. if new will insert .. else with further lookup with effective date and determine if the incoming for same natural key got any new (change) in attribute.. if so updates the current record byy setting its end date and insert the new one with new attribute value and pulling the recent records values for other attributes. My problem is if the same natural key comes twice with same attribute in single extract my first lookup which on natural key .. will let both records pass and try to insert.. where its fails. If i get distinct records on NK the second is not picked and need to run package again. So my question how can i configure lookup or alernative way to handle this scenario when same NK comes twice in single extract, would be able to insert first record if not exists in Dim table and for second one should be able to updated with the changes with reference to one inserted above. Not sure this makes sense what am trying to explain. Will attached the screenshot once back to work desk (on monday). Thanks

• Calling another ruby script from a ruby script

  - by Andrew Grimm

  In ruby, is it possible to specify to call another ruby script using the same ruby interpreter as the original script is being run by? For example, if a.rb runs b.rb a couple of times, is it possible to replace system("ruby", "b.rb", "foo", "bar") with something like run_ruby("b.rb", "foo", "bar") so that if you used ruby1.9.1 a.rb on the original, ruby1.9.1 would be used on b.rb, but if you just used ruby a.rb on the original, ruby would be used on b.rb? I'd prefer not to use shebangs, as I'd like it to be able to run on different computers, some of which don't have /usr/bin/env.

Edit: I didn't mean load or require and the like, but spawning new processes (so I can use multiple CPUs).
