  • What are some good examples of using pass by name?

    - by Paul
    When I write programs I using pass by value or pass by reference always seem to be logical methods. When learning about different programming languages I came across pass by name. Pass by name is a parameter passing method that waits to evaluate the parameter value until it is used. See Stack Overflow pass by name question for more information on the method. What I would like to know is: what are some good examples and/or reasons to use pass by name and should it be re-introduced into some more modern languages.

  • How much C/C++ knowledge is needed for Objective-C/iPhone development?

    - by BFree
    First, a little background. I'm a .Net developer (C#) and have over 5 years experience in both web development and desktop applications. I've been wanting to look into iPhone development for some time now, but for one reason or another always got side tracked. I finally have a potential project on the horizon, and I'm now going full steam ahead learning this stuff. My question is this: I haven't done any C/C++ programming since my schooling days, I've been living in managed land ever since. How much knowledge if any is needed to be successful as an iOS developer? Obviously memory management is something that I'll have to be conscious about (although with iOS 5 there seems to be something called ARC which should make my life easier), but what else? I'm not just talking about the C API (for example, in order to get the sin of a number, I call the sin() function), that's what Google is for. I'm talking about fundamental C/C++ idioms that the average C# developer is unaware of.

  • Testing HTML5 and javascript code for iPhone and Android devices

    - by Pankaj Upadhyay
    I have developed a simple HTML5 webpage that uses a javascript file. This is a fun learning page so I wanted to know as to how will they show up on mobile devices like iPhone and Android smartphones. The pages are hosted on a server and i have tested the thing on my desktop. But, how can i test the same for these mobile devices. i.e. how the page will look on mobile and stuff. I don't have an iPhone or Android. There is no serious development going in here so i was thinking if there is some free website or tool that acts as a iPhone or android browser. The main aim is just to see how the webpage will show up on an android phone.

  • Copying VBoxAdditions to usr/share/virtualbox folder

    - by Joe
    Since for some reason VBox does not find the Additions on the internet, I was trying to install them in the Ubuntu directory Vbox is looking for them - which is: usr/share/virtualbox but I am denied permission to do so. Any way around it? I am relatively new to ubuntu (know how to use the GUI, but still learning how to talk to the machine proper, so many things will be new to me; used to be power user/analyst for MS Windows, 98-Vista, so not a PC newbie, but still I'd say Linux newbie). Any suggestion is more than welcome! Thanks Joe

  • Where can I learn image processing? [on hold]

    - by Little Child
    I am learning image processing on my own and I have managed to teach myself a fair few things like: Making images grayscale using 3 different methods Applying a 'pixellate' filter Applying a 'pointillize' filter Make images out of lines Now, I want to take my knowledge further but I do not know how. Adding more information: I am interested in making software like Photoshop or Gimp (although it won't be half as powerful as these 2). So, I want to learn to apply various creative effects to an image. Can someone please suggest resources for this??

  • Trouble installing downloaded program

    - by Hamlette
    I purchased and downloaded Celtx and I'm having trouble installing it (in Ubuntu 13.04). I'm a Linux newbie (literally had it for four days) so please be kind and don't assume much experience with the command line, I'm still learning. The folder with all related files/packages etc. is under "Downloads" and I have tried several commands to try and install but I'm just not doing it right and would appreciate help with exactly what command(s) to use. Sudo apt-get install celtx did not work. I'm assuming I'm missing a step somewhere.

  • Web services Authentication Jungle

    - by redben
    I have been doing some research lately about best approaches to authenticating web services calls (REST SOAP or whatever). But none of the Approaches convinced me... But i still can't a make a choise... Some talk about SSL and http basic authentication -login/password- which just seems weird for a machine (i mean having to assign a login/password to a machine, or is it not ?). Some others say API keys (seems like these scheme is more used for tracking and not realy for securing). Some say tokens (like session IDs) but shouldn't we stay stateless (especially if in REST style) ? In my use case, when a remote app is calling one of our web services, i have to authenticate the calling application obviously, and the call must - if applicable - tell me which user it impersonates so i can deal with authorization later. Any thoughts ?

  • Can aynone tell me what exactly 32bit/64bit and x86 and AMD64 have to do with the different choices on the download site of Ubuntu?

    - by Elysium
    SORRY for the newbie question, but I am still learning. I am wondering if x86 simply refers to the intel CPUs and AMD64 simply refers to the AMD CPUs? While....32bit and 64bit to the processor types? I was trying to download the intel 64bit version of the Ubuntu installer, but it wont give the option of x86 and AMD64....only the 32bit and 64bit can be chosen. Does this mean that someone with an Intel CPU and another person with an AMD CPU will download the same install file? (obviously depending on the bit version of their CPUs this might differ....but that's another thing).

  • low level api or graphics library?

    - by German
    Well, I want to learn game development, I've already know a little bit about xna, ogre and DX but, I want to choose one of them and stick with it. I'm not trying to make a "directx vs xna, ogre vs opengl, etc." thread. Some people told me that it's better to learn an engine like Ogre because you can develop games directly and you don't have to worry about the low level details, I know that. Other people told me that it's better to learn a low level api before learning something like Ogre because you will able to understand how it works. Is it valuable to have experience with Ogre or another engine but don't know anything about a low level api? What do you recommend me? Thanks in advance.

  • What undergraduate course to choose for a mature programmer returning to study

    - by Dve
    I have been developing applications (mostly web-based) for almost 10 years now and have learnt pretty much everything I know through experience (and the internet!). I wouldn't call myself an advanced programmer, but I am quite proficient in several languages (C#, Javascript, Ruby, HTML/CSS etc) and spend a quite a bit of time working on personal projects and reading countless books & articles. I am looking to emigrate to Canada, hopefully Vancouver (im from the UK) and one way would be on a student visa, if I was going to be studying for a minimum of 2 years. Having never been to university or achieved anything higher than A-Levels I am quite tempted by this path. The thought of learning is more exciting to me now than it was 10 years ago! What would be people recommend as a good undergraduate course to take that would complement this career path? Would Math be beneficial, if so which area of Math? TL;DR What undergraduate course/area of study would complement 10 years of (mostly web-based) programming experience?

  • Read from POS Devices

    - by Garhwali Bhai
    Hi Experts, What would be the best design for a Java web based application to read Check or Credit Card from POS Devices which are configured/installed at client machine? The design which I have decided is: When cashier selects payment mode as 'Check' or 'Credit Card' open a pop-up. From pop-up, I am calling an Applet through JNLP which implements JPOS API to communicate with POS devices at client machine. When cashier swipes or inserts check, Applet class read them and send the information back to the pop-up window. Pop up window call the parent window, populate all the required field and close the pop-up.

  • University teaches DOS-style C++, how to deal with it

    - by gaidal
    Half a year ago I had a look at available programming educations. I chose this one because unlike most of the choices: The majority of the courses seemed to be about something concrete and useful; the languages used are C++ and Java which are platform-independent; later courses include developing for mobile devices and a course on Android development, which seemed modern and relevant. Now after two introductory courses we're just starting with C++, and my programming professor seems a bit weird. He's tested us on things like "why should you use constants" and "why are globals bad" in a kind of mechanical way, without much context, before teaching actual programming. His handouts use system("pause"), system("cls"), and getch() from some conio.h that seems ancient according to what I've read. I just did a task that was about printing the "ASCII letters from 32 to 255" (huh?), with an example picture showing a table with Windows' Extended ASCII - of course I got other results for 128-255 on my Arch Linux that uses Unicode, and this isn't mentioned at all. I don't know, it just doesn't seem right... As if he is teaching programming because he has to, perhaps? Should I bring such things up? Hmm. I was looking forward to learning from someone who really knows stuff, and in an academic, rigorous way, like SICP or something. Aren't professors in programming supposed to be like that? I studied math for a while and every teacher and assistant there were really precise about what they said, but this is my second programming teacher that is sort of disappointing. Oh well. Now, question: Is this what to expect from universities or Not OK, and how do I deal with it? I have never touched the language C++ (or C) until now, and am not the right person to jump up and say "This is So Wrong!", so if I google something and find 10 people who say "xxx is blasphemy", how do I skillfully communicate this? I do think it would be better for those classmates who are total beginners not to learn bad habits (such as these vibes of total ignorance of other platforms!) during the upcoming courses, but don't want to disrespect the teacher. I don't know if it's reasonable or just cocky to bring up things like "what about other platforms?" or "but what about this article or stackoverflow answer that I read that said..." for every assignment? Or, if he keeps ignoring non-Windows-programming, should I give up and focus on my own projects or somehow argue that this really isn't OK nowadays? Are there any programming teachers out there, what do you think? By the way these are web-based courses, all interaction between teachers and students takes place in a forum. EDIT: A few answers seem to be making some incorrect assumptions, so maybe I should add a few things. I have been doing programming for fun on and off for 10 years, am pretty comfortable in 3 languages and read programming blogs et c regularly. Also, I feel kind of done being a student, having a degree in another field. I just need another, relevant diploma to work as a programmer, so I'm going back for that. Studying computer science for 5 years is not for me anymore, even though I enjoy learning and solving problems in my free time. Second, let me highlight that I don't expect it to be like the industry at all, quite the contrary. I expect it to be academic, dry and unnecessarily correct. No, it's not just math. Every professor I have had in math, or Japanese (major) or Chinese (minor) have been very very academic, discussing subtle points for hours with passion. But the courses I'm taking now and a previous one in programming don't seem serious. They neither resemble industry NOR academia. That is the problem. And it's not because I can't learn programming anyway. Third, I don't necessarily want to learn C++ or Android development, and I know I could teach myself those and anything else if I wanted to. But I am going back to school anyway, and those platform-independent languages and mobile stuff made me think that maybe they're serious about teaching something relevant here. Seems like I got this wrong, but we'll see.

  • What to choose for beginner: PHP/Python/Ruby

    - by Nai
    I'm a beginner teaching myself to code but I would like he insight of the PSE community and helping choose where to start. My main objective is to be able to create a basic website to first test my business idea and from there iterate on it quickly to minimise my learning time. The most important criteria for me is speed. An example of speed would be pre-built components available open source and not having to write one from scratch. From my research, this seems to be a death match between the following languages and frameworks: PHP and CakePHP Python and Django Ruby and Rails Assumptions: I am going to be equally good (or bad) in all 3. It is going to be equally easy to find competent developers in either language. I know this to be false already by lets assume that it is. This question is not meant to karma whore as I've seen how passionate some of these standoff questions have been and I'll be happy to turn it into a community wiki.

  • How to properly shield a Product Owner from outside?

    - by xsAce
    Update: We are a very small team (3 people) and thus I (Scrum Master) and the Product Owner are also developers doing some coding. We are aware of this situation and we are actively trying to recruit some new talents. But it's hard! Meanwhile... we need to adapt... so my question: The Product Owner complains about having too much outside noise (mainly stakeholders feature requests), and he can't focus on the sprint realisation. We agree that we should try to educate people on our process implications (sprint durations and product backlog), to reduce the noise. But as a Scrum Master, how am I supposed to shield a PO from outside? Isn't he supposed to be in contact with the management and business? Also, if people outside don't want to waste too much time learning agile, what is the best way to educate them?

  • Crappy school, what to do? [closed]

    - by zhenka
    I started programming fairly late. I am 24 years old and about to graduate from a local public university with a really poorly designed curriculum and teachers. Most of the work felt like busy work, and no matter how much I try, it all feels like a waste. I know what a good curriculum looks like. I know what books I should read, but alas it's not so in my university. There is no way at this point that I can catch up to those graduating from places like MIT. My question and this is a serious one: what do I do? Do I just postpone learning the theory I would have learned until later and focus on software engineering skills? How important is the theory in terms of landing a job in New York? Any particular things I should focus on to land a software engineer job? I am very motivated and I just wish someone would give me the time and a chance.

  • After update, audio won't play throw hdmi cable

    - by ckhenderson
    Yesterday (June 7th) I faithfully updated a bunch of stuff through update manager (though I'm not sure what since I never read what I updated any more because I'm a bad person). Afterward, I discovered that I could no longer play audio through my tv via HDMI. The sound settings menu seems to have completely changed and the shell script that I wrote a week ago (with much pain and effort as I had never before written a shell script) to toggle between my laptop speakers and the HDMI cable output no longer works. When I type in pactl set-card-profile 0 output:hdmi-surround in the command line I get Failure: No such entity Presumably this means something with Pulse Audio changed but, while I'm learning a lot about the inner workings of Ubuntu/Linux, I'm not an expert and would love some help. EDIT: So I noticed that pacmd set-card-profile 0 output:hdmi-stereo seems to get everything working. Still, shouldn't there be a way to do this through the GUI as well?

  • Windows Forms Development - Books

    - by Scott
    So I'm reading a book for architecting applications for the enterprise from the Microsoft Press. It's a great book, and I'm learning a lot. However, it's very high level, and can be applied to a lot of different domains (not even just .NET, even though that's how the book is geared). The first project I want to develop after reading the book is a Windows Forms application in .NET 4.0. I want to use a lot of the books concepts to develop the app, but I really want a great Windows Forms dedicated book to read before starting that's really going to tell me all I need to know about developing Windows Forms apps. I found plenty of books for .NET 2.0 and stuff, but nothing for Windows Forms in the new .NET 4.0 Framework. Any suggestions?

  • Java to PHP job change [closed]

    - by Yan
    I've been working with java my entire career(8 years), web servers mostly. And there is a possibility for me to start working in environment that is generally PHP based. I've never worked with PHP before except that I wrote a simple send mail html form once or twice. Is there any benefit in learning a PHP stack or this will be a complete waste of time and degradation as a developer? No offense, but I've heard terrible things about that language and I'm afraid that if people see it in my resume later that would scare them off.

  • java web application best practices

    - by Bruce
    Hi all I'm trying to figure out the optimum way to develop and release a fairly simple web application, and I'm running into several problems. I'll outline the decisions I've made, because somewhere I've clearly gone off the rails.. Hugely grateful for any help! I have what I think is a fairly simple web application. It contains a couple of jsps that reference a couple of java beans, and the usual static html, js, css and images. Decision 1) I wanted to have a clear and clean release procedure, such that I could develop on my local machine and then release reliably to a production machine. I therefore made the decision to package the application into a war file (including all the static resources), to minimize the separate bits and pieces I would need to release. So far so good? Decision 2) I wanted things on my local machine to be as similar as possible to the production environment. So in my html, for example, I may have a reference to a static file such as http://static.foo.com/file . To keep this code working seamlessly on dev and prod, I decided to put static.foo.com in my /etc/hosts when developing locally, so that all the urls work correctly without changing anything. Decision 3) I decided to use eclipse and maven to give me a best practice environment for administering and building my project. So I have a nice tight set up now, except that: Every time I want to change anything in development, like one line in an html file, I have to rebuild the entire project and then wait for tomcat to load the war before I can see if it's what I wanted. So my questions are: 1) Is there a way to connect up eclipse and tomcat so that I don't have to rebuild the war each time? ie tomcat is looking straight at my actual workspace to serve up the static files? 2)I think I'm maybe making things harder by using /etc/hosts to reflect production urls - is there a better way that doesn't involve manually changing over urls (relative urls are fine of course, but where you have many subdomains, say one for static files and one for dynamic, you have to write out the full path, surely?) 3) Is this really best practice?? How do people set things up so that they balance the requirement for an automated, all-encompassing build process on the one hand, and the speed and flexibility to be able to develop javascript and html and css quickly, as quickly as if one just pointed apache at the directory and developed live? What do people find works? Many thanks!

  • (Pathinfo vs fnmatch part 2) Speed benchmark reversed on Windows and Mac

    - by zaf
    On a previous question the pathinfo and fnmatch functions were benchmarked and the answers all came out opposite to my benchmark results. You can read the different results with the benchmark code here: http://stackoverflow.com/questions/2693428/pathinfo-vs-fnmatch I couldn't work it out until I ran the same code on a machine running vista. The results then matched the other users. My main machine is a mac. So, my questions are: Why do we get these two different results? Could this apply to other functions?

  • Announcement: How-To Series Explaining Customizations Step By Step

    - by Oliver Steinmeier
    Yesterday we officially launched our new YouTube channel.  Today we are announcing another initiative that we have been working on for a while: to help you learn common customization tasks, we are going to publish a series of detailed How-To documents with lots of screenshots.  Many of these will also be the script for a YouTube video, giving you the choice to see it in action or go through the steps yourself guided by a PDF document. The focus of the initial set of How-Tos will be JDeveloper/ADF customizations, but over time we will expand into other areas.  Today's first document is meant to get everyone up to the point where a JDeveloper environment is up and running: a white paper that shows you how to set up JDeveloper, configure the integrated WLS domain, and make a very, very simple customization work. As always we are looking for your feedback.  Please let us know whether this is helpful for your work or learning, and what use cases you would like to see us document in these How-Tos.

    I got a problem. I'm willing to dual boot ubuntu 12.04 on my desktop. After i made a bootable USB ubuntu on it i'm going to install it. I boot it and I choose Install ubuntu roughly said. The problem is the following, It seems that when i press enter to start the install he switches of to my intergrated graphic card. I looked up in my bios what my primary graphic card selection is and it was on PCI Express (the option it supossed to be). So I'm clueless right now. I don't know how to fix this because I'm quite learning linux atm (school and by myself). Your faithfully, Clenn
