  • How to organize a programming course?

    - by Bogdan Gavril
    I've been given the task to train our manual testers to become developers in test (write test automation!). some have basic programing knowledge (either dabbling in PHP or reading stuff) and some who have no experience. Note that I do have teaching experience, but with real students, not employees, and one concern is that they will not put extra hours except the 20% management gave them for the transition. Language to be taught and used: C# We have 8 hours per week to do this and should decide if they will make it in 2 months. I am thinking of a combined approach: use a manual such as Head First C# (although I'm not happy with the labs, they're mostly games and I don't want to add UI complexities) have them read from the manual do labs with them, solving more and more difficult problems and explain the theoretical stuff as well have them do a bigger project towards the end Some questions: do you have a better suggestion as far as manuals go? do you have a better aproach? Focus less on labs? what kind of assesments should I use and how often? should I let them do a bigger project (bank system or small game) and how much time should I invest in that? ideeas on labs? other resources ? Any other tips would be most welcomed! Thanks!

  • C Programming Language and UNIX Pioneer Passes Away

    According to a statement given to the New York Times by Ritchie's brother Bill, Dennis Ritchie was living alone at his home in Berkeley Heights, New Jersey, prior to his death. Richie's health had reportedly deteriorated, and his last years were made difficult by the after effects of treatments for prostate cancer and heart disease. In addition to his brother Bill, Ritchie is survived by his sister Lynn and his other brother John. Dennis Ritchie was born in Bronxville, New York, in 1941. His father was an engineer with Bell Labs and his mother was a homemaker. His family eventually moved...

  • Community Programming

    - by James Hill
    Background I just began working for a religious non-profit organization. As with most non-profits, the organization is resource-poor and has no IT department to speak of. In my two months here I've received 20 requests for websites, apps, and internal automation. Many of these 20 requests have merit and would benefit the organization. I'm a .net web developer and as such the open source community is relatively foreign to me... Question For the sake of this question, lets say I'm talking about building a single, large, website. Does software (web based, hopefully) exist that would allow me to post requirements and assets (graphics and CSS) for a site, and then invite programmers to participate in the sites development? As a simple example, I could post the requirements and data for the about us page and an individual would indicate that they could/would fulfill the requirement. Upon completion, they could upload the new source code to the shared repository (github).

  • How to practice object oriented programming?

    - by user1620696
    I've always programmed in procedural languages and currently I'm moving towards object orientation. The main problem I've faced is that I can't see a way to practice object orientation in an effective way. I'll explain my point. When I've learned PHP and C it was pretty easy to practice: it was just matter of choosing something and thinking about an algorithm for that thing. In PHP for example, it was matter os sitting down and thinking: "well, just to practice, let me build one application with an administration area where people can add products". This was pretty easy, it was matter of thinking of an algorithm to register some user, to login the user, and to add the products. Combining these with PHP features, it was a good way to practice. Now, in object orientation we have lots of additional things. It's not just a matter of thinking about an algorithm, but analysing requirements deeper, writing use cases, figuring out class diagrams, properties and methods, setting up dependency injection and lots of things. The main point is that in the way I've been learning object orientation it seems that a good design is crucial, while in procedural languages one vague idea was enough. I'm not saying that in procedural languages we can write good software without design, just that for sake of practicing it is feasible, while in object orientation it seems not feasible to go without a good design, even for practicing. This seems to be a problem, because if each time I'm going to practice I need to figure out tons of requirements, use cases and so on, it seems to become not a good way to become better at object orientation, because this requires me to have one whole idea for an app everytime I'm going to practice. Because of that, what's a good way to practice object orientation?

  • Is it worth to learn programming for windows?

    - by Herr Kaleun
    as a programmer, i was skeptical about (Microsoft) desktop software back in the early 2000s (i was a kid then) and yet, i was right. So i advanced to PHP in 2004 and began working on Web applications. When i look at the software world today, i really can't understand, how software for Microsoft or call it, "windows" should have a future. Is it still worth, learning it? I have a strong feeling that, in about 3-4 years, mac will have the dominance in the Personal Computer market. If i am wrong, please correct me. Thanks!

  • Automatically generated /etc/hosts is wrong

    - by Niels Basjes
    I've created a kickstart script to install CentOS 5.5 (32bit) in a fully automated way. The DNS/DHCP setup correctly gives the system the right hostname in both the forward and reverse lookups. dig node4.mydomain.com. +short 10.10.10.64 dig -x 10.10.10.64 +short node4.mydomain.com. In the state the installed system is right after the installation completed is as follows: cat /etc/sysconfig/network NETWORKING=yes NETWORKING_IPV6=yes GATEWAY=10.10.10.1 HOSTNAME=node4.mydomain.com echo ${HOSTNAME} node4.mydomain.com cat /etc/hosts # Do not remove the following line, or various programs # that require network functionality will fail. 127.0.0.1 localhost.localdomain localhost ::1 localhost6.localdomain6 localhost6 10.10.10.64 node4 My problem is that this automatically generated hosts file is slightly different from the way I want it (or better: the way Hadoop wants it). The last line should look like this: 10.10.10.64 node4.mydomain.com node4 What do I modify where to fix this? Thanks.

  • ubuntu server 10 - slow and can't remove desktop environment

    - by Alex
    i'm running ubuntu server 10.10 with the desktop environment. simple page requests are taking over 5 seconds even when connecting to the server through our local network. i believe this is partially related to having the desktop environment installed, as the server worked faster (but not as fast as it should considering that it's on the local network), but tasksel fails every time (aptitude failed 100). my knowledge of networking and linux in general is limited. would really appreciate ideas on how i can troubleshoot this problem. oh also, in the system monitor, one of the processors is almost always around 100%. i doubt this is normal too....

  • How to enable printer settings over Jetdirect on HP 4100N

    - by zsero
    I have a HP 4100N printer and I am using it over network. Previously I was able to access the printer settings over internet, but now the only thing visible is Device Info and Networking. I can connect to the web server and I can set all the network related settings, but that's not what I want. There should be a supplies, config, print info, etc. page, what are not visible now. Can you tell me what setting should I set to enable this printer config page on the webserver? The printer is a HP 4100N and the network card is J4169A (Jetdirect 610n).

  • Use dns suffixes only on certain wireless networks?

    - by eidylon
    Hello all, quick question. I'm a software guy and networking is all black magic to me! I have a laptop which I use at home and at the office. In order to be able to more easily reference our servers at work, I have our domain name in the DNS suffixes on my TCP/IP settings on my wireless connection. This all works beautifully and I can reference our servers simply by name only. Now the problem... When I go home, it still has those suffixes in there, and I cannot access other servers because it appends the DNS suffixes to the server names. Is there a way I can set up DNS suffixes so that they are only applied when connected to a certain wireless network (I'm thinking by SSID).

  • Good text editor for Ruby on Rails programming?

    - by Andrew
    I'm trying to find a text editor that I can use for doing Ruby on Rails development. I have been using TextMate on my Mac and would love to find something that even comes close to that experience. My Ubuntu laptop is a little old, and doesn't have a lot of memory, so I need something lightweight. I don't need/want a bloated IDE because the performance on my slow laptop would be terrible. It would be nice if this text editor had: Syntax highlighting A project/file browser view to be able to open files in my project Keyboard shortcuts (don't need them as much)

  • Where can I find programming work online ?

    - by explorest
    I have setup an ideal, quiet, non-interrupting environment at home. I am extremely productive here. I dont want to leave my home, not my room, not even my couch. How/where do I find work online so that I don't have to travel to it? Kindly post about your own personal experiences. Have you done it full time from home? Where and how? I am outside United States in a third world country so a lower pay is not an issue. The issue is the work-enviroment.

  • Where to look for a programming partner?

    - by David
    Say that you want to start a new project (I'm talking about a serious project — e.g if you had an idea that seems good and profitable — not about something you start just to learn a new technology or just for your enjoyment) but you don't feel like you can do it alone since, for example, you lack the experience or the technical skills to go through all the phases needed to go from the idea to the final product. Say also that you don't simply want to hire someone. You want someone who can be as passionate as you in the job, that is “proficient” in and enthusiast of the same technologies as you are and that possibly has a background similar to yours (e.g. you both are students, you both come from a prestigious univerity or just you're both Star Trek nerds). So, basically you don't want a person to tell what to do (e.g. “implement this and that, slave!”) but someone who can be inspiring and bring something new and important to your project. Someone to go with you from the earliest stage — from clearly shaping the project's philosophy to drawing mockups etc. Someone who agrees to share the outcome of the project, that strongly believes in the idea behind it and is completely 50-50 with you. Now the question is: how to improve your chances of finding this person (or persons)? Where would you look at first? For example, if you had a lot of funds and were looking for someone to hire, you'd maybe post an ad in SO careers or jobs.73signals; if you already had a team and were looking for funding, you'd start a project on kickstarter or indiegogo, or you'd go to some startup event. But if you had to find a good partner (and programmer, of course) for you're project, where would you start looking? Which strategies would you use?

  • C++ Programming: Better Accessibility with High DPI Support and MFC 10

    A number of factors are driving the requirement for applications to correctly support high DPI settings--increased monitor resolutions are making it more difficult for users to read text on the screen, compliance with disability access legislation is an increasingly important factor for corporations, and users are now expecting applications to behave well at higher DPI settings. MFC 10 and Visual C++ 2010 have built-in support for high DPI, making the development of a DPI-aware application quicker and more simple.

  • Network access to VM only from host ...

    - by Jamie
    I'm trying to do some testing of Ubuntu 10.04 Beta 2 Server in a VMWare environment. The host is XP, and the VM software is VMPlayer. Problem is, I want to be able to see the VM from the network, not just from the host. I can SSH into the VM from the host, but from any other machine on the network I can't even get the VM to respond to a ping. Going the other way (from the VM out) isn't a problem at all. The VM software did an 'easy installer' so I'm not really sure what was going on with the networking. Suggestions?

  • Is `break` and `continue` bad programming practice?

    - by Mikhail
    My boss keeps mentioning nonchalantly that bad programmers use break and continue in loops. I use them all the time because they make sense; let me show you the inspiration: function verify(object) { if (object->value < 0) return false; if (object->value > object->max_value) return false; if (object->name == "") return false; ... } The point here is that first the function checks that the conditions are correct, then executes the actual functionality. IMO same applies with loops: while (primary_condition) { if (loop_count > 1000) break; if (time_exect > 3600) break; if (this->data == "undefined") continue; if (this->skip == true) continue; ... } I think this makes it easier to read & debug; but I also don't see a downside. Please comment.

  • Connect to wired and wireless networks at same time, Ubuntu

    - by Gary Chambers
    Currently, I have a media PC running Ubuntu 10.04 that I am trying to connect via a wired network cable directly to a NAS box, and wirelessly to the router. This works no problem after I run sudo /etc/init.d/networking restart but I can't get both interfaces to come up on system startup. My /etc/network/interfaces file reads as follows: auto eth0 iface eth0 inet static address 10.0.1.2 netmask 255.255.254.0 broadcast 10.0.1.255 network 10.0.1.0 auto wlan2 iface wlan2 inet dhcp As I say, I know this works, because I can get it to work by restarting the network interfaces, but I can't bring them both up on system startup. Does anyone know why this might be?

  • Any enlightenment for understanding Object Oriented Programming? [closed]

    - by ????
    I studied computer science near the end of 1980s, and wasn't taught OOP that formally. With Pascal or C, when I understand the top-down design of functions, and the idea of black box, then everything just seem to make sense, as if there is a "oh I get it!" -- some kind of totally getting it and enlightenment feeling. But with OOP, all I know was the mechanics: the class, instance, method, inheritance, polymorphism, encapsulation. It was like, I knew all the "this is how it is", but never had the feeling of "I totally get it", the enlightened feeling. Would somebody be able to describe it, or point to a chapter in some book or paper which talks about OOP so that the reader can feel: "I totally get it!" on OOP?

  • how do we clear new programming concept

    - by Sarang
    In IT world, new latest technologies are generated daily. Every time, every programmer need to learn something & then clear it conceptually to implement. All new technologies are built on some basic concepts. But, these technologies have their own area of development & a developer is supposed to grasp it from very basic. This seems like starting from very beginning to reach till current. What is the best & fast way to learn and grasp a new developed technology ?

  • What's your most controversial programming opinion?

    - by Jon Skeet
    This is definitely subjective, but I'd like to try to avoid it becoming argumentative. I think it could be an interesting question if people treat it appropriately. The idea for this question came from the comment thread from my answer to the "What are five things you hate about your favorite language?" question. I contended that classes in C# should be sealed by default - I won't put my reasoning in the question, but I might write a fuller explanation as an answer to this question. I was surprised at the heat of the discussion in the comments (25 comments currently). So, what contentious opinions do you hold? I'd rather avoid the kind of thing which ends up being pretty religious with relatively little basis (e.g. brace placing) but examples might include things like "unit testing isn't actually terribly helpful" or "public fields are okay really". The important thing (to me, anyway) is that you've got reasons behind your opinions. Please present your opinion and reasoning - I would encourage people to vote for opinions which are well-argued and interesting, whether or not you happen to agree with them.

  • C Programming matrix

    - by Bilal Khan
    In this program the user enters the # of columns of the matrix and then the entries of the matrix. So, for example, if the user enters 2 for column # and 1 2 3 4 for entries then the program develops a 2 by 2 matrix with 1 2 3 4 as entries. My program works perfectly in such a case. However, if the user for example had only entered 1 2 3 then my program makes a matrix with garbage values. I would like the program in such a case to exit the program. It is a simple question, but it has me baffled. #include<stdio.h> #include<stdlib.h> int main() { int m,x, n, c = 0, d,k, matrix[10][10], transpose[10][10], product[10][10]; printf("Enter the number of columns of matrix "); scanf("%d",&m); if(m<=0){ printf("You entered a invalid value."); exit(0); } else{ printf("Enter the elements of matrix \n"); for( c = 0 ; c < 10 ; c++ ) { for( d = 0 ; d < m ; d++ ) { scanf("%d",&matrix[c][d]); if (matrix[c][d] == 99) // 'x' is character variable I declared to use as a break break; // c = c+1; } if (matrix[c][d] == 99) break; } } printf("\nHere is your matrix:\n"); int i; for(i=0;i<c;i++) { for(d=0;d<m;d++) { printf("%3d ",matrix[i][d]); } printf("\n"); }
