  • Is OO-programming really as important as hiring companies place it?

    - by ale
    I am just finishing my masters degree (in computing) and applying for jobs.. I've noticed many companies specifically ask for an understanding of object orientation. Popular interview questions are about inheritance, polymorphism, accessors etc. Is OO really that crucial? I even had an interview for a programming job in C and half the interview was OO. In the real world, developing real applications, is object orientation nearly always used? Are key features like polymorphism used A LOT? I think my question comes from one of my weaknesses.. although I know about OO.. I don't seem to be able to incorporate it a great deal into my programs. I would be really interested to get peoples' thoughts on this!

  • On-line Based Conferencing For Admin Panel

    - by Tim Marshall
    Working on my admin panels work station section which will allow the admin to use simple office tools such as word editors, calculators and whatnot. Under this section of the admin panel, I would like to add a conferencing feature which will allow any administrator to connect with another administrator 1-2-1 under the 1-2-1 Conferencing section, or to join a meeting under 'live meeting' section. Upon my search for on-line based, I found there are all these, what seem to be great applications out there, however not all of them are on-line based, and come with a price! I would like to a purely on-line based conferencing/meeting/1-2-1 feature which will allow administrators to communicate via text or sound, stream their video, share their screen and sending of files. I know this sounds like a big feature, and I am not asking for someone to answer by programming one for my website! Does anyone know my best solution to progress to having this feature on my website, any tutorials or free to use, free to modify web plugins? Thank you for your help, Best Regards, Tim

  • Waiting for Windows 8: A Long, Hot Summer

    - by andrewbrust
    Microsoft has revealed some things about Windows 8, and revealed a part of the developer story for new Windows 8 “tailored,” “immersive” applications.  In retrospect, very little was shared.  The bit that was revealed to us is that those applications can be developed using a combination of HTML 5 and JavaScript.  Not much else was said, except that additional details would be revealed at Microsoft’s //Build/ conference in Anaheim, California in September. This has left a lot of people in suspense, and it seems that suspended state is going to last all summer.  The problem, of course, is that in the absence of hard information, people fill the void with Speculation, Rumor and Gloom.  That’s a bit like Fear, Uncertainty and Doubt, except that it’s self-imposed by the Microsoft community and not planted by Microsoft’s competitors. This is a less-than-perfect situation.  Not only is it causing developers to worry about the value of their skill sets, but I am already hearing from consulting shops that customers are getting nervous too and, in extreme cases, opting for non-Microsoft tools for their projects as a result.  I’m also hearing from dev tool ISVs that sales have suffered as a result. It’s quite possible that the customers moving off .NET wanted to do so anyway and it’s also possible that dev tool ISVs are suffering slower sales this year due a slowed rate of economic recovery. Without hard information, tend to people interpret things negatively.  Actually, that’s the major point in all of this. While there is multitude of opinions about what the Windows 8 development platform will look like once fully revealed, there is an emerging consensus around one thing: it sure would help if Microsoft revealed more of its strategy…just enough to quash absurd rumors, stabilize the .NET ecosystem and get people to stay calm. We’ve had some reassurances thus far: there will be a Windows desktop mode; we’ll still have Windows Explorer, we’ll still run Office, we’ll still have a task bar, and all the skills and tools we use now will still work there.  But with reassurances like that…people still feel insecure.  Because telling us that Windows 8 will have what is essentially a “classic” mode sure makes it sound like today’s skill sets will soon be “classic” too…and then maybe they’ll just become obsolete. Humans find change scary; it’s natural.  And when left alone with their fears – because no one is saying anything to dispel them – people can go from frightened to paranoid, and can start to viewing things in a downright conspiratorial light.  It would be great if Microsoft stepped into the void now and told us what is coming – especially because whatever they tell us is bound to be at least a little better than what people think they are going to hear. I don’t know what the announcements will be, but I do have it on authority, from a number of sources, that Microsoft isn’t gong to talk until //Build/.  That means no news until September September 13th.  Nothing until after Labor Day.  You get zippo until after the Back-to-School sales are done. What to do?  Try not to let the dark voices of gloom and doom fill your head.  Even in the absence of answers, we still have some important facts: The .NET developer community is huge. Microsoft’s customers have major investments in .NET, and in .NET skills. Political infighting in Redmond might make for irrational decisions, but ultimately public companies can’t just alienate their advocates and piss off their customers.  Spite doesn’t trump fiduciary responsibility. The computing device markets are changing, software is changing, software business models are changing and developers are changing.  Microsoft has to keep up. The HTML + JavaScript community is huge too, and it includes many of the “changed” developers. Public companies can’t ignore new markets nor the popular standards that can help them enter those new markets.  Loyalty doesn’t trump fiduciary responsibility either. If Microsoft can appeal to new developers, then it should. If Microsoft can keep catering to its existing developers and customers -- not just through legacy support, but also through empowering futures -- then it probably will. You don’t have to shove your old friends out into the rain to make room for new ones; you can bring those new constituents in under a bigger tent.  I hope Microsoft will enlarge the tent, and I have trouble imagining why it would not.

  • Un nouveau type d'attaques par injection SQL plus sophistiquées découvert par un cabinet de sécurité toucherait plus de 20.000 sites

    Un nouveau type plus sophistiqué d'attaques par injection SQL Découvert par un cabinet de sécurité, il toucherait plus de 20 000 sites Les attaques par injection SQL font partie des vulnérabilités les plus courantes dont sont victimes les applications Web. Mais cette « popularité » fait aussi que plusieurs mécanismes de défense ont été mis au point et sont couramment utilisés. Face à cette situation, des pirates auraient développé une nouvelle variante d'attaque par injection SQL. Elle utilise, selon la récente découverte de la société de sécurité Web Armorise, une forme simple de peer-to-peer. Traditionnellement, les attaques par injection SQL sont effectuées en exploitant...

  • System that splits passwords across two servers

    - by Burning the Codeigniter
    I stumbled upon this news article on BBC, RSA splits passwords in two to foil hackers' attacks tl;dr - a (randomized) password is split in half and is stored across two separate servers, to foil hackers that gained access to either server upon a security breach. Now the main question is, how would this kind of system would be made... codespeaking, for PHP which I commonly develop on my web applications, the database password is normally stored in a configuration file, i.e. config.php with the username and password, in that case it is understandable that the passwords can be stolen if the security was compromised. However when splitting and sending the other half to the other server, how would this go on when making a communication to the other server (keeping in mind with PHP) since the other server password would be stored in a configuration file, wouldn't it? In terms of security is to keep the other server password away from the main one, just exactly how would the main server communicate, without exposing any other password, apart from the first server. This certainly makes me think...

  • What are the default layout settings in gnome-terminal?

    - by Exeleration-G
    I want to replace gnome-terminal fully by lxterminal. I've started by changing the default terminal emulator. So I ran sudo update-alternatives --config x-terminal-emulator, and chose lxterminal. After that, I ran dconf-editor and went to org - gnome - desktop - applications - terminal and changed gnome-terminal to lxterminal and removed the -x in the exec arg part. The only problem though, is that by default, lxterminal doesn't look like gnome-terminal. What are gnome-terminal's default layout settings? I'm especially looking for the hexadecimal colour codes for both text and background.

  • Calling Web Service with Complex Parameters in ADF Mobile

    - by Shay Shmeltzer
    Many of the SOAP based web services out there have parameters of specific object types - so not just simple String/int inputs. The ADF Web service data control makes it quite simple to interact with them. And this applies also in the case of ADF Mobile. Since there were several thread on OTN asking about this - I thought I'll do a quick demo to refresh people memory about how you pass these "complex" parameters to your Web service methods. By the way - this video is also relevant if you are not doing mobile development, you'll basically use the exact same process for building "regular web" ADF applications that access these types of Web services. One more thing you might want to do after you create the page is look at the binding tab to see the method call in there, and notice the parameters for it in the structure property. Go and look at their NDValue property to get the complete picture.

  • JSIL - a Dot Net to JavaScript translator

    - by TATWORTH
    JSI is described at http://jsil.org/ as:"JSIL is a compiler that transforms .NET applications and libraries from their native executable format - CIL bytecode - into standards-compliant, cross-browser JavaScript. You can take this JavaScript and run it in a web browser or any other modern JavaScript runtime. Unlike other cross-compiler tools targeting JavaScript, JSIL produces readable, easy-to-debug JavaScript that resembles the code a developer might write by hand, while still maintaining the behavior and structure of the original .NET code. Because JSIL transforms bytecode, it can support most .NET-based languages - C# to JavaScript and VB.NET to JavaScript work right out of the box."

  • vlc issue with unity

    - by bob
    I'm using ubuntu 12.04 with unity 3d. I am having troubles to lock vlc (version: VLC media player 2.0.1 Twoflower (revision 2.0.1-0-gf432547)) to the left panel. It doesn't behave the same way other applications do. This is a fresh install from the repo, I didn't change any settings. Ubuntu 12.04 is also a fresh install. For example, (left) clicking on it doesn't bring it to front, but creates a new instance (this in particular is very annoying, if it gets behind another window, that happens to be maximized, there is no way to bring it back up). It also doesn't have a right arrow to say the number of instances there is. Any way around that ?

  • Reduce boot time between grub menu and login screen

    - by Sudheer
    I use Ubuntu 14.04 LTS version which used to boot fast at beginning but not i loads very slow. I searched for this but can't find suitable answers. so i want to reduce my boot time which is now around 1min 12sec (boot chart) overall but i noticed its taking a longtime after grub menu and before login screen. A Blank screen appears after grub waiting... then login screen appears. I want to know a way to reduce that blank screen time(or if possible remove) and get login screen as fast as possible. I already removed several of my startup applications. Getting desktop after log-in is fast. I don't want to remove unity and install light desktop envinorments like Xfce and Lxde. Here is my boot-chart image Thanks in advance

  • Secure Open Source?

    - by opatachibueze
    I want to make a delicate application of mine (an antivirus actually) open source but I want to have a control on who really obtains the source or not. Preferably they should apply and I or administrators approve their applications. Is there any online platform for this? The main reason for the control/security is to possibly prevent malware makers to easily discover how to bypass the stealth checking methods it utilizes for malware detection. Edit: I am looking for advice - possibly to hear from someone who has done something similar. Thanks!

  • New Java ME security app, Rapid Tracker, is now full version

    Rapid Protect has updated it's Java ME security app to be the full version now instead of a dumbed down version that ran on feature phones. Now, that's progress! See: Full Rapid Tracker on Java ME Here's a quote: Rapid Protect, a leading company focused on mobile based safety, security and collaboration space announces major feature enhancements to its award winning "Rapid Tracker" mobile applications. In addition to many new features, it announced availability of Full Rapid Tracker application on J2ME non-smart feature phones. Hmmm... "on J2ME non-smart feature phones". I wonder if by "non-smart" they mean another word... Perhaps, "non-iDrone-Anphoid"? Hinkmond

  • 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.

  • Building my first ASP.NET WebForms application problem

    - by user1525474
    Hi I have recently started to learn C#/ASP.NET WebForms and after reading two books I thought I was ready to create my first web application. Problem is I could not have been more wrong. Although I am not quite a beginner as a programmer and have done some programming in Java (a Monopoly game), JavaScript (using jQuery), and PHP (create templates for WordPress), I never really created something that is database driven, and I can't seem to figure where to start. I am very confident in my HTML/CSS/jQuery skills, so that is not the problem. My end goal after becoming comfortable in ASP.NET WebForms is to learn MVC, ADO.NET, and the Entity Framework, and start a career as a .NET developer. I would like if someone could tell me some tutorials that build ASP.NET WebForms applications, such as a blog, so I can see what are the steps in creating an ASP.NET WebForms database driven application. I already have to projects in mind for ASP.NET. One is building a blog and the other building a job board.

  • How to fix Fullscreen focus error in Unity?

    - by Vagrant232
    Recently, I've been experiencing an error with programs that have a fullscreen mode with low resolution (80xx600 and below) in Unity. The problem isn't valid in gnomeshell. Whenever I launch an application, unity would enlarge the screen more than it should be and would only show me the upper left corner of the screen (I only see a magnified quarter of the screen). At first I thought that it was an issue related to wine but I later found out that native applications (such as world of goo) are affected as well. Apps that taken on the full screen but have a larger resolution don't face such an issue. Is it possible to get this fixed manually? Or do I have to wait for updates?

  • how to deal with parallel programming

    Hi. I know that parallel programming is a big resource in computer graphics, with moder machines, and mayebe a computing model that will be grow up in the near future (is this trend true?). I want to know what is the best way to deal with it. there is some practical general purpose usefulness in studying processor n-dimensional mesh, or bitonic sort in p-ram machines or it's only theory for domain specific hardware used in real particular signal elaborations of scientific simulations? Is this the best way to acquire the know how for how to become acquainted with cuda or opencl? (i'm interested in computer graphics applications) and why functional programming is so important to understand parallel computing? ps: as someone has advice me i have forked this discussion from http://stackoverflow.com/questions/4908677/how-to-deal-with-parallel-programming
