  • Moving from building internal applications as WPF to ASP NET MVC?

    - by stuartmclark
    I have worked on quite a few internal applications for my work and I have always defaulted to using WPF, but I am considering re-writing existing ones into a web app. This is so that anyone in my company can use it without having to download anything from the network. I am just wondering if this is the way forward with any development of new internal applications? So, should I stop using WPF and start using ASP.NET MVC for internal applications that a lot of people need to use?

  • How to make a license apply to a whole library?

    - by Yannbane
    I'm creating a standard library for a programming language, and I'd like to license each and every single class or function in there under the MIT license, so they're completely FOSS. All of the files reside in a single directory. Would it be enough to put a LICENSE.txt file in the same directory, containing the MIT license? Do I need to say that the following license applies to all features of the library, or is the library itself considered to be a program?

  • Is the separation of program logic and presentation layer going too far?

    - by Timwi
    In a Drupal programming guide, I noticed this sentence: The theme hook receives the total number of votes and the number of votes for just that item, but the template wants to display a percentage. That kind of work shouldn't be done in a template; instead, the math is performed here. The math necessary to calculate a percentage from a total and a number is (number/total)*100. Is this application of two basic arithmetic operators within a presentation layer already too much? Is the maintenance of the entire system severely compromised by this amount of mathematics? The WPF (Windows Presentation Framework) and its UI mark-up language, XAML, seem to go to similar extremes. If you try to so much as add two numbers in the View (the presentation layer), you have committed a cardinal sin. Consequently, XAML has no operators for any arithmetic whatsoever. Is this ultra-strict separation really the holy grail of programming? What are the significant gains to be had from taking the separation to such extremes?

  • How do I add restrictions for users to sign up before they can access web site?

    - by user1867842
    How do I get my webpage not to go back when they hit the back button and are logged out and how can I add a web page to be blocked like FACEBOOK doesn't let you get into their site with out having a page or a account with them, and if you try to put something in the url and try to go to something on their site it gives you a web page that says "you have to be logged in first" . Like I don't want someone going to the url of the "index" page before they have signed up as a member they need to make an account first then they can have access to the "index" page. How do I do this. I have a website so far that has a database and the website has 5 pages so far and two of them which is the login and sign up page which are both used with php and mysql and they work fine. How do I restrict access to the main website by first having the users sign up with me for an account.

  • "A good programmer can be as 10+ times more productive than a mediocre one"

    - by m3th0dman
    I had read an interview with a great programmer (it is not in English) and in it he said that "a great programmer can be as 100 times as good as a mediocre one" giving reason for why good programmers are very well paid and why programming companies give many facilities for their employees. The idea was that there is a very large demand for good programmers, because of the above reason and that's why companies pay very much to bring them. Do you agree with this statement? Do you know any objective facts that could support it? Edit: The question has nothing to do with experience; if you talk about one great programmer with 1 year experience then s/he should be 10 times more productive than a mediocre programmer with 1 year experience. I agree that from certain experience years onwards, things start to dissipate but that's not the purpose of the question.

  • What problems will I face if I remove the concept of interfaces from my code?

    - by Vishwas Gagrani
    I have been programming for many years but I am still not comfortable with the concept of "Interfaces". I try to use interfaces but many times I don't see a mandatory use for it. I think this is probably because the projects weren't so big, or because interfaces are more useful when teamwork is involved. So, making another attempt to understand the importance of interfaces, here is my question: What problems will I face if I remove the concept of interfaces from my code?

  • Real Time Monitoring System using .net [closed]

    - by sameer
    I need to develop the application which display the dashboard where data from various SQL DB is fetched from different servers and displayed. Now this need to happen real time we can have refresh time say 5 min. Here is my thought, suggest if anything is wrong. 1) To Develop the Windows Service to accumulate the data from various SQL Server Instance. 2) Then Persist those details into SQL DB from which Dashboard will displayed on the web page. 3) Fetch of data from Windows service will be trigger every x minutes. 4) SQL Server Instance details will be stored in SQL DB which Windows Service will be referring. Thus this approach make sense. Thanks..

  • How to use unused space in ubuntu

    - by Ravi.Kumar
    I installed ubuntu on my machine with only 80 GB of memory anticipating that I will remove it later but now I want to keep it forever (until I am frustrated with linux). I have 500 GB in my machine and now I want to use that raw 420 GB of space. How I can I do that ? with "space/memory" I am referring to secondary memory not Ram. Here is output of : sudo fdisk -l Disk /dev/sda: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders, total 976773168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000dcb77 Device Boot Start End Blocks Id System /dev/sda1 * 2048 136718335 68358144 83 Linux

  • Installation on SSD with Windows preinstalled

    - by ebbot
    I bought a laptop with this fancy SSD drive, fancy new UEFI aso. I figured at first Windows out Ubuntu in but after doing 3 DoA on 3 laptops in one day I realized that maybe keeping Windows could come in handy. So dual boot it is. And this is what I've got: Disk 1 - 500 Gb HD 300 Mb Windoze only says "Healthy" don't know what it's for. 600 Mb "Healthy (EFI partition)" 186.30 Gb NTFS "OS (C:)" "Healthy (Boot, Page File, Crash Dump, Primary Partition)" 258.45 Gb NTFS "Data (D:)" "Healthy" 20.00 Gb "Healthy (Recovery Partition)" Disk 2 - 24 Gb SSD 4.00 Gb "Healthy (OEM Partition)" 18.36 Gb "Healthy (Primary Partition)" So I'm not sure what the first partition on each drive does (the 300 Gb on the HD and the OEM Partition on the SSD. Nor do I know what Data (D:). I think the 2nd partition on the SSD is for some speedup of Windoze. I'm debating if I should shrink the OS (C:) drive to around 120 GB or so. Clear the Data (D:) and also use the whole SSD for Ubuntu. That would leave me 24 Gb for e.g. / on the SSD and some 320 Gb on the HD for /home and swap. Is this a reasonable setup? Do I need to configure fstab for the SSD differently to a HD?

  • Compiz Cube bindings don't seem to work

    - by Giancarlo Palmiotti
    I have been trying to get the 3D Cube to work however, despite setting a combination for various keys from S1 (VAIO/VAIOFW) to F7 to no avail. What is "Primary" and I am not going to use the "Rotate Cube" as I have a touchpad and I cannot use the Keyboard functions if I am correct? I've tried several other similar questions while asking this but they do not seem to work. Ubuntu-12.04.1 LTS Sincerely: Giancarlo Palmiotti

  • How do I use a 4GB USB flash drive to install Ubuntu 12.10?

    - by Logan
    I've downloaded "ubuntu-12.10-desktop-amd64" and used Pen Drive Linux to get it onto my USB. I then restarted my computer (a Windows 7 Home Premium edition) and entered the boot menu to have it boot from the Sandisk USB (it called it Sandisk Cruzer Cruzer). Linux came up and asked if I wanted to try or install. I picked install, connected to my Wi-Fi, and installed it. After my laptop restarted, Windows booted immediately. I have tried several times and cannot get a choice between the two. P.S. I have used the Windows Installer, Wubi, but at the last second it gave me some kind of error.

  • How can I get shockwave flash to work on Ubuntu 12.04

    - by John Hill
    I've tried most of the things suggested on this site and others so far. It's kind of frustrating because this is a home computer and I mainly use it for browsing the internet and watching YouTube videos. When I try to install something that might fix it, it just downloads a bunch of files and says to extract them or whatever. I'm not sure what to do with the files after I extract them. That's probably the main issue: I don't have a lot of experience working with computers at this level. I'm used to Windows, which seems to make most software installs idiot-proof. Any suggestions are appreciated!!

  • Acer Aspire One 725 - missing graphic card driver for Radeon HD 7290?

    - by Melon
    Recently I bought an Acer Aspire One 725 Netbook and installed Ubuntu 12.10 on it. I bought it, because it can run HD movies and has Full HD on external VGA port. However, movies from youtube have a really slow framerate. If you open three tabs in Opera (for example g-mail, youtube and askubuntu) it gets really laggy. My suspicion is that the driver for graphic card is missing. When I check the System->Details->Graphics the driver is unknown. After running lspci | grep VGA I get this output: 00:01.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Device 980a From what I see, I have a AMD C70 processor integrated with AMD Radeon HD 7290. Has anyone had the same problem? Do you know which drivers need to be installed for the graphics to work properly? On official Acer page there are only drivers for Win7 and Win8... Update: OK. Another attempt. I have a fresh Ubuntu 12.10. All updates done. downloaded Catalyst 12.11 beta drivers and decided to create a package. After installing package, I have this error from /var/log/Xorg.0.log: [ 13.394] (**) fglrx(0): NoAccel = NO [ 13.394] (**) fglrx(0): AMD 2D Acceleration Architecture enabled [ 13.394] (--) fglrx(0): Chipset: "AMD Radeon HD 7290 Graphics" (Chipset = 0x980a) [ 13.394] (--) fglrx(0): (PciSubVendor = 0x1025, PciSubDevice = 0x0740) [ 13.394] (==) fglrx(0): board vendor info: third party graphics adapter - NOT original AMD [ 13.394] (--) fglrx(0): Linear framebuffer (phys) at 0xe0000000 [ 13.394] (--) fglrx(0): MMIO registers at 0xf0200000 [ 13.394] (--) fglrx(0): I/O port at 0x00003000 [ 13.394] (==) fglrx(0): ROM-BIOS at 0x000c0000 [ 13.484] (II) fglrx(0): ATIF platform detected [ 13.564] (II) fglrx(0): AC Adapter is used [ 13.565] (EE) fglrx(0): V_BIOS address 0xd00 out of range [ 13.565] (EE) fglrx(0): Failed to obtain VBIOS from Kernel!

  • Xubuntu: Disks utility (palimpsest) and Gparted not showing up anywhere after installation

    - by Noam Gagliardi
    So I've downloaded Gparted and Disks from the software center. According to software center, they've both installed successfully... but they're nowhere to be found. Even in my terminal: $ palimpsest palimpsest: command not found I've looked in usr/bin... no "palimpsest", no "gnome-disk-utility". In usr/share/gnome-disk-utility there's a bunch of .ui files. According to Software Center, both programs are now installed in my computer, but it seems I've no way to find them. I've tried re-installing and restarting. I'm on Xubuntu 32 bit.

  • Handle php out of memory error

    - by PeterMmm
    I have a Drupal based web site on a relative small vserver (512MB RAM). Recently the website begins to return php out of memory messages like this: Fatal error: Out of memory (allocated 17039360) (tried to allocate 77824 bytes) in /home/... All php.ini memory limit parameters are set to off (-1). Propably the website has gained of complexity, content, etc. But I cannot interpret fine that message: Does that mean that the whole request has allocated 17MB(?) right now and cannot get 7MB(?) more from the OS. Has the web server spend all memory or has the OS no more memory to allocate ? I'm not shure if the memory overhead is coming from the web server or another service, because when I get the out-of-memoy message I can't get into the server with ssh. After a while all runs fine again.

  • Alternatives to PHP [closed]

    - by kaz
    We are starting a project, which goal is to create new frontend interface to our product. Old version was created in PHP, very poorly written. We are choosing the language and frameworks that we want to use in new version. Requirements: New interface will be communicating with API. Application will not have it's own database. We don't have a big team, 3 max programmers for entire project. The main programmers are PHP veterans and knows some other technologies (Rails, C, C++, some Java) but not in professional level. But overall they are good and experienced programmers. So: We want to find a good alternative to PHP. I like Rails very much, but whole ActiveRecord model will be useless, when using application API. Java needs a lot of configuration and someone who is expert in Java to properly run this project. Also, in Java there are a lot of big and complicated enterprise frameworks - not very good for 2-3 programmers team. Python - I don't know Python and don't know good and experienced programmers who knows PY - but it's not so complicated and big as Java and maybe in long period it's good alternative for PHP. What are your thoughts?

  • help me being the next zuckerberg [closed]

    - by Kraken
    I really expect someone to help me with my problem as stated below. I started learning website making by having tutorials from w3schools.com but after doing taking the HTML tutorials I don't think I really can do anything with it. Maybe I don't know everything about HTML yet. I know the online tutorials are not enough but what I need you guys to tell me is that how can I learn making some nice websites. I have vacations for two months now and I think it would be the best time for me to learn making websites as I really love to be a website developer. Now I would like to start from the scratch. I know some C language (though I know it will not help me). So tell me from where shall I learn HTML and what all things shall I learn after that and in what order. If you can also help me with the material (let it be books or online tutorials). But I would like to know how can I gain confidence that I can make some websites as just learning online tutorials doesn't help me much. I also tried some video tutorials but in that too, they will just tell me some of the functions and not all. So what am I supposed to do.. just know a limited functions as they want me to know in video tutorials or do something else.

  • Relative Positions Of Player And Enemy Are Different In XNA 3D Game

    - by CoOlDud3
    I am having a problem in my 3D Jet Fighter Game using XNA. I have a Player Jet and a few enemy drones built from a separate class. The problem is that when I set Player position and a drone's position to a height 10f in y direction. They aren't at the same height. But if i move Drone's Position up 500f in the y direction then it is pretty much close to the player. Relatively They are supposedly at the same height but with different position values. Can Any One Help Please?

  • FBO rendering different result between Glaxay S2 and S3

    - by BruceJones
    I'm working on a pong game and have recently set up FBO rendering so that I can apply some post-processing shaders. This proceeds as so: Bind texture A to framebuffer Draw balls Bind texture B to framebuffer Draw texture A using fade shader on fullscreen quad Bind screen to framebuffer Draw texture B using normal textured quad shader Neither texture A or B are cleared at any point, this way the balls leave trails on screen, see below for the fade shader. Fade Shader private final String fragmentShaderCode = "precision highp float;" + "uniform sampler2D u_Texture;" + "varying vec2 v_TexCoordinate;" + "vec4 color;" + "void main(void)" + "{" + " color = texture2D(u_Texture, v_TexCoordinate);" + " color.a *= 0.8;" + " gl_FragColor = color;" + "}"; This works fine with the Samsung Galaxy S3/ Note2, but cause a strange effect doesnt work on Galaxy S2 or Note1. See pictures: Galaxy S3/Note2 Galaxy S3/Note2 Galaxy S2/Note Galaxy S2/Note Can anyone explain the difference?
