• I want to master ASP.NET - What concepts should I focus on/What concepts do you most value?

  - by Josh

  I start a job this summer doing work in ASP.NET 4 (C#). I plan on working with some legacy code as well as MVC. I want to get a running start. I have good understanding of HTML/CSS/Javascript, and pretty good understanding of C# itself, Design principles, Design Patterns, and understand masterpages, basic MVC2, and code behinds for web forms. In your opinion what aspects of ASP.NET are the most important to master for web applications? What do you value most in your usage of ASP.NET? Do you have a recommendation for understanding the internals of ASP.NET itself?

• Smartassembly 5: it lives! Early Access builds now available

  - by Bart Read

  I'm pleased to announce that, late last week, we put out the first early access build for Smartassembly 5, Red Gate's fantastic code protection and error reporting tool, which we acquired last September. You can download it via: http://www.red-gate.com/messageboard/viewforum.php?f=116 It's obviously pretty early days, so please do not try to use this to protect a production application, but we've already done a lot of work in some key areas: We're simplifying and streamlining the licensing model (you won't see this yet, but a lot of the work on this has already been done). We've improved usability of the product, with a better menu, reordering of project settings, and better defaults. We've also fixed a load of bugs, which I'll let Alex blog about in more detail. On a slightly more trivial level, the curly braces are also no more. Over the coming weeks, we'll be adding more improvements, and starting usability tests. If you're interested in getting involved in the latter, please drop an email to [email protected].

• Web technologies on GUI apps

  - by Apalala

  I developed many GUI applications for the Windows platform during my early professional career, and saw several GUI frameworks come, have whole magazines devoted to them, and then fade away. MFC is iconic. Tasked with writing yet another GUI application, I starter researching cross-platform frameworks like Qt and WxWindows. I found the same steep learning curves I knew from before, and tooling doesn't help much in building a functional and elegant user interface because its clumsy and complicated. But people are building beautiful and functional UIs on the Web all the time (look at this site!). The standards, the libraries, and the tools are certainly there. My thought and my question: Why not write a GUI in which most of the UI is handled by an embedded browser? I already know that the Qt widgets support a large part of CSS and JavaScript, and programmers with good knowledge about web development are relatively easy to find, ..., so... Have you done something like that before? What's your experience/advise?

• How do I install Ubuntu on an iMac 27"?

  - by jml

  I have a beautiful 27" iMac. I would like to run Ubuntu on it natively, dual-booting with OS X. I have rEFIt installed, and I can boot into the Ubuntu 10.10 CD, kind of. Here's what happens: I select the CD from the rEFIt menu It loads for a while, then flashes up an aubergine screen with a very low-res picture of a human, an arrow and a keyboard It sits there for a while It changes to 80x25 console mode The screen then goes black, as if nothing is displaying to it All the while, the CD is churning away as if something is reading from it. What do I do?

• What do you need to know to get a job as a web developer

  - by Alex Foster

  What do you need to know to at the very least get your foot in the door? We're assuming for someone who doesn't have a college degree (yet) but will eventually get one. My guess is html, css, javascript, and php, and photoshop and dreamweaver, and sql. And being familiar with using a web host to have sites live, like knowing how to use cpanel. It's probably a very inaccurate and narrow guess but that's what i think right now. I don't know exactly.

• How can I change the wallpaper using a Python script?

  - by furtelwart

  I want to change my wallpaper in Ubuntu 11.10 (with Unity) in a small Python script. I found the possibility to change it via the gconf-editor in /desktop/gnome/background/picture_filename. With python-gconf, I'm able to change the necessary values. Apparently, the gconf string is not read out. If I change it (either via a script or via gconf-editor), the wallpaper remains and in the menu of "Change wallpaper", the old wallpaper is shown. How am I able to change the wallpaper for Unity via a Python script? The following code does work. Apparently, the gsettings are only applied, if some Gtk code is executed. #!/usr/bin/python # -*- coding: utf-8 -*- from gi.repository import Gtk, Gio class BackgroundChanger(): SCHEMA = 'org.gnome.desktop.background' KEY = 'picture-uri' def change_background(self, filename): gsettings = Gio.Settings.new(self.SCHEMA) print(gsettings.get_string(self.KEY)) print(gsettings.set_string(self.KEY, "file://" + filename)) Gtk.Window() print(gsettings.get_string(self.KEY)) if __name__ == "__main__": BackgroundChanger().change_background("/home/user/existing.jpg")

• How can I tell how a panel item was set up

  - by 4dummies

  I need to do some major surgery on a user account that has somehow sustained configuration damage to the point window decorations are gone, some apps don't listen to the keyboard, etc etc. I run xfce4 sessions. There's a panel on the top of the screen that has applications that I put there once upon a time. I know how to do that, sort of. But I don't remember the details of what I specified. And I'm unaware of an app for the panel that's like the menu editor that lets you see and manipulate an item that's already there. I want to do that because I want to re-do this stuff in a different account. Or possibly do a dotfile transplant on this account and re-edit to include the stuff I'm used to.

• How to Forward Local Drives to Remote Machines Using Remote Desktop

  - by Taylor Gibb

  Have you ever had a file on a flash drive that you needed to use on a machine that is situated in another building or even halfway across the world? You can do that by plugging it into your local machine and then forwarding the drive through your remote session to that machine. Here’s how to do it. Press the Windows Key and R to bring up a run box, and type mstsc to launch the Remote Desktop Connection Dialog, or you can just search for Remote Desktop in the Start Menu.

• Where to draw the line between front end and back end

  - by Twincascos

  I was recently contracted to develop a smarty theme for an automated SOHO phone answering service. The team who had built the backend wouldn't allow me access to any of the back end nor tell me anything about it, their smarty set up, smarty plugins, data base interface api, server set-up, nothing. Nor could I have access to the server nor a beta domain, basically zero co-operation. So I set up a local server with Smarty and built the template based on what I guessed would be their best practice, commented my code like crazy, wrote all the needed javascript, css, and template files. Then I sent them packaged to the backend team and hoped for the best. With half of a project team failing to cooperate or even communicate I am now concerned that they may reply saying that everything is wrong and they may refuse to implement the new front end. I'm curious to know if others encounter this type of situation and what you may have done to protect yourselves.

• One of my user accounts logs in without desktop environment

  - by Bill Cheatham

  When I log in to my main user account on Ubuntu 11.10 ,the desktop environment (unity bar, clock, volume control, etc.) is not there. All I have is the desktop background with a menu bar across the top which appears to be for nautilus (options like File-New folder). My other accounts log in like normal. I have recently followed these instructions to give my main user account access to an OSX partition, but I think I have logged in successfully since then. I am able to get a terminal by pressing ctrl+alt+t, but when I typed unity the whole thing crashed. Is there anything I can do to fix this? I have a separate administrator account I can use if needed.

• What is the best way to pass data into an API from a website?

  - by Chris Wakoksi

  My main objective is to create a User Interface in order to provision(change the status: activate, deactivate, or suspend) modems. I have received a SOAP developer's guide to the specific type of modem that helps out with the specific values that I need to pass into Iridium's WSDL but I cannot figure out how to do this from a webpage I have created using HTML/CSS, and PHP? I have been told by others that I need to know the portal. I have no idea what that means. I am a beginner programmer who has learned programming for this project. Any suggestions as to how to pass my data into the provisioning API?

• Ethernet on an Acer Aspire One D255E not working

  - by Dustin

  Ok very frustrated here, but hopefully can find an answer here. I have an Acer Aspire One netbook D255E. I installed 10.04 desktop edition via live USB, only to find out ethernet is not connecting. The thing is, I had installed previously 10.04 thru wubi as 30GB, but wanted more so did this install. With the Wubi install it worked great internet worked added LibO, mint menu ect. So I know it could work, and it works on Win 7(what little GB is left). I have ethernet enabled, and gave myself all permissions, but still not working. Thank you for any help, and if you do more details in the steps i need to take the better :).

• Tomboy won't start

  - by torbengb

  I've just discovered Tomboy and like it. I added it to the startup applications, and on next boot Tomboy won't start. It then also won't start when I select it manually from the menu. I unchecked its entry in the startup applications and rebooted, but it still won't start. I uninstalled it and installed it again in order to perhaps fix some broken file or setting, but it didn't help. I saw this question and added the Applet. But the applet says "Tomboy Notes" has quit unexpectedly and a reload doesn't work; the message appears again. How can I determine (and fix!) what's wrong?

• Decrease mouse sensitivity below the standard limit.

  - by Bruce Connor

  I've got a USB mouse attached to my Ubuntu notebook. This mouse is (unfortunately) really sensitive, and so it sometimes gets hard to hit small icons with the mouse pointer. This is really a hardware issue, it's not a bug and it's not Ubuntu's/gnome's fault. Still, I would very much like to this issue through software (solving through hardware would imply buying a new mouse). Back in Windows, if I set the sensitivity as really low it was comfortable enough. In Ubuntu, even the lowest sensitivity and acceleration available (in the SystemPrerencesMouse menu) is still frustrating. How can I decrease it below the default minimum? I tried xset, but it seems xset only deals with acceleration and threshold, but not actual sensitivity.

• Oversizing images to produce better looking pages?

  - by Joannes Vermorel

  In the past, improper image resizing used to be a big no-no of web design (not mentioning improper compression format). Hence, for years I have been sticking to the policy where images (PNG or JPG) are resized on the server to match the resolution pixel-wise they will have with the rendered page. Now, recently, I hastily designed a HTML draft with oversized images, using inline CSS style such as width:123px and height:123px to resize the images. To my (slight) surprise, the page turned out to look much better that way. Indeed, with better screen resolution, some people (like me), tend to browse with some level of zoom (aka 125% or even 150% zoom), otherwise fonts are just too small on-screen. Then, if the image is strictly sized, the enlarged image appears blurry (pixel interpolation effect), but if the image is oversized the results is much better. Obviously, oversizing images is not an acceptable pattern if your website is intended for mobile browsing, but is there case where it would be considered as acceptable? Especially if the extra page weight is small anyway.

• Question about JPanel "transition" for Java Swing

  - by user16778

  I want to make like a sort of main menu (in GUI). When the user clicks the start button, the screen transition into another "screen" (JPanel). This image will make it easier to understand. http://i.imgur.com/Cfdry.png Currently, I have a MainMenu extends JPanel and that gets added into a driver class with a JFrame. I can't figure how to switch to another class like Game extends JPanel. So when the user clicks the start button in MainMenu, I want it to somehow hide itself and the Game to show itself. Thanks.

• What is the best way to become a professional in PHP and Website Building?

  - by Mr.TAMER

  I would like to become a professional in php, I have learned nearly all about the language syntax and concepts and I have a good knowledge in C and C++, which made it easier to become familiar with PHP. (Of course, I learned MySql too.) But I don't feel like being able to build even a little good website of my own! It looks like PHP is all about knowing lots of functions and using them, while in fact I don't think it's like that, is it? How can I become a professional in PHP and Website Building? I would do anything and spend whatever amount of time required for that. EDIT I've also a very good knowledge in HTML and a normal knowledge in CSS and JavaScript. Sorry for not mentioning that, I just thought it was implicitly included.

• Pay for Graphic Designer vs Programmer

  - by FrankSinatra

  In a corporate web-design setup, who typically makes more per hour, the graphic designer or the programmer? By graphic designer, I mean somebody who builds mockups probably in photoshop, selects font-styles, colors, etc. Most things layout-wise are near pixel-perfect, but likely after the initial implementation by the programmer, there will be a lot of small changes directed by the graphic designer. By programmer, I mean somebody who is coding the CSS, the HTML, and light backend support, probably in PHP. The programmer will attempt to duplicate the mockups given the limitations of the medium, and consult with the graphic designer afterwards on what changes are tangible and which are not. Both probably have an undergraduate degree from a respected four-year institution.

• Can't disable giant cursors (from accessibility mode)

  - by jackweirdy

  I've just installed ubuntu 12.04 from a livecd. Out of curiosity, I enabled the accessibility options for people who are hard of sight. As you can guess this does the usual stuff of inverting colours, increasing text size and making the cursor larger. Having finished the installation I booted into the new system to find accessibility mode was still installed. From the lightdm login screen I disabled this which switched colours and text size back to default, however it's only the pointer cursor that has gone back to default. To put it another way, the "hand" icon that you get when hovering over a link, the cursor which appears when typing and pretty much every other cursor on the system are still large. I've looked on the Universal Access menu, but there's no option to disable large cursors. I've tried toggling accessibility on and off but to no avail.

• Ubuntu 13.04 on UEFI system with Windows Boot Manager as the main loader

  - by Mehrdad

  On my old laptop (legacy BIOS, MBR disk), this was perfectly possible to get working: I turn on the computer and see the Windows Boot Manager I use EasyBCD (or BootPart, or something else) to add an option to the BCD menu which allows me to boot into GRUB, and then into Ubuntu I can't figure how to do this on my new laptop (UEFI, GPT disk), whether in UEFI or legacy mode. Currently I've installed (and even booted!) Ubuntu on my laptop, but only with the help of an external GRUB (on a USB flash drive). How can I add GRUB as an option in the Windows Boot Manager on a UEFI laptop? (No, I don't want to change my primary boot loader. So no, I don't want to overwrite the Windows boot loader with GRUB.)

• SOA Suite 11g (11.1.1.3): Creating a single server domain with SOA Suite and Oracle Service Bus func

  - by Chris Tomkins

  One of the major benefits of the latest version of the Oracle SOA products, SOA Suite 11gR1 PS2 (11.1.1.3) and Oracle Service Bus 11gR1 (11.1.1.3), is that both products depend on the same version of WebLogic Server 11g (10.3.3) and so can be installed in the same domain. If you are a developer building artifacts for both but with a laptop/desktop with limited resources then this is particularly useful, as you can install a single server domain (by default you get a domain with an admin server and multiple managed servers) which incorporates both sets of functionality. The viewlet below shows you how to go about creating such a single server domain, using the configuration wizard. Just click the Play button from the viewlet menu to start it. Note: As you have added all this functionality into a single server, it will take a few minutes to start up. As this is my first foray into the world of viewlets I’d be interested in your opinion as to whether you have found this useful and any tips/techniques for improving any future viewlets I may create.

• What is the typical example of old school website design?

  - by Pierre 303

  I want to build a website for a retro thing that was popular in the mid 90s (beginning of the commercial internet). So I want use old designs that was very popular at that time. The first thing that comes to my mind was those "under construction" animated gifs. People often put animated gifs everywhere. But also those awful repeating backgrounds. So yes, I want my website to look exactly like in the mid nineties ;) (please suggest practical and usable features, I guess an Java Applet menu would not work today, or saying on the bottom that this website is optimized for Netscape 3) EDIT: for those that wants to see the result: Retrology

• Does dist-upgrade require PPA software to be uninstalled first?

  - by seb

  Hi all, I'm still running Ubuntu 10.04 with quite a few PPAs. Amongst the PPAs there is Guiodic (Guido Iodice) Lucid quasi-rolling :) PPA which brings most recent versions of many programs to my desktop. My steps: sudo update-manager -d click on upgrade on the appearing window wait for the magic to happen: prepare to upgrade and setting new software channels during 'calculating the changes' I will get the following error message in the panel An error occurred, please run Package Manager form the right-click menu or apt-get in a terminal to see what is wrong. The error message was: ' Error: Marking the upgrade (E:Error, pkgProblemResolver::Resolver generated breaks, this may be caused by help packages.)'This usually means that your installed packages have unmet dependencies When I check Synaptic/apt-get I can't find any errors or hint toward broken packages Could this error be because of many PPA versions being newer than 10.04 original versions?
