  • c# class naming standards/guidelines

    - by Ben
    Over the years I've used various naming conventions for services in my applications for example: [ClassName]Service [ClassName]Manager [ClassName]Factory [ClassName]Provider [ClassName]Helper I generally only use the "Helper" suffix for utility classes that have no external dependencies. However I find that there is a bit of a cross-over between the others, and wondered if there was any recommendations/standards/guidelines on what to use and when?

  • Install PHP on RedHat

    - by John R
    I just ran yum install php in the command prompt. Everything went fine ('complete!') as per the dialogue. I then uploaded a file that does not use short tags and is named with the proper extension (i.e., the name is test.php). <?php print "hello world"; ?> When I navigate my browser to test.php it just prints each of the characters shown above; i.e., PHP is not interpreting it. What might be the problem? Also, if there is a configuration file that needs to be updated, please tell me what directory path I am likely to find that file. Edit: Apache2 & Redhat

  • Justification for learning/implementing newer Microsoft technologies

    - by Darren
    I work at a large healthcare organization as a mid-level software developer. I have over 10 years experience in the IT industry using Microsoft technologies (ASP.NET & SQL Server). When I go to conferences, code camps, .net user group meetings, I hear of all kinds of new tools and technologies: MVC, LINQ, Entity Framework, WCF Web Services, etc. I guess you could say I'm in my comfort zone using the same old stuff from asp.net 2.0. I use typed datasets for my data access layer. I use web forms and feature rich server controls with master pages. I know how to use plain old SQL and create queries in my typed datasets to get at data my applications need. Throughout my career, I'm always sensitive to not become obsolete with my skill set. What I currently use works fine and my development time is fast. But I'm concerned that if I were to be laid off, I would be asked in interviews how many MVC apps I've written. Or how I am with LINQ or WCF web services. I know that it doesn't matter how many conferences, books, or videos I watch on some new technology...I have to implement/use it or it simply won't sink in. Also, managers who interview don't care how much someone reads up on something, only real use and experience with a technology. I have a new project to write. I've gone to my manager and have asked for additional time for the project for learning/implementing technology I may not be familiar with. Our organization encourages its employees to "learn and grow" and to continue are education. But I always get resistance when I ask for more time to ramp up on something new to implement. My manager is asking for concrete business reasons for implementing these new technologies. I don't have business reasons. My reasons are because I don't want to become obsolete. I could say it would make the project more maintainable in the future by other developers since at some point people could stop using these older technologies, but that' about all I can think of. Does Linq/Entity Framework/MCV apps perform better? So much so that the customers (users in departments I'm creating this app for) need? I doubt it. I'm interested in you guy's thoughts on this. Do many of you have similar plights with trying to use newer upcoming technologies? I doubt I'm on the bleeding edge of technology, either. Are there "business reasons" that you would bring to light for using these technologies? Thanks in advance! Sorry for the long wall of text.

  • How do I fix the problems I'm having with Xfce and Xubuntu?

    - by Noel Quiles
    I booted into a Xubuntu session and when the splash disappeared it left behind artifacts on the desktop. I went into Desktop to change the background but it stayed completely gray. Not only that, GTK isn't theming any of my windows, nor can I change GTK themes in the settings manager. I recently installed GTK+ 2.x alongside GTK+ 3 for a compatibility issue with xfce-battery-plugin, which also refuses to show anything but 0%. What is going on?

  • Space a valid delimiter for email addresses in email header?

    - by semanticalo
    Is it syntactically correct to delimit multiple email recipients in the "To" header of an email with spaces only or do I need to use another delimiter (a semicolon or the like)? Example (MIME data reads as follows): Date: Mon, 04 Oct 2010 06:14:16 +0200 From: [email protected] To: [email protected] [email protected] [email protected] Subject: Test Subject The above will be processed by many email processing applications, but I need to know whether it's correct according to standard (RFC). Unfortunately I didn't find anything useful on the internet so far. Thanks a million for your help!

  • Camera field of view: 3D projections & trigonometry

    - by Thomas O
    Okay, here goes. I have a camera at (Xc, Yc, Zc.) The Xc and Yc coordinates are latitude/longitude, and the Zc coordinate is an altitude in metres. I have a point at (Xp, Yp, Zp) and a field of view on the camera (Th1, Th2) - where Th1 is horizontal FOV and Th2 is vertical FOV. Given this information, I'd like to: test if the point is visible (i.e. in the camera's FOV) project the point as the camera would see it I've figured out already that the camera's horizontal view at any given distance is tan(Th1) * distance, but I don't know how to test if the point is visible. Accuracy is not critical. I would prefer a simple solution over a complicated solution, if it works well enough. The computations will be performed by a small microcontroller, which isn't very fast at things like trig functions. P.S. this is not homework, I'm doing this for some game development. It will be integrated with the real world, hence the latitude/longitude/altitude. It involves flying real RC planes through virtual hoops (or chasing virtual targets), so I have to project the positions of these hoops on a display.

  • How to lock screen in linux before hibernating?

    - by Emanuel Ey
    So when i hibernate my laptop the screen doesn't lock automatically. To solve this i've changed /etc/acpi/powerbtn.sh to contain: su - myUsername -c "gnome-screensaver-command -l" sudo pm-hibernate exit 0 When running this file from a command line it works as intended (ie, lock the screen and then hibernate). Unfortunately, when pressing the power button, it still just hibernates without locking the screen -what am I missing? EDIT: I've added the line whoami>>~/Desktop/test.txt to verify which user is executing the /etc/acpi/powerbtn.shscript. When pressing the power button, the file test.txt is created, but is empty. From this i conclude that the script is in fact being called when pressing the power button. What i do not understand is how the output of whoami can be empty...

  • Disable comments / Spam protection

    - by SamIAm
    My client site is built in Silverstripe, there is a news page, and it allows people to leave comments. Unfortunately we've got loads of spam emails. I'm new to this, is there any way we can disable the comment field by default? How do I do it? Alternatively is there easy way for me to install a spam protection? Thanks heaps. Sam Update - Because this is someone else's code, I just realised that they have some sort of spam protection already, so we are trying to disable comments now. I have manage to set no comment as default by changing file BlogEntry.php static $defaults = array( "ProvideComments" => true, 'ShowInMenus' => false ); to static $defaults = array( "ProvideComments" => false, //changed 'ShowInMenus' => false ); Am I on the right track to disable comments by default? Also how can I stop on the news page showing xxx comments link? eg Test Posted by Admin on 21 June 2011 | 3 Comments Tags: P This is a test.... 3 comments | Read the full post Thanks. S:)

  • HTTP downloads slow - FTP of same file very fast - Windows 2003

    - by Paul Hinett
    I am having some issues with download speeds on my site via http, i am averaging around 70kbps downloading a file that is around 70mb. But if i connect to my server via FTP and download the same file on the same computer / connection i am averaging about 300+kbps. I know my server has alot of connections at any one time, probably around 400 connections. My server has a 1gbps connection to the internet so there is plenty of bandwidth available, as proven with the FTP. I have no throttling of any kind enabled in IIS. If interested there is a test file here you can download to check the speed: http://filesd.house-mixes.com/test.zip I am based in the UK and the server is in Washington, USA if that makes any difference.

  • Logitech USB headset not working on 12.04

    - by thepeoplescoder
    I've looked around for answers to this question, But none of them seem to work for my particular problem. Obviously my USB headset isn't working, But I might as well share the scenario. I am running Ubuntu 12.04 and I have a Logitech USB headset. The relevant output from dmesg is as follows: [160708.528047] usb 2-1.2: USB disconnect, device number 9 [160768.890123] usb 2-1.2: new full-speed USB device number 10 using ehci_hcd [160768.997578] input: Logitech Logitech USB Headset as /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.3/input/input15 [160768.997795] generic-usb 0003:046D:0A0C.0005: input,hidraw0: USB HID v1.00 Device [Logitech Logitech USB Headset] on usb-0000:00:1d.0-1.2/input3 When I go to System Settings - Sound, My headset shows up in both the Output and Input tabs, It is called "Clear Chat Comfort USB Headset" in those tabs, But I doubt that's a serious issue. When I click my headset in either tab to use it, The changes are not remembered when I reopen the sound settings, the built-in audio is still used. Also when I select the headset in the Output tab, and click the Test Sound button to test everything, The sound still comes from my laptop's onboard audio, instead of from my USB headset. Does anyone know how to correct this? I am stumped.

  • BizTalk 2009 - The Community ODBC Adapter: Receive Location

    - by Stuart Brierley
    I have previously talked about the installation of the Community ODBC adapter and also using the ODBC adapter to generate schemas.  But what about creating a receive location? An ODBC receive location will periodically poll the configured database using the stored procedure or SQL string defined in your request schema. If you need to, begin by adding a new receive port to your BizTalk configuration. Create a new receive location and select to use the ODBC adapter and click Address. You will now be shown the ODBC Community Adapter Transport properties window.  Select connection string and you will be shown the Choose data Source window.  If you have already created the Test Database source when generating a schema from ODBC this will be shown (if not go and take a look in my previous post to see how this is done).   You will then need to choose the SQL command that will be run by the recieve port.  In this case I have deployed the Test Mapping schemas that I created previously and selected the Request schema. You should now have populated the appropriate properties for the ODBC Com Adapter. Finally set the standard receive location properties and your ODBC receive location is now ready.

  • Problem installing UniversalIndentGUI

    - by DNikolov
    I need a GUI beautifier for C code. I've found UniversalIndentGUI on sourceforge. Downloaded a .deb file.Opened it with Ubuntu Software Center to install it but the button is grey and unclickable and there is a line saying Dependency is not satisfiable: libqscintilla2-3. I've installed via the Synaptic Package Manager libqscintilla2-5 but that didn't help. Is there any way to install the UniversalIndentGUI, the libqscintilla2-3 package or to some how work around the problem?

  • GUI keyword confusion

    - by richzilla
    Ive been using linux for some time, and ive never quite got my head around the various keywords attached to the GUI. I think i understand the difference between the likes of KDE and Gnome - They are collections of applications and other software that make up a given gui environment. However a quick read through any vaguely technical linux websites will reveal terms like: Murrine Clearlooks GTK Beryl Metacity Window manager Which if im honest, i have no real idea what they mean and how they all relate to each other. Can anybody clarify?

  • Wireless internet connection connects but internet does not work (no packets received). Wired does.

    - by Rodney
    When I connect my PC via ethernet cable to my ADSL router it works fine. When I connect via Wireless it connects and the internet will work for a random amount of time and then stop working. It stays connected with a strong signal but no packets are received. My laptop/iphone are right next to it and wireless works fine. If I open the Wireless USB status, it says it is connected to my SSID with full strength (54 mps - I am 3 meteres away from my router) and the activty shows as Packets 594 SENT and 105 RECEIVED (this goes up VERY slowly) I have tried the following: Turned off anitvirus and firewall completely. Tested the wifi signal- I am writing this on my laptop which is next to my PC and also has full wifi strength. Tried a different wireless adapter - I dug out an old PCI wireless card - it does the exact same thing. Compared all wireless settings to my laptop. I can ping google.com and it replies (sometimes with packet loss) When I reboot the PC it will connect for a minute or two (random time) and then just stops again. I tried Firefox, IE etc. no joy I have updated all latest versions (Netgear WG111v2) and drivers Checked Event Log - nothing unusual Ping the router (and even connect as admin for the few minutes when the internet does work) Changed the MTU down to 1200 using DrTCP Checked Device Manager for conflicts - none. I ping the router from the PC (192.168.0.10 - 192.168.0.1) and it replies with 4 packets. BUT, on my router admin page (which I access via http on my laptop wirelessly) - if I ping 192.168.0.10 all packets timeout (pinging my laptop 192.168.0.12 works fine) My router admin page shows the leased IP address for 192.168.0.10 (ie it is definitely talking to the router initially) Now I am out of ideas - please help. I think it is an OS/Software issue as I have tried 2 different wireless adapaters (PCI and USB) with the same result but all other wireless devices work fine around mine). It's not the firewall. It is getting assigned an IP address correctly (my PC gets 192.168.0.10, my laptop is .12) It is assigned by DHCP. As soon as I plug in the ethernet cable it all works fine. Repairing the adapter sometimes helps but it will always stop working after a random time. The wireless adapter always shows as connected with Excellent signal but the internet does not work. I am running Windows XP SP3 and have tried a Netgear WG111v2 USB adapter. Thanks in advance! UPDATE: The internet seems to be working, it is just either sending packets too small or slow to work (some small pages load bits of them very slowly but then hang). XP seems to have a networking diagnostic app - here is the output: Last diagnostic run time: 08/30/10 08:16:38 IP Configuration Diagnostic Invalid IP address info Valid IP address detected: 192.168.0.10 IP Layer Diagnostic Corrupted IP routing table info The default route is valid info The loopback route is valid info The local host route is valid info The local subnet route is valid Invalid ARP cache entries action The ARP cache has been flushed Gateway Diagnostic Gateway info The following proxy configuration is being used by IE: Automatically Detect Settings:Disabled Automatic Configuration Script: Proxy Server: Proxy Bypass list: info This computer has the following default gateway entry(ies): 192.168.0.1 info This computer has the following IP address(es): 192.168.0.10 info The default gateway is in the same subnet as this computer info The default gateway entry is a valid unicast address info The default gateway address was resolved via ARP in 1 try(ies) info The default gateway was reached via ICMP Ping in 1 try(ies) info TCP port 80 on host 65.55.12.249 was successfully reached info The Internet host www.microsoft.com was successfully reached info The default gateway is OK DNS Client Diagnostic DNS - Not a home user scenario info Using Web Proxy: no info Resolving name ok for (www.microsoft.com): yes No DNS servers DNS failure HTTP, HTTPS, FTP Diagnostic HTTP, HTTPS, FTP connectivity info FTP (Passive): Successfully connected to ftp.microsoft.com. info HTTP: Successfully connected to www.microsoft.com. warn HTTPS: Error 12002 connecting to www.microsoft.com: The operation timed out warn HTTPS: Error 12002 connecting to www.passport.net: The operation timed out error Could not make an HTTPS connection. info Redirecting user to support call WinSock Diagnostic WinSock status info All base service provider entries are present in the Winsock catalog. info The Winsock Service provider chains are valid. info Provider entry MSAFD Tcpip [TCP/IP] passed the loopback communication test. info Provider entry MSAFD Tcpip [UDP/IP] passed the loopback communication test. info Provider entry RSVP UDP Service Provider passed the loopback communication test. info Provider entry RSVP TCP Service Provider passed the loopback communication test. info Connectivity is valid for all Winsock service providers.

  • Game window systems and internal frames

    I don't know if this is a valid question, but: What kind of window manager do games use which have internal frames (Frames inside frames)? Does this differ between the programming languages (Are e.g. in Java the AWT/Swing libraries used to manage these and other graphical elements, such as buttons,or is this to restrictive (speed, graphical possibilities?)) A special example would be EVE Online, where the client can use the ingame windows like on a normal desktop.

  • Can't fix broken packages

    - by AWE
    I am too dumb but determined to use Ubuntu that I paid a professional to install it for me (dualboot 11.10 with Win7). When I came home I got a lot of things from the software center. Skype did not have a download button so I googled it and Ubuntu help told me to do this: sudo add-apt-repository "deb http://archive.canonical.com/ $(lsb_release -sc) partner" and then this: sudo apt-get update && sudo apt-get install skype The terminal told me "that this is potentially harmful..." but I thought it was Ubuntu language meaning "are you sure?" Now the computer is mute. Items cannot be installed or removed until the package catalog is repaired, so I want to repair it but the package operation fails. "sudo aptitude -f install" - command not found Synaptic package manager tells me that I have two broken packages, libc6 and libc6-dev so I do this: sudo apt-get update && sudo apt-get upgrade which tells me to do this: sudo apt-get -f install that ends up like this: Can't exec "locale": No such file or directory at /usr/share/perl5/Debconf/Encoding.pm line 16.

  • Blank screen after Switch User or Resume

    - by matt wilkie
    About half the time when I switch users or resume from standby or resume the screen goes blank (black). If I work the cursor keys I can hear the system bell when it gets to the end of the user list. I can also successfully login, going from memory, but screen stays black. Sometimes closing and re-opening the lid will light up the screen again. Pressing the special Function key to enable/disable external monitor connection has no effect [Fn]-[F5],[Fn]-[F6]. If none of the previous work I need to put the computer into hibernation or full power off to restore screen function. If I watch closely when switching users I think I can see the screen initially start to light up and then quickly fade to black. The computer is an Acer Aspire 3500, model ZL6, running Ubuntu 10.10 installed 2 days ago. No proprietary drivers are in use. I'll provide a list of hardware details as soon as I can figure out how to generate that (didn't there used to be an entry for hardware details under the System menu?). Possibly related questions: No resume after Hibernate or Standby When I resume from suspension - the screen is blank Switch user fails to complete successfully For what it's worth, blank after resume also used to happen occasionally when the laptop was running XP-Home, but nowhere near as often, perhaps 6 or 8 times a year. UPDATE: I found System Administration System Testing and ran the Monitor test. It went very very dark, but the window elements could be discerned, and the whole screen flashed (from very very dark to black). On the third repeat of that same test the screen went to full blaupck and stayed there. Moving the mouse, via touchpad, or touch keys did not wake it up again. I had to close the lid and put the computer into hibernate, and press the power button to restore it. UPDATE2: output of lshw: http://pastebin.com/q7n8676r, lspci: http://pastebin.com/6ujzVK4r UPDATE3: sometimes I can restore the screen by flipping to console 1 with ctrl-alt-F1 and then back to graphical with ctrl-alt-F7.
