• Why is Reflector such an essential utility?

  - by c152driver

  Reading the brouhaha surrounding Reflector going paid got me thinking about the product and its uses. Many people seem to consider it an essential tool. I have to admit, I haven't used Reflector in years. I mean, there's documentation for both the .Net APIs and the third party components I use. In the past, whenever a colleague pulled Reflector out of his tool belt, I got the sense he was headed into the weeds. Reading all the passion around Reflector is leading me to question if I'm really missing something here. Why do you need something like Reflector so often that you consider it an essential tool? I can see it being needed on very rare occasions, but not enough to be considered an essential tool. Please enlighten me.

• Inconsistencies in Health Monitoring Between WebForms and MVC

  As I have written and spoken on numerous occasions, Health Monitoring happens to be one of my favorite features in ASP.NET. In WebForms, it's a path well trodden. However, while building Morts & Elvises with MVC2, I ran into a strange inconsistency, which I'd like to describe here. WebForms Whenever a WebForm throws an unhandled exception, at the very least the error is written to the system's even log. Suppose we have this silly simple page method: protected override void OnLoad...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• Can't copy from hfs+ external

  - by Janine

  I've spent days and days trying to figure this out, but still can't. I think I've read every article on this and tried all there is to try, and I still can't copy any file from my mac-formatted hfs+ external drive. Sorry if there's still an article I've missed.. I have disabled journaling and tried all the hfsprogs commands I could find, but still whenever I click on a folder on the external and try to copy it to my home directory, I get this: "The folder xxx cannot be handled because you don't have permission to read its content." I then found an article about inoring this by copying files through the Terminal. When trying to run the sudo cp -r command in the Terminal with my external drive path, I always get 'no such file or directory'.. Does anyone have another suggestion for me? Thanks in advance!

• What does Avg Position from Google Webmaster really mean

  - by RandomBen

  I have a website I am tracking on Google's Webmaster tools. When I look at the Search queries page it shows me a graph of Impressions and clicks per day. Underneath that there is a table showing specific results. One of the columns is Avg Position. That columns seems to include paid ads. Is that correct, does the Avg Position also include the top result ads(the ads at the top of the search results)? I am asking because the company I work for has a not so common name and whenever I Google it our site is the #1 result 100% of the time. The only thing above it is 1 paid add. When I checkout Webmaster tools I notice that searching for our name returns with us at an Avg Position of 2.0. That seems like it would be only possible if paid top result ads were included in that position. Does anyone know?

• Coding style advice? [closed]

  - by user1064918

  I'm a newly grad. I've got a lot of complaints from my supervisor at work during code-review sessions with regard to my coding style (Surprise!). I don't know if it's just him being cranky or my style is really that annoying to read. I come from the low-level language world (assembly, mostly), so I've been taught to use bitwise ops and all the cool tricks to do math whenever possible. I also have the habits of doing some other things that've been regarded as "too excessively dense to read". So I'm hoping to get some feedback from any experienced programmers! :) Also how should I justify between code performance and readability? Thanks!!

• Unable to create xcode project again from unity

  - by Engr Anum

  I am using unity 4.5.3. I already created/built xcode project from unity. However, there were some strange linking errors I was unable to solve, so I decided to delete my xcode project and rebuilt it again from unity. Unfortunately, whenever I try to build the project, just empty project folder is created. There is nothing inside it. I don't know why it is happening. Please tell me how can I create xcode project again. May be I am missing small thing. Thanks.

• Choppy/unresponsive keyboard and mouse pointer until suspend

  - by Stefan Thyberg

  I had a problem where my mouse and keyboard would be choppy, the mouse pointer would work at 1-2 fps and the keyboard would keep missing letters as I was typing them. Since they were both USB I suspected there was a problem there immediately. Whenever I got this problem I would suspend the computer and start it again and the problem would be gone. The problem started appearing when I plugged the mouse and keyboard directly into the computer rather than the USB hub in the screen. I'm using a Logitech UltraX Flat and a Razer Lachesis, but I'm not sure if that matters.

• Weird XDG User Dir resetting bug

  - by sybreon

  I have a weird problem with 12.04 LTS. Regardless of what I do to the ~/.config/user-dirs.dirs file, whenever I login again the next time, that file gets all set to $HOME only. Something is happening during login using lightdm that overrides the contents of that file. If I login and do a xdg-user-dirs-update --force then the contents of the file are OK. After I logout, the file is still OK. It's when I login again using lightdm that something goes wrong. It's quite annoying.

• Cannot make wireless "forget" networks to which it cannot connect

  - by cboettig

  I see that I can delete networks that my machine "remembers" from nm-applet by clicking on the wireless icon in the panel and selecting "edit connections" - "wireless". However, sometimes I click on the wrong wireless connection by accident in the dropdown list. If the connection is secure, the machine of course never successfully connects, but somehow it still seems to memorize the ESSID. Whenever I'm in range of that wireless, it now tries to connect. Worse, if not connected to any other network, it repeatedly prompts me to connect to this network. If left unattended, I may find dozens of copies of the window prompting me to log in to this mistaken network. There must be a file somewhere that records this connection ID, but I cannot find it. The only connections appearing in the "edit connections" I mention above are those to which I've actually connected. How do I find the file and delete the line corresponding to the offending "memorized" network?

• How to prevent thunderbird gmail/IMAP from marking deleted/archived emails as read

  - by Jesse

  I have thunderbird setup to use gmail IMAP. I followed the various guides that recommend setting Edit-Account Settings-Server Settings-When I delete a message-Remove it immediately. Unfortunately this didn't have quite the effect I wanted and after more digging I discovered here that: [Thunderbird] [Gmail] Mark Deleted = Archive Copy to [Gmail]/Trash = Delete Permanently Remove it immediately = Archive Unfortunately whenever I deleted (archived) a message it was also marked as read whether it had been or not. I didn't want this because I like to keep my inbox clean and archive anything that doesn't actually matter, such as funny emails, etc. and then go back and look through the archive later when I have time. What settings do I need to prevent messages from being marked read when I delete them? I'm using Thunderbird 17.0 on Ubuntu 12.04

  - by ved2254

  I have an XPS15 laptop, core i5, 8GB ram. Whenever I login my laptop I here the startup bongo sound. But my sound system just doesn't play anything, may it be a short audio clip or a movie. Output of lshw -c multimedia is : WARNING: you should run this program as super-user. *-multimedia description: Audio device product: 6 Series/C200 Series Chipset Family High Definition Audio Controller vendor: Intel Corporation physical id: 1b bus info: pci@0000:00:1b.0 version: 05 width: 64 bits clock: 33MHz capabilities: bus_master cap_list configuration: driver=snd_hda_intel latency=0 resources: irq:51 memory:f1c00000-f1c03fff WARNING: output may be incomplete or inaccurate, you should run this program as super-user. Headphones work just fine but there is no sound from the speakers. Is it a bug in multi-media players or ALSA?

• Whats the thing the report bugs in php?

  - by Max Hazard

  Currently I am learning php. Php is understood by browser itself right from php sdk right? SDK include libraries right? So browser is like an interpreter of php codes. I want to know that whenever I type a wrong php syntax what is the thing report me the error? Obviously the browser is reporting the error. But what part of it? I mean I don't get it. Like writing a compiler we do lexical analysis and make the compiler which report any bug in source code. I assume here browser is analogous to compiler. I don't know exactly but compiler contains bug report functions or methods which is debugger. Debugger is part of compiler which report bugs. Does the browser contains such debuggers? Can there be any browser which doesn't understand php?

• When clicking below window title bar in KDE, window dragging is initiated. Can I change this behavior?

  - by hdpq

  this one is regarding KDE in Ubuntu 12.04. The thing is that whenever I click below the window title bar in KDE, the window manager always assumes I want to drag the window, not just activate it. Clicking the title bar activates the window without dragging it just fine, however I sometimes find it hard to click because it's rather narrow :) Is there any way to change this behavior (besides the obvious "make your title bar larger" thing)? I also assume this is happening to Gtk applications only (Firefox, Thunderbird, Synaptic), as I have tried it with several KDE apps (KWrite, KTorrent, Gwenview, Konsole) and noticed no such behavior. Thanks in advance!

• How to prevent Ubuntu from changing screen brightness?

  - by cholazer

  I have recently installed 12.04 on ASUS-K53SV-V300. I can change the brightness on start-up with: echo 0 > /sys/class/backlight/acpi_video0/brightness >> /etc/rc.local or manually by Fn key. But, whenever Ubuntu dim my screen brightness to save power or wake-up from suspend or inactive for 20-30 seconds, brightness reset to high (my problem get much more when on battery). How can I disable screen brightness service to prevent it from changing my brightness? What service work on screen brightness? If I disable this service, can I manually set brightness by command? I found a program to work on brightness instead of default power manager.

• Not able to suspend or hibernate

  - by Tim

  My Ubuntu 10.10 on my laptop Lenovo T400 is not able to suspend or hibernate. Whenever I click Suspend or Hibernate, the moon LED on the bottom of the lid flashes a few seconds, the screen quickly shows something like "some devices fail to suspend, error 5", and then the moon LED goes off and the display still has ambient light illumination. I suppose in suspend or hibernation state, the display should have no illumination, just like when the laptop is turned off, right? If I press any key, the unlock screen dialogue will pop out. I searched a little on the internet, and installed 'acpi-support' according to some advice but it does not help. Any suggestions to solve this problem? Thanks and regards!

• chrome download interrupted leaving ".crdownload" temporary file

  - by Tim

  I am using Google Chrome 15.0.874.121 in Ubuntu 10.10. It was fine until recently. Whenever download a file, it always reports "Interrupted", but it actually finishes the downloading, leaving an intermediate file with extension ".crdownload". If removed the extension, the file will be perfect. Note that downloading in Firefox works fine at the same time. So I wonder if it is a bug or how I can fix it? Thanks and regards!

• Git does not ask for passphrase during pull/push in terminal

  - by Damian

  I'm trying to use git from the terminal in my Ubuntu 12.04 desktop. My repository is hosted in Github, and I have the a key for my desktop. Whenever I do either "git pull" or "git push," a dialog box will pop up asking for my passphrase. This works fine if I type the passphrase correctly. However, if I'm connected to my desktop through ssh and do a git pull or push, the command does not prompt the passphrase and it outputs the following error: Permission denied (publickey). fatal: The remote end hung up unexpectedly This error makes sense because I'm not inputting my passphrase. So the question is, how can I get the passphrase prompted in the terminal? Thanks!

• Adding a value to a 'datetime' column caused overflow.

  - by sathya

  Adding a value to a 'datetime' column caused overflow. Came across this error today. So thought of posting the same. Whenever you try to do a dateadd like this  dateadd(mm,12,datefield) you might face this error if the value in your records in the datefield is not a valid date or if u add some months or date to this value and the output of that will exceed the date range In my case i was just thinking what would be the error here. But unfortunately there was some data in the table which was there with the value (Ex:date of joining column) 1-1-9999 So my sql statement has tried to add 12 months to this and it had caused this error.
