Ubuntu: Fixing issues with apt-get after installing Steam client

By
After installing the latest Steam client (http://store.steampowered.com/) on my Ubuntu 14.04 using the Ubuntu Software Center, I decided to install another package using the package manager.

As a first step I ran apt-get update, which (you guessed correctly) failed fetching several index files:

Err https://private-ppa.launchpad.net precise/main amd64 Packages            
  HttpError401
Err https://private-ppa.launchpad.net precise/main i386 Packages              
  HttpError401
Ign https://private-ppa.launchpad.net precise/main Translation-en_US          
Ign http://security.ubuntu.com trusty-security/main Translation-en_US    
.....
... 
W: Failed to fetch https://private-ppa.launchpad.net/commercial-ppa-uploaders/steam/ubuntu/dists/precise/main/binary-amd64/Packages  HttpError401
W: Failed to fetch https://private-ppa.launchpad.net/commercial-ppa-uploaders/steam/ubuntu/dists/precise/main/binary-i386/Packages  HttpError401
E: Some index files failed to download. They have been ignored, or old ones used instead.


It seems that my /etc/apt/auth.conf pointed to an incorrect username (a user that was used to merge between 2 different accounts that I had), changing the username to my current username fixed the problem and I was able to update the index files with no errors/warnings.

That's all,
Tal Kain

IORegistryExplorer on macOS Dark Mode issue fix

By
IO Registry Explorer is a utility developed by Apple which allows you to watch the I/O Registry on your macOS. (Original:  https://developer.apple.com/library/archive/documentation/DeviceDrivers/Conceptual/IOKitFundamentals/art/registryexplorer.jpg ) If you are using the IORegistryExplorer on macOS while working with Dark Mode enabled, then you probably noticed the fact that the explorer doesn't fit the new DarkMode, hence the UI might look like that: Which makes it hard to read the content. I found this article  which shows you how to disable DarkMode for a specific application. Running the following commands: osascript -e 'id of app "IORegistryExplorer"' defaults write com.apple.IORegistryExplorer NSRequiresAquaSystemAppearance -bool yes Solves the issue and make it usable again. Have fun, Tal Kain

Ubuntu: Installing a missing ath3k firmware

By
While trying to prepare a new Ubuntu box to use a new card based on the Atheros chipset, I encounter the following error: Bluetooth: Firmware file "ath3k-1.fw" not found According to  http://wireless.kernel.org/en/users/Drivers/ath3k : ath3k is the Linux Bluetooth driver for Atheros AR3011/AR3012 Bluetooth chipsets. I saw this blog post: http://hexwave.blogspot.com/2011/04/debian-6-with-atheros-3011-ath3k-usb.html So I decided to try installing the package linux-firmware which contains the relevant file (I used  dlocate  to $ dlocate linux-firmware | grep -i ath3 linux-firmware: /lib/firmware/ath3k-1.fw or you can find it by searching for ath3k: $ dlocate ath3k-1.fw linux-firmware: /lib/firmware/ath3k-1.fw I just ran: # apt-get install linux-firmware and it fixed it by installing the missing firmware file. Good luck! Tal Kain

BinDiff error: "Can't start disassembler. Please set correct path in the main settings first"

By
After installing  BinDiff  and running the application for the first time on my Windows 7 x64 machine, I tried comparing two different binaries but got an error in the middle of the process: Can't start disassembler. Please set correct path in the main settings first The solution for this error is very simple: While installing BinDiff, the installation process asks for the installation path of IDA. The default path (on x64 machine) would be C:\Program Files (x86)\IDA\. This is not always correct. At my case the installation was at C:\Program Files (x86)\IDA 6.3\. Moving the path inside BinDiff will not be sufficient since part of BinDiff's files are still on the old directory. Easiest way to fix it (or by doing it in advance): Uninstall BinDiff and install it while pointing to the correct IDA's path. -Tal
