After reading about the new CSS backdrop-filter I decided to see how much work would be involved to create an iPhone like interface using HTML, CSS, and React.
Configuring a Raspberry Pi Zero for the first time just got a lot easier.
When you read about using Raspberry Pi cameras as part of your home security system, most of the information you will find will point you in the direction of running motion which is the de-facto standard for doing video motion detection on Linux. There are also variants of motion such as MotionEye or motionEyeOS which provide a nicer UI on top of motion.
Motion requires some horsepower to handle the video processing to detect motion, and also to run the web server and other features. On the modest hardware on the Raspberry Pi, I was only able to reliably achieve 4-10 frames-per-second at 800×600, depending on the Raspberry Pi model in use.
Using this technique below, my camera system is now able to get the full resolution for each Raspberry Pi camera which is 1920×1080 at 30 frames per second.
Sometimes it’s a pain to keep track of your Raspberry Pi’s IP address. Maybe you want to plug it in on a work or friend’s network without having to plug in a keyboard and mouse. This technique is what I am using to know the IP address of my Raspberry Pi’s no matter how often they change or what the IP address is.
This is how to create a OS X El Capitan installer on a flash disk or external disk.
Download OS X El Capitan from the App Store. When it finishes downloading, quit the installer. The “Install OS X El Capitan” application should be in your /Applications folder. On a side note even if you do not create a bootable installer, it’s a good idea to get a backup of this installer before running it. After upgrading your system, the installer will remove itself.
Format a flash stick Mac OS Extended (Journaled) with GUID Partition Table
Name the disk “Untitled”. Simply because the command below references the disk by the “Untitled” name.
In Terminal, run:
sudo /Applications/Install\ OS\ X\ El\ Capitan.app/Contents/Resources/createinstallmedia –volume /Volumes/Untitled –applicationpath /Applications/Install\ OS\ X\ El\ Capitan.app –nointeraction
If you use Zoom controls from Accessibility system pref, and using an external monitor, you may have experienced *very* slow performance after upgrading to Yosemite.
One workaround is to set Zoom Style to “Picture-in-picture”.
tcpdump out ASCII characters and not see headers
-s Snap Length – Grab the entire 1500 byte packet
-l stdout line
When you touch the Messages title bar, then click somewhere else on your screen, the messages app will move as if you dragged it. Such a strange bug and it was not sadly addressed in 10.10.1. Reproducible on any Mac, every time. How this could slip past QA is beyond me.
After installing Amazon Music on my mac, I noticed this background task “Amazon Music Helper” running. I tried to kill it, it came back.
The fix I used was to remove execute permission on that file:
Then kill the process again and it shouldn’t come back.
I have bought music since then and find that all the features (that I use) work fine. This thing isn’t even needed!
