Often times bash scripts I run depend on other tools. Tools that are sometimes updated. So once in a while I add the following curl command to download the latest tool.
curl -O [filenameURL]

Once in a while a window of an application goes off screen and it can't be moved or resized. I've seen various approaches to get the window back but by far the easiest is to change the resolution. Once you change the resolution all windows are moved to be back within the screen and you'll get the window back.

Here is a trick I learned many many years ago and it remains one of the best tools in my debugging toolbox for all programming languages. This example just happens to be in C++.

Programmatically creating windows without using a NIB file can be
tricky on the Mac. Especially if you're developing in C or C++ instead
of Objective-C. Here's one of the issue most common that may come up.
Assuming you got the window creation code right, you may be thinking everything is going to work, but you get this error:
Oct 30 17:34:39 myapp
Oct 30 17:34:39 myapp
This means your NSApplication is not being initialized. In other words, the Objective-C side of your system needs to be properly initialized. Adding the following line may help:
Most likely you aren't trying to do this so it is never an issue, but for those few souls out there this might just save you some serious time.

I'm closing in on 500 posts over the last 10 years, I know it isn't much but considering I don't actually post that much it's rather remarkable. I've also had well over 1 million views! So stay tuned because if you like to read my blog, I have some plans will bring even more of my ramblings to your screen.

It turns out I write quite a bit about ergonomics, and those are some of my most popular posts which is surprising but not too surprising since that is one thing that affects everyone.
Desk Ergonomics - Every Diagram on the internet is wrong!
Make the Apple Magic Trackpad Ergonomic
Ergonomics of Using a Cell Phone
All these issues are still valid, in fact maybe even more so. Sit-stand desks are more popular than ever, but they still aren't good enough. Companies like Fitbit and Apple have pushed wearable devices to help but relatively few people wear them and I'm not sure how much they really help. I personally don't wear a device like a Fitbit or Apple Watch. If this is an interesting subject to you as a reader of this blog, write a comment or like this post so I know to write more. I have a lot more information and access to people who know even more and I believe sharing information is good.

I've seen so many examples and questions of how to convert between unicode string and ANSI string using C++. So here is by far the easiest way to do this conversion that I've implemented:

On macOS, the native SSH client can use the built-in keychain directly which is awesome because you don't have to type in the password every time. To add your private key to the keychain simply use the command:
ssh-add -K /path/of/private/key
For example if your private key's filename is ~/.ssh/id_rsa, you would use the command:
ssh-add -K ~/.ssh/id_rsa
You will then be prompted to enter your password. From now on it's all automatic. Viola!
Update: There appears to be an issue in macOS Sierra where the password is only stored for the currently session. You can follow a thread here. I'll add more information as I run across it.

This is by far the best tutorial on blurred faces or censoring I've come across for Final Cut Pro X. The only thing I'd add is I suggest starting from the beginning, add the keyframe for the position and scale, then use the left and right arrow keys to jog and move the shape to the new position for each frame.
