PayPal Two-Factor Authentication in 1Password

February 13, 2019 by Jack Zimmermann Leave a Comment

PayPal has now added 2FA, so this info is no longer needed. Kept for posterity.

Two-factor authentication today is a must to keep your online accounts safe. You certainly want to keep your PayPal account safe. Using SMS to add an extra authentication is a hassle and could cost you money as well. PayPal, in their infinite stupidity, has chosen not to use the regular 2FA two-factor authentication used by most of the online sites. Instead, they decided to go with Symantec/VeriSign’s design, where you need a proprietary iOS, Android app, or a dedicated hardware key. This method makes it very hard to get it to work with the worlds best password manager software, 1Password. However, with some elbow grease, there is a way of getting it to work. Here’s how.

MacBook Netflix Flicker Flashing in Full-screen

December 25, 2018 by Jack Zimmermann 46 Comments

I had an annoying problem on my 2015 MacBook Pro Mac OS when watching movies on Netflix using Safari. When in full-screen mode, the display would flash/flicker a couple of times a minute. Well, after digging around, I found a solution for it.

Why Does the screen keep flashing when watching Netflix?

Some MacBook Pro’s have dual graphics cards. Mac OS switches between them depending on what kind of work you are doing, and by switching cards it saves batteries. Unfortunately, the built-in Intel graphics cards are the reason for the flickering and flashing. So we need to turn on the high-performance graphics card when watching Netflix.

HifiBerry DAC+ Click When Changing Song

April 6, 2018 by Jack Zimmermann 6 Comments

My current music setup is a Raspberry Pi 3 with a HifiBerry DAC+ audio card as my music player. It works perfectly, except for one annoying thing. The new HifiBerry DAC+ makes an audible click or poping sound when changing the sampling rate. I have a lot of recordings in higher resolution than CD-quality of 16-bit 44kHz, so it’s jarring when it happens. I like to play my music loud which exacerbates the problem. But there’s an easy solution, and at the same time, you can get better sound quality overall. Here’s how to fix the problem.
