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. ...

I’ve been running my music system at home using Squeezebox Server software for many years. It has served me well, but Logitech bought the entire eco-system and then abandoned it. Because it’s Open Source, it’s still updated, but it’s time to do an upgrade to a better system. After testing a lot of different server solutions, I finally choose Roon by Roon Labs as my music server software. Here’s why. ...

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. ...

If you leave your PlayStation Motion Controller without charging it for a long time, the battery will not charge. Even after you press the reset button, the controller refuses to recharge. Replacing the battery is an easy fix, but expensive, and there is another way of getting the PlayStation Controller to work again. ...

There’s been a lot of chatter on the internet of the “Ambien defense”. It’s quite a good defense for weird behavior. I’m talking as a recovering Ambien abuser for over ten years. ...

Just got my new Aneng AN8009 Multimeter in the mail. I’ve made an old post about improving the responsiveness of the Aneng AN8008 in an earlier blog post. I loved that meter, but I gave it to my son who is just beginning on his electronic journey. So naturally, I needed a replacement. After checking eBay, I found that there’s a new model, the Aneng AN8009 so I decided to get that model. It has the same problem that the Aneng AN8008 had; it’s slow to settle on a value when measuring. Fortunately, my old modifications work on the Aneng AN8009 as well. ...

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. ...

I’ve written an article on how to remove the purgeable portion on a hard disk on MacOS, but in High Sierra, Apple has changed the file system from HFS+ to APFS. Because of that, my old guide doesn’t work. So here is how to remove the Purgeable part of the disk in MacOS High Sierra. ...

I’ve recently got interested in RF radio. But I live in an apartment, so I can’t do any installing of large antennas. So after doing the obligatory Google search, I narrowed it down to two antennas. The Wellbrook Loop Antenna and the (much cheaper) PA0RDT Mini-Whip. Being short of cash, I decided to buy a cheap Mini-Whip from eBay. ...

Update: Apparently WeMo took notice of this article and contacted me. They have now sent a replacement unit. I also got an email from the people at Airspy, who mistakenly thought that this blog post was directed at them, which is not the case. The reason for me to choose Airspy is because they make quality products at a really good price, and I plan to do a blog post about using the Airspy Mini as an ADS-B receiver. Thinking of buying any radios, antennas or other radio amateur equipment from WiMo Antennen und Elektronik GmbHI? Think again! I wanted to buy an Airspy Mini to use as a makeshift simple spectrum analyzer. Usually, I buy directly from the manufacturer, but I wanted to be sure that if something were wrong with it, then it would be easier to have a seller closer to Sweden, so I decided to buy from WiMo Antennen und Elektronik GmbH in Germany. That turned out to be a mistake. ...
