How to download older versions of macOS after Mojave was released

My good old MacBook Pro from 2011 can only supports macOS up until 10.13 High Sierra. It’s been purring along nicely with macOS 10.12 Sierra for the last couple of years, and I didn’t see the need to upgrade just yet. Why risk breaking things that are working, right?

A couple of weeks ago, macOS 10.14 Mojave was released, with which my MacBook is sadly no longer compatible (not officially at least). So when I searched for “High Sierra” on the Mac App store, I was surprised to learn that it didn’t come up. It appears that only the very latest macOS release is available to download from the Mac App Store.

So now the $100k question is: How can I get an official copy of macOS High Sierra, now that Mojave is out? I’ve never downloaded it before, therefore it doesn’t show up in my “previous purchases” tab either. Have I missed my 12 month window to download the last operating system that’s compatible with my hardware?

Lucky for us, Apple have made some contingencies. I did some research and found several older Mac operating system for ya’ll’s enjoyment. Might come in handy 😉

Blue Yeti vs ZAFFIRO – Microphone Comparison ASIN B07BVRQD8G

I was looking for another desktop USB microphone for my second desk. Currently I’m using a wonderful Blue Yeti with my Mac on my main desk (or Studio A as we like to call it), and every time I do a screencast or podcast on my Windows workstation (or Studio B as we’d like to call it), I have to bring over the Blue Yeti.

So I discovered the ZAFFIRO Desktop USB Mic, for over $100 less. I thought I’d give it a spin – and I really like it. Here’s what I found after a couple of weeks of working with it.

Ruipu Power Bank Review: 24000 mA⋅h with Solar Panels (and how to use it)

Last year, in September 2017, I ordered a RUIPU 24,000 mAh Solar Power Bank in preparation for Hurricane Irma here in Florida. I’ve had a whole year’s worth of experience with this gadget and decided to buy another one.

This thing rocks! Let me tell you all about it, and how to use it in this review.

How to transfer files from your GoPro to your computer via WiFi

There is an iOS and Android App available to transfer files directly from a GoPro camera to a mobile device. Those apps transcode files and compress them for easier viewing, and to save storage space.

While that approach gets footage onto my iPhone, I still need to transfer the files to my Mac for editing. Plus, there’s an additional compression step involved which can’t be good for picture quality. Besides, it takes forever to do its job.

A much more useful approach would be to hook directly into the GoPro and transfer files that way. This leaves the SD card place and doesn’t disturb the (sometimes hard to reach or difficult to recreate) position of the camera.

Here’s how to do it.

How to centre an element in CSS

In the olden days of HTML development, in the late 90ies, we only had inline styles. Centring an element was done using the <center> property. That approach isn’t very elegant anymore in modern CSS 🙂

Today we can use something like this:

It’s slightly more complicated than a single tag, but also opens up more options to tweak top and bottom margins at the same time.

How to add something to the_content in WordPress using PHP

Sometimes we need to add additional text or elements to the_content in WordPress. This can include links, icons, shout outs, author biographies, and so forth. I wanted to add an Apple Podcasts badge underneath each post in my podcast categories, adding a link to the badge, depending on the category. I’ll elaborate how I did this in a later post.

Right now, let’s have a look at how we can add elements to the content retrieved from WordPress. This should work independently of your theme, and no theme-file-hacking is necessary to accomplish this.

All we need to do is intercept the_content as it is requested, append our elements and return an amended version of the_content. Let’s see how this works.

How to find your Public Profile on Amazon

As much as I like Amazon, UI design isn’t their strong point. They have so many links to so many things hiding in their interface that it’s difficult to find what you’re looking for at times. Your Public Profile is one of those hidden gems.

It’s a collection of all your community activity you’ve engaged in on Amazon, such as post reviews or videos, your wish lists, Spark posts, Reviewer Ranking and so forth. Here’s a screenshot of what mine currently looks like:

ZAFFIRO Lapel Microphone comparison B074SF96X9 vs B0765NGK4N

In this episode I’m taking a look at two lapel microphones by ZAFFIRO. They’re both called “Lavalier Lapel Microphone”, and the description is more or less identical on both items – yet there are significant differences between these products.

I bought both of them back in March 2018, and given the sound quality and amount of accessories you get, for less than $20 each, these mics are good bargains for casual users. But no matter how detailed (or vague) their shop descriptions are, and no matter how hip the people in those pictures look, you can only really judge a microphone by what it sounds like.

In this review I’ll tell you all that I’ve learnt in my six months with the ZAFFIRO lapel mics.

How to bring back the date on Sticky Posts in TwentyThirteen

By default, the TwentyThirteen theme suppresses the date byline when a post is marked as Sticky (in which case, it’ll always be displayed at the top of the posts list).

That’s usually great, because Sticky Posts are often timeless announcements, and the fact that they’re a year or two out of date doesn’t look as handsome as if the date byline would simply be removed. I like this as a default behaviour.

Here’s what a default sticky post looks like, without the date displayed:

But of course, every now and again you may want to break the rules and shake up the whole universe. I did this on my iOS Dev Diary recently, where an announcement post would have been very helpful with the date displayed (I didn’t intent to keep it there for long).

So how do we bring back the date on Sticky Posts in TwentyThirteen? Let’s find out!

How to take a screenshot on a Chromebook

My wife recently got hold of an Acer Chromebook. She just got a promotion in her job, and part of said promotion was a laptop so that she can work 18 hours a day more efficiently.

The biggest question we both had less than 10 monies after switching it on was: how to we take a screenshot with this thing?

Short Answer

To take a full screenshot, press CTRL + F5.

To take a partial screenshot, press SHIFT + CTRL + F5. Now left-drag the area you’d like to take a screenshot of.

If your Chromebook doesn’t have F keys, look for a rectangle with two lines next to it. It’s known as the Switch Window key. It’ll most likely be the fifth key from the left in the top row, not including the ESC key. It looks like this:

Resulting files will be stored in the Downloads folder.
