I have recently started to watch some videos posted by LinusTechTips, JayzTwoCents and some others - all YouTubers that make videos mostly about computer hardware reviews. As much as I am sometimes entertained, the serious lack of scientific rigour makes me cringe sometimes.

These are not purely entertainment channels. They are supposed to be informative and accurate with some humour sprinkled atop. What is the point of hardware reviews if they contain factual errors or incorrect conclusions due to poor scientific methodology? No matter how much you want to be entertaining, if your main focus is to provide an unbiased opinion on something that is based on (true) facts, then you need to get the science nailed down.

I am going to tackle a specific video today. To best understand my rant, please view the full video (17m13s) first.

In the summer this place usually lights up with dandelions and buttercups. Dandelions are not the prettiest flower but when they turn into seeds things sure do change dramatically:

I have been using Apple Airport WiFi access points for the longest of time, and they used to work quite well. However, I found that their coverage were not always too great. If you have three stories or many walls between the access point and your device, the link quality will suffer greatly. The obvious solution is to add another airport and use it as a range extender. That works - to an extent. Bandwidth is reduced and the devices attached to the extender does not have near as reliable link as when connected to the main access point.

You can always hook up an ethernet cable to the second airport and put both on the same network, called a roaming network. But I never had terribly good experiences with this as it was hard to manage and know when you are connected to which base station (it is possible, but awkward as sometimes only MAC addresses show in Airport Utility).

Moving to two Unify AP-AC-Pro in mesh configuration solved all my issues. The best performance I have yet measured for a transfer from a device on ethernet to a WiFi enabled MacBook Pro is show below. That is using a file copy from the LAN machine to the WiFi machine using AFP. 1m22s to copy a 5.6GB file is not too shabby for WiFi.

Many people, especially millennials, question the practise of printing one's (digital) photos. With the prevalence of social media, including sites such as Facebook, Instagram, SnapChat, Flickr and so on, sharing your photos is so much easier when sticking to a digital workflow. Besides - digital photography costs nothing (except for the initial investment in equipment). Printing can be very expensive.

This is not a long, detailed debate. It is a singular observation as there are many arguments for printing your photos, in addition to the reason discussed in this post.

Take a look at this photograph I took a couple of days ago of some wild flowers. My computer monitor is based on an IPS panel, so although it cannot render all Adobe RGB or P3 or even sRGB colours, it is considered much better than many computer / mobile phone monitors out there. It is colour calibrated as well. Take a look what happens when I ask Lightroom to simulate which colours will be clipped when rendered on a device that can display all sRGB colours (the standard used on 99.9% of all computer monitors):
