The :g command and it’s reverse :v This Global command is quicker than the typical :s/old/new/g instead the syntax is [range]g/pattern/cmd which is way more general. For for instance, if you wanted deleted all the lines with with world “hello” in it, you type :g/hello/d And there is reVerse version so, :v/hello/d means delete all…

So I keep forgetting how useful macros (and registers are) or repetitive things. Basically, Vi has 10 numeric registers and then alphabetic registers. If you want to see them then type :registers and you can see what is stored there. There are two ways to use them. The first is to stick thinks into a…

In the same way that there is essentially just one mechanical watchmaker, one sunglasse maker and one optical company, there is an incredible concentration in the home theater maker. Like skis and other passion projects the key is to find an independent group that cares about the product. And not a gigantic conglomerate looking for…

Argh this is so complicated and the problem is so silly. So one of our phones is working and the other wasn’t. The short answer is so silly: The checklist What was happening is that I would go to the site but there are a host of requirements to make this work: Enable wifi calling….

Well, dual SIMs is a useful feature if you have a work and home number and want to get calls on one phone. Of if you travel a lot and want a local sim. The trick here is that starting with the iPhone XS, Apple supports an eSIM, that is an electronic SIM, so no…

First of all hat tip to Sam on this one. With the new iOS 15 you get both widgets and an App Library so you don’t get endless pages of icons anymore. But the question is how to use all this effectively. Getting it right with Focus, Home Pages and Notifications Right now, I have…

Well, the really cool feature Universal Control where you can just have one keyboard and work across multiple Apple devices isn’t yet here. It turns out it less magical than you think but still awesomely cool. So even without this new feature you can use your iPad as a second screen. Pretty valuable when you…

Well, in the US things are pretty (unfortunately) locked up. Yes, there are some pre-paid carriers, but the triopoly of AT&T, Verizon, and T-Mobile are pretty incumbent.
