wrldos··on About Security Keys for Apple ID
Cost is not a concern.
wrldos··on The Disappearance of the Ashtray
Just missed that. They had been confined to the smoking room however. It stank so badly I brought my own keyboard and mouse in which could not be touched ok penalty of death and a fat can of air freshener.
wrldos··on About Security Keys for Apple ID
Ahha I missed the "at least two" part. I can get behind that no problems at all. Now all I need is a USB-C hole in my iPhone...

Edit: ok they come in NFC as well. There goes €100...

wrldos··on About Security Keys for Apple ID
What happens if you lose your Yubikey? Are there scratch codes?

It's bad enough now if your house burns down with all your iOS devices in it.

wrldos··on iOS 16.3 Is Out
I only ever write it as defect / feature prefixed.

I never write the resolution as I am fallible!

wrldos··on Hewlett Packard HP-15C Simulator
How is the DM42? I really want one but don't need it :)
wrldos··on Hewlett Packard HP-15C Simulator
Still use an actual HP-12C daily. Been going strong for 35 years now and only had the batteries changed twice.

Had a 15C when I was an EE but it got sold on eBay when I discovered how much money it was worth.

wrldos··on Ask HN: Best Layman's Book on Electricity
Credit is very much given but the spirit of the original work is lost under the layers added over the top.
wrldos··on Ask HN: Best Layman's Book on Electricity
It's not in any errata. It's a complete misunderstanding of the problem domain and modelling. I don't like to crap on the authors too hard, but they are both hobbyists on the EE side of things and really shouldn't be writing authoritative material on the matter.

The only way to outline this is to do better which I may do if I ever get the time to do so.

wrldos··on Ask HN: Best Layman's Book on Electricity
Comments about impedance and the BJT calculations were completely wrong. Also it suffers from having bits of information in little islands and no clue as to how to stick them together.

One of the fun things in electronics is when someone builds a small signal amplifier then wonders why the output is lower than calculated with zero understanding of source / load impedances. Because no one taught them about that.

wrldos··on Ask HN: Best Layman's Book on Electricity
The entire content from this was open source and they built a community and advertising network around it and slowly devalued the content. I’m not sure what they did license wise with the original.

The original source material is out there still but I can’t remember what it is called or where it is.

wrldos··on Ask HN: Best Layman's Book on Electricity
I would stay away from practical electronics for inventors. The book historically was chock full of really bad explanations and mistakes which brings into question the author’s knowledge and credentials. You don’t see that until you look at it from the professional side of things. To a new electronics person it looks credible. I can’t speak for later editions.

The Art of Electronics is an excellent book but misunderstood. It’s a reference book not an introductory text. It should be used in a professional capacity or be read alongside the accompanying student manual.

The book situation in this sector is pretty horrible unfortunately. The old NEETs stuff is verbose but teaches you nothing, the Make books teach you what but not how. Same with the Forest Mims books.

I have been considering writing a book which covers enough electronics for people to competently solve a problem they have without being led up the wrong path or delve too heavily into mathematics (the latter is unfortunately mostly unavoidable but basic algebra should be enough to solve nearly all problems)

I have. All I'm saying is this plus someone who left 10 years ago who can't and shouldn't have written a CSV parser using regular expressions. Input row:

Mine is principal dung roller.
wrldos··on Ask HN: Why is on-device search terrible?
I don’t use search. I carefully put things where I will find them.
wrldos··on How to own an airline in 3 easy steps and grab the TSA nofly list along the way
Oh don’t. I spent several hours last week unfucking one of those.
wrldos··on Plant-based meat is turning out to be a flop
Completely agree with this. As a vegetarian I'd really prefer to eat meat over the synthetic meats. The reason being the texture, flavour and nutritional value isn't there. They're also expensive, covered in horrible packaging, don't keep very well and are difficult to cook.

99% of the important bits of a dish don't come from making something meat-like but cooking something that isn't bland and uninteresting. And you don't need fake meat to work around that.

wrldos··on Salesforce, but for Dating
Narcissist flag was missing in my original dataset.
wrldos··on Salesforce, but for Dating
Note that it's not universally true around the world. In the US, yes. If you do this in the UK, it will result in an evening where you end up ordering a taxi and slipping out the back door while two women are pulling each other's hair extensions out outside a pub and trying to beat the opponent with a shoe.

Yes this actually happened to me.

wrldos··on Salesforce, but for Dating
I did this a loooong time ago before there was really internet dating. Had a decision analysis tool I wrote in excel 97. Married a match in 2002. She was a crazy narcissist and made my life misery for 18 years until I divorced her.

Beware the tools you create, for the input corpus isn't necessarily valid over time. People change.

wrldos··on New Mac Mini
The big thing is the Mac Studio is an out of box config and the M2 Pro is custom. It's risky relying on custom Apple configs from experience as the turnaround for repairs is much longer.
wrldos··on MacBook Pro featuring M2 Pro and M2 Max
You’re not wrong. Fun times :(
wrldos··on New Mac Mini
16Gb is minimum on M1 I found. I hit problems on my 8Gb machine regularly. It’ll work fine but you do get heavy pauses.

The thing to be careful of is if your custom config breaks then the turnaround to fix it can be a couple of months. Ergo only buy stock configs. That makes the market somewhat less friendly.

wrldos··on MacBook Pro featuring M2 Pro and M2 Max
I ran thinkpads for years. There is a nice market for previous generation ones new in box with 3 year next business day warranties for stupid money. I got my daughter a 13 month old T495s for £600 for example. That’s still under warranty now.

But yeah I’ll bitch and moan and just give apple the money like I always do now n

wrldos··on MacBook Pro featuring M2 Pro and M2 Max
Yeah I have a rather large and horrible stacked Dell 7670 here. I mostly use my MBP as a desktop machine though.
wrldos··on MacBook Pro featuring M2 Pro and M2 Max
I can get an i7 T14 gen 3 with 16GB RAM and stick a new SSD and another 16Gb RAM in it for < £1500
wrldos··on MacBook Pro featuring M2 Pro and M2 Max
Yeah likely but the thing is that Apple prices never go down even if the exchange rate becomes favourable.
wrldos··on MacBook Pro featuring M2 Pro and M2 Max
Pricing has gone crazy here in the UK. Paid £1899 for my M1 Pro. Same spec M2 Pro is £2199.

Edit: at this rate when my previous gen one expires I'm going to think seriously about shifting back to ThinkPads...

wrldos··on The art and science of spending money
I'm sure it'll wear off one day but I'm going to live it now.
wrldos··on TAB electronics books
Was short on time yesterday. Will elaborate today.

It's a little different from the abstractions, which are of course, poor but that's less important. There are two Mims camps as a rule. Those who bought the books and perhaps read them and didn't build anything and have fond memories. Then there were those of us who actually build stuff out of the books and experienced the hell that is debugging a poor design with no skills or knowledge. My entire early days of electronics were unfortunately constrained by these books. The only reason the books existed was they looked cheap, cute and simple enough for Radio Shack to sell lots of copies and use that to leverage a hobby industry. They were not quality material and in fact were quite frustrating and destructive. Throw on the dubious quality of some of the components on the market back then (fuck you Radio Shack MPF102) and it was a mess.

Regarding The Art of Electronics, I was given the first edition of this back in the late 1980s and jumped right in. Whilst light on theory intentionally, the book is actually backed up by a lot of professional experience in the industry. There is a student guide/laboratory manual that goes with it that deals with the applied side of it as well so at a basic level they should be considered together. This book turned everything around and led to an EE career.

Roll on a few years from there, I had managed to self teach away most of the nasty, learned algebra at school, jumped into theoretical side via Sedra/Smith. After that everything worked every time. I have a box of 35 year old failures somewhere I will analyse at some point. I did consider opening a YT channel for this but time does not currently allow.
