It was more of an accident that made the 7805 the only thing that stood between a computer and a reversed main power supply. It would have been quite acceptable if the 7805 had died, but protected the computer. It took me only one or two seconds to get what was happening and cut power, but in that time the 7805 got so hot that the solder started to melt.
But everything went well. The 7805 and the computer were both ok.

You want us to spend $x million dollars/year to protect against an extremely rare manufacturing defect by a 3rd party and reduce the volume we have available to cram battery into our devices!?!!
You're fired, the money we save by not doing your crazy idea will buy a solid gold toilet for the executive wash room, not paying your salary will let us also install a solid gold door nob.
And thus when a crappy factory does mismanufacture a reversed polarity cable, it does blow up everything it gets plugged into[^].
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, weighing all things in the balance of reason?
Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful?

Apple's 'lightning' connector for iPad is reversible. A nice little plastic tab with eight connectors on each side so it is easy to plug in.

Well played. Apple did something right in their proprietary technology that they charge double for. 
I use Android phones but whenever I plug in my wife's iphone for her I always like the ease of it.
And I too often try to plug in micro usb the wrong way. All the time.

I was a bit looking around on everything I would like if ever I would have any money and came across this guitar[^]
It doesn't even have 1 review! How can you buy anything so expensive without reading any reviews!
All jokes aside, not sure how you warrant this price for a guitar though... 2000 EUR, yeah sure. even 3000 - 4000 EUR, but anything above that  ?
I could not buy this guitar even if I sold my entire studio at home.

Is that really the question? We all probably have a money sink, but after a certain point money does not buy you any more satisfaction with your favorite toy. If it does, then obviously showing off is your real hobby and not whatever you claim it to be. I have a old guitar that is made out of plywood, cost next to nothing and sounds surprisingly good. A more expensive guitar would not be able to compensate my lack of talent and also only have collected dust over a few decades. Fortunately I have more talent for my new expensive hobby thing (which is often mistaken for a guitar in its bag). Still, it's about 10 years old, I'm at least the third owner and I got it at less than a third of the price of a new one. That does not make it any less fun.

Why would you rely on the opinion of a small, self-selected group of Internet trolls to inform your decision to purchase something so expensive??

There's a typo in the last panel - s/resemble/reassemble/ 
If you have an important point to make, don't try to be subtle or clever. Use a pile driver. Hit the point once. Then come back and hit it again. Then hit it a third time - a tremendous whack.

I'm trying to use Edge - for compatibility reasons with a customer - big "we can't go wrong with Microsoft, you will be assimilated, blah, blah, blah" shop. I have purposely stayed away from Edge, because my first attempt strained my brain.
I'm back for round 2.
All I want to do is grab the web address location from the title to the Favorites folder. In Chrome and FF, I can just drag and drop. I think it used to work in IE. With my daughter's help, I have conquered the puzzle.
Microsoft  why?
Does anyone know if Microsoft has a Hall of Shame? Perhaps the Cone of Shame?
Rant over.

I have just used Edge in earnest on the WookieTab - I thought I'd give it a try - and ... decided it's still useless and installed Chrome.

Never visited it, but you could try their Visual Basic website.

Microsoft's strength has never been high technical acumen. Their strength has always been and will always be putting stuff together the rest of the industry does first and packaging it to businesses and consumers. This will never change. And it apparently works since most people aren't really technical anyway.

I tried using Edge and stopped because of compatibility reasons. It won't work with a very simple, twenty year-old web page so I bagged it.

two (clenched teeth) bios flashings later ... as Joan Murt said, and others agreed, Lenovo's software for managing driver updates is excellent.
hi-res screen really makes a difference in text clarity ! it also means that using the recommended 3840x2160 resolution results in the loss of WYSIWYG fidelity between Form appearance in the Visual Studio designer and what results when you run your app. yep, i'm reading up [^] on the hi-dpi additional settings, but, so far, there are no combinations of config and manifest mods, setting the Form's scaling and auto-size properties that are really acceptable.
so far installing my key apps, and syncing up to GDrive, DropBox
OneDrive, and Zoolz going great. beast auto-installed a driver for Logitech wireless mouse in a snap.
the only real problem is the back-lit keys (color is fixed at ominous red): at the brightest of the three levels they are very hard to read ... the keycaps are surrounded by bright light, but the letters are not translucent ... the visual gestalt is like being in a Dario Argento giallo horror flick (which gamers get off on, I assume)  this will pass, since I will be using an external keyboard where i can touch-type. the keys on the Dell 3570 are much easier to type with.
of course i hacked away a lot of Win 10 stuff i'll never use, and removed some Lenovo stuff ... pleasantly surprised by how little bloatware there was.
wading through the swamp of Win 10 settings and turning off all kinds of monitoring and settings took a while. further tweakings of Win 10 using Sergey T.'s excellent WinAero Tweaker (free) [^] 15 minutes, or so.
yeah, all this took a day, but, compared to installation/upgrade/migration nightmares of years past, this was easy street.
So, here's the current body-count:
Agent Ransack x64
CCleaner
Emsisoft Anti-Malware
f.lux
Google Chrome
Internet Download Manager
NordVPN
Old Calculator for Windows 10
Puran Defrag 7.7.1
Start10
UltraEdit
Visual Studio 2017
Atomineer Pro
JetBrains ReSharper Ultimate
PostSharp Ultimate
VLC media player
WinAero Tweaker

The Lilliputian religion says an egg should be broken on the convenient end, which is now interpreted by the Lilliputians as the smaller end. Big-Endians gained favor in Blefuscu.» J.

No PDF reader or zip utility (7Zip) or photo editing tool (PhotoFiltre)?
I bought FileLocator Pro (Agent Ransack) after so many years. In addition to this, I find Bulk Rename Utility extremely useful.
