The most common magneto-optical is Sony's MiniDisc. But there were ISO standard 3.5" and 5.25" magneto-optical disks with multiple manufacturers making drives and disks (along other proprietary formats). Magneto-optical disks were less "heat assisted" and more "heat mandatory" as the medium...

Not that I am aware of. There have been a number of optical disc technologies some of which had high (e.g. DVD-RAM, UDO) or unlimited (magneto-optical) re-writeability but AFAIK they were only used in removeable media (either simple drives or media libraries). They're not re-writeable actually.

It took at least 39 days to make one. Which is already impressive as hell. But they had many being built at the same time and had a new finished ship every day or two.

This was the larger Switchblade-600 model. The warhead is AFAIK the same as in the FGM-148 Javelin missile.

Bankrupt. Nope. Neither content distributio nor common consumer needs of physical media contribute much to elevate the market for long term stable media. E.g. AFAIK virtually every LG DVD/Blu-ray makes for computers writer can write M-DISCs. M-DISC however went bankrupt because the market for...

xDSL max speed drops drastically with distance. At 200 Mbit/s (maybe x2 100 Mbit/s) the other poster is probably less than 500 meters from the xDSL cabinet. In a lot of contexts telcos would rather go straight to FTTH than install xDSL cabinets within a few hundred meters from the customers...

I'm not sure Putin will agree to any of that. I guess that's probably Zelensky's game right now: have Putin make Trump lose face.

The goal is to store a loop a of fibre without any sharp bends. So the shape is made to give a smooth transition from and back to the linear section.

a) because Russia b) because the Christians in Aleppo aren't aligned with Assad c) because Russia

Any individual, company or organization is at risk of lawsuits for million reasons, real and frivolous. The solution for this is a) don't break the law so there are no real reasons to sue you. b) have an efficient justice system which can deal with lawsuits in general and frivolous ones in...

Search for USB-C to Magsafe1 (or 2). e-Bay, Aliexpress and etc have plenty of them. E.g. https://www.ebay.co.uk/itm/384709391251

A layout DRC covers just things like thickness and distance of traces and etc for things like manufacturing and signal integrity. I don't design PCBs but I'm pretty sure the tool my colleagues use (Altium) doesn't even have the option to set the kind of rules you'd need to detect a reversed...

Even now a lot of PCBs go into production without much beyond layout vs schematic and layout design rule checks. If the capacitor polarity is already wrong in schematic it will go unnoticed.

This isn't a manufacturing defect. It's a design defect which somehow has gone somewhat undetected until people tried to repair old machines.

If I understood the article correctly the factory was installing the capacitor as per design. That is in the wrong polarity. Apple just got very lucky they didn't systematically blew up.

I can't really make head of tails of your explanation so here's mine: A capacitor consists of two conductive plates separated by a dielectric (a insulator). Two metal plates separated by vaccum form a capacitor. Two foils of aluminium separated by a plastic film form a common type of capacitor...

Modern boards tend to use solid electrolyte tantalum capacitors because in general they are generally more reliable and perform better than than old school wet electrolyte aluminum capacitors. Which is also why refurbishers tend to go for tantalum.

I hope Ferrari has a good car next year so we can see a competitive Lewis again.

He won 7 championships with 2 different teams and in the earlier Ferrari years squeezed out pole positions and race wins of out not very good cars. He wasn't above cheating but the son of a bitch really was damn good.
