Comment Re:Apple bears some responsibility here. (Score 1) 92

Insulation plastic falls apart after a year? Hm, tell that to the PSU for my Macbook Pro bought in 2012... Still in perfect condition. But then, I never wind the cable using the ears, I always just wrap it around the PSU itself while leaving a generous loop from where the cable exits the PSU.

It has nothing to do with how you wind it. I've seen Apple power supplies that were never wound up at all where the outer insulation became brittle and flaked off in large chunks. I'm not sure if it was sun exposure or heat exposure, but something causes the jackets on the early MagSafe cables to chemically break down.

Comment Re:Apple bears some responsibility here. (Score 2) 92

Case in point: Mac laptop chargers have been known to suffer from frayed cables due to Apple's insistence on a design that lacks adequate strain relief. This has been a known engineering defect in their chargers since the PowerBook G3 series design almost two decades ago ...

FTFY.

As far as I'm aware, Apple has never in its entire history built a good laptop power supply:

  • The original PowerBook 1xx series had connectors that kept breaking. IIRC, the 5xx series was similar.
  • The G3 series had a ferrite choke a quarter inch from the plug, and that quarter inch of wire constantly broke, causing fires, so they recalled the entire lot of them and replaced them with the yo-yo power supply.
  • The yo-yo design had no real strain relief, and even better, had thinly insulated wires inside a steel-braided shield that over time wore through the insulation, resulting in cables that sparked internally. In a dark room, you could see little blue electrical arcs in the middle of the wires.
  • The iBook power supplies had inadequate strain relief and broke right at the plug end.
  • The T-shaped MagSafe connectors had the same problem.
  • The L-shaped MagSafe connectors were usually more reliable, though they still eventually fail at one end of the wire or the other, but the MacBook Air version was notoriously bad.
  • And MagSafe 2 is a disaster of failed strain relief.

So saying that third-party Mac laptop supplies are worse than the real thing might be true, but it is like saying that a Pinto is worse than a Corvair. They do, however, build reliable USB power supplies... but their cell phone power cords are even worse than their laptop power cords. Fortunately, there are many third-party manufacturers building Lightning cables that are actually built to last.

Comment Re: Apple problem mostl or platform-independent is (Score 2) 92

Part of what makes these problematic is largely that they're trying to look like Apple products. Apple makes really small power supplies, which makes it much harder to create knock-offs that work. Nobody makes knock-offs of Android supplies; they just make cheap USB power supplies. Because they aren't trying to hit an absurdly small form factor, they don't cut corners to the same degree, and the supplies tend to be more reliable at a given price point. That said, the Apple USB supplies cost $19, and the usable third-party branded supplies usually start at about $12, so there's not a lot of savings to be gained even when you take away the form factor.

More significantly, because they're trying to look like Apple products (and often pretending to be Apple products), they can't be branded. If they were, Apple would go after them for violating their design patents (and trademark violations if they use the Apple logo). That entire selling model is incompatible with branding. As a result, there's no hit to their reputation if the product doesn't work. They just change the name on their Amazon or eBay account and go right back to fooling people. So there's also no incentive to make a quality product.

Comment Even ones that are tested can have problems (Score 1) 92

I bought an Anker USB C-C cable. I got an LG phone with C, and Qualcomm quick charging on it so I needed some new adapters to be able to charge it at full speed. Gout a couple of adapters, and couple of A-C cables and then said "why not?" and got a C-C cable too. No use for it yet, but I figured I'd get it since I'm sure my next laptop will have C on it.

A few weeks later, Anker sent me a recall notice. Apparently there was a problem in the cables that could cause issues with high power use cases so they gave me my money back and promised a replacement when available.

The issue was actually apparently in the ICs on the cable. Yes that's right, the cables have to have controllers on them too since they have to communicate what kind of power they can handle.

It is likely to be a problem for some time. The good news is A-C cables aren't such an issue since A supports much lower voltages and currents (can only go up to 12v and and like 2.5a) so they don't have to be as insulated and don't need as much protection (apparently a resistor on them does the trick) but still. The C-C stuff though, it will be an issue.

Comment If you do business in the US, the IRS gets to peek (Score 1) 196

You find it is true of most nations, actually. If you are playing with finances in their borders, their tax agencies get to have a look at what is going on. Doesn't matter if you are a citizen or not. There can be tax implications even if you are't a citizen but regardless they want to see what is going on.

I mean look at the FIFA guys who got brought down by the US: It happened because they were doing shit with US currency and US banking. That is why the US took an interest and has legal standing.

Think about the power to weight ratio--with as little as a plastic vehicle with a passenger or two would weigh on Ceres, the ratio would be very high, especially after they found the ferromagnetics in the belt that could be magnetized a hundred times as strong as today's (that story, "The Pirate", is still in edit), replace the magnets in a 100 watt motor with them, and one watt will run that motor as well as 100 did the old.

They already had real moon buggies, they're still up there. They used wheels, but the moon is a LOT heavier than Ceres.

Imagine playing basketball on Ceres? I might add that to a story, there were microgravity sports in "Mars, Ho!".

I don't back up daily, more like weekly, plus whenever I have a rash of new data. I keep the backup drive unplugged except when backing up, and never in s thunderstorm. Losing my non-backed up data would only hurt a little, it isn't like I'll lose a 10,000 customer database or anything.

Before I retired, backups were automatically done daily by software. I had to change the backup tapes weekly.

Journal Journal: Santa Killed My Dog!

They say that Santa's coming,
He comes 'round every year.
He comes he'll meet a shotgun slug
'cause he ain't welcome here.

Five years ago this Christmas
The fatass came around
With jingle bells and ho ho hos
And looking like a clown.

He came in for a landing
As I let out a yawn
My house is pretty little
So he landed on the lawn.

Those were all bad presidents. My grandmother, born in 1903, said Coolidge caused the depression but Hoover was a terrible president, too. Most historians consider Lincoln's predecessor, James Buchanan, .was history's worse.

I never thought I'd ever see a worse president than Carter, but GW proved me wrong.

You can always kill the phone's sound before bed, and check messages when you get up. You kids just don't understand that answering your phone, whether talk, text, email, amber alert, or presidential alert is NOT MANDATORY. If you're driving, leave the damned thing in your pocket, whoever is attempting contact can wait until you get where you're going.

Stop being a slave to your phone!

If it looks like there may be tornadoes that night, you might want to let the presidential/amber alerts annoy you.

Previewing this, I laughed; this font makes "tornadoes" look like "tomadoes" (I've seen "tomatoes" misspelled like that before).

Do you work for Maxtor or something? I've had hard drives for decades, few have failed and the failures weren't brand specific, and all were old when they died.

Did you have it sitting next to a heater vent or something? Solid state electronics hate heat. I've had a 3TB Seagate for a couple of years now.

I do avoid Sony like the plague, because if you buy digital electronics from someone who deliberately vandalized your PC with malware that came on a Sony-BMG music CD your daughter bought in a record store, you're a fucking moron.
