How the Ancient Egyptians (Should Have) Built the Pyramids

Joce640k Re:They made the blocks into wheels (185 comments)

The key failing of the cradle and the (actually extremely similar) pole theory is that it does not explain how they moved the far larger slabs that were not square blocks.

So they could only move 90% of the stones that way...

Yeah I guess that _does_ definitively prove they could never have used them for anything at all. Not.

How the Ancient Egyptians (Should Have) Built the Pyramids

Joce640k Re:Corroborating Hieroglyphics? (185 comments)

There's another fact that this theory ignores: Moving the blocks this way takes wood. Lots and lots of wood.

a) No it doesn't. Wood can be re-used.

b) They brought the stones in on boats, why couldn't they bring the wood as well?

How the Ancient Egyptians (Should Have) Built the Pyramids

Joce640k Re:Corroborating Hieroglyphics? (185 comments)

Anyone that actually lived in the middle east knows that sand is everywhere. They simply stacked the blocks while building up a sand pile around it, then eventually dug the sand away again

I think you massively underestimate the amount of sand needed to make a ramp up to something that tall.

How the Ancient Egyptians (Should Have) Built the Pyramids

Joce640k Re:Corroborating Hieroglyphics? (185 comments)

Why use rods?

If you're going to strap something to the stones why not use something a bit more rounded that turns them into actual circles?

PS: We know how they did it from paintings on the walls:

$125,000 Settlement Given To Man Arrested for Photographing NYPD

Joce640k Re:idgi (231 comments)

He was probably given two choices:

Option a: Receive $125000 today, go home, spend it.

Option b: Press charges, spend a fortune on lawyers for several years while they keep appealing (all on the taxpayer's dollar), maybe win, maybe receive some money.

London Police To Wear Video Cameras In Pilot Project

Joce640k Re:A camera can't prevent complaint cases... (152 comments)

If the cops have the footage, they'll show it.

If there's a mysterious gap in the video? The jury will most likely believe the arrested.

Joce640k Re:Can't turn them off? (152 comments)

How much battery do you really need though? Give an iPhone 20x the batteries and I bet you could record an officer's entire shift while also live-streaming the video to headquarters over the cellular network for backup, all in a package lighter than their pistol.

Yeah, that'll work. I can imagine the boys in a data center having a chuckle every time the hot policewomen goes to the toilet.

I think they should have every right to turn off their cameras, nobody should be constantly recorded.

OTOH they should expect a full investigation if they do it when they're in action or interacting with the public.

London Police To Wear Video Cameras In Pilot Project

Joce640k Re:Can't turn them off? (152 comments)

No, I think the issue is "if only such obvious solutions were actually *implemented*", which is something we'll have to force down their throats, because they certainly aren't going to volunteer to give up their ability to be huge bullies.

I'm pretty sure the "huge bullies" in the police force are in the minority (certainly less than half).

This could help weed them out if implemented.

So....maybe we can also implement some sort of system to combat that?

Maybe the cameras could record the 30 seconds prior to being activated.

Recording to RAM doesn't need much power.

Gee, if only there was a way to address that issue.

Like making them pay for repairs out of their wages, fining them for forgetting to wear their camera, etc.

But... I guess there isn't - because Mr. AC says so.

I'm shocked they can't turn them off. They must be able to turn them off to protect the public's privacy.

Clue: Not all video is uploaded to Youtube.

Joce640k Re:preventing officers from being able to deactiva (152 comments)

Power requirements go down a LOT if you're writing to RAM instead of flash memory and not displaying anything on a video screen.

eg. I've seen CMOS sensors that use less than 0.1W.

As noted, battery life would be a problem.

Writing to flash memory needs a surprising amount of electricity.

That depends on how easy it is to turn them on.

It doesn't have to be a fiddly little switch, it can be a great big button. Officers who use it every day will soon get used to hitting it whenever they go into action.

You could even automate it - turn them on if there's a loud sound, use an accelerometer to detect when and officer starts running/fighting, etc.

Obviously the "off" switch is a fiddly little button...

SanDisk Announces 4TB SSD, Plans For 8TB Next Year

Joce640k Re:Oh goody (264 comments)

Now you can pay $4000 for a drive that won't last 2 years! Yeah.. sign me up.

With capacity like this they could put in a RAID0 option which halves the capacity but increases the reliability by orders of magnitude. If corruption is detected you can grab the shadow copy, remap it somewhere else, mark the block as bad. The chances of two blocks failing at the exact same time is insignificant.

Why Microsoft Shouldn't Patch the XP Internet Explorer Flaw

Joce640k Re:Microsoft Opened Themselves Up for Lawsuits (345 comments)

Right now Windows XP is used on 1 in 4 computers (approx).

I bet you'd be the first in line to complain if Ford stopped supporting a model when it dropped below 1 in 4 of all cars on the road.

Ask Slashdot: How To Back Up Physical Data?

Joce640k Re:Old tech: xerox machine (245 comments)

Periodic copying, on a copier/xerox, of the contents of your wallet works well. Make sure you copy both sides of credit cards and such, as they have numbers to call for cancellation or replacement. You could even simply scan the contents, then encrypt and store it somewhere.

What is this "copier/xerox/scanner" you speak of? Are you also going to telefax the copy you made to the secure location?

The correct method is to place the document on a wooden table and photograph it with your cellphone.
