Remember Alice?

I always thought it was "And we thought one big pile is better than two little piles, so rather than bring that one up we decided to throw ours down"

Re: Would you allow your website to serve ads that you would be held responsible for ?

The difference with Print advertising and Web based advertising is rather significant.

1. Print ads don't make you read the ad before viewing the content

2. Print ads don't harvest and phone home metrics on where you have been and what you have been doing

3. Print ads are required to conform to an ethical standard set by the relevant media authority

4. Print ads are traceable to their creators

5. Print ads don't contain malware intended to back door or hold your files to ransom

6. Print ads don't try to scam you with fake errors or issues trying to get you to pay for bogus support you never needed.

In my opinion the more like Prind ads that online advertising becomes the better. If Google is forcing standards and ethics on advertisers then great, about time someone did

Re: 100Mbps funny joke

Working in the IT service department of a telco who provides NBN service, it is my understanding that when a Fixed Wireless site is deployed it gets a basic allocation of bandwidth by NBN Co. Its not until enough customers on that site start to complain about poor performance that they come back afterwards and tune the bandwidth allocation.

So, it doesn't matter how many different ISPs you try, it's NBN Co and the FW Site that are the issue. Your only recourse is to complain loudly and often, and get as many people in your area on the same FW service to do the same.

Re: Astrophysicists think

How to stop?

Travel with enough fuel for conventional or ION engines to slow you down and manuver at the destination and use the light sail and FRB's to get you on the way there..

Re: drivers?

@DanceMan It was probably off so the tool could do some circle work

Re: "looking at the device for confirmation that it's working"

Yeah, I have an 865 myself. Most definitely full IOS.. Great little router, really helped cutting my teeth on CISCO config. Now I have the most complicated home network ever... (two fully managed switches, two routers, and House LAN, WIFI and Shed LAN on seperate subnets with full routing and access control/QoS)

You know what they say about assumption

@Charles 9

If they couldn't get basic network security to work I wouldn't assume they have an idea about public/private key security on a USB stick.

Re: British Summer Time

Quite possible it's Gamma Rays striking the CCD you see these artifacts on the raw CCD images on pretty much every spacecraft, they typically get removed in post processing before press release. The fact that the bright "Tan" coloured one in the bottom right is a horizontal smudge rather than a round blob indicates this to me. Gamma Rays are extremely directional and Stars are blobs.

Rounding Error

You gotta love compounded rounding errors.

Re: It's been tried before...

@JeffyPoooh

Pooh Pooh To You JeffyPoooh.

SpaceX isn't a government operation. It's a private company with in house manufacturing and is focused on inexpensive space access for a profit.

It's not some government pork barrel where every company is out to milk it for all the cash it can like the Space Shuttle program was.

Therefore your argument is invalid.

Re: Make your minds up...

I thought Apple had the design patent on a rectangle with rounded corners and Samsung had a patent on a circle with flat sides?

Must be wrong, oh well.

Re: Daft Government

I have had a test motor over pressurize and blow the nozzle out the end. Very loud. While I do agree in the wrong hands you could do some damage, it doesn't warrant the restrictions placed on it.

Re: SSD?

Yes, it still matters quite a lot. While SSDs are faster than spinning rust drives, RAM still blows it away by an order of magnitude at least.

These read speed figures for media are rather general

Cheap USB2 Flash Drive: 5mb/sec

7200 RPM SATA HDD: 120mb/sec

SSD: 550mb/sec

DDR3 RAM: 12,500mb/sec

So from that you can see how much faster your database would run with your tabled cached in RAM.

That being said, at $28k per core I don't give two shits how fast my database runs, you shouldn't have to pay that much for what should be a basic feature of any database

Re: Not foolproof

Definite side channel attack vector here. If the NSA can deduce RSA private keys from the silent squeals of a CPU then they can read documents by the sound of the keystrokes. I can actually remember they have developed this for PC keyboards so adapting this to retro tech would be trivial.

Perhaps the rest of the world should just file an international class action lawsuit against the US/English/Any other Cooperating government on behalf of the rest of the world

Re: Chasing rainbows

Why waste fuel for nothing?

Sure you need extra fuel that could be used to launch additional mass into orbit, but the reality of launching rockets is... Fuel is Cheap! it's the launch hardware that is not. If you spend a little extra on fuel to save a lot on hardware your ahead.

Re: Yes but what about supply voltage to each layer..

No, the power supply for each layer is done with conventional wire bonding, which for a few power wires around the edge of the die. The power wires can be done during the placement and bonding of each wafer.

The website has diagrams of how this works, they place the base die, put a layer of glue, align the next die on top, bond the power wires, put a layer of glue which encapsulates the power wires, places the next die, etc.

The upside of this approach is that there are only a few power wires per die (dependent on power consumption) which are bonded using existing low cost reliable technology. You aren't trying to make hundreds or thousands of connections between each layer using a new and extremely precise technology which increases manufacturing costs.

I can see a potential side-channel attack to this though.. what is the possibility of reading the inter-layer pulses externally to the chip?

Re: Can't wait to not buy this one!

My point being, those people who do wear watches, especially the "Flash and Expensive" ones, want a watch that is precision crafted, engineered by the best watchmakers the world has to offer, they are willing to spend 6 figures on a quality timepiece. They are going to look at a low 3-figure iWatch and wonder what kind of piece of shit that is.

The regular joe has a smartphone, if they have a watch its comfortable and practical, and in a woman's case, its usually dainty too. no matter what, Apple is going to be extremely hard pressed to fit a LiPo, cpu, ram, bluetooth, digitizer, piezio, lcd and charger all into the size of a practical watch.

Re: Integration

@MJI

No, never on the UK Motorway. I have driven around Los Angeles though. But being an antipodean the worst I usually have to deal with is Kangaroos jumping out at me in the middle of the night on a Motorcycle, and Melbourne Taxi Drivers.

Serious Application

I got the joke ;-) but...

A serious practical application would be additional chest space for additional chest-mounted components, or mounting counter-weights further forward in order to balance the battery pack on it's back.

Re: He'd be a fool to go and Germany would be a fool to ask

@AC-Nutter

If ZPE, Anti-Grav and FTL drives existed it doesn't matter how big your corporation is and how oil dependant it is you couldn't keep a lid on those kind of discoveries. The day an oil company gets ZPE is the day it becomes a power company, they could provide power for the entire planet for cents per megawatt and and it's 100% pure profit, they would become the richest company on the planet.
