About the letting in employees, what about adding facial recognition?

It’s good that Google is so well secure, given the many things that rely on it

NetApp sells its ecosystem with "5 9s uptime". 

That is, the server network is GUARANTEED to be up 99.999% of the time.


Downing the cluster in such a catastrophic manner is *VERY* hard to do, unless you know *EXACTLY what you are doing.  AND, the only way to get that kind of administrative control, is to be on-site.

Combined with proper disaster recovery industry practices (redundant DR sites), Permanently destroying that data is going to be an onerous task, unless you enact a spy-movie like plot, like I outlined.

(even then, you will have to contend with tape backups in warehouses.)

Is bog-standard WD-40 safe to use on bike chains as a degreaser? I know it's quite good at that, but I'm also concerned that the whole "water dispersant" part will cause rust to form on the iron chains and cause further damage. I know there's like, specialized degreaser variants of WD-40, but all my local hardware store's got is just WD-40, so I bought that since I couldn't find anything labelled "degreaser" or anything close to that.

To put it into context, I want to re-lubricate my bike chains. It's not because it's squeaking or anything, but I figured since that my pedals were squeaking when I apply force on them, I may as well do that too. I read online that one of the steps to doing that is to remove the existing lubricant with a degreaser. I'm asking if WD-40 is a suitable degreaser. It's not a lubricant and should never be used as such, I know that much. If not, please suggest alternatives.

The on,y thing I know about WD 40 is that in the future it’s probably used as currency among bots (( visit the Warped 2 thread if the reference is lost)) but seriously this is the second time I’ve heard of it, the first time was from there

WD-40 is a lubricant often used for gearboxes and things like that.

If it moves and it shouldn't: duct tape

If it doesn't move and it should: WD40

The whole point of WD-40 is to prevent rust, among other things. So i think you misunderstand what the term water-dispersant means. It's not something that will cause water to build up, spread or become trapped. The point is that WD-40 has low viscosity, so it displaces moisture in places that regular grease or oil can't penetrate, thus preventing moisture build up.

Is WD-40® Multi-Use Product a lubricant?

Yes. While the “W-D” in WD-40 stands for Water Displacement, WD-40 Multi-Use Product is a unique, special blend of lubricants. The product’s formulation also contains anti-corrosion agents and ingredients for penetration, water displacement and soil removal.
...
While this may vary depending on the application, WD-40® Multi-Use Product remains effective even after it appears to dry. The corrosion and rust protection ingredients remain adhered to the surface. External conditions may require additional applications of the product for maximum protection.

Oh hey I used to be a bicycle mechanic, guess I still am a bit.  Yeah, it's perfectly safe.  My dad and I used it on rusty chains to get them mobile (doesn't help with any chain stretching or cog wear, but not everybody can just buy a new chain).  It's not much of a preventative like a proper teflon-based bicycle lube, but it doesn't hurt anything and doesn't seem to stick around in significant amounts.

Is there a standard notation for writing what gear you're on for a bicycle? My bike, for instance, has 3 gears on the left shifter, and 7 gears on the right, for a total of 21 speeds (though I can't imagine why you'd want to use all of them). How would I write that I'm in "left" (at the pedals) gear 2 and "right" (at the rear wheel) gear 5? Is it as simple as writing "2/5"?

I probably sound dumb or something, I don't know my bike terms.

[McTraveller]

To be imprecise, bigger gears in the front are higher-numbered gears and smaller gears in the back are higher-numbered gears.  This is because your "highest gear" is largest gear in the front and smallest gear in the back, and the "lowest gear" is the smallest gear in the front and largest gear in the back.

To be precise you would need to know the teeth in each gear, since "21 speed" doesn't have a universal meaning.  So you would say "I'm in 48:18" or "I'm in 36:22" or whatever.

For example, my bike has front gears with 48/38/28 teeth, and the rear has 7 gears that range from 11 to 34 teeth: 11, 13, 15, 18, 22, 28, 34.

[methylatedspirit]

That's (48:18, 36:22, and so on) the gear ratio, isn't it?

EDIT: I see text engraved on the gears themselves (16T NH, 18T NH, 20T NG, 22T NH, 24T NI, VIA from smallest readable to biggest on the rear gears). Are the numbers with T after them the number of teeth? Do the letters after that (NH, NG, NI...) mean anything?

EDIT 2: I've counted the number of teeth on the sets of gears. If I'm understanding it right, rear: (1..7) -> (14, 16, 18, 20, 22, 24, 26), front: (1..3) -> (54, 34, 24).

So "2/5" as read from the shifters on my bike would be "22:34"?

[Ulfarr]

Since you'll be using it on a bicycle's chain, I think standard WD40 would be just fine. The specialized degreaser/lubricant variants are intented for motorcycle use because their chains are usualy "self lubricated" meaning they have some lube sealed between the links (O-rings, X- rings, Z-rings) and standard wd40 can damage them.

Does there exist any way on any sound chip to do sample playback/polyphony using its noise channel by somehow manipulating its RNG to make it output the sounds you want? Considering how far people have broken, say, the SID chip, I'm surprised that they haven't yet messed with the noise channels to do their bidding. I know that there's more practical ways to achieve sample playback/polyphony (from what I know, 6581 SID has master volume screwery, ZX Spectrum beeper has PWM), so I'm just asking if it's even theoretically possible.

Is telling kids that Santa Claus is real primarily an American thing? Aka have many Brits and Aussies etc here been brought into the Santa Lie^TM when they were young?

I'm a Kiwi and my parents didn't go for any of that, although my sample size is too small to tell whether or not that's par for the course around here. Given how much America dominates media, television etc I'm wondering if it's all that widespread or if it's only something they do.
