Comment Re:Totally false (Score 1) 252

There is bias voltage available on the second ring of a TRRS connector, as it is necessary for the condenser microphone used for wired headsets.

It's not much in terms of voltage or current availability, but it's plenty for numerous companies to have manufactured credit card readers with active electronics that are powered entirely by it.

What are you going on about?

You can stream Mozart in the Jungle for as little as $1.99 per episode, no Prime membership needed. Similarly with Game of Thrones and Orange is the New Black, though those cost a little more.

It seems very expensive to me, but if that's what you want to do, you can do it.

Comment KVM (Score 1) 166

It appears plain that Red Hat has spent plenty of money on virtualization with KVM and friends.

It is plain to me that KVM and friends work fine on every other distribution.

If my goal is a KVM host, why should I buy RHEL instead of just using it on some other distribution?

Some people (most people?) don't build.

I lived in a ancient (by US standards) 2-story rental with plaster interior walls with metal lathe, and concrete block exterior. With an unfinished basement , a detached garage, and a huge yard.

Primary router/AP was in the middle of the basement, attached to the ceiling, because it was easy and invisible. It didn't adequately cover the house, and as the modulation rate ratcheted down to cover the slower/farther-away clients the nearby fast clients suffered as well.

So I fixed it: Another AP (-ish, I'm a Tomato and OpenWRT fan) went upstairs on the 2nd floor, and I was fortunate to find an easy path from the basement for cabling. This also let a heavy user upstairs plug in directly instead of using Wifi, saving wireless bandwidth.

And then, the garage and back yard. I tinker with and work on stuff, so the garage was important for lots of reasons. And we had a great garden way out back, where we found Pandora to be important. An old WRT54G and some kind of freebie (to me) forgettable router-box that would run OpenWRT formed a client/AP solution, which covered both handily without cabling to the main house (which can mean death to gear when lightning happens, unless fiber or other electrical isolation).

I could've done all of this with WDS, and done it badly. Instead, I had a system with decent frequency allocations that simply worked. (This was all 2.4GHz.)

With newer ideas about self-configuring dual-band mesh (to which WDS barely applies), I would have been able to accomplish something functionally identical using one box in the basement, one box upstairs, and one or two well-placed boxes in the garage.

And zero wires.

Absolute performance would've been worse than my complicated scheme, but most folks' don't care about that: They just want Netflix, Youtube, Facebook and gaming to work, and do so reliably and properly, whereby ensuring that the pipe to the ISP remains the bottleneck instead of the local WLAN is the first step toward victory.

(Now, of course, cabled is true victory: I pre-ordered the Ethernet adapter for Chromecast the moment I saw the announcement, just to keep that fucker off of my WLAN -- even though it was twenty unobstructed feet from the AP. But it's not always practical to cable everything, especially if you don't own the place.)

Comment Re:Finally Ford see the future. (Score 1) 432

50 years ago, efficiency was shit -- as was power-to-weight ratio, and power-to-displacement ratio.

Modern engines are well ahead at every step of these games, including those from Mazda.

And nevermind that folks don't talk about bearings and rings and rebuilds anymore. It's just as possible to rebuild/refresh a new engine as it was one built 50 years ago when these terms were more common. It's just almost never necessary or desirable to do so, because things still tend to be working fine (or at least quite well) after a couple of hundred thousand miles of bad maintenance.

I looked briefly at that.

For years, I kept a USB drive on my keychain. Various styles. Their mounting systems always inevitably failed, and this usually left me without one until I replaced it or it was returned to me (which HAS happened, though I always nuke the data and restore from backup upon its return).

The ExtremKey seems cool, but has some problems. One, the business-end -- where the data is -- unscrews and is then left to freely disappear. The tailcap is cast rather than machined (unlike any cheap Maglight, ever), lending extra opportunity to munge the threads with repeated use. The mounting hole is tiny, and has very little material supporting it (as you noted).

But the biggest problem: It's big, so I'll be inclined to keep this on my keychain, which I wear on my beltloop, making all of the above even larger issues.

My answer for the past couple of years has been cheap, thin drives from PNY. The body is the same size of a normal USB A connector shell except for a (useless) plastic loop that I always cut off with a knife or a file.

I keep it in my wallet. It's safe there, or at least as safe as tons of way-more-important-to-me things. It's shock-mounted, being wrapped in leather. And it tends to stay as dry as I do (not that water is generally an issue for these things). And even if it falls apart (ie: the PCB slides out of the metal housing), I'll have all of the parts neatly contained in my wallet for recovery and/or repair.

It's also big enough for decent heat dissipation for lengthy writes.

The last one I bought was $10-ish at Wal-Mart of all places, and I forget if it was 32 or 64GB (and it really doesn't matter: either is very cheap, I think). Amazon has them for about $15, prime.

Zero complaints.
