'Optical Fiber' Made Out of Thin Air

cellocgw how about secure transmission (115 comments)

Granted, I'm just another /.-er who never RTFAs, but I do have some experience w/ FO comms and free-air transmitters (of one wavelength or another).

So consider: the channeling lasers may disperse, but they carry no information beyond the existence of the channel and possibly the source and destination. The transmitted data packets do not disperse, so what you've got is the equivalent of a phased-array transmitter with zero sidelobes.

My mother's name wasn't Dave.

White House Approves Sonic Cannons For Atlantic Energy Exploration

cellocgw Re: Lol (272 comments)

A few years back, before Obama, one of my black friends said when we have the first black president they are gonna paint the White House black, and call it the "Black House."

In fact, the political comedian Dick Gregory said that about his own satirical run for president back around 1968 or so. When I'm president (c'mon, you guys gotta start campaigning for me!), I think I'll do the exterior in Jackson Pollock.

Strictly speaking, there is only "unique" and "non unique", but there's no "more unique."

True, but sadly, due to rampant misuse, there's no more "unique." :-)

Well, to be fair, Kissinger inside a Doonesbury strip said, "I'm sick and tired of people asking about human rights. What do you want: human rights or world peace?"

Amazon Is Testing a $10-Per-Month Ebook Service

cellocgw which 6E5 titles? (87 comments)

It's kinda like cable tv: 500 channels, of which 450 are QVC, 40 are rerun channels, and 10 are worth watching.

Similarly, plus its "affiliates" claim 100k books, but rather a lot of them are of extremely limited interest to anyone other than historians.

Amazon has roughly 33 million listings; even allowing for overlap between kindle, paperback, and hardcover (and audio), 600k is a rather small fraction of what's out there.

White House Punts On Petition To Allow Tesla Direct Sales

cellocgw Re:He cant or wont? (382 comments)

Meanwhile,today, if you can afford a $90,000 car, I doubt there are any real impediments to your making that purchase.

That's all very nice and snarky, but Tesla's got a Model E in design with a target sticker price of around $30k US. Wouldn't it be nice to fix the problem now, so in a couple years we don't have to order our Tesla-E via Amazon Prime?

Coming Soon(ish) From LG: Transparent, Rollup Display

cellocgw forget transparency, it's the rollup (64 comments)

If I could only get a 7 or 8-inch tablet with a screen that could be unrolled (and maybe unfolded) to say 16 by 10 inches, I'd be in techietoy heaven. No more squinting at tiny webpage displays, no more squinting at 6-point font displays of books,... you get the idea.

New Technology Uses Cellular Towers For Super-Accurate Weather Measurements

cellocgw Re:Military Applications (42 comments)

The military application is that it is rumoured to be able to detect stealth aircraft.

No rumor that. Dunno about cell towers, but it was shown pretty conclusively in the '90s that the "hole in the sky" caused when a stealth aircraft blocks FM radio signals can be seen. Depends of course on having a good FM sensor and a solid transmitter or two in the area.

India's National Informatics Centre Forged Google SSL Certificates

cellocgw Re:All about trust (107 comments)

The whole point of issuing certs is to be a trusted third party. No one is going accept a cert from them again.

Sounds like what we need is a cert-issuing protocol based on Bitcoin security. Everyone (plus or minus epsilon) trusts that Bitcoins can't be forged.

TSA Prohibits Taking Discharged Electronic Devices Onto Planes

cellocgw Re:Christmas is coming early this year (702 comments)

I don't see a problem showing a device is working as intended. If it can prevent even one bomb from going on a plane it's well worth it.
I don't see why people are getting bent out of shape about this. Take a chill pill people.

Dunno why I'm responding to a subhuman troll, but hey it's Monday, so:

First of all, it won't prevent any bombs from being brought onboard. How difficult do you think it is to show a working laptop which happens to have 500g of C4 wedged inside?
Second, it's an absurd abuse of reality, since as everyone and his brother already said, any device w/ dead battery -- or heaven forbid, some toy that only runs on AC and you didn't bring the adapter-- gets tagged as "dangerous terrorist thingie."
Third, it'll be cheaper to pay $10 million per person injured, let alone killed, by your fictional device-bomb than the direct and indirect cost of this screening program.

Finally, it'll take approximately negative 5 seconds for any potential bomber (of which there aren't any in the first place) to use some other gizmo to carry a bomb. Like a fake tin of sardines. Ooops, apologies to everyone who was going to bring a snack on board.

Cambridge Team Breaks Superconductor World Record

cellocgw Re:Shielding (73 comments)

I was looking at this issue before thinking something similar to the ways that ships have bars of iron fixed to them so that the bars decay before the hull. Its not an apple or apples comparison but the end goal is the same, save the ship/crew by sacrificing a small part

So you're saying we should wrap the spaceship in a layer of crew members to save the remaining crew from radiation? Maybe that explains the Reavers' actual reasons for their ship accoutrements.

An Army Medal For Coding In Perl

robocalls with a bucketfull of numbers

cellocgw cellocgw writes  |  about 8 months ago

cellocgw (617879) writes "Over the last few months, I've got multiple calls (on each of the numbers listed below), all with identical pitches selling the same home security system. These calls come thru despite my being on the "national do not call" list. I took a look at the FTC complaint page, but so far as I can tell it'd take me 4 pages' worth of form to report each number. What to do?

How about a new unit for data size?

cellocgw cellocgw writes  |  about 10 months ago

cellocgw (617879) writes "The explosion in file and memory capacity has led to a plethora of prefixes used for byte size: giga, pata, exa, and so on. Perhaps it's just time to add a "base unit" to the current bit, byte, and word appellations. Perhaps we could define a "Book" (abbreviation: Bk) as one gigabyte, and thus greatly simplify memory-naming requirements."

How the Republicans maintained control of the House

cellocgw cellocgw writes  |  about a year and a half ago

cellocgw writes "A statistician over at Fellows Statistics did some analysis to see what factors were most strongly correlated with disparities between popular vote (per state) and the ratio of Democrats/Republicans elected to the House of Representatives. No surprise that the party in control of redistricting ends up on top; or that in recent times, computer-aided Gerrymandering has helped the Republicans maximize the disparity between popular vote and elected seats."

Proposed: replace comment score with arachnid graphs

cellocgw cellocgw writes  |  more than 2 years ago

cellocgw writes "Everyone with a slashdot number under 10^8 knows that the "Score: 3(Funny)" probably has a dozen "informative" and "Troll" and "redundant" moderations that aren't visible. How about we plot an arachnid chart, displaying the current number of every possible rating category? That would provide an awful lot more info in a reasonable space, and there would not need to be a max score limit."

Holy Softbook Destruction, Batman!

cellocgw cellocgw writes  |  more than 3 years ago

cellocgw writes "This morning I went to a few of the many websites which feature the Quran (Koran). I loaded a bunch of webpages and downloaded a pdf copy of the book, then deleted the pdf as well as my browser cache. Does this count as destruction of a holy book? If not, where is the line drawn, seeing as destruction of mass-produced paperbacks apparently is a bad thing to do?"

Is a 9/80 work schedule a good thing?

cellocgw cellocgw writes  |  more than 5 years ago

cellocgw writes "My company is in the process of implementing a version of "9/80," a work schedule which squeezes 80 hours' labor time into 9 business days and provides every other Friday off. I was wondering how this has been implemented in other companies, and how it's worked out for other Slashdot readers. Is your system flexible? Do you find time to get personal stuff done during the week? Is Friday good for anything other than catching up on lost sleep? And perhaps most important, do your managers respect the off-Fridays or pull people in on a regular basis to handle "crises"?"

How to teach friends not to forward hoax email

cellocgw cellocgw writes  |  more than 5 years ago

cellocgw writes "I recently received the "your cell phone number is being given to telemarketers" hoax email from a not-very-technosavvy friend. I fear I reacted rather strongly, sending a reply that was a solid mix of Steve Ballmer and Richard Dawkins to all email addresses on the forwarding chain. While I did suggest they try fact-checking, and listed a bunch of sites like snopes and urbanlegend, I certainly wasn't very diplomatic. So: can you recommend a calm, respectful way to get these folks to learn not to pass along garbage stories?"

Sports injuries caused by breaking rules

cellocgw cellocgw writes  |  more than 6 years ago

cellocgw writes "Well, duhhh: a new study quoted in Science Daily says a large portion of sports-related injuries happen when a rule is broken. Even more amazing (not) is that the percentage of such injuries is far higher in soccer than volleyball. Who would have thought that contact sports were riskier than non-contact sports?"
