South Korean Power Plants To Conduct Cyber-Attack Drills Following Hack

cellocgw WCPGW (24 comments)

That's my first reaction: it's one thing to set up a virtual environment and pen-test it; rather another to test systems which are currently making sure nuclear plants are running properly and fully failsafed.
Maybe I'm just paranoid 'cause I'm reading "Wolves eat Dogs," but I sure hope they don't test on an operational plant.

Geoengineered Climate Cooling With Microbubbles

cellocgw Re:Even simpler (113 comments)

Drive less. Ban incandescent light bulbs. Recycle more. Eat a little less meat. Turn down the heat. Turn up the AC. All which can be done with existing technology.

In order:
1) How? Not possible without fixing public transit.
2) Dead wrong. Historically, every single advance in lighting (cheaper better etc) has led to more lights being on longer.
3) Recycle is the lamest of the 3Rs: "re-use, repurpose, recycle". Try at least to start at the top?
4) Or, eat more Long Pig :-)
5) Maybe, or just stop building noninsulated houses and living in extreme weather locations.

More likely IMHO is that some sort of implantable slow-release reservoir system will be developed. Now you're down to surgery maybe once a year if all goes well.

How One Man Changed the Ecology of the Great Lakes With Salmon

cellocgw Re:Wrong conclusion: not "unintended consequences" (118 comments)

Clearly you've just proved "spontaneous generation" exists. :-).

I would recommend that you reword your statement to "...were never intentionally stocked..." . It's quite possible that some species (or their larvae) hitchhiked on boats (as shellfish have been demonstrated to do).

Which Programming Language Pays the Best? Probably Python

cellocgw from Economics-land (277 comments)

"Past performance is no guarantee of future returns."

Learn as many languages as you can/want and try to find employers who recognize that adaptibility is much more valuable than existing capability with a specific tool.

Now where are all those $250k jobs requiring R ? :-)

Thanks for the correction. I agree that the term "IR" is used for rather a wide range of wavelengths.

Scientists Develop "Paint" To Help Cool the Planet

cellocgw Re:Yes... (145 comments)

I don't mind when people state clearly that they don't really understand the absorption & radiation equations, but it does kinda piss me off when these same people pontificate as though they did.

Here's how this new microlayer thing works:

First, it's highly reflective in the visible. That keeps a lot of energy from every entering (and being absorbed in) the building.
Second, it's highly absorptive in the IR. Due to the reciprocity laws, this means it's also highly emissive in the IR (and btw it's also NOT emissive in the visible since it's reflective there), but that doesn't matter. Why? Because the Black Body radiation laws show that the radiative emissions for objects in the 250 K to 350 K range, which pretty much covers buildings, people, etc., are very high in the IR and almost nonexistent in the visible range.

What this means is that most solar input energy is reflected away and simultaneously lots of local thermal energy is emitted away. win-win (at least if you like it cool).

Attack of the One-Letter Programming Languages

Yeah, I generally google for "CRAN R" or "bioconductor R" to narrow down the field a bit.

Or you could just skim StackOverflow for the "R" tag.

Internet Voting Hack Alters PDF Ballots In Transmission

cellocgw Re:ssh / scp / https maybe? (148 comments)

Out of the hundreds of millions of votes cast over that past 14 years they've found less than 30 cases if in-person voting fraud which is a fraud rate of less than 0.00001%. Voter ID is just a solution looking for a problem.

If only that last sentence were true. VoterID is a solution to a major problem: getting rid of people who don't vote Republican. If you think the whole megillah was set up with actual fraud-protection in mind, you're seriously naive.

Education Chief Should Know About PLATO and the History of Online CS Education

cellocgw warning: nanny-state comment (134 comments)

Seems to me that kids who want to learn to hack around with a computer can quite well do so on their own, thank you. No need for some set of lessons, be they gov't-approved or not.

I mean, really: at the very worst, 10 minutes with a search engine, the term " introduction and tutorial for $LANGUAGE" or Stackoverflow should get anyone capable of comprehending what programming is in the first place off and running.

This story is exactly why I've encapsulated my self-notes and comments in c-code-style markings: /*this is a note to myself */

It's trivial to skim a document for the existence of such markups. Yeah, it takes a little-self-discipline while writing, but it sure pays off.

robocalls with a bucketfull of numbers

cellocgw cellocgw writes  |  1 year,29 days

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 a year 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  |  more than 2 years 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 4 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 6 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 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?"
