Re: NSA-proof Euro cloud
Giving me a chance to mention one of my favorite quotations:
``There is no fortress so strong that money cannot take it.''
---attrib. Marcus Tullius Cicero (I can't find a reference to any work containing it, at least on the Internet.)
Yet again---shiny new tech is a step backward
The bottom line is circuit vs. packet switching. In a circuit, you have exclusive (modulo the NSA)-: access to the full bandwidth so long as you're connected. Result: 5x5 reception on both ends. Packet switching makes your access to bandwith a stochastic function. Result: jitter, dropouts, &c. Telephony was making clear progress from the 1880s to maybe the 1980s, and it's been steadily downhill since.
And don't get me started on cell phones---like radiotelephony in the forties. All I want is a way to hear and be heard clearly.
I'm obviously well into old farthood, hence the icon.
It's been too long since I took advanced statistics, so if someone with more recent knowledge could enlighten me I'd be appreciative.
How is 4.9 ± 2.6 meaningful? Offering a value to the nearest tenth when uncertainty is ~30 times higher is warped. Shouldn't it be 5 ± 3?
More fun, and better-looking in its field, but is the TR-3B really faster? Methinks not.
With all this knife knowledge coming out of the woodwork, could someone speak to sharpening serrated knives? I have a really nice bread knife that needs some attention. Do I just sharpen it as I would any other knife, figuring I'll hit the high points, and the valleys don't matter? Must I buy a new one?
Inquiring minds want to know.
Re: Ceramic knives?
A friend uses ceramic knives, and curiosity led me to check the edge with a jeweler's loupe. The wear process was chipping, with still-sharp bits between the chips. Looked to me as if it was turning itself into a serrated knive with a sharp, intermittent edge. I suspect it'll stay super sharp until most of the original edge is gone.
Can anyone who actually knows what they're talking about expand on this?
Note to webmaster: We really need an icon of someone talking through a hat.
Back in undergrad days, a friend of Swedish ancestry took a course titled Reading Swedish, Danish, and Norwegian*, the idea being that the written (not spoken) languages were close enough as to make it possible (in one semester). Seems he's grasping at straws to claim he doesn't understand the warrant.
Can anyone with real knowledge confirm or deny that this is the case?
* Extra credit: Why isn't Finnish on this list?
Schneier got there over a decade ago
This little exploint rang a bell, so I searched Bruce Schneier's website. And, sure enough, on July 15, 2000, he observed ``Unicode is just too complex to ever be secure. '' See https://www.schneier.com/crypto-gram-0007.html#9. Doesn't exactly warm the cockles of the paranoid's heart.
And in a similar vein: Fairphone.com
I've been watching with interest the development of Fairphone (http://www.fairphone.com/). They're actually manufacturing the hardware to put Android onto. They advertise that they're using fairly-sourced (reasonable wages for peons, no profits going to underwrite wars, ...) materials, the phone will be rootable, have two SIMs, and so forth. Only €325---cheap!
Disclaimer: I have no business or other interest in this device, other than that I lust for one, but don't live in the EU, which is their initial distribution area.
... a firm based in the United States.
Which means, of course, that Oz is inviting the NSA into their networks.
You do realize we're all in trouble now, no?
I expect at least a quarter of your readers immediately tried to surf to qwe54fggty.dyndns.biz, creating an extremely suspicious spike in activity.
Subhead: Central Monitoring System lacks algorithms, database and data
I suspect the NSA will be able to help out with that last.
Fairphone goes on sale to all---for sufficiently restrictive values of ``all''
They're only taking order from Europe. Here in the U.S., I'm SOL.
If it's simply a matter of shipping, I'll gladly pay the extra. (Would the VAT refund cover that?) On the other hand, if it's about meeting additional regulations, it may be a while.
In either case, I'd _really_ hate for them to miss the 5k goal because we outlanders can't buy one.
Not quite that bad
But how much less I haven't dug into. The description at the FedRAMP site says there's actually a third-party assessment of the service. Unfortunately, it's not a Federal third party, so watch out for winks and nudges.
They also claim there's an ongoing reassessment process, but unless failing to have a retest carries the same consequences as failing one, the budget for continuing oversight will be right up there with the budget for highway maintenance.
Robotic flying cars considered unlikely
``Highly reliable robotic takeoff, landing, cruise flight and traffic control certainly isn't a dream - the problems are actually easier than robotic ground cars, and they have pretty much been solved already.''
Sure, for objects separated by miles horizontally and thousands of feet vertically.
But that's not the situation for a genuine flying car. Take the road populace of New York City, elevate it all to a variety of altitudes, and watch your autopilots have nervous breakdowns. A population of flying cars in numbers comparable to what we have on the ground is such a difference in degree as to become a difference in kind. Ask any programmer scaling up a program from hundreds to hundreds of thousands of instances.
Someone speaks with forkéd tongue
Examining the eminent Mr Dabbs's 2010 interview with Features Exec, we find the exchange:
Q: Do you find press conferences, trips, parties and other events useful or an interruption?
A: They are always useful.
@Mrs B J Smegma: In the same location, we find him noting he was the first non-U.S. journo to test the original iMac, so 'twas not always thus.
Send it to Coventry
That is, partition your disk and set up experimental all by its lonesome. I run stable and unstable that way, and I'm about to install wheezy in a third partition.
Of course, this takes a reboot to change. Extra points if you install them on virtual machines. :-)
[For this one, Mr. Holmes is saying ``Elementary, my dear Watson''.]
Would that it were so.
I don't know what law the grandparent poster (AC) is referring to, but you only have to look at ACTA (http://en.wikipedia.org/wiki/ACTA) to see an example of the U.S. using its economic weight to force other countries to do the bidding of American corporations. For rampant privacy invasion, check the PNR (http://en.wikipedia.org/wiki/Passenger_Name_Record) history, in which the U.S. pressured the EU into sending passenger info to the TSA before the flight leaves. They ``promised'' it would be used only for anti-terrorist purposes, but they've reneged on that, and roughly the entire federal government now has access to the data.
So long as the U.S. packs sufficient clout to present a credible economic threat to its subject nations, we're all screwed. The way things are going, though, maybe the U.S. economy will weaken so much that no one cares anymore.
[Beer because that's what I'm drinking now. Maybe it'll help me feel better about all this.]
Why are they so damn' noisy?
It's all electronics and radio waves, but neither my computer nor my radio make that sort of a racket. Are the magnetic fields so strong that we're hearing the structure being warped out of shape? If so, I hope they have the framework inspected at least as often as an airliners. If not, what's going on?
Name that weapon
Don't look now, but David used a sling---in the picture you see him on the backswing, about to loose his secret weapon. A slingshot is a forked stick and elastic. I doubt even the Wrist Rocket* models are more powerful than a skillfully-wielded sling. (Of course, that's the down side: a sling takes a lot of practice to get good at.) Think of a slingshot as a very small bow, and a sling as an atlatl for rocks.
It's frighteningly easy to extract identities from supposedly-anonymous data sets. Some Univ. of Texas researchers showed it's fairly easy to take Netflix's anonymized preferences list, cross-index it with the IMDB, and identify a number of the subscribers (http://www.schneier.com/blog/archives/2007/12/anonymity_and_t_2.html). Given a 5-digit ZIP code, gender, and date of birth, you can identify over 85% of Americans (ibid). If you know where an American works and lives _to the census block_, you can establish identity almost 100% of the time (http://www.schneier.com/blog/archives/2009/05/on_the_anonymit.html).
Be _very_ suspicious of claims of anonymization. Schneier notes ``[A]nonymity systems shouldn't be fielded before being subjected to adversarial attacks.''
The ultimate evidence of prior usage
Guido should just drop a note to Tim O'Reilly, asking for an O'Reilly catalog from about 1995. Wouldn't having a book published about it strongly suggest Python's for real and antedates Veber?
LOL! That one's gone into my commonplace file.
Pay per byte
As mentioned above, bandwidth is (or should be) like water or electricity: I don't buy 100 kWh/mo for a fixed price, and have my fridge stop running on the 27th because I had my Xmas display up for the last couple of weeks.
I'm now using a web host that goes against the flow: I pay a certain amount per Mbyte of date transfer, and a certain amount per GB-month of storage, and guess what? It costs less than I can get anywhere else. It would be interesting if some gutsy telco would offer a similar deal for BW---I bet they'd clean up, especially once they started building out based on where they feel the pinch. They could even offer pay-per-byte and fixed chunk at the same time, and let the customers try it both ways.
Unfortunately, there's nothing resembling real competition in any telco/cable/bandwidth provider market I'm aware of, so I'm not holding my breath.
Re: I'm confused...
The deal is that since the galaxy is 212e6 ly away, what we're seeing is something that happened 212e6 years ago---at which time the galaxy was reasonably young. If we could wormhole over there now (whatever that means under general relativity) we'd be seeing an older galaxy, but until then we're stuck with what comes down from the sky.
In general, the further away a galaxy is, the younger it was at the time the light we're seeing now left it. That's why the boffins keep buying stronger telescopes to investigate the beginning of the universe. We see the far away stuff in a state closer to the Big Bang.
What do you do with it afterward?
How well does graphene degrade? What are its effects when it starts leaching out of landfills into the atmosphere / oceans / my backyard? Is this the Ice IX of the 21st century?

Let me get this straight...
The complaint that ``app store'' is generic is coming from the company that claims it has a trademark on ``windows''?
Do you prefer depending on the Pentagon, or the commies?
But you get your own guaranteed slot
Phone service between COs has been multiplexed for roughly ever (at least here in the US). But when you get a route through the network, that 3kHz is _yours_, all yours. So long as the network is up, you get sufficient bandwidth to actually recognize your caller's voice, and no dropouts when a packet gets lost.
The ``analog'' network puts all that in place before it puts your call through, and if it can't, you get the ``all trunks busy'' signal, rather than a connection you can't hear over.
They'll have to pry my landline from my cold, dead hands.... Unfortunately, AT&T is trying to obsolete them, without transferring the same QoS guarantees to the cell network. It warms my heart to walk past the CO and see that 15' wall of batteries inside. Take that, APC.
It's started already
Bruce Schneier (https://www.schneier.com/blog/archives/2012/12/china_now_block.html) reports that
``The "Great Firewall of China" is now able to detect and block encryption''
But what if they _can't_ inspect it?
@Fred Goldstein: ``The treaty allows governments to inspect the contents[....]''
If this is indeed true (I've downloaded the PDF, but not yet read it), how long do you think it would take the signatories to decree that the packets _must_ be inspectable---i.e., no encryption. Thus, what we USians have finally gotten the government out of (mostly) will see the world roaring back into.
So far, there's enough pushback here to prevent the feds from decrypting without a warrant (and maybe not even then, depending on what happens when the Supremes get a case claiming the contents of your brain are yours alone). But all the governments which would instantly say ``So sorry, but international treaty prohibits encryption'', and back it up by dropping any packets they can't read, would put paid to anything but steganography.
Re: Let's see if I've got this right...
@Roger Stenning: ``most of these conspiracy theory nuts come from the US, which has a VETO VOTE for pretty much anything''
Well, yes, that's exactly why they're worried. You see, the Trilateral Commission is in control of the U.S. government, and therefore can use the U.S.'s power over the UN to put in another order for a few Black Helicopters. When they've accumulated a sufficient supply....
Not just on your side of the pond
I didn't get to see him on TV, but his books riveted me, and focused my interest in astronomy. I wanted to be an astronomer until I found they don't actually look through the telescopes these days---it's still one of my main interests, though.
As for eccentricity, thanks to him I was the only kid on my block who knew what a blancmange was, decades before Monty Python.
He added much to my life, and I thank him for it.
Re: Someone has to write the assembler too
Ah, yes---my first job out of uni I wrote Z-80 assembly, and indeed maintained the assembler.
My favorite story from that job, though, came from writing FORTRAN on an HP 2100 mini, and maintaining the compiler (proprietary, but we did get the source). About when my program started getting large enough to be useful, the compile started crawling. I noticed the speed went way up when I didn't ask for a variable listing, so I poked around.
They were using a O(n**2) sort. I.e., it would make one full pass over the symbol table for every symbol it emitted.
Ah, the early days, when even econ majors wrote code.
Wishing into existence
"intellectual property is, among many other things, a fundamental property right that can't be wished away."
Fundamental property rights don't need legislation to create them. They get laws to punish those who violate them, but the government doesn't create my right to this ham sandwich---I did when I bought it.
``Intellectual property rights'' are a snare and a delusion. The U.S. Constitution recognizes copyright as a government-granted monopony. The Statute of Anne created it out of thin air. Despite the unfortunate name, copyright isn't a right, it's a monopoly on copying. Remember, theft applies to things the thief takes away from the owner: ham sandwiches, cash, Maseratis, &c. When an infringer copies a photo, the creator still has it. Nothing has been taken.
Much as I sympathize with Mr. Orlowski's anger at the ``freetards'', he loses much of my sympathy when he tries to claim the other extreme is true.
How could you forget Mesklin?
In _Mission of Gravity_, Hal Clement created Mesklin, a heavy-gravity, rapidly-rotating planet home to some intelligent and very strong millipedes. One of the interesting points is that he spent much more time working the physics of such a situation into his plots, and in very natural ways. Much better than the heavy planet = strong (humanoid) inhabitants (and nothing more) of Smith and Niven.
The defence is obvious..

When did people give up on sound quality?
They'll have to tear my landline from my cold, dead fingers.
I continually wonder, when I get cellphone calls from friends, why there isn't a vast uprising of subscribers demanding that all these electronic marvels provide little things like intelligibility or continuity. Certain of the worst offenders get me telling them to call back when they get a real phone connection.
``Because no affirmative action....''
`` is required by the website user to agree to the terms of a contract....''
That means the ruling only holds in cases where they say you have to agree, but don't make you click something to signify that you do. If they force you to click a button that says you've read the Ts & Cs, they may still have a chance. But I love the ``illusory'' characterization---couldn't have said it better meself.
Why not Ethiopian?
...I wondered. Until I got to Wikipedia's article (https://en.wikipedia.org/wiki/Languages_of_Ethiopia), and found there's no such language as ``Ethiopian''. The official language, Amharic, is spoken by about 30% of the citizens. Oromo is the most widely spoken, at around 34% and there are some 75 (90?) others in use. English is the language of secondary education, and the most-used foreign language.
I guess English was a reasonable choice.

Back when an inch was an inch
We had to repair the porch of our 1896 house---it was worn badly by a century of folks tramping in and out. So, it being made of 1" tongue & groove, the builder went out and bought some more. You can probably see this coming: looked at edge-on, the profile of the floor is now roughly
due to the fact that for modern timber, 1" nominal (isn't that a lovely phrase?) is actually 3/4". Shoulda shimmed it before installing, but who knew?
