Not to kick someone while they're down... but a security company screwing up their key rotation is not exactly a good sign.

Wrong thread?
ceequof··on [dead]
What an odd argument, at complete right angles to what I was talking about.

"Traumatic brain injuries are not the only kind of injuries. If it weren't for the fact that they result in death, they wouldn't really even be important."

If you feel I was minimizing the importance of sulfur pollution in comparison to carbon pollution, that is because I was. Carbon pollution is, in fact, more important.

Behold, data: http://i.imgur.com/t75zXYw.png

As much sulfur pollution, that is. (Mostly because ships burn bunker fuel:[1] the residue left over after you refine off the gasoline)

15 ships do not equal the carbon pollution of all the cars in the world.

ceequof··on Weave is kinda slow
In the terminal snippets, latency is specified in "us", which I'm guessing is µs, microseconds.

In the table, those latency numbers are specified in "ms". Also microseconds? Couldn't possibly be milliseconds, for two VMs that should only be a couple dozen metres away from each other, right?

ceequof··on Rapidly falling costs of battery packs for electric vehicles
AAA did it in 2011: http://newsroom.aaa.com/2011/07/ev-charging-statio/

"Level 3 charging" here means DC fast charging: 125 amps at 500 volts (depending on the vehicle)

ceequof··on Why technologists don't want to work at a government agency

  Get off your petastle.
Petastle, eh? If only you had access to dictionary dot com.
ceequof··on Homemade GPS Receiver
It was a surveillance aircraft, so it would need line of sight with the ground as well, which might require flying under cloud cover. Also, having a gyroscope component, I'm guessing that it would need to calibrate while stationary, on the runway.

MTCR is an informal agreement, not a treaty. Its provisions are actually implemented by laws in the member nations-- in the US, that's the International Traffic In Arms Regulations Act. (ITAR) ITAR Category XV, Section c:

  Global Positioning System (GPS) receiving equipment specifically 
  designed, modified or configured for military use; or GPS receiving 
  equipment with any of the following characteristics:
    1. Designed for encryption or decryption (e.g., Y-Code) of GPS 
       precise positioning service (PPS) signals;
    2. Designed for producing navigation results above 60,000 feet 
       altitude and at 1,000 knots velocity or greater;
So the US limit isn't even in metric units! Consulting my psychic powers, since I haven't bothered to dig up the laws for each member nation, I predict that each nation implements MTCR slightly differently, some using the word AND, some using the word OR. Since a GPS manufacturer wants to sell worldwide, they would have to use the strictest limits possible.

My crystal ball tells me that the judge would find your argument very amusing, but not substantive.

The SR-71 had an automated celestial navigation system that could get a lock in daylight: http://en.wikipedia.org/wiki/Lockheed_SR-71_Blackbird#Astro-...

(The big disadvantage is that it can't see through clouds, of course)

ceequof··on Homemade GPS Receiver
Incorrect.

The relevant agreement is the Missile Technology Control Regime, an informal partnership between 34 countries. http://en.wikipedia.org/wiki/Missile_Technology_Control_Regi...

Unlocked GPS receivers are classified as dual-use missile-related components under category II, item 11, section A.3: http://www.mtcr.info/english/MTCR-April2011-Technical-Annex....

  b. Designed or modified for airborne applications and having any of the following: 
    1. Capable of providing navigation information at speeds in excess of 600 m/s; 
    2. Employing decryption, designed or modified for military or 
    governmental services, to gain access to GNSS secure signal/data; or
    3. Being specially designed to employ anti-jam features (e.g. null steering 
    antenna or electronically steerable antenna) to function in an 
    environment of active or passive countermeasures.

ceequof··on Take Nothing, Leave Nothing: On being banned from the world’s most remote island
The British Empire also holds a similar tiny island in the Pacific: Pitcairn, population 67, inhabited by the descendants of the Mutiny on the Bounty: http://en.wikipedia.org/wiki/Mutiny_on_the_Bounty

It is mainly notable for a contentious rape trial in 2004: http://en.wikipedia.org/wiki/Pitcairn_sexual_assault_trial_o...

Long form Vanity Fair article, which is sufficiently similar to the OP that at first I thought I was rereading the same essay: http://www.vanityfair.com/news/2008/01/pitcairn200801

ceequof··on Amateur Radio in Play in Aftermath of Nepal Earthquake
KG7KGD here. I just bought a pair of cheap baofeng handheld dual band transceivers and programmed them with all the local repeaters and FRS/GPRS frequencies. Next step is to buy a dual band car radio and some solar panels.
ceequof··on AdBlock Plus defeats German publishers in court

  Is there ad blocker that only blocks the annoying ads, 
  not the ones that we deem "OK?"
Yes, it's called "AdBlock Plus". Read the article.
ceequof··on First 26 pages of Neal Stephenson's new novel Seveneves

  you're quoting a speculative paper.
Hawking radiation has never been directly observed, but it is generally presumed to exist.

  I haven't read the story extract, but I assume the plan 
  would be to bleed matter into the micro black hole to 
  maintain it.
Read the story. In context, the character is talking about how small a natural, primordial black hole can be. There is an obvious lower bound, due to Hawking radiation.

  I assume your point is that a GeV is a minuscule amount of 
  energy, which isn't going to push 130kT around at any speed.
Read the paper. That's the pseudotemperature of the event horizon. It's so hot that it's glowing largely in ultraenergetic gamma rays. The total power radiated by a .32 attometre black hole is 5,519 petawatts.

budu3: Note that this is a very non-idiomatic use of "derpy". Many other words would be more suitable.
ceequof··on First 26 pages of Neal Stephenson's new novel Seveneves
You are mistaken.

http://arxiv.org/abs/0908.1803v1 (See the table on page 15)

The lifespan of a 108,000 tonne black hole is ~350 hours. At that mass, its event horizon is .32 attometres across, and the Hawking radiation it emits is measured in gigaelectronvolts.

ceequof··on First 26 pages of Neal Stephenson's new novel Seveneves

     “Most black holes are formed when stars collapse,” Ivy said. 
     “But there’s a theory that some of them were created shortly 
     after the Big Bang. The universe was lumpy. Some of the lumps 
     might have been dense enough to undergo gravitational 
     collapse. They could form black holes that instead of 
     weighing what a star weighs could be a lot smaller.”
     “How small?”
     “I don’t think there’s a lower limit.”
Yes there is. Black holes lose mass by Hawking radiation: http://en.wikipedia.org/wiki/Hawking_radiation

A black hole smaller than 0.8% Earth masses loses more mass than it gains from the cosmic microwave background, and will eventually evaporate.

ceequof··on First 26 pages of Neal Stephenson's new novel Seveneves
It seems like my first knee-jerk impression of every Stephenson novel of the last decade has been "ugh, terrible", gradually replaced by a retrospective fondness after finishing it.

The first couple pages of Seveneves certainly does not impress, but maybe I'll like it better after reading the whole thing.

ceequof··on The Federal HTTPS-Only Standard: Necessary and Overdue
In somewhat related news, the .trust gTLD is HTTPS-only: https://whodoyou.trust/globalassets/documents/trust-technica... (As well as having a bucket of JS restrictions (no eval() can be used, apparently ever)

Adam Langley said something about enforcing secure TLD restrictions in Chrome a while ago, not sure if that ever got done.

ceequof··on Michigan Micro Mote – World's Smallest Computer
Ehhh. Marusek makes several rather large conceptual leaps in order to make his plot hang together: notably, both human clones and intelligent machines have no civil rights, at all, to the point that either can be killed at the will of their owners.

Most ludicrously, there's no hint of political opposition or a protest movement. At no point does any character say anything like "Hey, wait, maybe clones are humans too?" or "Maybe sentient machines should have rights?"

ceequof··on The 500-mile email (2002)
Writing stories for a technical audience is tricky. I've been doing it for going on 10 years now, and I'm still not very good at it.

A critical rule, however, is to omit detail, (a reader is unlikely to question an explanation they make up themselves) and most importantly, to omit details you know to be wrong. (It is impossible to nitpick a statement that is never said)

  An odd feature of our campus network at the time was that it was 100%
  switched.  An outgoing packet wouldn't incur a router delay until hitting
  the POP and reaching a router on the far side.  So time to connect to a
  lightly-loaded remote host on a nearby network would actually largely be
  governed by the speed of light distance to the destination rather than by
  incidental router delays.
He knew this was largely wrong, and didn't really improve the story, yet he said it anyway. It should have been summarized in a single sentence, leaving out all the problematic assertions that the slashdot trolls leaped on.
ceequof··on High performance HTML

  Use <em> and <strong> rather than <i> and <b>: <em> and 
  <strong> add meaning, not styling hints.
Strong disagree. What actual information does <em> provide over <i>?

What a pointless bubble chart. If you graph the number of test takers, then of course the states with the largest population (CA, TX) will have the largest bubbles.

ceequof··on Auto Racing Becomes a Favorite Hobby for Tech Elite

  At some point during every conversation I had with a tech guy who 
  is interested in racing, there would come an awkward moment in 
  which he would ask me not to paint him as an extravagant, sexist 
  cretin. Mr. Schachter told me, “Try to tone down the rich guy 
  hobby thing.”
Too late.

Note that the arduino.cc store is out of stock of pretty much everything, which makes sense if Arduino Srl is no longer manufacturing anything for them: http://store.arduino.cc/category/11

Additionally, tinkerkit.com (Arduino LLC's line of branded sensors for Arduino boards) has been down for at least a year now, which sucks, since that's where all the example code and datasheets are kept. We've seen sales for those drop through the floor.

The legal battle seems to have significantly impacted operations at Ardunio LLC, to the point that they're not really a functioning company anymore.
