There is no red envelope or similiar notifications button, to see replies at a glance

Click the word "Slashdot" at the top left of each page to go to the home page, and your replies should be just below your username in a box at the top of the right column.

No way to even find old comments that slip off the relatively short comment list

I get a "Load More Comments" button at the bottom.

Comment: Statutory rape (Score 1) 200

by tepples (#49359269) Attached to: NZ Customs Wants Power To Require Passwords

But in the case of rape or murder, well, that will end family ties for a few decades.

For this purpose, would you consider "rape" to include sexual contact between an 18-year-old and a 17-year-old when the 17-year-old has presented fake ID? Or are you in the "save it for marriage to avoid accidental molestation convictions" camp?

Comment: I pledge allegiance to Jehovah God (Score 1) 260

How about Pledge of Allegiance — is that a "cohesive contract"

Members of some religious groups handle this by not saying the Pledge at all. They pledge allegiance only to god, or they say a parody pledge referencing a pyrotechnic accident in 1984:

I pledge allegiance to the flag,
Michael Jackson makes me gag.
Pepsi-Cola burned him up,
Now he's selling 7 UP.

Comment: Godwin on Godwin's law (Score 1) 200

by tepples (#49358909) Attached to: NZ Customs Wants Power To Require Passwords

In practice, the meaning of "Godwin's law" has grown from the original "later posts to threads about social topics invite more comparisons to the NSDAP" to "he who makes such a comparison loses the argument". Mike Godwin wrote about being surprised about how this law took root in popular culture: "I wanted folks who glibly compared someone else to Hitler or to Nazis to think a bit harder about the Holocaust."

That the thing about dark matter... it has a perfectly reasonable explanation (WIMPs). It's not that weird of a "thing".

Dark energy on the other hand, that's just WEIRD ;) It doesn't act like any "energy" as we know it, even though everything is clearly moving into a higher energy state. A question I've had for a while... if space itself is being inflated (or any sort of mathematically equivalent scenario) - everything inflating in all directions at all scales - wouldn't there be some sort of weak radiation signal from electrons expanding into a higher energy state due to dark energy and then collapsing back down? But I have trouble picturing how to reconcile an absolute, varying distance at the atomic scale with quantization of energy states, positions, etc...

Sure there is: add this to the CPDLC standard and make all of the hardware modifications needed to support it:

----
Message type: Revert flight plan and lock
Message arguments: TIME: the time of the flight plan to use
Message description: Revert to the flight plan that was active at TIME that had been approved by both ground control and the pilot; engage autopilot; and disable all pilot / copilot access to all systems. If there is no approved flight plan then the flight plan is to return to the nearest suitable airport in the most direct route possible.
----

Additional modifications: Make sure that the pilot can never disable datalink communications with ground by any means that ground wouldn't have time to respond to.

Result: Nobody is ever "remote controlling" the plane from the ground. A murderous / terrorist ground controller can't crash the plane, only make it autopilot itself on a previously approved or otherwise reasonable flight plan. A pilot behaving suspiciously can't crash the plane, as ground control will just engage the autopilot and lock them out. To abuse the system both ground and the pilot would have to agree on a suicidal flight plan.

Comment: ArrayList and StringBuilder use this (Score 1) 479

by tepples (#49354885) Attached to: No, It's Not Always Quicker To Do Things In Memory

I would realloc the buffer doubling the size each time it overflowed. This allocation strategy is simple, is bounded to 50% worst case overhead, and requires only log N reallocations for a maximum buffer size of N.

It also happens to be the policy used by Java's ArrayList and presumably by its StringBuilder.
