Comment Two ideas on comment display from Reddit (Score 1) 393

Reddit has a system to base comment display and positioning on estimated asymptotic upvote rate, rather than raw scores or raw quotients. Randall Munroe from xkcd outlines the thinking here. This enables comments that are late to the party (like this one :) to gain traction and get displayed more prominently, if warranted by vote/moderation patterns.

Such quality estimators might be less important in a system with restrictive moderation caps a la Slashdot, but it illustrates a good point to consider in designing moderation systems.

Another thing Reddit does right is that "best" is not the only way to sort comments. Those who enjoy debate can choose to browse "controversial" posts instead, for instance.

In effect, Reddit recognizes that different readers have different preferences, and provides mechanisms for browsing and interaction that can accommodate these differences. This has the potential to reduce groupthink, or at least let several groups coexist and exchange information on a single site. Catering better to each individual may thus give a better site for all.

Silence, followed by small admissions, followed by admissions it's much worse that it appears, followed by more silence, followed by admissions that some members of the public may have been harmed, repeat.

Not to deny your point about reprehensible corporate self-preservation strategies, but in all fairness this also sounds exactly like the USSR disclosure history for the Chernobyl disaster.

Is this possibly a thing humans do, as individuals and in various organized groups?

Michigan Police Could Search Cell Phones During Traffic Stops 525

SonicSpike writes "The Michigan State Police have a high-tech mobile forensics device that can be used to extract information from cell phones belonging to motorists stopped for minor traffic violations. The American Civil Liberties Union (ACLU) of Michigan last Wednesday demanded that state officials stop stonewalling freedom of information requests for information on the program. A US Department of Justice test of the CelleBrite UFED used by Michigan police found the device could grab all of the photos and videos off of an iPhone within one-and-a-half minutes. The device works with 3000 different phone models and can even defeat password protections. 'Complete extraction of existing, hidden, and deleted phone data, including call history, text messages, contacts, images, and geotags,' a CelleBrite brochure explains regarding the device's capabilities." Popular Mechanics has a short conversation with a 4th Amendment lawyer about the practice of slurping cellphone data, too, though it's unclear if the Michigan police are actually using these devices to their full potential.

the government (...) is providing the loin's share of demand

As one of many disillusioned voters and citizens, I've become painfully aware that the government's loin demands a share of my rear end...

Isn't the drug situation a bit different from Anonymous?

One reason the war on drugs is ineffective is because monetary rewards for key dealers tend to increase to offset the effects of harsh prosecution. Simple supply and demand.

There is not necessarily as much money to be gained from anonymous cyberactivist/vigilante actions as from drugs. While this is no problem when risks are perceived as low, some players may drop out if punishments are increased, unless some other reward mechanism can be strengthened to offset the deterrence.

As an example, many file sharers I'm familiar with re-evaluated the situation and decided to stop sharing when the activity was criminalized. The threat of punishment certainly didn't kill off file sharing as a whole, but was at least partially effective in making it decline.

True, but if you could actually measure the mass of the butane molecule with enough precision, you would find that it is more massive than the constituent atoms alone.

I don't think this is quite right. The butane is actually less massive than the constituent atoms. That is why it sticks together, and why you don't have a heap of hydrogen and carbon atoms flying around instead. In order to dissolve the bound butane molecule into free atoms, energy must be added; this is the binding energy.

However, if you could measure the mass of butane molecule and the oxygen molecule(s) it reacted with before and after the reaction, you will find that mass has decreased. This decrease corresponds to the energy released by the burning, with a conversion ratio given by m=E/c2.
