I remember the big hoohah when the "The Day After" was shown on TV in '83 and the school sent home a notice recommending not letting the kids watch it as it may traumatise them. I was in middle school at the time in Silicon Valley and there was definitely a fair bit of paranoia on the subject in the early '80s.

Of course that same year I was probably getting frowned upon for playing Gamma World or Paranoia during lunch and recess.

This is like assuming that all Olympic coaches have to be better than the champions that they produce.

The trick isn't knowing more than the students, but knowing how to maximise the students learning experience with appropriate suggestions and directional guidance.

Obviously there is a minimum level of skill/knowledge required, but there is a very wide scope where knowledge/experience/wisdom may not overlap between the student and teacher. It is up to the teacher to leverage this differential to push the student forward.

Problems pop up when the kids get arrogant and think they know far more than they really do. This usually leads to a disrespect between the teach/student. And for teachers that take this personally, it ends up becoming a play for power and control.

A bit more humility (either real or faked/learned) can go a long way.

Gotta love investors that shiver at a slowdown of the second derivative of the growth curve. Amazon is still growing and the growth is increasing, just not a fast enough increase of growth growing.

Amazon is a huge successful brand with multiple obvious methods of income from product retail to cloud services.

This seems like a bunch of investors not liking how Bezos is spending their money.

More likely is that 6 lines was enough general text where Richelieu could inevitably find subset that could be taken out of context from the whole where the inference would be contradictory or cross purpose to the original text.

For example:
One may write: The assumption that I would kill a man is preposterous.
After omissions of text at the beginning and end: I would kill a man.
The argument: Were these words not truly written by your own hand?
The result: An innocent man goes to the gallows.

The second amendment says nothing about defending yourself. It is simply about being free from harassment by government in owning and carrying 'arms'. It says nothing about using them against another person, and it seems to imply that it is for the purpose for maintaining a well regulated militia. The definition of 'arms' is intentionally generic so as to not exclude any particular type or category of 'armament'. Obviously it has been watered down by various States and case law, but not yet to the point of a blanket requirement that it only apply to a self-contained physical apparatus.

Beyond that, the concept of self defence is founded in common-law where it is deemed reasonable that you should be able to defend yourself against an attacker to prevent or minimise injury. Further to this, if it is legal (and reasonable) for you to be carrying a weapon (or tool) at the time, then using that weapon (or tool) for self defence is also a valid legal defence to prosecution of the self-defender.

However, you are correct in that retaliatory strikes are not self-defence. And whether or not a weapon or other tool is used to perpetrate the act is inconsequential to the fact that you then become the offending party.

Even more interesting would be if they start hybridizing drive with different SSD types. eg. 128GB of SLC high reliability high write count Flash combined with 1TB+ of ECC protected MLC/TLC storage. The older more static data migrates to the MLC/TLC storage, and the immediate data uses the SLC side of things where re-writes are far more common. This would of course be in addition to a capacitor or battery backed RAM cache.

A good controller could periodically scan the array in the background and rebuild any areas that start to accumulate errors. That way, drive failure becomes all about catastrophic hardware/controller failure rather than death by a thousand cuts as cells degrade.

This is similar to how high quality SDCards have small sections of high endurance (1M+ rewrites) EEPROM that is used for the internal remapping blocks and other fast changing blocks (eg. FAT).

I know it may sound a bit crass the way it's worded, but positive and negative reinforcement are extremely powerful motivation methods for both animals and people.

Reward charts are a long time proven method to keep kids motivated without using punishment. Punishment is also very useful, and like positive methods must be tailored for the recipient. Not all people respond the same to positive things, and punishment (or fear of it) is not always beneficially motivational.

Things like ClassDojo are a convenient 'digital' way of having a child 'carry around' a reward chart that can be seen/used by both parents and teachers. Functionally, it is quite effective.

However, as the summary points out, data mining and exposure of otherwise private information pertaining to a child is a problem. And something that needs to be addressed.

According to slashdot, copying data does not take anything away from the owner of the data, so there is no harm done.

Oh, wait... you mean it can harm them in other ways, like loss of market for the product, or loss of privacy? You don't say....

No, the prevailing ideology around here is that once data has been made public (ie. publication), it is no longer private and therefore cannot be 'taken' or 'stolen'. And that the action of copying this data doesn't necessarily cause a net harm to the original creator(s) of the work.

However, data that is private can be stolen and that is why this type of thing is frowned upon. Just because some 5 year old kid is in some private database does not mean that it is now free for everyman and his dog to mine or archive. Likewise to your private photo collection, your conversations in your living room, your bedside diary, etc.

TV images of when you ran through the town square naked? Not private either.
