It's more practical than a large weight and can be built anywhere unlike pumped hydro (which needs hilly terrain and space for a reservoir).

Not necessarily. It's possible to do pumped hydro in the ocean, pretty much anywhere on a continental shelf: pour a (BIG) cylinder of reinforced concrete, and pump water out of it.

It's hardly compact, though.

There's other options too, a flywheel for example could be more practical than lifting a weight (similar idea but much more compact).

A long time ago, there were some experimental buses in Sweden which used a specially-designed flywheel in a vacuum can, with magnetic bearings, to store energy rather than batteries. This is practical for a mobile system because the stored rotational energy can be used to directly drive generators.

In contrast to the steam-engine flywheels of days gone by, the Swedish bus flywheels were thicker toward the middle because of their reportedly extreme rotational speed.

Trouble is you need very large tanks of water, or to seperate them a long way. For instance a house might use 2 kWh overnight, that's about 7 MJ.

It isn't intended to be your primary source. Just as with other pumped systems, it's a supplement which stores during periods of excess and supplements during periods of shortage (or higher expense... some systems are now charging more for peak-period usage).

Pumped storage wasn't available UNTIL a couple of decades ago. I worked for an engineering company designing one and it was groundbreaking for its day.

I don't really care what he wrote. He remained a slave owner which says everything that needs to be said about his opinions on the matter. Jefferson was a remarkable man but also a very flawed one.

Spoken like someone who truly doesn't understand history, or even the recent past, for that matter.

30 years ago, if you told someone that gay marriage would be legal in many states, as likely as not they'd have looked at you like you were completely crazy.

And yet Washington and Jefferson owned slaves until the day they died so clearly they didn't really believe that even if they said so. Actions speak much louder than words. Yes I'm viewing it with modern day viewpoints but the fact remains that they had the choice to free their slaves and I'm quite sure they were aware of that at the time and chose against it.

I really have no choice but to say WHOOSH!

First off, they were products of their day. They weren't born today, and it is unrealistic to expect them to live like someone born today.

But second, and more important: they realized the political reality of their day. If they wanted a Constitution that states would ratify, they had to bow to the realities of their day. It's that simple.

And third, even more important than the first two: they created a country in which slavery could be abolished. They laid the groundwork.

If you read your history, you will learn that Jefferson abhorred slavery, but he thought that trying to free them all at once would lead to economic upheaval and disaster. While you may not like the fact that he kept them, he did have reason for thinking that way, and he may even have been right.

Comment Re:The of advantages of MIPSfpga over RISC-V (Score 1) 63

I'm familiar with the Microchip implementation. This is a 300-MHz-class 32-bit processor. Not particularly modern and not really fertile ground for R&D.

We did have two or three suggestions from commenters of open MIPS processor implementations, some of which are more modern. One uses a proprietary high-level HDL, which I haven't investigated.

The comments on that article are pretty interesting, most of them supporting the professor are along the lines of "These students absolutely are unprofessional! Who expects to keep their job after calling their boss a fucking moron?!"

They seem to miss the point that as a management class, these students expect to BE the boss, and they expect that there will be no repercussions when they tell their employee that they're a fucking moron.

Furthermore, now that these people will pass and become managers, I wouldn't be surprised if one of these people texts an employee telling them he is firing her because she wouldn't sleep with him, then when he loses his lawsuit and his money he'll go around telling everyone how an ugly bitch ruined his life.

Wordpress provides a large amount of hardening functions like this

...which are completely freaking worthless if they're turned off by default. 99.9% of users will never visit and study every available config option, and the other .1% will be wondering why it's not the default setting if it's so great.

Your post is like those who insist that MySQL has safe data settings for those who know how to enable them, while ignoring the fact that almost everyone uses the configuration as shipped. Unsafe by default is an insane and undefensible way to distribute software. In fact, I can't think of a good justification for ever allowing the unsafe values to be set.

All it takes is that the parents of such an asshole student are "important" because they donate money into the school's coffers, basically buying their precious little dud a degree.

And when told that you can't fail those students and kick them out of your class, you do what anyone clever would do, and bring some light to the problem by failing the entire class. Bravo! Goddamned brilliant, if you have integrity and are willing to deal with the consequences that is.
