Comment Re:And these breakers are connected to the network (Score 1) 29

Airgaps only make a grid unmanagable which would lead to more poweroutages. The answer isn't airgapping, it's actually knowing security.

If your idea of security is to simply airgap then you're going to fall victim by many other attack vectors.

Exactly. Have we all forgotten about Stuxnet already? For those who don't know, Stuxnet is a worm that attacked Iran's nuclear weapons facilities. Iran had their variable speed drives airgapped (standard Siemens SCADA system). And yet, Stuxnet crossed over, and managed to reprogram the drives in such a way that they failed prematurely (and part of Stuxnet is hiding the fact that it's mis-driving the drives so they'd fail).

Airgaps simply don't work anymore - there's too much informati0on that needs to be transferred between an airgapped network and the regular network that it's now a vulnerability to get the airgapped network infected.

I don't think what you describe is unique to Pixar, and we have similar inflexibility in the semiconductor industry.

It's not unique. It's because your company is run by managers who realize both the nature of the work (there are deadlines that are hard to move) and there will be periods where you're working extremely long hours. But they also realize the importance of family, so they invite your family to come over and join you during break periods so you don't get all bogged down in work.

For some companies, Pixar and many semiconductor ones, allowing unauthorized personnel even in "public" areas is quite a big deal (who knows what they may see or overhear). That they allow children and spouses to hang around is a really big deal - it shows the company cares about the well-being of its workers. Sure they're in a public area, bur even in a private cafeteria often sensitive things get discussed.

So no, it's not unusual, it's only unusual in that the company cares about its people, and knows that while the crunch time is unfortunately necessary and temporary, they also know that having family over for meals means a lot to the workers. Especially since security policy can easily demand that the family be stuck outside the main door.

Pixar was unique in Silicon Valley companies in that we had deadlines that could not move. The film had to be in theaters before Christmas, etc. I'd see employees families come to Pixar to have dinner with them. I took the technical director training but decided to stay in studio tools, first because Pixar needed better software more than they needed another TD, and second because of the crazy hours.

As Rei said: it is a solved problem, you build a road. This is a cheaper solution. That's what technology is after all, the ability to do things more efficiently.

Plus: who gets to decide what's "frivolous"? Certainly not you. Whatever people will pay the most for is the least frivolous, as there's no better objective measure of value.

No, but it is 51% of the transaction validation hardware, from which you earn block rewards and transaction fees. The rewards and fees are denominated in bitcoins, so it is in your self-interest to keep the value of a bitcoin high. Fucking around with the transaction history would destroy people's confidence in bitcoin, and they would flee for something else. Demand would drop, and so would the market price. Your expensive farm full of ASIC chips, which can do nothing but bitcoin hashing, is now earning tokens of no value.
