I think the power company just wants to add "blockchain" to their name so the execs can cash out, but my quick back-of-napkin math makes me think it might actually work if they can fully sell it out. Assuming a 100MW plant, it would take US$25-40 million to get up and running, which would require $500/year/kW in rent for a 12-month payback, which equates to a US$0.05/kWh electricity savings to make it worthwhile.
But it seems like a lot of risk for something 12 months out before generating cash flow that is already a bubble.
But there is no way to plug the analog hole. You can still take a screenshot... it might need to be from another device, but it is there.
But, one thing works in its favor-- verification. If I have a screenshot of a document there is no way for me to prove its authenticity. Without some kind of verification means, much information loses its value.
A janitor might be able to get into a SCIF room undetected, but they would have difficulty removing any information from said room. Not entirely sure how they would get the malware into the room without leaving behind a USB key though.
In fairness, if you are looking at 10 bits per second, that gives you 5 or 6 cycles to modulate each bit over. That is going to be tough for (common) DC capacitors to filter out effectively, although the battery capacitance may still be in play. The rectifier should respond to a drop in DC voltage within a quarter-cycle. The AC filter capacitors won't see this at all, since they will only buffer a quarter-cycle.
What likely would impact it though is having enough PWM loads on the line and your power supply as a very minor component of load. At worst, you would be forced to use a lot of bits for error correction, but in all likelihood you would not be able to see the attack at the main service panel.
No, so they can switch to their A-series processors in Macs without having to go through compatibility for 32-bit.
I think I still have a very small arsenal of tools that are 32-bit only from 2005(?) when the first intel Macs came out. Personally not nearly as big of a deal for me as them phasing out 32-bit apps for the iPad.
More fundamentally to me is the issue that said car should not drive straight into a wall at full speed without trying to slow down.
There is plenty of blame to go around-- victim, Tesla, Caltrans for starters. Each of them screwed up on at least two levels. Tesla likely needs some kind of way for drivers to flag a spot where the autopilot screwed up, so they can gather data and investigate, because the victim was aware of issues at this location and tried to address it with Tesla in (apparently) multiple occasions to no avail.
What blows my frigging mind though is that the car will drive into a stationary object with high contrast safety striping without attempting to brake. Are they trying to determine approach speed based on visual sensors only that were blinded? Their "neural net" doesn't seem to be learning some important lessons quickly enough.
Mandated replacement of 14/3 NM every 25 years? Is that Canada specific? (Do you have the arc-fault circuit breaker requirement for residential that the US has?)
The problem with this concept since I first heard about it 7-10 years ago is it requires a low (opportunity) cost of power from solar 11am-1pm and vehicles that are plugged in, plus the same stipulation from (solar) 5-7pm. The first window often has people out at lunch (and/or parked at work where the charging cost will be higher), and the second window is at the time people are driving home from work or picking up the kids.
The only real opportunity I see is randomly when there is high wind energy nights and weekends driving costs down. These cases are exactly where large battery systems at the wind turbines are optimal-- doing the arbitrage local to generation and maximizing your revenue.
For emeregency backup I get it, and if your car never goes anywhere I can understand (telecommuting), but a powerwall seems like a much better tool unless all-day charging at work is free.
80/20 rule. 20% of the investment gets you 80% of the outcome.
Hidden inefficiency. Opportunities for improvement are masked by corporate process or culture.
Cloud services such as Salesforce provide a quick solution for management without the IT hassles. (But at price points significantly higher than doing it internally.)
IT's hands are tied by their vendors.
People don't understand just how much time some things take, especially on one-off things.
Crapware like Skype for Business is "good enough" and "free" (included), choking out other projects
Management is out of touch with where the IT opportunities are for improving systems. Without an advocate, it just looks like throwing money in a hole.
Think of them as a major us employer and energy consumer. They are less focused on a product in this space and more on the nature of the grid. Almost a more conservative approach than Tesla.
They also have a corporate history in understanding the botched deregulation of the California energy market and want to be able to better manage costs.
The only way clean energy does not make sense as a national grid objective is if the fuel is practically free, and you need significant multi-week storage capacity locally. Battery economics plus improved transmission capacity are likely to marginalized those benefits.
That can be really hard to make work, even for smaller organizations. There are real reasons why you have a holding company beyond liability protection that are quite difficult to avoid. Operations in multiple states is an easy one, but there are regulatory barriers in many industries that require a firewall between groups which are difficult to achieve without separate corporate structures. It can also make it hard to spin off or acquire another line of business.
Only if CenturyLink actively manages their subsidiaries day-to-day operation do they pierce the veil (or whatever the term is) of the subsidiary arrangement. We have CenturyLink, nee Level 3, nee TW Telecom for our office fiber. The only communication I have that says CenturyLink is the announcement of the merger.
That said, the announcement says:
I am very excited to share with you that CenturyLink and Level 3 are now one combined company. This means that you now have access to one of the largest global networks with more than approximately 450,000 fiber route miles and approximately 360,000 international transport miles. Paired with our SDN solutions and IT services, CenturyLink now provides one of the most comprehensive digital service portfolios available today.
Monetezation is not a right granted by the constitution. When using a 3rd party platform for hosting and monetizing your content, you are reasonably at their whims. Pick a different hosting platform, pick a different advertising platform, and do your crazy batshit stuff on your own dime.
Youtube is for puppies. No, wait... that is Instagram.
98% of Iranians in Iran do, but most immigrants here from Iran seem to identify themselves as Persians and only about half are Muslim from what I see... but I know a bunch of Z's so my perspective might be skewed.
That is a completely ignorant, revisionist account of what happened. It always took at least a couple generations for people to integrate, prior to which they stayed primarily with their “own kind,” and went into jobs held by the same group.
Post tensioning is a bit of an art, especially on a non-redundant structure. I would think for a bridge with traffic running below they would be slowly tensioning the system in increments following the load path.
Partially answering my own question, looks like the accident was on the southbound 101 at the 85 split. From Google street view, it looks like the k-rail is painted white just before the crash attenuator on both the left lane and the left exit ramp; north of this location the k-rail is bare concrete.
I wonder if this is another one of the Florida scenarios where the car reacts incorrectly to the visual information.
Afraid Tesla is going to lose some serious money on this one.
I don't understand why it even would run into the barrier... it wasn't in the lane of traffic. Is the barrier for a left exit? Late attempt at taking the exit?
Also curious about the accident two weeks earlier in the same location that compressed the crush barrier... seems odd.
I agree with you 100%. I keep trying to get people at work to just use the gmail webmail, but the lack of real folders kills them.
It really creates an incentive to drop gmail and switch email to o365. If Skype for Business wasn't such complete crap as a webex replacement, Microsoft would be unstoppable.
Not always as easy as one might think. For engineering classes (as an example), they might only be offered once per year and required for graduation. I had architectural studios that were half-days three days per week (plus every other hour in your life to meet deadlines), making scheduling nearly impossible.

Well, if you want it to work, try an air-compressor-driven (with a large reservoir) expander turbine generating power for the power supply.
Might be more effective to just put a larger DC bus capacitor in the PSU though.
In fairness, if you are looking at 10 bits per second, that gives you 5 or 6 cycles to modulate each bit over. That is going to be tough for (common) DC capacitors to filter out effectively, although the battery capacitance may still be in play.

Thanks— would be interesting to see how many big reports they got for that location...

Knob and tube wiring! What a joy. Well, you couldn't have an EV there anyway.

Close, but some actions like archiving old data and nested folders don’t work cleanly.
Depends on the cause of the crack...

Maybe they set the "final" tension all at once?
