Despite the title there are a lot of restrictions from the chinese side as well:

>Beijing in March said domestic and foreign airlines could operate no more than one weekly flight between China and any given country

>The Department of Transportation said the March order had effectively banned US airlines

>In recent weeks, China has moved to loosen restrictions on charter flights from some countries but not the US

Even domestic chinese airlines are only allowed 1 flight per week between china and any country

just as other countries closed their borders to China it seems fair for China to now close its borders or not accept flights to/from other countries with uncontrolled spread of covid.

maybe he just wants to choose his words carefully because the words will have an effect? unlike some other leader who says whatever thoughts pop in to his head

It's more like someone on base on your team stealing the catcher's signals to the pitcher and telling your batter what pitch is coming so they can hit a home run by cheating.

Here is a quote from one of the articles I linked: >Nortel was once one of the dominant telecom providers globally, but in early 2004, Huawei was caught stealing trade secrets from Nortel. This was proven by Nortel security expert Brian Shields. However, Nortel management had a hand in their own eventual downfall when it outsourced manufacturing to Huawei in the ’90s.

>In the hack, Huawei gained credentials of Nortel executives, including CEO Frank Dunn and Brian McFadden. It then simply stole documents that contained the future product and marketing plans of Nortel.

>The hack went even further than usernames and passwords. It has never been proven, but U.S. sources discovered that it was most likely Huawei that used sophisticated malware to record nearly every phone call that Frank Dunn made. After all of this, Huawei grew and Nortel faded, eventually going bankrupt.

All of the history of some mismanagement or funny accounting means nothing to me. Nortel had a large portfolio of IP that was stolen by China and ended up in the hands of Huawei and then the details of all of the deals they were trying to make to sell equipment were also stolen and used to out manoeuvre them, driving losses and unprofitability.

Large dams are a different ball game than the small run of river plants I have worked on and the ones discussed in the article.

Even at large dams it is possible to build fish ladders to allow migration.

When we were filling our head ponds (reservoir) we weren’t allowed to impound more than 10% of the total flow in the river.

I’ve worked on about 30 different run of river hydro electric projects over the last 15 years. Yes there is some environmental impact but the ones I have worked on have had a team of biologists and years of environmental studies and they would never result in a dead fish any more often that the river would have naturally by itself. If any habitat is destroyed they have to create new habitat such as spawning channels. They probably spend 10%-20% of the entire budget on environmental. These run of river plants don’t flood more than 1000m^2 area, use a weir instead of a dam, leave water in all sections of the river channel, and don’t cause unnatural changes in the river level at a rate greater than 1” per hour which is a very conservative rate compared to what the rivers of this size and nature naturally do by themselves when it rains or melts.

I know you said Dams and not weirs and not run of river plants, and big dams have their issues, but not on the same scale as the oil industry.

You should try living a winter where you have to shovel the driveway and scrape ice off your car and then see if Florida has more appeal.

“Working under the Health Canada research license, we have developed over 800 new Cannabis sativa lines and extracts and hypothesized that high-CBD C. sativa extracts may be used to modulate ACE2 expression in COVID-19 target tissues. Screening C. sativa extracts using artificial human 3D models of oral, airway, and intestinal tissues, we identified 13 high CBD C. sativa extracts that modulate ACE2 gene expression and ACE2 protein levels.“

Sounds like it hasn’t been tested except in a computer model.

I see that paid labourers built the pyramids[0], but slaves still existed at the time [0],[1]

very good point. The Canadian government should grow a pair and determine if nortel's IP was stolen and then act accordingly.

admittedly I am as biased as they come being a formel Nortel employee.

Chinese government hacking and Huawei hacking are one and the same as the end result is Huawei benefitting from the stolen information.

Had Nortel not been hacked they wouldn't have had to deal with their competitors ripping off their products and out manoeuvring them in their business deals.

The article I linked to cites an ex senior security advisor at Nortel stating that the hacking dated back to 2000, before the tech bubble burst.

Instead of being swept under the rug the demise of Nortel due to hacking should be a case study in why computer security needs to be given a lot more attention even if it is at the expense of convenience.

tech bubble burst in 2001, Huawei hacking of nortel was 2004-2009.

Canada does have a stake in the matter as Huawei hacked Nortel to steal their IP and then undercut all their business deals causing nortel to go bankrupt to the detriment of 94,000 employees and every single Canadian that owned just about and stock market fund.

It is embarrassing that we haven’t banned Huawei products in Canada yet.

Race based slavery began under capitalism?

Didn’t slaves build the pyramids? Was there capitalism then?

Have you read Sapiens by Harari? It touches on the fact that the Neanderthals and other species of humans died out ... perhaps due to genocide perpetrated by Homo sapiens, prior to the advent of capitalism by any measure.

Dispersion is no longer an issue but lower dispersion increases crosstalk so new subsea cables are high dispersion? High compared to early days when dispersion was a problem or just high compared to low dispersion cables which suffer from crosstalk? So there is the perfect amount of dispersion now?

It never occurred to me that fiber optic communication in glass actually used intensity to transmit bits. This sounds like AM radio albeit digital I guess the laser could be on or off. How long has it worked like that?

I always assumed it was like CDMA radio where like you say phase shifts correspond to a point in a constellation which represents more than 1 bit.

Did you see that someone was ready to manufacture n95 masks for the us government but they declined? That type of short sitedness is hard to fix.

Mechanical engineers also play a large role in power generation

The company has to continue to exist and do well for the equity to be worth anything.

items like transformers and high voltage circuit breakers that don’t have any smarts to hack. The interface is 3 wires in, 3 wires out, and for a circuit breaker one wire for a signal to trip and one wire for a signal to close.

The instruments to monitor temperatures and gas pressures usually supply an analog signal to a controller.

The article seems to confuse the heavy items made of metal with the controllers.

Schweitzer Engineering Laboratories http://www.selinc.com designs and manufactures pretty much all of the controllers and other smart stuff you could ever want for the grid in Washington state, and their gear is second to none.

Whatever poor guy at SEL has ground through all the math to implement the algorithms to protect generators, motors, and transmission lines needs to get paid which is going to be difficult if the product is “open source”.

Whatever smart grid shit China has i’m Pretty sure we don’t want.

Not sure what you are making but that’s way more advanced than any factory I’ve been to!

It might be renewable but it still makes air pollution. On certain nights when everyone in the neighborhood decides to have a fire the air quality is terrible - almost as bad as during summer forest fire season.

In BC ive heard of natural gas compressor stations have a natural gas turbine generator to run its own electric motor compressor. If it is connected to the functioning grid they can choose whether they Buy or sell electricity

There are no go arounds in a glider!

We Sync to a network drive with one note. Can you mount a cloud drive ?

We have a keepaas file that has the passwords for a number of client resources. The clients don’t roll their passwords very often.

Thanks for the links. Indeed if the synchroscope needle is turning clockwise I know the grid frequency is greater than 60 and if counter clockwise then less than 60 and exactly 60 no movement of the needle at all.

To me there is something about watching the inertia of the entire system change and it controlling itself to stop frequency excursions and then AGC or other human interventions to restore the balance.

Thanks for the ideas and links.

I was thinking of mounting this old synchroscope like a clock, except of course it doesn't tell time just how much faster or slower the grid frequency is to 60 Hz.

What easier ways do you suggest for kind of a grid frequency display other than a multi-meter in Hz mode?

I want to build a 60.0000 Hz source at 110V, only needs to be 5VA, so I can use a synchroscope to watch the grid frequency wobble around. I wasn't sure where to start so this will be very helpful. I'll still need some kind of an amplifier or transformer to get the voltage up from an IC at 5V to 110V. Also not sure if the synchroscope will work on square waves or if I have to generate sine waves

You can get hot water for way cheaper using solar hot water than PV. I can’t speak to the maintenance.

It is not the same situation in 2041 as it was in 1969, so of course they will not sign the same deal. They liked it at the time because it was their best option. Now: 1. the plant is built and paid for! there are no constructions costs and no construction risk. 2. energy is more expensive now, particularly renewable dispatchable generation

They clearly have a different hand to play now than they did in 1969.

Quebec owns 33% of the plant so they will be happy if NFL sells the power to the states at higher than the marginal cost of generation in QC.
