kennend3··on Companies save billions of dollars by giving employees fake “manager” titles
https://nationalpost.com/news/politics/federal-union-wants-4...

You tell us, is a 47% increase in pay "normal"?

why did the body intended to help with the negotiations write this:

The union’s proposals “do not appear realistic for what should be a fairly advanced stage of negotiations. The numerous proposals are not focused and they would result in an increase to compensation far beyond what is reasonable,” reads the unanimous report signed by three commissioners.

You can simply step back and watch what is taking place in Canada right now.

https://nationalpost.com/news/politics/federal-union-wants-4...

Because it is not going anywhere, they had an independent body get involved, their commentary says it all:

"The union’s proposals “do not appear realistic for what should be a fairly advanced stage of negotiations. The numerous proposals are not focused and they would result in an increase to compensation far beyond what is reasonable,” reads the unanimous report signed by three commissioners."

These same union employees are also fighting "unilateral contract changes" that mandates they return to the office, but did not fight the unilateral contract changes that allowed them to WFH in the first place?

The contract they signed was for "IN_PERSON" work, so they are simply being asked to do what they signed up for prior to COVID.

kennend3··on How to find a tiny radioactive source while doing 70 kph
When you think of things like Gamma or x-rays you cant relate them back to "light" because while there are similarities there are also a number of differences.

Gamma penetrates rocks, these sensors are used to help determine the density of rock by measuring how much was stopped by the material.

This is also why Gamma sources are so dangerous, because things like a coat, a car door are effectively "transparent" to them.

If there was just "one small stone" in front of the source it would almost be like it wasn't present at all.

kennend3··on The US Hasn’t Noticed That China-Made Cars Are Taking over the World
so.. by this logic the US automotive companies should be cleaning house?

I mean if you throw billions of dollars to them.. you could consider that a "state subsidy" right?

" General Motors received $49.5 billion, repaid $38.3 billion, which left taxpayers an $11.2-billion loss.

The “old” and “new” Chrysler companies were loaned just under $12 billion from the federal and Ontario governments with just over $9 billion recouped, resulting in a $2.92-billion loss. "

kennend3··on Reverse-engineering an airspeed/Mach indicator from 1977
Nice article and cool you are here for questions.

> The unit is powered by 26 volts, 400 Hz, a standard voltage for aviation.

Any idea as to the history as to why this is the case?

I assume higher voltage is useful for lower amps? But why 400 hz?

Seems odd to use such a high voltage if components such as this must have internal transformers?

kennend3··on We need a lot more electricians
For which country is this?

Only a handful of countries actually us 110/220

If it is North America, I think you mean 120 and 240

https://www.powerstream.com/cv.htm

kennend3··on We need a lot more electricians
I live in a large home (~5,600 square feet) in the "Greater Toronto area" built in 2000. I have a 100A service.

This has never been a problem for us.

Stove, furnace, and dryer are gas. So the only "power hungry" device we have is our Air Conditioner.

kennend3··on We need a lot more electricians
> Do Americans quote large appliance current at 220V or 110V equivalent?

Fist, North America is a 120/240V system, not 110/220. For the life of me i will never understand the confusion over why some people, including North Americans keep referencing 110 volts?

The code is clear, 120 Volts +- 5 to 10 percent?

Perhaps because the "allowed range" is 110 to 125? If i measure my house right now, it is 121 volts and this is pretty typical.

Your dryer example seems like it is running on gas?

In North America, electric dryers use anywhere from 1800 to 5000 watts.

AC depends on the home size, the location, etc. Mine has a 60A 240V breaker but again the "code" states you can only have an 80% "continuous load" on a circuit so technically this circuit can not pull 14,400 continuous watts.

One thing Europeans dont grasp is the difference in house sizes vs north ameria and so naturally our appliances are larger and more power hungry.

What may take a European washer 2 loads, most north american washer/dryers will do in one. So the "power usage by load" is the same?

Using a device like a range's maximum power draw is dishonest. If a north american range is twice the size of what is available in EU, but not all the elements are in use at once... does that mean something?

kennend3··on NYC officials say they can't find EV garbage trucks powerful enough to plow snow
This is a shockingly high amount of FUD but little facts.

Lets start at the top shall we?

Diesel doesn't "burn" like gasoline does.

"If you toss a lit match into a puddle of diesel fuel, it'll go out."

You need to atomize it first, or heat it up a lot so it starts to "flash" or it wont "burn".

So, a firetruck with a large diesel tank is fairly safe because it takes a LOT to get it to start burning. At first all the heat is simply absorbed by the diesel slowing warming it up until it reaches its flash point.

Next, your temperatures are beyond MESSED UP.

Ignition temperature for a lithium battery is just 121 C

https://www.nature.com/articles/srep07788#:~:text=The%20crit....

The Auto-ignition temperature of pure lithium is just 179°C

https://inchem.org/documents/icsc/icsc/eics0710.htm

https://webwiser.nlm.nih.gov/substance?substanceId=284&ident...

I have no idea where you get 2,000F (1,093C) from but this is so wrong it is embarrassing. This temperature is almost to the point Iron catches fire:

https://en.wikipedia.org/wiki/Autoignition_temperature

Batteries are also prone to shorts and spontaneous fires which may explain stories like this : https://www.republicworld.com/world-news/us-news/tesla-model...

There is also the "fun" reaction between Lithium and water, which firefighters often use on fires...

First, i dont consider Citadel, JS, etc "fintech" because they are not in the same line of work.

" Fintech, a portmanteau of "financial technology", refers to firms using new technology to compete with traditional financial methods in the delivery of financial services. "

This is NOT what people like CIT, JS, etc. do.

So maybe FinTech is being hit very hard, but from what i hear Cit, JS are doing just fine (no real layoffs).

kennend3··on How to Build an Exchange (2017)
One difference is Google, etc are all doing massive layoffs and i doubt JS, Citadel, etc will do this.

kennend3··on NYC officials say they can't find EV garbage trucks powerful enough to plow snow
> A driver brings a truck to a charge location, grabs a truck that's been charging. Easy peasy.

Tell us you have no idea how much a garbage truck costs without telling us.

Must be nice to have a few million dollars in "spare" trucks lying around. Garbage trucks can run up to $400,000 EACH.

This is how you propose to waste taxpayer money, by replacing perfectly working trucks with EV's where you need to buy "spare" ones as well?

> I wouldn't want an inextinguishable box of lithium near something hot like a fire. Would you?

This.

My brother is a captain for a fire department. I visited the hall many times with him and found the station design odd. He told me it is built that way because there have been cases of fire trucks being too close to major fires, and the truck catching fire back at the station.

The station has "blast doors" that automatically close if the bay is on fire to protect the rest of the station. (sounds funny right.. fire halls catching fire??)

Not sure they would want a "flammable metals" fire in their bay.

> Would be excellent EVs. They have super low millage and you'd not have to worry about things like stagnant fuel.

There is no "/s" so it is hard to tell if you are being sarcastic or not. Assuming you are not... EV's make TERRIBLE fire trucks.

How long does it take to fuel a fire truck? How long to recharge one?

You are blissfully unaware of how fire trucks work. Many are also diesel pumps, they arrive at fires and the truck itself is a massive water pump. Tell us, how many hours can a EV drive the water pump for? The diesel version can probably run for several days if needed.

My brother is a firefighter, they are AFRAID of electric vehicle fires because well.. Something about electricity + water?

If i call 911, i expect a fire truck to arrive, not some BS about how they had a power failure and their rechargeable truck isn't working.

PS - Stagnant fuel isn't a real thing. Fire trucks are generally very well maintained, they are expensive, they are essential life saving machines. They don't just sit somewhere forgotten and have their fuel go "bad".

They are driven almost daily because firefighters are expected to know their area and so they drive around to see where hydrants are, look at new subdivisions and sometimes simply to make sure it runs property.

They also have detailed logbooks and are inspected a LOT.

>Generators are a thing that pretty much every one of these services will have. Because you can't have a fire station, EMT dispatch, etc go dark because of a grid down situation.

> And, consider this when thinking of a "grid down" situation. How do you pump fuel if the grid is down?

First.. Fire stations use batteries then generators.

Second, you point out they have generators.. wouldn't that be used to transfer fuel answering your own question?

> The solution is really quiet simple, recharge the trucks and buy a few more to account for the fact that you have to recharge an hour for every 4 in operation. Stop trying to run your trucks for 12 hours straight.

I had to re-read this twice to make sure i wasnt misreading something.

The "simple" solution is to redesign the entire system, buy more vehicles, hire more drivers, etc because you are "pro electric" and electric vehicles cant perform the job?

Here's an idea.. Diesel vehicles are built to run 24 hours a day, and this is why they have large fuel tanks and heavy duty engines. Perhaps EV should be built to run 12 hours a day as well?

if the EV cant compete, then don't use it for this use case.

why should they "stop trying to run your trucks 12 hours a day" when they have done this for DECADES?

you make it sound like this 12 hour day is the problem, it is not, it is the EV's failure to keep up that is the issue.

kennend3··on Tesla FSD Beta 10.69.25 Struggles in Snowy Detroit MI: A Scary Video
Let us know if you also disagree with the nhtsa studies, and how your anecdotal evidence overrules them.

https://www.nhtsa.gov/laws-regulations/standing-general-orde...

They list 18 fatalities involving FSD, but i'm sure their inaccurate per your understanding?

I'd say a FSD, like we see in the youtube video, or that kills people as the NHTSA shows isnt a benefit to road users.

IN the youtube video, can the car go over 15 seconds without attempting to run into the curb?

kennend3··on Tesla FSD Beta 10.69.25 Struggles in Snowy Detroit MI: A Scary Video
> I'm not sure what sort of tires were fitted but it seemed to struggle more when FSD was engaged vs. the human driver.

As a Canadian who has driven in snow for 33 years "blaming the tires" is odd. Most of my life i drove on all seasons and only got "snow tires" 4 years ago because I get a discount on my insurance for having them.

The reason it is having issues is because it is attempting to accelerate too quickly for the road conditions. Perhaps snow tires might help a bit, but if it is unable to handle "all seasons" and a bit of snow.. that itself is a problem and snows may not fix it because they are not some sort of magic that suddenly gives you amazing traction on something slippery like snow.

If there is over a few CM of snow on the ground, i can spin my 2 yer old snow tires as fast as i want... Speedo showing 90km/h while i am hardly moving... All i need to do is disconnect the TC and press hard on the gas, the snows quickly lose traction and spin.

The human driver is obviously lighter on the acceleration due to road conditions and so less TC is needed.

kennend3··on U.S. judge says Celsius Network owns most customer crypto deposits
THIS!

The investors are being "made whole" at the direct expense of the customers.

The outcome here is shocking, stating Celsius owns customer assets? when did this transfer of ownership take place? if so, why is it referencing the customers at all?

Seems like stealing from the customers to minimize the losses of the investors?

kennend3··on Tesla FSD Beta 10.69.25 Struggles in Snowy Detroit MI: A Scary Video
Hmm.. story was run by CNN, ABC, etc.

If you dont agree with CNN, what about the others?

Even Reuters ran it : https://www.reuters.com/business/autos-transportation/tesla-...

If you read the article, it is still under investigation as well.

"The Tesla driver told police the FSD malfunctioned but police were unable to determine if the software was in operation or if his statement was accurate, according to the report which was made public after a Reuters request."

It is possible it is FSD, also possible the driver is lying.

> Maybe the first Google hit isn't enough to get a complete understanding of the situation in this case.

Maybe no google hit will work because sometimes people consider things more of a "religion" and no evidence can convince someone to sway from their religious beleifs. What does it say when you wrote "It's literally impossible for the CNN article to be" when multiple respected agencies carried the story?

Do you have Developer access to Tesla and know for a fact this is not true? If so, have you contacted any authority to report this?

Edit: do you dispute the fatalities as well?

I'd love to see FSD up here in Canada in the winter.

We play "guess where the lanes are" at over 100km/h because our major highway system (401) ranges from 2 to 8 lanes wide and remains fully open.

Sometimes Humans get it wrong and crash even having years experience driving in snow, how will a tesla handle road conditions when everything is white and any "lane indicators" are buried in snow?

https://ottawa.ctvnews.ca/opp-responds-to-numerous-crashes-o...

Will FSD ever advance beyond some "ideal weather and road conditions" toy? I guess time will tell but it has a LONG way to go to support all road conditions.

kennend3··on Canada bans most foreigners from buying homes
As a Canadian I can tell you my views of what is wrong here.

NIMBY - Any time anything is proposed the locals consider how it could remotely impact them and protest.

They protest ANYTHING. As a quick example - we built wind farms, people protested, we built Solar farms, protesting..

Try building anything in Canada and you will meet NIMBY protesters. I ride my bike a lot and there are areas where they can infill and proposed a modest three story unit. The entire area is full of signs about how this small unit "doesnt fit with the area"? This very same area is desperate for housing?

Politicians dont care about the citizens, they care about getting reelected so they qualify for their gold plated pensions.

Trying to address the NIMBY issues and actually build housing could cost them an election so inaction is their best strategy.

kennend3··on Airbnb removed my negative review
The pendulum of regulation will swing too far in the other direction, it ALWAYS does.

Mostly because the government sits around and does nothing until things get really bad, then they institute very strict rules to prevent a repeat.

Had they gotten involved earlier they would have had more flexibility with the regulations.

kennend3··on Airbnb removed my negative review
I take it you have never experienced an AirBnB neighbour?

The people behind me have done it a few times. How can i tell they had "guests" over?

I find beer bottles, coke cans and garbage on MY property. There is the obvious noise from the late night "pool parties" as well.

Normally people dont care what their neighbours do, but when it starts to impact others, people start to care.

kennend3··on Airbnb removed my negative review
keep in mind why some of those taxi regulations were created in the first place.

In the not so distance past there was a FLOOD of drivers, few rules and regulations and eventually a "race to the bottom" (too many drivers chasing too few fares).

Then the pendulum of regulation swings TOO FAR in the other direction, creating the "medallion" system where these are worth a small fortune.

A happy medium is where the market self-clears with reasonble regulations to protect both drivers and consumers.

AirBnB is in the same boat. It was a good idea when it was individuals renting out unused rooms for some extra cash. now AirBnB is an unlicensed hotel, where people buy up houses specifically for AirBnB.

There are countless stores of people renting property, and then turning around and putting that on AirBnB.

And strongly agree, some rules are dumb, but the correct approach should be to push for change, not run illegal businesses like AirBnB, Uber, etc.

If i called someone to come get me from "A" and drop me off at "B" how is this "ride sharing" and not a taxi service?

kennend3··on Airbnb removed my negative review
> AirBnB's entire business is predicated on skirting regulation.

From time to time you spot underappreciated comments here. This is one of them

AirBnB, Lyft, Uber, etc - their entire business model is predicated on skirting regulations.

Then people are surprised they don't keep honest negative reviews? Why would a company which is knowingly violating rules care about your negative review?

They make money from hosts putting their places up for rent, not from those renting and if a negative review causes a listing to be removed... Clearly it is far more economical to remove the review instead.
