There are a lot of jobs that are 24/7/365 without proper coverage from coworkers so people are always available and can’t turn off.

Other jobs won’t call you off shift but if you just had to deal with something traumatic like a car wreck it’s hard to leave that at work as well.

What did you use to do that?

Canada is home to Canada’s 13 most polluted cities in terms of air quality!!

Btrfs seems to work perfectly well in synology NAS. It must be some other combination of options or functions in use from what is available in synology that garners the bad reputation

I recall once google came on the scene I ditched altavista and never looked back. I was a teen but my recollection was that Google included the relevant paragraph of text from the page shown in in the search results whereas altavista showed one line that was often indecipherable gobbledygook - perhaps the page title matched a keyword - and it made it so much easier to scroll through ten results and identify the one that was the highest quality

Plus the no fast no clutter homepage for google compared to how many links can we fit in one screen for the portals

One study did identify heavy pesticide use due to concerns about Zika virus and measured changes in people’s brains before and after their trips to Cuba:

I’m still using redmine, it doesn’t look fancy but it works !

Perhaps software engineers looking for accountability would like the same level of liability that is enjoyed by their peers in civil, mechanical, mining, and electrical engineering?

Thank you for the assistance, “a mature” business would have been more accurate than “any”

This is what any business does and what you would do with your own growing business that you one day will no longer own too. You need defined roles with responsibilities and required skills that you can hire people to fill as people come and go in their own lives. Sucks to be a cog but cogs we are

Yes, they use the frequency as a common signal to respond to changes in load, that is correct.

With gps synchronized clocks and high speed waveform measurement we can see the propagation delay in the frequency across the country when there is a big event. Pretty neat!

I think the parent is more correct than you are?

The frequency does not provide an indication of load. The frequency can be 60.00Hz with 20,000 MW load in Ontario or with 10,000MW.

Changes in frequency provide a measure of changes in the balance between generation and load.

The generator’s prime mover’s governor has a droop function set so that typically a 5% change in frequency will result in a 100% change in output. This is how most generators on the grid arrest changes in frequency, but they would not restore the frequency to 60Hz. The droop allows for a steady state frequency error.

A handful of special generators are used to restore the frequency to 60Hz or balance the generation and load in an area.

The precise frequency does not matter, if one generator thinks the frequency is 59.99 and another thinks it is 60.01 their outputs will only be a little higher and lower than their load setpoint. It does not matter if they share changes in load perfectly evenly, so long as generators on the system in bulk respond according to their capabilities.

>So, why should you try Emacs in 2024?

>You’re a curious person and a constant tinkerer who likes playing with (insanely cool) vintage software.

>You want to experience life outside the mainstream.

>You’ve always wanted to learn a bit of Lisp.

>You want to build an editor that’s uniquely tailored to your needs and preferences.

>You’ve got a lot of time to kill.

Is this sarcasm?

I think focusing on the killer apps might have hooked me more than that closer!

I agree with you. If the systems/procedures/checklists are bad it is not the fault of a front line worker.

I thought I was replying more to a parent comment addressing the inability to people go who repeatedly make mistakes, which is acceptable unless they are not following procedures.

And be confident it is what it is meant to be, and meet the standards it is meant to meet

You can really dumb it down to why didn’t you follow the checklist? If someone makes the same mistake after being corrected three times and the proper procedures exist for the worker to follow then the safety culture provides the structure and justification for their dismissal

Indeed, hidden switch on a circuit somewhere and away you don’t go!

Seems like this batch of half baked cars receiving OTA updates are more likely to be the ones that are in repairable in the not so distant future, whereas parts for a 1990s toyota gmc or ford anything can be found cheaply and installed by any ambitious teenager.

Look at the stock prices of the companies installing owning and operating solar and wind farms. They are dogshit.

I think the boom is to capture the transmission system capacity near the best wind/solar sites, try and stay in business for the duration of the 20 year energy purchase agreement signed with local utility, and then mergers and aquisitions so that the larger entity can exert leverage upon renewal.

Power outages have a massive cost on society so the value of the marginal unit of electricity is very high.

Is the product being sold the setup of the bespoke models from their bag of what they’ve done before?

Regressions seem like the obvious way to detect anomalies to me since it should be 100% repeatable and make sense according to amount of heat being generated and removed , how to apply ML/AI to it I am not so sure

Right, make some scatter plots of bearing temp vs oil inlet temp and machine load, establish a fitted line, then can detect anomaly when new measurements vary from expected by more than some threshold.

Doesn’t seem that fancy, but better than waiting for a small problem to turn in to a larger problem.

I think it will also be useful in highlighting differences between identical machines, why does the one right beside the other run 5 degrees hotter on thrust bearing? etc

I’m just about to start digging in to 8 years of data from a few power plants with 16 turbines in total to see if I can identify some problems we might have before the sensor measurements exceed the alarm threshold.

Taking bearing temperature as an example, I think I will identify periods of time where the machine has already been generating for an hour so temperature have stabilized and then I will have bearing oil inlet temperature and machine load as independent variables, and bearing oil outlet and bearing metal temperatures as dependent values. Seems like it should be straightforward to find any anomalies but I’ve just started googling how to do this yesterday. There are lots of vendors hawking predictive maintenance software but I can’t imagine that I couldn’t get similar results with a few weeks effort and armed with Python and all of the associated libraries

So an average of 1.4kw/hr?

1000000W/mo / 30 day/mo / 24 hr/day = 1388

> Relying on people to always update the source of truth never actually works in practice in an organization of any size

I agree, the only place it has ever worked for me was in a team of 6 with a fixed deadline and liquidated damages for being late, and the source of truth was a binder with all of the drawings. What is highlighted is true, what is not highlighted is yet to be checked. Be careful precisely what you highlight (cable tag, terminal number, relay contacts, etc) or you are throwing the team and company Under the bus.

Doesn’t scale but works great for getting shit done correctly with no fuss.

Sounds like the case where a picture is worth a thousand words

Defect is related to the positioning of holes on the window frame and known as “short edge margin”

I think ICBC is worse than the private options available in other provinces.

Auto shops are charging them through the nose to fix all these German cars that get in accidents, and then the premiums for those drivers never go up by any significant amount.

ICBC had a bunch of money they had collected from premiums, 800 million or so I recall, and the government took it from them to flitter away on whatever, so the surplus paid in insurance premiums becomes another form of tax, Instead of ICBC being able to reduce premiums or needing to compete to offer the best price

Thanks. A lot of the hobbyist level ones did not do low frequencies at all or precisely enough to compare to electrical grid frequency

That one for 350 euros looks good

Anyone know a signal generator that can do 60.000 Hz?

I used to use the HP 3310A but they are analog and really old now
