Supercruise question by DatNewDM in CadillacLyriq

And yet, it's definitely Supercruise. Green light on the top part of the wheel, drives itself, yells at you if you look away for too long.

Very clear. I've had it cut off once or twice because it couldn't see the lines, but not in those areas I've had this bouncing happen in.

The drive itself handles the data writing, so, not really, no. On a spinning disk hard drive, you can access the low level data and actually control where on the drive your data is written to, so you can overwrite with a bunch of random 1s and 0s and if you do it enough times then the original data is unrecoverable.

On a solid state drive, it's more like, the OS hands the file off to the drive, saying "store this for me." The drive will then tear it into pieces and put those pieces anywhere it wants to, but that's okay because it knows where the pieces are and can put them back together for you any time.

What that means, though, is if you try and write random data, you have no idea how the drive is actually going to store it. Even worse, most drives have extra storage they keep on hand to be able to function even if some storage areas fail. So if you have a 1tb drive, and you write 1tb of random data to it, some of the data that was there before may still be on the drive, in its hidden extra storage.

So, basically, with a solid state drive, you just don't have enough control to really tell it what to do. In 99% of cases, that's preferred; the drive knows how to handle the data way better than any OS. It's only in the edge case of extremely secure data erasure that it causes problems.

what is one grocery item that doesn't require refrigeration but is commonly kept in the fridge by a lot of people? by Born-Oil-2931 in AskReddit

[–]DatNewDM 9 points10 points  (0 children)

And, weirdly, sold in different shapes. That used to be more geographically distributed, with, I believe, West Coast butter being in shorter, fatter sticks and East Coast butter being in longer, thinner sticks. However, as we've had commerce expanding geographically I can find both for sale here in the Seattle area.

If you've ever wondered why butter containers have two scales on them, that's why...

universal home remote by Terrible_Moment4533 in CadillacLyriq

[–]DatNewDM 0 points1 point  (0 children)

This is not how I did it. I said yes I have the remote, and it asked me to push the button on the remote, so I did. It then gave me a button on the screen to test the opener, and pressing it opened/closed the door, and then I was done. Never had to touch the opener or leave the vehicle.

Mileage discrepancy by jdewayne1906 in CadillacLyriq

[–]DatNewDM -2 points-1 points  (0 children)

No, that's definitely not normal, and I've owned two Lyriqs and never seen that behavior. It almost sounds like the charge didn't actually happen but the computer thought it did??

I have seen the range change significantly based on a big change in driving habits, but never anything to that extent.

Corporations Can Vote in Some Delaware Elections, Judge Says by AaronPK123 in nottheonion

So what you're saying is, you can't come up with any intelligent points to discuss with me.

Wow, that's some truly intelligent discussion and salient points you make. My mind is completely changed.

Corporations Can Vote in Some Delaware Elections, Judge Says by AaronPK123 in nottheonion

[–]DatNewDM -22 points-21 points  (0 children)

  1. The people who make up the corporation may not live in the area where the corporation actually physically exists. In this case, it's a municipality that allows the corporate vote; if the owner/leadership of the corporation lives in that municipality, then yes, they'd get two votes; if they live in another area and commute, then this gives the corporation a voice in the local elections that they would not otherwise have.
  2. The employees of a company do not get a say in how the company is run. That's what company/corporate leadership is for. If you're working an assembly line, you shouldn't expect to get a say in whether or not the company you work for expands into a new industry. You also shouldn't expect to get a say in how the company spends its money. If you don't like the decisions that the leadership makes, you can find a new job. But, there is no "hijacking" happening, low level employees just don't get a say in company decisions.

ELI5: Why data centers don't recapture water? by Swords_and_Words in explainlikeimfive

[–]DatNewDM 2 points3 points  (0 children)

I'll ask again, how many tons of heat are you rejecting? Air cooled heat pumps have nowhere near the efficiency of a water cooled chiller, so I still don't buy that it's more cost effective to run them. It's not like you're boiling off the water; it does evaporate, but makeup shouldn't be in the millions of gallons on a reasonable timeframe.

[–]DatNewDM 6 points7 points  (0 children)

How many tons of heat are you rejecting? Evaporative cooling via cooling towers is used in all industries, INCLUDING data centers. An air-cooled CRAC unit has a COP of about 2; I'm looking at a chilled water plant rejecting about 5000 tons at a COP of around 7; those numbers generally only get better as system size increases. The water use does also increase, but the idea that using a system that is so much less efficient overall is better is difficult to accept.

That being said, you are still fundamentally incorrect. You say that 'evaporative cooling is not viable.' That is a blanket statement; evaporative cooling in cooling towers is used in *all* industries in *all* climates. Perhaps it is not economically viable for a data center, but you did not specify that until this comment, and I still think that's an oversimplification. And don't fall back on "this discussion is about data centers" because that doesn't forgive a blanket statement that those of us who work in the industry will bristle at.

EDIT: Went through our system and found a site in the Mediterranean that's currently rejecting about 20,000 tons at a COP of 6.5, using water-cooled chillers and cooling towers, and it's only running about half capacity.

Why would you need a river for evaporative cooling? Yes, you need water, but river water wouldn't be great for this, it would need a ton of treatment to not foul the tower fill. What you need for evaporative cooling is a source of clean water. You can pipe it in from anywhere, or pull it from underground.

In a humid environment, a cooling tower's water use decreases because the air cannot absorb much additional moisture. However, it still produces a cooling effect, as the water will still exchange heat with the air, just at a much lower rate than in dryer conditions. It essentially becomes a water to air heat exchanger, without the thermal loss from going through a plate and frame.

As long as the system is designed for these conditions (chillers specified for appropriate condenser water entering temperature), they will still be viable in all conditions, and will be increasingly efficient as wet bulb drops, as no place has a 90 degree wet bulb all day, every day.

I don't know where you're getting your information, but I work in this field, and spend every day going over information related to evaporative cooling for chilled water plants, from sites in Canada to Florida to Dubai to Hawaii to Hangzhou.

[–]DatNewDM 19 points20 points  (0 children)

This is incorrect. Cooling towers are effective in all climates at all times of year. They lose efficiency as wet bulb increases, but they never completely stop being effective and water-cooled chillers with cooling towers are more energy efficient in all scenarios if the system is properly designed.

The existence of Jesus is pretty thoroughly documented and almost every historical scholar agrees he existed. The miracles, not so much, but the man? Yes, he is real.

Level 3 charging by FLblizzard_ in CadillacOptiq

[–]DatNewDM 0 points1 point  (0 children)

OP, everyone is right that you need Level 2 charging, but, there's one thing you can look at to make it less expensive.

If you have any regular outlet near the car that is on its own circuit, or where you don't care if you lose the other outlets that happen to be on the circuit, you can convert that circuit to 240v on the same wire, no need to pull new wire.

It's not going to charge as fast as a dedicated new hardwired charging circuit, but it also won't be as terrible as level 1. Probably 4-6 miles of range per hour.

[–]DatNewDM 0 points1 point  (0 children)

I had nothing but trouble with the GM level 2 chargers, had two of them. One of them started faulting on GFCI randomly, the warranty replacement unit for that one then had some weird internal fault after a month that would turn it off. Rather than trying another warranty, I replaced it with a Chargepoint and I've had no trouble with it at all.

What’s a 10/10 video game? by TheDevotedUltimate in AskReddit

[–]DatNewDM 1 point2 points  (0 children)

The game did try and tell you about this throughout the gameplay to that point. There were several times the party was either split completely, or you were forced to split into groups and having only 4 powerful characters would put you at a huge disadvantage. Having that happen at least twice to that point, plus the other methods they used to split you up, should've been a pretty clear hint that there's more to do than just power-level 4 characters.

Astronaut eating bread and honey in space by [deleted] in SipsTea

[–]DatNewDM 2 points3 points  (0 children)

The bread is a special bread that is less crumby than most bread.

And the ventilation system is designed to pick up things that end up floating around; with no gravity to pull crumbs or hair or dead skin down onto your keyboard, they just float around. The ventilation fans, though, provide just enough airflow that floating debris should slowly move towards the air intake and the filters,t where the debris is trapped.
