    I'm so cold. It went down to -8°F last night and I had to drive home from work. My car took two attempts to start.

    HELP

    I'm really hoping for some good snow this year. Last year we got about 2-3inches, with up to a foot in some locations. So far this year we have had a light dusting at best.

    -10 wind chill here, buddy.

    I’m glad I did most of the snow work yesterday before it froze.


    Anyways, it’s story time with Fitzy!

    So I had to pick up my mom at an international airport located in a reasonably sized NE city. Her flight landed perfectly on time, at 8:20pm.

    Things promptly went down from there.

    The airline she was flying only had A SINGLE GATE for all of their planes, and that gate was full. The captain said it would be 20 minutes before the gate would be vacated,

    We all know what that means.

    1 hour later, the story changed to 5 minutes.

    Hmmmm. Nope.

    40 minutes after that, the captain said that he had been optimistic.

    He sure was. She didn’t get off the plane until, like, 11pm.

    Then the baggage claim took a shite and wouldn’t work.

    Heh.

    At midnight, the bags started rolling through, and my mom left the airport at 00:30, 4 hours after she should have been.

    I love my mom, but jesus I never want to find her in an airport pickup line at 1am after she has been up for over 24 hours.

    I didn’t get to sleep until 2am and I am kinda hating my life.

    Oh no, that was way before wind chill kicked in down here. After wind chill it was closer to -20 during the silly 30mph gusts we were getting.

    I had a similar experience where when we were in Charlotte when I was returning from a vacation in Cancun, and a storm hit, making the baggage claim defunct for some minutes. Then we got delayed to IIRC 10:00 due to said storm lingering around.

    I got a small amount of snow, then it turned to freezing rain which caked everything in a thick layer of ice, and today it was below 10 degrees, once I broke the ice on the door the bronco started first try. yay 4 year old gas and 236,000 miles + issues with the IACV and a nearly dead battery.

    Until the lambda sensor was swapped, my car was hating the cold, and it's not even that cold here compared to the US currently. With no sensor, car seems to have defaulted to using its base programmed map without any correction from sensors, until the turbo kicked in. A lean map. Throw in some denser air from the cold, it leaned out further. Been a nasty experience, glad it's been fixed

    Had -22F yesterday, kinda nice no smokers ruining air and not much people around, I wonder what they are afraid of, it just weather, not that cold really when you wear properly and cover your skin.

    Was -5 (degrees Celsius, or about 23 Fahrenheit) when I walked my dog around 2 hours ago. Not a single spec of snow on the ground, just frozen puddles and paths riddled with black ice.

    I didn't know I could enable vibration for BeamNG on my Xbox 360 controller this whole time... I've really been missing out :p

    Although it shakes out my batteries lol

    I just read a production version is coming.
    This would be an electric car I could get behind, especially on BBS RSs or HRE vintages.....

    There is quite a bit of info on it in this video (as well as the other Honda concepts):


    Its been a few months since I saw it, but they do interview some people from Toyota. So there may be some details in there that interest you.

    These are the Annualized Failure Rate (AFR) for 15 drive models from the BackBlaze drive farm from April 20, 2013 to December 31, 2018. My suspicions were correct, WDC drives, according to this, are junk. Almost 4% of the WD60EFRX, a 6TB Western Digital "Red" NAS class hard drive (used in a NAS setting) failed. You may look at that and see that 3.03% of Toshiba MG07ACA14TA or 2.77% of Seagate ST4000DM000 drives failed, and you'd be right. However, especially in the case of the Seagate drive, there are many more drives, and many more drive days (and therefore drive hours) spent. Imagine if the WD drives were used to the same extent the Seagate drives are, the AFR would be huge. Assume failure rates scale logarithmically (two drives, twice as likely one to fail, and so on...), I predict an AFR upwards of 8-12%. That is absolutely massive.

    Not that anyone outside of Hitachi really made an impressive showing here, in all honesty. 2.77% of drives failing in a NAS/drive farm setting isn't exactly a small number.

    You can't claim that Western Digital drives are junk based on the failure rate of (one batch of?) one SKU of one model.

    Also, failure rate curves are quite complex. Usually, if a drive is going to fail early, it will do so in the first few months. So typically you would see failure rates at their highest early in the lifespan of drives.However this will be different with every brand/model of drive.

    This is also testing drives in a server environment, which is quite different from the average home desktop or laptop. Not to mention that one server could be getting higher usage than another, could have better or worse cooling, more or less vibrations, and so on. Perhaps a technician accidentally knocked one of the racks hard while doing maintenance. Maybe one shipment of drives hard a rough journey to their servers.

    Obviously all these factors will hopefully become small enough with large data sets that they don't matter. But in situations like this there are huge numbers of factors many of which are not being controlled.


    My untested hypothesis on drive reliability is: If you want a reliable drive, buy a low capacity model. The more data you try to cram onto a platter, the smaller the tolerances that the drive has to deal with. But as I say, that is just a hunch of mine.

    In my personal perspective, from all the WD drives I've had, they really are junk outside of the Black series. At one point I had a stack of about 15 drives, all dead, a large majority Western Digital. They came good when the recycling center gave me $25 for them.

    The real test I have is a 3TB WD Green in my main system, which has clicked once or twice, and my server is running a majority of WD enterprise 1TB drives. I want to say 5/8 are WD, with a couple Seagate drives and whatever else I can get my hands on. That'll be on 24/7 365 in a raid configuration that is TBD. Whatever drives survive the longest I'll buy NAS specific models from that manufacture, no bias. My theory is if you can't bother to make a reliable consumer drive, you won't bother making a reliable drive period.

    But that's just hard drives, I don't have problems with WD SSDs. They aren't the fastest, but they work. I've used SanDisk and Inland SSDs made by WD (with Phison controllers) and they've all performed at or above expectations.

    I have had the following: Fujitsu(x2), Toshiba(x1), Hitachi(x1), WD(x1), Seagate(x1), Maxtor(x1)
    I've never had a failure.

    I've also got no doubt that the ones that are still in service will fail some day, assuming they aren't taken out of service before that point.

    The ones in my PC are doing ok all things considered. One thing that I would say is that the Hitachi drive is considerably and noticeably louder than WD's drive. So for a "silent" PC, I would avoid it. Not sure if this is also true for other Hitachi models or not.
    Hitachi Deskstar 7k2000 1tb: 26215hrs
    WDC Blue 1tb: 13435hrs

    Obviously I can't draw any conclusions from my own experience other than knowing that on the whole, hard drives tend to be quite reliable.

    In a server setting, you're already desiginin around 20% fail or more, so what you're saying is the Reds are great

    Out of curiosity I have been looking at land that is for sale in some cheaper parts of the country.

    Not sure this was quite what I was looking for...

    Now, I'm no expert, and I am sure a detached house would fit on that plot. However, I am not sure I would call it "ample space" for one.

    Had to crack my car window today because it was too hot in my sweater.
