    I'm not sure what distinguishes an "ES" bulb, but I did find this: https://www.screwfix.com/p/sylvania-mirage-es-t45-led-light-bulb-125lm-2-5w/249gx And you can get 25W equivalent (250 lumen) at Homedepot these days: https://www.homedepot.com/p/Bulbrite-2-5-Watt-25-Watt-Equivelant-A19-LED-Light-Bulb-Medium-Base-E26-Clear-Filament-2700K-4-Pack-862687/317691751...
  • Commented on The gathering crisis
    We're now seeing the same thing again with preserved railways. There is still a huge amount of Welsh steam coal available and not even difficult to get, but nobody can get permission to work it any more. Before Ukraine kicked...
  • Commented on The gathering crisis
    From the Wikipedia article: James Watt had tried unsuccessfully for several years to obtain accurately bored cylinders for his steam engines, and was forced to use hammered iron, which was out of round and caused leakage past the piston. In...
  • Commented on The ends of education
    Still haven't read past 100, but I thought I would post this anyway: Got my CS degree in 81 from the college of engineering. We covered a fair amount of theoretical stuff (abstract algebra related stuff, computer architecture, etc), and...
  • Commented on Books I will not write: BIGGLES!!
    >"I don't mind the indentation, I do mind the equivalence between var['k'] and var.k" >That's not Python. Maybe you're thinking of Javascript? You are probably right, I was thinking of Javascript. However, you can write: var.__dict__['k'] instead of var.k Which...

    If it wasn't clear, the co-worker told me about the Seymour Cray comment. The rest is from me......
  • Commented on Books I will not write: BIGGLES!!
    Story from back in the day: A co-worker I knew told this to me: The CDC 6000 series used Peripheral Processors (i.e. PPs) to do the I/O processing, and CDC's original OS design had most of the OS actually run...
  • Commented on Crimes against Transhumanity
    The local convenience store chain (Wawa) only has touch screen ordering (or, thanks to the pandemic, you can order on-line). Every once in a while you see somebody that freaks out and an employee has to help them, but I...
  • Commented on Books I will not write: BIGGLES!!
    So, linking the programming language thread to the Transhuman entry (ok, this is really a stretch): One of those strange little trivia things I find interesting: Ada Lovelace (world's first programmer) was Lord Byron's daughter. Lord Byron & Mary Shelley...

    Re: Eric Flint passing. Liked the first 1632 book, but somehow lost interest in the rest of the series. I don't know who on here knows her, but Dorothy Heydt passed away a couple of weeks ago, Hal is on...
  • Commented on Books I will not write: BIGGLES!!
    Re: Cars My mother told me stories of her family's first car. Her brother had to drive it, her father was not comfortable doing it. When her brother got married, she learned to drive so her father could still go...

    At least the NRO gave NASA a couple of old spysats... https://en.wikipedia.org/wiki/2012_National_Reconnaissance_Office_space_telescope_donation_to_NASA...
  • Commented on Books I will not write: BIGGLES!!
    I think OGH was talking about encrypting a symmetric key with a public key, and using the symmetric key to encrypt the payload. You get the efficiency of the symmetric key and the security of the asymmetric encryption. Pretty standard...
  • Commented on Abolish the monarchy!
    ... although I guess they could send me there to die, but I just don't see the ROI. Well, I think it would make an interesting retirement option. Consider that you might live long enough to contribute to the colony,...
  • Commented on Abolish the monarchy!
    So, I have some family that lives in Vegas, and I have never stayed there. We stay at a little motel outside Boulder City that has a nice view of Lake Mead, only about 30-40 minutes from the strip (and...

    The ICF showed up as the warp core in Star Trek into Darkness....
  • Commented on Holding pattern 2022 ...
    If I was going to try and make the Tuf stories believable, I would use this approach: The creatures that he creates are not merging the actual DNA from different planets, rather creatures (& DNA) from different planets are analyzed...

    There is one "book" I've read (well, it is part of the series) which knocked down the "why do they need that much money?" crowd. It required a god-like computer and an alien invasion, but hey, weirder things have happened,...
  • Commented on Bad news day
    On inappropriate models: Does anyone get apprehensive when you think about all the bad physics in video games? Talk about learning/using the wrong models......

    Why yes, she did catch you out :) Look up Monty Hall problem on wikipedia, it has an explanation why you should change (it is counter intuitive). I recall someone asking Monty about all this, and his reply was something...

    Ok, this is only vaguely related, but I give you The IBM Cheese Slicer! (complete with analog computer!) http://www.379136154956493191.com/ibm-cheese-slicer.html Restoration: https://www.youtube.com/watch?v=z8VhNF\_0I5c...
  • Commented on Bad news day
    Personally I'm a fan of the movie "Money ball". I have the book queued up for reading at some point. Basically it's how actual metrics could make winning teams instead of most coaches and players "gut feelings" on how...
  • Commented on Bad news day
    I think the term "water hole" comes from "watering hole", which is a place that animals (and people) gather peacefully (mostly). IOW, a natural attractor, which is what a quiet place in the radio spectrum would be for species that...
  • Commented on Bad news day
    A nonce is just some bits that prefix the data to be encrypted. For instance, for most AES variants (CBC, CTR) you need a 128 bit nonce. The nonce is not secret, and is sometimes derived from the context (e.g....

    On a slightly related note: Does anybody have experience with LiFEPO4 batteries for backup or for a solar/battery system?...
  • Commented on Oh, 2022!
    First of all, not all of the 7 dwarfs disappeared. Unisys is still around and still selling "mainframes" directly descended from the Burroughs Large Systems, and the Univac 1100 series. (And note that both CDC and IBM sold 5.25" and...

    At this point, I own 4 BD corded electric mowers, in various states of repair: 1) Bought it at K-Mart, low end model (this was ~20 years ago) 2) Got it from my Uncle when he moved out of his...
  • Commented on Oh, 2022!
    Re: Don't Look Up I did see the movie, and it really isn't about a comet hitting the Earth, that is just a plot device. The real plot is about how people react to undeniable evidence that the world is...
