<p>I mean there are multiple, multiple boundaries in place for this reason. I’d start by saying most “in the middle of the night” updates target non-safety critical systems in the car like the IHU. The update I received last night has a build date of 2024 reflecting extensive validation before general availability in 2026. It was field tested in limited markets after factory validation and had staged rollouts through dealers before going to general OTA availability.<p>Independently, I had to take my car into the dealer to get a safety critical recall installed via Ethernet that affected a braking system in certain edge cases and this was not installable OTA “in the night”.<p>While, yes, I am annoyed that the dealer price for my “infotainment” unit is $2k and reflects the technical specs of a 2016 mid tier android tablet running <i>Intel</i> cores; I do feel that vehicle is far safer with its airbags, 360 camera, lane keeping, and AEB on net than my 1970’s classic.</p>

<p>Just went through this. Sample size one:<p>While the fire resulted in the total loss of the house it was actually the water from the fire department not the heat that did proportionally more damage.<p>As a mental model you shouldn’t think of it as “what if my house burns down?” so much as “what if nice strangers roll up to my windows and chainsaw through my roof and spray 50,000 gallons of water in here?”<p>Yes everything in the mechanical room melted but everything in the rest of the house got hot, smoky, soaked and then moldy.<p>For root of trust materiel like social security cards, cash, passports put in a ziplock bag in a fireproof, waterproof safe. But for other storage I use clear “Ezy Storage” brand stackable 50L tubs labeled with Homebox QR codes. In the US, Target and Home Depot frequently stock them. I am very anti black and yellow tubs.<p>The majority of work post-fire goes to itemizing your house inventory for insurance. Even cataloging all your bathroom’s soaps by brand name rather than generic can make $100 difference. Multiply that by 500x different things.<p>From a threat model perspective I look at rooms from a “what would be salvageable in here if I emptied a swimming pool’s worth of water from some fire sprinklers”. Furniture and TVs are easy to replace. Other stuff less so.</p>

<p>I’ve seen it a lot in ‘90’s hacker / net adjacent cultures. It always reads as gen-x/elderly tech millennial to me - specifically post 1993 net culture but prior to mass adoption of autocorrect.<p>It was the norm on irc/icq/aim chats but also, later, as the house style for blogs like hackaday.<p>Now I read it as one would an hear an accent (such as a New England Maritime accent) that low-key signifies this person has been around the block.<p>Even more recently is a minor signifier that this text was less likely generated by llm.</p>

<p>That unreplicability between chips is actually a very, very desirable property  when fingerprinting chips (sometimes known as ChipDNA) to implement unique keys for each chip. You use precisely this property (plus a lot of magic to control for temperature as you point out) to give each chip its own physically unclonable key. This has wonderfully interesting properties.</p>

<p>Thanks. Higham explicitly addresses the authors substitution crime in section 2.5. Wonderful resource.<p>My complaint stems more to the general observation that readability is prized in math and programming but not emphasized in traditional education curriculum to the degree it is in writing.<p>Bad style is seldomly commented on in our profession.</p>

<p>I wish there was a Strunk and White for mathematics.<p>While by no means logically incorrect, it feels inelegant to setup a problem using variables A and B in the first paragraph and solve for X and Y in the second (compounded with the implicit X==B, and Y==A).</p>

<p>While I understand the spirit of this comment, if you look at the fossil record you’ll see that’s objectively not true.<p>Roughly half of the shifts in the last 11 evolutionary periods, over the last 500 million years, were caused by changes that occurred in a-few-hours-to-a-few-thousand-years with 75%-90% species lost.<p>Evolution did not fail to work then.</p>

<p>A few ways. This particular project is doing it by hand and very tedious.<p>The traditional way of transplanting large trees while keeping the root system intact is with a hydrovac. A machine the size of a jet engine that liquifies the soil with water and then vacuums it up. [1]<p>More recent developments have tried using an AirSpade which doesn’t use water but compressed air to blow apart and then suck the soil without making a slurry which is better as the soil can be redeposited in the same hole rather than discarded[2]<p>[1] <a href="https://youtube.com/shorts/HinwD5-Q2xA" rel="nofollow">https://youtube.com/shorts/HinwD5-Q2xA</a><p>[2] <a href="https://youtu.be/B3XomJ6Z1I4" rel="nofollow">https://youtu.be/B3XomJ6Z1I4</a></p>

<p>Do recommend the LG C series (C5 or C4 are new or the C1 series if you want a deal on classifieds - same hardware as the higher end models but needs a firmware bit flip). The OS is very rootable and it makes a great TV that doubles as a monitor. Supports free sync / g-sync. OLED is nice at this scale.<p>Text is very readable, refresh rate is good. It uses the same panels as the fancier G series in the larger sizes. One can root the firmware to make it go brighter. (Though this is screen works well in medium or dimly lit rooms. It does not shine in very bright rooms).<p>Plenty of YouTube videos singing the C series praises as a TV / Monitor.[1] LG webOS is also trivial/friendly to root in developer mode and network control of the tv is a nice to have.<p>Would avoid Samsung. I love the matte on the Frame and the design of the Serif but the OS is frustrating / impractical to root.<p>[1] <a href="https://youtu.be/Qtve0u3GJ9Y" rel="nofollow">https://youtu.be/Qtve0u3GJ9Y</a></p>

<p>I’m sure I’m missing something here but isn’t this common knowledge in sailing and climbing?<p>Specifically tying a knot with opposite chirality to one existing on a line can cause both knots to capsize and roll out.<p>One would not take it as given that three knots plus three knots would yield six knots in this scenario.</p>
