"However it is a pity that they cannot be disrupted. I have not had experience with platforms like Carvana.."

Where I see the street is littered with unused bikes for sharing (sometimes a trip hazard if you are not looking where you go while on the iPhone SE talkin) and unused cars parked for sharing. They multiply. The disruptors must be using a utility function with payoff after the sovereign wealth fund managers backing the thing cashout at the top, retire and die. And then there is no return on investment after WeWork's hard partying and snort.


The latest Aviation Week podcast on the dumped $4B plus Boeing M&A deal for the commercial arm of a Brazilian smaller player has one industry insider analyst put positive spin on the 737MAX8. Business as usual.

Not hard to imagine scenario after political wrangling where initiative is launched and the first thing the new entity does is buy Oracle for HR very special edition which eats up all the budget for the first years of its life. And nothing is left to the original reason for being for that entity.


"Use the $5 billion to build housing for homeless people."

Homeless people are outside the circle of social distance and, therefore, social sympathy. ⁣Just sayin' the way to lower the cost is to produce more and sell more reprints of the manual at scale.


The creator of ARM speaks well of RISC-V and considers ARM yesterday's old news and has moved on. Comparing MIPS to ARM in essentials of architecture is MIPS more beautiful? ARM I understand is a mess that has evolved for its niche.


I find the latest architecture versions are all remarkably similar as they have all adapted to the same environment:

The old 32-bit Arm (now called Aarch32) was quite different and only somewhat RISC-like. Arm's Aarch64 however is mostly derived from MIPS64 with a lot of modernization plus some parts (exception levels) from 32-bit Arm.

MIPSr6 was an attempt of modernizing MIPSr5 by removing all the ugly bits (delay slots!) but the incompatible instruction encoding prevented it from being widely adopted. You cannot buy a single MIPSr6 machine that a mainline Linux runs on.

RISC-V's design looked at all RISC architectures (Berkely RISC, MIPS, SPARC, Power, Arm, ...) for inspiration and took the best parts of each. Leaving out all the historic baggage means it's simpler (the manual is a fraction of the size), but most of the important decisions are the same as in MIPSr6 and Armv8/Aarch64.

One notable difference is the handling of compressed (16-bit) instructions: ARMv8/Aarch64 doesn't have them at all (like RISC-I/RISC-II, ARMv3 and MIPS-V), MIPSr6/microMIPS needs to switch between formats (like ARMv4T through ARMv6) and in RISC-V they are optional but can be freely mixed (somewhat like ARMv7 and nanoMIPS).


It's disappointing that RISC-V designers swallowed myths that resulted in unpleasant ISA details.

For example, the notion that condition codes interfere with OoO execution has been repudiated; Power and x86 both now rename condition registers. Lack of popcount and rotate in the base instruction set are glaring omissions. (That x86 got popcount late, and that the bitmanip extension will have them if it ever gets ratified, are no excuse.) It was silly to make the compare instruction generate a 1 instead of the overwhelmingly more useful ~0.

We only get a new ISA once in a generation. It is tragic when it is wrong.

It is possible, in principle, that popcount and rotate could be added to the base 16-bit instructions, but I'm not holding my breath.


Section 5 would be better with a laundry listing of at least three unrelated sources observing a security audit at sourceware and runtime level.


"For one, no labor could be hired to perform many farm duties, and certainly not for the amount that farms pay foreign temp workers."

The opportunity is definitely there to roboticize the backbreaking work those faceless poorly dressed "peasants" are subject to under the watchful gaze of new bossman from investor capitalized Communist Party China. Isreali robotics firms have demo proofs of concepts years ago. Even Elon Musk has posted YouTube clips of potato size sorting machine.


If this was feasible it would have happened already. I don’t think we’re there yet. And how many years are we not to have veggies, fruits any other items that come directly from the labor of immigrants? And Americans won’t do this type of work, even if paid better I think


That sounds a lot like picking cotton. If the immigrants don't become Americans (who supposedly "won't do this type of work") then what are they? It sounds an awful lot like keeping slaves. They even arrive crammed in the holds of ships, unable to speak the local language.

Americans will do the work. They won't if an excess of unskilled labor drives down the wages, but that doesn't have to happen. We don't need to keep an underclass.


"back then you didn't just have to know what Pi is, you had to have the smallest program to calculate it"

A floating point division on two three digit numbers used to be used as a good enough approximation to 𝛑.


3.14159 is often a good enough approximation for pi.
