mem0r1··on Oil sector is lobbying for inefficient hydrogen cars to delay electrification
The argumentation is flawed.

1. Just imagine the required charging infrastructure if all vehicles were suddenly battery powered. Charging electric vehicles requires quite some power. Can the power grid installations sustain that (power lines, Transformer stations...) ? What resources (financial and physical (e.g. Cooper)) are required in order to adapt the infrastructure ? Just an example: A supercharger station which can charge a few cars at "full speed" simultaneously can draw > 1 Megawatt. Furthermore, superchargers are quite complex (and expensive) technology;

2. Batteries are not a suitable large scale energy storage. However, non-dispatchable, fluctuating energy sources such as solar and wind power require huge amounts of storage in order to sustain the power demand.

mem0r1··on NSO group iPhone zero-click, zero-day exploit captured in the wild
I wonder why Apple does not include a hypervisor in iOS, and "risky" processes such as iMessage, Safari (maybe a Secure Safari version) could then be executed in a separate virtual machine. The hardware (CPU + RAM) in the iPhones these days should be able to sustain it. Or would there be serious drawbacks to this ?
mem0r1··on Full Text of the Federalist Papers
I'm not from the US and I am not a native English speaker.

The federalist papers are, in my opinion, a true work of art. I find the linguistic elegance and finesse of these texts highly admirable.

Unfortunately, to my dismay, the usage of such "complex" language is discouraged nowadays. Or to express it in the appropriate linguistic style: Our modern era seems to espouse a predilection for accessibility and brevity, often at the expense of the stylistic grandeur and intellectual richness that was once the hallmark of our written and spoken discourse.

mem0r1··on C++ Implementation of StableDiffusion
It's really nice to see that C++ implementations in the ML field are growing. Personally I do not like Python very much. C++ does not force you to do things in a specific (Pythonic) way.
mem0r1··on FTX’s balance sheet was bad
Just wondering how this guy finished his MIT Physics undergrad studies without reading a book ? LOL
mem0r1··on Optimization of brain and life performance: Striving for playing at the top
Its actually an article from 2011/2012. "Avoid meat" -> refers to "the china study" -> deeply flawed. I don't think there is scientifc consensus supporting this claim. There are actually studies which state quite the opposite.
mem0r1··on Writing New System Software
I tend to disagree. (Modern) C++ is an incredibly powerful programming language. Contrary to some other languages it gives the developer maximal freedom and does not impose a particular way of doing things on the developer.
mem0r1··on Apple’s new M1 Pro and M1 Max processors
I really wonder if the CPU cores are able to access the memory with the specified high bandwith or if its just for the GPU cores.
mem0r1··on Is nuclear power our best bet against climate change?
Yes, it is.
mem0r1··on France bets on more nuclear power in face of Europe energy crisis
Excellent news, hopefully other European countries will follow that example. Especially Germany should immediately rethink and stop phasing out their remaining operational nuclear power plants.
mem0r1··on Why has the price of electricity in Europe reached record highs?
(Some) Advantages of nuclear power in comparison to 'renewables': - EROI (energy return on energy invested) - ratio of land required / energy produced - much lower flow of materials (rare earth etc.) - constant and very high power output (no storage needed)
mem0r1··on Why has the price of electricity in Europe reached record highs?
Not building new nuclear power plants in the last 30 years was a major mistake, in terms of energy supply security as well as CO2 emissions.
mem0r1··on Favouring tools is bad engineering (2018)
I couldn't disagree more. Liking and mastering a particular technology stack, tool or programming languague enables productivity and efficiency.
mem0r1··on For the first time in Europe, registrations for EVs overtook diesel
"Nobody needs to..." - always such a pathetic argument
mem0r1··on A Database of Historical Cookbooks
Is the database (or the underlying data) available as a SQL database, CSV, or similar ?
mem0r1··on Swiss Political System: More Than You Ever Wanted to Know
The lack of a constitutional court at federal level is in fact a major weakness of the system, there have been several attempts (1999, 2011, ...) to give the supreme court that competency (similar as in the US). Without such a court, the parliament is free to pass unconstitutional laws at their own discretion (which happens from time to time). Referendums are not a very good instrument for ensuring the constitutionality of legislation. Almost no citizen reads a law proposal which for example consits of 50 pages, let alone has the time or ability to ensure constitutional compliance of such. Approval of a particular legislation at a referendum merely signals basic political acceptance and is very much prone to manipulation by media (dis-)information, political advertisments, etc. At least the supereme court de-facto acts as a limited "constituional court" to protect the rights enshrined in the European human rights convention. Very interesting read: Federalist paper No. 78
mem0r1··on Does scrum ruin great engineers or are you doing it wrong?
I almost can't believe that it's 2020 and people are still disscussing or even worse "utilizing" Scrum. Pretty much all good and excellent Software engineers I know who had to deal with it at various companies hated it.
mem0r1··on FBI unlocked iPhone 11 Pro via GrayKey, raising more doubts about Pensacola case
For example if you encrypt your disk or a file using a password, you also do not store a hash, the decryption/encryption key is derived from your password using a key derivation function such as https://en.wikipedia.org/wiki/Scrypt
mem0r1··on FBI unlocked iPhone 11 Pro via GrayKey, raising more doubts about Pensacola case
Of course it is highly unlikely that it interfaces with the password screen. My point is that if you could extract a hash from the secure enclave it would make much more sense to brute force it on a powerful external cluster. However this seems not to be possible as the decryption is only possible inside the secure enclave element unique to the device, thus decryption attempts have to be done on the the device itself, GrayKey seems to have managed to circumvent the wrong attempts counter and/or the triggering of subsequent protection mechanisms.

mem0r1··on FBI unlocked iPhone 11 Pro via GrayKey, raising more doubts about Pensacola case
To my knowledge there is no technical reason why a hashed value of the passcode should be stored on the iPhone in any way. If a hashed value could be extracted from the device, there would be no reason to perform the brute forcing procedure on the device itself, which seem to be the case with GrayKey.
mem0r1··on Programming Language Rankings: January 2019
Somehow I just fail to unterstand how a technology like 'Java' can still be popular in 2019. At least to me it seems that there are much better alternatives for almost any use case I can think of.
mem0r1··on I Don't Like Debuggers (2000)
I think the main problem with a lot of high level language software developers (Java, ...) is that they often fail to consider the consequences of the fact that their software runs on real world hardware -> Memory access, Cache, Network Latency, Bandwith (Memory and Network), etc. Instead its all about artificial constructs as Design Patterns, OOP, etc. which often results in bloated, slow and therefore unusable software.
mem0r1··on New half-light half-matter particles may hold the key to a computing revolution
Polaritons are quasi particles in the sense of solid-state physics,quantizations of lattice oscillations „induced“ by transversally polarizized photons. These are not particles in the sense of the standard model of particle physics.
mem0r1··on Diesel cars can be banned from German cities, court rules
So what‘s with the constitutional guarantee of ownership ? I highly doubt that court decision is constitutional, I think and hope it is going to be overthrown by the German Federal Consitutional Court. I‘m so tired of the freedom hostile Green-Leftist agenda in Germany !
mem0r1··on Computer Architecture – ETH Zürich – Fall 2017
The undergraduate courses in Theoretical physics at the ETH are done with books (e.g. Goldstein: Classical Mechanics, Jackson: Eletrodynamics...) which are PhD Level in the US.
