For anyone wondering (like me) what COP is in this context, it’s Coefficient of Performance: https://en.m.wikipedia.org/wiki/Coefficient_of_performance
Calwestjobs · a month ago
and COP 15 is measure at 1.3'C temperature difference towards outside of fridge, so if it is 80f in your home then good luck to your lettuce.

90% of IDS, spyware, ADVERTS does not support ipv6... That is why most of (public) internet is not on IPV6

And what is most embarrassing is that truly fully IPV6 capable internet requires less of and lower powered "routers". "routers" will cost single thousands instead of hundred of thousands adn be more capable, speeedier. DDoS mitigations are easier in ipv6 too. And if every customer can have 2^64 IP (or even 2^56) addresses then you do not need "ports" anymore, every service on your server can have their own IP, or even every service customer can have their own ip address how much will that simplify CODE (source of bugs, of latency, of unnecessary payments) and lower energy requirements of login infrastructure ? and debugging ? also just right from bat you can trivially see on upstream router who is initiating DOS... PKI+IPv6 is gift from GODs! If your certificate is not issued for specific ip then "openssl" can drop connection in that instance. Is not that little bit more secure ? faster? less clunky. and with more oversoght for network "manager" ?

Israeli "network traffic monitoring hw used by law enforcement" was deployed in one European country and after few years of deployment public officials embarrassingly confessed that, device was not capable of monitoring IPv6 at all XD just sayin. people expect things working but even west devices are embarrassingly nonsensically flawed. Huawei / zte etc stealing sourcecode and blatantly copying it is even worse situation because they do not even understand how it should work. XD

I know it isn't the intended use case but I wonder how this would perform as a censorship circumvention method. The translation alone may be enough of a change to avoid the pattern matching used by firewalls.

I love any packet which has length field right after destination field. makes processing little bit faster.

13% less battery time is pretty wild just from updating the screen once per second but interesting to understand why.

(linux + KDE) i save 24% by using black (#000000) everything, backgrounds, full theme, contrast control setting in firefox etc. on notebook with OLED screen. also if possible not using Chromes / safaris youtube video player but downloading of a video makes huge energy savings. (and using MPV in linux or properly configured PotPlayer in windows. VLC or default MS video apps are bad at energy saving.)

And we are talking about 15+ hours of actual office work in webbrowser + little bit of python math. so add 24% on top of that... that is literally weekend worth of work on one charge. current generation of laptop CPUS is insane.

I'm totally not into Bitcoins but nice and interesting writeup. I very much like the interactivity of the article.

Yeah, Jupyter notebooks / literate programming for everything !

Safest way to generate seed words is a set of dice and printed table. It's odd they only encode 256 bits of entropy, which clearly isn't enough to make multiple 256-bit private keys.

just XOR two photos from your iphone and pick middle part of that... you can even sha512 that.

Maybe Subkey generation ?

Maaan, i stopped paying attention to bitcoin after Bitcoin Cash fork fiasco. Everything flew back into my consciousness. eth DAOHACK fail. Website, listing all possible BTC private keys. (de)Dusting. Printing signed transactions offline into QR codes on thermal paper... Good old days.

I am not sure BTC is still worth the hassle, most of hashrate is inside of USA (70+% =>51%...). most of BTC holdings is in USA... btc saga will end soon and badly in my opinion. BTC Cash made me pessimistic.

In Europe they have SEPA Instant Credit Transfer which allows people inter bank transfers in under 15 seconds. All KYC, all legal, all gov approved, gov regulated, all without fees to btc exchange / VISA. BTC does not even makes sense anymore. Technological innovations flew right past the BTC.

i am not even sure BTC infrastructure is quantum safe, blockchain "is", but i doubt rest of infrastructure is...

I bet you can run the entire thing in CircuitJS and it would still be faster than the original.
Calwestjobs · 2 months ago
yeah, 0.003$ MCU can run it.

Cassandra, the woman in the video, is a super interesting person. She essentially created the ‘nerd stuff’ auction market at sothebys, including enigma machines, tons of space stuff, she managed the Feynman estate auction..

I’d guess she is planning on making a market for this early Apple gear based on the video. Will the auction result pay for the video? Probably not, but they get to set the market price and be the auction house of record for this going forward, and that could be quite valuable.

Calwestjobs · 2 months ago
I hate lies, i hate manipulations.

Sothebys will be paid in multiples of what that video cost to make. How did you come up with opposite ? Most auction houses take 10- 30 % of price. So youre saying that this computer will cost less than 30k at final price ?

Also, Apple Computer was founded in 1976. But there were already "home" / personal computers sold from other companies for half of decade already. Or you can say that Apple employees did not built Apple-1 computer with already available intel 8008 CPU. Apple employees at that time were not innovators, they were marketers and solder monkeys.

Yes wikipedia is edited by public, and it is confusing on purpose. Apple has billions of dollars, so marketing department got paid to increase confusion on wikipedia articles for all apple products.

By charting computer history on timeline, you can see Apple-1 computer was nothing exceptional. It was just another random kit.

Apples push to sell to gullible teachers was toxic marketing strategy, which worked. So peoples exposed to this brand of computers in schools had emotional attachment to this brand. Yes apple targeted children. Not in China, in USA.
