Why, what would happen to my lettuce if I set the thermostat near the cooling element to e.g. 3°C and have the cabbage be somewhere between that and 4.3°C?
Unless I'm very mistaken, this 1.5 degree delta is between the hot side (the condenser at almost your room temp) and the cold side (evaporator inside the fridge).
That is, if you want to chill your cabbage to 4.3 degrees C, your room temp should be not more than 5.6 degree C. Or... if it's 25 degrees outside, in an ideal case your cabbage is 23.7 degrees cool.
Btw, max theoretical COP increases rapidly as T'hot - T'cold shrinks to zero. Your practical AC or fridge delta T is much more than that, depending on the weather.
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" ?
I'm a networking guy by profession + a big IPv6 fan as well (yay HN these days! news.ycombinator.com->2606:7100:1:67::26)... but don't hold your breath that IPv6 will lower the price of routers at all, let alone by a factor of 10x. From a hardware perspective there are a few minor gains with changes to the protocol but there are also some losses due to the address and network prefix sizes taking up more expensive TCAM/SRAM.
You still want ports, they actually make networking hardware cheaper overall by moving some of the scaling requirements out of the IP layer and into the transport layer. Imagine needing router which can hold 1,000,000 IPv6<->MAC address bindings just because you have 1,000 clients in your network using new addresses instead of ports! ND code is more complex than the code to bind to ports, but I still like the introduction of ND more than not regardless :).
IPv6 infra will probably never adopt the cert stuff you mention. The protocol is just designed to be able to, it doesn't mandate it. In practice it's almost never done and having everyone do it would likely be harder than getting people off IPv4 has been. On the internet routing side, PKI with BGP doesn't really care about the address format and works fine with IPv4.
For the network manager the 2 biggest changes are 1) All of their client subnets are /64s, no more subnet mask tables. 2) No more NAT, which feeds into the debugging side of things, though some of this is advantage is intentionally lost in a tradeoff for increased privacy via temporary addresses. In the last one it's tempting to tie that back to enormous hardware gains but, in reality, the box at that position of the network needs to statefully track sessions regardless of if it needs to translate them, and that's the majority of the cost.
Around 50% of internet packets are IPv6. It's not the future. It's now the present, and IPv4 is the past.
It's a shame they still have ports in IPv6, but I can see why: imagine having to ARP (IPv6 calls it ND) every connection separately. At least you can just allocate another privacy address if you need more than 65535 concurrent connections to the same destination.
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
(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.
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...
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.
exactly! using your phone which knows when you are going to toilet, and shares that with advertisers, for "super secret communications" ? makes no sense.
