There’s a server, a client, and a hacker in a network. For encryption, the client and the server need to share their private keys. Wouldn’t the hacker be able to grab those during their transmission and decrypt further messages as they please?
If you know the private key it is trivial to calculate the public key, but the reverse isn’t true
The public key and the private key are just two big prime numbers. The “trivial to compute” part only works once more information has been shared over the network, like it happens during key exchange. If you were to swap the prime number before initiating any contact it would work the same way.
Edit: I probably confused different encryption concepts
Yes, that’s why https needs certificates (and sometimes shows a broken lock) and why you need to accept the fingerprint when first connecting to a server via ssh.
Yeah, it’s safer than coal, on the same level as solar and wind. But it’s fucking expensive to achieve that equality! You can build 5 times the solar or wind capacity for the same price!
I’d wager most people, when talking about a plane’s autopilot mean the follow waypoints or Autoland capability.
Also, it’s hard to argue “full self driving” means anything but the car is able to drive fully autonomously. If they were to market it as “advanced driver assist” I’d have no issue with it.
What Tesla is (falsely IMO) advertising as “full self driving” is available in all new Mercedes vehicles as well and works anywhere in the US.
Mercedes is in the news for expanding that functionality to a level where they are willing to take liability if the vehicle causes a crash during this new mode. Tesla does not do that.
It also fails to mention how the accident rate compares to human drivers.
That may be because Tesla refuses to publish proper data on this, lol.
Yeah, they claim it’s ten times better than a human driver, but none of their analysis methods or data points are available to independent researchers. It’s just marketing.

Definitely won’t get an argument from me there. FSD certainly isn’t in a state to really be called that yet. Although, to be fair, when signing up for it, and when activating it there are a lot of notices that it is in testing and will not operate as expected.
At what point do we start actually expecting and enforcing that people be responsible with potentially dangerous things in daily life, instead of just blaming a company for not putting enough warnings or barriers to entry?
Then the issue is simply what we perceive as the predominant marketing message. I know that in all legally binding material Tesla states what exactly the system is capable of and how alert the driver needs to be. But in my opinion that is vastly overshadowed by the advertising Tesla runs for their FSD capability. They show a 5 second message about how they are required by law to warn you about being alert at all times, before showing the car driving itself for 3 minutes, with the demo driver having the hands completely off the wheel.
That is the new system. Tesla has no equivalent to it. Or to phrase it differently:
Drivers can not activate teslas’s equivalent technology, no matter what conditions are met, including not in heavy traffic jams, not during the daytime, not on spec ific California and Nevada freeways, and not when the car is traveling less than 40 mph. Drivers can never focus on other activities. The technology does not exist in Tesla vehicles
If you are talking about automatic lane change, auto park, etc (what tesla calls autopilot or full self driving) these are all features you can find in most if not all high end cars nowadays.
The new system gets press coverage, because as I understand it, if there is an accident while the system is engaged Mercedes will assume financial and legal responsibility and e.g. cover all expenses that result from said accident. Tesla doesn’t do that.
I would love to see this data, can you link it? Either a paper by unaffiliated researchers or the raw data is fine.
I am aware their marketing pushes the “10x better” number. But I have yet to see the actual data to back this claim.
Ok, but if it’s not bound to something like an official domain name how can you be sure the person who signed their posts as president of the EU (or whatever the official title is) to actually be that person is real life?
Fur ein Balkonkraftwerk braucht man kein Smartmeter, sondern eine sogenannte moderne Messanlage. Beide können den Strom rein und raus separat messen, aber die Smartmeter haben noch ein Funkmodul um live Daten zu verschicken.
Wundert mich nicht, dass so wenig funk verbaut wird. Ist vermutlich eine ganze Ecke teurer and liefert vermutlich nur wenig Nutzen.
Hab ich auch erst letztens gelernt, aber der Link redet nur von Smartmetern. Das sind moderne Messanlagen mit Funk. Würde mich stark wundern wenn dass Österreich so flächendeckend verbauen will.
So weit ich weiß leider ja. Wieland Steckdose ist auch noch offiziell nötig, da die neue norm, die auch Schukostecker erlaubt, noch erarbeitet werden muss.
Falls jemand ne qualifizierte Quelle hat die das Gegenteil (bezüglich Vorlagen, die der Mieter machen darf) behauptet bitte her damit!
Es lohnt sich auch jetzt schon richtig krass. 2-4 Jahre Amortisation, weniger wenn deine Stadt/dein Bundesland eine Förderung hat. Bei Lebenszeiten von 10 Jahren für den Wechselrichter und 30 Jahren für die Solarpanels.
Das Problem mit rückwärts laufenden Zählern sind prinzipiell halt die Kosten für die Netzinfrastruktur. Man kann jetzt streiten wie hoch die Vergütung für eingespeisten Strom sein soll, aber dass es nicht die vollen 30-40ct sind, die man für Strombezug zahlt, macht Sinn.
Ich könnte mir einen Stromvertrag vorstellen, bei dem der Grundbetrag ungewöhnlich hoch ist, aber der Netzbetreiber einem dann erlaubt mit Ferraris Zähler ein Balkonkraftwerk zu betreiben. Oder beim digitalen Zähler das netto abrechnet, nicht das brutto.
700kWh/a sind auch gut möglich mit 800W Wechselrichter und overpaneling.
Bei 30ct Strompreis macht das dann 210€.
Das ursprüngliche Problem bleibt weiterhin, man umgeht dabei Steuern und Kosten für Infrastruktur die man trotzdem nutzt. Wenn man jetzt einen alternativ Vertrag machen würde, mit höherem Grundbetrag bei gleichen Strombezugskosten, um das zu erlauben, würde das aber wiederum weniger das Stromsparen anregen.
Aber nach der Rechnung (max 210€/a) finde ich jetzt, dass dieser Betrag geringfügig genug ist, dass man das als Ausnahme erlauben könnte. Bei größeren Anlagen nicht, aber ein Balkonkraftwerk finde ich ok, so viel kann man mit nur einem System gar nicht von der Infrastruktur sozial-schmarotzen, die man dann ohne Bezahlung nutzt.
Ok, so I finally got to check this and I simply can’t reproduce your results at all.
Gpt4 turbo preview. Temperature 0.2
It answers all questions correctly. When pressed for details it did not lie to me, but instead correctly explained why Dijkstra can’t be used to find the longest path, and instead pointed out that this is a NP hard problem. It also correctly stated that Dijkstra can’t be used for graphs with negative weights. It correctly suggested Bellman-Ford as an alternative to Dijkstra and knows their respective runtime complexities (for Dijkstra it differentiated between the og version and one with a Fibonacci heap). When I told it my data type for distances does not support infinity it correctly stated the bound to be “larger than any possible path length in your graph”.
My initial opinion was that you simply should not use a tool for something it can’t do. I assumed that GPT is simply not knowledgeable enough to answer such domain specific questions.
I have now changed my opinion. I don’t know what your version of GPT is, but GPT4 turbo preview with a temperature of 0.2 answers all the questions in your post correctly. Therefore I think GPT can be a good teacher for even Domain specific problems if they are sufficiently entry level (but still domain specific, which is impressive!)
I’m not here to sell you something. In fact, the reason it took so long for me to reply, was because I only have access to ChatGPT at work and had to wait until I had free time there. I’m not paying closed AI any money either, but despite that I can accept that their flagship product is actually really good.
I am criticising that your post is based on a mediocre model (which version and temperature did you use?), but written as if it were representative of the whole field. And if I’m being honest I’m kinda salty that I was downvoted based on examples from such a meh model.
Since a few days ago llama 3 was released. On ai.nvidia.com you can test out different models, including the new 8B and 70B versions. I only did a quick check but even llama 3 8B beats the examples you gave here.
