2·6 hours agofrom what i understand, it’s also impossible to copy this thing and every single instance will turn out slightly different. also it will continue to learn on whatever data it is fed so you might end up with something useful, that will degrade, is on a timer and has no backups

7·4 days ago“there is a global far right conspiracy that attempts to reinvent alchemy, colonize space and build a machine god, which they intend to use to enslave everyone else. it’s informed by misreading of old scifi and racism, but it only took off after certain hp fanfic was written. currently it’s commanded by a californian polycule with a drug problem, but also counts in their ranks white house officials, and possibly some from russian government”
unfortunately this does not make a great conversation starter. whaat? a cult took over an entire government of south korea? this could never happen here

2·4 days agocmos logic still beats it, because main source of heat are switching losses (all these gate + parasitic capacitances being charged and discharged, and some related phenomena). relays store more energy, and that makes situation worse, even if you make them as MEMS

9·5 days agowtf is deal of that segyges person. now they’re convinced that openai will solve room temperature superconductors in silico real soon, because altman vagueposted about it
and this all based on lk-99 fraud case, nevermind that there’s no high temperature superconductivity theory, or how prohibitively computationally expensive computational chemistry is, and i guess it’s not accurate enough anyway, this all with people that do computational chemistry coming in their thread trying to explain this, then posts this

3·5 days agoone of them also works for anthropic
also, the unfounded confidence of openai guy makes me think that they might have done that before, and some random grad might have folded much easier under this kind of pressure
and looks like there’s another case of openai thievery https://xcancel.com/ValerioCapraro/status/2097791836269977996 https://bsky.app/profile/timhenke.bsky.social/post/3mv4ouxlnsk2z

21·6 days agothe purpose of system is what it does







openhamprep explanation is wrong
When you consider a segment of wire, it has some inductance and capacitance in that small segment, and the wider it is, the lower inductance and higher capacitance are. In other words, both X_L and X_C go down as diameter increases. Electric field lines within antenna are mostly perpendicular to wire everywhere except on ends, where they spread in all directions, which means that there’s some residual capacitance there that needs to be charged each cycle. This is called end effect and the wider wire is, the more of it you get. In fact, the same aspect ratio (length/diameter) gets you the same end effect ratio each time, and it’s usually in range of 0.98-0.95. If there’s insulation, then insulation has lower velocity of propagation as it has higher permittivity than air, and it is in place with highest electric field intensity, and this can also shorten necessary wire length a couple %. The more insulation there is, the more shortened antenna becomes
But wait, there’s more. We can think of antenna as a lossy resonator, where R is Rrad which for halfwave dipole would be 72 ohms, + loss resistance which is smaller, and neither are changing fast with frequency. What is changing faster is X_L and X_C, and the wider wire is, the smaller both of them are, and this means that you can go further off frequency and still have acceptable SWR, i.e. antenna made with wider wire has more bandwidth. For HF this means using masts or wire cages instead of single wire, but for VHF this gets more practical
Rrad depends on physical antenna length, and if antenna is shortened, then how it was done, but for the range we’re here it won’t change much
you can consider antenna wire as a transmission line, but it will need to include ground as the other side of transmission line, and then impedance is dependent on wire diameter to height over ground ratio. it’s not very useful
