    PES: a pak SpaceX prebrala 10 zamestnacu, ti nalakali dalsich 1000 a dneska to budou Muskboys pokladat za Muskuv uspech.
    Krasne je to videt na tom, jak uspech Blue Origin dodava nikoli Bezoso hobby (to si snad nemysli ani Koudy) ale byvali zamestnanci z ULA a SpaceX.

    TOXICMAN: je zajímavé sledovat, jak je StarLink disruptivní technologie. Před (doslova mnoha) lety jsem četl pár článků, jak (např.) Honeywell Aerospace pracuje na integraci antén pro LTE a Inmarsat do letadel a jaké jsou s tím problémy...
    ...crcali se s tím léta, vyhlídky na přenosovou kapacitu byly dost malé (zvláště ta část satelitní), pro pozemní provoz (nad kontinenty) se uvažovalo o speciálních LTE stanicích vyzařujících především k obloze a s trochu upravenými parametry (rychlost pohybu přijímače a jeho vzdálenost), kdy pro pokrytí území o velikosti ČR měly tedy stačit 3-4 vysílače (opět by bylo zajímavé kolik by se na tom sešlo kapacitně zátěže a jakou by to mělo reálnou rychlost).

    No a najednou StarLink, integrace do letadel zjevně mnohem menší problémy, kapacitně a ani latencí to nemá prakticky problémy a hlavně funguje to i nad divočinou a hlavně nad oceány.

    TOXICMAN:
    @elonmusk
    Biggest advantage of lower altitude is that beam diameter is smaller for a given antenna size, allowing Starlink to serve a higher density of customers

    NEWS: SpaceX has released its 2025 Starlink progress report.

    Highlights:
    • Added 4.6 million new Starlink customers
    • 20+ million cruise passengers served
    • 21+ million airline passengers served
    • More than 1,400 commercial aircraft were equipped with Starlink, which is nearly four times the number of planes on which Starlink was installed on in 2024.
    • Equipped more than 800 business jets across 36 airframes with 5 Original Equipment Manufacturers.
    • Starlink is now connecting more than 150,000 vessels/boats, including cargo, tanker, tug, passenger, fishing, patrol, commercial cruise ships, and offshore supply vessels.
    • Over 650 direct-to-cell satellites now in orbit
    • Starlink Direct to Cell'has connected more than 12 million people, and counting, at least once, providing life-saving connectivity when people need it most.
    • On average, more than 6 million people monthly actively rely on Starlink Direct to Cell to connect their phones in areas where terrestrial service is unavailable.
    • 120 Falcon 9 Starlink missions
    • Reahced 600+ TBPS cumulative capacity
    • 35 new Starlink markets added
    • In January, SpaceX began launching Starlink V2 Mini Optimized satellites. These are 575 kg (1,267 lbs) lighter than the previous generation, and include improvements in reliability.
    • A successful flight of two Mini Lasers in Summer 2025 demonstrated greater than 25 Gbps data transfer between the demonstration units and existing Starlink mesh.
    • In 2025, median peak-hour global speeds increased by over 50%, with median download speeds averaging over 200 Mbps and typical upload speeds of more than 30 Mbps, with a median global latency around 26 ms.
    • This year, Starlink achieved and exceeded an impressive delivery rate of 70 satellites per week.
    • SpaceX's Printed Circuit Board factory quadrupled its output over the past year.

    TOXICMAN: teď už jen dotáhnout sběr zbytků atmosféry jako pracovní látky pro iontový urychlovač, aby funkční satelit nebyl limitován zásobou pohonné látky pro korekční motorky a bude to mít prakticky dokonalé...

    Starlink is beginning a significant reconfiguration of its satellite constellation focused on increasing space safety. We are lowering all @Starlink
    satellites orbiting at ~550 km to ~480 km (~4400 satellites) over the course of 2026. The shell lowering is being tightly coordinated with other operators, regulators, and USSPACECOM.

    Lowering the satellites results in condensing Starlink orbits, and will increase space safety in several ways. As solar mininum approaches, atmospheric density decreases which means the ballistic decay time at any given altitude increases - lowering will mean a >80% reduction in ballistic decay time in solar minimum, or 4+ years reduced to a few months. Correspondingly, the number of debris objects and planned satellite constellations is significantly lower below 500 km, reducing the aggregate likelihood of collision.

    Starlink satellites have extremely high reliability, with only 2 dead satellites in its fleet of over 9000 operational satellites. Nevertheless, if a satellite does fail on orbit, we want it to deorbit as quickly as possible. These actions will further improve the safety of the constellation, particularly with difficult to control risks such as uncoordinated maneuvers and launches by other satellite operators.

    @Starlink
    Glimpsing into the future, @SpaceX successfully deployed simulator Starlink satellites on two Starship test flights this year, as we prepare to launch the next generation Starlink and Direct to Cell constellations to orbit

    TOXICMAN: to je huste. Pro spoustu lidi u nas bude neuveritelne uz jen to ze to ujel autem na elektriku, natoz bez rizeni. Da se nejak zjistit prumerna rychlost? Kdyz zkusim odhad ze jel 20 hodin denne (coz je moc, ale treti den jel asi tech 20 hodin?) tak mi to vychazi na 73 km/h, coz s nabijenim je malo nebo hodne? Ale spis jel tak 16 h denne? Takze 91 km/h, to je asi uz dost? Nevim.

    I am proud to announce that I have successfully completed the world’s first USA coast to coast fully autonomous drive!

    I left the Tesla Diner in Los Angeles 2 days & 20 hours ago, and now have ended in Myrtle Beach, SC (2,732.4 miles)

    This was accomplished with Tesla FSD V14.2 with absolutely 0 disengagements of any kind even for all parking including at Tesla Superchargers.

    KAERO: na tomhle webu jsem asi pravda byl, ale nechtělo si převádět čtvereční stopy na čtvereční metry (nebo václaváky :-). Ok, já sem ty odkazy budu dávat... když mi nikdo nebude vyčítat, že je stejně nečtu :-) Každopádně je to hodně jiná bestie, než Starlinky... a evidentně, z druhé strany je to solární panel, a i když nebude osvětlený 100% času z optimálního úhlu, tak je to hezkých odhadem 45 kWp... hezký příspěvek do debaty o "datacentrech", mimo jiné...

    tak aj u FSD sa daju nastavit urovne agresivity :)

    Sloth: The most conservative (default in some configurations). Features lower speeds, more cautious behavior, and conservative lane selection (even more so than Chill).
    Chill: Relaxed and cautious driving with larger following distances, fewer lane changes, and stricter adherence to speed limits.
    Standard (or similar mid-level, sometimes referred to in context as Average): Balanced behavior with medium following distance and moderate lane changes.
    Hurry: More dynamic, with higher speeds and more frequent lane changes.
    Mad Max: The most aggressive. Includes the highest speeds, smallest following distances, most frequent lane changes, and least conservative behavior.
