  • I can half believe that George intended for Jar Jar to be the villain in TPM, but changed his mind by AotC. With RotS as it is, there's no indication that Jar Jar is the villain. Which is kind of a shame really. Such a twist could have "redeemed" the character in a way, and made up for all those awful Jar Jar scenes in TPM.

  • China working on standard for brain-computer interfaces • The Register
  • Eh, I think the Neuralink electrode retraction issue was a bit overblown. It sounds as though they were able to restore functionality to the shifted electrodes via a software update:

    In the weeks following the surgery, a number of threads retracted from the brain, resulting in a net decrease in the number of effective electrodes. This led to a reduction in BPS (Fig 04). In response to this change, we modified the recording algorithm to be more sensitive to neural population signals, improved the techniques to translate these signals into cursor movements, and enhanced the user interface. These refinements produced a rapid and sustained improvement in BPS, that has now superseded Noland’s initial performance.

    I think I'd still be more inclined to trust a device approved by the U.S. FDA over China's NMPA.

    Where are drafts saved?

    If I start writing a comment, but decide "nah, not right now" and back out, my partially written comment is "saved as draft".

    If I go back to the comment, the partially written comment is "restored from draft".

    • Are drafts stored indefinitely?
    • Is there a way to see all my current drafts?
    • If I keep creating new drafts without ever finishing them, will my storage get full?
    • Is there any way to delete drafts?

    However, I originally made this community back in the day when lemmy.ml was basically the only instance, and have since then moved my account to another instance (2 years ago) specifically for those same reasons of lemmy.ml being… hmm… politically charged

    Yeah, there have been some... issues lately.

    At most I could sticky a link to another community, or delete this one (which would be overkill imo)

    Instead of deleting it, you could lock the community so only moderators could post, and have a stickied post directing people to the new community on a different instance. I think that @Blaze@reddthat.com has had some success with this approach in the past.

    Not sure what the best instance would be though... maybe programming.dev?

    Payload info (NextSpaceflight):

    CatSat

    CatSat is a 6U CubeSat being built and tested by University of Arizona students, faculty, and staff.

    The satellite will launch atop a Firefly Alpha rocket into a nearly sun-synchronous orbit around the Earth. Thanks to some trickery on behalf of orbital mechanics, this peculiar orbit ensures that the satellite will constantly remain in daylight, maximizing the capabilities of the mission.

    During the mission’s six-month expected lifetime, CatSat will detect high-frequency signals from HAM radio operators all around the globe with its WSPR antenna, demonstrate an inflatable antenna for high bandwidth transmission, and provide high-resolution imaging of the Earth. The data this satellite provides will give insights into the variation of the ionosphere and the technical capabilities of the new systems being tested.

    KUbe-Sat-1

    If successful, KUbeSat1 will be the first satellite put into orbit by a major University in the State of Kansas. It is a 3U satellite that carries three main payloads: a Primary Cosmic Ray Detector (PCRD) to measure primary cosmic rays hitting the Earth, a High-Altitude Calibration instrument for KUbeSat (HiCalK) used for measuring very high frequency (VHF) from cosmic ray interactions with the atmosphere, and a camera to capture images of both Earth and space

    MESAT1

    Maine's first small satellite, MESAT carries three payloads designed by students in Falmouth High school, Fryeburg Academy, and Saco Middle School. UMaine and USM engineering teams are collaborating on building the satellite and getting it ready for launch in collaboration with AMSAT and NERRS. The CubeSat's launch is funded by the NASA CSLI program and its design and development are sponsored by NASA, MSGC, and UMaine.

    R5-S4

    R5 S2 and R5 S4 are 6U CubeSat technology demonstration missions by NASA's Johnson Space Center, Houston, intended to assess the suitability of commercial off-the-shelf components for free-flying extravehicular inspection capabilities including cameras, computers, and algorithms.

    These two 6U CubeSats are the first in the R5 series to include cold gas nitrogen RCS propulsion systems. Both are scheduled to launch to space in late 2022 for testing of both hardware and software systems needed for robust and low-cost in-space inspection.

    R5-S2-2.0

    R5 S2 and R5 S4 are 6U CubeSat technology demonstration missions by NASA's Johnson Space Center, Houston, intended to assess the suitability of commercial off-the-shelf components for free-flying extravehicular inspection capabilities including cameras, computers, and algorithms.

    These two 6U CubeSats are the first in the R5 series to include cold gas nitrogen RCS propulsion systems. Both are scheduled to launch to space in late 2022 for testing of both hardware and software systems needed for robust and low-cost in-space inspection.

    SOC-i

    SOC-i (Satellite for Optimal Control and Imaging) is a technology demonstration that will demonstrate an experimental attitude control scheme on orbit and provide educational opportunities to students at the University of Washington, Seattle.

    SOC-i uses an in-house developed and built 2U CubeSat satellite bus.

    The experimental GNC system is capable of reorienting the spacecraft while guaranteeing hard pointing constraints and minimizing the power drawn by the set of four reaction wheels. To orient the SOC-i spacecraft, the GNC system uses the 4RW0 reaction wheels from NanoAvionics as the primary actuators for the attitude control system. Five magnetorquers complement these wheels and are built into the solar panels on each face except on the bottom, where the camera is located. For attitude estimation, the GNC system uses a single digital sun sensor custom-built into the solar panels, three 3-axis magnetometers, and three 3-axis gyroscopes.

    The imaging system serves as one of two payloads for the SOC-i mission. A single uCam-III from 4D Systems was selected as the onboard camera and is mounted on the bottom end of the 2U chassis.

    It was selected in 2020 by NASA's CubeSat Launch Initiative (CSLI) program by the CubeSat Launch Initiative (CSLI) to be launched as part of the ELaNa program.

    TechEdSat 11

    The TechEdSat 11 (TES 11) is a 6U (2×3U) CubeSat that will function as a high-temperature, accurate deorbit reentry nanosatellite.

    TechEdSat-10 contains 150 watt-hours of power storage, eight radios, nine processors, and a graphics processing unit. Additionally, the small satellite carries four cameras, including a stereoscopic virtual reality camera experiment.

    Like several TechEdSat missions before it, this mission is demonstrating the exo-brake technology in its largest iteration to date. The exo-brake is designed to deploy an umbrella-like "brake" to increase drag and take a small satellite out of orbit. In this mission, the exo-brake can be controlled or modulated by commands from the ground in order to target a re-entry point. In the future, this could enable sample return missions from orbit and future planetary missions.

    Additionally, it hosted the DCS Use Concept Validation project to determine if satellites, primarily small satellites in low earth orbit, can successfully interface with the data collection system (DCS) receivers and thus provide low-rate data (100, 300, or greater bps) service to satellite users; primarily to assist in launch, early orbit, and anomaly (LEO&A) operations or low data required observations.

    It was selected by NASA's CubeSat Launch Initiative (CSLI) to be launched as part of the ELaNa program.

    Serenity

    Serenity, developed by Teachers in Space (TIS), is 3U CubeSat that will provide low-cost opportunities to test educational experiments in space.

    Teachers in Space has previously guided high schools and other academic institutions in developing and flying experiments suborbitally with high-altitude balloons, stratospheric gliders, and rockets. This will be the first orbital satellite mission for TIS.

    Serenity will be carrying a suite of data sensors and a camera that will be sending data back to Earth through the use of HAM radio signals. There will be several ground stations connecting with the satellite during its orbital period. These ground stations will be collecting data and pictures sent back down to Earth.

    The satellite was one of the passengers on the maiden launch of the Firefly-Alpha rocket but was lost in the launch failure. A reflight was on the second Firefly-Alpha rocket and reached orbit, although lower than planned.

    Stats

    • This will be the 1st launch of Firefly Alpha this year.
    • This will be the 5th launch of Firefly Alpha overall.

    Script to semi-automatically bookmark YouTube preroll ads

    The goal

    Bookmark a YouTube preroll ad with as few mouseclicks and keystrokes as possible.

    But why?

    I like to have the option of rewatching or referencing an interesting or funny ad at a later date. Most ads are unlisted videos, which makes them nigh impossible to look up.

    My previous workflow (12 steps):

    1. Right-click on the video player, select "Copy debug info"
    2. Alt+Tab to a text editor
    3. Ctrl+V the debug info into text editor
    4. Ctrl+F for "addocid"
    5. Ctrl+C the advertisement video id
    6. Alt+Tab back to browser
    7. Ctrl+N to open new browser window
    8. Type "youtu.be/"
    9. Ctrl+V the video id
    10. Wait a fraction of a second for the URL to redirect from youtu.be/[video_id] to https://www.youtube.com/watch?v=[video_id]&feature=youtu.be to https://www.youtube.com/watch?v=[video_id]
    11. Ctrl+D to bookmark the video
    12. Ctrl+W to close the browser window

    My new workflow (4 steps):

    1. Right-click on the video player, select "Copy debug info"
    2. Press F9 to run the script
    3. Check that the bookmark is saved to the correct folder
    4. Ctrl+W to close the browser tab

    The AHK script:

    ``` #Requires AutoHotkey v2.0

    F9:: ; Press F9, then a thing happens { ActiveHwnd := WinExist("A") ; Save active window ID to variable Haystack := A_Clipboard ; Save clipboard to variable NeedleRegEx := 's)."addocid": "(.?)",.*' ; Regex witchcraft

    ; Regex breakdown: ; Example line: "addocid": "kU5Y-LRSteA", ; We need to use "s)" otherwise it will treat each line in the clipboard as a separate string. ; We need to flank the line we're searching for with ".", otherwise it will search each line ; We need to use the non-greedy "?" option when capturing the video ID "(.?)" otherwise it will capture the rest of the file

    VidID := RegExReplace(Haystack, NeedleRegEx, "$1") ; Do the actual regex replacement URL := "https://www.youtube.com/watch?v=" . VidID ; Concatenate the video ID with the rest of a YouTube URL

    Run URL ; Open the video in the new tab Sleep 1000 ; Wait for the tab to open WinActivate ActiveHwnd ; Reactivate the window Sleep 1000 ; Wait again? Send "^d" ; Open bookmark dialogue and create bookmark } ```

    Potential improvements

    1. Automate clicking on "Copy debug info": I figured out how to use AHK to open the right-click menu in the YouTube player, but I can't figure out a reliable way to locate and click on "Copy debug info". It seems like it is in a different place depending on whether it is the 1st or 2nd preroll ad.
    2. Save bookmark in specific folder, rather than just the default bookmark dialogue box. No idea how to do this elegantly.

    This is my first AHK project, so I've probably done several things incorrectly or inefficiently. Any feedback would be welcome :)

    I'm so happy to have found an AHK community on Lemmy, however small!

    ALOS-4

    >The Advanced Land Observing Satellite-4 (ALOS-4) is a satellite to observe the Earth's surface using its onboard phased array type L-band synthetic aperture radar (PALSAR-3). The L-band radar technology has continuously been developed in Japan. With further improved observation performance compared to the predecessor PALSAR-2 aboard the DAICHI-2 (ALOS-2), JAXA and its prime contractor, Mitsubishi Electric Corporation, are developing the satellite aiming at achieving both high resolution and a broader observation swath. > >Unlike observations by an optical sensor, radar images can be acquired day and night as it does not require sunlight. Moreover, since radio waves can penetrate clouds, the images can be obtained regardless of weather conditions. The ALOS-4 will leverage these merits for observing and monitoring disaster-hit areas, forests, and sea ice. In addition, it will also challenge new areas such as monitoring infrastructure displacement. > >The ALOS-4 will be equipped with the Automatic Identification System for ships (AIS) receiver, as was DAICHI-2, so that the satellite will also monitor oceans by receiving AIS signals from vessels as well as by acquiring the PALSAR-3 images. The SPace based AIS Experiment (SPAISE3) is a high-performance satellite AIS. Effective countermeasures against radio wave interference regions are taken for the SPAISE3 with multiple antennas and ground-based data processing; therefore, the detection success rate of a ship in the heavy marine traffic areas will be improved compared to DAICHI-2. SPAISE3 development is JAXA's ongoing project in cooperation with NEC Corporation.
