    Important Misskey / Sharkey security update

  • You're not the only one

  • Instagram, along with nearly two thousand other sites, is supported by yt-dlp (the modern successor to youtube-dl, for those living under a rock). I've only tested it on Instagram once (just now), but I have used it to download clips from Twitter in the past, which deliberately obfuscates the interface to make this difficult.

    If you've never used a command-line program before, yt-dlp is pretty simple. Just type yt-dlp url-of-your-video, for instance. yt-dlp https://www.youtube.com/watch?v=3BFTio5296w and it will save the video in your current directory.

    On Windows, you will need to make sure yt-dlp.exe is in a directory specified by your %PATH% environment variable. Otherwise, you must replace yt-dlp with the full path of yt-dlp.exe, e.g. C:\Users\Porkroll\Downloads\yt-dlp.exe https://www.youtube.com/watch?v=3BFTio5296w.

    I highly recommend running any interesting videos through yt-dlp for archival purposes. Who knows when the Silicon Valley platforms will remove them?

    Unfortunately, I don't know a good way to do this on Android / iOS.

  • Are you winning, son?

  • They may be, but I've seen larger convoys of APCs and Humvees rolling down the interstate in "peace time." If a ground invasion is happening, it will take a long time to move the needed hardware and personnel into place. On the order of months. And then the question is, where do you stage all these forces before making the charge? If bases throughout the Gulf are already being hammered by drones and missiles, a camp on the edge of Iran's borders would surely be turned into the moon.

  • Convertables.

  • We don’t even know who’s running yet. Implying people aren’t allowed to criticize shitty hypocritical politicians because they might, at some future date, announce they’re running for president is completely ridiculous.

    This person ALMOST gets it, but I have to hammer down on the "we don't even know who's running yet" part. Why don't we know? Why is there no obvious champion of the popular will? We are going to wait around until a small slate of candidates who are acceptable to the donors and media barons are selected for us, and they are all going to be repugnant imperialists.

    The US political system is governed by a series of filters. To be deemed eligible, you first must go through the Cursus honorum of state government, the House of Representatives, and then the Senate, or be the executive of a large state or serve as Secretary of State or something of that stature. Along all of these steps, you must maintain the favor of our oligarchical media apparatus. You must never draw the ire of the party machinery, making sure to never cut the line in front of any of the corrupt sleazebags who have "tenure" over you because they have been wetting their beaks for decades. By the time it is finally "your turn," you have sold out any principle you ever had, or you have been locked out of the system by any one of these filters.

  • I am just spitballing here, but I wonder if this is trade-off made for their MARV designs. I don't know what the exact burn time / coast time / stage time profile looks like for these missiles, but for the final stage to be able to operate on descent and maneuver near sea level as it approaches its target, they might be sacrificing high altitude efficiency to maximize power on the final approach.

  • The shape of a rocket exhaust plume is a function of exhaust pressure vs. atmospheric pressure. The exhaust pressure itself is influenced by the shape of the rocket nozzle. The shape of the rocket nozzle can be optimized for certain ranges of atmospheric pressure, but its shape is static and has inherent trade-offs. To increase performance in vacuum conditions, the nozzle must be much larger than a nozzle designed to operate near sea level. This increases the mass of the rocket and makes it more fragile. A trade-off which might not be worth the gained rocket motor efficiency depending on the application.

    We saw exaust plumes like this during the "Twelve Day War" last year as well. It just seems to be a characteristic of some of Iran's high altitude missile designs. As the missile climbs to near-vacuum altitudes, the pressure differential increases and the exaust plume expands. You can clearly see it going though this transition in the second photo as it gains altitude. The first photo is a bit more confusing but I think it is just a matter of perspective and the way the camera is being held. The phenomenon in the video appears to be mostly caused by camera focus rather than an atmospheric phenomenon.

    For reference, here's a diagram from a model rocket magazine.

  • It's extra funny because there's an official flag folding procedure (which ultimately produces a triangle) and these clearly were just folded like a stack of bed sheets.

  • "Sen. Blumenthal warns U.S. may be getting ready to send troops into Iran after classified briefing" - Dropsite (https://xcancel.com/DropSiteNews/status/2028973382247620966):

    Sen. Richard Blumenthal said he is “more fearful than ever” that the U.S. could end up sending “boots on the ground” in Iran after a closed-door intelligence briefing on the escalating war.

    The classified session at the U.S. Capitol included testimony from Marco Rubio, Pete Hegseth, and John Ratcliffe about the administration’s strategy following the U.S.–Israeli regime change war campaign known as Operation Epic Fury.

    Blumenthal said lawmakers still lack clarity about the administration’s objective, questioning whether the goal is regime change, destroying Iran’s nuclear program, or countering “terrorism.”

    He also criticized the heavy secrecy surrounding the briefing, arguing that more of the information should be made public.

    No concrete developments, still a will-they-wont-they situation, but it is wild that they are even considering this.

  • I would ABSOLUTELY not recommend Signal for org work. Personal communication, sure, but org infrastructure should be self-hosted, and MUST NOT require PII (phone numbers) for access.

    It is better than SMS, but not sufficient. It has all of the same vulnerabilities as WhatsApp from an architectural point of view. Their reputation, and the availability of free software clients is the only major difference.
