North Korea might be preparing or already did some military drills, or otherwise rapidly installing things/paths on So Island (소도) off Wonsan (~500 x 250 m). we see all this appear Sept. 28 - Oct. 1. Maybe missile targets/impacts, not sure yet. (Planet Labs imagery)

Got a report coming tomorrow on Kim's latest weapons factory tour, showing he visited: -🚨🚨modular TELs at the Sungri Motor Complex🚨🚨 -600mm MLRS at the March 16 Factory in Phyongsong -drones likely at an old building at a newly built section of the Panghyon 'machine plant managed by Jon Tong Ryol'

Looks like North Korea's newest destroyer was at Mayang-do naval base on Monday (Planet Labs imagery), a day after its deployment ceremony in Wonsan. Could stay there until construction finishes on a new base. The other destroyer is still at the Nampho bulk cargo port www.nknews.org/2026/09/nort...

Who are the 3 guys KJU awarded with top honors for "developing new combat weapon systems"? KCNA mentioned "scientists, researchers and officials," but there were only 3 guys. Short answer, not much is known, but some notes: kcnawatch.org/newstream/17...

NK state media didn't report its missile test last week, let's see about today's. Was the No. 52 Kang Kon destroyer involved? it was gone from Rason today, but no Planet image of Wonsan. NK has suggested the ship would hold SRBMs but hadn't done a test launch, then later switched up VLS config

Never seen this naval base at Kumgang be repaved before. often happens at places before KJU visits. just a correlation. sometimes the corvettes are seen here, not the destroyer so far.

This test took place from Sinpho, can see the submarine factory shipyard in the background. So lately it moved from Chongjin Shipyard to Mayang-do at Sinpho for KJU's inspection last month, then up to Rason to dock for a while, now back down to Sinpho/Mayang www.nknews.org/2026/07/kim-...

Strangely, South Korea's JCS did not announce detection of a North Korean ballistic missile test Thursday, while NK claims they launched Hwasong-11D CRBMs. Seems launch was from Ragwon County in S. Hamgyong (39.896586°, 127.874964°). Missiles pointed east and south www.nknews.org/2026/06/nort...

This is seriously fucked. Like for starters they’re using commercial web analytics that are in no way in line with federal privacy disclosure requirements…
Every webpage you load is making phone calls.
Not to people, but to servers around the internet, dozens per second, all invisible to you.
When I opened TrumpRx, I right-clicked the page, opened the browser's built-in inspector, and started reading the list. Mixed in with the routine traffic was a name I recognized:
PostHog. PostHog is a Silicon Valley analytics company whose entire business model is recording what visitors do on a website and reporting it back to whoever owns the site.
Mouse movements, clicks, scrolls, keystrokes. I had not typed anything. I had not clicked anything. I had just opened the page, and it was already on the phone with PostHog telling them about me.The recordings are not anonymized. IP addresses are not stripped. And the way it is configured, the data looks to your browser like it is going back to TrumpRx, but it is actually being forwarded behind the scenes to PostHog.
That is a technique used to slip past ad blockers by disguising where the data is really going, and it is not something I expected to find on a federal health website. So I went and looked at the other sites the studio had built. Real Food, the federal food policy site. Trump Accounts, the children's savings program. The studio's own homepage, ndstudio. gov. All of them had the same vendor, the same setup, IP addresses not stripped, the same forwarding trick. And onnot stripped, the same forwarding trick. And on ndstudio. gov alone, running alongside PostHog, was something someone had built entirely by hand. Five hundred and forty lines of custom JavaScript with a name embedded directly in the code: AutoMonitor. What it appears to do is rewire the part of the browser that handles how a page talks to the outside world, so that every conversation the page has with any server gets copied and forwarded to a private backend with no public presence. The studio has the structural ability to keep a copy of every recording as it passes through their infrastructure. I cannot prove they are keeping one. The pipe is built that way on purpose, and that is the part that matters.

Trump's posts on Iran have gotten progressively worse over the last week (and that's really saying something), from "see you in hell" to "a whole civilization will die tonight." Where are Republicans in Congress? The simplest approx is that they are staying silent because they support this

Looks like the engine testing took place on multiple days, first Planet Labs imagery suggests March 23-26, then changes to the ground under the stand again by the 27th and again 28th, the likely day KJU was there according to activity at the observation stand
