Because it's so nice, here's another video of the Rohde & Schwarz ESH 3 and GA 082 from the DDK 9 shortwave transmitter. Modulation F1B and 50 baud with Sound!

自作エアバリコン基板届きました! 最小18pFの最大180pFといった感じ。 小さく作り直してFM用かな。 中心にノブをつけたいね。

Od roku 1945 bylo v atmosféře provedeno více než 1000 termonukleárních testů. Samozřejmě žádný z nich nezpůsobil globální oteplování, ale vaše kamna na dřevo, to je úplně něco jiného!

Want to know what really happened? As a Windows Developer, I've put together an explanation of the CrowdStrike IT outage. It covers kernel mode, the driver, how it happened and how to fix it! If you find it interesting please share it!

目標にしていた「セルフ環境でのasciiartのコンパイルと実行」ができました。CPUはシミュレータやエミュレータではなく実物のプロセッサ(DEC DCJ11)です。最初思うように動いてくれず、古代のC言語では負数の代入をy=-12ではなくy=(-12)と書くということを知りました。 #DCJ11 #PDP11 #UNIXV1

Here’s one of my favorite photos I’ve ever captured: the moment the international space station transited the lunar terminator, captured in broad daylight using a 14” scope. These shots require precise planning and a bit of luck to pull off, and I still can’t believe it’s real!
