November 7, 1941. The German army is so close to Moscow that officers can see the city's spires through their field glasses, and the Soviet capital seems about to fall. And on this morning, in the falling snow, Stalin holds a military parade in Red Square to mark the anniversary of the Revolution, and the soldiers who march past the Kremlin walls keep marching, straight out of the square and onto the trucks and out to the front line a few miles away. It is one of the great acts of defiance of the whole war. The situation was desperate. The German offensive toward Moscow had been grinding forward through the autumn, and by early November the leading German units were only a few dozen miles from the city, in places much closer. The Soviet government had evacuated many of its ministries eastward, there had been panic in the city, and it genuinely looked as though Moscow might fall, which could have knocked the Soviet Union out of the war or close to it. The 7th of November was the anniversary of the Bolshevik Revolution, the most sacred date in the Soviet calendar, traditionally marked by a huge military parade in Red Square. Stalin decided the parade would go ahead, in the capital, on schedule, almost within earshot of the guns. It was an enormous gamble and an enormous statement. To hold the parade was to tell the Soviet people, and the world, and the Germans, that Moscow would not fall, that the government stood firm in its capital, that the Revolution and the nation endured. It was also a real risk: a parade in Red Square was an obvious target, and a single German air raid on the massed troops could have been a catastrophe and a propaganda disaster. But it came off. Heavy snow fell that morning, which hampered the Luftwaffe, and strong air defenses were in place, and no German bomber got through to the square. The troops paraded past the Kremlin, past Lenin's tomb, where Stalin stood and gave a speech invoking the heroes of Russia's past, the great commanders who had defended the motherland in earlier wars, calling on the soldiers to be worthy of them. And then, in the detail that gives the day its enduring power, the soldiers did not disperse to barracks for a holiday. They marched directly from the parade, out of Red Square, and went straight to the front, some of them into battle within hours, still in their parade formation. The effect on Soviet morale was immense. The image of the parade held in the threatened capital, the troops marching from the heart of Moscow straight to the fighting, became a symbol of the Soviet will to resist, proof that the nation would not break. It steadied nerves across the country at the darkest moment. And Moscow held. In the weeks that followed, the German offensive, exhausted, overextended, freezing in the brutal Russian winter for which it was not equipped, ground to a halt in the snow within sight of the city. And then, in early December, the Soviets launched a massive counteroffensive, throwing in fresh reserves, including divisions brought from the Far East, and drove the Germans back from the gates of Moscow. It was the first great strategic defeat of the German army, the shattering of the myth of Blitzkrieg invincibility, the moment the lightning war failed at last. The parade on the 7th, held in defiance as the enemy stood almost at the city's edge, troops marching from Red Square to the front, is remembered in Russia to this day as one of the proudest moments of the war, the symbol of a capital and a nation that refused to fall. It is still commemorated every year.

Happy 109th anniversary of the October Revolution! On this day in 1917, the Bolsheviks took over Petrograd , in a surprisingly quiet seizure of power. Overnight, Red Guards, soldiers and sailors took the city's bridges, train stations, telegraph office, telephone exchange and State Bank, organized by Leon Trotsky through the Petrograd Soviet's Military Revolutionary Committee. Meanwhile Vladimir Lenin made his way to Bolshevik headquarters at the Smolny Institute. At 10 a.m. Lenin declared the Provisional Government overthrown. Vladimir Antonov-Ovseenko and Nikolai Podvoisky ran the siege of the palace, which dragged on through the day. At one point the signal to attack was held up because no one could find a red lantern, until around 9:40 p.m. the cruiser Aurora fired a single blank shot. An hour later the Congress of Soviets opened with Lev Kamenev as its chairman, and when the moderate socialists walked out in protest, Trotsky told them they belonged in "the dustbin of history." At 2:10 the next morning, after most of the palace's defenders had drifted away, Antonov-Ovseenko led his men inside and arrested the ministers in a small dining room. For most people in the city it was an ordinary day: trams ran, theatres stayed open, and only a handful of people died. Within hours Anatoly Lunacharsky was reading Lenin's proclamation of Soviet power to the Congress, and by the next evening Lenin was head of a new government promising peace and land. That strangely quiet day led to a civil war and shaped the rest of the twentieth century.

The Netherlands is moving government PCs from Windows to Linux. The Dutch government is building DAWO, a new workplace based on NixOS and open-source software. Eight municipalities are already testing it. The goal is to reduce dependence on Microsoft and other non-European tech providers for operating systems, productivity software and cloud infrastructure. It’s still in the pilot stage, so this isn’t a nationwide Windows replacement yet. But the Netherlands now joins a growing list of European governments actively looking beyond Windows and Microsoft 365. Europe’s push for digital sovereignty is starting to reach the desktop.

El 11 de septiembre de 1973, mientras la Moneda era atacada y las radioemisoras silenciadas, el presidente Allende se dirigió por última vez a la ciudadanía a través de Radio Magallanes. Compartimos íntegramente sus últimas palabras, a 53 años del Golpe de Estado civil-militar.

China has ordered immediate switch to homegrown Linux distros, dropping Windows now. The country's Ministry of State Security has ordered all state-linked entities to stop using Windows immediately, moving up a deadline that was originally set for February 2027. The directive cites "data security concerns" and pushes organizations toward domestically developed Linux alternatives. Two distributions are being positioned as the main replacements. The first is Kylin OS, developed by Kylin Software Co., which evolved from FreeBSD roots into its own independent Linux based operating system. The second is Unity OS, created by Tongxin Software Technology Co., built on top of Deepin, which itself is based on Debian. Both have been in development for years with government backing, waiting perhsps for exactly this kind of situation. China has been signaling this direction for some time, citing concerns about dependency on American technology infrastructure. After the U.S. placed restrictions on Chinese tech firms in recent years, China accelerated its de-Americanization of tech. Note the scale of the migration. China has hundreds of millions of government-linked computer users. Even a partial migration represents one of the largest single deployments of Linux in human history. For context, the Munich city government switching to Linux was considered a landmark case. China doing it nationally is an entirely different order of magnitude. And yes, China is not th only one doing. Europe has been on a similar path, with France, Germany, and several other countries pursuing Windows alternatives over the past decade, driven by data sovereignty concerns and enconmics. Politics aside, I am happy to see that Linux is now being chosen by governmens on multiple continents.
Readers added context they thought people might want to know
The order from China's Ministry of State Security applies to some state-linked entities removing a customized Windows 10 edition ahead of its February 2027 retirement, not all entities immediately dropping Windows. tomshardware.com/software/opera… straitstimes.com/asia/east-asia…

Today is a glorious day: the eminent Sir Roger Penrose celebrates his 95th birthday. He remains as sharp and clear-minded as always. Though he has built his work upon the shoulders of giants, he is, without question, a giant in his own right. @pmiravi @fidbc
Roger Penrose is 95 today. The fire still burns bright.
