Hidden chokepoints

One of India's biggest digital vulnerabilities sits on a six-kilometre stretch of Mumbai's Arabian Sea coast. Around Versova, a densely populated neighbourhood on the city's northwest, at least 13 of ++India's 18 intercontinental submarine cables++ come ashore within six kilometres of one another. Together they carry as much as 95% of India's international bandwidth to Europe, Africa and West Asia. "This network faces a…

The price of Trump's stupidity

Iranian officials have said the war won’t end and shipping routes won’t reopen until all of the conflicts in the region are resolved. Gulf states that had hoped for a quick end to the war are now grappling with the realization that the U.S. has pulled them into a conflict that could run for years with no clear strategy for ending it.“This isn’t just a Yemen story,” said H.A.

There is still Alpha to be had in good training data.

Post-Training PipelineIn this release, we refrain from introducing novel post-training algorithms. The overall recipe follows the standard paradigm of supervised fine-tuning (SFT) followed by reinforcement learning (RL) and on-policy distillation (OPD) [Gu et al., 2024; Lu and Lall, 2025], without algorithmic modifications beyond well-established practices. Instead, our efforts are concentrated almost entirely on what the…

DeepSeek V4.1 Flash Vision is surprisingly good

I was just testing DeepSeek V4.1 Flash on a bunch of vision tasks with old book pages, and it’s not bad at all. It had issues with some Sanskrit type and diacritic-heavy text, but it still managed reasonably well. And considering the cost, it’s pretty impressive. During off-peak hours, the API is dirt cheap. That…

We are the stories we tell

"To poison a nation, poison its stories. A demoralised nation tells demoralised stories to itself. Beware of the storytellers who are not fully conscious of the importance of their gifts, and who are irresponsible in the application of their art: they could unwittingly help along the psychic destruction of their people."
