TEMBA BAVUMA. The greatest South African captain by miles. Before this test series he was unbeaten as captain in tests but his team got defeated, mocked by opposition in the first test. He didn't say a word. He waited and replied with a marathon 179 with the bat, took his team's total to 425 from 110/6. Then bowled out them twice in a match where almost 150 overs vanished due to rain. Then the third test. After a brilliant start, they could manage only 329 and conceded a lead of 100. At the end of day 3 they were around 140/4 which means 40/4 in the context of the game. His team fought back on day 4. Took the lead to 280. And then on the fifth day his bowlers ran havoc through the Aussie batting line up. Two matches, two generational comebacks and this man won't stop here. What a leader. 🐐❤️ #SAvsAUS

Be like @ashxhart The person behind TensorFold. > Grew up in the UK > Spent 7 years in tech support > Joined a friend’s food delivery tech company > Spent 2 years there as a PM > Went back to his first company as Head of Technology, still there today > 15+ years across software, DevOps, AWS, networking and cybersecurity > Became the 4th-line support guy, the one you call when nothing else works > Started exploring AI on the side > Spent 6 months building a local inference engine in private > Archived it three times > Launched TensorFold anyway, expecting maybe 5-10 users > It blew up in the first few days of launching > 1.5k+ stars on GitHub > Top Local AI builders started contributing > Rewrote it in Zig with the community > Built MCDMA so Macs and NVIDIA boxes can share memory > Linked two Mac Studios over Thunderbolt 5 > Shipped a model that keeps learning while you use it > Got a DGX Spark donated to keep building TensorFold > Went from 300 to 9k+ followers in 4 weeks > Called on the UK to build its own open model And the story’s far from over. We need people like Ash to push forward Local AI and Personal AI. Truly an inspiration! Follow him, you will thank me later. Honored to partner with him to make TensorFold part of the @YukonResearch challenge.
The local community is absolutely on fire with the @darkbloomai @yukonresearch @eigenlabs TensorFold Challenge. CUDA is heading for 200% 🤯 @GumbiiDigital @0xkydo @TheDavidTai

TensorFold 1.2.0 is here! Once release a day keeps the doctor away.
TensorFold engine 1.2.0 is out 🙌 Qwen3.8-27B with MLX 4-bit weights and DFlash2, compared with 1.1.9: • M3 Ultra: 14.4% faster decoding with one stream, 44.2% higher combined throughput with 16. • M5 Ultra: 5.8% faster decoding with one stream, 25.2% higher combined throughput with 16. New support includes: • MiniMax-M3.1-Flash on Metal. • NVFP4 Qwen3.6-35B-A3B and dense EXL3 Qwen3.8-27B on CUDA. • Gemma 4 E4B on Intel Arc Pro B70. The measured speedups kept matching tokens. Qwen-VL image replies can differ from 1.1.9 because image preparation now matches the checkpoint's own processor. Huge thanks to everyone credited in this release: @bhcc2025 @Bizuayeu @diwakergupta @jvr0x @jayleaton @joshuaswarren @woolsey @petruspennanen @volatilemarkts @MiaAI_lab @plotarmordev And on GitHub: AbrahamCete, akol1, alexderz, Arminova, BadAd84, BlivionIaG, BobClawblaw, fche, gilby, jrb-ai, jschmied, laudney, Mirrdhyn, mrv777, ppardus, simon-lin88, ThomasHalwax, valacroix and wojo. Thank you for the PRs, reviews, testing, bug reports and hardware access. The time and knowledge you keep sharing with TensorFold mean a lot to me. Apologies if I've missed anyone. tensorfold.dev

South African series are always so enthralling. Need to find a way to make it 5 matches in the future. 3 has never been enough.

Before Geoff Crammond cemented his legacy with Formula One Grand Prix in 1991, he let us have a peek at what was to come with the 1989 classic Stunt Car Racer. Revving up the engine before you even hit the ground, breakneck speed jumps over monster ramps, and the iconic “kkkkrrrrrrrrrkkkk” sound whenever you hit the road too hard and the car’s frame cracks a little more. An absolute staple from the golden age of home computers!

Of all the vulnerabilities (CVEs) published so far in 2026, 4% have been reported as exploited in the wild (by @VulnCheckAI ). The last 2 years, it was 7%.

You don't need to ingest a CSV to test a KQL detection on it. Give the CSV the real table's name with one let line: let DeviceProcessEvents = externaldata(...) Your query runs on the file unchanged. Read-only, nothing loaded. I ran my 6 AnyDesk hunt queries on a public lab bundle this way. All 6 returned rows.

My opening presentation from today’s @unpromptedconf, in SF. Self heal from attacks, “solve” AppSec, and rethink threat intelligence. All, in discussion how to be, and stay, “AI native” through our hobbies. In my case? Vuln research. docs.google.com/presentation…
