During yesterday's LibreQoS APNIC webinar, I posed the question: won't more bandwidth solve these problems? As Herbert Wolverson said, yes, more bandwidth is good, but, still these problems remain if queueing is done incorrectly. Here's my take on why bandwidth alone is not as good as bandwidth good queueing policies: Generally it was believed that 'data is important, so don't throw it away; hang on to it and send it later'. In practice, this has proven to be suboptimal as two issues may emerge: 1) latency increases for some flows due to heavy demand from other flows using the same bottleneck link, 2) even a single flow can have excessive latency due to aspects of typical TCP behavior (referred to bufferbloat) when the buffers grew large enough that the data being buffered was retransmitted anyway. It turns out that not all data is equally important. Active Queue Management is the art of deciding priorities, both in deciding what data to throw away, but also in allowing some later arriving data to be transmitted ahead of data in another connection that arrived before it. These problems have been studied, and good solutions have been found by using certain queueing policies in routers and switches, referred to as “fq_codel’ and “cake”. These track the different flows not by classifying the data, but by watching the behavior. Flows that send relatively little data (DNS lookups), or at a measured pace (video chat) have priority over flows that send a lot of data as quickly as possible (App and System updates, Video and ISO downloads).

There is so much that is so damn impressive about Nominal's execution. The team identified a truly needed product in the world. More than that... They serve their customers. Sometimes Nominal is saving days of work for an engineer detangling the performance of new hardware in an autonomous fixed wing drone. Other times, helping implement a transformational change for engineering orgs, delivering iteration speed from simulation to range to unlock an RFP goal and contract win. They are building dual use -- powering the best of commercial and public sector teams. Whether a government contractor delivering on a $12b contract. A scaled public company, integrating AI into your roadmap on to your existing HW platform. A startup which is willing a first product into existence. Nominal is there for all the dual use hardware builders who live real time, live in physical world time. The real world runs real time. The real world runs Nominal and so excited to be on the journey. Also, hiring, https://www.nominal.io/, kind of a lot. If you are awesome, they want to talk to you.

Integrating advanced tech into military gear like jets can seriously ramp up performance and effectiveness. It's about the necessity of staying ahead in a world where tech evolves at warp speed. In the military, like in many tech-heavy fields, staying on top means constantly adapting and improving. That drive for the latest and greatest is all about survival and maintaining superiority. My push for using the F-22 over the F-15? It's based on seeing firsthand how vital advanced tech can be in high-stakes scenarios. When you're up there, the confidence you have in your equipment can make or break missions. It's a lesson that's pretty universal, whether you're in the air or on the ground in any high-tech field: always innovate, always adapt, and trust in the best tools at your disposal to get the job done. #fighterpilot #f22 #f15 #fighterjet #airforce #aircraft #aviationvideos #aviationgeek #reels #joshgunderson

WAYMO: THE BIGGEST SUPPLY CHAIN TECH INVESTMENT OF THE YEAR The supply chain technology markets are heating up. In the biggest transportation tech investment of the year, Waymo just announced a $5.6 billion financing. The investment, led by Alphabet Inc. (which owns the majority already), also included Andreessen Horowitz, Fidelity Investments, Perry Creek Capital, Silver Lake, Tiger Global Management and T. Rowe Price. Waymo will use the capital to pursue leadership in the autonomous vehicle arena, with a focus on its Waymo One robotaxi offering. Would you get in a self-driving taxi? Most people don't realize this, but there are already 100,000 weekly trips in San Francisco, Los Angeles, Phoenix, Atlanta and Austin. I predict robotaxis will be in most major markets within 3 years. What other winners are you seeing in the autonomous transportation arena? #supplychain #transportation #tech #autonomous https://lnkd.in/e8HAhReY

Who doesn't love chatting about the frontier of Space?! Loved getting this insiders look from Epsilon3 CEO Laura Crabtree (ex-SpaceX, Northrop Grumman) as the industry reshapes into a lightening fast startup ecosystem for us to marvel. Small teams are lowering the cost to access space. Homegrown automation software is dramatically reducing team size -- as Laura puts it: "You won’t see 50 people in a control room for launch…you’ll see 5 controlling 50 different assets and a couple of 100 assets that are mostly operating on their own." Personally i'm keeping a close eye on the new interconnectedness between space and the broader economy will spark a flywheel of innovation. 🎙️ Listen in to our discussion (link in comments) as we release today -- 5YF#16: Space command reimagined, automating mission control, new deep tech hubs, interstellar missions, and the future of space operations w/ Epsilon3 CEO Laura Crabtree To infinity!
