Since the Black Magic HDMI capture card seems to be the only card that reliably captures audio/video I grabbed an HDMI splitter. Works great, hasn't caught fire...two thumbs up so far.

Towards Reliable Service Provisioning for Dynamic UAV Clusters in Low-Altitude Economy Networks
Unmanned Aerial Vehicle (UAV) cluster services are crucial for promoting the low-altitude economy by enabling scalable, flexible, and adaptive aerial networks. To meet diverse service demands, clusters must dynamically incorporate a New UAVs (NUAVs) or an Existing UAV (EUAV). However, achieving sustained service reliability remains challenging due to the need for efficient and scalable NUAV authentication, privacy-preserving cross-cluster authentication for EUAVs, and robust protection of the c…

Sharing is Caring: Efficient LM Post-Training with Collective RL Experience Sharing
Post-training language models (LMs) with reinforcement learning (RL) can enhance their complex reasoning capabilities without supervised fine-tuning, as demonstrated by DeepSeek-R1-Zero. However, effectively utilizing RL for LMs requires significant parallelization to scale-up inference, which introduces non-trivial technical challenges (e.g. latency, memory, and reliability) alongside ever-growing financial costs. We present Swarm sAmpling Policy Optimization (SAPO), a fully decentralized and …

Resource-Efficient Seamless Transitions For High-Performance Multi-hop UAV Multicasting
Many UAV-related applications require group communications between UAVs to reliably and efficiently deliver rich media content as well as to extend line-of-sight coverage between sky and ground. This paper studies fast yet resource-efficient UAV transitions while maintaining high multicasting performance. We develop a set of analytic and algorithmic results to form the efficient transition formation (ETF) algorithm that deals with different UAV transition scenarios in a multicasting environment…

Nothing I know of beats clubs and hams. I still keep saved searches on all the usual places, but word of mouth is the thing that always works. Almost always around here, if we put the word out that someone needs a reliable and cheap starter, someone comes up with a winner, or even a long-term loaner.
I still comb over swap meets, junk shops, wherever old electronics are piled up. My first HF radio was a dirt-filled horrowshow that cost less than a handheld but I made it work.

2/2 I continued blogging Alberniweather and on FB and Twitter but I gradually removed my personal self from Facebook and eventually during the Pandemic, I decided the Facebook environment was just too toxic even for weather stuff and I shut down my page and left Facebook completely.
The impact on traffic to Alberniweather.ca and its prominence in the community was, and still is, significant.
I have diehard followers, many who have become friends over the years, I still get the odd call from media, or even the public about random weather things.
I have good connections with a few folks at Environment Canada (though their staff have become thinner and more transient :(
and major events still get spikes of local traffic but I since about 2022, and after I removed myself from Twitter that year, I don’t blog nearly as much. I would do a few posts in a week, and then go months without posting. I just got out of the habit I guess.
But I am still interested in the weather. I still feel like Alberniweather is a useful service for people in my community. I still feel a willing obligation to inform people about the weather and I believe I am trusted to do so by the public and local leaders. I’ve never made any money at it, I sold ad space on the website for a few years but it wasn’t worth the hassle and I didn’t feel comfortable taking the money when I was councillor. I have had some generous spontaneous donations at times.
But mainly I do it because it’s interesting, and I hope it is useful for people especially when people are looking for information during a major event.
The highest traffic I have ever had on Alberniweather pre-FB exit was the local Dog Mountain forest fire in 2015.
post-FB exit: the #underwoodfire
People want easy access to reliable local, trusted, information.
Large media orgs have mostly given up on this.
I am grateful we still have an active local newspaper and radio and that both trust me and I trust them.

Multi-UAV Deployment in Obstacle-Cluttered Environments with LOS Connectivity
A reliable communication network is essential for multiple UAVs operating within obstacle-cluttered environments, where limited communication due to obstructions often occurs. A common solution is to deploy intermediate UAVs to relay information via a multi-hop network, which introduces two challenges: (i) how to design the structure of multihop networks; and (ii) how to maintain connectivity during collaborative motion. To this end, this work first proposes an efficient constrained search meth…

The proportion of times that LLMs suddenly fail at something they've done well before seems tailor-made to screw up human reasoning about reliability. If it was 1 in 10 we would know, and be reminded often, to babysit them permanently.
If it was 1 in 1000, we'd rely on them with some reasonable safeguards. But because it's 1 in 100, we get totally screwed up.
The mistake always comes just after you've convinced yourself that "this is probably fine" and …

First test of the pump! Just turned the first pump on to make sure everything works. The regulator works! 100% power seems to draw about 160W. 50% was around 70W. Can't take a reliable picture of the display unfortunately.
I will have to cut the main wire and extend it with a good extension cord so it can reach where I need it to. At least to the little grey shed for now. The controller has to stay dry and in reasonable temperatures.
Not really looking forward to that job. I have cut/spliced/shrinkwrapped wire before but not on a $600 pump. 😬
Today though I will concentrate on hooking up the pipe to the filter to set up a circulation and figure out a temporary situation for the pump controller.
edit: btw the pumps are both Jecod 20,000L/hr varieties. I am hoping (and calculated) that they are oversized so I can run them at 50-75% most of the time.
