Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

New FCC standards should consider latency
Sorry, I think you are thinking of something else. Maybe a railroad crossing (:-))
Joking aside, the https://www.waveform.com/tools/bufferbloat test looks to see if the networking software is working correctly by putting a large load on the network, and then seeing if other streams are affectec by the overload.
The example on the https://libreqos.io/ home page is of

TCP's congestion control saved the internet
fq_codel was successfully offloaded in a few products, however, no offload here, just a xeon with a ton of cores and a big L3. On the libreqos case we leveraged some ebpf to do packet steering in what we call the heimdal bridge, and also kathie nichol´s wonderful passive ping concept: https://github.com/thebracket/cpumap-pping
src here: https://github.com/LibreQoE/LibreQoS/
You can get a transparent high speed bridge with shaping capability up pretty rapidly with supported hardware.
I still long for an ethernet card that can do a trie lookup natively! The flamegraphs are mostly getting the right packet to the right cpu, still.

SpaceX no longer taking losses to produce Starlink satellite antennas
That's doable. The HOA doesn't sell internet. Just pays for a Wi-Fi network that happens to reach you.
I'd advice two high performance dishes (dishes are known to fail and support is an issue so one on standby while waiting) and a business connection. You'll need a third party router with fair queuing, protocol and service speed shaping etc etc. I'm sure both openwrt and opnsense will do. But check this out https://libreqos.io/

A dilemma of choice
Still, ya know, a modernized kernel on the devices is a start, better wifi, also, and if they do get arround to adding at the very least driver support for the linux BQL or AQL subsystems, and apply fq_codel, or cake, they could certainly manage the uplink better. At the higher rates supplied by the link, the wifi becomes the bottleneck for which solutions appeared in the Linux kernel in 2016. There has been some good research on actively managing the link via the sqm-autorate project, and multiple middleboxes such as those from preseem (fq_codel), and my own libreqos.io (cake) , might be able to manage the downlink better with the addition of link level stats, at very minimal CAPEX per subscriber.

UK users all need to complain to Ofcom for being mis-sold Starlink
Also, people would notice starlink going to hell less often if starlink would just deploy libreqos.io.

[GN] Strange AliExpress Motherboards with Built-in CPUs: Erying Skyline & Polestar
With dual 2.5 Gb/s and Alder Lake single-thread perf, I was thinking high-end latency-optimized QoS/Firewall for gigabit internet. CAKE and LibreQoS would love this thing.

Bufferbloat and NBN FTTN. Is it normal to only get a C rating on a waveform test across 3 modem routers?
It is so wonderful to see so many happy SQM users all over the world. That said, do you think NBN might consider installing libreqos.io to benefit all their other users one day?

SQM (optimizing for videoconferencing and gaming) on the current eero products
I am curious as to the availability and functionality these days of the fq_codel option on the eero 6 and eero 6 business? When I last paid attention about a year ago ( https://www.reddit.com/r/eero/comments/u7xm83/gen_2_sqm_vs_gen_3_sqm_stick_with_gen_2_if_you/ ) only the gen2 had cake, and a lot of folk struggled with correct behaviors at +500Mbit with the 6's implementation of fq_codel. (The +500Mbit problems kind of indirectly spawned the libreqos.io project, which pushes the inbound shaping to a middlebox at the ISP) Anyway, did it get better? Does RFC3168 style ecn work on the wifi?

[Tutorial] How to setup SQM QoS for GeForce Now on OpenWRT routers with Cake for no packet loss and frame loss
You probably already know this, but the team behind Cake SQM are pushing to get ISPs to implement the free LibreQoS on their side, so that many more users could benefit from SQM: https://libreqos.io/

How can we convert a DMR signal into clear voice by RTL_SDR?
I have no experience with DMR myself, but my understanding is that the Boatbod fork of OP25 has experimental DMR support, and I believe SDRTrunk software does, too.

Ask HN: What weird technical scene are you fond/part of?
Using OP25[1] with RTL-SDR dongles to implement scanners for trunking P25 radio systems on a computer. And as a sidebar to that, listening in on geographically remote public safety radio systems using Broadcastify[2]. It's basically the old "radio scanner" culture, but taken online and distributed worldwide. People listen to all sorts of stuff, but given my background as a former firefighter and former 911 dispatcher, my main interest is listening to public safety dispatch stuff.
That said, another commenter below mentioned modern "phreaking" and how it's become more radio centric... and while I won't admit to doing anything illegal, let's just say that there's some interesting stuff you can do / look at / listen to these days, especially with ubiquitous and inexpensive SDR hardware and related resources. See the recent story about the KrakenSDR passive radar stuff, and some of the papers that are out there about P25 security flaws, some of the automobile hacking stuff that's RF based, etc., etc. There's a fascinating world out there buzzing around on invisible electromagnetic fields... and you can tap into it with a $30 dongle and a Raspberry Pi (or your PC).

Is this encryption or frequency hopping or just not FM modulation? Not law enforcement, just a school they use Motorola handhelds.
If it's P25 Phase I or Phase II then SDRTrunk might work. boatbod's op25 might be another option, but more complicated to set up.

I don't have a full guide for you, but I use https://github.com/boatbod/op25 for receiving and decoding P25 Phase 1 digital signals on the command line.

How can I hear the Franconia, VA (Fairfax Co) Police, Fire, EMS scans? Unsure if there is a specific open mhz link for them. Thanks!
If you are handy with Linux you can use an RTL-SDR and OP25 on a Raspberry Pi or really any PC. This is the page for the Fairfax trunked system https://www.radioreference.com/apps/db/?sid=6957. Any talkgroup with mode D can be listened to, mode DE is encrypted. If you want I already have config files made up for the police dispatch and fire/ems dispatch channels.
