I switched to Technitium and I've been pretty happy. Seems very robust, and as a bonus was easy to use it to stop DNS leaks (each upstream has a static route through a different Mullvad VPN, and since they're queried in parallel, a VPN connection can go down without losing any DNS...maybe this is how pihole would have handled it too though).

And of course, wildcards supported no problem.

Maybe take a look at Outline. (Not affiliated, but I host it for myself.)

I also host KitchenOwl, but mostly just as a grocery list.

Nice Dali-esque chair!

Oh thank God it's tobacco, I read it as Tabasco and was very worried.

"While I'm up here I want to shout out all of our friends and neighbors who couldn't be here tonight. Our international friends and neighbors who cannot safely travel to this country. Our immigrant friends and neighbors who cannot safely travel inside this country. Our trans friends and neighbors who cannot safely travel after having their driver's licenses revoked overnight without warning by a cruel and unnecessary legislative act.

"Our friends and neighbors in places like Iran, Venezuela, or Gaza who fear for their lives on a daily basis because of cruel and unnecessary violence. I don't have any plans to stand on this stage again anytime soon, but if I ever were to do so again I would want it to be amongst all of my friends and neighbors, safe and thriving."

I would love to see some enterprising politicians try to pass massive funding for solar/renewable and just call it some stupid nationalistic thing to make it popular with the grey matter-challenged demographic.

Go renewable to save the planet? Fuck off hippie! Go renewable because then we can bomb with impunity? I'm listening...

Never done meshtastic, but I do a little amateur radio. For a high gain antenna, do you just experiment with where it's pointing, or do you point towards something in particular?

The dot-com bubble burst, but...well, it got better.

Of course there were some casualties (famously pets.com), but Microsoft, Cisco, Intel, Amazon...yeah they got their clock cleaned at the time, but long term they were pretty successful.

For all the problems with tech companies, having a chunk of compensation be in the form of RSUs isn't the worst idea ever. (I know it's not specific to tech companies, but it's generally a very prominent aspect of tech company compensation, Netflix notwithstanding.)

To those asking "who celebrated"...Linux was not always well supported by Flash. The promise of HTML5, with first class Linux support, was very appealing.

At this point, they no longer obey the laws of classical physics, and the resulting quantum phenomena — known as relativistic effects...

This is...not how I would word things. Atomic physics is usually not in a classical (Newtonian) regime, and a quantum treatment is standard.

Adding relativistic effects to the quantum treatment is also standard, but many aspects of e.g. the hydrogen atom are reasonably well described without relativistic effects, though of course relativistic effects do matter.

Nitpicking aside, neat stuff!

 

Hi,

I am considering upgrading my router (RB750Gr3). I am eyeing the CRS309-1G-8S+IN in the hopes that the fast ISP in town eventually expand to my street (10G fiber).

My question is about L3HW offloading, and how it plays with PBR. Currently, I have a number of rules (/routing/rule), some based on source IP and some on VLAN. The purpose is to route certain traffic through VPNs (WireGuard, but I run on a separate computer, not on the router itself). Example: VLAN10 routes all traffic through main routing table, VLAN20 routes local traffic through router but sends external traffic through VPN-1, and VLAN30 sends everything through VPN-2. I use a number of different VPNs, so it's not just a binary "main route or VPN."

I am unclear how this plays with L3HW offloading. This page ( https://help.mikrotik.com/docs/spaces/ROS/pages/62390319/L3+Hardware+Offloading#L3HardwareOffloading-Inter-VLANRoutingwithUpstreamPortBehindFirewall/NAT ) mentions pbr-cap/usage/lpm-bank but I am unclear if that's referring to what I'd be using. That page also says that only the main routing table is HW offloaded in the context of VRF, so I wasn't sure if that also applied to PBR.

The question then, is, does L3HW offloading 1) Just Work for PBR /routing/rule, 2) only work via Fasttrack (perhaps requiring some redirect-to-cpu switch rules), or 3) ain't gonna work?

To preempt a few questions: I know Fasttrack is a last resort. I am a single household, I don't have concerns about TCAM exhaustion. I am considering a CRS instead of a "true" router due to cost and reduced energy footprint. I also know that I don't "need" 10G; if it is ever offered on my street it'll be via an ISP with a "best effort" policy, i.e., they don't have throttled tiers, so 10G is their only offering (cheaper than we're paying now for asymmetric cable).

Thanks!

 

What I want: I want to be able to route specific clients through different interfaces (WireGuard tunnels), and I want this behavior to persist upon disconnect/reconnect. Clients can change which tunnel, with several VLANs being able to use the tunnels (so a client A on VLAN 124 and client B on VLAN 789 can both use VPN tunnel X or Y at their discretion).

What I have: IPv4 works fine (routing rule src address -> routing table). IPv6 works, but is not persistent, as clients change their IPv6 address. (I have a dinky script where I enter IPv4 address and country, and it will grab a VPN peer from a json file, set it up, and add the IPv4+current IPv6 address to the routing rules. This works well currently; I use Mullvad.)

Any recommendations? Ideas: use IPv6 mangle based on MAC address, but I have been having trouble getting this to work (extremely slow). Another idea is to have a script run and grab the IPv6 address of client (either by hostname or by DHCP lease+MAC info), but I'm not sure if it's possible to trigger a script upon IPv6 neighbor discovery.

Any help appreciated!

 

People often complain about San Francisco's public transit


and to be sure, it's not perfect by any means (multiple separate agencies doesn't help). But the historic streetcars are pretty neat!

They're painted with the livery of various historic streetcars from all over the country (and a few international, I think). Best of all, they run alongside the modern fleet


same route, same fare.

 

Noticed a few days ago that Sutro Tower's red blinking lights are now white. Just asked them on their website form, but wondered if anyone else knows the story with this.

Personally, I miss the red ones!

Howdy!

I got my Technician in early 2000s, and last year finally upgraded to Extra. Looking to set up a very basic shack.

I'm looking for an HF setup, with most of my use probably using digital modes, but would like the ability to use voice.

Current transceiver is on loan from girlfriend's dad, a Ten-Tec Scout 555


50W HF unit with separate modules for each band. One limitation of this is that the modules set the mode, so it's LSB on 40m, making e.g. FT8 not possible (without some hacking of code or perhaps hacking the module).

Antenna is end-fed with an off-the-shelf 49:1. Currently only have 20m half-wave, but have just enough room for a 40m half-wave in the attic, which is the ultimate goal.

For digital modes, it looks like there are sort of 3 classes of radio:

  • "full digital" where the radio has e.g. a USB port and handles audio, transmit, and frequency set.
  • Some computer-control with RS232, but uses computer audio+adapter to transmit.
  • No digital, use adapter to transmit. This is what the current setup uses (and it works great!)

I'm leaning towards a conventional transceiver, e.g., something from ICOM, Kenwood, Yaesu, (or others) rather than an SDR unit. I'd like the ability to go up to 50-100W if possible.

I don't have a hard-and-fast budget; would like to keep it <$1000 if possible; mostly just looking at used transceivers. Something like a Kenwood TS-590 looks pretty amazing and very "plug-and-play" (but pushing up against price). Something like a Yaesu FT-920 looks pretty feature-rich too; and even something more affordable like an ICOM 706 or even a 725 is probably more radio than I need. Or just grab a new 7300 and call it a day!

Anyway...clearly, I don't know exactly what I want, but figured I'd ask folks with more experience if they have any wisdom. Thanks!
