@jrssnet That checker was great. the dmarc one, not so much. We'll see in a week if I get any reports. Thanks again for what you and the crew do to spread good, useful knowledge.

@tab126 I usually use MX Checker for this kind of thing, but there are a ton of free online validators. If you can't find exactly the kind of validator you're looking for at MX Checker, explore your favorite search engine. mxtoolbox.com/spf.aspx

@jrssnet Thanks for the advice to lock down spf and dmarc records. I could verify spf, but I'm not sure if the dmarc tool is buggy, or if I did something wrong. Do you have a suggested tool to verify my record expresses what it should (ie, reject everything)? Thanks!

@decentespresso ever consider making an air fryer? I would love to have customization of heat application. And most are disposable unpleasantness.

@jrssnet I like that idea. ionotify -> something like a redis on file touch. Put a TTL on the key, and use an event to fire back to delete the file. The context is that I want an S3-like policy for file retention/purge. Logrotate isn't quite cutting it.

@tab126 No, I haven't. What you'd need for that is, essentially, a block pointer tree of datestamps. What you probably really want is a NoSQL database instead of a filesystem, for whatever task this is that specifically needs to revolve around dates at a massive and ongoing scale.

@jrssnet Have you ever seen a filesystem that can purge files after X days.. or efficiently tell me files older than X? ionotify is an interesting start, but has downsides. Using 'find' consumes 2x iops. I think this might just be a "hard" thing to do...

@FrameworkPuter A modular docking station? Or a printer that expands to have a scanner?

What would you like to see from us in 2024?

@levelsio And absolute humidity, not relative humidity.

@levelsio Radon. Fast and long term sensors have been very informative.

What sensors you want an air quality sensor to have? AQI, CO2, what else?

@jrssnet Many thanks. Seemed like a lot of copying, so I took another route with golang's fsnotify package. I've got auto-deletion of files working. Need to integrate OPA/policy and some enumeration from before the process starts. github.com/sweeneyb/file-… if interested

@tab126 Not exactly, but also not NOT exactly. What you probably want to look for here is "zfs redacted send." I described it briefly when I covered the release of 2.0 for Ars Technica, but I've never used it in anger myself. For more details, try the PR notes: github.com/openzfs/zfs/pu…

Hey @jrssnet, does #zfs have retention/purge policies for files (not snapshots)? or is there a better place to ask? I found an oracle doc, but more curious about the OSS version of zfs. Pref linux. Thanks!

@LeeLKennedy Yes. Exactly. fortune.com/2023/02/15/elo…

Pulled up Twitter this morning and the tweets went (I'm not joking): 1. Tweet from friend (👍) 2. @elonmusk 3. Ad 4. @elonmusk 5. @elonmusk 6. @elonmusk 7. @elonmusk 8. Ad Seriously? Is this guy just boosting his own tweets? I don't care about him anymore.

@jrssnet @cataclysmza @opnsense Am I wrong for not wanting to conflate wifi and other network services? The "router" is already doing a lot with dhcp, dns stuff, firewalling, routing. Quite happy with discrete APs.. configuring wifi well is hard enough without the other bits.

@cataclysmza @tab126 @opnsense OpenWRT won't fix the wi-fi chipset firmware, though, which is still mediocre at best. See above re: results under heavy load.

Hey @jrssnet, do you have a decent home router (no wifi) that you like? Had my 2nd router (brand starts with a U) die in 5 years. I think you've suggested another brand on 2.5A? Many thanks!

@jrssnet @opnsense Ever put an LTE card in one of these? Looks like the Qotom could take a half mini PCIE LTE card. Might be nice to have some backup not on a different SSID

@jrssnet @opnsense That looks awesome. Looks like there are a couple of terraform providers to help in case I need to paperclip it, too. Is there any real difference/worry between opnsense and routerOS?

@jrssnet @opnsense Thanks. Definitely something I would have passed over. Would love to play with opensense and take control, but will have to check the lab budget. Small multi-nic x86 box are more expensive than I would have expected at the moment.. Thanks again

@tab126 There's really no such thing as a consumer router without wifi anymore. You just disable the WiFi if you don't want to use it. I like Netgear Nighthawk in the consumer space. Next step up: @opnsense running on an inexpensive small form factor PC with multiple NICs.

Thanks, @particle. The service that comes with a Photon is great. The "OS"/"firmware" divide with OTA updates made what could have been a tedious project extremely easy. Finished the project while at a mechanic getting things fixed. Awesome.

@FrameworkPuter Today, one of my monitors started going into power save. I've had both hooked via usb-c on the left. They both work when one is on the right, and the other is on the left. Is that a failure mode you've seen? Seems unrelated to the cards (i swapped around)

@FrameworkPuter Televisions. Printers. Washer/dryer. HVAC.

When we say we're remaking consumer electronics, we mean all of it (eventually). What products beyond laptops do you want to see upgradeable, customizable, repairable versions of?

A question for #infosec twitter: How do you practice and evaluate tools? Is part of the background/training understanding how to safely bring in payloads, isolate networks, etc?
