  • You can have a lot of smart functionality and remain local-only (e.g., Home Assistant). All my smart devices are on their own VLAN with no Internet access --- if something breaks it's not the cloud's fault, it's mine.

  • What steps do you take to secure your server and your selfhosted services?
  • Fail2ban config can get fairly involved in my experience. I'm probably not doing it the right way, as I wrote a bunch of web server ban rules --- anyone trying to access wpadmin gets banned, for instance (I don't use WordPress, and if I did, it wouldn't be accessible from my public facing reverse proxy).

    I just skimmed my nginx logs and looked for anything funky and put that in a ban rule, basically.

  • Linux is too hard
  • Windows is just as hard as linux, harder even with all the layers of obscurity.

    With Windows, there is 1 current version of Windows (11), 1 "almost current" (10), 1 "outdated but you'll maybe see it" (8.x) and only a few "you'll probably only see this in obscure situations" versions. Linux has as many "parent" distros/package management systems (apt, rpm, pacman, etc.). This definitely complicates things, as each distro family does things slightly differently.

    And we haven't even touched the window manager/DE choices, of which there are a ton (as opposed to Windows). "Combinatorical explosion" maybe isn't the right phrase, but you get the idea --- Debian with i3wm is wildly different from Fedora Plasma.

    This is all a good thing though, as Linux users tend to like the choice and flexibility --- but it does mean that the "right way" to do something on Linux is very dependent on your particular setup, which isn't the case with Windows.

    (I have used Linux for the last 20+ years, and it's definitely my preferred setup, and am lucky enough that I rarely use Windows for work, and never for personal use.)

  • We have pushed on with the project in secret
  • My favorite is Barry Marshall. He thought there was a connection between bacteria and ulcers, which was an unpopular opinion at the time. So he intentionally drank the offending bacteria, got sick as expected, and then people believed him.

    More here, including (which I didn't know until now) cardiac catheterization.

  • Security Breaches Can Be Fixed. People Without Honor Can’t Be Trusted.
  • Why the HUGE, irreconcilable disparity between your front page and the opinion section?

    This is always how it goes, as it should. Horrible opinions shouldn't affect the reporting; and horrible reporting shouldn't affect the opinions. Different publication, but https://newsliteracy.wsj.com/news-opinion/

    It's best IMHO to think of them as two completely separate entities.

  • uhhh overleaf you say
  • I was writing up my problem set answers once, and it involved the (complex analysis) residue. I wasn't sure if there was a shortcut (as opposed to \mathrm); googling latex residue did not produce the search results I was hoping for...

  • Cloud services and hardware alternative
  • I'm curious what you're doing on an SBC that explicitly requires x86, though?

    Not parent, but I used ARM SBCs for a bit, and while it was nice, my x86 experience with a nuc has been much, much better. HW acceleration works on some RPIs, and sort of worked on my Orange Pi 5+, but only when using an ancient kernel which had some hacks (like, kernel debug messages saying "DISABLE THIS FOR RELEASE!"). And afaik RPI 5 doesn't support hw encoding (not to mention no SSD support).

    Basically, my experience was that the hardware was neat if sometimes limited, the energy consumption was great, but the software/kernel support...ugh. YMMV of course.

  • Cloud services and hardware alternative
    1. Certainly depends; and it depends on traffic volume!

    2. Definitely something to consider; many folks (myself included) use a free/cheap VPS as the endpoint, and reverse proxy to home, via some VPN (WireGuard in my case). Works well, and lots of guides online.

  • Anyway, here are terminal commands you don't understand.
  • And many folks have headless setups --- raspberry pis, home servers, VPSs, etc. It's kinda overkill to install a desktop environment on a headless box if the only reason you need it is so you can VNC into it for a simple task that could be done over ssh.

  • Trump strips Biden-era Cubans, Haitians, Nicaraguans, Venezuelans of humanitarian parole
  • I for one am glad this demographic got exactly what they voted for.

    Emphasis mine.

    The problem is that "they" did not all vote this way. Yeah, I too am glad that the Trumpers are getting their comeuppance --- fuck them. But your rhetoric is a bit extreme and devoid of empathy.

  • You just gotta think different
  • For some (most?) of us, we don't have ssh access open to the world, so everything is over a VPN. So I can just use NFS over WireGuard which afaik is fairly secure, if you trust your endpoints, and works great over the Internet.

  • San Francisco's historical fleet

    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.

    Sutro Tower lights changed color?

    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!

    Recommendations for first HF rig?

    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!
