  • Roofs are not good places for solar panels, I’ve heard. I’m struggling to recall exactly why, but I think it’s factors like if you have sun-tracing motors, they are normally installed on a pole which is top-heavy with a motor. The pole penetrates into the ground quite a bit. And when there is a hail storm you want to be able to cover up panels which requires quick access. So in short roof installations make sun-tracing impractical especially if the roof is pitched.

    The article did not give any detail on /why/ a vegetated roof is better for heating and cooling the home, but I would expect the plants to effectively add to the insolation in the winter and in the summer there would be an evaporative cooling effect on the roof.


  • pcregrep is not automatically installed with Debian but it’s in the official repos. It seems common to get:

    pcregrep: Too many errors - abandoned.
    pcregrep: Error -8, -21 or -27 means that a resource limit was exceeded.
    pcregrep: Check your regex for nested unlimited loops.
    

    But it will help in many cases. I can see that it works on sufficiently small files. I noticed the built-in grep function for emacs can be modified to use pcregrep w/-M added instead of grep, which I find quite important because emacs makes it very easy to jump around to visit different results. In the end it’s still a hack.


  • I currently use the find-grep function in emacs, which is basically: find . -type f -exec grep 'my.*search.*pattern' {} +

    To do PDFs, I use something like find . -type f -iname \*pdf -exec pdfgrep 'my.*search.*pattern' {} +

    My problem is generally when TOKEN1<space>TOKEN2 has a line break between tokens. It’s fucking annoying that grep is line-by-line. I wonder if Hister solves that problem. But from the website, I see no advanced syntax. I would love to search a pattern like word1 w/s word2, which would find cases where word1 and word2 appear in the same sentence. And word1 w/p word2 to match cases where two words are in the same paragraph.


  • Set it to make the Wi-Fi an open access point. Set it to rotate through a list of SSIDs like:

    • “Find a more ethical shop than Wal·mart”
    • “Watch out for Walmartians”
    • “It’s ethical to shoplift evil brands (Nestle, Coke, Pepsi, Kraft, Unilever, P&G)”
    • “Never show your ID to ICE agents”
    • “Learn Spanish. Fuck republicans.”

    Then find a way to hide it in a wall at Wal·mart, wired to power. (edit) Maybe clean every hair follicle from the keyboard first, and wipe your fingerprints.

    Perhaps have a captive portal but with no uplink. One that just redirects to a web server running on the laptop that shows content supporting whatever ethical cause you want to promote.




  • Consider self-hosting HALF the service. Something like this:

    Outbound

    local Postfix on dynamic IP → relay (optional and configurable) → recipient

    You can configure Postfix to use a relay depending on the recipient. E.g. if you need to reach alice@outlook.com, MS will reject your dynamic IP. But if you have bob@outlook.com, you can tell Postfix to relay via MS servers using your bob@outlook.com account for all *@outlook.com recipients. And yes, you can still use a different vanity address in the FROM: field, like Gobbel2000@nerds.org, if that’s what you want to be known as. You can freetype whatever your want as the FROM: address if you use a good MUA like mutt.

    You can even hack postfix to send over Tor. And you can make it possible to support *.onion email addresses, which is something that no non-self-hosted service offers.

    When I email someone for the 1st time, say it’s [email protected], I first configure my mail server to relay to @someunknownneverseensvc.xyz over Tor. If that fails (and it often does), I configure Postfix to directly send to that server from my dynamic IP (or VPN if I have that running). That’s the default, in fact. If that fails, then I can cave-in and compromise my privacy by relaying through a 3rd party, if I choose. Most importantly, I am in control. If I really want to send the msg but I really do not want an additional MitM, I may be able to create an acct on @someunknownneverseensvc.xyz and then use that as a relay to recipients on that host.

    Rise-up has an onion SMTP server. So if you have a riseup acct you could use their onion as a relay.

    Inbound

    (your acct @ rise-up or disroot.org or danwin1210.de or autistici) → POP3 onion using fetchmail → local Postfix → dovecote or procmail → local files read by your MUA of choice

    You avoid a lot of complexity and labor by not maintaining a WAN-listening server. Though you still have a fair amount of effort in configuring your junk, you need not do all the configuration up front. You can do it on a piecemeal per-outbound msg basis to spread your config effort out over time. Of course you need to use a forwarding service or do some DNS arrangements if you want an address that does not tie you to an ESP.

    This approach relieves you of the reliability problem… you need not maintain a server always online, up, and listening. But of course you lose some privacy because all your inbound traffic is seen by your ESP. At least you can potentially circumvent your ESP on outbound mail.

    BTW, you might want to crosspost to [email protected]

    (update) my complaint with Postfix: no Tor support out of the box

    Postfix needs some hacking to get it to work over Tor. As old as Postfix and Tor both are, they should work together out of the box.




  • It’s an old story. I don’t recall exactly what happened after I pushed back. I certainly was not fined and IIRC the city got off my back because they had no case.

    I eventually landscaped by choice. I don’t recall the motivation but I think it was to exploit a rebate offered by the government.

    Then years later weeds (ugly plants) emerged again because the weed blocker that was under the landscape was compromised. Neighbor was on it and I got cited. I then noticed one of the plants actually was a weed (or resembled one), legally. So I had to pull them. I acted within the deadline so there was no fine. I was bummed because I really wanted to give the neighbor the middle finger.





  • I vaguely recall that there are good and bad ways to dump it in a landfill. You can bury it well, but the rot creates methane gas pockets just below the surface which escape into the atmosphere when dug up. When it’s rotting on the surface, it gradually leaks methane as it’s produced. Though I think it’s less rot when aired out. Mulch likely has ~½ the surface area against the soil and rotting there, so I would expect notable methane in that case.

    Anyway, I’ve read nothing specific on it but conjecture that it should be studied. All that work capturing the carbon into tree wood only to cause the emission of a much worse GHG.


  • I see no mention of GHG. Tree services often cannot find a use for the trees they cut down (which is strange because you would think they could mill it and sell the lumber). In the end, they dump trees they were paid to remove into landfills. When trees rot they release methane gas, which is 10× worse than CO₂.

    I bring this up because wouldn’t wood mulch have the same problem?

    This is extremely reductive and oblivious to the actual realities of banking in various countries.

    I think you will be hard-pressed to find a country that does not have a single bank that can serve those w/out smartphones. If you find such a country, plz post about it in [email protected] and send me the link. Then we may be able to make a case for ppl in that specific country not being boot-lickers, if at the same time being unbanked is illegal.

    If you think it’s easy to be “unbanked” then I would suggest that you try it yourself first.

    I have been simulating an unbanked life for years now. 5 creditors are threatening lawsuits for non-payment after refusing my cash. One took me to court and it was an easy win for me. I just appeared without a lawyer and pointed to the law.

    It’s also worth noting that unbanked is more extreme that simply choosing a bank that does not require a smartphone.

    It’s banking:

    https://slrpnk.net/post/28294479

    The army of corporate boot lickers in the mobile phone context is largely composed of people who think banking on a smartphone is wise, despite the attack surface and despite the bank being empowered to monitor their customers more closely. Banking apps are the most significant culprit for gluing people to Android.

    We may never see the day when more than 5% of the population realises the importance of FOSS enough to shake free of their addiction to convenience.
