  • When eventually washed off, the aerogel is handily broken down by soil microbes.

    I am not going to claim to be an expert on any of this BUT that wording sounds suspiciously like bullshit. Maybe it’s not, but it’s one of those phrases that sounds like when vitamin companies claim that more B12 has shown to fix whatever ails you. Or “our plastic is environmentally friendly: 100% recyclable, and breaks down into teeny micro-particles over time, and gets absorbed by the sea life like ordinary sand…”



  • I have had two tech jobs like that, even before COVID, starting in 2016. The first time, it was a company that outgrew their workspace. They put us in ‘rent-an-office’ spaces for a bit, and then my boss started working from home a few days a week. Then he allowed me to. We moved to a new office, but it was always empty in my section. That was fine, too, but the commute was terrible, so I started doing 2 days a week, then once a week, then a few times a month. I rarely saw my other coworkers in person, and nobody said anything aloud.

    The next job started because of COVID, and when they started doing RTO, they also wanted to do “hot desking” (no assigned seating) and open office plans, and I was not having that. I was not going to work in a “cafeteria” like setting. So I got contracted work and have worked from home 100% for several years now. Nobody has office space, and we work all over the world to collaborate. I get paid very well.

    I hope i never had to go back to an office. I reach retirement age in about 15 years, and I am hoping to make it.



  • Having moderated forums back in the day, I can answer to some of that motivation.

    First, some people are just bullies. A sense of tribalism forms around bullies, who feel the need to act out and repeat the abuses they have endured. Hazing stems from this, too. Cruelty masked as “you should know better,” advice. Given too late.

    Some have a smug sense of superiority, and want to keep it that way. Less smart people means they stay king of the mountain. Others are scared their own lack of knowledge will cripple them if they don’t keep the potential competition down. Insecurities drown out any sense of empathy.

    Some people hate themselves so they punish others in retaliation. Like, trying to erase past cringe by making others hurt to even the score.

    A few are sick of “the same fucking newbie questions again and again and again,” but still hang out in newbie forums for some reason.


  • really just doesn’t do what I needed to do.

    This has been my experience, or sort of does what I want it to do, but I have to rethink what I need it to do instead of something really simple. Like a “new type of shared file system” that replaces NFS/Windows sharing. So instead of files in a standard file system one can manage with a file browser, it has “indexed” your files in such a way that the actual files are renamed into data chunks, and one “finds” files by their non-intuitive search engine that can’t do even basic search engine tricks like “AND/OR” searches, wildcards, and the results are hit and miss. “But it’s faster and more elegant!” So how do you restore from backup when the system fails? “When the system does whatnow?”

    Yeah, no thanks. I can recover files from a file system much easier than some proprietary encoded bullshit fronted with a bad search engine over a proprietary and buggy index.





  • Being poor. In college in the 90s, my lead sysadmin couldn’t afford Minix for this system we had, so we tried to compile Linux on it. Three days later, we still failed, and gave up, but this was kernel 0.93 or something, so it had a ways to go. But I learned so much from that experience without paying for a university course or something.

    Years later, I bought a copy of Red Hat 6 at a Costco. Windows 95/98 was big, I didn’t know how to pirate it, so I went back to Linux and it worked great on my “franken-puters” cobbled together from spare parts dumpster diving. Steep learning curve back then, though. Then I brought it to my workplace, went from UNIX admin to Linux admin, and soon I preferred it to Windows. Been my daily driver for decades, now.

    Am I an evangel? A little, but I find that “right tool for right job” is a better approach. Linux is great for everything, BUT a comprehensive system like MS Office AND Active Directory simply does not exist in FOSS space yet; everything is cobbled together and a kludge still trying to catch up.

    Obsessed? Kinda. I just assembled some ansible scripts to roll my own distro. Why? To see if I could.


  • I worked in a job with build scripts. Developers would list what they wanted in a drop-down menu on a website, with very few “fill in the blanks.” This would create a template, which was sanity-checked.

    One of the “fill in the blanks” was “home directory of user, if not default /home/username.” Some people filled it in, some didn’t. A lot of “users” might be apps with /home being “/opt/appname” “/var/www/html” or something. We checked to make sure that directory existed, if not, create, and set permissions. Easy peasy, all automated. Ran this lots of times.

    Then one day, the script failed. Borked the whole box. Sometimes the VM was corrupt, so delete VM and try again. Usually worked. But this time, the build kept failing. The box went down. Wasn’t even bootable. This happened several times with this one build. So we mounted the borked drive under a new VM and checked out the logs. Just like the dessert stage of Willy Wonka chewing gum, it always failed at the last stage: making /home directories.

    It would create them, then halt that it could not find bash. We looked for bash on the bad drive, and it was the usual /bin/bash shortcut to /usr/bin/bash and we were truly puzzled. I did a chroot to the drive and NOTHING worked. It just hung. That was the first clue.

    The second was looking through the build script (in bash, which we didn’t write) and checking the steps. Looked it the logs. Always died at creating some user named sapadm, the user for the HANA database. Eventually, I checked the configure file, and noticed it was the only user with the odd home directory “/usr/sap.” Then it hit me: the permissions.

    The script, thinking it was a home directory, did a chmod - R 755 for all directories and chmod - R 644 for all files! That meant, while creating home, it made everything under /usr not executable anymore! Holy shit, no wonder nothing worked! So we commented out that user in the config, ran the build again, and we were good! We created the sapadm by hand, and then later fixed the bug in the script.

    SANITIZE YOUR DATA. Or you might turn Violet Beauregarde into a blueberry.






  • Maybe not the same, but a knoppix CD was part of my toolkit for field work for many years. Stuff I did with it:

    • Retrieve or fix data from systems that could not boot.
    • Scan systems infected with boot viruses (clamscan), and wipe entire drives if necessary
    • Test various network issues: DHCP, DNS, tcpdump, and so on because Windows tools were pretty bad for a while
    • Bypass various Windows restrictions on user’s systems
