  • One of my best friends lost her place of living when her boyfriend of 4 years said the relationship had actually ended in his head 2 years previously, but he needed the rent. But then he found a new girlfriend to grift from, “opened the relationship,” and they edged my friend out. I am still mad they did that to her; she was so heartbroken and damaged from that.



  • Cats can pant, I have seen it happen in times of extreme stress, and is often a bad sign. Like dogs, cats may pant if they are anxious or overheated. Strenuous exercise may be another reason, especially after a huge fight. Once your cat has had a chance to rest, calm down and cool down, this sort of painting should subside. However, even this type of panting is much more rarely seen in cats than in dogs. So, if you’re not 100% positive about why your cat is panting, it’s best to bring her to the vet.

    A side note, however, I misread this as “since cat’s don’t like pants like dogs,” and wanted to point out that dogs also do not like to wear pants, before my anti-dyslexia medicine kicked in.





  • I was burned afoul by a former admin who, instead of diagnosing why a mail service was failing, labeled a script as a /etc/cron.d file entry as “…” (three dots) which, unless you were careful, you’d never notice in an "ls " listing casually. The cron job ran a script with a similar name which he ran once every 5 minutes. It would launch the mail service, but simultaneous services were not allowed to run on the same box, so if it was running, nothing would happen, although this later explained hundreds of “[program] service is already running” errors in our logs. It was every 5 minutes because our solarwinds check would only notice if the service had been down for 5 minutes. The reason why the service was crashing was later fixed in a patch, but nobody knew about this little “helper” script for years.

    Until one day, we had a service failover from primary to backup. Normally, we had two mail servers servers behind a load balancer. It would serve only the IP that was reporting as up. Before, we manually disabled the other network port, but this time, that step was forgotten, so BOTH IPs were listening. We shut down the primary mail service, but after 5 minutes, it came back up. The mail software would sync all the mail from one server to the other (like primary to backup, or reversed, but one way only). With both up, the load balancer just sent traffic to a random one.

    So now, both IPs received and sent mail, along with web interface users could use. But now, with mail going to both, it created mass confusion, and the mailbox sync was copying from backup to primary. Mail would appear and disappear randomly, and if it disappeared, it was because backup was syncing to primary. It was slow, and the first people to notice were the scant IMAP customers over the next several days. Those customers were always complaining because they had old and cranky systems, and our weekend customer service just told them to wait until Monday. But then more and more POP3 customers started to notice, and after 5 days had passed, we figured out what had happened. And we only did Netbackups every week, so now thousands of legitimate emails were lost for good over 3000 customers. A lot of them were lawyers.

    Oof.



  • Worked a job where I had to be a Linux admin for a variety of VMs. To access them, I needed an VPN that only worked inside the company LAN, and blocked internet access. it was a 30 day trial license on day 700somthing, so it had a max 5 simultaneous connection limit. Access was from my heavily locked down laptop. Windows 7 with 5 minutes locking Screensaver. The ssh software was an unknown brand, “ssh.exe” which only allowed one connection at a time in a 80 x 24 console window with no ability to copy and paste. This went to a bastion host, an HPUx box on an old csh shell with no write access to your home directory due to a 1.4mb disk quota per user. Only one login per user, ten login max, and the bastion host was the only way to connect to the Linux VMs. Default 5 minute logout for inactivity. No ssh keys allowed. No scripting allowed, was like typing over 9600 baud.

    I quit that job. When asked why, I told them I was a Linux administrator and the job was not allowing me to administrate. I was told “a poor carpenter always blames his tools.” Yeah, fuck you.


  • Concussions. Especially when they are used as plot vehicles where someone is knocked out, and they wake up in a jail cell or whatever.

    If you got hit THAT hard on the head that you’re unconscious and unresponsive for hours? You are going to wake up dizzy, nauseated, and disoriented with a huge headache, loss of motor control, and a disorienting tinnitus. Possibly permanently. Your brain swelled up and cut off blood flow. You might look like a stroke victim. You will not wake up, rub your head, then pick a lock in a dark room and construct a bomb with a gum wrapper and a smoke detector battery. You will weep, vomit, and be unable to walk straight until you get real medical attention.

    Some action stars get knocked out almost every episode. I think MacGyver would have been mentally incapacitated after just a few shows.



  • A lot of outsourcers do this. Here’s my experience with a few companies.

    • The “team” you meet are competent, English speaking fronts. They are the demo models of the people who will work on your projects.
    • After the contract is signed, these people are swapped out with randos of varying competence.
    • In some cases, some of these randos are further hidden behind aliases: people with names that are actually more than one person sharing logins and passwords.
    • They will string you along, trying to charge maximum hours worked without regards to product or services delivered.
    • Most of these companies have a “bucket of crabs” mentality: the managers are horrible, the staff incompetent, and once the gain some skill, they leave for better companies. They backstab one another, hijack projects to fuck over coworkers, and lie and cover their tracks. Some of this is cultural, like a caste system, while some are just racist.

    At one time, these people were pretty good, but they realized they had skills and left for other countries for better pay and better working conditions. The bids got more and more competitive, cutting costs until they were literally filled with low-skilled labor who can’t be promoted or leave for economic or competence reasons.
