About trelliscoded

I do stuff with computers, networks, and security. I'm the laziest admin you'll meet. Clicking for hours in management interfaces is for suckers, I'd rather run a script. I'd rather all my coworkers run a script, too. Scripts for everyone!

I also do programming, especially embedded programming. Now it's called the "Internet of Things." Fortunately, the standards for security and reliability haven't changed that much relative to the history of embedded programming.

I am concerned that some customers are attaching things to the Internet of Things which should not be on the Internet of Things. Like cows. "Why can I not ping my cow?", one farm asks me. "Why did you put a cow on the Internet?!", I reply. They do not know, but Compliance says "because compliance," so now there's a cow on the Internet.

I am also concerned that NB-IoT is also going to be a thing in the near future. It's so cheap! It's so cheap, you can put cellular radios on all the things! Please do not do this. All the things do not need to run LTE stacks on energy harvesting SoCs forever and ever.

    I thought this was totally fascinating. Having a compact static object that can be used to cook without any other fuel inputs seems like a convenient thing to have around if you're…

    Yes. Firefox has its own password manager and profile system. Once I copied the chrome settings to firefox, I closed chrome and rarely open it these days.

    I’ve had to budget a line of business app that runs on both z/OS and AWS. Reliability for both hit an asymptote somewhere around 2019. The opex price crossover happened somewhere a…

    That’s interesting, I was looking at the ICE ERO statistics and not only do they show up as not having a published data source, only metadata, the corresponding dashboards at ice.g…

    The equal sign is a required character for anything base64 encoded, which includes some things you’d expect to be in a config file, like ssh public keys and x509 certs.

    The “CC” in the TI part numbers stands for “ChipCon”, who TI acquired for these wireless products. The CC1100, one of their earliest parts, has a documented but unsupported debug m…

    TI has had wifi+bluetooth microcontrollers for almost a decade now, and you get a cortex m4.

    That’s interesting, it’s like the difference between code used at runtime (protein coding DNA) and initialization code (lncRNAs). Both have to be there for the program to work, but…

    If your staging doesn’t do capacity checks in excess of what production sees, yes.

    OpenVMS and all its predecessors are still useful and, I think, ideal for real-time control applications and clustered high-reliability setups. The OS is structured much differentl…

    I use a Helium Mobile eSIM, which I pay with crypto. I set it up in something like 10 minutes when I became eligible for an account. No problems so far. I've also had eSIMs from Fi…

    Disabling script signing on dev machines and requiring signatures on production scripts sounds like perfectly reasonable behavior to me. I know a lot of people are scared of pki bu…

    It’s not an admin vulnerability, so there’s no hatchway. The real issue here is blindly passing user-provided input to a batch script, possibly from the Internet, and if you’re doi…

    The canals are just the edges of the entire path, the part in between is enormous compared to them. Because they flooded a forest, there’s a lot going on in the intermediate lake.
