  • What Australia exports is likely Low-Enriched Uranium (LEU), which is less than 20% U²³⁵, and is suitable for nuclear power plants.

    Nuclear powered submarines require Highly Enriched Uranium (HEU), which is 20% or more U²³⁵.

    Weapons-grade uranium is usually enriched to 90% or higher.

    Getting to that 90% level is extremely difficult & time consuming. U²³⁵ and U²³⁸ are chemically identical, so it’s converted to a gas & spun in centrifuges to separate the atoms by weight. Typically hundreds of centrifuges are used in this process. As an example, it took roughly 3 years for the Manhattan Project to refine enough U²³⁵ for the first bomb. That bomb used roughly 60 kilograms of bomb-grade uranium. To get those 60 kg, over 9 metric tons of raw uranium was processed.

    It’s this weapons grade uranium that Iran has collected and is protecting.


  • Hell, there are nation states that have been doing this sort of thing for decades. 15 or so years ago I worked in IT at a university. They bought some servers from IBM and had IBM install them on public IP addresses. It is extremely well known that IBM regularly uses default passwords (or at least used to) like “PASSW0RD” with a zero for the O. I had access to one of these servers about 15 minutes after it was set up, and the first thing I did after changing the password was to check the logs. Sure enough an IP address from China had already logged in as root. I immediately wiped the entire server clean and reinstalled everything.












  • Born in 1967. I remember as a kid during the summer that pretty much every afternoon 10-20 neighborhood kids would get together to play games like hide and seek or kick the can. We were in a semi-rural neighborhood so kids could live up to a mile away or so. The parents were more than happy for us to be somewhere random with a bunch of other kids.

    When parents had to call kids home for dinner they’d use bells, whistles, or other noisemakers. Pretty much every kid recognized the different sounds and knew which kids it applied to.

    My grandparents lived in New Hampshire. Their telephone was on a party line shared with 4 or 5 neighbors. We learned to answer it only if it rang twice in quick succession.






  • Juries often have one or more alternates. Those are jurors who sit in the jury box for the entire trial, but under normal conditions they aren’t in the jury room during deliberations. If a juror is unable to remain, for whatever reason, then the judge replaces that juror with one of the alternates. I sat on 2 days of a 3 day trial but tested positive for Covid the morning of the third, so I was excused. The judge replaced me with one of her alternates.

    If the judge got wind that a juror was disregarding such an order then that juror would likely be kicked out & replaced with an alternate. If the transgression by the juror was severe enough the judge could potentially also refer the juror to the Attorney Generals office for investigation and possible charges.


  • I’m a DevOps engineer (about 15 years) and in a previous life was a software engineer (15 years before that). My employer is pushing hard on AI so I reluctantly started using Claude at times. I must say that I’m fairly impressed when it comes to relatively easy tasks. We’re a large AWS user and have developed a fairly complex in-house set of python tools that encapsulate things like Terraform and Ansible. We have about 15 or so AWS sub-accounts that span logical groupings, so our IAM configuration alone was fairly complex.

    I was able to point Claude at our IAM configuration and tell it to create a set of policies/roles to allow a host in one environment to access resources in a read-only manner across all our accounts. Since I’m not an IAM expert it would have taken me a few hours to figure out what it did in under 10 minutes. Two of my team reviewed the proposed changes and were perfectly fine with them.

    I’ve also had it write python scripts that do things like call AWS APIs, collect JSON results, and compare it to contents pulled from a git repo of configuration data.

    For relatively simple tasks like these it can be a time saver. But you still need to sanity check everything it does. I’ve seen it skip steps (like not applying IAM policies to all our accounts), and when you point it out it will apologize and fix things. But it’s that sort of failure that makes me still be wary of AI. Like why only update a subset of things and fix it only after I point it out? “All” means “all”, not “some”…

    For more complex things I’m still very reluctant to trust it. When it comes to that I may use Claude to encapsulate a few API calls, but then I’ll rely on my own expertise to add in all the really important logic.
