  • I’m not sure about what the article is referencing, which is probably a little more exotic, but relay attacks are very common against keyless cars. Keyless cars are constantly pinging for their matching fob. A relay attack just involves a repeater antenna held outside the car that repeats the signal between the car and the fob inside the house. Since many people leave the fob near the front of the house, it works and allows thieves to enter and start the car. Canada has has a big problem with car thieves using relay attacks to then drive cars into shipping containers and then sell them overseas.




  • Years and years ago I built my own 16 bit computer from the nand gates up. ALU, etc, all built from scratch. Wrote the assembler, then wrote a compiler for a lightweight object oriented language. Built the OS, network stack, etc. At the end of the day I had a really neat, absolutely useless computer. The knowledge was what I wanted, not a usable computer.

    Building something actually useful, and modern takes so much more work. I could never even make a dent in the hour, max, I have a day outside of work and family. Plus, I worked in technology for 25 years, ended as director of engineering before fully leaving tech behind and taking a leadership position.

    I’ve done so much tech work. I’m ready to spend my down time in nature, and watching birds, and skiing.


  • The article says that steam showing a notice on snap installs that it isn’t an official package and to report errors to snap would be extreme. But that seems pretty reasonable to me, especially since the small package doesn’t include that in its own description. Is there any reason why that would be considered extreme, in the face of higher than normal error rates with the package, and lack of appropriate package description?



  • While not related from a legal standpoint, the use of iPhones and intermediate devices reminds me of a supreme Court case that I wrote a brief about. The crux of it was a steaming service that operated large arrays of micro antenna to pick up over the air content and offer it as streaming services to customers. They uniquely associated individual customers with streams from individual antenna so they could argue that they were not copying the material but merely transmitting it.

    I forget the details, but ultimately I believe they lost. It was an interesting case.


  • I use a terminal whenever I’m doing work that I want to automate, is the only way to do something such as certain parameters being cli only, or when using a GUI would require additional software I don’t otherwise want.

    I play games and generally do rec time in a GUI, but I do all my git and docker work from the cli.







  • So you just asked the most confusing thing about AWS service names due to how names changed over time.

    Before S3 had an archival tier, there existed a separate service that AWS named AWS Glacier Storage, and then renamed to AWS S3 Glacier.

    Around 2012 AWS started adding tiers to S3 which made the standalone service redundant. I received you look at S3 proper unless you have something like a Synology that can directly integrate with the older job based API used by the original glacier service.

    So, let’s say I have a 1TB archival file, single tarball, and I upload it to a brand new S3 bucket, without version, special features, etc, except it has a life cycle policy to move objects from S3 standard to S3 Glacier instant access after 0 days. So effectively, I upload the file and it moves to Glacier class storage.

    The S3 standard is ~$24/tb/month, and lets say worst case scenario our data sits on standard for one whole day before moving.

    $0.77+$0.005 (API cost of the put)

    Then there is the lifecycle charge to move the data from standard to glacier, with one request per object each way. Since we only have one object the cost is

    $0.004 out of standard
    $0.02 into glacier

    The cost of glacier instant tier is $4.1/tb/month. Since we would be there all but one day, the cost on the first bill would be:

    $3.95

    The second month onwards you would pay just the $4.1/month unless you are constantly adding or removing.

    Let’s say six months later you download your 1tb archive file. That would incur a cost of up to $30.

    Now I know that seems complicated and expensive. It is, because it is providing services to me in my former role as director of engineering, with complex needs and budgets to pay for stuff. It doesn’t make sense as a large-scale backup of personal data, unless you also want to leverage other AWS services, or you are truly just dumping the data away and will likely never need to retrieve it.

    S3 is great for complying with HIPAA, feeding data into a cdn, and generally dumping data around in performant way. I’ve literally dropped a petabyte off data into S3 and it just took it and did its thing.

    In my personal AWS account I use S3 as a place to dump cache contents built by lambda functions and served up by API gateway. Doing stuff like that is super cheap. I also use private git repos (code commit), private container registry (ecr), and container host (ECS), and it is nice have all of that stuff just click together.

    For backing up my personal computer, I use iDrive personal and OneDrive, where I don’t have to worry about the cost per object, etc. iDrive (not an Apple service) let’s you backup multiple devices to their platform and keeps them versioned.

    Anyway, happy to help answer questions. Have a great day.


  • Just because they don’t issue a bill doesn’t mean they don’t track costs. They track labor, labor rates, and consumables.

    That said, this particular treatment is very involved. They harvest cells over multiple periods, send them to a lab to be modified, and when they are ready they do chemotherapy to kill your immune system, then do a bone marrow transplant to introduce the modified cells, and then you have to be in isolation in a hospital until your immune system comes back. Even the best facilities are saying they can only do 5-10 of these per year.

    Pretty crazy.
