  • The problem is computer vision has a LONG way to go before it’s truly on par with human eyesight. Musk loves to crow how cameras are sufficient since we use our eyes to drive.

    The thing is, eyes have special neural circuits that detect motion. They essentially filter out unnecessary information and send just the motion details to the brain. This prevents the brain from being overloaded with every detail the eye constantly sees.

    And being overloaded with everything is exactly what computer vision currently does. It’s just a stream of images that the computer must analyze completely. So it’s working exactly opposite to how the eye & brain works.







  • ANI and CallerID serve two very different purposes. Suppose you managed the telephones for something like an insurance company, where you have lots of customers calling in, but also have lots of employees calling out. You want the Caller ID on your customers phones to show the main # for your company whenever you call them, so it would show something like 1-212-555-1000.

    Because the company has a lot of employees, it has 100 individual phone lines, so 100 agents can be on calls at the same time. The phone company actually allocates 100 numbers in that case, and those numbers could be very different than the above -1000 number. So the numbers 1-212-555-7000 through 1-212-555-7099 all belong to the company. Each time an employee makes a call their telephone system finds any one of those numbers between -7000 and -7099 that isnt in use and uses it. The call is billed to that specific number, and the bills for all 100 lines are combined & billed to the company at the end of the month.

    If the company couldn’t configure its phones to display 1-212-555-1000 as the Caller ID then customers would see random numbers in the range of -7000 to -7099 any time the company called them.




  • Play paintball.

    I started playing back in the 80’s when I was in college and everybody used paint guns that could only hold about 15 rounds, and fired one at a time.

    I’m way too old to run around in the woods like I did 40 years ago, and the game has completely changed as well. People have guns that can hold hundreds of paintballs and shoot incredibly fast, so the whole strategy is unlike it was. I just don’t find modern paintball enjoyable at all.





  • If you mailed in a ballot then there should be a way to confirm it was received, but there should NOT be a way to see who you voted for. Just like they can confirm that you voted in person, but again can not tell who you voted for when you showed up to vote.

    Typically when you vote by mail you receive a ballot plus two envelopes. You fill out the ballot and put it in the inner envelope that should contain no markings as to whose ballot it belongs to. This is put inside the second envelope that should have your contact information (my state uses a barcode for this) and that you have to sign.

    When the city/town clerk receives the ballot they look up your voter registration & confirm the signature on file matches the signature on the envelope. They then check off in their records that you voted by mail on that day. They take the inner envelope out of the outer envelope and add it to the other pile of envelopes they’ve received. At some later point they open those envelopes and count the ballots, but have no way of associating a given ballot back with the person who mailed it in.

    If you then try to go vote in person on Election Day (or somebody tries to impersonate you) then their records will show you already voted and you won’t be allowed to vote again.





  • I recall when I bought my first hybrid that the dealer said there were something like 15 different computers controlling things, from the ICE engine to the transmission to the charging of the battery, etc. They weren’t networked together.

    I also once ran afoul of a software bug in the ECU of a Honda CR/V. That’s the embedded system that manages the whole operation of the engine - from fuel injection to timing to emissions etc. As they progress through model years they use different ECUs that require different software. Even though I work in IT, I wouldn’t feel comfortable trying to update it myself, given the different models, firmware revisions, etc. I was more than happy to take that car to a dealer to have them confirm my car had buggy software and to upgrade it to the right new version.
