  • Creating a HEAD utility for Windows 10

    One of the things I did often in my first career job was create utilities that we could use as a network support team. I was an intern coming from university, where I used SunOS and Solaris all the time. I was used to a command line for a lot of work. While DOS worked well, there were things I missed, like whoami, head, tail, etc.

    I rebuilt a bunch of those as DOS batch files for myself, but I expanded this to more useful things. We supported over 1000 people, and finding their phone extensions was a pain, especially in the early 1990s with phones that had cords and pagers. We had a common file share that contained a text phone directory, so I built 411.bat, which took a parameter and searched that file for a matching name. Then returned the line of data. It was immensely helpful to us.

    The other day I had a large file that I wanted a glimpse of. I opened it in Notepad++ (this was GBs of data), but it took time. That made me think I’d really like HEAD on Windows. I tried it, but it’s not there.

    So I built it. This is my command file:

    powershell “get-content %1 | select-object -first 10”

    I save this in a utilities folder in my path. Then in other folders, I can run it and get a glimpse of text files I’m importing or working with. Way, way faster than Excel or trying to open this in another program. I often have a cmd open, so this is useful to me. You can see it working below.

  • Daily Coping 15 Aug 2022

    I started to add a daily coping tip to the SQLServerCentral newsletter and to the Community Circle, which is helping me deal with the issues in the world. I’m adding my responses for each day here. All my coping tips are under this tag.

    Today’s tip is to make some tasty food for someone who will appreciate it.

    My daughter left for college last week. A few days before she left, I asked her what she might like for dinner. She is gluten sensitive, so while I can cook a lot of things, I often need to modify or prepare things for her.

    She asked for a few things, which I enjoy cooking and the rest of the family enjoys. We did a tasty Greek dinner:

    I also made pineapple sorbet, which everyone enjoyed.

  • Initial FSD Thoughts with a Tesla Subscription

    This is part of a series that covers my experience with a Tesla Model Y.

    I subscribed to the Tesla FSD in July, since I had a couple trips planned where I’d be driving longer distances on the highways. I wanted to see how well it worked and what value there was from the subscription.

    Cost-wise, this is a good way to try things out. The FSD cost is US$12,000. If I subscribe, it is US$199. Worth a month to test this out and see what it gets me. The additional items for FSD (and Enhanced Autopilot) are:

    • Navigate on autopilot
    • Auto lane change
    • Auto park
    • Summon
    • Smart Summon
    • Traffic Control and Stop Sign Control

    Note: This isn’t the beta version of FSD that everyone is writing about. This is production, which is less capable. I could have opted into the beta, but decided not to.

    Subscription was easy. I clicked a few buttons on the app and within minutes, I had new options in my Autopilot screen. I clicked on a few and set up some confirmations and enabled options.

    I then tried it on some shorter trips. Overall, I appreciated the ability for the car to stop at stop lights and stop signs, though the confirmation from me wasn’t great. However, I don’t completely trust the car, so I liked it.

    I also did like the lane change on the highway. Often when I’ve used Autosteer, I get behind a slow person at some point and I’d like to be able to change lanes. It did work well when I confirmed a lane change and waited for other cars that were close to pass (or fall back) before the car moved lanes. I could not initiate these changes, however. I had to wait for the car to ask if it could change lanes.

    There still is some phantom breaking and some weird speed changes at times, so it’s not anywhere close to perfect, but I liked the feature.

    I don’t think this is worth US$200 a month for these features, but maybe at $100 I’d use it I drove more. I just don’t go on enough longer rides to use this very often.

    I’ll write a few posts and shoot video of a couple of the features.

  • Daily Coping 12 Aug 2022

    I started to add a daily coping tip to the SQLServerCentral newsletter and to the Community Circle, which is helping me deal with the issues in the world. I’m adding my responses for each day here. All my coping tips are under this tag.

    Today’s tip is to smile and be friendly to the people you see today.

    Another trip today. Back last night from Seattle and off to LA today. I try to do this in general, but making a note to emphasize this today, no matter how tired or stressed I might feel.
