  • As it got dark they began the arduous procedure of aiming the laser and something very quickly dawned on everyone: While considerable attention had been made in the design and alignment of the laser’s optics and in achieving good sensitivity of the optical receiver, no-one had really thought too seriously about the practical difficulties of aiming a very narrow beam over a distance of 118+ miles! Using a number of improvised techniques, the laser crew managed to get the beam “close”, setting the elevation with various shims and other pieces onhand, but getting both azimuth (horizontal) and elevation (vertical) dialed in proved to be a hair-pulling task.

    After a bit of fussing, the receive site crew was tantalized by the occasional brief, bright flash from the distant laser but it seemed as though the transmit site crew could never repeat the maneuver - plus the necessary corrections - to get the laser back and on-point! When the receive site crew queried the Grassy Hollow folks about this on the radio it turned out that they were using two primitive tools to adjust the aiming of the laser: A large rock tapped at the end of the metal channel in which the laser was mounted for coarse adjustments and a much smaller rock for fine-tuning!

    Having had to re-align a microwave radio link over a distance of about 30 miles, using a mount that was actually designed to make fine adjustments, I can only imagine how frustrating this was!



  • That’s fair, and I think a lot of the problems with that software was the internal developer/administrator for the software (I think it marketed itself as Open Source but was probably more accurately Source Available to customers) had taken it hostage with no one else allowed to touch it. I think it had become the proverbial million lines of undocumented spaghetti code that had guaranteed a permanent job for this guy because if he left the entire business would fall apart, including an inability to bring in revenue. Everyone knew he was a problem, except perhaps his boss, the CFO. When our companies merged they were originally supposed to join us on NetSuite (not without its problems of course but definitely better than the other software) but the hostage taker supposedly convinced the CFO that NetSuite wouldn’t be able to produce a report the CFO liked and we wound up moving to theirs instead. It was also supposed to save money by having lower user licensing costs. They brought in an outside consultant for our transition because the internal guy was too busy but then it turned out the internal guy was doing a bunch of non-standard stuff that didn’t work with the consultant’s design and the internal guy had to redo it anyways. When I left two and a half years later the company had spent millions on the transition and two different additional major pieces of software (the second replacing the first) trying to replicate what we’d had in NetSuite but was still lacking much of that functionality.


  • The advantage browser-based ones have is it’s generally easy to copy/paste any text you need. I used one that ran as its own desktop software and made many of the key text fields uneditable, instead of letting you copy text from them but refusing to save any changes to those fields that must not change. Want to grab the order number for this customer? Too bad! Type it yourself or export it to PDF and copy it from there! I was so happy when I discovered a little program that lets you copy any text on the screen by effectively taking a screenshot, running OCR on the screenshot, and putting the output onto your clipboard. Still took more effort than simply right-clicking the text and hitting copy, though, or double-clicking and hitting Ctrl-C.










  • The first Cybertrucks started shipping in November 2023 but most were more after the start of 2024, so at best it’s a 1½ year period.

    The article showed a screenshot of an owner who had tried Tesla’s online trade-in estimate with a 2024 that had only 6,211 miles on it.

    From the article:

    Tesla sold a brand-new 2024 Cybertruck AWD Foundation Series for $100,000. Now, with only 6,000 miles on the odometer, Tesla is offering $65,400 for it – 34.6% depreciation in just a year.

    Pickup trucks generally lose about 20% of their value after a year and 34% after about 3-4 years.

    It’s also wroth nothing that Tesla’s online “trade-in estimates” are often higher than the final offer as noted in the footnote o fhte [sic] screenshot above.

    On Car Guru, the Cybertruck’s depreciation is actually closer to 45% after a year and that’s more representative of the offers owners should expect from dealers.

    EDIT: corrected mileage from screenshot



  • If you’re okay with writing a little HTML and just don’t want to deal with writing/designing the CSS, I recently found out about HTML5 UP, which has a bunch of Creative Commons Attribution 3.0-licensed templates. It’s fairly straightforward to modify the content if you understand the HTML, and then you can host it for free as a static page at any number of places like GitHub Pages or Cloudflare Pages.

    If you don’t want to have the CC-By attribution on the webpage, the designer also offers a service called Pixelarity with the same templates and more for a $19/quarter non-renewing subscription. You can continue using the templates even after the subscription expires and can keep making new sites with any template you already downloaded, you just don’t get any updates or tech support when the subscription expires. Upload to one of those free static hosts and it’s dramatically cheaper than Ghost or WordPress, and probably less work than a static site generator for something that’s not changing often.
