  • You could say the same for a finite element model. A junior engineer with just 4 years of training can solve, explicitly, the deflection at the center of a slender, simple-simple beam of prismatic section and produce an exact (if slightly incorrect) answer. Building a FEM of the same can solve the problem and take longer (to make the model) with similar accuracy, both of which are good enough for design work.

    Only a fool wouldn’t have a FEM around though, as it can solve problem that would take centuries for a human to solve. They may as well make a cartoon with the child digging a 3” hole in beach sand and then showing a backhoe making a jagged edged hole of the same size.

    I have own a rift and Q1, 2, and 3 (plus some older, but polished, Cardboard products) but have NOT had a VP demo. The jump from fresnel to pancake lenses - for productivity purposes - is substantial and I expect the VP’s moderately higher resolution to be enough to make the headset actually productive (Q3 is close but still resolution handicapped). I expect the tight integration with OSX to be useful and, if I were (a) on OSX (b) didn’t already work on an 8K monitor and © was a digital nomad or had no dedicated office/room in which to work, I could see a use case for them. Having attempted to work in i(Pad)OS professionally as a remote platform, the standalone capabilities might be useful for a blogger or journalist but is utterly unsuitable for professional work, even less so without a dedicated keyboard and mouse/advanced multitouch track pad. Again, I’ve not used the VP hand-sensing for advance selection* but my expectation is that it is still in its infancy, even with (and perhaos hindered by) eye focus selection.

    My hope is that $3500/pop will allow more research, more fine tuning, and advancing to vision limited resolution (Apple is still a factor of 4 short in pixel count, and a factor of 6+ short of my desktop monitor) for future headsets.

    * multi-functional, 3D manipulation of, say, finite element model components or full building/industrial models in a program like Revit or multi-assembly models in Blender or Fusion360, where you have 4+ key modifiers plus 3 buttons and two scroll wheels for fine manipulation and hundreds of quick-key commands)






  • Well, that and every time you touch a DOC/DOCX file it reformats itself to your local settings, fucking up the entire layout. PDF is a terrible, inefficient, poorly (or at least variably) implemented format which was proprietary for two decades but is now about the best option we have for a document to look the same at the recipient end as the sender and still include text, vector, bitmapped, semi-interactive, and certifiable/traceable contents.





  • Reminder - gas prices cannot be hiked by suppliers because they don’t own the gas. Petroleum products are bought and sold on commodity markets before they’re ever refined or even removed from the ground. These “futures” are bought and sold and the price at the pump is related to the current price to purchase the product from the commodity brokers, plus transportation and local markup.

    There are legitimate uses for futures contracts, but much of it is just gambling and capitalistic opportunism.









  • That’s sort of how I do mine. I put all my data onto dropbox/onedrive. I’ve got a $100 HP USFF hooked up in my office that is a 100% online mirror for those cloud accounts, and it backs up to an 8TB external each week. I rotate that drive with a spare each month (give or take), putting the “offline” one in a firesafe. It means I have a live copy (my pc), a cloud copy (OD/DB), a second hot copy (USFF PC), a near-line backup no more than 7 days old that isn’t “live” and a cold storage copy that is no more than a month old (aka less than Apple’s deleted-pictures and Dropbox’s previous version storage time). It cost me two external drives and the mini-pc. And if all those fail I’ll probably be roaming the radioactive wasteland looking for food and losing that data won’t matter.

    Oh, and that little box also runs a small FTP server and my Torrents for my Linux distro collection.
