  • "Reflecting on my own workflows with a chopsaw, primarily rough cutting raw lumber from a cutlist for further processing, this thing does make sense. I completely agree that little beats a good stop block setup for repeated cuts. But for cutlists, which the video specifically calls out, this design destroys tape measures.  That’s either a handheld tape measure, which is a hassle, or an adhesive tape mounted to a miter station.  Either way, the user has to fuss with the tape and/or  joggle back and forth along the workpiece, trying to eyeball the correct cut length badly. With this device, you just zero it and proceed to work down your cutlist as the workpiece is consumed."

  • "Speaking from experience, I tend to simply curse anything other than properly designed range hoods for the primary task of removing particulates and fumes from cooking.  In short, it’s effectively impossible for cooktop or pop-up extractors to do a good job “because physics”.  In this regard, cooktop extractor fans have a similar challenge as industrial dust collection systems.  The intuition, however, is easy.  Think about blowing vs. sucking air through a straw.  It’s easy to blow through a straw and feel the stream of air at quite a distance away, as you’ve created a directed stream of air.  But think how close do your hand needs to be to the end of the straw to feel air being sucked in. In the suction case, air is being pulled evenly in a (hemi-)spherical space.  This is why the hood on a range hood extractor is important: as collection space for the hot, rising gases so the extractor fan “has time” to capture and remove them.  Without a properly designed above-mounted range hood, it’s inevitable that a huge amount of the cooking fumes simply escape upward and away.  Most recently, my experience with a nominally well-regarded pop-up extractor was that it was just a “slingshot” for greasy cooking fumes into the adjacent space. I think there’s a strong argument that this entire category of extractor is a particularly bad kind of “form over function”."

  • "The software development community is having an analogous conversation right now.  The by-far dominant version control software, git, has long named the default code branch ‘master’.  One of the best alternative suggestions I’ve seen so far is simply ‘main’, which I think works well here as “Main Bedroom”.  It’s unambiguous, doesn’t conflate architectural features such as an “en suite” bathroom with the role of the bedroom (not all such bedrooms have an en-suite bath).  “Owner’s Bedroom” in the example floor plan is a terrible choice, as it names the /role of the space/ for /who owns the property/ which is outright wrong for anyone who rents and probably other cases. For many people, that creates the connotation of staying in someone else’s space, which is certainly not how people want to think about “home”."

  • "This is super interesting, just from consumer-scale additive manufacturing. But it further opens doors to innovative new components like the Pinion gearbox (https://pinion.eu/en/). Pinon requires specific support in the frame which means it’s mostly offered by custom frame builders, greatly increasing the overall cost. For Superstrata, this “cost” would be a one-off addition to their master configurable CAD model."
