We get started this 7 days with news from Mars, due to the fact, let us facial area it, the information from this planet is not all that substantially fun lately. But a pair of milestones ended up achieved on the Red Earth, the 1st being the arrival of Perseverance at the ancient river delta it was sent there to examine. The rover unquestionably took the scenic route to get there, acquiring lined 10.6 km more than the past 424 sols to transfer to a placement only about 3.5 km straight-line distance from the place it landed. Granted, a whole lot of that added driving was in support of the unexpectedly thriving Ingenuity demonstration, in addition using time for a ton of pit stops alongside the way at appealing features. But the rover is now in area to study sedimentary rocks most probably to harbor the fossil continues to be of historic aquatic lifestyle — as opposed to the mainly igneous rocks it has analyzed together the crater ground so far. We’re wanting ahead to viewing what takes place.

Speaking of Ingenuity, the plucky helicopter just retains on carrying out. It a short while ago done its 27th flight — of five planned flights, brain you — and spotted the crashed remains of the aeroshell and parachute from its magnificent arrival previous February. They glimpse pretty the worse for the dress in, but that is to be predicted. The stunningly high-resolution photographs Ingenuity sent back will no doubt be pored more than by engineers for regardless of what clues it holds about how the framework stood up to descent and landing circumstances. We’re not confident, but this may be the first time a landing or crash site has been revisited since Allan Bean unquestionably nailed the Apollo 12 landing to inside going for walks distance of Surveyor 3 in 1969.

“And the Emmy goes to… Comedian Sans?” No, not truly, and apologies to any one activated by the mention of The Font That Shall Not Be Utilised. But this 7 days the 2021 Know-how & Engineering Emmy award went to the Globe Large World wide web Consortium (W3C) World wide web fonts Operating Team and MPEG alongside one another for “standardizing font technologies for custom downloadable fonts and typography for world wide web and Tv set devices.” To be distinct, the award is not for any unique font, but somewhat the technical achievement of downloadable fonts. Nonetheless, it’s simple to poke pleasurable at typography, specifically when font snobs go on about the deserves of this serif or that descender. But all those subtle differences that most of us think are meaningless really perform a massive job in the “feel” of sites. Website fonts have a whole lot to do with how polished and experienced most web pages seem these times, in comparison to some of the atrocities of the Net 1. times.

A pair of months again, we experienced a PCB Thermal Design and style Hack Chat in excess of on Hackaday.io with Mike Jouppi. It was a wonderful dialogue and spawned an intriguing sidebar with attendee Sven about thermal vias. It looks like Sven’s software had a great deal for Mike to sink his enamel into, for the reason that he produced an in-depth video on the thermal structure of this PCB, together with a discussion of what went into developing IPC-2152, the normal for PCB trace present-day-carrying potential structure. Thanks to Mark Hughes of Superior Assembly for the heads up on this, and for suggesting Mike occur on the Hack Chat in the to start with put.


And last but not least, it appears to be like like Lichtenberg designs are acquiring popular more than enough that it is important to warn people that enjoying with electrical energy can be dangerous. Lichtenberg patterns, which are fractal channels burned into wooden or other components by the (hopefully) even handed software of large voltage, are surely some thing we have viewed and highlighted prior to. Nevertheless, the American Affiliation of Woodturners — for the reason that of system there is these a team — now condemns the practice, which seemingly has caught on in the woodturning neighborhood. The AAW really does not want everyone carrying out Lichtenbergs — they banned the apply at all their events and in their publications, enlisted the assist of a physician to convey to all people that energy can end your heart, and urged anyone who has fractal woodburning gear to throw it out now right before it attacks. We fully grasp and wholeheartedly agree that doing the job with substantial voltage can be dangerous, and we’re not expressing that woodturners must not take the most likely lethal repercussions of Lichtenbergs very seriously. But this warning looks a little bit prosperous coming from an business that encourages its customers to stand in front of a equipment that can throw razor-sharp tools at you, fling major chunks of wood at your head, or instantaneously reduce you of your garments — or worse. Be safe out there, absolutely everyone.
