The Nice American Eclipse v2.0 has come and gone, sadly with out our touring to the trail of totality as deliberate; household stuff. We did get a report from buddies in Texas that it was simply as spectacular there as anticipated, with the bonus of seeing a photo voltaic flare off the southwest limb of the disk at totality. Many individuals reported seeing the identical factor, which makes us a bit jealous — OK, rather a lot jealous. After all, this offered a chance to the “Effectively, ackchyually” crowd to level out that there have been no photo voltaic flares or coronal mass ejections on the time, so what individuals noticed wasn’t an exquisitely timed and well-positioned photo voltaic flare however slightly a well-timed and exquisitely positioned photo voltaic prominence. Glad we cleared that up. Both method, individuals within the path of totality noticed the Solar belching out gigatons of plasma whereas we needed to accept 27% totality.
The eclipse additionally offered loads of hacking alternatives for YouTubers in our neighborhood. Matthias Wandel went to nice lengths on brief discover to construct a photo voltaic tracker for photographing the eclipse, whereas Gabe Emerson from “saveitforparts” threw his little radiotelescope rig within the automobile and drove all the way down to totality to hearken to the Solar in the course of the eclipse. Jeff Geerling introduced three generations alongside for his eclipse celebration, which resulted in some great pictures and rubbing elbows with Destin from “Smarter Each Day.” Additionally fascinating is this evaluation of web visitors in the course of the eclipse by content material supply concern Cloudflare — or is that Cloudprominence? — which exhibits outstanding dips in web use throughout totality. The dips tracked throughout the continent from Mexico to Canada and lined up completely with the Moon’s shadow.
In non-eclipse information, somebody crunched the numbers on the forces concerned when the MV Dali rammed into the Francis Scott Key Bridge in Baltimore, and — wow! Making an allowance for the mass of the loaded container ship and its change in velocity in the course of the collision, the vessel imparted one thing like 26 million kilos of drive on the bridge. If our calculations are right, that’s over 115 million newtons, which, because the article notes, is equal to 66 totally loaded semi vans crashing into the bridge at freeway velocity . No marvel it collapsed prefer it was manufactured from toothpicks. Maybe probably the most fascinating factor we discovered from this text was that there’s an ordinary reference worth for the drive exerted on a bridge abutment by a truck crash, and it’s 400,000 kilos.
Git is a type of issues that’s so extremely helpful and so tightly built-in into our tradition that it’s laborious to recollect what we did for supply management earlier than it got here onto the scene. However supply management goes method, method again, maybe additional than you understand, as this collection of articles on supply management methods paperwork. This text is the primary of 4 components and focuses totally on SCCS and RCS. We had been stunned to study that supply administration solely grew to become a factor within the 70s when video terminals and magnetic mass storage grew to become extra ubiquitous. We’re wanting ahead to the second half, which covers the unhealthy previous days of CVS, SourceSafe, and ClearCase, which is the place we first fell down the supply management rabbit gap.
And eventually, we wished to share this fascinating video on the unlikely origins of the primary desktop pc: the steering pc of the Minuteman I ICBM. In 1962, computer systems stuffed total rooms, however the Autonetics D-17B got here in at a mere 28 kilos, a outstanding accomplishment in pc miniaturization. About 800 of the general-purpose digital computer systems had been fielded, and when the Minuteman I gave solution to different, extra succesful ICBMs, the decommissioned computer systems had been distributed freed from cost to universities and different establishments. The chief impediment to placing certainly one of these machines to work appears to have been developing with an influence provide, however as soon as that was completed, a “Minuteman Laptop Customers Group” stood prepared that can assist you get going.
