What’s next for Windows and Surface without Panos Panay?

Posted on by Michael G
The Verge: Panos Panay has always been the force behind Microsoft’s Surface line. He helped bring Surface to life as a secret project more than 10 years ago. He’s presented the new devices onstage at events, showed up at malls to promote Surface hardware, and has steered Microsoft’s Surface tablets to success in the years since. Now, he’s leaving in a surprise departure announced just days before Microsoft’s next big Surface event. Panay will no longer be presenting at Microsoft’s showcase on Thursday but will remain at the company for another couple of weeks as part of a transition process. He’s reportedly joining Amazon to replace Dave Limp and lead Amazon’s Echo and Alexa push. Amazon is also holding its own hardware event on Wednesday. This sure is an odd and rather abrupt departure – only a few days before Panay was supposed to be present Microsoft’s Surface event – and I wonder what the full story is, and if we’ll ever get to hear it. I have mixed feelings about Panay’s tenure at Microsoft. As far as hardware goes, Surface devices are quite nice and pleasant, albeit often a tad bit out of date for the prices Microsoft is asking. Worse yet, Microsoft and Panay, despite halfhearted attempts, completely missed the boat on ARM, and Windows is still floundering there due to both poor ARM hardware (compared to Apple’s offerings) and Windows on ARM being an afterthought. As far as software goes – well, Windows is in a worse state than it’s ever been in. It’s the clown car of operating systems, and two decades of layering one user interface and API above another has turned the operating system into a layer cake that makes Hisarlik seem like a thin sheet of single-ply toilet paper. The ways in which Microsoft has jerked Windows from left to right are numerous, and Panay was at the head of it all for a long time. Maybe Microsoft’s relentless push for shoving AI down Windows’ users’ throats as the straw that broke Panay’s back?

Primitive Technology- Bow and Arrow

Posted on by Michael G
I made this bow and arrow using only primitive tools and materials.The bow is 1.25 m (55 inches) long and shoots 60 cm (2 feet) long arrows. I don’t know the draw weight – safe to say greater than 15 kg (35 pounds) perhaps? The stave was made from a tree ,Northern Olive (Chionanthus ramiflora), that was cut with a stone axe and split in half with a stone chisel. One half was used for the bow and was cut to a length of 1.25 m (50 inches). The limbs of the bow were carved with various stone blades so that the limbs tapered in width, and to a lesser extent depth, towards the tips. The middle of the bow was narrowed in width to form a handle about 12.5 cm (5 inches) long.
The string was made from the inner bark of a fibrous tree. It was separated into thin strips and left to dry. Then it was twisted into cordage.
Arrows were made of the same wood as the bow and were 60 cm (2 feet) long. A notch was carved into the back to accept the bow string. They were fletched with bush turkey feathers picked up from the ground (no turkeys were harmed in the making of this video). A feather was split in half and cut into 3 lengths then resin and bark fiber attached the fletching on to the arrows. The tip of the arrow was fire hardened and sharpened to a point. The fletching was trimmed using a hot coal. Each arrow took about an hour to make. A quiver was made of bark to hold the arrows. Importantly, the quiver was worn on the back in the historically accurate style of native American and African archers- not on the hip like medieval European archers (see back quiver: https://en.wikipedia.org/wiki/Quiver ).
I cleared a shooting range with a semi rotten log as a target instead of a hay bale. At 10 meters the accuracy was better than 50 % for this narrow target and the arrows stuck into the wood enough so that they were difficult to pull out. The bow was durable, shooting about 200-300 times with the string breaking only 3 times. I made a back up string and repaired them by splicing the ends back together.
In conclusion this was an easy bow to make. The short design makes it easy to find a straight piece of wood for the stave. A short string is also easy to make and short arrow shafts are easy to find. Short bows shoot fast and are easy to carry in thick forest. The dimensions of the bow were based on those given in the SAS Survival Handbook by john Lofty Wiseman. but instead of carving it from a stave from the start, I split the stave and then carved it. I think this requires less time, effort and skill. It also gives a flat bow design that’s unlikely to break. It does require wood that doesn’t twist much when split though.

Introduction to immutable Linux systems

Posted on by Michael G
If you reach this page, you may be interested into this new category of Linux distributions labeled “immutable”. In this category, one can find by age (oldest → youngest) NixOS, Guix, Endless OS, Fedora Silverblue, OpenSUSE MicroOS, Vanilla OS and many new to come. I will give examples of immutability implementation, then detail my thoughts about immutability, and why I think this naming can be misleading. I spent a few months running all of those distributions on my main computers (NAS, Gaming, laptop, workstation) to be able to write this text. I haven’t given any of these a try just yet, but I feel like this is where the Linux desktop is going. I’m not sure if that’s a good or a bad thing – I need both more experience as well as read more informed opinions about it – but I do like the concept.
