I downloaded a preview portion of 390+ Python MCQs from Anazon, thinking reading through it would help me advance my Python skills beyond what I have learned from Harvard’s online CS50P (Python) course. I’m an experienced program looking to add a new skill to my repertoire, and while the course covered many significant aspects of Python programming, there are many other details to perfect, such as best practices, developing packages, and so on. The book is written by Manish Dnyandeo Salunke, who claims 15 years experience in IT, but it is not clear who published it. It is obvious no one edited it, or verified the correctness of the questions, answers and explanations. Amazon allowed me to download a sample of (I think) 57 questions. Roughly half of these were wrong, and some of the others struck me as irrelevant. The maximum allowed length for an identifier, apparently, is 79 characters. Anything over 20 characters should be considered unusual, so sufficient to say the limit is severa
I made a framing saw from a kit at a Lee Valley workshop, and it was fabulous. It's great as a coping saw, cutting curves, but the thin blade makes it hard to cut a straight line. So I made another one on my own, using a chunk of bandsaw blade, and this was better for straight cuts. But trying to resaw a 1" thick boards into two 1/2" inch boards was impossible. The cut would wander all over the place. I would practically wind up with veneer. I saw a number of articles and YouTube videos about making a re-sawing saw, and I decided to make one. But I'm not keen on kits. For one thing I'm stingy, and don't like giving away the profit. Besides, it doesn't feel like I made it, if someone else provided the challenging parts. So I made my own. The saw blade is cut from one of three rusty handsaw blades I got for $10 off Facebook Marketplace. I used an angle grinder to cut it out, a little over two inches wide, and to grind three-to-the-inch teeth
