How To Build With Delrin and a Laser Cutter 25

szczys writes: Laser cutters are awesome, but you have to bring your mechanical engineering A-game if you want to build resilient stuff using laser-cut parts. Joshua Vasquez has been building up his bag of tricks using Delrin and a laser cutter to build with techniques like press-fitting, threading, snap-fits, etc. that aren't possible or are non-ideal with the laser-cutting steadfasts of plywood and acrylic. Delrin (PDF) won't shatter like acrylic, and it has more give to it, so even the less precise entry-level lasers can cut joints that will have a snug fit.

That does not mean you will ever be any good at it or master more "advanced" things like addition. Really, "coding" is not putting basic building blocks together in obvious ways, because that is something any halfway smart and educated person can do.

Also, WTF has writing HTML to do with coding? Are we now so cretinized that people do not even have a basic understanding of what coding means?


You Don't Have To Be Good At Math To Learn To Code 601 writes: Olga Khazan writes in The Atlantic that learning to program involves a lot of Googling, logic, and trial-and-error—but almost nothing beyond fourth-grade arithmetic. Victoria Fine explains how she taught herself how to code despite hating math. Her secret? Lots and lots of Googling. "Like any good Google query, a successful answer depended on asking the right question. "How do I make a website red" was not nearly as successful a question as "CSS color values HEX red" combined with "CSS background color." I spent a lot of time learning to Google like a pro. I carefully learned the vocabulary of HTML so I knew what I was talking about when I asked the Internet for answers." According to Khazan while it's true that some types of code look a little like equations, you don't really have to solve them, just know where they go and what they do. "In most cases you can see that the hard maths (the physical and geometry) is either done by a computer or has been done by someone else. While the calculations do happen and are essential to the successful running of the program, the programmer does not need to know how they are done." Khazan says that in order to figure out what your program should say, you're going to need some basic logic skills and you'll need to be skilled at copying and pasting things from online repositories and tweaking them slightly. "But humanities majors, fresh off writing reams of term papers, are probably more talented at that than math majors are."

I disagree. Most of the opposition to systemd is completely factual and based on technical arguments. There are a few loud-mouths, sure, but the actual majority of people using invalid emotional arguments, direct insults and "hate" are the systemd proponents. It is really quite fascinating to see how these people do not "mesh" at all with Unix culture, but rather seem to be a hostile invading force. There are rather strong suspicions that many of these people are paid-for PR shills, and not actual users. Their script is just too similar every time they start to put everybody down that does not profess love to systemd. And they almost universally go for the emotional approach, which means they do not have any strong tech arguments.

Very likely. And "creepy" is not the right word. Having files on everybody and laws that allow you to get everybody (and the US certainly has both) is necessary to establish and firm up a police-state and eventually full fascism.

As the average US citizen just does not seem to care, I guess it is time for the US to get its own hands-on taste of national fascism. Unfortunately, the rest of the world will not be able to bust them out, so it will be of the slow-decline form that takes a century or so to total economic collapse and the survivors will have to build up again from ruins.


Windows 10 Grabs 5.21% Market Share, Passing Windows Vista and Windows 8 244

An anonymous reader writes: The effects of a free upgrade to Windows 10 are starting to trickle in. Available for just over a month, Windows 10 has now captured more than 5 percent market share, according to the latest figures from Net Applications. In just four weeks, Windows 10 has already been installed on over 75 million PCs. Microsoft is aiming to have 1 billion devices running Windows 10 "in two to three years," though that includes not just PCs, but smartphones, consoles, and other devices as well.

Carbon Dating Shows Koran May Predate Muhammad 616 writes: Brian Booker writes at Digital Journal that carbon dating suggests the Koran, or at least portions of it, may actually be older than the prophet Muhammad himself, a finding that if confirmed could rewrite early Islamic history and shed doubt on the "heavenly" origins of the holy text. Scholars believe that a copy of the Koran held by the Birmingham Library was actually written sometime between 568 AD and 645, while the Prophet Mohammad was believed to have been born in 570 AD and to have died in 632 AD. It should be noted, however, that the dating was only conducted on the parchment, rather than the ink, so it is possible that the Koran was simply written on old paper. Some scholars believe, however, that Muhammad did not receive the Koran from heaven, as he claimed during his lifetime, but instead collected texts and scripts that fit his political agenda. "This gives more ground to what have been peripheral views of the Koran's genesis, like that Muhammad and his early followers used a text that was already in existence and shaped it to fit their own political and theological agenda, rather than Muhammad receiving a revelation from heaven," says Keith Small, from the University of Oxford's Bodleian Library. "'It destabilises, to put it mildly, the idea that we can know anything with certainty about how the Koran emerged," says Historian Tom Holland. "and that in turn has implications for the history of Muhammad and the Companions." Update: 09/01 17:32 GMT by S : There was a typo in the dates used by the original linked article — in the press release from the University of Birmingham, the date range given for the parchment is between 568 AD and 645 AD, which overlaps more closely with Muhammad's lifetime. The dates and link have been fixed now in the summary. Historians say this new information highlights the uncertainty surrounding the emergence of such religious texts, rather than being a major upheaval.

You are certainly right about hate not being helpful at all.

It would also be good if the systemd-proponents would stop accusing anybody that does not like their gadget of "hate". It is just a transparent attempt to discredit
them and actually spreads hate as it produces a counter-reaction. Not good at all.
