  1. Re:Replication has been here for a while now on 3D Printing and the Replicator Economy · · Score: 2

    of course, replication without automation has been around even longer. My father worked in large U.S. tool and die maker that routinely used their milling machines to make more milling machines, with a lot of blood, sweat and tears of very skilled machinists. Amazing what they did before CNC, complex curves by various tricks of the trade.

I was once manager of a group that made power switching systems for buildings and military installations, and whenever Motorola would go into prototyping mode for new cell phone lines all my projects for transfers switch enclosure would get backed up, all the mom & pop prototyping shops for miles around Chicago would be backed up.

    Metal antenna can be made cheaper than their silly exotic inks, and are far more durable. For a few bucks, one can make a homemade conductive ink with graphite, fixer and solvent, that's an old kid's experiment from decades ago, can brush that stuff on clothing or paper or a wall and use as antenna or as wires to connect circuit elements. a bit more versatile than this article's ivory tower dweebs and their complicated way of making something less useful, more expensive, less durable....I give this ten RepRaps on a scale of pseudo-geek stupidity

    in the 19th century they had pencils that could put graphite on paper, you can draw your very own antenna (or circuit conductors) for less than ten cents of materials. You can make your own conductive ink too. These things have been part of fun science experiments for kids for decades, I did them 35 years ago. Steam engines are thousands of years old, by the way.

    Gee, an antenna converts radio waves to AC. This phenomenon has been quite well known since the 19th century. For something a little more modern, and a whole lot better than a fucking printed antenna, you can use a metal fractal antenna for wide band coverage.

  10. Re:Advocacy of SQL and relational model is a warni on Unified NoSQL Query Language Launched · · Score: 1

    No commercial database system fully implements the relational model, because parts are absurd for real world use. The tables of the relational model are a minuscule subset of the possible hierarchies, not the upside down world view you seem to hold, and the relational systems show their limitations in very poor query response against multiple levels of the data structures. The AI systems of which I speak have their recent origin in the late 90s, unlike the fossilized 60s systems (and moreover the ancient 1970s relational model) you mention. You are an advocate because that's all you know.

  14. Advocacy of SQL and relational model is a warning on Unified NoSQL Query Language Launched · · Score: 2

    You must have limited experience, relational model fits only set-based data well. There are plenty of hierarchical data structures for which the relational model is a terrible fit and give abysmal performance for both storage time and queries. I've seen this time and again in my three decades of working with relational databases. A client of mine has been working with medical AI systems for a few years, one early discover was relational model is absolutely an inferior representation for most knowledge base ontologies,

    It is you who have limited exposure with java if you haven't run into horrendous portability issues (out of the blue, ever use jaxp on weblogic for ppc?), or the backwards incompatibility issues between versions ( better check out that list for this latest release, by the way). Scalability is purely a matter of architecture, not language choice. I've worked on a fair share of massive code base projects. My choice of silly words for the IBM drones is just a nice way of warning about the consulting sewer that eats time, money and project deadlines, I'm 47 and you're welcome.

    But she had a PhD in mathematics from Yale; not your average person, male or female. She did more than develop successful programming language, she conceived of the compiler in an era of jump-wire programming, that's programming as we know it. And moreover the intention of the design of her language was to have something of which an intelligent non-programmer could follow the explanation as a simple quasi-english. And though we mock the successor, COBOL, of her language (which she also help design), remember that unlike most languages today it allows one to exactly specify representation in storage and disk, while now we struggle with portability issues largely revolving around lack of that.

    The person who first conceived of the compiler (and yes built some too) was a woman (Rear Admiral Grace Murray Hopper). Anyone who programs in a language, even symbolic assembly, instead of op codes should thank her.
