Submission + - Affordable 3D metal printer developed, opensourced (techienews.co.uk)

hypnosec writes: Researchers have developed and opensourced a low-cost 3D metal printer capable of printing metal tools and objects with cost under £1,000. A team of researchers led by Associate Professor Joshua Pearce at the Michigan Technological University developed the firmware and the plans for the printer and have made it available freely to anyone interested in taking this further. Built with cost of just £913, the open source 3D printer is definitely a huge leap forward as the starting price of commercial counterparts is £300,000. Pearce claimed that their technology will not only allow smaller companies and start-ups to build inexpensive prototypes, but it will allow other scientists and researchers to build tools and objects required for their research without requiring to shell out thousands. The associate professor also claimed that using the technology, countries can use it to print components and parts for machines such as windmills.

Submission + - Bringing Chemistry Back (kickstarter.com)

IcephishCR writes: The Kansas City store H.M.S. Beagle has a funded Kickstarter campaign to bring back an item I always wanted — but has remained unobtainable from before my youth: a Gilbert Chemistry set. The Benchmark set contains 64 chemicals that the near-useless set of today fail to include.

"Like many young scientists of the time, I received a Gilbert Chemistry set. This chemistry set provided me hours of great fun and learning as well as laying the foundation for my future as a research chemist. As I became an adult I wanted to share these types of experiences with my daughter, my nephews and nieces, and friends. But soon I became aware real chemistry sets were no longer available. Without real chemistry sets and opportunities for students to learn and explore, where would our future chemists come from? So .... I set out on a mission."

Based on my recent experience with an illness, this is exactly what you will have to do if you ever fall out of the normal bounds of straightforward illnesses. You will be managing your own treatment and trying to piece together what's wrong with you. You will burn through doctors and specialists one by one as they say they cannot help and refuse to let you make appointments. You will end up being the only person on the whole planet who cares and all the time you will be doing this when you are sick and/or drugged up. You will also realize that the whole health care system does not work like JIRA and that there is no follow up and your issue will be dropped if you don't continue to be the squeaky wheel. Health care is not engineering. It's scary how few engineering best practices are used in it and how full of holes the "system" has. Healthcare is probably about 40 years behind engineering in terms of problems solving and issue resolution and about a million years behind understanding how our bodies work vs "complex" systems we diddle around with all day on computers.
Moral of the story is - don't get sick with anything weird otherwise you're basically toast.

Comment Online vs offline (Score 1) 73

As a hiring manager, I would not care if a candidate had completed their degree online or offline so long as it was a real degree (we can test some things, but the whole point of a qualification is that it's supposed to mean something). However, there seems to be a big reluctance by established universities to give degrees based on these online courses so far. What needs to change for that to happen and will it ever?

No, they stopped selling them because transflective displays are limited by resolution. You can still get cheapy phones with them in Asia, but smartphones with HVGA or greater screen resolution don't have the space for the extra reflective part of the pixel that is required. One compromise is to use monochrome for the reflective part, which is what you see on the MotoACTV and WIMM smartwatches.

Comment Sapphire - Corning's Nemesis (Score 1) 175

Corning's on a marketing offensive against sapphire, which is up and coming as a cover glass material. It's massively stronger than Gorilla (TM) Glass and so can offer better protection for the same thickness from impacts (although Corning will argue the opposite). The main problem has been that it's been expensive, but for some applications it's perfect (I'm looking at you smart watches) and the price is coming down, down, down.

I've hired gray hairs, long hairs, dyed hair and no hairs as programming contractors. Age and experience are not so important to me for these mid-level programming gigs.I care about a few things though - are you up to date on not just coding, but contemporary development methodologies? Have you worked in an Agile team before? Do you have a niche skill that fits with my project (in my case often embedded programming, or Linux device drivers). I'm far more interested in what you've done in that last year before you came to me, so work experience is important. We *will* check if you can program and what approach you take to solving the type of problems we have via multiple interviews on the same day, so if you really can't program, then you will be found out. Also, we place a lot of weight on recommendations, so if you have worked with others on a team and they vouch for you, that will help a lot. Finally, if you are a jerk personality-wise, then we won't want you. Having been burnt more that once by hiring people with serious personality issues it's one of my top things I try to weed out at interview. Finally, a good agency might help you - they take a nasty cut, but push their employees.

Android is a gift, not a product. Android needs fixing to work properly because it doesn't work out of the box. Why? Because hardware changes from OEM to OEM, the government require mandatory support for features that aren't included, the customer (AT&T etc) require support for their apps or services, some very important ones, and last, but not least, it's buggy.

Details:
It takes about 6 months for a dedicated SCRUM team to knock a version of Android out that meets a major US carrier's requirements after Google releases their code to the community. I know because I've done it. Verizon has about 6000 requirements for their devices, Sprint and AT&T are not far behind. On top of the carrier requirements, which could be anything from implementing a custom address book sync adapter, to ensuring AGPS works accurately, you need to meet US Government requirements. CMAS is a great example. Further, there may be a stack of accessibility items that need to be done, although, Google dramatically increased their support there from ICS. So, once you've done the carrier requirements and the regulatory ones, you also then need to fix the bugs. These could be part of the open source - just look at the issues at code.google.com to see the outstanding ones, or they could be the result of the changes your chip set supplier made to have the code work with their hardware, or their proprietary codecs, etc.. Google may not have gotten around to fixing their bugs yet, but that doesn't mean you'll be able to ship a product today with without fixing them. Should those fixes be pushed back to the open source tree, absolutely, but are they? Why let a competitor benefit from our hard work? Also, you need to weed out any bugs that are unique to your hardware configuration - that could be caused by touch screen firmware, or the modem, bluetooth, or some other piece. Then, finally, you can decide if you want to reskin the UI or add your twiddly improvement. Sometimes that's an enhancement that customer's expect, like hyphenating dial strings, or sometimes it's a totally sexy homescreen widget. That part gets all the press, but all the other stuff must get done even if you decide to ship "pure android".
