Printing shower rings in a 3D printer is not a quick process.
Typical numbers might be 30 minutes set-up (download, heat up and slicing) + 30 minutes each x 10 rings x 1.25 (failure rate) = approx 7 hours. Granted you dont have to sit there for the whole time, but you do have to nurse the printers through quite regularly - tweaker the slicer, clean up failed prints, remove finished prints. They're not as set-and-forget as poeple might think.
I actually feel sorry for the taxi drivers. It's not just a threat to their business - they are being undercut in ways they are not legally able to compete.
Taxi licenses cost big money, and that has to be recouped. The cars have to be maintained and inspected, and that also costs. When someone uses their personal verhicle with no other on-costs, I can see how taxi would get upset.
Try showing some compasion for a while. This is not as simple as the little guy versus big business.
Easiest solution is to install an intercooler that will chill the incoming air before compression, or reheat the outgoing air when it is being released. A big heatpipe sunk into a significant thermal sink (the ground) would do this fine.
I've tried a few times to do unattended long prints on my Solidoodle but often enough something goes wrong partway - not only is the print ruined but a heap of filament gets wasted. Generally I stay close by and work on something else, and a couple of those times I managed to catcha problem that might have damaged the printer (e.g. snagged filament).
Anyway, it's not completely dead time, but it does require a fair bit of nursing. Im slowly improving some of the mechanics and operating parameters so maybe it will get better, but it's far from foolproof yet.
A DLNA device can be both a client and a server, and you can instruct servers to play content you have chosen. I'm pretty sure I've done this XBMC's DNLA implementation, controlled from my PC.
If you're grey haired, experienced and accomplished, you should also have a friendly network of ex-colleagues and customers who will help you get a job.
Your first job or two you should apply for though normal channels. After you've made some friends in the industry, every other job you should either be getting shortlisted though mates referrals, or headhunted - it's that easy. Employers are screaming out for good employees and the internal referals count heavily compared to unknown randoms.
Visible, Infrared, Microwave, and Radio can all cause heating (it is energy after all), but this is not ionising and not considered damaging unless it exceeds your body's thresholds for temperature regulation.
Microwave and Radio can penetrate deeper and create heat through a dielectric effect, but the end result is still the same.
The lime actually protects the steel rebar. Lime, being alkaline, wants to perform a reducing reaction, actually reversing oxidation on the steel.
The problem comes when the concrete has suffered significant leeching - the protective alkalines get stripped away and there is nothing protecting the rebar. You can see this readily when the rebar is too close to the surface as that's the first area to leech.
So? Even with LCD's I'd rather a PC that can push 75 FPS.
If your PC is capable of pushing 75FPS and the monitor can do n60, that's great. The frame buffers will always be full and you'll have nice crisp graphics with v-sync turned on.
If the PC is a bit slow (or there is a demanding section of the game) and the system can only do 59FPS, it will be nasty as you'll drop frames regularly.
Go and have a look at the metabolic pathways that yeast use to glean energy from sugars in wine/beer. It is truly staggering, and temperature, PH, timing and yeast variety can all play a part in preferentially modifying those pathways. As a result, there are a bunch of fermentation by-products, including different alcohol groups and esters. For example, I'm a beer brewer, and belgian yeasts are noted for producing "lolly banana" esters.
There is also a legitimate difference between cheap and expensive wine techniques - time spent cellaring, new versus second hand barrels, preservatives etc.
At the end of the day though that doesnt make a lot of difference - peoples tastes vary wildly and If you personally like the way it tastes then that's great, go buy it again. Whilst there is no such thing as a "cheap" or "expensive" flavour, if lots of poeple like the way it tastes, then you can call it "good" wine. If lots of poeple say it tastes like arse, then it's "bad" wine.
That is one of the funniest things I have read for ages!
Power supplies are dealing with 700+ watts at maybe 90% efficiency, and you describe them as "pretty cool"? Bollocks! Capacitors and Inductors have current flowing and series equivalent resistance, which certainly generates heat. They *should* certainly be hotter than ambient, which is the most important factor in condensation.
If I saw condensation on powered electronics components I would be looking for the ladder to climb out of the pool.
Even business class will give you metal knives and real glassware.
Not that it matters, the plastic knives they give the cattle class can still do plenty of damage, I'm sure you could make a real mess of someone's throat with one.
No, it's not. Real boats have demonstrated that they can get to some downwind point (velocity made good) faster than the wind speed. Racing boats do this all the time.
Get a grip. Freedom of speech does not cover harrasment, and was never intended to. It's supposed to be about freedom to express your political views without fear of repercussion from the government.
Taking videos of drunk teenagers and then posting it for all to see on the internet is a gross violation of privacy, verging on criminal harrasment. Whilst the bullies are not to blame for her death, they certainly contributed.
That said it's pretty much got nothing to do with Facebook and everything to do with the parents of all of the teenagers involved - the victim and the bullies. Why were they not monitoring their children's online behavior?
Considering that the feild only extends a few millimetres between the charging pad and the receving antenna, I'd say none.
You're on a tech website, use your brains and have a rational think about it. Inductive charging is the same as a two transformer coils, slightly seperated into the base and device instead of wrapped on the same former. They would be using high frequencies to minimise the number of turns required on the coils, maybe as high as several hundred kHz.
This means any potential EMF leakage is well below the RF level, and non-ionising.
An hour in the supermarket once a week, and half an hour every night to cook is somehow "incredibly difficult and time consuming"? You probably spend more time on facebook.
Even better, if you learn to love cooking, it will become one of those "enjoy other things in life". Cooking can be immediately gratifying, as well as eating better you'll be happier and will impress others.
Agreed, but the article isn't about "home use", its about a brewery. Even with a microbrewery, just about anything else will cost way more than $100 (stainless vessels and fittings arent cheap), so in context a cheap PLC is quite resonable. If you have a larger brewery, then an expensive PLC is even more justified.
For the record, I'll be using a $12 arduino clone for my home brewery to do temperature/mash control. I struggle to see how you'd do it using a PC - linux or otherwise - without paying as much or more for an I/O interface.
Yeah but separating the control from the visualisation is a a good idea and generally considered best practice. Keep your control code small, fast and bug free; move the complex visualisations somewhere else.
If you want to hack together some automation around a linux PC then go nuts..... but to then make a website and video about how awesome it is? Really??
PLC's have a been around for years and many are dirt cheap - $100 CPU's and less than $10 per I/O. You wont hit memory limits in them (not in a brewery anyway) and they will run all day everyday doing one thing only, but doing it really well. The modules are easily replaceable which minimises downtime, and most of them use a standardised language (ladder logic) so that the next guy that comes along can understand it too. Now that is obvious.
If you want to fiddle more than that - and most poeple do - PLC's integrate with PC's just fine via Modbus (serial or ethernet) so that you can read or write data from them. Common packages to integrate with them are supervisory control systems (SCADA) or a data historians. There are plenty of commercial packages out there - Wonderware, Citect, InSQL, PI etc, and even some open source ones - http://openhistorian.codeplex.com/ and http://openscada.org/
Beyond PLC's/SCADA is the world of DCS (Distributed Control Systems), but you'd better have a spare million dollars and tens of thousands of I/O to justify putting one in.
It's great to tell your mates about how Linux is awesome but don't get too carried away.

P.S. - I still think 3D printers are awesome, but most of the time the unit I have at home (solidoodle) is a solution looking for a problem.

I wish I had mod points. +1 Insightful.
This is my favourite explanation yet :)

We used to call it "rental".
Gotta love "as a service" buzzwords. They have come full circle now :)

Farking security theatre.
The pilot radios the nearest airport, lands, and the SWAT team takes over?
No, it's not. Real boats have demonstrated that they can get to some downwind point (velocity made good) faster than the wind speed. Racing boats do this all the time.

Yean, not at all like cramming 250 people into a flying aluminium tube for 12+ hours with poor air circulation.
Seriously?
