I am confused as to why the price of platinum would spike.. Its not like they would need 5t in metal to make the coin. Thats the whole point. They can use $5 in platinum to make the coin and slap a $5T label on it..

Where does he say he wont hire someone with varied experience that included.net ??
Did we read the same article ?? All he does is say that.net experience causes him to ask "WHY"..
A quick quote from the article
Now let me clarify —.NET is a dandy language. It’s modern, it’s fancy, it’s got all the bells and whistles. And if you’re doing Windows Mobile 7 apps (which the stats suggest you aren’t), it’s your only choice. But choosing.NET is a choice, and whenever anybody does it, I can’t help but ask “why?”
And right at the end.. as a summary
So what’s the moral of this whole story? Two things:
If you ever want to work in a startup, avoid.NET. It does you no favors. If you are a startup looking to hire really excellent people, take notice of.NET on a resume, and ask why it’s there.
That is all.. he is saying to ask the question. It is the answers to that question that he is concerned with.
If you answer "Cause.net is da shit.. it does everything for me".. you dont get hired..
If you answer "Cause the problem we needed to solve was best handled by.net" then you may get hired.
Yea..Ok.. I understand what you are saying , However Its still not making sense as to why you would concern yourself with the extremes of the gear range , before you think about getting rid of ten pounds of dead weight.
The range of the commuter gears ( numbers used as per your comment ) may be from 1:4 to 4:1.. Your race class machine may be from 1:5 to 5:1
Without knowing the type of race to be riden ( As no details have been given about that ).. You are saying that having the extra range between 1:4 and 1:5 PLUS the range between 4:1 and 5:1 is more important then loosing what is likely to be 10 pounds of dead weight.
No matter what,. your greater range ( 5 vs 4 ) increase will be useful only during some subset of the ride. ( Likely only for large hills , either up or down )
The weight reduction would be useful for ALL parts of the ride.
Think about it a moment , it would not be a marginal amount of weight..
Some of the items on my commuter class bike that could be removed to lighten it up for a "race" would be
Fenders Package rack Tool kit ( including pump ) LOCK ( this is 5 pounds all by itself ) Kick stand Lights gps / phone mount
I think you may be underestimating the amount of weight that can be shaved off a commuter bike.
Are you making the assumption of a single gear commuter bike ??
My commuter class bike ( often refereed to as hybrid ) has 15 speeds/gears. I use , perhaps 3 or 4 of them.. But the range is there , both high and low.
What exactly would you change ?? give it a higher high gear ?? A lower low ?? How would that be better then loosing 10 pounds of crap ??
Your comment is not making sense to me. Please elaborate.

I sure do consider youtube the 21 century version of a printing press.
did you actually watch the show ?? It was one of the few that really tried to follow actually true physics. There will be no wormholes !!!
Remember it was all one solar systems.. They did REAL entries into the atmospheres. They did not just add in a "Faster Then Light" drive to get around , travel took time!.
In regards to the quad copter. The pics of my unit are in the pics section of that aero quad site.Go find them.. ( Thats about what you said in regards to the online shopping for the STM ). Yes I learned a lot about control theory ( PID and such ) and about prop efficiency and torsional rigidity of different materials. Did I learn anything about "micro controllers".. I learned enough to USE one to perform a function I needed done. I was not looking to build a production item for sale , I needed to do some math to control a motor based on an input from a gyro. This is where the niche that arduino fills. And it fills it well.
In regards to your "built a kit" comment.. I took what others have done before me , and I expanded on it. If you cant understand this simple concept , then you really are an idiot. Please do the world a favor , and never reproduce.
If you want to have a real discussion , feel free to respond. If you want to be an ass.. Go troll someplace else please.
One MINOR point.. Not trying to argue , I agree with your point in general. However that mcu + acc + sd card.. *"CAN"* be done with one.:-D The mega has pins / memory / serial ports to communicate and process all of that without any thought. In fact , I bet it could be done with a tiny pro with just a little bit of thought. Not to say that it will be the best one out there. But to put it in a box with a lipo battery and magnetic mount , you could log what your kid does with your car when you hand over the keys.. In fact , you could even drop a cellular breakout board into the mix and have it send real time ( I have done this:-D ) But if you "do it right" and design a board just for that product . It would be much MUCH cheaper.
One other key point. The arduino isnt a "development" board. it is the final product for most people that use them. They are not designing something for mass production. They are making something shiny that they will use themselves. As an example , last year for Halloween , I took an uno and a tri color led and made a simulated "candle" for my pumpkin. When I was done with it , I took it apart and used it for something else.
The cost issue.. No one in there right mind would use aurduino in a production product. At least not for anything more then niche markets of very low volume. I dont think that anyone has ever claimed this. This is an argument that the "real" devs are making assumptions about. With the above example , my better half loved the fake candle I made and suggested that we sell them. She does crafts and sells them on esty. I had to explain to her that it cost ME 20 bucks for the parts for that candle. So the retail price would have to be $50 or 60 to make any sort of profit. If I was to try and build something to sell , I wold have gone with a completely different chip. And have build a circuit around it for that one function and sent the design off to a fab.. and all of that stuff. Likely it would have ended up being under $1 per unit ( at volume ).. This isnt what its designed for. Not even for prototyping a unit like that. Arduino it is the final product.
If by that you mean "It just works".. Then I can agree. and that's not a bag thing:-D Because thats what its designed to do. Allow you to USE a microcontroller , without having to learn a microcontroller. As an example. A recent project of mine. I opened the package with the arduino ( Another similarity with apple , they include cute stickers:-D ) Ripped apart a Wii Motion plus controler. Strapped the innards of the WPM and the arduino to a pair of aluminum towel bars. Added 4 brushless motors and propellers. And had myself a working qudro copter ( if you dont know what it is , think helicopter with 4 blades and no moving parts besides the props ). See http://aeroquad.com/.. http://www.multiwii.com/ as another similar project. These are the kinds of things that the "it just works" portion is allowing.
If you are trying to continue the fallacy and say that they are "expensive" , then you are highly mistaken. There is NOTHING stopping you from downloding the source files for the board , and making your own. Not a thing at all. The only thing that you cant do , is call them "arduino".. you can advertise them as "arduino compatible".. and thy even encourage this. The entire project is open source. Perhaps you were not paying attention.. THE ENTIRE PROJECT IS OPEN SOURCE !.. Including all hardware.
Perhaps you tried to use the word gaming as humor. Apple is not known for gaming. I know I only use them to play starcraft , perhaps some wow. OH and steam has a bunch of stuff that will run on mac.Oh dont let me forget my "onlive" account also.. To play call of duty , or something like that. I sit on my couch.
( Oh.. and I was unable to locate this mystery board for $50 anyplace besides ebay.. And even there I had no idea what I was looking at. There were Items with penny starting bids.. and items with $270 buy it now prices..Also.. Not sure about you , but I tend to buy things from people I can trust. Not having to take a risk on some ebay shop.. Google shopping search for "STM32 development board " returns items in the low 3 digit price ranges.. 250ish.. )
Perhaps he is trying to simulate the flashing cursor during the load.
If we really wanted to nit pick on him.. You could ask why the,1.. unless his sig is "machine language" there would be no reason to load it directly into memory.
All the reasons the guy listed for why the Arduino 'wins' are not unique to the devices. You can get all of those same things out of a radio shack basic stamp.
Arduino won because the stuck a decent microcontroller on a solid board (I'm ignoring the absolutely retarded pin spacing issue that pisses everyone off) at a decent price with a serial boot loader already burned to the chip. The ATmega chips were popular long before Arduino, so when it came out suddenly all of us who had been futzing around with ATmega's for years finally had a source for a preassembled prototype board rather than constantly cobbling our own together. I've still got several PCBs I etched with a generic prototyping layout in my shop.
They took the need for an Atmel ATmega programmer out of the equation but otherwise you get just a slightly larger than the chip itself prototyping board.
The Arduino software is complete ass, the only reason anyone uses it is because they don't know there something better... like say... entering your code from the command line with cat > filename && cc filename. The libraries, while relatively easy to use are painfully slow and bloated for no reason, which is important when your counting clock cycles on microcontroller.
Arduino didn't win because its Arduino, it won because it used a microcontroller that had already cornered the market.
There will multiple ATmega chips (the ones used in the Arduino) in every household before the Arduino came into existence.
Basic stamp from radio shack.. 100 bucks.. Needs a rs232 port for programming.. Who has a system with them anymore ?? Do you ?? I Dont.. I have to use a usb / 9 pin connector if I want old school serial. Include some stuff like a servo and some leds and resistors.
uno invetors kit from sparkfun.. 60 bucks.. any old usb cable Also includes "stuff"
That retarded pin spacing is a feature. Prevents you from plugging in a "shield" wrong..
Also , and this is most likely the big reason they are doing so much better then the rest.
They are 100%.. completely open source. If you want a different pin spacing.. You can go and download the egale files ( or gerbers if thats your fancy ) and fab a board with your own pin spacing if you want.. Hell , you can even SELL that modified board if you want. If you really think its retarded , you can do make your own.
A pro mini ( assembled and tested ) is 18 bucks RETAIL..
Please show me the link where I can buy this contiki for $3 ( assembled and tested )
Now please show me where I can get this 32 bit arm board with MB of flash and ram for 40 bucks ( assembled / tested ) and with software to program it. Heck lets go for your 3X price tag so 60 bucks..
Arduino isnt meant to be used in a production item. for a production item , you design the circuit and use just the processor / controller . Not the same world.
For the amount of money they cost ?? 65 bucks for a completed 2560 with usb interface.. Completely assembled and tested.. You think thats alot ?? INCLUDING SOFTWARE TO PROGRAM IT !!! 20 for a tiny pro with a 328. Its a 4 layer board assembled in Italy buy people that make a wage that they can feed there family with. Not a dual layer board put together by slaves in china.
The adruino guys make almost nothing board.
AND ITS ALL OPEN SOURCE.. if you think you can do better , you are welcome to go download the exact eagle files that they use to fabricate the board. And sell them yourself.
Have you even looked at what some other avr boards cost ??
Also , they are reflow soldered. There is no "solder work" to speak of.
I have YET to come across these "quality control" problems you speak of. I have on my bench right now a mega 2560 delivered within the last 2 weeks running a led matrix of 256 leds , and its been running now for at least 18 hours with no problems.
From my first duleminove through the half dozen tiny pros ive used.. to a mega 1280 last year.. to the uno I got before Christmas , and this latest 2560.. They have all been 100%

Do you know how many people died because of fires and rear end collisions in the pinto ..
Twenty seven. ( The same number that is attributed to a transmission defect in the same range of cars )
The reason there is a story , is because Mr. Nader needed an issue to sell his book.
Go research the issue for yourself before you go on spouting conjecture.

Likely he is just stuck on the fact that advertisers traditionally pay the biggest bucks for channels 2 through 13 ..
Thats physics made FUN !!!!
