I just hopped onto the Raspberry Pi bandwagon. I received two boards over the weekend (made in China) and both can't keep the USB/Ethernet on... I'm the last post in the parent's link....
It's very frustrating (even for an experience electrical and computer engineer) and I hope that they can get their quality control under... control. I'd hate to see something as awesome as the Raspberry Pi ruined during it's early life because of poor hardware manufacturing.
Without RTFA, I expect this recent post is to get some good PR out about the recent glut of defective boards.
But what about the price performance? These devices are all priced at the same level or even above than the iPad. All things being equal, the larger market of the has a network effort bonus that maks the iPad appear more valuable. Even the summary states these tablets are, "every bit as capable", in the technology sense, meaning the tech between the two is basically even.
Once these Android tablets can offer a device cheaper than an iPad, then we can talk about serious competition.
The 0s and 1s are still distinguishable because HDMI uses transition minimized differential signaling (TMDS). Basically, noise is picked up on all the wires and therefore can be ignored.
This sounds like local field potentials (http://en.wikipedia.org/wiki/Local_field_potential). Forgive me, but I fail to see how the summary concludes that other radio waves and "electronics" can impact this.
Maybe I should RTFA, but there seems to an obvious bias in this study. Framingham, Mass is cold, maybe women (and men) do better here when they are stockier since they have less surface area to lose body heat from.
Or maybe I am just bitter about the cold weather out here.
Every post here is hailing IMAP as the solution, yet I have not received one email on my imap account all morning.
I checked gmail.com and all my messages are still waiting for me.
The real solution is to lock your email server in a closet and disconnect it from any network. It's the only way to ensure your email is there.
I don't know about you but in my computer I only have 2 slots for RAM.
This device makes a lot of sense to me as I have been pining for a DDR2 version of this device for quite some time. Mainly because DDR2 is dirt cheap compared to other memory modules.
A whole lot of nuthin huh, not every story needs to be about the imminent destruction of Earth.
My hats off to the engineers who designed and built the LHC. Over 20 years of work deserves some recognition... Congrats to my particle smashing overlords.
I think the point is missed. This technology can exist on the microchip, thereby avoiding any additional fan to cool the chip. (Albeit it mechanical, water-cooled, or yes even ionic wind CPU coolers [very cool indeed]). That's news to me.
For example the xbox SDK was only available to elite developers. XBMC is an awesome program that has been forced into the underground because they are not an official SDK developer, even though their product is IMHO way better then anything Microsoft sanctions. Same thing happened to Nintendo in the 80's.
But the XBOX is my device and I can do what I want with it, but Microsoft isn't going to support it. Java, Firefox, and Skype can all be ported to the iphone (anyone heard of Installer.app), it just won't be supported through their software distribution channel. While I think it's a shame, it's their right.
Finally for those who say they can't hack this device, they certainly haven't tried. (IRC anyone?)
Oh and if Apple's TOS say it's illegal for me to run a ported Java, they can try and stop me, right after they pry the phone from my cold, dead, body.
1.4W/Kg !!! That type of electromagnetic radiation will effect anyone. A typical cell-phone radiation is well below 1mW/KG and probably closer to 1uW or even smaller.
This study proves on thing. Moderation is the key.
The problem with block downcoverters is that that is not truly a software radio and limits flexibility immediately, by reducing the spectrum available. This is the limiting factor of an modern day SDR system. Without the block downcoverters though it's hard to keep unwanted signals out (CDMA with a higher signal power then WiFi for example). But with modern day hardware and signal processing capabilities a novel prefilter can be designed, say with 20MHz tuning blocks that are to be completely digitized by an ADC (at a reasonable amount of power, say 10uW).
Actually this system is superior for just that reason, it works well in an urban environment. You wouldn't be able to get that from reading the Popular Science article, but check out the website for BMS (http://www.biomimetic-systems.com/, check under technology). It has to do with the fact that it uses a biomedical approach unlike conventional devices of this type.
Those devices, like you said work well in a laboratory environment but fail miserably once you remove them their happy place!

Let's hope they push relevant information and not drugs and booze.

Basically, it's using a form of Low-Voltage Differential Signaling
The lazy person's CAT5 to HDMI. This saved me a lot of trouble, and maybe will help you with your rats nest. monoprice HDMI to CAT5

Until you get caught, then cleanup's a bitch.
