So, there are multiple GPS signals. Originally there was a C/A code (on L1), and a P code (on L2). The C/A code is used by civilian receivers, and both codes are used by military receivers for increased precision. There used to be a pseudo random uncertainty added to these codes that required special keys to correct, which only military receivers had. This was called "Selective Availability" and was disabled May 1, 2000. The newer GPS satellites have even more codes which increase accuracy, including some available to civilian receivers.
So, the military does still have more accurate GPS than civilians, but there is no longer an INTENTIONAL error added to the civilian side. Newer GPS satellites and newer receivers include more and more technology to get more accuracy even on the civilian side, though. Most modern GPS chips support multiple systems, including GLONASS, GNSS, and others which can be combined to increase accuracy. I am not sure how this new Broadcom chip works but it is probably a combination of the newer signals and the combination of multiple systems. GPS on cell phones is typically integrated into the cellular modem itself and can make use of location data from the cellular network to help as well.
Is the upgrader really that bad? I have a Ubuntu server that's been around since 2010 vintage and upgraded to every-single-release between now and then. It should be pretty much the same thing IMO
When I am learning a new language, I usually try to think of something cool to do, that would be pretty difficult, and then challenge myself to actually do it. Using the many resources available on the web you should be able to figure out any problem you run across. I am personally more into utility type apps, so that's the sort of things I have done, but if you are more into games or whatever you can do that too.
You realize that the Macintosh came after the Apple II, just as the iPad came after the (modern) Macintosh. The comparison is saying the newer platform cannot run the stuff from the older platform.
As he says, not all CD players are made equally. If you have ever listened to much music on CD, you will have heard what happens when discs can be read but not properly. If you are fairly young then you might have little experience with actual CD's though.
In any case, it's very obvious to me when a CD player has to interpolate data.
Don't forget he is changing the cables in a DIFFERENT PHYSICAL BOX than all of the later analog domain stuff. There really isnt any way that any electronic field that can/may be emitted from the SATA cables will have any effect on the analog components later down the line. Due to his testing method he physically eliminated that possibility. If it was all in the same box, I would say yeah maybe this could have an effect, but the carrier frequency of even SATA 1 is 1.5Ghz, WAY WAY WAY beyond audible range. If there is a source of RF noise infecting the analog part of the circuit, it's coming from something else.
When you have uncorrectable errors on an audio cd, you do NOT get 'subtle' changes, you get very nasty sounding pops, clicks, and things that clearly indicate that there is a problem. It's not a matter of one sounding better than the other, it's a matter of one working and the other not.
Even SATA 1 uses a 1.5Ghz carrier signal. That's NOT going to affect your audio. Frequently, however, there are other sources of crosstalk which can infect the audio, but the solution to that is a better or external sound card.
When you use a phone that supports UMA and have TMOBILE you can do this. For example, on my blackberry I can disable the mobile network, and have ONLY the wifi enabled, yet still place calls and send/receive text messages. Look up UMA. Cool stuff. Doesn't cost anything extra either.
Warranty replacement should still count as the lifetime of the device. I think that they are being rather cheap about it there. Say you had a lifetime transmission warranty but the transmission went out, well guess what it's lifetime is over and now it wont be replaced. Would you like to have that happen to you?
No, the very easrly versions actually have more ram & flash than the GL version. I have a v2.0 at home and it has 8MB of flash and 32MB of ram. I believe the GL only has 4MB of flash and 16MB of ram.
I believe that they were referring to the fact that initially 10K disks were only available in an enterprize SCSI platform, where as now you can get a 10k drive in SATA flavor, not that SATA has replaced SCSI.

Not when there is an easy way to prevent the outbreak!
Mod this UP! !!

He was talking about an R-Pi which only BARELY qualifies as an embedded setup. Tyically I am thinking AVR, Cortex-M, PIC, etc when I hear 'Embedded."

even hack.box.sk before that
LOL, the term "you can get this nicer toy microscope on Alibaba" .. NEVER HEARD BEFORE!!
Lol, DX11 videos, yeah...

Still is a terribly slow processor.

Hrmm, lets see, 10 years ago you should have been able to get a 600Mhz p3. So, yeah, a 60Mhz PPC IS terribly slow.
It's the same RAM chips, but there are just 9 chips on each stick, instead of 8 (or 18 instead of 16). It works just like raid 5.

that they are using an ancient system to do the tests? I wouldn't be surprised if the system itself is a limiting factor with some of the SSDs. Crazy.
Touche.
