<p>"Seamus Blackley apologized on Twitter to the AMD engineers who worked with Microsoft to create the prototype Xbox consoles that the company used in the lead-up to the OG Xbox's release in November 2001. To AMD CEO Lisa Su, Blackley said, "I beg mercy."<p>"I was standing there on the stage for the announcement, with [Bill Gates], and there they were right there, front row, looking so sad," he said of AMD engineers in the room. "I'll never forget it. They had helped so much with the prototypes. Prototypes that were literally running the launch announcement demos ON AMD HARDWARE."<p>"I felt like such an ass," Blackley said."<p><a href="https://www.gamespot.com/articles/20-years-later-xbox-creator-apologizes-to-amd-ceo-for-last-minute-switch-to-intel-pure-politics/1100-6496996/" rel="nofollow">https://www.gamespot.com/articles/20-years-later-xbox-creato...</a><p>Wow.

<p>The engineering teams were probably running both programs in parallel.  I've had this happen to me several times.   Sometimes, project B is just leverage [1] so that a better deal can be negotiated, so you half-ass project B, and that's fine and just business.  But sometimes it's not, and that situation sucks.<p>[1] Factory resources are scarce, so it's obvious to the engineering team how serious management is about things.  Word spreads.</p>

<p>That's kinda what I was thinking too.  There is a privacy loss for sure, but the average consumer also gained things for that loss.<p>Maybe Amazon in 2000 wasn't so icky but there was also no free same day shipping.  Apple II could be repaired without "special tools" but those machines were huge, heavy, mostly empty space, and gap and glass alignment was way worse.  I wish I could say something smart about Windows 95 but I've worked hard to erase it from my memory, so I can't. :)<p>Electronics things, just in general, did a lot less in the past.  With that comes good and bad.<p>Privacy is a trade-off and right now the general public doesn't place a high value on privacy so they're happy to trade it away for anything.   Honestly I understand it.  I'm convinced I'm going to get bombarded with marketing nonsense regardless so I might as well get something for it.</p>

<p>I just remembered your article on the standard cells of Pentium and there you noted bicmos was used by some gates for a reduction in propagation delay in some instances.  Were any of the gates in the adder structures bicmos?</p>

<p>A difference in potential between grounds in industrial settings is also really common.   Especially if one plugs two different pieces of equipment into two different branches of the building's circuit, without knowing it, and then connects those devices with something like ethernet.  With 20m+ cables, it happens. :) You'll be very happy for isolation then.  1 to 5V difference is enough to damage electronics.</p>

<p>There is a huge amount of software in every single step of making an ASIC, digital or analog.  Or even a PCB for that matter.  Long gone are the days of cutting tape and etching anything yourself.  Apple's M3 has 25 billion transistors.  No human drew those.</p>

<p>Maybe not privacy in general but this is about location privacy.<p>If you have a smartphone in your pocket, then, for better or worse, you're carrying a location tracker chip on your person because that's how they all work. The cell phone company needs to know where to send/get data, if nothing else.<p>It seems disingenuous to put a tracker chip in your pocket and be up in arms that someone knows your location.<p>Unless this kerfuffle is only about Apple.</p>

<p>> Do you consider this feature to be a violation of your privacy, requiring an opt-in?<p>I suppose in some sense it is, as it a reverse-geo lookup service, but it's also no where near to the front in the location privacy war.<p>Cell phone providers basically know your exact position at all times when you have your phone on you, credit card companies know basically everything, cars track driving directly, etc. etc.<p>I can see why some people would be up in arms but for me this one doesn't feel like missing the forest for the trees, it feels like missing the forest for the leaves.</p>

<p>Thank you so much for asking, I have oh so many requests...<p>Personally, I'm mostly interested in the ARM vs RISCV compare and contrast.<p>- I'd be very interested in comparing static memory and ram memory requirements for programs that are as similar as you can make them at the c-level using whatever toolchain Nordic wants you to use.<p>- Since you're looking to do deep dives I think looking into differences in the interrupt architecture and any implications on stack memory requirements and/or latency would be interesting, especially as VPR is a "peripheral processor"<p>- It would be interesting to get cycle counts for similar programs between ARM and RISCV.  This might not be very comparable though as it seems the ARM architectures are more complex thus we expect a lower CPI from them.  Anyway I think CPI numbers would be interesting.<p>I could go on but I don't want to be greedy. :)</p>

<p>It feels bad to loose but you also need the wins to feel good.  Beating a low ELO player is about as fun as beating small kids at basketball or something. For me it’s not the win/loss that drives me but making fewer mistakes.  If I loose a game where my opponent punished a minor mistake, fair enough, that took skill and I’ll learn from it and I don’t feel bad.  But if I loose because I made a blunder (obvious tactical error) that sucks and I hate that.</p>

<p>As a chess aficionado and a former tournament player, who didn’t get very far, I can see pros & cons.  They helped me train and get significantly better than I would’ve gotten without them.  On the other hand, so did the competition. :) The average level of the game is so much higher than when I was a kid (30+ years ago) and new ways of playing that were unthinkable before are possible now.  On the other hand cheating (online anyway) is rampant and all the memorization required to begin to be competitive can be daunting, and that sucks.</p>

<p>> If TPU's are really that good why on earth would google not sell them.<p>nVidia sells nearly 4M GPUs per year.   Google claims like 100K TPUs.  Scaling a production line by 10x is very difficult and Google has not shown aptitude in this area of expertise.<p>Even if Google wanted to scale 10x I'm not sure they could.  nVidia is believed to be taking like half of TSMC's new capacity (existing capacity is not idle).  I suppose technically that means the other half could be consumed by Google but it's likely TSMCs other customers wouldn't appreciate that.</p>
