    Microsoft Internal Documents - Permanent Work From Home

    I am fortunate enough to have a hands-on job (mix of bench science and onsite engineering). We were allowed back into lab mid-June and my mental health/happiness shot through the roof, even though I had been pretty successful about doing meaningful work during the mandatory WFH period. WFH has...

    We've Long Waited for Fusion. This Reactor May Finally Deliver It—Fast.

    The joke/adage I've known is it's always 25 years in the future. But, yeah, I really *really* want to be wrong, but we've heard this before. At least ITER is building now!

    What is the best video card for under $150?

    Fortunately this one is a MSI Super Ventus. :) I am definitely loving the lack of noise and heat! Not quite the deal /dev/null/ found but I'm very happy about my purchase nonetheless.

    What is the best video card for under $150?

    You can see my thread a few down, which is very similar in scope. Tl;dr: just picked up a returned-to-Amazon 1650 Super for <$150, so keep an eye on things. You have to make your own value assessment on new vs used. I needed a card asap, so didn't have time to hunt used, but I'm sure I could...

    $150-$200 best value? 280x has died

    It's all good; thanks guys. Did manage to score a returned 1650 super for $<150 and Amazon already told me it's in the mail. I didn't necessarily have the luxury of waiting too long to get the best bargain since the machine is down until I get a replacement (I have a habit of running video cards...

    $150-$200 best value? 280x has died

    Thanks all -- you guys did seem to reinforce that that 1650 super is probably the best bet new in the price range I'm looking and the RX580 is the go-to used card. Sadly, a used GTX 1080 isn't in the budget, nor the 1660 super (which does seem like another good performer!). Appreciate the help...

    $150-$200 best value? 280x has died

    Had been getting some BSOD's lately and this morning the graphics card was throwning funky lines all over the place. Bought the sucker used in 2016, so I'm not too heartbroken. I have been living under a rock in terms of computer hardware so could use some help. Truth be told, I was pretty...

    Archivists Are Trying to Make Sure a ‘Pirate Bay of Science’ Never Goes Down

    I'm an engineering postdoc doing research at an academic hospital. I do not have access to many of my usual and relevant journals, but if I need anything clinically-related, we have a contract to supply it. The institution pays a huge amount for access to those journals and it makes sense for...

    Archivists Are Trying to Make Sure a ‘Pirate Bay of Science’ Never Goes Down

    There's a lot of private grant organizations that are now mandating publications funded through them have open access--HHMI being a big one in this realm. We're in the midst of a sea change in this regard. Similarly, you have things like this happening...

    Early TSMC 5nm Test Chip Yields 80%, HVM Coming in H1 2020

    AT: Intel’s Manufacturing Roadmap from 2019 to 2029: Back Porting, 7nm, 5nm, 3nm, 2nm, and 1.4 nm

    You make sure you don't need long metal lines for these ultra small feature levels, so you use heavier, higher resistance metals, eg. Ta, W, Cr that do not suffer from electromigration anywhere near as bad, then switch over to Cu BEOL. At least that's what I remember, been out of processing for...

    TSMC actual 7nm defect rate and therefore yield revealed.

    You're correct I flipped yield and defect density, my apologies. Although I haven't seen an official statement as to what TSMC is calling a defect; https://en.wikichip.org/wiki/defect_density leaves some ambiguity. A core disabling defect is different to a defect that renders an entire chip...

    TSMC actual 7nm defect rate and therefore yield revealed.

    Not likely that elegant of a "solution" to suggest it's all artificial fragmentation -- how they are reporting defects makes a difference. And with these dimensions, a yielded core will have variable performance, so there will be qualifications on that as well (e.g 2 dumpster fire, but working...

    How to Bypass Matlab’s ‘Cripple AMD CPU’ Function

    I was more going off of Mathworks lazy programming of blindly using the Intel libraries and not even doing a proper check for AMD processors to provide an alternate math library. I believe this part of Matlab code isn't exactly new, so it was done ages ago and never re-examined. Like it or not...

    How to Bypass Matlab’s ‘Cripple AMD CPU’ Function

    This sounds like lazy coding more than anything nefarious, but, hey, I'm a big fan of Hanlon's Razor. Hopefully Mathworks will fix their code base.
