Really interesting article. Wish Myhrvold's research had been available in 2013, seemingly the last time the Senate Commerce, Science, & Transportation Committee (jurisdiction over civilian space issues, i.e. NASA) had a hearing o

Disclosure: I work at Intel and submitted the post. Dormando mentions the test was done with the help of Accelerate With Optane, a collaboration we have with Packet to provide access to servers with Intel Optane SSDs. Check out https:&#x2F

If you add a new storage tier which is supposed to be cheaper than another tier but also slower, you can't take it for granted that real life performance is better. For Facebook which has talent on hand and a very large scale to amort

It looks like the research team has submitted some commits for parts of their work from the paper to be merged into RocksDB at large. If the work is shared for others to use, it shouldn't be so scary. https://github.com&#x2

Interesting but seems kind of late, no? Even the US State Department has banned USB drives since at least 2008. I don't think US government is particularly well known for being good at security.

I'm guessing OP is asking about market analysis in terms of evaluating whether a business idea is good (or not), not market analysis for investing. E.g. what is the market for X product (units and revenue), who are the competitors, wh

Does the presence of a HDD or SSD across the three architectures make a difference, or is this purely a CPU problem to be solved? I see the testing made sure to fit all tables in memory with a large enough innodb buffer pool, so was storag

Is there a TL/DL for that segment? Going backpacking this weekend and this whole forum has me worried...

Have you been able to get access to / test the server version of Optane? Looks like Facebook and Stanford did some research with it as a DRAM replacement in MyRocks DB: https://dl.acm.org/citation.cfm?id=3190524

Ahh thanks for letting me know. No chance to delete it now but the submission links to the abstract and the PDF can be accessed there.

NVM (non-volatile memory) is a reference to Optane SSDs in this case. Direct link to the PDF is here (pardon the ugly link): http://delivery.acm.org/10.1145/3200000/3190524/a42-eisenman...

Awesome. I've been checking out the site on the wall time submissions especially. To the point of the original questioning, do you know what's under the hood on the machine you're using to test at perf.rust-lang.org? I&#x27

Thanks, Steve, for the response. Certainly there are a lot of variables so I'd like to see benchmark reports actually disclose what's under the hood. Let's say, for example, you're on a regular rebuild cadence for your

Total noob question here, but how does the hardware you're using affect compilation speed? What's the baseline hardware being used in this benchmark he runs? There's no way to recreate the benchmark environment unless we kn

Can anyone explain why their operating margin is seemingly seasonal, improving through the year? And damn, that tax rate is insanely low. Looks like they're settling into around 10% effective tax. Average across profitable companies

I'm in this boat right now. I'm lucky to have a very short commute today, but for personal reasons I may need to move where I'll have a 90-120 minute commute. It's to the point I may need to switch jobs or companies to

Totally agree, but I'm not convinced that tech job security is as solid as HN or VCs like to think. I'm trying to get at defining what "tech skills" means. It's such a broad term!

I searched through the article and didn't see much discussion at all on storage as a bottleneck. If it actually is a bottleneck, is color grading more of a sequential or random data access workload?

Congrats! What do you think about the seemingly more common approach for newer grads to work 2-4 years per job and then move on? I hear MBA grads on average stay in their first job ~18 months. It's around the same length for software

I'd be curious to ask you what "tech skills" means. What's demanded by the companies you refer to is likely shifting constantly. If you're not working in the hot stack, you're not going to have job security &q
