Matt sent in this interesting article about Intel and disruption. He might not have realized it at the time, but when Grove was reading Christensen’s work, he wasn’t just reading about how Intel would go on to conquer the personal computer market. He was also reading about what would eventually befall the company he co-founded, 25 years before it happened.

Also making the news recently was a phone-home concern in MacOS. It turns out that in the current version of the macOS, the OS sends to Apple a hash (unique identifier) of each and every program you run, when you run it. Lots of people didn’t realize this, because it’s silent and invisible and it fails instantly and gracefully when you’re offline, but today the server got really slow and it didn’t hit the fail-fast code path, and everyone’s apps failed to open if they were connected to the internet. However, here's a rebuttal and explanation of what OCSP is and does.

On a similar note, Google are accused of chewing up data allowances on Android devices, by reporting home excessively. Users cannot turn off Android surveillance, which uses “valuable cellular data users have purchased.” Moreover, Taylor claims, “Google does this, in large measure, for its own financial benefit, and without informing users or seeking their consent.”

PayPal have enabled cryptocurrencies for US-based customers, with the rest of the world presumably to follow. In October, PayPal had first announced its plans to enter the cryptocurrency market by way of a partnership with cryptocurrency company Paxos. This partner helps to power the new service for PayPal, enabling its customers to buy, sell and hold a range of cryptocurrencies — initially including Bitcoin, Ethereum, Bitcoin Cash and Litecoin.

Highpoint have updated their NVMe RAID cards for PCIe 4.0 and up to 8x M.2 SSDs. Even though these cards are the best way to get lots of M.2 PCIe SSDs connected to mainstream consumer platforms that don't support the PCIe port bifurcation required by passive quad M.2 riser boards, the pricing makes it very unlikely that they'll ever see much use in systems less high-end than a Threadripper or Xeon workstation. However, Highpoint has actually tested on the AMD X570 platform and achieved 20GB/s throughput using Phison E16 SSDs, and almost 28GB/s on an AMD EPYC platform (out of a theoretical limit of 31.5 GB/s). These numbers should improve a bit as faster, lower-latency PCIe 4.0 SSDs become available.

TechSpot have a Ryzen 5000 Memory Performance guide. Earlier this year we compared Intel's Core i9-9900K and Ryzen 9 3900X using two 8GB modules versus four 4GB modules using the exact same memory timings. We found that when using rather slow DDR4-3000 CL16 memory, we were looking at a 3-5% performance uplift for the average frame rate at 1080p using an RTX 2080 Ti, but also gains as high as 10% when looking at the 1% low results.
