Maybe companies shouldn't be allowed to spew toxic carcinogens into the atmosphere so that wouldn't matter?

I read the entire article before posting, and that's how I knew that the discrete GPU is sitting in an electrically PCIe 2.0 x4 slot (even though it has an x16 connector on the motherboard) that makes it bandwidth limited at somewhat l

As soon as you're talking about going outside of the CPU core you're in the territory of slow, and going off chip over PCIe is very slow (hundreds of nanoseconds). That's why many apps continue to make heavy use of rdtsc wit

It's a tradeoff between power consumption and the needs of software. Software needs a high resolution time source that reliably ticks along at a constant rate. From a hardware perspective, there is a strong desire to turn off PLLs to

Gaming benchmarks seem like the worst possible way to evaluate / portray this kind of CPU since the GPU is completely throttled by the PCIe 2.0 x4 slot housing it. I'd be really curious to see how something like large parallel co

And this is why kernel developers find userland devs to be misguided so much of the time: thread creation is expensive . Thinking that you're saving resources by destroying "unnecessary" threads is not taking into account t

There are lots of us (your friendly local ISP) that would be happy to help someone out learning this kind of thing. Alas, the expensive part is getting an ASN and network to announce which is approaching a kilobuck per year these days iirc

BGP isn't actually all that complicated. Like virtually all routing protocols it is based on the concept of shortest path first route selection using Dijkstra's algorithm. BGP just defines a way for communicating the announcemen

Yes, but banks tend to have policies and procedures in place where large transactions require multiple parties to review and approve. When those procedures get broken, it's usually a result of fraud and appropriate legal actions can b

The upper limit on decent consumer internet is in the 5-10x ratio for oversubscription. 100x is going to be pretty awful, akin to how Xplornet runs there wireless networks (hint: you don't want to be like Xplornet). On my own FTTH ne

Quite true. However, in the case of FCoE, given the performance issues with the Fibre Channel SANs I worked on a few years ago, tail latency in the fabric was the least of the concerns we ran into. Customers would wonder why their persist

The data center bridging extensions ensure that packets won't get lost due to congestion or flow control. They were created in part because fibre channel over ethernet couldn't handle any packet loss in the fabric.
