Avoid multimode. Unlike singlemode fibre it needs upgrading as speeds increase.

Sadly, my T460s died last week. The failure mode is really odd: the screen works for about 1 minute, then goes bonkers (even in the BIOS). I now have a new-to-me T560 that I can use my stash of spare batteries on. I absolutely love the

No, it's not a lockdown. The province lifted those restrictions on January 31st provided you're vaccinated.

I was physically in the downtown core in Ottawa last week. There are plenty of roads with no lanes open for emergency vehicles. My bank is closed because employees can't get into the parking lots they normally use. One of the restau

No vendor wants to sell raw flash without wear leveling that's exposed to software. It's a significant liability from a warranty perspective, as the manufacturer has to potentially replace the device when the user make a mistake

I don't see those ads. My filter bubble is completely different. Personally, I think it would be beneficial for society if all of us were exposed to information that falls outside of what our individual filter bubble normally shows u

That isn't at all what the article is talking about. It's talking about using battery farms to provide support to the electric grid for transient spikes in demand, a role that is more traditionally served by hydro-electric genera

Honestly, I don't care if I have to pay an extra $5/month or more so that when that rare need to talk to a human comes up. The problem is that the automated system isn't doing the job that the humans did, and there's ze

As I post every so often here on Hacker News, have a look at this ad my elderly father got a couple of years ago just before COVID hit: https://imgur.com/a/Lk85lST . It's a perfectly innocent search by someone lo

It's sad that "at scale" has become synonymous with "without human oversight". It used to be that businesses tried to scale up while providing a level of support for their customers that showed they were valued. A

None of the mainstream DDR DRAM protocols support variable latency, so you effectively have that 100% SLA guarantee. I should qualify that may not be true for some of IBM's mainframe systems. IBM has created DIMMs that communicate wi

Your comments about AMD are not entirely true: AMD officially supports ECC in the Pro variants of their desktop CPUs / APUs. I'm currently using a Ryzen 3800X with ECC memory and EDAC reports that it's working. ASRock lists

Except that anyone using Intel desktop CPUs pretty much can't use ECC thanks to marketing deciding that ECC is a market segmentation feature. The real way to make ECC happen industry wide is for OS vendors like Microsoft to make it a p

Again, going back to the discussions over on RWT: some of the less robust forms of ECC that DRAM manufacturers typically implement can end up amplifying the problem by turning double bit flips into silent multi bit flips which makes the mem

I would suggest that a slightly better firehose analogy is that you're drinking from a firehose that includes multiple streams of good drinking water, urine and poison all combined together. When you drink from that firehose, what do

DDR is typically a bus with more than 1 DIMM slot per channel. LPDDR is typically point to point. Electrically, it's a lot easier to meet signal integrity requirements on a point to point trace than it is to make a multi drop bus wor

If anyone thinks that on-die ECC is a good thing as the manufactuers are touting, please go read the discussions on this topic over in the forums at www.realworldtech.com. The goal of on die ECC is purely to ensure that DRAM manufacturers

I'm always baffled by the United States. Somehow having the government interfere in markets by buying and storing random products like cheese is OK, but addressing inefficiencies in the health care system is forbidden.

This kind of product market segmentation is something that isn't done by technical people. The sales folks think they can extract more revenue from their products by doing this. Once technical decisions are being made by marketing, t

The biggest risk when adding new fibre to existing pole lines is actually during the installation process. When new cables are lashed to communications strand, the 45 pound cable lasher causes the strand to swing back and forth quite signi

Highway vs urban are not equivalent miles. Highways miles are easy and cannot be taken as proof that the cars are truly Full Self Driving capable in all environments.

Lattice seems to be the most cost effective FPGA vendor. I just wish it was cheaper / easier to get boards made for those of us that don't quite have the time to become EEs.

Microsemi has a new SoC that is based off their Polarfire FPGA series and includes a RISC-V core with a smaller FPGA fabric. Unfortunately they're rather expensive like virtually every other FPGA that has 10+Gbps capable SERDES.
