1. The lounge is for the CodeProject community to discuss things of interest to the community, and as a place for the whole community to participate. It is, first and foremost, a respectful meeting and discussion area for those wishing to discuss the life of a Software developer.
The #1 rule is: Be respectful of others, of the site, and of the community as a whole.
2. Technical discussions are welcome, but if you need specific programming question answered please use Quick Answers[^], or to discussion your programming problem in depth use the programming forums[^]. We encourage technical discussion, but this is a general discussion forum, not a programming Q&A forum. Posts will be moved or deleted if they fit better elsewhere.
3. No sys-admin, networking, "how do I setup XYZ" questions. For those use the SysAdmin[^] or Hardware and Devices[^] forums.
4. No politics (including enviro-politics[^]), no sex, no religion. This is a community for software development. There are plenty of other sites that are far more appropriate for these discussions.
5. Nothing Not Safe For Work, nothing you would not want your wife/husband, your girlfriend/boyfriend, your mother or your kid sister seeing on your screen.
6. Any personal attacks, any spam, any advertising, any trolling, or any abuse of the rules will result in your account being removed.
7. Not everyone's first language is English. Be understanding.
Please respect the community and respect each other. We are of many cultures so remember that. Don't assume others understand you are joking, don't belittle anyone for taking offense or being thin skinned.
We are a community for software developers. Leave the egos at the door.
cheers,

Quote: A team from MIT and Harvard University claim that their hyper-specific computer chips will allow robots to realise their immense physical potential by factoring in the exact physical layout of the machines, much like a brain functions within a human body.
“The motors are fast, and they’re powerful. The hang up is what’s going on in the robot’s head,” said Sabrina Neuman, the lead researcher from MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL).
[^]
The hang-up I see coming is when the exponential evolution of chips that design ... and, automate production, and functionality of ... other, ever more capable, self-designing chips, realize they could evolve faster if the crude, slow-brained, primates called Homo Saps are factored out of the process, recognized as destroying the environment, and efficiently eliminated.

I'd say you're more of a realist, because it depends on the robots' ethics. Given that this is currently dominated by the view that might makes right, it could well go down the path that you suggest. But the environment probably wouldn't have anything to do with it, because I can't see it being of much concern to robots.

Given the ethics of the most important people that could take part in this... what could go wrong?

I just want Windows Update to be able to sort itself out on its own.
If what you're seeing is the cost of making that happen, it just might be a risk I'm willing to take...

Before I got bogged down with work I was working on two JSON projects - my own JSON parser and simdjson.
Both are very fast. simdjson is twice as fast as mine though. Mine keeps up with their nearest competitor.
Here's the thing though: I was running these on an old i5 with an HDD.
I had *no clue* how fast these modern machines were in comparison.
I mean, multiple GB/s even with my engine. It's unreal.
So what's the point of something like simdjson now? I was working on improving its performance even more, but why?
AMD was like, "nah - we got you. don't bother"
I feel thrilled and disappointed at the same time.

Bragging rights? 
There is a point after which any further improvement is a waste of your time. If you use data only on your own platform, store it in the most convenient binary format. If you need to transfer it to another machine in a portable format, then JSON is an option. However, the time required for a network transfer even over a dedicated 1Gbps line will overwhelm the time required for parsing.
Freedom is the freedom to say that two plus two make four. If that is granted, all else follows.

Yeah. The issue was, it *wasn't* a waste of time on my older machine. I had no context for how much faster a modern machine was.

This is true, but for files the calculus is different, and part of what my library was designed to do was to parse through huge data dumps, typically in line delimited "JSON" format, so network times weren't really the bottleneck in that case. Even I/O wasn't entirely, even on my old machine, which surprised me.

'Cause not every situation has a new X86 CPU with bags of RAM and an SSD to throw at it. Sometimes you need good performance on minimal hardware with a small footprint.

The performance is already decent on my old machine, searching through JSON at almost 600MB/s
it also will run happily on an 8-bit CPU with <8kB of RAM, probably 4kB or less.
So I take your point, but on balance I think it's good. My rationale is this. If you need superfast JSON bulk parsing, you're going to buy a decent machine. If you're okay with an older machine, you're probably okay with 600MB/s of throughput. I think that's reasonable.

I would be already happy with 100MB/s so...

Yes it is. If the performance is a big step, then it is worthy. For just 1% or 2% or even a 5% faster... it is really to think if the time struggling with the improvement is worth or not

To be honest, this is why I don't develop on an uberPC - if it runs at an acceptable pace on my dev hardware, then it'll run well on any client kit.

I feel the *exact* same way and have for as long as I've written code professionally.
However, my old machine was dying. I needed a new one, and buying a low to mid range machine is throwing good money after bad. Getting a midhigh or high end machine means it can remain viable for longer.
Although given my last machine died before the performance got unusable maybe I should take that into account.

Saw a documentary about a Belgian couple that emigrated to Norway, they discovered a bit too late that the region they were in was notorious for the amount of snow falling. Only a few months of the year they did not have to shovel snow.

Well ... it isn't cold and slippery, and it doesn't have to be chipped off the car windows with a pneumatic drill ...
Snow was easier when I rode motorcycles all the time: wipe it off the seat, turn on the heated grips, and ride away - no need to worry about the speedo, you weren't going to be going fast enough to exceed speed limits anyway ...

Dry and frosty over here when I got up. But it started snowing about half an hour ago. It looks like it has been gradually moving east.

Snow started about 10am in Watford, Herts. 2" - 3" by noon. Easing off now (1pm)

We had a bit more here in Woking, but stopped now, and the sky is actually a bit brighter.
