lisplist commented on XDP for game programmers   mas-bandwidth.com/xdp-for... · Posted by u/gafferongames

I've actually written a high-performance metaverse client, one that can usefully pull half a gigabit per second and more from the Internet. So I get to see this happening. I'm looking at a highly detailed area right now, from the air, and traffic peaked around 200Mb/s. This XDP thing seems to address the wrong problem.

Actual traffic for a metaverse is mostly bulk content download. Highly interactive traffic over UDP is maybe 1MB/second, including voice. You're mostly sending positions and orientations for moving objects. Latency matters for that, but an extra few hundred microseconds won't hurt. The rest is large file transfers. Those may be from totally different servers than the ones that talk interactive UDP. There's probably a CDN involved, and you're talking to caches. Latency doesn't matter that much, but big-block bandwidth does.

Practical problems include data caps. If you go driving around a big metaverse, you can easily pull 200GB/hour from the asset servers. Don't try this on "AT&T Unlimited Extra® EL". Check your data plan.

The last thing you want is game-specific code in the kernel. That creates a whole new attack surface.

What is a metaverse client? Do you just mean a cross platform VR app?

A buddy works at IBM and told me one of the “perks” is you can earn “Blue Points” that you can spend in some wacky internal marketplace. He got me a DVD of Carrot Top’s magnum opus “Chairman of the Board”

IBM: move near an office and come in three days a week, or tender your resignation and forfeit all of your Chuck E Cheese tickets!!

There’s some pretty nice stuff you can get. Vacation packages as well. Just takes forever to earn enough to do anything useful with.

Doesn't "X is rich but people from X are poor and angry" apply to other countries, like the US for example?

But more importantly the lede to this article is "Germany’s grossly unequal distribution of wealth is contributing to the country’s malaise." but Bloomberg is a journal that aggressively argues for and supports this exact situation in the US?

That's some awe inspiring hypocrisy.

Tbf there are some (mostly rich) people that believe wealth inequality isn’t a problem as long as the standard of living keeps going up for everyone. But that falls apart once you consider monopolization generally leads to rent seeking and not better services

Yes, I’m not sure why but the link got swapped out when I posted the story

How did their 401k match work?
lisplist · 2 years ago
They used to wait until end of year to match funds until recently they switched to monthly matching. So if you left before end of year, your match didn’t pay out iirc. Now they’re getting rid of 401k matching entirely so suppose it’s a moot point.

Pension funds are carefully regulated and cannot be in risky investments. IBM cannot invest in IBM, they have to invest in various bonds. Before pension regulations a few pensions invested in the.company and employees discovered that was a bad idea when the company went bankrupt just before they were set to retire and their pension value went to zero.

I'm not sure if this is legally a pension, if not assume it is worth nothing. If it is the US government backs it and so if you work for IBM for 30 it is a great deal, pensions are defined income so you don't have to worry about if you will live to 66 or 120. (If like most you switch jobs it is terrible)

Legally, I believe this is a pension fund. Still, they have to be pocketing the difference somewhere because why else would they make such a controversial decision that also increases administrative overhead?

In 3 years, if IBMs fund is paying 3%, your HYSA is going to be the same or less. HYSA's are just a treasury fund minus a few bips

Fair, just giving a point of reference
