I do recall google apparently stopped using raid in some data centres, but it was because they had whole-machine redundancy.
RAID is probably redundant for some of the uses it used to have, like optimising read performance by using many drives (SSD is fast) and honestly I suspect that SSDs are probably more reliable as they don't have a bunch of platters and bearings and screaming rotational speeds.
So if you needed it for a base level of reliability, an SSD on its own may have exceeded that.
I suspect there are still uses for drive redundancy in some high availability setups.. although your friend might be right. If the likelihood of drive failure is lower than other parts in the machine and you need high redundancy for availability it might make more sense to replicate the whole machine rather than the drives.
It's possible redundancy specifically for the drives was an artifact of unreliable drives back in the day 🤔 they might have a point! I think it's likely still useful at times though.
I'd rather hotswap a drive than set up a new server, even if it's a less likely scenario.
if they knew it was legit why didn't they just say nothing? it's weird Putin is on record saying it won't happen, right before it happened. makes him look stupid.
tbh though I'd be surprised if they genuinely had no idea, how can their intelligence be so much worse in their own country?
it's more, we'll hold up a ceasefire by adding conditions for Israel while thousands of Palestinians are dying of hunger or simply shot. I think the hostages should be returned but that should simply be another negotiation.
Personally I think the hostage release and condemning the initial act are fine but both sides holding up a ceasefire based on those details is terrible. People are dying at a sickening rate.
I work in a company with other people. it's not a good idea to have an idea where you have to specialise in a range of things to be successful. I specialise in programming.
also, those benchmarks translate to better user experience which means they actually use our product, and lower hosting costs.
frameworks and patterns reduce bugs and let us create features quickly. it's important, if you think it's pointless maybe it's not for you. if you want to go do a startup instead, good luck.
