I made the same error as you, before realizing that in this molecule the fluorine is bounded to a carbon not an oxygen. Fluorine once bounded to a carbon won't move from there unless it receive a lot's of energy. A fluorine bounded to an oxygen really wants to be elsewhere and it's ready to pay a lot's of energy to make it happen! So the scary looking part of that chemical is incredibly stable and this is what make this substance potentially dangerous.

Creatine is dosed in grams not milligrams, otherwise your number are correct.

You are underestimating how much co2 is released during ciment production and overestimating what is released by powering datancenters.

In 2024, datancenter have consumed 1% of the total worldwide electricity production and are responsible for 0.5% of the co2 emissions.¹

Ruining concrete seems to go against extinction rebellion main goal. According to the World Economic Forum the co2 released during ciment production account for 8% of global co2 emissions, datancenter are estimated to contribute between 1 and 2 percent....

Math is not theirs forte!

I disagree, SQLite is a production embedded database, the extensive test¹ suite is a testament to that. It's just has different default and behavior than a database designed for being served to multiples simultaneous writers.

I would choose promox or ovirt (oracle virtualiztion manager is pretty nice, I use it because the licence of the only oracle database of our institution requires it, that and a specialc cores pinning configuration, to avoid licensing every cores in all clusters, https://houseofbrick.com/wp-content/uploads/2015/03/Oracle-P... ) but it's oracle so we went with proxmox.

The FC multipathing was a learning experience and the manual workload placement requires good metrics on your workloads. The built-in ceph is decently configured and more performant than FC if you have 100GBS mellanox NICs and adequate quantity of ram. Veeam integration is serviceable but it's not as mature and polished as the integration available on vmware.

Having tried azure local before (it seems magical but the more you use it the worst it gets, update failed for no apparent reason on only some supposedlyidentical nodes, the sdn was atrocious to deploy and was manageable from wac only), I would recommend proxmox over it anyday.

If you don't have linux expertise on hand and have traditional FC based storage, I would recommend something else, probably nutanix if your budget is big enough.

I wish I knew ... at least it was a span volume so we could use proxmox support for vmdk and achieve about 30 minutes of planned downtime but a week of storage vmotion followed by another week of the proxmox equivalent.

When I get back to work I will finish the samba configuration of the ceph cluster front-ends to replace those elephants.

Before my vacation we (3 colleagues and myself) completedan 8 months long migration (coordination with stakeholders is longer and more complex than migrating a 192TB VM !!!) to 6 proxmox clusters so 20 to 40 clusters for 40k is certainly possible but imo it would be unwieldy.

Could you give a recent example? Because your example is as pertinent as the overthrowing of Guatemala's democratically elected President in 1954 by the CIA.

Proxmox for 40k vm would be surprising also veeam support Proxmox.

There are 2 maple grove owner in my extended family (both are my uncles one on my father side and one on my mother side) so I never saw that as a luxury product and never had to acquire maple syrup at market price.

But I understand your point, if you grew on the fake stuff and considering how expensive maple syrup is, you have nothing to gain by training yourself to prefer the real stuff.

I predict that they will be as effective as Extinction Rebellion : lot's of noise, some protesters arrested and no results.

What's the grade of the maple syrup you tried ? (the new grading system is stupid everything is grade A with a color name)

In my opinion,

The A golden is light and subtle, I don't know what it's for; it's the variety we sell in tourists, and to peoples that likes fancy bottles and higher prices!

The A amber is great as a condiment in small quantities, for pancakes it's the best.

The A dark is the best for cooking deserts.

And the A very dark is my favorite for cooking meats like ham and ribs.

So if you only tasted the A golden I can see why you would prefer the fake syrup if you were raised on that stuff. But I would be surprised if you prefer the fake stuff to the A dark.

You could launch it as a systemd user target with OOMScoreAdjust=500 in the service section; weird and unconventional but wrapped in .desktop file it doesn't appear to be unwieldy.

It's a Rust/ASM port, look there: https://github.com/memorysafety/rav1d/blob/main/src/ext/x86/...

I am not sure if it is that much safer than the C version when raw assembly is still required.
