IT departments noticed there are more viable options than VMWare. Thanks Broadcom!

This is an old PC (Intel i7 3770K) with 2 HDDs (16 TB) attached to onboard SATA3 controller, 16 GB RAM and 1 SSD (120 GB). Nothing special. And it’s quite busy because it’s my home server with a VM and containers.

The question is how do you get a bad performance with ZFS?

I just tried to read a large file and it gave me uncached 280 MB/s from two mirrored HDDs.

The fourth run (obviously cached) gave me over 3.8 GB/s.

It’s a well-known problem in the upper management that they only understand Excel.

I’ve seen inventories, statistical calculations, databases, project plans, calendars, address books, password management and even presentation slides done in Excel.

But Germany has no space for nuclear waste. They haven’t been able to bury the last batch for over 30 years. And the one that they buried most recently began to leak radioactivity into ground water.

And… why give Russia more military target opportunities?

There is nothing to refurbish in drives. They are just second hand devices. You can check if they are fine pretty easy and you need to take a look at the age (power on hours). I replace drives at 50k-60k hours, no matter if they are fine.

Mine doesn’t satisfy them, either. I switched off TPM in BIOS.

I laughed a bit. Thanks.

Most of these observations are subjective. I’ve had some Seagate drives that worked well but were very hot and wasted energy. On the other hand WD was crap so far, starting with 3 TB. Not because of quality, but because of power saving features that were a major annoyance to me (green and some blue drives). Red drives I had were mostly fine, even they wore out pretty quickly (Load_Cycle_Count bugs). They ran at 0% health left for a few years and had other awful SMART and on-drive controller bugs.

Since Seagate and WD are essentially the same company and they lied about SMR before, I wouldn’t buy either of them.

In 2020 there have been around 3000 data centers in Germany. Sounds more plausible to me.

Germany only 521? Seems a bit low.

What counts as a “data center”? How many rooms and how many racks does it need to have?

I don’t like the term “clever” in code, because sometimes it means “I’m too dumb to understand it”. Simply don’t touch clever code, unless you really understand it.

Best example is the fast inverse square root function in Quake. Yeah… it’s clever, but replace it by simple maths and let Quake have performance problems.

On the other hand, using AI for more than assisted coding is never clever. Some day some fuck will use it in medicine and will actually kill people. AI is not at fault here! It’s the programmer who killed a patient in this case by being irresponsible and lazy.

Devs care to debug code only if they believe in its quality. Otherwise they write the code again from scratch. This is also cheaper than debugging.

AI code is not clever. It’s all developers averaged. Even if it worked properly, you’d get average quality code.

It’s rather lazy and cheap. This is where the quality is lacking.

Are you looking for something like cached credentials?

Also, lots of nasty bugs are in systems, because of bloat. They are getting fixed slowly, but who doesn’t know cases where you cannot shut down the machine, because of “bouncing stars”.

I still need to look up how to write an own startup script or start two same daemons listening on different IPs. This is why I avoid systemd on servers and only leave it on workstations.

I wish that someone sues when something breaks in the car that you didn’t opt in for.

And… yet better, they get sued when something breaks that is in connection with a paid service and someone suspects that it’s because they paid part caused it.

Many manufacturers offer product sheets. You can also use price comparison websites. They sometimes offer an easy way to look at the specs or even compare them side by side.

Some hard drives are built for 24/7 operation. They have higher MTBF ratings and longer guarantees.

Hard drives are very different. Many of them waste energy, lie in the SMART log or just are weird (spin up and down, lose speed, get incredibly hot etc.)
