 Hi all,

I guess it's time for another food for thought email of like-minded
FreeBSDers, as I am coming to a new conclusion about this whole enterprise
crap world of which I am so evermore fed up of...

For me it all started with a comment about Theo de Raadt's visionary
comment here, brought to light by Ian Smith in 2017:

https://docs.freebsd.org/cgi/getmsg.cgi?fetch=3D117621+0+archive/2017/freeb=
sd-questions/20170820.freebsd-questions

At the time I was going through Java / AWS hell so I posted this rant which
was followed up by interesting and diverse commentary:

https://groups.google.com/forum/#!topic/ml-freebsd-questions/bMlBTj4Xx_Q

And now I have been recently exposed to the pinnacle of enterprise crap:
microservices.

Not saying that they are not a good idea, on the contrary, they are! But is
this all really that new??

So modern-day microservices rely heavily on virtualization (Linux on AWS),
pseudo-virtualization (Docker), and well, the microservices themselves.

They bring on a whole new set of challenges such as log unification
(usually through something like Elastic Search, Log Stash, Kibana, Beats,
etc.), and IPC (through an MQ su as Apache Kafka). Plus a whole new pile of
shit that they are throwing at this microservices "architectures" such as
Hystrix and of course, everyone needs to be "streaming" so they throw in
stuff like Spring Reactor or RxJava, "new" Actor design patterns like Akka
(actually invented in 1973) and well, whatever other thing that Netflix or
Amazon use, then everyone else has got to use them too.

Read any book on the subject and well, cry. Talk about layers and layers,
upon layers and layers of crap, basically to achieve something like, well:
Unix, TCP/IP and HTTP.

So let me breakdown a few of these things so you get what I'm saying:

Reactive Streams: a new FAD designed to handle "back pressure" and vertical
scaling by taking advantage of multi-core CPU's and low-level caching
issues etc. Well, guess what, enterprise idiots: that's EXACTY why you want
a solid Operating System that sits on, and it's fined tuned to that
specific real hardware! and with regards to back-pressure, old school
protocols such as HTTP have had things like 503 and RetryAfter header from
their original design!!

It's so funny that most of these things are for multi-core optimizations
that are not even running on real hardware!

Log Unification: well how about a little education on RFC 3164 and Log
Analyzer?

Virtualization: isn't this what Unix basically is? I mean the concept of
processes that are running and sharing resources is that not virtualization
by principle?

Pseudo-Virtuzalization: Isn't this what chroot and BSD Jails do? Oh you
want an easy interface like Docker, well how about EzJail?

IPC: Isn't that what pipes and SYS 5 IPC provide: an MQ, Shared Mem and
Semaphores? Oh too slow? (really? compared to what?).

And finally the crown jewel: microservices. Well, isn't this one of the
basic design principles of Unix? I mean tiny little things that talk well
to each other to build big things with?

Honestly I could go on but I thing you get the idea. It seems that this
whole "enterprise" industry has been hell-bent on re-inventing a big, bad,
ugly and expensive version of Unix, just because they don't want to tie
their design to Unix? For portability? to what?, well to another flavour of
Unix called Linux, running on Xen and well, Linux.

Is there are real proof that all this microservices crap is really that
much better than individual processes (e.g. built with sh, Perl and/or C)
running on a fined-tuned Unix system on real hardware?

Oh yeah, that's right, high-level guys are too expensive? really? compared
to what? to the dozens and dozens of mediocre "coders", "devops",
"techops"and whatever other "ops". Yeah, we are way more expensive but we
are 50:1, maybe 100:1 compared the median in the "enterprise" side of
things.

Steve Jobs was so right about the "dynamic range"of A players:
https://www.youtube.com/watch?v=3D7yh7ikSQwKg

Anyway, that's my rant of the year ;-)

Thanks so much for FreeBSD!!

I have a new HP Slimline Desktop 290-p0014 which features an Intel i7-8700.

I can install two instances of FreeBSD 11.2 Release, here's the boot process documented in eufi man page:

3.	/boot1.efi/  searches partitions of type freebsd-ufs and
		freebsd-zfs for	/loader.efi/.  The search	begins with partitions
		on the device from which/boot1.efi/  was loaded, and continues
		with other available partitions.  If both freebsd-ufs and
		freebsd-zfs partitions exist on	the same device	the
		freebsd-zfs partition is preferred./boot1.efi/  then loads and
		executes/loader.efi/.
	   4.	/loader.efi/  loads and boots the kernel, as described in
		loader(8)  <https://www.freebsd.org/cgi/man.cgi?query=loader&sektion=8&apropos=0&manpath=FreeBSD+11.2-RELEASE+and+Ports>.

The result is that a second freebsd partition can never be booted.  I have always liked to install a second instance of freebsd to use as a recovery drive, rather than waiting for a slow CD-ROM boot.
When I installed two instances of FreeBSD, bsdinstall added two lines in the BIOS boot menu (I pressed F9).
But both lines are identical:
UEFI OS (TOSHIBA HDWE160)
One I gave the hostname Chameleon and the other was Recovery.  I also labeled each partition that way.

Is anyone working on enhancing boot1.efi to support booting from other partitions?

I want the functionality of boot0 where FreeBSD displayed all the available partitions and allowed me to select any one.

I can do that now on my machine, but I have to use legacy BIOS boot to an MBR, rather than UEFI boot to a GPT partition.
