I have been working with Docker for years and I didn't know about the lazy loading feature https://engineering.grab.com/docker-lazy-loading #SRE #SysOps #Containers #Docker #Performance

Docker lazy loading at Grab: Accelerating container startup times

Large container images were causing slow cold starts and poor auto-scaling for Grab's data platforms. This post explores how we implemented Docker image lazy loading with Seekable OCI (SOCI) technology, to achieve faster image pulls and startup times. The blog discusses how lazy loading works, the technology behind SOCI and eStargz, and finally how this configuration delivered a 60% improvement in download times.

Sysops note:
Learning happens in the gaps between design and cock-ups.
Root disk filled, Postgres did the right thing and refused to start, backups proved their worth, DB moved onto its own volume, system calmer than before.
Architecture improves fastest when reality gets a vote.

W ciągu ostatnich 3 miesięcy zdałem #AWS-owe trio certyfikatów Cloud Associate, czyli #Developer, #SysOps oraz #SolutionArchitect. Zacząłem od SAA. Najtrudniejszym był #SAA, jego pytania były najdłuższe i najbardziej wymagały zastanowienia, natomiast najprostszym był #DVA - ten jest na kompletnie niższym poziomie zaawansowania (nie licząc pewnych wyjątków). #SOA to w zasadzie trochę taki SAA, ale z krótszymi pytaniami i bardziej skupiający się na korzystaniu z AWS-a niż na migracjach.

How active you’re in your #career planning? Do you go after what’s needed in your company or following own idea? Or maybe data mining to get best grasp?

I’ve got different background in IT and outside (PM, ScrumMaster, App Admin). Over the years I decided to dive into technical aspects. This landed me over time as senior staff but then realization came that I’m missing some critical parts. Did AWS DevOps - company wasn’t looking to utilize this. Potential new one were looking for experience not just training. Dead loop. Recently was working on #kuberneres deployment on #rancher this kicked me to get #CKA
what old school #SysOps are learning?

TIL: If permissions of a pam.d file does not allow reading for a program it's ignored and any unix account is accepted. No logging about that whatsoever. Insane!

As our company hosts servers, we have a public Security Policy and a security.txt file for ethical hackers to disclose vulnerabilities responsibly: https://handbook.dude.fi/security-policy

Because of this, I receive quite a few reports, most of them ineligible. I've also run into some "security experts" getting upset about not receiving a bounty for a non-issue or putting heavy pressure on payments for valid ones. It often feels unfair, like I'm being held hostage.

That's why replies like the one I just received warm my heart so much:

"Thank you very much for the clarification and for taking quick action to remove the DNS record. I appreciate the transparency and the kind offer as well.

I'd prefer to donate the amount to a child support charity instead. You’re very welcome to donate it on my behalf to any such organization of your choice."

Donation made. Thank you, stranger. Kindness costs nothing.

The #FediVerse difference in a nutshell, I think: relatable interruptions and problems in life.

We don't have service interruptions because some nutter decided to spend millions of quid on some snake oil or playing at politics in a foreign country.

We have service interruptions because the sysop happened to be in the middle of cooking dinner. Or was in IKEA. (-:

And the rest of the world does not fall apart.

It's the BBS days all over again, where we actually know our #sysops as people, which isn't a bad thing.

Why rsync from HDD to SSD is slower than from SSD to HDD?

To be exact, ~60-100MB/s HDD -> SSD, pretty stable 120MB/s SSD->HDD

I'm talking 460GB of small files (photos and videos) so I don't believe cache/buffering is significant here no?
