Linux 4.15 Becomes Slowest Release Since 2011

An anonymous reader shares a report: Linus Torvalds has decided that Linux 4.15 needs a ninth release candidate, making it the first kernel release to need that much work since 2011. Torvalds flagged up the possibility of an extra release candidate last week, with the caveat that “it obviously requires this upcoming week to not come with any huge surprises” after “all the Meltdown and Spectre hoopla” made his job rather more complicated in recent weeks. Fast-forward another week and Torvalds has announced “I really really wanted to just release 4.15 today, but things haven’t calmed down enough for me to feel comfy about it.”

Migrating MySQL to PostgreSQL with minimal downtime

When I started writing pg_chameleon I had in mind a tool making simple to migrate from different dbms engines to PostgreSQL.The name was inspired by the Culture Club’s Karma chameleon song which suggested me the idea of a tool capable to move data between different database technologies.Then tool’s scope changed becoming a replica system rather a migration system but I’ve kept the name as I think the idea is still valid. However, during the development of the now discontinued version 1 I needed to migrate a MySQL database rather replicating it. Therefore I added a command to detach the replica, allowing the migration to happen with very minimal downtime.
Prerequisites

pg_chameleon requires python to be at least 3.3; in this example we’ll use python 3.6.The the tables during the initial copy are locked one by one.
So, probably, the best way to setup the MySQL-PostgreSQL replica is to use a cascading MySQL as

Linus Torvalds declares Intel fix for Meltdown/Spectre ‘complete and utter garbage’

 The always outspoken Linus Torvalds, best known for his continuing work on the innermost code of Linux systems, has harsh words to say and accusations to level against Intel. His evaluation of Intel’s latest proposed fix for the Meltdown/Spectre issue: “the patches are COMPLETE AND UTTER GARBAGE.” Read More

Linus Torvalds Calls Intel Patches ‘Complete and Utter Garbage’

An anonymous reader writes:
On the Linux Kernel Mailing List, Linus Torvalds ended up responding to a long-time kernel developer (and former Intel engineer) who’d been describing a new microcode feature addressing Indirect Branch Restricted Speculation “where a future CPU will advertise ‘I am able to be not broken’ and then you have to set the IBRS bit once at boot time to *ask* it not to be broken.”
Linus calls it “very much part of the whole ‘this is complete garbage’ issue. The whole IBRS_ALL feature to me very clearly says ‘Intel is not serious about this, we’ll have a ugly hack that will be so expensive that we don’t want to enable it by default, because that would look bad in benchmarks’. So instead they try to push the garbage down to us. And they are doing it entirely wrong, even from a technical standpoint. I’m sure there is
