Attempt to update XCDRoast. Instructions at http://www.xcdroast.org/manual/dvd.html

`
su -
/usr/lib/xcdroast-0.98/bin
wget ftp://ftp.berlios.de/pub/cdrecord/ProDVD/cdrecord-prodvd-2.01a12-i586-pc-linux-gnu
mv cdrecord-prodvd-2.01a12-i586-pc-linux-gnu cdrecord.prodvd
chmod 755 cdrecord.prodvd
exit

xcdroast not configured for root usage

xcdroast &

You will get a warning message, this confirms that prodvd is installed

SetUp | Options | CDR_SECURITY_KEY
Now get 4.7GB option, but when attempting to write kept getting can’t init drive option, then it would eject DVD?

So I’ve moved to trying GnomeBaker

 su - cd /src/rpm wget http://repo.nrpms.net/gnomebaker/0.5.0/RPMS/gnomebaker-0.5.0-1.1.fc4.nr.i386.rpm rpm -ivh gnomebaker-0.5.0-1.1.fc4.nr.i386.rpm 

There were some dependancies, but I’ve not noted these here.

At the MySQL and Heatwave Summit 2025 today, Readyset announced a new data systems architecture pattern named Readyset QueryPilot . This architecture which can front a MySQL or PostgreSQL database infrastructure, combines the enterprise-grade ProxySQL and Readyset caching with intelligent query monitoring and routing to help support applications scale and produce more predictable results with varied workloads.

More CPUs or Newer CPUs

In a CPU-bound database workload, regardless of price, would you scale-up or scale-new? What if price was the driving factor, would you scale-up or scale-new? I am using as a baseline the first available AWS Graviton2 processor for RDS (r6g).
