I recently received a 13″ MacBook Pro with an internal 512GB SSD. I support a lot of different products and need to virtualize many different environments to do so. Naturally, 512GB fills up pretty fast when creating a bunch of virtual machines so I started shopping for decent external SSDs. It seems silly to waste my money on SSDs based on USB 3.x interfaces as they generally top out between 500MB/s to 1050MB/s when we now have Thunderbolt 3 which is 4 times faster at 40Gbps.
The Sticker shock of these new TB3 SSDs is a bit much as at the time I’m writing this, the Samsung X5 2TB SSD is a whopping $699.99. I just couldn’t justify this purchase and started doing a bit of research. Turns out you can buy the enclosure and an M.2 2280 SSD and save yourself over $300. I just booked the order at Amazon and will update this when the parts arrive and I’ve put it together and tested.
Here are the parts for reference and calculated savings:
I’ve recently been evaluating iSCSI target drivers on my Mac. I tried several and I won’t bore you with those details but one, iSCSI Initiator X from KernSafe, did cause some issues following the evaluation. I wanted to capture the steps I needed to follow when I noticed severe performance issues following my evaluation period.
I am providing support for Solaris Cluster again and have am now on a Mac (Hacintosh) using Vmware Fusion for my virtualization. Before you proceed with this tutorial, you must first install socat on the Mac as it is used to perform the console I/O redirection. I suggest using homebrew:
Here’s a quick bash script to clean up archive logs older than a week. It reads the Oracle SIDs from /etc/oratab and invokes rman for each SID. One could put this in cron to be run once a day to keep disk space usage in check.
I recently had the need to install systemtap on one of my CentOS 7 VMs and the process isn’t as straight forward as it should be. It seems not all packages needed are built for all revisions of the kernel. After much searching, I managed to get this working and wanted to archive this procedure.
I wanted to capture the changes which need to be done to a fresh centos7 server install to support Oracle 12C. The server was installed with Basic Server using a 4GB swap device but before we can start the Oracle install, we need to prepare the system.
Preheat oven to 350 F. Prepare pan (a 10×15 pan with sides works best) with oiled parchment paper or a silicone mat.
Mix dry ingredients well – a whisk works well.
Add wet to dry, and combine well. Make sure there aren’t obvious strings of egg white hanging out in the batter.
Let batter set for 2 to 3 minutes to thicken up some (leave it too long and it gets past the point where it’s easy to spread.)
Pour batter onto pan. Because it’s going to tend to mound in the middle, you’ll get a more even thickness if you spread it away from the center somewhat, in roughly a rectangle an inch or two from the sides of the pan (you can go all the way to the edge, but it will be thinner).
Bake for about 20 minutes, until it springs back when you touch the top and/or is visibly browning even more than flax already is.
Cool and cut into whatever size slices you want. You don’t need a sharp knife; I usually just cut it with a spatula.
