This is a quote by Epictetus. He lived from 55-135 AD.
Listening goes beyond verbal communication. Listening to your own body, to your muscles, and making the mind-body connection is one example of listening. Another example is hearing the sounds of nature. Another is watching how people react to what you say.
Listen with two ears in every sense of the word that you can imagine.
I have 4 identical NVMe drives installed in my system.
Ubuntu treats them as one “multipath” device by default. This is not accurate.
I posted something on Ubuntu Forums, but no response at time of writing. (2021-02-18)
Here’s the problem:
lsblk nvme0n1 259:0 0 1.9T 0 disk └─mpatha 253:1 0 1.9T 0 mpath nvme1n1 259:1 0 1.9T 0 disk └─mpatha 253:1 0 1.9T 0 mpath nvme2n1 259:2 0 1.9T 0 disk └─mpatha 253:1 0 1.9T 0 mpath nvme3n1 259:3 0 1.9T 0 disk └─mpatha 253:1 0 1.9T 0 mpath
The fix is relatively simple. It is outlined in some SUSE Documentation.
#/etc/multipath.conf
blacklist {
devnode "^nvme[0-9]"
}
Once the config file has been changed, apply the changes according to the Ubuntu Server Documentation.
sudo systemctl restart multipathd
And all is good!
lsblk nvme0n1 259:0 0 1.9T 0 disk nvme1n1 259:1 0 1.9T 0 disk nvme2n1 259:2 0 1.9T 0 disk nvme3n1 259:3 0 1.9T 0 disk
Beef shoulder roast and beef chuck roast were on sale at Harris Teeter.
The sticker on the shoulder roast package said “oven roast” and the one on the chuck roast package said “pot roast”.
I put the shoulder roast in the oven. It worked out well.
It tastes like the beef that comes in a Chinese restaurant dish. It is relatively tough and relatively lean. Has good strong flavor. Would definitely make again.
It was delicious cut up into strips to make a sandwich!
I tried making hamburgers today. The result tasted like bland meatloaf.
I’ll try again later this week.
Despite the click-bait header, I will not comment on whether the size of a Windows installation is “too” big.
However, I do have facts!
I installed Windows 10 version 20H2 on a VM with no internet connection.
Once I was on the home/welcome/desktop screen, the installation used 18.8 GiB.
After performing Windows updates, and installing VirtIO drivers (to help performance of VM) the total install size was 23.5 GiB.
These results were logged on 2021-02-07.
I want to connect my Dexcom receiver to a computer. This will allow me to track my blood glucose over time. Then, I can identify trends and patters to help improve my insulin dosing.
Dexcom’s software only appears to work for Windows. I only have Mac/Linux/FreeBSD machines at home. I want to pass the USB Dexcom device through to a Windows VM.
For many people and use cases, this seems to work fine!
I was able to pass a USB flash drive through to a Windows VM with no issue.
Things were looking promising after the USB flash drive worked!
They looked even more promising after the Qemu Monitor recognized the Dexcom device.
qm> info usbhost
Bus 1, Addr 15, Port 10, Speed 12 Mb/s
Class 02: USB device 22a3:0047, DexCom Gen4 USB Serial
Unfortunately, the device was not recognized by the Windows Device Manager.
I thought this might be fine, and that the Dexcom software would find the right driver and solve the problem! However, the Dexcom program gave prompts as if the device was not plugged in.
Proxmox has robust documentation on USB passthrough on their wiki.
The basic things I tried were
Sample Commands:
#device info
qm> info usbhost
Bus 1, Addr 15, Port 10, Speed 12 Mb/s
Class 02: USB device 22a3:0047, DexCom Gen4 USB Serial
#by bus and port
device_add usb-host,hostbus=1,hostport=10,id=usb1
device_del usb1
#by vendor and product ID
device_add usb-host,vendorid=0x22a3,productid=0x0047,id=usb1
device_del usb1
I tried in different USB ports, after restarting VM, and other miscellaneous troubleshooting as well.
The results were consistently the same failure.
I borrowed a Windows laptop, and it worked fine!
I’m not sure what the root cause is for this issue. One possibility is that the Vendor ID seems to be in USB device databases on the web, but the product ID is not.
It is possible that Proxmox needs to have a valid/known product ID to pass to the VM.
It is also possible that the Dexcom software is written in a way that just doesn’t work when the USB device is not on the bare-metal machine. After all, the VM does need a virtualized USB hub etc., so it might just inevitably break some code.
Another possibility is that the Windows OS layer isn’t pulling the device details through properly, even though Proxmox is sending all it can.
Who knows! With such a tall software stack, combined with a tiny user base (type 1 diabetics with this particular device who are tech nerds like me) the answer to this question is likely to remain a mystery forever. Oh well.
I’ve never baked a beef rib roast before! Here’s the story of what happened.
Seasoned it with salt, pepper and garlic. Placed on countertop for a few hours. Put into the oven when the roast was 52 degrees.
Baked at 250 degrees for about 3 hours. Once the roast reached 120 degrees, cranked the oven up to high for almost 10 minutes to get a sear.
After searing and removing from the oven, the roast was at around 126 degrees.
The result was pretty good! I was going for medium rare, but ended up at a medium.
For my first-ever attempt: I’ll take it! ????
Next time I’ll endeavor to have it closer to rare. Stay tuned.
Here’s a python script.

Today, Jupiter and Saturn formed a visible “double planet” for the first time in 800 years. It was also the winter solstice.
The winter solstice of 2020 was a once in a lifetime opportunity to see the planets align!
Bethany and I managed to snap a few photos!
Here is the “double planet” that looks like a single one with the naked eye.
Jupiter and Saturn are the bright spot toward the top left of the tree.
With the binoculars, you can see the two planets distinctly. It took both of us together holding the phone camera and binoculars to make this happen ????
What a great relaxation spot!
