Ditched Roku for a Discounted Origimagic Ryzen 5 Mini PC
I’ve been unhappy with Roku’s increasing advertising through images and now full-motion video and their lack of support for a variety of codecs in their media player app. So, I’ve been looking for awhile for a good deal on a mini pc that could replace the Roku for playing media and also support some light gaming. Also, considering the impending tariffs (i.e., a tax on Americans), I hoped to find something as soon as possible.

After tracking several mini pcs on Amazon and eBay for a few weeks, I finally pulled the trigger when Amazon offered the Origimagic C4 Mini PC with a Ryzen 5 3550H (4 core, 8 threads) on sale for $153. It’s CPU has a lot more horsepower while using 25 watts of power than Intel’s similarly priced mini pc processors. It came stock with 16GB DDR4 RAM, 512GB PCIe SSD, 1 x Type-C USB, 4 x Type-A USB (3 are USB 3 and 1 is USB 2), headphone jack, HDMI, DisplayPort, and dual ethernet.

To operate it from the sofa, I got a $10 reiie H9+ Mini Keyboard with Touchpad that uses a wireless USB adapter to connect to the mini pc.

Before setting anything up, I created a flash drive with Debian 13 Trixie, the latest version that was released over the weekend on Saturday.

To do this, I inserted a 16GB flash drive into my workstation, but I didn’t mount the device. I downloaded the network install ISO for Debian 13 from here. Then, I ran lsblk in a terminal window to see what device address corresponded to the flash drive. It’s important to not make a mistake here, because it’s easy to overwrite another drive using this method. lsblk lists the devices, which are all in the “/dev/” folder, so when I saw that my flash drive was assigned the address “sdb”, I knew that its full address was “/dev/sdb”. With that info, I then wrote the downloaded Debian 13 netinstall ISO directly to the flash drive using this command:
```
sudo cp debian-13.0.0-amd64-netinst.iso /dev/sdb
```
After the copying to the flash drive had finished, I ejected it from my workstation and took it over to the mini pc. I plugged in the power adapter, ethernet cable (I arbitrarily picked the one furthest from the power plug), HDMI cable to the TV, the keyboard receiver USB, and the Debian 13 installation flash drive.

I did experience some frustration with getting the Debian 13 flash drive to boot the mini pc. As soon as the mini pc booted, I was unable to enter BIOS or open the boot menu. Instead, it kept booting into the Windows 11 setup, which I did not want to use. At first, I thought it might be a problem with the tiny wireless keyboard and trackpad, so I switched to my Logitech keyboard and trackball, which are both tied to one Logitech USB receiver. I tried different USB plugs on the front and rear of the mini pc until I was finally able to enter bios (pushing DEL at boot) when the keyboard USB receiver is in the top-right USB port on the rear of the mini pc as shown below (it is a USB3 port). It might have been bad luck on my part with the other ports, so I can’t say this is a peculiarity with this hardware for certain. Nevertheless, it’s good to exhaust all possibilities like this.

Once in the BIOS, there’s not many options except for disabling hardware (I disabled WiFi), turning off Secure Boot and the Trusted Computing Module, and other odds and ends. I saved the settings, rebooted, and went into the Boot Menu (F7), selected the Debian 13 netinstall flash drive, and began the installation (a full nuke-and-pave: erasing the NVMe drive and setting up Debian 13 as the only operating system).

While I use XFCE on my laptop and workstation, I opted for the GNOME desktop environment on the mini pc, because I thought its screen controls and overall user interface would be easier to see and navigate from across the room. If I don’t like it, I can always install XFCE.

Because two of the main sources of media for us is Netflix and YouTube, I installed Chrome to handle those sites. I have VLC and Kodi for everything else.

“We Will Always Be Here,” A Transgender Pride Flag in Brooklyn

Walking down 3rd Avenue in Brooklyn yesterday, I saw that someone had added something to a larger graffiti: a small transgender flag and the words: “We Will Always Be Here.”

As I’ve posted before, trans rights are human rights.

If you actually believe in freedom and individual rights, you believe in rights for everyone.

Put another way and borrowing a metaphor from JFK, guaranteeing personal freedoms and rights for the least advantaged is like a rising tide that lifts all boats.

Rights are not a zero-sum game. Ensuring rights and freedoms for more people supports everyone’s rights and freedoms. When you advocate for taking away rights and freedoms from one group, that’s fascistic. Ultimately, taking away others’ rights erode and likely lead to erasure of your own.

The hysteria over trans persons manufactured by the right is not so much about an infinitesimal minority’s rights to life, liberty, and the pursuit of happiness. It’s an attempt to erase a group of people from public space and social participation. It’s one beachhead in a multi-headed attack on foundational American ideals.

These attacks are also anti-scientific regarding the reality of both sex and gender. Ignoring transgendered persons about their lived experience and the deep and vast knowledge from biological, psychological, sociological, historical, and legal experts focusing on transgender issues is obviously guided by bigotry and willful ignorance.

For those folks who want to be allies and want to learn more, I highly recommend Dr. Susan Stryker’s Transgender History: The Roots of Today’s Revolution (Revised Edition, 2017). Her website is also an invaluable resource, including links to her other work, such as the foundational (and free) essay “My Words to Victor Frankenstein Above the Village of Chamounix: Performing Transgender Rage” (GLQ, 1994).

Crank-Style Telephone at Cracker Barrel in Waycross, Georgia

A few weeks ago, I saw this crank-style telephone hanging on the wall to the left of the fireplace in the Cracker Barrel Restaurant in Waycross, Georgia. It’s plaque on the front says, “Chicago Telephone Supply Company Elkhart, Indiana, U.S.A.” I didn’t think to try turning the crank handle on the right side to see if the dynamo was still installed. Also, the top box seems to be missing the locking mechanism (just the hole is seen on the left under the ringer).

There is some dissonance viewing the phone from this angle, because you can see the flat screen computer monitors used by the restaurant employees in the alcove on the left.

Mr. Toad Waits

When I moved a pile of oak boards (that had been there at least a decade) off my parents’ porch a few weeks ago, this toad hopped out from underneath them. While I was finishing up, he moved over to this 1″ x 4″ board in front of the patio door. I took this photo, because it looked like he was waiting to be served at his local.

Old City Hall and New Murals Around Brunswick, Georgia

When my dad and I stopped at Tait’s Feed and Seed a few weeks ago, I walked around and took some photos of the Old City Hall and some street art murals in and around downtown Brunswick, Georgia.
