Last week, my QNAP-451-based NAS just hung with all LEDs glowing red. This machine has Intel Celeron J1900 which apparently was released with a quality issue - https://en.wikipedia.org/wiki/Silvermont#Errata

Fortunately there's a temporary fix which involves soldering 100Ω resistor between LPC_CLOCKOUT0 and 3V3 pins.

Another set of devices possibly saved from landfill...

Really cool how OpenWRT has been pushing things continuously upstream. I basically had to add a devicetree definition and provide a build configuration fragment with list of extra packages to include/remove.

Devicetree contains info about device-specific leds, storage (NAND partitions) and even has a way to look up mac addresses for wireless interfaces from nand partitions with wifi calibration data.

Just wrote my first ever bytes of 6502 code in assembly and ran it on Apple //e.

All this with built-in monitor and its miniassembler.

At least on Apple //e you can just enter monitor from basic using CALL -151 and then type ! [enter] to activate the mini-assembler. (No need to activate it by F666G).

And if you want to do it too, but don't have access to one, you can always use MAME/

Daylight savings hack:

• Set alarm to 11:59 (on the device with correct time)
• Find the power cord for your appliance
• Unplug it and wait for 10 seconds
• Plug it back in

pdf-stapler almost works, but:

1. How do I create an empty page?

2. It doesn't seem to be supporting 2-pages into one page?

I can almost achieve the correct ordering with following pdf-stapler command, in case I figure out how to create an empty page:

$ pdf-stapler zip orig.pdf 1-40 original.pdf 79-41 booklet-out.pdf

And workaround for the two-pages to one page is using the system printing dialog and where I can also utilize the "print even/odd pages.

Any clue how to achieve the "print as book" on Fedora nowadays. There used to be pdftk and pdfjam packages, although these have been dropped from Fedora repositories.

One alternative that I have seen is pdf-stapler package which has some of the functionality, but not everything.

My problem: I have a 79 page PDF file that I want to print as book (also, my printer lacks collator, so I would have to print one side at a time and then print other side).

My first ever successful flexible print - 6mm bit holder for my EDC toolkit.

Filament is Black eTPU 95A from eSun and it took around 4 attempts (read: failures), until I just used generic FLEX profile for Prusa Mini printer. Printed straight to the satin powder-coated sheet.

It took close to four years for this one but my patch to port COMFAST CF-E355AC V2 wireless router from ar71xx to ath79 is now complete and supported by next major release of OpenWRT: https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=66d2d037ad40dec2653c7c57946215860352423f

Do you have any Bluetooth enabled "smart" gadgets and you want to get rid of the "vendor" app in your phone?

Then try out @gadgetbridge App - https://gadgetbridge.org/ (available on F-Droid).

I wish I had discovered this earlier.

And here's a small writeup on how to actually achieve that (together with k8s objects): https://plaes.org/technotes/k8s-tips-and-tricks/modified-copy-of-existing-secret-with-eso/

Finally managed to figure out how to create a slightly modified copy of existing secret in k8s using external-secrets operator. In my case I had to add one extra parameter to the end of PostgreSQL connection string inside a secret generated by cnpg.

Had to go through the whole RBAC route by creating Role, ServiceAccount, RoleBinding and then SecretStore with ExternalSecret.
