Making Bluetooth work on RPi4

· Hardware, Linux, Software

I rarely use Bluetooth on my RPis. I'm already facing enough issues with my iMac and Mac Mini (it lags, it randomly disconnects in meetings, etc).

My pwnagotchi on the other hand is counting on a BLE network to connect to the internet: for now I am using my iPad, and while that works, it causes my iPad to disconnect from WiFi (because of course, it can only do tethering from a mobile network, not from its WiFi network).

Beyond Beef Lasagna

· Misc

The last (and only time) I posted a recipe here, was 7 years ago. Wow.

As we're trying to eat less meat in general, we've (Shan and I) been experimenting with vegetarian dishes.

This lasagna has been eaten by a few people now and every time the reviews are pretty damn good. :) It comes rather close to the original taste while being entirely vegetarian.

First off -- we're mostly just swapping out the regular minced pork/beef mix with Beyond Meat. There are other brands out there (i.e.: Omnimeat), each with their own taste -- try to see what works for you.

Ideal travel router: GL-AR750S

· Hardware, Linux, Networking, Software

Right. With the pandemic and all none of us are going to travel much but still...

About a year ago I purchased myself an OpenWRT router to use on the plane and in hotels.

And so far I really like both the device and the Hong Kong based brand (launching new and updated products, and releasing relatively regular updates for older products). Pick a device that fits your needs (USB powered? LTE? Small form factor?).

Raspberry Pi 4 + SSD

· Hardware, Linux, Software

All right. With the release of the new RPi4 with 8Gb of RAM I had to get myself one to see if it was already a viable desktop replacement for surfing and emails.

While a SD card works fine for certain tasks (things that don't require a lot of IO) -- for a desktop that's a no-go... It's just too slow.

I still had an old Macbook Pro 13" (2o15?) SSD lying around that was collecting dust. Why not use that one to use as root for the RPi?

iPad Pro USB-C Ethernet

· Apple, Networking

I’ve had an iPad Pro with the new Magic Keyboard and one of the things I've been wondering... Say I am stuck in a datacenter and I need to ssh through wired networking to a server -- sure I'll definitely rather use my Mac laptop, but just in case... But would it actually work?

The answer is... Yes -- but...

Synology "Operation Failed" manually updating package

· Hardware, Linux, Software

Resilio Sync released an update last week and on Synology these package don't auto update. Time to manually update the packages again.

On my DS1515 (more RAM, more CPU) the manual update goes by fine (stop service, manual update, browse for file, upload, start service) but my DS216j, not so much.

Attempting to upload the file instantly fails with the useful error "Operation Failed".

0x04

· Misc, Networking

Almost 10 years after I registered 0x04.com, it's time to part ways.

0x04.com whois
old whois info -- created 29 Aug 2010.

Yesterday I finalised the sale of 0x04.com.

My company in Singapore was called 0x04 pte. ltd. and to avoid any confusion I've renamed to su1 pte. ltd. su1 standing for Superuser.one. 🤷‍♂️

NextDNS, EdgeOS and device names

· Linux, Networking, Software

Noticed that NextDNS was reporting old hostnames in the logs. For example old device names (devices that changed hostnames), devices that were definitely no longer on the network, or IPs that were matched to the wrong hostnames.

The culprit is how EdgeOS deals with its hosts file. Basically it just keeps all the old hosts added and just adds a new line at the end of the file.

Air purifier

· Hardware, Misc

I live in Singapore. And haze is a thing. Thanks Indonesia and burning rain forests to create palm plantations. Needless to say, so far 2019 and 2020 haven't been great.

Anyhow I got myself a Novita air purifier ~2 years ago, and I stole received a Xiaomi purifier from Liyun.
