CenturyLink Tower of Shame

I’m really sorry to say that I was excited when I found out CenturyLink offered gigabit 1000 up 1000 down fiber to the home in the neighborhood I just moved into. Dreams of things like having enough upload speed to leave the cloud and operate jamesachambers.com independently in my own home seemed like they could finally be a reality. Dreams were quickly shattered when I realized what kind of incompetence and dishonesty I would be dealing with.

Raspberry Pi 4 Bootloader Firmware Updating / Recovery Guide

January 4, 2020 / 29 Comments / , ,
Raspberry Pi eeprom

All of the previous generations of Raspberry Pi contained all of their firmware on the SD card. Starting with the Raspberry Pi 4 the device actually has onboard upgradable firmware stored on an EEPROM chip separate from your storage. Updating this firmware is very important as one of the first released updates reduces power usage of the Pi by 30% which also reduces how hot it gets.

In this guide I’ll show you how to update the bootloader firmware (no, it’s not apt-get upgrade, it’s a new utility called rpi-eeprom!) and also show you how to make a recovery SD card if your firmware gets corrupted and needs to be reflashed.

Raspberry Pi 4 Ubuntu Server / Desktop 18.04.4 Image (unofficial)

Fine, I'll do it myself

This is a unofficial distribution of Ubuntu Server 18.04.3 for Raspberry Pi 4. It is provided with the purpose of letting us all play with the new Pi 4’s new increased RAM and other capabilities until Ubuntu’s repositories are updated with support for the newest Pi.

Once official support is released through the Ubuntu repositories this project will effectively cease to exist (until, dare I dream, the Pi 5?). The image supports KVM, has support for the Pi 4’s new 3D display driver, and can also be upgraded to a full desktop installation!

Trezor Ethereum Wallet Beta Main Page

The support on Trezor was traditionally just a link to a third party service where you had to log in through the web interface and export your keys every single time. You can’t even see your balance until you do this!

Fortunately true native Ethereum support has arrived for Trezor in the beta! Not only that, but ERC20 token support was also added which has made Trezor now an extremely capable Ethereum hardware wallet. The beta wallet supports all Trezor wallet devices including Trezor One.

In this article we will examine these new features in depth and give a final verdict!

Brave Verified Publisher Wallet

The Brave web browser is a really interesting experiment. For users it offers an out of the box privacy setup that blocks advertising/tracking. The browser’s rendering engine is Chromium based so website loading/rendering/compatibility performance is comparable to Chrome.

In this article we will take a closer look at Brave and the BAT cryptocurrency and discuss.

Wireless Alternative Using Ethernet Over Power – Black Magic?

Ethernet Over Power Wall Rack

Ethernet over powerline tech has existed for a while but traditionally has frankly sucked. It was slow and had issues with reliability.

After decades of improving standards and technology this has changed dramatically and now makes a very cheap and attractive alternative to wireless in many situations. The latest iteration gives a 1200 Mbps connection right over your existing power lines in your house and is designed to work in “noisy” power environments without interruption.

Raspberry Pi 4 USB Boot Config Guide for SSD / Flash Drives

Raspberry Pi 4 with Samsung 950 Pro NVME SSD

The Raspberry Pi 4 is finally here and has a lot of exciting changes. One very major downside is that it doesn’t support true USB booting yet out of the box (like the 3 series did).
The Raspberry Pi foundation states that it is being worked on and will be added back with a future update. No timeline has been given yet for that to happen but they state it’s one of their top priorities.

Most of my projects heavily depend on having good performing storage so sitting and waiting was not an acceptable solution. In this guide I’ll show you a workaround to use USB devices as your rootfs device and use a Micro SD card as bootloader only which gives us full SSD performance after boot!
