2020’s Fastest Raspberry Pi 4 Storage SD / SSD Benchmarks

Raspberry Pi Storage Benchmark 2020

We’ve now received over 20,000 benchmarks at https://pibenchmarks.com/! These are submitted by regular people from all over the world.

In celebration of that milestone as well as the launch of the 8GB Raspberry Pi 4 take a closer look at which device you should choose for your Raspberry Pi 4 as determined by science and measurement!

Disabling SCCM MDM Coexistence Mode (Unofficial Imperfect Workaround)

SCCM MDM Enrollment Registry Key

Microsoft recently added a feature called MDM coexistence into SCCM. Basically this makes SCCM shut off most of it’s functionality when a third party MDM is detected on the machine. You will see errors such as “You don’t have permission to install this software” when coexistence mode is enabled.

This post will outline a way I found to turn SCCM back on (with a caveat).

Telecom Monopoly CenturyLink’s Static IP / Modem / UPS Scam Outlined

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 Xubuntu 18.04 Image Released (Unofficial)

Xubuntu 18.04 Desktop Screenshot

After receiving quite a few requests for a lightweight alternative to the default Ubuntu Desktop environment I have added Xubuntu Desktop to my Raspberry Pi 4 Ubuntu 18.04 LTS preinstalled image builds! The Xubuntu version feels much snappier and more responsive on the Pi. It also uses less overall memory freeing it up to do other things on your Pi.

Raspberry Pi 4/400 Bootloader Firmware Update/Recovery Guide

Raspberry Pi 4

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!

New Trezor Native Ethereum Wallet Beta Guide / Features

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!

Examining the Brave Web Browser / BAT Cryptocurrency Token

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!

My Early Bitcoin ASIC Miners (2013-2014) – Pictures / History

Block Erupter ASIC setup

The most competitive Bitcoin mining operations today consist of entire warehouses of large ASIC miners usually located near sources of renewable energy or power plants selling off excess energy production for cheap. To get seriously involved in the Bitcoin mining space of today will require you to already be quite wealthy and to put up some *serious* cash.

But things were not always this way. I found a bunch of pictures in my photo library of my old mining rigs back from the dawn of Bitcoin ASIC mining and wanted to share them. Let’s go on a journey together back to the year of 2013 and explore what old school Bitcoin mining ASIC hardware looked like, how much it cost, and what we can learn from them today!
