Benchmark Storage Performance on Linux

Linux Storage Benchmark

When attempting to determine storage performance on Linux there are common tests such as doing a DD write command and measuring the speed of that. These methods leave a lot to be desired and are especially bad at measuring random read/write performance (the most important for operating system / application performance).

I solved this problem for the Raspberry Pi by creating Pi Benchmarks. This is an open source benchmark that *does* measure random read/write performance as well as several other important factors (IOPS, etc.). We’ve collected many years worth of performance data across thousands of different drives including SSDs / HDDs / others. It’s enough information to be used to make important decisions about performance using hard data.

I’d like to announce that this exact same benchmark is now available for all devices! If you’d previously taken the benchmark on a PC or device other than a Raspberry Pi those results are now retroactively live on the site.

Raspberry Pi Shortage Survival Guide

rpilocator - Raspberry Pi Stock Locator Tool

The Raspberry Pi shortage is extremely bad. As a site that covers a lot of topics related to the Raspberry Pi I’ve actually seen a major decline in traffic because people are having such a hard time getting these.

Stock on Amazon is limited and it’s being scalped with prices such as $99 for a Zero 2 W and $187 for a Pi 4 8GB. Those are absurd prices.

There are some Pis that are smarter to buy right now than others that you may not be thinking about. Today I’d like to cover additional places to get your Raspberry Pis during the shortage as well as recommend an alternative Pi (a more powerful one actually) you may not necessarily be thinking of!

Legendary Minecraft Bedrock Container

Minecraft Bedrock Docker Edition

I’ve been getting asked to put this together for years including in official GitHub issues. I always knew it would be a great idea but it turned out even better than I expected. This image works great on all platforms including Raspberry Pi!

This is based off my Minecraft Bedrock Linux Dedicated Server scripts for Linux project. I’m going to release a version for the Java Minecraft edition as well so stay tuned for that.

Best Altcoin Mining Pools / Exchanges

DxPool

For quite some time now Kadena (KDA) has been topping the charts for mining profitability. There are many other altcoins though that are power efficient to mine such as Starcoin (STC) and Siacoin (SC) and many others.

The only problem with these coins is that they can be difficult to find good pools and exchanges that will accept them. Fortunately if you know the right places to go you can essentially take care of *all* of your altcoin needs with just a couple of pools and a single exchange.

Today I’ll cover where I do all of my altcoin mining and where I exchange those tokens with minimal fees. Let’s get started!

Benchmark Tinker Board, ODROID, Pine64, OrangePi and others

PiBenchmarks.com - Benchmark #43289

PiBenchmarks.com is now several years old. It has over 31,000 identified benchmarks. Previously only results from the Raspberry Pi would show live on the site.

like to announce that over the past couple of weeks I’ve added support for the SBCs that many of you had already submitted benchmarks for (even though they weren’t recognized on the site yet). These are now all retroactively live on the site right with all of the Pi submitted benchmarks.

Let’s take a look at a list of some of the models that were added and how to run the benchmark!

2022 – The Year of the Linux Desktop

Year of the Linux Desktop

It has been a long-running meme in the Linux community that each new year would be the “Year of the Linux Desktop” for decades now. This never happened. Why? A big reason is compatibility with gaming. Some titles worked on Linux but not very many of them.

ibility options they developed for the Steam Deck called “Steam Play”. Virtually every title I own in Steam plays flawlessly on Linux now as these options are available for all Steam Linux users and do not require owning a Steam deck to take advantage of.

Today let’s explore the things that have changed that up until this point had been preventing the year of the Linux desktop!

Why GPU / Ethereum Mining Is Toast – Stop Buying GPUs

whattomine.com

One way I keep up with the developments in cryptocurrency is I do watch some of the YouTubers since the YouTubers are generally following the juiciest developments to farm views. With the continued news that Ethereum is going to launch Eth 2.0 and is more or less on time (now called the “Ethereum consensus layer”, how catchy) how much denial there is around this fact.

Except we are way past that point now. It’s literally these YouTuber’s job to know that GPU mining is toast and today I’m going to expose how big of frauds they are, how they really built their mining farms, what they are actually doing vs. what they’re telling you and why, as well as explain what exactly is going on with Ethereum and why if you’re planning on being able to mine with those GPUs (at least above the cost of your electricity / profitably) the math is not looking good.

Let’s break down what neither the miners or the Ethereum developers want to talk about / remember and break it down!

Bulk Management of Multiple Goldshell ASIC Miners w/ Yotta BC

Yotta BC - Official Goldshell ASIC Bulk Management Tool

One reality of cryptocurrency mining is that you are almost certainly going to need multiple units to reach whatever goals you have. The way most people do this is pay for / ROI on their existing units and then they will add more units and repeat the cycle again.

At first this is easy when you only have a few units but it gets more complex as you add more units. You will need better infrastructure and management tools as you scale up.
I’ve been going through this process for a ASIC farm build-out and wanted to share some of the tools I’ve found and used to make scaling up much more effective.

Today I’m going to cover an official tool from Goldshell called YottaBC that lets you do a lot of cool things like tell all of your miners to change pools at once, view the status of all miners in one fell swoop, fix miners that have lost their IP address and lots of other critical functions. Let’s take a look!

Goldshell BOX ASIC Miner Firmware Recovery Guide

Goldshell Hub - Introduced in firmware 2.2.0

Recently Goldshell released the 2.2.0 update which includes the new “Goldshell Hub” (featured above) which is basically a cloud control center for your miners. I was able to upgrade 23 miners successfully but I had one Mini DOGE and one ST-BOX fail during the upgrade.

After a substantial Google journey and finding some very helpful posts on the VoskCoin forum and reddit I was able to recover both of them without waiting for Goldshell’s response on the situation. I will cover what I used to do so and where to find them in the guide but it is at your own risk and if you aren’t outside of your warranty support period you should almost certainly contact Goldshell instead.

With that caveat/warning given, I have 25 of these miners and only 1-2 were bought directly from Goldshell in the first place so I was not worried about losing my warranty or support period from them but you should be careful here and only proceed if you understand this. Let’s begin!

Fix Home Assistant / HAOS Raspberry Pi USB/SSD Boot Freeze

Home Assistant / HAOS

There are few things I dislike more in this world than getting questions on my setup guides that I don’t know the answer to, but thanks to an investigation by Bill Schatzow we can strike one of those issues off the list!

We’ve had a few comments of people who have encountered this issue over the years. Given that at best only 1% of people who visit the site leave a comment I think it’s safe to say that this issue has plagued thousands of people over the past 10-12 months.

Let’s take a look!

Bobcat 300 Diagnoser Tool / Utility Guide (Helium Mining)

Bobcat 300 Diagnoser Utility

The Bobcat 300 Helium Miner finally has an interface you can use to be able to tell what it’s doing! Better yet, it lets you do a few things like conduct an internet speed test. You can even get a detailed breakdown of which block your miner is on!

In this guide I’ll break down how to access the web interface (easy) and run through some of the features that are available at launch (1.0). The utility started installing on Bobcat 300’s via OTA updates on August 3rd 2021. Let’s begin!

PCIe 1x NVMe on Raspberry Pi?! Compute Module 4 Guide

CableCC Vertical Adapter in Compute Module 4 IO Board

I recently covered all the pieces you need for a complete setup to work with the Raspberry Pi Compute Module 4. Today I want to cover the whole reason I wanted to investigate the Compute Module 4: The PCI express capabilities!

In this guide I’ll cover a couple of 1x PCIe to NVMe adapters I picked up to try doing this with as well as full configuration and setup instructions. Let us begin!

Full Compute Module 4 (Raspberry Pi) Setup / Imaging Guide

Raspberry Pi Compute Module 4 mounted in IO Board

The Raspberry Pi Compute Module 4 is primarily meant for embedded projects and didn’t catch my interest at first. That was until people started absolutely smashing previous records on my Pi storage benchmarking site pibenchmarks.com.

Upon further investigation it turns out that people are breaking these records using the Compute Module 4 since it allows running a NVMe drive through PCI express instead of having to use a USB adapter (the current bottleneck in other Pis).

Wanting to investigate these new capabilities for myself I got a hold of some gear and wanted to write a setup and configuration guide on everything you need for a full CM4 (Compute Module 4) setup and how to get it imaged and configured. Let’s get started!

Review: ViaBTC Mining Pool (Mixed)

Goldshell LB1 and Goldshell HS1 Plus ASIC Miners

In my last series of cryptocurrency related products/services reviews I gave a positive review to the ApeSwap Exchange on the Binance Smart Chain which has continued to be a great exchange and live up to that review.

Today we will be reviewing the ViaBTC mining pool (for multiple cryptocurrencies and not just Bitcoin, lots of harder-to-find alts and that is why I’m using it) and they will not be so fortunate. Let’s jump right into it!
