Gridcoin 5.0.0.0-Mandatory "Fern" Release

https://github.com/gridcoin-community/Gridcoin-Research/releases/tag/5.0.0.0
Finally! After over ten months of development and testing, "Fern" has arrived! This is a whopper. 240 pull requests merged. Essentially a complete rewrite that was started with the scraper (the "neural net" rewrite) in "Denise" has now been completed. Practically the ENTIRE Gridcoin specific codebase resting on top of the vanilla Bitcoin/Peercoin/Blackcoin vanilla PoS code has been rewritten. This removes the team requirement at last (see below), although there are many other important improvements besides that.
Fern was a monumental undertaking. We had to encode all of the old rules active for the v10 block protocol in new code and ensure that the new code was 100% compatible. This had to be done in such a way as to clear out all of the old spaghetti and ring-fence it with tightly controlled class implementations. We then wrote an entirely new, simplified ruleset for research rewards and reengineered contracts (which includes beacon management, polls, and voting) using properly classed code. The fundamentals of Gridcoin with this release are now on a very sound and maintainable footing, and the developers believe the codebase as updated here will serve as the fundamental basis for Gridcoin's future roadmap.
We have been testing this for MONTHS on testnet in various stages. The v10 (legacy) compatibility code has been running on testnet continuously as it was developed to ensure compatibility with existing nodes. During the last few months, we have done two private testnet forks and then the full public testnet testing for v11 code (the new protocol which is what Fern implements). The developers have also been running non-staking "sentinel" nodes on mainnet with this code to verify that the consensus rules are problem-free for the legacy compatibility code on the broader mainnet. We believe this amount of testing is going to result in a smooth rollout.
Given the amount of changes in Fern, I am presenting TWO changelogs below. One is high level, which summarizes the most significant changes in the protocol. The second changelog is the detailed one in the usual format, and gives you an inkling of the size of this release.

Highlights

Protocol

Note that the protocol changes will not become active until we cross the hard-fork transition height to v11, which has been set at 2053000. Given current average block spacing, this should happen around October 4, about one month from now.
Note that to get all of the beacons in the network on the new protocol, we are requiring ALL beacons to be validated. A two week (14 day) grace period is provided by the code, starting at the time of the transition height, for people currently holding a beacon to validate the beacon and prevent it from expiring. That means that EVERY CRUNCHER must advertise and validate their beacon AFTER the v11 transition (around Oct 4th) and BEFORE October 18th (or more precisely, 14 days from the actual date of the v11 transition). If you do not advertise and validate your beacon by this time, your beacon will expire and you will stop earning research rewards until you advertise and validate a new beacon. This process has been made much easier by a brand new beacon "wizard" that helps manage beacon advertisements and renewals. Once a beacon has been validated and is a v11 protocol beacon, the normal 180 day expiration rules apply. Note, however, that the 180 day expiration on research rewards has been removed with the Fern update. This means that while your beacon might expire after 180 days, your earned research rewards will be retained and can be claimed by advertising a beacon with the same CPID and going through the validation process again. In other words, you do not lose any earned research rewards if you do not stake a block within 180 days and keep your beacon up-to-date.
The transition height is also when the team requirement will be relaxed for the network.

GUI

Besides the beacon wizard, there are a number of improvements to the GUI, including new UI transaction types (and icons) for staking the superblock, sidestake sends, beacon advertisement, voting, poll creation, and transactions with a message. The main screen has been revamped with a better summary section, and better status icons. Several changes under the hood have improved GUI performance. And finally, the diagnostics have been revamped.

Blockchain

The wallet sync speed has been DRASTICALLY improved. A decent machine with a good network connection should be able to sync the entire mainnet blockchain in less than 4 hours. A fast machine with a really fast network connection and a good SSD can do it in about 2.5 hours. One of our goals was to reduce or eliminate the reliance on snapshots for mainnet, and I think we have accomplished that goal with the new sync speed. We have also streamlined the in-memory structures for the blockchain which shaves some memory use.
There are so many goodies here it is hard to summarize them all.
I would like to thank all of the contributors to this release, but especially thank @cyrossignol, whose incredible contributions formed the backbone of this release. I would also like to pay special thanks to @barton2526, @caraka, and @Quezacoatl1, who tirelessly helped during the testing and polishing phase on testnet with testing and repeated builds for all architectures.
The developers are proud to present this release to the community and we believe this represents the starting point for a true renaissance for Gridcoin!

Summary Changelog

Accrual

Changed

Most significantly, nodes calculate research rewards directly from the magnitudes in EACH superblock between stakes instead of using a two- or three- point average based on a CPID's current magnitude and the magnitude for the CPID when it last staked. For those long-timers in the community, this has been referred to as "Superblock Windows," and was first done in proof-of-concept form by @denravonska.

Groestlcoin 6th Anniversary Release

Introduction

Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything.
The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years.
In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.

UPDATED - Groestlcoin Core 2.18.2

This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables.
NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.

How to Upgrade?

Windows
If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer.
OSX
If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), run the dmg and drag Groestlcoin Core to Applications.

ALL NEW! – HODL GRS Android Wallet

HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled.
HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user.
Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.

ALL NEW! – Vanity Search Vanity Address Generator

NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator.
VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address.
VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase.
VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).

ALL NEW! – Electrum Personal Server

Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node.
It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node.
Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine.
Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in.
Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet.
Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.

Make your own stakebox. Ultimate beginners guide how to compile any wallet on AARCH64 (Raspbery pi and other SBC)

I contemplated to wrote this for a long time, so it's finally time.
As you know a lot of altcoins uses PoS (Proof-of-stake) way of "mining" coins. Which basically means, that you hold coins on your unlocked wallet and you are receiving stakes as a reward. This requires very little power and it can bring you a lot of rewards, at just 10W from the wall.
So first I am using latest Raspbian on RPI4B 4GB in this example.Setting up Raspbian is not part of this process since it's very well documented. I recommend to change user from pi to something else due to security concerns and you can also do other stuff just search "security Raspberry PI" and you find a lot of articles, but this is not the focus of this guide.
I know there are a lot of guides on the internet, but I am using like 5 sources, so it's compiled what other people wrote and some of my research.
I am using AnyDesk insted of SSH or VNC server, because it works it's ligthweit and it just works.
So after you see the gui of Raspbian, just launch terminal (CTRL + ALT + T) and do basic thing:
sudo apt-get update && sudo apt-get upgrade
Than press Y and let it run, after is finished, we need to prepare so dependency packages. Since most of the wallets using Berkeley DB 4.8 we need to obtain it.
So in terminal wrote:
cd cd Downloads wget http://download.oracle.com/berkeley-db/db-4.8.30.NC.tar.gz tar -xzvf db-4.8.30.NC.tar.gz cd db-4.8.30.NC/build_unix ../dist/configure --enable-cxx make sudo make install 
So wait unti it's finished and than you can delete files in Downloads folder in gui or use:
sudo rm -r [folder] 
So next thing we need to install some libraries.
sudo apt-get install git build-essential libtool autotools-dev autoconf pkg-config libssl-dev libcrypto++-dev libevent-dev libminiupnpc-dev libgmp-dev libboost-all-dev devscripts libdb++-dev libsodium-dev 
And pres y and let it run. After that another set of libraries:
sudo apt-get install libqt5gui5 libqt5core5a libqt5dbus5 qttools5-dev qttools5-dev-tools libprotobuf-dev protobuf-compiler libcrypto++- dev libminiupnpc-dev qt5-default 
And then again pres y and let it run. Some wallets need older version of libssl1.0-dev, so for for safe compiling we install that as well:
sudo apt-get install libssl1.0-dev 
Pres y and let it run. Warning don't use sudo-apt get autoremove, since it would wipe this package, since it's old.
Next thing we are going to obtain Bitcoin PPA filest, which can be done like this.
cd /etc/apt/sources.list.d/ sudo nano bitcoin.list 
Paste this in there:
deb-src http://ppa.launchpad.net/bitcoin/bitcoin/ubuntu artful main 
And CTRL+X and than y, then do this:
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv C70EF1F0305A1ADB9986DBD8D46F45428842CE5E sudo apt-get update 
So now we are ready for compiling. So we are going create folders. CD yourself where this folder should be situated, if you for example have plugged in some external drive. Then:
mkdir Crypto cd Crypto 
And then we have to choose wallet which you want to compile. I am choosing Streamies (STRMS) as an example, since it's pretty good coin for staking. So:
mkdir Streamies cd Streamies 
Then go to the github page and click on the green button on the left and click copy to clipboard, which gives you git link.
git clone https://github.com/Streamies/Streamies.git 
Watch the output folder which it creates, it's stated in the first two lines and copy then by highliting the text and CTRL+SHIFT+C copy it to your clipboard.
cd Streamies (this is that git created folder) ./autogen.sh ./configure CPPFLAGS="-I/uslocal/BerkeleyDB.4.8/include -O2" LDFLAGS="-L/uslocal/BerkeleyDB.4.8/lib" sudo make (this could take hours) sudo make install 
And you are done, files is going to be in folder /uslocal/bin (DO NOT delete git created folder, because you are going to need it for faster compiling, when wallet get's and update.)
cd /uslocal/bin 
Now you can list files by:
ls 
And then you can copy/move them where ever you want by using:
sudo mv * [destination full path] 
Let it run and go back to folder where you move those files.
sudo chmod +x streamies-qt (since we want to run wallet) 
In most cases compiled files are going to in format of "shared library" so we need to create script to run it. Open up a text editor from gui or through nano. And paste this to that file:
#!/bin/bash ./streamies-qt 
And save it as a sh file, for example run.sh. Then we need to make it runnable so:
sudo chmod +x run.sh 
Now to run it, it's just:
./run.sh 
And here we are glorious GUI wallet appears and you are done, you can paste blockchain, wallet.dat from other sources, so this migration is pretty easy and you, if you have it on for exaple flash disk.
So this is basic how to compile QT wallets on AARCH64. I am running 7 wallets, 2 of those are Masternodes and RPI 4B 4GB would handle way more, I am at best on half of my RAM.
Some wallets need more package, but it's not much of and issue, since compiling stops and you just copy paste nape which is missing put it in the google and add "apt-get" after the name of package and you are going to see, what is the name of the packages so it can be retreived from package assinstant aka apt-get. So basically:
sudo apt-get install [package name] 
Then press y and again wrote:
sudo make 
This process is going to continue where it was left off, so nothing is going to run from beginning.
Updating wallets is basically exactly same, just repeat steps from "git clone" and after that proceed as it was written above.
So I hope this helps some of you, to use this at home and not on some VPS, if you are anxious as me, to host my wallets on remote server.

Dogecoin on Linux - The Complete Beginner's Guide

I'm writing this because I couldn't find a single condensed guide on compiling the wallet and running mining software on linux, specficially Ubuntu/Linux Mint. I combed Bitcoin and Litecoin forums for similar problems I was running into and eventually got everything nailed down, so here it is in one place, for new Shibes.
If you want to make a Dogecoin directory in your downloads folder to keep things organized, you will need to modify these commands to refelct the change. So instead of going to ~/Downloads/ you will need to go to ~/Downloads/Dogecoin and be sure to put the zipped files there when you download them, but the commands will be the same otherwise.
cwayne18 put in the work to make a PPA for the QT client here.
Ubunutu/Mint/Debian users should be able to install the client with the following commands:
sudo add-apt-repository ppa:cwayne18/doge sudo apt-get update && sudo apt-get install dogecoin-qt 
To update using this method, run
sudo apt-get update && sudo apt-get upgrade dogecoin-qt 
Compiling the Wallet Manually
I suggest using the PPA above, but if you want to compile manually, here you go.
1)Download the newest source from here. If you want to check out the Github page, click here
2)Unzip the package with the native client OR, navigate to your downloads and unzip
cd ~/Downloads unzip dogecoin-master.zip 
3)Now it's time to compile. You will need to install the dependencies, just copy and paste the following code. It will be a fairly large download and could take some time. It is always important to update before installing any new software, so we'll do that first and then install the dependencies.
sudo apt-get update sudo apt-get upgrade sudo apt-get install libssl-dev libdb-dev libdb++-dev libqrencode-dev qt4-qmake libqtgui4 libqt4-dev sudo apt-get install libminiupnpc-dev libminiupnpc8 libboost-all-dev build-essential git libboost1.53-all-dev 
4)Once that is done, go to the doge-coin master directory and compile:
cd ~/Downloads/dogecoin-maste sed -i 's/-mgw46-mt-sd-1_53//g' dogecoin-qt.pro qmake USE_UPNP=- USE_QRCODE=0 USE_IPV6=0 make -j3 
After running the qmake command you will likely see some text similar to
Project MESSAGE: Building without UPNP support Project MESSAGE: Building with UPNP supportRemoved plural forms as the target language has less forms. If this sounds wrong, possibly the target language is not set or recognized. 
It's perfectly normal, so don't worry about that.
Your Dogewallet is ready to go! The executable is in ~/Downloads/dogecoin-maste and called dogecoin-qt. Your wallet information is in ~/.dogecoin. You can run the wallet at any time by opening terminal and typing
cd ~/Downloads/dogecoin-maste ./dogecoin-qt 
Future upgrades to dogewallet are easy. Back up your wallet.dat, and simply follow the same directions above, but you'll be unzipping and building the newer version. You will likely need to rename the old dogecoin-master directory in ~/Downloads before unzipping the newest version and building. Also, it is likely that you will not need to install the dependencies again.
Alternate Method For Installing Dogecoin Wallet from Nicebreakfast
After installing the dependencies listed in step 3, open terminal, then navigate to where you want Dogecoin Wallet stored and run:
git clone https://github.com/dogecoin/dogecoin ./autogen.sh ./configure make 
then when the wallet is updated just run
git pull 
from the dogecoin directory.
GPU Mining
GPU mining requires CGminer. My suggestion is to get the executable already built. The creator of cgminer has removed the built file from his website, but I've uploaded it here
sudo apt-get install pkg-config opencl-dev libcurl4-openssl-dev autoconf libtool automake m4 ncurses-dev cd ~/Downloads tar -xvf cgminer-3.7.2-x86_64-built.tar.bz2 
Don't use anything newer than 3.7.2. The newer versions of CGMiner don't support GPU mining.
That's it! You have cgminer ready to go! You will run cgminer with the following syntax
cd ~/Downloads/cgminer-3.7.2-x86_64-built/ ./cgminer --scrypt -o stratum+tcp://SERVERNAME:PORT -u WORKER.ID -p PASS 
A good guide for fine tuning cgminer can be found here; follow the litecoin example.
EDIT
I had trouble getting cgminer running with a single line command, but running it via an executable .sh file works. This is covered in the cgminer setup guide I posted above but I'll put it here too. In the same directory that has the cgminer executable, you need to make a file called cgminer.sh and make it executable. It should contain the follwing:
export GPU_USE_SYNC_OBJECTS=1 export GPU_MAX_ALLOC_PERCENT=100 export DISPLAY=:0 find *.bin -delete sleep 5 ./cgminer 
Then you can call cgminer in terminal by doing ./cgminer.sh You will need a cgminer.conf file containing all your options. All of this is covered in the guide that is linked above.
A quick note about AMD drivers: They used to be a huge PITA to install and get working, but the newest Catalyst drivers are great. There's a GUI installer, everything works out of the box, and there is a lot of documentation. You can download them here: AMD Catalyst 14.6 Beta Linux
CPU Mining
For CPU mining I use minerd because it doesn't require any work to get running, simply download it and get to work. Download the built file for your machine 32-bit or 64-bit, and then unzip it and you're ready to go!
cd ~/Downloads tar -xvf pooler-cpuminer-2.3.2-linux-x86.tar.gz 
The executable is called minerd and it will be in ~/Downloads but you can move it to wherever you like. To run it, pull up terminal and do
cd ~/Downloads minerd --url=stratum+tcp://SERVER:PORT --userpass=USERNAME.WORKERNAME:WORKERPASSWORD 
You're done! Happy mining!
Common Issues
I ran into this and I've seen others with this problem as well. Everything installs fine but there is a shared library file that isn't where it should be. In fact, it isn't there at all.
 libudev.so.1: cannot open shared object file: No such file or directory 
In terminal, do
sudo updatedb locate libudev.so.0.13.0 
And it will probably return a path /lib/x86_64-linux-gnu. Inside that directory there's a library file called libudev.so.0.13.0. You'll need to make a symlink (aka shortcut) that links libudev.so.1 to libudev.so.0.13.0 So, assuming you're working with libudev.so.0.13.0 do this
cd /lib/x86_64-linux-gnu sudo ln -s libudev.so.0.13.0 libudev.so.1 
Now if you do
ln -l 
You should see
libudev.so.1 -> ./libudev.so.0.13.0 
Meaning you've made the symlink. Also, the text for libudev.so.1 will be blue.

(Updated) [Staking] Reddcoin Core client GUI wallet on a Raspberry Pi Model 3B

Intro

This thread is an update to my first Reddcoin staking tutorial that was written 7 months ago.
 
The reason for the update
My Reddcoin Core software crashed and became unusable. My Raspberry Pi 3B would lag and freeze, I couldn't stake anymore.
 
Instead of just redoing everything the same way, I wanted to see if I could improve on 3 points:

Backup
Backup your wallet to prevent losing the RDDs in your wallet! There are two methods to backup, do both. Make new backups if you create a new receiving address!
 
 
   
Boot with only 1 USB drive plugged in:
Make sure only the USB drive (with the swap partition and data partition) is plugged in when you boot up your Raspberry Pi. This to make sure the swap partition (/dev/sda1) is recognized correctly.   If you boot up with multiple USB drives, Lubuntu might see the USB drive with the swap partition as the second drive (instead of the first drive), and ignore the 2 GB swap partition. If this happens, starting Reddcoin can render the Raspberry Pi unresponsive.
   
Connection issues If you have issues syncing the blockchain because you have 0 network connections, please follow the instructions in this thread.
   
Start Reddcoin Core easier
Run a shell script (.sh file), so you can start Reddcoin just by double clicking on an icon on your Desktop.
   
Minimization options
Adjust minimization options, so you can safely press on the X button (the close/exit button on the upper right corner).
   
RealVNC VNC Viewer (client) and VNC Connect (server): To remote connect to the Raspberry Pi, I use VNC Viewer ad VNC Connect from RealVNC.
 
   
Chromium as browser: The updates break Firefox, the browser crashes when you try to run it. Install another browser, Chromium, to solve this issue.
   
Updates / Upgrades
If Software Updater shows up and tells you that there is updated software available, do not install the updates using Software Updater. Use LXTerminal to update Lubuntu.

Getting frustrated with Ubuntu. Are my experiences the norm for a Linux user?

Let me start off by saying that I'm not a total newb, but still pretty green. I like to believe I'm capable with computers, and know enough to figure out most issues. I also have a pretty solid general understanding of how they function. Been a Windows user most of my life, but decided to make the switch to Linux a few years back.
My experiences thus far are making me reconsider the switch, despite the fact that I've really become opposed to using Windows. I'm curious if I should expect more of the same indefinitely, or if my experiences up to this point are unusual, and I should expect to reach a point where I can just use the OS, instead of spend hours trying to perform every task.
It all started when I downloaded Ubuntu about three years ago. I easily got it installed as a dual boot on a Windows machine. Had to start by allocating disk space in Windows for the new Linux install, prepared a live usb, went through the install, cake. Then I started trying to do stuff, like use a printer. Well HP doesn't make a driver for Linux and, probably, 2-4 hours of research led to me still not having a working printer. I found a driver, but the process to get it installed did not work as it was supposed to. I forget the specifics, but I followed a tutorial to the T, but ran into unforeseen installation issues, and never could figure out how to get the process complete.
After that I started running into issues with the FireFox browser. I've alwasy used FF on Windows with no issues. On Ubuntu it ran slower than dial-up from the mid-90's. Again, 2-4 hours worth of research and several changes to things like FF settings, disabling add-ons, etc., and I still had no fix.
Still I wasn't deterred. Then the dual boot broke. I tried boot repair. No dice. Tried for several hours to get it working. Asked about it on forums, sent in results of boot repair (where I forget) only to get no response, and finally I threw in the towel.
I also struggled to get Bitcoin Armory working, with some very frustrating success, but I didn't count that against Linux, since it was very new software, and I wasn't surprised it was buggy.
Fast forward to today. I've been using Windows for a couple years, with few attempts made to use Linux, except for trying to retrieve a very small amount of BTC from Armory, which consumed about three weekends of my life to finally achieve.
Now I've decided to give it another go. I downloaded UbuntuStudio b/c I'd like to use some of the music production software that comes with it.
Following some tutorials online, I tried to connect my midi keyboard to the computer using QJackCtl. I couldn't remember the issue that I ran into when starting to type this up, so I tried to repeat the process, only to have the program crash during start up, three times. The computer had literally just restarted 20 minutes ago, so I doubt a reboot would work, but maybe. It's almost funny at this point. I'm really disappointed that I can't get the audio software that came with the distro working "fresh out of the box." Maybe with a few hours, or weekends, worth of research?
I've also been getting a system error message every time I login. I posted a query on the Ubuntu forums. That issue has yet to be sorted out.
I hesitate to include this next part, because it involves software that is really still in it's early stages, and I'm trying to be realistic in taking the perspective that any problems I encounter are with the new software, not Ubuntu, but the fact that I had zero problems getting the same stuff to work in Windows just adds to my frustration with Ubuntu.
Everything I'm about to describe is involved with installing monero mining and wallet software. The exception is the AMD drivers needed for the GPU I'm using to mine. Those I expected to work without issue. I followed the directions for installing the AMD drivers for Ubuntu on the AMD website, and the program would not work. After, you guessed it, 2-4 hours of research, I finally, almost by accident, installed an older version of the driver software. Boom, it worked. WTF man?! When I installed the Windows version it took 2 minutes.
Moving on, I tried getting the xmr-stak mining software working. This took me several hours, spread over several days to sort out. Same with the monero-gui wallet, which actually I've only got half-way working. In fact, I've tried installing the monero-gui by two different ways. In the process I've inadvertently got the monerod daemon running, but not the gui. Actually, the monerod daemon starts with the computer and I haven't even started trying to figure out how to turn that off, since what's the point of having it run if I can't use the gui?
In Windows I had all of this up and running in a couple of hours. And in saying that I'm prepared for the "if you like Windows so much then use that!" or "you're just too thick to figure it out!", but I don't like Windows, and I don't think it's a matter of not figuring it out. It seems to me that the reason I've spent dozens of hours just trying to get things to work in Linux is that nearly every time I've tried to do something, there is inevatably some error along the way where following the directions isn't good enough, and sorting out the issue is a feat in and of itself.
I just want to know if this is unusual, or if this is how it's going to go forever if I keep using Linux. Is my experience typical?
TL;DR: I've had a litany of issues and spent countless hours trying to fix them using Linux. Is this rare, and I've just had an unusual experience, or actually pretty common, and I should just accept it as the cost of using an open source OS?

Vertnode - An automated solution for installing Vertcoin node(s) on Single Board Computers

Hello Vertcoin Community,
Eager to contribute to the Vertcoin Community I began creating step by step walkthrough guides on how to get a Vertcoin node up and running on a Raspberry Pi, Raspberry Pi Zero and Intel NUC. Along with information to get a Vertcoin node up and running was also optional steps to install p2pool-vtc.
I decided that while this step by step guide might be helpful to a few, a setup script may prove to be useful to a wider range of people. I have this script to a point where I think it may be productive to share with a bigger audience, for those who are brave and have this hardware sitting around or like to tinker with projects; I invite you to test this setup script if you are interested, if you run into errors any sort of verbose console output of the error proves to be extremely helpful in troubleshooting.
The script was designed to produce a “headless” server... meaning we will not be using a GUI to configure Vertcoin or check to see how things are running. In fact, once the server is set up, you will only interact with it using command line calls over SSH. The idea is to have this full node be simple, low-power, with optimized memory usage and something that “just runs” in your basement, closet, etc.
Why run a headless node on a Single Board Computer?
The idea is to have this full node be simple, low-power, with optimized memory usage and something that “just runs” in your basement, closet, etc.
Required: USB Flash Drive 6GB - 32GB
Please note that the script was designed for Single Board Computers first and looks for an accessible USB Flash Drive to use for storing the blockchain and swap file, as constant writing to a microSD can degrade the health of the microSD.
Supports

Hardware

All of the hardware listed above is hardware that I have personally tested / am testing on myself. The plan is to continue expanding my arsenal of single board computers and continue to add support for more hardware to ensure as much compatibility as possible.
Functionality
It is worth noting that LIT can be ran with multiple configurations, the ones displayed in the Post Installation Report reflect values that run LIT with the Vertcoin Mainnet. Please be aware that the Vertcoin Testnet chain has not been mined 100% of the time in the past, if you make transactions on the Vertcoin testnet that do not go through it is likely because the chain has stopped being mined.
BE CAREFUL WITH YOUR COINS, ONLY TEST WITH WHAT YOU ARE OKAY WITH LOSING IF YOU USE THE MAINNET.

I've included some documentation on LIT I created which includes information I found to be useful: https://github.com/e-corp-sam-sepiol/vertnode/blob/mastedocs/lit.md

Vertnode | Automated Vertcoin Node Installation Script

https://github.com/e-corp-sam-sepiol/vertnode

Recommended: Use Etcher to install the chosen OS to your microSD card / USB flash drive.

If you intend on installing Ubuntu Server 16.04 to your Intel NUC please use Etcher to install the .iso to your USB flash drive.
https://etcher.io/
PLEASE NOTE THIS SCRIPT MAY GIVE AN ERROR. THIS IS THE NATURE OF TESTING. PLEASE REPORT YOUR ERRORS IF YOU WANT THEM TO BE FIXED/RESOLVED. THANK YOU FOR BETTERING THE DEVELOPMENT OF THIS SCRIPT.

Ubuntu Server 16.04 Setup Details

You can use different clients to ssh into your node. One option is using PuTTY or Git Bash on Windows which is included in the desktop version of Git. If you are using Linux you can simply open a new terminal window and ssh to the IP address of your node (hardware you intend installing the Vertcoin node on).
You will need to know the IP address of your node, this can be found on your router page.
ssh 192.168.1.5 -l pi For example, this command uses ssh to login to 192.168.1.5 using the -l login name of pi. The IP address of your node will likely be different for you, in this example I am logging into a Raspberry Pi which has a default login name of pi.
A brief list of commands that can be used to check on the Vertcoin node status:
vertcoin-cli getblockchaininfo | Grab information about your blockchain
vertcoin-cli getblockcount | Grab the current count of blocks on your node
vertcoin-cli getconnectioncount | Grab the current count of connections to your node. A number of connections larger than 8 means that you have incoming connections to your node. The default settings are to make 8 outgoing connections. If you want incoming connections please port forward your Raspberry Pi in your Router settings page.
vertcoin-cli getpeerinfo | Grab the information about the peers you have connected to / are connected to
vertcoin-cli getnettotals | Grab network data, how much downloaded/upload displayed in bytes
tail -f ~/.vertcoin/debug.log | Output the latest lines in the Vertcoin debug.log to see verbose information about the Vertcoin daemon (ctrl+c to stop)
Thank you to all who have helped me and inspired me thus far, @b17z, @jamesl22, @vertcoinmarketingteam, @canen, @flakfired, @etang600, @BDF, @tucker178, @Xer0
This work is dedicated to the users of Vertcoin, thank you for making this possible.
7/20/2018 Thank you @CommodoreAmiga for the incredibly generous tip <3

Step by step in staking Redd with Raspberry Pi 3

Before I start, I would like to pay complete credits to these two guys :)
https://www.reddcointalk.org/topic/2679/reddcoin-staking-via-ubuntu-mate-on-raspberry-pi-3-model-b-march-2018 (most of my steps, if not all, are from this link)
https://github.com/joroob/reddcoin/blob/mastedoc/build-arm.md
All the steps I am writing is ABSOLUTELY NECESSARY, please don't try to skip it because I did, and it doesn't work.
step 1: get a Raspberry Pi B https://www.raspberrypi.org/products/#buy-now-modal
step 2: make sure you get proper power supply 5v 2A - the Pi will mine, it will need sufficient power. Regular USB samsung charger will not work.
step 3: get proper micro SD card (SanDisk for example) 32Gb++
step 4: USB + Mouse keyboard
step 5: flash micro SD card with Ubuntu MATE
Download Ubuntu Mate image: https://ubuntu-mate.org/raspberry-pi/
Download Etcher: https://etcher.io
After finishing downloading, use Etcher to write/flash the image on micro SD card
After this, your SD card contains Ubuntu MATE OS.
step 6: Place SD Card into Raspberry Pi 3 and start it up. You should be able to see Ubuntu OS! Congrats!
step 7: Connect to wifi or internet cable (internet is better and faster)
step 8: OPTIONAL - turn off UI OS, so that things will work faster
Open XTerminal:
sudo systemctl disable lightdm.service (to turn UI off) 
in case you want to turn UI on again, run this:
sudo systemctl start lightdm.service (to turn UI on) 
step 9: install all dependencies
sudo apt-get update && sudo apt-get install git build-essential libqt4-dev libprotobuf-dev protobuf-compiler libtool autotools-dev autoconf libssl-dev libboost-all-dev wget pkg-config sudo add-apt-repository ppa:bitcoin/bitcoin sudo apt-get update sudo apt-get install db4.8 sudo apt-get install libminiupnpc-dev sudo apt-get install libqrencode-dev Reboot 
step 10: add additional RAM (sort of) in case the App need it, this is call "Create Swap file"
sudo fallocate -l 1G /swapfile sudo chmod 600 /swapfile sudo mkswap /swapfile sudo swapon /swapfile echo ‘/swapfile none swap sw 0 0’ | sudo tee -a /etc/fstab 
step 11: Build Berkeley Database
wget http://download.oracle.com/berkeley-db/db-4.8.30.NC.tar.gz tar xfvz db-4.8.30.NC.tar.gz cd db-4.8.30.NC cd build_unix ../dist/configure --enable-cxx make sudo make install 
step 11.5: Set BerkeleyDB path
export CPATH="/uslocal/BerkeleyDB.4.8/include" export LIBRARY_PATH="/uslocal/BerkeleyDB.4.8/lib" export LD_LIBRARY_PATH=/uslocal/BerkeleyDB.4.8/lib/ 
step 12: Build Reddcoin Wallet
---download source code ---- only source from joroob/reddcoin will work because some stweak was needed for ARM CPU
cd ~ git clone https://github.com/joroob/reddcoin.git 
---build reddcoin ----
cd reddcoin ./autogen.sh ./configure --with-gui=no --disable-tests cd src make sudo make install 
If you finish this, you are in a great position!!!
step 13: Create reddcoin configuration file
cd ~ mkdir .reddcoin && cd .reddcoin nano reddcoin.conf rpcuser=YOUR OWN USERNAME, YOU DONT NEED TO REMEMBER THIS, MAKE IT AS LONG AS YOU WANT rpcpassword=YOUR OWN PASS WORD, YOU DONT NEED TO REMEMBER THIS, MAKE IT AS LONG AS YOU WANT 
step 14: Use bootstrap
(At this point, you had a running reddcoin daemon, now you can start staking. But syncing the full chain takes long time.)
cd ~/.reddcoin wget https://github.com/reddcoin-project/reddcoin/releases/download/v2.0.1.2/bootstrap.dat.xz xz -d bootstrap.dat.xz 
step 15: start the reddcoin daemon service cd ~/reddcoin/src ./reddcoind -daemon
After this, you can test if the daemon is working, by perform this command: ./reddcoin-cli getblockcount
step 16: if your app is not able to sync, it is probably the firewall issue with OS, run this to allow port 45444 (used by Reddcoin) and redo step 15
sudo iptables -I INPUT 1 -i eth0 -p tcp --dport 45444 -j ACCEPT sudo iptables -A OUTPUT -p tcp --dport 45444 -j ACCEPT 
step 17: open BEER and enjoy! This is a MUST or the daemon will stop working! I am not kidding!
step 18: Actually, i forgot to mention you need to execute this command for the wallet to stake:
reddcoind walletpassphrase $yourpassword 9999999 true 
ADDITIONAL REMARKS:
From my PC: I am using putty to execute the command, winSCP to monitor the file location on raspberry.
Moving Red Coins out of exchange really a big move, start with normal wallet, don't start with this tutorial :) Ever since I move my coins out of exchange, I am free from all of the ups and downs! Really!
So guys and gals, Redd On!
UPDATE 18 Mar: my first stake has arrived after 6 days staking :)
In case you want to tip me: RaF3TeWqgTzAdnaZQffnsxS74dag13zsAY
Edit 1: Format stuff
Edit 2: Add step 18 to execute staking command.
Edit 3: In case you don't want to compile the source code, you can download my compile version here: https://github.com/hieplenet/reddcoin/releases/tag/v2.0.0.0 (but doing this, you should be aware of the risk of me changing source code for my benefit - I don't change any thing, but you should be cautious, this is the internet :) )

Ledger HW.1 review and guide for use w/Electrum development version.

Review

I've been really interested in hardware solutions for private key storage. Without jumping in head first and going for the obvious choice I decided to try to least expensive option first: Ledgers HW.1. At the time or writing one can buy a HW.1 for 15€ or 0.0717 btc.
Mine took about 2 weeks to arrive in a hand written envelope from France. Inside was a piece of paper wrapped around a card the exact same dimensions as a US drivers license/credit card. The HW.1 is to be snapped out and folded over as explained on the site. Here is a pic of the device "assembled" next to the card it was snapped out of and plugged into a usb port on a laptop for perspective.
Ledger seems to have some sort of partnership with GreenAddress, but I don't like having a third party involved in my transactions. Regardless how 'ungoxable' they are bitcoin to me is about taking back full control. Therefore I chose to figure out how to use the device with Electrum. There is no guide for this on their site as the process is not simple. However I was able to achieve it and I will share my experience.
I would also like to mention here that this whole process took me about two days of sporadic work to accomplish and a few emails to support. I ended up emailing back and forth with Nicolas Bacca, Ledgers CTO. He was helpful and really quick to answer my questions.
Overall my experience has been really positive and I can honestly recommend purchasing. I'm really excited to try out some other products from Ledger.
The first step is installing electrum development version as described on their site. From a Debian distro I had problems with dependencies, but from a Debian/Ubuntu distro the process was near effortless. I won't go into details on how to install electrum as that is a guide in itself.
Regardless which client you use with the HW.1 you will still need to install the drivers.
What follows is a guide I've put together for the setup and use of the HW.1 with electrum development version on a Debian/Ubuntu os.

Guide

We'll start the electrum gui from the command line along with two options.
-v, --verbose - show debugging information -o, --offline - remain offline 
Here's is what the full command will look like:
$ electrum -v -o 
At which point the gui will open and present you with the entry panel.
Next screen you'll tell it that are making a BTChip wallet.
The next info we receive is explaining the next step. Basically telling us that we can create a completely new wallet now, or re-create one from a seed that we have backed up.
We are now presented with the option to execute creation of a new seed or re-creation of a previous one. For this guide I will choose to create a 'New Wallet'. (Note: it would be really cool if someone could explain to me how to turn a 12 word mnemonic into a 128 bit hexidecimal string as would be inputted here).
The next screen, 2/3 in the creation steps, will have us choose a security profile (2fa or pin only) and a pin. Basically 'hardened' is 2fa with the second factor being a 4 digit pin and the transaction details that the HW.1 will print to a text editor (as you will see with the seed backup in upcoming steps).
Of course we will choose 'Hardened' for the most fun... and security. Then choose a strong PIN.
Since we chose 2fa we now have to tell what type of keyboard we're using.
Next an apt warning about backing up your seed.
Last step before secure backup of seed. We will be removing the HW.1 before hitting next.
Reading this carefully, it's telling us to open a text editor (even a terminal will do), make it the active window, and plug the HW.1 back in.
Opening a text editor, placing the cursor on it, and plugging the HW.1 back in we get a printout in a few seconds in the following format.
Seed 128bitHexidecimalX 
We will remove 'Seed' from the beginning and 'X' from the end. What remains is our seed. We will save it in case of an issue with our HW.1 (lost, damaged, forgotten pin, etc.).
Note: To restore from this Master Private Seed one needs to put 'xpriv' at the beginning of the seed for electrum to recognize it. Using the seed from above if, we didn't have our HW.1 we could input the following to regenerate our private keys:
xpriv128bitHexidecimal 
After backing up our seed we can click the 'Next' button. Where we will be asked if we backed our seed up.
For some reason, I received this after confirming that I had backed my seed up.
Ok, I took the HW.1 out and put it back in. Then clicked 'Yes'. At which point we are presented with the following screen. Enter the pin and complete the setup by clicking 'Finish'.
The wallet/device are now created and we have a backup (at least one). Now we can spend some coins. Let's open our wallet with the HW.1 plugged in. This time we'll add an option for our chosen wallet path and remove the option to remain offline.
-w WALLET_PATH, --wallet=WALLET_PATH - wallet path 
The command should look like this:
$ electrum -v -w /path/to/wallet.file 
Right away we're prompted with the same two screens we saw at the beginning.
We won't see these again if we keep our wallet file, or continuously use the default_wallet created by electrum when the -w option is not used. For now we will answer these questions the same as at the beginning.
The next window will be how electrum will start from now on when this wallet is used with the HW.1.
Now we have electrum running normally. This is a good place to note that a 'watching-only' version of this wallet can be opened even without the presence of the HW.1. So you can retrieve addresses without the privkeys at any time. Funding addresses in normal, spending is a little different.
We'll create the spend from the gui the standard way.
After clicking 'Send' we are presented with this screen. READ THIS SCREEN CAREFULLY!
After careful reading we should have determined that we are to open a text editor and make it the active screen. Take out the HW.1 and put it back in. At this point the HW.1 will print into your text editor the details of your spend and your 2fa pin in the following format.
Powercycle then confirm transfer of x.xxxx BTC to 1xxbitcoinaddress fees x.xxxx BTC change x.xxxx BTC with PIN 1234 
From this output we can see how many btc are being sent to which address. In this case there is no change. The PIN in this scenario is '1234'. This is what will be entered into the 2fa challenge. DO NOT CLICK 'OK' YET.
After entering our PIN we have to remove the HW.1 and then put it back in before clicking 'OK'. After doing this we can click 'OK'. At which point we are presented with a familiar screen.
The transaction is signed and ready for the network. We can broadcast from here or save it for later.
Feedback welcomed.
