[Tutorial] Build and run your own Bitcoin node on Ubuntu 19.10

I am finally doing my part and running my own bitcoin node in a small home server.
Most guides I found online were either incomplete, outdated, or explained only how to run bitcoin-qt (graphical interface). So I built a minimalistic guide with the starting point of Ubuntu 19.10 to run the latest Bitcoin core release (v0.19.0.1) as of today.
If you have an old laptop (raspberry pi, NUC, etc even better) a reliable internet connection, and ~ 500Gb of HDD (USB external drive are just fine), you should consider running a node. It's fun, you will deepen your computer knowledge, and you will be supporting the network.

Why are there no packages for Bitcoin in Linux?

Trying to install a Bitcoin core node. I have decent IT knowledge, very little programming knowledge. This is a nightmare trying to get this going. I'm on Ubuntu server 18.04 (very stable). I can't see any application packages available in the software center, nor on the official github repo. I'm getting an error: E: Unable to locate package bitcoin-qt when sudo apt-get install bitcoin-qt AND sudo apt-get bitcoin
Can someone please explain why it is so difficult to setup a full node?

Deployed (on server) Django 3 project doesn't sees static files

#Deployed #Django3 #not #loands #static #files Deployed (on server) Django 3 project doesn't sees static and css files(whole static folder), the local on development machine works perfectly.

The guide that I have followed is [this](https://www.digitalocean.com/community/tutorials/how-to-set-up-django-with-postgres-nginx-and-gunicorn-on-ubuntu-18-04).
- I have et up a Digital ocean droplet with ubuntu 18.04
- my static files can be found here
STATICFILES_DIRS = [os.path.join(BASE_DIR, 'mymainapp/static/')] #STATIC_ROOT = os.path.join(BASE_DIR, 'static') # Removed based [on](https://stackoverflow.com/questions/60354519/django-base-html-extended-to-homepage-html-static-images-appear-but-home-css-d) STATIC_URL = '/static/' MEDIA_ROOT = os.path.join(BASE_DIR, 'mymainapp/media') MEDIA_URL = '/media/' 
- Than all the other staff with Postgres, Nginx, and Gunicorn as in the [guide](https://www.digitalocean.com/community/tutorials/how-to-set-up-django-with-postgres-nginx-and-gunicorn-on-ubuntu-18-04)
- but the static files (image, SVG, css, files doesn't load in)
- I have my bootstrap CSS files downloaded to local directory
- The website is online and if I press F12 in chrome it puts out the following error messages (turning ```DEBUG = True``` does not deliver any more error messages or error page)

- I had the same errors before going thru the guide and just haveing a basic pulled git version of it and running with ```python3 manage.py runserver``` it loads the site but not the css and the static elements
- I have put the base ```/media``` and ```/static``` folders in to git ignore (these should be the one where collect static collets up the element). The original static is under the ```myowndjango-project/myowndjango/static``` and ```myowndjango-project/myowndjango/media```
- I have also set up the nginx as follows
... location /static/ { root /home/myserverusemyowndjango-project; } location /media/ { root /home/myserverusemyowndjango-project; } ... 
What I have tried to solve it
- look for server access log
- run ```/valog/nginx/access.log``` result: ```-bash: /valog/nginx/access.log: Permission denied```
- run ```sudo /valog/nginx/access.log``` result: ```sudo: /valog/nginx/access.log: command not found```
- changing nginx file
... location /static/ { root /home/myserverusemyowndjango-project/myowndjango/static; } location /media/ { root /home/myserverusemyowndjango-project/myowndjango/media; } ... 
- Running
python3 manage.py collectstatic 
(restarted nginx and gunicorn) and it still does the same error.

Thank you for the help.

Is installing and compiling libraries as extremely frustrating and impossible for others as it is for me?

I don't know if it's my unconventional programming setup (VirtualBox Ubuntu 18), but I have never been able to simply follow the steps to compile a project or application without major problems happening.
Here are all some examples from me trying to build openpose tonight. It's what prompted me to make this post:
  1. Cmake must be updated because, for some reason, the default apt-get cmake is still the version from 2017!
  2. I had to specifically install python3.7-dev instead of python 3.6-dev even though everyone builds openpose with python3.5-dev (which I couldn't install).
  3. I had to mix and match commands from three different tutorials because following just one of any of them resulted in errors.
  4. Openpose would not compile because there was a typo in one of the third-party libraries that I found out only after diving deep into github. I had to vim and manually edit the source code to fix this one.
This sounds a bit whiny, and it may just be only to whine. But is this really how major packages are dealt with?
This is just one example, a month ago I spent a whole day just to compile a library by Google called mediapipe. In between these examples have been dozens of other libraries and packages where following the instructions was not sufficient and I needed to dive deep into terminology way above my head to try and debug some stupid problems and it seems to not be getting easier with time.
It just seems like such a major headache and the solutions are so arcane that I can't fathom how anyone even came up with them? It just looks like: Oh, simply apt-get llldldlepellelpv=3.5 the lllldldldelep3.5.1 has the bug on line 3,884 and then copy it into this other directory and make sure it's not done past 2PM otherwise you also have to meet this dependency by sacrificing your 3rd most valued possession by chucking it out of the 4 story apartment (incompatible with non-4-story apartments). This result will then be the 5th post on stack overflow and the only one that works. The others just reiterate the exact things you've already tried in judgemental tones or just go off the deep end completely with some insane-tier fixes, including running overcomplicated batch scripts they made which who knows what they do other than probably remotely install a bitcoin miner.
Plus not to mention that I'm trying to code with some of my classmates and the outcome of each of our slightly different setups results in every possible combination of bugs. No single set of instructions will make a major library compile on all of our ubuntu setups.
The setup of libraries (not even talking about incorporating them into my own project so that mine will compile alongside them) is just an extremely frustrating process. What are the secrets to doing it right and being able to know which magic commands fix the bugs?

Putting together a scripting language hackathon - need advice

I'm putting together a webinar based hackathon for a local Linux user group to learn Bitcoin Scripting Language. First question: there are a number of tutorials on BitcoinScripting Language and I know Bitcoin Cash and SV are forks and,so, the same or am I assuming too much? I know they made changes to the forks but would any of them affect beginners? Or, similarly, are there any similar tutorials for the forks?
Second, I'm assuming the first step for students would be to install a server on their own PCs. It's been years since I have had one and am having a hard time getting one set up. I'm on Ubuntu. I could try to build from source if there was a detailed step-by-step but prefer something easier (not all the Linux group would be able to build from source and the focus is on the scripting language). So could someone walk me through setting up a server?

How to get a public static ip for your local lightning node

My lightning node is a node that is running locally on my server hardware in my house down under, far from the New Jersey Digitalocean datacenter, which is what will come up if you look up the ip of the node. This is done via an OpenVPN tunnel from your local machine to a VPS. I am doing this by renting a VPS from Digitalocean for $20 a month (2 vCPUs, 2GB RAM) running Ubuntu 18.04. You can do this just as easily on a $5 a month VPS with 1 vCPU and 1GB RAM or even a $2.50 a month VPS from Vultr with 512MB RAM. I needed the extra power because I have many web services running there as well.
This setup allows me to have a highly available lightning node, not affected by my home IP address changing. If you are using a mobile connection or have a CGNAT, you wont be able to port forward for your lightning node. This setup allows you to do so. You can also use this to make a portable lightning node, which can get you a full lightning node wherever you have power and internet, without having to mess with network settings. If you don't want others to know your home IP, this is a good option for privacy.
  1. Setup a local lightning node, preferably on a linux machine. I followed the Raspibolt tu`ial (with some tweaks) on a 2 vCPU and 8GB RAM VM running Ubuntu 16.04.
  2. Get a VPS with a static IP address. Digitalocean and Vultr VPSs already are. This VPS wont need much power, so get the cheapest one you can.
  3. Secure the VPS. I used this tutorial. Essentially, setup a non root user, use ssh keys, and setup ufw. Also make sure to allow port 9735 through ufw for lightning. I also additionally made adjustments to the ssh config and installed fail2ban.
  4. Setup an OpenVPN server on the VPS. I used this tutorial.
  5. Install on OpenVPN client on the local linux machine and connect to the server. The tutorial from step 4 shows how to this. Keep this connected for step 6.
  6. SSH into the VPS and figure out the OpenVPN IP address of the client. It should be 10.8.0.x. To figure out the x, setup a simple python web server or something on the local machine on port 8000 or something and open the port on ufw in the local machine. Keep the OpenVPN connection, and use a new ssh session when accessing your local machine. Don't kill the OpenVPN connection, as it may complicate things when finding the ip.
    mkdir testweb
    cd testweb
    echo hello >> index.html
    sudo ufw allow 8000
    python -m SimpleHTTPServer 8000
  7. SSH back into the VPS. Run the curl command below, and try all the numbers between 2-10 for x. When you get hello as your output, then you found the right IP. I found mine at 6. You may have to try higher numbers, but this is unlikely. You can kill your python webserver on your local machine once you find it.
    curl 10.8.0.x:8000
  8. Once you have the IP, you want to make this static, so it doesn't change when you reconnect. This is done on the VPS side, so ssh back into the VPS. This tutorial worked for me. Just make sure to change values like the CommonName and and the IP to match yours (client1 and 10.8.0.x). If it doesn't work search "make openvpn ip static" and look around.
  9. SSH into your local machine, and make the OpenVPN connection persistent. You can kill the OpenVPN connection now. Doing this and this worked for me. If it doesn't work search "openvpn keepalive" or "openvpn auto connect linux" or "make openvpn connection persistent linux".
  10. Restart your local machine, and make sure it connects on boot. Do the python webserver test again, and make sure the same ip is shown on the VPS, and it is still accessible.
  11. SSH back into the VPS. Now, you have to port forward with iptables. you have to add the 2 lines below starting with -A PREROUTING in the same place in your /etc/ufw/before.rules file. Here is what mine looks like. Change the x to your OpenVPN IP. Do sudo ufw disable and sudo ufw enable to restart ufw to update your changes.
    *nat
    :POSTROUTING ACCEPT [0:0]
    -A PREROUTING -i eth0 -p tcp -m tcp --dport 9735 -j DNAT --to-destination 10.8.0.x:9735
    -A PREROUTING -i eth0 -p udp -m udp --dport 9735 -j DNAT --to-destination 10.8.0.x:9735
    -A POSTROUTING -s 10.8.0.0/8 -o eth0 -j MASQUERADE
    COMMIT
  12. SSH into your local machine. Change your lnd.conf to match with this setup, like changing the externalip. Here is what my config looks like, a slight tweak from the Raspibolt one:
    [Application Options]
    debuglevel=info
    maxpendingchannels=5
    alias=GCUBED [LND]
    color=#68F442
    listen=0.0.0.0:9735
    externalip=157.230.95.74:9735
    [Bitcoin]
    bitcoin.active=1
    bitcoin.mainnet=1
    bitcoin.node=bitcoind
    [autopilot]
    autopilot.active=1
    autopilot.maxchannels=5
    autopilot.allocation=0.6
  13. Do a sudo service lnd restart to restart lnd and apply the changes. Remember to do a lncli unlock after any restarts. Your lnd node should now have a public static ip. Look it up a few hours after you do this on 1ml, your ip should be the one of your VPS now.
I am monitoring this for free with uptimerobot. It will notify you if it has gone down. So far mine has been running for 3 days and hasn't gone down.
EDIT: Formatting
EDIT 2: The main reason I didn't use a ddns or a hidden service was mainly for high uptime, and low latency. I am planning on developing a lapp with this node and I didn't want to risk any downtime. Running lightning as a hidden service is a great idea as well, this tutorial shows how to achieve something similar with the clearnet.
EDIT 3: You can achieve a similar result from using TOR

Setting up a lightning node, a channel and closing a channel.

I were planning on setting up a node. I recently started reading about this lightning stuff, I have never had the need for fast trade bitcoins but its interesting. However the lightning network seems a bit scary. So when I set up a channel I load it up with a bit of my coins. If I close it I loose all my money. Is there any way to close a channel gracefully? Or do I have to wait for one of the parties to transfer all the money? What happens if my server crashes, will it forcefully close my channels and I will loose my input coins? Is it possible to restore from backup etc?

Do you have any nice tutorials for setting up a node? I run a Ubuntu server but I assume all GNU/Linux distros will be kinda ok? How much space does a node take, is it like bitcoin where I need to stack up on the entire block chain, 250gb(and growing fast)?

(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:
 
The updates
 
If you would like to tip me
Writing a tutorial like this takes time and effort; tips are appreciated. My Reddcoin address: RqvdnNX5MTam855Y2Vudv7yVgtXdcYaQAW.
     

Overview

 

Steps

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
     

Video

This video shows how long it takes to start Reddcoin Core.   TL;DR:
     

Extra

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.

Lightning node setup - estimation (time needed)?

Hi, at work I may try to sell this idea to my boss, to setup a bitcoin lightning node. We have a good infrastructure and it would be quite cool to have a node running on one of our dedicated VMs.

My boss or the person who will approve/deny this idea may ask me of course how much will this cost, in time and money. I didn't do much research yet, but seen several tutorials how to setup a lightning node... thus I may include also the time to do more research...

Here various tutorials I've found so far:
- Detailed guide to installing LND and Bitcoind on Ubuntu 16.04 LTS for Mainnet (this seems very good for ubuntu users)
- Bitcoin Lightning Node on Ubuntu Linux
- The Lightning Network: How to install and (hopefully) make money
- Installing Lightning Network part 2: Here We Go Again
- Bitcoin Lightning Network: run your node at home for fun and (no) profit (explains how to install LND, which saves space as the blockchain doesn't need to be stored locally)

Other resources:
- Bitcoin Core Download (since I use ubuntu I may use the PPA)
- Lightning LND Releases (this still needs to be compiled)

Can you help me estimating this task? I tried to split it into sub-tasks:
- Install Ubuntu Linux on VM, setup SSH, firewalls, basic dependencies: 4h
- Follow tutorial to install bitcoin and lightning daemons: 8h
- Setup/automate backup: 4h
- Documentation (write down notes -if different than existing tutorials- to make things work & share the results): 4h
- Time spent researching, estimating, making an offelittle presentation of the project: 4h

Total estimation: 3 days
- The initial step to download and verify the blockchain (even if in prune mode it won't be stored, this is required) takes a few days

Is this realistic? Did I forget some parts? Should I estimate more time? (I personally tend to underestimate tasks)

Your feedback is welcome, thank you

[META] New to PC Building? - September 2018 Edition

Intro

You've heard from all your gaming friends/family or co-workers that custom PCs are the way to go. Or maybe you've been fed up with your HP, Dell, Acer, Gateway, Lenovo, etc. pre-builts or Macs and want some more quality and value in your next PC purchase. Or maybe you haven't built a PC in a long time and want to get back into the game. Well, here's a good place to start.

Instructions

  1. Make a budget for your PC (e.g., $800, $1000, $1250, $1500, etc.).
  2. Decide what you will use your PC for.
    • For gaming, decide what games and at what resolution and FPS you want to play at.
    • For productivity, decide what software you'll need and find the recommended specs to use those apps.
    • For a bit of both, your PC build should be built on the HIGHEST specs recommended for your applications (e.g., if you only play FortNite and need CPU power for CFD simulations, use specs recommended for CFD).
    Here are some rough estimates for builds with entirely NEW parts:
    1080p 60FPS ultra-settings modern AAA gaming: ~$1,200
    1440p 60FPS high/ultra-settings modern AAA gaming: ~$1,600
    1080p 144FPS ultra-settings modern AAA gaming: $2,000
    4K 50FPS medium/high-settings modern AAA gaming: > $2,400
    It's noted that some compromises (e.g., lower settings and/or resolution) can be made to achieve the same or slightly lower gaming experience within ±15% of the above prices. It's also noted that you can still get higher FPS on older or used PCs by lowering settings and/or resolution AND/OR buying new/used parts to upgrade your system. Make a new topic about it if you're interested.
    Also note that AAA gaming is different from e-sport games like CSGO, DOTA2, FortNite, HOTS, LoL, Overwatch, R6S, etc. Those games have lower requirements and can make do with smaller budgets.
  3. Revise your budget AND/OR resolution and FPS until both are compatible. Compare this to the recommended requirements of the most demanding game on your list. For older games, you might be able to lower your budget. For others, you might have to increase your budget.
    It helps to watch gaming benchmarks on Youtube. A good example of what you're looking for is something like this (https://www.youtube.com/watch?v=9eLxSOoSdjY). Take note of the resolution, settings, FPS, and the specs in the video title/description; ask yourself if the better gaming experience is worth increasing your budget OR if you're okay with lower settings and lowering your budget. Note that you won't be able to see FPS higher than 60FPS for Youtube videos; something like this would have to be seen in-person at a computer shop.
  4. Make a build on https://ca.pcpartpicker.com/. If you still have no idea how to put together parts, start here (http://www.logicalincrements.com/) to get an understanding of PC part tiers. If you want more info about part explanations and brief buying tips, see the next section below.
  5. Click on the Reddit logo button next to Markup, copy and paste the generated text (in markup mode if using new Reddit), and share your build for review!
  6. Consider which retailer to buy your parts from. Here's a table comparing different retailers: https://docs.google.com/spreadsheets/d/1L8uijxuoJH4mjKCjwkJbCrKprCiU8CtM15mvOXxzV1s/edit?usp=sharing
  7. Buy your parts! Use PCPP above to send you e-mail alerts on price drops or subscribe to /bapcsalescanada for deals.
    You can get parts from the following PC retailers in alphabetical order:
  8. After procuring your parts, it's time to build. Use a good Youtube tutorial like this (https://www.youtube.com/watch?v=IhX0fOUYd8Q) that teach BAPC fundamentals, but always refer to your product manuals or other Youtube tutorials for part-specific instructions like CPU mounting, radiator mounting, CMOS resetting, etc. If it everything still seems overwhelming, you can always pay a computer shop or a friend/family member to build it for you.
    It might also be smart to look up some first-time building mistakes to avoid:
  9. Share your experience with us.
  10. If you have any other questions, use the search bar first. If it's not there, make a topic.

BAPC News (Last Updated - 2018/09/20)

CPU

https://www.tomshardware.com/news/intel-9000-series-cpu-faq,37743.html
Intel 9000 CPUs (Coffee Lake Refresh) will be coming out in Q4. With the exception of i9 (8-core, 12 threads) flagship CPUs, the i3, i5, and i7 lineups are almost identical to their Intel 8000 (Coffee Lake) series, but slightly clocked faster. If you are wondering if you should upgrade to the newer CPU on the same tier (e.g., i5-8400 to i5-9400), I don't recommend that you do as you will only see marginal performance increases.

Mobo

https://www.anandtech.com/show/13135/more-details-on-intels-z390-chipset-exposed
Z370s will now be phased out for Z390s boards, which will natively support Intel 9000 CPUs (preferably i5-9600K, i7-9700K, and i9-9900K).

GPU

https://www.youtube.com/watch?v=WDrpsv0QIR0
RTX 2080 and 2080 Ti benchmarks are out; they provide ~10 and ~20 frames better than the 1080 Ti and also feature ray tracing (superior lighting and shadow effects) which is featured in only ~30 games so far (i.e., not supported a lot); effectively, they provide +25% more performance for +70% increased cost. My recommendation is NOT to buy them unless you need it for work or have lots of disposable income. GTX 1000 Pascal series are still relevant in today's gaming specs.

Part Explanations

CPU

The calculator part. More GHz is analogous to fast fingers number crunching in the calculator. More cores is analogous to having more calculators. More threads is analogous to having more filing clerks piling more work for the calculator to do. Microarchitectures (core design) is analogous to how the internal circuit inside the calculator is designed (e.g., AMD FX series are slower than Intel equivalents even with higher OC'd GHz speeds because the core design is subpar). All three are important in determining CPU speed.
In general, higher GHz is more important for gaming now whereas # cores and threads are more important for multitasking like streaming, video editing, and advanced scientific/engineering computations. Core designs from both AMD and Intel in their most recent products are very good now, but something to keep in mind.

Overclocking

The basic concept of overclocking (OCing) is to feed your CPU more power through voltage and hoping it does calculations faster. Whether your parts are good overclockers depends on the manufacturing process of your specific part and slight variations in materials and manufacturing process will result in different overclocking capability ("silicon lottery"). The downside to this is that you can void your warranties because doing this will produce excess heat that will decrease the lifespan of your parts AND that there is a trial-and-error process to finding OC settings that are stable. Unstable OC settings result in computer freezes or random shut-offs from excess heat. OCing will give you extra performance often for free or by investing in a CPU cooler to control your temperatures so that the excess heat will not decrease your parts' lifespans as much. If you don't know how to OC, don't do it.

Current Products

Intel CPUs have higher GHz than AMD CPUs, which make them better for gaming purposes. However, AMD Ryzen CPUs have more cores and threads than their Intel equivalents. The new parts are AMD Ryzen 3, 5, or 7 2000 series or Intel i3, i5, or i7 8000 series (Coffee Lake). Everything else is outdated.
If you want to overclock on an AMD system, know that you can get some moderate OC on a B350/B450 with all CPUs. X370/X470 mobos usually come with better VRMs meant for OCing 2600X, 2700, and 2700X. If you don't know how to OC, know that the -X AMD CPUs have the ability to OC themselves automatically without manually settings. For Intel systems, you cannot OC unless the CPU is an unlocked -K chip (e.g., i3-8350K, i5-8600K, i7-8700K, etc.) AND the motherboard is a Z370 mobo. In general, it is not worth getting a Z370 mobo UNLESS you are getting an i5-8600K and i7-8700K.

CPU and Mobo Compatibility

Note about Ryzen 2000 CPUs on B350 mobos: yes, you CAN pair them up since they use the same socket. You might get an error message on PCPP that says that they might not be compatible. Call the retailer and ask if the mobo you're planning on buying has a "Ryzen 2000 Series Ready" sticker on the box. This SHOULD NOT be a problem with any mobos manufactured after February 2018.
Note about Intel 9000 CPUs on B360 / Z370 mobos: same as above with Ryzen 2000 CPUs on B350 or X370 boards.

CPU Cooler (Air / Liquid)

Air or liquid cooling for your CPU. This is mostly optional unless heavy OCing on AMD Ryzen CPUs and/or on Intel -K and i7-8700 CPUs.
For more information about air and liquid cooling comparisons, see here:

Motherboard/mobo

Part that lets all the parts talk to each other. Comes in different sizes from small to big: mITX, mATX, ATX, and eATX. For most people, mATX is cost-effective and does the job perfectly. If you need more features like extra USB slots, go for an ATX. mITX is for those who want a really small form factor and are willing to pay a premium for it. eATX mobos are like ATX mobos except that they have more features and are bigger - meant for super PC enthusiasts who need the features.
If you are NOT OCing, pick whatever is cheap and meets your specs. I recommend ASUS or MSI because they have RMA centres in Canada in case it breaks whereas other parts are outside of Canada like in the US. If you are OCing, then you need to look at the quality of the VRMs because those will greatly influence the stability and lifespan of your parts.

Memory/RAM

Part that keeps Windows and your software active. Currently runs on the DDR4 platform for new builds. Go for dual channel whenever possible. Here's a breakdown of how much RAM you need:
AMD Ryzen CPUs get extra FPS for faster RAM speeds (ideally 3200MHz) in gaming when paired with powerful video cards like the GTX 1070. Intel Coffee Lake CPUs use up a max of 2667MHz for B360 mobos. Higher end Z370 mobos can support 4000 - 4333MHz RAM depending on the mobo, so make sure you shop carefully!
It's noted that RAM prices are highly inflated because of the smartphone industry and possibly artificial supply shortages. For more information: https://www.extremetech.com/computing/263031-ram-prices-roof-stuck-way

Storage

Part that store your files in the form of SSDs and HDDs.

Solid State Drives (SSDs)

SSDs are incredibly quick, but are expensive per TB; they are good for booting up Windows and for reducing loading times for gaming. For an old OEM pre-built, upgrading the PC with an SSD is the single greatest speed booster you can do to your system. For most people, you want to make sure the SSD you get is NOT DRAM-less as these SSDs do not last as long as their DRAM counterparts (https://www.youtube.com/watch?v=ybIXsrLCgdM). It is also noted that the bigger the capacity of the SSD, the faster they are. SSDs come in four forms:
The 2.5" SATA form is cheaper, but it is the old format with speeds up to 550MB/s. M.2 SATA SSDs have the same transfer speeds as 2.5" SATA SSDs since they use the SATA interface, but connect directly to the mobo without a cable. It's better for cable management to get an M.2 SATA SSD over a 2.5" SATA III SSD. M.2 PCI-e SSDs are the newest SSD format and transfer up to 4GB/s depending on the PCI-e lanes they use (e.g., 1x, 2x, 4x, etc.). They're great for moving large files (e.g., 4K video production). For more info about U.2 drives, see this post (https://www.reddit.com/bapccanada/comments/8jxfqs/meta_new_to_pc_building_may_2018_edition/dzqj5ks/). Currently more common for enterprise builds, but could see some usage in consumer builds.

Hard Disk Drives (HDDs)

HDDs are slow with transfer speeds of ~100MB/s, but are cheap per TB compared to SSDs. We are now at SATA III speeds, which have a max theoretical transfer rate of 600MB/s. They also come in 5400RPM and 7200RPM forms. 5400RPM uses slightly less power and are cheaper, but aren't as fast at dealing with a large number of small files as 7200RPM HDDs. When dealing with a small number of large files, they have roughly equivalent performance. It is noted that even a 10,000RPM HDD will still be slower than an average 2.5" SATA III SSD.

Others

SSHDs are hybrids of SSDs and HDDs. Although they seem like a good combination, it's much better in all cases to get a dedicated SSD and a dedicated HDD instead. This is because the $/speed better for SSDs and the $/TB is better for HDDs. The same can be said for Intel Optane. They both have their uses, but for most users, aren't worth it.

Overall

I recommend a 2.5" or M.2 SATA ≥ 250GB DRAM SSD and a 1TB or 2TB 7200RPM HDD configuration for most users for a balance of speed and storage capacity.

Video Card/GPU

Part that runs complex calculations in games and outputs to your monitor and is usually the most expensive part of the budget. The GPU you pick is dictated by the gaming resolution and FPS you want to play at.
In general, all video cards of the same product name have almost the same non-OC'd performance (e.g., Asus Dual-GTX1060-06G has the same performance as the EVGA 06G-P4-6163-KR SC GAMING). The different sizes and # fans DO affect GPU OCing capability, however. The most important thing here is to get an open-air video card, NOT a blower video card (https://www.youtube.com/watch?v=0domMRFG1Rw). The blower card is meant for upgrading pre-builts where case airflow is limited.
For cost-performance, go for the NVIDIA GTX cards because of the cryptomining industry that has inflated AMD RX cards. Bitcoin has taken a -20% hit since January's $10,000+ as of recently, but the cryptomining industry is still ongoing. Luckily, this means prices have nearly corrected itself to original MSRP in 2016.
In general:
Note that if your monitor has FreeSync technology, get an AMD card. If your monitor has G-Sync, get a NVIDIA card. Both technologies allow for smooth FPS gameplay. If you don't have either, it doesn't really matter which brand you get.
For AMD RX cards, visit https://www.pcworld.com/article/3197885/components-graphics/every-amd-radeon-rx-graphics-card-you-can-buy-for-pc-gaming.html

New NVIDIA GeForce RTX Series

New NVIDIA 2000 RTX series have been recently announced and will be carried in stores in Q3 and Q4. Until all of the products have been fully vetted and reviewed, we cannot recommend those yet as I cannot say if they are worth what NVIDIA has marketed them as. But they will be faster than their previous equivalents and will require more wattage to use. The 2070, 2080, and 2080 Ti will feature ray tracing, which is a new feature seen in modern CG movies that greatly enhances lighting and shadow effects. At this time, < 30 games will use ray tracing (https://www.pcgamer.com/21-games-will-support-nvidias-real-time-ray-tracing-here-are-demos-of-tomb-raider-and-control/). It's also noted that the 2080 Ti is the Titan XP equivalent, which is why it's so expensive. (https://www.youtube.com/watch?v=Irs8jyEmmPQ) The community's general recommendation is NOT to pre-order them until we see some reviews and benchmarks from reviewers first.
Looks like a couple of benchmarks are out. While keeping other parts equal the following results were obtained(https://videocardz.com/77983/nvidia-geforce-rtx-2080-ti-and-rtx-2080-official-performance-unveiled). So the 2080 and 2080 Ti are better than last generation's 1080 Ti by ~10 and ~20 frames respectively.

Case

Part that houses your parts and protects them from its environment. Should often be the last part you choose because the selection is big enough to be compatible with any build you choose as long as the case is equal to or bigger than the mobo form factor.
Things to consider: aesthetics, case airflow, cable management, material, cooling options (radiators or # of fan spaces), # fans included, # drive bays, toolless installation, power supply shroud, GPU clearance length, window if applicable (e.g., acrylic, tempered glass), etc.
It is recommended to watch or read case reviews on Youtube to get an idea of a case's performance in your setup.

Power Supply/PSU

Part that runs your PC from the wall socket. Never go with an non-reputable/cheap brand out on these parts as low-quality parts could damage your other parts. Recommended branded PSUs are Corsair, EVGA, Seasonic, and Thermaltake, generally. For a tier list, see here (https://linustechtips.com/main/topic/631048-psu-tier-list-updated/).

Wattage

Wattage depends on the video card chosen, if you plan to OC, and/or if you plan to upgrade to a more powerful PSU in the future. Here's a rule of thumb for non-OC wattages that meet NVIDIA's recommendations:
There are also PSU wattage calculators that you can use to estimate your wattage. How much wattage you used is based on your PC parts, how much OCing you're doing, your peripherals (e.g., gaming mouse and keyboard), and how long you plan to leave your computer running, etc. It is noted that these calculators use conservative estimates, so use the outputted wattage as a baseline of how much you need. Here are the calculators (thanks, VitaminDeity).
Pick ONE calculator to use and use the recommended wattage, NOT recommended product, as a baseline of what wattage you need for your build. Note that Cooler Master and Seasonic use the exact calculator as Outervision. For more details about wattage, here are some reference videos:

Modularity

You might also see some info about modularity (non-modular, semi-modular, or fully-modular). These describe if the cables will come connected to the PSU or can be separated of your own choosing. Non-modular PSUs have ALL of the cable connections attached to the PSU with no option to remove unneeded cables. Semi-modular PSUs have separate cables for HDDs/SSDs and PCI-e connectors, but will have CPU and mobo cables attached. Modular PSUs have all of their cables separate from each other, allowing you to fully control over cable management. It is noted that with decent cooling and airflow in your case, cable management has little effect on your temperatures (https://www.youtube.com/watch?v=YDCMMf-_ASE).

80+ Efficiency Ratings

As for ratings (80+, 80+ bronze, 80+ gold, 80+ platinum), these are the efficiencies of your PSU. Please see here for more information. If you look purely on electricity costs, the 80+ gold PSUs will be more expensive than 80+ bronze PSUs for the average Canadian user until a breakeven point of 6 years (assuming 8 hours/day usage), but often the better performance, longer warranty periods, durable build quality, and extra features like fanless cooling is worth the extra premium. In general, the rule of thumb is 80+ bronze for entry-level office PCs and 80+ gold for mid-tier or higher gaming/workstation builds. If the price difference between a 80+ bronze PSU and 80+ gold PSU is < 20%, get the 80+ gold PSU!

Warranties

Warranties should also be looked at when shopping for PSUs. In general, longer warranties also have better PSU build quality. In general, for 80+ bronze and gold PSU units from reputable brands:
Any discrepancies are based on varied wattages (i.e., higher wattages have longer warranties) or updated warranty periods. Please refer to the specific product's warranty page for the correct information. For EVGA PSUs, see here (https://www.evga.com/support/warranty/power-supplies/). For Seasonic PSUs, see here (https://seasonic.com/support#period). For Corsair PSUs, see here (https://www.corsair.com/ca/en/warranty).
For all other PSU inquiries, look up the following review sites for the PSUs you're interested in buying:
These guys are engineering experts who take apart PSUs, analyze the quality of each product, and provide an evaluation of the product. Another great website is http://www.orionpsudb.com/, which shows which PSUs are manufactured by different OEMs.

Operating System (OS)

Windows 10

The most common OS. You can download the ISO here (https://www.microsoft.com/en-ca/software-download/windows10). For instructions on how to install the ISO from a USB drive, see here (https://docs.microsoft.com/en-us/windows-hardware/manufacture/desktop/install-windows-from-a-usb-flash-drive) or watch a video here (https://www.youtube.com/watch?v=gLfnuE1unS8). For most users, go with the 64-bit version.
If you purchase a Windows 10 retail key (i.e., you buy it from a retailer or from Microsoft directly), keep in mind that you are able to transfer it between builds. So if you're building another PC for the 2nd, 3rd, etc. time, you can reuse the key for those builds PROVIDED that you deactivate your key before installing it on your new PC. These keys are ~$120.
However, if you have an OEM key (e.g., pre-builts), that key is tied specifically to your mobo. If you ever decide to upgrade your mobo on that pre-built PC, you might have to buy a new Windows 10 license. For more information, see this post (https://www.techadvisor.co.uk/feature/windows/windows-10-oem-or-retail-3665849/). The cheaper Windows 10 keys you can find on Kinguin are OEM keys; activating and deactivating these keys may require phoning an automated Microsoft activation line. Most of these keys are legitimate and cost ~$35, although Microsoft does not intend for home users to obtain this version of it. Buyer beware.
The last type of key is a volume licensing key. They are licensed in large volumes to corporate or commercial usage. You can find lots of these keys on eBay for ~$10, but if the IT department who manages these keys audit who is using these keys or if the number of activations have exceeded the number allotted on that one key, Microsoft could block that key and invalidate your license. Buyer beware.
For more information on differentiating between all three types of keys, see this page (https://www.tenforums.com/tutorials/49586-determine-if-windows-license-type-oem-retail-volume.html).
If money is tight, you can get Windows 10 from Microsoft and use a trial version of it indefinitely. However, there will be a watermark in the bottom-right of your screen until you activate your Windows key.

MacOS

If you're interested in using MacOS, look into Hackintosh builds. This will allow you to run MacOS to run on PC parts, saving you lots of money. These builds are pretty picky about part compatibility, so you might run into some headaches trying to go through with this. For more information, see the following links:

Linux

If you're interested in a free open-source OS, see the following links:
For more information, go to /linux, /linuxquestions, and /linux4noobs.

Peripherals

Monitors

Keyboards and Mice

Overall

Please note that the cost-performance builds will change daily because PC part prices change often! Some builds will have excellent cost-performance one day and then have terrible cost-performance the next. If you want to optimize cost-performance, it is your responsibility to do this if you go down this route!
Also, DO NOT PM me with PC build requests! It is in your best interests to make your own topic so you can get multiple suggestions and input from the community rather than just my own. Thanks again.

Sample Builds

Here are some sample builds that are reliable, but may not be cost-optimized builds. These builds were created on September 9, 2018; feel free to "edit this part list" and create your own builds.

Sorry for the lack of updates. I recently got a new job where I work 12 hours/day for 7 days at a time out of the city. What little spare time I have is spent on grad school and the gym instead of gaming. So I've been pretty behind on the news and some might not be up-to-date as my standards would have been with less commitments. If I've made any mistakes, please understand it might take a while for me to correct them. Thank you!

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?

Lightning node on Windows - testing, get not connected

Ok after testing BTCPay, C-Lightning, LND on Ubuntu I said ok let's try also the Windows implementation, is just few clicks and done (as it is promoted).
So I followed this github guide that actually send you to this one.
OK, started Bitcoin-core client on Windows 7 x64, with an already synced data folder. Empty bitcoin.conf (none of guides says how to configure the conf file). Wait until the client is full synced. And then launched the windows-node-launcher (from a subfolder inside Bitcoin folder). All good, started slowly and a small popup appeared in systray saying Bitcoin node is syncing. Reviewed the config of Bitcoin and LND through that little app in systray and saw that bitcoin.conf was already filled with some settings. Didn't change anything. After 1 day (with the bitcoin blockchain already synced), the systray popup still says that is syncing and have a red dot. In the tutorial says that we have to leave it to sync until is blue and then green.
I said, ok maybe it has more things to do. So I open that LND Output link, to see what is going on... And I see that LND is not well. Says: 2019-04-06 21:11:29.772 [INF] LTND: Version: 0.6.0-beta commit=v0.6-beta-rc3, build=production, logging=default 2019-04-06 21:11:29.772 [INF] LTND: Active chain: Bitcoin (network=mainnet) 2019-04-06 21:11:29.774 [INF] CHDB: Checking for schema update: latest_version=8, db_version=8 2019-04-06 21:11:29.808 [INF] RPCS: password RPC server listening on 127.0.0.1:10009 2019-04-06 21:11:29.808 [INF] RPCS: password gRPC proxy started at 127.0.0.1:8080 2019-04-06 21:11:29.808 [INF] LTND: Waiting for wallet encryption password.

So what is going on here? I will have to wait indefinitely? Somebody can give some help or explanation? Is this LND node working on Windows Server 2008 or 2012?
