A bit risky? A comparison between Bitcoin and other assets using an intraday Value at Risk approach - Master thesis from Norwegian University of Science and Technology

The following Master thesis from the Norwegian University of Science and Technology (NTNU) assesses the risk of Bitcoin trading. I thought some you over here in /bitcoinmarkets might find it interesting. Here's the link: http://www.diva-portal.org/smash/get/diva2:742882/FULLTEXT01.pdf
Here's the asbtract:
Abstract
The promising cryptocurrency Bitcoin has attracted a lot of attention recently, but the high volatility of the Bitcoin price has so far been a barrier to widespread adoption. Given the way Bitcoin transactions work, users will be exposed to exchange rate risk even for short intraday horizons. This paper analyzes this risk, and compares it to more traditional assets, namely Gold and the Euro/USD exchange rate. To do this we make use of the recent literature on market risk measures for ultra-high-frequency data to construct an intraday Value at Risk measurement. This IVaR is based on a Monte Carlo simulation, where a log-ACD-ARMA-EGARCH model is used to describe the price movements. The results clearly indicate that for the intradaily horizon, Bitcoin is far more risky than Gold and Euro, which may challenge the applicability of Bitcoin as a medium of transaction. However in our opinion this risk is not large enough to outweigh the potential benefits that Bitcoin offers.
Now, discuss.

Why To Believe in Bitcoin

Because you become one who understands that the entire core of the power structure of our society today is rotten through and through. You understand this corruption stems from the fact that since the 70s it's been based on a debt based fiat currency which gives the hands of a few absolute power to create infinite supply of this currency that we sell our time, labor and goods for every second of every day. You also realize that if we can change that core to one where it's based on a non governmental /non corporate controlled hard asset that is the world's first truly finite asset that the people of the world get to decide on the value (supply) that we can take the next step in human evolution and create a world that rather than the current fiat masters, that we all collectively decide what our time is worth and not the other way around.
You realize that it is truly possible to achieve this but that the only way to do so is to take physical possession of your private keys away from any custodial solution as you understand that possession is 10/ 10ths of the law with bitcoin and every Satoshi counts. You then become one of us. One who regardless of what the current fiat currency value stamped on these banker backed exchanges is that you dollar cost average every time you get any extra money. You do it because you want a better future not only for yourself, but also your family and friends. You see it can happen as more and more people do just what you've done and you have your faith in humanity restored even in the darkest days.
Welcome to the people's peaceful revolution that is Bitcoin!

Bitcoin Fullnode Install Guide for Dummies ;-)

Bitcoin Fullnode Install Guide for Dummies ;-)
Feel free to stop at Level 0 or Level 1, which is fine. More advanced configs are offered to those with more tech savvy. This guide, obviously assumes a Windows 10 install, but other OSes work fine, just find a different guide. BTW, the "For Dummies" is a callback to a set of "tech" books in the 90's intended to be as easy as possible. It is in jest and not intended to insult the reader. Finally, if you dislike the formatting, a well formatted copy can be found here
There is a fairly small subset of Bitcoin users that run a full node. I think the idea of running a full node has gotten a bad rap over the years since there is so much talk about running on a Raspberry Pi, or getting zippy SSDs. Although all of this can be fun, it is often not really required at all. Here are some ways to run a full node starting with the very simple. I'll get into more complex configs, but these are all optional.

Tech Skill Level: 0 (the basics)

  1. Download Bitcoin Core
  2. Launch the downloaded installer and install the app
  3. Launch the installed "Bitcoin Core" app and let it run overnight
In many cases, thats it. If your running a new machine with a fairly good internet connection, 8 or 9 hours will be enough to complete the "Initial Block Download" (IBD). This may fill up your drive a bit, but again, on most new machines, 300 GB of space isn't that hard to come by.

Tech Skill Level: 1 (encrypted wallet)

One thing we left out in the level-0 exercise is encrypting your wallet. It's easy enough to do well, but a bit more difficult to do right. The main challenge is that humans generate really poor passwords. If you want a good password, the best way is to use something called "diceware". Basically, you just grab 4 or 5 dice and each throw of the dice represents a certain word on a special list. The throw {1,4,5,3,1} for example would be the word camping on the EFF-diceware-wordlist. So you repeat this a few times until you have a list of 8 or so words which becomes the passphrase you use to encrypt your wallet. Write it down, it is always hard to remember at first. So at level-1 your list becomes:
  1. Download Bitcoin Core
  2. Launch the downloaded installer and install the app
  3. Launch the installed "Bitcoin Core" app and let it run overnight
  4. Choose Encrypt Wallet from the Settings menu
  5. Enter your 8 word (or so) passphrase generated using the Diceware method

Wallet Encryption Dialog

Tech Skill Level: 2 (enable pruning if needed)

Though I said "300 GB of space isn't hard to come by", some times it actually is. If space is an issue, a simple way to fix it is to tell bitcoin to simple take less space. This is called "pruning" and can take that number from 300 GB down to below 5 GB. If you can't find 5 GB, then you'll have to read ahead to level-4 to add USB storage. But the good news is, enabling pruning is pretty easy, we just add another step to our working list:
  1. Download Bitcoin Core
  2. Launch the downloaded installer and install the app
  3. Launch the installed "Bitcoin Core" app and let it run overnight
  4. Do the wallet encryption steps here if you wish
  5. Choose Options from the Settings menu
  6. Choose Prune block storage to: and select the max size for the blocks to use
  7. Exit and restart the bitcoin application for the changes to take effect

Pruning Dialog
Note, even setting this to 1 GB will still leave you with about a 4.5 GB install. The blocks take up a lot of space, but the chainstate and other folders eat up at least 3.5 GB and they can't be pruned. Also, be aware, to disable pruning requires you to perform the entire IBD again. While pruned some other functions my be disabled as well, so just know that pruning does limit some functionality.

Tech Skill Level: 3 (verify the installer)

Although this is arguably something that should be done at level-0, some find the intricacies of comparing hash (thumbprint) values to be tedious and beyond the scope of a beginner. You will find these types of hash compares suggested quite often as a way to prevent running tainted programs. Programs are often tainted by bad disk or network performance, but most often, taint is malicious code inserted by viruses or malware. This is a way to guard yourself against those types of attacks.
What I cover here is a very basic comparison on the certificate, but a more thorough verification advised by mosts uses a program called Gpg4Win, and is beyond the scope of this beginners guide. But regardless, most users should strive to do this minimum level of validation.
  1. Download Bitcoin Core
  2. Launch the downloaded installer
  3. When prompted "Do you want to allow..." click Show more details
  4. In the details section select Show information about the publisher's certificate
  5. In the certificate window select the Details tab
  6. In the Details tab Subject should start with "CN = Bitcoin Core Code Signing Association"
  7. Ensure Thumbprint in Details reads ea27d3cefb3eb715ed214176a5d027e01ba1ee86
  8. If the checks pass, click OK to exit the certificate window and Yes to allow the installer to run.
  9. Launch the installed "Bitcoin Core" app and let it run overnight
  10. Do the wallet encryption steps here if you wish
  11. Do the optional pruning steps here if you wish

Certification Validation Windows
Note: The certificate used to sign the current Bitcoin installer is only valid from March 2020 to March 2021. After that point the thumbprint on the certificate will change. This is by design and intentional. If your reading this post after March 2021, then it is understood that the thumbprint has changed.

Tech Skill Level: 4 (use secondary storage)

We glossed over the "new machine with fairly good internet" part. Truth be known many people do not have fairly new machines, and find the IBD to take longer than the "over night" best wishes. For most people the slowdown is the disk access when calculating what is called chainstate. This requires fast random reads and writes to the disk. If you have an SSD disk, this will be no problem, but if you have a non-SSD "spinning" disk, random writes are always slow. Though an SSD will speed things up, they are pricey, so a nice middle ground may be a simple high-end USB key drive. You can get some with 10 to 15 MB/s random writes for $20 on Amazon. This is usually a order of magnitude faster than a "spinning" disk. And with pruning (see level-2), a small USB drive should be fine.
Once you decide on a drive, the tricky part will be to enable external storage. It requires editing a configuration file and adding a line. First, we want to create a directory on the key drive. You will need to determine the drive letter of your USB key drive. For the sake of this example, we will assume it is D:, but you must determine this yourself and correct the example. Once you know the drive letter, create a blank folder on the drive called Bitcoin. So for this example, creating Bitcoin on drive D: will create the path D:\Bitcoin. Once done, assuming that D: is your drive, here are the new steps including the edit of the configuration file:
  1. Download Bitcoin Core
  2. Launch the installer, verify it, then run it
  3. Launch the installed "Bitcoin Core" app and let it run overnight
  4. Do the wallet encryption steps here if you wish
  5. Do the optional pruning steps here if you wish
  6. Launch "Notepad" by typing "Notepad.exe" in the windows search bar then click Open
  7. Type the line datadir=D:\Bitcoin (depending on your drive letter) in the blank file
  8. Choose Save from the File menu in notepad
  9. Type %APPDATA%\Bitcoin\bitcoin.conf (note the percent signs) in the File name box
  10. Select All Files from the Save as type dropdown
  11. Click the Save button and overwrite the file if prompted
  12. Exit and restart the bitcoin application for the changes to take effect

Save As Dialog
Now that you've reached this level of technical expertise, there are many new configuration options that you can begin to modify if you wish. Most configuration data is contained in the bitcoin.conf file and learning how to maintain it is a key step for a node operator.

Tech Skill Level: 5 (all other customizations)

Here's a short list of various things you can ADD to your bitcoin.conf file. You generally just add a new line for each configuration settings.
  • addresstype=bech32
  • changetype=bech32
The addresstype / changetype allows your wallet to use the native-segwit (bech32) format. This is the most efficient and inexpensive way to spend bitcoin, and is a recommended configuration. The default uses something called p2sh-segwit which is more compatible with older wallets, but more expensive to spend.
  • minrelaytxfee=0.00000011
Changing the minrelaytxfee setting allows you to help propagate lower fee transactions. It will require more memory but TXN memory is capped at 300 MB by default anyways, so if you have enough memory, it is a good setting to choose.
  • dbcache=2048
The dbcache setting controls how many MB of memory the program will use for the chainstate database. Since this is a key bottleneck in the IBD, setting this value high (2048 MB) will greatly speed up the IBD, assuming you have the memory to spare
  • blocksdir=C:\Bitcoin
  • datadir=D:\Bitcoin
In level-4 we discussed moving the datadir to a fast external storage, but the majority of the space used for bitcoin is the blocks directory (blocksdir). Although you should always use for fastest storage for datadir, you are free to use slow storage for blocksdir. So if you only want to consume a small amount of your SSD (assumed D:) then you can keep your blocks on your slow "spinning" drive.
  • upnp=1
One of the harder challenges you may face running a node, is to get incoming connections. If you are lucky, you may find that your firewall and network HW support the uPnP protocol. If they do, this setting will allow bitcoin to configure uPnP to allow incoming connections to your node. Other methods exist to make your node reachable, but they are well beyond the scope of this guide.

Spending an OP_HODL (CheckLockTimeVerify) address with Electrum.

I've been playing around with OP_CHECKLOCKTIMEVERIFY (op_hodl) for the last few weeks since I haven't found it easy to do in many wallets. Eariler I posted on using the CoinBin wallet interface (locally) to do it, and before that I posted a P2WSH bitcoinlib script to do it.
Today I finally sat down and wrote a script using only Electrum's API. You can run it as any Python script by having Electrum installed from source. Or if you're cavalier (and crazy) you can run it directly from the electrum console with the following command, assuming you put the script in C:\temp.
with open(r"C:\temp\elec-p2sh-hodl.py", 'r') as s: exec(s.read())
It should be noted, that one should NEVER do this, since it is effectively giving me control of your Electrum wallet (bad). It is coded to testnet if that is any consolation.
The script is designed to recreate TXN a8110...adc93, but with Electrum 4.0.4, the R-value grinding causes the signature size to differ, causing signature malleability. Apparently CoinBin and bitcoinlib haven't followed Core when they made this change in 0.17.0. The TXN is still valid, just with a different hash.
If you want to spend a different OP_HODL address, you can hopefully see the simple fields required to change.
References: * The new Electrum OP_HODL spend P2SH script * The bitcoinlib OP_HODL spend P2SH script * The bitcoinlib OP_HODL spend P2WSH script * Thread detailing how to spend a P2SH OP_HODL address in CoinBin * Thread initially discussing OP_HODL in general * The original PR to standardize R-value grinding in Bitcoin Core * Thread discussing my surprise at signature malleability * Request to implement R-value grinding in bitcoinlib

Power of the Command Line (bitcoin-cli, hwi, electrum, trezorctl)

I think some of the console tools available with HW wallets today are greatly under utilized. Here's a quick write-up on how to create and sign a TXN very similar to 43d27...1fc06 found on the SLIP-14 wallet. I'll be using TrezorCTL, Electrum, and HWI for the signing. I won't go much into the setup or install, but feel free to ask if you have questions about it. Note, you don't have to use all three of these. Any one will produce a valid signed TXN for broadcast. I just showed how to do it three ways. Whats more some of the Electrum and HWI steps are interchangeable.
ColdCard also has a utility called ckcc that will do the sign operation instead of HWI, but in many ways they are interchangeable. KeepKey and Ledger both have libraries for scripted signing but no one-shot, one-line console apps that I know of. But HWI and Electrum of course work on all four.

TrezorCTL

This is the what most would think of to use to craft and sign TXNs, and is definitely very simple. The signing uses a script called build_tx.py to create a JSON file that is then used by the btc sign-tx command. The whole process is basically:
  1. tools/build_tx.py | trezorctl btc sign-tx -
This just means, take the output of build_tx and sign it. To copy 43d27...1fc06, I wrote a small script to feed build_tx, so my process looks like:
  1. ~/input.sh | tools/build_tx.py | trezorctl btc sign-tx -
But it's all very simple. Note... I used TrezorCTL v0.12.2 but build_tx.py version 0.13.0 1.

input.sh

```

!/bin/bash

secho() { sleep 1; echo $*}
secho "Testnet" # coin name secho "tbtc1.trezor.io" # blockbook server and outpoint (below) secho "e294c4c172c3d87991b0369e45d6af8584be92914d01e3060fad1ed31d12ff00:0" secho "m/84'/1'/0'/0/0" # prev_out derivation to signing key secho "4294967293" # Sequence for RBF; hex(-3) secho "segwit" # Signature type on prev_out to use secho "" # NACK to progress to outs secho "2MsiAgG5LVDmnmJUPnYaCeQnARWGbGSVnr3" # out[0].addr secho "10000000" # out[1].amt secho "tb1q9l0rk0gkgn73d0gc57qn3t3cwvucaj3h8wtrlu" # out[1].addr secho "20000000" # out[1].amt secho "tb1qejqxwzfld7zr6mf7ygqy5s5se5xq7vmt96jk9x" # out[2].addr secho "99999694" # out[2].amt secho "" # NACK to progress to change secho "" # NACK to skip change secho "2" # txn.version secho "0" # txn.locktime ```

Electrum

Electrum is one of the better GUI wallets available, but it also has a pretty good console interface. Like before you need your Trezor with the SLIP-14 wallet loaded and paired to Electrum. I'll assume Electrum is up and running with the Trezor wallet loaded to make things simple.
Like with TrezorCTL, Electrum feeds on a JSON file, but unlike TrezorCTL it needs that JSON squished into the command line. This is a simple sed command, but I won't bore you with the details, but just assume that's done. So the process in Electrum (v4.0.3) looks like:
  1. electrum serialize (create psbt to sign)
  2. electrum --wallet signtransaction (sign said psbt)
Still pretty simple right! Below is the JSON I smushed for #1

txn.json

{ "inputs": [{ "prevout_hash":"e294c4c172c3d87991b0369e45d6af8584be92914d01e3060fad1ed31d12ff00", "prevout_n": 0, "value_sats": 129999867 }], "outputs": [{ "address": "2MsiAgG5LVDmnmJUPnYaCeQnARWGbGSVnr3", "value_sats": 10000000 },{ "address": "tb1q9l0rk0gkgn73d0gc57qn3t3cwvucaj3h8wtrlu", "value_sats": 20000000 },{ "address": "tb1qejqxwzfld7zr6mf7ygqy5s5se5xq7vmt96jk9x", "value_sats": 99999694 }]}

HWI

HWI is an unsung hero in my book. It's a very small clean and simple interface between HW wallets and Bitcoin Core. It currently supports a good range of HW wallets. It keeps itself narrowly focused on TXN signing and offloads most everything else to Bitcoin Core. Again, I'll assume you've imported your Trezor keypool into Core and done the requisite IBD and rescan. And if you don't have the RPC enabled, you can always clone these commands into the QT-console.
To sign our TXN in HWI (v1.1.2), we will first need to craft (and finalize) it in Bitcoin Core (0.21.1). Like in Electrum, we will have to use simple sed to smush some JSON into command arguments, but I'll assume you have that covered. It will take an inputs.json and an outputs.json named separately.
  1. bitcoin-cli createpsbt (create psbt)
  2. bitcoin-cli -rpcwallet= walletprocesspsbt (process psbt)
  3. hwi -f signtx (sign psbt)
  4. bitcoin-cli -rpcwallet= finalizepsbt (get a signed TXN from psbt)
A little more involved, but still nothing too bad. Plus this gives you the full power of Bitcoin Core including integrations with LND (lightning).

inputs.json

[{ "txid": "e294c4c172c3d87991b0369e45d6af8584be92914d01e3060fad1ed31d12ff00", "vout": 0 }]

outputs.json

[{ "2MsiAgG5LVDmnmJUPnYaCeQnARWGbGSVnr3": 0.10000000 },{ "tb1q9l0rk0gkgn73d0gc57qn3t3cwvucaj3h8wtrlu": 0.20000000 },{ "tb1qejqxwzfld7zr6mf7ygqy5s5se5xq7vmt96jk9x": 0.99999694 }]

Conclusion

This may all seem like very low level coding, but is surprisingly simple once you get a knack for it. Whats more, all these platforms support testnet which allows you to practice with valueless coins until you get the hang of it. And, like many things in bitcoin, this is all (mostly) python, which is one of the easier languages to learn.
Enjoy

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.

Why Osana takes so long? (Programmer's point of view on current situation)

I decided to write a comment about «Why Osana takes so long?» somewhere and what can be done to shorten this time. It turned into a long essay. Here's TL;DR of it:
The cost of never paying down this technical debt is clear; eventually the cost to deliver functionality will become so slow that it is easy for a well-designed competitive software product to overtake the badly-designed software in terms of features. In my experience, badly designed software can also lead to a more stressed engineering workforce, in turn leading higher staff churn (which in turn affects costs and productivity when delivering features). Additionally, due to the complexity in a given codebase, the ability to accurately estimate work will also disappear.
Junade Ali, Mastering PHP Design Patterns (2016)
Longer version: I am not sure if people here wanted an explanation from a real developer who works with C and with relatively large projects, but I am going to do it nonetheless. I am not much interested in Yandere Simulator nor in this genre in general, but this particular development has a lot to learn from for any fellow programmers and software engineers to ensure that they'll never end up in Alex's situation, especially considering that he is definitely not the first one to got himself knee-deep in the development hell (do you remember Star Citizen?) and he is definitely not the last one.
On the one hand, people see that Alex works incredibly slowly, equivalent of, like, one hour per day, comparing it with, say, Papers, Please, the game that was developed in nine months from start to finish by one guy. On the other hand, Alex himself most likely thinks that he works until complete exhaustion each day. In fact, I highly suspect that both those sentences are correct! Because of the mistakes made during early development stages, which are highly unlikely to be fixed due to the pressure put on the developer right now and due to his overall approach to coding, cost to add any relatively large feature (e.g. Osana) can be pretty much comparable to the cost of creating a fan game from start to finish. Trust me, I've seen his leaked source code (don't tell anybody about that) and I know what I am talking about. The largest problem in Yandere Simulator right now is its super slow development. So, without further ado, let's talk about how «implementing the low hanging fruit» crippled the development and, more importantly, what would have been an ideal course of action from my point of view to get out. I'll try to explain things in the easiest terms possible.
  1. else if's and lack any sort of refactoring in general
The most «memey» one. I won't talk about the performance though (switch statement is not better in terms of performance, it is a myth. If compiler detects some code that can be turned into a jump table, for example, it will do it, no matter if it is a chain of if's or a switch statement. Compilers nowadays are way smarter than one might think). Just take a look here. I know that it's his older JavaScript code, but, believe it or not, this piece is still present in C# version relatively untouched.
I refactored this code for you using C language (mixed with C++ since there's no this pointer in pure C). Take a note that else if's are still there, else if's are not the problem by itself.
The refactored code is just objectively better for one simple reason: it is shorter, while not being obscure, and now it should be able to handle, say, Trespassing and Blood case without any input from the developer due to the usage of flags. Basically, the shorter your code, the more you can see on screen without spreading your attention too much. As a rule of thumb, the less lines there are, the easier it is for you to work with the code. Just don't overkill that, unless you are going to participate in International Obfuscated C Code Contest. Let me reiterate:
Perfection is achieved, not when there is nothing more to add, but when there is nothing left to take away.
Antoine de Saint-Exupéry
This is why refactoring — activity of rewriting your old code so it does the same thing, but does it quicker, in a more generic way, in less lines or simpler — is so powerful. In my experience, you can only keep one module/class/whatever in your brain if it does not exceed ~1000 lines, maybe ~1500. Splitting 17000-line-long class into smaller classes probably won't improve performance at all, but it will make working with parts of this class way easier.
Is it too late now to start refactoring? Of course NO: better late than never.
  1. Comments
If you think that you wrote this code, so you'll always easily remember it, I have some bad news for you: you won't. In my experience, one week and that's it. That's why comments are so crucial. It is not necessary to put a ton of comments everywhere, but just a general idea will help you out in the future. Even if you think that It Just Works™ and you'll never ever need to fix it. Time spent to write and debug one line of code almost always exceeds time to write one comment in large-scale projects. Moreover, the best code is the code that is self-evident. In the example above, what the hell does (float) 6 mean? Why not wrap it around into the constant with a good, self-descriptive name? Again, it won't affect performance, since C# compiler is smart enough to silently remove this constant from the real code and place its value into the method invocation directly. Such constants are here for you.
I rewrote my code above a little bit to illustrate this. With those comments, you don't have to remember your code at all, since its functionality is outlined in two tiny lines of comments above it. Moreover, even a person with zero knowledge in programming will figure out the purpose of this code. It took me less than half a minute to write those comments, but it'll probably save me quite a lot of time of figuring out «what was I thinking back then» one day.
Is it too late now to start adding comments? Again, of course NO. Don't be lazy and redirect all your typing from «debunk» page (which pretty much does the opposite of debunking, but who am I to judge you here?) into some useful comments.
  1. Unit testing
This is often neglected, but consider the following. You wrote some code, you ran your game, you saw a new bug. Was it introduced right now? Is it a problem in your older code which has shown up just because you have never actually used it until now? Where should you search for it? You have no idea, and you have one painful debugging session ahead. Just imagine how easier it would be if you've had some routines which automatically execute after each build and check that environment is still sane and nothing broke on a fundamental level. This is called unit testing, and yes, unit tests won't be able to catch all your bugs, but even getting 20% of bugs identified at the earlier stage is a huge boon to development speed.
Is it too late now to start adding unit tests? Kinda YES and NO at the same time. Unit testing works best if it covers the majority of project's code. On the other side, a journey of a thousand miles begins with a single step. If you decide to start refactoring your code, writing a unit test before refactoring will help you to prove to yourself that you have not broken anything without the need of running the game at all.
  1. Static code analysis
This is basically pretty self-explanatory. You set this thing once, you forget about it. Static code analyzer is another «free estate» to speed up the development process by finding tiny little errors, mostly silly typos (do you think that you are good enough in finding them? Well, good luck catching x << 4; in place of x <<= 4; buried deep in C code by eye!). Again, this is not a silver bullet, it is another tool which will help you out with debugging a little bit along with the debugger, unit tests and other things. You need every little bit of help here.
Is it too late now to hook up static code analyzer? Obviously NO.
  1. Code architecture
Say, you want to build Osana, but then you decided to implement some feature, e.g. Snap Mode. By doing this you have maybe made your game a little bit better, but what you have just essentially done is complicated your life, because now you should also write Osana code for Snap Mode. The way game architecture is done right now, easter eggs code is deeply interleaved with game logic, which leads to code «spaghettifying», which in turn slows down the addition of new features, because one has to consider how this feature would work alongside each and every old feature and easter egg. Even if it is just gazing over one line per easter egg, it adds up to the mess, slowly but surely.
A lot of people mention that developer should have been doing it in object-oritented way. However, there is no silver bullet in programming. It does not matter that much if you are doing it object-oriented way or usual procedural way; you can theoretically write, say, AI routines on functional (e.g. LISP)) or even logical language if you are brave enough (e.g. Prolog). You can even invent your own tiny programming language! The only thing that matters is code quality and avoiding the so-called shotgun surgery situation, which plagues Yandere Simulator from top to bottom right now. Is there a way of adding a new feature without interfering with your older code (e.g. by creating a child class which will encapsulate all the things you need, for example)? Go for it, this feature is basically «free» for you. Otherwise you'd better think twice before doing this, because you are going into the «technical debt» territory, borrowing your time from the future by saying «I'll maybe optimize it later» and «a thousand more lines probably won't slow me down in the future that much, right?». Technical debt will incur interest on its own that you'll have to pay. Basically, the entire situation around Osana right now is just a huge tale about how just «interest» incurred by technical debt can control the entire project, like the tail wiggling the dog.
I won't elaborate here further, since it'll take me an even larger post to fully describe what's wrong about Yandere Simulator's code architecture.
Is it too late to rebuild code architecture? Sadly, YES, although it should be possible to split Student class into descendants by using hooks for individual students. However, code architecture can be improved by a vast margin if you start removing easter eggs and features like Snap Mode that currently bloat Yandere Simulator. I know it is going to be painful, but it is the only way to improve code quality here and now. This will simplify the code, and this will make it easier for you to add the «real» features, like Osana or whatever you'd like to accomplish. If you'll ever want them back, you can track them down in Git history and re-implement them one by one, hopefully without performing the shotgun surgery this time.
  1. Loading times
Again, I won't be talking about the performance, since you can debug your game on 20 FPS as well as on 60 FPS, but this is a very different story. Yandere Simulator is huge. Once you fixed a bug, you want to test it, right? And your workflow right now probably looks like this:
  1. Fix the code (unavoidable time loss)
  2. Rebuild the project (can take a loooong time)
  3. Load your game (can take a loooong time)
  4. Test it (unavoidable time loss, unless another bug has popped up via unit testing, code analyzer etc.)
And you can fix it. For instance, I know that Yandere Simulator makes all the students' photos during loading. Why should that be done there? Why not either move it to project building stage by adding build hook so Unity does that for you during full project rebuild, or, even better, why not disable it completely or replace with «PLACEHOLDER» text for debug builds? Each second spent watching the loading screen will be rightfully interpreted as «son is not coding» by the community.
Is it too late to reduce loading times? Hell NO.
  1. Jenkins
Or any other continuous integration tool. «Rebuild a project» can take a long time too, and what can we do about that? Let me give you an idea. Buy a new PC. Get a 32-core Threadripper, 32 GB of fastest RAM you can afford and a cool motherboard which would support all of that (of course, Ryzen/i5/Celeron/i386/Raspberry Pi is fine too, but the faster, the better). The rest is not necessary, e.g. a barely functional second hand video card burned out by bitcoin mining is fine. You set up another PC in your room. You connect it to your network. You set up ramdisk to speed things up even more. You properly set up Jenkins) on this PC. From now on, Jenkins cares about the rest: tracking your Git repository, (re)building process, large and time-consuming unit tests, invoking static code analyzer, profiling, generating reports and whatever else you can and want to hook up. More importantly, you can fix another bug while Jenkins is rebuilding the project for the previous one et cetera.
In general, continuous integration is a great technology to quickly track down errors that were introduced in previous versions, attempting to avoid those kinds of bug hunting sessions. I am highly unsure if continuous integration is needed for 10000-20000 source lines long projects, but things can be different as soon as we step into the 100k+ territory, and Yandere Simulator by now has approximately 150k+ source lines of code. I think that probably continuous integration might be well worth it for Yandere Simulator.
Is it too late to add continuous integration? NO, albeit it is going to take some time and skills to set up.
  1. Stop caring about the criticism
Stop comparing Alex to Scott Cawton. IMO Alex is very similar to the person known as SgtMarkIV, the developer of Brutal Doom, who is also a notorious edgelord who, for example, also once told somebody to kill himself, just like… However, being a horrible person, SgtMarkIV does his job. He simply does not care much about public opinion. That's the difference.
  1. Go outside
Enough said. Your brain works slower if you only think about games and if you can't provide it with enough oxygen supply. I know that this one is probably the hardest to implement, but…
That's all, folks.
Bonus: Do you think how short this list would have been if someone just simply listened to Mike Zaimont instead of breaking down in tears?

Some newbie questions about Trezor device and bitcoin wallets

Greetings
I have never owned bitcoin before, but I studied how it works, so I think I have some understanding. I also studied options and it seems hardware wallet is the way to go for safety reasons.
So, question number One, am I correct that:
Unlike a bank account, where you keep one account usually, with bitcoin you keep generating new addresses, so if you own 1 bitcoin, you don't store it on one address, rather, you own many addresses, each containing part of your bitcoin, and when you spend, you just expend some of the addresses and throw them away, and when you receive, you generate new addresses for every transaction, so you accumulate these addresses that each are like a banknote of sorts, each having their own nominal value, and then you spend those banknotes and never use those addresses again. Right?
Question number Two, am I correct that:
All the addresses are generated from a certain big number, "master key" of sorts, which is private to me, which can be written in a form of "seed" which is what the device will give me when initialized, which is what I can use to recover my master key if I lose or break the device?
Question number Three, who does the address generation for bitcoin wallets for new incoming transactions? I assume it's the online wallet Trezor uses, right? So the device does not store any addresses of bitcoin wallets, right? It only stores my master key?
Assuming all are correct, can you please explain, in simpliest terms, how do I restore these addresses themselves, should Trezor online wallet be unavailable? I mean, it's hardly a possibility, but assume I have my seed, or even my Trezor device, but Trezor online wallet is unavailable. Assume I made hundreds of bitcoin transactions and my bitcoin is stored in hundreds of small pieces on different addresses. How do I recover all those? How do I know when to stop, when I have recovered them all? Assuming I don't know the amount I totally own by heart, so I cannot know when to stop (When I found all my bitcoin)?
I mean, it's unlimited, right, the amount of bitcoin addresses that can be generated from my "master key" of my Trezor? So how do I know which of them contain bitcoin? Like, say I have used 200 of them and 100 of them still contain bitcoins, and I lose the device, and have to restore from seed, how does it know that it has to generate only those 200, like, how does it know it doesnt have to generate more addresses, maybe those other addresses contain some bitcoin on them too?
Or does it, generate them always in the same order, so if it sees only blank unused addresses, it assumes it's time to stop? Like, if address 0-200 are all used but 200-300 are all unused still, it assumes it's fine to stop checking?
Also, on an unrelated note, how can I be sure I made no mistake in recording the seed? Can I just wipe the device and restore it from seed right after initializing it and receiving a small bitcoin transaction, to test it and be sure that I can recover my bitcoin in case I lose it? Is the device unlimited in terms of how many times it can be wiped and restored?
Thanks in advance!
