The example under verilog/interactive showcases how to create a simple interactive visual Verilog example using Verilator and SDL.
You could e.g. expand such an example to create a simple (or complex) video game for example if you were insane enough. But please don't waste your time doing that, Ciro Santilli begs you.
The example is also described at: stackoverflow.com/questions/38108243/is-it-possible-to-do-interactive-user-input-and-output-simulation-in-vhdl-or-ver/38174654#38174654
Usage: install dependencies:then run as either:Tested on Verilator 4.038, Ubuntu 22.04.

On May 19, 2020, Lazlo announced on the Bitcoin Forum at: bitcointalk.org/index.php?topic=137.msg1195Ciro Santilli remembers his father always telling him how when Ciro was small, he would try to grasp the value of money by converting it into how many pizzas he could buy. Well, at least he was not alone.
I'll pay 10,000 Bitcoins for a couple of pizzas.. like maybe 2 large ones so I have some left over for the next day. I like having left over pizza to nibble on later. You can make the pizza yourself and bring it to my house or order it for me from a delivery place, but what I'm aiming for is getting food delivered in exchange for bitcoins where I don't have to order or prepare it myself, kind of like ordering a 'breakfast platter' at a hotel or something, they just bring you something to eat and you're happy!
User bitcoin2paysafe then asks the fundamental practical question:and Lazslo replies:
In which country do you live?
Jacksonville, Florida
zip code 32224
United States
User ender_x then points out afterward:so it is a slightly bad deal even then!
10,000... Thats quite a bit.. you could sell those on www.bitcoinmarket.com/ for $41 USD right now..
Three days later Lazlo's asks again on the thread:and one day later he confirms that the sale was made without naming the buyer:where "jercos" is presumably the Bitcoin Forum username of the buyer. en.bitcoin.it/wiki/Jercos gives his identity as Jeremy Sturdivant.
Pictures: heliacal.net/~solar/bitcoin/pizza/Thanks jercos!
www.thesun.co.uk/news/15049566/other-bitcoin-pizza-jeremy-sturdivant-fortune-hanyecz/ mentions Jeremy sold too early however:
The cryptocash disappeared when Sturdivant used it to "cover expenses" while travelling the US with his girlfriend.
Laszlo's secondary pizza event
. Source. web.archive.org/web/20210217220810/http://heliacal.net/~solar/bitcoin/lightning-pizza/ documents another pizza event, as we have different pizza boxes from the most widely known one: web.archive.org/web/20211219130004/http://heliacal.net/~solar/bitcoin/pizza/ Only image thumbs are archived however. web.archive.org/web/20211016070745/https://www.thesun.co.uk/news/15049566/other-bitcoin-pizza-jeremy-sturdivant-fortune-hanyecz/ however shows a large version that The Sun got their hands on before the takedown.
heliacal.net is presumably his personal website? But is was down as of 2023. But we have Wayback Machine archives of course :-) Latest working one of that page 2021: web.archive.org/web/20211219130004/http://heliacal.net/~solar/bitcoin/pizza/ And some other stalking:Laszlo is truly, literally, the nerd who got very very very lucky!!!

On June 12, 2010 Laszlo re-offers:and on August 4 user MoonShadow takes him up:but finally Laszlo withdrawls the offer:so we understand that the sales happened multiple times!!! Also, we understand that he was probably a miner.
This is an open offer by the way.. I will trade 10,000 BTC for 2 of these pizzas any time as long as I have the funds (I usually have plenty). If anyone is interested please let me know. The exchange is favorable for anyone who does it because the 2 pizzas are only about 25 dollars total, maybe 30 if you give the guy a nice tip. If you get me the upgraded extra large ones or something, I can throw in some more bitcoins, just let me know and we'll work something out.
Well I didn't expect this to be so popular but I can't really afford to keep doing it since I can't generate thousands of coins a day anymore. Thanks to everyone who bought me pizza already but I'm kind of holding off on doing any more of these for now.
TODO list all of the potential sales.

The original forum thread bitcointalk.org/index.php?topic=137.msg1195 suggests multiple purchases were made, until he had to withdrawl the offer. Perhaps an easier question is how many pizzas he got in the first place.
www.reddit.com/r/Bitcoin/comments/13on6px/comment/jl55025/?utm_source=reddit&utm_medium=web2x&context=3 mentions without source:One source is: bitcoinmagazine.com/culture/the-man-behind-bitcoin-pizza-day-is-more-than-a-meme-hes-a-mining-pioneer
I know. Laszlo Hanyecz estimates that he spent 100,000 BTC on pizza in 2010. Laszlo is the man that invented GPU mining and he mined well over 100,000 BTC.
Related thread from May 2023: bitcointalk.org/index.php?topic=5453728.msg62286606#msg62286606 "Did Laszlo Hanyecz exchange 40000 BTC for 8 pizzas, not 10000 BTC for 2 pizzas?" but their Googling is so bad no one had found the 100,000 quote before Ciro.
As per bitcoin.stackexchange.com/questions/113831/searching-the-blockchain-based-on-transaction-amount-and-or-date at blockchair.com/bitcoin/outputs?s=time(asc)&q=value(1000000000000),time(2010-05-18..2010-08-05) we can list all the transactions made between the offer and withdrawal dates for value exactly 10k. There are only about 20 of them, and including someone the 22nd of May, so it is extremely likely that this will contain the hits. No repeated recipients however, so it is hard to progress with more advanced analytics tools
Some of the transactions are:8 d1a429c05868f9be6cf312498b77f4e81c2d4db3268b007b6b80716fb56a35ad (29 May) is a common looking transaction with a single input from 1Bc7T7ygkKKvcburmEg14hJKBrLD7BXCkX and two outputs, one likely being the change to 1GH4dRUAagj67XVjr4TV6J9RFNmGYsLe7c and the other the actual value to 138eoqfNcEdeU9EG9CKfAxnYYz62uHRNrA.
- 49d2adb6e476fa46d8357babf78b1b501fd39e177ac7833124b3f67b17c40c2a (22 May 2010 06:17:59 GMT+1). This one has some Google mentions:This is a highly unusual transaction from a single address 17WFx2GQZUmh6Up2NDNCEDk3deYomdNCfk to a single address 1CZDM6oTttND6WPdt3D6bydo7DYKzd9Qik for the exact value with no change.By digging a bit, we see that the input comes from exactly 20 outputs, e.g. 1E43t1VCc3Q3STKauEiUoVqLbT81XT67xj, each of which is a block reward of 50 BTC, the reward value at those early times, thus satisfactorily explaining how the exact 10k value was obtained without change. Because we know that Laszlo was a big GPU miner, it is extremelly likely that this transaction was made by him.
- a1075db55d416d3ca199f55b6084e2115b9345e16c5cf302fc80e9d5fbf5d48d (22 May 2010 07:16:31 GMT+1) also has several Google mentions, e.g.:www.blockchain.com/explorer/transactions/btc/a1075db55d416d3ca199f55b6084e2115b9345e16c5cf302fc80e9d5fbf5d48d even specially marks it "Bitcoin Pizza" and "Notable". Furthermore, the receiving address 17SkEw2md5avVNyYgj6RiXuQKNwkXaxFyQ is even marked as verified an as belonging to Jeremy Sturdivant.Furthermore this also shows us how Jeremy then transferred about half of Bitcoins 10 minutes later, but we can't know if it was to his own accounts or to cash out.The nature of this transaction is very different from the previous one. It uses a bunch of inputs to a single address 1XPTgDRhN8RFnzniWCddobD9iKZatrvH4. 1XPTgDRhN8RFnzniWCddobD9iKZatrvH4 contains a mixture of regular small inputs, but also a bunch of block rewards e.g. www.blockchain.com/explorer/addresses/btc/1MUoh2nJudSDdKu9NkcevaCG1Qe3nZHWFZ, thus also clearly indicating Lsazlo ownership.
The input chain is complex, but it does contain one block reward on the third level: 17PBFeDzks3LzBTyt6bAMATNhowrvx5kBw + 79 rewards 4th level at 045795627ca29ec72a94c23a65ee775ea1949d60b6fba0938b75e1cfe1e6643e.

As for his lost password and inaccessible Bitcoin, Mr. Thomas has put the IronKey in a secure facility - he won’t say where - in case cryptographers come up with new ways of cracking complex passwords. Keeping it far away helps him try not to think about it, he said.
“I would just lay in bed and think about it," Mr. Thomas said.
Founded by Satoshi Nakamoto, making it the earliest and one of the most important Bitcoin communities. TODO official in any way? Who founded it?
Some notable appearances:
- in 2010, it is where Laszlo's pizzas offer was announced
- it was used e.g. on the Mt. Gox investigation: youtu.be/tJ-TsrK6SuY?t=2018
- Jimmy Zhong's investigation: youtu.be/pxvd1YOMGxU?t=1004
A lot of important development discussion happened in those channels: en.bitcoin.it/wiki/IRC_channels

Pinned article: Introduction to the OurBigBook Project
Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.
