I honestly believe that in stadiums law enforcement will be much more lenient than on the streets.
The world will all be looking at what happens on the pitch and in the stands, I'm sure Qatar, despite their conservatism, will not want to make a bad impression on the world.
However, I believe that the law will be strictly enforced on the streets and commercial establishments, so tourists will need to control themselves so they don't commit any bullshit that they may regret later.
We already started to see these issues and the world cup hasn't even started yet: A Mexican woman reported an assault in Qatar. She faces jail, 100 lashes.
"Although I had the forensic evidence of the beatings and everything, they believed him," Paola Schietekat said about the incident, which has made international headlines. I think we'll be hearing a lot of these things when thousands of foreign people arrive there. |

And you can of course write something into the coinbase of the block you found, just add this option to the config file: --btc-sig <arg> Set signature to add to coinbase when solo mining (optional) Do you know format of <arg> (such as HEX or plain text) or have example of working <arg>? I tried using search feature, but GitHub doesn't enable such feature on forked repository. It's a simple text argument, the same as the btc-address argument you have to give in the config file. Just add another line with that. Just try it out, that's the whole point of the testnet  |

~snip~ That's great to know! I wasn't aware of this rule. Will spin a Compac F up to mine some testnet BTC, then..  I've never hit a solo block, so this should be a pretty cool experience. That was the motivation for me to do this in the first place A couple of things you might want to do: Keep the log of your first block: sudo /home/user/bitcoin_testnet/cgminer/cgminer -c /home/user/bitcoin_testnet/mine_testnet.conf 2>> /home/user/bitcoin_testnet/my_first_block_log.txt And you can of course write something into the coinbase of the block you found, just add this option to the config file: --btc-sig <arg> Set signature to add to coinbase when solo mining (optional) |

A few blocks overnight? That means the testnet difficulty is extremely low. Exactly what was the testnet difficulty when you wrote this guide?
I'm sure this will help a bunch of people who are setting up testnet bitcoin mining farms.
The difficulty was in the millions: Network diff set to 76.6M But apparently testnet3 resets diff to 1 at some blocks, as those are the ones I hit: |

If you need some testnet bitcoins, you can easily get them by solo mining. Some other guides I've found in the web are outdated, so I made this one to work with the latest software/hardware. You'll need: - Latest version of Bitcoin Core(v23.0 at the time of writing)
- Special build of cgminer that allows solo mining, available from https://github.com/cmmodtools/cgminer with a small update from this guide.
- Ideally an ASIC miner. You can use any miner that works with cgminer, even the USB miner from GekkoScience, the Compac F:
To make things simple, for this guide I am going to assume you have two computers, one running a Compac F miner and another one running Bitcoin core. It shouldn't matter if you're running both on the same computer or if you have a different miner. Step 1: Install and run Bitcoin CoreWe're going to use the folder ~/bitcoin_testnet to save everything so that it's easy to remove once you're done and to keep things simple. You can of course use a different path if you want. Inside ~/bitcoin_testnet create a folder called data: mkdir -p ~/bitcoin_testnet/data Download the Bitcoin Core for your platform into ~/bitcoin_testnet/ and extract it there. Now let's prepare the configuration file. Create a text file named bitcoin_testnet.conf in ~/bitcoin_testnet/ and put these content in it: testnet=1
txindex=1
server=1
[test]
rpcport=5000
rpcallowip=YOUR_MINER_IP
rpcuser=YOUR_RPC_USER
rpcpassword=YOUR_RPC_PASSWORD
rpcbind=0.0.0.0
The thing that you need to understand here is that you're setting up the Bitcoin node to run in testnet, and you're defining an RPC port(5000 in this case, can be anything), user and password, and whitelisting a specific IP to connect to your node(YOUR_MINER_IP). You'll need these details and your Bitcoin node IP later when connecting from cgminer. You can now start running your Bitcoin node by doing the following(make sure to change user to your actual user: /home/user/bitcoin_testnet/bitcoin-23.0/bin/bitcoind -conf=/home/user/bitcoin_testnet/bitcoin_testnet.conf -datadir=/home/user/bitcoin_testnet/data If you want, you can keep this running in the background with screen: screen -dm -S bitcoin_testnet /home/user/bitcoin_testnet/bitcoin-23.0/bin/bitcoind -conf=/home/user/bitcoin_testnet/bitcoin_testnet.conf -datadir=/home/user/bitcoin_testnet/data You can then see what's happening with: screen -r bitcoin_testnet To detach the screen, simply press Ctrl-A and then Ctrl-D. You'll be back in the console, and the command will continue running in the background. Step 2: Install and run cgminerWe're going to use an updated repo of cgminer, this one has the latest changes from kano so that we can use the Compac F, plus some fixes that allow solo mining. Of course you might want to change the options to match your environment or miner. cd ~/bitcoin_testnet/
git clone https://github.com/cmmodtools/cgminer
cd cgminer
./autogen.sh
CFLAGS="-O2 -Wall -march=native -fcommon" ./configure --enable-gecko
make Now, in theory we should be ready, but we need one extra change. Open the file cgminer.c with your favorite text editor and change this line: if (opt_btc_address[0] != '1') {To this: if (opt_btc_address[0] != '1' && opt_btc_address[0] != 'm' && opt_btc_address[0] != 'n' ) {Basically we need to also consider the first symbol of the testnet address, which is either n or m. OK, now run make again: And now cgminer is compiled and ready. Let's create the configuration file: Create a text file named ~/bitcoin_testnet/cgminer_testnet.conf with these contents: {
"pools" : [
{
"url" : "http://YOUR_BITCOIN_CORE_IP:5000",
"user" : "YOUR_RPC_USER",
"pass" : "YOUR_RPC_PASSWORD"
}
],
"btc-address": "YOUR_TESTNET_BTC_ADDRESS",
"gekko-compacf-freq" : "400",
"gekko-compacf-detect" : true,
"gekko-start-freq" : "300",
"gekko-mine2" : true,
"gekko-tune2" : "60",
"suggest-diff" : "442",
"failover-only" : true,
}
If you don't have a testnet btc address yet, note that Bitcoin Core now doesn't generate a wallet by default any more so you will need to create one. You can read about it in createwallet. Then you should be able to getnewaddress. Make sure to use the legacy format as that's what cgminer is expecting. You address should start with n or m. Alternatively, you can simply use the GUI. To open the GUI, first stop the bitcoind process (Ctrl-C) and then run bitcoin-qt instead. There you'll be able to easily create wallets and generate addresses by clicking around. And now you can simply run cgminer like this: sudo /home/user/bitcoin_testnet/cgminer/cgminer -c /home/user/bitcoin_testnet/mine_testnet.conf You can of course also run it in the background with screen, or run this at startup, etc. It will depend on your particular setup. If you're on a pi for example, you could create a bash shell executable (~/start_mining.sh) with that code and then simply add this to /etc/rc.local: su - pi -c "screen -dm -S cgminer ~/start_mining.sh" That's just one example, you can choose to run it however you prefer. There it is, it should now say: Solo mining to valid address: YOUR_TESTNET_BTC_ADDRESS If you leave it overnight you should hit a few blocks with the Compac F USB miner. Happy testnet solo mining! |

I know that the Qataris are swimming in wads of money after the LNG prices went up by 20x during recent times. But at the same time, the players might find themselves in unfamiliar territory with a lot of restrictions. They can't go out with their friends to have a couple of beers. They can't even bring their girlfriends to the tournament, because unmarried couples are not allowed in Qatar. And more importantly, although the stadiums may be air-conditioned, we can't expect the players to stay there for 100% of the time.
Absolutely. I don't think it would be a nice place to live if you're not allowed to do most things that are considered normal in your own country. And the penalties for these things are really harsh, years of imprisonment for drinking a beer in public. |

~snip~ It's never late to join the "Bitcoin party". The cryptocurrency constantly evolves, so it's hard to catch up with the latest developments on the industry. Those who get in now will be considered early adopters in the future. I'd say Bitcoin still hasn't reached the mainstream, even though its more popular than it was in its early days. Many experts have predicted a Bitcoin price of $1m in the future. Besides, there are a lot of countries that are yet to approve Bitcoin as legal tender (or use it officially as an alternative to Fiat). It's hoped that El Salvador's move will encourage other countries to do the same. Once the world embraces Bitcoin as an alternative to Fiat, then "hyperbitcoinization" will be realized. Early adopters like us will surely become filthy rich if that happens. Bitcoin is just starting to blossom so I'd suggest anyone to buy it at a cheap price before it's too late. Just my opinion  There's already two countries in which Bitcoin is legal tender, El Salvador and Central African Republic. This seems like a bit of a race against countries making CBDCs legal tender, like Bahama's Sand Dollar, Jamaica's Jam-Dex, and Nigeria's eNaira. |

You sent your bitcoin to another address not controlled by you, so you can't have them back. If you want to get some help about how to get the altcoin you're expecting, you should post this in the altcoin forum: https://bitcointalk.org/index.php?board=67.0 |

Where I live it wouldn't be a big deal if a, let's say, a student saw me in a casino. Professional groups like teachers, doctors, or lawyers don't make a big deal out of it since it's legal. If they saw me in a brothel it would be pretty much the same. Maybe if they saw me in a brothel and I had a wife it would become an popular rumor, but they wouldn't fire me because of it.
In modern societies gambling is seen more like smoking. Many people don't smoke and don't like smokers but you don't fire people because they're heavy smokers.
Sure, you probably won't get fired, but the relationship with your students might be different after they see you. They had an idea in their heads and then seeing you there, or smoking, etc, changes that perception. I'm not saying it's necessarily a bad thing, but they will see you differently. |

You should sleep on Netherlands, they may not be looking like favorites here, but the reality is that they have a great path to be a good team for a while. First they have an easier group than most, then if they finish first then they will face the second of another group which could be a worse team again, and then they will face the team who beats the other one which is understandable and quarter finals would be harder but that's a good path to take, a few good lottery and you get yourself an easy way to go.
I believe that they are not the contenders right now but they are also not a horrible team neither that could end up in finals.
Yeah, that's kinda what I think might happen. It's basically a strong team, that with a bit of luck in a couple of matches could actually end up winning the world cup. If you compare it with weaker teams like Qatar for example, I don't think they would be able to win, even if they get lucky a couple of times. |

I still don't understand why the Portuguese coaches choose to start Ronaldo when they can give better opportunities to the younger players in the squad who are hungry in front to prove themselves before the world cup to boost their confidence. Ronaldo is still a great player but we all know that he's not in his prime and for Portugal, it will not be in their best interest to depend on him during the world cup. Ronaldo should still be in the squad but should have reduced playing time to give opportunity to other younger players especially since he's going into retirement soon and they will need younger players to carry the National team forward.
There's no chance that Ronaldo will not play the entire 90 minutes really. There's so much pressure from everyone to see him play. I don't think they will put any younger player instead of him, specially since this will probably be his last appearance in the world cup. |

Yeah and I think he is the era of rising Pete Sampras and Andre Agassi so it might have been difficult for him to maintain that number one spot. And along the way there are great players in that era, and yet Sampras and Agassi are the two rivals that maintain their rivalry inside the tennis court until the arrival of Roger and then Rafa to continue what they have started. So it's really hard to debate as to who is the best or the greatest.
Absolutely right, Marcelo Rios actually took the number one spot from Pete Sampras who otherwise would have continued to celebrate his 7th consecutive year as number one. |

~snip~ I don’t expect Netherlands to be a favourite, even if the odds look decent I strongly feel that they’ll crash out without making it to the semis. Furthermore Brazil squad is covered exceptionally well in each and every department and I just don’t see any other team beating them, and thus if one can get decent odds on Brazil I feel that they should take their chances and stick with Brazil only during this tournament. Yeah, absolutely right. It's just a personal thought that I've always seen the Netherlands so close to winning, but never actually achieving it. I don't think they have a squad worth of winning, but you never know. Football is full of surprises, and that could be a nice one. |

On the other side of things, I think Marcelo Rios must have been the person with the shortest amount of time as number one in the world, he retired very shortly after |

You're a professional like a lawyer or a teacher in a respected university, will it harm your reputation if people around you or your students discover that you are into gambling, you're not really a compulsive gambler but gamble for entertainment, how will you explain this to people around you or will you explain to protect your reputation or just ignore them.
Privacy is important. Every person has many different aspects to them, and each person can decide what to show to different people. For example, you will behave in one way with your family and in a different way with your employees, customers, or boss. The students in this case shouldn't know your private life, which includes gambling. That way you don't have to explain it to anyone other than yourself. |

Nice little machine.
I'm running my Apollo with an old Linux desktop on Turbo mode and get about 3 TH.
Although not recommended, anyone tried to run it faster?
Yeah, I've run it faster than Turbo using a power supply with more watts than the "official" one. It's a bit of diminishing returns really, I got around 4TH for a bit but the fans were just incredibly loud and the heat was a lot more than normal. At that point might as well use an industrial miner for much better results. I'm now actually running it extremely quiet (internal fan not moving plus a silent noctua fan on top) and it's mining at 1-1.5 TH. It can actually go to 2-2.5 TH with minimum noise but I prefer it basically noiseless. |

Who do you think is the best number one of all time?
Pete Sampras, Jimmy Connors, Andy Murray, Novak Djokovic, Roger Federer, or Rafael Nadal? (maybe another one?)
Sampras still has the impressive record of being the number one player for 6 continuous years.

The coach of Brazil is very bad (he plays in a 4-2-2-2 formation, the most ridiculous formation I have ever seen). Brazil is the best team in terms of squad quality, but a Germany that implements a proper system will wipe them out on the field. Brazil's process will only look at individual talent in this tournament. So whether they beat Germany or not, Argentina will reach the final from that side.
I expect(not want) France to be in the final at least, maybe even win the cup. There is also a decline in France, this is clear, but France is much better in terms of squad quality and the game they play is very clear, their midfield is monstrous, and in the world cup, when physical strength is combined with technique, they will reach the finals very easily, whether they face Spain or Portugal or not. We also know that Mbappe and Benzema will give their best for the ballondor race.
I'm not sure, France is not the same as it was when they actually won the World Cup. I hope the Netherlands wins this one, even though it's going to be a tough one. Brazil, Argentina, Spain, and many others have such amazing squads, we'll have to wait and see what happens. Also I reckon the hosts are not going to make it to the next stage even though there's going to be amazing celebrations prepared for them. |
