1  Economy / Collectibles / [AUCTION] Casascius 2013 0.5BTC, loaded, with certificate and hash in blockchain on: September 07, 2017, 03:13:49 PM
What I am selling

I am selling a Cascascius 2013 0.5BTC coin.

The coin is loaded (so you can get the BTC but also some alts like Clams for instance).

I bought it in this auction, on this forum, back in the days in 2013:

The seller at that time, molecular, included a certificate of existence. I have a high-resolution digital picture of this coin, whose hash was included in the blockchain on the 31th of May, 2013, proving the existence of this very coin and that it is a real Casascius*. I will send this digital picture of the certificate to the buyer of the coin.
*: Molecular and his partner messed up the certificates themselves, and this certificate mentions the hash of another coin sold at the same time. Nevertheless the actual, correct hash of the picture of this coin is indeed included in the same transaction as mentioned on the certificate, so the important part is correct.

You can see pictures of this beauty here:

Given my trust record, I don't want to bother with escrow. By bidding you accept to send BTC first, then I'll send the coin with a tracking number via UPS or Fedex (or equivalent). Sending fees is on me, up to 200$, so please take that into account when you bid.

Auction conditions

Starting price is 0.6 BTC. Bid increment by 0.01 minimum.
Auction runs until the end of this Sunday, 10th of September. Any valid bid adds 15mn to the deadline.
Happy bids!
2  Bitcoin / Bitcoin Discussion / THE RISE AND RISE OF BITCOIN - How to get perfectly sync subtitles on vimeo on: October 12, 2014, 01:49:00 PM
I bought the documentary and wanted to watch it with people that are not so proficient in English. The subtitles are off by ~2 seconds (too early), which is pretty annoying and gives a torrentish taste of "not comfortable watching" even though I paid 13$.

I found a workaround to better sync them, I think it exploits a bug in vimeo and should be reproducible with any browser. Works at least on firefox 32.0.3, linux.

Assuming you bought the movie and have access to it on vimeo:

1) go to this direct link:

2) Choose your subtitles by clicking on "CC"

3) Start the movie

4) Immediately when it starts (after X seconds), click on "vimeo" link (bottom right). It will open the video in another tab

In this new tab, the subtitles will be delayed by X seconds (this is where it looks like a vimeo bug), so if you did step 4) when the movie was at ~2s, they should now be perfectly in sync.
Hope that helps!  Smiley

PS: It would be much better if we could get access to srt files to watch the mp4 video offline with subtitles. If anybody from the documentary team is reading this, you know what to do!
3  Other / Meta / Suggestion: click on "watched" threads should not bring you to first page. on: September 26, 2014, 12:51:32 PM
I find it a waste of time everytime I click on my "watched" threads in the watchlist, to always arrive on the first page of the threads.
One possible consequence also (not sure if there are any kind of condition/filter for this), is that it increases the "view counter" twice (one for first page, then one for later page of interest) everytime somebody go to a thread through the watchlist.

When threads are watched by a given user, it assumes the user knows about them already, and is interested in following the new stuff that will come in the future.
So I think ideally it should point directly to the first post not read by the user. I assume the relevant post is accessible somehow in the DB, since the watchlist mechanism is able to tell you when there is a new post in a thread, therefore it knows which last post you've read there.
If it is not possible, it should point to the latest post of the thread, this would be at least more often correct (ie, what the user wants to read) than the current mechanism.

--------------------------------- Rules ---------------------------------

contest period = between the 27/06 23h59 (UTC) and the end of the world cup (end of the final game).

Choose your team and become a supporter!

Subscribe your bitcoin address to your favorite team (who you think will win the world cup). To do that send something to the corresponding address. (The amout doesn't matter, so send the minimal one, we just need one transaction from your address!).

That's everything you have to do! Have fun on LuckyBit and cheer for your team.
All your bets will then increase your part of the prize in case your team wins (see below)


How do we select winners and split the prize

At the end of the world cup, the supporters of the winning team will share the 5BTC prize. It will be split among them based on the volume they wagered on LuckyBit during the contest period, and when did they choose the winning team. Those that chose the team earlier will have a bigger part of the prize.

More precisely, if you chose a team n days before the final, your amount will be multiplied by n+1 to determine your part of the prize.

Alice, Bob and Charly are the three supporters of France, and France wins the world cup.

Alice has wagered 1BTC on LuckyBit during the contest period, Bob 4BTC and Charly 5BTC.
Alice chose France very early, 15 days before the day of the final game. The amount she wagered is multiplied by 16 (her "earliness advantage").
Bob chose France also quite early, 9 days before the final day. His amount is multiplied by 10.
Charly has been supporting another team, until that team lost (Charly was sad). So he switch to France only 2 days before the final. His amount is multiplied by 3.

The total multiplied amount is then:
(Alice_amount * Alice_multiple) + (Bob_amount * Bob_multiple) + (Charly_amount * Charly_multiple) = (1 * 16) + (4 * 10) + (5 * 3) = 71
The share of Alice would be: (Alice_amount * Alice_multiple) / Total_multiplied_amount = 0.225
The share of Bob would be: (Bob_amount * Bob_multiple) / Total_multiplied_amount = 0.563
The share of Charly would be: (Charly_amount * Charly_multiple) / Total_multiplied_amount = 0.211

The prize of 5BTC would then be splitted according to their share of it (1.125BTC to Alice, 2.815BTC to Bob and 1.05BTC to Charly).

TL;DR: the more volume you play on LuckyBit, and the earlier you choose the team, the more you get at the end if the team wins.

Some notes

- LuckyBit doesn't act as a broker. The contest is free for everyone to participate. The 5BTC are from our own pocket.
- If you choose a "small" team early, you will probably get more in case they win! You might even keep the most part of the full 5BTC if you are an early adopter of that team. Wink
- Feel free to post here once you've become a supporter, and join us on the LuckyBit chat!
- Icing on the cake: this giveaway is provably fair Smiley

Good luck everybody, ask if something is unclear!

Post here your technical questions, your pools or mining softwares announcements and updates.


Spread around the hashrate! Join the smaller pools to improve network health.
Larger pools can only reduce your variance, but on average you get less than on small pools due to ddos-attacks, higher fees, downtimes and slower hashing modules

Only open-source pools are mentioned, sorted by donation then fees. Fees include the donation, so miners won't pay more than the fees listed on the "fees" column. Misleading advertisement = undetermined ban ("undetermined" doesn't mean "forever", just "as long "as we deem it necessary"). Manager's note is a list with 100 character max, no exclamation points and no links. For updates, please contact Quanttek (same on IRC)
Beware: we are doing our best to stay current regarding fees, but always double-check on the pool itself.
We recommend to use only the bolded pools, which are up-to-date on important updates and security fixes. (When none are bolded, all are up-to-date)

Je suis l'un des deux créateurs/programmeurs/opérateurs du jeux LuckyBit, je crois pas qu'il soit tellement fréquenté par des francophones, je vais donc faire un petit bump ici Smiley

Depuis ~3 semaines on a lancé un "chat-lotto" qui a un certain succès ! En venant simplement chater sur le site (vous n'êtes même pas obligé de jouer), vous pouvez être tiré au sort par le chatbot régulièrement (toutes les quelques minutes), et gagner des sommes significatives. Ca va de 0.0008 à 0.1 BTC, c'est nettement plus que les "faucets" (ou pire les trucs où vous devez regarder des pubs) que certains essaieront de vous vendre...

Le chat est super relax, et on peut discuter de tout (autre sites de jeux, mining, etc...) donc pour peut que vous puissiez écrire un minimum d'anglais, n'hésitez pas à venir faire un tour !

10  Economy / Games and rounds / ➫ ➬ ➫ ➬ LUCKYB.IT [one week lottery] win a collector ASIC miner AND up to 1 BTC on: January 27, 2014, 03:33:51 PM
The new LuckyBit promo (for one week):

Collector USB miners lottery

Win a collector ASIC miner by playing LuckyBit!

You can now win a laser-engraved collector’s ASICminer Blockerupter USB miner by playing LuckyBit.

This edition has been engraved with the LuckyBit logo.  We only engraved very few of them, so this is definitely a rare item. They are new, functional, and will be delivered in original plastic boxes.

In this lottery, we are giving away a total prize money of 1.0 BTC:

  • 1x Prize 1: 0.5 BTC and 1 collector’s miner
  • 2x Prize 2: 0.1 BTC and 1 collector’s miner
  • 3x Prize 3: 0.1 BTC

How to participate:

Play a valid bet on between Monday, 27/01/2014 at 15:00 and Monday 03/02/2014 at 23:59:59 to participate in the lottery. Times are UTC (as on LuckyBit).

  • 6 winners are selected randomly from the list of all valid bets in a provably fair manner.
  • From the list of 6 winners, the bet with the higher amount gets the better prize.
  • Ties are resolved by comparing the last 4 characters of the transaction hash (higher -> better prize).

For example, if the list of winners are:

  • bet amount 0.001 BTC -> Prize 3
  • bet amount 0.01121 BTC -> Prize 3
  • bet amount 0.01 BTC -> Prize 3
  • bet amount 0.03212 BTC -> Prize 2
  • bet amount 0.1 BTC -> Prize 1
  • bet amount 0.04 BTC -> Prize 2

These 6 winning bets will be selected among all bets of that period, which means: If you play more, you have a better chance of winning. Of course your address(es) can be selected multiple times if you made several bets.
And if you play higher, you have a better chance of winning prize 1.

Technical info on how we select the list of winners in a provably fair manner:

  • take the hash of the first block listed on with a timestamp after Monday 03/02/2014 (23:59:59)
  • take the list of all (valid) bets between 27/01/2014 (15:00) and Monday 03/02/2014 (23:59:59)
  • use the last 4 characters of this hash to retrieve a 1st bet from this list by converting it into a number and taking the modulo (for programmers: list.get(hash[:-4] % list.length) )
  • use the last 4 characters of this bet's transaction id to get the next winning bet in the same manner
  • repeat until 6 winning bets are found
  • sort list using criteria described above

Note that you need to be able to sign a message to prove you own the selected address if you are one of the winners.

Please note that these ASIC collector’s miners are promotional gifts and are intended as a collector/souvenir. Due to the extreme increase in mining difficulty, you cannot expect to mine a substantial amount of Bitcoins with them. Nevertheless, the miners are fully functional (actually brand new) and can be used for pool- or solo-mining.

For any question or remark on the game, see our main thread here:

Good luck to all!

They are all brand new, in their plastic boxes, grouped in cardboard boxes by 10, from AM factory. Never used, boxes are not open, perfect for resellers.
If you need more technical info on the items see here:
(all the 100 are silver ones)

Only one auction winner
I am not going to split the lot and send multiple packages. Instead the auction is for all the 100 together. Bid accordingly.

Free shipping
I will send it from Europe.
Shipping (with tracking number) is included in your bidding. I will post the package the day after the end of the auction, I estimate the shipping to take 1~2 days for Europe. I am willing to spend about 1BTC for shipping, so if you live on the other side of the world it might not be the best auction for you.  Smiley

Auction will end in one day, 24 hours after this OP.

I would prefer to go the trustful way, but I am ok if you want to use an escrow (I would accept John K or TAT), but you'll have to organize everything.

Starting price, minimum bid increment
Starting price is 4BTC.
Min increment is 0.1BTC

Happy bidding!  Smiley

Imagine being in a bar, a party, or any social event full of people, some that you know more or less, many unknown.

Imagine that everybody constantly bump into each other because they all have one arm straight in front of them, with the hand like if they were begging for something. They would have only one hand remaining to actually do other things like drinking a beer, hugging friends, and so on. And before starting any conversation with another person they just meet, most of them would ostensibly put this open hand in front of their interlocutor. You would probably find weird to see all these palms in front of the faces of each other, but that would be probably because you'd be new in the place, as all the people around would act as if it was normal behavior.

When curiosity would get too strong, you'd start asking few people around you: "why do you keep your hand in front of you like that? That's not very practical, what's the purpose?".

And invariably, you'd get similar answers from all of them: "so if I was helpful in the discussion, you can reward me!", "hey! I've been nice to you? Drop me few cents!", or simply "Hey nice to meet you, give me a tip!". Often with a smile like this:  Smiley

Do I have to add that I don't get this thing with signatures? Do you act like that in real life? Very few people actually get "tips" here, and these people are really bringing something. When the first action of somebody with a new account is to copy this, it's very, very laughable to me.

19  Bitcoin / Development & Technical Discussion / bitcoind RPC calls: get fee amount of received transaction on: July 07, 2013, 10:40:12 PM
Dear all,

I don't find a convenient way with bitcoind rpc calls, to determine the fee amount of a transaction I receive.
I found the information on the wiki to be wrong or outdated on this:
'gettransaction' is said to return the fee, but I found that it is true only for transaction of type "send", not "receive".

Maybe there is another place where I can find more reliable info on the bitcoind RPC calls?

To get this fee amount, I would like to avoid looping over vin and vouts to compute the difference of the sums, there must be something easier! Am I missing something?

Not bitcoin specific, but interesting read as bitcoin is a good fit for this "space money". Also it's about paypal which is both a "competitor" of bitcoin and also has expressed interest into bitcoin.

Bitcoin would be perfect for this! Knowing how close paypal is following the bitcoin technology and growing economy, I'm sure they know that. Smiley
