Note that I removed Benson Samuel as moderator, but only because I view the situation as potentially too much of a conflict of interest. I have no reason to doubt Benson Samuel's character.
162  Other / Meta / Re: Any issue with two accounts sharing the same computer(IP) ? on: April 11, 2018, 01:04:58 AM
Can you please provide any examples of this happening in the past? I am curious about this, because if this is the case then it would seem to a hazard to use public/shared VPN(s), TOR nodes or anything like that. I don't believe that they simply would ban an account because it shares an IP with an offender. Otherwise, paying a fee for an "evil" IP would probably not be implemented, either.

I want to read up on some more official statements surrounding this issue.

You won't be automatically banned if someone on the same IP is banned. IP addresses are pretty poor identifiers. In certain countries it is very common for different people in the same general region to share IPs a lot, and even two veteran forum users in the same US state are quite likely to share an IP address somewhere in their IP history.

But if you evade a ban, your alts will eventually be found through manual investigation.

Yep! If I may ask,what is the other field adjacent to the merit input?

Read the HTML and find its name.

The last one is your session key, which allows anyone to use your account. Congrats. (I logged you out, invalidating it...)

Hidden form fields are extremely common. You'll find them on virtually every form on the forum. They're hidden from view, not "secret".
167  Other / Meta / Who is able and willing to moderate the Politics & Society section? on: April 10, 2018, 07:18:55 AM
Politics & Society is trash. People go there, look at a headline, and post a few sentences of their first gut reaction without reading any of the other replies. Who here is up to the task of moderating the section in order to remove this garbage, but without hampering the free exchange of ideas there? It'll be tough, since I do want to hear the thoughts of people who can't speak perfect English, people with extreme/offensive ideas, people who are rude while still making legitimate points, etc. So it'll be a difficult balancing act.

Post in this thread if you're interested so I can see other people's comments on you.

169  Economy / Auctions / Advertise on this forum - Round 241 on: April 09, 2018, 07:18:41 PM
The forum sells ad space in the area beneath the first post of every topic page. This income is used primarily to cover hosting costs and to pay moderators for their work (there are many moderators, so each moderator gets only a small amount -- moderators should be seen as volunteers, not employees). Any leftover amount is typically either saved for future expenses or otherwise reinvested into the forum or the ecosystem.

Ads are allowed to contain any non-annoying HTML/CSS style. No images, JavaScript, or animation. Ads must appear 3 or fewer lines tall in my browser (Firefox, 900px wide). Ad text may not contain lies, misrepresentation, or inappropriate language. Ads may not link directly to any NSFW page. No ICOs[1], banks, funds, or anything else that a person can be said to "invest" in; I may very rarely make exceptions if you convince me that you are ultra legit, but don't count on it. Ads may be rejected for other reasons, and I may remove ads even after they are accepted.

There are 10 total ad slots which are randomly rotated. So one ad slot has a one in ten chance of appearing. Nine of the slots are for sale here. Ads appear only on topic pages with more than one post, and only for people using the default theme.


- Your ads are guaranteed to be up for at least 7 days.
- I usually try to keep ads up for no more than 8 or 9 days.
- Sometimes ads might be up for longer, but hopefully no longer than 12 days. Even if past rounds sometimes lasted for long periods of time, you should not rely on this for your ads.


Exact historical impression counts per slot:

Info about the current ad slots:

Ad blocking

Hero/Legendary members, Donators, VIPs, and moderators have the ability to disable ads. I don't expect many people to use this option. These people don't increase the impression stats for your ads.

I try to bypass Adblock Plus filters as much as possible, though this is not guaranteed. It is difficult or impossible for ABP filters to block the ad space itself without blocking posts. However, filters can match against the URLs in your links, your CSS classes and style attributes, and the HTML structure of your ads.

To prevent matches against URLs: I have some JavaScript which fixes links blocked by ABP. You must tell me if you want this for your ads. When someone with ABP and JavaScript enabled views your ads, your links are changed to a special randomized URL which redirects to your site when visited. People without ABP are unaffected, even if they don't have JavaScript enabled. The downsides are:
- ABP users will see the redirection link when they hover over the link, even if they disable ABP for the forum.
- Getting referral stats might become even more difficult.
- Some users might get a warning when redirecting from https to http.

To prevent matching on CSS classes/styles: Don't use inline CSS. I can give your ad a CSS class that is randomized on each pageload, but you must request this.

To prevent matching against your HTML structure: Use only one <a> and no other tags if possible. If your ads get blocked because of matching done on something inside of your ad, you are responsible for noticing this and giving me new ad HTML.

Designing ads

Make sure that your ads look good when you download and edit this test page:
Also read the comments in that file.

Images are not allowed no matter how they are created (CSS, SVG, or data URI). Occasionally I will make an exception for small logos and such, but you must get pre-approval from me first.

The maximum size of any one ad is 51200 bytes.

I will send you more detailed styling rules if you win slots in this auction (or upon request).

Auction rules

You must be at least a Jr Member to bid. If you are not a Jr Member and you really want to bid, you should PM me first. Tell me in the PM what you're going to advertise. You might be required to pay some amount in advance. Everyone else: Please quickly PM newbies who try to bid here to warn them against impersonation scammers.

If you have never purchased forum ad space before, and it is not blatantly obvious what you're going to advertise, say what you're going to advertise in your first bid, or tell me in a PM.

Post your bids in this thread. Prices must be stated in BTC per slot. You must state the maximum number of slots you want. When the auction ends, the highest bidders will have their slots filled until all nine slots are filled.

So if someone bids for 9 slots @ 5 BTC and this is the highest bid, then he'll get all 9 slots. If the two highest bids are 9 slots @ 4 BTC and 1 slot @ 5 BTC, then the first person will get 8 slots and the second person will get 1 slot.

The notation "2 @ 5" means 2 slots for 5 BTC each. Not 2 slots for 5 BTC total.

- When you post a bid, the bids in your previous posts are considered to be automatically canceled. You can put multiple bids in one post, however.
- All bid prices must be evenly divisible by 0.02.
- The bidding starts at 0.02.
- I will end the auction at an arbitrary time. Unless I say otherwise, I typically try to end auctions within a few days of 10 days from the time of this post, but unexpected circumstances may sometimes force me to end the auction anytime between 4 and 22 days from the start. I have a small bias toward ending auctions on Fridays, Sundays, and Mondays.
- If two people bid at the same price, the person who bid first will have his slots filled first.
- Bids are considered invalid and will be ignored if they do not specify both a price and a max quantity, or if they could not possibly win any slots

If these rules are confusing, look at some of the past forum ad auctions to see how it's done.

I reserve the right to reject bids, even days after the bid is made.

You must pay for your slots within 24 hours of receiving the payment address. Otherwise your slots may be sold to someone else, and I might even give you a negative trust rating. I will send you the payment information via forum PM from this account ("theymos", user ID 35) after announcing the auction results in this thread. You might receive false payment information from scammers pretending to be me. They might even have somewhat similar usernames. Be careful.

[1]: For the purposes of forum ads, an ICO is any token, altcoin, or other altcoin-like thing which meets any of the following criteria: it is primarily run/backed by a company; it is substantially, fundamentally centralized in either operation or coin distribution; or it is not yet possible for two unprivileged users of the system to send coins directly to each other in a P2P way. The intention here is to allow community efforts to advertise things like Litecoin, but not to allow ICO funding, even when the ICO is disguised in various ways.

9 @ 1

If you are not a Jr Member and you really want to bid, you should PM me first. Tell me in the PM what you're going to advertise.
If you have never purchased forum ad space before, and it is not blatantly obvious what you're going to advertise, say what you're going to advertise in your first bid, or tell me in a PM.

4 @ 0.2

Theymos, can you please check PM from me and tell if ETH.TOWN is eligible for advertising.

Too ICO-like for now; see my PM.

2 @ 0.26

You also seem to be advertising ETH.TOWN.

1 @ 0.28

I still think that's too ICO-like.

 - Cobra has ultimate control over the domain name. I have access to the domain name settings.
 - Cobra runs the server.
 - Will Binns holds the BTC.
 - Cobra has ultimate control over the domain name. I have access to the domain name settings.

I am not Cobra. What would even be the point of that?

It looks official but why it's inactive since 30 Nov 2017?

This can be helpful for announcements or any such unforeseen events.

That is the official twitter handle, but I only tend to use it for long-lasting outages that I can't quickly fix. I don't use Twitter otherwise, so you're not going to see any more regular news, etc. from there.

Is * actually used for anything? I don't recall ever using a subdomain on the forum. is the image proxy.

 - Prior to last year, and used *, while used its own cert.
 - As of last year (which I'd forgotten about), and use *, while uses its own cert.

Those were the good ole days like when Atlas tried to commit suicide and I sent the police to his home to make sure he's okay.

I also called his local police when he did that, but they basically blew me off. Did you actually convince them to visit him?

Surprised nobody pointed out the pointless bit shifting in that equation Wink

I did write it that way in part to be more confusing, but it's not pointless; 1<<10 is 2^10. It restricts the result to the 10-bit space of the game-of-life board.

177  Other / Meta / TLS error on: April 08, 2018, 03:19:12 AM
Sorry about the TLS error downtime. What happened was that I used to have separate certs for and *, but I forgot that I combined them last time, so when I renewed *, I didn't update the certificate on the server. And I have Cloudflare's strict TLS enforcement enabled, so it just killed the connection as soon as it expired.
178  Other / Meta / Re: need urgent support for activate cooper member,any admin please support me on: April 06, 2018, 08:45:06 AM
It's just bitcoind + about 200 lines of code. BitPay and Coinbase are only (maybe) useful if you need a guaranteed USD value right away when someone pays you. If you're willing to accept a little exchange-rate risk, I highly recommend handling payments yourself.

Until very recently, I was using the bitcoind accounts pattern (getaccountaddress & getbalance) recommended from about 2011 to 2014. But this has been deprecated for a few years, and it seems to be broken in 0.16. In order to quickly work around the 0.16 bug, I switched to the one-address-per-user anti-pattern (getaddress -> put this address in your database for the user -> getreceivedbyaddress) which you should really not do because it involves address reuse. (But the forum's case of reusing addresses once or twice isn't the end of the world, which is why I'm accepting it for now.)

I haven't decided yet how I'll handle payments in the long-term. Bitcoind-accounts were kind of nice in how they handled payments as user balances rather than invoices. It allows for easier, closer integration with your site, I think, and it makes it easier to think about a lot of edge cases. It wouldn't be all that difficult to basically re-implement bitcoind-accounts on my end so as to keep things roughly as they are while avoiding address reuse.

On the other hand, I feel like the ecosystem is mainly moving in the direction of invoices rather than balances. Bitcoind's development seems to be focused on that use-case, and LN fits far more naturally into an invoice-based system. For this, I'd be inclined to switch to BTCPay (which will support LN when possible), but that'd require a total rethink and rewrite of my payments code.


If you want an invoice-based system similar to PayPal, Coinbase, or BitPay, or if you want to be more future-proof, use BTCPay.

If you want to do what the forum does and deal in user balances rather than invoices, it's pretty easy to use bitcoind directly. Something like (pseudocode):

# you have a SQL table `addresses` with columns user, time, address
# and a table `spends` with columns user, time, amountSpent

def getAddress(username):
address = sqlQuery("select address from addresses where user=% order by time desc limit 1", username)
if address is null or bitcoindQuery("getreceivedbyaddress % 0", address) is not 0:
address = bitcoindQuery("getnewaddress")
sqlQuery("insert into addresses values (%, NOW(), %)", username, address)
return address

def logUserSpend(username, amount):
sqlQuery("insert into spends values (%, NOW(), %)", username, amount)

def getBalance(username, minConfirmations):
balance = 0
for address in sqlQuery("select address from addresses where user=%", username):
balance += bitcoindQuery("getreceivedbyaddress % %", address, minConfirmations)

totalSends = sqlQuery("select sum(amountSpent) from spends where user=%", username)
return balance - totalSends

# The above is conceptually how you do it, but you may want to
# add something to avoid so many calls to bitcoindQuery, which is
# a slow operation. As written, this doesn't scale to hundreds of
# addresses per user. For example, you may want to store balances
# for old addresses and assume that the user will not reuse them,
# or poll bitcoind's listsinceblock looking for addresses for
# whom you should update the balances in your database.

def exampleBuyItem(phase, user):
if phase is entry:
print "Please pay to %", getAddress(user)
elif phase is registerPayment:
sqlQuery("set transaction isolation level serializable")
sqlQuery("start transaction")
if getBalance(user, 6) >= price:
logUserSpend(user, price)
print "Not enough money"
179  Other / Meta / Re: Are you ready for 2,000,000? on: April 03, 2018, 06:24:50 PM
You appear to have also misread my point.

The data on UID's is different than the data on this forum's stats page:

Why is that number lower than 2000000?

In the forum's first couple of years, accounts would sometimes be deleted. Also, in rare cases an ID can be skipped (eg. if a database transaction gets rolled back).
180  Other / Meta / Re: Implement proof-of-work CPU altcoin mining instead of CAPTCHA on: April 02, 2018, 09:06:47 PM
Using a PoW is something that I've thought about as an optional alternative to the captcha, though there's no need for it to actually do any altcoin mining.

Captcha-solving services charge about $0.003 per reCaptcha solve currently, so the computation cost to an attacker (not an average user) would have to be comparable to that. Certainly this makes SHA-x PoW impractical, as it would be far cheaper for an attacker using GPUs/ASICs and special code vs an ordinary user solving it via JavaScript on a CPU. Maybe cuckoo would work.

Another thing I've thought about is selling transferable blinded bearer certificates which could each be burned to solve 1 captcha.

But both of those would require significant development. If someone codes up the necessary libraries and end-user utilities, I would be very keen to use it on the forum, but I'm not going to create them (at least not anytime soon).

More realistically, I might sell one-time-use captcha-bypass codes at $3 per 1000 or something like that. This wouldn't be as flexible as blinded bearer certificates, but it might be sufficient.

Someone could right now write a userscript which integrates the forum captcha with a captcha-solving site. Some of them allow you to purchase captcha solves, solve captchas in exchange for credits (eg. solve on your computer and then use the credits on a mobile device), or transfer credits between accounts (eg. buy credits from other users). This is still not ideal from a privacy standpoint, of course.
