1101  Other / Meta / Re: Bitcointalk BBCode New Feature - The Hobbit Header! on: June 20, 2015, 01:50:17 AM
BBCode is closest to HTML, so it makes the most sense when doing complex things like tables (or any sort of block element like [code], [center], etc.). I prefer markdown or wiki syntax when doing more simple things like emphasis, links, and lists, though. The biggest thing I hate about markdown is that it doesn't work well with newlines; oftentimes you need to separate things by extra newlines (or two spaces after the end of a line) for them to work properly, which is annoying.

The live character count isn't quite accurate. For example, each newline is actually two characters, but the live count counts it as only one character. So if you have "11 characters left" in 56 lines, then you're actually going to be at least 44 characters over the limit. Fitting things to the limit requires some trial and error. In this case, it might work to just remove the unnecessary newlines from your signature.

Your signature was cut off before, but you didn't notice this because the forum tried to fix your incomplete bbcode and was apparently mostly-successful. To prevent the bbcode parser from generating invalid HTML (which was causing trouble), this is no longer done in some cases. It's not going to be changed. You'll have to fix your signature.
1103  Other / Meta / Re: Bitcointalk BBCode New Feature - The Hobbit Header! on: June 19, 2015, 01:45:36 AM
OK, I "fixed" it. Your post will parse to an error message if your table code is seriously messed up like this. Don't freak out if a long post disappears due to this -- it'll all still be there when you go to edit it.

theymos, I know that the BBCode parser in FluxBB disallows invalid BBCode. Can't you check if there is an option for that in SMF (or if you can make one)? Might be something worth checking out.

That's not supported in SMF because:

Also, I doubt it's a bug, to parse a tree all you need is a stack.

SMF's bbcode parser is ad hoc, not using any standard parsing method. It doesn't create an AST, even conceptually. So it's incapable of properly detecting syntax errors.
1104  Other / Meta / Re: Bitcointalk BBCode New Feature - The Hobbit Header! on: June 18, 2015, 04:42:20 PM
Please don't actually do this. It looks terribly messy and exploits invalid HTML that will vary per browser. We will be deleting posts that do this in other threads and banning anyone who does it persistently.

Fixing it seems difficult. It seems like a bug pretty deep in how the bbcode parser works. If anyone knows how to fix it, let me know.
1105  Other / Meta / Re: Nominate (insert name here) to the default trust list on: June 18, 2015, 04:03:49 AM
Everyone assumes everyone else on this forum is a guy. Hell, even my feedback to other people assumes they are other guys. Interesting how we do that... Imagine if I started leaving feedback using 'her' all the time--it just feels weird.

In English, "masculine" pronouns are actually gender-neutral. It is appropriate to use "he" when you don't know the person's gender.
1106  Other / Meta / Re: Why move all threads regarding the fork to Altcoin Discussion? on: June 16, 2015, 05:37:26 AM
All of the moderators have orders from the administrators to move threads solely about Bitcoin XT to the alt currencies section. Threads involving both Bitcoin Core and Bitcoin XT are allowed to stay in Bitcoin discussion.

As I mentioned in that PM, this policy only applies to XT once it is actually modified such that it diverges from the Bitcoin network/currency, which is not yet the case. It's an awfully complicated issue, and this was sort of buried near the bottom of my three-page justification PM, so I don't blame you/anyone for missing it.

Huh? I didn't receive anything like that.

It was only sent to a few mods.
1107  Other / Meta / Re: Why move all threads regarding the fork to Altcoin Discussion? on: June 16, 2015, 02:52:04 AM
Once XT hardforks, it will be an altcoin. I was thinking that it was supposed to hardfork today, so I didn't move the threads back when I saw them moved yesterday. I moved them back for now.

1109  Other / Meta / Re: Is these 'bitcointalk' sites real? Or all of them are scam sites? on: June 15, 2015, 07:10:09 PM
I recommend strongly against logging into those sites. Even if they're not intended to be phishing sites, you'd be giving your forum username and password to a third-party with worse security than, probably over an unencrypted connection.

It's fine if you want to create a mirror, but please:
- Change the page so that your mirror doesn't contain any login forms.
- Delist your mirror from search engines using robots.txt (except maybe the front page and mirror-specific pages). Google is really bad at determining the origin of content.
- Don't fetch pages from more frequently than once per second.

1111  Bitcoin / Development & Technical Discussion / Re: Hash algorithm that cannot be implemented in ASIC ? on: June 15, 2015, 02:09:54 AM
What about another solution which I haven't yet seen mentioned:

Every x blocks, you change algorithm.ASICs.

I wonder if the network could somehow take psuedorandom data from the block chain and then use this to create a random hash algorithm. It's hard to imagine how this would be done without using a fixed set of algorithm patterns, though. Maybe each node could use the pseudorandom data as input into identical evolutionary algorithms that end up producing one acceptable hash algorithm. (Can a computer prove that a random algorithm is secure enough for PoW?)
1112  Economy / Auctions / Advertise on this forum - Round 152 on: June 15, 2015, 01:47:44 AM
The forum sells ad space in the area beneath the first post of every topic page. About 25% of ad income goes to the forum moderators as thanks for all of their work. (There are many moderators, so each moderator gets only a small amount -- moderators should be seen as volunteers, not employees.) The rest is stored in the forum's treasury (verifiably), where it sits until the forum needs it.

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. 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. Eight 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.

The ad lasts at least 7 days starting from when I put it up. (However, if you look at the ad history you'll see that ads usually get at least 8 days, and sometimes as many as 10, but this is random and definitely not guaranteed.)


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.

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.

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 eight slots are filled.

So if someone bids for 8 slots @ 5 BTC and this is the highest bid, then he'll get all 8 slots. If the two highest bids are 8 slots @ 4 BTC and 1 slot @ 5 BTC, then the first person will get 7 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 0.05.
- The bidding starts at 0.50.
- I will end the auction at an arbitrary time no more than 12 days from now. (I will probably end the auction 1-3 days before the ads are scheduled to go up.)
- 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.

1114  Other / Meta / Re: Is there a way to on: June 14, 2015, 07:26:11 AM
No. It's an issue of fairness, not a technical limitation.

I can manually make threads self-moderated (only I can do this), but I only do this if the thread is extremely long/entrenched and the OP is trustworthy, since you are not allowed to delete any posts made before the topic became self-moderated.

No. It wouldn't be fair or right to self-mod a thread after you've created it. Just lock the thread and create a new one if you wish to self mod.

I'm curious. we know that topic can't be converted to self-moderated or vice versa, but what will happen if you merge a new self-moderated thread with an old normal thread?

When merging, you merge from a topic into another topic. You don't add two topics and get a new topic. So it'll be whatever the destination topic is. When splitting, the new topic is not self-moderated. If you move a topic to a section where topics cannot be self-moderated, it loses its self-moderated status for as long as it is in such a section.
1115  Other / Meta / Re: An apology... on: June 11, 2015, 04:40:13 AM
I have indeed received the 50 BTC.

I accept your apology, and I don't have any negative feelings toward you, though your actions here were very unprofessional. Probably it will take quite some time before people can look back and view this just a temporary lapse in judgement that was quickly resolved.

It seems that those two posts you were complaining about were deleted by a moderator (in response to your reports) before he even saw your thread. We wouldn't have changed/violated forum policy as a result of this issue.
1116  Economy / Service Discussion / Re: Certified Bitcoin Professional on: June 09, 2015, 07:06:15 AM
I see theymos is offering a certification now:

I would suggest people seek legitimates certifications rather than buying one from theymos and offer legitimate certifications.

The forum's expert "certification" (recently also extended to /r/Bitcoin) predates "Certified Bitcoin Professional" by at least a year, I think. Here's where I officially announced it, though it existed for quite some time before that. People with a Bitcoin expert badge (or an equivalent core dev badge) are intimately familiar with the theory and inner workings of the Bitcoin network, and they are able to intelligently discuss any proposed change to the network. If they time-traveled to 2007, they would be able to reconstruct something feature-equal and at least a little better than Bitcoin from scratch.

Receiving this badge requires a recommendation from someone who already has the badge and approval by an admin. There is no fee or exam.
1117  Other / Bitcoin Wiki / Re: Proposal: ads on the wiki on: June 09, 2015, 05:34:58 AM
Can you give us an estimate of wiki traffic and costs, how much is saved by opening that gateway?

In the last 7 days there have been 2,240,172 requests from 152,385 unique IPs.

I can't estimate long-term ongoing costs now with any sort of accuracy because the wiki isn't on its final server yet, I'm not sure whether the final server will be sufficient, and I'm not sure how much work bawolff will need to do in the long-term (right now he's doing a lot of work to get the wiki in good shape).

The ads will need to be manually approved, and maybe new or dangerous-looking services should be disallowed.
1118  Bitcoin / Development & Technical Discussion / Re: Hash algorithm that cannot be implemented in ASIC ? on: June 08, 2015, 08:45:53 PM
Anything can be implemented in an ASIC, though maybe you could design a hash algorithm that gives modern computers enough of an advantage to discourage ASIC creation. (But I don't know that much about hardware.)

I see two problems with memory-hard PoW:
- If it takes a few seconds to complete one hash, then the network can be DoS-attacked by broadcasting many invalid blocks which nodes then need to waste tons of time checking. It'd be nice to have an asymmetric PoW algorithm that requires much more time to create a PoW than to verify one.
- AFAIK it's not actually that expensive to create ASICs with a lot of memory, and it looks like scrypt ASICs have in fact been created.

I wonder if ASIC design/creation would be made prohibitively expensive if the hash algorithm was especially complex. For example, if the simplest way of representing the algorithm in assembly code was 1 GB in size, I suppose this would be quite difficult to translate to an ASIC, but not any particular obstacle for general-purpose CPUs. You could still create an ASIC that worked like a CPU but with only the subset of CPU features actually used by the hash algorithm, but this'd be pretty expensive to design and might not earn you much extra efficiency.

I also wonder whether it might be good to use a PoW that is especially easy to build an ASIC for, but so simple that the most dead-simple ASIC design is always the best one. Then you'd have to buy hardware to mine, but no ASIC would have much advantage over any other. I don't know if this'd actually help anything since there'd still be economies of scale in power consumption, though.
1119  Other / Meta / Re: Anonymous Moderation is cowardly. on: June 08, 2015, 05:00:48 AM
The only reason you would need to know who deleted something is to pester them about it, which would be a pointless annoyance that might even prevent moderators from doing a good job. Admins are the only ones who can restore deleted posts and the only ones who can properly deal with inaccurate mod actions: post in Meta and we'll look into it.

Self-moderation is moderation in addition to global moderation. Both of those posts were insubstantial, so deleting them seems correct.

I guess whenever your post gets deleted because of the comment to which you responded to also got deleted, you personally get a message from the moderators explaining that "the post got deleted because it was a reply to other deleted post", at least this is what I got from grue when my post got deleted in these situations. So I don't think this is the case.

That sort of message isn't always sent.

I wouldn't call it anonymous either. Most people who frequent the ALTCOIN sections knows that mprep is the moderator.

Even sections with assigned mods can also be moderated by global mods.
1120  Other / Meta / Re: Default Trust Visualisation [Picture Heavy] [3rd June] on: June 03, 2015, 03:37:28 AM
Those images are pretty cool-looking. Does anyone see anything in them that would suggest specific changes to the default trust list? I was trying to look for "islands" of not-default-trusted people that aren't just created by one person, but nothing stood out. I wonder if it'd be good to increase the default depth to 3 -- a lot of the graph isn't trusted by default.
