2901  Bitcoin / Important Announcements / Bitcoin Core (Bitcoin-Qt) 0.9.1 released - update required on: April 08, 2014, 10:45:42 PM
If you are using the graphical version of 0.9.0 on any platform, you must update immediately. Download here. If you can't update immediately, shut down Bitcoin until you can. If you ever used the payment protocol (you clicked a bitcoin: link and saw a green box in Bitcoin Core's send dialog), then you should consider your wallet to be compromised. Carefully generate an entirely new wallet (not just a new address) and send all of your bitcoins there. Do not delete your old wallet.
- If you are using any other version of Bitcoin-Qt/Bitcoin Core, including bitcoind 0.9.0, you are vulnerable only if the rpcssl command-line option is set. If it is not, then no immediate action is required. If it is, and if an attacker could have possibly communicated with the RPC port, then you should consider your wallet to be compromised.

This vulnerability is caused by a critical bug in the OpenSSL library used by Bitcoin Core. Successfully attacking Bitcoin Core by means of this bug seems to be difficult in most cases, and it seems at this point that even successful attacks may be limited, but I recommend taking the above actions just in case.

If you are using a binary version of Bitcoin Core obtained from bitcoin.org or SourceForge, then updating your system's version of OpenSSL will not help. OpenSSL is packaged with the binary on all platforms.

Download 0.9.1
Announcement

Other software (including other wallet software) may also be affected by this bug. OpenSSL is extremely common.

484 accounts were updated. If your wiki account's email address as of March 31 had the same email address as your forum account as of April 2, and if you met the activity requirements on April 2, then your wiki account should now be capable of editing.
2904  Other / Meta / Re: Those who are Spamming the trust system. Action needs to be taken! on: April 05, 2014, 03:08:38 PM
Trust spam isn't allowed. If I see anyone posting dozens of fake trust ratings (from one account or many alt accounts), I will delete all of their ratings. But Inaba is hiring multiple people to create these ratings. It is impossible for me to determine whether these ratings are "real" or not, so I'm not going to delete them. (Obviously all negative ratings are very likely to be fake, but I'm not going to guess about this.)

I agree that it is a little annoying to see a wall of negative ratings, but this is in the "untrusted" section. The way things are set up currently, untrusted ratings can be easily spammed in a number of ways. That's why those ratings are hidden by default.
2905  Other / Meta / Re: Is my IP address blocked? on: April 05, 2014, 03:24:50 AM
It's possible. We've recently been seeing many IPs that drain tons of bandwidth or perform requests very quickly, so we've started banning some of these. You shouldn't have been banned unless you were doing something very unusual, though.

PM me your IP.
2906  Other / Bitcoin Wiki / Re: Want to edit the wiki without paying a fee? Read this. on: April 04, 2014, 08:05:11 PM
It's not done yet. However, the data collection part is probably done now, so trying to get more activity or creating a wiki account probably won't get you anything now. I will announce the details here when it's all done.
2907  Other / Meta / Mining hardware reorganization on: April 03, 2014, 07:19:33 PM
"Custom hardware" is now called Hardware. The old Hardware section is now "CPU/GPU Bitcoin mining hardware" and archived. You can't post new topics or posts to an archived section, but you can move your topics out to a different section. If a topic should be moved out and the topic-starter is not available to do it, report the topic.

All Bitcoin hardware talk should go in the (new) Hardware section. Altcoin hardware talk should go in the altcoin mining section.
2908  Economy / Auctions / Advertise on this forum - Round 117 on: April 03, 2014, 06:15:46 PM
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 (no marquee or blinking). Ads must appear 3 or fewer lines tall in my browser (Firefox, 700px 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.)

Stats

Exact historical impression counts per slot:
https://bitcointalk.org/adrotate.php?adstats

Info about the current ad slots:
https://bitcointalk.org/adrotate.php?adinfo

Ad blocking

Hero 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 counts 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 bitcointalk.org 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.

Auction rules

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

I reserve the right to reject bids, even days after the bid is made. In particular, bids from people with less than 15 activity points are likely to be rejected. I recommend not getting into a bidding war with someone who has less than 15 activity points, as their bids might not be accepted, but your latest bids will still stand. If you need to know right away whether someone's bids will be accepted, PM me.

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.

You must pay for your slots within 24 hours of receiving the payment address. Otherwise your slots may be sold to someone else.

2910  Other / Meta / Re: DARK THEME for bitcointalk? on: April 03, 2014, 02:22:55 AM
I previously said that I'd re-enable SMF themes, but now I'm thinking that this would be an awful pain. SMF themes work by duplicating a ton of code, which is difficult to maintain.

Has anyone tried writing a custom stylesheet for the forum? Is it possible to implement a dark theme that way? (How can I help?) If someone writes a good one, I'll figure out a way to let other people use it without installing any software.
2911  Other / Meta / Re: Image proxy broke :( on: April 01, 2014, 10:40:12 PM
Invalid image through multiple refreshes of https://bitcointalk.org/index.php?topic=92621.0

The source image is broken.

"Invalid image" errors usually really are a problem with the image, not the proxy.
2912  Other / New forum software / Re: Questions by gweedo; split from: Kick-off Discussion on: April 01, 2014, 05:21:37 AM
Maybe it can be tried out later once the main features are done. The server currently sends an average of about 20 mails per minute, which is not so bad. Though troubles might start occurring if this ever increased to a few mails per second (over a long period of time), as public-key crypto is extremely slow. No amount of software trickery is going to help if the hardware just can't keep up.

If standard public-key crypto isn't possible, the forum and the user could establish a long-term shared secret and then use symmetric crypto, which is very fast.

But IMO this is a pretty low priority. Emails usually don't contain sensitive info.
2913  Other / Meta / Re: BFL bringing down the trust rating? on: March 31, 2014, 02:59:52 AM
He asked me whether he could demonstrate that the Trust system is broken. I said that he could, though I didn't know exactly what he was planning, and I don't like what he's doing here. Trust isn't the right way to respond to people whose posts you dislike. If I'd have known that he was going to do this, I would have warned him that it would probably result in significant backlash...

I'm happy with the performance of the Trust system here so far. I have a few more default-untrusted negative ratings, but Inaba's default trust score went from ~5 to -261 overnight. (I did not change anything about how the Trust system works for this.)
2914  Other / Bitcoin Wiki / Re: Want to edit the wiki without paying a fee? Read this. on: March 28, 2014, 11:12:36 PM
Rather than a one time thing, could that be made permanent?

Probably not, but I do want to figure out good ways of allowing more people to gain editing privileges without paying a fee.
2915  Other / Bitcoin Wiki / Want to edit the wiki without paying a fee? Read this. on: March 27, 2014, 11:17:28 PM
In a few days, everyone whose wiki account has an email address matching a forum account will automatically gain free editing privileges if their forum account has at least 45 activity.

So if you meet this requirement or will very soon, make sure that you have a wiki account with an email address exactly equal to your forum email address. If your activity level is 28 or lower, then it will be impossible for you to get the required activity score in time.
2916  Other / Meta / Re: Bitcointa.lk what is it??? on: March 26, 2014, 11:17:45 PM
Those IPs are not blocked currently. But your other abusive IPs were blocked. Just your quotefast requests (which are only part of what your crawler does) were occurring at an average frequency of 7.6 requests per second in the most recent access logging period. Your requests constituted 3.4% of all forum requests in this period. This is entirely unacceptable and of course resulted in those IPs being banned.

The maximum allowed bot request frequency is 1 request per second. Those IPs are now accessing pages at an average of 2.5 requests per second combined. If you continue exceeding the allowed request limit, we will continue banning your IPs.
2917  Other / Meta / Re: Bitcointa.lk what is it??? on: March 26, 2014, 10:31:58 PM
What IP?

IPs are only banned for over-use if they request pages more frequently than once per second. Faster requests are not allowed.
2918  Other / Meta / Re: Images not loading well on: March 26, 2014, 10:19:38 PM
I think that I figured it out. Chrome was creating so many connections that the server was temporarily thinking of you as an attacker and dropping your packets. Other browsers also do this sometimes, though not as much. I increased the limits for this. But really, browsers should not be creating 30+ connections to the same server...
2919  Other / Meta / Re: Image proxy broke :( on: March 26, 2014, 04:06:33 AM
Fixed it. Also, it will maybe be faster now.
2920  Other / Meta / Re: Images not loading well on: March 25, 2014, 05:42:48 PM
I did slightly change the way that the proxy works recently, but I don't know how the change could cause this problem.
