Difficulty is increasing... +15%!

I have just noticed a curious fact: at difficulty 1, the expected daily earnings in coins/day equal the hash rate in khash/s, with an error of less than 0.6%!

Suppose your hashing speed is 1 kH/s: you will compute 86,400,000 hashes a day. At difficulty 1 the probability of finding a block is 2-32 per hash. Since a block is worth 50 coins, your expected daily earnings will amount to
86,400,000 / 4,294,967,296 * 50 = 1.00582838058

This means that you can estimate your daily income by simply dividing the hash rate by the difficulty. Now isn't that remarkable?

Currently the API is like this (in php print_r() format):

Code:
Array
(
[user] => Array
(
[total_rewards] => 0.0
[paid_rewards] => 0.0
[unpaid_rewards] => 0.0
[past_24h_rewards] => 0.0
)

[workers] => Array
(
[user.worker] => Array
(
[hash_rate] => 0.0
[valid_shares] => 0
[stale_shares] => 0
)

)

[pool] => Array
(
[hash_rate] => 697
[pps_rate] => 0.00096512
)

[network] => Array
(
[hash_rate] => 22763
[difficulty] => 0.76679615
)

)

All the workers' names include a dot, and it's 500 if I use the data like this:
Code:
echo \$lp["workers"]["user.worker"]["hash_rate"];
How to use it correctly?

The dots should not be an issue if you use associative arrays. The following code works for me:

Code:
\$api = json_decode(file_get_contents("http://www.litecoinpool.org/api?api_key=my-api-key-here"), TRUE);
echo \$api["workers"]["pooler.1"]["hash_rate"];

Just signed up!  Looking forward to making my server room even hotter now that the CPUs are in use lol

Welcome aboard, Red Emerald!

By the way, for those of you who are doing both CPU and GPU mining with an ATI card on the same rig, consider updating ATI drivers to version 11.12. This new version should solve the CPU usage problem, even on multiple-card setups. I have just carried out the update on my main box, and I now have one more core for mining Litecoin. Plus, temperatures dropped considerably!

(Thanks to grue for the heads up!)

Yup, I noticed that too, only problem is I still can't use all my cores to mine LTC because then the GPU miner almost stops. And also when I don't leave 2 idle cores the GPU miner mines a bit slower.

Uhm, bizarre. On my main Bitcoin rig I see no slowdown at all using both CPU cores of a Sempron for Litecoin (5.8 kH/s) and two 5870's for Bitcoin (850 MH/s). This is using ATI drivers 11.12 and AMD Stream SDK 2.5, under Linux. And CPU temperature went down from 64°C to 60°C. Works like a charm now!

Bitcoin... and Litecoin... live together in perfect harmony...

+/- fixed by setting GPU miner affinity to a single core and raising its priority while lowering LTC miner priority.
Still, I don't get how your CPU temperature can decrease if all you did in the end was replace a 100% CPU usage by driver mess with a 100% CPU usage by LTC miner...

Yeah, I know it might sound confusing. The point is that total CPU usage is the same as before, but CPU load is not.

Lucky you... I have the same temps as before, around 58-59°C (Phenom 2 955 @3.6GHz)

Windows or Linux? If you're using Windows, it might well be that excessive load (not cpu usage) was only a problem under Linux, and you didn't experience it even with the old drivers.

Windows. Don't really know how to tell the difference between CPU usage and load from the task manager indeed, unlike on Linux where top makes it obvious ^^

You might have noticed I have moved the payout history to a separate page, adding links to the block explorer for each transaction. I have also added the possibility to change the donation percentage because, believe it or not, one of our miners wanted to donate more.

By the way, is anybody interested in an iPhone interface to check your live stats? Let me know!

i'm interested in a iPhone interface. I love checking my miner stats throughout the day

Alright, link to the mobile interface now available on the "My Account page". You can add an icon for it to your Home screen via Safari.

Automatic payments used to be carried out every hour, but I changed that to twice daily when I added the instant payout option, in order to minimize the number of transactions.
When I applied the changes I corrected the description in the feature lists (both on the site and on here) and on the "Payments" page, but I forgot to correct the textual description on the home page. Sorry for that, it's fixed now.
