On a note, there seems to be a LTC selloff going on on BTC-E...

I can't conceive someones motive in engaging in that but the hashrate already seems affected and the next difficulty adjustment seems to be down! Shocked

What gives? I thought the whole idea of the cpu intesivity was to allow BTC miners the ability to mine simultaneously. Why aren't we seeing that in the hashrate. Now we see a difficulty drop. Time to panic and sell?

There are other CPU cryptocurrencies, they could be mining those for now. The only reason this doesn't happen with Bitcoin is because it's got so much inertia already. Eventually merged mining will solve this, so I wouldn't panic... But don't trust anyone's speculation on this forum. Roll Eyes

There are almost 1,000,000 LTC now.
What do you think - how many LTC will there be by the end of the year ?

Is this an opinionated question of some kind? The generation over time is more or less completely predictable.

But still it depends on how many people use LTC now and how many will be in next months.

50 LTCs are generated about every 2.5 minutes. That's 1200 LTCs an hour and 28,800 LTCs a day. You can probably calculate for yourself how much litecoins there will be total by the end of the year.

And like others have said, the difficulty adjusts about every 3.5 days to keep the generation at this target. So it's an estimate, but it should be fairly close.

To a small degree but any difficulty based blockchain (including LTC) simply adjusts the difficulty to increasing or decreasing hashrate to keep the rate of coin generation relatively constant.

The new build works very nicely on Windows.

Since the solo mining uses the internal miner in the Litecoin-qt application itself, the user won't benefit from having a CPU-instruction optimized minerd. (In my case, I get about 3 kh/s when solo mining vs. 3.75 kh/s when pool mining) Of course, the user could just use pool mining with 127.0.0.1 as the server address.

Otherwise, you've made the miner GUI far better.

Yup, solo mining is for the novice users that don't want to muck with minerd. It's about 80% as efficient, but it works well and is simple. If you have an optimized minerd, you can point it to a pool or to yourself using 127.0.0.1. Most people will probably use a pool anyways.

How much electricity do CPUs use compared to GPUs? For instance, would a high-end GPU mining BTC use more electricity than a high-end CPU mining LTC per unit time? Would the difference be significant?

Might've been asked already, but it's a huge thread to sift through, and there doesn't seem to be a wiki anywhere.

The wiki seems to be down, but here is a google cache of most gpus/cpus and their wattage, hashes, etc. Note that references to hashing is BTC only, but you should still be able to get an idea of watt usage.

- Remember last state. So client will start up and automatically and mine (solo or pool) if it was previously closed in that state

Where is this stored?

It's stored in the same db as other config params in Bitcoin. It looks like it's using the wallet db, which seems silly but I didn't bother changing it.

I tried those things when developing the GUI and opted for enabling the protocol dump option.

Ok, I put the protocol dump back and ignored those outputs:
https://github.com/coblee/litecoin/commit/57a3a98d808b1e500cf11cc312f9cf5746145fd2

Let me know if that works on Windows. It should.

You seem to have taken the protocol-dump parameter off. I had it enabled because otherwise it would take very long time for the output buffer to get filled and cleared (so the GUI application could read the output). It took around 3 minutes before it even showed the hash rate /wo protocol-dump being enabled.

Seems to be behaviour that differs between OSes. (I use Windows)

It causes a new problem with the new Debug Logging option though... Maybe if the protocol-dump related data could be omitted somehow?'

Didn't you add this read timer to read output every 500 millisecond?
https://github.com/coblee/litecoin/blob/master/src/qt/miningpage.cpp#L29

That seems to work for me. Is it not working on Windows?

Not working on Windows. It only reads the output once the output buffer has been filled.

Can you try a few things on Windows? Instead of waiting on signal readyReadStandardOutput(), use readyReadStandardError(). Does that help? If not, how about just readyRead()
I know minerd only outputs to stderr, so stdout might not be flushed after each printout.

Still need to do:
- save config values using db as oppose to easyconfig.txt
- hook up solo mining option
- hook up mining status and hashrate with status icon at the bottom
- maybe move mining tab to right most tab (let me know if you don't want that)

Done!
- Remember config settings in db
- Implemented solo mining option to hook up with internal miner
- Hooked up mining hashrate status with status icon for both solo and pool mining
- Remember last state. So client will start up and automatically and mine (solo or pool) if it was previously closed in that state
- Moved mining tab to last tab on right

It will only take one person to complain about it and I am certain that the FireFox block and google will block the site without a second thought.

I am not sure where you got such a negative view of the technology lol. On top of a decent ad replacement imo. I have seen someone have that either set up the page or was going to, that has it donate to NORML. So another use would be charity. Another idea is if Wikipedia were to implement it, it could run properly without worrying about donations. I think there is a lot of positives that could come, instead of focusing on the one negative of a botnet abusing it, as a botnet can abuse a lot of good things, doesn't mean they shouldn't exist imo
