Just noticed this  

Someone tell them to re-direct HTTP to HTTPS version.

I think you just did. And what status code should they use for the redirect for maximum SEO friendliness - 301 permanent ? Then make sure that all promoted home page links contain a consistent protocol: http or https ?

Why use https for just regular stuff ? It's slower.

Thanks, I was missing a couple lines in the htaccess. Fixed now.

RewriteEngine On
RewriteCond %{HTTPS} off
# First rewrite to HTTPS:
# Don't put www. here. If it is already there it will be included, if not
# the subsequent rule will catch it.
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
# Now, rewrite any request to the wrong domain to use www.
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^(.*)$ https://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

HTTPS also prevents a naughty ISP from injecting ads ala comcast

Thats it, am all done with the on topic stuff for friday night

This is why I like the randomness of this thread.  I always learn something new!

Time for off topic? Ok! You may want to have a look at the namecheap Black Friday and register some dash domains for pennies  Up to 98% OFF. You can even pay with Dash (shapeshift.io ->Bitcoin)

Have you done the HTTP vs HTTPS Test lately?

Wow. Never knew about that.

I just assumed it was slower because of the time taken to encrypt everything and also to communicate with the certificate authorities etc.

Communicate with CAs? You don't communicate with any certificate authority when using HTTPS...

Thinking of the crl check?

Right, but those are stored by you, and you check to ensure the site has a cert signed by one of them, because you trust those CAs. You're not communicating with the CA itself - that would be a lot of overhead.

Ah yes, I mentally confused this with a server issue we dealt with due to CRL servers being blocked off.

Thats looking very healthy : https://chainz.cryptoid.info/dash/#!extraction

Well, duh, of course it was CPU-only at the start. I'm asking if the intent was to make it easier on GPUs than Quark.

I think he just did it his own way, as he didn't know about Quark, which is the impression I got long ago when I asked - don't ask me to find proof, I'll not waste my time.  Just giving you an answer if you're interested.

I suppose it's possible. Meh, hardly matters, I suppose. I just want to know his intentions for the PoW - what qualities he wanted it to have.

I think Evan should chime in..that is the best answer

the author said:

It was probably inspired by the chained-hashing approach of Quark, adding further “depth” and complexity by increasing the number of hashes, yet it differs from Quark in that the rounds of hashes are determined a priori instead of having some hashes being randomly picked.

The X11 algorithm uses multiple rounds of 11 different hashes (blake, bmw, groestl, jh, keccak, skein, luffa, cubehash, shavite, simd, echo), thus making it one of the safest and more sophisticated cryptographic hashes in use by modern cryptocurrencies.

The name X11 is not related to the open source GUI server that provides a graphical interface to unix/linux users.


Balanced CPU/GPU mining

When Darkcoin was initially launched with X11, it was only mineable through CPU mining programs. After a spike in the Darkcoin network hashrate in early February 2014, it was speculated that someone might have made a GPU miner and thus a bounty of over 3000 DRKs was given in order to assist in the creation of a GPU miner client that could be publicly available, for fairness reasons.

By mid-February the GPU client was launched and by late-February it was optimized for higher hashrates. At the same time, the CPU mining clients evolved to increase their speed by using the SSE2/3/4, AVX and AES instruction sets.

At that point it became evident that the hashrate difference between GPU and CPU implementations were not that chaotic, although GPUs still took the crown in terms of energy efficiency. Top of the line and tuned CPUs, like a 6-core i7s running at 4.5 GHz produced 880 khashes/second when GPUs like AMD's 280 and 290 gave 3 times as much.

A ratio of 1:3 was thus established for the fastest CPUs versus the fastest AMD GPUs – which is significantly better than Scrypt or SHA256 and allowing CPU users to mine X11 coins. By June 2014, the ratio had gone up to 1:6 due to the evolution of GPU mining programs and relative stability of CPU mining programs.

It should be noted that these ratios are more a reflection of the mining programs rather than an inherent property of the algorithm itself and thus the ratios can change depending the development progress of the CPU and GPU mining clients.

is that you wolf0 that got 3000 DRK?

i highly doubt Evan didn't know about Quark, Quark was months ahead of dash launch

(blake, bmw, groestl, jh, keccak, skein) Quark

(blake, bmw, groestl, jh, keccak, skein, luffa, cubehash, shavite, simd, echo) X11

Haha, no. I would be ashamed to have written that miner.

kindly describe the miner? in layman's terms..is it crippled? purposely unoptimized? is it written by savages?

you devs kind of have a "third eye" in this crypto sphere. enlighten us.

It was done for a bounty, and it works. I'm not going to demonize the guy - X11 is a lot of logic to optimize, and using copypasted CPU libraries was pretty much the fastest way to get a GPU miner put together for the 3000 DRK. But it was dead slow. This was the darkcoin kernel, not Girino's darkcoin-mod kernel.

I wouldn't say it's purposely crippled, just a little above minimal effort put into it.

for me a copypasted libraries is kind of crippling to my eye if the miner stayed for a while before any decent GPU miner was created...thanks for another insight.

IMO, the real decider is intent. I'm pretty sure it wasn't done to slow it on purpose, it was to be the first done with a GPU miner and get the bounty. That kind of reward rarely incentivizes excellent work.

Girino's code was stolen from binaries he made with a fee embedded - which is what we call darkcoin-mod to this day. I saw that code and it was still terrible, so I improved it. Thankfully, my sources haven't leaked, but the binaries have.

The idea behind the launch of XCode and X11 was to have a brand new algorithm. My code was based off of Litcoin, Quark (a few of the hashes) and Primecoin (difficulty algorithm). I went and looked up all of the SHA3 candidates and took the rest, then I removed a lot of the logical switches from the hashing algo that quark used.

I wanted to create a new algorithm, so that we went through the same stages as Bitcoin and Litecoin did. First CPU, GPU, FPGA, then ASIC. That's the general path that these currencies go down and I thought, since the two most successful followed that, my currency should as well. As for the GPU miner, it was contracted for a few hundred dollars worth of Dash and we got a miner that was pretty much unoptimized. But that was really good for the time and allowed a good portion of time for the network to update to GPUs without making CPU mining unprofitable instantaneously.

That's pretty much exactly what happened.

this should be edited again..Evan made a statement

I wouldn't say "a few hashes" about quark though 6 is still greater than 5.

and what would be the effect of this fork on GPU mining? is it limiting?policing?

What do you mean by "a few hashves about quark"?

And what fork are you talking about?

thank you

friendly reminder to stop directly quoting known trolls as arielbit (see his post history)

I do know he was posting troll-like comments, but as long as he can have a civil discussion, I see no issue with it.

The issue is that most of us have arielbit on ignore and you directly quoting his lenghty posts is interfering with that ...  why not just blank out his comments like most of us do with trolls
when feeling like responding to troll posts ? (this goes for everyone by the way)

How do you know how many people have him on ignore? Do you always speak for everyone? Or only when you're trying to censor and belittle people you don't agree with. Wannabe mod and control freak over here

I think I've got here earlier than you  



besides I'm reminiscing the fate of GPU's on X11 mining with dash.. and having a converse with a miner developer gives great insight.

[hugs1BTC]

I think DASH is one of the game-changing altcoins that will stay on top together with BTC in the future.
People thought that LTC was at the second place, but I see no future for it. At least, it's a widespread altcoin, but DASH has all the key features to replace LTC.
I converted all my LTC into DASH in the last pump, and I'm so happy about my choice Also I still mine DASH with my small rig.

[DrkLvr_]

Can you confirm the price you sold LTC and the price you bought DASH?
