RK can you repoint DNS for explorer.skeincoin.org?

RK IS ALIIIIIVEEEE!!!! 

Wallet updated.

Ouch. It's rather common that FPGAs are slower than GPUs but more power efficient, but this is a bit too far from practical.

GPUs run at about 1 GHz, which is way less than current CPUs. They just have so many cores/threads running in parallel. They also have more/faster memory than common FPGA boards. (Though I wonder if the SRAM of DE2-115 could be put to good use...)

When I hacked together my first FPGA code, I didn't really know/care about timing (and I'm not much wiser today ). The suggested speed limit was about 70 MHz, but the Spartan 3E didn't have the flexibility of the Cyclone IV clocking, so I just built 50 and 100 MHz versions, and they were both fine. Sure, you'll get the occasional error, but the overall efficiency is better with a little overclocking. Ztex boards/miners make great use of this idea by dynamic clocking based on error rate.

Offtopic: Keccak is supposed to be really hardware-friendly, so it could be fine even without full unrolling. Opencores has an implementation, but their login systems is having some issues...

HW Testing shows that I can get about 2.5MH/s (for the sha256/skein algo) out of a Cyclone IV E115.  Not impressive.  That's only burning about 1W though, so that's 2.5MH/s/W which is kinda "cool" if you're gonna make a large rig of dozens of FPGAs.  With my rig, once I get the stratum proxy working, I'm expecting around 180MH/s for myr-skein.  That's about what you'd expect from a single modern GPU ... meh.

Disappointment.

This still will yield about 5x what my rig is yielding today running the scrypt algo though.  ASICs are starting to kick my ass in the Scrypt realm.  Todays cryptocurrency landscape doesn't appear to have much room left for FPGAs.  The algo's are a whole generation newer (and more complex) than they were in BitCoin days and those damned GPUs are REALLY REALLY fast now!  Even though GPUs are not running algo steps in parallel (like an FPGA can) they're running their core at some insane GHz speed that more than makes up for it.  If I really work at timing issues I can get logic steps in the FPGA to run up to 100MHz.  That's roughly the theoretical max for how fast a single fully unrolled instance of an algo machine can run in this FPGA.  The SHA3 generation of algos though are so much more complex than SHA2 that you'd never fit an entire fully unrolled instance in a single IC.  You have to start making trade offs to shrink the logic into something that will fit and this means increasing the number of clocks per hash.  I've run out of steam at 64 clocks per hash for Skein.

Quite a learning experience

Just a quick heads up on the explorer, it will be on the temporary address until probably Thursday (new server won't be provisioned until then!)

For now its on:

http://87.242.230.99/

** UPDATE **

Won't be until Monday now

"Win.Adware.Agent-6810" roflol.... maybe that's because the software i added for android ads (that i never used)... going to remove it now

 You can use the api to do anything... "SOON"™ :-)

ahh maybe thats why it worked now :-)

it works the second time. Had that on first run also.

I can confirm the same findings file is clean. although the game sits on the main screen "Authenticating". EDIT: Lowered res and switched to windowed and worked ok.

The windows version got a false positive on google drive. I mirrored it on my dropbox.

That's it! *pushes against the desk, flips the chair* i'm outta here *leaves furiously the room*....



Btw ByronP, is there going to be an auto trading option sometime on AT? i would like to provide an option for the developers to receive payout in BTC/LTC, sometime in the near future) integrating some of the coins you support that almost no-one else supports (Blake eco and SKC) and also i would really like to use AT.

There is no RL only AFK.  

edit:
I donated some btc for the blockexplorerserver to sheep.
@: 1DwCUcdbqPHHgegRowjGotb7GQsc3iZ2wj
also will be running a fallback blockexplorer on my homeconnection.

Hi,

I am in the process of moving it to another server, IP will change too so I'll msg you new details if thats ok?

Might down for a day though as I'm super busy in RL  

Seems there was a hiccup on the block events watcher... restarted the service with a fix now...

Nice!
feedback:
Stop the shooting sound on pause and make a you-suck difficulty for me, fracking paratroopers killed me.

Looking into it.

Anybody here able to run a block explorer for Skeincoin?

It would be greatly appreciated as our current block explorers are down.
