Quote from: tcatm on August 16, 2010, 00:43:39 I propose to compile sha256.cpp with -O3 -march=amdfamk10 (will work on 32bit and 64bit) as only CPUs supporting this instruction set (AMD Phenom, Intel i5 and newer) benefit from -4way and it’ll improve performance by ~9%. GCC 4.3.3 doesn’t support -march=amdfamk10.  I […]

Yes. Any built proxy implementation would be open source and automated bitcoin payments would be great. I will post the psiphon info. and links because the project has just moved from v1 to v2 and the implementations are very different. Psiphon is a free ‘circumvention’ tool and should remain so. […]

Mihalism Multi Host is a popular open source PHP file hosting server. It’s geared toward image hosting, but I think by increasing the file size limit and liberalising the allowed file extensions, it could just as easily be used for general file upload hosting.  They need the limits to keep […]

Add this to the ‘cons list’ for cash: – Possibility of RFID imbedded into the bills. They could be read by the machines at your local post office and throw a red flag on the destination address. LR and Pecunix have many established exchanges to paper currencies by various payment […]

Is http://www.bitcoin.com a valid implementation of the bitcoin protocol? How are they able to use the name? Does anyone know who is behind it? It’s unrelated.  There wasn’t anything there when I started. The price of .com registrations is lower than it should be, therefore any good name you might […]

Good idea. I’ll eventually be setting up a ‘one hop’, SSL, http, login protected proxy service (similar to the 1st Psiphon project) and accepting bitcoins as payment. I’m UK based so it will be good for using BBC iplayer etc. 🙂 I will be giving bitcoin users priority service, as well […]

A week or so ago I met a very nice Freenoder staffer in the #bitcoin and #bitcoin-dev channels. He told me that the #bitcoin channel turned up on Freenode’s radar as it looks like a Botnet Command and Control channel, but after I explained to him how Bitcoin works and […]

When you want to upload an image to embed in a forum post, there are services like imageshack, but because they’re free, they limit the number of views.  It’s a minuscule amount of bandwidth cost, but they can’t just give it away for free, there has to be something in […]

Hi, I run bitcoin at a nice level of 20 so as not to interfere with other tasks. Every now and then, however, it seems to auto-adjust itself to nice level 2, or even 0. It this by design? Frankly, such a thing should be illegal for a linux application… […]

Quote from: sirius-m on February 24, 2010, 18:17:35 This is strange… When I start Bitcoin as a daemon on my 64 bit Linux server, it eats up all the 250MB of remaining RAM, 700MB of swap and eventually crashes. On my 32 bit Ubuntu desktop, it works fine and stays […]
