Hi all, developer of MacMiner here and planning to update to add GPU mining for a bunch more alt currencies. I've compiled the nicehash sgminer from here https://github.com/nicehash/sgminer for macOS 10.11+ and it's available for download here: http://macminer.fabulouspanda.com/commandline/sgminer/

But I'd really appreciate help checking all the algorithms work. -k X11, -k blake and -k Lyra2REv2 are all I've tested so far. Please post any results you get to help me add function in the next MacMiner upate!

Hopefully supports the all following algorithms: Credits, Scrypt, NScrypt, Pascal, X11, X13, X14, X15, Keccak, Quarkcoin, Twecoin, Fugue256, NIST, Fresh, Whirlcoin, Neoscrypt, WhirlpoolX, Lyra2RE, Lyra2REV2, Pluck, Yescrypt, Yescrypt-multi, Blakecoin, Blake, Sia, Decred, Vanilla, Lbry and Sibcoin

[Edit: The bitcoinxt github has existed since 2014, but it's only now over the max block size debate that Gavin Andresen has leant support to it]

As a result of the lack of clarity regarding the current debate about Bitcoin's future, I've tried to put it in simple terms for those who're trying to figure out what's going on.
The below is also available on my blog: http://fabulouspanda.co.uk/blog/index.php?post/2015/05/31/The-Bitcoin-Core-vs-XT-debate-and-necessary-clarifications.

The news that Bitcoin may fork has caused widespread panic among the community. Here I hope to explain a few important facts regarding it's wider implications.

The most well known developers of Bitcoin have raised important issues regarding the long term viability of the Bitcoin network, and the various solutions proposed going forwards. Due to the lack of consensus, this has resulted in a great deal of fear and uncertainty in the user base.

The code which powers the Bitcoin network can be found here: https://github.com/bitcoin/bitcoin This code has evolved as long as Bitcoin has been around. But the debate over the block size limit and how to manage it has caused some of the best known developers to set up another client for bitcoin, here:

https://github.com/bitcoinxt/bitcoinxt
Edit: The bitcoinxt github has existed since 2014, but it's only now over the max block size debate that Gavin Andresen has leant support to it

The former is now referred to as "Bitcoin Core", and the latter "Bitcoin XT". For the time being, you can use the same wallet with both bitcoin clients, and they run on the same network. From the XT github README:

"Bitcoin XT is more experimental than Bitcoin Core, and has a strong emphasis on supporting the needs of app developers and merchants. By running it you not only provide additional services to the network but help build confidence in the implementations, contributing towards consensus for inclusion in a future version of Bitcoin Core.

XT uses the same data directories as Core so you can easily switch back and forth."

If/when the two change dramatically enough, that may no longer be true, in which case the network will 'fork', resulting in a new Bitcoin XT network incompatible with the Bitcoin Core network, which would require different wallets. But the important thing to bear in mind is that if you have a backup of your current wallet now, you can run both clients/networks - essentially, if you have 1 Bitcoin, after the fork (if you have today's wallet backed up) you will have 1 Bitcoin, and 1 'BitcoinXT', each with independent values based on their popular adoption. As Bitcoin is currently by far the dominant cryptocurrency, it is extremely unlikely that both possible future versions of Bitcoin would either cease to exist or lose all value, and the developers are doing their best to avoid a fork and reach a common solution to the necessary evolution of the technology.

So please, try to keep the debate about this big news relevant to the facts and keep in mind that as with all Bitcoin news, many people will attempt to use the news to manipulate those without full knowledge of it to affect the price in their favour. We need discussion, not panic.

Hi everyone,

You might know me from MacMiner, but that's not what I'm talking about here.

Recently I've been working with a multimedia production company and they've expressed a desire to give bitcoin a shot, with a couple of options.

First off there's the executive credit for a short film (15mins) which will be released on the festival circuit and the cast and team will be attending to promote in Cannes. The film is art and fashion oriented and written/directed by a cutting edge clothing brand with good exposure and a future feature is currently being fleshed out - I can't post more details publicly but I can put the right people in touch with the producer.

The investment for the executive producer credit would be 20BTC at the time of writing and I figured some of those ahead of the game in Bitcoin might consider that a very good deal for the imdb entry.


Their other project is a series of music releases in conjunction with digital media and I was hoping that perhaps someone here can point me in the direction of Bitcoin's interaction with music/film industry to date, and advise on the best method of accepting payment and distributing files.


Are you bullish on my prospects? 

I've been taking BTC/LTC/VTC donations for a while now, but sometimes people say they want to donate but only if they can do it in fiat (usually dollars). Is there any easy way for me to set it up so people donate fiat, but I receive BTC?

Hi everyone,

I've decided to set up a new charity to raise Bitcoin for various BTC accepting currencies. I've set up a livestream.com account at http://www.livestream.com/giveabit and will be streaming our events there for free. A fuller explanation can be found at http://fabulouspanda.co.uk/giveabit/

Right now I'd like to spread the word, gauge interest and hopefully find people with talents, musical or otherwise who would be happy to stream on this channel for the charities we're supporting. If you don't have the bandwidth to stream, a recording is great too and if you need help with that you can even come to my house to record/stream, if you can get to London, England. As long as you have some kind of public face, anyway!

I'll be performing at least one cover-song-concert on the channel, and any events we stream will be recorded, edited if necessary or desirable and streamed on the channel when it's not live, as well as being made available for purchase for BTC (which of course will go to the same charity fund as donations)

So if you want to support these charities, just want some free entertainment or are on the edge of your seats to discover what the madman behind MacMiner actually looks like, please follow this thread for announcements! I'm waiting for the lifestream account to be verified so I can host for more than 50 viewers, which should take around a day, but I'll post here whenever a new event is scheduled.

Hi all,

Just wondering whether anyone would be interested in a second hand electric bike which goes over 10 miles (I went 12.5m to work) and can reach 20mph with the option of using a handlebar throttle or automatic engine startup when you're cycling.

The bike cost £1099 new:
http://www.alienbikes.co.uk/page7.htm

I was using it as a backup for another electric bike so when the primary needed work I could still cycle to work, however I no longer cycle to work. It must have less than 100 miles on the bike and has never had a flat.

There is a chip to the gear changer box on the handle bars but everything works fine.

I have the original box and you can arrange for a courier otherwise you can collect from Petts Wood station.

Just putting a feeler out there, BFL have issued 25% discount vouchers to those who ordered in the first 4 months and valid for less than one month from now. These are not transferable but I'm thinking about placing a discounted order on your behalf and either having it shipped directly to you (if not possible, shipping it on to you when it arrives) or hosting it for you here with my devices at 10% over UK electricity prices for it's power draw.

In the past I set up BitBacco which closed due to lack of sales and Anonymailer which is still up and I make MacMiner (the only native Objective-C Mac GUI mining solution, see my sig) so I have quite a lot to lose in terms of reputation, if you're in London UK I can also meet you if trust is an issue.

Bids can be placed as such:
2 Singles @ $4750+shipping = $248 cut

I may end up using the discount myself, but if there's interest and a good offer you've got it. I'll obviously be looking for the bid with the biggest gap between the total order value and the total order value at list price.

Hi everyone,

I've just set up a p2pool node I'm probably going to offer as an auto-config option in MacMiner, and I'm just testing whether the server I've got it on has enough resources to handle the load, I've got a couple of workers on there but I'd appreciate it if anyone else would give it a shot for a while! The fee is set at 1%

address:
176.58.119.218:9332
password:
your BTC address
username:
anything at all

Please let me know how it goes if you give it a shot!

edit: server is now stable, address has changed to pool.fabulouspanda.co.uk:9332 and fee reduced to 0.5%

I've been making MacMiner for only around 2 months now, and a user recently suggested I set up a pool and auto configuration for it. Having had over 6000 software downloads now, it's too good an idea to pass up, so I'm looking to implement a pool that will auto configure the miner with a BTC address either as a primary or backup pool - with the option not to use the pool at all.

Problems:

Tech requirements - I'm guessing running this on a dedicated ADSL2+ line/spare small server isn't going to satisfy bandwidth/processing requirements not to mention the lack of backup

Software - I want to support stratum and GBT and I'm thinking of using eloipool but I'm not sure whether that's possible without a frontend

Whether I can set up as a 'sub-pool' - for instance have eloipool taking and returning work from eligius.st and taking a 1% cut, until the pool hash rate is high enough to run on it's own

Payout methods (must be no risk to operator), and starting without investing (giving away) BTC before the pool finds it's first block.

Should support BTC and LTC

If anyone can help me with these issues I will reward depending on the return of the pool once set up, and I would consider an offer from an existing pool or someone who can get one set up for me if we can agree on terms but I would most like to retain control of the pool if it's possible without too much investment.

Hey all,

Two codes going from GPUs, each for both games. Bids appreciated!

As always, make sure you know the risks of mining too hard on hardware. I take no responsibility if you burn out your computer (higher risk on iMac, laptops, mini)


Please consider a donation! Even the smallest of donations are appreciated. Total donations to date have been one block erupter usb miner and less than 1 BTC. I have also been hired for support/consultancy so contact me if you have a job in mind. The more donations I receive, the more time I get to spend developing MacMiner!

All the miners are in the View menu:

So I'm developing MacMiner with the intention of supporting all there is to be supported.

But I've hit a few hitches with scrypt/litecoin. It's a 2012 Mac Pro with a 5770 which gets 150-170Mh/s BTC mining, yet with bfgminer using scrypt I get ~5Kh/s from the GPU and 30+Kh/s from the CPU.

So I want to know, are any mac users getting better out of their GPU and if so what's your setup? Should I bother to support scrypt right now?

Hi all,

Some of you may be aware of MacMiner which was launched earlier this month as a poclbm GUI. I've now added a bfgminer backed with support for scrypt etc., but the only easy way to do this was to use an installer package rather than the compressed .app I've been distributing so far.

To alleviate healthy concerns with regards to security, this installer package is signed with my developer ID (you can check the certificate by clicking the lock on the top right of the installer once you've opened it) - it will require admin permissions to install jansson and libusb in /usr/ folders, so it will ask for your password.

If you just want the poclbm support you can customise the install to skip the libraries, or just grab the .app from the original thread here:
thread: https://bitcointalk.org/index.php?topic=166347.0
download: http://fabulouspanda.co.uk/macminer/


But I'd really like some feedback on whether the bfgminer backend works for you. I've only tested on the machine I'm developing on and a VM, which lacks devices to mine with. To use bfgminer you'll have to open the preferences (from the MacMiner menu bar or cmd-,) and choose bfgminer, and for now it'll give you an error unless you use flags(options) - if you don't want any special flags you can just use -q (quiet) to minimise the hefty output it churns out. Or check out the available options on the bfgminer github: https://github.com/luke-jr/bfgminer

Here's the installer:
redacted

all downloads require Mountain Lion (Mac OS 10.7+ )

The last one was from 2011 so I figured perhaps someone would appreciate a binary of a the latest version (with stratum support) to get mining without having to drop down to the command line and install some dependencies…

http://fabulouspanda.co.uk/guiminer/guiminer.app.zip (requires 10.8 )

edit: or try my new native mac GUI - choose from poclbm, bfgminer or cpuminer for scrypt in the 'View' menu:
http://fabulouspanda.co.uk/MacMiner10.8-1.0.2.pkg (Mac OS 10.8 )

http://fabulouspanda.co.uk/MacMiner10.7-1.0.2.pkg (Mac OS 10.7)

^Both signed with my developer ID. always get the app from fabulouspanda.co.uk or the github: https://github.com/fabulouspanda/MacMiner
(I recommend MacMiner as it doesn't require a force quit and you can stop the poclbm process without using activity monitor - although currently if you don't stop it before you quit you still need to do it that way - it won't keep mining once you've quit, but having several instances of poclbm running idle bugs me personally. Will update to stop on quit soon.)

Known issues: if you don't press 'stop' on any miner you start in the app, they keep running after you quit and need taking care of in Activity Monitor (in your utilities folder)

Notes: While I find poclbm is very good at finding the right operating temperature on a MBP with default settings, I take no responsibility if you overheat your computer with this software! Don't blame me if you set the intensity high up and it burns out your graphics card! My 17"MBP doesn't seem to have a problem with it (in cold english winter weather) but if your GPU is less tolerant of heat (specific tolerances vary even with the same models) it could potentially burn out your gpu, and at least one person on the board has reported leaving a work iMac running a miner overnight and finding the gpu non-functional the next day. Don't push it too hard!

My account is named after a service I unfortunately closed due to lack of business, can I change it to reflect my new service?

Hi all,

I'm starting a new service whereby I'll post a letter (up to 2 sides of A4 paper) on your behalf from the UK to anywhere in the world. This can be anonymous, or not, depending on your preference. If you provide an email address you will receive confirmation and a tracking address for your letter. Why not give it a shot?

Let me know if you have any questions or feedback!

Hi people,

Back from semi/possible/something-like-retirement here having closed shop a few months ago probably more than temporarily to make this scam alert. Title says it all really. Sorry guys! To be honest I would have thought you'd need some kind of verification to get listed on there... If they want to hand the deeds or whatever there is on GLBSE to me I'll happily not kill the stock, but like I say, I'm not all that likely to open shop in the next month or two at the very least…

In memoriam of Bitcoin's first tobacconist   

Tonight's programme featured a section on the dark net, clearly using a press statement from the police as source material...

They highlighted Bitcoin as an 'anonymous' 'untraceable' currency used by traffickers of illegal goods. (A bit late to the misinformation party right?)

I've made a politely worded corrective complaint and request for a correction on tomorrow's show. Maybe a few more would make it a little more likely!

walletbit have now created the only functioning opencart plugin, so their customers can now pay their bills at checkout instead of waiting for manual confirmation! Thanks guys! A very good sign of things to come. Merchants rejoice 

I'm afraid you do need a walletbit account to use this feature, but you can still order manually until your preferred method of payment is supported by opencart plugin.

Happy shopping!

Hi all,

Despite the relatively high cost of tobacco in the UK, I've had a reasonable amount of interest in shipping to the USA (which looks like a bit of a legal quagmire to me)

But I got to thinking, if someone was to use a mail forwarding service such as:
http://www.londonpresence.com/mail.php

There would be no problems from my point of view right? Legally or otherwise - as I wouldn't be the one shipping internationally. It would be as though you bought the products here on holiday, and took them home with you?

I'm also curious whether I'd run in to problems with customers receiving import tax charges on delivery.

Can anyone enlighten me at all?
