I don't think the price should exceed 200$, and the "dedicated" means that box should only keep blockchain and run the latest daemon. All other services should run outside the box, as they are able to communicate with daemon over TCP/IP network, aren't they? Perhaps there are security or performance issues in TCP/IP versus shared memory, I don't know. I assume, when running daemon and "service" on the same LAN subnet, it should work OK.

Well yeah, using SSD might be an exaggeration. My own testing showed that starting exiting daemon on SSD is way faster that on regular drive. So when you need to do some daemon maintenance, SSD should reduce the downtime. In regular operations (in my case, one wallet communicating with daemon  ), indeed, there is no difference between drive types.

I set up a new computer (Ubuntu server 14.04) and started the command:


It worked for a long time till I saw an error:
monero -> fatal error  db_cxx.h missing

In the directory bitmonero/build release/bin/ I find these files:


I found that the ~/.bitmonero directory was empty.
With: wget -O blockchain.bin http://monero.cc/downloads/blockchain/linux/blockchain.bin
I could get the blockchain.bin (4530181601).

When I try to start ./bitmonerod I get the following error:
~/bitmonero/build/release/bin$ ./bitmonerod
Creating the logger system

What does it mean, how to fix?

I get:
~/bitmonero/build/release/bin$ ./simplewallet
Creating the logger system
terminate called after throwing an instance of 'std::runtime_error'
  what():  locale::facet::_S_create_c_locale name not valid
Aborted (core dumped)

- I guess that is a followup error from not running bitmonerod.

Looks like make exited with the error you described above. Try installing the Berkeley database libraries for C++ and run the script again.

If Monero goes "anywhere", 1 TB will likely not be enough space in 10 years.

No fan lasts that long. I'm woundering if a http://uk.wikipedia.org/wiki/%D0%95%D0%BB%D0%B5%D0%BC%D0%B5%D0%BD%D1%82_%D0%9F%D0%B5%D0%BB%D1%8C%D1%82%D1%8C%D1%94 could do the trick of cooling down the hot spot whilest recovering some electrical energy. Recuperation. Tesla cars do more of that than my car has denoted total capacity.

Don't know why Whikipedia doesn't feature english translations on http://en.wikipedia.org/wiki/Jean_Charles_Athanase_Peltier work.

Just curious.. is an AMD Athlon a "really cheap" CPU that won't be as efficient?  I'm currently in the process of learning Ubuntu and the command line systems, and was wondering if it would be worth it to put my hashing power towards XMR, or just go for AEON?

I would imagine, all the coins will pool together in a block and then mix all of it.  Afterwards, send the coins to the corresponding parties each sender wants to send too. It wouldn't necessarily matter how many coins are being sent, and wouldn't need to know how much coins you are mixing with...  I think that's the just of it, if I read into it right...

That's the same or likely better (since you also have to add the rest of the system overhead for the GPU system) efficiency for the CPU without the need for fans and a second device (size, assembly effort, etc). It is half the total hash rate, but that isn't really huge difference in terms of making a contribution to the network with a low-maint, cheap-to-operate device. Personally I'd rather have something that sits there completely silent for 10 years with zero attention from me than twice the hash rate. If I want more hash I can buy two. But I agree that is a value judgement.

Still it is hard to build that for an attractive price point <$300, so kind of irrelevant right now.


I doubt you can get 33 W GPU, CPU, HD, etc in a box with no fan. I don't even know whether the GPU can run fanless on its own. If I search for fanless 750-ti all I see are water cooled things (EDIT: I found some with heat pipes and massive heat sinks, but you still have to remove the heat from the box). Though maybe the low power usage of cryptonight mining means a custom built low-efficiency cooling solution could work. I still doubt you will get it in a box. The best you can likely achieve is a well designed box with one quality, relatively expensive, fan (which might last several years) that draws air across multiple devices for cooling. Even that would be a nice design accomplishment.


I think you can get some high efficiency CPUs that are on raw boards or possibly even socketed where you can design and build your own box. When I've looked for that I've generally found them even more expensive though, so I disregarded it.

i friggin hate reddit sometimes. Impossible to easily find where the latest is on that friggin thread.

we shall see. I'm close. I finally got the slew of M3X0.50 screws in to mount everything and some nylon washers. Thank god (or, well, humanity, or specifically whatsisface that runs wikipedia) for the wikipedia computer mounting screws page.

I neglected to mention that I have at least 2 750 ti boards where the manufacture fan assembly has been removed, because the configuration of the pci-eX1 next to the pcieX16 makes it impossible to get a riser in between with that bulky thing. With a fan just blowing over the area, its at a comfortable 53C, which is about 8C over a card with the fan still on them.

though im really tempted to just flip the orientation of the GPU card, cut a hole in the case, and cement on one of them copper dell server heatsinks.
