NXT :: descendant of Bitcoin - Updated Information

[sherpico77]

Sorry for posting this here, but it realtes to Nxt, too.

Is there a remote desktop application for android available? I would like to access my Cubietruck (with android on it) and see the "desktop" like I am used to it with Teamviewer. Is it possible? Or should I install linux? Is it possible with linux? What sw to use? I would like to use my Cubietruck as an Nxt node AND as a media box.

Good point. I'm interested too.

@CFB: I seem to be missing an API call with which I can pull information on the assets that an account acutally owns. It can hardly be possible to keep track of the inventory in a client app - if s.t. happens to that one single particular device, the entire stock is lost!?! And the whole concept of nxt is decentralization anyway...

How do I query ownership of assets? Is it not in yet, or am I overlooking s.t. obvious?  

I'll add this API.

I use VNC Viewer Lite on my Nexus.  It can be had from the Play store.

Oh, nvm.  Misread that.

Let me tell you all how linux desktop environments SUCK BALLZ

j*sushti*tyfu*kingc*rist

WTF linux?

Now Ive used unix/linux/freebsd for years and years.  Yes I am one of the few people who can actually say they've used 'real' unix.  I used to run an AT&T 5ess central office switch.  anyways, I also used to use openbsd desktop environment, successfully I might add, and have also run lots of misc little app/servers on freebsd/solaris.

so it not like Im some dumb tard off the street trying to try linux.

what is this BULLSHIT ubuntu 'unity' WM or X server or whatever the hell it is?  dammit when I ln -s something to ~/Desktop and the target is a bash script I FUCKING EXPECT TO BE ABLE TO RUN THE GODDAM SHELL SCRIPT!!!!  WTFFFFFF?

why does it always automatically mount my windows partition?  hell i manually unmount it and a few minutes later there it is again.

OK unity sucks.  so I found some instructions to change to gnome

ITS WORSE.  now NOTHING shows on my desktop!  I cannot even find an app list of stuff similar to windows start.

WTF linux why must you suck so bad?

PoW's Negative Ecological Consequences

Confirming transactions for existing Bitcoins, and creating new Bitcoins to go into circulation, requires enormous background computing power that must operate continuously.  This computing power is provided by so-called "mining rigs" operated by "miners".  Bitcoin miners compete among themselves to add the next transaction block to the overall Bitcoin blockchain.  This is done by "hashing" - bundling all Bitcoin transactions occurring over the past ten minutes and trying to encrypt them into a block of data that also coincidentally has a certain number of consecutive zeros in it.  Most trial blocks generated by a miner's hashing effort don't have this target number of zeros, so they make a slight change and try again.  A billion attempts to find this "winning" block is called a "gigahash", with a mining rig being rated by how many gigahashes it can perform in a second, denoted by "GH/sec".   A winning miner who is first to generate the next needle-in-a-haystack, cryptographically-correct Bitcoin block receives a reward of 50 newly-mined Bitcoins - a reward worth, at the time of this writing, around $50,000.   This competition among miners, with its hefty reward, repeats itself over and over and over every ten minutes or so - by early 2014 generating rewards of over 7000 bitcoins per day worth around $7 million dollars per day.

With so much money at stake, miners have supported a blistering arms race in mining rig technology to better their odds of winning.  Originally Bitcoins were mined using the central processing unit (CPU) of a typical desktop computer.  Then the specialized graphics processing unit (GPU) chips in high-end video cards were used to increase speeds.   Field programmable gate array (FPGA) chips were pressed into service next, followed by mining rigs specialized application specific integrated circuits (ASIC) chips.  ASIC technology is the top of the line for Bitcoin miners, but the arms race continues with various generations of ASIC chips now coming into service.  The current generation of ASIC chips are the so-called 65nm units, based on the size of their microscopic transistors in nanometers.  These are due to be replaced by 28nm ASICs in early-2014 and 20nm units by mid-2014.   An example of an upcoming state-of-the-art mining rig would be a Butterfly Labs "Monarch" 28nm ASIC card, which is to provide 600GH/sec for an electricity consumption of 350 watts and a price of $2100.  On the horizon is a card from Hashblaster slated to have three 20nm ASIC chips providing 3300 GH/sec for 1800 watts of power consumption.  Most operational mining rigs will probably be upgraded to this standard of performance and efficiency by mid-2014.

The mining rig infrastructure currently in place to support ongoing Bitcoin operations is astounding.  Bitcoin ASICs are idiot savants - they are able to do only the Bitcoin block calculation and nothing more, but they can do that one calculation at supercomputer speeds.  In November 2013, Forbes magazine ran an article entitled, "Global Bitcoin Computing Power Now 256 Times Faster Than Top 500 Supercomputers, Combined!".  In mid January 2014, statistics maintained at blockchain.info showed that ongoing support of Bitcoin operations required a continuous hash rate of around 18 million GH/sec.  During an day of 86,400 seconds, this means around 1.5 trillion trial blocks were generated and rejected by Bitcoin miners looking for the magic 144 blocks that would net them $7 million.  Thus around 99.99999999 % of all Bitcoin computation go not to curing cancer by modeling DNA or searching for radio signals from E.T - instead, they are totally wasted computations.  

The power and cost involved in this wasteful background miner support of Bitcoin is enormous.  If all Bitcoin mining rigs had "Monarch" levels of capability as described above - which they will not, until they are upgraded - they would represent a pool of 30,000 machines costing over $63 million and consuming over 10 megawatts of continuous power while running up an electricity bill of over $3.5 million per day.  The real numbers are significantly higher for the current, less-efficient mining rig pool of machines actually supporting Bitcoin today.  And these numbers are currently headed upward in an exponential growth curve as Bitcoin marches from its current one transaction per second to its current maximum of seven transactions per second.

There are at least 4000 network nodes at this time.

I actually used incorrect Bitcoin numbers, the current reward is 25 Bitcoins per block, not 50.  So it should be :

A winning miner who is first to generate the next needle-in-a-haystack, cryptographically-correct Bitcoin block receives a reward of 25 newly-mined Bitcoins - a reward worth, at the time of this writing, around $25,000.   This competition among miners, with its hefty reward, repeats itself over and over and over every ten minutes or so - by early 2014 generating rewards of over 3500 bitcoins per day worth around $3.5 million dollars per day....During an day of 86,400 seconds, this means around 750 billion trial blocks were generated and rejected by Bitcoin miners looking for the magic 144 blocks that would net them $3.5 million...

So basically the daily reward is currently roughly equal to the daily electricity cost.  I think the only way Bitcoin mining is profitable is if you are somehow getting cheap/free electricity by running it on somebody else's grid without them being aware of it...

What my dad and I did to offset this was capture the heat from the mining rigs and duct it into the return of the furnace. Being able to never turn the furnace on during winter in Iowa offsets cost a lot. In the summer, we duct it out the chimney.

meh. its actually ubuntu 'UNITY' thats the culprit. I prefer debian with fluxbox, but Ubuntu with GNOME classic sort of half behaves. But I've had bad experience with Unity also. Slippery slope Master Shuttleworth is on there ..

[davethetrousers]

OK unity sucks.  so I found some instructions to change to gnome

Relax, take a cookie, listen to me

First off, you're right, Unity is the great Satan. But leave GNOME itself out of that judgment. A nicely config'd GNOME handles like a dream.

That stuff you are missing you can get when you open https://extensions.gnome.org/ in a browser. There you can load all kinds of stuff. Or just do it like it's meant to, use the activities menu to start/find stuff (northwest corner / windows key).

[EvilDave]

btw here are our last papers about this, any comment would be fantastic, we still didn't make all maths

The cost to run the network mostly depends upon the amount of electricity it uses

I see the biggest cost to running the Bitcoin and Nextcoin networks to be the electricity ..........cut this down to size.

+1's all round.

On the Amsterdam Bitcoin conference front, I've still heard nothing back from the organisers of the March 18-20 event.
Sent 3 mails so far, but nada. No telephone nr available.
So if I've still heard nothing by Friday, I'm going to assume that it's simply not happening.
http://www.bitcoinference.com/

Moving onwards, I'm in the process of getting a mail together for Jinyoung at the Bitcoin Foundation for their conference, May 15-17:
https://bitcoinfoundation.org/forum/index.php?/topic/652-bitcoin2014-l-may-15-17-l-amsterdam/

Any ideas about what we actually want to do at the conference?
I'm assuming a stand (with solar powered RaspPi forging away, +10) promo material and team, but how about speakers/seminars ?
This conference is (almost) definitely going to happen, so we need to get moving on it.

If u have any ideas or feedback, post on:

https://nextcoin.org/index.php/topic,2277.0.html



On to my last brilliant idea for today:

I'm trying to figure out how practical it would be to make NXT completely green by offsetting carbon emissions.
The basic outline of my idea is to have a dedicated fund , maybe from unclaimed coins, that is able to forge enough NXT to pay for a carbon offset program, for the parts of the NXT network that aren't solar powered.  (Brilliant set-up, btw, people are gonna love it)
Again, throw some ideas my way on:

just go to fluxbox. Acutally, gnome sucks also. What the icons on your desktop are is simply a permanently running file manager. if you really want to have icons on the desktop, there is a little extra app for that too.
you have to tune a few things yourself, but it is lightning fast

[davethetrousers]

just go to fluxbox

Nah, KDE all the way

Good idea, so you're not mistafreezing any more.

I wouldn't be if I lived with my parents, I don't have $20,000 in Bitcoin rigs!! I'm still freezing in my house, lol.

Personal account management showing NXT values in other currencies



Be careful with the market view, though. You know, it's closed source and I might have something in there that influences the markets in the direction I want...  

[gimre]

So, quick question.  Say you are making a random new NXT password using 2 thru 9, a thru k, m thru n and p thru z so a field of 32 characters. What is the length of such a password to achieve maximum entropy /security, where adding one or more additional characters buys you no additional security?

that is an easy one. 100 digits, because all digits after that are ignored

Little less, you'll get maximum entropy with 32 symbols, but the thing is, the question is ill formed.

Consider one of strings over this alphabet:
23456789abcdefghijkmnpqrstuvwxyz

does it look secure to you?

RaspNXT - a standalone NXT environment for the Raspberry Pi

Thanks for your work davethetrousers!

I just modified your run_nxt.sh to be more raspian frendly with some log messages and to enable system startup and stop. It monitors the log file at start or stop of the server and logs it in the start/stop message. Just copy it to /etc/init.d and run "sudo update-rc.d run_nxt.sh defaults". It will start and stop in the runlevels and it will wait on "stop" untill blockchain is saved (timeout 10m).

Please make sure to setup the variables like directorys and such. This is tested only with 0.5.9 and if a next update changes the log output, this script have to be changed!

Code:

#! /bin/bash
...

I hope its useful for someone. If someone finds bugs or something stupid, please let me know, I'm not an expert! ;o)

greets
eb

great stuff, thank you very much ebereon, that's an awesome script, just what i needed!
dave: you should really add it to RaspNXT
