“Money printer”

Hi
I’m working on a python script which uses a cascaded triangular arbitrash in order to multiply money.
But so far the calculations seem to be all unsatisfying.

What I’m doing so far is fetching and filtering and interpolating the values in order to estimate the trade development:

#!/usr/bin/python
import sys
import os
import copy
import math

# delays:
from time import sleep

# web api
from Cryptsy import Api

#plotting the stuff
import matplotlib
matplotlib.use("TkAgg")
from matplotlib.pyplot import plot
from matplotlib.pyplot import figure
from matplotlib.pyplot import close
from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg, NavigationToolbar2TkAgg
from IPython import display

#numpy stuff:

from sklearn.linear_model import LinearRegression
from sklearn.isotonic import IsotonicRegression
from sklearn.cross_validation import cross_val_predict
from sklearn.preprocessing import PolynomialFeatures
from sklearn.pipeline import Pipeline
from sklearn.utils import check_random_state

#pyqt fit
from pyqt_fit import npr_methods
import pyqt_fit.nonparam_regression as smooth

	x = linspace(1, len(price_array), len(price_array))
	y = array(price_array)
	filtered_y = savgol_filter(y, window_length, savgol_filter_polyorder)

	k0 = smooth.NonParamRegression(x, filtered_y, method=npr_methods.LocalPolynomialKernel(q=gauss_poly_deg))
	k0.fit()
	z = k0(x)

	avg_diff_number=len(x)/4

	new_x=x[len(x)-avg_diff_number-1:]
	new_z=z[len(z)-avg_diff_number-1:]
	clf = LinearRegression()
	clf.fit(new_x[:,newaxis],new_z)
	tangent=clf.predict(new_x[:,newaxis])

	num_different=(tangent[-1]-tangent[0])/(new_x[-1]-new_x[0])

If someone has a better idea: Please say so!

Two grakas, three displays… and X.org >.<'

Hi folks
This one looks easy… X.org should just detect it, right?

dizzy-6:/home/leviathan # lspci | grep VGA
01:00.0 VGA compatible controller: NVIDIA Corporation GT200b [GeForce GTX 275] (rev a1)
02:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Caicos [Radeon HD 6450/7450/8450]

Well… It didn’t. It had to tinker a whole day until I got the right xorg.conf
I figured I share it with you:

Using gamma ray as energy source?

A friend asked me a question on how feasible it would be to use gamma rays as an energy source. So let’s crunch some numbers: The wavelength of gamma rays is
\[\lambda=\frac{c}{f}=0.005 nm\]
Since the optimum length l for an antenna is
\[l=\frac{\lambda}{4}=0.00125 nm=1.25 pm\]
We are a bit in trouble here since the radius of the atom Sodium for instance is approximately 160 pm.
Physically it’s just not possible to build such a small antenna.

My trip to China (Chapter 4)

Today… Let’s just say: I’ve found the StarBucks.
It’s exactly as the StarBucks in Switzerland. I mean exactly the same.
Only that an Americano middle sized cup (for take away) is only 3.50 CHFr and not 5.00 CHFr.! ^_^

Agricultural paradise

Well… I didn’t find it in time… Also as far as I could see… It’s not really as interesting as some travelling blogs have described it.

Lovers road

Well. I didn’t go straight there either because I was stuck at the bubble tea and steamed bread corner where I’ve found fresh Manju (with red bean stuffing! *_*) as you can find a recipe for on my blog.
Also I’ve found Banh Bao… After this dinner I was so stuffed that I decided to roll back home.
Ahh! I talked Chinese a lot more today ^_^

Park in Zhuhai (珠海)

Actually just one of so many parks in 珠海. I passed by this place on my way to the 客车68号 (Bus number 68) to the office of Allwinner Technology.

My way to Allwinner Technology

Since the security guard at the entrance already looked a bit confused when I sat down and tried to make clear to him with my dictionary that I was two hours too early for the meeting I’ve let it be to make pictures of the entrance.
Just be told, that the company has a beautiful modern new building now with leather seats and mings vases and two big red Chinese lanterns at the entrance.
A beautiful office building! *_*

Dinner (sponsored by Allwinner)

Best food of my life (2.0)! ^^
我不想回来瑞士! (I don’t wanna go back to Switzerland) *_*

Ah and btw, maybe I don’t have to.
I seems as if the dinner has brought up some additional business ideas which would justify my employment at their company =D

Lost clothes

Thanks to the Russian duty and tax office my clothes are still all in Moscow, which forced me to buy new ones at the stores around the corner (first pic). Actually it’s not such a problem I guess, I think I look quiet good in these 0.30$ clothes ^^ (second pic) 20150131_18451820150131_192221

Food

After having had some trouble making myself understood I managed to get my favourite food after all. 20150201_183602

Current mirror

Given, a complicated darlington circuitry:
darlington
We now replace the darlington pairs with single NPN transistors by defining: $$I_C=I_B \cdot a$$ with $$a=(\beta+1)\cdot\beta$$ and $$I_E=I_B \cdot b$$ with $$b=(\beta+1)^2$$
darlington_replacement

Now we set:
$$I_{KD} = I_{B1} + I_{C3} = I_{B1} + I_{B3} \cdot a$$ and $$I_{RL}=I_{C4}=I_{B4}\cdot a$$ and $$I_{B2}=I_{B5}$$ and $$I_{KD} + I_{C1} + I_{RL} = I_{E5} + I_{E2} $$
$$I_{KD} + I_{B1} \cdot a + I_{RL} = I_{B5} \cdot b + I_{B2} \cdot b = 2\cdot I_{B5}\cdot b = 2\cdot I_{B2}\cdot b$$
$$\Rightarrow I_{RL}=- a \cdot I_{KD} – I_{KD} + a^2 \cdot I_{B3} + 2 \cdot b \cdot I_{B2}$$

And resolve the current equation:
$$I_{B3} \cdot b = I_{E3} = I_{C5}+I_{B2}+I_{B5}$$
$$=I_{C5}+2 \cdot I_{B2}$$
$$=I_{C5}+2 \cdot I_{B5}$$
$$=a \cdot I_{B5}+2 \cdot I_{B5}=(a+2)\cdot I_{B5}=(a+2)\cdot I_{B2}$$

$$\Rightarrow I_{B2} = I_{B5} = \frac{1}{a+2} \cdot I_{E3} =\frac{b}{a+2} \cdot I_{B3}$$
$$I_{E1} = I_{B1} \cdot b = I_{B3}+I_{B4}$$

$$I_{C2} = I_{B2} \cdot a$$
$$= I_{E4}=I_{B4} \cdot b$$
$$\Rightarrow I_{B4} = \frac{a}{b}\cdot I_{B2}=\frac{a}{b}\cdot\frac{b}{a+2} \cdot I_{B3}$$

$$I_{RL}=\frac{a^2 b}{a^2 b + 2 a b +2}$$
