Rosewill IDE USB 2.0 external enclosure

Got this from newegg. It is the Rosewill RX35MV-U-BU SLV 3.5" IDE to USB 2.0 External Enclosure (Silver Aluminum & plastic). If you have an old hard disk drive (HDD) hanging about and it works and you want to convert it into external storage - give this a try.

Be aware that the design is iffy and the IDE connector pins that stick out from underneath the PCB may touch the aluminium case - I put two layers of duct tape strips to ensure isolation between the data pins/power and the case body per chance pressure on the case caused the aluminum body to short the power or data pins.

The standoffs between the drive and the enclosure are plastic, which doesn't make for such efficient heat conduction even though the body is aluminum.

The drive was easy and intuitive to assemble - took about 10 minutes. Vista has no problem recognizing and treating the enclosure as an external drive.

This is an IDE USB 2.0 device, IDE drives are going out of fashion now, being replaced by SATA

As a sample transfer speed I got a peak transfer rate of 18.9 MB/s (transferred 1.46 GB in about 2 min). The HDD was a Western Digital Caviar SE WD1600JB 160GB 7200 RPM IDE Ultra ATA100.

Flowing text in inkscape (Poster making)

You can flow text into arbitrary shapes in inkscape. (From a hint here).

You simply create a text box, type your text into it, create a frame with some drawing tool, select both the text box and the frame (click and shift) and then go to text->flow into frame.


The omnipresent anonymous asked:
Trying to enter sentence so that text forms the number three...any ideas?
The solution:
Type '3' using the text toolConvert to path using object->pathSize as necessaryRemove fillUngroupType in actual text in new text boxSelect the text and the '3' pathFlow the text

Pandas panel = collection of tables/data frames aligned by index and column

Pandas panel provides a nice way to collect related data frames together while maintaining correspondence between the index and column values:

import pandas as pd, pylab #Full dimensions of a slice of our panel index = ['1','2','3','4'] #major_index columns = ['a','b','c'] #minor_index df = pd.DataFrame(pylab.randn(4,3),columns=columns,index=index) #A full slice of the panel df2 = pd.DataFrame(pylab.randn(3,2),columns=['a','c'],index=['1','3','4']) #A partial slice df3 = pd.DataFrame(pylab.randn(2,2),columns=['a','b'],index=['2','4']) #Another partial slice df4 = pd.DataFrame(pylab.randn(2,2),columns=['d','e'],index=['5','6']) #Partial slice with a new column and index pn = pd.Panel({'A': df}) pn['B'] = df2 pn['C'] = df3 pn['D'] = df4 for key in pn.items: print pn[key] -> output …

Drawing circles using matplotlib

Use the pylab.Circle command

import pylab #Imports matplotlib and a host of other useful modules cir1 = pylab.Circle((0,0), radius=0.75, fc='y') #Creates a patch that looks like a circle (fc= face color) cir2 = pylab.Circle((.5,.5), radius=0.25, alpha =.2, fc='b') #Repeat (alpha=.2 means make it very translucent) ax = pylab.axes(aspect=1) #Creates empty axes (aspect=1 means scale things so that circles look like circles) ax.add_patch(cir1) #Grab the current axes, add the patch to it ax.add_patch(cir2) #Repeat
