Software developer (in love with C++). Hardware geek (FPGA's, STM32, AVR, crazy stuff from discrete components), love LED indicators (7-segment, alphanumeric). Trying to understand ASIC design & manufacturing better at the moment. Also, trying to wrap my head around lens design, but that is not going to be that easy.

comment What causes this IR emission in UV 365nm LED?
@boyfarrell You was right, apparently strong signals make sensor non-linear, so software processing was removing harmonics not perfectly.

It seems harmonic suppression is in software? Due to different sensitivity between IR and UV strong signals might saturate the sensor and make correct software processing impossible...

It appears there is indeed significant non-linearities involved when suppressing strong harmonics. Weaker signal somehow does not produce this "ghost" IR...

That was quite unusual... I was able to replicate the situation where IR peak was removed by IR-cut filter, but IR-pass (680nm+) filter does not show anything behind it...

comment What causes this IR emission in UV 365nm LED?
Physics of 1064nm and 808nm leakage in 532nm lasers is completely clear to me (808nm diode pump, 1064nm from Nd:YVO4 not converted by non-linear crystal). In this case there is an LED, not a laser, so I am in doubt there might be something similar.

That is definitely a step forward (comparing to Samba), but it seems it still does not allow to enable client-side read caching. Write caching is nice though.

comment Windows - mount network drive with client-side read/write caching from Linux storage server
@TonyHinkle You right, currently I am using Samba, but obviously windows client does not cache anything in this case. I was about to test Microsoft iSCSI initiator with iSCSI target on Ubuntu server - but found no mentions in the Internet on whether Microsoft iSCSI initiator allows to use cache. Maybe wrong keywords.

comment How to do live updating similar to Google Docs?
@JithinJose WebSockets are surely better, but were not available in 2010 :-D
