How to see a Skype’s user location in the map

You can discover the location of an online Skype user using this approach:

1) Verify if the user is really online;

2) Go to and put the Skype user name;

3) It will return: Resolved IP: (2156ms);

4) Go to and put this Resolved IP number in the “Try our GeoIP2 Precision service demo:” text box and click on “GO”.

5) It will return a Lat/Long position like this: -23.5475, -46.6361

6) Just search for this lat/long on Google and it will return the map position.

Very easy!

Update: The position is not precise, it is approximate. It should be probably the “last mile” position from your ISP.

Payoneer not that easy as supposed to be

Payoneer motto is: “The Easy Way to Send & Receive Money”

But unfortunately it is not…

I was trying to add my Payoneer “US Payment Service” bank account to Paypal, but was receiving this error message:

Sorry, we’re unable to link that bank because it is disabled. Please try another bank.

The Payoneer Bank Name was: “First Century Bank”.

After two days explaining the issue to Payoneer finally they fixed it and sent me an email: “As requested, USDVirtual Bank Account Service Created”

They created a new Bank account, this time the Bank Name is: “Community Federal Savings Bank”.

Then I added it to Paypal and it worked correctly. I’m posting this information to help other people that could face this same issue.

Thanks Payoneer for fixing this issue.

NuttX low power modes

The NuttX power management has four levels or modes (from include/nuttx/power/pm.h):

The normal, full power operating mode.

This is still basically normal operational mode, the system is,
however, IDLE and some simple steps to reduce power consumption
provided that they do not interfere with normal Operation.
Simply dimming a backlight might be an example something that
would be done when the system is idle.

Standby is a lower power consumption mode that may involve more
extensive power management steps such has disabling clocking or
setting the processor into reduced power consumption modes. In
this state, the system should still be able to resume normal
activity almost immediately.

The lowest power consumption mode. The most drastic power
reduction measures possible should be taken in this state. It
may require some time to get back to normal operation from
SLEEP (some MCUs may even require going through reset).

How to update the OpenBench Logic Sniffer’s firmware

First you need to download firmware updater software from here:

Press the UPDATE and RESET buttons of OpenBench board, release RESET button wait 2 seconds and finally release UPDATE button.

Then follow these steps:

$ tar xvf ols-0308-expert.tgz
$ cd ols-0308/OLS_Upgrader/
$ sudo ./

Unfortunately I got this error:

ols-fw-update: error while loading shared libraries: cannot open shared object file: No such file or directory
Press any key to continue...

I tried to create a symbolic link to x86_64 but got this error:

ols-fw-update: error while loading shared libraries: wrong ELF class: ELFCLASS64
Press any key to continue...

Then I figured out I need to install the libusb for i386:

$ apt-get install libusb-0.1-4:i386

Finally the update worked fine.

The tip to fix the libusb I found here:
