If you want to use GSM/3G/LTE modem on your FreeBSD box you need to use PPP and following configuration:

 set log Phase Chat LCP IPCP CCP tun command
 ident user-ppp VERSION 
 set device /dev/cuaU0
 set phone *99\#
 set redial 5 10
 set speed 115200
           \"\" ATH OK ATZ OK AT OK-AT-OK ATE1Q0 OK \
           AT+CFUN=1 OK-AT-OK \
           AT+CPIN? READY-AT+CPIN=\"1234\"-OK \
           AT+CGDCONT=1,\"ip\",\"internet\" OK \
           \\dATDT\\T TIMEOUT 40 CONNECT"
 set timeout 10
 enable dns
 set ifaddr
 add default HISADDR

In case you need to list directories only in reverse recursive order for automatic list generation for directory removal on package deinstallation, here goes an example sh+find script that should work on all Unix platforms:

while [ $dirlevel -gt 0 ]; do
 find /tmp -type d -depth $dirlevel
 dirlevel=`expr $dirlevel - 1`;

Q: How to change the default boot menu entry in GRUB2 used widely on Linux systems?

A: You can do it easily as root in three following steps:

  1. Run update-grub program and copy entry name that you want to make default.
  2. Edit /etc/default/grub and add or modify existing GRUB_DEFAULT="your_menu_entry_here".
  3. Run update-grub program again to update the grub bootloader configuration.

In my first steps of mass production I have created a simple simulation of unit cost per production volume. On the plot we can see a price for two version of the final product – basic and full featured.


Looks interesting, as components cost highly depends on the order volume, prices can go down when purchasing more and manufacturing more – so called scale effect can bring more products for a lower price per unit. Next step is to negotiate better prices in high volume orders and choose between different distributors, then try the automated machine manufacturing..

Heimdall is an Open-Source utility to work with Android devices manufactured by Samsung. It allows to flash firmware components into memory via FastBoot/ODIN+USB. I have created a patch to build this nice tool on FreeBSD OS (QT gui works as well, to build it you need qt-{gui,qmake,uic,moc,rcc,…} packages installed). When patch is included into the project sources and release is done, I will prepare a FreeBSD port for this nice utility which is only missing a memory dump and live boot to be totally perfect :-)


“If the number of distinguishible states is a must, but not enough, for a consciousness to exist [1] in a machine, there must be additional structural factor for consciousness to exist. Given human, biological DNA-based self replicating machine, has this consciousness operational, it is possible to assume that the universe is conscious as well, because there is a sufficient number of interacting bodies, just as in our neural network, and we are all made of the same star dust. We Are The Universe! :-)”/CeDeROM2013

Today I had a pleasure to give a lecture on my “CeDeROM Brain Computer Interface” at Bio-Tech 2013 scientific conference hosted by Lublin University of Technology. Thank you for this great opportunity and so many interesting people!

I am happy to announce a new release of LibSWD-0.6! Most important feature of this release is the standalone Application with an example of Command Line Interface (CLI), FTDI driver and ARM Cortex-M3 Core Debug and Flash support demonstration. Please report issues via Ticket System. Have fun! :-)
