Sometimes you need to perform a network installation (i.e. when no USB or DVD drive is allowed to boot, but you can boot PXE). In case of FreeBSD you can use DNSMASQ to serve the DHCP that will assign the initial client address and configuration along with PXE boot image served over tFTP. At this point you will have bootloader running, so you can serve filesystem over NFS to obtain working environment and/or the installer..

  • Create a directory that will hold the target filesystem over network. In my case that was
    /usr/local/tftp/FreeBSD
  • Put OS/Installer files inside above directory
    cd /usr/local/tftp/FreeBSD
    wget http://(..)/file.iso
    7z x file.iso
  • Edit /etc/exports to export the filesystem over NFS
    /usr/local/tftp/FreeBSD -ro -alldirs -network 192.168.0.0
  • Install the dnsmasq
    pkg install dnsmasq
  • Setup the /usr/local/etc/dnsmasq.conf
    enable-tftp
    tftp-root=/usr/local/tftp/FreeBSD
    
    dhcp-range=192.168.0.50,192.168.0.60,255.255.255.0,1h
    dhcp-boot=boot/pxeboot
    dhcp-option=option:router,
    dhcp-option=option:root-path,/usr/local/tftp/FreeBSD
    
  • Restart services
    service nfsd onerestart
    service dnsmasq onerestart
  • In case you get bootloader running but troubles with NFS make sure that mountd is running. Also you can see who is using the NFS shares with
    showmount -a

PXE Boot always use initial DHCP/tFTP to fetch configuration and bootloader, so the first stage is similar and should work with other Operating Systems and Bootloaders as well, the rest is up to bootloader itself..

It is my great pleasure to inform you folks that, almost after four years, I did a new release of LibSWD-0.7 [1], a low-level embedded systems access open framework. Special thanks goes to Andrew Parlane of Carallon Ltd [2] for his much appreciated contributions! Well now I feel like I need to invent some nice small device based on ARM Cortex-M0 CPU ๐Ÿ™‚

Each big failure makes me more calm. Strange.

If you want to install additional Python [1] modules inside your Blender [2] environment, you can install PIP using this recommended script [3], then use PIP to install all modules that you want. Note Blender’s Python Virtualenv location is /path_to_blender/blender_version/python/bin/python and you need to use this particular interpreter to launch the script.

Python 3.6.0 NumPy and SciPy from MacPorts crash on import bug [1].

Google have implemented my idea to make Google Books TTS work like an audio player – it can now work in background and being controlled with bluetooth headset – so I can play, pause and rewind paragraphs of the book read by speech synthesizer just as it was music. This is soo fantastic!!

I have been proposing this solution to Amazon to implement in Kindle for Android, but for years they did not listen. I have switched to Kindle application after Amazon bricked my Kindle3 3G reader with a software update (and all other devices worldwide). Now I just wait until Google Books allow to import my Kindle library, and I will never go back to Kindle. Greedy loses twice.

I have recently started the OrangeADE project [1], that is Orange Autonomous Device Evaluation, an online platform to evaluate security level of network equipment and verify against known vulnerabilities. OrangeADE is released as Open-Source under the “new” 3-Clause BSD license. Enjoy the work in progress! ๐Ÿ™‚

Use advanced features of your Synaptics Trackpad on a laptop running FreeBSD [1] with:

  • set in /boot/loader.conf:
    hw.psm.synaptics_support="1"
  • set in /etc/rc.conf:
    moused_enable="YES"
  • set in /etc/X11/xorg.conf:
    Section "InputDevice"
        Identifier      "Mouse0"
        Driver          "mouse"
        Option          "Protocol"      "auto"
        Option          "Device"        "/dev/sysmouse"
        Option          "ZAxisMapping"  "4 5 6 7"
    EndSection

If you want to have “MacBook” like two-finger scrolling along with other parameters you can set in /etc/sysctl.conf:
