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! ๐

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:
hw.psm.synaptics.min_pressure=16 hw.psm.synaptics.max_pressure=220 hw.psm.synaptics.max_width=10 hw.psm.synaptics.vscroll_hor_area=1300 hw.psm.synaptics.vscroll_ver_area=-600 hw.psm.synaptics.vscroll_min_delta=50 hw.psm.synaptics.vscroll_div_min=100 hw.psm.synaptics.vscroll_div_max=150 hw.psm.synaptics.weight_current=3 hw.psm.synaptics.weight_previous=6 hw.psm.synaptics.weight_previous_na=20 hw.psm.synaptics.weight_len_squared=2000 hw.psm.synaptics.div_min=9 hw.psm.synaptics.div_max=17 hw.psm.synaptics.div_max_na=30 hw.psm.synaptics.div_len=100 hw.psm.synaptics.margin_top=200 hw.psm.synaptics.margin_right=200 hw.psm.synaptics.margin_bottom=200 hw.psm.synaptics.margin_left=200 hw.psm.synaptics.window_min=4 hw.psm.synaptics.window_max=10 hw.psm.synaptics.multiplicator=10000

If you want to use NTFS volumes on FreeBSD [1], you need to use FUSE infrastructure andNTFS-3G [2] port. Syntax of fstab is a bit differen in this case:
/dev/ntfs_partition /mnt/ntfs_mounpoint fuse rw,locale=pl_PL.UTF8,mountprog=/usr/local/bin/ntfs-3g 0 0
Also remember to put fuse_load=”YES” in /boot/loader.conf and install the sysutils/fusefs-ntfs port. Do not use hibernated volumes.

If you happen to get a nice laptop with a powerful graphics card, such as polish HYPERBOOK SL502VR [1], it is highly probable that you will use UEFI boot mode. In that case you need to use SCFB [2] driver instead of VESA. Use the xf86-video-scfb package to get Xorg running.
Hybrid Graphics at first used MUX device that did a LCD connect to a selected video card on boot. Nowadays both cards use common Video Framebuffer [3] to draw over a screen. The simple video card (Intel in my case) is always active, while the more powerful and power consuming video card is started on-demand (nVidia in my case). This however requires a dedicated DMA BUF implementation, which is not yet available on FreeBSD, so none of the cards can see any monitor connected, resulting in “No Screens Found Error” from Xorg.
I have already reported a bug/feature request to nVidia. Also developers of FreeBSD are working on the Hybrid Graphics implementation.

Google Chromecast is a device that allows you to stream audio-video content over WiFi network from Application to a HDMI enabled display. This works really nice when you want to watch Netflix or show some movies from your mobile device on large screen TV/Projector.
Recently, Google released a new line of Chromecast devices that support audio only and higher resolution displays, renaming Chromecast to Google Home. This rebrand also replaced mobile application for devices management. New application forces user to have working internet connection, use localization, and sign with google account in order to work. There is no way to roll back to old application. Not really cool.
I have found and reported one nasty bug in this new Google Home application (version 1.19.29), that prevents you from discovering and setting up old Chromecast devices after Factory Defaults Reset or WiFi password change (so it can connect to your WiFi again). I only have old device so I am not sure how this affects new devices. You will not be able to discover your Chromecast device over WiFi when Localization Services are disabled and according permission was not granted!! In order to connect to your Chromecast:
- Reinstall or clear application data/cache.
- In startup configuration wizard you must grant access to localization services. If you do not enable localization and allow it to work granting permissions, you will not find your Chromecast later on.
- Search now for a Chromecast device still in setup wizard, you will find it, only if you did previous step correctly.
- Note that when you find a device that way, you can skip sign in with google account.
- If you do not grant localization permissions you will not be able to detect your chromecast device anymore.
I hope this has nothing to do with killing old line of devices with a software update. I also hope Google will fix this issue in next releases and they really don’t force users to give up so many personal information (why do they need GPS/Bluetooth running for a simple WiFi connection otherwise)..
