Hauppauge Broadway: OTA ATSC streaming for iOS devices….

datePosted on 23:27, January 16th, 2011 by Many Ayromlou

Yep, just like the title says, hauppauge has announced the Broadway, a new “set-top” aimed at iPhone, iPad and iPod touch users. The hardware streams live OTA HDTV to an Apple handheld after first compressing the video using H.264. The resulting media can be delivered locally over Wi-Fi, or to a remote place using any Internet connection. Over-The-Air ATSC signals can be captured using a built-in ATSC tuner, while cable is supported through clear QAM. Pricing is a bit steep at $199 and the box is scheduled for February release.

Optimizing Snow Leopard for SSD drives….

datePosted on 22:13, January 16th, 2011 by Many Ayromlou

I just installed a new 128GB SSD drive in my older C2D 17″ macbook Pro and let me tell you….WOW….This thing is on fire. The system is extremely responsive and apps literally jump onto the screen. The machine now boots up to full desktop in roughly 17 seconds. Now that’s nice. I did do a bunch of changes to the way Snow Leopard is setup to optimize a couple of things that are normally tuned for HDD’s.

  • Turn off Sudden Motion Sensor (SMS): If you are replacing your primary (and only) HDD internal drive with a SSD, you can get a bit of a performance boost by turning off the Sudden Motion Sensor technology that comes with your laptop. Remember your SSD doesn’t use read/write head on rigid platters so there is no reason to keep this feature turned on. You can safely turn it off by issuing the command below in Terminal, type in administrator password when asked.
    sudo pmset -a sms 0
  • Turn off hibernation and delete sleepimage file: Using SSD, you can achieve under 20 seconds boot-up time. Why bother using Hibernation and waste too much space on your SSD. To do so, issue the commands below in Terminal, enter administrator password when asked.
    sudo pmset -a hibernatemode 0
    sudo rm /var/vm/sleepimage
  • Reduce disk I/O by mouting partition with noatime: Stop OSX from updating “last access time” or atime everytime a file is touched on your filesystem. This is IO expensive and unnecessary. In a terminal window create a file called com.nullvision.noatime.plist under /Library/LaunchDaemons folder and stick the following lines in the file. Save the file (you need to sudo when you edit the file) and reboot your machine.
    <?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN"
            "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
    <plist version="1.0">
        <dict>
            <key>Label</key>
            <string>com.nullvision.noatime</string>
            <key>ProgramArguments</key>
            <array>            
    		<string>mount</string>
                	<string>-vuwo</string>
                	<string>noatime</string>
                	<string>/</string>
            </array>
            <key>RunAtLoad</key>
            <true/>
        </dict>
    </plist>

    Once the machine has rebooted you can check to make sure your root partition is mounted with noatime by issuing the following command

    mount | grep "/"

    and look for something similar to this in the output

    /dev/disk0s3 on / (hfs, local, journaled, noatime)

This should do it. Have fun with your new SSD drive.

Galaxy sub-brand KFA2 has just announced their new KFA2 GTX460 WHDI nvidia based wireless graphics card. The KFA2 GTX 460 WHDI uses a wireless link (WHDI) to send the display output from your PC to your screen. You just need to attach the bundled receiver to the back of your monitor/screen and you’re done.

The card’s name comes from Amimon’s wireless technologyWHDI stands for Wireless Home Digital Interface. WHDI 1.0 provides a high-quality, uncompressed wireless link which supports data rates of up to 3Gbit/s (allowing 1080p) in a 40 MHz channel, and data rates of up to 1.5Gbit/s (allowing 1080i and 720p) in a single 20 MHz channel of the 5 GHz unlicensed band, conforming to FCC regulations and worldwide 5 GHz spectrum regulations. Range is beyond 100 feet (30 m), through walls, and latency is less than one millisecond. The WHDI standard supports HDCP 2.0, so it can route protected content (Blu-ray films, for example) without a problem.

Aside from having five aerials rather than display outputs, the card is a typical GeForce GTX 460 1GB affair. It supports Nvidia’s PhysX and CUDA technologies, and it’s DirectX 11-compatible. NICE, I want one :-).
