    As to "why" - At one point he popped a wheelie and was doing 129 MPH. He deserved to get pulled over.

    HOWEVER, the method of pulling him over was "Car (VW?) with darkly tinted windows cuts you off and driver comes out brandishing a gun." - Effectively indistinguishable from a road rager.

    I did not see any signs of the police attempting to do a standard pull-over manuever (e.g. turning their lights on) - I did not see ONE sign of any active police vehicle lights.

    Oh yeah, I don't know about Maryland tint laws, but in New York State that cop's vehicle's tinted windows would have been illegal. (In NYS, standard passenger vehicles and station wagons are not permitted to have tint on any side windows. Some vehicles can get around this by classifying as "light truck" - my Subaru Outback carries a SUBN classification due to fold-down rear seats and a rear cargo area, allowing Subaru to put factory tint on the rear side windows, but I don't think that little VW hatch could be classified as such.) Many of the NYS tint laws are actually intended to protect cops from situations just like this motorcyclist was in ("surprises" from heavily armed vehicle passengers or driver).

    I remember one particular set of instructional videos (how to download Ibycus Topo) consisted of 3 10-minute videos.

    If you were moderately computer-savvy and had familiarity with BitTorrent, you only needed 30 seconds that started 8:30 in the first video (where to find the .torrent file, which the person who released Ibycus Topo didn't bother to link directly to.)

    What was funny was the only source for the .torrent file was ThePirateBay, despite the fact that this particular dataset was 100% free/legit as it was derived from government data sources that had VERY permissive licenses. (It was distributed by BT to save the author's bandwidth, and I guess TPB was the first torrent hosting site/tracker he thought of.)

    You mean AAC?

    Because AC3 (Dolby Digital) can definately not be put into an MP4 container. This is probably the #1 reason the "scene" uses MKV. (Typical MKV "scene" releases are 720p MPEG-4 AVC aka H.264 with the original source AC3 audio, since unless the source is DTS, the original AC3 is basically the only way to provide surround sound to 90% of home theater setups out there.)

  6. Re:Handbrake on Encoding Video For Mobile Devices? · · Score: 1

    With modern CPUs, 10 times faster isn't much of a difference, especially if your source content is high resolution (decoding takes the bulk of the time, since for transcoding you usually can't have hardware acceleration).

    Also, in general, my experience is that most MPEG-4 ASP encoders were developed and perfected back in the days of single-core CPUs, and people haven't done much work into multithreading them. H.264 encoders, on the other hand, have been the focus of a LOT of multithreading optimization. The end result is that in my experience, the difference in speed between H.264 and MPEG-4 ASP (DivX/XviD) is really only 2-3x once you take into account the improved multithreading of current H.264 codecs and the fixed amount of CPU needed for decoding the source format.

    Since you can kick off a bunch of queued jobs and then go to bed, such a difference in speed basically becomes irrelevant compared to the time you'll save in terms of dealing with target platform incompatibilities. If you're targeting ANY mobile phone, H.264+AAC in an MP4 container is the way to go.

  7. Re:Handbrake on Encoding Video For Mobile Devices? · · Score: 1

    The above SHOULD work if it is an MKV with H.264 video and AAC video. It works for me.

    However, a lot of "scene" MKVs are H.264 video and AC-3 (Dolby Digital) audio. AC-3 audio can't be put into an MP4 container (which is one reason MKV is used). AC-3 or DTS is the required format for 90%+ of surround sound systems out there, which is why that format is used for the audio instead of AAC.

    To play such MKVs on a PS3, you need tsMuxer to remultiplex the H.264 video and the AC-3 audio into an MPEG transport stream (.m2ts)

    Also, MKV supports chapters and subtitles, I'm fairly certain the MP4 container doesn't. The MP4 container is VERY limited in capability.

    However, if targeting mobile devices (no need for surround sound), the MP4 container is the way to go, especially since many phones have some degree of AVC hardware acceleration these days.

  8. Re:VHF/UHF are mainly line of sight on Amateur Radio In the Backcountry? · · Score: 1

    There are exceptions to the line of sight rule for VHF/UHF, such as knife edge diffraction, reflections (e.g. your signal might bounce off of a valley wall and reach a repeater just out of LOS) and tropospheric ducting (likely not to see that in mountains, it's more of an over-water thing usually.)

    However you can't rely on these to get you more than a little bit of extra distance unless you get lucky.

  9. Re:Mobile crossband repeater on Amateur Radio In the Backcountry? · · Score: 1

    "due to FCC regulation of wattage allowed for handheld transcievers, antenna size, and even vehicle groundplane"

    There is no such thing for amateur radio transcievers.

    However, there's a practical limit of around 5 watts for handhelds dictated primarily by thermal management and battery power available in that form factor. Mobile rigs have a nice big car battery backed by an alternator to run off of. (Running directly off of a car battery for extended periods is not advised - starter batteries do not like being deep cycled.)

    A useful thing when traveling is to build a J-pole antenna from twinlead. J-poles have pretty good gain, and are normally NOT a compact antenna, however if constructed from twinlead, you can roll it up and just hang the end off of something when you want to use it. Plenty of variants on this available from Google, including http://www.qsl.net/wb3gck/jpole.htm and http://larc.hamgate.net/pocketJpole.htm

  10. Re:depends on where the repeater is on Amateur Radio In the Backcountry? · · Score: 3, Informative

    A little more technical detail:

    Most small/compact (handheld) amateur radios are UHF/VHF units. (Usually called HTs, for Handheld Transceivers) The two most popular ham bands are the 2 meter (144-148 MHz) and 70 cm (approx. 440 MHz, I'm a bit rusty and haven't touched my radio in a few years.)

    VHF/UHF communications is line of sight based, so unless you're within LOS of a repeater, you probably won't be able to do much, unless you have friends nearby with similar units. You can operate VHF/UHF HTs in a unit-to-unit (Simplex) mode, but most people use them to talk via repeaters. Repeaters listen on one frequency and transmit on another, usually with an offset of 600 kHz in the 2 meter band. Even if you are in coverage of a repeater, it's not always guaranteed someone will be listening.

    APRS (Automatic Packet Reporting System) can report your position with periodic position broadcasts. This could let friends track your movements whenever you're in coverage of an APRS gateway or digipeater, for example at http://aprs.fi/

    There are also portable solutions for HF (global) communications (frequency 30 MHz), but the most portable solutions (suitable for a backpacker) will only do Morse code and not voice.

    Getting a license is pretty easy and cheap (no Morse code required for the Technician license that allows VHF/UHF operation, and the FCC may even be allowing operation on the HF bands without a Morse test now - I'm not sure if they've updated their rules based on the ITU rule changes a few years ago), so I would recommend starting the process of studying and finding an exam session now.

    Although this leads to one of the few truly legitimate reasons I can think of for it to be illegal while tobacco and alcohol (far worse drugs in general, for differing reasons) are legal. I'm not sure if there is an easy scientific method to determine "under the influence" or "not under the influence" without behavioral tests that are a lot easier to challenge in court than a breathalyzer. Pot is known to stay in your system for quite a while after its effects are gone.

    I loved playing through most of the game using the stealth mode... It's a bit slower but takes more finesse.

    However, the multiplayer design of Crysis was absolute shit. Anyone should've picked up from the DX9-clients-can't-mix-with-DX10-clients that Crytek violated one of the first rules of multiplayer game architecture - DO NOT TRUST THE CLIENT. In Crysis' case, apparently they offloaded world physics calculations to the client, and also trusted the client WAY too much.

    For example, if a client said, "my 9mm pistol does 9999 damage", the server would say, "OK, 9999 damage to your target. Oh look, it's instadead."

    Similarly, if a game client said, "My vehicle is immune to all forms of fire.", the server would happily say, "You got hit with a missile. Oh, you're immune to explosive damage - no damage at all!"

    I played multiplayer for two weeks, the second of which was playing with the INI files figuring out what degree of cheating would not get noticed. (Thanks to the blatant instakillpistol cheaters, there was a LOT of potential for nonobvious cheating, such as the 400HP Toyota truck with a tweaked suspension.) After that I uninstalled the game and haven't played since. Cheating was, of course, unexciting other than the technical challenges of modding the game. Playing legit was pointless because of the ease of cheating.
