2/26    I just ripped some stuff off of a supposedly copy protected VCD
        from China or Hong Kong (I didn't care about the content, but
        I was curious about the protection) using Alcohol and DVDGear.
        I could not see the mpeg streams from
        either the VCD or the ripped image from my PC unless I did that.
        First, what is DVDGear reading to get the mpeg stream out? Are
        the physical tracks the actual stream with no filesystem?
        Second, the ripped mpegs correspond one to each track, there are
        a total of 8 tracks. I can play the first track with any software
        player like Windows Media Player. However, I cannot play the other
        tracks. The only way to view the other tracks is through a program
        called Nero Media Player. Is there missing header information
        on the subsequent tracks which chokes all the other players and
        Nero Media Player just ignores this? How would I fix this?
        I assume that this method of encoding a VCD is to prevent casual
        people from being able to play the VCD on their computers and
        be able to just rip the disk by doing a simple file copy.
        \_ The .dat files on a VCD are basically just MPEG1 streams.  Just
           copy them.

3/21    Browser Plug-In you must get: Ghostery. It gets rid of a bunch of
        ad trackers on a web site, resulting in really fast load times.
        For example, a typical media site will require 10-15 trackers
        (you know, those URLs that track your activities so they can
        target you better). Ghostery kills them.
        \_ This has been working well for me, and breaks fewer things

8/19    Anyone have a good MLC vs. SLC writeup that is less than a year
        old? I am investigating making a big SSD order. -ausman
        \_ how much performance gain are you expecting from using SSD?
           Let's say your 7200RPM yields 70 MB/sec (sustained) read and
           your new SSD yields 160 MB/sec read, and that your application
           is mostly streaming media (so the platter is continuous read,

        My question is how do stories like this find its way to news media?  Do
        people just go "hey something very interesting happens in our lives.
        Let's call up a news agency or two to tell the world about it."?

1/4     I want to test how my servers behave during a disk failure and
        a RAID reconstruction so I want to simulate a hardware failure.
        How can I do this in Linux without having to physically pull
        a drive? These disks are behind a RAID card and run Linux. -ausman
        \_ According to the Linux RAID wiki, you might be able to use mdadm
           to do this with something like the following:

9/13    Thanks to Jordan, our disk server is no longer virtualized. Our long

2/14    You sure soda isn't running windows in disguise?  It would explain the
        uptimes.

        \_ Nobody cares about uptime anymore brother, that's what web2.0 has
           taught us.  Everything is "stateless".

7/22    Playing with dd if=/dev/random of=/dev/<disk> on linux and bsd:
        2 questions, on linux when <disk>==hda it always gives me this off
        by one report i.e. Records out == records in-1 and says there is an
        error. Has anyone else seen this?  Second, when trying to repeat this
        on bsd, <disk>==rwd0 now, to my surprise, using the install disk and

2/5     I like Adobe Flash. When written correctly, it scales along
        with your browser size. It looks consistent on every single
        browser. It is predictable. On the other hand, I'm not a big
        fan of CSS/HTML, which for the most part, look wildly different
        between browsers, and don't even work consistently or
        correctly at times. So why do so many people (like Steve Jobs)

8/3     VMWare + Windows XP + Validation question. I need to test stuff with
        Service Pack 3 installed. I have a valid key that I own (yeah yeah I
        actually *bought* a copy, please don't flame me for supporting evil
        M$). Is it possible to register the key once, and then duplicate it
        for testing purposes?  Will Windows or Microsoft detect copies and
        disable the rest the copies?
