Forum poster pet peeve - Subject line usage

2010-09-15T09:19:00.000-05:00

"I'm having problems with..."
"Can your application..."
"Can you....."
"Is there a way to... drag out your message processing and drive you nuts trying to figure out what the hell people are saying without saying anything. It's a subject line, WTF is the subject!"

And the same thing goes for email, twitter, facebook, etc.

Side note: I'm inversely amused at posts like this:
"I'm baaaaaaack", followed by "-no responses"

Moving from Firefox to Chrome - keywords and search engines

2010-05-11T13:43:00.000-05:00

Searching from the address bar is one of my favorite features of any browser. For example, if I want to search Wikipedia for Bill Gates, I enter the following string into the address bar: w Bill Gates

Or if I'm searching for a movie: m Star Wars

These shortcuts can work with multiple search engines and multiple browsers. You can add search engines to Firefox by looking through their addon library. You can add them to Chrome manually. Here's my top four Chrome search engines, listed by keyword, search engine name, and search engine URL string:

Script for bulk encoding videos to H.264 with Handbrake

2010-02-15T10:26:00.004-06:00

I'm writing this because I needed a simple way to drop a batch file onto a computer, let it run for a few days, and when I come back all my files have been magically converted to H.264. So before we begin, I'm going to assume you have some knowledge of computers, scripts, and video encoding (Windows, Mac, or Linux). Be careful with the word wraps on this post, the command lines being executed are quite long!

Why H.264?
Much like MPEG2 for DVD video or MP3 for audio, H.264 is a flexible video standard for all sorts of media, such as Blu-ray Discs, web streaming, and portable video devices (iPod Touch or iPhone). Here's a little background information for H.264 and x264:
H.264 is a form of video compression - http://en.wikipedia.org/wiki/H264
x264 is a method(software) for encoding video into H.264 - http://en.wikipedia.org/wiki/X264

One of the things I like so much about H.264 is that it's very flexible. You can encode videos into very high quality HD videos, or something low resolution for use with a phone. The x264 software allows us to make these these adjustments very easily. We'll be using the command line version of Handbrake to do all our encoding. http://handbrake.fr It's free, available for Windows, Mac, and Linux. I'll assume you have the latest version installed at this location: "C:\Program Files (x86)\Handbrake\Handbrake.exe"

Bulk encoding
There's more than a few ways to do this. If you're on a Windows PC probably the simplest way is to use a batch file. If you're like most people, your videos are stored in a particular location. For example, you may have a directory structure like this:

c:\videos
c:\videos\video1\video1.mpeg
c:\videos\video2\video2.avi
c:\videos\video3\video3.xvid

We'll use a batch file to start at the base directory (c:\videos) and work ourselves down through all the subdirectories and encode the video files into H.264. Here's an example batch file that can traverse subdirectories and do something along the way, convert.bat:

@for /r %%F in (*.filetype) do (
 some command here
 some command here
 some command here)

Encoding methods
Handbrake is quite flexible when it comes to importing various file types. I've been able to import DivX, XviD, wmv, etc. One of the most important components of video encoding is the quality. With Handbrake you can handle this three ways:
- setting an average bitrate (1500 kbps for example)
- setting a target file size (Handbrake will adjust the bit rate to fit the requested size)
- setting a constant quality
For our encoding process we'll be using the constant quality method. The first two methods work well if all your videos are from the same source, the same resolution, and using the same codec, but if you have a mixed bag of videos then constant quality is easier to work with.

What quality level should we use?
I'd suggest running a few tests first. Find a video file (the shorter the better, such as a movie trailer), and lets encode it with various levels of quality. In Handbrake, 100% quality is an extreme amount and you'll probably never use something this high. So we'll start with 40%, 50%, 60%, and 70%. After the encoding process is complete, take a look at the file sizes and the level of quality. It may be that you'll need to adjust the level to 65%, or 55%.

I'm encoding my videos for playback on Apple TV, iPhone and iPod Touch. The iPhone\Touch can playback video with a resolution up to 640 x 480 (even though the displayed video is only 480 x 320). You can adjust these settings as well. For example you may want to encode video to 720p or 1080p, to do so just read up on Handbrake's command line switches for -X -Y -w -l, more info here: http://trac.handbrake.fr/wiki/CLIGuide I'm also limiting the audio to 64kbps. You can bump this up as well using the -B switch, something like -B 128.

OK, so you've found a video that you'd like to test. A short video, correct? Place the video in a directory all by itself. Create a new batch with this code in the same directory. Start up a command line windows, navigate to the directory, and run the batch file. Depending on your hardware, this encoding process may take a few minutes, or a few hours if you're using a long video (I told you to use a short video).

@for /r %%F in (*.avi,*.mov,*.wmv,*.mpg,*.mpeg,*.divx) do (
"C:\Program Files (x86)\HandBrake\HandBrakeCLI.exe" -i "%%F" -o "%%~pnF-x40.mp4" -f mp4 -2 -I -O -X 640 -Y 480 -e x264 -q .40 -a 1 -E faac -6 auto -R Auto -B 64 -D 0.0 -m -x level=30:bframes=0:cabac=0:ref=1:vbv-maxrate=400:vbv-bufsize=2000:analyse=all:me=umh:no-fast-pskip=1:psy-rd=0,0:subq=6:8x8dct=0:trellis=0:weightb=0:mixed-refs=0 -v 1
"C:\Program Files (x86)\HandBrake\HandBrakeCLI.exe" -i "%%F" -o "%%~pnF-x50.mp4" -f mp4 -2 -I -O -X 640 -Y 480 -e x264 -q .50 -a 1 -E faac -6 auto -R Auto -B 64 -D 0.0 -m -x level=30:bframes=0:cabac=0:ref=1:vbv-maxrate=500:vbv-bufsize=2000:analyse=all:me=umh:no-fast-pskip=1:psy-rd=0,0:subq=6:8x8dct=0:trellis=0:weightb=0:mixed-refs=0 -v 1
"C:\Program Files (x86)\HandBrake\HandBrakeCLI.exe" -i "%%F" -o "%%~pnF-x60.mp4" -f mp4 -2 -I -O -X 640 -Y 480 -e x264 -q .60 -a 1 -E faac -6 auto -R Auto -B 64 -D 0.0 -m -x level=30:bframes=0:cabac=0:ref=1:vbv-maxrate=700:vbv-bufsize=2000:analyse=all:me=umh:no-fast-pskip=1:psy-rd=0,0:subq=6:8x8dct=0:trellis=0:weightb=0:mixed-refs=0 -v 1
"C:\Program Files (x86)\HandBrake\HandBrakeCLI.exe" -i "%%F" -o "%%~pnF-x70.mp4" -f mp4 -2 -I -O -X 640 -Y 480 -e x264 -q .70 -a 1 -E faac -6 auto -R Auto -B 64 -D 0.0 -m -x level=30:bframes=0:cabac=0:ref=1:vbv-maxrate=900:vbv-bufsize=2000:analyse=all:me=umh:no-fast-pskip=1:psy-rd=0,0:subq=6:8x8dct=0:trellis=0:weightb=0:mixed-refs=0 -v 1)

After this batch file runs you should have 4 new videos, each at a different levels of quality. If you'd like to tweak your quality level, you can adjust the -q value up or down, such as -q .55 or -q .65 and you can also adjust the maximum bitrate with the vbv-maxrate=somevalue_kbps.

For my videos, I'm going with these settings:

-2 [two-pass encode]
-T [make the first pass go turbo!]
-O [optimize for web streaming, YAAA]
-I [for 5.5G ipods]
-X 640 [maximum width]
-Y 480 [maximum height]
-q .60 [not bad, not great, good file size]
-B 64 [64kbps is enough for me]

In the batch file, we'll be looking to convert any avi file, divx file, wmv, etc. Place this file in your base video directory (such as c:\videos) and let it run (it may take a while to complete). It will crawl through all your subdirectories looking for video files to convert. We'll also dump our progress to a log file so you can see what video is currently being encoded. And when you put all this together with the other settings, here's what it looks like... aka, the TL;DR section:

@for /r %%F in (*.avi,*.mov,*.wmv,*.mpg,*.mpeg,*.divx) do (
@echo "- starting %%F"  >> convert.log
"C:\Program Files (x86)\HandBrake\HandBrakeCLI.exe" -i "%%F" -o "%%~pnF-x60.mp4" -f mp4 -2 -T -I -O -X 640 -Y 480 -e x264 -q .60 -a 1 -E faac -6 auto -R Auto -B 64 -D 0.0 -m -x level=30:bframes=0:cabac=0:ref=1:vbv-maxrate=700:vbv-bufsize=2000:analyse=all:me=umh:no-fast-pskip=1:psy-rd=0,0:subq=6:8x8dct=0:trellis=0:weightb=0:mixed-refs=0 -v 1
@echo "- completed %%~pnF-x60.mp4"  >> convert.log)

If you want date & time in the log file:

@for /r %%F in (*.avi,*.mov,*.wmv,*.mpg,*.mpeg,*.divx) do (
@echo - starting %%F >> convert.log
date /t >> convert.log
time /t >> convert.log
"C:\Program Files (x86)\HandBrake\HandBrakeCLI.exe" -i "%%F" -o "%%~pnF-x60.mp4" -f mp4 -2 -T -I -O -X 640 -Y 480 -e x264 -q .60 -a 1 -E faac -6 auto -R Auto -B 64 -D 0.0 -m -x level=30:bframes=0:cabac=0:ref=1:vbv-maxrate=700:vbv-bufsize=2000:analyse=all:me=umh:no-fast-pskip=1:psy-rd=0,0:subq=6:8x8dct=0:trellis=0:weightb=0:mixed-refs=0 -v 1
@echo - completed %%~pnF-x60.mp4 >> convert.log
date /t >> convert.log
time /t >> convert.log)

Other utilities
MediaInfo is an informative little app. And with it's context menu it's very handy. It's good at finding video codec information, audio codec, resolution, bit rate, etc - http://mediainfo.sourceforge.net/en

Better performance with Compiz Fusion in a VirtualBox VM on Windows 7

2010-01-11T11:10:00.004-06:00

First some background.... my previous entries about VMware and VirtualBox:

Compiz Fusion and VMware Workstation 7 not playing nice:
http://orsontyrell.blogspot.com/2009/11/compiz-fusion-and-vmware-workstation-7.html

Compiz Fusion and Virtual Box 3.10 playing together:
http://orsontyrell.blogspot.com/2009/11/compiz-fusion-and-virtual-box-310.html

Today I'm seeing some great performance improvements with the latest version of VirtualBox, version 3.1.2. Specifically I'm now satisfied with the performance of Compiz Fusion running in a VM on Windows 7. Previous I'd see delays in the menuing system or delays when typing in a terminal window, but now the windowing performance is fine.

After upgrading to VirtualBox 3.1.2, I upgraded the VirtualBox Guest Additions on an existing VM, and I also tested a new VM. In both instances (an Ubuntu VM and a Linux Mint VM) I saw the same performance improvements.

Halo Reach: this is not the media you're looking for, move along.

2010-01-07T10:51:00.001-06:00

The CES 2010 Keynote Address is available online. Great, except it's not. At around the 1 hour mark, Microsoft's President of Entertainment and Devices Division Robbie Bach mentions the latest episode in the Halo saga. Instead of showing the video presented at CES, the viewer is greated with the screenshot below:

Why not show the video?
or Why not just cut the video out all together?
Why leave it on the screen to linger for over two minutes, all the while playing crappy elevator music?

Oh and sure, when the video feed returns, we're greeted with the audiance's applause of what they just saw... thanks Bungie.

[UPDATE]
uggh... and they do it again with Microsoft's own Gameroom Arcade...

MP3 to M4B: free, quick, and easy audiobook coversion for your iPhone

2010-01-04T20:46:00.004-06:00

Quick?
Maybe, maybe not. Depends on your hardware.

Why M4B?
MP3 is nice for songs, but if you have a long audio book in MP3 form, it may be 10, 20, 30+ individual MP3 files. M4B lumps them all in one. M4A is similar to M4B, but it doesn't offer bookmarking(remembering playback location) which is a necessity when listening to a long audiobook. Sure, in some instances an app will remember the playback location of both MP3 and M4A, but as the file size increase so does the chance loosing your location. http://en.wikipedia.org/wiki/M4b

So why not just throw everything in iTunes and use a playlist?
In my experience, the iPod app for the iPhone sucks. Plan and simple. Everytime I charge my iPhone via the computer's USB port, the iPhone looses it current playback location. I've run into similar instances when syncinging. So what the solution? I've found an audiobook player app with some good features, and most importantly it doesn't loose it's playback location. The app even supports background playback (the only non-Apple app I've come accross that does this). The app is called Bookmark http://bookmarkapp.com/ , Bookmark Blog http://bookmarkapp.wordpress.com/

And now let's start with some apps that I've tried, but for one reason or another haven't had much success:

Audiobook Maker version 0.1b for Mac OSX - http://audiobookmaker.sourceforge.net/ - A free MP3 to AAC app. For me, this app is hit and miss. Sometimes it works, sometimes it crashes, and sometimes I just get the spinning beachball. The good news is it's open source if anyone wants to pick it up, unfortunately the app was last updated Dec 03, 2005 (http://sourceforge.net/projects/audiobookmaker/files/). Maybe it's incompatibilities with Snow Leopard, I don't know.
MP3 to iPod Audio Book Converter version 0.18 for Windows - http://freeipodsoftware.com/ - Another free all-in-one type app. And again, it's hit and miss with conversions. I tend to have better success when running it on XP, unfortunately most of my PCs have moved to Windows 7. When running under Win 7 I tend to run into a Java error at the start of the conversion process.

A successful 3-step process:

MP3 files to M4A files - using Format Factory version 2.20 - http://www.formatoz.com/ - This free app converts all kinds kinds of media. If you have a large number of files to convert it has a great queuing system. Just drop them in the queue and let it crank away. Out comes the M4A files.
M4A files to a single chaptered M4B - using Chapter and Verse version 1.3.3.5 - http://lodensoftware.com/chapter-and-verse/ - Another free app. Creating the M4B is rather simple, just add the M4A files, make any necessary meta data changes (Author, Title, Album Art, etc), then click the Build Audiobook button. Individual files are converted to chapter breaks in the single M4B file, but with the Bookmark app this isn't really neccessary.
Drop the M4B into iTunes and BAM! your done. If you don't want to use iTunes, you can use CopyTrans Manager http://www.copytrans.net/

Flash 10.1 beta 2, Mac and Linux now available

2009-12-25T09:32:00.000-06:00

Adobe has released an update to their beta Flash (GPU accelerated Flash). They're up to Flash 10.1 beta 2. Binaries are available for Windows, Mac, and Linux:
http://labs.adobe.com/technologies/flashplayer10/

With the latest nvidia drivers (on Windows 7) I saw quite a performance improvement with Flash 10.1 beta 1. http://orsontyrell.blogspot.com/2009/11/flash-101-gpu-acceleration-non.html
Now that binaries are available for the Mac (Flash 10.1 beta 2) I'm able to do some similar tests. I ran these tests on a MBPro that has an integrated GeForce 8600M GT.

Flash 10.0.42.34

Flash 10.1 beta 2, 10.1.51.66

Unfortunately I'm not seeing any gains in performance. Playback of the 2012 HD trailer (http://www.youtube.com/watch?v=Hz86TsGx3fc) runs the CPU to around 45% with both Flash 10 and Flash 10.1 beta 2.

So what's the problem? I suspect it's the nvidia drivers that are released by Apple. I can't remember the last time I've seen a graphics driver update for OSX. On the Windows side it seems there's an update every other month. In my previous test of Windows Flash 10.1 beta, the drivers are what made the difference. Upgrading from Flash 10 to Flash 10.1 didn't show any improvements, but after I upgraded the graphics drivers to the latest WHQL, I saw a huge improvement. I'm hoping for an update to the OSX graphic drivers, but I'm not holding my breath. In the meantime, this just gives us another reason to use bootcamp.

TWiT video is available on the web, h264 HQ and LQ

2009-12-12T16:49:00.002-06:00

On Demand TWiT has been around for a while with ODTV.me, but it's a low quality flash capture from fans. Today we can get HQ and LQ video from several shows, produced from the TWiT crew. Once an RSS feed is available I'm sure BoxeeHQ's TWiT plugin will get an update. It looks like the video is h264 854x480 and 640x368. I'm seeing video on Windows Weekly, TWiT, and Mac Break Weekly.

Windows Weekly:

Google's search results show twitter feeds

2009-12-08T08:23:00.001-06:00

Perhaps I'm late to the game but I just noticed this....
If you do a Google search for a twitter user and the word "twitter" you'll see a new display section of the user's recent tweets. As time goes by the section will be populated with new posts and you'll get a scroll bar to move up and down the posts. If you click the "Latest results" link you'll see a list of the last dozen or posts. As new posts comes in the list is updated in real time. After the twitter section you'll see the normal Google results.

Boxee Beta details, now with DXVA (DirectX Video Acceleration)

2009-12-07T20:32:00.000-06:00

A recent blog post from Boxee gives details about the new public beta release due Jan 7th (they're still in alpha). The most important detail in the announcement... support for DXVA. What's so cool about that? If your processor has problems displaying High Def video (720p, 1080p) then you may see some performance improvements with the CPU offloading video decoding to the GPU (your graphics card). For example, if you have a blu-ray rip that's encoded 1080p your CPU alone may not be able to handle decoding, especially since Boxee's decoder doesn't take advanage of dual/quad CPUs, neither does VideoLan's VLC media player. Instead of using Boxee/VLC you'd need to use something like ffmpeg's multi-core codec with Media Player Classic. And for those of you with an ION based computer (netbook, HTPC, etc) you should see some benefits as well.

Video from their announcement is here:

DNS benchmark showdown: Google DNS, Open DNS, Comcast, and more. Using Google's new DNS tool

2009-12-05T13:08:00.000-06:00

Google is providing a new DNS benchmarking tool for free. Available in .dmg, .exe, .tgz.
http://code.google.com/p/namebench/

I ran the test a few times against my default ISP settings for DNS (Comcast). Some example results are below. I was hoping for better performance from Google's DNS, but perhaps I'll try again at a later time. In my tests so far, my ISP's DNS usually comes in first or second (second to UU Cache-4). At times Sprint and OnRamp will make it to the top.

Then again speed is not be everything. OpenDNS has tons of cool features. And as a side note, I'm using dd-wrt on a linksys router (default DNS settings) running the tests from a MBpro.

Adding video feed to Boxee, such as YouTube video

2009-12-04T15:26:00.000-06:00

Be on the lookout for a new release of Boxee. It should be any day now.
In the current version, they make it easy for us to add content. The steps are amazingly simple:

Start Boxee
Click 'App Box'
Navigate to the 'My Feeds' tab
Click 'Add New Feed'
Type in the video feed's url. For example if you'd like to add the YouTube video feed for The Computer Action Show, you'd use 'http://feeds.feedburner.com/computeractionshowvideo' without the quotes
Check the Feed Type box for video
Click OK

After that you can navigate to Applications -> Video and you should see the show's icon. Adding audio is almost exactly the same, just select the appropriate Feed Type.

Requirements for a HTPC

2009-12-01T20:57:00.000-06:00

My replacement powersupply, a Shuttle PC55 450W, sounds like a helicopter taking off. It's a least 20db higher than the stock 350W.

It's getting long in the tooth so now I'm thinking about a new HTPC. My must-have features:

quiet, I don't mind a small amount of noise.
1080p playback of h264.
small, shuttle size would be acceptable.
good video graphics, either with ION or a PCI Express slot. I'd like to use the GPU for flash acceleration.

I'm considering something extremely small, something like ASUS's EEE Box 1501, http://www.pcper.com/comments.php?nid=8027

[UPDATE] The pc55 isn't as noisy as I thought. I had a cable rubbing against the fan, ugh.

When UPS 2-day air isn't 2 days... more like slow-ass day air

2009-11-29T11:07:00.000-06:00

I'm home a little early on Wednesday afternoon, ready for a 4 day turkey weekend. I fire up the 'ol HTPC for some boxee\hulu\mkv... and nothing. After a some troubleshooting, it's the powersupply. Unfortunately this is a small form factor PC so it requires a non-standard sized powersupply. I hop on the interwebs, find a replacement, schedule it for 2 day air, and then I sit back and wait, and wait.

I placed my order on the 25th, and deliver is scheduled for the 30th, a monday. Great! I'll get my HTPC up and running right when the full week starts. What the hell!?!? So instead of watching quality shows on the internet (TWiT, fringe, the cleveland show) I stare at the UPS package tracking page all weekend:

and whats up with that stop in Dallas?!?!? it arrived on the 28th at 6am, and it sits there for over a day. Come on people, I need to watch some hak5 and tekzilla. WTF!

Flash 10.1 GPU acceleration (non-scientific) tested. WHQL drivers make a difference.

2009-11-17T21:22:00.000-06:00

MBpro, dual core 2.4 Ghz, Nvidia 8600M GT, bootcamp Win 7

2012 trailer in HD:
http://www.youtube.com/watch?v=Hz86TsGx3fc

[Default bootcamp/Win 7 drivers]

Using Flash 10.0.32.18, bootcamp/Win drivers, CPU usage averaged around 55%:

Using Flash 10.1.51.25 beta, bootcamp/Win drivers, CPU usage averaged around 65%:

[Updated default bootcamp/Win 7 drivers to Nvidia's latest 186.81 WHQL drivers]

Using Flash 10.0.32.18, 186.81 WHQL drivers, CPU usage averaged around 50%:

Using Flash 10.1.51.25 beta, 186.81 WHQL drivers, CPU usage averaged around 35%:

Summary:
Using the default drivers I didn't notice a big difference when upgrading to the Flash beta (55% to 50%) . When I switched drivers to 186.81 I saw a decrease in CPU usage from ~65% to ~35%. wow

[UPDATE] It looks like AnandTech came up with similar numbers, from 450% to 190%. CPU usage dropped by more than half.

GPU accelerated Flash... not so fast Mac, you too Linux.

2009-11-17T19:07:00.000-06:00

The beta is available for Mac, but no hardware acceleration. Windows only for now:
http://labs.adobe.com/technologies/flashplayer10/

From the Hardware requirements section:
http://www.adobe.com/devnet/flashplayer/articles/fplayer10.1_hardware_acceleration.html

Linux and Mac OS X hardware-accelerated decoding is not supported in this version.

Blogging browser, Part 2: Flock

2009-11-11T09:54:00.000-06:00

Firefox + ScribeFire was nice, but I've found something even better, Flock Browser.
Flock Browser - The Social Web Browser

It has support for twitter, blogging, email, instant messaging. An interesting feature is broadcast. It reposts your stuff to more than one site. And since based off Firefox, it's cross plateform! Mac, Linux, Windows.

If you're looking for an online, minimalistic, word processor, here's what you'll need:
Google Docs
Firefox
Stylish Add-on : Stylish :: Add-ons for Firefox

Once installed, you can select a style to use when you're editing a Google doc. Several dark-room type scripts are available for the minimalistic writer. Once you've chosen your style, hit F11 for full screen. I prefer the full black screen with green text:

Here's what i use:

@namespace url(http://www.w3.org/1999/xhtml);

@-moz-document domain("docs.google.com") {

tr#navigation{
    display: none !important;
}

.editor {
    margin: 30px auto !important;
    width: 100% !important;
    max-width: 800px !important;
    background-color: #000 !important;
    color: #00DD00 !important;
    font-size: 100% !important;
    line-height: 100% !important;
}
}

The code is simple enough for most people to understand. Some people prefer a tighter column, different color text, etc.

iPhone is the new Windows: Worms, Viruses, and Trojans

2009-11-09T07:51:00.000-06:00

New article on tuaw.com:Worm rickrolls unsecured jailbroken iPhones via SSH

If you have a jail broken iphone, and you didn't change the default SSH password, you're vulnerable. But let's say you did change your password, are you safe? How long before someone adds a dictionary attack to the worm, and starts searching for weak passwords? That's one of the methods that the Conficker work spread. I'm amazed at how many people have a password of '12345'. Is this Apple's fault? or Microsoft's fault? Who will get the blame for this particular worm: the jail breakers? ikee? Cydia?

And if it's not SSH then it's SMS; Apple patching nasty iPhone SMS vulnerability
And if it's not SMS then it's Safari; iPhone Flaw Lets Hackers Take Over
And if it's not Safari...

So is it as bad as Windows? Not until the iPhone/OSX reaches the mass market... oh wait, has that happened?

On the Windows side if you find an exploit, say RPC vulnerability, how many machines can you hit? The tools are easy to come by, the data you can steal is valuable, and the targets are everywhere.

Compiz Fusion and Virtual Box 3.10 playing together

2009-11-04T15:03:00.002-06:00

Unlike VMware Workstation 7, Virtual Box can enable Compiz Fusion right out the box. I'm impressed. Shouldn't this have been on VMware's list? I think they focused too hard on Windows 7 and Direct X support. I think they're missing the boat on this one... not to mention Virtual Box is free! VirtualBox

After a little more testing, I notice slight delays when working with windows that are semi-transparent or fade in/out of some level of transparency. As with most things in Linux, there's probably a setting to enable/disable window transparencies.

[UPDATE] I've tried increasing the resources, memory and cpu, but I'm still noticing a slight delays in window painting, menu refreshes, etc. With Compiz Fusion turned off, performance is great. Adding additional CPUs to the VM was a bit tricky. When I attempted to start a VM with more that one CPU, I'd get an error, "vt-x is not available". After some googling I found four setting in the BIOS that needed to be configured:
    * Security > Execute Disable (set to On)
   * Performance > Virtualization (set to On)
   * Performance > VT for Direct I/O Access (set to On)
   * Performance > Trusted Execution (set to Off)

I found the information here: http://www.shnake.com/blog/?p=419

Compiz Fusion and VMware Workstation 7 not playing nice

2009-11-04T14:44:00.004-06:00

On a default install of Ubuntu 9.10, with 3D acceleration enabled on VMware, Compiz Fusion is not working. :(
"Desktop effects could not be enabled"
So it's either troubleshoot this or look at Virtual Box....

[UPDATE] I finally broke down and read the help file... I stumbled upon this gem:
Under the section Support for Direct3D Graphics:

Prepare a Virtual Machine for Accelerated 3-D

Before you begin, make sure the guest operating system is Windows XP, Windows Vista, or Windows 7.

Isn't that swell.

Mozilla Weave .8 released

2009-11-04T14:06:00.001-06:00

Mozilla Weave .8 is out! Sync your bookmarks, history, passwords, etc. Mozilla Weave
The latest release looks more like optimizations than anything else. You'll need Firefox 3.5 or higher.
After Google killed off their addon that did similar synchronizations (my favorite part was the history sync), Weave was one of the best options.

Time server synchronization in Windows Server 2008

2009-11-03T09:22:00.000-06:00

There's been a change in the way you configure your time server synchronization in 2008. Previously you'd use the net time command. So in 2003 you'd do something like:

net time /setsntp:timeserver1.domain.com,timeserver2.domain.com

net time /set

In Windows 2008 you use the w32tm command:

w32tm /config /syncfromflags:MANUAL /manualpeerlist:timeserver1.domain.com,timeserver2.domain.com

w32tm /config /update

You can query your current settings with the following relative commands:

net time /querysntp

w32tm /query /source

For non-domain PCs the workstation defaults to time.microsoft.com. There's an "Internet Time" tab (Windows 7) in the date/time properties dialog box.
