The Most Expensive Desktop Computer I Have Seen - Dell Poweredge 2900

Filed under: Hardware — timwang @ 01:25:36 pm

First of all, the title cheated, it's a server, but designed in a desktop layout. Our IT department recently received a new desktop server-Dell Poweredge 2900, for a department in the faculty. Since it is "the most expensive" desktop computer (It cost over $10K) I have encountered so far, therefore I better take a few pictures. I am so far quite impressed by Dell's Laptop quality but never knew they can build a high quality server box with such an efficient design. The Power Edge 2900 is one of the newest and most powerful desktop servers in the market today. A lockable panel in the front prevents access to the hard drives and a small on-box LCD panel with color variations provide quick summary of the server status. The Dell Poweredge 2900 has a similar height as a normal desktop and 1/3 longer than a regular desktop.

The desktop server provide amazingly flexible storage options: you can plug in up to 8 SAS or SATA hard drives in hot-swap carriers. An optional flex-bay can be inserted in the lower of the two spare 5.25in bays above, with its own backplane and interface.

There are six easily removable fans providing a good access of air through the interior front to back, for the purpose of cooling the monster down: 5050 Xeon processor mounted on it, both sockets have dedicated fans and the (max. up to 48GB) memory slots also have dedicated fans.

It’s got a dual 93w hot-swap power supplies in case of one breaks down.

Unfortunately, it is "too noisy" for anyone to hide it under the desk. Therefore, it still needs to go into a server room. But it certainly got the "Ferrari" look.

Crysis vs. Unreal Tournament 3 - My Game Confession

Filed under: Games — timwang @ 10:46:01 pm

Crysis vs. Unreal Tournament 3 (UT3), there are many discussions on this topic; I have no means to pretend to be the “game expert” here. Since I am a First Person Shooting (FPS) game fan, I intend to share my opinions via this blog. I find many debates over this issue started on the wrong foot because this is really a personal preference. Therefore, I’d like to lay down my FPS gaming experience first so you know where I am coming from:

My first FPS game was the good old legendary Wolfenstein 3D, then I picked up Doom, then the Quake Series. During Quake II, I stopped playing the story line based FPS and moved on to multi-player FPS games. Quake II Mod-Rocket Arena (RA) was a solid starting point. I got really “sucked in” by the Quake III Arena Mod - Rocket Arena III – practicing rocket jumps and rail gun shots on Friday nights. After my RA clan dissolved, I started playing Counter Strike and Days of Defeat which are the MODs of Half Life. Then of course, that got migrated to CS Source and DOD Source (both are based on the Half Life 2 game engine). In between Quake III and CS, I also tried the Unreal Series: Unreal Tournament 2, UT 2004, and then UT 2005. I have also played Far Cry and F.E.A.R. My most recent attempt in FPS is Crysis and UT3. Yeah, in the meanwhile, I did graduate from high school and got into university and later on got a job.

Alright, now you know what I have played, here’s my opinion on these two games: I think Crysis is the winner simply because the game has changed the FPS dynamics not simply from the graphic and sound aspects as all the other games do (UT3 included). It has changed the gaming experiences by introducing new elements into the combat. Started from In UT 2004 and Battlefield 2, players can drive vehicles or airplanes; but starting in Crysis, players can modify the avatar’s speed, armor and visibility in the middle of a shoot off, which makes the game much more complex and fun. Although the whole “wheel menu” UI and "suit mode" remind me of the console games. On the other hand, I felt that Unreal Tournament 3 is just another UT game, the same old gameplay, nothing new really.

When it comes to FPS games, you can't ignore the graphic comparison, although I say it really depends on the hardware and other elements, but here are some side-by-side comparisons:
crysis vs ut3 avatar skin comparison
Cleary Crysis win this one, well, if you are only looking at "human" skin textures that is... There are lots of detail in the people and very dynamic facial expressions "grabbing the neck faces"...

crysis vs ut3 movement comparison

The physics between the two games are quite different since Crysis is aiming more at the real world battle simulations and Unreal Tournament 3 is aiming at the Sci-Fi “hover boards” style physics. Both are doing it well I think. But I still appreciate more on the running and gunning
effects in Crysis, with some nice blur effect.

crysis vs unreal tournament 3 weapon comparison
Weapons and Firing, since UT3 weapons are more built for science fiction, the fire effects are fancier than Crysis. E.g. Using the “Shock Gun” to shoot the light balls out and then use the beam to nail them for a wider range explosions, you can almost feel the air vibrates around you when you do that, really cool!

crysis vs unreal tournament 3 plants comparison
Plants comparison, well, not much need to say here, Crysis is a clear winner. Where the palm trees are so pretty you hesitate when you shoot in the woods because your bullets will break them apart...

crysis vs unreal tournament 3 avatar comparison
Avatar comaprison, both are well done, but I think the "power suit" in Crysis is the best looking amour ever.

crysis vs unreal tournament 3 lighting comparison
Lighting comparison, The Cry Engine is simply built for out-door natural light settings. It has the best lighting effects among all the FPS games I have played so far...

crysis vs unreal tournament 3 overall comparison
Both games have improved their graphics incredibly but I am still impressed more by the Cryengine 2 renderings. I found that some texture rendering in Crysis are purposely blurred to add effects and decrease processor demand. This is really neat when you have lower end machines. When I lowered the graphic settings down on both games, I experience that Crysis is a bit more playable than UT, but of course this really depends on the hardware settings. (FYI, I am using a Dell XPS laptop with the Geforce Go 7950 GTX graphic card)

In comparison to CS Source (Half Life 2), the game settings in Crysis are much more complex, maybe even a little unnecessary according to some players. Many FPS fans may complain that the fancy objects in Crysis (trees, burning cans, and metal fences) are overkill in a game, well, true, but I think this make the game more realistic?

I also find the shadowing effects are not as sharp as in Crysis, say in the “Under City” level. Anyway, in conclusion, I value the gameplay in Crysis a lot. The “add-on” effects to the avatar by the “maximum strength” of the suit are just revolutionary. UT3 is a wonderful game too but it’s nothing like Crysis. HOWEVER, I believe UT3 will have a slightly bigger players community because there are way more documentations and video tutorials out there for the game modifiers than Crysis.

Ironically, neither of the two games are sold well in the past couple of months, they are both losers in comparison to Team Fortress 2 based on the box offices. Reasons? Same as I stated in the beginning, TF2 focus even more on game tactics and character buildings. Darn, looks like I am going back to the Source-based games...

PS-I am also a Real Time Strategy (RTS) game fan, well more like the "Blizzard" fan: Diablo II, Warcraft II, Starcraft, Warcraft III, Startcraft II(coming...). Well, there ought to be another confession I suppose...

PS2-Oh, yeah, my Massively Multi-player Online (MMO) game friends somehow read my blog and complained the still-not-completed-confession: Chuanqi (Legend, one of the earliest Chinese MMO game), WOW and EVE... If I ever get to them...

Thinnest Laptop – Apple MacBook Air

Filed under: Laptop-Notebook — timwang @ 06:03:54 pm

One of my co-worker is looking for a “small and thin” laptop and I think her search is over. Apple MacBook Air was announced at Mac World this week. Check out the dimensions first: 12.8" wide, 8.94" deep, and 0.16" to 0.76" thin and weight: 3.0 lbs (1.36 kg).

Thinnest Laptop in the World - MacBook Air

The entire laptop is only 0.76” thick! That is the base + lcd for less than 2 centimeters! This makes this laptop to be the thinnest laptop in the world today. But the immediate trade off is that there is no CD/DVD drive attached and only one USB port. However, the MacBook Air seems to have a new generation of wireless solutions: 802.11n2 and Bluetooth 2.1 + EDR wireless technologies. Remote Disc option allows you to easily access other Mac computers’ DVD drive.

thickness of the thinnest laptop in the world - MacBook Air

To me, the real eye catching component is the multi-touch trackpad, yeah, just like the iPhones…

Another thing worth to mention about the “thinnest laptop” is the 13.3”” widescreen LED supports resolutions up to 1280 x 800. This means you gonna get crystal clear images and good coloring from it.

What’s need to be noticed is the CPU power is not so great considering you can only upgrade it from 1.6GHz to 1.8GHz, and the price nearly doubled (originally at $1799, now $3,098). But you also get an extra of 2GB RAM memory though.

Here are the full specs of the default model: $1799
13.3" Widescreen LED Backlit (1280 x 800)
Intel Core 2 Duo 1.6GHz and 1.5GHz (4MB L2 cache, 800MHz frontside bus)
1.8" 80GB HD (same type in iPod) or 64GB SSD option
Multi-touch trackpad
2GB RAM (667MHz DDR2 SDRAM)
Intel X3100 graphics
Magnetic latch
1 USB 2.0 port, Micro-DVI, Audio out (analog)
802.11n wireless
Bluetooth 2.1 + EDR
iSight camera built-in
37 watt-hour lithium-polymer battery
No optical drive built-in, but SuperDrive accessory available for $99

Gates Looking For a New Job - Last Day at Microsoft

Filed under: Microsoft — timwang @ 08:28:53 pm

In case you haven't watched this, a short clip put together for Bill Gates, to illustrate his last day at Microsoft, with a nerdy humor. Quite brilliant as matter of fact. The cast is incredible: Matthew McConaughey, Brian Williams, Steve Palmer (well, that's a given), Jay-Z, Bono (from U2), Steven Spielberg, George Clooney, Jon Stewart, Hilary Clinton, Barack Obama, and Al Gore. Here's the video:

This video was screened during Gates' farewell speech at CES 2007. A crucial part of the talk:

Gates outlined three major themes for the second digital decade-high definition displays with 3D experiences and high quality video and audio, connected services and the power of natural interfaces. Gates had a vision early of those themes, but his quest to make the Tablet PC, Media Center PCs and natural interfaces, such as speech and touch, more mainstream has not been realized.

Boston Digital Media Summit - A Bridge Between Playing and Learning

Filed under: Conference — timwang @ 08:02:52 pm

There is a really exciting event coming up this weekend: Boston Digital Media Summit. Check out the program schedule. There are quite a few interesting sessions that I would love to follow up with: Larry Johnson (CEO of the New Media Consortium) on Game-changing Immersive Educaiton Paradigms. Julian Lombardi (Chairman of the Board of Directors, Croquet Consortium) on The Croquet Immersive Education Platform. The summit focuses on how can games and 3D simulations facilitate learning. This would be a wonderful opportunity to realize (or debate on) the true values of the technologies like Second Life and Croquet in education. Unfortunately, there are other commitment so I will miss this event. But I will share the web cast on this blog if there is any.
