News from Skeezix:
Hey my friends ..

We're all hungry for our release units, and we all know everyone is dieing for more info and news, and we all know the boys are too busy to fill our demands But there are a few of us devkit lads on board now, so likely some more info will get leaked.

This is unofficial; I'm not speaking for the devs, and may make errors. I'm not intending to step on the toes of any of the very fine devs for any of the devices (disclosure, I've got dev units of all of them!). Craigs statement about saying something that is true for only 3 days being bandied about for 3 months is ever so true It is also tough to post performance numbers without people thinking its a diss to the non-topmost machine. I don't want to say that, since there are other factors (price, portability, screen preferences, add-ons, support, controls, weight, and so on.)

You might recall my past thread http://www.gp32x.com/board/index.php...opic=44373&hl= comparing gp2x to GP2x Wiz. See that for some commentary on what is accurate or inaccurate for those tests (ie: optimized code on gp2 versus unoptimized code on the Wiz, including SDL versus framebuffer, meaning the Wiz numbers are artificially lower and the gp2x ones are pretty high, so the Wiz should actually perform higher in relation to the gp2x than I showed.) Defining a 'fair' benchmark is hard since everyone has a different idea (all running at their best or worst? the type of test.. be it math, graphics, bus intensive .. it is easy to have a test that hits a weakness in one but a strenght in another, and is that a fair thing (typical use) or a cheat (atypical use)? Hard questions.)

Suffice to say my number is a _SINGLE_ (yet repeatable) test; a good benchmark is comprised of many benchmark tests so you can get a good picture from many perspectives.. not just a 'throwing this out there' number.

Still, it is a pretty telling number sometimes as well!

All that said..

Given OutcaST (an emu for which many of you have seen and used for some 6+ years from me in various forms), in a emulated CPU-torture test. (ie: Atari ST sitting at the GEM desktop with a stock TOS image will be in a tight CPU grind loop.) Doesn't really hit the ST's graphic system hard or the like, but the ST wasn't really a complex machine for graphics anyway. So it tests the emulation pretty well, in a situation that makes the mu perform worse than average. (ie: If it normally woudl run 60fps for a game, it'd run this GEM situation at 40-45fps at a guess.) Its also easy to auto-boot into, so no keyboard or audio or the like making the test more situational.. its pure out emulation with the machine not even trying to play audio.

GP2x stock F100, 200MHz IIRC. Highly optimized code.

GP2x Wiz dev unit (not final hardware but pretty close); The code is on GPH slow software only SDL. (no acceleration.) 533MHz.

Pandora Mk2 (version 1.1) devboard; 500MHz. Notaz quick SDL port using framebuffer. ie: Not optimized, but I think its prolly better than the GPH version on the Wiz. (GPH stuff tends to be slower for some reason, perhaps they don't compile with optimizatoins on in the compiler, or add debugging stuff, or the mouse support is in the way, or something.)

Sony PSP original FAT version. Not optimized for multi-cpu core, not really using the separate GPU for anything in this test. (ie: alpha blendsing UIs and such are in the code, but not during this test.) Essentially the PSP is chugging along at 333MHz if memory serves.. I don't recall if I'm clocking down or not in this case .. didn't loo back at the code to see.

Latest version of Outcast fro mthe gp2x, converted crappily to SDL on the non-F100 machines.

GP2x 49fps

GP2x Wiz 70fps

Pandora dev board mk2 180fps

Sony PSP 53fps

During actual game emulation the numbers are all higher by about 20-25%, but thats out of scope for this.

It is hard to explain the pandora being so far out in front of the others; my guess is the less congested bus, the processor being a multigenerational gap (the Pandora CPU is a far far newer design than in the GP2x), and the big cache on the CPU in the pandora.

Note my comments above; the 70 versus 49 (Wiz to gp2x) may not seem so impressive in relation to the pandora, but going back to the origiunal post I was pretty impressed. The Wiz _IS_ a snappy beasty (and this is a bit of a torture test, not a typical emu gameplay test!), so it is a very exciting device.

The Pandora is freaking goddamned fast.

Meggy Jr RGB Programming Guide and libraries

MAKE Magazine

- 9 hours and 20 minutes ago

EMS Labs has released PDF-documentation and some new programming libraries for their Meggy Jr RGB handheld game development platform. The Programmable Guide is really well-done, clear and concise. Even I can almost figure it out. The code libraries (The Meggy Jr Library) provide a software interface to the Meggy Jr hardware and macros and functions (The Meggy Jr Simplified Library) that float on top of that. The Meggy Jr Simplified Library allows you to get started quickly without having to deal too much with understanding Display Memory or the nuts and bolts of communicating with the hardware. It also simplifies some of the excesses of the Arduino environment, so in the words of Windell: "you can just use the darned thing."

I won't say that it wasn't an extreme disappointment that only one camera, the Kodak, was able to shoot with proper white balance in this situation and offer us colors as they really look (you'll have to trust me on this one). The other cameras compensated poorly, possibly metering the diffused light as tungsten light, and producing a fairly cold image because of it.br script type="text/javascript" charset="utf-8" galleryPost('camerabattlemodo', 6,''); /scriptbr Other than the color, you can't make out much from the wide shots. But if you blow the images up to their native resolution, there are huge differences. Even in the web-compressed images here, it's obvious that Canon captures the most detail:br img src="http://cache.gawker.com/assets/images/gizmodo/2008/12/canoncookies2compressed.jpg" width="807" height="440" style="display:block;float:none;" //p pIt's basically a tie between Sony and Kodak for second place. Here's what Kodak looks like:br img src="http://cache.gawker.com/assets/images/gizmodo/2008/12/kodakcookie2compressed.jpg" width="807" height="466" style="display:block;float:none;" //p pAnd then there's a pretty hard drop in quality. Panasonic comes in a solid last place here:br img src="http://cache.gawker.com/assets/images/gizmodo/2008/12/panasoniccookie2compressed.jpg" width="807" height="384" style="display:block;float:none;" //p pYou can fix the color by manually choosing a smarter white balance (color temperature), or adjusting the balance in post. But you can't get the texture of those cookies back. Big win for Canon here./p pstrongMotion Photography/strongbr It's no secret that many point-and-shoots are horrible for capturing the spontaneity of a child or pet, in part due to focus lag and often an additional wait before the shot is actually taken. While DSLRs are the best solution, I wanted to see if any point-and-shoots could rise to the challenge of capturing some action./p pSo I put them to the test on a Chicago side street where cars get up to 15-20mph. After repeat testing on each model, once again, we had a clear winner. Trouble is, it's Panasonic, loser of the resolution match! Panasonic features more shooting settings than any of its competitors, so my guess is that they spent a lot of time on optimizing at least this particular preset optimization.br img src="http://cache.gawker.com/assets/images/gizmodo/2008/12/panasonicmotion.jpg" width="807" height="518" style="display:block;float:none;" /br The remainder of the competition was fairly close, and I can't say that even the Panasonic model will capture any incredible sports action photography. But I will say that the Nikon and Samsung seemed to lag more than the others from button press to shot acquisition. They both tended to have the blurriest shots as well. Here's a typical result of the Nikon:br img src="http://cache.gawker.com/assets/images/gizmodo/2008/12/nikonmotion2.jpg" width="807" height="556" style="display:block;float:none;" //p pstrongVideo/strongbr Like high-speed photography, point-and-shoots aren't fundamentally designed for video. But then again, since they all shoot video, people have begun using them more frequently than they ever used their bigger, more specialized camcorders, so a test was necessary./p pAfter playing some billiards, I found Canon's image, though not technically the highest resolution, to be the best. A point as well to its realistic sound capture of ball on ball action.br img src="http://cache.gawker.com/assets/images/gizmodo/2008/12/canonvideo.jpg" width="807" height="476" style="display:block;float:none;" /br Second place goes to Kodak. Even though you can make out a great deal of grain on the table's felt surface, it also captures a relatively sharp, pleasantly contrasty image when you examine each ball.br img src="http://cache.gawker.com/assets/images/gizmodo/2008/12/kodakpicnewsss.jpg" width="807" height="445" style="display:block;float:none;" /br Last place? This title is, once again, reserved for Panasonic. For some reason, the camera interpreted the red table as some sort of blurry pastel. And the sound was a like a fast food drive-through speaker.br img src="http://cache.gawker.com/assets/images/gizmodo/2008/12/panasonicvideo.jpg" width="807" height="454" style="display:block;float:none;" //p pstrongFlash/strongbr We've all been there. It's late. A friend is in town. Your cameraphone can't hope to capture a shot in your drunken stupor, especially as you're hanging out in a smokey bar. I'd loved to have recreated this scene precisely in its brilliance, but instead I opted to take pictures of my cat with the lights low.br img src="http://cache.gawker.com/assets/images/gizmodo/2008/12/sonyflash.jpg" width="807" height="529" style="display:block;float:none;" /br It's an unfair challenge for a small-lensed, small-chipped camera to capture a decent picture in low light, even with flash as a crutch, but the Sony did as well as I could have hoped, illuminating my subject and her background alike, lacking the hotspots of most flash photography./p pThe other cameras were predictably mediocre, but the absolute worst at handling flash had to be the Nikon. Not only did it give my cat a washed-out glow, but it didn't even consider properly exposing that obnoxious pile of boxes behind her. The shame.br img src="http://cache.gawker.com/assets/images/gizmodo/2008/12/nikonflash.jpg" width="807" height="540" style="display:block;float:none;" //p pstrongWeird Features and Gimmicks/strongbr img src="http://cache.gawker.com/assets/images/gizmodo/2008/12/samsung-tl9.jpg" class="center" style="display:block;" /None of these items should probably determine your buying decision, but I wanted to mention a few of the more...interesting features of the cameras. The Samsung TL9 has a set of snazzy analog dials on top that display battery life and remaining memory like a car's dashmdash;plus it plays music and movies. The Panasonic has categorized an Intelligent Auto Mode that gives a lazy but informed user a nice way to tell the camera, "hey, you may need to boost the ISO," without messing with any other controls or gimmicky menus. The Nikon will warn you if a subject's eyes are closed. The Canon has ditched the standard up, down, left, right menu dial for a spinning ring...that's bold, if not always intuitive. And Sony will shoot in 16x9 or stretch images to that ratio for quick HDTV slideshows. Plus, smile/face detectors are everywhere. How did we ever take pictures before boxes enclosed a loved one's face?/p pstrongSo What Should You Buy?/strongbr After all my testing, I'd recommend the Canon SD790. Sure, it didn't win every category, but it won the one that counts mostmdash;detail. It came first in the video category. And it never ever fell flat on its face./p pMaybe this conclusion sounds a little too clinical to you. If so, let me say that there are less tangible elements I appreciate about the Canon SD790: It includes the best built battery charger and it is the only model tested to sync with a computer via mini USB (as opposed to some annoying proprietary cable or dock). On top of those, it always seems quick to capture a shot after I pressed for the shutter, though it's still not nearly as responsive as my prosumer DSLR. The one thing I'd ask for in this camera is a more powerful zoom lens./p pIf you know an extreme technophobe, you might tell them about the Kodak M1093. It offers the simplest shooting experience with one button to choose a photo mode, one button for flash toggling and one button to actually take a picture. Digital cameras don't get simpler than that, and I have to admit, as the cheapest model in this roundup ($200), with the least techie brand name, it performs better than I expectedmdash;though it does have a propensity to bump the ISO, producing some unwanted noise./p pBut as for the Sony W170, while it does feature the widest angle lens with 5x of zoom, it's clunky in the hand and rarely brilliant in quality. As for the Nikon S560, it takes mediocre shots. The Panasonic FS20 is inconsistentmdash;bordering on horrendous much of the timemdash;and features a small screen and a dated interface. Meanwhile, the Samsung TL9 just completely fails to impress me./p pSo go ahead, pick up the Canon. It seems the company's overwhelming market share is well deserved. Or don't. I won't lose sleep or anything. Just don't come crying to me when all your pictures look like crap./p br style="clear: both;"/ a href="http://www.pheedo.com/click.phdo?s=c1a975b9131882296246399e780f880dp=1"img alt="" style="border: 0;" border="0" src="http://www.pheedo.com/img.phdo?s=c1a975b9131882296246399e780f880dp=1"//a img src="http://www.pheedo.com/feeds/tracker.php?i=c1a975b9131882296246399e780f880d" style="display: none;" border="0" height="1" width="1" alt=""/div class="feedflare" a href="http://feeds.gawker.com/~f/gizmodo/full?a=UD6vGN1K"img src="http://feedproxy.google.com/~f/gizmodo/full?d=120" border="0"/img/a a href="http://feeds.gawker.com/~f/gizmodo/full?a=Wtdzgbo9"img src="http://feedproxy.google.com/~f/gizmodo/full?d=41" border="0"/img/a a href="http://feeds.gawker.com/~f/gizmodo/full?a=prZIRpc4"img src="http://feedproxy.google.com/~f/gizmodo/full?i=prZIRpc4" border="0"/img/a a href="http://feeds.gawker.com/~f/gizmodo/full?a=z2R519Xk"img src="http://feedproxy.google.com/~f/gizmodo/full?i=z2R519Xk" border="0"/img/a /divimg src="http://feedproxy.google.com/~r/gizmodo/full/~4/CrXUNBcOjJ4" height="1" width="1"/

This is rather surprising considering Apple discontinued the 4GB model just a couple of months after rolling out the iPhone - is there something Cupertino knows that we don't? Could this be the beginning of the end for Windows Mobile smartphones, as Apple plans to occupy both the high-end and low-end range of the market? Only time will tell, and it will be interesting to see just how many people pick up a $99 iPhone, never mind that it doesn't even pack 3G connectivity and comes with a measly 4GB memory./p pPermalink: a href="http://www.ubergizmo.com/15/archives/2008/12/99_iphones_coming_to_walmart.html"$99 iPhones Coming To Wal-Mart?/a from Ubergizmo (a href="http://www.ubergizmo.com"US/a, a href="http://www.ubergizmo.com/fr"FR/a) | a href="http://www.uberbargain.com/"Good deals/a | Hot: a href="http://www.ubergizmo.com/15/archives/2008/11/blackberry_storm_review.html"Storm Review/a/p pmap name="google_ad_map_081204090614" area shape="rect" href="http://imageads.googleadservices.com/pagead/imgclick/081204090614?pos=0" coords="1,2,367,28"/ area shape="rect" href="http://services.google.com/feedback/abg" coords="384,10,453,23"//map img usemap="#google_ad_map_081204090614" border="0" src="http://imageads.googleadservices.com/pagead/ads?format=468x30_aff_imgamp;client=ca-pub-7335032025195922amp;channel=9684588219amp;output=pngamp;cuid=081204090614amp;url=http%3A%2F%2Fwww.ubergizmo.com%2F15%2Farchives%2F2008%2F12%2F99_iphones_coming_to_walmart.html"//p pa href="http://feedads.googleadservices.com/~a/7K8by0GY-xSsntrByzG7g73vC2E/a"img src="http://feedads.googleadservices.com/~a/7K8by0GY-xSsntrByzG7g73vC2E/i" border="0" ismap="true"/img/a/pdiv class="feedflare" a href="http://feedproxy.google.com/~f/ubergizmo?a=6jrH7p2A"img src="http://feedproxy.google.com/~f/ubergizmo?d=41" border="0"/img/a a href="http://feedproxy.google.com/~f/ubergizmo?a=8AmvsnLN"img src="http://feedproxy.google.com/~f/ubergizmo?i=8AmvsnLN" border="0"/img/a a href="http://feedproxy.google.com/~f/ubergizmo?a=dx6jIJgk"img src="http://feedproxy.google.com/~f/ubergizmo?d=52" border="0"/img/a a href="http://feedproxy.google.com/~f/ubergizmo?a=bM50Ni3S"img src="http://feedproxy.google.com/~f/ubergizmo?i=bM50Ni3S" border="0"/img/a a href="http://feedproxy.google.com/~f/ubergizmo?a=ebw0h8ti"img src="http://feedproxy.google.com/~f/ubergizmo?i=ebw0h8ti" border="0"/img/a /divimg src="http://feedproxy.google.com/~r/ubergizmo/~4/FyqqtloNUW4" height="1" width="1"/

( a href="http://www.networkworld.com/buyersguides/guide.php?cat=881344"Compare/a blade servers.) I/O cards don#39;t have to be included in each blade because they are accessed over a shared fabric. Memory and processors are still fixed parts of each blade, however, limiting flexibility. If extra memory is needed, you may have to buy another blade instead of just accessing the memory of another one, Claunch said./pp page="2" class="ArticleBody"quot;The next step in this progression is the introduction of technology to allow several blades to be merged operationally over the fabric, operating as a larger, single system image that is the sum of the components from those blades,quot; a Gartner PowerPoint presentation states. quot;The fabric-based server of the future will treat memory, processors and I/O cards as components in a pool, combining and recombining them into particular arrangements to suit the owner#39;s needs.quot;/pp page="2" class="ArticleBody"For example, an IT shop could combine 32 processors and any number of memory modules to create one large server that appears to an operating system as a single, fixed computing unit. This approach also will increase utilization rates by reducing the resources wasted because blade servers aren#39;t configured optimally for the applications they serve. quot;This evolution will simplify the provisioning of capacity to meet growing needs,quot; Gartner states./pp page="2" class="ArticleBody"ema target="_blank" href="http://www.networkworld.com"Network World/a/em emis an InfoWorld affiliate/em/p/divbr style=clear: both;/ a href=http://www.pheedo.com/click.phdo?s=df71c541163ff94462c983fa91abb9c5p=1img alt= style=border: 0; border=0 src=http://www.pheedo.com/img.phdo?s=df71c541163ff94462c983fa91abb9c5p=1//a img src=http://www.pheedo.com/feeds/tracker.php?i=df71c541163ff94462c983fa91abb9c5 style=display: none; border=0 height=1 width=1 alt=/
