Skyward Sword

For Christmas I got Skyward Sword. Unfortunately, my wife didn't get my email about the game+controller bundle, so I had to pick up a Motion Pus controller before I could play it.   I've played about 4 hours so far, so consider this a very early review.   I will say there's been an awful lot of dialog in the game so far, on top of the intro backstory movie. I just hope they do something with Groose, or that was a whole whack of dialog which wasn't that necessary.   The game - it's Zelda

Glitch - a free MMO

Warning: if you have addictive game tendencies - don't start playing Glitch (more on why later).   Glitch is an odd game - and not just because you squeeze chickens to obtain grain. It's a free-to-play game which you can play without paying. Unlike a typical FTP games, you can't use real money to buy in game resources, reduce action times, or additional actions. Real money may only be used to buy cosmetic items like clothing and furniture. (Well, it can be used to buy teleport tokens, whic

Dragon Age Legends

When I signed up for Google+ I was happy to see that the games (and their notifications) were segregated from the main feed page. Although I didn't join Facebook, my wife did, and her feed was clogged with games related posts. She spent a lot of time on Facebook playing games until she quit cold turkey. I told myself to avoid the games on Google+, and I managed to do it for a month.   It's all her fault . . . she joined Google+ and started playing Zombie Lane, so I figured I would play too,

Good tactics or just lucky?

As part of the "Welcome back" program Sony has given every PSN user a free month of PlayStation Plus - which gives discounts on downloadable content and some exclusive content. Well, I activated my free month and proceeded to download as much free stuff as I could, including several full games (including Oddworld Exodus). They might only last the month but they're free.   Then last week Magic the Gathering: Duels of the Planeswalkers was added as a free download for Plus. I played Magic over a

Angry Birds

There's a free Angry Birds beta available via the Chrome App Store. I've played through the first 21 screens and I can't understand why it's so popular.   This isn't to say that I don't enjoy it. I certainly had fun with this physics/puzzle game. But I also found the gameplay somewhat frustrating, and my tolerance and patience for failure is reasonably high. Thus, I imagine that most people would find the game very frustrating (confirmed by my wife), thus I am puzzled by why it's popular.

Why bother . . .

This is probably only of interest to potatohead, but I don't want to depress the Propeller crowd.   The Parallax Propeller is a pretty cool chip. Eight 32 bit cores running at 80+MHz with video output capabilities. A lot of people have said, that's cool let's make an emulator or videogames!   Except that ain't easy. Yes, the Prop has enough processing power to emulate an 8 bit CPU at a reasonable speed except... There's no external memory bus, so you only have 32K of RAM for everythin

If I were a rich man...

Stern has announced that their next pinball will be TRON Legacy. I'd really like to get one, but spending $5K (+tax) on a game is a little more than I can justify.

Portal 2

I think the first game I bought for my PS3 was the Orange Box - basically to get Portal (although I've played a good chunk of Half Life 2 while my wife wasn't around). So while I'm not a major fanboy, the game is definitely one of my favorites.   Anyway, I knew P2 was coming out, had watched some of the videos, but hadn't really thought about getting it until today when ars reminded me that P2 has a co-op mode. Then something clicked - P2 co-op & long weekend. What a better way to spend

Pinhole Panorama camera idea

Roughly based on: http://blog.makezine.com/archive/2010/03/weekend-project-pinhole-panoramic-c.html   The design point is to make a 120 roll film cyclindrical panorama camera. My original idea was to make one with a 90 degree vertical field of view & 135 degree horizontal FoV, with the idea that a full 360 degrees would be covered in 3 shots. But then I got to thinking about adding a zenith shot (which would be easy if the depth of the camera was half the height), so up'd it to 105 degre

Collateral Obsolescence

About a dozen years ago I (with the bank's assistance) bought a house. The bank was so gracious for my business they gave me a computer, or rather a gift certificate for the IBM PC Store for an amount equal to their bargain basement Aptiva Isparati. The computer was a dog (Citrix MediaGX processor) but it was marginally better than the 486DX2-66 I had. (And I knew the computer was a dog when I bought it, but as it was effectively free I didn't complain. However, I didn't throw good money aft

Insignia (Chumby) Infocast

While on a 2 week vacation to watch the Daytona 500 (my wife is the NASCAR fan), I picked up the Chumby powered Insignia Infocast (in spite of none of the Best Buy drones knowing what one was). Now that I have it, I'm wondering what I'm going to use it for.   It certainly will function as an 8" 800x600 digital picture frame, just stick in an SD card. Ideally I'd like to pull stuff from iPhoto or Picassa (since that's where I store photos now). It can also play back videos, although the chal

Dealing with duplicate backups

I love making backups onto external drives. Plug it in and use EZBack-it-up (now I'm using robocopy) to do a simple copy of every file and every subdirectory onto the external drive. Then put that drive on the shelf until it's time to restore a file or do another backup. Not good for a bare-metal reinstall, but great for a basic file recovery solution. (Also useful when the internal drive gets full and you need to delete some large media files.) And when the drive gets full, buy another driv

next gen copy protection

Since the PS3's security structure has fallen, I'm left to wonder whether it's even possible to create a secure console. Secure in the sense that it prevents piracy. And if I was Sony/Nintendo/Microsoft I'd be talking to fail0verflow to contract them to help design it.   Copy protection basically comes down to making something which can be read (by the console) but not written (by anyone other than the creator). The PS1 used some sectors with zero'd ECC. So the PS1 drive could read the dat

Playing GT5

This past weekend my step-brother-in-law gave me GT5 and a steering wheel and I've been playing it every evening. And although I'm not a hardcore racing sim driver (Mario Kart is more my style - foot to the floor) but I am having fun along with some frustration.   I'm currently up to level 8 and my current effort is trying to get around the Nuerburgring in less than 11 minutes. I'm within 10 seconds and that's with a few bounces off the Armco barriers. So I'm confident I'll get there with p

Team Twiizers does it again!

Via slashdot Team Twiizers (now known as fail0verflow) has made some significant strides in demolishing the security of the PS3. (By discovering a flawed crypto implementation - allowing the private keys to be recovered.)   It makes me wonder if it is possible to implement a truly unbreakable anti-piracy mechanism.

StarCraft 2 demo

I've just played through the StarCraft2 demo for the n'th time. Part of me wants to like it, but I can't get past the basic nature of RTS - having micromanage everything in real time.   I have to say I never played the original StarCraft. The closest RTS I've ever played was Pikmin. But the resource management on that one is pretty minimal and there's no need to protect your base.   Anyway, although I like the single player storyline, I'm just having problems trying to optimally use my ba

Happy birthday Xbox 360, where's your successor?

Cnet published an article discussing that the Xbox 360 has reached its 5th birthday with no successor for it or its competition in sight.   The answer is simple: it's all about the money.   Microsoft and Sony initially sold their consoles at a loss to gain market share. Now they make a profit, so the more they sell now the more profit they make. Microsoft also rushed the Xbox 360 to market, which got them initial share but cost them in reliability and replacement. Microsoft and Sony have a

Panoramic photos & horizon detection

One side effect of buying a new camera (Panasonic FZ40 to replace a Canon S3) is I've rekindled my interest in panoramic photos. Using Hugin (free software) a series of overlapping photos can be assembled into one giant image. Doing this requires identifying "control points" which either link to photos together (i.e. this white dot on photo 1 is the same as this white dot on photo 2) or identify horizontal, vertical or straight lines. With enough control points, the software can determine the

Fast Discrete Hartley Transform part 2

I know I said last year that it was debugged, but it wasn't. Now it is. But it's now checked out and verified from top to bottom including deriving the algorithm, the pseudo-code implementation, and the actual Propeller code. Backed up with spreadsheet comparisons between the algorithm outputs at each stage versus the base transform.   And it's still fast! 256 samples takes 645,520 cycles (31.7 KHz) and 1024 samples takes 3,534,656 cycles (23.1KHz) with full 32 bit precision.

Piracy is too damn easy

This weekend the family and I got together with the in-laws for a Canadian Thanksgiving dinner. We arrived early and ended up spending the time watching "How to Train Your Dragon". About halfway through, their son comments, "pretty good quality for a download." I'd figured we were watching a DVD instead of a Blu-Ray, even though they had a PS3. But then I realized he wasn't saying this was streaming from Netflix, but it was pirated (via LimeWire, which he was using to download Gladiator).

Apple ][ versus CoCo

Back in the day my family owned a CoCo (partially because my Mom worked at a Radio Shack computer store at the time, so got a discount), but at school I user Apple ][s (pluses and Es). Unlike the C64 (or the Atari 8 bit computers), neither the CoCo or the A2 has any sound or sprite hardware. Yet the A2 had a huge library of games, and I have to ask myself why.   I think it was the disk drive. Although a disk add-on existed for the CoCo, cassette tapes were still very popular. And, unlike

Stupid Propeller Tricks

The Propeller has two "native" languages. Like any microprocessor, Propeller Assembly (or PASM) is the human version of the machine code executed by each processor. But like 8-bit computers of old the Propeller has an onboard interpreter. However instead of being a version of Microsoft BASIC, this interpreter is for a new high level language called SPIN. The SPIN interpreter itself is written in PASM, but the initial code for any Propeller program is in SPIN (which can then start additional

PS3 OtherOS class action update

All files available from: http://dockets.justia.com/docket/california/candce/3:2010cv01811/226894/   Well Sony has fired back at the Amended Complaint with two barrels: a Motion to Strike and a Motion to Dismiss. I haven't gone too far into them, but Sony's first point is the five plaintiffs have different complaints and one didn't even install OtherOS! So Sony's point is if the the five plaintiffs are representative of the class, as a whole, then the court can't assume a class really exists

AES-128 on the Propeller

One of the knocks against the Propeller is it has no code protection, unlike PICs and other microcontrollers with onboard EEPROMs. And although the protection may be less than perfect, I can understand many companies are not willing to have their IP in an easily accessible state.   IMHO the way to remedy the situation is to include a small amount of onboard OTP storage for an encryption key and integrate a decryption routine into the bootloader. But for that to work someone (i.e. me) needs t

PS3 review - Blur

So after performing some housekeeping on my PS3 (didja know that you can assign downloaded games an "Album", and then select "Group by Album" - so now my purchased games are in a separate folder) I downloaded the multiplayer demo of Blur.   First, big kudos to Activision for releasing a multiplayer demo which actually allows you to play as if you bought the game (up to level 10 at least). That's right - no timing out on the last lap or limited play time. You can really get a good feel for wh
