"The Bullet gem is designed to help you increase your application’s performance by reducing the number of queries it makes. It will watch your queries while you develop your application and notify you when you should add eager loading (N+1 queries), when you’re using eager loading that isn’t necessary and when you should use counter cache."

"In the golden age of BASIC, it was easy for anyone to write a program. Now we offer you this exact same capability, but this time with the advanced features of the Nintendo DSi™ system… Many programs are included to ensure that you can fully enjoy using BASIC. The included programs were also written in BASIC, so you can add new features to them in order to enhance your games. You can also take the programs and data you create and convert them to QR codes that can be shared with friends who also have Petit Computer on their Nintendo DSi systems. (Programs included: 12 feature samples,5games, a character picture tool,a background screen creation tool,a graphics tool,and a picture-drawing tool.)" Interesting – especially the music-creation stuff, as Create Digital Music proved.

"An exposition of the philosophy of Carles as expressed on his weblog Hipster Runoff." Oh god, it's coming full circle

"Two music games got it right on the DS this year, both eschewing fancy controllers, instead focusing on the system’s touchscreen to present their engaging concepts: Rhythm Heaven and Maestro: Jump in Music." Ooh, sounds interesting – will have to hunt that down. (Via Simon Parkin)

"Egmont Press and Penguin Publishing will launch a range of children's books onto the Nintendo DS in a licensing deal with entertainment software company Electronic Arts (EA). It is the first time that children's books have been developed specifically for the Nintendo DS platform in the UK." Ooh, that's kind of awesome.

"Gemcutter is the next generation of gem hosting for the Ruby community. Instantly publish your gems and install them. Use the API to interact and find out more information about available gems. Become a contributor and enhance the site with your own changes." Apparently this is the next big thing, post-github not serving gems. Let's chase this trend for a bit.

"…it’s been a week and we’ve decided to not bring back the gem builder. It was a fun experiment but Jeweler and Gemcutter combined make it ridiculously simple to publish a gem. The gem builder use case (fork a project, make a change, publish a gem, install it) is now easier than ever using these tools." Which is all very nice, but a bit of a PITA for anyone who'd been depending on this. Still: gems.github.com will serve for another year.

"In Nokogiri  's are converted to whitespace, but they are not a normal space and aren't removed with the standard String#strip and friends." Needless to say, this is somewhat annoying. Thanks for fixing it, internet!

"Bayer’s DIDGET™ is the only blood glucose meter that plugs into a Nintendo DS™ or Nintendo DS™ Lite system. This unique meter helps encourage consistent testing with reward points that children can use to buy items within the game and unlock new game levels." Blood glucose monitor for diabetics that plugs into your Nintendo DS. Utterly awesome, and exactly what a new world of products should look like.

"I have realized that the traditional omelet form (eggs and cheese) is bourgeois. Today I tried making one out of cigarette, some coffee, and four tiny stones. I fed it to Malraux, who puked. I am encouraged, but my journey is still long." How have I only just encountered this?

Some jolly good stuff from Chris, notably "And I Saw..". I mainly like it, though, because he went and made a thing, and it definitely worked, and it's so, so simple.

"He probably thinks he is doing a community service but he is blatantly breaking the law and has to be dealt with. I would call him an eccentric." Community service yes; blatantly breaking the law, yes; 'has to be dealt with', really not sure about that. It's not like he was causing harm. Sometimes, the world is a funny place. Oh: and definitely, definitely "eccentric".

I can't really quote from it, but you need to read this; it's the most deliciously bonkers concept, and if they pull it off – which seems like it might just be possible, given the level of detail they talk about the game at – it could be properly magical. Lovely preview, too.

"Obama Says: Yes We Can is a Simon Says game based on Barack Obama's New Hampshire Primary speech, as later turned into song by will.i.am. Watch the game create a pattern of button and direction presses, and repeat that pattern correctly to score! The more you get correct, the harder the patterns become – can you keep up?" Oh blimey.

Lots of good stuff in here I didn't know about, all for your DS, and all not illegal. Hurrah for homebrew.

"With DS Reader you can read any e-book (or text file) on your DS. It even has a great little bookmarking function to keep track of your progress." Ooh.

"Game Trivia Catechism is a multiple-choice trivia game, testing your knowledge of video gaming. It can be played as straight trivia, or as part of a story that follows Al and Sally as they compete in the King of Game Trivia Tournament." Looks awesome.

"Current mass-market games present simulations of incredible fidelity. Many of these titles also push genre boundaries and offer new mechanics to players. The problem, argues Ubisoft’s Patrick Redding (FAR CRY 2), is that these two developments are disconnected. Game output appears information-rich, but how much of that information can the player actually use to play better, and how much of it is just there to be spectacular or cinematic?" I would pretty much kill to see this. Gah.

For those of you who might not be aware of its size, James has put the size of Gaza in context through comparing it to maps of other cities. Simple, effective communication.

"We need a National Videogame Archive. Luckily, we've just started one. We're going to preserve videogames for the nation. For better or worse. Forever. It's going to be brilliant…" Oh, that it is. Jonathan Smith on *every single bloody thing* that's perfect about Micro Machines 2 on the Mega Drive is a highlight so far.

Commander Keen on the DS. Heck yes. One of the first games I spent a *lot* of time playing.

"DS brut is an open source hardware prototyping platform for the Nintendo DS, developed by and for electronics enthusiasts, artists and game developers. By connecting the Nintendo DS to the outer world, the game console can be easily hooked up to a variety of sensors (e.g. GPS receivers) and can itself control all different kinds of actuators, servo motors and others."

"The technology will probably improve, but in lieu of the promised emergent web AI, we need to build more small tools, more games to bootstrap datasets, and more simple ways of encouraging people to play their part in the semantic web without ever having to explain what it is." tt++.

Fantastic presentation from Giles Bowkett, which is about generative music, art, shipping, Ruby, and building things for yourself.

"Paine does have a descendent, a place where his values prosper and are validated millions of times a day: the Internet. There, his ideas about communications, media ethics, the universal connections between people, the free flow of honest opinion are all relevant again, visible every time one modem shakes hands with another." Fantastic article

"At its core, what should this product be best at? When users think of this product, what is the central feature(s) that should spring to mind? Everything else is distraction, clutter, cruft."

"I think this vision of artistic expression as a form of collaboration is a truer description of the nature of game design than of any other medium, because video games are inherently interactive." Pliskin on Steve Gaynor, and the gap between the screen and the gamepad.

Portal-inspired homebrew game for the DS. Looks rather sweet, although not keen on collect-em-up mechanics.

"…then, after destroying his nano-network, as an admonition to the audience, extended [Arthur C Clarke's metaphor]: 'Any truly advanced technology is indistinguishable from garbage.'" Excellent summary of what sounds like a wonderful GDC Austin keynote from Bruce Sterling.

"'What we've done in MMOs and what we tend to lean toward is building an enviroment for the new player to explore that is essentially a safe environment… the newbie zone. For our explorative learners, we've given them safe zones to explore.' But that doesn't work for imitative learners." Excellent article on styles of learning, with particular attention to how MMOs teach players game mechanics.

"Very recently an anonymous poster on /b/ claimed to have hacked Sarah Palin's Yahoo e-mail account." 4chan members get into Sarah Palin's barely-disguised Yahoo mail accounts which she used for business.

Oh boy.

“I decided to create Flatshare fridge because there is nothing more disgusting than a dirty fridge in a shared flat,” he says. “At the time, I was living in such a flat!” Amazing.

"It occurred to me that if I could somehow tether a DSLR to an instant-on device like an Arduino microcontroller I would have less weight to carry around and could get more work done. After mentally spec’ing out what I would need, I realized the solution was right in front of me – because I bring it with me for Mario Kart wireless races on long night jobs – (In the manner of John Lasseter’s slow epiphany voice): “Use-the-Nintendo-D-S.” Duh." Oh wow.

Soulja Boy reviews Braid. Oh dear. (Although: much as I want to mock it, he is correct that time-rewind mechanics are, usually, a lot of fun in and of themselves. But still.)
