Have you ever written this in a forum, addressed to a software developer: “I have $50 here which I’ll totally give you if you make this app”? No, of course not, because that would make you a thoughtless individual — we all know that software costs way more than that to develop.

Take NumLock, for example. It’s exactly the kind of app that forum-begging is made for. It turns back on the num-lock that Apple removed from its keyboards for seemingly no reason other than the aesthetic. How much would you promise a developer that you’d “totally pay” for an app to re-enable the number keypad? Well, now you can put that money where your, uh, keyboard is, and pitch in to DenVog’s cheap-as-chips Kickstarter campaign.

Rovio’s original Angry Birds game for iOS has today been updated with 15 new Bad Piggies levels, and is now available for free for the first time ever on both iPhone and iPad. The incredibly popular title was first introduced to the iPhone back in December 2009, and it’s been priced at $0.99 ever since.

But if you’re not one of the many millions who have already downloaded it, now is the perfect time to grab it.

Flexibits’ fantastic calendar app Fantastical has reached v1.1. In numerical terms, this is just the addition of 0.1 to the original 1.0. But in terms of app goodness, it’s much more hugerer.

Infinite Dreams has come a long way since we first discovered their virtual-pottery app, Let’s Create Pottery HD, at the App Store in 2010. They’ve since created a smash-hit tower defense game, and unveiled the first touchscreen coin-slot arcade console based off an iOS game.

Now, with the help of 3D printing, they’re turning virtual pottery into the real thing.

Social media iOS app, Path, updated today to version 3.0.1, adding some new features to the purported all-in-one personal social network’s iOS app. The update adds private messaging along with photo filters and stickers designed by a small group of indie artists for the app.

The sequel to classic puzzler/adventure game, The 7th Guest, is currently in development for iOS, Mac, Android, and Windows PC, according to Polygon, who spoke with Trilobyte Games’ co-founder, Charlie McHenry, today. The game should feature the atmospheric horror and clever puzzles that the series, which includes The 7th Guest and The 11th Hour, is known for. The 7th Guest 3 will be set in the Stauf Mansion, as well, and should be in real-time 3D, instead of that pre-rendered stuff of the past. Whew.

Miguel de Icaza isn’t a casual PC user. He’s a life-long Linux user whose main claim to fame is the creation of GNOME, a completely free desktop environment for Linux and other Unix operating systems.

But de Icaza no longer bothers with Linux. He’s abandoned the platform for a Mac.

Use Evernote on iOS? Wish it had proper saved searches? Or note links? Wish it was a little faster to browse and find what you’re looking for? Then you might want to take a look at the rather excellent Clever HD for iPad, a full-featured Evernote client which could even replace the official app on your iDevice.

Sharp has this morning announced a ¥10.4 billion ($112 million) investment from Samsung that will provide the latter with a 3% stake in the company. It makes Samsung the biggest individual shareholder in the Japanese display maker, and secures its access to Sharp’s LCD panel supplies.

The investment comes at a time when Sharp has been struggling. The company received a $4.4 billion bailout from the banks in October 2012, and its iPad display orders from Apple were recently cut as consumer demand shifted to the smaller iPad mini, which Sharp is not involved with.

One of the cool things I loved about Apple’s Mail.app was the way it provided a visual preview of the attached files that came in my email. It was nice to be able to see exactly what was sent along with the email.

Some folks, however, might not dig this feature, and might want to turn it off. Maybe it helps them feel better, or they don’t need the visual preview. For whatever reason, if you’re one of those people, here’s how to turn it off.
