Acrylic insulated wires stink, for sure, but when they're stranded and micro-fine, they stink WAY more.

I may use this blog to post mainly iPhone or software related articles, but I am an electrical engineering student, and as an EE, I love me some good, clean hardware. Therefore, when my favorite pair of earbuds kicked the bucket the other day, my first thought went to the in-box iPhone headset and, more importantly, how much those earbuds suck. My favorite bang-for-the-buck earbuds EVER are Skullcandy Full Metal Jackets, primarily because I got them at TJ Maxx for $25. In general though, they have silicone pads that seal out sound, instead of the hyper uncomfortable iPod earbuds that fall out and sound like crap. I was super bummed when my FMJs broke, but luckily, the part that broke was on the plug end of the earphones. That is, both earbuds themselves still work fine, only the plug is dead. My thought was to cut the crappy iPhone buds off their cable (which includes a microphone and remote button) and graft on my beloved FMJs.

If you’re beginning to learn Objective-C like I am, things like this aren’t immediately obvious. I was trying to fool around with creating my own class, and I kept getting this warning
warning: no '-blah blah blah' method found along with an accompanying
warning: 'ClassName' may not respond to '-blah blah blah'

The really annoying part was that, despite these warnings, the code still worked just fine. Turns out, my issue was that I had this method in my class implementation (PolygonShape.m):

Cute puppy!My brother was just trying to embed a cute dog video in his tumblr blog yesterday but couldn’t figure out how to do it. The video was already in flash format, so it really isn’t too hard, but 99.99% of mere mortals have no idea that it’s easy. If you’re tech savvy, save yourself reading anymore and just go to any youtube video, copy the embed code, and replace the URLs with your own. Done. Otherwise, here’s how to do all that in just a few easy steps.

Error Starting Executable: No provisioned iPhone OS device is connected.
Error Starting Executable: No provisioned iPhone OS device is connected.

Ok, lame title, I admit it. That doesn’t change the annoyingness of the error though. Here’s the story: I sit down last night to watch the Oscars and get my feet wet developing for the first time in maybe a month or two. I go to debug an app on the device, you know, to see if I’ve still got it, and lo and behold a big hairy error pops up:

Here’s a goodie for all of you who don’t want to jailbreak your phone. Not that I know why you’d want that, and not that anyone like that reads this blog, but hey. it’s totally cool regardless. If you have an iPhone, and you use Twitter, you flat out owe it to yourself to try out TwitterFon (coral). First of all, it’s free. Better than that, it’s open source. Rock on! Second, it’s very well featured, even having a companion bookmarklet for Safari to send the current URL to a new tweet. It can post pictures to TwitPic, as well as update your current Twitter location with your coordinates. More impressive, however, is how it handles the basic functionalities of Twitter. In your main feed, you can click a post on an arrow appearing if it has links, getting a menu of those links (webpages viewable in-app, or you can click a button to open in Safari, # and @ links also clickable in-app). If you click a post on the body, you get a menu specific to that post – you can view the author’s feed/profile, retweet the post, mark it as favorite for later viewing, and so on.
