iOS 4 came out yesterday, and right after iTunes finished to install it on our iPhones we all wondered whether jailbreak was still possible. Yes, it is. Using an unofficial build of Pwangetool by Criminal90 floating around on the internet (UPDATE: official PwnageTool for iOS 4 is out) and a couple of tricks, I managed to jailbreak my iPhone 3GS and install Cydia on it. Check out the full tutorial after the break.

While they aren’t necessarily secrets, they are rather hidden features of the browsers that casual users might not even discover or need to explore. Though once revealed, they can be incredibly helpful. Macworld has posted four Safari 5 secrets that you might be interested in if you’re wanting the most out of Apple’s new web browser.

My friend ElasticThreads has just released three useful Greasekit userscripts that allow you to send links to your Instapaper account with a single mouse click, without having to move the cursor onto the bookmarks toolbar or invoke a shortcut. Available here, I’m using the holdClick version.

Great job.

Simple and effective tutorial by my friend Josh Helfferich.

Shawn Blanc has published two interesting posts (here and here) about the process of creating symbolic links on Mac OS X, following up to Gruber’s post from last week where he wrote about his configuration of Yojimbo’s library synced and backed up with Dropbox.

I’d like to cover two neat ways of playing around with Symlinks (for a basic knowledge about the subject you can head over the Wikipedia page) which involve the terminal, and I’ve found them very useful so far.

The ultimate post over at TUAW, which involves using the popular RCDefaultApp. Finally, we’ve got this thing working.

PrekeshC Deviantart user has released Lights, a graphical mod for Mac OS X which acts on the default traffic lights, making them..simply beautiful. I don’t have a good relationship with Mac OS’ normal traffic lights, so I went for it and applied the theme using Themepark. It just needs a logout to be set and running. So, from now on you’ll see them in every screenshot on MacStories, making my desktop setup sexier and lickable.

You know where to download them.

[Disclaimer: as always, be sure to backup the ArtFile and SArtFile files. If you're new to modding, Google is your friend. Last, the theme is Snow Leopard only. A Leopard compatible version will be released soon.]

Great tip from Dan Frakes over at Macworld. I think Quix might do the job as well.

I suppose you already know what Markdown* is. For those who don’t know, let’s quote a few paragraphs from John Gruber’s Daring Fireball:

Markdown is a text-to-HTML conversion tool for web writers. Markdown allows you to write using an easy-to-read, easy-to-write plain text format, then convert it to structurally valid XHTML (or HTML)

Thus, “Markdown” is two things: (1) a plain text formatting syntax; and (2) a software tool, written in Perl, that converts the plain text formatting to HTML. See the Syntax page for details pertaining to Markdown’s formatting syntax. You can try it out, right now, using the online Dingus.

The overriding design goal for Markdown’s formatting syntax is to make it as readable as possible. The idea is that a Markdown-formatted document should be publishable as-is, as plain text, without looking like it’s been marked up with tags or formatting instructions. While Markdown’s syntax has been influenced by several existing text-to-HTML filters, the single biggest source of inspiration for Markdown’s syntax is the format of plain text email.

For further information about Markdown, be sure to visit and read everything over DF’s project page. You’ll find some good stuff to get started there.

So, Markdown is a text syntax, geared towards readbility and “publishability” for the web. Writing in Markdown is simple and I would dare to say also “fun”, as it’s very easy to learn the basics and once you’ll get the hang of it, you’ll realize how useful it is.

I managed to define a pretty straightforward yet effective workflow for writing MacStories’ posts that includes using TextMate and Notational Velocity to keep everything formatted in Markdown and synchronized to the iPhone as well. Find out how.
