If you’re like me, you’ve had an iPhone, iPod Touch and/or iPad for a few years now and have probably amassed a fairly big collection of apps, both free and paid. Until last year’s iOS 5, this meant having to keep a local copy of each and one of them on the computer you used…

Printing in grayscale with AirPrint
Did you all think I was dead? Unfortunately for you, I am not. I’ve just been fairly busy with work and with my renewed interest in photography. Speaking of which, all of you should follow my Flickr photostream, which I update daily. So, you’ve got the shiny new iOS 4.2 on your iPhone 4 and…
How to use resizeTo in Safari (if it doesn’t work)
Many people are probably familiar with the fact that most browsers allow Javascript code to be entered in the address field. That’s the magic behind bookmarklets, which simply spare the user the hassle of manually typing long, convoluted and obfuscated Javascript statements. While it’s usually pointless to do so, there is one case in which…
Manual duplex printing on a laser printer
My laser printer, a Samsung CLX-3175, does not have any tool for automatic duplex printing. Achieving such result manually is not difficult, but may take some trial and error in order to get the settings right. That’s exactly what I’ve done, and I’m writing this post as a note to myself. Should it be useful…
Prettifying URLs with fake subdirectories using mod_rewrite
Lately, I have been trying to define a common basis for most of my web projects, since I often end up reinventing the wheel every time. I have tried a few PHP frameworks, but none of them tickled my fancy, but I have complicated tastes. I am known for reimplementing something from scratch rather than…
20 tips to run a business without committing suicide
Starting earlier this year, I have been a “professional” IT consultant (libero professionista in Italian.) In practice I mostly deal with web development and computer repairs. It’s what I’ve been doing for over a decade now, since I was still in school, only now I get to pay my own taxes (yay) and therefore I…
Fix broken IMAP attachments in Mail.app
I have recently started getting broken images in Mail.app. Often, when someone sent me relatively big pictures (over 1 MB in size), the image ended up being corrupted, with a smaller file size that one would expect. This results in a picture that’s visible up to a certain point, and then rest is usually filled…
Chords for “Soft Kitty,” from The Big Bang Theory
One of the funniest “inside jokes” of The Big Bang Theory is the song that Sheldon’s mom used to sing to him when he was sick. It’s featured in three episodes, as you can see here: httpvh://www.youtube.com/watch?v=lqSmzGj_sQc The song is, like most lullabies, very simple. I came up with the chords earlier today, while jamming…
Speed up connections to IRC servers
I have recently gone back to IRC — specifically Freenode — and among the delicious problems of the old days, such as the inability to easily establish DCC transfers (more on that later), I have been presented with the inevitable ident check delay during the connection to server. Ident is essentially a protocol that lets the server…
Headless virtual machines with Oracle VirtualBox
Like any other well-respected geek, I would love to have many computers all around me. However, money constraints make that hard, yet it’s still possible to have extra machines around… if they are virtual. For those unfamiliar with the concept, virtualization is exactly what it sounds like: an entire computer is created in software, possibly…
