[This is a repost from my HackTheDay blog of 6 years ago. But these are rare-to-find tips that are still highly valuable.]

You don’t really need a reason to try out these Mac OSX tips and hacks. But they are fun, probably useful and definitely will get a nice reaction from your friends. They all involve typing some commands in the Terminal.app(each command is followed by the Enter key); if commands start with sudo, you might be asked to also type down your Mac administrator password(which you ought to have set when you first logged to your computer). For instructions on finding Terminal.app and tips on using it, see our great Terminal.app tutorial.

According to Goodreads, the most quoted fragment from the best selling book The Alchemist by Paulo Coehlo is:

“And, when you want something, all the universe conspires in helping you to achieve it”

This being the most popular quote is clear proof that people only remember the good and uplifting stories. Also, one of the reasons why “The Alchemist” is dismissed by serious critics who consider it easy reading, a “chicken soup for the soul”-like motivational book.

Way less quoted(80 times less frequently) is this other crucial fragment: (more…)

Once upon a time I owned/wrote a pretty popular website/blog on productivity and lifehacking, which was called Hack The Day  (don’t look for it, it’s been closed down for years and the domain is now owned by scammers). While starting up, I reached out to popular bloggers. That’s how I succeeded in being the first small blogger published by the hottest blog on habit change, productivity and mindfulness of the decade : “Zen Habits” of Leo Babauta.

I wanted to link to it, but Leo has removed all guest posts from those days. So I managed to recover my article from some long-forgotten archive. I’m posting it here, for your enjoyment : the software-related tips might be obsolete, but the general advice retained its value.

It started innocently – a couple of emails on how much stuff costs back there and how tired I was. I wanted to share with my family and friends the novelty of a new country, in a journal-like fashion. But emails felt intrusive given that not everyone on the list cared about the price of yoghurt in the suburb of Paris I had moved in.

This post is not about software or apps. It’s mostly about politics and comment trolls. But there are some generic thoughts which might be useful for others also – hopefully not by inspiring you to troll competing companies or apps.

If you’ve been on the internet for a few years, you must have ran into them. Trolls. Haters. Crazies. Leaving out poisonous comments or reviews, preposterous lies or hidden insults. In my golden years of blogging I sure had my share – fewer since I’ve retired from daily blogging. Some were obvious – people with rude language and opinions. Some were subtle – I don’t even know if they were very weird fans or very subtle haters. Not that it matters, anyway.

This post is dedicated to Tibi, my parent’s godson, who asked me the above question, in a somewhat different form. A bright student now in his 2nd year of high school, he loves computers and sometimes feels that he should be taking advantage more of the opportunities that his generation takes for granted(you know, everyone having computers, internet, access to information). To be honest, his question was actually how can I earn some money after school. I twisted it around trying to cover a more useful area.

Context:
In Mac OSX Lion, I opened Launchboard and deleted an app that I had previously downloaded from the Mac App Store
Problem:
I was no longer able to download it, always getting the same annoying message from the Mac App Store software:
A newer version of this app is already installed on this computer

After spending hours trying to find the fix that does the trick (and, man, did I try them all: removed spotlight indexing from my HDD, removed launchpad db files, removed various folders and files), countless Trash emptied and reboots, I finally found the fix.

Here’s what worked for me (via stackexchange):
I opened up Terminal.app, pasted the line below, then pressed Enter:

/System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -kill -r -domain local -domain system -domain user

A few minutes of waiting, and when it was done I launched the Mac App Store app and.. miracle: I was able to, once again, download my favorite app from the store.

I hope this will save a few hours for you as well

I guess it’s my time again for #idevblogaday. I’ll keep this post short, as I’m still struggling with a bug that prevents me from submitting Clean Writer Pro.

At the beginning of this week I was at Apple’s iOS5 TechTalk in London. It was great. Apart from the rare opportunity of meeting great iOS developers from around the world(I met awesome guys from UK, Vietnam, Germany, Canada, Romania and more), the talks day also brought me a (hopefully long-lasting) inspiration and motivation. In particular, there are three most important things I came back with
