bash scripting

I am not a scripting expert, I have to admit that. I am not a sysadmin either. But I think that every developer has to possess wider knowledge about the tools and the platforms he uses.

At least for me, some basic – intermediate knowledge makes me more productive, has saved the day in the past and also makes my life easier.

For example, the power of Linux is that you can write scripts and schedule them with Cron to do a lot of things that is considered to be “dull-programming-stuff”. Let’s start with backups.

Or scheduling automatic backups for things that matter and are also more tricky to perform than simple file backups.

Or also monitoring website up-times and logging the results.

Thoughts on Parallelization

One of these days, as I was revisiting my early high school memories from notebooks, books, love-letters etc, I stumbled upon this simple but also tricky problem:

“One pump can fill up a tank with petrol in 25 minutes.

 Another tank can fill up the same tank with petrol in 15 minutes.

 If we combine both pumps together, how much time is needed for the tank to be filled?”

You can try solving it on your own, before scrolling to the answer. Don’t spoil it so quickly!

“On whether albums in music are dead or not” – English version

The following post is a comment I wrote on a greek blog in response to the following article and also some of the comments that accompany it.

I originally wrote it in Greek, but after some requests, I decided to create an English version too.

I do not agree with the general view and idea that album is dead, without wanting myself to sound like an old man that does not accept the new trends of music industry and is stuck in another age, world.

It was made clear from Tommy in the comments that albums that only existed to serve the title “album” and to fill the package of a 70-80 minutes CD product, will really decline till they finally vanish from the market, because there is no demand for them these days.

This is not something bad.

I disagree with the thought that the artist “must go with the flow of the music business”, especially in our times that each artist can be free from commitments, contracts and pressure from music labels and also I think that

it is really fundamentally expressed and contained in the word “artist” the idea that each artist is free to express, choose, create and follow his own philosophy and way of thinking.

For me,

an album is a live entity, and a real snapshot of a certain time of the artist, it reflects his concerns, mood, inspiration, direction and many other things such as the procedure of composition, creation, as well as the recording and the mixing of an album.

“On whether albums in music are dead or not”

Το παρακάτω κείμενο είναι ένα σχόλιο που έγραψα με αφορμή το παρακάτω άρθρο και κάποια από τα σχόλια που το συνοδεύουν.

Δεν συμφωνώ με τη γενική δαιμονοποίηση του album, χωρίς να θέλω να φανώ οπισθοδρομικός στα καινούρια trends της μουσικής βιομηχανίας.

Όπως έγινε ξεκάθαρο από τον Tommy στα σχόλια, όντως τα album που υπήρχαν σαν albums μόνο και μόνο επειδή το cd χωρούσε 70-80 λεπτά, πρέπει και ΘΑ σταματήσουν τώρα που δεν υπάρχει πια τέτοια ανάγκη.

Γενικά διαφωνώ με την σκέψη ότι “ο καλλιτέχνης πρέπει να πηγαίνει όπως τον πηγαίνουν τα πράγματα” (40 λεπτά βινύλιο – 40 λεπτά μουσική), ειδικά στην εποχή που ο κάθε καλλιτέχνης μπορεί να είναι ανεξαρτητος από εταιρίες κλπ, και εκτός και αν εγώ την παρεξήγησα, νομίζω ότι

είναι “συνταγματικά” αντίθετη με την ελευθερία έκφρασης, επιλογών, φιλοσοφίας και νοοτροπίας, αρχές που αποτελούν το μανιφέστο τη φωνή, αλλά και το λόγο ύπαρξης του καλλιτέχνη.

Για μένα,

το album αποτελεί μία οντότητα, ένα πνευματικό παιδί του καλλιτέχνη, αντικατοπτρίζει τις ανησυχίες του, τη διάθεσή του, την έμπνευσή του, την κατεύθυνσή του και άλλα πολλά, όπως η διαδικασία σύνθεσης, δημιουργίας, ηχογράφησης και μίξης σε μια συγκεκριμένη περίοδο.
