So, you’ve got a friend (or more than one of them) who’s owning a Macbook pro from 2009. Or maybe it’s up to 2012: this article should apply, too. This friend is seriously considering buying a new Mac, because it’s soooo, but soooo, slow - you get the wait icon all the time on the screen, and launching more than one app at a time is an overkill.
Solution? Switch to a faster drive. Currently, the most convenient, and price-worthy option, is the SSD family.
Step 1: buy your SSD drive. (…)

Moving to a new webhosting
16 March 2016, by Valentin MurariuToday I have moved my hosting to a new company.
I hope I did all the correct stuff and I will not get interruptions, especially concerning my emails on my two domains murariu.info and murariu.ch. -
Shell - find files before date
26 October 2013, by Valentin MurariuSo, we have a production system big-bang and I got files produced before and after the big-bang.
How do I find the files produced before the big-bang ? TESTFILE=$(mktemp -u) touch -t 1310122359 $TESTFILE find . ! -newer $TESTFILE rm -rf $TESTFILE
Translation:
– create a temporary file name
– create the file with a timestamp of the big-bang. 1310122359 translates to year 2013 (1310122359), month 10 (1310122359), day 12 (1310122359), hour 23 (1310122359), minute 59 (1310122359)

Where are You ?
14 August 2013, by Valentin MurariuRumi was a 13th century Persian poet. I will not make his biography, that’s why wikipedia is out there for: http://en.wikipedia.org/wiki/Rumi [1]
Rumi, as the wise man he was, gave us this beautiful poem, which I copy on this site as a memory of things I know now, then I tend to forget:
Allah
I tried to find Him on the Christian cross, but He
was not there; I went to the Temple of the
Hindus and to the old pagodas, but I could not
find a trace of Him anywhere.
I searched on the (…) -
Nice badminton rallies
14 August 2013, by Valentin MurariuDiscovered in the French edition of 20min.ch: http://www.20min.ch/ro/sports/autres/story/Le-plus-long-point-de-l-histoire-12818886
Then, should you have sleeping problems, you can always watch this, and count the shots. You should fall asleep within the first minute: http://www.youtube.com/watch?v=slhgU_ATNjg
I like badminton, but I clearly do not play at this level. My rallies are much, very much, shorter. -
It’s a dangerous world !
13 August 2013, by Valentin MurariuIt is dangerous out there, didn’t you know ? Asteroids all over the place. And, again, some news about how Jupiter helps us (or not):
An interesting point about the orbits is how so many of them are tucked inside the orbit of Jupiter, with only a few shooting beyond to the outer Solar System. That makes Jupiter a bit of a two-faced friend. On the one hand, having a giant planet in the neighborhood is great because in the early days of the Solar System it swept up all the cosmic debris that (…) -
Vibrations in the real world
2 July 2013, by Valentin MurariuOf course, you don’t believe in all the new age stuff with vibrations and all, don’t you ?
So, let’s introduce you to the visible part of it: Exhibit #1: water and sound experiment:
https://www.youtube.com/watch?v=uENITui5_jU
What is nice, is that you can build it yourself (almost easily):
– a speaker
– a water hose connected to a water supply
– tone generating equipment
– a 24 frames-per-second camera Exhibit #2: the resonance experiment
This one starts with a quote from Nikola (…) -
Mighty alcohol
2 July 2013, by Valentin MurariuSo, my friends, as human knowledge gets more diversified, the guys at Discovery News tell us that alcohol can be/is created into deep space, where the temperature comes close to absolute zero. How that can happen ? The smart guys tell us: Through a quirk of quantum physics, it’s possible for two particles to overcome the electrostatic barrier. The quantum “wave-like” nature of particles allows a small probability that “quantum tunneling” may occur through the electrostatic barrier, an (…)

Silence
15 April 2013, by Valentin MurariuI am reading Peter Høeg’s fiction "The Quiet Girl" (Den stille pige), 2006. The book is a thriller, and ... no, I am not going to you tell the story.
The point is that the book mentions every now and then the "silence": as I read it in French, and the quotes are from the book, here you have some pieces:
...J’ai cherché ce silence-là toute ma vie... Et si tu mettais de boules de Quiès ? Il y aurait encore du bruit. Le bruit du corps... mes propres pensées. Le silence que je cherche est (…)
