If you need memory, use midori. Not firefox, Not Chrome!
Posted by ebal at 08:44:46 in planet_ellak, planet_Sysadmin

The picture speaks for it self.

web_browsers.png

Same tabs - same sites - same resources - same time - same logins.

Firefox is just a memory leak before it crash your linux box! But it is the most extensible browser. You can do almost everything via Addons.

Chrome is the middle & safe solution but i cant use xmarks with a custom server and i cant use different proxies with exclusions but only shell variables (http_proxy).

Midori has the same engine as chrome (webkit, same restrictions as Chrome. Isnt extensible as chrome but uses UserScripts & UserStyles

But midori uses the least memory, its super fast and perfect for your simple needs.

My opinion is NOT to use only one web browser, but choose the browser by the need you want to cover.

hackfest3: live by the code
Posted by ebal at 08:46:01 in planet_ellak

Όπως ήδη γνωρίζεται ΟΛΟΙ (όσοι τουλάχιστον είναι σε αυτόν τον γαλαξία) ότι αυτή την Κυριακή, 23 Ιανουαρίου 2011, θα πραγματοποιηθεί το 1ο hackfest για το 2011.

Το hackfest είναι ένα event - μία συνάντηση, στην οποία όσοι ασχολούμαστε με το opensource βρισκόμαστε για να ανταλλάξουμε ιδέες, να συζητήσουμε για τα projects που μας απασχολούν κατά τον ελεύθερο χρόνο μας και μη.

Αυτή την Κυριακή, όμως θα υπάρχει θεματική ενότητα!

Κι αυτή δεν θα είναι άλλη από την fosdem.
Η fosdem είναι η μεγαλύτερη ευρωπαϊκή συνάντηση opensource developers!
Γίνεται πάντα το 1ο Σαββατοκυριακο του Φλεβάρη στις Βρυξέλλες (Βέλγιο).

Ελπίζουμε να έρθουν οι “νέοι” και οι “παλιοί” συμμετέχοντες για να συζητήσουμε/ανταλλάξουμε εμπειρίες/ενημερώσουμε ο ένας τον άλλο για τα DOs & DON’Ts.

Θα είναι πολύ ενδιαφέρον … οπότε σας περιμένουμε.

Καφεδάκι, μπύρα, τσάι, τοστ ΟΛΑ τα πληρώνεται από την τσέπη σας!
Τα νερά όμως είναι ΔΙΚΑ μας, ναι, ναι σωστά διαβάσατε, τα νερά κερασμένα από εμάς.

Ραντεβού λοιπόν στην καφετέρια Floral (Θεμιστοκλέους 80, Πλατεία Εξαρχείων)
από τις 11.00 και μετά και για περίπου 4 ώρες, ελάτε να συζητήσουμε και να δουλέψουμε για opensource & fosdem.

Παράλληλα θα περάσω το latest stable Xfce 4.8 στο laptop μου για όποιον ενδιαφέρεται να δει πως είναι!

ziproxy & privoxy aka fasten your seatbelts
Posted by ebal at 11:56:33 in planet_ellak, planet_Sysadmin

hackfest is mainly for sharing opensource ideas. One of this was suggested to me by comzeradd. He told me that he is using ziproxy to compress data through his phone (story here android-ziproxy).

So i am using ziproxy from October 2010, to compress all my internet traffic.

Another proxy i am using (mostly for the chain forward ability) is privoxy. Privoxy can forward traffic through another proxy (http or a socks) but has filtering features too. Privoxy can block ads & flash on the spot. It is a well known opensource proxy to system administrators too, who they use it to bypass firewalls or dmz or complex networks.

I believe that everyone who respect his self has No Script, Ad Block Plus with kargig’s filter Greek Ad Block Plus Filter and Flash Block enabled on his/her browser.

All the above add-ons block Js, Flash & Ads on client browser. That means that already you have download them.

If you need to reduce http traffic the solution is to combine ziproxy and privoxy!

By the way, it’s extremely easy, so you should give it a try.

You simple install privoxy and run it locally and then open ziproxy.conf to add these:

NextProxy=”127.0.0.1”
NextPort=8118

Run ziproxy as normal and voila !

Some benchmarks to show you the truth:

wget -d -p www.otenet.gr/otenet/ –no-proxy –no-cache

No Proxy:

Downloaded: 73 files, 718K

Ziproxy:

Downloaded: 73 files, 479K

Ziproxy - Privoxy:

Downloaded: 70 files, 475K

Another on:
wget -d -p http://www.villagecinemas.gr/

No Proxy:

Downloaded: 92 files, 1,1M

Ziproxy:

Downloaded: 92 files, 527K

Ziproxy - Privoxy:

Downloaded: 80 files, 160K
