korki’s corner

its not more than a week that i got a twitter acct. So if you are intrested in the micro equivalent of my blog then by all means visit me @ http://twitter.com/korkakak

It nearly two months since I last wrote anything in my space (this one i mean :P), so I guess it’s time to update the few fellas that follow me electronically.

Not long ago, i was introduced into indifex, a company specializing into scalable content distribution technologies. I joined that fellowship and currently I am intrigued by its merits. First of all I got acquainted with django [1] which is a web design/implementation framework written in python. I really like python so this is, in principle, cool!

In the past few weeks every day is a new challenge workingwith something unique and ultra nice. For instance in the previous week I got involved with rabbitmq[2] and celery[3]. Rabbitmq is a distributed queueing system implementing AMQP protocol [4] (other cool servers are zeromq[5] - a really good comparison based on hard facts among them can be found here [6]) Celery on the other hand is a distributed task queue, designed -at first- for django projects. It is used for executing tasks asynchronously, routed to one or more worker servers on the same or distinct machine(s), running concurrently using multiprocessing on each one of them.

Another challenging task I faced was the overall design of the web services of transifex.net, using bleeding edge performance targeting applications like haproxy[7], nginx[8]. On this design many questions and objections were raised against the proposed design, but after all the architectural superiority prevailed and stayed.

Soon I will update with  the cloud (amazon ec2 and rackspace cloud) experience

Το ξέρω οτι είπα το δεν θα ξαναγράψω κάτι αλλά σήμερα έτυχε και δίαβασα στο site του κυβερνητικού οργανισμού ΕΡΤ για την εξέλιξη της νόσου. Φυσικά η οποια αρρώστια είναι κάτι το λυπηρό,  αλλά με αυτά που διάβασα στο εν λόγω άρθρο γέλασα αρκετά. Μάλλον θυμίζει ολίγον τί σκηνή από αμερικάνικη comedy που ο πρωταγωνιστής για να προκαλέσει το γέλιο περνάει μια χιονοστοιβάδα προβλημάτων μόνο και μόνο για την τέρψη του θεατή (και της τσέπης του φυσικά).

Δεν ξέρω ποιος ήταν/είναι ο σκοποςτου συγγραφέα του άρθρου (αν ήταν χιουμοριστικός ή άλλος) αλλά σε κάθε περίπτωση 

Της εύχομαι ειλικρινά και ολόψυχα καλή ανάρωση

It’s been a while since I wrote something in this blog, I know, but I am coping to finish my M.Sc. diploma thesis so, it gonna be a while until the next time. So far there are 11-12 articles unpublished semi-finished about various issues hell I even wrote about the new acropolis museum but still

I ll be back (soon I hope)

PS I exceeded 170pages in my thesis and still have an enormous amount of topics to cover 

This is a quick blog post in order to set things straight. Though all major results from google pointing to the contrary (that linux is uninstallable on a sparc machine) these days I came to a fully functional 480 server while using gentoo sparc autobuilds. Other linux distros (debian,redhat,centos,suse) could not even boot the machine :S

So gentoo is your friend.

If for any reason anyone is intrested on the specifics of the “operation” please write a follow up

Αυτή η εβδομάδα (μάλλον το τέλος της προηγουμενης μέχρι την δευτερα) βγήκα και πήγα σε πολλά public events, και στα οποια θα ήθελα να αναφερθώ σε επόμενα posts.

• Escape Lanparty
• Artware festival
• Η ΚΙΝΗΣΗ ΠΟΛΙΤΩΝ ΠΑΤΡΑΣ ΕΝΑΝΤΙΑ ΣΤΙΣ ΚΕΡΑΙΕΣ ΚΙΝΗΤΗΣ ΤΗΛΕΦΩΝΙΑΣ

Στα επόμενα post θα αναφερθώ μερικώς η διεξοδικά στα παραπάνω events

All the good stuff in upatras happen by individuals offering services and organizing events on their own. In the upcoming weekend 22-23-24 / 5 /2009 two major events will take place in the upatras campus.

First and most important is the Escape Lanparty v5.2 [1] . Although this is an event for geeks and hardcore gamers, it seems , that it will draw a lot of attention over the student corpus. Many PWMN members will join the party as well (estimated numbers are 20-25 people of the pwmn community attending of the 200 available seats so this will be at least 10% of the attendants) Prepare your shares This event will take place on the students dormitories hall[2] so be prepared to rock.

The second event is the artware[3], a mixture of artistic creation on various fields i.e. music, drawing, etc and will take place [4] in the computer engineering department.

I hopefully will attend both in a time sharing basis, so I will keep you informed. Of course you can get informed yourself by attending either or both of the events.

Cheers

Η ιστορία επαναλαμβάνεται, σε άλλο πεδίο. Δεν θέλω να εκφράζω συναισθήματα και λέξεις για τους καραγκίοζηδες που επιλέγουν κρατικοδίαιτους τραγουδιστέ/αστέρες και όλο το συναφές στερέωμα PUBLIC RELATIONSHIPS και δεν συμαζεύεται από τα γαμμημένα τα χρήματα που με αναγκάζουν να πληρώνω κάθε μήνα στην κωλοΕΡΤ μέσω της κωλοΔΕΗ.

Για αυτό που λυπάμαι είναι οτι με τα ίδια χρήματα 1000-1500 άνθρωποι θα είχαν μια υποτροφία για να συνεχίσουν τις σπουδές για 2-3 χρόνια τους και να προάγουν τον πολιτισμό όχι της μορφής του κιτς πανηγυριού της φιέστας των κουφιων lifestyle symbols αλλά στο πεδίο της έρευνας και της ανάπτυξης πολλών και διαφορετικών επιστημονικών πεδίων

ΠΡΕΠΕΙ ΝΑ ΑΝΤΙΤΑΧΘΟΥΜΕ ΣΤΗΝ ΜΑΛΑΚΙΑ ΚΑΙ ΤΗΝ ΣΑΠΙΛΑ ΤΩΝ LIFESTYLE SYMBOLS.

ΑΜΦΙΣΒΗΤΗΣΗ, ΑΠΕΙΘΕΙΑ, ΑΝΥΠΑΚΟΗ - ΚΛΕΙΣΤΕ ΟΛΟΙ ΤΗΝ TV

Το LifeStyle ειναι μαγικό γιατί μετατρέπει τα μηδενικά σε νούμερα…

ΥΓ το τραγούδι για το EURO έχει αρκετές ομοιότητες με την ελληνική συμμετοχή στην σκατό EUROVISION, μπορείτε να τις βρείτε;

as promised and within the 16hours deadline the kOlga is back online. The new feature set installation (hotspot, gardenwall, red queueing on all interfaces, etc) is postoponed for the future.

Enjoy the beautiful saturday and the weekend

PS1. The tzikis link was decommissioned due to poor performance (4mbps up 4mbps down) but may be brought back if noone else provides a link for him.

PS2. To the guy that broadcasts in southwest patra region with mac address : 00:0B:6B:09:F2:7E and hidden SSID @ 5180Mhz please contact me if you interested for a link. My scans indicate a very good signal from your side (-55dbi with SNR of 50db)

configure: Using system-installed FFMpeg code
configure: WARNING:
======================================================================
WARNING: you have chosen to build gst-ffmpeg against a random
external version of ffmpeg instead of building it against the tested
internal ffmpeg snapshot that is included with gst-ffmpeg.

This is a very bad idea. So bad in fact that words cannot express
just how bad it is. Suffice to say that it is BAD.

The GStreamer developers cannot and will not support a gst-ffmpeg
built this way. Any bug reports that indicate there is an external
version of ffmpeg involved will be closed immediately without further
investigation.

The reason such a setup can't be supported is that the ffmpeg API
and ABI is in constant flux, yet there aren't any official releases
of the ffmpeg library to develop against. This makes it impossible
to guarantee that gst-ffmpeg will work reliably, or even compile,
with a randomly picked version ffmpeg. Even if gst-ffmpeg compiles
and superficially appears to work fine against your chosen external
ffmpeg version, that might just not be the case on other systems, or
even the same system at a later time, or when using decoders,
encoders, demuxers or muxers that have not been tested.

Please do not create or distribute binary packages of gst-ffmpeg
that link against an external ffmpeg. Thank you!

LOL that’s what I call programmers with humor And of course build succeeds and ffmpeg packages works alright
