Ντεμπούτο για το Direct2D στον Firefox

Η τέταρτη έκδοση beta του Firefox 4 είναι πλέον γεγονός, με το δημοφιλή browser να φέρνει στο προσκήνιο ένα νέο χαρακτηριστικό που αλλάζει τη σχέση του με το hardware. Ο Firefox 4 beta 4 περιλαμβάνει για πρώτη φορά υποστήριξη για Direct2D acceleration στα Windows. Με αυτό τον τρόπο, ο browser αποδεσμεύει τον επεξεργαστή από το rendering των γραφικών, κάτι που αναμένεται να κάνει τη διαφορά στα πολύ "φορτωμένα" sites.


Όπως φαίνεται, οι μηχανικοί του Firefox δεν είναι ακόμη πολύ σίγουροι ότι το Direct2D δουλεύει όπως πρέπει, γι' αυτό κι επέλεξαν να το έχουν απενεργοποιημένο στη βασική εγκατάσταση του Firefox 4 beta 4. Ευτυχώς, πάντως, η ενεργοποίησή του είναι αρκετά εύκολη. Οι ενδιαφερόμενοι χρήστες θα πρέπει να πληκτρολογήσουν about:config στη γραμμή διευθύνσεων, να δώσουν στο mozilla.widget.render-mode την τιμή 6 και στο gfx.font_rendering.directwrite.enabled την τιμή true. Αν η διαδικασία γίνει σωστά, το Direct2D ενεργοποιείται με την επανεκκίνηση του Firefox.

Βέβαια, θα απαιτηθούν πολλές δοκιμές μέχρι να μπει το Direct2D στην τελική έκδοση του Firefox 4. Το μεγάλο στοίχημα είναι να διερευνηθεί η κατανάλωση μνήμης, καθώς και οι αλληλεπιδράσεις με add-ons που έχουν δικό τους σύστημα hardware acceleration, όπως το Flash 10.1.

Copyright enforcement firm ACS:Law hit by embarrassing email leak

It's the weekend and Broadband Genie is enjoying a well-deserved break, but this story was too good to wait until Monday. ACS:Law, the infamous law firm which has been sending out dubious letters threatening to take people to court for file sharing, has had a massive database of its emails leaked onto the web. The ACS:Law web site was taken down by a denial of service (DDoS) attack earlier in the week, an event described by boss Andrew Crossley as "typical rubbish from pirates" . He's likely to have changed his tune now because someone discovered that before the site was restored a backup file containing the emails had been left in an open directory. Inevitably this was downloaded and widely distributed on file sharing networks. The collection includes the incoming and outgoing emails of Andrew Crossley and his employees, complete with attachments, and contains masses of information about how ACS:Law goes about its business and how much money it make
