Názory k článku Nová softwarová sklizeň (15. 8. 2007)

June 29th, 2007 vs. 15. august -- v akom predstihu to bolo pisane?

inac to nema chybu

Toto presne si u mna objednal kamos ked mal podozrenie ze ho zena podvadza(nakoniec vraj nie), ved to je tak jednoduche par riadkov to bolo v bash a posielal som obrazky mailom.

Nieco taketo to spravi:
(.jpg je tam koli uspore miesta, pisem aby chytralkovia nepisali ze na screen je best PNG to vieme snad vsetci :) )

#!/bin/bash

#rm obrazok_*
while [ 1 ]; do
subor=obrazok_`date +%Y%m%d-%H%M%S`.jpg
import -quality 80 -window root obrazok_`date +%Y%m%d-%H%M%S`.jpg
echo $subor
# echo | nail -r fero@fero.com -s subject -a $subor mail@mail.com
sleep 2
done

A mate specovaci soft :)

jj a mate podobne hloupy - tedy nesetrny, sw jak uvadene dilko toho autora.

navic nevim ale myslim, ze existuje neco co pouzije napriklad mpeg4 ci flash. kdy je proste prenasena jen zmeny proti puvodnimu obrazku v jpeg + jednou za cas klicovani...

co? nebude to nakonec lepsi :)

o duchovnich otcich nikdo nemluvil...
