Joomla Content Syncronisation - Joomla! Forum - community, help and support

hi guys, i'm looking easy way synchronize content (or changed since initial install - except components & modules loaded - if understand mean) of same version joomla installations. i have joomla 1.0.8 installed on local laptop , installed on webserver. when cannot on-line, continue modify , make changes joomla on laptop. when on-line, need either replicate did offline manually, or export db flat file , upload on-line db. i know of no other ways of "sync-ing" changed content on joomla. there way? now programming skills scary least, seems cannot difficult code. should simple sql export on 1 side , authenticate and  import on other side. correct? now exclude components, modules , templates. should same. if make happen, i'm sure there huge amount of joomla users , use it. thanks excellent product , keep work!!!!!!!! your best! sias berg you seen http://dev.joomla.org/component/option, ... d,33/p,71/ ?

[solved]1-Wire Temperature Sensor - Genauigkeit?

hallo, ich möchte bei unserem pool, welcher von einer wärmepumpe erhitzt wird, die temperatursteigerung nachverfolgen. die temperatur steigt - rechnerisch - in ungefähr 3 1/4 stunden um 1°c. ich möchte ca. alle 20 min eine messung machen. aus diesem grund brauche ich einen ziemlich genauen temperatursensor, 1-wire würde ich bevorzugen. gibt es die mit 0,1°c auflösung? ich habe außerdem gelesen, dass die meisten eine genauigkeit von +-0,5°c haben. ist das die genauigkeit über die ganze verfügbare temperaturspanne oder die genauigkeit für einzelmessungen? (wäre natürlich ungünstig wenn meine messungen stark schwanken, bei denen sich um 0,1°c ändert plötzlich solche ausreißer hätten) gruß kduin [font=verdana]edit: habe jetzt die sensoren (ds18b20) testen können. die temperatur ist zwischen mehreren messungen absolut stabil.[/font] sensoren mit der geforderten genauigkeit wird man vermutlich nur in der professionellen messtechnik finden. günstig sind diese si...

Serveur web "proxy" vers LAN - Raspberry Pi Forums

salut, novice en développement web, je vous soumet une question : j'ai chez moi plusieurs équipements administrables via interface web (switch, routeur, webcam....) pour accéder à tout ce petit monde depuis l'extérieur, j'ai naté autant de ports que de serveurs web... ma question : est-il possible d'accéder aux interfaces web de mes équipements depuis une seule url, en intégrant/mappant les pages web d'admin dans un seul site, hébergé sur le raspi ? en d'autres termes, utiliser le serveur web du pi comme un "proxy" vers les serveurs web du lan.... (et ainsi éviter le mode gruyère sur le routeur avec 2 ports ouverts par équipement: un pour l'admin, un pour le service) merci ! pour ça, selon moi, le plus simple c'est un tunnel ssh. un seul port à mapper, le 22 (ou le 443) depuis n'importe où, tu lances putty, tu te connecte à ton raspberry en ssh. tu connectes ton navigateur à putty qui servira de proxy socks. via ton naviga...

Request to Dom - more info on firmware commits - Raspberry Pi Forums

hi dom, firstly, work you're doing pi hackers. i've noticed (if not all) of firmware commits seem in response bug reports/feature requests made in various places around internet - these forums, github issue tracker, elsewhere (xbmc forums?), there more discussion or info particular commit doing/fixing. ask when case, put link these discussions in commit messages, make easier know what's going on firmware? these commits make lot more sense when context known. e.g. last commit dispmanx_snapshot() described in more detail in post , thread gives background why done: http://www.raspberrypi.org/phpbb3/viewt ... 38#p380938 people following commit messages on github wouldn't have clue that. thanks. can pm him in case doesn't see post? raspberrypi
