selenium-rc

Posted on May 27, 2010 by margusja

Testin kas selenium-rc server toimib. Enne sisenen serverisse ssh serverinimi -X ehk siis X over ssh.

Valmis ka esimene IPhone simple app

Posted on May 25, 2010 by margusja

Sai katsetatud ka IPhone SDK-d. Iseenesest mõtetu app kuid edev. Kui leian mõne IPhone millega testida siis ehk see osa saab ka arenev.

Minu esimene veebilehitseja

Posted on May 25, 2010 by margusja

Kuna hello world osutus natukene liiga lihtsaks ning tegelikult sai ka teostatud (mõistlik), soovisin teada mida Xcode IDE plus webkit framework koos pakuvad. Olen üllatunud kui lihtne on luua töötavat lahendust.
Siin on minu esimene browser 🙂

Peida-näita apple app

Posted on May 25, 2010 - May 25, 2010 by margusja

Tutvumiseks Xcode IDE-ga on hea treening n.n peida/näita applicationi ehitamine. Annab ülevaate hästi sellest kuidas siduda nupp või nupud eeldefineeritud tegevustega. Või siis kutsume neid build-in tegevustega.
Kokku on lastud app 64 bitise X-code 3.2 peal. OS 10.6.x

Programm lihtsalt peidab ülejäänud aknad vajutades nupule peida ning taastab olukorra kui vajutate nuppu näita.

apache suexec mod_fcgi

Posted on May 19, 2010 by margusja

Juhtus selline asi, et ühe virtualhosti seadistamisel annab error 500 ning logis:

[Wed May 19 11:11:39 2010] [warn] (104)Connection reset by peer: mod_fcgid: read data from fastcgi server error.
[Wed May 19 11:11:39 2010] [error] [client 192.168.0.177] Premature end of script headers: test.php

Ja noh ei saa aru mis viga on.
Lõpuks selgus, et virtuali cgi-bin ning seal asuv wrapper peavad olema 755 õigustes.

Linux LVM/dmraid simple how to

Posted on May 18, 2010 - April 13, 2011 by margusja

 

Esiteks loome lvm manageri jaoks füüsilised kettad.

[root@localhost ~]# pvcreate /dev/sda6 /dev/sdb /dev/sdc /dev/sdd

Physical volume “/dev/sda6” successfully created

Physical volume “/dev/sdb” successfully created

Physical volume “/dev/sdc” successfully created

Physical volume “/dev/sdd” successfully created

Järgmiseks loome volumegrupi:

[root@localhost ~]# vgcreate vg1 /dev/sda6 /dev/sdb Volume group “vg1” successfully created

Viimaks loome loogilise grupi 🙂

[root@localhost ~]# lvcreate –name lv1 –size 500G vg1 Logical volume “lv1” created

Esiteks on tarvis luua dmaraid. Listi kasutatavatest ketastest saab

[root@bacula hpt374]# dmraid -r
/dev/sdd: hpt45x, "hpt45x_cdhfdagge", mirror, ok, 1953525157 sectors, data@ 0
/dev/sdb: hpt45x, "hpt45x_cdhfdagge", mirror, ok, 1953525157 sectors, data@ 0
/dev/sdc: hpt45x, "hpt45x_bhgfhhjhhf", mirror, ok, 1953525157 sectors, data@ 0
/dev/sda: hpt45x, "hpt45x_bhgfhhjhhf", mirror, ok, 1953525157 sectors, data@ 0
[root@bacula hpt374]#

Antud juhul on näha, et kettad tulevad läbi hpt45 driveri. RocketRaid-1640

Juba kasutuses olevad raid-id

Pabetrivaba ARK

Posted on May 17, 2010 by margusja

Väidetavalt on Eesti E-riik. Kunagi ehk oli ka. Hetkel tundub, et me hakkaks nagu kusagilt maha jääma ning igasugused ametid tellivad ja käivitavad oma e-süsteeme ilma neid kontrollimata.
Üks järjekordne näide on paberivaba ARK teiste samalaadsete kõrval nagu Digiretsept.
Igal juhul üritasin ma oma mingit vana auto ajutiselt arvelt maha võtta ja sain sellise täiesti mõttetu veateate millega mul tõesti mitte halligi teha pole. Lisaks veel järjekordne kobaüritus laialt levinud IT väljendit draiver eesti keelde tõlkida. Unzip ütleks selle peale “Tule jumal appi!!!”
