Salah satu cara untuk mengatasi hal tersebut adalah dengan menon-aktifkan fungsi permalink untuk sementara melalui database supaya dapat login kembali dan melakukan pengaturan ulang permalinknya.

Berikut adalah query yang perlu dieksekusi melalui database console atau phpMyAdmin

-- kosongkan opsi permalink_structure dari table wp_options
UPDATE wp_options SET option_value='' WHERE
option_name='permalink_structure';

-- kosongkan opsi rewrite_rules dari table wp_options
UPDATE wp_options SET option_value='' WHERE
option_name='rewrite_rules';

setelah menjalankan perintah sql tersebut, wordpress sudah bisa diakses kembali seperti sebelumnya, tanpa permalink.

force reboot your machine, just like “press the reset button”

$ echo 1 > /proc/sys/kernel/sysrq
$ echo b > /proc/sysrq-trigger

if you want to force shutdown machine, just like “press the power button”

$ echo 1 > /proc/sys/kernel/sysrq
$ echo o > /proc/sysrq-trigger

the script will bypass disc syncing, close application, daemon, etc. during regular reboot/shutdown process.
you will find this script useful when the machine is not responding, and you still have SSH session.

here is original nice bash commands for exporting updated files between 2 revision from svn repository
found from  interspire developer network
for i in $(svn diff --summarize -r 1403:1438 http://server/svn/project/trunk |
awk '{ print $2 }'); do p=$(echo $i | sed -e 's{http://server/svn/project/trunk/{{');
mkdir -p $(dirname $p); svn export $i $p; done

and i made bash script to to simplify this task

#!/bin/bash
EXPECTED_ARGS=2
E_BADARGS=65
#check at leat given 2 paremeters, url and revision number
if [ $# -ne $EXPECTED_ARGS ]
then
echo "Usage: `basename $0` {repo_url} {rev1} [rev2]"
exit $E_BADARGS
fi
REPO=$1
# ask for svn username and password
echo -e "enter your svn username: \c"
read USER
echo -e "enter your svn password: \c"
read PASS
#get latest revision number if no third parameter given
if [ -n "$3" ]; then
REV=$2":"$3
else
REV=$2":"$(svn info --username $USER --password $PASS -r HEAD $REPO | grep Revision: | cut -c11-)
fi
echo "exporting update $REV from $REPO\n"
#do the job to export the updated files to update-$rev1-$rev2 directory
for i in $(svn diff --summarize --username $USER --password $PASS -r $REV $REPO |
awk '{ print $2 }'); do p=$(echo $i | sed -e 's{'$REPO'/{{');
p="update-"${REV/:/-}"/"$p
mkdir -p $(dirname $p); svn export --username $USER --password $PASS $i $p; done

But what if it’s a raw post with only the post body and no key? Such as an xml api post?
Simple: use “php://input” as a text stream and read it with functions such as file_get_contents.

today i was surprised with the new delicious.com feature.
you can now directly share your bookmarks on delicious to your
delicious network,  your friends email and the long awaited feature is the ability directly to post your bookmarks to twitter. even better, it come with built in short url feature!

before, we must create an account and a feeder on www.twitterfeed.com to post our delicious bookmarks to twitter.

to integrate our twitter account is pretty straight forward, just enter your twitter username and password on the “SEND” tab, and done! your twitter account is connected to your bookmarks.

thanks to delicious team, keep up the good works mate!

# find . -name .svn -print0 | xargs -0 rm -rf

the command will scan the directory for .svn folder and delete them.

you can also get a clean copy of your files by exporting files from your repository.

>cd working/copy/of/branch
>svn diff -r 3198:3199 >r3199.diff

if you want to create patch as unified diff format, use this command

> svn diff –diff-cmd /usr/bin/diff -x “-ua ” -r3198:3199 > r3199.diff

Apply the patch to a working-copy of the trunk:

>cd working/copy/of/trunk/bro
>patch -p0 -b -B ./backup/ <r3199.diff

When something wrong happened, and you want to restore your working copy to original version (before applying the patch), you can invoke command:

> cd working/copy/of/trunk/bro
> patch -p0 -R < r3199.diff
