everywhere internet

long time ago, bout 12 or 13 years ago, i never dreamed to have this blog. Not even blogging, i even never dreamed that i could access internet from my mobile phone.

It was when i were in 1st grad of my junior high. I had my first experience in exploring the internet world. That time, the only way i knew to access the internet was only with phone. Not mobile phone, but phone for your home. Using phone cable, and using your computer. Mobile phone? Yes, you could have internet access from your mobile phone. But at that time, there were no colour mobile phone just like today. Who would like to accessing internet with only seeing 2 colours,black and yellow, or black and green, at your screen?

So, at my first atempt to connect my self to the world to the internet, it was need loooot of guts to do it. Why? B’cos, you know, there were not much internet service provider that time. So i had to brace my self to ask my parents to access the internet with the only way i knew that time, using telkomnet instant. If you compare it with any other internet service provider you know now, then telkomnet instant was ten times worse then the slowest speed of ISP you know. The maximum speed was only 56 Kbps, and it mean only 7 KBps!! And it is the max speed, or in comercial advertise words, only UP TO 56 kbps! Up To! Man.. Can you imagine how slow it is? Beside that slowness, telkomnet instant was also expensive. Rp 150 per minute. It mean, Rp 9000 per hour. Slow, and expensive. What coud have been worse?

But well, b’cos of my curiousity (with my brother too actually), we kept to try to connect ourself to the internet. That time, we only have a Pentium III PC. Not so fast even you compare it with your laptop i’m sure. So we dragged the computer table with the computer on it to reach the phone cable. We plugged the cale to the computer, do some setting according to the advertising that we saw. Clicked here, clicked there, for the first attempt we were failed. We coldnt connect to the internet. Aaaah…we were so disappointed that time… We had dragged that heavy computer table, but we still couldn’t connect our self to the world using internet…

But then, we tried again the next day. With previously read about how the computer setting should be, we braced ourself again and tried to connect to the internet again. The cable was plugged, the setting was done, and then we clikced the Internet Explorer icon. I remembered the first page that we tried to open was telkom’s site. It was such a loooong waiting to open that page…. May be as long as my time to graduate from my college. Hehe..
But you know what? When we saw the loading bar, it showed some progress! There’s a sign that we were loading that page n it mean we were connected to the internet! Yeay! We made it! So we waited till the page was fully loaded. Me, i was soo exited to know what the page look like, moreover, what was the internet world look like. when the page was fully loaded, whoaaaa…. I was sooo amazed… Lot of pictures i saw….not only pictures, but also animations. ‘i made it….’ i said in my heart. ‘oyeah….cool!’

But then that page was the only internet page were opened by my computer. B’cos that time, loading one page needs minutes to open it. Damn… So long and so expensive. So my parent told me to go to the internet cafe if i want to surf the internet world again.

it was such a great beautiful experience, you know. Knowing that nowdays people can access the internet anywhere and anytime they want with low price. Even we can bring the internet with our hands! Just like right now, i’m blogging with my mobile phone. But in the past, i had to dragged my computer table, plug the wire to a computer, wait for a long time toload a page, had to pay much for internet access.

Yes the technology is growing fast. If now you can have a PC on your palm, what next could be? A PC in our sun glasses? Or maybe implanted in our body? Who knows?
Something sure, use anykind of technology wisely

benerin pesen eror “E: Could not get lock /var/lib/apt/lists/lock ”

sedikit berbagi ilmu..
bermula dari gw yang g bisa menjalankan perintah apt-get update, gw browsing2 di internet, n akhirnya dapet solusinya.

ini cerita lengkapnya:

awalnya gw mw install wammu n gammu di ubuntu gw. pake nambahin keyring dr terminal. cuma di tengah prosesnya, ternyata penambahan keyring itu gagal. gw coba ke langkah selanjutnya, yaitu mengupdate database repositori, gak bisa juga. tapi kl gw coba apt-get install wammu, itu masih bisa. well, gw pikir g ada apa-apa.
sampe akhirnya, pas ada update notification, pengen gw update sistem, eh, mentok..

akhirnya gw jalanin lagi apt-get update dari terminal, muncul pesen eror yang kira-kira kayak gini:

debian:~# apt-get update
E: Could not get lock /var/lib/apt/lists/lock – open (11: Resource temporarily unavailable)
E: Unable to lock the list directory

gugling, cari sana cari sini, baca baca, dapet juga solusinya dari sini.

cuma butuh dua langkah.
pertama, jalanin perintah ini:

debian:~# killall -9 apt-get aptitude

itu buat matiin semua proses yang berhubungan sama perintah apt-get. mungkin langkah ini dibutuhin, mungkin juga enggak.

kedua, jalanin perintah ini:

debian:~# rm -f /var/lib/apt/lists/lock

nah, kalo udah jalanin perintah itu, tokcer dah. urusan apdet mengapdet bakal lantjar djaja. apt-get update bisa dijalanin, n update sistem dari update manager bisa dijalanin lagi.
ohya, jangan lupa jalanin semua perintah diatas pake sudo atw user root.

semoga bermanfaat.

beberapa langkah yang sebaiknya dilakukan setelah install ubuntu (2)

yak, setelah posting pertama, yaitu tentang merubah sumber repositori on line, langkah berikut yang akan saya lakukan setelah saya menginstall ubuntu adalah menginstall codec untuk multimedia.

codec sendiri adalah sebuah program yang berfungsi untuk meng-enkode dan atau meng-dekode sinyal atau aliran data digital (codec menurut bang wiki). ribet ye? yah intinya mah, suatu program tambahan yang berfungsi untuk memutar file multimedia kayak .mp3, .mp4, .flv, .mkv, dll. poqoknya semua yang berbau multimedia.

ubuntu secara default tidak menyertakan codec multimedia ini. kalo menurut penjelasan di sini dan di sini, codec-codec multimedia itu mempunyai batasan paten dan hak cipta di beberapa negara. batasan hak cipta dan paten itu yang membuat ubuntu tidak menyertakan codec multimedia pada paketnya, karena bertentangan dengan prinsip Ubuntu yang berkomitmen untuk menyertakan paket/program yang benar-benar gratis di negara manapun. jadi, kalo menginstall Ubuntu yang asli (bukan turunan-turunannya kayak SuperOS atau BlankOn atau apapun), codec untuk memainkan file multimedia itu harus diinstal sendiri oleh pengguna.

beberapa langkah yang sebaiknya dilakukan setelah install ubuntu (1)

bermula dari gw yang downgrade ubuntu gw dari versi 11.04 ke 10.10, yang itu juga berarti gw harus install ulang smw program yang udah gw install di Linux+berarti gw jg harus meng-install ulang beberapa modofikasi desktop gw. (walau cuma dikit sih)

sedikit tutorial, sekaligus biar gw gak lupa apa aja yang harus gw install, ini beberapa hal yg gw lakukan setelah gw install ubuntu. lengkap dengan gambar n berbahasa indonesia n sedikit menggunakan terminal.

enjoy.

yang pertama gw install adalah mengubah sumber software (software source). ketika ubuntu akan menginstall suatu program, entah itu lewat ubuntu software center atw lewat perintah apt-get, maka sistem akan membaca database program lewat internet. sebut saja database ini disebut repositori (repository). nah, awalnya, sistem menggunakan repositori yang servernya ada di amerika sana. jauh, dong? apa lagi bagi pengguna internet yang kecepatannya lemot bin lambat. nah, karena itu, sebelum memulai install semua program, gw mengubah sumber software-nya agar sistem mengecek repositori pada server yang berada di Indonesia. biar lebih cepet, gan!
ini caranya:

pertama, buka

System > Administration > Update Manager

Magic SysRq key

The magic SysRq key is a key combination understood by the Linux kernel, which allows the user to perform various low level commands regardless of the system’s state. It is often used to recover from freezes, or to reboot a computer without corrupting the filesystem.

To be able to use this functionality the CONFIG_MAGIC_SYSRQ option has to be enabled at kernel compile time.

Purpose

Much like Sun Microsystems’s Open Firmware (OpenBoot), this key combination provides access to powerful tools for software development and disaster recovery. In this sense, it can be considered a form of escape sequence. Principal among the offered commands are means to forcibly unmount file systems, kill processes, recover keyboard state, and write unwritten data to disk. With respect to these tasks, this feature serves as a tool of last resort.
