10 Bencana Terbesar Karena Kesalahan Software
1. Roket Mariner I (1962)
Roket ini keluar dari jalur peluncuran dan hancur.
Penyebab: programmer lupa menuliskan kode overbar.
2. Satelit Eole I (1971)
Satelit milik Prancis ini jatuh dengan membawa 72 balon cuaca.Penyebab: permintaan untuk mengirim data pengukuran diterjemahkan keliru oleh software sebagai perintah self-destroy.
3. Satelit Nimbus 7 (1978)
Satelit ini mengabaikan lubang ozon di atas Antartika.
Penyebab: software analisis menganggap nilai yang tidak lazim sebagai kesalahan dalam pengukuran dan kemudian mengoreksinya.
4. Reaktor Atom (1979)
Lima reaktor atom Amerika tidak berfungsi karena software memberikan nilai yang keliru untuk pengukuran kekuatan gempa bumi.
Penyebab: program melakukan penjumlahan yang seharusnya menghitung akar dari jumlah kuadrat.
5. Perang Dunia Ketiga (1983)
Sebuah satelit Sovyet melaporkan adanya lima roket inter kontinental. Kolonel Petrow kemudian melihatnya sebagai ancaman walau ternyata keliru.
Penyebab: software mengartikan pantulan cahaya sebagai roket musuh.
6. Therac 25 (1985-1987)
Alat rontgen menewaskan banyak pasien akibat dosis sinar yang berlebihan.
Penyebab: software hanya dapat melakukan beberapa tugas sekaligus dengan baik apabila pengguna memberikan perintah secara perlahan.
7. Wallstreet (1987)
Bursa jatuh menimbulkan kerugian harian sebesar 22,6 % atau 500 milliar dollar.
Penyebab: software bursa tidak cukup cepat memproses order pembeli saham. Akibatnya terjadi kepanikan dalam transaksi.
8. USS Vincennes (1988)
Kapal perang AS ini menembak sebuah pesawat penumpang Airbus milik Iran, 290 penumpang tewas.
Penyebab: sistem “Aegis” seharga 400 juta dollar melaporkan Airbus tersebut sebagai “assumed hostile”. Para crew kemudian menduga ada serangan pesawat tempur.
9. AT & T (1990)
Software telepon baru memaksa semua sentral swithching masuk ke dalam reset mode secara berantai. Oleh karena itu, telepon tidak dapat digunakan selama sembilan jam.
Penyebab: keliru menggunakan perintah “break”.
10. Ariane 5 (1996)
Roket ini keluar dari jalur dan meledak.
Penyebab: overflow saat mengonversi sebuah nilai floating 64 bit dalam software “Ariane 4″.

November Rain by GN'R (Lirik)
When I look into your eyes
I can see a love restrained
But darlin' when I hold you
Don't you know I feel the same
'Cause nothin' lasts forever
And we both know hearts can change
And it's hard to hold a candle
In the cold November rain
We've been through this such a long long time
Just tryin' to kill the pain
But lovers always come and lovers always go
An no one's really sure who's lettin' go today
Walking away
If we could take the time to lay it on the line
I could rest my head
Just knowin' that you were mine
All mine
So if you want to love me
then darlin' don't refrain
Or I'll just end up walkin'
In the cold November rain
Do you need some time...on your own
Do you need some time...all alone
Everybody needs some time...on their own
Don't you know you need some time...all alone
I know it's hard to keep an open heart
When even friends seem out to harm you
But if you could heal a broken heart
Wouldn't time be out to charm you
Sometimes I need some time...on my
own Sometimes I need some time...all alone
Everybody needs some time...on their own
Don't you know you need some time...all alone
And when your fears subside
And shadows still remain, ohhh yeahhh
I know that you can love me
When there's no one left to blame
So never mind the darkness
We still can find a way
'Cause nothin' lasts forever
Even cold November rain
Don't ya think that you need somebody
Don't ya think that you need someone
Everybody needs somebody
You're not the only one
You're not the only one
