Pas booting muncul error cannot mount /dev on /root/dev bla bla, kemudian masuk console BusyBox

Googling dan nemu solusi di ubuntuforum (lupa link-nya), mari kita coba

booting pake livecd (untungnya punya livecd)
buka terminal ketikan

$ sudo e2fsck -p -y -f /dev/sda2

sda2 diganti dengan dengan partisi hardisk anda

restart kompi dan alhamdulillah bisa booting lagi.

Ternyata masih ada masalah lagi, lihat network icon, lho kok network function disabled.

masuk terminal

~$ sudo lshw -C network

Keluarin jurus andalan *Googling*, mecoba solusi berikut

~$ sudo pico /var/lib/NetworkManager/NetworkManager.state

ternyata nilai untuk NetworkingEnabled=false, ganti nilainya jadi true, simpan kemudian jalankan network manager

~$ sudo service network-manager restart

MongoDB merupakan salah satu dari beberapa noSQL database. Menurut situs nosql-databases.org definisi nosql adalah sebagai berikut.

NoSQL DEFINITION: Next Generation Databases mostly addressing some of the points: being non-relational, distributed, open-source and horizontal scalable. The original intention has been modern web-scale databases. The movement began early 2009 and is growing rapidly. Often more characteristics apply as: schema-free, easy replication support, simple API, eventually consistent / BASE (not ACID), and more. So the misleading term "nosql" (the community now translates it mostly with "not only sql") should be seen as an alias to something like the definition above.

Terus terang saya sendiri masih bingung tentang noSQL database ini, karena saya juga baru ngerti kalo ada yang namanya noSQL. Setelah googling kesana kemari, akhirnya ada sedikit pencerahan walaupun tetep masih bingung . Untuk mengobati rasa penasaran akhirnya saya coba menginstall salah satu noSQL database yaitu MongoDB pada laptop saya yang berOS Ubuntu. Cara Menginstallnya adalah sebagai berikut. Read more »
