Dawn Of The Planet Of The Apes Movie - Sypnosis
This film is a continuation of the
first film in 2011 titled "Rise of the Planet of the Apes" and adapted
from Pierre Boulle's novel, entitled Planet of the Apes. The film "Dawn
of the Planet of the Apes" tells the story of a monkey populations that
had evolved and had a leader with a call to Caesar that over time they
grow. But their existence is threatened by humans who survived the
deadly virus disaster a decade earlier.
Caesar leads the new generation, monkeys live in groups in the forest Muir. Caesar's son, Blue Eyes and Ash met with a man in the woods. Carver (human) panicked and fired to injure Ash. Carver calling other men, a group of men led by Malcolm. Meanwhile, Blue Eyes call other monkeys. Caesar asking people to leave the monkey forest and back to the place of human life in a tower, in San Francisco. These humans are genetically immune to the virus, live in a ruined city. Kera grudges since been persecuted by man asked Caesar to destroy man. Together with a group of great ape, Caesar into town to deliver the message that apes do not want to fight. He asked the man to remain in town, while macaques also remained at their residence in the woods.
Malcolm gives three days to make peace with the apes. The goal is to get access to the water dam which is within the monkey forest. The dam is needed by humans to turn on the electricity in the city. Malcolm tried to speak to Caesar in order to obtain permission to enter the dam. Caesar agreed, provided that Malcolm and his group surrendered their arms
Koba managed to find the armory and dealing with Caesar. Caesar angry and beat Koba hard, but did not kill him because apes are not allowed to kill a fellow apes. Koba returned to the armory, stole a rifle and kill two men. He killed Carver and stole the match.
Dams can eventually be repaired and turn the power supply in the city. They made a celebration, while, Koba burning villages monkeys using lighters stolen from Carver. Koba shoot to kill Caesar in the chest. In the midst of panic, Koba took over the leadership and blamed Malcolm. Koba even ordered to play against a human.
Malcolm and his group escape from the pursuit Koba. Kera looted the armory and attacked groups of people with weapons. while Dreyfus managed to escape to the basement. Koba kill Ash and imprison all the monkeys were loyal to Caesar.
Blue Eyes back to the tower and freeing humans and apes. Malcolm met Dreyfus who said that the assistance of the military base was on his way to help fight the apes. Ape free to join Caesar's face Koba in the top of the tower. When Caesar and Koba fight, Malcolm failed to prevent Dreyfus who detonated explosives C-4 under the tower. The explosion brought down most of the tower, along with Caesar beat Koba and dropped to the edge of the tower. Caesar refused rescue Koba will fall. Caesar said Koba no longer a true apes and let him to his death.
Malcolm tells Caesar that human soldiers will come. They both mourn the loss of opportunities for peace humans and apes. Caesar told Malcolm that man would never forgive ape for a war they started. He asked Malcolm to go for safety. Malcolm slipped away into the shadows, while Caesar stood before the ape army, waiting for the battle to come.

Ouija is a horror movie which released at 2014,and the character of this movie is:
The Synopsis Ouija:
In the opening scene, two young girls, named Laine and Debbie, are sitting in Laine's room playing with a Ouija board. Debbie tells Laine how to play and how to use the planchette to see any spirits. They say the mantra, "As friends we gathered, hearts are true; spirits near, we call to you." Laine looks through the planchette to spot a spirit, and is frightened when she sees someone, only it's her younger sister Sarah. She yells at Sarah to leave.
In the present day, the adult Debbie (Shelley Hennig) is playing with the Ouija board by herself. She appears distressed, and she tosses the board and planchette into the furnace. She then speaks on the phone with the adult Laine (Olivia Cooke). Laine goes over to her house, and Debbie says she is not up to hanging out with her and their friends that night. Debbie mentions playing the Ouija board and feeling odd, though Laine dismisses this as her being a spaz. After Laine leaves, Debbie goes back upstairs and sees the Ouija board and planchette on her bed. She looks through the planchette, and her eyes turn white. Debbie then grabs some Christmas lights and hangs herself.
The next morning, Laine is with her boyfriend Trevor (Daren Kagasoff) at a diner. They are met by their waitress friend Isabelle (Bianca A. Santos). Laine gets a text from her dad saying to go home immediately. When she gets there, Laine finds her dad, her grandmother, and Sarah (Ana Coto) gathered to inform her of what happened to Debbie.
All of Debbie's loved ones gather for the wake. Laine is too shaken to be there, but she holds it together. Debbie's boyfriend Pete (Douglas Smith) arrives with some flowers. Laine goes into Debbie's room where Debbie's mother finds her. Laine breaks down and hugs her. She asks Laine to housesit for them while they are gone. Laine agrees.
Laine discovers the Ouija board that Debbie was playing with. Since she cannot shake the feeling that Debbie's presence is still in the house, she gathers Sarah, Trevor, Pete, and Isabelle to Debbie's house to play with the board. They get together and say the mantra as they put their hands together on the planchette. It starts to move, which everyone thinks is Sarah moving it. The spirit implies that it is Debbie and it spells out "Hi Friend" on the board. The friends are freaked out and stop playing.
Each friend is followed by the spirit. Trevor encounters it on a bike ride, leading him under a bridge where he sees "Hi Friend" written on the wall in chalk. Isabelle sees it spelled out in her car window, along with a hand slamming against it. Pete sees it carved in his desk.
Thinking that Debbie is trying to communicate with them, the friends get together to play the board again. They learn that the spirit is not Debbie, but someone that identifies as DZ. Laine looks through the planchette and sees a little girl with stitches on her mouth. The spirit then spells out on the board, "Run. She's coming." Laine asks who is coming, and the spirit spells "Mother." Laine looks through the planchette and sees the girl point to an older female spirit screaming and running in her direction.
In her home, Isabelle is flossing her teeth and drawing herself a bath. She then has stitches form on her mouth, and she is levitated in the air. The spirit drops her, leaving her to slam her head against the sink, killing her.
Trevor is angry at Laine because she made them play the game, which led to Isabelle's death. Laine investigates Debbie's house and finds some pictures of two little girls and their mother. Trevor looks up on the internet an article on a missing girl from the same address as Debbie's home, as well as the girl's sister being taken into custody after murdering her mother.
Laine goes to a mental asylum to meet Paulina Zander (Lin Shaye), the sister of Doris, the girl with the stitches on her mouth. She tells Laine that their mother believed she heard voices and saw spirits that were trying to communicate through Doris, so she sewed her mouth shut. Paulina asks Laine to find Doris's body in the house and to cut the stitches open.
Laine finds Doris's corpse in Debbie's home, with her mouth still sewed shut. She cuts the stitches open, bringing Doris's spirit out, along with Mother. Doris lets out a blood-curdling scream and vanquishes Mother's spirit.
Just when it seems that everything is over...IT'S NOT. Pete gets killed in his home by Doris's spirit. Laine returns to the asylum to tell Paulina that she did what she told her. Paulina chuckles, and Laine realizes that Mother was not evil, but it was Doris and Paulina that were communicating with spirits, and that their mother was trying to stop them.
Laine's grandmother tells Laine and Sarah that the only way to defeat the spirit is the destroy not only the Ouija board, but Doris's corpse.
The girls and Trevor go to Debbie's house to finish this. Trevor gets pulled into the pool and is killed by Doris. Sarah finds Doris's corpse and is attacked by her spirit. Laine gets out the Ouija board and beckons Doris to play with her. Doris grabs Laine's arm and almost kills her, until Debbie's spirit shows up to intervene. Sarah brings Doris's corpse and throws it into the furnace. Laine throws the Ouija board and planchette, and Doris's spirit is destroyed.
Laine and Sarah return home, relieved that everything is over. Laine flosses her teeth and gets ready for bed, and then finds the planchette on her desk. She picks it up and looks through it one more time.

Nano Technology
The meaning of nano technology is a technology made from
material with dimension at the nanoscale, which makes roughly from 1 to 100
nanometers(nm). Nanotechnology is the way discover made at the nano scale are put to work. The sort answer is theat
material can have different properties at the nano scale, some are better at
conductivity electricityor heat, some are stronger, some have different
magnetic properties, and some reflect light better or change colors as their
size is changed
The applications of nanotechnology is nanofilm, nanofilm is
different nano scale materials can be used in film to make them water-repelent,
anti reflective, self cleaning, ultraviolet or infrared-resistent, or
electrically conductive. Nanofilms are used now on eyeglass, computer display,
and cameras to protect or treat the surface. And the other application of
nanotechnology is nanotubes, which carbon nanotubes (CNTs) are used in baseball
bats, tennis racquets, and some car parts because of their greater mechanical
stenght at less weight per units volume then that of conventional material , nanotechnology is the future
technology with a simple form like nanosacale transistor, solar plastic, which
use in chips’ of computer transistor size have decreasing, so computers have become more powerfull. The
nanotechnology is more efficiently than usual.

Informasi
: Dasar dari sebuah aplikasi
Dasar
dari semua aplikasi yang berarti adalah informasi, dan kita membentuk dan
membangun aplikasi untuk menukar, mengubah, atau menyimpannya. Aplikasi ponsel
tidaklah berbeda. Di bentangan ponsel yang terhubung saat ini, pertukaran
informasi adalah nama dari permainan ini. Untuk mengilustrasikan di poin ini,
bayangkan sebuah ponsel Android tanpa jaringan telepon atau cakupan WiFi.
Sementara masih ada penggunaan telepon seperti itu, anda akan kehilangan akses
ke beberapa banyak aplikasi penting di perangkat anda. Contohnya, surat
elektronik, pesan singkat, penjelajahan jaringan, dan banyak aplikasi lainnya
yang membutuhkan Internet sekarang akan menjadi tidak berfungsi.
Di
bagian lainnya, kita akan memfokuskan usaha kita dalam memeriksa informasi saat
pengangkutannya dan bagaimana mengamankannya. Di bagian ini, kita akan fokus
sebagian besar pada apa yang terjadi pada informasi yang tersimpan
Mengamankan
Aplikasi Anda dari Serangan
Ketika dibuat atau diterima, data
perlu disimpan di suatu tempat. Bagaimana informasi ini disimpan pada akhirnya
akan merefleksikan apakah benar-benar aman. Merilis aplikasi Anda kepada publik
harus dengan pendekatan yang
hati-hati sebagaimana meluncurkan
sebuah website di Internet. Anda harus mengasumsikan bahwa aplikasi Anda baik secara langsung atau tidak langsung akan
diserang dalam beberapa waktu dan bahwa satu-satunya hal yang berada diantara
privasi dan perlindungan data pengguna akhir Anda adalah aplikasi Anda.
Serangan
tidak langsung.
Sedramatis
kalimat terakhir yang terdengar, itu bukan tanpa dasar. Sebelum kita melangkah
lebih jauh, mari kita lihat apakah saya takut mongering dibenarkan. Di bagian
akhir 2010 dan awal 2011, dua kerentanan ditemukan di android versi 2.2 dan
2.3, masing masing. Kerentanan pada dasaranya adalah satu, dimana seorang
penyerang dapat menyalin file yang disimpan pada perangkat SD
Card tanpa izin atau bahkan tanpa isyarat terlihat bahwa hal ini terjadi. kerentanan bekerja seperti pada gambar 2-1.
Card tanpa izin atau bahkan tanpa isyarat terlihat bahwa hal ini terjadi. kerentanan bekerja seperti pada gambar 2-1.
Berikut ini adalah poin yang paling
penting:
- Pengguna mengunjungi situs web berbahaya file hosting, misalnya evil.html.
- Karena satu bagian dari kerentanan, file evil.html-download dan disimpan ke perangkat SD Card tanpa disuruh pengguna.
- Karena bagian lain dari kerentanan, file yang disimpan dapat dibuat untuk mengeksekusi kode JavaScript secepat itu disimpan. sekali lagi, tidak ada desakan untuk pengguna akhir.
- Karena bagian akhir dari kerentanan, JavaScript dijalankan dari titik sebelumnya, karena berjalan di bawah "lokal" konteks perangkat, akan memiliki akses penuh untuk meng-upload file yang tersimpan di SD Card ke situs web dari pilihan penyerang
Untuk
kepentingan argumen, mengasumsikan bahwa aplikasi anda memuat semua data yang tersimpan
pada SD Card untuk penyimpanan dibawah petunjuk itu sendiri. Karena kerentanan
hanya dilewatkan, data yang digunakan oleh aplikasi anda memiliki resiko untuk
dicuri. Banyak perangkat android yang menjalankan aplikasi Anda dan kerentanan
versi firmware menimbulkan resiko pencurian data ke pengguna akhir. ini adalah
contoh dari serangan tidak langsung pada aplikasi anda.
Seberapa
rentan aplikasi Anda dengan serangan tidak langsung tersebut sangat bergantung
pada berapa banyak usaha serangan tidak langsung Anda dalam mengarsitekkan dan
mempertimbangkan aspek keamanan sebelum Anda menulis satu baris kode. Anda
mungkin bertanya, "saya hanya seorang pengembang rancangan aplikasi kecil
untuk menjual aplikasi saya dengan harga yang rendah, jadi apakah saya harus
membuang-buang waktu untuk melakukan begitu banyak perencanaan terlebih
dahulu?" dan saya akan menjawab dengan gemilang, "ya!" apakah
Anda adalah bagian dari sebuah tim dari salah tiga puluh tim pengembang atau
pekerja individu di rumah, sebuah aplikasi arsitek yang baik adalah sesuatu
yang harus selalu anda usahakan untuk diciptakan. saya berharap bahwa ini
adalah apa yang ingin anda pelajari dari buku ini.
Serangan
langsung
Serangan
langsung berbeda secara signifikan dan dapat mengambil banyak bentuk yang
berbeda.Sebuah serangan langsung dapat diklasifikasikan sebagai salah satu yang
ditargetkan langsung di aplikasi Anda.Ini, penyerang mencari untuk memanfaatkan
kelemahan dalam desain aplikasi Anda baik mengumpulkan informationon sensitif
pengguna aplikasi Anda atau untuk menyerang server bahwa pembicaraan aplikasi
Anda.Ambil, misalnya, aplikasi mobile banking. Seorang penyerang dapat pergi
setelah aplikasi mobile milik bank tertentu.Jika desain aplikasi yang lemah
misalnya, jika data sensitif pengguna disimpan dalam bentuk teks, atau
komunikasi antara aplikasidan server tidak dijamin dengan SSLmaka penyerang
dapat kerajinan serangan khusus yang hanya menargetkan thes kelemahan. Ini
adalah serangan langsung pada aplikasi tertentu.Aku akan menutupi serangan
langsung secara lebih rinci dalam Bab 9 dari buku ini.
Proyek 1 = “Proxin” dan penyimpan data
Mari di mulai dengan contoh sderhana yg di sebut proxin. Saya telah di kontrak
untuk menulis aplikasi yang bisa mengirim sms lebih spesifik, menetapkan kontak
dmna pengguna untuk membuat proxi untuk mengatur kordinat gps untuk di
sderhanakan dengan aplikasi ini, pengguna bisa menambahkan istrinya sebgai
kontak dan mempunyai aplikasi sms setiap waktu 3 mile dari tempat kerja dan
rumah dengan cara ini, istrinya dapat mengatahui kapan suaminya di dekat rumah
dan di tempat kerja.
Kamu bisa menmgunduh dan sumber kode untuk aplikasi proxim dari sumber kode
atau mengunduh area dari apress jaringan halaman ( www.apress.com ) untuk kepentingan kejernihan, mari melihat area
yang paling penting.
Setiap kali
pengguna memilih tombol lokasi simpan atau tombol simpan kontak. Ini memicu
kode sebelumnya. mari kita lihat lokasi (lihat daftar 2-2) dan kontak (lihat
daftar 2-3) di klasifikasikan secara
lebih rinci. sementara kita bisa menerapkan salah satu penyimpan rutin utama,
saya menjaga ini terpisah dalam kasus yang kebutuhan untuk bertindak atas objek
yang berbeda dengan cara yang berbeda.

Apa itu Pemisahaan Hak Istimewa ?
Pemisahan Hak Isimewa adalah fitur keamanan yang
penting karena fitur ini menolak satu dari bayak tipe umum serangan. Di banyak
kasus, serangan yang dilakukakan pertama bukanlah serangan yang paling efektif.
Ini biasanya batu loncatan atau pintu gerbang untuk serangan yang lebih besar.
Biasanya, penyerang pertama kali akan mengeksploitasi satu komponen dari
system, dan sekali ada, mereka akan mencoba untuk menyerang komponen yang lebih
penting di system. Jika kedua komponen ini berjalan dengan satu hak istimewa
yang sama, sehingga ini adalah tugas yang sangat sepele untuk penyerang untuk
melompati dari satu kmponen ke komponen selanjutnya. Dengan pemisahaan hak
istimewa, tugas penyerang menjadi sangat sulit. Dia bisa meningkatkan atau
mengganti hak istimewanya kepada komponen yang ingin dia serang. Pada cara ini,
penyerangan berhenti, jika tidak melambat.
Karena Kernel melaksanakan pemisahaan hak istimewa,
ini adalah salah satu inti desain fitur android. Filosofi dibalik desain ini
untuk memastikan tidak ada aplikasi yang dapat membaca atau menulis kode atau
data dari aplikasi lain, pengguna perangkat, atau system operasinya sendiri.
Demikian, aplikasi mungkin tidak dapat semena-mena menggunakan tumpukan
perangkat jaingan untuk menghubungkan remot server. Satu aplikasi mungkin tidak
membaca langsung dari daftar kontak perangkat atau kalender. Fitur ini juga
dikenal sebagai sand boxing. Setelah dua proses yang berjalan di-sandboxes
mereka masing – masing, cara satu – satu nya mereka harus berkomunikasi dengan
satu sama lain adalah untuk meminta izin secara eksplisit unutk meminta data.
Perizinan
Mari kita ambil contoh sederhana. Kita mempunyai
aplikasi yang merekam suara dari mikrofon bawaan dari perangkat. Agar aplikasi
ini bekerja dengan baik, sang pengembang telah memastikan untuk menambahkan
permintaan dari izin RECORD_AUDIO di file aplikasi AndroidManifest.xml. ini
mengizinkan aplikasi kita untuk meminta izin untuk menggunakan komponen system
yang menangani perekaman suara. Tetapi yang menentukan apakah untuk memberi
atau menolak akses? Android mengizinkan pengguna akhir untuk menampilkan proses
terakhir persetujuan ini. Ketika pengguna memasang apliksai kita, dia diminta
dengan menampilkan layar di angka 1-4. Itu bermanfaat untuk mencatat cepat
untuk perizinan yang akan berlangsung ketika mengeksekusi aplikasi. Sebagai
gantinya, perizinan perlu diberikan pada waktu pemasangan.
Jika kita tidak secara ekspilisit mengatur kebutuhan
kita untuk izin RECORD_AUDIO, atau jika pemilik perangkat tidak memberikanv
kita izin setelah kita memintanya, kemudian sebuah pengecualian akan dilempar
oleh VM dan aplikasi akan gagal. Ini terserah kepada sang pengembang untuk
mengetahui permintaan izin dan menangani scenario dimana izin tidak diberikan dengan
menangkap pengecualian yang terkait. Untuk meminta izin ini, label berikut
harus dimasukan kedalam data AndroidManifest.xml dari proyek :
<uses-permission
android:name=”android.permission.RECORD_AUDIO” />
Daftar penuh
dari perizinan diberikan di buku lampiran ini.
Penandaan Kode Aplikasi
Banyak aplikasi yang
dijalankan pada sistem operasi Android yang harus di tandatangani. Android
menggunakan sertifikat pengembang individu dalam pemesanan untuk
mengidentifikasi mereka dan mendirikan hubungan terpercaya di antara banyak
aplikasi-aplikasi yang dijalankan dalam sistem operasi tersbut. Sistem operasi
tidak akan mengijinkan sebuah aplikasi yang tidak tertandatangani untuk di
kelola. Penggunaan sebuah sertifikat pewenang untuk menandai sertifikat tidak diperlukan,
dan android akan dengan mudah menjalankan banyak aplikasi yang telah tertanda
dengan
Seperti izin
pemeriksaan, sertifikat pemeriksaan dilakukan hanya pada saat pemasangan
aplikasi. Oleh karena itu, jika sertifikat pembangun anda sudah berakhir setelah
aplikasi anda terpasang di perangkat, maka aplikasi itu akan terus dikelola.
Yang membuat perbadaan pada poin ini hanyalah anda harus menghasilkan
sertifikat baru sebelum anda dapat membubuhkan aplikasi baru lainnya. Android
membutuhkan dia sertifikat terpisah untuk menelusuri versi dari aplikasi anda
dan mengeluarkan versi dari aplikasi anda. Biasanya, lingkungan Eclipse yang
menjalankan alat pengembangan android (APA) telaj disusun untuk membantu
mengembangkan kunci anda dan memasang sertifikat anda, sehingga aplikasi anda
dapat di bungkus dan ditandai secara otomatis. Program simulasi sistem android
menunjukkan reaksi identik dengan perangkat fisik. Seperti perangkat fisik, itu
hanya akan mengelola aplikasi tertanda. Kami akan menutupi kode aplikasi tertanda
secara detail, sebaik penerbitan dan penjualan aplikasi anda secara online.
Rangkuman
Seperti yang
kita lihat sejauh ini, Android menerima dorongan luar biasa dalam sumber daya
dan perhatian berkat pengambilalihan Google terhadap Android. Perawatan dan
perhatian yang sama ini telah membantu propel Android ke salah satu sistem
operasi smartphone yang tumbuh paling cepat di dunia saat ini. Model open
source Android telah membantu jumlahnya bertambah, terutama karena banyak
produsen hardware yang berbeda yang dapat menggunakan sistem operasi di ponsel
mereka.
Kita juga telah melihat
bahwa inti dari Android didasarkan pada kernel Linux. Dua tugas utama kernel
adalah (1) untuk melayani sebagai jembatan antara hardware dan sistem operasi,
dan (2) untuk menangani keamanan, manajemen memori, dan jaringan. Kernel
biasanya salah satu komponen utama yang akan diubah ketika produsen hardware
yang berbeda mulai mengadopsi Android untuk bekerja dengan perangkat keras
mereka.
lapisan berikutnya yang
terjadi di sekitar kernel Android adalah lapisan runtime yang terdiri dari
perpustakaan inti dan Dalvik mesin virtual. Dalvik VM adalah bagian mendasar dari pelaksanaan aplikasi Anda pada
platform android. Karena Anda
akan melihat dalam bab-bab berikutnya, Dalvik VM memiliki beberapa fitur unik
ketika datang ke mengeksekusi aplikasi dengan aman dan efisien dalam lingkungan
terbatas sumber daya
Lapisan
atas berikutnya yang akan ditambahkan adalah kerangka
kerja dan aplikasi, masing-masing.
Anda dapat memikirkan lapisan kerangka seperti jembatan lain antara API
Java dan kode asli dan sistem proses
asli berjalan di
bawah. Ini adalah di mana semua
API Java Android
hidup. Semua perpustakaan yang ingin Anda impor ke dalam program Anda diimpor
dari sini. Lapisan aplikasi adalah di mana
aplikasi Anda akhirnya
akan hidup dan bekerja. Anda akan berbagi
ruang ini dengan aplikasi pengembang lain dan aplikasi
Android dibundel seperti
telepon, kalender, e-mail dan pesan aplikasi.
Kita
kemudian melihat sebentar di risiko keamanan, bagaimana Anda memiliki tanggung jawab untuk melindungi
pengguna akhir Anda, dan beberapa cara di mana Android memfasilitasi ini.
tiga daerah yang
kita lihat adalah pemisahan hak
istimewa, hak akses, dan kode aplikasi penandatanganan. Di bab-bab berikutnya, kita
akan membahas apa yang dapat Anda lakukan tidak hanya untuk memanfaatkan fitur ini, tetapi juga menambahkan
sendiri tingkat keamanan dan pengguna akhir perlindungan.
