Cara Singkat Membuat Photoshop Hybrid Animals

Hasil foto Hybrid Animals (Foto: Mashable

 
Tak ada yang tidak mungkin dengan sentuhan Adobe Photoshop. Ya, seperti yang diketahui dengan aplikasi foto ini Anda bisa mengedit atau menghasilkan gambar apapun sesuai dengan keinginan Anda.

Terlebih ketika Photoshop telah menyambangi di berbagai perangkat mobile, tentu memberikan Anda kesempatan untuk bereksperimen dengan berbagai fitur yang ditawarkannya. Salah satu kegiatan yang menghibur adalah Anda bisa mengedit foto dengan menggabungkan dua spesies hewan (sebut saja A dan B) menjadi satu.

Anda yang penasaran bagaimana cara menggabungkan dua spesies dalam satu foto, ikuti langkah-langkah berikut ini sebagaimana disadur dari Mashable, Senin (29/7/2013):

Cari Gambar Anda
Ketika Anda memilih dua gambar hewan dalam galeri foto, pastikan bahwa mereka memiliki pose dan komposisi yang sesuai. Hal ini dilakukan untuk memudahkan penggabungan efek keduanya. Jika salah satu kepala objek (hewan) menghadap ke samping, sementara tubuhnya menghadap ke depan maka akan sulit mencapai ilusi yang tepat. Namun apabila Anda belum yakin apakah keduanya akan cocok, cukup tempatkan salah satu gambar di atasnya dan ubah tingkat kegelapan (opacity) untuk mengukur secara kasar.

Buka kedua gambar yang Anda pilih tersebut di Photoshop dan bersiaplah untuk memulai proyek menyenangkan ini.

Pilih Layar Background
Buat latar belakang menjadi seperti lapisan (layer) pada gambar, sehingga Anda dapat memulai editing dengan latar belakang yang transparan. Caranya, klik kanan layer background dan pilih “Layer from Background…”. Kemudian, klik OK.

Buat Latar Belakang Transparan
Misalnya, Anda sudah memilih kepala dari gambar A. Gunakan 'Eraser Tool' untuk menghapus latar belakang pemandangan yang sudah ada sebelumnya. Lalu pilih elemen untuk menghapusnya secara halus lagi di 'Magic Wand Tool'. Anda bisa menggunakan Wacom Tablet untuk mendapatkan hasil yang lebih efektif dan cepar dalam menghilangkan detil yang sulit di sekitar objek A.

Gabungkan Kepala A ke Gambar B
Salin potongan (crop) kepala A dan timpa di atas gambar tubuh B. Anda hanya perlu mengubah ukuran kedua gambar tersebut agar pas dengan menggunakan Transform Tool (Command atau Ctrl+T). Ketika Anda sedang mengubah ukuran gambar, coba untuk tidak memperbesar ukuran gambar tersebut dari ukuran awalnya. Karena, Anda akan kehilangan kualitas gambar di hasil akhirnya.

Dalam mencocokkan dua objek ini, Anda cukup dengan membalikkan gambar secara horizontal dan sedikit memutarkan kepalanya agar tampak lebih nyata.

Campurkan Warna
Langkah selanjutnya, padukan warna keseluruhan antara kepala A dan tubuh B tersebut. Untuk hasil yang lebih baik, Anda bisa menduplikasian kepala A terlebih dahulu. Misalnya, dengan label bernama “Kepala A desaturated”. Selanjutnya, lakukan perintah berupa Command+U (Ctrl+U pada PC) dan pindahkan tingkat saturation hingga -48.

Rapikan
Gunakan efek blur untuk menambah kesan yang sempurna pada perpaduan dua lapis foto. Masih dengan menggunakan crop dari layar “Kepala A Desaturated”, kemudian perhalus kedua objek tersebut dengan menggunakan Tool Liquify di atas menu Filter (atau dengan menggunakan perintah Shift+Command+X/Shift+Ctrl+X).

Dalam menu Liquify, pilih Forward Warp Tool dan kuas berukuran 150. Selanjutnya, klik Ok dan kembali ke gambar Anda. Lalu, gunakan Clone Stamp Tool untuk mencocokkan warna bulu antara objek A dan B.

Untuk memperbaiki penampilan, pilih opsi Filter dan Gaussian Blur. Atau ubah tingkat blur menjadi 2,0 pixel dan klik Ok. Terakhir, sesuaikan tingkat warna pada kedua objek yang sudah digabungkan dengan cara pilih Image> Adjustment> Levels (Command+L).

Sentuhan Akhir
Gambar akan terlihat lebih bagus lagi ketika gambar yang sudah digabungkan itu, diperhalus lagi dengan sikat Soft Round. Selamat mencoba!

Penyebab Email, Facebook, Twitter Kena Hack


Berbagai alasan facebook kena hack, berbagai sebab email kena hack, twitter kena hack. Apa sih sebenarnya yang terjadi?
Yuk, mari kita telaah lebih dalam lagi, apa yang sebenarnya terjadi:
Kita mulai dari diri kita sendiri:
  • Terkadang kita kurang terliti dan kurang hati-hati dalam menyikapi sesuatu, disertai dengan andrenalin yang tinggi yang ada pada diri kita, sehingga menyebabkan kita tedor dan lupa atas apa yang kita lakukan.
  • Kurang waspada dan jeli dalam melihat sesuatu, sehingga membuat segala sesuatu menjadi buta, tuli & tak berasa.
  • Kurang merasa memiliki dan kurang menjaga apa yang kita miliki, sehingga kita membuat mudah dan menganggap enteng segala sesuatu.
Dari penjelasan diatas, beberapa hal yang menyebabkan email, facebook, twitter, dsb kena hack adalah:
  1. Kurang jeli memperhatikan URL Address (Alamat URL), misalkan: http://www.facekook.com, http://facebook.website.com, padahal URL yang sebenarnya adalah http://www.facebook.com. Nah jika anda mengklik situs tersebut, maka anda sudah masuk jebakan batman, karena mungkin bisa saja isi dari website dapat mengandung scam / phising / fakelogin / virus / malware, dsb & Account Anda Raib!
  2. Tergiur dengan tipuan yang menggoda, sehingga terjebak pada kesalahan yang fatal, misalkan: “Foto Bugil Artis ABCDE, silakan klik link berikut: http://www.andaterjebak.com“, “Video Mesum Aktor CDEFGH, Baru Loh, silakan klik: http://www.artisvideoporno.com“, “Hadiah besar menanti, Blackberry gratisan: http://www.webpalsugratisan.com“, dan masih banyak tipuan & trik yang lainnya. Sudah pasti tahu apa yang akan terjadi bila mengklik situs tersebut, maka bisa jadi akan bertemu link scam / phising / fake login / virus / malware /spam & Account Anda Terhack apabila anda melakukan penginputan user & password email di situs tersebut!
  3. Tidak pernah berfikir bahwa ada “Backdoor, Trojan, Spyware, Keylogger” dalam komputer yang digunakan saat ini, sehingga lupa untuk melakukan checking terhadap aplikasi & service yang sedang berjalan saat ini. Misal: Windows -> Tekan “CTRL+ALT+DEL“, kemudian muncul Taskmanager, checklah aplikasi & service yang berjalan, apabila ada aplikasi / service yang mencurigakan silakan di “End Process / End Task”. Linux: Tinggal ketik “ps- aux”, kemudian kill -9 aplikasi yang mencurigakan. Hapuslah autorun melalui regedit di windows atau hapus crontab di Linux.
  4. Kebanyakan tidak mengetahui bahwa password email, facebook, twitter, dsb haruslah BERBEDA. Jika password keseluruhan account yang kita miliki sama, maka akan mempermudah sang hacker untuk memasuki account kita yang lainnya. Namun yang paling penting adalah JAGALAH PASSWORD EMAIL DENGAN BAIK, karena email merupakan akar dari account yang lainnya. Misal: Password email “h4Ck3r$3jAt1“, password facebook “f@c3b()()kk03“, pasword twitter “b3rk#!c@u“, yang terpenting adalah harus berbeda & mudah di ingat.
  5. Email dianggap sesuatu yang kedua, karena sangat gampang untuk membuat email, hingga password email lupa karena hampir tidak pernah membuka email yang dibuat. Password email saja lupa, apalagi “Secret Question” nya, ketika dalam kasus Facebook, Twitter terkena hack, maka akan sangat sulit untuk merecovernya kembali.
  6. Malas untuk melakukan update account profile / account setting terhadap email, facecook, twitter, dsb. Sehingga informasi mengenai “Alternate Email, Secret Question, Alamat, No. Telp” kadang di isi sembarangan bahkan kadang tidak di isi. Inilah account yang sudah kena hack tidak akan pernah kembali lagi kepada pemiliknya.
  7. Tidak ada waktu untuk melakukan perubahan secara berkala terhadap password, passwordnya selalu sama dari awal pembuatan sampai saat ini. Inilah yang dapat menyebabkan password masih bisa dipakai andaikan password sudah masuk dalam log sang hacker walaupun lognya sudah 1-2 tahun yang lalu.
  8. Mengisi password secara sembarangan, mudah untuk ditebak & password yang lemah, misal: “abcdef”, “12345″, “21101986″, “201282″, “ayulovejelek”. Biasanya kebanyakan orang mengisi password dengan “Tanggal Lahir, Namadepan & Belakang, Hari Spesial, Nama Pacar, No. HP, Keluarga“. Password harus dibuat minimal terdapat “Alfabet Character, Angka, Symbol & Panjangnya Minimal 10 Character” hal ini bertujuan untuk memperkuat password, password harus sesuatu yang berbeda yang mudah di ingat oleh kita sendiri dan untuk mempersulit ketika ada aktifitas BruteForce terhadap Account.
  9. Hal yang paling sering adalah “Lupa Logout & Lupa Clear Browsing History” setelah kita melakukan aktifitas browsing di internet sehingga kebanyakan sang hacker menggunakan cookies yang sebelumnya untuk mengambil alih account & tentu saja account akan hilang ditelan malam. Kebanyakan hal ini terjadi di warnet atau tempat public internet.
  10. Salah satu yang paling  rentan & karena malas untuk mengisi password, sehingga yang digunakan adalah “Remember Password“, sebaiknya walaupun itu laptop pribadi, pc pribadi, sebaiknya kita tinggalkan kebiasaan ini, karena cukup mudah untuk mengambil account apabila ada “remember password”. Terdapat tools yang juga bisa merecover password yang disave di Browser.

Beberapa hal tersebut yang membuat account terkena hack, akan saya berikan Clue kepada Pembaca  yang setia:
  1. Manusia adalah VULNERABILITY (Sebuah Kelemahan / Kerentanan) yang TIDAK PERNAH BISA DI PATCH! Jika sang hacker sudah pusing & tidak berhasil untuk menghack system. Maka sasarannya adalah MANUSIA itu sendiri, karena Manusia memiliki kelemaan yang tidak pernah bisa di PATCH, kecuali atas se ijin Yang Maha Kuasa :)
  2. Setiap saat dan setiap waktu setiap ada Bug di sebuah system, developer akan bertindak untuk melakukan PATCH. Oleh sebab itu TIDAK AKAN PERNAH MUDAH UNTUK MELAKUKAN HACK ACCOUNT DIDALAM SYSTEM THE BIG 5 (GOOGLE, YAHOO, MICROSOFT, FACEBOOK, TWITTER). Jadi sebaiknya berhati-hatilah apabila ada jasa penawaran untuk melakukan hacking “Yahoo, Facebook, Gmail, Twitter” dsb, apalagi meminta bayaran & via online. Yang pasti duit anda akan raib begitu saja.
Untuk pembaca setia , tetap waspada, teliti, hati-hati dalam menyikapi sesuatu & JANGAN MUDAH TERTIPU oleh orang yang tidak bertanggung jawab. Karena jujur saja, banyak Inbox yang masuk di email saya yang meminta bantuan untuk recover password, hack password, facebook kena hack, yahoo kena hack, hotmail kena hack, gmail kena hack, dan ada juga yang tertipu karena melakukan pembayaran tetapi barang  tidak dikirimkan

Tehnik hackers menerobos keamanan (Sebagai bahan Pembelajaran danjangan disalahgunakan)

By: Awer Ehm

Aktifitas hackers (*sesungguhnya yang saya maksudkan adalah crackers, tapi media massa telah salah mempopulerkannya*) adalah nyata dan menjadi ancaman serius yang terus menerus berkembang serta dapat mengganggu kegiatan bisnis. Mereka masuk dalam sistem internal perusahaan melalui sambungan internet / LAN atau kegiatan secara fisik lainnya yang memungkinkan mereka terhubung ke terminal komputer.

Berikut disampaikan secara umum beberapa tehnik yang biasa dipakai hackers untuk mendapatkan akses ilegal ke sumber daya komputer.

A. Mencuri akses log-in yang dipakai

Untuk melakukan akses ilegal ke dalam sistem komputer salah satunya adalah dengan mendapatkan akses log-in yang dipakai. Hal ini bisa dilakukan ketika hacker secara fisik berada di dekat fasilitas komputer atau berusaha mengakses sistem melalui koneksi dial-in.

1. Mencuri akses secara fisik : tahap penting dalam menjaga keamanan sistem informasi adalah menjamin bahwa akses secara fisik ke sumber daya komputer adalah terbatas. Orang dalam atau luar yang secara fisik mempunyai akses ke terminal komputer akan memiliki kesempatan mendapatkan log-in yang sedang digunakan.

2. Mendapatkan akses melalui dial-in : metode lain untuk mendapatkan akses log-in adalah dengan melakukan dial-in ke host. Program “daemon dialers”, yang banyak tersedia di internet, dapat mengidentifikasi ID modem yang sedang berlaku. Sekali hackers mengetahui ID modem suatu terminal/host, dia dapat melakukan dial-in dan mendapatkan akses log-in yang dipakai.

Untuk meminimalisir potensi pelanggaran akses log-in ini dapat dilakukan langkah-langkah :

- Terminal komputer diletakkan (secara fisik) ditempat yang aman;
- Pengamanan dan pengendalian akses yang baik dipasang pada semua jendela dan pintu tempat dimana hardware komputer berada;
- Komputer yang diletakkan diluar area yang diamankan dan terhubung ke jaringan perusahaan, harus menggunakan password yang baik;
- Mematikan modem ketika tidak digunakan;
- Menggunakan fasilitas call-back, memberikan ekstra otentikasi, atau menggunakan one-time password;
- Menghilangkan logo dan nama organisasi dari layar log-in untuk menghilangkan tanda pengenal, sehingga hackers tidak dapat mengetahui dengan cepat sistem mana yang dimasuki;
- Menggunakan alarm atau pesan peringatan saat pihak yang tidak berhak memasuki sistem dan mencatat aktifitasnya.

B. Mencuri password

Beberpa tehnik yang populer untuk mencuri password adalah :
1. Brute Force Attacks : merupakan usaha menebak password baik secara manual ataupun otomatis. Umumnya hackers memiliki daftar password yang berisi koleksi password default yang terpasang secara otomatis saat suatu program diinstal. Program penebak password banyak tersedia juga di internet.
2. Password cracking : merupakan program untuk mendapatkan password dengan memanfaatkan celah keamanan. Program ini banyak tersedia di internet, misalnya program Crack. Crack bekerja dengan cara menyandi kamus standar dan kemudian membandingkannya dengan password yang disandi oleh sistem sampai menemukan kata-kata yang cocok.

Untuk menghindari pencurian password dapat dilakukan langkah-langkah :
- Mem-password semua user account;
- Ganti default password segera setelah instal program;
- Gunakan kata-kata / frasa yang sukar ditebak;
- Ganti password secara periodik;
- User account yang sudah tidak terpakai segera dihapus;
- Password yang telah disandi disimpan dalam file yang terlindung dengan baik (disamarkan);
- Jangan menuliskan password didekat terminal komputer / work station;
- Usahakan hanya sedikit orang yang memiliki akses terhadap sistem administrator, untuk menghindari resiko peng-copy-an password yang sedang digunakan;
- Memberikan pengertian kepada user akan pentingnya mengelola, menjaga keamanan password yang dimiliki.

3. Keystroke logging : tehnik ini sangat sederhana dan hampir selalu tidak terdeteksi. Hackers dapat menggunakan sebuah disket untuk menginstal program key-stroke logging melalui work-station. Sekali program ini masuk ke dalam sistem, dia akan menetap di dalam sistem dan menangkap setiap sign-on berdasarkan kata kunci pembukanya. Hacker dapat memanfaatkan sign-on yang tertangkap tersebut dari jauh (remote location).

Untuk mencegah aksi ini :
- Gunakan one-time password untuk sign-on pada account dengan tingkat sensitif tinggi;
- Secara periodik lakukan scanning untuk mengetahui trojan atau malware lain yang terlanjur masuk kedalam sistem;
- Tempatkan hardware komputer di tempat yang terlindung dan diberi pembatasan akses.

4. Packet sniffing : program-program network monitoring tools seperti network analyzers dan packet sniffers tersedia sangat banyak di internet. Tool ini bekerja dengan cara menangkap paket data yang ditransmisikan melalui saluran komunikasi. Terkadang hacker juga melakukan packet sniffer dengan cara menghubungkan laptopnya ke port jaringan perusahaan, baru kemudian melakukan pencurian data.

Lalu-lintas data dalam jaringan hampir dapat dipastikan tidak dibungkus dengan metode penyandian yang baik, sehingga merupakan kesempatan emas bagi hacker untuk mendapatkan user account dan password yang ada di dalam jaringan.

Untuk mencegah dan meminimalisir akibat aksi packet sniffer :
- Jalur komunikasi sedapat mungkin dibagi dalam beberapa bagian;
- Data-data sensitif ditransmisikan melalui jaringan komunikasi dalam bentuk yang sudah disandi dengan metode penyandian yang baik;
- Menggunakan one-time password untuk sign-on pada account dengan tingkat yang sensitif;
- Akses kepada saluran komunikasi dan komputer, secara fisik dibatasi.

5. Social engineering : interaksi sosial yang mengabaikan keamanan informasi menjadi salah satu cara hackers untuk mendapatkan data sensitif secara langsung ataupun tidak langsung dari user.

Untuk mencegah kebocoran informasi melalui kegiatan ini :
- Secara periodik dilakukan penyegaran dan sosialisasi pentingnya menjaga keamanan informasi yang dimiliki;
- Melakukan pencatatan dan dokumentasi atas semua prosedur pengendalian akses;
- Membangun kesadaran pengamanan informasi di seluruh staf baik manajemen maupun operasional;
- Waspada terhadap pesan tipuan yang berisi “permintaan konfirmasi password”, “reset password” atau “lupa password”.

C. Metode lainnya untuk mencuri akses

1. IP address spoofing : adalah salah satu cara pengelabuan yang membuat untrusted host terlihat seperti trusted host dalam sebuah jaringan. Hal ini terjadi karena hackers merubah IP address host tersebut sehingga menyerupai trusted host. Dengan kata lain penyusup menipu host dalam jaringan sehingga penyusup tersebut tidak perlu melakukan otentikasi untuk dapat terhubung dengan jaringan lokal.

Untuk menangkal serangan ini dilakukan :
- Mengkonfigurasi firewall dan router sedemikian rupa agar dapat menangkal serangan IP spoofing;
- Hanya host yang dinyatakan aman yang diijinkan untuk terhubung ke dalam jaringan.

2. Terminal yang tidak dijaga : sering terjadi sebuah terminal dalam keadaan sign-on ditinggalkan oleh user, entah ke toilet atau istirahat makan. Bila kebetulan ada hacker yang secara fisik berada di tempat tersebut, maka hacker akan mempunyai kesempatan untuk mengakses data secara ilegal atau memasukkan trojan ke dalam sistem.

Untuk meminimalisir kejadian tersebut :
- Gunakan screen server yang dipasangi password, yang otomatis dijalankan setelah beberapa menit tidak ada aktifitas dalam sistem;
- Memberi pengertian pada user untuk selalu melakukan sign-off setiap kali meninggalkan terminal;
- Melakukan pengawasan ditempat dimana terminal tersebut berada.

3. Writeable set user ID files : beberapa sistem menyediakan sebuah file penyimpan user ID untuk mengakses terminal. Hacker akan mencari file yang diidentifikasikan sebagai set-user-ID (SUID) tersebut dan mencoba menuliskan kode tambahan kedalam SUID agar mendapatkan akses menuju root.

Untuk mencegah penyusupan ini :
- Dilakukan pembatasan terhadap program yang dapat mengakses SUID;
- SUID dikonfigurasikan sedemikian rupa sehingga hanya dapat diubah melalui root;
- Hanya user yang terdaftar dalam sistem yang dapat menulis di file SUID.

4. Laporan dari Computer Emergency Response Team (CERT) : CERT selalu memberikan laporan-laporan tentang celah keamanan yang teridentifikasi. Namun eksploitasi ini sering dimanfaatkan oleh pihak yang bermaksud jahat untuk mendapatkan keuntungan dengan memasuki sistem secara ilegal. Hackers selalu mengikuti laporan CERT ini untuk mengidentifikasi bugs baru dari suatu sistem.

Administrator jaringan dan profesional keamanan informasi perlu mengikuti dengan cermat laporan-laporan CERT, melakukan checksum untuk menguji hasil-hasil yang dilaporkan CERT sebelum diimplementasikan dan melakukan penutupan celah keamanan yang teridentifikasi.

5. Hackers bulletin board : hackers dari seluruh dunia saling bertukar informasi dalam internet melalui forum atau milis dan bahkan menerbitkan laporan/tulisan dalam buletin. Mereka membahas masalah celah keamanan, keamanan sistem informasi, berbagi tehnik dan program baru, atau bahkan membahas informasi sensitif milik organisasi tertentu.

Administrator dan profesional keamanan jaringan perlu juga secara teratur mengikuti perkembangan pembahasan di forum hackers, dengan tujuan memperkuat sistem keamanan informasi dalam organisasinya.

6. Software di internet : internet banyak sekali menyediakan program/tools yang dapat digunakan oleh administrator untuk membantu melindungi komputer dan membantu melakukan scanning celah keamanan. Namun tool tersebut juga dipakai para hacker untuk maksud yang sebaliknya.

Administrator jaringan perlu secara teratur melakukan audit terhadap sistemnya. Audit ini dapat dilakukan secara internal ataupun melalui konsultan independen. Selain itu secara reguler administrator perlu mengecek versi terakhir dari tool yang digunakan untuk membantu keamanan sistem. Serta pastikan setiap celah keamanan yang ditemukan telah diatasi dengan baik. -antz-

Cara Membuat Menu Tab View

Karena sering ditanya tentang bagaimana caranya membuat Tab VIew (Biasanya nanyanya gini: "Mas cara membuat menu yg kayak punya mas gmn? yg ada "Tips & Trik", "Lain-lain", "Terbaru", "Komentar" itu lho). Ya kan? hayo ngaku... Tabview itu sangat berguna sekali, karena dengan ukuran kotak yang relatif kecil tapi bisa memuat isi yang buanyak. Sebenarnya dah dari dulu pingin posting tentang itu, tp karena yg dulu cara pasanganya sulit jadi belum bisa aku jelaskan. Trus akhirnya aku menemukan metode baru dalam pembuatannya. Cara yang ini mungkin mirip dengan punyanya o-om, tp scriptnya agak beda. Dan aku dapet script ini juga bukan dari o-om lho :D
Tab view itu contohnya seperti ini :




Beginilah cara untuk membuat menu tab view tersebut

1. Login ke blogger trus pilih menu "Layout --> Edit HTML"
2. Kemudian cari kode ini ]]></b:skin>
3. Kemudian masukkan kode berikut ini sebelum kode ]]></b:skin> atau kedalam tag CSS.
div.TabView div.Tabs
{
height: 24px;
overflow: hidden;
}
div.TabView div.Tabs a
{
float: left;
display: block;
width: 90px; /* Lebar Menu Utama Atas */ text-align: center;
height: 24px; /* Tinggi Menu Utama Atas */
padding-top: 3px;
vertical-align: middle;
border: 1px solid #000; /* Warna border Menu Atas */
border-bottom-width: 0;
text-decoration: none;
font-family: "Times New Roman", Serif; /* Font Menu Utama Atas */
font-weight: 900;
color: #000; /* Warna Font Menu Utama Atas */
}
div.TabView div.Tabs a:hover, div.TabView div.Tabs a.Active
{
background-color: #FF9900; /* Warna background Menu Utama Atas */
}
div.TabView div.Pages
{
clear: both;
border: 1px solid #6E6E6E; /* Warna border Kotak Utama */
overflow: hidden;
background-color: #FF9900; /* Warna background Kotak Utama */
}
div.TabView div.Pages div.Page
{
height: 100%;
padding: 0px;
overflow: hidden;
}
div.TabView div.Pages div.Page div.Pad
{
padding: 3px 5px;
}


4. Perhatikan text-text yang berwarna merah, itu adalah keterangan untuk pengaturan Tab View. Ada ukuran warna dll. Untuk mengetahui kode2 warna silahkan lihat DISINI
5. Langkah selanjutnya yaitu pasang kode berikut ini sebelum kode </head>

<script src='http://kendhin.890m.com/blog/tabview.js' type='text/javascript'/>


6. Kemudian "Di save"
7. Lalu pergi ke menu "Page Elements"
8. Trus PIlih "Add a Gadget" --> "HTML/Javascript" di tempat yg akan km letakkan Manu Tab View ini.
9. Inilah script yg harus kamu pasang :

<form action="tabview.html" method="get">
<div class="TabView" id="TabView">
<div class="Tabs" style="width: 350px;">
<a>Tab 1</a>
<a>Tab 2</a>
<a>Tab 3</a>

</div>
<div class="Pages" style="width: 350px; height: 250px;">

<div class="Page">
<div class="Pad">
Tab 1.1 <br />
Tab 1.2 <br />
Tab 1.3 <br />

</div>
</div>

<div class="Page">
<div class="Pad">
Tab 2.1 <br />
Tab 2.2 <br />
Tab 2.3 <br />

</div>
</div>

<div class="Page">
<div class="Pad">
Tab 3.1 <br />
Tab 3.2 <br />
Tab 3.3 <br />

</div>
</div>


</div>
</div>
</form>

<script type="text/javascript">
tabview_initialize('TabView');
</script>


Keterangan :
- Angka2 atau text yang berwarna biru (350px) adalah ukuran tinggi dan lebar tabview.
- Kode yang berwarna Hijau Adalah text yang di Menu utama (Menu Atas).
- Kode yang berwarna merah adalah isi dari tabvie tsb. Kamu bisa mengisinya dengan link, gambar, banner, script dll.
- Untuk menmbahkan jumlah menu maka perhatikanlah text yang berkedip2. tambahkan menu tersebut dibawahnya.

Tutorial John The Ripper (JTR)

Pengenalan

John the Ripper merupakan password cracker yang cepat. JTR tersedia 
pada berbagai 
platform baik *nix, DOS, win32. Tujuan utamanya adalah mendeteksi 
kelemakan 
password pada Unix. Tetapi JTR juga dapat mengcrack password pada Win 
NT/2000/XP 
yang berbentuk LM hashes.

Bagi yang belum mempunyai JTR, anda dapat download disini:
- http://www.ziddu.com/download/14179479/john171w.zip.html


Ada beberapa hal penting pada JTR 
[passfile] - Nama dari password file anda
[wordlist] - Kumpulan kata-kata
[output] - Hasi decrypt password
[session name] - Nama yang anda gunakan untuk menyimpan session

-- contoh Pasword File: passwd.txt --
root:VwL97VCAx1Qhs:0:0:root:/root:/bin/bash
user:aH0qcQOVz7e0s:515:100:user:/home/user:/bin/bash
lin:iWuSGrtezXz0E:515:100:lin:/home/lin:/bin/bash
-- contoh Pasword File: passwd.txt --

Note: Simpan [passfile] di folder yang sama dengan file execute JTR
      Hal ini untuk mempermudah penggunaan JTR :)

Terdapat 3 mode pada JTR untuk mendecrypt password
1. Single Mode
   Pada Single Mode, JTR akan berusaha mencari Password yang paling
   lemah dari seluruh password. Cara ini merupakan cara yang paling
   cepat.

   Syntax single mode
   - john -single [passfile]
     atau
   - john -si [passfile]
  
   Co: Anda mempunyai password file passwd.txt
       Maka penggunaannya : john -si passwd.txt
   
2. Wordfile Mode
   Wordfile Mode merupakan cara tercepat ke 2. Wordfile Mode membutuhkan
   kamus kata-kata. 

   Wordfile syntax
   john -wordfile:[wordlist] [passfile] 
   atau 
   john -w:[wordlist] [passfile] 

   Co: Anda mempunyai password file passwd.txt dan mempunyai kamus kata words.lst
   john -w:words.lst passwd.txt

3. Incremental Mode
   Incremental Mode merupakan cara yang paling lambat dan berusaha untuk 
   mendecrypt semua password, akan memakan waktu berhari-hari, bermingu-minggu,
   bahkan berbulan-bulan (berlebihan gak ya :p). Sebaiknya anda menggunakan 
   cara ini apabila 2 cara sebelumnya gagal.
   Terdapat 4 perintah dasar dalam penggunaannya
   a. digits: Akan mencoba mendecrypt semua password dengan karakter angka
   b. alpha: Akan mencoba mendecrypt semua password dengan karakter huruf
   c. all: Akan mencoba mendecrypt semua password dengan semua karakter 
           termasuk karakter spesial, co: @!^&?
   d. tidak memilih mode: Akan mencoba mendecrypt password dengan segala cara

   Syntax:
   john -i [passfile] 
   john -i:DIGITS [passfile] 
   john -i:ALPHA [passfile] 
   john -i:ALL [passfile] 

   Co: Anda mempunyai password file passwd.txt
   john -i passwd.txt
   john -i:DIGITS passwd.txt
   john -i:ALPHA passwd.txt
   john -i:ALL passwd.txt


Mode lainnya pada JTR
- Show Mode 
  Setelah anda mendapatkan password yang telah di decrypt, anda dapat menyimpannya
  pada file tertentu.

  Syntax:   
  john -show [passfile]>[output]

  Co: Anda mempunyai password file passwd.txt dan ingin menghasilkan output hasil.txt
  john -show passwd.txt>hasil.txt

  Anda juga dapat melihat langsung hasil decrypt dari JTR.

  Syntax:
  john -show [passfile]

TIPS MERANCANG WEB (1)

Menurut survey Netcraf (www.netcraft.com) pada awal bulan September jumlah
web mencapai angka 135,166,473 dari seluruh dunia. Ada pertambahan 7.2 juta
dari bulan kemarin. Jumlah tersebut cukup fantastis, salah satu penyebabnya adalah
bermunculannya online blogging dan web community.
Apakah web sobat termasuk didalamnya?. Mempunyai web adalah
gampang-gampang susah.. Membutuhkan konsistensi dan managemen yang
berkelanjutan. Jika tidak maka web tersebut akan ‘mati’ ditengah-tengah belantara
dunia maya. Bahkan dalam beberapa kasus, web memberikan bad image karena
tidak pernah diupdate atau tidak diurus.
Pepatah bilang memelihara lebih susah daripada membuat. Membuat web atau
blog bisa dibilang mudah bahkan sangat gampang (dalam spesifikasi tertentu),
cukup sedikit mengerti bahasa Inggris dan waktu beberapa menit sudah bias selesai.
Tetapi memeliharanya agar tidak ‘sekedar’ hidup dan dikunjungi pengunjung setia
adalah tidak mudah.
Sebuah website yang ‘sukses’ adalah web yang mampu membius para
pengunjung (netter) untuk selalu ingin berkunjung kembali.

Mengatasi Monitor Buram

Salah satu penyebab monitor CRT (tabung) displaynya buram atau tidak fokus adalah lemahnya bagian komponen Flyback. Komponen ini mudah dikenali, bentuknya hitam dengan salah satu outputnya nempel di tabung monitor. Bentuknya mirip koil dari sepeda motor anda. Flyback memiliki dua pengatur yaitu untuk pengatur fokus dan untuk pengatur terang redupnya display. Biasanya untuk masalah monitor buram yang usianya dibawah tiga tahun, untuk mengatasi buramnya display bisa dengan mengatur fokus dari flyback. Letak pengatur fokus flyback biasnya dibagian atas sedangkan untuk pengatur redup terang di bagian bawah. Putar pengatur fokus sampai posisi yang terbaik. Hati-hati dalam memutar pengatur fokus ini karena kondisi monitor sedang nyala. Bisa menggunakan obeng min atau plus untuk keamanan. Tes kondisi fokus hasil pengaturan tadi beberapa jam, kalau monitor buram atau tidak fokus kembali setelah panas berarti kondisi flybacknya sudah parah. Penyetingan fokus sudah tidak bisa dilakukan. Tapi jangan khawatir monitor buram anda masih bisa diselamatkan. Jika kondisi ini terjadi anda harus mengganti flyback. Cuma masalahnya jenis flyback dengan tipe yang sama suka jarang di pasaran.Langkah yang bisa dilakukan adalah melakukan "pencangkokan flyback". Yaitu sebuah trik untuk mengatasi lemahnya komponen pengatur fokus pada flyback. yaitu dengan menggabung flyback lama dengan flyback baru yang fokusnya bagus. flyback baru untuk cangkokan boleh berbeda type dengan yang di cangkok. Langkah-langkah pencangkokan flyback akan ditulis di ringkasan selanjutnya.

Weapons of War - Machine Guns

Vickers machine gun The machine gun, which so came to dominate and even to personify the battlefields of World War One, was a fairly primitive device when general war began in August 1914.  Machine guns of all armies were largely of the heavy variety and decidedly ill-suited to portability for use by rapidly advancing infantry troops.  Each weighed somewhere in the 30kg-60kg range - often without their mountings, carriages and supplies.

The Machine Gun in 1914

The 1914 machine gun, usually positioned on a flat tripod, would require a gun crew of four to six operators.  In theory they could fire 400-600 small-calibre rounds per minute, a figure that was to more than double by the war's end, with rounds fed via a fabric belt or a metal strip.
The reality however was that these early machine guns would rapidly overheat and become inoperative without the aid of cooling mechanisms; they were consequently fired in short rather than sustained bursts.  Cooling generally took one of two forms: water cooled and, increasingly as the war developed, air cooled.  Water jackets would provided for the former (which held around one gallon of liquid) and air vents would be built into the machine gun for the latter.
Water cooled machine guns would still overheat relatively quickly (sometimes within two minutes), with the consequence that large supplies of water would need to be on hand in the heat of a battle - and, when these ran out, it was not unknown for a machine gun crew to solve the problem by urinating into the jacket.
Russian machine gun teamWhether air or water cooled, machine guns still jammed frequently, especially in hot conditions or when used by inexperienced operators.
Consequently machine guns would often be grouped together to maintain a constant defensive position.
Estimates of their equivalent, accurate, rifle firepower varied, with some estimating a single machine gun to be worth as many as 60-100 rifles: a more consensual figure is around 80, still an impressively high figure.

British Army Rejection

High enough indeed to make the British army's dismissal of the potential worth of the device in the early 1900s all the more difficult to understand.  Hiram Maxim, who designed the machine gun which bore his name in 1884, first offered use of the machine to Britain.  Although rapid-firing weapons, such as the 0.50-inch calibre Gatling Gun (invented in 1862), existed many years prior to Maxim's invention, all required some form of manual intervention, e.g. hand cranking.
Unfortunately for Maxim the British army high command could see no real use for the oil-cooled machine gun he demonstrated to them in 1885; other officers even regarded the weapon as an improper form of warfare.
Not so the German army which quickly produced a version of Maxim's invention (the Maschinengewehr 08) in large quantities at a Spandau arsenal; by the time war broke out in August 1914 the Germans had 12,000 at their disposal, a number which eventually ballooned to 100,000.
In contrast the British and French had access to a mere few hundred equivalents when war began.

Simple Design

British machine gunners in captured German second line trench at CambraiIn designing his machine gun, Hiram Maxim utilised a simple concept.
The gas produced by the explosion of powder in each machine gun cartridge created a recoil which served to continuously operate the machine gun mechanism.  No external power was needed.  His initial design, which was water cooled and belt fed, allowed for a theoretical rate of fire of up to 600 rounds per minute (half that number in practice).  It was heavy however, weighing in at 62kg.

German Enthusiasm

As already noted the Germans quickly grasped the potential importance of machine guns on the battlefield.  From the outset the German army demonstrated the value of the machine gun by creating separate machine gun companies to support infantry battalions.
The British however did not create their Machine Gun Corps until October 1915; until this time the few machine guns available were attached in sections to individual battalions.  A mere two guns were allocated to each infantry battalion in 1914.

Superiority of Defensive Warfare Technology

When established in fixed strong-points sited specifically to cover potential enemy attack routes, the machine gun proved a fearsome defensive weapon.  Enemy infantry assaults upon such positions invariably proved highly costly.
Belgian machine gunners setting up in beet field near LebbekeThe French in particular found to their cost that the technology of defensive warfare was more advanced than that of offensive warfare.  The French pre-war military blueprint, Plan XVII, was founded upon a fundamental assumption of an 'offensive spirit', one which envisaged a rapid war of movement.
Early commanders, such as Charles Lanrezac, were dismissed for apparent failures in their implementation of the offensive spirit.  Time was to vindicate Lanrezac's doubts.
The British similarly found to their repeated cost the futility of massed infantry attacks against well-entrenched defensive positions protected by machine gun cover.  The first day of the Somme Offensive amply illustrated this, although the lesson appeared to be lost to the British high command.  On the opening day of the offensive the British suffered a record number of single day casualties, 60,000, the great majority lost under withering machine gun fire.

The Machine Gun as an Offensive Weapon

Understandably most historical accounts of the First World War have tended to emphasise the defensive strengths of the machine gun.  Throughout the war efforts were made to produce an infantry assault version, such as the Lewis Light Machine Gun, although these efforts were generally unsatisfactory.
Although lighter at around 12kg they were still considered too heavy and bulky for rapidly advancing infantry.  Attempts to transport light machine guns by wheeled carriages or pack animals were ultimately unsuccessful: the infantry invariably outpaced such methods.
By 1918 however one-man portable machine guns (including the formidable Bergmann MP18 submachine gun) were put to some use (each weighing 9-14kg), although maintaining sufficient ammunition supplies remained a difficulty.
German machine gun trenchAlthough often not truly portable light machine guns were more readily transported on roads or flat ground by armoured cars.
As the war developed machine guns were adapted for use on tanks on broken ground, particularly on the Western Front (where the majority of machine guns were deployed).
Light machine guns were adopted too for incorporation into aircraft from 1915 onwards, for example the Vickers, particularly with the German adoption of interrupter equipment, which enabled the pilot to fire the gun through the aircraft's propeller blades.
In response to the increasing success of machine guns mounted on aircraft it was perhaps inevitable that machine guns should similarly be developed as anti-aircraft devices (in France and Italy), sometimes mounted on vehicles.  Similarly machine guns began to be added to warships as a useful addition to naval armaments.

Magnesium: The Stress Reliever

Magnesium is the fourth most abundant mineral in your body, a necessary co-factor for hundreds of enzymes, and the most critical mineral of all for coping with stress. Stress-related diseases which run rampant through modern society, like heart attacks and high blood pressure, are often accompanied by magnesium deficiency. Unfortunately, most Americans consume diets that fail to meet the government's RDA for magnesium, and magnesium intake is even lower than average among people who develop heart disease. The best food sources of magnesium are vegetables like buckwheat (kasha), mature lima beans, navy beans, kidney beans, green beans, soy beans (including tofu), blackeyed peas, broccoli, spinach, Swiss chard, oats, whole barley, millet, bananas, blackberries, dates, dried figs, mangoes, watermelon, almonds, Brazil nuts, cashews, hazel nuts, shrimp, and tuna.
When you are chronically stressed, you can become magnesium deficient even if you eat these foods regularly. The complex relationship between magnesium and stress explains why many of the patients I see require magnesium supplements, because even a nutritious diet does not correct their magnesium deficiency.
If you are like most people, when you are exposed to the stress of contin-uous loud noise, for example, you become irrita-ble, easily fatigued and lose concentration. Your blood pressure may increase as the level of adrenalin, a stress hormone, in-creases in your blood. Under conditions of mental or physical stress, magnesium is released from your blood cells and goes into the blood plasma, from where it is excreted into the urine. Chronic stress depletes your body of magnesium. The more stressed you are, the greater the loss of magnesium. The lower your magnesium level to begin with, the more reactive to stress you become and the higher your level of adrenalin in stressful situations. Higher adrenalin causes greater loss of magnesium from cells. Administering magnesium as a nutritional supplement breaks this vicious cycle by raising blood magnesium levels and buffering the response to stress, building your resistance.
Personality has a marked effect on the stress-magnesium cycle. A study done in Paris found that stress-induced depletion of magnesium was much greater for people who show the "Type A", competitive, heart-disease prone behavior pattern than for their less competitive colleagues. Dr. Bella Altura, a physiologist at the State University of New York, has proposed that depletion of magnesium among Type A indiviudals is the main reason why Type A individuals are at increased risk of heart attacks.
It appears that the body's magnesium economy is an integral part of the stress response system. When stressed for any reason, the body's hormonal reponse causes an outpouring of magnesium from cells into plasma. This outpouring is a bit like taking magnesium by injection, except the source is internal. The effect of the sudden increase in magnesium is both energizing and calming. Magnesium is needed to burn sugar for energy; it also calms the excitation of cells produced by the stress-induced release of calcium. If there is insufficient dietary magnesium, or if there is insufficient rest in between episodes of stress, the body's magnesium stores are slowly depleted. The hormonal response to stress disintegrates. The plasma magnesium does not elevate in response to stress as it should, so that the energizing/calming effect of magnesium is not present to counter the nerve-jangling effects of adrenalin and other stress hormones. Consequently, the disorganizing effects of stress are intensified and coping is impaired. Higher blood pressure, abnormalities of your heartbeat and an increased risk of heart attacks or of angina (cardiac pain) may be one reult.

Beyond Insomnia: Your Favorite Sleep Hormone Is Now Used in Cancer Therapy

You probably know it as a supplement that can help you sleep or overcome jet lag. Certainly, this hormone has been used safely in small doses for dozens of years for these purposes. As numerous people — and I — can attest to, from 0.5 to 3 mg of melatonin taken half an hour before bedtime can turn a restless night into a restful one. And it can save you a day or more of fatigue if it's used before and after long plane rides. But melatonin does much more, especially in higher quantities. It’s being used to protect against cancer, and to enhance the effectiveness of cancer treatments.
This hormone regulates the patterns of wakefulness and sleepiness that coincide with light and darkness known as circadian rhythm. Melatonin levels should be highest at night and lowest during the day. But light shuts down your body’s production, so if you're in a well-lighted room late at night you may not be able to make enough melatonin to sleep well.
The melatonin/cancer connection
Exposure to light at night not only affects your ability to sleep during the day, it also increases your risk for cancer. Studies show that women who work late night shifts have an increased risk for getting breast cancer. And if you work late at night for just three nights a month over a period of 15 years, your risk for colon cancer escalates.
For a long time, we couldn't explain this phenomenon. Recently, however, a group of circadian-clock control genes were discovered that regulate the growth of normal cells and cancer cells. When these genes mutate, they cause a spontaneous outbreak of cancer. Why do they cause specific cancers? We don’t know yet.
Circadian rhythm organization
Cancer cells multiply at certain times of the day, so it stands to reason that cancer therapies should be timed with cancer cell growth. Yet, cancer treatments are given at times that are most convenient for doctors and patients — not at times when a hormone, nutrient, or medication would work the best. This just doesn’t make sense.
We have some studies that support giving cancer treatments according to circadian rhythms. One study showed that there was less toxicity and a better response from drug therapy in patients with colon cancer who were given their medication at night. Combine traditional treatments with melatonin, and the benefits increase dramatically. Let's take a look at some good studies on this subject.
A group of patients with advanced cancer were given 10 mg of melatonin at night for at least two months along with their other medications. They lost less weight and their disease progressed more slowly than those on the same therapy who didn’t take melatonin.
Melatonin added to prescribed medications was also associated with survival for more than a year in people with brain cancer, melanoma, lung cancer, and untreatable glioblastoma. The combination worked better than the medications alone.
But that's not all
Melatonin is an aromatase inhibitor. Aromatase means that it reduces the ability of male hormones (adrogens), such as testosterone, to turn into estrogens. This means that melatonin has anti-estrogenic effects. When you combine it with tamoxifen, it actually enhances tamoxifen’s effects. Melatonin also boosts the effectiveness of interferon on kidney cancers.
I'm particularly impressed with how this hormone protects healthy cells from toxins, such as chemotherapy, radiation, and other drugs. Perhaps this activity explains why it has proven to be so useful in people with untreatable cancers.
In several studies, there was less muscle wasting, less weakness, and a longer survival when patients were given 20 mg of melatonin at night along with either chemotherapy or supportive care.
What does this mean for you?
I'm not suggesting that you start taking high doses of melatonin even though there a number of supplement companies that sell it in 20 mg tablets. Melatonin is a hormone, and while I think that up to 3 mg a day is safe to take, I think that higher amounts should be monitored by your doctor, especially since there are interactions between melatonin and some pharmaceutical drugs. You don’t want the melatonin to increase the activity of other drugs without your doctor’s knowledge.
You might, however, show him or her this article and suggest they read some of the studies I've cited. Melatonin could be an appropriate nutrient to take for women who have hormone-related breast cancers, for people with inoperable cancers, and to protect you if you’re at a particularly high risk. This is a subject that's worth exploring.

10 Tips on Vacations and Your Health

1. Even the most spontaneous getaway needs some basic planning and preparation. If you are visiting a new place, or even one not so new, a good travel guide will give you information on things like available transportation, and the hours and prices of attractions. It should also include important phone numbers and places to get help in an emergency. Or find a friend who knows the area for some tips. Learn about what interests you, like the best hikes or restaurants. And enjoy the adventure of experiencing your own discoveries.
2. Put together a travel kit. Include some water, antibacterial soap, electrolyte and nutritional support (protein bars, supplements, and powdered nutrients that you can add to water), sunscreen, and first aid supplies. Obviously, if you are traveling by car, you can take more goods, such as extra snack/emergency food and water. When traveling by air, you?ll need to make your supplies more compact, but I always have water, a mini-flashlight, a few snacks such as a couple of apples and raw almonds, some simple first aid supplies, a variety of supplements and herbal remedies, and more. Yet, don?t overdo it as you?re likely to have to carry it all around.
3. Take care of your personal needs and of course, those of your traveling companions as well. Match activities with your energy and fitness level. Listen to your body. Give yourself the extra time needed to truly rest and relax. Let yourself sleep more than you do at home. Most of us are sleep deprived. Give yourself sufficient space to acclimate to changes in weather, altitude, or language.
4. Drink plenty of water; hydration is a key. This is especially important if you are visiting a place that is hotter or drier than your usual environment. Don't wait until you get thirsty to drink; you?re already dehydrated then (Review my June 2002 Tips for more on Water). Avoid beverages with added sugar, caffeine or alcohol, as these can contribute to dehydration. After exercise and sweating, drink a cup or two of water and add a pack of nutrients, such as Emergen-C (found in any health food store), or some replenishing electrolyte fluid.
5. Use sunscreen (natural is best) and remember to reapply after swimming or strenuous exercise. Invest in a natural sunscreen, one without many chemicals and that is more nourishing to the skin. If it?s really hot or you?ll be out very long, wear a hat. Also, in summertime, we can get quite dry, so applying some oils or lotions to our skin will nourish your cells and tissues and protect your skin.
6. Take appropriate safety precautions, especially when trying new activities. Things like elbow and kneepads, life vests, and other safety equipment can prevent accidents that truly can ruin your vacation enjoyment. Watch out for poison oak and ivy on hikes, check yourself and your kids for ticks after a hike, and have some protection against biting bugs or slithering snakes.
7. Avoid contaminated food or drinks, which are the major cause of stomach distress while traveling. This is especially true if you are traveling outside the US, but bad food and water can happen anywhere. To be safe, if it is not boiled, well cooked, or peeled, don't eat it. If you do fall victim to traveler's diarrhea, let your stomach rest and be sure to stay hydrated. Use probiotics (acidophilus and other healthy bacteria) both to prevent intestinal problems as well as to treat them. Some other GI protection can be gained by taking additional nutritional hydrochloric acid when you eat, which acidifies the digestive tract and reduces the ability for bad bugs to take hold. Digestive enzymes also help digest microbes to which we are exposed.
8. Know about your destination, at least the basics, before you get there. Don't keep money in a shoulder bag or obvious wallet. Exercise caution when using automatic teller machines and other places where you will be seen with cash. Be aware of your surroundings, and have an evacuation plan in case of emergencies. Also, learn about the best Foods where you are. Enjoy Nature?s bounty wherever you travel (in the US and Europe)?fresh seasonal fruits and vegetables at their organic best. Many cities have a downtown farmer?s market; ask the locals where they would go for the best and freshest foods.
9. Nutritional Supplements can be helpful. All the anti-oxidant nutrients are helpful for the stress of travel?vitamins C and E, beta-carotene, and selenium are the main ones. Others are alpha-lipoic acid, pycnogenol, and L-cysteine. I use B-vitamins as tablets or sublingual drops as well for balancing travel stress. Also, it may be helpful to have some spirulina or blue-green algae tablets for energy support. Store your supplements out of the sun or in the cooler. Herbs like Siberian ginseng may also help you deal with the stress of travel. When traveling across time zones, melatonin taken at your new bedtime can help reset your biologic time clock. Even low doses can be effective, so easy does it. Nutrient packets with extra B-vitamins and minerals are also very helpful for travel and exercise replenishment. Put a pack in your water.
10. Inner Healing & De-Stressing ? Prepare for the enjoyment of outdoors. Plan a fun trip of hiking, camping, playing at the river, or a few days resting at the ocean. Rekindling your Earth connection has benefits that last beyond this season, continuing to enrich the whole of your life. Relax and breathe. Enjoy yourself. Practice letting your stresses go, leaving them at home or the office when you?re on vacation. Find a great book to read on your trip. Get out in Nature. Be aware of vacation burnout, so build some time into every day for rest and replenishment. This might entail letting yourself just sit for awhile watching the clouds, the surf, listening to music, or reading a good book. Try being a wave or becoming the sky. I love an affirmation used for relaxation when I lie down, especially in a meadow, "My mind is the sky, and the clouds are my thoughts; I just watch them float by."

History of Firearms

Since the introduction of the flintlock musket in the 17th century, military small arms have gone through a series of significant changes.

Muskets

Puckle Gun - 1718
In 1718, James Puckle of London, England, demonstrated his new invention, the "Puckle Gun," a tripod-mounted, single-barreled flintlock gun fitted with a multishot revolving cylinder. This weapon fired nine shots per minute at a time when the standard soldier's musket could be loaded and fired but three times per minute. Puckle demonstrated two versions of the basic design. One weapon, intended for use against Christian enemies, fired conventional round bullets, while the second variant, designed to be used against the Muslim Turks, fired square bullets, which were believed to cause more severe and painful wounds than spherical projectiles. The "Puckle Gun" failed to attract investors and never achieved mass production or sales to the British armed forces. One newspaper of the period observed following the business venture's failure that "those are only wounded who hold shares therein." According to the Patent Office of the United Kingdom, "In the reign of Queen Anne, the law officers of the Crown established as a condition of patent that the inventor must in writing describe the invention and the manner in which it works." James Puckle's 1718 patent for a gun was one of the first to provide a description.

Revolvers

  • History of the Colt Revolver
    Samuel Colt invented the first revolver - named after its revolving cylinder. He was issued a U.S. patent in 1836 for the Colt firearm equipped with a revolving cylinder containing five or six bullets with an innovative cocking device. See also - Samuel Colt and the Revolver

Rifles

  • The breech-loading rifle was invented by Captain Patrick Ferguson of Pitfours, Scotland.
  • John Moses Browning - Winchester Rifle
    John Moses Browning was the prolific gun designer who invented the Winchester rifle (30/30), the pump shotgun, and the Colt 45 automatic. He is best known for his automatic pistols and was the first one to invent the slide, which encloses the barrel of a pistol and the firing mechanism.
  • John Moses Browning
  • Modern Assault Rifles - M16 History
    The history of the modern assault rifle begins with the German Sturmgewehr used during WW2, the first rifle that could fire a medium size bullet at high rates of fire. In response the U.S. military began developing their own assault rifle, the result was the M16 assault rifle, first issued to American Soldiers in Vietnam in 1968 and designed by Eugene Stoner, a Marine Corps Veteran.
  • John Garand - M1 Semiautomatic Rifle
    Canadian, John Garand invented the M1 semiautomatic rifle in 1934.
  • The Johnson Rifle
    The Johnson Model 1941 Rifle one of the most innovative rifles of its time period. The Johson rifle was invented by Melvin M. Johnson Jr.
  • Samuel Gardiner
    Samuel Gardiner, Jr. received a U.S. Patent in 1863 on a "high explosive rifle bullet" in .54, .58, and .69 calibers. Fused to explode 1 1/4 seconds after firing, it ensured that any soldier hit by the projectile with a range of 400 yards faced the danger of the bullet exploding within the impact wound. The U.S. Government purchased 110,000 rounds of such ammunition for issue during the Civil War. Criticizing the use of similar ammunition by the Confederates, General Ulysses S. Grant complained that "their use is barbarous because they produce increased suffering without any increased advantage to using them."
  • Rifle Scopes
    A rifle scope is a refractor telescope used on a rifle. In 1880, August Fiedler (Stronsdorf), forestry commissioner of Prince Reuss, managed to build the first telescopic sight that really did work.

Machine Guns

  • Gatling Gun - 1861
    Doctor Richard Gatling patented his design of the "Gatling Gun", a six-barreled weapon capable of firing a (then) phenomenal 200 rounds per minute.
  • Maxim Machine Gun - 1885
    In 1881, a friend of Hiram Maxim, the American inventor, told him: "If you wanted to make a lot of money, invent something that will enable these Europeans to cut each other's throats with. Hiram Maxim was born in Sangersville, Maine in 1840 and was the inventor of the Maxim Machine Gun and the Maxim Silencer.
  • Thompson Submachine Gun - Tommy Gun
    The Thompson submachine gun or Tommy gun was invented by General John T. Thompson, it was the first hand held machine gun. Thompson was driven with the thought of creating a hand held machinegun that would help end the First World War, However, "the first shipment of prototype guns destined for Europe arrived at the docks in New York city on November 11, 1918, the day the War ended."

KA-50 Black Shark

The KA-50 Black Shark (refered to by NATO as 'Hokum') is a sophisticated Russian-built attack helicopter that is in service in small numbers (8 actively deployed) with the Russian army.
The KA-50 is unusual for an attack helicopter in that it is crewed by a single pilot/gunner, making it a very demanding aircraft to fly and fight in. A two-seater version, the KA-52, has also been developed.

Whilst the MI-28N Havoc will be Russia's primary gunship, the KA-50 will carry out the role of Special Forces support.
KA50 BLACK SHARK FEATURES
  • contra-rotating co-axial rotors
  • zero-zero ejection seat
  • jam-proof laser designator for the Vikhr missiles
  • fire-control system shares target data with other KA-50s on the battlefield as well as compatible ground units
  • flare launchers for protection against IR-homing missiles
  • computer-assisted flight & navigation management system eases pilot workload
The Black Shark is designed to survive on the battlefield. The pilot is encased in armor designed to resist armor-penetrating rounds up to 12.7mm. The KA-50's rotors can take repeated hits from small arms fire. If the armor fails, a rocket-powered ejection system is installed for the pilot's emergency use.

The KA-50's double-stacked main rotor design eliminates the need for a tail rotor which makes the helicopter highly maneuverable at high speeds.
Armaments are fitted to hardpoints on two wings / pylons tipped with countermeasure pods. Up to 12 supersonic laser-guided vikhr anti-tank missiles can be carried, each with a range of 8km. A range of unguided rocket pods, mines and bomblets can also be fitted. The KA-50 carried a 30mm cannon beneath its nose. Firing either armor-piercing or explosive incendiary rounds, the 2A42 cannon can make short work of both armored and soft targets. Due to its contr-rotating stacked rotors, the KA-50 can point the weapon systems towards a target area whilst the helicopter continues moving along another axis. For this reason, the Black Shark's 30mm cannon only has a limited field of fire, unlike the turret-mounted guns on most other gunships.
The KA-50 has seen action against guerilla's in Chechnya,

History Of the Helicopter Gunship

Until the Vietnam conflict, military helicopters were mostly used for evacuating wounded troops. They were used extensively for this purpose doing the Korean War. Other roles included limited troop transport and observation.
The US involvement in Vietnam saw an increase in the use of helicopters as troop transports, often flying missions in which they came under heavy fire. The need for heavily armed helicopters soon became apparent. The Huey UH-1C troop transport was kitted out with machine guns and 2.75in FFAR rockets which were mounted on stub-wings attached to the chopper's fuselage. Other gunship configurations that were considered included modified CH-47 Chinooks (ACH-47s) armed with multiple guns, cannons, rockets and grenade launchers although these proved to be too cumbersome for use in the field.
In 1967 the US Army fielded that AH-1 Cobra, a dedicated gunship. Based around the UH-1 powerplant, the cobra had a much thinner profile, increased armor, speed and firepower. It proved to be highly effective in action against the NVA and Viet Cong.

The Soviets went through a similar evolution in their development of helicopter gunships as their US rivals. Starting with adding rockets and machine guns to MI-8 troop transports, they soon progressed to a dedicated design - the Mil MI-24 Hind. Both of these gunships would be used in many a battle in various third world conflicts, mostly in the infantry support role.
With the gunship concept now battle-proven, more advanced attack helicopters were developed in the late 70s/early 80s. The US fielded the Ah-64A Apache and upgraded AH-1 Cobras whilst the Italians developed the A129 Mangusta. These attack helicopters were designed with a confrontation with the Soviet Union in mind. It was hoped that their advanced avionics and anti-tank missiles would counteract the Warsaw Pact's overwhelming numeric superiority on the battlefield.
When the Soviet Union crumbled at the end of the 80s, the need for gunships may have been in doubt. 1991's Gulf War put any doubts to rest as fleets of Apaches and Cobras decimated Iraq armor in the open desert. Once again the concept had proven itself.
The terrorist attacks of September 11th, 2001 and the resulting war in Afghanistan took helicopter gunships into battle once again. The Apache, already proven in the anti-armor role now distinguished itself in the infantry support role as Coalition forces would frequently call the gunships in to attack Taleban forces.
The US-led invasion of Iraq in 2003 saw the Apache helicopter deployed once again although this time the battles were a little less one-sided as before. When the Apaches went into combat over populated areas with lots of cover for ground troops to lurk in they were less effective than when over the open desert. Coordinated ground fire downed or severely damaged several Apaches causing them to abort missions. Despite these setbacks, when deployed against Republican Guard divisions positioned out in the open, the Apaches once again proved to be a devestating weapons plafform.

In early 1980's British Army started the search for the replacement of the aging L42 Enfield sniper rifles. Main compettitors were british companies Parker-Hale with their Model 82 bolt action rifle, and Accuracy International, with their PM rifle. Eventually, PM rifle won the competition and was accepted by British Army under the designation of L96.
One of the most notorious features of the PM rifle was design of the stock. Instead of the solid polymer or wooden stock, PM / L96 rifle used hollow polymer stock, made from two halves and assembled around aluminium bedding block, that extends through entire stock lenght. L96 also was equipped with backup iron sights.
In mid-1980s Swedish armed forces began their own quest for the new sniper rifle, which could survive cold and harsh nordic environments. The AI again become the winner in this race with improved L96 design, named "Arctic Warfare". In 1988 Swedish forces adopted AW rifle in 7.62mm NATO chambering under the designation of PSG 90. British Army, in its turn, also adopted this improved design under the designation of L96A1, as well as many other militaries and Law Enforcement agencies around the world. In 1998, the Bundeswehr (Germany Army) also adopted the AW Super Magnum rifle chambered in .300 Winchester magnum (German caliber designation is 7.62x67mm) as Scharfschutzengewehre (sniper rifle - german) G22.

Built by Accuracy International of Portsmuth, England, this line of rifles is among the best in the World of sniper rifles today. This rifle can shot less than 2" (51mm) groups at the distances of 600 yards (550m), using boat-tail match ammunition. Arctic Warfare is a line of 5 rifles. Original Arctc Warfare was designed for the British military. It gained its designation by special anti-icing features, allowing sniping operations to be carried out under Arctic conditions as low as -40C (-104F)! Other models are Police (AWP), Suppressed (AWS), Folding (AWF) and Super Magnum (AW SM). Three first rifles designed for 7.62mm NATO ammunition, while Super Magnum can be chambered in .338 Lapua Magnum, .300 Winchester Magnum and 7mm Remington Magnum. AW has a 26" (660mm) barrel, AWP has 24" (609mm). AW SM barrels available in lentths from 24" (609mm) to 27" (686mm). The standart scopes supplied by Accuracy International are Smidt&Bender 3-12X variable or the Leupold Mark 4 fixed 10X scope
