Can someone say "DREAM RIFLE"? My personally favorite sniper rifle is the Parker-Hale M85, but the WA2000 sure ranks up there on my wish list, and there is probably no other rifle that conjures up imaginations like the WA2000. This rifle was designed from the ground up as a sniper rifle, it is not an adaptation from an existing rifle. No expenses were spared in the design and construction of the WA2000, which may have been what ultimately doomed the rifle. The retail cost when new (in the 80's) was $12,500. The .300 was choosen as the primary caliber because of its long range accuracy and its consistancy at all ranges. The entire rifle is designed around the barrel. The adjustable trigger operates a hammer, and the entire firing machanism can be removed as a unit from the lower frame. The bullpup configuration allows a compact design while still maintaining a 26" barrel. The US Army M24 has a 24" barrel and is over 7" longer. The WA2000 fires from a closed bolt and uses a bolt with 7 locking lugs. Only 72 total rifles were produced in 2 different variants of which there were only approximately 15 imported into the USA.


The first model had problems with the gas blowback system and was soon revamped to the series 2. The 2nd generation (series) was refined with a more robust gas system which also reduced the recoil and a more effective flash hider was added in adition to an upgraded bi-pod. The fluted barrel was also eliminated on the series 2 rifles. The combination of the new gas system and the non fluted barrel made the second generation rifles more accurate than the first generation. The only fault I have with the weapon is its heavy weight. At 16 lbs its really getting up there. Accuracy is exceptional. Its easiest to tell the two variants apart by the two different flash suppressors. The "can" type flash suppressor is on the first generation, and the more traditional flash suppressor is of the 2nd gen. The 2nd gen rifles incorporated several changes to make the rifle more suited to its intended job. Even if its heavy, the WA2000 is still an amazing rifle as both a sniper rifle, and a piece of art, current value of these rifles range from $30,000 - $40,000


Update!! Wait! The plot thickens! I received this email from a reader:


"On August 24, or today, I actually talked with Earl J. Sheehan, Jr., President of Carl Walther here in the U.S. I thought you guys could use a little more info on the gun so here it is. The rifle was produced from the late 70's though November 1988. The final retail cost for a base rifle in 1988 was in the range of $9,000 not $12, 500 like you have written on your page. He said the price never went that high while in production. That document that you have must be extremely old because there were more than 72 produced. Earl told me that there were precisely 176 WA2000's produced total. He also told me that there are only 15 units in the U.S., and that he owns 11 of them, and only one other party owns the other 4. The most amazing thing to me having this conversation though was that he offered me one of the rifles to purchase. He offered me one NIB (new in box) for approximately $75,000! YIKES! Any ways I saw that this was your dream rifle, thought I'd let you know that you can still get one from the guys at www.carlwalther.com if you have a spare 75k sitting around."


There you have it... some more interesting information to add to the mystery known as the WA2000.

Cara membobol password Deep Freeze

Deep Freeze adalah salah satu program "pengaman" yang paling populer di warnet. Program ini memang cukup powerfull dalam menghadapi virus maupun tingkah laku usil pengunjung warnet. Apapun perubahan yang dilakukan oleh virus maupun pengunjung akan dikembalikan seperti kondisi semula oleh DF.

Sayangnya karena terlena oleh kemudahan ini, beberapa admin warnet kadang jadi lupa dengan password DF, akibatnya admin kebingungan ketika hendak menginstall program baru karena program tersebut akan ditendang lagi oleh Deep Freeze.

Berikut ini salah satu cara untuk mereset / membobol password DeepFreeze yang sudah dicoba dengan DF 5 dan DF 6.

Berikut ini salah satu cara untuk mereset password DeepFreeze yang sudah saya coba dengan DF 5 dan DF 6.

Untuk DF 5 :

1. Install Df di kompie lain yang tidak terproteksi dengan DF. Set passwordnya sesuka anda. Agar saat ini rekan-rekan dengan saya, kita anggap saja password barunya adalah "bakmi"(tanpa tanda kutip).

2.Untuk DF 5, password DF tersebut disimpan di file bernama Persi0.sys yang terletak di drive C

Cara mereset passwordnya logikanya lumayan gampang seh : Kita replace saja file persi0.sys lama yang passwordnya kita lupa dengan file persi0.sys baru yang tentu saja passwordnya kita tahu karena baru saja kita buat.

3. hanya saja sampe saat ini proses mereplace ini setahu saya ternyata nggak gampang-gampang amat karena belum ada yang bisa melakukan dalam normal windows. (Bagi rekan-rekan yang tahu caranya silakan memberi masukan ). File persi0.sys tidak mau ditindih dengan file persi0.sys baru dalam normal wondows karena terproteksi oleh DF yang sedang berjalan.

4. Karena file persi0.sys tidak bisa diganggu gugat dalam normal windows maka kita terpaksa mencari cara lain. Anda bisa mencoba memakai sistem operasi lain, sistem operasi portabel, dan sebagainya untuk mereplace file persi0.sys. Tetapi saya pribadi cukup puas dengan memakai Recovery Consol milik Windows XP Prof Edition.

5. Anggap saja kita memakai CD Windows XP Professional untuk masuk DOS versi XP(Recovery Console Windows XP). Restart komputer. Set BIOS untuk boot lewat CD. Tekan enter untuk masuk CD Windows. Tunggu sampai muncul tulisan Windows XP Professional Setup. Muncul 3 pilihan : To Setup Windows XP Now, press Enter ; To repair a Windows XP installation using Recovery Console, press R ; To quit setup without installing Windows XP, press F3. Pilih/tekan R (to repair) untuk masuk ke dalam Recovery Console.

6. Isikan password admin anda. Bila dulu saat anda menginstall, tidak memasang password, tinggal tekan enter. Muncul prompt : C:Windows>

7.Copi file Persi0.sys dengan nama lain. Karena file Persi0.sys menyimpan password Bakmi, maka pada contoh ini file persi0.sys saya copi menjadi Bakmi.sys.

C:Windows> cd c: ---- pindah direktori ke C:

C:>copy persi0.sys Bakmi.sys ---- copi persi0.sys dengan nama lain

C:>exit ---- keluar

8. Masuk windows normal, copikan file Bakmi.sys di komputer teman anda tersebut ke dalam CD atau USB.

9. Selanjutnya masuk komputer anda yang DeepFreeze-nya terpassword. Copikan file bakmi.sys yang sudah anda buat ke dalam drive yang tidak diproteksi oleh DeepFreeze. Bila drive C diproteksi oleh DeepFreeze maka jangan masukkan bakmi.sys ke drive C, karena file ini akan dihapus oleh DeepFreeze. Anggap saja kita kopikan bakmi.sys ke drive D. Windows Recovery Console seperti cara sebelumnya. Rename file persi0.sys dengan nama lain. Copikan file bakmi.sys di drive D menjadi persi0.sys di drive C.

C:Windows>cd c: ----- pindah direktori

C:>ren persi0.sys Cp_persi0.sys ----- rename persi0.sys dengan nama lain

C:>copy d:Bakmi.sys c:persi0.sys ----- copy file baru menjadi persi0.sys

C:>exit

10. Masuk Windows, Masuk program DeepFreeze(konfigurasi) : Tekan Ctrl+Shift pada keyboard sambil mengklik icon DeepFreeze di Taskbar. Muncul kotak password. Isikan dengan password yang baru saja anda buat yaitu : Bakmi. Anda sudah bisa masuk file konfigurasi, tanpa perlu menginstall ulang DeepFreeze.Tanpa perlu install ulang windows.

Catatan :

Bila anda melakukan cara yang lebih ekstrim, seperti menghapus/merename file persi0.sys tanpa menggantikannya dengan file lain maka ada resiko system menjadi tidak stabil atau icon DeepFreeze-nya malah hilang dari Taskbar.

Ide-ide di atas bisa anda coba, bila DeepFreeze anda mengalami kerusakan sehingga meskipun anda ingat passwordnya tetapi program DeepFreeze itu sendiri hilang lenyap tidak tampak di Taskbar dan tidak bisa dipanggil. Kemungkinan besar ada file yang corrupt, bisa jadi file tersebut adalah file persi0.sys. Coba lakukan cara yang sama.

Untuk Deep Freeze versi 6 :

Caranya persis sama dengan Deep Freeze versi 5. Hanya saja untuk versi tertentu namanya lain yaitu $persi0.sys. Jadi kalau untuk DF versi 5 yang harus anda replace adalah file persi0.sys untuk DF versi 6 file yang harus anda replace adalah $persi0.sys (ada tambahan tanda dollar di depan).

Lha cara mereplacenya tentunya suka-suka anda, mau pake Linux, mau pake DOS, pake sistem oparasi portabel ya terserah situlah. Pada contoh ini saya cukup memanfaatkan Recovery Consolnya XP saja, karena nggak merasa butuh program lain.

Cara mudah Menjebol Password Deep Freeze 6

Melengkapi Tulisan Mengatasi Lupa Password Deepfreeze , sesuai dengan dinamika dan perkembangan jaman - banyak tips dan tools baru bermunculan ternyata :) termasuk juga untuk teknik untuk menjebol password Deep Freeze. Jika sebelumnya ada unfreezer untuk Deepfreeze 5 tetapi reset password harus dilakukan secara manual untuk Deepfreeze 6, maka sekarang ini beberapa tools penjebol password bahkan sudah bisa dipake untuk mereset password Deep Freeze versi 6

Kalau anda admin warnet dan sebangsanya, saya sarankan anda mengikuti perkembangan ini, karena tools ini benar-benar lumayan mengerikan. Bahkan kesan saya malah lebih mak nyus dari Unfreezer untuk DF 5.

Ada dua tools setidaknya setahu saya yang bisa dipakai untuk menjebol password DF 6 nyaris dengan seketika tanpa perlu susah payah. Ngeri deh :(

TOOLS PERTAMA bernama Anti Deepfreeze, kelihatannya karya programmer Arab.

Tampilannya seperti ini :

Cara menggunakannya sangat mudah, Tinggal pilih versi Deepfreeze lalu klik tombol Apply. Kemudian klik gambar icon Deepfreeze di taskbar ( Ctrl + Shift ) sambil klik icon . Jika ada kotak password biarkan kosong, langsung masuk saja. Anda akan dibiarkan masuk konfigurasi Deepfreeze tanpa password

TOOLS KEDUA bernama Uninstall Deepfreeze, karya programmer Vietnam. Kalo program sebelumnya pake bahasa Inggris , program yang ini berbahasa Vietnam.

Tampilannya seperti ini : 

Cara memakainya juga mudah meskipun berbahasa Vietnam, klik tombol Login, sampai tombol Login tidak aktif dan tombol Crack berubah menjadi aktif. Kemudian klik tombol Crack. Langkah selanjutnya sama. Masuk ke file konfigurasi DeepFreeze dengan Ctrl+ Shift + klik icon DF atau cara lain. Bila ada kotak password abaikan, langsung masuk saja.

Semua cara ini dilakukan di Normal Windows, tetapi memang butuh restart komputer.
Sekali lagi, karena potensi dua tools ini agak tidak mengenakkan buat admin warnet cs, saya himbau rekan2 admin lebih memperhatikan masalah ini dengan menambah proteksi DF dengan tools yang lain. Meskipun memang yang namanya program apapun tetap ada kemungkinan ditembus passwordnya.

=================================================================

Download dua tools tersebut di sini 

Gunakanlah alat bantu ini dengan bijaksana.

Bukan cuma admin, user warnet juga sebaiknya berhati-hati karena aneka script, program aneh-aneh bisa dimasukkan oleh siapa saja di warnet-warnet. Alamax daku sendiri bisa ikutan pusing kalo main di warnet. :(

SALAM

How to Make Your PC Safe for 2012

How to Make Your PC Safe for 2012

New malware is still being introduced at an alarming rate: Alone in the last five years it has been rising by about 5,000 %. Such growth rates may be any shareholder's dream at the moment but here they are evidence of the immense profitability of the hacker industry. Your personal data, online connections or even access to your PC make the cash registers ring. This makes developing increasingly sophisticated and less easily detected ways to infect your PC more and more lucrative for clever programmers. But there is no need to panic, as we are going to show you in this article how to avoid unnecessary risks and how to keep on surfing the web with your PC safely in 2012!

1 - Keep Your System up-to-date

We all know that update notifications can be annoying. Still, your PC and all installed programs should always be up-to-date. Malware programmers often use newly discovered software weaknesses (so-called "vulnerabilities") to smuggle their malware onto your PC via exploits. Therefore, update your software on a regular basis - especially if it is widely used - in order to close potential security gaps as soon as possible. The following software on your PC should always be kept up-to-date:

• OS (Windows operating system)
• Your browser: MS Internet Explorer, Firefox, Chrome, Opera, etc.
• Adobe Acrobat Reader
• Adobe Flash Player
• Java Runtime
• Apple Quicktime Video Player
• Your media player (VLC, iTunes, Windows Media Player)

2 - Use Secure Passwords

Your PC may be as secure as a safe, but that is useless if an unauthorized person gets their hands on the keys. No matter whether it is your Windows login, web mail or password to a website: use only secure passwords! A secure password consists of at least eight characters and contains a number, an uppercase letter and a special character, such as "ApL47bAk!". Avoid common words like names and use different passwords for all your accounts and connections. If you use one password for all, a hacker gains access to all your data by just cracking one password successfully. To keep track of several passwords, we recommend using a password manager.

3 - Use a Router

It is common nowadays for internet connection packages to include a router. A router enables several devices to simultaneously use the same internet connection. Securitywise, this is a huge advantage as your PC does not directly connect to the web, which makes it difficult to directly address and attack it. If, for whatever reason, you still do not have a router, you should consider it a good investment. The same rules apply here: always keep the router up-to-date, that is, regular firmware updates and a secure admin password are a necessity.

4 - Avoid File Sharing Websites

Apart from the fact that they are mostly offering illegal content, file sharing websites are among the most common sources for malware infections. Cracked programs or so-called key generators ("keygens") in particular are often infected with malware. It is safer to download original software from the manufacturer's website or from well-known download sites.

5 - Use Restricted User Accounts

Many Windows users are using the administrator account. As an administrator, you have unrestricted access to modifying important system settings, which allows malware executed as an administrator to settle and spread with ease. If you have Windows XP you should use an account with restricted user rights for working and browsing the web. Windows Vista and 7 come with a built-in and redesigned User Account Control (UAC). Any process likely to cause damage to or be a threat to the security of your system needs the administrator's permission to do so. Never grant administrator rights to any unknown or suspicious programs!

6 - Avoid Doubtful Websites and E-mail Attachments

Today, most malware is spread via so-called "drive-by downloads". Modern websites are using different technologies to enable the continuous communication between your browser and the web server without asking you, the user, for confirmation. Programmers of criminal websites rely on this technology to take advantage of security gaps in various browsers. We recommend staying away from any doubtful or shady websites (file sharing, warez and erotic websites in particular) and to keep your browser up-to-date as described in point 1.
E-mail attachments are still the most popular way of spreading malware. What helps best is a good spam filter. Always remain skeptic if you receive e-mails from unknown senders and pay particular attention to any attachments before opening them; executable files like .exe or .com are often disguised as documents or images. For more information on this topic and fake e-mails please refer to our article Current E-mail traps.

7 - Beware of Unsecured WiFi Hotspots

There are many WiFi hotspots free of charge available that allow you to check your e-mails and surf the internet when you are on the go using your laptop or smartphone. But whenever you log into a website or check your e-mails via an unsecured WiFi connection, others can read your log-in data. Send confidential data only if it is absolutely necessary, and even then only over a secure connection! You recognize a secure connection by the "s" which directly follows the typical "http" in the address bar, i.e. "https://" (Hypertext Transfer Protocol Secure). This applies to online banking as well as forums, webmail accounts, ebay or Facebook log-ins - i.e. it applies generally for any log-in. If you use an e-mail client, you should also enable secure log-in in the settings.

8 - Use Security Software With Real-Time Protection

By following our advice you are already quite safe - but there will always be a small risk remaining. This is why we recommend the use of anti-virus software and a firewall. The anti-virus software checks files on your PC whereas a firewall monitors any incoming and outgoing connections. If there are any suspicious processes, a message will pop up to warn you about the risk.
Both programs should offer real-time protection. Regular scans with a virus scanner are good and important. However, they can only detect already existing infections with malware on your PC and may not always be able to remove them. Emsisoft behavior analysis, for instance, is always active and works similar to your body's immune system: suspicious intruders will be recognized even if there are no antibodies (= virus signatures) yet. By the way, Emsisoft Internet Security Pack contains Emsisoft Anti-Malware, a state-of-the-art virus scanner with behavior analysis and a file guard, and the powerful Emsisoft Online Armor Firewall. This means quadruple protection for your PC and therefore safety in 2012 as well.

How Do I Make My Computer Safe From Viruses and Hackers?

Lock Down Your Internet PC!

If you subscribe to Cable or DSL broadband at home, then you are likely to be casually "attacked" by hackers up to three dozen times a day. Especially if you use Windows XP or other Windows operating systems, you are a prime target for savvy hackers who will exploit your fulltime Internet connection.

As good as Microsoft products are, they are also obsessively targeted by hackers around the world. Small Microsoft "holes" perforate your computer, including: your administrator account, your ICF firewall service, your guest logon, your shared folders, your messaging services, your Identifier Broadcasts, your port openings, and your Encrypted File Services... all of these obscure points are absolute candy for hackers!

Yes, this is frightening. But all is not lost... most of these security holes in Microsoft are easily patched by an hour of reading and an hour of configuring your PC.

Good home security is about vigilance, knowledge, and meticulous attention to detail. We here at About.com want to help you with that, so we have provided dozens of free articles explaining security holes and how best to plug them.

Welcome to the exciting and challenging world of anti-hacker and anti-virus defense! What follows next are explanations of firewalls, packet filter routers, toggling Windows services to prevent external access, configuring WiFi networks for privacy, and overall blocking of hackers on Cable and DSL networks.

Smoke Bomb Materials

Photo of burning homemade smoke powder.

Timo Halén

The smoke bomb you would purchase from a fireworks store usually is made from potassium chlorate (KClO₃ - oxidizer), sugar (sucrose or dextrin - fuel), sodium bicarbonate (otherwise known as baking soda - to moderate the rate of the reaction and keep it from getting too hot), and a powdered organic dye (for colored smoke). When a commercial smoke bomb is burned, the reaction makes white smoke and the heat evaporates the organic dye. Commercial smoke bombs have small holes through which the smoke and dye are ejected, to create a jet of finely dispersed particles. Crafting this type of smoke bomb is beyond most of us, but you can make an effective smoke bomb quite easily. There are even colorants you can add if you want to make colored smoke. Let's start out with instructions for the easiest/safest type of smoke bomb you can make:

Smoke Bomb Materials

• sugar (sucrose or table sugar)
• potassium nitrate, KNO₃, also known as saltpeter (buy it online or you can find this at some garden supply stores in the fertilizer section, some pharmacies carry it too)
• skillet or pan
• aluminum foil

Once you've gathered your smoke bomb materials, it's easy to make the smoke bomb...

1. Pour about 3 parts potassium nitrate to 2 parts sugar into the skillet (5:3 ratio is also good). Measurements don't need to be exact, but you want more KNO₃ than sugar. For example, you can use 1-1/2 cups KNO₃ and 1 cup sugar. If you use equal amounts of KNO₃ and sugar, your smoke bomb will be harder to light and will burn more slowly. As you approach the 5:3 KNO₃:sugar ratio, you get a smoke bomb that burns more quickly.
   
2. Apply low heat to the pan. Stir the mixture with a spoon using long strokes. If you see the grains of sugar starting to melt along the edges where you are stirring, remove the pan from the heat and reduce the temperature before continuing.
   
3. Basically you are carmelizing sugar. The mixture will melt and become a caramel or chocolate color. Continue heating/stirring until the ingredients are liquefied. Remove from heat.
   
4. Pour the liquid onto a piece of foil. You can pour a smaller amount onto a separate piece, to test the batch. You can pour the smoke bomb into any shape, onto an object, or into a mold. The shape and size will affect the burning pattern.
   
5. If you aren't going to clean your skillet immediately, pour hot water into the pan to dissolve the sugar (or else it will be harder to clean). Clean up any residue you may have spilled out of the pan, unless you want mini-smoke bombs on your stovetop.
   
6. Allow the smoke bomb to cool, then you can peel it off the foil.

Now that you've made your smoke bomb, it's time to light it...

How to Use a Smoke Bomb

It's easy to make your own smoke bomb using potassium nitrate and sugar.

Anne Helmenstine

The solid smoke bomb material is flammable and can be lit directly. You can light your smoke bomb using a lighter, preferably one of the long-handled types used for barbeque grills. Only light your smoke bomb in a well-ventilated area, on a surface that won't catch fire. The smoke bomb will burn vigorously (more slowly with a higher percentage of sugar) with a purple flame.

Alternatively, you could place a short length of fuse into the smoke bomb when you pour it, and then light the fuse.

I have a smoke bomb video which shows this tutorial in action, plus what you can expect when you light the smoke bomb. You can adapt the smoke bomb recipe to make a homemade fountain firework, plus there are additional recipes for smoke bombs...

Additional Smoke Bomb Recipes

No-Cook Smoke Bomb or Powdered Smoke Bomb

A variation on the saltpeter/sugar recipe is to replace the granulated sugar with powdered sugar (icing sugar). The powdered sugar and potassium nitrate are sifted or mixed together and left in powdered form. The powder is ignited to form smoke.

Zinc & Sulfur Smoke Bomb

• Zinc Filings - Zinc Powder
• Sulfur Powder

Mix the zinc and sulfur. Insert a red-hot wire to ignite the mixture and produce smoke. This is a particularly smelly smoke bomb.

Black Powder Smoke Bombs

Black powder (gunpowder) or pyrodex can be mixed with other substances to produce a lot of smoke:

• as a powder, mixed with sugar and sulfur
• mixed with sawdust
• with sugar, sulfur, and a bit of material from a road flare (red flame)

It's easy to make a colored smoke bomb...

Make Colored Smoke Bombs

This is a purple smoke grenade, used during a military training exercise. The typical colored smoke bomb is like a normal white smoke bomb, with a dye released into the smoke.

U.S. Air Force photo/Tech. Sgt. Scott T. Sturkol)

The recipes for colored smoke bombs require chemicals that may not be readily available unless you have access to a chemistry lab, but it's worth knowing how it's done. Parts or percents are by weight. The ingredients are sifted together and ignited to produce the smoke.

White Smoke Recipe

• Potassium nitrate - 4 parts
• Charcoal - 5 parts
• Sulfur - 10 parts
• Wood dust - 3 parts

Red Smoke Recipe

• Potassium chlorate - 15%
• para-nitroaniline red - 65%
• Lactose - 20%

Green Smoke Recipe

• Synthetic indigo - 26%
• Auramine (yellow) - 15%
• Potassium chlorate - 35%
• Lactose - 26%

Reference: The formulations for colored smoke bombs came from Wouter's Practical Pyrotechnics, who cited the recipes as originating from L.P. Edel, "Mengen en Roeren", 2nd edition (1936).

You can also make a smoke bomb with colored flames...

White Smoke Bomb with Colored Flames

It's fairly easy to make colored flames by adding these chemicals to your smoke bomb recipe:

Chemicals Used to Color Flames

1. Red - strontium salts, most easily found in road flares
2. Orange - calcium chloride (laundry bleaching agent)
3. Yellow - sodium nitrate (common in chemistry lab)
4. Green - barium salts, such as barium nitrate (common in chemistry lab)
5. Greenish-Blue - copper sulfate (common in a chemistry lab, also found in many algicides for pool treatment) Blue - copper chloride (common in chemistry lab)
6. Purple - potassium permanganate (common in a chemistry lab, also used in sewage or water treatment)
7. White - magnesium sulfate (epsom salts, found on laundry aisle or in a pharmacy)

Essentially, you are adding metal salts to get colored flames. You may get additional ideas from looking at the Flame Tests, Fireworks Colors, and How to Color Fire tables. The metal salts listed here produce a relatively safe smoke. Use caution when considering other metals salts, as some compounds may produce toxic smoke.
