BÁc lazy làm gì con uTorrent mà tốc độ lên khủng khiếp thế. Em được có 1.5 - 2.5 kB

1- Giới thiệu:
Newsgroups là một bộ phận khá đặc biệt của NET, nó ra đời còn trước cả WWW vài năm. Lúc đó Internet chỉ được hiểu với vài cái máy tính nối với nhau, tức là còn rất trẻ. Khi đó có một hình thức chia xẻ thông tin là post các message lên các bulletin board (kiểu như forum bây giờ). Mỗi một hệ thông bulletin đó được một máy tính lưu trữ gọi là news server, còn các nhóm post message được gọi là newsgoups. Sau đó nhờ sự phát triển của Internet mà các news server này được kết nối với nhau và trao đổi các message (miễn là họ có thông tin về news group đó). Khi Internet cực thịnh thì hình thức post messages này thoái trào nhưng một sáng kiến tuyệt vời ra đời: dùng để truyền tải file giữa các server và giữa server với người dùng NET.
Nhưng một vấn đề lại nảy sinh, các news server chỉ truyền vả nhận các message, sao có thể nhận các binary file. Một sáng kiến nữa: chuyển binary sang text để gửi, sau đó bạn dùng một chương trình nhận các text đó và chuyển ngược lại thành file binary bạn cần (news reader).
2- News server: đây là các máy tính chứa các text message. Nói về các news server hiện nay thì đặc điểm lớn nhất là chúng phải có HDD cực lớn để chứa các text message. Song chả có cái ổ cứng nào là vô hạn cả nên có 2 khái niệm liên quan tới news server là retention (sự lưu lại) và completion (sự hoàn thiện)
Retention có thể hiểu nôm na là khoảng thời gian mà news server giữ một message trước khi xóa. Retention của từng news server là khác nhau, ổ cứng càng to thì retention càng lớn. Retention đối với từng news groups cũng khác nhau: alt.binaries.sounds.mp3.classical với 100 bài một ngày thì dài hơn alt.binaries.sounds.mp3.complete_cd với 1000 bài một ngày.
Completion: Như các bạn biết là để gửi file trên NET, người ta thường nén rồi cắt nhỏ chúng (sử dụng Winrar), mỗi một file rar đó lại bị cắt ra thành các text message (<10000 dòng), ví dụ một file 15MB thì bị cắt thành 7 text message. Khi đó nảy sinh vấn đề là có những file mà news server chưa nhận được đủ các text message đó hoặc đã bị xóa do quá retention. Khi đó chúng ta phải đợi news server lấy từ groups hoặc server khác, hoặc sử dụng file PAR/PAR2 (file kiểm tra chẵn lẻ). Completion biểu thị sự nguyên vẹn file, càng cao thì file đó càng gần gốc, 100% tức là đã có hết các text message.
3- News Reader: là các chương trình nhận text message và chuyển thành binary file. Có rất nhiều chương trình, nhưng thông dụng nhất là News Leecher (http://www.newsleecher.com/) và Grabit (http://www.shemes.com/)
4- News Groups: được đặt tên theo chuẩn (cấu trúc cây) như alt.binaries.movies>>alt.binaries.movies.xvid
alt.binaries.movies>>alt.binaries.movies.dvd....

A premium usenet provider. Unlimited account is very good. The limited account gives you access to their web based newsreader. The
unlimited account does not. The limited accounts are on a different server than the unlimited farm, so you may have better quality
bandwidth on the limited account also.
Completion (99%) and retention are both great (45 days). Good download speeds. Very reliable usenet service.

EASYNEWS
Best metered account and Web interface

Hostname: news.easynews.com

One of the best, they have it all!
The web interface is a real benefit-The global search of Easynews outperforms every other
binary usenet search system - The thumbnails rwill help you see if it is even what you wanted - A zip manager
You can earn free downloads with surveys and using the grid program(cancer esearch), and their web interface is one of the very best.
Too expensive to use as prime newsserver if you''re doing a lot of downloading but very good as a fill serve.

A reliable usenet service. The price is reasonable and the support is great. Good download speed.P.S: The amount downloaded is not limited, only the bandwidth available do download.
Currently the thresholds for bandwidth throttling is set at 150GB and 200GB usage for a calendar month. The first threshold at 150GB will slow the speed
down to 2Mbps if all allowed 8 connections are used. (256kbps per connection.)
The second threshold lowers the total bandwidth to 256kbps.

Một số link tham khảo:
1- http://www.slyck.com/ng.php?page=1: khái niệm về newsgroups
2- http://www.alt-bin.com: site để request các post đã bị xóa. Tích hợp cả IRC trên WEB.
3- http://www.angelfire.com/gundam/newsgroupguide/: hướng dẫn từ A-->Z download bằng NewReader, cách sửa file bằng QuickPar,cách nhận biết Retention, cách filling và request hiệu quả,....
Chú giải:
1- Unlimited Account: không bị giới hạn dung lượng download
2- Metered Account: hết dung lượng thì xin mời bỏ tiền thêm
3- Reseller: mua lại bandwith của các news-servers và bán cho người dùng cuối
4- Binary file: file nhị phân, đại khái là các file không phải text mà đã được mã hóa theo header của nó.

1- Thế download kiểu Newsgroups này hơn bittorrent ở điểm nào vậy bạn?
- Ưu điểm lớn nhất là bạn không có phải up cái gì lên cả, tốc độ luôn fullspeed nhưng nhiều khi cũng hay bị corrupt hơn bittorent vì không có cơ chế kiểm tra hash. Những file mới được các group release nhanh hơn cả bittorrent. Nhược điểm lớn nhất là phải trả tiền
2- Thế muốn tìm server của ISP thì làm thế nào?
- Bạn lên site của ISP. Ví dụ như mình dùng Mega Style thì lên fpt.vn, tìm từ khóa nntp, hoặc gọi lên số chăm sóc khách hàng của họ mà hỏi.
3- Retention cần lâu làm gì vì mình chỉ cần down về máy thôi mà?
- Nếu một file bạn search của một newgroup nào đó nhưng completion trên news server bằng 0 thì bạn buộc phải đợi server connect với group hoặc các server khác và tải các text message đó về. Vậy đó. Giờ nếu có các text message bạn cần thì chỉ việc down thôi, đỡ mất công đợi. Thường thì đồ mới completion luôn là 100%. Retention càng cao thì bạn càng có cơ hội down file có completion 100%.

Anh cũng đang dùng Mega Kotex như Lazyblackmage, dùng Emule và UTorrent chỉ được buổi tối là ngon thôi chứ sáng ra cầy cục được chục KB. Chắc các source đi ngủ hết rồi.
Nói chung nếu mà tranh thủ được ở VP chạy Mega VNN gói 1 triệu là tốt nhất, ngày nào cũng phải ít nhất 1 - 2GB.
