3.0 out of 5 stars Caution - does not strip cat6 properly, 25 Dec 2012
Verified Purchase(What is this?)
This is a good tool for cat5 cables, and is fine for crimping cat6 cables. However, the part of the tool which is designed to strip the outer cable is set too tightly for cat6 cables (they are bulkier because they contain a plastic inner core which keeps each of the twisted pairs separated). I did a number of test runs, and each time there was damage to the inner wires on cat6 cables, whereas cat5 cables stripped faultlessly.

5.0 out of 5 stars Good migration from ADSL to BT Infinity (edited 12/2012), 3 May 2011
Verified Purchase(What is this?)
I bought this to replace a Thomson speedtouch, because I wanted to upgrade to Wireless-N and also see if I could improve my ADSL2+ bandwidth.

The 'N' is obviously faster than my previous 'G' router, and the coverage is much better. My worst case wireless reception (a long way from the router, with a couple of solid walls between) improved from 26% to 45%.

Without making any changes, I saw an immediate improvement in broadband performance of about 15%. I wanted to squeeze the most out of my connection, and the router helps you to do this, if you are prepared to do some investigation and some tweaking. As others have advised, once you have the router installed, upgrade to the latest firmware (1.06c at time of writing). Next, go to the ADSL status page on your router and look at the Line Attenuation (Downstream). If you google for ADSL Theoretical speed calculator and plug in this value on the resulting page, you will be able to find the theoretical maximum attainable rate for your line. Based on my attenuation of 37.5, It told me that I was 2.7km from the exchange and the max rate I could achieve would be 13.1Mb/s. I asked my ISP to adjust the line, and they set the SNR margin to 6dB. I then set the SNR margin in the router to around 3.5, which is what seems to be recommended on the excellent whirlpool forum.

As a result, I have been able to increase my bandwidth from 6Mb/sec to 11.5 Mb/sec. So far I have received 146 MBytes of data without any errors or drops.

Although it seems expensive at first sight, I think that this router is good value for money.

EDIT: (Dec 2012) This has continued to work faultlessly on ADSL2+ for over 18 months. BT have recently introduced Infinity (80Mb/sec) into my area, so I upgraded. The Billion router has a EWAN port, which means that it can be reconfigured to replace the BT HomeHub 3.

Although the HH3 is not too bad, only one of its LAN ports runs at 1 gigabit/sec, and some people (myself included) are a little queasy about BT being able to make changes to the router from their side, and with the default HH3 settings which make part of your bandwidth available publicly as part of the BT wifi offering. The wireless range is also better on the Billion and if you have configured up dhcp ranges, port forwards, etc., these are retained. There have been some reports that wireless clients do not run at full speed - if so, removing the QoS settings from the configuration resolves this (for more info on this point, google is your friend).

If you want a good ADSL router, and may consider upgrading to Infinity at some point, then the Billion provides helpful future-proofing.

Please note that you still need to retain the BT OpenReach modem - you just swap the Billion for the HH3 box. If you want to eliminate the modem and just have a single box, then you will require a VDSL2 capable device, such as the Billion 8200N, Draytek 2750N, etc.

5.0 out of 5 stars A Tour de Force, 1 Dec 2009
Of the many books in my technical library, this one never fails to impress me. The quality of the writing, the thoroughness of coverage and the structuring of the book set a benchmark which many technical books struggle to meet.

A number of reviewers have pointed out that trying to learn the language from this text is difficult, and that it is best considered to be a reference guide. Experience with C, Java, Python or similar will help you to understand the syntax easily and this book will give you all that you need to become proficient in the language; if you do not have such experience, then an introductory text may be a good companion.

The book is divided into four main sections: "Core Javascript", "Client-Side Javascript", "Core Javascript Reference" and "Client-Side Javascript Reference". The client-side Javascript section gives good coverage of the DOM, CSS, Ajax and more; there is enough meat in here for you to start building demanding applications without recourse to additional texts (although you may want to buy specialist texts in these subjects over time). The table of contents is helpful, and each main section has its own mini table of contents. The book's indexer deserves credit: 43 pages of sensible indexing means that you can always find what you need. My advice to users of this book is to first spend an hour becoming familiar with its structure - knowing your way around will make subsequently finding things much easier, and will help you to enjoy and get the best from its nearly 1000 pages.

On the rare occasion when the depth of coverage is insufficient for a specific need, the book will have given you enough background for you to feel confident doing targeted googling for the extra information (iframes was a recent case in point for me).

This book is the only Javascript book which Douglas Crockford recommends - high praise indeed. Once you start to feel confident with the 'Definitive Guide', you may appreciate Crockford's book, and those of John Resig, as you find yourself being transported towards Javascript gurudom.

1.0 out of 5 stars Lamentable and annoying, 30 Nov 2009
This is a book which becomes increasingly annoying with each reading. The editorial team were either asleep or, more incredibly, actually share the five authors' facile sense of humour which strangles the text and patronises the reader.

The case studies introduce too much extraneous information and, for me, are unsuccessful; the points they address could have been made more succinctly without them. Building chapters around case studies makes it difficult to find the specific information subsequently - this is exacerbated by completely unhelpful entries in the table of contents (e.g. "A glimpse into a Classless Future (Not a Socialist Manifesto)" [drum roll, cymbal crash], or "Love your body Even More Tomorrow" [ho, ho]).

Instead of going into a second edition, Wrox press should have pulped any stockpiled copies and fired this team of jokers.

I would recommend prospective purchasers to avoid this book like the plague; there are better books which cover CSS more professionally and thoroughly.

It is not possible to give a rating of zero stars, so please do not take my 1* rating as any kind of commendation.
