TapSonos from Scratch

2 Jan 2010 15:46 by Rick

Perhaps you have seen a Sonos system in someone’s house or you have seen it in hi-fi shops or on the internet and fancy one yourself. The advertising says you can get it going with one click (or is it two?) and it really is that easy but like any new acquisition it is worth doing a little planning first.

I will assume that you have an existing hi-fi system, a collection of CDs (music on Vinyl and Tape is beyond the scope of this article), a computer (Windows or Mac, desktop or laptop) and a broadband connection (this is essential) but not necessarily a wireless network. I will NOT assume that you are an iPod/portable MP3 player user—if you are then it can be easier (or can be harder!) This is written for a UK audience but most parts will be applicable elsewhere. Before we start, lets talk about budget. Over a complete system you need to allow about £500 per room. The first ones will be a little dearer and money can be saved by using existing components such as loud-speakers but it won’t alter the bottom line by a lot.

The first thing to decide is where you want to listen to music. There is no problem in starting small and expanding later but it can be cost effective to do two rooms at a time. In the room where the hi-fi sits you will need a ZP90 (ZonePlayer) connected to a spare input on your amplifier or receiver with the cables provided. These sockets could be marked Aux, AV (or even Radio or Video) but Phono inputs are not suitable. For rooms with no existing hi-fi then a ZP120 which has a built in amplifier can be used with a pair of loudspeakers and cable. Expect to spend £100–£200 for a pair of speakers as you will want decent ones, and try listening to some before buying as these affect the perceived quality more than anything else. I have no experience of the Sonos own-brand speakers. For less critical environments such as the kitchen, cheaper speakers can be used or the new Sonos S5 system which is semi-portable and has built in speakers (it only needs a mains power connection.)

One of the Sonos units must be hard wired to your broadband router! If you want music near where this is located you can use a standard ZonePlayer and connect that. If not then a cheaper option is to use a ZoneBridge (ZB100) which just makes the necessary network connection. All the equipment, except loudspeakers, can be hidden away in cupboards so long as they have adequate ventilation. In exceptional houses (very thick walls, large floor area or more than two stories) then you will need to carefully consider the siting of the equipment. A good rule of thumb is to make sure that each device is within 10m horizontally or 3m vertically from another one towards the direction of the hard-wired component. People with pre-wired houses have tried putting all the ZonePlayers in one cupboard but this can make it difficult to get a good signal on the wireless controllers.

You control the system to select the music to play using the hand held wireless controllers. You will probably need at least one. Each controller has a charging station (thankfully now included in the box) where it sits ready to be used. We have a three story house so keep one on each level. In addition there is a free computer desktop controller (PC or Mac) which it is worth installing as it makes system maintenance easier, but you probably won’t want to use it for day to day operation. There is also a well advertised controller application for the iPhone/iPod Touch. This requires you to have a (separate) wi-fi wireless system on your home network (the 3G Internet on the iPhone is not an alternative) and can be a cheaper substitute for the portable controller (free if you already have the device) but does have drawbacks e.g. it takes a while to wake up. Note that the Sonos system does NOT play the music that is on your iPod.

This has all been straight forward so far but now we come to the stuff they don’t talk about in the adverts. Sonos is well designed for non-technical users but here we need to get a little bit geeky so it runs smoothly long-term. Primarily, the Sonos plays music from digital storage i.e. Computer hard drives. The easiest and cheapest option is to use the music library facilities on your home computer—Windows Media Player on a PC or iTunes on a Mac. However this does have significant drawbacks, the most obvious of which is that the computer needs to be switched on to play any music. Home computers are not designed to be on all day, every day. They are not reliable enough, there are security implications and the power consumption can be considerable.

A better alternative is to use a NAS (Network Attached Storage) device. This is not a Music Server or anything fancy, just a box with hard drives attached to your network. It is designed to be on all the time and usually has power saving features to go into a standby mode when not in use. Talk to your supplier to find a suitable device – in technical language you want one that does SMB file sharing. I use the Netgear ReadyNas Duo which has two hard drives that mirror each other—i.e. they have identical copies of the same data so that if one fails you don’t lose anything. This guards against most failures except theft—if that is an issue or you have irreplaceable material then I would suggest a separate secured or offline backup system – discuss this with an expert. The NAS device wires to your router in the same way that your computer and the first Sonos system, with a Network cable.

What file format should you use? The four well known alternatives are WMA (Windows Media Audio), m4a (Apple format), FLAC (Lossless) and MP3. Sonos will play any of them but the first two can limit your future choice of other devices such as portable players. Purists like the lossless format but I can never hear the difference and they are supported by fewer systems so I would suggest using the MP3 format as it is very flexible. All the formats (except FLAC) can be recorded at different bit-rates; the higher the bit-rate the better the quality. As disk space is relatively cheap then go for the highest available. It used to be that people used lower bit-rates for portable devices but even these have massive capacity now so there is no need to compromise. There are two other formats you may have considered; WAV is supported by Sonos but it it is very wasteful of disk space for no benefit over other lossless formats and m4p files are the old Apple copyright protected files – they won’t play on Sonos and need to be converted to the liberated version (for a fee). There are other more obscure formats but if you need these then ask an expert.

How much storage space are you going to need? As a guide, my library has 10,000 tracks and takes up 70GB of storage using the highest quality MP3 files. The Sonos is limited to 65,000 tracks so I will never need more than 0.5TB. I bought 1TB drives because they were good value and I also use the space for PC backups. Using a lossless format I would need about three times the space.

To get the music off your CDs and onto the NAS (called “ripping”) you will need some software . This can be the same software that manages your library i.e. keeps all the information such as titles, artists correct. These programs also do things like a music jukebox but you won’t be using these facilities. If you have a Windows PC then I do NOT recommend using Windows Media Player. I have found that it has a mind of its own arbitrarily changing things that you have previously set. It has a time lag putting some operations into the background so unless you have it on a lot, some things never get done. The final nail in the coffin was that it always leaves a small gap between tracks even if there isn’t one on the CD. I have found the free MediaMonkey is a good alternative which does exactly what you tell it to. If you are a Mac user then people successfully use iTunes. It has some of the same problems as WMP, particularly with cover-art but I don’t know of a good alternative. There are available some separate and specialised CD rippers which are independent of the library managers—examples are Exact Audio Copy (EAC) for PC and Max (for Mac). These go to extraordinary lengths to guarantee that the copy you get is identical to what was on the CD. Whatever you use, take some time to get to know your program and discover how to set the recording format and quality.

When it comes to indexing your music, Sonos only takes account of six of the tags, as the information fields are called: (Album) Artist, Contributing Artist, Album (Title), Track (Name), Genre & Composer (these may have different names in your library software). All others are ignored and the last two are only used for indexing. It makes everything easier to find if you are consistent in using these—a task that is quite a challenge for the classical music lover and one that I haven’t yet completely solved.

Now you are all set but where should you buy it from? There is very little discounting for Sonos equipment so for cost it makes very little difference. You can buy direct from Sonos and it can be cheaper to get one of the bundles which include two ZonePlayers and a Controller. There are specialist online suppliers such as Simply Sonos who do a wider range of packages and deals. If you need to talk about loudspeakers and perhaps listen to some then many quality high-street hi-fi shops stock the range. I do not recommend buying the stuff on eBay unless you know exactly what you are doing. Some of it, even if new, is sourced from other countries and may have warranty implications.

Finally, sit back and listen. It will transform your music experience like it has mine.

TapThe last cheque is in the post

17 Dec 2009 10:17 by Rick

I have written before about why cheques should not be allowed to die and yesterday there was an announcement that they are to be phased out by 2018. They say “but only if adequate alternatives are developed” but by what and whose criteria? The committee is mostly made up of bankers and we all know whose interests they will be looking after.

We were wondering, while walking across the downs last night, if it is actually possible for cheques to be discontinued. After all, a cheque is only a signed letter from you to your bank to make a transfer; either to a named individual if the cheque is crossed or in cash to bearer. The banks issue fancy forms pre-printed with your name, account number and other details but you don’t have to use them. As A. P. Herbert demonstrated, a cheque can be written on anything so long as it contains the essential ingredients—information to identify the account (the bank and account name or number), validation of authority to make the transaction (signature) an amount, a date and a payee.

Of course you can take this a step further and remember that bank notes are only a specialised form of cheque. It is a letter from the chief cashier of the Bank of England at the time to credit you with a certain sum of money. When invented this meant gold but I am not exactly sure what it means now.

Footnote: it is also funny to notice that bank notes now have a copyright notice “©The governor and company of the Bank of England 2000.” Not only is that unnecessary as there are other laws forbidding uttering (forgery) but copyright law doesn’t even need it. Perhaps it is to dissuade Johnny Foreigner from photocopying a stash.

TapThe Hidden Internet

27 Nov 2009 13:35 by Rick

A friend pointed out the recent article in the Guardian about the dark side of the internet. Whilst it is quite a good article it both only just skims the surface and rather heavily emphasizes the negative aspects as if it was all deliberate and malicious. Here I will provide some definitions and separate out the completely different aspects of the internet that cannot be seen. Much of this is in the original article but it is overshadowed by a little journalistic hyperbole. I have also added some reference links, something newspapers always leave out.

Dark Internet

This phrase is used to describe the hard to access parts of the internet using any protocol. This could be caused by router configuration or firewalls. MILNET is a notable deliberate example, kept separate for obvious reasons. The majority of corporate and domestic computer networks also fall into this category either by the use of deliberate managed firewalls or simple NAT based routers with limited port forwarding configured. Another proportion consists of machines that people have forgotten about and are still running but the connections are damaged in some way.

Deep Web

There are Web sites that are hard to find by conventional search. This could be because of dynamic content,
lack of incoming links, registration/login requirements, deliberate banning of search bots, scripted links and non-indexable media formats such as audio, video and images. This limits their presence in standard search engines so cannot be found by conventional means. It is considered to be many orders of magnitude larger than the surface web indexed by search engines. To a limited extent this has been addressed by human based searches such as StumbleUpon, manual submission to search engines like Open Directory and semi-automatic systems using things like Google Sitemap. That is assuming, of course, that the owners want them to be found. The majority of this information is proprietary information accessible only by companies and their customers and academic data used by researchers. Also there are old web sites, abandoned and unloved that simply don’t work any more and can’t be indexed. Think Geocities or Tripod. It may also contain a small amount of content that some may regard as illegal. The reason it is likely to be small is that it requires a more stable, permanent and sophisticated infrastructure than underground organisations can sustain and, in any case, the external port is publicly visible.

Darknet

This is where the author started. They are network connections using protocols other than HTTP, usually for private P2P file sharing but can also support forum and chat type connections. The best known are Waste (by Nullsoft) [now withdrawn] and Freenet and form a very small proportion of the internet. These networks are often hosted on what would normally be regarded as personal desktop machines rather than centralised servers and form a rapidly and dynamically changing mesh as machines come and go. In this respect it is similar to other P2P systems but no files exist in one place in their entirety, they are fragmented and scattered. The services are founded on principles of free speech which may be beyond what some people would regard as legal or moral. There is no central organisation and therefore no censorship of any kind. A proportion of the material on the darknet would be regarded as illegal by some governments. This ranges from dissident material placed and accessed by citizens of repressive regimes, through music and video file sharing in contravention of copyright up to illegal pornographic material and terrorist aids. It should remembered that free speech facilities are used to do good as well as evil (put those two in whichever order pleases you) and it should be noted that Google is one of the largesst sponsors of Freenet.

The latter systems should not be confused with archaic protocol networks from the early days of computing which are still running. These include Fidonet, Compuserve, IRC and Usenet (sometimes called Newsgroups). They require specialised software to access them but are only dark because they have dropped out of mainstream usage. One could say that modern but proprietary protocols such as AIM, MSN & Skype fit this category but they are well known and don’t generally hold permanent content.

TapDedication

26 Nov 2009 16:51 by Rick

I have just been listening to an episode of Open Book (BBC Radio 4) in the car on the way home and they were talking about the dedications you find in most books before the preface and how revealing they can be. A very public expression of often very private thoughts. I was reminded that a book hat I have just finished had something similar, yet different. The novel “Fatal Voyage” by Kathy Reichs has quite a normal dedication but the copyright is assigned to ©2001 Temperance Brennan L.P. Unless you know her books you may not realise, but Tempe Brennan is the principal character in a lot of these novels so what is the author saying here—and, if it came to a dispute, could the copyright be upheld?

TapBeware the Facebook Bikini Girl

24 Nov 2009 08:48 by Rick

This is one for the boys—not. We have discovered that it is mostly the girls who are caught up by the Farmville type scams but this time it is the boys using Facebook that have to look out. There is a very sophisticated worm about (a worm is like a virus but crawls through web sites rather than directly between PCs). If you see someone’s profile picture has become a rather curvaceous girl in a Bikini then *don’t* click on it. If you do, then three things will happen. First you will be taken to a web site which contains rather a lot of porn. Secondly, that web site will download a lot of nasty stuff to your computer such as programs that steal account details. Thirdly, your profile will be changed to include this picture so as to attract other mugs victims. I said sophisticated at the start because it uses a lot of different techniques to trap you, from the initial social engineering making you think with the wrong part of your body through to clickjacking which is a page layout technique where you think you are clicking on something innocent (ha!) but actually saying yes to something important hidden underneath. As Roger Thompson says in a parody of Trooper Truth, “Keep safe, folks.”

TapA Disgrace to Parliament

23 Nov 2009 09:24 by Rick

It is looking likely that at the next general election, whenever it is called but certainly before next June, that the current government will be deposed and Her Majesty’s Loyal Opposition will take over. It is therefore with dismay that I heard this offensive speech from a member who is likely to become a minister under that administration. I refer to a passage in which Michael Grove, Shadow Secretary of State for Children, Schools and Families, managed in one short paragraph (last paragraph) to offend a member of the public not associated with the debate and also to indulge in a form of humour which may be mildly amusing in a playground. Perhaps that is why his brief is for schools. Of course we knew what to expect when here he made a “joke” on the Secretary of State’s name—the lowest form of wit by any standards.

TapThe Record Industry is Hurting

16 Nov 2009 13:33 by Rick

When you hear the frequent reports in the last few years about how file sharing has killed the music industry it all looks rather grim for the artists. This is particularly noticeable when major artists like Metallica and Lily Allen make the case rather than just the industry associations bleating about it. But are they mistaken and just puppets of the record companies; certainly in the early days of their contract their position must seemed rather precarious, subject to the whims of the promoter and woe betide them if they stepped out of line.

On the other hand there have been many critics of the record industry, such as Roger McGuinn, who have said that it is an unfair game often leaving the artists with nothing at all or in debt. As Lily points out, it is the band that pays for the studio, production, video, marketing and promotion and they have to refund this back to the record company out of their 15% of the royalties (if they are lucky). The advance they get is just to keep them alive.

This recent analysis by Times Labs shows that the majority of income for an artist is live performance (and I think it applies for the smaller venues as well as the stadium shows) and that has been steadily increasing even over the period supposedly hit by illegal downloading. As you will have seen from the Lily Allen article, some major artists believe that downloads often serve as tasters—samplers for the artist’s work—and that real income comes from later business. I don’t begrudge the artists any of this. An artist on tour works incredibly hard often at the cost of their health and relationships. I’m still glad I turned down the offer to do it some years ago.

I am not condoning pirating, particularly not wholesale music file sharing, but for sampling it does no more harm than a radio show. That it why I am very pleased that services like LastFM and Spotify allow it to be done legitimately. I have had reasonable success with my efforts to “Go Straight” which I did because I felt that I had rather overstayed my sampler welcome, by nearly 40 years in some cases, and the records I had recorded were often the best ones even though I had made some amends by buying follow up albums. Of course, by now, my efforts are more often benefiting the charity shops as they are mostly out of production.

I would certainly be sad if CDs disappeared off the shelves and everything went to iTunes and other commercial downloads, as I like something tangible for my money and convertable to other formats but I can see that the whole industry needs a shake up even if the record companies can’t.

TapTypical Farmville scam

12 Nov 2009 12:14 by Rick

If you are not aware of it, Farmville is one of the many addictive games that are available in Facebook. It is not the only culprit in these deceptive marketing techniques but among the best known. What you also need to know is that the lure is the internal currency used in the game. There is a thriving market in this to rival some minor real world currencies. For those that refuse to part with actual cash to buy the stuff then they try these sub-games.

Take the Farm IQ Quiz! test your knowledge of farming with the Farm IQ Quiz! How much do you really know about crops and farms? Take the quiz and find out today! No credit card needed to receive Farm Cash withing minutes.

At the end it says “Farm Cash awarded after the submission of a valid mobile number and PIN confirmation.” What they don’t say anywhere obvious is that sending this PIN number back to them as “confirmation” subscribes you to a mobile service which will cost you $9.99 US per month (there may be different versions in the UK). This is only one variation that makes Farmville and its associates part of a multi-million dollar business and as a side effect, the advertising boots the profits of Facebook. They don’t have the muscle to stop it but, when there is this benefit, why should they bother.

Thanks to SunBelt for the lead and TechCrunch for the detail.

TapCold Call PC repair

10 Nov 2009 12:33 by Rick

I just had a “Help desk” call from a friend who relayed a phone call he had received earlier this morning. The caller knew his name and address (and obviously his phone number) and then went on to say that his PC was running slow and was having problems and they could fix it for him. To demonstrate they asked him to open Start==>Run and type “eventvwr” which would open a window, then click on “System” and he would see a lot of yellow triangle warnings and red cross errors which showed that there were problems. They then said that they could fix it remotely but the conversation never got far enough to say how as he became too suspicious.

On further questioning, during which he was passed between three different people, he discovered that the company was called SupportOnClick in India at www.supportonclick.com and could be reached at a UK number in Bradford 01274 900834. This looks like a legitimate web site for a PC support company which works in America, Britain, Australia and NZ and I suspect that the next stage of the call would be a connection via Remote Desktop and they would do something innocuous and then try to sell you a contract for three years.

I don’t suspect that this was a criminal scam, either obtaining personal bank details or infecting your PC with malware but the methods are certainly deceptive—the mechanism they used to “demonstrate” that there were problems will always show some errors. It is useful for diagnosing problems but not worrying of itself. I suspect that they are just working down an electoral roll or some other mailing list; the majority of people they call will have a PC these days. Doing a web search I find that some people are not so lenient and, as they seem to use other deceptions like passing themselves off as from Microsoft or your ISP then perhaps it is more sinister and they are trying to sell bogus AntiVirus software after all.
