			<content:encoded><![CDATA[<p>I had a moment of nostalgia today that reminded me of my childhood days. As I walked down the road in the snow, with baby son snuggled up against me in his baby-carrier and mum and grandma following close behind under their own respective umbrella&#8217;s, I found myself singing songs to the little one. I soon realised the songs I was humming were loading tunes for computer games that used to run on the 8 bit micro computers of the 1980&#8217;s, specially the Acorn BBC B Micro computer. Let me explain a little more, since many people reading this blog entry may not have a clue what I&#8217;m talking about, especially those who have grown up surrounded by modern games consoles and powerful desktop and laptop home computers. </p>
<p>These days, when you want to play a computer game on your desktop computer or console, you click an icon, wait a couple of seconds and the game fires up. Back in the 1980&#8217;s things were significantly different. Most home microcomputers did not have a hard disk. They loaded programmes off cassette tape. The tape player was usually connected via a data cable to the micro computer and if you loaded up a game you could hear the data being loaded in to the computer by turning up the sound on the cassette player. The whole process could take anywhere between a minute, for simple and short computer programmes to several minutes for more complex and data heavy applications, such as games. </p>
<p>To make the whole process of &#8220;watching paint dry&#8221; &#8211; which is what it sometimes felt like when loading up a game &#8211; many games coders would first load a graphical screen containing, for example, the logo of the game, and then load up an intro-tune. In other words, a piece of music that would play whilst you waited for the main game to load up. This would provide a little light entertainment. As games got bigger and better the tunes also got better and better. The BBC Micro computer, back in the 1980&#8217;s had a four channel audio system which basically allowed the computer to play up to four &#8220;instrumental sounds&#8221; at once. This was plenty enough to make for enjoyable tunes.  </p>
<p>What a stark contrast to today&#8217;s gaming experience. There&#8217;s a string of game loading tunes I remember fondly and often find myself humming either in my mind or more recently out loud to the little one.  </p>
<p>Here&#8217;s a great example of a game called Firetrack (one of my favourites) loading up on the BBC micro. Along with the loading tune, you can also hear the constant burring of the data being loaded in. </p>

<p>The other thing that comes back to mind is the classic Acornsoft logo which you&#8217;d often see displayed whilst a game would load off tape. Acornsoft was an early software publishing company producing games for the then popular BBC Micro computer which was in fact made by Acorn Computers Ltd. Here&#8217;s an example of the Acornsoft game loading screen for a game called Super Invaders:</p>
<p><object width="445" height="364"><param name="movie" value="http://www.youtube.com/v/AmOd33jXqWM&#038;hl=en_US&#038;fs=1&#038;border=1"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/AmOd33jXqWM&#038;hl=en_US&#038;fs=1&#038;border=1" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="445" height="364"></embed></object></p>
<p>The other really cool thing I remember about the BBC micro and other computers of its ilk back in the 1980&#8217;s was just how easy and enjoyable it was to create programs that would run on them by simply typing in a few lines of code. I remember how I would often walk in to a branch of Dixons, a then popular high street electronics store in the UK, and walk over to their computer section where they would have a BBC micro on display, force quit the shop demo that was running and then type by hand my own little graphics demo application. The code was written in an interpreted language called BBC BASIC and the program I&#8217;d most often write was the one where you could get random shapes to appear all over the screen in a never ending loop. Here&#8217;s a great little video showing just that (and a lot more):</p>
<p><object width="445" height="364"><param name="movie" value="http://www.youtube.com/v/nT8B8n3mIHo&#038;hl=en_US&#038;fs=1&#038;border=1"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/nT8B8n3mIHo&#038;hl=en_US&#038;fs=1&#038;border=1" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="445" height="364"></embed></object></p>
<p>Oh, the good old days. Then came along the 1990&#8217;s and the affordable spread and availability of hard disks built in to home computers. The late 80&#8217;s and early 90&#8217;s also hailed the advent of more powerful graphic user interfaces. I remember being a die hard Acorn computers advocate and back in the late 80&#8217;s and early 90&#8217;s Acorn had launched arguably one of the most advanced and powerful home computers based on their early RISC chip called the ARM processor. ARM processors are found, now-a-days embedded in almost every mobile computing device, most notably mobile phones. The power of the then new ARM chip enabled Acorn to launch there multi-tasking 32bit operating system called Risc OS (technically it was a 26 bit OS) which was capable of running games that utilised solid 3D graphics, a domain that was exclusively reserved for the more expensive and dedicated arcade games machines which you&#8217;d never find in a home. Zarch is the name of a game that came free with the Acorn Archimedes computers, the first RISC based home computer that Acorn produced back in the late 80&#8217;s and 90&#8217;s. Here&#8217;s a short video showing just how advanced things had already become back then, and we&#8217;re talking over twenty years ago.  You&#8217;ll also note from this video the WIMP interface of Acorn Computer&#8217;s RISC OS. WIMP stands for Windows Icon Mouse and Pointer. </p>
<p><object width="445" height="364"><param name="movie" value="http://www.youtube.com/v/tw94qXPfg6Y&#038;hl=en_US&#038;fs=1&#038;border=1"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/tw94qXPfg6Y&#038;hl=en_US&#038;fs=1&#038;border=1" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="445" height="364"></embed></object></p>
<p>My all time favourite computer game to this day has to be Elite. A 3D space trading and combat game. The basic idea of Elite was to pilot a space ship through several galaxies trading goods from planet to planet.  As you traded you would build up more cash reserves by selling your cargo for a profit and slowly upgrade your space ship with better armaments, more cargo carrying capacity and better shielding, etc. Along the way, you might get attacked by pirates who have scanned your ship inventory and want to rob you of your cargo. You would have to defend yourself against these marauders. You could also choose the path of a criminal and trade in illegal goods which would fetch greater profits, but at the risk of being brandished a fugitive and constantly attacked by police ships. Or you could be a pirate yourself and attack other space craft and scoop up their cargo to sell on for a profit. This was all played out in a full 360 degrees 3D space environment. To get an idea of the type of gaming experience you got in Elite, watch this short video of the game running on a 8 bit BBC micro computer:</p>
<p><object width="445" height="364"><param name="movie" value="http://www.youtube.com/v/ZEbhsXIL8a8&#038;hl=en_US&#038;fs=1&#038;border=1"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/ZEbhsXIL8a8&#038;hl=en_US&#038;fs=1&#038;border=1" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="445" height="364"></embed></object></p>
<p>Elite is no more, but it lives on in the form of <a href="http://www.oolite.org/">an open source clone called Oolite</a>, which runs on the Mac. Anyone on a Mac should definitely check this game out and give it a go. It&#8217;s faithful to the old game and even goes as far as preserving much of the graphical interface with options to enhance the graphics, the features and gaming scenarios. There&#8217;s a huge community of developers constantly updating the game and there&#8217;s a discussion forum available for avid fans of the old game. Oolite still posses great game play which I find many modern day games lack. </p>
<p>That&#8217;s it for my trip down memory lane, all sparked off by me humming tunes from game loading intro&#8217;s on the Acorn BBC Micro computer to my baby son.</p>

It usually the American&#8217;s, Japanese and Korean&#8217;s who are out there in front. Not so with music streaming service <a href="http://www.spotify.com/">Spotify</a>. Unless you&#8217;ve been living under a rock for the last year or so, you&#8217;ll know that Spotify is a great music streaming service that allows you to build and share your own play lists and almost instantly streaming high quality music over the internet to your PC and/or Mac.  However, the hordes of iPhone users have been rather ignored until recently. Spotify have been working on what appears to be an amazing Sporify iPhone application which will be available in the iPhone AppStore store very soon. </p>
<p>Here&#8217;s a great video demo of what&#8217;s soon to come. Check it out and leave your comments here.</p>

			<content:encoded><![CDATA[<p><div id="attachment_171" class="wp-caption alignleft" style="width: 210px"><img src="http://kaustav.uk.com/unisphere/wp-content/uploads/2009/05/virgin_media-300x257.jpg" alt="Virgin Media" title="virgin media" width="200" height="157" class="size-medium wp-image-171" /><p class="wp-caption-text">Virgin Media</p></div>I&#8217;ve been on an 8Mbps (downstream), 512Kbps (upstream) ADSL broadband connection now for over five years. It has served me well with little or no hiccups. However, recent changes to the way I work has required me to look for a faster broadband connection, especially one with a broader upstream speed of at least 1Mbps.</p>
<p>Enter Virgin Media with their triple pack which offers cables TV, phone and broadband all in one. The broadband service in my area offers 50Mb downstream and 1.5Mb upstream. Firstly, the deal is pretty good in terms of price. With my new Virgin Media set up I am paying on average £15/month less than what I was paying when I had two separate services; one for phone and broadband and another for satellite TV. </p>
<p>Virgin Media came around to install their service at my home today. I was greatly looking forward to the faster broadband service and interested to find out what sort of set top box I&#8217;d set for my TV service. Here&#8217;s a run down of what happened during installation. The installer laid in the cable from the junction box outside in to the house. He then discovered that he didn&#8217;t have a wireless router for me in his van and asked me if I had been sent one by Virgin Media&#8217;s customer services. Nope, nothing. The installer calls up a colleague in the local area and asks him if he has one in his van. No such luck. Installer proceeds with getting cable TV set up. Everything gets plugged in and TV is turned on. For some reason there&#8217;s no picture coming through. Therefore, we moves on to the third item which is phone. I&#8217;m told that because I want to keep my old number I won&#8217;t have a proper phone service from Virgin Media today as my old number still needs to be ported over. So far, nothing is working. The installer proceeds to install the cable modem and we try the connection out on my Macbook Pro.  As expected and predicted the installer gets rather nervous and worried that there&#8217;s a shinny Apple Mac in front of him. He proceeds to tell me to load Internet Explorer. Clearly he&#8217;s never used a Mac before. No worries, I tell him, I actually have Windows XP and Windows 7 installed on my Mac and that I could load Internet Explorer for him.  Since I have a web development background, I proceed with Firefox in Mac OS-X anyway and start stepping through the various initialization pages on the Virgin Media initial setup web site. It records my requested email ID, username and password. On the last page of set up there is a long pause as the modem reboots. Unfortunately the modem refuses to allow an open connection to the web even after restarting twice automatically and one after being restarted manually.  At this paint the installer gets on the phone to customer services. He is acting and sounding rather frustrated, and I don&#8217;t blame him. He&#8217;s on hold for 15 minutes, which appears to make him feel a little embarrassed. I would be too, if I was in his shoes! Eventually he gets through and describes the various issues to customer services. Within minutes my broadband is up and running. Apparently I was still behind the Virgin Media firewall and so my account way manually activated by the customer services person on the phone. OK, so next up is TV. Apparently there&#8217;s a delay at the headend for provisioning new customers and I&#8217;m told my TV service will be running within the hour. Fair dues. The missing wireless router will be sent to me in the post and I should receive it by tomorrow.  </p>
<p>Right, so I need to take another day off work to ensure I&#8217;m around to receive the package as it will undoubtedly not fit through the small letter box. If only it was all working today, but I guess that&#8217;s too much to ask for. I&#8217;d have expected at least the physical items to be all installed and working and the rest can no-doubt be configured remotely. </p>
<p>One hour later, my TV service is up and running. The modem is working, but I have to sit on the floor close to the TV where the modem sits and be hooked up via ethernet cable because I have no wireless router (which arrives tomorrow). I&#8217;ve still not got a phone service. I have to wait for my old number to be ported. At this point I do not know how long this will take and I suspect it will require a call to customer services, and no doubt a long wait on hold, to get that sorted out. </p>
<p>All in all, from a customer perspective, I&#8217;ve not had a very good first day with Virgin Media. No phone, no wireless. I suppose 50% of what I&#8217;m supposed to get is &#8220;good enough&#8221; for Virgin Media. </p>
<p>Ironically, Virgin Media picked up my excitement of about getting their 50Mb broadband service on Twitter and sent me a message which said &#8220;<strong>@virginmedia: @jupiterorbit Do let us know how it goes <img src='http://kaustav.uk.com/unisphere/wp-includes/images/smilies/icon_smile.gif' alt=':-)' class='wp-smiley' /> </strong>&#8220;. I&#8217;m afraid I had to tell them the truth and let them know that I wasn&#8217;t very impressed with their installation process.<br />
<div id="attachment_175" class="wp-caption center" style="width: 310px"><img src="http://kaustav.uk.com/unisphere/wp-content/uploads/2009/05/settopbox-samsung-smt-2110ca-300x146.jpg" alt="The Virgin Media Samsung set top box" title="settopbox-samsung-smt-2110ca" width="300" height="146" class="size-medium wp-image-175" /><p class="wp-caption-text">The Virgin Media set top box</p></div><br />
My final gripe is that the set top box I have got for my TV service has no analogue audio output although I did notice a digital SPDIF socket. This means I cannot hook up the set to box to my nice Cyrus amp. I&#8217;ll have to see if my TV has an audio out which I can hook up to my amps. The sound quality through the Cyrus system is vastly more superior to that of my TV. </p>
