			<content:encoded><![CDATA[<p>Well, as per my meta-goal <strong>101 – Do 100 day updates</strong>, here is the Day 200 update.</p>
<p>Not much movement really&#8230;.</p>
<p><strong>The Good:-</strong><br />
<strong>66 – <a href="http://en.wikipedia.org/wiki/Via_ferrata">Via Ferrata</a> in Italy</strong><br />
I go on Friday, cant wait.</p>
<p><strong>82 – Visit Egypt</strong><br />
I go in October for 2 weeks, 1 week cruise &#8211; 1 week sun and as much archaeology as I can get!</p>
<p><strong>94 – Go to Edinburgh festival</strong><br />
Will fly over for a weekend in Aug, let me know if you are interested in joining</p>
<p><strong>28 – Drive Offroad</strong><br />
Going back to Dubai in December when it cools off, will be driving a mates Hummer in the desert.</p>
<p><strong>75 – <a href="http://groups.csail.mit.edu/mac/classes/6.001/abelson-sussman-lectures/">Watch SICP,</a> do exercises from <a href="http://mitpress.mit.edu/sicp/">book</a></strong><br />
Did half when visiting Germany from Den Haag a few weeks ago, mind bending but wonderful stuff.</p>
<p><strong>72 – Read “<a href="http://en.wikipedia.org/wiki/Winning_Ways_for_your_Mathematical_Plays">Winning Ways</a>”</strong><br />
Inspired by <a href="http://en.wikipedia.org/wiki/Martin_Gardner">Martin Gardner</a>s death, I did half of the first book when I had some downtime in Manchester. First bit of new Maths in ages and it felt great. See <a href="http://www.msri.org/publications/books/Book29/contents.html">Games of No Chance</a> for more fun.</p>
<p><strong>8 – Read all the <a href="http://www.oup.co.uk/academic/series/vsi/vsiguides/">VSIs</a></strong><br />
Read Vikings, Human Prehistory, Memory, Archaeology, Evolution, maybe more &#8211; i need to get tactical and create a master list.</p>
<p><strong>13 – Release 303 books on bookcrossing.com</strong><br />
Tasked my long suffering mother with labeling them all, need to teach her how to register them then release them. Still need to sort out the <a href="http://www.bookcrossing.com/zones/promote">Crossing Zone</a> in Liverpool too.</p>
<p><strong>48 – Create a <a href="http://blog.backblaze.com/2009/09/01/petabytes-on-a-budget-how-to-build-cheap-cloud-storage/">backblaze storage pod</a></strong><br />
They are <a href="http://ukblazers.com/2010/06/08/updated-pod-design-sent-to-be-fabbed/">getting made soon</a>, due on the 28th</p>
<p><strong>The Bad:-</strong><br />
<strong>5 – Lose 2 stone</strong><br />
Got half way Jan/Feb, might have taken a step back living away again&#8230; Correctable though!</p>
<p><strong>19 – Blog on average once a week</strong><br />
Way off, need to blog furiously to catch up.</p>
<p><strong>The Almost Had:-</strong><br />
<strong>22 – Spend 3 months in another country</strong><br />
Spent two in Holland (Den Haag / The Hague) working for ING. </p>

			<content:encoded><![CDATA[<p>Well, it has been an interesting few months, in brief:</p>
<ul>
<li>Went to Libya to work for a big telco</li>
<li>Went to Oklahoma for a mates wedding then drove 2000 miles (or rather, made my girlfriend drive 2000 miles as I lost my driving licence&#8230;), visited 5 states and two national parks to see <a href="http://en.wikipedia.org/wiki/Ancient_Pueblo_Peoples">ancestral pueblo people</a> sites</li>
<li>Moved to Den Haag (The Hague) for 2 months to work on INGs Next-Gen data center</li>
<li>About to move to Camden for the next bit of work</li>
</ul>
<p>Not much movement on 101 goals, planned Egypt in October and <a href="http://en.wikipedia.org/wiki/Via_ferrata">Via Ferrata</a> next week. Behind on learning goals though have done half of <a href="http://mitpress.mit.edu/sicp/">SICP </a> in one mind bending train journey!</p>
<p>I kind of feel my life has been on hold the last 6 weeks I have been in Holland and am really looking forward to being back in the UK (though perhaps could have done with more of a break in between)</p>
<p>Expect more jollys to get planned before the end of the year (VMworld, Citrix Synergy, War Horse, Japan and Edinburgh all sounding fun at the moment), perhaps I&#8217;ll find time to blog about some of the cool shit at the NGDC and my US trip.</p>

			<content:encoded><![CDATA[<p>I was just over at a good friends in Leeds and mentioned my 101 goals and needing to tick some off and if he could help me make some jam sometime. </p>
<p>We got straight down to making lemon curd (not a jam, but my goals &#8211; my rules) and it was seriously yummer, recipe below.</p>
<p><strong>Lemon Curd</strong></p>
<p><em>4 medium-sized lemons<br />
100g (4oz) butter<br />
1/2kg (1lb) sugar<br />
4 beaten eggs<br />
</em></p>
<ul>
<li>Scrub Lemons, grate rinds, squeeze out juice
</li>
<li>Place juice and rind in double saucepan over low heat and slowly add sugar and butter.</li>
<li>Cook, stirring, until all the butter and sugar melt</li>
<li>Add eggs and cook, stirring, untill the curd is thick enough to coat a spoon.</li>
<li>Pour into small jars and seal with waxed disks or paraffin wax.</li>
<li>Cover and store in cupboard for one month, fridge for 3 months, freezer for 9 months.</li>

			<content:encoded><![CDATA[<p>The last two weekends I have traveled across to London from Faversham to see friends and visit a few museums.</p>
<p>During the weekend of 9/10th I met up with my sister in the British Museum and showed her around (one of my 101 goals ticked off in the process). I was very pleased to finally see the <a href="http://www.britishmuseum.org/explore/highlights/highlight_objects/me/t/the_flood_tablet.aspx">flood tablets</a> I had read about a lot (in brief &#8211; a pre-biblical flood narrative dating back to Sumeria that is part of the epic of Gilgamesh that the Genesis writers seem to have borrowed from). Also mid last year a metal-detectorist found the largest hoard of Anglo-Saxon gold ever found, it has been named &#8220;<a href="http://www.staffordshirehoard.org.uk/">The Staffordshire Horde</a>&#8221; and is on display there while they catalog it. </p>
<p>On the Sunday we went to the National Gallery and saw <a href="http://www.nationalgallery.org.uk/whats-on/exhibitions/the-sacred-made-real">The Sacred Made Real</a> a wonderful display of Spanish polychromatic wooden sculpture. It is the best exhibit I have seen in ages and finishes this weekend, go and see it if you can. It is interesting to see sculpture in colour as we are so used to classical and neo-classical sculpture being the very austere white. Interestingly greco-roman sculpture would originally have been painted anyway so the neo-classicists were harking back to something that never really existed. </p>
<p>The next weekend I stayed in Richmond for a friends birthday and we popped to the V&#038;A on saturday and well just wow. I only spent an hour there but it is amazing that London has (at least) 3 really world class museums, it is on par with the British Museum and the Metropolitan Museum Of Art &#8211; really fabulous, I will return soon.</p>
<p>On the Sunday I went and looked at the <a href="http://www.npg.org.uk:8080/beatles/exhib.htm">Beatles to Bowie</a> exhibition of 60&#8242;s photography, which was pretty good, then returned to Faversham.</p>
<p>All in all good fun in the greatest city in the world.</p>

			<content:encoded><![CDATA[<p>[edit]I have since set up a separate site as I have found a company in the UK to fabricate the cases and will be trialing different software stacks on top, please check out <a href="http://ukblazers.com">UKblazers</a>[/edit]</p>
<p>A while ago I saw the <a href="http://blog.backblaze.com/2009/09/01/petabytes-on-a-budget-how-to-build-cheap-cloud-storage/" target="_blank">Backblaze storage pod</a> and was impressed.</p>
<p><a href="http://www.thattommyhall.com/wp-content/uploads/2010/01/pod.jpg"><img class="alignnone size-medium wp-image-113" title="pod" src="http://www.thattommyhall.com/wp-content/uploads/2010/01/pod-300x221.jpg" alt="" width="300" height="221" /></a></p>
<p>Like many others I thought:</p>
<ul>
<li>I want one</li>
<li>Wouldn&#8217;t it work great with ZFS</li>
<li>The hardware sucks</li>
</ul>
<h3>Building one</h3>
<p>I used to make and sell storage servers using Linux a while ago with media streaming software and easy setup (before all the ready-rolled ones came out) so the software side is not a major challenge. Backblaze have released a template for the cases and a list of other components and coincidentally a good friend is a Mechanical Design Engineer and can work on it for me. The cost for the cases drops precipitously if you buy in bulk and he is looking at making it able to be stored flat and easily assembled by folding edges together so I will take the plunge and buy a load, if anyone wants to get hold of some, please get in touch.</p>
<h3>ZFS</h3>
<p>As soon as you see so many disks in a case like that, it&#8217;s hard not to think of Sun&#8217;s Thumper and ZFS.</p>
<p><a href="http://www.thattommyhall.com/wp-content/uploads/2010/01/X4540.jpg"><img class="alignnone size-medium wp-image-112" title="X4540" src="http://www.thattommyhall.com/wp-content/uploads/2010/01/X4540-300x165.jpg" alt="" width="300" height="165" /></a><a href="http://www.thattommyhall.com/wp-content/uploads/2010/01/k3_sunfire-x4540_5.jpg"><img class="alignnone size-medium wp-image-111" title="k3_sunfire-x4540_5" src="http://www.thattommyhall.com/wp-content/uploads/2010/01/k3_sunfire-x4540_5-300x239.jpg" alt="" width="176" height="140" /></a></p>
<p>I&#8217;ve <a href="http://www.thattommyhall.com/category/zfs/" target="_blank">blogged about ZFS</a> before and given talks on it. With so many disks to fail (either noisily or silently)  data loss is inevitable (and worse &#8211; you may not even be alerted), ZFS would solve this (or at least ensure you know about it). BackBlaze use custom application logic to work around this, using TomCat and HTTPS.</p>
<h3>It&#8217;s Not Highly Available</h3>
<p>A chap at Sun has a critique <a href="http://www.c0t0d0s0.org/archives/5899-Some-perspective-to-this-DIY-storage-server-mentioned-at-Storagemojo.html" target="_blank">here </a>that is totally spot on and he makes a few great points about subtle changes to Sun&#8217;s design to accommodate vibration, noise and electromagnetic radiation. In so many ways the hardware is inadequate and does not have the uptime characteristics of a device in Suns range. That said though an individual device from Sun is not as HA as, say, an EMC SAN (with mirrored write cache, dual SPs etc) as it too relies mostly on commodity hardware. For FiveNines availability you need to decide what you are doing to protect against device failure anyway, the BackBlaze devices just fail faster &#8211; that&#8217;s your trade-off.</p>
<h3>It wont be fast</h3>
<p>That is largely a feature of the disks and the controllers; you could get a better motherboard, disks and faster controllers, perhaps eschew the port multipliers too, if performance is a problem. A very cool new feature of ZFS (<a href="http://blogs.sun.com/brendan/entry/test" target="_blank">L2ARC</a> / <a href="http://blogs.sun.com/brendan/entry/hybrid_storage_pool_top_speeds" target="_blank">Hybrid Storage Pools</a>) allows for using SSD as a second level cache, that would help. In linux <a href="http://users.cis.fiu.edu/~zhaom/dmcache/index.html">dm-cache</a> (or <a href="http://kernelnewbies.org/KernelProjects/DmCache">here</a>)  could probably achieve something similar.</p>
<h3>How can you make it HA?</h3>
<p>This is really another blog (and a few weeks work hacking out the ideas), but I can think of several ways of doing what BackBlaze do in their software stack to export files (via NFS, SMB or other protocol) or block devices (ATAoE, iSCSI, NBD etc) in a robust manner.</p>

			<content:encoded><![CDATA[<p>I have decided on a kind of hyper-resolution for the new year, 101 goals in 1001 days.<br />
I have a mindmap of the ones I have settled on so far and have started working on some of them already.</p>
<p>To follow (allowing me to tick off some of the meta-goals):</p>
<p><em>Success criteria for each</em><br />
Divide them up into &#8220;Sustained Effort&#8221;, &#8220;1-off&#8221; and &#8220;Requires Break&#8221; to make sure I don&#8217;t overextend myself. I plan on taking roughly quarterly 1 or 2 week breaks to try and do these tasks. For the sustained ones I need progress metrics, am I on track to complete in the time given?</p>
<p><em>The actual 101 things!</em><br />
Need to settle on the actual 101 things, most are on there but it&#8217;s still a bit fluid.</p>

<p>As one of my goals is to blog more, you should be hearing more from me in 2010.</p>
