			<content:encoded><![CDATA[<p>Tonite at <a href="http://www.imug.org/">IMUG</a>, <a href="http://www.commonsenseadvisory.com/blogs.aspx">Rebecca Ray</a> from <a href="http://www.commonsenseadvisory.com/">Common Sense Advisory</a> talked about &#8220;Translation Performance Metrics.&#8221;</p>
<p>Translation cost is minuscule compared to the revenue it enables: less than 1% for most companies.</p>
<p>Centralized groups have fastest turnaround-time at 24 days, vs. average of 30 days for other groups.</p>
<p>5 or less FTEs do 60% of the work. A lot of outsourcing.</p>
<p>Word counts are going down, but some is moving to audio/video.</p>
<p>2/3 of projects are using more than 11 languages now!</p>
<p>(My feeling is that we&#8217;re going over 10 languages just because last decade we did 10, and now we do a few more languages  each year. Only Google has said, &#8220;We&#8217;re going  to support 99% of the users on earth in their native language.&#8221;)</p>
<p>Maybe ask the customer what level of quality is important, rather than be driven by company stakeholders.</p>
<p>What is the cost of an FTE in managing translation vendor projects?</p>
<p>Smart managers are using long-term contractors instead of FTEs.</p>
<p>&#8220;Cost per word&#8221; vs. impact of project. Product documentation is fairly easy to justify, but marketing programs need to be evaluated per product per market.</p>
<p>Instead of metrics on words, languages, projects do cost of content, brochure, etc. Cost to produce, manage, maintain each piece of content including overhead and external costs.</p>
<p>How does finance and accounting categorize and count things? How does that affect how and what you measure?</p>
<p>&#8220;measure&#8221; or &#8220;maysure&#8221;?</p>
<p>Thanks to Adobe for hosting the meeting tonite.</p>

			<content:encoded><![CDATA[<p><a href="www.spirit.com/">Spirit Airlines</a> is an ultra-low-cost USA air carrier that has a fleet of Airbus A320 planes, with similar aspirations to Ryanair in Europe.</p>
<p>Spirit is the most profitable US airline per airplane, and typically has 85-90% seat occupancy.</p>
<p>Ryanair and Spirit provide a glimpse into the future, which is very different than the glamorous portrayals of airline travel that Boeing and Airbus illustrate for new airplane models.</p>

			<content:encoded><![CDATA[<p>I just heard about the unfortunate crash of a Russian Sukhoi Superjet SSJ-100-95 into Mount Salak (Java) with about 44 people on board for a demonstration flight.</p>
<p>Having flown several times in that exact area, I can say that VFR flight there is very demanding:</p>
<ul>
<li>the weather was typical: partly cloudy at that time, likely broken to overcast at 2000&#8242; and 1 mile visibility (Marginal VFR conditions down to IMC, with clouds to the ground in the hills.) With 70% humidity and a small temperature/dewpoint (DP) spread, it&#8217;s cloudy 95% of the year over Jakarta. Residents also burn their trash, causing continuous smoke haze.
<li>Indonesia is a chain of volcanoes, which means &#8220;stratogranite&#8221; to pilots. There&#8217;s several mountains to the south of Jakarta, including Mount Salak. Outclimbing a mountain with 1 mile warning may not be possible and can result in an aerodynamic stall, which some witnesses reported (&#8220;the airplane flew over my house and fell out of the sky to one side.&#8221;)
<li>there are some restricted areas near Jakarta, including the <a href="http://en.wikipedia.org/wiki/Monas">National Monument (Monas)</a> and their version of the Pentagon, which can distract pilots momentarily &#8211; &#8220;We&#8217;re not over the Pentagon, are we?&#8221; <img src='http://www.jebriggs.com/blog/wp-includes/images/smilies/icon_neutral.gif' alt=':|' class='wp-smiley' />
</ul>
<p><center><br />
<img src="http://jebriggs.com/php/mt_salak.jpg" alt="Mt. Salak" title="Mt. Salak" border="0" /><br />
<br />
Mt. Salak on a rare clear day.<br />
</center></p>
<p>Recommendation: a local instructor pilot should be in the airplane cockpit for all demo flights. While local pilots can successfully do contact MVFR flying, visiting pilots can get into trouble.</p>
<p>Scheduled airline routes are quite safe to and from Jakarta, but I doubt if these passengers had any idea of the risk they were assuming in a demo flight.</p>
<p>Congrats to the Indonesian government for organizing at least 3 search parties and quickly finding the crash site.</p>
<p>Indonesia&#8217;s Sky Aviation lost many employees, so we&#8217;ll see how that affects their company. Sukhoi also lost several employees.</p>

<p>I hope Bruce Dickinson has more luck than that &#8230;</p>
<p>&#8220;Iron Maiden&#8217;s Bruce Dickinson – also a commercial airline pilot and entrepreneur – has set up Cardiff Aviation Limited, which will provide specialist services to the airline industry.</p>
<p>He hopes it will create around 1,000 jobs. The business will be based at St Athan Enterprise Zone in the Vale of Glamorgan, where it has taken 132,000 square feet of hangar space. The first clients will be announced next month.&#8221;</p>

			<content:encoded><![CDATA[<p><a href="http://techfieldday.com/2012/ssss12/">Solid State Storage Symposium 2012, San Jose</a> was held at the Doubletree Airport today and live streamed.</p>
<p>There were about 40 live attendees and 40-48 viewers online. I watched some of the events online.</p>
<p>The moderator kept the focus on technology instead of products, a challenge with the number of product vendors. Vendors can get so catty. <img src='http://www.jebriggs.com/blog/wp-includes/images/smilies/icon_smile.gif' alt=':)' class='wp-smiley' /> </p>
<p><strong>13:30 – Panel 1: Tier vs. Cache</strong></p>
<p>Solid State – Simply a big cache or a real storage tier?</p>
<p>&#8220;Solid state disks blur the boundary between cache and storage, with a foot in both camps. Can solid state drives really be treated as a new tier of storage or simply as a way to add more performance enhancing cache to existing arrays? This panel will discuss whether data should permanently reside on solid state media or whether the optimum and most cost effective solution is to simply use SSD to hold the working set of data in the array.&#8221;<br />

<strong>14:15 – Panel 2: Array Architecture</strong></p>
<p>What’s the best solid-state storage array architecture?</p>
<p>&#8220;The 20+ year old array architectures that are served up, day-in day-out, by the traditional vendors are struggling to cope with todays I/O demands. How they will cope with tomorrow’s is anyone’s guess. Looking to plug the hole and steal their business is an increasing crop of solid-state array vendors. Yet they’re all going about it entirely differently. This panel will get to the bottom of how to design great SSD arrays and why they’re architected like that.&#8221;<br />

<strong>15:00 – Panel 3: Future Architecture</strong></p>
<p>The Future of Solid State Storage</p>
<p>&#8220;Today we use flash and SSDs everywhere from notebooks to PCIe cards in servers and enterprise arrays. In this session our panel will consider the future of solid state storage systems and answer some interesting questions. Will SSDs kill spinning disk? Do 2.5” SAS or SATA disks have a place in the data center of the future? What does the next generation of flash bring to the market? What about PCM, Memristors and other new SSD technologies?&#8221;</p>
<p>Regarding APIs, the issue of lack of a standard came up. Everybody supports a linux block driver interface, but there is no agreement on APIs, similar to the GPU scientific computing market. Maybe see what the Open Source community comes up with, for example the MySQL community and its custom storage engines.</p>
<p>Other comments and notes:</p>
<ul>
<li><a href="http://www.vmware.com/products/drs/overview.html">VMware DRS</a> tiers storage devices, maybe you can manage SSD that way
<li>caching affects latency
<li>people want predictable, low latency
<li>although SAN increases latency, SAN users have decided that manageability is more important than latency
</ul>

<p>&#8220;<a href="http://storagemojo.com/">Robin [Harris]</a> has said that is the most exciting decade in storage. That means a lot coming from somebody as old as Robin.&#8221; <img src='http://www.jebriggs.com/blog/wp-includes/images/smilies/icon_smile.gif' alt=':)' class='wp-smiley' /> </p>
<p>The live streaming went well, with excellent video and clear audio.</p>
