			<content:encoded><![CDATA[<p>After <a href="http://www.linux.conf.au/">LCA [1]</a> there was a discussion about possible locations for future conferences, most of the messages in the discussion were jokes or suggestions that don&#8217;t seriously apply to LCA. So I&#8217;ll add my suggestion for conferences other than LCA.</p>
<p><a href="http://etbe.coker.com.au/2011/11/17/cruises/">I&#8217;ve previously written generally about the issue of conferences at sea [2]</a>. I don&#8217;t think that LCA would be suitable for running at sea because delegates have specific expectations for LCA which are quite different to what a cruise ship can offer, so I don&#8217;t think it makes sense to change LCA which is working well as it is. However there are lots of other possible computer conferences which could suite a cruise ship.</p>
<h3>Price</h3>
<p>Price is a major factor in running a conference, so obviously getting a cheap cruise price is very important. <a href="http://www.vacationstogo.com/ticker.cfm?r=15&#038;md=5&#038;mp=800">Here is a link for Vacations To Go which shows cruises from the Australia/NZ region which are of at least 5 nights and cost no more than $800 [3]</a>. The cheapest entry at this moment is $609 for 5 nights and the cheapest on a per-night basis is an 8 night cruise for $779. The cheapest cruise currently on offer which allows a conference similar to LCA is 7 nights for $699. The prices should be regarded as rough approximations as some cruises have some mandatory extra fees and the prices are quoted in US dollars and subject to currency fluctuations. Note that those prices are for dual-occupancy cabins, this can be a &#8220;double&#8221; or a &#8220;twin&#8221; configuration. Some cruise ships have cabins for 3 or 4 people that are cheaper, but if you have a cabin for a single person then the rate is almost the same as for having two people.</p>
<p>The price for LCA accommodation including breakfast was $78 per night for a single room or $92 for a double room. Then lunch cost a minimum of $10 and for dinner there was $80 for the penguin dinner and probably about $20 for dinner every other night. That gave an overall cost for a 6 night stay (which is probably the minimum for someone who lives further away than Melbourne) in Ballarat of 6*78+6*10+5*20+80==$708. For a double room that would be 6*92+6*10+5*20+2*80==$872.</p>
<p>Even if we don&#8217;t count the fact that the Australian dollar is worth more than the US dollar it is obvious that on the basis of accommodation and food two people sharing a twin cabin on a cruise ship could pay LESS than two people in single rooms at the Ballarat University dorms! Now sharing a cabin isn&#8217;t so great, but the upside is that cruise ships have excellent food and lots of other entertainment options. <a href="http://etbe.coker.com.au/2012/01/08/my-first-cruise/">I previously reviewed the food on the Dawn Princess and determined that it&#8217;s better than the food I would expect to get if I spent the cost of the cruise on dinner at land based restaurants [4]</a>.</p>
<p>I have been led to believe that the use of ship conference facilities is typically free for any organisation that books a sufficient number of cabins. So there&#8217;s no reason why the conference admission fees should be any greater than for a land based conference.</p>
<h3>Advantages</h3>
<p>A common problem with conferences is finding suitable dining options. Most people want to eat with other delegates but finding restaurants that have sufficient space and which are conveniently located is difficult at best and often impossible. On a cruise ship everything is within a short walk and the restaurants are big, usually be at least one restaurant will hold 500 people. The fact that you have to reserve times for the &#8220;Main Dining Room&#8221; makes it more difficult to miss one&#8217;s colleagues.</p>
<p>Everything on a cruise ship is luxurious.</p>
<p>There are lots of good locations for BoFs, pools, cafes, restaurants, and bars. Basically the ship is filled with comfortable places for groups of people to sit down.</p>
<p>A cruise ship typically has a main theater with more than 700 seats &#8211; more than large enough for most conferences I&#8217;ve attended. It&#8217;s common for the size of a conference to be limited to the size of the main theater that is used, for a cruise ship this will probably be less of a problem than for most other conference venues.</p>
<h3>Disadvantages</h3>
<p>The first disadvantage of running a computer conference on a cruise ship is the almost total lack of net access. The costs for net access are more expensive than most delegates will pay. Probably many delegates would check their email but it wouldn&#8217;t be practical for people to download source code, browse Wikipedia, and use the Internet in other ways related to the conference. It would be practical to have mirrors of Wikipedia, the source of several distributions of Linux, and other big things of common interest.</p>
<p>Another possible problem is the fact that you need to book it well in advance to avoid the risk of selling out (there is no option to stay at a different hotel). An established conference with financial backing could just pay to reserve the cabins. But when starting a new conference this could be a problem.</p>
<p>Alcohol is rather expensive on cruise ships. But getting really drunk isn&#8217;t compatible with learning about computer science anyway.</p>
<p>Finally the requirement to have at least two people in a cabin for good rates is a serious issue. The upside of this is that people travelling with their SO would find that it works really well (regardless of whether the SO is a delegate or not). But anyone who&#8217;s not travelling with their SO and doesn&#8217;t want to share with a friend will have to either pay a lot more or skip the conference.</p>
<h3>Conclusion</h3>
<p>I think that there is a good potential for running a computer conference around the Australia/NZ region on a cruise ship. It won&#8217;t be overly expensive for delegates and the facilities that are provided are good. The trade-off for solitary travelers of having to share a cabin (or pay more) for getting much better food and leisure facilities will be appreciated by many people (and admittedly hated by some).</p>
<p>Some people won&#8217;t appreciate the option of swimming, but even if you consider the cruise ship to be just a floating collection of restaurants and cabins it&#8217;s still fairly luxurious and beats the heck out of most conferences I&#8217;ve attended.</p>
<p>If you are considering the possibility of running a conference then I think that a cruise ship should be considered. <a href="http://www.vacationstogo.com">VacationsToGo.com is the best site I&#8217;ve found for cheap cruise prices</a>, their large group department has experience handling groups of more than 500 people so I think that anyone who wants to run a new conference in/around Australia should give them a call.</p>
<p>Also cruise ships travel around the world, so the same thing can be done in other countries but at a different time of year. The economic factors will differ by country though. Cruise ships probably aren&#8217;t a cheap option for a conference in some other countries.</p>

<p><a href="http://danwalsh.livejournal.com/48571.html">Dan Walsh describes how to get the RSA SecureID PAM module working on a SE Linux system [4]</a>. It&#8217;s interesting that RSA was telling everyone to turn off SE Linux and shipping a program that was falsely marked as needing an executable stack and which uses netstat instead of /dev/urandom for entropy. Really the only way RSA could do worse could be to fall victim to an Advanced Persistent Attack&#8230;  :-#</p>
<p><a href="http://longnow.org/seminars/02011/nov/30/universal-access-all-knowledge/">The Long Now has an interesting summary of a presentation about archive.org [5]</a>. I never realised the range of things that archive.org stores, I will have to explore that if I find some spare time!</p>

<p><a href="http://feeding.cloud.geek.nz/2011/12/optimising-png-files.html">François Marier wrote an informative article about optimising PNG files [7]</a>, optipng is apparently the best option at the moment but it doesn&#8217;t do everything you might want.</p>
<p><a href="http://www.helenkeeble.com/2011/08/08/repost-what-i-thought-about-twilight">Helen Keeble wrote an interesting review of Twilight [8]</a>. The most noteworthy thing about it IMHO is that she tries to understand teenage girls who like the books and movies. Trying to understand young people is quite rare.</p>
<p><a href="http://www.jonmasters.org/blog/2011/11/30/on-citizen-journalism/">Jon Masters wrote a critique of the concept of citizen journalism and described how he has two subscriptions to the NYT as a way of donating to support quality journalism [9]</a>. The only comment on his post indicates a desire for biased news (such as Fox) which shows the reason why most US media is failing at journalism.</p>
<p><a href="http://www.ted.com/talks/luis_von_ahn_massive_scale_online_collaboration.html">Luis von Ahn gave an interesting TED talk about crowd-sourced translation [10]</a>. He starts by describing CAPTCHAs and the way that his company ReCAPTCHA provides the CAPTCHA service while also using people&#8217;s time to digitise books. Then he describes his online translation service and language education system <a href="http://duolingo.com/">DuoLingo which allows people to learn a second language for free while translating text between languages [11]</a>. One of the benefits of this is that people don&#8217;t have to pay to learn a new language and thus poor people can learn other languages &#8211; great for people in developing countries that want to learn first-world languages! DuoLingo is in a beta phase at the moment but they are taking some volunteers.</p>

			<content:encoded><![CDATA[<p>Since <a href="http://etbe.coker.com.au/2011/10/31/selinux-status-2011-10/">my last SE Linux in Debian status report [1]</a> there have been some significant changes.</p>
<h3>Policy</h3>
<p>Last year I reported that the policy wasn&#8217;t very usable, on the 18th of January I uploaded version 2:2.20110726-2 of the policy packages that fixes many bugs. The policy should now be usable by most people for desktop operations and as a server. Part of the delay was that I wanted to include support for systemd, but as my work on systemd proceeded slowly and others didn&#8217;t contribute policy I could use I gave up and just released it. Systemd is still a priority for me and I plan to use it on all my systems when Wheezy is released.</p>
<h3>Kernel</h3>
<p>Some time between Debian kernel 3.0.0-2 and 3.1.0-1 support for an upstream change to the security module configuration was incorporated. Instead of using <b>selinux=1</b> on the kernel command line to enable SE Linux support the kernel option is <b>security=selinux</b>. This change allows people to boot with <b>security=tomoyo</b> or <b>security=apparmor</b> if they wish. No support for Smack though.</p>
<p>As the kernel silently ignores command line parameters that it doesn&#8217;t understand so there is no harm in having both <b>selinux=1</b> and <b>security=selinux</b> on both older and newer kernels. So version <b>0.5.0</b> of <b>selinux-basics</b> now adds both kernel command-line options to GRUB configuration when <b>selinux-activate</b> is run. Also when the package is upgraded it will search for <b>selinux=1</b> in the GRUB configuration and if it&#8217;s there it will add <b>security=selinux</b>. This will give users the functionality that they expect, systems which have SE Linux activated will keep running SE Linux after a kernel upgrade or downgrade! Prior to updating <b>selinux-basics</b> systems running Debian/Unstable won&#8217;t work with SE Linux.</p>
<p>As an aside the postinst file for <b>selinux-basics</b> was last changed in 2006 (thanks Erich Schubert). This package is part of the new design of SE Linux in Debian and some bits of it haven&#8217;t needed to be changed for 6 years! SE Linux isn&#8217;t a new thing, it&#8217;s been in production for a long time.</p>
<h3>Audit</h3>
<p>While the audit daemon isn&#8217;t strictly a part of SE Linux (each can be used without the other) it seems that most of the time they are used together (in Debian at least). I have prepared a NMU of the new upstream version of audit and uploaded it to delayed/7. I want to get everything related to SE Linux up to date or at least with comparable versions to Fedora. Also I sent some of the Debian patches for the auditd upstream which should reduce the maintenance effort in future.</p>
<h3>Libraries</h3>
<p>There have been some NMUs of libraries that are part of SE Linux. Due to a combination of having confidence in the people doing the NMUs and not having much spare time I have let them go through without review. I&#8217;m sure that I will notice soon enough if they don&#8217;t work, my test systems exercise enough SE Linux functionality that it would be difficult to break things without me noticing.</p>
<h3>Play Machine</h3>
<p>I am now preparing a new SE Linux &#8220;Play Machine&#8221; running Debian/Unstable. I wore my Play Machine shirt at LCA so I&#8217;ve got to get one going again soon. This is a good exercise of the strict features of SE Linux policy, I&#8217;ve found some bugs which need to be fixed. Running Play Machines really helps improve the overall quality of SE Linux.</p>

			<content:encoded><![CDATA[<p>A few weeks ago I went on my first cruise, from Sydney to Melbourne on the Dawn Princess. VacationsToGo.com (a discount cruise/resort web site) has <a href="http://www.vacationstogo.com/cruise_ship/Dawn_Princess.cfm">a review of the Dawn Princess [1]</a>, they give it 4 stars out of a possible 6. The 6 star ships seem to have discount rates in excess of $500 per day per person, much more than I would pay.</p>
<p>The per-person rate is based on two people sharing a cabin, it seems that most cabins can be configured as a double bed or twin singles. If there is only one person in a cabin then they pay almost double the normal rate. It seems that most cruise ships have some support for cabins with more than two people (at a discount rate), but the cabins which support that apparently sell out early and don&#8217;t seem to be available when booking a cheap last-minute deal over the Internet. So if you want a cheap cruise then you need to have an even number of people in your party.</p>
<p>The cruise I took was two nights and cost $238 per person, it was advertised at something like $220 but then there are extra fees when you book (which seems to be the standard practice).</p>
<h3>The Value of Cruises</h3>
<p>To book a hotel room that is reasonably comfortable (4 star) in Melbourne or Sydney you need to spend more than $100 per night for a two person room if using <a href="http://www.wotif.com/">Wotif.com</a>. The list price of a 4 star hotel room for two people in a central city area can be well over $300 per night. So the cost for a cruise is in the range of city hotel prices.</p>
<p>The Main Dining Room (MDR) has a quality of food and service that compares well with city restaurants. The food and service in the Dawn Princess MDR wasn&#8217;t quite as good as <a href="http://www.walterswinebar.com.au/">Walter&#8217;s Wine Bar</a> (one of my favorite restaurants). But Walter&#8217;s costs about $90 for a four course meal. The Dawn Princess MDR has a standard 5 course meal (with a small number of options for each course) and for no extra charge you can order extra serves. When you make it a 7 course meal the value increases. I really doubt that I could find any restaurant in Melbourne or Sydney that would serve a comparable meal for $119.</p>
<p>You could consider a cruise to be either paying for accommodation and getting everything else for free or to be paying for fine dining in the evening and getting everything else for free. Getting both for the price of one (along with entertainment etc) is a great deal!</p>
<p>I can recommend a cruise as a good holiday which is rather cheap if you do it right. That is if you want to spend lots of time swimming and eating quality food.</p>
<h3>How Cruise Companies Make Money</h3>
<p>There are economies of scale in running a restaurant, so having the MDR packed every night makes it a much more economic operation than a typical restaurant which has quiet nights. But the expenses in providing the services (which involves a crew that is usually almost half the number of passengers) are considerable. Paying $119 per night might cover half the wages of an average crew member but not much more.</p>
<p>The casino is one way that the cruise companies make money. I can understand that someone taking a luxury vacation might feel inclined to play blackjack or something else that seems sophisticated. But playing poker machines on a cruise ship is rather sad &#8211; not that I&#8217;m complaining, I&#8217;m happy for other people to subsidise my holidays!</p>
<p>Alcohol is rather expensive on board. Some cruise companies allow each passenger to take one bottle of wine and some passengers try to smuggle liquor on board. On the forums some passengers report that they budget to spend $1000 per week on alcohol! If I wanted a holiday that involved drinking that much I&#8217;d book a hotel at the beach, mix up a thermos full of a good cocktail in my hotel room, and then take my own deck-chair to the beach.</p>
<p>It seems that the cruise companies specialise in extracting extra money from passengers (I don&#8217;t think that my experience with the Dawn Princess is unusual in any way). Possibly the people who pay $1000 per night or more for a cruise don&#8217;t get the nickel-and-dime treatment, but for affordable cruises I think it&#8217;s standard. You have to be in the habit of asking the price whenever something is offered and be aware of social pressure to spend money.</p>
<p>When I boarded the Dawn Princess there was a queue, which I joined as everyone did. It turned out that the queue was to get a lanyard for holding the key-card (which opens the cabin door and is used for payment). After giving me the lanyard they then told me that it cost $7.95 &#8211; so I gave it back. Next time I&#8217;ll take a lanyard from some computer conference and use it to hold the key-card, it&#8217;s handy to have a lanyard but I don&#8217;t want to pay $7.95.</p>
<p>Finally some things are free at some times but not at others, fruit juice is free at the breakfast buffet but expensive at the lunch buffet. Coffee at the MDR is expensive but it was being served for free at a cafe on deck.</p>
<h3>How to have a Cheap Cruise</h3>
<p><a href="http://www.vacationstogo.com/">VacationsToGo.com is the best discount cruise site I&#8217;ve found so far [2]</a>. Unfortunately they don&#8217;t support searching on price, average daily price, or on a customised number of days (I can search for 7 days but not 7 or less). For one of the cheaper vessels it seems that anything less than $120 per night is a good deal and there are occasional deals as low as $70 per night.</p>
<p>Princess cruises allows each passenger to bring one bottle of wine on board. If you drink that in your cabin (to avoid corkage fees) then that can save some money on drinks. <a href="http://www.rumrunnerflasks.com/">RumRunnerFlasks.com sells plastic vessels for smuggling liquor on board cruise ships [3]</a>. I wouldn&#8217;t use one myself but many travelers recommend them highly.</p>
<p>Chocolate and other snack foods are quite expensive on board and there are no restrictions on bringing your own, so the cheap options are to bring your own snack food or to snack from the buffet (which is usually open 24*7). Non-alcoholic drinks can be expensive but you can bring your own and use the fridge in your cabin to store it, but you have to bring cans or pressurised bottles so it doesn&#8217;t look like you are smuggling liquor on board.</p>
<p>Generally try not to pay for anything on board, there&#8217;s enough free stuff if you make good choices.</p>
<p>Princess offers free on-board credit (money for buying various stuff on-board) for any cruise that you book while on a cruise. The OBC starts at $25 per person and goes as high as $150 per person depending on how expensive the cruise is. Generally booking cruises while on-board is a bad idea as you can&#8217;t do Internet searches. But as Princess apparently doesn&#8217;t allow people outside the US to book through a travel agent and as they only require a refundable deposit that is not specific to any particular cruise there seems no down-side. In retrospect I should have given them a $200 on the off chance that I&#8217;ll book another cruise with them some time in the next four years.</p>
<p>Princess provide a book of discount vouchers in every cabin, mostly this is a guide to what is most profitable for them &#8211; and thus what you should avoid if you want a cheap holiday. But there are some things that could be useful such as a free thermos cup with any cup of coffee &#8211; if you buy coffee then you might as well get the free cup. Also they have some free contests that might be worth entering.</p>
<h3>Entertainment</h3>
<p>It&#8217;s standard practice to have theatrical shows on board, some sort of musical is standard and common options include a magic show and comedy (it really depends on which cruise you take). On the Dawn Princess the second seating for dinner started at 8PM (the time apparently varies depending on the cruise schedule) which was the same time as the first show of the evening. I get the impression that this sort of schedule is common so if you want to see two shows in one night then you need to have the early seating for dinner. The cruise that I took lasted two nights and had two shows (a singing/dancing show and a magic show), so it was possible to have the late seating for dinner and still see all the main entertainment &#8211; unless you wanted to see one show twice.</p>
<p>From reading the <a href="http://boards.cruisecritic.com/">CruiseCritic.com forum [4]</a> I get the impression that the first seating for dinner is the most popular. On some cruises it&#8217;s easy to switch from first to second seating but not always possible to switch from second to first. Therefore the best strategy seems to be to book the first seating.</p>
<h3>Things to do Before Booking a Cruise</h3>
<p>Read the CruiseCritic.com forum for information about almost everything.</p>
<p>Compare prices for a wide variety of cruises to get a feel for what the best deals are. While $100 per night is a great deal for the type of cruise that interests me and is in my region it may not be a good match for the cruises that interest you.</p>
<p>Read overview summaries of cruise lines that operate in your area. Some cruise lines cater for particular age groups and interests and are thus unappealing to some people &#8211; EG anyone who doesn&#8217;t have children probably won&#8217;t be interested in Disney cruises.</p>
<p>Read reviews of the ships, there is usually a great variation between different ships run by one line. One factor is when the ships have been upgraded with recently developed luxury features.</p>
<p>Determine what things need to be booked in advance. Some entertainment options on board support a limited number of people and get booked out early. For example if you want to use the VR golf simulator on the Dawn Princess you should probably check in early and make a reservation as soon as you are on board. The forums are good for determining what needs to be booked early.</p>

			<content:encoded><![CDATA[<p>I&#8217;ve got some performance problems with a mail server that&#8217;s using DRBD so I&#8217;ve done some benchmark tests to try and improve things. I used <a href="http://doc.coker.com.au/projects/postal/">Postal for testing delivery to an LMTP server [1]</a>. The version of Postal I released a few days ago had a bug that made LMTP not work, I&#8217;ll release a new version to fix that next time I work on Postal &#8211; or when someone sends me a request for LMTP support (so far no-one has asked for LMTP support so I presume that most users don&#8217;t mind that it&#8217;s not yet working).</p>
<p>The local spool on my test server is managed by Dovecot, the Dovecot delivery agent stores the mail and the Dovecot POP and IMAP servers provide user access. For delivery I&#8217;m using the LMTP server I wrote which has been almost ready for GPL release for a couple of years. All I need to write is a command-line parser to support delivery options for different local delivery agents. Currently my LMTP server is hard-coded to run /usr/lib/dovecot/deliver and has it&#8217;s parameters hard-coded too. As an aside if someone would like to contribute some GPL C/C++ code to convert a string like &#8220;<b>/usr/lib/dovecot/deliver -e -f %from% -d %to% -n</b>&#8221; into something that will populate an argv array for execvp() then that would be really appreciated.</p>
<p>Authentication is to a MySQL server running on a fast P4 system. The MySQL server was never at any fraction of it&#8217;s CPU or disk IO capacity so using a different authentication system probably wouldn&#8217;t have given different results. I used MySQL because it&#8217;s what I&#8217;m using in production. Apart from my LMTP server and the new version of Postal all software involved in the testing is from Debian/Squeeze.</p>
<h3>The Tests</h3>
<p>All tests were done on a 20G IDE disk. I started testing with a Pentium-4 1.5GHz system with 768M of RAM but then moved to a Pentium-4 2.8GHz system with 1G of RAM when I found CPU time to be a bottleneck with barrier=0. All test results are for the average number of messages delivered per minute for a 19 minute test run where the first minute&#8217;s results are discarded. The delivery process used 12 threads to deliver mail.</p>

<tr>
<td>Ext4 on DRBD no secondary</td>
<td>1810</td>

</table>
<p>When doing the above tests the 1.5GHz system was using 100% CPU time when the filesystem was mounted with barrier=0, about half of that was for system (although I didn&#8217;t make notes at the time). So the testing on the 1.5GHz system showed that increasing the Ext4 max_batch_time number doesn&#8217;t give a benefit for a single disk, that mounting with barrier=0 gives a significant performance benefit, and that using DRBD in disconnected mode gives a good performance benefit through forcing barrier=0. As an aside I wonder why they didn&#8217;t support barriers on DRBD given all the other features that they have for preserving data integrity.</p>
<p>The tests with the 2.8GHz system demonstrate the performance benefits of having adequate CPU power, as an aside I hope that Ext4 is optimised for multi-core CPUs because if a 20G IDE disk needs a 2.8GHz P4 then modern RAID arrays probably require more CPU power than a single core can provide.</p>
<p>It&#8217;s also interesting to note that a degraded DRBD device (where the secondary has never been enabled) only gives 84% of the performance of /dev/sda4 when mounted with barrier=0.</p>

</tr>
</table>
<p>Of all the options for batch times that I tried it seemed that every change decreased the performance slightly but as the greatest decrease in performance was only slightly more than 2% it doesn&#8217;t matter much.</p>
<p>One thing that really surprised me was the test results from different replication protocols. The <a href="http://www.drbd.org/users-guide/s-replication-protocols.html">DRBD replication protocols are documented here [2]</a>. Protocol C is fully synchronous &#8211; a write request doesn&#8217;t complete until the remote node has it on disk. Protocol B is memory synchronous, the write is complete when it&#8217;s on a local disk and in RAM on the other node. Protocol A is fully asynchronous, a write is complete when it&#8217;s on a local disk. I had expected protocol A to give the best performance as it has lower latency for critical write operations and for protocol C to be the worst. My theory is that DRBD has a performance bug for the protocols that the developers don&#8217;t recommend.</p>
<p>One other thing I can&#8217;t explain is that according to iostat the data partition on the secondary DRBD node had almost 1% more sectors written than the primary and the number of writes was more than 1% greater on the secondary. I had hoped that with protocol A the writes would be combined on the secondary node to give a lower disk IO load.</p>
<p><a href="http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=654206">I filed Debian bug report #654206 about the kernel not exposing the correct value for max_batch_time</a>. The fact that no-one else has reported that bug (which is in kernels from at least 2.6.32 to 3.1.0) is an indication that not many people have found it useful.</p>
<h3>Conclusions</h3>
<p>When using DRBD use protocol C as it gives better integrity and better performance.</p>
<p>Significant CPU power is apparently required for modern filesystems. The fact that a <a href="http://support.dell.com/support/edocs/storage/7j376/specs.htm">Maxtor 20G 7200rpm IDE disk [3]</a> can&#8217;t be driven at full speed by a 1.5GHz P4 was a surprise to me.</p>
<p>DRBD significantly reduces performance when compared to a plain disk mounted with barrier=0 (for a fair comparison). The best that DRBD could do in my tests was 55% of native performance when connected and 84% of native performance when disconnected.</p>
<p>When comparing a cluster of cheap machines running DRBD on RAID-1 arrays to a single system running RAID-6 with redundant PSUs etc the performance loss from DRBD is a serious problem that can push the economic benefit back towards the single system.</p>
<p>Next I will benchmark DRBD on RAID-1 and test the performance hit of using bitmaps with Linux software RAID-1.</p>
<p>If anyone knows how to make a HTML table look good then please let me know. It seems that the new blog theme that I&#8217;m using prevents borders.</p>
<p><b>Update:</b></p>
<p>I mentioned my Debian bug report about the mount option and the fact that it&#8217;s all on Debian/Squeeze.</p>

			<content:encoded><![CDATA[<p><a href="http://www.news.com.au/entertainment/fashion/child-beauty-pageant-under-for-awarding-autistic-girl-tahnee-myles-best-personailty/story-e6frfn7i-1226106345484">Fenella Wagener wrote an article for the Herald Sun about an Autistic girl who won the &#8220;best personality&#8221; award from the controversial new Australian children&#8217;s beauty pageant [1]</a>. The girl&#8217;s mother is complaining that an Autistic girl shouldn&#8217;t win a prize for personality and is critizing the pageant organisers.</p>
<p>A beauty contest involves queuing, being quiet, appearing on stage, wearing cosmetics and unusual/uncomfortable clothes. It probably also involves having someone else assist with dressing and applying cosmetics (being touched by another person). These are all things which tend to be difficult or impossible for Autistic kids. So any girl who can get on stage wearing make-up can probably do whatever is required to avoid being obviously excluded from a personality prize. As any such prize has to be largely subjective I don&#8217;t think it would ever be possible to prove that someone was the correct choice for the winner, it would merely be possible to prove that some candidates excluded themselves.</p>
<p>But whether the girl deserved to win isn&#8217;t the real issue here. I think that beauty pageants should be restricted to adults, merely entering a child in such a contest is bad enough, but making nasty public statements about a child is horrible. If other children made a Facebook page claiming that the girl in question didn&#8217;t deserve to win a &#8220;best personality&#8221; prize it would probably be reported as cyber-bullying. I don&#8217;t think that publishing the name or photo of the girl in question is in the &#8220;public interest&#8221; either. Many news sites that have picked up the story have shown the same lack of journalistic ethics so now the girl has some high traffic sites with her name linked to this story, it seems unlikely that anything good she might do in the near future will get a higher ranking for her name in search engines. So any time she searches for her name on Google (which most people do regularly) she will be reminded that her mother thinks she has some sort of defective personality because she is Autistic.</p>
<p>High school is generally bad for almost everyone on the Autism Spectrum. Presumably any parent who would abuse their child by allowing such an article to be published would also send them to a regular school (as opposed to <a href="http://en.wikipedia.org/wiki/Home_school">Home Schooling</a> which is probably the only good option for Autistic kids in Australia). I&#8217;m sure that the standard practice at every high school nowadays is that the kids all use Google to discover things to tease each other about. So in a few years the Herald Sun article will probably be the basis of a high school bullying campaign.</p>
<p>The girl in question is only 9, so she&#8217;s got another 6 or 7 years before she can legally leave her mother. In Australia 16 is the minimum legal age to live without parents and the police won&#8217;t forcibly return &#8220;runaway&#8221; children who are almost 16.</p>
<h3>The Journalistic Code of Ethics</h3>
<p><a href="http://www.alliance.org.au/code-of-ethics.html">Here is a link to the Australian Media Alliance code of Journalistic Ethics [2]</a>. Section 8 includes &#8220;<b>Never exploit a person&#8217;s vulnerability or ignorance of media practice</b>&#8220;. I think that publishing the name and photograph of a 9yo girl in a way that is likely to lead to bullying in a few years is a clear example of exploiting a vulnerable person.</p>
<p>The code of ethics has a guidance clause which says &#8220;<b>Only substantial advancement of the public interest or risk of substantial harm to people allows any standard to be overridden</b>&#8220;. Even if it was a proven fact that a beauty pageant was issuing awards to unqualified children there would not be any substantial advancement of the public interest in publishing that.</p>
<h3>Beauty Contests are Evil</h3>
<p><a href="http://www.theaustralian.com.au/news/features/ugly-truth-about-beauty-pageants/story-e6frg6z6-1226106209926">The Australian has an article about the same beauty contest by Caroline Overington which quotes adolescent and child psychotherapist Collett Smart calling for government intervention [3]</a>.</p>
<p><a href="http://www.onlineopinion.com.au/view.asp?article=12506">Catherine Manning has written a good article explaining some of the reasons for opposing child beauty pageants [4]</a>.</p>
<p><a href="http://www.apa.org/pi/women/programs/girls/report.aspx">The American Psychological Association has published a report on the Sexualization of Girls [5]</a>, they have lots of references to psychological research which gives a variety of reasons for opposing child beauty contests. IMHO each of the reasons alone should be sufficient to convince people that child beauty pageants are bad.</p>
<p>Finally the pictures of contestants who are less than 10yo but made up to look like they are 20+ are rather disturbing.</p>
