Welcome back

Sorry about the outage but the VPS just became so unstable that it was unusable, and Steve was spending too much time fretting over the server rather than doing his analysis of climate science.

There are various things in the background which need to be setup, but hopefully all commenters can carry on commenting.

By the way, since this is the same server that runs auditblogs.com then some of you will be pleased to know that LaTeX is back:

\nabla \times E = \biggl ( \frac{\partial E_z}{\partial y} - \frac{\partial E_y} {\partial z} \biggr ) \vec x + \biggl ( \frac{\partial E_x}{\partial z} - \frac{\partial E_z}{\partial x} \biggr ) \vec y + \biggl ( \frac{\partial E_y}{\partial x} - \frac{\partial E_x}{\partial y} \biggr ) \vec z

Let me know if anything else is amiss.

    That’s funny. My message doesn’t show up in the recent messages though it’s here. It also doesn’t show in the # of Comments on this page. Looks like you have a bit more work to do to get things back to normal.

    Dave, John B – my guess is that John A has installed this WPCache module and it’s caching some portions of the page, to avoid having to recalculate them each time it’s loaded. That means some data (e.g. recent comments) may be lagged WRT the live data. It’s the price you pay for increasing the load-handling capabilities of the site. He may be able to dial back the amount of time it’s cached (to say 1 minute) to minimise what you’re noticing.

    Thanks for all of your work bringing up the new server!!!!!

    I have upgraded WordPress to the latest version (2.1 codename ‘Ella’ after Ella Fitzgerald)

    Amongst the highlights are:

    # Autosave makes sure you never lose a post again.

    # Our new tabbed editor allows you to switch between WYSIWYG and code editing instantly while writing a post.

    # The lossless XML import and export makes it easy for you to move your content between WordPress blogs.

    # Our completely redone visual editor also now includes spell checking.

    # New search engine privacy option allows you take you to indicate your blog shouldnt ping or be indexed by search engines like Google.

    # You can set any page to be the front page of your site, and put the latest posts somewhere else, making it much easier to use WordPress as a content management system.

    # Much more efficient database code, faster than previous versions. Domas Mituzas from MySQL went over all our queries with a fine-toothed comb.

    # Links in your blogroll now support sub-categories and you can add categories on the fly.

    # Redesigned login screen from the Shuttle project.

    # More AJAX to make custom fields, moderation, deletions, and more all faster. My favorite is the comments page, which new lets you approve or unapprove things instantly.

    # Pages can now be drafts, or private.

    # Our admin has been refreshed to load faster and be more visually consistent.

    # The dashboard now loads instantly and brings RSS feeds asynchronously in the background.

    # Comment feeds now include all the comments, not just the last 10.

    # Better internationalization and support for right-to-left languages.

    # The upload manager lets you easily manage all your uploads pictures, video, and audio.

    You can see where my biases are.

    john a…

    we still have “categories”, and “pages”…but we seem to have lost “links”, to RC, lubos, “truth or truthiness”, pielke, etc.

    i think the links section was here yesterday.

  18. Posted Feb 8, 2007 at 3:54 PM | Permalink

    fFredL Jeepers, I was trying to get Steve to be hip, cool and Web 2.0 by having Snap previews and then we get other old gits who don’t like it.

    Dave B: Yes I know about the links. It’s something that has broken and I need to fix it somehow.

    Everybody: To reduce the load on the MySQL database, I’ve enabled caching (set to 5 mins) so you won’t see your own comment updates for up to five mins. I’m sure you can manage 5 mins especially if you don’t like these new fangled gizmos they put on blogs these days – why do they have to change things that I was comfortable with?

    I hate Snap too. As Hans says, anyone who doesn’t like Snap you can disable it for all web sites next time a Snap pop-up appears by clicking on options. You can also disable Snap for all web site by going to this page


    and clicking on disable.

    This study has some really revealing model builders interviews . One modeler admits that all model builders cheat.

    Re 26 Russ:
    If that is the correct study, it was discussed in Truth Machines.

    To do a Google search on climateaudit, click on “advanced search” on the main Google Search page (which takes you here), select your search criteria and specify “climateaudit.org” in the Domain box. This works without adding any overhead to the blog. I understand that using the Google Search box on the site can slow things down quiet a bit.

    No, no revolutionary thoughts here 🙂 Just thinking aloud, if I understand Kerry Emanuel’s

    one cannot simulate the evolution of the climate over last 30 years without including in the simulations mankind’s influence on sulfate aerosols and greenhouse gases.

    correctly, it implies that evolution of the climate for the next 30 years can be predicted very accurately, if we knew volc, solar, etc for that period. Prediction error should be very uncorrelated (check Emanuel’s figure). So, they must have a predictive distribution,

    f_{(T \mid CO2, Solar, Volcanic, Aerosols)}

    which has lower variance than my famous ‘random walk temp’ climate distribution,

    f_{(T(k) \mid T(k-1))}=N(T(k-1),\sigma^2)

    where \sigma is approx. 0.15 K. Of course, my model is silly, but before I find the former distribution, I can’t tell you how silly it is. (And for testing, we need to spend some 30 years, but it is not important now..)

    Apologies for the outage. We had two crashes yesterday. The memory of the server was doubled to avoid this and unfortunately it took a day.

    Posted Feb 13, 2007 at 12:05 PM | Permalink

    Yeah. Tried 5-6 times over the past day and couldn’t get through.

    My memory might be failing me, but didn’t these problems start around the time the new site layout was instituted? Or maybe that was the reason for the change.

  47. Posted Feb 13, 2007 at 12:11 PM | Permalink

    No the problem is that the amount of memory on the server was not sufficient to cope with the load, and the pagefile filled up, and then it toppled over.

    I blame global warming.

    John, has the load increased significantly in the last couple of months ?

  50. Posted Feb 13, 2007 at 12:42 PM | Permalink

    The improved performance is because its a dedicated server rather than a VPS, which I regard as rather hit-and-miss in terms of performance depending on whom you’re sharing CPU and memory resources with.

    fFred: I don’t have statistics for the past couple of months (its one of the things we turned off because of our server problems) but impressionistically, the load on the server has continued to rise.
