Blogs Publishing Large NewsFeeds Can Cause Problems

We're seeing a few reports, which involve blogs with published newsfeeds with large volume, producing intriguing varieties of symptoms, in Blogger Help Forum: Something Is Broken.

My Followers are not getting email updates!

and

My blog does not update, on my Followers blogs!

and

My blog can't be viewed! All that I see is the gears turning!!!

All of these blog owners are publishing blogs which produce feeds, which are too large.

In general, a newsfeed can be any size necessary. There are two secondary details, however, which can make a Blogger blog, publishing a large newsfeed, problematic.

There is nothing basically wrong with large newsfeeds - but blogs which use dynamic templates, and blogs which produce feeds redirected through FeedBurner, can have problems when publishing large feeds.

We're currently seeing blogs with large feeds causing problems with dynamic templates. This produces one more case where we end up prescribing a non zero Timeout setting, for dynamic views.

Besides dynamic template display problems, blogs with large newsfeeds can produce problems, when redirected through FeedBurner. There are two approaches to making a feed smaller - use less posts - and alternately (when possible) format posts using Blogger post editor, instead of using Microsoft Office.

To diagnose a large feed problem, one can use any text browser, such as Rex Swain's HTTP Viewer, or maybe Web-Sniffer View HTTP Request and Response Header. Either product will provide a size display.

Feeds over 512K in size will be problematic, with either dynamic view, or FeedBurner redirection.

Dynamic Template Instabilities Have Multiple Causes

For some time, we've been seeing reports, in Blogger Help Forum: Something Is Broken, about blogs using blogs using dynamic views, which display incompletely, and lack specific features.

Various blog owners have developed, and reported, a workaround to the problem, which involves using an unpublicised Blogger setting found in the template HTML code. This workaround sets a loading delay, known as Timeout.

There are several different causes of the dynamic view problem - some varying by the different blogs, others varying by the blog viewers - and some, varying by the Blogger / Google infrastructure. None of the causes will be universal in effect. This will result in varying success, when using a static Timeout setting as a workaround for the problems.

The current workaround for the problem - changing the Timeout setting - will have immediate success with some blog owners, partial or temporary solution with many, and no solution with others.

The inconsistency will come from the various causes of the latency - and from the variety of symptoms being reported. The latency is the cause for development of the Timeout tweak.


There are three details which cause latency, and which result in missing dynamic view content, of varying effect.

• Complexity of blog content - unique to each blog.
• Computer and network issues - unique to each different client computer.
• Server and network issues - unique to the Blogger / Google networks and servers which support dynamic templates.

Complexity of blog content is the only detail which can be consistently resolved, by a change in the Timeout. As any dynamic template blog becomes more complex, increasing Timeout improves the chance that all blog content - including gadgets and template customisations - will be packaged before the blog is viewed. Each blog owner will be responsible for evaluating the need for this workaround, on an ongoing basis - based on current blog complexity.

Computer and network issues causes problems, that may be partially resolved, by the blog owners. Each blog owner can make the Timeout relevant to the known audience. Any blog, with an audience known to have problems, can be tuned by the blog owner, as necessary. Each blog owner will be responsible for evaluating the need for this workaround, on an ongoing basis - based on the needs of the majority of the known blog viewer audience.

Overall load on the Blogger / Google networks and servers causes problems that cannot be consistently resolved, by the blog owners. It's possible that some portion of the latency problem is regional in nature - in that Blogger / Google resources may not be evenly allocated, world wide, to support dynamic template use. Blogger / Google will be responsible for evaluating the need for this solution - based on current complaint level and load on network resources.

Any action taken by Blogger / Google will present a challenge, for several reasons. Note the problems discussed here are unique to dynamic views - because of the unique design of the dynamic templates.

• The Timeout setting will have a global effect, for each blog with a problem - even though the problem may not be global.
• As more blog owners resolve their immediate problems, by increasing the Timeout, this will put more load on Blogger / Google resources.
• As more blog owners report their immediate problems solved, this will encourage still more blog owners to use dynamic templates, and to try increasing the Timeout on their blogs.
• More blogs using dynamic templates will put still more load on Blogger / Google resources - and this will necessitate still more Timeout increases.
• Some blog owners, using computers or Internet service particularly susceptible to causing the symptoms, may try the basic workaround ("500"), which may not produce results - and may falsely conclude that their symptoms are not caused by the problem. A few owners may persistently try "1000", or "2000" or higher - and may eventually observe an improvement - while other owners may not.

The only long term solutions to this problem lies with Blogger / Google. Blogger / Google has two options.

• Halt or restrict customisations of dynamic templates.
• Tune their network resources better, to make latency less of an issue.

The latter option will require supporting action, by blog owners and readers.

• People who view blogs using dynamic templates have to tune their own computers and networks, so they do not contribute to the problem.
• Some blog owners may have to accept reality - that their reader audience simply can't be properly served, given the level of customisation required by their blog design.

The bottom line is that some blogs will never be properly served, if the owners insist on using dynamic templates, and customising uncontrollably. Blogger / Google cannot provide the universal solution.

Dynamic Template Instabilities Have Multiple Symptoms

Recently, we've been seeing a few reports, in Blogger Help Forum: Something Is Broken, about blogs using dynamic templates, which display incompletely, and lack specific features.

Various blog owners have developed, and reported, a workaround to the problem, which involves using an unpublicised Blogger setting found in the template HTML code. This workaround sets a loading delay, known as Timeout.

The currently recommended Timeout setting will force a fixed delay on blogs using the workaround, which may not be 100% effective in all cases. The effectiveness may vary, according to the specific problems reported by the various blog owners.

Problems reported by blog owners, which involve dynamic templates, center around several distinct areas.

• Absence of comments, displayed after the posts.
• Absence of multiple gadgets, in the popout sidebar.
• Absence of Pages entries in the display header bar.
• Absence of Posts ("No Posts Found"), with blogs heavy on photos.
• Absence of template tweaks, applied using "Add CSS".
• Absence of template tweaks, applied using "Edit HTML".

Each of these different symptoms will be caused by different needs, in publishing a blog - and the different symptoms will be observed by owners with different technical skill level.

Absence of multiple gadgets, in the popout sidebar is probably common to most blogs, as most blogs have more than one accessory gadget. Blog owners reporting this problem may be of very low technical skill level - and will likely have problems applying the workaround.

This problem may be more common than problem reports would imply - as not everybody with a blog, with this problem, will observe the unusually short accessory tab when the accessory bar is docked.

Absence of comments, displayed after the posts will be observed by blog owners who focus on comments, as part of their networking strategy. This will generally involve the more popular blogs (with lots of comments, making their absence more noticeable). Blog owners reporting this problem may be of low technical skill level - and may have problems applying the workaround.

This problem may be more common than problem reports would imply - as not everybody with a blog, with this problem, will observe the absence of comments, displayed after the posts. Some owners, with blogs which receive less comments than others, may not even care.

Absence of Pages entries in the display header bar will be reported by blog owners who have setup a complex structure of dynamic and static pages, and a Pages index to index the pages. The blog owners reporting this will have medium skill level, with the ability to use the Pages wizard. These owners may not necessarily have the ability - or desire - to use the Template Editor effectively. Some of these owners may have problems applying the workaround.

Absence of Posts ("No Posts Found"), with blogs heavy on photos, will be visible in blogs using "Flipcard", "Snapshot", and similar views. Blog owners reporting this problem may be publishing photoblogs. These blog owners will be those who spend a lot of time providing photos - and who may not notice other symptoms, like missing header or sidebar features. These blog owners may be of low technical skill level - and may have problems applying the workaround.

Absence of template tweaks, applied using "Add CSS" will be reported by blog owners who carefully applied appearance and style tweaks, using the Template Designer. The blog owners who apply these tweaks will have medium technical skill level, and the ability to use the "Add CSS" feature in the Template Designer. Some of these owners may have problems applying the workaround.

Absence of template tweaks, applied using "Edit HTML" will be reported by blog owners who customised the blog appearance, using the Template Editor. These blog owners will be of the highest technical skill level. These owners should have no problem applying the workaround.

With the assortment of problems to be fixed by Blogger Engineering, we will likely see each problem worked on, separately. As each problem is solved, we'll likely see new problems become more visible - and existing problems become more urgent, in the eyes of the blog owners.

The number of different possible symptoms, in combination with the number of possible causes of the problems, will create an apparently infinite number of differing complaints - and inconsistent visibility of the problems. Blogger Engineering will be busy, for a while, resolving these problems.

Dynamic Templates, And Network Problems - #2

We're been getting problem reports in Blogger Help Forum: Something Is Broken, from various dissatisfied blog owners, who chose a dynamic template for their blog.

The problems reported involve various symptoms.

• Blogs displayed will lack various gadgets, in the slideout gadget bar.
• Some blogs, when customised, will display using default layout and template settings.
• Some customisations, applied recently, just won't show up.

Various blog owners have discovered a solution, based on code present in newer dynamic templates. This solution has been publicised, in forum discussions - and in various blogs and web sites.

<script language='javascript' type='text/javascript'>
      setTimeout(function() {
        blogger.ui().configure().view();
      }, 1000);
</script>

The solution, as proposed, involves a very simple change - but the change won't be immediately, or permanently, 100% effective.

The solution, being publicised by various blog owners and forum helpers, involves a very simple change, using the template editor.

Once you have a secured a back up of your blog template, click on Edit HTML and you will see the html editor come up. Scroll down to the bottom of your template to where you see code that looks like this.

<script language='javascript' type='text/javascript'>
      setTimeout(function() {
        blogger.ui().configure().view();
      }, 0);
</script>

Change the 0 to 1000 so it looks like this.

<script language='javascript' type='text/javascript'>
      setTimeout(function() {
        blogger.ui().configure().view();
      }, 1000);
</script>

Click on Save Template.

Here, as always, I will strongly recommend that you backup the template, twice - before, and after, you make this template change.

This solution - changing the Timeout setting - will have immediate success with some blog owners, partial or temporary solution with many, and no solution with others.

The number of possible causes of the problems, in combination with the variety of possible symptoms, will create a visibly infinite number of differing complaints - and some complaints will continue, even with the workaround applied. Blogger Engineering will be busy, for a while, resolving these problems.

Once again, I'll suggest that you consider the functional and historical reasons for existence of the dynamic templates. Consider exercising some restraint, when customising your blog. Be part of the solution.

All Template Changes Won't Always Be Visible, When The Blog Is Published

Not all blog owners appreciate the differences between using the various template wizards, and what they will actually see, once the blog is published.

The confusion about the various template wizards, and what is actually seen, expressed in Blogger Help Forum: Something Is Broken, is numerous.

Why aren't my changes to the template being saved?

This question is expressed in a number of ways - and has a number of causes.

There are a number of causes of template problems, in general.

• Some problem are caused by Blogger Engineering, as they manage the Blogger application.
• Some problems are caused by the blog owners, as they use (and yes, misuse) the Blogger application.
• Some problems are simply caused by the perception of the blog owners, and will never be resolved, to everybody's expectations.

If you're viewing this blog using a desktop / laptop computer, with a "normal" browser, and you can find the "View Source" control, take a look at the source for this page. Compare what you see there with the display in the Template "Edit HTML" wizard (and allow for some confusion, when using "Edit HTML").

• If you have a "normal" browser, and are viewing this blog in a "Designer" / "Layout" template, you'll see a lot of the same code, in both "Edit HTML" and "View Source".
• If you have a "normal" browser, and are viewing this blog in a "Dynamic" template, you'll see very little of the same code, in both "Edit HTML" and "View Source".
• If you have a "normal" browser, and are viewing this blog using a redirected "mobile" browser view, you'll see very little of the same code, in both "Edit HTML" and "View Source".
• If you're using a "mobile" computer, you probably won't even have an option to "View Source".

The bulk of the options in the Template "Edit HTML" wizard, in the "Layout" wizard, and in the Template Designer, are intended to change the "Designer" / "Layout" template views. The three wizards have much less effect, against the "Dynamic" / "Mobile" template views.

If you tweak the CSS settings in "Edit HTML" or the Template Designer - or if you change the layout using "Layout" or the Template Designer - you may not see all of the changes reflected in either a Dynamic or Mobile view.

Sometimes, this is because you have already tweaked the template improperly, preventing the wizard from saving your latest changes. Other times, it may be simply because the Dynamic and Mobile templates are not designed to let you tweak the settings in question.

We've also seen vague suggestions that having the mobile template active can cause the Template Designer font and style selections to be non operational. Font settings, made using the Template Designer, won't be saved and won't appear in the blog, when published. Right now, we're unsure whether the Live Preview window updates reliably.

And recently, uncontrolled customisation of the blog accessory complement, and of the dynamic template code, have caused instability in network access, when viewing blogs using dynamic views.

What Are The Mysterious Turning Gears?

This is a question, occasionally seen in Blogger Help Forum: Something Is Broken.

I cannot view some blogs - all that I see are gears, turning endlessly. What is going on, here?

The gears are animation, displayed by Blogger, while a dynamic template and blog content loads on the computer being used. Generally, the gears will play for a few seconds, then the blog will be seen. For an example, check out my Musings blog.

Sometimes, all that you will see are the gears, endlessly turning - waiting for the templates and blog content to download.

The dynamic templates, used by some Blogger blogs, represent an innovative approach to providing web content.

Normal web content, provided in Blogger blogs which use Classic, Designer, and Layout class templates, consists of comments, gadgets, posts, and templates, arranged together in pages (dynamic and static).

Blogs which use Classic (HTML only) templates arranges everything when the blog is maintained. Blogs which use Designer / Layout templates (HTML / XML) arrange the content when the blog is maintained - then build the individual pages when the blog is read by each viewer, dynamically. For all 3 classes of templates, the content is served from Blogger / Google servers, in individual display pages.

The Dynamic class of Blogger templates take the concept of dynamic publishing to another level. Dynamic class templates load a significant amount of script code (the template) directly to each client computer. Instead of reading the pages of blog content from a Blogger / Google blog server, a dynamic template script, running on the client computer, reads the published blog feeds from a newsfeed server - then turns the feed content into a display.

A Dynamic template is a specialised Newsfeed Reader, similar to the dashboard Reading List, or to Google Reader.

By offloading a large amount of the publishing process to the client computer, and by using the blog comments and posts feeds, Blogger provides blogs which can be viewed in a number of different ways - selectable by each individual viewer, and at the convenience of the viewer. This selectability is not without cost, unfortunately.

• The templates require a significant amount of script code.
• The templates require the blog comments and posts newsfeeds.

For most blogs using a dynamic template, and being viewed on most computers, the "turning gears" icon plays briefly, while the template code, and the blog comments and posts newsfeeds, are downloaded. As soon as downloaded, the content is assembled into a display, and the viewer can view the blog. This does not happen, in all cases.

• Some client computers may filter the template code.
• Some client computers may not have a fast Internet connection.
• Some blogs may not publish a full newsfeed.

If the client computer has a slow Internet connection, the viewer may watch the turning gears for more than a few seconds. If the computer filters scripts aggressively, or if the blog does not publish a full newsfeed, the gears play, endlessly, while the computer waits for the scripts and newsfeeds to finish downloading. In the latter case, the viewer can only find another blog to view.

If you encounter one or two Blogger blogs playing the turning gears, endlessly, then you are experiencing the reality of dynamic templates - some blog owners do not realise that they have broken their blogs. If you encounter a large number of Blogger blogs doing this, then you might want to check the filters, on your computer - including, but not only, the browser cookie and script filters.

Some Blog Owners Reporting The Template Designer Changes Do Not Update On Their Blogs

For several weeks, we're been seeing various reports in Blogger Help Forum: Something Is Broken, mentioning problems with template updates, being made using the Template Designer wizard.

The reports are not so widespread to indicate a complete malfunction - but neither can we dismiss the problem, as being unique to one browser, one template type, or one particular update pattern.

It's likely that we are looking at a number of problems, aggregated and compounded, into one common symptom.

I cannot Save changes in Template Designer.

With a problem report like this, some examining of the details may be appropriate.

The Template Designer wizard, which is a component in the Blogger Dashboard, is a complex and sophisticated collection of menus and utilities, which runs on the blog owners computers.

Like most Blogger code, the Template Designer is subject to the effects of other programs, and various security settings - which may be installed or set on each individual computer, with or without the understanding of the blog owner and / or computer owner. In some cases, the blog owner and computer owner may be different people.

If you are seeing a problem with the Template Designer, when trying to update the layout on your blog, there are several tests which you can make, which may help to isolate the problem.

• Try making the same updates, using another computer.
• Try making the same updates, using another browser on your current computer.
• Try setting up a new blog, with the same template, and make the same updates to the new blog.

If you're able to make one or more of the above alternate updates, that will help to eliminate some, or many, alternate suspects, as the cause of your problem. If other people are reporting this problem, their results from the above tests may or may not correspond with yours - because their base problem may differ from yours.

Right now, we're seeing seven different causes of these problems.

1. Changes made by Blogger Engineering, to support new browser versions and browser updates, and to provide new template features.
2. Changes inherent in new browser versions, made by the browser vendors.
3. Third party browser add-ons, installed by the owners of the various computers.
4. Security settings, inherent in new browser versions and third party add-ons.
5. The cumulative effects of various template tweaks, both made using "Edit HTML" and the Template Designer itself.
6. Unrealistic expectations of blog owners, about effects of Template Designer settings, against all templates provided by Blogger.
7. Unrealistic expectations of blog owners, about effects of Template Designer settings, against templates not provided by Blogger.

Of these possible causes, only #1 (and possibly #2 and #6) are the sole responsibility of Blogger Engineering. The blog owners (and computer owners) must assume some partial responsibility for #2 - and sole responsibility for #3, #4, and #5. The blog owner, and the developer of any custom, third party template, must jointly assume responsibility for #7.

Recently, Blogger Support acknowledged the problem, in part.

Some users have reported that the Apply to Blog button in the Template Designer is non-functional for some Dynamic View templates.

We also have a Rollup Discussion, in Blogger Help Forum: Something Is Broken, where individual details are being provided by various blog owners.

Right now, we're starting to suspect that some "problems" are actually caused by the blog owners, who are simply not aware that not all changes made, using the Template Designer (or the Layout or Template "Edit HTML" wizards), are designed to update all templates used in viewing our blogs.
