Portals WikiProject update #014, 27 July 2018

Development of design continues, full speed ahead...

Excerpt slideshows are here!

Can you say "paradigm shift"?

Now, in addition to picture slideshows, we have slideshows that can display excerpts. Portals are not just for topic tasting anymore. Now they can be made useful for surveying Wikipedia's coverage of entire subjects. This gives a deeper meaning to their name. Hmmm. "Portals"... Doorways to knowledge.

Portal:Lithuania was redesigned using excerpt slideshows. Check it out.

For those of you who cannot wait to test out these new toys...

We have not one, but three excerpt slideshow components to pick from:

{{Transclude excerpts as random slideshow}}

For this one, you specify the page names where the excerpts are to be extracted from.

{{Transclude list item excerpts as random slideshow}}

This one accepts source pages from where the page names are gathered from list items. Then an excerpt from one of those pages is displayed. The selection of what is included in the slide show can be limited to a specific number from the collection (of the page names gathered), and that selection is renewed from scratch each time the page is purged.
For example, if you specify Template:World Heritage Sites in Spain as a source page, the slideshow will cycle through those sites. Now you don't have to type them in one-by-one. This greatly reduces portal creation time.

{{Transclude linked excerpts as random slideshow}}

Same as above, but gathers links instead of just linked list items.

Panoramic banners

{{Portal image banner}} displays a panoramic picture the width of the page, and adjusts its size, so it stays that way even if the user changes page view size. And it accepts multiple file names, so that the picture displayed randomizes between them each time the page is visited/purged.

Give resizing the page a try:

Vilnius, the capital of Lithuania.

You can now balance section boxes

  • Image 1 Various types of frog A frog is any member of a diverse and largely carnivorous group of short-bodied, tailless amphibians composing the order Anura (ἀνούρα, literally without tail in Ancient Greek). The oldest fossil "proto-frog" Triadobatrachus is known from the Early Triassic of Madagascar, but molecular clock dating suggests their split from other amphibians may extend further back to the Permian, 265 million years ago. Frogs are widely distributed, ranging from the tropics to subarctic regions, but the greatest concentration of species diversity is in tropical rainforest. Frogs account for around 88% of extant amphibian species. They are also one of the five most diverse vertebrate orders. Warty frog species tend to be called toads, but the distinction between frogs and toads is informal, not from taxonomy or evolutionary history. An adult frog has a stout body, protruding eyes, anteriorly-attached tongue, limbs folded underneath, and no tail (the tail of tailed frogs is an extension of the male cloaca). Frogs have glandular skin, with secretions ranging from distasteful to toxic. Their skin varies in colour from well-camouflaged dappled brown, grey and green to vivid patterns of bright red or yellow and black to show toxicity and ward off predators. Adult frogs live in fresh water and on dry land; some species are adapted for living underground or in trees. Frogs typically lay their eggs in water. The eggs hatch into aquatic larvae called tadpoles that have tails and internal gills. They have highly specialized rasping mouth parts suitable for herbivorous, omnivorous or planktivorous diets. The life cycle is completed when they metamorphose into adults. A few species deposit eggs on land or bypass the tadpole stage. Adult frogs generally have a carnivorous diet consisting of small invertebrates, but omnivorous species exist and a few feed on plant matter. Frog skin has a rich microbiome which is important to their health. Frogs are extremely efficient at converting what they eat into body mass. They are an important food source for predators and part of the food web dynamics of many of the world's ecosystems. The skin is semi-permeable, making them susceptible to dehydration, so they either live in moist places or have special adaptations to deal with dry habitats. Frogs produce a wide range of vocalizations, particularly in their breeding season, and exhibit many different kinds of complex behaviors to attract mates, to fend off predators and to generally survive.

  • Image 2 Oscaecilia ochrocephala (Caeciliidae) Caecilians (/sɪˈsɪliən/; New Latin for 'blind ones') are a group of limbless, vermiform (worm-shaped) or serpentine (snake-shaped) amphibians with small or sometimes nonexistent eyes. They mostly live hidden in soil or in streambeds, and this cryptic lifestyle renders caecilians among the least familiar amphibians. Modern caecilians live in the tropics of South and Central America, Africa, and southern Asia. Caecilians feed on small subterranean creatures such as earthworms. The body is cylindrical and often darkly coloured, and the skull is bullet-shaped and strongly built. Caecilian heads have several unique adaptations, including fused cranial and jaw bones, a two-part system of jaw muscles, and a chemosensory tentacle in front of the eye. The skin is slimy and bears ringlike markings or grooves and may contain scales. Modern caecilians are a clade, the order Gymnophiona /ˌdʒɪmnəˈfaɪənə/ (or Apoda /ˈæpədə/), one of the three living amphibian groups alongside Anura (frogs) and Urodela (salamanders). Gymnophiona is a crown group, encompassing all modern caecilians and all descendants of their last common ancestor. There are more than 220 living species of caecilian classified in 10 families. Gymnophionomorpha is a recently coined name for the corresponding total group which includes Gymnophiona as well as a few extinct stem-group caecilians (extinct amphibians whose closest living relatives are caecilians but are not descended from any caecilian). Some palaeontologists have used the name Gymnophiona for the total group and the old name Apoda for the crown group'. However, Apoda has other even older uses, including as the name of a genus of Butterfly making its use potentially confusing and best avoided. 'Gymnophiona' derives from the Greek words γυμνος / gymnos (Ancient Greek for 'naked') and οφις / ophis (Ancient Greek for 'snake'), as the caecilians were originally thought to be related to snakes and to lack scales. The study of caecilian evolution is complicated by their poor fossil record and specialized anatomy. Genetic evidence and some anatomical details (such as pedicellate teeth) support the idea that frogs, salamanders, and caecilians (collectively known as lissamphibians) are each others' closest relatives. Frogs and salamanders show many similarities to dissorophoids, a group of extinct amphibians in the order Temnospondyli. Caecilians are more controversial; many studies extend dissorophoid ancestry to caecilians. Some studies have instead argued that caecilians descend from extinct lepospondyl or stereospondyl amphibians, contradicting evidence for lissamphibian monophyly (common ancestry). Rare fossils of early gymnophionans such as Eocaecilia and Funcusvermis have helped to test the various conflicting hypotheses for the relationships between caecilians and other living and extinct amphibians.

  • Image 3 Spotted salamander, Ambystoma maculatum Salamanders are a group of amphibians typically characterized by their lizard-like appearance, with slender bodies, blunt snouts, short limbs projecting at right angles to the body, and the presence of a tail in both larvae and adults. All ten extant salamander families are grouped together under the order Urodela from the group Caudata. Salamander diversity is highest in eastern North America, especially in the Appalachian Mountains; most species are found in the Holarctic realm, with some species present in the Neotropical realm. Salamanders never have more than four toes on their front legs and five on their rear legs, but some species have fewer digits and others lack hind limbs. Their permeable skin usually makes them reliant on habitats in or near water or other cool, damp places. Some salamander species are fully aquatic throughout their lives, some take to the water intermittently, and others are entirely terrestrial as adults. This group of amphibians is capable of regenerating lost limbs as well as other damaged parts of their bodies. Researchers hope to reverse engineer the regenerative processes for potential human medical applications, such as brain and spinal cord injury treatment or preventing harmful scarring during heart surgery recovery. The remarkable ability of salamanders to regenerate is not just limited to limbs but extends to vital organs such as the heart, jaw, and parts of the spinal cord, showing their uniqueness compared to different types of vertebrates. ⁤⁤This ability is most remarkable for occurring without any type of scarring. ⁤⁤This has made salamanders an invaluable model organism in scientific research aimed at understanding and achieving regenerative processes for medical advancements in human and animal biology.

Please keep the file size down below 2 megabytes, and keep in mind that you may find quality banners at commons: at less than 200K (.2 megabytes). Good search terms to include with the place name are "banner", "cityscape", "skyline", "panorama", "landscape", etc.

Related task: There are also lots of geography portals that have panoramas used as gaudy banners (with print or icons splattered across them) or that display them in some random location on the page. In many cases, those pages would be improved by displaying the panorama as a clean picture at the top of the intro section, like on the examples above. This works best with banner-like panoramas. Please fix such pages when you come across them, if you believe it would improve the look of the page.

Taller images might be better suited displayed further down the page, or in the "Selected images" section.

Note that {{Portal image banner}} supports multiple images, and displays one at random upon the first visit, and each time the page is purged.

Fun activity #2: install "Selected images" sections

That is, image slideshows!

Over 200 have been installed so far. Just 1200 to go. (Be sure not to install them on portals with active maintainers, unless they want you to).

The title "Selected images" reflects the fact that not all images on Wikipedia are pictures, and encompasses maps, graphs, diagrams, sketches, paintings, pictures, and so on.

The toys we have to work with for this are:

{{Random slideshow}}

and

{{Transclude files as random slideshow}}

The task: Using one of the above templates directly on a portal's base page, replace static "Selected picture" sections, with a section like one of these:

Selected images
  • Image 1Salmon fry hatching (Salmo salar) - the larva has grown around the remains of the yolk - visible are the arteries spinning around the yolk and little oildrops, also the gut, the spine, the main caudal blood vessel, the bladder and the arcs of the gills.

  • Image 2Koi are ornamental domesticated varieties of the common carp Cyprinus carpio, originated from China and widely spread in Japan. They are very closely related to goldfish. The word "koi" comes from Japanese meaning "carp".

Selected images

The one on the left uses {{Random slideshow}} (which accepts file names), and the one on the right uses {{Transclude files as random slideshow}} (which accepts source pages from which the filenames are gathered).

The above section formatting is used on many of the pages you will come across, but not all. In those cases, use whatever section formatting matches the rest of the page.

Note that you may come across "Selected picture" sections done with {{Random portal component}} templates. That template call is the entire section. Replace it with a section that matches the other sections on the page, and put the new slideshow inside that.

For example, in Portal:California, this code:

{{Random portal component|max=21|seed=27|header=Selected picture|subpage=Selected picture}}

was replaced with this code: 

{{/box-header|Selected images|noedit=yes}}
{{Transclude files as random slideshow
| {{PAGENAME}}
| Culture of {{PAGENAME}}
}}
{{Box-footer}}

And the new section blended right in with the formatting of the rest of the page. Note the use of the {{PAGENAME}} magic word. Plain article titles also work. Don't feel limited to one or two page names. But be sure to test each slideshow before installing the next one. (Or if you prefer, in batches - just don't leave them hanging). Report technical problems at the Portal design talk page.

Fun activity #3: upgrade "Selected article" sections

These sections, where unmaintained, have gone stale. That's because 1) the excerpts are static, having been manually copied and pasted, and 2) because they lack automatic addition of new entries.

They can be upgraded with:

{{Transclude random excerpt}}

or

{{Transclude list item excerpt}}

or

{{Transclude linked excerpt}}

All three of these will provide excerpts that won't go stale. The latter two can provide excerpt collections that won't go stale, by providing new entries over time. The key is to select source pages or source sections that are frequently updated, such as root article sections, mainstream lists, or navigation templates.

Where will this put us?

When the above tasks are completed for the entire collection of portals (except the ones with specific maintainers), we'll be more than half-way done with the portal system upgrade.

Keep up the great work.    — The Transhumanist   19:08, 30 July 2018 (UTC)

Guideline and policy news

  • After a discussion at Meta, a new user group called "interface administrators" (formerly "technical administrator") has been created. Come the end of August, interface admins will be the only users able to edit site-wide JavaScript and CSS pages like MediaWiki:Common.js and MediaWiki:Common.css, or edit other user's personal JavaScript and CSS. The intention is to improve security and privacy by reducing the number of accounts which could be used to compromise the site or another user's account through malicious code. The new user group can be assigned and revoked by bureaucrats. Discussion is ongoing to establish details for implementing the group on the English Wikipedia.
  • Following a request for comment, the WP:SISTER style guideline now states that in the mainspace, interwiki links to Wikinews should only be made as per the external links guideline. This generally means that within the body of an article, you should not link to Wikinews about a particular event that is only a part of the larger topic. Wikinews links in "external links" sections can be used where helpful, but not automatically if an equivalent article from a reliable news outlet could be linked in the same manner.

Portals WikiProject update #016, 15 Aug 2018

Future portal tool

Discussions are underway on the design of a portal tool (user script) that will hopefully have features for modifying portals at the click of a menu item, to make editing them easier. It might do things like change the color for you, add to a selection, add a new section, move a section, and so on.

If you'd like to be involved and suggest features for the tool, please join us at Wikipedia talk:WikiProject Portals/Design#What would you want a portal tool to be able to do?.

Progress report: upgrade of portals

As new portal components are built by our Lua gurus, those components are being used to upgrade portals. Each component automates a section of a portal in a particular way.

The sections that are mostly upgraded so far are the Intro, and the Associated Wikimedia section.

The sections currently undergoing upgrade are: Selected image, Categories, and the Intro.

The Intro? Isn't that done already?

Yes, and no.

The upgrade of the excerpt in intros is mostly complete (there are about 70 non-standard portals that still need it).

Now we are doing another upgrade of intros in the form of adding a panoramic picture at the top of the intro, on portals for which such a picture is available on Commons:. Dozens of panoramas have been added so far, and they are really starting to affect the look of portals — the portals that have them look really good.

Regions are the most likely subjects to have panoramas, but a surprising number of other subjects have banner-shaped pictures too. Some examples of non-geographic portals that they have been added to are:

Speaking of pictures, several hundred Selected image sections have been upgraded to include image slideshows.

Progress report: design

The push for automation continues, with new components under continuous testing in the field. As problems are spotted, they are reported to our programmers, who have done a fantastic job of keeping up with bug reports and fixing the relevant Lua modules fast. I am highly impressed.

Construction time on new portals is now down to as little as a minute or less. Though not in general. If you are lucky enough to spot portals that fit the profile of the new tools (their strengths), then a portal can be complete almost as soon as it is created, with the added time it takes to find and add a panorama. Source page titles are not generally standardized, and so it source pages in many cases must be entered manually. Where source page titles follow a standard naming convention, portal creation for those subjects goes quickly.

So, we still have some hurdles, but the outlook on portals is very good. New features, and many improvements to features are on the horizon. I'll be sure to report them when they become available.

What will the portal of the future look like? That is up to you!

See you on the project's talk pages.

This issue is about portal creation...

Creating new portals

Myself and others have been testing and experimenting with the new components in upgrading existing portals and in building new portals. They have now been applied in hundreds of portals.

The templates are ready for general use for portal creation.

They are still a bit buggy, but the only way we are going to work the rest of the bugs out is by using them and reporting the bugs as we come across them.

I look forward to seeing what new portals you create!

Be sure to report bugs at WT:WPPORTD.

The main portal creation template is {{box portal skeleton}}.

Portal creation tips

After starting a portal using {{box portal skeleton}}...

  1. Placing a panorama (banner picture) at the top of the intro section is a nice touch, and really makes a portal look good. {{box portal skeleton}} doesn't automatically insert panoramas. So, you will need to do that by hand. They can be found at Commons:. For some examples, check out Portal:Sharks, Portal:Cheese, and Portal:Florence
  2. The search term provided in the Did you know? and In the news sections is very basic and rarely matches anything. It is best to replace that term with multiple search arguments, if possible (separate each argument with a pipe character). For example, in Portal:Capital punishment, see https://en.wikipedia.org/w/index.php?title=Portal:Capital_punishment&diff=855255361&oldid=855137403 Searches in templates use Lua search notation.
  3. Check the In the news and Did you know? sections for mismatches. That is, sometimes entries come up that shouldn't be displayed. If there are any, refine the search strings further, so they don't return such results.
  4. Finish each portal you've created before creating a new one. We don't want unfinished portals sitting around.

Need a laugh?

renamed Optimist on the run → Voice of Clam

Interface administrator changes

added Amorymeltzer • Mr. Stradivarius • MusikAnimal • MSGJ • TheDJ • Xaosflux

Guideline and policy news

  • Following a "stop-gap" discussion, six users have temporarily been made interface administrators while discussion is ongoing for a more permanent process for assigning the permission. Interface administrators are now the only editors allowed to edit sitewide CSS and JavaScript pages, as well as CSS/JS pages in another user's userspace. Previously, all administrators had this ability. The right can be granted and revoked by bureaucrats.

Technical news

  • Because of a data centre test you will be able to read but not edit the wikis for up to an hour on 12 September and 10 October. This will start at 14:00 (UTC). You might lose edits if you try to save during this time. The time when you can't edit might be shorter than an hour.
  • Some abuse filter variables have changed. They are now easier to understand for non-experts. The old variables will still work but filter editors are encouraged to replace them with the new ones. You can find the list of changed variables on mediawiki.org. They have a note which says Deprecated. Use ... instead. An example is article_text which is now page_title.
  • Abuse filters can now use how old a page is. The variable is page_age.

Arbitration

  • The Arbitration Committee has resolved to perform a round of Checkuser and Oversight appointments. The usernames of all applicants will be shared with the Functionaries team, and they will be requested to assist in the vetting process. The deadline to submit an application is 23:59 UTC, 12 September, and the candidates that move forward will be published on-wiki for community comments on 18 September.

Welcome AmericanAir88

Give a hearty welcome to AmericanAir88, who has adopted working on portals as one of his main purposes on Wikipedia. So far, he has created the following portals:

Way to go!

Where's Evad?

Evad disappeared from Wikipedia on October 18.

He has been, and will continue to be, sorely missed.

Hopefully, he is okay, on a Caribbean cruise or something.

The conversion continues

Portals of the old design, are slowly but surely being converted to the new single-page design.

One factor that has slowed things down is that for many sections, the section header call and section contents call are integrated into a template and buried in a lua module, locking them in on each portal. They have been that way for years.

This means that these sections can't be directly edited like the other sections on the same portal. So, search/replaces affect all the sections except those. So, upgrading headers on these portals, for example, misses the integrated sections and inadvertently results in 2 different header colors.

Before we can continue with the upgrade of these portals, the headers and section contents calls need to be restored to each portal, so that those can be edited in concert with the other sections on the portal, and worked on independently of each other.

This is underway, with a solution implemented on about 1/4 of the affected portals so far. Around 300 of them. The remaining 900 should be done within a couple weeks or so.

Going wide...

We now have banner-shaped pictures included in the introduction sections of 180 portals. The rarity of such pictures has made it difficult to find suitably narrow images for display across the tops of portals.

We have a solution for this, courtesy of FR30799386...

Most pictures are not banner-shaped. But, you can still use them as banners. Here's how:

{{Portal image banner|File:Blueberries .jpg |maxheight=120px |overflow=Hidden }}

Using both maxheight=120px and overflow=Hidden produces this:

Project's status

There are now 4,140 portals, with more being created almost daily. Prior to this project's reboot, portals were created at about the rate of 80 per year. Since April of this year, we've created about 2,600 new portals, or 32.5 years' worth at the old rate.

Of those new portals, about 3/4 of them need links leading to them. Almost all of them are linked to from the category system, but they still need links in article see also sections, at the bottom of navigation templates, and on the main portals list at Portal:Contents/Portals.

Of the 1500 portals created before the reboot, about 300 have been completely converted to the new design so far. About 1100 more have been partially converted, with intros, image slideshows, and associated wikimedia sections getting the most attention.

Discussion has resumed on the portal guidelines.

Until next issue...

See ya round the portal system!    — The Transhumanist   11:40, 11 November 2018 (UTC)
