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:

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

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.

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

Clockwise from top left: veiled chameleon (Chamaeleo calyptratus), rock monitor (Varanus albigularis), common blue-tongued skink (Tiliqua scincoides), Italian wall lizard (Podarcis sicula), giant leaf-tailed gecko (Uroplatus fimbriatus), and legless lizard (Anelytropsis papillosus)

Lizard is the common name used for all squamate reptiles other than snakes (and to a lesser extent amphisbaenians), encompassing over 7,000 species, ranging across all continents except Antarctica, as well as most oceanic island chains. The grouping is paraphyletic as some lizards are more closely related to snakes than they are to other lizards. Lizards range in size from chameleons and geckos a few centimeters long to the 3-meter-long Komodo dragon. (Full article...)

Blanus cinereus, Spain

Amphisbaenia /æmfɪsˈbiːniə/ (called amphisbaenians or worm lizards) is a group of typically legless lizards, comprising over 200 extant species. Amphisbaenians are characterized by their long bodies, the reduction or loss of the limbs, and rudimentary eyes. As many species have a pink body and scales arranged in rings, they have a superficial resemblance to earthworms. While the genus Bipes retains forelimbs, all other genera are limbless. Phylogenetic studies suggest that they are nested within Lacertoidea, closely related to the lizard family Lacertidae. Amphisbaenians are widely distributed, occurring in North America, Europe, Africa, South America, Western Asia and the Caribbean. Most species are less than 6 inches (15 cm) long. (Full article...)

Turtles from different families; clockwise from top-left: Red-bellied short-necked turtle, Indian flapshell turtle, Hawksbill sea turtle, and Galápagos tortoise

Turtles, or testudines, are reptiles of the order Testudines, characterized by a special shell developed mainly from their ribs. Modern turtles are divided into two major groups, the Pleurodira (side necked turtles) and Cryptodira (hidden necked turtles), which differ in the way the head retracts. There are 360 living and recently extinct species of turtles, including land-dwelling tortoises and freshwater terrapins. They are found on most continents, some islands and, in the case of sea turtles, much of the ocean. Like other amniotes (reptiles, birds, and mammals) they breathe air and do not lay eggs underwater, although many species live in or around water. (Full article...)

Nile crocodile (Crocodylus niloticus)

Crocodiles (family Crocodylidae) or true crocodiles are large semiaquatic reptiles that live throughout the tropics in Africa, Asia, the Americas and Australia. The term crocodile is sometimes used even more loosely to include all extant members of the order Crocodilia, which includes the alligators and caimans (family Alligatoridae), the gharial and false gharial (family Gavialidae) among other extinct taxa.

An American alligator (top) and a Chinese alligator

An alligator, or colloquially gator, is a large reptile in the genus Alligator of the family Alligatoridae of the order Crocodilia. The two extant species are the American alligator (A. mississippiensis) and the Chinese alligator (A. sinensis). Additionally, several extinct species of alligator are known from fossil remains. Alligators first appeared during the late Eocene epoch about 37 million years ago. (Full article...)

Aldabra giant tortoise
(Aldabrachelys gigantea)

Tortoises (/ˈtɔːr.təs.ɪz/) are reptiles of the family Testudinidae of the order Testudines (Latin for "tortoise"). Like other turtles, tortoises have a shell to protect from predation and other threats. The shell in tortoises is generally hard, and like other members of the suborder Cryptodira, they retract their necks and heads directly backward into the shell to protect them. (Full article...)

Pope's pit viper (Trimeresurus popeiorum)

Snakes are elongated, limbless, carnivorous reptiles of the suborder Serpentes (/sɜːrˈpɛntiːz/). Like all other squamates, snakes are ectothermic, amniote vertebrates covered in overlapping scales. Many species of snakes have skulls with several more joints than their lizard ancestors, enabling them to swallow prey much larger than their heads (cranial kinesis). To accommodate their narrow bodies, snakes' paired organs (such as kidneys) appear one in front of the other instead of side by side, and most have only one functional lung. Some species retain a pelvic girdle with a pair of vestigial claws on either side of the cloaca. Lizards have independently evolved elongate bodies without limbs or with greatly reduced limbs at least twenty-five times via convergent evolution, leading to many lineages of legless lizards. These resemble snakes, but several common groups of legless lizards have eyelids and external ears, which snakes lack, although this rule is not universal (see Amphisbaenia, Dibamidae, and Pygopodidae).

Yacare caiman, Caiman yacare

A caiman (/ˈkeɪmən/; also cayman as a variant spelling from Taíno kaiman^{[additional citation(s) needed]}) is an alligatorid belonging to the subfamily Caimaninae, one of two primary lineages within the Alligatoridae family, the other being alligators. Caimans are native to Central and South America and inhabit marshes, swamps, lakes, and mangrove rivers. They have scaly skin and live a fairly nocturnal existence. They are relatively small-sized crocodilians with an average maximum weight of 6 to 40 kg (13 to 88 lb) depending on species, with the exception of the black caiman (Melanosuchus niger), which can grow more than 4 m (13 ft) in length and weigh in excess of 1,000 kg (2,200 Ib). The black caiman is the largest caiman species in the world and is found in the slow-moving rivers and lakes that surround the Amazon basin. The smallest species is the Cuvier's dwarf caiman (Paleosuchus palpebrosus), which grows to 1.2 to 1.5 m (3.9 to 4.9 ft) long. There are six different species of caiman found throughout the watery jungle habitats of Central and Southern America. The average length for most of the other caiman species is about 2 to 2.5 m (6.6 to 8.2 ft) long. (Full article...)

Male gharial

The gharial (Gavialis gangeticus), also known as gavial or fish-eating crocodile, is a crocodilian in the family Gavialidae and among the longest of all living crocodilians. Mature females are 2.6 to 4.5 m (8 ft 6 in to 14 ft 9 in) long, and males 3 to 6 m (9 ft 10 in to 19 ft 8 in). Adult males have a distinct boss at the end of the snout, which resembles an earthenware pot known as a ghara, hence the name "gharial". The gharial is well adapted to catching fish because of its long, narrow snout and 110 sharp, interlocking teeth. (Full article...)

European fire-bellied toad (Bombina bombina), a member of the family Bombinatoridae

Toad is a common name for certain frogs, especially of the family Bufonidae, that are characterized by dry, leathery skin, short legs, and large bumps covering the parotoid glands.

A distinction between frogs and toads is not made in scientific taxonomy, but is common in popular culture (folk taxonomy), in which toads are associated with drier, rougher skin and more terrestrial habitats. (Full article...)
Image 2

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 (coming from the Ancient Greek ἀνούρα, literally 'without tail'). 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.

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. Urodela is a scientific Latin term based on the Ancient Greek οὐρά δήλη: ourà dēlē "conspicuous tail". Caudata is the Latin for "tailed ones", from cauda : "tail".

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.

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.

https://en.m.wikipedia.org/wiki/Portal:Reptile

If you discover problems in a portal you can't fix, report them on Wikipedia talk:WikiProject Portals/Design.

Until next time...

Have fun. — The Transhumanist 00:58, 27 July 2018 (UTC)[reply]

What percentage of WP viewing is from mobile devices?

Someone asked me for a reference on this.

You wouldn't happen to know the link to this statistic, would you?

Thank you, — The Transhumanist 00:39, 28 July 2018 (UTC)[reply]

@The Transhumanist: Sitewide, for the latest 20 days, there were approx 5,000,000,000 user views totals, including approx 2,200,000,000 on desktop, 86,000,000 on mobile apps and 2,700,000,000 on mobile web. So roughly 44% desktop, 54% mobile web, and 2% mobile apps. However, that's probably heavily biased towards mainspace, and certain pages in mainspace. For individual pages there's huge variation, e.g for Portal:Lithuania there's 552 total, of which 502 are on desktop (91%). There's a link to pageview stats at the top of history pages. - Evad37 [talk] 01:17, 28 July 2018 (UTC)[reply]

Thank you. By sitewide, you are referring to the English Wikpedia, and not all the language versions, right? — The Transhumanist 01:30, 28 July 2018 (UTC)[reply]

Yes, just English Wikpedia - Evad37 [talk] 01:37, 28 July 2018 (UTC)[reply]

NPR Newsletter No.12 30 July 2018

Chart of the New Pages Patrol backlog for the past 6 months. (Purge)

Hello Evad37, thank you for your work reviewing New Pages!

June backlog drive

Overall the June backlog drive was a success, reducing the last 3,000 or so to below 500. However, as expected, 90% of the patrolling was done by less than 10% of reviewers.
Since the drive closed, the backlog has begun to rise sharply again and is back up to nearly 1,400 already. Please help reduce this total and keep it from raising further by reviewing some articles each day.

New technology, new rules

New features are shortly going to be added to the Special:NewPagesFeed which include a list of drafts for review, OTRS flags for COPYVIO, and more granular filter preferences. More details can be found at this page.
Probationary permissions: Now that PERM has been configured to allow expiry dates to all minor user rights, new NPR flag holders may sometimes be limited in the first instance to 6 months during which their work will be assessed for both quality and quantity of their reviews. This will allow admins to accord the right in borderline cases rather than make a flat out rejection.
Current reviewers who have had the flag for longer than 6 months but have not used the permissions since they were granted will have the flag removed, but may still request to have it granted again in the future, subject to the same probationary period, if they wish to become an active reviewer.

Editathons

Editathons will continue through August. Please be gentle with new pages that obviously come from good faith participants, especially articles from developing economies and ones about female subjects. Consider using the 'move to draft' tool rather than bluntly tagging articles that may have potential but which cannot yet reside in mainspace.

The Signpost

The next issue of the monthly magazine will be out soon. The newspaper is an excellent way to stay up to date with news and new developments between our newsletters. If you have special messages to be published, or if you would like to submit an article (one about NPR perhaps?), don't hesitate to contact the editorial team here.

Portals tasks requests: presented in the newsletter below...

Portals WikiProject update #015, 31 July 2018

Now that we have lots of toys to play with, it's play time!

Here are some fun activities to use our new toys on...

Fun activity #1: put the improved panorama template to use

Would you like to travel around the world? Well, this may be the next best thing...

Here's another fun toy to play with: {{Portal image banner}}

To see what it looks like, check out the panoramas at the tops of the following portals:

The task: There are many geography portals that lack panoramas. Please add some. 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:

and

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 1A discus (Symphysodon discus) is guarding its eggs. As for most cichlids, brood care is highly developed with both the parents caring for the young. Additionally, adult discus produce a secretion through their skin, off which the larvae live during their first few days.
Image 2The red lionfish (Pterois volitans) is a venomous coral reef fish from the Indian and western Pacific Oceans. The red lionfish is also found off the east coast of the United States, and was likely first introduced off the Florida coast in the early to mid 1990s.
Image 3Koi 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".
Image 4Salmon 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.

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:

or

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 19:10, 30 July 2018 (UTC)[reply]

Publishing script error

I wonder why [1] was necessary? ☆ Bri (talk) 02:08, 1 August 2018 (UTC)[reply]

@Bri: This edit [2] added {{Wikipedia:Wikipedia Signpost/Templates/RSS description|1=Title}}, and it was still there when it was published. If there's an existing value in the RSS description, the script won't override it. - Evad37 [talk] 02:17, 1 August 2018 (UTC)[reply]

That makes sense then. We had to re-do that feature when a new topic was selected. ☆ Bri (talk) 02:41, 1 August 2018 (UTC)[reply]
