Portals WikiProject update #010, 30 June 2018

We've grown to 94 participants.

A warm welcome to dcljr and Kpgjhpjm.

Rating system for portals

We are in the process of developing a rating system specifically for portals, as the quality assessment scheme for articles does not apply to portals. It is coming along nicely. Your input would be very helpful. See the discussion at

Wikipedia talk:WikiProject Portals/General#Proposed new quality class assessments
.

Better than a barnstar

One of our participants got involved with this WikiProject through interest in how the new generation of portals would be handled in WP's MOS (Manual of Style). It didn't take long before he got sucked in deeper. This has given him an opportunity to look around, and so, he has made an assessment of this WikiProject's operations:

I'm quite frankly really impressed and inspired by what's happening here. If you'd asked me a year ago if I thought portals should just be scrapped as a failed, dragged-out experiment, I would have said "yes". This planning and the progress toward making it all practical is exemplary of the wiki spirit, in particular of a happy service-to-readers puppy properly wagging its technological and editorial tail instead of the other way around, and without "drama". It's also one of the few examples I've seen in a long time of a new wikiproject actually doing something useful and fomenting constructive activity (instead of acting as a barrier to participation, and a canvassing/ownership farm for PoV pushers). Kudos all around. — SMcCandlish

Congratulations, everyone. Keep up the great work.

Slideshow development

We've run into a glitch with slideshows: they don't work on mobile devices.

Initially, we will need to explore options that allow portals to have slideshows without adversely affecting mobile viewers. See

Wikipedia talk:WikiProject Portals/Design#Mobile view support
.

Eventually, we may need another way to do slideshows. If we do go this route, and I don't see why we wouldn't, then (user configurable) automatic slideshows also become a possibility.

TemplateStyles RfC passed

Once implemented, this will allow editors to create and edit cascading style sheets for use with templates. This will expand what we can do with portals. For more detail, see mw:Extension:TemplateStyles and Wikipedia:TemplateStyles.

Automation effort

We've run into an obstacle using Lua-based selective transclusion: Lua is incapable (on Wikipedia) of reading in article names from categories. Because of this, we'll need to seek other approaches for fully automating the Selected article section. We are exploring sources other than categories, and other technologies besides Lua.

Speaking of using other sources, the template {{Transclude list item excerpt}} collects list items from a specified page, or from a section of that page, and transcludes the lead from a randomly selected link from that list. Courtesy of Certes. So, if you use this in a portal, and if the template specifies a page or section serviced by JL-Bot, you've now got yourself an automatically updated section in the portal. JL-Bot provides links to featured content and good articles, by subject.

What is "fully automated"? When you create a portal using a creation template, and the portal works thereafter without editor intervention, the portal is fully automated. That is, the portal is supported by features that fetch new content. If you have to add new article names every so often for it to display new content, then it is only semi-automated.

Currently, the Selected article section is semi-automated, because it requires that an editor supplies the names of the various articles for which excerpts are (automatically) displayed. For examples, look at the wikisource code of

Portal:Ancient Tamil civilization, and Portal:Reference works
.

So far, 3 sections are fully automatable: the introduction section, the categories section, and the Associated Wikimedia section.

Where is all this heading?

Henry.

Or some other name.

Eventually, the portal department will be a software program. And we won't have to do anything (unless we want to). Not even tell it what portals to create (unless we want to). It will just do it all (plus whatever else we want it to do). And we will of course give it good manners, and a name.

But, that is a few years off.

Until then, building portals is still (partially) up to us.    — The Transhumanist   13:31, 30 June 2018 (UTC)

WikiCup 2018 July newsletter

The third round of the 2018 WikiCup has now come to an end. The 16 users who made it to the fourth round had at least 227 points. Our top scorers in round 3 were:

  • South Carolina Courcelles, a first time contestant, with 1756 points, a tally built largely on 27 GAs related to the Olympics
  • Scotland Cas Liber, our winner in 2016, with two featured articles and three GAs on natural history and astronomy topics
  • Cascadia (independence movement) SounderBruce, a finalist last year, with a variety of submissions related to transport in the state of Washington

Contestants managed 7 featured articles, 4 featured lists, 120 good articles, 1 good topic, 124 DYK entries, 15 ITN entries, and 132 good article reviews. Over the course of the competition, contestants have completed 458 GA reviews, in comparison to 244 good articles submitted for review and promoted. As we enter the fourth round, remember that any content promoted after the end of round 3 but before the start of round 4 can be claimed in round 4. Please also remember that you must claim your points within 14 days of "earning" them. When doing GARs, please make sure that you check that all the GA criteria are fully met. Please also remember that all submissions must meet core Wikipedia policies, regardless of the review process; several submissions, particularly in abstruse or technical areas, have needed additional work to make them completely verifiable.

If you are concerned that your nomination—whether it is at good article nominations, a featured process, or anywhere else—will not receive the necessary reviews, please list it on

Wikipedia:WikiCup/Reviews Needed (remember to remove your listing when no longer required). Questions are welcome on Wikipedia talk:WikiCup, and the judges are reachable on their talk pages or by email. Good luck!

Guideline and policy news

Technical news

  • Starting on July 9, the WMF Security team, Trust & Safety, and the broader technical community will be seeking input on an upcoming change that will restrict editing of site-wide JavaScript and CSS to a new technical administrators user group. Bureaucrats and stewards will be able to grant this right per a community-defined process. The intention is to reduce the number of accounts who can edit frontend code to those who actually need to, which in turn lessens the risk of malicious code being added that compromises the security and privacy of everyone who accesses Wikipedia. For more information, please review the FAQ.
  • Syntax highlighting has been graduated from a Beta feature on the English Wikipedia. To enable this feature, click the highlighter icon () in your editing toolbar (or under the hamburger menu in the 2017 wikitext editor). This feature can help prevent you from making mistakes when editing complex templates.
  • IP-based cookie blocks should be deployed to English Wikipedia in July (previously scheduled for June). This will cause the block of a logged-out user to be reloaded if they change IPs. This means in most cases, you may no longer need to do /64 range blocks on residential IPv6 addresses in order to effectively block the end user. It will also help combat abuse from IP hoppers in general. For the time being, it only affects users of the desktop interface.

Portals WikiProject update #011, 10 July 2018

We now have 97 participants.

Be sure to welcome our newest members,

BrantleyIzMe, Coffeeandcrumbs, and Nolan Perry
, with warm regards.

Work is proceeding apace. We have 2 major thrusts right now: converting the intro sections of portals, and building the components of the one-page automated model...

Converting the intro sections

We need everybody, except those building software components, to work on converting intros. If you have AWB, definitely use that. If not, then work on them manually. Even one a day, or as often as you can muster, will help a lot. There are only about 1,000 of them left to go, so if everyone chips in, it will go pretty quickly. Remember, there are 97 of us!

The intros for most of the portals starting with A through F have already been converted to use the {{Transclude lead excerpt}} template.

The standard wikicode for the automated intro that we want to put into place looks like this:

{{/box-header|Introduction|noedit=yes|}}
{{Transclude lead excerpt | {{PAGENAME}} | paragraphs=1-2 | files=1}}
{{Box-footer|[[{{PAGENAME}}|Read more...]]}}

That works for most portals, but not all. For some portals it requires some tweaking, and for others, we may have to use a different or more customized approach. Remember to visually inspect each portal you work on and make sure that it works before moving on to the next one.

Be sure to skip user-maintained portals. They are listed at Wikipedia:WikiProject_Portals#Specific_portal_maintainers.

AWB tips

I've started an AWB tips page, for those of you feeling a bit overwhelmed by that power user tool. Feel free to add to it and/or improve it.

Portal automation

We have some very talented Lua programmers, who are pushing the limits of what we can do in gathering data from Wikipedia's various namespaces and presenting it in portals. Due to their efforts, Lua is powering the selective transclusion core of our emerging automated portal design, in the form of selected article sections that rotate content, and slideshows.

To go beyond Lua's limits, to take full advantage of Mediawiki's API, we are in the midst of adding another programming language to the resources we shall be making use of: JavaScript. The ways that JavaScript can help us edit portals to boost the power of our Lua solutions, are being explored, which will likely make the two languages synergistic if not symbiotic. Research is under way on how we can use JavaScript to make some of the portal semi-automated features fully automatically self-updating, in ways that Lua cannot. Like gathering random members from a category and inserting them into a portal's templates as parameters. Once the parameters are in place, Lua does the rest.

If you would like to get involved with design efforts, or just keep up on them, see

Wikipedia talk:WikiProject Portals/Design
.

When should we start building new portals?

Well, not at the present time, because building portals is quite time consuming. The good news is that we are working on a design that will be fully automated, or as close to that as we can get. And the new design is being implemented in the portal department's

main portal creation template
. This means, that not only will portals update themselves, their creation will be highly automated as well. That's the nature of templates. You put them in place, and they just... work.

What I'm getting at here, is that it would be better to wait to build lots of new portals until after the new design is completed. Because with it, instead of taking hours to create a new portal, it will likely take minutes.

That does not mean we should be idle in the meantime. The main reason most of us are here is because it became apparent that portals were largely unmaintained and had grown out-of-date. This had become so apparent that a proposal was made to delete all the portals and the portal namespace to boot. That makes our main objective in the short term to improve all the existing portals so that the community will want to keep them—forever.

Building lots of new portals comes later. Let's fix up the ones we have first. ;)

And on that note, I bid you adieu. Until next newsletter, see ya 'round the WikiProject.    — The Transhumanist   12:30, 10 July 2018 (UTC)

Portals WikiProject update #012, 15 July 2018

We have 97 participants.

Getting faster

Automation makes things go faster, even portal creation. One of the components Certes made was {{Transclude list item excerpt}}. I became curious about its possible applications.

So I worked out a portal design using it, the initial prototypes being Portal:Kyoto (without a "Selected pictures" section), and Portal:Dubai (with a "Selected pictures" section). Then I used Portal:Dubai as the basis for further portals of this type...

I was able to revamp Portal:Munich from start to finish in less than 22 minutes.
Portal:Dresden took about 19 minutes.
Portal:Athens took less than 17 minutes.
Did Portal:Florence in about 13 minutes.
Portal:Stockholm also in about 13.
Portal:Palermo approx. 12 minutes.

Why?

To see, and to show, what may become feasible via automation.

It now looks highly feasible that we could get portal construction time down to a few minutes, or maybe even down to a few seconds.

The singularity is just around the corner. :)

Slideshows

When using the {{Random slideshow}} template to display pictures, be sure to use the plural tense in the section title: "Selected pictures". That's because slideshows don't show up on many mobile devices. Instead the whole set of pictures is shown, hence the section title "Selected pictures", as it fits both situations.

In case you are curious, here is a list of the portals so far that have a slideshow:

Progress on intro conversions

The intros for most of the portals up through the letter "O" have been converted, using this wikicode:

{{/box-header|Introduction|noedit=yes|}}
{{Transclude lead excerpt | {{PAGENAME}} | paragraphs=1-2 | files=1}}
{{Box-footer|[[{{PAGENAME}}|Read more...]]}}

Where the pagename didn't match the article title for the subject, the title was typed in.

Most of the portals that do not contain {{/intro}} or {{{{FULLPGENAME}}/Intro}} have not yet been processed.

About a thousand portals use the method of selective transclusion for the intro section. That's about two-thirds. That means we have one-third of the way to go on the intro section conversions.

Much more to come...

So much has been happening with portals that I can't keep up with it. (That's good). Which means, more in the upcoming issue. Until then, see ya 'round the project. Sincerely,    — The Transhumanist   08:45, 15 July 2018 (UTC)

Portals WikiProject update #013, 18 July 2018

I got overwhelmed IRL (in real life) during the production of issue #12. So, here is a catch-up issue, to help bring you (and me) up to speed on what is happening with portals...

By the way, we still have 97 participants. (Tell all your friends about this WikiProject, and have them join!)

Panoramas!

One cool feature of some of the geographical portals is a panoramic picture at the top of the intro section.

Check these out:

The Portals WikiGnome squadron is busy adding panoramas to geographical portals that don't yet have one. Feel free to join in on the fun. See task details at Wikipedia:WikiProject Portals#Add a panorama or skyline to a geographic portal.

Caveat: avoid super-huge pics, as they can cause portal scripts to time-out. Please try to keep picture size down below 2 megabytes. Thank you.

Auto-populated slideshows

Speaking of pictures...

We now have two slideshow templates. You may be familiar with {{Random slideshow}}, in which the editor types in (or copies/pastes) a list of pictures he or she wants it to display.

Well, now we have another template, courtesy of Evad37, which accepts one or more page names instead, and displays a random image off of the listed pages. So instead of listing dozens of files by hand, you can include a title or three to be scanned automatically. It even lets you specify particular sections.

The new slideshow template is {{Transclude files as random slideshow}}.

Here's a sample, that grabs images from a single page:

Selected motorcycle or motorcycling pictures

New Template:Box-header colour

Speaking of new templates, here's another one!

Also from Evad37, we have a new component for starting section boxes, that is color configurable, and that bypasses the need for box-header subpages altogether. It is {{Box-header colour}}.

For color support, see Web colors.

For the discussion in which this was inspired, see

Wikipedia talk:WikiProject Portals/Tasks#Colour combinations for accessibility
.

(In case you didn't notice, the slideshow box above uses this new template).

BTW, don't forget to close your box with {{Box-footer}}.

Where are we on the redesign?

The answer to this question is quite involved, and would fill this page to overflowing. Therefore, this subject, including a complete update on where we are at and where we are going with portal design, is covered at

Wikipedia talk:WikiProject Portals/Design
.

Where are we on portal conversion?

An AWB pass to convert intros on the portals has been completed. The pass couldn't convert them all (due to various formatting configurations, etc.).

All but about 170 portals now have introductions selectively transcluded on the base page. Not counting manually maintained portals, that leaves about 70 portals that either need their intros converted, or they need an intro.

Next, we'll be converting the categories sections!

What's the plan, man?

The course of action we have been taking goes something like this, with all steps being pursued simultaeneously...

1) Design a one-page automated portal model

2) Convert existing portals to that design (except those being manually maintained)

3) Remove subpages no longer needed

4) Develop further tools to empower editors working on portals

Later, when the tools are up to the task, filling in the gaps in coverage (with new portals) will also become practical.

Are we caught up yet?

Probably not.

Who knows what our programmers and editors have dreamed up while I was writing this.

One of nomination Kepelino recently failed because it was ruled as too short. The funny thing is it is longer than a few of my other GA articles. I don't think there is a criteria on length for the article given there are articles like Guttorm of Norway, East 233rd Street (Bronx), and Shades of Cool just to name a few.

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

Amphibian types

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 3 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.

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 3 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.

Notice how the box bottoms line up. That readjusts even if you click the slideshow buttons.

The template used for this is {{Flex columns}}.

By the way, when you include more than one box in a column, any left over whitespace in that column is divided between them.

Box-header colour

You may have noticed the new {{Box-header colour}} template used above. It lets you pick the color locally (right on the same page). Before, this was handled on a subpage somewhere.

Testing, testing

Now that we have lots of toys to play with for making cool portals...

Don't forget, that the majority of views of Wikipedia these days are from mobile devices. We need to make certain that portals display well on those. So, remember to check your work on portals in mobile view mode...

To see a portal in mobile view mode, insert a ".m" into a portal's url, after "en", like this:

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)

NPR Newsletter No.12 30 July 2018

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

Hello Iazyges/Archives/2018, 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:

{{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 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 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".

  • Image 4The 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.

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   19:12, 30 July 2018 (UTC)
