Sure, radioactive-spider bite powers are cool and all. But imagine having the superpowers of a worm-snail. The new species Thylacodes vandyensis, reported Wednesday in the journal PeerJ, is getting compared to the superhero—as if we didn’t have enough spidermen running around already.

Just as Peter Parker shoots super-strong spider silk from his wrists (or something), this stationary, sea-dwelling worm-snail spews mucus from its “giant slime glands”.

And oh, what marvelous slime glands they are.

“Normally, snails produce a trail of slime so that they can glide on it in order to move,” lead study author Rüdiger Bieler, Curator of Invertebrates at Chicago’s Field Museum, said in a statement. “But worm-snails are stationary—what did they need slime glands for?”

Fighting crime, duh. Or hunting, anyway. As Bieler noted, worm-snails are homebodies. They attach their tube-shaped shells to a hard surface like a rock or reef not long after they hatch, and that’s that. It’s hard to be much of a vigilante when you spend your adult life stuck to a rock, but Thylacodes vandyensis uses its glands to produce edible mucus nets to rope in dinner.

“The snails have an extra pair of tentacles down near the base of their body, almost like little arms. These tentacles are what they use to shoot slime,” Bieler said. “They shoot out a mucus web, just like Spiderman—although in slow motion. Then, microorganisms get stuck in the web, and the snails use their mouths to pull the web back in and strain the food through barbs on their tongues called radulae in order to eat. They filter-feed, much like baleen whales.”

While this is a new species, don’t get too excited about these sedentary web-spewing snails: cute as they may be (if you think snot webs are cute, we don’t blame you), the worm-snails are a sign that a desperate attempt to protect the world’s coral reefs may be in danger.

So far, the creatures have only ever been found on the wreck of the USNS General Hoyt S. Vandenberg, a ship deliberately sunk as part of the “Key West Ghost Fleet”. The ship, sunk in 2009, is the second-largest artificial reef in the world. It and other retired ships provide a clean surface for sponges, corals, and hydroids to grow, which in turn provide food for local fish and attract fishermen and tourists. Artificial reefs represent just one of many attempts to support natural coral populations, which are dwindling due to climate change, pollution, and interference from tourists.

“We’re trying to figure out what really belongs here,” Bieler told the Miami Herald. “Are we really seeing the native butterflies returning? Or are we seeing feral cats? In the marine environment, it’s a little tough to know who are the feral cats.” Bieler, who’s familiar with the local fauna, is fairly certain that Thylacodes vandyensis isn’t a Floridian who’s gone unnoticed for the researcher’s entire career. Using DNA data banks from museum collections as a guide, Bieler and his colleagues were able to track down the worm-snail’s closest relative—and unfortunately, it hails from the Pacific ocean.

That’s not a huge surprise: other Pacific species have been seen colonizing the artificial reefs in that area. And because artificial reefs start out fresh—they don’t have any local coral or other species growing on them when they’re sunk—it’s easy for invasive species to get in on the ground floor and flourish. Live Science reports that just a handful of the snails were stuck to the ship in 2012, but the reef was flooded with thousands of them just a couple of years later. And it’s not just that worm-snails take away resources from other, native critters: they can actually reduce coral growth, and are known to occasionally carry blood flukes—parasites that attack the endangered loggerhead sea turtle.

“The artificial reefs could serve as the canary in the coal mine,” Bieler said in a statement. “If we monitor their presence on the shipwrecks, we can keep tabs on them and potentially stop them from spreading to the living reefs.”

Difference Between Ocean And Sea


Earth is distinctive in its abundance of water and there are several water bodies on the earth including rivers, lakes, seas, oceans, gulfs, streams, and more. Oceans are large water bodies and cover the majority of the area on the earth. These are significant in various aspects such as marine ecosystems, weather, aquatic trade, and world exploration, and two million species existing in the oceans that have specific adaptations and life. Oceans and seas play a vital role in weather and climate patterns and they contribute some ecological functions and supply food, medicine, and other needs for humans. They both share differences and few similarities.

The ocean is a huge body of salt water and it is deep and wide. It covers nearly 71% of the surface of the earth and has a depth of approximately 3688 meters. The average temperature of the ocean is 80°F, however, it gradually decreases to the poles from the equator.


Earth had been formed around 4.6 billion years ago and it slowly began to separate into two layers as a lighter and heavier rock. Carbon dioxide and other gases formed the atmosphere of the earth. Earth’s crust has formed from lighter rock and Earth’s core has formed from heavy rock. The water for the ocean came from the inside of the rocks. The molten rocks get cooled and release gases and water vapour. This water vapour condensed and covered the crust by forming the oceans.


Pure water is ideally clear, however, the water appears as a deep navy blue in oceans. It is because there is a lot of water in the oceans and the water is so deep that there are no reflections off the seafloor. The blue colour is because of the absorption and scattering of light. The scattering of blue wavelengths of light is the same as the scattering of blue light in the sky and the absorption is a huge factor for the colour than scattering.


The global ocean is divided into five recognizable oceans such as Pacific, Atlantic, Indian, Arctic, and Southern. The first three oceans are commonly known oceans and the last is the newly named ocean. The Pacific Ocean is the largest in the world. The boundaries between these regions have developed for several causes such as geographical, historical, scientific, and cultural aspects. The living creatures in the oceans include seabirds, small invertebrates, sharks, shellfish, seahorses, etc.


Sea is a portion of the ocean that is a continuous body of salt water and it exists between areas where these are meeting oceans and land. The salinity of the seawater is based on precipitation, evaporation, and river discharge. The temperature of the surface of the seawater is 86°F and it is 30°F at the sea bed.

Major seas

There are above 50 seas on the earth such as the Arabian Sea, Red Sea, Yellow Sea, Aral Sea, Caspian Sea, Mediterranean Sea, Caribbean Sea, Black Sea, South China Sea, and more. The Philippine Sea is the largest in the world and there are three major types of seas −

Nearly enclosed seas

These seas are deep into continents, which are joined with the open ocean by narrow canals called straits and are almost landlocked with a small range of tides. It includes the Baltic Sea and the Mediterranean sea. There is a slight exchange of water between the open ocean and the enclosed sea. The Red sea is saltier than the Indian ocean and coral reefs such as sea turtles, sea horses, and clownfish are adapted to their life in this sea.

Partly or semi-enclosed seas

These seas are similar to the ocean and the Weddell sea of Antarctica is connected by a wide opening to the ocean. The organisms and waves of the Weddell sea are the same as the organisms and waves of the Atlantic ocean. The South China sea also comes under a partly enclosed sea.

Hypersaline lakes

Some seas have excessive high salt content in the water, therefore, it is called hypersaline lakes. The Caspian Sea is a landlocked sea that is situated between Asia and Europe. The southern part of the sea in Iran and Turkmenistan has excessive salt content. A hypersaline lake, the Dead Sea is located between Jordan and Israel.

Similarities between ocean and sea

Ocean and Sea are important for 50% of oxygen production on the earth.

These both are large bodies of saltwater.

These are breeding grounds for several marine animals and plants.

Differences between the ocean and sea

Ocean Sea

The ocean is larger

Sea is smaller than the ocean

There are no landlocked oceans in the world

There are landlocked seas in the world

Oceans do not have enclosed oceans

Seas have enclosed seas

Deeper ocean

Less deep than oceans

Marine creatures in the ocean are less dependent on sunlight such as whales, phytoplankton, etc.

Marine creatures in the sea are more dependent on sunlight such as crabs, lobsters, etc.


Ocean and sea both are huge water bodies on the earth. The ocean is salty water and the sea is a part of the ocean. They are developed from molten rocks by the condensation of water vapour. The Pacific Ocean is the largest present on the earth. The colour of the sea or ocean water depends on the absorption and scattering of light. It is usually blue because of the scattering of blue light in the sky. Sea is categorised into three types depending on the salinity and enclosed area. The Philippine Sea is the largest and there are several seas present in the world.


Q1. When does a sea become an ocean?

Ans. A sea becomes an ocean when it reaches an opening where it is enclosed by land on most of its sides and connected with the larger water body.

Q2. What are enclosed seas?

Ans. A sea is connected to other seas or oceans by narrow waterways and surrounded by two or more states is called enclosed seas. The Baltic Sea, the Black Sea, the Mediterranean sea, and the Caspian sea are enclosed seas.

Q3. What factors play a major role in determining the salinity of seawater?

Ans.The salinity of the sea differs from one place to another place. Therefore, river discharge, precipitation, and evaporation are the important factors that determine the salinity of seawater.

Q4. What are the uses of oceans for humans?


Oceans are the depots of fish and minerals.

They are useful in transportation because they provide the cheapest route for trade and purposes.

They control climatic conditions.

Q5. Why is the ocean blue?

Ans. The ocean absorbs yellow, red, and orange by water rather than blue. It is due to the absorption and scattering wavelength of the light in the ocean. Therefore, the ocean turns blue when the white light from the sun meets the ocean.

When Google Serps May Undergo A Sea Change

I’m a search geek. I read through patents that provide hints and possible glimpses behind the curtains of search engines like they are novels.

I look for patents from specific inventors, like people who might keep their eyes open for news of a new Marvel movie.

Patents don’t always provide actionable insights, but they do suggest questions and possible things to look out for or understand how search engines may be working, or even to test.

I found a patent this summer which reminded me of the concept of a sea change and how search results could transform and undergo a sea change.

One of the inventors I watch out for is Trystan Upstill, at one point the Head of Core Web Ranking and Mobile Content Search at Google.

He has been involved in some of the more interesting patents and processes at Google, like one I wrote about on How Google May Rank Some Results Based on Categorical Quality.

If you read about that one, you may see some similarities to the patent I am writing about today.

He writes about things that we may never visibly notice, that sort of happen behind the scenes (or curtains), and decide upon which pages may fill the search results we see in response to a query.

A newly granted (July 2, 2023) patent from Google has his name on it as one of the inventors, and it was filed when he was still the head of Core Web Ranking at Google back in 2023.

Adjusted Search Features

The patent starts out simply enough, by telling us:

“The search system ranks the resources based on their relevance to the query and importance and provides search results that link to the identified resources, and orders the search results according to the rank.”

The results shown are responsive to a query, and the search engines look at features of a webpage that query may appear upon and other aspects of that query, and possibly other information when determining search scores for the resources that appear in SERPs.

But most patents describe a problem that they report upon, and that problem explains the need for a patent to have been written, with an invented process that might address that problem.

Sometimes a patent will also tell us about the state of the technology at the time that patent was also written. Here is the problem, and the state of the technology as described in the summary section of the patent:

“Typically the search operation implements a robust search algorithm that performs well over a wide variety of resources. However, sometimes particular features for a particular query and a particular set of resources may be quite important in determining the search scores for the resources, while for other queries the particular features may be much less important. For example, for a particular query with certain terms, the presence of those terms in the resources may have a very strong impact on the search scores for the resources; conversely, for another query with different terms, the relative importance of the resources in an authority graph may have a much stronger impact on the search scores than the presence of query terms in the resources.

However, the relative importance of particular features for particular queries and resources is often difficult, if not impossible, to predict a priori.”

What these changes to features a page is ranked upon may mean is that in response to them, sometimes Google might adjust search features and rescore resources after a while.

The process behind the patent can include:

Receiving data that indicates resources identified by a search operation that are responsive to a query and ranked according to a first-order, each resource having a corresponding search score by which the resources are ranked in responsiveness to the query relative to the other resources identified by the search operation as being responsive to the query, wherein the search operation scores each of the resources based, in part, on features of the resource and the query, selecting a set of the resources.

Determining, from the SERPs and for each of the features of the resources and the query, an impact measure that measures the impact of the feature on the ranking of the resources that belong to the set.

Re-scoring the resources for the query in the SERPs based, in part, on the impact measures and ranking the set of resources according to a second-order that is different from the first order.

Providing, to a searcher in response to the query, search results according to the second-order, each search result identifying a corresponding resource.

Search operations may be adjusted to compensate for emergent phenomena that affect resource scoring.

Those adjustments may be determined at query time so that the foundational search operation need not be adjusted, and thus foundational search operation be built on known priors.

This approach allows for the retention of the foundational search operation that performs well for most resources in a corpus given a set of known priors, but also provides flexibility to adjust the search operation on a per-query basis when particular features affect the ranking of resources in a way that departs from the expected effects.

The re-ranking of resources resulting from scoring pursuant to the adjusted search operation tends to surface more prominent resources that are more likely to satisfy a user’s informational need, thereby increasing the quality of the overall user experience.

The ultimate goal is expressed there as providing resources that are “more likely to satisfy a user’s informational need, thereby increasing the quality of the overall user experience.”

This adjusted search features patent can be found at:

Filed: May 21, 2023


“Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for receiving queries, and for each received query: receiving data indicating resources identified by a search operation as being responsive to the query, wherein the search operation scores each of the resources based, in part, on features of the resource and the query, selecting a subset of the resources, determining, from the subset of resources and for each of the features of the resources and the query, an impact measure that measures the impact of the feature on the ranking of the resources that belong to the subset, adjusting the search operation based on the respective impact measures, and initiating the search operation to re-score the resources in the subset of resources based, in part, on the adjustment and to rank the subset of resources according to a second-order that is different from the first order.”

More on Adjusted Search Features That May Change Search Engine Scores

I mentioned search engine scores that may be created according to “multiple features of the resource and the query.” These features could be related to:

Information retrieval, such as features related to recall and precision.

The relative authority of a resource in a resource graph.

The query terms.

User feedback of the resource given a query and other queries.

The patent tells us that “these features may be modeled in the search engine as parameters, and various parameter values may be selected for each parameter.”

How these search features are valued may be part of the what makes search engine scores work well. They give us an example:

“For example, with respect to a resources authority score, a parameter value may be a weight by which a feature value for the resource–the authority score–is multiplied or otherwise adjusted; with respect to resource terms and query terms,

Parameter values may include synonyms, related terms, and weights by which matches of terms and term counts are multiple or otherwise adjusted; and so on.”

So according to this patent, search could be a very complex process that looks to multiple types of scoring contributions of different types based upon a number of different types of parameters which could be related to features from web resources on the content of a query.

The search operation, once built, tends to perform well over a wide variety of search queries and documents. This could present some issues that need to be overcome, and the patent describes those for us.

It tells us that:

Some features may exhibit much more influence on the scoring of the resources than for other queries and other resources

Some features may exhibit much less influence on the scoring of the resources than for other queries and other resources

When a subject is a fairly new one on the Web (which they are referring to as an “emergent subject”), Some aspects of a score may have more impact than others:

“Furthermore, such influences may be evanescent; for example, for an emergent subject, an information retrieval score may be more influential for the first several weeks, and then, at a later time, authority scores and user feedback scores may tend to grow in influence. Thus, tuning a search operation to compensate for these features is difficult prior to their detection, if not impossible.”

So, the focus of this patent is on “when certain features exhibit greater or lesser impacts on the ranking of resources for a search operation for a query and then adjust a search operation based on the impacts.”

If you’ve ever ranked a page in a fairly new subject area, and one day the search results that it appears in all of a sudden seem to shift around and change (undergoing a sea change), the next paragraph from the patent could explain why that might happen as search results get adjusted:

“The adjusted search operation is the re-run on the identified resources to re-rank the resources in a manner that takes into account the detected impacts. In some implementations, an initial search for a query is executed, and a proper subset of the ranked resources, e.g., the top N ranked resources, is processed to determine appropriate modifications to the search operation. The search operation, adjusted by the appropriate modifications, is then re-run to re-score and re-rank the resources.”

When I read the next paragraph in the patent, I was reminded of a post that Jason Barnard wrote about ranking at Google, based upon information he had received from Gary Illyes, Webmaster Trends Analyst at Google, which he wrote about in How Google Search Ranking Works – Darwinism in Search:

“The search engine utilizes a search operation that generates search scores for the resources and ranks the resources based on search scores. The search operation quantifies the relevance of the resources to the query, and the quantification can be based on a variety of factors. Such factors include information retrieval (“IR”) scores, user feedback scores, and optionally a separate ranking of each resource relative to other resources (e.g., an authority score). The search results are ordered in a first-order according to these search scores and provided to the user device according to the first order, or, in some situations, may be re-ranked by an adjusted search operation and provided to the user device as search results’ ranked according to a second-order that is different from the first order.”

And Then There Is Reranking of Results, or Adjusted Search Features

This is part of an adjustment of results as has been described in the patent when there may be shifts in the values that results were scored upon to modify search results:

“…the re-ranking engine, for each query, processes resources identified by a search operation as being responsive to the query and ranked according to the first order, selects a proper subset of the resources, and determines, for each feature the search operation takes into account, an impact measure that measures the impact of the feature on the ranking of the resources. The re-ranking engine can then adjust the search operation based on the respective impact measures, and initiate a subsequent run of the search operation to re-score the resources based, in part, on the adjustment, resulting in the search results’.”

Search Operation Adjustment & Re-Ranking Resources

When search results are ranked, the influence of each feature involved in ranking those is calculated, and any changes to those features may be measured by their impact.

If the impact doesn’t meet a threshold, then the re-ranking engine will not rerank the search results. If it does meet that threshold, then the results will be re-ranked.

The patent provides this peek at how reranking might take place, when Google decides to use adjusted search features.

“…then the process adjusts the search operation based on the impact measures (314). A variety of adjustments can be used. For example, depending on a category of the query, the search algorithm may be adjusted in different ways. By way of one example, if a query is categorized as being a “product” seeking query, then a relevance weight parameter value related to certain commercial content, such as reviews, pricing information, etc., may be increased; conversely, if a query is categorized as being an “informational” seeking query, then the relevance weight parameter value related to certain commercial content, such as reviews, pricing information, may be decreased, while a relevance weight parameter value related to anchor text linking to the resource may be increased, etc.”

And synonyms may play a role as well:

“…if an impact measure related to synonym matching terms is high, then the feature of query expansion may be adjusted such that a more aggressive form of query expansion is used.”

Adjusted Search Features Takeaways

The article that Barnard wrote names specific types of features that may be used to rank pages, such as topicality, quality, speed, RankBrain, entities, structured data, freshness.

Those aren’t described in this patent or discussed in any detail, but they do seem like they could be features of ranked resources or queries that could influence how a page may be ranked, which are mentioned in this patent.

If you haven’t had a chance to read Barnard’s post, I would recommend it. I read it around the same time that I first saw this patent, and I highlighted the paragraph from this patent that tells us that pages may be ranked based upon a variety of factors.

While this patent doesn’t tell us the same factors that Barnard was told, the idea that multiple factors may be involved in ranking pages at Google is one worth exploring in more detail, if you can.

What this patent adds to what Barnard told us was that Google may, upon seeing changes in the impact of different ranking signals that it may have used to rank a page beyond a certain threshold, Google may adjust rankings by applying a reranking process.

So, if you see the results that you have gotten used to for a particular query that you have been following, knowing the SERP place around that query well, and who else occupies positions in that SERP place, and you may suddenly see it shift around and change.

It is possible that Google may have adjusted search features and changed those results because the impact of ranking signals for those features may have changed.

Some Sea Snakes May Not Be Colorblind After All

For annulated sea snakes, seeing the wonderful world of color wasn’t always possible. These venomous sea snakes that roam Australia and Asia’s oceans once lost their color vision, but a new study into their genomes reveals that they have potentially regained their ability to see a wider palette of colors over the last 100 million years. The findings were published July 12 in the journal Genome Biology and Evolution, published by Oxford University Press.

[Related: A guide to all the places with no snakes.]

For animals, normal color vision is mostly determined by genes called visual opsins. Multiple losses of opsin genes have occurred as tetrapods—a group including amphibians, reptiles, and mammals—have evolved. The emergence of new opsin genes is significantly more rare than losing them. A 2023 study found that some semi-aquatic snake species in the genus Helicops found in South America are the only known snakes to regain these opsin genes.

This ancestral snake species lived on the land and would later evolve into all snake species, including sea snakes. When their genes for color vision were gone, they could only perceive a very limited range of colors. However, that likely started to change as some elapid descendants began to change. Within the last 25 million years, two elapid lineages have moved from terrestrial to marine environments.

With the fully sequenced genome of the annulated snake in hand, the team in this new study from the University of Adelaide in Australia, The University of Plymouth in the United Kingdom and The Vietnamese Academy of Science and Technology looked at visual opsin genes in five ecologically distinct species of elapid snakes. Elapids are the family of about 300 venomous snakes that include mambas, cobras, and the annulated sea snake. Looking at this family more broadly offered an opportunity to investigate the molecular evolution of vision genes. 

The team found that the annulated sea snake now has four intact copies of the opsin gene SWS1. Two of these genes are sensitive to ultraviolet light that has shorter wavelengths, while the other two genes have evolved a new sensitivity to the longer wavelengths of light that dominate ocean habitats. 

“Only one [of these genes] was expected. To our knowledge, every other ~4000 snake species in the world (except a couple of Helicops species) have just one of these genes. The most interesting part is that two of these genes allow for perception of UV light, while the other two allow for the perception of blue light. This is expected to dramatically increase their sensitivity to colors which could be very useful in bright-light marine environments,” says Rosetto.

The authors believe that this sensitivity means that the snakes could have color discrimination that allows them to distinguish predators from prey, as well as potential snake mates against the more colorful background in the ocean.  

[Related: How cats and dogs see the world.]

This significantly differs from the evolution of opsins in mammals like bats, dolphins, and whales during their own ecological transitions. These mammals saw more opsin losses as they adapted to dim-light and aquatic environments.

Tired Of Minimalism, This Designer Wants To Bring Skeuomorphism Back

You could argue that Apple’s Scott Forstall-era iPhone software gave digital skeuomorphic designs a bad name, especially after skeuomorphism escalated to an obnoxious level in iOS 6 which culminated with Forstall’s departure and the Great Flattening of iOS.

A software calendar with a skeuomorphic design would typically imitate the appearance of binding on a paper desk calendar complete with faux coiled wire hinge. Or, a note-taking app might mimic the appearance of yellow post-it notes and implement faux leather stitching.

This was the golden age for skeuomorphism.

Nowadays, the software on our mobile devices and even computers is minimalistic, employing eye-candy such as translucency and layers of animated objects to keep users engaged.

Your typical skeuomorphic design: iOS ‘s Calendar app on iPad

Tired of minimalism, one designer wants to bring skeuomorphism back.

“I recently got to work on some old-school skeuomorphic interface for the calendar app Opus One,“ wrote Michael Flarup, designer, entrepreneur and keynote speaker. “I still love working on crafting experiences like this and had a lot of fun making leather, paper and metal again.”

Available on Dribble, his skeuomorphic concepts for the Opus One app veer off the path of minimalism, expectedly evoking strong reactions. As evidenced by the screenshots, you probably haven’t seen this amount of skeuomorphism on an iPhone X before.

And thanks to the phone’s OLED display with vivid colors, it works great—especially with the lighting on the side tabs really popping out and giving a Neoprene-like texture to them.

It’s easy to see skeuomorphic design pieces as dated.

Most of them are because we collectively stopped doing them. Most visual designers of that time moved on to make simpler interfaces and, like myself, found their playful-fix in game interface design, icon design and other places where you weren’t laughed out of the room for playing with gradients and lighting.

But something is changing.

Google made gradients and shadows less of a design offense with their Material Design and I’m seeing more and more tactility make it’s way into interfaces around me. Buttons have started to stand out. Whimsy has started to be a differentiating factor— not just in animation and interaction (where whimsy was banished to live under the rule of minimalism) but also in visual design. It’s been a slow march back towards bringing fun into UI design again— but I finally feel like we’re close.

He’s right that skeuomorphism has evolved from its green felt and linen days when it became one of the nastiest things you could say about a design to the modern, subtle interactions, if only as a differentiating factor. “What I am saying, and what I have always said, is that design can be anything we want it to be,” he said. “We should strive to make fun and memorable experiences that are appropriate to the context, but not arbitrarily restricted.”

Is this a great comeback for skeuomorphic designs or what?

Asked last June how he felt about his skeuomorphic designs for the iPhone and iPad software, former iOS chief Scott Forstall responded by saying the following:

If you look at the designs we did at Apple, we talked about photo illustrative designs, metaphorical designs. And those were infused into the design sense of Apple by Steve Jobs since the original Mac if not earlier. The original Mac had a desktop and folders that looked very much like the desktop on which that Mac sat.

And so we used these design philosophies. It doesn’t mean that we loved every single part of it. It doesn’t mean I loved every single part of it. There’s definitely things that I was less a fan of than others. But we built these designs that worked. And how do we know they worked? You just had to watch people use it.

Any designer could tell you that skeuomorphic design debate isn’t dying down, far from it. Let me refresh your memory with Apple’s original ad for the major iOS 7 overhaul.

It’s certainly difficult to draw a line between pure minimalism and skeuomorphism.

Just because a piece of software appears to use a flattened appearance, like iOS, doesn’t mean it’s 100% minimalistic. As a good example, those switches in the Settings app on iPhone and iPad for you to turn functions on and off–well, that’s skeuomorphism. And your desktop OS, with windows mimicking sheets of paper filling your desk that you can move around—that’s another example of the principles of skeuomorphism.

Justin Baker, lead Product Designer at chúng tôi summed it up nicely:

Modern skeuomorphism, therefore, is the bridge at the intersection of digital and industrial design. It is about facilitating non-traditional device interaction without sacrificing usability. It is about enriching and enlivening real world objects in the context of our human physiology.

Are you feeling nostalgic for skeuomorphic designs? Do you miss skeuomorphism in iOS?

Fix: Windows Firewall Has Blocked Some Features Of This App

FIX: Windows Firewall has blocked some features of this app




Some users have stated on forums that the Windows Firewall has blocked some features of this app alert keeps popping up on regular basis.

That notification window pops up every time they open specific software (which usually requires a net connection), such as Chrome, iTunes, Spotify, Kodi, Edge, etc.

It is not an error message, but some users need to get rid of the firewall alert that pops up with regularity. These are a few resolutions that might fix the Windows Firewall has blocked some features error.

How do I stop Windows Firewall from blocking app features? 1. Scan for Malware

The Windows Firewall has blocked some features error might be due to malware that resets firewall settings. As such, it might be worth running a malware scan.

You can find many effective antivirus programs that provide strong guarding on your PC, keeping malware and other cyber threats away round-the-clock.

Using proper software, you can benefit from powerful anti-malware tools that offer comprehensive scan and high detection rates of intrusive malware.

In addition, it’s worth mentioning that antivirus software will protect your system completely, covering browsing security or gaming modes. Thus, we recommend you choose the best antivirus software today.

2. Open the Windows Firewall Troubleshooter

First, check out the Windows Firewall Troubleshooter for Windows 10, 8.1, 8 and 7. That’s a troubleshooter which can fix numerous WF errors.

3. Turn Off the Windows Firewall

Select both the Turn off Windows Defender Firewall options, and press the OK button.

Add one of the third-party firewall alternatives included in this article to Windows.

Expert tip:

You don’t necessarily need the Windows Defender Firewall on as you can replace it with a third-party alternative. This is how you can switch off the Windows Defender Firewall.

4. Allow the Software Through the Firewall

Press Cortana’s Type here to search taskbar button.

Enter the keyword ‘firewall’ in the search box.

Then select to open Allow an app through Windows Firewall.

Press the Change settings button to adjust the options.

The Windows Firewall has blocked some features of this app alert window requests that you permit an app through the firewall.

However, you might still need to let an app through the firewall via the Windows Defender Firewall settings to ensure the alert doesn’t pop up for particular software.

5. Disable Network Adapters

Enter ‘devmgmt.msc’ in Run and press the Return key to open the window below.

Select Network adapters to expand that device category as below.

If you prefer to keep the VPN software, try disabling the VPN’s network adapter via Device Manager. Some users have confirmed they’ve fixed the issue by disabling a network adapter.

6. Uninstall VPN software and extensions

The Windows Firewall has blocked some features error can also be due to VPN client software and extensions.
