Suggested January 2024 9 Hidden Customization Settings To Get The Most Out Of Your Mac

There are many features in macOS that are unknown to many. In some cases, a macOS user can go years before making a new discovery. That is, until you have read some of the best macOS hidden customization settings to help you get more out of your Mac.

1. Cleaning Up System Preferences

System Preferences on the Mac is a one-stop shop for all of your main settings. However, for all of the items you need on this menu, there are plenty you don’t. Use this handy trick to clean up the menu and only leave the settings you want.

2. Find the Emojis

Did you know the Mac has its own emoji keyboard? They are all available right from your Mac keyboard, and you probably never knew they were there. Accessing the emojis is as easy as hitting Control + Command + Space. Once you hit that combination, the emoji picker automatically opens. You can use emojis in a variety of applications, especially Safari, Mail, Calendar, Reminders, Notes, and iMessage.

3. Rename Multiple Files at Once

This is definitely one of the handier tricks, especially for managing photos. To do this, go into Finder and find a bunch of photos, documents or whatever file type you prefer.

4. Automatically Launch Programs

One of the easiest tips you can discover on a Mac is to start applications at launch.

To get started:

Head to System Preferences and choose “Users & Groups.”

On the right side of the window, you’ll have an option for “Login Items.”

Under that heading, you can add or remove applications by using the plus or minus buttons.

A word of warning for this tip as well: don’t initiate too many programs at launch, or you might slow your computer’s startup time. Adding Spotify/Apple Music, a browser, Twitter and smaller applications is perfectly fine.

5. Combine Open App Windows to Tabs

Instead of keeping multiple application windows open, combine them with tabs.

6. Spotlight Does Math

macOS comes with a calculator, but sometimes you just want to do a quick math calculation. Did you know that Spotlight can do math or currency conversion?

To convert currency, open Spotlight again and type in the amount you wish to convert. For example, if you put $100 into the search bar, it will return currency conversions in Japanese yen, Swiss francs, Canadian dollars, British pounds and Euros.

7. Create Keyboard Shortcuts

Keyboard shortcuts are hardly new for most computer users, but did you know Apple allows you to create your own?

8. Stop Autoplaying Content

Open Safari and go to Preferences at the top of the menu bar.

Head to the “Websites” tab.

Find the option labeled “Auto-Play” and open the drop-down menu to choose to stop audio and video from playing automatically. You can also block videos entirely that have sound enabled.

9. Muting Siri

Everyone knows the distinct sound of Siri’s responses, but that doesn’t mean they are required. Instead, opt for a silent Siri response with this macOS tweak.

The above-mentioned tips are a few of the hidden customization settings in Mac, with more features like changing folder icons, managing multiple app windows, etc. not included. These showcased the power of macOS and all of the easy ways you can adapt it to your own use. What’s your favorite hidden Mac setting?

How To Get Water Out Of Your Iphone

Our smartphones go everywhere with us, and lots of the places we go are wet! If you have water in your iPhone, you can do a few things to rectify the situation.

Liquid exposure isn’t the immediate death sentence it used to be, but it can still wreck your phone. Here’s what to do when things get splashy.

Table of Contents

Water Resistant Doesn’t Mean Waterproof

Before we get into how to deal with water in your iPhone, let’s clarify what your iPhone is designed for regarding water resistance. The first iPhone to get an IP (Ingress Protection) rating was the iPhone 7. That doesn’t mean that older iPhones didn’t have some measure of water resistance; it’s just that they were not tested and certified. Apple makes no promises about models older than the iPhone 7.

Some manufacturers add additional resistances under the rating, the time duration can be much longer, and depths are generally up to 9.8ft. If your iPhone has an IP68 rating, look up the specific resistance specifications for that model.

The water resistance rating applies to a new iPhone in perfect condition. Wear and tear on the device can compromise its IP rating. If your phone’s been dropped a few times, bent a little in your pocket, and has small cracks anywhere, that may give water a way inside.

Not All Liquids Are Equal

Apart from your phone being water resistant rather than waterproof, the type of “water” also matters. When the certification tests are done, it’s with water that’s quite pure. That’s not the case with rain water, swimming pool water, salt water, or that puddle of mud your phone falls into when you get out of your car. Plus, some liquids are not water, such as cleaning agents or other chemicals, that can quickly cause corrosion.

These real-world liquids your iPhone might encounter can compromise the water seals in your phone when pure water would not.

Water In the Lightning Port

A typical example of water in your iPhone happens when you get an error message that tells you water has been detected in the Lightning port. This disables charging to prevent a short circuit through the Lightning connector that can damage your phone’s internal components.

You can follow our complete guide for more details, but the short version is that you shake out any excess liquid in the port. Then put the phone upright somewhere with low humidity and good airflow at room temperature. Wait a few hours for the port to dry naturally, then try connecting the charger again. Do not attempt to dry the port by inserting anything into it.

What to Do With a Wet iPhone

If your iPhone has been splashed with water but hasn’t been immersed in it, it will probably be okay unless its water seals have been compromised.

If you have a water-resistant iPhone, you may want to rinse it gently with clean tap water or, ideally, distilled water free from impurities. However, since most people don’t keep bottles of distilled water around, tap water is your next best choice. This helps remove corrosive liquids or other impurities, such as salt or minerals.

If you have an iPhone that’s not water resistant, a damp cloth is a good alternative, or perhaps even preferred for a water-resistant model if you don’t want to take any chances.

Once you are satisfied that your iPhone is free from pollutants, use a soft, absorbent, dry, lint-free cloth to try it as well as you can. A paper towel can also work, but some coarse ones could scratch your phone. Do not try to force the cloth into the charging port; see the above section about Lightning port liquid for more details.

You may be wondering if you should turn off your iPhone. The idea is that turning off the phone prevents short circuits if the liquid comes in contact with a conductive trace. If the liquid has intruded into the phone deeply enough to cause a short circuit, turning it off won’t make much difference.

You should not open the SIM tray until the phone is completely dry! Once confident, open the SIM tray to check for any liquid inside. You’ll also find the liquid damage indicator, which we’ll explain below under “Checking for Water Damage.”

What to Do With an Immersed iPhone

If your iPhone wasn’t merely splashed but went for an impromptu swim, there are some differences in how you should handle things.

First, get the phone out of the water as quickly as possible, especially if the water is deep. The time the phone can resist water ingress drops rapidly in deep water.

Once you have retrieved your phone from the depths, shake it firmly (but carefully) to expel the excess liquid. Rinse it as described above if the liquid it fell into has impurities. From there, proceed as you would with a splashed phone.

The Uncooked Rice Myth

With a phone exposed to water, a key goal is to get the water out. However, there are plenty of myths about how to do this, and the most infamous one might be putting your phone in a bowl of uncooked rice.

The thing is, it just doesn’t work, and the dust and starch from dry rice can damage components. Plain old air is much better at removing water from your phone. It may take longer than usual if you live somewhere with high atmospheric humidity, but air will remove all the water eventually, except if there’s water somewhere airtight. However, if it was airtight, it was probably watertight as well!

You might have some luck putting your phone in a sealed container and silica gel packets, which capture water droplets from the air and reduce the humidity, but it’s not a magic bullet.

You should also avoid using heat sources such as a hair dryer to speed up the process. This can damage the phone in several ways. It can melt the adhesive that holds the phone together, cause the battery to overheat and fail, or damage components that are not designed to withstand those temperatures. It’s best to be patient.

Checking for Water Damage

From the iPhone 7 and later, iPhones include an LCI or Liquid Contact Indicator. This is a little strip or dot of material that changes color permanently when it comes in contact with liquid. There may be several of these inside a phone; this is how Apple and other phone makers can tell if water has made it inside a phone.

You can see one of these indicators if you remove the SIM card of your iPhone, and if it hasn’t turned red, it means water did not make it in through the SIM tray, at least. This is one of the main reasons we recommend ensuring the phone is dry before popping out the SIM!

Check out Apple’s LCI location page to see which iPhone models have an LCI and where to find them.

Eject Water From an iPhone Speaker

The speaker ports in an iPhone with a water resistance rating won’t be ruined by water, but it can lead to muffled or quiet sound. Any water in the speaker ports will eventually go away through regular air drying via the speaker grills; however, you can theoretically eject excess water from the speaker port using sound pressure. The idea probably comes from the official sonic water ejection feature found in the Apple Watch and is essentially a DIY copy of it.

Several YouTube videos claim to provide a sound that efficiently ejects water from iPhone speakers, and there’s no harm in trying one to see if it works for you. There may be apps on the App Store that promise to do the same thing but save your money and just play a YouTube video instead.

When to Take Your Phone In

A water-damaged iPhone (or Android phone!) is one of the hardest things to fix, and if water has penetrated the interior of your iPhone, it will most likely need a replacement rather than a repair. If your phone is behaving strangely after being exposed to water, if the SIM LCI has been triggered, if the buttons don’t work or register phantom presses, or if the phone won’t turn on at all, it’s time for professional help.

The standard Apple warranty won’t cover accidental water damage. However, if your phone is still in good condition with no reason that the water seals should be compromised, you might have a case with Apple Support that the damage happened due to a factory fault.

Ultimately, it’s better to pay for accidental damage insurance covering water damage since we live in a wet world, and the chances that your iPhone will be splashed or dunked at some point are likely.

10 Tips To Get Most Out Of Safari In Ios 13 And Ipados 13

Best Safari Tips to Get the Best Browsing Experience in iOS 13 and iPadOS 13

Even if you have taken a close look at Safari, chances are you might have missed quite a few new additions. It’s because the revamped web browser has got many new features under the hood. Whereas the headlining additions have got the most attention, the ones that are slightly under the wraps haven’t yet got any substantial coverage. And, I bet you will find them equally appreciable. With that said, let’s get started!

1. Customize the Download Manager

2. Request Desktop Website

Another feature that has enhanced web browsing in Safari is the ability to request a desktop website with ease. Though Apple’s web browser already had the option to switch to the desktop version of a site, switching back to the mobile version was a huge pain in the back due to the lack of a straightforward method. But those days are gone for the better. With iOS 13, you can quickly switch between the desktop and mobile versions of a website on your iPhone. To request the desktop version of a website in Safari on your iPhone, simply tap on the text button at the top left of the screen in the search bar and choose Request Desktop Website.

3. Send Content As PDF or a Web Archive

While browsing the web, I make it a point to save all of my favorite stories to catch them later with peace. So, it’s my favorite feature and I’m sure a lot of users are going to love it as well. In the Share Sheet, there is a new option to share an entire web page as a web archive or PDF. To do so, simply tap on the Share button and then select Options. Then, you have four options: Automatic, PDF, Reader PDF, and Web Archive. Select your most preferred option and then hit Done at the top right to finish.

4. Automatically Close All Tabs

5. Choose What Size of Photo to Upload

This one, kind of, kills two birds with one stone! Well, if you didn’t get a good hang of the idiom, let me tell you that Safari now lets you choose what size of a photo to upload. It can not only speed up the uploading process, especially when you are dealing with high-resolution images, but also save plenty of mobile data on your iPhone and iPad. So, save this hack to prevent your limited bandwidth from ending well before the deadline.

1. Simply choose the option to upload an image on a website in Safari and then select Photo Library.

2. Now, select the images you want to upload. After that, you should see the actual size of your images. And below the actual size, there will be an option to choose image size. Tap on it and then choose the preferred image size. You have multiple options like Large, Medium, Small, or Actual Size.

3. Next, return to your photo library and tap on Done in the top-right corner of the screen to start uploading the image.

6. Customize Your Favorite Sites

7. Customize Website Settings

Wouldn’t it be better if you could customize your favorite websites so that every time you visit them, they would look in line with your taste? Well, with iOS 13 and iPadOS 13, you can fine-tune website settings. Whether you are an avid reader or someone who likes exploring the web, you would find it very handy. To customize website settings in Safari, simply tap on the tiny text button at the top left the search bar and then choose Website Settings in the menu. After that, fine-tune all the options depending on your needs. For instance, you can use reader mode automatically on the site, allow it to access the camera and microphone of your device. Once you have customized everything, tap on Done to confirm the changes.

8. Delete Frequently Visited Sites

9. Access Open Tabs from Search

Well, this one might sound too little a feature to find a mention in this notable roundup. But let me tell you that it can play a good role in speeding up your web browsing experience on your iPhone or iPad. When you type the address of a website in the smart search, the web browser automatically directs you to the related open tab; instead of opening a new tab. Thus, you don’t need to open unnecessary tabs in the web browser.

10. Save All of Your Open Tabs As Bookmarks Bonus: Make the Most of All-New iPadOS Safari Keyboard Shortcuts

If you want to enhance your productivity, never miss out on the keyboard shortcuts as they can save plenty of time. And if you like to use shortcuts to get your work done faster, you would be glad to know that Apple has introduced around 30 iPadOS Safari keyboard shortcuts that are quite handy. Moreover, the work with not only Apple’s Smart Keyboard but also any third-party Bluetooth keyboards.

How To Get Water Out Of Charging Port?

Did you accidentally spill water on your phone or drop it in water? Happens to a lot of us. These days, water-resistant devices are more popular than ever, but they’re still not immune to water damage. Especially if the charging port is moist, any device can malfunction. 

Even if you’re unaware of how water got into your charging port, most smartphones give you a liquid-detection alert. Luckily, there are some easy ways to get your phone or tablet dry as quickly as possible. So, let’s quickly jump into how to get water out of the charging port on all devices. 

Charging your phone when the port is still wet can lead to unwanted consequences. Hardware components, like the pins and the cables, can get damaged. As a result, your charging cable or the port may stop working.

Additionally, you might also get electric shocks while trying to charge your phone.

However, if you accidentally charged your phone and are worried, you can check the IP rating of your phone.

Ingress Protection denotes how effective your phone is in terms of water resistance and dust particles.

There are two numbers in the rating, for instance, IP68. The first number represents the level of protection against solid particles, and the second number refers to liquid. The more the numbers, the better the protection.

So, the ideal IP rating is IP68, as it refers to full protection against both dust particles and liquid. If your phone is either iPhone 12 or Samsung Galaxy S21, you can rest assured as both phones have IP68. Nevertheless, such phones cannot continue functioning properly while being immersed in water for an average of more than 30 minutes.

If you just dropped your phone in water or somehow got the port wet, firstly don’t panic. There are ways you can save your phone from serious damage quickly. Carefully follow these steps: 

Important Note: Always wear gloves while dealing with issues around the charging ports, cables, and plugs. Do not use any sharp objects to apply pressure into the port. This is to ensure you don’t get any electric shocks or accidentally damage the charging port.

Firstly, shut down your phone and give it a gentle tap to get the excess water out. We can now proceed to further solutions.

First, you’ll need to get rid of the moisture. You can do this by taking a tiny piece of soft cotton cloth. Now, gently try to clean the charging port by rubbing the cloth inwards.

Then, you can let your phone dry on its own for up to half an hour or more. Be sure to not apply a lot of pressure as it can push the water inside the port. 

One most effective method is to let the phone dry naturally. Usually, the water inside the port will evaporate in a few hours. While you’re doing this, make sure you’re keeping the phone upright. Also, it’s best to place your phone in an area where it’s well-ventilated. 

If your phone is not charging with a cable despite using the methods above, try using a wireless charger. However, we recommend making sure the phone and the wireless charger are dry before charging. 

If the above solutions didn’t work and you believe the charging port is damaged, you can try contacting customer care service. For Samsung users, you can contact their Support page, or you may even visit their walk-in service center. If you have an iPhone, you can contact the Apple Support page. 

You may even take your phone to a local repair center if your phone is not turning on after trying the fixes above. 

It’s natural to panic and take quick measures when trying to save your phone from water damage. But not all tricks work the same. Let’s look at some of the don’ts while trying to dry your phone.

It’s common to believe it’s a good idea to let your phone evaporate in the sun. However, prolonged sun exposure can cause permanent damage to your phone. Your phone’s battery can overheat, and the hardware components, like the miniature circuit board, can get damaged. Additionally, your phone’s screen might also crack due to the high temperature. 

Placing your phone inside dry rice overnight is an old method to dry your phone. However, it doesn’t always work properly. Tiny dirt particles in the rice or even the rice grains can get inside the charging port. Instead, you can use other methods above or place silica gel sachets near the charging port. 

Using cotton swabs to get rid of excess moisture from your phone may seem ideal, but it’s not. Rubbing the swab in the port can get the tiny cotton dust particles inside. The swab may also push the water further inside. 

If you use a paper towel inside a wet charging port, the towel will also get wet, and it can get inside the port. It’ll be difficult to take out wet tissue particles from the port. So, it’s best not to use this method. 

Using a vacuum hose might get some water out, but the air pressure can interfere with the internal components inside your phone. Additionally, a vacuum hose can’t get rid of other liquid dirt from the port. 

A hairdryer blows the air directly inside the charging port of your phone. This will push the water further inside, which can cause more harm than good. You can instead just use it diagonally at the lowest speed and in a cold air setting. 

If you’re unsure what to do, you might feel like letting your phone sit for extended periods of time, like a few days. However, this can lead to a problem called Corrosion. It is the slow damage to electronic components due to environmental changes. It might take up to a few weeks to notice symptoms of corrosion on your phone. 

Shaking the phone will not get rid of the moisture. Instead, it might push the water further inside the charging port. This can cause more damage, and it might take more time to dry your phone. 

Any sharp objects, like a toothpick, can cause more damage inside the charging port. So, it’s best not to use toothpicks even if you wrap cotton around them. 

As mentioned above, if you notice symptoms of corrosion on your phone, it signifies that it’s too late to apply simple solutions. Since corrosion causes permanent damage, it might be difficult or costly to fix your phone. 

If you’re no longer getting moisture or liquid detection alerts on your phone, you can figure that your phone is completely dry. Additionally, if you’re not noticing any minor glitches, your phone is completely dry. 

If you can confirm that your phone is completely dry, but you are still getting liquid detection alerts, here’s how you can fix it. 

You can also simply turn off the moisture notification from your settings. Here’s what you’ll need to do: 

Power Cycling is like a hard reset option. It’s a method of shutting down and restarting the phone’s hardware. You can do this by simply switching off your phone, waiting at least one minute, and then powering it on. 

You can always fix minor bugs, like false alerts on your phone, by updating the OS. Simply check and install any available software updates. 

There’s a chance you might get false alerts if there’s water in your charging cable or if it’s damaged. So, just switching to another charging cable might prevent your phone from giving you such alerts. 

If you’re still getting moisture alerts even after power cycling, you can restart your phone on Safe Mode. 

On Android

Shut down your phone and let it be for a few seconds. 

Hold the power button again for 2-3 seconds. You’ll get a pop-up option to confirm rebooting in Safe Mode. 

Tap on OK. 

On iPhone

Turn off your iPhone. 

Turn on your iPhone and when it’s lighting up, hold down the Volume Down button until you see the Apple logo. 

When the phone is booted, it goes in Safe mode. 

If there are still dirt particles or rust inside the port, you might get false moisture alerts. You can use flashlight to look into the port.

If most solutions aren’t working, you can try performing a full factory reset on your phone. However, please note that this will clear all your data. So, it’s best to make sure you have backed up all your data. Since this step can be risky, please try this method at the end. 

On Android

Please note that the settings may differ depending on your current Android version. 

On iPhone 

If the above solutions are not working, you can try replacing the charging port. You can do this at a local electronics repair shop. 

If your phone is now dry and working fine but there’s no sound, there might be a problem with the speakers. Check if there’s water in the speaker area. You might also not hear any sound if it’s connected to another device via Bluetooth. 

You can also check the volume level and whether it’s in Do Not Disturb mode. Alternatively, try rebooting your phone. If nothing is working, you can get your phone repaired at a local electronics shop. 

Firstly, turn off your phone and take it indoors where it’s warm. Then, with a clean, soft towel, get rid of the excess snow. You can then try the methods above to remove moisture and dry your phone. Alternatively, you can also take it to a local electronics shop. 

If none of the solutions are working and your phone doesn’t seem to turn on at all, it’s best to call for help. A dead phone after such accidents signifies that there’s been serious damage. You can take your phone to any local repair shop or contact the respective Support page of your phone’s brand. 

Mapping The Hidden Universe In Your Kitchen

Invisible World

On a recent morning, Noah Fierer, a professor of ecology and evolutionary biology at the University of Colorado, Boulder, found himself standing 1,000 feet above the farmland of eastern Colorado. He was perched near the pinnacle of the Boulder Atmospheric Observatory, a cellphone-tower-like spire built in 1977 to conduct climate and weather research. To reach the top, Fierer and his colleague Joanne Emerson had taken a five-minute ride in the tower’s cramped elevator to an even more cramped catwalk 90 stories up. Dressed in hard hats and safety harnesses, the two leaned over to check a small device strapped to a latticework platform. The machine, which they’d installed several months earlier, sucked in air every night, filtered it, and stored the contents for collection every two weeks. It was basically a vacuum cleaner but instead of hoovering up dirt, it captured microbes.

Microorganisms surround us. In the relatively desolate atmosphere at 1,000 feet, every cubic meter of air contains about a thousand microbes. Closer to the ground, that number skyrockets to 100,000, and on every square centimeter of human skin, it jumps to 10 million. A teaspoon of dirt contains 50 billion microbes, more than seven times the number of people on Earth. Yet despite such abundance, scientists know little about the microbial ecosystem. We understand less about the bugs in our home, for example, than the animals in the deepest ocean trenches. We know even less about their impact on us. How do microbes shape our daily lives—and how do we shape theirs? Do they trigger asthma and allergies—or help prevent them? It’s as if we’re living in an invisible world, and like the Victorian naturalists before him, Fierer is charting it.

One of the country’s foremost microbial ecologists, Fierer collects and classifies microorganisms such as bacteria, archaea, fungi, and viruses. “I’m a natural historian of cooties,” he says. Until a few years ago, microbial ecology was a relatively staid field. Because of the tiny size of the organisms involved and the inability to grow many of them in petri dishes, Fierer says, most microbiome studies were akin to surveying the biodiversity of the Amazonian rainforest and coming back with five species. Then came DNA sequencing. Fierer and others can now classify thousands of species quickly and easily and determine their functions. “It’s fair to say we are entering a golden age of microbial ecology,” he says.

In the past five years, Fierer has explored the microbial diversity of such environments as public restrooms, armpits, and caterpillar stomachs. Sometimes his findings shed light on the greater realm of microorganisms. At the Boulder Atmospheric Observatory tower, he’s helping Emerson determine what kinds of creatures can survive in the air currents that blow in from California and beyond. Other times, his discoveries tell us about ourselves and how we unknowingly shape the microbial world. He’s proved, for example, that people leave behind unique microbial fingerprints on surfaces like computer keyboards long after they’ve touched them, a fact that made it into a recent CSI: Crime Scene Investigation episode. (No one has used the technique in an actual investigation yet.)

Lately, Fierer has turned his attention to one of the richest and least understood microbial environments: the American household. In 2011, he joined the Wild Life of Our Homes project, which was started by Rob Dunn, a biologist at North Carolina State University (and Fierer’s co-author on studies that explored beetle bacteria and the organisms living in our belly buttons). The project aims to map the microbial biodiversity of homes across the U.S. “We really didn’t know what to expect,” Fierer says. As he and Dunn often point out in their research, there are more kinds of microbes in a typical home than there are species of birds on Earth. “It should be shocking to people that we live with thousands of species, some of which make us sick and some of which don’t,” Dunn says. “We have no idea what determines which ones live in your house, and for the most part, we have no idea which ones are beneficial or detrimental.”

Noah Fierer

In Fierer’s Boulder lab, researchers extracted the microbial DNA from the swabs using chemical solutions and centrifuges; then they chemically amplified and sequenced specific marker genes that could help identify species and their functions. In a matter of months, the team had compiled the largest data set on microbial ecology ever assembled. It contained hundreds of millions of DNA sequences and started yielding discoveries almost immediately. For example, researchers found about 3,500 bacterial species on interior door trims, meaning there are about 3,500 kinds of bacteria floating about in the average house—500 more than the study found deposited on exterior door trims.

fungal-community types collected on doorsills, one predominately along the East Coast and in the Pacific Northwest, and the other prevailing everywhere else. “As soon as we saw it, we said, ‘Holy crap, there is some structure here,’” Fierer says. What causes the different microbial clouds? Fierer thinks they could be linked to geographic patterns, including precipitation, soil pH levels, and forest cover. But only more research can say for sure.

There are more species of microbes in a typical home than there are species of birds on Earth.

Fierer could also see forensic applications for his work. “We may be able to demonstrate that we can use microbes found inside or outside homes to pinpoint where that home is located,” he says. “It could even be used to determine where a criminal had been by looking at the microbes deposited on his or her clothes or deposited on surfaces in a car.”

Data analysis on Wild Life of Our Homes continues, as do efforts to develop digital interactive “report cards” that will allow the 1,400 volunteers to learn about the abundance and likely environmental sources of the various microbes that live on their pillowcases. In the meantime, Fierer is developing new projects. He’d like to investigate the links between skin microbes and body odor, and he champions the idea of protecting endangered microorganisms. “There’s lots of literature on plant and animal conservation, but what’s often left out is conserving microbes,” he says.

As Fierer lists all the projects on his bucket list, it’s hard not to picture a very different world from the one we know, one in which every surface has seething bacterial colonies, fungal deposits, and viral hoards. Yes, Fierer explains, we’re all steeping in microbial soup—for better and worse. “Thankfully,” he says, “I am not a hypochondriac.”

What’s living with you?

Katie Peek

One morning about a year and a half ago, at my home in Brooklyn, New York, I woke up the usual way: My dog leapt into bed and plopped his face on my pillow. That day, I wondered what came with him. Did living with an animal influence my apartment’s microbial composition? To answer that question, I signed up for the Wild Life of Our Homes project, run by Rob Dunn at North Carolina State. Volunteers swab prescribed locations in their living spaces to collect microbial DNA, which is then sequenced to reveal which species appear where. Here’s how I compare with 18 other people in the U.S. —Brooke Borel

A lot of us were taken aback when we heard there is something better than Jupyter Notebook. Since many of us gave our hands to Jupyter Notebook to progress in our data science journey, there was not a chance to not check the ever-better- JupyterLab.

Trust me it was love at first sight for me and I am pretty sure you will or would have also enjoyed your transition to JupyterLab to perform your data science tasks.

The new year for people using JupyterLab started with its latest version- JupyterLab 3.0. In this article, I will walk you through all the updates and changes that you can see in JupyterLab 3.0

We recommend you go through this article before proceeding-

How to install JupyterLab 3.0

If you already use JupyterLab then just use the following commands to upgrade your JupyterLab-

With pip: pip install --upgrade jupyterlab With conda: conda update jupyterlab

If you’re new then use the following commands to install JupyterLab-

With pip: pip install jupyterlab==3

But before this, you need to have pip installed on your system.

With conda:

conda install -c conda-forge jupyterlab=3

same with this, you need to have Anaconda/Miniconda installed on your system before running this command.

Changes/Improvements in Jupyter Lab 3.0 1- Debugger

JupyterLab 3.0 now comes with a front-end debugger by default. This means that notebooks, code consoles, and files can now be debugged from JupyterLab directly!

In order to use this debugger, you’ll need a kernel that supports debugging. For example, for python, we have xeus-python, commonly known as xpython. As of now, it is the only Python kernel that supports debugging and is compatible with JupyterLab. You need to install it first. Follow the following commands for installation of xeus-python-

With Conda:

The safest usage is to create an environment named jupyterlab-debugger with your miniconda installation-

conda create -n jupyterlab-debugger -c conda-forge




xeus-python conda activate jupyterlab-debugger

After this installation, you can just select this kernel from the launcher

or you can switch to the xpython kernel using the kernel selection dialog:

And then you’re all set to debug your code-

2- Table of contents 3- Changes in the Interface

There have been several changes in the user-side interface. The property inspector moved to the right sidebar now-

The command palette now comes floating on the center of the top of the window. This enables users to quickly invoke a command while keeping the sidebar closed or switching sidebar panels. You can access the command palette using the View menu or directly using the shortcut Ctrl+Shift+C.

The file browser now has a filter input which filters the list of files using the same fuzzy matching as the command palette-

And if we talk about Simple Interface mode then it has been extensively updated for a more targeted, documented-oriented feel. There is a toggle on the command prompt to switch to the Simple Interface mode,

or you can select Single Interface mode from the View menu, or you can just directly press Ctrl+Shift+D-

4- Multiple languages support

Yes, now you can change your interface and view contents in your language. For this, you will need to install a language pack. And you can get the list of available packs from here. Currently, only the Chinese language pack is available and its code is zh-CN.  So to install this pack use the following command-

With pip: pip install jupyterlab-language-pack-zh-CN

With conda: conda install -c conda-forge jupyterlab-language-pack-zh-CN

In order to install these language packs, only the language code gets changed and the rest of the command remains the same. Once you’ve installed the language pack all you need to do now is to change the interface.

Go to:

A confirmation pop-up will appear and once you will accept that and refresh your page, you’ll see everything on the screen in your selected language(Chinese in this case).

5- Another method to install extensions

JupyterLab is designed as an extensible environment. JupyterLab extensions can customize or enhance any part of JupyterLab. Earlier the Extension Manager in JupyterLab and the jupyter labextension install command can install source extension packages from npm. Installing a source extension requires chúng tôi and a JupyterLab rebuild to activate.

This method is still available if you wish to do it this way but now there’s another and easier method available which is using Python pip and conda packages.

One of the examples of extension is Debugger, which you saw earlier in this article. Another simple example of a Jupyter Lab extension is a Python file. In order to install this extension use the following command-

With pip-

pip install jupyterlab-python-file

With conda-

conda install -c conda-forge jupyterlab-python-file

As simple as that! and after successfully running this command you’ll see that the launcher now has an option of python file in it-
