What is mdworker & mds?

Mdworker is a short form of metadata server worker which indexes your files to enhance the search process.  While Mds stands for the server of metadata which manages indexes to provide fast search results. These processors are part of  Spotlight, a search tool for Mac.

Why Do mds and mdworker Consume So Many resources?

Note: The process could take hours, depending on your processor speed and hard drive. Well, Spotlight is not supposed to use excessive resources, especially when you are working on something that is CPU-intensive or consumes battery. However, it takes up all the resources needed, as and when your Mac is idle.

However, if these processes are taking a lot of time and are hogging CPU resources. then the index might be corrupted and you must rebuild Spotlight Index. For that, you can either follow the manual steps below or you can use third-party tools (mentioned one of the best tools in the second section)

Re-indexing Spotlight Manually

To do so, let’s follow the steps:

First, make sure that  mds and mdworker are the culprits

1.  Checking Activity Monitor

Go to Applications and launch Activity Monitor.

If mdworker and mds are at the top of the list, it means Spotlight has run into indexing problems.

Now, you can fix this by rebuilding Spotlight’s index.

2.  Rebuilding Spotlight’s database in Terminal

Go to Application, launch Utilities, and go to Terminal.

Type “Return:sudo mdutil –E/” string.

This command will help in re-indexing the Mac.

3.  Steps to take if mdworker quits

If throughout the process, you receive an error message that mdworker quit unexpectedly…it is happening because Spotlight tried to index more than its handling power.

To fix this, try to exclude external drives (if connected) and check if this helps.

Now, select Spotlight and then go to Privacy.

Now, drag external files from the Finder to the Privacy.

It will help to fix the slow processes of your Mac.

Re-Indexing Spotlight Via Third-Party Tool:

If you don’t want to get into the hassle of following these steps, you must use a third-party tool like CleanMyMacX

CleanMyMac X is an easy tool for fixing Spotlight and other issues related to indexing on your Mac. It is a famous Mac Maintenance software.

What Is Fleet On Twitter?

Twitter is the place where we go to find out what’s happening in the world and join in on the conversation. But, by default, the Twitter space is public and everything you tweet will stay forever, going down in the annals of time for the rest of existence.

Sure, one could always protect one’s tweets with a private account or delete tweets from their timeline one by one. But that is a hassle that not everyone is willing to undertake. So, other than securing your tweets with a lock, what other way is there to share your thoughts and opinions with the world without having your tweets remain in your feed forever?

Enter Fleets. What are they and how can you start using them? Here’s all you need to know.

What are fleets?

In November 2023, Twitter rolled out a new feature that would let users post content that would disappear after 24 hours – Fleets. This will effectively enable users to share their momentary, fleeting thoughts with their followers without having to fear the tweets sticking around till the end of time. 

When people get the freedom from being judged for possible momentary lapses of thought and judgment, they tend to be more active in sharing what they actually think and feel. Besides, you won’t have to keep your thoughts saved (and forgotten) as drafts anymore fearing that they aren’t all that important for a full-blown tweet.  

The feature is not unlike the Stories feature of Instagram, Facebook, and Snapchat, and it’s been a long time coming to Twitter. Now that it’s here, let’s see how you can use fleets on Twitter.

How to use Fleets on Twitter: Beginner’s Guide

Using fleets is quite straightforward. You can create, delete, and watch fleets of others whom you follow, reply, and even mute their accounts. Here’s how you can do all this. 

Do note that, currently, fleets only work on the Twitter mobile app.

Creating a fleet

Open the Twitter app. Make sure that you are on the home timeline. For this, tap on the Home icon at the bottom left corner. 

You are now in creation mode. At the bottom, you can select between four different options – Text (to share a fleeting thought), Gallery (add pictures from your phone’s gallery), Capture (to snap a photo from your phone’s camera), and Video (record a video). 

Once you’ve added content for a fleet, you can pinch the photo to resize it, tap on the circle at the bottom left corner to change the background color (1), and tap on ‘Aa’ to add some text (2).

On top of that, if you have a photo as your fleet content, you can even add a description for it. This you can do by tapping on ALT at the bottom right corner… 

… and filling in the description at the bottom.

Once you’re done, tap on Done at the top right corner. 

This feature is only available for photos. Videos can’t have descriptions added to them on fleets. 

You can even keep people from reacting to your fleets and sending you DMs. To do this, tap on the three vertical dots at the top. 

Toggle Off reactions and replies.

Once you’re satisfied with your fleet content, tap on Fleet at the top right corner.

And that’s it. Your first fleet is out there for the next 24 hours. It will appear at the top of your Home screen. 

You can add more such fleets by tapping on the Add button next to it. 

You can even share someone’s tweet (or your own) as Fleets. To do so, tap on the share icon at the bottom of the tweet. 

Then tap Share in a Fleet.

Edit however you want – add text or change background color – and then tap on Fleet in the top right corner.

Tap on the three vertical dots at the top right corner. 

Tap on Delete Fleet.

Your fleet will be removed.  

Watching a fleet

Once the fleet is over, the next ones in the list will play automatically. 

If you want to see who viewed your own fleet, simply open your Fleet and tap on Seen By at the bottom. 

Replying to a fleet

Mute an account

If there’s a user whose fleets keep popping every now and then that you’d rather not see, there’s a way to avoid these as well. 

Go to their fleet, tap on the three-dot menu at the top right corner. 

Then tap on Mute. 

Who can see my fleets?

All fleets appear at the top of your Home timeline for all your followers to see. If you are tweets are public, people will also be able to access them through your profile photo on your profile page. But if your tweets are protected, so will be your Fleets.

That is all there is to know about Twitter’s latest fleet feature. No more would you have to keep yourself from sharing your momentary thoughts about something that you care about. 


What Is Alt Control Delete On A Macbook

If you’ve recently switched to Mac from Windows, or you just need to know Mac equivalent Windows shortcuts, you have surely noticed many differences between the two operating systems. However, Windows and Mac do share some of the basic shortcuts. 

One of the most handy shortcuts in Windows is the Alt + Ctrl + Del hotkey, which lists a menu of different options. The good news is, this shortcut is also present in Mac, albeit it functions a little differently.

What is Alt Control Delete on a Mac?

The Alt + Ctrl + Del shortcut key in Mac is Command + Option + Esc key. The two hotkeys share similar keys in different operating systems, but their functions vary a little.

The Alt + Ctrl + Del key used to open Task Manager in previous Windows versions. However, in the newer version of Windows, this shortcut key opens a list of options, such as locking the computer, changing the password, signing out, switching users, and also opening Task Manager.

On the other hand, the Command + Options + Esc key opens up the Force Quit Applications window on Mac.

We usually use the Alt +  Ctrl + Del Key to open Task Manager and forcibly close unresponsive applications or refresh the system if it freezes. In Mac, the Command + Options + Esc shortcut also does the same via Force Quit Applications.

If you want to know how you can force quit any application or refresh the system using Command + Options + Esc hotkey, follow the steps below:

While the Command + Options + Esc shortcut key doesn’t cover all the functionalities of the Alt + Ctrl + Del hotkey, it does emulate its main function. For the other list of options provided by this hotkey in newer versions of Windows, you can do the similar thing on your Mac system on the following way:

Task Manager Equivalent in Mac

The Force Quit Applications does emulate one of the main functions of Task Manager, but it doesn’t cover all of it. The actual equivalent of the Windows Task Manager on Mac is the Activity Monitor, which has all the same functionalities as Task Manager. 

To open the Activity Monitor on Mac, follow the steps below:

Troubleshooting Command + Options + Esc Shortcut Not Working Issue

If the Command + Options + Esc doesn’t work on your Mac, it could be due to issues like problematic hardware or misconfigured settings. The first thing you should do to troubleshoot this issue is to check your keyboard hardware.

If some of the modifier keys like Command and Option aren’t working themselves, your shortcut keys that rely on these keys will also not work.

The other reason why your Command + Options + Esc key is not working can be due to modifier keys being remapped. You could have accidentally remapped your keys or some application may have done so. If this is the case, the shortcut still works, you just need different button presses.

To bring it back to default, you can try resetting your keyboard to default key mapping.

What Exactly Is Focus Mode On The Iphone?

In fact, Apple has been thinking about this for a long time. What we know as Focus Mode incorporates many game mode features. On Focus Mode, users can set up an exclusive page for games. They can also hide this page to avoid from affecting the layout and use of the normal main interface. When we do this step, we have ushered in the very critical “focus mode” setting. We can set a separate “game mode” in focus mode. In this mode, we set to show only the game desktop that is hidden by us.

Focus Mode brings decent operations

Focus mode can also block notifications and incoming calls. Users can decide to select the application notification that they need. In fact, we can permit incoming calls from specific numbers. After completing a series of settings, it will surprise us to know that we can game mode features in through the focus mode. We ca use certain Focus Mode settings to enjoy “off-duty mode”. This mode goes beyond just blocking calls or restricting messages. 

For example, when you meet your girlfriend, you can turn on the “love mode” to automatically hide all sensitive application pages. You can set the timer for the “love mode” to activate so all sensitive pages automatically hides. There is an automatic operation that makes the focus mode smarter. When we get home from get off work and enjoy the time off work, while turning on the “off work mode”, automatic operations help us turn on the air conditioner, close the curtains, and turn on the TV. To put it simply, the off-duty mode is automatically turned on when you get home. Similarly, when you step out of the home, the off-duty mode automatically turns off .

After so many years, Android still can’t do “focus mode” well

The original intention of this function is good, and the market feedback is also very good. Many users say that they can concentrate more on work and study, and can also avoid staying up late at night.

In addition to OnePlus, there are several other Android manufacturers that has made good attempts. However, most of these options has some serious lapses. There is one that put the smartphone into automatic flight mode after locking the screen. Bamuda’s mobile phone screen automatically mutes notifications, focusing on work. Although they all have their own characteristics, they are all a function of treating the symptoms rather than the root cause. These are far inferior to the “meditation mode” of OnePlus. After so many years, Apple now has a new Focus Mode and it does it better. 

Apple does it better

The option of automatically disabling smartphones is just like learning for elementary school students. You don’t need to care about what you want to learn, and you can’t learn if you don’t want to learn. How to improve your self-control is the foundation of everything. Smartphones bring distractions but this doesn’t mean users do not need some information. Apple’s Focus Mode give users the option of choosing what to deactivate. This mode is so specific that it completely defeats any previous option in the market. 

In Apple’s eyes, mobile phones have long been an inseparable product. Since you can’t refuse, enjoy it. Therefore, Apple divided the modes required for various time periods and launched the function of “focus mode” to better integrate mobile phones into life, subdivide usage scenarios, and provide greater convenience. The only problem with Focus Mode is the “learning cost”. I personally think the learning cost of “focus mode” is too high. In today’s impetuous society, many users do not have so much time to learn the use of a new function. If you have time to think about it, the “focus mode” will definitely help you a lot.

What Is Grey Arrow Check On Snapchat And What To Do About It?

Snapchat, like most other social media apps, has a language of its own. In order to master the app, you must understand the ins and outs of it. Among its exhaustive list of indicators, the grey arrow is slightly less known.

We all know about the red, blue, and purple indicators on the social media app. But in this post, we are going to cover the grey arrow on Snapchat; what it is, and what you can do about it. Also, what the hell is a grey arrow check?

What are Snapchat indicators?

Snapchat indicators are meant to show the status of sent media; whether it is a photo, video, or text. Each of these formats has its own indicator. The indicators are just as useful to the sender as they are to the receiver.

A sender can figure out what they have sent, and if that content has been, opened, viewed, read, or not touched. A receiver, on the other hand, can tell the content of the sent media by simply looking at the indicator. They can tell whether they have been sent a photo, a text message, or a video, without even opening it up!

These indicators appear right below the user’s name and change depending on the state of the sent content.

What is a grey arrow on Snapchat?

The grey arrow is one such indicator on Snapchat. This indicator is seen much less often as compared to its colored counterparts. That is because the indicator only appears when content is not delivered.

Unlike the ‘Sending’ notification which is meant to indicate that your network is unable to send the snap through, the grey arrow indicates that the user cannot accept communications from you.

This could be either because they have not accepted your friend request yet or have unfriended you on the app. There is no way to isolate the cause of the grey arrow, for privacy reasons. But it clearly indicates that the user cannot be contacted by you. If you have been unfriended by a user, the grey arrow will appear irrespective of whether you try to send a snap, video, or text message.

What is a grey arrow check?

Well, now that we know what a grey arrow means on Snapchat, the grey arrow check isn’t too far off. The term is used to describe the action of checking if someone in your friends list has unfriended you. Snapchat does not notify you when someone unfriends or blocks you on the app.

The grey arrow check is basically sending out a snap to a bunch of people to see whose name will have the grey arrow below it. Since the grey arrow indicates that you cannot communicate with the person, whoever’s name shows up with a grey arrow means that they have unfriended you or are yet to accept your friend request.

What happens if the person re-friends you?

As outlined above, the grey arrow is an indication of a user unfriending you. The arrow will remain grey on your account, and the content will not be delivered to the other person. If at some point the person adds you back as a friend, then two things will happen:

You will be sent a notification that they have added you as a friend. This is an immediate tell that the person had unfriended you at some point.

Your grey arrow will change to a colored one (depending on the media you are sending). This means that your snap will go through, and the person will be able to view it.

What can you do about the grey arrow?

Unfortunately, there is no way to force a snap through if the person has unfriended you. If you believe it to be a mistake, you can contact the person and let them know, so that they can re-friend you. However, you will not be able to do so on the Snapchat app, so you will need to contact them using another app.


What Is A Vpn And What Is It Used For?

A VPN, or Virtual Private Network is an extremely useful tool for every internet user, no matter how much time you spend online or what sort of stuff you do on the internet. A VPN gives you more security and privacy when you go online – things that are hard to come by in today’s information age. 

Table of Contents

What Is a VPN and How Does It Work?

If you have a general idea of how the internet works, you probably know that your internet service provider (ISP) and some other organizations have ways of tracking your online activity. Your browser’s private browsing mode can’t help protect your data and give you peace of mind, while a VPN can do more than that.

VPN is a technology that protects your online activity by adding an extra level of encryption to your data. It connects your computer or a smartphone to a private network, allowing your data to go through an encrypted “tunnel”.

It travels from your device to some other point on the internet, often in another country, before making its way to the public internet. Your data stays hidden the entire time. All an ISP can see is that you’re connected to a private network. 

When you connect your device to a VPN, it behaves as if it was on the same local network as the VPN. It allows you to access local network resources even if physically you’re accessing the internet from a different country. You can also browse the internet as if you were based at the VPN’s location. For example, if you’re using a USA-based VPN from outside the US, the websites will see your online activity as if it was coming from within the country. 

What IS a VPN Used For?

Some people associate using a VPN with the need to hide your online activity. In reality, a VPN comes with a number of benefits that can help any internet user in their everyday life. Here are a few reasons why you might want to start using a VPN.

Secure Your Connection When Using Public WiFi

When you’re browsing the internet at home, your connection is via a password-protected router and a private WiFi network. However, when you connect to a public WiFi network – whether it’s at a coffee shop, a hotel, or an airport – your traffic isn’t protected anymore. Those networks offer open access to all users, which makes it much easier to intercept the wireless network traffic. 

That’s why it’s a good idea to use a VPN next time you decide to connect to a public WiFi network to send an email or check your Instagram account. 

Take Back Your Online Privacy

Using a VPN is one of the simplest and most effective ways to gain back your online privacy and stop others from collecting your data.

Access Geo-Blocked Content 

One of the most popular reasons for getting a VPN service is to access geo-blocked websites. Sometimes you’ll find that certain content, streaming services, or websites are blocked or have restricted access based on your location. Using a VPN is the easiest way to bypass those restrictions. 

This can be useful if you ever find that certain movies or TV shows aren’t available on your streaming platform in your region. Connecting to a VPN server from the appropriate country can easily fix that. 

When traveling, you might find yourself in a country where entire websites and services are geo-blocked. For instance, if you want to access LinkedIn in Russia, you’ll have to use a VPN or other means of getting around geo-restrictions. 

Bypass Your School or Workplace Firewall

When using the internet at your school or workplace, you’re bound to come across blocked websites that management doesn’t want you to access. They do this by using firewalls that filter all web content and keep you away from the blacklisted sites. 

There’s a number of workarounds that can help you bypass your school or workplace firewall. One of the easiest ways to do it is via the VPN service. When you connect to a VPN and start browsing, all the internet traffic is encrypted, and the firewall can’t see what you’re doing and what sites you’re visiting on the network connection. This way you can view the sites you want no matter the time and place.

Save Money on Shopping

Aside from the obvious benefits you get from using a VPN, you can get some extra perks if you think outside the box. A VPN can help you save money on shopping. Admittedly, it does require some time and effort.

You can use a VPN to connect to different servers across the world and find the cheapest prices. The things you can save money on include streaming services, software subscription plans, flight tickets, and even hotels. In theory, you can find cheaper prices for everything. However, don’t forget that some of the price differences will be covered by exchange rates and bank fees. 

Do You Need a VPN?

While VPNs come with many benefits, they’re not flawless. The biggest downside of using a VPN is a connection speed drop. Since you’re sending your data to another location before it reaches the right server, your VPN connection speed is bound to be slower than your regular internet speed. 

However, if that’s not a big problem for you, or if the connection speed drop isn’t significant, using a VPN is definitely a good idea. All that’s left is to choose the right VPN service for you. Luckily, there are plenty of options out there – from a Windows built-in option, VPN Chrome extensions, best free options for Mac, and the best VPN apps out there.
