Below is an in-depth review based on the platform’s current features, user experience, and market positioning.

1. Core Concept and Philosophy

Unlike Khan Academy or Brilliant, which focus heavily on instructional content and lessons, Equathora is built on the philosophy of “learning by doing.” It serves as a digital “notebook” that tracks your thought process.

Active Over Passive: The site assumes you have some foundational knowledge and provides the venue to apply it through curated problem sets.

Step-by-Step Engagement: Rather than just entering a final answer, the platform encourages users to work through problems using a built-in math editor, aiming to simulate the experience of solving on paper but with the benefits of digital tracking.

2. Key Features

• Live Math Solver (MathLive): This is the platform’s standout technical feature. It uses a LaTeX-style input system that allows users to type complex mathematical notations (fractions, matrices, exponents) directly in the browser.
  Curated Problem Library: Problems are organized by topic (Algebra, Calculus, Logic, etc.) and difficulty. The library currently hosts 100+ problems, with the developer actively expanding the set.
  Gamification (XP & Achievements): To maintain user retention, Equathora employs a leveling system. You earn XP for correct answers and unlock over 30 unique badges (including “Founder” badges for early adopters).
  Leaderboards: Users can compare their progress against others based on problems solved and topics mastered, adding a competitive edge to study sessions.
  Progress Tracking: The dashboard provides a “Completion State,” allowing you to pick up exactly where you left off, which is a significant quality-of-life feature for long-form problem sets.

3. User Experience (UI/UX)

The interface is clean, modern, and distraction-free—intentional for a subject that requires high focus.

• Desktop vs. Mobile: While originally launched as an MVP with some mobile scaling issues, recent updates (January 2026) have significantly smoothed the mobile experience and increased page load speeds by roughly 40%.
  Dark Mode & Aesthetic: The site uses a professional color palette that avoids the “childish” feel of many educational apps, making it more appealing to college-level users.
  Sketch Pad: A recent addition is a drawing canvas that allows users to visualize geometry or logic problems manually before entering their LaTeX solution.

4. Strengths

• Human-Centric Feedback: The developer has emphasized a move toward “Mentor Mode,” where human feedback (rather than just AI-generated hints) plays a role in the learning process.
  Zero Paywall (Current): As of early 2026, the platform is largely free, with a focus on building a community of “power users” before introducing premium tiers.
  Data Portability: Unlike many locked-in ecosystems, Equathora allows users to export their progress and stats as PDF or CSV files.

5. Areas for Improvement

• Content Volume: With ~100 problems, advanced users may burn through the content quickly. The success of the platform will depend on the speed at which the problem bank scales.
  
  Explanation Depth: While it provides step-by-step solutions, it currently leans more toward what the answer is rather than the why of the underlying theory. Users looking for deep conceptual explanations might still need a secondary resource.
  Community Size: The platform is in its early stages (approx. 50+ on the official waitlist and a growing beta group), meaning leaderboards and community features are not yet as “active” as more established sites.

6. Final Verdict

Rating: 4/5 (for Early Stage MVP)

Equathora is an excellent tool for the “serious” math student—specifically those preparing for Math Olympiads (AMC 12, etc.) or early undergraduate STEM courses. It removes the friction of finding quality problems and provides a superior input method compared to standard multiple-choice platforms.

Who is this for? * Students who find Khan Academy too easy or repetitive.

• Competitive math participants looking for a structured daily challenge.
• Self-learners who want a digital record of their mathematical “journey.”

How to join: The site is currently in an open beta/waitlist phase. You can access the dashboard at equathora.com/dashboard to start solving, though joining the waitlist is recommended to secure “Founding Member” status and early access to the upcoming mentorship features.

You must be careful while deleting a file because once a file is deleted it is hard to recover its content.

In this quick guide, we will demonstrate to you the methods of deleting files in Ubuntu 24.04. Let’s continue without wasting any further time.

How to delete a file in Ubuntu 24.04

Open up the terminal from Show Apps or by using the shortcut key CTRL + ALT + T.

Method 1. Using rm command

One of the simplest methods of removing files is by using rm command. In reality, the rm command looks like.

rm filename

If you want to delete multiple files, the command should be written on the terminal as follows.

rm filename1 filename2 filename3

Examples

Suppose the file you want to delete is new_linux_world.txt and it is located in your current directory, execute the below command.

rm new_linux_world.txt

Similarly, you can delete multiple files by specifying the file names with rm command. 

Suppose, there are two files new_linux_world.txt and old_linux_world.txt you want to delete. The command should look like this.

rm new_linux_world.txt old_linux_world.txt

Method 2: Using unlink command

Unlink command can also be used to delete files in Ubuntu 24.04. However, it is less handy as compared to rm command because it cannot delete multiple files. The syntax of the unlink command looks as follows.

unlink filename

Example

For the sake of understanding, let’s delete a file new_linux_world.txt placed in your current directory. Execute the following command on the terminal.

unlink new_linux_world.txt

Method 3. Using shred command

When you remove a file with the rm command, the file is still recoverable. But when you use the shred command, the file is overwritten multiple times with random data and becomes unrecoverable.

Example

To delete a file new_linux_world.txt with the shred command, type the following on the terminal. Assuming your file is kept in your current working directory.

shred new_linux_world.txt

Conclusion

So, you have read the different methods to delete your file in Ubuntu 24.04. Depending on your requirements, you can use rm, unlink, and shred commands. Although they all do the same task, they have little difference.

What is DNS and how does it work?

DNS stands for Domain Name System. It is a system
that allows you to assign readable names to the IP addresses of devices connected to the Internet. In this way, users can access websites, online services, or network resources using easy-to-remember names, such as www.bing.com, rather than long and complex numbers, such as 204.79.197.200.

The way DNS works is based on a hierarchy of servers distributed around the world. They store and update information about names and associated IP addresses. When a user enters a domain name in his browser, the DNS system looks up the server that contains the information about that domain and returns the IP address. Thus, the browser can then establish a connection to the server hosting the requested website and display its content to the user.

How to use AdGuard’s DNS service on your Android phone

The AdGuard DNS is an alternative service to the one offered by our Internet provider or our router. In addition to performing the basic function of resolving domain names, it also filters the requests that are made to advertising and tracking servers. Preventing them from being loaded on our device. Thus, we can surf the Internet without seeing ads or being tracked by third parties.

Follow the steps below to use the AdGuard DNS service:

First step

Go to the Settings application on your Android phone.

Second step

Then go to Network & Internet>Advanced>Private DNS. You can get to this option easier and faster by typing “Private DNS” in the search box of the Settings app.

Third step

After that, once you have selected Private DNS, tap on “Private DNS provider hostname”.

Fourth step

Now, you have to enter the AdGuard DNS address:

dns.adguard.com (to block advertising and tracking).

Fifth step

Finally, click on Save and that’s it!

With these steps, you will have already activated AdGuard DNS on your Android device. And you can enjoy cleaner and safer browsing. Of course, keep in mind that this method only works if you have Android 9 or higher, and that it may not be compatible with some public or private WiFi networks that require specific configuration.

Alternatively, you can activate this DNS from a more intuitive interface with the AdGuard app that you can download from Google Play.

Google Play | AdGuard for Android

Is it safe to use the AdGuard DNS service?

The dns.adguard.com is a public DNS service that protects against tracking, phishing, and malware. According to its website, dns.adguard.com uses encryption and does not keep any logs of user queries. However, as with any DNS service, there is a risk of bugs, unwanted failures, delays, or crashes. It is therefore recommended to
use dns.adguard.com with caution and verify its reliability and performance before relying on it for browsing. Thank you for reading us. Goodbye!

What is a VPN and what is it for?

Let’s start with a brief review of what a VPN is, for all those people who are not very clear about this concept. VPN stands for Virtual Private Network, which, in simple terms, is a space created with an extension of your local connection that hides your real location and encrypts your data.

In other words, a VPN is a security tool that hides your data from any software that wants to access it. It also alters your IP to make it look like you are connected from somewhere else. The intention is to keep your data safe from any malicious website or person. Opera offers its users a completely free VPN that is already included in its browser.

VPNs have many advantages, however, they are not perfect and there are some not-so-beneficial aspects of using VPNs. We invite you to read on to learn more about these private networks.

How to activate Opera VPN on Android?

The VPN button is within easy reach and you just have to press it to activate it every time you want an extra touch of security in your browsing.

To activate Opera VPN on an Android phone, follow the steps below:

First step

Download and install Opera browser by following the link below:

Google Play | Opera browser with AI

Second step

Then log in to the Opera browser and click on your profile icon in the lower right corner.

Third step

After that, select the option that says VPN.

Fourth step

Once you have activated the VPN for the first time, you can check the settings to make sure they are correct. The next time you want to access these settings, you can press and hold the VPN icon.

Fifth step

Finally, you can choose the virtual location, which defaults to America. You can also set the VPN to be active only for incognito windows. And that’s it!

Just like that, the free VPN of the Opera app on Android will be activated. It’s important to mention that this VPN doesn’t have a lot of customization options, however, it does the main job, that is, protecting your data.

Is it possible to activate a free VPN in Opera GX and Opera Mini?

Opera has several versions of its browsers, each version has a different mission and has different functions, depending on what its users are looking to achieve. The other versions of Opera are Opera GX and Opera Mini, both of which are very good alternatives, but neither has a free VPN integrated. So if you want to be able to have a VPN while using some of these other two versions of Opera, you will have to resort to a third-party VPN. But don’t worry, there are many other free VPNs for Android, you just have to find the one that works best for you. Thanks for reading. Goodbye!

The best option is to delete the Telegram cache using the app itself

The cache is a part of the phone’s internal storage in which certain files are stored. Of a temporary nature generally, they serve to optimize the performance of the apps. However, they can end up being counterproductive if they take up too much space. That is why freeing this memory is key on many occasions, especially in the case of apps that consume as much space as Telegram.

As standard, we know a generic method to clear the cache memory of apps on Android, which is to go to the phone settings. However, Telegram is one of the exceptions in that it is also allowed to empty from the app and more effectively. And the latter is not a saying, since, as you can see, you can delete much more data than from the phone settings.

So that you can achieve your task and delete your Telegram cache, you just have to follow the following steps:

First step

In Telegram, open the drop-down menu on the left. Then enter the “Settings” section.

Second step

After that, go to the “Data and Storage” section.

Third step

Next, now click on “Storage usage”.

Fourth step

Finally, press the “Clear cache” button.

Don’t forget to set limits for Telegram

After you already know how to clear the cache manually in Telegram. Perhaps it is also interesting to set a limit so that it does not occupy more than a certain amount of space. So you will not have to be constantly aware of the memory occupied by the application.

To achieve this, you must return to the same menu as before (Data and storage). But instead of just hitting the “Clear Cache” button. You should slide down and until you see the “Maximum cache size” option. The convenient thing to do would be to move the bar and set it to 5 GB, which is the minimum you can set. Another setting that may benefit you is to disable the automatic downloading of media files. This way, when you receive a lot of files they will not be downloaded automatically. And you can manually choose which files you want to download. This setting can also be found in the “Data and Storage” section.

Once you have followed the steps in this article. It is advisable to keep checking the cache space occupied by Telegram from time to time and you can delete it if you see it necessary. However, you can now rest easy knowing that it will not get out of control. At most, it will take up 5 GB, which is already quite a lot in itself. Thanks for reading. Goodbye!

Blocking the permanent mobile data connection

Wireless connections are an essential part of smartphones, especially after the progressive popularization of apps connected at all times. Android searches for a tower to connect to, tries to locate known WiFi networks and, on top of that, performs both tasks constantly and by default. Restricting this operation will have positive effects on battery saving without wasting more than a few minutes each day.

Increasing battery life is possible with two hidden settings on your Android that will help you.

In the Developer Options, several settings allow you to get some more autonomy. And two of these options are practical: “Mobile data always active” and “Wi-Fi scan throttling”. Both are intended to reduce the time away from an active Internet connection, but they can be switched off without reducing the usage experience too much. We find this highly recommended.

Here’s how to disable both network features from Developer Options:

First step

To begin with, it is essential to enable the “Developer options”. To do this, go to the settings of your Android. Then find the “About phone” section. Next, locate the “Build number” and press that option 7 times until you see a message saying “You are now a developer”. This activates the “Developer options”. There is a possibility that you will have to authorize unlocking your phone.

Second step

Then go back to the main “Settings” menu and go to the “System” section to locate the new “Developer options”. For each brand of phone, this may vary: they are usually located under “System”.

Third step

After that, swipe down in the Developer Options menu until you find the “Wi-Fi scan throttling” setting and enable it.

Fourth step

Finally, just look for the “Mobile data always active” option and turn it off. And that’s it!

Conclusion

By configuring these two functions of WiFi and mobile connectivity in the background your Android device will stop searching for networks constantly and, when connected to a known WiFi, it will disable mobile data so as not to waste resources when they are unnecessary (you can also completely disconnect the WiFi and activate it only when you are under your known networks). In return, it may take a few seconds longer than usual for your phone to connect to the Internet when you leave the WiFi coverage, nothing that would be problematic. Remember to try these options and let us know your experience in the comments. Thanks for reading us. Goodbye!

StandBy iOS: the app to get the new iOS 17 feature on your Android phone

StandBy iOS is a free application with ads that you can find in the Play Store (below is the download link). This app is activated when you charge the Android phone and works very similar to the StandBy mode of iOS 17. It has a variety of clock styles that are customizable and widgets calendar and weather. It also has a paid version that removes ads and offers unique clock layouts.

How to install iOS 17 StandBy Mode on your Android phone

You need to make some settings for the StandBy iOS app to work properly on your Android phone. We recommend you follow the steps below:

First step

Download and install the StandBy Mode iOS app from Google Play by following the link below:

Google Play | StandBy iOS: Always On Display

Second step

Then what you have to do when you open the app is to click on the Settings button and then enable the option “Quick launch when your device is plugged and charging”.

Third step

After that, the app will take you to your device settings where you have to grant the app permissions for “Display over other apps” and permission to “send you notifications”.

Fourth step

Once this is done, you can start customizing the Standby Mode. With the Quick Navigation button that you will see in the app interface, you can choose between the different clock styles and colors. And when you are done with the customization, the only thing you will have to do is to connect the phone to the power and this will activate this standby mode similar to that of the iPhone.

What makes this app stand out from the handful of iOS 17 sleep mode clones that are already populating Google Play? Is that it’s pretty polished in that it can be set to automatically launch when you put the phone on charge. Something we haven’t seen in other similar apps. In addition, it has a feature that allows you to protect the screen against a possible burn. As we commented, you can try the app without problems without paying and ads appear very occasionally. However if duplicate iOS 17 sleep mode is something of interest, you can always opt to purchase the Pro version which you will surely not regret. Thanks for reading us. Goodbye!
