Voter card verification

নির্বাচন কমিশন ১লা সেপ্টেম্বর থেকে নির্বাচকের তথ্য যাচাই করণ প্রক্রিয়া শুরু করেছে। এই প্রক্রিয়া চলবে আগামী মাসের ১৫ তারিখ অর্থাৎ ১৫ই অক্টোবর পর্যন্ত। এই প্রক্রিয়াটি সম্পন্ন করতে পারবেন যে কেউ বাড়িতে বসেই নিজের স্মার্টফোন থেকে। এর জন্য আপনাকে ডাউনলোড করতে হবে কেবলমাত্র একটি মোবাইল অ্যাপ। যা ভারতীয় ইলেকশন কমিশন ইতিমধ্যেই গুগল প্লে স্টোরে আপলোড করে রেখেছে।সেজন্য আপনাকে প্রথমে গুগল প্লে স্টোরে যেতে হবে, সেখানে ‘Voter Helpline’ নামে একটি মোবাইল অ্যাপ রয়েছে যেটি ডাউনলোড করতে হবে। ডাউনলোড করার সময় অবশ্যই দেখে নিবেন অ্যাপটি নির্বাচন কমিশন দ্বারা প্রদত্ত কিনা, অন্য কোন সংস্থার দ্বারা আপলোড হয়ে থাকলে সেটি ডাউনলোড করবেন না। কারণ তাতে আপনি প্রতারণা সম্মুখীন হতে পারেন। আর যদি কারোর এই অ্যাপটি আগে থেকেই ডাউনলোড করা থাকে তাহলে অবশ্যই আপডেট করে নিন।

Applications of DBMS

Database is a collection of related data and data is a collection of facts and figures that can be processed to produce information.Mostly data represents recordable facts. Data aids in producing information, which is based on facts. For example, if we have data about marks obtained by all students, we can then conclude about toppers and average marks.A database management system stores data in such a way that it becomes easier to retrieve, manipulate, and produce information. Following are the important characteristics and applications of DBMS.ACID Properties − DBMS follows the concepts of Atomicity, Consistency, Isolation, and Durability (normally shortened as ACID). These concepts are applied on transactions, which manipulate data in a database. ACID properties help the database stay healthy in multi-transactional environments and in case of failure.Multiuser and Concurrent Access − DBMS supports multi-user environment and allows them to access and manipulate data in parallel. Though there are restrictions on transactions when users attempt to handle the same data item, but users are always unaware of them.Multiple views − DBMS offers multiple views for different users. A user who is in the Sales department will have a different view of database than a person working in the Production department. This feature enables the users to have a concentrate view of the database according to their requirements.Security − Features like multiple views offer security to some extent where users are unable to access data of other users and departments. DBMS offers methods to impose constraints while entering data into the database and retrieving the same at a later stage. DBMS offers many different levels of security features, which enables multiple users to have different views with different features. For example, a user in the Sales department cannot see the data that belongs to the Purchase department. Additionally, it can also be managed how much data of the Sales department should be displayed to the user. Since a DBMS is not saved on the disk as traditional file systems, it is very hard for miscreants to break the code.

What’s new in Android 11 ?

Source: Tech AedgarThe Android 11 Developer Preview phase may have started, but that doesn’t mean we haven’t already got a growing wish list of features that we want to see in the full build.Over the past few years, we’ve seen Google listen to feedback and community input to add some highly anticipated options to the mobile OS. We’re at a point now where complete wholesale changes are not really that necessary.It’s still a game of tweaks and improvements as, naturally, Android feels so much more robust and complete than at any other time, thanks to constant improvements and enhancements. That has made it harder and harder to see just what needs to be added, rather than what we would like to be added to our favorite mobile OS.One thing is clear, though: There are a ton of features that already exist on other third-party versions of Android that still need to come to the “stock” implementation or core build. The first Android 11 Developer Preview gave us a glimpse of some, but we’re expecting more as they rack up.With more expected and undoubtedly some unexpected features coming within these developer-focused updates, we’re still hoping to see some additions from our Android 11 wish list prior to the full release later this year.Customizable back gesturesGesture navigation on Android hasn’t had the smoothest start, especially with the many apps that utilize the side hamburger menu. OxygenOS on OnePlus devices had a fantastic implementation of the Android 10 gestures that would only be usable within a certain region of the left and right side of your device.For whatever reason, that has since been removed, and now any devices that are running Android 10 will still have issues with the back gesture, with apps that use a side hamburger menu. So, that means near the very top of our Android 11 wish list is the ability to customize the back gesture. It would be nice to be able to have it work on just one side of the device or have activation zones for when you will go back.Clipboard managerGboard now has a clipboard manager, but how about a native systemwide option for Android? It would be great to be able to sift through recently copied text and images, should you want to share them again. We know that some third-party skins include the option already, but with the right security steps, it could be a really useful addition tool.Better backupsBackups on Android have improved but really are in a sorry state for the most part. Full backups that include MMS messages are possible with the help of a Google One subscription, but that isn’t a proper solution.A full backup solution that allows secure backups of all apps on a device would be great for when you need to restore or change your device. At the moment, there are some workarounds, but this is something we’ve needed for a long time in the core OS.One-handed modeA frustration for anyone that prefers Google’s “stock” implementation of Android over other third-party versions is that we simply don’t have a proper one-handed mode. It’s almost embarrassing that Google hasn’t added an option yet when there are some exceptional accessibility options already in Android 10.Google Assistant without unlockingIf you already have Voice Match enabled on your Google account, then it would be neat to not have to unlock your device just to use the Assistant. It’s especially annoying when you want to do things like controlling your smart home lighting or set a reminder. It’s even more annoying when you’re driving and want to keep your eyes on the road.Further theme controlsThe current crop of theming controls are nice and all, but how about more controls like the ability to change wallpaper or icon style when the native dark theme is enabled? On top of that, it would be nice to get new fonts beyond the limited selection, let’s also see custom accent options find its way into the full Android 11 release too.Contextual auto-rotateWith the new Soli radar chip and better internal sensors found in the Pixel 4, it would be fantastic to have proper contextual auto-rotate like you’ll find in the Mate 30 Pro. Although that utilizes the 3D face-scanning tech to work out which way you are oriented and then rotates the screen accordingly, Google doesn’t even need to go to those lengths.We’d love to see the option for videos to auto full-screen in apps like YouTube or even the Google Camera UI — thereby forcing you to take photos and video in landscape rather than portrait.Camera quick-launch shortcutsNear the very top of my Android 11 wish list is the ability to create camera app shortcuts, kind of like how you can create shortcuts or hyperlinks on your home screen for websites and Progressive Web Apps. It would be fantastic to be able to launch directly into Night Sight or 4K video recording. It would save time when you just want to take a quick snap or record a short video, allowing you to just capture a fleeting moment without needing to scroll through settings.Enhanced Wi-Fi auto-connect settingsI need to explain this a little as this as it’s a bit of a unique problem. Much like you can set your device to use mobile data when your Wi-Fi connection is poor, you should be able to auto-connect to Wi-Fi networks in a similar manner. At the moment, there isn’t an option to disconnect from a network if it’s slow, you have to do it manually.If you work in a large office or facility, this might be a problem, but it could easily be remedied with some software tweaks in Android 11.Desktop modeThis is probably low on many wish lists out there, but we really hope that we finally get to see a proper desktop mode come to the full Android 11 release. Google could offer a proper Chrome OS-style experience that would put Samsung’s DeX to shame with just a little work.What’s on your Android 11 wish list?Is there anything you’d love to see in the next iteration of Android? Any niggling little issues that bug you when using your device? Let us know down in the comments section below.
