Coding Bit Mobile App Development

Coding Bit Mobile app development is the process of designing and building software applications that run on mobile devices such as smartphones and tablets. There are three main types of mobile apps: native, cross-platform, and hybrid. Native apps are developed specifically for a single platform such as Android or iOS using platform-specific programming languages like Katlin or Swift. Cross-platform development allows developers to write one codebase that works on multiple platforms using frameworks like Flutter (which uses Dart) or React Native (which uses JavaScript). Hybrid apps are essentially web apps wrapped in a native container, often built with technologies like HTML, CSS, and JavaScript using frameworks like Ionic or Cordova. The development process involves both frontend (user interface and experience) and backend (server, database, and API integration) components. Tools such as Android Studio, X code, and Visual Studio Code are commonly used depending on the platform and framework. Essential concepts in mobile development include UI design, navigation between screens, state management, user authentication, and connecting to databases or web services. Overall, mobile app development requires a blend of design skills, programming knowledge, and an understanding of mobile platforms to create functional and engaging applications.

Researchers Uncover Widespread Vulnerability in Open-Source Package Ecosystems

Checkmarx Researchers have discovered a concerning vulnerability that spans multiple open-source programming ecosystems, including PyPI, npm, Ruby Gems, NuGet, Dart Pub, and Rust Crates. This discovery highlights a potential avenue for sophisticated software supply chain attacks that could have far-reaching consequences for developers and enterprises. The Nature of the Threat The vulnerability centers around exploiting entry points, a feature common in many programming languages that allow developers to expose functionality as command-line wrappers or load plugins to enhance package capabilities. While designed to improve modularity and flexibility, these entry points can be manipulated by malicious actors to execute harmful code when specific commands are run. Command-Jacking: A Stealthy Attack Vector One of the primary techniques identified by researchers is "command-jacking." This method involves creating counterfeit packages that use entry points to impersonate popular third-party tools and commands. When unsuspecting developers install these packages, sensitive information can be harvested, even if the package is distributed as a wheel (.whl) file. Potential targets for command-jacking include widely-used commands such as npm, pip, git, kubectl, terraform, and dotnet. Additionally, attackers may exploit legitimate system command names like touch, curl, and ls as entry points to hijack execution flow, particularly in development environments where local package directories take precedence in the PATH order. Command Wrapping: Enhancing Stealth and Persistence An even more insidious variation of command-jacking is "command wrapping." This technique creates an entry point that acts as a wrapper around the original command, executing malicious code while invoking the legitimate command and returning expected results. This approach makes detection extremely difficult, as there are no immediate signs of compromise during normal use. Using Python Entry Points to manipulate CLI commands: https://www.youtube.com/watch?v=-GTOOrYniFE Malicious Plugins: Compromising Developer Tools Another attack vector involves creating malicious plugins and extensions for developer tools. These rogue additions can gain broad access to codebases, allowing attackers to alter program behavior or manipulate testing processes to conceal their activities.

The Scope of the Problem

The discovery of these vulnerabilities comes at a time when the threat landscape for open-source ecosystems is rapidly evolving. Recent data from Sonatype's State of the Software Supply Chain report indicates a staggering 156% year-over-year increase in malicious packages discovered across Java, JavaScript, Python, and .NET ecosystems since November 2023, totaling over 512,847 packages. Challenges in Detection and Prevention What makes these new attack methodologies particularly concerning is their ability to bypass traditional security measures. Many existing tools fail to detect these sophisticated supply chain attacks, leaving both individual developers and automated build environments exposed to significant risk.

Moving Forward: Securing the Software Supply Chain

As the threat landscape continues to evolve, the cybersecurity community must develop comprehensive security measures that account for entry-point exploitation. This will require a multi-faceted approach, including: - Enhanced monitoring and validation of package ecosystems - Improved developer education on supply chain security risks - Development of new tools capable of detecting sophisticated attack patterns - Collaboration between package maintainers, security researchers, and platform providers By addressing these risks head-on, the open-source community can work towards creating a more secure packaging environment that safeguards both individual developers and enterprise systems against the next generation of supply chain attacks.

I was trying to do some Index writing speed improvement and thought of creating a asynchronous Lucene index writer. This writer provides a addDocument() method which can be called asynchronously by multiple threads. Here are the few scenario where you can utilize this implementation - Reading the data is slower then writing to the index. (Typical scenario where you read over network, or from database.) - Reading can be divided in multiple logical parts which can be processed in separate threads. - You are looking for asynchronous behavior to decouple reading and writing processes. This implementation is a wrapper which utilizes core methods of IndexWriter class, and does not do any change to it except making it asynchronous. It utilizes Java's java.util.concurrent.BlockingQueue for storing the documents. It can be supplied with any implementation of this class using its constructor. Below is the Java source of this implementation class This class provides multiple constructors to have better control. Few terms which are used here are as follows Sleep Milliseconds On Empty: This is the sleep duration when writer finds nothing in queue and wants to wait for some data to come in queue. () Queue Size: This is the size of the queue which can be configured as a constructor parameter input. AsynchronousIndexWriter.java package swiki.lucene.asynchronous; import java.io.IOException; import java.util.concurrent.ArrayBlockingQueue; import java.util.concurrent.BlockingQueue; import org.apache.lucene.document.Document; import org.apache.lucene.index.CorruptIndexException; import org.apache.lucene.index.IndexWriter; /** * @author swiki swiki * */ public class AsynchronousIndexWriter implements Runnable /* * A blocking queue of document to facilitate asynchronous writing. */ private BlockingQueue documents; /* * Instance of core index writer which does the actual writing task. */ private IndexWriter writer; /* * Thread which makes writing asynchronous */ private Thread writerThread; /* * We need to set this to false if the document addition is completed. This * will not immediately stop the writing as there could be some documents in * the queue. It completes once all documents are written and the queue is * empty. */ private boolean keepRunning = true; /* * This flag is set to false once writer is done with the queue data * writing. */ private boolean isRunning = true; /* * Duration in miliseconds for which the writer should sleep when it finds * the queue empty and job is still not completed */ private long sleepMilisecondOnEmpty = 100; /** * This method should be used to add documents to index queue. If the queue * is full it will wait for the queue to be available. * * @param doc * @throws InterruptedException */ public void addDocument(Document doc) throws InterruptedException documents.put(doc); public void startWriting() writerThread = new Thread(this, "AsynchronousIndexWriter"); writerThread.start(); /** * Constructor with indexwriter as input. It Uses ArrayBlockingQueue with * size 100 and sleepMilisecondOnEmpty is 100ms * * @param w */ public AsynchronousIndexWriter(IndexWriter w) this(w, 100, 100); /** * Constructor with indexwriter and queue size as input. It Uses * ArrayBlockingQueue with size queueSize and sleepMilisecondOnEmpty is * 100ms * * @param w * @param queueSize */ public AsynchronousIndexWriter(IndexWriter w, int queueSize) this(w, queueSize, 100); /** * Constructor with indexwriter, queueSize as input. It Uses * ArrayBlockingQueue with size queueSize * * @param w * @param queueSize * @param sleepMilisecondOnEmpty */ public AsynchronousIndexWriter(IndexWriter w, int queueSize, long sleepMilisecondOnEmpty) this(w, new ArrayBlockingQueue(queueSize), sleepMilisecondOnEmpty); /** * A implementation of BlockingQueue can be used * * @param w * @param queueSize * @param sleepMilisecondOnEmpty */ public AsynchronousIndexWriter(IndexWriter w, BlockingQueue queue,

long sleepMilisecondOnEmpty) writer = w; documents = queue; this.sleepMilisecondOnEmpty = sleepMilisecondOnEmpty; startWriting(); /* * (non-Javadoc) * * @see java.lang.Runnable#run() */ public void run() while (keepRunning /** * Stop the thread gracefully, wait until its done writing. */ private void stopWriting() this.keepRunning = false; try while (isRunning) //using the same sleep duration as writer uses Thread.sleep(sleepMilisecondOnEmpty); catch (InterruptedException e) e.printStackTrace(); public void optimize() throws CorruptIndexException, IOException writer.optimize(); public void close() throws CorruptIndexException, IOException stopWriting(); writer.close(); Below is a sample class which demonstrates how we can use this class. Here are few things to note, asynchronous thread is started as soon as you instantiate using new AsynchronousIndexWriter(...) TestAsyncWriter.java package swiki.lucene.asynchronous; import org.apache.lucene.analysis.standard.StandardAnalyzer; import org.apache.lucene.document.Document; import org.apache.lucene.document.Field; import org.apache.lucene.index.IndexWriter; import org.apache.lucene.store.Directory; import org.apache.lucene.store.FSDirectory; /** * @author swiki swiki * */ public class TestAsyncWriter public static void main(String[] args) try Directory fsdir = FSDirectory.getDirectory("index"); IndexWriter w = new IndexWriter(fsdir, new StandardAnalyzer(), true); AsynchronousIndexWriter writer = new AsynchronousIndexWriter(w); /* * This call can be replaced by the logic of reading * data using multiple threads */ addDocumentsInMultipleThreads(writer); writer.optimize(); writer.close(); catch (Exception e) e.printStackTrace(); private static void addDocumentsInMultipleThreads( AsynchronousIndexWriter writer) throws InterruptedException //add here the code for adding document from multiple threads. Document doc = new Document(); doc.add(new Field("content","My Content", Field.Store.YES, Field.Index.UN_TOKENIZED)); writer.addDocument(new Document()); If you find this useful or have some suggestions for improvements please leave a comment and I will try to respond.

How to choose the right technology for your App?

Do you need to develop a mobile application? Don't know whether to choose native or hybrid technology? Is the price the only difference or are there more aspects to consider?

It may seem like a simple decision, but it is not exactly like that. The software development services you choose will define many things about your final application, and will have a direct impact on your users' experience. And at this point, you cannot fail.

To be native or to be hybrid: that is the question

There is an ongoing debate surrounding mobile app development. When choosing, this is our first recommendation, always focus on your users and give them the best experience. Nobody has time for bad experiences. The success of your application depends on this.

So, let's talk in detail about native and hybrids . Are you ready?

Advantages and disadvantages of native applications

Native mobile technology refers to the creation of applications suitable to run on specific mobile operating systems. The most common native programming languages ​​are Objective-C or Swift for iOS and Java or Kotlin for Android.

These are the advantages of choosing native technology:

Advantages of native mobile applications

– Greater performance and speed: they are faster than hybrid applications.

– The use of mobile phone hardware is more efficient because it is accessed and used through the device's native functions of the selected operating system.

– Intuitive to use: These apps tend to have a consistent look and feel with most other native apps on the device. Therefore, users find them easier to navigate and use.

– More security: your levels of control and authorization over API calls to and from the server are better.

– Responsive, high-performance applications.

– They can interact with native libraries.

– They work offline: you can use them even if you are not connected (it happens often, believe me).

– Better user experience: due to all the previous advantages and, in addition, because they quickly access and use the integrated capabilities of the user's device such as the calendar, camera or GPS.

– Testing for developers is simpler: you can test more thoroughly.

– They have access to all the advanced functions of native devices.

– Its better distribution in application stores improves its discoverability.

But of course it also has some cons:

Disadvantages of native mobile applications

– Its development is expensive.

– They only work on one platform.

– They require more resources from the developer.

– Less code reuse.

– Its development takes a lot of time.

– Require frequent updates.

– They must be recorded into a different language to port them to a diverse ecosystem of devices.

– Your upfront expenses are more expensive compared to hybrid applications.

– They are not the best option when developing simple applications.

Advantages and disadvantages of hybrid applications

Now it's time to talk about hybrid technology.  Mix of native apps and web apps is hybrid app. Therefore, many mistakenly describe them as websites packaged in a native wrapper.

Languages ​​like JavaScript, HTML5, and CSS are used for hybrid app development and hybrid app framework such as Flutter, React Native, Ionic, Xamarin, or Cordova re used

Let's see them.

Let's start on the positive side and talk about the advantages of this technology.

Advantages of hybrid mobile applications

– Achieve greater developer productivity thanks to cross-platform compatibility.

– They reduce development costs because they are easier to build, require less development time, and only require one code base for multiple platforms.

– They do not need a web browser like web applications.

– They have access to internal APIs and device hardware.

– need a single code base for multiple platforms.

– They reach a broader audience through various platforms.

– Easy to launch and update.

On the other hand, we have the disadvantages:

Cons of Hybrid Mobile Apps

– The user experience is never as good as that of a native app.

– Lower performance.

– Lower speed.

– Less flexibility.

– More user interface design time.

– Limited tools.

– Test complexity: This is because they share a lot of code between platforms and some of that code is often native to take advantage of the underlying hardware.

– They depend on a third-party platform to deploy the application wrapper.

– They are not convenient when more customization is needed. In this case, native apps are more efficient when it comes to reducing costs.

4 tips for selecting the right technology for your application

Product lifespan: If you plan to develop a long-term mobile application (for example, mobile banking), native development frameworks and tools are more stable.

Performance and user experience: This should be one of your top priorities. Regardless of the custom software development services you choose, your users' experience must be excellent because it is the key to the success of an application. According to this, native applications ensure the best user experience, but require more development time. On the contrary, the user experience of hybrid applications is less, but the development time is shorter than that of native ones.

Access to hardware resources: Native technology is the option when the application requires complete access to all the resources and services of the target device. If not, hybrid technology is also a good option.

UI/UX Design: (In general) native apps offer more impressive visuals and exceptional UX, but hybrid apps can also do a good job.
