JetBrains released an AI-powered version of ReSharper, its developer productivity extension for Microsoft Visual Studio. The new version, ReSharper 2023.2, is the first that will come with AI-powered development assistance.
The Early Access Program version includes a preview version of the AI assistant, a chat intended for programming questions. .NET developers using Visual Studio and ReSharper can use the AI assistant to troubleshoot or refactor existing code, generate code snippets or documentation and ask general questions about programming.
To access the AI-powered features users must log into JetBrains AI Services to enable the AI Assistant. When developers use AI features, some contextual information, such as file types, language, and framework used is shared with the provider of the large language model (LLM). The assistant does not have access to the source code unless developers include code fragments in their prompts. JetBrains also plans to support local and on-premises models so no data will be sent to the cloud-based LLM providers but the feature set will be rather limited.
The assistant takes into account the language and technologies of the projects and generates properly formatted code snippets. Users can copy and paste the generated code themselves or have the chatbot insert the code in the editor. The assistant also includes several prompts to get started.
Below is an example of what the assistant generates when prompted with “How do I find an element in a sorted array?” one of the prompts included in the assistant:
If developers use source code in the prompts, the source code will be sent to the LLM provider and the AI model will be able to generate, explain, or document code. For example, when asked, “How can I read the values from this query?” with the following code:
var connection = new SqliteConnection("DataSource=:memory:");
var command = connection.CreateCommand();
command.CommandText = "Select * from Item where value > ?";
command.Parameters.Add(4);
var reader = command.ExecuteReader();
The AI assistant generates code to consume the reader and explains how it works:
To read the values from the query, you can use the SqliteDataReader
object that ExecuteReader() returns.
Here's an example of how you can do this:
while (reader.Read())
{
for (int i = 0; i < reader.FieldCount; i++)
{
Console.WriteLine($"{reader.GetName(i)}: {reader.GetValue(i)}");
}
}
This code will loop through each row that the query returns. For each row, it will loop through each field and print the field’s name and value.
The assistant also spotted that in the initial code fragment, connection, command and reader are not released, so it refactored the code to make sure they are properly cleaned up:
Please note that you should open the connection before executing
the command and close it after you're done.
Here's the complete code:
using (var connection = new SqliteConnection("DataSource=:memory:"))
{
connection.Open();
using (var command = connection.CreateCommand())
{
command.CommandText = "Select * from Item where value > ?";
command.Parameters.AddWithValue("value", 4);
using (var reader = command.ExecuteReader())
{
while (reader.Read())
{
for (int i = 0; i < reader.FieldCount; i++)
{
Console.WriteLine($"{reader.GetName(i)}: {reader.GetValue(i)}");
}
}
}
}
}
This code uses using statements to ensure that the SqliteConnection, SqliteCommand, and SqliteDataReader objects are correctly disposed of after use.
ReSharper also supports revisioning the prompts: if the original query needs revising or further information, developers can edit it instead of retyping the whole request. This will create a new chat with the assistant while preserving the original chat too. Furthermore, developers can organize the chats by creating, duplicating, renaming or deleting them.
The .NET community received the announcement with mixed feelings. Sébastien Lachance, a former Microsoft MVP said:
Usually, I don’t install beta version but when I saw AI Assistant in ReSharper, I could not resist. My first try was a success! My beloved tool ReSharper gets dramatically better.
Frans Bouma, creator and lead developer of a popular ORM for .NET, LLBLGen Pro, was disappointed:
Ugh, not you too… Come on! Invest in making the dev write *better* code instead of suggesting boiler plate goo that they won’t check if it’s wrong or not, resulting in crappy code that might succeed the tests but chances are these are generated by the goo generator too…
JetBrains AI assistant shares many commonalities with other AI-powered tools such as GitHub Copilot and Amazon CodeWhisperer but also adds unique features including chat history and accessing the assistant with ALT+Enter, the shortcut for everything.
The AI features are currently limited by the number of users and to the countries where OpenAI service is available. The AI service is free as part of the EAP program and the pricing information will be announced later. Apart from ReSharper, AI-powered assistant will be available in Rider as well as ReSharper for C++.
The release also introduced new quick-fixes and inspections for working with discard variables and inlay hints for LINQ queries. When debugging LINQ queries, developers will now see the intermediate output at each step of the query as inlay hints.

Property-based testing is an approach that involves specifying statements that should always be true, rather than relying on specific examples. It enables you to test functions across a large number of inputs with fewer tests.
Lucy Mair spoke about property-based testing at NDC Oslo 2023.
Property-based testing is a technique where one identifies properties – statements of the form “for all inputs that satisfy some precondition, some predicate holds” – and writes their tests using those, as Mair explained:
First, you write a function that specifies your property; it takes inputs that satisfy the precondition, then asserts the predicate holds. Next, you use a property-based testing framework which will generate many different inputs and run your function to check the predicate holds.
Mair presented examples using FsCheck and F#, but this technique can be used for any language, they said.
The most immediate benefit to writing property-based tests is being able to test functions across a large number of inputs without having to write a large number of tests, Mair said. Every run of a property-based test will use different inputs, which can give you confidence your code works in a general case. Mair mentioned that this is particularly valuable in finding edge cases for inputs you may never have thought to test.
Property-based tests work by generating and testing many cases so will take longer than traditional unit tests. The performance implications will vary based on your particular use case, Mair mentioned.
InfoQ interviewed Lucy Mair about property-based testing.
InfoQ: Can you give an example of a property?
Lucy Mair: Properties are related to functions, so let’s consider the case of a function concat(a, b) that concatenates two lists. As an example, concat([0, 1, 2], [3, 4]) = [0, 1, 2, 3, 4]
What statements can we write about c = concat(a, b) that are always true?
- The length of c will be a.length + b.length.
- All items within a will be present in c.
- All items within b will be present in c.
- Concatenating with an empty list returns the same list a = concat(a, []) = concat([], a).
InfoQ: How can we do property-based testing in front-end development?
Mair: Front-end development in JavaScript presents some unique challenges on the property-based testing front.
One issue is that JavaScript’s relatively lax runtime typing means generating an object of the correct shape for running the tests is non-trivial. TypeScript doesn’t help us here either; TypeScript types are compile-time only so cannot be used to create correctly shaped objects.
The second issue is that rendering components for front-end tests is slow, particularly if the test involves simulating user interactions. If your property-based tests include rendering they are likely to be unusably slow.
InfoQ: What are the potential downsides to property-based testing?
Mair: For property-based tests on pure functions, a traditional unit test may take e.g. 10 ms, and a property-based test may take e.g. 200 ms, so the performance impact is negligible. However, if your test is doing “slow” things, such as rendering a component, making API calls, or performing compute-intensive tasks then property-based tests may have too much of a performance overhead to use.
Introducing property-based tests to an existing code base may be a challenge. You are likely to have edge cases that may never arise during the running of the program and as such are never tested. An example of this is dividing by a number – zero is an invalid number in this case but you may know the number to never be non-zero due. This represents a specification that should be codified in tests but rarely is in practice.

(Reuters) – AI startup Nomic has raised $17 million in a new funding round from investors led by Coatue, the companies told Reuters.
The investment valued New York-based Nomic AI, a team of four at the time, at $100 million, showing continued interest from VCs to bet on small teams building popular AI products. Contrary Capital and Betaworks Ventures also participated in the round.
Founded in 2022, Nomic has released two products to date, including an open-source AI model, GPT4ALL, which is free to download and could run on devices such as a laptop. It also has a tool called Atlas that allows users to visualize unstructured datasets used to build large language models (LLM).
Nomic said its goal is to boost the visibility of datasets in model training, and democratize access to AI models.
“We want to allow people to have access to the most powerful models that are specialized for the use cases they care about, and to build those systems themselves. They need to be able to understand what data goes into those systems,” said Andriy Mulyar, co-founder at Nomic AI, who plans to use the funding for hiring and product development.
Nomic said its products have been used by over 50,000 developers from companies including Hugging Face. It also has partnerships with MongoDB and Replit.
Open-source models are seen as alternatives to proprietary models developed by AI labs such as OpenAI and Google, as researchers around the world collaborate to develop models that could rival GPT-4.
“It gives you the platform for privacy with a local model, which will become more important as people have unique data that they want to interact with LLM,” said Sri Viswanath, partner at Coatue.
Coatue has made a series investment in open-source AI startups, including Stability AI, Hugging Face and Replit.

Recently AWS announced the preview release of the AWS .NET Distributed Cache Provider for DynamoDB. This library enables Amazon DynamoDB to be used as the storage for ASP.NET Core’s distributed cache framework.
The AWS .NET Distributed Cache Provider for DynamoDB is the successor to the AWS DynamoDB Session State Provider, offering compatibility with both .NET Framework and ASP.NET Core applications. While the session state provider library, released in 2012, is limited to .NET Framework applications, the new distributed cache provider also extends its functionality to support ASP.NET Core.
Alex Shovlin, software development engineer at AWS, explains in an AWS Developer Tools blog post the benefit of caching:
A cache can improve the performance of an application; an external cache allows the data to be shared across application servers and helps to avoid cache misses when the application is restarted or redeployed.
To use the library, developers can install the AWS.AspNetCore.DistributedCacheProvider package from NuGet.org. For instance, when they are building an application that requires sessions in a distributed webapp, .NET’s session state middleware looks for an implementation of IDistributedCache to store the session data. They can accomplish that by directing the session service to use the DynamoDB distributed cache implementation through dependency injection.
The company recommends configuring the cache provider with the following options for production applications:
- A Tablename, the name of the DynamoDB table that will store the cache data
- A PartitionKeyName, the name of the DynamoDB table’s partition key
- A TTLAttributeName, a DynamoDB’s Time To Live (TTL) feature, which removes cache items from the table
var builder = WebApplication.CreateBuilder(args);
builder.Services.AddAWSDynamoDBDistributedCache(options =>
{
options.TableName = "session_cache_table";
options.PartitionKeyName = "id";
options.TTLAttributeName = "cache_ttl";
});
builder.Services.AddSession(options =>
{
options.IdleTimeout = TimeSpan.FromSeconds(90);
options.Cookie.IsEssential = true;
});
var app = builder.Build();
...
In addition, Shovlin points out in the blog post that:
- The partition key must be of a type string without a sort key required for the table to prevent exceptions during cache operations
- Enable DynamoDB’s Time to Live feature for the table to ensure expired cached entries are automatically deleted
- Prefix the partition keys of cached items with a configurable value (default prefix is “dc:”) to avoid collisions and enable fine-grained access control using IAM policy conditions
- Additionally, consider using CreateTableIfNotExists for development or testing purposes, as it allows automatic table creation but may add latency to the first cache operation
Azure Cosmos DB, a comparable managed service like DynamoDB on Azure, can also serve as a cache for the session state. A Microsoft Caching Extension using Azure Cosmos DB package contains an implementation of IDistributedCache. This package can be leveraged in ASP.NET Core as a Session State Provider.
Alternatively, developers can use Amazon Relational Database Service (Amazon RDS) for SQL Server and Amazon ElastiCache for Redis for caching regarding ASP.NET Core applications. Both have an implementation of IDistributedCache: Microsoft.Extensions.Caching.SqlServer and Microsoft.Extensions.Caching.StackExchangeRedis.
The authors of a Microsoft Workloads on AWS blog post last year concluded:
AWS provides several managed services that can serve as a managed cache for your ASP.NET Core web applications. We examined how Amazon RDS for SQL Server and Amazon ElastiCache for Redis can be used as a distributed cache layer for your applications. They are managed services that are simple to set up and scale, with low operational overhead.
With AWS .NET Distributed Cache Provider for DynamoDB library, there is an additional now with Amazon DynamoDB.
The Microsoft documentation shows more details on using an IDistributedCache implementation to save session state data. In addition, the .NET on AWS page provides information on learning about building, deploying, and developing .NET applications on AWS.

Database administrators have a tough job. They’re expected to create foundational, secure systems that support an entire organization’s data efforts—but unless something goes wrong with a database migration or the system is hit with unexpected downtime (to name just two problems these specialists are expected to solve), their efforts are often unrecognized by their colleagues.
Nonetheless, from a pure tech perspective, database administration is a rewarding career with many interesting problems to solve, along with enough dynamism to keep anyone happy long-term. To find out what skills truly make a great database administrator, we spoke to several experts with deep experience in the field.
What does a database administrator do day-to-day?
A database administrator leads the design, implementation, maintenance, and security implementation of a database. Database admins work closely with software developers, system administrators, and IT staff to ensure that databases are functioning properly, and the data within is accessible to users, not corrupted, and, most of all, secure from outside agencies.
What skills do database administrators need?
Database administrators must have a strong understanding of database theory and the technologies used to build and implement them. They also need to be able to work with a variety of database software products as required by their employer, and they need to be able to communicate effectively with other technical staff and with users of the database.
How much does a database administrator make?
According to the latest Dice Tech Salary Report, the average database administrator makes $107,828 per year, a year-over-year decline of 3.2 percent. Despite that decline, the job remains very much in demand; organizations everywhere need their databases spun up and maintained. Those database administrators with considerable experience can easily earn far more, especially if they have the specialized knowledge necessary for certain industries such as healthcare.
What platforms should database administrator master?
“There are several key ones to consider,” says Ivan Novak, Head of IT and Energy Casino. “First and foremost is Oracle, as it remains one of the leading database management systems in the industry. Its widespread use and features make it a valuable skill to possess. Another platform worth mastering is Microsoft SQL Server. With its popularity in many organizations, having expertise in SQL Server can open up numerous opportunities for database administrators.
Novak adds: “MySQL is an open-source database that is widely used for web applications. Gaining proficiency in MySQL can be advantageous as it provides flexibility and scalability. As NoSQL databases gain popularity, mastering MongoDB can also be beneficial. MongoDB’s document-oriented approach and ability to handle large amounts of data make it a valuable platform to understand. Lastly, PostgreSQL, known for its reliability, is another platform worth considering as it offers powerful features for database administration.”
Ruchi Agarwal, senior software engineer at Netflix and former software engineer at Apple, gives us her full list:
Oracle Database: Oracle is one of the most widely used enterprise-level database management systems (DBMS) and offers comprehensive tools and features for managing large-scale databases. Mastering Oracle Database administration, including tasks such as installation, configuration, performance tuning, backup and recovery, and security management, is highly valuable in many organizations.
Microsoft SQL Server: Microsoft SQL Server is another popular DBMS used in many organizations, particularly those using Microsoft technologies. Becoming proficient in SQL Server administration, including tasks such as installation, configuration, database design, query optimization, and high availability, can open up numerous job opportunities.
MySQL: MySQL is an open-source relational database management system commonly used in web applications and small to medium-sized enterprises. Understanding MySQL administration, including installation, configuration, performance tuning, and backup and recovery, can be beneficial, especially in environments that heavily rely on web-based applications.
PostgreSQL: PostgreSQL is a powerful open-source object-relational database system known for its robustness, extensibility, and support for advanced features. Mastering PostgreSQL administration, including tasks such as installation, configuration, performance optimization, replication, and security management, can provide you with in-demand skills for handling diverse database requirements.
MongoDB (optional): While the first four platforms mentioned are relational databases, it’s worth considering adding a NoSQL database like MongoDB to your skill set. MongoDB is a document-oriented database that offers flexibility, scalability, and high-performance for handling unstructured and semi-structured data. It is widely used in modern web and mobile applications. Having expertise in both SQL and NoSQL databases can be beneficial for a DBA’s career.
What technical skills do database administrators need?
Here is Agarwal’s list for technical skills, too:
- Database Management Systems (DBMS): DBAs should have a deep understanding of one or more DBMS platforms such as Oracle, Microsoft SQL Server, MySQL, PostgreSQL, or MongoDB. They should be proficient in tasks such as installation, configuration, maintenance, and troubleshooting of these systems.
- Database Design and Modeling: DBAs should possess strong skills in database design and data modeling. This includes creating efficient database schemas, defining relationships between tables, ensuring data integrity, and optimizing database structures for performance.
- SQL (Structured Query Language): SQL is the standard language used for interacting with relational databases. DBAs need to be well-versed in SQL to perform tasks like querying, updating, and managing databases. They should have expertise in writing complex SQL queries, optimizing SQL code, and understanding database optimization techniques.
- Performance Tuning and Optimization: DBAs should be proficient in monitoring and optimizing database performance. This includes identifying and resolving performance bottlenecks, optimizing SQL queries, configuring database parameters, implementing indexing strategies, and analyzing database statistics.
- Backup and Recovery: DBAs need to have a solid understanding of backup and recovery strategies to ensure the availability and integrity of data. This includes creating backup plans, scheduling backups, testing restore processes, and implementing disaster recovery plans.
- Security and Access Control: DBAs must have expertise in database security to protect sensitive data and ensure compliance with regulations. They should be skilled in implementing access control mechanisms, setting up user roles and permissions, encrypting data, and monitoring for security threats.
What soft skills are necessary for database administrators?
Vladislav Bilay, cloud DevOps engineer with Aquiva Labs, tells Dice: “In addition to technical expertise, database admins should know attention to detail is necessary for maintaining data accuracy and integrity. Additionally, time management and organizational skills help in prioritizing tasks and meeting deadlines. Communication skills are essential to interact with stakeholders, understand user requirements, and convey complex concepts in a clear manner. Problem-solving skills enable administrators to analyze issues and devise solutions efficiently.”
Novak agrees that communication is an essential soft skill for any database administrator: “Effective communication is essential for understanding user needs and collaborating with colleagues… As a one-person army, tackling complex problems and finding efficient solutions is crucial. The IT landscape is ever-evolving, so being adaptable and open to learning new technologies is essential. Attention to detail is also important as database administrators must ensure data integrity and security. Finally, collaborating with other IT professionals and working in a team environment is essential for larger projects.”
Can you get a job as a database administrator without a degree?
Given the demand for all kinds of tech specialists at the moment, recruiters and hiring managers are more willing than ever to hire database administrators and other tech pros who don’t necessarily have a formal degree—but you’ll need to demonstrate that you have the skills and experience to succeed in the role. No matter what your background, prepare for an in-depth technical interview that will require you to offer up solutions to hypothetical problems and show your knowledge of various tools and databases.
“While having a degree in a related field such as computer science or information technology can be advantageous, it is possible to get a job as a database administrator without a degree,” says Novak. “Employers often prioritize practical experience and relevant certifications. Building a strong portfolio of projects, acquiring certifications, and gaining hands-on experience through internships or entry-level positions can help compensate for the lack of a degree. Demonstrating technical competence, continuous learning, and a passion for the field can make you a competitive candidate even without a formal degree.”
“Yes, it is possible to get a job as a database administrator (DBA) without a degree,” Agarwal adds. “While many employers may prefer candidates with a degree in computer science, information technology, or a related field, the field of database administration also values practical experience, certifications, and relevant skills.” When trying to stand out in a crowded field of applicants, possessing certifications can help you stand out.
