Highlights from the 2025 Stack Overflow Developer Survey

-

Introduction

The 15th Annual Stack Overflow Developer Survey is now out. With over 49,000 responses from 177 countries, the 2025 findings offer a rich view into how developers work—and how they feel—amid rising AI adoption (survey.stackoverflow.co, survey.stackoverflow.co).



Dev & AI Trends at a Glance

Widespread AI Adoption Coupled with Waning Trust

  • A whopping 84% of developers now use—or plan to use—AI tools in their workflows, up from 76% last year (survey.stackoverflow.co).
  • Yet trust in AI is falling dramatically: 46% say they do not trust AI output, compared to just 31% in 2024 (itpro.com).
  • Positive sentiment toward AI tools dropped from over 70% to roughly 60% this year (survey.stackoverflow.co).
  • The top frustration? Developers cite “AI solutions that are almost right, but not quite” as a pain point—leading to increased time spent debugging (survey.stackoverflow.co).
  • Because of this, 75% would still prefer asking another person when they doubt an AI-generated answer (stackoverflow.blog).

AI Agents Boost Efficiency—But Not Everyone’s Onboard

  • While 69% of users agree AI agents have ramped up their productivity, agentic AI isn’t widespread yet (survey.stackoverflow.co).
  • Only 31% use AI agents daily, 17% plan to adopt them, and over one-third say they don’t plan to at all (itpro.com).

Tech Trends & Language Popularity

Python’s Popularity Surges

  • Python saw a 7-point increase in adoption from 2024, underscoring its appeal across AI, data science, and backend development (survey.stackoverflow.co).
  • Other widely used languages include JavaScript (66%), HTML/CSS (62%), SQL (59%), Bash/Shell (49%), and TypeScript (44%) (survey.stackoverflow.co).

IDEs Remain Consistent: VSCode Rules

  • For the fourth straight year, Visual Studio Code maintains a dominant spot among developer environments, followed by Visual Studio, Notepad++, IntelliJ, and Vim (survey.stackoverflow.co).

Work & Community Insights

Employment Snapshot

  • Approximately 70% of respondents are employed. In countries like Germany and the UK, employment rates are slightly higher—76% and 75%, respectively (survey.stackoverflow.co).

Community Still Matters—Maybe More So

  • In an age of AI-generated code, human-curated knowledge platforms remain key: 84% rely on Stack Overflow, 67% on GitHub, and 61% on YouTube for support and learning (stackoverflow.blog).
  • This reinforces Stack Overflow’s role as a trusted, human-verified source of truth (stackoverflow.blog).

Summary Table

ThemeKey Insight
AI Adoption84% of developers use or plan to use AI tools
Trust Issues46% don’t trust AI output; debugging “almost-right” code is a major pain
Agent Productivity69% report increased efficiency with AI agents, but wider adoption remains modest
Python’s RisePython grew by 7 percentage points in usage
IDE PreferencesVS Code remains the most popular; Visual Studio, IntelliJ, Notepad++, and Vim follow
Developer SupportHuman platforms (Stack Overflow, GitHub, YouTube) retain strong relevance

Final Thoughts

The 2025 results paint a complex landscape: developers are integrating AI into their workflows more than ever—yet skepticism and caution are on the rise. Debugging imperfect AI output, difficulty trusting automated solutions, and the enduring importance of human-verified platforms all suggest that trust still trumps convenience.

Moreover, Python’s growing popularity and VS Code’s dominance remind us that while tools evolve, certain standards and tools remain steadfast.

Mount StorageBox to the server for backup

-
  Quickly  solution Install cifs-utils: apt-get install cifs-utils Adjust and add the following lines to   crontab -e   : # reboot # This one should be moved to /etc/fstab @reboot /sbin/mount.cifs -o user=uXXXXXXXX,pass=xxxxxXXXXXX//uXXXXXX.your-storagebox.be/backup /mnt/storagebox_jobsites_backup/ SAMBA/CIFS You can mount your Storage Box via Samba/CIFS. You can use the following UNC path. If you are using your main account, the share name is  backup . If you are using a sub-account, you must use the username of the sub-account as the username and share name. Linux/Unix: //<username>.your-storagebox.de/<share_name> Windows \\<username>.your-storagebox.de\<share_name> If you use a FritzBox Router from AVM, you need to deactivate the NetBIOS filter for Samba/CIFS to work. Please check the AVM knowledge base for more information.  https://en.avm.de/service/knowledge-base/dok/FRITZ-Box-7590/835_Shared-files-and-printers-o...

psql: error: connection to server at "localhost" (127.0.0.1), port 5433 failed: ERROR: failed to authenticate with backend using SCRAM DETAIL: valid password not found

ERROR psql: error: connection to server at "localhost" (127.0.0.1), port 5433 failed: ERROR: failed to authenticate with backend using SCRAM DETAIL: valid password not found Since Pgpool-II is a PostgreSQL proxy that works between clients and PostgreSQL servers, the authentication comprises two steps: Authentication between client and Pgpool-II Authentication between Pgpool-II and PostgreSQL servers Starting with Pgpool-II 4.0, Pgpool-II supports scram-sha-256 authentication. scram-sha-256 authentication method is strongly recommended because it is the most secure password-based authentication method. Solution 1 If PostgreSQL servers require  MD5  or  SCRAM  authentication for some user’s authentication but the password for that user is not present in  pool_passwd , then enabling  allow_clear_text_frontend_auth  will allow the  Pgpool-II  to use clear-text-password authentication with user to get the password in plain text form from the user ...

Keeping Your SSH Connections Alive: Configuring ServerAliveInterval and ServerAliveCountMax

-
Image
Maintaining a stable SSH connection is essential when working on remote servers. Disconnections due to inactivity can interrupt workflows and be quite frustrating. Fortunately, you can configure SSH to send periodic keep-alive messages, preventing your connection from timing out. Step-by-Step Guide 1. Open the SSH Client Configuration File Use your preferred text editor to modify the SSH configuration file. For example, with  vim : sudo vim /etc/ssh/ssh_config If OpenSSH is installed via Homebrew, the configuration file might be located at: /usr/ local /etc/ssh/ssh_config 2. Modify the Configuration Add the following lines after the  Host *  directive to apply these settings to all SSH connections: ServerAliveInterval 240 ServerAliveCountMax 10 ServerAliveInterval : Specifies the interval (in seconds) at which the client sends keep-alive messages to the server. In this case, every 240 seconds. ServerAliveCountMax : Limits the number of keep-alive messages sent w...
