JetBrains Fleet dropped for AI products instead
https://www.reddit.com/r/programming/comments/1pnz3n0/jetbrains_fleet_dropped_for_ai_products_instead/

<!-- SC_OFF -->JetBrains Fleet was going to be an alternative to VS Code and seemed quite promising. After over 3 years of development since the first public preview release, it’s now dropped in order to make room for AI (Agentic) products. – “Starting December 22, 2025, Fleet will no longer be available for download. We are now building a new product focused on agentic development” At the very least, they’re considering open sourcing it, but it’s not definite. A comment from the author of the article (https://blog.jetbrains.com/fleet/2025/12/the-future-of-fleet/#remark42__comment-f3d6d88b-f10d-4f0a-9579-a6b940314b01) regarding open sourcing Fleet: – “It’s something we’re considering but we don’t have immediate plans for that at the moment.” <!-- SC_ON --> submitted by /u/markmanam (https://www.reddit.com/user/markmanam)

"If you time-traveled to 1979 and found yourself sitting across from me in my office at Bell Labs—just as I was drafting the initial designs for what would become 'C with Classes'—what would you tell me?": A homework by Bjarne Stroustrup.
https://www.reddit.com/r/programming/comments/1po5nq5/if_you_timetraveled_to_1979_and_found_yourself/

<!-- SC_OFF -->This was a homework given by Bjarne Stroustrup when he was my professor at Texas A&M University in Spring Semester of 2013. The course, Generic Programming in C++, was one of the most fun classes I took at Texas A&M University. I'm posting it in my blog. https://coderschmoder.com/i-time-traveled-1979-met-bjarne-stroustrup
Take note that I updated the essay to reflect current C++ releases. My original essay was written when C++11 was released, and I mostly talked about RAII, and data type abstractions. Although I thought my essay was lacking in substance, he gave me a 95 :-D. So, I thought I update my essay and share it with you. When he gave the homework I think the context of the conversation was critics were ready for C++ to die because of lack of garbage collection or memory management, and the homework was akin to killing two birds with one stone(so to speak) - one, to see if we understand RAII and the life cycle of a C++ object, and two, how we see this "shortcomings" of C++. How about you? If you time-travel back to 1979, what would you tell him? <!-- SC_ON --> submitted by /u/CoderSchmoder (https://www.reddit.com/user/CoderSchmoder)

Sandboxing AI Agents: Practical Ways to Limit Autonomous Behavior
https://www.reddit.com/r/programming/comments/1po8ar9/sandboxing_ai_agents_practical_ways_to_limit/

<!-- SC_OFF -->I’ve been exploring how to safely deploy autonomous AI agents without giving them too much freedom. In practice, the biggest risks come from: unrestricted tool access filesystem and network exposure agents looping or escalating actions unexpectedly I looked at different sandboxing approaches: containers (Docker, OCI) microVMs (Firecracker) user-mode kernels (gVisor) permission-based tool execution I wrote a deeper breakdown with concrete examples and trade-offs here : https://medium.com/@yessine.abdelmaksoud.03/sandboxing-for-ai-agents-2420ac69569e I’d really appreciate feedback from people working with agents in production. <!-- SC_ON --> submitted by /u/After_Customer251 (https://www.reddit.com/user/After_Customer251)

Building a Custom DatePicker in Java Swing and Persisting Dates in MySQL
https://www.reddit.com/r/programming/comments/1pooqzj/building_a_custom_datepicker_in_java_swing_and/

<!-- SC_OFF -->Java Swing doesn’t provide a modern DatePicker by default, so I built a custom calendar component in pure Swing and connected it to MySQL using JDBC. The calendar supports month/year navigation, date selection, and saving the selected date directly into a DATE column in MySQL. This is useful for forms like birth date, registration, or appointments. I shared a short video walkthrough and the full source code for anyone learning Java Swing or working on desktop projects. 📺 Video: Java Swing Custom Calendar DatePicker | Save Selected Date into MySQL Database (https://www.youtube.com/watch?v=pLI2I6TCiFw&t=426s)
