&lt;p&gt;&lt;strong&gt;Michael #2: &lt;a href="https://docs.djangoproject.com/en/dev/releases/6.0/?featured_on=pythonbytes"&gt;Django 6 is coming&lt;/a&gt;&lt;/strong&gt;&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;&lt;em&gt;Expected December 2025&lt;/em&gt;&lt;/li&gt;
&lt;li&gt;Django 6.0 supports Python 3.12, 3.13, and 3.14&lt;/li&gt;
&lt;li&gt;Built-in support for the &lt;a href="https://docs.djangoproject.com/en/6.0/topics/security/#security-csp"&gt;Content Security Policy (CSP)&lt;/a&gt; standard is now available, making it easier to protect web applications against content injection attacks such as cross-site scripting (XSS).&lt;/li&gt;
&lt;li&gt;The &lt;a href="https://docs.djangoproject.com/en/6.0/topics/templates/#template-language-intro"&gt;Django Template Language&lt;/a&gt; now supports &lt;a href="https://docs.djangoproject.com/en/6.0/ref/templates/language/#template-partials"&gt;template partials&lt;/a&gt;, making it easier to encapsulate and reuse small named fragments within a template file.&lt;/li&gt;
&lt;li&gt;Django now includes a built-in Tasks framework for running code outside the HTTP request–response cycle. This enables offloading work, such as sending emails or processing data, to background workers.&lt;/li&gt;
&lt;li&gt;Email handling in Django now uses Python’s modern email API, introduced in Python 3.6. This API, centered around the &lt;a href="https://docs.python.org/3/library/email.message.html#email.message.EmailMessage"&gt;&lt;strong&gt;&amp;lt;code&gt;email.message.EmailMessage&amp;lt;/code&gt;&lt;/strong&gt;&lt;/a&gt; class&lt;/li&gt;
&lt;/ul&gt;

&lt;ul&gt;
&lt;li&gt;get_args, TypeGuard, TypeIs, and more goodies&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;&lt;strong&gt;Michael #4: &lt;a href="https://github.com/codespell-project/codespell?featured_on=pythonbytes"&gt;codespell&lt;/a&gt;&lt;/strong&gt;&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;Learned from &lt;a href="https://github.com/mikeckennedy/talk-python-in-production-devops-book/pull/14?featured_on=pythonbytes"&gt;this PR for the Talk Python book&lt;/a&gt;.&lt;/li&gt;
&lt;li&gt;Fix common misspellings in text files.&lt;/li&gt;
&lt;li&gt;It's designed primarily for checking misspelled words in source code (backslash escapes are skipped), but it can be used with other files as well.&lt;/li&gt;
&lt;li&gt;It does not check for word membership in a complete dictionary, but instead looks for a set of common misspellings. Therefore it should catch errors like "adn", but it will not catch "adnasdfasdf".&lt;/li&gt;
&lt;li&gt;It shouldn't generate false-positives when you use a niche term it doesn't know about.&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;&lt;strong&gt;Extras&lt;/strong&gt;&lt;/p&gt;

&lt;/ul&gt;

&lt;p&gt;Michael:&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;Follow up on tach from Gerben Dekker:
&lt;ul&gt;
&lt;li&gt;&lt;strong&gt;&lt;code&gt;tach&lt;/code&gt; has been unmaintained for a bit but is not anymore&lt;/strong&gt;. It was the main product from Gauge which is a Y combinator startup that pivoted to something unrelated and abandoned &lt;code&gt;tach&lt;/code&gt;. However, https://github.com/DetachHead forked it but now got access to the main repo and has committed to maintaining it.&lt;/li&gt;
&lt;li&gt;&lt;code&gt;ruff analyze graph&lt;/code&gt; is fully independent of &lt;code&gt;tach&lt;/code&gt; - we actually started to look into alternatives for &lt;code&gt;tach&lt;/code&gt; when it became unmaintained and then found &lt;code&gt;ruff analyze graph&lt;/code&gt;.&lt;/li&gt;
&lt;li&gt;For our use case, with just a bit of manipulation on top of &lt;code&gt;ruff analyze graph&lt;/code&gt; we replaced our use of &lt;code&gt;deptry&lt;/code&gt; (which was slower - and I try to be careful depending on one-man projects).&lt;/li&gt;
&lt;/ul&gt;&lt;/li&gt;

&lt;p&gt;&lt;strong&gt;Michael #0&lt;/strong&gt;: &lt;a href="https://talkpython.fm/black-friday?featured_on=pythonbytes"&gt;Black Friday is on at Talk Python&lt;/a&gt;&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;What’s on offer:
&lt;ol&gt;
&lt;li&gt;An &lt;a href="https://training.talkpython.fm/courses/bundle/black-friday-ai-2025?featured_on=pythonbytes"&gt;AI course mini bundle&lt;/a&gt; (22% off)&lt;/li&gt;

&lt;li&gt;The new &lt;a href="https://mikeckennedy.gumroad.com/l/talk-python-in-production-book/black-friday-2025?featured_on=pythonbytes"&gt;Talk Python in Production book&lt;/a&gt; (25% off)&lt;/li&gt;
&lt;/ol&gt;&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;Brian: This is peer pressure in action&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;20% off &lt;a href="https://courses.pythontest.com/the-complete-pytest-course-bundle?featured_on=pythonbytes"&gt;The Complete pytest Course bundle&lt;/a&gt; (use code BLACKFRIDAY) through November
&lt;ul&gt;
&lt;li&gt;or use save50 for 50% off, your choice.&lt;/li&gt;
&lt;/ul&gt;&lt;/li&gt;
&lt;li&gt;&lt;a href="https://pragprog.com/titles/bopytest2/python-testing-with-pytest-second-edition/?featured_on=pythonbytes"&gt;Python Testing with pytest, 2nd edition&lt;/a&gt;, eBook (50% off with code save50) also through November
&lt;ul&gt;
&lt;li&gt;I would have picked 20%, but it’s a PragProg wide thing&lt;/li&gt;
&lt;/ul&gt;&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;&lt;strong&gt;Michael #1: &lt;a href="https://discuss.python.org/t/pep-814-add-frozendict-built-in-type/104854?featured_on=pythonbytes"&gt;PEP 814 – Add frozendict built-in type&lt;/a&gt;&lt;/strong&gt;&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;by Victor Stinner &amp;amp; Donghee Na&lt;/li&gt;
&lt;li&gt;A new public immutable type &lt;code&gt;frozendict&lt;/code&gt; is added to the &lt;code&gt;builtins&lt;/code&gt; module.&lt;/li&gt;
&lt;li&gt;We expect &lt;code&gt;frozendict&lt;/code&gt; to be safe by design, as it prevents any unintended modifications. This addition benefits not only CPython’s standard library, but also third-party maintainers who can take advantage of a reliable, immutable dictionary type.&lt;/li&gt;
&lt;li&gt;To add to &lt;a href="https://blobs.pythonbytes.fm/existing-frozen-typesstructures-in-python.html?cache_id=5788ae"&gt;existing frozen types in Python&lt;/a&gt;.&lt;/li&gt;

&lt;p&gt;&lt;strong&gt;Brian #2: From &lt;a href="https://squidfunk.github.io/mkdocs-material/?featured_on=pythonbytes"&gt;Material for MkDocs&lt;/a&gt;  to &lt;a href="https://zensical.org?featured_on=pythonbytes"&gt;Zensical&lt;/a&gt;&lt;/strong&gt;&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;Suggested by John Hagen&lt;/li&gt;
&lt;li&gt;A lot of people, me included, use Material for MkDocs as our MkDocs theme for both personal and professional projects, and in-house docs.&lt;/li&gt;
&lt;li&gt;This plugin for MkDocs is &lt;a href="https://github.com/squidfunk/mkdocs-material/issues/8523?featured_on=pythonbytes"&gt;now in maintenance mode&lt;/a&gt;&lt;/li&gt;
&lt;li&gt;The development team is switching to working on Zensical, a static site generator to overcome some technical limitations with MkDocs. There’s a series of posts about the transition and reasoning
&lt;ol&gt;
&lt;li&gt;&lt;a href="https://squidfunk.github.io/mkdocs-material/blog/2024/08/19/how-were-transforming-material-for-mkdocs/?featured_on=pythonbytes"&gt;Transforming Material for MkDocs&lt;/a&gt;&lt;/li&gt;

&lt;/ol&gt;&lt;/li&gt;
&lt;li&gt;Material for MkDocs
&lt;ul&gt;
&lt;li&gt;still around, but in maintenance mode&lt;/li&gt;
&lt;li&gt;all insider features now available to everyone&lt;/li&gt;
&lt;/ul&gt;&lt;/li&gt;
&lt;li&gt;Zensical is / will be
&lt;ul&gt;
&lt;li&gt;compatible with Material for Mkdocs, can natively read mkdocs.yml, to assist with the transition&lt;/li&gt;
&lt;li&gt;Open Source, MIT license&lt;/li&gt;
&lt;li&gt;funded by an offering for professional users: Zensical Spark&lt;/li&gt;

&lt;p&gt;&lt;strong&gt;Michael #3: &lt;a href="https://github.com/tach-org/tach?featured_on=pythonbytes"&gt;Tach&lt;/a&gt;&lt;/strong&gt;&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;Keep the streak: pip deps with uv + tach&lt;/li&gt;
&lt;li&gt;From Gerben Decker&lt;/li&gt;
&lt;li&gt;We needed some more control over linting our dependency structure, both internal and external.&lt;/li&gt;
&lt;li&gt;We use &lt;code&gt;tach&lt;/code&gt; (which you covered before IIRC), but also some home built linting rules for our specific structure. These are extremely easy to build using an underused feature of &lt;code&gt;ruff&lt;/code&gt;:  "uv run ruff analyze graph --python python_exe_path .".&lt;/li&gt;

&lt;p&gt;&lt;strong&gt;Brian #1: Possibility of a new website for Django&lt;/strong&gt;&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;Current Django site: &lt;a href="https://www.djangoproject.com?featured_on=pythonbytes"&gt;djangoproject.com&lt;/a&gt;&lt;/li&gt;
&lt;li&gt;Adam Hill’s in progress redesign idea: &lt;a href="https://django-homepage.adamghill.com?featured_on=pythonbytes"&gt;django-homepage.adamghill.com&lt;/a&gt;&lt;/li&gt;

&lt;/ul&gt;

&lt;p&gt;&lt;strong&gt;Michael #2: &lt;a href="https://github.com/slaily/aiosqlitepool?featured_on=pythonbytes"&gt;aiosqlitepool&lt;/a&gt;&lt;/strong&gt;&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;🛡️A resilient, high-performance asynchronous connection pool layer for SQLite, designed for efficient and scalable database operations.&lt;/li&gt;
&lt;li&gt;About 2x better than regular SQLite.&lt;/li&gt;
&lt;li&gt;Pairs with &lt;a href="https://github.com/omnilib/aiosqlite?featured_on=pythonbytes"&gt;aiosqlite&lt;/a&gt;&lt;/li&gt;
&lt;li&gt;&lt;code&gt;aiosqlitepool&lt;/code&gt; in three points:
&lt;ul&gt;
&lt;li&gt;&lt;strong&gt;Eliminates connection overhead&lt;/strong&gt;: It avoids repeated database connection setup (syscalls, memory allocation) and teardown (syscalls, deallocation) by reusing long-lived connections.&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;Faster queries via "hot" cache&lt;/strong&gt;: Long-lived connections keep SQLite's in-memory page cache "hot." This serves frequently requested data directly from memory, speeding up repetitive queries and reducing I/O operations.&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;Maximizes concurrent throughput&lt;/strong&gt;: Allows your application to process significantly more database queries per second under heavy load.&lt;/li&gt;
&lt;/ul&gt;&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;&lt;strong&gt;Brian #3: &lt;a href="https://deptry.com?featured_on=pythonbytes"&gt;deptry&lt;/a&gt;&lt;/strong&gt;&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;“deptry is a command line tool to check for issues with dependencies in a Python project, such as unused or missing dependencies. It supports projects using Poetry, pip, PDM, uv, and more generally any project supporting PEP 621 specification.”&lt;/li&gt;
&lt;li&gt;“Dependency issues are detected by scanning for imported modules within all Python files in a directory and its subdirectories, and comparing those to the dependencies listed in the project's requirements.”&lt;/li&gt;
&lt;li&gt;&lt;p&gt;Note if you use &lt;code&gt;project.optional-dependencies&lt;/code&gt;&lt;/p&gt;

&lt;div class="codehilite"&gt;
&lt;pre&gt;&lt;span&gt;&lt;/span&gt;&lt;code&gt;&lt;span class="k"&gt;[project.optional-dependencies]&lt;/span&gt;
&lt;span class="n"&gt;plot&lt;/span&gt;&lt;span class="w"&gt; &lt;/span&gt;&lt;span class="o"&gt;=&lt;/span&gt;&lt;span class="w"&gt; &lt;/span&gt;&lt;span class="p"&gt;[&lt;/span&gt;&lt;span class="s2"&gt;&amp;quot;matplotlib&amp;quot;&lt;/span&gt;&lt;span class="p"&gt;]&lt;/span&gt;
&lt;span class="n"&gt;test&lt;/span&gt;&lt;span class="w"&gt; &lt;/span&gt;&lt;span class="o"&gt;=&lt;/span&gt;&lt;span class="w"&gt; &lt;/span&gt;&lt;span class="p"&gt;[&lt;/span&gt;&lt;span class="s2"&gt;&amp;quot;pytest&amp;quot;&lt;/span&gt;&lt;span class="p"&gt;]&lt;/span&gt;
&lt;/code&gt;&lt;/pre&gt;
&lt;/div&gt;&lt;/li&gt;
&lt;li&gt;&lt;p&gt;you have to set a config setting to get it to work right:&lt;/p&gt;

&lt;div class="codehilite"&gt;
&lt;pre&gt;&lt;span&gt;&lt;/span&gt;&lt;code&gt;&lt;span class="k"&gt;[tool.deptry]&lt;/span&gt;
&lt;span class="n"&gt;pep621_dev_dependency_groups&lt;/span&gt;&lt;span class="w"&gt; &lt;/span&gt;&lt;span class="o"&gt;=&lt;/span&gt;&lt;span class="w"&gt; &lt;/span&gt;&lt;span class="p"&gt;[&lt;/span&gt;&lt;span class="s2"&gt;&amp;quot;test&amp;quot;&lt;/span&gt;&lt;span class="p"&gt;,&lt;/span&gt;&lt;span class="w"&gt; &lt;/span&gt;&lt;span class="s2"&gt;&amp;quot;docs&amp;quot;&lt;/span&gt;&lt;span class="p"&gt;]&lt;/span&gt;
&lt;/code&gt;&lt;/pre&gt;
&lt;/div&gt;&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;&lt;strong&gt;Michael #4: &lt;a href="https://github.com/juftin/browsr?featured_on=pythonbytes"&gt;browsr&lt;/a&gt;&lt;/strong&gt;&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;&lt;strong&gt;&lt;code&gt;browsr&lt;/code&gt;&lt;/strong&gt; 🗂️ is a pleasant &lt;strong&gt;file explorer&lt;/strong&gt; in your terminal. It's a command line &lt;strong&gt;TUI&lt;/strong&gt; (text-based user interface) application that empowers you to browse the contents of local and remote filesystems with your keyboard or mouse.&lt;/li&gt;
&lt;li&gt;You can quickly navigate through directories and peek at files whether they're hosted &lt;strong&gt;locally&lt;/strong&gt;, in &lt;strong&gt;GitHub&lt;/strong&gt;, over &lt;strong&gt;SSH&lt;/strong&gt;, in &lt;strong&gt;AWS S3&lt;/strong&gt;, &lt;strong&gt;Google Cloud Storage&lt;/strong&gt;, or &lt;strong&gt;Azure Blob Storage&lt;/strong&gt;.&lt;/li&gt;
&lt;li&gt;View code files with syntax highlighting, format JSON files, render images, convert data files to navigable datatables, and more.&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;&lt;strong&gt;Extras&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Michael #1: &lt;a href="https://github.com/ozeranskii/httptap?featured_on=pythonbytes"&gt;httptap&lt;/a&gt;&lt;/strong&gt;&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;Rich-powered CLI that breaks each HTTP request into DNS, connect, TLS, wait, and transfer phases with waterfall timelines, compact summaries, or metrics-only output.&lt;/li&gt;
&lt;li&gt;Features
&lt;ul&gt;
&lt;li&gt;&lt;strong&gt;Phase-by-phase timing&lt;/strong&gt; – precise measurements built from httpcore trace hooks (with sane fallbacks when metal-level data is unavailable).&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;All HTTP methods&lt;/strong&gt; – GET, POST, PUT, PATCH, DELETE, HEAD, OPTIONS with request body support.&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;Request body support&lt;/strong&gt; – send JSON, XML, or any data inline or from file with automatic Content-Type detection.&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;IPv4/IPv6 aware&lt;/strong&gt; – the resolver and TLS inspector report both the address and its family.&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;TLS insights&lt;/strong&gt; – certificate CN, expiry countdown, cipher suite, and protocol version are captured automatically.&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;Multiple output modes&lt;/strong&gt; – rich waterfall view, compact single-line summaries, or &lt;code&gt;-metrics-only&lt;/code&gt; for scripting.&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;JSON export&lt;/strong&gt; – persist full step data (including redirect chains) for later processing.&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;Extensible&lt;/strong&gt; – clean Protocol interfaces for DNS, TLS, timing, visualization, and export so you can plug in custom behavior.&lt;/li&gt;
&lt;/ul&gt;&lt;/li&gt;
&lt;li&gt;Example:&lt;/li&gt;

&lt;ul&gt;
&lt;li&gt;Dido Grigorov&lt;/li&gt;
&lt;li&gt;A few from the list
&lt;ul&gt;
&lt;li&gt;Use math functions instead of operators&lt;/li&gt;
&lt;li&gt;Avoid exception handling in hot loops&lt;/li&gt;
&lt;li&gt;Use itertools for combinatorial operations - huge speedup&lt;/li&gt;
&lt;li&gt;Use bisect for sorted list operations - huge speedup&lt;/li&gt;
&lt;/ul&gt;&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;&lt;strong&gt;Michael #3: &lt;a href="https://fastrtc.org?featured_on=pythonbytes"&gt;FastRTC&lt;/a&gt;&lt;/strong&gt;&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;The Real-Time Communication Library for Python: Turn any python function into a real-time audio and video stream over WebRTC or WebSockets.&lt;/li&gt;
&lt;li&gt;Features
&lt;ul&gt;
&lt;li&gt;🗣️ Automatic Voice Detection and Turn Taking built-in, only worry about the logic for responding to the user.&lt;/li&gt;
&lt;li&gt;💻 Automatic UI - Use the &lt;code&gt;.ui.launch()&lt;/code&gt; method to launch the webRTC-enabled built-in Gradio UI.&lt;/li&gt;
&lt;li&gt;🔌 Automatic WebRTC Support - Use the &lt;code&gt;.mount(app)&lt;/code&gt; method to mount the stream on a FastAPI app and get a webRTC endpoint for your own frontend!&lt;/li&gt;
&lt;li&gt;⚡️ Websocket Support - Use the &lt;code&gt;.mount(app)&lt;/code&gt; method to mount the stream on a FastAPI app and get a websocket endpoint for your own frontend!&lt;/li&gt;
&lt;li&gt;📞 Automatic Telephone Support - Use the &lt;code&gt;fastphone()&lt;/code&gt; method of the stream to launch the application and get a free temporary phone number!&lt;/li&gt;
&lt;li&gt;🤖 Completely customizable backend - A &lt;code&gt;Stream&lt;/code&gt; can easily be mounted on a FastAPI app so you can easily extend it to fit your production application. See the &lt;a href="https://huggingface.co/spaces/fastrtc/talk-to-claude?featured_on=pythonbytes"&gt;Talk To Claude&lt;/a&gt; demo for an example of how to serve a custom JS frontend.&lt;/li&gt;

&lt;li&gt;The Register: &lt;a href="https://www.theregister.com/2025/10/27/python_foundation_abandons_15m_nsf/?featured_on=pythonbytes"&gt;Python Foundation goes ride or DEI, rejects government grant with strings attached&lt;/a&gt;&lt;/li&gt;
&lt;li&gt;In Jan 2025, the PSF submitted a proposal for a US NSF grant under the Safety, Security, and Privacy of Open Source Ecosystems program. After months of work by the PSF, the proposal was recommended for funding.&lt;/li&gt;
&lt;li&gt;If the PSF accepted it, however, they would need to agree to the some terms and conditions, including, affirming that the PSF doesn't support diversity. The restriction wouldn't just be around the security work, but around all activity of the PSF as a whole. And further, that any deemed violation would give the NSF the right to ask for the money back.&lt;/li&gt;
&lt;li&gt;That just won't work, as the PSF would have already spent the money.&lt;/li&gt;
&lt;li&gt;The PSF mission statement includes "The mission of the Python Software Foundation is to promote, protect, and advance the Python programming language, and to support and facilitate the growth of a diverse and international community of Python programmers." The money would have obviously been very valuable, but the restrictions are just too unacceptable.&lt;/li&gt;
&lt;li&gt;The PSF withdrew the proposal. This couldn't have been an easy decision, that was a lot of money, but I think the PSF did the right thing.&lt;/li&gt;
&lt;/ul&gt;

&lt;ul&gt;
&lt;li&gt;&lt;strong&gt;7× Smaller Than JSON&lt;/strong&gt;&lt;/li&gt;
&lt;li&gt;A compact binary serializer for Pydantic models that dramatically reduces RAM usage compared to JSON.&lt;/li&gt;
&lt;li&gt;The library is designed for high-load systems (e.g., Redis caching), where millions of models are stored in memory and every byte matters.&lt;/li&gt;
&lt;li&gt;It serializes Pydantic models into a minimal binary format and deserializes them back with zero extra metadata overhead.&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;Target Audience:&lt;/strong&gt; This project is intended for developers working with:
&lt;ul&gt;
&lt;li&gt;high-load APIs&lt;/li&gt;
&lt;li&gt;in-memory caches (Redis, Memcached)&lt;/li&gt;
&lt;li&gt;message queues&lt;/li&gt;
&lt;li&gt;cost-sensitive environments where object size matters&lt;/li&gt;
&lt;/ul&gt;&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;&lt;strong&gt;Brian #3: &lt;a href="https://www.pythonmorsels.com/t-strings-in-python/?featured_on=pythonbytes"&gt;T-strings: Python's Fifth String Formatting Technique?&lt;/a&gt;&lt;/strong&gt;&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;Trey Hunner&lt;/li&gt;
&lt;li&gt;Python 3.14 has t-strings. How do they fit in with the rest of the string story?&lt;/li&gt;
&lt;li&gt;History
&lt;ul&gt;
&lt;li&gt;percent-style (%) strings - been around for a very long time&lt;/li&gt;
&lt;li&gt;&lt;code&gt;string.Template&lt;/code&gt; - and &lt;code&gt;t.substitute()&lt;/code&gt; - from Python 2.4, but I don’t think I’ve ever used them&lt;/li&gt;
&lt;li&gt;bracket variables and &lt;code&gt;.format()&lt;/code&gt; - Since Python 2.6&lt;/li&gt;
&lt;li&gt;f-strings - Python 3.6 - Now I feel old. These still seem new to me&lt;/li&gt;
&lt;li&gt;t-strings - Python 3.14, but a totally different beast. These don’t return strings.&lt;/li&gt;
&lt;/ul&gt;&lt;/li&gt;
&lt;li&gt;Trey then covers a problem with f-strings in that the substitution happens at definition time.&lt;/li&gt;
&lt;li&gt;t-strings have substitution happen later. this is essentially “lazy string interpolation”&lt;/li&gt;
&lt;li&gt;This still takes a bit to get your head around, but I appreciate Trey taking a whack at the explanation.&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;&lt;strong&gt;Michael #4: &lt;a href="https://github.com/antoniorodr/Cronboard?featured_on=pythonbytes"&gt;Cronboard&lt;/a&gt;&lt;/strong&gt;&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;Cronboard is a terminal application that allows you to manage and schedule cronjobs on local and remote servers.&lt;/li&gt;
&lt;li&gt;With Cronboard, you can easily add, edit, and delete cronjobs, as well as view their status.&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;✨ Features&lt;/strong&gt;
&lt;ul&gt;
&lt;li&gt;✔️ Check cron jobs&lt;/li&gt;
&lt;li&gt;✔️ Create cron jobs with validation and human-readable feedback&lt;/li&gt;
&lt;li&gt;✔️ Pause and resume cron jobs&lt;/li&gt;
&lt;li&gt;✔️ Edit existing cron jobs&lt;/li&gt;
&lt;li&gt;✔️ Delete cron jobs&lt;/li&gt;
&lt;li&gt;✔️ View formatted last and next run times&lt;/li&gt;
&lt;li&gt;✔️ Accepts &lt;code&gt;special expressions&lt;/code&gt; like &lt;code&gt;@daily&lt;/code&gt;, &lt;code&gt;@yearly&lt;/code&gt;, &lt;code&gt;@monthly&lt;/code&gt;, etc.&lt;/li&gt;
&lt;li&gt;✔️ Connect to servers using SSH, using password or SSH keys&lt;/li&gt;
&lt;li&gt;✔️ Choose another user to manage cron jobs if you have the permissions to do so (&lt;code&gt;sudo&lt;/code&gt;)&lt;/li&gt;
&lt;/ul&gt;&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;&lt;strong&gt;Extras&lt;/strong&gt;&lt;/p&gt;

&lt;li&gt;&lt;a href="https://courses.pythontest.com/lean-tdd?featured_on=pythonbytes"&gt;Lean TDD&lt;/a&gt; book will be written in the open. TOC, some details, and a 10 page introduction are now available. Hoping for the first pass to be complete by the end of the year.
&lt;ul&gt;
&lt;li&gt;I’d love feedback to help make it a great book, and keep it small-ish, on a very limited budget.&lt;/li&gt;
&lt;/ul&gt;&lt;/li&gt;
&lt;/ul&gt;
