Krisman: Using the Linux kernel’s Case-insensitive feature in Ext4.We care about the content and the semantics of the words IMPORTANT and REPORT. When people write titles, ‘important report.ods’ and ‘IMPORTANT REPORT.ods’ usually mean the same piece of data, and you don’t care how it was written when creating it. Traditionally, Linux (and Unix) filesystems have always considered file names as an opaque byte sequence without any special meaning, requiring users to submit the exact match of the file to find it in the filesystem. In other words, a meaningful file name is what people rely upon to find their valuable documents, pictures and spreadsheets. While, from the operating system point of view, it doesn’t matter what the file name is, as long as it is unique, meaningful file names are essential for the end user, since it is the main key to locate and retrieve data. Most, if not all, of the information described here also applies to f2fs, with small changes on the commands used to configure the superblock.Ī file name is a text string used to uniquely identify a file (in this context, ‘directory’ is the same as a file) at a specific level of the directory hierarchy. More recently, f2fs has started to support this feature as well, following the Ext4 implementation and framework, thanks to an effort led by Google. Therefore, this seems like a good time as any to take a look on why this was merged, and how to put it to work. Now, one year after this quite controversial feature was made available, Collabora and others keep building on top of it to make it more and more useful for system developers and end users. Linux 5.2 was released over one year ago and with it, a new feature was added to support optimized case-insensitive file name lookups in the Ext4 filesystem – the first of native Linux filesystems to do it. Using the Linux kernel’s Case-insensitive feature in Ext4.That topic is now being further explored at this week’s virtual Linux Plumbers Conference and it’s still looking like it will happen, it’s just a matter of when the initial infrastructure will be in place and how slowly the rollout will be.īack in July, Linus Torvalds shared his thoughts on Rust within the Linux kernel tree and didn’t shoot down the idea just his preference on how it be handled, basically having it be enabled if Rust is present on the system. Linux Developers Continue Evaluating The Path To Adding Rust Code To The KernelĪs mentioned back in July, upstream Linux developers have been working to figure out a path for adding Rust code to the Linux kernel.Are My Linux Videos Too Long? They Might BeĪ lot of the videos I make are Linux software showcases but I’ve had a few people mention that some of my videos might be a bit too long so I thought I’d explain why my videos end up being as long as they are and how I’m slowly stripping down the videos as I improve upon my style.Python Bytes: #196 Version your SQL schemas with git + automatically migrate them.We discuss his article “Options for Packaging Your Python Code: Wheels, Conda, Docker, and More,” covering the how of sharing your code. This week on the show we have Itamar Turner-Trauring, creator of the website. It depends on what the code is, the libraries it depends on, and with whom do you want to share it. Have you wondered, how should I package my Python code? You’ve written the application, but now you need to distribute it to the machines it’s intended to run on. The Real Python Podcast – Episode #24: Options for Packaging Your Python Application: Wheels, Docker, and More.Thanks for listening and, if you happen to get a chance, feel free to call us or e-mail and send us some feedback. This is our bi-weekly departure into the world of amateur radio contests, open source conventions, special events, listener challenges, hedonism and just plain fun. Topics include writing, the industry’s move to ARM, the Linux community in general, and more. We spoke about some of my current projects, and our views on some of the recent happenings in the industry lately. I had a chance to sit down and chat with Mike Dominick recently, on August 25th 2020. Interview from Episode #34 of The Mike Dominick Show (Audio Only).
