0:00 How Ben got started with Emacs
Sacha: I forgot to ask you how your last name is pronounced. Ben: Oh, Zanin. Sacha: This is Emacs chat number 25 and here I am with Ben Zanin. You have a math background and now you're in IT. Where did you encounter Emacs in the journey? Ben: So the reason I have a math background is that I wanted to get into programming language design and at the time so that led me over to lambda calculus and that kind of thing and at the time it was at the time I was getting into university in like 2005-2006 It was impossible to get into the computer programs, but I could get into math. I figured that would move me in the direction that I wanted to go in, so I did. Got to third year, and then every professor who taught any of the courses I cared about all left the faculty at the same time. Sacha: Oh no! Ben: Yeah. Anyhow, that's a different story. But yeah, I got into Emacs because in the process of learning about Lambda Calculus, the Lisp weenies found me. And yeah, I spent a bunch of time learning about that. And it wasn't until like 10 years after I got into Common Lisp and Scheme that I actually got into Emacs at all. Sacha: That's interesting. Usually people, like, if they're doing Lispy things, they get into Emacs right away because Lisp. But okay, so 10 years after. You're already well-used to parentheses at that point. Ben: Yes. But I guess it wasn't until about ten years ago, like around 2015 or so, that I started really getting into Emacs. I would still consider myself to be a beginner on that front. Sacha: Oh yeah? So what got you to get into it more? Ben: I found that I was looking for more structured data management processes. Basically, I was looking for personal information management. And I kept bouncing off Emacs because I wanted to get into those tasks, but Emacs was such a rich learning process that I kept getting sidetracked, so I kept bouncing off of it. 2:19 Ben got into Emacs because of twittering-mode
Ben: But I have to admit that one of the things that originally actually got me into Emacs was twittering mode. Oh yeah? Because I was looking for a tool that would let me, we'll probably get into this later in the chat, but I was looking for a tool that would let me keep a larger window of context about the conversations that I've been in. The Twitter apps and the Twitter website implemented a really narrow window. I wanted to be able to search back a couple of weeks for stuff that I had seen or talked about previously. Twittering-mode gave me the ability to keep days or weeks of context in a single buffer that I could then immediately search. So I didn't actually get into Emacs as a text editor, I got into it as an application platform, and then gradually learned the rest of it. This is actually fantastic. So I kind of stuck around after that. Sacha: That is the first time I've heard of someone coming to Emacs because of Twitter. Ben: No, it's deeply embarrassing. Sacha: No, it's wonderful. I love that there's just so many reasons why people come and the fact that you could find something that would let you take those notes and see that context and reply to it, and even, as I see in your config, work around slow keyboard response issues. Ben: And also the fact that that's still in the config despite Twitter itself... I think I abandoned it in 2017, but it takes me a little while to rip things out of my config. Sacha: Yeah, I see you're a lot more active in Mastodon these days. I see your Monsterdon posts scrolled by my feed every so often. Yeah, so we dove right into that because a lot of the stuff in your config is interesting and your workflows too. My idea for these Emacs chats is to show people the kind of stuff that isn't immediately obvious to newbies when they're looking at someone's config. Because a lot of the stuff is new workflows and how the keyboard shortcuts work together and how this stuff fits into your life. That's not immediately obvious from the code. I've taken a look at your config, but before we jump into the gazillion things I wanted to ask you about, are there things that you particularly love about your Emacs workflow? 4:30 Emacs as a media playback platform with Versuri and Mpdel
Ben: I'm probably going to get a little bit of deserved flak for this, but I use Emacs a lot as a media playback platform. I spend a lot of time using Emacs to listen to music through MPV. And I've got some integration with Versuri, which lets me... I think you've seen those customizations where what I've done is I've kind of duct-taped the two together. Versuri is an Emacs package for being able to quickly search through lyrics for songs. What I've done is I've bound Versuri to the point where I've pulled up a page of lyrics, I now have a hotkey that bounces me over to a search of my MPD library for where that song is, and vice versa. I've got MPD rigged up so that when I've got a song currently playing, I can bounce into Verisuri to display the lyrics for that particular song. Something you probably have not seen in my config yet because I haven't finished it yet... What I'm working on is actually integrating Org Mode with MPD, because I'd really like to be able to streamline my process where occasionally when I'm listening to something, I'll take notes either about the lyrics or about the song. I'd like to be able to link from Org Mode directly to either that song, that album, or that particular timecode. I don't have that yet, but I'm working on it. I think I'll probably lean on it quite a bit once I have it. Sacha: Yeah, yeah. I saw your tweet from May, I think, where you're talking about coming up with this way of taking notes. think if you come up with maybe a custom Org Mode link type that can store the annotation and then let you go to it, I think that would be really interesting. Especially if you figure out, okay, like, are you taking notes in the album? Are you taking notes on the song? Are you taking notes on this moment in the song? That could all be very cool. Ben: Actually, do you mind if I share my screen? Sacha: Please. Ben: So one of the things I wanted to kind of note was... Let me... Oh yeah, this is actually going to be further embarrassing. I'm a terminal Emacs user. Sacha: I saw. Can you increase the font size, though? Ben: Absolutely, yeah. Sacha: Resizing your terminal so it's smaller makes everything look bigger... Ben: Is that better? Sacha: More. Some of us are older. Thank you. Ben: One of the things that's kind of unusual about my MPD configuration is I've got a satellite config. Sorry, the line wrap is a little bit off here. What this means is that I have... the household file server maintains the MPD library, but I've got multiple playback nodes around the house. What that lets me do is... Sacha: You can play stuff on this... Ben: So what this means is that I'm controlling the... well, in this case, that's a little MeLE Quieter3C that I've got in the living room that's kind of like the the home media server, the home playback machine. Fundamentally, I'm an ops guy, I'm a sys admin, and I've got, unfortunately, a fleet of machines around the house. What this lets me do is easily control each one of them. Instead of each one maintaining its own library of music files, the file server itself indexes them, which means that library updates are almost instantaneous, instead of having to read over the network to pull metadata out of each individual file. So having a satellite setup lets me... The real benefit is that MPD tracks albums, directories, and files as URLs. That means that I have a single global namespace of URLs for all of the media that's currently in the library, which means that I can annotate from any machine, but have it mean one thing. It makes it convenient for navigation, but it also makes it convenient for keeping notes, which I'm currently doing manually and working on those Org link types to be able to make it a little bit more smooth than it currently is. Sacha: So you've got your central store of music files. You've got URLs for them so you can talk about them. That's just one identifier per song. You've got multiple speakers that you can use your completing interface to say, okay, I want to play this over there. You have Emacs controlling all of that. 9:13 Emacs on Android with Termux
Sacha: Now, is that Emacs on your laptop and you just take it around and you say, okay, I'm going to sit in the living room for a little bit or whatever and play there. Or do you... Ah, there you go. That's what I was going to ask. All right. So Emacs on your phone. The Android port or Termux? Ben: I have both installed. I think you actually saw this a few months ago when I was running performance comparisons between the Termux version of Emacs and the native port, and found that the native port generally ran anything CPU-intensive roughly twice as fast. But I still use the Termux version because it's... I'm not sure if you played around with the Android terminal virtualization layer at all, but it's not great. I really appreciate the integration that Termux gives me with Android features. For example, being able to query the sensors, such as GPS or temperature sensors, and I can actually pull those in from the Emacs side. And that's something I kind of want to get into. Sacha: What do you think of using the temperature sensors for? What can Emacs do with that? Ben: It's not so much the fact that I use the temperature sensors as that when I pull the sensors, that's the most remarkable value that I get out of it. But so like one of the interesting things is the barometric pressure sensor, which gives me Height, which matters because when I'm out and about and if I stop to record an entry in my journal, for example, I'll just pull the sensors and dump them into the header in the entry that I'm writing. The barometric sensor, I'll get the GPS, so that'll tell me what the actual height is at that location on the earth, but the barometric sensor also gives me a little bit of insight into the weather. So like it's not so much the temperature sensor is like what my temperature is, but just like if it's a hot day or not. Sacha: I am very curious about that setup. So if you happen to share your, I don't know, Org capture for Termux that includes all these things. You don't have to show me the actual stuff, but you know, at some point I think other people will be curious about what kind of benefits they can get from running Emacs on their phones. Ben: So, I mean, I guess I'll... One of the benefits that I get is the ability to Keep shopping. So I'm a little bit of a militant cyclist. And one of the things that I often do is leave notes about things that I need to take care of in particular areas of the city. And the nice thing is that I can just drop them directly in commits right as I'm going. So I often have a long list of updates that are from Emacs on my phone just because it's convenient. All right. There we go for Monsterdon, in fact. Sacha: Nice, nice. And then that's, you know, I don't know, sync thing or whatever else to just get it copied back to your laptop. Just on your phone. Oh, yeah. Ben: And that's one of the things that I found was a little bit clunkier when I was running virtualized Emacs under the Android emulator and also the native Android port of Emacs. They are a little bit more troublesome to get Magit to work. And because I rely on that for syncing back and forth from my phone. That's one of the reasons why I stuck with Termux. Sacha: Very cool, very cool. I like Termux's, that little bar of extra keyboard keys that you can have, so you can have a regular keyboard and then you can just have your controls and your outs and whatever on that little extra bar. So Termux is quite interesting. Ben: I think I'm probably pushing it harder than it is meant to be pushed. Sacha: That's the fun of it. I don't exactly know how everything will shake out, but probably with Google trying to lock down the developer ecosystem in a few months, right? They're saying, oh, you know, it's got to be ADB in order to get these unsigned apps on. We'll have to see how it all shakes out. But I'm hoping Termux can survive because I like that one too. Ben: Yeah, me too. Sacha: Okay, so you've got interesting music, an interesting music setup with lyrics and playback and all that stuff. You've got your phone, which also runs Emacs and from which you can, you've also set it up so you can control your music from your phone? Ben: Yes. Sacha: Okay. 13:44 Keyboards
Sacha: When I was reading through your toots, I noticed you like to play around with other keyboards and other devices like the 8BitDo. Do you have any of that talking to Emacs too? Ben: [Keychron B11 Pro is] the keyboard I'm currently using. I got this so I could keep it in my purse and just like walk around with it, but it turns out it's super comfortable and I'm accidentally using it as a daily driver. Sacha: All right. Named out the keyboard for all the people who like the device recommendations. Ben: It's a Keychron B11 Pro. It runs ZMK. ZMK, I suppose. And if you've seen me interacting with Pete Johansen, El Mastodon, he's the lead developer of that firmware package. It's a little bit like QMK, except that it's fundamentally QMK is a polling architecture, and it works really well for very restricted microcontrollers. ZMK is... It's interrupt-based, which means it is tremendously more efficient in terms of power draw. So if you want a Bluetooth keyboard, you should probably run ZMK on it. Anyhow, yeah, it's fantastic. And I do have a bit of a keyboard problem where I tend to... Many Emacs people have keyboard problems. Right? I feel like I'm in good company right now. Sacha: Yeah, yeah, yeah. So that, devices, yep, gotcha. And this has become your main keyboard even for regular computing? Ben: In the last couple of weeks, yeah. It's super comfortable. And because it's so flat, I can get away without having to use palm rests to actually keep in a decent posture. And because of the curvature of it, Like it's an Alice layout. And the key travel isn't too bad. It's actually quite comfortable. I found that I needed a little bit of acclimatization to get used to split keywords. But this one has this, like roughly the spread of a split. But it seems to be easier for my muscle memory. So yeah, I didn't intend to leave it on my desk, but it just, it stuck and has kind of stayed there for now. Sacha: Does it have any special ergonomics for all the modifiers that we like to do? Or do you just use Caps as Control or whatever else? Ben: Actually, I don't use Caps as Control and I actually really need to get into remapping that. ZMK has a very rich remapping story, as I expect you to imagine, from a custom firmware. And the macros are intense, and you can get really deep in customization. And I have done none of that on this keyboard yet, because it's only, I think, a couple of months old at this point. Sacha: You've been settling in. As you said, this has been your main computer, main keyboard for a little while. Charlie Baker says, yeah, I love the split keyboard. Recently bought one myself. I was getting so much neck pain, you know, shoulder and neck pain from so many hours keeping hands close together. But the split lets his shoulders relax. So probably you're getting the same, like, ah, my arms. Ben: Yeah, like the two things that I, oh, sorry. Sacha: Go ahead. No, no, no, go ahead. 16:44 Benefits of a split keyboard
Ben: The two things that I first noticed when I moved to a split keyboard was one, my wrists started feeling a lot nicer and two, I was immediately able to bench press like 20 pounds more the next week. It was amazing how much of a difference it made and it showed up in the data. Sacha: Wow. There was a weightlifting talk at EmacsConf last year, I think. So there's a surprising overlap between the people who are checking their weightlifting stats and the people who are into Emacs. Naturally with Org Mode. There you go. Ben: Let's not look at those numbers too closely. I'm not too proud of a bunch of them. But yes, I find that Org capture templates let me keep on top of that and not really think about it, which is great because you don't want to think about it. You want to gather the data and think about it separately so that you can stay emotionally divested from what the numbers mean. Sacha: I know. I'm totally happy to dig into the Org capture, especially if you do any graphing. People always love graphing their progress, right? But if you're like, I don't really want to show my numbers at the moment, that is also understandable and okay. Ben: I don't, I'm afraid. Sorry. Sacha: That's okay. Ben: It took me a couple years to get used to being on camera at all. I don't really like my appearance very much. I'm working on that, as you can see. I've had to work on that to be able to work remotely. It's a work in progress. I'm getting through it. Sacha: You know us. We're very much focused on text. In fact, you even use Emacs in the terminal. That's very text-y. 18:22 Meeting workflow
Sacha: One of the interesting things actually that I wanted to ask you about since you mentioned meetings is you probably also have the role of designated note-taker. You mentioned in one of your toots that you take notes and people are like, what are you doing that in? How are you taking your notes? And it's Emacs. Ben: Yes, so actually that's one of the things I should lead off with as an apology. I probably won't be able to share many of my capture templates because I don't use them in my personal life very much. They're mostly on my work machine and like I've got capture templates for impromptu meetings where it's just like an exploratory, we have a problem we need to solve, we're kind of talking through a discussion. A separate capture template for meetings with agendas to make sure that we stay on them and that we log decisions. and a separate set of templates for... So I have a team of direct reports and they each have different cares and different topics that we're working to develop in their professional careers. And I find that it's really useful to be able to keep some continuity between our conversations. And it also makes it very easy to export that entire dataset, share it with them to make sure that they can consult it at the same time. And if I got anything wrong, I can fold their corrections in. But all of those templates, unfortunately, are on my work machine. Sacha: We'll just sketch out the general idea in abstract details and then people who want to implement it for themselves can fill in the blanks. For example, when you're having a meeting with your direct reports, are the tasks related to them in an Org agenda? Are you using dynamic blocks? Is it tracked somewhere else or is it in Org? Ben: It's straight in Org mode. So most of the touch points that we have are more about professional development and their cares and concerns rather than specific deliverables. Usually deliverables we manage at a team level. But if there are specific things that individuals are working on, they will be in to-dos under their subheadings in a way that show up on the agenda if we have assigned deadlines for them. But generally, if there's a deadline on a task, it's because I'm doing something and they need to track it, or they're doing something and I need to track it. And if I'm the only guy using Emacs, then Org Mode won't work for that. So there aren't a lot of those. But if it's just something that I need to check up on to make sure that something that like they've got planned leave for example or like they have a cousin's wedding that they need to go off to or something that I just need to keep in my brain that's not necessarily deliverable then that would it would be appropriate to keep that in a place where it'll only show up on my agenda. So that's the kind of decision making that I apply there. 21:11 Narrowing
Sacha: And you mentioned you have like a subheading I guess as a subheading per person or sort of or do you use tags to kind of keep track of something that might touch several people? Ben: Usually a section per person and that's more of a convenience than anything else. That lets me narrow to just that subheading and share my screen during the meetings. And then I don't have to worry about accidentally leaking anybody else's information into the screen share or anything like that. And obviously we let off with conversations about them being all right with that. But the ability to very clearly and simply delineate This domain of my notes pertains to this person. And being able to be confident and share that confidence that there will be no leakage means that we can explore topics and talk about them in a way that might otherwise be a little bit more restrictive. So being able to do that simply and being able to establish a very clear delineation around whose information belongs where and where it should be shared turns out to be pretty valuable. Sacha: Yeah, and that's a technique I think that especially people who are new to Emacs and who aren't used to narrowing and widening might not know how to use effectively. I think narrow is even one of the commands that's disabled by default. You've got to say, yeah, you know, I'm not scared. I know what to do. Ben: Yeah, it's kind of bizarre to me that it is, but yeah. Sacha: I can imagine people accidentally triggering it and they're like, oh no, the rest of my file is missing. But if you know how to narrow to a region, and Org even has those commands to easily narrow to a subtree. I think it's even part of the default speed command so you can trigger it right from a heading. But it's great for that kind of restriction. 22:58 There's even an internal Slack channel about Emacs at Ben's company
Sacha: Okay, so the reason why I was asking about that is because some people are working with people who are not using Emacs, so it's very interesting to see what the kinds of... It's very rare for people to work with other people who actually use... Are there any other Emacs people in your company, for example? Ben: There's an entire Emacs Slack topic about that, yeah. It's kind of great. Sacha: What is that like to have co-workers who do Emacs? Because this is a rare experience. Ben: It's super cool. It's also neat to see the very, very different ways that people use it. But yeah, oftentimes people will talk about problems that they have with particular internal tools, and somebody's like, oh yeah, go check out this repo on GitLab that I published last week where I got sick of it and decided to solve that problem categorically. It's actually super cool. And some of the folks at... Generally, I tried not to mention my current employer at any point. Obviously, it's not secret. It's in the init file. But yeah, I don't tend to get into that deeply. But some of the other people who work at my company, they maintain venerable Emacs packages. So it's awesome to be able to go and talk with some of the folks who I've been working on the code that I've been using for a decade and we are now coworkers. It's lovely. Sacha: Oh, that's so nice. I'm glad you have that kind of little community in there. Yeah. Bunch of nerds. So I suspect some people will be looking up your company after this. I think it's also mentioned in LinkedIn and sort of like, okay, let's see if there's any job openings. Ben: If it's mentioned on LinkedIn, that is somebody else. I haven't logged into LinkedIn in 15 years and I never will. 24:47 Ben keeps Org capture templates as individual files and adapts them to different meeting flows
Sacha: We do have a question from Shae. Shae is asking, how do you make a capture template to stay on agenda and record decisions? You got any tips for that? I'm guessing this is more of a human thing rather than an Org thing, but maybe you have some ideas on how you keep something on track. Ben: So I'll actually push back on the it's a human thing rather than an Org thing. So I strongly believe that one of the real values of Org Mode is that it's a very plastic system. Fundamentally, I think that it is a human system because it allows you to express exactly those kinds of trade-offs in a really, really fluid way. I love the personal information management that Palm Pilots provided, for example. But it was pretty restrictive. And one of the things that I love about Org Mode is that if you find that a particular person has a particular conversation style, it's really easy to modify your Org Mode capture templates to be able to capture that particular flow that you have with that person. Or with a particular group of a recurring meeting, for example, that tends to flow in a particular way. Super easy to update the templates that I use to capture those particular meetings to make it easier to match the general conversation flow with the notes that I will be taking about it. Sacha: Wow, that sounds pretty sophisticated. Ben: Well, I mean, that's the thing. It's not sophisticated. It tracks the human process very easily. So it's really lightweight. So you don't have to have a lot of sophistication to make it very, very useful. You just have to have a feedback loop that you can tune every time with one or two minutes of effort. And that's one of the reasons why I depend on Magit mode so much is that it lets me track those things. But yeah, to answer Shae's question about how do I track those particular things. So if it's a meeting where one of my direct reports has a particular set of topics that we tend to investigate, like somebody who's concentrated on career growth. So we're talking about the areas in which we want to see development. I'll absolutely update the capture templates for that particular person to say, all right, here's what we talked about last time. Here are the things that were done between our last two conversations about how we move in that direction. Were they successful or not? Did it require a lot of effort? So was it something that more effort should be put into to be able to drive down the work over time, to be able to produce those results? But yeah, that goes into the templates and that goes into the cadence of conversations that we talked about in Capture. Sacha: So that's really interesting. You modify the Capture templates with kind of the notes that you want to have easily available the next time you chat with them. Exactly, yeah. Like the capture templates are still defined as a setq somewhere in your thing, or are you going into the customized interface? Ben: So I actually keep the capture mode templates as raw files that are referred to, and that makes it easier to version them in a way that like, I mean, sure, like my Emacs init file, if you look at the Git history of it, it has a whole bunch of different, well, it has a, actually, where would I, yeah, okay. Sacha: I had not considered having capture templates as file spells. It worked out really well. Ben: So you can see that it's a little bit hard to see with the font this small, but you can see that I've got a lot of changes to, for example, my init file, but keeping them in individual capture mode template files makes it a little bit easier to just look at the history of that particular file and see why particular changes were made. Sacha: I'm going to try that. I think that's a great idea because it allows you to be a lot more granular about the notes. 28:45 Personal-scale software and the journey
Sacha: I saw in that very brief flash of your change log message that you like to write Fairly detailed commit messages that talk about why a change was made instead of just a new function, new command. Very terse updates that I sometimes just try to get away with. Tell us more about that because I think you've had a couple of toots about reading source code and reading commits. Ben: Yeah. So I guess One of the things that I most appreciate about software in general, and specifically personal software, like personal scale software that's been written by an amount of people that you could fit into a room to have a conversation about it. One of the things that I most appreciate about that is that almost all software written that way is fundamentally a diary about the way that a person learned how to solve a set of problems that they might not have known about when they decided to at the beginning. It's this fascinating process of Tracking somebody's voyage through the problem landscape as they discover other people who have touched on topics that are tangential to the problem being solved by that software package. It's such a personal and fascinating experience to see somebody go from, I know just enough about a problem to be able to decide that I want to build the machine that works on it, to I have this deeper understanding of how the problem actually exists in the broader set of things that people care about. ...oriented along the axis of what machinery can do to help solve parts of that problem. And like the commit logs for a program are like just this, it's like a map through that territory. It's wonderful to read, but it's also like... It gives you a lot of insight into the person doing the navigation. When you see 16 commits on December 24th of 2023, like, oh, okay, that person probably had a little bit of time to work on it. And then when you see a bunch of commits that are like 5 p.m. Monday to Friday, like, oh, okay, this is probably done in a particular way. But yeah, it's this deeply personal process of seeing how problems are learned about. And I just really appreciate that. Sacha: I think what you're saying about personal scale software and kind of getting a sense of people's journey as they learn to understand a problem and as they start to prototype a solution because you never quite come across the right solution the first time around. You're figuring things out. You're borrowing things from other people. I think that will resonate a lot with lots of people in the Emacs community because Emacs use is so personal as you mentioned when you were looking at the Slack channel. I was wondering, in your personal practice, as you figure things out, what kinds of things help you? Is it mostly a matter of actually sitting down and taking the time to write the literate programming stuff around the code blocks or the commit messages? Or are there other tools or techniques that help you do that? Are there tools or techniques that help me write down your journey along the way as you think about the code? What's your practice? For example, when you come across something that you want to figure out, how do you go about doing it? Ben: So it depends on how I'm approaching the project. So one of the neat things about software is that it's a document and a device at the same time. So you can care about it because of the thing that it does, or you can care about it because of the information that it captures. And if I'm digging into a program because it does a thing that I want to learn, then I'll pay attention to the device aspect of it. And that usually means that I'll start with its own documentation. So if it has a man page, I'll read that. If it has user docs, I'll read those. And usually I'll start keeping notes in an Org Mode file because it's easy to hyperlink back to it and add my own annotations in parallel to the actual authoritative source. If I'm reading software primarily as a document, then I'll start by reading the source code and the commit logs, usually the most recent ones, and then I'll jump back to the beginning of the project and read upwards at the beginning, and then fill in the blanks iteratively if it's a project that's small enough or has little enough history that I can do that. And again, I'll usually start an Org Mode file specific to that particular exploration that will let me organize my notes as I go. I really do rely on the external brain that I can keep in an Org Mode file. I tend to have a pretty decent long-term memory, but being able to bridge the gap between short-term memory and long-term memory is super, super useful. So leaving myself hints that let me dredge things back out of long-term. Reloaded into the hot cache of short term really, really helps out because that lets me maintain that flow state or get back into that flow state when you've got like the whole program, all the context that you've absorbed up until now and the ideas of like the areas that you want to investigate. Being able to hot reload all of that and then pick up where I left off is super useful. But the meat brain can't do it. I need the machine brain too. 34:07 vc-git-grep for finding notes again
Sacha: Tell me about this dredging up process. Are you a lots of little files person? Are you a couple of large files? Are you a project file? There's an Org file in each project that you look up. How do you find things, especially if you don't remember the exact words? Ben: So it's usually like an Org Mode per category and they get consolidated. Let me shrink this down a little bit. So usually it's an Org Mode category per file. If there's something super specific, then usually it'll kind of live out in its own place until I get around to... I love that you have an Org File specifically for Mud Cake. But that's the thing. It'll live off in its own thing until it gets integrated into the list where the long-term stuff lives. So, for example, I promise this is pertinent to your actual question. Sacha: No, no, this is very pertinent. Ben: But so like usually lots of little files while I'm still working on something and then as that something becomes part of my larger life and has links to other things then it'll kind of get centralized into one of the Org Mode files that has a broader topic purpose basically. Sacha: Okay and then if you if it's like very long term and you can't remember the exact rates to find something how do you generally find find your notes? Ben: That way. Sacha: All right. You start graphing various keywords and try to find it. Ben: Yeah. So one of the things that I don't yet have turned on, and actually you inspired me to look into this, was so... Actually, do we have enough time? Yeah, okay. So I'm just looking at the clock. One of the things that I wanted to get into was long-term searching and searchability. Yeah. So I use SQLite's indexing for a lot of things, and I really appreciate its Porter stemming because it lets you search for stemmed words, which are kind of approximate matches, which is useful, but less useful than vector databases. And you actually put a little bit of work into indexing topics based on vector similarity. Sacha: Which I haven't gotten back to, so I'm glad to see, you know, you managed to experiment with it. See what you come up with. Ben: So I don't have anything to show yet, except that it's an interesting topic because... Because I'm word-oriented, I will often remember individual keywords or I'll have enough patience that I can sift through a list of potential keywords as I'm grepping for stuff. And if I find that my first three or four attempts at searching for a keyword don't find the topic that I'm looking for, once I do eventually dig up the topic, I will add those keywords that I was searching for just so I can find it next time, expecting that future me will probably behave more or less like current me. But yeah, like being able to use a vector database to search for headings that include related topics instead of related words. I'd really like to get there. I'm not there yet. And I think that's going to be interesting and useful. I also think it's going to be challenging to kind of represent Org modes. hierarchical structure to restrict the training of particular vector sets to be able to find like an increasingly or cast an increasingly wide net for where I want the searches to run. So I don't know how that's going to be solved yet, but I'm going to be looking into it. 37:47 Keybindings and terminals; wezterm
Sacha: Percopop has a question regarding terminal Emacs. Do you need to change any of the keybindings to avoid clashes with the terminal? You know, some keybindings don't work on terminals, or some terminals already have these keybindings set. Ben: Yeah, so I have good news and bad news there. The good news is that, so one of the terminals that I'm using right now on most of my systems is Westerm. It's really good. I started off with Alacrity and I kind of bounced off that project because of some of the behavior of the lead developers. I won't get too deep into it, but what I found is that Westerm It gives me very little friction that way. It doesn't have a lot of its own key bindings on its own, and that's a relief. It means that I really don't have to... I don't think I've had to put any time into customizing Western to get out of the way of Emacs or Screen. And I should mention, I am running Emacs within Screen. So that introduces another layer. Control-A-A, for example, is beginning of line for me, even though Control-A itself is the default Emacs keybinding. But yeah, I think that I ended up choosing terminal software specifically on that merit, so that it doesn't get in the way. That's actually one of the things that Termux is... The default Google keyboard keeps stealing key bindings. It'll update and all of a sudden I can't use a particular alt key combination anymore because now it invokes a Google keyboard shortcut for pulling things out of the Android clipboard, for example, which is really kind of annoying. But yeah, in terms of terminals on full-fledged machines, I generally don't have that particular problem. Except for... What was the name of it? It was... It was a zap-to on-the-screen package that alphapapa wrote, I believe, that I... Actually, let me just look it up. Yeah, Avy. Sacha: Oh yeah? Ben: So I wanted to start picking this up in 2021, and yeah, control colon doesn't work in terminals. So the mode itself is fantastic, and when I'm using it in a GUI Emacs, it's very useful, and I rarely use it now specifically because of that particular terminal problem. That is self-inflicted. That is not a problem with the package. That is a me problem. But yeah, I think this is the notable one that I bounced off of. Sacha: Yeah, just trying to find the right, you know, a key binding that will pass. Because you can't get used to key binding in one system and then not have it available in other systems. It's just going to mess with your brain. So yeah, Ray points out, yeah, Google steals Control Shift K, which he uses to kill tabs to the right. So it's like, oh. Ben: Infuriating. Sacha: Yeah, yeah. And of course, none of the standard keyboards have a super key on the thing, so you can't just tack on another modifier that'll get through. Ben: That's actually one of the reasons that I picked up this particular keyboard is Brian Carlson. Another Torontonian. He works on Git LFS and some other stuff. He was specifically looking for a keyboard that had a super key that he could remap. So four keys to the right of space, which this one has. And because it's ZMK, it's remappable. I think this might be suitable for his purpose, except that he wants a QMK keyboard, specifically because the development tools for QMK are packaged in W, and that's a plus for him. Anyhow, yes, I agree. Like, not having a super and a hyper key on a keyboard Sacha: feels like like one of your fingers that are cramped up we need more modifiers well I mean you know pipe organ Tell us about that. Ben: What is this? Oh yeah, foot pedals. Yeah, and I actually do have these wired into a little Atmel microcontroller running QMK. I honestly tried the foot pedal thing for a little while. It was hilarious. I did not find it useful. Sacha: I don't have the hand-eye-foot coordination to do that thing at the same time. Ben: Maybe if I had learned piano as a kid, it would have been good. But yeah, I don't seem to be able to do it. But I gave it the old college try and it was fun. 42:38 Timers: tea-timer, tmr
Sacha: Okay, I had a couple of things I wanted to ask about in your config. You have two types of timers. You have tea-timer and you have Prot's TMR. Do you use them for different purposes? What's going on here? Ben: So I'm trying them out. I tried TTimer first because it was the first one that I found, and it was useful. I was actually using it in meetings because I would, when I was trying to keep us on topic, I would use that to remind us that, oh, we've got four other topics we need to get through. We're trying to give this one five minutes. We're running up on four. And it was just because it was super low overhead. It was easy to pick up. It was easy to have it displayed on my screen. And it didn't feel like I was... Running a chess timer on everyone. It's very subtle in the mode line. It was useful. But what I found was that when I was... Running multiple timers simultaneously. TMR, just the fact that you can list all the timers and manage them in a separate buffer. It's richer and I appreciated some of its documentation more. I haven't fully switched over to it yet. I'm still in exploratory mode. In fact, this is probably like... So I actually have a bunch more packages installed than I'm currently using. So I'm going to shrink this down a little bit just so that it doesn't line wrap. 43:57 Different stages of package use
Ben: But yeah, so I've got, I think about 140 packages locally cloned. I've got, as you can see in my init, about half of that actually installed. There are various phases. I've got a clone, but I don't have it in my init. Or I have it in my init, but there's another package that offers similar functionality. Or I'm all-in on this particular choice and I'm removing the other ones. It's a gradual kind of progression. Sacha: Yeah, we're all auditioning packages to see if they fit in our workflow and all that stuff. I was curious also about your elfeed things. You have a few things related to elfeed. Actually, do you want to talk about the thing you just highlighted first? Ben: No, we'll get back to it in a sec. I'm keeping an eye on the clock. Sacha: But yeah, elfeed. 44:47 Elfeed
Sacha: Yeah, you've got a couple of interesting things in your elfeed setup, including picking a search from a bookmark or other shortcuts like that. Ben: So I have discovered in my conversations with the new maintainers for elfeed that my elfeed habits are very deviant. So let me actually start off by going through... You can see that like the top of my elfeed list is kind of in one format and down at the bottom, the ones that are closer to present day are organized in a different way. Sacha: You've got tags now. Ben: So my feed list is, I mean, it started in Google Reader. It's kind of been forward ported since then. It's long. Sacha: I love the comments. Ben: But one of the consequences of having a long feed list is that I have an enormous elfeed database. And I use it for completely different purposes. So for example, I'm going to show off that little default search. I keep an eye on projects that have releases that aren't packaged by Debian, for example. So I've got this little ATS Mini. basically a small AM FM radio that happens to run on ESP32 and the firmware for this community developed and it's kind of interesting but like that's not packaged by Debian so I pay attention to or I subscribe to the release feed for that particular project. I do keep in keep an eye on the Linux kernel especially these days because The gallop of security vulnerabilities coming out of mythos analyses right now means that I have to pay more attention than usual to fresh updates. So generally I run Debian stable, but I do run kernels from backports and I want to know when those are available. MeshTastic. I was paying more attention to this a couple of weeks ago. I'm not going to reach that right now. But yeah, the local MeshTastic community in Toronto is plagued by a couple of griefers that make it a lot less fun. So I'm paying a bit less attention to that right now. But yeah, so like one of the bookmarks that I have is software currency. Another one is, for example, the YouTube channels that I subscribe to. Thank goodness for Elf YouTube. It is so nice to be able to get the transcripts for things directly in there. Sacha: There's even a sponsor block integration so you can skip all the promotions and stuff. Ben: Yeah, I mean, so again, my use of YouTube is also deviant in that I pretty much strictly subscribe to RSS feeds and they're downloaded onto the file server. So when a new recording comes out, it gets dropped there. I'll watch it. And then I've got a little widget that scans through my Kodi database for watched files. Once YouTube files show up in the watch list, they're automatically purged. And it means I just never see an ad. It's not just satisfying. I don't think that I would be able to pay attention if I was being constantly interrupted because of the way that my brain works. But yeah, so being able to quickly search for YouTube is one thing. I do have... articles that I've marked as spoilers for media that I haven't watched or read yet. Maybe I go to an extreme degree, but I'll try to avoid previews for new movies, for example. But I do want to actually go back to them later on. Marking articles as having spoilers that I want to revisit later on is an easy way of not having to worry about it anymore. And for a while, back in the days when I was paying more attention to... Enter the Dragon was the sequel to... What was that TV show? The George R.R. Martin seven seasons and it went badly off the rails in season six. Sacha: Game of Thrones. Ben: Thank you. So when I was watching that for a while, several of the sites that I was reading would have individual episode updates. And I really appreciated having a list of Elfie keywords that I could automatically apply those tags to. So I wouldn't even see the headlines because it was problematic enough. I've become less... Nice. Yeah, I've been putting less effort into maintaining that now, but the infrastructure is still there and I can lean on it if I need to. One of the things that I don't have set up right now is a quick search for the municipal topics that I cover. So I tend to subscribe to a lot of news because I found that, for example, it's interesting to see how the Toronto Star covers stuff differently from other local newspapers. And it's useful to be able to quickly pull up You know, the five or six publications that cover news in the same way and then look through the annotations for them or add the annotations myself so I can see that this particular story was covered by this journalist in this publication in this way and then it lets me cross-reference so that I can pay attention to Topics that are under-covered or publications that habitually leave out particular aspects of news stories. It lets me pay more attention to The trends of publications as well as to the stories that they're covering. But the consequence of that is that my LFE database is like four and a half gigs. And it's common for me, actually, I don't know if that actually shows. It's common for me to have like 65,000 articles in like the six month horizon for the default LFE searches. And that means that searches and redraws are expensive, even on a relatively performant machine. So you've probably seen some of the workarounds that I've got. And this little bookmark selector is one of those workarounds. So L feeds interactive search, super, super useful. But if you're trying to do it like this, actually, it's not so bad. Sacha: I love this. This is like, yeah. When you see someone using elfeed for like 65,000 items, you get a sense of what you can be used for when you're really stressing it. Ben: Yeah. Well, and the organization of the bookmarks that I have means that I do have like one just river of news of all of the things that I want to pay attention to. But like it's seven or eight like pretty divergent topics with not a lot of overlap. So it's neat to be able to Think of elfeed as the thing where news information comes in, but the individual bookmarks are the topics that are grouped together that I actually care about and want to read about in concert with each other. If I specifically narrow it down to just Emacs stuff, one of the things that I can easily do is I had a bookmark for that search and if I name it. So now that I've got that bookmark saved. Sacha: And then it's like bookmark annotation. right and like this is also it ends up in my dot file so as a git config as a as a git commit but 53:13 Bookmark naming conventions
Sacha: now that that bookmark exists simply because of the naming uh lfe search now it shows up in completion precisely this sort of stuff I I am under utilizing bookmarks I think but I like that I love this idea of using bookmarks with a naming convention and then writing Emacs list but take advantage of that naming convention to make that easy to jump to easy to use in other things Ben: Yeah, it means I don't really have, like, when I notice that there's a thing, I don't have, it diminishes the activation energy for building a new workflow. It means that I don't have to put a lot of thought into it. I can quickly do it. And if it turns out to not be useful, I can quickly get rid of it. Sacha: Very cool. 53:50 elfeed-curate for annotations
Sacha: I had one more thing that I wanted to ask you about elfeed that I want to squeeze in in the five minutes that I have before the kiddo comes out for lunch break. This elfeed curate that you're using, this is the first time I've come across it in the config. Are you sharing your notes or your selections with other people or just for yourself? Ben: No. So it's just for myself sometimes. So what I'm trying to replicate is back in Google Reader days, I really appreciated how when you added an annotation to an article that you were reading, By default, that annotation would be viewable by other people in your social graph. That was super interesting. Sometimes you could also add personal-only annotations. Actually, I don't think that's the keyword that it uses. I think it's just an. Sacha: Also, because you have an Emacs keyword on it, so I don't know whether you have any annotated Emacs ones. Ben: Yeah. Well, I mean, generally, if I've added an annotation, it will be. So, for example, here. Right? Super useful. Well, super useful for me, anyhow. If I find that there's an annotation that is more... This is inflammatory. It doesn't need to go out on the web. Sacha: Sorry, you need to kill the stream and have a 10-second video. Ben: No, it's all good. I'm not worried about sharing this, but it's not something I've posted. But what the nice thing is is that if it is something that I want to share, it's really, really easy to just drop this into master.mode. Sacha: Yeah, yeah. Huh. Very cool. Ben: Yeah, so that's one of the ways that I use it. And because the annotations are just Org Mode files, you can add links to other things and it becomes just as useful as anything else. 55:46 mytoots archives Mastodon toots
Sacha: And you're saying this can flow into Mastodon and from there, once you toot it, I think you're using, like, this is mytoots thing that you mentioned in your config also for archiving it? Or searching, yeah, okay. Oh, except it's currently not working. Ben: Yeah, I don't have it loaded right now. But yeah, so mytoots, it just loads the backup of your export archive. So it loads the... What's the most recent one? So yeah, it was your Outbox JSON file, which is the most recent one here. So I've got an Org Mode reminder to download it roughly quarterly. My Outbox is about 100 megs right now. And compared to, well, I mean, it's compared to 4.5 gigs for elfeed. It's not so big. I think... Oh yeah, that's not going to redraw properly. I was just going to show it like my resident Emacs memory size right now is about like five or six gigs. It's a little bit embarrassing. By comparison, 100 megs of JSON and RAM is not so bad, but like having an instant search for everything that you posted and being able to bounce back from your local archive to the conversation thread that's live and see anything new that comes in. Again, it lets me exercise that outboard brain kind of idea. So yeah, my toot's super useful. 57:05 Mentoring offer
Sacha: I like it a lot. And then the last thing that I want to ask before, again, kiddo, because I have like two minutes, is that you have a mentoring offer pinned in your Mastodon, too. Have people taken you up on it, especially if they've taken you up on Emacs? Is that ongoing or forgotten about or whatever? Ben: Not forgotten about. Very much real. Still open. I haven't refreshed that offer recently, but it's still pinned for a reason. Yeah, I think maybe a dozen or so folks have asked for that. 9 or 10 success stories, I think. Nobody's asked for Emacs tutorialship yet. That's fine. Again, I love Emacs. I use it. I don't often recommend it. But if anybody was curious about that, I would be very open to the idea. Sacha: All right, so if people want to also develop a very interesting elfeed setup, they know who to talk to. Ben: Please, I would love that conversation. Sacha: Thank you so much. Yes, go ahead. 58:02 A local instance of public-inbox can let you use Gnus to read mailing lists quickly
Ben: Oh yeah, there's just one last thing I want to mention, and I realize we're right up against time. I use GNU for email, but I use GNU for reading mailing lists. I just wanted to just strongly recommend to anybody who is thinking about it, this is amazing. You gotta do this. Public inbox lets you keep a complete local archive of the entire mailing list. Searches are instant. Tracking threads is instant. Check it out. It's fantastic. Sacha: That's great because like Emacs develops like gazillion threads and how do you even keep track of all this stuff but if you've got news and you and if you've got this set up then you're no longer dependent on the good graces of Gmail being around as a kind of NNTP to mailing list gateway so uh so yeah uh John wants to know if you have YouTube like if you have a YouTube channel I'm guessing you don't yet but uh again I don't really like my face very much Ping Ben on Mastodon and ask about this mentoring thing and then share your notes so we can all learn from it. Thank you so much for today. I look forward to chatting with you more through toots. What is the verb, you know, in the 30-verse? All right. Thank you so much. All right. Bye. Okay, folks. I'll end the stream too. Bye. Thanks for hanging out.You can e-mail me at sacha@sachachua.com.
