    I am a fairly sanguine UK rail commuter. I do not understand why they schedule the annual price hike for exactly the same week the holiday maintenance work is likely to have overrun, affecting all the services. Surely it would make more sense to raise the price at the start of the financial year, in April?

    Old Street station has a popup "Black Mirror" shop. I am not sure how I feel about this. I am fairly sure I know how Dan Ashcroft would feel about this.

    And just like that we're back. What happened cms?

    It was never entirely my intention to go offline for such an extended hiatus. Even though the web is intrinsically brittle and ephemeral, I like to do my bit to keep my little backwater serving 200 OK s to the half-dozen people who stop by to check in regularly, and the couple of dozen who linked to something I put up at some point. It's basic web-citizenship as far as I'm concerned.

    Before we went fully dark, I'd not posted for a long time already . And before that I'd slowed my posting down to something of a crawl. I think there's a few reasons for that. It's easy to get bored with blogging for the sake of blogging, especially in our current age where everyone shares profligately across many social platforms . It's fairly common to see blogs that have fallen into a recursion of no posts for months, then a post apologising about that, and then further disuse. I don't think this is one of those, but the proof is in the posting I suppose.

    There's certainly been less time in real life for auxilliary pursuits like online rambling, and that's a big part of the reason. No time for any proper content posts, concomitant with a surge of alternative social platforms to play around with, meant it often seemed a bit redundant to post arrays of short-links , when I could just throw them up on twitter / adn / diaspora* / flickr / ello / imzy /whatever, with a bigger audience, and more interaction.

    I was also feeling a bit self-conscious about standing up in public. After leaving last.fm (fairly amicably, as these things go, fwiw, albeit with a slightly battered heart), which felt like a fairly visible shift sideways, I was quite deliberately courting more obscure, maybe more unexpected job roles, and I remember feeling like I really didn't want to bare my thoughts to the internet judgement machine whilst I wasn't even entirely sure what I was doing myself a good deal of the time. Also busy! Young family plus startups really left little time for anything much else.

    I also was really feeling the pain of Wordpress . I never quite managed to find an authoring approach to use with it that didn't make writing anything seem like far harder work than it ought to be, also because I always insist on self-hosting, the sheer weight of it for maintainence and security updates, and backups, and DBA -ing, and having to write PHP or perhaps even plugins to do the inevitable customisations someone like myself inevitably finds themselves suckered into doing. So Wordpress was a drag, which was feeding my reluctance to contribute much of substance. So I decided to pause on updating whilst, in true wannabe-hacker style, I whipped together some kind of alternative content publishing system.

    I'll just take a paragraph out to stress that I actually admire WordPress a great deal. It's a very sophisticated and flexible web platform, and a great choice for site management, in either managed or self-hosted configuration. It kept this site ticking along for years. It just isn't a particularly good fit for my requirements, which are extremely simple

    I thought about using another off-the-shelf blogging system, which would have been the sensible route, but I figured that would just lead to a similar frustrated stalemate. So I started to sketch out an application that would allow me to quickly fling out tagged and dated content without much overhead of hosting or writing. And I carried on intermittantly piecing this app together, often on trains, for a couple of years. As an exercise in procrastination, it worked out better than I expected, and I carried on posting short content to twitter and others, reasonably happy to continue to defer the responsibility.

    But then the site went dark. I was hosting it all on a linode instance. I've been a very enthusiastic linode user for perhaps ten or more years, I think they have an excellent product, offering well-provisioned VPS instances , inexpensively, with an easy to use management site. Generally I've been very happy with them to date.

    This changed somewhat last year, and my confidence deflated a little. There was an extended outage of service across linode in December 2015 , apparently as a result of a targetted DDOS . This lasted for many days, and the communications about it from linode were muted and suspiciously vague. This isn't really what I expect from a first-tier ISP. I came away with the impressions that there were some significant architectural problems with their infrastructure, probably from acrued technical debt , and potentially some exploitable vulnerabilities in their public facing application software . I decided it was time for a change.

    I did some reasearch and rented a couple of new hosts. This time I've gone for low end, physical servers. This represented another procrastination opportunity, because when I originally set up the beatworm.co.uk linodes, almost ten years ago, I just hand configured everything by remote shell. Now I like to use the ansible configuration management system to set up hosts, and I took this opportunity to port my public infrastructure across to use repeatable playbooks. This turned into another major yak-shave , because there was slightly more to it than just a WordPress deployment, I was hosting mail, calendars, media streaming, IM, DNS, the works. After getting lost in this tarpit for a couple of months, I decided to move the application tier over to use the playbooks from the sovereign project , which covers much of the same ground, but is already written, and uses more modern components. Of course it wasn't entirely straightforward to integrate these plays over my existing base provisioning, and I ran into a couple of glitches and gotchas with some of the choices they'd made for configuration, but it only took a couple of weekends worth of fiddling to get it all running in a fairly acceptable shape. I moved the DNS across, at which point the wordpress site was left behind, and everything went dark.

    I was surprised at how much this bothered me.

    I like an outlet for sharing things. I enjoy the idea of having a stable internet identity . I don't like the way the modern web has folded these ideas into a handful of consumer products run by just a couple of corporate gatekeepers. That's not the web I grew up with, and it's not the web I want to see either. A very loosely federated ecosystem of ad-hoc resources, all mixed together as hypermedia, aggregated and accessed via an assorted bag of user-agents. That's how it works best . I like to write, because I like the practice and discipline of working toward articulating my thoughts for a general reader.

    I like being able to curate an archive, and keep control over how that information persists and is presented. This is hard enough to do when you have primary jurisdiction over the medium and material (there is plenty of bitrot on view in my archive, particularly in the really old material, which has been migrated across multiple publishing platforms now), and basically impossible if you're relying on a third party service, which periodically re-invents itself to better serve it's own objectives, which are only ever to be tangentally aligned with your own, at best.

    I don't like the sense of obligation I get from formal social media platforms. There's a subliminal sense of pressure to perform, to update, to observe the conventions, to consider and measure the implied audience. I'm not a joiner by nature. I just end up gently resenting the throng. I like to feel like I have a voice, but I don't want, or even expect to reach, an automatically provided audience.

    So, I picked back up my now-neglected website platform experiment, and knocked it together enough to get an MVP out of the door. It serves HTML over HTTP. It has a relatively minimal set of style rules that should allow it to work gracefully across various screen dimensions. It has rudimentary support for RSS ( not that many people use newsreaders any more ). It's simple to run in a staging environment, and I can write posts in plain text in emacs , and edit and post them without much extra grief. It's only got about 22% of the functionality I had originally planned, but I feel the urge to ship it, use it, and hopefully I'll refine it in production.

    There's a couple of interesting quirks to this new hosting setup. It's an ARM -based micro-blade, hosted on a scaleways C1 . The blogging software is semi-static , in as much as it serves generated content from the filesystem. It's written in common lisp , and deployed in a different lisp to the one it's developed on There's no frameworks (aside from using zurb foundation classes to base the CSS). There's no database. There's no comments, because I haven't yet decided on a productive way to support them.

    I've been writing a couple of things in hy again this week. What's Hy? It's a cute idea. It's a lisp that compiles? (transpiles? I never get the difference) to the Python AST. I guess the elevator pitch might be something like clojure but for python. So yeah, a rich, super stable class-tree sort of OO language, with enormous portablility and twenty-odd years of library support for everything you might want to do, but with a nice, dynamic, lispy language and a repl.

    I've played with hy a little bit on and off over the years. Actually, when I was working at SMR, I actually deployed some in production. (Somehow, I doubt that's still a thing). Python is my go-to scripting language, because it's very plain, very portable, batteries included, somewhat modern, probably already installed everywhere I work. I try to use it for scripty things, rather than shell or perl or something. Lisps are my favourite programming language. I just like how it fits together. I know lots of people don't, and I'm fine with that, but I always enjoy it.

    So over the holiday weekend I found myself wanting a couple of almost throwaway scripts, and I decided to reach back into the hy bucket, and give that another try. I wrote a script to grab my selfie tweets from a twitter archive, and a rough script to publish formatted micro-blog entries directly from the shell.

    It was a fun exercise. Hy has moved on a bit since I last tried. (They seem to have removed let, and car, and cdr, and lambda which I feel funny about), but by and large it works really well.

    Things I like

    • I like mapping over lists of things, and in straight Python this is often clumsy and leads to densely nested comprehensions
    • actual lambdas!
    • Python3 support ( hy3 )
    • easy importing of python modules
    • mostly seamless python interop
    • repl works great
    • the repl shows you the pythonic syntax of the forms it evaluates, which is helpful if you know Python
    • emacs mode (obv)
    • it has lazy sequences
    • and multimethods!
    • it is fun to work in

    Things I like less

    • Missing some olde lisp things like car/cdr/lambda
    • Things often expect you to be using methods on stateful objects, which gets you an OO impedance mismatch (I have the same problems in scala and clojure)
    • Slightly more typed than you expect, whilst not really offering you a type system. (Particularly with distinctions between lists, sequences, iterators.)
    • it often seems easier to imperative loop with for than map / reduce / filters, and this seems weird.
    • i don't feel I have any understanding about setv variable scoping.
    • no STM, which I think is one of the most interesting things about clojure
    • I don't think the error handling does restarts and conditions and things

    Summary

    I don't think I would choose to use it to build any complicated systems. (Typically this is true of Python as well to be fair). I'd love to see something like an idomatic web framework in it. I could imagine using it to build serverless workers over something like apex up or chalice perhaps. I should totally try that!

    I am not really very good at it yet, so I doubt I'm writing optimal programs. My scripts often look like Dr. Moreau designs halfway between a python script and something more lispy. This could well improve as I understand the underlying sequence / itertools glue a bit more, I'm often routing around confusing sequenced things. I absolutely enjoy writing little scripts like this in it, and I think I maybe enjoy it more than I would if I was writing plain python. I gave some thought about why this might be and I think I figured it out.

    It could just be as simple as being all about the code editing. Python, and it's whitespace delimited blocks, is fine, and super readable, but it's always slightly fiddly to edit. Some of this is my toolchain, I'm sure. There's a lot of bells and whistles you can glue over emacs for Python work, and they're pretty good, but I do always find it a slightly fiddly experience. Balanced expressions and sexprs though are obviously an absolute joy to edit in emacs, alongside an embedded inferior lisp repl, and although it's nowhere near as integrated an experience as using slime with a "real" lisp, it's closer to that than editing Python ever feels, and for me that's a significant productivity win. So I think it will stay in the toolbox.

    I recommend Hy to anyone who is interested in interesting lightweight languages, especially scripting languages. Obviously it's particularly relevant to anyone who likes python or lisps, even if just as a curiosity. If you work with Python and like using emacs though, and like the sound of 'Python but with structured editing' I would strongly recommend you look at how it might integrate into your workflow.

    I already mentioned in passing, St. Vincent , the band-shaped solo project brand thing of the super-engaging Annie Clark, was by far the best act I saw at Primavera Sound 2014. It was also the act I was most looking forward to seeing going in, it’s always nice when those line up.


    I guess I’m a super-fan. I first spotted Annie playing with Sufjan Stevens ' touring band. I next encountered her playing solo support for the National , touring her first St. Vincent release , upon which occasion I bolted out of the auditorium by the third song, in order to make sure I got a copy of the CD she was plugging from the merch stall before she packed away. I saw another couple of shows in Bristol, with the full band, and bought all the records, including an interesting collaboration with David Byrne .


    Last weekend, while idly browsing the Glastonbury live blog, I noticed that they’d just updated their description of the current iPlayer feeds to include St. Vincent streaming on the iPlayer from the park stage. I’d been avoiding the Glastonbury video feeds due to a combination of not being in the mood, and the dullness of the tv schedules, but I wasn’t going to miss out on this, so I whacked it on the TV. True to form, it was a great set, live, risky, and peppered with amusing crowd-surfing and hat theft . Even with a bit of sound problem, and some streaming glitches I enjoyed myself, and was amused to see my enthusiastic tweeting duly included in the Guardian live feed on the next page refresh.


    “ That was a really good set ”, I thought to myself, afterwards, “ but it wasn’t nearly as exciting as the Barcelona one. True, that lacked crowd invasions, and nobody lost a hat, but the lighting, and the sound, and the staging, and the lack of daylight, and the crowd being really into it…A pity there’s no TV-broadcast quality stream of that night archived away somewhere ”. 


    Yes, I do really talk to myself like that sometimes. Especially when I’m pretending to transcribe my inner voice for a blog.


    And then, I ran into this on Youtube.


     


    Full set, multiple cameras, properly mixed sound, pretty good video quality. I have not yet watched it enough times to see if I can see myself ( front of house, stage left, VIP pen ) in the crowd, but I expect I will.
