Hello and happy Honda-days, Toyota-thon, etc.!

It's the tail end of winter break here, and we did a little traveling to see family, etc.. But I've been keeping the calendar light so that I have plenty of time for projects. There are too many in the works simultaneously, which is a bad sign, but during break I made significant progress on all of them. I also added a new one, with the idea that it would be a "small hack" so that I'd be sure to have something for SIGBOVIK (not everything needs to be epic, right?). It already works, but now I'm in the midst of writing a PDF file generator, which is also a bad sign.

Now that I'm nearly done going in and out of my attic so much, it seemed like good timing to attend to the dangerously acrobatic way that I always get in, which is to stand at the very top of a ladder and then mantle up using the floor joists. It's not actually that dangerous even though the ladder demands that you Never Stand Above This Line (how am I supposed to stand in the attic then, ladder?!), but I regularly lose my phone out of my pocket in the last leg-swinging step, which is at least dangerous to the phone. Without belaboring the tale, I ended up "having" to go to Harbor Freight to invest in some suspiciously cheap tools like a set of black pipe threading dies, pipe wrenches, pipe cutter, and while I was there I got a new vise. Worried that the vise would be too easy to install, I wisely purchased carriage bolts with square necks, so I had to file down the mounting holes of this thing:

JPEG File

This provided a good occasion to listen to some albums in the basement and order some new files. It is now very firmly and satisfyingly bolted to that satisfyingly timeworn workbench. Not pictured is how I needed to grind down the bolts so that the cabinet door below could open and close again (I use this cabinet to store old vises).


Codename: Viseman

The only thing I have used the new vise for so far is to flatten one of the washers that was used to attach the old, crappy vise, so that I could weld that washer to the charging terminal on my Roomba so that it's able to charge again, so that I could vacuum up all the steel filings on my basement floor. Anyway, getting back now to the original task of making the entrance to the attic a similar amount of athletic but less fraught, I installed this pull-up bar:


workout

The only hard part of this was getting the pipe to be just the right length, and threaded, but I am now equipped to do such tasks.

Winter is also a time for hibernation. I played through The Talos Principle II. I really loved the first Talos Principle, which had no business being as good as it was (the team was mainly known for Serious Sam, an over-the-top first-person shooter). Talos is a puzzle game with a pretty interesting story and fairly thoughtful writing. The sequel is good and definitely worth playing if you liked the original. It has a bit of the "Portal 2" effect where they clearly had a bigger budget and wanted to add all this polish, but did miss some of what made the original magic along the way. As you know I love to play games "the wrong way," and so I'm always looking for ways to break the puzzles in this game. I felt like the first one let me get away with more hijinks, like you'd stack items to make your way up somewhere, and a third of the time it'd be a Star (expected for 100%), a third of the time it'd be an Easter egg (acknowledging your prowess), and a third of the time you'd just fall out of the map forever and have to reset (true victory). I did fall out of the level several times on this sequel, but it seemed to me that the puzzles were more tightly constrained. Then again, I watched the current world record speedruns and there's certainly a lot of hijinks possible, so maybe I'm just losing my edge! I also played through Party Hard. It's a "murder all the people in 2D" game very similar to the Hotline Miami games, and not as good, but its absurd mood and unfair chaotic difficulty did grow on me. Right now I am "playing" (the) Gnorp Apologue, an idle game that has its charms, but, well, it's an idle game and I think it is cruel to ever recommend those. It was written in Rust!

So what? We went to Mexico for vacation, visiting the island of Cozumel and some nameless resort area between Cancún and Playa del Carmen. This was just a vacation, for relaxing, so I spent most of the time programming for fun or writing my SIGBOVIK paper, but with a nice view of the ocean and a little bit of sand in my keyboard, and a little bit of mediocre Mexican beer. Cozumel was a pretty neat place: We happened to be there for the 150th year of their Carnival, which was happening concurrently with the Super Bowl, so there was a wild collision of tourist "culture" and local culture one evening. I added a picture to the Wikipedia article. It's a sparsely populated island, small enough to bike pretty much the whole way around, although as the bike rental guy informed us, "most people leave in the morning." We did some caving and won some bingo games and did some moderate to severe food poisoning, and now I'm back!

So what else? I'm deep into my project now and the end is (sort of?) in sight, but time is running short and I keep adding unnecessary aspects to it. It's fine. Even though I feel some pressure to keep making these elaborate projects, for deadlines, the real point of my hobby is for me to enjoy the spirit of the hack, which sometimes just means reimplementing typed closure conversion for the nth time.

Oh! I will be presenting at An Evening of Unnecessary Detail in Brooklyn on April 14. I have a silly style of beard again so that you can tell me apart from Matt Parker (aside from his very different accent and he's much taller than me and says it as "maths" and actually doesn't even really look like me now that I'm looking at a picture again). I think this will be quite fun.

I've been playing trough Super Monkey Ball Banana Mania, which like Katamari Damacy I had played some of ~20 years ago and had always wanted to finish. I do love struggling with a precision platformer, though as usual with 3D ones the analogueness and camera trouble can be a bit of a drag. It's a good game with a good flow, though, and I'm like 80% of the way through it at this point. And speaking of 3D precision platformers, Celeste 64 is a cute 3Dification of Celeste (which remains one of my all-time favorites in the precision platformer genre) that they released for free recently. Initially I found this game really frustrating; it doesn't have nearly the same attention to detail in the controls that the 2D game does. But by the time I finished it, the controls and camera no longer seemed disastrous to me, and I pretty much liked it. On the other end of the spectrum, I for some reason bought "Yeah! You Want "Those Games," Right? So Here You Go! Now, Let's See You Clear Them!" and then for some reason beat every level of it. This game is an in-depth implementation of some notorious "games" featured in Mobile Game Hell-type advertisements. (If you're not aware of this phenomenon, it's common for the advertisement to depict some kind of casual gameplay that looks kinda fun, but that if you download the app it's linked to, it's like some totally different game like Clash Of Clans or something like that. So there are all these fairly recognizable games that you can't actually play. Bizarre! I'm guessing that there's just a market for "just get us downloads of the app" where they literally don't even care what the content of the advertisement is.) Anyway, this long-titled game is an implementation of some of those, with like hundreds of levels. Honestly I can't tell how ironic it is, but I did appreciate it as artwork even though it was also basically torture. I recommend it if you are my enemy, or if you like is-it-art?-torture. Having finished that and immediately deleted it, I just started Teardown, which I like so far, but I haven't gotten into it enough to provide a full take.

In a fashion that's thematically appropriate for the project, I'm "taking my time" with this video (e.g. I am still writing new code for it today??). It mostly means that I feel behind a lot. But I think I am truly close now to being done. I got all my new gear working together, 3D-printing rig pieces and so on. This has been generally fun. I'm also enjoying the occasion to experiment with new approaches and video editing techniques. I even cleaned out a significant section of my basement for a temporary studio:

Green scream

I think I have about 120 seconds of finished video here, which is far worse than my usual bad pace of about an hour a minute. Fortunately the rest should be much more straightforward, and I hope to just record the audio and be done with it this weekend. Pro tip, though: Don't install the new version of Adobe Premiere Pro while you're knee-deep in a complicated edit. Why would you press that button?

My procrastination: I fully beat Teardown and all the stakes in Balatro (but I may try to finish the last few challenges). Both good games, recommended. For light procrastination I have been playing Grapple Dog which has cute graphics and writing and is getting better as the levels get more challenging, but I probably wouldn't fully recommend. It's a stage-by-stage linear platformer with three irritations: The controls are a little too "snap-to-nearest" (like you will often initiate an unwelcome wall jump just because you jump near a wall) for me, the music is annoying, and I really want to get all the purple gems, but I can never tell whether I'm going the "right" way or the "wrong" way, and so I will often miss them just because of that. But I do basically like the game. I also started, for procrastination purposes, Humanity, which was recommended to me a while ago. It is good. The Steam videos do not do justice to how slick the game's graphics are (especially the UI has all these fluid little touches and impressive continuity as you transition between levels); I think it needs to run on a big monitor with a high frame rate. At its core it's mostly a puzzle game, with many things you have seen before, but also some new clever stuff (and I am only on the 2nd world, so I presume they have more surprises in store for me).

I believe this is all.

This is not a political blog, although politics inevitably creep in to discussions of matters legal. I have followed politics since I was at school, although I was never elected to anything. The current situation beggars belief, and I imagine that today's crop of journalists will shake their heads in their old age, and say "but you should have been there in the summer of 2016; everything seemed to happen at once. " I am now even more convinced that my belief in the iron Law of Unintended consequences is the right one.

I have had to cut back on my sittings of late, as I am awaiting an operation to give me a new knee joint, and although I can get around in the courthouse it isn't always easy. As I am due to retire from the Bench in late October I have excused myself from getting to grips with some of the more complex innovations that have recently been introduced, such as iPads on the bench. I own a couple of iPads and I am comfortable with using them, but inevitably any government-issued software is over-engineered and the last thing from user-friendly.

My court has a few boxes that contain the iPads as well as charging them overnight, but those JPs who wish to use them have to submit to training as well as an elaborate procedure to keep them secure. It is worse for judges of course, but then they are paid £130k and more to cope.

Given my impending retirement, I cannot summon up the enthusiasm to get stuck in to this 21st century stuff  (albeit the technology is a decade old).

I am trying to avoid becoming what old Army types call demob-happy so I shall concentrate on justice before bureaucracy.

As of November 10, 2015, BORROWED TIME (the sequel to CHRONAL ENGINE) is now available in bookstores everywhere as well as online (in hardcover and ebook)!  Signed copies are available from BookPeople.

In an article titled, 'Borrowed Time' mixes paleontology and fantasy, Saturday's Austin American-Statesman had a great review of BORROWED TIME, stating it's "a slam-dunk for dinosaur aficionados and will appeal as well to those who are fans of literary time travel and outdoorsy adventure."

Sunday was the launch party at BookPeople! I had great fun doing a presentation discussing the connections between the book, Charles Umlauf, dinosaurs, Johnny Weissmuller, and me (really).

The dinosaur standees for the photo booth were a hit, as were the refreshments including water, soft drinks, wine and cheese, and crackers. (The wine, from the Languedoc region of France, is made from grapes grown in Cretaceous clays where dinosaur fossils have have been found).

But the real eye-opener was the mosasaur cake by author/cakelustrator Akiko White. About two feet high, it featured a mosasaur sculpted from modeler's chocolate on a chocolate cake base with buttercream frosting! She'll be doing a youtube video on the making of it soon (and I'll link when it's available).  Suffice to say that still pictures don't do it justice -- it was mounted on a motorized turntable and illuminated with a blue strobe that made it look like it was underwater!

Here are the pics:

AVENGED, by Amy Tintera (HarperTeen, May 2018).

Jupiter has often been thought to protect the inner Solar System from asteroids and comets, but new research has shown that the giant planet may actually increase the risk of an impact.

From X-ray imaging to slithering beneath Enceladus’ crust, space technology is always expanding what we can see for ourselves.

The tentative discovery hints at an habitat where life could potentially thrive.

The habitable zone is a useful concept in astrobiology, but it can sometimes paint an over-simplified picture of planetary habitability.

From holes on Mars to a spun-around moon and a flipped reflection, space science involves looking at things from all different angles.

Looking at life on Earth from another perspective.

It’s been a great year for space exploration. Now you get to pick the highlights.

Sneak peek — tray, citrus chess board, serving board.

I have an idea of making a few stands of Draugr, the Viking dead. I have bought some nice Colin Pattern sculpts but thought I'd have a go at making some.
I have loads of Viking sprues left over from the Lake town project, these I mixed with some Oathmark undead sprues. I will add some greenstuff to these to make them a little more Viking.


 

I'm a sucker for sage advice much as anyone else, and Kernighan is certainly right on money in the epigraph. Alas there comes a time in programmer's career when you just end up there despite the warning. It could be that you were indeed too clever for your own good, or maybe the code isn't quite yours anymore after each of your colleague's take on it over the years. Or just sometimes, the problem is indeed so hard that it strains your capacity as a coder.

It would usually start with a reasonable idea made into first iteration code. The solution looks fundamentally sound but then as you explore the problem space further it begins to seep nuance, either as manifestation of some real world complexity or your lack of foresight. When I run into this my first instinct is to instrument the code. If the problem is formidable you got to respect it: flailing around blindly modifying things or ugh, doing a rewrite at this stage is almost guaranteed to be a waste of time. It helps to find a promising spot, chisel it, gain a foothold in the problem, and repeat until you crack it. Comfortable debugging tools here can really help to erode the original Kernighan coefficient from 2 to maybe 1.6 or 1.4 where you can still have a chance.

Lisp users are fortunate with the options of interactive debugging, and one facility I reach often for is the plain BREAK. It's easy enough to wrap it into a conditional for particular matches you want to debug. However sometimes you want it to trigger after a particular sequence of events across different positions in code has taken place. While still doable it quickly becomes cumbersome and this state machine starts to occupy too much mental space which is already scarce. So one day, partly as a displacement activity from being intimidated by a Really Hard Problem I wrote down my debugging patterns as a handful of macros.

Enter BRAKE. Its features reflect my personal preferences so are not necessarily your cup of tea but it could be a starting point to explore in this direction. Things it can do:

• act as a simple BREAK with no arguments (duh)
• wrap an s-expression, passing through its values upon continuing
• trigger sequentially based on the specified position for a common tag
• allow for marks that don't trigger the break but mark the position as reached
• provide conditional versions for the expressions above
• print traces of tagged breakpoints/marks

If you compile functions with debug on you hopefully should be able to see the wrapped sexpr's result values.

(use-package '(brake))

(defun fizzbuzz ()
  (loop for n from 100 downto 0
	for fizz = (zerop (mod n 3))
	for buzz = (zerop (mod n 5)) do
	(format t "~a "
		(if (not (or fizz buzz))
		    (format nil "~d" n)
		  (brake-when (= n 0)
			      (concatenate 'string
					   (if fizz "Fizz" "")
					   (if buzz "Buzz" "")))))))

These macros try to detect common cases for tagged sequences being either aborted via break or completed to the last step, resetting them after to the initial state. However it is possible for a sequence to end up "abandoned", which can be cleaned up by a manual command.

Say in the example below we want to break when the two first branches were triggered in a specific order. The sequence of 1, 3, 4 will reinitialize once the state 4 is reached, allowing to trigger continuously. At the same time if we blow our stack it should reset to initial when aborting.

(defun ack (m n)
  (cond ((zerop m) (mark :ack 3 (1+ n)))
        ((zerop n) (mark :ack 1 (ack (1- m) 1)))
        (t (brake :ack 4 (ack (1- m) (ack m (1- n)))))))

In addition there are a few utility functions to report on the state of brakepoints, enable or disable brakes based on tags and turn tracing on or off. Tracing isn't meant to replace the semantics of TRACE but to provide a souped up version of debug by print statements everyone loves.

CL-USER> (report-brakes)
Tag :M is DISABLED, traced, with 3 defined steps, current state is initial
Tag :F is DISABLED with 2 defined steps, current state is 0
Tag :ACK is ENABLED with 3 defined steps, current state is initial

Disabling breakpoints without recompilation is really handy and something I find using all the time. The ability to wrap a sexpr was often sorely missed when using BREAK in constructs without implicit body.

Sequencing across threads is sketchy as the code isn't guarded but in many cases it can work, and the appeal of it in debugging races is clear. One of those days I hope to make it more robust while avoiding potential deadlocks but it isn't there yet. Where it already shines tho is in debugging complex iterations, mutually recursive functions and state machines.

I am always happiest when a story of mine comes into print. Today, I have the joy of introducing you to "Unquiet Graves," a seasonal tale of graveyard misbehavior and betrayal. Oh, and there's nothing supernatural about it at all.

You can read the story here. But if you're like me, you'll just go to Clarkesworld, look over the table of contents, and decide which story you want to read first. Mine by preference, but follow your whim.

 

And for those who like trivia . . .

I came up with the handheld's app many long years ago and it took forever to come up with a story for it. You'll notice that it is left unnamed in the story. That's because its secret name was "The Graveyard Reader." Which is the title of a well-known story by Theodore Sturgeon.  While I was writing the story, I thought of it as "The New Graveyard Reader." But Sturgeon's story and mine go off in totally different directions, and giving mine (or even the app) a title suggesting there was some implicit connection between the two would only cause confusion.

The title I finally came up with was derived from "The Unquiet Grave" by that most prolific of all poets, Anonymous. If you look it up, I suggest you do so after reading my story. It gives away some of the plot.

This year's Halloween story, written on leaves and serialized daily on my blog, one sentence at a time, is done. Every day in October, I added to it, it reached its last words on Halloween.

Funny thing, though. In conversations with two different friends, I learned that neither of them had realized it was a story. They each thought I was just posting random sentences written on leaves. One of them is an artist, and thinks primarily in visual terms, so I thought at first that was a misunderstanding curious to her. The other, however, is a well-known writer and, what's more important, quite a good one. I have no idea what's going on there.

Long story short, at my behest, my son Sean, put all the photos up on Imgur, subtitled. So, if you didn't realize that they told a story... Or if, somehow, you weren't able to hold all the sentences in your head until the story was complete... Now you can find out what was going on. (The stone angels mark the ends of paragraphs.)

You can find it by clicking on the link here.

Leaf-writing season is over. By a small coincidence, a leaf has surfaced on the nightstand by my bed. I have a vague memory of writing this, but the date I'd written on it is gone, along much of my name. 

It reads:

               The leaf came in the mail with a message:

               "Preserve Me and I'll Preserve Thee."

                Some obeyed and prospered. Some

                did not and were not.

I am of two minds on this. One says it wouldn't hurt and might help to preserve it. The other says that I should never give in to a superstition I have coined myself.
