Better Identification of Viking Corpses Reveals: Half of the Warriors Were Female insists an article at tor.com. It’s complete bullshit.
What you find when you read the linked article is an obvious, though as it turns out a superficial problem. The linked research doesn’t say what the article claims. What it establishes is that a hair less than half of Viking migrants were female, which is no surprise to anyone who’s been paying attention. The leap from that to “half the warriors were female” is unjustified and quite large.
There’s a deeper problem the article is trying to ignore or gaslight out of existence: reality is, at least where pre-gunpowder weapons are involved, viciously sexist.
Yesterday I shipped cvs-fast-export 1.15, with a significant performance improvement produced by replacing a naive O(n**3) sort with a properly tuned O(n log n) version.
In ensuing discussion on G+, one of my followers there asked if I thought this was likely to produce a real performance improvement, as in small inputs the constant setup time of a cleverly tuned algorithm often dominates the nominal savings.
This is one of those cases where an intelligent question elicits knowledge you didn’t know you had. I discovered that I do believe strongly that cvs-fast-export’s workload is dominated by large repositories. The reason is a kind of adverse selection phenomenon that I think is very general to old technologies with high exit costs.
The rest of this blog post will use CVS as an example of the phenomenon, and may thus be of interest even to people who don’t specifically care about high version control systems.
Our new cat Zola, it appears, has a mysterious past. The computer that knows about the ID chip embedded under his skin thinks he’s a dog.
There’s more to the story. And it makes us think we may have misread Zola’s initial behavior. I’m torn between wishing he could tell us what he’d been through, and maybe being thankful that he can’t. Because if he could, I suspect I might experience an urge to go punch someone’s lights out that would be bad for my karma.
I just had a rather hair-raising experience with a phase-of-moon-dependent bug.
I released GPSD 3.11 this last Saturday (three days ago) to meet a deadline for a Debian freeze. Code tested ninety-six different ways, run through four different static analyzers, the whole works. Because it was a hurried release I deliberately deferred a bunch of cleanups and feature additions in my queue. Got it out on time and it’s pretty much all good – we’ve since turned up two minor build failures in two unusual feature-switch cases, and one problem with the NTP interface code that won’t affect reasonable hardware.
I’ve been having an extremely productive time since chewing through all the stuff I had deferred. New features for gpsmon, improvements for GPSes watching GLONASS birds, a nice space optimization for embedded systems, some code to prevent certain false-match cases in structured AIS Type 6 and Type 8 messages, merging some Android port tweaks, a righteous featurectomy or two. Good clean fun – and of course I was running my regression tests frequently and noting when I’d done so in my change comments.
Everything was going swimmingly until about two hours ago. Then, as I was verifying a perfectly innocent-appearing tweak to the SiRF-binary driver, the regression tests went horribly, horribly wrong. Not just the SiRF binary testloads, all of them.
Yes, I’m aware of the spam on the blog front page. The management does not hawk dubious drugs.
Daniel Franke and I just did an audit and re-secure of the blog last night, so this is a new attack. Looks like a different vector; previously the spam was edited into the posts and invisible, this time it’s only in the front-page display and visible.
It’s a fresh instance of WordPress verified against pristine sources less than 24 hours ago, all permissions checked. Accordingly, this may be a zero-day attack.
Daniel and I will tackle it later tonight after his dinner and my kung-fu class. I’ll update this post with news.
UPDATE: The initial spam has been removed. We don’t know where the hole is, though, so more may appear.
UPDATE2: It’s now about 6 hours later and spam has not reappeared. I changed my blog password for a stronger one, so one theory is that the bad guys were running a really good dictionary cracker.
Once Dead (Richard Phillips; Amazon Publishing) is a passable airport thriller with some SF elements.
Jack Gregory should have died in that alley in Calcutta. Assigned by the CIA to kill the renegade reponsible for his brother’s death, he was nearly succeeding – until local knifemen take a hand. Bleeding, stabbed and near death, he is offered a choice: die, or become host to Ananchu – an extradimensional being who has ridden the limbic systems of history’s greatest slayers.
Before you read any further, go look at the drawing accompanying the New Tork Times article on the autopsy of Michael Brown,
There’s a story in that picture. To read it, you have to be familiar with pistol shooting and the kind of pistol self-defense training that cops and amateur sheepdogs like me engage in.
In the remainder of this post I’m going to walk you through the process of extracting the story from the picture.
One of the reasons I like cats is because I find it enjoyable to try to model their thought processes by observing their behavior. They’re like furry aliens, just enough like us that a limited degree of communication (mostly emotional) is possible.
Just now I’m contemplating a recent change in the behavior of our new cat, Zola. Recent as in the last couple of days. Some kind of switch has flipped.
I join my voice to those of Rand Paul and other prominent libertarians who are reacting to the violence in Ferguson, Mo. by calling for the demilitarization of the U.S.’s police. Beyond question, the local civil police in the U.S. are too heavily armed and in many places have developed an adversarial attitude towards the civilians they serve, one that makes police overreactions and civil violence almost inevitable.
But I publish this blog in part because I think it is my duty to speak taboo and unspeakable truths. And there’s another injustice being done here: the specific assumption, common among civil libertarians, that police overreactions are being driven by institutional racism. I believe this is dangerously untrue and actually impedes effective thinking about how to prevent future outrages.
In the Kivila language of the Trobriand Islands there is a lovely word, “mokita”, which means “truth we all know but agree not to talk about”. I am about to speak some mokitas.
Unexpected Stories (Octavia Butler; Open Road Integrated Media) is a slight but revealing work; a novelette and a short story, one set in an alien ecology among photophore-skinned not-quite humans, another set in a near future barely distinguishable from her own time. The second piece (Childfinder) was originally intended for publication in Harlan Ellison’s never-completed New Wave anthology The Last Dangerous Visions; this is its first appearance.
These stories do not show Butler at her best. They are fairly transparent allegories about race and revenge of the kind that causes writers to be much caressed by the people who like political message fiction more than science fiction. The first, A Necessary Being almost manages to rise above its allegorical content into being interesting SF; the second, Childfinder, is merely angry and trite.
I shipped point releases of cvs-fast-export and reposurgeon today. Both of them are intended to fix some issues around the translation of ignore patterns in CVS and Subversion repositories. Both releases illustrate, I think, a general point about software engineering: sometimes, it’s better to punt tricky edge cases to a human than to write code that is doomed to be messy, over-complex, and a defect attractor.
The Gods of War (Graham Brown & Spencer J. Andrews; Stealth Books) is one of the better arguments for the traditional system of publishing-house gatekeepers I’ve seen recently. It is not merely bad, it is a stinkeroo that trumpets its awfulness from page one.
I just got back from the 2014 World Boardgaming Championships in Lancaster, PA. This event is the “brain” half of the split vacation my wife Cathy and I generally take every year, the “brawn” half being summer weapons camp. WBC is a solid week of tournament tracks in strategy and war games of all kinds, with a huge open pickup gaming scene as well. People fly in from all over the planet to be here – takes less effort for us as the venue is about 90 minutes straight west of where we live.
Nexus (Nicholas Wilson; Victory Editing) is the sort of thing that probably would have been unpublishable before e-books, and in this case I’m not sure whether that’s good or bad.
There’s a lot about this book that makes me unsure, beginning with whether it’s an intentional sex comedy or a work of naive self-projection by an author with a pre-adolescent’s sense of humor and a way, way overactive libido. Imagine Star Trek scripted as semi-pornographic farce with the alien-space-babes tropes turned up to 11 and you’ve about got this book.
It’s implausible verging on grotesque, but some of the dialog is pretty funny. If you dislike gross-out humor, avoid.
LSE is a wasting disease. It invades the brains of writers of SF and other genres, progressively damaging their ability to tell entertaining stories until all they can write is unpleasant gray goo fit only for consumption by lit majors. One of the principal sequelae of the disease is plunging sales.
If you are a writer or an aspiring writer, you owe it to yourself to learn the symptoms of LSE so you can seek treatment should you contract it. If you love a writer or aspiring writer, be alert for the signs; victims often fail to recognize their condition until the degeneration has passed the critical point beyond which no recovery is possible. You may have to stage an intervention.
Here are some clinical indicators of LSE:
One of the minor frustrations of my life, up to now, is that though I can sell as much nonfiction as I care to write, fiction sales had eluded me. What made this particularly irksome is that I don’t have only the usual ego reasons for wanting to succeed. I love the science fiction genre and owe it much; I want to pay that forward by contributing back to it.
It therefore gives me great satisfaction to announce that I have made my first SF sale, a short (3.5kword) piece of military SF titled Sucker Punch set on a U.S. aircraft carrier during the Taiwan Straits Action of 2037. Some details follow.
Of Bone And Thunder (Chris Evans; Pocket Books) is an object lesson in why fiction writers should avoid political allegory. Yes, it’s a fantasy reflection of the Vietnam War; on the off-hand chance a reader wouldn’t have figured it out by about page 3, the publisher helpfully spells it out in the blurb.
Traitor’s Blade (Sebastian de Castell; Jo Fletcher books) is perhaps best tescribed as a noirish fantasy spin on Dumas’s Three Musketeers. But it’s better, and less derivative, than that sounds.
Before you read the rest of this post, go look at these pictures of a Hobbit Pub and a Hobbit House. And recall the lovely Bag End sets from Peter Jackson’s LOTR movies.
I have a very powerful reaction to these buildings that, I believe, has nothing to do with having been a Tolkien fan for most of my life. In fact, some of the most Tolkien-specific details – the round doors, the dragon motifs in the pub – could be removed without attenuating that reaction a bit.
To me, they feel right. They feel like home. And I’m not entirely sure why, because I’ve never lived in such antique architecture. But I think it may have something to do with Christopher Alexander’s “Timeless Way of Building”.
