Over the last decade, Orbit US, an imprint of Hachette Book Group, has quickly established itself as one of the premiere publishers of science fiction and fantasy, and a reliable source for everything from innovative works of science fiction to blockbuster epic fantasies. To celebrate the milestone, a selection of landmark Orbit titles is currently available on Nook for just $2.99 each, but we wanted to do more than point you toward some great titles, so we asked Orbit’s publisher, Tim Holman, to share a bit of history. Below his comments, you’ll find a timeline of key dates in Orbit’s history.
My captain’s keyboard has stopped working. :}
I’m almost positive I know what the problem is. There are about 8 keys that don’t work, and there’s a pin in the PS/2 connector that got bent a while ago. I was able to nudge it back into place, but it got yanked and bent again and although I’ve nudged it back into place again, I think the base of the pin is no longer connecting.
I’m also almost positive this could be fixed by splicing a new PS/2 connector into place.
The PROBLEM is that the OTHER end of the connection is wired directly into the keyboard (of course), and the keyboard, being two unwieldy pieces, is a pain in the ass to bring anywhere. Assuming there’s even somewhere around here that would do this kind of thing.
It’s frustrating knowing I probably know half a dozen people who could do this in 30 minutes, but they all live on the other side of the world. >.<

There's one thing left to worry about. The left hand focus knobs are, for whatever reason, set in toward the centerline of the focus block about a quarter of an inch compared to the right. The coarse knob almost-- but won't quite-- clear the SZH's uniquely wide microscope body.
If only I had some roughly 80-mil plate with which to fashion some spacers! Oh right...
(/me fishes spacer pieces from previous adapter attempt out of the scrap aluminum pile)
OK! First I need a ring spacer to set the coarse focus knob further away from the centerline.
Done! Now, the fine focus knob needs to be set away as well.
I considered making a shaft spacer, but it will weaken the overall assembly. Instead, I heated the brass inset in the fine focus knob until the ABS softened, then pushed it in 80 mil. I did use a guide to make sure it pushed in straight and flat-- no wobbling allowed.
The fine focus also has a spring-loaded friction mechanism to add a little resistance to it drifting. One side is built into the knob, which I just moved out 80-mil. So I need an 80-mil spacer to take up the slack.
Don't worry, the hammer in the background is a specially designed precision optics hammer.
The Order of Truth's Aeon Priests have resurrected our May 2014 Numenera Bundle, featuring the tabletop science-fantasy roleplaying game Numenera from Monte Cook Games. A billion years in the future, explore the Ninth World to find leftover artifacts of nanotechnology, the datasphere, bio-engineered creatures, and myriad strange devices that defy understanding. The inspiration for the recent Torment: Tides of Numenera computer game from inXile Entertainment, Numenera is about discovering the wonders of eight previous worlds to improve the present and build a future.
No art right now, just meanings. The 78-card jeng-zai deck corresponds to the traditional Tarot but is specifically a hexarchate Tarot circa Kel Cheris' era. As such, upright sixes are all positive while upright sevens are negative, and the fours are lucky/unlucky.No spoilers if you haven't read anything in the series (Ninefox Gambit, Raven Stratagem or any of the short stories), although you might be mildly confused and not get some of the jokes.
This site is for entertainment purposes only: neither guarantees nor apologies are given for the accuracy or inaccuracy of any reading you may receive, and no responsibility is taken for any calendrical rot that may ensue. Hopefully you do not live in the hexarchate.
I've set myself three requirements for the focus block graft:
- No modifications whatsoever to the original SZH microscope body
- End result has to work exactly as intended. No half-functional hacks.
- The end result must look professional, bordering on factory quality.
My original plan: Remove the microscope body mount from the block's dovetail, cut the ring part off, machine the remaining bit flat and add some additional bolt holes to secure it to the SZH.
And that kinda sorta works!
Unfortunately, the remaining block is not quite deep enough for the adjustment knobs to clear, nor is it tall enough to reach all four mounting holes on the back of the SZH body. That means I need to machine a spacer that would have to bolt to the mounting block, then those two pieces could mount to the dovetail and the scope.
Then I thought 'what am I doing?', chucked it, and grabbed a piece of aluminum that's actually the right size to start with.
So let's do this part again.
Sadly, no Chinese manufacturer to date has cloned an SZH, but there are clones of other Olympus focus blocks.
None of these will fit as-is of course, the SZH is weird. But several look to be moddable with a little effort. So I chose a clone of a nicer Olympus coarse/fine assembly.
And now, a review of the FYSCOPE STEREO ZOOM MICROSCOPE COARSE AND FINE FOCUS ARM A4 76mm Size! ( Read more... )
(also open to suggestions for rehoming them, because what I am doing isn't working)
I actually like my AmScope. It's not exactly precision-manufacture and god only knows what glass it uses, but it's durably made, fairly ergonomic, and works well for the price. Only one regret: The camera port is damned near useless.
For some reason, Chinese stereo scopes mostly appear to be clones of old, low- and mid-range Olympus designs. That planted the Olympus bee in my bonnet.
You've probably heard that Nikon is a world-class optics manufacturer that just happens to make cameras. Well, Olympus is a world-class optics manufacturer that just happens to make microscopes.
Looking for no-holds-barred top shelf stereo optics, the current top of the Olympus stereo line is the SZX12. Which is awesome and even broken surplus parts are so far out of budget it's not funny. Mostly the same for the SZX10, its slightly less featureful little brother.
But it turns out the very top of the discontinued predecessor line, the SZH10, is similar enough that it takes many of the same accessories and was every bit as good a scope. And the SZH10 was just a minor feature tweak of the earlier SZH.
And the SZH line is so gloriously 1980s. I mean, just look at this ad. It's not a stereo zoom. No, it's a *super* stereo zoom. And raytracing is involved somehow. And lightning. This here 'scope is obviously real wrath-of-god stuff.
Anyway, the rest is serendipity: There just happened to be enough cheap-ish parts on eBay to hopefully piece together a complete SZH with no major flaws.
Parts have arrived, so here we go...
On the downside, one of my suitcase's tiny TSA-approved locks had gone missing. My brother had advised me to take along an extra one or two-- I should have listened! Ah well. I used a bit of wire to secure the now-unlocked compartment.
( Cut for images! )
I saw a thing yesterday that said “Buying fabric and sewing fabric are TWO SEPARATE HOBBIES.”
I actually feel that I understand so much more about the world now.
I’m now up to 6 artist’s figurines (I need to write more reviews) and I was unable (or unwilling) to resist a set of 14 archival color pens, plus all the stuff I already own, but do I actually draw? No, hardly ever. (That said, I’ve done more this year than in many years.)
Anyway, point is I’m back to that “I want to draw some silly little story like Questionable Content only about, IDK, fat 40somethings instead of hipster robots” thing. Except I really don’t want to draw a story about fat 40somethings because ugh life. I want to do something cute and funny that I don’t have the skill set for but who cares I’ll do it anyway because it doesn’t matter. Or something. And I want just enough pressure to help me do maybe half an hour of art a day without having any real expectations.
Which of course is not much like my personality at all, because yes, I have met me. :p

Having cried all over the WRINKLE IN TIME trailer, I thought I’d better re-read the book immediately to get a proper feeling for it again. It’d been at least twenty, possibly thirty, years since I’d read it, and…
…it’s kind of equally weirder and more mundane than I remember it.
I was prepared for, although somewhat exasperated by regardless, the Christian allusions; whenever I last re-read L’Engle, I was adult enough to notice her books are really laced with Christianity, so I knew that was going to be there. The story itself is actually a lot more straight-forward than I remember it being; possibly I’ve conflated the other books with it, or maybe it’s just that the weird bits are SO STRANGE that I thought the story structure had to be a lot more complicated than it really is.
It’s not, from a modern storytelling perspective, especially well told. It takes about four chapters to really get going, and it’s only a 12 chapter book. There’s a lot of telling, but not much in the way of showing in terms of…*why*. Meg is not, to the adult modern reader, particularly sympathetic: she doesn’t fit in at school, she’s angry in general and specifically very defensive about her father’s absence, and is apparently some particular kind of dumb that excludes being spectacularly good at math. That dumbness may be meant to indicate she’s socially inept, but although that certainly appears to be true, it doesn’t seem to be what’s really going on.
But that…dumbness…whatever it is…is crucial through the whole book. Meg doesn’t tesseract as well as the others. Meg is more vulnerable to the Darkness than the others. Meg won’t understand if you explain the thing…but I never understood why. (I’m not sure I understood as a kid, either, but it didn’t matter as much to me then.) And it’s apparently not something that came on simply because Mr Murry disappeared, because even he comments on it, and had done so before his disappearance, so you can’t lay her anger/ineptitude at the feet of her father’s disappearance.
And, just as much as Meg’s lack is not explained, neither are Calvin and Charles Wallace’s aptitude. Calvin communicates well; well, okay, that’s fine, but why does it make it easier for him to tesseract? Charles Wallace is, as far as I can tell, not even actually human, and Calvin, who does not come from the Murry family at all, is apparently More Like Charles than Meg is. But I don’t know what they are, or why they are, or why they’re the special ones and our heroine isn’t (well, that last one is institutionalized sexism, but let’s move past that). I remember *loving* Charles Wallace (and crushing terribly on Calvin), but I find him fairly creepy now, and that’s as the parent of an extremely self-assured little kid who, like Charles Wallace, is quite certain he’s able to Do It His Way without listening to the wisdom, or at least the experience, of his elders.
The one thing that maybe felt the most true to me in the whole book was Meg coming around to being the one who can save Charles Wallace. She wanted someone else–her father, specifically, but ANYBODY ELSE–to have to do the hard work. She was terrified and resentful of having to do it herself (and possibly that’s what the aforementioned “dumbness” is, since everybody keeps saying If you’d only apply yourself, Meg,, but that still doesn’t explain why she doesn’t tesseract as well, etc), and that seems very appropriate to a 13 year old to me. To people a lot older than 13, too, for that matter. But it comes in the 11th
hourchapter, and her willingness to go on there is the only time in the book that she moves forward of her own volition. I’m not saying that isn’t fairly realistic, maybe, for a young teen, but in terms of making a dynamic book, it…doesn’t, really.
There are parts of the book that remain wonderful. The Mrs W are still splendid; Camazotz (which I always read, name-wise, as being what happens when Camelot goes terribly wrong) is still EXTREMELY CREEPY, and the thrumming presence of IT remains startlingly effective. Aunt Beast is wonderful. (So basically: the aliens work a lot better for me than the humans do.)
It doesn’t feel like a book that could get published now. It would need more depth; it felt shallow to me. A lot of its weirdness seems to me like it came very specifically out of the 50s and early 60s; I don’t think that book would, or perhaps *could*, be written now. It’s very internal in a lot of ways, and I’m really looking forward to seeing how the film adapts the weirdness and the internalness and Meg’s basic lack of agency into an accessible story. My *feeling* is that they’re going to do a magnificent job of it, that it’s going to be one of those cases like Frankenstein or Jeckell & Hyde where the book’s conceptual foundation proves more powerful in film than it does on the page. I hope so!
But you know what I really wanted to do when I finished reading A WRINKLE IN TIME? I wanted to re-read Diane Duane’s SO YOU WANT TO BE A WIZARD, because I felt like the Young Wizards books use A WRINKLE IN TIME as a conceptual springboard and dove off into something that worked a lot better as a *story*.
So I guess I know what’s up next (or soon, anyway) on the Catie’s Re-Reads list. :)

Having downloaded a bunch of public domain books, I then went looking for the proper cover art. Interestingly, although I am convinced I owned mid-1970s editions of both Blackman's Burden and Border, Breed nor Birth, I can find no evidence those editions actually existed.
Another interesting thing. This is the list of science fiction books on PG and this is the list of science fiction works by women on PG.

Why paint so much that's just going to be covered by the title and top image of a face? (a) portfolio work and (b) to potentially sell as prints. :)
(also: the window started from a 3D program and the wall started from a copyright-free set of textures, and then I painted over them and photomontaged stuff into them. I can't draw lines that straight.)
One important thing to note here is that the TPM doesn't actually have any ability to directly interfere with the boot process. If you try to boot modified code on a system, the TPM will contain different measurements but boot will still succeed. What the TPM can do is refuse to hand over secrets unless the measurements are correct. This allows for configurations where your disk encryption key can be stored in the TPM and then handed over automatically if the measurements are unaltered. If anybody interferes with your boot process then the measurements will be different, the TPM will refuse to hand over the key, your disk will remain encrypted and whoever's trying to compromise your machine will be sad.
The problem here is that a lot of things can affect the measurements. Upgrading your bootloader or kernel will do so. At that point if you reboot your disk fails to unlock and you become unhappy. To get around this your update system needs to notice that a new component is about to be installed, generate the new expected hashes and re-seal the secret to the TPM using the new hashes. If there are several different points in the update where this can happen, this can quite easily go wrong. And if it goes wrong, you're back to being unhappy.
Is there a way to improve this? Surprisingly, the answer is "yes" and the people to thank are Microsoft. Appendix A of a basically entirely unrelated spec defines a mechanism for storing the UEFI Secure Boot policy and used keys in PCR 7 of the TPM. The idea here is that you trust your OS vendor (since otherwise they could just backdoor your system anyway), so anything signed by your OS vendor is acceptable. If someone tries to boot something signed by a different vendor then PCR 7 will be different. If someone disables secure boot, PCR 7 will be different. If you upgrade your bootloader or kernel, PCR 7 will be the same. This simplifies things significantly.
I've put together a (not well-tested) patchset for Shim that adds support for including Shim's measurements in PCR 7. In conjunction with appropriate firmware, it should then be straightforward to seal secrets to PCR 7 and not worry about things breaking over system updates. This makes tying things like disk encryption keys to the TPM much more reasonable.
However, there's still one pretty major problem, which is that the initramfs (ie, the component responsible for setting up the disk encryption in the first place) isn't signed and isn't included in PCR 7. An attacker can simply modify it to stash any TPM-backed secrets or mount the encrypted filesystem and then drop to a root prompt. This, uh, reduces the utility of the entire exercise.
The simplest solution to this that I've come up with depends on how Linux implements initramfs files. In its simplest form, an initramfs is just a cpio archive. In its slightly more complicated form, it's a compressed cpio archive. And in its peak form of evolution, it's a series of compressed cpio archives concatenated together. As the kernel reads each one in turn, it extracts it over the previous ones. That means that any files in the final archive will overwrite files of the same name in previous archives.
My proposal is to generate a small initramfs whose sole job is to get secrets from the TPM and stash them in the kernel keyring, and then measure an additional value into PCR 7 in order to ensure that the secrets can't be obtained again. Later disk encryption setup will then be able to set up dm-crypt using the secret already stored within the kernel. This small initramfs will be built into the signed kernel image, and the bootloader will be responsible for appending it to the end of any user-provided initramfs. This means that the TPM will only grant access to the secrets while trustworthy code is running - once the secret is in the kernel it will only be available for in-kernel use, and once PCR 7 has been modified the TPM won't give it to anyone else. A similar approach for some kernel command-line arguments (the kernel, module-init-tools and systemd all interpret the kernel command line left-to-right, with later arguments overriding earlier ones) would make it possible to ensure that certain kernel configuration options (such as the iommu) weren't overridable by an attacker.
There's obviously a few things that have to be done here (standardise how to embed such an initramfs in the kernel image, ensure that luks knows how to use the kernel keyring, teach all relevant bootloaders how to handle these images), but overall this should make it practical to use PCR 7 as a mechanism for supporting TPM-backed disk encryption secrets on Linux without introducing a hug support burden in the process.
 The patchset I've posted to add measured boot support to Grub use PCRs 8 and 9 to measure various components during the boot process, but other bootloaders may have different policies.
 This is because most Linux systems generate the initramfs locally rather than shipping it pre-built. It may also get rebuilt on various userspace updates, even if the kernel hasn't changed. Including it in PCR 7 would entirely break the fragility guarantees and defeat the point of all of this.
Torchship Captain Book Cover by sfolse on DeviantArt
Torchship Captain, the cover of the third book in Karl K. Gallagher's (aka selenite0) science fiction trilogy. I'll get the version of the cover without the title and the face on top posted before too long.
If anybody happens to wander by and sees this, and is in the market for a book cover painting or a cover made from stock photos I can do that!
