made out of meat. making computers pretend to be computers

a rust impl. it's four lines. there is a type that is bounded by a two-lifetime existential. it's atrocious.
a screenshot of some source code. "dumpbin knows about fstpnce as fstp1, but masm does not. since this is an undocumented instruction anyway, decode it ourselves..", followed by a match arm translating from some instruction bytes to an "fstpnce st(3), st(0)".
a diff of section of a markdown document with the header "future" up top. the sentence "and 32-bit/16-bit x86." has been struck out, and the text reflowed.
a narrow slice of sky, all grey from a thin smear of cloud across the frame. the sun is a bright splotch to the left, and darker clouds line the bottom of the frame varying from a bluish(!?) to outright dark grey. there are some rays of shadow cast from the clouds out away from the sun. in the middle of the frame is a bird going out towards the distance.
NASA808, a gulfstream 3, ADSB doing really whacky looping tracks around where integrity came in
integrity and the three main parachutes. the image is greyscale, infrared. integrity is glowing and clipping in brightness.
a less noisy and much wider angle spot of sky. a bright star is clearly drowning out the image, reflecting off of parts of the imaging train and casting shadows on the sensor. it's a very weird image. somewhere in the center is a very faint grey non-smeared speck.
another greyscale image, with stars as almost-horizontal smears. in the center of the image is a very faint grey fuzzball, that's Integrity.
another greyscale image, there's a dot in the middle and stars are smears going towards the bottom right
greyscale image with some light diagonal smears across the frame and a horizontal smear with an orange ellipse around it in the middle. the horizontal smear is the Orion spacecraft
Beat from UNBEATABLE standing at a buffet looking mildly disinterested. there is a speech bubble above her head with the text, in parentheses: "I am an adult and I understand that my actions have consequences." the careful viewer will notice that the E to switch to the next dialogue option is greyed out, implying (correctly) that this is the last option.
cat paw on a couch, claws fully out
a hex dump from the illumos modular debugger, having printed the value of the variable "gdt0", then dumped 0x90 bytes of stuff from the address that printed
a QSPI description from nordic semiconductor's website, it is a "27 minute read" with a "Summarize" button that i've clicked. the summarize button produced a "Zoomin GPT summary" box which so far has simply reproduced the exact text of the article
the post you're replying to was marked as being written in Japanese by its author. Would you like to reply in *Japanese*?
i'm in the slop list! evidence is that i learned something from Claude once.
palmer luckey doing pearl clutching about people calling for people to be murdered, in reply to a palantir cofounder saying "communists" and "islamists" should be murdered
c/2025 A6 (Lemmon), the comet that recently passed by. the comet itself is a bright spot at the lower right, with a greenish glow about it. there's a prominent tail through to the upper left of the image, a diffuse reddish-grey smear with slightly brighter blueish veins. stars are visible across the frame as splotches of red, green, and blue from the individual channels that were composed for this image.
a chain of three skeets: quantian: At this rate the 2026 Dem meta will be running dead-eyed CIA officers whose campaign ads are just them graphically describing what war crimes they will do to Republicans Ed: i presume there are also negatives Faine: yes I would also like to hear about the negatives
a greyscale picture of a very bright smudge with a dusty smear behind it. several stars are in the frame lightly smeared up-and-to-the-right, clear evidence the camera is tracking the comet rather than the sky behind it
a screenshot of a discord conversation wherein i ping Eliza to tell her that i realized a serial thingy i did has a miserable pain in the ass bug. "the parts that aren't the bug are not reprehensible now, but it also is unlandable as-is" an hour and a half later Eliza responded with an eyes emoji, presumably looked, and then below the "new" message divider is simply "oh no ixi oh fuck"
a screenshot of the dow jones industrial average. it has been going up and to the right and beyond the dot com peak since about 2010
a screenshot of a cpuid dump from github, for Granite Ridge. a value for register eax from CPUID leaf 8000001A is highlighted and has the value "0000000A"
the image above but in that "the A/C is on, he has water and is listening to his favorite music" meme
a pile of wires, LEDs, and a very blurry 7-segment display in the background. there's a switch on the left-hand side under some single-board computers, and on the right is a dangling SSD leaning against a tiny motherboard with a rather large heat sink and fans on it. the SSD is for some reason in a hot-swap bay.
a gdb invocation single-stepping through a program. it queries cpuid, shows that leaf 1 ecx reports that pclmulqdq is not supported, then boldly executes it anyway. it runs fine. exact text does not transcribe well probably: > gdb --batch-silent --command dbgscript -q --args taskset -ac 4 ./pclmulqdq Function "_start" not defined. 0x401010 <_start>: mov $0x1,%eax 0x401015 <_start+5>: mov $0x0,%ecx # cpuid leaf: 0x1 0x40101a <_start+10>: cpuid # leaf 1 ecx: 0x7ed83209 # - bit 2 (pclmulqdq): 0 0x40101c <_start+12>: movups 0x401000,%xmm3 0x401024 <_start+20>: movups 0x401000,%xmm4 0x40102c <_start+28>: pclmulhqhqdq %xmm4,%xmm3 0x401032 <_start+34>: mov $0x3c,%eax 0x401037 <_start+39>: pextrq $0x1,%xmm3,%rdi => 0x40103e <_start+46>: syscall [Inferior 1 (process 279224) exited with code 04] # exit code: 4
disassembly of an instruction in gdb. it is "pclmulhqhqdq %xmm4, %xmm3". sorry if something tried to read that as a word.
a screenshot of the last six replies before this post. there's also a search bar for the word "reddit". it has five hits, all in frame. the person i am replying to made the first mention of reddit in this entire conversation tree.
the Intel Software Developers Manual open in a PDF viewer, with a search open for "page table" showing one of 155 hits. the hit it is showing is a match for the top of a page that says "page" at the right side as one header, and "tables" at the left side, a line below, as a header for a different column.
john's picture from the top, but the alt text says the rainbow is trailing off the right. it is the left. john has confused left and right.
a disassembly of some hexagon code. at most offsets there are instruction bundles with multiple instructions, often ending in a predicated jump or other predicated operation. there are a few single-instruction bundles in here but not many. there are "TODO: error; unconsumed extender" littered in between the lines.
a screenshot of a table from report.nih.gov outlining research/disease areas and dollars (in millions) spent over years 2016-2024/2025 estimate. the table is scrolled to the bottom, the last four rows are Women's Health, Wound Healing and Care, Youth Violence, and Youth Violence Prevention.
an image i got from the second result googling "Twin Quasar". a more exposed and mildly more colorful view of the field that Emily pictured above. it's also rotated almost 180 degrees from Emily's pictures. there is a circle around the twin quasar, and a few bright stars around it that all line up very obviously with the stars in Emily's closer crop of the region around the twin quasar.
emperor palpatine meme but the text is "i love regular expression"
a cat stretched out sleeping on a blanket, which itself is on couch or sofa or something. the photo is washed out and blurry, and a box in the back is reflecting the sun so it's pretty washed out too. it's a bad picture but the cat is very comfy
language selector for a website, on the left is a button saying "Switch to US site". on the right is a link that says, typo and all, "continue to intenrational site". between them is a bare "or"
"Despite the name, a non-directive is a preprocessing directive." section 6.10.3 of the document this screenshot is from
disassembly of a few x86 instructions. registers are a dark cyan, a few `xor` are present in a dark blue, `jmp` is green, `ret` is red.
the solar eclipse from april 8 2024. the sun is fully occluded by the moon, but the corona is still almost blindingly bright around the moon. wisps of plasma from the sun's corona radiate out in irregular lines around the sun. a few stars are visible around the sun as specks; two close to it on the left, and two further to the right of the field of view. the moon itself is very dimly illuminated from earthshine, just enough to see large surface features but dim enough it could be missed at a passing glance.
7. Doc Brown (Back to the future): 85%
a perf report of something called "capstone differential", with some functions at the top like AArch64_getInstruction and cs_disasm_iter. AArch64_getInstruction is 40.19% of runtime, while yaxpeax-arm's decode_into is 0.39% of runtime about 20 functions down. between the two are many functions related to writing strings, malloc, realloc, string searching, text parsing, nothing obviously related to instruction disassembly.
mass text encouraging me to vote Margarita Wilkinson (a californian politician, lol). her campaign points are "restoring law-and-order, combating crime, and keeping our communities safe". i asked if she is for restoring law and order, does she support there being consequences for a sitting president inciting an insurrection against congress? the next message is: "You have successfully unsubscribed."
some kind of guy who is probably mad that water is wet
the root page of ci.butactuallyin.space. it lists a dozen and a half repos, most of which are rows including their last build date, a job number, build commit, build duration, status, and job result. there's a second table of active/in-progress tasks, where two are building the same commit and have been ongoing for 12 seconds or so.
same image as before but now link looks normal, and not a garbled mess
a screenshot of a frame early in Legend of Zelda: Oracle of Ages. nayru is sitting on a tree stump on the left, singing a nice song. link is on the right and his lower half is... fine... but his upper half is super glitched out
in some regards, a picture of the annular solar eclipse on saturday. the sun and moon are at the lower center of the image. together they cast a dozen odd fringes of light, no doubt reflections through the lens's optical elements. additionally, the whole frame is mildly overcast - towards the center the clouds break a bit and have more scattered and sharp structure to them. as the clouds extend out to the edges of the frame, they blur together into a greyish mass at the upper corners, and fade into black at the bottom. at the top of the picture, a Bonanza happens to be making the trek to Colorado at this very same time. it's pointed to the bottom left, and it's a totally black silhouette of a plane against the cloudy background of the sky.
some kind of personality test thing saying that i am a grass type pokemon, who is always tired, thoughtful and sweet, lives like a senior adult, and am into mori style outfits. i was assigned the catch phrases "uh, what's that ?", "let me help !", "i can do it !", and "can anyone take care of me, please ?" at birth
a screenshot of the gamecube's wikipedia page, specifically its dimensions (150x161x110mm)
me posting in discord: "let me show you what certbot does when i run it" "uh......" "i broke it =D" "well shit" (this got a skull react) "cert's fixed" (got a tada and checkmark)
also saturn (greyscale), with a weird kinda halo around it for some reason??
screenshot of the reply to me, not only is it the text "All the time", but bluesky is offering to Translate This Post
bluespacecanary and permadeath.com posting at each other, but then replicated four times from a bsky UI bug???
the start screen of link's awakening DX. it looks correct! there's color! hurray!
okay <3 yay <3 meme post but the first text is "what's an sre everyone keeps talking about it"
a chart showing throughput (megabytes/sec) comparisons of a few x86 disassemblers and three versions of yaxpeax-x86. yaxpeax-x86 1.2.0 is about 20% faster than 1.1.5, which itself is tied with iced-x86, with the rest of the pack far behind
a picture of an 80960CA user's manual. the cover is three 80960CA ICs that seem to be looming over you, encircling you.
the center(ish) of a galaxy, in black and white. the center of the galaxy is a bright spot above the middle of the image. rest of it is swirling around the center, with dust clouds carving out regions and structures through the mass of stars. it's dusted with a haze of noise particularly in the darker regions, not so much as to distract but enough to know that more faint details linger in wait of a longer exposure
four skeets from retr0id in a row, three of which are blank (not even an empty line of text), the fourth appears to be a quote of itself
