Have you ever wondered about the construction techniques, materials, and components selected for Military applications?

Military Technology is technology. Military Technology is widely understood to filter down into commercial use, however if you look i suspect you may find that there is just as much Civilian Technology filtering its way upwards in echelons of Military Technology. The appropriate terminology for this is Dual Use.

Universities have received funding for nearly a hundred years in the west to produce scientific research that is of interest to western Military apparatus. Many of these innovations can then be patented, and sold on the civilian market, or in the case of basic research, its insights are normally, and for the most part directly available to anyone. For example, the mathematics of anti-aircraft seeking missiles is freely available today, likely at your local public library.

My sense is that the lion's share of innovations in Military Technology lie in the hardening, ruggedization and construction techniques instead of some kind of transcendent alien technology, or some secret trove of found or developed technology hoarded by the Military. Most of the special sauce is nothing special at all. Some of it is quite unique, however.

An engineering problem is encountered and a corporation fulfilling the Military contract is incentivized to fund scientific research, sometimes basic research in order to solve it. In the Civilian sphere, you will rarely encounter a customer who required a bespoke solution at an industrial scale.

The result is an interesting admixture, especially of older specimens, of now-commodified-cheap componentry and hand assembly. There is a tremendous amount to be learned from the study of current and historic developments.

This French🇫🇷 man sources and records tear downs of many types Military Technology, from vintage AIM-9 IR Seeker heads and their Soviet counterpart, the K-13, to Military RF gear, Flight Avionics, and even an examination of a recovered Iranian Shahed One-Way Attack Drone servo and control surface. The results are truly illuminating.

What else could people learn from this rubble?

Hey all. Any of you into IEMs. I'm trying to find myself a nice new pair. My current ones are CCA CRA's they were cheap ChiFi and are alright just a bit tinny. I was looking at the Aria 2's and possible the EA1000s. If any of you have any good recommendations please let me know. Many thanks.

ive always been an IEM guy but i just go for the cheap shit and use a good quality headphone amp

been rocking the KZ ZS10 Pro's for the past few years and have no complaints - usually pair them with my Hidizs AP80 - i really only use my IEM's on the go

always use foam tips too and toss out the current tips when they are dirty, im not particular about brands, just whatever i can find on Amazon around when i need a new pack of replacements

I use this. Got it for $50 a few years ago at the request of a consumerist friend.

It sounds good, better than anything else I ever owned, but I couldn't tell you the technical reasons why.

Hello all!

As of today: 03/04/2026 I have had my Moondrop Aria 2's delivered.

So far they have been quire decent compared to my CCA CRA's, the sound stage is a lot nicer.

They are very decent for electronic music, and a lot of death metal. For some metal songs I have come to an issue where certain sounds i.e. cymbals sound a bit 'splashy' I'm told this is because the drivers are coated in ceramic.

These IEMs also have an issue with Classical Music, and Opera. Two Genres I do enjoy when I hear the right pieces. The dynamics of the vocals are hard to represent and you do not hear the full spectrum of the singers voice.

As for the Orchestra sections, you can hear the sound dynamics and the positions of where the different sections are sat. However, certain sections become muddy and are less prominent than others.

Post too long. Click here to view the full text.

Also blessed with the bald gene but you can get a decent idea of your metabolic rate based off your temperature and heart rate when you first wake up. You check these measurements then because your body isn't being influenced by food or anything yet. A good temperature is around 98F and a good heart rate is supposedly around 75-85. I can't personally speak to the heart rate aspect because I've always had high blood pressure but just keep track of your temps and heartrate in a book alongside how energetic you are during the day. Another good time to check your temp and heartrate is an hour or two after a meal. Low thyroid function can cause your temps to drop after meals. The best practice for measuring your temps is to use an old mercury thermometer under the armpit for a few minutes. This is just all the stuff I've found over the past year or so. I haven't gotten to implement this into my daily routine. I just go off of vibes.

>Most people building off of his work should be taken with a huge grain of salt
Agreed. Same as anything else in that there's grifters and snake oil salesmen. Personally I like Arcane Vitality and Danny Roddy.

Can we change this to a peating thread? I'd love to have a place to check weekly with personal updates, tips, and other crud.

ive been experimenting with the "pro-metabolic" coffee lately (coffee + raw milk + honey + pinch of salt) and my morning temps are finally cracking 97.5 consistently instead of hovering in the 96s like a dead fish. still cant hit the mythical 98 tho

also i noticed i used to be able to grind through 8 hours of coding on nothing but black coffee, now if i skip a meal i turn into an actual retard and cant focus for longer than a few hrs at a time before the brain drain hits. wondering if anyone else has experienced similar? is this a result of too much sugar or not enough?

(also shoutout to the tranny anon in >>14 for actually posting real experience instead of copypasta, rare sight these days)

Ayo, so peep this—binary hypercubes is like CUBES, but on some next-level ish…
You know how a regular cube got corners and edges, right? What if you start stackin' more dimensions on that? So you ain't just stuck in the third dimension—now you got 4, 5, maybe even 10 dimensions, all twisted up.

Each corner of this cube is a "bit." It finna be like a 0 or a 1–just like yo phone. And all them edges connect the bits–just like how wires hook up yo computer. In a 4D hypercube, you got 16 corners, 32 edges—mad complex.

MAKEUP OF A 4D HYPERCUBE (TESSERACT):
Vertices: \(2^{4}=16\).
Edges: \(4\cdot 2^{4-1}=4\cdot 8=32\).
Faces (Squares): \({4 \choose 2}\cdot 2^{4-2}=6\cdot 4=24\).
Cells (Cubes): \({4 \choose 3}\cdot 2^{4-3}=4\cdot 2=8\).
Total Sub-Hypercubes: \(3^{4}=81\)

Imagine you add another layer of dimensions on top of each other. Now your mind can’t even process it. The more dimensions you add, the crazier it gets, fam.

Bottom line? It’s like a cube that keeps gettin' mad complicated, built outta binary numbers. Ain’t no way to really picture it, nigga. Just know it’s like the next step in computer math and how everything’s connected on a higher level.
