I hate to break it to you guys but there's nothing cool hiding in the labs.

Everything that is even remotely advertisable has been advertised by these companies to try to increase stock value.

The culture that built the SR71, the B2, battleships, Space Shuttle etc simply doesn't exist anymore.

It's a lot easier to tell ourselves "we didn't ACTUALLY go to the moon" than it is to admit that we effectively live in the ruins of a more advanced civilization that briefly appeared in the 20th century, but was bashed into the grave by bureaucracy, social spending, and contract mismanagement.

Look at NASA:
- Webb a decade behind schedule
- Grace Roman a decade behind schedule
- X59 half a decade late
- DreamChaser dead on arrival
- X33 dead in the cradle
- X38 dead in the cradle
- Starship/Falcon 9 developed independently of NASA objectives
- ISS on life support with no proper follow-on.

Yes, Isaacman is fighting to change this, but this is clearly the track record of an agency that did not continue the pace of the 20th century.

I have the honor and privilege of getting to experience a LOT of America's engineered solutions for space, and I continuously find myself more impressed with the 40 year old hardware being replaced than what we're replacing it with.

Simply put: we don't have *it* anymore.

We need to get it back. We need more Boom Supersonics, a new Skunkworks, an army of Elons. We need the government to be run by Isaacmans with a civic leadership all in agreement that their job is to BUILD the Republic, not to "manage" it.

So, how do we get there? How do we bring this back?

Middle-aged suburban moms are stealth, early tech adopters.

They just care more about cutting cloth than conspicuous computation.

E.g., this lady's sewing room has a spatially registered AR system projecting vector patterns onto fabric, plus a CNC sewing machine.

As someone living in Kyiv, I’m begging you:

Please help us stop this.

Almost every night, russia strikes Kyiv with ballistic missiles, hitting civilians, homes, and warehouses.

We can’t stop these missiles because we don’t have enough Patriot systems.

People are dying.

Please don’t look away. Share what’s happening in Ukraine. Help us save lives.

Si @Claudiashein tuviera alta aprobación no trataría de censurar a los pocos medios y opositores que decimos la verdad.

Su presidencia es ilegítima porque llegó financiada por un narcopartido y así pasará a la historia.

The United States is hunting down, dismantling, and destroying Cártel de Jalisco Nueva Generación. @StateDept is offering rewards totaling over $100 million for information leading to the arrests and/or convictions of their leaders and associates. We are also imposing visa restrictions on 65 individuals and revoking 26 visas of family members and associates of persons linked to the cartel.

HOLY SHIT WHAT

Mamdani's "socialist" grocery stores are going to be run by private operators? And they receive the right to run the store from the government but then control the supply of discount cards themselves? And they have full discretion over purchasing and hiring decisions in a situation where they are guaranteed to make a profit irrespective of how inefficient the operation is because they're undercutting their competitors' prices by 30% via government subsidies?

Buckle in, you suck fucks! Real corruption has never been tried!

In 2015 I formed a small group of engineers at Jane Street to rebuild the firm’s core trading system from the ground up, and we ended up cutting latency by two orders of magnitude. Some of the techniques we used, relevant for algorithmic trading systems and exchanges today:

Zero allocation: Whenever a program allocates memory for an object on the heap, the runtime pays a steep penalty in latency. The simplest solution is to avoid memory allocation entirely.

Jane Street famously uses OCaml, a strongly typed programming language that by default produces garbage collected by a dynamic collector. Most other firms use languages with manual memory management, but it was a strict part of Jane Street’s tech culture that all risk-sensitive code had to be written in OCaml. It took a collaborative effort across multiple groups within Jane Street’s technology org to create zero-allocation core libraries, combining the type safety of a functional programming language with the memory profile of a language like C.

We built the new main trading loop in this hybrid OCaml/C-style, producing zero new allocations in the critical path from tick to trade. In modern languages like Rust, it is substantially easier to achieve precise memory management while still benefiting from type safety and compile-time guarantees.

Kernel bypass: A primary goal of a low-latency trading system or exchange is to pull a network packet containing market data or order flow through the network card’s interface and into the program’s memory space as fast as possible. The standard Linux OS kernel uses slow abstractions to support a wide variety of network drivers, at the expense of the entire system’s end-to-end latency. When we started with an empty program that contained no business logic and only forwarded packets through when received, the end-to-end latency was already too slow.

To fix this issue, we employed a standard practice in the HFT industry in which we bypassed the OS’s kernel stack entirely by leveraging our network card vendors’ proprietary APIs to DMA packets straight from the NIC into memory. This technique brought our empty-packet-forwarding baseline into the latency regime we needed in order to build out the rest of the trading, risk, and protocol code.

Local IPC: Kernel bypass is necessary when reading routed packets off a network from a third party such as another exchange or client connection. When communicating between internal instead of external processes, the fastest transports avoid network stacks entirely.

Processes within the same box can transfer messages using shared memory or Unix domain sockets. This allowed us to continue with our familiar process boundaries for separable components without sacrificing significant performance. We had to write custom logic to emulate many of the features of network- and transport-layer protocols, with the result of creating a reusable, zero-overhead IPC mechanism.

Working on this problem was one of the most intellectually rewarding experiences of my early career. The above latency optimization techniques are fairly commonplace in the HFT trade but hard to learn outside the industry setting. Half of our team at Architect comes from Jane Street and other trading firms, and we value using our domain knowledge to build exchanges for the public rather than trading software that never leaves an HFT’s walls.
