Over on YouTube Curious Droid has uploaded an interesting video that attempts to explain the purpose of the HAARP transmitter project. HAARP has also been a popular target of conspiracy theorists who believe that the transmitter must have some sort of sinister purpose. Curious Droid’s video explains the purpose and science behind HAARP elegantly, hopefully dispelling any conspiracy theories.

Predictability · The Go runtime is garbage-collected, but the GC design is consciously optimized to be predictable and not induce latency; here’s a nice deep-dive. And unlike other concurrency frameworks I’ve fought with, you can pretty well just fling a (potentially huge) number of tasks at goroutines, and empirically, the runtime does a good job of keeping the cores busy and the work flowing through. And (assuming a little care with buffer sizes) it’s very unlikely that you’ll get a deadlock or an annoying race-condition bug.

Libra is built on a secure, scalable, and reliable blockchain and is designed to help bring people everywhere equal access to financial services. Libra is built on a secure, scalable, and reliable blockchain and is designed to help bring people everywhere equal access to financial services. Libra is backed by a reserve of assets so that its value stays stable.

In addition to releasing details about the Libra Coin via a white paper and other explainers, Facebook also revealed a software “wallet,” called Calibra, which would be maintained by a non-profit, would store user funds and could provide financial services. On the first point, Marcus said that Facebook is enforcing a strict separation between users’ social data—their Facebook likes, photos, etc—and the financial data that will be available on Libra’s network. Indeed, that’s why Calibra, the wallet software that will hold Libra Coins, was made a subsidiary of Facebook—“to ensure appropriate separation between social and financial data and to build and operate services on its behalf on top of the Libra network,” as the white paper explains.

This repository contains the spilld SMTP and IMAP server, built around a new SQLite-based storage format, spillbox. It may change in incompatible ways and no tool will be published to automatically migrate spillbox data until the project uses version numbers. The development version can be installed with go get:

If this is an offline account, the system stores the user name, NTLM, SHA1 password hashes along with some other private information to the LSA secret named this is a Microsoft account, then (Windows 1607 and earlier) 1703 and later) secret is created. After the PC is rebooted, the system identifies the TBAL token and decrypts the DPAPI primary key using either a SHA1 hash of the user (for an offline account) or a 96-byte key if it is a Microsoft account. The problem for a user is that after the system is shut down, anyone who has physical access to the PC can use the stored TBAL secret to decrypt the DPAPI primary key and, as a consequence, all the user’s data that is encrypted using DPAPI.

Duties include creating documentation to modify aircraft, on-aircraft troubleshooting, flight test support in the Mission Control Room, installing Operational Flight Program (OFP) updates, post-flight mission anomaly resolution, and generating detailed troubleshooting plans and reports. This position is located at a facility that requires special access. • Requires experience with state-of-the-art aircraft system technologies such as integrated modular system architectures, fiber optics, high capacity memory devices, fault isolation technologies, high-speed data busses and MIL-STD-1553B communications busses.

A paper published today in the Proceedings of the National Academy of Sciences found that dogs’ faces are structured for complex expression in a way that wolves’ aren’t, thanks to a special pair of muscles framing their eyes. For the study, a team at the University of Portsmouth’s Dog Cognition Centre looked at two muscles that work together to widen and open a dog’s eyes, causing them to appear bigger, droopier, and objectively cuter. The retractor anguli oculi lateralis muscle and the levator anguli oculi medialis muscle (mercifully known as RAOL and LAOM) form two short, straight lines, which connect the ring of muscle around a dog’s eye to either end of the brow above.

Earlier in this post, we talked about Merkle trees as useful for commitment schemes and data integrity guarantees, but Miller et al. instead chooses to frame them as useful for delegation of data. If I have a Merkle tree with millions of elements in it, I can hand it over to a third party, retaining only the top hash, then make queries to this data expecting both a value and an inclusion proof. In Revocation Transparency, they introduce the notion of a sparse Merkle tree, a Merkle tree of infeasible size (in their example, depth 256, so a node per thousand atoms in the universe) where we exploit the fact that almost all leaves in this tree have the same value to compute proofs and digests in efficient time.

Just think: Someone in this world is an authority on the topic of whether mice can or cannot put on two-tone shoes, derby hats, pinstriped shirts, and Dacron pants, and pass as humans. The story was about a real dog, and I used to watch him and try to get inside his head and imagine how he saw the world. It was always my hope, in writing novels and stories which asked the question “What is reality?”
