It was much too Early

I'm really unhappy with how the roll-out went. It was much too early. I had been
discussing the project and sharing access to the development environment for
testing and feedback in the SourceHut off-topic IRC channel, which is a
relatively small community, with an explicit request not to share details of the
project more widely outside of the channel. Someone in this channel
misunderstood my request and posted it to Hacker News, and by the time I woke up
and saw it the next morning, it was too late to stop. The search engine is not presently capable of producing useful results for a
large variety of queries. The search index, now being rebuilt for production, is
only a quarter of the size of my local development index. I also have not been
able to verify my assumptions at scale, and I have no clue if we're a few
million pages away from 5-10 second search queries and having to rewrite the
indexing backend, or if our weighting heuristics are wrong and we're going to
have to rebuild the index after some tweaks.

One of lock-based programming's biggest problems is that "locks don't compose": it is hard to combine small, correct lock-based modules into equally correct larger programs without modifying the modules or at least knowing about their internals. Account that allows multiple concurrent clients to deposit or withdraw money to an account; and give an algorithm to transfer money from one account to another. The second part of the problem is much more complicated. In a concurrent program, this algorithm is incorrect because when one thread is halfway through transfer, another might observe a state where amount has been withdrawn from the first account, but not yet deposited into the other account: money has gone missing from the system. This solution gets more complicated when more locks are involved, and the transfer function needs to know about all of the locks, so they cannot be hidden. The ISO/IEC C standard provides a standard mutual exclusion (locks) API since C11.

Playback speed - There are new options to speed up or slow down playback of recordings. Skip silence - Voice Memos automatically analyzes recordings and automatically skips over gaps in your audio with a single tap. Improved sharing - It is possible to share multiple Voice Memos recordings at once. Improved Panorama captures - Panorama mode in iPhone 12 and iPhone 12 Pro now has improved geometric distortion and can better capture moving subjects while also reducing image noise and banding. Zoom in QuickTake video - Users can swipe up or down while taking a QuickTake video to zoom in or out. Improved discovery - Podcasts creates personalized groups of suggested shows about specific topics. Shared with You - Share your favorite podcast episodes in the Messages app and find all the episodes shared with you in Listen Now. Spatial audio with dynamic head tracking - Listeners can now use AirPods Pro and AirPods Max to listen to music with Dolby Atmos and Apple's dynamic head tracking for a more immersive experience.

Internally it can fit up to two M.2 PCIe SSDs. The Asus PB60 strikes a middle ground between a desktop PC and a Mini PC with some internal components from laptops like SODIMM memory and 2.5-inch HDD bays but with the CPU and GPU power of a desktop. We reviewed a previous model two years ago when it featured an Intel i7 as the highest configuration, luckily it has been updated to this year's standards. Inside you will find an eight-core Intel i9-9900T 16GB of RAM and a 1TB hard drive with an NVidia Quadro P620, an apt configuration to run Adobe Premiere or your video editor of choice. You can also find a beefed up version with 64GB RAM and storage upgraded to a 1TB SSD plus a 2TB hard drive at reatail. Amazingly, this configuration upgrade will only set you back an extra $500. It's stackable design resembles two small pizza boxes stack on top of each other. This data h​as been　 do​ne with the  he lp  of GS A Co nt ent Gene ra tor DE MO.

The interface between a recording electrode and the electrolytic solution surrounding neurons has been modelled using the Hodgkin-Huxley model. Electronic limitations to invasive BCIs have been an active area of research in recent decades. While intracellular recordings of neurons reveal action potential voltages on the scale of hundreds of millivolts, chronic invasive BCIs rely on recording extracellular voltages which typically are three orders of magnitude smaller, existing at hundreds of microvolts. Further adding to the challenge of detecting signals on the scale of microvolts is the fact that the electrode-tissue interface has a high capacitance at small voltages. Due to the nature of these small signals, for BCI systems that incorporate functionality onto an integrated circuit, each electrode requires its own amplifier and ADC, which convert analog extracellular voltages into digital signals. Because a typical neuron action potential lasts for one millisecond, BCIs measuring spikes must have sampling rates ranging from 300 Hz to 5 kHz.
