<p>It's true that turbopuffer does vector search, though it also does BM25.<p>The biggest difference at a low level is that turbopuffer records have unique primary keys, and can be updated, like in a normal database. Old records that were overwritten won't be returned in searches. The LSM tree storage engine is used to achieve this. The LSM tree also enables maintenance of global indexes that can be used for efficient retrieval without any time-based filter.<p>Quickwit records are immutable. You can't overwrite a record (well, you can, but overwritten records will also be returned in searches). The data files it produces are organized into a time series, and if you don't pass a time-based filter it has to look at every file.</p>

<p>Proper brokerages will pay you to lend your securities, transparently disclose their programs, and require consent. For example:<p>- <a href="https://www.interactivebrokers.com/en/pricing/stock-yield-enhancement-program.php" rel="nofollow">https://www.interactivebrokers.com/en/pricing/stock-yield-en...</a><p>- <a href="https://www.fidelity.com/trading/fully-paid-lending" rel="nofollow">https://www.fidelity.com/trading/fully-paid-lending</a><p>Some brokerages lend out spare cash (and pay a transparent interest rate, and are subject to strict reserve requirements) but the majority of assets controlled by a typical brokerage are securities. FTX assets were all subject to their leverage strategies, with no specific reserve.</p>

<p>JPEG XL implements lossless image compression, but that's definitely not the most interesting feature. It also implements lossless JPEG recompression. So your existing JPEGs can be served with ~20% less bandwidth, without quality loss.<p>Unlike AVIF, JPEG XL also has advanced progressive delivery features, which is useful for the web. And if you look at the testing described in the post, JPEG XL also achieved higher subjective quality per compressed bit, despite having a faster encoder.</p>

<p>Production audio and video recorders generate or intake an SMPTE timecode signal, and stamp recordings with this timecode.<p>This timecode format is a timestamp with seconds resolution plus a frame count within each second. To properly sync, all the timecode generators must use the same framerate. In other words, the audio recorder’s timecode framerate needs to match the camera.</p>

<p>In theory having fewer repeaters improves latency, probably in the range of 100ns per repeater. I don't know how much of a practical effect that has, likely very minimal with modern implementations.<p>Either way it's more sensible to build high throughput microwave networks given the tiny amount of shortwave bandwidth we have.</p>

<p>Shortwave radio can be transmitted around the curve of Earth by ionospheric reflection and refraction so fewer repeaters are needed. This allows crossing vast oceans where microwave infrastructure might not be possible.<p>As you say the downside is available bandwidth and throughput.</p>

<p>According to the sources I've read, it uses a tiled rasterizing architecture but it's not deferred in the same way as typical mobile TBDR that bins all vertexes before starting rasterization, deferring all rasterization after all vertex generation, and flushing each tile to the framebuffer once.<p>NV seems to rasterize vertexes in small batches (i.e. immediately) but buffers the rasterizer output on die in tiles. There can still be significant overlap between vertex generation and rasterization. Those tiles are flushed to the framebuffer, potentially before they are fully rendered, and potentially multiple times per draw call depending on the vertex ordering. They do some primitive reordering to try to avoid flushing as much, but it's not a full deferred architecture.</p>

<p>> football player style contracts for engineers, where you are tied in to a team for N years, and with a requirement that another team has to pay big money for your contract if they want you to transfer?<p>i.e. golden handcuff equity grants with vesting schedules? Top performers in highly demanded areas can have some or all of their remaining equity bought out.<p>It definitely ties the value of the contract to the stock price. In a way the company is leveraging its stock - significant declines hurt talent retention, and significant gains help it.</p>

<p>I’m not sure I understand this argument. Why can’t users simply use the mouse wirelessly even if it’s possible to use in a wired way. Are you claiming that people would end up leaving the mouse plugged in, like they do with the trackpad? If the point is that using a wireless mouse is a better experience, then why wouldn’t people use it wirelessly except to charge?<p>I have an Apple keyboard and trackpad that I use at my TV wirelessly but have benefited from the ability to use while charging a few times when the battery died. Doesn’t stop me from using it wirelessly 99% of the time because the experience is better.<p>By the way, I have an older phone I leave plugged in all the time by my bed, the battery life on it has deteriorated but it works perfectly for music.</p>

<p>Apple’s own wireless trackpad and wireless keyboards work while being plugged in.<p>I think the sleek visual and ergonomic design specifically resulted in the charge port being put on the bottom, which resulted in their decision to disable the mouse when it’s charging. Not the other way around.</p>
