> The ultimate dream protocol is one in which a sender just encodes bits in a certain way such that the receiver will get them, and puts them on the line without any handshaking or synchronization.

This is a recipe for DDoS.

Some handshaking is always necessary. You can minimize it, but you can't get rid of it.

Rather, I find it rich how much these schools bend over backwards to claim they’re ensuring equity and progressive morals in their admissions while simultaneously maintaining the regressive and archaic practice of legacy admits, which are implicitly racist in favor of (the most privileged subset of) white people.

One camera produces millions of bytes of data every single frame, an ultrasonic sensor is useful producing just 1 or 2 bytes of data in the same time span. (distance to something within the sensor's cone).

So it seems like a totally ridiculous argument that ultrasonic sensors create some kind of data processing overload.

An ultrasonic sensor makes it possible to implement incredibly simple and reliable safety features with well known performance characteristics. Processing an image with ML to produce the same effect has tons of edge cases where it might not work, and nobody knows when it won't work, and every update to the system could introduce regressions.

It's why they had to disable certain features when they got rid of the ultrasonic sensors. Those features may come back some day, but I bet they'll never be as reliable, and certainly won't be as predictable.

The interesting part to me was that they used specifically a 64kbps example, not a higher bitrate that would be more appropriate for music listening. Just speculating, but if they managed to get 10x higher compression rate compared to 64kbps MP3, could they achieve an even higher compression rate when compared to 320kbps MP3? If the algorithm is so good that it can compress audio down to 6kbps with just a few artifacts, would it sound almost good at 12kbps? 24kbps?

Between this effort and the recently announced Google-led multi-channel/immersive audio codec initiative, I am pretty excited about the future of audio streaming and distribution.

From my DARPA Grand Challenge days, I used to have an Eaton VORAD automotive radar. This was an early design - 24GHZ, 1 scanning axis. It could see cars, but not bicycles, at least not reliably. For several months, I had one pointed out the window of my house, looking at an intersection. So I had a V-shaped wedge on screen, and could watch the cars go by.

It's a Doppler radar, so you don't get any info from things stationary relative to the radar, but you do get range and range rate. And the quality of that data is independent of distance. We used it mainly as a backup system for the world model built with LIDAR and (to a very limited extent) vision. The VORAD data could lower the speed limit for the rest of the system, and if a collision was about to happen, it would slam on the brakes independently of the world model.

The big problem with coarse automotive radar is that it can detect targets, but doesn't tell you much about them. Cars, trash cans, and metal road debris all look about the same. There's also a lot of trouble from big flat metal surfaces being mirrors for radar. We were willing to accept slowing down for ambiguous cases until the other sensors could get a good look. Drivers hate that if road-oriented systems do it.

Modern units are up around 70-80GHz and often have 2D scanning, which is a big help. I haven't seen the output from a modern automotive radar. I was expecting that by now, low cost millimeter microwave systems (200-300GHz) would be available, providing detailed images somewhat coarser than you can get with light. You get range and range rate, and you can usually steer the beam electronically rather than mechanically. The technology exists to get high-resolution radar images, but is mostly used for scanning people for weapons at checkpoints. It hasn't become cheap yet.

I have the same issue with Solarized. I need something with just a little more contrast.

One Dark is more like what I want.

But even that's not perfect. The color for comments (as with many dark themes) is too dim. Comments shouldn't stand out, but they should also be easy to read when needed. I think that Visual Studio's dark color scheme actually does great there. The green comments separate themselves well from the code, don't draw too much attention to themselves, and they're still clear when you're trying to read them.

It seems pretty obvious to me that you never lived through the bad old days when compilers all did whatever they wanted.

Tell me again how much you care about C++20 when a library with a feature you want uses it but your toolchain doesn't support it.
I found that 16GB on my laptop provided only enough memory for two app VMs. I don't understand how people are keeping all these VMs without constantly shutting them down and starting them up again.

I was using zswap to cut the memory load of each VM, which made it sort of tolerable. When a VM gets to using too much RAM, streaks and visual artifacts start to show up in windows and desktop decorations, eventually filling them with random noise, and then there is nothing to do but shut the VM, and often the whole machine, down.

I resent systemd burning hundreds of MB in each VM for, mostly, nothing of any value. You can "systemctl disable" things like wpa_supplicant, but it doesn't help much.

I have finally got another laptop with 32GB, expandable to 64GB. But suspend/resume doesn't work on it -- screen just goes black, until power-off -- nor an external HDMI monitor. I have to hope future kernel releases will fix these.
Kind of like an iPad? I'm being facetious here, but the broader point could be that what you describe is better suited for a portable form factor than for a desktop computer, where most users will favor performance over a fanless, sealed design.

It's different because feature-wise all Mastodon instances are quite similar (some might have bigger character limit etc.)

> There are trade offs because while you gain different views of the environment from different sensors, the fusion becomes more complicated and has to be sorted out in software reliably in real-time.

If you're against having multiple sensors though, the rational conclusion would be to just have one sensor, but Tesla would be the first to tell you that one of the advantages their cars have over human drivers is they have multiple cameras looking at the scene already.

You already have a sensor fusion problem. Certainly more sensors add some complexity to the problem. However, if you have one sensor that is uncertain about what it is seeing, having multiple other sensors, particularly ones with different modalities that might not have problems in the same circumstance, it sure makes it a lot easier to reliably get to a good answer in real-time. Sure, in unique circumstances, you could have increased confusion, but you're far more likely to have increased clarity.
> Go talk to ESS, a non-retail technology not being available at retail isn't an indicator of anything.

Well, it is. Anyone can produce lithium batteries. Whereas with the magical batteries it's "ESS Inc is the only manufacturer and holder of patents on its flow batteries".[1]

Which is not how you want to quickly ramp up production and solve storage.

The targeted production is 750MWh per year which is nothing, really.

Their biggest planned project is to have 400MWh in Australia by 2026. I'll let you do the math on how laughable that is by yourself: https://www.energy.gov.au/data/renewables

Iron redox batteries as they currently are don't really exist: the production is low, and locked behind the patent lock of a single company.

The article is obviously wrong. Experience means exercise and exercise helps you to get better in any human endeavor not just programing.

How well a person learning programing since two weeks does when compared to someone who did it for two years?

Also programming means problem solving. Practical programing is not hard the way leet code problems are, practical programming isn't typically requiring you find a very smart algorithm and a very clever approach. Practical programing is hard because it requires massive knowledge, it requires tying those pieces of knowledge together and it requires a very good low level understanding of how systems work.

Being very good at algorithms and data structures will help sometimes - and I enjoy algorithms and data structures and even some of the abstract leet code problems - but knowing that is far from enough, like knowing a programming language is far from enough.

Algorithms are tools, data structures are tools, programming languages are tools, libraries are tools, frameworks are tools, system design, databases, build tools, Ides, debuggers, profilers, cloud, protocols, hardware architecture are all tools. You have to know how to use them and when and why.
Elon might not understand software business in the modern age. Unlike Tesla or SpaceX, there is little unique tech to serve as a moat.

The companies rely on engineers on staff to keep the lights on. And crucially, they have 1000 other options who will pay as well without any relocation - unlike a specialist in rocket science or other hard engineering.
Ironically, this article against procrastination may itself be a form of procrastination. The author's current company seems to have fallen on hard times; its Glassdoor reviews indicate executive mismanagement. A situation that would encourage most managers, especially a CTO, to procrastinate.

Tesla doesn’t release any data. But there are community trackers [1] that puts the disengagement rate in the single digit miles. In comparison, Waymo and Cruise had a rate of roughly 30,000 miles/disengagement according to CA DMV data. That’s how much worse Tesla FSD is.

I'm simply pointing out that if one objects to renewables because scaling has not been demonstrated, and also advocates nuclear, then one is being a hypocrite -- because nuclear also lacks demonstration of the necessary scaling.

I don't think the argument that scaling has not been demonstrated is a strong argument, unless there is a good reason to think the scaling won't work. There isn't a good reason to think that for renewables overall. In particular: limits on area are not sufficient, and limitations on particular storage technologies (say, from materials requirements) also fail, since there are many different storage technologies, some of which require no rare materials at all.

> While such techniques have been explored before for speech, we are the first to make it work for 48 kHz sampled stereo audio (i.e., CD quality), which is the standard for music distribution.

Reading this extremely charitably, I think the contrast is supposed to be to speech which is normally uses much smaller sample rates. E.g. AMR-WB samples at 16 kHz. Speex, back in the day, supported up to 32 kHz.

Full quality digitally distributed audio is often sampled at 48 kHz (e.g. Opus - the default audio codec on YouTube and many other sources), so I think "CD quality" is just supposed to emphasize that it's full-band rather than wide band or narrow band.

Twitter is gonna have a hard time differentiating itself as a job now. Why work for Elon who treats people like this? Maybe that one somewhat niche political/ideological faction in software will be more likely. Lifestyle devs (most of them)? Nah - there's 10 chiller options out there.

I don't think there's enough true believers out there to sustain even normal dev turnover of 1-3y. Maybe Elon will have to pay even more money on salaries to stand a chance. Or he'll give up since he seems a little Dunning-Kruger on this venture as SV CEO.
It is possible, my question may be why would you want that? European companies generally pay less then US or Asian companies.

Lol this doesn't make any sense. The dynamic range of a fully sunlit California highway during noon in the summer (I.e. the brightness reading of the darket vs the brightest spot) is wayyyy higher than any existing sensor. You cannot ignore exposure, you have to choose which part of the scene you want within the brightness range that your camera sensor can capture. You will have areas of the scene that clip, in other words areas of the scene that are pure black or white with no data.

You can do bracketed exposures, but that's literally the opposite of ignoring exposure.
