shorts_theory··on NASA Just Launched Its New Perseverance Rover to Mars
How will the probe return the Martian samples? Is there going to be a round-trip mission to Mars in the future which will be able to take these samples back with it?
shorts_theory··on Airbus' self-flying plane just completed taxi, take-off, and landing tests
I don't ever recall seeing a train driver in my trips on Singapore's MRT either now that I think of it. Is this relatively new technology? Some of the older trains on the North East and Downtown MRT lines are at least a decade old, if not older. It would seem like that such tech should be ubiquitous in most cities with a good public transit system.
shorts_theory··on Moderna’s SARS-CoV-2 Vaccine Phase I Data
The Oxford vaccine (ChAdOx1) uses another vector virus called the adenovirus to deliver the coronavirus genes which the body can fight against. The issue is that some people might have pre-existing immunity to the adenovirus, making the vaccine ineffective. Since ChAdOx1 uses an adenovirus which infects chimpanzees, it is likely that most people will not have any pre-existing immunity to the vector virus. I guess the parent comment is referring to the fact that the body might develop immunity to the chimpanzee vector virus after two doses, making booster shots ineffective.
shorts_theory··on CUDA 11.0
I don't think there is an macOS machine which runs NVidia hardware anyway, is there?
shorts_theory··on Exciting Days for ARM Processors
From the limited data regarding the Tiger Lake benchmarks floating around, it could be just as much of a revelation as the Zen2 jump which you mentioned. The GPU is much more powerful than Icelake and the CPU seems to have benefited from the higher clock speeds possible from the more mature 10nm process. TDP is said to be the same, but it's hard to go by Intel watts until someone does a battery life test.
shorts_theory··on Those who exercise free speech should also defend it even when it’s offensive
This is something which I have become more aware of after reading "So You've Been Publicly Shamed" by Jon Ronson. I am now wary of posting any thoughts online which go against the tide of popular opinion. One of my takeaways from that book was that the cost of saying anything controversial online can be limitless. It's scary how mob "justice" and the rampant virtue signalling these days can ruin lives and careers. It's not just governments policing speech: the public is just as guilty.
shorts_theory··on Boston Dynamics shop: Spot Explorer
In fact, there is a startup called Exyn Technologies which tackles the problem of deploying autonomous drones in mines and other such dangerous environments (https://www.exyn.com/)!
shorts_theory··on Pine64 launches the cheapest Linux Tablet ever priced at just $99.99
I was working on a PyQt inventory management system for our robotics club (https://github.com/arc-bphc/sims-gui) back in undergrad. We weren't able to finish this project, but our plan was to have a Raspberry Pi 3 with Ubuntu MATE connected to a 7" touchscreen for running the inventory management software. This tablet would have made life much easier for us.
shorts_theory··on Pine64 launches the cheapest Linux Tablet ever priced at just $99.99
Excellent. This could be a great device as a Qt PoS or inventory management system.
shorts_theory··on Intel Discloses Lakefield CPUs Specifications
How much would the lack of AVX hurt performance apart from scientific computing? It's interesting to see Intel offering a chip with a clear focus on tablet computing, so the lack of AVX might not be so bad if the Tremont cores improve battery life significantly.
shorts_theory··on The Rise and Fall of BowieNet
I've been listening to Bowie's albums for years, but this is the first video interview I've ever seen of him. It struck me immediately how articulate and cogent he came across. Great video!
shorts_theory··on There will be no 'back to normal'
Great article. Sums up many of my concerns about the post-COVID19 world.
shorts_theory··on New iPhone SE
That's the thing. The battery is still healthy and it looks like it retains 90% of its capacity on the Battery Health setting page. I bought my SE very late into its lifecycle (June 2018), so I'm not sure why it's acting this way. I have had a problem with the phone rapidly losing charge in cold weather though. Did you also have severe battery drain on your SE on iOS 13 before replacing the battery?
shorts_theory··on New iPhone SE
I would probably upgrade just for the battery. iOS 13 is very smooth on my SE but the battery is just nuked without battery saver on all the time.
shorts_theory··on Ask HN: What are you learning?
As a beginner, I really like Justin Guitar (https://www.justinguitar.com/site-map-and-lesson-structure). But I'd love to know what other great resources are out there!
shorts_theory··on The End of Starsky Robotics
To my knowledge, Singapore's SBS Transit loses money on their transportation business, but makes it up with their construction projects.
shorts_theory··on Facebook Now Lets You Turn Any 2D Photo into a 3D Image Using AI
Why would it need an "iPhone 7 or above" when the depth map is calculated on FB's servers?
shorts_theory··on Mass layoffs reported after Starsky Robotics fails to find buyer, investors
> “We beat Waymo. We beat all the big OEMs. We’ve beat just about the whole industry,” says Stefan Seltz-Axmacher, founder and CEO of the San Francisco based start-up.

I find this statement pretty disingenuous when Waymo is trying to tackle the part of the problem Starsky isn't able to solve with their own self-driving tech - driving without a human in the loop for the last mile.

shorts_theory··on 95th percentile isn't that hard to reach
Spelunky is an absolutely terrific and soul-crushing game. Though I'm not sure if it's a good example here because most of the mechanics (apart from the absolutely ridiculously arcane series of things you need to do to go Hell) are designed around being amenable to self-discovery. The shortcuts system for each world is very useful for learning all the weird situations which can result in death.
shorts_theory··on Satellaview
I really love that Nintendo did something like Satellaview, and it's always been something that has struck me as a niche product that was far ahead of its time. It's too bad that we will never be able to experience what using the Satellaview was like (admittedly, probably pretty slow and crappy), but at the time I can only imagine it would have felt quite novel.
shorts_theory··on I Miss the Old Internet
I've been doing this quite a lot for finding useful opinions or reviews on products. Reddit comments have a surprising consistency when it comes to tone and objectiveness which I've come to appreciate when I need a second opinion on something.
shorts_theory··on Ask HN: How do you share/organize knowledge at work and life?
I use OneNote on KDE Neon in a Windows 10 virtualbox. Yes, it's not the most efficient but I have found this approach much faster than using the sluggish web UI for OneNote. I also use my Windows 10 virtualbox for the rest of the MS Office suite through a university subscription, so I feel it justifies the 30GB of disk space it takes.
shorts_theory··on What it was like to fly the baddest airplane
It’s one of the greatest spaceflight books I’ve read. It’s movie still holds up very well even today.
shorts_theory··on 94k Bitcoin (1B USD) transferred from unknown wallet to unknown wallet
This is the part which confuses me about Bitcoin the most. It's meant to be anonymous, yet with some diligent data mining, it can become pretty clear who's who from their spending patterns by observing the ledger. How is that remotely anonymous?
shorts_theory··on Human speech may have a universal transmission rate: 39 bits per second
That's interesting. If you're talking about Hello Internet, I enjoy listening to them at 1x. I find it quite relaxing to listen to passively.
shorts_theory··on Backing Up My Kindle Ebooks (2018)
I'm pretty surprised. I've used Calibre's inbuilt EPUB -> AZW3/MOBI converter for hundreds of books to left-align them for my Kindle. The only books where the formatting was messed up were the ones in which the EPUB wasn't formatted properly in the first place.

I'm also interested to know more about why Calibre destructively converts EPUBs instead of making a copy to work on instead. Do you have any sources for how this works?

shorts_theory··on Vintage video game cartridges with built-in modems
I love articles like these. To markchristian, I was wondering if you have any informatinon about the SNES Satellaview unit and how the experience of playing Satellaview games was different from playing cartridge games back in the day? Satellaview always seemed much ahead of its time and I feel like it hasn't gotten the recognition it deserves, though that's probably because it was Japan only.
shorts_theory··on Microsoft Flight Simulator
I'm so glad that this is a thing now! My first memories of MSFS was FS98, which was one of the few games which ran acceptably on our dated 531MHz Pentium 3 desktop. I remember getting FS2004 a few years after and I was never so simultaneously excited and disappointed to play it when our poor desktop could only sputter out 4-5FPS with all the settings turned down to the absolute minimum.

Years later when we upgraded to a more acceptable desktop, I spent hours of free time in middle school trawling simviation for the most absurd addons, including a Flying Hawk, a cruise ship, a space shuttle, and a BMW 760Li, because why not? My FS2004 install swelled from its initial 3GB to 12GB with all my addons. I've done a countless number of commercial flights and became a lot better at landings thanks to the FSPassengers mod which added some life to the barren FS2004 world, complete with options to serve your passengers drinks and listen to their screams when going stalling into a free-fall :)

shorts_theory··on Where Has the Magic Gone?
I've felt this too. During my learning phase with the Arduino, I had hastily bought a bunch of sensors and random pieces of hardware with some ideas but no cohesive plan of what I was going to do with it all. After a stint at my college's robotics club, I had a much better idea of how everything worked but I felt drained of the vague and exciting ideas which made me buy all the hardware in the first place.
shorts_theory··on Where Has the Magic Gone?
OP and writer here, thanks for sharing this. I enjoyed that piece and the sentiment really resonates with me.
