antoniuschan99··on Vietnamese property tycoon sentenced to death in $27B fraud case
I watched these three videos were pretty informative on the case:

antoniuschan99··on Low Cost Robot Arm
Mg400 is great for the price no issues. Very smooth! Check out this review video: https://youtu.be/6nGexb_i0aM?si=IP0E76MCGxrTrQEH

What payload are you looking for? Cartesian Gantry’s are your next bet if you want to handle higher loads. Eg. Epson vt6l is ~14k but I’m sure you can build a gantry system to handle higher loads for a bit less!

Dobot software sucks though, I ended up programming it in python. It’s definitely not on the same level as say a Kuka or Yaskawa. Epson seems like the best value out of all the higher end arms. Software looks good, the arms are built well, has a long history in industry, and price is decent

antoniuschan99··on Low Cost Robot Arm
I have a dobot mg400 but there are quite a few others: uFactory, elephant robotics, annin, dorna, epson (vt6L and their scaras), and lynxmotion is releasing their ses-v2.
antoniuschan99··on Vision Pro Teardown – Why those fake eyes look so weird
I think eventually when they have an m2 on an iphone then it can work but they’ll probably have to remove the fans somehow. Also the front display I wonder if it will go away one day. To reduce the weight further, cost, and with sunglasses you can’t see the persons eyes. However, it does differentiate the look from oculus
antoniuschan99··on Apple Vision Pro review
true i read the m2 on ipad 2 gets hot when playing games. And iPhones don’t have fans.

Maybe it’s apple trying to push the limits of this tech, a16 bionic compared to m2 is like 40% slower in the various computational performances so won’t be surprised to see the form factor show up in android devices soon for sure.

antoniuschan99··on Apple Vision Pro review
I think if it was an iphone accessory then it would have convinced more users because it would be $1000 since it’s just the display and sensors where iphone would drive all the compute
antoniuschan99··on Apple Vision Pro review
Was thinking they should have made it an accessory to the iphone instead. Have the iphone do all the compute and glasses just have sensors. It’s already wired because of the battery: it would weigh much less, iphone has magsafe portable battery for that extra juice, and would cost less (more adoption too)

Won’t be surprised if some android manufacturer like xiaomi release something like this.

Also, makes sense why Meta kept the form factor because they never had their own mobile device!

antoniuschan99··on Ask HN: Best open source and/or free EDA tooling
Aside from KiCad you can also look at EasyEda (think it’s from jlc), I’m still using diptrace (haven’t migrated to kiCad yet :$)

antoniuschan99··on GM says it's dropping Apple CarPlay and Android Auto because they're unsafe
I went ahead and googled if tesla uses android auto or carplay and apparently it doesn’t either. Neither does Rivian.

This is similar but should be enough to get you started! https://github.com/espressif/esp-csi

Wondering why there isn’t an option for a factory reset (eg. press and hold with a paperclip for 10 seconds)

antoniuschan99··on Nordic is getting involved in RISC-V
Nordic recently released news that their bluetooth power consumption is even lower (AirTags uses it). They also released a WiFi chip, but it's more like a co-processor so it's not really a competitor to ESP chips because you will still need a microcontroller. Espressif bluetooth isn't comparable because they still haven't gotten the battery consumption down to uA levels yet :$.

On the flip side, Esp is releasing the P4 which is just a microcontroller (no wifi or bluetooth so you'll need an ESP32 for co-processing) as there's things you can't currently do on esp32's such as mipi csi to interface with a wider range of camera modules easily.

Lastly, I recently discovered a lot of Chinese IoT stuff you get on Amazon (eg. Tuya and Tasmota) have migrated away from Espressif and use Beken (Google OpenBeken). I think it's more comparable to esp8266's but haven't found much info on it.

Risc-v is looking likely to be dominant in the iot segment.

antoniuschan99··on Nordic is getting involved in RISC-V
That's not true anymore. There was a shift to Beken Chips a year or two ago so a lot of your Amazon WiFi iot stuff uses that now (Tuya and Tasmota). Check out OpenBeken. I can't find much info on it but thinking it's cheaper than esp's probably more similar to esp8266 than esp32. Espressif chips are much more secure nowadays compared to the esp8266 days.
antoniuschan99··on Why doctors in America earn so much
Public community colleges primarily attract and accept students from the local community and are usually supported by local tax revenue - from Wikipedia.
antoniuschan99··on Are colonoscopies worth it?
It’s also good know that if you’re seeing bright red blood then it’s a higher chance it’s hemorrhoids whereas dark red you definitely should get it checked because it’s coming from inside your colon.

Also there’s supposedly a poop test called fecal occult blood test that has a high rate of detecting colorectal cancer that you do over the course of 3 years. I saw this on nhk Doctor's Insight: https://www3.nhk.or.jp/nhkworld/en/ondemand/video/2086035/

antoniuschan99··on Ask HN: What's the best way to become an independent software developer?
Another option aside from consulting or creating a product is to write software to trade stocks or crypto. Such as algorithmic trading.

antoniuschan99··on American Big Tech Has Enslaved Us [video]
I think web3 works for stuff like dropbox, so like dedentralized cloud computing services but has issues with things that tap into the real world like uber or airbnb in the sense that there needs to be a centralized place for support issues.
antoniuschan99··on American Big Tech Has Enslaved Us [video]
But you do need cloud for the marketplaces eg. Airbnb, Uber, Amazon. I mean previous iteration of that is Mail Order

Yea it’s a chatgpt output, when it comes to this type of information Google search results are good for finding definitions of glutamine for example but harder to get specific lists of things
antoniuschan99··on How BlackBerry failed to respond to the iPhone
They refused to have bbm on iphone and android so it was a big thing when they released it on the app and play stores in 2013. I remember they wanted to keep people locked into their phones to use bbm. But by then whatsapp started to take off so they had no choice.

antoniuschan99··on Ask HN: I’m an FCC Commissioner proposing regulation of IoT security updates
I would also push this onto the soc’s such as espressif, arduino, broadcom, nordic, arm, etc.

They are the ones that provide sdk’s for manufacturers to write firmware with ota firmware updates, flash encryption, secure boot, etc.

antoniuschan99··on Things I wish I knew before moving 50K lines of code to React Server Components
I started in 2010 with Java and JSP and initially thought the same thing. But after reading more about it, I see it as like foldable phones. We’re back to using foldable phones, but it’s totally different than before.

Also, I recall heavily using jQuery and Ajax to update parts of the page before Spa’s came along.
