- Comment on FFmpeg devs boast of up to 94x performance boost after implementing handwritten AVX-512 assembly code 1 week ago:
Yeah, but Intel charges you $200 more for the -K sku so you can find out the same applies to Intel :)

Then this is your reminder that ALL AMD CPUs are Unlocked and support overclocking…
- Comment on Bike Manufacturers Are Making Bikes Less Repairable 4 weeks ago:
Cheap E-Bikes seem more easy if you are willing to get into the wiring. A lot of them use very similar parts in terms of Hub Motor, Controller, Battery
- Comment on How much current can I safely pull from an ESP8266? 2 months ago:
5V will be pulled directly from 5V supply
The chip you are concerned about getting warm I believe is your 3.3V regulator.
I would ensure your transistor has some resistors to ensure you are not drawing more current than required from the 3.3V supply
If that is all good then I will remind you of a few things
- The board you have is a clone (I use them… but they can be dubious)
- The ESP8266 requires a certain amount of current to run which will cause the chip in question to generate heat all on its own
- The chip in question appears to be an LDO which will mean going from 5v to 3.3v is done by turning the excess voltage into heat.
I couldn’t find an exact Datasheet but I am led to believe that the chip is a clone of this www.sunrom.com/download/670.pdf
Which I found on this store page sunrom.com/…/rt9193-33gb-rt9193-33pb-sot23-5-300m…
And here is a wiki entry incase you are curious about Voltage Regulators and the such en.wikipedia.org/wiki/Low-dropout_regulator
- Comment on Minecraft. Family guy, even. 3 months ago:
Old school YouTubers started and sold Maker Studios. I think ShayCarl, Lisa Nova and Kassam G are some that were part of that.
- Comment on Google Chrome ships a default, hidden extension that allows code on *.google.com access to private APIs, including your current CPU usage 4 months ago:
Google does a lot of standards breaking things.
Like allowing a link on Google Apps Marketplace to open a new window (like popup) with POST instead of GET. (This pretty much ensures that buying an app will fail for browsers that follow the spec)
- Comment on The problem with standalone VR and "spatial computing" 9 months ago:
I was hoping for free :( BUT $150 for Zeiss lenses is pretty ok price wise. (especially when we are complaining about $150 onto of a $3500 device)

Looks like I would need a newer Palm Device palmdb.net/app/zdoomz but it does have Tetris

Good eye!! I tried to make it clear but that was the best I was going to get.

- Comment on Ubiquiti Users Somehow Being Fed Access to Strangers' Security Cameras 10 months ago:
Best place to start if you’re taking security seriously; Implementing file encryption for example has to start with “I would rather that I myself potentially lose access to this data than for it to possibly fall into another person’s hands.”
- Comment on YouTube's plan backfires, people are installing better ad blockers 1 year ago:
I have stopthemadness setup in my safari browser to redirect all YouTube links to invidious…. I watch less YouTube that way
