cleverpebble··on Tesla vehicle in ‘Full Self-Driving’ beta mode ‘severely damaged’ after crash
Yea, it doesn't sound like the driver is truthful in the report. It is super easy to disengage autopilot - I do it all the time on accident. Just a little nudge of the wheel and it just gives up. Of course, this is assuming there isn't a firmware bug, but such a bug would have likely been reported publicly on the dozens of Tesla forums given it's severity
cleverpebble··on How to train large deep learning models as a startup
I definitely enjoyed reading your article!

Did you play around with any AI-specific accelerators (eg TPUs?)

Looking at some basic cost analysis from a stranger on the Internet - https://medium.com/bigdatarepublic/cost-comparison-of-deep-l... - you can probably get a decent price reduction in training, especially using preemptive instances (and perhaps a better pricing contract with Google/AWS)

It's kind of crazy how the shortage of GPUs is affecting pricing on physical devices. My RTX Titan I bought in 2019 for $2,499 runs almost $5k on Amazon and is in short supply. The Titan V options you linked (although I think theres a typo because you referred it it as a Titan X) is an option - but it is still super overpriced for it's performance. Of course, this will probably settle down in the next year or two, and by then there will be new GPUs that are ~2-4x flop/$ compared to the V100/A100.

In this case, the microphones are in fact on and processed by some relatively cheap (in terms of power consumption) algorithm whose sole purpose is detecting that phrase. Only after it detects that phrase does it start processing speech in any significant way
cleverpebble··on I Was Paralyzed by Severe Depression. Then Came Ketamine
Ketamine treatments are meant to be temporary and augmented with proper existing long-term treatments like SSRIs/SNRIs/TCAs/etc. After a few treatments, the long term antidepressants have had time to start working.
cleverpebble··on I Was Paralyzed by Severe Depression. Then Came Ketamine
ketamine has a lot of potential for abuse, especially for those with severe depression. it is why it is only allowed to be administered in a clinical setting.

Most trackers are 3rd parties that require you to go through their hosts. Additionally, these trackers are usually picked out by business analysts / product managers on different teams - so marketing my have their own tracking solution, sales might have their own, and engineering might have their own. Tends to be faster/easier to plop javascript on a page than engineering your own tracking/analytics pipeline at early stage startups
