ghop02on Nine US states are teaming up to accelerate the adoption of heat pumps

15 SEER relates to cooling efficiency, what is its HSPF rating?

just need a "follow who you followed on twitter" feature

ghop02on Function pipelines: Building functional programming into PostgreSQL

While I agree the partition syntax may not be super straightforward, adding a new operator for another way to sort, sum, and abs etc. seems like chaos

ghop02on NYC to mandate proof of vaccination for many indoor settings

There have been numerous studies showing that 2 doses elicits higher antibody responses than natural immunity alone, here's an example of one:

ghop02on Israel data reportedly shows efficacy drop of Pfizer-BioNTech for delta variant

I don't quite understand the "censorship" argument. Of course governments and public health officials are going to push the most effective tools we have to save as many lives as possible.

What is censorship in this case? Not spreading debunked or poorly-supported claims?

True censorship would've been something like keeping hush the rare blood-clotting incidents with J&J. But there are so many studies across so many countries that are freely available to read and be informed by.

Even the claims of twitter/other social media censoring don't hold water for me. Extraordinary claims should require extraordinary proof imo

ghop02on Tensorflow 2.0

https://groups.google.com/a/tensorflow.org/forum/#!topic/dev...

Ah I guess it's on the way but not fully there yet

ghop02on Tensorflow 2.0

Core ML 3 adds a ton of new operations, including control flow support.

ghop02on Tensorflow 2.0

They're (slowly) making this better. Starting with 1.15, there is only one tensorflow pip package, no tensorflow/tensorflow-gpu hell any longer.

ghop02on Tensorflow 2.0

> This is also the last major release of multi-backend Keras. Going forward, we recommend that users consider switching their Keras code to tf.keras in TensorFlow 2.0

ghop02on Why Medium Sucks

I would love to see Medium profiles untethered from the actual medium site itself.

I love that you can post on your "personal" page, another publisher and not need to make a new account.

Are there any solutions out there that let you keep a consistent profile across multiple blogs?

ghop02on JavaScript is now required to sign in to Google

What many of the comments seem to be missing is that you don't need to enable javascript on all google sites, only the sign-in page. With that in mind, I don't think there needs to be as much concern as we're seeing here.

ghop02on PeerTube, a free and federated video platform reaches 1.0

I might not be understanding correctly, but it doesn't seem like you're being paid for the content you're hosting on PeerTube.

The model feels different than a webserver where you are either hosting your own content (and paying for that) or charging others to host their content on your server. Or am I misunderstanding?

ghop02on PeerTube, a free and federated video platform reaches 1.0

Seems like a great idea, but not much activity (from what I can see). How is this model sustainable? Do I have any incentive to setup a PeerTube server?

ghop02on Listen to a SIM-Jacking, Account-Stealing Ransom

2FA security aside, it really is remarkable how Jared was able to talk the hacker down. We seem to really undervalue those sorts of social skills. Jared's one conversation could have saved hundreds of thousands of dollars (for himself and others).

ghop02on iOS 12 Core ML Benchmarks

It's my understanding that the neural engine API wasn't actually exposed to Core ML until the iPhone XS. The GPU is the important factor for performance of those models

ghop02on Ask HN: Have you ever chosen Postgres over Mongo and regretted it?

Syncing smaller databases between devices seems to be the best use case of CouchDB.

However, Couch is extremely difficult to manage at scale, especially when managing indexes on top of documents. The index generation was extremely slow and wasn't able to take advantage of beefier hardware at all. Deploying updates to indexes had to be done extremely carefully as it will rebuild the entire index and lock reads from that index in the meantime.

Iterating through GB of documents takes a wildly long amount of time, especially if other operations such as indexing updates are happening.

Furthermore it had scary failure modes. There were many times that a couch instance would die with documents cached in memory but not yet written to disk, even though couch had returned a successful document write. We found that documents we thought existed were lost forever during this blip.

ghop02on Free Ethereum spam bots are ravaging Twitter

You know there's a problem when any prominent crypto figure has to put "not giving away free Eth" in their twitter name to help combat the spam.

ghop02on DensePose: Dense Human Pose Estimation in the Wild

This is awesome! Will the code eventually be available on detectron?

ghop02on AI Learning How to Play Pong in RealTime – PyTorch

Ah, I'm new to tensorboard. The help link in tensorboard was broken. But that link works :) very cool!

ghop02on AI Learning How to Play Pong in RealTime – PyTorch

The help link doesn't work for me, did the github repo change?

ghop02on Facebook may lose 80% of users by 2017, say Princeton researchers

Using an SIR model seems a shady approach for this model. The model inherently assumes an amount of time where a person is "infectious." They modified the traditional SIR model, Also, they never allow migration from the Recovered class to the Susceptible class again, meaning that once a person stops using Facebook, they will never use it again. It seems to not take into account age buckets (where Facebook may be more "infectious" with different age groups).
