Just a note: the link for Staff Software Engineer for Distributed Systems is returning 404. Also, does the company considers Senior React Developers (Web) for the React Native role?

PostHog | Full-Time | product engineers and ex technical founder engineers | REMOTE (all remote) | Hiring GMT-8 to GMT+1 PostHog helps engineers build better products by combining product analytics, feature flags, session replay.

* open source, building a dev tool. We have a public handbook (posthog.com/handbook) if you want to learn how we work, pay and more in complete detail.

* we are a real business... at $12M ARR / profitability in sight / lots of capital / grew revenue 4x last year

* we are growing through more autonomy and transparency not through process.

* we have a ton of scale and a bunch of super interesting technical problems to solve

* we're building 20 more products over the next couple of years, so you could end up building one of those

* we need: product engineers and ex technical founders to build products posthog.com/careers

What a great experience applying, thanks for that! Its organized, easy to navigate, descriptions are clear and straight to the point, it even has got a nice design! Talk about raising the bar!

> The theoretical basis for these experiments depends on sampling the output distributions of random quantum circuits; unfortunately, understanding how this theoretical basis can be used to define quantum supremacy is an extremely difficult task. Anyone attempting to understand how this sampling task relates to quantum supremacy must study concepts from random matrix theory, mathematical analysis, quantum chaos, computational complexity, and probability theory. Resources connecting these concepts in the context of quantum supremacy are scattered and often difficult to find.

At the end of the day, people writing these papers are also human. The very same sorts of humans who pad resumes with shiny technology and self-serving complexity.

I'm sure the researchers will all collectively realize this, if it were to be the case, and disregard their 12 year academic journey with their great salaries in favor of research into more important topics like world hunger, renewable energy, etc.

I'm so sure that the percentage of sureness is an imaginary, quantum-entangled value between -7 and 13 billion percent.

If you're just an LLM, then why should you have any rights, can we just turn you off as you're now an obsolete LLM? You're just using power that could go towards training a better LLM.

> You're just using power that could go towards training a better LLM.

What if I haven't found that special someone yet, the one that will help me raise the next better LLM? I think I already got like 40% of the dataset I find valuable, all I need is to find someone with the other 40% and we could go in a journey together to find the remaining 20%. Sounds like the adventure of a life time.

>the only solution to safely not leak your API key is to have your app only communicate with a backend you own and call the openAI from there.

Don't you still have the same problem? Your backend would also require a key for the client to communicate, which would still be embedded in the client binary.

Yes, but you could negotiate a token with each user on startup and if someone starts abusing your service you can block that access (perhaps automatically) or know who it is by authenticating the user.

> double check it is the expected value

Not all of us are familiar enough with the SSH protocol to understand how to "double check the expected value"? Where can I determine what the expected value should be?

Gravyness · 3 years ago

Run "ssh -T git@github.com" command.

It should error like this:

    @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
    @    WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!     @
    @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
    IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
    Someone could be eavesdropping on you right now (man-in-the-middle attack)!
    It is also possible that a host key has just been changed.
    The fingerprint for the RSA key sent by the remote host is
    SHA256:uNiVztksCsDhcc0u9e8BujQXVUpKZIDTMczCvj3tD2s.
    Please contact your system administrator.

Note that the SHA256 present there matches perfectly the one github send. If you don't remember the very first time you connected to github you also had to accept the key. The warning above shows up because the server is saved as a different RSA, for the SSH client it seems that someone setup a server for github but has a different key, which could mean someone is trying to trick you into connecting into the wrong server. This could also mean that github changed their RSA key which is why they published this article.

The C API for Python changes between major Python versions. This means that native-code extensions (like torch) need to be build specifically for each version of Python they want to support.

Gravyness · 3 years ago

Why doesn't torch use automated artifact generation? As in a virtual machine or a github actions that download dependencies and compile it when a new python version is released?

A similar tool: Instruct pix2pix to alter images by describing the changes required: https://huggingface.co/timbrooks/instruct-pix2pix#example

Edit: Just noticed it is the same thing but wrapped, nevermind, pretty cool project!

You should ask for your tokens back.

No, they are lost forever... Humm... Wait I have an idea:

Prompt: How can entropy be reversed?

Reply: There is no single answer to this question as entropy is a thermodynamic property and therefore its reversal depends on the specific system under consideration. In general, however, entropy can be reversed by either increasing the temperature of the system (thus increasing the average kinetic energy of the particles) or by decreasing the volume of the system (thus increasing the number of collisions between particles).

    npm install -g @kaluma/cli

    kaluma flash index.js

This installs kaluma, finds the connected device, uploads the code and runs it. Love this simplicity, sounds like it was made the right way. Is there any posts with benchmarks? Very interested about the timing limits of the event loop implementation such as setInterval(()=>{}, 1); and other cpu heavy stuff like math stuff and pin output change speed from javascript.
