i wrote something similar https://github.com/dwrtz/sink

it has some nice features:

- follows .gitignore patterns

- optional file watcher to regenerate the snapshot when files are changed

- supports glob patterns for filter/exclude

- can report token usage

- can use a config yaml file if you have complicated filter/exclude patterns

i find myself using it all the time now. it's great with claude projects

Yeah one needs to distinguish between the optimal state sequence and the optimal state at a particular time. In other words, a joint posterior (state trajectory up to now given all measurements up to now) vs a marginal posterior (state right now given all measurements up to now). the KF only gives you a marginal posterior. they are not the same

yeah the "filter" term means something different in the KF context and is confusing

filter: use measurements up to time t to estimate the state at time t

smooth: use past and future measurements to estimate the state at time t

predict: use measurements up to time t to estimate the state at time t+n

Yeah we decided to integrate with Teams because I had that exact experience in the past. I was at a company that decided "we're using Teams". We weren't allowed to install alternatives like Discord or Slack.

Teams itself has some limitations that are easy to improve upon. They have no way of doing a huddle/pop-in-style room. They screw up the presence signaling in a way that discourages pop-ins: if you join a call with someone your and the other participants' status is set to busy/unavailable. From other peoples' perspective this isn't very inviting, and doesn't indicate that the conversation is public. Teams also limits who can share screens to only 1 person at a time.

Sorry to hear you stopped working on your tool. My cofounder and I are working on a similar product (teraphone.app). We're focusing specifically on making a discord-like product for microsoft shops. I agree it's partly a culture thing. There's also an awareness issue. A lot of people don't know that pop-in style communication tools exist, especially outside the tech industry.

You may be thinking of put options. Buying calls is a bullish position.

What's wrong with push-to-talk?

Audio Weaver is a graphical tool for doing audio dsp. You use a drag-and-drop interface to configure your signal flow graph. When you "run" the system your graph is used to dynamically instantiate the necessary low level functions and compose them together. While the design is running you can do live tuning (changing gains, filter coefficients, delays, etc.). The low level functions have implementations on several architectures (PC, ARM Cortex-A and M, Tensilica HiFi 2 and 3, ADI SHARC, TI C66xx, plus a few more). This means that your signal flow graph is cross platform.

DISCLAIMER - I work for the company that makes Audio Weaver.

Awesome article! Here are two things that stuck out for me...

1.) In the first part of the article talking about decomposing a periodic signal into sinusoids of different frequencies - it would be more correct to refer to it as the Fourier _Series_, which is different from the transform.

2.) The image showing three sinusoids summing together into a non-period signal made me cringe (the sum is also periodic - that's the whole point of the Fourier Series).

It leaves you with an extra minute to decide if you're going to hit snooze again.

Higher inflation also means that it's cheaper for the U.S. government to borrow money. In fact, higher inflation is good for anyone who borrows money (people with mortgages, student loans, etc.) because they're effectively paying back less than they borrowed.

As erohead mentioned, the Octopus card is extremely successful, though it's limited to Hong Kong only.

Train stations in mainland China use something similar, though I'm basing this only my experience with one city, but a big one at that (Guangzhou).

Part of the reason why you aren't finding more accounts of successful NFC rollouts in Asia might be because you aren't searching in the local languages.

I would just like to point out that NFC is doing well in China, and in Hong Kong it's used brilliantly (public transportation, payments).

I think the reason it hasn't caught on here is because municipalities, malls, theme parks, etc., haven't embraced the technology, so there's no need for it to be in our phones.

A trick I use to really get in the zone is to blast a good song on repeat. I suspect the reason this works is that the repeating song blends with itself. You don't have the distinct transitions every 3-4 minutes, making it easy to lose track of time.

My team and I did this for a senior capstone project.
