This is the best way. Inline duct fan and a flex hose running out of your window (you can print an adapter/connector to fit perfectly). It works very well even if your enclosure is not airtight (and it shouldn't be when printing PLA since you want a constant stream of air getting inside for cooling) - just let negative pressure do its thing.

This is fantastic, thank you for your work! I'm excited to see this project combine a clean API in a popular language, with a fast online playground that requires no installation. Having played with OpenSCAD and CadQuery in the past, this feels like a big step forward.

Some suggestions (I'm sure you've already thought of most of these):

- It would be great to have notebook-like UI to isolate steps and allow faster partial rebuilds.

- live editing is great, but it'd be nice to automatically stop in-progress rebuild if another edit is made while it's computing. Right now it seems to always let a rebuild complete even if it's already out-of-date.

- Search on API/docs page would be really handy

- Face/vertex filtering API looks cleaner than CadQuery's, and I'm excited to try it out. In a lot of cases I would still really like to just be able to click on the model and get a reference in code. Even if it's just an index that would break if topology has changed. Auto-generating stable references/filters would be even better, when possible.

You can prefix a prompt for Whisper with a small text section containing desired vocab, and it will likely improve accuracy for that specific domain.

Whisper source is very readable, check out https://github.com/openai/whisper/blob/main/whisper/decoding...

Yes, thanks for the correction! In DIY keyboard community a microcontroller breakout board is often referred to as MCU which makes things confusing.

I love RP2040 (especially how circuit designer and firmware dev friendly it is) and even tried building my own MCU with it[1]

However I don't quite see the Bluetooth use case - RP2040 is not really a low power chip, making it pretty hard to use for a battery-powered IoT application. You'd need a pretty giant battery pack to make it last a long time.

Nordic's nrf52 is an order of magnitude better for a typical "sleep-burst transmit-sleep" cycle, and can be suspended to <5uA current. Pico W is $6, Seeed has a $10 nrf52 MCU, or you could get a "just hook up USB and power" bare module for $5-6.

Very cool, and excited to see more "Geometry as Code" tools getting built. In addition to comparing to OpenSCAD it'd also be awesome to see a comparison to CadQuery.

Cool idea, but it'd be great to add an explanation for choosing this over Stripe payment links (https://stripe.com/payments/payment-links). For Stripe, you can configure a redirect on success linking to your paid content so it should work for most use cases paidlink covers, no?

This is mostly nonsense, you can easily check for yourself.

Load up the OP's page with Chrome dev tools network tab open.

Connection start: 90ms (60ms of which is SSL handshake) Request/Response: 30ms request / 30ms response

So the whole post is about yak shaving not splitting the 30ms response portion of a request that already takes 5x that (150+ms).

Sure it's a bit faster, but your users will not notice the difference between a 14kb page and a 15kb page over https (which you hopefully have on).

For sure, nothing is 100% secure (and even with multiple U-locks an angle grinder will win out after a while). I've had a good experience with hexlox so far - they are super hard to remove without a key. Haven't had any theft issues in multiple years of parking around San Francisco.

While the overall point of simple racks being better definitely stands, the premise that a bike needs two locks is just silly and impractical. Get wheel locks for your bikes - pinhead, hexlox (my favorite), etc. If your wheels are secured to the frame you just need to lock the frame with one lock/chain.

Takes way less time to park and you dont need to lug multiple 5lb locks (unfortunately thats how heavy secure locks actually are).

Given that most old Android phones stop receiving security updates after only a couple years from purchase, you should probably not do anything that involves connecting them to your local network.

E-ink monitors are really cool (I've had a couple different ones for a while). However if your primary goal is reducing eye-strain, there are much better ways: https://twitter.com/levpopov/status/1466835595984977923

The nice thing about the current version is that it's just a straight-up HDMI peripheral so you don't have to worry about any security issues (Dasung's software is not exactly confidence inspiring, and I definitely would not touch any Android device shipped by them). USB-C would make it a lot more convenient for quickly plugging in though.

Thanks for linking to the report, it's interesting reading.

I think it largely confirms the point of my post though - we need independent certification labs in the US to make imported PPE usable. It is unclear what % of reported quality failures in that report were due to counterfeits. Now that the manufacturers have authenticity codes on their product we can hold manufacturers directly accountable for filtering performance.

The US does not even need to ramp up PPE production. Mask availability is good outside of the US, but you don't know if you are importing a fake one, unfortunately. This is solvable.

What's needed is additional certification labs and US-based quality control for imported N95/KN95 masks. It is very cheap to set up a new lab - all you need to test a mask is a ~$1000 sub-micron particle counter. Just keep buying samples of masks from various manufacturers and make sure they are not slipping on quality.

3M and Powecom now offer one-time-use authenticity code for masks they ship (see https://safeguard.3m.com) and other manufacturers will likely follow soon. This means that you don't have to worry about the middlemen doing importing and distribution swapping the product for counterfeit - all you need is a quality reputation score for manufacturers themselves, making the problem much easier.

This is of course should've all been done by the CDC and US Customs already but they are dropping the ball and doing only a limited amount testing. Maybe universities can step up and use their labs for testing?

--- Additional PSA for people reading this thread: you can buy reputable-looking KN95 masks from Office Depot(!) right now. It's an ear-loop design which is not ideal, but you could fix the rubberbands yourself easily.

Congrats on launching! yaseer, why does Axiom require a desktop app (vs running purely as a chrome extension)?

Paul, is there anything HN readers can do to help with this?

You can use Flowlingo on desktop/laptop at https://reader.getflowlingo.com - the mobile apps are definitely the most polished at this point which is why we’d prefer people start there first (we send a follow up email after registration with desktop info). Feel free to message us feedback/bugs at any time (tap “Help” and scroll to the bottom). Thanks!

Flowlingo dev here: Thanks for the suggestion - all this info is linked from app store pages (I'm guessing this is where the person above found it). Having a separate about page on the website is a great idea as well, we'll add that.

Gracias! Feel free to send us feedback in the app, any time (just tap “Help” and scroll to the bottom)

Almost everything in the app is free - including the tech news. There is a premium subscription to help our tiny team of two fund the development. Subscribers can practice with books (Flowlingo works with any .ePub file), and get more videos (in languages where we have a video library).

Great feedback. We plan on adding both - a notification, as well as a button to add and remove flashcards after tapping.

Hey - the phone number is just a convenience if you want to text the app store link to you phone (from the desktop landing page). You don't need a phone number to use Flowlingo, and we don't ask for anything other than email when you register.

Hey, thanks for the feedback. We definitely need to improve the app for Chinese - word tokenization is much harder here so we don't handle word selection well right now. Our app is most polished for languages like Spanish, French, German, Italian, and Russian.

Stay tuned though! We definitely want to make it work just as well for Chinese in the future!

Yep, that's exactly how Flowlingo works! We do the same for books and videos as well (native content in foreign language with ML translation tools to help you read/watch)

Hey, thanks for the feedback on the site being confusing. Will update to make it more clear!

All content is native content in the foreign language you are learning. Suppose you are learning Spanish - we'll show you a feed of popular news articles originally written in Spanish so you can practice by reading those. There is machine translation built in for words or sentences that you might need help with. We'll even automatically create flashcards for you for words you look up, to help you review with spaced repetition later.

When we say "browse any website" we mean that Flowlingo can be used as a general purpose browser - you can navigate to any website in Spanish and use the same learning tools to practice!

Check out https://www.getflowlingo.com - you can upload any epub and get translations when necessary to help you practice with a book.

Disclosure: I'm one of the app developers. Let me know what you think :)

As pointed out by folks on Gizmodo, the areas of the rectangles seem to have nothing to do with the number of servers listed inside (for example Intel's square is almost 4x the size of Rackspace, even though the server count is less than 2x).

Also, the numbers for Facebook are quite outdated.
