Show HN: Space4 – A workplace to help with staying focused and being productive
We’re the founders of Substack, we just launched an iOS app. AUA
Hi! This is Chris Best, Hamish McKenzie, and Jairaj Sethi, the founders of Substack, with Sachin Monga, the head of product. Yesterday, we launched an iOS app for Substack, so you can read all your Substack subscriptions in one place, with no distractions.<p>Readers have been tweeting at us for years now to ask when we’d have an app. We’ve long wanted one too, and we suddenly got the manpower to be able to build a good one when we acquired Sachin’s company Cocoon (W19) last year.<p>Soon after starting Substack, we found it easiest to explain what we do as “We make it simple to start a paid newsletter.” Even then, a Substack was more than just an email newsletter: it was also a blog, and it could host embedded video and audio, and people could leave comments and participate in discussion threads. But the term “newsletter” was useful shorthand because everyone kind of got what that meant. All along, though, we’ve been quietly building the tools for what we call “personal media empires,” encompassing different media formats (natively) and community discussion (which we intend to make better and better).<p>By a similar token, right from the start we’ve been intending for the company to do more than just provide subscription publishing tools. We’re excited by the vision of Substack becoming a network, where writers and readers benefit from being part of a larger ecosystem. For writers, it means they can be discovered by readers who might not otherwise have found them. For readers, it means being able to connect directly with writers and other readers and to explore a universe of great work.<p>The app is a key part of the network vision. Nothing changes in terms of writers and readers being in control. The writers still own their mailing lists, content, and IP and can take it all with them anytime they want. Anyone who signs up to a Substack through the app still goes on to that mailing list. And readers still get to choose what appears in their “inbox,” with the power to subscribe and unsubscribe from whatever they want (you can also add any RSS feed into the app via reader.substack.com). But now we’ll have more and better ways to surface recommendations from writers and readers, to show people’s profiles, and to deliver notifications inside and outside of the app.<p>This is just a start for the Substack app. We want to keep improving it, so please give us feedback and ask us the hard questions. What do you think we’re doing wrong? What could be better? What could be great? What might we not have thought of?<p>We’re here for the next couple hours. Ask us anything.<p><a href="https://on.substack.com/p/substackapp" rel="nofollow">https://on.substack.com/p/substackapp</a>

Show HN: Open source machine learning inference accelerators on FPGA
Tom from Tensil here - happy to answer questions!<p>We developed Tensil to bring custom ML accelerators to people who don't have the resources of companies like Google, Facebook and Tesla. Currently, we're focused on supporting convolutional neural network inference on edge FPGA (field programmable gate array) platforms, but we aim to support all model architectures on a wide variety of fabrics for both training and inference.<p>Tensil is different from other ML accelerators in that it is open source and really easy to use. For example, you can generate a custom accelerator with one command:<p><pre><code> $ tensil rtl --arch <my_architecture>
</code></pre>
You can compile your ML model targeting that accelerator like so:<p><pre><code> $ tensil compile --arch <my_architecture> --model <my_model>`
</code></pre>
Running your model on FPGA is as simple as doing the following:<p><pre><code> $ tcu.load_model(<compiled_model>)
$ outputs = tcu.run(inputs)
</code></pre>
The accelerator generator was developed in Chisel and we built our own parametrizable compiler to target it. The link in the post takes you to the documentation, and here's a link to the Github repository: <a href="https://github.com/tensil-ai/tensil/" rel="nofollow">https://github.com/tensil-ai/tensil/</a>

Show HN: 2D Game engine and editor for Windows and Linux
Hello HN,<p>Just wanted to show this little 2D game engine that I've been working on for some time (around 2 years on the editor part, longer on some of the components).<p>It's quite full featured but obviously this a project of such magnitude already that the work never really ends. That being said it's definitely already at a point where games can made and published. The editor runs natively on Windows and Linux using Qt5. The games can run on both Win and Linux as well as on WASM with WebGL.<p>Feature wise there's a bunch of the stuff you'd expect.<p>Audio, graphics, scripting, animation+entity+gameplay systems, physics and UI are all there. Scripting is through sol3 + Lua, physics with Box2D. Audio, graphics, UI and game play stuff is all done by me.<p>License is currently GPL.<p>Source code is on github <a href="https://github.com/ensisoft/gamestudio" rel="nofollow">https://github.com/ensisoft/gamestudio</a><p>Some games are available on my site at

Show HN: World’s first £3 flat fee (0% FX markup) money transfer service
Good morning everyone! My co-founder and I recently moved to the UK after working at Robinhood for over 5 years. We were stunned at the fees it was costing us to move money across borders with existing fintech solutions, so we decided to start Atlantic Money - the world’s first fixed fee (with no FX markup) money transfer product. For £3 you can transfer up to £1M. Let us know if you have any questions!

Show HN: I wrote a load balancer with XDP and Go
Facebook's Katran looked too scary (and I don't do C++), so I thought I would investigate using XDP/eBPF to redirect packets at high speed and Go to do the control plane work of health-checking backed servers and managing configuration. With luck the resulting binary should be easy to deploy by non-developers.<p>It's still not mature, but seems to work. Code was written in a very exploratory manner, and I'm not a developer
so it is quite shocking at the moment, but I aim to improve it. It is intended to be horizontally scalable with ECMP and has been tested on service providing 40Gb/s with a single (hardware) node at ~30% CPU utilisation.

Show HN: Prodscape.net – Map your mobile app
Hello HN,<p>Long-time lurker, first-time poster here. I've created a service that creates a "flow map" of your mobile app.<p>Check it out at: <a href="https://prodscape.net" rel="nofollow">https://prodscape.net</a>.<p>The goal is to reduce last-minute regressions, promote holistic discussion, and help develop more ownership within an organization. This is something that I would have liked to have had when I was working at a big company.<p>Some caveats:<p><pre><code> 1.) Only iOS is currently supported but Android-support will be coming soon.
2.) You need a developer-signed IPA file (see the guide on creating an IPA file here: https://prodscape.net/finding-ipa.html).
</code></pre>
I would appreciate your thoughts on:<p><pre><code> 1.) your barriers to trying it
2.) your impressions of the map
3.) whether you're interested in applying this within your team
4.) anything else.
</code></pre>
<i>Don't have access to an IPA file?</i> Email me at illahi@prodscape.net and I will send you one to try.<p>Thanks!
