I'm working to reinvent personal websites. My goal is to replace social media with personal sites + newsletters, which are more distributed, privacy-friendly, and calm. https://postcard.page The product seems simple, but there are so many opportunities for optimization. There's caching, CDNs, custom domain support, dynamically-generated open graph images, image optimizations, email sending, email reputations, analyti…

Beaker browser wanted to do this, and it was awesome

Sounds fascinating, what could possibly go wrong? “Your scientists were so preoccupied with whether or not they could, they didn't stop to think if they should.” —Dr. Ian Malcolm (Jurassic Park).

Kind of an uncharitable quote, considering I have essays and presentations going back 8 years (and more recently) where I question potential harmfulness to the environment. I also previously worked for 3yr at a nonprofit specifically aimed at improving the world/society with biotech, where we considered these questions carefully and deeply. In any case, blatant sarcasm is also out of the spirit of hackernew’s “ Be ki…

Responding to the first part of your comment, I’m glad to hear that!

Name suggestions welcome! I suck at naming - Peer Review was a working title intended to be somewhat tongue in cheek (similar to StackOverflow). But... because I suck at naming, it is, of course, a little on the nose. So far I haven't come up with anything better.

Unless 'peer review' elicits negative feelings in the target audience it seems like a pretty good name. It relates to the core concept, it's respectable and easily memorable. Seems like good branding but I'm no expert, nor am I the target audience. To toss a few names in the hat, off the top of my head: - openresearch - colab - openjournal - stud.io Probably collect a few ideas and run a small survey for the initial…

My concern is that "peer review" is a wide term, it would be kind of like calling a startup Web Browser or Network Engineering. Too much confusion.

I’m working on combining economics and information theory. Econ talks a lot about “informed markets”, but doesn’t measure that in Shannon’s bits.

That's interesting! I don't suppose you blog or have some other way that people can follow your progress on this at all? Best of luck with it.

breaking Eroom's law. in the last 50 years the costs and timeline of drug development (clinical trials) were in increase. A phenomenon first published in nature and described as Moore's law reverse. As of today it costs ar. $800Mio and it takes 12 years to bring a cancer therapeutic to the market.

I spent 8 years as a cancer scientist in drug discovery space, till I realised it doesn't make much sense to keep searching for more potential targets, if they will end up on a shelf for lack of clinical trials budget.

I am trying to solve this issue by platforming the infrastructure. Bringing web2.0 to clinical drug development.

I have been using a solo WhatsApp group as my "notes app" for years. Quite common with Android users. But when I needed a dedicated notes app to get a little more organised, I couldn't find anything satisfactory. The popular notes app are way too complicated for my purpose. The lesser knowns usually don't have a good UI/UX. And there's also the issue of privacy.

I needed a privacy respecting notes app which worked like whatsapp. So I built exactly that - https://play.google.com/store/apps/details?id=com.makenoteto...

Took inspiration from Signal and called it Note to Self.

Automatic camera calibration refinement/healing. SfM is a well developed area, and there are well understood methods for gathering correspondences like SIFT in order to calibrate cameras. However, it usually requires a separate calibration phase prior to doing whatever you want to do with that calibration. In my case, we’re using it to triangulate 3D objects from 2D object detections done in each of our calibrated ca…

Is this anything you're ready to share? I'm interested in something similar in the context of Drones.

I can at least share some research that has been useful for what I'm working on: https://arxiv.org/pdf/2104.08568.pdf

Face reidentification is the approach this paper uses to find corresponding views of the same person, but that's not necessary if you have the ability to match the objects in your scene otherwise. For example, doing 3D triangulation to geometrically verify random matches using RANSAC.

Not tiring at all, when it's not a trope. This forum contains a surprising number of posts of sometimes ridiculously blind US-praising that is rooted in simple ignorance of how things run elsewhere and in the US. Concerning taxes though, I'll have to (quasi) side with you. 1040EZ is as easy as it gets. One could of course argue that in that case, in which the IRS has the numbers already, why do you have to be forced…

> Not tiring at all, when it's not a trope. The greatest fallacy of the pseudo-intelligent is comparing different first world countries to each other without considering demographics. It's a fallacy you have committed, along with everyone else who says "America is backwards lol". That is why it is a trope. It has nothing to do with American exceptionalism and everything to do with a relatively poor understanding of h…

You should try to read and understand posts before you try to pull out your own "pseudo-intelligence". Nowhere have I written "America is backwards".

You're using 'how we arrived here' as a cheap excuse of an excuse to justify a status quo that is worse than it is in other places. That's the trope of American exceptionalism right there, to somehow find consolation in 3rd world conditions through repeated 'but we are god's own country, screw that even China has a higher life expectancy'. Really, the trope here is how the proud patriots of the richest, most powerful country in the world simultaneously feel superior to everyone, yet feel butthurt and threatened by essentially anything else on this planet that doesn't exactly act/think/look like they do.

> Sure we could have a German tax system for the simplest filers. We got to the 1040EZ because we believe in theory governments should stay out of our business.

That makes no sense whatsoever. As you write yourself, 1040EZ simply lets you confirm what the government already knows. The difference to the German system is that you still have to jump through hoops, roll over, and catch the ball when the government tells you to. I guess you also see the 'Obey the speed limit' signs in Texas as manifestation of supreme liberty, contrasted to the oppressive German 'no speed limit'.

Most other Western countries have much more powerful (= effective) checks and balances, as should have become exceedingly clear by the failure of the American system to keep an even openly criminal President and his attempted coup in check. That game is still not over. Most of Europe learnt that lesson by studying what went wrong in Germany 90 years ago.

But, I mean, you do you.

I always wanted to take a challenge in an old boring industry and build something completely new. Myself, my co-founder, and a couple of other guys have looked recently into a very very boring hiring industry and had decided to do something about it. That's how the idea of Careera.io (https://Careera.io) was born. We have just started this month and currently working on an MLP (minimum lovable product), will launch soon and let you guys know then :) Basically, we want to completely remove and automate the majority of a very mundane process of hiring on both sides of the market (job seekers and hiring managers). We want to finally introduce a bit of magic into this industry! Wish us luck!

Do file watchers registered in the main thread get called and then enqueue a message to a worker thread for processing? I am guessing you want to keep the code that handles file events on the watcher and on startup the same code used in two places. Guessing you scan multiple source directories of files recursively. Does C# have a thread safe queue object? You could create a pool of worker threads and the file watcher…

> Do file watchers registered in the main thread get called and then enqueue a message to a worker thread for processing? Yes, Producer Consumer pattern. Currently a single thread each, but that would be scalable later. For now I try to keep things simple. > Guessing you scan multiple source directories of files recursively.

You seem to be taking a practical approach and I like it.

You're working on something interesting.

Thank you for sharing!
