Show HN: See the stock trades your representative is making https://bit.ly/2OrcZ14

Show HN: See the stock trades your representative is making Hey HN, I am the creator of senatestockwatcher.com and im finally happy to say that the same data that is filed from the House of Representatives is now live for everyone to watch, report against, and use. https://bit.ly/3rR0vNK When Senate Stock Watcher was released, the US was in the midst of an election year and after the COVID market crash the SEC had opened some investigations on 3 Senators for insider trading allegations. My interest in politics and finance lead me to build that website, but the number one question I always got was "where is the houses' data?" The House of Reps exclusively files their transactions reports in PDF forms that vary wildly in quality and format, so OCR was not a trustworthy and tenable solution. There is a supporting platform for the community to contribute to this dataset so that it can eventually be 100% complete. To date, I have transcribed over 690 transactions. There are literally hundreds of thousands more to go. If you would like to help on this front - you can also go to: https://bit.ly/3fIhNKB This data is available, totally open, in both JSON and CSV format so that people more savvy than me can uncover trends and patterns.

Show HN: I wrote an HN bot to suggest HTTPS url when people post HTTP URLs https://bit.ly/3fTS5mH

Show HN: I wrote an HN bot to suggest HTTPS url when people post HTTP URLs It's inspired by this comment I made: https://bit.ly/3cQjF25. I actually saw several comments with HTTP URL posted, and that was the only one I bothered to comment on. So I thought that this is something better suited for bots than human. I hacked this together over yesterday and today: https://bit.ly/3drHSuw. Basically it uses the Firebase API (https://bit.ly/3fIrmJE) to find comments with HTTP URLs in them, try the HTTPS version, compare the contents, post back a comment if the contents are more than 95% similar. The "95% similar" part was actually the first part I wrote in the code. At first I tried a few existing go packages implementing diff/lcs, but most of them was quite slow and does a lot of allocations when I'm comparing two randomly generated 10KiB blobs, so I wrote my own (https://bit.ly/31Zs2Cp), which is optimized for space (it does almost no allocations), and it's also faster because allocations are slow. (I know this is an unfair comparison that most of the existing implementations need to give you an output that can be used to reconstruct the two blobs back, so at least some of their allocations are required and unavoidable) I also wrote a bug that it would find the same HTTP url in every run and post the same comment over and over again. My apologize to dang or whoever dealt with it (or maybe the system is good enough that it blocked those repetitive comments automatically). In the end it successfully made 6 comments across ~4 hours (not including the repetitive ones). All of those comments are flagged (likely due to hn policy), https://bit.ly/3sPWxq3 is the only one that's still visible to other users at the time of writing, if you are curious. I just killed it completely from the request of dang. Although it only lived for a few hours, it's still a fun exercise. Maybe I'll convert it into a reddit bot next? Who knows.

Show HN: A decentralised VC firm using Bitclout? https://bit.ly/2PW2piS

Show HN: A decentralised VC firm using Bitclout? Experiments are fun. I recently came across Bitclout, and I love the underlying concept. It’s ballsy, will it work? — time will tell. I think Bitclout as a thesis is moving towards the right direction. Decentralised Social Media networks will be the next thing and allowing users to own their own social equity and monetise that is the future. Last year I started an experimental fund, Khoob (https://bit.ly/3wpN6Qn) The idea was to invest in and build interesting Indian companies (a Betaworks / Expa for India). Thus far we have made 4 investments, and are building 4 companies. At Khoob I’m the solo GP, no LPs — so plenty of room to experiment. Currently Bitclout is aiming at helping individuals productise themselves. Individuals are brands, so why not an actual brand? The VC (venture capital) space is also undergoing a metamorphosis (eg. Sahil Lavingia's recent distributed raise for Gumroad). With that said we setup : https://bit.ly/2R8KTIT Currently the revenue into Khoob comes in the form of: 1). Dividends from investments / companies we have built. (Revenue Sharing) 2). Carry from liquidation events. (M&A, Secondary Sales). At the end of Q2–2021 we will be using 10% of our proceeds to purchase Khoob coins on Bitclout. Purchasers of our coins will be invited into a mailing list where we will be opening up data regarding current / future investments and companies we are building. This experiment will be about understanding whether we can decentralise Khoob as a fund and bring on (micro)LPs in a radically different way. Would love your thoughts/feedback.
