How we built a social network with No-Codehttps://news.ycombinator.com/item?id=35070143In the Fall of last year, we launched a social network for college students with No-Code.Here’s how we did it:Last summer (after having conversations with a few dozen college students), we stumbled across a very interesting insight:*80% of college students aren’t on Facebook anymore*.Sure, tools like Snapchat and Instagram exist that represent someone’s social graph, but there isn’t a central place for students to go get guidance from other peers. For students to even do simple transactions like exchanging textbooks, finding roommates, or buying sports tickets is messy.This gave us the idea that just maybe students were hungry for a new social network to fill the void Facebook left behind.Our goal was to create a digital community where students could discuss campus life, discover housing options, and buy/sell from other students.### Step 1: Build the PlatformTo make this happen, we started by setting up a (Circle)[https://circle.so/] community specifically for our first college, the UMar 8, 2023 3:27 PM

Launch HN: DAGWorks – ML platform for data science teamshttps://news.ycombinator.com/item?id=35056903Hey HN! We’re Stefan and Elijah, co-founders of DAGWorks (https:///www.dagworks.io). We’re on a mission to eliminate the insane inefficiency of building and maintaining ML pipelines in production.DAGWorks is based on Hamilton, an open-source project that we created and recently forked (https://github.com/dagworks-inc/hamilton). Hamilton is a set of high-level conventions for Python functions that can be automatically converted into working ETL pipelines. To that, we're adding a closed-source offering that goes a step further, plugging these functions into a wide array of production ML stacks.ML pipelines consist of computational steps (code + data) that produce a working statistical model that a business can use. A typical pipeline might be (1) pull raw data (Extract), (2) transform that data into inputs for the model (Transform), (3) define a statistical model (Transform), (4) use that statistical model to predict on another data set (Transform) and (5) push that data for downstream uMar 7, 2023 4:04 PM

Novel Prompt Injection Threats to Application-Integrated Large Language Modelshttps://arxiv.org/abs/2302.12173Title: More than you've asked for: A Comprehensive Analysis of Novel Prompt Injection Threats to Application-Integrated Large Language ModelsAbstract: We are currently witnessing dramatic advances in the capabilities of Large Language Models (LLMs). They are already being adopted in practice and integrated into many systems, including integrated development environments (IDEs) and search engines. The functionalities of current LLMs can be modulated via natural language prompts, while their exact internal functionality remains implicit and unassessable. This property, which makes them adaptable to even unseen tasks, might also make them susceptible to targeted adversarial prompting. Recently, several ways to misalign LLMs using Prompt Injection (PI) attacks have been introduced. In such attacks, an adversary can prompt the LLM to produce malicious content or override the original instructions and the employed filtering schemes. Recent work showed that these attacks are hard to mitigate,Feb 24, 2023 2:19 AM

Show HN: Web Digest – Collection of (daily) big stories on the webhttps://webdigest.pages.dev/I hate browsing news apps and news websites. It is a time-consuming, energy-draining, and information-overloading experience. There are endless articles to read if one is to read something. The journalism industry, including the UGC aspect of it, produces contents significantly more than what an ordinary human can process (or even decide which to process).However, I do find the fear of missing out a real problem which should be addressed, or even solved, and solving it with an illusion of not missing out is good enough. One has to be very selective in reading, otherwise one would be drown in the flood of information. I find it necessary to limit the size of readable contents and repel the creators/editors/platforms who tempt me to read more and more endlessly. Being long is not a problem for me, but having an unknown length is.Hence this project was brought forth onto this world.

Launch HN: IcePanel (YC W23) – Onboard engineers with explorable system designshttps://news.ycombinator.com/item?id=34338995Hey HN, Victor and Jacob here. We’re excited to show you what we’ve been building over the last couple of years! IcePanel (https://icepanel.io) helps architects and developers easily explain how their software works with interactive and explorable diagrams.Modern systems are complicated, and getting new developers up to speed and contributing fully is time-consuming and difficult. It costs the new developer's time, as well as the time of the senior first/second generation developers who help them constantly through their first 6 months. The resources people use to learn new systems are usually scattered across a maze of artefacts, like confluence pages or outdated draw.io diagrams, which are usually incomplete, with the ‘real’ understanding of the system being tribal knowledge in the team. As discussed in yesterday’s post https://news.ycombinator.com/item?id=34328069 “documentation only works up to a point” and we believe this is due to docs being disconnected from the code.

Show HN: Aliasing as Art – Moiré Patternshttp://www.nukacourt.com/moire.htmlI've found myself focusing on all the chaos going on in the world to an extent that's not healthy. So I decided to make some art that tries to find a little beauty in what otherwise seems chaotic.This is based on the concept of aliasing[1]. That's exactly what anti-aliasing is normally trying to address in computer graphics, but here aliasing is leveraged to generate interesting visuals. It took some doing to overpower the anti-aliasing that browsers insist on doing. If you look at the JS embedded in the HTML, you'll see that it's nothing more than ~4,000 straight lines being drawn from the center of the window to the edge of the circle that circumscribes the corners of the window. Those lines alternate between cyan and purple, all on a yellow background. The elaborate patterns are merely interactions between the jaggies[2] of adjacent lines. If you want to get more intuition for this, try downloading the source and increasing the increment size in the loop (i.e., the `milliradians += Nov 21, 2022 9:00 AM

Show HN: A crypto social trading platform that improves Etoro's copy-trade modelhttps://tordess.comHey HN,I was watching an interview of Caroline Ellison (CEO of Alameda Research) the other day and found it interesting that she never uses stoploss (no wonder shit happened). One of the most important skills for traders is how to set up stoploss and stick to it when stoploss is about to hit. I see that most crypto traders don't follow this principle.There is a huge demand for social trading (similar to Etoro) from crypto traders. Fact: 76.2% crypto traders surveyed say that they want to have social trading (copy-trade) features - Source: Statista (2021). There have been multiple attempts from various crypto start-ups (including the ones backed by major crypto exchanges such as Binance or Bybit) trying to build Etoro-equivalent for crypto.However, due to the volatile nature of crypto markets, most of the top traders on such platforms are pure gamblers, who may have luck once in a while. Most of the copiers there cannot obtain sustainable profits from copying the top traders. Users do nNov 15, 2022 10:07 AM

Vintage Tech Humor: Unknown Technology Definitionshttps://news.ycombinator.com/item?id=33153189While archiving an ancient USENET group, I came across this bit of crass humor from 2003.SEX/seks/ [Sun Users' Group & elsewhere] 1. Software EXchange. A technique invented by the blue-green algae hundreds of millions of years ago to speed up their evolution, which had been terribly slow up until then. Today, SEX parties are popular among hackers and others (of course, these are no longer limited to exchanges of genetic software). In general, SEX parties are a Good Thing, but unprotected SEX can propagate a virus. See also pubic directory.2. The mnemonic often used for Sign EXtend, a machine instruction found in the PDP-11 and many other architectures. The RCA 1802 chip used in the early Elf and SuperElf personal computers had a "SEt X register" SEX instruction, but this seems to have had little folkloric impact.DEC's engineers nearly got a PDP-11 assembler that used the "SEX" mnemonic out the door at one time, but (for once) marketing wasn't asleep and forced a change.
