Ask HN: What's the best way to handle internal tech support?
3 by underyx | 3 comments on Hacker News.
My company has around 1000 CS reps and 200 engineers. The CS reps very often need to ask the engineers questions, report bugs heard about from customers, etc. Us engineers also get bug reports about the internal tools we've developed for CS. Currently, all this is handled via a simple Slack channel. This is actually great, since there's no bureaucratic cost to getting in touch, unlike with a proper ticketing system, and having actual public conversations is the fastest way to resolve issues. But of course, we started seeing inefficiencies in other aspects. The same questions keep being asked over and over again. There's an FAQ linked in the channel topic and it's automatically posted in the channel every 12 hours, but it's still not enough, we still get tons of questions that could be self-solved without engineers' intervention. So, that made me curious, how are other companies handling this? Could we somehow maybe auto-respond to Slack messages with the correct answer with some bot, or just come up with something that actually makes people check the FAQs before posting? Or is there some way better solution to replace all this?

Lemurs can smell weakness in each other

Lemurs can smell weakness in each other
Some people watch the competition carefully for the slightest signs of weakness. Lemurs, on the other hand, just give them a sniff. These primates from Madagascar can tell that a fellow lemur is weaker just by the natural scents they leave behind, finds a study on ring-tailed lemurs. The study reveals that getting hurt dampens a lemur's natural aroma, and that males act more aggressively toward scents that smell ''off.''

Simple logic for nanofluidic computing simulated
Invigorating the idea of computers based on fluids instead of silicon, researchers have shown how computational logic operations could be performed in a liquid medium by simulating the trapping of ions (charged atoms) in graphene (a sheet of carbon atoms) floating in saline solution. The scheme might also be used in applications such as water filtration, energy storage or sensor technology.

Computing power used to track the spread of cancer
Researchers have developed a new computational method that increases the ability to track the spread of cancer cells from one part of the body to another. This migration of cells can lead to metastatic disease, which causes about 90 percent of cancer deaths from solid tumors -- masses of cells that grow in organs such as the breast, prostate or colon. Understanding the drivers of metastasis could lead to new treatments aimed at blocking the process of cancer spreading through the body.

Mars valleys traced back to precipitation
The valley networks of Mars bear a strong resemblance to those found in arid landscapes on Earth. Researchers have been able to demonstrate this using the branching angles of river valley confluences. Based on these observations, they infer that Mars once had a primeval climate in which sporadic heavy precipitation eroded valleys.

New top story on Hacker News: Launch HN: Brex (YC W17) – Corporate Credit Card for Startups
Launch HN: Brex (YC W17) – Corporate Credit Card for Startups
153 by hdubugras | 95 comments on Hacker News.
Hi HN – We are Henrique and Pedro of Brex ( https://brex.com/ ). We've built a corporate credit card for startups that has high limits, an instant online application and no personal guarantees. Pedro and I built our first payments business in Brazil, Pagar.me, when we were teenagers. We came to the U.S. to attend Stanford. We joined YC W17 and realized quickly – even with a seed round in the millions – that we could not get a corporate credit card. We are Brazilian, young, and do not have U.S. credit. Even if we did have credit – we know that personally guaranteeing a credit card makes no sense for a business (more on that later). In Brazil, we raised $300K initially (when we were 16) from an investor that was willing to take a chance on us. In Brazil, even though there are 200 million people, there is very little venture capital financing and limited startup infrastructure (accelerators, resources, technical talent, executives experienced with high growth). We knew that $300K was all we were getting, so we had to find a business that could be cash flow positive quickly. It was easier to do that accepting payments online (which naturally generates cash), but it was an operational challenge for sure. We were able to grow quickly in Brazil because we hit the market at the right time, as ecommerce was transitioning to online payments and because we, better than any of the foreign competitors, understood the nuance of Brazil. Specifically on that point, in Brazil the consumer has the option to pay for any card transaction in installments, and that requires a cash outflow for the merchant. Pagar.me figured out how to productize that best to the online market there. When we got to the U.S., we assumed that the payments system here would be significantly more mature and sophisticated than it was in Brazil, however that was not the case. Particularly on the issuing side (banks extending credit cards), there has been very little innovation or using technology to innovate on features. That is how Brex was born. Over the past year we’ve been incubating and improving and just launched with an online self-signup that lets you get access to a virtual card in minutes. We waited to launch until we had this feature, as we know how much of a pain it is to go through the back and forth of online and paper-based applications. Brex underwrites by connecting directly with your bank account, which means we can offer higher limits than other cards, often 10x-20x more. From a software perspective, we rebuilt all of the payments tech from scratch, which we learned how to do in our last business. Even then, to build Brex it was still grueling having to deal with the obscure regulations surrounding Know Your Customer (KYC), heavy oversight from banking partners, and complexities associated with interacting directly with Visa. In doing so, we built awesome features like instant virtual cards issued to you and your team and we solved something this time that has been bugging us forever – the fact that you can never tell what a credit card charge is on your statement! We changed the data to give you the actual merchant / vendor and a link to the website. When we did this, we also realized we could do something really unique with receipts – because we know the actual vendor / merchant, we can match any receipt sent to us via SMS or email to your transaction immediately. No need to save receipts or deal with other integrations that have a huge delay between matching a receipt to a transaction, we do it in real time. Interestingly, from a technical standpoint, we did all this in Elixir. We thought it would be a good choice (and so far we are happy with our decision) because of the distributed nature of the systems that we built and we could rely on the Erlang VM to provide that infrastructure out-of-the-box. Our domain knowledge from Pagar.me allowed us to anticipate the system boundaries and therefore we could build our backend as a distributed system from day one. Another unusual feature about the Brex launch is that we are launching relatively late in our history and with a pretty significant amount of capital from our Series B. We launched the business at YC, but based on our background with Pagar.me and that we were focused on payments again, we raised a ~$7M seed round in Spring 2017. That round was led by Ribbit Capital – which we liked given our connection to Micky there and their expertise in Fintech. YC Continuity led our Series B. In both rounds, for us, it’s all about the relationship with the partner and firm, and we have been huge beneficiaries of the YC ecosystem. On a personal note, for us the non-personal guarantee aspect of our product is most salient. As I mentioned, we are foreign entrepreneurs who don’t have access to banking products in the U.S. It was demoralizing to come to the U.S. after being successful in Brazil and not be able to get a card – especially given how much activity, particularly online, requires a credit card. Personal guarantees mean an entrepreneur who has already taken a ton of risk has to further put their personal financials on the line, which even if the company pays on time, can hurt his or her credit. One aspect of the product that we’d love HN feedback on is the signup flow. We gathered great feedback from our beta, and we waited to launch until we had an instant signup product. In financial services, signup flows have meaningfully more constraints than do many consumer signup flows – particularly compared to those with freemium models. For example, we need to collect business information to comply with regulations around anti-money laundering and Know Your Customer standards, as well as ensure the customer’s ability to pay and set up autopay. These constraints mean not only a longer signup flow, but also one that integrates many third party vendors to do compliance, fraud and credit checks. The more integrations and data to handle, the more edge cases we need to be able to support seamlessly. It took a ton of engineering effort to get here, plus a lot of time enhancing our compliance processes and credit framework. In light of those constraints, we’re specifically looking for user feedback on whether or not the flow feels logical, intuitive and simple – and if there are adjustments to the order, text or design that could improve the UI. But we're interested to hear any of your ideas and experiences and discuss the Fintech space generally too. Thanks for taking the time to read this, we’re really happy to be posting here :) Henrique and Pedro

Nanomaterials could mean more algae outbreaks for wetlands, waterways
The last 10 years have seen a surge in the use of tiny substances called nanomaterials in agrochemicals like pesticides and fungicides. The idea is to provide more disease protection and better yields for crops, while decreasing the amount of toxins sprayed on agricultural fields. But when combined with nutrient runoff from fertilized cropland and manure-filled pastures, these 'nanopesticides' could also mean more toxic algae outbreaks for nearby streams, lakes and wetlands, researchers report.
