It reports that UPI, especially QR-code payments, is widely used for small transactions, while cash remains significant. ### Source excerpt Photo by David Dvořáček on Unsplash Prior to 2019, the biggest pain in Nitesh Bansal's life was getting customers to pay their dues. Bansal runs a Kirana cum mobile recharge store at Surat in Gujarat. Customers would keep on buying things at his store over and above an existing credit line, inflating the dues. " The typical excuses would be- "Forgot cash at home", "Settle the current bill, will pay the dues later" , "Don't have change" etc. In June 2019, Bansal latched on to one of the UPI platforms and since then things have changed. Digital payments have made his life a lot easier, by making credit settlements fuss-free. His customers now scan the QR code or pay him via Paytm. That doesn't mean he has gone completely digital; 60% of the payments at his store still happen in cash- a reality that has also been reflected in OkCredit's data UPI and within that QR codes have been the heroes of this digital revolution. Be it the neighbourhood vegetable vendor or the street food hawker, it isn't uncommon to find QR codes pasted on their shops and carts. The sheer convenience of scanning a code rather than looking for change or navigating through multiple apps makes QR codes a clear favourite among small and micro businesses. In fact, 90% of online payments happening on OkCredit take place through UPI, giving it a significant lead over all other forms of payments. While convenience is the primary reason, it has also been seen that shops that accept digital payments have a better control on cashflows than those who don't. Three shops away from Bansal's store, Ajay Sirohi's "Beena recharge point" suffers regularly because of non-paying customers. Despite several customers requesting him to add digital payments at the store, Sirohi hasn't done it for fear of cyber frauds. Payments are always an issue at his store, forcing him to resort to borrowing from his friends. Interestingly, for shops accepting digital payments, smaller denomination transactions are mostly happen throu ## Pine Store Community Pricing & Online Retail Stores DevFeed: [Pine Store Community Pricing & Online Retail Stores]() Original publisher: [Read original article]() Published: 2020-12-02T00:00:00Z Content type: opinion Language: en Sources: [Community blog on PINE64]() Topics: [foss](), [Linux](), [Hardware](), [Support](), [Wiki]() Tags: [community](), [developers](), [foss](), [hardware](), [linux](), [pine-store](), [pine64](), [pinebook](), [product](), [retail](), [software](), [store](), [support]() ### AI overview PINE64 explains that new online retail stores planned for 2021 will operate alongside the existing Pine Store, whose community-oriented pricing and device sales will remain unchanged. The strategy is intended to serve general consumers while preserving the existing community-focused model and reducing pressure on support staff from software troubleshooting requests. ### Source excerpt In 2021 you'll see online retail Pine stores open in Europe, North America and possibly also worldwide at a later stage. Let me start by making one thing clear - the current Pine Store isn't going away and the pricing in the Pine Store will remain unchanged. You'll always be able to buy and pre-order your devices from pine64.com at a community-oriented price point. The retail stores will function alongside the Pine Store, not replace it, and offer a different customer experience. In this blog I'll explain the rationale behind this strategy. PINE64 is not a business First things first - PINE64 is a community, not a business, and the Pine Store's sole purpose is to serve this community by providing FOSS development-friendly hardware. Sales numbers and revenue are not, and never were, a driving force behind this project; making the next fun and often experimental device was and still is. Some devices, such as the original Pinebook, were even sold at a loss at times - simply because we knew people wanted one. Seriously. Victims of our own success Our strategy was always clear - work with developers to design a product, have partner projects and community developers work on the software and sell the device at a community-oriented price point. This approach has proven to be a great way forward for us, and one that, dare I say it, ultimately distinguished us from the other FOSS-vendors and manufacturers. That said, we're slowly falling victim to our own success. News of our devices have reached people outside of our target audience, and enthusiast-grade products now frequently end up in the hands of non-technical customers. I have just been looking at the incoming support tickets these past weeks, and the majority of incoming queries are by people who are not comfortable troubleshooting software problems, have little Linux experience, and do not understand the nature of our devices. In a nutshell, they are general tech-consumers unfamiliar with the intricacies of Linux, FO ## Setting Up AWS S3 Buckets + CloudFront CDN for your Assets DevFeed: [Setting Up AWS S3 Buckets + CloudFront CDN for your Assets]() Original publisher: [Read original article]() Author: andrew@nystudio107.com (Andrew Welch) Published: 2020-01-23T23:01:00Z Content type: tutorial Language: en Sources: [nystudio107 | Articles on modern web development.]() Topics: [Amazon S3](), [Amazon Web Services](), [Cloud](), [Content Management System](), [cloud-infrastructure](), [Caching](), [Website]() Tags: [assets](), [aws](), [aws-s3](), [cdn](), [cloud](), [cloud-storage](), [cloudfront](), [cms](), [convenient](), [distribution](), [here-s](), [how-to](), [inexpensive](), [insights](), [latency](), [like](), [right](), [s3](), [storage](), [store](), [using]() ### AI overview A tutorial on storing website and CMS assets in Amazon S3 and serving them through CloudFront.

Here's how to set it up right. ## Overcast 5.1 with Instant Search DevFeed: [Overcast 5.1 with Instant Search]() Original publisher: [Read original article]() Author: Marco Arment Published: 2019-01-28T18:14:38Z Content type: release Language: en Sources: [Marco.org]() Topics: [App](), [Caching](), [Users]() Tags: [app](), [cache](), [local](), [search](), [store](), [update](), [wi-fi]() ### AI overview Overcast 5.1 introduces Instant Search, combining a small local cache with an optimized search service to return relevant podcast results as users type, including after a single letter. The cache downloads weekly over Wi-Fi and is less than 5 MB. ### Source excerpt ▶ The first thing someone does in a podcast app is add some podcasts, and most active Overcast users add at least two new podcasts each month. Over 80% of podcasts are added to Overcast by searching, with the vast majority as searches for a specific podcast by name (rather than searching for generic keywords, such as "business"). Good search is a critical, differentiating feature of any podcast app. I'm not satisfied if the podcast you're looking for is somewhere in the middle of a long list -- I want it to be the first one, displayed quickly, after typing the fewest characters possible. I've been building toward this by analyzing years of popularity statistics and anonymous search data. Instant Search is the next step in Overcast's search evolution. It combines a small local cache with a highly optimized search service to give the most relevant results immediately as you type, even after only a single letter.1 It's a dramatic, delightful improvement to a critical, frequently used feature. This was a lot of fun to build, and I'm proud of it. See for yourself! Overcast is free on the App Store. If Instant Search isn't instant right after you update, the cache hasn't fully downloaded yet. It's downloaded weekly, only on Wi-Fi, and is less than 5 MB. ↩︎ ## DNSFS explores using open DNS resolver caches for temporary file storage DevFeed: [DNSFS explores using open DNS resolver caches for temporary file storage]() Original publisher: [Read original article]() Author: ben@benjojo.co.uk Published: 2018-01-12T16:23:33Z Content type: article Language: en Sources: [benjojo blog]() Topics: [Filesystems](), [Internet](), [DDoS](), [Server]() Tags: [ddos](), [dns](), [files](), [internet](), [payload](), [resolver](), [risk](), [store]() ### AI overview The article describes DNSFS, an experimental filesystem concept that stores data in caches belonging to open DNS resolvers. It contrasts this approach with PingFS and discusses cache persistence, redundancy, and the security risks of publicly reachable resolvers, including DDoS reflection. ### Source excerpt DNSFS.
