I can search a database with 32 million records in less than 50 milliseconds. This speed is insane! There's no reason your search is slow. There's no reason you aren't using this library when building applications with a lot of data. Take a look at typesense |. It's an open-source search engine. It's crazy fast and easy to use. They are sponsoring this post. Here is their GitHub repository: You can use the library in Python, JavaScript, PHP, Ruby, Swift, and pretty much any other programming language out there. Here are some of the things you can do with Typesense: • Vector search over embeddings • Conversational search for RAG applications • Image similarity search • Voice search And it does all of this extremely fast. A few interesting notes about the library: • Optimized for developer happiness • Works out of the box for most use cases • Very intuitive API • Easy to deploy and scale Probably the best way to compare them is against ElasticSearch. The latter is much more complex to configure and run with a steep learning curve. Check their GitHub repository. They have examples, tutorials, and everything you need.

Why is Rust different than many/most programming languages? Alice Ryhl works on Google's Android Rust team, is a Rust language team advisor, and is a core maintainer of Tokio (the most widely-used async runtime in Rust) Timestamps: 00:00 Intro 04:09 Tokio: an overview 05:11 What Alice likes about Rust 12:48 Rust for TypeScript engineers 13:51 Moving from C++ to Rust 14:34 Memory safety 18:12 Garbage collection tradeoffs 21:46 Ownership, references, and borrowing 26:59 Unsafe in Rust 31:21 Crates and Cargo 35:55 Language design and RFCs 43:02 Building new features 46:30 Editions vs. versions 49:47 Getting paid to work on Rust 51:27 Contributing to Rust 53:03 Rust in the Linux kernel 55:45 AI use cases for Rust 1:01:35 Learning Rust 1:03:54 Book recommendation Brought to you by: • Antithesis – verify your system’s correctness without human review or traditional integration tests – and avoid bugs or outages. • Sentry – application monitoring software considered “not bad” by millions of developers Three things worth knowing about Rust: 1. Rust was designed to turn implicit failures into compile errors. Where other languages allow you to forget something, Rust makes an omission into a compilation error for things like null checks, uninitialized variables, or error propagation with the ‘?’ character. If you mess something up, it’s almost certain your program will not compile. If it does, at the very least you should see a lint warning. 2. Refactoring in Rust is safe and easy, thanks to the compiler. Alice: “I change a return type or struct field, then just fix the compiler errors until the compiler stops shouting. And then once I’ve done that, I’ve updated every place I need to update.” Rust’s focus on correctness makes refactoring it more straightforward than dynamically-typed languages and Java-style typed ones are to refactor. 3. “Editions” allow Rust to make breaking changes without ‘breaking’ anyone’s code. Rust editions (2015, 2018, 2021, 2024) can be mixed freely across crates. A library on the 2021 edition works seamlessly with a binary on the 2024 edition. This is how Rust evolves syntax (like adding async/await as keywords) without forcing an ecosystem-wide migration. Thanks a lot, Alice for this great discussion! And for your work on Rust.

We've spent years building LlamaParse into the most accurate document parser for production AI. Along the way, we learned a lot about what fast, lightweight parsing actually looks like under the hood. Today, we're open-sourcing a light-weight core of that tech as LiteParse 🦙 It's a CLI + TS-native library for layout-aware text parsing from PDFs, Office docs, and images. Local, zero Python dependencies, and built specifically for agents and LLM pipelines. Think of it as our way of giving the community a solid starting point for document parsing: npm i -g @llamaindex/liteparse lit parse anything.pdf - preserves spatial layout (columns, tables, alignment) - built-in local OCR, or bring your own server - screenshots for multimodal LLMs - handles PDFs, office docs, images Blog: Repo:

The ancient Library of Alexandria was one of the greatest human achievements in antiquity. It was a vast collection of knowledge from countless and varied sources and contained tens or possibly even hundreds of thousands of scrolls. For this reason, the destruction of the library has been a subject of keen interest by many lovers of knowledge. It is often regarded as a great tragedy. But who actually burned the Library of Alexandria?... Firstly, let us establish an understanding of what exactly the Library of Alexandria really was. It was part of a large center of learning in Egypt in the city of Alexandria, called the Mouseion. It was built during the Ptolemaic period of Egypt. This was a time during which a Greek dynasty ruled over the country (Hellenistic Era). The library may have been built during the reign of Ptolemy II Philadelphus in mid-3rd Century BC. It quickly acquired many scrolls from all sorts of sources. The Ptolemaic kings of Egypt supported it directly, due to the ancient Greek love of knowledge. The Library of Alexandria grew to enormous proportions. At its height, it allegedly held anywhere between forty thousand to four hundred thousand scrolls. It was perhaps the greatest center of learning in the ancient world. Nonetheless, the library is no longer in existence but was famously burned. The question that remains is who was responsible for this. Numerous dramatic events took place during the reign of Julius Caesar. Therefore, it should be no surprise that he had a hand in the burning of Library of Alexandria. At one point during his war against Ptolemy XIII, the Greek forces surrounded him in Alexandria, both by land and by sea. To escape, Caesar set fire to the enemy fleet in the harbor of the city. This strategy worked, but the fire also spread to the city itself, causing the Library of Alexandria to burn down too. According to Plutarch, a Greek historian from 1st Century AD: "Caesar was forced to repel the danger by using fire, which spread from the dockyards and destroyed the Great Library" Thus, it appears straight-forward enough that Julius Caesar burned down the Library of Alexandria. This occurred in 48 BC. However, things are not quite that simple. Some scholars believe that there is evidence the Library of Alexandria still existed even after Caesar allegedly unintentionally set it on fire. Strabo, in the later 1st Century BC, visited Alexandria. In his writings, he describes a visit to the Mouseion. According to some scholars, this is evidence that the library, which was part of the Mouseion, still existed. Other scholars note that Strabo never actually mentions the existence of the library in his day. In fact, his words apparently imply that it was no longer even a thing. Other scholars also try to refute this by pointing to the fact that Mark Antony allegedly gifted two hundred thousand scrolls to Cleopatra. This was after Caesar had burned Library of Alexandria. The logic goes that this must mean that library still actually existed. Otherwise, where would Cleopatra house all those scrolls? In fact, some experts believe this gift was likely to replenish the library’s collection after many of scrolls had been burned in 48 BC. However, this argument ignores the fact that there was a ‘daughter library’ elsewhere in Alexandria. This was called the Serapeum. It was actually a temple, but it was also used as an overflow for the main Library of Alexandria. Therefore, when Mark Antony gifted so many scrolls to Cleopatra, they could have been placed in Serapeum. This also potentially explains away another argument used in favor of Library of Alexandria still existing after Caesar’s time. A scholar named Didymus Chalcenterus lived in late 1st Century BC in Alexandria. He was a very prolific writer, allegedly producing thousands of works. Some scholars argue that he must have had access to library’s resources to be able to do so. 🎥© scenesofthepast (IG) #archaeohistories

Releasing Three-Roads (MIT License) It's the road library i built for my open world game, it contains an authoring library with a lane-aware graph structure, a threejs mesh renderer and a SVG renderer Most roads are modeled after german road topology, however it is quite easy to change it to any system you want. At its core, roads are defined as a collection of (curved) edges with nodes representing either extension points or junctions. You can split and merge lanes at any point on a road. Markings follow some logic, but might require adjustments depending on your use case. Highway ramps require some conscious effort to connect cleanly with inner city roads. The junction logic can be a bit messy depending on what edges flow in or out, i didn't go through all thousands of combinations but just fix them with codex as i build more roads in the city. It does not contain any props, except for a few in the demo app. Props are placeholders in the actual library, so you can place whatever you want for trees or street islands or highway signs. There is a documentation on how to author roads in the bottom of the readme Have fun guys, you can build quite sophisticated and complex road networks with it. There are limitations, after about 8 edges on a junction the topology can become very messy DEMO: Link to repo in first reply

Impact After Term | 15 : TVA's Tamil Digital Library — Bringing Tamil's Civilisational Knowledge to the Digital Age Established by Kalaignar in 2001 to enable the Tamil language to thrive in the Internet era and promote Tamil learning across the world, the Tamil Virtual Academy has spearheaded several pioneering digital initiatives. Among its most significant has been the Tamil Digital Library—created to preserve centuries of Tamil literature, manuscripts, archival records and cultural resources in digital form, while making them freely accessible to students, researchers and Tamil communities worldwide. Following the formation of the DMK Government in 2021, the Tamil Digital Library underwent a significant transformation. As Minister for Finance and Human Resources Management, Dr. PTR allocated ₹96.65 lakh in the 2022–23 Budget to accelerate the digitisation of rare books, manuscripts and archival collections. After assuming charge as Minister for Information Technology and Digital Services, he oversaw the next phase of its expansion, broadening both its scale and public accessibility. Today, the Tamil Digital Library hosts over one lakh rare books, manuscripts, journals and historical records. Nearly 19.89 lakh pages have been digitised, including over eight lakh palm-leaf manuscript pages, thousands of rare photographs and hundreds of hours of archival audio-visual material—creating one of the largest digital knowledge repositories dedicated to an Indian language. The initiative also placed a strong emphasis on accessibility. With an allocation of ₹1 crore for the Inclusive Digital Library, access was expanded for persons with visual impairments. During Dr. PTR's tenure as Minister for Information Technology and Digital Services, 12.85 lakh pages were converted using OCR technology, while 1.30 lakh pages were made available in accessible formats such as DOC, EPUB, DAISY and Braille-compatible editions. The initiative was further expanded through a series of dedicated digital knowledge platforms, including Tamilar Thagaval Attruppadai, the Digital Cultural Atlas and Kalaignar Karuvoolam. During this period, the complete digitised works of 38 eminent Tamil scholars, literary figures and leaders were also made publicly accessible, alongside thematic digital collections preserving Tamil Nadu's literary, political, social and cultural history. The impact has been substantial. Website visits increased from 1.25 crore in 2021 to over 17.25 crore by 2026, with more than 13.27 crore visits recorded during Dr. PTR's tenure, reflecting the growing global use of these digital resources. The Tamil Digital Library has transformed centuries of Tamil knowledge into a living digital resource for future generations.

C Language is to be learnt by running experiments on Bare-metal (just the CPU) and without the OS noise! I added more lectures to the C Language course under the "Bitwise Operators" and the video (a snippet from the last lecture listed above) shows the level to which the course is hands-on. I pretty much prove all the claims I make about the concepts by experiments! Lectures I added include - + What are bitwise operations and the types + Shift Operations - Left, Logical and Arithmetic Right + The Bitwise NOT operation + Understanding using printf + Understanding the Assembly View + Exploring the Shift operations + Assembly view of Shift operation I have been recording this course for over a year now, 91 Lectures (almost all with hands on experiments) and we are far from concluding it. I'll continue to add more... If learning by experimenting (and reasoning from first principles) is your thing, you will love this course. This is included as part of the library access and you can check the current table on contents here:

Anders Hejlsberg (Anders Hejlsberg) is a living legend: he created Turbo Pascal, Delphi, C# and TypeScript (and today TypeScript is the most-used programming language, globally, as per GitHub.) Timestamps: 00:00 Intro 02:48 How Anders got into programming 05:40 Building his first compiler 07:44 Turbo Pascal 12:25 Delphi 14:53 Joining Microsoft 19:41 Building C# 29:11 Async/await 34:01 The rise of JavaScript 37:52 Building TypeScript 42:58 How the TypeScript compiler works 48:30 JavaScript’s strengths and weaknesses 52:18 How Anders uses AI 56:03 What language features work well with AI 1:02:49 How software craftsmanship is changing 1:07:49 Performance and efficiency 1:09:29 Anders’ tool stack 1:11:30 A 30-year career at Microsoft 1:13:40 Book recommendation Brought to you by: Antithesis – verify your system’s correctness without human review or traditional integration tests – and avoid bugs or outages. WorkOS – Everything you need to make your app enterprise ready. turbopuffer – a vector and full-text search engine built on object storage. It’s fast, cheap, and extremely scalable. Four things that stood out to me: 1. “10x better for 1/10th of the price” is a proven winner. This is what Turbo Pascal did: it sold for $49.95 when competing compilers cost $500, and it was faster and more interactive than competitors’ products. Conveniently, the low price tag also killed off piracy 2. C# might have not existed without a famous court case. Microsoft originally hired Anders to architect its Java tools (Visual J++), but the Sun versus Microsoft lawsuit (1997-2001) meant Microsoft could not build on top of Java, as the company that owned Java’s IP (Sun) sued MS for alleged unauthorized changes to the Java language. Microsoft realized it had to build a new language that combined VB’s productivity with C++’s power. This led to C# and .NET. 3. TypeScript exists because Anders refused to build Script# for the Outlook .com team. Microsoft’s Outlook .com team asked Anders’ C# team to productize “ScriptSharp,” a language to cross-compile C# to JavaScript. Anders and the C# team pushed back, suggesting that a better approach was to fix JavaScript. Anders felt strongly that to be attractive to the best-of-breed developers in the JavaScript ecosystem, you want people to write JavaScript, and not another language like C#. 4. Designing a programming language is a 10-year play. As Anders puts it: “Version one is great, but has all sorts of issues. You’ve got to do version two, but it’s not until version three that it really starts to be great. Then you’ve got to convince people to adopt it.”

Anders Hejlsberg (Anders Hejlsberg) is a living legend: he created Turbo Pascal, Delphi, C# and TypeScript (and today TypeScript is the most-used programming language, globally, as per GitHub.) Timestamps: 00:00 Intro 02:48 How Anders got into programming 05:40 Building his first compiler 07:44 Turbo Pascal 12:25 Delphi 14:53 Joining Microsoft 19:41 Building C# 29:11 Async/await 34:01 The rise of JavaScript 37:52 Building TypeScript 42:58 How the TypeScript compiler works 48:30 JavaScript’s strengths and weaknesses 52:18 How Anders uses AI 56:03 What language features work well with AI 1:02:49 How software craftsmanship is changing 1:07:49 Performance and efficiency 1:09:29 Anders’ tool stack 1:11:30 A 30-year career at Microsoft 1:13:40 Book recommendation Brought to you by: Antithesis – verify your system’s correctness without human review or traditional integration tests – and avoid bugs or outages. WorkOS – Everything you need to make your app enterprise ready. turbopuffer – a vector and full-text search engine built on object storage. It’s fast, cheap, and extremely scalable. Four things that stood out to me: 1. “10x better for 1/10th of the price” is a proven winner. This is what Turbo Pascal did: it sold for $49.95 when competing compilers cost $500, and it was faster and more interactive than competitors’ products. Conveniently, the low price tag also killed off piracy 2. C# might have not existed without a famous court case. Microsoft originally hired Anders to architect its Java tools (Visual J++), but the Sun versus Microsoft lawsuit (1997-2001) meant Microsoft could not build on top of Java, as the company that owned Java’s IP (Sun) sued MS for alleged unauthorized changes to the Java language. Microsoft realized it had to build a new language that combined VB’s productivity with C++’s power. This led to C# and .NET. 3.

This is an actual hardware capture of our WIP #GTA 3 port to the Sega #Dreamcast. SUBSTANTIAL framerate gainz have come from converting the model geometry from triangle lists to triangle strips as well as from utilizing KallistiOS's "Direct Rendering" PVR API for fast polygon submission via the SH4 CPU's "Store Queues." Oh... plus we enabled LTO, and it seriously jumped like another 3-5fps. Funnily enough, there's still PLENTY of room for optimization... Every vertex you see was being transformed by the PS2's vector unit coprocessor, while these transforms are being done in plain C++ on the DC's SH4 CPU... These are being accelerated via the SH4's SIMD and fast-math instructions at this very moment. Yes, we got clipping bugs, but we've been too excited trying to push polygons and frames-per-second to bother fixing that shit just yet. Oh, and yes, this is now running on a 16MB stock Dreamcast. #gamedev #retrogaming #indiegamedev

THE MISSING CANTON LIBRARY FOOTAGE 🗣🚨 On February 7th, 2022, Louis Jutras from Canton’s IT Division emailed Trooper Dunne (Norfolk County MSP) surveillance footage from the Canton Public Library, per MSP’s request. Because of the town’s camera system setup, the footage was shared via a download link rather than direct files. Dunne then forwarded that same link to lead investigator Trooper Michael Proctor. A follow up email, obtained by @Marbury_v_Mad through a FOIA request, shows that Proctor sought help from Norfolk County Forensic Video Technician Colleen Crawford. But why would Proctor need assistance if the footage could have been easily downloaded and preserved in its raw form, with original metadata? Data that was never provided to Karen Read’s defense team. Then there’s Brian Tully, the officer chosen to testify about this footage. A curious choice since Dunne received the original link and Proctor led the investigation, both would’ve been far more relevant witnesses. As Proctor’s supervisor, Tully would likely have known about the missing footage from the Canton Library. Did he also communicate with Crawford? The original file sent by Jutras was a full one-hour segment (12:00 a.m.–1:00 a.m.), yet the version later used in evidence has missing roughly two minutes from 12:37 a.m. to 12:39 a.m. And now, this newly uncovered correspondence shows Proctor personally thanked Crawford for her help with this very footage.

Got something totally different, but exceptionally badass today to share! Here is a bunch of direct hardware captures of the (F)ixed (F)unction and (F)ast (F)ourier (T)ransform (T)esting audio visualization demos, running on my Sega Dreamcast! This incredible piece of science, engineering, art, and music started off as a crazy idea to port a bunch of GPU-based, Shadertoy audiovisual demos to the Sega Dreamcast, to play with combined digital signal processing and rendering on legacy fixed-function hardware. As you can see from the video, the FFFFTT repo includes a wide array of different demos, each providing different kinds of visualizations, each featuring different types of signal transformations and analyses, with many of them also being interactive, all done in real-time! Not only that, but you ALSO can freaking pause the playback and analyze the signals in real-time... crazy! The final resulting FFFFTT demos are an epic full-stack conglomeration of Ray's raylib, providing the backing infrastructure and graphics framework, which sits atop our GLdc driver for rendering, using David Reid's miniaudio library for sound playback, with its FFT and vector algebra accelerated for the SH4 CPU using my SH4ZAM math library... all ontop of KallistiOS, running on the Sega Dreamcast! Congratulations to meisei4 for the fantastic accomplishments, and a heart-felt thanks from me for bringing everything together to make this happen! You just laid the framework for some epic audio-based gameplay mechanics and other crazy science experiments in the future for whole community!

RUMOR | John Linneman said he heard from a couple of sources that Microsoft was very much going to continue disc support before the Xbox “reset” He heard “Microsoft was actually very much going to continue disc support, not because they value disc retail sales but because they wanted to ensure that all your Xbox games were still be playable on new Xboxes.” He mentioned that Xbox “could offer maybe like an external drive or basically some means. And I think that might all tie into this disc to digital stuff as well.” Also speculated that he sees a “future where Microsoft supports physical games going forward for users that want to take their library with them while Sony just completely cuts people off.” via: Digital Foundry

We wanted to show the performance and the insane power of the Static Hermes native FFI. But we don't yet support the all language features needed to compile React Native (soon though!), so we improvised. We imported the bindings for DearImGui (a popular C++ imperative game UI library that renders meshes), and Sokol (an amazing lightweight 3D backend in C) and wrote a small demo. "Imperative UI" means that the entire UI and the state of the screen is recreated on every frame, which suits our purposes to demonstrate SH very well. The demo runs 100% compiled native code. JavaScript runs in every frame and recreates the entire state of the screen. It is portable to all platforms, though the screen layout is not optimized for phone. We wrote the demo in C++ and in JS, to compare, and they both ran with the same performance. In the attached videos you can see the demo running at the stable screen refresh rate - 120Hz on my Mac, 60Hz on a old Moto G5 phone. It includes some widgets, an n-body simulation of planets, a playable game demo, etc.

Day 1 Unified Intelligence is happy to share updates on our new project. Work has begun on construction of #ArivuKendra Library Building in Alolli village in Chittapur taluk. Located in the Kalaburagi district (formerly Gulbarga district) in the Indian state of Karnataka, it is situated approximately 50 km from Kalaburagi city, the administrative headquarters of the district. Typically the entire material required for construction of this 853 sqft Library using #Ui Panels would have moved in a single 31 feet long truck. But, considering the narrow panchayat roads, we opted to move in 2 separate mini trucks. Local contractors employed by the Government department have prepared the concrete base. Our team was supported by locals in unloading the Ui panels and accessories. Today, the markings as per plan will be completed on the floor. Upon the markings we shall then anchor bolt runners on to the floor. Once that's completed, we become ready to vertically mount the panels as walls of the structure. I shall update on this very exciting project continuously. We will complete the entire building within 15 days with a team of six. The Government of Karnataka plans to have such modern knowledge centres in every panchayat of the state. E Mail: paul@ui.ltd Ph: +91 9886339775
