Real-world experiments help, but they’re too slow and expensive to run at scale. So, we’re building simulations that let y

Making Libcurl Work in WebAssembly

29 Jul, 2025 TLDR: we explain how to make libcurl based applications work in webassembly without changes by tunneling all traffic over a websocket proxy. For a quick demo, check out https://github.com/r-wasm/ws-proxy Porting R to WebAssembly Webr is a port of the R language and its package ecosystem to WebAssembly. Many R packages rely on well-known C/C++ libraries to do the heavy lifting, and fortunately most of these libraries can be built with emscripten without too much trouble. However

Launch HN: Hyprnote (YC S25) – An open-source AI meeting notetaker

India overtakes China in smartphone exports to the U.S. as manufacturing jumps 240%, report shows

Workers assemble smartphones at Dixon Technologies' Padget Electronics Pvt factory in Uttar Pradesh, India, on Jan. 28, 2021. Bloomberg | Bloomberg | Getty Images India has overtaken China to become the top exporter of smartphones to the U.S., according to research firm Canalys, reflecting the shift in manufacturing supply chain away from Beijing amid tariff-fueled uncertainty. Smartphones assembled in India accounted for 44% of U.S. imports of those devices in the second quarter, a significant

Google breaks into the US top 4 for smartphone shipments, but don’t call it a comeback

Joe Maring / Android Authority TL;DR Google has become the fourth-largest smartphone shipper in the US, according to Q2 data. Shipment figures are being skewed by manufacturers racing to stockpile amidst volatile US tariff policies. India now supplies 44% of US-bound phones as brands shift production away from China due to higher trade risks. Google has edged into the top four US smartphone vendors, which might normally suggest a surge in consumer interest. But these aren’t normal times, and

I finally found a tablet that can easily replace my iPad and Kindle (and is affordably priced)

TCL Nxtpaper 11 Plus ZDNET's key takeaways The TCL Nxtpaper 11 Plus is available for $249. This tablet can switch from full color to an E Ink-like display with the press of a button, it has 256GB of storage, and an eye-catching matte display with 120Hz refresh rate. The Nxtpaper 11 Plus can get heavy when you use it one-handed and doesn't include a case or stylus, though you can buy them separately. $249 at Walmart I test a lot of tablets, and admittedly, the design aspirations of many of the

16colo.rs: ANSI/ASCII art archive

Sixteen Colors is an online archive for ANSI and ASCII artpacks. The artform was originally intended for display on computer textmode consoles. It gained popularity in the early nineties with the rise of dial-up Bulletin Board Systems (BBS). At one point artists started to group together and release their work in collections released monthly, these collection are called artpacks.

Post SMTP plugin flaw exposes 200K WordPress sites to hijacking attacks

More than 200,000 WordPress websites are using a vulnerable version of the Post SMTP plugin that allows hackers to take control of the administrator account.

CNET Survey: 64% of People Still Don't Want a Foldable Smartphone

Foldables have been a staple of the smartphone release cycle for years now, with products from companies like Samsung, Motorola and Google. Despite the refreshingly unique form factor in a sea of mobile uniformity, the vast majority of consumers still aren't sold. According to a CNET survey, 64% of respondents say they aren't willing or interested in buying a foldable smartphone in the next year, while just 13% say they are. An additional 20% aren't sure if they want a foldable and only 3% say

T-Mobile is crushing AT&T and Verizon, and these plans are the secret sauce

Edgar Cervantes / Android Authority TL;DR T-Mobile added 830,000 new postpaid subscribers in the second quarter of this year. The company’s consumer group president has revealed that over 60% of the new additions opt for two of its newest plans.

Trump’s order to make chatbots anti-woke is unconstitutional, senator says

The CEOs of every major artificial intelligence company received letters Wednesday urging them to fight Donald Trump's anti-woke AI order. Trump's executive order requires any AI company hoping to contract with the federal government to jump through two hoops to win funding. First, they must prove their AI systems are "truth-seeking"—with outputs based on "historical accuracy, scientific inquiry, and objectivity" or else acknowledge when facts are uncertain. Second, they must train AI models to

Manticore Search: Fast, efficient, drop-in replacement for Elasticsearch

Easy to use open source fast database for search Manticore Search is an easy-to-use, open-source, and fast database designed for search. It is a great alternative to Elasticsearch. Introduction ❗Read recent blog post about Manticore vs Elasticsearch❗ What distinguishes it from other solutions is: It's very fast and therefore more cost-efficient than alternatives, for example Manticore is: 182x faster than MySQL for small data (reproducible❗) 29x faster than Elasticsearch for log analytics (

Fun with gzip bombs and email clients

Gzip/Zip bombs have been a thing for decades. Lets create a 10MB gzip file which decompresses to 10GB: dd if =/dev/zero bs =1G count =10 | gzip > 10gb.gz This is called a Gzip bomb, because when it is decompressed, it blows up to a much larger size (~1000 larger). Add it your website document root and configure Nginx to serve it up as an image, with gzip Content-Encoding: location /10gb.png { default_type image/png; add_header Content-Encoding gzip; try_files /10gb.gz = 404 ; } An HTTP clien

Show HN: A word of the day that doesn't suck

I’ve long thought that the Word of the Day was a wasted genre. The goal should be to give you words you can use; to enrich your understanding of words you already know; or at least to use words to tell you something neat about the world. Instead, what you usually get is words that will never be used in conversation, held up as curios. Some examples from Dictionary.com’s daily email: thewless, balladmonger, vagility, contextomy. These words are... not useful. I’ve always thought I could do bett
