The only time HN is this interested in Bitcoin is when there's a bubble (2017)

The only time Hacker News is this interested in Bitcoin is when there's a bubble forming Sun 30 July 2017 You might have got the impression that there are a lot of Bitcoin-related posts on Hacker News lately. With SegWit set to activate in the next few weeks, and Bitcoin Cash likely to fork off on the 1st of August, I took a look at Hacker News' relationship with Bitcoin over the past years. In this post I'm going to argue, based on historical trends of Bitcoin-related posts on Hacker News, t

A 37-year-old wanting to learn computer science

5 July 2025 Who am I? The title says it. I am a 37-year-old wanting to learn computer science. But who am I really? I am someone who has always wanted to build stuff. I am fascinated by the process of creating anything. And it gives me unbridled pure joy to have people use something I have built in a meaningful and useful way. I am not a complete beginner in computer science. I am still a somewhat-beginner. At least I know how to hack my way to build and host a minimalistic static blog like

Ready-made stem cell therapies for pets could be coming

Earlier this week, San Diego startup Gallant announced $18 million in funding to bring the first FDA-approved ready-to-use stem cell therapy to veterinary medicine. If it passes regulatory muster, it could create a whole new way to treat our fur babies. It’s still an experimental field, even though people have been researching stem cells for humans for decades. Seven-year-old Gallant’s first target is a painful mouth condition in cats called Feline Chronic Gingivostomatitis (FCGS), which Gallan

Air pollution may contribute to development of lung cancer in never-smokers

Now, a study published on July 2 in Nature has uncovered compelling genomic evidence that points to air pollution—and other environmental exposures—as a potential major factor behind this growing public health concern. The study was jointly led by researchers at the University of California San Diego and the National Cancer Institute (NCI), part of the National Institutes of Health (NIH). “We’re seeing this problematic trend that never-smokers are increasingly getting lung cancer, but we haven’

Rocket Scientists Hooked Up ChatGPT to the Controls of a Spaceship, and the Results Were Not What You Might Expect

AI Kirk Despite being stumped by simple children's games and uncontrollably hallucinating, AI models could perform surprisingly well when put in charge of navigating space inside a simulated spacecraft, researchers have found. As Live Science reports, a team of scientists from MIT and the Universidad Politécnica de Madrid, Spain, instructed OpenAI's blockbuster AI chatbot ChatGPT to "operate as an autonomous agent controlling a pursuit spacecraft." To their amazement, as detailed in a paper s

Mini NASes marry NVMe to Intel's efficient chip

I'm in the process of rebuilding my homelab from the ground up, moving from a 24U full-size 4-post rack to a mini rack. One of the most difficult devices to downsize (especially economically) is a NAS. But as my needs have changed, I'm bucking the trend of all datahoarders and I need less storage than the 120 TB (80 TB usable) I currently have. It turns out, when you stop running an entire YouTube channel in your home (I'm in a studio now), you don't need more than a few terabytes, so my new c

HP 15.6″ Touchscreen Laptop (16GB RAM, 256GB SSD) Is Over 40% Off, Now Cheap 4.8-Star Pick at Best Buy

Big Brother at the Border Is Searching for a ‘Hidden Language’ in People’s Text Messages

United States Customs and Border Protection (CBP) has a bad snooping habit, and it’s looking for a little help to get its fix. According to a report from Wired, the agency is currently asking tech companies to pitch it ideas for a digital forensics tool that would allow it to process and analyze data from seized phones and computers and potentially uncover “hidden” patterns. In a federal registry listing from June, CBP said it is seeking a tool that can scan text messages, pictures, videos, con

Forget Anker, This UGREEN USB-C Charger Block Is Going for Peanuts in Amazon’s Fourth of July Deal

Modern life is filled with all sorts of amazing bits of tech, and while they’re all really handy, they’re also all very power-hungry. It can make keeping everything charged a real hassle, especially if you’ve only got a few chargers, or you’re in a household with a bunch of people. Everyone wants to charge their stuff, but there are only so many chargers to go around. See at Amazon Of course, the simplest fix to this isn’t getting rid of those people, as much as it might be tempting, but to gr

Laid-off workers should use AI to manage their emotions, says Xbox exec

“These are really challenging times, and if you’re navigating a layoff or even quietly preparing for one, you’re not alone and you don’t have to go it alone. I know these types of tools engender strong feelings in people, but I’d be remiss in not trying to offer the best advice I can under the circumstances. I’ve been experimenting with ways to use LLM Al tools (like ChatGPT or Copilot) to help reduce the emotional and cognitive load that comes with job loss. Here are some prompt ideas and use

Internet and TV Bundle Prices Are Up This Year. How to Cut Back

If you've noticed your TV and internet bills going up recently, you're not alone. Internet and TV bundles increased for the first quarter of 2025, recent JD Power data shows. Though surprisingly, unbundled internet bills saw a slight decrease. Finding ways to cut back on monthly bills can feel nearly impossible, especially when there's a price increase every few months. But it's possible. Here's more on JD Power's findings and what CNET experts recommend to help lower your TV and internet bills

This is not a tattoo robot

I walked into Blackdot’s tattoo studio in Austin’s east side on a sweltering May afternoon. After shaking my sweat-soaked hand, founder and CEO Joel Pennington led me up into an office building and opened the door to a small, three-room space. Critics have unflatteringly compared the studio to a sterile hospital room — a comparison not entirely without merit. In a corner room, the machine I had come here to see loomed: a humming, fridge-sized device reminiscent of an old X-ray unit. Blackdot cal

Ted Cruz’s Bid to Reclaim Space Shuttle Discovery Could Cost $400 Million

At a time when money is too tight for NASA’s science exploration endeavors, Texas senators are willing to pour millions into a risky process to relocate the Space Shuttle to Houston under the so-called One Big Beautiful Bill. President Donald Trump’s tax and spending bill, which passed the Senate on Tuesday, includes a provision to move the Space Shuttle Discovery from the Smithsonian’s Air and Space Museum in Virginia to Space Center Houston. The Bring the Space Shuttle Home Act was added to t

Tariff Impacts Are Real: These 13 Companies Have Confirmed Price Hikes

Higher prices for a lot of popular products seem inevitable on our current trajectory. James Martin/CNET In many cases and for many products in the US, the biggest impacts of President Donald Trump's aggressive tariff plans haven't hit yet -- but they could soon, unless the 90-day pause on some rates is extended. Still, numerous companies have already hiked prices or said that they'll increase in the near-future -- including, most recently, a popular and CNET-approved brand of smart lights. Th

The EU Proposes New Rules to Govern the European Space Race

There are around 11,000 satellites orbiting Earth, and it is estimated that at least 50,000 more will be launched in the next decade. There are also exploration instruments, resupply vessels, and complexes like the International Space Station. But who regulates all this activity in space? In the absence of clear regulations, the European Union has proposed the Space Act, a set of measures that seeks to make the European space sector a cleaner, safer, and more competitive environment, both domest

This Is Why Tesla’s Robotaxi Launch Needed Human Babysitters

Whether due to consumer backlash or an aging EV lineup, or both, Tesla sales have again seen a global plunge, this time 13 percent last quarter compared to the previous year—proof that the electric automaker hasn’t yet turned around a dismal year that saw public opinion of controversial CEO Elon Musk plummet. It could mean Tesla faces a second straight year of falling sales. And yet: Tesla is still the world’s most valuable automaker by market capitalization, worth some $990 billion. At least s

Major reversal in ocean circulation detected in the Southern Ocean

Satellite data processing algorithms developed by ICM-CSIC have played a crucial role in detecting this significant shift in the Southern Hemisphere, which could accelerate the effects of climate change. Thanks to data obtained from Earth observation satellites, an international team of scientists has detected an unprecedented phenomenon for the first time: a reversal in the ocean circulation of the Southern Ocean. The study, led by the National Oceanographic Center (NOC, United Kingdom), was r

Congress passes budget to expand mass deportations, cut social services, and stall clean energy

The Republican-controlled US Congress has passed a budget bill that includes cuts to social programs like Medicaid and more funding for Immigrations and Customs Enforcement (ICE), alongside provisions that discourage wind and solar energy production. Passed after a marathon debate in both houses, it will allow President Donald Trump to realize policy goals he’s so far attempted to push through executive orders and Elon Musk’s Department of Government Efficiency (DOGE). Trump intends to sign the
