Tesla has revealed cheaper versions of its Model Y and Model 3. The new Model Y will cost $40,000, and the Model 3 will sell for $37,000. They have the same basic body shapes as the existing models, but have cloth interiors, fewer speakers, and less soundproofing. The cheaper Model Y has dual headlights rather than a continuous illuminated bar. Both vehicles can travel 320 miles between charges, slightly less than the costlier versions.
Science Corp., a Californian company, has created an engineered protein that could help blind people see. The protein, opsin, creates electrical currents when hit with light. Opsins usually need a powerful light source to generate a current, but Science's scientists were able to create opsins that generate an electrical current when exposed to regular indoor lighting. Science is currently building several things, including a device to restore vision and a chip that plugs into the brain using living neurons instead of wires - the new protein could help with both pursuits.

It's been almost 10 years since Prettier was released. This post tells the story of its birth and how technological innovation made an underlying source of tension - spaces versus tabs - no longer a thing. Prettier solved formatting, one of the most controversial engineering topics, in the span of just a few years. It is now rare to see a mainstream programming language that does not have a formatter that's widely adopted by its community.
Developers using a lenient policy with JSON Schema may prefer backward compatibility over full compatibility. Full compatibility doesn't allow developers to evolve sum types. The most common way to evolve a sum type is by adding a new variant, which is a backward-compatible change, but now a fully compatible one.
OpenAI is making a play to be the Windows of AI. While Apple's strategy of integrating hardware and software was immensely profitable, it left the door open for a competing platform to emerge. Microsoft's DOS operating system put IBM in a dominant role and secured Microsoft's position. OpenAI is trying to make ChatGPT the operating system of the future. It has the users, and now it is trying to attract developers.
Qualcomm is acquiring Arduino, an Italian company known mainly for its open source ecosystem of microcontrollers and software. Arduino will retain its independent brand, tools, and mission. The acquisition still needs to be approved by regulators and go through other customary closing conditions. While Arduino is committed to open-source hardware and software, there are concerns that the acquisition will mean that its ecosystem will eventually be locked down.

Eli Lilly's weight loss pill, orforglipron, can help people reduce their body weight by as much as a fifth. The drug targets the same GLP-1 receptors as weight loss injections such as Mounjaro and Wegovy. While the weight loss seen in people taking the tablet is not as stark as that seen in those taking injectable forms of the drug, the tablet is significantly more accessible and convenient. Eli Lilly expects substantial demand when the new pill is launched.
SpaceX's Starbase, a massive rocket development site and the home of Starship, started as little more than an impossible stretch of empty land along the South Texas coast. The degree of difficulty of transforming the site did not deter Elon Musk, so the company tackled its issues one by one. This article looks at how the company transformed the land into Starbase and the challenges that it overcame along the way.

85% of software engineers are using AI coding tools at work, but things like tokens aren't exactly cheap, so companies need to know how to measure whether or not they are worth the money. This article looks at how some tech companies measure AI impact to uncover insights on how to get started in this tricky field. Solid foundations matter. Have an experimental mindset when measuring AI impact.
R's central package manager, CRAN, builds each package before publication, testing against a variety of R versions and operating systems. Even if a package passes tests against the full matrix of R versions and platforms, CRAN still reruns the tests for all of the packages that depend on that package. This means some packages can be blocked until dependent packages are upgraded. This approach, which clearly puts a burden on package developers, results in an excellent workflow for R's central user base, who want to spend as much time as possible on the details of data analysis, not stuck in transitive dependency hell.
Jack Ma is now back on Alibaba's campuses and is more directly involved than he's been in half a decade. He had resigned as chairman in 2019 and retreated from the public eye after a speech he made in 2020. The company has been run by two of Ma's longest-serving lieutenants, Joe Tsai and Eddie Wu, since 2023. Signs of Ma's influence can be seen in the company's pivot to artificial intelligence and its declaration of war on e-commerce foes JD and Meituan.

UTF-8 was designed to represent millions of characters from different languages and scripts and still be backward compatible with ASCII. Every ASCII-encoded file is a valid UTF-8 file, and every UTF-8 encoded file that only has ASCII characters is a valid ASCII file. This post gets into how UTF-8 works. A link to a playground for visualizing and playing around with UTF-8 encoding is available in the post.
Postgres18 adds asynchronous I/O, which means faster reads for many use cases. This is a part of a bigger series of performance improvements planned. Asynchronous I/O allows workers to optimize idle time and improve system throughput by batching reads. It provides a more predictable and better-performing method for batching operations at the database level. Writes will continue to be synchronous as this is needed for ACID compliance.
14 governments representing three parties have taken turns at governing Nepal since 2008, when the country adopted a new constitution after abolishing its monarchy. After recent protests, the country's citizens used a virtual poll on Discord to elect its new leader. A Gen Z group called Hami Nepal ran a channel where a debate on the country's future was livestreamed. After hours of debate, participants selected former Supreme Court Chief Justice Sushila Karki to lead Nepal.
Eliezer Yudkowsky, the founder of the Machine Intelligence Research Institute (MIRI), a Berkeley-based nonprofit that studies risks from advanced artificial intelligence, believes that building powerful AI systems is a terrible idea that will end in disaster. He recently released a book co-written with MIRI's president aimed at stopping the development of AI. The book claims that everyone on Earth will die if any company or group anywhere on the planet builds an artificial superintelligence using anything remotely like current techniques. While some may see Yudkowsky as an extremist or a crank, he is a central figure in modern AI history, and his influence on the industry is undeniable.

Shipments from Samsung surged in the US in the second quarter while Apple's market share declined. Apple remains on top of the US smartphone market, but it is experiencing turbulence for the first time in well over a decade. Samsung's Galaxy and Z phone lineup has a massive span of devices that stretches from $650 up to $2,400, targeting customers at every single price point. Apple may release a folding phone next year - trying out new form factors offers Apple the opportunity to sell devices at higher prices.
Microsoft and OpenAI have reached a deal to extend their partnership. The agreement could ease OpenAI's path toward changes into a for-profit corporation. The companies have not disclosed the terms of the new contract but said that the current agreement was nonbinding. The agreement is a tentative win for OpenAI, which needed Microsoft's approval for its non-profit plan before it could be formally shared with state regulators. OpenAI told its venture-capital investors it would complete the restructure by the end of the year or risk losing out on $19 billion in funding.
A newly engineered protein therapy called RcoM-HBD-CCC has been shown to cling to carbon monoxide and expel the poison via the kidneys within minutes when given intravenously to mice. The protein quickly sponges up the toxin without binding to nitric oxide, a gas molecule that plays a key role in relaxing blood vessels. The protein was shown to cling to carbon monoxide in human blood in test tubes. It is unknown how the treatment will work in human bodies until it is tested, but human trials are still likely to be a few years away.
There are still many issues, such as battery life, reliability, and safety, that need to be solved before humanoid robots can scale. However, before that, it is important to consider whether it is worth the trouble to make a bipedal robot. We already have reliable, efficient, and cost-effective robots, just without legs. Safe and reliable humanoid robots have the potential to revolutionize the market at some point in the future, but it might not be worth the effort.

Evals are still a new practice for many product teams. A/B testing is no longer sufficient for AI product optimization because it's expensive to create variants. AI eliminates this constraint - it is now possible to have unlimited variants that automatically update periodically based on real-user feedback. The companies that evolve to think in evals will build products that improve faster than their competitors can run in a single A/B test.
The two standard approaches for counting the unique values in a large array of mostly-unique uint64s are to insert into a hash table and return the number of entries, or to sort the array, then count positions that differ from their predecessor. Sorting is typically faster than hash tables in a well-tuned implementation. This problem and its variants are the inner loop of some of the world's biggest CPU workloads. This article takes a look at why sorting wins, when one should choose hash tables versus a sort, and why it matters.
The even equity vesting schedule is quickly becoming a thing of the past. Many companies are now shifting to front-loaded vesting. This shift is a philosophical pivot toward a more dynamic, performance-driven compensation strategy. Top performing employees stand to benefit, while others will have more uncertainty of compensation in subsequent years.

It's possible to beat the best sort implementations with domain-specific knowledge, careful benchmarking, and an understanding of CPU micro-architectures. However, assumptions will become invalid and mistakes may creep in silently. Good sort implementations can be surprisingly fast even without prior domain knowledge. Developers should think twice about replacing high-quality sort implementations with something home-grown.
Automation is a tool, not a goal. We should never automate something for the sake of it. Automation is great for self-documenting, and it can help fight human error, but it should be wielded with purpose. It shouldn't be the default regardless of its effectiveness at being fit for any particular purpose.
TikTok is primed to disrupt Google. New research shows that there is a closing gap between Google and TikTok's search engines, especially among Gen Z. Many people are turning to TikTok while searching for specific categories like fashion and beauty advice, cooking, entertainment, and DIY. If Google continues down its current path, we could be headed into a fragmented search world where ChatGPT handles complex queries, TikTok serves users who want audio-visual results, and Google plays the middle while hanging on to its market share.
Oracle recently revealed in its fiscal first-quarter report that remaining performance obligations more than tripled from three months ago to $455 billion. The company has even more multibillion-dollar deals in the pipeline that could take that number past half a trillion.
