JAX is a high-performance numerical computing library with a NumPy-like API. While many PyTorch users have heard about JAX, there are not that many straightforward, easy-to-follow tutorials. This tutorial helps readers understand the basics of JAX by connecting its concepts to PyTorch building blocks. It explores the basics of the JAX ecosystem from the PyTorch user and guides users through how to train a simple neural network with JAX and PyTorch.
o1 is not a chat model - it's like a report generator: give it enough context, tell it what you want outputted, and it'll often nail the solution in one shot. People often approach chat models by starting with a simple question and some context, iterating back and forth until the desired output is achieved. o1 needs as much context as possible otherwise it will just take questions at face value and won't try to pull context from the user. The most effective way to use o1 is to treat o1 like a new hire, give it as much context as possible, and focus on explaining what you want the output to be.
Nvidia's Project Digits will be powered by DGX OS, a customized Ubuntu Linux 22.04 distro. The desktop combines Nvidia's Blackwell GPU with a 20-core Grace CPU built on the Arm architecture. It can develop up to 1 petaflop of AI performance at FP4 precision and support 200-billion-parameter large language models. Nvidia's partnership with MediaTek will likely lead to a new generation of AI-powered PCs with significantly enhanced capabilities.
Automattic has announced that it will restrict its contributions to the open source version of WordPress - it will now put in about 45 hours a week in total, down from nearly 4,000 a week. The company is aiming to match the estimated hourly contributions of WP Engine as a response to WP Engine's legal response after actions by WordPress co-creator Matt Mullenweg. While usually, having the community take the lead would be fine, Mullenweg has the final say over some very important parts of the WordPress community. While it is fair for Automattic to focus on for-profit projects, Mullenweg still holds all the keys to WordPress. A fork is possible, but it will require new community-driven infrastructure.

The Supreme Court seems likely to uphold the law that would ban TikTok in the US. A preliminary decision is expected within days. There remains some uncertainty on how the court will handle the case, especially with President-elect Donald Trump taking office a day after the deadline for the law to take effect. The court has the authority to temporarily block the law even if it ultimately rules against TikTok.
One of Elon Musk's lawyers has called on the California and Delaware attorneys general to force OpenAI to auction off a large ownership stake. Musk has previously launched lawsuits to attempt to stop OpenAI from restructuring to a for-profit company. He co-founded the startup with Sam Altman and nine others in 2015. OpenAI has no plans for an auction.
Blue Origin's New Glenn rocket launch at Cape Canaveral Space Force Station in Florida was called off this morning after hours of delays. As tall as a 32-story building, the rocket was set to launch on January 10, but the launch was postponed due to choppy seas in the Atlantic Ocean where the booster is supposed to land. New Glenn is designed to carry larger satellites and other payloads than other rockets in operation today. Its success could inject competition into the rocket business, which is currently dominated by one company - SpaceX.
Neuralink has implanted its brain-computer device into a third patient. The company has plans for up to 30 more implants this year.

Datadog analyzed AWS cloud cost data from hundreds of organizations [9] to understand the impact of technology choices, patterns of cloud resource usage, and participation in AWS discount programs. The findings reflect changing priorities of engineering teams, and suggest that organizations have further opportunities for cost optimization.
werk is a simplistic and easy-to-use portable build system and command runner. It solves several problems with `make` and `just`. Developers just have to parse a Werkfile containing recipes to werk and it will determine what the user wants to build, what the dependencies are, and run programs to rebuild any outdated build products in the right order. It uses a new language, but the language is able to express the kind of things developers really want to express in build scripts and fairly pleasant and readable.
This article looks at how modern programming languages are governed and explains how Swift's dictatorial structure is uniquely terrible. Swift was originally a passion project by Chris Lattner, the senior director of dev tooling at Apple. The language has evolved into a complicated mess - it now has 217 keywords. While Apple is unambiguously the dictator of Swift, its incentives put the company at odds with the open-source community. The company's updates to the language show how much it doesn't care about the community.
Meta CEO Mark Zuckerberg recently criticized Apple's lackluster innovation efforts and 'random rules' during an episode of the Joe Rogan Experience podcast. He noted that while the iPhone was great, it introduced a platform with a lot of arbitrary rules, and that the company hasn't invented anything great in a while. He also said that Apple's reasons for pushing back on letting other companies into its ecosystem are invalid - the security problems could be solved by building better security. Zuckerberg claims that Meta would double its profits if Apple stopped applying its random rules.
Fears about human labor being replaced by machines go back hundreds, if not thousands, of years. These fears continue today with the rapid progress of AI in several previously secure human domains. The amount of intelligence competing in the average person's labor market has increased by several orders of magnitude over the past few centuries, but this did not turn low-skilled laborers into a permanently unemployed underclass - in fact, their incomes increased a lot as they specialized and traded with skilled workers. Human-level AGIs will still face constraints, forcing them to trade with humans for other services, just like skilled humans do.

TikTok will argue its case before the Supreme Court today in a case that will decide whether the government can ban the platform if it doesn't sever ties with China. The US government wants to ban TikTok due to concerns about China's control over the app. TikTok says the ban violates its First Amendment right to free speech and that the US government's security concerns are too vague and hypothetical to justify an infringement of its rights. If TikTok is banned on January 19, people who don't already have the app on their devices will no longer be able to download it from Google or Apple app stores. The law also bars US internet hosting services and data-storage providers from supporting the app. There are workarounds, but they are limited.
xAI has released an iOS app for its Grok chatbot in the US. It can perform the same functions as the chatbot built into the X app. The company has been testing the app in a handful of countries since December. There is no word on when it might come to Android. xAI is also working on a dedicated website for Grok.
SpaceX plans to test Starship's payload deployment mechanism on its seventh test flight, which could be launching as soon as January 13. The upcoming flight test will launch a new generation ship with significant upgrades. In addition to testing the payload deployment mechanism, SpaceX plans to fly multiple reentry experiments geared towards ship catch and reuse, and launch and return the Super Heavy booster. Details about the upgrades on the new generation ship are available in the article.
Blue Origin is aiming to launch its first orbital rocket on Sunday. The launch was delayed due to rough seas in the Atlantic, where the company hopes to land its first stage booster on a ship. The rocket, New Glenn, will carry a prototype of Blue Ring, a US Defense Department funded spacecraft. The launch will mark Blue Origin's long-awaited entry into the orbital launch market and escalate the rivalry between Jeff Bezos and Elon Musk.
The industry pivot to serverless compute hasn't really happened despite an appealing value proposition. Friction against serverless is caused in part by fatigue from the last paradigm shift to microservices. Caution in the industry is reasonable as a shift to serverless will amplify the same type of challenges that were caused by microservices, many of which still aren't fully resolved. The main incentive for broad serverless is financial, not technical, it is unlikely for someone from the engineering department to sponsor the idea.
Miguel Carranza, founder of RevenueCat, writes a post every year looking back over the last twelve months. 2024 was a good year for RevenueCat, possibly its best since 2020. While the journey was a lot rockier than Carranza had imagined, it was clear the company succeeded in its goals. The post discusses the company's performance last year, the lessons it learned (on culture, hiring, company building, and scaling as a founder), and its plans for the future.
There's a growing underground market connecting job seekers to anonymous company insiders willing to help them get a foot in the door. While a referral is not a guarantee of a job offer, it can substantially improve the odds. There are several sites available that let people get in touch with verified employees of their target employer to discuss job referral opportunities. Many companies say that this is completely fair practice, but others, like Google and Goldman Sachs, disagree.
'Supporters of Chromium-Based Browsers' is an initiative started by the Linux Foundation that will provide funding and development support for industry leaders, academia, developers, and the broader open source community working on open Chromium projects. It will have an open governance model based on transparency, inclusivity, and community-driven development. Google has slowly loosened its control over the Chromium project over the years, allowing outside developers into its leadership, softening its stance on non-Google-derived features, and opening up its 'Goma' development scheme for Chromium.

References to an 'Apple Invites' app were first found in one of the iOS 18.2 betas. They were removed from the final version, but they are now back in iOS 18.3 beta 2. The app is likely designed to help users organize meetings and in-person events. It will essentially show a list of people invited to an event and who has already confirmed attendance. It is unclear whether Invites will be a standalone app or if Apple will integrate it with other parts of its system.
