What Is Complexity in Chess?

Pacto Visual May 2020 an interesting proposal was suggested. I provided some constructive criticism on research paper A Metric of Chess Complexity by FM David Peng, as well as constructive criticism on the codebase used to validate this experiment. For many months I have refrained from further comment, and although code has not progressed, two things have: 1. Public interest in "complexity" as determined by ACPL (yuck). 2. Lichess has a blogging platform where I can properly address deficien

Code Is Debt

“Tornike, what do you think of AI coding tools?” I like to answer this frequent question by way of an example. An example of two companies. It goes something like this: Imagine two very similar companies. Both companies generate similar revenue and produce a similar software product. The only difference between these companies is that Company A uses 1 million lines of code and Company B uses 100 thousand lines of code. Which company is better off? Clearly, the company with fewer lines of code

Touted As The Tesla-Killer, Lucid Scrambles to Stay On The NASDAQ

Beleaguered electric vehicle company Lucid Motors (LCID) has implemented a reverse stock split, consolidating shares to meet NASDAQ’s $1 minimum trading price and prevent delisting. As of Friday, Lucid’s share price was down over 96% from its all-time high of $64.86, reached in February 2021. While this move may protect the company from being removed from the exchange for now, it does little to address the underlying issues plaguing the struggling electric vehicle maker. Founded in 2014 by fo

J. Crew Is in Hot Water After Its “Vintage” Ad Turned Out to Be Faked Using AI

The American clothing brand J. Crew is under fire after it was revealed that the company used AI to guzzle up its own aesthetic and promote ads with seemingly fake models. The images, which were published to Instagram earlier this month, don't raise immediate alarm bells. Presumed human men are pictured embodying J. Crew's vintage Americana-prep aesthetic: vibing on boats, cycling past storefronts in muted colors, drawing and painting in their paint-splattered studio, and so on. But as style b

Verizon Finally Restores Service in Most Areas After Day-Long Outage

Verizon said thousands of people who were affected nationwide by a massive outage now have service back. If your Verizon-backed phone was out most of yesterday or even still down today, you weren’t alone. The company said the blackout was caused by a “software issue” but did not respond to a request to elaborate on what exactly that meant. Verizon officials assured customers that their engineers were actively engaged in diagnosing and resolving the service disruption. By early evening, the com

Google Investors Surprisingly Chill About Major Data Breach

The stock of Google’s parent company ended Friday’s trading session relatively unchanged, as investors digested news of a major data leak and broader market developments. Alphabet Inc. (GOOG)’s shares closed at $213.53, up slightly from the day’s prior end price, despite Google‘s global security alert advising its 2.5 billion Gmail users to update their information following a data breach involving one of its Salesforce databases. The company immediately issued a network-wide alert telling use

The M4 Mac Mini Offers the Best Value I've Seen From an Apple Product, and It's $54 Off for Labor Day

Labor Day deal: With concerns over tariffs and price increases, Labor Day offers greater discounts on a ton of items, including top tech like the Apple M4 Mac Mini. Right now you can pick one up for$545 at Amazon. This powerful computer already offers great value, so saving $54 is a bonus. But if you were planning on picking one up, we can't promise this deal will last beyond Labor Day, so we suggest buying sooner rather than later. I bought the M4 Mac Mini after reading CNET laptop expert Josh

These Hi-Fi Speakers Are Made out of Rocket Fuel Tanks

Momentum for space development is growing on a global scale. The rocket company SpaceX, led by CEO Elon Musk, has been carrying out numerous missions since putting its partially reusable Falcon 9 rocket into service. The company now boasts the highest launch frequency in the world, and this has helped boost the number of rocket launches worldwide to 254 last year. This is a dramatic increase of more than 20 percent compared to the previous year. In Japan, Honda has begun developing a reusable

Meta is struggling to rein in its AI chatbots

Meta is changing some of the rules governing its chatbots two weeks after a Reuters investigation revealed disturbing ways in which they could, potentially, interact with minors. Now the company has told TechCrunch that its chatbots are being trained not to engage in conversations with minors around self-harm, suicide, or disordered eating, and to avoid inappropriate romantic banter. These changes are interim measures, however, put in place while the company works on new permanent guidelines. T

PopSocket grips might be closely associated with smartphones, but they work surprisingly well with most e-readers. That’s because they let you prop up or securely hold any big-screen device with just one hand, making them a handy tool for those looking for a little more convenience. The fact that they come in an array of fun styles is just a plus.

Git Diagramming "The Weave"

We all know the current US President is one hell of an orator and often assures us that he has “the best words”: I went to an Ivy League school. I’m very highly educated. I know words. I have the best words. The man knows words. Says so right there. While some might view his non-sequitur ramblings as the nascent stages of dementia or an unfiltered ADHD brain launching into successive short (at times racist) bullet-point diatribes based on the last word or phrase he said like a cursed game of w

xAI sues an ex-employee for allegedly stealing trade secrets about Grok

xAI doesn't want its secret recipe for Grok to get out, and it's filing a lawsuit to make sure of that. In a lawsuit filed earlier this week, xAI claimed that former employee Xuechen Li stole the company's confidential info and trade secrets before joining the team at OpenAI. Elon Musk's artificial intelligence company also alleged that Li copied documents from an xAI company laptop to at least one of his personal devices. According to the suit, Li stole "cutting-edge AI technologies with featu

The space race is transforming Southern California's economy – again

In a giant Long Beach warehouse near where Boeing used to build the C-17 cargo jet, Vast is fabricating what could be the first commercial space station to circle Earth. Just up the road in El Segundo, Varda Space Industries has grown molecular crystals in microgravity with few impurities for pharmaceuticals that one day could be injected in cancer patients. And a little south in Seal Beach, a scrappy company called AstroForge aims to land a satellite on an asteroid just a football field wide

Bi-directional accountability: A leadership shift most organizations avoid

Most organizations enforce one-way accountability. The CBC framework flips that, making commitments mutual, visible, and enforceable. In CBC, ambiguity is a leadership failure, and credibility comes from delivering results — not titles. When things go wrong, it’s easy to point down the org chart, much harder to look up. In most organizations, accountability flows one way. Teams are held to deadlines, deliverables, and performance metrics, while leaders enjoy a looser standard — insulated by hi

Crypto Mining Stock Is Up 400% This Year As It Inks Nvidia Deal

Shares of Iren (IREN), an AI, cloud, and data center company, jumped nearly 15% on August 29 after announcing it had achieved “preferred partner” status with Nvidia.

In addition to the partnership news, Iren confirmed it has secured the purchase of up to $168 million worth of Nvidia GPUs, further fueling the company’s stock rally on the

No Amount of Money Can Make People Want to Work for Zuck

How much would you have to get paid to spend any amount of time with Mark Zuckerberg? For some of the folks who have joined Meta’s AI team, millions of dollars simply is not enough. According to a new report from the Financial Times, the Meta AI lab is such a mess (and presumably, Zuck is such a bad hang) that recent hires have threatened to quit within days of joining, and promotions have been handed out just to keep people from leaving. FT points to Shengjia Zhao, Meta’s “chief AI scientist,”

The fall of EV startup Fisker: A comprehensive timeline

Henrik Fisker once envisioned a burgeoning EV empire at the startup he named after himself, which was to be led by the Ocean SUV. But cracks started showing in that vision almost as soon as the Ocean hit the road in 2023. Fisker cut production targets multiple times, failed to meet sales goals and laid off staff. What’s more, its Ocean SUV was beset with software and mechanical issues, rendering it inoperable for some. Add troublesome brakes, sudden power loss and doors that wouldn’t open to th

How a legacy hardware company reinvented itself in the AI age

ZDNET's key takeaways Behind-the-scenes providers such as Cisco keep the cloud and internet alive. The 40-year-old company now positions itself as an AI infrastructure vendor. The challenge: proactively supporting millions, if not billions of devices worldwide. It's the nature of the market beast -- think about all the formerly booming tech providers that have disappeared

In addition to MongoDB's 44% rally, Pure Storage soared 33%, its second-sharpest gain ever, while Snowflake jumped 21%. Autodesk rose 8.4%. Since generative AI started taking off in

Cracks are forming in Meta’s partnership with Scale AI

It’s only been since June that Meta invested $14.3 billion in the data-labeling vendor Scale AI, bringing on CEO Alexandr Wang and several of the startup’s top executives to run Meta Superintelligence Labs (MSL). But the relationship between the two companies is already showing signs of fraying. At least one of the executives Wang brought over to help run MSL — Scale AI’s former Senior Vice President of GenAI Product and Operations, Ruben Mayer — has departed Meta after just two months with the

SSA Whistleblower’s Resignation Email Mysteriously Disappeared From Inboxes

On Friday, the Social Security Administration’s chief data officer, Chuck Borges, sent an email to agency staff claiming that he was forcibly removed from his position after filing a whistleblower complaint this week accusing the agency of mishandling sensitive agency data. Minutes after the email went out, it disappeared from employee inboxes, two SSA sources tell WIRED. “I am regretfully and involuntarily leaving my position at the Social Security Administration (SSA),” Borges wrote in the re

Alibaba shares jump 13% as AI drives cloud unit acceleration

Alibaba posted a better-than-expected bottom line in the June quarter fueled by accelerated sales at its cloud computing unit and a continued revival of its e-commerce business.

IFA 2025: What to expect from Samsung, Acer, Lenovo and more

IFA, Europe's answer to the CES, kicks off on September 5 in Berlin, Germany. The show likely won't be the biggest source of news in September — Apple's iPhone launch event is officially happening on September 9 — but it is usually home to its fair share of announcements. IFA 2024 featured new "AI PCs" from ASUS and Dell, including the first Inspiron laptop with Qualcomm's Snapdragon X Plus chip. There were plenty of more unusual ideas, too: Honor used the show to introduce a laptop with a detac
