Chinese national accused of stealing AI secrets from Google facing new charges
A Chinese national who has been indicted for allegedly stealing AI secrets from Google is facing additional charges, federal prosecutors said.
The Department of Justice announced Tuesday that a grand jury indicted Linwei Ding, also known as Leon Ding, on seven counts of economic espionage and seven counts of theft of trade secrets. Ding, a 38-year-old software engineer who had lived in Newark, was previously indicted on four counts of theft of trade secrets last March after he allegedly stole 500 confidential files from Google.
He was hired by the company in 2019, prosecutors said.
According to the superseding indictment, Ding allegedly uploaded more than 1,000 files containing confidential company information into his personal Google Cloud account from May 2022 through May 2023.
Prosecutors said the trade secrets pertained to the company's hardware infrastructure and software platform that allows Google's supercomputing data center to train and serve large AI models.
"The trade secrets contain detailed information about the architecture and functionality of TPU chips and systems and GPU systems, the software that allowed the chips to communicate and execute tasks, and the software that orchestrated thousands of chips into a supercomputer capable of training and executing cutting-edge AI workloads. The trade secrets also pertain to Google's custom designed SmartNIC and related software," the indictment said.
During that time, Ding was offered the position of chief technology officer of a Chinese-based tech company. Between Oct. 2022 and Mar. 2023, Ding was in China seeking to raise capital for the company, the indictment said.
In May 2023, prosecutors said Ding had founded a second tech company in China focused on AI and machine learning and was acting as its CEO.
The indictment also alleges that he uploaded more files from Google in Dec. 2023, which the company detected. Prosecutors said Ding did not tell Google that he had previously uploaded 1,000 files or his affiliations with the Chinese-based companies.
Google uncovered the uploads after finding out that Ding had presented himself as CEO of one of the companies during an investor conference in Beijing, the indictment said.
The FBI executed a search warrant at his home in Jan. 2024 and Ding was arrested two months later.
According to prosecutors, Ding faces a maximum of 10 years in prison and up to a $250,000 fine for each trade secret count and 15 years in prison and a $5 million fine for each count of economic espionage.

South Dakota is on track to spend $2 billion on prisons in the next decade
SIOUX FALLS, S.D. -- Two years after approving a tough-on-crime sentencing law, South Dakota is scrambling to deal with the price tag for that legislation: Housing thousands of additional inmates could require up to $2 billion to build new prisons in the next decade. That's a lot of money for a state with one of the lowest populations in the U.S., but a consultant said it's needed to keep pace with an anticipated 34% surge of new inmates in the next decade as a result of South Dakota's tough criminal justice laws. And while officials are grumbling about the cost, they don't seem concerned with the laws that are driving the need even as national crime rates are dropping. 'Crime has been falling everywhere in the country, with historic drops in crime in the last year or two,' said Bob Libal, senior campaign strategist at the criminal justice nonprofit The Sentencing Project. 'It's a particularly unusual time to be investing $2 billion in prisons.' Some Democratic-led states have worked to close prisons and enact changes to lower inmate populations, but that's a tough sell in Republican-majority states such as South Dakota that believe in a tough-on-crime approach, even if that leads to more inmates. For now, state lawmakers have set aside a $600 million fund to replace the overcrowded 144-year-old South Dakota State Penitentiary in Sioux Falls, making it one of the most expensive taxpayer-funded projects in South Dakota history. But South Dakota will likely need more prisons. Phoenix-based Arrington Watkins Architects, which the state hired as a consultant, has said South Dakota will need 3,300 additional beds in coming years, bringing the cost to $2 billion. Driving up costs is the need for facilities with different security levels to accommodate the inmate population. Concerns about South Dakota's prisons first arose four years ago, when the state was flush with COVID-19 relief funds. Lawmakers wanted to replace the penitentiary, but they couldn't agree on where to put the prison and how big it should be. A task force of state lawmakers assembled by Republican Gov. Larry Rhoden is expected to decide that in a plan for prison facilities this July. Many lawmakers have questioned the proposed cost, but few have called for criminal justice changes that would make such a large prison unnecessary. 'One thing I'm trying to do as the chairman of this task force is keep us very focused on our mission,' said Lieutenant Gov. Tony Venhuizen. 'There are people who want to talk about policies in the prisons or the administration or the criminal justice system more broadly, and that would be a much larger project than the fairly narrow scope that we have.' South Dakota's incarceration rate of 370 per 100,000 people is an outlier in the Upper Midwest. Neighbors Minnesota and North Dakota have rates of under 250 per 100,000 people, according to the Sentencing Project, a criminal justice advocacy nonprofit. Nearly half of South Dakota's projected inmate population growth can be attributed to a law approved in 2023 that requires some violent offenders to serve the full-length of their sentences before parole, according to a report by Arrington Watkins. When South Dakota inmates are paroled, about 40% are ordered to return to prison, the majority of those due to technical violations such as failing a drug test or missing a meeting with a parole officer. Those returning inmates made up nearly half of prison admissions in 2024. Sioux Falls criminal justice attorney Ryan Kolbeck blamed the high number of parolees returning in part on the lack of services in prison for people with drug addictions. 'People are being sent to the penitentiary but there's no programs there for them. There's no way it's going to help them become better people,' he said. 'Essentially we're going to put them out there and house them for a little bit, leave them on parole and expect them to do well.' South Dakota also has the second-greatest disparity of Native Americans in its prisons. While Native Americans make up one-tenth of South Dakota's population, they make up 35% of those in state prisons, according to Prison Policy Initiative, a nonprofit public policy group. Though legislators in the state capital, Pierre, have been talking about prison overcrowding for years, they're reluctant to dial back on tough-on-crime laws. For example, it took repeated efforts over six years before South Dakota reduced a controlled substance ingestion law to a misdemeanor from a felony for the first offense, aligning with all other states. 'It was a huge, Herculean task to get ingestion to be a misdemeanor,' Kolbeck said. Former penitentiary warden Darin Young said the state needs to upgrade its prisons, but he also thinks it should spend up to $300 million on addiction and mental illness treatment. 'Until we fix the reasons why people come to prison and address that issue, the numbers are not going to stop,' he said. Without policy changes, the new prisons are sure to fill up, criminal justice experts agreed. 'We might be good for a few years, now that we've got more capacity, but in a couple years it'll be full again,' Kolbeck said. 'Under our policies, you're going to reach capacity again soon.'

Boulder Jewish Festival proceeds with enhanced security and focus on healing after attack
BOULDER, Colo. -- The group that was attacked last weekend in Boulder, Colorado, while calling for Hamas to release Israeli hostages will be a central focus of the Boulder Jewish Festival, which kicks off Sunday morning in the same location where the firebombing took place. Organizers of the festival, which is in its 30th year, said they have reimagined the cultural celebration to focus on community healing after a man who yelled 'Free Palestine' threw Molotov cocktails at Run for Their Lives demonstrators, according to law enforcement officials. Authorities have said 15 people and a dog were victims of the attack. Not all were physically injured, and some are considered victims for the legal case because they were in the area and could potentially have been hurt. Run for Their Lives, a global grassroots initiative with 230 chapters, started in October 2023 after Hamas militants from the Gaza Strip stormed into Israel, killing 1,200 people and taking 250 others hostage. Sunday's festival at the downtown Pearl Street pedestrian mall will center the group's cause — raising awareness of the 55 people believed to still be in captivity in Gaza. The Boulder chapter walks at the mall every weekend for 18 minutes, the numerical value of the Hebrew word 'chai,' which means 'life.' 'It is going to look very different this year. Run for Their Lives is going to be featured front and center,' said Miri Kornfeld, a Run for Their Lives organizer in Denver. 'The community is looking for a way to come together after an act of violence. People just want to be together, and they want to celebrate who they are.' A group representing families of the Israeli hostages plans to send at least one family to join the Boulder chapter Sunday as it resumes its weekly walks during the festival, Kornfeld said. Art, food and music are also planned. In response to the attack, the Boulder Police Department and the FBI are coordinating to provide increased security at the festival, local synagogues and the Boulder Jewish Community Center. Festival attendees can expect drones, SWAT elements and plainclothes officers in the crowd to increase safety and make people feel at ease, police Chief Stephen Redfearn said. 'Any would-be attacker, anybody that might come there to cause harm, I want them to see that we have a lot of people there, and hopefully that dissuades anyone from doing anything nefarious," Redfearn said Thursday. The victims of the attack include eight women and seven men, ranging in age from 25 to 88. One is a Holocaust survivor. Mohamed Sabry Soliman, 45, was charged Thursday in state court with 118 counts, including attempted murder, assault, illegal use of explosives and animal cruelty. He has also been charged with a hate crime in federal court and is jailed on a $10 million cash bond. Soliman, an Egyptian national who federal authorities say was living in the U.S. illegally, told police he was driven by a desire 'to kill all Zionist people," a reference to the movement to establish and sustain a Jewish state in Israel. Authorities said he expressed no remorse about the attack. U.S. immigration officials took Soliman's wife and five children, who also are Egyptian, into custody Tuesday. They have not been charged in the attack. A federal judge on Wednesday granted a request to block the deportation of Soliman's wife and children. Colorado Gov. Jared Polis, who is Jewish, has deemed the attack antisemitic, meaning it targeted Jewish people because of their identity or beliefs. Organizers have not confirmed whether all the demonstrators last Sunday were Jewish. The group is open to Jewish and non-Jewish participants. The violence in downtown Boulder unfolded against the backdrop of the Israel-Hamas war, which continues to inflame global tensions and has contributed to a spike in antisemitism in the U.S. It also came at the start of the holiday of Shavuot, which commemorates God giving the Torah to the Jewish people at Mount Sinai in Egypt. 'In the wake of the most violent antisemitic terrorist attack in Colorado history, we are reminded of the profound power of standing shoulder to shoulder,' Mindy Miller of Stop Antisemitism Colorado said at a community vigil Wednesday night. 'Let today be the beginning of a new chapter in Colorado — one where Jews no longer have to stand alone.'

I ignored this ChatGPT setting for months — now I use it every day
Like millions of others, I use ChatGPT daily. As a power user, I frequently use ChatGPT to summarize research, create images and I even use the bot to talk me down from a spiral of recently, I revisited an underused setting buried in the app that completely changes how the bot responds. It's so useful that I really wish I had taken advantage of it sooner. No, it's not a secret plugin or a pro-only feature. It's something that's been there the whole time: custom instructions. You've probably seen the button dozens of times but never bothered to click on it. It lives quietly in your settings menu under the heading: 'Customize ChatGPT.' This customizes the chatbot's behavior. Using customized GPTs dramatically improved how I interact with the AI by tailoring the chatbot to my specific of it as crafting perfect assistants for certain tasks. Instead of re-explaining your preferences every time, a custom GPT can be set up to understand your job, writing style, tone and even the kind of responses you want (short, long, complex, simple).Custom GPTs also support powerful tools and integrations. You can grant them access to a code interpreter, web browsing, image generation or even custom APIs and uploaded this feature turns ChatGPT into an even better assistant capable of analyzing data, generating visuals or referencing your documents without extra work on your part. Plus, you can set behavioral instructions so the GPTs always respond in your preferred tone or format, saving you time and improving consistency. For me, the hardest part about using a customized GPT is literally remembering to use it. Although it's just a click away, sometimes I'll dive into a prompt before I remember there's a better way to get the best you've built a custom GPT that works well, you can reuse it as often as you like or share it with others (a great asset for teams). Whether you're managing SEO, writing emails or brainstorming ideas, having a GPT fine-tuned to your process means faster, smarter output. It's a useful way to turn a general-purpose tool into a personal or professional super-assistant. If you're like me, you'll notice that when you finally start customizing GPTS, your experience with AI will shift entirely, and for the better. Your responses will feel clearer and far more personal. You won't get generic responses, but answers that fit your style and suggestions that are more engaging. Get instant access to breaking news, the hottest reviews, great deals and helpful tips. You can access this feature in just a few taps: Click your name (or the three dots in the bottom left) Tap Settings Select Custom Instructions You'll see two key fields: 'What would you like ChatGPT to know about you to provide better responses?'(Example: 'I'm a busy mom of three and want an empathetic, conversational tone that feels like I'm chatting with a friend.' 'How would you like ChatGPT to respond?'(Example: 'Use short paragraphs, avoid buzzwords, and give practical suggestions. Add a human tone, like you're texting a smart coworker.') Once you fill these out, that context is baked into every conversation. You don't have to reintroduce yourself or explain your tone again. ChatGPT just gets it. Custom instructions are convenient because they are like having a hat trick in your back pocket. Whatever issue you were having with ChatGPT earlier, such as answers feeling too generic or formal, this setting fixes turns the chatbot into something much closer to a real assistant and one that actually understands everything about you (well, as much as you feel comfortably telling it). It also means you'll spend less time rewriting responses and more time getting useful results. For example: When I asked it to write a note to the babysitter, it used formatting and tone I'd normally have to adjust. When I needed a list of birthday party locations in the area, it knew where I lived and pulled them up immediately. (This type of ultra personalization might not be for everyone, but I find it to be a time saver). And when I asked for snack ideas for the soccer team, the list actually sounded like something I'd submit (and easy enough for a busy mom to contribute); not something from a generic listicle generator. Best of all? It feels more personal without sacrificing quality responses. If you're using ChatGPT with memory enabled, custom instructions are the perfect complement. Memory helps the chatbot remember ongoing preferences and facts across conversations, while custom instructions give it a solid starting point for every new chat. Even if memory isn't your thing, these static instructions make ChatGPT far more efficient right out of the gate. This one setting changes how well ChatGPT can work for you. If you've been using the chatbot like a search engine or idea machine, custom instructions push it into a new category making it more like a personal AI assistant. You'll notice a difference when it starts answering like someone who knows your voice, your goals and how you think. Do you use custom GPTs? Let me know in the comments!
