Musk Announces First Human Implant of Brain-Computer Interface Chip, Controlling Phones with Thought is Just the Beginning#

This article mainly reports on Musk's announcement of the first human implant of a brain-computer interface chip and introduces Neuralink's product Telepathy and brain-computer interface technology. The article points out that this technology aims to help those who have lost bodily control for various reasons, allowing them to control phones or computers merely by thinking, thus enabling control over almost any device. The article also discusses Neuralink's flexible electrode technology, the possibility of device lithium batteries and implant wires moving within the brain, and issues the company faces in animal experiments.

Brain-computer interfaces can help these special groups, but I doubt whether a "helper" for normal people will appear in this form.
Even if I look forward to mechanical ascension, I do not wish to have any foreign objects in my brain.

Replicating Parts of Train Stations in All Provincial Capitals Nationwide#

In this collaboration, Baidu's Wenxin Yiyan foundational model will be deeply integrated with Galaxy AI, adding advanced features such as intelligent summarization, advanced typesetting, and real-time call translation to the S24 series.

Wenxin Yiyan's understanding and generation capabilities are similar to Gemini Pro, enabling the upgraded Samsung Note Assistant to transcribe content into text in real-time, distinguish speakers, and support multilingual translation and meeting minutes generation, enhancing cross-language communication and office efficiency.

Additionally, the S24 series inherits the innovative feature "Circle to Search," pioneered by Google, allowing users to intuitively search text, images, or videos with simple gestures, quickly obtaining accurate results from Baidu search.

Regardless, multimodality is the most basic function; otherwise, it is of little significance.

A Bunch of Young Americans Living Off Their Parents' Money#

Yeah, duh
Parents providing financial backing for their adult kids is hardly a new or surprising concept, but the scale of that support jumps off the page:

The majority of under-30 Americans lack total financial independence from their parents. Just 16% of adults ages 18-24 are entirely off their parents’ payroll. That number goes up to 44% for those ages 25-29.

Household expenses, phone bills, and streaming subscriptions are the most common chip-ins. Despite the horror show that is rent and mortgage, only 17% of adults ages 18-34 get help making those payments.

That said, the number of young adults living with their parents has increased: 57% of American adults under age 25 share an address with a parent, up from 53% in 1993.

The “why” behind all of this isn’t hard to find. For starters, inflation has been extra painful for young Americans, and the housing market increasingly favors the old.

What are parents saying?
Fifty-nine percent of parents reported financially assisting their adult children over the past year — and many aren’t blinking much of an eye at it.

It isn’t just a one-way street, BTW: Parents giving help is far more common, but 33% of adults ages 18-34 say they’ve financially supported their parents in the past year. (Only 14% of parents acknowledged receiving help, though. Hm.)

Readers and commentators tell us that as soon as they reach adulthood, American parents kick their children out to live independently.

One Billion Row Challenge#

Your mission, should you decide to accept it, is deceptively simple: write a Java program for retrieving temperature measurement values from a text file and calculating the min, mean, and max temperature per weather station. There’s just one caveat: the file has 1,000,000,000 rows!

Hamburg;12.0
Bulawayo;8.9
Palembang;38.8
St. John's;15.2

The goal of the 1BRC challenge is to create the fastest implementation for this task, and while doing so, explore the benefits of modern Java and find out how far you can push this platform. So grab all your (virtual) threads, reach out to the Vector API and SIMD, optimize your GC, leverage AOT compilation, or pull any other trick you can think of.

China's Leading Edge in Chip Startup Financing Over the US is Greater Than Ever#

When it comes to venture capital for computer chips, the gap between the US and China has never been wider.
When it comes to venture capital for computer chips, the gap between the US and China has never been wider.

In 2023, the US’s share of global semiconductor startup funding was just 11%, versus 75% for China, according to a recent report from PitchBook, a market research firm. PitchBook defines semiconductor startups as companies working on chip design and manufacturing as well as production and equipment.

Prohibiting sales is not as good as cheap dumping; the talent and infrastructure for chip design are developing, and the barriers are getting lower.
However, strict checks are needed to determine whether there is real technology or just a shell to defraud money.

International Court Rules Israel May Be Committing Genocide in Gaza#

After more than three months of Israel’s merciless assault on Gaza, Friday’s judgment from the International Court of Justice (ICJ) has come as some vindication for the 2.3 million Palestinians trapped in the hell that the enclave has become. Fifteen out of 17 jurists, legal experts from around the world, found it plausible that Israel is committing genocide against Palestinians.

Of course, this is of no use; it has happened before, but it seems no Israelis have faced punishment, after all, there is a good son in America.

Military Leaders in the UK and Across Europe Warn That Peacetime May Be Coming to an End#

As Russia’s war in Ukraine grinds on and the prospect of a Trump presidency becomes more likely, military leaders in the UK and across Europe have been warning that peacetime may be coming to an end.
As Russia’s war in Ukraine grinds on and the prospect of a Trump presidency becomes more likely, military leaders in the UK and across Europe have been warning that peacetime may be coming to an end.

In his first speech as Defence Secretary, Grant Shapps echoed this sentiment, saying that we are moving from a “postwar” to a “prewar” world. And it’s not just the UK: Germany’s Defence Minister, Boris Pistorius, predicted that a Russian attack on a NATO country is only five to eight years away. With a dwindling army – Britain’s military is the smallest it’s been in 400 years – the threat feels more palpable than ever to some. The head of the British army, General Sir Patrick Sanders, said during a military conference Britain should train and equip a citizen’s army because years of poor recruitment have meant that the number of fully trained army personnel has dropped to record lows, leaving the UK vulnerable. Though he was not advocating for conscription, the idea of mass mobilization has set off alarm bells.

Downing Street and the Ministry of Defence (MoD) swiftly dismissed the claims made by Gen Sanders, insisting that there were no plans to reinstate national service. But for today’s newsletter, I spoke with Guardian security and defence editor Dan Sabbagh about the crisis in the military, and what it means for Britain’s security. But first, the headlines.

Logically speaking, anyone who can say that Russia will attack NATO countries is either foolish or malicious; since they can become Defence Secretary, it goes without saying.
How could Russia possibly have the strength to move westward? The Soviet Union couldn't do it, let alone now.
If NATO does not expand westward, how could the war between Russia and Ukraine happen? It is purely falling into America's trap.

New York Times Morning Report: Changing Tastes in Chinese Cinema#

Good morning. China was once a big moneymaker for Hollywood. Last year, no American movie broke the Top 10 at the Chinese box office.
Good morning. China was once a big moneymaker for Hollywood. Last year, no American movie broke the Top 10 at the Chinese box office.

“Barbenheimer” — the portmanteau given to the same-day release of “Barbie” and “Oppenheimer” last summer — was a genuine cultural phenomenon for much of the world. Cinemas were filled with outfits in various hues of pink. Social media frothed with opinions. And the films brought in a combined $2.3 billion globally.

The “Barbenheimer” story played out differently in China, though. Neither movie cracked the nation’s top 30 releases last year. In fact, as my colleagues Claire Fu, Brooks Barnes and Daisuke Wakabayashi have reported, it was a bad year for all of Hollywood at the Chinese box office, where no American movie broke the list of top 10 highest-grossing movies.

Barbie: A boring children's movie, with no resonance among Chinese audiences; perhaps only children's movies made in Japan have a market in China.
Oppenheimer: An American political film; how could one expect people from other countries to watch it?
Others (that's you, Marvel) are boring, politically correct, and have weak plots.

Going on a Voyage#

AI Summary#

This article mainly introduces the experience and related details of cruise travel. Compared to other types of travel, a cruise trip requires almost no planning or itinerary, and activities and meals are free, making it very suitable for traveling with parents or young children. The cruise model is that after paying for accommodation, other expenses are free, but there are also some paid items, such as drinks, activities, and restaurants. After boarding, passports are collected, and various expenses and activities are charged using a room card. Cash can be used on board, but it is in US dollars. Reservations and prices can be checked through the official website, and different types of rooms have different prices, with free activities available for children. When choosing a room, it is recommended to select a room in the middle of the lower deck to avoid seasickness. There are both paid and free restaurants on board, with the main free restaurants being the Main Dining Room and the Sail Away Restaurant; the Main Dining Room serves Western cuisine, has a strong sense of ceremony but slow service; the Sail Away Restaurant is a buffet, with quality comparable to that of resort hotels in scenic areas.

Excerpts#

Activities

• Simulated Skydiving: Flying in a wind tunnel, a first-time experience, quite fun. The free experience is a 1-minute course.
• Deck Surfing: Divided into two types, lying down to kneeling and standing, as different boards are used; it’s very thrilling. However, the queue area is too sunny, so be mindful of sun protection.
• Bumper Cars: Very fun; sometimes there are few people in line, so you can often check it out and hop on when it's less crowded.
• Archery: Personally, I also enjoy it. When there are fewer people later, you can play to your heart's content.
• Table Tennis: The company has it, so I'm not very interested.
• Basketball: Not very interested either.
• Motion Sensing Game Machines: Kids love it; when I played, there was a kid guiding me, I see that kid playing this every time I pass by, feeling like he might be an NPC.
• Children's Arcade: Not coin-operated; it directly uses the room card.
