The hardest problem in operational weather prediction is not merely generating a plausible future. It is keeping that prediction anchored to a fast-changing atmosphere while preserving both global coherence and the local detail people actually experience. WeatherNext 3 attacks those requirements together by changing the model’s data contract: it learns from live observations, refreshes hourly, and emits several kinds of forecast from one shared system.

Quick facts

• Difficulty: MEDIUM
• Problem: String Compression
• Topics: Two Pointers, String

Problem gist

The input is an array of characters. It must be compressed in place by replacing each maximal run of equal characters with the character followed by the run length—except that a run of length one keeps only the character. A count with multiple digits is written one digit at a time. For example, a, a, b, c, c, c becomes the meaningful prefix a, 2, b, c, 3, so the method returns 5.

Astronomy’s familiar gallery of dazzling images can create the impression that the sky is thoroughly mapped. It is not. Even with thousands of visible-light telescopes and major observatories working from radio waves to gamma rays, large parts of the cosmos remain inaccessible, poorly surveyed or detectable only through signals other than light. The important question is no longer simply how far astronomers can see, but what kinds of information their instruments are still built to miss.

TBPN surfaced NVIDIA’s agreement to acquire Hugging Face in its September 3 post, “Why NVIDIA Bought HuggingFace.” The original announcement is NVIDIA’s “NVIDIA to Acquire Hugging Face”, and the deal terms are documented in NVIDIA’s SEC filing.

The headline is a nearly \$13 billion acquisition. The deeper story is that the leading supplier of AI accelerators is buying the place where much of the open-model ecosystem discovers, compares, modifies, and distributes its software. NVIDIA is not merely adding another product. It is moving closer to the point where developers decide what to run, which tools to use, and eventually which hardware to buy.

Bond investors are sending governments an uncomfortable message: borrowing is becoming more expensive for reasons that will not disappear with a single policy announcement. Long-term yields have climbed across rich countries, reflecting a mix of renewed inflation fears, heavy corporate borrowing and deep concern about public debt. The article argues that official efforts may calm markets briefly, but governments have few painless ways to restore confidence.

China presses the US for answers after a man dies hours after entering ICE custody (r/news)

• freedfg: Yeaaaah. It’s gonna get really messy when other countries start questioning….and sanctioning the US.
• ElectronicMoo: I thought Japanese internment camps were bad learning about them growing up. It’s boggling my mind we are back there again. Regressive.
• soulless___ape: China calling the US out on human rights… we are lost as a country.

Pennsylvania police officer charged in fatal shooting of student who went to wrong house. “At the time these two fatal shots were fired, Mr. Pysher had his hands up” (r/news)

• SlinkyMalinky20: This is horrendous. That poor kid and his family.
• Erion7: The fact that this POS cop got caught on camera blatantly lying about what was captured on his own bodycam is absolutely unsurprising.
• statslady23: I know a handful of drunk people who have gone to the wrong house. I know two who went in and slept. One didn’t find out til morning, and the people who owned the house that he had never met before made him breakfast. None of the people I know got shot. One did get arrested.

People over 30, what’s something you DON’T regret doing in your 20s? (r/AskReddit)

• VagabondAlbertan: Partying. Sounds stupid but enjoy hanging out with your friends before everyone has kids and responsibilities
• ducklady92: Traveling before I was too tied down to relationships/pets/jobs to do so on a whim. I used to spend every last dime on one-way tickets and just… move somewhere new for awhile. I feel like i learned so much about who i was during those times. Now I travel much less frequently but I’m not sore about it, because I jam-packed so much life experience into a few short years.
• Asleep_Panda_7482: Not having everything figured out. Your 20s are basically the tutorial level

Doctors of reddit, what was the biggest medical mystery/anomaly that you have come across? (r/AskReddit)

• catrosie: Had a patient who was being treated for low BP by her PCP but her blood pressure continued to be low so she was sent to cardiology where we did a work up but couldn’t find anything wrong. BP continued to be low even maxed out on midodrine. I checked both arms, BP was 80/40 on the left, 180/100 on the right. Checked her carotids and sure enough I heard a bruit. Sent her for a scan and we found she had subclavian steal syndrome and significant stenosis to the left arm arteries. She was being treated for hypotension for months when she actually had severe HYPERTENSION but they had been checking the wrong arm. Sent her to a vascular surgeon who cleared her arteries and I got her on antihypertensives and she stabilized! Now I tell everybody to ALWAYS check BOTH arms if something seems off
• Amadeusodo: I had a patient once come in with tinnitus and on a hunch decided to check an aspirin level - it was sky high and we got her into emergent dialysis. Super lucky catch.
• Racazuzu: This didn’t happen to me, but to my brother when he was in med school & dissecting his first cadaver. As they started working, my bro & his group were getting more & more freaked out because they couldn’t find certain structures where they were supposed to be. It wasn’t until they cracked the sternum & saw the heart on the right side of the body that they realised this person had situs inversus - a condition where all the organs in the torso & abdomen are essentially flipped. It’s pretty rare and odd but doesn’t pose a risk to health, and some people go through life without even knowing they have it.

Who is the most hated comedian among comedians and audiences? (r/AskReddit)

• Due-Amoeba-1519: Carlos Mencia managed to make joke-stealing so blatant that even other comics who usually stay quiet started calling him out by name.
• majorjoe23: I know the MST3K crew hated Gallagher. Supposedly he went through Joel Hodgson’s prop trunk backstage at a show, looking for ideas.
• eyeofnyx: Carlos Mencia is a known joke thief and his show was a rip off of Chapelle Show, and not good.

Spent 90% of my last interview trying to prove I’m not cheating. (Blind)

• Fuitti (ByteDance): Sorry to say, there’s a big chance your friend is right. And you should fix your communication problem before your next interview. Instead of being pissy about it, ask your friend to mock with you, or pay someone to mock with you, or use a service like apexІntervіеwer. It’s how I eventually landed an offer.
• BbUW43 (Yelp): Happened to me… 45 minute interview went on for 1.5 hours. I solved the problem in time with optimizations, but spend the rest of the time convincing the interviewer that I know what I am doing. Still got a reject.
• hAvD08 (TikTok): Regardless of these new cheating tools, communicating is just as, if not more important, than being able to solve the technical question. Even before AI, if you solved a question without asking any questions or even explaining yourself clearly, even if you solved the question correctly, that would be a red flag.

Uber just cut 3,300 jobs (Blind)

No AI until high school: NYC schools announce major classroom technology overhaul (r/technology)

• Salt_End_4275: In the 1980s and 90s, we learned about computers and all of the Windows applications in school. We learned how to type, how to use search engines, and also how to search a library. My children learned NONE of this in school, within the past 10 years. No document processing. No typing. They have had to learn by doing, but you still have many kids typing around 10 words per minute. My kids have used tablets and laptops, sure, but they weren’t taught how to use them, how they work, how to take care of them, etc. While I’m happy to have done that teaching myself, it’s a sad state of affairs that schools don’t teach those basic skills and knowledge anymore, when it is more relevant than ever.
• Otherwise-Anxiety815: They need to treat AI use in schools the way they treated plagiarism when I was growing up. Stop messing around.
• HakuohoFan: Lol, yeah, just give them access once they’re in high school because all high schoolers are know for their impulse control.

SEN BERNIE SANDERS: Yes, we must hit the pause button on AI before it is too late (r/technology)

• Randvek: “Old man yells at cloud” is rarely this literal.
• IlIlIlIllllIIliIILll: Id rather we hit the “pause button” on the bailouts of big business when none of this unproven technology they went all-in on economically pans out as advertised.
• iamagainstit: what would “hitting the pause button” actually mean? These models are already out there, both from the big companies and as open weight models. Are you going to make it illegal for people in the U.S. to do any further CS research on AI? Like what does it actually look like in practice?

NASA’s Nancy Grace Roman Space Telescope began as an instrument meant to look down at Earth, not out into the universe. Its 2.4-meter mirror was built for a U.S. surveillance program that collapsed after severe delays and cost overruns. The National Reconnaissance Office no longer needed the hardware, but NASA did. That unlikely transfer gave astronomy a Hubble-class telescope whose unusually wide view could transform the study of dark energy, dark matter and planets beyond the solar system.

Techmeme surfaced OpenAI’s September 3 launch post, “GPT-6 Astra: A new generation of intelligence.” The release matters less as another benchmark leaderboard than as a deployment threshold: OpenAI is putting a model built to operate computers, browse, code, and carry out long professional workflows into ChatGPT, Codex, the API, and Amazon Bedrock while simultaneously classifying it as the first model to reach the company’s Critical level for cybersecurity capability.

US health officials exclude measles-related deaths in Pennsylvania from counts | US healthcare (r/news)

• steve_ample: If you don’t count them, they do not exist. Some people forgot to empty the stupid ideas recycling bin.
• sck178: I hope this is the dumbest thing I read today. This admin is a joke. Too bad the joke is dangerous and unfunny
• DonManuel: Like children closing their eyes so nobody can see them.

Would you quit your job forever right now (and never be allowed to work again) if someone gave you a guaranteed \$2,000,000 lump sum? Why or why not? (r/AskReddit)

• TrainingSword: Two million doesn’t stretch as much as it used to especially in america
• Hi-Im-High: No. It’s not enough

Police of reddit, what is something that is not illegal but most people don’t do it thinking it is? (r/AskReddit)

• dichron: In most places it is not illegal as a pedestrian to cross the street outside of designated crossings (“jaywalking”). The caveat is that you cannot impede traffic or otherwise endanger other people or yourself
• Imdoingscience: To be completely honest, the biggest thing people appear not to understand is that you should just shut all the way the fuck up. You will never talk your way out of an arrest. You can easily talk yourself into either extra charges or a conviction. In the US, it’s not just legal but entirely your right to just… not talk to the people who are trying to put you in jail.
• HelpILiveInPennridge: My dad was a lawyer. He wasn’t a cop hating lawyer at all. If I ever had a run-in with an authority figure he’d ALWAYS take their side. But I’ll never forget his advice. He told me: you are better off asking a circus clown for a legal opinion than a cop. At least a circus clown doesn’t think they’re an expert.

What personality traits do you find exhausting to deal with? (r/AskReddit)

• Silly_Accident3137: Constantly trying to one-up everyone to prove you’re the smartest in the room. Please just chill
• Express_Preference_3: Only talks about themselves. Never asks questions about other people
