Is Alex wang from Scale AI legit (Blind)

• sfvq47 (Amazon): i mean he was MOP and on us physics team so he is fs genius
• hugMePls (Microsoft): He was the tech lead of quora at 16, someone also mentioned an international Olympiad as well. Joma tech actually has a video where he talks about being interviewed by him at 19. Dude’s cracked, unbelievably so.
• vristotle (Microsoft): Being good at high school math competitions isn’t the same as being a good leader. There are many posts on here talking about how inexperienced he is with real AI work and how inept of a leader he is. Not surprised, he seems very immature and grew up with a silver spoon

Amazon INTENSIONALLY leaks layoffs (Blind)

• nthin2lose (SentinelOne): Amazon knows how to keep everything toxic.
• Jefry (Salesforce): They also stack rank by spelling performance.
• liberat3d (ZenBusiness PBC): It’ll be ironic if they cut someone tomorrow who fixes their outage issues today.

Mass Layoffs Have Consequences (Blind)

• RowdySWE (Block): Elon basically gave CEOs permission to start doing this when he ripped apart twitter and it was still functioning.
• crazzak (Microsoft): Employees don’t feel invested in companies that throw them away like trash the second it saves them a buck; this leads to less innovation and decline in quality.
• JNSx07 (Manhattan Associates): But no one really cares… CEO only cares about quarterly results and share value.

Cloudflare lays off 1,100 people (r/technology)

• davidcelis: I know it’s probably automatic because of the similar titles, but hitting the bottom of the layoff announcement only to be recommended their post from last year about hiring 1,111 interns in 2026 is a reaaal bad look
• millanstar: So we can expect a major outtage in the coming months
• Albert3232: Being employed in the tech industry must be so stressful. Imagine having a mortgage to pay and knowing you can be laid off at any moment.

PSA: Instagram Encrypted Messaging Ends on Friday, May 8 (r/technology)

• Currentshop333: If this actually happens then a lot of people are going to realize how much they relied on encrypted DMs without even thinking about it. Feels like every platform keeps moving backwards on privacy lately.
• FlukyS: At that point they might as well remove messaging
• holyoctopus: Honestly anyone using any Meta products today and expecting privacy are out of their minds. Delete your Facebook and Instagram, stop using meta products if you care about this.

Apple is putting cameras in AirPods. What could possibly go wrong? (r/technology)

• loves_grapefruit: Why are they so obsessed with cameras? Why does it all have to lead to cameras??
• dichron: God that article was painful to read. Why do AI writers always have to say the same thing multiple times over in slightly different ways?
• VincentNacon: Did they forget that people have mid-to-long hair?

I’ve been working with a Vibe Coder and this has been my experience (r/webdev)

• AlmightyLarcener: I’m completely in the same situation. PRs with 2000 line changes. One of them contains Sentry.io, even though we do not use it. Every response is from Claude, I don’t even argue any more.
• shakjj: Sounds like YOU are vibecoding (by working with him). He is just a proxy. Sad to see people comfortable on that role.
• GASd-: people shipping code without any architectural considerations are nightmares

Looking for feedback on AI content in r/programming and the April no-AI trial (r/programming)

• PracticeAccording274: the april trial felt pretty good tbh, less noise in the feed and more actual programming discussions instead of endless “will ai replace us” posts
• davenirline: Oh Please keep it. I think it’s the only one sub that I go to that does this.
• Computer991: It was amazing, please keep it

Difficulty: HARD

Problem: Guess the Word

Problem gist

This is an interactive guessing problem. There is a hidden six-letter word inside the given list, and the only way to learn about it is to call master.guess(word). The API returns how many positions match the secret exactly. For example, if the guess and secret have the same letter in positions 0, 2, and 5, the response is 3.

Difficulty: MEDIUM

Problem: Word Search

Problem gist

The problem gives a 2D grid of characters and a target word. The task is to decide whether the word can be formed by walking through adjacent grid cells. Each step may move up, down, left, or right, and the same cell cannot be used twice in the same word path.

Problem: Remove Duplicates from Sorted Array II

Problem gist

The input is a sorted array nums. The task is to modify it in place so every distinct value appears at most two times, while keeping the original relative order of the remaining values. The function returns k, the length of the valid prefix. Anything after index k - 1 does not matter.

Quick facts

• Difficulty: MEDIUM
• Problem: Subarray Sums Divisible by K
• Main tags: Array, Hash Table, Prefix Sum

What the problem is asking

Given an integer array nums and an integer k, count how many contiguous subarrays have a sum divisible by k.

The word “contiguous” is the key constraint. A valid answer must count ranges like nums[left:right + 1], not arbitrary subsets. The same element can participate in many different subarrays, and overlapping ranges are counted separately.

What happened

NVIDIA’s official technical blog published Achieving Peak System and Workload Efficiency on NVIDIA GB200 NVL72 with Slurm Block Scheduling, a post about making classic HPC scheduling understand rack-scale AI systems where NVLink locality is no longer a soft preference.

The core issue is that GB200 NVL72 changes the unit of useful allocation. A single rack spans 72 Blackwell GPUs across 18 compute trays, connected by fifth-generation NVLink into one coherent high-bandwidth domain. Inside that domain, each GPU has access to very high bidirectional bandwidth, and the rack reaches an aggregate bandwidth scale that makes intra-rack communication feel like a first-class part of the machine. Once a workload crosses outside the NVLink domain, communication falls back to the external fabric, such as InfiniBand or Ethernet, with a much lower bandwidth profile. That creates a sharp performance cliff rather than a smooth locality gradient.

A moon that keeps getting more interesting

This article returns to one of the most compelling places in the solar system: Enceladus, the small icy moon of Saturn that sprays material from a hidden ocean into space. The basic reason for its scientific appeal is straightforward. Scientists do not have to drill through the ice to sample the ocean below. Enceladus is already doing part of the work for them by venting plumes of water and ice grains from fractures near its south pole.

What happened

Techmeme surfaced this May 8, 2026 story in its Techmeme item, and the original article is The Wall Street Journal’s Apple, Intel Have Reached Preliminary Chip-Making Agreement.

Apple and Intel have reportedly reached a formal agreement for Intel to manufacture some chips for Apple devices. The exact products are not yet clear, which is an important caveat: this could range from a limited component order to a more meaningful role in Apple’s device roadmap. Even with that uncertainty, the deal is notable because Apple has spent years relying heavily on Taiwan Semiconductor Manufacturing Company for the advanced chips used across iPhone, iPad, Mac, and other products.

This summary covers The Economist’s April 25th, 2026 International article listed in the contents as America's arms industry and published under the headline Shooting to prominence.

The article argues that America’s defence industry is entering a disruptive phase. The Pentagon still relies on giant contractors such as Lockheed Martin, RTX and Northrop Grumman, but war is changing faster than their procurement habits. Cheap drones, software-defined weapons and battlefield AI are making older, costlier systems look ill-suited to some of the conflicts the United States is now fighting or preparing for.

CNN founder Ted Turner, a pioneer of cable TV news, dies at 87 (r/news)

• WREPGB: He’s been alive this whole time?
• hybridaaroncarroll: One thing I’m grateful for what he accomplished: TCM. Saving many old movies from the dustbin of celluloid history was a massive win for nerds like me.
• RipErRiley: The guy just dipped his feet into pro wrastlin and dethroned Vince McMahon temporarily. Impressive. Cable news? Meh.

South Korean judge who hiked ex-first lady’s jail sentence found dead just 8 days after sentencing (r/worldnews)

• HarlequinKOTF: Not suspicious at all.
• TheoreticalResearch: Creepy ass woman, creepy ass family.
• Grimtongues: Shin Jong-oh beat himself to death, dumped his body into a flower bed outside the courthouse, and then wrote a suicide note saying he was leaving this world voluntarily… seems legit

Alleged suicide note written by Jeffrey Epstein unsealed by federal judge (r/news)

• ScottScanlon: And this thing just magically appears six years later. Totally believable.
• mrdominoe: Was it written on some bullets?
• sirdodger: They unsealed that pretty quickly after they found it. Funny that the rest of the files are going to remain sealed and redacted until it’s been so long that their provenance becomes in doubt and any witnesses and corroborating evidence are long gone.

What scientific discovery sounds fake but is 100% real and still freaks you out? (r/AskReddit)

• Critical_Physics_770: Prions
• cmayfi: Ants measure distance by counting their steps. Scientists proved this by taking some ants out of a line and putting tiny stilts on them. Those ants then over shot the food source they were going too
• scary_warrior: Grizzly bears run as fast as the average horse

TIL Krakatoa’s eruption was estimated to be at 310 dB, the loudest sound ever. Well above the typical max sound limit of 194 dB (r/todayilearned)

• mryazzy: People forget decibels are logarithmic, not linear. This doesn’t mean twice the noise generated by a rock concert. It is many orders of magnitude louder.
• WontThinkStraight: How many decibels would the asteroid that killed the dinosaurs have been? Feels like that would have been louder.
• SpunNumeroUno: I wonder what it actually sounded like, just an explosion or something more complex… Hmm
