Xitter post from Clement Delangue, boss of Hugging Face: We suspected last week's cyberattack might have come from a frontier lab, given the sophistication of the agent. Turns out it did!

We've spent the past 24 hours working closely with the @OpenAI team (thanks!), and we strongly believe there was no malicious intent on their part. It's quite mind-blowing that all of this happened autonomously!

The investigation is ongoing, and we'll share more learnings from what might be the first incident of its kind!

Cover album for "Acheron" by Mechina. An Earth-like planet in red hue is in the background, and some symbols are in the front. The symbols looks like portals that show a mountainous landscape with pine trees.

Me crossing the finish line, with both my arms raised with the horns. I am looking angry, straight into the camera, with my tongue out and down.

The others around me just try to cross the finish line without any attempt of shenanigans.

My battle station. It has a big desk mat with a scary foresty vibe, and on top of it is a split keyboard (Halcyon Elora) with two wooden palm rests. There are also 7 fans on top of the desk mat, some 140mm, some 120mm, some black and some with the Noctua caramel/brown combination. At the right of the desk mat is a small black computer case, approximately 25 cm high and 17 cm wide. On top of the case sits an eight fan, which is 200mm and has the Noctua caramel/brown color as well. All the fans are on. The computer screen is put on top of a black monitor stand. The screen is off.

The album cover for Alcázares by Impureza: It depicts a courtyard in an Alcázar, with four stone statues looking towards a sepulchre. The statues look kinda vikingy, though they're probably aimed to depict "hooded" knights. They all hold swords with both their hands right in front of them, tip pointing down.

The lid of the sepulchre/sarcophagus is opened, and a vengeful ghostly conquistador comes out of it.

Above the tower of the Alcázar is some sort of sky vortex, though the rest of the sky seems unaffected by its presence.

Album art with no text on it. An "alien" world where hands with claw-like fingers come up from the ground. In the middle of the cover is a fissure, with teeth on both sides. Some of the hands seem to catch spirits that are falling from the sky, and some of the spirits are connected by a white string.

Album cover for "Children of Eve" by Nightfall. It has a painted style. A woman with flowing hair embraces a red-toned/bloodied man with long hair with a fearful look. The man is part of a group of red-toned/bloodied men, the others looking more like they're in a rage or anguished. The image is set against a cloudy sky, the woman's hair looks like it melds with the sky.

Several new metal albums and EPs were released this week, including works from Cryptopsy, Heaven Shall Burn, and Inhuman Condition. Additionally, there are upcoming releases from To The Grave, Aversions Crown, and Grand Cadaver in the coming weeks.
Here's a more detailed look:

This Week's New Releases (June 27, 2025):
Cryptopsy: An Insatiable Violence
Heaven Shall Burn: Heimat
Inhuman Condition: Mind Trap

Screenshot of a Google search for `"you wildflower" witch club satan`.

Two videos are the first results, named "Witch Club Satan - You Wildflower (Official Music Video)" and "YOU WILDFLOWER releases on Midsummer, night to the 24th ...".

Then there's an AI summary that says the following:
The song "You Wildflower" is not a known song by the band Witch Club Satan. Witch Club Satan is a feminist black metal band known for songs like "Obsidian Ritual" and "Vomit Upon the Altar of God", but they don't have a song titled "You Wildflower". It's possible there's a misunderstanding or the song is by a different artist.

"Obsidian Ritual" and "Vomit Upon the Altar of God" are not titles of any Witch Club Satan songs.

The tunnel is facing the wooden wall beneath it, leading air into an air duct at the bottom of the wall. There is a hammer at the top of the tunnel to keep it in place, head down and the handle poking straight up.

What are the limitations of Dijkstra's algorithm?

ChatGPT:

Dijkstra's algorithm, while powerful and widely used for finding the shortest path in a graph, has several limitations:

Non-negative Edge Weights:
Dijkstra's algorithm assumes that all edge weights are non-negative. It cannot handle graphs with negative edge weights, as this can lead to incorrect results or infinite loops.

Efficiency with Dense Graphs:
In dense graphs, where there are many edges compared to the number of vertices, Dijkstra's algorithm can be less efficient. Its time complexity is O(V^2) with a simple implementation using arrays, or O((V+E)log⁡V) with a priority queue and adjacency list, where V is the number of vertices and E is the number of edges. For dense graphs, where E is close to V^2, this can be quite slow.

Single-Source Limitation:
Dijkstra's algorithm is designed to find the shortest path from a single source vertex to all other vertices. If you need shortest paths for multiple sources, you have to run the algorithm multiple times, which increases the computational cost.

Inefficiency in Unweighted Graphs:
For unweighted graphs, Dijkstra's algorithm is less efficient than simpler algorithms like Breadth-First Search (BFS), which can find the shortest path in O(V+E).

Dynamic Graphs:
Dijkstra’s algorithm doesn’t handle dynamic changes to the graph (like adding or removing edges or vertices) efficiently. If the graph changes, the algorithm typically needs to be rerun from scratch.

Memory Consumption:
In large graphs, Dijkstra's algorithm can consume a significant amount of memory to store all vertices and edges, especially if the graph is dense.

Lack of Path Enumeration:
The algorithm finds the shortest path but does not enumerate all possible paths. For applications where multiple paths or all possible paths are needed, additional logic is required.

How can I find the shortest path in a tree? And how many paths between two nodes are there in a tree?

In a tree:
1. Finding the Shortest Path:

The shortest path between any two nodes in a tree is unique because a tree is an acyclic connected graph.
To find the shortest path between two nodes u and v, you can use the following approach:
Find the Lowest Common Ancestor (LCA) of u and v. The LCA is the deepest node that is an ancestor of both u and v.
The shortest path from u to v is:
Distance(u,LCA)+Distance(v,LCA)

This can be achieved using depth-first search (DFS) to calculate the depth of nodes and identify the LCA efficiently with techniques like binary lifting for large trees.

If we are able to reduce the all-pairs shortest paths (APSP) problem to the 3-SAT problem, it would imply a significant computational relationship between these two problems, specifically:
Implications of the Reduction:

APSP is in NP:
The 3-SAT problem is NP-complete, which means it belongs to the class NP (nondeterministic polynomial time).
If APSP can be reduced to 3-SAT, it shows that APSP is at least as hard as 3-SAT under polynomial-time reductions.
Since 3-SAT is in NP, and we can reduce APSP to 3-SAT, APSP would also have to be in NP. This suggests APSP is solvable in nondeterministic polynomial time.

Potential NP-Completeness of APSP:
If APSP can be reduced to 3-SAT in polynomial time, and we already know that 3-SAT can be reduced to any NP problem (as it is NP-complete), then APSP could be shown to be NP-complete.
To prove APSP is NP-complete, two things are required:
APSP is in NP.
Every problem in NP can be reduced to APSP.
If we have a reduction from APSP to 3-SAT, and 3-SAT is NP-complete, then by transitivity of reductions, APSP would be NP-complete, provided that APSP itself is in NP.

Can you solve the recurrence T(n) = 4T(n/2) + n^2 * log(n) and return the answer in theta-notation?
ChatGPT sa:
ChatGPT

Yes, I can solve the recurrence T(n)=4T(n2)+n2log⁡nT(n)=4T(2n)+n2logn using the Master Theorem.

The recurrence is in the form:
...

Example:

Input: P=[10,20,30,40,30]P=[10,20,30,40,30]

This means:

A1A1 is a 10×2010×20 matrix.
A2A2 is a 20×3020×30 matrix.
A3A3 is a 30×4030×40 matrix.
A4A4 is a 40×3040×30 matrix.

Output: The minimum number of scalar multiplications is 30000.
Explanation:

The optimal way to parenthesize the matrices is ((A1A2)(A3A4))((A1A2)(A3A4)) which results in 30000 scalar multiplications.
