A line chart titled "Daily Download Quantity of open-spiel package - Python Minor". The x-axis represents the Date, ranging from December 22 (12-22) to June 15 (06-15), and the y-axis represents Downloads, ranging from 0 to over 15,000. A legend lists various Python minor versions (from 3.6 to 3.15, plus Null) corresponding to different colored lines. The data shows that version 3.12 (green line) dominates for the first few months, steadily fluctuating between 2,000 and 7,500 downloads. The most significant anomaly is a sudden, massive spike for version 3.13 (red line) in early May, reaching nearly 18,000 downloads. Following this peak, version 3.13 remains highly volatile but at a noticeably higher baseline, frequently competing with or surpassing version 3.12. The majority of the other Python versions remain consistently near zero throughout the entire timeline.
A line chart titled "Daily Download Quantity of tpu-info package - Overall". The x-axis represents the Date, ranging from December 22 (12-22) to June 15 (06-15), and the y-axis represents Downloads, ranging from 0 to 120,000. A legend indicates two categories: "With_Mirrors" (blue) and "Without_Mirrors" (orange). The visible data shows a highly volatile zig-zag pattern, frequently oscillating between valleys of roughly 20,000 and peaks up to 120,000 downloads, before experiencing a sharp, sustained drop to below 20,000 downloads starting in late May.

At the bottom of the list are the options 'Continue' and 'Reset'. To the right of the main menu options, blue help text explains the currently highlighted selection: 'This is the option one adjusts to change the language for the current system'. At the very bottom of the screen, outside the light-colored window, white text gives keyboard navigation instructions: '↑↓=Move Highlight <Enter>=Select Entry'."</Enter></English>

Across the street, another Cueball-like guy is coming from a building walking towards the pedestrian crossing across from Black Hat.] Black Hat: There's a certain type of brain that's easily disabled. Black Hat: If you show it an interesting problem, it involuntarily drops everything else to work on it. [The Cueball-like man across the street is about to enter a crosswalk, which is seen from right behind Black Hat in his chair, holding onto the sign, which is still pointing down. Cueball is looking on.] Black Hat: This has led me to invent a new sport: Nerd Sniping. Black Hat: See that physicist crossing the road? [Black Hat lifts up the sign when the physicist is in the middle of the street, halfway across the pedestrian crossing.] Black Hat: Hey!

Two nodes, a knight's move apart, are marked with red circles in the 3rd row 2nd column and the 2nd row 4th column.] Sign: On this infinite grid of ideal one-ohm resistors, Sign: what's the equivalent resistance between the two marked nodes? [The Cueball-like physicist has stopped, a hand to his chin.] Physicist: It's... Hmm. Interesting. Maybe if you start with... No, wait. Hmm... You could— [In another frameless panel, a ten-wheeled truck is zooming past from the right, apparently going through the spot where the physicist just stood.] Truck: Foooom [Cueball looks down on Black Hat in chair at the curb, again holding the sign down. He lifts one hand up while replying.] Cueball: I will have no part in this. Black Hat: C'mon, make a sign. It's fun! Physicists are two points, mathematicians three.

Screen recording of black screen of 'AI Chat'. Starts by selecting model 'Gemma 4B E4B Gemini Nano via AICore' and opening configuration. Typing "How would you briefly explain what SMOTE is in ML?" Response ('Model on NPU'): SMOTE (Synthetic Minority Over-sampling Technique) is a method used in machine learning to prevent model bias when dealing with imbalanced datasets (where one class has significantly more examples than others—the "majority" class). Instead of simply duplicating existing minority examples, it works by: Selecting a minority sample. Finding its nearest neighbors (using the features). Creating new, synthetic data points that lie between the chosen sample and its neighbors. The goal: To artificially balance the classes by increasing the representation of the minority class without simply repeating existing data points.
