Alright, future engineers!
**Matrix Multiplication:** Combines matrix transformations or weighted sums.
Ex: For `A` (m x n) & `B` (n x p), `(AB)_ij = sum(A_ik * B_kj)`.
Pro-Tip: #Cols in first MUST equal #Rows in second! Otherwise, undefined.

SUM() OVER (ORDER BY...) считает не то, что вы думаете: кадр оконной функции

Привет, Хабр! SUM() OVER (ORDER BY ...) часто выглядит как очевидный способ посчитать нарастающий итог, пока в данных не появляются одинаковые значения ключа сортировки. В этот момент результат начинает «прыгать», LAST_VALUE возвращает текущую строку, а запрос формально остаётся корректным. В статье разбираем скрытую причину таких сюрпризов — кадр оконной функции: как база подставляет его по умолчанию, чем ROWS отличается от RANGE и какие детали стоит проверять, чтобы аналитические SQL‑запросы считали именно то, что вы ожидали.

Why Incline Rows Matter? 🤔

Treat the incline row as a controlled tension-building movement, not a momentum lift, and it can be a strong tool for improving posture, back thickness, and better mind-muscle connection.

Dumbbell incline rows are a great way to train the upper back with more control and less lower back involvement. 🔄

The bench gives you support, which makes it easier to focus on the muscles doing the work instead of turning the movement into a body swing.

Alright, let's nail this Linear Algebra concept!

Matrix multiplication combines rows of the first matrix (A) with columns of the second (B). Ex: For A (m x n) & B (n x p), A*B results in an (m x p) matrix. Pro-Tip: #cols in A MUST match #rows in B for A*B to be possible! Order matters.

Single Arm Smith Machine Bent Over Row 1️⃣↕️

This is a sneaky-good movement for dialing in back engagement and fixing side-to-side imbalances.

—

✅ Think: pull shoulder blade back and down first, then row.

✅ Elbow path: Drive elbow toward your hip, not straight up.

✅ Top position: Elbow slightly past torso, lat fully shortened, pause 1–2 seconds.

✅ Lower slowly: 2–4 second eccentric to maximize mechanical tension.

↕️ Dumbbell Batwing Rows 🦇

The Batwing Row isolates the rhomboids, middle traps, and rear delts, teaching you to pull with precision and maintain tension at peak contraction.

Pull both dumbbells straight toward your ribs, elbows tight to your sides.

Think about driving your elbows behind your body rather than just lifting the weights.

↕️ Dumbbell Alternating Bent Over Rows 💪

An excellent workout leading to developing the muscles of the lats and the back overall

👉 Drive your right elbow back, keeping it close to your torso. Focus on pulling with your back (lats and rhomboids), not just your arm.

👉 Slowly return the dumbbell to the starting position with full control.

3 easy exercises

1. #Squats : A version of a squat is relevant to everybody because everybody needs to take themselves to the washroom
2. #Rows : We take for granted our ability to carry shopping, put things in cupboards, even brush our hair. Push and pull movements are key
3. #Pushups : Countertop push-ups help us retain upper body strength

Fall in Wine Country

My favorite time of year to photograph the grapevines of Northern California is during the fall. The grapes have all been picked and crushed. The short days signal the vines it is time to shut down and their leaves go through the fall color change.
I captured this in Suisun Valley, just east of Napa Valley.

Do I have anyone on this feed who #rows or #sculls? If so, let me know. Wife's small club is hosting a virtual #regatta next month (with your own Concept 2 or compatible erg). And unless overridden by the club, one of my #alligator pictures will be incorporated into the medals!

Would love to see you compete!
