Hi all. A small question regarding encoding the position of inputs to a transformer model.

How would you encode a set of sequences to a (bidirectional) transformer? For a sequence we have positional encodings. For a set we can just work without them. What about a set of sequences {s\_1, …, s\_n}, where each s\_1, …, s\_n is a sequence, but their relative order does not matter?

I KNOW people aren’t going to post their working algos online. I was curious if there were examples of full systems online. Like I said they could be total failures from a strategy perspective. Basically just trying to look at the general structure of what a full system might look like.

One of the gaps I kept hitting in SEO audits was the **lack of a clean visual archive** of SERPs across time — especially for high-value commercial queries.

So I built a desktop tool (macOS, Electron + Chromium) that:

\- Accepts a keyword list

\- Automates browser sessions

\- Captures full-page SERP screenshots

\- Saves them locally for comparison

It’s not scraping — it captures what a real user sees, including any A/B variations or local result shifts. Helpful when analyzing SERP volatility or preparing reports for non-technical clients.

Curious how others are handling **visual SERP tracking** — and whether there’s a better way to structure this process.

Can share a demo or the tool if anyone’s interested.

Which one is best to start as a beginner ?

Calling all traders, coders, and especially math lovers.

Let’s approach trading profitability from first principles.

After 10 years of live trading, I’ve been thinking deeply about how to build a logic-based, probabilistic trading model — and finally have a clear problem statement.

📌 But before jumping into solutions, I want to ask:
Does this problem statement make sense?
If we solve it, does it logically lead to a profitable edge?

🧩 The Setup: 5 Variables and 2 Rules

We are trading in any liquid market: CFDs, stocks, crypto, etc.

🎯 The 5 Variables:
• X = Entry level
• Y = Take profit level
• Z = Stop loss level
• P = Probability that price hits Y after X → P(Y | X)
• L = Probability that price hits Z after X → P(Z | X)

⸻

✅ Rule 1:

|X – Y| > |X – Z|
→ Ensures a Reward > Risk (R:R > 1)

✅ Rule 2:

P(Y | X) > P(Z | X)
→ Ensures Target is statistically more likely than Stop

⸻

🧠 The Problem Statement:

Find combinations of (X, Y, Z, P, L) that satisfy Rule 1 and Rule 2.

If both are true, the setup has positive expected value:

EV = P(Y | X) × |Y − X| − P(Z | X) × |X − Z| > 0

That’s it — clean, testable, logic-based.

Would love your thoughts.
• Does this problem definition hold up mathematically?
• Would solving this system — even partially — lead to a trading edge?

Hi everyone I’m planning a trip to San Diego sometime in August I also want to spend at least 3 days in Los Angeles. My question is, is it worth doing a multi city plane ticket? JFK to SAN then LAX to JFK? Is it worth visiting Los Angeles? I would appreciate any recommendations. Thank you.

I’m starting an e-commerce clothing and swim line with my 1 co-founder. While I do want the business to be successful and profitable, I have very realistic standards of the margins that come with this niche. I am not as set on profit as much as I am building my dream brand, and pouring my love for my vision into my passion project. However, I do not want this to be an endeavor that ends up being a net negative and never breaking even. I happen to come from both a fashion AND tech background (model turned SaaS slinger) so I have a decent network that has already gave me a great edge entering into this. Webdev, branding/marketing, model & photographer friends etc. that are very helpful while we’re intending to bootstrap this ourselves (for as long as possible).

Brand and store owners, if you could go back to when you were first starting out, what would you do different? What is the biggest piece of advice you could give me? What do you wish you knew then that you know now?

Super appreciative of any guidance or advice. We just hit the 8 month mark until launch, so everything now counts. 🙏🏼
