L-theanine makes me calmer and more focused, but less vibrant?

​

I’ve been taking L-theanine for social anxiety. I also strongly suspect I have ADHD, though I’m not diagnosed. It runs in my family, and the signs seem pretty obvious.

L-theanine makes social situations a little easier for me to handle. I feel calmer, more focused, and less overwhelmed.

The strange part is that my partner can tell whether I’ve taken it that day just by looking at me. She says I seem less vibrant and expressive, stare more blankly, and come across as distant or unaffectionate. Her slightly dramatic description is that I look like a psychopath from a movie.

I don’t feel emotionally flat or numb, though. From my perspective, I’m simply calmer, less animated, and more sharply focused.

Has anyone else experienced this, where L-theanine helps internally but noticeably changes how expressive or emotionally present you seem to others?

How to sandbox fs and network?

I'm planning to use Pi as a sensitive data analyser, but the data must remain on the intranet.

I thought running it inside a VM with a proxy would be the safest option, but I can't install a VM in my current environment.

I do already have Docker available. Is there a good way to sandbox filesystem (like; can we bind data folder read only) and network access with Docker instead? Pi shouldn't access anything else; just specified paths, and some specified local ip addresses.

Cheap DIY CR-box with 4x iKEA FÖRNUFTIG filters + 14" automotive fan. Does this design make sense?

Im trying to build a very simple and cheap particle air cleaner for a ~40 m² apartment, mainly for dust, pollen, mold spores and PM2.5.

The current design is:

- 4 x IKEA FÖRNUFTIG particle filters

- approx. 390 × 250 mm each

- arranged as the four vertical walls of a square box

- filters joined directly edge-to-edge with tape, no extra corner posts

- Solid cardboard bottom, completely sealed

- Cardboard top plate with a circular fan opening

- 1 x universal 14" automotive cooling fan mounted on top, exhausting upwards

Fan specs:

- Diameter: 14" / ~356 mm

- 12 V DC

- 7 A

- 2200 rpm

- Rated free-air airflow: 900 m³/h

- So roughly 84 W electrical draw at full power

The idea is that all four filters are in parallel, so the total filter face area is roughly:

4 x 0.39 x 0.25 = 0.39 m²

The fan opening itself is roughly 0.10 m², so the combined filter face area is about 4x the fan disc area.

I'm skipping activated carbon for now because I mainly want high particle CADR and low cost.

My questions:

  1. Does this geometry make sense, or is there an obvious airflow problem?

  2. Is this type of 14" automotive radiator fan likely to perform reasonably against the pressure drop of four FÖRNUFTIG filters?

  3. Would you mount the fan directly on the top plate, or add a short plenum/shroud?

  4. Are four FÖRNUFTIG filters enough filter area for this fan, or would you go larger?

  5. Any issue with having the bottom fully sealed and all intake coming through the four side filters?

  6. Has anyone measured static pressure / airflow curves for similar automotive fans in CR-box builds?

  7. Would PWM speed control be a sensible way to reduce noise at night?

I’m trying to keep the whole thing around 80-100 bucks and make it buildable with basically cardboard + tape + a 12 V PSU.

Any obvious mistakes before I buy the parts?

Looking for a code review of a TypeScript CRUD API with role-based access control

I recently got rejected after completing a technical task for a Senior Node.js role.

The project involved TypeScript based CRUD API, role management, authorization, and dependency handling. The feedback suggested that some of my architectural choices made dependencies less explicit and affected testability and maintainability.

I cannot share the original task description or repository publicly here as a post, but I can send sanitized parts privately to anyone willing to review them.

I am mainly looking for honest feedback on the architecture, dependency management, code structure, testability, and whether the overall approach meets senior-level expectations.

Would anyone be open to taking a look privately? Please comment or DM me.

Looking for private feedback on a TypeScript backend technical task

I recently got rejected after completing a technical task for a backend role.

The task involved a CRUD API, role management, authorization, and related backend structure. I can not share the task description or repository publicly because of confidentiality, but I can send a sanitized version privately to anyone willing to review it.

I am mainly looking for honest criticism of the architecture, code quality, API design, overall approach, and anything else that may have weakened the submission.

Would anyone be open to taking a look if I send it privately? Please comment or DM me.

I couldn't be sure if what I want is falls under Rule 5 or not, but if it is, please remove it.

Thanks in advance.

Newbie here with satake 28cm 3mm carbon steel pan

It says pre-seasoned? The label says wash gently and boil once and you're right ready to go. What do I do? Can I seal an entrecote right away and sautee garlic and peppers?

If so, How much oil do I need to use? Same as stainless steel?

Thanks.
