I'm curious about something.

Most alarm and reminder apps basically do the same thing: set a time, get a notification, dismiss it.

But what do you actually wish they did better?

For example:

Smarter alarms based on your routine

Alarms that require an action before dismissing

Location-based reminders

Voice-based control

Better daily activity reminders

Those are just examples. I'm more interested in the problems you personally have with alarm/reminder apps.

What feature would genuinely make you switch from the alarm app you're using now?

I recently started a new Instagram account focused on AI, software development, and interesting tech experiments.

I’ve only posted 2 reels so far, so I know it’s very early, but I’m already questioning whether I’m approaching the content in the wrong way.

My current idea is to make content around things like:

AI tools and experiments

Software development

Interesting tech/AI facts

AI + coding

Things I build or test

But I’m not sure about a few things:

1. Is the niche too broad?

Should I focus specifically on AI, software development, AI for developers, etc.?

2. Is the content format wrong?

Does this type of talking-head/handheld content actually work for tech content?

3. What do you think is missing from the videos?

Hook? Editing? Topic selection? Personality? Value? Something else?

4. If you saw this profile with 0 followers, would you follow it? Why or why not?

I’m genuinely looking for blunt feedback, not compliments. If the niche, content style, profile, hooks, or positioning are bad, I’d rather know now than waste months doing the same thing.

Here are screenshots of the profile and my first two reels.

Please be brutally honest. What would you change if this were your account?

Is it normal when learning DSA for the first time to know which data structure or general approach to use, but still end up creating a completely different algorithm than the standard solution?

​

For example, I can often recognize things like:

​

* HashMap problem

* Binary Search problem

* Two Pointers problem

​

But when I actually start solving it, I sometimes come up with my own logic instead of the standard approach. The solution may even work for some test cases, but later I realize the accepted solution uses a different idea or handles edge cases more cleanly.

​

A recent example was with Binary Search variants. I correctly identified that Binary Search should be used, but I created my own logic for finding the first occurrence instead of the common solution. After testing, I realized I was basically solving a slightly different problem.

​

Is this a normal stage of learning DSA and pattern recognition? Did you also create "custom" algorithms when you were a beginner, even when you knew the correct data structure or technique to use? At what point did you start naturally arriving at the standard solutions?

I'm 18M and have been experiencing the following symptoms for quite a while:

- Tingling / pins and needles sensations

- General weakness and fatigue

- Brain fog

- Memory issues (sometimes forgetting things)

- Frequent mouth ulcers

- Headaches

- Occasional numbness sensations

Recent test results:

Vitamin B12:

- 133 pg/mL (Reference: 192–827)

CBC:

- Hemoglobin: 12.9 g/dL

- RBC: 5.75

- MCV: 67.5 fL (low)

- MCH: 22.4 pg (low)

- RDW: 15.1%

Previous CBC about 2–3 weeks earlier showed similar findings:

- MCV ~67

- MCH ~22

IgE:

- 30.49 kU/L (normal)

A physician started me on a B12 supplement (NVM-M12 OD), but I still have neurological symptoms and headaches.

My questions:

1. Could B12 deficiency alone explain these symptoms?

2. Since my MCV is very low, should I investigate iron deficiency (Ferritin) or thalassemia trait?

3. Should I get Serum Folate, Ferritin, TSH, and Vitamin D tested next?

4. Is oral B12 usually enough for neurological symptoms, or should injections be discussed with my doctor?

Any insights from people who had similar lab results would be appreciated.

Hi everyone,

I recently got my blood test done and my Vitamin B12 level is 133 pg/mL, which seems quite low. I’m vegetarian, so I think diet may be one reason.

Symptoms I’ve been having:

Fatigue / low energy

Sometimes tingling or weird sensations

Brain fog / difficulty focusing

Occasional weakness

My doctor suggested supplements, but I also wanted real experiences from people here.

What B12 supplement worked best for you?

Methylcobalamin or Cyanocobalamin?

Tablets, sublingual, or injections?

How long did it take to feel better?

Any vegetarian-friendly affordable options?

Also, if your B12 was around this level before, how long did recovery take?
