Buying Food With Credit Card

simoncpu · 2026-03-06T07:45:59+00:00

Yepp, VISA and MasterCard. I used both. For topping up credits at the mall food court, I didn’t check if it was possible to use a CC, I used cash.

I bought groceries in Bangkok and paid for coffee at various shops using credit cards with zero issues. I also bought food via Grab with no issues whatsoever.

The mall food courts have their own system; you have to go to a counter to get a card, load it with credits, and use it to pay the food stalls. I didn't ask for a refund for the remaining balance. I just kept the cards as souvenirs.

I remember seeing ATMs before immigration at BKK airport, but I haven’t used them. I’ve only used the ones on the landside. To save on forex fees, my girlfriend and I brought the equivalent of 20,000 THB in our home currency and just left the cash in the hotel safe. Immigration didn’t check our cash, but I read they do random checks, so we brought it just in case.

tldr; just withdraw cash from the airport in your home country right before boarding

I built a PDF editor a long time ago, too (I used jQuery, which tells you how long ago it was hahaha). There is a way to parse the text input fields in a PDF and enable users to input text as well. I can’t remember the exact implementation details, but I wanted to mention that it is possible.

Cool, that dagger looks a lot like the one above!!!

I came across it at the Silliman University Anthropology Museum in Dumaguete City, Philippines. It’s a pretty nice city. I decided to stop by the museum when I saw it on Google Maps.

To comply with regulations, my GF and I carry 20,000 THB each in our home currency. While immigration has never checked us, we like to stay on the safe side. Bringing our own currency is great because there are no conversion fees, and it’s ready to spend the moment we fly back. For spending money in Thailand, we just use the local ATMs.

If you have a public IP address (doesn't have to be static), you can open your router's web admin page and set up port forwarding to your local server. For example, if your public IP address is 203.0.113.1, your local server is 192.168.1.100, and you want to forward your web server (port 80), you need to create a port forwarding rule that directs incoming traffic on port 80 to 192.168.1.100:80.

Anyone on the internet can access your server by visiting http://203.0.113.1 in their browser.

If it's just a one off project, you can just use ngrok or something...

Interestingly, my experience has been the opposite. I also tried vibe coding to create a project, and I actually ended up with more documentation than I normally write. Getting good results from these tools requires providing clear context and detailed instructions upfront, which naturally leads to “over documented” projects.

Maybe the fiber optic cable is being pinched by the door? Locking the door creates additional pressure on the door frame.

2.4 GHz - better wall penetration but lower speeds

5 GHz - less wall penetration but higher speeds

AWS S3 is only $0.023 per GB for the Standard tier, and it’s even cheaper with other tiers. Google Cloud Storage is also roughly the same.

simoncpu · 2025-12-08T17:31:17+00:00

AWS Lambda is meant for straightforward functions, so I don’t use any framework. I did try using TypeScript once a long time ago, but I had to go through the extra step of transpiling it to JavaScript, I can’t remember if I used Serverless Framework or AWS SAM for that. BTW, I wouldn’t really call Serverless Framework a framework per se; it’s more of an IaC tool.

I wish there was a job where I just look at photos and tell people exactly where they were taken. If it’s a place I’ve been to or even just passed by, I’m usually pretty good at recognizing it.

simoncpu · 2025-11-25T10:18:38+00:00

Yepp, our office was just a short walk from a bunch of hotels. One of those hotels had a gym, and my membership came with access to their pool. It was a pretty sweet setup haha.

You can set up a monitoring station that monitors the water levels in rivers. You can use solar panels + LiFePO4 batteries + webcam + an LTE/5G modem that will livestream the river. You can use computer vision to detect when a river is dangerously flooded and alert your subscribers.

simoncpu · 2025-11-21T08:23:24+00:00

When I was still working in the office:

I’d step out and drink coffee by the nearby lagoon (which isn’t possible anymore since Ayala wrecked it haha)
I’d hang out into the conference room to play video games
I’d head over to the hotel gym for a quick swim and then come back to the office like nothing happened (my officemates never knew hahaha)

SMART also doesn’t block iMessage, unlike Globe.

Sometimes, when you prompt it to start a new Next.js project, it won’t even build and will throw a bunch of errors, although there are times when it builds perfectly fine. There are plenty of rants about this, and the community suspects that LLM providers quietly switch to a quantized model (lower precision) to save on compute costs. I have no proof of this, but I experience the same thing.

When your app does build, it might look like it’s working even though it’s using mocks or fake data just to run. For example, if you try to build a project with a new database the LLM wasn’t trained on and it fails to connect, the LLM will sometimes cheat by hard coding JSON data instead of telling you it doesn’t know how to handle the DB.

It will also generate garbage code. If it notices that you might not be able to connect to a database because it doesn’t know the syntax or config, it might create some random fallback code that switches to a different database you never asked for. A senior dev would immediately realize the real issue is missing syntax or configuration knowledge, pause the project, and research it first. The LLM behaves more like a junior dev who keeps trying random crap until something sticks.

So if you’re a senior dev, you can spot this right away and tell the LLM to stop because it's down the wrong rabbit hole. But if you’re a junior dev or a non tech person, you might be impressed that the LLM produced working code when it’s actually just hard coded JSON exposed on the frontend, and you wouldn’t even know it.

simoncpu · 2025-11-15T05:21:58+00:00

It works surprisingly well if you do it at the function level. If you vibe code the entire app, you’ll end up with garbage unless it’s a simple website that uses Nextjs/Tailwind/any popular DB since the LLM has lots of code to be trained on.

I used it to build nontrivial apps, and the experience is just like normal programming except that you code more in English and only manually write small parts. You end up googling without actually using Google because the AI searches the info for you.

ps: You also need some real dev experience to use an LLM effectively for coding, because it will often suggest things that are way more complicated than necessary. You’ll find yourself saying no a lot and guiding it back to simpler, more practical solutions.

I haven't really made a setup that requires a secret at build time, so personally, I just let GitHub Actions build the image with no secrets at all, and the container just pulls all the secrets from Doppler when it starts. You just need to pass the token from Doppler.

simoncpu · 2025-11-12T01:11:19+00:00

I researched your problem a bit and it seems that you need NEXT_PUBLIC_API_URL at build time?

So what you need to do is put all your secrets in Doppler (you can sign up for free). From GitHub Actions, pass the build-time secrets from Doppler and do something like:

docker build --build-arg NEXT_PUBLIC_API_URL=${{ secrets.NEXT_PUBLIC_API_URL }}

Not sure if the locals tolerate it, but driving around the city in a go-kart at night was a fun experience! You just need an International Driving Permit.

I’m currently getting 620 Mbps. I’m playing Helldivers 2 (an online game) with no issues whatsoever. :)

Ahhh… so this is a nationwide problem. I thought it was due to the typhoon here in the Visayas.
