I'm in the process of relocating to UK, and I'm appalled by how difficult it is to open a bank account as a newcomer.

I tried to open an account before coming here, it didn't work. Then I relocated, and everyone requires utility bills as a proof of address, but I don't have bills yet!

What's actually scary is the number of people in the comments who believe LLMs are lying on purpose.

IT'S A COMPUTER PROGRAM THAT GENERATES TEXT. It does not have an identity, it just spits out the most fitting response based on what it learned from the internet and the books.

I don't think vibe coding is like working with a junior dev... unless the junior dev has attention span of a puppy and memory of a goldfish

Ugh, coding with AI is sometimes wild. I've been trying to rename 20 files, update class names and fix imports with Cursor for like 15 minutes. Every single time it starts modifying other things that I told it specifically not to do

I’m listening to some 2010s hip-hop playlist and I’ve just realized some of these songs are almost 15 years old and I used to listen to them when I was a university student 😫

Got kicked out of religion class for questioning the resurrection 😅

So in Poland we have religion classes and one day my teacher was "debunking" myths about resurrection. One of the myths was that Jesus didn't die when crucified, but just fainted...

I can't with Reddit's algorithm. I clicked on one post by accident, now half of my main page consists of mold pictures and Reddit sugests me communities like "mold" or "moldly interesting" 🤦🏻‍♂️

People often wonder why we haven't seen extraterrestial life yet here on earth.

Looking at humanity right now I think I know the answer: civilizations eventually just destroy themselves form the inside.

Climate change, the biggest threat humanity has seen, is not enough to unite us.

What's the point of AI assistant on Quora? If I wanted to get a ChatGPT-like response I'd just open ChatGPT. I opened Quora because I expected answers from actual, living human beings, not a bot

Sigh, it's just impossible to avoid the news today 😕 so I'm trying to focus on creating the "presentation slides" game. Here's my progress after ~3-4h of work:
January 21, 2025 at 2:02 PM
I'm actually doing it. I'm working on the content of the presentation and at the same time I started working on assets for the game. I created the first map and today I'm going to load it and let the character move around
I have this crazy idea to build a simple game to use as presentation slides, instead of Powerpoint/Keynote slides. The problem is: I have 0 idea how to build games, so I'm going to try to use LLMs to build it. Let's see if I can make it

LLMs might be the thing that finally makes me switch from Neovim to VSCode. Neovim is fantastic for navigating code, but now I spend more time in chat window and the Copilot-like plugins are simply more polished in VSCode

Interesting observation when coding with copilot – when the initial solution doesn't work, it's often easier for me to fix it manually. When I ask copilot to fix it, it tends to generate incorrect solution and with each iteration the code becomes more complex while still incorrect

Today at work I wrote a small feature (~120LoC) using almost entirely AI – it generated some 95% of the code for me, I had to ask it to fix a few issues, we failed to write one unit test, but as someone who sucks at Java I was excited to complete this work in 1h

I'm attending a course on the Maven platform, and I love the content, but they could use some tech improvements, especially around the video player 😩

Booking flights is literally the most stressful part of any travel for me. Choose wrong date? Typo in the name? The change fee is so high it’s cheaper to buy a new ticket. Not to mention all the upselling. Can’t imagine how it can be considered a model experience to learn from 🤦
A pal with a Politico subscription has shown me the "early access" version of the AI Action Plan. No spoilers from me on the contents of the plan, but a quick 🧵 on a paragraph from the PM's introduction, which I suspect is ultimately more important.

Public services should be like booking flights.

Alternatively: despite being 40 years old, playing in an average team, and having a rather average season, LeBron is still #5 in All-Star voting. I know he's been #1 for ages, but he can be still top #2 in the west and #4 overall
Crazy how low LeBron is in All-Star voting. He's been #1 in voting in the West for 6 straight years and now isn't even on pace to start.

The Lakers IG has lost followers since the start of the season as well, first time that's ever happened.

What did we do with the web🤦

I wanted to see NBA All-Star voting results, so I googled it.

The link to nba.com opened the NBA app, but the actual article was a web view within the app. But wait, the results were in a tweet in the article, that opened in an in-app browser 🤦

My parents took their first flight in their mid-50s when I took them on vacation.
I took my first flight at age of 21
Today my daughter flies for the first time. She’s 6 months old

Happy about the dyno, I can repeat it quite easily now. Messed up the rest when recording, but eventually made it.

Good session today, did 2 new 6b+ routes, hope to do 6c within the next 2-3 months

I finished reading "Cinema Speculation" by Quentin Tarantino. It's hard to rate this book, I liked it, but I'm sure someone who watched all the movies Tarantino talks about would enjoy it much more.

I'm adding some new functionality to an app. The code is quite messy and lacks unit tests, so I'm using Cody to clean it up first.

Initially it failed to write any useful unit tests. Then I wrote one that worked and asked it to repeat it with various values passed as Paramus. That kind of worked...

I finished reading "Looking at Pictures". It's a decent introduction to understanding art. Unfortunately it focuses a lot on the themes, while analysis and technical chapters are too short for my taste. In the end solid 3/5 stars

I don't fully understandall the details, but it's indeed very creative.

What I get is that branch name was put in shell command without escaping it, so someone called their branch $(some commands) where the commands downloaded and started a crypto miner 🤯
absolutely incredible attack vector
