Apple is struggling with making Apple Intelligence super useful. Why? Because of their OS privacy and security first policy. They need to balance between being less secure and making their systems more AI-driven or sticking to their old values and not competing in an AI race.

Searching through a tree doesn’t need to be O(n) in terms of the time complexity. It can be O(log n) if some conditions are met. damianmarkowski.com/2025/04/06/b...

A queue data structure gives us a possibility to efficiently (O(1) time complexity) add items to one side of a list and remove them from another one. What if we wanted to be able to add and remove them from both sides? The answer is: deque damianmarkowski.com/2025/03/23/d....

The Time Zone Database data was updated yesterday. Let’s remember that a timezone list changes several times a year, it’s not constant. www.iana.org/time-zones

I started watching Adolescence on @netflix.com and it made me think of one potentially very useful use case for AI - police reports. They have body cams, they could have mics too and some AI tool could be preparing the reports from their interventions. A lot less paperwork for them.

It's much easier and fairer to be data-driven rather than opinion-driven. People may have different opinions and data is the same for everyone looking at that.

Cursor (www.cursor.com) and Figma MCP server (github.com/GLips/Figma-...) are the first dev support AI tools that work nicely for me. I think Cursor Pro will be my only AI related subscription that I will keep paying for, at least for the upcoming few months.

So almost all of us know those AI models and chats that learn our digital life but there is for example www.bee.computer that learns our non-digital life and then is able to answer questions related to our real, in person life.

"Today, more than a quarter of all new code at Google is generated by AI, then reviewed and accepted by engineers." from blog.google/inside-googl... is kinda eye-opening for me. Writing an iOS code will become obsolete in the future so I decided to start learning Python.

Some people say that time is the most valuable asset we may have. Let’s say you are not talented, have no useful skills, have no job but thanks to that a lot of free time. Are you in a good position then? I wouldn’t say so.

You move forward as a team. It doesn’t matter much which individual contributor implements what. Let’s remember that we build stuff for our users and they don’t know nor care if a given feature was developed by a dev A or dev B.

It's a bit harder to find a Keychain Access app in macOS Sequoia than it used to be in the previous macOS versions. Apple moved it from "/Users/<current-user>/Applications/" to "/System/Library/CoreServices/Applications/".

We shouldn’t need to use any passwords or tokens or anything that we may easily lose or forget to log into the digital products or services. We shouldn’t need to use any devices to make payments neither. They understand it well at Tencent and they developed the Palm Scan Payments system.

One of the problems with a democracy is that it’s hard to plan and execute long term goals in a democratic country. A president and government change every 4/5/6 years. They usually come with their own priorities and goals and that really doesn’t help with building something long term.

Instagram added an option to schedule a message. That’s really cool! I like calling myself as a “time zone agnostic” person, meaning that I do things regardless of the time but I know that most people are not like that and for example they don’t like getting messages at 2 am their time.
