@MrPeterLMorris Yeah lol, would not write code like either of them in a real system.

Very good, very impressive. Now let's see a boolean expression parser.

[Peter Morris @MrPeterLMorris]

I leave this source code, without comment, for your attention.

#Clojure vs #CSharp

@MrPeterLMorris Can probably get away with parenthesis cast and FQN import

static bool Parse(string s) => (bool)new https://t.co/T0Dvv6dRkQ.DataTable().Compute(s, "");

@MrPeterLMorris Or if you want to make use of the fact you are in a JVM. Supports the full syntax of the above version.

If you want to change the rules to use &&, || and !, you can remove the .replace lines.

@MrPeterLMorris Version for closure with a real version and a cheap trick version

They are doing this to attract people who want to use AI for scripting. Visual scripting and AI are not a good combination.

They are banking on the people who will use AI for scripting and become new customers will outweigh the number of existing customers that they will lose.

Epic has always chased the asset flippers, even before AI. Advertising better graphics, free megascans, getting big devs to switch over to their engine by waiving the fees etc.

@WarrenInTheBuff Mine is much worse over the last few days with Fable, Mythos and GLM-5.2 slop engagement bait. Serves as a good mute filter though

1.5 years later and software engineering still exists

[null @nullpointered]

If you are a software engineer who’s three years into your career: quit now. there is not a single job in CS anymore. it's over. this field won't exist in 1.5 years.

@herrcore You have heard about script kiddies, now get ready for slop kiddies

- Hacker steals Claude agent
- Hacker uses Claude to hack
- Hacker pivots to compromised server
- Hacker uploads Claude (with logs) to server???
- We investigate compromised server
- Full agent logs detailing hacking recovered 😅

AI agentic hacking deep dive: 50 servers, 14 companies, all the prompts, tools, attribution...

There is a growing trend in the data space to use LLMs for every problem. In 99% of cases this is a bad choice.

Don't use a sledgehammer when tweezers will do.

@satya164 @jamonholmgren This is probably my #1 pet peeve rn

I hate how long-ass PR descriptions became a thing with AI, bro just put the code in the bag.

@rfleury @mitchellh @wagslane For UI/UX (and games), getting a user to use your app/play your game while you silently watch is 100x more valuable than trying to dream up BS metrics.

There is a problem space where unit testing is the right choice, for example I would argue a standard library be tested with unit tests, but in the vast majority of cases I would agree.

Unit testing is just another tool in the toolbox. Sometimes it is the right choice, sometimes it is the worst choice possible.

Unit tests suck at testing interactions.

If you have a large deterministic system a snapshot test is the answer. If you have a non-deterministic problem space precision/recall/f1 (or sort of loss function) is preferable.

Property based testing is also sometimes the right answer. For example if you are testing an encryption implementation you will get way more mileage out of running : decrypt(encrypt(x)) == x 10k times on random x's than encrypt(x) == "random_cipertext".

There is so much more nuance than unit testing = bad

The demo for Order of the Sinking Star, the *huge* puzzle game we've been working on for a long time, is free this week on Steam...

Playable only during NextFest, it'll be gone after this week, so check it out if you're interested!

If you miss fable you are part of the problem

Working hard through the weekend on the demo for Monday!
