@JavaDataPro @sivalabs Instead of String, why not use java.math.BigInteger as the type in Java, and only serialize it as string?

@sivalabs If your number has more than 16 digits, JSON or JavaScript will represent it as a floating-point number (double), and you may lose precision. To preserve the exact value, you should send it as a string: @JsonProperty("bigNumber") private String bigNumber = "792574275907102180";

TIL: JSON Number Precision Loss From Spring Boot API I am returning a field value 792574275907102180, but in the JSON response its value is being shown as 792574275907102200. Why? chatgpt.com/share/694f4ae3…

@DailyUrgencias @johnrushx Maybe in his mind AI = LLM?

@johnrushx You are wrong, most doctors use it everyday in ultrasound, ct scans, research, ekgs, hospital data, presentations and more

I haven’t seen any doctors using AI, Construction workers don’t use it either, Teachers barely heard about it, The difference between a human & human+ai is so huge that it should be illegal to not use AI at work. It hurts to see almost no AI adoption outside of the tech world

@HSVSphere @FallenOne58035 In any project there is always room to improve. But it doesn’t mean that the people’s “improvements” would actually make the project any better. They might, but it’s definitely not a certainty.

@FallenOne58035 No, my point is there is room to improve and people are pushing for that. I use Linux full time and I want it to improve.

People are finally realizing how low quality the Linux kernel code is and I'm all for it. Wake up from your fantasy

@iamsaquibdev The java.net package in 1997 😉

What's your favorite Java feature that made you wonder how you lived without it? For me It was introduction of Record Classes.

@ducmite @Indy259 @ras_twit2K @parkerworth I understand the inconvenience but I bet most of the people don’t read their receipts and understand how high the tax rate is. Displaying tax-free prices and adding taxes at checkout provides a clear perspective on the tax rate.

@raehalme @Indy259 @ras_twit2K @parkerworth For example food is taxed lower, 14%. I much rather see the final price than estimate on the price tag. I don’t need to know what tax-% bracket each item in my cart belongs to.

I'm American. I just revisited my home country after moving abroad 2 years ago. What I saw shocked me. 13 American oddities I still can't believe:

@Indy259 @ras_twit2K @parkerworth That would be extra activity you need to do. I understand the inconvenience with tax free price tags, but it makes the amount of taxes you pay much more explicit. But we can agree to disagree on this one 😉

@raehalme @ras_twit2K @parkerworth I've yet to see a benefit of a price tag that does not show what you pay at the checkout. The "you see the tax" argument is debunked (you see that on the receipt).

@Indy259 @ras_twit2K @parkerworth Sure, you see the tax on the receipt both in Europe and in the US. But we’re talking about price tags. In Europe it’s the price you pay. In the US you get to add taxes, tip and whatnot.

@raehalme @ras_twit2K @parkerworth You see the tax cost on the reciept in Europe. Do you see the tax cost on the price tag?

@Indy259 @ras_twit2K @parkerworth In Europe you explicitly see what you must pay. You don’t see the tax cost. I’m pretty certain that most Finns, for example, with 25,5% VAT do not realize how big part of the price tag is the taxes. Because if this reason I favor the American price tags.

@ras_twit2K @parkerworth It's on the price tag? You explicitly see the tax cost on your receipt here in Europe. At least I know how much comes out of my pocket for the €20 basket of goods I have. How much will the basket of goods with a tag price of $20 cost you?

Collection of insane and fun facts about SQLite. Let's go! SQLite is the most deployed and most used database. There are over one trillion (1000000000000 or a million million) SQLite databases in active use. It is maintained by three people. They don't allow outside contributions.

@analyticsaurabh @frankcdale @kyleplacy @clairevo Or cannot verify whether the output is good or not. Even with a good prompt the first response might not be what you really (should) want.

@frankcdale @kyleplacy @clairevo AI gen code takes a lot of wrong turns. One need experience to guide it to right task. Put another way, most don’t know what they should be asking for.

Not enough CTOs are talking about how they are practically putting AI codgen and agents into their existing large teams of SWEs: tools, training, and culture. Here’s a few things we’re doing: - ripping down everyone’s egos about what can and can’t be done by whom (ai or human) - allocating budget to experiments - getting legal, infosec, and ops simplified and aligned early - focused slack channel to share wins, fails, and asks - 1 motivated sponsor per tool - use it or lose it access - calling on peers for use cases and learning - ai transparency (no one pretends they’re not using a tool to do work) What’s working: - ChatGPT in non tech functions - v0 for prototyping - cursor in pockets - copilot in pockets - chatPRD for engineers What’s not - 8 million rogue meeting note takers - think we’re underusing perplexity - no formal l&d - only a few pushing novel thinking - minimal automations & agent work

This! 💯There’s usually no need to actually see the password. Just copy it to be pasted to a password field.

@simas_ch I think Java’s API for json was worse.

JPA Criteria API is the worst API I know 🤬

@colablizzard @GergelyOrosz @Pragmatic_Eng To get the boost in productivity you must be competent enough to understand and evaluate the output, whether it does what’s asked for or doesn’t.

@GergelyOrosz @Pragmatic_Eng + and when it came to me for debugging, I straight away opened Postgres Doc and read two pages and the solution was literally in their example (one line) vs the AI generated mess.

A very unexpected finding as I am going through responses to the software engineering AI tooling survey (to be published in @Pragmatic_Eng:) The overwhelming majority calling LLM coding tools “overhyped” do not use them! (As in they are devs, but refuse to use them.)

@copyjosh @tri_rizeki @housecor That would be confusing as you could add all such parameters to the same URL. Maybe instead you could specify parameters action and id, then there would be no confusion.

@tri_rizeki @housecor Not really any different? could have separate parameters to listen for, ie editUserId= and viewUserId=, and ?addUser=true

Scenario: A modal for editing a user. Modal URL: ?editUserId=1&openEditUserModal=true Problem: The openEditUserModal param is needless. Solution: Derive. If editUserId is in the URL, open the modal. If editUserId isn't in the URL, close the modal. Benefits: ✅ Eliminates needless state ✅ Avoids a potential params out-of-sync issue. If openEditUserModal is true, but editUserId is missing, that's a bug. Summary: Avoid redundant state. Derive.

finally ready to announce that my git zine, “How Git Works", is coming out in ONE WEEK! on May 31! it also comes with this (free!) cheat sheet which you can download and print out here: wizardzines.com/git-cheat-shee…

@simas_ch @royvanrijn Agreed, but you can still argue whether the blade part is up or down 😂

@royvanrijn That's why we always buy Miele dishwashers 😉

Let’s settle this once and for all: Knifes go in with blade up or down? 🔪

So true.

@lemire @WoundedEdgeboy @Jonathan_Blow You really shouldn’t push anything as a cult.

@WoundedEdgeboy @Jonathan_Blow To be fair, I still teach Java today, with all the OOP things… because you kind of have to know if you want to claim to be college educated. I just don’t push it as a cult.

It is hard to overstate how strong the push for object-oriented programming was. It even bled out into other fields like education (look up "learning objects"). You had to organize your programming projects into hierarchical classes and you would be ridiculed if you did not. Java and C# are a reflection of this era. It took 25 years for the obsession to die down. Basically, the gurus had to be given time to retire. Object-oriented programming can work… but there are serious pitfalls that will make your projects harder to maintain and optimize. Deep inheritance is almost always a disaster. The lesson is: don’t blindly embrace the latest things even if everyone is. Masses will lead you astray. Be critical.

@sevenseacat @adamhjk @joshprice And even if you were ops-y enough you probably have better things to do than managing your CI/CD workers.

@adamhjk @joshprice It’s a very different beast - GitHub Actions is great for someone like me that is not particularly ops-y. I don’t want to have to manage clusters of agents and workers and etc. I want to write a yaml file and watch my builds get run.

I feel like GitHub actions showed real promise to grow into something spectacular. Instead it’s kind of languished. Watching the SI team convert to buildkite, and it’s shocking how much better it is.
