Anak Krakatau: Volcano eruption closes six Indonesian airports

James Gosling, creator of Java, asked by Navin Reddy whether he codes with AI (somewhat cleaned up from the transcript):

"NR And do you use AI to do that?

JG: I have played with AI tools and I mostly find them to be really annoying. I mean, the thing is that I know how to write software. Um, and every time I've used an AI tool, I I look at the software that it generates and for the most part it's just awful. And I care about how evolvable a piece of software is, how reliable it is, you know, how testable it is. And I have yet to find a coding system that works for me cuz it just all you know it all feels like a really great demo, just not ready for prime time.

NR: So do you think there will be a day when AI can reach there?

JG: Oh maybe, kind of, but why? I mean you know in the spectrum of
problems in the so in software engineering, coding has never really been a big problem. The places where there are problems are in like testing. How do you know that this piece of software actually does what you need it to do? That's a really really difficult
problem. That's a problem that is unpleasant. It burns a lot of a lot of time. And you you know, everything I've seen about AI tools just is that they just make hard problem worse. And the the easy problem, yeah, marginally better. But also the easy problem is also the enjoyable problem. So I view AI in part as stealing the fun and making the torture worse. And you know, people go, "Well, you
know, I wrote up this little Swift iPhone app. Doesn't that count?" And it's like, "I don't care, right? I mean, small toy apps like that are are nothing. I mean, I'm, you know, software doesn't get interesting until it's got like until it's like millions of lines, right? You know, until you're doing something like, you know, operating FedEx, right? Right. You know, and you know, some, you know, a place like FedEx, you know, they've got hundreds of thousands of llines of code, probably actually probably millions of lines of code and, you know, 100 000 engineers. I mean, it's a really complicated thing to run a business like Uber or FedEx or UPS or a bank. And building software suites like that
is is where there's difficulty, you know, glossing up, you know, a Swift app to take a survey. Okay, that's fine. But that's not a problem.

NR: That's right. So when you're building a give it business where you have as you mentioned million lines of code and then we have entire team I mean teams of team who is working together to get the one thing that's where it excels

JG: where what excels?

NR: the human

JG: oh yeah I mean when when it when things get complicated you need people. I have not seen a scrap of evidence that the AI coding tools, you know, if if you wanted to build the
next FedEx and you were just going to vibe code the next FedEx, I think you'd be in trouble.

NR: Yeah. Yeah. You never know when you have security flaw and getting hacked.

JG: Yeah. Yeah. O when when your AI tools decide, you know, the best way to be profitable is to steal money from all
your customers. Because you know then people have tried to to to do
experiments like have AI just run a
single vending machine as a business
or do security penetration experiments
inside inside a company and then you
discover that all hell breaks loose, right? Um these these things are a very,
very long way from being deployable at scale with a decent amount of faith that things will work out."

Operaton users: in 2027 I'll be back at conferences and user groups to talk about the project — and for user groups I'd love to share the stage with you.

I'll cover governance, internals, what a process engine is even for. You have the interesting part: migrations, the processes you actually run on it.

No polished talk needed, 15 minutes is plenty, and we can keep the client anonymous. If there's a Java user group near you, I'll approach them together with you.

Reply or DM.

I like trying different programming languages. For fun, I benchmarked some of them (#commonlisp, #java, #lua, #picolisp) on a simple n-queen task.

This is the [repo](https://tangled.org/argo-net.bsky.social/some-pl-benchmarks-1) and this is the [analysis of results](https://argo-net.tngl.io/some-pl-benchmarks-1/).

C is the fastest; SBCL is rock solid at 2X C speed; Java starts slow but it reaches C when the problem size increase.

AI-native Tiny Teams — правильный вектор или хайп 2026 года?

В 2026 году из каждого утюга звучит тезис: несколько сильных инженеров с агентами теперь способны делать работу, для которой раньше требовалась полноценная продуктовая команда. Его подогревают прогнозы Сэма Альтмана о «единороге из одного человека» , заголовки о tiny-team moment Кремниевой долины и истории вроде Lovable: $100 млн ARR за восемь месяцев при 45 сотрудниках . В такой подаче tiny team выглядит чуть ли не как будущее разработки и почти панацея. В этом есть частичка правды. AI ускоряет исследование, прототипирование, написание кода, тестов и документации. Полевые исследования фиксируют рост производительности разработчиков , а CircleCI в State of Software Delivery 2026 показывает существенный рост throughput у наиболее эффективных команд.

Java security updates are getting a second track. Alongside the usual quarterly CPUs (Jan/Apr/Jul/Oct), Oracle is introducing CSPUs: irregular, sometimes-monthly patches for urgent vulnerabilities. First one: August 18, 2026.

Why? AI has compressed the time between a vulnerability being found and being exploited, making the old 90-day wait riskier.

Read this blog by @frankdelporte on what to adjust in your patch-monitoring and pipeline:

Java deprecates support for macOS x86

Apple has transitioned its hardware products to the AArch64 processor architecture and is phasing out support for x64. Oracle engineers will thus stop maintaining the macOS/x64 port as of JDK 27. Maintaining the port is a significant burden.

Years ago, I migrated from #NetBeans to #IntelliJ.

With all the AI and telemetry and terms of service and free trials and whatnot, I'm starting to think it's time to migrate back…

My only major reservation is that https://jte.gg has only an IntelliJ plugin. I will have no completion, highlighting, etc in my HTML templates any more, and some of them are rather complicated…

What does everyone think?

Event-Driven Architecture isn't always the answer. Vincent Vauban explains when EDA might not be the right choice for your project and what alternatives to consider instead.
