That's a wild statement to me. Even with spending significant time making plans with Opus 4.7 and GPT 5.5 on xhigh, I still find lots of poor decisions made when it actually goes to implement it. I find the quality of PRs hasn't dramatically changed either way because the better engineers will spot the issues whereas others will find what the AI is doing acceptable.

I'm having this exact conversation with senior leadership in my team. I'm looking forward to it and I might do a book club reading when it comes out!

I just started using OpenWrt on Incus via LXC and it works really well. The most difficult part was just learning the config file. It looks like upgrading OpenWrt (esp. on LXC) is the tricky part though so not looking forward to that. I considered moving it to a VM so upgrading it is easier but it runs so smooth on Incus.

I read the first part and I enjoyed it. I agree that us developers aren't great at communicating tech debt effectively. Managers are also not great at prioritizing it. I think the "debt" analogy has been a net negative as management often thinks "we'll just pay it later" but don't often see how much pain it's causing. So having a resource to help both sides on this topic is very valuable.

New comment by giulianob in "Ask HN: Do your eyes bug you even though your prescription is "correct"?"

giulianob — Sat, 08 Mar 2025 00:05:05 +0000

I just recently got sclerals for dry eyes and I'm still going through the adjustment process. Usually they are prescribed for keratoconus (misshaped cornea) and not something most people need. The doctor actually said it's more challenging putting it on someone without keratoconus (like me) because I am used to having fairly good vision with my glasses and sclerals aren't as easy to get right as glasses/normal contacts. They have been amazing for dry eyes so far though.

You mean `dotnet publish -r linux-x64 --self-contained` ? This will embed the runtime in the executable. You can also do trimming so it removes anything that's not used. Also, there's AOT but it's got a ways to go.

They recently updated it with an official vendor for a [PCB kit](https://www.peakcoffee.cc/product/gaggiuino-v3-kit-set-gaggi...) that (I believe) includes all of the internal components needed. I did the lego build w/ tons of soldering and ordering parts off Aliexpress. This new kit should make it much easier for newcomers. You still need to know what you're doing and it's not for everyone. A machine with similar capabilities is something like the Decent at $4k.

Wat... "Like" implies preference. You're using the word "story" to imply someone pulled it out of their imagination. What they said was "we currently have no plausible theories that doesn't require dark matter". These theories have to be consistent with other theories and observations.

New comment by giulianob in "Ask HN: Current state of coding .NET code on non-Windows machines?"

giulianob — Thu, 26 May 2022 17:39:53 +0000

I have coded on .NET in Windows/Mac/Linux. It works equally well in all environments. You can use VSCode, VS for Mac, or Rider. I use Rider in all platforms. It's an awesome IDE.

Source: I work at MS but have used .NET on other platforms at previous jobs.

New comment by giulianob in "Milk alternatives produce up to 4.5x less greenhouse gas emissions as milk"

giulianob — Fri, 29 Apr 2022 17:30:57 +0000

Actually we haven't evolved to digest milk after childhood that well:

    While most infants can digest lactose, many people begin to develop lactose malabsorption—a reduced ability to digest lactose—after infancy. Experts estimate that about 68 percent of the world’s population has lactose malabsorption.1
    Lactose malabsorption is more common in some parts of the world than in others. In Africa and Asia, most people have lactose malabsorption. In some regions, such as northern Europe, many people carry a gene that allows them to digest lactose after infancy, and lactose malabsorption is less common.1,2 In the United States, about 36 percent of people have lactose malabsorption.1
    While lactose malabsorption causes lactose intolerance, not all people with lactose malabsorption have lactose intolerance.

Points are flawed. Whether you have them grow linear, exponentially, or fibonacci doesn't make a difference. The fundamentals are flawed. They cover it in their videos and in more depth their talks/books.

Estimating a single task is only really important to keep your cycle time in check and have the conversation about "should this task be broken down?"

Estimations from engineers shouldn't be used to forecast when a feature will really be done. That's where the model comes in and probabilities comes in.

giulianob — Thu, 04 Mar 2021 18:49:55 +0000

Definitely my biggest gripe is story points + estimations. It's just completely flawed. We should be thinking more probabilistic (i.e. there's an 80% chance we'll get this done in 2 weeks). We should be doing that by running actual models on past work rather than gut feelings.

Manufactured? you should really read the Mueller report and see that there was plenty of wrongdoing. Saying it was manufactured is pretending like all of the evidence, meetings, etc... didn't happen.

giulianob — Wed, 04 Nov 2020 15:10:12 +0000

I've worked professionally on C# and Go. I've seen overly abstracted C# code but I also have seen Go code that was clearly missing good patterns and ended up a ton of spaghetti. The difference that I see is that C# gives you the tools to do it well whereas Go lacks many tools to make a complex code base nearly as maintainable as C#.

giulianob — Thu, 24 Sep 2020 03:38:14 +0000

I've been using the opentelemetry package for C# to push tracing data to Honeycomb and it's really good. It takes a bit of learning but it's extremely powerful. Once you're over the hump it's very easy to quickly add new telemetry and its night and day difference to typical logs/metrics.

C# has gone completely open source and cross platform. .NET core was essentially a huge modernization of the entire runtime and ecosystem. It's becoming one of the most performant managed languages according to Techempower benchmarks.

You can also see just how much it's improving in some areas and the level of detail they're paying to it: https://devblogs.microsoft.com/dotnet/performance-improvemen...

Wow I'm surprised people are so eager to go back to the office and completely aren't valuing the potential freedom of being able to live where they'd like rather than where their work happens to be.

New comment by giulianob in "HotSpot compiler: Stack allocation prototype for C2"

giulianob — Thu, 02 Jul 2020 12:55:13 +0000

I'd say ref structs are more explicitly stack allocated since they're not allowed to be boxed. Stackalloc is used to allocate arrays on the stack (or rather a block of memory).

To be fair this is what Electron does too via the browsers. It's just doing it via the worse possible way by leveraging technology that's awful for building UIs. I'm a fan of flutter they're definitely onto something. I hope they can bring it to the desktop in a way that works well too.
