greenail··on I used Claude Code to get a second opinion on my MRI
you can set the "temperature" which is a lever on how stochastic the prediction is. If you are doing your own inference this is clear and easy. If you are consuming tokens this is outsourced.

maybe it doesn't turn them into assholes. maybe it just frees them to act naturally.
greenail··on AMD pulls a bait-and-switch on Linux users with Vivado licensing changes
if "the ai" was delivering value you'd think it would be lowering both cost to develop these dev tools as well as the cost to support them. In that light the move is odd unless they don't know how to use AI to lower those costs or it cant.
greenail··on If AI writes your code, why use Python?
maybe now isn't the time but at some point it needs to be better understood which models are best for which types of programming or styles or languages. These models are not all the same for every language. The harness is also a factor. Python seems to be somewhat an exception today but that may not last. Another question might be: is there a pattern where you prototype in language X and implement in language Y. The models seem to be very good at porting code. I've used this pattern with python -> c++ SDL to squeeze out performance after I had a working gui. Has anyone measured this in terms of speed (wall clock) and in terms of token efficiency?
greenail··on If AI writes your code, why use Python?
my experience with elixir is that if you tell the LLM "let it crash" it is productive. If you don't tell it this it hides errors and writes crappy tests. So, maybe it is go and not concurrency programming.
greenail··on Taking on CUDA with ROCm: 'One Step After Another'
I think GB10 is a bit of a counter point. There are tons of features that are not implemented for GB10 which was released 8/2025 It isn't all roses on the cuda side.
greenail··on Converting a $3.88 analog clock from Walmart into a ESP8266-based Wi-Fi clock
you can buy dual coaxial shaft steppers ( X40 ) for car instrument panels open them and remove the hard stops. A very small magnet and 2 hall sensors gets you end stops.
greenail··on How to sell if your user is not the buyer
This is a bit of a simplification of how enterprise sales works. A few extra dimensions are sometimes required. For "decision makers" their own personal view of reality may not in fact be accurate. You sometimes must vet that what they tell you (and may in fact believe) actually reflects the actual power dynamics of a big enterprise. There are extra dimensions to consider; The first is: are they in a cost center or are they generating revenue. The second is: are you trying to get new technology adopted or is this considered "standardized". The third is: who might perceive your product as a risk, or a threat to their power? These data points inform your sales strategy both in who you sell to, who you avoid, and when you might choose to engage a particular persona, when to go small and when to go big.

this doesn't add anything to the conversation.
greenail··on Scar tissues make relationships wear out (2013)
This doesn't work when you are in a relationship with someone with a personality disorder like BPD. They use it to hurt not to heal.
greenail··on Ask HN: Advice that changed your life?
It is not who you know, it is who knows you! Seems like a small nuance but realizing this changes how you think about building relationships.
greenail··on Signal is secure, as proven by hackers
+1: the globally unique identifier that is reused across multiple accounts is an antipattern in my opinion. This is just as bad as reusing passwords. There should be no need for anyone to have to reuse email user id's or phone numbers or credit card numbers. These should be unique per online "relationship", the way your CC chip creates per transaction identifiers. The fake account problem needs to be solved in another way. You simply can't take these GUIDs back once they are leaked and that leaves your only choice to burn them or just accept the risks of having that data leaked all over the net.
greenail··on How to Invest in China's Cloud
IaaS lockin should be minimal if you make the right investments in automation and think hard about dependencies you can't unwind quickly. An IaaS deployment without automation misses the point of cloud. The easy test is "can you turn it off and get it back on without manual effort?" If the answer is no you are likely locked in. This would also be true in a colo or datacenter. The biggest benefit to IaaS is that you can make changes with reduced risk. You move away from 3 year cycles and big upfront commitments in exchange for the ability to make big changes quickly. If you move to the cloud and don't get that benefit you have not gained the core value. If you don't need that benefit you may not need IaaS cloud.

I have seen many cloud moves that don't leverage autoscaling and I've been wondering why anyone bothered. Is this just an inability to justify investing in modernization? Is lift/shift first a good strategy, it seems to me you miss the opportunity to fix long term tech debt if you just move.

greenail··on One-on-ones with executives
if you flip the script you'd never ask an exec you don't know for a meeting without giving context. This is common courtesy if you do it without seeming demanding.

"Looking forward to our discussion. Can you give me a bit more context for the meeting and an agenda? This way I can be sure to have enough time to properly prepare. Thanks..."

would you say no to that?

greenail··on One-on-ones with executives
If you don't have a relationship with the executive you should ask for an agenda and clarity on the goal of the meeting. You should say "you need the context so that you can prepare and ensure a productive meeting". Even if there is a one or two sentence description you should ask for more info. This does two things, first it helps you prepare and 2nd if they don't provide an agenda you get some forewarning that something is going on. Worse case they say no, best case they see you habitually doing good prep work.
greenail··on A list of developer questions to ask prospective employers
This is a very good question, but you should also dig a few why's into it: "What type of people are successful here? What type of people are not?"

I also like to ask: "what's the best thing about working here? followed up with what's the worst thing about working here" You typically get some insight based on how open they are to the last question.

greenail··on A list of developer questions to ask prospective employers
My rule of thumb has been to stay close to the revenue so perhaps asking if you would be working on topline related projects or bottom line related project. Related is to ask what the top priorities are and to try to understand where your focus would be in relation to the top 3.

Are you basing this on math or history?

it is a good book actually!
greenail··on Put 3D Metal Printing Services to the Test, by Making a Watch
it doesn't look very good visually and also in terms of dimensional accuracy. how do you finish this without cnc or hand work? It looks warped. This lack of dimensional accuracy is a huge problem with additive processes IMHO. It would be fantastic if we could have 3d metal printers in our garages. It would open up a ton of possibilities.
greenail··on FedNow FAQ
If you are not a fan of big government do you view expanding the power of the federal reserve as dangerous?
greenail··on Influencing Large Change with Little to No Authority
step 1: make sure you boss's goals are aligned with yours step 2: make sure you boss will have your back and clearly communicates how aggressive they expect you to be. step 3: have goals that focus on topline revenue not bottom line cost/risk step 4: ensure your performance evaluation doesn't become political

if you can't get steps 1..4 find another job.

crypto is a solution in search of a problem which makes me wonder how these startups are getting funded.
greenail··on The White House and Twitter Censorship
"they had seen data viz that had showed he was the epicenter of disinfo that radiated outwards to the persuadable public." Interesting they are plotting social graphs like this in the whitehouse. I wonder what tools they use.

greenail··on Tell HN: After 10 years of experiments, custom username emails receive no spam
The problem is not bad intentions or selling your information.

The problem is that they copy it into a DB and it is a globally unique identifier. Once this happens you have lost control. You can never ungive that GUID. Your only recourse becomes spam filtering or migrating to another email GUID and waiting until the new one gets leaked all over the intarwebs and then doing it again. Phone numbers are even worse.

The solution is fairly simple, as discovered by the OP. Don't give out the same GUIDs when you sign up for an online "relationship".

It is a shame this pattern exists, people should stop designing accounts like this.

greenail··on Ask HN: Have you ever switched cloud?
What is the difference in expense between the "loads more" you are spending and hiring and managing a sysadmin? Ballpark is fine, interested to know if it is 1x,10x, 50x?

greenail··on Using Windows after 15 years on Linux
I just realized I've been using windows for 30 years... wow!

The main problem here is that this is a work machine. Generally you can't do what ever you want on those. I imagine Linux is harder to lock down in a corp environment and the complaints are rooted in that notion. WSL fixes many issues, I don't think I'd be spending much time in power shell if I had the option to use WSL.
