CobaltFire··on The Commodore Callback 8020 smart flip phone
My favorite phone of all time was my Nokia N9.

I would absolutely have another if there was an updated one.

CobaltFire··on Why has the pointe shoe been so resistant to change?
Skiing is another one like climbing. Its only recently where higher volumes and wider forefoots are available, and they still try to tell you to go a size down.
CobaltFire··on 10Gb/s Ethernet: switching to a Broadcom SFP+ module
Finishing up the same thing. 2x OS2 pairs with 2x CAT-6A to each drop, all coming together to the network closet.

Gives me fiber for bandwidth and copper for PoE. Figured it was smarter to do both than compromise to either one, and surprisingly the fiber was cheaper than the copper to pull.

CobaltFire··on My first ever game – a Godot arcade game with zero asset files
Played it a bit on iOS. Great job!

Love the constraint you gave yourself with the zero asset files. Would love to see how you went about doing that.

CobaltFire··on FPS.cob: A first person shooter in COBOL
That just gave me flashbacks. I wrote code on some ancient stuff that operated like you describe InterComm. Haven't done that in years, and I don't think much of anyone uses those systems anymore (Harris H100).
CobaltFire··on Why your asthma inhaler is so expensive (in the US)
We've been dealing with this exact issue with Flovent for my son.

Amusingly our insurance's captive/preferred pharmacy wants to mail us the generic for $40 + 25 S+H instead of us buying it locally for $150. Except that they can't climate control the shipment and it's 20F over the rated temp of the inhaler here today, in the shade. So their in house pharmacist allowed an override.

Still a royal PITA.

CobaltFire··on Ask HN: What is the AI setup for an experienced dev starting on a new project?
Thanks for that. Thats what I thought, but havent implemented.
CobaltFire··on Ask HN: What is the AI setup for an experienced dev starting on a new project?
This is where I show my ignorance.

I'm coming to modern software development late. My experience was in things which were in the mini-computer and COBOL genre of machines, or on things that were so tightly controlled that the review process for one change could take a year (combat aircraft and drones).

So CI/CD is something I'm actually trying to grasp because it feels so alien to me.

All that to say: Don't currently have any.

CobaltFire··on Ask HN: What is the AI setup for an experienced dev starting on a new project?
Very interested in the answers, as I'm in a similar situation.

Cofounder is using agents, I'm directly interacting with Claude and Codex. Self hosted forgejo due to Github issues.

CobaltFire··on Making peace with your unlived dreams (2023)
If you want to chat I'd be happy to reach out (I see the email in your profile).

I'm trying my hand at a startup right now, just to see if I can make a go of it.

CobaltFire··on Making peace with your unlived dreams (2023)
I read the article and fight with this from a different angle.

My son was diagnosed with cancer at 3, then during chemo it became abundantly clear that he had far more severe autism than we originally thought. Could have been made worse by the chemo and trauma; no real way to know.

Now my wife and I have had to give up all the dreams we had for when I retired from the military. A few good moves means that I actually retired at 40, though more modestly than I planned. But we will forever be taking care of him.

So we struggle with the unlived dreams often.

CobaltFire··on Show HN: Best setup local LLM found for a 5090 (llama.cpp fork + turboquant)
Given the hedges made in your statement here and the extremely questionable choice to trade a Q4 model with a less quantized cache for a Q6 with a Q3 cache I think this can safely be said to not fit the title.

The Qwen3.6-35B model has, in my testing, been decent but not nearly as good as the Qwen3.6-27B. Running that with a less quantized cache is going to be "better" for anyone using it for software dev in my limited testing.

CobaltFire··on The intracies of modern camera lens repair (2024)
That one I'm aware of. I used to own one!
CobaltFire··on DoD Officially Drops 180 Faiths from Military's Recognized Religion List
Had to look Wagyl up. Thanks for teaching me something new!
CobaltFire··on The intracies of modern camera lens repair (2024)
Didn't realize this, thanks!
CobaltFire··on The intracies of modern camera lens repair (2024)
I shoot the m43 system (have since the GH2, then E-M5, E-M1, and now a G9 II) and didn't realize this.

I only have one lens tight now (I tend to stay small on my system but this is a low point) but I'll keep it in mind.

Thanks for the info!

CobaltFire··on The intracies of modern camera lens repair (2024)
Because third party lenses cannot leverage the camera body to update.

Sigma has a dock that allows updates to their lenses in this fashion however.

CobaltFire··on Ask HN: How did you discover Hacker News?
Coworker about 10 years ago. Took me a few years to register an account.
CobaltFire··on I'm skeptical about efforts to revolutionize schooling
I can believe this. I had some subjects I was able to do this for going through Naval Nuclear Power school, and later college. Others I was unable to do this with.

Different people grasp things at different rates.

CobaltFire··on I'm skeptical about efforts to revolutionize schooling
I was taught (when teaching for the military, actually) that leadership/teaching/etc. often talk about toolboxes but neglect a VERY important one.

You shouldn't just have a toolbox of things you've picked up from your best examples, that you've been taught, etc. It's possibly more important to have another toolbox of broken tools from all the terrible bosses, reactions to situations you've witnessed, etc.

This way when you go to do something and it's not in your toolbox, you can pull out that box of broken/bad tools and see if it's there. Otherwise we perpetuate bad leadership (and teaching IS leadership) through intentional ignorance (forgetting the lessons those bad situations gave us).

CobaltFire··on Learn SQL Once, Use It for 30 Years
I ran across https://use-the-index-luke.com organically while learning SWL recently and I've been really enjoying it.

I can't vouch for it from any perspective except as an SQL neophyte but for me it has been teaching me a lot.

CobaltFire··on Learn SQL Once, Use It for 30 Years
I'm actually learning SQL now and finding it HIGHLY enjoyable.

I'm by no means a senior dev, but I don't know if I fit in the box of a junior either.

Regardless, SQL is proving enjoyable. But I really like logic, so it fits.

CobaltFire··on A Man Who Reads Books for a Living (One Every Two Days)
I think it gives various passages and questions from a bank.

Mine was a paragraph about small loans to poor populations, and had five questions.

CobaltFire··on A Man Who Reads Books for a Living
Can't say I ever took a test like that. 644wpm and 100% in English (native language).

Hard to judge that based on just five questions though.

CobaltFire··on Reverse engineering circuitry in a Spacelab computer from 1980
I have zero experience with anything in the space program, but this all looks REMARKABLY like the F/A-18 Avionics I worked on for years. The board connecters look identical to what most of those boxes used, as well as the test benches (I'm specifically familiar with the AN/USM-484). The circuit board designs, etc. all have a ton of similarities as well.

I imagine it was a function of the design constraints in that time period, and similar program needs.

There are very few records of any of this out there, similar to the Spacelab equipment I imagine. The -484 ran a Harris H100 minicomputer with an HP terminal and a GPIB bus. I've linked one of the few photos that you can find, but it's from an extended version of the test bench and has the minicomputer rack off to the right cut off.

Sorry for the off topic, but it's always cool to see stuff like what I spent years working on come across this site!

CobaltFire··on Was my $48K GPU server worth it?
I have a 5090 machine sitting idle that I'm considering turning into a machine for my own small team (3 devs).

Are you willing to share any lessons learned, etc. that I could make use of? We are evaluating paying for a SOTA sub or trying this, and the talk about Qwen3.6-27B makes me want to try deploying this machine.

CobaltFire··on Nobody understands the point of hybrid cars [video]
I have a van that does all of that better. Seriously.

Mercedes Metris, and I average 27MPG driving it like I do my Leaf.

It's also amazing for going to the water and being able to change in it, going skiing and being able to dress out, etc.

SUV's are hugely overrated. I have a 4WD (GX470) and honestly we rarely ever drive it because even for fire roads the van is more than capable enough.

That said, it IS a niche vehicle. I'm rather sad they didn't catch on more.

CobaltFire··on Goodbye Visa and Mastercard: 130M Europeans switching to sovereign payment
Correct, and it used to be AMEX.
CobaltFire··on Goodbye Visa and Mastercard: 130M Europeans switching to sovereign payment
To be pedantic American Express and Discover exist.

But I agree with your meaning. We are beholden to some third party no matter how we move in the current situation.

CobaltFire··on American sentenced for helping North Koreans get jobs at U.S. firms
Not in the slightest.

Its both about your decision making in getting to that point, and about what you might do to get out from under those debts.

Exactly the issue we see in this situation.
