100% agree with the "you don't", but I wouldn't be surprised if young startups or highly stressed teams delivering low-risk products will do just that and deliver unreviewed code

> Is lighting an invisible variable in productivity that startups are ignoring?

There are two questions here- lighting is a known factor influencing productivity, you can easily google that.

Are startups ignoring it? I don't have any data showing that, but I wouldn't be surprised

LLM's are far from perfect, any production grade code must go through a human inspection unless it's a tiny ad hoc app. This means that you need to be familiar with the languiage and the environment to get good quality code.

I suppose it's a combination, some people are more comfortable speaking and improvising on the spot but everyone needs to practice. I can add to your list a CEO of a big bank, he speaks freely and it's a pleasent to listen to him, but I heard that he practice using a private instructor as well

I don't know you, and I feel the same about my public speaking but I suspenct that there's a lot of imposter syndrom in that

> 9. render the presentation as a pdf file, so any device can display it

That's good as a backup, or for simpler presentations (in a good way!) but Powerpoint allows you all kinds of benefits like animations or transitions. Presnting PDFs is not guaranteed to be pain free as well, as I expereince on my corporate controlled laptop with stange versions of Adobe software.

> 11. the anxiety goes away

It does! also remember that the audience doesn't know what you are going to present, so they wouldn't care if you make mistakes.

I will add

13. Practice and learn speaking, a good start could be Vinh Giang's Youtube channel

2rsf — Tue, 02 Dec 2025 13:33:19 +0000

Depending on the context, git lfs for essential binaries, Artifact/Asset Repository for high volume of binaries like build or test artifctas.

Security and the avaialble scannning tools are also part of the decision, and so is the expected usage- do you expect to consume the resource outside of the context of Git.

(IANA I am not an accountant) but how is it legal? as a customer you want to pay against an invoice, and AFAIK it is required by law in most places.

I was in a team that wrote the firmware to handle that 15 years ago, with focus on automotive implementations where temperature might be high and access to the data is harder.

a. I am too lazy to search but they probably did, the problem was what was done with the information. Same with 8200 the all mighty signal intelligence corps

b. The Mossad is the equivalent of the CIA, they are not meant to act inside Israel

It's even worse, you find a key that you know belonged to your neighbor so you try it out just in case in his door.

(playing the devil's advocate here) But that's not the case- if you find someone's physical keys in the street, will try to open the neighbor's door with it? so why is it ok to use a password that you "found" to log into a site?

Somewhat related to that, but Israel is launching satellites in the opposite direction than the rest of the world when they launch from their shores, this is so the launch is done over the Mediterranean sea and not their neighbors.

Regulatory Certification is also critical, you are not allowed to use home made RF devices, especially if they are connected to a network of certified devices.

For example the latest cellular standards use shared medium- everybody are transmitting on the same frequency at the same time, but you need to follow strict guidelines for power control and coding. One malfunctioning phone transmitting too strong can disturb a whole cell.

This is hard to achieve using an open source model since tests are conducted on finished products, whole assembled phones.

And it's not just the individual hardware components, at these small scales building and integrating the components is a big challenge

Add an MCP server to each and ask your favorite AI assistance? as an example if you are in the Microsoft business environment then Copilot (the MS one, not GitHub) can find information for you across sources.

2rsf — Fri, 17 Oct 2025 06:51:03 +0000

But that's not sustainable, pulling out random amounts out of your wallet without knowing your current balance will get you into cash flow problems.

If you are responsible and know your balance, then using a debit card, or equivalent app, is the same as using cash.

New comment by 2rsf in "Ask HN: Why is software quality collapsing?"

2rsf — Tue, 07 Oct 2025 10:16:24 +0000

I used Win 95 and NT and computers today are blazingly faster, but obviously requires much more resources to achieve that.

Win 95 was not only slow, but also prone to hangings of all kinds and it was hard to keep it up for more than a few days without a crash or a needed reset.

Consuming a huge amount of unnecessary resources is a modern problem, but it doesn't make software quality any less, well depending on how you define quality.

The bug in the 1980's Therac-25 software killed people, bugs in the Patriot system causing it not to intercept Iraqi Scuds killed people in 1991 and the Mars Pathfinder required an interstellar software update in 1997 to fix a bug.

2rsf — Thu, 25 Sep 2025 07:40:15 +0000

That's the best advice. I have seen some genetic test results. They are not simple to interpret and it is not easy to know what to test for- every person has natural defects and mutations which not always translates to real diseases.
