2rsf··on Ask HN: How do you get comfortable with shipping code you haven't reviewed?
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
2rsf··on I realized bad lighting is quietly hurting productivity (and no one measures it)
> 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

2rsf··on Ask HN: Is it still worth learning a new programming language?
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.
2rsf··on So you want to speak at software conferences?
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
2rsf··on So you want to speak at software conferences?
> That said, it’s not my strong suit. Others are far better at it than I am.

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

2rsf··on So you want to speak at software conferences?
> 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··on Ask HN: Binary files in Git repository, what is you workaround
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.

2rsf··on Show HN: We built an open source, zero webhooks payment processor
> I issue invoices only after a successful payment, because I owe tax on all invoices including unpaid

(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.

2rsf··on Unpowered SSDs slowly lose data
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.
2rsf··on This World of Ours (2014) [pdf]
Yes (TBD)
2rsf··on This World of Ours (2014) [pdf]
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

2rsf··on Accessing Max Verstappen's passport and PII through FIA bugs
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.
2rsf··on Accessing Max Verstappen's passport and PII through FIA bugs
(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?
2rsf··on Greenland’s national telco, Tusass, signs new agreement with Eutelsat
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.
2rsf··on Ask HN: Why is it so hard to design an open-source smartphone?
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.

2rsf··on Ask HN: Why is it so hard to design an open-source smartphone?
And it's not just the individual hardware components, at these small scales building and integrating the components is a big challenge
2rsf··on Ask HN: Best way to create a searchable knowledge base?
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··on Why I have to buy doughnuts with cash
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.

2rsf··on Ask HN: Why is software quality collapsing?
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··on Ask HN: Where can I genetically test myself without risking privacy?
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.
2rsf··on History of Telecommunications T-Carrier
> Some sweet hardware money was made dealing with that

I used to work in a company that made good money on those

2rsf··on Ask HN: What Is Your Hobby?
Cool, when I grow up I plan on ordering one of those "build you own watch" kits
2rsf··on Ask HN: What Is Your Hobby?
I am not sure how to separate a hobby from plain interest, the real hobby I do is building scale models, from plastic cars to wooden ships, although I don't have enough time for it. I like to read, and have an interest in watches but don't count those as hobbies though.
2rsf··on Ask HN: What Is Your Hobby?
While I'm into it as well, but how do you define it as a hobby? Some people tinker with watches, building or fixing them, but does owning a few watches and discussing them online count as a hobby?
2rsf··on Permeable materials in homes act as sponges for harmful chemicals: study
The article doesn't seem to have immediate actionable recommendation, and is mainly a brick in a wall that can lead (or not) to better design decisions.

One unclear point for example is what happens with the deposited toxins, how hard is it to clean them? are they transferred by touch?

2rsf··on Tell HN: Opt-out of LinkedIn training content creation AI models
I don't know if I should opt out or not. The "yes" is quite obvious- why should I give Microsoft my thoughts, time and writings for free? on the other hand we can't ignore the fact the AI is becoming the new search engine, and being included is a way to show up on "search results"
2rsf··on Privacy and Security Risks in the eSIM Ecosystem [pdf]
I read some of the article and stil not sure what is so unique about eSIM compared to physical SIMs. Is routing user traffic through third-party infrastructure unique to eSIM?

The other risks mentioned are mostly rare edge cases

2rsf··on Wanted to spy on my dog, ended up spying on TP-Link
There could be another scenario. I assume that factory resetting the camera will bring back the default password. Factory reset is a long press on the power button (in some cheap TPlink camera), so in theory someone with physical access can take control over the camera without you noticing until you try and use it.
2rsf··on Ask HN: What is your average acceptance rate for code suggestions from an agent?
The industry standard (according to some research, articles and my own company experience) is around 30%.

This is as reported by the agent or research so I am not sure what it means, did you scroll through some options or had to re-request one, but it points to a low rate of acceptance

2rsf··on Ask HN: Is your company still hiring junior engineers?
My company stopped hiring. Period. But when it did hire juniors were definitely hired, some even fresh out of school or internship programs. AI is not affecting us to the level you are worried about, we are far from a time where AI will replace engineers or even reduce their numbers- at most it will make junior engineers more productive.
