timthelion··on I give up on free software phones (2019)
I use lineage on oneplus phones and have no problems. I can't do internet banking and a bunch of other non-free things, but really, who needs that? I have a web browser. The only thing that doesn't work is google meet and google docs and google drive because they intentionally break the mobile experience in the web. But there is a simple solution. Simply don't use google services. If/when my employer demands that of me (occasionally I hear murmurings) I just tell him I'm online 9-5 on my laptop and if he needs me he can call. I'm happy with my lineage.
timthelion··on Royal Navy says quantum navigation test a success
Do military subs have antenna buoys on cables that they can raise up without having to surface?
timthelion··on Bard is getting better at logic and reasoning
How is Bard widely available. ChatGPT is available worldwide, Bard isn't in Europe yet.
timthelion··on Retiring the AWS Documentation on GitHub
Why do you want to work for free to make AWS better anyways?
timthelion··on The death of self-driving cars is greatly exaggerated
Humans have two eyes that move in sync and can measure distance using the auto-focus feature. They can both point at an object and autofocus to figure out how far that object is. I don't see teslas using moving binocular cameras with 10th of a second autorefocusing in order to judge distances. I don't see how it is the same thing. Of course we can play GTA with just vision, but I'd argue the average person crashes in GTA more than they do in a real car.
timthelion··on Solar will soon eclipse other forms of energy generation
I like to run client code in a VM and my nuclear reactions several light minutes away. It's just basic hygiene...
timthelion··on Nvidia DGX GH200: 100 Terabyte GPU Memory System
They do. See wikipedia [significant figures] https://en.wikipedia.org/wiki/Scientific_notation#Significan...

In this case, it is pointless though, since the precision is actually known.

timthelion··on Nvidia DGX GH200: 100 Terabyte GPU Memory System
There is a semantic difference: 1,000,000 == 1,000,000 where-as 1.00E+6 >= 1,000,000 < 1,010,000. The decimal places after the 1 in 1.00E+6 specify the precision of the measurement.
timthelion··on Emissions are no longer following the worst case scenario
I believe total emissions are being measured by satellite spectrometry and not by reported figures. So if these are the numbers from the satelites they include all emissions including warheads, oceanic die-offs, permafrost melting ect. Or are those numbers different?
timthelion··on PyPI will require 2FA by the end of 2023
Wait, what? I'm so confused. How is this security theatre and how is it better to have curated packages than an open ecosystem when it comes to "hostility"?
timthelion··on Animals Are Dying in Droves. What Are They Telling Us?
Aha, sorry for my mistake. I didn't mean "apartment" to mean that you have to rent.
timthelion··on Animals Are Dying in Droves. What Are They Telling Us?
Doesn't that suggest that India should go to war with the world? I'm pretty sure that 110m2 is pretty luxurious for most people on earth.
timthelion··on Animals Are Dying in Droves. What Are They Telling Us?
That's weird. I grew up in a big house and my parents had plenty of cars, meat and travel, but I wasn't particularly happy. I'm happier now in my small apartment. I don't really understand how a big house will make you happy. Really, doing electronics is more fun in a hacker space than at home, and you can always go to a park.
timthelion··on Animals Are Dying in Droves. What Are They Telling Us?
I am actually in the same boat. I have limited myself to the things I list, yet the problem is still there. And The human population doubles every 50 or so years even after I had a vasectomy [1], and yet my emissions aren't going to cut in two in that time.

[1] https://ourworldindata.org/world-population-growth

timthelion··on Animals Are Dying in Droves. What Are They Telling Us?
I think that if everyone gave up air travel, individual automobile transport, and meat and dairy and lived in a max 110m2 apartment you could say that. But it seems that there are a lot of people who simply don't care.
timthelion··on Running a movie theater is more expensive than you can possibly imagine
Strangling your customers doesn't seem like good business.
timthelion··on My friends who cheated in interviews are getting promoted (2022)
Having grown up in America and moved to Czechia for college I have to say that I was absolutely shocked by the level of cheating both by Czechs as well as those from "farther east" like Ukraine and Russia. Just brazen obvious sheeting like taking notes into exams and hiding them. Cooperating during exams. Even collaboration to distract the teacher during exams. When I was at college in the US getting caught cheating once meant an instant fail for the course. Twice meant you were kicked out of school and you'd have a cheating mark added to your credit transfer paper so you couldn't move your college credits elsewhere. In Czechia, getting caught cheating meant having to re-take the test. Nothing bad happened to cheaters and they cheated rampantly.
timthelion··on Federal Zoning Bill Would Preempt Local Parking Mandates
As far as I know, that's not actually a federal mandate though, it's a federal condition on the provision of funds. States can refuse the mandate and the money.
timthelion··on Google Translate “Get well [Swedish firstname]” translates to “fuck you”
What percent of HN readers know a Slavic language? It is true, though, in Czech at least his user name is Faithful Black
timthelion··on Europeans drain billions from banks, fed up with shrinking savings
Actually you can remove money from circulation by buying T-bills from the fed.
timthelion··on Europeans drain billions from banks, fed up with shrinking savings
There are no high interest banks. 2% in EU is very high interest.
timthelion··on Massive geothermal apartment complex is going up in Brooklyn, first of its kind
It's not entirely passive, you have to have a pump that moves the water through the loop, but it can cool the house without running a heatpump, with just passive heat exchange. Or with the heatpump running at a minimal level because when it is really hot outside, the ground is relatively comfortably cold.
timthelion··on Massive geothermal apartment complex is going up in Brooklyn, first of its kind
Well:

1. You get passive cooling in the summer 2. The greater the temperature difference is the more efficient the pump becomes so they are more efficient even in not so cold weather 3. The maintenance costs of the system are significantly less. You need to clean and replace blower fans. Cleaning has to be done yearly or twice yearly depending on environment. Ground source, you only need to maintain the pump and coolant which needs replacing cca once every 20-30 years.

timthelion··on Massive geothermal apartment complex is going up in Brooklyn, first of its kind
Nothing to steal here, except for the pump itself its all extremely deep underground.
timthelion··on Generative AI set to affect 300M jobs across major economies
"Affecting jobs" is really a short term problem that can be addressed with training and probably bridge loans from the government. It's not like we've run out of problems to solve. There are still diseases to cure, environmental issues such as climate change and habitat loss to address, the human yearning to "spread to the stars" and colonate Mars. Loneliness, unhappiness, the desire to have a real person make a hand cooked meal, the desire for better television shows, the desire for better video games, the desire for more immersive less seasickmaking AR/VR. There are a million things that need to be done, so why are we so afraid of running out of things to do?
timthelion··on Ask HN: How do you think LLMs will affect society medium/long term?
LLMs are absolutely amazing at writing unit tests. This really speeds up development a lot. I think we will see the creation of much larger, more complex code bases which will be even more complex than what we have now. And the demand for programmers will drastically increase. At the same time, it will be even harder to get into the profession as the already limited opportunities for junior devs will dry up. Perhaps we will move to an apprentice model in which senior devs will take on apprentices with some expectation of loyalty, or just out of civic duty.

I think all this software that we will create will end up being used to optimize a lot of processes such as power generation, agriculture, and manufacturing. We will have specialized software for recycling things, leading to a much more circular supply chain. Right now it doesn't make sense to sit down and figure out how to clean, test and repurpose objects, but it will make sense once computers get smart enough.

In terms of jobs outside of computer science, as everything on the production side gets more and more automated, we are going to see much much more paid emotional labor. More people working in coffee shops, bartender/therapists, paid pen-pals ect. We will also see a huge growth in the services for end of life. Now, people who are dying often lay uncared for in group homes, alone, sad and frustrated. In the future, there will be people reading novels to them, and doing finger painting with them.

Every child will have the opportunity to have private tutors.

Medicine will start to work and biological mortality will decrease.

We'll go to the stars.

Maybe I'm just dreaming...

timthelion··on Ask HN: How do you think LLMs will affect society medium/long term?
Yep. I used to find people to help me write/correct professional emails in Czech (it's my second language). Now I just let chatgpt give me feedback. According to my previous mentors it does a very good job at this. I give it a prompt like:

Hello, would you please check this email for typos and provide general point by point feedback:

<body of email in Czech>

It responds with something like:

Thank you for your email. Here's my feedback:

- The opening greeting "Dobrý den" is appropriate for formal communication in Czech, but it's not clear who the recipient of the email is. It's always a good idea to include the name of the person you're addressing to personalize the message.

- "napad" should be "nápad" with an accent mark.

- "Uvažuji o možnost kombinace nerezové časti se tradičný deskou tak že by byla dva kusy tradiční desky které bych vzal ze bauhausu a jeden kus nerezu se dřezem." This sentence is a bit long and complicated. I would suggest breaking it down into smaller sentences for clarity. Also, "tradičný deskou" should be "tradiční deskou" with an accent mark, and "nerezu" should be "nereze" with an accent mark.

- "Mohu poptavat nasledujici:" could be phrased more clearly. You could say "Můžete mi prosím zaslat následující informace?" to ask for the information you need.

- "Deska se dřezem 230cm dlouhé (trochu jsem opravil i velikost dřezu)." This sentence is not clear. It would be better to rephrase it to something like "Potřebuji desku s dřezem o délce 230 cm. Změnil jsem trochu velikost dřezu."

- "2x nerezový lem pro připevnění na klasickou desku aby lem byl ze stejného materiálu a vyšky. 211,5cm a 41,5cm." This sentence is also a bit confusing. It might be clearer to say "Potřebuji 2 kusy nerezového lemu o rozměrech 211,5 cm a 41,5 cm pro připevnění na klasickou desku. Lemu by měly být stejného materiálu a výšky jako deska."

- The closing "Děkuji" is appropriate, but it might be nice to include a closing statement or a salutation, such as "S pozdravem" or "S úctou."

I make my changes and we go back and forth about 4x before we're both satisfied. It is much faster than bothering friends and relatives and the results are perhaps even better since it gives me more freedom to keep my own voice (friends and relatives often have hard headed opinions on how to communicate which are unrelated to language).

I can Transform Your Legacy Codebase into a Valuable Asset

Hello. I am a consultant specializing in old and poorly documented code bases. I have been writing code for over two decades and have worked with over a dozen languages including: Python, Rust, golang, C, Java, Javascript, Typescript, Haskell, and Elm. I can dive into an unknown and poorly documented code base, document it, write tests and provide professional on-boarding videos to get your team up to speed. I provide comprehensive training and documentation to ensure your team can effectively maintain and enhance your legacy codebase long after our engagement is over. I can also diagnose, reproduce, and fix hard to understand bugs in complex systems. By bringing old code bases up to modern standards I can help you harvest the valuable IP assets you already have, driving new growth and stabilizing the technologies upon which existing revenue streams rely.

I work with companies of all sizes, from startups to established enterprises, who are looking to modernize their legacy codebases and improve their technology stack.

With my help, I can transform a stagnant legacy product into a proven technology which you can believe in and sell.

Past projects include:

- Updating and documenting a legacy telecom diagnostics system which processes hundreds of gigabytes of Netscoute data every day

- Upgrading [django-helpdesk](https://github.com/django-helpdesk/django-helpdesk) to use class based views and performing a security audit on accessible endpoints

- Migrating a mid sized organizations server infrastructure from a diverse set of hosts: EC2, Heroku, VPSes to a unified kuberentes cluster, implementing a fully automated and rollback friendly CI/CD system.

- Maintaining, developing and administering a large Django application used for a bike to work event

- Design and implementation of the POSIX device subsystem for Docker 1.0

- Diagnosing a critical and hard to reproduce bug in Elm-lang's runtime.

- Author of [subuser.org](subuser.org]

timthelion··on I hired 5 people to sit behind me and make me productive for a month
I don't mind being weird. I also went to a public park dressed like this:

https://hobbs.cz/wearable-computing/adventures.html

Obviously it's important to make sure you aren't bothering other people in a way they cannot easily ignore. You shouldn't make too much noise, especially at night, or create too much smoke or other bad smells. But being weird hurts no one. Why should I limit my own freedom out of fear of being weird? If it seemed to have a negative effect on my job prospects I might be less weird, but I find the opposite is true. Being weird has probably had a negative effect on my dating life. Then again, I don't want to date someone who is going to restrict my creative freedom by hating my weirdness anyways. Being a coward is far worse when it comes to finding dates than being weird, and being weird in public can help you learn not to be a coward.

I also see letting it all hang out publicly, warts and all as being a sort of protest. If the only ones publishing coding streams were the [Jon Gjengsets](https://www.youtube.com/c/jongjengset) of the world, people like me might simply give up. Surely I'm not the only imperfect coder. Surely I'm not the only one in the world who has spent 10 hours bashing my head against the wall because of a silly typo. I'm here to shout from the hilltops, that it's OK to play amateur football. We don't all have to bend it like Beckham to have fun!

I guess the main thing though is, that I don't really believe anyone will watch all my videos, so I don't feel self conscious doing them.
