Ask HN: As a first-time solopreneur how would you go about hiring the first team

I am interested in understanding how would a solo tech founder hire the initial sales, marketing, operations, cyber security and DevOps team members?Assuming that I don't know anything about or have zero experience in the skill-sets I am hiring for, how does one start? What questions to ask, what to look for and where to look for the talent?

Ask HN: How many of your users use IE11 to access your web app?

Recently I came across some data from the UK government on how many people use IE11 to access their services. The figure is around 350K. That is quite a sizeable number. The data, if I recall correctly, was from 2022.So, I was wondering, how many of you still support IE11; and how many of your users, in absolute numbers, access your app using IE11, and what is the percentage of that user base...

AI's Diminishing Returns

A random number generator uses a seed value. The larger the seed value domain, the more unpredictable the "randomness" of the generator. The "randomness" of a generator with finite domain(even if it derives new seed values from old values) ultimately becomes predictable and hence useless.The "AI" systems, as currently designed, could face a similar problem as a random number generator with...

Ask HN: What web frameworks/technologies did not succeed as per your expectation

We come across some web frameworks and technologies that we think will succeed, but they wither away as time passes by and don't succeed to the level we expected.Which web frameworks and or technologies did you come across that you thought would succeed but did not as per your expectations?For example, I thought that Opa Lang[0] and UrWeb[1] would succeed but did not, even though the ideas were...

Ask HN: How to efficiently calculate subscription price for a webapp?

Say, I have a webapp and I decide to charge customers per month for using this app. I base my price on infrastructure cost, operations cost, labour cost, profit etc.That price goes up as per the rise in the costs and profit margin. But there is also something that incurs cost for the app developer, and that is data retention cost. For example, say, a customer generates 5gb of data each month....

Ask HN: What is your base template for first time communication with a prospect?

Say you have built a product or about to build a product. And you have identified some prospective customers. Now you want to connect with them, via email, phone or in-person. So what is the base template you use to communicate via various channels like email, phone etc. Of course you will customise it for each prospect, but you will be starting from some base template that will be customised...

Isn't mind and a brain two different things? I thought computers and neural-nets were modelled on a brain and not on mind.

Ask HN: Why did Nim not catch-on like wild fire as Rust did?

I skimmed through Nim website and some code snippets, and see very exciting features such as macro support, pythonic syntax, transpiles to C/C++/JavaScript, no VM, systems programming language, suitable for hard real-time systems etc. So why has it not caught on as wild fire like Rust?Also, what is its FFI story? How easy it is to interop with C++ and JavaScript?

You will need to define "successful" within the context of your question; only then you will get meaningful answers. Because there are lots of solo entrepreneurs who are successful as per their own definition of success which may or may not match with your definition.
Re:A Confession Exposes India’s Hacking Industry on Tuesday June 06, 2023 @09:24AM (#36212310)
India has a hacking industry?

Seriously, I can understand scamming industry presence in India, but hacking industry, if at all present will be very nascent.

Edit: In the title it suggests "confession", but it most likely was bragging :)

It is an unwritten(?) convention that all depiction of time should be 10:10. Don't know why that is but I learnt about this convention when a political party[0] in India launched its symbol, an analog clock.

Ask HN: What Happened to Fuzzy Logic?

Fuzzy Logic was a very talked about field few decades ago. What is the state of that field of research? Is it still being persued or are there applications of it already implemented commercially?

Re:OpenAI came after our domain because we use GPT in it on Thursday May 18, 2023 @05:18PM (#35994178)
This reminds me of a conversation with a CEO of an US startup working on Java hardware accelerator. They named their company JEDI, which was an acronym for the IP they had developed.

One day they received an email from Lucas Arts objecting to the use of the name JEDI :)

The startup had to change its name.

Can it(the database) do simple pub/sub without third-party software? :)
Startups, if successful, grow into bigger companies. But why do you think bigger tech(or non-tech) companies are not entangled in bureaucracy?

A government is far bigger and complex than any big company. So there will be more slowdown compared to big companies.

One example of successful public-private partnership is India's "Digital India" initiative where the government was able to churn out platforms like Aadhaar, Unified Payment Interface and RuPay, with other platforms on the way for digital commerce for MSMEs.

Ask HN: Data Capture for Audit, Security and Analysis?

As a solo developer just starting a simple web app project, what data should I capture for Audit, Security and Analysis? And how do I capture and store this data? I was thinking of storing the data in a database, but the size of the database increases substantially and it becomes very expensive quickly.What is your approach to store audit, securit and analysis related data without increasing...

Writing mathematical proof is like writing code, compiling/interpreting(take your pick), debugging, fixing problems, and testing; all at the same time, and that too in real-time.

That is the reason more people find programming enjoyable but struggle with mathematical proof writing.

Oh, what could go wrong!

Why is there no discussion on users losing their private keys? Ask all those cryptocurrency users who lost their private keys. Now don't tell that there are crypto wallets/vaults that manage private keys; there are many ways key can be lost even when using wallets/vaults.

We engineers live in a different world, disconnected from the regular users who have no clue what public-private keys are!
