Nice! Been looking a lot at EU based software I've been working with on an automated deeptech job board just for EU as well - https://deeptechjobs.eu/

I though about having something like this! This can be a great tool! For engineers this can be a great tool to summarize the standup update, or even to recall what did we do yesterday I'll check it out now

"It struggles with LLM text streaming, parallel processing in Ruby[3], and lacks strong typing for AI coding tools."

What's the struggle specifically? How these general articles of opinion get to the first page of HN I'll never understand. Just random statements without anything to back them up.

This looks awesome!

I'm currently in the process of making my MySQL database stream it's change-data events, and I feel the pain of stitching all the apps together to make it happen.

This seems to be a killer technology.

What a bunch of whining babies. Are you really this upset with such a tiny change? :D

I like the new editor. They shouldn't revert the changes. Like any change on any software, people will complain first, some issues will be solved, and then will adapt and stop complaining.

How can this have such an impact in your lives?

Stop slacking and work ;)

Coal kills more than nuclear. Modern nuclear is safer and reliable.

It's similar to the fear of planes vs the actual safety statistics of planes.

Ask HN: Master vs. Udacity nanodegree

pgcosta — Fri, 16 Sep 2016 19:00:17 +0000

What is your opinion, in terms of added value, of an university master in machine learning vs udacity machine learning nanodegree?

I want to further progress my education, but am very divided: masters are expensive and long (2 years in Barcelona).

Udacity seems more accessible(moneywise), and has also the advantage of being taught by world leaders in the field.

What's your opinion on the matter?

pgcosta — Tue, 14 Jul 2015 12:32:42 +0000

Nope. If you want to develop software for critical system(medical appliances, satellites), this should be a must. The only problem is the cost of implementation. On top of that you also have to account that there are non deterministic problems in Hoare logic, like finding the cycle invariant.

"It’s really the engineers making the pre-race setup for the car and making real time adjustments during the race"

"8.5.2 Pit to car telemetry is prohibited." source: http://www.formula1.com/inside_f1/rules_and_regulations/tech...

"F1 drivers merely are “along for the ride”" This is wrong on so many levels. F1 is a very physically demanding sport. Their reflexes have to be as good in lap 40 as they were in lap 4. They need to perform changes to the car in real time, mostly between turns, as they're told. They need to know how to attack, defend, overtake, save tyres, save fuel.

The difference is that 10/15/20 years ago they did all this without not much data, and now they have much more context to each decision.

You clearly do not watch much Formula 1.

New comment by pgcosta in "Programming is not math?"

pgcosta — Fri, 18 Jul 2014 22:25:44 +0000

That is the problem: programming should be math. If we view programming as metaphysical, we can never hope to build good software. That will change in the future.

I don't believe that 50 years from now we will be still writing code to fly a plane or run a web app, and questioning ourselves: will it run? will it crash? Does the code does what it is supposed to do? Do these two functions do the same thing? Certainly as time goes on, programming will be ever more a well defined formal system, so much that big parts of development will just be auto-coded(by machine).

That is why functional languages are so good. They are very close to mathematics, and allow us to build formal systems on top of them, that remove any ambiguity that might exist. And this is(or should be) one of the reasons why functional programming is so 'hip' now: it allows us to reason about program design using the Algebra of programming.

Of course right now we are stuck with the methods we have to build software. And that means you can have a programming job without knowing much about math, or even using it day to day.

But that will change in the future. (My humble thoughts on it, based on the views I got from a university class called 'program calculation')

if you are curious about algebra of programming, although there are many more resources online: http://wiki.di.uminho.pt/twiki/pub/Education/CP/Bibliografia...
