Jetroid··on My dad launched the quest to find alien intelligence
It might not need to be about technology, but biology, à la War Of The Worlds.

Whilst I doubt that (all of?) our viruses would have any effect on them (as they require our own cells to reproduce - aliens are unlikely to have a similar makeup), but things like funguses and bacteria could be very very bad for them.

In case the author reads this, it would be nice to have a 'night mode' option.
Jetroid··on Drive through cities in the browser while listening to local radio stations
I absolutely love this.

As the creator of Dream Catalogue once wrote:

"I spent a lot of 2013 listening to spacey drum & bass mixes while watching Hong Kong and Tokyo night driving videos on YouTube and drinking beer, just because the combination of it all created such a weird feeling I have never experienced before."

I love these kinds of videos. Pairing it with a local radio station gives me the kind of feeling that you get whenever you first arrive in a new city.

You're gawking out of the window of the taxi/bus/train as the city and landscape goes whizzing past. Just drinking it allll in

In those moments you feel there is a whole world of opportunity that awaits you. You don't know what you'll find there. You get lost going over the possibilities that await. Will you find friendship? Opportunities? Love? Enlightenment? Anything could happen.

But in that moment, those are all just possibilities. So you sit. And you watch. And you think.

And then you snap back to reality when you reach your destination. You step outside, are briefly assaulted by the heat and moisture - or lack of it - and sometimes you see or smell things you've never encountered before.

You blink, breathe in, and take your first steps in this new place that you will be calling home.

Jetroid··on How many of you know that the team is working on something that no-one wants?
The government only cares if you're developing something that will make more money, which presumably selling via the internet will.

It doesn't have to change the world, as long as it moves the needle.

Jetroid··on Discussion on renaming master branch gets heated, then shut down
There's a lot of 'broken' software that assumed any Windows version number with a 9 in it was made in the 90s. That doesn't mean that we can (nor should) throw out that software.
Jetroid··on Discussion on renaming master branch gets heated, then shut down
Maybe it is offending people, maybe it isn't. I hold no doubt that the concept or slavery is offensive, but I haven't actually seen an argument from a PoC saying that it offends them. Nobody alive today was a slave during the time that it was legal in USA/UK, etc. I'd hold a very different view if we were having this discussion in the 1800s. As I said, I haven't actually seen any significant outcry about this from the relevant communities, for lack of a better term.

My argument goes more along the lines that changing something like this can cause more harm than good in some cases, given that we have years of established documents using these definitions.

As an example from science, the reason that the direction of conventional current goes opposite to the flow of electrons is because we found out new information, but decided it was too costly to change.

If we remove the Master/Slave terminology from everything new effective today, then in 20 years, will a new developer know that 'Main/Secondary' in their 2021 datasheet is referring to the same thing as 'Master/Slave' from their 1991 datasheet?

Possibly, but also maybe not. A smart person could infer this and another could search it, but there is still potential for confusion.

Jetroid··on Discussion on renaming master branch gets heated, then shut down
Whilst in theory, I'm neutral to the change on ethical grounds, I think in practice it will make things very confusing.

Master/Slave is such an established pair of terms in tech that they have a loaded meaning as soon as you see them.

If I see 'Master' and 'Slave' on an old hard disk, I know what that is. If I see "Configure one device to the master setting and the rest to slave.", I get a understanding of the relationship for free.

I don't think we will get that with replacement terms, at least not in the short term, and we're just setting ourselves up for confusion.

Jetroid··on A Guide to Pic Microcontroller Paging
We can write to PCLATH without causing a jump. PCLATH is only read when we goto somewhere, or call a routine, or write to PCL.
Jetroid··on A Guide to Pic Microcontroller Paging
OP here,

We prefer to use PIC microcontrollers because they come in a DIP package.

Our products are mainly sold as PCBs that a customer assembles in their own home, appealing to the DIY electronics market.

For many, SMD is challenging, so having a DIP package makes us more available.

Additionally, the ability to use less power is useful because our products do not have an onboard power supply, instead relying on the rack's supply that may be shared between many products.

That's a great perspective, thank you.

Funnily enough, I'd consider this post to be on the borderline between a micropost and a regular post.

Of all of my microposts, it's the one that I dedicated the most time to - though still much less than a post that would go on the homepage.

You've really hit the nail on the head though. By writing every day-ish, it lead me to start this post, which made me realise that I needed/wanted to dedicate a lot of time to to fully explain and say what was on my mind. (I reordered some of the paragraphs and added bits here and there, which I didn't do for most microposts to keep them 'micro')

By trying lots of posts, I found one that I wanted to go into detail with, which ultimately lead to it being the first post of mine to rank on the HN front page. Wow!

Thanks!

I think the styling is fine, it's just how it copes with responsiveness.

Try opening it on your phone and flipping over to landscape, or on an ultrawide monitor, or even just resize your browser window to be really wide.

It's a mess, it makes me anxious every time I share something.

I know that I have to fix it for the edge cases but I kinda dread doing the work to do that, haha.

Jetroid··on Starting Many Things
Yes, when I got that lecture, it made me think about my own life and made me wonder if I was just 'exploiting a local maxima' or if I was really on the right path for optimality. I figured that it was almost certainly sub-optimal, but without having many thousands and thousands of retries like an agent, what can you do?

My path to where I am today also has many little 'chances' where my exploration lead my in a completely different path that I wouldn't have been on today.

Like when I was a young teenager, and discovered a forum about a video game that I liked. From there, I picked up video game level design because I was inspired by a couple of the posters. After a while of that, I discovered game scripting, which lead me to pick up programming. When I entered Sixth Form at school, I picked up Electronics on a whim and ended up realising that I really liked assembly language. Things grew from there until I got to where I am today.

Jetroid··on Starting Many Things
I'm aware. I made this website's CSS before I knew about how to do responsiveness properly. Almost everything is based on viewport widths in some way. It's a real mess and I simply haven't had the time / seen the value to change it. My tiny little site rarely gets any visitors worth talking about.

I'll try to do something about it soon. Thanks!

Jetroid··on Why Does Windows Really Use Backslash as Path Separator?
I think the intention was that 'foo/bar' and 'foo' would be in the same directory, therefore when typing C:\foo/bar into the file explorer you would have an ambiguous path. Perhaps I misunderstood.

Jetroid··on Simple calculator written in pure HTML (no script) – proof of concept
Very interesting. It reminds me of template metaprogramming in C++ as (assuming you generated this, and didn't write it by hand) the computations were completed at compile time!

Similar thing, but I once needed to see the readout of a binary transmission coming at a baud rate of 31250Hz using a low quality (and hence minimal featured) oscilliscope. The individual bits were too fast to see in real time, so I used to slow-mo camera to record it, and got what I needed.
Jetroid··on Show HN: Beat video game addiction
As a former 'video game addict' myself, I can't overstate how important I think this project is.

I never used Game Quitters myself, but I wish I had. I wish that I had found Game Quitters when I was younger, as Video Games were essentially the only thing I was living for. Video Games prevented me from getting outside and experiencing the world when I needed it most - when I was a deeply unhealthy kid who couldn't walk and who had been hospitalised and away from people his own age for a few years. Some things, like social interaction, I still struggle with today, and I wonder if that would have been the case if I quit video games.

I'm lucky that my path in life moved me away from Video Games, but I know others aren't so lucky. This is why I think the world needs Game Quitters to raise awareness of these issues.

I met Cam two months ago, and just by my interactions with him, I realised that even after a year since I last played a video game, it still has a big effect on my lifestyle and thought patterns. I've found Cam's Game Quitters YouTube channel helpful in indentifying those problems.

I think it says a lot that when I wanted to learn web development, the first thing I made was from a video game. And even now, I still find myself watching videos and streams of gaming from time to time, and Cam's work has helped me to realise my actions are having a negative impact on my life.

Jetroid··on Why Don’t We Forget How to Ride a Bike?
Anecdotal, but perhaps interesting:

I rode a bike every few weeks with my father as a child. When I was 11, I had a pretty serious health condition including paralysis from the waist down. I had to spend several years retraining my muscles to be able to walk and run again.

I'm 22 now, and have just (literally in the past two weeks) started riding a bike again. I wasn't particularly confident but I was happily surprised to discover I had no issue just riding. I'm having trouble with U-turns and signalling, but this feels pretty cool considering that half of my life so far has gone by without riding.

Jetroid··on Show HN: I recreated the Fallout hack minigame. Shows posts from my blog on win
Hey HN!

I just got finished working on this yesterday. If you don't know what Fallout is, or what the hacking minigame is , you can check here[0] and here[1], respectively.

My version displays the hacking minigame, and then when successfully hacked, it displays the posts from my website, exactly as if it was on a terminal in the game.

I originally made it two years ago as a way to learn HTML, CSS, and JavaScript, but it had some huge flaws as I was a beginner. In anticipation for the release of the new Fallout 76 tomorrow, I went back to it and reworked huge portions, and it's now at a point where I'm ready to share it with the world!

I wrote a short writeup of the original development process and my motivations here[2], and a much longer post listing the improvements I made these past two weeks here[3].

This project has definitely been a labour of love for me, and I'm really proud of it and happy with it. I hope you enjoy, and I'd love to hear what everyone thinks!

Jetroid··on It's time to head back to RSS?
> it's a feed of news curated by google supposed to match our interests

Really? I've always found it to be awful, majority things I am not interested in.

I just checked, and only 2 in 10 were mildly interesting to me. Three of them were about sports, which is way off the mark for me.

Does it optimise based on my interactions with that application in particular, or is it meant to be linked with the rest of my google account?

Jetroid··on Sudan, last male northern white rhino, dies in Kenya
No, an invasive species is one that is an alien to the area and that is likely to cause damage to the ecosystem it is now present in. [1] Human influence is the main cause, but species may get there by other means. [2] Transport vector is unimportant to the definition of invasive species or not. One study considers a definition where species which are native but that are causing ecological damage could be considered an 'invasive species'. [3]

Also from [3]:

> Invading propagules begin as residents in a potential donor region (stage 0), some of which are taken into the transport vector (stage I), usually by humans. If these propagules survive transport and release to become introduced (stage II), they have the potential to establish (stage III) in a novel environment.

Note that 'stage I' notes 'usually by humans', not 'by humans'. Ie. a species which uses some natural phenomena as a transport vector can still be considered an invasive species. [1] says similar - "Human actions are the primary means of invasive species introductions." - implying that non-human methods are also possible for invasive species introductions.

It's nonsensical to say that as soon as something migrates using a natural phenomena that it becomes a 'native' to that area.
