God damn fucking shit.

Now I know again why I don't do apps.

This is a app as simple as can be:

Enter a link, click a button, do a http request, download a file.

BUT FUCKING HELL WHY ARE YOU SO FUCKING RETARDED ANDROID?!

I'm not familiar with java but i don't care why is this so freaking unintiutiv to get shit done? Why are there thousands of ways and none works or atleast at a easy way? Make an object for this, make an object for that...

THIS IS RETARDED.

In PHP a simple "file_get_contents" would do the job. I were even down for some curl shenanigans if it were an easy implementation. BUT GOD DAMN.

URL url = new URL("http://fuckinghardcoded.com")

Oh no can't compile because that MIGHT be an invalid URL. Ok try catch this or just tell the rest of the Programm to watch out for this bad boy cause he might throw a MalformedURLException.

Ditch that and try volley. Everything is document except how to fire that queue! Does it do that by itself? Do I really have to do an override to a function while declaring? CMON ON I'M A WEBDEV IS THIS TRYING TO DO A FUCKING CALLBACK AND IS THIS TRYING TO BE AN ANONYMOUS FUNCTION??? Why is this so frustrating and confusing? I'm also mad at myself this is dropdead simple shit but I can't get it to work. Fuck this, fuck java , fuck android and fuck myself

I just want to say,
wow the Cloudflare API is awesome.

In less then an hour (from a blank file - to automation and tested) I was able to setup a DDNS task that basically just pulls my public ip (see https://devrant.com/rants/2050450/... for details) comparing it to the current DNS records for and update them if anything has changed in the past 30 minutes.

So kudos to these guys letting me in next to no time having a simple yet elegant way of dealing with my missing static ip.

Why can’t all APis be this simple?

Is there any exact way to get the product of all primes under n multiplied together, without explicitly knowing what those primes are?
Lets call this number V.

Because hypothethetically, if we calculate from the *base* of V, then we can derive easy divisibility rules for V-1 and V+1, as laid out

And then, unless I've misunderstood something, the problem of factorization has been changed from division into an addition and subtraction problem.

Okay, we must first establish common ground here. What do we understand about "showing"? I understand you probably mean displaying/rendering, more abstractly: "obtaining". Good, now we move on.

What's the point of a front-end? Well, in the 90's that used to be an easy answer: to share information (not even in a user-friendly way, per se). Web 2.0 comes, interaction with the website. Uh-oh, suddenly we have to start minding the user. Web 3.0 comes, ouch, now the front-end is a mini-backend. Even tougher, more leaks etc. The ARPAnet was a solution, a front-end that they had built in order to facilitate research document-sharing between universities. Later, it became the inter(national) net(work).
First there was SGML to structure the data (it's a way of making it 'pretty' in a lexicographical way) and turn it into information (which is what information is: data with added semantics) and later there was HTML to structure it even further, yet we all know that its function was not prettification, but rather structure. Later came CSS, to make it pretty. With its growing popularity, the web started to be used as a publishing device.

If we are to solely display JSON data in a pretty way, we may be limiting ourselves to the scenario of rendering pretty web pages using aesthetic languages such as CSS. We must also understand that if we are only focusing on making a website pretty with little to moderate functionality, we aren't really winning. A good website has to be a winner in all aspects, which is why frameworks came into existence, but.. lmao, let's leave that to another discussion.

Now let me recall back my college days.. front-end.. front-end.. heck, even a headset can be a front-end to a pick-order backend. We must think back to the essence, to the abstract. All other things are just implementations of it (yes, the horrendous thousands of Javascript libraries, lol).

So, my college notes say:
"Presentation layer: this is the UI.

In this layer you ask the middle tier for information, which gets that information from a database, which then goes back to middle tier, back to presentation. In the case of the headset, the operators can confirm an order is ready. This is essentially the presentation tier again: you're getting information from the middle tier and 'presenting it' as it were.
The presentation layer is in essence the question: how do I bring my application data to my end users in a platform-and solution-independent way?"

What's JSON? A way to transport data between the middle tier and the presentation tier. Is that what frontend development is? Displaying it in a pretty way? I don't think it is, because 'pretty' is an extra feature of obtaining and displaying data. Do we always have to display data in a pretty way? Not necessarily. We could write a front-end script (in NodeJS perhaps) that periodically fetches certain information from a middle-tier is serves a more functional role rather than a rendering one.

The prettification of data was a historical consequence of the popularity of the web (which is a front-end) (see second paragraph with link). Since the essence of a front-end is to obtain information from the back-end (with stress on obtaining), its presentation is not necessarily a defining characteristic of it, but rather an optional and solution-dependent aspect, a facet.

Some time ago I was looking for materials regarding Ansible automation tool and realized that most of them suggests setting up the lab environment using virtualization (like VirtualBox). In my opinion that is not the best approach – virtual machines consume lots of resources and take some time to start/kill. So I decided to write a guide for setting up Ansible lab environment using Docker containers. Containers require significantly less resources than vm’s and can be bring up and down really quickly. Additional advantage is easy way of automating whole environment using docker-compose. You can find my guide at github: https://github.com/LMtx/... Any feedback is very welcome :)
