I think I need to investigate more about them. I just had a quick look and from what I can see there may be little difference over what I already have, so I may have been a bit hasty in my "I'd take one" :D

On the one hand, the price you propose is a no-brainer. It's a similar cost to a Raspberry PI!, on the other hand, I have tonnes of stuff here already.

Let's see what others have to say.

I'd be up for one - but I'm sure you're not really after individual takers. No idea, but I assume the postage from Aus would be a bit of a kick in the nuts?

I believe you read correctly. Although he won't know me from Adam, I've subscribed and followed his videos on YT for some time now and yes, he's making a "new" case.

In all honesty I think Aros craves an off-the-shelf machine that can be bought. Just how powerful are these things? Are we talking Acer Aspire type machine or more powerful?

How much depth do you want to go into? It alone is not going to give you the knowledge to work on an OS, that's for sure, but that's always the battle and nothing to do with knowing a language. Programming languages themselves are usually relatively easy to learn. Sure there are always complex parts and subjects like pointers, generics and so on (I'm mixing languages here), but the basic language is usually quite straightforward. It get's complex when you have the syntax nailed and want to know how you can do stuff. Then you need to know your subject. Libraries, API's, hardware, how things work and so on.

Anyway, getting back on-topic, the book I mention covers all the bases from a C syntax perspective, delves into some of the more complex topics, structures, pointers,function pointers, linked lists, types, unions, etc.

It also goes over the standard library and some of the usual things you will need like file I/O and stuff. It seems to have a section at the end on UNIX for some reason - file descriptors, I/O etc.

I should probably say that I've never read it as a book. I don't think I've ever read a programming book cover to cover, they are simply not that exciting whoever the author! I used it as a reference when attending night class and go back to it when I need a refresher on something. Usually either recursive include files or pointers because as someone that dips in and out of C, they are the things I tend to forget.

What it will NOT tell you, is how build systems work, how make and meta-make work, GCC and so on. It probably covers how to compile something - I don't recall, back then we were using some MS-DOS based environment. But that's not strictly part of the C "language" as such.

Err, if you enter "the c programming language kernighan" into our friend google, you might find that assuming you get the same results as me, the second link is not expensive at all !!

Whether it is entirely legal or not is not for me to judge or condone one way or another - just passing on what google is giving.

[EDIT] But you are correct, in paperback, I do remember it being a lot of money for me back when i was in my late 20's - probably explains why i laminated the covers and looked after it all this time.

The C compiler does not understand different human languages, only it's own - the C language. In C a float has a '.' for the decimal point, as it does in maths in general so I'm afraid that if you want to add two floats you need to enter them with the dot for the decimal place.

So, how do you handle the different language formats for numbers (called a Locale)?

You need to enter the value as a string or more technically an array of chars and then YOU have to process that string to convert it to the standard numeric format that the compiler is expecting to receive. There will be more than 1 way to do that, you could do it manually by looping over the string to replace the ',' with a '.' and then convert the string to a number, or no doubt there are library functions in the C language that will convert the string to a float taking into account the input locale (I genuinely don't know off hand). But the point is, if you want to enter two numbers in your own locale you will have to convert them. The C compiler won't understand them as-is.

If you are serious about learning C then I would highly recommend buying a copy of "The C Programming Language" by Brian Kernighan and Dennis Ritchie (RIP). It is widely respected as the "go-to" book on the subject. I bought a copy when I was at night school in the mid 90's and it is still next to my desk all these years later.

There are some aspects of C that will likely fry your brain at first (pointers and the like). If you're really lucky you'll get it quickly, if not, having the book handy will be helpful. I need it around from time to time because at the moment I do not work in C for a living (I used to around 2000 and also from 2012 - 2016). I also do not know if there are translated versions in, for example German or if that is even a problem?

Just to say that something committed this week has resolved this issue under ABI_v1.

Not much help for Icaros at this point I know unless it was a specific code change that could be back-ported. I haven't looked into that yet.

[EDIT] Just to clarify - by 'this issue' I mean the one where I get a crash when I click 'Use' in Wanderer prefs.

I haven't had time to go back to this yet this week - maybe over the weekend. The basic keymap was working fine but I think I need to setup a couple of layout alternatives to handle minor differences in Apple's various keyboard incarnations. At least as far as the ones I have here anyway:

- Old style mechanical with see-through base and numeric keypad
- Wired Aluminium with numeric keypad
- Wired Aluminium without keypad
- Original Wireless aluminium without keypad (not magic)
- Mattias Aluminium Bluetooth Mac keyboard with numeric keypad

All British Macintosh layout with variations. I guess I will ultimately add them by model number.

Anyway, I don't have an ABIv0 build environment but I have no problem with creating one as I will like to use the result with Icaros hosted myself :)

[EDIT] Ahh, I just realised that I have misunderstood what "Alternate" does in "Input Prefs". I though it was for where there is more than one variation of a keymap but it is for if you want to switch between two entirely different keymaps.

OK, perhaps I won't consider all of these minor variations and instead just support the main 2 or 3 recent ones.

I looked at this when I saw the announcement. It took a while because it is very confusing because most of the site is based on pushing the Aeros distro rather than just Amicloud.

I came to the conclusion that you do not have to buy a recurring plan. You buy the client at €5 per platform (Windows, Morphos, Aros etc.) and this will get you the basic 5 or 6GB of storage. I guess you have to register an account somewhere to use the clients because obviously they will ask you to login. But that's where it gets even more confusing!!

Where do you register? Everything seems to point to an IndieGo account but I couldn't really work out what one of them is because as far as I could see, and IndieGo! is a linux based PC that Aeros-shop sell.

Yeah, it was very confusing so in the end I didn't do anything. Maybe it is not so confusing if you have followed from the beginning and have one of these Aeros computers?

I also had a question...

What is the deal with the Amicloud service? Where is the data held? On whose servers? How do we know it is secure, etc., etc. With DropBox, OneDrive, etc. at least we know the company and we all more or less trust the service to be secure (as best as we can anyway, probably shouldn't put unencrypted sensitive data into cloud services). But I know nothing about Amicloud or where it has come from.

It looks like a great tool but I'd like to know more.

Are you responsible for all the moving elements in the background of that web page? It just made the CPU on my i7 Surface Pro 4 reach over 80% and the fan go full blast. I dread to think what it would do to an Amiga, or Amiga-like. I didn't stick around to read the content, I rarely do when a web page does that.

Just saying :D

I'll take it offline and do some work to try to determine whats going on. Including trying out debugging. That will be an interesting and worthwile exercise in itself!

Clearly as you've both said there's a few relatively straightforward things I can do to see if it's an oddity with my system: 1) download nightly binaries to rule out my manual build, 2) build a Centos 7 VM and try again there.

I also have no problem whatsoever with changing my host to some other flavour if at the end of the day I determine that to be the issue. I'd prefer to put some work in rather than go to older versions and I have to say I prefer to stay away from Centos, purely because we used it for years in production and it gave me a lot of headaches, but that was for reasons that have no bearing here and were mostly Microsoft's doing.
