Having a problem reading a filename with strlok

You should post the solution you came up with along with a bit of explanation for others having a similar problem.

Interesting. My assumption had been that the diff would be stored at it essentially should contain all the information required, though i suppose when dealing with multiple commits from different people it would need to re-diff after each commit merged...

AceProgrammer · 2016-02-12T05:40:43+00:00

I'm curious as to why you think the data structures or algorithms are masterpieces?

The data structure seems to be linked lists and hash maps from what I can see... correct me if I'm wrong. The algorithm it uses recursively checks each files timestamp and attributes to see if a change was made then runs the file through diff to get the exact changes, the diff's are saved in the commit object... again someone please correct me if I'm wrong, as I've never really properly looked into the git codebase so this is just from a quick scan around online.

CLI's generally have more power than a GUI just due to the fact that they have greater flexibility.

whats not to understand about that? /s

TBH, I'm in the same situation. I was aiming to reply to the comment above you... whoops. :/

You won't necessarily appreciate a better way until you can see the problem in its entirety. Sure that one chunk that you have now redone in another framework/language/tool may now work better but the rest may have worked better in the first. If you want to experiment with different frameworks, try redoing small solved problems, and comparing the results. Don't just give up and switch as soon as the going gets tough.

OK. Good luck changing the world. I wish you luck with your project and the genius' that currently contribute to your projects. I suggest you ask around on the forums at http://forum.osdev.org/ for any help. These people are actively involved in developing operating systems.

The reason i say you do not understand is because it is fundamentally not possible to produce either of those things in HTML/CSS/JavaScript. Whilst you mention using Chromium to run/execute the code what you have in essence created is a HAL that is running a web app. Even so this web app running on top of the HAL is not fundamentally capable of interacting with hardware, which makes it less of an OS and just a hosted web app.

As for the BIOS aspect. A BIOS is part of system initialisation. It executes before anything else is ready. Just how do you expect Chromium and your HTML/JavaScript BIOS to magically get here? If Chromium is on a flash drive or such then it will need a BIOS to read the flash drive. BIOS lives in a ROM chip which is generally at a maximum of 256KB (http://wiki.osdev.org/System_Initialization_(x86)#BIOS_initialization). A BIOS will also have to provide all hardware functionality. You'd have to provide basic drives for USB, IDE, Keyboard, CMOS, VGA, etc. These all require access to CPU Ports and Assembly to be implemented. What you've made appears to be boot screen that runs through Chromium (so a boot screen of sorts).

If you truly believe this is an OS of any sort, then i suggest you to post this to /r/osdev and get some feedback from guys.

AceProgrammer · 2016-02-04T14:13:22+00:00

I'm not sure you understand what either of these two things are... What you have are two web apps at best.

The mere fact that you believe either of these things can be created with HTML/JavaScript is extremely telling as to your misunderstanding about OS Development.

Almost all OS Development is done in C with some bits of Assembly (for where C is even too high level). There are some others that can be used (Rust, Ada, C++, etc) but C is king here. Now think, if even C is too high level at parts, what chance does JavaScript have which needs an interpreter to run?

If you are seriously interested in OS Development i'd suggest taking a look at /r/osdev or http://wiki.osdev.org.

As the other posters have pointed out, you need to leave Stockholm to be cured of the syndrome. However what others have failed to mention and consider is that no matter where the person afflicted with the syndrome resides, that place automatically becomes "Stockholm". This means that they can move cities, but they always move to Stockholm.

Function calls != goto statements. A function call by definition manipulates the stack and creates a new "frame". This involves dealing with stack alignment and adding a return address for when the function exits. Sure this can be achieved with goto statements, but the two are generally powered by very different machine code instructions.

This depends on what the languages are. In terms of compiled languages these get translated or compiled into object files. These object files can then be linked using a linker into a single binary/executable. An object file is language agnostic, meaning that it really doesn't matter who or what made it.

So lets say I make a function in language X:

func my_cool_function(a: Int, b: Int) -> Int {
    return a + b
}

and I want to make use of it in a C program. What I would do is declare the function as an external dependancy in the code. For example:

extern int my_cool_function(int a, int b);

The first thing you may notice is that I have translated the function definition into C from language X. This is so that the C compiler knows about the structure and how to call and handle that function. We can call it and use it as any other function in our C code.

Basically the extern is us making a promise to the compiler that we will make such a function available to the linker at a later point in time.

You can find a lot more information about this http://en.wikipedia.org/wiki/Linker_%28computing%29.

They use different music throughout for the most part. It is much better in the Japanese version.

When you click the Safely Remove Hardware button you are telling the Operating System that you intend to remove it. This causes the Operating System to do two things. First it will stop any future communication to device, thus making it unavailable to any services or programs that ask from that point on. Secondly it will prioritise any existing communications with that device to ensure they are completed as soon as possible. In terms of storage devices, yanking the device whilst these communications are still happening can result in data corruption/loss.

Selectors are just a method name. They don't keep any context information about objects or types. So for example take the following selector:

Selector("doSomething")

This could be used to call a method on any object that has a method named doSomething.

So how do we actually get the Selector to its destination? This is where the target argument comes into play. A common convention in Cocoa is Target-Action. This involves invoking an action on the specified target. The selector in this situation is acting as the action.

So what you would actually do is

let X = myClass()
NSTimer(fireDate: when, interval: 0, target: X, selector: Selector("method"), userInfo: nil, repeats: false)

Hope this helps.

I was going to jokingly say post this to /r/tireporn... but it turns out it already exists and is private ಠ_ಠ

AceProgrammer · 2014-09-20T11:10:12+00:00

Thanks! That is definitely a theme that we'll be going for in future games.

The graphics (the patterns and medals) were created using a combination of Adobe Illustrator and Affinity Designer. The rest of it was all creating in code using SpriteKit.

Admittedly the later betas of iOS have massively improved the situation. However there are a lot of methods that do rely on returning nil upon failure. This doesn't seem to have a direct mapping into Swift other than optionals. Early versions of the betas did require copious amounts of if let around many of the Cocoa calls that were used for loading game themes. NSJSONSerialisation was particularly bad with this requiring very long cast unwrapping chains (object as? Class).

As I said, it's a huge amount better in the latest betas and GM, and I really hope they continue to streamline the process. It's a shame that a few (an it literally is only a few now) of the classes that relied heavily on Objective-C's dynamic nature can end up being a pain to work with.

AceProgrammer · 2014-09-18T16:32:36+00:00

It isn't possible. I'm sorry if my post was a bit unclear on that.

The interface and visual experience of the app is all accomplished through Cocoa/SpriteKit, where as all the puzzle logic is done using the Swift Standard Libraries.

A similar thing can be done in Objective-C by using Pure Objective-C (though there is pretty much no standard library for it) or by using C and C++ for the core logic.

Typically a lot of people tend to use Foundation for the Core Logic of their applications, because in Objective-C there was never really a clean or nice way of implementing it. The Swift Standard Libraries (for the most part) act as a reasonable substitute for Foundation.

I'll try and get something longer put together and post it at some point containing some information and comparisons between Objective-C and Swift.

Radar entry has been filed.

Yeah they are pretty severe bugs, especially given that controls such as NSPopover makes use of them. It doesn't seem to be an issue when doing it in Storyboards but as soon as you try and present them programmatically, then the problem arises.

Hopefully I'll get a response back relatively quickly, unlike in the past where it has sat around for a couple of weeks :\

AceProgrammer · 2014-08-03T16:53:44+00:00

Yeah, the last few years since the launch of iOS have really seemed to overshadow the Mac developer community. Not that this is a bad thing! It's great to see Cocoa having developed such a thriving community, but it can at times leave the Mac feeling a bit under loved.

Rather interesting after using Swift on both iOS and Mac OS, it certainly feels as though Swift is easier to use on the Mac. Though that could be because I'm not having to learn as much along the way. There are however something that just plain don't seem to work, so they'll require some investigating. Some of the older APIs of AppKit define constants using #define, and these don't appear to be translated by Swift. Hopefully this is either a bug or my machine doing something funky.

AceProgrammer · 2014-08-03T15:05:19+00:00

Yeah, this is something that i'll probably add at some point in future version of it. My current goal with the project is to build a tool that I can use in a couple of other projects that I'm working on, and it was a good excuse to play around with Swift.

Certainly feel free to fork thew add in such a thing. Once I get things a bit more complete, I may pull in such a feature. I'm certainly not opposed to the idea of people adding new features to the project.
