Thanks for corrections.

Me too ! Kidding aside, if you would be interested in a job programming mostly or partly in D please see our website. Lots of roles we haven't yet had time to post.

"join us" for "submit an application" -> apply (confusing otherwise) Maybe sum up and make clear that each student can earn between $3000-4000, instead of capped at $1k. Why limit it to students? If the goal is to have a youth injection, just use an age limit- say 18-25- I see no reason for the stupid college bias.

Hi Joakim. Thanks for suggestions. I don't know what legal aspects there are relating to targeting age in different countries. We are definitely targeting people earlier in their careers. I agree with you that talent isn't only found amongst students, and I've in the past hired someone that didn't even finish high school and has gone on to do good work for the D community. So as far as Symmetry goes we are very open to unusual talent. A degree is just one piece of interesting information. https://symmetryinvestments.com/careers/ There's quite a lot of work involved in organising something like this, and I'm very grateful to the D Foundation for doing such an excellent job. We can refine this for next year, but I wanted to make a start. Laeeth

Sure, thanks for funding this worthwhile initiative.

Yes, but the current requirements exclude, for example, recent college grads who may not be employed yet and might do much better work than a harried college student. I don't know the legal risks in detail, but I can't imagine the risk/reward to opening it up would favor the current limitation.

This is why I suggested stating the total sum clearly: "20 hours/week for four months for a salary of $1000 seems kind of crappy. Am I reading this wrong?" https://www.reddit.com/r/programming/comments/8yram3/comment/e2gttg2 You're currently requiring people to read carefully and do the math to understand this: most people do neither.

I'd suggest adding the following to SAOC 2018 project proposals : 1/ adding a Go-like http module to the standard library 2/ adding Go-like async IO management to the standard library, i.e. fibers communicating through blocking channels 3/ possibility to use automatic reference counting (with weak references) instead of garbage collection for automatic unused memory deallocation 4/ adding automatic cycle detection and collection to the automatic reference counting system (https://wiki.dlang.org/SAOC_2018_ideas) Thanks :)

Sad. Then I'd suggest to add the event loop implementation to SAOC 2018 too, because the absence of a default http module in D's standard library may have very good justifications, but I'm still convinced that it doesn't help when trying to "sell" it to modern developers, considering that nowadays MANY of the applications they will develop in a professional facility will have to integrate http code to access or update the company's data.

I've said, that if we get signatures, I'll build the damn thing myself. Signatures give a very lightweight vtable implementation while also giving conceptual representation of structs+classes. Which for an event loop, is a very desirable thing to have. But alas, I'm waiting on my named parameter DIP and seeing where that goes, before continuing work on signatures.

Proposal: Multi IDE debugger support (for windows) Mago, the debug engine used in VisualD, has also a tool called Mago-MI which has a GDB compatible interface. Therefore you can use on Windows Mago-MI as replacement for GDB. Several IDEs uses this feature to enable debugging with 1 code line for Windows/Linux/MacOS. It is used in experimental state in IntelliJ, also there is support in Visual Studio Code and of course DLangIDE for which it was originally built. There are several issues which could be addressed in Symmetry Autumn of Code: - Mago-MI is written in C++. This makes bug solving hard. Rewriting of Mago-MI to D might make sense. - While the installation of Mago-MI is easy if you want to debug OMF executables it is very hard if you want to debug COFF executables. You need another executable from Mago, you have to register DLLs via regserv and you manually have to create a registry entry. An installation procedure for installing Mago-MI would be great. - There are some bugs in Mago-MI / and DMD (wrong debug information) which makes debugging hard. (https://github.com/rainers/mago/issues/21, https://github.com/rainers/mago/issues/23). Also Mago-Mi misses features (https://github.com/rainers/mago/issues/14). There are more bugs but not investigated so far. - As Visual Studio Code is already is already a topic for DLang Foundation, using this as reference user of Mago-MI would make sense. While this proposal seems only windows related, the nature of Mago-Mi is to enable IDEs having 1 code line for debugging on Windows/Linux/MacOS. Therefore overall investing into this topic is good for all platforms. Kind regards André

Another proposal: Adding D support to gRPC I started to add D support to gRPC but paused it due to lack of knowledge and time. One solution would be to add a D wrapper to https://github.com/grpc/grpc/tree/master/src by making use of the C interface of gRPC (https://github.com/grpc/grpc/tree/master/include/grpc). As template e.g. C++ or python could be used (https://github.com/grpc/grpc/tree/master/src). Kind regards André

I'm interested in the "Graphics library for resource constrained embedded systems" project and have some spare time this autumn, but I have some questions: - Does this project aim at creating a hardware-agnostic rasterizer supporting a few primitives like https://skia.org/ or implementing a full GUI library like emWin rendering widget and handling I/O events such as mouse? The latter one sounds a little bit challenging to finish in four months - In the past year I primarily wrote C++ and don't have much experiences with production-level D programming, can I get involved into this program?

IMHO no need to reinvent the wheel for that. You can probably do both in four months, if you just "port" (separately) and bind the code of the two following libraries : 1/ swGL (https://github.com/h0MER247/swGL) 2/ Nuklear (https://github.com/vurtun/nuklear) They have a very open design, and are already quite well optimized for speed and memory consumption. Moreover this would allow the D port of the Nuklear library to also use a hardware accelerated renderer on desktop platforms. Nice isn't it ? And I'd be glad to mentor you on this :)

Thanks! Porting seems to be easier than creating a library from scratch. The Nuklear library looks like a great candidate for porting since it only has a few external dependencies. swGL, however, depends on a large set of C++ standard library and threading model, which makes it difficult to create a dependency-free port. Moreover, The term "dependency-free" in the project description often confuses me, because as a hardware-agnostic library the project does have to depend on external implementations like "sin"/"memset" or even "thread_start", and I'm not sure which kind of dependency is proper for this project: Should we assume a multi-threading model? Should this library rely on "malloc"/"free"? Correct me if my understanding is wrong since I had few experience on embedded programming.

There is more to this project than just getting a software rasterizer in D. Part of the goal is to demonstrate D as a formidable alternative to C in micrcontroller firmware programming. D will never achieve that notoriety if it's always depending on C, the C runtime, the C standard library, or some library implemented in C. So, IMO, if you need to link in a library or object file that was not compiled from D code, then you're cheating. This is also one of the reasons why I suggested re-implementing software building blocks such as `memcpy`, `memset`, `malloc`, `free`, etc. in D as another potential project for the Autumn of Code. So, to keep this software rasterizer project within scope, I suggest creating naive implementations of those functions in D for now to stay true to spirit of the project (no dependencies, everything in D), and "make the point". You can those software building blocks in their own module, and let the user of the software rasterizer library link it their own implementation if they wish to deviate from the spirit of the proposal.

That's actually what I am doing now. Currently I wrote a short script to ensure the symbols in the main project within a subset (https://github.com/htfy96/rasterizer-d-embed/blob/master/check no-und-symbols.sh). I also plan to create some basic dependency-free building blocks like memcpy/memset/memcmp (already implemented in https://github.com/htfy96/d-rlib) and malloc/free (maybe reusing some building blocks from std.experimental.allocator?) in separate projects. Regarding floating point operations, I plan to use dmd.builtins/ldc.builtins instead of linking with libm. Above this well-defined set of primitives, the core rasterizer will be built, so that users can plug in their own implementations or use the default implementation when libc/libm is linked.

That reminds me. Something else to consider is that some of these microcontrollers don't have FPUs. Graphics libraries designed for microcontrollers often use fixed-point math as a lowest common denominator. I think, given the features of D, fixed-point or floating point could be selected at compile-time. But, I don't wish to expand the scope of the project. An all-floating point library would be fine, IMO, and fixed-poing math could be added to the library in a future iteration. Mike

Having already implemented a video game engine using exclusively fixed point math for a nintendo handheld, I can tell you that the rasterizer code will have to be implemented with that in mind. Using several precisions (16.16/20.12/40.24 formats) and 64 bits products, avoid divisions, etc. A very different beast IMHO, even with fixed point structs overloading the different math operators...

There is more to this project than just getting a software rasterizer in D. Part of the goal is to demonstrate D as a formidable alternative to C in micrcontroller firmware programming. D will never achieve that notoriety if it's always depending on C, the C runtime, the C standard library, or some library implemented in C. So, IMO, if you need to link in a library or object file that was not compiled from D code, then you're cheating. This is also one of the reasons why I suggested re-implementing software building blocks such as `memcpy`, `memset`, `malloc`, `free`, etc. in D as another potential project for the Autumn of Code. So, to keep this software rasterizer project within scope, I suggest creating naive implementations of those functions in D for now to stay true to spirit of the project (no dependencies, everything in D), and "make the point". You can those software building blocks in their own module, and let the user of the software rasterizer library link it their own implementation if they wish to deviate from the spirit of the proposal. Mike
I agree But this BetterC minimalistic standard library (allocations, arrays, strings, slices, maps) is something which can be reused by many similar hardware-level projects. This is a project on its own, and as I said, I think it should better be provided to the candidate so he can use his development time on developing the rasterizer, and, if there is enough time, a minimalistic nuklear-like gui system over it to demonstrate its performance and usefulness.

Indeed, having to port the druntime to new hardware is definitely not in scope. I can't anticipate what features of the language the developer will employ, but as long as they stay within the -betterC subset of the language, I think it will be portable to something like that used in https://github.com/JinShil/stm32f42_discovery_demo Even if it isn't portable, if it compiles and runs in -betterC on a PC, it will still be an excellent foundation to build on, and I'd still call it a success.

I say, no. To get threads on microcontrollers, you typically first need to implement a Real-time Operating System (RTOS). If you want to implement an RTOS in D, and then build the rasterizer on that, that would be very cool!....but also very challenging ;-) Mike

+1 Then I agree that Antigrain is probably the best reference code for the antialiased renderer, as its code is small, very complete (ttf/gsv/raster fonts, top quality antialiasing, etc) and reasonably fast. IMO the better-C standard library runtime should be provided to the developer in charge of developing that rasterizer.

I can't say too much about this as I'm not that familiar with the proposed project, but here's what I can say: it's just a suggestion. It's definition isn't set in stone and is just a pointer to a problem to get you started. For more pointers and discussion, I recommend to ping Mike (https://github.com/JinShil) as IIRC he was the one who proposed this project and could also be a potential mentor.

Yes. Applicants aren't expected to be D experts. Also sound experience in C++ will definitely help you (especially for such a low-level project). AFAICT a sound proposal and showing that you are serious about the project/commitment is more important than your D history. There are a few posts in the D blog about the GSoC in 2016 (https://dlang.org/blog/category/gsoc) which provide a few more insights, but in short none of the students from GSoC 2016 were well-known member of the D community before the GSoC.

I'm JinShil, the one who proposed the idea. As far as I'm concerned, if you're doing the work, you can make it into whatever you'd like, but I would consider a basic 2D, anti-aliasing rasterizer to be a success. I have in mind something like http://www.antigrain.com or Skia. A bonus would be a font renderer that leverages the aforementioned rasterizer (See also https://medium.com/ raphlinus/inside-the-fastest-font-renderer-in-the-world-75ae5270c445). The software should be efficient enough to use on embedded systems like https://github.com/JinShil/stm32f42_discovery_demo Under that constraint, you'd probably want to try to accomplish the task with the -betterC-like subset of the language (https://dlang.org/spec/betterc.html). That being said, there's no reason the software couldn't be used on a PC with resources to spare, and it would probably be easier to do the development on a PC and just verify the implementation on an microcontroller periodically. I, myself, don't have much experience in graphics, so I don't know if I'd be a very good mentor, but if you have any questions about the goal or use case for the project, let me know.

Well, I won't be the one paying you, and I don't think I'll be the one evaluating your work, so I don't think my opinion matters, but as the one who proposed the idea, I'll just explain my point of view. Microcontrollers have limited CPU and memory resources. Generally, they operate by filling a dedicated buffer in RAM (width * height * pixel_format_size) with pixel data. The size and format of the pixel data is generally decided at compile-time based on the needs of the application. Some microcontrollers have a dedicated hardware peripheral to aid in the blitting and blending of pixel data, but most don't. So, for all intents and purposes, this project is a software rasterizer in D; you definitely won't find any CUDA cores here. Understanding the capabilities and limitations of the microcontrollers will give you some perspective and understanding about the design tradeoffs you will most certainly need to make, but, once you have that perspective, in the end, you're just filling a buffer with pixel data, and I don't see why one couldn't do the vast majority (if not all) of development for that on their PC. That being said, getting a low-speed MCU with as little memory as 256KB animating an LCD display can be a thrilling experience. If you're interested, I suggest obtaining one of the STM32 Discovery Kits with a built-in LCD screen. See https://www.st.com/en/evaluation-tools/stm32-mcu-discovery-kits.html?querycrite ia=productId=LN1848 (Typically one ofSTM32F4 or STM32F7 models) This is the one that I have, and it only costs about $30: https://www.st.com/content/st_com/en/products/evaluation-tools/product-evaluation-tools/mcu-eval-tools/stm32-mcu-eval-tools/stm32-mcu-discovery-kits/32f429idiscovery.h ml#samplebuy-scroll Furthermore, I've already created the platform code for you at https://github.com/JinShil/stm32f42_discovery_demo, so you should just need to import your library to main.d and try it out.

Sorry, I seem to have missed that. But to quote from the SAoC page [1]: "If you are interested in becoming a mentor, please submit an email to social dlang.org and let us know which project, or what kinds of projects, you would be willing to mentor, as well as the number of hours per week you can make yourself available to your code during the event. The event organizers may ask for more information, such as examples of your level of experience with D, before deciding to accept your offer." I appreciate anyone volunteering as a mentor, but if it isn't sent to me at that address (or my personal one), I can't guarantee I'll see it. [1] https://dlang.org/blog/symmetry-autumn-of-code/

Be careful here. ASCII is easy to render, but Unicode isn't. Unicode requires BIDI support and a bunch of other stuff which are projects in of themselves.

I was 14 and a half when I implemented my first depth buffer based rasterizer, in 6502 assembly on a C64, for a hi-res mode 3D renderer. The algorithm, despite being "naive", is actually still an efficient one even now. I stored an array of x/depth ranges (one per raster line), and updated them while drawing the wireframe points of the 3 clipped edges, while updating the y range of the triangle. Then I simply iterated on the triangle y range and drew the inner points (between minimum_x+1 and maximum_x-1), using the filling color and interpolating depth. Clearly not realtime as my character-based wireframe renderer, I admit it. But this more than fast enough to quickly render a hi-res 3d scene in memory in *filled* mode. So this "dumb" algorithm may still be worth being investigated in your case, as this C64 implementation was meant to run on a rather similar hardware (very limited memory and CPU, only fixed point operations, etc). Just add antialiasing on the wireframe edges and you're done...

 (https://developers.google.com/open-source/gsoc/faq#is_gsoc_considered_an_internship_a_job_or_any
form_of_employment) stating that this program is an "employment" or not.
I can't definitively answer whether not the U.S. government would consider it work, but I can tell you that neither Symmetry nor the D Language Foundation consider it employment; they view it just as Google does. I'll add that to the FAQ.

Unfortunately, after checking this issue with a US visa attorney, I found that if I want to participate into this project, I have to work as a volunteer and receive no compensation in any form now or in the future. I'm really willing to join this program, so I was wondering that can I work as a non-paid volunteer in this program just for accumulating experiences? If so, may I work for less than 20 hr/w with some easier goals? Thanks

What about being paid for the work via your home country?

Strictly speaking, F-1 visa prohibits getting paid without CPT/OPT as long as I am physically in the US. In practice, working remotely and getting paid via another country while staying in the US is a gray zone, but due to the fact that the immigration policy is getting stricter these days, I don't think it's a good idea to risk a visa revoke :(

 Another issue of this program is that me, as an incoming 
 graduate in the U.S., are prohibited to "work" in my first 
 school year. (that law doesn't affect GSoC since summer is 
 considered as the second school year). I'm not sure whether 
 contributing to open-source projects is considered as "work" 
 here. There are some legal issues related. I'm looking forward

I'm not an attorney working on immigration law, but Symmetry is not a US company AFAIK, so I don't see how that is relevant. Of course you should check with someone with appropriate expertise first.

Thanks to everyone for the project ideas, but I put the list on the Wiki for a reason. I'm always pressed for time, so if you have an idea for a project suggestion, it would help me tremendously if you can just summarize it on the Wiki rather than here. Thanks!

Example of idea for student: A deep learning framework using together a LLVM SPIR-V enable and https://github.com/libmir/dcompute would be awesome
