I have a Canon PowerShot S120, which allows for browsing / copying photos over WiFi. There are apps for Android, iOS, and Windows to do that. The protocol uses upnp to discover the camera and the smartphone/computer and them some HTTP-based protocol. I have some code using libupnp for the discovery and a perl script that is capable of transfering one file, but it's far from complete. Plus, I need to refresh my memory, because the last commit is from January :-(. Now, there seems to be some support for such cameras in gphoto already. So the plan is to dive into gphoto and use what I learned about the protocol to fix the gphoto support.

If you own some other WiFi-enabled Canon camera supported by the CameraWindow software, let me know.

Looking for hackers with the skills:

      I pushed my test program to https://github.com/michal42/wphoto. See the README file for instructions how to use it.

      I tried the Windows version of the CameraWindow software once more, but I still couln't get it working. The camera does discover the machine via UPnP, but it does not proceed further. It probably should continue by transfering the images via PTP/IP, because the camera opens port 15740 in this mode. But it's not working for some reason, so I'll continue with implementing the IMINK protocol used to share images with phones.

      I'm writing a gphoto2 camlib driver. Today, I ported the upnp handshake in it. It works if the imink.pl script is started in parallel. Now I'm going to implement filelist and file download in the camlib driver.

      I'm going to skip the file receive feature (i.e. transfer initiated by the camera) for now, because gphoto2 has no api for this mode of operation.

      Hi, is this still a Hackweek project for 2015? If so, I'd love to learn... and maybe join.... first time...

      It's still a hackweek project for 2015, I have the camera on my desk :). Are you still interested? I missed the comment, because I received no email notification...

      I got filelists (gphoto2 --port upnp: -L) working. It's a bit slow if you have thousands of files on the camera.

      Hey, I've got a S110, know some C and am very interested in this feature. Is there any way I could help?

    ESETv2 Emulator / interpreter by m.crivellari

    Description

    ESETv2 is an intriguing challenge developed by ESET, available on their website under the "Challenge" menu. The challenge involves an "assembly-like" language and a Python compiler that generates .evm binary files.

    This is an example using one of their samples (it prints N Fibonacci numbers):

    .dataSize 0
    .code
    
    loadConst 0, r1 # first
    loadConst 1, r2 # second
    
    loadConst 1, r14 # loop helper
    
    consoleRead r3
    
    loop:
        jumpEqual end, r3, r15
    
        add r1, r2, r4
        mov r2, r1
        mov r4, r2
    
        consoleWrite r1
    
        sub r3, r14, r3
        jump loop
    end:
    hlt
    

    This language also supports multi-threading. It includes instructions such as createThread to start a new thread, joinThread to wait until a thread completes, and lock/unlock to facilitate synchronization between threads.

    Goals

    • create a full interpreter able to run all the available samples provided by ESET.
    • improve / optimize memory (eg. using bitfields where needed as well as avoid unnecessary memory allocations)

    Resources

    Achivements

    Project still not complete. Added lock / unlock instruction implementation but further debug is needed; there is a bug somewhere. Actually the code it works for almost all the examples in the samples folder. 1 of them is not yet runnable (due to a missing "write" opcode implementation), another will cause the bug to show up; still not investigated, anyhow.


    FizzBuzz OS by mssola

    Project Description

    FizzBuzz OS (or just fbos) is an idea I've had in order to better grasp the fundamentals of the low level of a RISC-V machine. In practice, I'd like to build a small Operating System kernel that is able to launch three processes: one that simply prints "Fizz", another that prints "Buzz", and the third which prints "FizzBuzz". These processes are unaware of each other and it's up to the kernel to schedule them by using the timer interrupts as given on openSBI (fizz on % 3 seconds, buzz on % 5 seconds, and fizzbuzz on % 15 seconds).

    This kernel provides just one system call, write, which allows any program to pass the string to be written into stdout.

    This project is free software and you can find it here.

    Goal for this Hackweek

    • Better understand the RISC-V SBI interface.
    • Better understand RISC-V in privileged mode.
    • Have fun.

    The project was a resounding success add-emoji Lots of learning, and the initial target was met.


    FastFileCheck work by pstivanin

    Description

    FastFileCheck is a high-performance, multithreaded file integrity checker for Linux. Designed for speed and efficiency, it utilizes parallel processing and a lightweight database to quickly hash and verify large volumes of files, ensuring their integrity over time.

    https://github.com/paolostivanin/FastFileCheck

    Goals

    • Release v1.0.0

    Design overwiew:

    • Main thread (producer): traverses directories and feeds the queue (one thread is more than enough for most use cases)
    • Dedicated consumer thread: manages queue and distributes work to threadpool
    • Worker threads: compute hashes in parallel

    This separation of concerns is efficient because:

    • Directory traversal is I/O bound and works well in a single thread
    • Queue management is centralized, preventing race conditions
    • Hash computation is CPU-intensive and properly parallelized


    Add a machine-readable output to dmidecode by jdelvare

    Description

    There have been repeated requests for a machine-friendly dmidecode output over the last decade. During Hack Week 19, 5 years ago, I prepared the code to support alternative output formats, but didn't have the time to go further. Last year, Jiri Hnidek from Red Hat Linux posted a proof-of-concept implementation to add JSON output support. This is a fairly large pull request which needs to be carefully reviewed and tested.

    Goals

    Review Jiri's work and provide constructive feedback. Merge the code if acceptable. Evaluate the costs and benefits of using a library such as json-c.
