    I need complete and minimal system image for test my app. Linux embedded OS should only have the files required by my Qt5 application (the necessary libraries maybe you can find them with the command ldd. All the necessary libraries can be installed with openembedded .ipk files WITH OPKG COMMAND). Basically my Qt5 application requires: OpenGL ES (Is good to include gles3 library) Marble library (there was no problem in adding it) SQlite 3 Data Base (there was no problem in adding it) Transparences in windows and buttons (configure composer) Qt5 library QSerialBus for canbus communication Hide text (or show image) at start or shutdown Fast Boot and hide text in boot and shutdown or change by picture. Customized toolchain BaseBoard: Toradex Ixora V1.1 CoreBoard: Toradex Apalis IMX6Quad 2GB v1.1 The system should be minimal (Pocky or reduce Armstrong. You must evaluate it). Remove games, qt examples, files not required, Internet navigator, video player, desktop, etc. Only need run my app in fullscreen. My application should start from the beginning. You can see the startup scripts in the existing images by teamviewer. Currently I have an image that only needs to add QserialBus, transparencies in windows (composer) and be minimal. I have the summarized steps to create this image. I need all toradex drivers and the update system that includes the yocto package. You must write all steps in document.

    My name is Bernard, I am trying to polish the user experience of an existing juce project that I have by improving the visual feedback the UI is providing. I need a vectroscope for the audio unit. It would be nice if we could improve the existing code too since I pretty much took a "learn as I go" approach to my code base and the current state of my code organization skills could use some improvement by people who actually know how to code.

    I WANT A BITCOIN EXCHANGE. IS AN EXCHANGE FOR BITCOINS IN BRAZIL, IN THIS FIRST MOMENT I DONT NEED ANOTHERS COINS, IT WILL BE AN UPGRADE. FOR NOW, JUST BITCOIN. I WANT TO FOLOW EXACTLY THE WEBSITE IN BRAZIL (.[url removed, login to view]) CALLED BITCOINTRADE. PLEASE, GOOGLE IT BEFORE MAKE ME A PROPOSAL. Any exchange software should have these 4 different components working together: 1. The first component is the trade engine. The trade engine should be the core of any exchange. It accesses the order book, matches buy/sell orders, executes transactions and calculates balances. Without a trade engine, your exchange cannot function. So make sure you have a working trade engine before setting up anything else, or otherwise you will merely have an empty shell. 2. The second component is the user interface (UI) or front end of the exchange website. The user interface is how your traders see your exchange (e.g. trading platform and the design of your website). Any user interface must be user friendly and intuitive. This may sound cheesy, but make it your goal to offer your customers a wonderful trading experience (Tipp: less is more). The UI needs to be mobile friendly too, as the use of smartphones is constantly increasing. A dedicated app for mobile devices would make the exchange more easily accessible which in turn may enhance trading engagements. Ideally, the UI should enable the user to Register and access an account Deposit, maintain and withdraw Crypto and Fiat currencies View current order book, past transactions, balances, statistics etc. View charts Place buy and sell orders Access the support mechanism 3. The third component is the wallet. The wallet is the bitcoin daemon running on the exchange server. This is where the bitcoins (of the exchange operator and his traders) are stored, hence it needs maximum security. Any exchange should implement a so-called hot/cold wallet system to diversify risk. The hot wallet is the bitcoin gateway of the exchange and allows the customer to instantly withdraw bitcoins to their external wallet without the need of approval from an exchange operator. A hot wallet need to have a positive balance for instant withdrawals which can be set according to the turnover of the exchange. A cold storage wallet is where rest of your bitcoins are stored. This wallet is completely offline which guarantees that nobody can access your leftover bitcoin even if your hot wallet is hacked (Therefore, it is advisable to always put aside a certain amount of bitcoins and leave them in your cold storage wallet.). A simple cold storage wallet could be a piece of paper or an USB stick where your private keys are located. Splitting the bitcoins into hot/cold wallet system provides a perfect balance between security and convenience for instant withdrawals. Bitcoin Wallet 4. The fourth component any exchange should possess, is an admin panel. The admin panel of an exchange is the equivalent of business intelligence and management software. It helps the exchange operator control and manage his exchange. Functions should include: Altering liquidityAdmin Panel Bitcoin Exchange Software Editing the spread and trading fees Approving user accounts for trading, after verifying KYC or other compliance requirements Managing currencies like BTC, USD, ETH, etc. and markets like USD/BTC, BTC/ETH, etc. Crediting fiat deposits, or debiting fiat withdrawals requested by users Addressing the support requests raised by users In summary, these four components, the trade engine, the user interface, the wallet and admin panel should form the basis of any exchange software (Software engineers call this architecture of splitting your software micro-services).

    Hi, I'm looking to create a fairly simple program with a GUI. Right now I am running a program (FI Tools) through batch scripts / the command line, but this program is going to have be ran by less technically-inclined users, so we are looking to make the process more user-friendly. Right now the batch file looks like this: @echo off cd C:Program Files (x86)FID3 fiwdir **target_directory** **parameters** >**output_directory[url removed, login to view]** From what I have thought of myself, the program should: -Check that FI Tools is installed -Ask the user for the target directory, this may or may not include subfolders -Default to a list of parameters -Ask the user for an output directory -Ask the user for the output filename (it should be outputting .csv files) -Have an "Customize" option that allows the user to modify the parameters -If this is done by creating and running .bat files it should delete them after they are ran. If you have any questions please feel free to ask.

    Nowadays fitness studio owners have recognized the importance of a highly equipped room for group fitness classes. Most of them have a special floor, powerful music, small stage, etc. However, most of the studios do not have yet a professional lighting system. It is common that music based group fitness formats (e.g. Zumba, Pilates, Yoga, HIIT, Bodypump, etc.) are taught with plain “cleaning” light without any atmosphere. We want to change that! However, it is not sufficient to solely sell a lighting system with a simple automated sound control. We rather want to offer a system that supports a customized light show for each random song that any fitness instructor is playing. Each fitness studio has various fitness instructors (in average 20 or even more). Each of them uses different songs. Sometimes an instructor changes its playlist by adding a new song. We need a Software that accommodates the following tasks: 1. The fitness instructor connects his smartphone with the computer (rack) via analog audio jack plug and plays the music. 2. The analog audio signal will be analyzed and the title of the song will be immediately be identified by the music recognition software (e.g. Gracenote API). 3. Shortly after identification the Software shall load the matching DMX control file from local HD. 4. The DMX control files that executes the light shows are programmed and customized to a specific song beforehand on a remote PC with a commercial or open source DMX control software. These newly created DMX control files will be send and saved on the computer (rack) that is located in the fitness studio. There are some DMX control software solutions with an API or SDK (e.g. DMXControl3, grandMA2, SUSHI-DS). 5. As soon as DMX control files is loaded and ready to be executed some seconds are already elapsed. In order to avoid any time delays there needs to be a synchronisation to ensure that the light show is matching with the song. Until the synchronisation the lighting system shall work with an automated sound control. 6. Finally, the DMX signal will be send out per the DMX output interface. 7. In case there is a new song played by an instructor the Software shall send a message to the remote PC. 8. The Software shall also have a memory- or scheduling function. The Software shall be able to memorize the playlist of each class/instructor plus weekdays and times of the classes. Thus, the playlist will be anticipated and the matching DMX file with each song will be loaded even faster.
