boogie | A little programming language written in Go

I am trying to release an electron app on the Mac Apple Store (mas), my electron app uses ffmpeg to render videos. In order to release my app on the mac apple store, It needs to be sandboxed, and by default ffmpeg makes calls to external libraries so I need to statically build ffmpeg and package it with my app. My code is on the 'mas-ffmpeg-fix' branch: https://github.com/MartinBarker/digify/tree/mas-ffmpeg-fix

My static ffmpeg build works before I build my app, but after running electron-builder build --mac, the ffmpeg executable now fails with Illegal instruction: 4

This is the full timeline of building/packaging/submitting my app to the mac apple store and where the error first appears:

• In Digify repo:

• clone, configure, and build static ffpmeg: “sudo rm -rf ffmpeg-mac/ && npm run download-ffmpeg”

• download-ffmpeg command is inside package.json and runs this: git clone https://git.ffmpeg.org/ffmpeg.git ffmpeg-mac && cd ffmpeg-mac && ./configure pkg_config='pkg-config --static' --pkg-config-flags='--static' --libdir=/usr/local/lib --extra-version=ntd_20150128 --disable-shared --disable-lzma --enable-gpl --enable-pthreads --enable-nonfree --enable-libass --enable-libfdk-aac --enable-libmp3lame --enable-libx264 --enable-static --enable-filters --enable-runtime-cpudetect && make && cd ..

• Check if any dylibb files in the static ffmpeg build with command: “otool -L ffmpeg-mac/ffmpeg | grep /usr/local”

• If there are any, move them to folder in desktop, run ‘otool’ again to ensure there are no dynamic libraries, rebuild static ffmpeg.

• there will now be a folder 'ffmpeg-mac' which contains static versions of ffmpeg and ffprobe

Using ffmpeg with electron UI: works Using Ffmpeg with command-line command: /Users/martinbarker/Documents/projects/digify-new/ffmpeg-mac/ffmpeg -h Works

• Build mac mass app with “npm run build-mas“
• When this command finishes it will output two files inside the /dist/mas/ folder: Digify.app and Digify-01.20.pkg (or whatever version number it is) Ffmpeg command-line check: /Users/martinbarker/Documents/projects/digify-new/dist/mas/Digify.app/Contents/Resources/ffmpeg -h Illegal instruction: 4

This is the first place the error appears, after building my mac mac-apple-store app, ffmpeg fails with this err.

• Sign built app with .sh file: “sh mas-sign-script.sh” view .sh file here
  • the .sh file will output Digify-mac.pkg
• Easier command to both build & sign: “sudo rm -rf dist/mas/ && npm run build-mas && sh mas-sign-script.sh”
• Upload the outputted “Digify-mac.pkg” file & submit to apple for review

Once this app gets published in the store, if you download it and try to run an ffmpeg command with the electron UI, it fails with this error:

I am using Next JS with Apollo and I hve the following query that works just fine, but when I navigate away from the page to another page and back the query doesn't run my fields are empty and I have to hit refresh to populate them. Does anyone know why this may be.

I am trying to compare two filepaths. I receive the filepath from a db query, and I need to find in the .m3u file for a match I have the following code which is not working properly. If the two filepaths are a match, then return the index from the $contents array as a pointer.

I've got some XML inputs that I convert to PHP arrays using LaLit's XML2Array.

So, the goal of this project was to scrape the results of the top 100 list, query a database to see if those titles were within it, and return back information of all top 100 songs not contained within said database. The datasets are as follows:

I've been trying to parse a dictionary, which is returned by a database I'm working on, but I'm not sure about the best approach to take. I think the difficulty is being caused by the fact that the list sizes within the dictionary are not symmetrical, so my approach doesn't seem to be able to pull out what I'm looking for.

The data structure looks like this:

As mentioned in the Wiki on Dafny GitHub, when Dafny cannot prove an assertion in a program, it might be due to either my program is incorrect OR the incompleteness of Dafny. But I figured the counter example from Dafny is spurious after I tried understanding it, so I still have no idea if my program is correct or not.

My question is as follows. If I manage to use another Boogie backend such as Corral to check the translated Boogie program from Dafny using /print, and Corral also returns a model to invalidate the Boogie program, would that guarantee the model disprove my Dafny program and I can use it for debugging? Or is it still likely spurious so don't bother to try it?

From their papers, it seems to me that Corral and Symbooglix should guarantee that a provided model should be a concrete counter example for the translated Boogie program, so maybe my question is more on whether the Dafny program and the translated Boogie program is semantically equivalent.

PS: I tried passing translated bpl files to Corral and check specific Boogie procedure in that bpl, and Corral simply says it cannot find the procedure, so I'm debating if I want to make it work.

I'm working with a large csv file that contains songs and their ownershp properties. Each song record is written top-down, with associated writer and publisher names below each title. So a given song may comprise of say, 4-6 rows, depending on how many writers/publishers control it (example with header row below):

I would like to prove this:
