Ionide's codelens in F# doesn't show (vscode) - f#

After reinstalling my Mac, codeLens doesn't work all of a sudden.
I'm using vscode for mac with the ionide-fsharp extension installed. Usually it was enough to have CodeLens active, where I'd see the signatures above my code.
The "int" above "let a = 5" is what I was used to be using, and it was such a pleasant feature.

Visual Studio for Mac won't update - Xamarin

Weird issue here. I have Visual Studio for Mac. My mac is fully upto date on the mac sidel. I have updated to Xcode 12.5. I have selected the check for updates option in VSMac. I see that there are a bunch of updates for xamarin on my mac. I selected for it to update and restart, and then nothing happens. VSMac just closes. I'm assuming I have something on my system that VSMac doesn't like. Is there a way to just get the downloads and manually install them?
Here was the way that I solved the problem. I went and downloaded the various pieces that I knew I had specific problems with. This was VSMac, Xamarin.iOS, and Xamarin.Mac. I downloaded those, and then installed the iOS and Mac versions. Everything was still good. Then I installed the most up to date VSMac. It detected the old versions of Mono, Android, and some other stuff, and downloaded and installed them. Now, my current problem is solved. There may still be others, but this got my immediate problem resolved.
Hopefully, this helps someone else in the future.

Working on F# compiler source code on a Mac

I would like to open F# compiler solution (FSharp.sln) from https://github.com/fsharp/fsharp/ in an IDE on a mac, then make some changes and run the compiler or ideally step through the code.
I tried JetBrains Rider, but it gets stuck soon after opening the solution: "Initial file processing: prim-type-prelude.fs". Code completion is not available.
I also tried opening another solution from https://github.com/Microsoft/visualfsharp, but both Rider and Visual Studio For Mac crash almost immediately.
What's the best way of working on F# compiler source code on a Mac? Is this feasible only on Windows? I'm new to .net and F#.
Edit: I had much better luck with Windows and Visual Studio. Everything worked pretty much out of the box. I was able to run the project, debug selected test and make minor changes with code completion enabled. I might be missing something, but it seems like it's a much smoother experience on Windows than on a Mac.

Trouble getting started with Lua

I wanted to learn Lua so I bought a book. The problem I'm having is finding a compiler/interpreter. I downloaded the binary compiler for Windows from http://luadist.org/ (Windows x86 (MinGW32 4.7.1)). But every time I try to start it up I just says:
The program can't start because lua53.dll is missing from your
computer. Try reinstalling the program to fix this problem.
Which I did several times to no avail. I've tried to find another compiler but this seems to be the only one... which I find hard to believe. There are "demo" compilers but I want one I can install so I can do the examples in the book. There are instructions on how to "compile" the compiler at the Lua site on Linux and Mac machines but I'm working on a Windows machine.
Any help?
ZeroBrane Studio is the best for Lua. It works on Windows, Mac, and Linux. It was specifically designed for beginners, but it a full featured IDE for writing and debugging Lua code.

Be sure to try the "Run as Scratchpad" feature which provides a "live-coding" experience.

Brother Label Printer SDK bPac 3.1 Failed to print

I've got the printer driver, P-touch Editor, b-PAC 3.1 and client tools, all 64-bit, downloaded from the Brother website and installed on my 64-bit Windows 7 laptop. The P-touch Editor works/prints fine.
However, b-PAC failed, and none of the samples worked. I debugged the code:
bool b = doc.PrintOut(1, bpac.PrintOptionConstants.bpoDefault);
where b is false. What could be wrong?
I was hitting the same problem, everything appears to work right up to the point where I called "PrintOut", which fails with error 11, "The currently specified printer is not supported".
It turns out the problem I had was with the driver. I had installed the printer driver from the CDROM that came with the label printer. Windows 7 also comes with an "in-box" driver for the printer and in fact this is the one you should install (it's marked with an "LE" at the end).
To fix the problem, all you need to do is go to the "Devices and Printers" dialog, select the printer, right click on it and select "Printer properties", select the "Advanced" tab and click "New Driver". Find the printer in the list that matches yours but with an "LE" at the end and click OK.
Printing is possible with either of the drivers using the P-Touch editor. Odd thing is, "LE" appears to stand for "Light Edition", but the "Heavy" version doesn't work!... strange.
On my Windows 10 x64 machine, I've had a similar issue using Ruby to print through the bPAC SDK (using win32ole). My code worked on another machine, but not mine.
After fighting with this for a long time, I figured out that all was fine and dandy when using the 32 bit version of the bPAC SDK (and Ruby). Don't know exactly what went wrong here, but it might be that the 64bit SDK is just broken.
I had a similar problem, so I added this after the printOut to see which code I was getting.
string sError = doc.ErrorCode
It returned Error 11, which corresponds to "Device is not supported", but the device was a QL-570 which IS supported.
To get it working, I used the following steps:
Side-install the 32bits sdk.
Open your 64bit sample.
Change target configuration platform from "any cpu" to "x86"
Compile
See also: Label printing development using b-pac SDK in a C# application
The important thing is the application that you uses.
If your app is a 32bitapp (inclusive excel) you need the bPAC SDK for 32bit even when they are running on 64-bit Windows OS.
Some printers only support 32-bit b-PAC SDK ver.
(even if you use windows 10 64-bit with Excel 64-bit)
please check:
https://support.brother.com/g/s/es/dev/en/bpac/environment/index.html
I had the same problem (printOut gave me the error code 11).
The error appeared after switching from the printer PT-9800 to PT-P950.
Trying 32 and 64bit did not work for me.
What fixed it was uninstalling the driver of the PT-9800. I found a hint in the b-PAC 3.4 SDK Help in the section Troubleshooting: "if the old label printer will no longer be used, we recommend deleting the printer driver."

Memory Load/Save Utility in Code Composer 3.3

Apologies in advance for the dated software question:
According to Code Composer help documentation the "Memory Load/Save Utility" should be be in the Tools menu. In my Code Composer 3.3 (which I have to use for this project, so I cannot upgrade), does not have this option in the tools menu, or any menu that I could find. It is not greyed out - it is just simply missing as far as I can tell. I've changed every view option to try and enable this.
Can anyone help me figure out how to enable/activate this option? Does the processor need to be in a specific state? Is this a special plug-in that I can't find?
Here is my setup:
Code Composer 3.3, Windows Xp, Using a Spectrum Digital xds510pp JTAG emulator on a TI ARM 9 processor.
Specifically the option is here: 13. Memory Load/Save Utility:
http://www.ti.com/lit/an/spraa07c/spraa07c.pdf
[EDIT] The File > Data > Save - this is not the same as the Memory Load/Save Utility. This sounds similar but does not export the values.
For example, I need to export data at a certain memory address for a certain length into a hex format.
Somehow my installation went bad.
I checked the Code Composer Studio Component Manager by running C:\CodeComposer3.3\cc\bin\comp_mgr.exe. Now, in this window un the TI node, there should be numerous plugins and one of which should be: "Memory Save/Load Utility Control..."
For me this was missing.
Repairing the installation via windows control panel did not work. I had to uninstall and then reinstalled. Upon reinstalling a TMS470 driver was reported missing. Not sure why this was.
Again, I uninstalled then complete removed the C:\CodeComposer3.3\ directory, then reinstalled. This time everything seemed to have worked and I do have the Memory Save/Load Utility and it is working.
EDIT:
It should also be noted that the plugins are bundled with the installer and could not be re installed separately.
