debugging

问题 So bear with me as I am very new to coding. I'm trying to compile a Fortran file but I keep getting this issue in my terminal. I am using GNU Fortran (GCC) 9.2.0 and I believe I have all other prerequisites updated Xcode and atom.

问题 I have a card-element (bootstrap-4) with a front and back, on hover the back side is shown. In order to create a "folded corner effect" I am using a pseudo-element(:before) on the front card, which works fine for all browsers except of firefox. The bottom-left corner of the pseudo-element should also be rounded, so I set a border-radius. Unfortunately in Firefox the corner is not rounded, instead there is a strange box shown in the pseudo-element. Any ideas what is causing this issue in

问题 I am trying to define a chain of commands, which shall be invoked after a breakpoint in gdb: break some_function commands up next printf "some_string" continue end In this case (for example) I want to break at some_function, go up in the stack frame and jump right behind this function via the next command, then print "some_string" (or maybe some variable, which was changed by the function) and then just to continue. But that doesn't work, since gdb will just stop after the next command and

Basically what I had to do is add following to build.gradle file according to the link they show. android.buildTypes.release.ndk.debugSymbolLevel = { SYMBOL_TABLE | FULL } I assume it is android/app

问题 Basically I am practicing NodeJs/MongoDB by making a simple blog app. I am using the .find() method to final all the saved blogs on the db , and then running it through a loop to post it on the main page. That method is called every time the page is refreshed, so how do I stop it from being called to avoid automatic reposts? exports.getBlogEntries = function() { Entry.find(function(err, entries) { if (!err){ for(i = 1; i < entries.length; i++ ) { list.push(entries[i]); } } }); return list; };
