+====== Carrier Reset for HTC One M8 on Sprint ======
+I was getting a "Unable to establish a wireless data connection" error on my HTC One M8 on Ting using Sprint's network. The technician suggested calling ''##72786#''' to do a "Carrier Reset". It retried to activate several times unsuccessfully, but on the last attempt I stepped outside and then it succeeded. Since then my mobile data connection seems to work fine again.

+</code>
+====== KDE Plasma Task Manager button width ======
+When turning on Group by Program name but turning off Combine into a single button, the maximum task manager button size decreases.
+I fixed this by editing preferredMaxWidth() in ''/usr/share/plasma/plasmoids/org.kde.plasma.taskmanager/contents/ui/code/layout.js'':
+<code javascript>
+function preferredMaxWidth() {
+    if (tasks.iconsOnly) {
+        if (tasks.vertical) {
+            return tasks.width + verticalMargins();
+        } else {
+            return tasks.height + horizontalMargins();
+        }
+    }
+//    if (plasmoid.configuration.groupingStrategy != 0 && !plasmoid.configuration.groupPopups) {
+//        return preferredMinWidth();
+//    }
+    return Math.floor(preferredMinWidth() * 1.6);
+}

+plasmashell can be restarted to see the change take effect with:
