If you want to see an example of a Play Framework 2.6 data entry form that that sets help text (tips or tooltips) on text input fields (Play inputText fields), here’s an example of the required syntax:
As shown in the image, I was just reminded that you can run
javap inside the Scala REPL. The REPL help command shows some other things you can do:
scala> :help All commands can be abbreviated, e.g., :he instead of :help. :edit <id>|<line> edit history :help [command] print this summary or command-specific help :history [num] show the history (optional num is commands to show) :h? <string> search the history :imports [name name ...] show import history, identifying sources of names :implicits [-v] show the implicits in scope :javap <path|class> disassemble a file or class name :line <id>|<line> place line(s) at the end of history :load <path> interpret lines in a file :paste [-raw] [path] enter paste mode or paste a file :power enable power user mode :quit exit the interpreter :replay [options] reset the repl and replay all previous commands :require <path> add a jar to the classpath :reset [options] reset the repl to its initial state, forgetting all session entries :save <path> save replayable session to a file :sh <command line> run a shell command (result is implicitly => List[String]) :settings <options> update compiler options, if possible; see reset :silent disable/enable automatic printing of results :type [-v] <expr> display the type of an expression without evaluating it :kind [-v] <type> display the kind of a type. see also :help kind :warnings show the suppressed warnings from the most recent line which had any

This is a page from my book, “A Survival Guide for New Consultants”
“When you can do nothing, what can you do?”
As I’ve mentioned, you’re hired to be a consultant because you’re a problem-solver, so it really hurts when you can’t help a client. It’s a tough lesson, but it’s an important one:
Despite your best efforts,
you can’t always save the client.

I'm trying not to swear in this diary, but I hate coming to this #!@% office -- and this is supposed to be my company. Every time I come back to the office there's another project falling apart, or infighting between different groups that I have to work out. A few weeks ago when I was heading out the door for a sales call there was something that had to be done that "only I could do", and I had to run late to that meeting, and again today there were several more near-disasters, and everyone pounced on me before I could set my laptop bag down.
As a note to self, when you’re writing an Android application and you think you want to store some static text in an external file, a better approach can be to create a resource file under res/values.
For example, I’m currently adding some help text to an Android app, and to do that I created a file named strings_help.xml under the res/values directory. That file contains HTML wrapped in an XML CDATA tag, like this:
It took me a few minutes to figure out that when you want help on Play Framework console commands (i.e., the Play command line tool), you may get more useful help by typing
help play instead of just
help. Using the first command shows information on commands like
console, etc., which is what I'm more interested in.
To take a quick look at this, here's what you get when you type
I just started using tmux last week, and created a cheat sheet to help me remember the basic
tmux commands, and I thought I'd share that here.
The cheat sheet has a few things that are specific to my configuration file, so to begin with, here is my ~/.tmux.conf file:
I just ran into the craziest problem where I couldn't get any third-party apps on my iPad to open. I'd tap them, there'd be a quick blink, then nothing, I was back to the home screen with all my app icons.
