This gem is a tool you can use while developing your API to help consumers of your code to find bugs earlier and faster. It works like this: any time you write a method that could produce nil, you instead write a method that produces a wrapped value.

QUESTION
This code receives information from an acquaintance you want to register in editText, and then clicks finButton to save the information you receive as a file called friendlist.txt. However, the Toast message is outputted from the try-catch statement that is currently performed when finButton is pressed. Also, the checkpermission does not work, which is wrapped in a try~catch statement, but does not have output on the logcat.
And manifest.
uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"
uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"
is written.
Please let me know the solution. And this content is written with a translator, so the sentence can be strange.
when you press finButton, the logcat is shown below.
The code corresponding to the 116th line is this.
...FileOutputStream outstream = openFileOutput("friendList.txt", Activity.MODE_WORLD_WRITEABLE);

QUESTION
When I hover over the anchor tag, it flickers. It's because there are vertical gaps between the lines of the wrapped anchor tag. Moreover, if I happen to click between the lines, the link doesn't activate. I would like to get rid of this flickering and vertical hover gaps that cause it. The rest of the layout including apparent line height and button position (on the same line as the last word of the anchor tag) should stay the same.
I was thinking about this for a couple of days with no luck. The best alternative I have is using inline-block on the anchor tag, but that clears the button to the next line, which wastes too much space.

QUESTION
I have to parse lists of names, addresses, etc. that were OCRed and have invalid/incorrect characters in them and on the state postal code I need to recognize the pattern with a 2 character state followed by a 5 digit postal code and replace any non numeric characters in the postal code. I might have OK 7-41.03
at the end of a string I need to remove the hyphen and period. I know that re.sub('[^0-9]+', '', '7-41.03')
will remove the desired characters but I need it only replace characters in numbers when found at the end of the string and only if preceded by a two character state wrapped in spaces like OK
. It seems if I add anything to the regular expression as far as a lookbehind expression then I can't seem to get the characters replaced. I've come up with the following but I think there must be a simpler expression to accomplish this. Example:

I’m using R to prepare data to input into a model (written in Fortran, compiled into an .exe).
The model requires a text file as input which I'm generating using R. In the end it’s mostly just a list of variables (like ‘VARIABLE_X = 0.6’). The value of these variables is based on some processing I'm doing in R. An example on how the generated text file partly looks like;

QUESTION
I have a function of type 'state -> 'event -> Result<'state * 'result, 'error>
. I have a starting 'state
and 'event list
.
I'd like to fold over the events and get the final state and list of results produced if all folds were okay, or the first error.
I could write a computation expression or fold for it, but was wondering if there was a name for this pattern? Is there something I could use out-of-the-box from FSharpPlus? It seems close to a state monad, but the state and result are both wrapped inside a Result
type, so it's sort of a state + result monad?
ANSWER
Answered 2021-Jun-14 at 15:20As @carsten already pointed, you have StateT
available in F#+
You have:
'state -> 'event -> Result<'state * 'result, 'error>
Now let's swap some parameters:
'event -> 'state -> Result<'result * 'state, 'error>
this can be expressed as
StateT<'state, Result<'result * 'state, 'error>
in current F#+ StateT encoding.
So, let's call your function f
and let's pretend you have events
which is an list<'event>
(or actually any other traversable structure of events) , now you can do this:
QUESTION
so basically I've been experimenting with CSS recently and I came across something which looked seemed new to me. I usually use units such as em, or px when setting the padding of an element but this time I tried using percentages and to my surprise it worked very differently than the other units.
So I set up three different situations:
...ANSWER
Answered 2021-Jun-13 at 19:14If you specify the width of a div as a percentage, it refers to the percentage of the divs parent's computed width, when you specify viewport it refers to percentage of the window screen. Pixels on other-hand are absolute unit they are not relative like percentage. That is the primary reason percentage acts differently with flexbox and not just flexbox but with everything. See some of this articles for reference: https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Values_and_Units https://developer.mozilla.org/en-US/docs/Web/CSS/percentage

Install wrapped
On a UNIX-like operating system, using your system’s package manager is easiest. However, the packaged Ruby version may not be the newest one. There is also an installer for Windows. Managers help you to switch between multiple Ruby versions on your system. Installers can be used to install a specific or multiple Ruby versions. Please refer ruby-lang.org for more information.
