Modifier functions. More of an experiment for now with syntactic sugar operators after an idea occurred:. Can Ruby define self infix operators and curry / procify them?.

QUESTION
If you compile two C programs that differ only in the return value, I'd expect the binary to differ only in the bits of this value. However, if I compile the following programs using GCC, dump the bits of the binary (using xxd) and diff the dumps, I get another difference.
Files return127.c ...ANSWER
Answered 2021-Jun-12 at 13:01What is the difference at the top?
It's build id difference. Install diffoscope
(or compare readelf --wide --notes
output from both libraries) and you'll nicely see:

I am asked to remove a country (China) from the dropdown menu of the plugin intl-tel-input
the code below displays the dropdown menu and it looks that it calls the utils.js file to retain the countries
...ANSWER
Answered 2021-Jun-11 at 12:14If you take a look at the intl-tel-input
documentation regarding Initialisation Options. There is an option called excludeCountries
.
We can modify your initialisation code to include this option to exclude China:

I was assigned to work with ten year old legacy Java project which generates the following artifacts.

Answered 2021-Jun-04 at 06:57I don't know the EAR artifact and Java, but as per Docker Docs, the ADD
command can extract .tar.gz
files but not .ear
file format, so I think it's better to have a Dockerfile
like this (see here for extract):

I have some test code that includes:
...ANSWER
Answered 2021-Jun-06 at 00:13I believe clang on most Linux distributions links with GNU libstdc++, whose support does indeed require libtbb. This is buried in the documentation, search for "Note 3". So you will have to install libtbb and add
-ltbb
to your link command.
QUESTION
I have dusted off an old LaTeX template that I used with RMarkdown some time ago (when it worked), updated to the latest R, RMarkdown, tinytex etc.
When I try to knit the document, it gives an error that it cannot find the Accanthis font:
! Package fontspec Error: The font "AccanthisADFStdNo3-Regular" cannot be (fontspec) found.
! name = AccanthisADFStdNo3-Regular, rootname = AccanthisADFStdNo3-Regular, pointsize =
! mktexmf: empty or non-existent rootfile! ...
This is called from the template with lines:
\usepackage{fontspec}
\setmainfont{AccanthisADFStdNo3}[ UprightFont = *-Regular, ItalicFont = *-Italic, BoldFont = *-Bold, BoldItalicFont = *-BoldItalic, Ligatures={TeX,NoRequired}, ]
TinyTex can see the font in that
tinytex::tlmgr_search("/AccanthisADFStdNo3-Regular[.](tfm|afm|mf|otf)")
locates an.otf file
but running from the command line
mktextfm AccanthisADFStdNo3-Regular
gives "mktexmf: empty or non-existent rootfile!" and is looking for a .mf file that does not exist.
Any idea what the cause of this is? Thanks
...ANSWER
Answered 2021-Jun-02 at 17:27It seems to require a file extension after the font name, which it didn't in the past.
I changed a line in the template to include .otf
QUESTION
I have two functions, both are similar to this:
...ANSWER
Answered 2021-Jun-01 at 18:57I question the following assumption:
This didn't work. It is clear that the compiler is optimising-out much of the code related to z completely! The code then fails to function properly (running far too fast), and the size of the compiled binary drops to about 50% or so.
Looking at https://gcc.godbolt.org/z/sKdz3h8oP, it seems like the loops are actually being performed, however, for whatever reason each z++

QUESTION
Although my question is related to a specific problem, I would like to approach it in more general terms. I would like to simplify a fractional complex expression obtained by multiplying symbolic matrices using the sympy package. What I get is a fraction with real parameters and many complex exponential terms (phase terms) like exp(-jd), exp(-2jd) and also exp(-4j*d). I get the correct result, but when I try to calculate the ||**2, which is a real expression, sympy.simplify() is not able to manage the phase terms and I obtain a huge expression I have to reduce by hand. My test procedure, being T, M, M_inv, F and T, 2x2 symbolic matrices is:
...ANSWER
Answered 2021-Jun-01 at 13:59A few points:
Don't mix up numpy and sympy like this unless you know exactly what you are doing. There is no need to use numpy at all here so use e.g.
sym.eye(2)
andsym.conjugate(val)
Don't use floats unless you have a good reason - use
sym.I
instead of1j
. Using numpy can potentially introduce floats so don't do that unless you know what you are doing.Although
eigenvals
returns a dict in this case you only care about the values of the dict so you can just dolist(M.eigenvals())
.Although you declare all symbols as real you are using
sqrt(u)
which is real only ifu
is positive. Unless you intend forsqrt(u)
to be potentially imaginary thenu
should be declared as positive.
With the above changes your code looks like this:
QUESTION
I have separated the code into files (*.c and *.h) and included them. I have guard headers and all the separated files were reported to being build:
...ANSWER
Answered 2021-May-30 at 07:57Sketch.cpp is compiled as as C++, including test.h. In order to support function overloading, class membership etc, C++ uses name mangling to encode these C++ features in the symbol name. As such the symbol name for some_test
in Sketch.cpp is not the same as that in test.c which is compiled as C and no name mabgling is applied..
The solution is to prevent name mangling for this symbol when the header is C++ compiled by specifying that the symbol has C linkage:
QUESTION
I am trying to learn Java WebStart following THIS TUTORIAL, but I am running into a ClassNotFoundException. I deployed my jar file to https://dalayach.github.io/TestClass.jar
Here is the stacktrace
...ANSWER
Answered 2021-May-30 at 03:23Apparently, my code wasn't wrong, but I was making and testing changes so quickly that I was making updates faster than Java WebStart could check for them.
This is because of the update policy I had above -- If you have as a setting in your
.jnlp
, you are telling Java WebStart to download the newest files lazily. This means that if you jump back and forth between different solutions rapidly, Java WebStart may literally be too slow to keep up, and have an out of date version by the time the old one finally comes in.
There are 1 of 2 solutions to choose from.
Change the update policy for
TestClass.jnlp
.- If you want Java WebStart to wait until all updates have downloaded before trying to run your application, you should change your update policy to be something like this -
. This way, you can guarantee that your jnlp is pulling the most recent files.
- If you want Java WebStart to wait until all updates have downloaded before trying to run your application, you should change your update policy to be something like this -
Use
javaws -uninstall
before each run of your application- This command clears the cache, so that your program needs to be redownloaded fresh. This is effectively the same result as the above bullet, but this allows you to keep your
.jnlp
file with the preferred settings. Plus, you don't have to keep switching it back and forth as you debug any settings. Simply clear the cache and test.
