kandi X-RAY | vi Summary

vi is a C library typically used in Networking, TCP applications. vi has no bugs, it has no vulnerabilities and it has low support. However vi has a Non-SPDX License. You can download it from GitHub.

This implementation is derived from ex/vi 3.7 of 6/7/85 and the BSD termcap library, originally from the 2.11BSD distribution. All of them were changed to compile and run on newer POSIX compatible Unix systems. Support for international character sets was added, including support for multibyte locales (based on UTF-8 or East Asian encodings), and some changes were made to get closer to the POSIX.2 guidelines for ex and vi. Some issues that were clearly bugs and not features have also been resolved; see the Changes file for details. New releases are announced on Freshmeat.

Vuejs Webpack Compression Plugin not compressing

Asked 2022-Mar-28 at 12:53

I need help debugging Webpack's Compression Plugin.

SUMMARY OF PROBLEM

Goal is to enable asset compression and reduce my app's bundle size. Using the Brotli algorithm as the default, and gzip as a fallback for unsupported browsers.
I expected a content-encoding field within an asset's Response Headers. Instead, they're loaded without the field. I used the Chrome dev tools' network tab to confirm this. For context, see the following snippet:
No errors show in my browser or IDE when running locally.

WHAT I TRIED

Using different implementations for the compression plugin. See below list of approaches:

Answered 2021-Sep-30 at 14:59

It's not clear which server is serving up these assets. If it's Express, looking at the screenshot with the header X-Powered-By, https://github.com/expressjs/compression/issues/71 shows that Brotli support hasn't been added to Express yet.

There might be a way to just specify the header for content-encoding manually though.

Laravel Homestead - page stopped working ERR_ADDRESS_UNREACHABLE

Asked 2022-Mar-25 at 09:10

Took my laptop out of house for a couple of days, didn't even get to turn it on during that time. Came back, ready to keep fiddling with my project but the page stopped working all of a sudden. I started getting ERR_ADDRESS_UNREACHABLE in the browser.

I've uninstalled homestead box, vagrant, virtualbox, with restart after each, re installed everything, same issue.

I can not ping the 192.168.10.10 address but I can SSH into the box no problem.

Running MacOS Big Sur, VirtualBox 6.1, Vagrant 2.2.18 and whatever the latest homestead version is. Really about quit programming altogether, this is super frustrating. I'd really appreciate any help. Thank you

QUESTION

Introduced intermediate variable in structured binding definition?

Asked 2022-Mar-19 at 13:13

In [dcl.struct.bind] 9.6.4, there is definition of structured binding when initializer is a class type with std::tuple_size::value properly defined:

... variables are introduced with unique names ri as follows:
S Ui ri = initializer ;
Each vi is the name of an lvalue of type Ti that refers to the object bound to ri; the referenced type is Ti.

My question is why is it necessary to introduce ri, can't we define the identifier vi directly as reference to the result of get(e)?

...

ANSWER

Answered 2022-Mar-19 at 11:43

The intent is to disallow redeclaring structured bindings as references. See CWG 2313.

QUESTION

Rearranging polygons in geopandas for matplotlib plotting

Asked 2022-Mar-08 at 20:20

I am working on a project where I am using a shape file to make a choropleth map of the United States. To do this, I downloaded the standard shape file here from the US Census Bureau. After a little bit of cleaning up (there were some extraneous island territories which I removed by changing the plot's axis limits), I was able to get the contiguous states to fit neatly within the bounds of the matplotlib figure. For reference, please see Edit 4 below.

Edit 1: I am using the cb_2018_us_state_500k.zip [3.2 MB] shape file.

The only problem now is that by setting axis limits I now am no longer able to view Alaska and Hawaii (as these are obviously cut out by restricting the axis limits). I would now like to add both of these polygons back in my map but now towards the lower part of the plot figure (the treatment that is given by most other maps of this type) despite its geographical inaccuracy.

To put this more concretely, I am interested in selecting the polygon shapes representing Alaska and Hawaii and moving them to the lower left hand side of my figure. Is this something that would be possible?

I can create a Boolean mask using:

You could do something like this. You will have to find the right offsets to position Alaska where you want it to be exactly.

Optimize Union Find (Disjoint Set Union) implementation

Asked 2022-Feb-08 at 13:18

I have implemented a Disjoint Set Union in C++ for a Kattis problem. However, my solution is inefficient, as I get TLA (Time Limit Exceeded) for the first hidden test case. Can anyone spot an inefficiency with my code?

I have based my implementation on this article. In particular, I set the parent of the parent of the smaller set to the parent of the bigger set (when making an union of the sets). According to the mentioned article, this should be as efficient as using the rank:

Both optimizations are equivalent in terms of time and space complexity. So in practice you can use any of them.

...

ANSWER

Answered 2022-Feb-08 at 01:21

This seems to be a Kattis-specific IO problem. Adding ios::sync_with_stdio(false); cin.tie(NULL); cout.tie(NULL); to the start of main, and changing both occurrences of endl to '\n' causes it to pass in .2 seconds.

I'll also mention that including is frowned upon here, but the only cause of your error was the IO. Your implementation of Union Find is correct and runs in the standard inverse Ackermann time bounds.

Signature from the styled API Documentation:
styled(Component, [options])(styles) => Component

The props are passed into the styles parameter (from where you're also destructuring and retrieving theme), so you can add your open property to that and use it directly -- for example:

Install vi

First look at the Makefile and change the settings there to match your build environment. Explanations are provided directly in this file. You can tune the sizes of some internal buffers by editing config.h. Then type make and make install. It is possible to build a RPM file directly from the source distribution by executing. Note that the RPM spec installs the binary in /usr/5bin by default to avoid conflicts with vendor files in /usr/bin. The default locations match those of the Heirloom Toolchest http://heirloom.sourceforge.net.
The system must provide an ANSI C-89 compiler and POSIX.1-1990 functions.
The system must provide an sbrk() call to increase the memory heap size. If only a fake sbrk() call is provided that works by pre-allocating several MB, vi will probably work too.
The system library must allow replacement of malloc() and printf() by the versions provided by vi. For malloc(), it also must make its own internal memory requests using the vi malloc(). Otherwise, vi will likely die with a segmentation fault because the storage allocated by sbrk() interferes with usual Unix library implementations of malloc().

Support

Support for multibyte locales has been added to vi. It requires a number of functions that, while specified in XPG6, are not present on all systems that provide basic multibyte support. In particular, vi needs wcwidth() to determine the visual width of a character, and mbrtowc() to detect when a byte sequence that is entered at the terminal has been completed.
