Answer : I don't know if paid software can be recommended, but after testing a lot of free tools, I finally decided to go for Beyond Compare. Meld was my previous choice but abandonned it due to instabilities during merging of very large folders. There are plenty of tools for this, here are a few with a GUI: xxdiff Meld * beediff KDiff3 * Diffuse * fldiff * They all do pretty much the same thing, but the first two possibly offer the best user experience. Those with an asterisk are available from the Software Centre. If you like Winmerge very much and would like to continue to use it in Ubuntu like me, you can do that by using Wine Windows Program loader to install Winmerge and run the program. It runs very well for me. I find none of the above GUI tools that come with Ubuntu to be as good as Winmerge. Maybe I am too biased for Winmerge :-)

Answer : This question is already answered, but I feel to clear something here in this topic. Most comments and answeres point out to use super.onBackPressed() and that this is the cause of the not working method onBackPressed() . But that is not correct and important to let other beginners know. The method onBackPressed() does not need to use super.onBackPressed() . onBackPressed() also works if somebody, for example, comment super.onBackPressed() out. As the questionier has written, he won´t use super.onBackPressed() because it will close the activity. So, the cause of this why it isn´t working, could be seperated into three possible causes: The Log doesn´t work because of a wrong filter in the logcat console The Toast dosn´t work because of the wrong passed context The OS is implemented wrong by the supplier. Usually, the toast works by passing the correct context. In the case of questioner, simply passing this . @Override public void onBackPressed() { Log.d

Answer : While not solving your problem directly, you should be able to install the library using the excellent unofficial Windows binary reposistory here: http://www.lfd.uci.edu/~gohlke/pythonlibs/#python-levenshtein Download the .whl file and install it using pip: pip install python_Levenshtein-0.12.0-cp35-none-win_amd64.whl As for the error, I agree with Rogalski. You likely need a C compiler installed (like the free Visual Studio Community Edition). Edit: Sorry, I just noticed that this has already been suggested in one of your linked questions here: https://stackoverflow.com/a/29926192/6345502 - I hope it helps anyway! Had a similar issue, solved by installing another related library: python-Levenshtein-wheels ; pip install python-Levenshtein-wheels In case you are using Anaconda, try: conda install -c conda-forge python-levenshtein

Example 1: figure centering latex \begin { figure } \centering . . . ( Code for pictures , captions ) . . . \end { figure } Example 2: center image latex \begin { center } \includegraphics { yourimage } \end { center } Example 3: Start Image from top of page Latex I assume you issue a \clearpage ( or something similar ) just before using \begin { figure } . . . \end { figure } , right ? If this is the case , add \mbox { } ( or \ null ) after the figure environment before starting a new \chapter and your alignment should be fixed . Since there's nothing else on the page , LaTeX centres it , since that would be the best way to present the information .

Example: angstrom unit of measure latex $\mathring{A}$

Example: print double in c # include <stdio.h> int main ( ) { double d = 123.32445 ; //using %f format specifier printf ( "Value of d = %f\n" , d ) ; //using %lf format specifier printf ( "Value of d = %lf\n" , d ) ; return 0 ; }

Answer : You can try this: myDropzone.on("complete", function(file) { myDropzone.removeFile(file); }); More information here: http://www.dropzonejs.com/#dropzone-methods removeAllFiles() and removeFile() will trigger the server-side removal too, if you hooked Dropzone to remove files as well. The solution to clear it only client-side, remove the file preview, and if you had a blank state message, remove the dz-started class to prevent the Dropzone CSS from hiding it: $('.dropzone')[0].dropzone.files.forEach(function(file) { file.previewElement.remove(); }); $('.dropzone').removeClass('dz-started'); Another option (similar to answer of Giraldi, but then when all files are completed): myDropzone.on("queuecomplete", function () { this.removeAllFiles(); });

Answer : From RFC 5321, section 2.3.11: The standard mailbox naming convention is defined to be "local-part@domain"; contemporary usage permits a much broader set of applications than simple "user names". Consequently, and due to a long history of problems when intermediate hosts have attempted to optimize transport by modifying them, the local-part MUST be interpreted and assigned semantics only by the host specified in the domain part of the address. So yes, the part before the "@" could be case-sensitive, since it is entirely under the control of the host system. In practice though, no widely used mail systems distinguish different addresses based on case. The part after the @ sign however is the domain and according to RFC 1035, section 3.1, "Name servers and resolvers must compare [domains] in a case-insensitive manner" In short, you are safe to treat email addresses as case-insensitive. I know this

Example: flutter check internet connection import 'package:connectivity/connectivity.dart' ; var connectivityResult = await ( Connectivity ( ) . checkConnectivity ( ) ) ; if ( connectivityResult == ConnectivityResult . mobile ) { // I am connected to a mobile network. } else if ( connectivityResult == ConnectivityResult . wifi ) { // I am connected to a wifi network. } //connectivity: any

Answer : The input to the des command shouldn't be in base64. Instead, you need to first decode the base64 output and then provide it to the OpenSSL des command. For instance, when I run the following on Linux: echo U2FsdGVkX18ztmw81FTK/c+jAf8xtcZdIpesuV2PLDM= | openssl enc -base64 -d | openssl des -d I get the correct output: hello world Since Windows is not great with pipes, you have to redirect the output to intermediate files and then run individual openssl commands. Openssl can base64 decode and decrypt in the same step with the -a or -base64 switch. But there is a bug in openssl's base64 processing, it expects a newline at the end of the base64 encoded data. The easiest solution is to base64 --decode before decrypting. For example, consider this base64 encrypted output: # echo foo | openssl enc -aes256 -md sha512 -pass pass:pass -e -base64 U2FsdGVkX182tdJx07S5YoPzi9XhyONdR8Xbc6V1jiw= If this is sent with a newline, it works fine. But if not, it

Answer : Answer: 1. You MUST load the HTML into string: private String readHtml(String remoteUrl) { String out = ""; BufferedReader in = null; try { URL url = new URL(remoteUrl); in = new BufferedReader(new InputStreamReader(url.openStream())); String str; while ((str = in.readLine()) != null) { out += str; } } catch (MalformedURLException e) { } catch (IOException e) { } finally { if (in != null) { try { in.close(); } catch (IOException e) { e.printStackTrace(); } } } return out; } 2. Load WebView with base URL: String html = readHtml("http://mydomain.com/my.html"); mWebView.loadDataWithBaseURL("file:///android_asset/", html, "text/html", "utf-8", ""); In this particular case you should have all .js files you want to use on the page to reside som

Answer : If you don't want longtable to add headers and footers to the table at the same time that multicol is balancing where to make the break (which would require that frank and I cooperate:-) then multicol will balance the output from longtable if you first trick longtable into thinking that it isn't in multicol at all. I added some rules, just to show that latex tabular features then work, which is harder to do with a bare \halign . \documentclass[11pt, a4paper]{article} \usepackage[margin=3cm]{geometry} \usepackage{longtable} \usepackage{multicol} \newsavebox\ltmcbox \def\shortlipsum{\par Lorem ipsum dolor sit amet, consectetuer adipiscing elit.
