Originally, I mentioned in 2012 git archive (see Jared Forsyth's answer and Robert Knight's answer), since git1.7.9.5 (March 2012), Paul Brannan's answer:

git archive --format=tar --remote=origin HEAD:path/to/directory -- filename | tar -O -xf -

But: in 2013, that was no longer possible for remote https://github.com URLs.
See the old page "Can I archive a repository?"

The current (2018) page "About archiving content and data on GitHub" recommends using third-party services like GHTorrent or GH Archive.

So you can also deal with local copies/clone:

You could alternatively do the following if you have a local copy of the bare repository as mentioned in this answer,

git --no-pager --git-dir /path/to/bar/repo.git show branch:path/to/file >file

Or you must clone first the repo, meaning you get the full history: - in the .git repo - in the working tree.

• But then you can do a sparse checkout (if you are using Git1.7+),:
  • enable the sparse checkout option (git config core.sparsecheckout true)
  • adding what you want to see in the .git/info/sparse-checkout file
  • re-reading the working tree to only display what you need

To re-read the working tree:

$ git read-tree -m -u HEAD

That way, you end up with a working tree including precisely what you want (even if it is only one file)

Richard Gomes points (in the comments) to "How do I clone, fetch or sparse checkout a single directory or a list of directories from git repository?"

A bash function which avoids downloading the history, which retrieves a single branch and which retrieves a list of files or directories you need.

If you already have the full local copy, you can remove unwanted sub folders by using --set-depth command.

svn update --set-depth=exclude www

See: http://blogs.collab.net/subversion/sparse-directories-now-with-exclusion

The set-depth command support multipile paths.

Updating the root local copy will not change the depth of the modified folder.

To restore the folder to being recusively checkingout, you could use --set-depth again with infinity param.

svn update --set-depth=infinity www

For the case of simply discarding changes, the git checkout -- path/ or git checkout HEAD -- path/ commands suggested by other answers work great. However, when you wish to reset a directory to a revision other than HEAD, that solution has a significant problem: it doesn't remove files which were deleted in the target revision.

So instead, I have begun using the following command:

git diff --cached commit -- subdir | git apply -R --index

This works by finding the diff between the target commit and the index, then applying that diff in reverse to the working directory and index. Basically, this means that it makes the contents of the index match the contents of the revision you specified. The fact that git diff takes a path argument allows you to limit this effect to a specific file or directory.

Since this command fairly long and I plan on using it frequently, I have set up an alias for it which I named reset-checkout:

git config --global alias.reset-checkout '!f() { git diff --cached "$@" | git apply -R --index; }; f'

You can use it like this:

git reset-checkout 451a9a4 -- path/to/directory

Or just:

git reset-checkout 451a9a4

For other users who just want to download a file/folder from github, simply use:

svn export <repo>/trunk/<folder>

e.g.

svn export https://github.com/lodash/lodash.com/trunk/docs

(yes, that's svn here. apparently in 2016 you still need svn to simply download some github files)

Courtesy: Download a single folder or directory from a GitHub repo

Important - Make sure you update the github URL and replace /tree/master/ with '/trunk/'.

As bash script:

git-download(){
    folder=${@/tree\/master/trunk}
    folder=${folder/blob\/master/trunk}
    svn export $folder
}

Note This method downloads a folder, does not clone/checkout it. You can't push changes back to the repository. On the other hand - this results in smaller download compared to sparse checkout or shallow checkout.

Sparse checkouts are now in Git 1.7.

Also see the question “Is it possible to do a sparse checkout without checking out the whole repository first?”.

Note that sparse checkouts still require you to download the whole repository, even though some of the files Git downloads won't end up in your working tree.

The following 2 commands worked for me:

git archive --remote={remote_repo_git_url} {branch} {file_to_download} -o {tar_out_file}

Downloads file_to_download as tar archive from branch of remote repository whose url is remote_repo_git_url and stores it in tar_out_file

tar -x -f {tar_out_file}.tar extracts the file_to_download from tar_out_file

The problem occurred because of wrong table type.MyISAM is the only type of table that Mysql supports for Full-text indexes.

To correct this error run following sql.

 CREATE TABLE gamemech_chat (
  id bigint(20) unsigned NOT NULL auto_increment,
  from_userid varchar(50) NOT NULL default '0',
  to_userid varchar(50) NOT NULL default '0',
  text text NOT NULL,
  systemtext text NOT NULL,
  timestamp datetime NOT NULL default '0000-00-00 00:00:00',
  chatroom bigint(20) NOT NULL default '0',
  PRIMARY KEY  (id),
  KEY from_userid (from_userid),
  FULLTEXT KEY from_userid_2 (from_userid),
  KEY chatroom (chatroom),
  KEY timestamp (timestamp)
) ENGINE=MyISAM;

Specify bash instead of sh when running the script. I personally noticed they are different under ubuntu 12.10:

bash script.sh arg0 ... argn

$data = $this->db->get_where('columnname',array('code' => 'B'));
$this->db->where_in('columnname',$data);
$this->db->where('code !=','B');
$query =  $this->db->get();
return $query->result_array();

For log4j 2 API , you can use

Logger logger = LogManager.getRootLogger();
Configurator.setAllLevels(logger.getName(), Level.getLevel(level));

Here is the example:

SQL> set define off;
SQL> select * from dual where dummy='&var';

no rows selected

SQL> set define on
SQL> /
Enter value for var: X
old   1: select * from dual where dummy='&var'
new   1: select * from dual where dummy='X'

D
-
X

With set define off, it took a row with &var value, prompted a user to enter a value for it and replaced &var with the entered value (in this case, X).

You could attach to the KeyDown event and then query the database for that portion of the text that the user has already entered. For example, if the user enters "T", search for things that start with "T". Then, when they enter the next letter, for example "e", search for things in the table that start with "Te".

The available items could be displayed in a "floating" ListBox, for example. You would need to place the ListBox just beneath the TextBox so that they can see the entries available, then remove the ListBox when they're done typing.

A simple definition: A web service is a function that can be accessed by other programs over the web (HTTP).

For example, when you create a website in PHP that outputs HTML, its target is the browser and by extension the human reading the page in the browser. A web service is not targeted at humans but rather at other programs.

So your PHP site that generates a random integer could be a web service if it outputs the integer in a format that may be consumed by another program. It might be in an XML format or another format, as long as other programs can understand the output.

The full definition is obviously more complex but you asked for plain English.

git remote add origin <remote_repo_url>
git push --all origin

If you want to set all of your branches to automatically use this remote repo when you use git pull, add --set-upstream to the push:

git push --all --set-upstream origin

The listings package is quite nice and very flexible (e.g. different sizes for comments and code).

Try using printf function or the concatination operator

http://php.net/manual/en/function.printf.php

On line 2 change new FileWriter(my_file_name) to new FileWriter(my_file_name, true) so you're appending to the file rather than overwriting.

File f = new File("/path/of/the/file");
        try {
            BufferedWriter bw = new BufferedWriter(new FileWriter(f, true));
            bw.append(line);
            bw.close();
        } catch (IOException e) {
            System.out.println(e.getMessage());

To add to @Christian's comment:

Replace all single or double quotes in a string:

s = "'asdfa sdfa'"

import re
re.sub("[\"\']", "", s)

The #1 reason has already been stated - it hides errors that you did not expect.

(#2) - It makes your code difficult for others to read and understand. If you catch a FileNotFoundException when you are trying to read a file, then it is pretty obvious to another developer what functionality the 'catch' block should have. If you do not specify an exception, then you need additional commenting to explain what the block should do.

(#3) - It demonstrates lazy programming. If you use the generic try/catch, it indicates either that you do not understand the possible run-time errors in your program, or that you do not know what exceptions are possible in Python. Catching a specific error shows that you understand both your program and the range of errors that Python throws. This is more likely to make other developers and code-reviewers trust your work.

The obj folder holds object, or intermediate, files, which are compiled binary files that haven't been linked yet. They're essentially fragments that will be combined to produce the final executable. The compiler generates one object file for each source file, and those files are placed into the obj folder.

The bin folder holds binary files, which are the actual executable code for your application or library.

Each of these folders are further subdivided into Debug and Release folders, which simply correspond to the project's build configurations. The two types of files discussed above are placed into the appropriate folder, depending on which type of build you perform. This makes it easy for you to determine which executables are built with debugging symbols, and which were built with optimizations enabled and ready for release.

Note that you can change where Visual Studio outputs your executable files during a compile in your project's Properties. You can also change the names and selected options for your build configurations.

Solution when dropping a list of column names containing regex. I prefer this approach because I'm frequently editing the drop list. Uses a negative filter regex for the drop list.

drop_column_names = ['A','B.+','C.*']
drop_columns_regex = '^(?!(?:'+'|'.join(drop_column_names)+')$)'
print('Dropping columns:',', '.join([c for c in df.columns if re.search(drop_columns_regex,c)]))
df = df.filter(regex=drop_columns_regex,axis=1)

Stopwatch is designed for this purpose and is one of the best ways to measure time execution in .NET.

var watch = System.Diagnostics.Stopwatch.StartNew();
// the code that you want to measure comes here
watch.Stop();
var elapsedMs = watch.ElapsedMilliseconds;

Do not use DateTime to measure time execution in .NET.

UPDATE:

As pointed out by @series0ne in the comments section: If you want a real precise measurement of the execution of some code, you will have to use the performance counters that's built into the operating system. The following answer contains a nice overview.

Here's a list of things that are worth checking:

Is Suhosin installed?

• How to check whether Suhosin is installed?

ini_set

• The format is important ini_set('memory_limit', '512'); // DIDN'T WORK ini_set('memory_limit', '512MB'); // DIDN'T WORK ini_set('memory_limit', '512M'); // OK - 512MB ini_set('memory_limit', 512000000); // OK - 512MB

When an integer is used, the value is measured in bytes. Shorthand notation, as described in this FAQ, may also be used.

http://php.net/manual/en/ini.core.php#ini.memory-limit

• Has php_admin_value been used in .htaccess or virtualhost files?

Sets the value of the specified directive. This can not be used in .htaccess files. Any directive type set with php_admin_value can not be overridden by .htaccess or ini_set(). To clear a previously set value use none as the value.

The only easy way to do this is to use snprintf to print to a buffer that's long enough to hold the entire, exact value, then truncate it as a string. Something like:

char buf[2*(DBL_MANT_DIG + DBL_MAX_EXP)];
snprintf(buf, sizeof buf, "%.*f", (int)sizeof buf, x);
char *p = strchr(buf, '.'); // beware locale-specific radix char, though!
p[2+1] = 0;
puts(buf);

Looks like you're accidentally calling the handleButtonChange method in your render method, you probably want to do onClick={() => this.handleButtonChange(false)} instead.

If you don't want to create a lambda in the onClick handler, I think you'll need to have two bound methods, one for each parameter.

In the constructor:

this.handleButtonChangeRetour = this.handleButtonChange.bind(this, true);
this.handleButtonChangeSingle = this.handleButtonChange.bind(this, false);

And in the render method:

<Button href="#" active={!this.state.singleJourney} onClick={this.handleButtonChangeSingle} >Retour</Button>
<Button href="#" active={this.state.singleJourney} onClick={this.handleButtonChangeRetour}>Single Journey</Button>

I'm betting the problem is that Cygwin is writing Unix line endings (LF) to the file, and you're opening it with a program that expects Windows line-endings (CRLF). To determine if this is the case — and for a bit of a hackish workaround — try:

echo "`date` User `whoami` started the script."$'\r' >> output.log

(where the $'\r' at the end is an extra carriage-return; it, plus the Unix line ending, will result in a Windows line ending).

This should work, I tried it by myself and it worked for me. If you pass True instead of false, the print dialog will appear.

this.print(false);

Your @POST method should be accepting a JSON object instead of a string. Jersey uses JAXB to support marshaling and unmarshaling JSON objects (see the jersey docs for details). Create a class like:

@XmlRootElement
public class MyJaxBean {
    @XmlElement public String param1;
    @XmlElement public String param2;
}

Then your @POST method would look like the following:

@POST @Consumes("application/json")
@Path("/create")
public void create(final MyJaxBean input) {
    System.out.println("param1 = " + input.param1);
    System.out.println("param2 = " + input.param2);
}

This method expects to receive JSON object as the body of the HTTP POST. JAX-RS passes the content body of the HTTP message as an unannotated parameter -- input in this case. The actual message would look something like:

POST /create HTTP/1.1
Content-Type: application/json
Content-Length: 35
Host: www.example.com

{"param1":"hello","param2":"world"}

Using JSON in this way is quite common for obvious reasons. However, if you are generating or consuming it in something other than JavaScript, then you do have to be careful to properly escape the data. In JAX-RS, you would use a MessageBodyReader and MessageBodyWriter to implement this. I believe that Jersey already has implementations for the required types (e.g., Java primitives and JAXB wrapped classes) as well as for JSON. JAX-RS supports a number of other methods for passing data. These don't require the creation of a new class since the data is passed using simple argument passing.

HTML <FORM>

The parameters would be annotated using @FormParam:

@POST
@Path("/create")
public void create(@FormParam("param1") String param1,
                   @FormParam("param2") String param2) {
    ...
}

The browser will encode the form using "application/x-www-form-urlencoded". The JAX-RS runtime will take care of decoding the body and passing it to the method. Here's what you should see on the wire:

POST /create HTTP/1.1
Host: www.example.com
Content-Type: application/x-www-form-urlencoded;charset=UTF-8
Content-Length: 25

param1=hello&param2=world

The content is URL encoded in this case.

If you do not know the names of the FormParam's you can do the following:

@POST @Consumes("application/x-www-form-urlencoded")
@Path("/create")
public void create(final MultivaluedMap<String, String> formParams) {
    ...
}

HTTP Headers

You can using the @HeaderParam annotation if you want to pass parameters via HTTP headers:

@POST
@Path("/create")
public void create(@HeaderParam("param1") String param1,
                   @HeaderParam("param2") String param2) {
    ...
}

Here's what the HTTP message would look like. Note that this POST does not have a body.

POST /create HTTP/1.1
Content-Length: 0
Host: www.example.com
param1: hello
param2: world

I wouldn't use this method for generalized parameter passing. It is really handy if you need to access the value of a particular HTTP header though.

HTTP Query Parameters

This method is primarily used with HTTP GETs but it is equally applicable to POSTs. It uses the @QueryParam annotation.

@POST
@Path("/create")
public void create(@QueryParam("param1") String param1,
                   @QueryParam("param2") String param2) {
    ...
}

Like the previous technique, passing parameters via the query string does not require a message body. Here's the HTTP message:

POST /create?param1=hello&param2=world HTTP/1.1
Content-Length: 0
Host: www.example.com

You do have to be particularly careful to properly encode query parameters on the client side. Using query parameters can be problematic due to URL length restrictions enforced by some proxies as well as problems associated with encoding them.

HTTP Path Parameters

Path parameters are similar to query parameters except that they are embedded in the HTTP resource path. This method seems to be in favor today. There are impacts with respect to HTTP caching since the path is what really defines the HTTP resource. The code looks a little different than the others since the @Path annotation is modified and it uses @PathParam:

@POST
@Path("/create/{param1}/{param2}")
public void create(@PathParam("param1") String param1,
                   @PathParam("param2") String param2) {
    ...
}

The message is similar to the query parameter version except that the names of the parameters are not included anywhere in the message.

POST /create/hello/world HTTP/1.1
Content-Length: 0
Host: www.example.com

This method shares the same encoding woes that the query parameter version. Path segments are encoded differently so you do have to be careful there as well.

As you can see, there are pros and cons to each method. The choice is usually decided by your clients. If you are serving FORM-based HTML pages, then use @FormParam. If your clients are JavaScript+HTML5-based, then you will probably want to use JAXB-based serialization and JSON objects. The MessageBodyReader/Writer implementations should take care of the necessary escaping for you so that is one fewer thing that can go wrong. If your client is Java based but does not have a good XML processor (e.g., Android), then I would probably use FORM encoding since a content body is easier to generate and encode properly than URLs are. Hopefully this mini-wiki entry sheds some light on the various methods that JAX-RS supports.

Note: in the interest of full disclosure, I haven't actually used this feature of Jersey yet. We were tinkering with it since we have a number of JAXB+JAX-RS applications deployed and are moving into the mobile client space. JSON is a much better fit that XML on HTML5 or jQuery-based solutions.

The SignTool is available as part of the Windows SDK (which comes with Visual Studio Community 2015). Make sure to select the "ClickOnce Publishing Tools" from the feature list during the installation of Visual Studio 2015 to get the SignTool.

Once Visual Studio is installed you can run the signtool command from the Visual Studio Command Prompt. By default (on Windows 10) the SignTool will be installed at C:\Program Files (x86)\Windows Kits\10\bin\x86\signtool.exe.

I had been avoiding this by calling a method to run [cell.contentView bringSubviewToFront:textField] every time my cells appeared, but then I discovered this relatively simple technique:

cell.accessoryView = textField;

Doesn't seem to have the same background-overpasting issue, and it aligns itself on its own (somewhat). Also, the textLabel auto-truncates to avoid overflowing into (or under) it, which is handy.

This isn't in the boto3 documentation. This worked for me:

object.get()["Body"].read()

object being an s3 object: http://boto3.readthedocs.org/en/latest/reference/services/s3.html#object

This does exist, but it's actually a feature of git log:

git log -p [--follow] [-1] <path>

Note that -p can also be used to show the inline diff from a single commit:

git log -p -1 <commit>

Options used:

• -p (also -u or --patch) is hidden deeeeeeeep in the git-log man page, and is actually a display option for git-diff. When used with log, it shows the patch that would be generated for each commit, along with the commit information—and hides commits that do not touch the specified <path>. (This behavior is described in the paragraph on --full-diff, which causes the full diff of each commit to be shown.)
• -1 shows just the most recent change to the specified file (-n 1 can be used instead of -1); otherwise, all non-zero diffs of that file are shown.
• --follow is required to see changes that occurred prior to a rename.

As far as I can tell, this is the only way to immediately see the last set of changes made to a file without using git log (or similar) to either count the number of intervening revisions or determine the hash of the commit.

To see older revisions changes, just scroll through the log, or specify a commit or tag from which to start the log. (Of course, specifying a commit or tag returns you to the original problem of figuring out what the correct commit or tag is.)

Credit where credit is due:

• I discovered log -p thanks to this answer.
• Credit to FranciscoPuga and this answer for showing me the --follow option.
• Credit to ChrisBetti for mentioning the -n 1 option and atatko for mentioning the -1 variant.
• Credit to sweaver2112 for getting me to actually read the documentation and figure out what -p "means" semantically.

just add /FORCE as linker flag and you're all set.

for instance, if you're working on CMakeLists.txt. Then add following line:

SET(CMAKE_EXE_LINKER_FLAGS  "/FORCE")

Add grid with defined height and width for columns and rows. Then add ScrollViewer and inside it add the dataGrid.

As an aside, apart from the answer by mipadi (which should work by the way), you should know that doing:

git branch -D master
git checkout master

also does exactly what you want without having to redownload everything (your quote paraphrased). That is because your local repo contains a copy of the remote repo (and that copy is not the same as your local directory, it is not even the same as your checked out branch).

Wiping out a branch is perfectly safe and reconstructing that branch is very fast and involves no network traffic. Remember, git is primarily a local repo by design. Even remote branches have a copy on the local. There's only a bit of metadata that tells git that a specific local copy is actually a remote branch. In git, all files are on your hard disk all the time.

If you don't have any branches other than master, you should:

git checkout -b 'temp'
git branch -D master

Suppose you want to give attributes to an instance which was previously not written in code. The setattr() does just that. It takes the instance of the class self and key and value to set.

class Example:
    def __init__(self, **kwargs):
        for key, value in kwargs.items():
            setattr(self, key, value)

I improved code i used

public static float getAPIVerison() {

    float f=1f;
    try {
        StringBuilder strBuild = new StringBuilder();
        strBuild.append(android.os.Build.VERSION.RELEASE.substring(0, 2));
        f= Float.valueOf(strBuild.toString());
    } catch (NumberFormatException e) {
        Log.e("myApp", "error retriving api version" + e.getMessage());
    }

    return f;
}

Standard is use is or has as a prefix. For example isValid, hasChildren.

Surprised to see no one mentioned more capable, interactive and easier to use alternatives.

A) You can use plotly:

1. Just two lines and you get:

2. interactivity,

3. smooth scale,

4. colors based on whole dataframe instead of individual columns,

5. column names & row indices on axes,

6. zooming in,

7. panning,

8. built-in one-click ability to save it as a PNG format,

9. auto-scaling,

10. comparison on hovering,

11. bubbles showing values so heatmap still looks good and you can see values wherever you want:

import plotly.express as px
fig = px.imshow(df.corr())
fig.show()

B) You can also use Bokeh:

All the same functionality with a tad much hassle. But still worth it if you do not want to opt-in for plotly and still want all these things:

from bokeh.plotting import figure, show, output_notebook
from bokeh.models import ColumnDataSource, LinearColorMapper
from bokeh.transform import transform
output_notebook()
colors = ['#d7191c', '#fdae61', '#ffffbf', '#a6d96a', '#1a9641']
TOOLS = "hover,save,pan,box_zoom,reset,wheel_zoom"
data = df.corr().stack().rename("value").reset_index()
p = figure(x_range=list(df.columns), y_range=list(df.index), tools=TOOLS, toolbar_location='below',
           tooltips=[('Row, Column', '@level_0 x @level_1'), ('value', '@value')], height = 500, width = 500)

p.rect(x="level_1", y="level_0", width=1, height=1,
       source=data,
       fill_color={'field': 'value', 'transform': LinearColorMapper(palette=colors, low=data.value.min(), high=data.value.max())},
       line_color=None)
color_bar = ColorBar(color_mapper=LinearColorMapper(palette=colors, low=data.value.min(), high=data.value.max()), major_label_text_font_size="7px",
                     ticker=BasicTicker(desired_num_ticks=len(colors)),
                     formatter=PrintfTickFormatter(format="%f"),
                     label_standoff=6, border_line_color=None, location=(0, 0))
p.add_layout(color_bar, 'right')

show(p)

Use a good XSD Schema to create a set of classes with xsd.exe and use an XmlSerializer to create a object tree out of your XML and vice versa. If you have few restrictions on your model, you could even try to create a direct mapping between you model classes and the XML with the Xml*Attributes.

There is an introductory article about XML Serialisation on MSDN.

Performance tip: Constructing an XmlSerializer is expensive. Keep a reference to your XmlSerializer instance if you intend to parse/write multiple XML files.

It would be more beneficial for us if we could see the actual project structure, as the classes alone do not say that much.

Assuming that both .cs files are in the same project (if they are in different projects inside the same solution, you'd have to add a reference to the project containing Class2.cs), you can click on the Class2 occurrence in your code that is underlined in red and press CTRL + . (period) or click on the blue bar that should be there. The first option appearing will then add the appropriate using statement automatically. If there is no such menu, it may indicate that there is something wrong with the project structure or a reference missing.

You could try making Class2 public, but it sounds like this can't be a problem here, since by default what you did is internal class Class2 and thus Class2 should be accessible if both are living in the same project/assembly. If you are referencing a different assembly or project wherein Class2 is contained, you have to make it public in order to access it, as internal classes can't be accessed from outside their assembly.

As for renaming: You can click Program.cs in the Solution Explorer and press F2 to rename it. It will then open up a dialog window asking you if the class Program itself and all references thereof should be renamed as well, which is usually what you want. Or you could just rename the class Program in the declaration and again open up the menu with the small blue bar (or, again, CTRL+.) and do the same, but it won't automatically rename the actual file accordingly.

Edit after your question edit: I have never used this option you used, but from quick checking I think that it's really not inside the same project then. Do the following when adding new classes to a project: In the Solution Explorer, right click the project you created and select [Add] -> [Class] or [Add] -> [New Item...] and then select 'Class'. This will automatically make the new class part of the project and thus the assembly (the assembly is basically the 'end product' after building the project). For me, there is also the shortcut Alt+Shift+C working to create a new class.

If you are using Spyder, the lines just print continuously with all the previous solutions. A way to avoid that is using:

for i in range(1000):
    print('\r' + str(round(i/len(df)*100,1)) + '% complete', end='')
    sys.stdout.flush()

it has been a while but my answer may help someone:

if you already defined the relation properly you can use this:

        var res = query.Products.Select(m => new
        {
            productID = product.Id,
            categoryID = m.ProductCategory.Select(s => s.Category.ID).ToList(),
        }).ToList();

URLs are not resolved based on the file structure in the server side. URLs are resolved based on the real public web addresses of the resources in question. It's namely the webbrowser who has got to invoke them, not the webserver.

There are several ways to soften the pain:

JSF EL offers a shorthand to ${pageContext.request} in flavor of #{request}:

<li><a href="#{request.contextPath}/index.xhtml">Home</a></li>
<li><a href="#{request.contextPath}/about_us.xhtml">About us</a></li>

You can if necessary use <c:set> tag to make it yet shorter. Put it somewhere in the master template, it'll be available to all pages:

<c:set var="root" value="#{request.contextPath}/" />
...
<li><a href="#{root}index.xhtml">Home</a></li>
<li><a href="#{root}about_us.xhtml">About us</a></li>

JSF 2.x offers the <h:link> which can take a view ID relative to the context root in outcome and it will append the context path and FacesServlet mapping automatically:

<li><h:link value="Home" outcome="index" /></li>
<li><h:link value="About us" outcome="about_us" /></li>

HTML offers the <base> tag which makes all relative URLs in the document relative to this base. You could make use of it. Put it in the <h:head>.

<base href="#{request.requestURL.substring(0, request.requestURL.length() - request.requestURI.length())}#{request.contextPath}/" />
...
<li><a href="index.xhtml">Home</a></li>
<li><a href="about_us.xhtml">About us</a></li>

(note: this requires EL 2.2, otherwise you'd better use JSTL fn:substring(), see also this answer)

This should end up in the generated HTML something like as

<base href="http://example.com/webname/" />

Note that the <base> tag has a caveat: it makes all jump anchors in the page like <a href="#top"> relative to it as well! See also Is it recommended to use the <base> html tag? In JSF you could solve it like <a href="#{request.requestURI}#top">top</a> or <h:link value="top" fragment="top" />.

Steps that you should follow if you want the thread dump of your StandAlone Java Process

Step 1: Get the Process ID for the shell script calling the java program

linux$ ps -aef | grep "runABCD"

user1  **8535**  4369   0   Mar 25 ?           0:00 /bin/csh /home/user1/runABCD.sh

user1 17796 17372   0 08:15:41 pts/49      0:00 grep runABCD

Step 2: Get the Process ID for the Child which was Invoked by the runABCD. Use the above PID to get the childs.

linux$ ps -aef | grep **8535**

user1  **8536**  8535   0   Mar 25 ?         126:38 /apps/java/jdk/sun4/SunOS5/1.6.0_16/bin/java -cp /home/user1/XYZServer

user1  8535  4369   0   Mar 25 ?           0:00 /bin/csh /home/user1/runABCD.sh

user1 17977 17372   0 08:15:49 pts/49      0:00 grep 8535

Step 3: Get the JSTACK for the particular process. Get the Process id of your XYSServer process. i.e. 8536

linux$ jstack **8536** > threadDump.log

You can check the Ascii value by e.keychar on KeyPress event of TextBox.

By checking the AscII value you can check for number or character.

Similarly you can write logic to check the Email ID.

pip3 install mysql-connector-python did solve my problem as well. Ignore using mysql-connector module.

<html>
<head>
<script type="text/javascript">
function striptag(){
var html = /(<([^>]+)>)/gi;
for (i=0; i < arguments.length; i++)
arguments[i].value=arguments[i].value.replace(html, "")
}
</script>
</head> 
<body>
       <form name="myform">
<textarea class="comment" title="comment" name=comment rows=4 cols=40></textarea><br>
<input type="button" value="Remove HTML Tags" onClick="striptag(this.form.comment)">

It seems that you can transfer your Certificates and Provisioning profiles from one machine to the other, so if you are having issues in setting up your certificate and/or profiles because you migrated your Dev machine, have a look at this:

how to transfer xcode certificates between macs

No-one has mentioned cpio which is easy to type, creates hard links and handles spaces in filenames:

git diff --name-only $from..$to  | cpio -pld outdir

Perhaps a more pythonic way of doing so.

from numpy import *
import math
import matplotlib.pyplot as plt

t = linspace(0,2*math.pi,400)
a = sin(t)
b = cos(t)
c = a + b

plt.plot(t, a, t, b, t, c)
plt.show()

You can do it with:

NSNumber *myNumber = @15;
NSString *myNumberInString = [myNumber stringValue];

You can try:

std::map <int, int> mymap = 
{
        std::pair <int, int> (1, 1),
        std::pair <int, int> (2, 2),
        std::pair <int, int> (2, 2)
};

Update - I verified the below works. Maybe the creation of your JArray isn't quite right.

            var myElementValue = myElement.Value; ////This is a JValue type

So call Children on your JArray to get each JObject in JArray. Call Children on each JObject to access the objects properties.

foreach(var item in yourJArray.Children())
{
    var itemProperties = item.Children<JProperty>();
    //you could do a foreach or a linq here depending on what you need to do exactly with the value
    var myElement = itemProperties.FirstOrDefault(x => x.Name == "url");
    var myElementValue = myElement.Value; ////This is a JValue type
}

Answer 1:

To convert a string to a sequence of bytes in either Python 2 or Python 3, you use the string's encode method. If you don't supply an encoding parameter 'ascii' is used, which will always be good enough for numeric digits.

s = str(n).encode()

• Python 2: http://ideone.com/Y05zVY
• Python 3: http://ideone.com/XqFyOj

In Python 2 str(n) already produces bytes; the encode will do a double conversion as this string is implicitly converted to Unicode and back again to bytes. It's unnecessary work, but it's harmless and is completely compatible with Python 3.

Above is the answer to the question that was actually asked, which was to produce a string of ASCII bytes in human-readable form. But since people keep coming here trying to get the answer to a different question, I'll answer that question too. If you want to convert 10 to b'10' use the answer above, but if you want to convert 10 to b'\x0a\x00\x00\x00' then keep reading.

The struct module was specifically provided for converting between various types and their binary representation as a sequence of bytes. The conversion from a type to bytes is done with struct.pack. There's a format parameter fmt that determines which conversion it should perform. For a 4-byte integer, that would be i for signed numbers or I for unsigned numbers. For more possibilities see the format character table, and see the byte order, size, and alignment table for options when the output is more than a single byte.

import struct
s = struct.pack('<i', 5) # b'\x05\x00\x00\x00'

If you have a valid $GOROOT and $GOPATH but are developing outside of them, you might get this error if the package (yours or someone else's) hasn't been downloaded.

If that's the case, try go get -d (-d flag prevents installation) to ensure the package is downloaded before you run, build or install.

If you want to test for a specific error type, use a combination of try, catch and raise:

#-- test for TypeError
try:
  myList.append_number("a")
  assert False
except TypeError: pass
except: assert False

instead of the cookie variable you would just use document.cookie.split...

var cookie = 'cookie1=s; cookie1=; cookie2=test';_x000D_
var cookies = cookie.split('; ');_x000D_
cookies.forEach(function(c){_x000D_
  if(c.match(/cookie1=.+/))_x000D_
   console.log(true);_x000D_
});

In addition to @JBNizet's answer, my general use case for ifPresent is to combine .isPresent() and .get():

Old way:

Optional opt = getIntOptional();
if(opt.isPresent()) {
    Integer value = opt.get();
    // do something with value
}

New way:

Optional opt = getIntOptional();
opt.ifPresent(value -> {
    // do something with value
})

This, to me, is more intuitive.

You just need to add @JoinColumn(name="column_name") to Host Entity relation . column_name is the database column name in person table.

@Entity
public class Person {
    @Id
    public int id;

    @OneToOne
    @JoinColumn(name="other_info")
    public OtherInfo otherInfo;

    rest of attributes ...
}

Person has a one-to-one relationship with OtherInfo: mappedBy="var_name" var_name is variable name for otherInfo in Person class.

@Entity
public class OtherInfo {
    @Id
    @OneToOne(mappedBy="otherInfo")
    public Person person;

    rest of attributes ...
}

For anybody interested in Titanium i must say that they don't have a very good documentation some classes, properties, methods are missing. But a lot is "documented" in their sample app the KitchenSink so it is not THAT bad.

Assuming you must have two tables for the two employee types for some reason, I'll extend on vmarquez's answer:

Schema:

employees_ce (id, name)
employees_sn (id, name)
deductions (id, parentId, parentType, name)

Data in deductions:

deductions table
id      parentId      parentType      name
1       1             ce              gold
2       1             sn              silver
3       2             sn              wood
...

This would allow you to have deductions point to any other table in your schema. This kind of relation isn't supported by database-level constraints, IIRC so you'll have to make sure your App manages the constraint properly (which makes it more cumbersome if you have several different Apps/services hitting the same database).

A much easier solution IMHO ...................

What changes in c++20

Following the rest of the clear theme of this question, the meaning and use of aggregates continues to change with every standard. There are several key changes on the horizon.

Types with user-declared constructors P1008

In C++17, this type is still an aggregate:

struct X {
    X() = delete;
};

And hence, X{} still compiles because that is aggregate initialization - not a constructor invocation. See also: When is a private constructor not a private constructor?

In C++20, the restriction will change from requiring:

no user-provided, explicit, or inherited constructors

to

no user-declared or inherited constructors

This has been adopted into the C++20 working draft. Neither the X here nor the C in the linked question will be aggregates in C++20.

This also makes for a yo-yo effect with the following example:

class A { protected: A() { }; };
struct B : A { B() = default; };
auto x = B{};

In C++11/14, B was not an aggregate due to the base class, so B{} performs value-initialization which calls B::B() which calls A::A(), at a point where it is accessible. This was well-formed.

In C++17, B became an aggregate because base classes were allowed, which made B{} aggregate-initialization. This requires copy-list-initializing an A from {}, but from outside the context of B, where it is not accessible. In C++17, this is ill-formed (auto x = B(); would be fine though).

In C++20 now, because of the above rule change, B once again ceases to be an aggregate (not because of the base class, but because of the user-declared default constructor - even though it's defaulted). So we're back to going through B's constructor, and this snippet becomes well-formed.

Initializing aggregates from a parenthesized list of values P960

A common issue that comes up is wanting to use emplace()-style constructors with aggregates:

struct X { int a, b; };
std::vector<X> xs;
xs.emplace_back(1, 2); // error

This does not work, because emplace will try to effectively perform the initialization X(1, 2), which is not valid. The typical solution is to add a constructor to X, but with this proposal (currently working its way through Core), aggregates will effectively have synthesized constructors which do the right thing - and behave like regular constructors. The above code will compile as-is in C++20.

Class Template Argument Deduction (CTAD) for Aggregates P1021 (specifically P1816)

In C++17, this does not compile:

template <typename T>
struct Point {
    T x, y;
};

Point p{1, 2}; // error

Users would have to write their own deduction guide for all aggregate templates:

template <typename T> Point(T, T) -> Point<T>;

But as this is in some sense "the obvious thing" to do, and is basically just boilerplate, the language will do this for you. This example will compile in C++20 (without the need for the user-provided deduction guide).

This should work:

@interface MyClass
{
    int _doubleDigits[10]; 
}

@property(readonly) int *doubleDigits;

@end

@implementation MyClass

- (int *)doubleDigits
{
    return _doubleDigits;
}

@end

$(".list li").sort(asc_sort).appendTo('.list');
//$("#debug").text("Output:");
// accending sort
function asc_sort(a, b){
    return ($(b).text()) < ($(a).text()) ? 1 : -1;    
}

// decending sort
function dec_sort(a, b){
    return ($(b).text()) > ($(a).text()) ? 1 : -1;    
}

An addition to Christopher Bradford's answer to use the HTML escaping anywhere, since most people don't use CGI nowadays, you can also use Rack:

require 'rack/utils'
Rack::Utils.escape_html('Usage: foo "bar" <baz>')

div hover background color change

Try like this:

.class_name:hover{
    background-color:#FF0000;
}

You can't do this with Html.ActionLink. You should use Url.RouteUrl and use the URL to construct the element you want.

prefix the comment with a single-quote. there is no need for an "end" tag.

'this is a comment

Extend to multiple lines using the line-continuation character, _:

'this is a multi-line _
   comment

This is an option in the toolbar to select a line(s) of code and comment/uncomment:

Yes, it can be done.
It is based on the new html5 "download" attribute of anchor tags.
The flow should be something like this :

1. load the image
2. draw the image into a canvas with the crop boundaries specified
3. get the image data from the canvas and make it a href attribute for an anchor tag in the dom
4. add the download attribute (download="desired-file-name") to that a element That's it. all the user has to do is click your "download link" and the image will be downloaded to his pc.

I'll come back with a demo when I get the chance.

Update
Here's the live demo as I promised. It takes the jsfiddle logo and crops 5px of each margin.
The code looks like this :

var img = new Image();
img.onload = function(){
    var cropMarginWidth = 5,
        canvas = $('<canvas/>')
                    .attr({
                         width: img.width - 2 * cropMarginWidth,
                         height: img.height - 2 * cropMarginWidth
                     })
                    .hide()
                    .appendTo('body'),
        ctx = canvas.get(0).getContext('2d'),
        a = $('<a download="cropped-image" title="click to download the image" />'),
        cropCoords = {
            topLeft : {
                x : cropMarginWidth,
                y : cropMarginWidth 
            },
            bottomRight :{
                x : img.width - cropMarginWidth,
                y : img.height - cropMarginWidth
            }
        };

    ctx.drawImage(img, cropCoords.topLeft.x, cropCoords.topLeft.y, cropCoords.bottomRight.x, cropCoords.bottomRight.y, 0, 0, img.width, img.height);
    var base64ImageData = canvas.get(0).toDataURL();


    a
        .attr('href', base64ImageData)
        .text('cropped image')
        .appendTo('body');

    a
        .clone()
        .attr('href', img.src)
        .text('original image')
        .attr('download','original-image')
        .appendTo('body');

    canvas.remove();
}
img.src = 'some-image-src';

Update II
Forgot to mention : of course there is a downside :(.
Because of the same-origin policy that is applied to images too, if you want to access an image's data (through the canvas method toDataUrl).
So you would still need a server-side proxy that would serve your image as if it were hosted on your domain.

Update III Although I can't provide a live demo for this (for security reasons), here is a php sample code that solves the same-origin policy :

file proxy.php :

$imgData = getimagesize($_GET['img']);
header("Content-type: " . $imgData['mime']);
echo file_get_contents($_GET['img']);  

This way, instead of loading the external image direct from it's origin :

img.src = 'http://some-domain.com/imagefile.png';

You can load it through your proxy :

img.src = 'proxy.php?img=' + encodeURIComponent('http://some-domain.com/imagefile.png');  

And here's a sample php code for saving the image data (base64) into an actual image :

file save-image.php :

$data = preg_replace('/data:image\/(png|jpg|jpeg|gif|bmp);base64/','',$_POST['data']);
$data = base64_decode($data);
$img = imagecreatefromstring($data);

$path = 'path-to-saved-images/';
// generate random name
$name  = substr(md5(time()),10);
$ext = 'png';
$imageName = $path.$name.'.'.$ext;

// write the image to disk
imagepng($img,  $imageName);
imagedestroy($img);
// return the image path
echo $imageName;

All you have to do then is post the image data to this file and it will save the image to disc and return you the existing image filename.

Of course all this might feel a bit complicated, but I wanted to show you that what you're trying to achieve is possible.

In node, you can just say

console.log(aa)

and it will format it as it should.

If you need to use the resulting string you should use

JSON.stringify(aa)

If you are the empirical type,

echo | gcc -E -xc -include 'stddef.h' - | grep size_t

Output for Ubuntu 14.04 64-bit GCC 4.8:

typedef long unsigned int size_t;

Note that stddef.h is provided by GCC and not glibc under src/gcc/ginclude/stddef.h in GCC 4.2.

Interesting C99 appearances

• malloc takes size_t as an argument, so it determines the maximum size that may be allocated.

  And since it is also returned by sizeof, I think it limits the maximum size of any array.

  See also: What is the maximum size of an array in C?

An easy way to do this is:

int main(int argc, char * argv[]){
    std::cout << argv[0]; 
    std::cin.get();
}

argv[] is pretty much an array containing arguments you ran the .exe with, but the first one is always a path to the executable. If I build this the console shows: C:\Users\Ulisse\source\repos\altcmd\Debug\currentdir.exe

To implement this the way you have started, you'll need to add an AnimationListener so that you can detect the beginning and ending of an animation. When onAnimationEnd() for the fade out is called, you can set the visibility of your ImageView object to View.INVISIBLE, switch the images and start your fade in animation - you'll need another AnimationListener here too. When you receive onAnimationEnd() for your fade in animation, set the ImageView to be View.VISIBLE and that should give you the effect you're looking for.

I've implemented a similar effect before, but I used a ViewSwitcher with 2 ImageViews rather than a single ImageView. You can set the "in" and "out" animations for the ViewSwitcher with your fade in and fade out so it can manage the AnimationListener implementation. Then all you need to do is alternate between the 2 ImageViews.

Edit: To be a bit more useful, here is a quick example of how to use the ViewSwitcher. I have included the full source at https://github.com/aldryd/imageswitcher.

activity_main.xml

    <ViewSwitcher
        android:id="@+id/switcher"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:inAnimation="@anim/fade_in"
        android:outAnimation="@anim/fade_out" >

        <ImageView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:scaleType="fitCenter"
            android:src="@drawable/sunset" />

        <ImageView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:scaleType="fitCenter"
            android:src="@drawable/clouds" />
    </ViewSwitcher>

MainActivity.java

    // Let the ViewSwitcher do the animation listening for you
    ((ViewSwitcher) findViewById(R.id.switcher)).setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            ViewSwitcher switcher = (ViewSwitcher) v;

            if (switcher.getDisplayedChild() == 0) {
                switcher.showNext();
            } else {
                switcher.showPrevious();
            }
        }
    });

For a field separator of any number 2 through 5 or letter a or # or a space, where the separating character must be repeated at least 2 times and not more than 6 times, for example:

awk -F'[2-5a# ]{2,6}' ...

I am sure variations of this exist using ( ) and parameters

Read up on the configuration settings (e.g., display_errors, display_startup_errors, log_errors) and update your php.ini or .htaccess or .user.ini file, whichever is appropriate.

It works.

here is my code..

const input = MobileNumberComponent.find('input')
// when
input.props().onChange({target: {
   id: 'mobile-no',
   value: '1234567900'
}});
MobileNumberComponent.update()
const Footer = (loginComponent.find('Footer'))
expect(Footer.find('Buttons').props().disabled).equals(false)

I have update my DOM with componentname.update() And then checking submit button validation(disable/enable) with length 10 digit.

{
  ...
  "scripts": {
    "start": "ENV NODE_ENV=production someapp --options"
  }
  ...
}

Here is an option. It works by using making an INDIRECT(ADDRESS(...)) from the ROW and COLUMN of the start cell, A1, down to the initial row + the number of rows held in B1.

SUM(INDIRECT(ADDRESS(ROW(A1),COLUMN(A1))):INDIRECT(ADDRESS(ROW(A1)+B1,COLUMN(A1))))

A1: is the start of data in a the "A" column

B1: is the number of rows to sum

Here is how to create the desired outcome:

library(reshape2); library(tidyverse)
melt(outer(1:4, 1:4), varnames = c("X1", "X2")) %>%
ggplot() + 
  geom_tile(aes(X1, X2, fill = value)) + 
  scale_fill_continuous(guide = guide_legend()) +
  theme(legend.position="bottom",
        legend.spacing.x = unit(0, 'cm'))+
  guides(fill = guide_legend(label.position = "bottom"))

Edit: no need for these imperfect options anymore, but I'm leaving them here for reference.

Two imperfect options that don't give you exactly what you were asking for, but pretty close (will at least put the colours together).

library(reshape2); library(tidyverse)
df <- melt(outer(1:4, 1:4), varnames = c("X1", "X2"))
p1 <- ggplot(df, aes(X1, X2)) + geom_tile(aes(fill = value))
p1 + scale_fill_continuous(guide = guide_legend()) +
 theme(legend.position="bottom", legend.direction="vertical")

p1 + scale_fill_continuous(guide = "colorbar") + theme(legend.position="bottom")

If you don't have a company, leave your name, it doesn't matter as long as both bundle id in info.plist file and the one you've submitted in iTunes Connect match.

In Bundle ID Suffix you should write full name of bundle ID.

Example:

Bundle ID suffix = thebestapp (NOT CORRECT!!!!)

Bundle ID suffix = com.awesomeapps.thebestapp (CORRECT!!)

The reason for this is explained in the Developer Portal:

The App ID string contains two parts separated by a period (.) — an App ID Prefix (your Team ID by default, e.g. ABCDE12345), and an App ID Suffix (a Bundle ID search string, e.g. com.mycompany.appname). [emphasis added]

So in this case the suffix is the full string com.awesomeapps.thebestapp.

For Flutter 1.17.3 (stable channel as of June 2020), use

FocusManager.instance.primaryFocus.unfocus();

As another option it is worth looking at react scroll component.

You don't want git revert. That undoes a previous commit. You want git checkout to get git's version of the file from master.

git checkout -- filename.txt

In general, when you want to perform a git operation on a single file, use -- filename.

• git-checkout Documentation
• git-revert Documentation

2020 Update

Git introduced a new command git restore in version 2.23.0. Therefore, if you have git version 2.23.0+, you can simply git restore filename.txt - which does the same thing as git checkout -- filename.txt. The docs for this command do note that it is currently experimental.

You can do

git config http.sslVerify "false"

in your specific repo to disable SSL certificate checking for that repo only.

Just specifying HTTPS in the URI should do the trick.

httpClient.BaseAddress = new Uri("https://foobar.com/");

If the request works with HTTP but fails with HTTPS then this is most certainly a certificate issue. Make sure the caller trusts the certificate issuer and that the certificate is not expired. A quick and easy way to check that is to try making the query in a browser.

You also may want to check on the server (if it's yours and / or if you can) that it is set to serve HTTPS requests properly.

A callback lets you pass executable code as an argument to other code. In C and C++ this is implemented as a function pointer. In .NET you would use a delegate to manage function pointers.

A few uses include error signaling and controlling whether a function acts or not.

Wikipedia

ImmediateParentClass.frotz(self)

will be just fine, whether the immediate parent class defined frotz itself or inherited it. super is only needed for proper support of multiple inheritance (and then it only works if every class uses it properly). In general, AnyClass.whatever is going to look up whatever in AnyClass's ancestors if AnyClass doesn't define/override it, and this holds true for "child class calling parent's method" as for any other occurrence!

Your first idea used to be the way but I've also noticed issues doing this using Firefox, try a straight http:// to the file - href='http://server/directory/file.xlsx'

You can do this: If your tomcat installation is default and you have not done any changes, then the default war will be ROOT.war. Thus whenever you will call http://yourserver.example.com/, it will call the index.html or index.jsp of your default WAR file. Make the following changes in your webapp/ROOT folder for redirecting requests to http://yourserver.example.com/somewhere/else:

1. Open webapp/ROOT/WEB-INF/web.xml, remove any servlet mapping with path /index.html or /index.jsp, and save.

2. Remove webapp/ROOT/index.html, if it exists.

3. Create the file webapp/ROOT/index.jsp with this line of content:

   <% response.sendRedirect("/some/where"); %>
   

   or if you want to direct to a different server,

   <% response.sendRedirect("http://otherserver.example.com/some/where"); %>
   

That's it.

@jmanning2k using a list comprehension has the downside of creating a new temporary list. The better solution would be using itertools.imap which returns an iterator

from itertools import imap
l = [1, "foo", 4 ,"bar"]
",".join(imap(str, l))

Our server calls stored procs from Java like so - works on both SQL Server 2000 & 2008:

String SPsql = "EXEC <sp_name> ?,?";   // for stored proc taking 2 parameters
Connection con = SmartPoolFactory.getConnection();   // java.sql.Connection
PreparedStatement ps = con.prepareStatement(SPsql);
ps.setEscapeProcessing(true);
ps.setQueryTimeout(<timeout value>);
ps.setString(1, <param1>);
ps.setString(2, <param2>);
ResultSet rs = ps.executeQuery();

Just as an FYI....

select * from sys.types where system_type_id = 231 gives you two rows.

(i'm not sure what this means yet but i'm 100% sure it's messing up my code right now)

edit: i guess what it means is that you should join by the user_type_id in this situation (my situation) or possibly both the user_type_id and the system_type_id

        join sys.parameters parm ON sp.object_id = parm.object_id 
        
where   sp.name = 'yyy_test'

order   by parm.parameter_id

Yields:

@col_one            -1          1
@col_two            -1          2

@col_six             256        6
@col_seven           256        7

And This:

select  parm.name as parameter,    
        parm.max_length, 
        parm.parameter_id,
        typ.name as data_type,

where   sp.name = 'yyy_test'

order   by parm.parameter_id

Gives You This:

White space affects inline elements.

This should not come as a surprise. We see it every day with span, strong and other inline elements. Set the font size to zero to remove the extra margin.

.container {
  font-size: 0px;
  letter-spacing: 0px;
  word-spacing: 0px;
}

.container > div {
  display: inline-block;
  margin: 0px;
  padding: 0px;
  font-size: 15px;
  letter-spacing: 1em;
  word-spacing: 2em;
}

The example would then look like this.

<div class="container">
  <div>First</div>
  <div>Second</div>
</div>

Yet another way this error message can occur...

If PowerShell is open in a directory other than the target file, e.g.:

If someScript.ps1 is located here: C:\SlowLearner\some_missing_path\someScript.ps1, then C:\SlowLearner>. ./someScript.ps1 wont work.

In that case, navigate to the path: cd some_missing_path then this would work:

C:\SlowLearner\some_missing_path>. ./someScript.ps1

Here is a more generic way to do the same, while supporting scopes :

// Get function from string, with or without scopes (by Nicolas Gauthier)
window.getFunctionFromString = function(string)
{
    var scope = window;
    var scopeSplit = string.split('.');
    for (i = 0; i < scopeSplit.length - 1; i++)
    {
        scope = scope[scopeSplit[i]];

        if (scope == undefined) return;
    }

    return scope[scopeSplit[scopeSplit.length - 1]];
}

Hope it can help some people out.

You can use the Java Geodesy Library for GPS, it uses the Vincenty's formulae which takes account of the earths surface curvature.

Implementation goes like this:

import org.gavaghan.geodesy.*;

...

GeodeticCalculator geoCalc = new GeodeticCalculator();

Ellipsoid reference = Ellipsoid.WGS84;  

GlobalPosition pointA = new GlobalPosition(latitude, longitude, 0.0); // Point A

GlobalPosition userPos = new GlobalPosition(userLat, userLon, 0.0); // Point B

double distance = geoCalc.calculateGeodeticCurve(reference, userPos, pointA).getEllipsoidalDistance(); // Distance between Point A and Point B

The resulting distance is in meters.

My simplest solution with Express 4.2.0 (EDIT: Doesn't seem to work in 4.3.0) was:

function supportCrossOriginScript(req, res, next) {
    res.status(200);
    res.header("Access-Control-Allow-Origin", "*");
    res.header("Access-Control-Allow-Headers", "Content-Type");

    // res.header("Access-Control-Allow-Headers", "Origin");
    // res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
    // res.header("Access-Control-Allow-Methods","POST, OPTIONS");
    // res.header("Access-Control-Allow-Methods","POST, GET, OPTIONS, DELETE, PUT, HEAD");
    // res.header("Access-Control-Max-Age","1728000");
    next();
}

// Support CORS
app.options('/result', supportCrossOriginScript);

app.post('/result', supportCrossOriginScript, function(req, res) {
    res.send('received');
    // do stuff with req
});

I suppose doing app.all('/result', ...) would work too...

You could embed your Python script in a C program and then MEX the C program with MATLAB but that might be a lot of work compared dumping the results to a file.

You can call MATLAB functions in Python using PyMat. Apart from that, SciPy has several MATLAB duplicate functions.

But if you need to run Python scripts from MATLAB, you can try running system commands to run the script and store the results in a file and read it later in MATLAB.

Thanks Burhan Khalid. Your advice to make a a soft link make my installation finally work.

To recap:

1. You need both the basic version and the SDK version of instant client

2. You need to set both LD_LIBRARY_PATH and ORACLE_HOME

3. You need to create a soft link (ln -s libclntsh.so.12.1 libclntsh.so in my case)

None of this is documented anywhere, which is quite unbelievable and quite frustrating. I spent over 3 hours yesterday with failed builds because I didn't know to create a soft link.

great code; little hint: if you sometimes have to bypass more data and not only the viewmodel ..

 if (model is ViewDataDictionary)
 {
     controller.ViewData = model as ViewDataDictionary;
 } else {
     controller.ViewData.Model = model;
 }

Using just awk you could do (I also shortened some of your piping):

strings -a libAddressDoctor5.so | awk '/EngineVersion/ { if(NR==2) { gsub("\"",""); print $2 } }'

I can't verify it for you because I don't know your exact input, but the following works:

echo "Blah EngineVersion=\"123\"" | awk '/EngineVersion/ { gsub("\"",""); print $2 }'

See also this question on removing single quotes.

Let say you have an exchange call like below:

String url = "/zzz/{accountNumber}";

Optional<AccountResponse> accResponse = Optional.ofNullable(accountNumber)
        .map(account -> {


            HttpHeaders headers = new HttpHeaders();
            headers.setContentType(MediaType.APPLICATION_JSON);
            headers.set("Authorization", "bearer 121212");


            HttpEntity<Object> entity = new HttpEntity<>(headers);
            ResponseEntity<AccountResponse> response = template.exchange(
                    url,
                    GET,
                    entity,
                    AccountResponse.class,
                    accountNumber
            );

            return response.getBody();
        });

To mock this in your test case you can use mocitko as below:

when(restTemplate.exchange(
        ArgumentMatchers.anyString(),
        ArgumentMatchers.any(HttpMethod.class),
        ArgumentMatchers.any(),
        ArgumentMatchers.<Class<AccountResponse>>any(),
        ArgumentMatchers.<ParameterizedTypeReference<List<Object>>>any())
)

if you want to open all your .cpp files with one command, and have the window split in as many tiles as opened files, you can use:

vim -o $(find name ".cpp")

if you want to include a template in the place you are, you can use:

:r ~/myHeaderTemplate 

will import the file "myHeaderTemplate in the place the cursor was before starting the command.

you can conversely select visually some code and save it to a file

1. select visually,
2. add w ~/myPartialfile.txt

when you select visualy, after type ":" in order to enter a command, you'll see "'<,'>" appear after the ":"

'<,'>w ~/myfile $

^ if you add "~/myfile" to the command, the selected part of the file will be saved to myfile.

if you're editing a file an want to copy it :

:saveas newFileWithNewName

i would advice to create table with unique name before bulk inserting.

error while loading shared libraries: libncurses.so.5

If you see this, your distro probably has a newer version of libncurse installed. First find out what version of libncurses your distro has:

$ ls -1 /usr/lib/libncurses*
/usr/lib/libncurses.so
/usr/lib/libncurses++.so
/usr/lib/libncurses++w.so
/usr/lib/libncursesw.so
/usr/lib/libncurses++w.so.6
/usr/lib/libncursesw.so.6
/usr/lib/libncurses++w.so.6.0
/usr/lib/libncursesw.so.6.0

In this case, we are dealing with version 6, so we make two symlinks:

$ sudo ln -s /usr/lib/libncursesw.so.6.0 /usr/lib/libncurses.so.5
$ sudo ln -s /usr/lib/libncursesw.so.6.0 /usr/lib/libtinfo.so.5

After this, the program should run normally.

You can override drawPlaceholderInRect:(CGRect)rect as such to manually render the placeholder text:

- (void) drawPlaceholderInRect:(CGRect)rect {
    [[UIColor blueColor] setFill];
    [[self placeholder] drawInRect:rect withFont:[UIFont systemFontOfSize:16]];
}

In brief

• Xcode 3 introduced subproject, which is parent-child relationship, meaning that parent can reference its child target, but no vice versa
• Xcode 4 introduced workspace, which is sibling relationship, meaning that any project can reference projects in the same workspace

In my case, I've depend on Snackbar#isShown() for better UX.

private Snackbar exitSnackBar;

@Override
public void onBackPressed() {
    if (isNavDrawerOpen()) {
        closeNavDrawer();
    } else if (getSupportFragmentManager().getBackStackEntryCount() == 0) {
        if (exitSnackBar != null && exitSnackBar.isShown()) {
            super.onBackPressed();
        } else {
            exitSnackBar = Snackbar.make(
                    binding.getRoot(),
                    R.string.navigation_exit,
                    2000
            );
            exitSnackBar.show();
        }
    } else {
        super.onBackPressed();
    }
}

I also had this problem today, and deleting files org.eclipse.jst.server.tomcat.core.prefs and org.eclipse.wst.server.core.prefs didn't work.

Finally I found it's permission issue:

By default <apache-tomcat-version>/conf/* can be read only by owner, after I made it readable for all, it works! So run this command:

chmod a+r <apache-tomcat-version>/conf/*

Here is the link where I found the root cause:

Edit: Use printf("val = 0x%" PRIx64 "\n", val); instead.

Try printf("val = 0x%llx\n", val);. See the printf manpage:

ll (ell-ell). A following integer conversion corresponds to a long long int or unsigned long long int argument, or a following n conversion corresponds to a pointer to a long long int argument.

Edit: Even better is what @M_Oehm wrote: There is a specific macro for that, because unit64_t is not always a unsigned long long: PRIx64 see also this stackoverflow answer

I really liked these articles:

He really dumbs down the concept in a humorous way. Worth reading.

I know that this post is a bit old but incase anyone finds it still relevant you might want to check out the free geocoding services offered by USC College. This does included address validation via ajax and static calls. The only catch is that they request a link back and only offer allotments of 2500 calls. More than fair. https://webgis.usc.edu/Services/AddressValidation/Default.aspx

Oh wow, i feel so stupid by ready all this answers, they are like experts' answer with all CTE and temp table and etc.

And all I did to get it working was simply aggregated the ID column by using MAX.

DELETE FROM table WHERE col1 IN (
    SELECT MAX(id) FROM table GROUP BY id HAVING ( COUNT(col1) > 1 )
)

NOTE: you might need to run it multiple time to remove duplicate as this will only delete one set of duplicate rows at a time.

The thread's a little old. But from the title I thought it had promise for my needs. Unfortunately, my structure didn't lend itself easily to the nth-of-type solution. Here's a Thymeleaf solution.

.back-red {
  background-color:red;
}
.back-green {
  background-color:green;
}

public static <T> List<T> toList(String json, Class<T> clazz) {
    if (null == json) {
        return null;
    }
    Gson gson = new Gson();
    return gson.fromJson(json, new TypeToken<T>(){}.getType());
}

sample call:

List<Specifications> objects = GsonUtils.toList(products, Specifications.class);

I just stumbled upon this great post. If you are just checking whether the data is of string type then maybe we can skip the loop and use this struct (in my humble opinion)

public static bool IsStringType(object data)
    {
        return (data.GetType().GetProperties().Where(x => x.PropertyType == typeof(string)).FirstOrDefault() != null);
    }

For someone having the same problem -

import name 'path' from 'django.urls' 
(C:\Python38\lib\site-packages\django\urls\__init__.py)

You can also try installing django-urls by

pipenv install django-urls

As MySql accepts the date in y-m-d format in date type column, you need to STR_TO_DATE function to convert the date into yyyy-mm-dd format for insertion in following way:

INSERT INTO table_name(today) 
VALUES(STR_TO_DATE('07-25-2012','%m-%d-%y'));  

Similary, if you want to select the date in different format other than Mysql format, you should try DATE_FORMAT function

SELECT DATE_FORMAT(today, '%m-%d-%y') from table_name; 

I thought Activity was deprecated

No.

So for API Level 22 (with a minimum support for API Level 15 or 16), what exactly should I use both to host the components, and for the components themselves? Are there uses for all of these, or should I be using one or two almost exclusively?

Activity is the baseline. Every activity inherits from Activity, directly or indirectly.

FragmentActivity is for use with the backport of fragments found in the support-v4 and support-v13 libraries. The native implementation of fragments was added in API Level 11, which is lower than your proposed minSdkVersion values. The only reason why you would need to consider FragmentActivity specifically is if you want to use nested fragments (a fragment holding another fragment), as that was not supported in native fragments until API Level 17.

AppCompatActivity is from the appcompat-v7 library. Principally, this offers a backport of the action bar. Since the native action bar was added in API Level 11, you do not need AppCompatActivity for that. However, current versions of appcompat-v7 also add a limited backport of the Material Design aesthetic, in terms of the action bar and various widgets. There are pros and cons of using appcompat-v7, well beyond the scope of this specific Stack Overflow answer.

ActionBarActivity is the old name of the base activity from appcompat-v7. For various reasons, they wanted to change the name. Unless some third-party library you are using insists upon an ActionBarActivity, you should prefer AppCompatActivity over ActionBarActivity.

So, given your minSdkVersion in the 15-16 range:

• If you want the backported Material Design look, use AppCompatActivity

• If not, but you want nested fragments, use FragmentActivity

• If not, use Activity

Just adding from comment as note: AppCompatActivity extends FragmentActivity, so anyone who needs to use features of FragmentActivity can use AppCompatActivity.

DECLARE @str AS VARCHAR(50)

git branch --set-upstream <<origin/branch>> is officially not supported anymore and is replaced by git branch --set-upstream-to <<origin/branch>>

This is my example.

https://github.com/luisnicg/jQuery-Sortable-and-PHP

You need to catch the order in the update event

    $( "#sortable" ).sortable({
    placeholder: "ui-state-highlight",
    update: function( event, ui ) {
        var sorted = $( "#sortable" ).sortable( "serialize", { key: "sort" } );
        $.post( "form/order.php",{ 'choices[]': sorted});
    }
});

If someone is using Sequel the migration would look something like:

add_column :products, :price, "decimal(8,2)"

somehow Sequel ignores :precision and :scale

(Sequel Version: sequel (3.39.0, 3.38.0))

To be clearer (as i read this thread but didn't SEE the solution, also if it was here!), I have the same problem and found the cause: I were modifying the wrong php.ini!

Yes, there are 2 php.ini files in MAMP:

1. Applications/MAMP/conf/php5.5.10/php.ini
2. Applications/MAMP/bin/php/php5.5.10/conf/php.ini

The right php.ini file is the second: Applications/MAMP/bin/php/php5.5.10/conf/php.ini

To prove this, create a .php file (call it as you like, for example "info.php") and put into it a simple phpinfo()

<?php
echo phpinfo();

Open it in your browser and search for "Loaded Configuration File": mine is "/Applications/MAMP/bin/php/php5.5.10/conf/php.ini"

The error was here; i edited Applications/MAMP/conf/php5.5.10/php.ini but this is the wrong file to modify! Infact, the right php.ini file is the one in the bin directory.

Take care of this so small difference that caused me literally 1 and a half hours of headaches!

If you are using the InternetExplorer.Application COM object, check the ReadyState property for the value of 4.

You can generate scripts to a file via SQL Server Management Studio, here are the steps:

1. Right click the database you want to generate scripts for (not the table) and select tasks - generate scripts
2. Next, select the requested table/tables, views, stored procedures, etc (from select specific database objects)
3. Click advanced - select the types of data to script
4. Click Next and finish

MSDN Generate Scripts

When generating the scripts, there is an area that will allow you to script, constraints, keys, etc. From SQL Server 2008 R2 there is an Advanced Option under scripting:

Don't use sudo in a virtual environment because it ignores the environment's variables and therefore sudo pip refers to your global pip installation.

So with your environment activated, rerun pip install boto3 but without sudo.

With regard to Brent.Longborough's answer (appering only on page 2 onward), perhaps you need to set the \thispagestyle{} after \begin{document}. I wonder if the letter class is setting the first page style to empty.

Just follow these Steps :

If you want the contents of, say, C1 to mirror the contents of cell A1, you just need to set the formula in C1 to =A1. From this point forward, anything you type in A1 will show up in C1 as well.

To Link Multiple Cells in Excel From Another Worksheet :

Step 1

Click the worksheet tab at the bottom of the screen that contains a range of precedent cells to which you want to link. A range is a block or group of adjacent cells. For example, assume you want to link a range of blank cells in “Sheet1” to a range of precedent cells in “Sheet2.” Click the “Sheet2” tab.

Step 2

Determine the precedent range’s width in columns and height in rows. In this example, assume cells A1 through A4 on “Sheet2” contain a list of numbers 1, 2, 3 and 4, respectively, which will be your precedent cells. This precedent range is one column wide by four rows high.

Step 3

Click the worksheet tab at the bottom of the screen that contains the blank cells in which you will insert a link. In this example, click the “Sheet1” tab.

Step 4

Select the range of blank cells you want to link to the precedent cells. This range must be the same size as the precedent range, but can be in a different location on the worksheet. Click and hold the mouse button on the top left cell of the range, drag the mouse cursor to the bottom right cell in the range and release the mouse button to select the range. In this example, assume you want to link cells C1 through C4 to the precedent range. Click and hold on cell C1, drag the mouse to cell C4 and release the mouse to highlight the range.

Step 5

Type “=,” the worksheet name containing the precedent cells, “!,” the top left cell of the precedent range, “:” and the bottom right cell of the precedent range. Press “Ctrl,” “Shift” and “Enter” simultaneously to complete the array formula. Each dependent cell is now linked to the cell in the precedent range that’s in the same respective location within the range. In this example, type “=Sheet2!A1:A4” and press “Ctrl,” “Shift” and “Enter” simultaneously. Cells C1 through C4 on “Sheet1” now contain the array formula “{=Sheet2!A1:A4}” surrounded by curly brackets, and show the same data as the precedent cells in “Sheet2.”

Good Luck !!!

left = None

left is None #evaluates to True

Let me answer this question:
First of all, using annotations as our configure method is just a convenient method instead of coping the endless XML configuration file.

The @Idannotation is inherited from javax.persistence.Id, indicating the member field below is the primary key of current entity. Hence your Hibernate and spring framework as well as you can do some reflect works based on this annotation. for details please check javadoc for Id

The @GeneratedValue annotation is to configure the way of increment of the specified column(field). For example when using Mysql, you may specify auto_increment in the definition of table to make it self-incremental, and then use

@GeneratedValue(strategy = GenerationType.IDENTITY)

in the Java code to denote that you also acknowledged to use this database server side strategy. Also, you may change the value in this annotation to fit different requirements.

1. Define Sequence in database

For instance, Oracle has to use sequence as increment method, say we create a sequence in Oracle:

create sequence oracle_seq;

2. Refer the database sequence

Now that we have the sequence in database, but we need to establish the relation between Java and DB, by using @SequenceGenerator:

@SequenceGenerator(name="seq",sequenceName="oracle_seq")

sequenceName is the real name of a sequence in Oracle, name is what you want to call it in Java. You need to specify sequenceName if it is different from name, otherwise just use name. I usually ignore sequenceName to save my time.

3. Use sequence in Java

Finally, it is time to make use this sequence in Java. Just add @GeneratedValue:

@GeneratedValue(strategy=GenerationType.SEQUENCE, generator="seq")

The generator field refers to which sequence generator you want to use. Notice it is not the real sequence name in DB, but the name you specified in name field of SequenceGenerator.

4. Complete

So the complete version should be like this:

public class MyTable
{
    @Id
    @SequenceGenerator(name="seq",sequenceName="oracle_seq")        
    @GeneratedValue(strategy=GenerationType.SEQUENCE, generator="seq")               
    private Integer pid;
}

Now start using these annotations to make your JavaWeb development easier.

byte[] bytes = new byte[100];

Initializes all byte elements with default values, which for byte is 0. In fact, all elements of an array when constructed, are initialized with default values for the array element's type.

Include <ctime> and use the time function.

Use switch every time you have more than 2 conditions on a single variable, take weekdays for example, if you have a different action for every weekday you should use a switch.

Other situations (multiple variables or complex if clauses you should Ifs, but there isn't a rule on where to use each.

I found the solution to my problem, I was having the same issue. Previously I had my connection string as this notice the port :3306 needs to be either attached to the server like that 127.0.0.1:3306 or removed from server like that Server=127.0.0.1;Port=3306 depending on your .NET environment:

"Server=127.0.0.1:3306;Uid=username;Pwd=password;Database=db;"

It was running fine until something happened which I am not sure exactly what it is, might be a recent update to my .NET application packages. It looks like format and spacing of the connection string is important. Anyways, the following format seems to be working for me:

"Server=127.0.0.1;Port=3306;Uid=username;Pwd=password;Database=db;"

Try either of the versions and see which one works for you.

Also I noticed that you are not using camel casing, this could be it. Make sure your property names are in capital casing like that

Server
Port
Uid
Pwd
Database

Within your app in the Android Emulator press Command + M on macOS or Ctrl + M on Linux and Windows.

You can also use the DeleteAllOnSubmit() method by passing it your results in a generic list rather than in var. This way your foreach reduces to one line of code:

List<Widgets> widgetList = context.Widgets
              .Where(w => w.WidgetId == widgetId).ToList<Widgets>();

context.Widgets.DeleteAllOnSubmit(widgetList);

context.SubmitChanges();

It probably still uses a loop internally though.

As I parse it, those words are wrong. It should read "If the function modifies that value, the modifications appear also within the scope of the calling function when passing by reference, but not when passing by value."

Complete working example in Kotlin, I have replaced my API keys with 1111...

        val apiService = API.getInstance().retrofit.create(MyApiEndpointInterface::class.java)
        val params = HashMap<String, String>()
        params["q"] =  "munich,de"
        params["APPID"] = "11111111111111111"

        val call = apiService.getWeather(params)

        call.enqueue(object : Callback<WeatherResponse> {
            override fun onFailure(call: Call<WeatherResponse>?, t: Throwable?) {
                Log.e("Error:::","Error "+t!!.message)
            }

            override fun onResponse(call: Call<WeatherResponse>?, response: Response<WeatherResponse>?) {
                if (response != null && response.isSuccessful && response.body() != null) {
                    Log.e("SUCCESS:::","Response "+ response.body()!!.main.temp)

                    temperature.setText(""+ response.body()!!.main.temp)

                }
            }

        })

A possible soluttion that requires tweaking, but is very flexible is to use one of \big, \Big, \bigg,\Bigg in front of your division sign - these will make it progressively larger. For your formula, I think

  $\frac{a_1}{a_2} \Big/ \frac{b_1}{b_2}$

looks nicer than \middle\ which is automatically sized and IMHO is a bit too large.

Default arguments must be specified with the first occurrence of the function name—typically, in the function prototype. If the function prototype is omitted because the function definition also serves as the prototype, then the default arguments should be specified in the function header.

Starting with C# 8.0, you can create and consume streams asynchronously.

    private async void button1_Click(object sender, EventArgs e)
    {
        IAsyncEnumerable<int> enumerable = GenerateSequence();

        await foreach (var i in enumerable)
        {
            Debug.WriteLine(i);
        }
    }

    public static async IAsyncEnumerable<int> GenerateSequence()
    {
        for (int i = 0; i < 20; i++)
        {
            await Task.Delay(100);
            yield return i;
        }
    }

Current best practice in CSS development is to create more general selectors with modifiers that can be applied as widely as possible throughout the web site. I would try to avoid defining separate styles for individual page elements.

If the purpose of the CSS class on the <form/> element is to control the style of elements within the form, you could add the class attribute the existing <fieldset/> element which encapsulates any form by default in web pages generated by ASP.NET MVC. A CSS class on the form is rarely necessary.

Add a column to the query which can sub identify the data to sort on that.

In the below example I use a Common Table Expression with the selects you showed which places them in specific groups in the CTE, and then do a union off of both of those groups into AllStudents.

The final select will then sort AllStudents by the SortIndex column first and then by the name such as:

WITH Juveniles as
(
      Select 1 as [SortIndex], id,name,age From Student
      Where age < 15
),

AStudents as
(
      Select 2 as [SortIndex], id,name,age From Student
      Where Name like "%a%" 
),

AllStudents as
(
      select * from Juveniles
      union 
      select * from AStudents
)

select * from AllStudents
sort by [SortIndex], name;

To summarize, it will get all the students which will be sorted by group first, and subsorted by the name within the group after that.

If you have your dates in DateTime variables, they don't have a format.

You can use the Date property to return a DateTime value with the time portion set to midnight. So, if you have:

DateTime dt1 = DateTime.Parse("07/12/2011");
DateTime dt2 = DateTime.Now;

if(dt1.Date > dt2.Date)
{
     //It's a later date
}
else
{
     //It's an earlier or equal date
}

I add credentials for HttpWebRequest.

myReq.UseDefaultCredentials = true;
myReq.PreAuthenticate = true;
myReq.Credentials = CredentialCache.DefaultCredentials;

In command prompt:

SET PATH = "%PATH%;%SystemRoot%\Microsoft.NET\Framework\v2.0.50727"

Another way starting from c# 7.0 would be using local functions. You could name the local function with a meaningful name, and call it directly before declaring it (for clarity). Here is your example rewritten:

public void Method()
{
    // Some code here
    bool something = true, something2 = true;

    DoSomething();
    void DoSomething()
    {
        if (something)
        {
            //some code
            if (something2)
            {
                // now I should break from ifs and go to te code outside ifs
                return;
            }
            return;
        }
    }

    // The code i want to go if the second if is true
    // More code here
}

You can use jconsole (standard with most JDKs) to check heap sizes of any java process.

I have created usable extension for UIView to take screenshot in Swift:

extension UIView{

var screenshot: UIImage{

    UIGraphicsBeginImageContext(self.bounds.size);
    let context = UIGraphicsGetCurrentContext();
    self.layer.renderInContext(context)
    let screenShot = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    return screenShot
}
}

To use it just type:

let screenshot = view.screenshot

You also can get it from any ContainerAware (f.i. Controller) class from the request service:

• If you are using apache as a webserver (I suppose for other webservers the solution would be similar) and are using virtualhosting (your urls look like this - localhost/app.php then you can use:

  $container->get('request')->server->get('DOCUMENT_ROOT');
  // in controller:
  $this->getRequest()->server->get('DOCUMENT_ROOT');
  

• Else (your urls look like this - localhost/path/to/Symfony/web/app.php:

  $container->get('request')->getBasePath();
  // in controller:
  $this->getRequest()->getBasePath();
  

FYI, it's not terribly difficult to make a list that has a push method:

>>> class StackList(list):
...     def push(self, item):
...             self.append(item)
... 
>>> x = StackList([1,2,3])
>>> x
[1, 2, 3]
>>> x.push(4)
>>> x
[1, 2, 3, 4]

A stack is a somewhat abstract datatype. The idea of "pushing" and "popping" are largely independent of how the stack is actually implemented. For example, you could theoretically implement a stack like this (although I don't know why you would):

l = [1,2,3]
l.insert(0, 1)
l.pop(0)

...and I haven't gotten into using linked lists to implement a stack.

How about this:

List<SubProduct> subProducts = Model.subproduct.ToList();

Windows 7 has the arp command within it. arp -a should show you the static and dynamic type interfaces connected to your system.

First remove the rows which contain NaN. Then do Integer conversion on remaining rows. At Last insert the removed rows again. Hope it will work

If you are using numpy, the closest, I can think of is using a mask

>>> import numpy as np
>>> arr = np.arange(1,10)
>>> mask = np.ones(arr.shape,dtype=bool)
>>> mask[5]=0
>>> arr[mask]
array([1, 2, 3, 4, 5, 7, 8, 9])

Something similar can be achieved using itertools without numpy

>>> from itertools import compress
>>> arr = range(1,10)
>>> mask = [1]*len(arr)
>>> mask[5]=0
>>> list(compress(arr,mask))
[1, 2, 3, 4, 5, 7, 8, 9]

Use apt to uninstall and remove all MySQL packages:

$ sudo apt-get remove --purge mysql-server mysql-client mysql-common -y
$ sudo apt-get autoremove -y
$ sudo apt-get autoclean

Remove the MySQL folder:

 $ rm -rf /etc/mysql

Delete all MySQL files on your server:

$ sudo find / -iname 'mysql*' -exec rm -rf {} \;

Your system should no longer contain default MySQL related files.

For posix (Linux, BSD, etc... only need /proc directory to be mounted) it's easier to work with os files in /proc. It's pure python, no need to call shell programs outside.

Works on python 2 and 3 ( The only difference (2to3) is the Exception tree, therefore the "except Exception", which I dislike but kept to maintain compatibility. Also could've created a custom exception.)

#!/usr/bin/env python

import os
import sys


for dirname in os.listdir('/proc'):
    if dirname == 'curproc':
        continue

    try:
        with open('/proc/{}/cmdline'.format(dirname), mode='rb') as fd:
            content = fd.read().decode().split('\x00')
    except Exception:
        continue

    for i in sys.argv[1:]:
        if i in content[0]:
            print('{0:<12} : {1}'.format(dirname, ' '.join(content)))

Sample Output (it works like pgrep):

phoemur ~/python $ ./pgrep.py bash
1487         : -bash 
1779         : /bin/bash

As others have said, there is no way to do a single line comment legally in XML that comments out multiple lines, but, there are ways to make commenting out segments of XML easier.

Looking at the example below, if you add '>' to line one, the XmlTag will be uncommented. Remove the '>' and it's commented out again. This is the simplest way that I've seen to quickly comment/uncomment XML without breaking things.

<!-- --
<XmlTag variable="0" />
<!-- -->

The added benefit is that you only manipulate the top comment, and the bottom comment can just sit there forever. This breaks compatibility with SGML and some XML parsers will barf on it. So long as this isn't a permanent fixture in your XML, and your parsers accept it, it's not really a problem.

Stack Overflow's and Notepad++'s syntax highlighter treat it like a multi-line comment, C++'s Boost library treats it as a multi-line comment, and the only parser I've found so far that breaks is the one in .NET, specifically C#. So, be sure to first test that your tools, IDE, libraries, language, etc. accept it before using it.

If you care about SGML compatibility, simply use this instead:

<!-- -
<XmlTag variable="0" />
<!- -->

Add '->' to the top comment and a '-' to the bottom comment. The downside is having to edit the bottom comment each time, which would probably make it easier to just type in <!-- at the top and --> at the bottom each time.

I also want to mention that other commenters recommend using an XML editor that allows you to right-click and comment/uncomment blocks of XML, which is probably preferable over fancy find/replace tricks (it would also make for a good answer in itself, but I've never used such tools. I just want to make sure the information isn't lost over time). I've personally never had to deal with XML enough to justify having an editor fancier than Notepad++, so this is totally up to you.

I ran into this in IntelliJ and fixed it by adding the following to my pom:

<!-- logging dependencies -->
    <dependency>
        <groupId>ch.qos.logback</groupId>
        <artifactId>logback-classic</artifactId>
        <version>${logback.version}</version>
        <exclusions>
            <exclusion>
                <!-- Defined below -->
                <artifactId>slf4j-api</artifactId>
                <groupId>org.slf4j</groupId>
            </exclusion>
        </exclusions>
    </dependency>

    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-api</artifactId>
        <version>${slf4j.version}</version>
    </dependency>

As denoted in other answers, sets are data structures (and mathematical concepts) that do not preserve the element order -

However, by using a combination of sets and dictionaries, it is possible that you can achieve wathever you want - try using these snippets:

# save the element order in a dict:
x_dict = dict(x,y for y, x in enumerate(my_list) )
x_set = set(my_list)
#perform desired set operations
...
#retrieve ordered list from the set:
new_list = [None] * len(new_set)
for element in new_set:
   new_list[x_dict[element]] = element

The point is semantics. In assertTrue, you are asserting that the expression is true. If it is not, then it will display the message and the assertion will fail. In assertFalse, you are asserting that an expression evaluates to false. If it is not, then the message is displayed and the assertion fails.

assertTrue (message, value == false) == assertFalse (message, value);

These are functionally the same, but if you are expecting a value to be false then use assertFalse. If you are expecting a value to be true, then use assertTrue.

Try this JS function, passing the span element as argument:

function isEllipsisActive(e) {
     return (e.offsetWidth < e.scrollWidth);
}

I had to include -lmysqlcppconn to my build in order to get it to work.

Or if you use gmaps.js, call:

map.refresh();

when your div is shown.

Referencing Bash Variables Requires Parameter Expansion

The default shell on most Linux distributions is Bash. In Bash, variables must use a dollar sign prefix for parameter expansion. For example:

x=20
y=5
expr $x / $y

Of course, Bash also has arithmetic operators and a special arithmetic expansion syntax, so there's no need to invoke the expr binary as a separate process. You can let the shell do all the work like this:

x=20; y=5
echo $((x / y))

I made a dynamic proc which turns any random query into an HTML table, so you don't have to hardcode columns like in the other responses.

-- Description: Turns a query into a formatted HTML table. Useful for emails. 
-- Any ORDER BY clause needs to be passed in the separate ORDER BY parameter.
-- =============================================
CREATE PROC [dbo].[spQueryToHtmlTable] 
(
  @query nvarchar(MAX), --A query to turn into HTML format. It should not include an ORDER BY clause.
  @orderBy nvarchar(MAX) = NULL, --An optional ORDER BY clause. It should contain the words 'ORDER BY'.
  @html nvarchar(MAX) = NULL OUTPUT --The HTML output of the procedure.
)
AS
BEGIN   
  SET NOCOUNT ON;

  IF @orderBy IS NULL BEGIN
    SET @orderBy = ''  
  END

  SET @orderBy = REPLACE(@orderBy, '''', '''''');

  DECLARE @realQuery nvarchar(MAX) = '
    DECLARE @headerRow nvarchar(MAX);
    DECLARE @cols nvarchar(MAX);    

    SELECT * INTO #dynSql FROM (' + @query + ') sub;

    SELECT @cols = COALESCE(@cols + '', '''''''', '', '''') + ''['' + name + ''] AS ''''td''''''
    FROM tempdb.sys.columns 
    WHERE object_id = object_id(''tempdb..#dynSql'')
    ORDER BY column_id;

    SET @cols = ''SET @html = CAST(( SELECT '' + @cols + '' FROM #dynSql ' + @orderBy + ' FOR XML PATH(''''tr''''), ELEMENTS XSINIL) AS nvarchar(max))''    

    EXEC sys.sp_executesql @cols, N''@html nvarchar(MAX) OUTPUT'', @html=@html OUTPUT

    SELECT @headerRow = COALESCE(@headerRow + '''', '''') + ''<th>'' + name + ''</th>'' 
    FROM tempdb.sys.columns 
    WHERE object_id = object_id(''tempdb..#dynSql'')
    ORDER BY column_id;

    SET @headerRow = ''<tr>'' + @headerRow + ''</tr>'';

    SET @html = ''<table border="1">'' + @headerRow + @html + ''</table>'';    
    ';

  EXEC sys.sp_executesql @realQuery, N'@html nvarchar(MAX) OUTPUT', @html=@html OUTPUT
END
GO

Usage:

DECLARE @html nvarchar(MAX);
EXEC spQueryToHtmlTable @html = @html OUTPUT,  @query = N'SELECT * FROM dbo.People', @orderBy = N'ORDER BY FirstName';

EXEC msdb.dbo.sp_send_dbmail
    @profile_name = 'Foo',
    @recipients = '[email protected];',
    @subject = 'HTML email',
    @body = @html,
    @body_format = 'HTML',
    @query_no_truncate = 1,
    @attach_query_result_as_file = 0;

Related: Here is similar code to turn any arbitrary query into a CSV string.

It is also possible to create a div element in the following way:

var my_div = document.createElement('div');

add class

my_div.classList.add('col-10');

also can perform append() and appendChild()

In fact in the last answer String strAsciiTab = Character.toString((char) iAsciiValue); the essential part is (char)iAsciiValue which is doing the job (Character.toString useless)

Meaning the first answer was correct actually char ch = (char) yourInt;

if in yourint=49 (or 0x31), ch will be '1'

Use DateTime.ToString with the specified format MM.dd.yyyy:

this.TextBox3.Text = DateTime.Now.ToString("MM.dd.yyyy");

Here, MM means the month from 01 to 12, dd means the day from 01 to 31 and yyyy means the year as a four-digit number.

override func viewDidLoad() {
    super.viewDidLoad()

    let tap = UITapGestureRecognizer(target: self, action: #selector(handleScreenTap(sender:)))
    self.view.addGestureRecognizer(tap)}

then you use this function

func handleScreenTap(sender: UITapGestureRecognizer) {
    self.view.endEditing(true)
}

var mydiv = $("#scroll");
mydiv.scrollTop(mydiv.prop("scrollHeight"));

The easiest way is to not store the count, relying on the COUNT aggregate function to reflect the value as it is in the database:

   SELECT c.category_name,
          COUNT(p.post_id) AS num_posts
     FROM CATEGORY c
LEFT JOIN POSTS p ON p.category_id = c.category_id

You can create a view to house the query mentioned above, so you can query the view just like you would a table...

But if you're set on storing the number, use:

UPDATE CATEGORY
   SET count = count + 1
 WHERE category_id = ?

..replacing "?" with the appropriate value.

Attached properties to the rescue:

    private static void ShowPlaceholder(TextBox textBox)
    {
        if (string.IsNullOrWhiteSpace(textBox.Text))
        {
            textBox.Text = GetPlaceholder(textBox);
        }
    }

    private static void HidePlaceholder(TextBox textBox)
    {
        string placeholderText = GetPlaceholder(textBox);

        if (textBox.Text == placeholderText)
            textBox.Text = string.Empty;
    }
}

Usage:

<TextBox Text="hi" local:TextboxExtensions.Placeholder="Hello there"></TextBox>

This problem is solved easily with moment.js, like this example:

var difference = mostDate.diff(minorDate, "minutes");

The second parameter can be changed for another parameters, see the moment.js documentation.

e.g.: "days", "hours", "minutes", etc.

The CDN for moment.js is available here:

Thanks.

EDIT:

mostDate and minorDate should be a moment type.

EDIT 2:

For those who are reading my answer in 2020+, momentjs is now a legacy project.

If you are still looking for a well-known library to do this job, I would recommend date-fns.

// How many minutes are between 2 July 2014 12:07:59 and 2 July 2014 12:20:00?
var result = differenceInMinutes(
  new Date(2014, 6, 2, 12, 20, 0),
  new Date(2014, 6, 2, 12, 7, 59)
)
//=> 12

It's not smart to have python code inside java. Wrap your python code with flask or other web framework to make it as a microservice. Make your java program able to call this microservice (e.g. via REST).

Beleive me, this is much simple and will save you tons of issues. And the codes are loosely coupled so they are scalable.

Updated on Mar 24th 2020: According to @stx's comment, the above approach is not suitable for massive data transfer between client and server. Here is another approach I recommended: Connecting Python and Java with Rust(C/C++ also ok). https://medium.com/@shmulikamar/https-medium-com-shmulikamar-connecting-python-and-java-with-rust-11c256a1dfb0

One way would be to first flatten the list with a SelectMany:

subList.SelectMany(m => m).Where(k => k.Key.Equals("valueTitle"));

Go to root folder

Right Click, click on Properties

Choose Tab Security

Click on Edit

Click on Add

Type 'EveryOne'

Click OK

Check Out Full Control

Click OK

If this is the current url use window.location.pathname otherwise use this regular expression:

var reg = /.+?\:\/\/.+?(\/.+?)(?:#|\?|$)/;
var pathname = reg.exec( 'http://www.somedomain.com/account/search?filter=a#top' )[1];

I had exactly the same problem with my website. I have a page that is displayed on a projector, on walls, big screens..

As I don't know the max size of my font, I re-used the plugin above of @GeekMonkey but incrementing the fontsize :

$.fn.textfill = function(options) {
        var defaults = { innerTag: 'span', padding: '10' };
        var Opts = jQuery.extend(defaults, options);

        return this.each(function() {
            var ourText = $(Opts.innerTag + ':visible:first', this);
            var fontSize = parseFloat(ourText.css('font-size'),10);
            var doNotTrepass = $(this).height()-2*Opts.padding ;
            var textHeight;

            do {
                ourText.css('font-size', fontSize);
                textHeight = ourText.height();
                fontSize = fontSize + 2;
            } while (textHeight < doNotTrepass );
        });
    };

I believe you want to set the backdrop value to static. If you want to avoid the window to close when using the Esc key, you have to set another value.

Example:

<a data-controls-modal="your_div_id"
   data-backdrop="static"
   data-keyboard="false"
   href="#">

OR if you are using JavaScript:

$('#myModal').modal({
  backdrop: 'static',
  keyboard: false
});

Yes. See the relevant page on the R wiki. Short answer: read.xls from the gdata package works most of the time (although you need to have Perl installed on your system -- usually already true on MacOS and Linux, but takes an extra step on Windows, i.e. see http://strawberryperl.com/). There are various caveats, and alternatives, listed on the R wiki page.

The only reason I see not to do this directly is that you may want to examine the spreadsheet to see if it has glitches (weird headers, multiple worksheets [you can only read one at a time, although you can obviously loop over them all], included plots, etc.). But for a well-formed, rectangular spreadsheet with plain numbers and character data (i.e., not comma-formatted numbers, dates, formulas with divide-by-zero errors, missing values, etc. etc. ..) I generally have no problem with this process.

The solution is pretty easy actually:

<button style="border:1px solid black; background-color: transparent;">Test</button>

This is doing an inline style. You're defining the border to be 1px, solid line, and black in color. The background color is then set to transparent.

UPDATE

Seems like your ACTUAL question is how do you prevent the border after clicking on it. That can be resolved with a CSS pseudo selector: :active.

button {
    border: none;
    background-color: transparent;
    outline: none;
}
button:focus {
    border: none;
}

JSFiddle Demo

According to the React Documentation it's perfectly OK to call setState() from within the componentDidMount() function.

It will cause render() to be called twice, which is less efficient than only calling it once, but other than that it's perfectly fine.

You can find the documentation here:

https://reactjs.org/docs/react-component.html#componentdidmount

Here is the excerpt from the documentation:

You may call setState() immediately in componentDidMount(). It will trigger an extra rendering, but it will happen before the browser updates the screen. This guarantees that even though the render() will be called twice in this case, the user won’t see the intermediate state. Use this pattern with caution because it often causes performance issues...
