d9401 | train | I believe passing such parameter to IFrame should be done on the page on server. Not with javascript.
According to full scenario this is what should have worked but it is not. I believe the managedbean scope is lost and that is why the id is not set on different page. To make this work probably the scope of managed bean should be session not request or view because you go to different page.
A: So, after some digging into BI Publisher, found out that parameter can just be passed through url and to iframe. In other words, url should look somewhat like this: "content:port?accessmode&credentials¶meterid". | unknown | |

d9403 | train | The easiest way to do that is by accessing the menu item. Using AXUIElementCopyAttributeValue works best with the provided constants:
// get menu bar
var menuBarPtr: CFTypeRef?
_ = AXUIElementCopyAttributeValue(safariElement, kAXMenuBarRole as CFString, &menuBarPtr)
guard let menuBarElement = menuBarPtr as! AXUIElement? else {
fatalError()
}
Accessibility Inspector shows me, what items are child of the menu bar:
so lets get the children using kAXChildrenAttribute:
// get menu bar items
var menuBarItemsPtr: CFTypeRef?
_ = AXUIElementCopyAttributeValue(menuBarElement, kAXChildrenAttribute as CFString, &menuBarItemsPtr)
guard let menuBarItemsElement = menuBarItemsPtr as AnyObject as! [AXUIElement]? else {
fatalError()
}
And so on all the way down to the menu item. Items also have an unique identifier that can look like _NS:1008. I'm not sure how to access them directly but by using AXUIElementPerformAction I can simply simulate pressing the menu item (action will be kAXPressAction).
I can use kAXRoleAttribute to identify the type of the item and where it occurs in the Accessibility hierarchy (see "Role:")
As I'm still a beginner at Swift, that was a quite challenging task as this is also not documented very well. Thanks a lot to Dexter who also helped me to understand this topic: kAXErrorAttributeUnsupported when querying Books.app
A: In your case you don't need necessarily need to use AXUI accessibility API. It's arguably simpler to send key strokes. You can go back in Safari history to previous page with CMD[. As an added bonus Safari does not need to be in foreground anymore.
let pid: pid_t = win.getSafariPid();
let leftBracket: UInt16 = 0x21
let src = CGEventSource(stateID: CGEventSourceStateID.hidSystemState)
let keyDownEvent = CGEvent(keyboardEventSource: src, virtualKey: leftBracket, keyDown: true)
keyDownEvent?.flags = CGEventFlags.maskCommand
let keyUpEvent = CGEvent(keyboardEventSource: src, virtualKey: leftBracket, keyDown: false)
keyDownEvent?.postToPid(pid)
keyUpEvent?.postToPid(pid)
Your app running on Mojave and newer MacOS versions will need the System Preferences -> Security & Privacy -> Accessibility permisions granted to be eligible for sending keystrokes to other apps.

d9404 | train | Instead of Array#filter, you could use Array#find and take the object directly without later having a look up for the index.
If found just add both wanted properties price and total.
If you like not to mutate the original data, you could take a copy of the object for pushing.
a.push({ ...c });

A: You wrote:
char oldname[] = "VMin.c_str()";
char newname[] = "outpath.c_str()";
but you probably meant to do:
char oldname* = VMin.c_str();
char newname* = outpath.c_str();
The first variant will look for a file which is called "VMin.c_str()" which does not exist and thus you are getting this error. You accidentally have put C++ code into quotes. Quotes are only for verbatim strings, like messages and fixed filenames. But your filenames are determined programmatically.
You can use the const char * c and d you are calculating above and pass these to rename(). | unknown | |

d9410 | train | You should go with Composition. I don't think Inheritance makes sense because these are completely different type of entities and really one cannot inherit from the other. What fields will they inherit? And who inherits from whom?
The BLL will need to pass the list of 'fields' to get to the DSL. Either as parameters to the DSL methods or in some other way. The DSL methods just receive some list of fields as parameters and work with them. I think that is a feasible solution.
Also, you should create Interfaces at each Layer and program against them instead of using the type itself. So for e.g, in the sample code that you wrote, change DBL and WSB to IDBL and IWSB. This will help you test better and allow for loose coupling in the code.
public class DSL
{
private IDBL _dbLayer;
private IWSB _wsBuffer;
....
}
A: In general, inheritance should be used when you have an 'Is-A' relationship. Since you cannot say BLL 'Is-A' DSL or DSL 'Is-A' DBL, then I would be looking at composition over inheritance. This has the side effect of making testing each logical layer easier because you can stub or mock each dependency.
Typically, in any exposed API, the server side (so DSL in terms of BLL -> DSL), would need to expose objects to do its work. You are right in pointing out that DSL should not know about BLL objects. So the challenge is to write a clean API for the DSL that is exposed to BLL for querying data.
I would suggest looking at both the Repository and Specification patterns from DDD. These help to solve some of the issues that you are bringing up.
A: Composition.
Because of everything that dtryon and desigeek have said and also
because in your case Inheritance looks unnatural + it will make all your
layers tightly coupled and will hardly limit making of any amends to source code.
I believe it could be helpful to take a look at prefer-composition-over-inheritance SO-topic. | unknown | |

d9412 | train | Solved. There was another similar statement further down which was over riding this one! How stupid of me but easy to miss!
A: use mysql_error to try and find what is wrong, then post that into here so we can help if you need it. (Would comment but to low rep)
A: From my experience in the past, mysql_query() doesn't necessarily substitute variables before executing sql. Try writing in this format. Also use mysql_error to check if there are any issues with your code execution:
$sql = "UPDATE my_users SET lastlogin=NOW() WHERE id=".$_SESSION["id"];
mysql_query($sql) or die(mysql_error());
If there is no error, then there are few possibilities as to why the laslogin entry is not happening:
*
*$_SESSION["id"] does not hold any value and no value is being passed to mysql.
*There is no id matching with $_SESSION["id"].
To debug:
*
*Also try updating some other columns.
*You might also want to check if you are using correct extensions like PDO..
Also found that, earlier version of mysql doesn't support updating datetime column with now(). In that case try resetting column type to TIMESTAMP. Refer this for details: https://bugs.mysql.com/bug.php?id=27645 | unknown | |

d9414 | train | Based on the question it sounds like you would like to calculate the distance between all pairs of points. Scipy has built in functionality to do this.
My suggestion is to first write a function that calcuates distance. Or use an exisitng one like the one in geopy mentioned in another answer.
def get_distance(point1, point2):
R = 6370
lat1 = radians(point1[0]) #insert value
lon1 = radians(point1[1])
lat2 = radians(point2[0])
lon2 = radians(point2[1])
dlon = lon2 - lon1
dlat = lat2- lat1
a = sin(dlat / 2)**2 + cos(lat1) * cos(lat2) * sin(dlon / 2)**2
c = 2 * atan2(sqrt(a), sqrt(1-a))
distance = R * c
return distance
Then you can pass this function into scipy.spatial.distance.cdist
all_points = df[[latitude_column, longitude_column]].values
dm = scipy.spatial.distance.cdist(all_points,
all_points,
get_distance)
As a bonus you can convert the distance matrix to a data frame if you wish to add the index to each point:
pd.DataFrame(dm, index=df.index, columns=df.index)
NOTE: I realized I am assuming, possibly incorrectly that you are using pandas
A: If you don't mind importing a few libraries, this can be done very simply.
With pandas, you can read your text file into a dataframe, which makes working with tabular data like this super easy.
import pandas as pd
df = pd.read_csv('YOURFILENAME.txt', delimiter=' ', header=None, names=('latitude', 'longitude'))
Then you can use the geopy library to calculate the distance.
A: Another solution is using the haversine equation with numpy to read in the data and calculate the distances. Any of the previous answers will also work using the other libraries.
import numpy as np
#read in the file, check the data structure using data.shape()
data = np.genfromtxt(fname)
#Create the function of the haversine equation with numpy
def haversine(Olat,Olon, Dlat,Dlon):
radius = 6371. # km
d_lat = np.radians(Dlat - Olat)
d_lon = np.radians(Dlon - Olon)
a = (np.sin(d_lat / 2.) * np.sin(d_lat / 2.) +
np.cos(np.radians(Olat)) * np.cos(np.radians(Dlat)) *
np.sin(d_lon / 2.) * np.sin(d_lon / 2.))
c = 2. * np.arctan2(np.sqrt(a), np.sqrt(1. - a))
d = radius * c
return d
#Call function with your data from some specified point
haversine(10,-110,data[:,1],data[:,0])
In this case, you can pass a single number for Olat,Olon and an array for Dlat,Dlon or vice versa and it will return an array of distances.
For example:
haversine(20,-110,np.arange(0,50,5),-120)
OUTPUT

d9418 | train | I don't think there's anything you can do as far as changing the signed version parameter.
My guess is that the implementation to generate SAS via Storage Resource Provider API makes use of Storage REST API version 2015-04-05 (signed version parameter) and if you look at request body parameters, you will notice that there's no parameter to specify the signed version parameter in the request.

d9421 | train | No, C doesn't have anything like that. If you can use C++, there's std::list.
You'll have to write the structure yourself in C.
A: As others have said, there is no standard library support for linked lists in C. That means you either get to roll your own (like most people have done at one or more times in their C coding career), or you look at other libraries for support.
For most uses, you will find that an 'intrusive' implementation is appropriate. You modify your existing structure to include a pointer to the next item in the list (and, if you're doing a doubly linked list, the previous item).
typedef struct TheStruct TheStruct;
struct TheStruct
{
...the real data...
TheStruct *next;
//TheStruct *prev;
};
Your list now consists of a simple pointer to the head item:
TheStruct *head = 0;
TheStruct *allocated_node = new_TheStruct(value1, value2, ...);
assert(allocated_node->next == 0);
// Insert new allocated node at head of list
allocated_node->next;
head = allocated_node;
You have to worry about threading issues if you've got threads access the same list, and so on and so forth.
Because this code is so simple, this is how it is most frequently handled. Deleting a node from a list is trickier, but you can write a function to do it.
People have dressed up this basic scheme with macros of varying degrees of complexity so that the code manipulating different types of lists can use the same macros. The Linux kernel uses a macro-based set of linked lists for managing its linked list data structures.
The alternative to the 'intrusive' implementation (which is so-called because it requires a change to the structure to include the list pointers) is to have some generic list mechanism:
typedef struct GenericList GenericList;
struct GenericList
{
void *data;
GenericList *next;
//GenericList *prev;
};
Now you have the ability to put (pointers to) unmodified structures into the list. You lose some type safety; there is nothing to stop you adding random different structure types to a list that should be homogeneous. You also have to allocate memory for the GenericList structures separately from the pointed at data.
*
*One advantage of this is that a single data item can be on multiple separate lists simultaneously. * One disadvantage of this is that a single data item can accidentally be on multiple lists, or multiple times in a single list, simultaneously.
You also have to make sure you understand the ownership properties for the data, so that the data is released properly (not leaked, not multiply-freed, not accessed after being freed). Managing the memory for the list itself is child's play by comparison.
With the GenericList mechanism, you will likely have a library of functions that manage the list operations for you. Again, searching should reveal implementations of such lists.
A: C does not (as yet) provide any standard container structures. You'll have to roll your own.
A: It doesn't exist by default, but it can be made quite easily.
Basically a linked list is a header pointer that points to 1st element, and an ending file pointing to null.
The elements are actually nodes, containing the object and a pointer to the next node.
So making a basic one is quite easy, though in C it might be painful as no classes, only structs.
A: There are no Lists in the standard C library. A very good C library you can use is PBL - The Program Base Library here. Its interface is Java like. You can download it from here | unknown | |

d9425 | train | I faced the similar problem. The jar was locked because the server was running using that jar. Terminating the server worked. | unknown | |
d9426 | train | I get your question right, you have x and y as window space (and already converted to normalized device space [-1,1]), but z in eye space, and want to recosntruct the world space position.
I can't have access to other (I can't use near, far, left, right, ...)
because projection matrix is not restricted to perspective or
orthogonal.
Well, actually, there is not much besides an orthogonal or projective mapping which can be achieved by matrix multiplication in homogenous space. However, the projection matrix is sufficient, as long as it is invertible (In theory, a projection matrix could transform all points to a plane, line or a single point. In that case, some information is lost and it will never be able to reconstruct the original data. But that would be a very untypical case).
So what you can get from the projection matrix and your 2D position is actually a ray in eye space. And you can intersect this with the z=depth plane to get the point back.
So what you have to do is calculate the two points
vec4 p = inverse(uProjMatrix) * vec4 (ndc_x, ndc_y, -1, 1);
vec4 q = inverse(uProjMatrix) * vec4 (ndc_x, ndc_y, 1, 1);
which will mark two points on the ray in eye space. Do not forget to divide p and q by the respective w component to get the 3D coordinates. Now, you simply need to intersect this with your z=depth plane and get the eye space x and y. Finally, you can use the inverse of the uModelView matrix to project that point back to object space.
However, you said that you want world space. But that is impossible. You would need the view matrix to do that, but you have not listed that as a given. All you have is the compisition of the model and view matrix, and you need to know at least one of these to reconstruct the world space position. The cameraPosition is not enoguh. You also need the orientation. | unknown | |

For some reason it worked again.
To be sure I deleted the plist from the document folder and cleared all targets.
And now the Problem as before I can only write the plist when i write the dictionary to it but then i can only save the last one.
And reading the plist won't work either.
Can anyone Tell me why this happens and how I can solve it?
Edit 2:
I found the Problem: since X-Code won't create the plist when I write the array with the dictionary to the plist.When I wrote the dictionary to the plist so X-Code creates the plist but with a dictionary Root so I cant write the array to it and I also can't read it in an Array.....
I created a plist in the Resources folder with a Array Root and copy it when it not exist to document folder and now it works.....

d9428 | train | if you want to skip the spot instance all you need to do this is figure out which one is spot instance.
You need to use describe_instances api and then using if-else condition, request_id is empty its a spot instance, if not then its not a spot instance
import boto3
ec2 = boto3.resource('ec2')
instances = ec2.instances.filter(Filters=[{'Name': 'instance-state-name', 'Values': ['running']}]) #add filter of your own choice
for instance in instances:
if instance.spot_instance_request_id:
# logic to skip termination ( spot instance )
else:
# logic to terminate ( not spot instance )

Steps to install:
*
*Go to file->settings->plugins
*search for json to kotlin and install
*now just like you make a new file there will be a new option paste your json and give it a name and now it automatically generates a model for you.
*Also I will recommend you to watch some tutorials on youtube, my favorite content creator is Philip Lackener he has a very good tutorial on roomdb
I am also new to android development so i get it.
I recommend you to go through a beginner playlist it will really help you get the basics. you also need to see basics of roomdb because what you are asking is really basics of roomdb. | unknown | |

d9437 | train | You may start with the Unix "High-level process and redirection management" functions, e.g., create_process prog args new_stdin new_stdout new_stderr is a generic function that will create a process that runs a program, and it allows you to redirect the channels. The created process will run asynchronously, so you can either peek it with waitpid's WNOHANG flag, or just block until it ends (probably the latter shouldn't work for you).
Probably, the following interface should suffice your needs:
module Monitor : sig
val start : string -> t
val terminate : t -> unit
val on_finish : t -> (int -> unit) -> unit
...
end
or you can just simplify it to
val monitor : string -> (int -> 'a) -> 'a
if you don't want to have to manage monitor instances.
Alternatively, you can take a look at the Lwt high-level process management library. It might save you quite a few keystrokes. There is also an alternative async unix library from Janestreet, that you may try. | unknown | |
d9438 | train | I think the issue is that you are trying to use the entire text as the key to the dictionary. So, if the text "A" is entered into the text input then it works as "A" is a key in my_dictionary. If the text "AS" is entered into the text box, this will fail as there is no key "AS" in my_dictionary.
What you will want to do, therefore, is loop over each of the characters in the entered string and add the Morse value of that letter to your definition string. You will also want to make sure that the letter is uppercase (unless it is guaranteed that the input will be upper case). This is done using the string .upper() method in the following example. Something like the following should do what you want.
definition = str() # Create a blank string to add the Morse code to
# Go through each letter and add the Morse definition of the letter to definition
for letter in entered_text:
definition += my_dict[letter.upper()] # The upper makes sure the letter is a capital so that there will be a match in my_dict | unknown | |

A: To answer your comment to my Comment. Since FindControl takes a string as an input you would just create the string with the component name you are looking for. Be aware that you have to use the FindControl Method of the container that your labels are in.
From Link(emphasis mine):
Use FindControl to access a control from a function in a code-behind page, to access a control that is inside another container, or in other circumstances where the target control is not directly accessible to the caller. This method will find a control only if the control is directly contained by the specified container; that is, the method does not search throughout a hierarchy of controls within controls. For information about how to find a control when you do not know its immediate container, see How to: Access Server Controls by ID.
so something like this should work for you.

d9440 | train | I just do:
val bytes = listOf(0xa1, 0x2e, 0x38, 0xd4, 0x89, 0xc3)
.map { it.toByte() }
.toByteArray()
A: as an option you can create simple function
fun byteArrayOfInts(vararg ints: Int) = ByteArray(ints.size) { pos -> ints[pos].toByte() }
and use it
val arr = byteArrayOfInts(0xA1, 0x2E, 0x38, 0xD4, 0x89, 0xC3)
A: If all your bytes were less than or equal to 0x7F, you could put them directly:
byteArrayOf(0x2E, 0x38)
If you need to use bytes greater than 0x7F, you can use unsigned literals to make a UByteArray and then convert it back into a ByteArray:
ubyteArrayOf(0xA1U, 0x2EU, 0x38U, 0xD4U, 0x89U, 0xC3U).toByteArray()
I think it's a lot better than appending .toByte() at every element, and there's no need to define a custom function as well.
However, Kotlin's unsigned types are an experimental feature, so you may have some trouble with warnings.
A: The issue is that bytes in Kotlin are signed, which means they can only represent values in the [-128, 127] range. You can test this by creating a ByteArray like this:
val limits = byteArrayOf(-0x81, -0x80, -0x79, 0x00, 0x79, 0x80)
Only the first and last values will produce an error, because they are out of the valid range by 1.
This is the same behaviour as in Java, and the solution will probably be to use a larger number type if your values don't fit in a Byte (or offset them by 128, etc).
Side note: if you print the contents of the array you've created with toInt calls, you'll see that your values larger than 127 have flipped over to negative numbers:
val bytes = byteArrayOf(0xA1.toByte(), 0x2E.toByte(), 0x38.toByte(), 0xD4.toByte(), 0x89.toByte(), 0xC3.toByte())
println(bytes.joinToString()) // -95, 46, 56, -44, -119, -61 | unknown | |

If you don't have id for your table and you have only one table on the page, do this:

Exec(ExpandConstant('{dotnet40}\InstallUtil.exe'), ServiceLocation, '', SW_HIDE, ewWaitUntilTerminated, ResultCode);
Apparently, Inno setup has the following constants for referencing the .NET folder on your system:
*
*{dotnet11}
*{dotnet20}
*{dotnet2032}
*{dotnet2064}
*{dotnet40}
*{dotnet4032}
*{dotnet4064}
More information available here.
A: You can use
Exec(
ExpandConstant('{sys}\sc.exe'),
ExpandConstant('create "MyService" binPath= {app}\MyService.exe start= auto DisplayName= "My Service" obj= LocalSystem'),
'',
SW_HIDE,
ewWaitUntilTerminated,
ResultCode
)
to create a service. See "sc.exe" on how to start, stop, check service status, delete service, etc.
A: You don't need installutil.exe and probably you don't even have rights to redistribute it.
Here is the way I'm doing it in my application:
using System;
using System.Collections.Generic;
using System.Configuration.Install;
using System.IO;
using System.Linq;
using System.Reflection;
using System.ServiceProcess;
using System.Text;
static void Main(string[] args)
{
if (System.Environment.UserInteractive)
{
string parameter = string.Concat(args);
switch (parameter)
{
case "--install":
ManagedInstallerClass.InstallHelper(new string[] { Assembly.GetExecutingAssembly().Location });
break;
case "--uninstall":
ManagedInstallerClass.InstallHelper(new string[] { "/u", Assembly.GetExecutingAssembly().Location });
break;
}
}
else
{
ServiceBase.Run(new WindowsService());
}
}
Basically you can have your service to install/uninstall on its own by using ManagedInstallerClass as shown in my example.
Then it's just matter of adding into your InnoSetup script something like this:
[Run]
Filename: "{app}\MYSERVICE.EXE"; Parameters: "--install"
[UninstallRun]
Filename: "{app}\MYSERVICE.EXE"; Parameters: "--uninstall"
A: If you want to avoid reboots when the user upgrades then you need to stop the service before copying the exe and start again after.
There are some script functions to do this at Service - Functions to Start, Stop, Install, Remove a Service
A: have a look at topshelf
http://topshelf-project.com/
*
*it lets you develop your service as a console application
*adds a start/stop service as an API to your service...

d9456 | train | What you can do for solving the vertical constraint issue is to give Equal constraints to your button1 and button2 and give a fixed vertical constraint to the something view and from your second button to the bottom of the superview.
So this way you won`t need to give a fixed height to any of them and the distance between them and other elements (something and bottom of superview) will be standard.
I hope this helps!
A: Ok, I think I made it.
Here is what I did :
*
*I set all my constraints in the storyboard, with the Retina 4" form-factor.
*Constraints for the something view : fixed height & width, fixed top space and leading space. This view is absolutely fixed.
*Constraints for button 1 : fixed vertical space to something view, fixed leading space, fixed width. 2 height constraints : 30 <= height <= 50.
*Constraints for button 2 : fixed vertical space to button 1, fixed leading space, fixed width. Also 2 height constraints : 30 <= height <= 50. And fixed bottom space to bottom layout.
All constraints have a maximum priority of 1000, except the last one (fixed bottom space to bottom layout), which is set at 900 !
That way, the buttons keep a height >=30 and move up, but get shrinked vertically because the other constraints are more important.
Thanks a lot to @VasiliyDeych and @P.Sami for their advice. It helped a lot.
A: You're going to need to show us how your constraints are set up.
Constraints are a set of rules that the views must follow. If there is no rule saying the button must shrink with the parent view, it will not happen.
Based on your example, if I understood it correctly, you would want a set of constraints like this (defined in VFL for ease):
[yourParentView addVisualConstraints:@"V:|[something(100@75)]-(10@100)-[button1(<=50,>=30@100)]-(10@100)-[button2(button1@100)]-(>=300@50)-|"
forViews:NSDictionaryOfVariableBindings(something,button1,button2)];
All constraints here are vertical (V:), the numbers in parentheses represent a number of points, followed by @ and the desired priority of maintaining that number of points. The | symbols represent the top and bottom edges of the superview. So ]-(>=300@50)-| is saying, I'd like to keep 300 or more pixels between button2 and the bottom of the superview, but I care about it with a priority of 50. button1(<=50,>=30@100) means I really care that this button is between 30 and 50 pixels in height, with a priority of 100. button2(button1) means I want button2 to be the same height as button1. I also really care about keeping that 10-point distance between my elements. And I somewhat care that something (which is flush to the superview's top edge, hence |[) is going to stay at 100 points tall.
Does this not work for what you are intending to do? | unknown | |
d9457 | train | It might be easier to use the OpenDirectory for the windows boxes but thats not the question.
You can use OpenLDAP as backend for your Macs. But the OpenLDAP has to implement the schema of the OpenDirectory (which in itself uses OpenLDAP as backend). Those schema-files are lokated in different places depending on the MacOSVersion you are using.
you have to place those files inside the OpenLDAPs schema folder and restart the ldap. After that you can extend the users to make use of that Information. But you will have to adapt the mapping of Information on the Mac-clients so that all relevant information from the LDAP ends up in the right places. Not an easy task. I'd think twice wheter it makes sense for a handfull or two of macBoxes. We've implemented for 150 Macs and it was a pain to get everything right.
And AFAIK there is no easy way of bringing an OpenLDAP and an OpenDirectoy in synch eith one another due to the schema extension apple used.
Depending on the frontend you use you might be able to implement a mechanism that adds a user to two LDAPs when the are created but what about changing passwords? Or changing a users name? you will have to do a lot of manual adaptions to make that possible.
So In my opinion not an easy task especially when you have to catch up on some LDAP stuff and the LDAP documentation of Apple is rather sparse...
A: Your question title says "Import OpenLDAP directory into OSX Open Directory".
Which you certainly can. LDAP is a wire protocol.
Check out PORTABLE HOME DIRECTORIES WITH OPENLDAP
You then ask "is it possible to be able to sync Open Directory with the OpenLDAP server".
Yes, there are many IDM products out there that will allow sync two LDAP directories. NetIQ IDM, http://forgerock.com/, and many others. But, probably more than you want to deal with. (I think they are best for 1000+ Users)
A: Use below listed function and export that schema to LDIF format.
ldapmodify
If possible then use ldap admin tool
phpldapadmin,ldap admin etc
Export whole shema or branch in ldif and .xml(dsml) type.
Then Inport it to desired directory server by using admin tool else commandline function
ldapadd | unknown | |

If you only need to determine drive speed and not really interested in learning how to flush I/O buffers from .NET, you may just use DiskSpd utility from http://research.microsoft.com/barc/Sequential_IO/. It has random/sequential modes with and without buffer flushing.
The page also has some I/O related research reports you might find useful.
A: const int FILE_FLAG_NO_BUFFERING = 0x20000000;
return new FileStream(path, FileMode.Open, FileAccess.Read, FileShare.Read,64 * 1024,
(FileOptions)FILE_FLAG_NO_BUFFERING | FileOptions.Asynchronous
& FileOptions.SequentialScan);
A: Constantin: Thanks! That link has a command-line EXE which does the testing I was looking for.
I also found a link off that page to a more interesting article (in Word and PDF) on this page: Sequential File Programming Patterns and Performance with .NET
In this article, it talks about Un-buffered File Performance (iow, no read/write caching -- just raw disk performance.)
Quoted directly from the article:
There is no simple way to disable
FileStream buffering in the V2 .NET
framework. One must invoke the Windows
file system directly to obtain an
un-buffered file handle and then
‘wrap’ the result in a FileStream as
follows in C#:
[DllImport("kernel32", SetLastError=true)]
static extern unsafe SafeFileHandle CreateFile(
string FileName, // file name
uint DesiredAccess, // access mode
uint ShareMode, // share mode
IntPtr SecurityAttributes, // Security Attr
uint CreationDisposition, // how to create
uint FlagsAndAttributes, // file attributes
SafeFileHandle hTemplate // template file
);
SafeFileHandle handle = CreateFile(FileName,
FileAccess.Read,
FileShare.None,
IntPtr.Zero,
FileMode.Open,
FILE_FLAG_NO_BUFFERING,
null);
FileStream stream = new FileStream(handle,
FileAccess.Read,
true,
4096);
Calling CreateFile() with the
FILE_FLAG_NO_BUFFERING flag tells the
file system to bypass all software
memory caching for the file. The
‘true’ value passed as the third
argument to the FileStream constructor
indicates that the stream should take
ownership of the file handle, meaning
that the file handle will
automatically be closed when the
stream is closed. After this
hocus-pocus, the un-buffered file
stream is read and written in the same
way as any other.
A: Response of Fix was almost right and better than PInvoke.
But it has bugs and doesn't works...
To open up File w/o caching one needs to do following:
const FileOptions FileFlagNoBuffering = (FileOptions)0x20000000;
FileStream file = new FileStream(fileName, fileMode, fileAccess, fileShare, blockSize,
FileFlagNoBuffering | FileOptions.WriteThrough | fileOptions);
Few rules:
*
*blockSize must be hard drive cluster size aligned (4096 most of the time)
*file position change must be cluster size aligned
*you can't read/write less than blockSize or block not aligned to it's size
And don't forget - there is also HDD Cache (which slower and smaller than OS cache) which you can't turn off by that (but sometimes FileOptions.WriteThrough helps for not caching writes). With those options you have no reason for flushing, but make sure you've properly tested that this approach won't slow things down in case your implementation of cache is slower.
A: I found this article and it seems that this is a complicated program because you also have to flush other caches. | unknown | |
d9459 | train | I don't have a direct answer to your question, other than to ask you why are you trying to do it this way. The best practice is to move your static files to S3 or ideally, CloudFront (or another non-AWS solution).
Use django-storages-redux (https://github.com/jschneier/django-storages) to use static files from S3 for production. Google 'django s3 static' and you will find several blogs explaining the process. The documentation is here.
A: collectstatic command would have collected all your static file to STATIC_ROOT which you had set as "/PATH/TO/myapp/static/static-only.
So I suspect that you pointed your static files to the wrong directory in the config file.
Try "/static/": "myapp/static/static-only" | unknown | |
d9460 | train | You want to parse them into some kind of time-duration object.
A simple way, looking at that data, would be to check wheter " or / occurs, if " parse as seconds, / parse as fraction of seconds. I don't really understand what else you could mean. For an example you'd need to specify a language--also, there might be a parser out there already.
A: Shutter speed is encoded in the EXIF metadata as an SRATIONAL, 32-bits for the numerator and 32-bits for the denominator. Sample code that retrieves it, using System.Drawing:
var bmp = new Bitmap(@"c:\temp\canon-ixus.jpg");
if (bmp.PropertyIdList.Contains(37377)) {
byte[] spencoded = bmp.GetPropertyItem(37377).Value;
int numerator = BitConverter.ToInt32(spencoded, 0);
int denominator = BitConverter.ToInt32(spencoded, 4);
Console.WriteLine("Shutter speed = {0}/{1}", numerator, denominator);
}
Output: Shutter speed = 553859/65536, sample image retrieved here.
A: It seems there are three types of string you will encounter:
*
*String with double quotes " for seconds
*String with leading 1/
*String with no special characters
I propose you simply test for these conditions and parse the value accordingly using floats:
string[] InputSpeeds = new[] { "279\"", "30\"", "5\"", "3.2\"", "1.6\"", "1.3\"", "1\"", "1/1.3", "1/1.6", "1/2", "1/2.5", "1/3", "1/4", "1/5", "1/8", "1/13", "1/8000", "1/16000" };
List<float> OutputSpeeds = new List<float>();
foreach (string s in InputSpeeds)
{
float ConvertedSpeed;
if (s.Contains("\""))
{
float.TryParse(s.Replace("\"", String.Empty), out ConvertedSpeed);
OutputSpeeds.Add(ConvertedSpeed);
}
else if (s.Contains("1/"))
{
float.TryParse(s.Remove(0, 2), out ConvertedSpeed);
if (ConvertedSpeed == 0)
{
OutputSpeeds.Add(0F);
}
else
{
OutputSpeeds.Add(1 / ConvertedSpeed);
}
}
else
{
float.TryParse(s, out ConvertedSpeed);
OutputSpeeds.Add(ConvertedSpeed);
}
}
If you want TimeSpans simply change the List<float> to List<TimeSpan> and instead of adding the float to the list, use TimeSpan.FromSeconds(ConvertedSpeed); | unknown | |

d9462 | train | Where $1 is id and passed via params.
SQL does not allow to parametrize object names like column names. In most cases you get a syntax error right away if you try this kind of nonsense. Unfortunately, the ORDER BY clause does not necessarily expect a column name, but allows expressions including a constant (typed) value (which can be parameterized).
If you pass 'id' to this prepared query, this is what happens:
SELECT * FROM transactions ORDER BY 'id'::text DESC LIMIT 100;
ORDER BY <constant value> is just noise and has no effect on the result.
Turn on the server logs to check what the database actually receives. To parameterize column names like you seem to have in mind, you need dynamic SQL, i.e. first concatenate the query string and then execute it. | unknown | |
d9463 | train | Certainly.
The company I work for has done this in the past.
If you know you might want to do this in the future, in your first version store a flag to NSUserDefaults indicating that the user has had the paid version. Then, on your In-App version check this flag and provide the content immediately.
If you already have a version released, you may have to look for something that you are already storing, e.g. the user has a highscore greater than zero to indicate that the user has already purchased the app. (There will be a small number of users that may have downloaded the app but not opened it and these users may be charged twice).

d9465 | train | First there should be no declaration of unsigned visible due to conflicts between packages std_logic_arith and numeric_std. Use one or the other (numeric_std is part of the VHDL standard).
Second the element type of VTIN is std_logic or std_ulogic depending on the VHDL revision which isn't compatible with the array type/subtype std_logic_vector. That means type conversion isn't legal.
Next a concurrent signal assignment is elaborated into a process which implies a driver for the longest static prefix (here cont). Having VTIN'LENGTH processes with generate 'X's, the values will be resolved, the driver outputs are shorted.
Instead of a generate statement use a process with a variable used to count '1's in a sequential loop statement with a for iteration scheme. The variable is used because the value of signal cont isn't updated until the process suspends. You assign the variable value to cont after the loop statement. After the process suspends, the value of cont will be available to use in the assignment to VTOUT. std_logic_arith can added a std_logic value to a std_logic_vector as can numeric_std in -2008 (otherwise unsigned(""& VTIN(i)) converts std_logic to unsigned. You could also implement a subprogram.
library IEEE;
use IEEE.STD_LOGIC_1164.ALL;
-- use ieee.std_logic_arith.all;
use IEEE.NUMERIC_STD.ALL;
entity proj2_1 is
GENERIC (N: INTEGER := 8); -- SIZE OF THE VECTOR
Port ( VTIN : in STD_LOGIC_VECTOR (N-1 downto 0);
VTOUT : out STD_LOGIC_VECTOR (N-1 downto 0);
cont: buffer unsigned (N-1 downto 0) );
end entity proj2_1;
architecture behavioral of proj2_1 is
begin
-- gen: FOR i IN VTIN' RANGE GENERATE
-- BEGIN
-- cont <= cont + ( unsigned (VTIN(i)));
-- END GENERATE;
SEQUENTIAL_LOOP_NOT_GENERATE_STATEMENT:
process (VTIN)
variable ones: unsigned(VTOUT'RANGE);
begin
ones := (others => '0'); -- zero
for i in VTIN'RANGE loop
ones := ones + unsigned'("" & VTIN(i));
end loop;
VTOUT <= std_logic_vector (cont + ones);
end process;
end architecture behavioral;
A generate statement is a concurrent statement which elaborates to a block statement for every value of the generate parameter containing the concurrent statement which has a process statement equivalent. A process statement has a driver for each signal assigned in it's sequence of statements. One driver versus lots of drivers.
With package numeric std you could also declare the variable (here ones) as an integer (natural). numeric_std supports the addition of natural range integers to unsigned values.
Notice there's nothing that defines an initial value for port cont which has a mode of buffer, essentially an output that be read internally. The default initial value will be (others => 'U')from the left most value of the enumerated type std_ulogic. Either the original intent is wrong (count all the 1's from a std_logic_vector" or more likely you actually one the population count of '1's in VTIN.
The latter requires a change:
architecture behavioral of proj2_1 is
begin
SEQUENTIAL_LOOP_NOT_GENERATE_STATEMENT:
process (VTIN)
variable ones: unsigned(VTOUT'RANGE);
begin
ones := (others => '0'); -- zero
for i in VTIN'RANGE loop
ones := ones + unsigned'("" & VTIN(i));
end loop;
-- VTOUT <= std_logic_vector (cont + ones);
VTOUT <= std_logic_vector (ones);
cont <= ones;
end process;
end architecture behavioral;
that doesn't reflect the original code but doesn't accumulate across new values of VTIN and is synthesis eligible.
The integer variable version of the population count of '1's could look like
architecture integer_variable of proj2_1 is
begin
SEQUENTIAL_LOOP_NOT_GENERATE_STATEMENT:
process (VTIN)
variable ones: natural;
begin
ones := 0;
for i in VTIN'RANGE loop
if TO_BIT(VTIN(i)) = '1' then
ones := ones + 1;
end if;
end loop;
VTOUT <= std_logic_vector (to_unsigned(ones, VTOUT'length));
cont <= to_unsigned(ones, VTOUT'length); -- and both outputs don't make sense
end process;
end architecture integer_variable;
where adding an integer value doesn't propagate meta values from VTIN during addition. | unknown | |

d9468 | train | I am assuming that each foid represents a gallery:
SELECT foid, uid, date,
(CASE WHEN pic1 IS NULL THEN 0 ELSE 1 END +
CASE WHEN pic2 IS NULL THEN 0 ELSE 1 END +
CASE WHEN pic3 IS NULL THEN 0 ELSE 1 END
) AS pic_count
FROM foto
WHERE uid = $id
ORDER BY foid DESC
Incidentally, this isn't a particularly sensible way to structure your schema. You really should split the pics out as a separate table:
foto:
foid | uid | date
-----------------------
104 | 5 | 2010-01-01
105 | 14 | 2009-04-08
106 | 48 | 2010-08-09
pic:
foid | pic
------------
104 | 1.jpg
104 | 2.jpg
104 | 3.jpg
105 | 8.jpg
106 | x.jpg
106 | y.jpg
Now, galleries can have more than three pics and querying is simpler:
SELECT foid, uid, date, COUNT(*)
FROM foto
JOIN pic USING (foid)
WHERE uid = $id
ORDER BY foid DESC
GROUP BY foid, uid, date
EDIT: You can split an existing database thus (just guessing at stuff like column types):
CREATE TABLE picture (foid INT, pic VARCHAR(255));
INSERT INTO picture (foid, pic)
SELECT foid, pic1 as pic FROM foto WHERE pic IS NOT NULL
UNION
SELECT foid, pic2 as pic FROM foto WHERE pic IS NOT NULL
UNION
SELECT foid, pic3 as pic FROM foto WHERE pic IS NOT NULL
;
ALTER TABLE foto
DROP COLUMN pic1,
DROP COLUMN pic2,
DROP COLUMN pic3
;
Obviously, one should exercise considerable care when dropping columns, and make a backup before you start! | unknown | |
d9469 | train | It seems for me as a bug in Internet Explorer. In the official Document Object Model HTML standard I could found the following description about the namedItem method intensively used by jqGrid:
This method retrieves a Node using a name. With [HTML 4.01] documents,
it first searches for a Node with a matching id attribute. If it
doesn't find one, it then searches for a Node with a matching name
attribute, but only on those elements that are allowed a name
attribute. With [XHTML 1.0] documents, this method only searches for
Nodes with a matching id attribute. This method is case insensitive in
HTML documents and case sensitive in XHTML documents.
So the namedItem method should works case sensitive in XHTML documents. On the other side like you can test in the demo, which use only pure DOM without jQuery or jqGrid, the method work case insensitive in Internet Explorer.
The HTML code of the demo is following:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

var mytable = document.getElementById("t"),
tr1 = mytable.rows.namedItem("x"),
tr2 = mytable.rows.namedItem("X"),
tr3 = document.getElementById("x"),
tr4 = document.getElementById("X");
alert("getElementById works " + (tr3.id === tr4.id ? "case insensitive (BUG!!!)": "case sensitive") +
"\nnamedItem works " + (tr1.id === tr2.id ? "case insensitive (BUG!!!)": "case sensitive"));
</script>
</body>
</html>
The Internet Explorer shows that namedItem("X") returns the row with the id="x" instead of the row having id="X". The same bug not exist in all other (non-Microsoft) web browsers where I tested it.
I can't suggest you currently no workaround. You should just organize you program so that you will not use case sensitive ids inside of tables (and with jqGrid).
UPDATED: Just a little more additional information.
I made an official support request to Microsoft about the described subject. Microsoft confirmed that it was a bug in Internet Explorer, but the bug will be not fixed in the current Internet Explorer versions, but it will be probably fixed in IE10. As a workaround :-) it was suggested not to use ids which distinguish only in case. So just not use the ids which can reproduce the bug. So we have at the end results as I supposed before in my previously comments.
Nevertheless, because the response confirmed that it was a bug, the request to Microsoft was for free for me (:-)). | unknown | |
d9470 | train | You can use this plugin to get a list of all fonts of your device:
cordova-plugin-fonts
Then you can show to the user a list, let them select one and after that you change the css of your site by javascript.
I'm not sure, but it could be, that you have to rerender the page after changing the font.
A: Seems something you could easily do with javascript/css.
Just ship your fonts in the app, to make sure they are available on any platform, and add a listener to your select which changes a css class to the body.
This is the html code if you are using jQuery or Zepto syntax.
<select name="changeFont" id="font-selector" onchange='$("body").attr("data-font", $("#font-selector").val())'>
<option value="default">Default</option>
<option value="arial">Arial</option>
<option value="comic-sans">Comic Sans</option>
</select>
then in css
.mytext {
font-family: helvetica, sans-serif;
}
[data-font=arial] .mytext {
font-family: arial, sans-serif;
}
[data-font=comic-sans] .mytext {
font-family: "comic sans", sans-serif;
}
For this to work, just make sure that you have correctly added your fonts. To make this right you could use FontSquirrel webfont generator to convert any font to a web font and generate the needed css for you.
I should add that I did not test this, so let me know if you find it's not working.
Or, if your app is designed to work only when the user has internet connection then there's an even quicker way to add a lot of fonts. There's a jQuery plugin that will do exactly that. | unknown | |

d9478 | train | It can be easily done using jQuery. Have two divs, one at the top and another at the bottom. Now, when you have a large screen size, give the html of the navbar to the above div and to the bottom one if the screen size is small.

if (screenSize > 1280px) $(#topnav).html('Your navbar HTML here');
else $(#bottomnav).html('Your navbar HTML here');

So you can replace the nulls present in your data with pd.NaT instead of np.nan
you can use below thing as well...
df['date'].replace(np.NaN, pd.NaT)
or
df['date'].fillna(pd.NaT)
Hope it is helpful for you :) | unknown | |

d9482 | train | You can do black box testing by verifying the exit code and the output of the program to the standard output stream and standard error stream.
You can do white box testing by keeping a reference to your application and asserting on the state of your application after giving it various command line inputs.
For example:
MyApp app = new MyApp();
StringWriter sw = new StringWriter();
CommandLine cmd = new CommandLine(app);
cmd.setOut(new PrintWriter(sw));
// black box testing
int exitCode = cmd.execute("-x", "-y=123");
assertEquals(0, exitCode);
assertEquals("Your output is abc...", sw.toString());
// white box testing
assertEquals("expectedValue1", app.getState1());
assertEquals("expectedValue2", app.getState2());
Update: the picocli user manual now has a separate section about Testing. | unknown | |
d9483 | train | Ok, nobody answered it, and I figured it out. There are two "practical" solutions, first one is using the Quaternions. You can define a 3d rectangle as a view and then rotate it using quaternions. After that you can sweep on the resulting rectangle, and use the reverse transforms to get the map coordinates. The other solution, which seems faster to me, is using Euler's rotation matrices. Just pay attention to use ArcTan2 instead of ArcTan function, because you need 2*PI coverage. That's all I wanted! | unknown | |
d9484 | train | You can use the Firewall > Traffic Shaper > Wizards option to do this. I don't recommend dedicating even bandwidth to each user since they don't use the connection at the same time constantly wherein if a user is idle then you are wasting bandwidth at their idle time. Managing priorities on protocols and applications while penalizing abusers is enough. | unknown | |
d9485 | train | Yes, this is normal. If you want to insert with a specific ID number you have to specify that number on your insert statement.
The idea of auto increment is for the value to continually increase.
A: This is normal, though for some database engines you might receive 2, but usually it will be 6. In MSSQL it is possible to specify a value for an autoinc field with particular setting. Not sure what it is in mysql.
A: That's the expected behavior. Autoincrement primary keys are designed to be unique and continually increasing - so they are not assigned again.
If you TRUNCATE a table the autoincrement value is being reset while it stays as it is if you delete all rows with an DELETE query - that's a subtle but sometimes important difference.
As webdestroya suggested, the only possibility to reuse old and deleted autoincrement values is to set them specifically on the INSERT statement. | unknown | |
d9486 | train | Nice way to do this is to compare URL Host which can be done using the following approach
func webView(_ webView: WKWebView, decidePolicyFor navigationAction: WKNavigationAction, decisionHandler: @escaping (WKNavigationActionPolicy) -> Void) {
let exceptedHosts: [String] = [
"facebook.com",
"m.facebook.com"
]
if let host = navigationAction.request.url?.host {
if exceptedHosts.contains(host) {
decisionHandler(.cancel)
return
}
}
decisionHandler(.allow)
}
This will prevent any url with facebook.com or m.facebook.com from being opened, add any hosts to the array to except them from being opened.

d9487 | train | Please post your layout XML R.layout.fragment_sixth. Probably you're referring to a wrong id, which causes de NullPointerException.
To get each "Breakfast", "Lunch" and "Dinner" separately, you can simply iterate through the last three <div> tags inside the HTML element with id MainContent_divDailySpecials (I did find that id looking at the website DOM structure through Chrome Developer Tools inspector).
So, as a start, simply grab that element with
Document document = Jsoup.connect(url).get();
Element parentDiv = document.getElementById("MainContent_divDailySpecials");
and from there on you can iterate backwards to get the last three children of that div. (Please keep in mind that if, in any point in time, the structure of that page changes your code will break).
A: Looking at the error log you attached ..
java.lang.NullPointerException: Attempt to invoke virtual method
'void android.widget.TextView.setText(java.lang.CharSequence)' on a null object reference
at com.lamdevs.tritonbites.fragments.SixthFragment$JSOUP.onPostExecute(SixthFragment.java:82)
It talks about a NullPointerException on a TextView in SixthFragment Line 82 i.e. textview.setText(MENU);
The textview is initialized (textview = (TextView) rootView.findViewById(R.id.textView10);) which looks okay.
So, make sure you have a TextView with id textView10 in your layout fragment_sixth. | unknown | |

d9489 | train | I found the problem...
Excel exported the text with Windows encoding, so it looked correct even in TextMate on my mac. When I reopen with UTF8 encoding the problem was visible in the translations file.
To resolve I used EditPadPro on a PC to convert to UTF8.
Phew.
A: Maybe you could try adding this inside your <head> tag?
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
A: I use Coda but I think textmate has to offer some option like Text->Encoding->Unicode UTF-8, activate it and then your file will be encoded properly and then save it.
Anyway if you are going to put some forms and you are not sure the people is using the correct encoding mode you'll have the same problem.
Use something like this:
<?php
$not_utf8 = "An invalid string"; //Put here the bad text for testing
$not_utf8 = mb_convert_encoding($not_utf8, 'UTF-8', mb_detect_encoding($not_utf8));
echo htmlspecialchars($not_utf8, ENT_QUOTES, 'UTF-8'); //The output should be ok, see the source code generated and search for the correct html entities for these special chars
?>
Hope this help you!
Luis.
A:
The page encoding is UTF8, and I've added:
Probably not. Make sure that the php file is actually saved with utf-8 encoding. | unknown | |

d9491 | train | A large number of classes is not going to affect the performance of the application. Some good practices in Android, however, include placing values like integers, item IDs, and request codes into a Resources xml file.
You will also see a lot of Callback classes as inner interfaces of the Object they relate to:
public class MyObject
{
private Callback callback;
private Object returnObject;
public void setCallback(Callback callback)
{
this.callback = callback;
}
public void doSomething()
{
//do something - could be an anync task or other that assigns returnObject
callback.invoke(returnObject);
}
public interface Callback
{
public void invoke(Object obj);
}
}
Then you can use this as follows:
MyObject obj = new MyObject();
obj.setCallback(new MyObject.Callback() {
@Override
public void invoke(Object obj) {
Log.i("Callback", obj.toString());
}
});
obj.doSomething(); | unknown | |
d9492 | train | I would find the bounding box of hole and then inspect the sides. find the one that is not linear but curved instead and set that as circle border. Then fit circle to that side only. For more info see:
*
*fitting ellipses
*Finding holes in 2d point sets
A: If you can scale the coordinates in order to draw the point into an image, here is a solution:
*
*Draw the points into an image
*Compute the distance map using all the points as a source point.
*Then, each pixel will contain the distance to the closets point. So the pixel with the highest value will be the center of the largest circle, and the pixel value will be the circle radius.
*Find the closest points to the circle center.
*Find the circle passing by all theses points (Hough?). The solution might not be unique. | unknown | |
d9493 | train | The T in WrapperImpl<T> can be constrained on any subtype of Base, not just Base itself. Functionality in put should be able to safely access v.derived_property if T : Base is simply changed to a T : Derived.

d9494 | train | I believe the only thing you can do in this case is to use the users/lookup or users/show endpoints to check whether those user IDs return a Not Found error (or similar) in order to filter them out from your result set.

d9495 | train | There isn't really, they're not 100% correct/valid usage in HTML4 of course....but they don't cause problems either, so they're still a great way to solve the "I need an attribute for this" problem.
If it helps, I've used these while supporting IE6 and have had zero issues thus far, and I can't recall a single SO question reporting any either.
A: Internet Explorer and Microsoft has added several custom attributes that are not valid HTML4. Browsers don't check the element attributes against a specification, you can name an attribute roryscoolinfo="hello" if you like (though you shouldn't).
The Dojo Toolkit adds its custom dojo* attributes.
It's fine to use data- today, with a HTML5 doctype. | unknown | |
d9496 | train | this might help
$obj = new SimpleXMLElement($xml);
$rtn = array();
$cnt = 0;
foreach($obj->xpath('///OSes/*/*') as $rec)
{
foreach ($rec as $rec_obj)
{
if (!isset($rtn[$cnt]))

$rtn[$cnt] = array();
}
foreach ($rec_obj as $name=>$val)
{
$rtn[$cnt][(string)$name] = (string)$val;

++$cnt;
}
}
A: By modifying the xpath as others suggested as well, I came to this conclusion. It works with one helper function to re-format each xpath result node and uses array_reduce to iterate over the result. It then returns the converted result (Demo):
$xml = new SimpleXMLElement($xmlstr);
$elements = array_reduce(
$xml->xpath('//OSes/*/*'),
function($v, $w) {
$w = array_values((array) $w); // convert result to array
foreach($w as &$d) $d = (array) $d; // convert inner elements to array
return array_merge($v, $w); // merge with existing
},
array() // empty elements at start
);
Output:
Array
(
[0] => Array
(
[id] => centos5-32
[name] => CentOS 5 - 32 bit
[version] => 5
[architecture] => 32
[os] => centos
)

[name] => CentOS 5 - 64 bit

(
[id] => ubuntu10-64
[name] => Ubuntu 10 - 64 bit
[version] => 10
[architecture] => 64
[os] => ubuntu
)
)
I also opted for converting the original xpath result into an array of two levels, each time within the current level a key already exists, move the current entry to a new entry (Demo):
try
{
$xml = new SimpleXMLElement($xmlstr);
$elements = array();
$curr = NULL;
foreach($xml->xpath('//id | //name | //version | //architecture | //os') as $record)
{
$key = $record->getName();
$value = (string) $record;
if (!$curr || array_key_exists($key, $curr)) {
unset($curr);
$curr = array();
$elements[] = &$curr;
}
$curr[$key] = $value;
}
unset($curr);
}
catch(Exception $e)
{
echo $e->getMessage();
}
Result is like this then:

d9498 | train | I would say the best way to do it would be to cut your dependencies so that they can reference as external jars. This way when you make potentially breaking changes you don't necessarily have to fix the affected areas straight away. Since they depend on a previously built jar it allows you to properly isolate your coding. If you use something like Maven to manage your dependencies you will also benefit from the ability to more easily keep track of the different versions of your jars.
A: If the subprojects are sufficiently autonomous, I would advise setting them up as separate maven projects with separate VCS repos.
This will give you the modularity you need paired with a working dependency management. | unknown | |
