asp.net - Store/assign roles of authenticated users -

I am upgrading a site to use MVC and I am looking for the best way to set up authentication. .

At this point, I have to log in to Active Directory logging: Validating the username and password, and then setting up Auth cookie.

How do I store the user's role at the time of log -No, to see my controllers for those roles, as the user navigates through the site?

  [Author (roles = "admin")]  

I have no problem getting a list of roles from Active Directory I do not know That's where they keep them so that the controller can see them.

When you authenticate your user, you generate a new GenericPrincipal example. The constructor takes an array of strings that have roles for the user. Now set HttpContext.Current.User equal to the Genetic Principle and write auth cookie, and should do so.

How do I manage my ideas/personal projects to completion? -

I suspect that many developers are in the same boat. There are so many gestures in the world to scratch, Simple, they can be "one weekend" And yet they are never, we have handcuffs like jobs, families, and other hobbies ... it can be hopeless!

I have a long list of projects that I would like to annotate and classify in a wiki, but I have not spent much time with them. In the initial steps of the scheme, the colleges and colleges that meet me are very excited. But when the time comes to work on real time, the excuses start flowing and the wave of enthusiasm begins.

What do you do to make your thoughts interesting? If there are many, there are different projects to choose from, how do you choose?

(I know there is a question with a similar title already, but it was more about code management.)

The most important thing is to get started.

It seems that you have some options, do such a thing to do such a thing that you know that you will not try to make a decision again immediately after starting

< Ul>

Do the simplest work to get the 0.1 version (looks like it's attractive, leave the integration for Twitter later).

Always leave at a point where the next thing is clear;

Do not try to know too many new technologies in a project, they will slow you down.

"Explore social make-up to talk about friends / press" pressurize "to complete / release the application etc. Better yet, choose an app that will be useful for anyone at work ( HR?) There is nothing around the user waiting to inspire you.

sqlite3 - SQLITE group by -

I use the group in SQLite from time interval in SQLite. The first day is the group and the second group has an hour:

  select striptime ('% Y-% m-% dT% 00: 00: 00.000', date_time), line, calculation (( Count by 'Sprime' ('% Y-% m-% dT% H: 00: 00.000', date_time) from the line, entry group '% Y-% m-% dT% H: 00: 00.000', date_time) () ())  

How do I group with a 10 minute interval

  select ... strftime ('% y% m% d% H0', date_time) from entry group + stroke ('% M', date_time) / 10;  

c# - Dynamic method dispatch based on value of variable -

Long switch statements are often frowned upon using solution polymorphism However, what I'm switching over is one Not a type of code? What I would like to do is replace the switch statement with something like this ... Public Zero Handelring (String S = "Hello") {...} Public Zero Handstring (String S = "Bye") {...} ... Handlists ("Hello"); // The first method is being called

This will replace the following ...

  string s = "hello"; Switch (s) {case "hello": ... break; The case "goodbye": ... break; Default; break; }  

Any ideas? In theory I think that you can completely remove the 'if / switch' statements and call only the methods which are automatically bound based on the value of the expression.

There are languages ​​that implement such words. Right from now I am familiar with the compiler generator tool called elegant.

In this type of language, a simple factual algorithm may look like:

  Facts (value: IT): int condition values ​​<0 {{" Value {return value} = 0}: return {0 return} fact (value = 1): difference {return1} facts (value: int): int {return value * fact ( Science - 1);}  

sql - MySQL: Alternatives to ORDER BY RAND() -

मैंने MySQL के ORDER BY RAND () फ़ंक्शन पर कुछ विकल्प पढ़ा है, लेकिन अधिकांश विकल्प का केवल एक यादृच्छिक परिणाम की आवश्यकता है, जहां पर लागू होते हैं।

क्या किसी को कोई भी विचार है कि एक क्वेरी को अनुकूलित करने का तरीका क्या है जो कई यादृच्छिक परिणाम देता है, जैसे कि:

  का चयन करें यू.आई.डी., पी.फ़ोटो यूजर यू से, प्रोफाइल पी WHERE p.memberid = u.id और p.photo! = '' AND (u.ownership = 1 या u.stamp = 1) आदेश द्वारा रैंड () सीमा 18  

यह एक विकल्प है, लेकिन यह अभी भी RAND () का उपयोग करने पर आधारित है:

  SELECT u.id , पी। फोटो, राउण्ड (रैंड (* * x.m_id) 'प्रयोक्ता यू, प्रोफाइल पी, (चयन MAX (टी.आईडी)' एम_आईड 'से उपयोगकर्ता टी) एक्स जहां पी। मेम्बरिड = यूआईड और P.photo! = '' AND (u.ownership = 1 या u.stamp = 1) ORDER द्वारा rand_ind LIMIT 18  

यह थोड़ा अधिक जटिल है, लेकिन random_ind का बेहतर वितरण प्रदान करता है मान:

  SELECT u.id, p.photo, FLOOR (1 + RAND () * x.m_id) 'rand_ind' उपयोगकर्ता से, प्रोफाइल पी, (चयन करें MAX (टी.आईडी) - 1 'एम_आईडी' से उपयोगकर्ता टी) x जहां पी। मेम्बरिड = यू.आईडी और पी.फोटो! = '' और (यू.नरशिप = 1 या यू.स्टैम्प = 1 ) आदेश रैंड_आईडी LIMIT 18

which is a better language (C++ or Python) for complex problem solving exercises (ex. Graphs)? -

I'm trying to work on some problems and algorithms. I know C ++ but a friend told me that it would be better if done with Python. As it will be for fast and to develop and spend less time programming details

edit 2 : I plan to use Python-graph lib from Google-code, please provide example code if you have used it.

Edit 1 : Faster - less time & amp; Amp;

I thank you for your help! It seems that you are searching for Python, because you can:

• Focus on algorithms and do not worry about other details like memory management.
• Do more with a lower code
• Syntax is working with almost the phonetic code.
• List, Tuple, has been made great in language support for the list, etc ..

But more specifically ...

If you mean speed of development , then Python was selected from better .

If you call speed of execution from better , then C ++ .

java - Appengine performance problem. Same site 10x faster accessing from appspot than from my domain -

This is really awkward for me and it's happening in a real problem.

I am creating a site using the appenjun (java) scala and it is actually working really slow when it comes from my domain:

  / Latest 200 1505ms 2325cpu_ms 1586api_cpu_ms 4kb  

'has purchased the domain through Google apps, so it is automatically configured. I can not understand how this could be ... Can this be something in my code? Or is there anything about this configuration?

The problem is completely reproducible, and if you need to see the speed difference, then it is worth noting just by reaching the site. These links are:

Thanks a lot.

It is most likely that you sent your first request to a new runtime, which started It took some time, however, the request for the Apespot domain was already done by the hot-up runtime (probably same). Try to send several requests and take minimum in each domain - there should be no statistical significant differences.

variables - C# initializing an integer data type -

How to start a variable of data type integer, in C # The problem is that the variable has to store an integer with values ​​from 1 to 4.

You can use an enum, which by default is typed as Int32 (int) The public enum MyEnum {first value, second value, third value, fourth value}

Obviously you can call enum anytime you want , And give meaning to the four values ​​namely name. After that you can just start an example: -

  var myValue = MyEnum.FirstValue;  

WPF Data Binding and Data from SQL DataTable - need some ideas -

I have a lot of WPF windows on them, I write some code on them, which adds UI control and data, something like that :

  public class addressWindow {public string addressID {get; Set; } Public string Addr1 {get; Set; } Public String Addr2 {get; Set; } Public string zip {get; Set; } Public String City {Received; Set; } Public String Mobile {Received; Set; } Public string fax {get; Set; } Public string country {get; Set; } Public String Email {get; Set; } Public string phone {get; Set; } Public Bull ISS System {Received; Set; } Enable Public Buttons {get; Set; }} Private Zero BindInCode () {var Address = New Address Window {// AddressID = "110", // Addr1 = "Kaunas", // Addr2 = "Jonavos", // ZIP = "8987", // City = "Mestas", // mobile = "869985868", / / ​​FAX = "87998", // country = "Lithuania", // email = "emailas@ree.lt", // phone = "37598288" , // IsSystem = true, // enabled = false}; Binding binding = new binding (); Binding Source = address; Binding.updatestrategor = updateSource Trigger Property changed; Binding.path = new propertypath ("address id"); This.db_AddressID.SetBinding (TextEdit.TextProperty, binding); Binding = new binding (); Binding Source = address; Binding.updatestrategor = updateSource Trigger Property changed; Binding.path = new propertypath ("AdR1"); This.db_Addr1.SetBinding (TextEdit.TextProperty, binding); ...............}  

Now I want to create some universal simple engine for filling data values ​​(value to my square properties from datatale Please, specify) ). Does anyone know how to do this ..? For example, there is a way of specifying value by the names of properties, say that the name of my property is equivalent to the name of the column from the Datasro. Is it possible to do something like this in WPF, or do not I have to manually do every window Assign value to?

Personally, I have used the code generation to work, but you can use it for Jimmy Bougard, what about you Talking it's on and off.

(rails) weird problem with url validation -

I am trying to see if a url exists or not. Here's my code to do this: url and url.match (URI :: regexp (% w (http https)) Check if # header result:

  Validate: Registered_domain_name_ exists private def register_domain_name_exists Case Net :: HTTP.get_response (URI.parse (url)) When Net :: HTTPSuccess, then the correct else errors.add (URL: "url is not present") and false termination # DNS failures errors .add (: url, "url is not present") and wrong end end  

However, this code is failing, it says that there is no legitimate website. In addition to this, knowing that I also try this URL, and also failed. Then, I know that this can not be possible. What is wrong with my code ??

< / Div>

Each example URL given by you is a redirect (is the HTH status code) 301 or 302). Your code is only considering success for HAB status code 2xx only. Add another case:

  when: NetResources: HTTPRedirection true  

Update: Note that the use of HTTP HEAD instead of GET will transmit low data across the network .

  Yuri = URI response (URL) = Net :: HTTP.start (uri.host, uri.port) {| Http | Http.head ('/')}  

How to put pointer in the desired place in a stream using PHP? -

Currently, I am creating a data parser using PHP through Telnet connection. I have had a problem: I should put the pointer in a stream (not to the end of the data) in some places, but it is impossible to use the function () function using the stream. Please tell me that I have this problem How can I solve this?

This function moves your stream cursor to the desired location:

  function Strikers (and $ FP, $ offset) {for ($ i = 0; $ i & lt; $ offset; $ i ++) fgetc ($ fp); } // Use this as: $ curPos = 459; $ Desired POS = 1345; MoveStreamCursorTo ($ yourstream, $ desired POS - $ curPos);  

Please check it and report your results.

user interface - java filechooser -

I am working on a project, in Java, where to select a file to upload the user through jfilechooser Will be. Is there any way to make the text file read-only so that you can not select by simply clicking on the file, and typing in the text field. I hope I have clarified my problem, D

If your intention is to ensure that That the user has selected a file instead of the directory (your answer to other answers), you can use the FileChooser.setFileSelectionMode (JFileChooser.FILES_ONLY); However, this is the basic setting when you instantiate the file selector, so unless your code changes at some point, you should not have to set it explicitly.

locking - how to prevent opening serial port on linux by foreign application? -

Using locking is not acceptable in case of "bug" in port driver.

So you have to lock other processes by opening a device file, but file locking is unacceptable. .

Well, you can change the device file to some non-standard, so trying to open / dev / ttyS0 will not move your toes on your toes.

Create XML file dynamically in Iphone -

I want to dynamically create an XML file for my iphone application.

Example:

  // Serializer XMLWriter allocate  
  
 XmlWriter = [[XMLWriter alloc] init]; // write XML elements [xmlWriter write start element: @ "root"]; [XML Writer writes: Cracker: @ "Text Content for Original Elements"]; [XmlWriter Write EndElement]; // get the resulting XML string NSString * xml = [xmlWriter toString];  

This generates the following XML string:

Mysql php update function problem -

How do I create a php code to fallout for mysql?

If Active = 1 to Current amount + 2000

 Thanks for helping people 
 

The SQL query is as follows:

  update tablename SET zodiac = amount + 2000 WHER e active = 1;  

How do you implement it in PHP, depending on which database driver you are using.

For example, using mysqli :

  & lt ;? Php $ link = mysqli_init (); Mysql_real_connect ($ link, $ host, $ username, $ password, $ db_name); Mysqli_query ($ link, "update tablename SET zodiac = amount + 2000 WHERE active = 1");  

java - How does reflection affect Perm size? -

I understand that the magnitude size is used to store meta data, including byte code, static content, etc. Are there.

My question affects the finite size of the reflection, if ever this happens, I mean that if the Program-A uses the normal way of running objects and Program-B uses all the reflections, How will both programs compare the perm-size ?

When you execute the code, the permity will increase which will load new sections < / Strong> or internal strings reflection sections should be loaded to make sure I am not convinced that the reflection API partially uses strings, but it is not difficult to find needed.

For example, the method getDeclaredMethod (string name, class

  random random = new random ()    
; while {true} {try {X.class.getDeclaredMethod (toBinaryString (random.nextLong ());} hold (exception e) {}}  

It will not make any difference in the real world application.

Is it enough to clean up my contact form?

Thank you.

It seems that civilization and average is better than inputvalidation. Personally I also like to handle the input type. In my base controller I have a valid date of input, email address etc. If you add such validation for your current verification, then you are managing IMO well.

.net - C# User Controls: access controls properties -

I have created a control and added a textbox in that control, I can control that control on the .aspx page

< Pre> and lt;% @ register Src = "../ user control / account circuit." TagName = "SearchControl" tagfix = "CSR"%>

and

  & lt; Csr: SearchControl ID = "AccountSearchControlBox" runat = "server" OnSearchButtonClick = "RetreiveAccounts" />  

On the .aspx.cs file, I want to use the value of the textbox inside the user control ... How to get it?

Add a public property to AccountSearchControl.ascx

  Public string text box text {get {return TextBox1.Text; } Set {TextBox1.Text = value; }}  

By default, you have protected visibility in all the controls located on the page (take a look at AccountSearchControl.ascx.designed.cs to see), so you have to expose a method to access the text box of your page.

.net - Why use FinalReleaseComObject instead of ReleaseComObject? -

I know that the original difference in the form of ReleaseComObject only decreases some counter and FinalReleaseComObject decreases it to zero

So what I've usually heard, call FinalReleaseComObject because then you are certain that the COM object actually released

But this makes me wonder, is there a point right over this counter? Do not you break that system, if you always call the last com object if you call that counter on a ReleaseComObject Not the first, so there is no reason for this?

This may be the reason for having more than one when it should not be?

Thanks in advance.

PS: My COM experience only consists of using Excel Interop. Not sure that this question is local for the domain (i.e. the external office interop, finalReleaseComObject is not often used).

Update 1

Donation Talk When you are using ReleaseComObject as I think, this is a normal way. I think that if you do this then it should work fine. In a comment for the author, it is reported to anyone that it releases "code"> ReleaseComObject until the release actually (since 2006, so it is calling FinalReleaseComObject Is similar to). But he also says that it can be dangerous.

If you really want RCW to make a release () call at a particular point in the code, you can call the Release Com Object () in Rob until the global value reaches zero. Are there. It should be ensured that RCW will call the release () However, if you do so, it is warned, when other managed references try to use that RCW, it will create an exception. "

I believe this is a good idea to actually call not always the end of the com subject Because you can cause exceptions elsewhere, as I have seen it now, you should call it only if you can make sure that you can. FinalReleaseComObject is a hack of a best practice. >

Some prelude ...

A runtime callable cover (RCW) only IUnknown. Call AddRef, which is once on an unmanaged COM interface that wrap it up. However, an RCW is also managed by a managed number. Maintains a separate count of the number of Rbhon it here Arseedyu. It has been reduced by calling Marshall a different country managed contexts. Release Com Object When count of managed references reaches zero, then call RCW IUnknown.Release at once unmanaged COM interface.

Marshall.FinelRelicom object takes a managed reference number for zero with a call, and immediately unmanaged IUnknown.Release method wrapped in this way (assuming that the managed reference count was not already zero ).

Why both are martial? Release Comm Object and Marshall FuneralRelease Com Object? Calling Marshall.FinalRailCom Object Bus avoids writing a loop that calls to Marshall. Unless it does not indicate unless you want to indicate that you have finished using actually the COM object now .

Why use Marshall either. Release Com Object or Marshall: FinalRailCom Object? There are two reasons for which I know:

The first thing to do is to ensure that unmanaged resources (such as file handles, memory etc.) are used by wrapped COM objects as soon as possible unmanaged Results of calls as a result of the IUnknown.Release () method.

The second is to make sure that thread has unmanaged IUnknown.Release () method under your control, and there is no final form of thread.

In these martial methods, the end of RCW will finally call the unmanaged IUnknown.Release () method, after some time the RCW trash was collected.

objective c - iPhone animation efficiency solutions, layering questions -

I'm working on writing a basic app. It uses minimal touch input, and most fancy games play animation. There is not much animation, but the way it is currently done is extremely inefficient and uses a lot of memory.

This scene is divided into two parts, below 1/5 only There is an image that never changes. This is the rest where the animation plays. It is currently loading 32 images in one array and then running through them (8 FPS). This goes 4 times through each animation Photos are not very big, but they are still big. I was also thinking that to store them as the best file format, both according to the overall size and requirement of the overhead.

This is a simple straightforward approach, and it works, but it does not seem to be remembered, it uses too much.

My suggestion was to split the animation into some layers, because there are some things that can be done differently:

• Make the background a static image, therefore It does not have to be a part of the animation.
• Excluding some "dude", such as graphs and running a progress bar and making them partially transparent layers up or down, the animation will also open the door Till the creative self Ntrta is in the future for me.
• Exclude the above text and use the iPhone to display the text instead. Is it better to drag an image or load an image with text in the iPhone? Mainly being a web god, I find it silly to load any image.
• What is left after these things are taken out as an animation, which will be very small

So overall, we have 1 static background, 3 -5 are looking at small animations, and a big one. Can I use layers to separate these elements, and is it more dependent on the iPhone to attract the final image? This was the place where I thought I could make this race a little better, it seems silly to merge into a bigger picture, so that you can flip like a flip book, when you're in the app-wide Can load some small elements, and do things a little bit more efficiently

Or, am I completely fulfilling it and there is a better way to go about it?

EDIT: I am browsing around and it seems that using layers will be more efficient. I have another question, though. As each frame of the animation it is better for its file, and has been loaded into the array for animation, or is a huge phantom sheet image with all the frames, and using the coordinates of the iPhone from within the phantom sheet Is it better to capture each frame as a program? <2 p>

Edit 2: We've done everything since then,

< P> Assuming that the total animation sequence is stable, you want to compile it as the best movie, and use the Movie Player Framework to play it:

  MPMoviePlayerController  

This will allow the iPhone to use custom hardware for display, and the use of the battery will be less. As a user interaction, you need to set Movie Controlmode property so that the user is not able to interact with the movie.

MPMovieControlModeHidden Do not display any control This mode prevents users from controlling playback.

Available in iPhone OS 2.0 and later.

declared in MPMoviePlayerController.h.

compiler errors - Autohotkey choking on curly brace in simple If's -

I have a problem with Autohotkey, telling me that there is an absence (in front of another) where I think It is that my code is absolutely fine (and before that I changed the window from related to pidin to dirt) till then worked.

WinActivate} else {; Closing the closing bracket AH in front of the other ... WinMinimize}} and; do something; Accessories with friends list; [...]} Return  

I am afraid that I am seeing some idiots, but I can not get this work.

If I'm not mistaken, then a true brace style is only if there is a statement, with compounds like IFWinExist Is usable. From manual: "A true brace (OTB) style can optionally be used with those statements which are expressions (but not traditional if-details)." Ie You have to use WinExist () form, if not , IfWinExist.

How do I edit SSIS package files? -

I have a DTSX file in the project that I am taking. I have Visual Studio 2005 Pro, but it just opens XML file as SQL Server Management Studio 2005 does the same

I have seen people open these files in some workflow-ask formats; Business Intelligence Development Studio comes to mind

Is this a part of Visual Studio or SQL? Is it to be bought separately? Can I open this file in a more useful way with the tool?

From Business Intelligence Studios:

File-> New Project-> Integration Service Project

Now there is an SSIS package folder in the Solution Explorer, right click and select "Add existing package", and there is a drop down that can be changed in file system, and very bottom box Allows you to browse the file. Note that this will copy the file from where it is in the directory structure of the project.

css - Stacking CSS3 Structural pseudo-classes -

While practicing various scenarios in which CSS3 pseudo-classes and selectors can be useful, I run into something Detect what I can not do!

Here's the position I want to modify the first non-empty paragraph : first-of-type :: first-letter for the block of text. I'm not sure whether the pseudo classes can be stacked though. Here's what I came up with (does not work, of course)

 . Colonel-Body & gt; P: No (: empty): first-of-the-type :: first letter {...}  

Looking at the following markup:

  Lt; Div class = "article-body" & gt; & Lt; P & gt; & Lt; / P & gt; & Lt; P & gt; "T" in this article should be affected. & Lt; / P & gt; & Lt; / Div & gt;  

The only estimate is that I can not stack on pseudo-orbits (i.e. :: no () and: first-type types).

Any ideas for how this can be accomplished?

c# - Replace Switch/Case with Pattern -

I have the code behind the code three times in this example. Every time the switch is shutting down the option that is sent to it. Each time the code inside the case is exactly the same, apart from this the parameter is left on the basis of case. Is this the best way to do a switch / case and method? Should I think of using some type of design method to avoid repetition switches / case structure?

  string option = dropdownlight. Selected value. Toasting (); Switch (option.ToUpper ()) {case "ALPHA": // repeat code method here; The only change parameter is the brake; Case "Bravo": // repetitive code method here; The only change parameter is the brake; Case "Charlie": // Dual code method here; The only change parameter is the brake; Case "DELTA": // Dual code method here; The only change parameter is the brake; Default: Break; }  

The compilers are very good at switching / making case-making; The CLR will probably turn it into a lookup table or something will be faster, so it's recommended to roll your own version like Henk Holterman, what I would recommend. CLR can do a better job than you choose a better algorithm.

If this is the issue of beauty or maintenance, and you have many switches / cases about the same class doing the same thing, then one way to improve it is to use all the procedures related to the same "case" Is included in the frequency of its class, such as:

  class MyOption {public static text only MyOption alpha = new MyOption (1, 10, "alpha text"); Public Static Readonly Myoption Bravo = New Prepress (2, 100, "Bravo Text"); Public Static Readonly Mioption Charlie = New Myoption (3, 1000, "Charlie Text"); // ... Other Options ... MyOption default for public static = New MyOption (0, 0, blank); Public MyOption (int id, int value, string text) {this.ID = ID; this. Value = value; this. Text = text; } Get public int id { Private set; } Public int value {get; Private set; } Public string text {get; Private set; In your class / control / page:  
  Fixed MyOption GetOption (string option name) {switch (optionName) {case "ALPHA":} Return MyOption.Alpha; Case "Bravo": Return MyOption.Bravo; Case "Charlie": Return MyOption.Charlie; // ... other options ... Default: MyOption return.Default; }} Private MyOption GetOptionFromDropDown () {string optionName = GetOptionNameFromDropDown (); Return GetOption (optionName); } Private string GetOptionNameFromDropDown () {// ... your code ...}  
 
 Then you can start churning events and other methods: 
 
  Private Zero Control 1_SomeEvent (Object Sender, EventArgs e) {MyOption Options = GetOptionFromDropDown (); DoSomething (option.ID); } Private Zero Control 2_SomeEvent (Object Sender, EventArgs e) {MyOption Options = GetOptionFromDropDown (); DoSomethingElse (option.Value); }  
 
 Of course, this is just a useful pattern, if you have  many  of these switches / cases that you want to refresh in one. If you have only one switch / case, then you are just going to eliminate many  more  code, so leave it alone! 
 
 Other possibilities to improve include Maintabilityability: 
 
 
 Change the string in an Enum type (Convert optionName by using Enum.Parse); 
 
 Moving all MyOption / GetOption stuff into your class (if you have many categories / controls / pages that need to be operated on the same set of all options); 
 
 If you really need to call a different method for each, add a method representative for the MyOption class; 
 
 Put a direct reference to MyOption example, if possible, to your DropdownList or other control store. 
 
 
 It's about it It's easy to write, it's easy to understand, it's easy to keep up, if you have many switch / case creation, it will save you time, And it still allows CLR to optimize the best possible. The only cost is small amounts of memory needed to keep those redone areas. 
 

python - Solving a cubic equation -

I am writing as part of a program, I need to fix a cubic equation (a numerical root Finder):

  a * x ** 3 + b * x ** 2 + c * x + d = 0.  

I'm trying However, consider the following code (this is Python but this is very common code):

  a = 1.0 b = 0.0c = 0.2 - 1.0 d = -0.7 * 0.2 q = (3 * a * c - b ** 2) / (9 * one ** 2) r = (9 * a * b * c - 27 * a ** 2 * d - 2 * b ** 3) / (54 * A * * 3) print " Q = ", q print" r = ", r delta = q ** 3 + r ** 2 print" delta = ", delta # Here the delta is less than zero, so we use other equations from the article: rho = (-q ** 3) ** The hypothetical portion for ** 0.5 # x1 is insignificant because it is s_real = rho ** (1./3.) T_real = rho ** (1./3 print "s [real] = ", S_real print" t [real] = ", t_lr x1 = s_real + t_real - b / (3. * a) print" x1 = ", x1 print should be" zero: ", a * x1 ** 3 + b * X1 ** 2 + c * x1 + d  

but output is:

  q = -0.266666666667r = 0.07 delta = -0.014062962963a [Real] = 0.516397779494 t [real] = 0.516397779494x1 = 1.03279555899 should be zero: 0.135412149064  

Then the output is not zero, and therefore x1 is not really a solution in Wikipedia article Mistake?

ps: I know that numpy.roots will solve this kind of equation, but I need to do this for millions of equations and so I need to implement it to work on multiplier Arrays of.

javascript - Ext JS -DOM Query question -

Fix another DOMQuery question I think the EXT API document is slightly below it.

I have multiply fields inside my form panel, but there is a need to find the person who got the title title of 'test results'. Does anybody know if Ext does a helpful job to do something like this or me

formPanel.findByType ("fieldet", true) Like soming will need to be done, and then for each loop for that particular title ...?

Thank you!

Using Ext.form. Find the method of formPanel:

  Var fieldSets = formPanel.find ('title', 'test results');  

Keep in mind that Return Value is an array of items.

A bit more crazy way of using the method of Ext.util.MixedCollection:

var fieldSet = formPanel.items.find (function (item) {return items Examples of: ext.form.FieldSet and item.title == 'test result';});

The return value here is only the first item found.

c# - What is the recommended way to manage a strong-name key pair for an open-source project? -

I manage an open-source project and want to sign Binaries released in this project's binary package. I am I use visual studio csproj and sln files to distribute these files as a part of the source package of the project and manage my project.

How can I sign my production binaries and do not distribute the snk key-pair file to me? If I use Visual Studio to sign assemblies, then each project file requires a copy of the key-pair to create it now

Edit : Another warning is that in some assembly, I have no problem sharing the key pair. Access project grant friend via InternalVisibleToAttribute , and create those friends through a project reference. As a result, such assemblies will have to use a strong name while mentioning a signature assembly. However, if the key-pair is not distributed, how can the end-user make the source and maintain the project relationship? If a floating key-pair file is used, the public key token of signed assemblies, by breaking the InternalsVisibleToAttribute references,

You must not deliver keypair The strong name is to verify that the new version of the assembly comes from the same publisher.

If any other developer wants to add your project to the branch, then it will generate its keypayer and it will effectively show that its version is not with you so that other parliaments that depend on you Will not load until they are compiled again. It is not always convenient but it protects you from someone who issues a malicious version of the assembly and secretly distributes it.

Writing binary files using C++: does the default locale matter? -

itemprop = "text">

I have a code that uses binary files using fstream with binary flag set and read without using formatted I / O functions and I write works correctly on all the systems I have ever used (bits are actually expected in the file), but they are basically all U.S.. Are english I am thinking of the possibility of being modified by codecvv on different systems for these bytes.

It seems like the formatted I / O using standard using spreadsheets / sgetc in the virtual world. These will lead to overflow or underflow functions in Streambuff, and it looks like these leads for things that go through some codecvt (e.g., see 27.8.1.4.3 in C ++ standard). The build of this codecvt for the basic file is specified in 27.8.1.1.5. From this, it seems that the result will depend on the basic file that returns the default_filebuf.tlock ().

So, my question is, can I assume that using a character array made through a system on any system? Verbally using any ifstream.read on any other system, even if any locale configuration is using any person on their system? I will make the following assumptions:

1. The program is using default locale (i.e., the program locale setting itself is not changing).
2. The system is both CHAR_BIT 8, store files in the form of a single bit order, octets, etc. within each byte.
3. The binary flag is set in the stream objects.
4. We do not have to worry about any endless differences at this level. If any byte is interpreted as a multi-byte value in the array, then the final conversion will be handled as necessary.

If the default locale pass is not guaranteed, through this content attached to some system configuration (I do not know, Arabic or something else), write binary files using C ++ What is the best way?

This should be fine on Windows, but on other OS you can get a line end (such as security) Should also be seen. The default C / C ++ locale is "C" which is not depending on the system locale.

It is not guaranteed as you know the C / C + compiler and their target machines are very different. If you keep all those beliefs, then you are waiting for troubles. There is a negligible overhead to change the locale, unless you try to make it hundreds of seconds per second.

performance - Erlang : Which is more efficient in this scenario - using try catch or case statements? -

Say I have some functions in Arlon (1) which {ok, result} The function was successfully executed and {error, "error region"} if there was an error

Now in another function fn2 () I call fn1 () And I need to check the result of fn1 and if it is {ok, result} , then go ahead.

I thought, I can do this or try to catch it from any case but ability is my main concern and I would like to know that the two methods given below Which of the following is more efficient:

try-catch method

  fn2 () - & gt; Try {OK, result} = fn1 (),% Hold something with the result Catch OK: Duration - & gt; Period; Exit: reason - & gt; {Exit, reason}; Error: cause - & gt; {Error, {cause, erlang: get_stacktrace ()}} end  

case method

  Fn2 () - & gt; Res = fn1 (), Res of the case {ok, Result} - & gt; Do something right with the result; {Error, reason} - & gt; The end of the reason  

The case method will be more efficient, because it is only pattern match, And not include making call stacks and accessories.

In both instances, you are going to handle "error" locally, so there is no point in trying to catch up. What you can sometimes see is something like this:

  fn2 () -> {OK, RESULT} = FN1 (),% What is the good stuff with the result  

Here is the intention that if you throw fn2 () a badmatch, if fn1 () fix Do not let anyone handle you "above" problem. Like it can kill your process, and make your supervisor a new one.

google app engine - Grails AppEngine file upload using GAEVFS -

I am working on Grails web application and need to upload files. I have a form (simplified):

  & lt; G: form action = "save" method = "post" enctype = "multipart / form-data" & gt; & Lt; Input type = "file" id = "image" name = "image" /> & Lt; Input class = "save" type = "submit" value = "create" /> & Lt; / G: form & gt;  

and controller code should not (I know that this controller, but it's just to make it work and be better designed):

 < Code> def save = {GaeVFS.setRootPath (servletContext.getRealPath ("/")); FileSystemManager fsManager = GaeVFS.getManager (); File object tmpFolder = fsManager.resolveFile ("gae: // WEB-INF / upload_files"); If (! TmpFolder.exists ()) {tmpFolder.createFolder (); } // I need the code here to save the image in GAEVFS via bigtable}  

Then I have two problems:

One. Because when saving to the button is pressed an exception it tries to use tries to save the Apache Commons FileUpload system file

I disable it

The exception is:. Java. Lang.NoclassDefFoundError: java.rmi.server.UID is a restricted class. Please refer to the Google App Engine Developer's Guide for more information. com.google.appengine.tools.development.agent.runtime.Runtime.reject (Runtime.java:51) on org.apache.commons.fileupload.disk.DiskFileItem.

On commons.fileupload.disk.DiskFileItemFactory.createItem org.apache.commons.fileupload.FileUploadBase.parseRequest (DiskFileItemFactory.java:196) (FileUploadBase.java:358)

B. I need the code example to save the image through Gaevfs I've seen examples in GaeVfsServlet but I see now how much right do not know that my case is this. Any kind of help is welcome

GaeVfsServlet URL:.

I came across this very problem and I am using a grails plugin called ajaxuploader To get a solution to the problem - Using the Commons File Upload API at all is available for your controller in the form of an InputStream object and doesnt upload that file
