Executive summary: You can run up to four xor ax, ax instructions per cycle as compared to the slower mov immediate, reg instructions. Details and references: Wikipedia has a nice overview of register renaming in general: http://en.wikipedia.org/wiki/Register_renaming Torbj¨orn Granlund's timings for instruction latencies and throughput for AMD and Intel x86 processors are at: http://gmplib.org/~tege/x86-timing.pdf Agner Fog nicely covers the specifics in his Micro-architecture study: 8.8 Register allocation and renaming Register renaming is controlled by the register alias table (RAT) and the reorder buffer (ROB) ... The µops from the decoders and the stack engine go to the RAT via a queue and then to the ROB-read and the reservation station. The RAT can handle 4

No. Moreover, you should not need to. You can use user notifications to be able to send a single message from the server to all instances of your app across all the user's devices.

"mod 256" is the remainder after division by 256. In binary, this turns out to be the lowest 8 bits (because 256 is 2 to the 8th). This is just like "mod 2" gives you the least significant bit (0 or 1). On (in decimal, base 10), "mod 100" gives you the last two decimals ( 2013 mod 100 => 13).

Hooking into the built-in commands (like " and Ctrl+r) is difficult, because Vim then is in a special sub-mode where it waits for the register name. I use the following "" mapping (which normally is a no-op) to refresh my memory: " ["x][N]"" List contents of the passed register / [N] named " registers / all registers (that typically contain " pasteable text). nnoremap <silent> <expr> "" ':<C-u>registers ' . (v:register ==# '"' ? (v:count ? strpart('abcdefghijklmnopqrstuvwxyz', 0, v:count1) : '"0123456789abcdefghijklmnopqrstuvwxyz*+.') : v:register) . "<CR>"

I believe you need to quote your values like so: $Query = "INSERT INTO `sito` (`user`, `password`) VALUES('$Escape', '$Password')"; Also you might want to check out mysqli or PDO instead of using mysql_* functions.

From an efficiency standpoint, it would seem that using the controls element in web.config would be better, because it is cached once when the application starts; whereas the page directive Register will be processed every page request.

Visual Studio enumerate the HKEY_LOCAL_MACHINESOFTWAREWow6432NodeClassesTypeLib registry key to fill the COM tab. Drop Wow6432Node if you use the 32-bit version of Windows. So what's missing is that you forgot to ask Regasm.exe to register the type library. You need to also use the /tlb option.

Found the answer. It appears that library was build in .net 2, and it can not appear here c:WindowsMicrosoft.NetassemblyGAC_MSIL because it is GAC for assemblies build in .net 4 and higher. So I just take library build in .net 4 and register it using gacutil from c:Program Files (x86)Microsoft SDKsWindowsv8.0AinNETFX 4.0 Toolsx64

(Presumed) Problem: movq $1, -72(%rbp) moves the integer value 1 into memory, which, when represented as a floating point number is something extremely small. When you multiply 'x' by this number the result is so small that it's rounded to 0. Potential Solutions: Move a floating point immediate value of 1.0f into memory, instead of 1. I can't say exactly how to do this because I don't know what assembler you're using. Like Brett Hale said, convert the integer into a floating point number. There's probably a million ways to do this, so just Google something like "SSE Integer to Float", and you'll a bunch of results.

By using gcm sender id,you will use in android ie client side and server browser api in server side say php side. So when a device opens,it will create gcm register id at server side and intermediate is gcm account and it will monitor the device.so you can send notification from server to client. For same device,only unique gcm registration id will be generated. See this tutorial http://www.androidhive.info/2012/10/android-push-notifications-using-google-cloud-messaging-gcm-php-and-mysql/

I use the code below. The code assumes that the XMPP server is running locally (localhost). The createAccount method is creating internally a Registration packet and sends it through the connection. public static void main(String[] args) { XMPPConnection.DEBUG_ENABLED = true; XMPPConnection connection=null; try { ConnectionConfiguration config = new ConnectionConfiguration("localhost", 5222); connection = new XMPPConnection(config); connection.connect(); AccountManager accountManager = connection.getAccountManager(); if(accountManager.supportsAccountCreation()) { accountManager.createAccount("user1", "user1pw"); } else { ... } } catch (Exception e) {

There might be one register, multiple registers, or even no registers associated with any given C variable at any given point in time. You'll have to inspect the disassembly to see what's going on. Why not just print my_reg to see the value? l *$pc will list the source code around the current instruction being executed.

You need to use authenticate() first, before calling login(). from django.contrib.auth import authenticate, login if(form.is_valid()): form.save() new_user = authenticate(username=form.cleaned_data.get('username'), password= form.cleaned_data.get('password')) login(request,new_user) return redirect('/dashboard/') From Django docs: When you’re manually logging a user in, you must call authenticate() before you call login(). authenticate() sets an attribute on the User noting which authentication backend successfully authenticated that user (see the backends documentation for details), and this information is needed later during the login process. An error will be raised if you try to login a user object retrieved from the database direct

The thing you want is pretty simple, but you need to add few additional information to your code, because you're writing x86 assembly and not any high-level language like Java or C#. First solution is to keep counting in ecx and compare it with array length. ... arrlen: .long (arrlen - myvar)/4 ... xor %ecx, %ecx loop: movl $0, %edi movl $myvar(, %ecx, 4), %eax pushl %ecx ... //fill other registers ... int $0x80 popl %ecx incl %ecx cmpl %ecx, arrlen jne loop Another way is just to check value loaded. After calling system call, you can't be sure that it won't affect register values (some system calls return information in same registers as used for parameters). You can simply save it on stack, or faster, do comparasion direcly in memory. pus

I don't think you can listen to the drag event using jsPlumb. YUI has a Drag class which is the one that fires the drag event. Usually you'd create an instance of this class and that would be enough to make your node draggable. var dd = new Y.DD.Drag({ node: '#foo' }); dd.on('drag:drag', function () { // do something }); But jsPlumb creates a hidden Drag instance and keeps it to itself. There doesn't seem to be a way to retrieve that Drag instance. My recommendation would be to open an issue in jsPlumb's GitHub asking for a way to do this.

Manual mode changes are not an efficiency goal on the ARM. Typically, manual mode changes are only done to setup stacks, etc at boot or initialization time. The cpsr is the active copy. Why do we have a banked lr register but not the current pc? The spsr is a banked cpsr for a different mode; just like the banked lr is the pc for a different mode. The banking is so that the exception state can be transparent. The spsr is banked as an interrupt or data abort may occur in any mode; we need to save it so that we stack execution correctly. The normal unbanked user mode never stacks with another mode. mode changes are done automatically in exception conditions. The mode registers are setup to make exception handling very efficient and flexible. Manual mode changes are not highly conve

This is how clang on my OS X machine does it -- annotated for clarity: # this is the constant '(double)2.5' LCPI0_0: .quad 4612811918334230528 ## double 2.500000e+00 ## (0x4004000000000000) leaq L_.str(%rip), %rdi # arg1 = format string address movsd LCPI0_0(%rip), %xmm0 # float arg2 = 2.5 movb $1, %al # number of floating-point arguments callq _printf .section __TEXT,__cstring,cstring_literals L_.str: .asciz "%f " # here's the format string

According to the Intel manual, you get an "undefined opcode" exception: mov — Move { Protected Mode, Real-Address Mode, Virtual-8086 Mode, 64-Bit Mode} Excpetions #UD If attempt is made to load the CS register.

This is what it looks like in JNA: public interface MyLibrary extends Library { /* StdCallLibrary if using __stdcall__ */ interface MyCallback extends Callback { /* StdCallCallback if using __stdcall__ */ void invoke(/* fill your parameters here*/); } DWORD RegisterCallback(HANDLE handle, int type, MyCallback callback); } ... MyLibrary lib = (MyLibrary)Native.loadLibrary("mylib", MyLibrary.class/*, options*/); MyCallback callback = new MyCallback() { public void invoke() { System.out.println("Success!"); } }; HANDLE h = ...; int type = ...; lib.RegisterCallback(h, type, callback); ... Suffice to say the JNI version is quite a bit longer, plus you have a native compile step to account for.

Simple and very fast, but requires 4KB of table space: _mm_shuffle_epi8(a, mask_lookup[bitvector]); where you simply store all 256 possible shuffle masks in a table indexed by the bitvector.

Information found in the phalcon forum: http://forum.phalconphp.com/discussion/344/multi-module-wildcard-annotation-router One has to register the namespace with the PhalconLoader instead of the throught the modules loader. $loader = new Loader(); $loader->registerNamespaces( array( 'AppsBackendControllers' => __dir__ . '/../apps/backend/controllers/' ) ); $loader->register();

By reading the documentation from LibModBus, I think you're missing a call to modbus_connect. Try connecting before reading registers: ctx = modbus_new_rtu("/dev/ttyS0", 115200, 'N',8,1); if (ctx == NULL) { fprintf(stderr, "Creation failed: %s ", modbus_strerror(errno)); return -1; } if (modbus_connect(ctx) == -1) { fprintf(stderr, "Connection failed: %s ", modbus_strerror(errno)); modbus_free(ctx); return -1; } Also, remember to modbus_close and modbus_free your context before exiting due to further error conditions. For example: rc = modbus_read_registers(ctx, 0, 10, tab_reg); if (rc == -1) { fprintf(stderr, "%s ", modbus_strerror(errno)); modbus_close(ctx); modbus_free(ctx); return -1; }

You can create style sheet for VML using the below code document.namespaces.add("v","urn:schemas-microsoft-com:vml"); var style = document.createStyleSheet(); style.addRule('v\:*', "behavior: url(#default#VML);"); This code will work in IE 7 & above, but I have not tested in IE 6

Try this if ( function_exists('register_sidebar') ) register_sidebar(array( 'name' => __( 'Right Hand Sidebar' ), 'id' => 'left-sidebar-login', 'description' => __( 'ThemeMyLogin Widget Area' ), 'before_title' => '<h1>', 'after_title' => '</h1>' ));

Part 1: In order to check if the registration id is refreshed to a new one or it is still the same, I plan to re-register. Now, if you see the second point under the heading Enable GCM on Architectural Overview page, it says: Note that Google may periodically refresh the registration ID, so you should design your Android application with the understanding that the com.google.android.c2dm.intent.REGISTRATION intent may be called multiple times. Your Android application needs to be able to respond accordingly. So, Google automatically sends you this broadcast, when it renews the ID. You might not necessarily send check the emptyness of the ID. When Google changes the ID, then also it won't be empty, right? So if you want to handle the renewal/refreshing of the ID then you may do the

You route for /register should look like this: app.get("/register", function (req, res) { res.sendfile(__dirname + "/register.html"); }); Currently you have put both the login and the register view on "/", but only the first will work.

You must NOT comment out the rules() function. In it, you MUST set the attributes to safe, to allow Yii to copy the fields from the form to model: public function rules() { return array( array('username, password, user_sex, user_qq, user_hobby, user_xueli, user_introduce, user_email, user_tel', 'safe'), ); } See also: http://www.yiiframework.com/wiki/161/understanding-safe-validation-rules/

The information you need is in the traceback you have provided, In template /Users/Studio/Desktop/pod/t1/tut/tut/templates/base.html, error at line 16 Reverse for 'index' with arguments '()' and keyword arguments '{}' not found. In your base.html template, on line 16, you are using the url tag to link to the view named 'index'. 16 <a href="{% url 'index' %}">{% trans "Home" %}</a> | However, there is no url pattern named index in your url patterns. Therefore the reverse fails, and raises a NoReverseMatch exception. You can fix this by creating an index view in your tut.views module, and adding it to your url patterns. url(r'^$', 'tut.views.index', name='index'), Alternatively, you can remove the {% url 'index' %} from your template until you add an index vi

If you have copy something to clipboard and paste that in vim, you can use "+p. + is a quoteplus, which means CLIPBOARD documented X selection. :help quoteplus for more information. If you want to copy something in vim to clipboard and paste the content in the other place by Ctrl+v, you can do "+yy, this will copy the current line to clipboard. more information about vim register: :help registers :help quotestar

var userID = System.Web.Security.Membership.GetUser().ProviderUserKey; Using the WebSecurity and System.Web.Security items will only work on subsequent request because you have not sent the auth cookie back to the client yet (this is where it pulls its data from). Given that, you should not even have to send the user Id of the user in the redirect URL...they are logged in and you can just get it at the controller/action that you are going to. By grabbing the userId from the auth ticket, you now do not have to check if the user Id passed in the URL is actually the user that is currently logged in. Example: Login Method [HttpPost] [AllowAnonymous] [ValidateAntiForgeryToken] public ActionResult Register(RegisterModel model) { if (!ModelState.IsValid)

Try registerReceiver(yourReceiver, new IntentFilter("android.intent.action.BATTERY_CHANGED")); You might will need to add the <uses-permission android:name="android.permission.BROADCAST_STICKY"/> in your Manifest file

First of all, you must use an AsyncTask, since the register method is blocking, and can't be called by the main thread. You cab save the registration id in shared preferences and access it from anywhere. See the deno code at the GCM programmers guide. As for using the send method, you should only use it for device to cloud messages, which are messages from your app to your server. For such messages to reach your server your server must establish a XMPP connection with the GCM server. For the simpler cloud to device messaging, you can send messages from your server to your app via the HTTP API .

In your database, you are storing the password field with md5 encryption. So, while checking username and password in your login and checkuser function, you nee to check password as md5($password). Also, I wonder why you have kept the form name and submit button name same.

I think you are overenginnering, try: $LocalOCXPath = "C:WindowsSysWOW64dxapi.ocx" Invoke-Command -ComputerName $ComputerName -ScriptBlock { & 'regsvr32.exe' $LocalOCXPath }

the issue is related to the todo tag. Every time you get that tag inside your startElement you override the current value of data: remove it from the startElement and instantiate it at declaration time public static XMLGettersSetters data = new XMLGettersSetters();

This question is kind of tricky. As far as I know, the way you compile will have impact on the result. I am not sure if this is what you need but if you don't use inline assembly, you can control it. You write your code in a separate .s file, and compile with optimization like -O3, gcc will not push and protect nonvolatile registers. I don't use inline assembly myself so I am not clear with that part. You can test it yourself :D BTW: I think if you write .asm file and use nasm to compile it and link the object with gcc, same thing would happen. With optimization, I don't think gcc will do the push/pop automatically. Let me know if there are something wrong in my reply. Thanks. Good luck xiangpisaiMM

Here's what you have to do : Write a class (in your library project) that overrides GCMBroadcastReceiver : package com.test.pushlibrary; import android.content.Context; import com.google.android.gcm.GCMBroadcastReceiver; public class PushLibraryBroadcastReceiver extends GCMBroadcastReceiver { /** * Gets the class name of the intent service that will handle GCM messages. */ @Override protected String getGCMIntentServiceClassName(Context context) { return "com.test.pushlibrary.GCMIntentService"; } } Change your manifest to refer to the new receiver : <receiver android:name="com.test.pushlibrary.PushLibraryBroadcastReceiver" ... The reason that your original code didn't work is that the default implementation of getGCMIntentS

The compare instruction produces enough information to determine all the ordering information—less than, equal to, or greater than. The branch instruction chooses which conditions to branch on. Change BLO to BHI. Note: You did not specify the architecture or assembly language, so I am partially guessing about BHI. You should check the documentation. Various architectures and assembly languages have variants for slightly different kinds of branches. For example, BHI may be for branching if the comparison shows one unsigned value is higher than another unsigned value, while BGT may be for branch if the comparison shows one signed value is greater than than another signed value.

You have not understand the android concept at all. There is always only one Activity at once visible. Therefore your code will not work. You can not instantiate a Activity by calling new Activity_X(); The Android OS is responsible to start / instantiate an Activity, and an Activity has its lifecycle (onCreate(), onResume(), onPause() onDestroy()) but you can not instantiate Activities directly like you would do, and as mentioned before, there is normally only one active Activity on screen (The only way you can have two activities active at the same time is, if you have a activity with transparent background on top of a normal activity). Read that: Android getting started
