I've been studying TDD for a few years and read quite a few books but none that good to be honest. Can anyone recomend any good ones. I'm not interested in BDD but am keen on anything that tackles the many problems of mocking intrinsic MVC objects.

I'm getting ` Session: Error while trying to free lock for ci_session` show up in the error log a couple times a minute, sometimes, and every 15 minutes other times. Using Redis for sessions.

I have 30 functions like this void func1(int *var1, int *var2) { func2(var1, var2); } void func2(int *var1, int *var2) { func3(var1, var2); } void func3(int *var1, int *var2) { func4(var1, var2); } I do not need var3 until func15. Is there a way to fix this mistake without having to change all the function calls and headings? var3 needs to be remembered every time I get to func15. I only use var3 in func15 though so I really do not want to have to change all of my function calls and headings. It obviously can't be a local variable …

The facts: We are talking about a small company (5 persons) with many clients that making real money (we don't) . We provide our own software that has unique features against the e-commerce completion. The problem: the first glimpse of the problem arose around 2012 and made clear around 2014 with web sockets. Some clients didn't want a simple chat with their client but instead a full live eShop where they could negotiate the prices of a product or even start a discussion with a visitor. The solution would be implementing web sockets in to our framework and that worked …

How can I make this to continue until the user presses N? I've tried using while(1), while( option == 'y' || option == 'Y') but it kept giving an error for that, and if/else statements but no luck. So I decided to try a do while statement and same results, it seems it is working, but I don't know what I'm doing wrong. I even tried moving all the statements to different areas and still nothing. #include <stdio.h> #include <time.h> #include <stdlib.h> enum meme {YEE, KNUCKLES, DOGE, HARAMBE, BUTKUS}; int dankestmemes(void); // function prototype int main(void) { srand(time(NULL)); // randomize …

I am using `passport` in `laravel` for authenticating my users in APIs. I am able to authenticate different types of users from different tables and generating different token for them but the routes are not protected. For example. A user can access the routes like this Route::group(['middleware' => 'auth:api'], function () { Route::group(['prefix' => 'v1'], function () { Route::get('get-seller-list','API\v1\SellersController@index'); }); }); and A doctor can access the routes like Route::group(['middleware' => 'auth:sellers'], function () { Route::group(['prefix' => 'v1'], function () { Route::get('get-seller-detail','API\v1\TestController@getDetails'); }); }); but this `middleware` check doesn't seem to be working as I can access all the routes …

I need a form that accepts two operands and an operator from the user and then performs the requested operation. Specifications Before performing the calculation, the application should check that both operands are numeric and that the operator is one of the following: + add - subtract * multiply / divide It should also check that both operands are between 0 and 1,000,000 (non-inclusive). To perform this data validation, code IsPresent, IsDecimal, and IsValidData methods as described in chapter 7 of the book. In addition, code an IsOperator method that checks for a valid operator. Code a private method named …

I have a program that is meant to display the total, average, student name and letter grade for a student. I'm almost done writing it but I have no idea how to make it loop so it goes back to step 1 from step 4. Everything I've read on using "while" loops hasn't really been helpful to me with this particular application. import java.util.Scanner; public class Averages5 { public static void main(String[] args) { // variable declaration String name; int mark1, mark2, mark3 ; int grade = 0; int A, B, C, F; double average; // input Scanner input = …

This may sound wierd, or easy, I just don't have a statistics background. How do I alter the statistical value of an array of emmitted random numbers? I am completely capable of using ranges, or creating an algorithim, I just need pseudo code or a brief description to guide me through the process. This is not homework. This would mean I essentially generate randoms, and the final result has a statistical probability. Thanks!

if its possible please give me instructions Thank you in advance

Howdy All - I am just wondering if anyone has successfully converted a *massive* (subjectivity implied) COBOL application to another language. If so, into which language was your system converted and when was this done? What were the potholes you, no doubt, hit? Was the conversion far more expensive than anticipated? What hidden costs were exposed? Was there a performance gain/loss in the new language? Did anyone convert from COBOL to PL/SQL? to T-SQL? to Java? to C#.NET? Thanks, and have a great day!

If you have a counter that gets incremented through multiple functions, is it better to use a global counter or pointer counter? They both work just curious which is better and why.

Hi to all! I'm fairly new to using High availability group and i've been having issues with storage space from my Logs drive from my primary server..

I have a table that contains some cubes with servers and active status (see attached image): note: CUBE1 is repeated intentionally. The idea is the same cube is getting synced from the same server 1 as a data source (process_server) onto different target servers (query_server; say server2 is in region A and server 3 is in region B). The way the environment is set up is both servers have to be active/active status (meaning TRUE) except for some additional test cases, i am setting to false sometimes one or the other. I have the following script now calling the cube …

I want to protect my site from hacking. Currently I know about XSS and SQL injection. Do I need to use mysqli instead of mysql? And why? When should I use `htmlentities()` and `striptags()`? I also don't want users to upload melicious files and since I accept file uploading, is it enough to check file type? If not what can I do to prevent this? My website runs on PHP, is there anything else I should worry about?
