"How to download multiple PDFs with curl in Terminal.app",
"In terminal.app I entered this line\n\ncurl -o http://print.nap.edu/pdf/0309065577/pdf_image/[1-319].pdf\n\nAnd it in Terminal it says:\n\ncurl: no URL specified!\n\nHow is this possible? I'm just trying to download a bunch of successively numbered PDF files from a web server. If I leave off the -o it just downloads a bunch of gibberish into the Terminal window but not as a file.

"Setting href target dynamically for fancybox?",

"How to make dataguard switchover seamlessly",
"In my Dataguard configuration on a 12c environment, when I perform a switchover from primary (foo) to standby (bar) and then try to sqlplus in with user@foo, I receive the \"ORA-011033: ORACLE initialization or shutdown in progress\" error instead of being able to connect to the new primary(bar).\n\nNow, I know that this is because the connection is still pointing to the foo address instead of the bar address, and according to many articles, you need to create a new \"virtual\" service to handle the different connections, as well as a trigger to stop/start this service after a rolechange. \n\nI did this and with the service_names parameter set to this new \"virtual\" service, a switchover will work and can also switch back but when trying to sqlplus with user@foo it throws ORA-011033. The trigger is useless and the service continues to run on both foo and bar because it seems that having that parameter set overrides whatever the trigger tries to do. \n\nNow if I don't define that parameter, my switchover works fine, and the triggers do their job, and when I sqlplus user@foo, it will correctly redirect me to the bar address. However, when I try to switchover back to foo, I receive the following in the DG alert log:\n\nRedo transport problem detected: redo transport to database foo has the following error:\nORA-16047: DGID mismatch between destination setting and target database\n08/05/2016 16:01:02 \nInitialization of connection failed. \nExpected destination db_unique_name is foo.\nDatabase actually reached is bar \nFailed to send message to site foo.

"Encode a byte array with an alphabet, output should look randomly distributed",
"I'm encoding binary data b1, b2, ... bn using an alphabet. But since the binary representations of the bs are more or less sequential, a simple mapping of bits to chars results in very similar strings. Example:\n\nencode(b1) => \"QXpB4IBsu0\"\nencode(b2) => \"QXpB36Bsu0\"\n...\n\n\nI'm looking for ways to make the output more \"random\", meaning more difficult to guess the input b when looking at the output string.\n\nSome requirements:\n\n\nFor differenent bs, the output strings must be different. Encoding the same b multiple times does not necessarily have to result in the same output. As long as there are no collisions between the output strings of different input bs, everything is fine.\nIf it is of any importance: each b is around ~50-60 bits. The alphabet contains 64 characters.\nThe encoding function should not produce larger output strings than the ones you get by just using a simple mapping from the bits of bs to chars of the alphabet (given the values above, this means ~10 characters for each b). So just using a hash function like SHA is not an option.\n\n\nPossible solutions for this problem don't need to be \"cryptographically secure\". If someone invests enough time and effort to reconstruct the binary data, then so be it. But the goal is to make it as difficult as possible. It maybe helps that a decode function is not needed anyway.\n\nWhat I am doing at the moment:\n\n\ntake the next 4 bits from the binary data, let's say xxxx\nprepend 2 random bits r to get rrxxxx\nlookup the corresponding char in the alphabet: val char = alphabet[rrxxxx] and add it to the result (this works because the alphabet's size is 64)\ncontinue with step 1\n\n\nThis appraoch adds some noise to the output string, however, the size of the string is increased by 50% due to the random bits. I could add more noise by adding more random bits (rrrxxx or even rrrrxx), but the output would get larger and larger. One of the requirements I mentioned above is not to increase the size of the output string. Currently I'm only using this approach because I have no better idea.\n\nAs an alternative procedure, I thought about shuffling the bits of an input b before applying the alphabet. But since it must be guaranteed that different bs result in different strings, the shuffle function should use some kind of determinism (maybe a secret number as an argument) instead of being completely random. I wasn't able to come up wih such a function.\n\nI'm wondering if there is a better way, any hint is appreciated."

It's a relatively stupid device that mostly contains a DSP or two that act as tuners and otherwise does very little processing of the signal.\n\nI was thinking that kernel drivers for the device and then a userland hardware abstraction layer that provided a standardized interface and abstracted away the details of exactly when the RDS data was received and dealt with error handling and all the other messy stuff. Is there already a userland layer like this? It would be nice to either avoid making it at all, or make our stuff plug-compatible with something that already exists so we could use other projects for the radio UI if we wanted."

The only way I can get it to work is by adding a Route::controller('pages', 'PagesController') to the routes file then modifying the find function to getFind but that just ends up with a url that looks like example.com/pages/find/ rather than the original url that might have been something along the line of example.com/about-us."

I want to build an app that detects when I'm moving but when I've stopped and walked a few feet away from where I stopped, I want it to send a notification.\n\nI know the sensors detect that I'm driving with a few seconds but I don't know if it detects that driving has stopped as quickly. I know that android has motion sensors APIs but I don't know which sensor to use and what sensor type is best for this type of movement detection.\n\nI also know I would have to use GPS Permissions or whatever but I was wondering if anyone knew more about how I can approach this. \"Approach\" is not the best word since it makes it look like I'm trying to get people to help me solve this problem but I don't know how to word it.\n\nAny help is appreciated."

We are said not to use if in it and to use switch_case instead. in this code, I'm asking the user to enter three integer values and after some math operation, the result is the delta that needs to be defined that if it is positive, negative or equal to 0 and then do the appropriate operation on it. like below:\n\nint opt=0,a,b,c,delta;\ndouble x1,x2,real,img;\nprintf(\"Enter the integer coefficients a, b and c respectively: \");\nscanf(\"%i%i%i\",&a,&b,&c);\ndelta = b*b - 4*a*c;\n\n\nnow to link the correct operation to delta's sign, I need to use switch_case like this:\n\nswitch(delta){\n case delta>0:\n x1=(-b+sqrt(delta))/(2*a);\n x2=(-b-sqrt(delta))/(2*a);\n printf(\"the roots of the quadratic equation you entered are x1=%.3lf & x2=%.3lf\",x1,x2);\n break;\n case 0:\n x1=(-b)/(2*a);\n printf(\"the roots of the quadratic equation you entered are the same and equal to x=%.3lf\",x1);\n break;\n case delta<0:\n real=(-b)/(2*a);\n img=sqrt(-delta)/(2*a);\n printf(\"the roots of the quadratic equation you entered is x1=%.3lf+i%.3lf & x2=%.3lf-i%.3lf\",real,img,real,img);\n break;\n default:\n printf(\"an error accured during operation\");\n}\n\n\nbut since the delta is not predfined and is being calculated during the execution of the code, the cases don't work and I face with the error \"case label does not reduce to an integer constant\"\nIs there any trick or regular way to use switch_case with such variables(not predefined)??"

The file is like this\n\nProduct_id, Product_quantity\n1,\n2,\n3,\n4,\n5,\n6,\n7,\n8,\n9,\n10,\n\n\nNow I have developed a module where it will get all those product quanity from the product id\nand write them on the csv file without changinging any names\n\nSo for that I have my code is like this\n\nClass GetProducts extends Module {\n public function __construct() {\n $this->name = 'getproducts';\n $this->tab = 'pricing_promotion';\n $this->version = '1.0.0';\n $this->author = 'NewUser';\n $this->need_instance = 0;\n $this->bootstrap = 'true';\n parent::__construct();\n $this->displayName = $this->l('Get Products');\n $this->description = $this->l('lorem ipsum');\n $this->confirmUninstall = $this->l('Are you sure you want to uninstall?');\n $this->ps_versions_compliancy = array('min' => '1.6', 'max' => _PS_VERSION_);\n }\n\n public function install() {\n $return = (parent::install() \n && $this->registerHook('header'));\n return $return; \n }\n\n public function uninstall() {\n if ( !parent::uninstall() )\n return false;\n return true; \n }\n\n public function hookHeader() {\n $this->getProductQuantity();\n }\n\n public function getcsvUpdate() {\n $file = \"http://localhost/projects/product.csv\";\n $csv = array_map(\"str_getcsv\", file($file,FILE_SKIP_EMPTY_LINES));\n $keys = array_shift($csv);\n print_r($keys); //getting csv headers\n\n $stock_array = array();\n if (($handle = fopen($file, \"r\")) !== FALSE) {\n fgetcsv($handle);\n\n while (($data = fgetcsv($handle, 1000, \",\")) !== FALSE) {\n $stock_array[] = $this->get_qty($data[0]);\n }\n fclose($handle);\n }\n\n foreach( $stock_array as $stock ) {\n print_r($stock); //getting quantity and product id in array\n }\n\n }\n\n public function get_qty($id_product) {\n $product = new Product();\n $product_data[] = $id_product;\n $product_data[] = $product->getQuantity($id_product);\n return $product_data;\n }\n\n}\n\n\nYou can see I have got the csv header and the array where I get the product id with its\nquantity. So can someone tell me how to write those values to the csv\nwithout deleting existing data in the csv? Any help and suggestions will be really\nappreciable."
