"Best way to join 2 tables using hibernate",
"I have 2 hibernate entities/tables and need to combine information from both for use in a view. The tables are\n\nTable Client:\n clientId,\n firstName,\n lastName,\n phone,\n cellPhone\n\nTable Appointment:\n apptTime,\n clientId (and some other fields I don't need now)\n\n\nThere is a one-to-many relationship between client and Appointment, based on clientID. In regular SQL I'd just say something like:\n\nSelect \n client.clientId, \n appt.apptTime,\n client.firstName,\n client.lastName \nfrom \n Client client, \n Appointment app \nwhere \n client.clientId = appt.clientId\n\n\nand use the recordset that was returned.\n\nI'm not sure how to do this in Hibernate. Should I create a ClientAppt entity and then do something like the above select (modified somewhat for HQL)? \n\nNote, I thought of using SecondaryTable approach, but I think that requires a 1 to 1 relationship? I suppose I could map a one to many, but is there an alternative? This is a one time change and mapping a one to many relationship might be a bit expensive for something this small?\nWhat is the best approach?\nThanks"

"What alternatives are there to identifying mobile devices without using their IMEI, SerialID, etc.?",
"Recently I came across an old project for Nokia Asha with app tracking in it.\n\nFor every screen accessed by the user a Http request would be made to report to the analytics service and one of the parameters sent was the IMEI in the mobile device.\n\nAs far as I know, retrieving information like the IMEI on Windows Phone and iPhone is not permitted but on Android it's still an available function but requires the permission to read the state and identity of the phone which I've been told scare some users.\n\nFrom what I'm seeing, using this kind of information is being discouraged in which case what alternatives are being more encouraged to implement to identify a device when it comes to analytics services or similar?"

"Chrome extension and .click() loops using values from localStorage",
"I have made a Chrome extension to help using a small search engine in our company's intranet. That search engine is a very old webpage really convoluted, and it doesn't take parameters in the url. No chance that the original authors will assist: \n\n\nThe extension popup offers an input text box to type your query. Your\nquery is then saved in localStorage \nThere is a content script inserted in\nthe intranet page that reads the localStorage key and does a document.getElementById(\"textbox\").value = \"your query\"; and then does\ndocument.getElementById(\"textbox\").click();\n\n\nThe expected result is that your search is performed. And that's all. \n\nThe problem is that the click gets performed unlimited times in an infinite loop, and I cannot see why it's repeating. \n\nI would be grateful if you would be able to assist. This is my first Chrome extension and all what I have been learning about how to make them has been a great experience so far. \n\nThis is the relevant code:\n\nThe extension popup where you type your query\n\npopup.html\n\n<input type=\"search\" id=\"cotext\"><br>\n<input type=\"button\" value=\"Name Search\" id=\"cobutton\">\n\n\nThe attached js of the popup\n\npopup.js\n\nvar csearch = document.getElementById(\"cotext\");\nvar co = document.getElementById(\"cobutton\");\nco.addEventListener(\"click\", function() {\n localStorage[\"company\"] = csearch.value;\n window.open('url of intranet that has content script applied');\n});\n\n\nAnd now the background file to help with communication between parts:\n\nbackground.js\n\nchrome.extension.onRequest.addListener(function(request, sender, sendResponse) {\nsendResponse({data: localStorage[request.key]});\n});\n\n\nAnd finally the content script that is configured in the manifest to be injected on the url of that search engine. \n\nincomingsearch.js\n\nchrome.extension.sendRequest(\n{method: \"getLocalStorage\", key: \"company\"},\n function(response) {\n var str = response.data;\n if (document.getElementById(\"txtQSearch\").value === \"\") {\n document.getElementById(\"txtQSearch\").value = str;\n }\n document.getElementById(\"btnQSearch\").click();\n });\n\n\nSo as I mentioned before, the code works... not just once (as it should) but many many times. Do I really have an infinite loop somewhere? I don't see it... For the moment I have disabled .click() and I have put .focus() instead, but it's a workaround. I would really like to use .click() here. \n\nThanks in advance!"

For \nexample:\n\nvoid OnFileDownloaded() {\n ...\n ApplicationEvents::Instance()->FileDownloaded(fileId_);\n}\n\n\nBut this looks like a mess in a code, and nearly impossible to test. \n\nAlternative solution would be to create ApplicationEvent in main function and pass it to classes constructors as a parameter.\nTo avoid mess in a code, decorator or proxy pattern can be used. \n\nFor example: 'FileDownloader' and decorating class 'LoggingFileDownloader'.\nBut the structure of application will be more complicated, many classes will just pass pointer to ApplicationEvents through to other classes, and probably it's overkill in my case.\n\nWhich solution will be best?"

"Creating pagination links with search parameters",
"I want to know how to approach implementing pagination with user input as search parameters. I understand the basics of pagination without user input and have no trouble doing that, it's when user input comes in that it confuses me. I don't know how to make the page-number links use the correct query based on what has been searched.\n\nFor example the basic idea: \n\nHTML\n\n<input type=\"text\" name=\"id\" placeholder=\"ID\">\n<input type=\"text\" name=\"name\" placeholder=\"Name\">\n<button id=\"btn_search\">Search</button>\n\n<div id=\"search_results\"></div>\n\n\nJS\n\n$(\"#btn_search\").on('click', function() {\n $.ajax({\n url: 'process.php',\n type: 'POST',\n data: {id: $(\"input[name=id]\").val(), name: $(\"input[name=name]\").val()},\n success: function(result) {\n $(\"#search_results\").html(result);\n }\n });\n});\n\n\nPHP\n\n// Grab submitted search parameters and store in variable\n if (isset($_POST[\"id\"]) && !empty($_POST[\"id\"])) {\n $id = $_POST[\"id\"];\n } else {\n $id = null;\n }\n if (isset($_POST[\"name\"]) && !empty($_POST[\"name\"])) {\n $name = $_POST[\"name\"];\n } else {\n $name = null;\n }\n $count_query = \"SELECT COUNT(*) FROM users\";\n // Code here to get total row count for pagination\n $query = \"SELECT * FROM users WHERE id = ? AND name = ?\";\n $stmt = $connection->prepare($query);\n $stmt->bind_param('is', $id, $name);\n $stmt->execute();\n // Dump as table\n\n\nI'm thinking the right approach is something like this: \n\n<ul class=\"pagination\">\n <li><a href=\"paginate.php?id=<?php echo $id; ?>&name=<?php echo $name; ?>\"></a></li>\n <li><a href=\"paginate.php?id=<?php echo $id; ?>&name=<?php echo $name; ?>\"></a></li>\n</ul>\n\n\nAnd then include one more parameter for the page number via a for loop.\n\nIs it safe to do this with some client-side input validation? And do I have a valid approach?\n\nEDIT \n\nNaveed's answer was helpful so I'll mark it as answered. This article: https://jadendreamer.wordpress.com/2012/11/20/php-tutorial-searching-and-pagination/ helped me out a lot with understanding how to do this. It is old but explains everything well. I ended up using the tags to pass back the query parameters."

The loop has 8 nodes, 1st node being labelled 0, 2nd being 1, and so on. Slow is at index 0 and fast is at 1, then they never collide:\n\nslow fast \n0 1\n1 4\n2 7\n3 2\n4 5\n5 0\n6 3\n7 6\n0 1 # pattern seems to restart here\n\n\nThis example and the statement that the runners inside a loop will always collide are contradictory, as the fast runner can keep jumping over the slow runner.\n\nI haven't taken a course on algorithms yet so please try to explain what I have got wrong as simply as possible."

My question is, when the difference between k and n is too much, such as when k=O(n2)or O(n3), can we say that the complexity is O(n2) or O(n3)?

"How to trigger an event everytime a notification is pushed on my AWS SQS destination?",
"I am using AWS SQS for Amazon MWS Order APIs. Everytime someone orders from a seller account who has added me as his developer, Amazon will send the notification to my AWS SQS Application.I can pull the notifications from there. But for this, I will have to create a scheduler to pull the notifications. Can I use any other AWS as a listener just to trigger my own service everytime a notification is pushed on my destination by Amazon? Can I use Lambda functions for it? I am new to AWS so I know only I little about it."

"How to join on three different tables",
"I am trying to fill my table with Companynames, but they all come from another table (depending on type of company)\n\nSo, for example, i have a 'regardingobjectid' in my current table, which is equal to the 'id' from the table 'opportunity'. In this table 'opportunity' there is no companyname, only a 'parentaccountid' which refers to an 'Id' in the table 'account', in which the name is known.\n\nSo the regardingobjectid from my current table matches with an id in another table, from which I have to take another column to match with a column in ANOTHER table to get the name.\n\nDoes anyone have a clue on how to do it? I tried multiple left joins but I can't get it right.\n\nI use SQL Server.\n\nHere is a piece of my code from what I tried:\n\nSELECT\ne.regardingobjectid as CompanyId,\ncase\n when e.regardingobjectid_entitytype = 'account' then a.name\n when e.regardingobjectid_entitytype = 'lead' then l.companyname\n when e.regardingobjectid_entitytype = 'opportunity' then o.name\n when e.regardingobjectid_entitytype = 'incident' then a.name\n when e.regardingobjectid_entitytype = 'contact' then a.name\n when e.regardingobjectid_entitytype = 'salesorder' then a.name\nend as Companyname\nfrom emails e\n\nleft join opportunity o on e.regardingobjectid = o.id\nleft join account a on e.regardingobjectid = a.id\nleft join lead l on e.regardingobjectid = l.id\nleft join incident i on e.regardingobjectid = i.id\nleft join contact c on e.regardingobjectid = c.id\nleft join salesorder s on e.regardingobjectid = s.id\n\n\nThis fills my table for the categories account, lead and opportunity, but not for the categories incident, salesorder and contact.\n\nIn the tables opportunity, account, and lead are names. But, in the tables incident, contact and salesorder there are no names. The names from the salesorder, contact and incident labelled companies are in the account table.\n\nFor example, the CompanyId from this select statement is the same as 'id' from the table incident. In this table incident, there is an 'accountid' which corresponds to the 'id' in the table account, from which I want the name.\n\nI managed to get the name for 'incident', but now my names for account are gone…\nWhen i type my joins like this: \n\nleft join crm_systemuser u on p.owneridyominame = u.fullname\nleft join crm_incident i on i.id = p.regardingobjectid\nleft join crm_account a on a.id = i.blue10_accountid\nleft join crm_opportunity o on o.id = p.regardingobjectid\nleft join crm_account s on s.id = p.regardingobjectid\nleft join crm_lead l on l.id = p.regardingobjectid\n\n\nMy incidents, leads and opportunities fills with names. However, when I switch order:\n\n left join crm_account a on a.id = e.regardingobjectid\n left join crm_systemuser u on e.owneridyominame = u.fullname\n left join crm_incident i on i.id = e.regardingobjectid\n left join crm_account on a.id = i.blue10_accountid\n left join crm_opportunity o on o.id = e.regardingobjectid\n left join crm_lead l on l.id = e.regardingobjectid\n\n\nMy incidents are empty again but my accounts are filled with names…"
