"Schema for storing historical transaction data in Neo4J?",
"I have around 200 entities that have invested in a company over the last 30 years. I have been tracking how much money they contributed over time. My database will be in Neo4J.\n\nSo far on my graph I have (1) 200 nodes representing the 200 entities that have invested and (2) 1 node representing the single company they invested in.\n\nI see two options for me to represent the capital infusions:\n\n\nI explicitly create 1,500 nodes representing each of the initial capital infusion, capital increase, etc. The nodes captures information on changes in dollar amounts, etc. Then my graph is roughly this (e:Entity)-[:PROVIDES]->(f:Financing {amount: {value}, year: {2010}})-[:PROVIDES]->(t:Target). In some way, I find this much cleaner and easier for analysis down the road but this will be a larger graph and the PROVIDES relationships are not particularly insightful.\nI represent those 1,500 financing rounds much more directly as relationships between the 200 entities and the target company\n(e:Entity)-[:FINANCING {amount: {value}, year: {2010}}]->(t:Target). In that case, I'm a bit unsure about how to handle the analysis afterwards or whether it makes sense to have say 50 FINANCING relationships between Entity X and the target company.\n\n\nThe type of analysis I'd like to do would include (1) generating the target entity ownership say in year 2004, (2) generating the evolution over time of shareholding in the target company by entity X, etc.\n\nWhat would you recommend as a solution for the schema? I know Neo4J is schema-optional but I suspect this choice between nodes and relationships matters.\n\nMany thanks!\n\nCheers"

"Passing a javascript function to ReactJS.NET Server side",

I have a typeahead component which I use multiple times throughout my site. One of the properties it expects is a javascript filter function. \n\nI don't want to have to create a seperate component for each instance of the typeahead, but would like to pass in a javascript function as a property so that I can reuse the component throughout the site. \n\nFor example, to render a component on the server I would do the following. The second parameter is the properties argment\n\n\n @Html.React(\"Components.WorkSiteTypeahead\", new { filterFn = model.SomeFunction })\n\n\nNow as ReactJS.net expects native c# objects (string, array, list, etc), I don't see any straight forward way to pass in a Javascript function. Any ideas on how would I go about telling my MVC5 view to render my function not as a string?

"Programmatically adding a hyperlink to a bulleted list that IS NOT DisplayMode=Hyperlink",
"I have a ASP.NET bulleted list control that, until today, was created and used only for plain text. A new design request asks that I turn SOME of those items into hyperlinks. Therefore the bulleted list will ultimately need to contain some plain text items, and some hyperlinks. If I change it to DisplayMode=Hyperlink, even if I leave the value blank, the entries that should just be plain text still become clickable links.\n\nOne solution that I think I can make work, is to use a Literal control and use HTML (<a href...) on the lines that need to be links. That will entail a little bit of re-working some old code, so before I try that I really want to know if this is possible to do with the existing BulletedList. \n\n\n\nEDIT:\n\nI seriously couldn't find anything about this anywhere, and I generally consider myself a pretty good Googler. So for the one or two lost and confused souls who find themselves in the same scenario sometime in the next decade, here is my complete implementation of the excellent answer offered below:\n\nIn the page's code-behind:\n\nforeach (SupportLog x in ordered)\n{\n blschedule.Items.Add(new ListItem(x.Headline, \"http://mysite/Support/editsupportlog.aspx?SupportLogID=\" + x.SupportLogID));\n}\n\nblschedule.DataBind();\n\n\nNote the DataBind at the end --- this is necessary to fall into the DataBound event:\n\nprotected void blschedule_DataBound(object sender, EventArgs e)\n{\n foreach (ListItem x in blschedule.Items)\n {\n if (x.Value.Contains(\"http\")) //an item that should be a link is gonna have http in it, so check for that\n {\n x.Attributes.Add(\"data-url\", x.Value);\n }\n }\n}\n\n\nIn the .aspx page's head:\n\n<script src=\"<%# ResolveClientUrl(\"~/jquery/jquery141.js\") %>\" type=\"text/javascript\"></script>\n <script>\n\n $(document).ready(function () {\n\n $('#<%=blschedule.ClientID %> li').each(function () {\n var $this = $(this);\n var attr = $this.attr('data-url');\n\n if (typeof attr !== 'undefined' && attr !== false) {\n $this.html('<a href=\"' + $this.attr('data-url') + '\">' + $this.text() + '</a>');\n }\n });\n });\n\n </script>\n\n\nThe if statement is required to make sure to only turn the items that have the \"data-url\" attribute into links, and not turn ALL items into links."

"Object Oriented Method Bridge",
"Several resources in my system use the concept of Object Collections, based upon Java's Collections.\n\nThis Collection Class (abstract) provides basic functionality to another concrete class, called Lists, which allow to find Objects through Collection's Indexes.\n\nI'll use as example, my HTTP Headers Class to explain.\n\nI have, in its Constructor a instance of this Lists Class. Every HTTP Header Field is added in the Collection through Headers::addHeader() method.\n\nObviously, I have a getter method called getHeaders(), which return the Collection's Storage, not the Collection's Object.\n\nSo, if I need to list the Headers outside this class, I just have to call $obj -> getHeaders() and I have an ArrayObject with all Objects added.\n\nAlright!\n\nBut, recently, came up the necessity to use one of Lists methods, Lists::find(), which finds an Object without even know Object's name or its specific position in Collection's Storage.\n\nSince Lists object is in a private property, Headers::getHeaders() returns the Collection Storage and I don't want to violate the encapsulation, by making the property a public one, I can't access this method.\n\nEverything I code, besides the functionality, must be visually elegant, and create another getter method, let's say getHeadersLists() would produce an invocation like:\n\n$obj -> getHeadersLists() -> find( 'foo' );\n\n\nThis is ugly!\n\nSo, I quickly added a __call() in Headers Class and it worked fine:\n\n$obj -> find( 'foo' );\n\n\nBut someone I know (and he's very versed in Object Orientation theme) told me this is wrong.\n\nMy argument was purely focused on readability, and he counter-argued \"in Object Orientation, Magic Methods and Readability cannot coexist\".\n\nSo what? What should I do to create this \"bridge\" between these two classes, without use a _call() and preserving the Object Orientation's principles?\n\nI know, I could return the Collection Object in Headers::getHeaders() and use something like:\n\n$obj -> getHeaders() -> find();\n\n\nBut something I learned about Object Orientation is responsibility. The responsibility of this method, as its declaration said, it's to return all the Headers added and not an outside object."

"Javascript modules, passing jQuery when it may not be loaded",
"I'm learning the module pattern for javascript in order to tidy up my code and reduce the need for a long 'global' javascript file.\nAs a consequence of this, I have a top level 'namespace' module, and a utility module in the same file. The utility module has some functions that require jquery, and others that do not.\n\nOn lightweight pages that use no jQuery, I don't want to load the library (I have a very good reason for not doing so).\nThe problem arises when jQuery is passed as a parameter to the module as in the following:\n\nMODULE.vars = (function (variables,$) {\n variables.cdn = undefined; //global for clientside cdn\n variables.version = undefined; //global for clientside cdn version\n variables.isTouchScreen = undefined; //global for touchscreen status\n\n //Check if jquery exists, if so patch the jquery dependent functions\n if ($) {\n $(document).ready(function () {\n variables.isTouchScreen = $('html').is('.touch');\n });\n }\n\n return variables;\n\n}(MODULE.vars || {}, jQuery));\n\n\nThe code stops on pages that I don't load jquery, stating that jQuery is undefined - fair enough. If I change the last line to:\n\n}(MODULE.vars || {}, jQuery || false));\n\n\nthe code still complains that jQuery is undefined. I thought, perhaps erroneously, that if jQuery was undefined, it would be passed as undefined in this instance and instead take up the value false (which logic dictates wouldn't be necessary anyway).\n\nHow do I get around this problem when jQuery may or may not be present? I attempted to put the following at the top of the script:\n\nvar jQuery = jQuery || false;\n\n\nthinking that this would then take up the value of jQuery if it was loaded. It works in modern browsers with this, but IE8 complains as it gets set to false even if jQuery is being loaded first on a page.\n\nThe scripts are all loaded in the correct order in the html, jQuery first, then my module afterwards.\n\nWhen checking for the cause, IE8 returns $ as an object and jQuery as false. If i do not set the above line in the script, jQuery returns as the same object as $.\n\nSadly I have to cater for IE8 as well, so how do I get around this issue of the optional presence of jQuery?\n\nEdit: This is only a snippet of the module and there are other functions that depend on jquery, but simply won't get implemented if jquery is not available"

My question is: from the moment the game starts, which is the most efficient way (not just code level but to the database and server) to calculate the ranking for the players \"real time\" as their predictions regarding the actual outcome of the game.\n\nFor example:\n\nIf a Team1 vs Team2 plays,\nthe user U1 predicted that the game would end 0-0,\nU2 predicted the game would end 1-0,\nU3 predicted the game would would end 1-1.\n\nWhen starting the game, the U1 would be to first in the ranking because, if the match ends like this, his prediction would be correct, or at least the most accurate.\n\nThen the score switches to 1-0, and the user U1 would be the last of the ranking (because his prediction is not possible anymore), U2 would be the first and U3 second.\n\nIf the score changes to 1-1, U2 would go first, U3 would be second (because he guessed part of the result) and U3 last.\n\nI thought about creating a tree of possibilities with one level (0-0 first node, with 1-0 and 0-1 as child nodes) as you change the score, changes the Ranking \"temporarily\" and I would keep it in cache.\n\nOnce the game is over, I keep the latest Ranking in the database.\n\nThere is a more optimal way to solve this problem? \nIt has been proposed before and already solved? \nI'm using MySQL for database, PHP (Cake Php) for the server and a bunch of mobiles who ask for the ranking once in a while.\n\nSorry for my lame english =("

"Override HTML DOM element methods JS",
"Short question: \n\nHow may I override DOM built-in function as document.getElementById () or build my own method, in pure JS?\n\n\n\nExplanations:\n\nI am working on an API which uses attributes to locate divs in my HTML page. \n\nI can get the attributes of a div using this method:\n\nfor (var att, i = 0, atts = div.attributes, n = atts.length; i < n; i++) {\n att = atts[i];\n nodeName = att.nodeName; \n nodeValue = att.nodeValue;\n}\n\n\n\n\nThen, I need to use this code to check the attributes of a given HTML object. I built a method which checks the document's div's attributes:\n\ndocument.getElementByIdentifier = function (identifier) {\n for (var i = 0; i < this.children.length; i++) {\n for (var att, i = 0, atts = div.attributes, n = atts.length; i < n; i++) {\n att = atts[i];\n nodeName = att.nodeName; \n nodeValue = att.nodeValue;\n // Here I check the attributes\n }\n }\n} \n\n\nHowever, I can not call this function from an HTML Dom object (except, here, the document object). I do not find how to replace document by something like allHTMLElements in my method above. The goal is to have the same freedom of usage as document.getElementById for example.\n\nHow may I do that?\n\n\n\nNote: I am very surprised because the document.getElementById seems to be located into the document object. However, when I try to build my own method into this object, it does not work. Why?\n\n\n\nOther note: This is (at least for me) an HTML DOM object:var A = document.getElementById (\"C\");. Here the object A is an HTML Dom object calls: \"object\" by google chrome when I try console.log (typeof A);. \n\n\n\nOtherwise note:\n\nThis is an example of one of my divs:\n\n<script identifier=\"OAdgRzf\"></script>\n\n\n\n\nFinally note:\n\nUse document.querySelector is the way I am already using on my library. However, I now have to run updates and tests for elements which are called by the user. I built a function which uses document.querySelector and then runs tests but it is not very pretty.\n\n\n\nTell me a comment if you have some questions."

"keyboard emulator device behavior on ubuntu",
"I'm building a device driver of sorts that consumes data from a keyboard emulating device.\n\nThe device is a card swipe, so its behavior is as follows:\n\n\nUser walks up, swipes card\nI get a string of characters (key codes, really, including modifier keys for capital letters)\nI don't know how many characters I'm going to get\nI don't know when I'm getting something\n\n\nSince I don't know how many characters I'm going to get, blocking reads on the keyboard tty aren't useful - I'd end up blocking after the last character. What I'm doing is, in Ruby, using the IO module to perform async reads against the keyboard device, and using a timeout to determine that the end of data was reached. This works fine logically (even a user swiping his or her card fast will do so slower than the send rate between characters). \n\nThe issue is that sometimes, I lose data from the middle of the string. My hunch is that there's some sort of buffer overflow happening because I'm reading the data too slowly. Trying to confirm this, I inserted small waits in between each key process. Longer waits (20ms+) do exacerbate the problem. However, a wait of around 5ms actually makes it go away? The only explanation I can come up with is that the async read itself is expensive (because Ruby), and doing them without a rate limit is actually slower than doing them with a 5ms delay. \n\nDoes this sound rational? Are there other ideas on what this could be?\n\nThe ruby is actually JRuby 9000. The machine is Ubuntu LTS 16.\n\nEdit: here's a snippet of the relevant code\n\n private def read_swipe(buffer_size, card_reader_input, pause_between_reads, seconds_to_complete)\n limit = Time.now + seconds_to_complete.seconds\n swipe_data = ''\n begin\n start_time = Time.now\n sleep pause_between_reads\n batch = card_reader_input.read_nonblock(buffer_size)\n swipe_data << batch\n rescue IO::WaitReadable\n IO.select([card_reader_input], nil, nil, 0.5)\n retry unless limit < start_time\n end while start_time < limit\n swipe_data\n end\n\n\nwhere card_reader_input = File.new(event_handle, 'rb')"

"How can i get size of an array in the called function?",
"It's just a self-assessment question as a result of curiosity; so please cope with it. \n\nI know that in C we pass things by value. In case of arrays the scenario is different. We cannot pass them by their values and if we don't; a demotion from array type to pointer type will occur. We need to pass the value of the pointer to the first element of the array or pointer to the array itself. Yeah, this is what people call as array decay. As, the original type information of array is lost while passing we cannot obtain the size information of the passed array in the called routine unless we pass by reference. \n\nHave a look at the following code:\n\n#include <stdio.h>\n#include <stdlib.h>\n\nvoid cal(int (*b)[3]) \n{\n printf(\"%d\",sizeof(*b));\n}\n\nint main()\n{\n int a[3] = { 2,3,4 };\n cal( &a ); \n}\n\n\nOutput:\n\n12 \n\n\nOkay, we got what we want.\nBut what I concluded is that the number of elements in the array are always required when you declare a pointer to a non-variable array like this :\n\nint a[] = { 3, 4, 5 }; // declaring an array of size 3\nint (*p)[3]; // declaring a pointer to an array with length 3\np = &a ; // assignment\n\n\nSo, you are implicitly passing the length of the array to called function and there always exist a different way of doing it by passing an extra length argument to the called function in the case when you don't pass the reference of the array.\n\nP.S. You always need to pass the length whether you do in an explicit manner or in implicit one and it is just like hardcoding things.\n\nIs there exist an other techniques for having the size information of the passed array in the called function or I'm hitting right on the money?\nAnd, how will you deal with the dynamic ones'?"

"Migrate from SHA256 hashed passwords to BCRYPT in PHP7+MySQL",

Now I want to update the web application to use the more secure BCRYPT password_hash() however I don't want to email all registered users alerting them to change their password. So I was thinking on implementing BCRYPT on the sha256() hashed password this way:\n\nTo save the password I will sha256() hash the user's password:\n\n$hashed_password = password_hash(hash(\"sha256\", trim($_POST[\"password\"])), PASSWORD_BCRYPT);\n\n\nThen I will save the BCRYPT hashed password in the database.\n\nAnd to verify the user's password I would simply do this:\n\n$hashed_password = \"select hashed_password from users where email = '[email protected]'\";\n\nif(password_verify(hash(\"sha256\", trim($_POST[\"password\"])), $hashed_password))\n{\n echo \"Welcome\";\n}\nelse\n{\n echo \"Wrong Password!\";\n}\n\n\nThis way I will just update the user's password in the MYSQL database by looping each registered user, then I will retrieve the sha256() hashed password, and finally I will just re-save it after it has been BCRYPTed with password_hash():\n\n$new_password = password_hash($old_sha256_hashed_password, PASSWORD_BCRYPT);\n\n$mysql->save_user_password($new_password, $user_id);\n\n\nSo users will still be able to login with their old password.\n\nWhat do you think about this solution?\n\nIs it still safe even if I sha256() hash the password before BCRYPT it?"

"Change IME Option of Edittext in Recyclerview",
"I am working on a Learning app, it has a Tabview so I'm working with Fragments.\nThe last fragment has buttons on top to navigate through the multiple levels. Below that there is a Recyclerview which contains a Cardview with a Question on the left and an Edittext on the right to answer.\nCurrently the IME Option is actionSend and I want to not only skip to the next Edittext but also evaluate the Answer that was given. I achieved this already by implementing an OnClickListener but it's quite annoying having to click each Cardview in the Recyclerview to get Feedback, so I want to copy it to the setOnEditorActionListener function for the Editext. The problem I have is that I don't know how to get the position of the current Cardview item (to evaluate the givenAnswer with the corresponding item in the Questionlist) in the Recyclerview without actually clicking it just by changing the Editext.\nprivate RecyclerView myrecyclerview;\nprivate ArrayList<Question> QuestionList;\nprivate QuestionAdapter recyclerAdapter;\nprivate EditText givenAnswer;\n\npublic void ClickManager(final ArrayList<Question> list){\n //works perfectly when the item is clicked\n recyclerAdapter.setOnItemClickListener(new QuestionAdapter.OnItemClickListener() {\n @Override\n public void onItemClick(final int position) {\n View itemView = myrecyclerview.getLayoutManager().findViewByPosition(position);\n final EditText givenAnswer = itemView.findViewById(R.id.answer);\n ClickEvaluation(list,givenAnswer,position);\n }\n });\n\n givenAnswer.setOnEditorActionListener(new TextView.OnEditorActionListener() {\n @Override\n public boolean onEditorAction(TextView textView, int i, KeyEvent keyEvent) {\n boolean handled = false;\n if (i == EditorInfo.IME_ACTION_SEND){\n ClickEvaluation(list,givenAnswer,position); //can't access any position\n handled = true;\n }\n\n return handled;\n }\n });\n }\n\nThe evaluation function:\npublic void ClickEvaluation(final ArrayList<Question> list, EditText givenAnswer, int position){\n\n Question currenQuestion = list.get(position);\n if (currenQuestion.correct(givenAnswer.getText().toString())){\n currenQuestion.gaveCorrectAnswer();\n score += 1;\n current.setText(String.format("%d",score));\n }else{\n currenQuestion.showCorrectAnswer();\n }\n givenAnswer.setText("");\n recyclerAdapter.notifyItemChanged(position);\n}\n\nThanks a lot in advance!"

I tried to use channel 2 by adding a 2 to the prior line (I don't know if this makes sense) and it didn't work either ("Can't create RFCOMM TTY: Address already in use".)\nI also tried to use another device, hci1 instead of hci0, and it says: "Can't connect RFCOMM socket: Host is down". When I run the folowing:\nhcitool dev\n\nonly hci0 appears, so I don't know if I should create another device to be able to connect another sensor or how it is done.\nSo, anyone knows a way to make several Bluetooth serial connections, so that I can see the data several sensors are sending at the same time on different minicom windows?\nThanks."
