11,377,999 | 0 | <p>I see that pretty much all the different options have already been laid out in different answers, but instead of commenting on all to give you my impression on what I think you should do, I'll just create an answer myself.</p> <p>Just to be clear on how I understand how the system works: All users can have multiple belongings, but any belonging can only be help by one person.</p> <p>In this case, it makes the most sense to have a user_id in the belongings table that can tie a belonging to a person. Once a user_id is set, nobody else can claim it anymore.</p> <p>Now, as to the 'favorite' part, there are several things you can do. What truly is the best way to do it strongly depends on the queries you plan on running on it. Some consider adding a JOIN table, but honestly this is a lot of additional data that is rather pointless; there is likely going to be the exact amount of rows in it as the user table and by putting it in a separate table, there is a lot you can't do (for example, see how many people DON'T have a favorite). Likewise, a JOIN table would make no sense for the user_belonging relationship, as there is a 1:1 relationship between the belonging and the amount of people who can have it.<br /> So I believe there are two viable options: either add a field (/switch) in the belongings table to indicate of a user's belonging is his/ her favorite, or add a field to the user table to indicate which belonging is the user's favorite. I would personally think that the latter holds the most merit, but depending on the queries you run, it might make more sense to to the former. Overall, the biggest difference is whether you want to process things pre-insert or post-select; e.g. in the latter situation, you will have to run an independent query to figure out if the user already has a favorite (in the former case this won't be necessary as you would put a unique index on the field in the user table), whereas in a post-select situation you will have to do cross reference which of the selected belongings from the belonging table is the user's favorite.</p> <p>Please let me know if I explained myself clearly, or if you have any further questions.</p> |

36,071,391 | 0 | <p>I'm surprised you had to ask, since it's basic Javascript, really... </p> <p>Since <code>press</code> is invoked from <code>oToggleButton</code>, the <code>this</code> keyword now holds a reference to <code>oToggleButton</code>, and <strong>not</strong> the controller (hence why the <code>getView()</code> method fails). Search for 'this keyword in inner function' for more info.</p> <p>To solve this, simply add a reference to this outside the inner function:</p> <p><code>var that = this;</code></p> <p>and in your inner function, use the reference instead:</p> <p><code>that.getView().addStyleClass("sapUiSizeCompact");</code></p> |
5,270,408 | 0 | <p>Your WHERE clause contains only joins. There are no filters. This means your query needs to consider all the rows in at least one table. From this it follows that your query should execute a FULL TABLE SCAN of at least one of your tables, not an indexed read. A full table scan is the most efficient way of getting all the rows in a table. </p> <p>So don't fix the syntax of your INDEX hint, get rid of it.</p> <p>Next, figure out which table should drive your query. This is business logic. Probably your requirement is something like </p> <blockquote> <p>"Summarise BL_DETAILS and BL_FREIGHT for every row in BL_CONTAINERS."</p> </blockquote> <p>In which case you might think you need a full table scan of BL_CONTAINERS. But if BL_FREIGHT has more rows than BL_CONTAINERS and every BLF_REF_NO matches a BL_REF_NO (i.e. there is a foreign key on BL_FREIGHT.BLF_REF_NO referencing BL_CONTAINERS.BL_REF_NO) it would probably be better to drive from BL_FREIGHT.</p> <p>Note that this is true if you are only interested in BL_CONTAINERS which have matching BL_FREIGHT rows. But if you want to include containers which have not been used (i.e. they have no matching no BL_FREIGHT records) you need to use outer joins and drive off the BL_CONTAINERS table.</p> <p>These considerations get more complicated when you throw BL_DETAILS into the mix. Your report seems to be based around the BL_DETAILS categories (as Jeffrey observes it is hard for us to understand your query without aliases or describes). So perhaps BL_DETAILS is the right candidate for driving table.</p> <p>As you can see, tuning requires insight into the business logic and the details of the data model. You have that local knowledge, we do not.</p> <p>There are tools which can help you. Oracle has EXPLAIN PLAN which will show you how the database will execute the query. The query optimizer gets better with each release so it matters which version of the database you're using.

25,552,324 | 0 | <p>git prevents you from altering your working directory in a way that overwrites local changes (e.g. in case of a checkout).</p> <p>Since your checkout went smooth, it simply means that the local changes were not overwritten by it, so there's no need to worry. You're still in a consistent state.</p> <p>Were you switching to a new branch perhaps? Or maybe the local changes were newly added files?

40,517,894 | 0 | <p>I would recommend against following the push paradigm that is suggested above and switch to the pull paradigm.

In a server application, it could be that this code often throws an exception, causing files to not be closed (because you don't close them in a finally) and over time those open file handles add up. There are other issues in how you are doing it (like relying on the <code>available()</code> to determine the size of the byte array), but that should not affect your problem.</p> <p>Another possibility is that under *nix systems sockets consume the same resource as files, so it could be that you have too many sockets (above what the system is configured to allow) open, causing this code to be unable to execute.</p> |

The only requirements on this table are that it display data and allow the user to sort it by clicking the header row.

Instead, using Chrome's debugging tools it appears that the target element is actually part of the template script block, and not the element the user actually sees.</p> <p>The best work-around I've got right now is to lookup the element actually attached to the DOM by retrieving unique info from its clone in the template.</p> <p>Here's the composite view code (borrowed from one of Derick Bailey's sample Fiddle's):</p> <pre><code>// The grid view var GridView = Backbone.Marionette.CompositeView.extend({ tagName: "table", template: "#grid-template", itemView: GridRow, events: { 'click th': 'doSort' }, doSort: function(event) { var target = $(event.target); this.collection.sortByField(target.data('sortby')); target.parent('tr').find('.sort').removeAttr('class'); target.addClass('sort ' + this.collection.sortdir); debugger; // NOTE: no change to elements in the DOM. WTH? target = this.$('[data-sortby=' + target.data('sortby') + ']'); target.parent('tr').find('.sort').removeAttr('class'); target.addClass('sort ' + this.collection.sortdir); debugger; // NOTE: DOM updated. }, appendHtml: function(collectionView, itemView) { collectionView.$("tbody").append(itemView.el); } }); </code></pre> <p>The template is simple as well:</p> <pre><code><script id="grid-template" type="text/template"> <thead> <tr> <th data-sortby="username">Username</th> <th data-sortby="fullname">Full Name</th> </tr> </thead> <tbody></tbody> </script> </code></pre> <p>A fork of Derek's original demo Fiddle modified to demonstrate the problem can be found here: <a href="http://jsfiddle.net/ccamarat/9stvM/14/" rel="nofollow">http://jsfiddle.net/ccamarat/9stvM/14/</a></p> <p>I've meandered a bit. My question is, I appear to have a spawned a Zombie View of sorts; is this a jQuery/Backbone/Underscore bug, or am I simply going about this all wrong?</p> <p>** EDIT ** Here's the console output showing the different parent hierarchies of the two elements: </p> <pre><code>console.log(target, targetb): [<th data-sortby="username" class="sort asc">Username</th>] [<th data-sortby="username">Username</th>] console.log(target.parents(), targetb.parents()): [<tr>…</tr>, <thead>…</thead>] [<tr>…</tr>, <thead>…</thead>, <table>…</table>, <div id="grid">…</div>, <body>…</body>, <html>…</html>] console.log(target === targetb): false </code></pre> |

And much less reads (several times per hour). The most frequent query takes 2 edges depth tracing that I expect to return ~10-20 result nodes. I don't have experience with graph databases and want to work with gremlin to be able to switch to another graph database if needed. Now I consider 2 possibilities: neo4j and Titan.</p> <p>As I can see there is enough community, information and tools for Neo4j, so I'd prefer to start from it. Their capacity numbers should be enough for our needs (∼ 34 billion nodes, ∼ 34 billion edges). But I'm not sure which hardware requirements will I face in this case. Also I didn't see any parallelisation options for their queries.</p> <p>On the other hand Titan is built for horizontal scalability and has integrations with intensively parallel tools like spark. So I can expect that hardware requirements can scale in a linear way. But there is much less information/community/tools for Titan.</p> <p>I'll be glad to hear your suggestions</p> |

38,350,373 | 0 | <p>If I understand correctly, the behavior you want is to drop each of your columns market with class="col" into a row, when your media query for small screens comes into effect.</p> <p>First of all, Outlook will strip out all in-line styling (as you noticed using F12), so best to double that up using the equivalent html attributes for each of your elements. </p> <p>Secondly, max-width is not supported by Outlook (and Lotus Notes 8 & 8.5), so you will need to wrap each of your <code><table></code>s that are inside you 'col' columns into conditional code which creates a table with a set width to hold everything in, that targets IE and Microsoft Outlook. You will need to use something like:</p> <pre><code><!--[if (gte mso 9)|(IE)]> <table width="525" align="left" cellpadding="0" cellspacing="0" border="0"> <tr> <td> <![endif]--> <table style="table-layout: auto; background-color: white; padding-left: 10px; padding-right: 10px;" border="0" cellpadding="0" cellspacing="0" width="100%"> <tbody> <tr> <td style="padding-top: 15px;padding-right: 20px;padding-bottom: 0;padding-left: 20px;font-size: 26px;line-height: 30px;font-weight:400; font-family: Arial, sans-serif; color: #0056a6;" align="left"><img src="/resources/handlers/dcimage.ashx" style="height: auto; display: inline;" border="0">,</td> </tr> <tr> <td style="padding-top: 15px;padding-right: 20px;padding-bottom: 20px;padding-left: 20px; font-size: 14px; font-weight:normal; line-height: 14px; font-family: Arial, sans-serif; color: #2d353d;" align="left"> LOREM IPSUM </td> </tr> </tbody> </table> <!--[if (gte mso 9)|(IE)]> </td> </tr> </table> <![endif]--> </code></pre> <p>I would strongly recommend following this <a href="http://webdesign.tutsplus.com/articles/creating-a-simple-responsive-html-email--webdesign-12978" rel="nofollow">guide to build responsive emails that work on all major mail clients</a> for a more in-depth explanation of this, and also other very useful tricks for making email work even on Outlook :)</p> |

7,235,961 | 0 | <p>You can have multiple programs in a shader, but not the other way around.</p> <p>To make multiple combinations, the easiest way is to store each major chunk as a fragment with a named entry point, then include them from another program or combine them at runtime into a single program, calling them in the order you need. That can get messy though, when handling input and outputs.</p> <p>You can use multiple passes, with different effects and programs in each pass. That has some additional overhead, but can be easier to set up.</p> |

Dates are days since 1900 (a date of 1 is 01/01/1900), and times are fractions of a day (so 0.5 is 12 hours).</p> <p>Depending on what format you need the value to be in before you put it in a database, then you might just want to take the numeric value and multiple by 24 to get the hours and fractional hours, eg:</p> <pre><code>double time = cell.getNumericCellValue() * 24; int hours = (int)time; int minutes = (time - hours) * 60; </code></pre> <p>Alternately, if you want a string, then the DataFormatter class will happily format a value of 1.5 as HH:MM to 36:00</p> |

25,249,191 | 0 | For Each Row in Range - Incorrect Row Iteration <p>I'm creating a single-column index file from multi-row/-cell source data in Excel. I have two worksheets - a source and destination - in a single workbook. Iterating through each row (11 in dev, ~15,000 in prod) of the source worksheet the <code>For Each</code> loop I wrote should:</p> <ul> <li>Find the first empty cell in Column A of the destination worksheet</li> <li>Use <code>LastCell.Value =</code> to input a set value in that cell</li> <li>Use <code>LastCell.Offset(r, c).Value =</code> to pair a set value with a copied value from each cell in a single row of the source worksheet to the next destination cell down. There are eight to be copied and a ninth that is set</li> </ul> <p>The loop works perfectly <strong>once</strong>, then fails to iterate to the next row. Each subsequent loop shifts copied values up by one and leaves the set values, with blanks, in place. It does this once for each cell in the source row and only after that does it move on to the next row down.</p> <p>When I say set value I'm referring to what is in quotes, and copied values are those of the <code>Row.Offset</code>.</p> <p>The code is:</p> <pre><code>Sub Export_Index_File() Dim wb As Workbook Dim ws1 As Worksheet, ws2 As Worksheet Dim sr As Range Set wb = ActiveWorkbook Set ws1 = wb.Worksheets("Source Data") Set ws2 = wb.Worksheets("Index File") Set sr = ws1.Range("A2:H13") For Each Row In sr.Cells Set LastCell = ws2.Cells(ws2.Rows.Count, "A").End(xlUp).Offset(1) LastCell.Value = "Begin Doc" LastCell.Offset(1, 0).Value = "Account Number: " & Row.Offset(0, 0).Value LastCell.Offset(2, 0).Value = "Account Type: " & Row.Offset(0, 1).Value LastCell.Offset(3, 0).Value = "Date: " & Row.Offset(0, 2).Value LastCell.Offset(4, 0).Value = "Doc Type: " & Row.Offset(0, 3).Value LastCell.Offset(5, 0).Value = "File Path: " & Row.Offset(0, 4).Value LastCell.Offset(6, 0).Value = "Institution: " & Row.Offset(0, 5).Value LastCell.Offset(7, 0).Value = "Name: " & Row.Offset(0, 6).Value LastCell.Offset(8, 0).Value = "TIN: " & Row.Offset(0, 7).Value LastCell.Offset(9, 0).Value = "End Doc" Next Row End Sub </code></pre> <p>Here are two output examples. Successful on the left, unsuccessful on the right:</p> <pre><code>Begin Doc |Begin Doc Account Number: 123456 |Account Number: Checking Account Type: Checking |Account Type:01/01/2001 Date: 01/01/2001 |Date: Statement Doc Type: Statement |Doc Type: 123456.pdf File Path: 123456.pdf |File Path: 123 Institution: 123 |Institution: Jane Doe Name: Jane Doe |Name: 123-45-6789 TIN: 123-45-6789 |TIN: End Doc |End Doc </code></pre> <p>Notice the one-line shift up. To fix this, I changed the loop to read <code>For Each Row In sr.Rows</code> but received Type 13 Mismatch errors. </p> <p>I copied this code from a working spreadsheet before expanding it to include more rows. It is nearly identical to the working code. What am I doing wrong?</p> |
