37,562,195 | 0 | <p>For logical reasons, tables are filled row by row in iText:</p> <p><a href="https://i.stack.imgur.com/SXI4A.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/SXI4A.png" alt="enter image description here"></a></p> <p>If you want to change the order, you need to do this yourself by creating a data matrix first. One way to do this, is by creating a two-dimensional array (there are other ways, but I'm using an array for the sake of simplicity).</p> <p>The <a href="http://developers.itextpdf.com/examples/tables/render-data-table#1834-rowcolumnorder.java" rel="nofollow noreferrer">RowColumnOrder</a> example shows how it's done.</p> <p>This is the normal behavior:</p> <pre><code>document.add(new Paragraph("By design tables are filled row by row:")); PdfPTable table = new PdfPTable(5); table.setSpacingBefore(10); table.setSpacingAfter(10); for (int i = 1; i <= 15; i++) { table.addCell("cell " + i); } document.add(table); </code></pre> <p>You want to change this behavior, which means that you have to create a matrix in which you change the order rows and columns are filled:</p> <pre><code>String[][] array = new String[3][]; int column = 0; int row = 0; for (int i = 1; i <= 15; i++) { if (column == 0) { array[row] = new String[5]; } array[row++][column] = "cell " + i; if (row == 3) { column++; row = 0; } } </code></pre> <p>As you can see, there is no iText code involved. I have 15 cells to add in a table with 5 columns and 3 rows. To achieve this, I create a <code>String[3][5]</code> array of which I fill every row of a column, then switch to the next column when the current column is full. Once I have the two-dimensional matrix, I can use it to fill a <code>PdfPTable</code>:</p> <pre><code>table = new PdfPTable(5); table.setSpacingBefore(10); for (String[] r : array) { for (String c : r) { table.addCell(c); } } document.add(table); </code></pre> <p>As you can see, the second table in <a href="http://gitlab.itextsupport.com/itext/sandbox/raw/master/cmpfiles/tables/cmp_row_column_order.pdf" rel="nofollow noreferrer">row_column_order.pdf</a> gives you the result you want.</p> |
7,992,624 | 0 | <p>I would re-think your storyboard layout here a bit. The title screen and login screens are essentially just modal views on top of the main part of your app, the <code>UITabBarController</code>. I would have the <code>UITabBarController</code> be the initial view controller in the storyboard and then conditionally present the title view/login screen modally as soon as the application finishes launching. </p> <p>Now with this design, showing the login screen is as simple as performing any modal segue. You may want to think about using delegation from the settings view controller to notify the presenting view controller that the user logged out and that the login view controller should be presented.</p> |

25,167,304 | 0 | <p><code>char</code> isn’t special in this regard (besides its implementation-defined signedness), all conversions to signed types usually exhibit this “cyclic nature”. However, there are undefined and implementation-defined aspects of signed overflow, so be careful when doing such things.</p> <p>What happens here:</p> <p>In the expression</p> <pre><code>c=c+10 </code></pre> <p>the operands of <code>+</code> are subject to the <em>usual arithmetic conversions</em>. They include <em>integer promotion</em>, which converts all values to <code>int</code> if all values of their type can be represented as an <code>int</code>. This means, the left operand of <code>+</code> (<code>c</code>) is converted to an <code>int</code> (an <code>int</code> can hold every <code>char</code> value<sup>1)</sup>). The result of the addition has type <code>int</code>. The assignment implicitly converts this value to a <code>char</code>, which happens to be signed on your platform. An (8-bit) signed <code>char</code> cannot hold the value 135 so it is converted in an implementation-defined way <sup>2)</sup>. For <a href="https://gcc.gnu.org/onlinedocs/gcc/Integers-implementation.html#Integers-implementation" rel="nofollow">gcc</a>:</p> <blockquote> <p>For conversion to a type of width <strong>N</strong>, the value is reduced modulo <strong>2<sup>N</sup></strong> to be within range of the type; no signal is raised.</p> </blockquote> <p>Your <code>char</code> has a width of <strong>8</strong>, <strong>2<sup>8</sup></strong> is <strong>256</strong>, and <strong>135 ☰ -121 mod 256</strong> (cf. e.g. <a href="https://en.wikipedia.org/wiki/Two's_complement" rel="nofollow">2’s complement on Wikipedia</a>).</p> <p>You didn’t say which compiler you use, but the behaviour should be the same for all compilers (there aren’t really any non-2’s-complement machines anymore and with 2’s complement, that’s the only reasonable signed conversion definition I can think of).</p> <p>Note, that this implementation-defined behaviour only applies to conversions, not to overflows in arbitrary expressions, so e.g.</p> <pre><code>int n = INT_MAX; n += 1; </code></pre> <p>is undefined behaviour and used for optimizations by some compilers (e.g. by optimizing such statements out), so such things should definitely be avoided.</p> <p>A third case (unrelated here, but for sake of completeness) are unsigned integer types: No overflow occurs (there are exceptions, however, e.g. bit-shifting by more than the width of the type), the result is always reduced modulo <strong>2<sup>N</sup></strong> for a type with precision <strong>N</strong>.</p> <p>Related:</p> <ul> <li><a href="http://stackoverflow.com/questions/24156897/a-simple-c-program-output-is-not-as-expected">A simple C program output is not as expected</a></li> <li><a href="http://stackoverflow.com/questions/4240748/allowing-signed-integer-overflows-in-c-c">Allowing signed integer overflows in C/C++</a></li> </ul> <hr> <p><sup>1</sup> At least for 8-bit <code>char</code>s, signed <code>char</code>s, or <code>int</code>s with higher precision than <code>char</code>, so virtually always.</p> <p><sup>2</sup> The C standard says (C99 and C11 (n1570) 6.3.1.3 p.3) “[…] either the result is implementation-defined or an implementation-defined signal is raised.” I don’t know of any implementation raising a signal in this case.

34,144,314 | 0 | how to have fread perform like read.delim <p>I've got a large tab-delimited data table that I am trying to read into R using the data.table package fread function.

My request time goes from ~0.125 sec to ~0.001 sec. Fantastic.</p> <p>I deploy the identical code to a remote machine running Apache/Mod_WSGI and my request time goes from ~0.155 sec (before I deployed the change) to ~.400 sec (post deployment).

I've tried using FileBasedCache with a location on tmpfs, but that also failed to improve performance.</p> <p>I've monitored the remote machine with top, and it shows no other processes and it has 6GB available memory, so basically Django should have full rein. I love Django, but it's incredibly slow, and so far I've never been able to get the caching framework to make any noticeable impact in a production environment.

746,730 | 0 | <p>Developing UI is time consuming and error-prone because it involves <a href="http://en.wikipedia.org/wiki/Design" rel="nofollow noreferrer">design</a>. Not just visual or sound design, but more importantly interaction design. A good API is always interaction model neutral, meaning it puts minimal constraints on actual workflow, localisation and info representation. The main driver behind this is encapsulation and code re-use.</p> <p>As a result it is impossible to extract enough information from API alone to construct a good user interface tailored to a specific case of API use. </p> <p>However there are UI generators that normally produce <a href="http://en.wikipedia.org/wiki/Create,_read,_update_and_delete" rel="nofollow noreferrer">CRUD</a> screens based on a given API. Needless to say that such generated UI's are not very well-suited for frequent users with demands for higher UI efficiency, nor are they particularly easy to learn in case of a larger system since they don't really communicate system image or interaction sequence well.</p> <p>It takes a lot of effort to create a good UI because it needs to be designed according to specific user needs and not because of some mundane API-UI conversion task that can be fully automated. </p> <p>To speed the process of building UI up and mitigate risks it is possible to suggest either involving UI professionals or learning more about the job yourself. Unfortunatelly, there is no shortcut or magic wand, so to speak that will produce a quality UI based entirely and only on an API without lots of additional info and analysis. </p> <p>Please also see an excellent question: "<a href="http://stackoverflow.com/questions/514083/why-is-good-ui-design-so-hard-for-some-developers">Why is good UI design so hard for some developers</a>?" that has some very insightful and valuable answers, specifically:</p> <ul> <li><p>Shameless plug for <a href="http://stackoverflow.com/questions/514083/why-is-good-ui-design-so-hard-for-some-developers/516204#516204">my own answer</a>.</p></li> <li><p><a href="http://stackoverflow.com/questions/514083/why-is-good-ui-design-so-hard-for-some-developers/537490#537490">Great answer</a> by Karl Fast.</p></li> </ul> |

15,339,179 | 0 | <p>I guess, at runtime, container method calls are just resolved in the private Empty class, which makes your code fail.

That's why your code fails.</p> <p>If Empty were internal, you would be able to manipulate its instances accross the whole assembly, (well, not really because Factory is private) making all dynamic calls allowed, and your code work.</p> |
