由 坚强是说给别人听的谎言 提交于 2019-12-11 07:07:42
问题 I have a large *.Rdata file of size 15 Gb (15'284'533'248 Bytes) created in RStudio on a MacBook Pro with 8 Gb RAM, containing several lists of dataframes. Now I want to load() the file into RStudio on my PC with 32 Gb RAM, but only the RAM swells beyond all measure and at the end I get this: Error: cannot allocate vector of size 78 Kb The comic is, when I reload it on the Mac it works totally fine. What's going wrong? [Edit1] RStudio 1.0.136 on Mac, RStudio 1.1.383 on PC. Both R 3.4.2.

问题 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 7 years ago . I've got the following problem: after the user clicks on a thumbnail image, a bigger image is loaded with lazy loading and opens up. The code to load the bigger image is: <img width="663" height="845" class="big"

问题 What is the standard way of showing a loader icon before browser downloads all js files and loads react application. Can I do something like this without breaking anything? <div id="content" class="app"> Loading... </div> 回答1: Yes. Once your javascript has loaded, you can replace Loading... by rendering your react app into the same <div> render( <App />, document.getElementById('content') ); 回答2: One way of doing this using component life cycle methods. class App extends React.Component {

Showing a loading image while loading php script

由 余生长醉 提交于 2019-12-11 05:22:50
问题 Small (or big) problem once again I am using a simple html form, on submit action calls a php (mail) script.. now this script takes a little while to finish as there are some time limits in there before sending another mail.. I expected it to load a blank page, or at least display everything before loop.. but it didn't, instead it sort of "hangs" at the form stuck (although you can see the url of the script is loading in the browser bar) and once the script is finished it loads all the output

由 不打扰是莪最后的温柔 提交于 2019-12-11 04:18:34
问题 In my application, I have a UIImageView and a UIButton. The UIImageView has a UIPanGestureRecognizer, and can be dragged around the screen.

Android Out of Memory Error when loading images from resource

由 非 Y 不嫁゛ 提交于 2019-12-11 04:07:28
问题 I have a layout which I'm adding ImageViews (about 13) to at run time using a single thread. When I load more than 7 or 8 images (970px x 970px, 270kb) the application crashes displaying an out of memory error. Now when I load the same image rather than choosing 13 different images it displays fine. And also when I reduce the size of the images (16px x 16px, 770bytes) it displays fine. So does anyone know what the max memory allowed when loading images? What is the best way to get around this

Showing a CSS loading indicator while fetching data

由 杀马特。学长 韩版系。学妹 提交于 2019-12-11 02:38:11
问题 I have a indeterminate linear css loading indicator like the ones in material design. Every time I fetch data from a Redux's reducer, I show this indicator. The problem is that while the indicator shows up, it is not being animated. It looks like the whole pages freezes up until the reducer is populated with the data. Let's suppose I have my loading indicator visible and animated at all times. As soon as I fetch/request data into a reducer, the loading indicator stops animating. What do you

Endless Listview with current Async Task

由 纵饮孤独 提交于 2019-12-11 02:38:08
问题 I have had a good look at CWAC Endless adapter and a couple of others that do the same thing, but I cannot work out how to apply them to my current method of retrieving data, which populates 2 rows and a listview. Currently the data is retrieved via httpget in an ASync background task. The url is altered slightly to get each subsequent page (page=1.html, page=2.html etc). I would like page 2 to load and append to the end of page 1 when the end is reached - I guess it is possible using CWACs
