问题 My website is: https://testfnm11.blogspot.com which is based on the Blogger Dynamic Views “Mosaic” template. (I have set the template to display Desktop view on Mobile devices). Bug: Always, the first (latest) Post in the site doesn't load fully, it loads only about half the page. On my site, at the moment the first page is "Windows to my World". (However, if you close the page and open another page, and then re-open the first page, then the page does open fully). This is a bug not only in my

问题 I'm using Python 3.6 and Spyder (Anaconda). I have tried many things but nothing worked out. I don't know why this error is coming always to me while loading with pickle. filename = "allfeatures.txt" allfeatures = open(filename, 'r').read() with open(filename) as f: allfeatures = list(f) allconcat = np.vstack(list(allfeatures.values())) TypeError Traceback (most recent call last) AttributeError: 'list' object has no attribute 'values' 回答1: You need to open your file as a binary file: pickle

问题 I have a login page using a StackLayout for the content (username, password, login button). After the user clicks the login button, I want a "loading" block set in the absolute center of the page, on top of the existing StackLayout content. For some annoying reason, this is not straightforward. It seems like a simple, common thing to do - how is this done? 回答1: You used a right tag: AbsoluteLayout. var loadingView = new StackLayout { Padding = 6, Orientation = StackOrientation.Horizontal,

问题 I'm talking about an icon that is displayed on a tab during page loading. Chrome: Firefox (with TreeTab plugin): You get the idea. I want to make it seem like the page is loading, when it's already loaded. Some event fires is javascript and then the tab looks like it's being loaded. Is there a way to do that? One way I can think of is to replace a favicon with a spinner, but I'm not sure if it's possible to change on the fly and even if it is, it would be a hassle to make it cross-browser.

So far I only got the cache be renewed after a day, with the next code: private final LoadingCache<String, Long> cache = CacheBuilder.newBuilder() .refreshAfterWrite(1, TimeUnit.DAYS) .build(new CacheLoader<String, Long>() { public Long load(String key) { return getMyData("load", key); } } 回答1: Here's a code snipped that implements JB Nizeth's answer (Java 8):
