Why is my s3 hosted website that I set up SSL for via cloudfront only working sporadically?
So I have a static website hosted on s3. I set it up to work with AWS certificate manager, route 53, and cloud front so that the site can be accessed with https. It seems to be sort of working after a lot of fiddling but it then breaks super weirdly. For example I can go to the following no problem: www.myurl.com https://www.myurl.com/ https://myurl.com/ http://myurl.com/ Great! But then I click a link on this homepage to take me to another page named login.html but this ONLY works for a few of the above links. For...

Python: How to use splinter/browser?
How to get on the form. Form is to filled out. Thank you and will be sure to vote up and accept the answer! 1 AnswersAnswers 1 Browser has a method called: fill_form(field_values) It takes a dict parameter, with the field names, and the values, and it fills the form at once. So you'll use browser.fill_form(dict) instead of browser.fill(field, value) More info about Browser's API and its methods here : https://splinter.readthedocs.io/en/latest/api/driver-and-element-api.html ...
(SWI)Prolog: Order of sub-goals
I have two, slightly different, implementations of a predicate, unique_element/2, in Prolog. The predicate succeeds when given an element X and a list L, the element X appears only once in the list. Below are the implementations and the results: Implementation 1: %%% unique_element/2 unique_element(Elem, [Elem|T]) :- not(member(Elem, T)). unique_element(Elem, [H|T]) :- member(Elem, T), H\==Elem, unique_element(Elem, T), !. Results: ?- unique_element(X, [a, a, b, c, c, b]). false. ?- unique_element(X,...
DNA Matching in Prolog
I am attempting to learn basic Prolog. I have read some basic tutorials on the basic structures of lists, variables, and if/and logic. A project I am attempting to do to help learn some of this is to match DNA sequences. Essentially I want it to match reverse compliments of DNA sequences. Example outputs can be seen below: ?- dnamatch([t, t, a, c],[g, t, a, a]). true While it's most likely relatively simple, being newer to Prolog I am currently figuring it out. I started by defining basic matching rules for the...
Resume download after killing or putting on background the application
I have some issues when I want to resume a download operation. I am using Alamofire 4.4 and I made my tests on iOS 9 and 10. Here is my use cases: 1- A download operation is in progress, I cancel the request (resumeData is generated and saved) and then I put the application on background. After relaunching the application, I resume the download (using the resumeData) some times the download is being resumed and sometimes is being restarted. Is it a normal behaviour ? And are there any solution if not ? 2- A download operation...

Implementing an efficient graph data structure for maintaining cluster distances in the Rank-Order Clustering algorithm
I'm trying to implement the Rank-Order Clustering here is a link to the paper (which is a kind of agglomerative clustering) algorithm from scratch.

Make ToolBar look like Windows Vista/7 instead of classic
I want to make my application look more like a native app than a .NET app and I use .NET because of Visual Designer and C#. I've seen some native apps using a toolbar that looks very similar to Vista/7 menus. Check out the example: Some native apps like Notepad++, Codeblocks, etc. uses the same Vista/7 style for toolbars. How can I do the same in C#? I know P/Invoke, so, I need to know the methods to be used or an example. I...

why is blindly using df.copy() a bad idea to fix the SettingWithCopyWarning
There are countless questions about the dreaded SettingWithCopyWarning I've got a good handle on how it comes about. (Notice I said good, not great) It happens when a dataframe df is "attached" to another dataframe via an attribute stored in is_copy. Here's an example df = pd.DataFrame([[1]]) d1 = df[:] d1.is_copy <weakref at 0x1115a4188; to 'DataFrame' at 0x1119bb0f0> We can either set that attribute to None or d1 = d1.copy() I've seen devs like @Jeff and I can't remember who else, warn about doing that....
