It's not that my search turned up nothing, it's that my search turned up so many different solutions -none of which have worked. Anyways, I am simply unable to push, pull, or fetch from my Heroku repository from my Mac. Every attempt gives me (as if it's mocking me) the following error: 'Permission denied (publickey). fatal: Could not read from remote repository.' I've tried (and re-tried) to fix it in many different ways. As I've

What's the best way to do that? 回答1: Update: For python 3.6+ you probably don't need anything special due to the new dict implementation (although considered CPython implementation detail for now). I like @James' solution for its simplicity. However, it changes the default global yaml.Loader class, which can lead to troublesome side effects. Especially,

In the process(key,value) method I use context.forward(key,value) to send the keys and values that I need. For debugging purposes I also print those. I have a KStream mergedStream that results from a join of two other streams. I want to apply the processor to the records of that stream. I achieve this with : mergedStream.process(myprocessor,"stateStoreName") When I start this program, I can see the proper values to be printed to my console.

E.g., say I have a struct struct Address:Codable { var street:String var zip:String var city:String var state:String } I can encode this to JSON. let address = Address(street: "Apple Bay Street", zip: "94608", city: "Emeryville", state: "California") if let encoded = try? encoder.encode(address) { if let json = String(data: encoded, encoding: .utf8) { // Print JSON String print(json) // JSON string is { "state":

Consequently, I want to remove the old SSH key directly on the server and upload a new one. I tried the following command without success: $> ssh-add -D Is there a way to completely remove a SSH key? 回答1: Note that there is at least two bug report for ssh-add -d/-D not removing keys: " Debian Bug report #472477: ssh-add -D does not remove SSH key from gnome-keyring-daemon memory " " Ubuntu: ssh-add

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效，请关闭广告屏蔽插件后再试): 由 翻译 强力驱动 问题: I have several database tables that just contain a single column and very few rows, often just an ID of something defined in another system. These tables are then referenced with foreign keys from other tables. For example one table contains country codes (SE, DK, US etc). All values are always unique natural keys and they are used as primary keys in other (legacy) systems. It seems really unnecessary to introduce a new surrogate key to these tables, or? In general, what are the exceptional cases when surrogate keys shouldn't be

Just use: heroku keys:add To clear all your previous keys do : heroku keys
