Answer : For trigger of one pipeline from another azure official docs suggest this below solution. i.e. use pipeline triggers resources: pipelines: - pipeline: RELEASE_PIPELINE // any arbitrary name source: PIPELINE_NAME. // name of the pipeline shown on azure UI portal trigger: branches: include: - dummy_branch // name of branch on which pipeline need to trigger But actually what happens, is that it triggers two pipelines. Take an example, let suppose we have two pipelines A and B and we want to trigger B when A finishes. So in this scenario B runs 2 times, once when you do a commit (parallel with A) and second after A finishes. To avoid this two times pipeline run problem follow the below solution trigger: none // add this trigger value to none resources: pipelines: - pipeline: RELEASE_PIPELINE // any arbitrary name source: PIPELINE_NAME. // name of the pipeline shown on azure UI portal trigger: branches: includ...

Answer : No, Google Apps Script is its own programming language. There are a number of APIs for individual Google Apps, but they are not as comprehensive as what is provided via Google Apps Script. They're generally focused on providing access to the data, and might be suitable if you don't need to edit it. It is now possible to make requests to Google Apps Script from Python via the new Execution API, which uses a REST interface. Related blog post announcement. Learning some JS is still required. Python is amazing, and one of its most amazing qualities is being able to serve as a "glue" of sorts between different modules of a system (regardless of language). My suggestion is to try and make an Adapter/Wrapper around the Javascript commands you will need from Google App Script, exposing pure python functions to the rest of your program so it makes it easier on you. In the end, you will still require to learn some Javascript so... get going.

Answer : An HTTP GET request can't contain data to be posted to the server. However, you can add a query string to the request. angular.http provides an option for it called params . $http({ url: user.details_path, method: "GET", params: {user_id: user.id} }); See: http://docs.angularjs.org/api/ng. http#get and https://docs.angularjs.org/api/ng/service/ http#usage (shows the params param) You can pass params directly to $http.get() The following works fine $http.get(user.details_path, { params: { user_id: user.id } }); Starting from AngularJS v1.4.8 , you can use get(url, config) as follows: var data = { user_id:user.id }; var config = { params: data, headers : {'Accept' : 'application/json'} }; $http.get(user.details_path, config).then(function(response) { // process response here.. }, function(response) { });

Answer : Absolutely! You can either: download a ready made one - like kWS - Android Web Server or write your own - here's some code to integrate in to your project or just use as is. The book Pro Android Python with SL4A comes with some free downloadable source code, you can find it on that official site. In the source code samples there are examples of basic httpserver, and basic ftpserver. Both of those will work on Android devices, I imagine it is also possible to make a more advanced webserver using python, or perhaps even re-purpose one that is already in existence. There are actually several apps on the Google Play Store. A few of them even have PHP. My personal favorite is Servers Ultimate.

Answer : From within rails you can create a configuration object and obtain the necessary information from it: config = Rails.configuration.database_configuration host = config[Rails.env]["host"] database = config[Rails.env]["database"] username = config[Rails.env]["username"] password = config[Rails.env]["password"] See the documentation for Rails::Configuration for details. This just uses YAML::load to load the configuration from the database configuration file ( database.yml ) which you can use yourself to get the information from outside the rails environment: require 'YAML' info = YAML::load(IO.read("database.yml")) print info["production"]["host"] print info["production"]["database"] ... Bryan's answer in the comment above deserves a little more exposure: >> Rails.configuration.database_configuration[Rails.env] => {"encoding"=>"unico...

Answer : You should have a negligible performance impact with most SSDs. Especially with the latest Intel CPUs that can do hardware AES way faster than a drive (any drive) can read or write. My MacBook Pro pushes over 900 megabytes per second with AES according to the TrueCrypt benchmark, and that's a laptop. On my desktop I use 4 Samsung SSDs in RAID0 and I have BitLocker turned on. TrueCrypt on this same machine reports over 5GB/sec for AES. (Two 6-core Xeons...) That said, the SandForce SSD controller is said to do some internal compression/dedupe (which was proven via benchmarks that used large compressed files that it could not "optimize"). Obviously this is not going to work at all with BitLocker where every encrypted sector will be completely unique and uncompressible. So if you're planning on using an SSD, don't get a SandForce one - or if you do, make sure you can return it if you find that performance really degrades after you turn BitLocker on. ...

Answer : I looked into it and the smallest possible transparent GIF image, encoded as a data-uri, was this: data:image/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw== which is what I'm using now. If you need a transparent image 1x1 pixel, just set this data uri as src default attribute (keep the /// parts, it encodes byte 255, not a comment). data:image/gif;base64,R0lGODlhAQABAIAAAP///wAAACH5BAEAAAAALAAAAAABAAEAAAICRAEAOw== This is instead a base64 encoding for an image 1x1 white. data:image/gif;base64,R0lGODlhAQABAIAAAP7//wAAACH5BAAAAAAALAAAAAABAAEAAAICRAEAOw== Otherwise you could set data:null and save ~60 extra bytes for each image. The smallest I've ever seen data:image/gif;base64,R0lGODlhAQABAAAAACw= update: This seems broken and doesn't work anymore as reported by @bryc, please use the other answers.

Answer : This is the hardware serial number. To access it on Android Q (>= SDK 29) android.Manifest.permission.READ_PRIVILEGED_PHONE_STATE is required. Only system apps can require this permission. If the calling package is the device or profile owner then the READ_PHONE_STATE permission suffices. Android 8 and later (>= SDK 26) use android.os.Build.getSerial() which requires the dangerous permission READ_PHONE_STATE. Using android.os.Build.SERIAL returns android.os.Build.UNKNOWN. Android 7.1 and earlier (<= SDK 25) and earlier android.os.Build.SERIAL does return a valid serial. It's unique for any device. If you are looking for possibilities on how to get/use a unique device id you should read here. For a solution involving reflection without requiring a permission see this answer. Up to Android 7.1 (SDK 25) Until Android 7.1 you will get it with: Build.SERIAL From Android 8 (SDK 26) On Android 8 (SDK 26) and above, this field will return UN...

Answer : aWallet specifically: don't use it. The creator obviously doesn't know what they are doing. I'll just pick out one concern (there are several that will probably be more obvious to People Smarter Than Me): it could encrypt your database in ECB mode (sometimes, but not always). ECB mode is notably not secure because the same plaintext always encrypts to the same cypher text. Therefore, ECB mode "does not hide data patterns well...it doesn't provide serious message confidentiality, and it is not recommended for use in cryptographic protocols at all". Password managers in general: use one. But pick a well-known one with good reputation like 1Password, LastPass, KeePass, Dashlane, etc. Or at least use one created or recommended by a well-known security company or security researcher if you don't know where else to look. A good password manager with competent encryption ( not aWallet apparently) is perfectly safe to keep on cloud storage, provid...

Answer : Updated Answer: If you are using Babel 7.4.0 or newer, then @babel/polyfill has been deprecated. Instead, you will want to use the following at the top of your main js file (likely index.js or similar): import "core-js/stable"; import "regenerator-runtime/runtime"; Install these packages either with npm: npm install --save core-js npm install --save regenerator-runtime or with yarn: yarn add core-js yarn add regenerator-runtime Original Answer: I just encountered this problem and came across the following solution: In package.json I had @babel/polyfill as a dependency. However, in my index.js (My main js file) I had neglected to place the following line at the the top: import '@babel/polyfill' Once I imported it, everything worked fine. I did not need to install babel-runtime as other answers are suggesting. There is already a very good answer here (originally posted on the Babel6 question) which I will just translate to Yarn. ...

Answer : Fist of all: I believe that you are mixing up the MVC pattern and n-tier-based design principles. Using an MVC approach does not mean that you shouldn't layer your application. It might help if you see MVC more like an extension of the presentation layer. If you put non-presentation code inside the MVC pattern you might very soon end up in a complicated design. Therefore I would suggest that you put your business logic into a separate business layer. Just have a look at this: Wikipedia article about multitier architecture It says: Today, MVC and similar model-view-presenter (MVP) are Separation of Concerns design patterns that apply exclusively to the presentation layer of a larger system. Anyway ... when talking about an enterprise web application the calls from the UI to the business logic layer should be placed inside the (presentation) controller. That is because the controller actually handles the calls to a specific resource, queries the data by...

Answer : In your second image, the floating disconnected vertex is throwing off your total. Euler's Theorem only applies to connected graphs -- otherwise you could arbitrarily add as many isolated vertices as you want and make F − E + V F-E+V F − E + V come out to any arbitrary whole number greater than or equal to 2 2 2 . The last face is the entire plane that isn’t in the other faces you mentioned, which they called the outer, infinitely large region. In the case of a single point, it is the entire plane. A face can be thought of as a region of space such that you ca go anywhere in the region without having to cross over a line. Also, Euler's Theorem only applies to connected graphs. As an example, here is a planar graph representing a cube. You'll notice that the left image tells you to remove the bottom, but it should say that the area that isn’t labeled "side" or "top" is the bottom of the cube.
