Automate Heroku CLI Login


Answer :

The Heroku CLI only uses your username and password to retrieve your API key, which it stores in your ~/.netrc file ($HOME\_netrc on Windows).

You can manually retrieve your API key and add it to your ~/.netrc file:

  1. Log into the Heroku web interface
  2. Navigate to your Account settings page
  3. Scroll down to the API Key section and click the Reveal button
  4. Copy your API key
  5. Open your ~/.netrc file, or create it, with your favourite text editor

  6. Add the following content:

    machine api.heroku.com   login <your-email@address>   password <your-api-key> machine git.heroku.com   login <your-email@address>   password <your-api-key>

    Replace <your-email@address> with the email address registered with Heroku, and <your-api-key> with the API key you copied from Heroku.

This should manually accomplish what heroku login does automatically. However, I don't recommend this. Running heroku login does the same thing more easily and with fewer opportunities to make a mistake.

If you decide to copy ~/.netrc files between machines or accounts you should be aware of two major caveats:

  • This file is used by many other programs; be careful to only copy the configuration stanzas you want.
  • Your API key offers full programmatic access to your account. You should protect it as strongly as you protect your password.

Please be very careful if you intend to log into Heroku using any mechanism other than heroku login.


You can generate a non-expiring OAuth token then pass it to the CLI via an environment variable. This is useful if you need to run Heroku CLI commands indefinitely from a scheduler and you don't want the login to expire. Do it like this (these are not actual Tokens and IDs, BTW):

$ heroku authorizations:create Creating OAuth Authorization... done Client:      <none> ID:          80fad839-876b-4ea0-a41e-6a9a2fb0cf97 Description: Long-lived user authorization Scope:       global Token:       ddf4a0e5-9294-4c5f-8820-b51c52fce4f9 Updated at:  Fri Aug 02 2019 21:26:09 GMT+0100 (British Summer Time) (less than a minute ago)

Get the token (not the ID) from that authorization and pass that it to your CLI:

$ HEROKU_API_KEY='ddf4a0e5-9294-4c5f-8820-b51c52fce4f9' heroku run ls --app my-app Running ls on ⬢ my-app... up, run.2962 (Hobby) <some file names> $

Are Regular VACUUM ANALYZE Still Recommended Under 9.1?

Answer : VACUUM is only needed on updated or deleted rows in non-temporary tables. Obviously you're doing lots of INSERTs but it's not obvious from the description that you're also doing lots of UPDATEs or DELETEs. These operations can be tracked with the pg_stat_all_tables view, specifically the n_tup_upd and n_tup_del columns. Also, even more to the point, there is a n_dead_tup column that tells, per table, how much rows need to be vacuumed. (see Monitoring statistics in the doc for functions and views related to statistics gathering). A possible strategy in your case would be to suppress the scheduled VACUUM, keeping an eye on this view and checking on which tables the n_dead_tup is going up significantly. Then apply the aggressive VACUUM to these tables only. This will be a win if there are large tables whose rows never get deleted nor updated and the aggressive VACUUM is really necessary only on smaller tables. But keep running the ANALYZE for the optimiz

Can Feynman Diagrams Be Used To Represent Any Perturbation Theory?

Answer : Diagram machinery works also for perturbation theory in classical statistical mechanics and classical field theories. Generally, various kinds of diagrams constitute a pictorial way of talking about tensor products and their contractions while hiding the multi-linear algebra from the layman. In the simplest case, vertices (or blobs) represent vectors, matrices, tensors; vertices have ingoing and/or outgoing ports; ingoing ports denote (contravariant) ro indices; outgoing ports denote (covariant) co indices; directed arcs between blobs give a pair of equal indices summed over; different base spaces ⇔ \Leftrightarrow ⇔ different arc types; symmetric tensors ⇔ \Leftrightarrow ⇔ undirected diagrams; no labels are needed for internal lines. In many cases, the directed arcs are decorated (as thin, thick, broken,wavy, curly lines), each decoration indicating the presence of a so-called propagator, a function of its label to use as a weight in the sum, which may beco
