Chrome Extension Manifest 'Matches'


Answer :

You need to surround the value of the content_scripts field in square brackets:

"content_scripts": [ {   "matches": ["http://*"],   "js": ["scripts.js"] } ]

(see the Chrome Docs for more info)

Incidentally, using http://*/* would be a better match for all urls (see the docs), adding https://*/* if you also need to match those as well.

Edit:

Following your edit, the error you are getting is because of the match pattern being incorrect.


If you want to match every URL, then Google has a special pattern just for this purpose: <all_urls>

Sample usage:

"matches": ["<all_urls>"],

See this page for more info: https://developer.chrome.com/extensions/match_patterns


Any match pattern should be of the following structure [scheme]://[host][path]

  1. scheme is '*' | 'http' | 'https' | 'file' | 'ftp'
  2. host is '' | '.' (any char except '/' and '*')+
  3. path is '/' (any chars)

For matching any HTTP/S and FILE URL use: 

 "matches": [     "*://*/*",     "file://*/*"   ],

Ref: https://developer.chrome.com/apps/match_patterns

By the way, in order to allow access to local files - add the permission:

"permissions": [    "file://*/*" ]

Or approve file access on the extension settings page.

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
