fuzzy translations Sometimes makemessages may think that the string it found for translation is somewhat similar to already existing translation. It will when mark it in the .po file with a special fuzzy comment like this: #: templates/randa/map.html:91 #, fuzzy msgid "Country" msgstr...

Cassandra uses two kinds of keys: the Partition Keys is responsible for data distribution across nodes the Clustering Key is responsible for data sorting within a partition A primary key is a combination of those to types. The vocabulary depends on the combination: simple primary key: only...

Declaring a key The table creation statement should contain a PRIMARY KEY expression. The way you declare it is very important. In a nutshell: PRIMARY KEY(partition key) PRIMARY KEY(partition key, clustering key) Additional parentheses group multiple fields into a composite partition key or de...

The partition key is the minimum specifier needed to perform a query using a where clause. If you declare a composite clustering key, the order matters. Say you have the following primary key: PRIMARY KEY((part_key1, part_key_2), (clust_key_1, clust_key_2, clust_key_3)) Then, the only valid qu...

First you disable your network card's automatic checksumming: sudo ethtool -K eth1 tx off Then send your packet, using a SOCK_RAW socket: #!/usr/bin/env python from socket import socket, AF_PACKET, SOCK_RAW s = socket(AF_PACKET, SOCK_RAW) s.bind(("eth1", 0)) # We're putting toge...

Returns the value of any OS environment variable. MESSAGE OS-GETENV ("OS") VIEW-AS ALERT-BOX. On a Windows machine: MESSAGE OS-GETENV ("SHELL") VIEW-AS ALERT-BOX. Result on a Linux machine with Bash as current shell: ┌────── Message ───────┐ ...

Creates a directory, status is in OS-ERROR OS-CREATE-DIR directory Create a directory called /usr/local/appData OS-CREATE-DIR VALUE("/usr/local/appData").

Returns a list of all drives on a system. MESSAGE OS-DRIVES VIEW-AS ALERT-BOX. Result with four drives, C through F: On Linux the list will simply be empty as there by definitions are no "drives" connected. Listing directories is done in another way (INPUT FROM OS-DIR)

Client metrics cover the traffic between the client and the Varnish cache. sess_conn - Cumulative number of connections. client_req - Cumulative number of client requests. sess_dropped - Dropped connections because of a full queue. Monitor sess_conn and client_req to keep track of traffic vo...

You monitor the cached objects to see how often they expire and if they are "nuked". n_expired - Number of expired objects. n_lru_nuked - Last recently used nuked objects. Number of objects nuked (removed) from the cache because of lack of space. varnishstat -1 | grep "n_expire...

You need to keep track of some threads metrics to watch your Varnish Cache. Is it running out of OS resources or is it functioning well. threads - Number of threads in all pools. threads_created - Number of created threads. threads_failed - Number of times Varnish failed to create a thread. th...

There are a number of metrics describing the communication between Varnish and it's backends. The most important metrics here might be these: backend_busy - Number of http 5xx statuses recieved by a backend. With VCL you can configure Varnish to try another backend if this happens. backend_fail...

TypeScript enables editors to provide contextual documentation: You'll never forget whether String.prototype.slice takes (start, stop) or (start, length) again!

TypeScript allows editors to perform automated refactors which are aware of the rules of the languages. Here, for instance, Visual Studio Code is able to rename references to the inner foo without altering the outer foo. This would be difficult to do with a simple find/replace.
