mongoc_uri_t¶
Synopsis¶
typedef struct _mongoc_uri_t mongoc_uri_t;
Description¶
mongoc_uri_t
provides an abstraction on top of the MongoDB connection URI format. It provides standardized parsing as well as convenience methods for extracting useful information such as replica hosts or authorization information.
See Connection String URI Reference on the MongoDB website for more information.
Format¶
mongodb[+srv]:// <1>
[username:password@] <2>
host1 <3>
[:port1] <4>
[,host2[:port2],...[,hostN[:portN]]] <5>
[/[database] <6>
[?options]] <7>
“mongodb” is the specifier of the MongoDB protocol. Use “mongodb+srv” with a single service name in place of “host1” to specify the initial list of servers with an SRV record.
An optional username and password.
The only required part of the uri. This specifies either a hostname, IPv4 address, IPv6 address enclosed in “[” and “]”, or UNIX domain socket.
An optional port number. Defaults to :27017.
Extra optional hosts and ports. You would specify multiple hosts, for example, for connections to replica sets.
The name of the database to authenticate if the connection string includes authentication credentials. If /database is not specified and the connection string includes credentials, defaults to the ‘admin’ database.
Connection specific options.
Note
Option names are case-insensitive. Do not repeat the same option (e.g. “mongodb://localhost/db?opt=value1&OPT=value2”) since this may have unexpected results.
The MongoDB C Driver exposes constants for each supported connection option. These constants make it easier to discover connection options, but their string values can be used as well.
For example, the following calls are equal.
uri = mongoc_uri_new ("mongodb://localhost/?" MONGOC_URI_APPNAME "=applicationName");
uri = mongoc_uri_new ("mongodb://localhost/?appname=applicationName");
uri = mongoc_uri_new ("mongodb://localhost/?appName=applicationName");
Replica Set Example¶
To describe a connection to a replica set named ‘test’ with the following mongod hosts:
db1.example.com
on port27017
db2.example.com
on port2500
You would use a connection string that resembles the following.
mongodb://db1.example.com,db2.example.com:2500/?replicaSet=test
SRV Example¶
If you have configured an SRV record with a name like “_mongodb._tcp.server.example.com” whose records are a list of one or more MongoDB server hostnames, use a connection string like this:
uri = mongoc_uri_new ("mongodb+srv://server.example.com/?replicaSet=rs&appName=applicationName");
The driver prefixes the service name with “_mongodb._tcp.”, then performs a DNS SRV query to resolve the service name to one or more hostnames. If this query succeeds, the driver performs a DNS TXT query on the service name (without the “_mongodb._tcp” prefix) for additional URI options configured as TXT records.
On Unix, the MongoDB C Driver relies on libresolv to look up SRV and TXT records. If libresolv is unavailable, then using a “mongodb+srv” URI will cause an error. If your libresolv lacks res_nsearch
then the driver will fall back to res_search
, which is not thread-safe.
IPv4 and IPv6¶
If connecting to a hostname that has both IPv4 and IPv6 DNS records, the behavior follows RFC-6555. A connection to the IPv6 address is attempted first. If IPv6 fails, then a connection is attempted to the IPv4 address. If the connection attempt to IPv6 does not complete within 250ms, then IPv4 is tried in parallel. Whichever succeeds connection first cancels the other. The successful DNS result is cached for 10 minutes.
As a consequence, attempts to connect to a mongod only listening on IPv4 may be delayed if there are both A (IPv4) and AAAA (IPv6) DNS records associated with the host.
To avoid a delay, configure hostnames to match the MongoDB configuration. That is, only create an A record if the mongod is only listening on IPv4.
Connection Options¶

Key |
Default |
Description |
|---|---|---|---|
MONGOC_URI_RETRYREADS |
retryreads |
true |
If “true” and the server is a MongoDB 3.6+ standalone, replica set, or sharded cluster, the driver safely retries a read that failed due to a network error or replica set failover. |
MONGOC_URI_RETRYWRITES |
retrywrites |
true if driver built w/ TLS |
If “true” and the server is a MongoDB 3.6+ replica set or sharded cluster, the driver safely retries a write that failed due to a network error or replica set failover. Only inserts, updates of single documents, or deletes of single documents are retried. |
MONGOC_URI_APPNAME |
appname |
Empty (no appname) |
The client application name. This value is used by MongoDB when it logs connection information and profile information, such as slow queries. |
MONGOC_URI_TLS |
tls |
Empty (not set, same as false) |
{true|false}, indicating if TLS must be used. (See also mongoc_client_set_ssl_opts() and mongoc_client_pool_set_ssl_opts().) |
MONGOC_URI_COMPRESSORS |
compressors |
Empty (no compressors) |
Comma separated list of compressors, if any, to use to compress the wire protocol messages. Snappy, zlib, and zstd are optional build time dependencies, and enable the “snappy”, “zlib”, and “zstd” values respectively. |
MONGOC_URI_CONNECTTIMEOUTMS |

false |
If true, this indicates the driver is connecting to a MongoDB cluster behind a load balancer. |
MONGOC_URI_SRVMAXHOSTS |
srvmaxhosts |
0 |
If zero, the number of hosts in DNS results is unlimited. If greater than zero, the number of hosts in DNS results is limited to being less than or equal to the given value. |

Server Discovery, Monitoring, and Selection Options¶
Clients in a mongoc_client_pool_t share a topology scanner that runs on a background thread. The thread wakes every heartbeatFrequencyMS
(default 10 seconds) to scan all MongoDB servers in parallel. Whenever an application operation requires a server that is not known–for example, if there is no known primary and your application attempts an insert–the thread rescans all servers every half-second. In this situation the pooled client waits up to serverSelectionTimeoutMS
(default 30 seconds) for the thread to find a server suitable for the operation, then returns an error with domain MONGOC_ERROR_SERVER_SELECTION
.
Technically, the total time an operation may wait while a pooled client scans the topology is controlled both by serverSelectionTimeoutMS
and connectTimeoutMS
. The longest wait occurs if the last scan begins just at the end of the selection timeout, and a slow or down server requires the full connection timeout before the client gives up.
A non-pooled client is single-threaded. Every heartbeatFrequencyMS
, it blocks the next application operation while it does a parallel scan. This scan takes as long as needed to check the slowest server: roughly connectTimeoutMS
. Therefore the default heartbeatFrequencyMS
for single-threaded clients is greater than for pooled clients: 60 seconds.
By default, single-threaded (non-pooled) clients scan only once when an operation requires a server that is not known. If you attempt an insert and there is no known primary, the client checks all servers once trying to find it, then succeeds or returns an error with domain MONGOC_ERROR_SERVER_SELECTION
. But if you set serverSelectionTryOnce
to “false”, the single-threaded client loops, checking all servers every half-second, until serverSelectionTimeoutMS
.
The total time an operation may wait for a single-threaded client to scan the topology is determined by connectTimeoutMS
in the try-once case, or serverSelectionTimeoutMS
and connectTimeoutMS
if serverSelectionTryOnce
is set “false”.
Constant |
Key |
Description |
|---|---|---|
MONGOC_URI_HEARTBEATFREQUENCYMS |
heartbeatfrequencyms |
The interval between server monitoring checks. Defaults to 10,000ms (10 seconds) in pooled (multi-threaded) mode, 60,000ms (60 seconds) in non-pooled mode (single-threaded). |
MONGOC_URI_SERVERSELECTIONTIMEOUTMS |
serverselectiontimeoutms |
A timeout in milliseconds to block for server selection before throwing an exception. The default is 30,0000ms (30 seconds). |
MONGOC_URI_SERVERSELECTIONTRYONCE |
serverselectiontryonce |
If “true”, the driver scans the topology exactly once after server selection fails, then either selects a server or returns an error. If it is false, then the driver repeatedly searches for a suitable server for up to |
MONGOC_URI_SOCKETCHECKINTERVALMS |
socketcheckintervalms |
Only applies to single threaded clients. If a socket has not been used within this time, its connection is checked with a quick “hello” call before it is used again. Defaults to 5,000ms (5 seconds). |
MONGOC_URI_DIRECTCONNECTION |
directconnection |
If “true”, the driver connects to a single server directly and will not monitor additional servers. If “false”, the driver connects based on the presence and value of the |
Setting any of the *TimeoutMS options above to 0
will be interpreted as “use the default value”.
Connection Pool Options¶
These options govern the behavior of a mongoc_client_pool_t. They are ignored by a non-pooled mongoc_client_t.
Constant |
Key |
Description |
|---|---|---|
MONGOC_URI_MAXPOOLSIZE |
maxpoolsize |
The maximum number of clients created by a mongoc_client_pool_t total (both in the pool and checked out). The default value is 100. Once it is reached, mongoc_client_pool_pop() blocks until another thread pushes a client. |
MONGOC_URI_MINPOOLSIZE |
minpoolsize |
Deprecated. This option’s behavior does not match its name, and its actual behavior will likely hurt performance. |
MONGOC_URI_MAXIDLETIMEMS |
maxidletimems |
Not implemented. |
MONGOC_URI_WAITQUEUEMULTIPLE |
waitqueuemultiple |
Not implemented. |
MONGOC_URI_WAITQUEUETIMEOUTMS |
waitqueuetimeoutms |
The maximum time to wait for a client to become available from the pool. |
Write Concern Options¶
Constant |
Key |
Description |
|---|---|---|
MONGOC_URI_W |
w |
Determines the write concern (guarantee). Valid values:
|
MONGOC_URI_WTIMEOUTMS |
wtimeoutms |
The time in milliseconds to wait for replication to succeed, as specified in the w option, before timing out. When wtimeoutMS is 0, write operations will never time out. |
MONGOC_URI_JOURNAL |
journal |
Controls whether write operations will wait until the mongod acknowledges the write operations and commits the data to the on disk journal.
|
Read Concern Options¶
Constant |
Key |
Description |
|---|---|---|
MONGOC_URI_READCONCERNLEVEL |
readconcernlevel |
The level of isolation for read operations. If the level is left unspecified, the server default will be used. See readConcern in the MongoDB Manual for details. |
Read Preference Options¶
When connected to a replica set, the driver chooses which member to query using the read preference:
Choose members whose type matches “readPreference”.
From these, if there are any tags sets configured, choose members matching the first tag set. If there are none, fall back to the next tag set and so on, until some members are chosen or the tag sets are exhausted.
From the chosen servers, distribute queries randomly among the server with the fastest round-trip times. These include the server with the fastest time and any whose round-trip time is no more than “localThresholdMS” slower.
Constant |
Key |
Description |
|---|---|---|
MONGOC_URI_READPREFERENCE |
readpreference |
Specifies the replica set read preference for this connection. This setting overrides any secondaryOk value. The read preference values are the following:
|
MONGOC_URI_READPREFERENCETAGS |
readpreferencetags |
A representation of a tag set. See also Tag Sets. |
MONGOC_URI_LOCALTHRESHOLDMS |
localthresholdms |
How far to distribute queries, beyond the server with the fastest round-trip time. By default, only servers within 15ms of the fastest round-trip time receive queries. |
MONGOC_URI_MAXSTALENESSSECONDS |
maxstalenessseconds |
The maximum replication lag, in wall clock time, that a secondary can suffer and still be eligible. The smallest allowed value for maxStalenessSeconds is 90 seconds. |
Note
When connecting to more than one mongos, libmongoc’s localThresholdMS applies only to the selection of mongos servers. The threshold for selecting among replica set members in shards is controlled by the mongos’s localThreshold command line option.
Legacy Options¶
For historical reasons, the following options are available. They should however not be used.
Constant |
Key |
Description |
|---|---|---|
MONGOC_URI_SAFE |
safe |
{true|false} Same as w={1|0} |

FOI release
Entitlements to free school meals after the working tax credit changes in April 2012.
On 6 April 2012 working tax credit changed. This meant couples with children had to work 24 hours a week rather than 16 to qualify for working tax credit. Can you please tell me how many children in the country have lost entitlement to free school meals because of this change?
And how many couples with children in the country have been affected by this change? I would also appreciate a breakdown by region if possible.
Q1. No children lost entitlement to a free school meal because of the change to working tax credit. Families would be more likely to be entitled under the change. In England, children are eligible to receive free school meals ( FSM ) if their parents are in receipt of any of the following benefits:
The free school meal eligibility criteria can be found on our website.
Q2. You have asked how many couples with children have been effected by this change. We do not hold this information. You may wish to contact HMRC with a request for information .

At Cab Calloway School of the Arts Middle School, Business Professionals of America (BPA), is a club that many students join and enjoy. It is a Career and Technical Student Organization that allows students to further their pursuance in careers dealing with management, administration, information technology, and many other career fields that are related. Unfortunately, because there was not a computer class at Cab Calloway High School, members entering the High School during the 2010/2011 school year, wouldn't have a BPA club to join.
Because of a large interest in technology, the High School Communication Arts teacher Mrs. Fanny worked hard to meet the interests of students and in 2010, the Cab Calloway TSA Chapter was founded. In 2011, our Chapter made it all the way to Nationals. Unfortunately we didn't place in anything but members enjoyed the experience and the opportunity. TSA allowed them to create strong bonds with other peers that they would have never imagined and to meet and make new friends at Nationals in Dallas, Texas.
Members came back the next school year excited and ready to start having lunch meetings, creating groups, and working together. In the midst of the hard work, a quarter through the year, our teacher Mrs. Fanny announced that she was going to retire at the end of the semester. The Communication Arts Department received a new teacher, Mr. Greider, halfway through the school year. Starting as a teacher in the middle of the school year was indeed very stressful and hectic for him. Trying to handle so many different tasks while also trying to manage a club was very new to him. However all of the members pulled through to not only help him but each other.
In 2012, the Chapter went to Nationals in Nashville, Tennessee, for the second year in a row. We placed 1st place nationally in System Control Technology, Webmaster, Promotional Graphics, and 2nd place in Promotional Graphics.
Since then there has been a boost of interest in the club and we have experienced an increase in membership. All of the members are very devoted and work hard and together effectively to get the job done. Although we do work hard and are always focused on our task, there is always room for a little fun. Our Chapter promotes and friendly environment where students can socialize with other students that have the same interests as them. It allows them to make friends and many lasting memories that they will have to remember and cherish on.
Though we are a young club, our achievements and chapter as a group have continuously increased. We've accomplished going to nationals twice, two consecutive years, and as we continue on our third year we hope to do the same. We hope that we will continue to receive accolades in the TSA student organization in all the years to come!

It was an amazing experience making a website today. If you love STEM, this would be an amazing experience to have. You can do this at home. Anywhere that has a computer or laptop. This website is the very first website I have ever made. I had so much fun creating this.
At first, I didn't know what STEM was, but now I do. I'd like to thank my teacher, Ms. Wilson, for helping me out. I want to be a Chemical Engineer as an adult. I am a very hands-on learner. I am in the 7th grade.
Hey. My name is Camay!!


Interface ExtendedServer
-
public interface ExtendedServer
The extended API for Database.This provides the finder methods that take an explicit transaction rather than obtaining the transaction from the usual mechanism (which is ThreadLocal based).
In general we only want to use this ExtendedServer API when we want to avoid / bypass the use of the mechanism to get the current transaction and instead explicitly supply the transaction to use.
Note that in all cases the transaction supplied can be null and in this case the Database will use the normal mechanism to obtain the transaction to use.

Method Detail
-
clockNow
long clockNow()
Return the NOW time from the Clock.
-
setClock
void setClock(Clock clock)
Set the Clock to use for@WhenCreated
and@WhenModified
.Note that we only expect to change the Clock for testing purposes.
-
exists
<T> boolean exists(Query<?> ormQuery, Transaction transaction)
Execute the query returning true if a row is found.The query is executed using max rows of 1 and will only select the id property. This method is really just a convenient way to optimise a query to perform a 'does a row exist in the db' check.
Example:
boolean userExists = query().where().eq("email", "rob@foo.com").exists();
Example using a query bean:
boolean userExists = new QContact().email.equalTo("rob@foo.com").exists();
- Returns:
- True if the query finds a matching row in the database
-
findCount
<T> int findCount(Query<T> query, Transaction transaction)
Return the number of 'top level' or 'root' entities this query should return.- See Also:
Query.findCount()
,Query.findFutureCount()
-
findIds
@Nonnull  List findIds(Query<T> query, Transaction transaction)
Return the Id values of the query as a List.- See Also:
Query.findIds()
-
findIterate
@Nonnull <T> QueryIterator<T> findIterate(Query<T> query, Transaction transaction)
Return a QueryIterator for the query.Generally using
findEach(Query, Consumer, Transaction)
orfindEachWhile(Query, Predicate, Transaction)
is preferred to findIterate(). The reason is that those methods automatically take care of closing the queryIterator (and the underlying jdbc statement and resultSet).This is similar to findEach in that not all the result beans need to be held in memory at the same time and as such is good for processing large queries.
-
findStream
@Nonnull <T> Stream<T> findStream(Query<T> query, Transaction transaction)
Execute the query returning the result as a Stream.Note that this can support very large queries iterating any number of results. To do so internally it can use multiple persistence contexts.
Note that the stream needs to be closed so use with try with resources.
-
findLargeStream
@Nonnull @Deprecated <T> Stream<T> findLargeStream(Query<T> query, Transaction transaction)
Deprecated.Deprecated - migrate to findStream().Execute the query returning the result as a Stream.
Note that this can support very large queries iterating any number of results. To do so internally it can use multiple persistence contexts.
Note that the stream needs to be closed so use with try with resources.
-
findEach
<T> void findEach(Query<T> query, Consumer<T> consumer, Transaction transaction)
Execute the query visiting the each bean one at a time.Unlike findList() this is suitable for processing a query that will return a very large resultSet. The reason is that not all the result beans need to be held in memory at the same time and instead processed one at a time.
Internally this query using a PersistenceContext scoped to each bean (and the beans associated object graph).
DB.find(Order.class) .where().eq("status", Order.Status.NEW) .order().asc("id") .findEach((Order order) -> { // do something with the order bean System.out.println(" -- processing order ... " + order); });
-
findEach
<T> void findEach(Query<T> query, int batch, Consumer<List<T>> consumer, Transaction t)
Execute findEach with batch consumer.- See Also:
Query.findEach(int, Consumer)
-
findEachWhile
<T> void findEachWhile(Query<T> query, Predicate<T> consumer, Transaction transaction)
Execute the query visiting the each bean one at a time.Compared to findEach() this provides the ability to stop processing the query results early by returning false for the Predicate.
Unlike findList() this is suitable for processing a query that will return a very large resultSet. The reason is that not all the result beans need to be held in memory at the same time and instead processed one at a time.
Internally this query using a PersistenceContext scoped to each bean (and the beans associated object graph).
DB.find(Order.class) .where().eq("status", Order.Status.NEW) .order().asc("id") .findEachWhile((Order order) -> { // do something with the order bean System.out.println(" -- processing order ... " + order); boolean carryOnProcessing = ... return carryOnProcessing; });
-
findVersions
@Nonnull <T> List<Version<T>> findVersions(Query<T> query, Transaction transaction)
Return versions of a @History entity bean.Generally this query is expected to be a find by id or unique predicates query. It will execute the query against the history returning the versions of the bean.
-
findList
@Nonnull <T> List<T> findList(Query<T> query, Transaction transaction)
Execute a query returning a list of beans.Generally you are able to use
Query.findList()
rather than explicitly calling this method. You could use this method if you wish to explicitly control the transaction used for the query.List<Customer> customers = DB.find(Customer.class) .where().ilike("name", "rob%") .findList();
- Type Parameters:
T
- the type of entity bean to fetch.- Parameters:
query
- the query to execute.transaction

- See Also:
Query.findList()
-
findFutureCount
@Nonnull <T> FutureRowCount<T> findFutureCount(Query<T> query, Transaction transaction)

query
- the query to execute the row count ontransaction
- the transaction (can be null).- Returns:
- a Future object for the row count query
- See Also:
Query.findFutureCount()
-
findFutureIds
@Nonnull <T> FutureIds<T> findFutureIds(Query<T> query, Transaction transaction)
Execute find Id's query in a background thread.This returns a Future object which can be used to cancel, check the execution status (isDone etc) and get the value (with or without a timeout).

This query will execute in it's own PersistenceContext and using its own transaction. What that means is that it will not share any bean instances with other queries.
- Parameters:
query
- the query to execute in the backgroundtransaction
- the transaction (can be null).- Returns:
- a Future object for the list result of the query
- See Also:
Query.findFutureList()
-
findPagedList
@Nonnull <T> PagedList<T> findPagedList(Query<T> query, Transaction transaction)
Return a PagedList for this query using firstRow and maxRows.The benefit of using this over findList() is that it provides functionality to get the total row count etc.
If maxRows is not set on the query prior to calling findPagedList() then a PersistenceException is thrown.
PagedList<Order> pagedList = DB.find(Order.class) .setFirstRow(50) .setMaxRows(20) .findPagedList(); // fetch the total row count in the background pagedList.loadRowCount(); List<Order> orders = pagedList.getList(); int totalRowCount = pagedList.getTotalRowCount();

List<String> names = DB.find(Customer.class) .select("name") .order().asc("name") .findSingleAttributeList();
Example 2:
List<String> names = DB.find(Customer.class) .setDistinct(true) .select("name") .where().eq("status", Customer.Status.NEW) .order().asc("name") .setMaxRows(100) .findSingleAttributeList();

Big Bang's Taeyang and Daesung discharged from the military
by olmalOn the morning of November 10 KST, Big Bang's Taeyang and Daesung were discharged from the army. With their discharge today, now all of Big Bang's current members have finished their mandatory military service.
Taeyang and Daesung were discharged from Gyeonggi-do Yongin's Ground Operation Headquarters. Their service bases were one of the locations being cared for the ASF virus, and because fans and media are expected to come to their discharge, the Ministry of Defense had decided to change where they will be discharged.
Are you excited about their return to society?


Prodyogiki Sangam, better known as ProSang, is the annual Techfest of Robotics and Aeroclub of MNNIT. It is an initiative to fulfill the basic need to help students score the gap between industrial skill set requirements and academics, hence motivating them to model solutions to real-world problems.
Many talks to gain insights from Industry experts and get a chance to network and meet top heads in various fields, thus helping students from diverse background understand the current trends and needs.
Cut-throat competition in challenging events thrills the students and encourages them to make products to solve challenging problems put to them in the form of problem statements.
Several workshops are organized on IoT, drone automation, etc., giving students hands-on experience and honing their skill set. They also experience the atmosphere of a National Institute of Technology, see technical workshops, visit labs, and much more.
Students of our clubs and outside display projects built throughout the year to professors from all college departments and benefit from their valuable insights in the project exhibition. Further, interaction of junior with their senior colleagues help them to identify their area of interest and future work.
Every year ProSang witnesses adrenaline packed events like Airshows, and out of the box event's like star gazing and Astronomy workshops, conducted by professionals, who are experts in their respective fields

OpenRouteService.org as offers Routing services by using user-generated, collaboratively collected free geographic data from OpenStreetMap.org - Please donate your geographic data to openstreetmap.org!
The service is based on open standards by the Open Geospatial Consortium (OGC). Currently the following services have been implemented within the frame of OpenRouteService.org, which allow you to include maps, geocoding, directories and other content in your web pages or applications. By accessing, requesting and using OpenRouteService (ORS) and the provided API, you are agreeing to our terms of use.
If you intend to use OpenRouteService in your own applications please contact us. We are interested in spreading the usage of OpenRouteService in academic and non-profit projects.
In case you have any further questions, concerns or feedback about this service agreement, please contact us via Email:

Routing services are probably the most important application for street data - apart from visualizing them on a map. While there are a range of desktop (or even mobile) applications that can provide such functionalities also in combination with OSM data, we focus here on an approach based on the concept of interoperable Service Oriented Architectures (SOA). These are regarded as an important concept for forthcoming software architectures in general, and more and more being applied also in the GI (geographic information) sector. While SOA offer many benefits they are not the solution to all problems.
A remaining issue is the question of interoperability between different web services from different vendors offering the same or similar services but with different technical programming interfaces. This is the reason why standards are becoming more and more important for a range of applications - in particular in the institutional and governmental sector, but also beyond. Within the geographical information community here the Open Geospatial Consortium (OGC) has developed a range of standards for different GI related functionalities. This is why we choose to develop and set up a routing service that uses OSM data and provides those through the standardized interface specified by the OGC within the Open Location Services initiative (OpenLS or OLS) as one of 5 services:
The Route Service offers a broad range of possibilities, among them several parameters that determine the result, e.g.:
Currently openrouteservice.org offers a end-user oriented website with an interactive map , but soon we will also make the route service available as OGC-web service, that can be used through http-based xml-requestes as specified in the OGC OpenLS Route Service specification. This will allow developers to use this servide in an open and interoperable way easily within their own applications.
OpenRouteService APIs and services are currently available worldwide, except for North- and South America (see Figure of current coverage), due to our limited server capacities. We are planning on providing ORS also worldwide in the future but cannot provide any timeline at the moment.
OpenLS Services
(Status 01.09.2015)
Description: Through the OpenLS interface requests can be generated to the appropriate services without further query limitations. The offered API's are valid for one year.
In case you plan a long-term use of the interfaces within your projects , please contact us via Email

Hands-On Data Structures and Algorithms with Kotlin by Chandra Sekhar Nayak, Rivu Chakraborty, starts with the basics of algorithms and data structures, helping you get to grips with the fundamentals and measure complexity. You'll then move on to exploring the basics of functional programming while getting used to thinking recursively. Packed with plenty of examples along the way, this book will help you grasp each concept easily. In addition to this, you'll get a clear understanding of how the data structures in Kotlin's collection framework work internally. By the end of this book, you will be able to apply the theory of data structures and algorithms to work out real-world problems.

Changes in marijuana laws have not been found to have a significant impact on rates of adult use.
"There is little evidence that decriminalization of marijuana use necessarily leads to a substantial increase in marijuana use." - The National Academy of Sciences
In short: legal access ≠ increased use.
When it comes to use by young people, several recent reports have found that in the majority of states that have approved medical marijuana, use among teenagers has actually decreased.
Experts say this is due to a diminished “forbidden fruit” effect and decreased access to marijuana as it moves from the unregulated streets – where there are no age requirements – to inside licensed dispensaries, where you need to be 21 to purchase marijuana.

--- layout: post title: Mid-run Ditch-water Shower date: 2012-12-24 14:07:17.000000000 +00:00 tags: - Christmas - grumble - traffic type: post published: true ---
A very merry f***ing Christmas goes out to the white van driver who thought I needed a ditch-water shower right in the middle of my run along the A4 outside Twyford today.
You made absolutely no attempt to slow down or avoid the huge puddle. Instead you created an arching splash of about 10 feet in height that I couldn't avoid. There is a law against this in this country, but I guess as a stereo-typical white van driver you must think this only applies to other people.
I know this was probably very funny to you and I certainly laughed in disbelief (after I'd finished effing and jeffing and gesticulating at you) at just how inconsiderate you were. I also had a chortle to myself when I got back when changing and discovered my jocks were soaking too, but that's not the point.
Anyway, as you're lucky enough to have disappeared before I could get your registration number and as it's Christmas I'll let you off.  I hope they wake you up nice and early tomorrow morning and then fall into a right grumpy mood and really get up your nose because Santa didn't bring them anything they wanted - they're on the bad list now after all 😉 .
Merry Christmas inconsiderate stereo-typical white van man.
