extensible storage engine ( ese ) , also known as jet blue , is an isam ( indexed sequential access method ) data storage technology from microsoft .

ese is the core of microsoft exchange server , active directory , branch cache , and windows search .

it 's also used by a number of windows components including windows update client and help and support center .

its purpose is to allow applications to store and retrieve data via indexed and sequential access .

ese provides transacted data update and retrieval .

a crash recovery mechanism is provided so that data consistency is maintained even in the event of a system crash .

transactions in ese are highly concurrent making ese suitable for server applications .

ese caches data intelligently to ensure high performance access to data .

in addition , ese is lightweight making it suitable for auxiliary applications .

the ese runtime ( esent.dll ) has shipped in every windows release since windows 2000 , with native x64 version of the ese runtime shipping with x64 versions of windows xp and windows server 2003 .

microsoft exchange , up to exchange 2003 shipped with only the 32-bit edition , as it was the only supported platform .

with exchange 2007 , it ships with the 64-bit edition .

the extensible storage engine is an advanced and sequential method to use the stored and retrieved data from tables . it supports few schemas that includes wide tables with many sparse and multi - valued columns , as well as sparse and rich indexes . while accessing the data , it enables to store the data for maximize the performance . the edb server allows to access the data from ese ( extensible storage engine ) and to store the database in hierarchical storage format that includes messages , folders and attachments , etc . these files stores the rich data ( smtp , mapi and https messages ) in each table and its properties varies . in addition , . edb file extension is accessed directly by ese .
these files belong together and create a so - called “storage group” . during the installation of exchange server one database is created in a storage group . in exchange 2007 the public folder database is created in a second storage group . when replication technology ( like lcr , ccr or scr ) in exchange 2007 is used than only one database per storage group can exist . if no replication technology is used , up to five databases can be created in each storage group .
cql2 was easy to implement since it maps so straightforwardly to what the storage engine has been doing all along . but it turns out there are several major problems with this approach :
extensible storage engine ( esent ) , also known as jet api , is an indexed sequential access method ( isam ) data storage technology from microsoft . the esent runtime has been a part of windows since windows 2000 and has been used in products like microsoft exchange , active directory , windows update , and desktop search . this application stores and retrieves data from tables using indexed or sequential cursor navigation .
alternate storage is completely transparent at the imap / pop level . users accessing mail through imap or pop cannot normally tell if any given message is stored in primary storage or alternate storage . conceivably users might be able to measure a performance difference ; the point is that there is no imap / pop command which could be used to expose this information . it is entirely possible to have a mail folder which contains a mix of messages stored in primary storage and alternate storage .
the main functions of the base engine application programming interface ( api ) are : initialization and global definitions , image analysis functions , similarity comparison functions , scoring functions , and weights management . in addition to the functionality of the base engine , the extensible engine api also has primitive registration and schema management . the entry points for these functions are defined in regular

the vir system technology is built around a core module called the vir engine and operates at the image object level of the vimsys model . there are three main functional parts of the engine : image analysis , image comparison , and management . these are invoked by an application developer . typically , an application developer accesses them during image insertion , image query , and image requery ( a query with the same image but with a different set of weighting factors ) . the function of each unit , and how the application developer uses the vir application programming interface ( api ) to exchange information with the vir engine is described below . the full capabilities of the engine are decomposed into two api sets : a base vir engine , and an extensible vir engine . the base engine provides a fixed set of primitives ( color , texture , structure , etc . ) while the extensible engine provides a set of mechanisms for defining and installing new primitives ( discussed in detail later ) .

it is recommended that you back up your self - hosted engine environment regularly . the supported backup method uses the engine - backup tool and can be performed without interrupting the ovirt - engine service . the engine - backup tool only allows you to back up the red hat enterprise virtualization manager virtual machine , but not the host that contains the manager virtual machine .
this procedure provides an example of the workflow for backing up a self - hosted engine using a failover host . this host can then be used later to deploy the restored self - hosted engine environment . for more information on backing up the self - hosted engine , see section 3 . 10 . 1 , “backing up the self - hosted engine manager virtual machine” .

the nature of the self - hosted engine , and the relationship between the hosts and the hosted - engine virtual machine , means that backing up and restoring a self - hosted engine environment requires additional considerations to that of a standard red hat enterprise virtualization environment . in particular , the hosted - engine hosts remain in the environment at the time of backup , which can result in a failure to synchronize the new host and hosted - engine virtual machine after the environment has been restored .
although the extensible storage engine ( ese ) is a generic database engine , forensic analysis of ese databases seem to be centered around exchange . little information about forensic investigation of ese databases in general , seem to have been published in the public domain . as far as i can tell , mark woan author of esedbviewer , was one of the first who published information about forensic analysis of ese databases in general . this was in 2008 .
microsoft exchange server database uses extensible storage engine ( ese ) which is designed for single client - server architecture . the exchange server directly accesses the data from ese and the database here is stored in hierarchical storage format which includes the messages , folders , attachments , message properties etc . the data stored in each table may have varying property . the information store and ese collaboratively makes up client - server based messaging service for small and large enterprises .

drill uses various database optimizations such as rule based / cost based , as well as data locality and other optimization rules exposed by the storage engine to re - write and split the query . the output of the optimizer is a distributed physical query plan that represents the most efficient and fastest way to execute the query across the different nodes in the cluster . optimization in drill is pluggable , and you can provide rules for optimization at various parts of the query execution . storage plugins can expose optimization rules to drill , leveraging underlying storage engine features to achieve efficient execution .
has been used to deploy a new self - hosted engine and has restored the backup taken in the previous example procedure . deploying the restored environment involves additional steps to that of a regular self - hosted engine deployment :
the script creates the virtual machine to be configured as the manager virtual machine and provides connection details . you must install an operating system on it before the hosted - engine deployment script can proceed on hosted engine configuration .
after host 1 and the engine virtual machine have synchronized and the deployment has been finalized , the environment can be considered operational on a basic level . with only one hosted - engine host , the engine virtual machine is not highly available . however , if necessary , high - priority virtual machines can be started on host 1 .
the extensible storage engine ( ese ) is a database engine that stores information in a logical sequence . information can be retrieved either sequentially or by accessing defined indices . updates to the database are implemented with a transaction in order to ensure secure operations . ese enables simultaneous access to multiple databases , including transaction - log file databases that can be used for system recovery . ese is scalable to large or small applications . the following features are available with the ese application programming interface ( api ) :

at facebook we use mysql to manage many petabytes of data , along with the innodb storage engine that serves social activities such as likes , comments , and shares . while innodb provides great performance and reliability for a variety of workloads , it has inefficiencies on space and write amplification when used with flash storage . a few years ago , we built rocksdb , an embeddable , persistent key - value store for fast storage that has several advantages compared with innodb for space efficiency .
to support this , cassandra ' s storage engine provides wide , sparse rows . these rows can correspond 1 : 1 with business objects , but more often they encode data in the cell name as well as the value - - thus a
row
becomes more of an ( ordered ) map , than a relational row . this is the kind of model we had in mind when we improved the storage engine to allow up to two billion columns per row .
exchange mailbox databases and the queue on hub transport servers and edge transport servers utilize the extensible storage engine ( ese ) database . ese is a multi - user , indexed sequential access method ( isam ) table manager with full data manipulation language ( dml ) and data definition language ( ddl ) capability . ese allows applications to store records and create indexes to access those records in different ways .

despite its advantages , rocksdb does not support replication or an sql layer , and we wanted to continue using those features from mysql . this led us to build myrocks , a new open source project that integrates rocksdb as a new mysql storage engine . with myrocks , we can use rocksdb as backend storage and still benefit from all the features in mysql .
so , a storage group is a set of one or more database files that share a common set of log files .
several important operations occur at the start of exchange storage group backup process . here is the overview of the backup process :
image and video data are much more voluminous than text , and need supporting technology for rapid and efficient storage and retrieval .
if a hosted - engine host is carrying a virtual load at the time of backup , then a host with any of the matching identifiers - ip address , fqdn , or name - cannot be used to deploy a restored self - hosted engine . conflicts in the database will prevent the host from synchronizing with the restored hosted - engine virtual machine . the failover host , however , can be removed from the restored hosted - engine virtual machine prior to synchronization .
a unique name must be provided for the name of the host , to ensure that it does not conflict with other resources that will be present when the engine has been restored from the backup . the name hosted _ engine _ 1 can be used in this procedure because this host was placed into maintenance mode before the environment was backed up , enabling removal of this host between the restoring of the engine and the final synchronization of the host and the engine .
@ ejp but in practice it ' s true , on average , that there is wasted space , even for extensible hashing algorithms . a python dict consumes 50 % more buckets than required ( load factor of 75 % ) . and can you imagine the disk writes required to implement the ' extensible ' part of extensible hash tables ? all of a sudden you hit the limit and your db has to copy and rehash the entire table . and any tables to point to pks in that table , etc . so a single insert might ( unexpectedly ) put your db offline for a painful amount of time . that makes the ' extensible ' part impractical .
we always apply a reasonableness test . depending on what we know about the data , we’ll estimate storage requirement of roughly four times the storage reported in vsphere . in this case that 10tb . for this example , we’d recommend a repository with 8 to 10 tb of storage . this would allow for room to grow and would accommodate any unexpected data growth or high change rates .
after the packages have completed installation , you will be able to continue with restoring the self - hosted engine manager .
in many of its technologies like access or foxpro , microsoft uses the joint engine technology ( jet ) . there are two variants of jet engine : jet red and jet blue . microsoft office applications like access uses jet red that provides a standalone single user database . since it was not developed for a multi - user access and thus considering this limitation , the jet blue was developed that suited the multi - user requirement like exchange server . from the time this technology is used in exchange server , it has evolved to large extent and is incomparable to its original form . microsoft renamed this jet technology as extensible storage engine ( ese ) .

if the deployment of the restored self - hosted engine is on new hardware that has a unique name not present in the backed - up engine , skip this step . this step is only applicable to deployments occurring on the failover host , hosted _ engine _ 1 . because this host was present in the environment at time the backup was created , it maintains a presence in the restored engine and must first be removed from the environment before final synchronization can take place .

in another aspect of the invention , there is a method of extending a search engine for searching a database of visual objects , the method comprising the steps of providing a search engine primitive to extract an attribute from a visual object , and adding a new primitive to the search engine , wherein the new primitive comprises a comparison function for a selected attribute .
the extensible storage engine ( ese ) database format is mainly known for its use in the microsoft exchange , i . e . for the priv1 . edb file . what is less widely known that a lot of microsoft products use this file format , some of which are active directory ( ntds . dit ) , windows ( desktop ) search ( windows . edb ) and windows mail ( windowsmail . msmessagestore ) .
the base vir engine 120 has a fixed or default set of primitives . primitives and their weights are identified and indicated using a tagging mechanism to identify them in the api calls . the default primitives of the presently preferred base engine are :
a failover host , one of the hosted - engine hosts in the environment , must be placed into maintenance mode so that it has no virtual load at the time of the backup . this host can then later be used to deploy the restored self - hosted engine environment . any of the hosted - engine hosts can be used as the failover host for this backup scenario , however the restore process is more straightforward if host 1 is used . the default name for the host 1 host is hosted _ engine _ 1 ; this was set when the hosted - engine deployment script was initially run .
the hosted - engine script detects that the shared storage is being used and asks if this is an additional host setup . you are then prompted for the host id , which must be an integer not already assigned to a host in the environment .
impala does not currently support an extensible serialization - deserialization framework ( serdes ) , and so adding extra functionality to impala is not as straightforward as for hive or pig .
update your dns so that the fully qualified domain name of the red hat enterprise virtualization environment correlates to the ip address of the new manager . in this procedure , fully qualified domain name was set as urltoken . the fully qualified domain name provided for the engine must be identical to that given in the engine setup of the original engine that was backed up .
active directory is implemented on top of an indexed sequential access method ( isam ) table manager , historically called
jet .
this same table manager is used by exchange , file replication service ( frs ) the security configuration editor , certificate services , windows internet name service ( wins ) , and various other windows components . in windowsâ 2000 , this table manager is referred to as the extensible storage engine ( ese ) .
2 . the engine defined in claim 1 , wherein the primitive functions further comprise a comparison function to compare visual objects .
4 . the engine defined in claim 3 , further comprising an analysis function capable of deriving feature data from the object .
the vir engine is intended as an infrastructure around which applications may be developed . image management , thumbnails , database interfaces , and user interfaces are the responsibility of the application developer . in particular , persistent storage of feature vectors is up to the application .
ese is an advanced indexed and sequential access method ( isam ) storage technology for databases of allmost any size from kb to tb .
- backing the storage group up using either of the aforementioned methods will remove the unneeded log files providing you with extra disk space .
with salt , you’ve got a powerful python - based open source management and remote execution application . modular and easily extensible , salt maintains many module types to handle different actions .
cql3 makes one very important changes to how it presents cassandra data : wide rows are
transposed
and unpacked into named columns . from a relational standpoint , you can think of storage engine rows as partitions , within which ( object ) rows are clustered .
secure copy the backup files to the new manager virtual machine . this example copies the files from a network storage server to which the files were copied in section 3 . 10 . 1 , “backing up the self - hosted engine manager virtual machine” . in this example , urltoken is the fully qualified domain name of the storage server , / backup / enginebackupfiles is the designated file path for the backup files on the storage server , and / backup / is the path to which the files will be copied on the new manager .
modern versions of the edge browser no longer stores favorites as files / folders the way you may be accustomed to , and instead uses an internal extensible storage engine ( ese ) database to store favorites . this database is not designed to be
human readable
, so it takes specialized software to be able to do anything meaningful with it . so , this means that you can no longer use the file explorer to manage your favorites .
this procedure provides an example of the workflow for restoring the self - hosted engine environment from a backup . the failover host deploys the new engine virtual machine , which then restores the backup . directly after the backup has been restored , the failover host is still present in the red hat enterprise virtualization manager because it was in the environment when the backup was created . removing the old failover host from the manager enables the new host to synchronize with the engine virtual machine and finalize deployment . for more information on restoring the self - hosted engine , see section 3 . 10 . 2 , “restoring the self - hosted engine environment” .
the reserved transaction log files are created when the engine starts to allow important operations to be logged to get a clean shutdown .
connect to any of the hosted - engine hosts and turn off global maintenance mode . this enables the high - availability agents .
10 . the non - transitory computer - readable storage medium of claim 1 , wherein the embedded accumulator instructions are instructions for modular exponentiation .
the vir engine has a
stateless
architecture in which all of the data about images is managed and stored by the application . applications are responsible for passing
raw
image data ( e . g . , red , green , blue ( rgb ) format buffers ) into the engine , and then handling the feature data and scoring information that is returned to the application by the engine . when a comparison is desired , the application passes the feature data for a pair of images back to the engine to obtain a final score . thus , all persistent data management , query set management , and similar activities , are the responsibility of the application developer . the engine makes no assumptions about storage methodologies , formats , list management , or any information structures that require state information .
the names of the log files are dependent on a three - letter base name , which can be set with jet _ parambasename . the examples below use a base name of
edb
, because that is the default base name . the extension for the transaction log files will be either . log or . jtx depending upon whether the jet _ bitese98filenames is set in the jet _ paramlegacyfilenames parameter . for more information , see extensible storage engine system parameters .
the database engine attempted to replay a create database operation from the transaction log but failed due to an incompatible version of that operation .
microsoft access uses the jet (
joint engine technology
) database technology . in particular it uses the
jet red
database engine , which is a ( basically ) microsoft access specific fork of what was previously a microsoft windows
embedded database
library .
the engine virtual machine is running on host 2 and the six regular virtual machines in the environment are balanced across the three hosts .
to restore a self - hosted engine environment , you must prepare a newly installed red hat enterprise linux system on a physical host .
[ info ] engine replied : db up ! welcome to health status ! [ info ] waiting for the host to become operational in the engine . this may take several minutes . . . [ info ] still waiting for vdsm host to become operational . . .
the host is now able to host the manager virtual machine , and other virtual machines running in the self - hosted engine environment .
cassandra ' s distributed nature also influences the storage engine design . in particular , cassandra recognizes that distributed joins are performance killers : not only do they require lots of expensive random reads , but these reads have to be merged across the network , dramatically increasing the overhead involved .
i find exchange server to be a very complicated system and as in most complicated systems the most
trivial things
may bring it to its knees . one of these
trivial things
is lack of disk space on the disk that holds the log files for a specific storage group . when the information store identifies lack of disk space for a storage group ' s logs it will dismount the stores inside the respective storage group .
vanilladb is a collection of simple - to - read , fast , and extensible database system components aiming to lower the barrier of new - system prototyping and / or learning the database internals .
as a last step , use your favourite ide ( i use vim ) to replace “example” with “upscaledb” and “example” with “upscaledb” . don’t forget to change the cmakelists . txt file as well . then go to the root directory of mysql - server and once more run “cmake” and “make” . the new upscaledb storage engine is now built , the file name is mysql - server / storage / upscaledb / ha _ upscaledb . so .
the purpose of the extensible engine is to provide to the application developer the flexibility of creating and adding custom - made primitives to the system . for example , a face - matching system might construct primitives called
lefteye
and
righteye
, and provide an interface that compares faces based on the similarity of their eyes .
a first embodiment of the invention provides a
base vir engine api
which has a fixed set of visual primitives , and the necessary calls for analyzing and comparing images . a second embodiment of the invention provides an
extensible vir engine api
which allows application developers the ability to create new visual primitives for specialized , vertical applications . this enables application developers to capture higher level semantic information about the images being analyzed , and create intelligent applications in specific domains .

mumsnet co - founder justine roberts told the mail :
of course people can be critical , but for every opinion there is usually a counter one .
easy to dip in and out of ( wish i had had it when i was pregnant ) and done with mumsnet ' s useful humour and easy going attitude .
a conversation then ensued on mumsnet about fathers 4 justice and their tactics , which some members of fathers 4 justice joined . some mumsnetters said some pretty harsh things .
the suggestion that mumsnet encourages gender hatred would be funny if it were not so offensive - and plain silly . the central aim of mumsnet is to make parents ' ( mothers ' and fathers ' ) lives easier . there are many and varied opinions on the site and no one mumsnet party line prevails , save for the view that we respect diverse opinion . we do not pre - moderate or vet comments made to our discussion boards , of which there are around 30 000 every day .
riven vincent , it transpired , had met the prime minister before the election . he had made a private visit to meet her - after an exchange on mumsnet .

when mumsnet tackles issues outside parenting , such as the economy or nuclear power , roberts says , the tweets grow ever more offensive – for example :
britain is going to the dogs . those being the ones in charge of mumsnet .
roberts has been described as having
a haggard face with dried - up ovaries
.
under the high court order , mumsnet must reveal the users real identities and supply copies of all messages posted by skohl and blackfairy7 relating to sorensen or his surgery . sorensen has offered to pay any costs incurred by mumsnet in revealing their members true identities and “not to use the information disclosed save for the purposes of pursuing legal remedies” .
both mr brown and mr cameron did
live chat
sessions with mumsnet , whose members exhibit a marvellous tendency to
ski off - piste
with their interrogations .
mumsnet users sometimes have a vexed relationship with the media , and in recent weeks the site took the producers of eastenders to task over a plotline involving a child abduction .
some of the most venomous mumsnet postings were made three years ago when a debate over the merits of child - care guru gina ford almost caused the site to close .
some of the more fundamentalist fans don ' t like the fact that mumsnet has developed ties with google . roberts doesn ' t see a problem – and i doubt that it will be her last flirtation with the masters of the internet universe . she ' s just signed a deal with vodafone to develop a mumsnet app for the iphone .
the ukip leader replied :
yes , i am embarrassed by it . if they weren ' t members of mumsnet before , they should have left well alone .
this is definitely the last time i do mumsnet ( unless they get jaffa cakes ) .
* yes we know they ' re not a biscuit . . .
on 11 march , fathers 4 justice posted another attack ad this time accusing m & s of
sponsoring hateful , bigoted and prejudiced comments about men and boys on mumsnet
and demanding that m & s withdraw all advertising on mumsnet or face a boycott . it accused the company of
serving up gender hatred for mother ' s day
.
mumsnet was launched in 2000 by carrie longton , a tv producer , and justine roberts , a sports journalist and wife of the guardian ' s deputy editor , ian katz .
our survey of over 1000 mumsnet users showed that the treatment and support women receive following a miscarriage fails to meet official guidelines . here are seven of the most startling shortfalls .
dadsecurity ' s tweets are now offline , but the bbc can confirm it repeatedly posted
rip mumsnet
and claimed to have stolen data from the site before being blocked .
powerful enough to influence westminster . useful enough to pull in more than four million users . yet spiteful enough to attract defamation cases . what ' s the deal with mumsnet ?
according to the newspaper , one mumsnet user had written :
spending time with your newborn is way more important than some s * * * * y talent show .
eleven years after mumsnet ' s birth , some now see roberts as a matriarchal cromwell leading a righteous army of middle - class mums into war . campaigns so far include a drive against the sexualisation of children ; improved care for women who miscarry ; and the perennial push for more family - friendly employers ( a mumsnet jobs club opens in the spring ) .
an extension of its recently - launched lifestyle campaign , the event will be hosted on sites such as mumsnet and britmums this week , as well as on the huffington post parenting .
there ' s a webchat going on over on mumsnet with simon stevens , chief executive of nhs england in case any of you might be interested in asking a question of him .
in 2007 , mumsnet , a popular online discussion forum for parents , was sued by gina ford for defamation , after some users wrote critical remarks about the childcare expert . the two parties reached an out - of - court settlement after mumsnet agreed to pay a contribution towards ms ford’s costs and pledged to prevent future “personal attacks” against her from appearing on their site .
thanks so much , i hope you feel we ' ve covered most of the main issues raised - sorry not to have more time but i hope to come back to mumsnet soon .
i imagine both were somewhat shocked by the outrage seemingly anodyne answers provoked . ' leave your hair alone and answer the damn questions , ' ordered one mumsnet - user to david cameron .
this book comprises carefully selected posts on the mumsnet forum organised into thematic chapters . it is great light reading , easy to dip into and good to pick up quick advice . . .
from jamie oliver to antony worrall thompson , we ' ve had the creme de la creme of chefs and cookery writers on mumsnet to chew the fat ( metaphorically , of course ) .
there is an amazing breadth of knowledge on mumsnet . most of us have a specialist subject or two . but most of us know a very little bit about everything else as well .
4 . i am not a father yet , but hopefully i soon will be . i don’t want a mumsnet and a dadsnet – i’d like mumsnet to be more even handed with both sexes , or if thats not possible just admit its a site for mums / women and say men / dads aren’t allowed . i’d much prefer the former of course . i want to do as much parenting as possible when i have children , and would hope i would be as welcome as any mother would be at mumsnet , come the time i need advice help and support .
while mumsnet has hit the headlines before , most notably in a legal battle with the childcare writer gina ford , it is only relatively recently that its members have started flexing their political muscle .
the internet is notoriously capricious , with a site being essential one moment and forgotten the next . but mumsnet ' s capacity to hold decision - makers to account shows no sign of fading .
lidl hopes its new yearly partnership with mumsnet will help build trust in the brand as it looks to boost its quality credentials and be seen as a destination supermarket , not just a discounter .
mumsnet has reset its users ' passwords after a series of attacks , one of which involved armed police being called out to the london home of the parenting site ' s co - founder .
additionally , she revealed that there had been an attempt to force mumsnet offline by swamping it with internet traffic , in what is known as a distributed denial of service ( ddos ) attack .
the one - year partnership started yesterday ( 7 september ) and has launched with a homepage takeover . it will also feature lidl uk branding across mumsnet food content pages , forums and newsletters .
mumsnet , following uk law on libel accusations , passed the letter on to narey and offered her the chance to delete the post or get in touch with buildteam to sort out the matter .
when politicians take part in mumsnet webchats , they ' re careful not to repeat gordon brown ' s mistake in dodging the biscuit question . here are some of the best answers share this on facebook
justine is now the mumsnet chief executive and last year she hosted the then prime minister gordon brown at its 10 - year anniversary bash . mr brown described it as a
national institution
.
but things had started to go badly when he was asked if he thought he had been an unlucky prime minister . ' not when i ' m sitting here at mumsnet ! ' he answered .
mumsnet chugged along for years with sensible forums on how to conceive , stop colic once you ' ve had the longed - for baby and generally be a middle - class parent without going mad .
mumsnet draws 25 , 000 postings and a million hits a day . apart from its popular chatrooms , it offers books and guides , and asks mumsnetters to test products and interview stars and politicians .
a recent mumsnet survey found major failings in the current postnatal care system – we want to change that . find out how you can get involved and make better postnatal care a reality for all .
but mumsnet is much more than a glorified listings site . the members ' forum has a reputation for supportive debate and has hosted online chats with public figures such as the conservative leader david cameron .
magazine , amanda said :
i visited mumsnet because i thought , ' oh , that sounds like a nice site where you can get handy tips on weaning your baby and helpful advice ' .
a large number of mumsnet people who ' d suffered a bereavement felt strongly that they had a right to complain to an organisation to which they pay a licence fee , and which almost boasts that it educates via its storylines ,
roberts says .
they wanted mumsnet to register the complaint . we didn ' t ask anyone to edit the storyline : that was the bbc ' s decision .
marketing week is the media partner of parenting website mumsnet’s third annual ‘mumstock’ event , which aims to highlight that while brands have access to a lot of data around parents , many still get it wrong .
ms roberts said that the second case occurred after a mumsnet user had engaged the dadsecurity twitter account and received back a message saying
prepare to be swatted
alongside a picture of a swat team .
earlier this year , another mumsnet user sparked a debate when she was given a wedding invite that said “adults only” and another user was left angry that her new husband’s mother invited herself on their honeymoon .
according to media reports two individuals , using the pseudonyms skohl and blackfairy7 , had posted criticisms of the surgeon on a number of mumsnet forum posts . the comments have since been deleted by web moderators .
mumsnet has not checked the qualifications of anyone posting here . if you need help urgently , please see our domestic violence webguide and / or relationships webguide , which can point you to expert advice and support .

last week a mumsnet poll found a distinct ‘authenticity deficit’ in all the main parties . if they wish to persuade women voters , they must change radically , co - founder and ceo justine roberts tells susanna rustin
i don’t see how the former is true if light - hearted critiques of mumsnet are not allowed , but more so , my video was not obscene , did not contain any personal attacks or break the law’ it did however raise some points , which i would honestly like mumsnet or mumsnetters opinions on . please don’t be too defensive ( or indulge in ‘personal attacks’ of course ) i think mumsnet is on the whole a force for good , and one my partner and i may be seriously grateful for if and when a baby comes – but i also think it is not perfect and should not censor criticism . such as
i must find out if cameron got this much grief last time he was on . he did a mumsnet live chat in 2006 , when he went back to work after paternity leave , and again in 2008 .
rival party leaders have been less reticent about their preferences when they appeared on mumsnet : tory leader david cameron likes oatcakes , while liberal democrat nick clegg prefers rich tea if they are dunked and hobnobs if not .

roberts is 43 years old , a former economist and sports correspondent , a liverpool supporter , and a mother of four . she has a strong sense of humour , an infectious laugh and a very clear idea of how mumsnet works . for those who choose to leave their prejudices at the door of
mumsnet towers
in north london , it ' s not all that difficult to understand its success as an online community and pressure group .
by and large , it seemed most sensible to ignore them , not least because we ' ve had our hands quite full with stuff that actually matters , like mumsnet ' s we believe you campaign to dispel rape myths .
mumsnet campaign : after 82 % of you told us you feel it ' s unacceptable for the nhs to allow commercial companies access to patients , we ' re campaigning for a ban on bounty sales reps in postnatal wards .

is there anything more terrifying than the invective of a mumsnet mum ? the sensible answer to this is , of course : yes , plenty , now stop asking such stupid questions . but there is nevertheless much circumstantial evidence to suggest that being attacked online by the stereotypical mumsnet mum ( and let ' s face it , the stereotype is an appealing one ; we all like a good caricature ) transforms a lot of hitherto happy people into the walking wounded .
which led to a slew of mumsnetters chucking lame insults and kind invitations to fuck off and die . but then the heavens opened and the celestial being that is mumsnet goddess justine something - or - other deigned to respond thusly –
some of you may have noticed that a group called fathers 4 justice has been saying some pretty unpleasant things about us over the last couple of weeks . in an ' advert ' which appeared first on facebook and then in friday march 16th ' s edition of the i , the group claims mumsnet
promotes gender hatred
, and labels
men and boys as rapists , paedophiles and wife beaters
. it calls on advertisers to suspend advertising on mumsnet .
ford has said she is happy to be criticised on her techniques , but has accused mumsnet of taking it too far and launching a personal attack on her . in a statement she said : ' any suggestion that i am trying to close down the mumsnet website is completely untrue . what has caused me so much upset has been the defamatory campaign waged against me as a person , in which i have been described in the most vile and disgusting terms . '
2 . 35pm : in the comments section below giantkatestacks says that i ' m wrong about some of the posters being activists . i ' m not a user of mumsnet so i ' m happy to take her word for it .
so treat yourself to another of those choccie - biscuits , gordon , and go back to combing your hair , dave . and be reassured - us mums aren ' t all as pedantic and kiddie - obsessed as the mumsnet crew .
mumsnet spoke to the national federation of retail newsagents ( nfrn ) about the campaign , but the nfrn was unable to sign the pledge on behalf of its members , so it is down to you to decide whether to sign up .
the image conjured by the attacks on mumsnet and its staff is one of men so sad , bitter and misguided that it can only be a parody . come on feminazis , own up : it was you really , wasn’t it ?
the something special and gigglebiz presenter came to mumsnet towers , charmed visiting children by singing and clowning around , and answered lots of your questions about his shows , receiving an mbe , makaton , bumper cars , biscuits and tons more .
thousands of women have used mumsnet to share heartbreaking stories illustrating where # miscarriagecare fell short . we ' re asking politicians to pledge to improve miscarriage care , based on our code of care , by the end of the next parliament .
i hope that isn’t too long , and that i don’t come across as a ‘trouble maker’ – as someone who may be needing mumsnet or similar soon , i’m very interested in asking these questions and raising these criticisms , hopefully constructively .
the abi said it was was keen to gain insight from mumsnet users about how online pension information could make a difference as parents are particularly likely to take career breaks , return to lower paid work and have gaps in their pension saving .
the biscuitgate row started when mr brown answered questions on the mumsnet website on a wide range of issues , including his recent eye problem . but it all went wrong when he repeatedly failed to respond to enquiries from parents about his favourite biscuit .
but finally at midday yesterday , he answered on his twitter web page , writing : ' i missed mumsnet question about biscuits : the answer is absolutely anything with a bit of chocolate on it , but trying v hard to cut down . '
she and her mumsnet co - founder , carrie longton , were recently proclaimed by radio 4 ' s woman ' s hour to be the joint - seventh most - powerful women in the country . but how did this all come to be ?
waitrose stock a very limited selection of men ' s lifestyle magazines , and in support of mumsnet ' s campaign , on the occasion that the publications feature covers that could be considered controversial , we would ask that the publisher polybag or wrap them .
although we do not currently have any plans to make further changes to the way we display these titles , the feedback from the mumsnet survey is valuable to us as we try to strike the right balance in meeting the needs of all our customers .
i won’t post it again . you can find it on youtube if you search ‘mumsnet no menz’ i don’t think it was offensive . it was critical of mumsnet in a humorous way… is that why i was banned ? i looked in the rules and can find only ‘talk – all human life is there’ and “our policy is to keep intervention to a minimum and let the conversation flow . having said that , we will remove postings that are obscene , contain personal attacks or break the law . ”
3 . as my video said i do think its strange or inappropriate that there is a feminist section ( and quote a dogmatic one if i may add ) on mumsnet , where so many regulars of that section proudly claim not to be parents .
mumsnet has banned mention of ford on the site and mediation is due to take place later this month . should it fail , ford ' s solicitors have given notice of their intention to begin high court proceedings and the site could be closed down .
we are delighted to announce that sainsburys , morrisons , waitrose , bp * , asda , the co - operative group and tesco have all pledged to support mumsnet ' s campaign to keep lad mags out of children ' s view in all their stores .
last year , the site extended its reach with gransnet ; there is talk of mumsnet tv ; and she won ' t rule out the possibility , one day , of launching a dadsnet , too :
never say never . anything is possible .
as the controversial author prepares for the latest stage in her legal battle with mumsnet , the parents ' forum she is suing after allegedly insulting messages were posted on its internet site , a new attack comes from a channel 5 documentary to be broadcast tomorrow .
on the site , it trumpets positive reviews , including one which called it ' the daddy of parenting sites ' . in some circles , it would be preferable to admit you feed your child cola in its bottle rather than admit to an uneasiness about mumsnet .
following our survey , which found nine out of ten parents wanted lads ' mags out of sight , mumsnet called on major news retailers to take action to ensure that magazines with sexual images on the cover were kept out of children ' s sight in stores .
mumsnet has a long - standing relationship with brands in the food and drink space , including asda , which has traditionally positioned itself as the grocer for ' mums ' . the retailer has a panel of 5 , 000 women in its ' mumdex ' community .
“my life was put on hold until i had finished the very last word . ” find out what mumsnet book bloggers think about our june book of the month and join us in reading little fires everywhere before the webchat with author celeste ng on 26 june .
was she being totally honest when she describes mumsnet as a place where ‘the line is drawn’ only at folks whose sole purpose seems to be to wind up others ? it seems to this page where that line is depends a lot on what genitalia you possess .
she does acknowledge that the size of mumsnet these days does
magnify
negative reactions .
you can get 200 replies disagreeing with what you ' ve said . we just remind people that it ' s not a group of people out to get you .
sainsburys and morrisons , which have operated similar policies for some years , have told mumsnet that it does not affect the sales figures of these titles , and i feel sure that such a policy would pay off for your business because of the goodwill you would receive .
by this point , the thread on mumsnet had grown to include other posters claiming to have had bad experiences with the building firm . some of them decided to remove the posts in response to the legal threats from buildteam , but narey wanted to keep hers up .
that promise last week began to look a little threadbare . vincent put out a statement that said :
i had hoped that after david cameron came to visit me earlier this year following our exchange on mumsnet he would have done more to protect families like ours .
we know that this is an important issue for many of our shoppers and this is why we were one of the first retailers to introduce modesty covers back in 2006 . we hope that other retailers follow sainsbury ' s lead in signing up to mumsnet ' s campaign .
but sadly for f4w , terfs , and # mumsnet trads , it turns out that the civil service is considerably smarter than a ploy that wouldn ' t have fooled a seven year old , and so the terfy cunning plan utterly failed . . . 11 / n urltoken
any parents bottle feeding their little one , which bottles have you liked ? i’m just not so sure we are using the right ones with tommee tippee . she seems to get so much wind . # mummybloggers # pbloggers # babyadvice # babylife # mumlife # mumsnet # mumsuk
chief executive justine roberts said : ‘mumsnet is the mothership when it comes to sharing relatable parenting experiences with the potential for lots of swearing , so this is right up our alley ; each of the episodes outlines a situation that could have come straight from our forums . ’
but mumsnet does much more than quiz politicians . funded entirely by advertising , it functions as a resource for information on pregnancy and childcare , offers product reviews and even runs a book club . tonight it is hosting a chat session with the award - winning author rose tremain .
some political pundits have described next year ' s big political battle as the mumsnet election , claiming that whoever wins the poll will have won over the 850 , 000 mothers who regularly use the parenting website – just as the worcester woman was the symbolic swing voter in 1997 .
excuse my language . . . but fuck you to all the @ mumsnettowers # mumsnet haters who can’t see that tom and dustin are obviously devoted to each other , and have shown nothing an unwavering commitment to providing their son with an upbringing that most could only dream of .
as much as we love norks – with their many uses – here at mumsnet , we think they ' re really not news . so , following on from this discussion we ' re very pleased to announce that we ' re getting behind the no more page 3 campaign .
yes , but look ,
mumsnet co - founder justine roberts tells me ,
for every critical post , there is a positive one . it ' s free speech , ultimately . everyone is welcome to voice their opinion , and it is mostly pretty balanced .
roberts is a city analyst turned football and cricket writer , and mumsnet was also her attempt to find a flexible job that would be rewarding , but would leave her free to see her children and
not have to squirm if i wanted to pop into a school event
.
so no one is recommending the mumsnet standard response of
fuck off to the far end of fuck off land and when you get there fuck off some more
? i am still waiting for someone to be rude about my parenting choices so i can say it . . .
but in april , the decision was made for her , in a very peculiar way . mumsnet received a warning from google : a takedown request had been made under the american digital millennium copyright act ( dmca ) , alleging that copyrighted material was posted without a licence on the thread .
the campaigns we feature are not actively endorsed or supported by mumsnet , but are about issues which we think may be of interest to some mumsnetters - recent campaigns range from maternal health in the developing world , to support for lone parents , to a campaign to promote responsible dog ownership .
recently , mumsnet triumphed in a battle over a £1 . 25m billboard campaign that declared , in one of a series of deliberately provocative statements intended to demonstrate the power of outdoor advertising , that
career women make bad mothers
( the poster was withdrawn ) . it has also tussled with gina ford , the parenting guru , who complained about insults posted about her on mumsnet forums ( the case was settled out of court ) . and most recently , it has challenged eastenders over a storyline in which a mother who loses her baby to a cot death steals another child .
created seven years ago by two new mothers , mumsnet has become an ' internet phenomenon ' , according to the sunday telegraph , and ' the country ' s most popular meeting point for parents ' , according to the times , and it is widely regarded as the uk ' s leading online parenting community . it has 100 , 000 registered uses , and 250 , 000 monthly users , and its members are loyal , active and passionate about the site . fans of mumsnet include india knight , prime minister gordon brown , the chief rabbi jonathan sacks , to name but a few .

google is aware of cases like narey’s , and is looking at how to improve fraud detection , but there’s a limit to what it can do in general . the scale is too large for it to take the sort of personal approach that automattic did with hotham’s case , and ultimately the law doesn’t allow for it to hit back against fraudulent claims without some involvement of the accused – which , technically , was mumsnet , not narey . and while mumsnet was offered the chance to file a counterclaim , the forum couldn’t , because it too couldn’t be certain the claim actually was fraudulent .
note : this topic is for discussing pushchairs . to find out which pushchairs have won mumsnet best , read our lightweight stroller reviews . if you want to buy and sell pushchairs , please use our for sale / wanted boards . please feel free to report buying and selling in this topic .
charities working with disabled children have thanked mumsnet for the publicity it has generated . other commentators , however , while sympathetic to celyn ' s family , are less than enchanted with the sight of the mummy - warriors marching forth yet again , exercising an influence they believe is disproportionate to their numbers .
you see , the terfs were well aware of the survey , what with talking about it on both gc reddit and # mumsnet / pol / - lite board , and the survey itself ( linked in the screenshot ) is pretty clear as to what it was about . . . 9 / n urltoken

media law is hammered into journalists during their on - job training or university education . the general public are not afforded the same luxury . the question is , should online forums like mumsnet do more to protect their users from legal repercussions or would this impact on site engagement and ultimately damage the community ?
thousands of women have used mumsnet to share heartbreaking stories of miscarriage care falling short . like everyone else , we believe the nhs should provide effective , responsive care and treatment to the one in five pregnancies that ends in miscarriage , but w hile some trusts provide great care , unfortunately , others do not .
certainly , mumsnet attracts an extraordinary degree of venom . it has been labelled censorious , moralising , smug , vicious , bullying and sanctimonious , and accused of having members who are rude , dogmatic and as
thick as mincemeat
who remain immersed for hours in the subjects of weaning , nappies and nipples .
ever since politicians began courting the site as a way in to new media , murmurs of complaint on the blogosphere have grown into a roar .
what the hell does mumsnet think it is ?
seems to be the gist . and how does it manage to pull the strings of publicity so effectively ?
buildteam disputes her account . in a letter sent to mumsnet , which the site passed on to narey , the builders complained that the comments were defamatory . they say it is “untrue” that the ceiling fell down due to an issue with plumbing , and cited a total of 11 statements they claimed were defamatory .
mumsnet deleted the post , and asked google to reinstate the thread , but a month later , they received final word from the search firm : “‘google has decided not to take action based on our policies concerning content removal and reinstatement’ which ( it turned out ) meant that they had delisted the entire thread” .
we ' re harnessing the might of mumsnet and putting it behind causes close to your heart . they range from this is my child and let girls be girls , to our miscarriage care and we believe you campaigns , and our campaign to change how britain ' s libel laws affect online publishers like us .
one imagines that she could sell mumsnet and make a fortune , but she insists that this is unlikely . she says she cares too much about the site , its collective voice , and fears that selling out might change everything it has come to stand for . so instead , she continues to grow it .
i do tour the country . in particular i do
cameron direct
public meetings which are just q and a and no speeches . i ' ve done 52 of these and have more planned . perhaps we could do one in association with mumsnet . talking to the team about it now . . . .
whoever sent the takedown request , mumsnet was forced to make a choice : either leave the post up , and accept being delisted ; fight the delisting and open themselves up to the same legal threats made against google ; or delete the post themselves , and ask the post to be relisted on the search engine .
