You can change the administrator or monitor passwords and define role-based users in the Configure > Security > User Permissions page.Admin - The administrator user has full privileges: for example, as an administrator you can set and modify configuration settings, add and delete users, restart the optimization service, reboot the Steelhead appliance, and create and view performance and system reports. Monitor - A monitor user can view reports, user logs, and change their password. A monitor user cannot make configuration changes, modify private keys, view logs, or manage cryptographic modules in the system. You can also create users, assign passwords to the user, and assign varying configuration roles to the user. A user role determines whether the user has permission to:Read-only - With read-only privileges you can view current configuration settings but you cannot change them. Read/Write - With read and write privileges you can view settings and make configuration changes for a feature. Deny - With deny privileges you cannot view settings or save configuration changes for a feature. As an example, you might have user Jane who can make configuration changes to QoS and SSL whereas user John can only view these configuration settings; and finally, user Joe cannot view, change, or save the settings for these features.Available menu items reflect the privileges of the user: for example, any menu items that a user does not have permission to use are unavailable. When a user selects an unavailable link, the User Permissions page appears.Important: The Optimization Services role in RiOS v6.1 and later includes permission to access High-Speed TCP (HS-TCP). Consequently, upgrading to RiOS v6.1 or later causes all role-based users with permission for the High-Speed TCP (HS-TCP) role to lose their access. The Administrator must manually reassign those users who require HS-TCP access with permission for the Optimization Services (GUI) or the Acceleration services (CLI) role. Alternatively, the administrator can create a custom role for the HS-TCP users.
Enable Account - Select to enable or clear to disable the administrator or monitor account. Change Password - Enables password protection.RiOS v8.0 and later includes an account control feature that allows you to select a password policy for more security. When you enable account control on the Configure > Security > Password Policy page, a user must use a password.When a user has a null password to start with, the administrator can still set the user password with account control enabled. However, once the user or administrator changes the password, it cannot be reset to null as long as account control is enabled. Password - Specify a password in the text box. Password Confirm - Retype the new administrator password.
Configures host and network interface settings, including DNS cache settings and hardware assist rules. Configures TCP traffic for optimization and how to optimize traffic by setting in-path rules. This role includes WAN visibility to preserve TCP/IP address or port information.For details about WAN visibility, see the Steelhead Appliance Deployment Guide. Configures enhanced HTTP optimization settings: URL learning, Parse and Prefetch, Object Prefetch Table, keep-alive, insert cookie, file extensions to prefetch, and the ability to set up HTTP optimization for a specific server subnet. Oracle Forms Optimization Replication Optimization Riverbed Services Platform (RSP) Configures functionality into a virtualized environment on the client Steelhead appliance. The functionality can include third-party packages such as a firewall security package, a streaming video server, or a package that provides core networking services (for example, DNS and DHCP). This role includes permission to install VMware tools and add subnet side rules. For details, see the RSP User’s Guide. Granite Branch Storage Service Configures branch storage services on Granite Edge appliances (the branch storage services are only available on a Steelhead EX appliance). Configures security settings, including RADIUS and TACACS authentication settings and the secure vault password. Customizes TCP dump settings and allows use of the Shark function for detailed packet analysis through Cascade Pilot. Select the check box next to the name and click Remove Selected.
4. Click Save to save your settings permanently.Note: RiOS ignores the RBM user roles for SCA features. RiOS allows RBM users with DENY permissions in all roles access to SCA Management Console pages and GUI commands.

base implementation of Tree and TreeAdaptor
@brief A generic tree implementation with no payload. You must subclass to actually have any user data. ANTLR v3 uses a list of children approach instead of the child-sibling approach in v2. A flat tree (a list) is an empty node whose children represent the list. An empty, but non-null node is called "nil".
| def google.appengine._internal.antlr3.tree.BaseTree.__init__ | ( | self, | |
node = None |
|||
| ) |
Create a new node from an existing node does nothing for BaseTree as there are no fields other than the children list, which cannot be copied as the children are not considered part of this node.
| def google.appengine._internal.antlr3.tree.BaseTree.addChild | ( | self, | |
| childTree | |||
| ) |
Add t as child of this node. Warning: if t has no children, but child does and child isNil then this routine moves children to t via t.children = child.children; i.e., without copying the array.
| def google.appengine._internal.antlr3.tree.BaseTree.addChildren | ( | self, | |

This is a somewhat longer PR (600 lines). I think these "shapes" are finally getting into good shape. It seems to be non-trivial to get this right. Thanks Scott for all these iterated efforts. I invite people with experience in formalisation of category theory to review this. @Reid Barton @Floris van Doorn @Jesse Michael Han @Jakob von Raumer
In particular if people could look at the tutorial for examples of intended usage that would be great.

Covariance Estimation¶
Introduction¶
One way to assess the quality of the solution returned by a non-linear least squares solver is to analyze the covariance of the solution.
Let us consider the non-linear regression problem
i.e., the observation \(y\) is a random non-linear function of the independent variable \(x\) with mean \(f(x)\) and identity covariance. Then the maximum likelihood estimate of \(x\) given observations \(y\) is the solution to the non-linear least squares problem:
And the covariance of \(x^*\) is given by
Here \(J(x^*)\) is the Jacobian of \(f\) at \(x^*\). The above formula assumes that \(J(x^*)\) has full column rank.
If \(J(x^*)\) is rank deficient, then the covariance matrix \(C(x^*)\) is also rank deficient and is given by the Moore-Penrose pseudo inverse.
Note that in the above, we assumed that the covariance matrix for \(y\) was identity. This is an important assumption. If this is not the case and we have
Where \(S\) is a positive semi-definite matrix denoting the covariance of \(y\), then the maximum likelihood problem to be solved is
and the corresponding covariance estimate of \(x^*\) is given by
So, if it is the case that the observations being fitted to have a covariance matrix not equal to identity, then it is the user’s responsibility that the corresponding cost functions are correctly scaled, e.g. in the above case the cost function for this problem should evaluate \(S^{-1/2} f(x)\) instead of just \(f(x)\), where \(S^{-1/2}\) is the inverse square root of the covariance matrix \(S\).
Gauge Invariance¶
In structure from motion (3D reconstruction) problems, the reconstruction is ambiguous upto a similarity transform. This is known as a Gauge Ambiguity. Handling Gauges correctly requires the use of SVD or custom inversion algorithms. For small problems the user can use the dense algorithm. For more details see the work of Kanatani & Morris [KanataniMorris].
Covariance
¶
Covariance
allows the user to evaluate the covariance for a
non-linear least squares problem and provides random access to its
blocks. The computation assumes that the cost functions compute
residuals such that their covariance is identity.
Since the computation of the covariance matrix requires computing the
inverse of a potentially large matrix, this can involve a rather large
amount of time and memory. However, it is usually the case that the
user is only interested in a small part of the covariance
matrix. Quite often just the block diagonal. Covariance
allows the user to specify the parts of the covariance matrix that she
is interested in and then uses this information to only compute and
store those parts of the covariance matrix.
Rank of the Jacobian¶
As we noted above, if the Jacobian is rank deficient, then the inverse of \(J'J\) is not defined and instead a pseudo inverse needs to be computed.
The rank deficiency in \(J\) can be structural – columns which are always known to be zero or numerical – depending on the exact values in the Jacobian.
Structural rank deficiency occurs when the problem contains parameter blocks that are constant. This class correctly handles structural rank deficiency like that.
Numerical rank deficiency, where the rank of the matrix cannot be predicted by its sparsity structure and requires looking at its numerical values is more complicated. Here again there are two cases.
- The rank deficiency arises from overparameterization. e.g., a four dimensional quaternion used to parameterize \(SO(3)\), which is a three dimensional manifold. In cases like this, the user should use an appropriate
LocalParameterization
. Not only will this lead to better numerical behaviour of the Solver, it will also expose the rank deficiency to theCovariance
object so that it can handle it correctly.- More general numerical rank deficiency in the Jacobian requires the computation of the so called Singular Value Decomposition (SVD) of \(J'J\). We do not know how to do this for large sparse matrices efficiently. For small and moderate sized problems this is done using dense linear algebra.

otherwise. Note thatEIGEN_SPARSE
is always available.
-
CovarianceAlgorithmType
Covariance::Options::
algorithm_type
¶ Default:
SPARSE_QR
Ceres supports two different algorithms for covariance estimation, which represent different tradeoffs in speed, accuracy and reliability.
SPARSE_QR
uses the sparse QR factorization algorithm to compute the decomposition\[\begin{split}QR &= J\\ \left(J^\top J\right)^{-1} &= \left(R^\top R\right)^{-1}\end{split}\]The speed of this algorithm depends on the sparse linear algebra library being used.
Eigen
’s sparse QR factorization is a moderately fast algorithm suitable for small to medium sized matrices. For best performance we recommend usingSuiteSparseQR
which is enabled by settingCovaraince::Options::sparse_linear_algebra_library_type
toSUITE_SPARSE
.Neither
SPARSE_QR
cannot compute the covariance if the Jacobian is rank deficient.DENSE_SVD
usesEigen
’sJacobiSVD
to perform the computations. It computes the singular value decomposition\[U S V^\top = J\]and then uses it to compute the pseudo inverse of J’J as
\[(J'J)^{\dagger} = V S^{\dagger} V^\top\]It is an accurate but slow method and should only be used for small to moderate sized problems. It can handle full-rank as well as rank deficient Jacobians.
-
int
Covariance::Options::
min_reciprocal_condition_number
¶ Default: \(10^{-14}\)
If the Jacobian matrix is near singular, then inverting \(J'J\) will result in unreliable results, e.g, if
\[\begin{split}J = \begin{bmatrix} 1.0& 1.0 \\ 1.0& 1.0000001 \end{bmatrix}\end{split}\]which is essentially a rank deficient matrix, we have
\[\begin{split}(J'J)^{-1} = \begin{bmatrix} 2.0471e+14& -2.0471e+14 \\ -2.0471e+14 2.0471e+14 \end{bmatrix}\end{split}\]This is not a useful result. Therefore, by default
Covariance::Compute()
will returnfalse
if a rank deficient Jacobian is encountered. How rank deficiency is detected depends on the algorithm being used.DENSE_SVD
\[\frac{\sigma_{\text{min}}}{\sigma_{\text{max}}} < \sqrt{\text{min_reciprocal_condition_number}}\]where \(\sigma_{\text{min}}\) and \(\sigma_{\text{max}}\) are the minimum and maxiumum singular values of \(J\) respectively.
SPARSE_QR
\[\operatorname{rank}(J) < \operatorname{num\_col}(J)\]Here \(\operatorname{rank}(J)\) is the estimate of the rank of \(J\) returned by the sparse QR factorization algorithm. It is a fairly reliable indication of rank deficiency.
-
int
Covariance::Options::
null_space_rank
¶ When using
DENSE_SVD
, the user has more control in dealing with singular and near singular covariance matrices.As mentioned above, when the covariance matrix is near singular, instead of computing the inverse of \(J'J\), the Moore-Penrose pseudoinverse of \(J'J\) should be computed.
If \(J'J\) has the eigen decomposition \((\lambda_i, e_i)\), where \(\lambda_i\) is the \(i^\textrm{th}\) eigenvalue and \(e_i\) is the corresponding eigenvector, then the inverse of \(J'J\) is
\[(J'J)^{-1} = \sum_i \frac{1}{\lambda_i} e_i e_i'\]and computing the pseudo inverse involves dropping terms from this sum that correspond to small eigenvalues.
How terms are dropped is controlled by min_reciprocal_condition_number and null_space_rank.
If null_space_rank is non-negative, then the smallest null_space_rank eigenvalue/eigenvectors are dropped irrespective of the magnitude of \(\lambda_i\). If the ratio of the smallest non-zero eigenvalue to the largest eigenvalue in the truncated matrix is still below min_reciprocal_condition_number, then the Covariance::Compute() will fail and return false.
Setting null_space_rank = -1 drops all terms for which
\[\frac{\lambda_i}{\lambda_{\textrm{max}}} < \textrm{min_reciprocal_condition_number}\]This option has no effect on
SPARSE_QR
.

bool
Covariance::Options::
apply_loss_function
¶ Default: true
Even though the residual blocks in the problem may contain loss functions, setting
apply_loss_function
to false will turn off the application of the loss function to the output of the cost function and in turn its effect on the covariance.

Covariance::
Compute
(const vector<pair<const double *, const double *>> &covariance_blocks, Problem *problem)¶ Compute a part of the covariance matrix.
The vector
covariance_blocks
, indexes into the covariance matrix block-wise using pairs of parameter blocks. This allows the covariance estimation algorithm to only compute and store these blocks.Since the covariance matrix is symmetric, if the user passes
<block1, block2>
, thenGetCovarianceBlock
can be called withblock1
,block2
as well asblock2
,block1
.covariance_blocks
cannot contain duplicates. Bad things will happen if they do.Note that the list of
covariance_blocks
is only used to determine what parts of the covariance matrix are computed. The full Jacobian is used to do the computation, i.e. they do not have an impact on what part of the Jacobian is used for computation.The return value indicates the success or failure of the covariance computation. Please see the documentation for
Covariance::Options
for more on the conditions under which this function returnsfalse

(const double *parameter_block1, const double *parameter_block2, double *covariance_block) const¶ Return the block of the cross-covariance matrix corresponding to
parameter_block1
andparameter_block2
. Returns cross-covariance in the tangent space if a local parameterization is associated with either parameter block; else returns cross-covariance in the ambient space.Compute must be called before the first call to

marpa_r_current_earleme (Marpa_Recognizer r)Return value: If input has started, the current earleme. If input has not started, −1. Always succeeds.
In the default, token-stream model, Earley set ID and earleme are always equal, but this is not the case in other input models. (The ID of an Earley set ID is also called its ordinal.) If there is no Earley set whose ID is set_id,
marpa_r_earleme()
fails. If set_id was negative, the error code is set toMARPA_ERR_INVALID_LOCATION
. If set_id is greater than the ordinal of the latest Earley set, the error code is set toMARPA_ERR_NO_EARLEY_SET_AT_LOCATION
.At this writing, there is no method for the inverse operation (conversion of an earleme to an Earley set ID). One consideration in writing such a method is that not all earlemes correspond to Earley sets. Applications that want to map earlemes to Earley sets will have no trouble if they are using the standard input model — the Earley set ID is always exactly equal to the earleme in that model. For other applications that want an earleme-to-ID mapping, the most general method is create an ID-to-earleme array using the
marpa_r_earleme()
method and invert it.Return value: On success, the earleme corresponding to Earley set set_id. On failure, −2.
Returns the integer value of earley_set. For more details, see the description of
marpa_r_earley_set_values()
.Return value: On success, the value of earley_set. On failure, −2.
If p_value is non-zero, sets the location pointed to by p_value to the integer value of the Earley set. Similarly, if p_pvalue is non-zero, sets the location pointed to by p_pvalue to the pointer value of the Earley set.
The “value” and “pointer” of an Earley set are an arbitrary integer and an arbitrary pointer that the application can use for its own purposes. In character-per-earleme input models, for example, the integer can be the codepoint of the current character. In a traditional token-per-earleme input model, they could be used to indicate the string value of the token – the pointer could point to the start of the string, and the integer could indicate its length.
The Earley set value and pointer can be set using the
marpa_r_latest_earley_set_values_set()
method. The Earley set integer value defaults to −1, and the pointer value defaults toNULL
.Return value: On success, returns a non-negative integer. On failure, returns −2.
unsigned int
marpa_r_furthest_earleme (Marpa_Recognizer r)Return value: On success, the furthest earleme. Always succeeds.
This method returns the Earley set ID (ordinal) of the latest Earley set. Applications that want the value of the latest earleme can convert this value using the
marpa_r_earleme()
method.Return value: On success, the ID of the latest Earley set. Always succeeds.
Sets the integer value of the latest Earley set. For more details, see the description of
marpa_r_latest_earley_set_values_set()
.Return value: On success, the new value of earley_set. On failure, −2.
Sets the integer and pointer value of the latest Earley set. For more about the “integer value” and “pointer value” of an Earley set, see the description of the
marpa_r_earley_set_values()
method.Return value: On success, returns a non-negative integer. On failure, returns −2.


Hen commonly refers to a female animal: a chicken, other gallinaceous bird, any type of bird in general, or a lobster. a woman. It is also a slang term for Hen or Hens may also refer to. Answer. Answer: A hen is a female chicken. And a rooster is a male chicken; the term “chicken” is used for the species as a whole.  Other terms are: 'Biddy:' a newly hatched chicken. 'Capon:' a castrated or neutered male chicken. 1a : a female chicken especially over a year old broadly : a female bird. b : the female of various mostly aquatic animals such as lobsters or fish woman especially : a fussy middle-aged woman.
Hen Buskerud, a village in Ringerike municipality Hen Møre og Romsdal, a former municipality now in Rauma municipality Hen Church Hen: A female chicken. Nest Egg: Literally, a china or wooden egg placed into the nest to encourage laying; figuratively, something set aside as security. Learn more about egg production in your chicken coop. Point-of-lay Pullet: A young female, just about to lay, near 5 months old. Laying hens can safely be eaten just like their non-laying counterparts. Depending on their age, the meat may be tougher in texture and more gamey in taste. So the real answer to this question is dependent on your taste. Meat from laying hens is generally thought to be gamey.
Hazel Brook or Hen, a stream in Bristol, England Hen Cliff, on the Isle of Purbeck, Dorset, England HEN, station code for Hendon railway station, England. Do we eat male chickens?  Rooster meat is a little tougher and more stringy but is perfectly fine. It's most expensive for farms to raise roosters for meat though. Male chicks are killed for two reasons: they cannot lay eggs and they are not suitable for chicken-meat production. ... Layer hens are bred to produce eggs whereas meat chickens are bred to grow large breast muscle and legs.
Hen Island (disambiguation) Hen and Chicken Islands Henan, a province of China (Guobiao abbreviation HEN) In this page you can discover 13 synonyms, antonyms, idiomatic expressions, and related words for hen, like: female chicken, chicken, bird, fowl, brooder, stag-party, stag, setting hen, Fetsch, Gapel and biddy. Most hens will lay their first egg around 18 weeks of age and then lay an egg almost daily thereafter. In their first year, you can expect up to 250 eggs from high-producing, well-fed backyard chickens. So the simplest rule in sexing chicks by down color is to remember males have lighter heads, sometimes with a white or yellow spot, and females have darker down color often with a black or brown spot or stripes on their heads or with darker stripes on their backs.  Hen = adult female chicken. Cock/Rooster = adult male chicken. Capon = castracted male chicken (requires surgery since the reproductive organs are internal) Apart from the terms hen and rooster, there are also the terms cockerels and pullets. While these terms refer to different birds, they are all chickens.  A cockerel is a young rooster who is less than one year of age.
Hen (name), a given name and surname Hen (pronoun), a Swedish gender-neutral pronoun Symphony No. 83 (Haydn), nicknamed The Hen. Why Are Male Chickens Not Suitable for Meat? It's not so much that male chickens are not suitable for meat. It's more so that it's more economical for farms and poultry breeders to produce and sell female chickens for meat production. The chicken you see in supermarkets comes from “Broiler” chickens. Male chicks are killed for two reasons: they cannot lay eggs and they are not suitable for chicken-meat production. ... Layer hens are bred to produce eggs whereas meat chickens are bred to grow large breast muscle and legs. Originally Answered: Where does the word chicken come from? Hens' vocal sound in normal situation is Chick a dip then chick again n so on. Thus the domestic bird had been named chicken.
Hen (manga), a 1988 manga created by Hiroya Oku HEN, UCI team code for Hengxiang Cycling Team HEN, abbreviation for Hallmark Entertainment Network Hen., an abbreviation of the given name Henry. The hen does not completely change into a rooster, however. This transition is limited to making the bird phenotypically male, meaning that although the hen will develop physical characteristics that will make her look male, she will remain genetically female. One method that does work on some breeds is wing sexing. Wing sexing can only be done within the first 48 hours of when the chick hatches. Hens' wing feathers are two different lengths while roosters' are the same length. So in the photos above, the chick on the left is a female, while the chick on the right is a male. Take a sharp knife, grab his head, stretch him out, and slice the neck right through the spine just under the bill. Do it quick in one fast, deliberate motion.  He'll flop and bleed out in just a couple minutes.


Prefetching code insertion has limitless possibilities because it is loading memory before it executes at any stage of your code. Computing every possibility would take an exceptional amount of time, and running every possible code would take even longer. We are trying to make this process easier by trying to define heuristics that might be found within different types of code.
We can model this with the use of prefetching pragmas which will be simulated as prefetches in the multi-core system.
Pseudocode example of prefetch pragmas:
Void memAccess(int* array) {
# Prefetch array[0:100]
For (int i = 0; i < len(array); i ++ ) {
array[i] = array[i] + 1;
}
}


cbgb
Download
Note: pre-alpha, is rebuilt often, and is probably not ready for production use, unless you like to live on the edge
Start
Download. Unzip the binary. On non-windows, make cbgb executable.
Check out command line options: $ ./cbgb -h
.
By default cbgb will make a tmp folder "./tmp" to store data wherever you run it from, I prefer to make an explicit folder somewhere to store the data.
For Example:
$ chmod 755 cbgb $ mkdir ~/cbgb-data $ ./cbgb -data="~/cbgb-data/"Note: the default ports conflict with memcached, Membase, and Couchbase, so if you want to connect to cbgb, kill those first. You can also run it on other ports, however, we haven't tested our Couchbase SDK's against that scenario yet.
Admin
Connect your browser to http://localhost:8091/
to create buckets, design documents and map-reduce views.
REST
While the Couchbase SDK's and binary protocols are faster, cbgb can also use REST for CRUD and Index Querying (Views). REST operations are done on port 8092 by default. View Querying follows the Couchbase syntax.
Note: Currently only GET's are implemented (for Documents).
| VERB | Operation | Example |
|---|---|---|
| GET | Retrieve Item |
curl -X GET http://localhost:8092/{bucket}/{key} curl -X GET http://localhost:8092/default/testkey |
| GET | Retrieve All Documents |
curl -X GET http://localhost:8092/{bucket}/_all_docs curl -X GET http://localhost:8092/default/_all_docs |
SDK's
cbgb uses Couchbase SDK's for operations.
You can find them with the Couchbase Develop page. Simply follow the instructions as if you were connecting to Couchbase itself.
Note: The Java SDK automatically reconnects when there is an operation and cbgb has passivated a bucket. Other clients may not, in those cases you have to wrap the SDK with a Couchbase::Error::Network rescue/catch handler (whatever is appropriate for the language) and reconnect before retrying the operation.

THE LONG KISS GOODNIGHT A film review by Steve Rhodes Copyright 1996 Steve Rhodes
RATING (0 TO ****): * 1/2
"Life is pain. Get used to it!"  Geena Davis plays mom Samantha Caine and once paid CIA domestic assassin Charly Baltimore.
The creative team of director Renny Harlin and his wife Davis, who brought the world that bomb known as CUTTROAT ISLAND, this year give us Davis as a female Steven Seagal in THE LONG KISS GOODNIGHT. Although Davis is talented, Harlin has exactly one decent film to his name, DIE HARD 2, and a string of ridiculous ones, including such turkeys as NIGHTMARE ON ELM STREET 4 and THE ADVENTURES OF FORD FAIRLANE.

If you saw CHAIN REACTION this year and liked it, you will get to relive all of the explosions and fights. Davis gets to put on a pair of convenient ice skates to outrun a speeding car, but other than that, you've seen all of the stunts before. Harlin does manage to spend all of his backers' money in one explosion after another proving that his profligate excesses are rarely rivaled. Oh well, the dream of every producer is that escapism like this will sell lots of tickets and popcorn.
Mild mannered Samantha has been trying for eight years to find out who she is and who is her daughter Caitlin's (Yvonne Zima) father. Having run out of funds to hire real detectives, Samantha scrapes the bottom of the barrel employing Mitch Henessey (Samuel L. Jackson), who is a combination PI and scam artist.
One day she is in a car accident that starts her transformation back into a paid killer for the government. Henessey is shocked by her metamorphosis, especially the degeneration of her language, saying, "Now, you go into a bar, and the sailors start running out."
 Whew.
Character development along the way consists of lots of stick figure CIA agents and bad guys working together to screw the taxpayers out of their money. Patrick Malahide plays CIA operative Perkins. Of course, the President (G. D. Spradlin) has dirty hands too.  My favorite role of his was as the corrupt Senator Pat Geary in THE GODFATHER: PART II.
Unless you need an action fix, there are only two reasons to see THE LONG KISS GOODNIGHT. First, there is good chemistry between Davis and Jackson, who both have a lot of fun making the picture. Second, the dialog by Shane Black has several funny lines. My favorite is when Henessey explains on Larry King Live that, "I am always frank and earnest with women. In Chicago I'm Frank, and in New York I'm Ernest." Most of the humorous lines are unprintable forms of double-entendre.
THE LONG KISS GOODNIGHT runs a full 2:00. By half way through, I got tired of seeing yet another blast and wished editor William Goldenberg had exercised more control. The film is rated R for excessive violence too often reminiscent of a horror flick and constant bad language used mainly to shock. The film has no sex or nudity. Teenagers used to a diet of heavy movie violence will probably like the film, but I don't see why anyone would bother. THE LONG KISS GOODNIGHT gets a thumbs down from me and a * 1/2.
**** = One of the top few films of this or any year. A must see film. *** = Excellent show. Look for it. ** = Average movie. Kind of enjoyable. * = Poor show.  Totally unbearable.

The report
highlights a dramatic increase in the take-up of A level and further mathematics, and shows that the youngest children are doing better. GCSE and A-level results continue to rise as a result of the sustained efforts of teachers and students.
But the report finds 3 key areas in primary and secondary mathematics in schools in England, which need to be improved:
-
firstly, not enough is being done to help pupils catch up who fall behind early; the 10% who do not reach the expected standard at age 7 doubles to 20% by age 11, and nearly doubles again by age 16
-
secondly, inspection evidence shows that pupils in lower ability sets and younger pupils received the weakest teaching; inspectors regularly saw outstanding and satisfactory teaching, and sometimes inadequate too, within an individual school
-
thirdly, lots of the brightest pupils do not fulfil their potential when they get to secondary school; 37,000 of the highest attaining primary school pupils got no better than a grade C at GCSE in mathematics last year; schools which routinely enter students early for GCSE mathematics are hindering their ability to reach the highest grades
Her Majesty’s Chief Inspector, Sir Michael Wilshaw said:
I want all children to have the best education they can and mathematics is a fundamental part of that. It is essential for everyday life and understanding of our world. Too many pupils do not fulfil their potential, including many of the most able, and those who get off to a poor mathematical start or fall behind in their learning never catch up.
We know it can be done. Over half of the schools visited in the survey were judged to be good or outstanding in mathematics, although even in these schools some inconsistencies in the quality of teaching need to be tackled.
We must all play our part to ensure that all pupils receive the best possible mathematics education. Ofsted will support schools to learn from the best, those with the best teaching and assessment and a well organised, mathematically rich, engaging curriculum.
Ofsted will produce support materials to help schools identify and remedy weaknesses in mathematics. It will raise ambition for the mathematics education of all pupils by placing greater emphasis in school inspection on:
-
how effectively schools tackle inconsistency in the quality of mathematics teaching
-
how well teaching fosters understanding
-
pupils’ skills in solving problems
-
challenging extensive use of early and repeated entry to GCSE examinations
The report recommends that the Department for Education should raise national mathematical ambition and take action to improve pupils’ mathematical knowledge and understanding. They should raise ambition for more-able pupils, in particular expecting those pupils who attained Level 5 at Key Stage 2 to gain A* or A grades at GCSE.
They should ensure end-of-key-stage assessments and GCSE and AS/A-level examinations require pupils to solve both familiar and unfamiliar problems and demonstrate fluency and accuracy in recalling and using essential knowledge and mathematical methods.
Welcoming the report, which contains good practice examples of mathematics teaching, National Numeracy’s chief executive, Mike Ellicock, said:
We believe every child can become a numerate adult – with skilful teaching in school and encouragement at home. This impressive report draws attention to the vital importance of numeracy and we hope its findings will be acted upon. It is essential that we all recognise the need for better support for those who struggle to catch up - at school and post-school.
Professor Celia Hoyles, Director of the National Centre for Excellence in the Teaching of Mathematics (NCETM) said:
A deep understanding of mathematics and of subject-specific pedagogy is crucial for teachers of mathematics. The NCETM welcomes the recommendations Ofsted has made, and looks forward to helping to embed them as part of the professional development of all mathematics teachers.
Carol Vorderman MBE, Chair of the committee reporting last August to the Secretary of State for Education with the influential report A world class mathematics education for all our young people, said:
This report is most welcome as it highlights many of the issues, which our taskforce found consistently create an unequal playing field at all levels in school. Ofsted recognises that the teaching of mathematics and the training of teachers both need to improve. Primary initial teacher training has not addressed the lack of mathematical ability in graduates training to be teachers, almost all of whom gave up maths at GCSE level. My sadness is to see how marked the difference in achievement and education is for those students on free school meals. As a “free school meals kid” at a comprehensive myself it was only because of my superb maths teacher that I was able to get to Cambridge. It is time for change.
Neil Carberry, CBI Director of Employment and Skills, said:
Basic maths is essential for everyday life, as well as a key skill required in the workplace. That’s why it’s so troubling over a third of pupils did not gain grade C in GCSE maths in 2011. Employers want all staff to be numerate, which means being able to confidently handle numbers, work out percentages and make estimates. We strongly support the Ofsted recommendation to encourage more young people to continue maths education post-16.
Notes to editors
-
The report is based predominantly on evidence from inspections of mathematics between January 2008 and July 2011 in maintained schools in England. Inspectors visited 160 primary and 160 secondary schools and observed more than 470 primary and 1,200 secondary mathematics lessons. The report is also informed by good practice visits to 11 primary schools, 1 secondary school and 2 sixth form colleges, but the evidence from these visits is not included in the proportions quoted in the report. The report draws attention to serious inequalities in pupils’ experiences and achievements. It includes examples of good practice that help avoid or overcome the inequalities and weaker practice that exacerbates them. It builds on the inspection findings and case studies of ‘prime practice’ and ‘weaker factors’ of the 2008 report, Mathematics: understanding the score. It is also informed by the evidence underpinning the report - Good practice in primary mathematics, published in 2011.

 Whether I have remained so I know not, you must judge of that. Heaven knows I’ve tried. I have killed many men in my time, yet I have never slain wantonly or stained my hand in innocent blood, but only in self-defence. The Almighty gave us our lives, and I suppose He meant us to defend them, at least I have always acted on that, and I hope it will not be brought up against me when my clock strikes. There, there, it is a cruel and a wicked world, and for a timid man I have been mixed up in a great deal of fighting. I cannot tell the rights of it, but at any rate I have never stolen, though once I cheated a Kafir out of a herd of cattle. But then he had done me a dirty turn, and it has troubled me ever since into the bargain.
Well, it is eighteen months or so ago since first I met Sir Henry Curtis and Captain Good. It was in this way. I had been up elephant hunting beyond Bamangwato, and had met with bad luck. Everything went wrong that trip, and to top up with I got the fever badly. So soon as I was well enough I trekked down to the Diamond Fields, sold such ivory as I had, together with my wagon and oxen, discharged my hunters, and took the post-cart to the Cape. After spending a week in Cape Town, finding that they overcharged me at the hotel, and having seen everything there was to see, including the botanical gardens, which seem to me likely to confer a great benefit on the country, and the new Houses of Parliament, which I expect will do nothing of the sort, I determined to go back to Natal by the Dunkeld, then lying at the docks waiting for the Edinburgh Castle due in from England. I took my berth and went aboard, and that afternoon the Natal passengers from the Edinburgh Castle transhipped, and we weighed and put to sea.
Among these passengers who came on board were two who excited my curiosity. One, a gentleman of about thirty, was perhaps the biggest-chested and longest-armed man I ever saw.  I never saw a finer-looking man, and somehow he reminded me of an ancient Dane. Not that I know much of ancient Danes, though I knew a modern Dane who did me out of ten pounds; but I remember once seeing a picture of some of those gentry, who, I take it, were a kind of white Zulus.  As I looked at my friend standing there by the companion-ladder, I thought that if he only let his grow a little, put one of those chain shirts on to his great shoulders, and took hold of a battle-axe and a horn mug, he might have sat as a model for that picture. And by the way it is a curious thing, and just shows how the blood will out, I discovered afterwards that Sir Henry Curtis, for that was the big man’s name, is of Danish blood. He also reminded me strongly of somebody else, but at the time I could not remember who it was.

5/30 Seton Hall plan to reopen (Thanks J. Peters)
They key question as the coronavirus pandemic continues to unfold, albeit at a slowing pace: How is social distancing going to work at an institution with 10,000 students and 3,000 employees, especially in the classroom?
The answer is what Seton Hall calls “HyFlex blended approach” to instruction. A percentage of students essentially will videoconference into a classroom. Those who videoconference in might do so by choice or be part of a rotating schedule.
For example: A class that enrolls 20 students and meets twice per week might have 10 students in the classroom and 10 students videoconferencing in during Tuesday’s meeting, with the groups switching roles on Thursday.
“We’ve ordered the technology and we’re in the process of retrofitting all our classrooms,” Nyre said.
“We’ve mapped out 50% (reduction in capacity), 70% (reduction), and 6-foot social distancing mechanics to see how many students we can put in a classroom,” Nyre said. “No matter what density guidelines the state puts out, we’ll meet them.”
This approach also provides flexibility for students who’d rather not come to campus at all.

ReducedModel
This module contains implementation of angles to coordinates conversion for reduced protein models.
This layer converts the dihedral angles describing the backbone conformation of a protein to the coordinates of the backbone atoms.
During the forward pass, we save the products of transformation matrices for each atom: $$A_i = B_0 B_1 \cdots B_i$$ Notice that atom $3j$ is always N, atom $3j + 1$ is always CA, and atom $3j+2$ is always C. Thus transformation matrices $B_{3j+1}$ and $B_{3j+2}$ depend on the angles $\phi_j$ and $\psi_j$, correspondingly.
During the backward pass, we first compute the gradient of $\mathbf{x}_i$, the position of atom $i$, with respect to each "$\phi$" and "$\psi$" angle: $$ \frac{\partial \mathbf{x}_i}{\partial \phi_j} = B_0 B_1 \cdots \frac{\partial B_{3j+1}}{\partial \phi_j} \cdots B_i \mathbf{x}_0 $$ $$ \frac{\partial \mathbf{x}_i}{\partial \psi_j} = B_0 B_1 \cdots \frac{\partial B_{3j+2}}{\partial \psi_j} \cdots B_i \mathbf{x}_0 $$ We can rewrite these expressions using the matrices $A$ that we saved during the forward pass: $$ \frac{\partial \mathbf{x}_i}{\partial \phi_j} = A_{3j} \frac{\partial B_{3j+1}}{\partial \phi_j} A_{3j+1}^{-1} A_{i} \mathbf{x}_0 $$ $$ \frac{\partial \mathbf{x}_i}{\partial \psi_j} = A_{3j+1} \frac{\partial B_{3j+2}}{\partial \psi_j} A_{3j+2}^{-1} A_{i} \mathbf{x}_0 $$ Both the $A$ and $B$ matrices have the form: $$ T = \begin{bmatrix} R & \mathbf{x} \\ 0 & 1 \end{bmatrix} $$ and their inverses can be computed as follows: $$ T^{-1} = \begin{bmatrix} R^{T} & -R^{T}\mathbf{x} \\ 0 & 1 \end{bmatrix} $$ This allows us to compute all derivatives simultaneously on GPU. To compute the derivatives of the layer output $L$ with respect to the input angles, we just have to calculate the following sums: $$\sum_i \frac{\partial L}{\partial \mathbf{x}_i}\cdot \frac{\partial \mathbf{x}_i}{\partial \phi_j}$$ and $$\sum_i \frac{\partial L}{\partial \mathbf{x}_i}\cdot \frac{\partial \mathbf{x}_i}{\partial \psi_j}$$
from TorchProteinLibrary import ReducedModel
a2b = ReducedModel.Angles2Backbone()
angles = torch.randn(1, 3, 3, dtype=torch.float, device='cuda')
num_aa = torch.tensor([3], dtype=torch.int, device='cuda')
coords = a2b(angles, num_aa)
Implementation
The position of the $i$-th atom in the chain is obtained by: $$\mathbf{x}_i = B_0 B_1 \cdots B_i \mathbf{x}_0$$ where $\mathbf{x}_0$ is the position of the atom in the original reference frame and $B_i$ are transformation matrices parametrized by dihedral angles: $$B(\alpha, \beta, d) = \begin{bmatrix} \cos(\beta) & \sin(\alpha)\sin(\beta) & \cos(\alpha)\sin(\beta) & d\cos(\beta) \\ 0 & \cos(\alpha) & -\sin(\alpha) & 0 \\ -\sin(\beta) & \sin(\alpha)\cos(\beta) & \cos(\alpha)\cos(\beta) & -d\sin(\beta) \\ 0 & 0 & 0 & 1 \end{bmatrix}$$ The transformations are defined as follows:-
$C$-$N$ peptide bond of residue $j-1$:
Index: $i = 3j$
Transformation: $ B_i = B(\omega_{j-1}, \pi - 2.1186, 1.330)$ -
$N$-$C_{\alpha}$ bond of residue $j$:
Index: $i = 3j + 1$
Transformation: $ B_i = B(\phi_{j}, \pi - 1.9391, 1.460)$ -
$C_{\alpha}$-$C$ bond of residue $j$:
Index: $i = 3j + 2$
Transformation: $ B_i = B(\psi_{j}, \pi - 2.061, 1.525)$
During the forward pass, we save the products of transformation matrices for each atom: $$A_i = B_0 B_1 \cdots B_i$$ Notice that atom $3j$ is always N, atom $3j + 1$ is always CA, and atom $3j+2$ is always C. Thus transformation matrices $B_{3j+1}$ and $B_{3j+2}$ depend on the angles $\phi_j$ and $\psi_j$, correspondingly.
During the backward pass, we first compute the gradient of $\mathbf{x}_i$, the position of atom $i$, with respect to each "$\phi$" and "$\psi$" angle: $$ \frac{\partial \mathbf{x}_i}{\partial \phi_j} = B_0 B_1 \cdots \frac{\partial B_{3j+1}}{\partial \phi_j} \cdots B_i \mathbf{x}_0 $$ $$ \frac{\partial \mathbf{x}_i}{\partial \psi_j} = B_0 B_1 \cdots \frac{\partial B_{3j+2}}{\partial \psi_j} \cdots B_i \mathbf{x}_0 $$ We can rewrite these expressions using the matrices $A$ that we saved during the forward pass: $$ \frac{\partial \mathbf{x}_i}{\partial \phi_j} = A_{3j} \frac{\partial B_{3j+1}}{\partial \phi_j} A_{3j+1}^{-1} A_{i} \mathbf{x}_0 $$ $$ \frac{\partial \mathbf{x}_i}{\partial \psi_j} = A_{3j+1} \frac{\partial B_{3j+2}}{\partial \psi_j} A_{3j+2}^{-1} A_{i} \mathbf{x}_0 $$ Both the $A$ and $B$ matrices have the form: $$ T = \begin{bmatrix} R & \mathbf{x} \\ 0 & 1 \end{bmatrix} $$ and their inverses can be computed as follows: $$ T^{-1} = \begin{bmatrix} R^{T} & -R^{T}\mathbf{x} \\ 0 & 1 \end{bmatrix} $$ This allows us to compute all derivatives simultaneously on GPU. To compute the derivatives of the layer output $L$ with respect to the input angles, we just have to calculate the following sums: $$\sum_i \frac{\partial L}{\partial \mathbf{x}_i}\cdot \frac{\partial \mathbf{x}_i}{\partial \phi_j}$$ and $$\sum_i \frac{\partial L}{\partial \mathbf{x}_i}\cdot \frac{\partial \mathbf{x}_i}{\partial \psi_j}$$

Unlimited Games. How should Red play 61?

To lift, or not to lift, that is the question?
It is close but lifting with 21/15, 4/3 is the correct move. Being hit on the 4-pt is just too expensive for Red. 13/6 wins 5.5% more gammons but loses 4% more games and so the maths clearly dictates that lifting is correct.
13/6 is quite a big error but still the second-best play. Anything else is a blunder.

Rod Stewart to perform intimate gig to raise £1m for fight against cancer
The chance to attend the secret dinner party will be auctioned off, with funds going to the Teenage Cancer Trust.
by Craig SimpsonSir Rod Stewart is hoping to raise £1 million for the fight against cancer with an exclusive gig.
The legendary rocker will host and perform at a secret dinner party, planned by the singer and his wife Penny Lancaster.
Celebrity access will be part of a charity auction at the event.
Funds raised by the dinner will go to the Teenage Cancer Trust, and money will be bolstered by an auction of exclusive items.
One prize up for auction is a private dinner with Sir Rod and his wife at The Ritz.
Those attending the charity event will see the decor designed by the singer, with his favourite flowers, wine and food on display.
An Ed Sheeran signed guitar, and a chance to accompany Dame Emma Thompson to the premiere of Cruella will also be up for grabs in the auction, along with artwork created by Sir Rod's former bandmate Ronnie Wood.
All proceeds will go to the Teenage Cancer Trust.


A romance that started with a Facebook friend request in 2008 - and after nine years, 25 flights, and living together for 835+ days, Natalie finally decided to accept the request.
On 29th December 2016, we got engaged in beautiful Colombia and now we're beyond excited to tie the knot and celebrate our life together with all our nearest and dearest. We'd be absolutely over the moon to have you join us in the celebrations.
We hope to see you on our special day!
Excited is an understatement!

Gifts
As most of you know, we moved into our little flat together in 2015 and have since built our home with everything we need. Please don't feel obliged to give us a gift as it means more to us that you can join us on our special day, however, if you would like to, then a contribution towards our honeymoon would be greatly appreciated.
Where to stay?

Two arrests made as part of investigation into historic murder of Patrick Heeran
by By Digital Desk staffTwo people have been arrested in connection with a historic murder case.
Patrick Heeran was last seen in Mohill in Co Leitrim on October 3, 2011.
The 48-year-old disappeared without trace and the case was upgraded to murder fiver years later in 2016.
His body has never been found.
This afternoon a man in his mid-20s and a woman, also in her mid-20s, were both arrested in the midlands area and are detained at Tullamore garda station.
Gardaí siad that the man is detained under Section 4 of the Criminal Justice Act, 1984, while the woman is held under Section 30 of the Offences against the State Act, 1939.
The investigation is ongoing.

Incorrect syntax near 'WSSList' in dbSPSReporting.sql
Have you tried to use the SQL Server 2005 Report Pack for SPS? I had used the previous version of this for SQL 2000 last year, but hadn't used it for a while. I remember having issues with the install of that previous version, and sure enough I had more issues this time as well.
Here is the error message you will see when you run the dbSPSReporting.sql script:
Msg 102, Level 15, State 1, Procedure usp_Insert_FactWSS, Line 57 Incorrect syntax near 'WSSList'.
Cannot add rows to sys.sql_dependencies for the stored procedure because it depends on the missing
table 'usp_Insert_FactWSS'. The stored procedure will still be created; however, it cannot be
successfully executed until the table exists.
The problem is there is a missing comma after WSSDoc nvarchar(255):
Simply add the comma before you run the SQL script and everything will work fine. I find it very ironic that the new bug is right below the "Fix for Bug" comment that dealt with the previous problems in the first version. Bugs often introduce other bugs, but you would think something released for a Windows administrator would be checked a little closer.

Separated by birth,
A distance dictated by social norms.
But when two hearts align ,
Fate shall break all barriers.
I Held her hand, to escape civilization,
Only for her to be outcasted as a witch.
While I remain bewitched by her beauty,
She only held on to her prayers.
Tears rolled down their cheeks,
For the long lost soul.
Held their arms wide open,
To take her back into their arms.
Civilization accepted the bitter truth,
And a union was made.
"It's to last over an eternity" was the cry,
Only it echoed with no response in return.
A child born out of passion,
Filled the crack with happiness.
A sight so pure and serene,
Healed all the scars which were made.
Years passed,only blank faces to each other,
Simply,following the way of the world.
Dreams were shattered,
And the world around broken.
The eutony of the child's words,
The only source of pleasantry.
And soon innocence was to be lost,
As truth slowly beckoned to her.
A world broken into two,
She remain transfixed in between.
Hoping to unite the two,
But the two pieces were beyond repair.
Her mind poisoned by humankind,
The fire of her age ignited.
Drawing out her rebellious nature,
Casting out her voice.
Left demeaned by her age,
Her words were left unheeded.
She could only view the world,
With blurred vision hoping to seek solace.
Happiness,was a forgotten art,
She succumbed to the pain.
Left with nothing but despair,
She finally chose to give it all away.
The two pieces were united in loss,
Epiphany made its toll.
A lost art was revived,
Which could be seen through the gates of heaven.


Book Review
I find myself increasingly drawn to the field of Behavioral Economics (so much so that I was considering a second PhD to channelize my love!), and how beautifully evasive these concepts are in real life. Starting with Daniel Kahneman’s Thinking Fast and Slow, followed by the writings and blogs of Steven Levitt, Dan Ariely, Nate Silver and Barry Schwartz (and still others like Malcolm Gladwell), has set me thinking a lot about how insane and illogical we are. We do see ourselves as logical and reasonably intelligent people who do not fall for the usual traps (OK, maybe you didn’t see me that way, but we’ll let that slide for now…), but how fool-proof are we? What about the narrative fallacy - ‘aah, that makes sense now’ or ‘I thought so’ or confirmation biases?
‘The Black Swan’ by Nassim Nicholas Taleb (http://fooledbyrandomness.com/) has been on my list ever since I first got infatuated with this topic. I finally finished it last month. Man, is it it well-written! The guy is brilliant, and his wit and humor are unmatchable! Among other things, he leads (and concludes) with our love for everything normal, statistically speaking and otherwise, and how we can’t but help make the obvious blunders of predicting, quite erroneously, based on the past, even though we know fully well that life doesn’t present itself as a series of bell curves stringed together just so that we can get away with some easy math! You’ll hear a lot about epistemology (defined in PS3; truth be told, I hadn’t heard of this word until last month), mediocristan (the Gaussian life) vs extremistan (scale-free distributions encountered more often than not in real-life)
Here’s a snippet: https://drive.google.com/file/d/0B7_wAV4HsNrkQmdFMndHSHhldFE/view Never mind if you don’t get it. I enjoyed every last bit of the book, and hope that you do too! Give it a try - whether you love it or hate it, it would be time well-spent! :)
Happy reading!
PS1. I’ve heard that people either love it or hate it. Clearly, I fall in the bin #1. Do I agree with everything? Well, yeah, almost everything. PS2. Luckily, none of you are directly tied to economics or financial sectors. :D Well, scientists and statisticians have been insulted too, but the elegance of it makes it OK! Lots to think about.:) PS3. Epistemology studies the nature of knowledge, justification, and the rationality of belief. Much of the debate in epistemology centers on four areas: (1) the philosophical analysis of the nature of knowledge and how it relates to such concepts as truth, belief, and justification, (2) various problems of skepticism, (3) the sources and scope of knowledge and justified belief, and (4) the criteria for knowledge and justification.
Blurb
A black swan is a highly improbable event with three principal characteristics: It is unpredictable; it carries a massive impact; and, after the fact, we concoct an explanation that makes it appear less random, and more predictable, than it was.
The astonishing success of Google was a black swan; so was 9/11. For Nassim Nicholas Taleb, black swans underlie almost everything about our world, from the rise of religions to events in our own personal lives.
Why do we not acknowledge the phenomenon of black swans until after they occur? Part of the answer, according to Taleb, is that humans are hardwired to learn specifics when they should be focused on generalities.
We concentrate on things we already know and time and time again fail to take into consideration what we don’t know. We are, therefore, unable to truly estimate opportunities, too vulnerable to the impulse to simplify, narrate, and categorize, and not open enough to rewarding those who can imagine the “impossible.”
For years, Taleb has studied how we fool ourselves into thinking we know more than we actually do. We restrict our thinking to the irrelevant and inconsequential, while large events continue to surprise us and shape our world. Now, in this revelatory book, Taleb explains everything we know about what we don’t know. He offers surprisingly simple tricks for dealing with black swans and benefiting from them.
Elegant, startling, and universal in its applications ‘The Black Swan’ will change the way you look at the world. Taleb is a vastly entertaining writer, with wit, irreverence, and unusual stories to tell. He has a polymathic command of subjects ranging from cognitive science to business to probability theory.
‘The Black Swan’ is a landmark book – itself a black swan.

As we know Threads is a vulnerable lab application which looks the same like any other social media platform but the main motto is to solve the vulnerabilities present in it. So here is a guide on how to setup Threads application on your local system which is divided into two parts, one contain the information on how to install the prerequisite before setting up the lab and the other part contains how to setup lab if you already have the both prerequisite installed in your system.
How to setup Threads on your local system
Part-1:(Prerequisite for setting up lab)
There are only two prerequisite:
- Install Node.js for your system
Note: Check (npm -v and node -v) if the node is already installed then it’s not necessary to follow the node.js installation setup below. - Install MongoDB
Node.js Setup
- Go to your terminal
- $ sudo apt update
- $ cd ~
- $ curl -sL https://deb.nodesource.com/setup_14.x -o nodesource_setup.sh
- $ sudo bash nodesource_setup.sh
- $ sudo apt install nodejs
- Check the version after above commands with
- $ node -v
- $ npm -v
MongoDB setup
- Open up your terminal
- $ wget -qO - https://www.mongodb.org/static/pgp/server-4.4.asc | sudo apt-key add -
- $ sudo add-apt-repository 'deb [arch=amd64] https://repo.mongodb.org/apt/ubuntu focal/mongodb-org/4.4 multiverse'
- $ sudo apt-get update
- $ sudo apt install mongodb-org
- $ sudo systemctl enable --now mongod
- To check if the MongoDb was installed successfully use this command:
$ mongo --eval 'db.runCommand({ connectionStatus: 1 })' - You must get a output like this or similar to this after the above command which means MongoDB was installed properly
MongoDB shell version v4.4.0
connecting to: mongodb://<IP_ADDRESS>:27017/?compressors=disabled&gssapiServiceName=mongodb
Implicit session: session { "id" : UUID("2af3ab0e-2197-4152-8bd0-e33efffe1464") }
MongoDB server version: 4.4.0
{
"authInfo" : {
"authenticatedUsers" : [ ],
"authenticatedUserRoles" : [ ]
},
"ok" : 1
}
Part-2:(Setting up Threads app)
- First download the Threads application.
- Open up your terminal and go to the folder where the zip file got downloaded.
- Unzip the downloaded zip file for Threads application.
- Then use these commands to run the application server on your localhost:
- $ cd enciphers_web-master
- $ npm install
- $ npm start
- After using the above commands you will see the message in the terminal like these given below which means that the application server has been connected to the MongoDB database.
- As the Threads application is running on port no. 3000 in you localhost. So go to your browser and search http://localhost:3000/home to open the threads application.
><EMAIL_ADDRESS>start /root/Downloads/enciphers_web-master
> nodemon server.js
[nodemon] 2.0.4
[nodemon] to restart at any time, enter `rs`
[nodemon] watching path(s): *.*
[nodemon] watching extensions: js,mjs,json
[nodemon] starting `node server.js`
Connected to Database :: MongoDB
Connected to Moongose
The best way to learn something is to play with it.

--- creation_epoch:<PHONE_NUMBER> lastmod_epoch:<PHONE_NUMBER> categories: Security title: Protecting against MITM and sslstrip attacks --- I was playing with sslstrip and discovered that Google's Chrome and Mozilla's Firefox web browsers actually protect some popular web sites against it. sslstrip works by changing any requests of SSL (HTTPS) secure URLs into insecure ones. This would allow an attacker on the same network to trick users machines into using it for accessing sites (send network traffic to it) and rewriting the site code.
This isn't a problem if the user types in the URL with https:// first, but most users don't so usually a site like your bank or gmail or whatever will redirect you to the secure site. sslstrip takes advantage of this and stops the secure redirect which most servers.
The solution to stopping this is called HSTS. Basically the server responds telling the web browser to never use insecure URLs no matter what the server's response HTML says. Neat idea.
One thing of course is that sslstrip or another program could just remove the HSTS from the server response. Google prevents this currently by simply hard-coding in web sites that should reply with the HSTS headers (ex: paypal, gmail). This isn't scalable so one proposal is to have the HSTS required moved into DNS with DNSSEC instead.
