MetadataShow full item record
Two overlapping confidence intervals have been used in many sources in the past 30 years to conduct statistical inferences about two normal population means. Several authors have examined the shortcomings of Overlap procedure in the past 13 years and have determined that such a method completely distorts the significance level of testing the null hypothesis of two normal population means and reduces the statistical power of the test. Nearly all results for small sample sizes in Overlap literature have been obtained either by simulation or by somewhat inaccurate formulas, and only large-sample (or known-variance) exact information has been provided. Nevertheless, there are many aspects of Overlap that have not yet been presented in the literature and compared against the standard statistical procedure. This paper will present exact formulas for the % overlap, ranging in the interval (0, 61.3626%] for a 0.05-level test, that two independent confidence intervals (CIs) can have, but the null hypothesis of equality of two population means must still be rejected at a pre-assigned level of significance for sample sizes? 2. The exact impact of Overlap on the?alpha-level and the power of pooled-t test will also be presented. Further, the impact of Overlap on the power of the F-statistic in testing the null hypothesis of equality of two normal process variances will be assessed. Finally, we will use the noncentral t distribution, which has never been applied in Overlap literature, to assess the Overlap impact on type II error probability when testing the equality of two population means for sample sizes equal two.

- 2 hr 37 min
Pelle the Conqueror is a 1987 Danish-Swedish film directed by Bille August, based on an internationally acclaimed novel by Martin Andersen NexÃ¸. Set on the island of Bornholm, Denmark, in the early 20th century, the movie tells the story of a poor Swedish widower, Lasse (Max von Sydow), and his young son, Pelle (Pelle Hvenegaard), who move to Denmark in search of a better life. The film follows their struggles as they face poverty, discrimination, and social injustice, while striving to make a living and find a sense of belonging in a new country.
At the beginning of the film, Lasse and Pelle are seen in Sweden, living in a cramped and dark basement where they work as laborers in a farm. Lasse is old and weak, while Pelle is a curious and imaginative child who dreams of exploring the world around him. After Lasse loses his job, he decides to take a chance and go to Denmark, where he believes life is better. They arrive in a small Danish fishing village, where they are greeted with suspicion and hostility by the locals, who see them as unwanted outsiders.
Despite the challenges they face, Lasse and Pelle manage to find work at a farm owned by the wealthy farmer Kongstrup (Erik Paaske). However, they soon realize that their new employer is a brutal and exploitative man who treats his workers like slaves. They are forced to work long hours without rest and endure verbal and physical abuse. Pelle, who is sent to attend a school for poor children, also faces discrimination and bullying from his classmates, who ridicule him for his Swedish accent and poor clothes.
As the story progresses, Lasse becomes increasingly resentful of Kongstrup's abuse and decides to rebel against him in order to protect his rights and dignity. Meanwhile, Pelle becomes friends with a kind and intelligent girl, Anna, who helps him cope with his struggles and encourages him to pursue his dreams. Together, they explore the natural beauty of the island and learn about the world through books and stories.
The film's climax is a powerful and emotionally charged scene, where Lasse and Pelle confront Kongstrup and his gang, and demand their rights and freedom. The scene is a symbol of the struggle for justice and equality, and the power of hope and solidarity in the face of oppression.
Overall, Pelle the Conqueror is a captivating and poignant film that portrays the harsh realities of poverty and social inequality, as well as the resilience and courage of the human spirit. The performances of Max von Sydow and Pelle Hvenegaard are outstanding, conveying the depth and complexity of their characters with subtlety and sensitivity. The cinematography and music also add to the film's emotional impact, creating a vivid and immersive atmosphere that transports the viewers into the world of the story. Pelle the Conqueror won several awards, including the Palme d'Or at the Cannes Film Festival, and remains a timeless classic of Danish and Swedish cinema.
Pelle the Conqueror is a 1988 drama with a runtime of 2 hours and 37 minutes. It has received mostly positive reviews from critics and viewers, who have given it an IMDb score of 7.8.

TFSD Cancels School Friday Due To Air Quality
The Twin Falls School District has cancelled school for Friday August 21, 2020 due to poor air quality levels. Fire season has been especially bad for the air in Southern Idaho as a number of fires are spreading smoke across the area. Multiple fires started over the night Wednesday and another fire near the Utah border ignited Thursday. The smoke has caused the air quality index to skyrocket, reaching over 188 by the end of school Thursday. The school email to parents states 'Twin Falls School District policy on air quality for student activities (including physical education classes, recess, and athletics practices) restricts outdoor activities anytime the air quality index is over 150.'
Along with complicated situations in schools due to the required masks for COVID Protocol, holding classes at school isn't possible or safe right now. The current protocol level allows students to attend school while wearing masks. Each hour the students are allowed, in most cases, to step outside and take off their masks for a few minutes while social distancing. Sending students out in the poor air would force them to breath in the smoke.
Officials believe the poor air quality will continue through Friday, therefore the decision was made to cancel in school classes and activities.
The haze from the fires also made for an interesting sight when the sun rose on Thursday morning, looking like a dark red ball in the sky rather than the regular glowing yellow sun.


Quantum well in nanotechnology
Definition of quantum well: If one dimension of the material is reduced to nano range while the other two dimensions remain large, then the material or structure is called quantum well. Quantum well is also called nanolayers.
Preparation of quantum well:
The quantum well in nanotechnology is formed by sandwiching a material (fore example GaAs) between the two layers of another material having broader gap (For example aluminium arsenide). The layers are prepared by the chemical vapor deposition or epitaxy.
In nanotechnology, a quantum well is like a potential well in which the carrier particles are trapped and it took place when the thickness of the well is comparable to the de Broglie wavelength of the carriers.
Application of quantum well:
 1. Quantum wells are used in diode lasers.
 2. Quantum well are used as infra red detectors.
I hope you have understood the meaning of quantum well in nanotechnology.

[[Reverse_Mapping_Btree]]
== Reverse-Mapping B+tree
[NOTE]
This data structure is under construction! Details may change.
If the feature is enabled, each allocation group has its own reverse
block-mapping B+tree, which grows in the free space like the free space
B+trees. As mentioned in the chapter about
xref:Reconstruction[reconstruction], this data structure is another piece of
the puzzle necessary to reconstruct the data or attribute fork of a file from
reverse-mapping records; we can also use it to double-check allocations to
ensure that we are not accidentally cross-linking blocks, which can cause
severe damage to the filesystem.
This B+tree is only present if the +XFS_SB_FEAT_RO_COMPAT_RMAPBT+
feature is enabled. The feature requires a version 5 filesystem.
Each record in the reverse-mapping B+tree has the following structure:
[source, c]
----
struct xfs_rmap_rec {
__be32 rm_startblock;
__be32 rm_blockcount;
__be64 rm_owner;
__be64 rm_fork:1;
__be64 rm_bmbt:1;
__be64 rm_unwritten:1;
__be64 rm_unused:7;
__be64 rm_offset:54;
};
----
*rm_startblock*::
AG block number of this record.
*rm_blockcount*::
The length of this extent.
*rm_owner*::
A 64-bit number describing the owner of this extent. This is typically the
absolute inode number, but can also correspond to one of the following:
.Special owner values
[options="header"]
|=====
| Value | Description
| +XFS_RMAP_OWN_NULL+ | No owner. This should never appear on disk.
| +XFS_RMAP_OWN_UNKNOWN+ | Unknown owner; for EFI recovery. This should never appear on disk.
| +XFS_RMAP_OWN_FS+ | Allocation group headers
| +XFS_RMAP_OWN_LOG+ | XFS log blocks
| +XFS_RMAP_OWN_AG+ | Per-allocation group B+tree blocks. This means free space B+tree blocks, blocks on the freelist, and reverse-mapping B+tree blocks.
| +XFS_RMAP_OWN_INOBT+ | Per-allocation group inode B+tree blocks. This includes free inode B+tree blocks.
| +XFS_RMAP_OWN_INODES+ | Inode chunks
| +XFS_RMAP_OWN_REFC+ | Per-allocation group refcount B+tree blocks. This will be used for reflink support.
| +XFS_RMAP_OWN_COW+ | Blocks that have been reserved for a copy-on-write operation that has not completed.
|=====
*rm_fork*::
If +rm_owner+ describes an inode, this can be 1 if this record is for an
attribute fork.
*rm_bmbt*::
If +rm_owner+ describes an inode, this can be 1 to signify that this record is
for a block map B+tree block. In this case, +rm_offset+ has no meaning.
*rm_unwritten*::
A flag indicating that the extent is unwritten. This corresponds to the flag in
the xref:Data_Extents[extent record] format which means +XFS_EXT_UNWRITTEN+.
*rm_offset*::
The 54-bit logical file block offset, if +rm_owner+ describes an inode.
Meaningless otherwise.
[NOTE]
The single-bit flag values +rm_unwritten+, +rm_fork+, and +rm_bmbt+ are packed
into the larger fields in the C structure definition.
The key has the following structure:
[source, c]
----
struct xfs_rmap_key {
__be32 rm_startblock;
__be64 rm_owner;
__be64 rm_fork:1;
__be64 rm_bmbt:1;
__be64 rm_reserved:1;
__be64 rm_unused:7;
__be64 rm_offset:54;
};
----
For the reverse-mapping B+tree on a filesystem that supports sharing of file
data blocks, the key definition is larger than the usual AG block number. On a
classic XFS filesystem, each block has only one owner, which means that
+rm_startblock+ is sufficient to uniquely identify each record. However,
shared block support (reflink) on XFS breaks that assumption; now filesystem
blocks can be linked to any logical block offset of any file inode. Therefore,
the key must include the owner and offset information to preserve the 1 to 1
relation between key and record.
* As the reference counting is AG relative, all the block numbers are only
32-bits.
* The +bb_magic+ value is "RMB3" (0x524d4233).
* The +xfs_btree_sblock_t+ header is used for intermediate B+tree node as well
as the leaves.
* Each pointer is associated with two keys. The first of these is the "low
key", which is the key of the smallest record accessible through the pointer.
This low key has the same meaning as the key in all other btrees. The second
key is the high key, which is the maximum of the largest key that can be used
to access a given record underneath the pointer. Recall that each record
in the reverse mapping b+tree describes an interval of physical blocks mapped
to an interval of logical file block offsets; therefore, it makes sense that
a range of keys can be used to find to a record.

GUSINJE – RYCO Local Branch Office in Montenegro in partnership with the Association of Women Entrepreneurs and with the support of the Embassy of the French Republic in Montenegro organized a two-day camp in Gusinje "A Better Region Starts with YOUth" on 11 – 12 June where they discussed youth activism, entrepreneurship and regional cooperation, but also shared their impressions from RYCO youth exchanges.
The camp's opening ceremony kicked off with the introductory speeches delivered by Ambassador of the French Republic H. E. Ms Christine Toudic and RYCO Local Branch Officer in Montenegro Mr Edin Koljenović. They both highlighted the importance of the implementation of youth exchange programs, as well as networking between young people in the Western Balkans but also within their own societies.
The two-day camp gathered high school students from several Montenegrin municipalities such as Nikšić, Bijelo Polje, Berane, Plav and Gusinje. Students of the Secondary Economic and Catering School from Nikšić and the Secondary Vocational School from Berane who were participating in the first youth exchange programs supported by RYCO attended the event, too.
The participants had the opportunity to attend a number of workshops dealing with topics such as youth civic activism, youth entrepreneurship and networking opportunities in the regional context. Furthermore, they also had the opportunity to learn more about activities and opportunities for young people that the French Institute and French Cultural Centre in Montenegro offer.
Finally, a special session was conducted by the participants of the first RYCO youth exchanges where they motivatingly shared their impressions from the exchanges with their peers. Their speeches reflected sincere emotions provoked by beautiful memories, encouraging the rest of the youth audience to take part in such or similar projects conducted by RYCO and its partners in the future.

An Arduino-based rocket motor thrust test stand
If you enjoy model rocketry, you may wonder just what the thrust curve of the motors you're using looks like. In order to answer that question, YouTuber ElementalMaker decided to construct his own test stand using an Arduino Uno coupled to a 10Kg load cell with an HX711 amplifier board. The test procedure is started with a little red button, and after warning LED blinks away for 10 seconds, it activates a relay and fires the motor under into the stand.
The experimental setup seen in the video yields successful thrust curves for both a ½ inch and ¾ inch motor. As you might expect, the ¾ produces more thrust than its smaller cousin, though at 2,683 grams versus the ½ inch motor's 658, it's an impressive difference indeed.
The heart of the stand is a common load cell (the sort of thing you'd find in a digital scale) coupled with a HX711 amplifier board mounted between two plates, with a small section of vertical PVC pipe attached to the topmost plate to serve as a motor mount. This configuration is capable of measuring up to 10 kilograms with an 80Hz sample rate, which is critically important at this type of rocket motors only burn for a few seconds to begin with. The sensor produces hundreds of data points during the short duration of the build, which is perfect for graphing the motor's thrust curve over time.
Given such a small window in which to make measurements, [ElementalMaker] didn't want to leave anything to chance. So rather than manually igniting the motor and triggering the data collection, the stand's onboard Arduino does both automatically. Pressing the red button on the stand starts a countdown procedure complete with flashing LED, after which a relay is used to energize a nichrome wire "electronic match" stuck inside the motor.
The project is based on a paper archived here if you'd like to examine the design.

Faceless body in performance
MetadataShow full metadata
Faceless Body in Performance is a practice-led research project in live and digital performance. There are two series of solo performances, Breath of Air and Black Glove, which explore choreographic procedures that can direct the audience towards ambiguous plays of relation within the embodied, sensory encounter of the performance. The focus is on decentring the modalities of visibility, invisibility, aurality, stillness, and motion, with the aim of exposing intermodal relationships across the senses and genders. The project is located in a post-phenomenological paradigm where the body, environment, and technology are regarded as a field of mutually dependent relations. Don Ihde's post-phenomenological exploration of amplification technology and notion of an auditory turn, provide a framework for viewing the solo performances as indeterminate plays of relation across the senses and technology. Jacques Derrida's strategies of deconstruction and notion of undecidability, provide a lens for viewing each of the solo performances as an open-ended process that is irreducible to a final meaning. The project argues that there is a range of choreographic procedures, which can expose performance as an embodied, relational process that resists stabilisation into a single modality or meaning.


FtlDat - itb-community/ITB-ModLoader Wiki
Table of Contents

FtlDat
A class used for dealing with .dat archive files, providing several useful abstractions and functionalities.
Keep in mind that this is an internal mod loader API that is generally not intended for usage by regular mods.
For functions that mods should use for dealing with assets, see modApi | Assets
Memory usage
When loaded from an existing .dat archive, all of its contents are loaded into memory. At the time of writing, the vanilla resource.dat file takes around 347MB on disk, so that's also the approximate amount of RAM that an FtlDat instance loaded from it is going to take.
As such, it is important to:
 - Create new instances of FtlDat as infrequently as possible,
 - Immediately destroy them once they're no longer needed, using destroy.
Usage notes
General usage pattern is as follows:
local ftldat = FtlDat("resources/resource.dat")
-- modify the archive using ftldat:put_x
ftldat:put_entry_string("some/file.txt", "Stuff")
-- write out the modified archive
ftldat:write("resources/resource.dat")
-- cleanup
ftldat:destroy()
For regular usage, the put_entry_file function should be sufficient, since it is rare that mods need to dynamically create a file's content. For these more advanced cases, put_entry_string and put_entry_byte_array are more suitable.
For some reason, Lua has some trouble with large strings that describe contents of binary files, such as images, and tends to crash. As such, for dealing with images in cases where put_entry_file is insufficient, the put_entry_byte_array is preferable. FtlDat by itself doesn't provide any abstraction over byte arrays.

(constructor)
Signature: FtlDat FtlDat(path)
Argument name Type Description
path string Path to a .dat file. Optional.
Creates an instance of FtlDat class, which is an in-memory representation of a .dat file.
If path argument is provided, the instance will contain data from the specified archive. If path points to a file that does not exist, an error will be thrown. If path is nil, the instance will represent a new, empty archive that contains no data.
Example:
local ftldat = FtlDat("resources/resource.dat")

remove_all_files
Signature: void remove_all_files()
Removes all files from this FtlDat archive.
Example:
local ftldat = FtlDat("resources/resource.dat")
ftldat:remove_all_files()

write
Signature: void write(outputPath)
Argument name Type Description
outputPath string Path to the file in which the contents of the .dat archive will be written
Writes out the data currently stored in this FtlDat instance to the specified file. Creates a new file if it doesn't exist yet, and overwrites the file if it already exists.
Example:
local ftldat = FtlDat("resources/resource.dat")

put_entry_string
Signature: void put_entry_string(innerPath, content)
Argument name Type Description
innerPath string Path to the file within the .dat archive
content string Content of the file, in the form of a string
Sets the content of the file at the specified innerPath to the specified content. Creates a new entry in the FtlDat instance if it doesn't already exist, and overwrites it if it does.
This method is not suited to adding large file entries, such as images. Instead, use put_entry_byte_array or put_entry_file.
Example:
local ftldat = FtlDat("resources/resource.dat")
ftldat:put_entry_string("path/to/some_file.txt", "This will be stored inside the file")

put_entry_byte_array
Signature: void put_entry_byte_array(innerPath, byteArray)
Argument name Type Description
innerPath string Path to the file within the .dat archive
byteArray table Content of the file, in the form of a byte array
Sets the content of the file at the specified innerPath to the specified content. Creates a new entry in the FtlDat instance if it doesn't already exist, and overwrites it if it does.
Example:
local ftldat = FtlDat("resources/resource.dat")
ftldat:put_entry_byte_array("path/to/some_binary_file.bin", { 35, 87, 123 })

put_entry_file
Signature: void put_entry_file(innerPath, sourcePath)
Argument name Type Description
innerPath string Path to the file within the .dat archive
sourcePath string Path to the file on the file system, whose content will be used as the entry's content
Sets the content of the file at the specified innerPath to the specified sourcePath file's content. Creates a new entry in the FtlDat instance if it doesn't already exist, and overwrites it if it does.
This immediately reads the specified source file, and stores its content in the entry within the FtlDat instance.
Example:
local ftldat = FtlDat("resources/resource.dat")
ftldat:put_entry_file("img/units/my_unit_image.png", "path/to/my_mod/my_unit_image.png")

file_exists
Signature: boolean file_exists(innerPath)
Argument name Type Description
innerPath string Path to the file within the .dat archive
Returns true if an entry with the specified innerPath exists within this FtlDat instance, false otherwise.
Example:
local ftldat = FtlDat("resources/resource.dat")
LOG(ftldat:file_exists("some/file.txt")) -- prints false
ftldat:put_entry_string("some/file.txt", "Stuff")
LOG(ftldat:file_exists("some/file.txt")) -- prints true

entry_content_string
Signature: string entry_content_string(innerPath)
Argument name Type Description
innerPath string Path to the file within the .dat archive
Returns the content of the entry at the specified innerPath within this FtlDat instance, as a string. This may or may not work if the entry's content was originally added as a byte array.
Example:
local ftldat = FtlDat("resources/resource.dat")
ftldat:put_entry_string("some/file.txt", "Stuff")
local content = ftldat:entry_content_string("some/file.txt")
LOG(content) -- prints "Stuff"

entry_content_byte_array
Signature: table entry_content_string(innerPath)
Argument name Type Description
innerPath string Path to the file within the .dat archive
Returns the content of the entry at the specified innerPath within this FtlDat instance, as a byte array. This may or may not work if the entry's content was originally added as a string.
Example:
local ftldat = FtlDat("resources/resource.dat")
ftldat:put_entry_string("some/file.bin", { 35, 87, 123 })
local content = ftldat:entry_content_string("some/file.txt")
LOG(content) -- prints "Stuff"

inner_paths
Signature: table inner_paths()
Returns a table list of all inner paths within this FtlDat instance.
Example:
local ftldat = FtlDat("resources/resource.dat")
for index, innerPath in ipairs(ftldat:inner_paths()) do
 LOG(index, innerPath)
end

extract_file
Signature: void extract_file(innerPath, destinationPath)
Argument name Type Description
innerPath string Path to the file within the .dat archive
destinationPath string Path on the file system, to which the entry will be extracted
Extracts the entry at the specified innerPath from this FtlDat instance, and saves it to the specified destinationPath.
Example:
local ftldat = FtlDat("resources/resource.dat")
ftldat:extract_file("img/units/player/mech_punch.png", "resources/unpacked/mech_punch.png")

destroy
Signature: void destroy()
Sets the internal userdata reference to nil and invokes collectgarbage(), so that Lua immediately frees up all memory taken up by this FtlDat instance. Once this function is called, this FtlDat instance is no longer usable.

Lexicon
byte array
A byte array is a table of u8 (0-255, inclusive) integer numbers, eg. { 35, 87, 123 }.

PP Full Form, What is the Full form of PP ?
The Full form of PP is Pancreatic Polypeptide. The pancreas is a gland, having both a digestive exocrine and an endocrine function. As an endocrine gland, it functions mostly to regulate blood sugar levels, secreting the hormones insulin, glucagon, somatostatin, and pancreatic polypeptide. PP is a thirty six amino acid peptide produced and secreted by PP cells (originally termed F cells) of the pancreas which are primarily located in the Islets of Langerhans. It is part of a family of peptides that also includes Peptide YY (PYY) and Neuropeptide Y (NPY). PP is rapidly released after a meal but remains elevated for four to six hours in humans with the Vagus nerve being the major stimulator. PP has effects on GI motility, metabolism and food intake. A potential role as a satiety factor comes from the observation that PP secretion is absent in obese children with Prader-Willi syndrome. Its primary action on the exocrine pancreas is to inhibit secretion in vivo by acting on receptors in the brain leading to inhibition of vagal output to the pancreas. The function of PP is to self-regulate pancreatic secretion activities (endocrine and exocrine). It also has effects on hepatic glycogen levels and gastrointestinal secretions.

Exceptions with Elasticsearch via Kibana
Harness Analysis of Elasticsearch Verification
Integration Process Summary
You set up ELK and Harness in the following way:
 1. ELK - Monitor your application using ELK. In this article, we assume that you are using ELK to monitor your application already.
 2. Verification Provider Setup - In Harness, you connect Harness to your ELK account, adding ELK as a Harness Verification Provider.
 3. Harness Application - Create a Harness Application with a Service and an Environment. We do not cover Application setup in this sequence. See Application Components.
 4. 24/7 Service Guard SetupIn the Environment, set up 24/7 Service Guard to monitor your live, production application.
 5. Verify Deployments:
 1. Add a Workflow to your Harness Application and deploy your microservice or application to the service infrastructure/Infrastructure Definition in your Environment.
 2. After you have run a successful deployment, you then add verification steps to the Workflow using your Verification Provider.
 3. Harness uses unsupervised machine-learning and Elasticsearch analytics to analyze your future deployments, discovering events that might be causing your deployments to fail. Then you can use this information to set rollback criteria and improve your deployments.

PostgreSQL Tutorial: Delete Duplicate Rows
September 15, 2023
Summary: in this tutorial, you will learn how to use various techniques to delete duplicate rows in PostgreSQL.
Preparing sample data
First, create a new table named basket that stores fruits:
CREATE TABLE basket(
 id SERIAL PRIMARY KEY,
 fruit VARCHAR(50) NOT NULL
);
Second, insert some fruits into the basket table.
INSERT INTO basket(fruit) values('apple');
INSERT INTO basket(fruit) values('apple');
INSERT INTO basket(fruit) values('orange');
INSERT INTO basket(fruit) values('orange');
INSERT INTO basket(fruit) values('orange');
INSERT INTO basket(fruit) values('banana');
Third, query data from the basket table:
SELECT
 id,
 fruit
FROM
 basket;
fruit table
As you can see, we have some duplicate rows such as 2 apples and 3 oranges in the basket table.
Finding duplicate rows
If the table has few rows, you can see which ones are duplicate immediately. However, it is not the case with the big table.
The find the duplicate rows, you use the following statement:
SELECT
 fruit,
 COUNT( fruit )
FROM
 basket
GROUP BY
 fruit
HAVING
 COUNT( fruit )> 1
ORDER BY
 fruit;
img
Deleting duplicate rows using DELETE USING statement
The following statement uses the DELETE USING statement to remove duplicate rows:
DELETE FROM
 basket a
 USING basket b
WHERE
 a.id < b.id
 AND a.fruit = b.fruit;
In this example, we joined the basket table to itself and checked if two different rows (a.id < b.id) have the same value in the fruit column.
Let's query the basket table again to verify whether the duplicate rows were deleted:
SELECT
 id,
 fruit
FROM
 basket;
delete duplicate rows in postgresql example - keep highest id
As you can see, the statement removed the duplicate rows with lowest ids and keep the one with the highest id.
If you want to keep the duplicate rows with the lowest id, you use just need to flip the operator in the WHERE clause:
DELETE FROM
 basket a
 USING basket b
WHERE
 a.id > b.id
 AND a.fruit = b.fruit;
To check whether the statement works correctly, let's verify the data in the basket table:
SELECT
 id,
 fruit
FROM
 basket;
Result:
delete duplicate rows in postgresql example - keep lowest id
Perfect! the duplicate rows with the lowest ids are retained.
Deleting duplicate rows using subquery
The following statement uses a suquery to delete duplicate rows and keep the row with the lowest id.
DELETE FROM basket
WHERE id IN
 (SELECT id
 FROM
 (SELECT id,
 ROW_NUMBER() OVER( PARTITION BY fruit
 ORDER BY id ) AS row_num
 FROM basket ) t
 WHERE t.row_num > 1 );
In this example, the subquery returned the duplicate rows except for the first row in the duplicate group. And the outer DELETE statement deleted the duplicate rows returned by the subquery.
If you want to keep the duplicate row with highest id, just change the order in the subquery:
DELETE FROM basket
WHERE id IN
 (SELECT id
 FROM
 (SELECT id,
 ROW_NUMBER() OVER( PARTITION BY fruit
 ORDER BY id DESC ) AS row_num
 FROM basket ) t
 WHERE t.row_num > 1 );
In case you want to delete duplicate based on values of multiple columns, here is the query template:
DELETE FROM table_name
WHERE id IN
 (SELECT id
 FROM
 (SELECT id,
 ROW_NUMBER() OVER( PARTITION BY column_1,
 column_2
 ORDER BY id ) AS row_num
 FROM table_name ) t
 WHERE t.row_num > 1 );
In this case, the statement will delete all rows with duplicate values in the column_1 and column_2 columns.
Deleting duplicate rows using an immediate table
To delete rows using an immediate table, you use the following steps:
 1. Create a new table with the same structure as the one whose duplicate rows should be removed.
 2. Insert distinct rows from the source table to the immediate table.
 3. Drop the source table.
 4. Rename the immediate table to the name of the source table.
The following illustrates the steps of removing duplicate rows from the basket table:
-- step 1
CREATE TABLE basket_temp (LIKE basket);
-- step 2
INSERT INTO basket_temp(fruit, id)
SELECT
 DISTINCT ON (fruit) fruit,
 id
FROM basket;
-- step 3
DROP TABLE basket;
-- step 4
ALTER TABLE basket_temp
RENAME TO basket;
In this tutorial, you have learned how to delete duplicate rows in PostgreSQL using the DELETE USING statement, subquery, and the immediate table techniques.

Holy Cross Energy announced the completion of its new solar array and battery storage project at Colorado Mountain College's Spring Valley campus in Glenwood Springs. This project is a collaboration between Holy Cross Energy, Colorado Mountain College, Ameresco, Sunsense and Friends. The utility-scale solar and storage project is a step towards Holy Cross Energy's goal of producing 100% carbon-free electricity by 2030, as well as Colorado Mountain College's intention to be entirely carbon neutral by 2050.
The system includes 13,500 solar panels located at the campus, which provide 4.5 MW of solar power, and 68 battery stacks that provide 5MW/15MWh of battery energy storage. Most of the solar panels are installed using single-axis tracking, which uses one axis of rotation and takes advantage of the different terrain and space constraints of the site. The 68 battery stacks are stored in four on-site containers, each of which also contains an HVAC system to control temperature and humidity. Fire suppression measures are in place for further safety. The batteries will be used to store energy, discharging it during peak demand hours to reduce overall energy costs and save money for Holy Cross Energy members.
Sam Whelan, Holy Cross Energy's Vice President of Power Supply states "The HCE/CMC solar plus storage project is a great example of a win-win renewable project. Not only does the project assist both HCE and CMC toward their renewable and carbon goals, but the battery also provides us with the flexibility to operate an increasingly renewable portfolio. To top it all off, we're able to do this in a financially responsible way that saves money for all our members."The annual offset of greenhouse gas emissions from this project is 6,853 metric tons of carbon dioxide equivalent, or the same as removing 1,481 passenger vehicles from the road or saving 7,551,051 pounds of coal every year. Three CMC campuses, including Vail Valley, Aspen, and Spring Valley, will receive power from this new installation.


Rotating a 2D Array by 90 Degrees (Java)
The problem is: Implement a function that takes a square 2D array (# columns = # rows = n) and rotates it by 90 degrees. Do not create a separate 2D array for the rotation, it rotates in the 2D array.
Example:
int a1[][] = {{1, 2, 3},
 {4, 5, 6},
 {7, 8, 9}};
 // rotate(a1, 3) should return:
 // [[7, 4, 1],
 // [8, 5, 2],
 // [9, 6, 3]]
Example:
 int a2[][] = {{1, 2, 3, 4},
 {5, 6, 7, 8},
 {9, 10, 11, 12},
 {13, 14, 15, 16}};
 // rotate(a2, 4) should return:
 // [[13, 9, 5, 1],
 // [14, 10, 6, 2],
 // [15, 11, 7, 3],
 // [16, 12, 8, 4]]
My method rotates the matrix in the same array and does not need an additional matrix to store temp data. It is different from many other solutions online.
a. The Swap:
Each element in the rotation is changing position with 3 other elements in the 2D array: a->b, b->c, c->d, d->a
 [?, a, ?, ?]
 [?, ?, ?, b]
 [d, ?, ?, ?]
 [?, ?, c, ?]
Observation 1: If a={i,j}, then b={j,n-1-i}, c={n-1-i, n-1-j},d={n-1-j,i}
b. Row i:
Each rotation happens in a "ring" (example, a1, a2, a2, b1, b2, b3….d2, d2), only the first n-1 elements in the first row needs to be swapped. For example, in this 4 x 4 matrix, I only need to swap a1, a2, a3, with b1, b2, b3. Then swap b1, b2, b3 with c1, c2, c3. and this continues.
 [a1, a2, a3, b1]
 [d3, ??, ??, b2]
 [d2, ??, ??, b3]
 [d1, c3, c2, c1]
Observation 2: At each row i, only swap the first n-1 elements. i changes from 0 to n-2, So the outer loop should be for (int i=0; i < n-1; i++):
c. Column j:
Swapping from the outside ring (1's) to the inner rings (2's), the number of iteration decrements by 2. For example, in this 4 x 4 Matrix, the outside ring (1's) has a length of 4, the inner ring (2's) has a length of 2.
 [1, 1, 1, 1]
 [1, 2, 2, 1]
 [1, 2, 2, 1]
 [1, 1, 1, 1]
Observation 3: At ith ring, the column number j starts at ith element and ends at n-1-i th elements. j changes from i to n-2-i So the inner loop is for (int j=i; j<n-1-i; j++)
Put everything together:
 public static int[][] rotate(int[][] a, int n) {
 for (int i=0; i< n-1; i++){ <--- outer loop
 for (int j=i; j<n-1-i; j++){ <--- inner loop
 int temp = a[i][j]; <--- do the swapping
 a[i][j] = a[n-1-j][i];
 a[n-1-j][i] = a[n-1-i][n-1-j];
 a[n-1-i][n-1-j] = a[j][n-1-i];
 a[j][n-1-i] = temp;
 }
 }
 return a;
 }
 }

The Russian Information and Cultural Center in Baku hosted Easter Charity Bazaar on April 21-22, Trend Life reports.
A fascinating event, organized by the Russian embassy in Azerbaijan and the Baku and Caspian eparchy of the Russian Orthodox Church, brought together MPs, representatives of the Culture and Tourism Ministry as well as diplomats and public figures.
The Easter Charity Bazaar aimed to collect funds for orphan children. The charity included wide range of events, as visitors viewed works of Azerbaijani painters, woodcarving craftsmen, handmade jewelries, and tasted Easter cakes.
The event program also included a charity lottery. All money from the Easter Bazaar will be directed to the needs of orphans.
The most active participants of the event were handed the letters of thanks from representative office of Rossotrudnichestvo in Azerbaijan.
Azerbaijan enjoys a tolerant atmosphere for different nations and religions. The national policy is defined on the principles of tolerance and coexistence of various nationalities, ethnic groups and religious minorities. Many religious confessions co-exist there. There are 1,834 mosques, 12 churches and 6 synagogues functioning in Azerbaijan.
The government has created all conditions for religious worship in the country.
Easter is the time when Christians celebrate the Resurrection of Christ, which is observed in March or April. It's celebrated on the first Sunday following the first full moon which is on or after March 21st.
The Sunday before Easter is Palm Sunday and the last three days are Maundy Thursday or Holy Thursday, Good Friday and Holy Saturday. Many churches hold special services on Easter Sunday.
The coloring eggs in bright and vibrant colors, egg rolling contest as well as preparation of Easter cake is an essential part of this spring celebration.
World nations celebrate the holiday differently. For instance, in Russia, the neighbor or loved one of a person pierces the branch of the soft blooms, kept on the latter's shoulder.
In the Czech Republic, the males of a family spank females with a homemade whip decorated with ribbons. The spanking is lighthearted and is believed to bring health over the next year.
"Sprinkling" is a popular Hungarian Easter Monday tradition, in which boys playfully sprinkle perfume, cologne or water over young women's head, and ask for a kiss.
One very famous U.K. Easter tradition is the giving out of 'Maundy Money' by the Queen on Maundy Thursday. Centuries ago it was tradition that the reigning King or Queen would wash the feet of a few of poor people, the number of people being the same as the monarch's age. This was to remember that Jesus washed his disciples feet before the Last Supper.

wal-e Simple Continuous Archiving for Postgres WAL-E Disaster Recovery =======================.. contents:: Table of Contents Introduction ------------ WAL-E is a program designed to perform continuous archiving of PostgreSQL WAL files and manage the use of pg_start_backup and pg_stop_backup. To correspond on using WAL-E or to collaborate on its development, do not hesitate to send mail to the mailing list at _EMAIL_. Github issues are also currently being used to track known problems, so please feel free to submit those. Primary Commands and Concepts ----------------------------- WAL-E has four critical operators: * backup-fetch * backup-push * wal-fetch * wal-push Of these, the "push" operators send things to storage and "fetch" operators get things from storage. "wal" operators send/get write ahead log, and "backup" send/get a hot backup of the base database that WAL segments can be applied to. All of these operators work in a context of three important environment-variable based settings: * AWS_ACCESS_KEY_ID or WABS_ACCOUNT_NAME * AWS_SECRET_ACCESS_KEY or WABS_ACCESS_KEY * WALE_S3_PREFIX or WALE_WABS_PREFIX For Swift the following environment variables are needed: * SWIFT_AUTHURL * SWIFT_TENANT * SWIFT_USER * SWIFT_PASSWORD * WALE_SWIFT_PREFIX With the exception of AWS_SECRET_ACCESS_KEY and WABS_ACCESS_KEY, all of these can be specified as arguments as well. The AWS_* variables are the standard access-control keying system provided by Amazon, where the WABS_* are the standard access credentials defined by Windows Azure. The WALE_S3_PREFIX, WALE_WABS_PREFIX and WALE_SWIFT_PREFIX (_PREFIX) variables can be thought of as a context whereby this program operates on a single database cluster at a time. Generally, for any one database the _PREFIX will be the same between all four operators. This context-driven approach attempts to help users avoid errors such as one database overwriting the WAL segments of another, as long as the _PREFIX is set uniquely for each database. Use whichever variable is appropriate for the store you are using... IMPORTANT:: Ensure that all servers have different _PREFIXes set. Reuse of a value between two servers will likely cause unrecoverable backups. Dependencies ------------ * python (>= 2.6) * lzop * psql (>= 8.4) * pv This software also has Python dependencies; installing with setup.py will attempt to resolve them: * gevent>=0.13.1 * boto>=2.6.0 * azure>=0.7.0 * python-swiftclient>=1.8.0 * python-keystoneclient>=0.4.2 * argparse, if not on Python 2.7 It is possible to use WAL-E without the dependencies of back-end storage one does not use installed: the imports for those are only performed if the storage configuration demands their use. Backend Blob Store ------------------ The storage backend is determined by the defined _PREFIX. Prefixes with the scheme ''s3'' will be directed towards S3, those with the scheme ''wabs'' will be directed towards Windows Azure Blob Service, and those with the scheme ''swift'' will be directed towards an OpenStack Swift installation. Example S3 Prefix: s3://some-bucket/directory/or/whatever Example WABS Prefix: wabs://some-container/directory/or/whatever Example OpenStack Swift Prefix: swift://some-container/directory/or/whatever Examples -------- Pushing a base backup to S3:: $ AWS_SECRET_ACCESS_KEY=... wal-e \ -k AWS_ACCESS_KEY_ID \ --s3-prefix=s3://some-bucket/directory/or/whatever \ backup-push /var/lib/my/database Sending a WAL segment to WABS:: $ WABS_ACCESS_KEY=... wal-e \ -a WABS_ACCOUNT_NAME \ --wabs-prefix=wabs://some-bucket/directory/or/whatever \ wal-push /var/lib/my/database/pg_xlog/WAL_SEGMENT_LONG_HEX Push a base backup to Swift:: $ WALE_SWIFT_PREFIX="swift://my_container_name" \ SWIFT_AUTHURL="http://my_keystone_url/v2.0/" \ SWIFT_TENANT="my_tennant" \ SWIFT_USER="my_user" \ SWIFT_PASSWORD="my_password" wal-e \ backup-push /var/lib/my/database It is generally recommended that one use some sort of environment variable management with WAL-E: working with it this way is less verbose, less prone to error, and less likely to expose secret information in logs. At this time, AWS_SECRET_ACCESS_KEY and WABS_ACCESS_KEY are the only secret values, and recording it frequently in logs is not recommended. The tool has never and should never accept secret information in argv to avoid process table security problems. However, the user running PostgreSQL (typically 'postgres') must be able to run a program that can access this secret information, as part of its archive_command_... _archive_command: _URL_ envdir_, part of the daemontools_ package is one recommended approach to setting environment variables. One can prepare an envdir-compatible directory like so:: # Assumption: the group is trusted to read secret information # S3 Setup $ umask u=rwx,g=rx,o= $ mkdir -p /etc/wal-e.d/env $ echo "secret-key-content" > /etc/wal-e.d/env/AWS_SECRET_ACCESS_KEY $ echo "access-key" > /etc/wal-e.d/env/AWS_ACCESS_KEY_ID $ echo's3://some-bucket/directory/or/whatever' > \ /etc/wal-e.d/env/WALE_S3_PREFIX $ chown -R root:postgres /etc/wal-e.d # Assumption: the group is trusted to read secret information # WABS Setup $ umask u=rwx,g=rx,o= $ mkdir -p /etc/wal-e.d/env $ echo "secret-key-content" > /etc/wal-e.d/env/WABS_ACCESS_KEY $ echo "access-key" > /etc/wal-e.d/env/WABS_ACCOUNT_NAME $ echo 'wabs://some-container/directory/or/whatever' > \ /etc/wal-e.d/env/WALE_WABS_PREFIX $ chown -R root:postgres /etc/wal-e.d After having done this preparation, it is possible to run WAL-E commands much more simply, with less risk of accidentally using incorrect values:: $ envdir /etc/wal-e.d/env wal-e backup-push... $ envdir /etc/wal-e.d/env wal-e wal-push... envdir is conveniently combined with the archive_command functionality used by PostgreSQL to enable continuous archiving. To enable continuous archiving, one needs to edit ''postgresql.conf'' and restart the server. The important settings to enable continuous archiving are related here:: wal_level = archive # hot_standby in 9.0 is also acceptable archive_mode = on archive_command = 'envdir /etc/wal-e.d/env wal-e wal-push %p' archive_timeout = 60 Every segment archived will be noted in the PostgreSQL log... WARNING:: PostgreSQL users can check the pg_settings table and see the archive_command employed. Do not put secret information into postgresql.conf for that reason, and use envdir instead. A base backup (via ''backup-push'') can be uploaded at any time, but this must be done at least once in order to perform a restoration. It must be done again if any WAL segment was not correctly uploaded: point in time recovery will not be able to continue if there are any gaps in the WAL segments... _envdir: _URL_ _daemontools: _URL_ Pulling a base backup from S3:: $ sudo -u postgres bash -c \ "envdir /etc/wal-e.d/pull-env wal-e \ --s3-prefix=s3://some-bucket/directory/or/whatever \ backup-fetch /var/lib/my/database LATEST" This command makes use of the "LATEST" pseudo-name for a backup, which queries S3 to find the latest complete backup. Otherwise, a real name can be used:: $ sudo -u postgres bash -c \ "envdir /etc/wal-e.d/pull-env wal-e \ --s3-prefix=s3://some-bucket/directory/or/whatever \ backup-fetch \ /var/lib/my/database base_LONGWALNUMBER_POSITION_NUMBER" One can find the name of available backups via the experimental ''backup-list'' operator, or using one's remote data store browsing program of choice, by looking at the ''PREFIX/basebackups_NNN/...'' directory. It is also likely one will need to provide a ''recovery.conf'' file, as documented in the PostgreSQL manual, to recover the base backup, as WAL files will need to be downloaded to make the hot-backup taken with backup-push. The WAL-E's ''wal-fetch'' subcommand is designed to be useful for this very purpose, as it may be used in a ''recovery.conf'' file like this:: restore_command = 'envdir /etc/wal-e.d/env wal-e wal-fetch "%f" "%p"'.. WARNING:: If the archived database contains user defined tablespaces please review the ''backup-fetch'' section below before utilizing that command. Primary Commands ---------------- ''backup-push'', ''backup-fetch'', ''wal-push'', ''wal-fetch'' represent the primary functionality of WAL-E and must reside on the database machine. Unlike ''wal-push'' and ''wal-fetch'' commands, which function as described above, the''backup-push

Onda is a decorative textile piece that purifies the air.
It is constructed of fabric with a thin coating based on copper-doped titanium dioxide. When combined with this chemical coating, the textile uses daylight to create a reaction with pollution such as soot and odor, transforming them into harmless water molecules. Users can track the air quality by lightly pressing on Onda's fabric. This activates a light that will remain slow and calm while the air is clean, but become quick and frenzied when sensing pollution. Users can also momentarily boost air purification by pressing and holding the piece, lighting the frame to emit ultraviolet light, the most efficient method of rapid air purification. With interchangeable textiles and designs, Onda unites life-enhancing technology with personal expression.

|'Life in 1810' is topic of program offered at County Museum on September 8|
|Written by George Browning|
|Tuesday, 04 September 2012 00:00|
A veteran speaker and re-enactor will bring to life one of his favorite topics, "Pioneer Life in 1810," at the Scott County Heritage Center and Museum on Saturday, September 8.
The free event at 2 p.m. that day is offered as part of Pigeon Roost Remembered Day, an observance of the 200th anniversary of the Pigeon Roost Massacre in which 24 men, women and children were killed by Indians on September 3, 1812.
Kevin Stonerock has brought history to life for thousands of children, young people and adults. His living history program will be performed in authentic period clothing in the first-person style. His "Hoosier pioneer" is a character compiled from several different historical accounts of the period from 1770 to 1810. It centers around the life of Andrew Amonett, a frontiersman of the Indiana Territory.
Complete with tall tales, Stonerock's presentation deals with various aspects of frontier life and dangers faced in the Indiana Territory just before the start of the War of 1812. Topics include trapping, militia service, Indian affairs, tools, weapons and frontier clothing.
Stonerock has performed for 30 years and presented over 3,500 programs. He wrote, directed and performed in "Plum Creek Anthology," which is presented annually in Vevay.
There is no charge for attending his program at the museum. Visitors are asked to bring lawn chairs to enjoy the performance in comfort on the museum's front steps.

Switch quickly between apps
When you're using your iPhone, iPad, or iPod touch, you can switch quickly from one app to another. When you return to an app, you can pick up right where you left off. Multitasking doesn't slow down the performance of the foreground app or drain battery life too much.
Here's how you switch quickly between apps:
- Double-click the Home button to display recently used apps.
- Swipe left or right to find the app you want use.
- Tap the app to open it.
Allow apps to refresh in the background
Some apps will run for a short period of time before they're set to a suspended state. This means they're not actively in use, open, or taking up system resources. When you return to these apps, they'll open instantly.
Some apps can continue to run in the background. You can allow these apps to refresh themselves by turning on Background App Refresh. This settings lets apps check for new content and download updates, or retrieve updated content in the background when they receive push notifications.
To save battery, apps running in the background refresh at certain times, like when your device is connected to Wi-Fi, plugged into a power source, or being actively used. iOS learns patterns based on how you use your device and tries to predict when an app running in the background should refresh. It also learns when the device is typically inactive, like at night, to help keep apps from refreshing when you're not using your device. Apps can also schedule background refreshing based on your location.

Fact Check: Is Chocolate Really Going 'Extinct' by 2050?
An alarming recent report by Business Insider claimed that chocolate would be extinct 40 years from now.
The story, which went viral, claimed that cacao plants are slated to disappear due to warmer weather and poor moisture conditions by as early as 2050.
Although climate change is an issue that concerns everybody, the report may not be entirely accurate.
The later half of the report talked about a new technology called CRISPR which seeks to tweak DNA of cacao plants to prevent diseases that are a potential threat to the production of chocolate.
Scientists at the University of California are teaming up with Mars, best known for their Snickers bars, to try to save the crop before it's too late, the report said, adding that the initiative will be headed by Myeong-Je Cho, the director of plant genomics at the Innovative Genomics Institute at UC Berkeley.
Soon after the Business Insider article was published, a press release by UC Berkeley clarified the matter and said:
Brian Staskawicz, Professor of Plant and Microbial Biology who works with Cho to generate sustainable crops from climate change and plant pathogens said, "Cacao can be afflicted with several devastating conditions. We're developing CRISPR editing technologies to alter the DNA in cacao plants to become more resistant to both viral and fungal diseases."
The BI report also referred to an NOAA report from 10 February 2016, which actually said that the leading producers are Côte d'Ivoire, Ghana, and Indonesia "will experience a 3.8°F (2.1°C) increase in temperature by 2050, and a marked reduction in suitable cultivation area" under a "business as usual scenario, quoting the 'Intergovernmental Panel on Climate Change (IPCC) Climate Change 2014: Impacts, Adaptation, and Vulnerability' report.
However, there are several other regions where cacao is cultivate such as Brazil and Ecuador, Cameroon, Papua New Guinea, etc.
The authors continued, "These changes in climatic suitability are predicted to take place over a time period of almost 40 years, so they will mostly impact the next rather than the current generation of cocoa trees and farmers. In other words, there is time for adaptation."
So although our favourite chocolate isn't going to disappear like the report said, unfavourable weather conditions may affect its production and its price if we don't take global warming seriously.

Starting blocks are a device used in the sport of track and field by sprint athletes to hold their feet at the start of a race so they don't slip as they push out at the sound of the gun. For most levels of competition, including all high level International competition, starting blocks are now mandatory equipment for the start of sprint races.
Prior to their invention, runners would dig holes in the dirt track. Trowels were provided at the start of races. This was not the most consistent or stable system. It also was destructive to the track surface with the holes having to be filled for subsequent runners.
Wood was the first material used, with some tracks having permanently placed wooden starting blocks with golden structures at the start line. Portable blocks were held by long metal spikes that needed to be pounded into the ground. These devices evolved to metal blocks. The common blocks of the 1960s were heavy and adjusted by screws that were frequently broken or became rusted over the years. Lighter weight blocks were made of sheet metal.
The rubberized surfaces of new All-weather running tracks that became common starting in the 1970s, made the old blocks even less secure. Original Tartan tracks left long holes to secure the blocks but most tracks required blocks to be held by small spikes similar to the ones used in shoes. Block slippage was common enough, it is an allowable loophole in the rules to recall the start of a race, without calling a "false start" against an athlete. In some amateur settings, such as high school track, since block slippage is much more common due to lower quality track surface material and/or starting blocks' spike quality, it is a commonly accepted practice to allow another person (usually a teammate) to sit on the ground behind the starting block and place their feet behind each block, using their leg power to further reduce the chance for the blocks to slip back upon the runner launching out of them.
Modern blocks used for world records now must have sensors that detect the pressure from the athlete and can be used to time their reaction to the starting gun. Athletes who react faster than 100/1000ths of a second (one tenth of a second) can be charged with a false start and the race recalled. Many also carry electronic speakers so the sound of the gun arrives at the ears of the athletes at exactly the same time.


Navigating the New Threatscape: Understanding MavenGate's Impact on Java and Android Security
Ensar Seker
5 min readJan 24, 2024
In the complex landscape of mobile application security, the threat of supply chain attacks looms large, posing significant risks to both Java and Android applications. This vulnerability represents a sophisticated method of exploiting the supply chain, mainly targeting Maven-based technologies, including Gradle, widely used in mobile app development.
_URL_
MavenGate exposes the potential for attackers to inject malicious code into applications by hijacking dependencies, a threat that extends far beyond the Android ecosystem. With the increasing reliance on these technologies in major projects, understanding MavenGate's mechanics, impact, and defense strategies becomes crucial for developers, security professionals, and stakeholders in the mobile application industry. This article delves into the intricacies of MavenGate, offering insights into how it operates, its widespread implications, and effective measures to safeguard against such vulnerabilities.
Understanding MavenGate
MavenGate represents a significant vulnerability in the supply chain of Java and Android applications. It specifically targets Maven-based technologies, such as Gradle, a popular build automation tool. This attack method exploits how these technologies handle dependencies, turning a standard development practice into a potential security nightmare.
At the heart of MavenGate lies a vulnerability that allows attackers to intercept and manipulate dependencies. When attackers gain control over these dependencies, they can inject code into applications, resulting in security breaches. The consequences of such an attack are extensive, as it can jeopardize the application and its entire development process. This could potentially expose data. Compromise the broader infrastructure of the company involved.
MavenGate's impact is alarming, especially considering the widespread use of Maven and Gradle in developing mobile applications. The vulnerability exposes a critical gap in the security of the application development process, calling for immediate attention and action from the developer community.
Methodology of MavenGate Attacks
MavenGate attacks follow a calculated methodology, capitalizing on the vulnerabilities within the dependency management system. The attack begins with the identification of abandoned dependencies within known repositories. These dependencies are no longer maintained, making them prime targets for exploitation.
Exploiting Abandoned Dependencies: Attackers search for these abandoned dependencies and purchase the corresponding domain names. Once in control of these domains, they can assert rights over the groupId associated dependency by creating a DNS TXT record. This process essentially hijacks the dependency, placing it under the attacker's control.
Repository Priority Exploitation: In many development environments, dependencies are searched and downloaded based on the order of repository declarations. Attackers take advantage of this by ensuring that their malicious repository is prioritized. This could lead to downloading compromised dependencies even when legitimate versions exist in other repositories.
Through these methods, attackers can infiltrate the build process of applications, introducing malicious code without the knowledge of developers. This highlights the vulnerability of relying on external dependencies, especially those that are not actively maintained.

The Scale of Vulnerability and Affected Projects
The MavenGate vulnerability presents a significant threat, not just in theory but in its practical implications across numerous projects. Oversecured's research revealed startling statistics that underline the severity of this issue:
 - Statistics on vulnerabilities revealed that attackers could intercept and manipulate a sizable portion of dependencies. This statistic is particularly concerning for projects with numerous direct and transitive dependencies, as it drastically increases the likelihood of a vulnerability.
 - Impact on Major Projects: MavenGate's reach extends to many high-profile companies and projects. Reports were sent to over 200 companies, including tech giants like Google, Facebook, and Amazon, indicating the widespread nature of this vulnerability. These companies' reliance on Maven-based technologies means that the potential for exploitation is not just a hypothetical risk but a pressing concern.
The vulnerability's scope demonstrates the critical need for awareness and action in the face of such supply chain attacks. It emphasizes the importance of vigilant dependency management and the need for robust security practices in developing Java and Android applications.

Defense Strategies Against MavenGate
Given the significant risks MavenGate poses, it's crucial to implement robust defense strategies. While there are existing mechanisms to protect against such vulnerabilities, they come with their own set of challenges.
Existing Defense Mechanisms
 1. File Hash Checking: This involves verifying the hash sums of files injected into the project. While effective for static dependencies, it falls short when updating library versions, leaving room for artifact spoofing.
 2. Digital Signature Verification: Using .asc files to check the digital signatures of dependencies is another method. However, it requires dependencies to publish their public key in advance, and developers must specify this key in their project's gradle/verification-metadata.xml file.
Challenges in Implementation
 - Complexity and Lack of Standardization: The process of verifying digital signatures is complex and lacks a standardized approach across different repositories.
 - Incomplete Adoption: Many dependencies do not publish digital signatures, and even fewer developers implement this verification level in their projects.
Developers, library maintainers, and repository administrators must understand these defense mechanisms' nuances and limitations. By adopting and advocating for more rigorous security practices, including regular audits of dependencies and proactive vulnerability assessments, the community can enhance its defenses against MavenGate and similar supply chain attacks.
Future Implications and Recommendations
The MavenGate vulnerability highlights the need for a more robust and updated system for signing and verifying dependencies in Java and Android applications. Moving forward, several key recommendations and considerations emerge for different stakeholders in the software development and security ecosystem:
For Developers
 - Vigilance is crucial. Regularly review and update dependencies, ensuring they are from trusted and actively maintained sources.
 - Despite their complexity, implement rigorous verification processes, including file hash checking and digital signature verification.
For Library Developers
 - Maintain control over project domains to prevent hijacking.
 - Ensure all versions of libraries are properly signed and that keys are accessible on public servers.
For Repositories
 - Consider mandatory configurations for deployments and reject improperly configured releases.
 - Implement more stringent controls for dependency updates and changes.
For the Broader Community
 - There's a need to rethink the current PGP signing system. A more streamlined and less centralized approach could enhance security.
 - Developers should declare the dependencies and the public key hashes, enhancing accountability and traceability.
As the software development landscape continues to evolve, so too must the approaches to security. The lessons from MavenGate should catalyze industry-wide changes, promoting more secure and resilient practices in managing dependencies.

The MELC Statement: reimagining learning as intercultural engagement (PDF 2.26MB) was developed in 2017 and has been endorsed by the education sector heads. It builds on the scoping paper – towards a position statement and strategy (2016, PDF 332KB), and describes an orientation and goals for education in linguistic and cultural diversity. The process of development was collaborative and informed by current research, with strategic input from educational sectors and a broad range of professional educational and community organisations.
The statement comprises:
- a vision; goals for learners outlining the intercultural capabilities and dispositions that all children and young people need to develop
- an elaboration of two key ideas about learners and learning as intercultural engagement
- suggested approaches for teachers, leaders and education sectors to realise this vision.
The MELC believes that work in this area requires a shift in understanding and that it is this conceptual shift that will lead to change in practice. The shift is towards an orientation to teaching and learning that positions students as participants engaging in diversity rather than as observers of diversity. The statement recognises the crucial role of languages, as well as reinforcing a whole of curriculum perspective that involves all educators.
The MELC Statement has resonated with principals, who are key contributors to the process of change. The statement is being seen as a focal resource for teacher professional learning.

family development program
The Family Development Program is the core program of SAFP, and marked the origin of our organization. Poor families in India are supported by regular monthly assistance for a sustainable livelihood.
Donations for the Family developmentProgram are forwarded through SAFP India office to our partners - the DSSSs (Diocesan Social Service Societies), then to the community-based Sanghams (grassroots people's organizations), and finally into the bank accounts of the recipient families. The families use these funds for necessities and many save a portion of this assistance for future needs.
There are three variables regarding the program and how it operates:
- The accuracy and integrity of the family's designation as needy
- The way in which the families spend the monthly funds is reflected by their most pressing needs (i.e. medicine, food or education of the children)
- The adequacy and duration of the assistance
The families are chosen in a participatory manner by the local Sangham based on priority of need. The names of the chosen families are then sent to the DSSS offices for review and finalization. Once families are approved, photos of the families are taken, and profiles are provided explaining the needs. The photos and profiles are forwarded to the SAFP India office for a final inspection before being sent to the SAFP office in Canada. They are recorded and stored until linked with a Canadian partner family, individual, group, etc.
Two Phased Approach on Poverty Alleviation:
- To meet immediate needs such as food, clothing, medicine or education
- To encourage each family assisted to become self-reliant and productive within the context of their local and general economy
- Provide basic human needs (food, medicine, shelter)
- Cover some of the educational costs of children so they can attend school
- Offer skills development opportunities for parents
- Enhance employability through training
- Provide means for these families to own livestock to have an improved diet and to give them an asset
- Assist families in financing entrepreneurial initiatives such as small retail stores called petty shops, bicycle repair centres, teashops, fishing businesses, etc.
- Reduces their indebtedness
- Improves their living conditions
- Reduces the burden on single parents such as widows and widowers as well as abandoned women
- Augments present income for an immediate improvement in their standard of living
- Provides avenues for subsidies and bank loans that would not normally be available to the poor
- Provides a built-in support system with their local Sangham
SAFP promises six years support to each family. After six years, if it is deemed necessary by the local Sangham or committee that the assistance must be extended for a while longer (due to extenuating circumstances such as the death of the main earner, raising a child with physical or mental challenges, etc.) the assistance will be made available.
More than 50,000 families have been assisted to become self-reliant. At present more than 12800 families are being assisted on a monthly basis. Some residents in SAFP's 25 Homes of Healing receive monthly assistance toward their living expenses, medical care or educational costs.
SAFP's Family-to-Family Program operates in the following states of India:
Andhra Pradesh, Karnataka, Kerala, Maharashtra and Tamil Nadu.
$20 a month or $240 yearly will assist a family. A minimum of $60 (3 months) support is needed to start assistance
- $1,440 (72 months) will support a family(ies) for 6 years
- $5,000 bursary will support a family(ies) for 20 years
If you wish to assist a family Click here to DONATE
You can correspond with the family in India directly. When writing letters to your family, please use only the address that appears on the profile sent to you by SAFP. This is located near the top of the profile as highlighted in the picture below. The family will write at least two letters a year, via interpreters.

The UKK 2 km Walk-Test
The UKK walk test (UKK are the initials for Urho Kaleka Kekkonen, founder of the UKK Institute in Tampere/Finland) makes it possible under certain assumptions to determine the approximately max. cardio respiratory efficiency (VO2 max) and therefore the physical condition of the subject. The UKK-walk test is perfectly suitable as a fitness check for fitness clubs or for athletes at schools for example. On the basis of this result a Fitness-Index is calculated with the help of a complex formula taking age, height, weight, test duration and Heart-Rate into consideration, which tells us whether the physical condition of the subject is above or below average. The value of 100 as the average serves as the base. If somebody's index-value is 90 then his physical condition is slightly below average. An index-value of 110 on the other hand would be above average.
The test explains itself by its name. In order to perform the test after having done some warming up and some stretching walk for 2 km as fast as possible (Do Not run!). It is important to keep the walking speed as high as is needed for the subject to achieve 80% of their max. Heart-Rate ( 220 – age). The test duration and heart-rate are measured immediately after finishing the 2 km distance.
As soon as the 2 km distance has been absolved the speed gets reduced to half the speed at the end of the test (2000 m). The Running-Machine operates as described under point "Manual-Mode" (the UP/DOWN-keys are in operation again) with one exception:
The display INDEX instead of indicating the wattage and energy consumption, indicates the test result (calculation following). The LED INDEX is flashing (top right hand side).
The test-result is the index-value which is calculated as follows (according to sex):
INDEX VALUE = 420 + A x 0,2
– (T x 0.19338 + HR x 0.56 + [W : (H2) x 2.6])
INDEX VALUE = 304 + A x 0.4
– (T x 0.1417 + HR x 0.32 + [W : (H2) x 1.1])
A = Age in years
T = Time = neede for 2 km in seconds
HR = HeartRate = average heart rate during the test in bpm
W = Weight in kg
H = Height in cm
Male, Age: 50 years
Weight: 105 kg / Height: 188 cm
Duration of test: 17:34 = 1054 seconds
Heart rate at m: 500 = 158, 1000 = 156,
1500 = 160 and 2000 = 155
Average (158 + 156 + 160 + 155) : 4 = 157 bpm
420 + 50 x 0.2 – (1054 x 0.19338 + 157 x 0.56
+ (105 : (1,882) x 2.6)) = 420
+ 10 - (203.8 + 87.9 + 29.7 x 2.6) = 430
– 368,9 = 61
An index-value of less than 70 is a result quite below average (average=100). Conclusion: Our subject is in need of some indurance training.
Basically the test is suitable for all physically healthy persons between the age of 20 and 65. The results will be less accurate with people with overweight. Athletes usually do not reach the required heart-rate when performing the test. The results will also be less accurate with elderly people.
First it has to be mentioned that the UKK-Test has not been designed for individual tests but for a larger amount of subjects. i.e. testing of a crowd of people at the same time by sending them off in 1/2 minute intervals on the 2 km-distance track. Therefore originally the UKK-Test has not been designed as a typical test for the running machine.
Advantages of performing the ukk walk-test on the running-machine: Being able to measure the precise time and distance of the test (it is exactly 2 km) and Heart-Rate control during the test. Direct test documentation via the printer interface.

If you are interested in joining the Beta for this feature, please contact your Customer Success Manager (CSM).
Pivot Columns Tile
 Pivot.png
The Pivot tile lets you "pivot" or de-normalize data in tables using key-value pairs, transforming a single column with multiple rows into multiple columns in a single row.
Note: If you create a table that reaches the 1500 column limit, you will receive an error. You must reduce the number of columns to continue running your Magic ETL DataFlow.
Example
For example, the Pivot tile converts data in this format...
... to data in this format...
... using this configuration:
To configure the Pivot tile,
 1. Click the Pivot tile in the canvas.
 2. (Optional) Rename the tile by clicking , then entering the name you want.
 3. Enter the name of the key column you want to pivot into new column headers.
 For example, "Product".
 4. Select the column to use to group the row values of the new columns.
 For example, "Month".
 5. For each new column you want to create from the key column, do the following:
 1. Enter the name of the new column header.
 For example, "Product A".
 2. Enter a value from the key column that represents the column header to be pivoted.
 For example, "A".
 3. Select the value column to use to fill the row value of the new column.
 4. For example, "Sales".
 Note: For each column you add to be uncollapsed, select the same value column.
 5. (Conditional) If you want to add another column, then click Add Column.
Tip: You can preview the data transformed by a tile by running a preview, clicking the tile in the canvas, then clicking the Preview tab.
Unpivot Tile
Unpivot.png
The Unpivot tile lets you "unpivot" or "normalize" data in tables, transforming multiple columns in a single row into a single column with multiple rows. This action is useful only for unpivoting data in which the number of columns stays the same. If you add another column of data to the original file, this action does not unpivot the new column.
Example
For example, the Unpivot tile converts data in this pivoted format...

... to data in this format...
... using this configuration:
To configure the Unpivot tile,
 1. Click the Unpivot tile in the canvas.
 2. (Optional) Rename the tile by clicking , then entering the name you want.
 3. Enter the name of the column you want to create to contain the column headings from the columns to unpivot.
 For example, "Product".
 4. Enter the name of the column you want to create to contain the row values from the columns to be unpivoted.
 For example, "Sales".
 5. For each column you want to unpivot, do the following:
 1. Select a column to normalize.
 For example, "Product A".
 2. Enter a value representing the column header to be normalized.
 The value appears in the row of the new column. For example, "A".
 3. (Conditional) If you want to unpivot another column, then click Add Column.
Tip: You can preview the data transformed by a tile by running a preview, clicking the tile in the canvas, then clicking the Preview tab.

Rotation Equivariant Networks via Conic Convolution and the DFT
Sep 27, 2018 ICLR 2019 Conference Withdrawn Submission readers: everyone
 - Abstract: Performance of neural networks can be significantly improved by encoding known invariance for particular tasks. Many image classification tasks, such as those related to cellular imaging, exhibit invariance to rotation. In particular, to aid convolutional neural networks in learning rotation invariance, we consider a simple, efficient conic convolutional scheme that encodes rotational equivariance, along with a method for integrating the magnitude response of the 2D-discrete-Fourier transform (2D-DFT) to encode global rotational invariance. We call our new method the Conic Convolution and DFT Network (CFNet). We evaluated the efficacy of CFNet as compared to a standard CNN and group-equivariant CNN (G-CNN) for several different image classification tasks and demonstrated improved performance, including classification accuracy, computational efficiency, and its robustness to hyperparameter selection. Taken together, we believe CFNet represents a new scheme that has the potential to improve many imaging analysis applications.
 - Keywords: deep learning, rotation equivariance, bioimaging analysis
 - TL;DR: We propose conic convolution and the 2D-DFT to encode rotation equivariance into an neural network.

Jewish Federations of North America Overview
The Jewish Federations of North American (JFNA) brings together 148 Federations and 300 Network Communities to maximize their impact as the central address of North America Jewry. Collectively among the top 10 charities in the world, it secures and manages $16 billion in endowment assets. Each year JFNA raises over $900 million through the Annual Campaign and emergency campaigns, and distribute over $2 billion from foundations and endowments. JFNA provides services that build the capacity of local Jewish communities and help Federations learn from one another, build affinity groups, and provide training, collateral materials and seed funding for innovation.
Union for Reform Judaism Overview
The Union for Reform Judaism provides vision and leadership to Reform Jews and congregations on spiritual, ethical, social justice, and management issues. It provides programmatic support to Reform Jewish congregations and offers opportunities for individual growth and identity that few congregations could provide by themselves. This includes camps and Israel programs for youth, study kallot and North American and regional biennials.
