In this post we’ll be taking a look at several examples of data exploration using the diamonds
dataset in the tidyverse library.1
When investigating variance within a single variable, ask:
- Which values are most common, most rare, and why?
- Does this match your expectations?
- Are there any unusual patterns, and what are the possible explanations?
- If there are clusters of observations, how are those observations similar or different?
Example 1: Use a histogram to visualize the distribution of a variable. Here we observe the distribution of the carat (weight) of diamonds.
Example 2: Play with the binwidth of histograms to reveal different patterns in the data. In this example, we get a more accurate view of the distribution of carat.
Example 3: Play with the x-axis and y-axis limits to identify outliers. In this example, there are some very high values of the “x” variable, a measure of a diamond’s dimensions, which could indicate data entry errors.
Note that in ggplot2, coord_cartesian()
keeps truncated values while xlim(), ylim()
discards them.
When investigating covariance between two variables, ask:
- Could this pattern be due to random chance?
- What is the relationship implied by the pattern, and how strong is it?
- What other variables might affect the relationship?
- Does the relationship change if you look at subgroups of data?
Case 1: A Categorical and a Continuous Variable
Example 1: Use geom_freqpoly()
to overlay multiple histograms by density. Here we can see multiple histograms of carat, split by cut.
Example 2: Another way to visualize the relationship is to create a boxplot, order the variables, and flip the axes. This is illustrated with the relationship between car class and highway miles per gallon via the mpg dataset.
Example 3: In cases where there are a lot of outliers, boxplots may not be as useful. Instead, we can use a letter value plot. Here we have a good view of the density of observations when relating cut and price of diamonds.
Example 4: The violin plot is another great way to compare density distributions among different categories. This is a different way to represent the data from the previous graph.
Case 2: Two Categorical Variables
Example 1: We can use geom_count
to map both categorical variables and display their frequency with the size of a point in a grid. In this example, we can see the distribution of observations between diamond cut and color.
Example 2: A heat map can also come in handy when comparing density of observations between two categorical variables. Again, we can see the distribution of observations between diamond cut and color.
Case 3: Two Continuous Variables
Example 1: The scatterplot is a classic way to compare continuous variables. For example, here we examine the relationship between diamond carat and price.
Example 2: We can also bin variables in two dimensions, using the fill color to represent frequency of observations.
Example 3: Another option is to bin only one continuous variables so that it behaves like a categorical variable. Here, we bin carat.
Example 4: This is the same graph, except the width of the boxplot is proportional to the number of points.
Example 5: This is again the same graph, but each box now contains approximately the same number of points.

It was a nice hybrid approach to music, where , probably, some of the riffing was a little too obvious," said Thielemann. "Some parts are really elegant but a lot of times the chord progression is kind of ridiculous, and people may be doing it on purpose. It's more embarrassing than anything." The results, added McLeod, are sound, but that's not what excites Thielemann.

document.body.scrollTop: 0px
Naive demonstration of the most basic pull to refresh implementation.
Pulling down and releasing beyond a certain threshold will trigger a refresh (in this demo, nothing actually refreshes, but watch the output above for some basic status indication to mimic this).
It relies on browsers (mainly Safari/iOS) that "overscroll" – allowing users to scroll down even when they're already at the top of the document – and the fact that touch events fire even during scrolling.
This implementation doesn't work universally, as not all browsers overscroll – some even trigger their own "pull to reload" functionality instead (such as Chrome/Android).

Overview
MDS, or mobile dispatch server, is the Sana developed middleware layer designed to act as an intermediary between the Sana mobile client and an EMR or other backend. The stock MDS source code also includes a lightweight web interface as an alternative backend for storing and accessing data through a web browser. The alternative backend, or standalone MDS, is not intended to be a replacement for a full EMR.
System Requirements
- Linux Host - We recommend and support Ubuntu 14.04 LTS. All additional requirements below are available for installation using the package manager. Additional details for installing manually on an Ubuntu host are available in the doc directory of the source.
- Git
- Python 2.7
- PILPython Imaging Library
- Django 1.6
- django-piston 0.2.3
- Django Extensions
- python-lxml
- python-libxml2
- python cjson
- python-mysql and/or other python database connector-e.g. python-sqlite3
Source Code
Source code for MDS is available on GitHub.
https://github.com/SanaMobile/sana.mds.git
Building
No additional build instructions are required.
Running
Use the standard Django admin functions to run the app as a server, django-admin.py. For production use, we recommend running MDS on Apache or other server. Sample Apache conf files are included in the source. Please consult the Django documentation for more information.

See the pcName parameter of the xTaskCreate() and xTaskCreateStatic() API
functions for information on setting
the text name of a task.
|
- Returns:
- If a task that has the name passed in
pcNameToQuery can be located then the handle of
the task is returned, otherwise NULL is
returned.
task.h
volatile TickType_t xTaskGetTickCount( void );
This function cannot be called from an ISR. Use xTaskGetTickCountFromISR()
instead.
- Returns:
- The count of ticks since vTaskStartScheduler
was called.
task.h
volatile TickType_t xTaskGetTickCountFromISR( void );
A version of xTaskGetTickCount() that can be called from an ISR.
- Returns:
- The count of ticks
since vTaskStartScheduler was called.
task.h
BaseType_t xTaskGetSchedulerState( void );
- Returns:
- One of the following
constants (defined within task.h):
taskSCHEDULER_NOT_STARTED,
taskSCHEDULER_RUNNING,
taskSCHEDULER_SUSPENDED.
INCLUDE_xTaskGetSchedulerState or
configUSE_TIMERS must be set to 1 in
FreeRTOSConfig.h for this function to be
available.
task.h
UBaseType_t uxTaskGetNumberOfTasks( void
);
- Returns:
- The number of tasks
that the RTOS kernel is currently managing.
This includes all ready, blocked and suspended
tasks. A task that has been deleted but not yet
freed by the idle task will also be included in
the count.
task.h
void vTaskList( char *pcWriteBuffer );
configUSE_TRACE_FACILITY and configUSE_STATS_FORMATTING_FUNCTIONS must be
defined as 1 in FreeRTOSConfig.h for this function to be available.
See the configuration section for more information.
NOTE: This function will disable interrupts for its duration. It is not intended
for normal application runtime use but as a debug aid.
vTaskList() calls uxTaskGetSystemState(),
then formats the raw data generated by
uxTaskGetSystemState() into a human readable (ASCII) table that shows the state
of each task, including the task's stack high water mark (the smaller the high
water mark number the closer the task has come to overflowing its stack).
Click here to see an example of the output generated.
In the ASCII table the following letters are used to denote the state of a task:
- 'B' - Blocked
- 'R' - Ready
- 'D' - Deleted (waiting clean up)
- 'S' - Suspended, or Blocked without a
timeout
vTaskList() is a utility function provided for convenience only. It is not
considered part of the kernel. See vTaskGetRunTimeStats()
for a utility function that generates a similar table of run time task utilisation
information.
- Parameters:
-
| pcWriteBuffer |
A buffer into
which the above mentioned details will
be written, in ASCII form. This buffer
is assumed to be large enough to
contain the generated report.
Approximately 40 bytes per task should
be sufficient. |
task.h
void vTaskStartTrace( char
* pcBuffer, unsigned long ulBufferSize );
[The function relates to the legacy trace utility - which was removed in FreeRTOS V7.1.0 - users may find the newer
Trace Hook Macros easier and more powerful to use.]
Starts a RTOS kernel activity trace. The trace logs the identity of which task is running when.
The trace file is stored in binary format. A separate DOS utility called convtrce.exe is used to convert this into a tab delimited text file which can be viewed and plotted in a spread sheet.
- Parameters:
-
| pcBuffer |
The buffer into
which the trace will be written. |
| ulBufferSize |
The size of
pcBuffer in bytes. The trace will
continue until either the buffer in
full, or ulTaskEndTrace() is
called. |
task.h
unsigned long
ulTaskEndTrace( void );
[The function relates to the legacy trace utility - which was removed in FreeRTOS V7.1.0 - users may find the newer
Trace Hook Macros easier and more powerful to use.]
Stops an RTOS kernel activity trace. See vTaskStartTrace().
- Returns:
- The number of bytes that have been written
into the trace buffer.
task.h
void vTaskGetRunTimeStats( char *pcWriteBuffer );
See the Run Time Stats page for a full
description of this feature.
configGENERATE_RUN_TIME_STATS and configUSE_STATS_FORMATTING_FUNCTIONS must
both be defined as 1 for this function to be available. The application must
also then provide definitions for portCONFIGURE_TIMER_FOR_RUN_TIME_STATS() and
portGET_RUN_TIME_COUNTER_VALUE to configure a peripheral timer/counter
and return the timers current count value respectively. The counter
should be at least 10 times the frequency of the tick count.
NOTE: This function will disable interrupts for its duration. It is
not intended for normal application runtime use but as a debug aid.
vTaskGetRunTimeStats() calls uxTaskGetSystemState(),
then formats the raw data generated by uxTaskGetSystemState() into a human
readable (ASCII) table that shows the amount of time each task has spent in the
Running state (how much CPU time each task has consumed). The data is provided
as both an absolute and a percentage value. The resolution of the absolute value
is dependent on the frequency of the run time stats clock provided by the application.
vTaskGetRunTimeStats() is a utility function provided for convenience only. It is not
considered part of the kernel. See vTaskList()
for a utility function that generates information on the state of each task.
- Parameters:
-
| pcWriteBuffer |
A buffer into
which the execution times will be
written, in ASCII form. This buffer is
assumed to be large enough to contain
the generated report. Approximately 40
bytes per task should be
sufficient. |

Mimic (1997) A movie review by Michael J. Legeros Copyright 1997 by Michael J. Legeros
(Dimension) Directed by Guillermo Del Toro Written by John Sayles, Steven Soderbergh, Matthew Robbins Cast Mira Sorvino, Jeremy Northam, Charles Dutton, Giancarlo Giannini, F. Murray Abraham, Josh Brolin, Alexander Goodwin MPAA Rating "R" (presumably for violence and gore) Running Time 105 minutes Reviewed at The Wynnsong, Durham, NC (23AUG97)
==
Yet another sucky sci-fi spook-fest, this one stars Mira Sorvino, bless her heart, as a Big Apple entomologist who creates a hybrid insect to combat a cockroach-borne epidemic-in-the-making. Her supposedly sterile solution works wonders until, three years later, the bugs return, having mutated into human-sized, human-mimicking monsters. For the first hour, while we wait for a good glimpse of the creatures, the various characters (Sorvino's, her character's husband, her character's husband's partner, a couple of kids, a shoe shine man, the shoe shine man's autistic son, and a feisty transit worker) poke around the city's subway tunnels, unafraid of any dark, damp, obviously creature-infested corners. (Don't these people watch horror movies?) When the bugs finally *do* appear, believability gets zapped-- rewiring decades-old subway circuitry on the fly?-- but we finally get some action and a little blood and an adorably grimy Sorvino, whose deadpan reaction to the appearance of a particular creature may be the single best howler of the summer: "Ohmigod, it's the male." Stylishly directed by Guillermo Del Toro (CRONOS).

Brazilian soccer team sponsored by Red Bull gets promoted
SAO PAULO (AP) - A small soccer team from outside Sao Paulo will play in Brazil’s top division next year with a deep-pocketed sponsor behind it.
Bragantino, which last played in the country’s main soccer competition in 1998, secured its spot in next year’s Brazilian championship by beating Guarani 3-1. But it will head into next season with a new name, Red Bull Bragantino.
The club received an investment of nearly $15 million from the energy drink maker this season, a figure that will reportedly double for 2020.
Bragantino, which reached the Brazilian league’s final in 1991 but lost to Sao Paulo, leads its current league by eight points with five matches to play.

146 security flaws found in pre-loaded Android apps around the globe
Fortunately, most of these aren't on Canadian devices
by Brad BennettA U.S. based cybersecurity firm has published a report detailing 146 new Android security flaws found within first-party apps and services.
While a vast majority of these services are from Asian manufacturers, some global heavyweights like Samsung and Asus are included in the roundup.
What’s concerning about this report is that these are pre-installed apps and services, so users can’t get rid of the affected code on their phones.
The Cybersecurity firm is called Kryptowire and was contracted by the U.S. Department of Homeland Security.
Most of the affected devices are brands that don’t usually make it to Canada, such as Xiaomi, BQ, Doogee and more.
Wired has reported that Samsung claims two of the vulnerabilities on its devices are the handiwork of contracted developers, and the other four are rendered harmless by the Android Security Framework.
Kryptowire doesn’t believe Samsung’s claim, according to Wired.

Bootstrap Strength Meter is intended to demonstrate the usage of Password Score - a JavaScript library used to give a realistic estimate of the strength of a password.
Consider donating to support development.
Note that documentation is not complete yet. Check boostrap-strength-meter
for details!
First, all dependencies need to be included: jQuery, Twitter Bootstrap and Password Score.
 <link rel="stylesheet" type="text/css" href="docs/css/bootstrap.css">
Depending on the used configuration options, the required markup may vary - see Drivers & Options. For this example we assume that the strength of the password should be displayed as text:
<form class="form-horizontal">
 Email
 <input type="text" placeholder="Email ..." class="form-control" />

 Password
 <input type="text" placeholder="Password ..." class="form-control" id="example-getting-started-input" />

 <button class="btn btn-primary">Login</button>

 </form>
The plugin offers several so called drivers - options that allow to display the password strength differently. The following example shows how to use the text
driver:

text driver |
|
|---|---|
The text driver will display the password strength as text - ranging from "ridiculus" over "good" to "very strong" and applying corresponding classes: .text-danger , .text-warning and .text-success . The text driver offers the below configuration options. |
|
container |
The container the text is displayed in. Usually, a Per default, the text will be appended to the password input's parent element. |
hierarchy |
This option allows to control the text begin displayed and the class being applied on its parent hierarchy: { '0': ['text-danger', 'ridiculous'], '25': ['text-danger', 'very weak'], '50': ['text-warning', 'weak'], '75': ['text-warning', 'good'], '100': ['text-success', 'strong'], '125': ['text-success', 'very strong'] } The keys refer to the score needed to change the text and its corresponding class. This means that a password with a score between 10 and 20 will be declared as "very weak". For this purpose it is useful to understand what the score means: A score of $h$ means that a maximum of $2^h$ attempts are necessary to crack the password. The higher $h$ the stronger the password. An example is shown below (where relatively weak passwords are declared "strong"):

| Current Version | Code Name |

| v0.1.0 | Arborvitae |
At this time, only Windows is supported. We recommend to use ExpressCPP together with Visual Studio.
Download the necessary files (one .lib
and some .h
files) from the release page.
Create or use existing C++ project. Right click the project in solution view, and include the path to the header and lib files. Under C/C++ > General > Additional Include Directories
, edit to add the path that contains the the header files. Similarly, under Linker > General > Additional Library Directories
, edit to add the path that contains the lib files.
ExpressCPP requires Ws2_32.lib
which should be already installed on your computer.
First, create a Express
instance. We recommend use singleton pattern but it is not required.
#include "CExpress\express.h"
#ifdef _DEBUG
#pragma comment(lib, "CExpress\\express_debug.lib")
#else
#pragma comment(lib, "CExpress\\express_release.lib")
#endif
int main() {
CExpress::Express ex;
}
The above example, I put all the headers and lib files under directory CExpress
that is at the same level as this code file. _DEBUG
flag will be defined if you set "Debug" in the configuration manager.
using namespace CExpress
is ok if you know it does not create any ambiguity.
Then, we can create a controller:
ex.route("GET", "/", [=](Request & req, Response & res) {
res.body = "
Hello World
";
res.headers["Content-Type"] = "text/html; charset=utf-8";
});
If the request url match multiple controllers, only the first one we find will be executed.
Lastly, start the server:
ex.start(8080);
That's it! The complete code for hello world program is
#include "CExpress\express.h"
#ifdef _DEBUG
#pragma comment(lib, "CExpress\\express_debug.lib")
#else
#pragma comment(lib, "CExpress\\express_release.lib")
#endif
int main() {
CExpress::Express ex;
ex.route("GET", "/", [=](Request & req, Response & res) {
res.body = "
Hello World
";
res.headers["Content-Type"] = "text/html; charset=utf-8";
});
ex.start(8080);
}
Note that you need to set the content type to html if you are passing back html to the client. Because you are taking reference of
Request
andResponse
it is unnecessary to return anything. Also,ex.start(8080)
needs to be the last line of your program.
Create a middleware by
ex.use([=](Request & req, Response & res) {
// process the request and response here
});
The execution of middleware is the same as your declaration order.
Crate an error handler like this:
ex.onerror("404", [=](Request & req, Response & res) {
// process error here
});
If you define multiple error handlers for the same error code, the one that actually runs will be random. We are internally using
unordered_map
.

--- title: Resume in RMarkdown author: Sneha Kannan date: '2020-03-31' slug: resume-in-rmarkdown categories: - Career tags: - R - RMarkdown - Career draft: no ---
One of my professional goals this year is to use blogging as a medium to practice skills related to data science. As a first step, I have made my resume using pagedown. Thanks to Nick Strayer and his blogpost, I could create my resume in RStudio. The blog post was detailed and simplified the process for me. I added the Skills section in the Sidebar and used the Font Awesome icons. Once I had the various sections of my resume compiled in the spreadsheet as explained in the blogpost, I tweaked the CSS files for some formatting changes and had the resume saved as a PDF.
Here is the github repository containing the code that was used to generate my resume.

10 more ISIS-K militants surrender to Afghan Special Forces in Nangarhar
by Khaama PressA group of ten ISIS Khurasan militants surrendered to Afghan Special Forces in eastern Nangarhar province, days after hundreds of ISIS militants surrendered to security forces in this province.
The Special Operations Corps said in a statement late on Friday that the militants surrendered to Special Forces in Achin district.
The statement further added that the ISIS militants also handed over 10 Ak-47 assault rifles to Special Forces.
The Special Operations Corps also added that a small group of ISIS militants are still active in Achin district who have no option other than to surrender or they would be eliminated.
This comes as the Ministry of Defense had earlier announced that more than 600 ISIS militants and their family members surrendered to Afghan forces in eastern Nangarhar province.

As pictures became clearer and imaging techniques became cheaper, photographers used this newfound technology to document the war. Many photographers would prepare, expose, and develop the slides in a matter of minutes using the collodion imaging system. Of all wars, the civil war was the first to have extensive image documentation, and so it was the first one could study the effects of it.
Photography influenced the war mainly through the press. With photography about, normal civilians would not just hear about the dreadful carnage of the war, but see it as well. This fuelled pacifist minds and made it more real for everyone involved.
Matthew Brady, often credited to be the father of photojournalism, took thousands of photos of the war. Brady even managed to photograph 18 of the 19 presidents at the time. He didn't take all of thos photos himself, of course. He had the help of over 17 paid assistants.
After the war, he was in poverty, very much like all other famous artists. During the war, he openly marketed to parents of soldiers for portraits of their children in uniform.

| Prev | Up | Appendix E. Release Notes | Next |
Release date: 2003-11-17
Major changes in this release:
In previous releases, IN/NOT IN subqueries were joined to the upper query by sequentially scanning the subquery looking for a match. The 7.4 code uses the same sophisticated techniques used by ordinary joins and so is much faster. An IN will now usually be as fast as or faster than an equivalent EXISTS subquery; this reverses the conventional wisdom that applied to previous releases.
In previous releases, rows to be grouped had to be sorted first. The 7.4 code can do GROUP BY without sorting, by accumulating results into a hash table with one entry per group. It will still use the sort technique, however, if the hash table is estimated to be too large to fit in sort_mem.
In previous releases, hash joins could only occur on single keys. This release allows multicolumn hash joins.
Prior releases evaluated queries using the explicit JOIN syntax only in the order implied by the syntax. 7.4 allows full optimization of these queries, meaning the optimizer considers all possible join orderings and chooses the most efficient. Outer joins, however, must still follow the declared ordering.
The entire regular expression module has been replaced with a new version by Henry Spencer, originally written for Tcl. The code greatly improves performance and supports several flavors of regular expressions.
Simple SQL functions can now be inlined by including their SQL in the main query. This improves performance by eliminating per-call overhead. That means simple SQL functions now behave like macros.
Previous releases allowed only IPv4 connections, and the IP data types only supported IPv4 addresses. This release adds full IPv6 support in both of these areas.
Several people very familiar with the SSL API have overhauled our SSL code to improve SSL key negotiation and error recovery.
In previous releases, B-tree index pages that were left empty because of deleted rows could only be reused by rows with index values similar to the rows originally indexed on that page. In 7.4, VACUUM records empty index pages and allows them to be reused for any future index rows.
The information schema provides a standardized and stable way to access information about the schema objects defined in a database.
The commands FETCH and MOVE have been overhauled to conform more closely to the SQL standard.
These cursors are also called holdable cursors.
The new protocol adds error codes, more status information, faster startup, better support for binary data transmission, parameter values separated from SQL commands, prepared statements available at the protocol level, and cleaner recovery from COPY failures. The older protocol is still supported by both server and clients.
While previous libpq releases already supported threads, this release improves thread safety by fixing some non-thread-safe code that was used during database connection startup. The configure option --enable-thread-safety must be used to enable this feature.
A new full-text indexing suite is available in contrib/tsearch2.
The new autovacuum tool in contrib/autovacuum monitors the database statistics tables for INSERT/UPDATE/DELETE activity and automatically vacuums tables when needed.
Many array limitations have been removed, and arrays behave more like fully-supported data types.
A dump/restore using pg_dump is required for those wishing to migrate data from any previous release.
Observe the following incompatibilities:
The server-side autocommit setting was removed and reimplemented in client applications and languages. Server-side autocommit was causing too many problems with languages and applications that wanted to control their own autocommit behavior, so autocommit was removed from the server and added to individual client APIs as appropriate.
Error message wording has changed substantially in this release. Significant effort was invested to make the messages more consistent and user-oriented. If your applications try to detect different error conditions by parsing the error message, you are strongly encouraged to use the new error code facility instead.
Inner joins using the explicit JOIN syntax might behave differently because they are now better optimized.
A number of server configuration parameters have been renamed for clarity, primarily those related to logging.
FETCH 0 or MOVE 0 now does nothing. In prior releases, FETCH 0 would fetch all remaining rows, and MOVE 0 would move to the end of the cursor.
FETCH and MOVE now return the actual number of rows fetched/moved, or zero if at the beginning/end of the cursor. Prior releases would return the row count passed to the command, not the number of rows actually fetched or moved.
COPY now can process files that use carriage-return or carriage-return/line-feed end-of-line sequences. Literal carriage-returns and line-feeds are no longer accepted in data values; use \r and \n instead.
Trailing spaces are now trimmed when converting from type char(n) to varchar(n) or text. This is what most people always expected to happen anyway.
The data type float(p) now measures p in binary digits, not decimal digits. The new behavior follows the SQL standard.
Ambiguous date values now must match the ordering specified by the datestyle setting. In prior releases, a date specification of 10/20/03 was interpreted as a date in October even if datestyle specified that the day should be first. 7.4 will throw an error if a date specification is invalid for the current setting of datestyle.
The functions oidrand
,
oidsrand
, and
userfntest
have been removed. These
functions were determined to be no longer useful.
String literals specifying time-varying date/time values, such
as 'now' or 'today' will
no longer work as expected in column default expressions; they
now cause the time of the table creation to be the default, not
the time of the insertion. Functions such as
now()
, current_timestamp
, or
current_date
should be used instead.
In previous releases, there was special code so that strings
such as 'now' were interpreted at
INSERT time and not at table creation time, but
this work around didn't cover all cases. Release 7.4 now
requires that defaults be defined properly using functions such
as now()
or current_timestamp
. These
will work in all situations.
The dollar sign ($) is no longer allowed in operator names. It can instead be a non-first character in identifiers. This was done to improve compatibility with other database systems, and to avoid syntax problems when parameter placeholders ($n) are written adjacent to operators.
Below you will find a detailed account of the changes between release 7.4 and the previous major release.
Allow IPv6 server connections (Nigel Kukard, Johan Jordaan, Bruce, Tom, Kurt Roeckx, Andrew Dunstan)
Fix SSL to handle errors cleanly (Nathan Mueller)
In prior releases, certain SSL API error reports were not handled correctly. This release fixes those problems.
SSL protocol security and performance improvements (Sean Chittenden)
SSL key renegotiation was happening too frequently, causing poor SSL performance. Also, initial key handling was improved.
Print lock information when a deadlock is detected (Tom)
This allows easier debugging of deadlock situations.
Update /tmp socket modification times regularly to avoid their removal (Tom)
This should help prevent /tmp directory cleaner administration scripts from removing server socket files.
Enable PAM for Mac OS X (Aaron Hillegass)
Make B-tree indexes fully WAL-safe (Tom)
In prior releases, under certain rare cases, a server crash could cause B-tree indexes to become corrupt. This release removes those last few rare cases.
Allow B-tree index compaction and empty page reuse (Tom)
Fix inconsistent index lookups during split of first root page (Tom)
In prior releases, when a single-page index split into two pages, there was a brief period when another database session could miss seeing an index entry. This release fixes that rare failure case.
Improve free space map allocation logic (Tom)
Preserve free space information between server restarts (Tom)
In prior releases, the free space map was not saved when the postmaster was stopped, so newly started servers had no free space information. This release saves the free space map, and reloads it when the server is restarted.
Add start time to pg_stat_activity (Neil)
New code to detect corrupt disk pages; erase with zero_damaged_pages (Tom)
New client/server protocol: faster, no username length limit, allow clean exit from COPY (Tom)
Add transaction status, table ID, column ID to client/server protocol (Tom)
Add binary I/O to client/server protocol (Tom)
Remove autocommit server setting; move to client applications (Tom)
New error message wording, error codes, and three levels of error detail (Tom, Joe, Peter)
Add hashing for GROUP BY aggregates (Tom)
Make nested-loop joins be smarter about multicolumn indexes (Tom)
Allow multikey hash joins (Tom)
Improve constant folding (Tom)
Add ability to inline simple SQL functions (Tom)
Reduce memory usage for queries using complex functions (Tom)
In prior releases, functions returning allocated memory would not free it until the query completed. This release allows the freeing of function-allocated memory when the function call completes, reducing the total memory used by functions.
Improve GEQO optimizer performance (Tom)
This release fixes several inefficiencies in the way the GEQO optimizer manages potential query paths.
Allow IN/NOT IN to be handled via hash tables (Tom)
Improve NOT IN (subquery) performance (Tom)
Allow most IN subqueries to be processed as joins (Tom)
Pattern matching operations can use indexes regardless of locale (Peter)
There is no way for non-ASCII locales to use the standard indexes for LIKE comparisons. This release adds a way to create a special index for LIKE.
Allow the postmaster to preload libraries using preload_libraries (Joe)
For shared libraries that require a long time to load, this option is available so the library can be preloaded in the postmaster and inherited by all database sessions.
Improve optimizer cost computations, particularly for subqueries (Tom)
Avoid sort when subquery ORDER BY matches upper query (Tom)
Deduce that WHERE a.x = b.y AND b.y = 42 also means a.x = 42 (Tom)
Allow hash/merge joins on complex joins (Tom)
Allow hash joins for more data types (Tom)
Allow join optimization of explicit inner joins, disable with join_collapse_limit (Tom)
Add parameter from_collapse_limit to control conversion of subqueries to joins (Tom)
Use faster and more powerful regular expression code from Tcl (Henry Spencer, Tom)
Use bit-mapped relation sets in the optimizer (Tom)
Improve connection startup time (Tom)
The new client/server protocol requires fewer network packets to start a database session.
Improve trigger/constraint performance (Stephan)
Improve speed of col IN (const, const, const, ...) (Tom)
Fix hash indexes which were broken in rare cases (Tom)
Improve hash index concurrency and speed (Tom)
Prior releases suffered from poor hash index performance, particularly for high concurrency situations. This release fixes that, and the development group is interested in reports comparing B-tree and hash index performance.
Align shared buffers on 32-byte boundary for copy speed improvement (Manfred Spraul)
Certain CPU's perform faster data copies when addresses are 32-byte aligned.
Data type numeric reimplemented for better performance (Tom)
numeric used to be stored in base 100. The new code uses base 10000, for significantly better performance.
Rename server parameter server_min_messages to log_min_messages (Bruce)
This was done so most parameters that control the server logs begin with log_.
Rename show_*_stats to log_*_stats (Bruce)
Rename show_source_port to log_source_port (Bruce)
Rename hostname_lookup to log_hostname (Bruce)
Add checkpoint_warning to warn of excessive checkpointing (Bruce)
In prior releases, it was difficult to determine if checkpoint was happening too frequently. This feature adds a warning to the server logs when excessive checkpointing happens.
New read-only server parameters for localization (Tom)
Change debug server log messages to output as DEBUG rather than LOG (Bruce)
Prevent server log variables from being turned off by non-superusers (Bruce)
This is a security feature so non-superusers cannot disable logging that was enabled by the administrator.
log_min_messages/client_min_messages now controls debug_* output (Bruce)
This centralizes client debug information so all debug output can be sent to either the client or server logs.
Add Mac OS X Rendezvous server support (Chris Campbell)
This allows Mac OS X hosts to query the network for available PostgreSQL servers.
Add ability to print only slow statements using log_min_duration_statement (Christopher)
This is an often requested debugging feature that allows administrators to see only slow queries in their server logs.
Allow pg_hba.conf to accept netmasks in CIDR format (Andrew Dunstan)
This allows administrators to merge the host IP address and netmask fields into a single CIDR field in pg_hba.conf.
New read-only parameter is_superuser (Tom)
New parameter log_error_verbosity to control error detail (Tom)
This works with the new error reporting feature to supply additional error information like hints, file names and line numbers.
postgres --describe-config now dumps server config variables (Aizaz Ahmed, Peter)
This option is useful for administration tools that need to know the configuration variable names and their minimums, maximums, defaults, and descriptions.
Add new columns in pg_settings: context, type, source, min_val, max_val (Joe)
Make default shared_buffers 1000 and max_connections 100, if possible (Tom)
Prior versions defaulted to 64 shared buffers so PostgreSQL would start on even very old systems. This release tests the amount of shared memory allowed by the platform and selects more reasonable default values if possible. Of course, users are still encouraged to evaluate their resource load and size shared_buffers accordingly.
New pg_hba.conf record type hostnossl to prevent SSL connections (Jon Jensen)
In prior releases, there was no way to prevent SSL connections if both the client and server supported SSL. This option allows that capability.
Remove parameter geqo_random_seed (Tom)
Add server parameter regex_flavor to control regular expression processing (Tom)
Make pg_ctl better handle nonstandard ports (Greg)
New SQL-standard information schema (Peter)
Add read-only transactions (Peter)
Print key name and value in foreign-key violation messages (Dmitry Tkach)
Allow users to see their own queries in pg_stat_activity (Kevin Brown)
In prior releases, only the superuser could see query strings using pg_stat_activity. Now ordinary users can see their own query strings.
Fix aggregates in subqueries to match SQL standard (Tom)
The SQL standard says that an aggregate function appearing within a nested subquery belongs to the outer query if its argument contains only outer-query variables. Prior PostgreSQL releases did not handle this fine point correctly.
Add option to prevent auto-addition of tables referenced in query (Nigel J. Andrews)
By default, tables mentioned in the query are automatically added to the FROM clause if they are not already there. This is compatible with historic POSTGRES behavior but is contrary to the SQL standard. This option allows selecting standard-compatible behavior.
Allow UPDATE ... SET col = DEFAULT (Rod)
This allows UPDATE to set a column to its declared default value.
Allow expressions to be used in LIMIT/OFFSET (Tom)
In prior releases, LIMIT/OFFSET could only use constants, not expressions.
Implement CREATE TABLE AS EXECUTE (Neil, Peter)
Make CREATE SEQUENCE grammar more conforming to SQL:2003 (Neil)
Add statement-level triggers (Neil)
While this allows a trigger to fire at the end of a statement, it does not allow the trigger to access all rows modified by the statement. This capability is planned for a future release.
Add check constraints for domains (Rod)
This greatly increases the usefulness of domains by allowing them to use check constraints.
Add ALTER DOMAIN (Rod)
This allows manipulation of existing domains.
Fix several zero-column table bugs (Tom)
PostgreSQL supports zero-column tables. This fixes various bugs that occur when using such tables.
Have ALTER TABLE ... ADD PRIMARY KEY add not-null constraint (Rod)
In prior releases, ALTER TABLE ... ADD PRIMARY would add a unique index, but not a not-null constraint. That is fixed in this release.
Add ALTER TABLE ... WITHOUT OIDS (Rod)
This allows control over whether new and updated rows will have an OID column. This is most useful for saving storage space.
Add ALTER SEQUENCE to modify minimum, maximum, increment, cache, cycle values (Rod)
Add ALTER TABLE ... CLUSTER ON (Alvaro Herrera)
This command is used by pg_dump to record the cluster column for each table previously clustered. This information is used by database-wide cluster to cluster all previously clustered tables.
Improve automatic type casting for domains (Rod, Tom)
Allow dollar signs in identifiers, except as first character (Tom)
Disallow dollar signs in operator names, so x=$1 works (Tom)
Allow copying table schema using LIKE subtable, also SQL:2003 feature INCLUDING DEFAULTS (Rod)
Add WITH GRANT OPTION clause to GRANT (Peter)
This enabled GRANT to give other users the ability to grant privileges on a object.
Add ON COMMIT clause to CREATE TABLE for temporary tables (Gavin)
This adds the ability for a table to be dropped or all rows deleted on transaction commit.
Allow cursors outside transactions using WITH HOLD (Neil)
In previous releases, cursors were removed at the end of the transaction that created them. Cursors can now be created with the WITH HOLD option, which allows them to continue to be accessed after the creating transaction has committed.
FETCH 0 and MOVE 0 now do nothing (Bruce)
In previous releases, FETCH 0 fetched all remaining rows, and MOVE 0 moved to the end of the cursor.
Cause FETCH and MOVE to return the number of rows fetched/moved, or zero if at the beginning/end of cursor, per SQL standard (Bruce)
In prior releases, the row count returned by FETCH and MOVE did not accurately reflect the number of rows processed.
Properly handle SCROLL with cursors, or report an error (Neil)
Allowing random access (both forward and backward scrolling) to some kinds of queries cannot be done without some additional work. If SCROLL is specified when the cursor is created, this additional work will be performed. Furthermore, if the cursor has been created with NO SCROLL, no random access is allowed.
Implement SQL-compatible options FIRST, LAST, ABSOLUTE n, RELATIVE n for FETCH and MOVE (Tom)
Allow EXPLAIN on DECLARE CURSOR (Tom)
Allow CLUSTER to use index marked as pre-clustered by default (Alvaro Herrera)
Allow CLUSTER to cluster all tables (Alvaro Herrera)
This allows all previously clustered tables in a database to be reclustered with a single command.
Prevent CLUSTER on partial indexes (Tom)
Allow DOS and Mac line-endings in COPY files (Bruce)
Disallow literal carriage return as a data value, backslash-carriage-return and \r are still allowed (Bruce)
COPY changes (binary, \.) (Tom)
Recover from COPY failure cleanly (Tom)
Prevent possible memory leaks in COPY (Tom)
Make TRUNCATE transaction-safe (Rod)
TRUNCATE can now be used inside a transaction. If the transaction aborts, the changes made by the TRUNCATE are automatically rolled back.
Allow prepare/bind of utility commands like FETCH and EXPLAIN (Tom)
Add EXPLAIN EXECUTE (Neil)
Improve VACUUM performance on indexes by reducing WAL traffic (Tom)
Functional indexes have been generalized into indexes on expressions (Tom)
In prior releases, functional indexes only supported a simple function applied to one or more column names. This release allows any type of scalar expression.
Have SHOW TRANSACTION ISOLATION match input to SET TRANSACTION ISOLATION (Tom)
Have COMMENT ON DATABASE on nonlocal database generate a warning, rather than an error (Rod)
Database comments are stored in database-local tables so comments on a database have to be stored in each database.
Improve reliability of LISTEN/NOTIFY (Tom)
Allow REINDEX to reliably reindex nonshared system catalog indexes (Tom)
This allows system tables to be reindexed without the requirement of a standalone session, which was necessary in previous releases. The only tables that now require a standalone session for reindexing are the global system tables pg_database, pg_shadow, and pg_group.
New server parameter extra_float_digits to control precision display of floating-point numbers (Pedro Ferreira, Tom)
This controls output precision which was causing regression testing problems.
Allow +1300 as a numeric time-zone specifier, for FJST (Tom)
Remove rarely used functions oidrand
,
oidsrand
, and userfntest
functions
(Neil)
Add md5()
function to main server, already in contrib/pgcrypto (Joe)
An MD5 function was frequently requested. For more complex encryption capabilities, use contrib/pgcrypto.
Increase date range of timestamp (John Cochran)
Change EXTRACT(EPOCH FROM timestamp) so timestamp without time zone is assumed to be in local time, not GMT (Tom)
Trap division by zero in case the operating system doesn't prevent it (Tom)
Change the numeric data type internally to base 10000 (Tom)
New hostmask()
function (Greg Wickham)
Fixes for to_char()
and to_timestamp()
(Karel)
Allow functions that can take any argument data type and return any data type, using anyelement and anyarray (Joe)
This allows the creation of functions that can work with any data type.
Arrays can now be specified as ARRAY[1,2,3], ARRAY[['a','b'],['c','d']], or ARRAY[ARRAY[ARRAY[2]]] (Joe)
Allow proper comparisons for arrays, including ORDER BY and DISTINCT support (Joe)
Allow indexes on array columns (Joe)
Allow array concatenation with || (Joe)
Allow WHERE qualification expr op ANY/SOME/ALL (array_expr) (Joe)
This allows arrays to behave like a list of values, for purposes like SELECT * FROM tab WHERE col IN (array_val).
New array functions array_append
,
array_cat
, array_lower
,
array_prepend
, array_to_string
,
array_upper
, string_to_array
(Joe)
Allow user defined aggregates to use polymorphic functions (Joe)
Allow assignments to empty arrays (Joe)
Allow 60 in seconds fields of time, timestamp, and interval input values (Tom)
Sixty-second values are needed for leap seconds.
Allow cidr data type to be cast to text (Tom)
Disallow invalid time zone names in SET TIMEZONE
Trim trailing spaces when char is cast to varchar or text (Tom)
Make float(p) measure the precision p in binary digits, not decimal digits (Tom)
Add IPv6 support to the inet and cidr data types (Michael Graff)
Add family()
function to report whether address is IPv4 or IPv6 (Michael Graff)
Have SHOW datestyle generate output similar to that used by SET datestyle (Tom)
Make EXTRACT(TIMEZONE) and SET/SHOW TIME ZONE follow the SQL convention for the sign of time zone offsets, i.e., positive is east from UTC (Tom)
Fix date_trunc('quarter', ...) (Böjthe Zoltán)
Prior releases returned an incorrect value for this function call.
Make initcap()
more compatible with Oracle (Mike Nolan)
initcap()
now uppercases a letter appearing
after any non-alphanumeric character, rather than only after
whitespace.
Allow only datestyle field order for date values not in ISO-8601 format (Greg)
Add new datestyle values MDY, DMY, and YMD to set input field order; honor US and European for backward compatibility (Tom)
String literals like 'now' or
'today' will no longer work as a column
default. Use functions such as now()
,
current_timestamp
instead. (change
required for prepared statements) (Tom)
Treat NaN as larger than any other value in min()
/max()
(Tom)
NaN was already sorted after ordinary numeric values for most
purposes, but min()
and max()
didn't
get this right.
Prevent interval from suppressing :00 seconds display
New functions pg_get_triggerdef(prettyprint)
and pg_conversion_is_visible()
(Christopher)
Allow time to be specified as 040506 or 0405 (Tom)
Input date order must now be YYYY-MM-DD (with 4-digit year) or match datestyle
Make pg_get_constraintdef
support
unique, primary-key, and check constraints (Christopher)
Prevent PL/pgSQL crash when RETURN NEXT is used on a zero-row record variable (Tom)
Make PL/Python's spi_execute
interface
handle null values properly (Andrew Bosma)
Allow PL/pgSQL to declare variables of composite types without %ROWTYPE (Tom)
Fix PL/Python's _quote()
function to handle big integers
Make PL/Python an untrusted language, now called plpythonu (Kevin Jacobs, Tom)
The Python language no longer supports a restricted execution environment, so the trusted version of PL/Python was removed. If this situation changes, a version of PL/Python that can be used by non-superusers will be readded.
Allow polymorphic PL/pgSQL functions (Joe, Tom)
Allow polymorphic SQL functions (Joe)
Improved compiled function caching mechanism in PL/pgSQL with full support for polymorphism (Joe)
Add new parameter $0 in PL/pgSQL representing the function's actual return type (Joe)
Allow PL/Tcl and PL/Python to use the same trigger on multiple tables (Tom)
Fixed PL/Tcl's spi_prepare
to accept fully
qualified type names in the parameter type list
(Jan)
Add \pset pager always to always use pager (Greg)
This forces the pager to be used even if the number of rows is less than the screen height. This is valuable for rows that wrap across several screen rows.
Improve tab completion (Rod, Ross Reedstrom, Ian Barwick)
Reorder \? help into groupings (Harald Armin Massa, Bruce)
Add backslash commands for listing schemas, casts, and conversions (Christopher)
\encoding now changes based on the server parameter client_encoding (Tom)
In previous versions, \encoding was not aware of encoding changes made using SET client_encoding.
Save editor buffer into readline history (Ross)
When \e is used to edit a query, the result is saved in the readline history for retrieval using the up arrow.
Improve \d display (Christopher)
Enhance HTML mode to be more standards-conforming (Greg)
New \set AUTOCOMMIT off capability (Tom)
This takes the place of the removed server parameter autocommit.
New \set VERBOSITY to control error detail (Tom)
This controls the new error reporting details.
New prompt escape sequence %x to show transaction status (Tom)
Long options for psql are now available on all platforms
Multiple pg_dump fixes, including tar format and large objects
Allow pg_dump to dump specific schemas (Neil)
Make pg_dump preserve column storage characteristics (Christopher)
This preserves ALTER TABLE ... SET STORAGE information.
Make pg_dump preserve CLUSTER characteristics (Christopher)
Have pg_dumpall use GRANT/REVOKE to dump database-level privileges (Tom)
Allow pg_dumpall to support the options -a, -s, -x of pg_dump (Tom)
Prevent pg_dump from lowercasing identifiers specified on the command line (Tom)
pg_dump options --use-set-session-authorization and --no-reconnect now do nothing, all dumps use SET SESSION AUTHORIZATION
pg_dump no longer reconnects to switch users, but instead always uses SET SESSION AUTHORIZATION. This will reduce password prompting during restores.
Long options for pg_dump are now available on all platforms
PostgreSQL now includes its own long-option processing routines.
Add function PQfreemem
for freeing memory on
Windows, suggested for NOTIFY (Bruce)
Windows requires that memory allocated in a library be freed by
a function in the same library, hence
free()
doesn't work for freeing memory
allocated by libpq. PQfreemem
is the proper
way to free libpq memory, especially on Windows, and is
recommended for other platforms as well.
Document service capability, and add sample file (Bruce)
This allows clients to look up connection information in a central file on the client machine.
Make PQsetdbLogin
have the same defaults as
PQconnectdb
(Tom)
Allow libpq to cleanly fail when result sets are too large (Tom)
Improve performance of function PQunescapeBytea
(Ben Lamb)

Add ability to pass binary data directly to the server (Tom)
Add function PQexecPrepared
and
PQsendQueryPrepared

on updateable result sets
Allow executeBatch
on a prepared statement (Barry)
Support SSL connections (Barry)
Handle schema names in result sets (Paul Sorenson)
Add refcursor support (Nic Ferrier)
Prevent possible memory leak or core dump during libpgtcl shutdown (Tom)
Add Informix compatibility to ECPG (Michael)
This allows ECPG to process embedded C programs that were written using certain Informix extensions.
Add type decimal to ECPG that is fixed length, for Informix (Michael)
Allow thread-safe embedded SQL programs with configure option --enable-thread-safety (Lee Kindness, Bruce)
This allows multiple threads to access the database at the same time.

Trump to ask U.S. Supreme Court to review tax returns decision
by Jonathan StempelNEW YORK (Reuters) - U.S. President Donald Trump plans to ask the U.S. Supreme Court to overturn a ruling requiring his accounting firm to turn over eight years of his tax returns to New York prosecutors, setting the stage for a possible decision before the 2020 election.
Lawyers for Trump and Manhattan District Attorney Cyrus Vance said on Friday that the president intends to ask the Supreme Court by Nov. 14 to review Monday’s ruling on the tax returns by the federal appeals court in Manhattan.
Vance will oppose the request, and the parties intend to brief their positions by Nov. 25, according to the lawyers.
The timetable was disclosed in a letter filed with the federal court in Manhattan, where the lawyers asked that the case be put on hold while Trump seeks Supreme Court review.
Monday’s ruling by the 2nd U.S. Circuit Court of Appeals authorized Vance’s office to enforce a subpoena to obtain Trump’s tax returns from the accounting firm Mazars LLP.
Vance, a Democrat, sought the returns as part of a criminal probe into Trump and his family real estate business.
Trump has argued that he is immune from criminal investigations while in office.
While the appeals court did not decide that issue, it said it did not matter because Vance was seeking the tax returns from Mazars rather than from the president himself.
The Supreme Court is not required to hear Trump’s appeal. If it does, it could rule in its current term, which ends in June.
Five of the court’s nine justices are considered conservatives and were appointed by Republican presidents, including two appointed by Trump - Neil Gorsuch and Brett Kavanaugh.
Prior to becoming president, Trump had built a real estate empire with his New York-based business.
He is facing an unrelated impeachment inquiry in the Democratic-led U.S. House of Representatives.

Mercury is the smallest and innermost planet in the Solar System. Its orbit around the Sun takes only 87.97 days, the shortest of all the planets in the Solar System. It is named after the Roman deity Mercury, the messenger of the gods.
Like Venus, Mercury orbits the Sun within Earth's orbit as an inferior planet, and its apparent distance from the Sun as viewed from Earth never exceeds 28°. This proximity to the Sun means the planet can only be seen near the western horizon after sunset or eastern horizon before sunrise, usually in twilight. At this time, it may appear as a bright star-like object, but is often far more difficult to observe than Venus. The planet telescopically displays the complete range of phases, similar to Venus and the Moon, as it moves in its inner orbit relative to Earth, which recurs over its synodic period of approximately every 116 days.
The dwarf planet Pluto (with an average orbit of 39 AU (5.8 billion km; 3.6 billion mi) from the Sun) is the largest known object in the Kuiper belt. When discovered in 1930, it was considered to be the ninth planet; this changed in 2006 with the adoption of a formal definition of planet. Pluto has a relatively eccentric orbit inclined 17 degrees to the ecliptic plane and ranging from 29.7 AU (4.44 billion km; 2.76 billion mi) from the Sun at perihelion (within the orbit of Neptune) to 49.5 AU (7.41 billion km; 4.60 billion mi) at aphelion. Pluto has a 2:3 resonance with Neptune, meaning that Pluto orbits twice round the Sun for every three Neptunian orbits. Kuiper belt objects whose orbits share this resonance are called plutinos.
Charon, the largest of Pluto's moons, is sometimes described as part of a binary system with Pluto, as the two bodies orbit a barycenter of gravity above their surfaces (i.e. they appear to "orbit each other"). Beyond Charon, four much smaller moons, Styx, Nix, Kerberos, and Hydra, orbit Pluto.


1 They said that later this king went down alive to what the Greeks call Hades and there played dice with Demeter, and after winning some and losing some, came back with a gift from her of a golden hand towel.
2 From the descent of Rhampsinitus, when he came back, they said that the Egyptians celebrate a festival, which I know that they celebrate to this day, but whether this is why they celebrate, I cannot say.
3 On the day of the festival, the priests weave a cloth and bind it as a headband on the eyes of one of their number, whom they then lead, wearing the cloth, into a road that goes to the temple of Demeter; they themselves go back, but this priest with his eyes bandaged is guided (they say) by two wolves to Demeter's temple, a distance of three miles from the city, and led back again from the temple by the wolves to the same place.
