public class UIManager extends Object implements Serializable
UIManager
manages the current look and feel, the set of
available look and feels, PropertyChangeListeners
that
are notified when the look and feel changes, look and feel defaults, and
convenience methods for obtaining various default values.
LookAndFeel
and passing
it to setLookAndFeel
. The following example illustrates
setting the look and feel to the system look and feel:
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());The following example illustrates setting the look and feel based on class name:
UIManager.setLookAndFeel("javax.swing.plaf.metal.MetalLookAndFeel");Once the look and feel has been changed it is imperative to invoke
updateUI
on all JComponents
. The method SwingUtilities.updateComponentTreeUI(java.awt.Component)
makes it easy to apply updateUI
to a containment hierarchy. Refer to it for
details. The exact behavior of not invoking updateUI
after changing the look and feel is
unspecified. It is very possible to receive unexpected exceptions,
painting problems, or worse.
swing.defaultlaf
is
non-null
, use its value as the default look and feel class
name.
Properties
file swing.properties
exists and contains the key swing.defaultlaf
,
use its value as the default look and feel class name. The location
that is checked for swing.properties
may vary depending
upon the implementation of the Java platform. In Sun's implementation
the location is ${java.home}/lib/swing.properties
.
Refer to the release notes of the implementation being used for
further details.
UIManager
manages three sets of UIDefaults
. In order, they
are:
setLookAndFeel()
is invoked). The
look and feel defaults can be obtained using the getLookAndFeelDefaults()
method.
get
methods
results in checking each of the defaults, in order, returning
the first non-null
value. For example, invoking
UIManager.getString("Table.foreground")
results in first
checking developer defaults. If the developer defaults contain
a value for "Table.foreground"
it is returned, otherwise
the look and feel defaults are checked, followed by the system defaults.
It's important to note that getDefaults
returns a custom
instance of UIDefaults
with this resolution logic built into it.
For example, UIManager.getDefaults().getString("Table.foreground")
is equivalent to UIManager.getString("Table.foreground")
. Both
resolve using the algorithm just described. In many places the
documentation uses the word defaults to refer to the custom instance
of UIDefaults
with the resolution logic as previously described.
When the look and feel is changed, UIManager
alters only the
look and feel defaults; the developer and system defaults are not
altered by the UIManager
in any way.
The set of defaults a particular look and feel supports is defined
and documented by that look and feel. In addition, each look and
feel, or ComponentUI
provided by a look and feel, may
access the defaults at different times in their life cycle. Some
look and feels may agressively look up defaults, so that changing a
default may not have an effect after installing the look and feel.
Other look and feels may lazily access defaults so that a change to
the defaults may effect an existing look and feel. Finally, other look
and feels might not configure themselves from the defaults table in
any way. None-the-less it is usually the case that a look and feel
expects certain defaults, so that in general
a ComponentUI
provided by one look and feel will not
work with another look and feel.
Warning:
Serialized objects of this class will not be compatible with
future Swing releases. The current serialization support is
appropriate for short term storage or RMI between applications running
the same version of Swing. As of 1.4, support for long term storage
of all JavaBeansTM
has been added to the java.beans
package.

s representing the
LookAndFeel
implementations currently available. The
LookAndFeelInfo
objects can be used by an
application to construct a menu of look and feel options for
the user, or to determine which look and feel to set at startup

objects, LookAndFeelInfo
maintains the
class name of the LookAndFeel
class, not the actual
LookAndFeel
instance.

Narrative
John Dawson was born on 21 Dec, 1851 at Townfield Rd, Keighley Yks. His mother was Susannah Dawson formerly Smith. His father Thomas Dawson was a Warehouseman. (I applied for his Birth certificate on 5/7/1985)
He was a Master Builder. He was a Free Settler, travelling from England to Australia through South Africa, where they couldn't find any work. They arrived in Sydney Australia in 1883 on the S.S."Percussier" with a couple of his mates including George Ellis, where they found work the next day. He married Annie Ellis in 1885 at St. David's CofE in Surry Hills Sydney.
He died in 1920 age 68yrs from bowel cancer at Chelmsford Ave, Cronulla where he & his 2 sons -Tom & Selwyn had built many houses. John & Anne are buried at Woronora CofE Cemetery, Sutherland Sec BBB lot 28, with John's sister Mary Bradley.
SMH - John William Dawson - died 19 May, 1920, at his son's residence, Chelmford Ave, Cronulla, beloved husband of Ann Dawson, late of Enfield, aged 68 yrs.

CBSE- Class 10-IIT Foundation-Quadratic Equations Completing the square method (2)
Let us discuss about another way of solving a quadratic equation.
That is, by completing the square, completing the square method. In the previous videos, we have covered factorization method.
Now I'll tell you the algorithm that is used in completing the square method.
Let us apply the completing the square method to the standard form of quadratic equation.
The first step of completing the square method is to make the coefficient of X squared equal to one. What we do is we divide by the coefficient of X squared on both sides so that the coefficient of X squared becomes one.
Let's do it, and then you will understand.
Dividing the equation by A.
What do we get? AX squared by A plus BX by A plus C by A is equal to zero by A. That is nothing but zero. The coefficient of X squared here has become one.
That was our purpose of doing this step. B by AX plus C by A is equal to zero.
In the second step what we need to do is we will add and subtract half of the coefficient of X, square of half of coefficient of X.
That is B by two A. It is half of B by A squared. We need to add and subtract this thing in this equation.
X squared plus B by AX plus B by two A squared. If we add something to an equation, we need to subtract the same amount to keep the equation intact. Plus C by A is equal to zero.
I haven't made any changes to the original equation.
I've just added something and subtracted the same thing. Now, if you notice carefully, this expression has become of the form A squared plus B squared plus two AB.
We can write it as A plus B whole squared.
This expression can be written as X plus B by two A whole squared, and the rest of the expression, B by two A whole squared plus C by A is equal to zero.
We will keep this complete square on the left hand side, and let us take the rest of the things to the right hand side of the equation.
Now, let us further solve this equation.
This will become B squared by four A squared minus C by A, and this will become B squared minus four AC divided by four A squared.
Let me take another page, then I'll explain.
X plus B by two A whole squared is equal to B squared minus four AC is equal to B squared minus four AC divided by four A squared.
B squared minus four AC divided by four A squared.
Next logical step would be to take the square root. I'll get X plus B by two A is equal to plus/minus and the root B squared minus four AC divided by two A.
The entire purpose of this exercise is to get the values of X, so we'll keep X on the left hand side and take this B by two A to the right hand side. We'll change the sign. Minus B by two A plus/minus B squared minus four AC divided by two A. Here we got the values of X, so we can further simplify it.
Minus B plus/minus B squared minus four AC divided by two A.
These are the values of X that we get by completing the square method.
We'll further discuss various terms in this expression, but this is how we do solutions of quadratic equations using completing the square method.
I'll take some examples to further simplify it in further videos.


tl;dr:
- Download and install the latest
.msi

Left Ctrl
toLeft Alt
(and vice versa) in SharpKeys - Download and install AutoHotKey
- Save this script somewhere on your machine
- Double-click the downloaded script to activate it
Want a more detailed walk-through? Keep reading!
A few months ago I put together a pretty decent Windows PC, mostly for gaming. Although of course I started tinkering here and there with programming on it, and eventually decided to go full in on making it a web dev machine. The timing couldn't be perfect either, as Windows released WSL 2 recently and its performance with Docker Desktop has been incredible.
The downside though is that my day-to-day work is on a MacBook, and (although I feel alone in this) I absolutely love using Alt
instead of Ctrl
for things like copying and pasting. I figured there had to be others like me out there who have solved this, so I went searching for a solution.
There's a few different methods out there, but I found a combination of two things that were easy to set up using free software, and have performed consistently well since I added them a few weeks ago. With that being said, let's get started!
Step #1 - Switching Alt and Ctrl
The first part of this will be dedicated to swapping out our Ctrl
key for the Alt
key, which mimics the Apple keyboard Cmd
key placement. For this, you'll need to download and install a program called SharpKeys. The app is entirely open source, and you'll need to visit the releases GitHub page downloading the latest .msi
file available.
Once you have it installed, open it up and click the Add button toward the lower right. You're looking to map both the Left Ctrl key to Left Alt, and the Left Alt key to Left Ctrl. After you do that, your program's main screen should look like this:
If everything looks right, click the Write to Registry button towards the lower right to save your changes. Then, exit the application.
You can now try it out and see that your Alt and Ctrl keys have been switched! Instead of using Ctrl+C for copying, you'll now be using Alt+C. However, there's a small caveat. Because all we did was map the keys differently, keyboard shortcuts that made use of Alt
now expect to use Ctrl
.
If you're like me and use Alt+Tab to switch between windows a lot, that's where you'll notice this problem the most. Let's fix that!
Step 2 - Remapping Alt Tab
For this next step we'll need another free program, AutoHotKey. Go ahead and download the program from that link and install it on your machine. Skip through any tutorial or help requests if you'd like, we're only going to be using it with a single (and fairly short) script.
After it's been installed successfully, download the following script and save it somewhere convenient on your machine, making sure that it contains a .ahk
extension:
{% gist https://gist.github.com/aschmelyun/296ce38449aca705ead68ac76cdaa316 %}
From there, double-clicking on the file will silently start the AutoHotKey script, re-enabling your Alt+Tab window switching! ✨
Note: The above script also adds in some helpful MacOS-related keybindings for Alt+Arrow
combinations.
Extra Step - Running AutoHotKey Script on Startup
Using the method above, you'll need to double-click on the script each time your computer turns on in order for your Alt+Tab fix to start working. There's a simple workaround for this though, that will get the script starting as soon as the computer turns on.
Just follow these three simple steps:
- Press Win+R to open up the Run dialog.
- Type in
shell:startup
and press Enter, this should open up a folder window. - Copy and paste your saved
.ahk
script file into this window.
As soon as your computer boots up, your AutoHotKey script and SharpKeys modifications will start running, essentially swapping out your Windows keybindings for those on a MacOS system. 🔥
That's it! If you have any questions about the above, any issues with what was outlined, or additions that might be helpful to the AutoHotKey script I provided, please feel free to let me know. You can leave a comment below, or message me on Twitter.
Feel free to follow me on there as well, if you'd like to see fairly regular, shorter posts on web development and MacOS. You'll also see updates when I publish new video tutorials and finish writing articles.

10.4 Auxiliary Modules for File I/O
File objects supply all functionality that
is strictly needed for file I/O. There are some auxiliary Python
library modules, however, that offer convenient supplementary
functionality, making I/O even easier and handier in several
important special cases.
10.4.1 The fileinput Module
The fileinput module
lets you loop over all the lines in a list of text files. Performance
is quite good, comparable to the performance of direct iteration on
each file, since fileinput uses internal buffering
to minimize I/O. Therefore, you can use module
fileinput for line-oriented file input whenever
you find the module's rich functionality convenient,
without worrying about performance. The input
function is the main function of module fileinput,
and the module also provides a FileInput class
that supports the same functionality as the module's
functions.
Closes the whole sequence, so that iteration stops and no file
remains open.
class FileInput(files=None,inplace=0,backup='',bufsize=0)
|
|
Creates and returns an instance f of class
FileInput. Arguments are the same as for
fileinput.input, and methods of
f have the same names, arguments, and
semantics as functions of module fileinput.
f also supplies a method
readline, which reads and returns the next line.
You can use class FileInput explicitly, rather
than the single implicit instance used by the functions of module
fileinput, when you want to nest or otherwise mix
loops that read lines from more than one sequence of files.
Returns the number of lines read so far from the file now being read.
For example, returns 1 if the first line has just
been read from the current file.
Returns the name of the file being read, or None
if no line has been read yet.
input(files=None,inplace=0,backup='',bufsize=0)
|
|
Returns the sequence of lines in the files, suitable for use in a
for loop. files is a
sequence of filenames to open and read one after the other, in order.
Filename '-' means standard input
(sys.stdin). If files
is a string, it's a single filename to open and
read. If files is None,
input uses sys.argv[1:] as the
list of filenames If the sequence of filenames is empty,
input reads sys.stdin.
The sequence object that input returns is an
instance of class FileInput; that instance is also
the global state of module input, so all other
functions of module fileinput operate on the same
shared state. Each function of module fileinput
corresponds directly to a method of class
FileInput.
When inplace is false (the default),
input just reads the files. When
inplace is true, however,
input moves each file being read (except standard
input) to a backup file, and redirects standard output
(sys.stdout) to write to the file being read. This
operation lets you simulate overwriting files in-place. If
backup is a string starting with a dot,
input uses backup as
the extension of the backup files and does not remove the backup
files. If backup is an empty string (the
default), input uses extension
.bak, and deletes each backup file when the file
is closed.
bufsize is the size of the internal buffer
that input uses to read lines from the input
files. If bufsize is 0,
input uses a buffer of 8192 bytes.
Returns True or False, just
like filelineno( )= =1.
Returns True if the file now being read is
sys.stdin, otherwise False.
Returns the total number of lines read so far since the call to
input.
Closes the file now being read, so that the next line to be read will
be the first one of the following file.
10.4.2 The linecache Module
The
linecache module lets you read a given line
(specified by number) from a file with a given name. The module keeps
an internal cache, so if you need to read several lines from a file,
the operation is cheaper than opening and examining the file each
time. Module linecache exposes the following
functions.
Ensures that the module's cache holds no stale data,
but rather reflects what's on the filesystem. Call
checkcache when the files you're
reading may have changed on the filesystem, if you need to ensure
that future calls to getline return updated
information.
Drops the module's cache so that the memory can be
reused for other purposes. Call clearcache when
you don't need to perform any more reading for now.
Reads and returns the lineno line from the
text file named filename, including the
trailing \n. For any error,
getline does not raise exceptions, but rather
returns the empty string ''. If
filename is not found,
getline also looks for the file in the directories
listed in sys.path.
10.4.3 The struct Module
The
struct module lets you pack binary data into a
string, and then unpack the bytes of such a string back into the data
they represent. Such operations can be useful for various kinds of
low-level programming. Most often, you use module
struct to interpret data records from binary files
having some specified format or to prepare records to be written to
such binary files. The module's name comes from
C's keyword struct, which is
usable for related purposes. On any error, functions of module
struct raise exceptions that are instances of
exception class struct.error, the only class that
the module supplies.
Operations of module struct rely on struct format
strings, which are ordinary strings that follow a specified syntax.
The first character of a format string can specify the byte order,
size, and alignment of packed data:
- @
-
Native byte order, native data sizes, and native alignment for the
current platform; this is the default, if the first character is none
of the characters listed here (note that format P
in Table 10-2 is available only for this kind of
format string)
- =
-
Native byte order for the current platform, but standard size and
alignment
- <
-
Little-endian byte order (like Intel platforms), standard size and
alignment
- >
, !
-
Big-endian byte order (network-standard), standard size and alignment
Standard sizes are indicated in Table 10-2.
Standard alignment means that there is no forced alignment and that
explicit pad bytes are used if needed. Native sizes and alignment are
whatever the platform's C compiler uses. Native byte
order is either little-endian or big-endian, depending on the current
platform.
After the optional leading character, a format string is made up of
one or more format characters that can be preceded by an optional
count (an integer represented by its decimal digits). The possible
format characters are shown in Table 10-2. For most
format characters, the count indicates repetition (e.g.,
'3h' is exactly the same as
'hhh'). When the format character is
s or p, indicating a string,
the count is not a repetition, but rather the total number of bytes
occupied by the string. Whitespace can be freely and innocuously used
between formats, but not between a count and its format character.

Format s denotes
a fixed-length string, exactly as long as its count (the Python
string is truncated or padded with copies of the null character
'\0', if needed). Format p
denotes a Pascal-like string: the first byte is the number of
significant characters, and the characters start from the second
byte. The count indicates the total number of bytes, including the
length byte.
Module struct supplies the following functions.
Returns the size in bytes of the structure corresponding to format
string fmt.
Packs the given values according to format string
fmt and returns the resulting string.
values must match in number and types the
values required by fmt.
Unpacks binary string str according to
format string fmt and returns a tuple of
values.
len(str)
must be equal to
struct.calcsize(fmt).
10.4.4 The xreadlines Module
The
xreadlines module will be deprecated in Python
2.3. You should avoid it in Python 2.2, since directly iterating on a
file object is at least as fast. If you need to support Python 2.1,
module xreadlines and the
xreadlines method of file objects are a good
choice in terms of input performance. Module
fileinput, covered earlier in this chapter, is a
good compromise if your code needs to support many different versions
of Python, and still get good performance. The
xreadlines module supplies one function.
Accepts argument f, which must be a file
object or a file-like object with a readlines
method like that of file objects. Returns a sequence object
x that is usable in a
for statement or as the argument to built-in
functions such as filter.
x represents the same sequence of strings
as f.readlines( ), but
x does so in a lazy way, limiting memory
consumption. xreadlines is to
readlines much like xrange is
to range.

Honeybee conservation with Python
a talk by Thiago da Silva Alves
In the apidologie research area, there is one task that obliges the researcher to classify and count the contents of each comb cell in each frame. With this task is possible to control the progression of brood, bees, and food reserves. Since each frame can have thousands of cells, in most cases this task is done by a human in an approximate way, making it error-prone. The automation of this process, using image analysis represents an evolution in this field.
The honey bee is the world’s most important pollinator of food crops. Almost one-third of the food that we consume each day relies on pollination done mainly by bees. So the creation of software that helps the preservation of this species has a direct impact on our lives.
I am going to show you a few challenges we have faced, from creating comb cell detectors using OpenCV and Shapely, to developing models based on Deep Learning to classify the cell's content using the Caffe framework. With these models, we have obtained accuracy above 98% within eight different classes and solved the proposed problem.
This talk is aimed at advanced Pythonistas. (While it might be interesting for beginners we recommend them to choose another talk.)

'Europe Must Ensure Iran Oil Exports & Bank Transactions' – Iranian Deputy FM
On the side-lines of the 2019 Moscow Non-Proliferation Conference, Iran’s Deputy Foreign Minister Abbas Araghchi, in an exclusive interview with Sputnik, spoke about how the forthcoming US presidential election could affect the JCPOA.
The deputy minister explained under what conditions the US would return to the Iranian deal, as well as when Iran would return to the uranium enrichment levels that existed before the concluded deal, and what European countries should do to implement the JCPOA.
Sputnik: The US presidential election will be held next year. Some senators and presidential candidates favour a return of the US to the JCPOA. What impact do you believe the US presidential election will have on the Iran nuclear deal?
Abbas Araghchi: The US elections will not affect our programme in any way.
Sputnik: Under what circumstances do you see the possibility of the United States returning to the JCPOA? What are the conditions needed in the US to return to the agreement?
Abbas Araghchi: They must again lift all sanctions (against Iran) that they have imposed to this day.
Sputnik: When will Iran return to the uranium enrichment levels that existed before the JCPOA?
Abbas Araghchi: We will be taking action depending on the evolving situation. It is impossible to speak now of any decisions.
Sputnik: What concrete steps do you expect from Europe in order to return to implementing the deal?
Abbas Araghchi: Europe must ensure Iran's interests, the most important of which are Iran's ability to export oil as well as receive through banks payments for oil sales.


Example:
class MyClass { int val; // Method MyClass named identically to its containing class. // Likely, 'void' was added by mistake. void MyClass(int val) { this.val = val; } }
When possible, a quick-fix is provided to convert the method to a constructor:
class MyClass { int val; MyClass(int val) { this.val = val; } }
Another quick-fix is provided to rename the method.


| crashrpt | |
| A crash reporting system for Windows applications |
Count of received crash reports may depend on robustness of your software to various exceptional situations and on popularity of your software. So it's nothing unusual if you receive hundreds of error reports a day. If there are many incoming error reports, you can monitor and analyse them for the first few days after release, and prepare a hot fix release.
The purpose of the error report is to help you determine the reason of the problem and try to fix it. The keyword is 'try', because in most cases you can't fix crash reports as you usually do with normal bugs. You usually can't reproduce the error on your machine, so you can't guarantee it is fixed. So the only way to check is to make fixes in parts of code that could cause the crash most probably and to release a new version of software. For some tips on doing such code modifications, see Making Your Code Robust.
The normal scenario is that your software becomes more and more stable with each evolutional release and less and less error reports are received.
For more information about using crash description XML and crash minidump, see Using Crash Description XML and Using Crash Minidump.
For information on how to automate error report processing, see Automating Crash Report Processing.
How do I check integrity of a received error report?
You may calculate MD5 hash for your error report and compare it with the MD5 hash that is attached to the error report. When you receive error reports using HTTP connection, the MD5 hash is passed to the server-side script through the 'md5' parameter. Since CrashRpt v1.1.1., when you receive error reports using email, the MD5 hash is attached to the email.
I want the user to directly send me the stack trace, w/o me need to postprocess anything with that on my side. Does crashrpt support this somehow?
No, CrashRpt can't generate readable stack traces on the side of the user. It supports developer-side error report processing.
User-side error report processing would require you to distribute your PDB files with your software. Typically you do not distribute PDB files, because it makes someone easier to reverse-engineer your program. Our approach is developer-side post-processing. This means users send you error reports and you post-process them on your machine, where PDB files, binaries and source code is located.

SQLite is a C-language library that implements a small, fast, self-contained, high-reliability, full-featured, SQL database engine. SQLite is the most used database engine in the world. SQLite is built into all mobile phones and most computers and comes bundled inside countless other applications that people use every day. More Information... The SQLite file format is stable, cross-platform, and backwards compatible and the developers pledge to keep it that way through at least the year 2050. SQLite database files are commonly used as containers to transfer rich content between systems and as a long-term archival format for data. There are over 1 trillion (1e12) SQLite databases in active use. SQLite source code is in the public-domain and is free to everyone to use for any purpose. --- # More code ```python # Cursor is the 'interactive' method for modifying the db # You create a cursor from the connection c = conn.cursor() # Create table - tables store data. # Tables will have/can have many 'rows' representing items # Tables have columns representing data points. # Rows have 'fields' which is the value in the column # That was info610 in 4 bullets c.execute('''CREATE TABLE stocks (date text, trans text, symbol text, qty real, price real)''') # Insert a row of data c.execute("INSERT INTO stocks VALUES ('2006-01-05','BUY','RHAT',100,35.14)") # Save (commit) the changes # This ensures that all data hasn't been lost conn.commit() # We will close the connection if we are done with it. # If you haven't committed your changes, they will be lost. conn.close() ``` --- # Quick SQL overview * Query * Insert * Update * Delete ## Insert * `insert into [table] ([columns]) values ([values])` * e.g. - `INSERT INTO stocks (date, trans, symbol, qty, price) values ('2020-11-11', 'SELL', 'MKL', 30, 1500.0)` ## Query * `select [columns] from [table(s)] [WHERE [filter]] [ORDER BY columns]` * e.g. - `SELECT * FROM stocks` * e.g. - `SELECT date, symbol FROM stocks WHERE symbol = 'MKL'` We may skip update/delete for now. --- # Create a database for our movies In the interest of time, let's pick a few columns that are important. 1. id 2. Title 3. Original Title 4. Budget 5. Homepage 6. imdb_id 7. Release Date 8. Revenue 9. Runtime 10. Vote Average 11. Vote Count Create Statement to make the table `CREATE TABLE movies (id int primary key, homepage varchar, imdb_id varchar, release_date date, revenue real, runtime real, vote_average real, vote_count int);` --- From a software design standpoint, we'll build 4 components. 1.

This object has lots of database specific things in it. When we iterate (for loop) on the cursor, we get a set of 'tuples'. Tuples are a great, immutable data type, but here's how we "get" the titles: ```python for movie in result: print("Found Title: {}".format(movie[1])) ``` How do we know which index in the tuple will be which field, we 'selected *'? Trial and error is no fun.
second_query.py
Let's use a map --- # Row Factory We can override the default 'row factory' with a 'Row' factory so we can access items by column name. ```python def get_database(filename): conn = sqlite3.connect(filename) conn.row_factory = sqlite3.Row return conn ``` ```python for movie in result: print("Found Title: {}".format(movie["title"])) ``` This allows you to change the order of columns in the query without changing your subsequent code.
third_query.py
--- # Parameterizing Queries When we query records in a database, we typically want to 'find' items based on certain criteria. Whether it's a 'description' or 'title' in our Movies , or by ID to get a specific item. Here are a few example functions: --- ```python import sqlite3 import logging def dict_factory(cursor, row): d = {} for idx, col in enumerate(cursor.description): d[col[0]] = row[idx] return d def get_database(filename): conn = sqlite3.connect(filename) # Changed for a real dictionary! conn.row_factory = dict_factory return conn def search_title(descr): results = [] conn = get_database('database.sqlite3.db') c = conn.cursor() parm = "%{}%".format(descr) SELECT_QUERY = " SELECT * FROM movies WHERE title like ? LIMIT 5 " result = c.execute(SELECT_QUERY, (parm,)) for movie in result: results.append(movie) conn.commit() conn.close() return results def search_id(id): conn = get_database('database.sqlite3.db') c = conn.cursor() SELECT_QUERY = " SELECT * FROM movies WHERE id = ?;" result = c.execute(SELECT_QUERY, (id, )) movie = result.fetchone() conn.commit() conn.close() return movie if __name__ == "__main__": my_movie = search_id(15602) print("15602") print(my_movie) my_movie = search_id(11862) print("11862") print(my_movie) my_movies = search_title('grumpier') print("grumpier") for movie in my_movies: print(f"{movie['id']}: {movie['title']} ") my_movies = search_title('star') print("star") for movie in my_movies: print(f"{movie['id']}: {movie['title']} ") ``` --- # Too much code Lots of repetition. The database connection code is repeated over and over.. and will be for every 'endpoint' or function we create. What if this: ```python def search_title(descr): results = [] conn = get_database('database.sqlite3.db') c = conn.cursor() parm = "%{}%".format(descr) SELECT_QUERY = " SELECT * FROM movies WHERE title like ? LIMIT 5 " result = c.execute(SELECT_QUERY, (parm,)) for movie in result: results.append(movie) conn.commit() conn.close() return results ``` Could become: ```python @db def search_title(descr, c=None): results = [] parm = "%{}%".format(descr) SELECT_QUERY = " SELECT * FROM movies WHERE title like ? LIMIT 5 " result = c.execute(SELECT_QUERY, (parm,)) for movie in result: results.append(movie) return results ``` That example doesn't remove much code, but, it removes the boilerplate stuff. We can use a 'decorator' to make this happen. --- # Decorator decorators wrap a function, modifying its behavior. Notice this: ```python def search_title(descr): ``` becomes ```python @db def search_title(descr, c=None): ``` 'db' is the decorator. We use the @ symbol to show that it's going to 'wrap' the function --- # Functions Things to know. Functions are 'first class objects'. We can pass a function around as a variable. e.g.: ```python def my_function(): pass f = my_function f() ``` That calls 'my_function' but with an 'alias' of `f`. --- # Back to decorators My goal with the `db` function is to be able to inject the database cursor for any method that needs it. That `abstracts` the details of the database away from that function. This helps with: * cleaner code * ability to test easier * hides changes to databases within one block of code. Let's look at the `db` decorator --- # @db ```python from functools import wraps . . . def db(func): @wraps(func) def wrapper_to_add(*args, **kwargs): cur = None conn = None try: conn = get_database('database.sqlite3.db') conn.row_factory = dict_factory cur = conn.cursor() a = func(*args, c=cur, **kwargs) logging.debug("Func returned a: ", a) conn.commit() return a except: logging.exception("Exception while processing. Will Attempt to Rollback") try: if conn: conn.rollback() except: logging.exception("Had an issue rolling back.") traceback.print_exc(file=sys.stdout) finally: if cur: cur.close() if conn: conn.close() return wrapper_to_add ``` --- # Why did we do that again? Imagine I want to: * change the database filename * Start using a Postgresql database * Use an in memory database for testing. * Use a different database in testing vs production ---

22 mg |

5-MeO-DMT |
(powder / crystals) |
My experience with 5-MeO-DMT marked the end of a long and exhausting year of drug experimentation. I should preface the actual report by saying that I was (in retrospect) deeply depressed at the time, and this undoubtedly colored my experience.
My friend (and then-roommate) and I got a 50mg bag of 5-MeO-DMT at a local store, and took it back to our apartment. I was the first to try it. I insufflate what we estimated was 15mg of the total amount, and sat down on the sofa. The onset was rapid and the experience was overpowering. I had previous experience with hallucinogens (LSD, psilocybin mushrooms, salvia) and had always felt able to differentiate and mediate between the experience and the 'I' as its subject: the hallucinations were consensual; I could open myself to them or hold back. This time, however, the experience was relentless and psychologically brutalizing, and I had barely enough sense to sit back and allow the drug to beat its path through my mind. The high tapered off rapidly after 10 or 15 minutes or so. After the high, I was nervous and giddy at the sheer unrelenting force of the drug. I felt no richer for the experience, merely beaten-up.
My friend was next. He took a smaller, 10mg dose, and was likewise immobilized and barely responsive on the couch for 10-15 minutes. He managed a few exclamations of awe. After we had both agreed the experience was like 'being shot out of a canon' and, though we didn't regret taking it, we wouldn't take it again.
My friend retired to his room to sleep, and the night would've ended there were it not for some still-inexplicable urge to go back and really brutalize myself. I insufflated most of the rest (~20-25mg) and went to lie down in my bed. Almost immediately my stomach felt most inauspicious, and I felt terror mount. I managed to get up and walk to the bathroom, where I gripped the sink hard with both hands and desperately wished the experience away.
Then it started. I was unprepared. I felt I had no recourse to any mental comfort and could not in any way make sense of what I was experiencing -- indeed, could not even recognize my own inability to make sense of my situation. The experience was beyond language. I can only say (in retrospect) that it felt the psychological analogue to plummeting very fast through a fractal void. 'I' was unadulterated terror.
When I came to, I was lying in the bathtub, my roommate standing over me looking very concerned. He was woken up by the sound of incoherent shouting, and found me in the bathtub flailing violently. I had vomited over myself and was bleeding from the nose. The whole thing lasted about 15-20 minutes. He was about to call for help. 'I'm OK,' I managed. 'I'm OK. I'm OK. I'm OK,' more for my sake then for his. I explained what I had done. When he was sufficiently convinced I was 'back', he retired again to his room. Something inside me had snapped, and I felt like an assemblage of broken parts.
I took drugs maybe once or twice after that, neither significantly hallucinogenic (cocaine and heroin -- both nasally and on different occasions.) Since then, almost any significantly psychoactive drug (incl. so-called 'mild' drugs like coffee and marijuana) causes me to feel distressed, even at small doses. As a result, I have avoided all but the rare alcoholic or caffeinated drink since. I suffer from frequent bouts of depression and anxiety. I don't know that I can link them to the 5-MeO-DMT experience, but I am certain it didn't help.

Nyzo version 519 (commit on GitHub) adds the full mesh as a fallback data source for the sentinel.
This version only affects the sentinel.
All changes in this version are in the Sentinel class. In addition to separate threads for each managed verifier, the sentinel now starts a single thread that, as a backup, can rely on the full mesh as a block source. Considerable work has been done on a unified blockchain-tracking mechanism that could be shared among the verifier, sentinel, and client, but using a unified mechanism requires some compromises. The sentinel's use of fully trusted verifiers during normal operation is efficient and stable, so it has been enhanced rather than replaced.
The full-mesh loop is simple, and it should be familiar to anyone who has reviewed the sentinel code. It is similar in structure to the loop in the managed-verifier threads. Like other sentinel loops, there is a timestamp to prevent the loop from iterating too quickly, and the loop begins by waiting for the message queue to clear. The actual block request is spaced out by at least the standard block-update interval (2 seconds), and it does not happen if the frozen edge was verified within the last 35 seconds. The block request occurs in a method called requestBlockWithVotes().
The requestBlockWithVotes() method is a simplification of the method with the same name in the Verifier class. The primary differences are use of the sentinel's combined mesh as a node source and bypassing of the BlockVoteManager class for tallying votes. Rather than wiring into the verifier's block-freezing mechanisms, this method is mostly self-contained.
The sentinel does not use NodeManager to track the state of the mesh. This prevents Message.fetchFromRandomNode() from working in the sentinel. The randomNode() method provides a random selection of a single node from a random managed verifier's list of nodes. The mesh changes slowly, so stale lists due to managed verifiers being offline are not concerning enough to warrant full-mesh querying of mesh information.
A check has also been added to exclude out-of-cycle verifiers from consideration when selecting a block for transmission. Sending a block for an out-of-cycle verifier will usually result in blacklisting of the sentinel's IP address, which would interfere with its ability to send blocks for other managed verifiers for a short time.

Spaceflower Swimsuit
In April, several of my coworkers and I decided to head to Budapest for CraftConf, which had a great speaker line-up. They offered diversity tickets, which made the trip actually affordable – tickets were almost 40% off for a 2-pack if you signed up with someone who identified as a different gender from you. Also, it’s really hard to say no to a trip to Budapest. The conference itself was really well-produced and organized, especially since it’s only in its second year.
So! I knew I’d be going to Budapest in about a month, and Budapest is famous for its thermal baths. Knowing that I’d be spending hours lounging around in pools, I did what any sane person would do. I made a bikini!
After making several (as-yet unblogged) versions of Cloth Habit’s Watson Bra, I knew this was the perfect pattern for a long-line bikini top. (I traced off a RTW bikini bottom for the other half of the pattern.) Though this was technically not a swimsuit pattern (it’s meant for lingerie), it didn’t take too much tweaking to make a lined swimsuit out of it.
Since I’ve made the pattern several times over, I was pretty confident with the fit and shape of it, and was fairly certain that it’d work well as swimwear. I sourced some swimsuit lycra and lining, and replaced some of the more finicky bra notiions with swimwear ones. I followed this swimalong for tips on how to convert patterns to be suitable for swimwear.
So, for pattern modifications:
1. Swimwear needs lining.
I cut a copy of every pattern piece out of nude swimwear lining, and managed to origami all the seams so there are no exposed seams anywhere. This took a lot of 2 am head-scratching, and fancy folding and twisting – I’m really happy with the end result. I also slipped in molded foam cups using this tutorial.
I didn’t want the top-stitching to overwhelm the pattern and colors, so I used invisible thread. This stuff looks exactly like fishing line, and is a little scratchy. Not sure this was the best decision, but it looks great!
2. Stabilizing
I didn’t want to use powermesh for the back band, and also needed some way to stabilize the cradle to keep it from distorting. I used a double layer of the lycra to ~stabilize both the cradle and the back band, which worked great! The lycra I’m using is very firm, and doesn’t have that much stretch when doubled.
3. Straps, elastic, and notions.
The elastic, especially, is crucial to replace – normal, non-braided lingerie elastic has a tendency to stretch out in water, which is bad news bears. I bought braided elastic, and turned all the elastic to the inside, for a nice clean finish. (This is similar to attaching lingerie elastic, but I attached the elastic to the inside, then folded it over again to topstitch.) The straps are normal bra elastic covered in the swimsuit lycra, using this tutorial for making long, skinny spaghetti straps. I was a little worried about the straps stretching out in water, but they seem to hold up great.
Dealing with the long-line back was kind of a pain. I initially scooped out the strap to fit my 1” clear swimsuit hook, but it looked really unbalanced to have a 3” back band swoop down to 1” over my back. To fix this, I ended up adding a second band and hook at the top of the back band. I’m really happy with the look of this, especially since it kind of echoes the doubled-up straps above it. It also provides so much more support!
A note – the dressform I’m using to model the swimsuit is a friend’s, so it’s a different size/shape than I am. Luckily, most of the swimsuit is stretchy enough that it ~mostly fits on the dressform.
I’ve worn this swimsuit several times now, and it’s held up to sulfurous thermal baths and the wild waves of the Pacific. It fits like a glove, and I’m really happy with the absurd print!
Fabric // Meadow galaxy swimsuit lycra from Fabric Fairy, and nude swimsuit lining and elastics also from Fabric Fairy.
Pattern // Cloth Habit’s Watson Bra
Sizing/Adjustments // 30G bra + traced RTW bikini bottom. Adjusted for swimwear.

a values vector, or matrix of values ensemble members (ensembles in columns) |
| changeFun |
the change function to across which to propagate |
| n.ens |
How many ensembles to use for error propagation? (default = 100) |
| mc.ens |
How many Monte Carlo simulations to use for null hypothesis testing |
| surrogate.method |
What method to use to generage surrogate data for hypothesis testing? Options include:
'isospectral': (Default) Following Ebisuzaki (1997), generate surrogates by scrambling the phases of the data while preserving their power spectrum. This uses the To generate these “isospectral” surrogates. Uses the rEDM::make_surrogate_data() function
'isopersistent': Generates surrogates by simulating from an autoregressive process of order 1 (AR(1)), which has been fit to the data. Uses the geoChronR::createSyntheticTimeseries() function
'shuffle': Randomly shuffles the data to create surrogates. Uses the rEDM::make_surrogate_data() function

Arguments passed on to propagateUncertainty
simulate.time.uncertainty TRUE or FALSE. If an ensemble is not included, do you want to simulate time ensembles (default = TRUE)
simulate.paleo.uncertainty TRUE or FALSE. If an ensemble is not included, do you want to simulate paleo ensembles (default = TRUE)
bam.model BAM Model parameters to use if simulating time uncertainty (default = list(ns = n.ens, name = "bernoulli", param = 0.05), paleo.uncertainty = sd(vals,na.rm = TRUE)))

{% extends "global/Base.html" %} {% load otree %} {% block title %}Thank you for participating in the Canteen Dilemma{% endblock %} {% block content %}
The Canteen Dilemma intends to show what happens when people try to coordinate their actions without common knowledge. 'Common knowledge', as defined in the research literature, is much more than simply saying that something is known by all. It also implies that the fact that it is known is also known by all, a sort of agreement to the infinite degree.
Even if your colleague knows your arrival time (+/- 5 minutes), it still is unclear what you know she knows about what you know about what she knows about your arrival time. She might arrive at 8:40 and know that you cannot arrive any later than 8:45. But if this is the case, you might think she arrived at 8:50, making her think that you arrived at 8:55, making you think that she arrived at 9:00. Bam!
Thus, Common Knowledge - in its ultimate sense - implies not only that people know some piece of information, but also that you can be absolutely confident that everybody knows that everybody know it, and so on. The canteen dilemma shows that without Common Knowledge you must eventually conclude that you never can meet in the canteen! At least if you do not want to risk losing any hard earned bonuses.


Emergencies in the UK.
Making a plan and being prepared are key to resilience. Here's some tips on how to prepare, what to do if disaster strikes and how to get back to normal as soon as possible afterwards.
Motorway breakdown.
-
Service your car.
Prevention is much better than waiting for a breakdown. Ensure your car is serviced regularly
-
Don't stop.
Only stop if its a real emergency. Try to drive to a safer place off the motorway rather than stopping on the hard shoulder
-
On the hard shoulder.
If you must stop pull over as far left as possible. Leave sidelights on and switch on hazard flashers.
-
Don't stand on the hard shoulder.
Fast moving traffic won't see you. Keep passengers and yourself away from the carriageway and hard shoulder behind the barrier or up the bank. Don't attempt even simple repeairs
-
Give an accurate location.
Walk to your nearest emergency telephone, or describe your location using reference numbers on all telephone marker posts
-
Build up speed before pulling onto carriageway.
Before rejoining, build up speed on the hard shoulder and watch for a safe gap in the traffic Be aware that other vehicles may be stationary on the hard shoulder
Chemical Emergencies.
-
Keep chemicals safe.
Keep medicines and cleaning products out of site and reach of children.
-
Keep in original containers.
Never decant into soft drink bottles, someone might accidentally drink them.
-
Next mix products.
Some combinations can create toxic gases.
-
Don't leave spills.
Clean up spills immediately with rags. Be careful to protect your eyes and skin.
-
Call emergency services.
Call on 999
-
Seek expert advice.
Don't give anything by mouth. Unless advised by medical profesional
-
Move away from the chemicals.
Move away from immediate source of chemical danger.
-
Know what you are dealing with.
Keep the label of the chemical with you to show to emergency services.
-
After a spill.
If dangerous chemical released into environment listen to the news and follow instructions
-
Wait inside.
If told to wait inside put tape around closed doors, windows and air vents.
Flu.
Influenza causes many deaths annually and can infect millions of people in pandemic.
-
Coughs and sneezes.
 Bin after use.
-
Wash your hands.
Regularly wash your hands with soap and hot water or a sanitiser gel.
-
Clean hard surfaces.
Keep door handles, remote controls and computer mice clean.
-
Stay at home.
During a pandemic you will be advised to stay indoors. If in doubt call your GP or the NHS on 111.
-
Stay healthy.

Terrorist attack.
Terror attacks can happen without warning but you can prepare for peace of mind.
-
Be vigilant.
Attacks would normally happen in public places. Keep an eye out for suspicious behaviour, vehicles or packages. Call the police anti-terror hotline on 0800 789 321 if you have doubts.
-
Know your exit.
In buildings and transport be aware of the emergency exits.
-
Get out.
Look for the safest way out of a building or away from the vicinity. Leave as quickly and calmly as possible.
-
If inside and there falling items.
Shelter under a sturdy table. If trapped, stay close to the wall. Don't use lighters or matches as there may be gas leaks.
-
Alert the police.
If you saw the explosion or any suspicious behaviour, tell the police what you saw.
-
Help others.
In the immeidate aftermath, help others if you can give first aid and support.
