| A Cup of Radicchio: Upgrade OpenBSD 6.3 to 6.5 A personal website of a power looper, a skateboarder, and a coder |
|
| Home Docs Sources Blog GitHub |
20th of June, 2019
As clearly stated in the OpenBSD FAQ regarding upgrading one release to another, upgrades are only supported from one release to the release immediately following it. So what to do if it needs to upgrade the 6.3 release of OpenBSD to the 6.5 release, is to upgrade sequentially, first to the 6.4 release, and then to the 6.5 release.
Upgrade OpenBSD 6.3 release to 6.4 release
(a) Having installed and running the OpenBSD/amd64 6.3 release, first of all it needs to download the new (6.4) ramdisk kernel bsd.rd
and the checksum file SHA256.sig
for the appropriate architecture, in this case amd64
:
$ curl -sO https://cdn.openbsd.org/pub/OpenBSD/6.4/amd64/bsd.rd \
-sO https://cdn.openbsd.org/pub/OpenBSD/6.4/amd64/SHA256.sig
(b) Verify checksum of the new ramdisk kernel:
$ signify -C -p /etc/signify/openbsd-64-base.pub -x SHA256.sig bsd.rd
Signature Verified
bsd.rd: OK
(c) Permanently set the new CDN URL (it was changed in the 6.4 release) which will be using during system upgrade and later on during upgrading packages:
$ cat /etc/installurl
https://ftp.openbsd.org/pub/OpenBSD <== The old one.
$
$ sudo su -
# echo "https://cdn.openbsd.org/pub/OpenBSD" > /etc/installurl
$
$ cat /etc/installurl
https://cdn.openbsd.org/pub/OpenBSD <== The new one.
(d) Remove unneeded (unused) files:
$ sudo rm -vf /dev/audio /dev/audioctl
/dev/audio
/dev/audioctl
$
$ sudo rm -vf /etc/rc.d/rtadvd /usr/sbin/rtadvd \
/usr/share/man/man5/rtadvd.conf.5 \
/usr/share/man/man8/rtadvd.8
/etc/rc.d/rtadvd
/usr/sbin/rtadvd
/usr/share/man/man5/rtadvd.conf.5
/usr/share/man/man8/rtadvd.8
$
$ sudo rm -vf /usr/X11R6/lib/libxcb-xevie.* \
/usr/X11R6/lib/libxcb-xprint.* \
/usr/X11R6/lib/pkgconfig/xcb-xevie.pc \
/usr/X11R6/lib/pkgconfig/xcb-xprint.pc
/usr/X11R6/lib/libxcb-xevie.a
/usr/X11R6/lib/libxcb-xevie.so.1.0
/usr/X11R6/lib/libxcb-xprint.a
/usr/X11R6/lib/libxcb-xprint.so.3.0
/usr/X11R6/lib/pkgconfig/xcb-xevie.pc
/usr/X11R6/lib/pkgconfig/xcb-xprint.pc
(e) Remove unneeded (unused) user and group:
$ sudo userdel _rtadvd && sudo groupdel _rtadvd
(f) Disable starting up the buildslave
(obsolete) daemon:
$ sudo rcctl disable buildslave
(g) Copy the new ramdisk kernel to the root filesystem:
$ sudo cp -vf bsd.rd /
bsd.rd -> /bsd.rd
== IT'S THE TIME TO BOOT INTO THE NEW KERNEL ==
(h) Reboot:
$ sudo shutdown -r now
(i) At the boot loader prompt type bsd.rd
and hit <Enter>
:
boot> bsd.rd
(j) After the kernel is booted, hit s
(that means (S)hell
) to enter the shell to configure network if not already autoconfigured. In the shell make necessary network configurations, then hit <Ctrl-D>
to return to the installation/upgrading program. (This step is very important if, for example, OpenBSD is installed and running inside a virtual machine, like this one):
# ifconfig vio0 <IP_ADDRESS>/24
# route add default <IP_ADDRESS>
add net default: gateway <IP_ADDRESS>
# ^D
(k) Hit u
(that means (U)pgrade
) and follow sequential prompts. In most cases for most questions just hit <Enter>
for default choices.

OpenBSD 6.5 (GENERIC.MP) #3: Sat Apr 13 14:48:43 MDT 2019
Welcome to OpenBSD: The proactively secure Unix-like operating system.

version of the code. With bug reports, please try to ensure that

...and making initial network configurations...
$ sudo ifconfig vio0 <IP_ADDRESS>/24
$ sudo route add default <IP_ADDRESS>
add net default: gateway <IP_ADDRESS>
...it's the time to upgrade packages: $ sudo pkg_add -uv
; but first check the package database:
$ pkg_info
perl:/usr/local/libdata/perl5/site_perl/amd64-openbsd/auto/Cwd/Cwd.so: undefined symbol 'PL_sv_undef'
Can't load '/usr/local/libdata/perl5/site_perl/amd64-openbsd/auto/Cwd/Cwd.so' for module Cwd: Cannot load specified object at /usr/local/libdata/perl5/site_perl/amd64-openbsd/XSLoader.pm line 96.

Compilation failed in require at /usr/libdata/perl5/OpenBSD/PackageInfo.pm line 168.
The command above doesn't work, and as it is clearly seeing in the output, something gets wrong with the Perl module Cwd
. But further investigations show out that this module (as being an XS-module) was compiled to use with the previous version of Perl, hence it is incompatible with the currently installed Perl release.
Obviously, the easiest solution to repair this crucial Perl module is to replace the whole Perl base module set with that one freshly downloaded from the OpenBSD CDN. It is contained in the base65.tgz
tarball. The following compound one-liner command will replace the old Perl base module set with the new one, with minimal effort from the user side:
$ mkdir xyz && \
cd xyz/ && \
curl -sO https://cdn.openbsd.org/pub/OpenBSD/6.5/amd64/base65.tgz && \
tar -xzf base65.tgz && \
sudo rm -Rf /usr/local/libdata/perl5/site_perl/amd64-openbsd/* && \
sudo cp -Rf ./usr/libdata/perl5/amd64-openbsd/* /usr/local/libdata/perl5/site_perl/amd64-openbsd/ && \
cd - && \
sudo rm -Rf xyz/
Now package manipulation commands (pkg_info
, pkg_add
, pkg_delete
, etc.) should be working fine:
$ pkg_info

Sinatra is a very very simple Webframework for Ruby. A friend of mine ask me how hard is it to make a web application which reads and writes from a database. Here I will show you how simple it is. This code will not be scalable nor be best practise or something but it will be as simple as possible. You will see you can learn the basics on one day easy.
To do this tutorial install ruby and and install the Sinatra framework. This can easily doe with:
sudo apt-get install ruby
gem install sinatra
easy right?
So here are the standard "Hello World".
require "sinatra"
get "/" do
"Hello World"
end
Save this as a hello_world.rb and type
ruby hello_world.rb
Thats it its THAT simple! Just go to "http://localhost:4567" and you will see your "Hello World". "Ok that was easy but I want more!"
You probably don't want everything in this file (remembers me of old PHP times :) )
So make a folder called "views". There you put a file called "helloworld.erb". In this "helloworld.erb" we write:

<title>Hello World</title>

Hello World

the Sinatra part we change to:
reuqire "sinatra"
get "/" do
erb :hello_world
end
Not go to your console and close the old server with "Strg+C". Then type again
ruby hello_world.rb
then you should see Your "Hello World" again. Now play a bit with the html to see how it changes. Till now we only had normal html in the ".erb" file. But erb can more! We will now use a variable from Sinatra and will render them in the erb file.
so change the "hello_world.rb" to these
require "sinatra"
get "/" do
@foo = "This is some text."
erb :hello_world
end
and change the "hello_world.erb" to this

<title>Hello World</title>

<%= :foo%>

Hello World

Wow this allows us to do much more! Well now it's time to look how we can receive data from the user/browser. For this we need a formula so please change your ".erb" file to this:

<title>Hello World</title>

<%= :foo%>

Hello World

<form action="action_page">
First name:

<input type="text" name="firstname">

Last name:

<input type="text" name="lastname">
<button type="submit">Send</button>
</form>

Do you see the field name="lastname" ? This do we need later to identify which data from the browser we want to read. More information about form fields in html you find here.
Now to the server part change it to this:
require "sinatra"
get "/" do
@foo = "This is some text."
erb :hello_world
end
get "/action_page" do
foo = params[:firstname]
foo = "Hello " + foo + " " + params[:lastname]
foo
end
and when we execute it and you fill out the form you will see a text like this:
"Hello Peter Pan"
OK thats pretty cool now we can receive data to the user and send data to the user. But what if we want to save something? For this normally a database is used. So as the last part I will show you how to read and write from the database.
So to communicate with the database we need a database driver and of course we need to install the database we do this with:
sudo apt-get install mysql-server
gem install gem install mysql2
now we have everything installed but we need to create the database and then create a table (btw. a pretty good tutorial for this is here and here ) so
mysql -u root -p
CREATE DATABASE database foobar;
use foobar
CREATE TABLE users (id INT NOT NULL PRIMARY KEY AUTO_INCREMENT,
name VARCHAR(20),
food VARCHAR(30),
confirmed CHAR(1),
signup_date DATE);
INSERT INTO `users` (`id`,`name`,`food`,`confirmed`,`signup_date`) VALUES (NULL, "John", "Casserole","Y", '2012-04-11');
then we change the server to this
require "sinatra"
require "mysql2"
get "/" do
client = Mysql2::Client.new(:host => "localhost", :username => "root")
@results = client.query("SELECT * FROM users")
@foo = "This is some text.\n" + @results.to_s
erb :hello_world
end
get "/action_page" do
client = Mysql2::Client.new(:host => "localhost", :username => "root")
client.query('INSERT INTO `users` (`id`,`name`,`food`,`confirmed`,`signup_date`) VALUES (NULL, ' + params[:firstname] + ', "' + params[:lastname] + '","Y", '2012-04-11')')
foo = params[:firstname]
foo = "Hello " + foo + " " + params[:lastname]
foo
end
Now here I should warn you not to program like these in the wild web as its insecure as hell but for our litte course this ok. So now you see how you can insert and read from a database. And here we at the end. You have learned the basics now play a bit and read more tutorials. May you identify where I did bad practise. If so try to correct it. Try to make it more beautiful with CSS (Sinatra will expect that the CSS is in a folder called public.) digg into it it's fun!


Beyoncé said motherhood and age has made her feel ‘more womanly and secure’ with her curves
by Julia Naftulin- In a new interview in Elle magazine, Beyoncé Knowles-Carter discussed her body evolution and how motherhood and getting older helped her come to terms with her changing body.
- “If someone told me 15 years ago that my body would go through so many changes and fluctuations, and that I would feel more womanly and secure with my curves, I would not have believed them,” the “Formation” singer said.
- Knowles-Carter also said she recently learned how to find self-worth beyond her physical appearance and discussed how rewarding that experience has been.

It may be hard to believe, but even superstar Beyoncé isn’t always secure in her appearance.
In a new interview in Elle magazine, Knowles-Carter discussed her body evolution and how motherhood and getting older has helped her come to terms with her changing body.
After going through a difficult pregnancy with her twins Rumi and Sir, Knowles-Carter said she used 2019 as a year to focus on self-care and her own health. To do this, she said she focuses on a healthy diet and does acupuncture, meditation, and breathing exercises.
It paid off.
“If someone told me 15 years ago that my body would go through so many changes and fluctuations, and that I would feel more womanly and secure with my curves, I would not have believed them,” the “Formation” singer said.
Knowles-Carter also said she recently learned how to find self-worth beyond her physical appearance and discussed how rewarding that experience has been.
She said she now knows she’s “more than enough no matter what stage I’m at in life. Giving zero f—-s is the most liberating place to be.”
This isn’t the first time Beyoncé has opened up about her difficult pregnancy
The Netflix documentary “Homecoming” that details Knowles-Carter’s 2018 Coachella performance also offered a look into the the complications the songstress faced because she had toxemia (also known as preeclampsia), a pregnancy complication characterized by high blood pressure, weight gain, and protein in the urine.
Beyoncé also detailed her complicated pregnancy in a personal essay in the September 2018 issue of Vogue.
In the essay, the mom of three wrote she was “swollen from toxemia and had been on bed rest for over a month” during the time. Ultimately, the condition caused her to have an emergency C-section to deliver the twins. Following the birth, she and the twins spent weeks in the neonatal intensive care unit.

Fast Company (1979) 91m.
While FAST COMPANY appears to be an unremarkable racing picture to the casual viewer, it's of some interest to film buffs because it is a most unusual entry in the oeuvre of horror director David Cronenberg. If you were unaware of his filmography, you'd probably think that this was his debut feature - it certainly has that New World Pictures look about it, as if Cronenberg was part of the stable of up-and-coming film-makers recruited by Roger Corman during the 70s. Its B-movie elements are also supplemented by a soundtrack of original rock tunes (which sound like a mixture of Bob Seger and Bruce Springsteen) and co-starring roles from exploitation regulars John Saxon and Claudia Jennings.
 It's this blink-and-you'll-miss-it factor that influences the documentary look of the racetrack scenes.  They run not on gas, but a mixture of nitro and alcohol, and their edgy jockeying for position gives us the feeling of an imminent explosion - which their sudden, furious bursts of speed become. Throughout, we're waiting for the crash that must be coming. Racetracks generally make good metaphors for the film characters that inhabit them, but there's no endless looping around a static circuit in FAST COMPANY. The short bursts of speed - their preparation, buildup and release - would fasten themselves easily enough to repressed, inarticulate characters, but paradoxically the drivers in FAST COMPANY are likeable and easy-going. As the protagonist Lonnie 'Lucky Man' Johnson, William Smith doesn't display any passion for racing.  This is America, as evidenced by the constant red-white-blue coloring of the film, and car culture is the thing that it's built on. Cronenberg, who took on the project because of his interest in motor racing, doesn't attempt any of the body/machine collisions he is famous for in his work, but is settles for a more purely psychological approach: that in a motorized, mechanized age, those who make their livings around machines become consumed by them.
There's little to distinguish FAST COMPANY from other speedway films, B-movie or otherwise, but it's still agreeable viewing and has a few interesting moments. Somewhat uncharacteristically, Jennings is the only female member of the cast to keep her clothes on. This would turn out to be her last film - ironically she would die behind the wheel in a car crash soon afterwards. Cronenberg, of course, would go on to direct CRASH several years later, the seeds perhaps already having been sown by this earlier project. As it turned out, FAST COMPANY became a victim of legal problems and the film's cinema release lasted about as long its drag races.

EDNS options¶
This example shows how to interact with EDNS options.
When querying unbound with the EDNS option 65001
and data 0xc001
we
expect an answer with the same EDNS option code and data 0xdeadbeef
.
Key parts¶
This example relies on the following functionalities:
Registering EDNS options¶
By registering EDNS options we can tune unbound’s behavior when encountering a query with a known EDNS option. The two available options are:
bypass_cache_stage
: If set toTrue
unbound will not try to answer from cache. Instead execution is passed to the modulesno_aggregation
: If set toTrue
unbound will consider this query unique and will not aggregate it with similar queries
Both values default to False
.
if not register_edns_option(env, 65001, bypass_cache_stage=True,
no_aggregation=True):
log_info("python: Could not register EDNS option {}".format(65001))
EDNS option lists¶
EDNS option lists can be found in the module_qstate
class. There are
four available lists in total:
module_qstate.edns_opts_front_in
: options that came from the client side. Should not be changedmodule_qstate.edns_opts_back_out
: options that will be sent to the server side. Can be populated by edns literate modulesmodule_qstate.edns_opts_back_in
: options that came from the server side. Should not be changedmodule_qstate.edns_opts_front_out
: options that will be sent to the client side. Can be populated by edns literate modules
Each list element has the following members:

: the EDNS option code;data
: the EDNS option data.
Reading an EDNS option list¶
The lists’ contents can be accessed in python by their _iter
counterpart as
an iterator:
if not edns_opt_list_is_empty(qstate.edns_opts_front_in):
for o in qstate.edns_opts_front_in_iter:
log_info("python: Code: {}, Data: '{}'".format(o.code,
"".join('{:02x}'.format(x) for x in o.data)))
Writing to an EDNS option list¶
By appending to an EDNS option list we can add new EDNS options. The new
element is going to be allocated in module_qstate.region
. The data
must be represented with a python bytearray
:
b = bytearray.fromhex("deadbeef")
if not edns_opt_list_append(qstate.edns_opts_front_out,
o.code, b, qstate.region):
log_info("python: Could not append EDNS option {}".format(o.code))
We can also remove an EDNS option code from an EDNS option list.
if not edns_opt_list_remove(edns_opt_list, code):
log_info("python: Option code {} was not found in the "
"list.".format(code))
Note
All occurences of the EDNS option code will be removed from the list:
Controlling other modules’ cache behavior¶
During the modules’ operation, some modules may interact with the cache
(e.g., iterator). This behavior can be controlled by using the following
module_qstate
flags:
module_qstate.no_cache_lookup
: Modules operating after this module will not lookup the cache for an answermodule_qstate.no_cache_store
: Modules operating after this module will not store the response in the cache
Both values default to 0
.
def operate(id, event, qstate, qdata):
if (event == MODULE_EVENT_NEW) or (event == MODULE_EVENT_PASS):
# Detect if edns option code 56001 is present from the client side. If
# so turn on the flags for cache management.
if not edns_opt_list_is_empty(qstate.edns_opts_front_in):
log_info("python: searching for edns option code 65001 during NEW "
"or PASS event ")
for o in qstate.edns_opts_front_in_iter:
if o.code == 65001:
log_info("python: found edns option code 65001")
# Instruct other modules to not lookup for an
# answer in the cache.
qstate.no_cache_lookup = 1
log_info("python: enabled no_cache_lookup")
# Instruct other modules to not store the answer in
# the cache.
qstate.no_cache_store = 1
log_info("python: enabled no_cache_store")
Testing¶
Run the Unbound server:
root@localhost$ unbound -dv -c ./test-edns.conf
In case you use your own configuration file, don’t forget to enable the Python module:
module-config: "validator python iterator"
and use a valid script path:
python-script: "./examples/edns.py"

#Try:
# - dig @localhost nlnetlabs.nl +ednsopt=65001:c001
# This query will always reach the modules stage as EDNS option 65001 is
# registered to bypass the cache response stage. It will also be handled
# as a unique query because of the no_aggregation flag. This means that
# it will not be aggregated with other queries for the same qinfo.
# For demonstration purposes when option 65001 with hexdata 'c001' is
# sent from the client side this module will reply with the same code and
# data 'deadbeef'.

Health Connect is intended for all kinds of innovation any stage of development - from idea, to prototype, to after UK market launch.
Products and services that that are likely to offer substantial measurable benefits to patients (or other service users) or the UK health and care system compared to the current UK standard of care will get the most benefit from using Health Connect. For example:
Products and services that are likely to offer similar benefits to to patients or the UK health and care system when compared to current UK practice are unlikely to benefit the most from using Health Connect. For example:
A limited number of people working on behalf of an approved Accessor organisation can access Health Connect.
Doctors, nurses, and other healthcare professionals will not have access to Health Connect unless they also have a role in one of the approved Accessor Organisations and are registered to use the system as a Data Accessor on behalf of the Accessor Organisation.

mig - message interface generator for nesC
mig [any ncc option] [-o output-file] [-java-classname=full-class-name] [-java-extends=class-name] tool msg-format-file message-type
mig is a tool to generate code that processes TinyOS messages. The tool argument specifies what tool should be generated, the msg-format-file specifies your application's top-level nesC file, and the message-type specifies the C type of the message you wish to process. The C type must be defined with `struct message-type' or `union message-type' in a .h file which your nesC application `includes'. If your .h file defining the message type does not depend on any other files, then you can specify the .h file directly as the msg-format-file.If you also need access to some constants from your nesC application, please consult the ncg man page.
If an enum constant named AM_message_type (with message_type capitalized) is found, then the value of that constant is assumed to be the active message type for message-type.
Currently there is only one tool, java, which generates a java class that encodes and decodes messages. The -java-* options are specific to this tool. It is described below.
-o output-file
specify the file in which to output the generated code.mig works by invoking ncc. It will generally be necessary to pass some options through to ncc so that your file can be compiled. Some commonly necessary options are:-target=known-tinyos-platform
specify the target architecture of your TinyOS application which is generating or receiving messages. So, e.g., if compiling your application for tossim specify -target=pc. The default target is ncc's default target.-I dirspecify an additional search directory for nesC components.-board=known-tinyos-sensorboardspecify one (or more) sensor boards. This effects the search path and preprocessor symbols (and may therefore be necessary when feeding a file to mig).
This tool generates a java class to encode or decode a TinyOS packet, basing itself on the net.tinyos.message infrastructure. For each field fname of structure message-type, there are the following methods (the bit offset and size methods are useful for structures containing bitfields):
Embedded structures in message-type are expanded, using _ to separate the structure name and its fields.
get_
fname: get field's valueset_
fname: set field's valueoffsetBits_
fname: return bit offset of field in message-typeoffset_
fname: return byte offset of field in message-typesizeBits_
fname: return size in bits of field (not for arrays)size_
fname: return size in bytes of field (not for arrays) (absent if fname is a bitfield)isSigned_
fname: return true if fname is of a signed typeisArray_
fname: return true if fname is an arrayA number of extra methods are present for fields that are arrays:
If the array is 1-dimensional and the elements are one byte, then the following methods exist:
getElement_
fname: get an element of the arraysetElement_
fname: set an element of the arrayelementSize_
fname: return size in bytes of array elementselementSizeBits_
fname: return size in bits of array elementsnumDimensions_
fname: return number of dimensions of the arraynumElements_
fname: return number of elements of the array for a given dimension (left-most dimension is numbered 0) - the dimension is optional for 1-dimensional arraystotalSize_
fname: return size in bytes of the array (absent if the array is variable-size)totalSizeBits_
fname: return size in bits of the array (absent if the array is variable-size)getString_
fname: build a Java string from the array assuming it contains a C-style null-terminated stringsetString_
fname: set the array to a C-style null-terminated string given a java stringThe
getElement_..., setElement_...,offset_...
andoffsetBits_...
methods take one argument per array dimension. These methods report errors if the array index is out of bounds. If an array has a maximum size of 0, mig assumes it represents a variable-size array and does not check the corresponding array index. The data for a message is stored in an array, with explicit base and length information. The constructors can either allocate this array, receive it as an explicit argument or extract if from another message. The base and length can also be optionally passed to these constructors.The optional length argument overrides the default size of sizeof(message-type); this is useful for variable-size messages. The use of an explicit base is helpful for messages embedded in other messages.
The generated class also has an amType() method which returns the message's active message type, or -1 if no AM_message_type constant was found.
The java tool accepts the following options:
-java-classname=full-class-name
this option is required and specifies the package and name of the generated class. If the full-class-name has no '.', then no package directive is included in the output.-java-extends=class-name:specify the class the generated class will extend. The default is net.tinyos.message.Message.
APPDIR=`ncc -print-tosdir`/../apps/Ident
mig java -I $APPDIR -java-classname=net.tinyos.ident.IdentMsg $APPDIR/App.nc IdentMsg -o IdentMsg.java
mig reports an error if ncc cannot compile msg-format-file, if message-type isn't found or if it contains pointers.

Project 3: Digital Storytelling
The purpose of this project was to design, develop, and publish a digital narrative. For this assignment I worked with fellow designer Jonathan Flores to make a choose your own murder mystery adventure game. The original idea for the game was inspired by the movie Hush and the board game Clue. In the game you can follow the path of the female murder while trying to hunt down the victim in their own house or take your chances with running from a murder in the middle of the woods. The game is made up of twenty-two interconnected webpages coded by Jonathan Flores and illustrated by myself.

Important Concepts
About the web
A web browser allows a user to make request to servers using HTTP protocol. Servers respond to the requests with the selected HTML files that the browser displays. The web is a collection of HTML documents.
HTML
Hypertext Markup Language (HTML) is the basis of any webpage. The text is what is displayed on a webpage and the markup is what the content looks like or how it is arranged. HTML also has references to other documents such as images or videos.HTML Markup
Elements are composed of opening and closing tags.All whitespace (tabs, paragraphs, spaces) in HTML turn into a single space when displayed on a webpage.
Inline elements- just text
An example of an inline element is a break (br) tag that is used to create a line break (it is a voidtag).
Block elements–makes invisible boxes around content
An example of a block element is a paragraph (p) tag, it is not a void tag, and it can also be used to create a break.

2019 Holden Colorado review: V8 Harrop Superado
by Sam PurcellUnfortunately, the legendary and ubiquitous Aussie V8 ute has been assigned to the history books for some time now.
Those wanting one will be trawling through second-handers instead of showroom floors, as the market has pivoted towards the 4X4 ute.
One option is a tuned Holden Colorado by engineering outfit Harrop, who call their car the 'Superado'.
Sam Purcell finds out what it is like to drive.

El Salvador expels Venezuelan diplomats
San Salvador reiterates recognition of opposition leader Juan Guaido as Venezuela's interim president.
El Salvador's government has announced the expulsion of Venezuela's diplomatic corps and given them 48 hours to leave the country.
In a statement shared by President Nayib Bukele on Twitter on Sunday, the government explained the decision aimed to be coherent with previous declarations of Bukele where he has "repeatedly" not recognised the legitimacy of Venezuela's President Nicolas Maduro.
More:
The statement said the Salvadoran government recognised opposition leader Juan Guaido as Venezuela's interim president "until free elections are held".
El Salvador would receive new diplomatic representatives named by Guaido, the government added.
"In the near future, El Salvador awaits the receipt of credentials for Venezuela's new diplomatic representation", the statement said.
A number of countries, including the United States, Brazil, Colombia and Chile, recognised Guaido as Venezuela's leader after he declared himself interim president in January, saying that Maduro's re-election was illegitimate.
The US ambassador to El Salvador, Ronald Johnson, quickly backed the move.
"We applaud the government of Nayib Bukele for ensuring that El Salvador is on the right side of history by recognising Guaido as the interim president of Venezuela," he said on Sunday.
"The Venezuelan people have the right to elect a president and a government that works for the welfare of their people, instead of serving personal interests."
The decision came days after the US government extended temporary protection for Salvadoran people living in the country by an additional year.
The Temporary Protected Status (TPS) was provided to citizens of the Central American country following two devastating earthquakes in 2001 that killed 8,000 people and left hundreds of thousands homeless.

ONE NIGHT STAND RATING: 5 / 10 --> Not good
Review Date: May 3, 1998 Director: Mike Figgis Writer: Mike Figgis Producers: Mike Figgis and Ben Myron Actors: Wesley Snipes as Max Carlyle Nastassja Kinski as Karen Ming-Na Wen as Mimi Kyle MacLachlan as Vernon Robert Downey Jr. as Charlie Genre: Drama Year of Release: 1997
Mike Figgis' follow-up to the critically acclaimed LEAVING LAS VEGAS (8.5/10) from 1995, examines the repercussions of marital infidelity, and another man's struggle with HIV contamination.
PLOT: A married man with two kids has a one-night affair with a married woman during a weekend business trip to New York. Once back in LA, he contemplates his life and the consequences of his sinful act.
CRITIQUE: Comparing this film to FATAL ATTRACTION (8/10) or PHILADELPHIA (7/10) would be doing a great disservice to either one of those films, but nonetheless, the plot line doesn't stretch far from their respective story lines. Marital infidelity and a close friend dying of AIDS are the main topics in this film. Unfortunately, Figgis resolves absolutely nothing in regards to the infidelity topic, and scores only a few points in respect to the horror of a man dying of this disease. The film concludes on an absolutely ridiculous circumstance, which doesn't actually show anyone working through any of their complex issues.
The main problem I had with this film was its lack of honesty and realism in regards to the after-effects of a one-night affair. Nobody in this story seemed hurt, angry or despondent about the situation, while the better half of the film concentrated on a friend's struggle with the fatal disease. Robert Downey Jr. played his part as the man dying of AIDS remarkably well, while the rest of the cast didn't offer any mentionable performances. I found Kinski's character weak in persona, but did like Ming-Wa's strong and independent wife character (Mind you, I've had a thing for her since TV's "The Single Guy").
Overall, this film had very little entertainment value, no grand moral conclusions or solutions, and nothing exceptionally interesting to offer anyone. Figgis' directorial style was cool at times, but he did overuse the "fade to black" shot during one too many internals. If you are interested in either subject matter of this movie, I suggest that you rent either one of the two films that I mentioned earlier on, and save yourself some time and money.
Little Known Facts: Joe Eszterhas was an uncredited writer on this film (This might explain a lot of things...:)). Wesley Snipes appeared in Michael Jackson's "Bad" music video. You can only see him in the full length, 16 minute, black & white/color music video. And despite the fact that Wesley does not often acknowledge it, he did attend the State University of New York (SUNY) at Purchase and graduated with a BFA in 1985. Robert Downey Jr. lived with fellow actor Sarah Jessica Parker for 7 years during the 1980s, and studied ballet in London when he was young. Nastassja Kinski has a daughter with Quincy Jones, and is fluent in English, German, French, Italian and Russian.

Later I learned from Ghak, who had finally come to his tribesmen and returned with a party to rescue me, that the ryth, as it is called, pursued the Sagoths until it had exterminated the entire band. Ghak was, of course, positive that I had fallen prey to the terrible creature, which, within Pellucidar, is truly the king of beasts.
Tab Two
Just at this moment Alice felt a very curious sensation, which puzzled her a good deal until she made out what it was: she was beginning to grow larger again, and she thought at first she would get up and leave the court; but on second thoughts she decided to remain where she was as long as there was room for her.
Tab Three
"I was a young man when the Plague came—twenty-seven years old; and I lived on the other side of San Francisco Bay, in Berkeley. You remember those great stone houses, Edwin, when we came down the hills from Contra Costa? That was where I lived, in those stone houses. I was a professor of English literature."


Destiny 2 Season of Dawn starts on 10 December
by Steve WrightYou've still got time to mop up Season of the Undying, Guardians.
Destiny 2 Season of Dawn will commence on 10 December, developer Bungie has revealed.
Not much else is known of Destiny 2‘s next season, though generally we know it will bring a new seasonal artifacts alongside new Triumphs, rewards and various challenges.
The change in seasons means that Guardians will have until the weekly reset on 10 December — or 11 December here in Australia — to finish up any current season, Season of the Undying, tasks.
Bungie said it will detail more of Season of Dawn in the leadup to the big event. What do you reckon we’ll see in the meantime?
Destiny 2 is currently available on Windows PC, Xbox One, PS4 and Stadia.

thats ok...KMD is just frozen on that exchange
Bryan_Beus05-Jun-19 11:35 PM
Oh. If it's just that they've shut down activity, I wouldn't worry.
All exchanges are frozen, due to the hack.
Binance and Bittrex as well.
mrlynch05-Jun-19 11:39 PM
i'm afraid dp might have been affected
blubbi05-Jun-19 11:46 PM
i doubt dp using agama

pirate is safu
aka22205-Jun-19 11:55 PM
Hello friends
mrlynch05-Jun-19 11:55 PM
it was just kmd that was affected
aka22205-Jun-19 11:55 PM
Any update with the wallet details?
Hember06-Jun-19 12:03 AM
Help. It seems that there is a buch of zilla, milja and kmd on an address that shows in my agama wallet but which has this statement "you don't own priv keys for this address". What is this address and how do I claim the funds?
milja = ninja*
blubbi06-Jun-19 12:04 AM
ninja is a testcoin
Hember06-Jun-19 12:05 AM
yes, but there is still kmd and zilla on that address that I cant get my hands on
blubbi06-Jun-19 12:06 AM
it does
marcotonyja06-Jun-19 12:07 AM
any links to the latest version og agama lads please tnx
Hember06-Jun-19 12:07 AM
I mean, on my KMD Agama wallet there is an address which has locked (or something) somehow these assets, and the app says that I don´t own the priv key for that address.. I don't understand it... who then owns those keys?
Desktop App for SuperNET DAPPs. Contribute to VerusCoin/Agama development by creating an account on GitHub.
Hember06-Jun-19 12:09 AM
I donät own the private keys for the address. it is not about the app, it is about the address and.. I mean I can't try any other app if I can't get to the private kays.
oh no, This web browser app doesn't let me to share screenshots or pics... damn,...
marcotonyja06-Jun-19 12:13 AM
any link for the latest agma for kmd lads please tnx
think im in trouble anyway none of my kmd is showing in my agama..tryed taking it out today but would not let me
Hember06-Jun-19 12:17 AM
I can also reveal this address if that helps to browse the problem. According to asset viewer there is kmd, zilla, pizza, ninja and something else there.
leronira06-Jun-19 12:56 AM
Due to the vulnerability problem would coinomi or ledger wallet be safe for transferring KMD to?
Can I claim the 5% on those wallets?
Llama06-Jun-19 12:57 AM
my wallet funds haven't moved, but when I try to send them to my verus agama the transactions won't go thru
klein06-Jun-19 12:59 AM
Ledger is not affected and there a few ways you can claim the 5% rewards with it(edited)
leronira06-Jun-19 01:21 AM
For ledger it's the atomic labs method?
Oh nvm it's all in browser
Ranma10306-Jun-19 01:24 AM
Does anyone have the import command for Komodo Ocean to import my priv key
for a new address made in the Verus agama
jspook1606-Jun-19 01:26 AM
How do I send btc? I keep getting invalid public address error
Trying to get it out of my old agama wallet
NutellaLicka06-Jun-19 01:37 AM
@Llama if you're using lite mode, the electrum servers are being pumped by everyone trying to do the same. I believe if you try to turn the proxy off, and continue to try, you will get your order through
@Hember have you got the privkeys stored elsewhere?
Hember06-Jun-19 01:43 AM
I really do not know. That is just one of the many addresses. When I first made my Komodo wallet I probably stored a seed in my precious book, but I have that book elsewhere right now. You think it might solve the issue?
@Hember If you try and reimport the keys, that may work. Are you trying to move your funds out of an old agama?
Hember06-Jun-19 01:44 AM
Yes, that is what I am doing.
NutellaLicka06-Jun-19 01:45 AM
Yeah I would then try and reimport the privkey or rescan your wallet on opening (this may take a long while)
Hember06-Jun-19 01:49 AM
Yeah... I need to investigate further tomorrow. Already almost 5 am here.
NutellaLicka06-Jun-19 01:56 AM
@jspook16 sorry, misread your problem(edited)
Gordon Komodo06-Jun-19 02:00 AM
@Ranma103 it should be importprivkey "yourprivatekey"
NutellaLicka06-Jun-19 02:01 AM
@marcotonyja please provide us with more details so we can help out if you'd like
suhthern-girl06-Jun-19 02:01 AM
I think I've lost my KMD -- sent to a non-developer address.
Trying to create a new address on Windows 10...
(1) komodod.exe is running

suhthern-girl06-Jun-19 02:02 AM
Oh.... duh!
polycryptoblog06-Jun-19 02:03 AM
Can you share the address that you lost funds from , here or in DM
suhthern-girl06-Jun-19 02:05 AM
DM'd you.
jcooper06-Jun-19 02:21 AM
So I already opened verus agama with my old seed to check balances...now I can't create new seed
Can I send to kmd ocean?
NutellaLicka06-Jun-19 02:22 AM
Yeah you can
or CLI
Why can't you create a new address in verus agama?
kAOs71606-Jun-19 02:22 AM
I could use some guidance. Have tried reading previous posts but could not find my path
KMD stored on Agama v0.3.5-beta in Native mode - all there
Have installed Verus Agama v0.6.0-13 as suggested
Do I just create a new seed and transfer from old Agama to new Verus agama address?
I have another token on there as well - is it also affected?
NutellaLicka06-Jun-19 02:23 AM
Create a new SEED in the VerusHash Agama (important) And transfer the funds from the old agama to that one @kAOs716(edited)
jcooper06-Jun-19 02:23 AM
@NutellaLicka it doesn't have the "create new seed" on front page anynore
@NutellaLickai found it.

NutellaLicka06-Jun-19 02:24 AM
@kAOs716 any wallets that have been create/used/tx'd into KMD Agama in the last 6 months are at risk
Including all assetchains
kAOs71606-Jun-19 02:27 AM
thanks @NutellaLicka
bblurock06-Jun-19 02:35 AM
Ive created the new address and key using Verus Agama, while the Komodo Agama was installed, but the new key and address never touch Komodo agama. I uninstalled Agama after that. Would this be a problem?
jcooper06-Jun-19 02:38 AM
Ok. Anything I can do with pirates from old agama to new verus agama
PHBA206106-Jun-19 02:38 AM
as long as you new key doesn't enter in Komodo's Agama, then it's safe, but it doesn't hurt to take the extra measure and generate a new one after uninstalling Komodo Agama
jonnybbig06-Jun-19 02:44 AM
Can computer person help me? I deleted agama in os10.14.4 Mojave and when I open “activity monitor” it still says komodod using my system..I deleted all files I could find related
jspook1606-Jun-19 02:44 AM
I sent my btc to be very address. But I can't spend it
jonnybbig06-Jun-19 02:44 AM
Any idea where this komodod is found?
bblurock06-Jun-19 02:46 AM
Thanks @PHBA2061 , Im intended to do that, but gotta find a way to update that google form for the new address.
QuadraQ06-Jun-19 02:57 AM
Is it normal for a rescan of the KMD blockchain in native mode to take hours?
polycryptoblog06-Jun-19 02:59 AM
Yes
bblurock06-Jun-19 03:01 AM
Is there any way to update the claim form after closing it, or I can create a new submission?
suhthern-girl06-Jun-19 03:05 AM
When you folks are talking about creating a new "seed", are you simply talking about a new address or a new wallet seed?
NutellaLicka06-Jun-19 03:05 AM
Both, Mainly a new wallet address. Which requires a new seed. But this must be done on agama verus, not the KMD one
suhthern-girl06-Jun-19 03:06 AM
Right -- did it with CLI. Thanks
Oh, btw, what is PGT?
polycryptoblog06-Jun-19 03:07 AM

suhthern-girl06-Jun-19 03:08 AM
Was that air-dropped?
polycryptoblog06-Jun-19 03:08 AM
I believe so, to voters of peer2 in the 2018 election
suhthern-girl06-Jun-19 03:08 AM
Ahhhh. Thanks.
Oz Miner06-Jun-19 03:10 AM
Hi, I have Agama V 0.3.5. I'm trying to access my KMD and RFOX so I can send them somewhere else but i get this error "blockchain.address.get_balance". I have tried to disable the proxy server but i am supposed to have the newest version of Agama. Every time i click on the link to download the newest version of Agama it just takes me to the website to download Komodo Wallet.
NutellaLicka06-Jun-19 03:12 AM
Sounds like a problem with electrum servers. I would download the Verus Agama, create a new wallet address, import OLD privkeys in, and transfer them to your new wallet
The electrum servers are under the pump due to a lot of people using them
It may seem ridiculous, but it is a necessary thing to do. The team have provided ways to HELP you not lose your coins. The agama wallet provided a warning in their github This is experimental and unfinished software. Use at your own risk! No warranty for any kind of damage!
There were other options for wallets instead of Agama if this warning didn't suit you.
suhthern-girl06-Jun-19 03:16 AM
I sent PGT to new address, but it's giving me NaN errors -- hash doesn't match or something. Did I blow the wallet?
Ok. Wallet seems OK. Don't know what's going on with PGT, though.
dukeleto06-Jun-19 03:21 AM
Can somebody tell me the "rescue" addresses where james swept funds? I don't see the addresses listed in pinned posts, but there are so many
Oz Miner06-Jun-19 03:21 AM
Well I'm so glad the team has provided ways to HELP me not lose all my coins. Now if only i was a technical expert and not just an every day person.
dukeleto06-Jun-19 03:23 AM
@suhthern-girl it's normal to see some GUI errors like that when the backend server is overloaded
suhthern-girl06-Jun-19 03:23 AM
OK.
kAOs71606-Jun-19 03:24 AM
Still a bit confused here. I have both Agama and Verus Agama on the same pc. I was planning on starting Verus and generating a new seed and new address but Verus is reading the previous old Agama transactions....
polycryptoblog06-Jun-19 03:45 AM
Check that you are running Verus Agama, if so, kill all the Agama processes. Make sure to uninstall the Komodo Agama and generate new address with Verus Agama


Getting started with Typewriter is easy, give it a try by following the steps below.
You can download the Typewriter extension from the Visual Studio Gallery or install it inside Visual Studio from the Extensions and Updates menu by searching for Typewriter. You'll need to restart Visual Studio for the extension to load.
Typewriter is available for Visual Studio 2013 and later.
When Typewriter is installed it also adds a new file type to Visual Studio, TypeScript Template (*.tst). TypeScript Templates are available in the "Add new item"-dialog under the category "Web".
Add a new TypeScript Template named Models.tst and paste the following code in the new file.
module App { $Classes(*Model)[ export class $Name { $Properties[ public $name: $Type;] }] }
Add a C# class named CustomerModel.cs and paste the following code in the new file.
using System; using System.Collections.Generic; namespace Demo { public class CustomerModel { public int Id { get; set; } public string Name { get; set; } public ICollection<OrderModel> Orders { get; set; } } }
That's it, you now have a template that will track any changes to your C# code and when it finds a class matching the filter (*Model) it will automatically add, update or delete a corresponding TypeScript-file.
A new TypeScript file, CustomerModel.ts, have been generated and added to your project (under the Models.tst node in the Solution Explorer).
module App { export class CustomerModel { public id: number; public name: string; public orders: OrderModel[]; } }
The Typewriter code model is what you use to access metadata about your C# classes, properties, methods etc.
You access the code model by typing $
followed by a keyword e.g. $Classes
which will return all public classes.
Since $Classes
is a collection of classes you also need to add a template that will be repeated for each class by adding []
after the keyword e.g. $Classes[...]
.
Everything between [
and ]
will be repeated for each item in the collection e.g. $Properties[public $name: $Type;]
.
Primitive keywords like $Name
, does not require a template.
Filters are used to determine which C# files should be rendered by a specific template. Because of this all templates must have at least one filter, otherwise the template won't be rendered.
You can add a filter to any collection in the code model e.g. $Classes
or $Properties
.
Add a Filter by adding ()
between the keyword and the template e.g. $Interfaces(filter)[...]
.
The easiest way to add a filter is by using a simple filter. Simple filters are just strings with optional wildcards (*
) that matches the name or full name of the items in the collection.
So $Classes(*Models)[...]
matches classes ending in "Model" and $Classes(Application.Api.*Model)[...]
matches classes ending in "Model" and with a namespace that starts with Application.Api.
You can also filter on attributes and inheritance. Attribute filters are wrapped in []
e.g. $Methods([Route])[...]
matches methods with a Route
attribute.
Inheritance filters are prefixed by :
e.g. $Classes(:ApiController)[...]
matches classes that inherits from ApiController
. Inheritance filters also matches implemented interfaces.
In addition to the simple filters you can also use lambda predicates to create more advanced filters. e.g. $Enums(e => e.Name.StartsWith("Color"))[...]
You can extend the code model by adding custom methods to your template. To add a custom code block you type ${ }
at the beginning of the template.
Within this code block you can add using-statements and custom methods. Methods that take a single parameter of a code model type, e.g. Class
or Method
, will be available in the template.
${ string LoudName(Class c) { return c.Name.ToUpperInvariant(); } } module App { $Classes(*Model)[ export class $LoudName { // ... }] }
In this example $LoudName
will call the custom method.
Typewriter templates provide a settings API via the template constructor. The settings API allows you to specify which projects are included when rendering the template and configure the output filename and file extension.
${ Template(Settings settings) { settings .IncludeCurrentProject() .IncludeProject("Project.Name"); settings.OutputExtension = ".tsx"; } }
Typewriter provides extension methods for common tasks. To enable extension methods, add a code block with the appropriate using statement for the extensions you want to use.
${ using Typewriter.Extensions.WebApi; } module App { $Classes(:ApiController)[ export class $Name { constructor(private $http: ng.IHttpService) { } $Methods[ public $name = ($Parameters[$name: $Type][, ]) => { return this.$http({ url: `$Url`, method: "$HttpMethod", data: $RequestData }); }] }] }
In this example $Url
, $HttpMethod
and $RequestData
are extensions.

Autoware with LGSVL Simulator
Table of Contents
Launching Autoware alongside Simulator
General
This guide goes through how to run Autoware with the LG SVL Simulator.
This link leads to our fork of the ROS-based open-source software Autoware. The repository contains various fixes and changes on top of Autoware to allow running it with LG Silicon Valley Lab's Autonomous Driving Simulator.
This fork of Autoware is currently rebased on Autoware release 1.9.0.
In order to run Autoware with the LGSVL simulator, it is easiest to build and run a custom Docker image. It will also be necessary to clone LGSVL's autoware-data repository, which contains the HD maps, point cloud maps, and launch scripts needed to run Autoware in the simulator's default San Francisco environment.
Autoware communicates with the simulator using the rosbridge_suite, which provides JSON interfacing with ROS publishers/subscribers.
Setup
Requirements
- Linux operating system
- Nvidia graphics card
Docker image setup
We recommend using a Docker container to run Autoware. We do not currently provide an image on Docker Hub, so it is necessary to build the Docker image first manually.
Installing Docker CE
To install Docker CE please refer to the official documentation. We also suggest following through with the post installation steps.
Installing Nvidia Docker
Before installing nvidia-docker make sure that you have an appropriate Nvidia driver installed. To test if nvidia drivers are properly installed enter nvidia-smi
in a terminal. If the drivers are installed properly an output similar to the following should appear.

The installation steps for nvidia-docker are available at the official repo.
Building LGSVL Autoware Docker image
Cloning requires instaling Git LFS. If you do not already have Git LFS installed, follow these instructions.
Clone this repository to your home directory, making sure to checkout the lgsvl_develop
branch:
$ git clone --recurse-submodules https://github.com/lgsvl/Autoware.git -b lgsvl_develop
Build the Docker image. This should take some time.
$ cd autoware/docker/generic
$ ./build.sh kinetic
You should now have a Docker image named autoware-kinetic
.
We also need LGSVL's autoware-data repository, which contains map files and launch scripts for running with the simulator. This repository also uses Git LFS.
 Launch the container:
$ cd ~/autoware/docker/generic
$ ./run.sh kinetic
You should now be logged into the container under the username autoware
.
Simulator installation
Follow the instructions on our simulator Github page here.
Launching Autoware alongside LGSVL Simulator
To launch Autoware, first bring up the Docker container as described in the previous section.
Inside the container, run Autoware:
autoware@[MY_DESKTOP]:~$ cd ~/autoware/ros
autoware@[MY_DESKTOP]:~$ ./run
A few terminals will open, as well as a GUI for the runtime manager. In the runtime manager, click on the 'Quick Start' tab and load the following launch files from ~/shared_dir/autoware-data/my_launch_sf_map/
by clicking "Ref" to the right of each text box:
my_map.launch
my_sensing_simulator.launch
my_localization.launch
my_detection.launch
my_mission_planning.launch
my_motion_planning.launch
Click "Map" to load the launch file pertaining to the HD maps. An "Ok" should appear to the right of the "Ref" button when successfully loaded. Then click "Sensing" which brings up rosbridge.
Run the LG SVL simulator, choosing "SanFrancisco" map and "XE_Rigged-autoware" for Robot. After "my_sensing_simulator.launch" has been loaded, the simulator should show "Connected", showing that the simulator has established a connection with the rosbridge server.
Click "Run" to start, and a vehicle should appear in the streets of San Francisco. On the left, click the check boxes for "Enable GPS" and "Enable LIDAR".
In the Autoware Runtime Manager, continue loading the other launch files - click "Localization" and wait for the time to display to the right of "Ref". Then click "Detection," "Mission Planning", then "Motion Planning".
Then click "Rviz" to launch Rviz - the vector map and location of the vehicle in the map should show.
To see the vehicle drive, click "2D Nav Goal" in Rviz, then click a destination point and drag slightly in a feasible direction (in the direction of the driving lane) to give a goal destination pose to the planner. The vehicle should plan a path and begin driving towards the destination.
You should see something similar in RViz to the above when the vehicle successfully starts navigating using Autoware.

The science of sound and hearing
Krzysztof Basiński
What is sound?
Talk in groups (5 min.):
- What is sound from a physical perspective…
- …from a physiological perspective…
- … from a psychological perspective
Sound (Wikipedia)
- In physics, sound is a vibration that propagates as a typically audible mechanical wave of pressure and displacement, through a medium such as air or water.
- In physiology and psychology, sound is the reception of such waves and their perception by the brain.
Sound
Properties of waves
- Frequency
- Amplitude
- Speed of propagation
- What our ear percieves are changes in pressure over time
Frequency
- Measured in Hertz (Hz)
- 1Hz = 1 oscillation per second
- Humans percieve frequency as pitch (low / high)
- Humans hear frequencies between 20Hz and 20,000Hz (20kHz)
Amplitude
- Humans percieve amplitude as loudness
- Physical measure of loudness – SPL (sound pressure level)
- Averaged SPL – RMS
- Logarythmic SPL – dB (decibel)

Speed of propagation
- Air, sea level, 20 degr. C. - 343 m/s
- Water: 1482 m/s
- Steel: 5960 m/s
- The speed of sound plays a crucial role in auditory perception of direction and acoustical environment detection
Auditory scene
The game is this. Your friend digs two narrow channels up from the side of the lake. Each is a few feet long and a few inches wide and they are spaced a few feet apart. Halfway up each one, your friend stretches a handkerchief and fastens it to the side of the channel. As waves reach the side of the lake they travel up the channels and cause the two handkerchiefs to go into motion.
Your task
You are allowed to only look at the handkerchiefs and from their motions to answer a series of questions:
- How many boats are there on the lake and where are they?
- Which is the most powerful one?
- Which is the closest?
- Is the wind blowing?
- Has any large object been dropped suddenly into the lake?
Bregman’s analogy
This is a strict analogy to the problem faced by our auditory systems.
Auditory pathway
Auditory pathway
- Mostly bottom-up processing
- Rising complexity:
- Cochlear nucleus – 90,000 neurons
- Medial geniculate nucleus (in thalamus) – 500,000 neurons
- Auditory cortex – 100,000,000 neurons
- There are top-down pathways as well, as far back as cochlea
Frequency selectivity
- The cochlea is a bank of band-pass filters
- A combined output of these filters form the audible spectrum (20Hz-20kHz)
- This is called tonotopy
- The higher the frequency, the higher the band’s range
Tonotopy
Tonotopy
Auditory cortex
Auditory cortex
- Primary auditory cortex (core) -> secondary auditory cortex (belt) -> secondary auditory cortex (parabelt)
- Tonotopy - tones close to each other in terms of frequency are represented in topologically neighbouring regions in the brain
- Central regions in the core respond to lower frequencies, outer regions to higher frequencies
Auditory cortex
- Neurons respond not only to specific frequencies but also to (single cell recordings in cats):
- Changes in frequency (going up or down in pitch)
- Transients (abrupt changes in intensity) (as in /p/ phoneme or other plosives)
- Particular loudness levels (e.g. 30-50dB)
- Particular location in space (e.g. only 20°- 30° to the right)
- Combinations of loudness and location
Auditory cortex
- Hierarchical organization – neurons in the core respond to narrow freqs (e.g. 200Hz) while neurons in the belt respond to wider frequency bands (e.g. 200Hz-300Hz)
- Perhaps belt neurons sum together activity from various core regions
How sound is located
- Inter-aural time differences – sound arrives at one ear earlier that at the other
- Inter-aural intensity differences – sound at one ear is louder than at the other
How sound is located
- Distortions by the head and pinnae – our heads and pinnae act as equalizers, changing the frequency spectrum of the sound
- This change is different depending on where the sound is coming from
- Our brains develop an internal model of how sounds get distorted – head-related transfer function
- We adapt to our own pinnae shapes – when the shape changes we have problems with locating sounds
Loudness perception
Age and gender differences
Temporal summation
- Human hearing has evolved to be great at discerning sounds that are relatively long
- Very short sounds are perceived as quieter
- For example:
- For sounds lasting 200ms auditory threshold is about 16dB
- For sounds lasting 20ms the threshold is 26dB
Auditory masking


{% extends "header.html" %} {% block body %}
There are some questions that come up fairly often, and are things that were never actually explained to me either when I was first starting out. I thought it would be good to cover a few of those here!
The first one is this whole if name == main thing. Here's an example:
if __name__ == '__main__': print('such great module!!!!')
Here, I suggest you reference the video for a full example of how this works, but, basically, if name == main asks whether or not the script is the "main" running script, or if that script is just being referenced by another script. Whenever you import other people's code, they usually have these there, so that, when you import them, their code doesn't just automatically run.
Another curiosity people often have is this other bit of code placed at the top of scripts. Something like:
#!/usr/bin/python
This is what is known as the "shebang" line. It is used for Unix operating systems so the script will execute with Python. If you are on Windows, this is probably totally foreign to you!
Also, while not covered in the video above, I thought I should also add something I forgot to mention at all so far, and that's comments. You've seen my use of the # symbol. That works to create a single line comment like:
# this is a single line comment
You can also do multi-line comments like:
''' Multiple line comment, can use triple "double quotes" as well to do this.  ''')
I may add more to this page over time, but those should cover it. Those are things that I never saw in any tutorial (besides the comments), but I think they leave people confused.
