Single Node Setup
Purpose
This document describes how to set up and configure a single-node Hadoop installation so that you can quickly perform simple operations using Hadoop MapReduce and the Hadoop Distributed File System (HDFS).
Prerequisites
Supported Platforms
- GNU/Linux is supported as a development and production platform. Hadoop has been demonstrated on GNU/Linux clusters with 2000 nodes.
- Win32 is supported as a development platform. Distributed operation has not been well tested on Win32, so it is not supported as a production platform.
Required Software
Required software for Linux and Windows include:
- JavaTM 1.6.x, preferably from Sun, must be installed.
- ssh must be installed and sshd must be running to use the Hadoop scripts that manage remote Hadoop daemons.
Additional requirements for Windows include:
- Cygwin - Required for shell support in addition to the required software above.
Installing Software
If your cluster doesn't have the requisite software you will need to install it.
For example on Ubuntu Linux:
$ sudo apt-get install ssh
$ sudo apt-get install rsync
On Windows, if you did not install the required software when you installed cygwin, start the cygwin installer and select the packages:
- openssh - the Net category
Download
To get a Hadoop distribution, download a recent stable release from one of the Apache Download Mirrors.
Prepare to Start the Hadoop Cluster
Unpack the downloaded Hadoop distribution. In the distribution, edit the file conf/hadoop-env.sh to define at least JAVA_HOME to be the root of your Java installation.
Try the following command:
$ bin/hadoop
This will display the usage documentation for the hadoop
script.
Now you are ready to start your Hadoop cluster in one of the three supported modes:
- Local (Standalone) Mode
- Pseudo-Distributed Mode
- Fully-Distributed Mode
Standalone Operation
By default, Hadoop is configured to run in a non-distributed mode, as a single Java process. This is useful for debugging.
The following example copies the unpacked conf directory to
use as input and then finds and displays every match of the given regular
expression. Output is written to the given output directory.
$ mkdir input
$ cp conf/*.xml input
$ bin/hadoop jar hadoop-examples-*.jar grep input output 'dfs[a-z.]+'
$ cat output/*
Pseudo-Distributed Operation
Hadoop can also be run on a single-node in a pseudo-distributed mode where each Hadoop daemon runs in a separate Java process.
Configuration
Use the following:
conf/core-site.xml:
<configuration> <property> <name>fs.default.name</name> <value>hdfs://localhost:9000</value> </property> </configuration>
conf/hdfs-site.xml:
<configuration> <property> <name>dfs.replication</name> <value>1</value> </property> </configuration>
conf/mapred-site.xml:
<configuration> <property> <name>mapred.job.tracker</name> <value>localhost:9001</value> </property> </configuration>
Setup passphraseless ssh
Now check that you can ssh to the localhost without a passphrase:
$ ssh localhost
If you cannot ssh to localhost without a passphrase, execute the
following commands:
$ ssh-keygen -t dsa -P '' -f ~/.ssh/id_dsa
$ cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys
Execution
Format a new distributed-filesystem:
$ bin/hadoop namenode -format
Start the hadoop daemons:
$ bin/start-all.sh
The hadoop daemon log output is written to the ${HADOOP_LOG_DIR} directory (defaults to ${HADOOP_HOME}/logs).
Browse the web interface for the NameNode and the JobTracker; by default they are available at:
- NameNode - http://localhost:50070/
- JobTracker - http://localhost:50030/
Copy the input files into the distributed filesystem:
$ bin/hadoop fs -put conf input
Run some of the examples provided:
$ bin/hadoop jar hadoop-examples-*.jar grep input output 'dfs[a-z.]+'
Examine the output files:
Copy the output files from the distributed filesystem to the local
filesytem and examine them:
$ bin/hadoop fs -get output output
$ cat output/*
or
View the output files on the distributed filesystem:
$ bin/hadoop fs -cat output/*
When you're done, stop the daemons with:
$ bin/stop-all.sh
Fully-Distributed Operation

Before beginning this section, save the current text file as "sample.txt"
Once the file has been saved continue with these steps.
1) Select Notepad.exe > Faults > Disk in the Project Pane.
2) Select "File in Use" in the Faults Pane.
3) Verify failure
In notepad click File > Save, notepad will attempt to save the file to the same location as it had originally saved it. Since the "File in Use" fault is set, notepad gets an error and attempts to recover by asking you where else you would like to save the file, and give this error message.
After Clicking OK Notepad sluggishly shows the save dialog box. However if you try to save the file as something else, sample2.txt in this case, notepad fails to create the file again, as it is getting a file in use error for a file that has not yet been created.
4) Delete the fault
a) Without closing Notepad return to Holodeck
b) Delete the fault
c) Right click the fault and select Delete Fault
5) Notepad will return to normal execution once the fault has been lifted
Note: BrokenApp will continue to function normally; no fault has been set for this application.


Recipe 20.12. Using Cooperative Super calls with Terser Syntax
Credit: Michele Simionato, Gonçalo
Rodrigues
Problem
You like the cooperative style of multiple-inheritance coding
supported by the super built-in, but you wish you
could use that style in a more terse and direct way.
Solution
A custom metaclass lets us selectively wrap the methods exposed by a
class. Specifically, if the second argument of a method is named
super, then that argument gets bound to the
appropriate instance of the built-in super:
import inspect
def second_arg(func):
args = inspect.getargspec(func)[0]
try: return args[1]
except IndexError: return None
def super_wrapper(cls, func):
def wrapper(self, *args, **kw):
return func(self, super(cls, self), *args, **kw)
# 2.4 only: wrapper._ _name_ _ = func._ _name_ _
return wrapper
class MetaCooperative(type):
def _ _init_ _(cls, name, bases, dic):
super(MetaCooperative, cls)._ _init_ _(cls, name, bases, dic)
for attr_name, func in dic.iteritems( ):
if inspect.isfunction(func) and second_arg(func) == "super":
setattr(cls, attr_name, super_wrapper(cls, func))
class Cooperative:
_ _metaclass_ _ = MetaCooperative
Discussion
Here is a usage example of the custom metaclass presented in this
recipe's Solution, in a typical toy case of
"diamond-shaped" inheritance:
if _ _name_ _ == "_ _main_ _":
class B(Cooperative):
def say(self):
print "B",
class C(B):
def say(self, super):
super.say( )
print "C",
class D(B):
def say(self, super):
super.say( )
print "D",
class CD(C, D):
def say(self, super):
super.say( )
print '!'
CD( ).say( )
# emits: B D C !
Methods that want to access the super-instance just need to use
super as the name of their second argument; the
metaclass then arranges to wrap those methods so that the
super-instance gets synthesized and passed in as the second argument,
as needed.
In other words, when a class cls, whose
metaclass is MetaCooperative, has methods whose
second argument is named super, then, in those
methods, any call of the form super.something(*args,
**kw) is a shortcut for super(cls,
self).something(*args, **kw). This
approach avoids the need to pass the class object as an argument to
the built-in super.
Class cls may also perfectly well have
other methods that do not follow this convention, and in those
methods, it may use the built-in super in the
usual way: all it takes for any method to be
"normal" is to
not use super as the name of
its second argument, surely not a major restriction. This recipe
offers nicer syntax sugar for the common case of cooperative
supercalls, where the first argument to super is
the current classnothing more.

CURLINFO_TLS_SESSION explained
NAME
CURLINFO_TLS_SESSION - get TLS session info
SYNOPSIS
#include <curl/curl.h> CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_TLS_SESSION, struct curl_tlssessioninfo **session);
DESCRIPTION
This option has been superseded by CURLINFO_TLS_SSL_PTR which was added in 7.48.0. The only reason you would use this option instead is if you could be using a version of libcurl earlier than 7.48.0.
This option is exactly the same as CURLINFO_TLS_SSL_PTR except in the case of OpenSSL. If the session backend is CURLSSLBACKEND_OPENSSL the session internals pointer varies depending on the option:
CURLINFO_TLS_SESSION OpenSSL session internals is SSL_CTX *.
CURLINFO_TLS_SSL_PTR OpenSSL session internals is SSL *.
You can obtain an SSL_CTX pointer from an SSL pointer using OpenSSL function SSL_get_SSL_CTX. Therefore unless you need compatibility with older versions of libcurl use CURLINFO_TLS_SSL_PTR. Refer to that document for more information.
PROTOCOLS
EXAMPLE
CURL *curl = curl_easy_init(); if(curl) { CURLcode res; struct curl_tlssessioninfo *tls; curl_easy_setopt(curl, CURLOPT_URL, "https://example.com"); res = curl_easy_perform(curl); curl_easy_getinfo(curl, CURLINFO_TLS_SESSION, &tls); curl_easy_cleanup(curl); }
AVAILABILITY
Added in 7.34.0, and supported OpenSSL, GnuTLS, NSS and gskit only up until 7.48.0 was released.
RETURN VALUE
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.

Port of Valparaiso lies on the coast of central Chile about 100 miles northwest of the country’s capital, Santiago. The port lies on the shores where a coastal mountain range forms a rocky peninsula and a sheltered bay. Built on steep hillsides, Port of Valparaiso is a labyrinth of cobblestone alleys and streets. It is a treasure of cultural and architectural history.
Position 33°2.7' S, 71°37' W.
This is a Port of Entry. See Noonsite/Chile/Formalities for information.
This is Chile's busiest port. There are two mooring facilities in this harbour that welcome visiting sailors, though both anchorages are a little rolly. If coming from the South the first is Puerto Deportivo Valpariaso (located at the Baron Pier or Muelle Baron in Spanish) and then Yacht Club de Chile (on some charts named Yacht Club Recreo).
Just north of Valpariaso habour are two small and protected bays, also with welcoming yacht clubs. Club de Yates de Higuerillas (about 5 miles north) and the Club de Yates de Quintero (about 15 miles north of Valparaiso). Access to the splendors of Valpariaso is easy from either of these clubs via bus or train.
Sadly we have just had a report that both these yacht clubs have been destroyed by a storm, earthquake & tsunami.

Gaming, Then and Now
My brother is currently attending the DigiPen School of Technology working on a degree in video game programming / design. He's an avid gamer but has missed some of (IMO) the best games of all time, specifically, the Half-Life saga. Naturally, I email him recommending these games in the hope of inspiring him or, at the very least, giving him a better understanding of some of the good games he's missed out on and where the industry came from. I even offered to buy the games for him if he didn't want to pay for them himself. Well, he acquired the first Half-Life game and started playing it. This was his response:
Hey Chris, just wanted to let you know that I tried out Half-Life today.  I know a lot of people loved it, but I can't stand it.  I hated that I had to get really close to an enemy just to hit him, and when I did they would turn to me and hit me. It was very hard to hit the head crabs as well. By the way, yes, I know that I had a gun, but I had very limited ammo. Also, I hated virtually never knowing where to go or what to do. Some of the buttons that you need to push in that game are very tiny or off to the side where you can't see them. I know the game is old, but it seems very poorly designed to me.
This got me thinking, most modern games suck. These games are targeted at the general population, not the avid gamer. The AI are dumbed way down, there are big signs or floating arrows everywhere telling you which way to go, and the games are generally too easy.  Not to mention the story of most of these games are boring and do not engage the player. Now contrast this with the games from our youth. Most of these games were difficult and many didn't give you any clear path to follow. Here's a list of several games I enjoyed playing when I was younger.
- Any Super Mario Bros. Game pre 1990
- Battletoads
- Duck Hunt
- Metroid
- Super Metroid
- Legend of Zelda
- Zelda: A Link to the Past
- Zelda: Occarina of Time
- Super Mario RPG
- Sim Ant
- Sim City
- Doom
- Heroes of Might and Magic
- Perfect Dark
- Command & Conquer: Red Alert
- Star Craft
I could go on. Compared to modern games almost all of these games were relatively hard, had few if any clear paths to take and some even had things that would kill you instantly (Bowsers fireballs). Also, many other early NES games were nearly impossible to beat without the use of cheats or game altering devices (See the AVGN).  To this day I've never beaten the original Mario Bros, Battletoads or Metroid, yet I still enjoy playing them from time to time regardless of their difficulty.
In a world where there's several new (shitty) games out every week and many of those titles have a sequel released within a year, I truly appreciate game companies like Valve and Gearbox and the independent developers like Notch and fear for a future where game developers don't enjoy, or at least respect, the games that we/they have grown up with.

This
seems to be a very general slot for
comments on the data, the project, the processing. I'm not sure how
this would fit into the data discovery arena. Could just be used as
text to feed into a free text search (extension to summary?). I.e., how
would this be mapped into THREDDS metadata (maybe documentation). |
| summary |
More general than a summary. |
|
| acknowledgement |
I don't see a place for this in CF. Maybe comment. |
|
| history |
history |
Pretty direct mapping from CF to this proposal. How compare with processing_level? |
| institution |
creator_name creator_url creator_email |
Good semantic mapping to/from CF (in proposal, creator can be individual or institution).
However, the more structured nature of the creator_* attributes might
cause problems with an actual mapping to/from the more free text nature
of the institution attribute. |
| contributor_name contributor_role |
Another possible mapping (contributor can also be individual or institution). |
|
| id naming_authority |
Not good match. The id/naming_authority pair is
intended to provide a "globally" unique ID for a dataset; doesn't have
to be related to creation of dataset. |
|
| project |
Kind of one level above creator/institution. More of a "why was this dataset created" rather than "where was it created". |
|
| summary |
The summary is intended as a human readable
description of the dataset that can be used in free text searches.
Should probably contain creator/institution information. |
|
| references |
references (add to proposal?) |
Certainly good information to have but I'm not sure how this would be used in data discovery. |
| source |
source (add to proposal?) |
Seems like this would be a good addition to the
proposed attributes. This information should probably also be in the
summary attribute. |
| processing_level |
As Jonathan said, this is a bit vague. However,
some places have specific processing level terminology. Do we want to
allow for specifyingcontrolled lists of values? |
|
| project |
I think project fits better in the creator/institution area than source. |
|
| summary |
The summary is intended as a human readable description of the dataset that can be used in free text searches. Should probably contain source information. | |
| standard_name |
standard_name |
Direct mapping between CF and this proposal. The
only change is to allow use of non-CF standard name values (which
should only be done if the CF convention is not being followed). This
is done by indicating in the standard_name_vocabulary attribute the name
of
the variable name controlled vocabulary that is being used. ???: For a CF file, values must be from CF standard name table. Do we want to allow CF compliant files to have alternate "standard names"? If so, need to not use "standard_name". |
| title |
title |
Direct mapping between CF and this proposal. |
| time_coverage_* geospatial_* |
Some points from Jonathan: 1) can deduce info from coordinate variables; 2) need to be rewritten if subselection is made. We do need some way to bubble this information up to tools that harvest dataset discovery information that won't be CF aware (some digital libraries won't even be all that data aware). We're also looking (in THREDDS) at containing this info at the catalog level. So, maybe that is a better solution. |

PRISON DEATH
Steven Donaldson killer found dead in Perth prison as co-accused have appeals to reduce their sentences rejected
by Aidan SmithTHE killer of Steven Donaldson has been found dead in HMP Perth - as his co-accused saw appeals to reduce their sentences rejected.
Steven Dickie is believed to have taken his own life and was discovered by prison officers overnight.
A SPS spokesperson said: "Steven Alexander Dickie, 24, a prisoner at HMP Perth has died.
"He was convicted at Edinburgh Court on 30 May 2019.
"Police Scotland have been advised and the matter reported to the Procurator Fiscal.
"A Fatal Accident Inquiry will be held in due course."
Dickie's death came as Tamsin Glass and Callum Davidson appealed their sentences for culpable homicide and murder.
Both had their appeals rejected.
Donaldson's sister Lori said: "We're glad the appeal was rejected. We were in agreement with the sentence from the beginning.
"It was horrible seeing them again, it was horrible having to go through it again.
"We are just glad it is done and we got the outcome that we wanted."
Earlier this year Dickie was given a life sentence for murdering oil worker Mr Donaldson.
Donaldson's body was discovered in the car park at Kinnordy Nature Reserve near Kirriemuir, Angus, in the early hours of June 7 last year.
Detectives said the 27-year-old from Arbroath had been the victim of a "sustained and brutal attack".
Dickie and Davidson were convicted in May of murdering the offshore worker following a trial at the High Court in Edinburgh.
The pair, both 24, were jailed for life when they returned to the court.
Glass, 20, who was an ex-girlfriend of Donaldson was told she would be caged for 10 years after being convicted of culpable homicide.
The trio planned to launch an attack at the quiet park before driving Steven to the Kinnordy Nature Reserve where they killed him.
Graphic evidence from a forensic pathologist detailed the extent of the horror injuries inflicted on Donaldson - which included severing his spinal cord in two places.
Prosecutors believe the pair used an axe or machete type weapon to inflict the killer blows but these weapons were never recovered.
After killing him the pair then set fire to his car in an effort to hide any evidence.
The jury spent more than nine hours in their deliberations.
Eventually they found both Davidson and Dickie guilty of murder.
Meanwhile, Glass was found guilty of culpable homicide.


--- layout: post title: "Functor relationships" description: "Sometimes you need to use more than one functor together." date: 2022-07-11 8:09 UTC tags: [Software Design] --- {% include JB/setup %}
{{ page.description }}
This article series is part of a larger series of articles about functors, applicatives, and other mappable containers. Particularly, you've seen examples of both functors and applicative functors.
There are situations where you can get by with a single functor. Many languages come with list comprehensions or other features to work with collections of values (C#, for instance, has language-integrated query, or: LINQ). The list functor (and monad) gives you a comprehensive API to manipulate multiple values. Likewise, you may write some parsing (or validation) that exclusively uses the Either functor.
At other times, however, you may find yourself having to juggle more than one functor at once. Perhaps you are working with Either values, but one existing API returns Maybe values instead. Or perhaps you need to deal with Either values, but you're already working within an asynchronous functor.
There are several standard ways you can combine or transform combinations of functors.
The following relationships often come in handy - particularly those that top this list:
This list is hardly complete, and I may add to it in the future. Compared to some of the other subtopics of the larger articles series on universal abstractions, this catalogue is more heterogeneous. It collects various ways that functors can relate to each other, but uses disparate concepts and abstractions, rather than a single general idea (like a bifunctor, monoid, or catamorphism).
Keep in mind when reading these articles that all monads are also functors and applicative functors, so what applies to functors also applies to monads.
You can use a single functor in isolation, or you can combine more than one. Most of the relationships described in this articles series work for all (lawful) functors, but traversals require applicative functors and functors that are 'foldable' (i.e. a catamorphism exists).
Next: Natural transformations.


Unregistering
Because these bugs are very hard to track down and very easy to avoid, I’d like to direct everyone’s attention to how to properly unregister for notifications.
If your object uses NSNotificationCenter ever, you must add the following to -dealloc:
[[NSNotificationCenter defaultCenter] removeObserver:self];
This removes you from all notifications. If you fail to do this, and you are dealloc’ed, and a notification you were observing is later posted, the application will crash with a bizarre access violation deep in NSNotificationCenter when it tries to post to an object (you) which no longer exists. It is tricky to figure out even what notification is being passed in these cases.
If you are not observing anything, then -removeObserver: does nothing, so it is not dangerous to call. There is a slight performance cost, especially for objects that are alloc’ed and dealloc’ed a lot, so there’s no reason to add it to objects that do nothing with notifications, but I recommend better safe than sorry in most cases.
This advice does not apply to KVO observations, which are a completely different animal.
Naming
While here, it’s worth noting some other significant notification advice. Never pass a hard-coded string as the name; you’re begging for hard-to-track-down bugs when you mistype the string elsewhere. Create a name in the form PREFIXSomethingDidHappenNotification, for example: RNFooDidChangeNotification.
Then create a constant with this name. In .h create an extern (a promise to define it elsewhere):
extern NSString* RNFooDidChangeNotification;
And in .m, define it (outside of your @implementation block):
NSString* RNFooDidChangeNotification = @"RNFooDidChangeNotification";
Please make the name of the notification match its value; it will make your debugging much easier. While many constants begin with a “k”, notifications do not, and delegate method naming conventions suggest they shouldn’t, so please don’t.
The object of a notification should generally be the object that posts the notification, and in any case should whenever possible be a “watchable” object (i.e. an object that the observer could have a pointer to). This means that the object shouldn’t be created dynamically when the notification is posted (an NSNumber or NSValue for instance). Other kinds of objects should be passed in the userInfo dictionary with appropriate keys (which should also be defined as variables as above). In the above example, the observer would strongly expect the object to be of class RNFoo.
When do notification run
For those coming from Java or C++, the actual handling of notifications often is a mystery. If you’re used to highly threaded environments, you’re immediately wondering about timing issues like “what if I receive a notification in the middle of other processing?” In Objective-C, these issues (mostly) disappear.
-postNotification: (and the related methods) deliver notifications immediately. This is nothing like a Java JMS. -postNotification: is really just a fancy way to make a method call. As soon as you call it, the NSNotificationCenter walks through all the observers and calls all the selectors, one at a time. Only when it has finished them all does -postNotification: return. There is no extra thread. These are just method calls, and you will see them in your stack trace as though the poster called you.
A side-effect of this is that you aren’t going to get random notifications in the middle of your processing. As long as you keep all your notifications on the main thread (which you should do), they will always come in synchronously.
What if you realy want to delay processing of a notification? Look at NSNotificationQueue. This will let you post notifications that get processed at the next event loop.
(Advanced issues) NSNotificationCenter responds to notifications on the thread that the notification was posted on, not the thread the notification was observed on. In multi-threaded envrionments this can be confusing. Generally the right answer is to respond to all notifications on the main thread. To achieve this, use -performSelectorOnMainThread:withObject:waitUntilDone: to call -postNotification: if the poster is on its own thread. If the observer needs to be on its own thread, it is best to let the notification come in on the main thread, and then have the observer’s handler perform the -performSelector:onThread:withObject:waitUntilDone: to get the processing over to the correct thread. This way, multiple observers can have their own threads, which would not work if the poster performed the -performSelector:onThread:withObject:waitUntilDone:.

Dear Sir/Madam, I got your contact from an email directory and decided to contact you for assistance. I am the son of JOHNSON SAVIMBI the rebel leader in Angola who was short dead on the 25th of February, 2002, by the opposing Angolan Army. PLEASE TAKE A LOOK AT THIS WEB PAGE FOR IT SAYS ALL. http://news.bbc.co.uk/hi/english/world/africa/newsid_1839000/1839252.stm Before the death of my father he deposited 16M (Sixteen million dollars) with a security company in Europe as valuables. All the legal documents for the deposit are with my mother which my father gave to her for safe keeping. After the death of my father I and my family fled to South Africa where we are currently living. And we have been trying to fly to Europe but it has been difficult for us to get visas from Africa. So we want you to help us make claims of this fund ($16m) in Europe as my family beneficiary and transfer the money to your account or any account of your choice before I and my family can get visas to fly down to your country so that we can share this money. My family have agreed to give you 10%, which would be ($1.6Million dollars) of this Money for your assistance, and 87% would be for us and the other 3% would be set aside for any expenses that we may incure during the course of this transaction. And part of our share of 87% would be invested in your country in any profitable business proposed by you. While a large part of our share will also be used to help charity organizations. We have never met, but I want to trust you and please do not let us down when this fund finally gets into your account. Please if you are interested; get to me through my email address to enable me feed you with more details and all necessary documentations. Please treat this as confidential. Best regards, JOHNSON SAVIMBI


Businessman tasks Nigerians on fighting corruption
by BankoleMr Zubair Idris the Project Manager, Wadata Communications Nigeria Limited, has called for active participation of Nigerians in the fight against corruption for the development of the country.
Idris made the appeal during a public forum to commemorate World Anti-Corruption Day on Thursday in Abuja.
Also read: Anti-graft war: People with clear conscience should not be apprehensive – Lamido
He said no that nation can witness development without eradicating corruption, urging all hands to be on deck in the fight against corruption.
“We can make a change in our country by ensuring active participation in the fight against corruption.
“The citizens should resist, report and discourage corrupt practices by refusing to participate in corrupt practices through a change in public attitude on corruption,” he said.
The project manager urged Nigerians to resist the system of celebrating corruption by those that have stolen the country’s wealth.
On his part, Dr Abubakar Kari, Dean Student Affairs, University of Abuja, called on Nigerians to speak out against corruption in fighting the menace which has eaten deep into the fabrics of the country’s socio-economic development.
Kari, a guest speaker on the topic “The occurrences of corruption within the University system”, urged all citizens to discourage corruption in the country.
According to him, it is not enough to set up anti-corruption agencies in the country, but adequate sensitisation from the family and community levels will reduce corruption in society.
He said fighting corruption should be a socialisation process through training, from schools, market places, worship centres and traditional institutions.
“The fight against corruption requires all individuals and social groups in society to join hands and fight corruption.
“The campaign will communicate to Nigerians what they stand to gain personally by adopting a corruption averse mentality,” he said.
The dean also urged community leaders, individuals and non-governmental organisations to embark on adequate sensitisation of the public.
The News Agency of Nigeria (NAN) reports that the International Anti-Corruption Day is observed annually on Dec. 9, since the passage of the United Nations Convention against Corruption, to raise public awareness on anti-corruption.

Doctor! You have to drain the blood
before proceeding with treatment!
This is the same strain of GUILT
that Ms. Reid contracted.
Let's begin.
The Kyriaki is causing these
lacerations... Treat those first.
There it is!
Cut near the shadow to expose it.
Ugh... I still can't stand looking
at that thing... Use the laser!
The laceration treatment is going
well. Nice work, Doctor.
Here they come... Stay calm, and
use the ultrasound.
The patient's vitals are dropping!
You have to suture those wounds!
One Kyriaki incinerated...
Keep up the good work.
...That's the third one.
How many are there?
Another laceration! It must be
the large Kyriaki, like before.
Use the ultrasound to draw it out
of hiding, then burn it away.
It must be hiding... Use the
ultrasound to find it!
Great work... It's over, Derek.
The Chiral reaction is negative.
Great work... It's over, Derek.
The Chiral reaction is negative.
Let's treat those last few wounds
and close him up.
...You were testing for chirality?
We were, Angie.
That's very observant of you.
GUILT creates cells with an
unnatural chirality.
Using the Chiron Test, we can detect
the specific wavelength they emit.
So far, that's the only way to
reliably distinguish GUILT.
Remind me to give you the Chiron
Test equipment, later.
Sorry I wasted all that time, Derek.
Finish up by suturing the incision.
Excellent work. I can see why
my brother recommended you.
This is really bad...
We need to hurry!
Those spots are tumors from the
GUILT. Burn them off with the laser.
Continue with the tumors.
No complications yet...
That large tumor must be creating
the smaller ones! Attack it, first!
Our data indicates the Deftera
could appear at any time...
When the Deftera combine to form a
tumor, use the drain to remove them.
That's the plan...
...Are you ready?
There! Those are cells created by
this strain of GUILT--Deftera!
You shouldn't ignore those tumors.
Incinerate them right away.
The Deftera have formed a tumor.
Drain the tissue quickly!
The Deftera's cell count is steadily
decreasing, as expected.
Continue the drainage... We'll be
able to excise it soon, I hope.
Chiral reaction is dropping!
It... stopped moving...?
It's out of control! We have to
get it out of there!
The Deftera solidified!
We should be able to excise it...
Excision complete! You've removed
the GUILT from her stomach.
Excision complete! You've removed
the GUILT from her stomach.
We'll move to the lungs, next.
First, finish treating these wounds.
***{4807}{6F08}***
***{4807}{6F08}***
Y-You did it, Doctor!
Amy's going to be okay!
...It's a miracle...
We'll move to the lungs, next.
We're counting on you, Dr. Stiles.
C'mon, Derek...!
Save my little sister!
Please perform a lobectomy.
There are two pairs of Deftera!
Careful of those with like colors...
It's solidified... You should try
excising it, now.
One set of Deftera has been removed.
...Please proceed with caution.
The GUILT has been eradicated!
Chiral reaction is negative.
The operation was successful.
The GUILT has been eradicated!
Chiral reaction is negative.
The operation was successful.
*sigh* Good work, Doctor. Treat
the other wounds and close her up.
...Thanks, Derek...
...Thank you so much...
I respect that.
Amy should have a smooth and
painless recovery...
Derek... I owe you, man. ...How can
I ever repay you for all this?
This is serious, Derek. You'll need
to do exactly what I say.
...This bomb design is archaic.
The trigger device is a pair of
small water tanks.
We'll need to find a way to deal
with those tanks before moving on.
Dismantling it shouldn't be too
hard... Well, it's possible, anyway.
We shouldn't waste any more time...
Let's get down to business!
What are you doing!?

We're dismantling a BOMB, here.
...Use the magnifier.
That's a good idea. We need to
magnify this for precision.
Okay, let's check this out. Magnify
the lower right water tank.
We can't do anything this way!
Try magnifying the area.
Being precise is a good idea--keep
using the magnifier...
Let's get some magnification on
the lower right tank.
This is a trigger device. If it
detects a change in the water level,
the bomb explodes. This gimmick's
been around since ancient Rome.
It's also a timer. See--the water
flows slowly from left to right...
when the left tank empties, and the
right one's full, it explodes.
We might be able to work around this
using the drain. Let's try it out.

Now move to the left tank, and
release the water.
Yeah, like that.
The water level is constantly
changing--keep an eye on it.
So...that takes care of the trigger,
let's move on to the explosive.
Stop magnification so we can see
the entire bomb.
Those brown rods are dynamite.
...They won't explode on their own.
I assume those silver boxes are
supposed to ignite the explosives.
They're not operating right now...
Either they failed, or it's a trap.
But, if that changes, it could cause
the dynamite to explode.
Let's take care of the dynamite
before that can happen.
Here, magnify the area around
the dynamite.
Okay.
Pull each one out--carefully.
Okay, let's begin.
See that yellow part at the end of
the dynamite? That's a detonator.
Basically, if the detonator's gone,
the dynamite shouldn't explode.
If we disable the explosives, then
the igniter is probably useless.
So, we just need to pull out the
detonator on each stick of dynamite.
...And, that's how to dismantle this
bomb. That's not so bad, right?
Try pulling the detonators upward
with your forceps.
***{4807}{6F08}***
That's the wrong side! You have to
transfer it from right to left!
That's the wrong side! You have to
transfer it from right to left!
 You
have to keep some in the tube.
I just told you...don't dispose of
the water you're draining.
There's not a lot of time left...
Move on to the explosives.
Cease magnification.
Magnify the right tank. That's where
we'll need to be working.
Magnify the sticks of dynamite.
Hurry, we're running out of time!
We need to keep working...just be
careful of the trigger device.
This will affect the rest of the
bomb. Magnify, then laser the chips.
Magnify it, first. We're history
if you hit the wrong chip.
What's...going on?
The laser can short out these chips,
but I think...
Don't mess with the chips that are
connected to the explosives.

So just be careful. Only laser the
chips connected to the temp gauges.
This is probably related to the
trigger device underneath it!
If we destroy the microchips, then
the trigger should deactivate.
Follow that pattern--destroy ONLY
the chips that connect down below.
Don't touch that until I can figure
out what it does...
Follow the pattern so you can laser
the chips for the trigger device.
Okay...so much for the trigger
devices. Time for the explosives.
One trigger down! Move on to
the others.
The trigger devices are deactivated.
Now, let's stop those explosives.
Use your forceps to lift the
detonators upward.
Apply antibiotic gel--that should
lower the temperature of the device.

Check the board above it.
You need to alternate between gel
and injection to have any effect.
Pull the detonator upward using
the forceps.
All detonators have been removed.
Now, to handle the trigger device.
We'll have to adjust the water
level periodically.
The dynamite's been nullified,
so don't worry about that.
The left tank is empty, but the
dynamite's been nullified.
The right tank is too full, but
the dynamite's been nullified.
Hm... This is bad. The trigger
device has been activated.
When the temperature level hits MAX,
the explosive will go off!
The chips on this board operate
the trigger somehow...
If you follow the wires, we should
be able to deactivate it.
Remember that antibiotic gel will
lower the temperature, too!
Hm... This is bad. The trigger
device has been activated.
When the temperature level hits MAX,
the explosive will go off!
I think you can lower its
temperature by using the gel...
but we have to shut it off, somehow!
Where's it being controlled from?
You're cutting it too close--
transfer water between the tanks!
The temperature is too high!
Hurry up and lower it!
...*sigh* The trigger devices are
dismantled... Good job, Derek.
Wh-What the--!?
Another trap?
They really thought this through!
Cut the red cords, Derek!
Use the scalpel!
Phew... We should be safe now.
Glad that's over... Talk about your
bad patients...heh...
We have to shut it down! Something
has to be controlling it...
This is bad! Hurry up and take care
of that trigger!
Unfortunately, Doctor... There's a
storm up ahead...
They're going to try to avoid as
much turbulence as possible...
...but this is far from an ideal
operating environment.
Try not to let the shaking of
the plane distract you, Dr. Stiles.
Respiratory failure is serious--we
need to finish this quickly.
Try using the ultrasound to locate
an ideal draining area.
Ugh... It's turbulence...
I hope it settles down soon...
Eeeeeek!
It stabilized...
If the plane starts shaking again,
it could cause a lot of problems...
...We might need to stop operating
temporarily until it lets up.
It stabilized...
We should probably stop operating
when the turbulence picks up...
...Especially if you're using a
scalpel... That would be terrible.
Make sure you suture any wounds that
occur during the turbulence.
It's settled down...
We need to drain the area as soon
as any shaking starts...
...See? The whole area's inflamed
because the liquid spread around.
Treat it by injecting an
anti-inflammatory.
I think it settled down...
We need to drain the area as soon
as any shaking starts...
...See? The whole area's inflamed
because the liquid spread around.
Inject the anti-inflammatory and
suture the wound that opened up.
The fluid is causing inflammations!
Inject the anti-inflammatory.
Another wound...
You need to suture it!
This is difficult to handle. Please
use the injection and suture it.
This is a good area for drainage.
Make an incision across the shadow.
There's a lot more fluid here than
there should be...!
Drain it immediately, before
we hit more turbulence!
We've drained all we can from here.
Please make another incision...
Drainage is about half complete.
Please continue.
*sigh* Patient's breathing has
stabilized.
He should be okay, for now.
Let's finish up the treatment.
*deep breath* I guess we did it.
Oh! They're applauding...
...Tch, don't let it go to your
head, Dr. Stiles...
We've never dealt with GUILT like
this before, so be careful...
What the...heck? A membrane, and...
...these look like thorns!
...What!? Could they have known
about...?
What is it, Dr. Miller?
...Stiles, I think the membrane
is causing this disease.
Any organ covered by that membrane
will be slowly petrified...
We need to detach it immediately.
Use the scalpel.
Hold on... You won't be able to
detach it that way.
Don't you see the thorns? They've
fastened the membrane to the organ.
...I think you're right.
If we can remove all three thorns
on one segment, there's a chance
we could excise it.
That's quick thinking, Angie! You
should consider Caduceus Europe.
...Anyway, try pulling the thorns
out with your forceps.
Okay, it's out...! Now, try
removing thorns from all three
corners. That should allow us to
excise a triangular section.
She's right, Stiles! You should be
able to get it with a scalpel!
...What? It re-formed!? I guess
the thorns regenerate over time.
The thorns reappeared. You're going
to have to move quickly, Dr. Stiles.
The thorns re-formed. You need to
remove them again right away.
The membrane is spreading again...
It will multiply if left alone!
What the...? Quickly, Stiles!
Drain it!
No wonder the town was destroyed...
...It's highly contagious.
If we inhale that vapor, we'll all
be in danger. ...Careful, now!
If the vapor touches an organ,
it forms another membrane.
What's wrong, Doctor? We have to
remove the membrane!
You excised the membrane--now use
the forceps to remove it.
The membrane is spreading...
You can't grab it haphazardly.
I see... Those thorns are causing
the GUILT to spread...
Th-They are? How can you tell?
...A while ago, our country tried
using similar technology to fight
organs that had become cancerous--
shards which vibrate at high
frequencies to stabilize the cancer
tissue for removal.
...It creates a hardened membrane
exactly like this one.
This strain of GUILT seems to be
modeled after our treatment.
Those thorns are releasing
frequencies to petrify the organ.
Dr. Stiles, we need to try removing
them all at once.
...There has to be some pattern
to it. Keep an eye on the membranes.
We've removed part of the membrane!
If we can keep this up...!
It didn't multiply that time...
Keep it up, Dr. Stiles!
Ugh, I don't think that's it.
The membrane multiplied again.
Wait! I think they multiply when
two thorns are close to each other!
That shining purple section is
making me uneasy...
It's causing a serious decline in
his vitals.
If possible, we should excise
that purple membrane first.
We're doing a good job...stay alert
until we're completely finished.
I think you have it, Dr. Stiles!
Hang in there...
We did it! Chiral reaction is
negative!
Amazing! You really can operate
successfully against GUILT!
Sir... You were surprised that
they knew about...something?
I'm afraid this GUILT...was derived
from one of my country's sins.
As I said earlier, we were trying
to create a treatment for cancer,
using high-frequency vibrations.
But...there were complications.
Our treatment couldn't differentiate
between cancerous cells and healthy
ones, so it simply attacked
them all.
We wanted a way to help people,
but we found a way to kill them...
And, apparently, Delphi found out
about it. ...That's what I meant.
Let's close up the patient.
Reuben should be fine, now.
Don't drop the membrane, or it
could re-attach. Be careful!
Impressive, Dr. Stiles. It seems
that GUILT is no match for you...
I'd say you've more than earned
your place in Caduceus.

I wonder about myself all the time - I suppose many people do (wonder about themselves, that is). I came to this page and DevBootcamp through the demands of curiosity. I've always enjoyed my brief experiences programming but never learned about it with much depth or practicality, and this seemed like a good opportunity to embrace both.
Outside of this, I dabble in music, figure skating, finance, drawing, photography, and whatever else I can remember. I mostly grew up in York, PA and went to college in Philadelphia. Then I spent three years in New York City, which I found overall pleasant but economically inefficient for me. I moved to Chicago in July 2014, and so far I've been enjoying the tasty regular food and the city's bikeability.
I like dogs and frogs (I eat neither), meeting strangers, and wordplay. My name is non-phonetic and is pronounced like "Helene."

The thesis contributes a new auto-scaling system that can be adapted to any cloud platform. It proposes a new monitoring system that collects relevant metrics to make important scaling decisions. Using the collected metrics, the design aims to provide an efficient feedback to the cloud DevOps. The collected feedback is integrated into the development environment so that developers are able to utilize the feedback to make their applications better scalable and highly available. On the other hand, this feedback can also be used to automate configuration management and to facilitate dynamic infrastructure provisioning. In this thesis, the monitoring metrics are aggregated for a sufficient period to make scaling decision. Scaling decisions can depend on a single metric or even a combination of metrics that can be customized by the cloud application developer.
The thesis also models the monitored information collected by the monitoring component of the auto-scaler, to identify a suitable correlation model. The model provides a better understanding of the relation between the collected metrics.

I had the wonderful opportunity of working as a web developer for HackFSU 2016, during which I gained many fun late night memories of working on the site at Domi Station with the TechNole & HackFSU crew, as well as knowledge of working on the front-end of a Node.js framework for our judging web app. I collaborated with a team of developers to build HackFSU 2016's judging app, which I contributed to using Jade, CSS, and Javascript.
Unfortunately, my GitHub account was not configured properly with my local Git repo at the time, so my contributions do not show online. However, if you are interested in learning how we built the app, click here to see our now publicly available source code!
This was the third HackFSU that I have been a part of (2nd time as a coordinator) and I am thankful to have contributed to a product that will be used at future hackathons!


Sentry is an interactive speaker designed to nudge people out of their daily routine by bluntly presenting the ubiquitous and implicit social pressures around them.
It invades personal space by hanging at head level, uses a motion sensor to detect when people walk nearby, flashes LED strips to get attention, speaks authoritatively with dual integrated speakers, and retracts up and out of sight with a hidden winch system.
Implemented on the UC Berkeley campus, Sentry underscores our implicit submission to capitalist values–specifically those having to do with the technology industry of the Bay Area–by encouraging students to derive self-worth solely from their success in the tech scene.
Sentry was created with the help of Tiffany Tao and Felix de Rosen, my partners for the first provocation of the spring 2020 Critical Making class at UC Berkeley.
Sentry was built over the course of a week. The enclosure was cut from stained birch with frosted acrylic inserts. Internal electronics include two WS2812b LED strips, a PIR motion sensor, two 1W speakers, and a high-torque pulley modified to be continuous rotation, all driven by a Feather 32u4 Bluefruit LE and LiPo battery.

How can small organization run relays on the Tor network while sustain their operations
The Tor network consists entirely of relays run by volunteers, providing bandwidth and other services to Tor users. There are currently about 6000 relays sustaining the network [1]. Up to now the Tor network has grown organically, by the mean of community outreach activities. Tor relay operators are usually individuals that are motivated by various factors. The Tor project mission itself is a strong driver for individuals interested in providing privacy enhancing communication tools to people all over the world. Other relay operators might be researchers interested in the technical aspects of the Tor software and protocol. Others can also simply be open source entusiasts that want to be part of its community. Many relay operators have often been recruited, so to speak, by other community members or core developers. Finally some relay operators are adversaries that are trying to run different analysis over the Tor network itself, like collecting information on its use or on the content being transferred.
All the motivations described above do not require direct compensation by the Tor Project and the volunteer-based approach to sustain the network has been proved successful. Relay operators do not only invest their hardware, but also time and commitment in running the relays and in being part of the Tor community. Expenading the set of relays is vital for the Tor network. More importantly the network needs a diverse set of relay, not just advertised bandwidth. Diversity means different hardware and operating systems, but also different locations across the globe in order to reach users worldwide and offer overall the same quality of service.
Throughout Tor history, there have never been in place an official mechanism for relay operators to be rewarded extrinsically. The intrinsic reward of being a relay operator was the social perceived value, like recognition within the Tor community. Many different proposals have been made for a Tor incentives system [2], but none has ever been implemented.
Relay operators sometimes create a small non profit or join an umbrella organization, to support their activities. These are setup so that the individual operators are not legally responsible in case of a legal dispute. Also the organization is setup to share the burden of possible legal expenses and to collect donations for their activities. The Tor Project itself advises people to constitute a non-profit organization responsible for the relays in case of possible legal disputes. There are some legal risks in fact associated with running relays. These are usually not different from the same risks that an ISP could have since both relay internet traffic. Exits relays have more legal concerns that bridges, guards or middle relays, because middles and guards only relay encrypted traffic, while exits performs requests to the open internet. The Tor Project provides some standard response letters that relay operators can use and some legal resources that could become handy. In any case relay operators are advised to consult with a lawyer if any problem with law enforcement should arise.
Running a relay can be as cheap as a few dollars per month and as expensive as a few hundred, depending on where the relay runs, which kind of hardware it's running on, bandwidth, operating system and so on. Most relays operators rely on donations from individuals that want to contribute to the network but for several reasons are not able to run a relay at the moment. There is again intrinsic value to donate to relay operators to contribute to the Tor community.
A big portion of relay costs are taken over by bandwidth consumption. If an individual or group wants to run a node that relays a lot of traffic, bandwidth might become expensive.
Certain mechanisms developed by and for the maintenance and operations of the Tor network have much in common with off-grid utility implementation. To start both are ipso-facto decentralized, community based and require experimenting with different business models for implementation.
A number of previous studies have developed their own classifications for electrification models.
[3] describes different participatory models for off-grid electricity services in rural areas. Drawing from previous defined classification systems, they identify five models with different types of operations that have been used in rural electrification.
One thing that differentiate the ecosystem of companies and cooperatives providing utilities and relay operators is the fact that while utility providing organizations could in theory charge its users for using their network, the Tor network is freely accessible by everyone running a Tor client. Since neither the Tor Project nor any reasonable relay operator would like to charge Tor users for bandwidth used, in the past people have speculated whether it would make sense to build mechanisms so that the network could reward relays for the bandwidth provided to the network. A part of this speculation has also involved considering possible harms of such mechanism to both the privacy and security of Tor users and the community of relay operators. For example some have argued that this could encourage bad or malicious relays, or the growth of relay farms with the only interest to cash out instead of maintaining the network and protecting the privacy of its users.
Some relay operators groups have developed a membership model to help sustain their operations [4] [5]. The membership model allows such group to build a close relationship with their supporters while also sustaining their operations.
While relay operators cannot be directly compensated by Tor users directly, they could be compensated for offering other services in a participatory way to the community of Tor users and .onion websites. The relay operators group could add a certain fee to the service offered and redirect part of this compensation to sustaining their infrastructure and work in maintaining the Tor network. This mechanism could help both the relay operators and the Tor network itself in more than one way. One the one hand relay operators can build a relationship with their members by offering a set of privacy friendly services that might or might not use the Tor network itself to be operated, like bridges, .onion hosting, vpn, and so on. On the other hand the Tor project will benefit by seeing more diverse use of the Tor network. Finally, this could also be an incentive for creating a better experience for onion services developers and operators and therefore fostering a more legitimate onion service ecosystem.
This mechanism could be easier to implement for some relay operators that other form of financing, simply because they are already running some of these services as these are needed for day-to-day operations. For example many operators group running exit are already running an authoritative dns and could easily offer this service to their members (some in fact already do). This might actually be easier in many circumstances than applying for international grants or public funding, since in many cases this suppose a big overhead in work that small relay operators group cannot sustain.

I use yubikeys to store my gpg and ssh keys.
Before starting do a little bit of reading to familiarize yourself with the setup procedure. I have added a list of links at the end. These are mainly the resources that I used.
I have generated my keys on a qube VM without internet connection.
$ gpg --gen-key
Selected option 0 and moved on to create my ID associated with the key.
In this step I used mostly the guide from yubico developers website [1] The guide goes through generating Sign (S) Authentication (A) and Encryption (E) keys.
$ gpg --expert --edit-key 123ABC45
At this step we select another RSA key to attach to our key. In the gpg selection menu this corresponds to option 8.
Here is where you should backup your keys and revocation certificates. Please do I have personally lost yubikeys and having backups really helps.
Also setup a PIN and a admin PIN for your yubikey [5]. With:
$ gpg --card-edit
$ gpg/card> admin
Finally we edit our key and add it to the keycard [1].
$ gpg --expert --edit-key 123ABC45
$ gpg> keytocard
Now your key is exported to your card and ready to be used.
$ gpg2 -K --with-keygrip
This will show all your keys available with keygrip.
Use the keygrip of your authentication key to export it to sshcontrol
echo 1234567AB8CDFFF90G9H1I23JJ4K5L67M89N012O > ~/.gnupg/sshcontrol
I have also added the following to my ~/.gnupg/gpg-agent.conf
[4]:
default-cache-ttl 600
max-cache-ttl 7200
enable-ssh-support
write-env-file ~/.gpg-agent-info
And edited my ~/.bashrc
with:
gpg-connect-agent /bye
export SSH_AUTH_SOCK=$(gpgconf --list-dirs agent-ssh-socket)
You can now:
$ source ~/.bashrc
$ ssh-add -l
This should list your new key.
A lot of information is given away by certain properties of communications beyond just the content. These properties are usually referred to as communication metadata. Metadata include information such as the lenght of the conversation, who was involved, where are the parties involved in the conversation located, and so on.
Questions that can be answered by looking at metadata are:
As you see Metadata give a lot away about you even if the actual content of your communication is encrypted. We could also say that the metadata can give away more information than reading the actual content, and in a form that is easily processed by machines.
Tor is an important tool providing privacy and anonymity online. The property of anonymity itself is more than just providing an encrypted connection between the source and the destination of a given conversation. Encryption only prevents the content of the communication between two parties from becoming known, but there is a lot of information that can still be learned by just observing the traffic.
When you use the Tor network, you are not sharing your communication metadata. So that, not only your communication are encrypted, but you can also stay anonymous. Anonymity is a broad concept, and it can mean different things to different groups.
The main advertised property of the Tor network is that it provides strong anonymity given a variety of people using the network. For the Tor network to function properly and to satisfy users' needs, we need a certain degree of diversity. We need diversity in the relays comprising the network and in the user population sending traffic through it. We want Tor to be able to reach and serve a diverse population of users and use cases. We believe everyone should be able to browse the web and enjoy privacy, independently of where they live and who they are.
But hiding network traffic is not all you have to do to be protect websites and services from tracking you online. There is a lot of information that is given away when you use your google or facebook accounts to login to a third party service.
The risk in this case doesn't only involve you transferring your profile information to a third party service, but also Facebook and Google learning about how and which third party services you use.
Tor provides a technology called onion services that allows users to offer various kinds of services, such as web publishing or an instant messaging server making that available on the Tor network. Using Tor "rendezvous points," other Tor users can connect to these .onion services, formerly known as hidden services, each without knowing the other's network identity.
An .onion service needs to advertise its existence in the Tor network before clients will be able to contact it. Therefore, the service randomly picks some relays, builds circuits to them, and asks them to act as introduction points by telling them its public key. By using a full Tor circuit, it's hard for anyone to associate an introduction point with the .onion server's IP address. While the introduction points and others are told the onion service's identity (public key), we don't want them to learn about the onion server's location (IP address).
In a-not-so imaginary more privacy friendly web, applications could be made available through onion services and we could use different identity providers that wouldn't necessarly need to access and share all our data, therefore without us losing control over our online footprints.
Recently I have have learned about Solid. Solid can be defined as a set of protocols leveraging on the idea of the semantic web to allow online applications to access user data. Building on top of hypermedia protocols, Solid is completely compatible with the current technologies of the web. With Solid all your data are stored in an online Solid Pod. The data is owned by the user who is always free to move it as they wanted.
Users can give other users or services permission to read or write to their POD. This approach is great for services' developers while also protecting user privacy. Ultimately the user retains control on their pod.
I have created a test application running on onion services and connecting to a solid community pod. This example is particularly interesting, because by using the .onion protocol the solid pod doesn't know about the app retrieving data. They will just see their .onion address.
The code is available via the myonion wrapper. An experiment in making available through docker containers different app via .onion services.
In this post I have shown how a web application made available through .onion on the Tor network can exchange information with a Solid pod and allow a user to login and share some data. Because .onion services live on the Tor network, you do not need hosting or a public ip address to offer some service via .onion address. This means .onion services are a gateway to a decentralised, peer-to-peer internet, where you regain control on the content you create and who you are sharing it with. The .onion can even be hosted on your computer for the time you desire, allowing the people using your service to remain anonymous, and also you.
I believe anonymity to be very important since it can free people, allowing them to decide how to expose themselves or to make themselves visible on their own terms.

There are a lot of JavaScript MVC frameworks out there. Why did we build React and why would you want to use it?
React is a library for building composable user interfaces. It encourages the creation of reusable UI components which present data that changes over time.
Traditionally, web application UIs are built using templates or HTML directives. These templates dictate the full set of abstractions that you are allowed to use to build your UI.
React approaches building user interfaces differently by breaking them into components. This means React uses a real, full featured programming language to render views, which we see as an advantage over templates for a few reasons:
We've also created JSX, an optional syntax extension, in case you prefer the readability of HTML to raw JavaScript.
React really shines when your data changes over time.
In a traditional JavaScript application, you need to look at what data changed and imperatively make changes to the DOM to keep it up-to-date. Even AngularJS, which provides a declarative interface via directives and data binding requires a linking function to manually update DOM nodes.
React takes a different approach.
When your component is first initialized, the render
method is called, generating a lightweight representation of your view. From that representation, a string of markup is produced, and injected into the document. When your data changes, the render
method is called again. In order to perform updates as efficiently as possible, we diff the return value from the previous call to render
with the new one, and generate a minimal set of changes to be applied to the DOM.
The data returned from
render
is neither a string nor a DOM node – it's a lightweight description of what the DOM should look like.
We call this process reconciliation. Check out this jsFiddle to see an example of reconciliation in action.
Because this re-render is so fast (around 1ms for TodoMVC), the developer doesn't need to explicitly specify data bindings. We've found this approach makes it easier to build apps.
Because React has its own lightweight representation of the document, we can do some pretty cool things with it:
<canvas>
instead of HTML.Backbone.Router
. Designers regularly contribute React code with JSX.Head on over to https://reactjs.org to check out what we have built. Our documentation is geared towards building apps with the framework, but if you are interested in the nuts and bolts get in touch with us!
Thanks for reading!


THE WAR ROOM a film review by Tak Placed in the public domain 1994 by Mark Takacs
An October Films Release / 96 mins film by: DA Pennebaker & Chris Hegedus Featuring: James Carville & George Stephanopoulos Tak Rating: watch it on cable
TV-Style-One-Line-Summary ------------------------- You-are-there documentary of Clinton's Presidential campaign, focusing on James Carville & George Stephanopoulos as they lay out strategy, do damage control, and cope with daily difficulties.
Tak Summary ----------- The film begins tracing the efforts of the War Room -- Clinton's campaign headquarters -- in the New Hampshire primary, and leads us all the way through the last days of the election. We see phone interviews, bull sessions, staff meetings (equally as boring as any I've ever been to), pep talks, behind the scenes convention footage, spin-doctoring, scandal shunting and attempts to leak a story.
Instead of focusing on Clinton, like the film-makers originally intended, the focus was shifted to THE WAR ROOM staff, specifically James Carville and George Stephanopoulos. Bill Clinton is rarely shown. It ends up as a study of THE WAR ROOM and the two people who successfully guided it.
Tak Thoughts ------------ I generally don't like documentaries. They remind me of high school social studies classes where half the class is sleeping and the other half is doing last night's homework for math next period. I always managed to learn something though, I just never enjoyed the format. The same goes for THE WAR ROOM.
I did get an interesting look at how a campaign runs. Anyone who thinks a political campaign is a model of order, organization and efficiency will be disillusioned after this film. Bill Clinton's "well-oiled political machine" is chaotic, headless-chickens running-around, seat of the pants group like any other group that needs to respond dynamically to rapidly changing information while still presenting a unified, organized and dignified front. Only the efforts of Carville and Stephanopoulos lend the mess any direction. While usually hellish to be involved in, such chaos is great to watch.
Repeatedly during the campaign, THE WAR ROOM staff has to deal with mudslinging from other candidates and questions about Clinton's past. These include draft issues, Jennifer Flowers, and college activist organizations. With some of these same issues plaguing Clinton today, it's interesting to realize that some of the same people (Stephanopoulos at least) are still at work defusing and directing policy.
The human elements are THE WAR ROOM's best point. That and the LACK of narration. Seeing the excitement after the debates, seeing the tense final days when everything is topsy turvy, seeing their depression when a news story is suppressed, seeing their reactions on the last day as it slowly dawns on them that they've done it. These are the things that made the film watchable.
There's some great lines here too. And you know they're not scripted... they're real lines. After a phone interview -- "I bet I said something you could take out of context" -- Bill Clinton. The sardonic Carville has several; my favorite regards Perot's expensive campaign -- "That's gotta be the single most expensive act of masturbation...". And Stephanopoulos after the election results are in -- "Now we have to actually do something..."
One thing I can't figure out -- how do they expect to make money on this film?  The husband and wife team of Pennebaker and Hegedus were dead set on making a feature length film, but who were they making it for? Who's the PAYING audience? Perhaps people who hang out in coffee shops and talk about politics? (Admittedly, there's a glut of those here in Seattle -- maybe they're on to something...) But still. Maybe they've got a sweet side deal with video.
Technical Comments ------------------ Of course, I knew THE WAR ROOM was a documentary and didn't expect steady-cams and special lighting effects. Accordingly, documentary fans will be happy with the obligatory running-with-the-camera footage, as well as dialogue volume swells, and rough manual pans as they flip back and forth between speakers. I think they actually added to the behind-the-scenes feel.
How did they film a 96 min movie while still maintaining a behind the scenes feel? According to the press packet, the film was done without huge lights and sound booms. No one was ever asked to "say that again for the camera", and the cameraman often lurked in the corner of the room, rather than crouching at people's feet.
In fact, the war room staff often forgot the small film and sound crew was there, often asking incredulously "You guys were filming? We thought you were waiting..." But you'd never know from seeing the movie. The film and sound crew got some great stuff from their unobtrusive locations.
Additional footage was culled from unused bits of a film called FEED, which covered the 1992 NH primary, and from network TV source tapes. The network excerpt were great. It was fun to see a TV reporter being jokingly (?) cut down by his interviewee moments before she and he start their standard schtick -- "This is Joe Blow reporting to you live with ..."
Tak Rating system: ------------------ Documentaries are interesting, but I'm not sure this works well as a feature film. It's not really a date film, a Saturday afternoon matinee, or even late night cable. I wouldn't be surprised to find something like this on your local PBS channel, or some of the better cable educational channels. Actually, if you're in high school or taking a poly-sci class, this would be a GREAT excuse for a field trip. Maybe you can even get it paid for as an official activity. If not, you can at least munch some popcorn and get out of the classroom.
avoid at all costs X watch it on cable wait for videotape see once as a matinee see several times (w/friends) as matinee see once at full price see it several times - full and/or matinee see many times at full price

{% extends 'layouts/base.html' %} {% block title %}Why Docker{% endblock %} {% block heading %}
Docker should not be hard for data science. Most docker guides are aimed at web development rather than for python or R applications.
The reason we will use Docker for our microservices is because it encourages us to keep individual processes small, rather than drifting to monolithic implementations.
At the end of the day, Docker is just a tool to set up a lightweight linux interpretter that has as few files as possible.
These running interpretters are known as containers. A docker image contains the instructions to build these containers. These images can be downloaded from Docker Hub, which is Docker's image registry.
Verify Docker works. Go to Command Line and execute:
docker --version
As of the time of writing, this returns:
Docker version 20.10.7, build f0df350
Run your first python image. Go to command line and type:
docker run -it python:3.8
This command does three things:
Dockerfiles are the instruction files for building a given container. You can write your own Dockerfile for an application, or just use one directly pulled from Docker Hub.
The python:3.8 Dockerfile can be found on GitHub here: https://github.com/docker-library/python/blob/dbf2083938bd54ddb0f8697c177d5ccfc927f20f/3.8/buster/Dockerfile
We can see that the Dockerfile for python:3.8 has the associated CMD of 'python3'. This means that when we run the image in interactive mode (the -it flag), we will be inside the python interpretter within the container.
To instead enter the container with sh, we call:
docker run -it python:3.8 sh
This drops us into the command line of the container. Inside of this container, we can launch python by simply typing 'python'. We also have access to pip.
Note that this container contains no files from your local system. It is up to us to get our application files into the container so that we can run them through our interpretter. There are three ways to do this.
Different components of the application likely have different dependencies. For this example, we define four broad microservices:
Each of our four microservices will operate within their own container. This means they can be run with completely different interpretters. ETL might use Spark or pure SQL, Preprocessing might use R Tidyverse, modeling might use python with scikit-learn, and dashboarding might use R Shiny.
These can be scheduled and executed independently from one another. For this example, we assume that ETL runs daily. We assume that preprocessing and modeling occur once a week. And we assume that the dashboard service is continually available.
Our ETL will rely on using Selenium to perform a webscrape for us in python. Our Preprocessing will use R Tidyverse. Our Modeling will use TPOT with python. And our Dashboarding will use R Tidyverse.
Let us assume that all our microservices will need to share some files. For this example, let us assume that the ETL drops a file into a data directory. The preprocessing service operates on this file. The modeling service imports the preprocessed file and then dumps predictions to the same data directory. And finally, the dashboard unionizes the predictions with the predictors and publishes visualizations based on this dataset to a server.
Because our microservices will all need access to this directory, we will use a Docker named volume that stores all this information for us. We will demonstrate how to upload data into a named volume in the first microservice, which uses R for preprocessing.
