Truman lives so we don't have to
The Truman Show A Film Review By Michael Redman Copyright 1998 By Michael Redman
***1/2 (out of ****)
At some point in nearly everyone's life, one begins to wonder exactly how real his perception of the world is. Usually between the ages of 30 and 40, most people realize that they have been looking at life through glasses made of lenses ground first by their parents, then by teachers and continually by the media.
Then there is the painful choice of accepting that view or attempting to get out of the box that surrounds us and form our own vision. No wonder that time of life is often referred to as a mid-life crisis.
 Beginning with a studio light that mysteriously falls out of the perfect blue sky and followed by odd "coincidences", he begins to believe that the world is revolving around him. In real life this would be called paranoia or delusions of grandeur. Here it's because, unbeknownst to him, Burbank is the subject of a 24 hour a day television series: the most popular show in the nation.
Adopted by a corporation at birth, his life has been broadcast to the world since his day one. Now at day 10,909, he's discovered that something is amiss. Everyone -- his wife, his best friend, the bus driver -- in his flawless hometown of Seahaven (filmed in the sanitized Florida community of Seaside) is an actor.
Even the town is a movie set with 5,000 hidden cameras under a huge dome. The sun and moon rise and set by command of series director Christof (Ed Harris who stepped in after Dennis Hopper left), he of the godlike name. All of Truman's experiences and emotions are manipulated by Christof's whispers to the actors. Truman lives in the ultimate fascist state.
An actress extra is yanked from the set when she and Truman begin to form an attachment to each other because it wasn't in the script. While she is trying to tell him that his life is a fake, she is hustled away by an actor playing her father.
The movie owes much to "The Prisoner" television series, but the show within the film reminds me of the slow-speed OJ Simpson car chase. Perhaps the best television ever, the extended chase was riveting because it was real and because nothing was happening, yet all eyes were on the tube. In this film, viewers watch Truman going about his mundane day. He leads an idyllic life and, like the chase, nothing much takes place...until he opens his eyes.
The audience watches him working, eating and sleeping. They give up their lives (in one scene a baby screams while its parents ignore him, glued to the set) to watch Truman eat dinner. We have become a country of voyeurs enjoying the bread and circuses.
Strangely enough with all of the overly-long films recently, this one feels too short. I wanted to know more. It is frustrating that the movie ends on the brink of potentially the most interesting aspect of Truman's life. Like the television audience, I want to watch. Although turning in a marvelous job, director Australian Peter Weir ("Picnic At Hanging Rock", "Witness", "The Year Of Living Dangerously") is a bit heavy-handed with the metaphors. It's obvious that the film is about our media-manipulated lives and the struggle to escape the shell of control. A more subtle approach would have worked better.
Weir has a history of casting actors (Harrison Ford, Robin Williams, Mel Gibson) in films that change their careers. Jim Carrey is no exception. Moving from his hilarious television work in "The Duck Factory" and "In Living Color" to the money-making but remarkably insipid "Ace Ventura" films, Carrey made his living with broad comedy and a rubber face. Taking a chance in the daring but flawed dark comedy "The Cable Guy", he signaled a change in direction. Now with "The Truman Show", Carrey has completed his about-face. Reining himself in, the actor is still hilarious at times, but there's a human here not just a goofball.
The supporting cast is up to the task. Each walks the fine line between portraying a television character and portraying an actor playing a character. The standout is Harris as the all-powerful megalomaniac on high.
The promotion of this film must have been a challenge. It was ready for release last year, delayed for a few months and then delayed again. The studio has decided to advertise it as a comedy. People who walk into the theater expecting to see nonsensical Carrey antics are going to be surprised.
It's much easier to watch someone else than to have our own experiences. It's seductive to be concerned about others because then we don't have to worry about looking at ourselves. And then when we are in a time of crisis, someone else's life can flash before our eyes.

Background and introduction
BACKGROUND: Security Problem of Estimation
Safety Critical Industries
- High safety requirements.
- More vulnerable System
- Modern control systems are becoming more open to the cyber-world.
- More complex threats on estimation algorithms.
- System equation and measurement equation:
$$
x(k+1)=Ax(k)+w(k),
$$
$$
y(k)=Cx(k)+v(k)+a(k),
$$
where $x(k)\in{\color{var(--myred)}{\mathbb{R}^n}}$, and
$$
y(k)\triangleq \begin{bmatrix}
y_1(k)\\
\vdots\\
y_m(k)
\end{bmatrix}\in {\color{var(--myred)}\mathbb{R}^m}, C\triangleq \begin{bmatrix}
C_1\\
\vdots\\
C_m
\end{bmatrix},
a(k)\triangleq \begin{bmatrix}
a_1(k)\\
\vdots\\
a_m(k)
\end{bmatrix}
$$
- Measurement equation of sensor $i$:
$$
y_i(k)=C_ix(k)+v_i(k)+a_i(k).
$$
- process noise $w(k)$ and measurement noise $v(k)$ are bounded: $\|w(k)\|_2\leq\mathcal{B}_w $, $\|v(k)\|_2\leq\mathcal{B}_v $.
- $(A,C)$ is observable. Note that $(A, C_i)$ is not necessarily observable.
- Target : $\|\hat{x}(k)-x(k)\|\leq \text{Constant}$ for all admissable attacks. (Consider unstable $A$ for non-trivial.)
Preliminaries on Local Observable Subspace Decomposition
$$A=\begin{bmatrix}
\lambda_1 &0\\
0&\lambda_2
\end{bmatrix}, \quad
C=\begin{bmatrix}
1 &0\\
0&1\\
1 &1\\
1&2
\end{bmatrix}.$$
Define that the observable space w.r.t. sensor $i$ as $$\mathbb{O}_i\triangleq {\rm span} \{C_i^\top , (C_i A)^\top, \cdots, (C_i A^{n-1})^\top \}.$$
We find that
$\mathbb{O}_1={\rm span}\{e_1\}, \mathbb{O}_2={\rm span}\{e_2\},\mathbb{O}_3={\rm span}\{e_1, e_2\}, \mathbb{O}_4={\rm span}\{e_1, e_2\} $,
where $$e_1\triangleq \begin{bmatrix}1& 0\end{bmatrix}^\top , e_2\triangleq \begin{bmatrix}0& 1\end{bmatrix}^\top $$
Preliminaries on Local Observable Subspace Decomposition
$$A=\begin{bmatrix}
\lambda_1 &0\\
0&\lambda_2
\end{bmatrix}, \quad
C=\begin{bmatrix}
1 &0\\
0&1\\
1 &1\\
1&2
\end{bmatrix}.$$
We find:
Sensor 1 can observe state entry 1.
Sensor 2 can observe state entry 2.
Sensor 3 can observe state entry 1,2.
Sensor 4 can observe state entry 1,2.
There are only 4 observability possibilities for one sensor:
(1) Can observe no entry. (2) Can observe entry 1.
(3) Can observe entry 2. (4) Can observe entry 1,2.
Preliminaries on Local Observable Subspace Decomposition
Assumption 1
All the eigenvalues of matrix $A$ have geometric multiplicity 1.
Theorem 1
If Assumption 1 holds, the observable space of a sensor has a group of canonical basis vector. Thus, a sensor either can observe a state entry or not.
[1]Mao, Y., Mitra, A., Sundaram, S., and Tabuada, P. (2022). On the computational complexity of the secure state-reconstruction problem. Automatica, 136, 110083.
Define the observability relationship matrix $\mathcal{Q}$ is constructed by
$$
[\mathcal{Q}]_{i,j}=\begin{cases}
0, e_j\notin \mathbb{O}_i\\
1, e_j\in \mathbb{O}_i
\end{cases}.\qquad
$$
Define sensor $i$'s reduced-order subsystem as $(\tilde{A_i}, \tilde{C_i})$, it is observable. (linear system with $n_i$ states, 1 sensor)
Local Observable Subspace
$$A=\begin{bmatrix}
\lambda_1 &0\\
0&\lambda_2
\end{bmatrix}, \quad
C=\begin{bmatrix}
1 &0\\
0&1\\
1 &1\\
1&2
\end{bmatrix}.$$
The observability relationship is recorded in a 0-1 Matrix $\mathcal{Q}$:
Local Observable Subspace
$$A=\begin{bmatrix}
\lambda_1 &0\\
0&\lambda_2
\end{bmatrix}, \quad
C=\begin{bmatrix}
1 &0\\
0&1\\
1 &1\\
1&2
\end{bmatrix}.$$
The observability relationship is recorded in a 0-1 Matrix $\mathcal{Q}$:

Example on Resilient Fusion
For 4 local observer states:
$$\tilde{x}^1\in\mathbb{R}^1,
\tilde{x}^2\in\mathbb{R}^2,
\tilde{x}^3\in\mathbb{R}^1,
\tilde{x}^4\in\mathbb{R}^2
$$
Fuse those subsystems by taking median:
Secure Estimation Algorithm against static sparse attack
Lemma 1
If the system is $2p$ sparse observable, then $\hat{x}(k)$ above has uniformly bounded error under static sparse attack where ${\rm supp} \{a(k)\}\subset \mathcal{C}$.
$$
\|\hat{x}(k)-x(k)\|_\infty\leq {\rm Constant}\qquad \qquad \qquad \quad$$
$2p$ sparse observable: System is still observable after removing arbitrary $2p$ sensors.
Secure Estimation Algorithm against static sparse attack
Lemma 1
If the system is $2p$ sparse observable, then $\hat{x}(k)$ above has uniformly bounded error under static sparse attack where ${\rm supp} \{a(k)\}\subset \mathcal{C}$.
$$
\|\hat{x}(k)-x(k)\|_\infty\leq {\rm Constant}(\mathcal{B}_w,\mathcal{B}_v,A,C,L_i) $$
$2p$ sparse observable: System is still observable after removing arbitrary $2p$ sensors.

Secure Estimation Algorithm
Step 1: update local observer state.
$$\tilde{x}^i(k+1)=(\tilde{A}_i - L_i \tilde{C} ) \tilde{x}^i_+ (k)+L_i y_i(k)$$
Secure Estimation Algorithm
Step 2: For each state entry, take median among all local states that can observe them.
Secure Estimation Algorithm
Step 3: Check compatibility of all those local estimates for each sensor $i$, state entry $j$:
$$
\tilde{x}^i_j:=
\begin{cases}
\tilde{x}^i_j, \text{ if } \|\tilde{x}^i-\hat{x}\|_2\leq (\sqrt{n_i}+1)\gamma \quad \textcolor{blue}{\rm (keeps\ the\ same) }\\
\hat{x}_j, \text{ if } \|\tilde{x}^i-\hat{x}\|_2> (\sqrt{n_i}+1)\gamma \quad \textcolor{red}{\rm (reset) }
\end{cases}
$$
Main result on secure estimation (Theorem 2)
Assume the system is $2p$-sparse observable and the following two conditions hold:
(1)
$\sigma_{\max}\left(\tilde{A}_i-L_i\tilde{C}_i\right)\leq \frac{1}{2\sqrt{n_i}+1}$, $i=1,2,\cdots,m$.
(2) The initial estimate satisfies $\|\hat{x}(0)-x(0)\|_\infty\leq \gamma$.
Then our algorithm provides a secure state estimate $\hat{x}$ in the sense that
$$\|\hat{x}(k)-x(k)\|_\infty \leq \gamma,\quad \forall k\in\mathbb{Z}^+.$$
Simulation on IEEE 14 bus system
generator bus $\mathcal{V}_g=\{1,2,3,6,8\}$, load bus $\mathcal{V}_l=\{2,3,4,5,6,9,10,11,12,13,14\}$
$14\times 2=28$ states (phase angle, angle velocity)
$14\times 4=56$ measurements (phase angle$\times 2$, angle velocity, electric power)
$$ \dot{\theta}_{i}(t) =\omega_{i}(t), $$
$$\dot{\omega}_{i}(t) =-\frac{1}{m_{i}}\left[D_{i} \omega_{i}(t)+\sum_{j \in \mathcal{N}_{i}} P_{t i e}^{i j}(t)- P_{i}(t)+w_{i}(t)\right].$$
$$ \left[\begin{array}{ccc}
y_{i_1}(k) & y_{i_2}(k) & y_{i_3}(k)& y_{i_4}(k)
\end{array}\right]^\top=\left[\begin{array}{ccc}
P_{e l e c, i}(k) & \theta_{i}(k)& \omega_{i}(k) & \omega_{i}(k)
\end{array}\right]^{\top}+v_{i}(k), $$
Attack set design
The attack set loops for every 3 time steps.
Random signal attack
$a_i(k)$ is a random value uniformly distributed in interval $[-10,10]$.
Slope signal attack
$a_i(k)=k/5$ i.e., the magnitude of injected data increases 20 for every second.
Estimation performance under random attack signal
Estimation performance under slope attack signal
Residue decrease by resetting
Residue decrease by resetting
Summary
Propose an algorithm for time-varying $p$-sparse attack on sensors.
Algorithm structure
Step 1: local observer update
Step 2: median fusion
Step 3: Detection and reset
Requirements
Condition on observability (closer to fundamental limit)
Non-derogatory dynamic matrix $A$
Results
secure estimation $\|\hat{x}(k)-x(k)\|_\infty\leq \gamma$.
No false alarm.

Description: We've created an app for the dog lovers out there. The app allows a user to locate and get directions to both dog friendly restaurants and dog parks in a given location. Usage: A user will visit the site, enter a location that they want to explore, decide if they would like to drive or walk and click the submit button. This event triggers the yelp API finding dog friendly restaurants and parks in the area. Once the user clicks on a location, the google maps API will populate the imbedded map with walking or driving directions to the desired location.
We will be building an app that allow the user to build a database for their favorite ski resorts allowing them to add/delete and modify the list. Using API's we will provide snowfall information and travel time to destinations in the list. Allow user to search and order list by snowfall(have fallen/forecast/current conditions/temp travel time/ highway conditions likeness.... potential aspects - text messages when storms are going to hit certain location API's google maps geolocator weather

LIRI is a Language Interpretation and Recognition Interface. LIRI is a command line Node.js app that takes in parameters and passes back data based on those parameters.
In this assignment, you'll use the GIPHY API to make a dynamic web page that populates with gifs of your choice.
This application implements a simple command line based storefront using the npm inquirer package and the MySQL database backend together with the npm mysql package. The application presents an interface for a customer.


Market capitalization relates to the complete market value of the stocks of a company in the intrinsic value of say, a US Dollar. Commonly known as "market cap," it is calculated by multiplying the separate stocks of a company by one share's present market price. As compared to using revenues or complete asset numbers, the business group utilizes this figure to determine the size and power of a company.
Using market capitalization to demonstrate a company's size is essential because the size of a firm is fundamental to multiple features that interest customers, including risks and dividends.
The market value of the equity of a company is the complete capitalization provided to a company by the investment public. Multiply the present market price of a company's inventory by the complete amount of outstanding stocks to calculate this market value.
The number of outstanding shares is listed in the equity section of the balance sheet of a company. This calculation should apply to all outstanding inventory categories, such as prevalent stock and all favored inventory categories.
So, if a business has two million outstanding common shares and its current inventory trades at $30, then its equity market capitalization is $60,000,000.
The word "circulation supply" refers to the number of cryptocurrency cards or tokens that are liberally accessible and floating around on the market.
The circulating inventory of a cryptocurrency can increase or decrease over time. For example, the circulating supply of Bitcoin will gradually improve until a maximum supply of 21 million coins is reached.
The mining technique, which generates new coins on average every 10 minutes, will imminently have to deal with such a gradual increase. Alternatively, in the event of coins burning themselves out, trading platforms are encouraged to remove them from the trading stock immediately.
The flowing supply relates to the publicly available coins that shouldn't be confused with the complete supply or max supply. Total supply is used to quantify the number of existing coins, i.e. the number of already issued coins minus the burned coins.
Basically, the complete stock is the amount of the flowing stock and the money tied up in the escrow. On the other hand, the maximum supply quantifies the maximum amount of coins that will ever exist, including the future coins that will be mined or made available.
In addition, a cryptocurrency's running stock can be used to calculate its market capitalization, produced by multiplying the present market price by the amount of coins in circulation. So if some cryptocurrency has a circulating supply of 1,000,000 coins traded at $10 each, the market cap would be $10,000,000.
Seems like a similar concept to the market capitalization? Well, it is.
Firstly, it enables shareholders to comprehend one company's relative size versus another. Market cap measures what a business is worth on the open market, as well as the perception of the market's potential opportunities because it represents what shareholders are prepared to pay for their inventory. They are often dominant competitors in developed sectors, and a domestic customer public may be acquainted with their brand names.
Secondly, mid-cap businesses are typically between $2 billion and $10 billion in market value. These are typically founded firms in sectors that are undergoing or anticipated to grow rapidly. These medium-sized enterprises may be in the phase of growing market share and general competitiveness improvement. This development phase is probable to determine whether a business will ultimately live up to its complete capacity.
Thirdly, small-cap businesses typically range from $300 million to $2 billion in market value. These are generally youthful firms serving niche markets or developing sectors.
Lower supply can imply increased demand, leading to greater rates. They also claim that this sets crypto aside from the worldwide economic scheme, whereby key banks can efficiently store more cash through a policy known as monetary adjustment, which can contribute to inflation, meaning that the currency in your pocket is not worth as much as it once was.
But some critics contend that fixed deliveries effectively prevent individuals from expenditure in terms of cryptocurrencies attaining widespread acceptance, implying that digital assets are speculative investments that individuals hoard.
When an asset is limited, depreciation is inevitable, and this generates a risk for crypto holders waiting to make their products cheaper. Inflation is something that discourages customers from holding onto their money when it comes to standard currencies— the longer it's in their purse, the less buying capacity it has.
While market cap is a useful metric for guessing how important a cryptocurrency is, several other variables must be taken into consideration. If you're searching to invest, remember that price cap is just one of the many instruments out there. You should study the initiatives you are interested in carefully and ask around to get a complete understanding of their opportunities for development. It will only get you so far to know their market cap.

[dscrdeql] <AndronicusBass-Founder> Best to keep funds in wallet and never on exchanges. I still think BarterDEX will be word of the year in the coming years. Evereryone will be sick of centralised exchanges which defeat the purpose of decentralisation. mark my word's
[dscrdeql] <Combat Wombat> yeah better to keep funds in wallet but what about when setting buy/sell orders or trading.. makes it impossible to do that
[dscrdeql] <Combat Wombat> and i still think we need a trusted centralised place
[dscrdeql] <Combat Wombat> especially if we want mass adoption
[dscrdeql] <Combat Wombat> majority of the population are not willing to be their own banks
[dscrdeql] <Combat Wombat> hopefully BarterDEX becomes easy to use because at the moment I can't get it to work lol
[dscrdeql] <Combat Wombat> but yeah i think barterDex will eventually become easy to use.. if not them some one else will make something.. a user friendly dex is def needed
[dscrdeql] <Combat Wombat> lucky i only had a little bit of spare change on cryptopia
[dscrdeql] <Combat Wombat> still hoping for the best possible result but doesn't look too good at the moment
[dscrdeql] <Combat Wombat> got a few coins that are only really traded on there
[dscrdeql] <AndronicusBass-Founder> Only expose what you are willing to lose. Unfortunately I think there is much to learn for everybody and the media is winning the Psy-op battle to deter broader awareness of an alternative from the current system. It's a battle that's for sure. Sad markets don't mean a finished market. I havent had an antenna connection to my TV for several years.
[dscrdeql] <Combat Wombat> I love computers and am sick and tired of wallets
[dscrdeql] <AndronicusBass-Founder> I programme myself, I dont let TV programme me
[dscrdeql] <Combat Wombat> the average person who doesn't really like computer won't be willing to do what we do]
[dscrdeql] <Combat Wombat> which is why we need a centralised place
[dscrdeql] <Combat Wombat> we can hate banks all we want.. and yes they are crooks but they protect what we put in there
[dscrdeql] <Combat Wombat> a friend of mine was getting billed from uber for about 4 months lol he didn't know some one was using his bank account
[dscrdeql] <Combat Wombat> but the bank paid him back
[dscrdeql] <Combat Wombat> because he could prove it wasn't him.. they were interstate transactions
[dscrdeql] <AndronicusBass-Founder> I saw a video months ago of CLI of decentralised binance. I havent looked into it yet and not sure if they have a gui yet.
[dscrdeql] <Combat Wombat> uber eats some one was ordering food daily lol he didn't even realise for 4 months man i know if 20 dollars goes missing hahaha
[dscrdeql] <Combat Wombat> yeah i remember hearing about that
[dscrdeql] <Combat Wombat> i like binance
[dscrdeql] <Combat Wombat> wish them all the success
[dscrdeql] <Combat Wombat> i think something like Binance could help spread mainstream adoption
[dscrdeql] <Combat Wombat> and with the amounts they charge for a listing they better have good security haha
[dscrdeql] <Combat Wombat> which reminds me i got coins on binance
[dscrdeql] <Combat Wombat> icon, neo and vet never used any of the wallets
[dscrdeql] <Combat Wombat> looks like its time to learn lol
[dscrdeql] <Jellysmash> I was wondering why cryptopia had been in unscheduled maintenance for the last day or so...I assumed they must of got hacked but didn't know details.
[dscrdeql] <Combat Wombat> hey jelly
[dscrdeql] <Combat Wombat> yeah sucks huh
[dscrdeql] <Combat Wombat> lets hope its not as bad as most of us are thinking but apparently a shit load of eth was withdrawn
[dscrdeql] <Jellysmash> I've only got a small amount on there. Btc sms some shitcoins.

Cartograms are maps in which the areas of regions (e.g. states, provinces) are rescaled to be proportional to statistical data (e.g. population size, gross domestic product). Cartograms are called “contiguous” if they maintain the topology of the conventional map (ie. regions are displayed as neighbours on the cartogram if and only If they are geographic neighbours) [1].
Creating such cartograms has traditionally been a complex endeavour, one that usually only academics and experts attempt and explore. However, producing contiguous cartograms should not be the privilege of only a handful of experts in cartography. Journalists or bloggers, for example, may also benefit from a cartogram as an intriguing illustration of their own data. Similarly, high school students may enrich a term paper with a cartogram that can summarize data more e ectively than raw numeric tables.
Until now, the creation of contiguous cartograms has been far from user-friendly, requiring computer skills that even experts in data visualization typically do not possess. In the past, publications that introduced new cartogram algorithms rarely included computer code. Some authors of more recent publications have posted their code online [1,2], but their software usually requires technical knowledge (e.g. about shell scripting, compiling, GIS) that pose insurmountable obstacles for most users. This is where go-cart.io comes in. With an interface that is easy for even non-experts to use, go-cart.io eliminates hurdles and provides a convenient way to create readable cartograms.
While previous cartogram generators required users to install software (e.g. Java) on their computer, go-cart.io is based on JavaScript that can be run in any contemporary web browser without additional downloads. We decided to simplify the data input as much as possible. We have curated a “library” of topologies so that users do not need GIS expertise to create geospatial vector data. After data are transmitted, a remote server calculates the cartogram transformation with the recently developed fast flow-based algorithm [1]. Because the calculation is entirely server- side, we eliminate any dependence on the client’s hardware. For typical input, the calculation finishes within 10 to 15 seconds. If the calculation needs substantially longer, the application displays a bar chart instead of a cartogram as a fallback. The cartogram is displayed in the browser window side by side with the conventional (i.e. equal-area) map. The user can explore both maps with various interactive features implemented using the D3.js library [3].

Orm
Orm is short for Object
Relational Mapper which does 2 things: it maps your database table rows to objects and it allows you
to esteblish relations between those objects.
It follows closely the
Active Record Pattern, but was also influenced by other systems.
Observers
An event based system to allow you to add behavior to specific events. When an event is observed the Orm will automaticly call all the added observers to see if there's anything for them to do.
Adding observers to your model
You can add observers in 2 ways: just add the name to have the observer called for all events or with
the observer as name and an array of specific events for which the observer is called.
When the Observer is in the same namespace as the Model and prefixed with Observer_ you can
leave out the "Observer_" prefix. In all other cases you have to provide the full classname.
class Model_Article {
protected static $_observers = array(
'example', // will call Observer_Example class for all events
'Orm\\Observer_CreatedOn' => array('before_insert'), // will only call Orm\Observer_CreatedOn at before_insert event
);
}
Included observers
Observer_CreatedAt
This observer acts only upon before_insert and expects your model to have a created_at property which will be set to the Unix timestamp when saving for the first time.
// Just add the Observer
protected static $_observers = array('Orm\\Observer_CreatedAt');
// But adding it just for before_insert is enough
protected static $_observers = array('Orm\\Observer_CreatedAt' => array('before_insert'));
You can change the default property expected and use a mySQL timestamp instead of the defaults:
// Use mySQL timestamp instead of Unix timestamp
Orm\Observer_CreatedAt::$mysql_timestamp = true;
// Use property called just "updated" instead of "updated_at"
Orm\Observer_CreatedAt::$property = 'updated';
Observer_UpdatedAt
This observer acts only upon before_save and expects your model to have a updated_at property which will be set to the Unix timestamp when saving (also during the first time).
// Just add the Observer
protected static $_observers = array('Orm\\Observer_UpdatedAt');
// But adding it just for before_insert is enough
protected static $_observers = array('Orm\\Observer_UpdatedAt' => array('before_save'));
You can change a $mysql_timestamp and $property value on this observer just like on the CreatedAt observer.
Observer_Validation
To be written.
// Just add the Observer
protected static $_observers = array('Orm\\Observer_Validation');
// But adding it just for before_insert is enough
protected static $_observers = array('Orm\\Observer_Validation' => array('before_save'));
Observer_Typing
To be written.
// Just add the Observer
protected static $_observers = array('Orm\\Observer_Typing');
// But adding it just for these specific events is enough
protected static $_observers = array('Orm\\Observer_Typing' => array('before_save', 'after_save', 'after_load'));
Creating your own Observers
You can add any class as an observer by adding the full classname (namespace included) to the Observers property of your model. There's 2 ways of creating classes that can be used as observers:
Extend the Orm\Observer class
Create a new class that extends Orm\Observer and create methods for the events upon which you want your Observer to act. In the example below you want it to act upon after_insert. The method will be passed the Model instance it is acting upon.
class Observer_Something extends Orm\Observer {
public function after_insert(Model $model)
{
\Log::info('Succesfully created new object of class '.get_class($model));
}
}
Extensions of the type Orm\Observer are singletons by default, as such you can't use a method instance() or property $_instance or it won't work anymore. Because of this methods may be both static or non-static.
Have an orm_notify() method
When you extend the Orm\Observer class it inherits an orm_notify() method that will check if there's a method that matches the event and call it when possible. But you can use any class as an observer as long as it has an orm_notify() method. That will be called on events and be passed the event name and a Model instance.
class Some_Other_Class {
// it may have many methods and properties before or after the orm_notify method
public static function orm_notify(Model $model, $event)
{
\Log::info('I was notified of the event '.$event.' on a Model of class '.get_class($model));
}
}
Event names
- after_create, called by the __construct() method once the object was created
- after_load, called by the __construct() method once an object was loaded from the database
- before_save, called by the save() method before anything is done
- after_save, called by the save() method after it has completed
- before_insert, called when an object is first saved to the database
- after_insert, called after an object is first saved to the database
- before_update, called when an object is saved to the database (except for the first time)
- after_update, called after an object is saved to the database (except for the first time)
- before_delete, called when you delete an object from the database
- after_delete, called after you delete an object from the database
- after_clone, called after an object was succesfully cloned


AgriSA Report: At least R600 Million Needed To Help Drought-Stricken Farmers
by NT EditorSevere cash flow problems and depleted animal feed reserves are now characterising the Northern Cape’s lingering drought.
AgriSA recently released its latest agriculture drought report which takes a look at the overall drought situation across the country.
As a temporary solution, experts said that at least R600 million over the next three months was needed to assist farmers.
At least 15,500 farms spanning over 27 million hectares were gripped by severe drought conditions across the province.
Head of the organisation’s disaster management centre, Willem Symington, said the sector employed around 33,000 workers, with many of these jobs now being threatened as a result of the drought.
“The effects are not great. In the short term, local economies need to be supported.”
Symington stressed that more should be done politically to drive relief interventions.
“On a political level, it seems like we’re struggling to get some action or attention in the province on this problem.”
The government earlier this year granted R30 million towards drought relief.

GROUP WORK
During this assignment we all six students in FabLab Frosinone Officine Giardino had the opportunity to work together. I find it very useful because in my experience as FabLab Roma Makers project manager I could see how difficult is for a lot of makers working together.
At beginning my duty was coordinating the group during the organization phase, in which we decided kind of machine to realize and we share the several tasks to be accomplished.
After a couple of days during which we studied and analyzed a lot of machines and the Gestalt system, we choose to build a styrofoam 3 axes machine, even respecting the idea that FabLab Frosinone had not yet a machine like this.
The six tasks we found out are:
I was assigned to the last one, but indeed we agree that each of us had to lead his task, taking part into all of them and collaborating with the other students.
WEB INTERFACE
To realize the web interface I used html5.
Massimiliano Di Bitonto and me studied the communication system of Gestalt, that uses as commands of the nodes a series of functions called by a local address.
It means that you can target the function you need by a browser, addressing to “http://<IP_ADDRESS>:27272/“ where 27272 is a defined local port.
The commands we use are:
I projected 3 graphical elements, the HEADER, introducing our FabLab and the machine, the BODY, with the control panel based on an embedded png representing the x,y,z scheme, and the FOOTER, linking to the Gestalt project.
For the control panel I projected 3 structural elements, a responsive area for the axes control, responsive buttons for the general control and a response frame to which target the sent addresses.
To realize the responsive area I drew a square representing the 3 axes and 3 home (global, x and y,z), then I embedded the png converting it in a base 64 text line using this convertor.
In this way you could upload and use this interface on a controller without file system too.
Using “map" and “area" functions, each area was transformed in a button referring to the correct command address. Adding the target to the response frame allows the interface to call the address page without leaving.
To realize the responsive buttons I assigned a style to the button function and then I inserted it in a simple targeted referral link. To upload a file, according with Massimiliano, I used two “input" function, "file type" to select it and "submit type" to upload, inserted in a "post type form" linked to a .php file realized by himself. The "file type input" has a preassigned style that I modified inserting it in a label after calling it off with the command “style=display:none;”.
At the end, during the last sunday in which we completed the machine, I doubled the “z” value in the command addresses adding a fourth value, because we used two motors to control the z axis.
Here’s the html file .


Based on your Stackoverflow post we detected that your code might be SQL injectable. We used a ran a Machine Learning model on your stackoverflow post that told us that your code might be SQL injectable. If you want to know about how to stop SQL injections, continue reading this article.
SQL injection is a web security vulnerability that allows an attacker to interfere with the queries that an application makes to its database. It allows the person executing the attack to access information that they normally should not be able to access. In some cases it can allow the attacker to delete, tamper with the contents of your database or even delete the whole database altogether!
SELECT * FROM users WHERE username = 'janedoe' AND password = 'origami123'
The attacker can provide an input for username like "'janedoe' OR 1=1 --" and any password text such that the application would have to run the following
command
SELECT * FROM users WHERE username = 'janedoe' OR 1=1 -- AND password = "random-text-here"
This command would retrieve every user and password in your database and allow access for that to the attacker. Since everything in the
same like after -- in treated as a comment no error would occur.
The attacker could also give a username like "'janedoe'; DROP table; --" and a random password again and in some cases they might be
able to delete your whole table of users. This is because the script would look like this.
SELECT * FROM users WHERE username = 'janedoe'; DROP table; -- AND password = "random-text-here"
If the attacker manages to find what your database table name is for your application they can run this script right here and replace
table with your database table names and delete the tables as well as everything in them.
Prepared statements allow the server to know what the script looks like in advance such that it knows to interpret input as as input and not as part of the script. Click here to learn how to write prepared statements.
Sanitizing the input is an extra layer that could help make sure that the user doesn't try to use keywords or invalid charaters in order to try to SQL inject the database. This is not 100% effective and must be used with other methods of preventing SQL Injections such as using prepared statements. However it is good practice to make sure that you sanitize inputs so as to help prevent SQL Injections.
To learn more about SQL Injections and how to prevent them refer to the list of resources below as a starting point.


Canvas
public final class Canvas
Canvas
provides an interface for drawing, and how the drawing is clipped and transformed.
Canvas
contains a stack of Matrix
and clip values.
Canvas
and Paint
together provide the state to draw into Surface
or BaseDevice
.
Each Canvas
draw call transforms the geometry of the object by the concatenation of all
Matrix
values in the stack. The transformed geometry is clipped by the intersection
of all of clip values in the stack. The Canvas
draw calls use Paint
to supply drawing
state such as color, Typeface
, text size, stroke width, Shader
and so on.
To draw to a pixel-based destination, create raster surface or GPU surface.
Request Canvas
from Surface
to obtain the interface to draw.
Canvas
generated by raster surface draws to memory visible to the CPU.
Canvas
generated by GPU surface uses Vulkan or OpenGL to draw to the GPU.
To draw to a document, obtain Canvas
from SVG canvas, document PDF, or PictureRecorder
.
Document
based Canvas
and other Canvas
subclasses reference BaseDevice
describing the
destination.
Typically you create the Canvas from a bitmap, but an empty canvas can be created with the
some fo the static make
methods, and serve special purposes:
makeEmpty(width:height)
- creates an empty canvas that ignores all drawing commandsmakeOverdraw(canvas:)
- A canvas that captures all drawing commands, and rather than draw the actual content, it increments the alpha channel of each pixel every time it would have been touched by a draw call.makeNway(width:height:)
- will create a passthrough n-way canvas. Once created you can add canvas withaddCanvas
