VALUES ( expression [, ...] ) [, ...] [ ORDER BY sort_expression [ ASC | DESC | USING operator ] [, ...] ] [ LIMIT { count | ALL } ] [ OFFSET start [ ROW | ROWS ] ] [ FETCH { FIRST | NEXT } [ count ] { ROW | ROWS } ONLY ]
VALUES computes a row value or set of row values specified by value expressions. It is most commonly used to generate a "constant table" within a larger command, but it can be used on its own.
When more than one row is specified, all the rows must have the same number of elements. The data types of the resulting table's columns are determined by combining the explicit or inferred types of the expressions appearing in that column, using the same rules as for UNION (see Section 10.5).
Within larger commands, VALUES is syntactically allowed anywhere that SELECT is. Because it is treated like a SELECT by the grammar, it is possible to use the ORDER BY, LIMIT (or equivalently FETCH FIRST), and OFFSET clauses with a VALUES command.
A constant or expression to compute and insert at the indicated place in the resulting table (set of rows). In a VALUES list appearing at the top level of an INSERT, an expression can be replaced by DEFAULT to indicate that the destination column's default value should be inserted. DEFAULT cannot be used when VALUES appears in other contexts.
An expression or integer constant indicating how to sort the result rows. This expression can refer to the columns of the VALUES result as column1, column2, etc. For more details see ORDER BY Clause.
A sorting operator. For details see ORDER BY Clause.
The maximum number of rows to return. For details see LIMIT Clause.
The number of rows to skip before starting to return rows. For details see LIMIT Clause.
VALUES lists with very large numbers of rows should be avoided, as you might encounter out-of-memory failures or poor performance. VALUES appearing within INSERT is a special case (because the desired column types are known from the INSERT's target table, and need not be inferred by scanning the VALUES list), so it can handle larger lists than are practical in other contexts.
A bare VALUES command:
VALUES (1, 'one'), (2, 'two'), (3, 'three');
This will return a table of two columns and three rows.  The most common use is in INSERT:
INSERT INTO films (code, title, did, date_prod, kind) VALUES ('T_601', 'Yojimbo', 106, '1961-06-16', 'Drama');
In the context of INSERT, entries of a VALUES list can be DEFAULT to indicate that the column default should be used here instead of specifying a value:
INSERT INTO films VALUES ('UA502', 'Bananas', 105, DEFAULT, 'Comedy', '82 minutes'), ('T_601', 'Yojimbo', 106, DEFAULT, 'Drama', DEFAULT);
VALUES can also be used where a sub-SELECT might be written, for example in a FROM clause:
SELECT f.* FROM films f, (VALUES('MGM', 'Horror'), ('UA', 'Sci-Fi')) AS t (studio, kind) WHERE f.studio = t.studio AND f.kind = t.kind; UPDATE employees SET salary = salary * v.increase FROM (VALUES(1, 200000, 1.2), (2, 400000, 1.4)) AS v (depno, target, increase) WHERE employees.depno = v.depno AND employees.sales >= v.target;
Note that an AS clause is required when VALUES is used in a FROM clause, just as is true for SELECT. It is not required that the AS clause specify names for all the columns, but it's good practice to do so. (The default column names for VALUES are column1, column2, etc in PostgreSQL, but these names might be different in other database systems.)
When VALUES is used in INSERT, the values are all automatically coerced to the data type of the corresponding destination column. When it's used in other contexts, it might be necessary to specify the correct data type. If the entries are all quoted literal constants, coercing the first is sufficient to determine the assumed type for all:
SELECT * FROM machines WHERE ip_address IN (VALUES('<IP_ADDRESS>'::inet), ('<IP_ADDRESS>'), ('<IP_ADDRESS>'));
Tip: For simple IN tests, it's better to rely on the list-of-scalars form of IN than to write a VALUES query as shown above. The list of scalars method requires less writing and is often more efficient.
VALUES conforms to the SQL standard. LIMIT and OFFSET are PostgreSQL extensions; see also under SELECT.

iSensor-SPI-Buffer global register array (read-able via SPI). Global scope
| void BufDequeueToOutputRegs | ( | ) |
Dequeues an entry from the buffer and loads it to the primary output registers.
This function is called from the main loop to preserve SPI responsiveness while a buffer entry is being dequeued into the output registers. This allows a user to read the buffer contents while the values are being moved (if they start reading at buffer entry 0). After moving all values to the correct location in the output register array, the function sets up the burst read DMA (if enabled in user SPI config).
| void ButtonPressHandler | ( | ) |
Handler for when a button is pressed.
This function executes commands based on the button configuration set in BTN_CONFIG. This function can be called from an interrupt context (EXTI rising edge interrupt for button). The EXTI pending interrupt register for the button line should be cleared before and after executing this function to add some implicit debouncing (interrupt won't trigger, then immediately trigger again).
| void FactoryReset | ( | ) |
Load factory default values for all registers, and applies any settings changes.
This is accomplished in "lazy" manner via #define for each register default value (defaults are stored in program memory, storage is managed by compiler). This function only changes values in SRAM, does not change flash contents (registers will reset on next re-boot).
| void GetBuildDate | ( | ) |
Populates the firmware date registers automatically.
Registers are populated by parsing the DATE macro result, which is set at compile time
| void GetSN | ( | ) |
Populates the six SN registers automatically.
The SN registers are populated from the 96-bit unique ID (UID)
| void ProcessCommand | ( | ) |
Processes a command register write. This function is called from main loop.
Only one command can be executed per write to the USER_COMMAND register. Command execution priority is determined by the order in which the command flags are checked.
|
static |
Process a write to the iSensor-SPI-Buffer registers.
This function handles filtering for read-only registers. It also handles setting the deferred processing flags as needed for any config/command register writes. This are processed on the next pass of the main loop.
| uint16_t ReadReg | ( | uint8_t | regAddr | ) |
Process a register read request (from master)
| regAddr | The byte address of the register to read |
For selected pages not addressed by iSensor-SPI-Buffer, the read is passed through to the connected IMU, using the spi_passthrough module. If the selected page is [253 - 255] this read request is processed directly.
| uint16_t WriteReg | ( | uint8_t | regAddr, |
| uint8_t | regValue | ||
| ) |
Process a register write request (from master)
| regAddr | The address of the register to write to |
| regValue | The value to write to the register |
For selected pages not addressed by iSensor-SPI-Buffer, the write is passed through to the connected IMU, using the spi_passthrough module. If the selected page is [253 - 255] this write request is processed directly. The firmware echoes back the processed write value so that the master can verify the write contents on the next SPI transaction.

I notice a lot of movie reviewers talk about how CG is overused in movies, and while that may be true, they also say it looks obvious whether CG or actual props are being used. Maybe it's because I don't have a 16ft by 9ft screen, but I honestly have never been able to tell the difference without someone telling me. Is it really that noticeable?
CGI* =D
And also I think it really depends on what the image is, if you take something like star-wars laser blasters than yeah it's pretty obvious, but certain characters in modern films could be actors in makeup or could be completely generated and sometimes I can't tell the difference
If you notice it then then you know that you have seen it.
If you don't notice it then you don't know that you have seen it.
If you don't know you have seen it, you think it wasn't there.
This distorts your perception of how good it it.
IMO, CGI is a crutch that is overused. Not because the effect itself is bad or played out... but because it makes it really easy to make visually appealing movies that are otherwise empty.
Acting, writing, story, etc all become less important when you have good CGI. And good CGI is everywhere now... which is partially why modern movies really, really suck. Nobody is interested in creating substance anymore. As long as there's flashy explosions and cool effects, suckers will keep buying movie tickets.
See: any Michael Bay movie and any comic book movie... which comprise 95% of movies that have come out in the past 7 years.
^+1 Disch
This is why I watch anime, even though they're entirely CGI they're nice simple art style and focus highly on story (well the decent ones do)
It looked like it was copy/pasted onto his face. (Look near his brow if you can't spot it, it's more noticeable there)
EDIT: Though you can spot it with the motion too. If you keep an eye on the edges of the mask when he's moving his face around, the mask doesn't quite move the same as the rest of his face does.

I saw this article on HBR (it is from last year). It is meant for “nice people”, but I think these are just as applicable to Product Managers, who often need to wield influence without authority.
Teams need conflict to function effectively. Conflict allows the team to come to terms with difficult situations, to synthesize diverse perspectives, and to make sure solutions are well thought-out. Conflict is uncomfortable, but it is the source of true innovation and also a critical process in identifying and mitigating risks.
As a PM, you need to be comfortable with a healthy level of conflict. Healthy Conflict is a sign of passionate people who stand for something. If you are not getting push back on your ideas, you may be settling for mediocre local maxima.
The secret of having healthy conflict and maintaining your self-image as a nice person is all in the mindset and the delivery. To start shifting your mindset, think about your value to the team not in how often you agree, but in how often you add unique value.
Wow! and now for a couple of specific tips:
- Use “and,” not “but.”
May Sound cheesy, but this is a flavor of the Yes And Principle in Improv.
- Ask for help. Another tactic for “nice conflict” is to be mildly self-deprecating and to own the misunderstanding.
The wrong way to be a hero is by avoiding conflict or “taking one for the team”. Don’t be that kind of a heroic PM.


--- title: Taylor Approximation and JAX author: Cristóbal Alcázar date: '2022-01-28' draft: false toc: true slug: [] categories: [JAX, AUTODIFF, PYTHON, MML, CALCULUS] tags: [MML, CALCULUS, JAX] comments: no showcomments: yes showpagemeta: yes ---
TL;DR: In this post, we reviewed the concept of Taylor approximation, focusing on differentiating using automatic differentiation techniques implemented in the python JAX library. Taylor approximation is a powerful tool for analyzing non-linear systems such as neural networks. We will examine two examples distilling from the book Mathematics for Machine Learning, chapter 5, and implement code to have the ability to reproduce and extend a quadratic approximation for other functions.
Taylor’s series allows us to approximate a function 𝑓 as a polynomial, computed using derivatives. In the extrema, if we used infinite coefficients, or up to times that 𝑓 can differentiate, we ended up with a perfect approximation.
\[T_n(x):=\sum_{k=0}^{n}\frac{f^{(k)}(x_0)}{k!}(x-x_0)^k\]
\[T_1(x):= f(x_0) + f^{(1)}(x_0)(x-x_0)\]
Note: 𝑓(𝑘) is 𝑓 differentiate k times, and 𝑘=0 is 𝑓 itself.
Let’s code an example; I will replicate figure 5.4 from the Mathematics for Machine Learning book.
We want to approximate the following function around \(x=0\):
\[f(x) = sin(x) + cos(x)\]
def fun(x):
return np.sin(x) + np.cos(x)
That is like \(f\) looks like around \(x=0\) The task is to get an expression that describes how \(f\) varies around the \(x=0\) neighbourhood. The most straightforward way to achieve this is to remember that \(f'(x)\) is another function that gives us the tangent line at point \(x\). We finish our task; we get an approximation of \(f\) just giving the equation of the tangent line at 𝑥. Knowing what’s the derivative of \(sin\) and \(cos\) plus the addition rule for differentiating, we can compute this manually:
\[f'(x)=cos(x)-sin(x)\]
# Evaluating f`at x=0
np.cos(0) - np.sin(0)
> 1.0
And we get the equation for the tangent line approximating at \(x_0=0\), \(y=f(0)=1\), and \(m=f'(x_0=0)=1\):
\[y - y_0 = m (x - x_0)\]
\[y = 1 + f'(x_0)x\]
\[y = 1 + x\]
taylor_approx(fun, approx_around = 0.0, num_coef=2)
Notice that the tangent line is a pretty good approximation in the immediate space around \(x=0\), but we want something that goes beyond our block. Our approximation gets higher errors when we cross the street at the corner (look at \(x=2\)!).
If we want to be famous at a scale, we need to improve our approximation. To do that, we can improve how we deal with the curvature.
taylor_approx(fun, approx_around = 0.0, num_coef=3, PLOT_COEF = (0,1,2))
The green line does a better job approximating \(f\) within -1 and 1 than the line. It was intuitive to get an expression for the tangent line, not a quadratic one. How do we get the equation that describes the green line?
Here is when Taylor’s polynomial series is pretty handy:
\[T_2(x):=\sum_{k=0}^{2}\frac{f^{(k)}(x_0)}{k!}(x-x_0)^k\]
To our line equation, we need to add the last term describes in \(T_2\). To obtain this term, we need to compute \(f''\).
In this case, the second derivative is easily computable given that the derivatives are also cyclical because of the nature of \(sin\) and \(cos\):
\(f''=\frac{\partial^2f}{\partial x^2}=\frac{\partial^2}{\partial x^2}\big(sin(x) + cos(x)\big)\)
\(f''=-sin(x)-cos(x)\)
The quadratic approximation or the second-order Taylor approximation is:
\[T_2(x) = 1 + x + \frac{f''(x_0)}{2}x^2\]
# Evaluating f'' at x=0
-np.sin(0) - np.cos(0)
> -1.0
\[T_2(x) = 1 + x -\frac{1}{2}x^2\] It makes sense with the above pictures because the coefficient accompanied by the quadratic term is negative, and therefore we have a concave down curve. Like you can see.
plt.plot(x_jnp, 1 + x_jnp - 0.5 * x_jnp ** 2,
color='forestgreen',
linestyle='-')
So we can continue repeating this process, adding more coefficients and getting a more accurate approximation. Of course, at the cost of computing higher-order derivatives.
The below image is the final reproduction of figure 5.4. Notice the power of 10 Taylor coefficients (red curve); it approximate \(f\) within the domain interval -4 and 4 almost perfectly. Be cautious, the same that happens with the fifth-order Taylor approximation (green curve), which distances from \(f\) in both lateral of the plot; it would happen to \(T_{10}\) if we expand the x-domain region in the plot.
taylor_approx(fun, approx_around = 0.0, num_coef=11)
Some thoughts about this section.
How can we differentiate any 𝑓 no matter its complexity without relying on manual computations?
How can we express the differentiation operations in code?
How can we extend Taylor approximation to multivariate functions (i.e. \(f(x_1, \dots, x_n)\)) and everything which involve gradients?
JAX is a python library that
combines the numpy
’s interface, automatic differentiation capabilities, and
high-performance operations using XLA and GPU operations.
In this section, we will focus on the fundamentals of JAX to illustrate how to perform automatic differentiation and understand how JAX operates at a high level.
jax.grad()
: given a function \(f(x)\) implemented in code, it returns a function
for compute the gradient (\(f'(x)\))jax.vmap()
: vectorize a jax.grad
’s functionjax.jit()
: accelerate a function computations using XLALet’s start with an example used by the autograd
library, the predecessor of JAX
: differentiate the hyperbolic tangent function.
The example is very illustrative because it is apparent how
jax.grad
works modifying functions; look at the code!
from jax import grad, vmap, jit
@jax.jit
def tanh(x):
return (1.0 - jnp.exp(-x)) / (1.0 + jnp.exp(-x))
x = jnp.linspace(-7, 7, 200)
fig, ax = plt.subplots(1, 2, sharey=True, figsize=(12.5, 4.5))
ax[0].plot(x, tanh(x), linestyle='-', color='black')
ax[0].axis('off')
ax[1].plot(x, tanh(x),
x, vmap(grad(tanh))(x), # 1st derivative
x, vmap(grad(grad(tanh)))(x), # 2nd derivative
x, vmap(grad(grad(grad(tanh))))(x), # 3rd derivative
x, vmap(grad(grad(grad(grad(tanh)))))(x), # 4th derivative
x, vmap(grad(grad(grad(grad(grad(tanh))))))(x), # 5th derivative
x, vmap(grad(grad(grad(grad(grad(grad(tanh)))))))(x)) # 6th derivative
plt.suptitle('tanh and its higher-order derivatives (up to 6th)')
fig.text(0.75, .02, "Source: Autograd README", size=9, style='italic')
ax[1].axis('off')
As you can see in the code, grad(tanh)
gives you a
function to compute the first derivative of tanh
. Therefore, the transformation
of jax.grad
in math notation is the following.
\[(\nabla f)(x)_i = \frac{\partial f}{\partial x_i}(x)\]
Another interesting point is that jax.grad
allows you to compose functions in a
series of transformations, such as the nested grad application to compute the
higher-order derivatives of tanh
.
Why is the purpose of jax.vmap
? If we want that
the function that jax.grad
returns behave like this:
tanh(jnp.array([1.0, 2.0,3.0]))
> DeviceArray([0.46211717, 0.7615941 , 0.90514827], dtype=float32)
We need to vectorize the function. Otherwise, we will have an error.
grad(tanh)(1.0)
#grad(tanh)(jnp.arange(10)) # throw an error
> DeviceArray(0.39322388, dtype=float32)
Therefore, if we want to evaluate the gradient at multiple values and receive an
array with the results, we can use jax.vmap
to transform the function into a
vectorize version as much as grad operates modifying functions.
vmap(grad(tanh))(jnp.array([1.0, 2.0, 3.0]))
> DeviceArray([0.39322388, 0.20998716, 0.09035333], dtype=float32)
We can code a naive implementation of jax.vmap
to
understand what happens behind the scene. Beware that
the original function is far more complex, but this is fair to illustrate the main functionality.
def my_vmap(x, grad):
"""A basic implementation of vmap to vectorize a function"""
FUN = grad
out = []
for i in range(x.shape[0]):
out.append(FUN(x[i]))
return jnp.array(out)
my_vmap(jnp.array([1.0, 2.0, 3.0]), grad(tanh))
> DeviceArray([0.39322388, 0.20998716, 0.09035333], dtype=float32)
You have an idea of how I replicate figure 5.4 of the previous sections that
require computing up to a tenth-order Taylor approximation. Yes, it’s unnecessary
to hand-code the derivatives. I just used jax.grad
ten times over \(f\) itself.
NABLA = FUN
for i in range(NUM):
# Compute the ith derivative of FUN
NABLA = jax.grad(NABLA)
# Do something like computing the ith taylor coefficient
...
For instance, let’s plot tanh
and its derivatives, but this time we will differentiate
ten times using the above pattern and avoid the nested code’s boilerplate.
NABLA = tanh
for i in range(10):
plt.plot(x, vmap(NABLA)(x))
NABLA = grad(NABLA)
plt.axis('off')
Computing higher-order derivatives can be computationally expensive. Read the paper “Taylor-Mode Automatic Differentiation for Higher-Order Derivatives in JAX” to understand the efficient way to compute higher-order derivatives. More context about this problem and the paper’s genesis in this discussion.
How are the derivatives computed? JAX
allow us to perform automatic differentiation and calculates results transforming numerical functions into a directed acyclic graph (DAG):
The differentiation is just an application of the chain rule over DAG.
Once we have all the derivatives, we start multiplying but wait, the order matters. Suppose we begin multiplying the square “F”, as the diagram above shows you. Using different orders to compute the gradient can get efficient depending on the problem.
jax.make_jaxpr
produces the JAX representation of the computation made, and it helps us visualise the diagram described above.
The intermediate variables are equations (jaxpr.eqns
) that receive inputs, could be the function’s input or other intermediate variables, and a set of primitive operations to compute over these to produce outputs.
You can read more about jax.make_jaxpr
in the documentation.
For instance, we can inspect how JAX decouples the function \(f(x)=x^2 + exp(x)\) in intermediate variables.
def f(x):
return x**2 + jnp.exp(x)
jax_compu = jax.make_jaxpr(f)(3.0)
jax_compu
>
{ lambda ; a:f32[]. let
b:f32[] = integer_pow[y=2] a
c:f32[] = exp a
d:f32[] = add b c
in (d,) }
We can code a function to extract each element of the above jaxpr
.
def describe_jaxpr(FUN):
"""Given a function, print each element of its jaxpr"""
from inspect import getsource
print('Source function definition:')
print(getsource(FUN))
print('--------------------------------------------------------------')
# Evaluate the expression on 0.0 (arbitrary) to get a jaxpr
expr = jax.make_jaxpr(FUN)(0.0).jaxpr

print('the function has the following constants, represented as ' + str(expr.constvars))
# Get the equation that describe each intermediate variable and extract info
print('\nThese are the intermediate variables describe by the equations computed along the DAG: ')
for i, eq in enumerate(expr.eqns):

Similar to the diagram above, we have two intermediate variables used to describe the output in this example.
Similarly, we can inspect the gradient function of \(f\) given by jax.grad(f)
:
describe_jaxpr(jax.grad(f))
>
Source function definition:
def f(x):
return x**2 + jnp.exp(x)
--------------------------------------------------------------
The function has the following inputs, represented as [a]
the function has the following constants, represented as []
These are the intermediate variables describe by the equations computed along the DAG:
0. Obtain [b] applying the primitive integer_pow with params {'y': 2} on input/s [a]
1. Obtain [c] applying the primitive integer_pow with params {'y': 1} on input/s [a]
2. Obtain [d] applying the primitive mul with params {} on input/s [2.0, c]
3. Obtain [e] applying the primitive exp with params {} on input/s [a]
4. Obtain [_] applying the primitive add with params {} on input/s [b, e]
5. Obtain [f] applying the primitive mul with params {} on input/s [1.0, e]
6. Obtain [g] applying the primitive mul with params {} on input/s [1.0, d]
7. Obtain [h] applying the primitive add_any with params {} on input/s [f, g]
The output is: [h]
Notice that the number of intermediate variables increases. For instance, you can look at the equation described in (2) that is a primitive adding resulting from the differentiation: \(\partial/\partial x (x^2)\rightarrow 2x\).
Further resources on automatic differentiation and JAX:
Now we consider the setting when functions are multivariate:
\[f: ℝ^D ⟶ ℝ\] \[\quad \quad \quad \quad \quad \quad x ↦ f(x), \quad x \in ℝ^D\]
By definition 5.8 in MML, we have that a Taylor approximation of degree n is defined as:
\[T_n(x)=\sum^{n}_{k=0}\frac{D^k_x f(x_0)}{k!} 𝜹^k\]
The vector \(𝜹\) represents a difference between \(x\) and \(x_0\); the latter is a pivot-vector in which the approximation is around made.
\(D^k_x\) and \(𝝳^k\) are tensors or k-dimensionl arrays.
If we have that \(𝛅 \in ℝ^4\), we obtain \(𝛅^2:=𝛅⨂𝛅=𝛅𝛅^T ∈ ℝ^{4x4}\)

For instance, in the last 4x4x4 array, the last number computed is 64 by
delta[3]*delta[3]*delta[3]
(4x4x4). Instead, the most lower-left element of the
third 4x4 array is 48 and you obtained it by delta[2]*delta[3]*delta[3]
(3x4x4).
The Einstein Summation implemented in jnp.einsum
is a notation that allow you to
represent a lot of array operations using index notation. Look this video for a detail explanation and the
documentation.
Let’s code the example 5.15, deriving at first manually and then use JAX to check if we reach similar results.
def g(x, y):
"""Function used in the example 5.15 in MML"""
return x ** 2 + 2 * x * y + y **3
x = jnp.linspace(-5, 5, 50)
y = jnp.linspace(-5, 5, 40)
X, Y = np.meshgrid(x, y)
Z = g(X, Y)
fig = plt.figure(figsize = (7.2, 4.3))
ax = fig.add_subplot(1, 1, 1, projection='3d')
ax.set_title("$g(x,y)=x^2+2xy+y^3$")
ax.plot_surface(X, Y, Z, rstride = 3, cstride = 3, cmap = 'cividis',
antialiased=False, alpha=.6)
ax.set_xlabel('x')
ax.set_ylabel('y')
ax.set_zlabel('z')
ax.zaxis.set_major_locator(
plt.MultipleLocator(60))
plt.subplots_adjust(left=0.0)
ax.view_init(15, 45)
We will start with the first-order Taylor approximation, which gives us a plane.
We need \(\partial g/ \partial x\) and \(\partial g/ \partial y\) collect the gradient into a vector (aka jacobian vector) and multiply by \(𝛅\).
\[\partial g/\partial x=2x+2y\] \[\partial g/ \partial y=2x+3y^2\]
Collect the partials into a vector:
\[D^1_x=\nabla_{x,y}=\big[2x+2y \quad 2x+3y^2\big]\]
Following the instruction of the example, we will approximate around \((x_0, y_0)=(1,2)\).
Now we can evaluate all the expressions for completing the equation that describes the plane:
\[T_1(x, y)=f(x_0, y_0) + \frac{D^1_x f(x_0, y_0)}{1!} 𝜹^1\]
def dg_dx(x,y):
"""Derivative of g() w.r.t x hand-coded"""
return 2*x + 2*y
def dg_dy(x,y):
"""Derivative of g() w.r.t y hand-coded"""
return 2*x + 3*y**2
print('g(1,2): ' + str(g(1,2)))
print('dg/dx(1,2): ' + str(dg_dx(1,2)))
print('dg/dx(1,2): ' + str(dg_dy(1,2)))
> g(1,2): 13
> dg/dx(1,2): 6
> dg/dx(1,2): 14
\[T_1(x, y)=13 + [6 \quad 14] \begin{bmatrix} x-1 \cr y-2 \end{bmatrix}\]
\[T_1(x, y)=13 + 6(x-1) + 14(y-2)\]
\[T_1(x, y)=6x+14y-21\]
def g_plane_approx(x, y):
"""Equation that describe the tangent plane at g(1,2)"""
return 6*x + 14*y - 21
Similar to the 1D case, but now the line is a plane. You can notice that is a good approximation at the very close neighbourhood of the point \((x_0, y_0)=(1,2)\). However, the plane fails to approximate the curvatures of \(g\).
Now with autodiff…how can we compute the jacobian vector? We can save all the
hand-coded derivatives using the function jax.grad
.
jax.asarray(jax.grad(g, argnums=(0,1))(1.0, 2.0))
> DeviceArray([ 6., 14.], dtype=float32
There is another way to get the jacobian.
jnp.asarray(jax.jacfwd(g, argnums=(0,1))(1.0, 2.0))
jax.jacfwd
’s name stands for jacobian forward and refers to the order that computes
the chain rule. We can use jax.jacrev
to obtain the same results but traverse
the graph backwards. There is no concern about which one to use in this example
because the function g is straightforward in complexity. Still, it matters when
many variables are involved, and as a result, we get different shapes of the
jacobian matrix.
jnp.asarray(jax.jacrev(g, argnums=(0,1))(1., 2.))
The argument argnums
specified which with argument differentiate the function.
We give a tuple with the only two arguments of g(x,y)
, i.e. I want the full jacobian vector that has the gradient w.r.t. argument 0 (x) and argument 1 (y).
For example, lets compute the jacobian vector for \(x^2+3y+z^2\) and evaluate the gradient \((1.0, 2.0, 2.0)\).
jnp.asarray(
jax.jacfwd(lambda x, y, z: x**2 + 3*y + z**2,
argnums=(0,1,2))(1.0, 2.0, 2.0)
)
> DeviceArray([2., 3., 4.], dtype=float32)
Note: jax.asarray
collect all the derivatives in a single flat array.
How can we go further computing the Hessian?
We compute the second-order derivatives of \(g\) and collect them into the \(H\) matrix.
\[H= \left(\begin{matrix} \frac{\partial^2 g}{\partial x^2}=2 & \frac{\partial^2 g}{\partial xy}=2 \\ \frac{\partial^2 g}{\partial yx}=2 & \frac{\partial^2 g}{\partial y^2}=6y \end{matrix} \right)\]
There are three constants except for the lower-right element of \(H\). We can compute \(H\) with two passes of jacfwd
and evaluate (1,2) to obtain the Hessian matrix.
H = jnp.asarray(jax.jacfwd(jax.jacfwd(g, argnums=(0,1)), argnums=(0,1))(1., 2.))
H
> DeviceArray([[ 2., 2.],
[ 2., 12.]], dtype=float32)
There is multiple ways to compute the second Taylor’s polynomial coefficient using the Hessian.
delta = jnp.array([1., 1.]) - jnp.array([1.0, 2.0])
jnp.trace(0.5 * H@jnp.einsum('i,j', delta, delta))
> DeviceArray(6., dtype=float32)
0.5 * jnp.einsum('ij,i,j', H, delta, delta)
> DeviceArray(6., dtype=float32)
Ok, now we will code a function to compute the Taylor approximation using the above knowledge.
def quadratic_taylor_approx(FUN, approx, around_to):
"""Compute the quadratic taylor approximation for the set of points 'approx' of a given FUN around the. point 'around_to'"""
delta = approx - around_to
# Compute the Jacobian and the linear component
J = jnp.asarray(jax.jacfwd(FUN, argnums=(0,1))(*around_to))
linear_component = J.dot(delta.T)
# Compute the Hessian and the qudractic component
H = jnp.asarray(
jax.jacfwd(
jax.jacfwd(FUN, argnums=(0,1)),
argnums=(0,1)
)(*around_to)
)
quadratic_component = 0.5 * jnp.einsum('ij, ij->i',
jnp.einsum('ij,jk->ik', delta,H),
delta)
return FUN(*around_to) + linear_component + quadratic_component
quadratic_taylor_approx(g, jnp.array([[1.0, 1.0], [1.0, 2.0], [3.0, 4.0]]), jnp.array([1.0, 2.0]))
> DeviceArray([ 5., 13., 89.], dtype=float32)
The quadratic component (aka second order derivatives) gives us a better way to approximate the curvature of \(g\).
Visually it looks ok, but we can use the closed-form expression for the quadratic
Taylor approximation around the point \((1, 2)\) to verify if the function
quadratic_taylor_approx
is doing its job.
Note: You can work out the closed-form expression from equation 5.180c in MML, and ignore the third-order partial derivatives.
\[T_2(x, y)=x^2+6y^2-12y+2xy+8\]
def g_quadratic_approx(x, y):
"""Close-form expression for the quadratic taylor approx of g() around (1, 2)"""
return x**2 + 6*y**2 - 12*y + 2*x*y + 8
# Some cases to test
print(g_quadratic_approx(1.0, 2.0))
print(g_quadratic_approx(2.0, 3.0))
print(g_quadratic_approx(4.2, 3.7))
print(g_quadratic_approx(2.8, 1.3))
print(g_quadratic_approx(10.2, 21))

The values are practically the same. There are some cases with approximation error around the thousandth.


Toronto officer who arrested, released Bruce McArthur pleads not guilty to disciplinary charges
A Toronto police officer involved in the 2016 arrest and release of serial killer Bruce McArthur has pleaded not guilty to disciplinary charges.
Lawyer Lawrence Gridin entered the plea this morning on behalf of Sgt. Paul Gauthier during a brief appearance before the Toronto police tribunal.
Gauthier is charged with insubordination and neglect of duty related to his handling of a complaint by a man who alleged McArthur tried to strangle him.
The officer was not present Wednesday. He has yet to appear before the tribunal, with his lawyer citing an undisclosed illness.
Gridin has said his client will be at the hearing to face the accusations against him when the time comes.
A notice of hearing released earlier this year alleges Gauthier did not record a video statement from the complainant or photograph his injuries within 72 hours, as required by the force’s policy on domestic violence investigations.
A date for a hearing has not yet been set, as the parties continue discussions over the disclosure of evidence.
Gridin has said the officer did nothing wrong.
McArthur pleaded guilty in January to eight counts of first-degree murder in the deaths of men with ties to Toronto’s gay village.
He was arrested in January 2018 and an internal probe related to the case began shortly afterwards.

Website Organization
site.baseurl = /computingBlog
page.title = Website Organization
page.date = 2019-10-11 00:00:00 -0400
home/ computingBlog/ 2019-10-11 Initial Post
The issue is figuring out how to organize this website.
Github Project Organization
The computingBlog project is layered on top of the root Github Pages project, gaminax.github.io.
Generating AsciiDoc Content
The Github Jekyll website generator is limited to Github Flavored Markdown. One can use another markdown format, but one then has to generate the HTML by some other means.
The AsciiDoctor/Jekyll-AsciiDoc-Quick-Start project shows how to generate asciidoc content via another website, https://travis-ci.org/, and have that website post the html to Github.
If one generates the html oneself, it can be done a file at a time. or a project at a time. Generating the html a file at a time has some advantages: one can use multiple source formats, and simply add the generated html file to the source. Large web pages with multiple subheadings are quite usable.
Fonts
The necessary fonts need to be requested in the stylesheets via Google Fonts, or stored on github.
Addendum 2019 11 17
Simple ways to organize website
- Plugins can be loaded from _config.yml, without a version number. There is no need for Ruby Gems. So no need for Gemfile or messing with bundler. The Jekyll website ought to emphasize this more.
- Build /texts and /computing offline to docs when using asciidoc plugin.
- Use IBM Plex fonts from fonts.google.com. These are a good and unified font set.
- Deriving a dark theme from minima: One can override the minima CSS coloring by adding CSS coloring to assets/css/style.scss. I initially tried copying and editing all the CSS files, but overriding is simpler. A dark theme derived from minima would be good; one would not need to add to style.scss.
- The best dark background seems to be dark green, #030, or #040. This has enough color in it to be distinguishable from black, #000.
- minima syntax highlighting: The foreground text colors of the minima theme, other than the main text color, do not seem to need to be overriden. We only need to change the background colors.


Image View¶
An Image View is displayed when an item on the Project Explorer is selected by mouse a single click on branch items or double click on sub item.
Viewing Images¶
The Image Viewer in combination with the Project Explorer allows users to view a large variety of image formats. Ref Adding Addition Image Formats on what formats are supported.
Note: In some cases viewing an image may take some time to display if the CPU is used to decompress a large compressed image item.
- To display an original image view, single mouse click on the item on the Project Explorer.
- To display a destination item image view double click mouse on the Item on the Project Explorer.
Image View of Ruby.bmp
To view a processed image (Project Explorer destination item with a green circle), double click on it (Ruby_bmp_1 in this example) and you will see another Image View tab window appear displaying the processed image.
BC7 Compressed Image View of Ruby_bmp1.dds file
Users can capture viewed images to file using context menu “Save View as” or keyboard keys Ctrl C (displayed image), Alt C (original source image) to save to Windows Clipboard.
Image view context menu (enabled by right mouse button click)
Cursor positions in block increments is also displayed, users can now save any block to file using “Save Source Block … as” where … is the current cursor location translated to a block position.
Image view status bar showing cursors block position
This feature is useful in capturing the source texture blocks that was used for generating compressed blocks that exhibit decompressed image artifacts or poor quality. Depending on the source, a 4x4 block image is saved to either BMP or EXR file formats, which can later be used for repeated analysis.
Using a Mouse Wheel for Zoom¶
Rotating the mouse wheel in or out will also zoom the image in increments of 10. To zoom at a faster rate (increments of 100) hold down the keyboard Ctrl key and rotate the mouse wheel. Zoom will be centered on the current mouse cursor location.
Using the Mouse to Move the Image in the View¶
To move the image around the view, place the mouse over the image and press down the left mouse button. While keeping it pressed, move the image around the view. To stop the move, release the left mouse button.
Note: you can only perform these operations when the mouse cursor is over the image.
Adding additional Image Formats¶
There are a number of default image file formats that are supported by the application
| Format | Description |
|---|---|
| BMP | Windows Bitmap |
| PNG | Portable Network Graphics |
| EXR | High Dynamic Range Images |
| DDS | Direct Draw Surface files |
| KTX, KTX2 | Khronos Texture Files |
| TGA | Targa Texture files |
| TIFF | Tagged Image File Format files |
Support for ASTC, EXR, TGA, DDS and KTX are linked into the main application and cannot be overwritten
Users can add additional file format by placing appropriate Qt Image plugins into \plugins\imageformats folder.
KTX2 Support Notes¶
KTX2 is supported by a DLL in the plugin folder AMD Compress\plugins\imageformats and at the root folder as ktx.dll it supports saving and loading multichannel images, BCn, ETCn, and ASTC codecs.
The following custom image formats supported in Compressonator KTX is not available in KTX2 ATC_RGB,ATC_RGBA_Explicit,ATI1N,ATI2N,ATI2N_XY, DXT5_xGBR, ATI2N_DXT5, DXT5_xGBR,DXT5_RxBG ,DXT5_RBxG,DXT5_xRBG,DXT5_RGxB and DXT5_xGxR.
For ATI1N use BC4 and for ATI2N use BC5.
Additional support for universal textures and streaming can be added upon request. For specific KTX2 feature enablement, please file a request at https://github.com/GPUOpen-Tools/compressonator/issues
Image View switch between Original and Processed¶
This feature allows users to switch quickly between Original Image View and Processed Image View (Processed refers to Compressed Image View or Pixels Difference Image View) by simple key stokes (O or P) or from the Image View bar dropdown list. This allows users to have a visual comparison between Original and Processed images.
After compressing image, click on the green circle beside the compressed Image to generate the image view window as shown below:
Click on the Image View window to set focus, then hit “Space” bar to switch between Original and Processed (In this case, Processed refers to Compressed Image) Image Views. You can also switch between Processed and and Original Views by select the related views from the combo drop down list
To change the Processed Image View to Image Diff View, click on the icon beside the , observed that Processed View now shows Image Diff View (In this case, Processed refers to Image Diff), you can switch between Original and Image Diff View by hitting the “Space” bar. Note: You may need to increase the Image Brightness by clicking on to view the Processed Image Diff.
To change the Processed Image View back to Compressed Image View, click on the same icon .
PSNR Display Feature for GUI Image Views¶
All Compressed image views in the GUI application display a PSNR value for each MIP level and cube face.
Users can log and compare the quality of the compressed images and the effects that various filter options have on mip levels after processing.


Couple who won £105 million on 25th anniversary of lottery to go public
The pair from the Chichester area will reveal their identity on Tuesday and share how the huge amount has changed their lives forever
by Amber Hicks, https://www.facebook.com/dailymirror/A couple who won the whopping £105m EuroMillions jackpot are set to go public tomorrow morning, it has been announced.
The winners - described as a hard working pair from the Chichester area - scooped the life-changing amount in the draw earlier this month.
The pair will reveal their identity in a matter of hours and share how the money has changed their lives forever.
They won £105,100,701.90 on the 25th birthday of The National Lottery’s first ever draw, which took place on 19 November.
The winning numbers were 8, 10, 15, 30, 42 and the lucky star numbers were 4, 6.
Do you know the lucky EuroMillions winner? Email<EMAIL_ADDRESS>The couple will become richer than singer Cheryl and footballer Harry Kane.
Meanwhile, six lucky Brits have won big in the EuroMilllions so far this year in what has been a highly successful year for UK punters.
Patrick and Frances Connolly, from Northern Ireland, won £114.9million on EuroMillions in the draw on New Year’s Day.
Ade Goodchild scooped £71million in March and an anonymous ticket-holder bagged £38.2million in April.
In June, a ticket-holder who chose to remain anonymous won £123million.
Last month the country’s biggest ever winner was made when an anonymous ticketholder scooped £170million.
The previous biggest winners in the UK were Colin and Chris Weir, from Largs, North Ayrshire, who won £161million in July 2011.
Last week we revealed how 'Lotto lout' Michael Carroll blew his £10milllion National Lottery win on wild booze and drug-fuelled parties, as well as brothels and demolition car derbies at his luxury property.
Now he lives in a rented flat and works £10-an-hour shifts as a coalman in Moray, Scotland- but says he's 'far happier now'.

Test 1: Navigation
Let's build a navigation for this site so we can switch between pages.
- Build an unordered list in a section on the page below with five list items inside it.
- Add a link inside each list item. The links we need are:
- Home - linking to home.html
- About - linking to about.html
- Icons - linking to icons.html
- Styleguide - linking to styleguide.html
- Gallery - linking to gallery.html
- For each link, create the corresponding .html files in the root of this folder by duplicating the template.html file and renaming it.
- Click through each link to check that they work.
- Styling:Remove the bullet points and the padding on the left hand side of the list so it's not indented.
- Style the list items so they site horizontally across the page rather than vertically.
- Give each link inside the list items padding of 15px at the top and bottom and 20px at the left and right.
- Give each link inside the list items a background colour of rebeccapurple and make the text colour white.
- Give each link inside the list items a hover state so that the background colour changes when you hover the mouse over it.
- Copy this entire new unordered list section and paste it at the top of each new page just after the body tag so that it's hanging out being navigable all around the site!

My name is Ben Fisher. I'm a freelance videographer from Pocatello, Idaho, but I live in Rexburg now. I have a drone license. I've been into video production for over 10 years now. You might wonder why I'm a computer science major then. Honestly, I'm not quite sure why, but it felt like the thing to do. Computers have always interested me, and I like to build things. So I figured I could try it out. So far it's been pretty challenging, but I also like it.
After I graduated from high school, I served a mission in Malaga Spain (the best mission in the world). I met a sister missionary there who was from Idaho Falls. I wrote her after I got home, and when she got home we started dating. We have been married for 10 months now.
Being that I love making videos, I started a little side business. It's called Fisher Digital Media. Most of my work has been making wedding videos, but I also have made commercials and similar promotional videos for people. I feel like I know my way around the Adobe video editing software like Premiere Pro and After Effects, yet I still learn something new about each one every day.
I started back around middle school with a video camera.  Before long, I started playing around with editing the videos, and around that time, YouTube was starting to be a thing. So we started making content for that. Looking back, I am almost embarassed by the videos that we made, but it was an essential learning time to get where I am today. We took a classes in high school with some more friends and became known in our school as the video guys.
I feel rewarded when I see the final product of a project that I have worked on. Seeing people's reactions is also a huge rush. That's kind of what keeps me going in the business, because the money part just wouldn't be enough.
I included two links at the top of this page. FDM Website is for Fisher Digital Media. It's a mock website I created but haven't officially launched yet. On there I have a portfolio if you have any interest in seeing what I've done. I also included a link to our YouTube channel that we uploaded videos to throughout high school. Feel free to poke around.


Function: SB-INT:SET-FLOATING-POINT-MODES¶
This function sets options controlling the floating-point hardware. If a keyword is not supplied, then the current value is preserved. Possible keywords:
:TRAPS A list of the exception conditions that should cause traps. Possible exceptions are :UNDERFLOW, :OVERFLOW, :INEXACT, :INVALID, :DIVIDE-BY-ZERO, and on the X86 :DENORMALIZED-OPERAND.
:ROUNDING-MODE The rounding mode to use when the result is not exact. Possible values are :NEAREST, :POSITIVE-INFINITY, :NEGATIVE-INFINITY and :ZERO. Setting this away from :NEAREST is liable to upset SBCL’s maths routines which depend on it.
:CURRENT-EXCEPTIONS :ACCRUED-EXCEPTIONS These arguments allow setting of the exception flags. The main use is setting the accrued exceptions to NIL to clear them.
:FAST-MODE Set the hardware’s “fast mode” flag, if any. When set, IEEE conformance or debuggability may be impaired. Some machines don’t have this feature, and some SBCL ports don’t implement it anyway – in such cases the value is always NIL.
:PRECISION (x86 only) :24-bit, :53-bit and :64-bit, for the internal precision of the mantissa.
GET-FLOATING-POINT-MODES may be used to find the floating point modes currently in effect. SAVE-LISP-AND-DIE preserves the floating point modes in effect.

"Liverpool are among the sides interested in Cakir, and they have been monitoring his progress.
"Trabzonspor value Cakir as being worth a minimum £18m, and will not sell him in January.
"An end-of-season move could however be on the cards."

Services Description
Website Design and Development: The service that we offer to small businesses, corporate organisations and individuals helping them create online presence to engage their customers positively, increase sales and also create exposure and return on investment.
Website Marketing and Social Media: After we build the website for our client, or a new client introduces us to their pre-existing site, we offer this service. As experts of the Web, we can analyze and test a website based on an established set of standards that account for the website's aesthetic value, scalability, functionality, ease-of-use, and main customer base. After an analysis has been made, we then explore and present to the client a detailed list of the most efficient Internet marketing tools and methods available to them within the constraints of their budget. This type of service is pertinent to our company given the fact that a very large percentage of our clients are on a tight budget and can only afford to take advantage of marketing efforts that are targeted directly at their desired demographic.
There are over 4,076,160 Nigerians on Facebook and over 8,000,000 on other social network. We help to promote products and services of businesses to these Nigerians on social networks.
Website Hosting and Maintenance: This service is offered for two reasons. The first reason is because they are both ongoing, continual services that we can use to establish and maintain a strong residual income. The second reason for offering these services is to allow for packaging together with other services either Utibe Servicess offers, or services an outside company can provide, hence allowing us to expand our range of small business Internet services.
ICT Training: Information and communication technology has changed the way we do business today and so many individuals without ICT skills now understand the important of acquiring these skills to position themselves for better opportunities. We will provide training in the following categories: web design/development, graphic design, desktop publishing and other professional courses like CCNA, MCSE to mention just a few.
Promotion
Buchii Services currently distributes a sales folder with all the pertinent information about our company and services. This folder includes our strong points, history, portfolio examples, and pricing packages info. It also contains facts based on the growth and popularity of the Internet for small businesses. We have also design and printed flyers about our latest training programmes and we have paid agent to help us distribute the flyers.
We currently operates and maintains a fully-functioning website that provides information about the company, plus a variety of helpful resources for small business owners which we will be constantly updating. In the next six months, we plan to produce and distribute bulk mail and flyers promoting our web development and hosting services to small businesses.
We have plans to offer a more compact version of our main sales folder in a brochure format. This brochure will be available both as a mail to interested parties and as a sales solicitation in other businesses.
Future Services
We plan to provide more services to our highly esteemed users in the nearest future. Below are brief details of the services that we would venture into.
Local Area Network Installation: These days, a quickly increasing number of small businesses are using computers as a necessary tool in the everyday operations of the company. We would like to be able to expand our current services to meet this new demand. We will handle every aspect of setting up a small business with an internal network of computers from purchasing, installing, and configuring the machines to software integration and educating the employees on proper usage and operating functions.
Intranet Setup Installation: In our plan, after developing an Internet website for outside marketing purposes, we would like to offer the service of implementing the website into the network for use in all the business day-to-day operations. This would include extensive product/service cataloging, vital employee and management information, sharing of accounting and inventory details, etc., all intended for strictly company uses.
Internet Access for Small Business: This feature would act as another residual, packageable service. We would target small businesses exclusively allowing us to provide more flexibility and affordability to our clients through discounted high volume rates, value added service packages, and much more aggressive technical support services.
Result-based Marketing: This is a service that no small business can turn down. We have plans to offer aggressive, intensified marketing services with the fees based solely on results. To achieve this, we are in the process of forming multiple partnerships and alliances with industry specific Internet websites and various other software and service-oriented companies that provide specific marketing services and tools based on results achieved. We feel as though offering this rare service will dramatically increase our portfolio of clients.
Other areas the company will like to tap into are value added services for telecom providers, provision of training facilities and training programme to small business and corporate organization, take ICT contract from organizations and individuals among others.

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

Biography
The achievement I am proudest of is certainly the speed I grew in my past job. I soon became of the Senior developers and started leading teams (one at a time) with very different backgrounds. Don't take me wrong: I love coding (check out my github), but I am passionate about leading and connecting. Today, my boldness and confidence on my capabilities/ethics are my main strengths. I am not afraid of starting on a very initial level at an ambitious company (if I think they have a good service), because I am confident that I will grow my career there (respecting hierarchy and being truthful to my colleagues). As soon as I finished my 3-year contract I went back to Germany to find my next professional challenge.
I have a bachelor in Computer Science, I joined research projects in Brazil and Germany and I read books on innovation, leadership and biographies on IT personalities (such as Alan Turing, Steve Jobs and Bill Gates), so I am looking for a work I can be proud of. I don't want to merely build software, I want to invent the future.
My profile is aligned to 3 main categories (in order of preference): Data Science, Backend/API and Frontend. I am passionate about two technologies and have wide experience with them: Python (for Data Science and Backend) and SQL/NoSQL, but I worked with many, many others (e.g, Java, R, ASP.Net, so forth) and I am always excited to learn new frameworks/technologies.
Prefered industries: IT, Financial and Environmental.

✅ One-line vertical or horizontal view filling
✅ Auto-disable translatesAutoresizingMaskIntoConstraints
✅ Automatically activate constraints
✅ NSLayoutConstraint collection mass activation/deactivation
❌ Something bad
Installation
- Install CocoaPods
Add this repo to your
Podfile
target 'Example' do # IMPORTANT: Make sure use_frameworks! is included at the top of the file use_frameworks! pod 'ClingConstraints' end

pod install
in the podfile directory from your terminalOpen up the
.xcworkspace
that CocoaPods createdDone!
Examples
Copy another View’s Attribute
// Creates and activates a constraint that makes thisView's height equal to thatView's
thisView.copy(.height, of: thatView)
Copying Constraints with Personal Space
// thisView copies thatView's height * 0.5 - 30.
thisView.copy(.height, of: thatView).withOffset(-30).withMultiplier(0.5)
Copying Multiple Constraints In-Line
// thisView copies the right, top, and left anchor constraints of that view-- in one line.
thisView.copy(.right, .top, .left, of: thatView)
Clinging Constraints Together
// thisView positions itself to the right of thatView with a spacing of 5
thisView.cling(.left, to: thatView, .right).withOffset(5)
Filling a View
// Fills a view from the top to the bottom with the given views
thisView.fill(.topToBottom, withViews: [thatView1, thatView2], spacing: 0)
What’s in the box?
Constraint Creation:
On any UIView, you can call the following functions.
Note that these all return the created constraint. If multiple constraints are created, a list of constraints are returned.
// This view copies the other view's attributes (returns list of created constraints)
copy(_: NSLayoutAttribute..., of: UIView)
// This view copies the other view's attribute
copy(_: NSLayoutAttribute, of: UIView)
// Clings the calling view's attribute to the other view's attribute.
cling(_: NSLayoutAttribute, to: UIView, _: NSLayoutAttribute)
// Fills the calling view with the given FillMethod from left to right.
// FillMethods: .leftToRight, .rightToLeft, .topToBottom, .bottomToTop
fill(_: FillMethod, withViews: [UIView], withSpacing: CGFloat, spacesInternally: Bool = true)
// Sets the height for this view
setHeight(_: CGFloat)
// Sets the width for this view
setWidth(_: CGFloat)
Constraint Property Chaining:
On any NSLayoutConstraint:
withMultiplier(_: CGFloat)
withOffset(_: CGFloat)
withPriority(_: UILayoutPriority)
withRelation(_: NSLayoutRelation)
For constraint activation and deactivation:
In any collection of constraints:
activateAllConstraints()
deactivateAllConstraints()

Uncharted’s Amy Hennig joins Skydance to make interactive stories for new streaming platforms
by Emily GeraAmy Hennig is charting new territory.
Best known for her role as the former creative director of the Uncharted series, Hennig will be joining Skydance Media to create new interactive series for “emerging streaming platforms,” the company announced today.
She will be joined by EA veteran Julian Beak, whose credits include Battlefield: Hardline and Need for Speed. They will be building a new Skydance team in the San Francisco Bay Area. Both Hennig and Beak previously worked together on Visceral Games’ unreleased Star Wars game.
So far there’s no word on what exactly these interactive projects will entail. An official statement from the team describes their work as “[d]esigned to reach gamers and non-gamers alike on emerging streaming platforms, new story-focused experiences — crafted as an interactive series — will employ state-of-the-art computer graphics to provide the visual fidelity of television and film, but with an active, lean-in experience that puts the audience in the driver’s seat.”
“Our goal is to create inviting and innovative experiences with the high production values and visual fidelity that will set the standard in this new media landscape,” adds Hennig.
Amy Hennig left EA in January.
“I have not worked at EA since January, technically, legally,” she said at the time. “I’m working independently and staying independent.
“I’m hoping to bring some people on board, I would love to have a little company of about six to eight people, 15 at the most, and do some more projects, do some VR stuff.”
