Oil news: US energy-related high yield bond spread hits highest since 2016
by Omkar GodboleThe US energy-related high yield bond spread has widened to 826 basis points, the highest level since 2016, Jeroen Blokland, Portfolio Manager for the Robeco Multi-Asset funds, Robeco ONE and Robeco Pension Return Portfolio, tweeted on Monday.
Back then, spreads had risen amid the sell-off in oil prices. The black gold had dropped below $30 in early 2016.
This time, however, the spreads are widening amid the rise in oil prices. For instance, WTI oil rose to $58.71 per barrel on Friday, representing a 15% rise on the low of $51.03 registered on Oct. 3.

Sink
is a simple example of this sort.
interface Sink<T> { flush(T t); }
writeAll()
is designed to flush all elements of the collection
coll
to the sink snk
, and return the last element
flushed.
public static <T> T writeAll(Collection<T> coll, Sink<T> snk) { T last; for (T t : coll) { last = t; snk.flush(last); } return last; } ... Sink<Object> s; Collection<String> cs; String str = writeAll(cs, s); // Illegal call.
writeAll()
is illegal, as no valid type
argument can be inferred; neither String
nor Object
are
appropriate types for T
, because the Collection
element and the Sink
element must be of the same type.
We can fix this error by modifying the signature of writeAll()
as
shown below, using a wildcard.
public static <T> T writeAll(Collection<? extends T>, Sink<T>) {...} ... String str = writeAll(cs, s); // Call is OK, but wrong return type.
Object
because T
matches the element type of s
, which
is Object
.
The solution is to use
a form of bounded wildcard we haven't seen yet: wildcards with a
lower bound. The syntax ? super T
denotes an unknown type
that is a supertype of T
(or T
itself; remember that
the supertype relation is reflexive). It is the dual of the bounded
wildcards we've been using, where we use ? extends T
to
denote an unknown type that is a subtype of T
.
public static <T> T writeAll(Collection<T> coll, Sink<? super T> snk) { ... } String str = writeAll(cs, s); // Yes!
String
, as desired.
Now let's turn to a more realistic example. A java.util.TreeSet<E>
represents a tree of elements of type E
that are
ordered. One way to construct a
TreeSet
is to pass a Comparator
object to the constructor.
That comparator will be used to sort the elements of the TreeSet
according to
a desired ordering.
TreeSet(Comparator<E> c)
Comparator
interface is essentially:
interface Comparator<T> { int compare(T fst, T snd); }
TreeSet<String>
and pass in a suitable
comparator, We need to pass it a Comparator
that can compare
String
s.
This can be done by a Comparator<String>
, but a
Comparator<Object>
will do just as well. However, we won't be able
to invoke the constructor given above on a Comparator<Object>
.
We can use a lower bounded wildcard to get the flexibility we want:
TreeSet(Comparator<? super E> c)
As a final example of using lower bounded wildcards, lets look at
the method Collections.max()
, which returns the maximal element
in a collection passed to it as an argument.
Now, in order for max()
to work, all elements of the collection
being passed in must implement Comparable
. Furthermore,
they must all be comparable to each other.
A first attempt at generifying this method signature yields:
public static <T extends Comparable<T>> T max(Collection<T> coll)
T
that is comparable
to itself, and returns an element of that type.
However, this code turns out to be too restrictive.
To see why, consider a type that is comparable to arbitrary objects:
class Foo implements Comparable<Object> { ... } Collection<Foo> cf = ... ; Collections.max(cf); // Should work.
cf
is comparable to every other element in cf
,
since every such element is a Foo
, which is comparable to any
object, and in particular to another Foo
. However, using the
signature above, we find that the call is rejected. The inferred type
must be Foo
, but Foo
does not
implement Comparable<Foo>
.
It isn't necessary that T
be comparable
to exactly itself. All that's required is that T
be comparable to
one of its supertypes. This give us:
public static <T extends Comparable<? super T>> T max(Collection<T> coll)
Collections.max()
is more involved. We return
to it in the next section,
Converting Legacy Code to Use Generics.
This reasoning applies to almost any usage of Comparable
that
is intended to work for arbitrary types:
You always want to use Comparable<? super T>
.
In general, if you have an API that only uses a type parameter T
as an argument,
its uses should take advantage of lower bounded wildcards (? super T
).
Conversely, if
the API only returns T
, you'll give your clients
more flexibility by using
upper bounded wildcards (? extends T
).
Set<?> unknownSet = new HashSet<String>(); ... /** Add an element t to a Set s. */ public static <T> void addToSet(Set<T> s, T t) { ... }
addToSet(unknownSet, "abc"); // Illegal.
Now, consider the following code:
class Collections { ... <T> public static Set<T> unmodifiableSet(Set<T> set) { ... } } ... Set<?> s = Collections.unmodifiableSet(unknownSet); // This works! Why?
unmodifiableSet()
does work for any
kind of Set
, regardless of its element type.
Because this situation arises relatively frequently, there is a special rule that allows such code under very specific circumstances in which the code can be proven to be safe. This rule, known as wildcard capture, allows the compiler to infer the unknown type of a wildcard as a type argument to a generic method.


Intro
Ever since I was young, I have had a love for writing. I love all types of writing, including poetry, creative writing, and even expository writing. Writing is something I find incredibly enjoyable because it gives me an outlet to express my creativity and to explore ways of subtly changing the meaning of a statement through the use of words. Sometimes I challenge myself to rework something I’ve written to make it shorter. When I do this, it forces me to think about the word choices I make. I have included it in my portfolio because I wanted to showcase a few of my favorite examples of my written work. Adults always think of me as a “techy” person because I still have a love for very technological things, but Language Arts is my favorite class, Enjoy.

It encouarged me to focus on the commands I was performing and the tags/code I was implementing and how it all works as opposed to the look of my website. It's useful in that it helped me (sort of) understand all the little 'magic spells' I was performing and most importantly that my page, basic html and css included, was functioning correctly and responsively.
What did you think about mediation before reading chapter 2? That it has a lot to do with being grounded and aware of your body through breathing. That breathing exercises will help with anxiety and calmness and that it is important to take some time out each day to just be.
That you can pay attention to attention itself and that meditation can have tangible, physical affects on skin conditions.
I enjoyed the passage about whether or not your eyes should be opened or closed during meditation and that the solution to this problem - 'temporal or spatial compromise' can be easily achieved.
I really loved the bit about 'the grandmother mind' - the importance of seeing and loving yourself as your grandmother does.

Scientists create "hyper-virulent" form of tuberculosis
BBC | Submitted by: unaesthetic
"A virulent form of tuberculosis was created in the laboratory by experts trying to alter its genetic structure. The mutant form of the bug multiplied more quickly, and was more lethal than its natural counterpart. Researchers from the University of California at Berkeley, US, had actually been trying to disable genes and make the bacterium less deadly. 'This is one of the very few hyper-virulent organisms ever created,' said scientist Dr Lisa Morici... They disabled [certain] genes, and expected to find a weakened form of TB as a result. Instead, the organism grew in virulence. It killed laboratory mice within seven months of exposure, while those infected with normal TB survived the experiment."

Cable installers charged in cat dragging death
Press of Atlantic City | Submitted by: optional
"Two cable installers face animal-cruelty charges after police allegedly saw a cat tethered to the bumper of a cable-company truck and being dragged along at a high rate of speed as another truck from the same company drove behind it. The Dec. 22 incident killed the adult cat and left it mutilated to the point that the animal's sex cannot be determined, police Sgt. Ken Brown said Monday... The cat was tied to the rear bumper of one truck by its neck with four feet of cable wire and one of its legs had snapped off... Authorities identified the driver of the truck that was dragging the cat as Robert Hewitt Jr., 28, of Hickory Lane in Egg Harbor Township, and the driver of the truck that was following him as Joseph M. Newton Jr., 25, of Maddox Run in Galloway Township."

Mattel is taught the meaning of "fair use"
Houston Chronicle | Submitted by: When you pry it from my dead, cold hand.
"Noting the image of Barbie dolls is 'ripe for social comment,' a three judge panel of the 9th Circuit Court of Appeals rejected toymaker Mattel Inc.'s appeal of a lower court ruling in favor of lampooning the popular doll. The San Francisco-based appeals court ruled that naked photos of Barbie made by Kanab, Utah, artist Thomas Forsythe were meant to be a parody and could not affect demand for Mattel products... Forsythe had used Barbie dolls in absurd and often sexualized positions for his 'Food Chain Barbie' photos. The artist had argued that the photo series, which also included a photo of Barbie dolls wrapped in tortillas and covered in salsa in a casserole dish in a lit oven, was meant to critique the 'objectification of women' and 'beauty myth' associated with the popular doll."

As 2010 hits in full force I’m thinking of ways to schedule in more quality blog time and keep wordbit alive. In the meantime, here is my latest article on how to avoid cold and flu germs. I don’t know about you but I’ve run the germ gambit from Swine to March Madness varieties and I’ve had enough. So it’s apt then that my article recommends borderline conspiracy theory-fueled paranoid behaviour to avoid catching a sniffle.

Coercion#
Preliminaries#
What is coercion all about?#
The primary goal of coercion is to be able to transparently do arithmetic, comparisons, etc. between elements of distinct sets.
As a concrete example, when one writes \(1 + 1/2\) one wants to perform arithmetic on the operands as rational numbers, despite the left being an integer. This makes sense given the obvious and natural inclusion of the integers into the rational numbers. The goal of the coercion system is to facilitate this (and more complicated arithmetic) without having to explicitly map everything over into the same domain, and at the same time being strict enough to not resolve ambiguity or accept nonsense. Here are some examples:
sage: 1 + 1/2
3/2
sage: R.<x,y> = ZZ[]
sage: R
Multivariate Polynomial Ring in x, y over Integer Ring
sage: parent(x)
Multivariate Polynomial Ring in x, y over Integer Ring
sage: parent(1/3)
Rational Field
sage: x+1/3
x + 1/3
sage: parent(x+1/3)
Multivariate Polynomial Ring in x, y over Rational Field
sage: GF(5)(1) + CC(I)
Traceback (most recent call last):
...
TypeError: unsupported operand parent(s) for +: 'Finite Field of size 5' and 'Complex Field with 53 bits of precision'
Parents and Elements#
Parents are objects in concrete categories, and Elements are their members. Parents are first-class objects. Most things in Sage are either parents or have a parent. Typically whenever one sees the word Parent one can think Set. Here are some examples:
sage: parent(1)
Integer Ring
sage: parent(1) is ZZ
True
sage: ZZ
Integer Ring
sage: parent(1.50000000000000000000000000000000000)
Real Field with 120 bits of precision
sage: parent(x)
Symbolic Ring
sage: x^sin(x)
x^sin(x)
sage: R.<t> = Qp(5)[]
sage: f = t^3-5; f
(1 + O(5^20))*t^3 + 4*5 + 4*5^2 + 4*5^3 + 4*5^4 + 4*5^5 + 4*5^6 + 4*5^7 + 4*5^8 + 4*5^9 + 4*5^10 + 4*5^11 + 4*5^12 + 4*5^13 + 4*5^14 + 4*5^15 + 4*5^16 + 4*5^17 + 4*5^18 + 4*5^19 + 4*5^20 + O(5^21)
sage: parent(f)
Univariate Polynomial Ring in t over 5-adic Field with capped relative precision 20
sage: f = EllipticCurve('37a').lseries().taylor_series(10); f # abs tol 1e-14
0.997997869801216 + 0.00140712894524925*z - 0.000498127610960097*z^2 + 0.000118835596665956*z^3 - 0.0000215906522442708*z^4 + (3.20363155418421e-6)*z^5 + O(z^6) # 32-bit
0.997997869801216 + 0.00140712894524925*z - 0.000498127610960097*z^2 + 0.000118835596665956*z^3 - 0.0000215906522442708*z^4 + (3.20363155418427e-6)*z^5 + O(z^6) # 64-bit
sage: parent(f)
Power Series Ring in z over Complex Field with 53 bits of precision
There is an important distinction between Parents and types:
sage: a = GF(5).random_element()
sage: b = GF(7).random_element()
sage: type(a)
<class 'sage.rings.finite_rings.integer_mod.IntegerMod_int'>
sage: type(b)
<class 'sage.rings.finite_rings.integer_mod.IntegerMod_int'>
sage: type(a) == type(b)
True
sage: parent(a)
Finite Field of size 5
sage: parent(a) == parent(b)
False
However, non-Sage objects do not really have parents, but we still want to be able to reason with them, so their type is used instead:
sage: a = int(10)
sage: parent(a)
<... 'int'>
In fact, under the hood, a special kind of parent “The set of all Python objects of class T” is used in these cases.
Note that parents are not always as tight as possible.
sage: parent(1/2)
Rational Field
sage: parent(2/1)
Rational Field
Maps between Parents#
Many parents come with maps to and from other parents.
Sage makes a distinction between being able to convert between various parents, and coerce between them. Conversion is explicit and tries to make sense of an object in the target domain if at all possible. It is invoked by calling:
sage: ZZ(5)
5
sage: ZZ(10/5)
2
sage: QQ(10)
10
sage: parent(QQ(10))
Rational Field
sage: a = GF(5)(2); a
2
sage: parent(a)
Finite Field of size 5
sage: parent(ZZ(a))
Integer Ring
sage: GF(71)(1/5)
57
sage: ZZ(1/2)
Traceback (most recent call last):
...
TypeError: no conversion of this rational to integer
Conversions need not be canonical (they may for example involve a choice of lift) or even make sense mathematically (e.g. constructions of some kind).
sage: ZZ("123")
123
sage: ZZ(GF(5)(14))
4
sage: ZZ['x']([4,3,2,1])
x^3 + 2*x^2 + 3*x + 4
sage: a = Qp(5, 10)(1/3); a
2 + 3*5 + 5^2 + 3*5^3 + 5^4 + 3*5^5 + 5^6 + 3*5^7 + 5^8 + 3*5^9 + O(5^10)
sage: ZZ(a)
6510417
On the other hand, Sage has the notion of a coercion, which is a canonical morphism (occasionally up to a conventional choice made by developers) between parents. A coercion from one parent to another must be defined on the whole domain, and always succeeds. As it may be invoked implicitly, it should be obvious and natural (in both the mathematically rigorous and colloquial sense of the word). Up to inescapable rounding issues that arise with inexact representations, these coercion morphisms should all commute. In particular, if there are coercion maps \(A \to B\) and \(B \to A\), then their composites must be the identity maps.
Coercions can be discovered via the Parent.has_coerce_map_from()
method, and if needed explicitly invoked with the
Parent.coerce()
method:
sage: QQ.has_coerce_map_from(ZZ)
True
sage: QQ.has_coerce_map_from(RR)
False
sage: ZZ['x'].has_coerce_map_from(QQ)
False
sage: ZZ['x'].has_coerce_map_from(ZZ)
True
sage: ZZ['x'].coerce(5)

sage: ZZ['x'].coerce(5).parent()
Univariate Polynomial Ring in x over Integer Ring
sage: ZZ['x'].coerce(5/1)
Traceback (most recent call last):
...
TypeError: no canonical coercion from Rational Field to Univariate Polynomial Ring in x over Integer Ring
Basic Arithmetic Rules#
Suppose we want to add two element, a and b, whose parents are A and B
respectively. When we type a+b
then
If A
is
B, call a._add_(b)If there is a coercion \(\phi: B \rightarrow A\), call a._add_( \(\phi\) (b))
If there is a coercion \(\phi: A \rightarrow B\), call \(\phi\) (a)._add_(b)
Look for \(Z\) such that there is a coercion \(\phi_A: A \rightarrow Z\) and \(\phi_B: B \rightarrow Z\), call \(\phi_A\) (a)._add_( \(\phi_B\) (b))
These rules are evaluated in order; therefore if there are coercions in both directions, then the parent of a._add_b is A – the parent of the left-hand operand is used in such cases.
The same rules are used for subtraction, multiplication, and division. This logic is embedded in a coercion model object, which can be obtained and queried.
sage: parent(1 + 1/2)

Note that by github issue #14711 Sage’s coercion system uses maps with weak references to the domain. Such maps should only be used internally, and so a copy should be used instead (unless one knows what one is doing):

How to Implement#
Methods to implement#
Arithmetic on Elements:
_add_
,_sub_
,_mul_
,_div_
This is where the binary arithmetic operators should be implemented. Unlike Python’s
__add__
, both operands are guaranteed to have the same Parent at this point.Coercion for Parents:
_coerce_map_from_
Given two parents R and S,
R._coerce_map_from_(S)
is called to determine if there is a coercion \(\phi: S \rightarrow R\). Note that the function is called on the potential codomain. To indicate that there is no coercion from S to R (self), returnFalse
orNone
. This is the default behavior. If there is a coercion, returnTrue
(in which case an morphism usingR._element_constructor_
will be created) or an actualMorphism
object with S as the domain and R as the codomain.Actions for Parents:

Suppose one wants R to act on S. Some examples of this could be \(R = \QQ\), \(S = \QQ[x]\) or \(R = {\rm Gal}(S/\QQ)\) where \(S\) is a number field. There are several ways to implement this:
If \(R\) is the base of \(S\) (as in the first example), simply implement
_rmul_
and/or_lmul_
on the Elements of \(S\). In this caser * s
gets handled ass._rmul_(r)
ands * r
ass._lmul_(r)
. The argument to_rmul_
and_lmul_
are guaranteed to be Elements of the base of \(S\) (with coercion happening beforehand if necessary).If \(R\) acts on \(S\), one can define the methods
_act_on_
on Elements of \(R\) or_acted_upon_
on Elements of \(S\). In this caser * s
gets handled asr._act_on_(s, True)
ors._acted_upon_(r, False)
ands * r
asr._act_on_(s, False)
ors._acted_upon_(r, True)
. There is no constraint on the type or parents of objects passed to these methods; raise aTypeError
orValueError
if the wrong kind of object is passed in to indicate the action is not appropriate here.If either \(R\) acts on \(S\) or \(S\) acts on \(R\), one may implement
R._get_action_
to return an actualAction
object to be used. This is how non-multiplicative actions must be implemented, and is the most powerful and complete way to do things.
It should be noted that for the first way to work, elements of \(S\) are required to be ModuleElements. This requirement is likely to be lifted in the future.
Element conversion/construction for Parents: use
_element_constructor_
not__call__
The
Parent.__call__()
method dispatches to_element_constructor_
. When someone writesR(x, ...)
, this is the method that eventually gets called in most cases. See the documentation on the__call__
method below.
Parents may also call the self._populate_coercion_lists_
method in
their __init__
functions to pass any callable for use instead of
_element_constructor_
, provide a list of Parents with coercions to
self (as an alternative to implementing _coerce_map_from_
),
provide special construction methods (like _integer_
for ZZ),
etc. This also allows one to specify a single coercion embedding out
of self (whereas the rest of the coercion functions all specify maps
into self). There is extensive documentation in the docstring of the
_populate_coercion_lists_
method.
Example#
Sometimes a simple example is worth a thousand words. Here is a minimal example of setting up a simple Ring that handles coercion. (It is easy to imagine much more sophisticated and powerful localizations, but that would obscure the main points being made here.)
class Localization(Ring):
def __init__(self, primes):
"""
Localization of `\ZZ` away from primes.
"""
Ring.__init__(self, base=ZZ)
self._primes = primes
self._populate_coercion_lists_()
def _repr_(self):
"""
How to print self.
"""
return "%s localized at %s" % (self.base(), self._primes)
def _element_constructor_(self, x):
"""
Make sure x is a valid member of self, and return the constructed element.
"""
if isinstance(x, LocalizationElement):
x = x._value
else:
x = QQ(x)
for p, e in x.denominator().factor():
if p not in self._primes:
raise ValueError("Not integral at %s" % p)
return LocalizationElement(self, x)
def _coerce_map_from_(self, S):
"""
The only things that coerce into this ring are:
- the integer ring
- other localizations away from fewer primes
"""
if S is ZZ:
return True
elif isinstance(S, Localization):
return all(p in self._primes for p in S._primes)
class LocalizationElement(RingElement):
def __init__(self, parent, x):
RingElement.__init__(self, parent)
self._value = x
# We're just printing out this way to make it easy to see what's going on in the examples.
def _repr_(self):
return "LocalElt(%s)" % self._value
# Now define addition, subtraction, and multiplication of elements.
# Note that left and right always have the same parent.
def _add_(left, right):
return LocalizationElement(left.parent(), left._value + right._value)
def _sub_(left, right):
return LocalizationElement(left.parent(), left._value - right._value)
def _mul_(left, right):
return LocalizationElement(left.parent(), left._value * right._value)
# The basering was set to ZZ, so c is guaranteed to be in ZZ
def _rmul_(self, c):
return LocalizationElement(self.parent(), c * self._value)
def _lmul_(self, c):
return LocalizationElement(self.parent(), self._value * c)
That’s all there is to it. Now we can test it out:

Provided Methods#
__call__
This provides a consistent interface for element construction. In particular, it makes sure that conversion always gives the same result as coercion, if a coercion exists. (This used to be violated for some Rings in Sage as the code for conversion and coercion got edited separately.) Let R be a Parent and assume the user types R(x), where x has parent X. Roughly speaking, the following occurs:
If X
is
R, return x (*)If there is a coercion \(f: X \rightarrow R\), return \(f(x)\)
If there is a coercion \(f: R \rightarrow X\), try to return \({f^{-1}}(x)\)
Return
R._element_constructor_(x)
(**)
Keywords and extra arguments are passed on. The result of all this logic is cached.
(*) Unless there is a “copy” keyword like R(x, copy=False)
(**) Technically, a generic morphism is created from X to R, which may use magic methods like
_integer_
or other data provided by_populate_coercion_lists_
.coerce
Coerces elements into self, raising a type error if there is no coercion map.
coerce_map_from, convert_map_from
Returns an actual
Morphism
object to coerce/convert from another Parent to self. Barring direct construction of elements of R,R.convert_map_from(S)
will provide a callable Python object which is the fastest way to convert elements of S to elements of R. From Cython, it can be invoked via the cdef_call_
method.has_coerce_map_from
Returns
True
orFalse
depending on whether or not there is a coercion.R.has_coerce_map_from(S)
is shorthand forR.coerce_map_from(S) is not None
get_action
This will unwind all the
_get_action_, _rmul_, _lmul_, _act_on_, _acted_upon_, ...
methods to provide an actualAction
object, if one exists.
Discovering new parents#
New parents are discovered using an algorithm in
sage/category/pushout.py. The fundamental idea is that most Parents
in Sage are constructed from simpler objects via various functors.
These are accessed via the construction()
method, which returns a
(simpler) Parent along with a functor with which one can create self.
sage: CC.construction()
(AlgebraicClosureFunctor, Real Field with 53 bits of precision)
sage: RR.construction()
(Completion[+Infinity, prec=53], Rational Field)
sage: QQ.construction()
(FractionField, Integer Ring)
sage: ZZ.construction() # None
sage: Zp(5).construction()
(Completion[5, prec=20], Integer Ring)
sage: QQ.completion(5, 100, {})
5-adic Field with capped relative precision 100
sage: c, R = RR.construction()
sage: a = CC.construction()[0]
sage: a.commutes(c)
False
sage: RR == c(QQ)
True
sage: sage.categories.pushout.construction_tower(Frac(CDF['x']))
[(None,
Fraction Field of Univariate Polynomial Ring in x over Complex Double Field),
(FractionField, Univariate Polynomial Ring in x over Complex Double Field),
(Poly[x], Complex Double Field),
(AlgebraicClosureFunctor, Real Double Field),
(Completion[+Infinity, prec=53], Rational Field),
(FractionField, Integer Ring)]
Given Parents R and S, such that there is no coercion either from R to S or from S to R, one can find a common Z with coercions \(R \rightarrow Z\) and \(S \rightarrow Z\) by considering the sequence of construction functors to get from a common ancestor to both R and S. We then use a heuristic algorithm to interleave these constructors in an attempt to arrive at a suitable Z (if one exists). For example:
sage: ZZ['x'].construction()
(Poly[x], Integer Ring)
sage: QQ.construction()
(FractionField, Integer Ring)
sage: sage.categories.pushout.pushout(ZZ['x'], QQ)
Univariate Polynomial Ring in x over Rational Field
sage: sage.categories.pushout.pushout(ZZ['x'], QQ).construction()
(Poly[x], Rational Field)
The common ancestor is \(Z\) and our options for Z are \(\mathrm{Frac}(\ZZ[x])\) or \(\mathrm{Frac}(\ZZ)[x]\). In Sage we choose the later, treating the fraction field functor as binding “more tightly” than the polynomial functor, as most people agree that \(\QQ[x]\) is the more natural choice. The same procedure is applied to more complicated Parents, returning a new Parent if one can be unambiguously determined.
sage: sage.categories.pushout.pushout(Frac(ZZ['x,y,z']), QQ['z, t'])
Univariate Polynomial Ring in t over Fraction Field of Multivariate Polynomial Ring in x, y, z over Rational Field


CAST AWAY ---------
Chuck Noland (Tom Hanks) emphasizes the digital clock just installed in Fed Ex's newest office in Russia to his new hires in training. He calls his girlfriend Kelly (Helen Hunt) to rhapsodize over the fact that he's sorting packages within the shadows of Red Square, and that he'll be home for Christmas in Memphis in eighteen hours. At the extensive family dinner table, the troubleshooter is beeped for another emergency halfway around the world, forcing him to exchange gifts with Kelly in their car at the airport. She gives him a pocket watch containing her picture that had belonged to her grandfather. He gives her a package the size of a ring box, waves and declares 'I'll be right back!' in director Robert Zemeckis' "Cast Away."
Of course, Chuck isn't right back. The private FedEx plane he's on begins to encounter mechanical difficulties in a storm over the Pacific. Chuck risks hurtling objects to secure his new pocketwatch, then watches the sea approaching through the cockpit windshield. Miraculously, he finds his way out of the plane and inflates a life raft, which pulls him to the stormy surface. Luck is again on his side when he washes up on an abandoned beach. However, he quickly discovers the island is uninhabitted, so constructs a large help sign on the beach and begins to gather wreckage, packages and the one dead body which wash ashore in the aftermath of his crash.
Survival means learning how to open coconuts, catch fish, and make fire. As it begins to dawn on Chuck that his chances of rescue are slight (he figures out that the search area must be twice the area of Texas), he starts to open the FedEx packages he's neatly stacked and protected (ever the company man). A punk rock dress is turned into a fishing net; figure skates are used as cutting tools, and eventually, for dental surgery; video cassettes provide binding material. A volleyball, marked with Chuck's own handprint in blood, looks like a face and becomes Chuck's confident, Wilson. All the while, though, that precious picture of Kelly beckons and Chuck knows survival isn't enough - he has to attempt to save himself or die trying.
"Cast Away's" already gathered reams of press during its production due to the unusual nature of its shooting schedule. First, Hanks gained weight, ballooning over 200 lbs. The first half of the film was shot, then went on hiatus as Zemeckis went off and made "What Lies Beneath," while Hanks dieted almost fifty pounds off his frame and let his hair and beard grow wild. (The transition is handled unimaginatively in the film with a 'four years later' title card.)
Hanks deserves a lot of credit for tackling this role, not only for the physical hardships he endured. Yes, it's Best Actor nomination (and possibly a third win) time for America's favorite thespian again. For almost two hours of the film's 140 minute running time, Hanks is alone. His Chuck Nolan begins the film as a company guy who's always too on the move to stop and smell the roses. While he truly loves Kelly, he has trouble expressing emotion. On the island, he goes through hope, despair, frustration, industriousness, creativity, cowardice and courage. The man brings tears to your eyes over a *volleyball*.
Of the barely-there support, Hunt is fine. Better is Nick Searcy as Chuck's buddy Stan, who's losing his beloved wife of many years to cancer. Searcy is true support to Hanks, playing a man more in touch with life, ironically through approaching death, than pre-accident Chuck. And let's not forget Wilson, probably one of the best supporting inanimate object in film history.
Zemeckis' production is top notch, with ace lensing by Don Burgess ("What Lies Beneath") and tight editting by Arthur Schmidt. Alan Silvestri's score is simple, yet effective. Screenplay by Willian Broyles Jr. shows provides nice grace notes, such as the (Guardian) angels' wings which embellish the one package Chuck doesn't open, providing a connection from film's opening to closing. Time is measured in seconds, then in months.
"Cast Away" is a reflection upon what's really important in life and a showcase for Hanks' acting abilities.

Brazilian player sent off in Ukraine for reacting to racist insults
(Reuters) - Shakhtar Donetsk’s Brazilian midfielder Taison was sent off in a Ukrainian league match against visitors Dynamo Kiev on Sunday for reacting to racist insults from the crowd.
A video of the incident showed that Taison stuck his finger up at a section occupied by Dynamo fans and then hoofed the ball into the stands.
Taison, 31, who has featured six times for Brazil and has played in Ukraine since 2011, reacted with disbelief and left the field in tears.
The campaign group FARE (Football Against Racism in Europe) said on Twitter that Taison’s team mate and follow Brazilian Dentinho reported the insults to the referee and a stadium announcement was made.
Following UEFA-recommended protocol, the referee then took the players to the dressing-room for five minutes, FARE said, before dismissing Taison and restarting the game which Shakhtar won 1-0.
The third step of the protocol would have been to abandon the match.
“Third step not activated, victim of racism sent off,” said FARE, which added that Dynamo fans also mocked a club campaign by displaying posters which said “Like to racism.”
In 2015, Dynamo Kiev were ordered by UEFA to play two European matches behind closed doors after four black spectators were attacked at their stadium during a match against Chelsea.

Vaadin Grids are a power grid/table component based on Polymer. Vaadin Grids have a very robust feature set and are, therefore, the recommended grid component for use with WUF.
The @kion/vaadin-elements
from Common Components doesn't provide any packages itself.
Instead, it installs various package dependencies required for Vaadin components, like the Vaadin Grid.
It also declares a dependency on the @kion/kg-grid
component, which includes KION-specifc
styling for Vaadin Grids. By installing @kion/vaadin-elements
instead of the Vaadin Grid
components (and required dependencies) directy, you are ensuring that your Vaadin component versions
have been tested for compatibility with WUF and that style dependencies will be available.
Similary, the @kion/paper-elements
component from Common Components provides all of the
controls used within Vaadin Grid for column sort icon, column filters, etc.
$ yarn add @kion/kg-poly-vaadin-elements @kion/kg-poly-paper-elements
Then add the following lines to your application's app.module.ts

What is The New Year Clock?
The New Year Clock is a countdown clock to the new year created using JavaScript. It is intended to be viewed on a big screen or projector so everyone at your party can countdown together.
Is the time accurate?
The time displayed uses your computers clock to judge the time left until new year. If your computers clock is not set to the correct time then the countdown will be off. Set your computers clock to the correct time before using this program.
How do I use it?
Its as easy as clicking SHOW THE CLOCK on the home page, adjusting the font size, and making your browser display in full screen.
How do I change the font size?
In the top left corner there are some preset sizes as well as increment adjustments. Select the largest size while still keeping the font on the screen. Using the increment adjustments you can increas or decreas the font in incriments of 5.
How do I make my browser display full screen?
Each browser is slightly different. Most browsers you can press F11 to enter and exit full screen browsing. Some require you to go to your options menu. Best way to find out is google "[YOUR BROWSER HERE] fullscreen".


Your exercise is to enter two answers:
If the sensor output is 55, what should your estimate of the measurand be?
How would you represent this calibration as a function of the form x = f(M)? Enter your formula; for example “200 + 5 * M” (without the quote marks), and click the “show plot” button to see your calibration plotted and evaluated. You can enter powers of M using, e.g., M**2 or M^2. You can find a tool for performing basic linear-model fits to these calibration data under the “help with fitting” tab. Or, use MatLab or a similar package or your own calculations for fitting. Trial-and-error is instructive too. Given the assumed sensor precision, it should be possible to calibrate so that the standard deviation of the differences between the calibration and the function is about 0.30. See if you can reach that target.

I’ve created a repository with my basic files to format academic papers, including dissertations. Mine is a philosophy dissertation, but this should work for any work in humanities.
Writing a dissertation is hard; formatting all that content is hard in a totally different way. The goal of this template is to empower you to format your dissertation in a way that is beautiful, clean, and (relatively) easy by taking away some of the initial missteps and allowing you to troubleshoot your way forward.
The template is under construction and should be finished by the end of 2016. I’m also working on video instructions on how to put all the magic into use.
As a taste, this is the auto table of contents generated with a single click by Pandoc+Latex.

Active Learner — How Developers Keep Learning - by Dennis Nerush. Takeaway: “the kind of developers we want to hire and be part of our company and our teams … are not expert beginners and they are not necessary real experts. But they are aware of what they know and most importantly, what they don’t know. They are on the path to someday become real experts. To go in this path they cannot rely only on what their job teaches them and ‘out of the box’ just working solutions—they must actively learn.”
Are You out of Alignment? - by Camille Fournier. Takeaway: “Getting into alignment with the company is often a challenge for senior ICs because it requires a major change in focus. The hardest part is now identifying the right problem to solve, instead of solving the hardest problem. If you want to be able to find interesting work and also work on important things, you generally have to go find the interesting important things yourself. This requires that you to talk to a lot of people and listen to their problems, and then place a bet on a solution to one of these problems that will actually both be feasible but will also be seen as important.”
Can Metrics Be Used to Take Back Control of Your Software Delivery? - by Juan Pablo Buriticá. Takeaway: A straightforward, thorough post on different types of engineering metrics that teams can apply to measure their effectiveness meaningfully. Highlights Dr. Nicole Forsgren’s Accelerate as an influence, and also questions velocity as a meaningful metric in that it can be easily gamed. “The primary lesson I took from deploying delivery metrics was the importance of trust. For metrics to be successful, I needed my team to trust my intentions and embrace the strategy presented to them, especially when I didn’t have too many answers on the actual results we’d get.“
Cognitive Biases in Programming - by Yash Ranadive. Takeaway: Be mindful of hyperbolic discounting (going for an immediate payoff instead of a delayed larger one), the IKEA Effect (Overvaluing your own solutions to a problem, and thus in contrast undervalue other solutions), premature optimization (optimizing before you know that you need to), planning fallacy (optimistically underestimating the time required to complete a task), and recency bias (placing higher value on recent events than ones that occurred further in the past).
First Thoughts on Developer Gravity - by James Governor. Takeaway: A post that’s a kickoff to future exploration, but already offers insights about “developer gravitiy” (where devs “live”) and the importance of developer experience (which decreases with poor documentation, bug fixes and examples). “Developers are certainly not immune to the perception of momentum for environments they might target. Tensor Flow, for example, is seen as a hot technology. GitHub makes developer momentum more obvious than ever. 25k forks – sign me up! Developers want to adopt technologies than other developers find interesting. Herd mentality is a thing.”

Habits vs Goals: a Look at the Benefits of a Systematic Approach to Life - by Farnham Street. Practical advice about focusing on forming habits—which promote continuous improvement—instead of achieving goals, which have an endpoint.
Health Score Metrics as a Software Craftsmanship Enabler - by Chong Wang. Takeaway: About LinkedIn’s health score platform that “collects and presents craftsmanship-elevating metrics, and provides a framework for convenient extension.”
How Do I Convince…? - by Sandro Mancuso of Codurance. Takeaway: “One of the biggest mistakes we make as developers is to think that adopting certain practices is a goal that all teams and organisations should have. Technical practices and methodologies are a means to an end and not a goal on their own. They are the ‘how,’ not the ‘why.’ Before pushing a practice or methodology to a team or organisation, we should make sure that everyone understands the problem we are trying to solve - the ‘why.’ … Don’t discuss practices. Discuss the value you would like to provide and walk backwards.”
How Do You Know Your Code Is Bad? - by Dinesh Babu. Takeaway: “When you write code, ask yourselves these questions: Is this code too rigid? Is it possible to change the internals of this module in the future without touching the code in other modules and other layers? Is this code too fragile? Will it be hard to find all the places to refactor for any changes in the future? Should this feature be reusable? If so, does this code depends on any unwanted modules or frameworks that can be avoided?”
How to Level up as a Developer w/Scott Hanselman - by Niko. Takeaway: Fear and potential keep us from reaching our full potential. Learn how differentiate between doing the right things and doing things right.
Keep a Changelog - Olivier Lacan. An entire website dedicated to the art of the changelog, with an FAQ and an aim to produce a better changelog convention.
Notes to Myself on Software Engineering - by François Chollet. Takeaway: Lists of points on the development process, API design, and software careers. “Productivity boils down to high-velocity decision-making and a bias for action. This requires a) good intuition, which comes from experience, so as to make generally correct decisions given partial information, b) a keen awareness of when to move more carefully and wait for more information, because the cost of an incorrect decision would be greater than cost of the delay. The optimal velocity/quality decision-making tradeoff can vary greatly in different environments.”
On Writing Tech Specs - by Chuck Groom. Takeaway: “A tech spec forces you to think through complicated issues and to get everyone on the same page. This helps to avoid wasting time on dead-end solutions or building the wrong thing.”
Post-Commit Reviews - by Cindy Sridharan. Takeaway: “An alternative to pre-commit reviews is post-commit reviews, which lets a developer merge changes to trunk, and address reviewer comments in follow-up pull requests. In many ways, post-commit reviews offer the best of both worlds: developer velocity is not sacrificed at the altar of waiting for an approval, and reasonable concerns get addressed in short order by the developer in follow-up commits.” Includes guidance on how to overcome challenges.
Programming Beyond Practices: Be More Than Just a Code Monkey - by Gregory Brown. Covers all aspects of being a leader-developer besides writing code, from prototyping to improving processes.
Satisficery Engineering - by Paul Adams, Zalando. Takeaway: looks at the topic of “Push.” How do we know when to push a team—and in which direction? Sometimes asking a team to deliver more is appropriate but, likewise, it can also be appropriate to give them a break. This article is about being mindful of these opportunities and their consequences.
The Senior Engineer’s Guide to Helping Others Make Decisions - by Geeky. Takeaway: Lots of tips for mentoring junior devs on your team.
The Software Craftsman: Professionalism, Pragmatism, Pride - by Sandro Mancuso. An honest, engaging book that covers all imaginable aspects of being a craftsman, from playing an active role in shaping customer value to avoiding technical debt. Part of the Uncle Bob series.
Software Entropy Explained: Causes, Effects, and Remedies - by Adam Wasserman. Takeaway: “The primary goal is to create an awareness of software entropy because it is a factor in all forms of software development. Furthermore, we explore a means by which software entropy can be assigned a concrete value. Only by quantifying software entropy and observing its growth over successive releases can we truly understand the risk it poses to our current objectives and future plans.”
Speed in Software Development - by Michael Dubakov. Takeaway: “Software development pace / productivity / speed is a complex, interdependent and multifaceted concept. It has no easy solution. You can’t shout at people “work faster!” You can’t blindly cut corners and focus on value added activities only. The only solution is to think deeply about the company, development processes, people, tools, etc. Build a model and think."
Start from Square Zero: Hidden Habits You Need for a Successful Career in Tech - by Andrea Goulet. Takeaway: Stop calling yourself “non-technical,” pick a guilt language instead of a shame language, get comfortable with discomfort, mind the confidence gap, and acknowledge your biases.
Starting Up Security - by Ryan McGeehan. Takeaway: a collection of infosec resources to help teams manage risks. Includes post-mortems, risk assessment tools, and more.
We are All Product Owners! An Impact Guide for Engineers - by Eran Davidov. Takeaway: offers keen advice on how to measure impact, and what to measure.
What Can Developers Learn from Being on Call? - by Julia Evans. Takeaway: Based on a Twitter thread begun by Charity Majors, this post suggests that being on call helps you to learn what kinds of production problems are common and uncommon; understand what needs urgent attention; design reliable systems; build in monitoring and diagnostics early; understand the parts of the system that aren’t yours; gain confidence in your judgement; make minimum effective change; learn about distributed systems and consistency and race conditions, and become a better developer.
Agile Self-Assessment Game - by Ben Linders. Takeaway: playing the game enables teams to reflect on how they work together, discover how agile they are, and agree upon next steps they can take to increase their agility to deliver more value to their customers and stakeholders.

How to Build Ownership in Your Team – Case Study - by Michael Carr. Takeaway: Let the entire team to be involved in project inception, high-level backlog planning and prioritization; make teams cross-functional; be lean; and provide data so the team can understand the problem.
High Output Management for (Non-managing) Tech Leads - by Andrew Hao. Takeaway: Framed within a reference to Andy Grove’s High Output Management, this covers how tech leads can be effective. “Collaborate closely with your management counterpart to develop and contextualize these indicators … output indicators, quality indicators, in-process inspections.”
Hyperproductive Development - by Jessica Kerr. Takeaway: “the most productive development happens when one person knows the system intimately because they wrote it; this is in conflict with growing a system beyond what one person maintains.” The post offers suggestions for what teams can do.
Makers and Menders: Putting the Right Developers on the Right Projects (deck) - by Andrea Goulet, CEO & Co-Founder of Corgibytes. Takeaway: Makers and menders each have valuable roles to play in development. Focusing too much on making leads to maintenance, “legacy code,” and technical debt; mend as well to reduce your overhead.
9 Attributes of Successful Development Teams - by Rebecca Dodd at GitLab. Takeaway: Great teams automate everything, are meticulous about documentation, use collaboration tools and integrated platforms, version control everything, make it easy for everyone to contribute, spend time on side projects, make code review collaborative, and are allowed to be creative.
One Bite at a Time: Partitioning Complexity - by Kent Beck. Takeaway: tips on refactoring, code structure, and workflow.
That’s Not Our Code - by Norberto Herz. Takeaway: “Keeping the right mindset and the correct culture is key in order to have an organization that understands their boundaries and when it is right to cross them.” Hints at employing InnerSource, and addresses the conflicts and communication issues that can arise when autonomous teams are working in a microservices context.
25 Hints You’re Working on a High Performing Team - by John Cutler. Takeaway: Growth mindset, infrequent production issues, multidisciplinary collaboration, and 22 more signs.

A Crystal Ball to Prioritise Technical Debt in Monoliths or Microservices: Adam Tornhill’s Thoughts - by Daniel Bryant. Takeaway: a summary of Thornhill’s QCon London 2017 talk, which covered “methods to identify ‘hotspots’ of code complexity and churn; the benefit of continually evaluating the suitability of the architecture for the current system, for example, by examining ‘temporal coupling’ of components or microservices; and that the cost of inter-team coordination can often be learned from examining the social metadata associated with code commits within a version control system.”
A Seamless Way to Keep Track of Technical Debt in Your Source Code - by Philippe Bourgau. Takeaway: use TODO comments as a good starting point for tracking technical debt.
The Incredible Shrinking Time to Legacy. On Time to Suck as a Metric for Dev and Ops - by James Governor at RedMonk. Takeaway: “If we’re not running our own environments in house, operations disposability become increasingly realistic. Cattle not pets, for everything. But convenience and disposability always incur a cost.”
Paying off the Technical Debt in Your Agile Projects - by Nishi Grover Garg. Takeaway: “Just as you should not take out a financial loan without having a plan to pay it back, you should also have a plan when incurring technical debt. The most important thing is to have transparency—adequate tracking and visibility of the debt. Armed with the knowledge of these pending tasks, the team can devise a strategy for when and how to ‘pay off’ technical debt.”
Technical Debt: Adding Math to the Metaphor - by Donald Reinertsen. Takeaway: Explores differences between the usual financial debt metaphor for technical debt and what deferred work really means in product development. The main difference Reinertsen investigates involves the (missing) certainty of how much principal you gain and how much interest you will pay back (if at all).
Technical Debt Is Like a Tetris Game - by Jonathan Boccara. Takeaway: “If you’re asked to make a fix that will compromise the quality of your code, you can explain that it’s like placing a Tetris block at the wrong position. You can do it, and if you’re not too far into the game you won’t lose right now.”
When Your Tech Debt Comes Due - by Kevin Scott. Takeaway: a compelling story about how LinkedIn rebuilt their architecture in two months, and involved their entire engineering team.

\(L^2\) function is a function \(f: X \to \mathbb{R}\) that is square integrable: \(|f|^2 = \int_X |f|^2 d\mu\) with respect to the measure \(\mu\)
\(|f|\) is its \(L^2\)-norm
**measure ** = nonnegative real function from a delta-ring F such that \(m(\empty) = 0\) and \(m(A) = \sum_n m(A_n)\)
Hilbert space H: a vectors space with an innor product \(<f, g>\) such that the following norm turns H into a complete metric space: \(|f| = \sqrt{<f, f>}\)
diffeomorphism is an isomorphism of smooth manifolds. It is an invertible function that maps one differentiable manifold to another such that both the function and its inverse are smooth.

Lean, it's right there
I know you want (@add_group.to_add_monoid.{?l_1} ?m_2 ?m_3)
but isn't (@add_comm_monoid.to_add_monoid.{u₁} α₁
(@add_comm_group.to_add_comm_monoid.{u₁} α₁
(@module.to_add_comm_group.{u u₁} α α₁ (@comm_ring.to_ring.{u} α _inst_1) _inst_4))
good enough for you
they don't look the same to me
they're both justifying why I have addition
specifically here they're justifying why I have an add_monoid
can you do some BS "change" or "show" beforehand?
Is this one of these dreaded diamond things?
yes
I think the main concern is the one in the gsmul
thread
overloading is not good
This is Mario's doing, right?
So probably he will have some sensible solution
well but that bullet wasn't in the global namespace before Lean updated
oh so it's Leo's doing?
I would say so
So probably Mario will have some clever workaround.
I blame myself for all this
you?
I should never have mentioned that ^
had the wrong associativity
what happened
I got annoyed that 2^3^2
was 64 not 512
so I opened an issue
and all of a sudden there were lots of changes to ^
I see
https://github.com/leanprover/lean/issues/1951
led to https://github.com/leanprover/lean/commit/d387103aa2bebfc98220733d9607a16663ec1ef2
and then to https://github.com/leanprover/lean/commit/8f55ec4c50379c612731ced2424fd3eda0cf69a6
and hmm I don't see the bullet
maybe it's not my fault after all
nice to see presheaves being pulled into core lean though
https://github.com/leanprover/lean/commit/6e0bf8473b1980e6692a61a924b4c6eae195619d
oh
what a subversion
Talking of presheaves, thanks for trying to fix that tensor product file. Presumably that's where this issue arose.
I removed the has_smul
typeclass from group_power
, which should fix the notation overloading problem. This puts us back at square one local infix
type solutions for using gsmul
, but it shouldn't interfere with the module smul notation now. I'm not sure about registering every abelian group as a Z-module with an instance, since module still uses an out_param
for the scalar ring which might get stuck on int
