Template string interface. All templated values will be converted according to the rules of value by default. Use the other formatting methods attached to this object (e.g., csv, bool, id, etc) to achieve different output conversions.
sql`SELECT * FROM ${sql.id('users')} WHERE name = ${"Escaped '' Name"} AND expires_at < ${new Date()}`
// `SELECT * FROM "users" WHERE name = 'Escaped '''' Name' AND expires_at < '2019-03-17T14:52:04.221+00:00'`
Converts any given object into its SQL Boolean equivalent.
sql`SELECT ${sql.bool(true)}, ${sql.bool(null)}`
// `SELECT TRUE, FALSE`
the value to convert to boolean, according to Javascript boolean semantics
Converts an array of strings (or multi-part string ids as arrays) into a list of comma-separated SQL-safe ids. See id.
sql`SELECT ${sql.csids('id', ['tbl2', 'id'])} FROM tbl, tbl2`
// `SELECT "id", "tbl2"."id" FROM tbl, tbl2`
array of ids (strings or string arrays) to covert
Converts an array of objects into a comma-separated list of SQL-safe values. See value for conversion information.
sql`SELECT ${sql.csv([0, 1, 2])}`
// `SELECT 0, 1, 2`
array of values to convert
Given a plain javascript object, returns a list of that object's keys formatted as SQL ids. See id for details.
sql`INSERT INTO users(${sql.keys({ name: "joe", age: 23 })) ...`
// `INSERT INTO users("name", "age") ...`
Includes the provided string as raw, unescaped SQL.
const subQ = sql`SELECT * FROM users`
sql`SELECT COUNT(*) FROM (${sql.raw(subQ)})`
// SELECT COUNT(*) FROM (SELECT * FROM users)
Converts a date into a Postgres-formatted date string in the local timezone.
sql`SELECT ${sql.tz(new Date())}`
// `SELECT '2019-03-18T06:11:50.221+02:00'`
the date to convert
Converts a date into a Postgres-formatted date string in the UTC timezone.
sql`SELECT ${sql.tz(new Date())}`
// `SELECT '2019-03-18T08:11:50.221+00:00'`
the date to convert
Converts a value into its Postgres-escaped equivalent.
sql`SELECT * FROM users WHERE name = ${sql.value("James")}`
// `SELECT * FROM users WHERE name = 'James'`
Note that this is exactly equivalent to including the value directly:
sql`SELECT * FROM users WHERE name = ${"James"}`
Both will result in the same output. The value
method is
included only for explicitness, if desired. Conversion
rules are as follows:
Strings will be escaped.
sql`SELECT ${"Jim's Crab Shack"}`
// `SELECT 'Jim''s Crab Shack'`
Boolean values will be converted to TRUE/FALSE.
sql`SELECT ${true}, ${false}`
// `SELECT TRUE, FALSE`
Undefined objects will be converted to NULL.
sql`SELECT ${undefined}`
// `SELECT NULL`
Null values will be converted to NULL.
sql`SELECT ${null}`
// `SELECT NULL`
Numbers will be converted to their Postgres equivalents, including +Infinity, -Infinity, and NaN.
sql`SELECT ${10}, ${1.2}, ${Infinity}, ${0/0}`
// `SELECT 10, 1.2, '+Infinity', 'NaN'`
Arrays will be converted to string-formatted Postgres array literals,
with value conversions applied to each array element. The string form
is used because an empty SQL array (ARRAY[]
) without a specific
type is not allowed by Postgres.
sql`SELECT ${[0, "X", new Date()]}`
// `SELECT '{0, "X", "2019-03-18T08:11:50.221+00:00"}'`
Buffers will be converted to a hex-encoded Postgres escape string,
sql`SELECT ${Buffer.from('abc')}`
// `SELECT E'\\x616263'`
Date objects will be converted to a Postgres-compatible date string
according to the ConversionOpts convertDate
option provided to
build the sql sigil (defaults to dateToStringUTC).
sql`SELECT ${new Date()}`
// `SELECT '2019-03-18T08:11:50.221+00:00'`
Objects will be converted given the following rules:
If the object has a toPostgres
function, that function will be
called. If the object also has a rawType
attribute set to true,
then the results of the toPostgres
call will be included as
a raw string. Otherwise, the results of that call will be
processed as any other normal value
const cooked = { toPostgres: () => "str" }
sql`SELECT ${cooked}`
// `SELECT 'str'`
const raw = { toPostgres: () => "str", rawType: true }
sql`SELECT ${raw}`
// `SELECT str`
The above also applies if the object has the
Symbol.for('ctf.toPostgres')
and Symbol.for('ctf.rawType')
attributes defined. (See toPostgres and rawType, which
are importable symbols.)
const raw = { [toPostgres]: () => "str", [rawType]: true }
sql`SELECT ${raw}`
// `SELECT str`
Otherwise, the object will be converted via the ConversionOpts
convertObject
attribute used to build the SQL sigil. Defaults to
JSON.stringify
sql`SELECT ${{ name: "John's Chili Stop" }}`
// `SELECT '{"name": "John''s Chili Stop"}'`
the value to convert
Takes the values of the provided object and coverts them to their Postgres-value equivalents. Object values will be converted according to the rules of value.
Example:
sql`INSERT INTO users(name, age) VALUES(${sql.values({ name: "John", age: 23 }))
// `INSERT INTO users(name, age) VALUES('John', 23)`
Generated using TypeDoc
SQL templating function, with methods for specific conversions.

Google promises 14 more games by the end of 2019, and some of those include Ghost Recon Breakpoint, Rage 2, Metro Exodus and Wolfenstein Youngblood. Past that, titles like Watch Dogs Legion, Cyberpunk 2077, God and Monsters and Doom Eternal are coming to Stadia, the last of which was supposed to be a launch title before a delay.
But as you can see we are starting with a number of AAA titles that are at least a year or two old at this point, whether that’s Destiny 2, AC: Odyssey, Red Dead 2 and two Tomb Raiders. Mortal Kombat 11 was released this April, so it’s one of the newer, larger ones on the list. One you might never have heard of, GYLT, is a smaller, Stadia exclusive puzzle game.
This all does feel more like an early test run than the launch of a new console, which I think Google understands, though consumers may not. Granted, even new console launches don’t arrive with a ton of new games, but they are usually…new games, and that can only said about a couple smaller titles here with Stadia.
Ultimately, the goal with Stadia is clearly to get new releases arriving on the platform the same time that they arrive on PlayStation, Xbox or PC, though it may take some time to get to that point. Also, it sound be said once again, because I am still seeing people being confused, this is not Netflix-for-games which gets you all the titles on the list for a subscription fee. Rather, you still are buying individual games like you would on any other digital marketplace, outside of a few exceptions that will be offered for free when you subscribe to the 4K streaming tier.
Launch is a week away, and we’ll see how these games perform soon enough. Stay tuned.

Quantitative Genetics Graduate Education Module - Spring 2023
2023-04-02
Chapter 1 Course Overview
This is the complete set of course materials for the Quantitative Genetics Graduate Education Module (GEM) at the University of Oregon for the Spring of 2023. It is written in Markdown so that it can be easily updated.
In book you will find nearly all the information you will need to complete the course.


"Smart" Parsing
Inspiration
Smart parsing is, at its core, inspired by the idea of traits.
Traits are, at their core, extension interface. That is, they consist of an
interface definition (in Rust, they are defined against some unknown type
Self
), and some implementation of the trait for a type T
. Consider the
following Rust example, where Foo
is actually defined in some other
crate/package entirely:
struct SomeErrorType { ... }
trait Parseable {
fn parse(src: &'static str, ...) -> Self;
fn try_parse(src: &'static str, ...) -> Result<Self, SomeErrorType>;
}
impl Parseable for Foo {
fn parse(src: &'static str, ...) -> Foo {
return Foo::parse(src);
}
fn try_parse(src: &'static str, ...) -> Result<Foo, SomeErrorType> {
let fooParse = Foo::try_parse(src);
return match fooParse {
Ok(foo) => foo;
Err(error) => SomeErrorType::from_foo_error(error)
};
}
}
This is entirely valid for a Rust trait. The crate providing the Parseable trait
can provide implementations for types in other crates—for example, you
want to provide parsing helpers for things in the std
crate (Rust's standard
library).
The same thing might look like this in C#:
class SomeErrorType : Exception { ... }
trait interface IParseable<T> {
static T Parse(string src, ...);
static Result<T, SomeErrorType> TryParse(string src, ...);
}
trait class IParseable<Foo> {
static Foo Parse(string src, ...) {
return Foo.Parse(src, ...);
}
static Result<Foo, SomeErrorType> TryParse(string src, ...) {
// Notice this example calls the exception-throwing Parse method
// in order to get useful error output. :( This is because TryParse
// with a useful error via the Result type is not a pattern in .NET.
try {
return Foo.Parse(src, ...);
} catch (Exception e) {
return new SomeErrorType(e);
}
}
}
// Elsewhere...
public static class StringExtensions
{
public static T Parse<T>(this string src, params object[] args) {
// Implementation elided, but can check if `T` implements `IParseable<T>`
// or if it is provided by a trait, and call `Parse` via the interface.
…
}
}
Note that this is syntax I made up on the fly—it should not be taken as an endorsement of any kind, only wishful thinking.
With the trait in place, you can call "someString".TryParse<Foo>(…)
as if it
were a regular method, even if Foo
did not define Parse
or TryParse
. The
restrictions follow the same pattern as extension methods, but the method
appears on the type parameter T
.
The "smart" parsing implementation in Oxide allows a makeshift version of this.
It adds Parse<T>
and TryParse<T>
methods as extension methods on string
(as the above example does), and uses reflection to search for Parse
and
TryParse
methods. First, the given type T
is searched (in the case of
standard library types that provide those methods), and then, all loaded
assemblies are searched for extension methods.
This is not very performant the first time any type T
is used, as you might
imagine. Subsequent invocations are fast due to caching of the resulting
generated delegate.
This is not intended to be a seriously used API, and is likely to be removed in Oxide 2.0. In the meantime, it was fun writing it!

@import views.html.helpers.phpBlock @import org.joda.time.DateTime @(title: String, publishDate: DateTime, tags: List[String])
Many times when working with large web applications that expose web APIs to third party consumers, it is hard to tell what code might still be called from the client applications. A simple solution is to use loggers to track execution of specific blocks of code.
Let's say you have a RESTful controller in your code that handles posting new orders, but that API has been replaced by a new endpoint elsewhere and you want to make sure all clients get updated to use the new endpoint. At some point you'll want to make sure nobody is calling the old endpoint so that you can safely delete it without breaking clients. You can insert some logging code at the beginning of the endpoint controller like so:
@phpBlock( """ public function postOrder(Request $request, Logger $logger) { $app->getHitLogger()->log('postOrder() called by user ' . $app->getUser()->getId()); // Run code? or is dead?... } """ )Now we can leave this logging code in production for some time frame to see if the action is ever called. If is is the case that is this a deprecated API function, we may want to include the user identifying information so that we can notify them that they should upgrade their client code to a new endpoint.
If after the designated time frame (say, 1 month) there are no log entries recorded, we can safely delete the whole function and associated unit tests.
For complex systems, the same approach can be used to identify internal API calls that are no longer being used within the system. Depending on the language you are coding in, you might also be able to just run a code analysis tool that checks all paths through the code for functions called, but they don't necessarily catch calls in the code that are never reached.
Just be careful not to over-apply this technique and delete some block of code that might only be called under rare conditions =)

Boolean GCNListAdd( optr OD, /* optr to add to list */ ManufacturerID manufID, /* manufacturer ID of list */ word listType); /* list type */
This routine adds an object pointer (optr) to a GCN list interested in a particular change. The routine must be passed the optr to add, along with the
manufID
and the type of the list to add it to. If no list of the specified manufacturer and type currently exists, a new list will be created.
This routine will return
true
if the optr was successfully added to the GCN list and
false
if the optr could not be added. An optr cannot be added to a GCN list if it currently exists on that list.
Include: gcnlist.goh
Boolean GCNListAddHandles( MemHandle mh, /* handle of object to add */ ChunkHandle ch, /* chunk of object to add */ ManufacturerIDs manufID, /* manufacturer ID of list */ word listType); /* list type */
This routine is exactly the same as
GCNListAdd()
, except it takes the memory and chunk handles of the object rather than a complete optr.
Include: gcnlist.goh
Boolean GCNListAddToBlock( optr OD, /* optr of list to add */ ManufacturerID manufID, /* manufacturer ID of list */ word listType, /* list type */ MemHandle mh, /* handle of block holding list */ ChunkHandle listOfLists); /* chunk of list of lists * in block */
This routine adds a new GCN list to a block containing the GCN lists. Pass it the optr of the chunk containing the new GCN list as well as the list's type and manufacturer ID. Pass also the memory handle and chunk handle of the chunk containing the GCN "list of lists" which will manage the new list.
This routine returns true of the new optr is added to the GCN mechanism, false if it could not be added (if it was already there).
Warnings: This routine may resize chunks in the block, so you should dereference any pointers after calling this routine.
Include: gcnlist.goh
ChunkHandle GCNListCreateBlock( MemHandle mh); /* handle of the locked LMem block */
This routine creates a list of lists for the GCN mechanism. It is rarely, if ever, called by applications. Pass it the handle of the locked LMem block in which the list should be created.
Include: gcnlist.goh
void GCNListDestroyBlock( MemHandle mh, /* handle of locked block to * be destroyed */
ChunkHandle listOfLists); /* chunk of list of lists */
This routine destroys a GCN list of lists and all the GCN lists associated with it. Pass it the handle of the locked LMem block containing the lists as well as the chunk handle of the chunk containing the list of lists.
Include: gcnlist.goh
void GCNListDestroyList( optr list); /* optr of the GCN list to be destroyed */
This routine destroys the specified GCN list.
Include: gcnlist.goh
void GCNListRelocateBlock( MemHandle mh, /* handle of locked LMem block * containing GCN lists */
ChunkHandle listOfLists, /* chunk of list of lists */ MemHandle relocBlock); /* handle of block containing * relocation information */
This routine relocates the GCN list of lists in the specified block, updating all the optrs stored therein.
Warnings: This routine can resize and/or move the LMem block, so you should dereference pointers after calling it.
Include: gcnlist.goh
Boolean GCNListRemove( optr OD, /* the optr to be removed */ ManufacturerID manufID, /* manufacturer ID of the list */ word listType); /* list type */
This routine removes the passed optr from the specified GCN list. The routine must be passed the optr to remove along with the manufacturer ID and list type of the list to remove it from.
This routine will return
true
if the optr was successfully removed from the GCN list and
false
if the optr could not be found on the GCN list and therefore could not be removed.
Include: gcnlist.goh
Boolean GCNListRemoveFromBlock( optr OD, /* optr of GCN list to remove */ ManufacturerID manufID, /* manufacturer of list to remove */ word listType, /* type of list being removed */ MemHandle mh, /* handle of locked LMem block * containing the list of lists */
ChunkHandle listOfLists); /* chunk of list of lists */
This routine removes a GCN list from a GCN list block and from the list of lists therein.
Include: gcnlist.goh
Boolean GCNListRemoveHandles( MemHandle mh, ChunkHandle ch, ManufacturerID manufID, word listType);
This routine is exactly the same as
GCNListRemove()
, except it specifies the object to be removed via handles rather than an optr.
Include: gcnlist.goh

5 April 2012 - The Ministry of Health (MoH) of the Kingdom of Cambodia has announced a confirmed case of human infection with avian influenza A (H5N1) virus.
The 6 year-old female from Kampong Chhnang Province developed symptoms on 22 March 2012. After initial treatment at the village, she was later admitted to hospital in Phnom Penh on 28 March. She died on 30 March. Infection with avian influenza A (H5N1) virus was confirmed by Institut Pasteur du Cambodge on 30 March.
It was reported that the patient had contact with sick or dead poultry prior to onset of illness.
The National and local Rapid Response Teams (RRT) are conducting outbreak investigation and response following the national protocol. In addition, a public health education campaign is being conducted to inform families on how to protect themselves from contracting avian influenza.
To date, of the 20 cases reported in Cambodia since 2005, 18 have been fatal.

Ice - Albedo Feedback and runaway glaciation¶
Here we will use the 1-dimensional diffusive Energy Balance Model (EBM) to explore the effects of albedo feedback and heat transport on climate sensitivity.

Annual-mean model with albedo feedback: adjustment to equilibrium¶
A version of the EBM in which albedo adjusts to the current position of the ice line, wherever \(T < T_f\)
In [2]:

ASRequil = np.array(model1.ASR)
Integrating for 450 steps, 1826.211 days, or 5 years.
Total elapsed time is 5.0 years.
Let’s look at what happens if we perturb the temperature – make it 20ºC colder everywhere!
In [4]:
model1.Ts -= 20.
model1.compute_diagnostics()
Let’s take a look at how we have just perturbed the absorbed shortwave:
In [5]:
my_ticks = [-90,-60,-30,0,30,60,90]
lat = model1.domains['Ts'].axes['lat'].points
fig = plt.figure( figsize=(12,5) )
ax1 = fig.add_subplot(1,2,1)
ax1.plot(lat, Tequil, label='equil')
ax1.plot(lat, model1.Ts, label='pert' )
ax1.grid()
ax1.legend()
ax1.set_xlim(-90,90)
ax1.set_xticks(my_ticks)
ax1.set_xlabel('Latitude')
ax1.set_ylabel('Temperature (degC)')
ax2 = fig.add_subplot(1,2,2)
ax2.plot( lat, ASRequil, label='equil')
ax2.plot( lat, model1.ASR, label='pert' )
ax2.grid()
ax2.legend()
ax2.set_xlim(-90,90)
ax2.set_xticks(my_ticks)
ax2.set_xlabel('Latitude')
ax2.set_ylabel('ASR (W m$^{-2}$)')
plt.show()
So there is less absorbed shortwave now, because of the increased albedo. The global mean difference is:
In [6]:
global_mean( model1.ASR - ASRequil )
Out[6]:
Field(-20.37046205447195)
Less shortwave means that there is a tendency for the climate to cool down even more! In other words, the shortwave feedback is positive.
Recall that the net feedback for the EBM can be written
\(\lambda = - B + \frac{\Delta <(1-\alpha) Q >}{\Delta <T>}\)
where the second term is the change in the absorbed shortwave per degree global mean temperature change.
Plugging these numbers in gives
\(\lambda = - 2 + \frac{-20.4}{-20} = -2 + 1 = -1\) W m\(^{-2}\) \(^{\circ}\)C\(^{-1}\)
The feedback is negative, as we expect! The tendency to warm up from reduced OLR outweighs the tendency to cool down from reduced ASR. A negative net feedback means that the system will relax back towards the equilibrium.
Let’s let the temperature evolve one year at a time and add extra lines to the graph:
In [7]:
plt.plot( lat, Tequil, 'k--', label='equil' )
plt.plot( lat, model1.Ts, 'k-', label='pert' )
plt.grid()
plt.xlim(-90,90)
plt.legend()
for n in range(5):
model1.integrate_years(years=1.0, verbose=False)
plt.plot(lat, model1.Ts)
Temperature drifts back towards equilibrium, as we expected!
What if we cool the climate so much that the entire planet is ice covered?
In [8]:
model1.Ts -= 40.
model1.compute_diagnostics()
Look again at the change in absorbed shortwave:
In [9]:
global_mean( model1.ASR - ASRequil )
Out[9]:
Field(-108.99200830729608)
It’s much larger because we’ve covered so much more surface area with ice!
The feedback calculation now looks like
\(\lambda = - 2 + \frac{-109}{-40} = -2 + 2.7 = +0.7\) W m\(^{-2}\) \(^{\circ}\)C\(^{-1}\)
What? Looks like the positive albedo feedback is so strong here that it has outweighed the negative longwave feedback. What will happen to the system now? Let’s find out...
In [10]:
plt.plot( lat, Tequil, 'k--', label='equil' )
plt.plot( lat, model1.Ts, 'k-', label='pert' )
plt.grid()
plt.xlim(-90,90)
plt.legend()
for n in range(5):
model1.integrate_years(years=1.0, verbose=False)
plt.plot(lat, model1.Ts)
Something very different happened! The climate drifted towards an entirely different equilibrium state, in which the entire planet is cold and ice-covered.
We will refer to this as the SNOWBALL EARTH.
Note that the warmest spot on the planet is still the equator, but it is now about -33ºC rather than +28ºC!
Here Comes the Sun! Where is the ice edge?¶
The ice edge in our model is always where the temperature crosses \(T_f = -10^\circ\)C. The system is at equilibrium when the temperature is such that there is a balance between ASR, OLR, and heat transport convergence everywhere.
Suppose that sun was hotter or cooler at different times (in fact it was significantly cooler during early Earth history). That would mean that the solar constant \(S_0 = 4Q\) was larger or smaller. We should expect that the temperature (and thus the ice edge) should increase and decrease as we change \(S_0\).
\(S_0\) during the Neoproterozoic Snowball Earth events is believed to be about 93% of its present-day value, or about 1270 W m\(^{-2}\).
We are going to look at how the equilibrium ice edge depends on \(S_0\), by integrating the model out to equilibrium for lots of different values of \(S_0\). We will start by slowly decreasing \(S_0\), and then slowly increasing \(S_0\).

There are actually up to 3 different climates possible for a given value of \(S_0\)!
How to un-freeze the Snowball¶
The graph indicates that if the Earth were completely frozen over, it would be perfectly happy to stay that way even if the sun were brighter and hotter than it is today.
Our EBM predicts that (with present-day parameters) the equilibrium temperature at the equator in the Snowball state is about -33ºC, which is much colder than the threshold temperature \(T_f = -10^\circ\)C. How can we melt the Snowball?
We need to increase the avaible energy sufficiently to get the equatorial temperatures above this threshold! That is going to require a much larger increase in \(S_0\) (could also increase the greenhouse gases, which would have a similar effect)!
Let’s crank up the sun to 1830 W m\(^{-2}\) (about a 34% increase from present-day).
In [20]:
from climlab.process.process import process_like
model4 = process_like(model2) # initialize with cold Snowball temperature
model4.subprocess['insolation'].S0 = 1830.
model4.integrate_years(40)
#lat = model4.domains['Ts'].axes['lat'].points
plt.plot(model4.lat, model4.Ts)
plt.xlim(-90,90)
plt.ylabel('Temperature')
plt.xlabel('Latitude')
plt.grid()
plt.xticks(my_ticks)
plt.show()
print('The ice edge is at ' + str(model4.icelat) + 'degrees latitude.' )
Integrating for 3600 steps, 14609.688 days, or 40 years.
Total elapsed time is 4044.99999998 years.
The ice edge is at [-0. 0.]degrees latitude.
Still a Snowball... but just barely! The temperature at the equator is just below the threshold.
Try to imagine what might happen once it starts to melt. The solar constant is huge, and if it weren’t for the highly reflective ice and snow, the climate would be really really hot!
We’re going to increase \(S_0\) one more time...
In [21]:
model4.subprocess['insolation'].S0 = 1845.
model4.integrate_years(10)
plt.plot(lat, model4.state['Ts'])
plt.xlim(-90,90)
plt.ylabel('Temperature')
plt.xlabel('Latitude')
plt.grid()
plt.xticks(my_ticks)
plt.show()
Integrating for 900 steps, 3652.422 days, or 10 years.
Total elapsed time is 4054.99999998 years.
Suddenly the climate looks very very different again! The global mean temperature is
In [22]:
print( model4.global_mean_temperature() )
58.171701295
A roasty 60ºC, and the poles are above 20ºC. A tiny increase in \(S_0\) has led to a very drastic change in the climate.
In [23]:
S0array_snowballmelt = np.linspace(1400., 1900., 50)
icelat_snowballmelt = np.empty_like(S0array_snowballmelt)
icelat_snowballmelt_cooling = np.empty_like(S0array_snowballmelt)
for n in range(S0array_snowballmelt.size):
model2.subprocess['insolation'].S0 = S0array_snowballmelt[n]
model2.integrate_years(10, verbose=False)
icelat_snowballmelt[n] = np.max(model2.diagnostics['icelat'])
for n in range(S0array_snowballmelt.size):
model2.subprocess['insolation'].S0 = np.flipud(S0array_snowballmelt)[n]
model2.integrate_years(10, verbose=False)
icelat_snowballmelt_cooling[n] = np.max(model2.diagnostics['icelat'])
Now we will complete the plot of ice edge versus solar constant.
In [24]:
fig = plt.figure( figsize=(10,6) )
ax = fig.add_subplot(111)
ax.plot(S0array, icelat_cooling, 'r-', label='cooling' )
ax.plot(S0array, icelat_warming, 'b-', label='warming' )
ax.plot(S0array3, icelat3, 'g-', label='warming' )
ax.plot(S0array_snowballmelt, icelat_snowballmelt, 'b-' )
ax.plot(S0array_snowballmelt, icelat_snowballmelt_cooling, 'r-' )
ax.set_ylim(-10,100)
ax.set_yticks((0,15,30,45,60,75,90))
ax.grid()
ax.set_ylabel('Ice edge latitude', fontsize=16)
ax.set_xlabel('Solar constant (W m$^{-2}$)', fontsize=16)
ax.plot( [const.S0, const.S0], [-10, 100], 'k--', label='present-day' )
ax.legend(loc='upper left')
ax.set_title('Solar constant versus ice edge latitude in the EBM with albedo feedback', fontsize=16)
plt.show()
The upshot:
- For extremely large \(S_0\), the only possible climate is a hot Earth with no ice.
- For extremely small \(S_0\), the only possible climate is a cold Earth completely covered in ice.
- For a large range of \(S_0\) including the present-day value, more than one climate is possible!
- Once we get into a Snowball Earth state, getting out again is rather difficult!

This is a really cool web version of Conway's famous Game Of Life. The Game of Life is a cellular automaton devised by the British mathematician John Horton Conway way back in 1970.
The universe of the Game of Life is an infinite two-dimensional orthogonal grid of square cells, each of which is in one of two possible states, live or dead. Every cell interacts with its eight neighbors, which are the cells that are directly horizontally, vertically, or diagonally adjacent. At each step in time, the following transitions occur:

myList.innerHTML += "

In the above for loop, a reflow will be triggered for every iteration of the loop. 10 iterations cause 10 reflows.
var constructedHTML = "";
for (var i = 0, len = arr.length; i < len; i++) {
constructedHTML += "

"; //no reflow - appending to string
}
document.getElementById("myList").innerHTML = constructedHTML; //reflow
In this scenario, the elements are being constructed within a string. Not a single reflow is created by the loop, as the DOM is not being altered. Only once the array has been completely looped through is the string then applied as the innerHTML of an object, causing the only reflow of the function.

Infinispan's new server
One of the biggest changes in Infinispan 10 is the new server, which replaces the WildFly-based server we had been using up until 9.x.
This is the first of a series of blog posts which will describe the new server, how to use it, how to configure it and how to deploy it in your environment. More specifically, this post will focus mostly on the reasons behind the change, while the next ones will be of a more practical nature.
A history of servers
Infinispan has had a server implementing the Hot Rod protocol since 4.1. Originally it was just a main class which bootstrapped the server protocol. It was configured via the same configuration file used by the embedded library, it had no security and only handled Hot Rod.
Over time both a RESTful HTTP and a Memcached protocol were added and could be bootstrapped in the same way.
While the server bootstrap code was trivial, it was not going to scale to support all the things we needed (security, management, provisioning, etc). We therefore decided to build our next server on top of the very robust foundation provided by WildFly (aka, the application server previously known as JBoss AS 7), which made its first appearance in 5.3.
Integration with WildFly’s management model was not trivial but it gave us all of the things we were looking for and more, such as deployments, data sources, CLI, console, etc. It also came with a way to provision multiple nodes and manage them from a central controller, i.e. domain mode. All of these facilities however came at the cost of a lot of extra integration code to maintain as well as a larger footprint, both in terms of memory and storage use, caused by a number of subsystems which we had to carry along, even though we didn’t use them directly.
A different server
Fast-forward several versions, and the computing landscape has changed considerably: services are containerized, they are provisioned and managed via advanced orchestration tools like Kubernetes or via configuration management tools like Ansible and the model we were using was overlapping (if not altogether clashing) with the container model, where global configuration is immutable and managed externally.
With the above in mind, we have therefore decided to reboot our server implementation. During planning and development it has been known affectionately as ServerNG, but nowadays it is just the Infinispan Server. The WildFly-based server is now the legacy server.
Configuration
The new server separates global configuration (clustering, endpoints, security) from the configuration of dynamic resources like caches, counters, etc. This means that global configuration can be made immutable while the mutable configuration is stored separately in the global persistence location. In a containerized environment you will place the persistence location onto a volume that will survive restarts.
A quick two-node cluster with Docker
Starting a two-node cluster using the latest version of the server image is easy:
$ docker run --name ispn1 --hostname ispn1 -e USER=admin -e PASS=admin -p 11222:11222 infinispan/server $ docker run --name ispn2 --hostname ispn2 -e USER=admin -e PASS=admin -p 11322:11222 infinispan/server
The two nodes will discover each other, as can be seen from the logs:
15:58:21,201 INFO [org.infinispan.CLUSTER] (jgroups-5,ispn-1-42736) ISPN000094: Received new cluster view for channel infinispan: [ispn-1-42736|1] (2) [ispn-1-42736, ispn-2-51789] 15:58:21,206 INFO [org.infinispan.CLUSTER] (jgroups-5,ispn-1-42736) ISPN100000: Node ispn-2-51789 joined the cluster
Next we will connect to the cluster using the CLI:
$ docker run -it --rm infinispan/server /opt/infinispan/bin/cli.sh [disconnected]> connect http://<IP_ADDRESS>:11222 Username: admin Password: ***** [ispn-1-42736@infinispan//containers/DefaultCacheManager]>
Next we will create a distributed cache and select it for future operations:
[ispn-1-42736@infinispan//containers/DefaultCacheManager]> create cache --template=org.infinispan.DIST_SYNC distcache [ispn-1-42736@infinispan//containers/DefaultCacheManager]> cache distcache [ispn-1-42736@infinispan//containers/DefaultCacheManager/caches/distcache]>
Let’s insert some data now:
[ispn-1-42736@infinispan//containers/DefaultCacheManager/caches/distcache]> put k1 v1 [ispn-1-42736@infinispan//containers/DefaultCacheManager/caches/distcache]> put k2 v2 [ispn-1-42736@infinispan//containers/DefaultCacheManager/caches/distcache]> ls k2 k1 [ispn-1-42736@infinispan//containers/DefaultCacheManager/caches/distcache]> get k1 v1
Now let’s use the RESTful API to fetch one of the entries:
$ curl --digest -u admin:admin http://localhost:11222/rest/v2/caches/distcache/k2 v2
Since we didn’t map persistent volumes to our containers, both the cache and its contents will be lost when we terminate the containers.
In the next blog post we will look at configuration and persistence in more depth.

Rajasthan govt has zero tolerance policy on corruption: Ashok Gehlot
Gehlot said those who expose corruption will be given protection and their names will not be revealed in public.
by PTIRajasthan Chief Minister Ashok Gehlot on November 20 said his government has a zero-tolerance policy on corruption and anyone found involved in such acts will not be spared. During a review meeting of the Anti-corruption Bureau here, the CM said the vigilance wing of ACB should remain active and assured that it will get the resources needed, an official statement said.
“In order to provide accountable, sensitive and transparent governance, we have a zero tolerance policy towards corruption," the statement quoted Gehlot as saying.
Gehlot said those who expose corruption will be given protection and their names will not be revealed in public.
Gehlot suggested that there should be an ACB helpline number on the lines of police and ambulance services, the statement said.
He asked the ACB officials to effectively use the provisions of the anti-corruption law in order to ensure transparency in the administration.
Gehlot also issued directions for constituting a committee, headed by the chief secretary, to resolve issues related to ACB, the statement said.
Rajasthan Chief Secretary DB Gupta, senior officials of the home department were also present in the meeting, it said.

The youth fell back in the procession until the tattered soldier was not in sight. Then he started to walk on with the others.
But he was amid wounds. The mob of men was bleeding. Because of the tattered soldier’s question he now felt that his shame could be viewed. He was continually casting sidelong glances to see if the men were contemplating the letters of guilt he felt burned into his brow.
At times he regarded the wounded soldiers in an envious way. He conceived persons with torn bodies to be peculiarly happy. He wished that he, too, had a wound, a red badge of courage.
The spectral soldier was at his side like a stalking reproach. The man’s eyes were still fixed in a stare into the unknown. His gray, appalling face had attracted attention in the crowd, and men, slowing to his dreary pace, were walking with him. They were discussing his plight, questioning him and giving him advice. In a dogged way he repelled them, signing to them to go on and leave him alone. The shadows of his face were deepening and his tight lips seemed holding in check the moan of great despair. There could be seen a certain stiffness in the movements of his body, as if he were taking infinite care not to arouse the passion of his wounds. As he went on, he seemed always looking for a place, like one who goes to choose a grave.
Something in the gesture of the man as he waved the bloody and pitying soldiers away made the youth start as if bitten. He yelled in horror. Tottering forward he laid a quivering hand upon the man’s arm. As the latter slowly turned his waxlike features toward him the youth screamed:
“Gawd! Jim Conklin!”
The tall soldier made a little commonplace smile. “Hello, Henry,” he said.
The youth swayed on his legs and glared strangely. He stuttered and stammered. “Oh, Jim—oh, Jim—oh, Jim—”
The tall soldier held out his gory hand. There was a curious red and black combination of new blood and old blood upon it. “Where yeh been, Henry?” he asked. He continued in a monotonous voice, “I thought mebbe yeh got keeled over. There ’s been thunder t’ pay t’-day. I was worryin’ about it a good deal.”
The youth still lamented. “Oh, Jim—oh, Jim—oh, Jim—”
“Yeh know,” said the tall soldier, “I was out there.” He made a careful gesture. “An’, Lord, what a circus! An’, b’jiminey, I got shot—I got shot. Yes, b’jiminey, I got shot.” He reiterated this fact in a bewildered way, as if he did not know how it came about.
The youth put forth anxious arms to assist him, but the tall soldier went firmly as if propelled. Since the youth’s arrival as a guardian for his friend, the other wounded men had ceased to display much interest. They occupied themselves again in dragging their own tragedies toward the rear.
Suddenly, as the two friends marched on, the tall soldier seemed to be overcome by a tremor. His face turned to a semblance of gray paste. He clutched the youth’s arm and looked all about him, as if dreading to be overheard. Then he began to speak in a shaking whisper:
“I tell yeh what I’m ‘fraid of, Henry—I’ll tell yeh what I’m ‘fraid of. I ‘m ‘fraid I ‘ll fall down—an’ them yeh know – them damned artillery wagons—they like as not ‘ll run over me. That ’s what I ‘m ‘fraid of—”
The youth cried out to him hysterically: “I ‘ll take care of yeh, Jim! I ‘ll take care of yeh! I swear t’ Gawd I will!”
“Sure—will yeh, Henry?” the tall soldier beseeched.
“Yes—yes—I tell yeh—I’ll take care of yeh, Jim!” protested the youth. He could not speak accurately because of the gulpings in his throat.
But the tall soldier continued to beg in a lowly way. He now hung babelike to the youth’s arm. His eyes rolled in the wildness of his terror. “I was allus a good friend t’ yeh, wa’n’t I, Henry? I ‘ve allus been a pretty good feller, ain’t I? An’ it ain’t much t’ ask, is it? Jest t’ pull me along outer th’ road? I’d do it fer you, wouldn’t I, Henry?”
He paused in piteous anxiety to await his friend’s reply.
The youth had reached an anguish where the sobs scorched him. He strove to express his loyalty, but he could only make fantastic gestures.
However, the tall soldier seemed suddenly to forget all those fears. He became again the grim, stalking specter of a soldier. He went stonily forward. The youth wished his friend to lean upon him, but the other always shook his head and strangely protested. “No—no—no—leave me be—leave me be—”
His look was fixed again upon the unknown. He moved with mysterious purpose, and all of the youth’s offers he brushed aside. “No—no—leave me be—leave me be—”
The youth had to follow.
Presently the latter heard a voice talking softly near his shoulder. Turning he saw that it belonged to the tattered soldier. “Ye’d better take ‘im outa th’ road, pardner. There’s a batt’ry comin’ helitywhoop down th’ road an’ he ‘ll git runned over. He ’s a goner anyhow in about five minutes—yeh kin see that. Ye ‘d better take ‘im outa th’ road. Where th’ blazes does hi git his stren’th from?”
“Lord knows!” cried the youth. He was shaking his hands helplessly.
He ran forward presently and grasped the tall soldier by the arm. “Jim! Jim!” he coaxed, “come with me.”
The tall soldier weakly tried to wrench himself free. “Huh,” he said vacantly. He stared at the youth for a moment. At last he spoke as if dimly comprehending. “Oh! Inteh th’ fields? Oh!”
He started blindly through the grass.
The youth turned once to look at the lashing riders and jouncing guns of the battery. He was startled from this view by a shrill outcry from the tattered man.
“Gawd! He’s runnin’!”
Turning his head swiftly, the youth saw his friend running in a staggering and stumbling way toward a little clump of bushes. His heart seemed to wrench itself almost free from his body at this sight. He made a noise of pain. He and the tattered man began a pursuit. There was a singular race.
When he overtook the tall soldier he began to plead with all the words he could find. “Jim—Jim—what are you doing—what makes you do this way—you’ll hurt yerself.”
The same purpose was in the tall soldier’s face. He protested in a dulled way, keeping his eyes fastened on the mystic place of his intentions. “No—no—don’t tech me—leave me be—leave me be—”
The youth, aghast and filled with wonder at the tall soldier, began quaveringly to question him. “Where yeh goin’, Jim? What you thinking about? Where you going? Tell me, won’t you, Jim?”
The tall soldier faced about as upon relentless pursuers. In his eyes there was a great appeal. “Leave me be, can’t yeh? Leave me be for a minnit.”
The youth recoiled. “Why, Jim,” he said, in a dazed way, “what ’s the matter with you?”
The tall soldier turned and, lurching dangerously, went on. The youth and the tattered soldier followed, sneaking as if whipped, feeling unable to face the stricken man if he should again confront them. They began to have thoughts of a solemn ceremony. There was something rite-like in these movements of the doomed soldier. And there was a resemblance in him to a devotee of a mad religion, blood-sucking, muscle-wrenching, bone-crushing. They were awed and afraid. They hung back lest he have at command a dreadful weapon.
At last, they saw him stop and stand motionless.  His spare figure was erect; his bloody hands were quietly at his side. He was waiting with patience for something that he had come to meet. He was at the rendezvous. They paused and stood, expectant.
There was a silence.
Finally, the chest of the doomed soldier began to heave with a strained motion. It increased in violence until it was as if an animal was within and was kicking and tumbling furiously to be free.
This spectacle of gradual strangulation made the youth writhe, and once as his friend rolled his eyes, he saw something in them that made him sink wailing to the ground. He raised his voice in a last supreme call.
“Jim—Jim—Jim—”
The tall soldier opened his lips and spoke. He made a gesture. “Leave me be—don’t tech me—leave me be—”
There was another silence while he waited.
Suddenly his form stiffened and straightened. Then it was shaken by a prolonged ague. He stared into space. To the two watchers there was a curious and profound dignity in the firm lines of his awful face.
He was invaded by a creeping strangeness that slowly enveloped him. For a moment the tremor of his legs caused him to dance a sort of hideous hornpipe. His arms beat wildly about his head in expression of implike enthusiasm.
His tall figure stretched itself to its full height. There was a slight rending sound. Then it began to swing forward, slow and straight, in the manner of a falling tree. A swift muscular contortion made the left shoulder strike the ground first.
The body seemed to bounce a little way from the earth. “God!” said the tattered soldier.
The youth had watched, spellbound, this ceremony at the place of meeting. His face had been twisted into an expression of every agony he had imagined for his friend.
He now sprang to his feet and, going closer, gazed upon the pastelike face. The mouth was open and the teeth showed in a laugh.
As the flap of the blue jacket fell away from the body, he could see that the side looked as if it had been chewed by wolves.
The youth turned, with sudden, livid rage, toward the battlefield. He shook his fist. He seemed about to deliver a philippic.
“Hell—”
The red sun was pasted in the sky like a wafer.

Features
Thanks for installing the Landmarks extension. With it, you can…
- Quickly check how many landmark regions the page has, via the toolbar icon.
- Explore landmarks via keyboard shortcuts.
- Explore landmarks via the toolbar pop-up.
- Explore landmarks via the browser sidebar (Firefox and Opera only).
- Use the developer tools panel to inspect the code behind landmark regions.
You can change the following preferences.
- How long the border is shown.
- The border's colour.
- The font size of the in-page landmark labels.
Subtle details
If a page lacks an author-specified "" landmark region, the extension will attempt to guess where it might be. Likewise if the author didn't specify any "" regions, the extension will try to guess those. The guesses are based on commonly-used element id
and class
attribute values.
Each page is meant to have only one "" region, however some pages do have more than one. In this case, using the "" will cycle between them.
What's new?
New in version …
- Add an option to close the pop-up when activating one of the buttons. Thanks to GitHub user kimviens for the feedback.
- Visually highlight landmarks when their corresponding buttons in the sidebar (Firefox) or pop-up (all browsers) are focused/hovered. A couple more details…
- The page won't scroll when highlighting landmarks in this way, to prevent jumpiness.
- The rate at which the highlights are applied/removed is capped, to prevent excessive flashing.
- Ensure that the border font size setting can't be left empty (if the user empties it, use the default setting).
For full details, consult the change log.
About landmark regions, for authors and developers
Landmark regions can really help people get a quick overview of your content, and navigate it much more effectively. This can save them a lot of time, so please consider implementing landmarks on your site. If you’re using HTML5, you’ll almost certainly have some landmarks already, but there are some things you need to know; the info below will help you ensure your landmarks are as helpful as possible.
- All about landmark regions, and some golden rules (story and slides for my a11yTOConf talk)
- Léonie Watson demonstrates landmarks (video)
- W3C ARIA landmarks example and advice page
- Easy content organisation with HTML5 (The Paciello Group ’blog article)
- Using WAI-ARIA landmarks (The Paciello Group ’blog article)
Please bear in mind the following when implementing landmarks…
It’s important that landmarks are not over-used, because their power comes from providing a concise overview of the content of the page. The heading hierarchy for the page can be relied upon for more fine-grained navigation within a particular area of a page.
Rule of thumb: Use as few landmarks as possible, but ensure that all of the content on the page is within a landmark region.
If you’re using HTML5 elements such as
<header>
,<nav>
,<main>
and others, then your page will inherit some landmarks automagically. However it can be really helpful to label them (especially if there’s more than one landmark of the same type on a page, such as a separate site-wide and page-local<nav>
). The W3C documentation has all the details, but essentially you would use either thearia-labelledby
oraria-label
attribute.Rule of thumb: If you’ve more than one landmark of the same type, then be sure to label them, so their purpose is clear.
This extension's support for landmark regions
The Landmarks extension uses the Page Structural Semantics Scanner Tests suite; you can find information on standards support there.

[gecode-users] Schedule Branching Recommendations

I am in a similar situation now. Could you please explain why (if this
is the case indeed) is it not possible to just share the data in some
raw data structure inside the Space? I mean, in the above mentioned
case, propagation computes some information that can be re-used in the
branching. I was under the impression that the following might work in
similar cases:
- During propagation, store (overwrite) some "raw" data in the Space
instance (I know, this is not exactly a good architecture design...)
- As soon as the Space is stable, the system looks for active
branchings, asking for alternatives
- The branching might access the data now, knowing that it is the result
of the last propagation (which led to the fixpoint), and return some
alternatives
The thing I'm not sure about is whether there must always be a
propagation step after recomputation. In case that not, the branching
should have the possibility to compute the data from scratch, using only
the variables' domains (in this case, copying the space should
invalidate the data to make sure it is recomputed).
The reason I believe this could work is that the shared information is
after all just some kind of cache which reflects the current domains.
Thanks for any comments,
Filip
